Description

The invention relates to a cooking appliance with a housing and a cooking chamber which can be closed by a door. The cooking device comprises a guide device, which has at least one guide slot, with which the door is coupled and with which the door is retractable when moving in the open state into a receiving space in the housing.

Cooking appliances, such as an oven or a microwave cooking appliance or a steam cooker, for example, are known from the prior art and have cooking chambers in which foodstuffs can be introduced for preparation. Such a cooking chamber is usually closed at the front by a door. Embodiments are known in which such a door is arranged on a housing and can only be pivoted about a horizontal or a vertical axis in order to open or close the door.

In addition, however, embodiments are also known in which such a door when transferring from the closed to the open state in a shaft or a receiving space under the cooking chamber is retractable into the housing. Such household appliances are for example from the WO 03/073004 A1 and the DE 10 2008 010 502 A1 known.

It is also known that cooking appliances have, for example, front vertical shutters arranged laterally to such a door on the housing, which are positioned, for example, as design applications. The vertical edge sides of this door usually have a certain gap to these front panels. Due to component tolerances, this gap is not the same at all points and over the entire extension. It may be provided that these front panels can be moved slightly in their position in order to then perform the appropriate gap dimension adjustment to the door. However, this is with regard to Attachment of these front panels difficult, on the other hand limits the gap setting.

It is an object of the present invention to provide a cooking appliance in which the positioning of a door, which is retractable into a receiving space of the cooking appliance, in particular in the closed state is improved.

This object is achieved by a cooking appliance having the features of claim 1.

An inventive cooking appliance comprises a housing and a cooking chamber which can be closed by a door. The cooking appliance furthermore has a guide device, which comprises at least one guide slot with which the door is coupled and with which the door can be retracted into a housing in the housing when moved to the open state. An essential idea of the invention is that the guide device is designed for height adjustment and thus to Justange the altitude of the door relative to the housing. It is thus created in a cooking appliance with a retractable door now also the opportunity to perform a position adjustment of the door. For this purpose, the guide device is designed multifunctional, since it is designed on the one hand to guide the door when sinking and retracting, on the other hand also this position change and in particular allows the height adjustment of the door in the closed state. This makes it possible, in particular in the closed state of the door whose position change at least on one edge side in the vertical direction and thus in the altitude, so that different relative positions of the door in the closed state to the housing and in particular to adjacent front panels on the housing are adjustable. It is therefore particularly preferred that, by virtue of this embodiment, even gap dimensions to adjacent front panels can be precisely and simply and reliably permanently and permanently set.

It is preferably provided that the guide slot is designed as a height adjustment device for the door at least in its closed state. Since just in this position state of the door front side, the gap dimensions to adjacent front panels represent, it is of particular importance to be able to adjust these gaps exactly and maintain.

It is preferably provided that a lower boundary wall of the guide slot is at least partially adjustable in height for height adjustment of the door. The guide slot is thus viewed in the vertical direction at least downwardly bounded by a boundary wall on which then optionally also a moving means, such as a roller or a ball bearing or the like can hang up and slide along when the door is moved relative to the housing. Just this boundary wall is thus essential and very direct influencing factor on the respective position of the door. It is therefore of particular advantage if just this component is not rigidly seated on the housing, but at least partially movable relative thereto, so that in mechanical interaction with the door an immediate change in altitude occurs. In addition, this boundary wall as such is also mechanically stable, so that it can ensure wear and height adjustment reliably and permanently wear.

It is preferably provided that the boundary wall at the front end in the altitude is adjustable. This embodiment is to be particularly emphasized, since just sitting in the closed state of the door of this movement means the door at the front end of the boundary wall or seated on this and thus just then at this point by the mobility and height change a very direct and accurate position change can be achieved , Moreover, in this embodiment, it is no longer necessary for the middle or rear sections of the boundary wall to be movable, so that they can be made rigid. On the one hand, this also improves the mechanical stability of the entire boundary wall and achieves the positionally accurate connection to housing parts.

