    OVEN OR STOVE DRAWER ELEMENT AND KITCHEN EQUIPMENT STATE OF THE ART
    In kitchen equipment, especially in kitchen appliances such as an oven or an electric oven, guide devices for guiding a pusher element of the kitchen appliance are known. The guide devices for the kitchen equipment must meet complex requirements and be made compact, reliable and easy to use. The guides in ovens or stoves must also be heat resistant.
    OBJECT AND ADVANTAGES OF THE INVENTION
    Object of the present invention is to provide initially mentioned arrangements and kitchen equipment technically and economically advantageous, in particular with regard to a reliable and easy to use version.
    This object is solved by the independent claims.
    The dependent claims show advantageous developments of the invention.
    The invention is based on a stove or stove push element drive for guiding the movement of a pusher element of a kitchen appliance such as a baking oven or an electric range, wherein the pusher element is attachable by means of the pusher element drive on a side wall of the kitchen appliance, and wherein the pusher element drive one of the side wall assignable Inner rail and a slidably received on the sliding element drive sliding rail includes, and a motor drive unit for the driven movement of the displaceable rail and cooperating with the drive unit control unit for controlling the drive unit.
    In so-called full extension with a fixed position inner rail, a middle rail and a pull-out rail, the thrust element is added to the pull-out rail. Between the fixed rail and the middle rail and between the middle rail and the pull-out rail load-transferring bearing means for movable mounting of the rails are present to each other. With the bearing means a noise and low-friction linear displacement movement of the middle and the extension rail over the entire Ausziehweg or over the entire movement distance is made possible, which can be bridged with the full extension in both displacement directions.
    With partial excerpts starting from the fully inserted in the kitchen utensil state of the thrust element is possible compared to a full extension lesser Ausziehweg of the thrust element, wherein a middle rail is missing and the drawer rail is slidably disposed on the inner rail via load-bearing bearing means.
    A first aspect of the invention is that there is an elongated flexible pull-push element which is movable by the drive unit for movement of the push element, the pull-push element being coupled to the sliding rail of the push element drive. This advantageously improves the use of kitchen appliances such as a baking oven or an electric cooker.
    The train-pressure element can with the sliding rail directly, as in a partial extract, or via an intermediate part, such as. B. a middle rail of the full extension, be indirectly coupled. In the case of the full extension, the pull-push element preferably engages the center rail.
    With the train-pressure element, a particularly space-saving and practical motorized movement of the pusher element is realized.
    The flexible tension-pressure element is not only thermally and mechanically sturdy ready to be deployed comparatively slender without problems and in spatially difficult or cramped conditions advantageous over other arrangements used. In addition, a train-pressure element is robust against high temperatures or tolerant of frequent temperature changes, whereby the train-pressure element is particularly advantageous replaceable in ovens and electric stoves, where the train-pressure element from ambient temperature during operation of the kitchen appliance regularly and continuing to high temperatures z. B. heated by several hundred degrees Celsius or is exposed to this.
    The oven or stove push element drive is designed in particular as a partial or full extension with motor drive.
    Preferably, the oven or stove push element drive according to the invention comprises two cooperating full extensions for a common push element or two cooperating partial extracts, wherein both sliding rails are driven by a common drive unit. The two full or partial extracts are recorded at the same horizontal height on opposite vertical side wall insides in a heatable receiving volume such as a baking muffle of the kitchen appliance. The associated push element can be placed with its two side edges on the respective sliding rails of the full or partial extracts.
    With the proposed drive also measures and dangers in the use of ovens or electric stoves are avoided or minimized. In the case of non-motor-driven pusher elements, it is disadvantageous that a pusher element such as a baking tray or a support grid has to be pushed in or pulled out manually by heating in the kitchen appliance in the hot state. In order to remove the hot baking tray or support grid, the user must take protective measures against burns or possible accident hazards. For example, potholders or protective gloves must be used to grip the baking sheet.
