Description

Technical Field

[0001] The utility model relates to the technical field of microwave ovens, and more specifically to a microwave oven inner plate structure and a microwave oven. Background Art

[0002] Generally, the back plate of a microwave oven cavity is flat. When the microwave oven is working, the microwaves emitted by the microwave oven fall on the back plate in only one reflection direction. When the microwave pattern is limited, the microwaves are unevenly distributed in the cavity, and the cooked food is heated unevenly, resulting in poor uniformity of the cooked food, affecting the cooking effect, and greatly affecting customer experience and product satisfaction. Utility Model Content

[0003] The utility model provides a microwave oven inner plate structure and a microwave oven to overcome the problem that when the microwave mode is limited, microwaves are unevenly distributed in the cavity of the microwave oven in the prior art, thereby causing the cooked food to be heated unevenly.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a microwave oven inner plate structure, including an inner plate main body, on which a plurality of reflection units are formed inwardly concave or outwardly convex, and the reflection units have a plurality of reflection surfaces.

[0005] In the technical solution, the microwave oven inner plate structure can be installed on the rear side wall of the microwave oven cavity as needed, or the microwave oven inner plate structure can be installed on the left and right side walls of the microwave oven cavity. Compared with the flat rear plate installed in the microwave oven cavity in the prior art, since a plurality of reflecting units are formed on the inner plate body which is concave inward or convex outward, and the reflecting units have a plurality of reflecting surfaces, the reflecting area of ​​the microwave on the inner plate body can be increased, thereby increasing the reflecting surface of the microwave in the cavity, and further making the microwave more evenly distributed in the cavity, thereby improving the uniformity of heating of the cooked food.

[0006] Preferably, the reflecting surfaces are not in the same plane, and the reflecting surfaces are sequentially connected and intersect at the center point. The outer edges of the reflecting surfaces are coplanar and form a polygonal structure, and the distance between the center point and the plane where the polygonal structure is located is L. In the present technical solution, since the outer edges of the reflecting surfaces are coplanar and form a polygonal structure, the distance between the center point and the plane where the polygonal structure is located is L, so that the reflecting surfaces can be not in the same plane. The different planes of the reflecting surfaces make the reflecting surfaces not on the same plane, thereby increasing the reflection area of ​​the microwave on the inner plate body. It should be noted that the outer edge of each reflecting surface refers to the outer side length of each reflecting surface, and the outer side length refers to the side length that is not coplanar with the connected reflecting surfaces.

[0007] Preferably, there are three reflective surfaces, each of which is a quadrilateral structure, and the polygonal structure is a hexagonal structure. In the technical solution of the present application, the polygonal structure is a hexagonal structure. Such a structural design is conducive to the arrangement of adjacent reflective units. The hexagonal structures of two adjacent reflective units can share a side length, and more reflective units can be distributed on the inner plate body, thereby increasing the reflective area on the inner plate body.

[0008] Preferably, each of the reflective surfaces is a rhombus, and the polygonal structure is a regular hexagonal structure. In the technical solution of the present application, since the polygonal structure is a regular hexagonal structure and the reflective surface is a rhombus, the reflective unit and its six adjacent reflective units can share a side length while improving the uniformity of reflection, so that there is no interval between the reflective unit and its six adjacent reflective units, thereby increasing the number of reflective units distributed on the inner plate body and further improving the reflection area.

[0009] Preferably, each reflecting surface is a first reflecting surface, a second reflecting surface and a third reflecting surface, the first reflecting surface intersects with the second reflecting surface at a first side length, the first reflecting surface intersects with the third reflecting surface at a second side length, the second reflecting surface intersects with the third reflecting surface at a third side length, and the first side length, the second side length and the third side length intersect at the center point; the outer side lengths of the first reflecting surface, the second reflecting surface and the third reflecting surface are coplanar and form the regular hexagonal structure.

[0010] Preferably, the side length of the regular hexagonal structure is greater than 10 mm, and the distance L ranges from 1 mm to 6 mm. In the present technical solution, the distance L can be set as needed. Since the reflection unit is recessed in the direction away from the inner cavity, when the distance L is larger, the depth of each reflection surface recessed in the direction away from the inner cavity is larger.