It is preferably provided that the boundary wall is formed in the front region by a vertically movable insert. As a result, the advantages mentioned above can once again be favored and also optimized individually to the respective requirements. Because different cooking appliances can with regard to design regarding the size and weight and the component assembly be designed variable, so that here also different weights can act on such a boundary wall and in particular the movable part. By such a separate insert, which thus forms a portion of the lower boundary wall, it can be responded to individually, so that even here highest mechanical stresses and precise height adjustments can be accommodated.

It is preferably provided that the insert is designed as a strip and in particular made of steel, for example spring steel. This specification is preferred in terms of the above advantages.

It is preferably provided that an actuating device for the boundary wall is formed, which is movable with at least one actuating element relative to the boundary wall and can be coupled with this for height adjustment. Thus, in particular, a mechanical design is provided which acts as a separate component on the boundary wall in its movable section in order to effect its height adjustment. As a result, a very robust embodiment is achieved, which are insensitive in terms of mechanical strength and thermal influences, such as may be present in a cooking appliance. In particular, it is provided that the actuating element is arranged below the boundary wall. By this configuration already existing space is used meaningful and on the other hand, the guide slot is not unnecessarily limited and their space is not limited. In addition, this situation can also create a situation due to the weight, in which the raised and adjustable in height portion of the boundary wall is also supported from below and thus rests on the actuator quasi. A precisely set altitude therefore remains permanently well preserved.

It is preferably provided that the actuating device has a slide element which has a coupling wedge as the actuating element. The coupling wedge comprises an inclined contact surface, which is contacted with a contact surface on an underside of the lower boundary wall. In particular, this contact surface is bevelled on the underside of the lower boundary wall, so that when exposed to the Actuating element on these movable part of the boundary wall a jerk-free sliding along the contact surfaces is achieved together.

In particular, the coupling wedge is tapered at its front end and thus designed to taper at the end facing the front end of the boundary wall.

Preferably, it is provided that for height adjustment of the boundary wall, the slider element is horizontally displaceable and by sliding along the contact surface of the slider element on the contact surface of the boundary wall, this boundary wall is changeable in the altitude. The change in altitude is thus perpendicular to this horizontal movement, so that the relevant directions of movement are perpendicular to each other. By this configuration, a very simple operating principle can be realized, which is minimized in space requirements and still allows the altitude very directly and without a variety of additional transformer elements.

Preferably, it is provided that the slide element on its side facing away from the boundary wall bottom has a latching device which is designed to lock the position of the Schieberlements for latching with a counter-latching. This embodiment is advantageous in that a set position of the boundary wall can be permanently maintained because locked by the locking of the slider element and this on a housing component and thus can not be moved undesirable. Just when the slide element is arranged under the movable part of the boundary wall, then results in a very functional interacting action principle of the components.

In particular, it is provided in the context that the slider element is pressed into the counter-locking by the pushing on the slider element from above boundary wall. The position locking of the slider element is favored.

It is preferably provided that the height-adjustable part of the lower boundary wall in its normal position and thus in a non-upward raised adjustment position is preferably already mechanically contacted with the actuating element, so that no undesirable down pressing the boundary wall can be done. Starting from this basic position and the movement of the actuating element then only a situation is reached in which this movable part of the boundary wall is adjusted in height and pushed upwards, so that just then then from this movable part of the boundary wall acting down and on the slider element pressing force is larger, so that this pressing mechanism is increased from the movable part to the slider element.

It is preferably provided that the slider element is coupled to an eccentric, and by pressing the eccentric, the slider element is horizontally displaceable. As a result, a very uniform and even in very small sections and thus feasible in nuances horizontal displacement allow, so that also correspondingly small changes in the altitude of the movable part of the boundary wall can be adjusted.

It is preferably provided that the slide element can be locked in its displaced position with a securing element, in particular a securing screw. This configuration may be provided in addition to the above-mentioned locking device with the counter-locking or be formed without this additional locking mechanism.

