Vapor extraction device, in particular trough ventilation device
The invention relates to a fume extraction device, in particular a depression ventilation device.
In extractor devices, in particular in Muldenlüftungen, which are also referred to as table vents, an air inlet is provided in the vicinity of the hearth or workplace in the work surface, can enter through the air in the extractor device. For this purpose, a fan is provided below the cooking field level. This blower creates an oppressor, through which the air is sucked from the stove or workplace. In such extractor devices, it is known to provide the air inlet, which is also referred to as the suction port, with a closing element. As a result, the suction opening can be closed, in particular, when the extractor device is not in operation, thus preventing the entry of contaminants into the extractor device. In known extractor devices for this purpose, for example, a sheet whose size is slightly larger than the surface of the suction port, placed on the suction port. In the sheet metal, an engagement opening is preferably provided, in which the user can engage to remove the sheet. Such a closure element is disclosed for example in DE 10 2009 025 038 A1. A disadvantage of this type of extractor device is that the opening and closing of the intake opening is expensive, since the sheet must be aligned with the intake and on this or exactly inserted into this and also the user after removing the sheet on another Stow away place.
Furthermore, a vapor extraction device is described in the earlier application DE 10 2012 206 255.6, in which a rotatably mounted closing element is provided. In this extractor device, a connecting element is attached to a transmission element on the shaft of the closing element, which in turn acts on at least one spring element.
Object of the present invention is to provide a fume extraction device in which the suction port can be closed in a simple manner, at least temporarily reliable, which can be operated in a simple manner and yet has a simple structure.
The invention is based on the finding that this object can be achieved by a fixing mechanism is provided, via which a closing element can be held in different positions, in which the closing element itself serves as an actuating element for the fixing mechanism and in which a transmission element is used, which can perform several functions.
The object is therefore achieved by a fume extraction device, in particular trough ventilation device, having at least one suction opening, at least one closing element for at least temporarily closing the suction opening and a fixing mechanism for fixing the closing element. The extractor device is characterized in that the closing element is rotatably mounted in the region of the suction opening via a shaft, that the closing element for actuating the fixing mechanism, that the fixing at least one fixing means for fixing the Verschließelementes in at least two defined rotational positions and at least one control element for controlling the Movement of the closing element comprises and that the fixing mechanism has a transmission element which is provided on the shaft of the closing element and that at least one fixing means engages the transmission element and at least one control element at least temporarily comes into contact with the transmission element.
In the context of the invention, a vapor extraction device is understood in particular to be a vapor extraction device for sucking out fumes and vapors from a stove or another workstation in a kitchen. Preferably, the vapor extraction device is understood to be a hollow ventilation device, which will also be referred to below as a tray ventilator or table ventilator. Such a hollow ventilator is characterized in that it is sucked in by air from the stove or hob or in the region of the cooker or hob and is directed downwards, preferably vertically downwards, from the suction opening, via which the air enters the extractor device. The suction opening is located in these hollow ventilators preferably in the
Horizontal and is located adjacent to the stove, the hob, the hob or the workplace.
As a closing element, which is also referred to below as a closure element, is understood in the context of the present invention, an element by means of which a suction port of a fume extractor at least temporarily completely covered, that is can be closed. The suction opening of the extractor device according to the invention is understood to be the opening through which air can enter the extractor device when the closing element is not provided. The suction opening preferably represents an elongated opening, in particular a rectangular opening. In the flow direction behind the suction opening and in the case of tray fans, thus under the suction opening, at least one filter element is preferably provided. At the extractor device according to the invention can be provided a plurality of suction. In this case, at least one and preferably exactly one closing element is provided in each intake opening.
For the purposes of the present invention, a fixing mechanism is understood to mean a mechanism by means of which the closing element can be held in at least one position in the suction opening. Furthermore, the fixing mechanism can preferably also serve to release a fixation of the closing element in a position and to move the closing element. The fixing mechanism may also include holders for mounting or attachment and in particular storage of the closing element. These holders, which are also referred to as holding means, but may also be provided separately, but then connected to the fixing mechanism.
According to the invention, the closing element is rotatably mounted in the region of the suction opening via a shaft. The bearing is preferably detachable, so that the closing element can be removed from the suction opening. The axis of rotation of the closing element lies in or preferably parallel to the suction opening. Thus, the axis of rotation is at a Muldenlüftungsvorrichtung in the horizontal. In the region of the intake opening means in this context that the storage of the closing element in or near the suction port, preferably in
Flow direction after the suction port, is provided on the extractor device.
The closing element is used according to the invention for actuating the fixing mechanism. As an operation of the fixing mechanism is understood in the context of the invention, an influence on the fixing mechanism by which the closing element is either fixed in one position or an existing fixation of the closing element is released in one position. Since this influence can be effected by the closing element, the closing element can also be referred to as an actuating element. Preferably, the actuation of the fixing mechanism is effected by applying pressure to the closing element and particularly preferably by rotating the closing element.
According to the invention, the fixing mechanism comprises fixing means for fixing the closing element in at least two defined rotational positions. The fixing means are also referred to below as fixing elements. As a rotational position in this case the position of the closing element is referred to in an angular position. Defined rotational positions are positions which are predetermined or can be predefined and can be set in a targeted manner. In contrast to the setting of any positions of the closing element states of the extractor device can thus be specified in the extractor device according to the invention, wherein the rotational position of the closure element is predetermined for adjusting the state of the extractor device.
