Description

The invention relates to a cooking appliance with a door for closing a cooking chamber and with a housing in which a storage space is formed into which the door can be lowered, wherein a guide part is arranged in the storage space, on which a guide track for a guide carriage of the cooking appliance is formed for guiding the lowering movement of the door into the storage space.

From the EN 10 2018 201 950 A1 and the EN 10 2020 208 891 A1 Cooking appliances with retractable doors are known which are coupled to guide carriages, whereby the guide carriages are guided by rollers in guide slots.

Furthermore, the EN 10 2015 226 009 A1 a cooking appliance with a retractable door is known. There, the storage space for the door is also delimited by vertical, in particular plate-like, side walls. In these side walls, which represent technical parts, guide tracks for a sliding block or a guide slide are also formed. In this design, these guide tracks are formed far down in the technical parts in the vertical direction of the cooking appliance and thus also in the vertical direction of these technical parts. This allows a guide movement of the door to have a specific sequence. In particular, in this design, it is provided that a front end and a rear end of this guide track are formed practically immediately adjacent to a lower edge of this technical part. The door is thus arranged far down at the start and end of the movement.

This type of design limits the ability to lower relatively wide doors, as the installation space is limited not only in terms of width but also in height.

The object of the present invention is to provide a cooking appliance with a retractable door, wherein the guidance of the guide carriage is improved. In this context, a concept should therefore also be made possible in which the flexibility with regard to the use of different doors is improved.

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

One aspect of the invention relates to a cooking appliance with a door for closing a cooking chamber. The cooking appliance also has a housing in which a storage space is formed. The door can be lowered into this storage space. The storage space is a space separate from a cooking chamber of the cooking appliance. Food can be placed in the cooking chamber for preparation. A guide part is arranged in the storage space, on which a guide track for a guide carriage of the cooking appliance is formed for guiding the lowering movement of the door into the storage space.

The guide part has a first guide track, which is upper when viewed in the vertical direction of the cooking appliance. The guide part also has a second guide track which is separate from the first upper guide track and lower when viewed in the vertical direction. The guide carriage has at least three separate guide elements which rest on the two guide tracks for guiding the guide carriage, in particular when the guide carriage is moved simultaneously. At least one guide element is arranged resting on the upper guide track when viewed in the vertical direction from above. At least one further guide element is resting on the lower guide track when viewed in the vertical direction from below. Such a concept enables particularly advantageous and improved guidance of the door into or out of the storage space. In particular, it also enables a very compact guide system to be provided. This means that space can be saved in the vertical direction. This in turn makes it easier for the cooking chamber of the cooking appliance to be made larger when viewed in the vertical direction, although the dimensions of the cooking appliance in the vertical direction can then remain unchanged. In addition, such a guide carriage, which is coupled with guide elements on both sides from above and from below with two guide tracks, viewed in the vertical direction, makes it possible to carry out the guide movement with less play. This means that the guide carriage can be guided more precisely because tolerances are minimized and, in this context, forces and force peaks that act on the guide carriage and the guide elements when the door is moved into or out of the storage space can be better absorbed. Due to the specific number and positional arrangement of the guide elements and the specific coupling with the guide tracks mentioned, the guide part can also be made lower, particularly in the vertical direction.

In one embodiment, at least one guide element can be a roller. It is possible that all guide elements are formed by rollers. This enables the guide carriage to move particularly evenly and smoothly along the guide tracks.

In another embodiment, at least one guide element can be a plain bearing. It is possible that all guide elements are designed as plain bearings. In such an embodiment, the guide elements can be designed to be very space-saving and compact. This also minimizes the structure of the guide carriage, particularly in the vertical direction. A plain bearing is arranged on the guide carriage, in particular, without its own possibility of relative movement.

In one embodiment, two guide elements rest on one of the two guide tracks. The at least one further guide element rests on the other guide track. It can be provided that this further guide element is positioned between the other two guide elements when viewed in the depth direction of the cooking appliance. By offsetting the three guide elements in a specific spatial direction, a particularly mechanically stable fit on both guide tracks is achieved. A tilting movement of the guide carriage about an axis oriented in the width direction of the cooking appliance can thus be better avoided. This also allows the guide elements to rest more evenly on the respective guide tracks. This also results in a more jam-free and spread-free movement of the guide carriage on the guide part.

In one embodiment, two guide elements rest on the upper guide track from above. The third additional guide element then rests on the lower guide track from below.

In another embodiment, one guide element rests against the upper guide track from above and two further guide elements rest against the lower guide track from below.

