Description

Technical Field

[0001] This application claims the priority of a Chinese patent application with the application number "202310795422.1" and the application title "Cooking Box and Cooking Appliance", which was filed with the China Patent Office on June 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, and specifically, to cooking boxes and cooking appliances.

Background Art

[0003] In existing cooking appliances with an air fryer function, the air fryer assembly usually occupies a large mounting space, so the volume of the cooking appliance becomes large and the product structure is not compact.

Summary of 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 cooking box.

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

[0007] To achieve at least one of the above objectives, the first aspect of this application provides a cooking box, which includes a main body including a cooking chamber and an air fryer assembly for blowing hot air into the cooking chamber. A plurality of accommodation grooves are provided on the wall surface of the main body, and at least a part of the accommodation grooves are recessed in the direction towards the cooking chamber, and at least a part of the air fryer assembly is located in the accommodation grooves recessed in the direction towards the cooking chamber.

[0008] The cooking box according to this application is applicable to cooking appliances, and the cooking box includes a main body, the main body includes a cooking chamber, the cooking chamber is used to contain food ingredients, and when the cooking appliance is in operation, the cooking appliance cooks the food ingredients in the cooking chamber.

[0009] Furthermore, the cooking box includes an air fryer assembly, which can cook food in the cooking chamber using an air fryer method. In some embodiments, when the air fryer assembly is in operation, it can blow hot air into the cooking chamber, thereby heating the food in the cooking chamber via the hot air and achieving the cooking effect of an air fryer. The air fryer assembly is composed of multiple members, thereby having a certain thickness. To reduce the height to which the air fryer assembly protrudes from the outer wall of the main body, the present invention provides multiple accommodating grooves in the wall surface of the main body, and at least a portion of the air fryer assembly is provided in the accommodating grooves, thereby reducing the height to which the air fryer assembly protrudes from the wall surface of the main body. In some embodiments, the wall surface of the main body is provided with multiple accommodating grooves, and at least a portion of the accommodating grooves are recessed toward the cooking chamber. That is, the groove walls of the accommodating grooves extend into the cooking chamber, and at least a portion of the air fryer assembly is located in the accommodating grooves that are recessed toward the cooking chamber. As a result, the height to which the air fryer assembly protrudes from the main body wall can be reduced by occupying a portion of the space in the cooking chamber, shortening the distance between the cooking appliance housing and the cooking box wall, narrowing the frame width of the cooking appliance, and reducing the volume of the cooking appliance. Cooking appliances employing the cooking box according to this application can have their frame width reduced to 30 mm.

[0010] Furthermore, each component of the air fryer assembly employs a nested structure design, thereby reducing the overall height of the air fryer assembly. This nested design allows for a reduction in the air fryer assembly height to 50mm, further reducing the volume of the cooking appliance that utilizes a cooking box.

[0011] The main body wall is provided with a recessed housing groove that faces toward the cooking chamber, and by mounting at least a portion of the air fryer assembly within the housing groove, the height to which the air fryer assembly protrudes from the main body wall can be reduced. This shortens the distance between the cooking appliance housing and the cooking box wall, narrows the width of the cooking appliance frame, reduces the volume of the cooking appliance, makes the structure of the cooking appliance more compact, and is advantageous for miniaturizing the product design.

[0012] The cooking box according to the present invention may have the following distinguishing technical features.

[0013] In the above proposed technology, the air fryer assembly further includes a fan assembly for forming an airflow and a heating assembly for forming hot air by heating the airflow formed by the fan assembly. The body includes a first top plate, which constitutes the ceiling of the cooking chamber, and a plurality of accommodating grooves, which include a first accommodating groove and a second accommodating groove, the first accommodating groove being recessed toward the cooking chamber and the second accommodating groove protruding toward away from the cooking chamber, at least a portion of the fan assembly is located in the first accommodating groove and at least a portion of the heating assembly is located in the second accommodating groove.

[0014] This proposed technology defines the structure of an air fryer assembly. The air fryer assembly includes a fan assembly and a heating assembly, wherein the fan assembly is used to form an airflow, and the heating assembly is capable of generating heat, and when the heating assembly is in operation, it heats the airflow formed by the fan assembly to form hot air, and the fan assembly can blow the hot air heated and formed by the heating assembly into the cooking chamber, thereby air frying the food in the cooking chamber.

[0015] In a possible technical proposal, the heating assembly is a heating tube, and the heating assembly is located on the side of the fan assembly facing the cooking chamber, thereby heating the airflow formed by the fan assembly via the heating assembly.

[0016] Furthermore, in order to reduce the height to which the air fryer assembly protrudes from the wall surface of the main body, the present invention provides a first top plate having a plurality of accommodating grooves in the main body, and installs at least a portion of the air fryer assembly within the accommodating grooves, thereby reducing the height to which the air fryer assembly protrudes from the wall surface of the main body. In some embodiments, the main body includes a first top plate, which constitutes the ceiling of the cooking chamber, and the plurality of accommodating grooves include a first accommodating groove and a second accommodating groove, both of which are provided in the first top plate, where the first accommodating groove is recessed toward the cooking chamber, and the second accommodating groove protrudes toward the direction away from the cooking chamber, that is, the groove opening of the first accommodating groove opens toward the outside, and the groove opening of the second accommodating groove opens toward the inside of the cooking chamber. The air fryer assembly is provided at the top of the main body, and the air fryer assembly includes a fan assembly and a heating assembly, where at least a portion of the fan assembly is located within the first accommodating groove, and at least a portion of the heating assembly is located within the second accommodating groove. In this way, the height to which the fan assembly protrudes from the first top plate is reduced, achieving the technical effect of narrowing the edges of the cookware, while also reducing the space occupied by the heating assembly in the cooking chamber. Furthermore, because the opening of the second housing groove faces inward into the cooking chamber, more heat generated by the heating assembly is released into the cooking chamber, improving heating efficiency.