Preferably, in a further embodiment, it is provided that two slide elements are each formed with at least one coupling wedge as actuating elements, which are coupled to each other in such a way that a second horizontal wedge in a second horizontal wedge direction perpendicular to the height direction moves into a further, perpendicular to the height direction and the first horizontal direction stationary second horizontal direction is movable and thereby the altitude of the boundary wall is adjustable. Thus, a mechanical interaction of two slide elements is created, which can move in different, relatively perpendicular directions when they act on each other and this movement is then transferred to the boundary wall so that it is then movable and raised in the third spatial direction.

It is preferably provided that the second coupling wedge is guided by a guide element in the second horizontal direction. For example, a corresponding bore can be provided here as a guide element.

In a further embodiment, it is preferably provided that two slide elements are each formed with at least one coupling wedge as actuating elements which are coupled to one another so that a first horizontal direction of the second coupling wedge perpendicular to the height direction can be adjusted in the height direction during a movement of the first coupling wedge and thereby the altitude of the boundary wall is adjustable.

In an advantageous embodiment, it is provided that tapered portions of the coupling wedges of the at least two slide elements abut each other and are movable relative to each other. This is also the very continuous and smooth movement is achieved, so that the altitude adjustment is very precise.

It is preferably provided that the first slider element is biased in the direction of the first horizontal direction by a spring. This can be achieved in the return to the initial state of an automatism.

It is preferably provided that in extension of the horizontal displacement direction of the slide element, the slide element is coupled to an adjusting element, in particular an adjusting screw, wherein the adjusting element is coupled in a front end of the slide element with this. Again, preferably a provision may be provided by a spring or an insert.

In a further embodiment, it is preferably provided that an actuating element of the actuating device designed as a slide element can be moved exclusively in the vertical direction and, for this purpose, an inclined contact surface on an underside of the slide element is coupled to a contact surface of the guide device. It is provided that an adjustable in a first horizontal direction adjustment moves the slider element in this first horizontal direction and By the coupled contact surfaces at the same time an adjustment in the height direction is possible.

In a further embodiment it is provided that the actuating element is an eccentric, which rests directly on an underside of the boundary wall and a height adjustment of the boundary wall is adjustable by a movement of the eccentric in a horizontal direction.

It is preferably provided that the guide device is designed for at least on one side of the door feasible altitude adjustment and is designed for adjusting the door to a side of the door to the housing arranged front panel.

Preferably, it is provided that the guide device is coupled to the door on two opposite sides in lower corner regions of the door, in particular via two separate guide slots, and is adapted to its adjustment of the altitude, the adjustment of the altitude on one side regardless of the adjustment the other side is feasible. As a result, tilting of the door can also take place, so that gap dimensions can be set to adjacent vertical diaphragms.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 is shown in a front view of a trained as an oven cooking device 1. The cooking appliance 1 comprises a cooking chamber 2, can be introduced into the food for cooking. The cooking chamber 2 is through walls of a muffle 7 ( Fig.2 ), which has a feed opening at the front, which can be closed by a door 3. In Fig. 1 the closed state of the door 3 is shown, so that it is virtually in the figure plane and thus in the xy plane.

The cooking appliance 1 also comprises a housing 4, in which the muffle 7 is arranged with the cooking chamber 2. Front panels 5 and 6 are arranged adjacent to the door 3 on the housing 4 at the front and to the side. The front panels 5 and 6 are strip-like elements that extend at least over the entire height (extension in the y-direction) and thus in the vertical direction of the door 3. They are fastened to the housing 4, for example via fasteners, such as plastic components. The position of these front panels 5 and 6 is always relatively accurate compared to the position of the door 3.

The door 3 is not a hinged door as such, but retractable into the housing 4 inside.

In the illustration according to Fig. 2 , in which the housing 4 is shown with the muffle 7, a receiving space 8 is formed under this muffle 7, in which the door 3, starting from the in Fig. 1 shown closed state when opening is einenkbar.

