Description

Technical Field

[0001] The present invention relates to a cooking appliance having a door for enclosing a cooking space and having a housing in which a storage space is constructed, the door being able to sink into the storage space, wherein a guide member is arranged in the storage space, and a guide rail for a guide slider of the cooking appliance is constructed at the guide member to guide the sinking movement of the door into the storage space. Background Technology

[0002] Cooking appliances with a sinkable door are known from DE 10 2018 201 950 A1 and DE 10 2020 208 891 A1, wherein the door is coupled to a guide slider, which is guided in a guide groove by means of rollers.

[0003] Furthermore, a cooking appliance with a retractable door is known from DE 10 2015 226 009 A1. There, the storage space for the door is also defined by lateral, vertical, and particularly plate-like sidewalls. Guide rails for sliding sliders or guide sliders are also constructed in these sidewalls, which function as technical components. In this design, the guide rails are constructed very low within the technical component when viewed along the height of the cooking appliance and therefore also along the height of the technical component. This allows for a specific sequence of door movement. Specifically, in this design, the front and rear ends of the guide rails are constructed almost immediately adjacent to the lower edge of the technical component. Therefore, the door is positioned very low both at the start and end of movement.

[0004] The sinkability of relatively wide doors is limited by this type of design because the structural space is restricted not only in width but also in height. Summary of the Invention

[0005] The object of this invention is to provide a cooking appliance with a retractable door, wherein the guidance of the guide slider is improved. Therefore, it should also be possible to provide a solution that improves flexibility in using different doors.

[0006] This objective is achieved by a cooking appliance having the features of claim 1.

[0007] This invention relates to a cooking appliance having a door for enclosing a cooking space. The cooking appliance further has a housing in which a storage space is constructed. The door is capable of sinking into this storage space. The storage space is a space separate from the cooking space of the cooking appliance. Food for cooking can be introduced into the cooking space. A guide member is arranged in the storage space, at which a guide rail for a guide slider of the cooking appliance is constructed to guide the sinking movement of the door into the storage space.

[0008] The guide component has a first upper guide rail when viewed along the height direction of the cooking appliance. The guide component also has a second lower guide rail, separate from the first upper guide rail and viewed along the height direction. The guide slider has at least three separate guide elements, which simultaneously abut against both guide rails to guide the guide slider during movement. At least one guide element is arranged to rest on the upper guide rail from above when viewed along the height direction. At least one additional guide element abuts against the lower guide rail from below when viewed along the height direction. This arrangement provides particularly advantageous and improved guidance from the door into or out of the storage space. In particular, it also enables a very compact guide system, thus saving space requirements along the height direction. This is also advantageous because the cooking space of the cooking appliance can be designed to be increased while maintaining the same dimensions along the height direction. Furthermore, the guide slider (which is coupled to both guide rails from above and below on both sides when viewed along the height direction using guide elements) allows for seamless guiding movement. This means that the guide slider can guide more precisely (because of minimized tolerances) and can also better absorb the forces and peak forces acting on the guide slider and guide elements when the door moves into or out of the storage space. Through a specific number and arrangement of guide elements and specific coupling with the aforementioned guide rails, the guide components can also be designed to be lower, especially in the height direction.

[0009] In one embodiment, at least one guide element can be a roller. It is feasible that all guide elements are formed of rollers. This enables particularly uniform and smooth movement of the guide slider along the guide rail.

[0010] In other embodiments, at least one guide element can be a sliding bearing. It is feasible for all guide elements to be constructed as sliding bearings. In such embodiments, the guide elements can be designed very space-efficiently and compactly. Thus, the structure of the guide slider is minimized, particularly along the height direction. The sliding bearing is arranged at the guide slider especially where there is no possibility of its own relative movement.

[0011] In one embodiment, two guide elements abut against one of two guide rails. At least one additional guide element abuts against the other guide rail. This additional guide element can be positioned between the two other guide elements when viewed along the depth direction of the cooking appliance. A mechanically particularly stable placement at the two guide rails is achieved through such an offset of the three guide elements relative to each other in a specific spatial direction. This effectively prevents tilting movement of the guide slider about an axis oriented along the width direction of the cooking appliance. Consequently, the abutment of the guide elements at the respective guide rails can also be designed to be more uniform. This also allows for clamp-free and non-expanding movement of the guide slider at the guide component.