In another embodiment, it can be provided that four separate guide elements are arranged on the guide carriage. In such an embodiment, two guide elements are preferably located on the upper guide track from above and two further guide elements are located on the lower guide track from below.

In such an embodiment, two front guide elements, one of which rests on the upper guide track and the other on the lower guide track, can be arranged at the same depth when viewed in the depth direction. In addition to this or instead of this, it can be provided that two further rear guide elements, one of which rests on the upper guide track from above and the other on the lower guide track from below, are arranged at the same depth.

In one embodiment, the lower guide track is designed to be straight. In particular, it extends horizontally in the depth direction of the cooking appliance. Such a straight guide track requires practically no space in the vertical direction, since it has no curvature or curved section. This allows a space-saving concept to be further improved when viewed in the vertical direction.

In one embodiment, the upper guide track is designed to be straight. In particular, it extends horizontally in the depth direction of the cooking appliance. This also offers advantages in terms of a compact structure in the vertical direction. This also contributes to the fact that the storage space can be reduced in height and the cooking space can therefore be enlarged.

In one embodiment, the guide part can be designed as a rod. Its longitudinal axis can extend in the depth direction of the cooking appliance. In such an embodiment, an upper side, in particular a ceiling wall of this guide part, can form the upper guide track. The underside or a floor side of the guide part can form the lower guide track. A guide part that is designed as a rod or beam can be solid. Especially when the guide part is designed as a rod or beam, it has a very low height in the vertical direction. This also ensures that the guide elements of the guide carriage are only spaced apart in the vertical direction so that this rod-like guide part is arranged in between. This also supports the compact design of this guide system.

In principle, it can be provided that, viewed in the vertical direction, the guide part with its guide tracks is arranged between the at least one upper guide element and the at least one lower guide element. Such a sandwich structure with a preferably single guide part for this guide carriage, which lies between these guide elements, particularly supports the above-mentioned advantages with regard to compact construction, mechanical stability and smooth guidance.

However, it is also possible for a guide part to be made in two parts. In this context, a first guide part element can have the upper guide track. A second guide part element can have the lower guide track. In such an embodiment, the guide part elements can also be arranged at a distance from one another when viewed in the vertical direction.

In one embodiment, the guide carriage is coupled to the door with a hinge device of the cooking appliance. This hinge device supports the pivoting movement of the door when moving into the storage space and when moving out of the storage space, so that this pivoting movement can be carried out independently of the sliding movement of the guide carriage. In particular, the hinge device as a whole can be arranged in a fixed position in the housing of the cooking appliance. In particular, the arrangement can be formed on a base assembly of the housing. The hinge device preferably has its own guide components, such as the rollers. In one embodiment, these can engage in guide slots formed on the side of the door, such as guide grooves in particular. This allows the door, in particular the door leaf of the door, to be moved relative to the hinge device and is guided in the movement by the guide elements of the hinge device engaging with them. It is also possible for the door, in particular the door leaf, to have a coupling device on a lower part. This coupling device is intended to couple to the guide carriage. In particular, this articulated coupling is designed to be permanent, so that the door leaf of the door can be moved, in particular also pivoted, relative to the guide carriage. In particular, it is provided that this coupling between the coupling device and the guide carriage is designed to be articulated.

In one embodiment, at least one guide element, viewed as a whole, is mounted on a support of the guide carriage in a position that can be changed. This allows the guide element to be in constant contact with the guide track in a particularly advantageous manner. Tolerances can then be compensated for by changing the position of the guide element on the support. In one embodiment, the at least one guide element can be mounted on the support with a spring. The positional change is thus made possible automatically by the spring force of the spring acting on the guide element. This creates a particularly advantageous, robust system that is very fast in terms of changing the position.

In one embodiment, at least one guide track is designed in the form of a channel. This makes it possible for a limitation of the guide track to be formed perpendicular to the longitudinal axis of the guide track. This limits and in particular prevents an undesired movement of a guide element perpendicular to the longitudinal axis of the guide track. This achieves a particularly straight-line guidance of the guide element in the guide track, in particular in the depth direction.

In one embodiment, at least one guide track is designed to be hump-like in cross section and thus perpendicular to its longitudinal axis. In particular, it can be convexly curved or trapezoidal. Such a shape of the guide track also prevents undesired slipping of the guide element relative to the guide track when viewed in the width direction. Such a shape of the guide track also achieves particularly straight guidance of the guide elements on the guide track.

In one embodiment, a running surface of a guide element has a groove-like shape into which the hump-like region of the guide track engages. The above-mentioned advantages are particularly supported by these complementary shapes of the running surface of the guide element on the one hand and the guide track on the other.