The one or more fixing means may comprise spring elements. According to one
Embodiment, the fixing means for fixing the closing element comprises a catch. As a rest is understood in the context of the invention, in particular a locking recess or detent recess. Since the fixing means is provided for fixing the closing element in a defined rotational position, can thus via a catch the
Closing element in a locked position and a further detent in one
Operating position are kept. The advantage of providing a detent is that the user of the extractor device can thereby also be given a haptic feedback that the closing element is in one of the defined rotational positions. As an alternative to a rest, however, it is also possible that other fixing means are provided which hold the closing element in one of the defined rotational positions. These may be in particular fixing means which hold the closing element by magnetic force or spring force in the defined rotational position.
According to the invention, at least one of the fixing elements is preferably a spring element for applying a rotational force to rotate the closing element. Preferably, at least two spring elements are provided whose spring forces are offset from one another, that is, inclined, directions. In this way, by a spring element, for example, a sliding element can be pulled into a detent, by which the first rotational position is defined. By the other spring element, the lubricant is then held in another catch, by which the second rotational position is defined. But the spring element or the spring elements can also serve alone as a fixing means to hold the closing element in a rotational position. When providing two spring elements, this rotational position can be such that both spring elements are relaxed in this rotational position. This rotational position may, for example, be a removal position of the closing element lying between a blocking position and an operating position. In addition, according to the invention, however, the spring element preferably also serves for applying a rotational force to the closing element, by means of which the closing element is rotated. This rotational force can be transmitted from the spring element to the closing element by parts of the fixing mechanism, in particular by the transmission element rigidly connected to the shaft.
In addition, the fixing mechanism has at least one control element for controlling the movement of the closing element. For the purposes of the invention, a control element is in particular an element by means of which the movement of the closing element can be monitored and / or influenced, in particular slowed down or obstructed. Preferably, the at least one control element controls the movement of the closing element between the defined rotational positions.
Furthermore, the fixing mechanism has a transmission element which is provided on the shaft of the closing element. As a transmission element, a force transmission element is referred to, which preferably represents a planar element, wherein the shaft is perpendicular to the surface of the transmission element. At the transmission element engages a fixing means and at least one control element comes at least temporarily in contact with the transmission element. The transmission element is preferably connected to the shaft in such a way that the shaft is also moved by movement of the transmission element. In addition, the shaft and thereby the transmission element is preferably moved by movement of the closing element. When engaging the fixing means to the transmission element according to the invention the engagement in or the force is referred to at least one point of the transmission element. The at least temporarily coming into contact of the control element with the transmission element is preferably carried out by movement of the transmission element.
Force can be transmitted from the closing element to at least one of the fixing means by the transmission element. In this case, the fixing means may be, for example, a sliding element in the form of a pin which is guided in a guide element to form a link which may comprise the detent or another fixing means. The transmission element is preferably an elongated transmission element, for example a Hebei or pendulum. The transmission element preferably extends perpendicular to the axis of rotation of the closing element. This makes it possible, the locations at which the fixing means must be provided to the axis of rotation of the closing element spaced or offset to arrange the transmission element. Thus, the defined rotational positions can be set more accurately than is possible with a provision of fixing means on the axis of rotation. In addition, a lever arm can be created by the transmission element, through which the force that is necessary on the closing element for fixing or releasing the fixation is reduced.
By providing a transmission element on the shaft and engaging at least one fixing means to the transmission element and coming into contact with at least one control element, the operation of the fixing mechanism and thus the setting of the defined rotational position of the closing element are simplified. In addition, the structure of the fixing mechanism is simplified by a direct engagement of at least two fixing means on the transmission element. Thus, as a fixing means, for example spring elements act directly on different points of attack on the transmission element and thereby influence the rotational position of the transmission elements, about the rotational position of the shaft and about the rotational position of the closing element. By also be able to attack control elements on the same transmission element, the structure is further simplified.
By also in the extractor device according to the invention by the rotatably mounted locking element, the actuation of the fixing mechanism can be effected and are fixed by this different rotational positions of the closing element, it is possible for the user of the extractor device in a simple manner different states of the extractor device. In particular, the closing of the suction opening by the closing element can be canceled by the user by rotating the closing element about its axis of rotation, and the suction opening can thus be used for sucking air from a work surface or a stove. Separate controls or actuators, such as buttons, this are not required. In addition, the predetermined rotational positions of the closing element and thus the different states of the extractor device can be adjusted without the closure element having to be removed from the suction opening.
According to one embodiment, at least one control element comes into contact with the edge region of the transmission element. By using the edge region for contact with the control element, the surface of the transmission element is available for engaging or engaging further control elements or fixation means. According to a preferred embodiment, the at least one fixing agent engages or engages in the surface of the transmission element. By utilizing the surface of the transfer member, the engagement of a fixing agent can be guided in the surface. The engagement of fixatives in the surface has the advantage that no projection over the edge of the transmission element is required and so the required space for the fixing mechanism is minimized.
According to one embodiment, one of the control elements or the control element is a part of a brake element. In this embodiment, the
Control element preferably a gear or partial gear, which can engage with a toothing on the transmission element. The toothing is preferably provided at the edge of the transmission element. By the braking element, the movement of the transmission element can be slowed down. In particular, the movement between the defined rotational positions of the closing element is slowed down. By the braking element acts on the same transmission element, which also acts on other fixing means, such as spring elements, which causes or supports the motive force to move the fixing in one of the defined rotational positions, the effect of opposing forces of the motive force and the braking force can each other reliably and done quickly. In addition, by providing a contact region, in particular a toothing, on the transmission element for the brake element only one component namely a gear or partial gear is required and the structure of the fixing mechanism is further simplified.
