Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a box assembly and cooking equipment. Background Art

[0002] At present, kitchen appliances such as ovens usually generate a lot of heat during use. The air in the space behind the oven will be heated by the heat conducted from the cavity. The hot air will rise due to its density and enter the electrical room. In the related art, a heat dissipation fan is added to the electrical room to dissipate the heat of the heating elements in the electrical room. However, since the air inhaled by the heat dissipation fan is already heated hot air, the heat dissipation effect is very poor and the temperature rise of the electrical components in the electrical room cannot be reduced. Utility Model Content

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

[0004] In view of this, an embodiment of a first aspect of the present invention provides a box assembly.

[0005] An embodiment of a second aspect of the present invention provides a cooking device.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a box assembly, including: a cover body, a cooking box body is arranged in the cover body, a device cavity is formed between the cooking box body and the cover body, and a cooking cavity is formed in the cooking box body; an air guide plate is arranged in the equipment cavity, the air guide plate is used to separate the equipment cavity to form a device cavity and a heat dissipation cavity, the heat dissipation cavity is connected with the cooking cavity, and at least one heating element is arranged in the device cavity; wherein the air in the device cavity is not connected with the air in the heat dissipation cavity.

[0007] The box assembly proposed by the utility model includes a cover body, a cooking box body and an air guide plate. The cover body serves as an integral outer shell, and the cooking box body serves as an internal space actually used for cooking. An equipment cavity is formed between the outer side of the cover body and the inner side of the cover body. By arranging an air guide plate in the equipment cavity, the equipment cavity can be divided into a device cavity and a heat dissipation cavity. Under the action of the air guide plate, it can be ensured that the air in the device cavity is not connected with the air in the heat dissipation cavity, thereby ensuring that the air flow in the device cavity is strictly controlled to prevent hot air from affecting the heat dissipation effect.

[0008] Furthermore, the equipment cavity is the space formed between the cooking box body and the cover body, which is used to accommodate various electrical components or heat dissipation components. The device cavity is the part separated by the air guide plate, which accommodates one or more heating elements. The heat dissipation cavity is another part of the equipment cavity except the device cavity, which is connected with the cooking cavity, and can conduct the heat generated in the cooking cavity to the heat dissipation cavity to achieve heat dissipation.

[0009] It can be understood that the separation design ensures that the air in the heat dissipation cavity and the device cavity are not connected, improves the overall heat dissipation efficiency, optimizes the oven heat dissipation system, and reduces the temperature rise of electrical components caused by hot air backflow. Through a series of design improvements, the flow path of hot air is effectively controlled, and the efficiency of the heat dissipation fan is improved, thereby protecting the inverter, display panel and other heating components and extending their service life.

[0010] In some technical solutions, optionally, one side of the air guide plate is connected to the outer wall of the cooking box; the other side of the air guide plate extends toward the rear wall of the cover, and the shape of the side is adapted to the shape of the rear wall of the cover.

[0011] In this technical solution, the specific setting position of the air guide plate is restricted, that is, one side of the air guide plate is tightly connected to the outer wall of the cooking box to ensure that the air guide plate is firmly fixed and plays the role of separating the equipment cavity, and the other side of the air guide plate extends toward the rear wall of the cover, and the shape of the side extending toward the rear wall is adapted to the shape of the rear wall of the cover, that is, one end of the air guide plate is connected to the outer wall of the cooking box, and the other end extends to the rear wall close to the cover. The shape of the air guide plate is adapted to the shape of the rear wall of the cover, which can effectively close the connection gap between the heat dissipation cavity and the device cavity, further reducing the risk of hot air flowing into the device cavity.

[0012] The air guide plate serves to separate the equipment cavity between the cooking box and the rear wall of the cover, dividing the equipment cavity into a device cavity and a heat dissipation cavity. By separating the equipment cavity into the device cavity and the heat dissipation cavity, the air guide plate ensures the independence of the air flow of the two parts, preventing hot air from entering the device cavity.

[0013] In some technical solutions, optionally, it also includes: a seal, which is arranged on the air guide plate, and is used to seal the gap between the air guide plate and the rear wall of the cover body.

[0014] In this technical solution, a seal is arranged on the air guide plate, specifically at the contact edge between the air guide plate and the rear wall of the cover body. By fixing the seal on the edge of the air guide plate, the seal is located in the contact area between the air guide plate and the rear wall of the cover body, specifically at the side where the air guide plate extends to the rear wall of the cover body, ensuring that it can effectively cover the gap between the air guide plate and the rear wall of the cover body, preventing hot air from entering the device cavity through the gap, thereby maintaining the low temperature of the air in the device cavity. Of course, it also reduces the entry of hot air into the device cavity, reduces the temperature rise of the electrical device, and effectively protects the working environment and stability of the electrical device.