[0017] Furthermore, the first top plate includes an opening that communicates with the cooking chamber. When the air fryer assembly is in operation, the fan assembly forms an airflow, which is blown into the cooking chamber through the opening in the first top plate. The heating assembly generates heat, heating the airflow formed by the fan assembly to create hot air. In this way, the hot air heats the food in the cooking chamber, achieving the cooking effect of the air fryer.

[0018] The first top plate is provided with a first housing groove that is recessed toward the cooking chamber and a second housing groove that protrudes toward the cooking chamber. At least a portion of the fan assembly is mounted in the first housing groove, and the heating assembly is mounted in the second housing groove. This reduces the height to which the fan assembly protrudes from the first top plate, achieving the technical effect of narrowing the edges of the cooking appliance, while also reducing the space occupied by the heating assembly in the cooking chamber, thereby improving the space utilization rate of the cooking chamber.

[0019] In the above proposed technology, the fan assembly further includes a drive motor and a plurality of blades connected to the drive motor, the drive motor being used to rotate the plurality of blades to form an airflow. The body further includes a second top plate, the second top plate located on the side of the first top plate away from the cooking chamber, the second top plate having a third housing groove, the third housing groove being recessed toward the cooking chamber, at least a portion of the drive motor located in the third housing groove, and at least a portion of the blades located in the first housing groove.

[0020] This proposed technology limits the structure of the fan assembly. The fan assembly includes a drive motor and multiple blades, the multiple blades being connected to the drive motor. When the fan assembly is operating, the drive motor rotates the multiple blades to form an airflow. The multiple blades are positioned on the side of the drive motor facing the cooking chamber.

[0021] Furthermore, in order to reduce the height to which the fan assembly protrudes from the wall surface of the main body, the present invention further provides the main body with a second top plate including a third housing groove, thereby reducing the height to which the fan assembly protrudes from the wall surface of the main body. In some embodiments, the second top plate is located on the side of the first top plate away from the cooking chamber, and the second top plate is provided with a third housing groove, the third housing groove is recessed toward the cooking chamber, at least a portion of the drive motor is located in the third housing groove, and at least a portion of the blades is located in the first housing groove. In this way, the height to which the fan assembly protrudes from the wall surface of the main body is reduced, achieving the technical effect of narrowing the edge of the cooking appliance, while at the same time, since the drive motor and the cooking chamber are separated by the second top plate, the effect of high temperatures in the cooking chamber on the drive motor is reduced, and the life of the drive motor can be extended.

[0022] The main body is provided with a second top plate, and the drive motor is mounted in a third recessed housing groove within the cooking chamber. This reduces the height at which the drive motor protrudes from the wall of the main body, and also reduces the height at which the fan assembly protrudes from the wall of the main body, making it easier to achieve the technical benefit of narrowing the edges of the cooking appliance.

[0023] In the above proposed technology, the cooking box further includes an exhaust plate provided on the side of the fan assembly facing the cooking chamber, the exhaust plate having a plurality of exhaust ports, which are used to blow the airflow formed by the fan assembly into the cooking chamber.

[0024] This invention further limits the structure of the cooking box. In order to ensure that hot air is uniformly blown into the cooking chamber, the cooking box is further provided with an exhaust plate. The exhaust plate is located on the side of the fan assembly facing the cooking chamber, and is provided with multiple exhaust ports, through which the hot air can be blown into the cooking chamber. Since the multiple exhaust ports are evenly distributed on the exhaust plate, the direction of the hot air flow can be adjusted by the evenly distributed multiple exhaust ports, and the hot air can be uniformly blown into the cooking chamber.

[0025] Furthermore, a certain interval is provided between the exhaust plate and the first top plate. Thus, the hot air first flows between the first top plate and the exhaust plate, sufficiently flows to the positions where the plurality of exhaust ports are located, and then is blown into the cooking chamber through the plurality of exhaust ports, and is blown into the cooking chamber more uniformly.

[0026] An exhaust plate is provided on the side of the fan assembly facing the cooking chamber, and a plurality of exhaust ports are provided on the exhaust plate. Thereby, hot air is blown into the cooking chamber through the plurality of exhaust ports, and the hot air is blown into the cooking chamber uniformly, heating the food materials uniformly, and improving the cooking effect.

[0027] In the above technical solution, furthermore, the cooking box further includes a microwave assembly. The microwave assembly is located on the side away from the air fryer assembly of the main body. On the side of the microwave assembly facing the cooking chamber, a plurality of introduction ports are provided, and the microwave assembly radiates microwaves into the cooking chamber through the introduction ports.

[0028] In this technical solution, the structure of the cooking box is further limited. In order to endow the cooking appliance with a plurality of cooking modes and meet the diverse needs of users, in the present application, the cooking box is further provided with a microwave assembly, and the microwave assembly can perform microwave heating on the food materials in the cooking chamber. The microwave assembly and the air fryer assembly can each operate independently or operate simultaneously, thereby endowing the cooking appliance with a plurality of cooking modes, meeting different needs of users, and enhancing the convenience in use.

[0029] Furthermore, by being provided on a side away from the air fryer assembly of the main body, when the microwave assembly and the air fryer assembly operate simultaneously, both sides of the food can be heated simultaneously, improving the cooking effect. And by being provided on a side away from the air fryer assembly of the main body, the structure of the cooking box can be made more compact, which is advantageous for the miniaturization design of the product. In a possible technical solution, the microwave assembly is provided at the bottom of the main body, and the air fryer assembly is provided at the top of the main body.