According to another embodiment, at least one of the control elements is a switch which is actuated by the transmission element. Preferably, the switch is actuated by the edge region of the transmission element or by the back of the transmission element in the edge region. The switch, which can be actuated by the transmission element, preferably represents a signaling switch. By means of this signaling switch, the position of the closing element can be signaled to an electronics of the extractor device. Since the movement of the closing element, which is rigidly connected to the shaft, leads to a movement of the transmission element which is also rigidly connected to the shaft, by detecting the movement of the transmission element, the position of the closing element via the actuated by the transmission element switch to the Electronics are reported. The switch is preferably positioned so that it is actuated in a rotational angle range of several degrees about the defined rotational positions of the closing element.
According to a further embodiment, at least one of the control elements constitutes a locking pin for blocking the movement of the closing element. A locking pin is hereby designated a pin which can be at least partly inserted into the transmission element or can rest against the edge of the transmission element and thereby prevent a rotational movement of the transmission element , The locking pin is preferably provided only temporarily. In particular, the locking pin can be provided for assembly purposes. According to one embodiment, the transmission element has at least one receiving opening for receiving at least part of the locking pin. The receiving opening is provided in the surface of the transmission element or at the edge and extends perpendicular to the surface. In this way, the locking pin can be provided on the transmission element, that this projects beyond the transmission element and comes into contact with a further part of the fixing mechanism and thus forms a stop which stops the movement of the transmission element.
According to one embodiment, the transmission element has a region for engagement with a part of a control element which constitutes a brake element, a region for contact with a control element, which constitutes a switch, a region for guiding a fixing element, which constitutes a sliding element, and at least one point of application for engaging at least one fixing element which constitutes a spring element. In this preferred embodiment, the transmission element is a multifunctional element of the fixing mechanism in which the functions of guiding and braking the movement of the closure element, the application of a motive force to the closure element and the monitoring of the position of the closure element are combined in one element. Thus, the structure of the entire fixing mechanism and thus the extractor device simplifies.
According to the invention, the transmission element is preferably arranged so that it is located on the outside of a housing of the extractor device. The housing of the extractor device may be integrally formed.
According to a preferred embodiment, the housing of the extractor device is designed in several parts. In particular, the housing comprises as part of at least one main body of the fixing mechanism.
According to one embodiment, therefore, the fixing mechanism comprises a base body on which the transmission element is rotatably mounted. In particular, the shaft is guided through the base body, that is, perpendicular to the surface of the base body, which preferably has a cuboid shape. By the fixing mechanism having a base body, different functions can be integrated in the body and the rest of the housing of the extractor device may further have a simple structure, for example, consist of sheet metal parts. By contrast, the main body can consist of an aluminum block, for example, into which different contours have been milled. The main body in particular has an opening to the passage for the shaft, on which the closing body and the transmission element are arranged. The closing body is provided on one side of the base body and the transmission element on the opposite side base body on the shaft.
According to one embodiment, at least one fixing means and / or at least one control element may be provided at least partially on the base body of the fixing mechanism. For example, screws may be provided on the base body, to which the ends of spring elements which are opposite the ends with which they act on the transmission element are fastened. Furthermore, in the base body, for example, a groove can be introduced with a backdrop in which a lubricant, which is held movably on the transmission element, can be guided and can lock in the defined rotational positions of the closing element. In addition, a gear or another part of a brake element which can interact with the edge of the transmission element can be rotatably attached to the base body. Further, to the base body, for example, the switch for indicating the position of the closing element can be attached, which cooperates with the transmission element and is actuated by this.
By all these means or elements are attached to the base body or provided in this, the further structure of the fixing mechanism and the housing of the extractor device is simplified. In addition, the assembly and maintenance is simplified, since an alignment of a large number of items against each other can be omitted.
According to a preferred embodiment, a holder for holding the closing element is provided on the side of the main body, which is opposite to the transmission element, and the holder is connected to the transmission element on a common
Wave held. The side of the main body on which the transmission element is provided is also referred to below as the outer side. The opposite side of the body, that is, the inside, in the assembled state faces the interior of the housing of the extractor device. By a holder is provided on the inside of the base body, which is provided with the transmission element on a shaft, preferably rigidly, the force which is applied by the user to the closing element on the holder, the shaft and the transmission element on the other parts of the fixing mechanism, such as spring elements are transmitted. In addition, also caused for example by the spring elements movement force can be transmitted to the transmission element via the shaft and the holder to the closing element and this are thereby brought into a desired position. By providing a holder for holding the closing element on the shaft, the shaft can be designed simply and in particular requires no special geometry. Furthermore, the separate provision of a holder is advantageous because it can be made of a suitable material, such as plastic, which is different from the material of the shaft. Finally, by the separate configuration of the holder and an exchange of the holder can be done in a simple manner.
According to one embodiment, the holder has at least one latching arm for latching with an insertion opening of the closing element. This embodiment is advantageous, since thereby a secure hold of the closing element can be ensured during operation of the extractor device and yet for maintenance or cleaning purposes, the closing element can be removed from the holder.