    Such additional measures and accident hazards are inventively avoided particularly advantageous.
    The oven or stove push element drive with the drive unit is preferably integrated in the kitchen appliance available, in particular accommodated on or inside the kitchen appliance, for example, covered by a housing portion of the kitchen appliance outside. The drive unit is preferably positioned outside the externally insulated, heated interior volume of the kitchen appliance or outside the baking chamber.
    With the positioning of the drive unit outside the baking muffle, the drive unit is indeed positioned in the immediate vicinity of the baking muffle but thermally separated from the heated baking muffle, which allows a comparatively short length of the train-pressure element and advantageously increases the life of the drive unit.
    In particular, the drive unit comprises a motor, in particular an electric motor, preferably for example a geared motor.
    The flexible tension-pressure element is preferably designed so that it remains at a pressure applied by itself in its elongated initial basic shape without laterally bending or evading. Nevertheless, an almost arbitrary spatial orientation of the tension-pressure element, for example, with guidance means can be deliberately specified. In the pressure load, the tension-pressure element is therefore variable in its spatial orientation, in particular by the guide means. The tension-pressure element can be spatially changed or bent by an angle in the pressure load, for example, from a linear or straight alignment at a predetermined location in the kitchen appliance. The bend can be, for example, about 90 degrees. The transfer of compressive forces by the train-pressure element or along the train-pressure element is advantageous not only linear possible despite the bend. The tension-pressure element behaves in the respective spatially differently oriented straight sections as a rigid element, which passes on the bend a compressive force or pressure effect in the subsequent direction of action straight section.
    The spatial orientation of the train-pressure element is preferably vor-gebbar by externally on the train-pressure element coming into abutment guide portions of guide means. The fitting to the train-pressure element guide portions are, for example, rigid sections, preferably with changing orientation in particular z. B. with a curved contour extending to rest on the train-pressure element.
    The sliding rail or the pull-out rail of the partial extension or the middle rail of the full extension, is preferably connected to an end portion of the train-pressure element and can be pushed out with the push-pull element from the kitchen appliance.
    For the retraction or retraction of the pushed sliding rail, the train-pressure element is preferably claimed to train. For this purpose, the tension-pressure element can have a spatial orientation corresponding to the spatial orientation when moving out the displaceable rail, which has one bend or several bends. Preferably, the tension-pressure element has exactly one bend by about 90 degrees, wherein the tension-pressure element in the region of the bend is not bent at an angle but according to a radius. It is also possible that the tension-compression element in the area of a bearing is wound up and unwound.
    The drive unit is used for the driven movement and positioning of the displaceable rail, whereby the connectable to the sliding rail push element on the kitchen appliance is movable and positionable.
    Positioning is carried out, for example, with a position detection, with the help of which the pusher element at any or possible shift point is haltable by the drive is turned off or the drive unit is turned off.
    Another essential aspect of the invention is that the motor drive unit comprises a spindle drive arrangement. A spindle drive arrangement can be produced particularly economically, in particular from many differently standardized components available such as threaded spindles and associated spindle nuts. The spindle drive arrangement preferably has a spindle with an external thread and an associated matching internally threaded nut or a driver. The spindle engages through the nut or the driver, wherein the thread of the spindle and the thread of the nut or the thread of the driver mesh with each other. By a rotation of the fixed spindle, the mother or the driver is moved linearly, wherein the nut or the driver is firmly connected to the middle rail of the full extension or with the pull-out rail of the partial extension. As a result, in the case of a full extension, the middle rail of the full extension or, in the case of a partial extension, the pull-out rail is driven by the spindle depending on the direction of rotation of the spindle in the ejection direction or feed direction. With the middle rail of the full extension, the pull-out rail can be moved, which is done in particular with a load transfer arrangement.
    With the spindle drive assembly of the drive unit so that the movable rail and thus the thrust element driven to move and position. The spindle operating arrangement is advantageously mechanically robust and enables precise and stepless adjustment of the displaceable rail.
