Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a plate and a cooking utensil. Background Technology

[0002] Currently, in cooking appliances with microwave generators, the inner wall of the cooking cavity is composed of a flat top plate, a back plate, two side plates, and a door. Therefore, when cooking food with microwaves, the reflection of microwaves by each flat plate of the cooking cavity is basically fixed. This configuration leads to uneven distribution of microwaves in the cooking cavity, which in turn affects the uniformity of heating of the food. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model provides a plate.

[0005] A second aspect of this utility model also provides a cooking utensil.

[0006] In view of the above, the first aspect of this utility model proposes a plate body for use in a cooking appliance, the cooking appliance including a microwave generating unit and a cooking cavity, the microwave generating unit for feeding microwaves into the cooking cavity, a portion of the surface of the plate body being the inner wall surface of the cooking cavity, the plate body including: a substrate, the substrate having a first texture group and a second texture group, the first texture group and the second texture group being located on the side of the substrate facing the cooking cavity, the first texture group including a plurality of first textures, the second texture group including a plurality of second textures; wherein, the plurality of first textures and the plurality of second textures are intersected to enclose a plurality of reflective surfaces, the reflective surfaces being used to reflect microwaves emitted by the microwave generating unit.

[0007] The plate provided by this utility model is used in a cooking appliance, which includes a microwave generator and a cooking cavity. A portion of the plate's surface forms the inner wall of the cooking cavity. The plate includes a substrate. A first texture group and a second texture group are provided on the side of the substrate facing the cooking cavity. The first texture group includes multiple first textures, and the second texture group includes multiple second textures. The multiple first and second textures are interwoven, thus forming multiple reflective surfaces on the side of the substrate that forms the inner wall of the cooking cavity. In this way, after the microwave generator feeds microwaves into the cooking cavity, the reflective surfaces can reflect the microwaves multiple times, increasing the number of microwave reflections and making the microwave distribution within the cooking cavity more uniform. This improves the temperature uniformity when microwaves heat food, thereby enhancing the cooking effect and shortening the cooking time.

[0008] In some embodiments, the internal protrusion facing the cooking cavity may be reflected or the side facing away from the cooking cavity may be recessed.

[0009] In this embodiment, the reflective surface is either protruding inside the cooking cavity or recessed on the side away from the cooking cavity, thereby reflecting microwaves in different directions, improving the microwave uniformity within the cooking cavity, and thus improving the uniformity of heating of the food.

[0010] In some embodiments, the cross-section of the reflective surface is optionally arc-shaped; and / or both the first texture and the second texture are arc-shaped.

[0011] In this embodiment, the cross-section of the reflective surface is arc-shaped. This increases the surface area, improving microwave reflection. Furthermore, the arc shape alters the angle of the reflected microwaves, resulting in more uniform microwave distribution within the cooking cavity and thus improving the cooking effect on the food, ensuring more even heating. Optionally, both the first and second textures are arc-shaped. This arrangement increases the length of both textures, thereby increasing the number of intersections and ultimately the number of reflective surfaces. Additionally, the arc-shaped edges of the reflective surface increase its overall surface area, which in turn facilitates more microwave reflections.

[0012] In some embodiments, the first texture and the second texture are optionally bent in opposite directions.

[0013] In this embodiment, the first and second textures are bent in opposite directions, which increases the length of the first and second textures, thereby increasing the number of reflective surfaces and improving the number of microwave reflections. At the same time, it also makes the design of the plate more aesthetically pleasing.

[0014] In some embodiments, optionally, the first texture includes a first end and a second end, the first ends of a plurality of first textures are located at the bottom of the substrate along the height direction of the cooking appliance, and the first ends of the plurality of first textures are sequentially spaced at the bottom of the substrate, and the plurality of first textures are radiating from the first end to the second end; the second texture includes a third end and a fourth end, the third ends of a plurality of second textures are located at the bottom of the substrate along the height direction of the cooking appliance, and the third ends of the plurality of second textures are sequentially spaced at the bottom of the substrate, and the plurality of second textures are radiating from the third end to the fourth end; any two adjacent first textures and any two adjacent second textures enclose a reflective surface.