[0030] Furthermore, the structure of the microwave assembly is limited. On the side facing the cooking chamber of the microwave assembly, a plurality of introduction ports are provided, and the microwave assembly can radiate microwaves into the cooking chamber through the plurality of introduction ports. Compared with the structure of transmitting microwaves into the cooking chamber using a conventional stirring member, in the present application, by radiating microwaves into the cooking chamber through the plurality of introduction ports, while uniformly radiating microwaves into the cooking chamber, the space occupied by the microwave assembly is reduced, thereby reducing the volume of the cooking box, making the structure of the cooking box more compact, which is advantageous for the miniaturization design of the product. The plurality of introduction ports each radiate microwaves into the cooking chamber, and the microwaves radiated from the plurality of introduction ports overlap, so that the distribution of the microwave field in each region of the cooking chamber is made uniform, and the food can be heated uniformly. The bottom wall of the cooking chamber is composed of glass that can transmit microwaves, so that the introduction ports are configured to radiate microwaves into the cooking chamber through the bottom wall of the cooking chamber.

[0031] By equipping the cooking box with a microwave assembly, the cooking appliance can be given a microwave heating cooking mode, meeting the diverse cooking needs of users and improving user convenience. The microwave assembly is provided with multiple input ports, and by radiating microwaves into the cooking chamber through these multiple input ports, the microwaves radiated from the multiple input ports overlap, resulting in a uniform distribution of the microwave field in each area of ​​the cooking chamber, allowing for uniform heating of food. At the same time, a stirring device is not required, reducing the space occupied by the microwave assembly, thereby reducing the volume of the cooking box, making the cooking box structure more compact, and advantageous for miniaturization of the product design.

[0032] In the above proposed technology, the microwave assembly further includes a microwave generator for generating microwaves and a plurality of waveguides surrounding a waveguide chamber, the microwave generator communicating with the waveguide chamber and a plurality of introduction ports provided in the ceiling of the waveguide chamber.

[0033] This proposed technology limits the structure of the microwave assembly. The microwave assembly includes a microwave generator for generating microwaves and a plurality of waveguides surrounding a waveguide chamber for conducting microwaves. In some embodiments, the waveguide chamber communicates with the microwave generator, and the microwaves generated by the microwave generator first enter the waveguide chamber and propagate through the waveguide chamber toward the cooking chamber. A plurality of introduction ports are provided in the ceiling of the waveguide chamber, and the microwaves are introduced into the cooking chamber through the plurality of introduction ports to realize microwave propagation.

[0034] By providing a microwave generator and multiple waveguides in the microwave assembly, microwaves generated by the microwave generator enter the cooking chamber through a waveguide chamber surrounded by the multiple waveguides, thereby enabling microwave propagation.

[0035] In some technical proposals, for example, the cooking box further includes a waveguide port located in the bottom wall of the waveguide chamber and used to connect the waveguide chamber with a microwave generator.

[0036] This proposed technology further limits the structure of the cooking box. In order to allow microwaves generated by the microwave generator to enter the waveguide chamber, the present invention further provides a waveguide opening in the bottom wall of the waveguide chamber, which connects the microwave generator and the waveguide chamber, allowing microwaves generated by the microwave generator to enter the waveguide chamber through the waveguide opening, thereby enabling microwave propagation.

[0037] A waveguide port is provided in the bottom wall of the waveguide chamber, which communicates with the microwave generator. This allows microwaves generated by the microwave generator to enter the waveguide chamber through the waveguide port, thereby enabling microwave propagation.

[0038] In some technical proposals, for example, the air fryer assembly is located at the top of the main body, and the microwave assembly is located at the bottom of the main body.

[0039] This proposed technology limits the installation locations of the air fryer assembly and microwave assembly. In some embodiments, the air fryer assembly is located at the top of the main body, and the microwave assembly is located at the bottom of the main body. This allows the microwave generator and air fryer assembly to heat both sides of the food, ensuring uniform heating and improving the cooking effect. Compared to structures where the air fryer assembly and microwave assembly are located on the sides of the main body, in this invention, by positioning the air fryer assembly and microwave assembly at the top and bottom of the main body, respectively, the microwave assembly and air fryer assembly occupy the same height mounting space as other components in the cooking box, eliminating the need for additional mounting space. This allows for a more compact cooking box structure and is advantageous for miniaturizing the product design.

[0040] In some technical proposals, the cooking box further includes, as an example, a cooling fan located at the bottom of the main body, and an air duct assembly connected to the cooling fan and extending along the walls of the main body to cool components within the cooking box.

[0041] This proposed technology further defines the structure of the cooking box. As can be understood, when the cooking appliance is in operation, the temperature of each component in the cooking box rises. To prevent each component from malfunctioning due to overheating, the present invention provides the cooking box with a cooling fan and an air duct assembly for cooling each component in the cooking box. Here, the cooling fan is located at the bottom of the main body, the air duct assembly is connected to the cooling fan, and the airflow formed by the fan assembly is blown into the air duct assembly and flows along the air duct assembly, cooling the components through which the air duct assembly passes. The air duct assembly extends along the wall surface of the main body, and the extension path of the air duct assembly passes through multiple components in the main body. As airflow flows through the air duct assembly, the air duct assembly removes heat from the components along its path, achieving the technical effect of cooling each component in the main body by the cooling fan and air duct assembly.

[0042] The main unit is equipped with a cooling fan and an air duct assembly. The airflow through the air duct assembly cools each component it passes through, preventing the components in the main unit from overheating, ensuring that the cooking appliance operates normally, and extending the product's lifespan.