    The rotatable about its longitudinal axis of the drive unit in both directions of rotation spindle is stored, for example, on the one hand to a support on the inner rail of the full extension or on the inner rail of the partial extension and on the other hand outside of the insulated interior of the kitchen appliance. The spindle is thus mechanically stable over at least two mutually remote bearings.
    The center rail of the full extension is preferably by means of a nut or a
    Driver along the spindle, depending on the direction of rotation of the spindle, pushed out of the interior of the kitchen appliance to the outside or pulled into this again. The spindle bridges the length from the bearing point outside the insulated interior to the nut or to the driver. The spindle has a minimum length, which is derived from the distance between the bearing outside of the insulated interior to the point, which occupies the mother or the driver at maximum pushed-out center rail.
    With the linear movement of the middle rail, the pull-out rail is moved, preferably by a translation or load transfer, which includes, for example, a cable arrangement. The load transfer is preferably tuned so that the pull-out rail is displaced by a distance corresponding to twice the distance covered by the center rail.
    In partial excerpts the pull-out rail is driven directly by means of the nut or the driver on the pull-out rail.
    In a motor drive of two belonging to a thrust element partial or full extensions discs are present on the two spindles of the two extracts outside of the insulated baking muffle. These provide a drive connection to the particular common drive unit.
    The drive unit such. As a geared motor is optionally equipped with a drive pulley, whereby the drive unit are drivingly connected to the spindle by a load transfer element which acts between the drive pulley and the disc on the spindle. The load transfer element may comprise, for example, a toothed belt, a rope or a chain or the like.
    Further, it is advantageously such that operating means are provided, which can be acted upon from outside with an operating operation on the control unit, wherein the displaceable rail can be brought into a predeterminable position. With the sliding rail, the thrust element is driven driven in a desired position. When mounted on the kitchen appliance inventive drive the pusher is moved after a control command with the operating means in particular from the fully retracted inside position in the fully pushed out of the interior position and back again. For this purpose, of course, a front door of the kitchen appliance must be open. With the invention, the push element is user-friendly accessible and re-inserted. The optionally hot pushing element advantageously does not have to be moved by hand.
    The operating means preferably comprise a manually operable switching unit, in particular on a front side of the kitchen appliance, wherein the switching unit cooperates with the control unit or is connected.
    Alternatively or additionally, the operating means may have a remote from the kitchen appliance remote control.
    It is further proposed that according to an advantageous variant of the invention, the train-pressure element has an elongated inner part and an outer part guided around the inner part around. The inner part may for example be a solid body or one of a plurality of individual elongated flexible parts. As the inner part, for example, a thin steel cord of a plurality of individual steel wires is preferably used. The inner part may alternatively consist of another material, for example made of plastic.
    The outer part is preferably also a thin flexible elongate element, for example a metal wire or a plastic element. The outer part may consist of a continuous piece and be wrapped around the inner part over its entire longitudinal extent, for example helically or helically. The outer part may alternatively consist of several individual parts, which are each wrapped around the inner part, for. B. annular transverse or oblique to the longitudinal axis of the inner part.
    [0038] The outer part preferably forms a contouring or profiling on the outer side of the
    Pressure element, for example, is increased to the outside of the inner part, which preferably even on the outside has no or almost no profiling.
    The diameter of the elongated inner part is preferably slightly larger than the diameter of the elongate outer part, for example two to three times larger. The diameter of the inner part is preferably in the millimeter range, for example, at about 2 to 5 millimeters.
    Advantageously, the train-pressure element is designed to be resilient both to train and on pressure in order to apply a driving action of the drive unit to the displaceable rail of the thrust element drive. Thus, the displaceable rail can be advantageously moved in two opposite directions with the train-pressure element, ie in retracting and Ausschieberichtung.
