Description

The invention relates to a cooking appliance with a housing containing a cooking chamber for preparing food. The cooking appliance also includes a door for closing the cooking chamber. A storage compartment is provided in the housing, into which the door can be stored from an open position. The cooking appliance has a hinge device by means of which the door can be pivoted outside the storage compartment between a fully closed position, thus sealing the receiving area or cooking chamber, and a fully open position. In this open position, the door is also located completely outside the storage compartment. Such a design is known, for example, from US Patent 2,925,081 A. However, in that case, moving the door from its fully open position into the storage compartment is relatively complex, and the mechanical design there can cause it to spread or jam during this movement. From DE 10 2005 051 017 A1, a cooking appliance with an outer housing and a door closing a front opening is known. The door is displaceable along a side wall of the appliance by the synchronous rolling of at least two gears on at least two horizontal and parallel racks. From DE 10 2013 006 559 A1, a device door with a drive mechanism is known. After opening, the door can be slid along a side wall of the device by rotating it around a hinge axis. From DE 17 84 748 A a rotary sliding fitting for sliding and pivoting door leaves is known. The object of the present invention is to create a cooking appliance in which a door, even when fully open and outside the storage space, can be easily and safely moved into the storage space. A cooking appliance according to the invention comprises a housing in which a cooking chamber for preparing food is formed. The cooking appliance also includes a door for closing the cooking chamber. Furthermore, the cooking appliance has a storage compartment for the door. This storage compartment is located, in particular, below the cooking chamber. The door can be inserted into the storage compartment from an open position. The door is pivotable between a fully closed and a fully open position outside the storage compartment by means of a hinge device. In the fully closed position, the cooking chamber is also closed by the door. In the fully open position, the door is still completely outside the storage compartment, but unrestricted access to the cooking chamber is maintained.In particular, the door in this open position is arranged in a horizontal position, from which it can then be slid into the horizontally oriented storage space. A key feature of the door is its connection to a carriage. This carriage is coupled to a rack and pinion mechanism, with the carriage and rack and pinion being two separate components. The carriage and rack and pinion mechanism allow the door to be moved from its open position (outside the storage compartment) to an internal position. In this internal position, the door is then at least partially retracted into the storage compartment. The design, incorporating the carriage and rack and pinion mechanism, allows for very simple and smooth movement of the door from the open position into the storage compartment, or from the storage compartment back to the open position. Furthermore, this mechanical concept ensures highly precise movement, preventing the door from jamming or becoming misaligned. According to the invention, the hinge device is fixedly connected to the carriage by means of hinges. The hinges preferably each have at least two hinge arms, in particular a hinge blade and a hinge housing, which are movable relative to each other. This mechanically rigid connection of the hinges to the carriage advantageously supports the pivoting movement of the door outside the storage compartment. This is because the hinges are arranged on a mechanically robust component, namely the carriage, which can then also absorb corresponding leverage forces. Furthermore, when the door is moved into the storage compartment, the position of the hinges is not obstructed by their attachment to the carriage, so that these hinges do not collide with other components when the door is moved into or out of the storage compartment.Furthermore, this robust and heavier trolley provides a suitable base, allowing the door to be swung outwards from the storage space. The carriage has a T-shaped support element, to which a hinge bracket is attached, specifically to a T-shaped foot of this support element. This design ensures a particularly stable connection between the hinge and the carriage. The aforementioned advantages are therefore especially pronounced. Alternatively or additionally, the invention provides that the carriage has rollers which are guided in a guide device for moving the carriage between the outer storage compartment position and the inner storage compartment position. The rollers ensure very smooth and even movement of the door into and out of the storage compartment. Furthermore, this design allows for quieter operation. In this context, the rollers can be made, at least partially, particularly on their running surfaces, of a noise-reducing material, especially plastic. The guide mechanism comprises an upper guide rail and a lower guide rail running parallel to it and spaced apart. The guide rails are oriented in the depth direction of the cooking appliance. The rollers are guided with some play, particularly