Description

Technical Field

[0001] This application claims the priority of a Chinese patent application with the application number “202310629868.7” and the application title “Door Assembly and Cooking Appliance” filed with the China National Intellectual Property Administration on May 30, 2023, and the entire content of this application is incorporated herein by reference.

[0002] This application relates to the technical field of household appliances, specifically to door assemblies and cooking appliances.

Background Art

[0003] In existing microwave ovens, in order to reduce microwave leakage, choke teeth are usually provided on the door. To meet the increasing requirements of users for the product appearance and improve the luxurious feeling of the product appearance, it is necessary to add a metal decorative member to the door. However, the decorative member made of a metal material is likely to shield the propagation of microwaves to the choke teeth, affect the choke effect of the choke teeth, and thereby cause an increase in the microwave leakage amount.

Summary of the Invention

Problems to be Solved by the Invention

[0004] This application aims to solve one of the technical problems in the existing technology or related technologies.

[0005] For this purpose, the first objective of this application is to provide a door assembly.

[0006] The second objective of this application is to provide a cooking appliance.

Means for Solving the Problems

[0007] To achieve at least one of the above objectives, a first aspect of the present invention provides a door assembly applicable to a cooking appliance including a kitchen, the door assembly comprising a body, a plurality of choke teeth provided on the body, each choke tooth having a choke portion facing the kitchen, and a decorative member connected to the body and configured to avoid the choke portion.

[0008] The door assembly according to this application can be applied to a cooking appliance, which includes a box, and the door assembly is movably connected to the box and can move between different positions relative to the box. The box includes a cooking chamber, which is used to store food ingredients, and the cooking appliance can cook the food ingredients in the cooking chamber. When the door assembly moves between different positions, the door assembly can open and close the cooking chamber. In a possible technical application, the cooking appliance is a microwave oven.

[0009] Furthermore, the structure of the door assembly is limited. The door assembly includes a body and a plurality of choke teeth, which are used to reduce microwave leakage from the cooking chamber. As can be understood, the door assembly is usable with a cooking appliance that has a microwave function, and when the cooking appliance is in operation, the microwave generator inside the cooking appliance radiates microwaves into the cooking chamber, and the microwaves heat the food in the cooking chamber. To reduce microwave leakage from the cooking chamber, the present invention provides a plurality of choke teeth in the door assembly. The choke teeth are provided on the body and can reduce microwave leakage from the cooking chamber.

[0010] Furthermore, the structure of the choke teeth is limited. Each choke tooth has a choke portion, which is configured to have a bent structure, allowing microwaves to propagate along the surface of the choke portion, thereby reducing microwave leakage from the cooking chamber. The choke portion is installed facing the cooking chamber, and as microwaves propagate from the cooking chamber outward, at least a portion of the microwaves propagate to the choke teeth. Because the choke portion faces the cooking chamber, microwaves can propagate along the surface of the choke portion and return to the cooking chamber in the reverse direction. As a result, the microwaves that return to the cooking chamber and the microwaves propagating outside the cooking chamber overlap and cancel each other out, reducing microwave leakage from the cooking chamber.

[0011] Furthermore, to enhance the aesthetic appearance of the door assembly, the present invention provides a decorative member to the door assembly, which is connected to the main body and exposed to the outside of the main body. In one possible technical proposal, the decorative member is made of a metal material, thereby making the appearance of the door assembly more luxurious. As can be understood, if a decorative member made of metal material shields the choke section from the cooking chamber, the metal will shield the microwaves, thereby affecting the choke effect of the choke teeth. To avoid this problem, the present invention prevents the decorative member from affecting the choke effect of the choke section by positioning the decorative member so as to avoid the choke section. In the process of microwaves propagating outside the cooking chamber, they can propagate normally to the choke section without passing through the decorative member. Therefore, the decorative member provides a decorative effect without affecting the choke effect of the choke section.

[0012] The door assembly is provided with multiple choke teeth, and the choke portion of the choke teeth is positioned facing the kitchen, so that the choke teeth can exert a choke effect against microwaves in the kitchen. The door assembly is also provided with decorative members, and the decorative members avoid the choke portion, so that the decorative members exert a decorative effect without affecting the choke effect of the choke portion.

[0013] The door assembly according to the present invention further has the following additional technical features:

[0014] The above proposed technology further includes a door provided with multiple choke teeth, and a door seal connected to the door, located on the side of the door facing the kitchen, and capable of transmitting microwaves.