[0012] In one embodiment, two guide elements are specified to abut against the upper guide rail from above. A third, additional guide element then abuts against the lower guide rail from below.

[0013] In other embodiments, the guide element abuts against the upper guide rail from above, and two additional guide elements abut against the lower guide rail from below.

[0014] In other embodiments, four separate guide elements may be arranged at the guide slider. In such embodiments, preferably two guide elements are placed on the upper guide rail from above, and two additional guide elements abut against the lower guide rail from below.

[0015] In such an embodiment, viewed along the depth direction, two front guide elements (one abutting against the upper guide rail and the other abutting against the lower guide rail) can be arranged at the same depth position. Additionally or alternatively, it can be specified that two additional rear guide elements (one rear guide element placed above on the upper guide rail and the other rear guide element abutting against the lower guide rail) can be arranged at the same depth position.

[0016] In one embodiment, the lower guide rail is constructed in a straight line. This lower guide rail extends horizontally along the depth direction of the cooking appliance. Such a straight guide rail requires almost no space along the height direction because it has no curved or bent sections. This further improves the space-saving design when viewed along the height direction.

[0017] In one embodiment, the upper guide rail is constructed in a straight line. This upper guide rail extends particularly horizontally along the depth direction of the cooking appliance. This also allows for an advantage in terms of a compact structure along the height direction. This also advantageously contributes to reducing storage space in terms of height and thus increasing cooking space.

[0018] In one embodiment, the guide member can be constructed in a rod-like shape. This guide member can extend along its longitudinal axis in the depth direction of the cooking appliance. In such an embodiment, the upper side, particularly the top wall, of the guide member can form an upper guide rail. The lower side or bottom side of the guide member can form a lower guide rail. The rod-like or beam-like guide member can be solidly designed. If the guide member is constructed in a rod-like or beam-like shape, it has a very low structural height along the height direction. This also allows the guide elements of the guide slider to be spaced apart along the height direction, such that the rod-like guide member is arranged between them. This also supports the compact structure of the guiding system.

[0019] In principle, it can be specified that, viewed along the height direction, the guide component is arranged between at least one upper guide element and at least one lower guide element using its guide rails. This type of sandwich structure, having a single guide component preferably for the guide slider (which is located between these guide elements), particularly supports the advantages mentioned above regarding compact structure, mechanical stability, and smooth guidance.

[0020] However, it is also feasible to construct the guide components in two pieces. In this regard, the first guide element can have an upper guide rail, and the second guide element can have a lower guide rail. In such an embodiment, the guide elements can also be arranged spaced apart from each other when viewed in the height direction.

[0021] In one embodiment, the guide slider is coupled to the door using a hinge device of the cooking appliance. This hinge device supports the pivoting movement of the door when it is moved into and out of the storage space, so that the pivoting movement can be performed independently of the sliding movement of the guide slider. Specifically, the hinge device, viewed as a whole, can be positioned fixedly within the housing of the cooking appliance. In particular, it can be arranged at the bottom structural component of the housing. Preferably, the hinge device has its own guide component, such as a roller. In one embodiment, this guide component can be embedded in a guide groove, such as a guide channel, laterally constructed at the door. Thus, the door, especially the door panel, can move relative to the hinge device and is guided in movement by this embedded guide element of the hinge device. Alternatively, the door, especially the door panel, may have a coupling device in a lower portion. This coupling device is configured for coupling with the guide slider. In particular, this hinged coupling is permanently constructed so that the door panel can move relative to the guide slider, and also pivot. Specifically, this coupling hinge grounding structure between the coupling device and the guide slider is specified.

[0022] In one embodiment, at least one guide element, viewed as a whole, is variably supported in position at a bracket of the guide slider. This allows the guide element to be in particularly advantageous continuous contact with the guide rail. Tolerances can then be compensated for by changes in the position of the guide element at the bracket. In another embodiment, at least one guide element can be arranged at the bracket in a spring-supported manner. This allows for automatic position changes through loading caused by the spring force of the guide element. This results in a particularly advantageous, robust system that is very rapid in terms of position changes.