    If the train-pressure element loaded to train, the sliding rail can be moved for example in the closing direction of the thrust element and in the opening direction of the thrust element, the train-pressure element is loaded to pressure. The trajectory of the train-pressure element in space is advantageous identical in both directions of movement. Compared with rigid pressure-sensitive drive elements, the flexible tension-pressure element can advantageously assume a variable or almost any spatial orientation.
    According to a further advantage of the invention, the train-pressure element is made flexible over sections and formed rigidly over sections. In particular, the rigid areas are secured against bending. The flexibly configured sections are formed against bending in particular preferably automatically resetting, for example, rigid. In the direction of the longitudinal extension of the tension-pressure element, the rigid sections are preferably comparatively short, z. B. over a few millimeters long, followed by a few millimeters long flexible sections.
    According to an advantageous modification of the invention, the tension-pressure element is designed as a screw cable. Alternatively, a pitch cable can be provided as a train-pressure element. Both variants are particularly robust and reliable. Both cable types are preferably made of a steel material and have a spirally projecting contour or an outer contour with a regular pattern of elevations and depressions on the outside of the tension-compression element.
    It is also advantageous that the train-pressure element has a profiled outer side, which is designed for cooperation with a drive element of the drive unit. The profiled outside is preferably a protruding outer contour of the tension-pressure element. The profiled outer side of the tension-compression element, which is formed in particular by an outer part of the tension-pressure element, may be designed in the manner of an external thread, a spiral toothing or as a screw tooth portion. Thus, the train-pressure element is advantageously designed for a geared interaction with a toothed or worm wheel. The tension-pressure element is preferably drivable via a worm gear, wherein the worm wheel of the drive unit is selectively rotatable in both directions of rotation.
    The profiled outside may alternatively be formed, for example, in the form of grooves, notches or threads with raised portions therebetween, such as an external thread or the like, into which a counter thread or serration of a rotating pinion coming from the drive unit is driven, engages and driving on the train-pressure element acts.
    Another advantage of the invention results from the fact that a drivable by the drive unit driving element is provided which cooperates with the train-pressure element such that the tension-pressure element is translationally movable. The drive element may be, for example, a rotatably drivable drive wheel or friction wheel or pinion or a drive belt, a drive belt, a drive chain or the like.
    It is also advantageous that a drive element of the drive unit is designed to co-operate with a first train-pressure element and a second train-pressure element simultaneously. As a rule, two full or two partial extracts each receive a respective thrust element and the thrust element is moved with the respective displaceable rails or pull-out rails, advantageously both displaceable rails are each connected to a tension-pressure element. Therefore, it is advantageous if both train-pressure elements can be driven by a common drive unit. Preferably, the two tension-pressure elements are each extended with a sliding rail facing away from the section to a region in which the train-pressure elements are adjacent to each other. In this area, the position-fixed drive unit is present, for. B. in a rear area of the kitchen appliance or in the range of a kitchen appliance rear wall. Thus, for example, a driven-side pulley or a drive pinion of the drive unit with the two adjacent train-pressure elements co-operate or simultaneously drive, wherein an engagement portion of the driven-rotating drive pinion with the first train-pressure element and another engaging portion of the driven rotating drive pinion with the second train-pressure element is in driving engagement or meshes. Thus, also advantageous with exactly one drive element of the drive unit both train-pressure elements are driven simultaneously and similar.
    Alternatively, it is possible to drive each train-pressure element with a separate drive unit.
    It is also advantageous that guide means are provided which provide a spatial guideway for the train-pressure element. The guideway is in a cooperating with the train-pressure element section before the spatial profile of the train-pressure element. The guideway can act on the train-pressure element over the entire extension or length of the train-pressure element. The guideway acts in particular on all sections or only on selected sections of the tension-compression element, in particular in the areas in which the longitudinal axis of the tension-pressure element changes its spatial orientation, such. B. in deflection of the train-pressure element.