For this purpose, the cooking device 1 comprises a guide device 9. The guide device 9 is formed on the opposite vertical walls of the housing 4, respectively, so that the door 3 is correspondingly guided by movement on both opposite sides.

In Fig. 3 to an enlarged view of a portion of the guide device 9 is shown on one of the two sides. The guide device 9 comprises a guide slot 10, in which in particular a not shown ball bearing of the door 3 is guided.

The guide slot 10 comprises an upper boundary wall 11 and a lower boundary wall 12. In addition, a lateral boundary wall 13 is also provided.

The ball bearing of the door 3 sits quasi on the lower boundary wall 12.

When the door 3 is closed, as in Fig. 1 is shown, the bearing point of the ball bearing is always at the same location in the guide slot 10. This bearing point is at a front end 14 of the guide slot 10th

In the embodiment shown it is provided that the guide slot 10, in particular the lower boundary wall 12, is movable in sections and thus in the vertical position (y-direction) is changeable.

For this purpose, it is provided that thus the guide device 9 is formed for height adjustment of the door 3. In particular, in the closed state of the door 3, the guide slot 10 is designed as a height adjustment device for the door 3. Preferably, the lower boundary wall 12 is at least partially adjustable in height to the height position of the door 3.

For this purpose, a front portion 15 of the lower boundary wall 12 is arranged correspondingly relatively movable.

In the exemplary embodiment, it is provided that for this purpose a separate component in the form of an insert, which is in particular made of spring steel, forms this section 15. The insert in the form of portion 15 thus also forms the front end of the lower boundary wall 12, wherein the portion 15 to a front end 16 has, which then also forms the front end 14 of the guide slot 10.

The section 15 is strip-shaped and is in turn at least partially configured non-rectilinear and has a downwardly curved portion 17 on.

In Fig. 3 is a perspective view of an area of the guide device 9 analogous to the representation in Fig. 2 shown. In this first embodiment, the insert is shown in the form of the portion 15, which is fastened, for example via rivet connections on a support 18, which may be formed, for example, of plastic. The section 15 is mechanically coupled to an actuator 19. The actuating device 19 is arranged below the section 15 in the vertical direction and thus viewed in the y-direction. In the in Fig. 4 shown basic position of the section 15, in which no increase in the height and thus in the y-direction has occurred, the actuator 19 is already on an underside 20 of the portion 15 of the lower boundary wall 12 at.

The actuating device 19 comprises a slide element 21, which has a coupling wedge 22 with an inclined contact surface 23 at a front end, which faces the front end 14 of the guide slot 10 and thus also the end 16 of the section 15. The inclined contact surface 23 is preferably on an underside 24 of the section 15. In particular, this takes place in the region of the curved region 17 of the section 15.

The actuating element designed as a slide element 21 is in the embodiment only in a second horizontal direction, namely in the z-direction and thus in the direction of the extension of the guide slot 10 relative to the section 15 of the lower Sliding wall 12 slidable. For this purpose, an eccentric 25 is provided. If the eccentric 25 is actuated, then a horizontal displacement of the slider element 21 takes place in said second horizontal direction (z-direction), whereby, as shown in FIG Fig. 5 the insert is raised in the form of the section 15 and thus its position in the height and thus in the y-direction relative to the carrier 18 and thus also relative to the upper boundary wall 11 is adjusted. Since just in the closed state of the door 3, the ball bearing is positioned in the front end 14 of the guide slot 10 and rests on the section 15, thereby the door 3 is adjusted and adjusted in height accordingly.

This can be a in Fig. 1 shown gap dimension d1 and a gap d2, which form between the vertical side edges of the door 3 and the front panels 5 and 6, adjust and adjust.

In the exemplary embodiment, the actuating device 19 moreover also includes a securing element in the form of a securing screw 26, with which, as shown in FIG Fig. 5 shown shifted position of the slider element 21 can be detected.