in the vertical direction (i.e., vertically) within the guide track formed between the guide rails. This ensures very precise and mechanically stable guidance. Jamming or spreading of the rollers is thus prevented. It also prevents the rollers from jumping out of the guide track. In a particularly advantageous embodiment, the guide rails are provided with a groove on the edges bordering the guide track, and thus on the edges facing the guide track, into which the rollers extend. This further improves the guiding properties and the advantages already mentioned above. Preferably, the rack of the rack mechanism is formed on a guide rail. This results in a very compact design. Furthermore, the teeth are located in close proximity to the guide track and thus also to the rollers. This creates a highly functional operating principle with regard to the movement of the rollers on the one hand and the toothed coupling between the rack mechanism and a mating tooth on the carriage side. This improves the overall movement of the door when sliding it into and out of the storage compartment. Preferably, the rack is integrated into the underside of the lower guide rail, on the side facing away from the guide track. This reduces the number of components and ensures a mechanically stable positioning of the teeth. Positional tolerances between a separate rack and a guide rail are thus avoided. Furthermore, this design prevents the guide track itself from being affected by the teeth, thus ensuring the smooth movement of the rollers within the guide track. This also prevents the rollers from striking or rubbing against the teeth, ensuring that the rollers remain guided with minimal wear over the long term. The carriage features a guide plate on which rollers are mounted. The guide plate faces the storage compartment and extends vertically to a height greater than the height of the guide track between the guide rails. Thus, the guide plate effectively covers the guide track on the storage compartment side. Further support and stabilization are provided, in particular, when the guide plate rests against the inner side of the guide rails that define the guide track, and therefore on the storage compartment side. Moreover, such a guide plate ensures the mechanical stability of the rollers and constitutes a rigid, torsionally stiff component.By arranging two adjacent rollers on this common guide plate, these rollers can also be held permanently in a plane relative to each other, so that no unwanted offset occurs in a direction perpendicular to the guide plate and thus the movement of the rollers along the guide track can again be carried out with very little spreading and without jamming. Preferably, at least one gear is arranged on the carriage, which meshes with the rack and pinion assembly. In particular, meshing occurs between a rack arranged on the guide rail, especially on its underside, and preferably integrated into the carriage. This is also a very advantageous design because, firstly, the height of the carriage can be maintained very precisely. This is because, on the one hand, the rollers are held between two superimposed guide rails, albeit with a small degree of play. Secondly, the gear engages with the rack integrated into the guide rail on the underside opposite the upper side where this lower guide rail defines the guide track.Thus, on these opposite sides of the lower guide rail, a corresponding element is coupled – namely, the rollers on one side and the gear on the other – so that the height of the carriage is maintained at a precisely uniform level. This also facilitates smooth movement, ensuring a very smooth and even insertion and removal of the door into the storage compartment. Alternatively or additionally, according to the invention, the door is prevented from retracting into the storage compartment by a magnetic device when pivoting between the closed and open positions, and thus when moving outside the storage compartment. This ensures that the carriage is held securely in position during the door's movement from the closed to the open position or vice versa, by means of corresponding magnetic holding forces. This prevents the carriage from moving outside the storage compartment during this movement of the door. It also prevents the carriage from unintentionally retracting into the storage compartment during this pivoting movement of the door.This allows the pivoting movement of the door outside the storage space to be carried out very advantageously, precisely and with a high degree of local stability with respect to the axis of rotation around which the door pivots. This axis of rotation therefore does not move into or out of the storage space during the pivoting movement of the door from the open position to the closed position or vice versa, but remains stationary, as do the hinges and their axis of rotation. A further advantage arises in this context from the fact that very simple hinges, also used in conventional hinged doors, can be used for the entire assembly. Therefore, no complex, large, and thus expensive hinges are required, as are necessary in other known designs of retractable doors, when the retraction movement of the door into the storage space occurs at least partially in parallel with the pivoting movement from the open to the closed position. The door according to the invention can therefore be attached