[0023] In one embodiment, at least one guide rail is constructed in a groove-like shape. This allows the guide rail boundary to be constructed perpendicular to its longitudinal axis. This restricts and, in particular, avoids undesirable movement of the guide element perpendicular to the longitudinal axis of the guide rail. This achieves particularly straight guidance of the guide element within the guide rail, especially along the depth direction.

[0024] In one embodiment, at least one guide rail is constructed in a raised shape when viewed in cross-section and therefore perpendicular to its longitudinal axis. Specifically, the guide rail can be convexly curved or trapezoidally designed. This shape of the guide rail also prevents undesirable slippage of the guiding element relative to the guide rail in the width direction. This shape of the guide rail also achieves particularly straight guidance of the guiding element at the guide rail.

[0025] In one embodiment, the working surface of the guide element has a groove shape, and the raised area of ​​the guide rail is embedded in the groove shape. This complementary design of the working surface of the guide element on one hand and the working surface of the guide rail on the other hand supports the advantages mentioned above to a particular degree.

[0026] In one embodiment, the guide rails are arranged at a distance between 20 mm and 26 mm from the bottom of the cooking appliance housing when viewed along the height direction of the cooking appliance. As an additional or alternative solution, in one embodiment, the lower guide rail is arranged at a distance between 16 mm and 20 mm from the bottom of the cooking appliance housing when viewed along the height direction of the cooking appliance. The upper guide rail is always positioned higher than the lower guide rail. This positioning allows the guide rails to be displaced downwards as much as possible, while still enabling unrestricted movement of the guiding elements at the guide rails. Thus, movement of the door into or out of the storage space is unaffected. Nevertheless, this also advantageously supports the ability to reduce the storage space along the height direction and therefore increase the cooking space along the height direction.

[0027] Preferably, guide sliders and guide components are constructed at opposite ends when viewed along the width direction of the cooking appliance. The two guide sliders and / or two guide components can be constructed identically. In particular, the explanations and embodiments mentioned above apply to these two guide sliders. The coupling device mentioned above can also be coupled to the two guide sliders, especially to the connecting rod that connects the two guide sliders.

[0028] The guide sliders, constructed on opposite sides, are preferably connected to the connecting rod, thereby maintaining their position relative to each other and preventing tilting or twisting relative to each other in terms of movement. This positional coupling between the guide sliders enables shock-free and uniform movement along the guide rail at the guide member. The door is advantageously connected to the guide slider at its lower end, particularly rotatably. The guide slider is a separate component from the hinge device. The guide slider is preferably connected to the door in a motion-coupled manner, wherein a rotation axis is constructed at the connection point, about which the door can then twist relative to the guide slider. In contrast, the hinge device, having the rollers described above, enables not only relative movement about rotation relative to each other, but also relative sliding movement between the door and the hinge arm through the guide grooves or guide channels already mentioned, also constructed on the side edges and located in the door.

[0029] In an advantageous embodiment, the storage space is specified to have a net width of less than or equal to 45 mm, particularly between 40 mm and 44 mm, at least at the entrance along the height direction. Preferably, this net width is constructed within at least 50%, preferably at least 80%, and particularly at least 90% of the depth of the storage space as measured along the depth direction, when viewed along the height direction.

[0030] This type of design allows for a particularly compact storage space, thus providing maximum cooking space. If the cooking appliance's casing has a common standard size, this compact storage maximizes the cooking area. Nevertheless, it still allows for easy access into or out of the storage space through a wide doorway.

[0031] In an advantageous embodiment, the door is specified to have a thickness between 35 mm and 45 mm, particularly between 38 mm and 42 mm, and preferably 40 mm. It is also feasible in this type of design for the door to have a multi-panel assembly with at least three panels, wherein a front panel, an inner panel, and at least one intermediate panel can be provided. The panels are oriented parallel to each other and are plate-like elements, particularly made of true glass. With multiple door panels, particularly at least four such separate panels, the cooking appliance can also be constructed to have a pyrolysis function.