According to another embodiment, at least one channel for a cable is incorporated in the base body. The channel may be provided on the inside of the main body. The cable which can be guided in this channel is preferably a cable for the switch, which may be provided on the fixing mechanism. By providing a channel in the base body, the cable can be guided safely and in particular a tearing of the cable can be prevented when moving the closing element and the transmission element. By providing the channel in the body of the fixing mechanism, the other structure of the housing of the fume extractor can be kept simple.
According to another embodiment, at least one passage opening for a locking pin for locking the transmission element is provided in the base body. The passage opening extends from the inside to the outside of the main body. Since the outer side of the base body, on which the transmission element is provided, is not accessible in the mounted state, when replacing, for example, the holder for the closing element, by unscrewing a movement of the transmission element can not be prevented. In order to be able to prevent such a movement or a rotation for maintenance work, a locking pin can be introduced from the inside into the passage opening. This protrudes into a receiving opening of the transmission element and thus prevents rotation of the transmission element. The receiving opening may for example be a gap or slot in which a sliding element of the fixing mechanism is guided in the transmission element. After maintenance, the locking pin can then be removed.
According to a preferred embodiment, a defined rotational position of the closing element is a blocking position, which is also referred to below as the rest position, rest position or blocking division, and another rotational position an operating position, which is also referred to below as the operating position or operating position, is in the locked position the suction port closed by the closing element. In this position, therefore, no air can enter the suction opening and thus into the extractor device. Also impurities can not enter the extractor device in this position. In the operating position, however, air can enter the extractor device via the intake opening, that is, air can be sucked in via the intake opening.
By these rotational positions are fixed by the fixing mechanism of the extractor device, a simple and reliable switching between these rotational positions can be done without that the user has to cumbersome set himself. This is advantageous since, when setting or searching for the suitable rotational position of the closing element for the individual states of the
Extractor device can come through the user that the orientation of the closing element to the suction port is not accurate. Thus, for example, when setting a rotational position in which the user assumes that the suction opening is closed, but that in fact is not completely closed, impurities can enter the suction opening. Even when setting a rotational position, which should correspond to the operating position, but must be found out by the user himself, there may be disadvantages. In particular, a higher fan power than necessary may be necessary if the suction port is still partially closed by the closing element. These disadvantages are not to be feared in the embodiment of the extractor device according to the invention, in which the operating position and the rest position of the closing element are predetermined. In addition, with this embodiment, the different states of the extractor device can be quickly adjusted. Furthermore, the closing element is fixed in the defined rotational positions. Thus, for example, by placing or placing objects on the closing element can not come to an unwanted movement of the closing element. By adjusting the defined rotational positions by actuation of the closing element, the construction of the extractor device is simplified.
Preferably, the closing element comprises an elongate closing body which has at least one blocking side which is impermeable to air, and at least one suction side which is at least partially permeable to air.
The sides of the closing body, which are also referred to as surfaces or areas, preferably define a space. The closing body can therefore also be referred to as a spatial closing body and represents a hollow body or a hollow profile, which can be made in one piece for example by bending a sheet. In this case, a body is referred to as a spatial closing body, through the sides of which a three-dimensional space is defined. Particularly preferably, at least two sides of the closing body define the three-dimensional space.
The closing body preferably has at least one blocking side and at least one suction side, which lie in each case parallel to the axis of rotation of the closing body and which together define the space of the closing body. Each of these sides of the closing body preferably has in projection on the suction opening, in which
Closing body is provided, a size corresponding to the size of the suction port.
As a blocking side is referred to in the context of the invention, the part of the closing body, which forms a continuous surface of luftundurchlässigem material. The blocking side is therefore also referred to below as a blocking surface. The suction side refers to the part of the closing body in which at least one opening suitable for the air inlet is provided, but the opening preferably covers a smaller area than the area of the suction opening. Particularly preferably, a plurality of openings are provided in the suction side, which are separated from each other, for example by webs.
Preferably, the suction side of the closing body is formed by a grid. As a grating in this case is referred to a material in which at least two openings are provided which are limited by struts or other pieces of material. For example, a grid in the context of the present invention may also be a perforated plate, wherein the openings in the perforated plate may have, for example, round or rectangular cross sections. By using a grid as the suction side, on the one hand, reliable suction of air via the suction side is ensured. On the other hand, but also the stability of the closing body and thus of the closing element against closing elements, in which the suction side is replaced by a through opening, increased. Finally, in the case of a vapor extraction device in which the suction side covers the intake opening in the operating position, it is advantageous if the suction side is designed as a grille, since this can prevent the falling of larger objects, such as parts of the food.
The at least one blocking side and the at least one suction side are preferably parallel to the axis of rotation of the closing body. In this case, the axis of rotation of the closing body is an axis about which the closing body can be rotated in the state mounted in the suction opening. The axis of rotation is in this case in the surface of the intake or preferably parallel thereto. In an elongate closing body, the axis of rotation extends in the longitudinal direction of the closing body.
By preferably at least one blocking side being provided on the closing body, the suction opening can be closed at least temporarily by this side of the closing body. However, since at least one suction side is additionally provided on the closing body, air can at least temporarily pass into the suction opening of the extractor device and can thus be sucked in by the extractor device. Preferably, the locking side and the suction side are parallel to the axis of rotation of the closing body. In this way, by turning the closing body about the axis of rotation optionally the blocking side or the suction side can be brought into a position in which it covers the suction opening of the extractor device or is located in this. The closing element does not have to be removed from the extractor device during this movement.