In Fig. 6 is shown in a perspective view of another embodiment, in which, in contrast to the representation in Fig. 4 the locking screw 26 is not formed. When running in Fig. 6 In contrast, a locking of the slider element 21 is provided to the effect that a latching device 27 is formed on an opposite side of the section 15 bottom 28 of the slider element 21. This latching device 27 is latched with a counter-detent 29, which is formed on the carrier 18. The set by horizontal displacement of the slider element 21 position is then held and locked accordingly. This favors the design and arrangement of the section 15 at. Because already in the in Fig. 6 shown basic position, the slider element 21 is located on the underside 20 of the section 15. If the slider element 21 in the position according to Fig. 7 shifted, so again the section 15 is pushed up. However, it creates a pressing from above on the slider element 21 and in particular the coupling wedge 22 counterforce, through which then the slider element 21 is also pressed into the counter-latching 29 and the lock is better held.

This latching device 27 and the counter-latching 29 can also in the embodiments in 4 and FIG. 5 be provided.

By the latching device 27 and the counter-latching 29 is also a fine vertical adjustment of the insert in the form of section 15 is possible.

In the invention, it is thus no longer necessary, but may also be provided that the front panels 5 and / or 6 are arranged relative to the door 3 on the housing 4 movable and thus can be positioned adjustable.

Especially in systems that, for example, two cooking appliances 1 viewed in the vertical direction have arranged one above the other, and the front panels 5 and 6 each extend integrally over the entire height of both cooking appliances 1, such a change in position of the front panels 5 and 6 is no longer possible. Especially in such systems, the proposed invention is of considerable advantage, since the respective individual devices can then independently set the gap dimensions d1 and d2 individually by the positional change of the doors.

In Fig. 8 is a perspective view of a portion according to Fig. 4 to Fig. 7 shown with a further embodiment. In this embodiment, it is provided that the actuating device 19 has two separate slide elements 21a and 21b. They are positioned in series in the second horizontal spatial direction and thus in the z-direction. They each have a coupling wedge 22a and 22b, each of which includes inclined abutment surfaces which abut each other. The front slider element 21 b is also formed at its front end with a further coupling wedge 22 c, which in turn has a corresponding oblique upper contact surface 23. The front slider element 21 b is also connected to a guide member 30, which may be a bore, for example. By this guide member 30 in particular an exclusive mobility of the slider element 21 b is secured in the z direction. In this embodiment, in particular only the front second slider element 21b is in mechanical contact with the underside 20 of the section 15 or the underside 24. In contrast, the first slider element 21a can in particular only in a first horizontal spatial direction (x-direction). be moved, with an adjusting element 31 is provided in the form of an adjusting screw. When this screw is rotated, the first slide element 21a moves in the x-direction and, due to the mechanical coupling with the second slide element 21b, and the inclined contact surfaces of the coupling wedges 22a and 22b, the second slide element 21b is displaced in the z-direction. As a result, the insert is then automatically moved in the form of the section 15 in the height direction perpendicular to the two horizontal directions and thus changes the altitude.

In Fig. 9 For this purpose, the second state is shown, in which the section 15 is displaced maximally upwards at its front end 16, for which purpose the front second slider element 21 b has reached its foremost position. In Fig. 9 is the contact surface 22d of the slider element 21 b to recognize better.

In the execution according to FIGS. 8 and 9 It is thus provided that two slide elements 21 a and 21 b are each formed with at least one coupling wedge 22a and 22b as actuating elements which are coupled to one another in such a way that during a movement of the first coupling wedge 22a in a direction perpendicular to the height direction first horizontal direction ( x direction) second coupling wedge 22a in a second, perpendicular to the height direction and the first horizontal direction second horizontal direction (z-direction) is movable and thereby the altitude of the boundary wall 12 and in particular of the section 15 is adjustable.

