Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cooking equipment, and particularly relates to a cooking device. BACKGROUND

[0002] At present, a cooking device with a baking function, such as an oven, commonly uses a heating method of arranging a heating element in a cooking cavity to heat food in the cooking cavity by releasing heat from the heating element. Part of the heat released by the heating element directly acts on the food, and the other part of the heat needs to be reflected by the inner wall of the cooking cavity to act on the food. However, after the heat is reflected by the inner wall of the cooking cavity, part of the reflected heat is blocked by the heating element, so it cannot act on the food, thereby reducing the cooking efficiency of the cooking device. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present application is to at least solve the problem that the heat reflected by the inner wall of the cooking cavity is blocked by the heating element and cannot act on the food. The purpose is achieved in the following way:

[0004] The first aspect of the present application provides a cooking device, which comprises:

[0005] a cooking cavity assembly comprising a plurality of support plates, the plurality of support plates being combined to form a cooking cavity;

[0006] a heating element, at least part of the heating element being arranged in the cooking cavity;

[0007] Part of the number of the support plates is located on the side of the middle part of the heating element away from the cooking cavity and is provided with a reflection part. At least part of the structure of the reflection part is arranged at an angle with the plate surface of the support plate where the reflection part is located. In the direction perpendicular to the support plate, the projection of the heating element on the support plate at least partially overlaps the projection of the reflection part on the support plate.

[0008] According to the cooking device of the present application, by at least partially overlapping the projection of the heating element on the support plate with the projection of the reflection part on the support plate in the direction perpendicular to the support plate, when the heating element generates heat, the heat emitted by the heating element towards the adjacent support plate acts on the reflection part. Since at least part of the structure of the reflection part is arranged at an angle with the plate surface of the support plate where the reflection part is located, part of the heat acting on the reflection part cannot return to the heating element in the original direction perpendicular to the plate surface of the support plate, but is reflected into the cooking cavity at an angle with the original flow direction of the heat. Thus, the blocking of the heating element to the reflected heat is reduced, and the reflected heat is more applied to the food in the cooking cavity, thereby improving the cooking efficiency of the cooking device.

[0009] In addition, the cooking device according to the present application can also have the following additional technical features:

[0010] In some embodiments of the present application, the support plate is provided with the reflection portion protruding towards the surface of the heating element; or, part of the support plate is recessed to form the reflection portion in a direction away from the heating element.

[0011] In some embodiments of the present application, the reflection portion comprises a first reflection portion and a second reflection portion connected with each other, and the first reflection portion and the second reflection portion are respectively formed by recessing part of the support plate in a direction away from the heating element.

[0012] In some embodiments of the present application, at least one of the first reflection portion and the second reflection portion is a planar plate structure.

[0013] In some embodiments of the present application, at least one of the first reflection portion and the second reflection portion is an arc-shaped plate structure.

[0014] In some embodiments of the present application, at least one of the first reflection portion and the second reflection portion comprises a plurality of reflection segments, and at least one reflection segment of the plurality of reflection segments is arranged at an angle with the plate surface of the support plate.

[0016] In some embodiments of the present application, the first reflection segment and the second reflection segment are symmetrical structures.

[0017] In some embodiments of the present application, the heating element comprises a tube body and a heating element; wherein at least part of the tube body is a transparent element, and / or the heating element is a graphene heating element.

[0018] In some embodiments of the present application, along the axial direction of the tube body, the size of the reflection portion is greater than or equal to the size of the part of the heating element arranged in the cooking cavity.

[0044] At present, the cooking device with baking function, such as oven, commonly used heating method is to set heating element in the cooking cavity, and heat the food in the cooking cavity through the heating element. Among them, a part of the heat released by the heating element directly acts on the food, and another part of the heat needs to be reflected by the inner wall of the cooking cavity and then acts on the food. However, after the heat is reflected by the inner wall of the cooking cavity, part of the reflected heat is blocked by the heating element, so it cannot act on the food, thereby reducing the cooking efficiency of the cooking device.