In one embodiment, the guide track is arranged at a distance of between 20 mm and 26 mm from a base of the cooking appliance housing, viewed in the height direction of the cooking appliance. In addition to this, or instead of this, in one embodiment, the lower guide track is arranged at a distance of between 16 mm and 20 mm from a base of the cooking appliance housing, viewed in the height direction of the cooking appliance. The upper guide track is always higher than the lower guide track. By positioning the guide tracks as far down as possible, but unrestricted movement of the guide elements on the guide tracks is still achieved. This also does not affect the door moving in and out of the storage space. Nevertheless, it is also advantageously supported by the fact that the storage space can be made smaller in height and thus the cooking space can be increased in height.

Preferably, viewed in the width direction of the cooking appliance, a guide carriage and a guide part are formed at opposite ends. The two guide carriages and/or the two guide parts can be of the same design. In particular, the above-mentioned explanations and embodiments then apply to both guide carriages. The above-mentioned coupling device can then also be coupled to both guide carriages, in particular to a connecting rod that connects the two guide carriages.

The guide carriages formed on opposite sides are preferably connected to a connecting rod so that the position relative to one another can be maintained and no tilting or twisting occurs with respect to one another with respect to the movement. This position coupling between the guide carriages enables a smooth and even movement along the guide tracks on the guide parts. The door is advantageously connected to these guide carriages at its lower end, in particular rotatably connected to them. The guide carriages are separate components from the hinge devices. The guide carriages are preferably connected to the door in a movement-coupled manner, with an axis of rotation being formed at the connection point, around which the door can then rotate relative to a guide carriage. In contrast, the hinge device with the rollers already explained above not only enables a relative movement with respect to rotation with respect to one another, but also a relative displacement movement between the door and a hinge arm is provided by the guide grooves or guide slots in the door, which are also formed on the side edges and have already been mentioned.

In an advantageous embodiment, it is provided that the storage space has a clear width of less than or equal to 45 mm, in particular between 40 mm and 44 mm, in the vertical direction at least at one entrance. It is preferably provided that this clear width, viewed in the vertical direction, is formed over at least 50 percent, preferably at least 80 percent, in particular at least 90 percent, of the depth of the storage space measured in the depth direction.

This type of design makes the storage space particularly compact, so that the cooking space can be made available with maximum dimensions. If the housing of the cooking appliance has a standard size, this compact storage space can maximize the cooking space. Nevertheless, it is still possible to slide a wide door into and out of the storage space.

In an advantageous embodiment, the door has a thickness of between 35 mm and 45 mm, in particular between 38 mm and 42 mm, preferably 40 mm. With such a design, it is then also possible for the door to have a multi-pane package with at least three panes, whereby a front pane, an inner pane and at least one intermediate pane can be provided. The panes are oriented parallel to one another and represent plate-like elements, in particular made of real glass. Especially with several door panes, in particular at least four such separate panes, the cooking appliance can also be designed with a pyrolysis function.

Especially with such a design, in which the door has the above-mentioned advantageous thickness and the storage space has the above-mentioned advantageous height, whereby the thickness is of course always smaller than the height of the storage space, a relatively thick door can be retracted into a storage space that is then only slightly higher. The above-mentioned mechanism then makes it possible for the door to be retracted or extended accordingly, even though the storage space is only slightly higher than the thickness of the door. In particular, this is achieved by the fact that when the door is retracted during the pivoting movement, in particular starting from the closed position into a horizontal open position, it does not or only slightly retract into the storage space, and the main retraction movement takes place starting from the horizontal open position, so that the linear movement of the door into the storage space essentially only takes place after the pivoting movement.

In an advantageous embodiment, it can be provided in addition to or instead of this that the door has a width of between 530 mm and 545 mm, in particular between 535 mm and 540 mm, on its outside in the width direction. With such a wide door, the gap dimensions can be improved. In particular, in this context, the gap dimensions to adjacent components such as front strips, which are designed as visible components or external parts of the cooking appliance on the front, can be improved. In particular, these gap dimensions can be set relatively small. In this context, the above-mentioned design of the door with its specific width dimension can create a uniform front appearance between cooking appliance variants, on the one hand with only a hinged door, on the other hand with the retractable door described above. When the doors are closed, a uniform appearance can be offered for these two cooking appliance variants.

The terms “top”, “bottom”, “front”, “back”, “horizontal”, “vertical”, “depth direction”, “width direction”, “height direction” etc. indicate the positions and orientations that occur when the device is used and arranged as intended and when an observer is standing in front of the device and looking in the direction of the device.

