Description

[0001] One aspect of the invention relates to a cooking appliance comprising a housing and a muffle. The housing can also be referred to as the outer housing. The muffle is a separate component from the housing. The muffle is arranged within the housing. Walls of the muffle define a cooking chamber of the appliance. The cooking appliance also includes a hot air system. The hot air system has a front wall. This front wall is arranged within the cooking chamber, such that a receiving space for components of the hot air system is formed between a rear wall of the muffle and this front wall, which is offset forward, particularly in the depth direction of the cooking appliance, relative to the rear wall. The front wall has air passage openings through which hot air from this receiving space can be directed into the cooking chamber. Furthermore, the cooking appliance includes a cooking chamber divider. This cooking chamber divider is a separate component. The cooking chamber divider is, in particular, plate-like.It can be removed from and reinserted into the cooking chamber. In its final position within the cooking chamber, the divider separates the cooking chamber into a first and a second cooking area.

[0002] Such cooking appliances are known from the prior art. In these appliances, cooking chamber dividers can be positioned relatively far from the front wall of the cooking chamber. However, this restricts the division into cooking compartment zones, and the positioning of the hot air system relative to the cooking chamber divider requires corresponding space. Therefore, it may be necessary either to make the front wall smaller or to position the cooking chamber divider relatively far from the front wall.

[0003] In other cooking appliances, the oven divider can also be positioned relatively close to the front wall in its final position. However, with flat top surfaces of such oven dividers, the disadvantage arises that air openings may be largely covered by adjacent areas of the divider, making it difficult for air to escape. In particular, this can lead to an air stagnation at the interface. This can cause air to enter or be forced into the area of ​​the oven where the introduction of hot air by the convection system is undesirable.

[0004] US patent 2020 / 0309379 A1 shows an oven appliance with an upper and a lower cooking chamber, as well as a first heating element that is in direct thermal contact with the upper cooking chamber and a second heating element that is in direct thermal contact with the lower cooking chamber.

[0005] The object of the present invention is to create a cooking appliance in which, when the cooking chamber divider is positioned adjacent to a hot air system, such an air build-up is better prevented.

[0006] Further relevant prior art is known from EP 3 364 113 A1 and DE4224797C2.

[0007] This problem is solved by a cooking appliance which has the features according to claim 1.

[0008] One aspect of the invention relates to a cooking appliance comprising a housing and a muffle. The housing can also be referred to as the outer housing. The muffle is a separate component from the housing. The muffle is arranged within the housing. Walls of the muffle define a cooking chamber of the cooking appliance. The cooking appliance also includes a hot air system. The hot air system has a front wall. This front wall is arranged within the cooking chamber, such that a receiving space for components of the hot air system is formed between a rear wall of the muffle and this front wall, which is offset forward, particularly in the depth direction of the cooking appliance, relative to the rear wall. The front wall has air passage openings through which hot air generated by the hot air system can be directed from this receiving space into the cooking chamber. Furthermore, the cooking appliance includes a cooking chamber divider. This cooking chamber divider is a separate component.The oven divider is primarily plate-like in design. It can be reversibly removed from and reinserted into the oven. When the oven divider is in its final position, it divides the oven into a first oven compartment and a separate second oven compartment.

[0009] In particular, the oven divider, when viewed in the depth direction of the cooking appliance, is arranged to overlap the front wall in its final position. Additionally, or alternatively, the oven divider, when viewed in the height direction of the cooking appliance, is also arranged to overlap the front wall in its final position. On the side of the oven divider facing the front wall, an uneven flow-guiding structure is formed in an edge area of ​​the oven divider adjacent to the front wall. This structure is designed and intended to deflect the hot air entering the cooking chamber through air vents in the front wall and the air flowing towards the oven divider into the area of ​​the cooking chamber to be supplied with hot air.This uneven flow-guiding structure, when positioned directly adjacent to the oven divider and the front wall, improves the flow characteristics of the hot air exiting through the air vent. Even though the oven divider and the front wall are directly adjacent at this interface, this uneven flow-guiding structure allows the hot air to be redirected without stagnation into the area of ​​the oven that requires hot air supply. This creates a suitable air space, effectively preventing unwanted stagnation of the hot air.This uneven flow-guiding structure creates an increase in volume, particularly at this interface, compared to adjacent zones between the oven divider and the front wall. This improves the entry of hot air from the air vent into this volume, reducing stagnation and thus enabling the immediate and improved discharge of this hot air from this enlarged airspace into the rest of the oven. The flow-guiding structure further facilitates this flow of hot air into the rest of the oven. This also prevents the hot air entering through the air vent at this interface between the oven divider and the front wall from becoming trapped and thus prevents it from being forced into other areas of the oven.In particular, this improves the prevention of air accumulating at the interface of the cooking chamber divider being forced past the edge of the cooking chamber divider into the other cooking chamber area.