[0015] In this embodiment, the first texture includes a first end and a second end, and the second texture includes a third end and a fourth end. The first ends of the plurality of first textures are located at the bottom of the substrate along the height direction of the cooking appliance, and the first ends of the plurality of first textures are spaced apart. The plurality of first textures are arranged diverging from the first end to the second end. The third ends of the plurality of second textures are located at the bottom of the substrate along the height direction of the cooking appliance, and the third ends of the plurality of second textures are spaced apart. The plurality of second textures are arranged diverging from the third end to the fourth end. This allows the plurality of first textures and the plurality of second textures to be arranged to intersect, thereby allowing two adjacent first textures and two adjacent second textures to intersect to form a reflective surface. That is, by setting the first texture group and the second texture group, multiple reflective surfaces are formed, increasing the number of reflective surfaces. As a result, microwaves can be reflected multiple times through the multiple reflective surfaces, making the food heated more evenly.

[0016] In some embodiments, optionally, the distance between any two adjacent first textures gradually increases from the first end to the second end; and the distance between any two adjacent second textures gradually increases from the third end to the fourth end, so that the surface area of ​​the reflective surface gradually increases.

[0017] In this embodiment, the distance between two adjacent first textures gradually increases from the first end to the second end, and the distance between two adjacent second textures gradually increases from the third end to the fourth end. This makes the surface area of ​​the reflective surface enclosed by the two adjacent first textures and the two adjacent second textures gradually increase from the bottom to the periphery of the substrate. This makes the microwaves near the bottom center more concentrated after reflection by the reflective surface, thereby improving the heating efficiency and heating uniformity of the food.

[0018] In some embodiments, the plate body may optionally include a recessed portion, which is recessed toward a side away from the cooking cavity, and a first texture group and a second texture group are both disposed in the recessed portion; wherein, the recessed portion includes a fifth end and a sixth end disposed opposite to each other along the height direction of the cooking appliance, the fifth end is disposed near the bottom wall of the cooking cavity, the first end of the first texture and the third end of the second texture are both disposed at the fifth end of the recessed portion, and the first end of the first texture and the third end of the second texture are disposed near the middle of the fifth end.

[0019] In this embodiment, the plate includes a recessed portion that is recessed towards the side opposite to the cooking cavity to increase the volume of the cooking cavity. A reflective surface is disposed on the recessed portion, which improves the temperature uniformity within the cooking cavity while maintaining its volume. Simultaneously, a first texture group and a second texture group are disposed on the recessed portion, with the first end of the first texture and the third end of the second texture concentrated at the center of the fifth end of the recessed portion. This causes the multiple reflective surfaces to be arranged in a divergent pattern, resulting in different reflection effects at different locations and improving microwave uniformity within the cooking cavity.

[0020] In some embodiments, optionally, the first ends of a plurality of first textures and the third ends of a plurality of second textures are arranged alternately; and / or the first texture is a protrusion protruding into the cooking cavity or a groove recessed to the side away from the cooking cavity; and / or the second texture is a protrusion protruding into the cooking cavity or a groove recessed to the side away from the cooking cavity.

[0021] In this embodiment, the first ends of multiple first patterns and the third ends of multiple second patterns are sequentially staggered, making the first ends of the multiple first patterns and the third ends of the multiple second patterns more concentrated in the middle position of the bottom of the substrate. This makes the reflective surface formed by the first patterns and the second patterns more symmetrical, resulting in more uniform microwave reflection. Simultaneously, the sequential staggered arrangement of the first ends of the multiple first patterns and the third ends of the multiple second patterns increases the number of intersection points between the first patterns and the second patterns, thereby increasing the number of reflective surfaces formed by the first patterns and the second patterns. Optionally, the first pattern can be a groove or protrusion formed on the plate to separate adjacent reflective surfaces. Similarly, the second pattern can be a groove or protrusion formed on the plate to separate adjacent reflective surfaces.

[0022] In some embodiments, optionally, the first texture group and the second texture group are symmetrically arranged along the height direction of the cooking appliance; and / or the shape of the reflective surface includes any one or a combination thereof: rectangular or rhomboid.

[0023] In this embodiment, the first and second texture groups of the cooking appliance are symmetrically arranged in the height direction, making the reflective surface on the substrate more symmetrical, thereby making the microwaves in the cooking cavity more uniform after being reflected by the reflective surface. Optionally, the reflective surface can be rectangular or rhomboid to facilitate processing and manufacturing.

[0024] In some embodiments, the plate may optionally include heat dissipation holes located on one side of the cooking cavity; and / or the plate may also include air inlets located on one side of the cooking cavity.

[0025] In this embodiment, the plate is also provided with heat dissipation holes and / or air inlets, which can achieve heat dissipation of the electrical compartment.

[0026] Optionally, the cooking appliance includes a fan, with the fan's air inlet connected to an air intake hole and the fan's air outlet connected to a heat dissipation hole.