[0043] In some technical proposals, for example, the cooking box includes an inverter located at the bottom of the main body and a control board located at the bottom of the main body for controlling the operation of the air fryer assembly and the microwave assembly, and the air duct assembly includes a first air duct connected to a cooling fan and cooling the inverter and the control board via the inverter and the control board.

[0044] The proposed technology further defines the structure of the cooking box. The cooking box includes an inverter located at the bottom of the cooking box. Cooking appliances employing the cooking box are connected to an external power source, and the inverter adjusts the voltage supplied from the power source so that the adjusted voltage meets the operating requirements of the cooking appliance.

[0045] Furthermore, the cooking box further includes a control board, which is located at the bottom of the main body and is used to control the operation of the air fryer assembly and the microwave assembly.

[0046] To make it clear that when the cooking appliance is in operation, the inverter and control board generate heat, and in order to prevent the control board and inverter from overheating, the present invention provides an air duct assembly that passes through the inverter and control board, thereby cooling the inverter and control board. In some embodiments, the air duct assembly includes a first air duct, which is connected to a cooling fan, and the airflow formed by the cooling fan enters and flows along the first air duct, which passes through the inverter and control board. This allows the inverter and control board to be cooled and reduced in temperature.

[0047] The air duct assembly is provided with a first air duct that passes through the inverter and control board. This first air duct cools the inverter and control board, lowering their temperature and preventing them from overheating, thus ensuring that the inverter and control board operate normally.

[0048] In some technical proposals, for example, the cooking box further includes a door assembly that is movably connected to the main body, and a microswitch connected to the door assembly for opening and closing the door assembly, and the air duct assembly further includes a second air duct that communicates with the first air duct and extends toward the microswitch for cooling the microswitch.

[0049] The present invention further defines the structure of the cooking box. The cooking box further includes a door assembly and a microswitch, where the door assembly is movably connected to the main body, and the microswitch is connected to the door assembly and used to open and close the door assembly, thereby opening and closing the cooking chamber. In order to cool the microswitch and ensure that the microswitch operates properly, the present invention provides a second air duct in the air duct assembly, the second air duct communicating with the first air duct, the second air duct extending toward the microswitch, and guiding airflow through the second air duct to the microswitch to cool the microswitch.

[0050] The air duct assembly is provided with a second air duct, which extends toward the microswitch. This cools the microswitch, preventing it from overheating, ensuring it operates correctly, and improving its reliability.

[0051] In some technical proposals, for example, the ratio of the cross-sectional areas of the first air duct to the second air duct is in the range of 7:3 to 9:1.

[0052] This proposed technology limits the ratio of the cross-sectional areas of the first air duct and the second air duct. In some embodiments, the ratio of the cross-sectional areas of the first air duct and the second air duct is in the range of 7:3 to 9:1. In this way, the airflow rate within the first and second air ducts can be rationally distributed, and each component can be sufficiently cooled to reduce its temperature.

[0053] In possible technical proposals, the ratio of the cross-sectional areas of the first air duct to the second air duct is in the range of 8:2.

[0054] In some technical proposals, for example, the air duct assembly further includes a third air duct communicating with the end of the first air duct away from the cooling fan and cooling the microwave assembly via the microwave assembly, and a fourth air duct communicating with the end of the first air duct away from the cooling fan and extending toward the air fryer assembly to cool the air fryer assembly.

[0055] The proposed technology further defines the structure of the air duct assembly. The air duct assembly further includes a third air duct and a fourth air duct, the third air duct communicating with the end of the first air duct away from the cooling fan, and a portion of the airflow in the first air duct flows into the third air duct. By passing through the microwave assembly via the third air duct, the airflow in the third air duct can cool the microwave assembly, preventing it from overheating. The fourth air duct communicates with the end of the first air duct away from the cooling fan, and a portion of the airflow in the first air duct flows into the fourth air duct. The fourth air duct extends toward the air fryer assembly, guiding the airflow through the fourth air duct to the air fryer assembly, thereby cooling the air fryer assembly and preventing it from overheating.

[0056] The air duct assembly is provided with a third air duct and a fourth air duct, which allows the microwave assembly and the air fryer assembly to be cooled via the third air duct and the fourth air duct, respectively. This prevents the microwave assembly and the air fryer assembly from overheating, ensures that the microwave assembly and the air fryer assembly operate normally, and improves the reliability of the microwave assembly and the air fryer assembly.

[0057] In some technical proposals, for example, the ratio of the cross-sectional areas of the third air duct to the fourth air duct is in the range of 6:4 to 8:2.

[0058] This proposed technology limits the ratio of the cross-sectional areas of the third air duct and the fourth air duct. In some embodiments, the ratio of the cross-sectional areas of the third air duct to the fourth air duct is in the range of 6:4 to 8:2. In this way, the airflow rate in the third air duct and the fourth air duct can be rationally distributed, allowing the microwave assembly and the air fryer assembly to be sufficiently cooled and de-temperatureized.

[0059] In possible technical proposals, the ratio of the cross-sectional areas of the third air duct to the fourth air duct is in the range of 7:3.

[0060] A second aspect of the present application further provides a cooking utensil including a cooking box according to the first aspect of the present application.

[Modes for carrying out the invention]

[0065] 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 are no conflicts, the embodiments and features of this application can be combined with each other.

[0066] Many specific details are provided in the following description to ensure a full understanding of the present application. However, since the present application can also be implemented in ways different from those described herein, the scope of protection is not limited to the specific embodiments disclosed below.