[0010] This improves the ability to prevent unwanted hot air from entering other cooking areas when using a hot air system, thus preventing unwanted hot air from entering other cooking areas, especially when a cooking process is also taking place there.

[0011] In one embodiment, the flow guide structure has a recess, particularly a trough-like one, at least partially in the edge region. This recess is formed on the aforementioned facing side, creating an enlarged airflow space, or rather a correspondingly larger volume, between the front wall and the facing side. Thus, this recess further distances the portion of the facing side of the cooking chamber divider that is directly opposite the front wall from it, thereby creating this enlarged airflow space. Such a specific geometric design of this facing side in the immediate interface area with the front wall enables the aforementioned advantages to a particularly high degree. Furthermore, this geometry of the flow guide structure is very simple and significantly enhances the flow characteristics.On the other hand, this design of the top or the facing side of the cooking chamber divider with the recess is also easy to implement from a manufacturing perspective.

[0012] The trough has a boundary wall. This wall is curved, at least in part. In cross-section, the boundary wall, viewed perpendicular to the longitudinal axis of the trough, is in particular concave, especially over at least 70%, and in particular over at least 80% of its length between the upper edges of the trough. Thus, it bulges away from the front wall. This advantageously creates an enlarged volume space between the front wall and this boundary wall of the trough. The air entering this volume space, in particular an enlarged air inlet chamber, then encounters this, in particular continuously curved, boundary wall, allowing for a particularly uniform and unobstructed flow. In particular, the boundary wall, viewed in cross-section, is free of corners. Viewed in cross-section, the boundary wall of the trough has no wall section that is parallel to the front wall.The front wall has, in particular, straight wall sections in its cross-section.

[0013] In one embodiment, this recess, viewed in the depth direction of the cooking appliance, overlaps the front wall. This facilitates the flow of hot air through the at least one air inlet opening into the cooking chamber, particularly into the interface area between the front wall and the cooking chamber divider. Furthermore, this positioning is also particularly advantageous for enabling a highly directed and uniform discharge of the incoming hot air from this recess, via the further flow guide structure, into the rest of the cooking chamber.

[0014] In one embodiment, the recess overlaps the front wall of the cooking appliance when viewed vertically. This further enhances the advantages mentioned above. The recess creates a longer boundary wall, extending vertically as well. This further facilitates the controlled, homogeneous, and even distribution of hot air from the recess into the cooking chamber. This also prevents undesirable turbulence or excessive stagnation of hot air within the recess itself.

[0015] In one embodiment, the recess is formed around a lower edge of the front wall. This lower edge, or rather the lower corner area, allows for a flow pattern of the hot air passing through an air vent that prevents it from accumulating or creating a constriction in the airflow chamber. This embodiment creates a gap between this lower edge and the wall of the recess, enabling a very advantageous, and in particular, uniform flow of air into the rest of the cooking chamber, thus reducing the risk of air stagnation.

[0016] In one embodiment, the upper edge of the recess, viewed in the depth direction of the cooking appliance, is positioned further forward than the rear end of the cooking chamber divider. Thus, the recess does not extend completely to the rear edge of the cooking chamber divider when viewed in the depth direction. This is a further advantageous embodiment because it prevents hot air passing through air vents in the front wall from easily and completely reaching this rear end of the cooking chamber divider and potentially being forced around this rear end and flowing into the other cooking chamber area.By extending the oven divider upwards at this rear end, or by positioning it directly adjacent to the front wall, and especially by partially abutting the outer edge of the front wall, a flow stop for the incoming hot air can be achieved. By offsetting this recess forward, the hot air can be directed more effectively into it, and the geometry and design of the recess, particularly its distance from the outer edge of the front wall, ensure that the hot air flows in the desired direction into the rest of the oven. The distance between the recess, especially its boundary wall, and the front wall is greater than the minimum distance between the rear portion of the oven divider and the front wall.