[0027] According to a second aspect of the present invention, a cooking appliance is also provided, comprising: a cooking cavity; a microwave generating unit for feeding microwaves into the cooking cavity; and a plate as described in any of the above embodiments, wherein one side of the plate having a first texture group and a second texture group is the inner wall surface of the cooking cavity.

[0028] The cooking appliance provided in the second aspect of this utility model, since it includes the plate body proposed in any of the above embodiments, has all the beneficial effects of the plate body.

[0029] In some embodiments, the cooking cavity may have an opening, and the plate is disposed opposite to the opening.

[0030] In this embodiment, the plate body is arranged opposite to the opening, that is, the plate body is the back plate of the cooking cavity. Multiple reflective surfaces are provided on the back plate, which can reflect microwaves towards the center of the cooking cavity, thereby improving the heating uniformity and heating efficiency of the food located in the center of the cooking cavity.

[0031] In some embodiments, the bottom of the cooking cavity is optionally provided with a microwave feed port, through which the microwave generator feeds microwaves into the cooking cavity.

[0032] In this embodiment, a microwave feed port is provided at the bottom of the cooking cavity, so that microwaves are fed into the cooking cavity from the bottom of the cooking cavity, so as to better reflect the microwaves.

[0033] Optionally, the microwave feed port at the bottom of the cooking cavity is located at the middle position of the bottom of the cooking cavity.

[0049] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0051] The following reference Figures 1 to 11 This invention describes a plate and cooking utensil proposed according to some embodiments of the present invention.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, according to one embodiment of the present invention, the present invention proposes a plate 1 for use in a cooking appliance, the cooking appliance including a microwave generator and a cooking cavity, the microwave generator being used to feed microwaves into the cooking cavity, a portion of the surface of the plate 1 being the inner wall surface of the cooking cavity, the plate 1 including: a substrate 10, the substrate 10 having a first texture group 12 and a second texture group 14, the first texture group 12 and the second texture group 14 being located on the side of the substrate 10 facing the cooking cavity, the first texture group 12 including a plurality of first textures 120, the second texture group 14 including a plurality of second textures 140, wherein the plurality of first textures 120 and the plurality of second textures 140 are intersected to enclose a plurality of reflective surfaces 16, the reflective surfaces 16 being used to reflect microwaves emitted by the microwave generator.

[0053] The plate 1 provided by this utility model is used in a cooking appliance, which includes a microwave generator and a cooking cavity. A portion of the surface of the plate 1 forms the inner wall of the cooking cavity. The plate 1 includes a substrate 10. A first texture group 12 and a second texture group 14 are provided on the side of the substrate 10 facing the cooking cavity. The first texture group 12 includes multiple first textures 120, and the second texture group 14 includes multiple second textures 140. The multiple first textures 120 and multiple second textures 140 are interleaved, thereby forming multiple reflective surfaces 16 on the side of the substrate 10 that forms the inner wall of the cooking cavity. Thus, after the microwave generator feeds microwaves into the cooking cavity, the reflective surfaces 16 can reflect the microwaves multiple times, increasing the number of microwave reflections and making the microwave distribution within the cooking cavity more uniform. This improves the temperature uniformity when microwaves heat food, thereby improving the cooking effect and shortening the cooking time.

[0054] It is understandable that the surface of the plate 1 with the first texture group 12 and the second texture group 14 forms the inner wall surface of the cooking cavity.

[0055] Optionally, the cooking appliance may include a plate 1, and the plate 1 and a plurality of other plate-like structures enclose a cooking cavity, or the cooking appliance may include a plurality of plates 1, and the plurality of plates 1 enclose a cooking cavity, wherein the surface of each plate 1 forming the inner wall of the cooking cavity is provided with a first texture group 12 and a second texture group 14.

[0056] Optionally, the reflective surface 16 is a non-planar structure, so that microwaves incident on the reflective surface 16 can be reflected to a position different from the incident direction, thereby increasing the uniformity of the microwave energy field in the cooking cavity.

[0057] In some embodiments, the reflective surface 16 may be convex toward the interior of the cooking cavity or recessed toward the side opposite to the cooking cavity.

[0058] In this embodiment, the reflective surface 16 is convex toward the interior of the cooking cavity or recessed toward the side away from the cooking cavity, thereby reflecting microwaves in different directions, improving the microwave uniformity in the cooking cavity, and thus improving the uniformity of heating of the food.