[0015] At the same time, by adding seals to the edge of the air guide plate, the sealing of the entire cooling system is further improved, ensuring that the circulation path of the cold air is not disturbed.

[0016] In some technical solutions, optionally, the seal is bonded to the rear wall of the cover body, and / or the seal is bonded to the air guide plate.

[0017] In this technical solution, the sealing member can be selectively connected to at least one of the rear wall of the cover body and the wind guide plate by bonding, which can improve the connection strength on the one hand and improve the sealing performance by bonding on the other hand.

[0018] It is understood that when the seal is bonded only to the rear wall, it needs to fit tightly with the air guide plate to ensure sealing. Similarly, when the seal is bonded only to the air guide plate, it needs to fit tightly with the rear wall to minimize the gap that may exist at the non-bonded joint, thereby improving the sealing effect.

[0019] Of course, the bonding between the seal and the rear wall can be achieved by any means such as solid glue, liquid glue, or light-curing glue, and the bonding between the seal and the air guide plate can be achieved by any means such as solid glue, liquid glue, or light-curing glue.

[0020] In some technical solutions, optionally, the sealing member is in the shape of a strip, and the material of the sealing member includes sponge and / or rubber.

[0021] In this solution, by limiting the seal to be strip-shaped, the encroachment on the internal space can be reduced, and the strip-shaped seal can meet the sealing of the gap between the rear wall and the air guide plate, thereby ensuring the utilization rate of the internal space. In addition, the seal can be made of sponge, or made of rubber, or processed with a combination of sponge and rubber.

[0022] In some technical solutions, optionally, the device cavity is arranged above the heat dissipation cavity, a take-in and put-out port is arranged at the front side of the cooking cavity, and the heat dissipation cavity is arranged at the rear side of the cooking cavity.

[0023] In this technical solution, the device cavity is arranged above the heat dissipation cavity. In the case of this relative position, if no air guide plate is provided, the heat will more easily flow into the device cavity due to its own density, affecting normal heat dissipation. In view of the above positional relationship, an air guide plate is provided to isolate the hot air flowing into the device cavity, thereby ensuring that the air temperature in the device cavity is lower than the air temperature in the heat dissipation cavity.

[0024] In addition, a loading and unloading port is provided on the front side of the cooking cavity, which is convenient for users to put food in and take out the cooking cavity. At the same time, the heat dissipation cavity is located on the rear side of the cooking cavity and is connected to the cooking cavity, which helps to guide the heat generated during the cooking process to the heat dissipation cavity.

[0025] In some technical solutions, optionally, it also includes: a first fan, arranged in the device cavity; a partition, arranged at the air outlet of the first fan, and the partition is against the wall of the cover body; wherein the heating element is arranged on one side of the partition, and the air generated by the operation of the first fan flows through the heating element.

[0026] In this technical solution, the first fan is arranged in the device cavity, responsible for generating air flow in the device cavity, helping to dissipate heat and maintaining the temperature of the heating element within a safe range. The partition is arranged at the air outlet of the first fan. The partition not only serves as a part of the air outlet of the first fan, but also contacts with the wall of the cover body, which helps to form a stable airflow channel. At the same time, it also serves to isolate the device cavity and the heat dissipation cavity to a certain extent, ensuring the directionality of the air flow.

[0027] In addition, the heating element is arranged on one side of the partition, that is, the side opposite to the air outlet of the first fan. The heating element generates heat when working, and the air generated by the first fan flows through the heating element, taking away the heat to achieve heat dissipation.

[0028] The air flow generated by the first fan flows directly through the heating element to achieve targeted heat dissipation and improve heat dissipation efficiency. The design of the partition helps to control the direction of air flow, ensuring that the air flow can effectively cover the heating element and take away the heat.

[0029] This design achieves effective heat management and protection of electrical components inside the oven by rationally arranging the first fan and partitions, as well as the location of the heating elements. The air flow of the first fan directly acts on the heating elements, improving heat dissipation efficiency. The design of the partitions not only controls the direction of air flow, but also optimizes the thermal management and space utilization inside the oven.

[0030] In some technical solutions, optionally, one end of the heat dissipation cavity is connected to one end of the device cavity, and in the height direction of the cover body, the air guide plate is arranged below the first fan.