[0015] This proposed technology defines the structure of the main body of the door assembly. The main body includes a door and a door seal, where the door is installed facing outwards, and a plurality of choke teeth are provided on the side of the door facing the kitchen. The door seal is connected to the door and is located on the side of the door facing the kitchen. When the door assembly closes the kitchen, the door seal is located between the door and the cookware box and contacts the box, thereby sealing the kitchen. Furthermore, the door seal allows microwaves to pass through, thereby enabling the choke teeth to perform their choke function properly. When the door assembly closes the kitchen, the door seal contacts the cookware box to seal the kitchen, and at the same time, microwaves inside the kitchen can pass through the door seal and propagate to the choke portion of the choke teeth. The choke portion properly chokes the microwaves, reducing microwave leakage from the kitchen.

[0016] In a possible technical proposal, the door seal would be made from a plastic that is permeable to microwaves.

[0017] The main unit is equipped with a door seal, and the door seal is installed to allow microwaves to pass through. This allows the cooking chamber to be sealed by the door seal, and also allows microwaves inside the cooking chamber to pass through the door seal and propagate to the choke section. The choke section then properly chokes the microwaves, reducing microwave leakage from the cooking chamber.

[0018] In the above proposed technology, the decorative components are made of metal.

[0019] This technical proposal limits the material of the decorative component. In some embodiments, the decorative component is made of metal. In this way, the appearance of the door assembly can be made more luxurious and the aesthetic appeal of the door assembly can be enhanced. Furthermore, because metal is strong, the decorative component can protect the door to some extent.

[0020] In the above proposed technology, each choke tooth further includes a connecting plate, the ends of which are connected to the choke section and the door, respectively, the connecting plate extends in a direction toward the kitchen, and the connecting plates of at least some of the choke teeth are covered by a decorative member.

[0021] This proposed technology limits the structure of the choke teeth. In some embodiments, each choke tooth further includes a connecting plate, which is used to connect the choke portion to the door. In some embodiments, one end of the connecting plate is connected to the door and the other end is connected to the choke portion, and the connecting plate extends in a direction toward the kitchen, that is, the wall surface of the connecting plate faces upward, downward and to the side of the door rather than toward the kitchen.

[0022] Furthermore, the positional relationship between the decorative member and the connecting plate is limited. In some embodiments, the decorative plate covers the connecting plate of at least some of the choke teeth among the multiple choke teeth. As can be seen, since the connecting plate extends in a direction facing the cooking chamber, it does not face the cooking chamber from the front, and shielding the connecting plate with the decorative member does not affect the choke effect of the choke teeth. In this way, the choke teeth can perform their choke action normally, and the decorative member can be attached to the main body.

[0023] In a possible design, the choke teeth are provided around the door, and multiple connecting plates for multiple choke teeth are also provided around the door, and decorative members are provided around the door and can cover all the connecting plates of the choke teeth.

[0024] In another possible technical solution, the choke teeth are provided around the door, and the plurality of connection plates of the plurality of choke teeth are also provided around the door respectively. The decorative member is provided on one side of the door, and the decorative member covers the connection plate of the choke teeth provided on one side of the door. The decorative member can cover only the top of the door, or can also cover the top and the bottom of the door at the same time.

[0025] By providing a connection plate on the choke teeth, the choke part can be connected to the door through the connection plate. Furthermore, by installing the connection plate so as to extend in the direction facing the cooking chamber, the decorative member covers the connection plate and at the same time avoids the decorative member affecting the choke effect of the choke teeth without inhibiting the propagation of microwaves in the direction of the choke part.

[0026] In the above technical solution, furthermore, the decorative member includes at least one decorative plate that covers the connection plates of at least some of the plurality of choke teeth.

[0027] In this technical solution, the structure of the decorative member is limited. In some embodiments, the decorative member includes at least one decorative plate that covers the connection plates of at least some of the plurality of choke teeth. As can be understood, the decorative member plays a role in enhancing the aesthetics of the door assembly. Therefore, the decorative plate in the decorative member can be installed at different positions on the door according to the actual needs of the product. In some embodiments, the decorative plate is provided at the top of the door and can cover the connection plate of the choke teeth provided at the top of the door. The decorative plate can be provided on both sides of the door and can also cover the connection plates of the choke teeth provided on both sides of the door. The number of decorative plates can be plural, and the plurality of decorative plates can cover the connection plates of all the choke teeth provided around the door, or can also cover the connection plates of some of the choke teeth.