    The guide means can be used as frontally open and circumferentially closed hollow profile z. B. be configured tubular, in the interior of the train-pressure element is housed. Other embodiments are conceivable, for example, with circumferentially open portions of the guide means, for example, run around a groove-like or spiral around the train-pressure element. With the guide means almost any gradients or alignments of the train-pressure element can be specified in space. Preferably, the tension-pressure element is friction movable past the guide means, which can be predetermined by the material selection of the tension-pressure element and / or the guideway. Advantageously, deflections of the tension-pressure element or its longitudinal axis by up to approximately 90 degrees and more can be specified with the guide track.
    The invention also relates to a kitchen appliance such as an oven or an electric cooker, wherein a stove or stove push element drive is provided as explained above, with a push element on a side wall of the kitchen appliance is attachable and driven. Thus, the advantages discussed for oven or stove push element drive advantages are achieved on the kitchen appliance.
    The kitchen appliance has, for example, at least one push element, which are accommodated via two similar furnace or hearth push element drives on horizontally opposite areas of side walls, wherein the side walls opposite a heated inner volume of the kitchen appliance as a baking muffle limit. The oven or hearth push element drive may be directly attached to the side wall or to a side rail which is usually detachable and slightly protruding on the side wall.

B. baking trays, wherein a front upper field on the front of the oven simplistic without the operation of the oven 1 necessary switching or display means is shown. On the operating side, the oven 1 also has a baking-oven door 2 with a transparent viewing-window cut-out, wherein the oven door 2 is movably received on the oven 1 about a pivot axis which is horizontal in the utility state. In Figure 1, the oven door 2 is fully open or shown pivoted with a free front edge down. In the closed, pivoted-up state of the insulating oven door 2, a heatable interior of a baking muffle 3 of the oven 1 can be covered on the front side. The baking muffle 3 is, as usual, enclosed at the top, at the bottom and laterally by solid walls which comprise opposite side walls 4 and 5. Recirculation and heaters in the baking muffle 3 are not shown in detail.
    The oven 1 has a first oven push element drive 6 according to the invention, which comprises on both side walls 4 and 5 at the same horizontal height in each case a similar full extension 6a on which further parts of the furnace push element drive 6 are present.
    In addition, a second inventive furnace Schubelementantrieb 7 is present, which has on both side walls 4 and 5 vertically below the relevant full extension 6a each have a similar partial extract 7a with other parts of the furnace thrust element drive 7, wherein the two partial extensions 7a on the same horizontal Height are positioned.
    By means of the two identically designed full extensions 6a, a pushing element (not shown), for example a baking sheet or a baking grid, can be pushed out of the baking muffle 3 in the direction of P1 in the upper region of the baking muffle 3 and retracted in the direction P2 ,
    Below this, another comparatively flat pushing element (also not shown) can be pushed out of the baking muffle 3 in the direction of P1 via the similarly shaped partial separations 7a and can be pulled in again in the direction P2.
    The two solid extracts 6a and the two partial separations 7a are shown in Figures 1 and 3 in a maximally pushed-out position P1 position.
    In this case, a maximum distance in the direction P1 bridgeable with the pull-out 6a is greater than the maximum bridged in the direction P1 Ausziehstrecke with the partial extensions 7a, so that in each maximum possible extended position a respective leading edge 6b of the full extension 6a to the path a horizontally in the direction P1 in front of a front edge 7b of the partial extensions 7a (see Figure 3).
    With the full extension 6a, a thrust element supported thereon can accordingly be pushed out of the baking muffle 3 in the direction P1, whereby the pusher element is conveniently accessible to a user of the oven 1. In a thrust element pushed out with the partial extensions 7a, a rear region of the push element remains in the volume of the baking muffle 3. In the fully drawn-in position of the full-pulls 6a and part-pulls 7a, not shown, their leading edges 6b, 7b both extend to the common vertical V within the baking muffle 3 (see Fig. 3), so that the closed oven door 2 on the inside does not abut on the leading edges 6b, 7b and thus not on the pushers whose leading edges lie in the region of the leading edges 6b, 7b.