[0011] Preferably, there are six reflecting surfaces, each of which is a triangular structure, and the polygonal structure is a hexagonal structure. In the present technical solution, the reflecting surface is a triangular structure and there are six reflecting surfaces, so that the reflecting area can be increased. In addition, the polygonal structure is a hexagonal structure. The use of such a structural design is conducive to the arrangement of adjacent reflecting units. The hexagonal structures of two adjacent reflecting units can share a side length, and more reflecting units can be distributed on the inner plate body, thereby increasing the reflecting area on the inner plate body.

[0012] Preferably, the triangular structure is an isosceles triangular structure, and the polygonal structure is a regular hexagonal structure. In the present technical solution, since the polygonal structure is a regular hexagonal structure and the reflective surface is an isosceles triangular structure, the reflective unit and its six adjacent reflective units can share a side length while improving the uniformity of reflection, so that there is no interval between the reflective unit and its six adjacent reflective units, thereby increasing the number of reflective units distributed on the inner plate body and further improving the reflection area.

[0013] Preferably, each of the reflection units is connected in sequence and evenly distributed in an array on the inner plate body. In the present technical solution, each of the reflection units is connected in sequence along the length direction of the inner plate body, and each of the reflection units is connected in sequence along the height direction of the inner plate body, so that the reflection units can be connected in sequence and evenly distributed in an array direction on the inner plate body, thereby increasing the number of reflection units on the inner plate body, thereby increasing the reflection area of ​​the microwave.

[0014] Another aspect of the utility model provides a microwave oven, comprising a furnace body and a furnace door rotatably connected to the furnace body, and also comprising the microwave oven inner plate structure as described above, wherein the microwave oven inner plate structure is arranged on the inner wall of the furnace body.

[0015] Compared with the prior art, the beneficial effect of the utility model is as follows: in the utility model, since a number of reflection units are formed on the inner plate body by being concave inward or convex outward, and the reflection units have multiple reflection surfaces, the reflection area of ​​the microwaves on the inner plate body can be increased, thereby increasing the reflection surface of the microwaves in the cavity, and further making the microwaves more evenly distributed in the cavity, thereby improving the uniformity of heating of cooked food.

DETAILED DESCRIPTION

[0022] The drawings are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and should not be construed as limiting the present invention.

[0023] Example 1

[0024] like Figure 1 , Figure 2 As shown, a microwave oven inner plate structure comprises an inner plate body 1, on which a plurality of reflection units 2 are formed by being recessed inward or protruding outward, and a plurality of reflection surfaces 3 are provided on the reflection unit 2. In this embodiment, the microwave oven inner plate structure can be installed on the rear side wall of the microwave oven cavity as required, or the microwave oven inner plate structure can be installed on the left and right side walls of the microwave oven cavity. Compared with the planar rear plate installed in the microwave oven cavity in the prior art, since a plurality of reflection units 2 are formed by being recessed inward or protruding outward on the inner plate body 1, and a plurality of reflection surfaces 3 are provided on the reflection unit 2, the reflection area of ​​the microwave on the inner plate body 1 can be increased, thereby increasing the reflection surface 3 of the microwave in the cavity, and further making the microwave more evenly distributed in the cavity, thereby improving the uniformity of heating of the cooked food. It should be noted that the normal of each reflection surface 3 is preferably toward the center of the cavity, so as to further improve the cooking effect on the food. It should also be noted that when the inner plate body 1 protrudes toward the direction close to the cavity to form a plurality of reflection units 2, the formed reflection units 2 will occupy the space of the cavity. Therefore, it is best to form a plurality of reflective units 2 by recessing the inner plate body 1 in a direction away from the inner cavity. This will not affect the space of the inner cavity and will also facilitate cleaning of the inner plate structure of the microwave oven.

[0025] like Figure 2 As shown, the reflecting surfaces 3 are not in the same plane, and the reflecting surfaces 3 are sequentially connected and intersect at the center point 4. The outer edges of the reflecting surfaces 3 are coplanar and form a polygonal structure 5. The distance between the center point 4 and the plane where the polygonal structure 5 is located is L. In this embodiment, since the outer edges of the reflecting surfaces 3 are coplanar and form a polygonal structure 5 (such as Figure 4As shown in FIG. 1 , the distance between the center point 4 and the plane where the polygonal structure 5 is located is L, so that the reflection surfaces 3 can be skewed. The skewed reflection surfaces 3 make the reflection surfaces 3 not on the same plane, thereby increasing the reflection area of ​​the microwave on the inner plate body 1. It should be noted that the outer edge of each reflection surface 3 refers to the outer side length of each reflection surface 3, and the outer side length refers to the side length that is not shared with the connected reflection surface 3.