In a further embodiment as shown in FIG Fig. 10 it is provided that a slide element 21 is provided. This is in an extension of the horizontal direction, in which the slider element 21 can be moved, coupled to an adjusting element 32, in particular an adjusting screw. The adjusting element 32 is coupled to a front end 33 of the slider element 21 with this. By turning on the adjusting element 32, the slider element 21 is pushed back and forth in the z-direction and thus in the second horizontal direction.

Preferably, it is provided that in addition an in 10 and FIG. 11 not shown spring or a depositor are present, with which then an automatic return to the basic position of the slider element 21 can be reached. Especially by a thread in the slider element 21 this is then moved in the horizontal direction with rotating screw and causes a height adjustment of the portion 15 by the application of the coupling wedge 22 on the underside of the portion 15. As already mentioned, the restoring of the slide element 21 can take place through the section 15 itself and the weight of the door lying on it, or by means of a separate spring acting counter to the adjusting element 32.

In Fig. 11 is the second state of execution in Fig. 10 shown in which a maximum height adjustment of the section 15 is set.

In Fig. 12 is shown in a perspective view of another embodiment. In this it is provided that two slide elements 21 a and 21 b, each with a coupling wedge 22a and 22b are formed as actuators. The slide elements 21a and 21b, in particular the coupling wedges 22a and 22b, are coupled to one another in such a way that a second coupling wedge is in a first horizontal direction (x direction) perpendicular to the height direction (y direction) during a movement of the first coupling wedge 22a 22b in the height direction (y-direction) is adjustable and thereby also the altitude of the lower boundary wall 12 and in particular of the section 15 is adjustable. In Fig. 12 Here again the undisguised basic position is shown, in Fig. 13 the maximum height adjustment of section 15 is shown. It is also the maximum upward position of the second slider element 21 b shown. This is achieved by starting from the representation in Fig. 12 the adjusting element 31 is rotated, thereby the first slider element 21a is displaced in the x direction and thereby the second slider element 21 b is lifted upwards.

In Fig. 14 a further embodiment is shown in a perspective view, in which a trained as a slide member 21 actuator is movable in the height direction and to an inclined contact surface 21 c on a bottom 21d has. This inclined contact surface 21c is coupled to a contact surface 34 of the guide device 9, wherein the slider element 21 is moved in this first horizontal direction by an adjusting element 31, in particular an adjusting screw, adjustable in a first horizontal direction (x direction) and by the coupled contact surfaces 21 c and 34 is simultaneously adjustable in height direction.

As a result, the section 15 is automatically adjusted in the vertical direction and thus changed the altitude. The underside 21d faces away from the section 15. In Fig. 15 in turn, the state is shown in which the section 15 is lifted up to the maximum and also the slider element 21 has reached the maximum height position.

In the embodiments described so far still locking devices 27 and counter detents 29 may be provided. In addition, each individual features and feature combinations of the individual embodiments may be provided in other embodiments or in addition to new, previously unexplained embodiments are summarized.

In Fig. 16 is shown a further embodiment in which no explicit own slide element is present. Rather, there is provided in the carrier 18, a trough or recess 35 in which an eccentric 25 is positioned and in the second horizontal direction (z-direction) can reciprocate. The eccentric 25 is located on the underside 20 of the section 15 also in Fig. 16 shown basic state, in which the section 15 is not yet raised to. If the eccentric 25 is then adjusted, it presses as shown in Fig. 17 go to section 15 above. In Fig. 17 is again shown the maximum raised state.

The guide device 9 is generally formed in all versions for at least on one side of the door 3 feasible Höhnlagenverstellung and thus configured for adjusting the door 3 to a side of the door 3 on the housing 4 arranged front panel 5 and / or 6. It can thus be a straight-line position of the door 3 in the direction of the height, if on both sides on the guide device 9 is carried out in each case an analogous lifting. If the door is to be tilted to some extent in the xy plane, such an altitude adjustment can only be done on one of the two sides. This is the preferred application in order to adjust the gap dimensions d1 and d2.
