    Description
    Title of the invention: Air outlet for directing an air flow in different directions in a vehicle interior The present invention relates to the field of an air outlet. Specifically, the subject of the present patent application relates to an air outlet for a vehicle interior, which air outlet uses a movable air guide element inside a housing to guide the flow. of air from an inlet to an outlet, while allowing the air flow to be directed in different vertical directions.
    In most air outlets, the vertical direction of the air flow can be changed using shutters or slats in one of these two ways. In the first way, an air vent includes two separate slat blocks or channels. The air flow in a particular channel can be limited by adjusting the lamella (or blade) of this channel. Document EP 3063026B1 describes this mechanism for the vertical adjustment of the air flow.
    [0003] As a variant, the second way in which the current air vents allow the change of direction of air flow consists in using two air guide surfaces inside the air intake housing, adjacent to the opposite walls of the housing respectively. The two air guide surfaces divide the air outlet housing into three air channels. The first channel is between the first air guide surface and the first housing wall, the second is between the second air guide surface and the second housing wall, and the third air channel is between the two air guide surfaces. The blades are arranged at the end of each of the air guide surfaces, with the aid of each of which, each of the air channels can be closed. Document US 2014357178 describes the above mechanism for changing the direction of the air flow vertically.
    The problem with the first approach is that to change the direction of the air flow, part of the air flow that could otherwise flow through the air vent is reduced. For example, when the first channel is closed and the second channel is open, the total cross-section for the air flow inside the vehicle is only half the total cross-section of the air outlet. In particular, the resistance to flow increases considerably by closing one of the channels. As a result, the second channel can lead to only a reduced amount of air, for example only half of the total air flow which could otherwise flow through the air outlet. Thus, when changing vertical direction, the total volume of air flow is not maximum.
    The second approach, with a central body inside the air vent, solves the above problem but poses another problem. When the first or second channel is closed, the other channel and the central body receive 100% of the air volume. This increases the noise of the air flow when the same amount of air flows through a small area. In other words, the same volume of air that passes through the air vent when all the channels are open, passes through a reduced area when a channel is closed, thus increasing the noise of the air flow.
    [0006] Thus, the basic problem is to propose an air outlet which makes it possible to change the vertical direction of the air flow on several channels, while maintaining the maximum air flow and the constant noise level.
    The subject of this patent application provides a solution to this problem. The main objective of the subject of the present application is an air outlet which allows the flow of air from an air inlet to an air outlet, while maintaining the maximum air volume in all directions with a constant noise level. A hollow air guide element inside the air outlet housing guides a partial air flow from the first opening near the air inlet to the second opening near the outlet air. The presence of an air guide element creates three channels inside the air outlet. One above the air guide element, one through it and one below it. The channels above and below the air guide element need not be closed using closure elements, for example blades, as described in the prior art. In the present application, the air guide element is movable so that it can move between the first wall segment of the air vent housing and a second opposite wall segment of the housing. In this way, the channels can be closed or partially closed while keeping the maximum air flow through the air outlet and the noise level constant, since the total area through which the air passes. flow does not change and the number of flow obstruction elements is reduced. Specifically, this object is satisfied by the subject of independent claims 1 and 10.
    The air outlet which is the subject of this patent application is an air outlet comprising: a housing for guiding an air flow inside the housing of an inlet housing opening air to an air outlet housing opening; a hollow air guide element arranged inside the housing for guiding a partial air flow inside the air guide element from a first air guide element opening up to 'to a second air guide element opening. In addition, the air guide element is movable and can move in the direction from a first wall segment of the housing to a second opposite wall segment. The first wall segment of the housing can be opposite the upper side of the air guide element and the second wall segment of the housing can be opposite the lower side of the air guide element. In a first extreme position, the air guide element can abut against the first wall segment of the housing, while in a second extreme position, the air guide element can come into abutment against the second housing wall segment. The device is constructed so that when the air guide element is against the first housing wall, the air flow is in a vertical direction, for example upwards, and when the air guide element air is against the second wall, the air flow is in the opposite vertical direction, for example downwards. Up or down means that the air flow has an ascending or a descending component, respectively. Usually the air flow also has a horizontal component away from the air outlet. This design provides two distinct advantages. First, since the air guide element is hollow, the air passing through the air intake housing is maximum in each direction of air flow. Secondly, when changing the direction of the air flow, i.e. when moving the air guide member in different directions, the cross section of the total air flow remains almost the same the same.
    Another example is in the form of the air outlet comprising three channels for the air flow. This first channel is formed between the air guide element and the first wall segment of the housing, the second channel is inside the air guide element while the third channel is formed between the air guide element and the second wall segment of the housing. The size of the second channel (inside the air guide element), more particularly its cross section perpendicular to the direction of air flow inside the air guide element, is independent of the position of the air guide element relative to the housing. However, the size of the first and third channels changes by changing the position of the air guide member relative to the housing. So the cross section of the two channels perpendicular to the direction of air flow in the respective channel depends on the position of the air guide element. If the air guide element is moved towards the first wall segment of the housing, then the size of the first channel, in particular of its cross section, decreases and the size of the third channel, in particular of its cross section, increases . Similarly, the size of the third channel, in particular of its cross section, decreases and the size of the first channel, in particular of its cross section, increases, when the air guide element is moved in the direction of the second housing wall segment.