[0032] In this type of design (where the door has the advantageous thickness mentioned above, and the storage space has the advantageous height dimension mentioned above, where the thickness is always less than the height dimension of the storage space), it is possible to move the relatively thick door into the storage space, which is only slightly higher. Through the aforementioned mechanical structure, it is possible to achieve the corresponding door movement, either in or out, even though the storage space is only slightly higher than the door's thickness. Specifically, this is achieved by the following: during the pivoting motion, especially from the closed position to the horizontally open position, the door does not move into the storage space or only slightly, and the main inward movement occurs from the horizontally open position, thus the linear movement of the door into the storage space occurs essentially after the pivoting motion.

[0033] In an advantageous embodiment, it can be additionally or alternatively specified that the door, viewed from its outer side in the width direction, has a width between 530 mm and 545 mm, particularly between 535 mm and 540 mm. Such a wide door allows for improved clearance design. Specifically, this improves clearance relative to adjacent components, such as, for example, the front slats, which are constructed as visible members or external parts of the cooking appliance on the front side. In particular, this clearance can be set relatively small. In this respect, the aforementioned design of the door with its specific width allows for a unified front appearance between cooking appliance variants (one having only a flip-up door, the other having a recessable door as explained above). In the closed state of the door, a unified appearance can then be provided in both cooking appliance variants.

[0034] The terms "above", "below", "in front", "behind", "horizontally", "vertically", "depth", "width", and "height" are used to describe the position and orientation given to an observer who is using and arranging the appliance in accordance with regulations and who is then standing in front of the appliance and looking in the direction of the appliance.

[0035] Further features of the invention are derived from the claims, drawings, and description of the drawings. The features and combinations of features mentioned above in the specification, as well as those mentioned below in the description of the drawings and / or shown separately in the drawings, can be used not only in the separately described combinations but also in other combinations without departing from the framework of the invention. Therefore, the following embodiments can also be considered as included and disclosed as embodiments of the invention, which are not explicitly shown and illustrated in the drawings but can be derived and produced by separate combinations of features from the illustrated embodiments. Therefore, embodiments and combinations of features that do not possess all the features of the initially stated independent claims can also be considered as disclosed.

[0036] Embodiments of the present invention will now be explained in more detail with reference to the schematic accompanying drawings. Wherein: Figure 1 A perspective view of an embodiment of a cooking appliance according to the present invention is shown. Figure 2 It shows according to Figure 1 A schematic vertical cross-sectional view of a cooking appliance. Figure 3 It shows according to Figure 1 A schematic side view of a portion of the door area of ​​a cooking appliance, which has a specific design of guide sliders arranged at the guide components of the cooking appliance. Figure 4 It shows according to Figure 3 In and Figure 3 Diagrams illustrating different embodiments, and Figures 5a to 5d An exemplary cross-sectional view is shown, illustrating an embodiment of the shape of the roller guiding the slider and the shape of the guide rail. Detailed Implementation

[0037] In the accompanying drawings, elements that are identical or have the same function are given the same reference numerals.

[0038] exist Figure 1 The diagram illustrates a household appliance 1, configured as an oven, in a schematic perspective view. Appliance 1 has a housing 2 within which a cooking space defined by a muffle oven (not shown) is constructed. Food for cooking can be introduced into the cooking space. The cooking space can be closed off at the front by a door 3. Figure 1 The door is shown in its closed end position. A handle 4 is constructed on the front side of the door 3.

[0039] In addition, the oven has an operating device 5, which, by way of example, has a display unit 6 and operating elements 7 and 8 in terms of position and display.

[0040] The housing 2 can have walls 9, 10, 11 and 12.

[0041] Door 3 can be pushed into or sunk into housing 2 in its lower region 13, and door 3 can be pushed into or sunk into housing 2 from Figure 1 This is the case when the closed end position shown is transferred to the fully open and sunken end position. The door 3 is then arranged in the free space of the housing 2 in a sunken manner, wherein a storage space 14 is constructed through the free space and is arranged below the cooking space and separated from the cooking space by a corresponding separating wall.

[0042] Door 3 is connected to a door hinge, which is exemplarily shown and labeled as an example of hinge devices 15 and 16, and is pivotable by the door hinge and can be moved into and out of the aforementioned storage space 14.

[0043] exist Figure 2 The diagram shows a vertical cross-sectional view (section plane yz plane) of cooking appliance 1. The cooking space 17 defined by the mentioned muffle oven can be identified here.