[0067] Hereinafter, a cooking box 100 and cooking utensils according to several embodiments of the present application will be described with reference to Figures 1 to 14.

[0068] In one embodiment of the present application, as shown in Figures 1, 2, 6, 8 and 10, a first aspect of the present application proposes a cooking box 100 comprising a main body 110 including a cooking chamber 111 and an air fryer assembly 120 for blowing hot air into the cooking chamber 111, wherein the walls of the main body 110 are provided with a plurality of accommodating grooves 140, at least a portion of which are recessed toward the cooking chamber 111, and at least a portion of which is located within the accommodating grooves 140 that are recessed toward the cooking chamber 111.

[0069] The cooking box 100 according to the present invention is applicable to cooking appliances, and the cooking box 100 includes a main body 110, the main body 110 includes a cooking chamber 111, the cooking chamber 111 is used to store food ingredients, and when the cooking appliance is in operation, the cooking appliance cooks the food ingredients in the cooking chamber 111.

[0070] Furthermore, the cooking box 100 includes an air fryer assembly 120, which can cook the food in the cooking chamber 111 in an air fryer manner. In some embodiments, when the air fryer assembly 120 is in operation, it can blow hot air into the cooking chamber 111, thereby heating the food in the cooking chamber 111 via the hot air and achieving the cooking effect of an air fryer. The air fryer assembly 120 is composed of multiple members, thereby having a certain thickness. In order to reduce the height to which the air fryer assembly 120 protrudes from the outer wall of the main body 110, the present invention provides a plurality of accommodating grooves 140 on the wall surface of the main body 110, and at least a portion of the air fryer assembly 120 is provided in the accommodating grooves 140, thereby reducing the height to which the air fryer assembly 120 protrudes from the wall surface of the main body 110. In some embodiments, the wall surface of the main body 110 is provided with a plurality of accommodating grooves 140, and at least a portion of the accommodating grooves 140 is recessed toward the cooking chamber 111, that is, the groove walls of the accommodating grooves 140 extend into the cooking chamber 111, and at least a portion of the air fryer assembly 120 is located within the accommodating grooves 140 that are recessed toward the cooking chamber 111. As a result, the height to which the air fryer assembly 120 protrudes from the wall surface of the main body 110 can be reduced by the air fryer assembly 120 occupying a portion of the space of the cooking chamber 111, thereby shortening the distance between the housing of the cooking appliance and the wall surface of the cooking box 100, narrowing the frame width of the cooking appliance, and reducing the volume of the cooking appliance. A cooking appliance employing the cooking box 100 according to the present invention can reduce the frame width to 30 mm.

[0071] Furthermore, each component of the air fryer assembly 120 employs a nested structure design, thereby reducing the height of the air fryer assembly 120. By adopting a nested structure design, the height of the air fryer assembly 120 can be reduced to 50 mm, further reducing the volume of the cooking appliance using the cooking box 100.

[0072] The wall surface of the main body 110 is provided with a recessed storage groove 140 that faces toward the cooking chamber 111, and at least a portion of the air fryer assembly 120 is mounted within the storage groove 140. This reduces the height to which the air fryer assembly 120 protrudes from the wall surface of the main body 110, thereby shortening the distance between the housing of the cooking appliance and the wall surface of the cooking box 100, narrowing the frame width of the cooking appliance, reducing the volume of the cooking appliance, making the structure of the cooking appliance more compact, and is advantageous for miniaturizing the product design.

[0073] In some embodiments, as an example, as shown in Figures 1, 2, 8, and 9, the air fryer assembly 120 includes a fan assembly 121 for forming an airflow and a heating assembly 122 for forming hot air by heating the airflow formed by the fan assembly 121. The body 110 includes a first top plate 112, which constitutes the ceiling of the cooking chamber 111, and a plurality of accommodating grooves 140, which include a first accommodating groove 141 and a second accommodating groove 142, which are provided in the first top plate 112, with the first accommodating groove 141 recessed toward the cooking chamber 111 and the second accommodating groove 142 protruding toward away from the cooking chamber 111, with at least a portion of the fan assembly 121 located in the first accommodating groove 141 and at least a portion of the heating assembly 122 located in the second accommodating groove 142.

[0074] In this embodiment, the structure of the air fryer assembly 120 is limited. The air fryer assembly 120 includes a fan assembly 121 and a heating assembly 122, the fan assembly 121 being used to form an airflow. The heating assembly 122 is capable of generating heat, and when the heating assembly 122 is in operation, it heats the airflow formed by the fan assembly 121 to form hot air. The fan assembly 121 can blow the hot air heated and formed by the heating assembly 122 into the cooking chamber 111, thereby air frying the food in the cooking chamber 111.

[0075] In one possible embodiment, the heating assembly 122 is a heating tube, and the heating assembly 122 is located on the side of the fan assembly 121 facing the cooking chamber 111, thereby heating the airflow formed by the fan assembly 121 via the heating assembly 122.

[0076] Furthermore, in order to reduce the height to which the air fryer assembly 120 protrudes from the wall surface of the main body 110, the present invention provides a first top plate 112 in the main body 110 that includes a plurality of accommodating grooves 140, and installs at least a portion of the air fryer assembly 120 within the accommodating grooves 140, thereby reducing the height to which the air fryer assembly 120 protrudes from the wall surface of the main body 110.