The position or position of the closing element and thus also of the closing body, in which the blocking side of the closing body lies in the suction opening, is also referred to as blocking position, blocking position, rest position or rest position. The position or position of the closing element and thus also of the closing body, in which the suction side of the closing body lies in the suction opening, is also referred to as the operating position or operating position. The blocking side of the closing body, which may also be referred to as a blocking region, and the suction side of the closing body, which may also be referred to as the suction region, are also referred to as functional regions or functional surfaces of the closing body.
If the closing body is formed exclusively by the blocking side and the suction side, at least part of the suction side serves for the passage of air into the extractor device in the mounted state of the closing body. Preferably, however, the closing body has at least one passage side in addition to the blocking side and the suction side. The passage side here is the part of the closing body, via which air can pass from the suction opening into the extractor device. The passage side is therefore preferably formed by an opening which forms the largest part of the passage side. This opening may be bounded by webs at the edges.
An advantage of providing a passage side, which is also referred to as a passage region, and which is formed essentially by a through-opening, is in particular that the air resistance can be minimized when flowing through the air by the closing body. The air resistance in this embodiment is therefore lower than in an embodiment in which, except for a blocking region, only one intake region, in which webs are preferably arranged, is provided. In addition, the passage region can also be used for introducing fastening elements, such as a shaft or axle, which are provided on the extractor device in the region of the suction opening.
According to a preferred embodiment, at least the area of the blocking side of the closing body in projection onto the suction opening corresponds to the area of the suction opening. In this way, a reliable closing of the intake opening can be ensured.
The cross section of the closing body can be round or polygonal. In a round cross section, the blocking side and the suction side are formed by curved surfaces. The axis of rotation of a closing element, whose closing body has a round cross-section, in this case preferably extends through the center of the cross section.
According to a preferred embodiment, however, the closing body has a triangular cross section, preferably a cross section of an equilateral triangle. In this embodiment, preferably one of the sides of the triangular shape forms the blocking side, one side the suction side and one side the passage side of the closing body. In this embodiment, the triangle sides can each represent or define planar surfaces. However, it is also possible in this embodiment that at least one of the triangle sides represents a curved surface. By the closing body has a triangular cross-section, the closing element in the rest position of the closing body in which the locking side is facing outwardly, cover the suction through a flat surface and thus can be flush with a provided for example around the suction port frame. By turning the closing element by 120 °, in a triangular, equilateral closing element, the suction side can be easily brought into the position in which it covers the suction opening of the extractor device and lies precisely in this position. In this operating position, air can thus enter the extractor device via the openings in the suction side. Since the blocking side to the suction side is at an angle of 120 ° with a closure member having a triangular, equilateral cross section, in the position in which the suction side covers the suction opening of the extractor device, the blocking side does not or only slightly prevents the suction of air into the extractor device , The blocking side can serve in the operating position of the closing body for Lüftführung in the flow direction behind the suction port.
The third side of the triangular cross section of the closing body preferably forms the passage side of the closing body. In this case, the passage side of the closing body can be completely open and limited at the edges only by one edge of the material of the blocking side and the material of the suction side. However, it is also possible that in particular to increase the stability of the closing body, the edges of the passage side are formed by flanges or webs of the material of the other two sides. These flanges or ridges can be created by bending over the material of the other sides.
An advantage of a triangular, preferably equilateral, shape of the cross section of the closing body is that the length of the legs of the cross section at the same time represents the largest dimension of the cross section. Upon rotation of the closing body about the axis of rotation, which is perpendicular to the cross-sectional area of the closing body, the maximum dimension, which lies in a plane at a distance from the axis of rotation, is always less than or equal to the length of one of the legs of the triangular cross-section. Thus, the closing body can be rotated in a suction opening whose width corresponds to the length of one of the legs of the triangular cross section of the closing body. In this case, the closing body does not abut against the edges of the suction opening and, in the positions in which one of the legs lies in the suction opening, still completely covers the suction opening. For a quadrangular cross-section of the closing body, for example, this is not possible since the diagonal represents a larger dimension than the side lengths of the quadrilateral.
Preferably, the closing element of the extractor device is configured such that the closing element comprises a closing body which has at least one blocking side and at least one suction side, each parallel to the axis of rotation of the
Schließköpers are and together define the space of the closing body, and that at least one part of a fastening device for a rotatable mounting of the closure element on the extractor device in the region of an intake opening of the extractor device is provided on at least one of the end sides of the closing element.
Preferably, at least one part of a fastening device for a rotatable attachment of the closing element to the extractor device is thus provided on at least one of the end faces of the closing element in the region of an intake opening of the extractor device. In this case, the sides of the closing element are designated as the front side, which define the space in the closing body together with the at least one blocking surface and the at least one suction side. In an elongated, that is, longitudinally extending, closing body, the end faces in the region of the end faces, that is, the longitudinal ends of the closing body are arranged. More preferably, the end faces are perpendicular to the suction side and the blocking side of the closing body. As a fastening device one or more means is referred to within the meaning of the invention, which can cooperate with the suction and / or other means provided thereon, in particular a holder on the shaft to a holder of the closing element on the extractor device in the region of the intake opening at least to effect temporarily. The fastening device preferably serves for the releasable attachment of the closing element to the extractor device, in particular in the region of the suction opening of the extractor device.