to the carriage with very simple hinges. A magnetic device for holding the carriage in a specific position is therefore very advantageous, since the magnetic holding forces also enable sufficient position fixation, while on the other hand, the further movement path of the door into the storage space from the fully open position allows for easy release without the need for mechanically complex release mechanisms. Preferably, the magnetic holding force generated by the magnetic device can be released by a release force in the linear direction of sliding the door into the storage compartment, starting from the open position of the door. In this advantageous embodiment, the magnetic holding force is automatically released by initiating the sliding of the door into the storage compartment from the open position. This is therefore a very simple solution. Furthermore, the user does not need to perform any additional actions to release such a holding device. It is also possible for the magnetic device to include electromagnets that can be controlled to generate their magnetic holding force. In this context, it may be possible for the electromagnets to be activated to generate the magnetic field until the door is fully open. Once this position is reached and, for example, detected by a sensor, the generated magnetic field is automatically deactivated and the electromagnets are no longer activated. Alternatively, it may be possible for the electromagnets to continue generating the magnetic field until a user explicitly activates a control element, which then deactivates the electromagnets. In an advantageous embodiment, at least one holding magnet of the magnetic device is arranged on the carriage. Preferably, this holding magnet is arranged on a connecting beam of the carriage extending in the width direction of the cooking appliance. This local arrangement facilitates magnetic coupling with a magnetically interacting counterpart component. Furthermore, in this position, the holding magnet does not interfere with the rollers in the guide track, nor with the rack and pinion mechanism. Undesirable interference with these components and the movement guidance caused by the holding magnet is thus prevented. It is preferable to have a stop element arranged on this connecting support. Such a stop element prevents the holding magnets from impacting too hard against a magnetically interacting counterpart when the door is pulled out from an internal storage compartment position to the fully extended storage compartment position, which also corresponds to the open position of the door. This extended end position, defined by the external storage compartment position, is therefore not reached by a hard impact or stop, but is dampened to a certain extent by this stop element. The stop element can be designed to be deformable or elastic, at least in some areas, so that reaching the door's final position in the extended state, and thus the external storage compartment position, is achieved in a dampened manner.This also prevents damage to a holding magnet. Preferably, the holding magnet is coupled to a magnetically interacting bridge of the housing, located under the door, which itself constitutes a magnetically interacting component. This positional arrangement is highly advantageous because it ensures high magnetic interaction functionality, reliably holds the carriage in the correct position, and prevents the holding magnet and the magnetically interacting bridge from obstructing the door's movement. This prevents unwanted collisions or rubbing of the door. In an advantageous embodiment, the movement between the outer and inner positions of the storage compartment is exclusively linear or horizontal. This very simple direction of movement facilitates easy handling of the door when moving it into or out of the storage compartment and ensures smooth, jam-free movement along this specific path. Such a specification of the movement path in this section can be designed very simply and, in particular, linearly through the design of the rack and pinion mechanism and the guide. Complex geometries for the rack and pinion or the guide track are not required, which further improves the smooth, jam-free movement of the door. A further independent aspect of the invention relates to a cooking appliance with a housing in which a cooking chamber for preparing food is formed, and with a door for closing the cooking chamber, and with a storage compartment in which the door can be moved from an open position, wherein the door can be pivoted outside the storage compartment between a fully closed and a fully open position by means of a hinge device, wherein the door is prevented from retracting into the storage compartment during pivoting between the closed and open positions by a magnetic device. This allows for safe and precise pivoting of the door outside the storage compartment with respect to the position of the pivot axis.The magnetic device holds the door's pivot axis in a precise position, ensuring that the door's pivoting motion is not affected by its simultaneous retraction into the storage compartment. This prevents jamming or jerky movement. Furthermore, the movement of the door pivoting outside the storage compartment is completely decoupled from the movement of moving the door in or out of the compartment; these movements do not overlap but occur