[0077] In some embodiments, the main body 110 includes a first top plate 112, which constitutes the ceiling of the cooking chamber 111. A plurality of accommodating grooves 140 include a first accommodating groove 141 and a second accommodating groove 142, both of which are provided in the first top plate 112. The first accommodating groove 141 is recessed toward the cooking chamber 111, and the second accommodating groove 142 protrudes toward away from the cooking chamber 111. That is, the groove opening of the first accommodating groove 141 opens toward the outside, and the groove opening of the second accommodating groove 142 opens toward the inside of the cooking chamber 111. An air fryer assembly 120 is provided on top of the main body 110, and the air fryer assembly 120 includes a fan assembly 121 and a heating assembly 122. At least a portion of the fan assembly 121 is located within the first housing groove 141, and at least a portion of the heating assembly 122 is located within the second housing groove 142. In this way, the height to which the fan assembly 121 protrudes from the first top plate 112 is reduced, achieving the technical effect of narrowing the edges of the cookware, while also reducing the space occupied by the heating assembly 122 in the cooking chamber 111. Furthermore, since the opening of the second housing groove 142 faces into the cooking chamber 111, more of the heat generated by the heating assembly 122 is released into the cooking chamber 111, improving heating efficiency.

[0078] Furthermore, the first top plate 112 includes an opening that communicates with the cooking chamber 111. When the air fryer assembly 120 is in operation, the fan assembly 121 forms an airflow, which is blown into the cooking chamber 111 through the opening in the first top plate 112. The heating assembly 122 generates heat and heats the airflow formed by the fan assembly 121 to form hot air. In this way, the hot air heats the food in the cooking chamber 111, achieving the cooking effect of an air fryer.

[0079] The first top plate 112 is provided with a first accommodating groove 141 that is recessed toward the cooking chamber 111 and a second accommodating groove 142 that protrudes toward away from the cooking chamber 111. At least a portion of the fan assembly 121 is mounted in the first accommodating groove 141, and the heating assembly 122 is mounted in the second accommodating groove 142. This reduces the height to which the fan assembly 121 protrudes from the first top plate 112, achieving the technical effect of narrowing the edges of the cooking appliance, while also reducing the space occupied by the heating assembly 122 in the cooking chamber 111, thereby improving the space utilization rate of the cooking chamber 111.

[0080] In some embodiments, as an example, as shown in Figures 2 and 8, the fan assembly 121 includes a drive motor 123 and a plurality of blades 124 connected to the drive motor 123, the drive motor 123 being used to rotate the plurality of blades 124 to form an airflow. The body 110 further includes a second top plate 113, which is located on the side of the first top plate 112 away from the cooking chamber 111. The second top plate 113 is provided with a third housing groove 143, which is recessed toward the cooking chamber 111, at least a portion of the drive motor 123 is located in the third housing groove 143, and at least a portion of the blades 124 is located in the first housing groove 141.

[0081] In this embodiment, the structure of the fan assembly 121 is limited. The fan assembly 121 includes a drive motor 123 and a plurality of blades 124, the plurality of blades 124 being connected to the drive motor 123. When the fan assembly 121 is operating, the drive motor 123 rotates the plurality of blades 124 to form an airflow. Here, the plurality of blades 124 are located on the side of the drive motor 123 facing the cooking chamber 111.

[0082] Furthermore, in order to reduce the height to which the fan assembly 121 protrudes from the wall surface of the main body 110, the main body 110 is further provided with a second top plate 113 including a third housing groove 143, thereby reducing the height to which the fan assembly 121 protrudes from the wall surface of the main body 110.

[0083] In some embodiments, the second top plate 113 is located on the side of the first top plate 112 away from the cooking chamber 111, and the second top plate 113 is provided with a third housing groove 143. The third housing groove 143 is recessed toward the cooking chamber 111, and at least a portion of the drive motor 123 is located in the third housing groove 143, and at least a portion of the blades 124 is located in the first housing groove 141. In this way, the height to which the fan assembly 121 protrudes from the wall surface of the main body 110 can be reduced, achieving the technical effect of narrowing the edge of the cookware. At the same time, because the drive motor 123 and the cooking chamber 111 are separated by the second top plate 113, the effect of the high temperature inside the cooking chamber 111 on the drive motor 123 can be reduced, and the lifespan of the drive motor 123 can be extended.

[0084] The main body 110 is provided with a second top plate 113, and the drive motor 123 is mounted in a third housing groove 143 recessed within the cooking chamber 111. This reduces the height at which the drive motor 123 protrudes from the wall surface of the main body 110, and also reduces the height at which the fan assembly 121 protrudes from the wall surface of the main body 110, making it easier to achieve the technical effect of narrowing the edges of the cooking appliance.

[0085] In some embodiments, as an example, as shown in Figure 2, the cooking box 100 further includes an exhaust plate 114 provided on the side of the fan assembly 121 facing the cooking chamber 111, the exhaust plate 114 being provided with a plurality of exhaust ports 115, which are used to blow the airflow formed by the fan assembly 121 into the cooking chamber 111.

[0086] In this embodiment, the structure of the cooking box 100 is further limited. In order for hot air to be blown uniformly into the cooking chamber 111, the cooking box 100 is further provided with an exhaust plate 114 for exhaust. The exhaust plate 114 is provided on the side of the fan assembly 121 facing the cooking chamber 111, and the exhaust plate 114 is provided with a plurality of exhaust ports 115, so that hot air can be blown into the cooking chamber 111 through the plurality of exhaust ports 115. Since the plurality of exhaust ports 115 are evenly distributed on the exhaust plate 114, the direction of the hot air flow can be adjusted by the evenly distributed plurality of exhaust ports 115, so that the hot air can be blown uniformly into the cooking chamber 111.

[0087] Furthermore, a certain gap is provided between the exhaust plate 114 and the first top plate 112. In this way, the hot air first flows between the first top plate 112 and the exhaust plate 114, flows sufficiently to the location of the multiple exhaust ports 115, and is then blown into the cooking chamber 111 through the multiple exhaust ports 115, allowing it to be blown into the cooking chamber 111 more uniformly.