The at least one part of the fastening device, which is provided on the closing element, preferably lies in the axis of rotation of the closing element. The axis of rotation lies with the elongate closing element in the longitudinal direction of the closing element. In the mounted state of the closing element on the extractor device, the part of the fastening device is preferably downstream of the suction opening in the flow direction. In a Muldenlüftung the part of the fastening device is therefore in the mounted state below the suction port. The distance to the suction opening is dimensioned such that in at least one rotational position of the closing element, one side of the closing element lies in the surface of the suction opening.
The fastening of the closing element on the extractor device, according to the invention constitutes a rotatable attachment. Thus, the closing body of the closing element can be rotated about its axis of rotation in the suction opening, the fastening device is preferably in the axis of rotation of the closing body.
According to a preferred embodiment, at least a part of the fastening device of the closing element is an insertion device, which can also be referred to as a push-in device. In the context of the present invention, an insertion or insertion device is a device by means of which a connection between the closing element and the extractor device can be generated by translational movement of the closing element with respect to the suction opening. Thus, the closing element can be connected to the extractor device in the region of the intake opening by inserting the closing element from above into the intake opening.
According to a preferred embodiment, at least part of the fastening device of the closing element comprises at least one insertion opening. This can be provided as a gap or slot in the end face of the closing element and with the holder of the fixing mechanism, which projects from the inside of the main body of the fixing mechanism inwardly into the suction, engage. For fixing the closing element in the end position of the insertion opening, one or more locking elements may be provided. Preferably, the locking elements are locking lugs, which cooperate with latching arms of the holder.
An advantage of the provision of an insertion opening is that a simple introduction and removal of the closing element in the region of the suction opening on the extractor device, in particular by inserting into the suction is possible.
According to one embodiment, the end faces of the closing element are offset inwards relative to the longitudinal ends of the closing body. This offset creates a projection that can serve as a grip for the user. To the closing element, for example, for cleaning purposes or for access to
Filter elements which are arranged downstream of the closing element to be able to remove from the suction port, it is necessary that the user can hold the closing element. For this purpose, the handle created by said projection can serve. This embodiment has the advantage that on the outside of the closing element no separate handles or recesses must be provided. On the one hand, this improves the visual impression of the closing element in the different positions, in particular the operating position and the rest position. On the other hand, can be provided by the fact that no engagement openings must be provided on the locking side, a continuous surface and the openings in the suction side can be chosen smaller than would be necessary for engagement by means of the fingers.
Preferably, the fixing mechanism of the extractor device is a push-to-open mechanism. A push-to-open mechanism is understood to mean, in particular, a mechanism in which, by applying pressure to the closing element, the closing element is locked in a rotational position and released Fixation can be effected. For example, the push-to-open mechanism may constitute a mechanism in which a movement of the closing element, that is, a rotation of the closing element beyond this rotational position is required for fixing the closing element in a defined rotational position and the closing element then automatically, in particular by spring force is brought into the defined rotational position. To release the fixation from a defined rotational position is also a movement, that is a rotation of the closing element on the rotational position also required, the closing element is then automatically, in particular by spring force in a further defined rotational position is brought. This further defined rotational position can be, for example, the removal position. According to a preferred embodiment, the push-to-open mechanism comprises a link, along which a sliding element is guided away to a stop and from a stop. For at least the defined rotational positions of the locking position and the operating position in this case preferably a separate backdrop is provided with a catch. Between these two scenes, the sliding element is preferably guided in a guide elements, which may, for example, constitute an arcuate groove. The sliding element is preferably provided at one end of a transmission element, in particular in the form of a rigid lever, and extends perpendicular to the length of the lever. In a middle position of the sliding element between the two scenes, the two provided spring elements are relaxed. This position represents the removal position. In the operating position and the blocking position, however, one of the spring elements is tensioned in each case and thus ensures that the sliding element is held in the corresponding detent.
Preferably, the extractor device is a well ventilation device with at least one horizontal suction port. In a well ventilation, the air is sucked down through the suction opening, that is, the fan is arranged below the suction opening in the extractor device.
The advantages of the present invention can be used particularly well in hollow vents with a horizontally arranged intake opening, since the occurrence of contaminants, especially of liquids, is a particular problem there.

FIG. 1 shows an embodiment of the extractor device 1 according to the invention. In this embodiment, the extractor device 1 is a so-called tray ventilation or table ventilation. The suction opening 10 of the extractor device 1 is arranged in the illustrated embodiment between two cooking zones of a cooker 2 and is located in the work surface. From the suction port 10, the air is sucked down via a below the cooking surface plane fan (not shown) down. The suction opening 10 is surrounded by a frame 100. The frame 100 represents the upper end of a housing 103 (see FIG. 2) of the fume extraction device 1. A closing element 11 is arranged in the suction opening 10. In FIG. 1, only part of the closing body 115 can be seen from the closing element 11.
The structure of the embodiment of the closing element 11 is shown in more detail in Figures 3 and 4. As can be seen from these figures, the closing element 11 consists of an elongated closing body 115, which has a triangular cross-section. The closing body 115 is formed in particular by a bent sheet metal. The three sides of the closing body 115 each have a different configuration. One side of the closing body 115 is formed by a continuous piece of sheet metal. This side represents the blocking side 110 of the closing body 115. A second side of the closing body 115 is configured as a grid 1110 and forms the suction side 111 of the closing body 115. The grid 1110 is formed by inserting openings in the sheet metal of the closing body 115. Between these openings are webs. The third side of the triangular closing body 115 is largely open in the illustrated embodiment. Only at the lateral edges are webs of the suction side 111 and the blocking side 110 in the third side over. This third, open side is also referred to as the passage side 112 of the closing body 115.