[0017] In one embodiment, the front upper edge of the cooking trough, viewed in the depth direction of the cooking appliance, is positioned higher than the rear upper edge of the trough, also viewed in the depth direction. Thus, these two upper edges, which are offset from each other in the depth direction and therefore define the end boundaries of the trough in this depth direction, are offset from each other in the height direction. This creates a geometry that, on the one hand, facilitates the improved flow of hot air from the front wall into the trough and, on the other hand, enables a particularly advantageous extraction of the incoming hot air from the trough into the rest of the cooking chamber.In particular, this also prevents undesirably strong turbulence from forming around a lower edge area of ​​the front wall, which could potentially restrict the further outflow of hot air from the trough.

[0018] In one embodiment, a front section of the trough, viewed in the depth direction, extending to the front upper edge of the trough, is formed as a flow ramp. This flow ramp is directed upwards, forming a rising, curved section of the boundary wall. This also means that this front section of the trough is continuously curved, preferably with a continuous concave curve. By extending upwards in the vertical direction with its curvature, a particularly advantageous airflow geometry is created. As in the example above, this can also be formed as a flow ramp, resulting in a particularly efficient flow and discharge of air from the trough into the rest of the cooking chamber.

[0019] In particular, this flow ramp extends from a minimum point of the trough-shaped boundary wall to the upper edge of the front trough. Vertically, the flow ramp extends from its rear end, which lies below the edge of the front wall, to a front end, which lies above the edge.

[0020] In one embodiment, the front wall is shaped like a trough. This trough shape comprises a front plate and a front wall collar. The front wall collar is arranged around one edge of the front plate. Such a front wall is inherently more stable and rigid. Therefore, it exhibits greater resistance to deformation, even under high heat. Furthermore, it advantageously allows the receiving space to be defined by this front wall collar, even at its narrow sides. In particular, it can be provided that this front wall collar, when the front wall is installed, rests against the rear wall, at least in some areas. This ensures that the receiving space is at least partially enclosed at its narrow periphery, which is defined by the depth-measured distance between the rear wall and the front wall. This prevents unwanted hot air from escaping in these areas.In particular, this makes it possible for the hot air generated in the correspondingly closed intake space to enter the cooking chamber only or essentially only through the defined and arranged light outlet openings in the front wall.

[0021] In one embodiment, the cooking chamber divider, when in its final position, overlaps the front wall collar of the front wall by at least 50%, and in particular at least 80%, in the cooking chamber in the depth direction of the cooking appliance. Thus, not only is a linear edge provided, as would be formed solely by the front panel at its edge, but a larger overlap area with the cooking chamber divider is also achieved in the depth direction through these flat strips of the front wall collar. The invention is particularly advantageous in such embodiments. This results in a larger interface area between the side of the cooking chamber divider facing the front wall and this front wall collar. It is precisely in this area that any hot air that might enter, which could be particularly disadvantageous, can accumulate and be forced around the cooking chamber divider, flowing into the other cooking chamber section.The invention avoids this in a particularly advantageous way. Because the recess also forms an enlarged air inlet space, geometrically and positionally specified by the recess, between the front wall collar and the side of the cooking chamber divider facing the front wall collar, an undesirable accumulation of the incoming hot air is particularly advantageously avoided at this interface area between the front wall collar and the cooking chamber divider.

[0022] In one embodiment, the rear upper edge of the recess (when viewed in the depth direction) is positioned at a first distance, particularly vertical when viewed in the height direction, from the front wall collar of the front wall. The front upper edge of the recess (when viewed in the depth direction) is positioned at a second distance, particularly horizontal when viewed in the depth direction, from the front panel of the front wall. In particular, the first distance is smaller than the second distance. This geometry thus enlarges or widens the airflow space, at least partially, from back to front and upwards. This facilitates a particularly advantageous entry of hot air into the recess and a particularly advantageous channeling of this hot air into the airflow space and towards the rest of the cooking chamber.

[0023] In one embodiment, at least one air passage opening is formed in the front wall collar. The invention is particularly advantageous in such an embodiment. When hot air enters through this specifically arranged air passage opening in the front wall collar, it flows downwards, in one embodiment, directly towards the oven divider. Furthermore, in this embodiment, the presence of a recess in the oven divider in the area of ​​the air passage opening located in the front wall collar provides the air inlet space.Thus, at this local point, a particularly advantageous flow of hot air towards the cooking chamber divider can occur, reducing backflow at least in the process, and, due to its design with the uneven flow-guiding structure, especially the trough, the air can be directed into the rest of the cooking chamber in a very demand-oriented manner.