[0026] like Figure 2 As shown, there are three reflective surfaces 3, each of which is a quadrilateral structure, and the polygonal structure 5 is a hexagonal structure. In this embodiment, the polygonal structure 5 is a hexagonal structure. Such a structural design is conducive to the arrangement of adjacent reflective units 2. The hexagonal structures of two adjacent reflective units 2 can share a side length, and more reflective units 2 can be distributed on the inner plate body 1, thereby increasing the reflection area on the inner plate body 1.

[0027] like Figure 2 As shown, each reflective surface 3 is a rhombus, and the polygonal structure 5 is a regular hexagonal structure. In this embodiment, since the polygonal structure 5 is a regular hexagonal structure and the reflective surface 3 is a rhombus, the reflective unit 2 and the six adjacent reflective units 2 can share a side length while improving the uniformity of reflection, so that there is no interval between the reflective unit 2 and the six adjacent reflective units 2, thereby increasing the number of reflective units 2 distributed on the inner plate body 1 and further improving the reflection area.

[0028] like Figure 2 As shown, each reflective surface 3 is a first reflective surface 31, a second reflective surface 32 and a third reflective surface 33. The first reflective surface 31 and the second reflective surface 32 intersect at a first side length 34, the first reflective surface 31 and the third reflective surface 33 intersect at a second side length 35, the second reflective surface 32 and the third reflective surface 33 intersect at a third side length 36, and the first side length 34, the second side length 35 and the third side length 36 intersect at a center point 4; the outer sides of the first reflective surface 31, the second reflective surface 32 and the third reflective surface 33 are coplanar and form a regular hexagonal structure. Figure 2 As shown, the outer side length of the first reflecting surface 31 refers to the other two sides except the first side length 34 and the second side length 35; the outer side length of the second reflecting surface 32 refers to the other two sides except the first side length 34 and the third side length 36; the outer side length of the third reflecting surface 33 refers to the other two sides except the second side length 35 and the third side length 36, and the six outer side lengths are used to form a regular hexagonal structure (such as Figure 4 shown).

[0029] like Figure 2 , Figure 3As shown, the side length A of the regular hexagonal structure is greater than 10 mm, and the distance L ranges from 1 mm to 6 mm. In this embodiment, the distance L can be set as needed. Since the reflection unit 2 is recessed in the direction away from the inner cavity, when the distance L is larger, the depth of each reflection surface 3 recessed in the direction away from the inner cavity is larger.

[0030] like Figure 1 As shown, each reflection unit 2 is connected in sequence and evenly distributed in an array on the inner plate body 1. In this embodiment, each reflection unit 2 is connected in sequence along the length direction of the inner plate body 1 on the inner plate body 1, and each reflection unit 2 is connected in sequence along the height direction of the inner plate body 1 on the inner plate body 1, so that the reflection units 2 can be connected in sequence and evenly distributed in an array direction on the inner plate body 1, thereby increasing the number of reflection units 2 on the inner plate body 1, thereby increasing the reflection area of ​​the microwave.

[0031] Example 2

[0032] The difference from Example 1 is that there are six reflective surfaces 3, each of which is a triangular structure, and the polygonal structure 5 is a hexagonal structure. In this embodiment, the reflective surface 3 is a triangular structure and there are six reflective surfaces 3, so that the reflection area can be increased. In addition, the polygonal structure 5 is a hexagonal structure. The use of such a structural design is conducive to the arrangement of adjacent reflective units 2. The hexagonal structures of two adjacent reflective units 2 can share a side length, and then more reflective units 2 can be distributed on the inner plate body 1, thereby increasing the reflection area on the inner plate body 1.

[0033] Among them, the triangular structure is an isosceles triangular structure, and the polygonal structure 5 is a regular hexagonal structure. In this embodiment, since the polygonal structure 5 is a regular hexagonal structure and the reflecting surface 3 is an isosceles triangular structure, the reflecting unit 2 and the six adjacent reflecting units 2 can share a side length while improving the uniformity of reflection, so that there is no interval between the reflecting unit 2 and the six adjacent reflecting units 2, thereby increasing the number of reflecting units 2 distributed on the inner plate body 1 and further improving the reflection area.