The closing body 115 has an elongated shape, that is, extends in the direction perpendicular to the triangular cross-section in the length. In the region of the longitudinal ends of the closing body 115 end faces 113, 114 are provided. These are perpendicular to the sides of the closing body 115 and are offset in the illustrated embodiment to the longitudinal ends of the closing body 115 inwardly. In an end face 113, an insertion opening 1130 is shown. The insertion opening 1130 is formed in the illustrated embodiment as a slot. In the front side 113, opposite end face 114, an insertion opening 1140 is provided as part of the fastening device. This insertion opening 1140 also represents a slot which extends from the passage side 112 to the center of the end face 114 and at the edges of locking lugs are provided.
Through the three sides of the closing body 115, a space is defined in the closing body 115, that is, the closing body forms a hollow body. At the longitudinal ends of this space is bounded by the end faces 113 and 114.
The closing element 11 formed by the closing body 115 and the end faces 113, 114 can be introduced into the suction opening 10 of a fume extraction device 1. As shown in Figure 5, in the housing 103 of the extractor device 1 at one of the longitudinal ends in the region of the suction opening 10, a shaft 101 is provided which extends horizontally into the interior of the housing 103. On the shaft 101, a holder 39 is attached, which has an upwardly tapering shape and has on the two sides in each case a latching arm 390. The latching arms 390 extend downwards, that is, their free ends are directed downwards. At the opposite longitudinal end of the housing 103 in the region of the suction opening 10, an axis (not shown) is provided which also extends into the interior of the housing 103. The shaft and the shaft 101 are offset to the top of the housing 103, on which the frame 100 is provided, which surrounds the suction port 10, down. The amount by which the axis and the shaft 101 are offset down to the top of the frame 100 in the illustrated embodiment corresponds to the smallest distance between the upper end of the
Insertion opening 1130 or the insertion opening 1140 and the outer surface of the locking side 110 or the suction side 111 of the closing element 11th
To insert the closing element 11, this is introduced with the passage side 112 down and with the end face 113 forward into the intake opening 10 and the holder 39 is inserted on the shaft 101 in the insertion opening 1140. Subsequently or simultaneously, the opposite end of the closing element 11 is lowered. As a result, the insertion opening 1130 engages with the axis and the axis can slide upwards in the slot forming this insertion opening 1130. As soon as the axis has reached the upper end of the insertion opening 1130 and the upper side of the holder 39 reaches the upper end of the insertion opening 1140, the closing element 11 is held in the extractor device 1 and in particular in the region of the suction opening 10. This position, which is shown in Figure 1 and in which the passage side 112 of the closing element 11 is directed downward, is also referred to as the removal position. In this position, the upper part of the roof, which is formed by the locking side 110 and the suction side 111, projects beyond the suction opening 10 and in particular over the frame 100 upwards. The user can engage in this area in the longitudinal ends of the closing body 115, that is, in the formed between the longitudinal ends and the end faces 113 and 114 protrusions of the closing body 115 and remove the closing element 11 by opposing movements to the just described movements of the extractor device 1 ,
If the extractor device 1 is to be used, the user can rotate the closing element 11 about the axis of rotation passing through the shaft 101. For this purpose, the closing element 11 is rotated counterclockwise from the removal position of Figure 1 until the suction side 111 of the closing body 115 is directed upward. This position is also referred to as the operating position. Due to the triangular cross-section of the closing body 115, the outside of the suction side 111 in this position is flush with the top of the frame 100. However, it is also possible that the outside of the suction side 111 is offset slightly downwards relative to the top of the frame 100. In the operating position, the blocking side 110 of the closing body 115 protrudes at an angle, in particular 120 °, down into the housing 103 below the suction opening 10. As a result, the air which is sucked into the housing 103 via the blower (not shown) directed after passing through the suction side 111 and passes through the passage side 112 of the closing body 115 in the housing 103 and to the fan. If the extractor device 1 is not used, the user can bring the closing element 11 in the rest position. In this rest position, the blocking side 110 of the closing body 115 is directed upward. In order to bring the closure member 115 and thus the closure element 11 from the operating position to the rest position, the user turns in the illustrated embodiment, the closing element 11 by 120 ° clockwise. The blocking side 110 of the closing body 115 completely closes the suction opening 10 in the rest position. As a result, the penetration of contaminants, in particular in the form of liquids, can be reliably prevented.
The setting of the different positions of the closing element 11, in particular the turning of the closing element 11, is preferably carried out manually by exerting a compressive force on one of the sides of the closing element 11. For this purpose, a fixing mechanism 3 is provided according to the invention. An embodiment of such a fixing mechanism 3 is shown schematically in Figures 2, 5, 6 and 7.