    FIG. 5 shows in perspective a part of the furnace push element drive 7 with the partial extension 7a, which comprises a shorter inner rail 16 with holding brackets 18 for attachment to the side wall 4 and a pull-out rail 17 displaceably received on the inner rail 16. The furnace push element drive 7 also has guide means 8, shown over a partial length, with a rigid, hollow, or optionally open, guide 12, in the volume of which an elongated flexible tension-compression element 11 is received and displaceable in the longitudinal direction of the guide 12 , The guide 12 accordingly forms with the internal volume a receiving space for the tension-pressure element 11. In the illustrated embodiment, the guide 12 is predominantly a hollow profile or hollow inside, for example formed as a metal tube whose inner diameter is slightly larger than an outer diameter of the tensile Pressure element 11 is. The curved guide 12, for example, extends beyond the partial extension 7a as far as a drive unit not shown in FIG. In the region of the partial extension 7a, the guide 12 extends partially between the inner rail 16 and the pull-out rail 17 into a front portion 16a of the inner rail 16.
    The displaceably accommodated in the fixed position guide 12 train pressure element 11 engages with its front end on the pull-out rail 17 and is connected, for example, with a rear end of the pull-out rail 17. The guide 12, which is positioned at a rear region, for example, behind the rear wall of the baking muffle 3, has a bend 21 by 90 degrees, wherein a leg of the guide 12 leads to the inner rail 16 and aligned parallel to the longitudinal axis of the inner rail 16 in the region of front end of the inner rail 16 ends. On the driven movement of the train-pressure element 11 will be discussed below.
    The full extension 6a comprises, in addition to the guide means 8, a carrier 13 which can be attached to a side wall 4, a middle rail 14 displaceably received thereon and a pull-out rail 15 displaceably mounted on the middle rail 14. One end of the pull-push device accommodated displaceably in the guide 12. Element 11 is connected to the center rail 14.
    For the movement of a thrust element, for example, with the two full extensions 6a accordingly two guides 12, each with a guided therein train-pressure element 11a and 11b, in Figure 4, a section offset by a section of the two somewhat verti kal Guides 12 in the region of a drive unit 9 is shown. The drive unit 9 is present in the rear region of the oven 1 and has a rotatably driven about the axis S pinion 20a. The pinion 20a is connected to the two train-pressure elements 11a and 11b via a respective recess 19, which are formed opposite in the two guides 12 in engagement with the driving force transmission. Upon rotation of the pinion 20a z. B. according to the direction of rotation P3 in Figure 4 meshes with an external toothing of the pinion 20a with portions of an outer profile of the train-pressure elements 11a and 11b such that the train-pressure element 11a along the associated guide 12 in its longitudinal or linear in Direction P4 and the train-pressure element 11b along the associated guide 12 is displaced in its longitudinal direction and linearly in the direction P5.
    In a direction of rotation predeterminable via the drive unit 9 or a control unit opposite to the direction of rotation P4, the tension-pressure element 11a can be displaced in the direction opposite P4 and the tension-pressure element 11b against the direction P5 along the respective guide 12 ,
    The train-pressure elements 11a and 11b can be pushed back and forth as described in accordance with the course of the guide 12 and thus movable with the full extension 6a thrust element under a compressive stress of the train-pressure elements 11a, 11b from the baking muffle 3 pushed out and retracted under a tensile stress of the train-pressure elements 11 a, 11 b in the baking muffle 3 or retracted.
    By a user for this purpose preferably with operating means on the oven 1 corresponding control commands are exercised, whereby the control unit is addressed, which controls the respective drive unit 9, with which the pinion 20a is driven.
    In a corresponding manner, a pinion 20b is rotationally driven for the two partial extensions 7a on a lower drive unit 10, which serves to drive the two train-pressure elements 11a, 11b in the respective guide 12 for the partial extensions 7a.