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

In 1 A schematic perspective view of a household appliance 1 designed as an oven is shown. The household appliance 1 has a housing 2 in which a cooking chamber is formed, delimited by a muffle (not shown). Food can be placed in the cooking chamber for preparation. The cooking chamber can be closed at the front by a door 3, which 1 shown in the closed end position. A handle 4 is formed on the front side of the door 3.

In addition, the oven has an operating device 5, which in terms of position and display has only an example of a display unit 6 and operating elements 7 and 8.

The housing 2 may have walls 9, 10, 11 and 12.

The door 3 can be pushed or sunk into the housing 2 in its lower area 13, which is possible when the door 3 is transferred from the 1 shown closed end position into the fully open and sunk end position. The door 3 is then arranged sunk into a free space in the housing 2, whereby a storage space 14 is formed through this free space, which is arranged under the cooking chamber and separated from it by a corresponding partition wall.

The door 3 is connected to door hinges shown and marked as examples, which are examples of hinge devices 15 and 16, and can be pivoted via these and can be retracted and extended into the aforementioned storage space 14.

In 2 a vertical sectional view (section plane yz plane) of the cooking appliance 1 is shown. Here, the cooking chamber 17 can be seen, which is delimited by the muffle mentioned.

It can be seen here that the storage space 14 has a clear width w which is measured in the height direction (y-direction) and which is in particular between 40 mm and 44 mm, preferably between 42 mm and 43 mm.

A thickness d ( 2 ) of the door 3 is preferably between 38 mm and 42 mm, in particular 40 mm.

A width b of the door 3 measured in the width direction (x-direction) as shown in 1 is preferably between 530 mm and 545 mm, in particular between 535 mm and 540 mm.

Furthermore, a front pane 3a and an inner pane 3b and an intermediate pane 3c of the door 3 are also shown.

As in 3 is shown, which represents a view in the negative x-direction, the hinge device 15 can have a hinge housing 18. This can be arranged stationary in the housing 2, viewed as a whole. The hinge device 15 also has a bearing unit 19, which has a bearing bracket 20. At least one guide element 21, here a roller, is rotatably mounted on the bearing bracket 20. This guide element 21 engages in a groove-like guide slot 22, which is formed on a side edge 23 of the door 3 and extends in the vertical direction when the door 3 is closed. The guide element 21 is thus guided in this guide slot 22, which is open laterally to the outside when viewed in the width direction.

The guide slot 22 is formed in particular on a door leaf 24 of the door 3. The door leaf 24 is the plate-like front element of the door 3.

The door 3 also has a coupling device 25. The door leaf 24 is coupled to at least one guide carriage 26 of the door 3 using this coupling device 25. In particular, a guide carriage 26 is arranged on opposite sides in the width direction. In particular, an articulated connection is formed here so that the door leaf 3 can pivot relatively in the state coupled to the guide carriage 26, in particular about an axis oriented in the width direction (x-direction).

The cooking appliance 1 also has a guide part 27. The guide part 27 is arranged in the storage space 14. In particular, a guide part 27 is arranged on opposite sides in the width direction.

The guide carriage 26 is guided on this guide part 27. The guide part 27 can be designed like a rod or a beam. It extends with its longitudinal axis in the depth direction (z direction) of the cooking appliance 1. It is arranged in particular on a side wall that laterally delimits the storage space 14. In the exemplary embodiment shown, the guide part 27 has an upper guide track 28 as viewed in the height direction (y direction) of the cooking appliance 1. In one exemplary embodiment, this upper guide track 28 is straight, in particular over at least the section along which the guide carriage 26 can move, in particular with a guide element. In addition, the guide part 27 has a lower guide track 29 as viewed in the height direction. This is arranged under the upper guide track 28. In one exemplary embodiment, the lower guide track 29 is straight, in particular over at least the section over which the guide carriage 26 can move with guide elements.

The two guideways 28 and 29 are in particular oriented parallel to each other.

The guide carriage 26 shown here is the guide carriage on the right when the cooking appliance 1 is viewed from the front. In one embodiment, the cooking appliance 1 has a second guide carriage 26. This can preferably be constructed in the same way as the guide carriage 26. It is then a left-hand guide carriage when the cooking appliance 1 is viewed from the front. If two such guide carriages 26 are present, they can be connected with a connecting rod (not shown) that extends in the width direction.

In one embodiment, the guide carriage 26 has at least three separate guide elements 30, 31 and 32. In the embodiment in 3 There are only three guide elements 30 to 32, which are arranged on the guide carriage 26 shown here. In the exemplary embodiment, these guide elements 30 to 32 are all designed as one roller each.