The fixing mechanism 3 comprises in the illustrated embodiment a transmission element 30 in the form of an elongate pendulum which is rigidly connected to the shaft 101. The shaft is formed by a screw which connects the transmission element 30 to the holder 39. For this purpose, the transmission element 30 has a passage in the upper region. The area around the passage is semicircular and has at the outer edge of a toothing in the form of a partial gear 351. The partial gear 351 covers 180 ° of the circumference of the semicircular end of the transmission element 30. The semicircle is pivoted in the removal position of the transmission element 30 shown in Figure 6 to the vertical to the right. This makes it possible to attach the gear 350, which forms the further part of the brake element 35 offset to the right to the transfer element 30 at a height to the base body 300, which is slightly higher than the height in which the passage for the shaft 101 in the Transmission element 30 is provided. from the semicircular area, the transmission element 30 extends downwards and its width increases downwards. At the bottom of a receiving opening 38 is provided in the form of a vertically extending slot in the removal position.
Between the passage for the shaft and the upper end of the receiving opening 38, two screws are provided as attacking devices 340 on the transmission element 30 in the illustrated embodiment. Preferably, the engagement devices 340 extend beyond the transfer element 30 only to one side.
At the engagement devices 340, the upper ends of fixing means in the form of spring elements 34 can be attached. The spring elements 34 may be present in particular in the form of spiral tension springs. The other ends of the spring elements 34 are attached to the base body 300 of the fixing mechanism 3 offset down.
The main body 300 represents a cuboid which can be connected to the housing 103, in particular screwed into an end wall of the housing 103 of the extractor device. In the outside of the main body 300, which is shown in Figure 2 and Figure 6, a guide member 31 is introduced in the form of an arcuate groove or double heart curve. In the guide member 31 is provided at its two ends in each case a link 32 as a fixing. Each link 32 has at its top a latch 320. In the guide element, a sliding element 33 is guided as a further fixing means. The sliding element 33 can be guided in the guide element 31 around the link 32 around. The other end of the slider 33, which identifies the shape of a pin, engages in the receiving opening 38 of the transmission element 30 and is guided there.
Furthermore, a recess for receiving the gear 350 of the brake element 35 is provided in the outer side of the base body 300. At the left in Figure 6 edge of the base body 300, a recess for receiving a switch 36 is introduced. The switching element of the switch 36 protrudes beyond the outside of the main body 300 in this case. If the transmission element 30 is now rotated clockwise from the removal position shown in FIG. If the left portion of the transmission element 30 at the back with the switching element of the switch 36 in contact and thus actuates the switch 36. The switch 36 is positioned so that the switch 36 is actuated over several degrees about the rest position, thus indicating that the Suction port is closed by the casting element 11.
In the rest or locking position of the closing element 11 of Figure 1, the slider 33 is engaged in the latch 320 of the left gate 32 and is held by the right spring element 34 in this position.
In order to move the closing element 11 out of this position, the user can exert pressure on the right outer longitudinal edge of the blocking side 110 of the closing body 115. This force is transmitted via the shaft 101 to the transmission element 30 and moves it in a clockwise direction. As a result, the sliding member 33 runs along the link 32 and comes out of engagement with the catch 320. By a projection in the guide member 31, which points above the link 32 in the direction of the link 32, the sliding member 33 to the top of the link 32nd directed. When the pressure on the blocking side 110 of the closing body 115 is removed, the sliding element 33, due to the spring force exerted on it by the right-hand spring element 34, runs along the upper side of the link 32 in the direction of the center of the guiding element 31 of the sliding element 33, the closing element 11 is also rotated via the transmission element 30. Once the right spring element 34 is relaxed, the closing body 115 is in the removal position shown in Figure 6. The spring elements 34 are both relaxed in this rotational position of the closing element 11.
From the removal position, the closing element 11 can be brought into the operating position. For this purpose, the user exerts a leftward pressure force on the upper edge of the suction side 111 of the closing element. As a result, the sliding element 33 is guided in the guide element 31 in the direction of the right-hand link 32 via the transmission element 30. With sufficient pressure, the sliding element 33 comes into engagement with the catch 320 on the link 32 and the closing element 11 is fixed in the operating position shown in FIG. In particular, the sliding element 33 is held in this position by the left spring element 34 in the latch 320.
The rotation of the closing element 11 and thus the movement of the sliding element 33 in the illustrated embodiment by the braking element 35 damped.
FIG. 7 shows the inside of the main body 300 of the fixing mechanism 3. On the inside of the holder 39 is fixed to the shaft 101. Behind the holder 39 extends in the inside of a channel 301, in which a cable can be guided to the switch 36. Furthermore, in FIG. 7, a locking pin 37 introduced into the passage 300 in the base body 300 is shown. The inside of the main body 300 is preferably covered by a cover 303, as shown in Figure 5, before the holder 39 is attached.
The invention is not limited to the illustrated embodiments.
The present invention has a number of advantages. In particular, can be dispensed with separate controls, such as buttons. In addition, an electric drive and the associated components are not required. Instead, the invention provides a purely mechanical closing element, which is simple and reliable to use and results in a flat surface both in the closed state, that is in the locked position, as well as in the open state, that is in the operating position. Thus, no protruding elements hinder cooking on the surrounding hob.
In addition, in the fixing mechanism according to the invention, in which a plurality of functions is provided on the transmission element, the space required for the fixing mechanism is small. In particular, the fixing mechanism has a low height. Finally, the fixing mechanism can be manufactured with great accuracy, since the base body can consist of an aluminum block in which grooves and depressions are milled in and the further functions are carried out on the transmission element. This reduces the required tolerance and the number of components. With the present invention, a push-to-open mechanism can be integrated in a limited volume.