[0045] To at least solve the problem that the heat reflected by the inner wall of the cooking cavity is blocked by the heating element and cannot act on the food, the present application proposes a cooking device. According to the cooking device of the present application, the blocking of the reflected heat by the heating element can be reduced, and thus the reflected heat can act more on the food in the cooking cavity, thereby improving the cooking efficiency of the cooking device.

[0046] For the convenience of description, the cooking device in the embodiments of the present application is exemplified as an oven. Of course, the cooking device in the present application can also be other cooking equipment with baking function, such as oven microwave all-in-one machine, etc.

[0047] In combination with Figures 1 to 6As shown, in some embodiments of the present application, the cooking device 1 comprises a cooking cavity assembly 20 and a heating element 31, the cooking cavity assembly 20 comprises a plurality of support plates, the plurality of support plates enclose a cooking cavity 21, and at least part of the heating element 31 is arranged in the cooking cavity 21, wherein a part of the plurality of support plates is located on a side of the middle part of the heating element 31 away from the cooking cavity 21 and is provided with a reflecting part 221, at least part of the structure of the reflecting part 221 is arranged at an angle with the plate surface of the support plate on which the reflecting part 221 is located, and the projection of the heating element 31 on the support plate at least partially overlaps the projection of the reflecting part 221 on the support plate in a direction perpendicular to the plate surface of the support plate.

[0048] In some embodiments of the present application, the shell 10 is used to form the overall appearance structure of the cooking device 1, and the inside of the shell 10 is provided with a containing cavity for containing the cooking cavity assembly 20 and other components, which can include a circuit board, a cooling fan or other components. Wherein, when a user faces the cooking device 1, the side of the cooking device 1 facing the user is the front side, the side away from the user is the back side, the side on the left hand side of the user is the left side, and the side on the right hand side of the user is the right side.

[0049] The cooking cavity assembly 20 is arranged in the containing cavity, and the cooking cavity assembly 20 comprises a plurality of support plates, the plurality of support plates enclose a cooking cavity 21, and the cooking cavity 21 can be used for cooking food. Optionally, the plurality of support plates comprises a top support plate 22 and a bottom support plate 23 arranged oppositely, and a left support plate 24 and a right support plate 25 arranged oppositely, and the top support plate 22, the left support plate 24, the bottom support plate 23 and the right support plate 25 are sequentially connected in a head-to-tail manner and form a cavity structure with openings at the front and back ends. The plurality of support plates further comprises a rear support plate 26, the rear support plate 26 is arranged at the back of the cavity structure and is used to seal the opening at the back end of the cavity structure, so as to enclose the cooking cavity 21 with an opening at the front end by the top support plate 22, the left support plate 24, the bottom support plate 23, the right support plate 25 and the rear support plate 26.

[0050] Optionally, the cooking device 1 further comprises a door assembly 40, the door assembly 40 is arranged at the front end of the cooking cavity 21 and is used to close or open the front end opening of the cooking cavity 21. The cooking device 1 further comprises a control box assembly 50, the control box assembly 50 is used to be electrically connected with electrical appliances of the cooking device 1, such as a circuit board, a fan and the like, and is used to control the working state of the electrical appliances. Optionally, the control box assembly 50 can be arranged below the door assembly 40.

[0051] Part of the structure of the heating element 31 can be arranged in the cooking cavity 21. The heating element 31 can release heat in the working state and be used to heat the food in the cooking cavity 21. The heat emitted by the side surface of the heating element 31 facing the food can directly act on the food in the cooking cavity 21. The heat emitted by the other side surface of the heating element 31 away from the food, i.e. the other side surface of the heating element 31 facing the other side surface of the support plate, needs to act on the support plate first and then act on the food after being reflected by the support plate. When the surface of the support plate is perpendicular to the projection direction of the heat emitted by the heating element 31, the heat reflected by the support plate returns along the original path and is blocked by the heating element 31. Therefore, in order to change the projection direction of the heat reflected by the support plate, the part of the support plate located on the side of the middle part of the heating element 31 away from the cooking cavity 21 is provided with a reflecting part 221. At least part of the structure of the reflecting part 221 is arranged at an angle with the surface of the support plate on which the reflecting part 221 is located, and the projection of the heating element 31 on the support plate and the projection of the reflecting part 221 on the support plate at least partially overlap in the direction perpendicular to the surface of the support plate.