[0028] In the above technical solution, when the number of decorative plates in the door assembly is plural, the door assembly further includes a connecting member for connecting two adjacent decorative plates.

[0029] In this technical solution, the structure of the decorative member is further limited. The door assembly further includes a connecting member, which is used to connect a plurality of decorative plates in the decorative member. The decorative member may have a split structure. When the number of decorative plates in the decorative member is plural, the plurality of decorative plates are connected via the connecting member. In some embodiments, the connecting member is used to connect two adjacent decorative plates.

[0030] In a possible technical solution, the connecting member is a screw.

[0031] By designing the decorative member as a split structure including a plurality of decorative plates and connecting the decorative plates via the connecting member, during the processing of the decorative member, first each individual decorative plate can be processed respectively, and then the processed decorative plates can be connected via the connecting member to form the decorative member, thereby reducing the processing difficulty.

[0032] In the above technical solution, further, when there are plural decorative plates, the plurality of decorative plates have an integral structure.

[0033] In this technical solution, another structure of the decorative member is limited. In addition to being configured as a split structure in which a plurality of decorative plates are connected to each other, the decorative member may also be configured as an integral structure composed of a plurality of decorative plates. In some embodiments, the decorative member includes a plurality of decorative plates, and the plurality of decorative plates are integrally formed. In this way, the integrity of the decorative member is improved, looseness between each decorative plate is prevented, and furthermore, in the processing process of the decorative member, the step of connecting each decorative plate becomes unnecessary, so it is possible to improve the production efficiency.

[0034] In the above technical solution, further, the door seal covers the chalk portions of a plurality of chalk teeth.

[0035] This proposed technology limits the positional relationship between the door seal and the choke teeth. The door seal covers the choke portions of the multiple choke teeth. In some embodiments, the door seal is connected to the door, is provided on the side of the door facing the cooking area, the choke teeth are provided on the door, the door seal is positioned between the choke teeth and the cooking area, the door seal can cover the choke portions of the multiple choke teeth, microwaves in the cooking area can pass through the door seal and propagate to the choke portions, the choke portions can perform their choke function properly and microwave leakage from the cooking area can be reduced.

[0036] The door seal protects the chalk teeth by covering the chalk portion of multiple chalk teeth, while the door seal is permeable to microwaves. As a result, microwaves in the cooking chamber can pass through the door seal and propagate to the chalk portion, allowing the chalk portion to perform its chalking function properly and reducing microwave leakage from the cooking chamber.

[0037] In the above proposed technology, the door seal further includes a plurality of side plates that can cover the connecting plates of at least some of the choke teeth among the plurality of choke teeth.

[0038] This proposed technology limits the structure of a door seal. The door seal includes a plurality of side plates, each extending toward the door, and when the door seal is connected to the door, the side plates can cover the connecting plates of at least some of the plurality of choke teeth. In some embodiments, the side plates can cover the connecting plates of choke teeth provided on the side of the door.

[0039] In a possible design, the decorative member includes two decorative panels, which are provided at the top and bottom of the door, respectively, and the two decorative panels cover the choke teeth connecting plates provided at the top and bottom of the door, respectively, and the side plate provided in the door seal covers the multiple choke teeth connecting plates provided on the side of the door.

[0040] The door seal is provided with multiple side plates, which protect the choke-toothed connecting plate located on the side of the door.

[0041] In the above proposed technology, the door seal further includes a mounting opening into which at least part of the door fits.

[0042] The proposed technology further defines the structure of the door seal. The door seal further includes a mounting opening, with a portion of the door protruding toward the kitchen, and the protruding portion of the door fitting into the mounting opening. In some embodiments, the protruding portion of the door can be made of a heat-resistant material, thereby allowing the door to withstand the high temperatures inside the kitchen.

[0043] Furthermore, the door assembly includes a sealing member, which is attached to the mounting opening, and at least a portion of the sealing member is positioned between the inner wall of the mounting opening and the door that enters the mounting opening. In some embodiments, the inner wall of the mounting opening and the door that enters the mounting opening press against the sealing member, thereby allowing the sealing member to exert a sealing effect.

[0044] In the above proposed technology, the door seal is further made from a plastic that is permeable to microwaves.