[0031] In this technical solution, one end of the heat dissipation cavity is connected to one end of the device cavity to form a continuous airflow channel. The air guide plate is located below the first fan and adjacent to the device cavity. The air guide plate can guide the airflow sucked by the first fan and ensure that the air does not flow into the heat dissipation cavity, thereby ensuring the heat dissipation efficiency of the heating element.

[0032] In some technical solutions, optionally, it also includes: a first port, which is arranged on the wall surface of the cover body corresponding to one end of the device cavity close to the heat dissipation cavity; a second port, which is arranged on the wall surface of the cover body corresponding to one end of the device cavity away from the heat dissipation cavity.

[0033] In this technical solution, the first port is provided in the cover body, corresponding to the wall surface of one end of the device cavity close to the heat dissipation cavity, and the second port corresponds to the wall surface of one end of the device cavity away from the heat dissipation cavity. The first port and the second port can be used as the air inlet and outlet respectively, so as to achieve heat dissipation of the components in the device cavity. Specifically, the first port, as the inlet of cold air, helps to reduce the temperature of the device cavity, and the second port, as the outlet of hot air, helps to maintain the temperature balance in the device cavity. The cold air enters the device cavity through the first port, is sucked in and accelerated by the first fan, takes away the heat generated by the electrical device, and then is discharged through the second port to form an internal circulation.

[0034] Likewise, the first port can also serve as an outlet for hot air, and the second port can serve as an inlet for cold air.

[0035] In some technical solutions, optionally, it also includes: a third port, which is arranged on the wall of the cover body corresponding to the end of the heat dissipation cavity away from the device cavity; wherein, when the first fan rotates, air flows in from the first port.

[0036] In this technical solution, the first port is defined as the inlet, and a third port is provided at the end of the heat dissipation cavity away from the device cavity, so that the exhaust port of the heat dissipation cavity and the inlet of the device cavity are arranged as far away as possible, and the hot air in the heat dissipation cavity is discharged to the outside of the oven to prevent the hot air from flowing back to the device cavity.

[0037] It can be understood that the air flows into the device cavity from the first port, is accelerated by the first fan, flows through the device cavity, takes away the heat from the heating element, and then is discharged through the second port, forming an airflow circulation in the device cavity. On this basis, with the isolation effect of the guide plate and the airflow circulation of the first fan, the electrical device is effectively cooled, avoiding overheating problems and extending the service life of the electrical device. At the same time, the setting of the third port helps to quickly discharge the hot air in the heat dissipation cavity.

[0038] In some technical solutions, optionally, it also includes: a second fan, which is arranged in the heat dissipation cavity, and the heat resistance of the material of the second fan is higher than the heat resistance of the material of the first fan.

[0039] In this technical solution, since the heat dissipation cavity is connected to the cooking cavity, the interior of the heat dissipation cavity is mainly used to discharge a large amount of heat generated by the cooking cavity, so there is a certain requirement for the heat resistance of the second fan in the heat dissipation cavity. In other words, under the action of the air guide plate of the present application, the ambient temperature of the first fan is significantly lower than that of the second fan, so the heat resistance requirement for the first fan is also reduced, and lower-cost materials can be used for manufacturing and production. The material of the second fan has higher heat resistance than that of the first fan to adapt to the high temperature environment in the heat dissipation cavity. When the second fan is running, it can generate airflow in the heat dissipation cavity, help to more effectively discharge hot air, and prevent hot air from accumulating in the heat dissipation cavity.

[0040] An embodiment of the second aspect of the present application provides a cooking device, comprising: any of the above-mentioned box assemblies, wherein the front side of the cooking cavity in the box assembly is provided with a take-in / put-out opening; and a door body movably connected to the box assembly to open and close the take-in / put-out opening.

[0041] The cooking device provided in the present application includes a movably connected box body assembly and a door body, and the door body can open and close the access opening on the front side of the cooking cavity by opening and closing, so that the user can put in or take out the food.

[0042] It should be added that, since the cooking device provided in the present application includes any of the above-mentioned box assemblies, it has the beneficial effects of any of the above-mentioned box assemblies, which will not be repeated here.

[0043] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0053] Refer to the following Figures 1 to 4 Some embodiments according to the present invention are described.