    Another example is in the form of the air vent according to any of the previous examples, where the first segment of the housing wall and the second segment of the housing wall are curved. Also, a first wall segment of the air guide member and a second wall segment of the air guide member are curved. More particularly, the first wall segment of the housing and the first wall segment of the air guide element form the first channel and the second wall segment of the housing and the second wall segment of the air guide element d form the third channel. The wall segments are curved so that the direction of the air flow from the first channel and the direction of the air from the third channel intersect. In use, the two air flows from the two channels collide with the air flow from the second channel. This feature makes it easier to change the direction of air flow.
    Another example is in the form of the air vent according to any of the previous examples, where the housing further comprises a control element. The control element is used to control the movement of the air guide element, so that the air flow can be directed up or down. It is through the control element that the vehicle occupant can change the direction of the air flow.
    Another example is in the form of the air outlet according to any one of the preceding examples, in which the air guide element comprises at least one pivoting vertical blade arranged inside the air guide element for directing the second partial air flow to the left or to the right inside the vehicle. To the left or to the right means that the air flow has a left component or a right component, respectively. Usually the air flow also has a horizontal component away from the air outlet. In one embodiment, several vertical blades are mechanically connected together so that all of the vertical blades rotate simultaneously. In such an embodiment, a simple control element can be used to direct the air flow both in the upward or downward direction and in a direction to the left or to the right. The vertical blades can rotate about an axis which is essentially vertical, but which axis can deviate slightly from the vertical direction when the air guide element is moved.
    Another example is in the form of the air outlet according to any one of the preceding examples, in which when the control element is moved in the upward direction, the air guide element moves up to the first wall segment of the housing. As the air guide element moves upwards, the size of the channel between the air guide element and the second wall segment of the housing, the third channel, is increased. Increasing the cross section of the third channel results in increased air flow through this third channel. On the contrary, the size of the channel between the air guide element and the first wall segment of the housing, the first channel, decreases. Reducing the cross section of the first channel results in a reduction in the air flow through this third channel. In the case in which the movement of the air guide element is only a translational movement without rotation component, then the direction of the air flow in the second channel does not change and the resulting air flow at the interior of the vehicle, away from the air outlet, is directed more upwards.
    When the control element is moved in the downward direction, the air guide element moves down towards the second wall segment of the housing, thus increasing the size of the first channel between the element air guide and the first segment of the housing wall, the first channel. Increasing the cross section of the first channel results in increased air flow through this first channel. On the contrary, the size of the channel between the air guide element and the second wall, the third channel, decreases. Reducing the cross section of the third channel results in a decrease in the air flow through this third channel. In the case in which the displacement of the air guide element is only a translational movement without rotating component, then the direction of the air flow of the second channel does not change and the resulting air flow remotely of the air vent inside the vehicle is directed further down.
    Another example is in the form of the air outlet according to any one of the preceding examples, in which the air guide element also rotates upwards and downwards, while rising and going down respectively. Rotating the air guide element changes the vertical direction of the air flow from the second air channel. An advantage of such rotation is that the air flow from the air outlet inside the vehicle can be directed more up or down by rotating the second channel upwards or down. The rotation of the air guide element can for example move the second air guide element opening downwards and the first air guide element opening upwards so that the second flow partial air is directed in a downward direction. Rotation of the air guide member can also move the second air guide member opening up and the first air guide member opening down so that the second flow of air partial air is directed in a downward direction.
    In another example of an air outlet comprising a rotary air guide element, the axis of rotation is located on the side of the air inlet of the air guide element. An advantage of this embodiment lies in the fact that following the downward movement of the control element, two effects are combined to improve the downward directivity of the air flow inside the vehicle. First, moving the control element down increases the cross section of the first channel, which increase results in an increase in the first partial downward directed air flow. Second, moving the control element down also directs the second partial air flow further down. Similarly, moving the control element upwards combines two effects to improve the upward directivity of the air flow inside the vehicle. First, moving the control element up increases the cross-section of the third channel, which increase results in an increase in the third partial air flow directed upwards. Secondly, moving the control element upwards also directs the second partial air flow further upwards.
    Another example is in the form of the air vent according to any one of the preceding examples, in which the first channel can be closed by compressing the air guide element completely against the first segment of wall of the housing to prevent a downward flow of air from the first channel.
    Another example is in the form of the air outlet according to any one of the preceding examples, in which the third channel can be closed by compressing the air guide element against the second wall segment of the housing to prevent the upward flow of air from the third channel.
    Another example relates to a method, when it is preferably applied to an air outlet according to any one of the preceding examples, according to which the air flow can be modified in different directions while maintaining the constant or almost constant total air flow volume. This can be achieved by moving the air guide element up or down and by pivoting at least one blade arranged inside the air guide element around a vertical axis to direct partial air flow in a left or right direction.