[0045] This proposed technology limits the material of the door seal. In some embodiments, the door seal is made of a microwave-permeable plastic, so that microwaves in the cooking chamber can pass through the door seal and propagate to the chalk teeth, which can then perform their chalking action properly.

[0046] By making the door seal from a microwave-permeable plastic, microwaves in the cooking chamber can pass through the door seal and propagate to the chalk teeth, allowing the chalk teeth to perform their chalking function properly, while also reducing the production cost of the door seal.

[0047] In the above proposed technology, multiple choke teeth are further arranged sequentially along the periphery of the door.

[0048] This proposed technology limits the placement of the choke teeth. In some embodiments, multiple choke teeth are arranged sequentially along the periphery of the door, and multiple choke teeth are installed sequentially around the door. In this way, the choke effect of the choke teeth can be improved, and microwave leakage from the cooking chamber can be further reduced.

[0049] A second aspect of the present application further provides a cooking appliance including a door assembly according to the first aspect of the present application.

[0058] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in further detail below with reference to the drawings and specific embodiments. Where there is no interference, the embodiments and features of this application can be combined with each other.

[0059] Many specific details are provided in the following description to ensure a full understanding of the present application. However, since the present application can be implemented in ways other than those described herein, the scope of protection is not limited to the specific embodiments disclosed below.

[0060] Hereinafter, several embodiments of the present invention, including a door assembly 100 and a cooking appliance, will be described with reference to Figures 1 to 5.

[0061] In one embodiment of the present invention, as shown in Figures 1, 2, and 3, the present invention provides a door assembly 100 applicable to a cooking appliance including a kitchen, the door assembly 100 including a body 110, a plurality of choke teeth 120 provided on the body 110, each choke tooth 120 having a choke portion 121 facing the kitchen, and a decorative member 130 connected to the body 110 and avoiding the choke portion 121.

[0062] The door assembly 100 according to the present invention can be applied to a cooking appliance, which includes a box, and the door assembly 100 is movably connected to the box and can move between different positions relative to the box. The box includes a cooking chamber, which is used to store food ingredients, and the cooking appliance can cook the food ingredients in the cooking chamber. When the door assembly 100 moves between different positions, the door assembly 100 can open and close the cooking chamber. In one possible embodiment, the cooking appliance is a microwave oven.

[0063] Furthermore, the structure of the door assembly 100 is limited. The door assembly 100 includes a body 110 and a plurality of choke teeth 120, the choke teeth 120 being used to reduce microwave leakage from the cooking chamber. As can be understood, the door assembly 100 is usable with cooking appliances that have microwave functionality. When the cooking appliance is in operation, the microwave generator inside the cooking appliance radiates microwaves into the cooking chamber, and the microwaves heat the food in the cooking chamber. To reduce microwave leakage from the cooking chamber, the door assembly 100 is provided with a plurality of choke teeth 120. The choke teeth 120 are provided on the body 110, and the choke teeth 120 can reduce microwave leakage from the cooking chamber.

[0064] Furthermore, the structure of the choke teeth 120 is limited. Each choke tooth 120 has a choke portion 121, which is configured to have a bent structure, allowing microwaves to propagate along the surface of the choke portion 121, thereby reducing microwave leakage from the cooking chamber. The choke portion 121 is installed facing the cooking chamber, and in the process of microwaves propagating out of the cooking chamber, at least a portion of the microwaves propagate to the choke teeth 120. Because the choke portion 121 faces the cooking chamber, the microwaves can propagate along the surface of the choke portion 121 and return to the cooking chamber in the opposite direction. As a result, the microwaves that return to the cooking chamber and the microwaves propagating outside the cooking chamber overlap and cancel each other out, reducing microwave leakage from the cooking chamber.

[0065] Furthermore, to enhance the appearance of the door assembly 100, the present invention provides a decorative member 130 to the door assembly 100, which is connected to the main body 110 and exposed to the outside of the main body 110. In one possible embodiment, the decorative member 130 is made of a metal material, thereby making the appearance of the door assembly 100 more luxurious. As can be understood, if the decorative member 130 made of a metal material shields the choke section 121 from the cooking chamber, the metal will shield the microwaves, thereby affecting the choke effect of the choke teeth 120. To avoid this problem, the present invention prevents the decorative member 130 from affecting the choke effect of the choke section 121 by positioning the decorative member 130 to avoid the choke section 121. In the process of microwaves propagating outside the cooking chamber, they can propagate normally to the choke section 121 without passing through the decorative member 130. Therefore, the decorative member 130 provides a decorative effect without affecting the choke effect of the choke section 121.