[0054] like Figure 1 As shown, a box assembly 100 proposed in this embodiment includes a cover body 102, a cooking box body 1022 and an air guide plate 104. The cover body 102 serves as an integral outer shell, and the cooking box body 1022 serves as an internal space actually used for cooking. An equipment cavity 1032 is formed between the outer side thereof and the inner side of the cover body 102. By arranging the air guide plate 104 in the equipment cavity 1032, the equipment cavity 1032 can be divided into a device cavity 1034 and a heat dissipation cavity 1036. Under the action of the air guide plate 104, it can be ensured that the air in the device cavity 1034 is not connected with the air in the heat dissipation cavity 1036, thereby ensuring that the air flow in the device cavity 1034 is strictly controlled to prevent hot air from affecting the heat dissipation effect.

[0055] Furthermore, the equipment cavity 1032 is a space formed between the cooking box body 1022 and the cover body 102, which is used to accommodate various electrical components or heat dissipation components. The device cavity 1034 is a part separated by the air guide plate 104, which accommodates one or more heating elements 106. The heat dissipation cavity 1036 is another part of the equipment cavity 1032 except the device cavity 1034, which is connected to the cooking cavity 1024, and can conduct the heat generated in the cooking cavity 1024 to the heat dissipation cavity 1036 to achieve heat dissipation.

[0056] It can be understood that the separation design ensures that the air in the heat dissipation cavity 1036 and the device cavity 1034 are not connected, thereby improving the overall heat dissipation efficiency, optimizing the oven heat dissipation system, and reducing the temperature rise of electrical components caused by hot air backflow. Through a series of design improvements, the flow path of hot air is effectively controlled, the efficiency of the heat dissipation fan is improved, thereby protecting the heat generating components 106 such as the inverter and the display panel and extending their service life.

[0057] In some embodiments, the specific setting position of the air guide plate 104 is optionally restricted, that is, one side of the air guide plate 104 is tightly connected to the outer wall of the cooking box 1022 to ensure that the air guide plate 104 is firmly fixed to play the role of separating the device cavity 1032, and the other side of the air guide plate 104 extends toward the rear wall 103 of the cover 102, and the shape of the side extending toward the rear wall is adapted to the shape of the rear wall 103 of the cover 102, that is, one end of the air guide plate 104 is connected to the outer wall of the cooking box 1022, and the other end extends to the rear wall 103 close to the cover 102. The shape of the air guide plate 104 is adapted to the shape of the rear wall 103 of the cover 102, which can effectively close the connection gap between the heat dissipation cavity 1036 and the device cavity 1034, and further reduce the risk of hot air flowing into the device cavity 1034.

[0058] The air guide plate 104 serves to separate the equipment cavity 1032 between the cooking box body 1022 and the rear wall 103 of the cover body 102, and divides the equipment cavity 1032 into a device cavity 1034 and a heat dissipation cavity 1036. By dividing the equipment cavity 1032 into the device cavity 1034 and the heat dissipation cavity 1036, the air guide plate 104 ensures the independence of the air flow of the two parts, and prevents hot air from entering the device cavity 1034.

[0059] In some embodiments, optionally, the seal 108 is disposed on the air guide plate 104, specifically at the contact edge between the air guide plate 104 and the rear wall 103 of the cover body 102. By fixing the seal 108 on the edge of the air guide plate 104, the seal 108 is located in the contact area between the air guide plate 104 and the rear wall 103 of the cover body 102, specifically at the side where the air guide plate 104 extends to the rear wall 103 of the cover body 102, ensuring that it can effectively cover the gap between the air guide plate 104 and the rear wall 103 of the cover body 102, preventing hot air from entering the device cavity 1034 through the gap, thereby maintaining the low temperature of the air in the device cavity 1034, and of course, reducing the entry of hot air into the device cavity 1034, thereby reducing the temperature rise of the electrical device and effectively protecting the working environment and stability of the electrical device.

[0060] At the same time, by adding a seal 108 to the edge of the air guide plate 104, the sealing performance of the entire heat dissipation system is further improved, ensuring that the flow path of the cold air is not disturbed.

[0061] Furthermore, the seal 108 can be selectively connected to at least one of the rear wall 103 of the cover body 102 and the air guide plate 104 by bonding, which can improve the connection strength on the one hand and improve the sealing performance through bonding on the other hand.

[0062] It is understood that when the seal 108 is bonded only to the rear wall 103, it needs to be tightly fitted with the air guide plate 104 to ensure sealing. Similarly, when the seal 108 is bonded only to the air guide plate 104, it needs to be tightly fitted with the rear wall 103 to minimize the gap that may exist at the non-bonded connection, thereby improving the sealing effect.