[0088] An exhaust plate 114 is provided on the side of the fan assembly 121 facing the cooking chamber 111, and multiple exhaust ports 115 are provided on the exhaust plate 114. As a result, hot air is blown into the cooking chamber 111 through the multiple exhaust ports 115, and the hot air is blown uniformly into the cooking chamber 111, which heats the food uniformly and improves the cooking effect.

[0089] In some embodiments, as an example, as shown in Figure 2, the cooking box 100 further includes a microwave assembly 130, which is located on the side of the main body 110 away from the air fryer assembly 120, and the side of the microwave assembly 130 facing the cooking chamber 111 is provided with a plurality of inlet ports 134, which radiate microwaves into the cooking chamber 111 through the inlet ports 134.

[0090] In this embodiment, the structure of the cooking box 100 is further limited. In order to provide the cooking appliance with multiple cooking modes and to meet the diverse needs of users, the cooking box 100 is further provided with a microwave assembly 130, which can perform microwave heating on the food in the cooking chamber 111. The microwave assembly 130 and the air fryer assembly 120 can be operated independently or simultaneously, thereby providing the cooking appliance with multiple cooking modes, meeting different user needs, and improving ease of use.

[0091] Furthermore, by positioning the microwave assembly 130 on the side of the main body 110 away from the air fryer assembly 120, both sides of the food can be heated simultaneously when the microwave assembly 130 and the air fryer assembly 120 are operating at the same time, thereby improving the cooking effect. Also, positioning the microwave assembly 130 on the side of the main body 110 away from the air fryer assembly 120 makes the structure of the cooking box 100 more compact, which is advantageous for miniaturizing the product design. In one possible embodiment, the microwave assembly 130 is located at the bottom of the main body 110, and the air fryer assembly 120 is located at the top of the main body 110.

[0092] Furthermore, the structure of the microwave assembly 130 is limited. Multiple introduction ports 134 are provided on the side of the microwave assembly 130 facing the cooking chamber 111, and the microwave assembly 130 can radiate microwaves into the cooking chamber 111 via the multiple introduction ports 134. Compared with conventional structures that transmit microwaves into the cooking chamber 111 using a stirring member, in this invention, by radiating microwaves into the cooking chamber 111 via the multiple introduction ports 134, microwaves are radiated uniformly into the cooking chamber 111 while reducing the space occupied by the microwave assembly 130, thereby reducing the volume of the cooking box 100, making the structure of the cooking box 100 more compact, which is advantageous for miniaturization design of the product. Each of the multiple introduction ports 134 radiates microwaves into the cooking chamber 111, and the microwaves radiated from the multiple introduction ports 134 overlap, so that the distribution of the microwave field in each region of the cooking chamber 111 is made uniform, and the food can be heated uniformly. The bottom wall of the cooking chamber 111 is made of glass that transmits microwaves, so that the introduction port 134 transmits microwaves through the bottom wall of the cooking chamber 111 into the cooking chamber 111.

[0093] The cooking box 100 is equipped with a microwave assembly 130, which gives the cooking appliance a microwave heating cooking mode, meeting the diverse cooking needs of users and improving user convenience. The microwave assembly 130 is provided with multiple introduction ports 134, and by radiating microwaves into the cooking chamber 111 through these multiple introduction ports 134, the microwaves radiated from the multiple introduction ports 134 overlap. As a result, the distribution of the microwave field in each area of ​​the cooking chamber 111 is made uniform, allowing food to be heated uniformly. On the other hand, a stirring device is not required, reducing the space occupied by the microwave assembly 130, thereby reducing the volume of the cooking box 100, making the structure of the cooking box 100 more compact, which is advantageous for miniaturization design of the product.

[0094] In some embodiments, as an example, as shown in Figures 2 and 12, the microwave assembly 130 includes a microwave generator 131 for generating microwaves and a plurality of waveguides 132 surrounding a waveguide chamber 133, the microwave generator 131 communicating with the waveguide chamber 133 and a plurality of introduction ports 134 provided in the ceiling of the waveguide chamber 133.

[0095] In this embodiment, the structure of the microwave assembly 130 is limited. The microwave assembly 130 includes a microwave generator 131 for generating microwaves and a plurality of waveguides 132 surrounding a waveguide chamber 133 for conducting microwaves. In some embodiments, the waveguide chamber 133 communicates with the microwave generator 131, and the microwaves generated by the microwave generator 131 first enter the waveguide chamber 133, and the microwaves propagate within the waveguide chamber 133 toward the cooking chamber 111. A plurality of introduction ports 134 are provided on the ceiling of the waveguide chamber 133, and the microwaves are introduced into the cooking chamber 111 via the plurality of introduction ports 134 to realize microwave propagation.

[0096] By providing a microwave generator 131 and a plurality of waveguides 132 in the microwave assembly 130, microwaves generated by the microwave generator 131 enter the cooking chamber 111 through a waveguide chamber 133 surrounded by the plurality of waveguides 132, thereby enabling microwave propagation.

[0097] In some embodiments, as an example, as shown in Figure 2, the cooking box 100 further includes a waveguide port 135 provided in the bottom wall of the waveguide chamber 133 and used to connect the waveguide chamber 133 with the microwave generator 131.

[0098] In this embodiment, the structure of the cooking box 100 is further limited. In this application, a waveguide port 135 is further provided in the bottom wall of the waveguide chamber 133 so that microwaves generated by the microwave generator 131 can enter the waveguide chamber 133. The waveguide port 135 connects the microwave generator 131 and the waveguide chamber 133, allowing microwaves generated by the microwave generator 131 to enter the waveguide chamber 133 through the waveguide port 135, thereby enabling microwave propagation.