[0066] The door assembly 100 is provided with multiple choke teeth 120, and the choke portion 121 of the choke teeth 120 is installed facing the kitchen, so that the choke teeth 120 can exert a choke effect against microwaves in the kitchen. The door assembly 100 is also provided with a decorative member 130, and the decorative member 130 avoids the choke portion 121, so that the decorative member 130 exerts a decorative effect without affecting the choke effect of the choke portion 121.

[0067] In one embodiment of the present invention, as shown in Figures 1 and 3, the main body 110 includes a door 111 provided with a plurality of choke teeth 120, and a door seal 112 connected to the door 111, located on the side of the door 111 facing the kitchen, and capable of transmitting microwaves.

[0068] In this embodiment, the structure of the main body 110 in the door assembly 100 is limited. The main body 110 includes a door 111 and a door seal 112, where the door 111 is installed facing outwards, and a plurality of choke teeth 120 are provided on the side of the door 111 facing the kitchen. The door seal 112 is connected to the door 111 and is located on the side of the door 111 facing the kitchen. When the door assembly 100 closes the kitchen, the door seal 112 is located between the door 111 and the cookware box and contacts the box, thereby sealing the kitchen. Furthermore, the door seal 112 transmits microwaves, thereby allowing the choke teeth 120 to perform their choke function properly. When the door assembly 100 closes the kitchen, the door seal 112 contacts the cookware box to seal the kitchen, and at the same time, microwaves inside the kitchen can pass through the door seal 112 and propagate to the choke portion 121 of the choke teeth 120. The choke section 121 effectively chokes the microwaves, reducing microwave leakage from the cooking chamber.

[0069] In one possible embodiment, the door seal 112 is made from a plastic that is permeable to microwaves.

[0070] The main body 110 is provided with a door seal 112, and the door seal 112 is installed to allow microwaves to pass through. As a result, the cooking chamber can be sealed by the door seal 112, and microwaves in the cooking chamber can pass through the door seal 112 and propagate to the choke section 121. The choke section 121 can then properly choke the microwaves, reducing microwave leakage from the cooking chamber.

[0071] In one embodiment of the present invention, the decorative member 130 is made of a metal material.

[0072] In this embodiment, the material of the decorative member 130 is limited. In some embodiments, the decorative member 130 is made of a metal material. In this way, the appearance of the door assembly 100 can be made more luxurious and the aesthetic appeal of the door assembly 100 can be enhanced. Furthermore, because metal materials have high strength, the decorative member 130 can also protect the door 111 to some extent.

[0073] In one embodiment of the present invention, as shown in Figures 1, 3, and 5, each choke tooth 120 includes a connecting plate 122, the ends of which are connected to the choke portion 121 and the door 111 respectively, the connecting plate 122 extends in a direction toward the kitchen, and the connecting plates 122 of at least some of the choke teeth 120 are covered by a decorative member 130.

[0074] In this embodiment, the structure of the choke teeth 120 is limited. In some embodiments, each choke tooth 120 further includes a connecting plate 122, which is used to connect the choke portion 121 to the door 111. In some embodiments, one end of the connecting plate 122 is connected to the door 111 and the other end is connected to the choke portion 121, and the connecting plate 122 extends in a direction toward the kitchen, that is, the wall surface of the connecting plate 122 faces upward, downward and to the side of the door 111 rather than toward the kitchen.

[0075] Furthermore, the positional relationship between the decorative member 130 and the connecting plate 122 is limited. In some embodiments, the decorative plate 131 covers the connecting plate 122 of at least some of the choke teeth 120. As can be seen, since the connecting plate 122 extends in a direction facing the cooking chamber, the connecting plate 122 does not face the cooking chamber from the front, and shielding the connecting plate 122 with the decorative member 130 does not affect the choke effect of the choke teeth 120. In this way, the choke teeth 120 can perform their choke function normally, and the decorative member 130 can be attached to the main body 110.

[0076] As shown in Figure 1, in one possible embodiment, the choke teeth 120 are provided around the door 111, and the multiple connecting plates 122 of the multiple choke teeth 120 are also provided around the door 111, and the decorative member 130 is provided around the door 111 and can cover all the connecting plates 122 of the choke teeth 120.