[0063] Of course, the bonding between the seal 108 and the rear wall 103 can be achieved by any means such as solid glue, liquid glue, or light-curing glue, and the bonding between the seal 108 and the air guide plate 104 can be achieved by any means such as solid glue, liquid glue, or light-curing glue.

[0064] By limiting the seal 108 to be strip-shaped, the encroachment on the internal space can be reduced, and the strip-shaped seal 108 can meet the sealing of the gap between the rear wall 103 and the air guide plate 104, thereby ensuring the utilization rate of the internal space. In addition, the seal 108 can be made of sponge, or made of rubber, or processed with a combination of sponge and rubber.

[0065] Furthermore, the sealing member 108 may be a sponge strip.

[0066] In a specific embodiment, the device cavity 1034 is arranged above the heat dissipation cavity 1036. In this relative position, if the air guide plate 104 is not provided, the heat will more easily flow into the device cavity 1034 due to its own density, affecting normal heat dissipation. In view of the above positional relationship, the air guide plate 104 is provided to isolate the hot air flowing into the device cavity 1034, thereby ensuring that the air temperature in the device cavity 1034 is lower than the air temperature in the heat dissipation cavity 1036.

[0067] In addition, if Figure 2 As shown, a loading and unloading port 1026 is provided on the front side of the cooking cavity 1024 to facilitate the user to put food in and take food out of the cooking cavity 1024. At the same time, the heat dissipation cavity 1036 is located on the rear side of the cooking cavity 1024 and is connected to the cooking cavity 1024, which helps to guide the heat generated during the cooking process to the heat dissipation cavity 1036.

[0068] In a specific embodiment, optionally, the first fan 1102 is disposed in the device cavity 1034, responsible for generating air flow in the device cavity 1034, helping to dissipate heat and maintaining the temperature of the heating element 106 within a safe range, and the partition 1104 is disposed at the air outlet 1103 of the first fan 1102. The partition 1104 not only serves as a part of the air outlet of the first fan 1102, but also contacts the wall of the cover body 102, which helps to form a stable airflow channel. At the same time, it also serves to isolate the device cavity 1034 and the heat dissipation cavity 1036 to a certain extent, ensuring the directionality of the air flow.

[0069] In addition, the heating element 106 is arranged on one side of the partition 1104, that is, the side opposite to the air outlet of the first fan 1102. The heating element 106 generates heat when working. The air generated by the first fan 1102 flows through the heating element 106, taking away the heat to achieve heat dissipation.

[0070] The air flow generated by the first fan 1102 flows directly through the heating element 106 to achieve targeted heat dissipation and improve heat dissipation efficiency. The design of the partition 1104 helps to control the direction of air flow and ensure that the air flow can effectively cover the heating element 106 and take away heat.

[0071] This design achieves effective heat management and protection of electrical components inside the oven by rationally arranging the first fan 1102 and the partition 1104, as well as the position of the heating element 106. The air flow of the first fan 1102 directly acts on the heating element 106, thereby improving the heat dissipation efficiency. The design of the partition 1104 not only controls the direction of air flow, but also optimizes the thermal management and space utilization inside the oven.

[0072] In a specific embodiment, one end of the heat dissipation cavity 1036 is optionally connected to one end of the device cavity 1034 to form a continuous airflow channel. It can be understood that the structure formed by the heat dissipation cavity 1036 and the device cavity 1034 can be V-shaped, L-shaped or other shapes with the ends connected according to the different angles between the two. The air guide plate 104 is located below the first fan 1102 and adjacent to the device cavity 1034. The air guide plate 104 can guide the airflow sucked by the first fan 1102 and ensure that the air does not flow into the heat dissipation cavity 1036, thereby ensuring the heat dissipation efficiency of the heating element 106.

[0073] In a specific embodiment, optionally, the first port 1122 is provided in the cover body 102, corresponding to the wall surface of one end of the device cavity 1034 close to the heat dissipation cavity 1036, and the second port 1124 corresponds to the wall surface of one end of the device cavity 1034 away from the heat dissipation cavity 1036. The first port 1122 and the second port 1124 can be used as the inlet and outlet of air respectively, so as to achieve heat dissipation of the components in the device cavity 1034. Specifically, the first port 1122, as the inlet of cold air, helps to reduce the temperature of the device cavity 1034, and the second port 1124, as the outlet of hot air, helps to maintain the temperature balance in the device cavity 1034. The cold air enters the device cavity 1034 through the first port 1122, is sucked in and accelerated by the first fan 1102, takes away the heat generated by the electrical device, and then is discharged through the second port 1124 to form an internal circulation.