[0052] Optionally, the cooking cavity 21 can be provided with heating elements 31 on both sides in the vertical direction. The food can be placed between the upper and lower heating elements 31 when cooking in the cooking cavity 21, so that the upper and lower surfaces of the food can be heated by the upper and lower heating elements 31, respectively. The middle part of the heating element 31 away from the cooking cavity 21 is located on the side of the top support plate 22, and the middle part of the heating element 31 away from the cooking cavity 21 is located on the side of the bottom support plate. The top support plate 22 is provided with a reflecting part 221 opposite to the upper heating element 31, and / or the bottom support plate 23 is provided with a reflecting part 221 opposite to the lower heating element 31. For the convenience of description, the embodiment of the present application only takes the top support plate 22 provided with a reflecting part 221 as an example for description.

[0053] The heat emitted by the upper heating element 31 towards the top support plate 22 acts on the top support plate 22. Part of the heat flows to the top support plate 22 in a direction that is not perpendicular to the surface of the top support plate 22, and is reflected by the reflection of the top support plate 22 to the inside of the cooking cavity 21 in a direction that is at an angle to the original flow direction, thereby reducing the shielding of the reflected heat by the heating element 31. Another part of the heat flows to the top support plate 22 in a direction that is perpendicular to the surface of the top support plate 22. Since the projection of the heating element 31 on the top support plate 22 and the projection of the reflection 221 on the top support plate 22 at least partially coincide in the direction that is perpendicular to the surface of the top support plate 22, the other part of the heat flowing to the top support plate 22 in the direction that is perpendicular to the surface of the top support plate 22 acts on the reflection 221 and flows to the inside of the cooking cavity 21 in a direction that is at an angle to the original flow direction under the action of the reflection 221, thereby reducing the shielding of the reflected heat by the heating element 31, and further making the reflected heat act more on the food in the cooking cavity 21, improving the cooking efficiency of the cooking device 1. At the same time, the reflected heat can act on the food in the cooking cavity 21 at different angles, thereby heating different surfaces of the food, and further improving the cooking efficiency and effect of the food.

[0054] It should be noted that the angle in the present application refers to the angle between the two, and the range value is 0-180°. Among them, 0° and 180° are not included.

[0055] In combination Figures 2 to 6 As shown in the drawings, in some embodiments of the present application, the surface of the top support plate 22 facing the heating element 31 is convexly provided with a reflection 221, i.e. the reflection 221 can be provided on the side of the top support plate 22 facing the heating element 31. Alternatively, part of the support plate is recessed to form a reflection 221 facing away from the heating element 31, i.e. the reflection 221 can be provided on the side of the top support plate 22 facing away from the heating element 31.

[0056] When the reflection 221 is provided on the side of the top support plate 22 facing the heating element 31, the reflection 221 can be an integral structure with the top support plate 22, and is formed by stamping or bending part of the top support plate 22 towards the heating element 31; or the reflection 221 can be a separate structure from the top support plate 22, and is connected to the surface of the top support plate 22 facing the heating element 31 by bonding, welding or clamping. When the reflection 221 is provided on the side of the top support plate 22 facing away from the heating element 31, the reflection 221 and the top support plate 22 can be an integral structure, and are formed by stamping or bending part of the top support plate 22 towards the heating element 31, so that the heat emitted by the heating element 31 towards the top support plate 22 can act on the reflection 221, and the flow direction angle of the reflected heat is adjusted by the reflection of the reflection 221.