They are thus rotatably mounted on a carrier 33 of the guide carriage 26. As in 3 As can be seen, the guide element 30 rests, in particular with a running surface 30a, on the upper guide track 28 from above. In the exemplary embodiment, the guide element 31 rests with a running surface 31a from below on the lower guide track 29. In the exemplary embodiment, it is further provided that a running surface 32a of the guide element 32 also rests from below on the lower guide track 29. In the exemplary embodiment shown here, two guide elements 31 and 32 are thus arranged from below on the lower guide track 29, whereas only a single guide element 30 rests from above on the upper guide track 28. As in the exemplary embodiment shown in the 3 As can be seen in the embodiment shown, these guide elements 30 to 32 are arranged offset from one another in the depth direction. In particular, in the embodiment shown here, the upper guide element 30 is in depth viewed in the direction of the window, in particular centrally, between the lower guide elements 31 and 32. The guide carriage 26 is guided on this guide part 27 with these guide elements 30 to 32. The guide part 27 with its guide tracks 28 and 29 is arranged between these three guide elements 30 to 32, viewed in the direction of height. In particular, all running surfaces 30a, 31a and 32a lie simultaneously on the respective associated guide track 28 or 29.

It is also possible that at least one guide element 30, 31, 32, viewed as a whole, is mounted on the carrier 33 in a position that can be changed. In particular, at least one guide element 30, 31, 32, viewed in the height direction, can be arranged on the carrier 33 in a spring-mounted manner.

The upper guide track 28 is arranged in particular at a distance a2 between 20 mm and 26 mm from a base 2a of the housing 2 of the cooking appliance 1 and/or the lower guide track 29 is arranged in particular at a distance a1 between 16 mm and 20 mm from a base 2a of the housing 2 of the cooking appliance 1.

In 4 the representation is in accordance with 3 shown, but here a different embodiment is shown with regard to the design of the guide carriage 26. In the 4 In the embodiment shown, two guide elements 30 and 31 are arranged with their running surfaces 30a and 31a against the upper guide track 28. Here, only one further guide element 32 is arranged with its running surface 32a against the lower guide track 29. In the embodiments in 3 and 4 The axes of rotation of the guide elements 30 to 32, which are designed here as rollers, are oriented horizontally, in particular in the width direction, i.e. here oriented perpendicular to the plane of the figure.

The interface between the door leaf 24 and the guide carriage 26, which is formed here by the coupling device 25 as an example, can also be designed with a bearing bush. A detachable decoupling between the door leaf 24 and the guide carriage 26 can also be implemented, in particular via the coupling device 25. A screw connection or a plug connection is possible here.

In all embodiments, the guide elements 30 to 32 can be designed the same. This means that in an embodiment in which the guide elements 30 to 32 are rollers, the diameters of these rollers can be the same. However, it is also possible for the at least one upper roller to be designed differently, in particular with a different diameter, to at least one lower roller.

In 5a until 5d Examples of designs for running surfaces of guide elements and shapes of guideways are shown. The sectional views shown here are not to be understood as exhaustive, but are merely intended to show some possible examples. For example, in 5a a guide element 30 with its running surface 30a is shown as an example. The guide track 28 shown here as an example is preferably laterally limited by boundary walls 33 and 34 when viewed in the width direction. As a result, a channel-like shape of the guide track 28 is formed in this cross-sectional view, which is formed perpendicular to the longitudinal axis of the guide track 28. An axis of rotation 30b, around which a guide element 30 designed as a roller can rotate, is also shown. In this embodiment, the running surface 30 is formed in a straight line in this cross-sectional view.

In 5b is a representation according to 5a shown, whereby the running surface 30a is formed in a groove-like manner. In particular, it is concavely curved. In the embodiment shown here, it is provided that the guide track 28 is formed in a hump-like manner. In particular, it has a convexly curved dome. As a result, the running surface 30a sits with its concave shape on this convexly curved guide track 28. Here too, slipping or displacement of the guide element 30 relative to the guide track 28 in the width direction is avoided or significantly limited. In 5c is an example similar to 5b The groove-like shape of the running surface 30a is different here from the embodiment in 5b . This groove-like shape is notch-like in cross-section, especially V-notch-like, so that no continuous concave curvature area is formed. In 5d A further embodiment is shown. In this case, the running surface 30a is also designed like a groove. However, here the contour is angular. A trapezoidal cross-sectional shape of the guide track 28 is preferably adapted to this. Here, too, a corresponding interlocking is realized, as is the case in 5d is shown.