sequentially. The magnetic device is also simple to construct, yet highly functional and consistently precise. Therefore, a complex mechanism is not required to achieve this function.Furthermore, the magnetic device also simplifies the transition between movement sequences, since only the magnetic holding forces need to be overcome and no extensively coupled mechanical components need to be laboriously uncoupled or recoupled. The retraction of the door into the storage compartment on the movement path between the closed position and the open position of the door is thus prevented by magnetic holding forces of the magnetic device. Embodiments of the first independent aspect of the invention are to be regarded as advantageous embodiments of the second aspect. The terms “top”, “bottom”, “front”, “back”, “depth”, “latitude”, “height”, etc. indicate the positions and orientations that would be present when the device is used and positioned as intended, and when an observer is standing in front of the device and looking towards it. Further features of the invention are evident from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations without departing from the scope of the invention. Thus, embodiments that are not explicitly shown and explained in the figures, but which can be derived and generated from the explained embodiments by separate combinations of features, are also to be considered as encompassed and disclosed by the invention. Embodiments and combinations of features that do not exhibit all the features of an originally formulated independent claim are also to be considered disclosed.Furthermore, embodiments and combinations of features, in particular those set out above, are to be considered disclosed which go beyond or deviate from the combinations of features set out in the cross-references of the claims. Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a perspective view of an exemplary embodiment of a cooking appliance according to the invention; Fig. 2 a perspective view of partial components of the cooking appliance according to Fig. 1; Fig. 3 a perspective view of a trolley of the cooking appliance according to Fig. 1; Fig. 4 a schematic side view of partial components of the cooking appliance according to Fig. 1 with a door fully closed; Fig. 5 a side view of the components according to Fig. 4 with the door fully open and positioned outside a storage compartment; and Fig. 6 a side view according to Figs. 4 and 5 with the door inserted into the storage compartment. In the figures, identical or functionally equivalent elements are given the same reference symbols. Figure 1 shows a simplified representation of a cooking appliance 1, which is, for example, an oven. The cooking appliance 1 comprises a housing 2 in which a receiving chamber 3 is formed for receiving and preparing food. The cooking chamber 3 is bounded by the walls of a muffle (not shown). The receiving chamber 3 can be closed at the front, and thus in the depth direction (z-direction), by a door 4. The door 4 is shown in a fully closed position in Figure 1. The door 4 has, for example, a handle 5. The cooking appliance 1 also includes, for illustrative purposes only, an operating device 6 with a display unit 7 and operating elements 8 and 9. Furthermore, a storage compartment 10 is formed in the housing 2, into which the door 4 can be recessed. Fig. 2 shows a perspective view of the household appliance for preparing food or the cooking appliance 1 with its subcomponents. The door 4, which is not shown in Fig. 2, is pivotably mounted via a hinge device 11, which has two hinges 12 and 13. The hinge 12 comprises two hinge arms: a hinge housing 12a and a hinge arm in the form of a hinge blade 12b. The hinge housing 12a is directly connected to the door 4 and pivotally connected to the hinge blade 12b. Similarly, the hinge 13 also has a hinge housing 13a and a hinge blade 13b. With these hinges 12 and 13, the door 4 can be pivoted between a fully closed position shown in Fig. 1, in which the door 4 is completely outside the storage compartment 10, and a fully open position, in which the cooking compartment 3 is accessible and the door 4 is also completely outside the storage compartment 10. In the fully open position, the door 4 is horizontally oriented and thus arranged in an xz-plane. The door 4 is coupled to a carriage 14 via hinges 12 and 13. For this purpose, the hinge plate 12b is connected to a T-shaped support element 15. In particular, the hinge plate 12b is attached to a T-base 15a of this T-shaped support element 15. Similarly, on the side opposite in the width direction (i.e., in the x-direction), a T-shaped support element 16 is also arranged, with the hinge plate 13b here also being firmly connected to a T-base 16a of the support element 16. The support elements 15 and 16 are components of the carriage 14. The carriage 14 also has a connecting beam 17 that extends in the width direction. Furthermore, the carriage 14 comprises a guide plate 18, which is preferably connected to a mounting plate 19. Rollers (not shown) are attached to this guide plate 18. As can be seen, the connecting support 17 and the support element 15 rest on the mounting plate 19 and are also connected to the guide plate 18. A guide plate 20 and a mounting plate 21 are provided on the opposite side. As can be seen there, two rollers 22 and 23 are rotatably arranged