[0057] Combining Figures 2 to 6 As shown in some embodiments of the present application, the reflecting part 221 comprises a first reflecting part 2211 and a second reflecting part 2212 connected with each other, and the first reflecting part 2211 and the second reflecting part 2212 are respectively formed by recessing part of the top supporting plate 22 towards the direction away from the heating element 31.

[0058] In some embodiments of the present application, the reflecting part 221 comprises a first reflecting part 2211 and a second reflecting part 2212 connected with each other, and by setting the two-part structure, it is convenient to form the structure with an angle to the plate surface of the top supporting plate 22 by stamping or bending. In order to reduce the space occupied by the reflecting part 221 in the cooking cavity 21 and improve the space utilization of the cooking cavity 21, the first reflecting part 2211 and the second reflecting part 2212 are respectively arranged on the side of the top supporting plate 22 away from the heating element 31 and are formed by recessing part of the top supporting plate 22 towards the direction away from the heating element 31.

[0059] Combining Figures 2 to 6 As shown in some embodiments of the present application, at least one of the first reflecting part 2211 and the second reflecting part 2212 is a planar plate structure.

[0060] Optionally, the first reflecting part 2211 and the second reflecting part 2212 can be respectively planar plate structures, and the planar plate structure is convenient to manufacture, and the whole plate structure of the top supporting plate 22 can be stamped to form the first reflecting part 2211 and the second reflecting part 2212.

[0061] As Figure 6 shown, Figure 6 The direction indicated by the straight arrow is the flow direction of part of the heat emitted by the heating element 31, wherein part of the heat emitted by the heating element 31 acts on the first reflecting part 2211 and the second reflecting part 2212 in the direction perpendicular to the plate surface of the top supporting plate 22. Since the first reflecting part 2211 and the second reflecting part 2212 are respectively arranged at an angle to the plate surface of the top supporting plate 22, the reflected heat is respectively arranged at an angle to the original flow direction of the heat, thereby reducing the shielding of the heat by the heating element 31, allowing more heat to act on the food in the cooking cavity 21, and improving the cooking efficiency of the cooking device 1. Optionally, the first reflecting part 2211 and the second reflecting part 2212 are symmetrical structures.

[0062] Combining Figure 6 and Figure 7 As shown in some embodiments of the present application, the heating element 31 comprises a pipe body 311 and a heating element 312; wherein at least part of the pipe body 311 is a transparent piece, and / or the heating element 312 is a graphene heating element.

[0063] In some embodiments of the present application, the heating element 31 comprises a tube body 311 and a heating element 312 arranged in the tube body 311, the tube body 311 is used to fix the heating element 312, and the heat generated by the heating element 312 can pass through the tube body 311 and flow into the cooking cavity 21. Optionally, the tube body 311 can be a transparent member, which is a glass tube, so as to facilitate the heat generated by the heating element 312 to pass through the tube body 311, and at the same time, to reduce the heat reflected by the inner wall of the cooking cavity 21 and blocked by the tube body 311. The heating element 312 can be a graphene heating element, which has good heating efficiency, but at the same time, the graphene heating element is easy to block the reflected heat, therefore, the reflection part 221 is arranged on the support plate on the side of the middle part of the heating element 31 away from the cooking cavity 21. For the convenience of description, the first reflection part 2211 is taken as an example to illustrate the reflection of heat. The heat reflected by the first reflection part 2211 does not need to completely avoid the heating element 31, because the heat can pass through the glass tube, therefore, the angle of the reflected heat only needs to avoid the heating element 312. Optionally, the heating element 31 further comprises a mounting head 313 arranged at both ends of the tube body 311 along the axial direction of the tube body 311, and used to fix the tube body 311. Optionally, the first mounting hole 241 is arranged through the left support plate 24 and the right support plate 25 arranged opposite to each other along the axial direction of the tube body 311, and the mounting head 313 at both ends of the heating element 31 can pass through the first mounting hole 241 on both sides respectively, so as to fix the tube body 311 and the heating element 312 in the cooking cavity 21.