[0024] In one embodiment, the recess and the air passage opening in the front wall collar are arranged to overlap each other, at least partially, when viewed in the depth direction. The resulting advantages have already been mentioned above.

[0025] In one embodiment, the at least one air opening in the front wall collar is formed with a sloped wall that projects rearward from the air opening into the receiving chamber. This ensures that the hot air in the receiving chamber is guided toward the air opening in a very specific way by this sloped wall. In particular, this sloped wall directs the hot air in the receiving chamber in a flow direction oblique to the axis of the air opening. This is such that, as the hot air passes through the air opening, it enters the recess obliquely, facing the cooking chamber. Therefore, in this embodiment, the flow direction of this hot air is not, or not primarily, perpendicular to the axis of the air opening, but rather oblique to it.This wall slope thus favors the flow of hot air through the air vent, so that the hot air passing through already has a predefined flow direction in the cooking chamber. This flow is directed diagonally into the recess and towards the cooking chamber. This flow direction is directed away from the rear end of the cooking chamber divider. This also effectively prevents hot air flowing into the recess through the air vent from reaching the rear end of the cooking chamber divider, to which the recess is slightly spaced, on the side facing the divider. This wall slope could, for example, be a bend in a cut-out section of the front wall.

[0026] The front wall can be made of metal. For example, it can be a sheet of metal, especially a sheet of steel. This makes it easy to manufacture and position the angled wall precisely, and also ensures sufficient stability against high temperatures.

[0027] In one embodiment, the cooking chamber divider extends across the entire width of the clear opening of the cooking chamber between two vertical side walls of the muffle. In particular, in one embodiment, the cooking chamber divider extends across the entire clear opening of the depth up to the front loading opening of the cooking chamber. The cooking chamber divider is preferably formed as a continuous plate. Therefore, in one embodiment, the cooking chamber divider can also be formed or designated as a partition plate.

[0028] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth", "latitude", "height", etc. indicate the positions and orientations given when the device is used and arranged as intended.

[0029] Further features of the invention can be found in the claims, the figures and the description of the figures.

[0030] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a schematic vertical section view through an embodiment of a cooking device according to the invention; Fig. 2 a front view of an embodiment of a cooking device according to the invention; Fig. 3 an enlarged view of a partial area of ​​the cooking device according to Fig. 1 and Fig. 2 ; and Fig. 4 a perspective view of an embodiment of a front wall of a hot air system of the cooking appliance.

[0031] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0032] In Fig. 1 An exemplary embodiment of a cooking appliance 1 is shown in a schematic vertical sectional view. The cooking appliance 1 can be, for example, an oven. It can be a microwave oven or a steam oven. A cooking appliance 1 that is a combined microwave oven and / or steam oven is also possible.

[0033] The cooking appliance 1 has a housing 2. This can also be referred to as the outer housing. Furthermore, the cooking appliance 1 has a muffle 3. The muffle 3 is a separate component from the housing 2. The muffle 3 is enclosed within the housing 2. The muffle 3, with its walls, defines a cooking chamber 4 of the cooking appliance 1. In the embodiment shown here, the muffle 3 has a top wall 5, a bottom wall 6, a rear wall 7, and opposing side walls 8 and 9. Fig. 2 ) on. The cooking chamber 4 is bounded by these walls 5 to 9. Thermally insulating material may be introduced, at least partially, into a space between the muffle 3 and the housing 2. The cooking appliance 1 also has a door 10. The cooking chamber 4 can be closed at the front by means of the door 10. In particular, a front loading opening 11 of the cooking chamber 4 can be closed by means of this.

[0034] The cooking appliance 1 also has a hot air system 12. The hot air system 12 is designed to generate hot air that is introduced into the cooking chamber 4. In the embodiment described here, the hot air system 12 is located in the upper region of the cooking chamber 4. The hot air system 12 has a front wall 13. This is a separate component from the muffle 3, and in particular from the rear wall 7. The front wall 13 is located in the cooking chamber 4 in the depth direction (z-direction) of the cooking appliance 1, in front of the rear wall 7. A receiving space 14 is defined by the rear wall 7 and the front wall 13. A heating element 15 and a fan 16 of the hot air system 13, for example, can be arranged in this receiving space 14. The heat generated by the radiator 15, or the air thereby heated in the receiving chamber 14, is introduced into the cooking chamber 4 by the blower 16 through air passage openings 17 in the front wall 13.