[0044] It can be identified here that the storage space 14 has a net width w, which is measured along the height direction (y direction) and is particularly between 40 mm and 44 mm, preferably between 42 mm and 43 mm.

[0045] The thickness d of door 3 ( Figure 2 The preferred size is between 38 mm and 42 mm, especially 40 mm.

[0046] The measurement along the width direction (x direction) of door 3, such as Figure 1 The width b indicated therein is preferably between 530 mm and 545 mm, and more particularly between 535 mm and 540 mm.

[0047] The front panel 3a, inner panel 3b, and middle panel 3c of door 3 are also shown.

[0048] For example, a view shown along the negative x-direction. Figure 3As shown, the hinge device 15 can have a hinge housing 18. This hinge housing can be fixedly arranged within the housing 2 as a whole. The hinge device 15 further has a bearing unit 19 with a bearing bracket 20. At least one guide element 21, here a roller, is rotatably supported at the bearing bracket 20. The guide element 21 is embedded in a groove-shaped guide channel 22, which is constructed at the side edge 23 of the door 3 and extends in the height direction when the door 3 is closed. Therefore, the guide element 21 is guided in the guide channel 22, which is laterally open outwards in the width direction.

[0049] The guide groove 22 is specifically constructed at the door panel 24 of the door 3. The door panel 24 is a plate-shaped front element of the door 3.

[0050] The door 3 also has a coupling device 25. Using this coupling device 25, the door panel 24 is coupled to at least one guide slider 26 of the door 3. Specifically, guide sliders 26 are arranged on opposite sides along the width direction. In particular, a hinged connection is constructed here, so that the door panel 3 can pivot hingedly relative to, and especially about, an axis oriented along the width direction (x-direction) while coupled to the guide sliders 26.

[0051] The cooking utensil 1 also has guide members 27. The guide members 27 are arranged in the storage space 14. In particular, guide members 27 are arranged on opposite sides along the width direction.

[0052] The guide slider 26 is guided at the guide member 27. The guide member 27 can be constructed in a rod-like or beam-like manner. The guide member extends along its longitudinal axis in the depth direction (z-direction) of the cooking appliance 1. The guide member is particularly disposed at the side wall, which laterally defines the storage space 14. In the illustrated embodiment, the guide member 27 has an upper guide rail 28 viewed in the height direction (y-direction) of the cooking appliance 1. In one embodiment, the upper guide rail 28 is straight, particularly within at least the following sections, along which the guide slider 26 can move, particularly using a guide element. Furthermore, the guide member 27 has a lower guide rail 29 viewed in the height direction. The lower guide rail is disposed below the upper guide rail 28. In one embodiment, the lower guide rail 29 is straight, particularly within at least the following sections, along which the guide slider 26 can move, using a guide element.

[0053] The two guide rails 28 and 29 are oriented in particular to be parallel to each other.

[0054] The guide slider 26 shown here is the guide slider on the right side when viewing the cooking appliance 1 from the front. In one embodiment, the cooking appliance 1 has a second guide slider 26. This second guide slider can preferably be constructed based on the guide slider 26. This second guide slider is then the guide slider on the left side when viewing the cooking appliance 1 from the front. If two such guide sliders 26 are present, they can be connected using a connecting rod (not shown) extending in the width direction.

[0055] In one embodiment, the guide slider 26 has at least three separate guide elements 30, 31, and 32. Figure 3 In this embodiment, only these three guide elements 30 to 32 are present, and they are arranged at the guide slider 26 shown. In this embodiment, all of these guide elements 30 to 32 are configured as rollers.