    While the disclosure is likely to undergo different modifications and alternative forms, its specific features have been presented by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the aspects of the disclosure to the particular illustrative embodiments described. Rather, the intent is to cover all of the modifications, equivalents, and variations within the spirit and scope of the disclosure.
    Figures 1 to 3 and 4 to 6 show the front and perspective view of the air outlet, as visible by an end user, respectively. As shown in these figures, the end user, for example a vehicle occupant, is provided with a control element 14, projecting towards the front of the air outlet. The control element is mechanically fixed to the air guide element so that the movement of the control element results in a corresponding movement of the air guide element. With the control panel, a vehicle occupant can change the direction of the air flow from the air outlet. In FIGS. 3 and 6, the control element is in the central position so that the air flow is in an axial direction relative to the air outlet. In FIGS. 1 and 4, the control element and therefore also the air guide element are in the upward position, thereby directing the air flow upwards. In FIGS. 2 and 5, the air flow is directed downwards when the control element and the air guide element are in the downward position. In FIGS. 3 and 6, the control element and the air guiding element are in a central or neutral position, resulting in a horizontal air flow inside the vehicle.
    In Figures 1 to 3 and 4 to 6, one can also observe vertical blades. These vertical blades can be rotated left and right to direct the second partial air flow in the left or right direction. In the central or neutral position of the air guide element, the vertical blade can pivot around an axis of rotation of the blade which is vertical. When the air guide element is rotated in another position about a horizontal axis, the axis of rotation of the blades rotates accordingly because the blades are pivotally attached to the guide element d 'air. In Figures 1 to 3 and 4 to 6, the vertical blades are in a neutral or central position. The control element can be moved in the right direction to direct the second partial air flow in the right direction and the control element can be moved in the left direction to direct the second partial air flow in the direction left direction.
    Figures 7, 8 and 9 illustrate the internal view of the air vent, not visible to the end user, for example a vehicle occupant. The three figures show a housing 1 which has an air inlet housing opening 2 and an air outlet housing opening 3. The housing also has a first wall segment 7 and a second wall segment 8. As can be seen, the wall segments of the housing are curved towards each other at the air outlet opening, so that the first wall segment 7 is oriented downwards while the second wall segment 8 is oriented upwards.
    Inside the housing, there is an air guide element 4 which guides a partial air flow between its first opening 5 and its second opening 6. The first opening 5 of the guide element d air is aligned with the air inlet 2 of the housing, while the second opening 6 of the air guide element is aligned with the air outlet opening 3 of the housing. Furthermore, it can also be seen that the air guide element has two wall segments 9 and 10 which are curved to the same degree as the housing wall segments 7 and 8 respectively.
    In Figure 9, when the control element 14 and the air guide element 4 are in the neutral position, the air guide element is in the central position in the housing. We can observe three channels. The first air channel 11 is between the air guide element and the first wall segment 7 of the housing. The second air channel 12 is formed inside the air guide element. And the third air channel 13 is formed between the air guide element and the second wall segment 8 of the housing. The total cross section through which the air flows through the air outlet is given by adding the cross sections 16, 17 and 18. The cross section for the air flow inside the element air guide is represented by 18. Typically, the cross section of channel 2, therefore the channel inside the air guide element, can be equal to or less than the joint cross sections of the first and third channels .
    In Figure 8, when the end user has pushed the control element in the downward direction, the air guide element also moves and rotates downward. However, in another embodiment, there can be only a translational movement in which the air guide element, from the neutral position, as shown in Figure 9, is moved down without rotation. In this case, the second partial air flow is always directed horizontally, but due to the collision with the first partial air flow directed downwards, the resulting air flow inside the vehicle is directed towards the bottom.
    Similarly in Figure 7, when the end user pushes the control element in the upward direction, the air guide element moves and rotates upwards. However, as already mentioned above, in another embodiment, there can only be a translational movement in which the air guiding element, from the neutral position, as indicated in FIG. 9 , is moved up without rotation. In this case, the second partial air flow is always directed horizontally, but due to the collision with the third partial air flow directed upwards, the resulting air flow inside the vehicle is directed towards the top.
    In Figure 10, a blade or vertical strip 15 is shown, and also the part of the air flow 19 that the strip affects. The vertical blade allows the direction of the air flow to be changed horizontally. Placing the blade inside the air guide element does not increase the height of the air vent.
    Figures 11, 12 and 13 illustrate a rotational movement of the air guide element. More particularly, these figures represent an axis of rotation which is located on the side of the air inlet of the air guide element. To allow this rotational movement, the air guide member includes an extension in the direction of the air inlet opening of the housing. This extension can be inside the housing, but preferably the extension is arranged outside the housing. More specifically, there may be two extensions, one on the left side of the housing and one on the right side of the housing, when looking at the air outlet from the side of the air outlet.
    In the figures, only the embodiments of an air outlet with a control element for the manual control of the air outlet are shown. In the other embodiments of the invention, the movement of the air guide element is controlled by a motor. The same applies to the displacement of the vertical blades. Motorized movements are preferably carried out by one or two motors which are arranged outside the housing, more particularly outside the channels. The motors can be arranged on the left or right of the housing and can be mechanically coupled with the air guide element and the vertical blades.