[0035] In one embodiment, this front wall 13 has a front panel 18. Furthermore, a front wall collar 19 is formed along the edge of this front panel 18 and extends around its perimeter. As a result, the front wall 13 in this embodiment has a trough shape. The receiving space 14 is thus also closed, or substantially closed, at the depth-measured distance between the front panel 18 and the rear wall 7 by this front wall collar 19.

[0036] In one embodiment, it can be provided that at least one further air passage opening 20 is formed on a lower section of the front wall collar 19 when viewed in the vertical direction (y-direction).

[0037] Furthermore, the cooking appliance 1 has a cooking chamber divider 21. The cooking chamber divider 21 is a separate component. Here, the cooking chamber divider 21 is a plate-shaped partition. The cooking chamber divider 21 is preferably completely uninterrupted. It can be inserted into the cooking chamber 4 at a specific and defined insertion level in the vertical direction. The cooking chamber divider 21 is designed to separate the entire continuous cooking chamber 4 into an upper cooking chamber area 4a and a lower cooking chamber area 4b. These cooking chamber areas 4a and 4b are then each sub-areas of the entire cooking chamber 4. They are dimensioned so that food can be placed in each of the cooking chamber areas 4a and 4b for preparation. The cooking chamber divider 21 is dimensioned in the width direction (x-direction) as shown in Fig. 2 The cooking chamber divider 21 is shown, in particular essentially across the entire clear width between the vertical side walls 8 and 9. In the depth direction, the cooking chamber divider 21 is measured in particular essentially across the entire depth, especially between the rear wall 7 and the loading opening 11. As can be seen, in the exemplary embodiment, the hot air system 13 is positioned in the upper area such that it can be used for the entire cooking chamber 4 when the cooking chamber divider 21 is removed. When the cooking chamber divider 21 is inserted, which is in particular when it is arranged in its inserted end position in the cooking chamber 4, the hot air system 12 is only intended for the upper cooking chamber area 4a.

[0038] It's like in Fig. 4 It can also be seen that the cooking chamber divider 21 is arranged in its final position directly adjacent to the front wall 12.

[0039] The cooking chamber divider 21, when viewed in the depth direction of the cooking appliance 1, is arranged overlapping the front wall 12, in particular the front wall collar 19, in its final position. In one embodiment, the cooking chamber divider 21, when viewed in the height direction of the cooking appliance 1, is arranged overlapping this front wall 12, in particular the front panel 18. On the side 22 of the cooking chamber divider 21 facing the front wall 12, an uneven flow-guiding structure 24 is formed in an edge region 23 of the cooking chamber divider 21 adjacent to the front wall 12. It is, in particular, integrated into the cooking chamber divider 21, and especially manufactured in one piece with it.

[0040] In particular, the uneven flow guide structure 24 is formed with a boundary wall that is free of corners in cross-section. In the lateral direction, the flow guide structure 24 extends, in particular, along the length in which the air passage openings 20 are arranged. The flow guide structure 24 and the air passage openings 20 are therefore arranged to overlap in the lateral direction. At the ends of the cooking chamber divider 21 that are opposite each other in the lateral direction, the flow guide structure 24, in particular a recess 25, can be closed laterally.

[0041] This uneven flow guide structure 24 is designed to redirect the hot air entering the cooking chamber 4, here the cooking chamber area 4a, through air passage openings, in particular the air passage opening 20, and the hot air flowing towards the cooking chamber divider 21 into the cooking chamber 3, here in particular into the cooking chamber area 4a assigned to the hot air system 13.

[0042] As in Fig. 1 As can already be seen, the flow guide structure 24 in the edge region 23 is formed, at least partially, as a channel-like trough 25 on the side 22 facing the front wall 12. This creates an enlarged air inlet space 26 between the front wall 12, in particular the front wall collar 19 facing the cooking chamber divider 21, and this edge region 23.

[0043] In one embodiment, this recess 25 is arranged overlapping with the front wall 12, in particular the front wall collar 19, when viewed in the depth direction. In another embodiment, this recess 25 is arranged overlapping with the front wall 12, in particular the front panel 18, when viewed in the height direction. As further described in Fig. 1 As can also be seen, in one embodiment this recess 25 is formed around a lower edge region 27 of the front wall 12. In particular, the recess 25 is thus formed around a lower corner region that is formed between this lower section of the front wall collar 19 and the front panel 18.