    The tension-pressure elements 11a, 11b are, for example, by an inner part or an inner, strand-shaped, flexible wire bundle of a plurality z. B. similar wires formed around which circumferentially fitting an outer part or a single flexible and thicker outer wire is placed.
    The outer wire is, for example, circular or polygonal in section and wound around the inner wire bundle helically without interruption. The tension-pressure element 11a or 11b is thus dependent on the direction of action of the force acting on the tension-pressure element 11a, 11b tensile and pressure stable loadable in particular for transmitting force of tensile and compressive forces in the longitudinal direction of the train-pressure element 11a and 11b, respectively.
    Not only are the mechanical properties of the tension-compression element significantly influenced by the outer part, but a profiling of the outer side of the tension-compression element 11a or 11b is provided with which the transmission of force or torque from the pinion 20a, 20b on the train-pressure elements 11a, 11b advantageously outside at all points or over the entire length of the train-pressure element 11a, 11b is made possible.
    The outer wire preferably forms a kind of male threaded portion on the tension-pressure member 11a, 11b.
    Figures 7 to 9 show another oven 22 according to the invention with a baking oven door 23 and a baking muffle 24, which is bounded laterally by side walls 25, 26. In FIG. 7, a full extension 27 and below a partial extension 28 are shown only on one side wall 25, a second associated full extension and a second associated partial extension on the opposite side wall 26 not being shown.
    In contrast to the oven 1, a drive of the full extension 27 and the partial extension 28 is realized with a spindle drive 29 and not with train-pressure elements in the oven 22. For the two opposite full extensions 27 is a drive unit 30 and for the two partial extracts 28, a drive unit 31 is provided. The z. B. as a geared motor behind a rear wall of the baking muffle 24 accommodated drive units 30, 31 respectively drive a first toothed belt 32 and a second toothed belt 33 circumferentially. The drivable by a drive wheel of the drive unit 30 toothed belt 32 is deflectively guided over two pulleys 34, so that in circulating toothed belt 32, the two discs 34 are each driven in the same direction rotating in the clockwise or counterclockwise. The discs 34 are present outside of the insulated baking muffle 24, wherein a disc 34 on a drive spindle 36 of one and a disc 34 on a drive spindle 36 of the other full extension 27 is mounted rotationally fixed. With circulating toothed belt 32 and rotation of the discs 34, the drive spindles 36 undergo a corresponding rotation about their longitudinal axis.
    The drive spindle 36 has an external thread and is mounted at the rear outside the insulated baking muffle and fixed to the front of a carrier 40 of the full extension 27. The carrier 40 is attached to the side wall 25. At a middle rail 41 of the full extension 27, a driver or a nut 38 is secured with an external thread of the drive spindle 36 matching internal thread through which the spindle 36 engages, so that the middle rail 41 upon rotation of the drive spindle 36 depending on the direction of rotation in the direction P1 relative to Baking muffle 24 can be pushed out and retracted in the direction of P2. By acting between the middle rail 41 and a pull-out rail 42 of the full extension 27 load transfer, e.g. with a cable pull-out rail 42 of the full extension 27 is shifted by twice the distance based on the imposed by the drive spindle 36 displacement of the center rail 41st
    As a result, a thrust element supported on the two opposite pull-out rails 42 of the full extension 27, such as a baking tray and the like, can be driven in a horizontally horizontally driven manner on the oven 22. FIGS. 7 and 9 show the maximum extended state of the full extension 27 and the partial extension 28.
    The present below the full extension 27 partial excerpts 28 and their respective inner rail 44 recorded pull-out rails 43 are driven directly in the same manner as the full extension 27, resulting in the drive unit 31, the timing belt 33, the discs 35 on the drive spindles 37 and driver or nuts 39 takes place on the respective extension rail 43.
    As a load-transfer element may alternatively be used to the timing belt 32 and 33, a chain, a cable or a band use.