[0074] Likewise, the first port 1122 may also serve as an outlet for hot air, and the second port 1124 may serve as an inlet for cold air.

[0075] In a specific embodiment, optionally, Figure 2 and Figure 3 As shown, the first port 1122 is defined as the inlet, and a third port 114 is provided at one end of the heat dissipation cavity 1036 away from the device cavity 1034, so that the exhaust port of the heat dissipation cavity 1036 and the inlet of the device cavity 1034 are arranged as far away as possible, and the hot air in the heat dissipation cavity 1036 is discharged to the outside of the oven, preventing the hot air from flowing back to the device cavity 1034.

[0076] It can be understood that the air flows into the device cavity 1034 from the first port 1122, is accelerated by the first fan 1102, flows through the device cavity 1034, takes away the heat on the heating element 106, and then is discharged through the second port 1124, forming an airflow circulation in the device cavity 1034. On this basis, with the isolation effect of the guide plate and the airflow circulation of the first fan 1102, the electrical device is effectively cooled, the overheating problem is avoided, and the service life of the electrical device is extended. At the same time, the setting of the third port 114 helps to quickly discharge the hot air in the heat dissipation cavity 1036.

[0077] Air flow direction Figure 2 Indicated by arrow.

[0078] In some embodiments, optionally, since the heat dissipation cavity 1036 is connected to the cooking cavity 1024, the interior thereof is mainly used to discharge a large amount of heat generated by the cooking cavity 1024, so there is also a certain requirement for the heat resistance of the second fan 116 in the heat dissipation cavity 1036. In other words, under the action of the air guide plate 104 of the present application, the ambient temperature of the first fan 1102 is significantly lower than that of the second fan 116, so the heat resistance requirement for the first fan 1102 is also reduced, and a lower-cost material can be used for manufacturing and production. The material of the second fan 116 has a higher heat resistance than that of the first fan 1102 to adapt to the high temperature environment in the heat dissipation cavity 1036. When the second fan 116 is running, it can generate airflow in the heat dissipation cavity 1036, which helps to more effectively discharge hot air and prevent hot air from accumulating in the heat dissipation cavity 1036.

[0079] Another embodiment of the present application provides a cooking device 200, such as Figure 4 As shown, it includes a box assembly 100 and a door body 202 that are movably connected. The door body 202 can open and close the access opening 1026 on the front side of the cooking cavity 1024 to facilitate users to put in or take out food.

[0080] The cooking device 200 may specifically be an oven, a baking oven, a microwave oven or other cooking device 200 that can cook food and has heat dissipation requirements.

[0081] It should be added that, since the cooking device 200 provided in the present application includes any of the above-mentioned box assemblies 100, it has the beneficial effects of any of the above-mentioned box assemblies 100, which will not be repeated here.

[0082] In a specific embodiment, an oven is proposed, wherein the edge where the air guide bottom plate (i.e., the air guide plate) is connected to the rear outer cover (i.e., the rear wall of the cover body) is contoured according to the shape of the rear outer cover to reduce the gap between the air guide bottom plate and the rear outer cover; there is still a risk of air leakage between the air guide bottom plate and the rear outer cover due to the deformation and assembly gap of the rear outer cover. In order to reduce the gap and reduce air leakage, a sponge strip (i.e., a seal) is added to the edge where the air guide bottom plate contacts the rear outer cover to prevent the hot air between the rear outer cover and the support plate from entering the electrical room (i.e., the device cavity); a partition is arranged in the electrical room, and an air inlet (i.e., a first port) is arranged on the upper part of the rear outer cover. Under the constraints of the partition, the air guide bottom plate and the rear outer cover, the fan can only inhale cold air from the air inlet of the rear outer cover, and will not inhale the hot air in the lower part between the support plate and the rear outer cover; the electrical components arranged between the support plate and the rear outer cover, such as the hot air motor, have high heat resistance and will not exceed the temperature rise standard due to the blockage of the gap between the air guide bottom plate and the rear outer cover and the reduction of air circulation.

[0083] According to the box assembly and cooking equipment provided by the utility model, the air guide plate can ensure that the air in the device cavity is not connected to the air in the heat dissipation cavity, thereby ensuring that the air flow in the device cavity is strictly controlled to prevent hot air from affecting the heat dissipation effect.