[0044] In one embodiment, a rear end 28 of the cooking chamber divider 21 is arranged abutting the rear wall 7 or minimally spaced from it. Furthermore, in one embodiment, it is provided that a rear upper edge 29 of the recess, viewed in the depth direction ( Fig. 3 ) viewed in the direction of depth, it is offset forwards to this rear end 28 of the cooking chamber divider 21.

[0045] Furthermore, the front upper edge 30 of the trough 25, viewed in the direction of depth, is positioned higher in the direction of height than the rear upper edge 29 of the trough 25, viewed in the direction of depth.

[0046] Furthermore, it can also be seen that a forward trough area 31 of the trough 25, viewed in the direction of depth, up to the forward upper edge 30 of the trough 25, is formed as a flow ramp, in particular continuously oriented upwards.

[0047] As in Fig. 1 and in the enlarged view of the partial section of the interface between the front wall 12 and the edge area 23 in Fig. 3 As can be seen, the oven compartment divider 21 is arranged in the final position overlapping the front wall collar 19 by at least 50%, and in particular by at least 80%, in the depth direction.

[0048] A rear upper edge 29 of the trough 25, viewed in the depth direction, has a first distance a1, viewed in the height direction, to the front wall collar 20. A front upper edge 30 of the trough 25, viewed in the depth direction, has a second distance a2, viewed in the depth direction, to the front plate 18. In particular, the first distance a1 is smaller than the second distance a2. This distance a1 is preferably dimensioned to a minimum, so that hot air L ( Fig. 3 ), which flows downwards from the receiving chamber 14 through at least one air passage opening 20, cannot be pushed backwards to the rear end 28 or substantially not, and can flow undesirably downwards around the rear end 28 into the further cooking chamber area 4b.

[0049] As in Fig. 3 As can also be seen, this rear upper edge 29 of the recess is positioned forwards relative to this rear end 28 when viewed in the depth direction. This creates a partial area of ​​the cooking chamber divider 21 at this rear end 28, which, in the end position of the cooking chamber divider 21, is located directly adjacent to the front wall collar 19. In one embodiment, this rear upper edge 29 of the recess, viewed in the depth direction, overlaps the clear width of the air passage opening 20. In particular, it can be provided that this rear upper edge 29 of the recess is located at the same or substantially the same depth position as a rear end or a rear boundary wall of the air passage opening 20. Thus, viewed in the depth direction, the air passage opening 20 is completely or substantially completely overlapping with the recess 25.This trough 25 extends in the direction of depth between the two aforementioned trough upper edges 29 and 30.

[0050] As in Fig. 3 As can also be seen, the recess 25 widens towards the front in the depth direction at its distance from the front wall 12. Particularly around the lower edge region 27, or rather the corner region of this preferably trough-shaped front wall 12, a particularly advantageous flow behavior of the hot air L is therefore possible. In one embodiment, the recess 25 is limited in width at the opposite end sides of the cooking chamber divider 21. It is therefore a recess 25 that is closed at its edges in the width direction. In this respect, Fig. 3 For example, a side boundary wall 32 can be seen.

[0051] In Fig. 3 Furthermore, one embodiment shows that a wall slope 33 is present. This slope extends into the receiving chamber 14 and ends directly at the opening of the air passage 20. This wall slope 33 is oriented such that the hot air I exits the receiving chamber 14 with a flow direction that is inclined relative to the vertical axis of the air passage 20. This backward and upward inclined wall slope 33 thus defines a flow direction for the hot air L, causing it to enter the recess 25 at an angle, and consequently, the cooking chamber area 4a at an angle. This also effectively prevents the hot air L from flowing backward toward the rear end 28.Furthermore, this flow direction, in conjunction with the concave shape of the boundary wall of the trough 25, ensures a very uniform distribution of the hot air within the trough 25 towards the trough area 31, which serves as a flow ramp. This flow ramp also makes it particularly advantageous to direct the hot air I further into the remaining cooking chamber area 4a.

[0052] Furthermore, also in Fig. 3 As can be seen, the boundary wall of the recess 25 is U-shaped. In cross-section, the boundary wall extends between the rear upper edge 29 and the front upper edge 30 of the recess. In the area where the boundary wall overlaps the air passage opening 20, the recess 25 curves concavely downwards away from the air passage opening 20. This allows for an advantageous flow of air L into the recess 25. Viewed in the positive depth direction forwards, in one embodiment, the boundary wall of the recess 25 only rises again in a concave curve after the front plate 18.

[0053] In Fig. 2 The cooking appliance 1 is shown in a front view. The width of the cooking chamber divider 21 can be seen here.