[0059] Optionally, all reflective surfaces 16 protrude into the interior of the cooking cavity, or all reflective surfaces 16 are recessed to the side away from the cooking cavity, or a portion of the reflective surfaces 16 protrude into the interior of the cooking cavity and another portion of the reflective surfaces 16 are recessed to the side away from the cooking cavity.

[0060] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, optionally, the cross-section of the reflective surface 16 is arc-shaped; and / or both the first texture 120 and the second texture 140 are arc-shaped.

[0061] In this embodiment, the cross-section of the reflective surface 16 is arc-shaped. On the one hand, this increases the area of ​​the reflective surface 16 and improves the microwave reflection effect. On the other hand, the arc-shaped reflective surface 16 can change the angle of the reflected microwaves, making the microwaves in the cooking cavity more uniform, thereby improving the cooking effect on the food and making the food heat more evenly.

[0062] Optionally, the cross-section of the reflective surface 16 is a cross-section of the reflective surface 16 along a direction perpendicular to the substrate 10. Optionally, both the first texture 120 and the second texture 140 are arc-shaped. On the one hand, this increases the length of the first texture 120 and the second texture 140, thereby increasing the number of intersection points of the first texture 120 and the second texture 140, and thus increasing the number of reflective surfaces 16. On the other hand, this arrangement also makes the edges of the reflective surface 16 arc-shaped, which can increase the overall surface area of ​​the reflective surface 16, thereby helping to increase the number of microwave reflections.

[0063] In some embodiments, the first texture 120 and the second texture 140 are optionally bent in opposite directions.

[0064] In this embodiment, the first texture 120 and the second texture 140 are bent in opposite directions, which increases the length of the first texture 120 and the second texture 140, thereby increasing the number of reflective surfaces 16 and improving the number of microwave reflections. At the same time, it also makes the design of the plate 1 more aesthetically pleasing.

[0065] It is understandable that the first texture 120 and the second texture 140 are bent in opposite directions. On the one hand, this arrangement increases the length of the first texture 120 and the second texture 140, thereby increasing the number of points where the first texture 120 and the second texture 140 can intersect and increasing the number of reflective surfaces 16. On the other hand, this arrangement also makes the first texture group 12 and the second texture group 14 intersect in a shape similar to two sets of water ripples, making the overall shape more beautiful.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the first texture 120 includes a first end 122 and a second end 124. The first ends 122 of the plurality of first textures 120 are located at the bottom of the substrate 10 along the height direction of the cooking appliance, and the first ends 122 of the plurality of first textures 120 are sequentially spaced at the bottom of the substrate 10. The plurality of first textures 120 are radiating from the first end 122 to the second end 124. The second texture 140 includes a third end 142 and a fourth end 144. The third ends 142 of the plurality of second textures 140 are located at the bottom of the substrate 10 along the height direction of the cooking appliance, and the third ends 142 of the plurality of second textures 140 are sequentially spaced at the bottom of the substrate 10. The plurality of second textures 140 are radiating from the third end 142 to the fourth end 144. A reflective surface 16 is formed between any two adjacent first textures 120 and any two adjacent second textures 140.

[0067] In this embodiment, the first texture 120 includes a first end 122 and a second end 124, and the second texture 140 includes a third end 142 and a fourth end 144. The first ends 122 of the plurality of first textures 120 are located at the bottom of the substrate 10 along the height direction of the cooking appliance, and the first ends 122 of the plurality of first textures 120 are spaced apart, and the plurality of first textures 120 are diverging from the first end 122 to the second end 124; the third ends 142 of the plurality of second textures 140 are located at the bottom of the substrate 10 along the height direction of the cooking appliance, and the third ends 142 of the plurality of second textures 140 are spaced apart. The third end 142 is spaced apart, and multiple second textures 140 are arranged diverging from the third end 142 to the fourth end 144, so that multiple first textures 120 and multiple second textures 140 can be arranged to cross each other. This allows two adjacent first textures 120 and two adjacent second textures 140 to cross and form a reflective surface 16. That is, through the arrangement of the first texture group 12 and the second texture group 14, multiple reflective surfaces 16 are formed, increasing the number of reflective surfaces 16. As a result, microwaves can be reflected multiple times through multiple reflective surfaces 16, making the food heated more evenly.

[0068] Optionally, the first ends 122 of a plurality of first textures 120 are arranged at intervals in the horizontal direction of the plate body 1. The third ends 142 of a plurality of second textures 140 are arranged at intervals in the horizontal direction of the plate body 1.