on this guide plate 20, which is vertically oriented and thus extends in the yz plane. The carriage 14 allows the door 4 to be moved into and out of the storage compartment 10 from its fully open position with a purely linear movement extending in the z-direction. This involves moving the door 4 from its open position, which is also an outer position within the storage compartment, into the storage compartment 10 by linearly and straight-line. As already explained, hinges 12 and 13 are permanently connected to the carriage 14. The cooking appliance 1 further comprises a guide device 24, 25 which has an upper guide rail 26 and a lower guide rail 27 arranged parallel to and spaced apart from it on a first side. The guide rails 26 and 27 are oriented in the z-direction. On the opposite side, the guide device 24 has a corresponding upper guide rail 28 and a lower guide rail 29. The carriage 14 is coupled to the rails 26 to 29. The guide rails and their positional arrangement create a guide track 30 or 31 in between. The rollers 22 and 23 run in these guide tracks 30 or 31, as do the two rollers (not shown in Fig. 2) which are arranged on the guide plate 18. As can be seen in Fig. 2, the lower guide rail 27 has a recess or groove 33 at its upper edge 32, which faces the upper guide rail 26 and thus also defines the guide track 30. The rollers 22 and 23 run in this groove 33. In particular, it is also provided that a recess or groove 35 is formed on a lower edge 34 of the upper guide rail 26, which thus limits the guide track 30 from above, into which the rollers 22 and 23 also engage. The design of the guide rails 28 and 29 is also similar, although for the sake of clarity in Fig. 2 no further reference numerals are assigned. The rollers 22 and 23 are arranged in the vertical direction and thus in the y-direction with a clearance in the guide track 30 so that they can roll along smoothly. Furthermore, a rack and pinion assembly 36 is provided. The rack and pinion assembly 36 comprises a first rack 37, which is integrated into the lower guide rail 27 and is formed on a lower edge 38 of the guide rail 27 facing away from the guide cam 30. A further rack 39 is also formed on the lower guide rail 29 accordingly. A gear 40 is arranged on the carriage 14, in particular on the connecting support 17, which meshes with the teeth of the rack 37. Correspondingly, another gear, which is not visible in Fig. 2, is arranged on the opposite side, which then meshes with the teeth of the rack 39. The racks 37 and 39 are straight and run horizontally. They are integrated and thus formed as a single piece with the guide rails 27 and 29. Furthermore, a magnetic device 41 is provided. The magnetic device 41 prevents the door 4 from retracting into the storage compartment 10 when pivoting between the closed and open positions. This means that the carriage 14 is held in the forward position shown in Fig. 2 by the magnetic holding forces of the magnetic device 41 when the door 4 is pivoted between the fully open and fully closed positions. Figure 3 shows a perspective view of the carriage 14. It can be seen that the magnetic device 41 has a first holding magnet 42 and a second holding magnet 43. Furthermore, it is preferably provided that stop elements 44 and 45 are arranged adjacent to the holding magnets 42 and 43 on the connecting carrier 17. These stop elements 44 and 45 prevent an undesirably hard stop of the carriage 14, and thus also of the holding magnets 42 and 43, when reaching the outer storage compartment position. This also prevents an undesirably hard stop when the holding magnets 42 and 43 come into mechanical contact with a magnetically interacting component, in particular a magnetically interacting bridge 46 (Figure 2). The bridge 46 is arranged externally to the carriage and is fixed in position. It is located, in particular, below the door 4 and is, in particular, a housing part. Fig. 3 shows the additional gear 47 which meshes with the rack 39. In Fig. 4, a side view shows the door 4 in the fully closed position. The holding magnets 42 and 43 are connected to the bridge 46, and the magnetic holding force is established, so that the carriage 14 is fixed in its position shown. If, starting from the position of the door 4 shown in Fig. 4, it is now opened and pivoted downwards, it reaches the lower, fully open position shown in Fig. 5, in which it is still completely outside the storage compartment 10. Due to the magnetic device 41, the carriage 14 remains positionally unchanged over this entire pivoting path, as also shown in Fig. 5. In this horizontal position of the door 4, and starting from this position, the door 4 can then be inserted into the storage compartment 10. To do this, it is moved in the direction of travel, and thus in the z-direction, which also represents the depth direction. The corresponding force applied in this z-direction then overcomes a threshold value of the magnetic holding force of the magnetic device 41, releasing the magnetic device 41. The carriage 14 is then pushed into the storage compartment 10 by a straight horizontal movement, thus assuming an internal storage compartment position from the external storage compartment position of the door 4 shown in Fig. 5. As illustrated in Fig. 6, the fully inserted internal storage compartment position of the door 4 within the storage compartment 10 is then reached.