[0056] Therefore, these guide elements are rotatably supported at the bracket 33 of the guide slider 26. (As in...) Figure 3 As can be identified, guide element 30 is positioned above the upper guide rail 28 with its working surface 30a. In an embodiment, guide element 31 abuts against the lower guide rail 29 from below with its working surface 31a. In another embodiment, guide element 32 is also provided with its working surface 32a abutting against the lower guide rail 29 from below. In the embodiment shown here, therefore, both guide elements 31 and 32 are arranged to abut against the lower guide rail 29 from below, while only a single guide element 30 abuts against the upper guide rail 28 from above. As in Figure 3 As can be identified in the illustrated embodiment, these guide elements 30 to 32 are arranged in a staggered manner relative to each other along the depth direction. In particular, in the embodiment shown here, the upper guide element 30 is positioned particularly centrally between the lower guide elements 31 and 32 when viewed along the depth direction. The guide slider 26 is guided at the guide member 27 using these guide elements 30 to 32. The guide member 27 is arranged between these three guide elements 30 to 32 when viewed along the height direction using its guide rails 28 and 29. In particular, all the working surfaces 30a, 31a, and 32a simultaneously abut against their respective associated guide rails 28 or 29.

[0057] Alternatively, at least one guide element 30, 31, 32 may be supported in a positional manner at the bracket 33 when viewed as a whole. In particular, at least one guide element 30, 31, 32 may be arranged in a resiliently supported manner at the bracket 33 when viewed in the height direction.

[0058] The upper guide rail 28 is arranged at a distance a2 between 20 mm and 26 mm from the bottom 2a of the housing 2 of the cooking appliance 1, and / or the lower guide rail 29 is arranged at a distance a1 between 16 mm and 20 mm from the bottom 2a of the housing 2 of the cooking appliance 1.

[0059] exist Figure 4 The text shows the following: Figure 3 The diagram shows, however, different embodiments of the design for the guide slider 26. Figure 4 In the illustrated embodiment, two guide elements 30 and 31 abut against the upper guide rail 28 with their working surfaces 30a and 31a. Here, only one additional guide element 32 is then arranged to abut against the lower guide rail 29 with its working surface 32a. Figure 3 and Figure 4 In this embodiment, the rotation axis of the guide elements 30 to 32 of the roller is configured to be horizontal, particularly oriented in the width direction, i.e., perpendicular to the plane of the drawing.

[0060] The interface between the door panel 24 and the guide slider 26, exemplarily formed by the coupling device 25, can also be implemented using a bearing sleeve. In particular, the coupling device 25 also enables the releasable decoupling of the door panel 24 and the guide slider 26. This can be achieved through threaded or plug-in connections.

[0061] In all embodiments, guide elements 30 to 32 can be constructed identically. This means that in embodiments where guide elements 30 to 32 are rollers, these rollers can have the same diameter. However, it is also possible for at least one upper roller to be constructed differently from at least one lower roller, particularly having different diameters.

[0062] exist Figures 5a to 5d The diagram illustrates embodiments of the shapes of the functional surfaces of the guiding element and the guide rails. The cross-sectional views shown here should not be taken as definitive interpretations, but rather represent some feasible examples. Therefore, in Figure 5a The guide element 30, having its working surface 30a, is illustrated exemplarily here. The guide rail 28, exemplarily shown here, is preferably defined laterally by boundary walls 33 and 34 when viewed along its width. Thus, a groove-like shape is formed in the cross-sectional view perpendicular to the longitudinal axis of the guide rail 28. A rotation axis 30b is also drawn, about which the guide element 30, configured as a roller, can rotate. In this embodiment, the working surface 30 is constructed linearly in this cross-sectional view.

[0063] exist Figure 5b The text shows the data based on... Figure 5aThe diagram shows that the working surface 30a is grooved. This working surface is particularly concave and curved. In the embodiment shown here, the guide rail 28 is convexly shaped. This guide rail particularly has a convexly curved arched structure. Thus, the working surface 30a, with its concave shape, rests on the convexly curved guide rail 28. Therefore, slippage or offset of the guide element 30 relative to the guide rail 28 in the width direction is particularly avoided or significantly limited. Figure 5c The image shows something similar to Figure 5b The embodiment. The groove shape of the working surface 30a is here similar to... Figure 5b The embodiments described in this paper differ from those in the present invention. The groove shape here is notched in cross-section, particularly V-shaped, thus not forming a continuous concave curved region. Figure 5d Another embodiment is shown. In this embodiment, the working surface 30a is also constructed in a groove shape. However, here the profile is angular. Preferably, the trapezoidal cross-sectional shape of the guide rail 28 is adapted to this profile. Here, corresponding interlocking is thus achieved, as in Figure 5d As shown.