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the distance between any two adjacent first textures 120 gradually increases from the first end 122 to the second end 124; and the distance between any two adjacent second textures 140 gradually increases from the third end 142 to the fourth end 144, so that the surface area of ​​the reflective surface 16 gradually increases.

[0070] In this embodiment, the distance between two adjacent first textures 120 gradually increases from the first end 122 to the second end 124, and the distance between two adjacent second textures 140 gradually increases from the third end 142 to the fourth end 144. This makes the surface area of ​​the reflective surface 16 enclosed by the two adjacent first textures 120 and the two adjacent second textures 140 gradually increase from the bottom to the periphery of the substrate 10. This makes the microwaves near the bottom center more concentrated after reflection by the reflective surface 16, thereby improving the heating efficiency and heating uniformity of the food.

[0071] Understandably, ingredients are typically placed in a tray inside the cooking cavity, bringing them closer to the center of the bottom.

[0072] In some embodiments, the plate 1 may optionally include a recessed portion 17, which is recessed toward the side opposite to the cooking cavity. The first texture group 12 and the second texture group 14 are both disposed in the recessed portion 17. The recessed portion 17 includes a fifth end 170 and a sixth end 172 disposed opposite to each other along the height direction of the cooking appliance. The fifth end 170 is disposed near the bottom wall of the cooking cavity. The first end 122 of the first texture 120 and the third end 142 of the second texture 140 are both disposed in the fifth end 170 of the recessed portion 17, and the first end 122 of the first texture and the third end 142 of the second texture are disposed near the middle of the fifth end 170.

[0073] In this embodiment, the plate 1 includes a recessed portion 17, which is recessed towards the side opposite to the cooking cavity to increase the volume of the cooking cavity. A reflective surface 16 is disposed on the recessed portion 17, which can improve the temperature uniformity within the cooking cavity while ensuring the volume of the cooking cavity. Simultaneously, a first texture group 12 and a second texture group 14 are disposed on the recessed portion 17, and the first end 122 of the first texture 120 and the third end 142 of the second texture 140 are concentrated in the middle of the fifth end 170 of the recessed portion 17, causing the multiple reflective surfaces 16 to be arranged in a divergent pattern. This allows the reflective effects of the reflective surfaces 16 at different positions to vary, thereby improving the microwave uniformity within the cooking cavity.

[0074] like Figure 5 As shown, in some embodiments, optionally, the first ends 122 of a plurality of first textures 120 and the third ends 142 of a plurality of second textures 140 are arranged alternately; and / or the first textures 120 are protrusions protruding into the cooking cavity or grooves recessed to the side away from the cooking cavity; and / or the second textures 140 are protrusions protruding into the cooking cavity or grooves recessed to the side away from the cooking cavity.

[0075] In this embodiment, the first ends 122 of the plurality of first patterns 120 and the third ends 142 of the plurality of second patterns 140 are arranged alternately, making the first ends 122 of the plurality of first patterns 120 and the third ends 142 of the plurality of second patterns 140 more concentrated in the middle position of the bottom of the substrate 10. This makes the reflective surface 16 formed by the first patterns 120 and the second patterns 140 more symmetrical, so that the microwaves reflected by the reflective surface 16 are more uniform. At the same time, the alternate arrangement of the first ends 122 of the plurality of first patterns 120 and the third ends 142 of the plurality of second patterns 140 can also increase the number of intersection points of the first patterns 120 and the second patterns 140, thereby increasing the number of reflective surfaces 16 formed by the first patterns 120 and the second patterns 140. Optionally, the first texture 120 may be a groove or protrusion formed on the plate 1 to separate adjacent reflective surfaces 16. Similarly, the second texture 140 may be a groove or protrusion formed on the plate 1 so that the second texture 140 can separate adjacent reflective surfaces 16.

[0076] Optionally, the first ends 122 of the plurality of first textures 120 and the third ends 142 of the plurality of second textures 140 are arranged alternately in the horizontal direction of the plate body 1.

[0077] Optionally, when the reflective surface 16 protrudes into the cooking cavity, the first texture 120 and the second texture 140 are both grooves recessed to the side away from the cooking cavity; when the reflective surface 16 is recessed to the side away from the cooking cavity, the first texture 120 and the second texture 140 are both protrusions protruding into the cooking cavity.

[0078] like Figure 5 As shown, in some embodiments, optionally, the first texture group 12 and the second texture group 14 are symmetrically arranged along the height direction of the cooking appliance; and / or the shape of the reflective surface 16 includes any one or a combination thereof: rectangular or rhomboid.