[0077] As shown in Figure 3, in another possible embodiment, the choke teeth 120 are provided around the door 111, and multiple connecting plates 122 of the multiple choke teeth 120 are also provided around the door 111, and a decorative member 130 is provided on one side of the door 111, and the decorative member 130 covers the connecting plates 122 of the choke teeth 120 provided on one side of the door 111. The decorative member 130 can cover only the top of the door 111, or it can cover both the top and bottom of the door 111 at the same time.

[0078] By providing a connecting plate 122 on the choke teeth 120, the choke section 121 can be connected to the door 111 via the connecting plate 122. Furthermore, by installing the connecting plate 122 so as to extend toward the kitchen, the decorative member 130 covers the connecting plate 122 while simultaneously preventing the decorative member 130 from affecting the choke effect of the choke teeth 120 without obstructing the propagation of microwaves toward the choke section 121.

[0079] In one embodiment of the present invention, as shown in Figures 1, 2, and 3, the decorative member 130 includes at least one decorative plate 131 that covers the connecting plates 122 of at least some of the choke teeth 120 among the plurality of choke teeth 120.

[0080] In this embodiment, the structure of the decorative member 130 is limited. In some embodiments, the decorative member 130 includes at least one decorative plate 131 that covers the connecting plates 122 of at least some of the choke teeth 120 among a plurality of choke teeth 120. As can be understood, the decorative member 130 serves to enhance the aesthetics of the door assembly 100. Accordingly, the decorative plates 131 in the decorative member 130 can be installed in different locations on the door 111 according to the actual needs of the product. In some embodiments, as shown in Figure 3, the decorative plate 131 may be provided at the top of the door 111 and cover the connecting plates 122 of the choke teeth 120 provided at the top of the door 111. The decorative plate 131 may also be provided on both sides of the door 111 and cover the connecting plates 122 of the choke teeth 120 provided on both sides of the door 111. The number of decorative panels 131 may be multiple, and multiple decorative panels 131 can cover all the connecting plates 122 of the choke teeth 120 provided around the door 111, or they can cover some of the connecting plates 122 of the choke teeth 120.

[0081] In one embodiment of the present invention, the door assembly 100 further includes a connecting member for connecting two adjacent decorative panels 131 when there are multiple decorative panels 131.

[0082] In this embodiment, the structure of the decorative member 130 is further limited. The door assembly 100 further includes a connecting member, which is used to connect multiple decorative panels 131 in the decorative member 130. As shown in Figure 1, the decorative member 130 may have a segmented structure. When there are multiple decorative panels 131 in the decorative member 130, the multiple decorative panels 131 are connected via the connecting member. In some embodiments, the connecting member is used to connect two adjacent decorative panels 131.

[0083] In one possible embodiment, the connecting member is a screw.

[0084] By designing the decorative member 130 as a segmented structure including multiple decorative panels 131, and connecting the decorative panels 131 via connecting members, the individual decorative panels 131 can be processed first during the manufacturing process of the decorative member 130, and then the processed decorative panels 131 can be connected via connecting members to form the decorative member 130, thereby reducing the difficulty of manufacturing.

[0085] In one embodiment of the present invention, as shown in Figure 2, when there are multiple decorative plates 131, the multiple decorative plates 131 have an integrated structure.

[0086] In this embodiment, we limit the structure of the decorative member 130 to another structure.

[0097] In one embodiment of the present invention, the door seal 112 is made of a microwave-transmitting plastic.

[0098] In this embodiment, the material of the door seal 112 is limited. In some embodiments, the door seal 112 is made of a microwave-permeable plastic so that microwaves in the cooking chamber can pass through the door seal 112 and propagate to the choke teeth 120, which can then perform their choke function properly.

[0099] By making the door seal 112 from a microwave-permeable plastic, microwaves in the cooking chamber can pass through the door seal 112 and propagate to the choke teeth 120, allowing the choke teeth 120 to perform their choke function properly, while also reducing the production cost of the door seal 112.

[0100] In one embodiment of the present invention, as shown in Figures 1, 3, 4, and 5, a plurality of choke teeth 120 are arranged sequentially along the periphery of the door 111.

[0101] In this embodiment, the installation position of the choke teeth 120 is limited. In some embodiments, multiple choke teeth 120 are arranged sequentially along the periphery of the door 111, and multiple choke teeth 120 are installed sequentially around the door 111. In this way, the choke effect of the choke teeth 120 can be improved, and microwave leakage from the cooking chamber can be further reduced.