[0064] In some other embodiments of the present application, one of the first reflection part 2211 and the second reflection part 2212 can be arranged in a planar plate structure, and the other one can be arranged in an arc structure or other regular or irregular structure.

[0065] In some embodiments of the present application, the heating element 312 can also be a metal heating wire, which is placed in the tube body 311, so as to release heat through the tube body 311. Alternatively, the heating element 31 can also be other heating structure arranged in the cooking cavity 21, and the reflection part 221 is arranged on the support plate on the side of the middle part of the heating element 31 away from the cooking cavity 21, which can also reduce the blocking of the reflected heat by the heating element 31.

[0066] In combination with Figures 2 to 6 As shown in some embodiments of the present application, along the axial direction of the tube body 311, the size of the reflection part 221 is greater than or equal to the size of the part of the heating element 31 arranged in the cooking cavity 21.

[0067] By arranging the size of the reflection part 221 along the axial direction of the tube body 311 to be greater than or equal to the size of the part of the heating element 31 arranged in the cooking cavity 21, the reflection range of the heat generated by the heating element 312 along the axial direction of the tube body 311 can be improved, so as to improve the heating efficiency of the heating element 31.

[0068] Combination Figure 3 , Figure 5 and Figure 8 As shown, in some embodiments of this application, at least one of the first reflective portion 2211 and the second reflective portion 2212 is an arc-shaped plate structure.

[0069] Optionally, the first reflective portion 2211 and the second reflective portion 2212 can each be an arc-shaped plate structure. Arc-shaped plate structures are easy to manufacture, and the top support plate 22 of the entire plate structure can be stamped to form the first reflective portion 2211 and the second reflective portion 2212. The corresponding arc radii of the first reflective portion 2211 and the second reflective portion 2212 can be equal or unequal. When the corresponding arc radii of the first reflective portion 2211 and the second reflective portion 2212 are equal, the first reflective portion 2211 and the second reflective portion 2212 can form a continuous arc-shaped structure. Optionally, the first reflective portion 2211 and the second reflective portion 2212 are symmetrical structures.

[0070] In some embodiments of this application, one of the first reflective portion 2211 and the second reflective portion 2212 may be configured as an arc-shaped structure, while the other may be configured as another regular or irregular shape.

[0071] Combination Figure 3 , Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of this application, at least one of the first reflective portion 2211 and the second reflective portion 2212 includes a plurality of reflective segments, and at least one of the plurality of reflective segments is arranged at an angle to the surface of the support plate.

The first reflective segment 22111 has an arc-shaped plate structure and is set at an angle to the surface of the top support plate 22, while the second reflective segment 22112 has a planar plate structure and is also set at an angle to the surface of the top support plate 22. The arc-shaped surface of the arc-shaped plate structure of the first reflective segment 22111 protrudes towards the direction close to the heating element 31. Optionally, the first reflective portion 2211 and the second reflective portion 2212 are symmetrical structures.

[0074] like Figure 10As shown, in some embodiments of this application, the first reflective portion 2211 includes a first reflective segment 22111 and a second reflective segment 22112, with the first reflective segment 22111 disposed on the side of the second reflective segment 22112 facing away from the second reflective portion 2212. The first reflective segment 22111 is an arc-shaped plate structure and is set at an angle to the surface of the top support plate 22, while the second reflective segment 22112 is a planar plate structure and is also set at an angle to the surface of the top support plate 22. The arc-shaped surface of the arc-shaped plate structure of the first reflective segment 22111 protrudes in a direction away from the heating element 31. Optionally, the first reflective portion 2211 and the second reflective portion 2212 are symmetrical structures.

[0075] like Figure 11 As shown, in some embodiments of this application, the first reflective portion 2211 includes a plurality of reflective segments connected in sequence, each of which is a planar plate-like structure. Some of these planar plate-like structures are parallel to the surface of the top support plate 22, while others are arranged at an angle to the surface of the top support plate 22.