[0079] In this embodiment, the first texture group 12 and the second texture group 14 are symmetrically arranged along the height direction of the cooking appliance, making the reflective surface 16 on the substrate 10 more symmetrical, thereby making the microwaves in the cooking cavity more uniform after being reflected by the reflective surface 16. Optionally, the reflective surface 16 can be rectangular or rhomboid to facilitate processing and manufacturing.

[0080] like Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, the plate 1 may optionally include a heat dissipation hole 18, which is located on one side of the cooking cavity; and / or the plate 1 may also include an air inlet hole 19, which is located on one side of the cooking cavity.

[0081] In this embodiment, the plate 1 is also provided with heat dissipation holes 18 and / or air inlets 19, which can achieve heat dissipation of the electrical compartment.

[0082] Optionally, the heat dissipation hole 18 and / or the air inlet hole 19 are provided on one side of the cooking cavity along the width direction of the cooking appliance.

[0083] According to one embodiment of the present invention, a cooking appliance is also proposed, comprising: a cooking cavity; a microwave generator for feeding microwaves into the cooking cavity; and a plate 1 as described in any of the above embodiments, wherein one side of the plate 1 having a first texture group 12 and a second texture group 14 is the inner wall surface of the cooking cavity.

[0084] The cooking appliance provided by this utility model, because it includes the plate 1 proposed in any of the above embodiments, has all the beneficial effects of the plate 1.

[0085] In some embodiments, the cooking cavity is optionally provided with an opening, and the plate 1 is disposed opposite to the opening.

[0086] In this embodiment, the plate 1 is arranged opposite to the opening, that is, the plate 1 is the back plate of the cooking cavity. Multiple reflective surfaces 16 are provided on the back plate, which can reflect microwaves to the center of the cooking cavity, thereby improving the heating uniformity and heating efficiency of the food located in the center of the cooking cavity.

[0087] In some embodiments, the bottom of the cooking cavity is optionally provided with a microwave feed port, through which the microwave generator feeds microwaves into the cooking cavity.

[0088] In this embodiment, a microwave feed port is provided at the bottom of the cooking cavity, so that microwaves are fed into the cooking cavity from the bottom of the cooking cavity, so as to better reflect the microwaves.

[0089] Optionally, the cooking cavity also includes two side walls, which are connected to the top and bottom walls of the cooking cavity along its height, respectively. The two side walls enclose an opening at their front ends. Optionally, one side wall of the cooking cavity has another microwave feed port. The bottom of the cooking cavity has a first microwave feed port, and the side wall has a second microwave feed port. The first and second microwave feed ports are located on two mutually perpendicular walls of the cooking cavity. When the microwave generator feeds microwaves into the cooking cavity through the first and second microwave feed ports, two orthogonal microwave beams enter the cooking cavity. These beams interfere with each other, increasing the uniformity of microwaves within the cooking cavity. This arrangement also makes the arrangement of the first texture group 12 and the second texture group 14 more compatible with the microwave feeding method, which is beneficial for improving the cooking effect.

[0090] According to some embodiments of this application, the cooking appliance proposed in this application includes a microwave oven. Optionally, the microwave oven is a tabletop microwave oven. The microwave oven includes an inner rear panel with two orthogonal wave patterns (e.g., a first pattern group 12 and a second pattern group 14). The patterns form rhomboid blocks (e.g., a reflective surface 16) between them, making the overall shape resemble two intersecting water ripples. This design is aesthetically pleasing and also conforms to the orthogonal wave technology used in the product. Optionally, the arc-shaped rhomboid blocks on the back are arranged along the wave pattern direction, making the reflected microwaves more uniform and the heating uniformity better.

[0091] Optionally, the inner rear panel of the cooking cavity (e.g., panel 1) is mainly divided into four areas: the central shape feature area (i.e., the internal area of ​​the cavity), the upper right side is the heat dissipation system installation area (e.g., the area with heat dissipation holes 18), the lower right side is the air intake area (e.g., the area with air inlets), and the surrounding area is the fixing area for fixing the inner rear panel to other structures.

[0092] The central feature area has two bundles of rhomboid blocks (e.g., reflective surface 16) that gradually spread out in a water ripple shape. The rhomboid blocks spread upward from the bottom of the inner rear plate and gradually stop at the perimeter.

[0093] Optionally, each of the individual reflective surfaces 16 bulges outward.

[0094] In this utility model, the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium.