[0099] A waveguide port 135 is provided in the bottom wall of the waveguide chamber 133, which communicates with the microwave generator 131. This allows microwaves generated by the microwave generator 131 to enter the waveguide chamber 133 through the waveguide port 135, thereby enabling microwave propagation.

[0100] In some embodiments, as an example, as shown in Figures 1, 2, and 8, the air fryer assembly 120 is located at the top of the main body 110, and the microwave assembly 130 is located at the bottom of the main body 110.

[0101] In this embodiment, the installation positions of the air fryer assembly 120 and the microwave assembly 130 are limited. In some embodiments, the air fryer assembly 120 is located at the top of the main body 110, and the microwave assembly 130 is located at the bottom of the main body 110. This allows the microwave generator 131 and the air fryer assembly 120 to heat both sides of the food, ensuring uniform heating and improving the cooking effect. On the other hand, compared to a structure in which the air fryer assembly 120 and the microwave assembly 130 are located on the sides of the main body 110, in this application, by providing the air fryer assembly 120 and the microwave assembly 130 at the top and bottom of the main body 110, respectively, the microwave assembly 130 and the air fryer assembly 120 occupy a mounting space of the same height as other components in the cooking box 100, eliminating the need for additional mounting space. This makes the structure of the cooking box 100 more compact and is advantageous for miniaturizing the product design.

[0102] In some embodiments, as an example, as shown in Figures 8 and 12, the cooking box 100 further includes a cooling fan located at the bottom of the main body 110 and an air duct assembly 150 connected to the cooling fan and extending along the wall surface of the main body 110 to cool the components in the cooking box 100.

[0103] In this embodiment, the structure of the cooking box 100 is further limited. As can be understood, when the cooking appliance is in operation, the temperature of each component in the cooking box 100 rises. To prevent each component from becoming unable to function properly due to overheating, the cooking box 100 is provided with a cooling fan and an air duct assembly 150 for cooling each component in the cooking box 100. Here, the cooling fan is located at the bottom of the main body 110, and the air duct assembly 150 is connected to the cooling fan, and the airflow formed by the fan assembly 121 is blown into the air duct assembly 150 and flows along the air duct assembly 150 to cool the components through which the air duct assembly 150 passes. The cooking box 100 further includes a cooling motor 182 for driving the cooling fan, which can rotate the cooling fan to form an airflow. The cooking box 100 further includes a cooling fan bracket 181 for supporting the cooling fan. The air duct assembly 150 extends along the wall surface of the main body 110, and the extension path of the air duct assembly 150 passes through multiple components of the main body 110. As airflow flows through the air duct assembly 150, the air duct assembly 150 removes heat from the components along its path, achieving the technical effect of cooling each component of the main body 110 by the cooling fan and the air duct assembly 150.

[0104] The main body 110 is equipped with a cooling fan and an air duct assembly 150. The airflow through the air duct assembly 150 cools each component it passes through, preventing the components in the main body 110 from overheating, ensuring that the cooking appliance operates normally, and extending the product's lifespan.

[0105] In some embodiments, as an example, as shown in Figures 9, 12, and 14, the cooking box 100 further includes an inverter located at the bottom of the main body 110 and a control board located at the bottom of the main body 110 for controlling the operation of the air fryer assembly 120 and the microwave assembly 130, and the air duct assembly 150 includes a first air duct 151 connected to a cooling fan and cooling the inverter and the control board via the inverter and the control board.

[0106] In this embodiment, the structure of the cooking box 100 is further limited. The cooking box 100 includes an inverter located at the bottom of the cooking box 100. Cooking appliances employing the cooking box 100 are connected to an external power source, and the inverter adjusts the voltage supplied from the power source so that the adjusted voltage meets the usage requirements of the cooking appliance.

[0107] Furthermore, the cooking box 100 further includes a control board, which is located at the bottom of the main body 110 and is used to control the operation of the air fryer assembly 120 and the microwave assembly 130. The cooking box 100 further includes a control board bracket 180 for supporting the control board, and the control board is mounted on the control board bracket 180.

[0108] To make it clear that when the cooking appliance is in operation, the inverter and control board generate heat, and in order to prevent the control board and inverter from overheating, the present invention provides an air duct assembly 150 that passes through the inverter and control board, thereby cooling the inverter and control board. In some embodiments, the air duct assembly 150 includes a first air duct 151, which is connected to a cooling fan, and the airflow formed by the cooling fan enters and flows along the first air duct 151, passing through the inverter and control board. This allows the inverter and control board to be cooled and reduced in temperature. The direction of airflow in the first air duct 151 is shown in Figure 14.

[0109] The air duct assembly 150 is provided with a first air duct 151 that passes through the inverter and control board. This allows the inverter and control board to be cooled and cooled through the first air duct 151, preventing them from overheating and ensuring that the inverter and control board operate normally.

[0110] In some embodiments, as an example, as shown in Figures 4, 5, 7, 8 and 11, the cooking box 100 further includes a door assembly 160 movably connected to the main body 110 and a microswitch 170 connected to the door assembly 160 for opening and closing the door assembly 160, and the air duct assembly 150 further includes a second air duct 152 communicating with a first air duct 151 and extending toward the microswitch 170 to cool the microswitch 170.

[0111] In this embodiment, the structure of the cooking box 100 is further limited. The cooking box 100 further includes a door assembly 160 and a microswitch 170. The door assembly 160 is movably connected to the main body 110, and the microswitch 170 is connected to the door assembly 160 and used to open and close the door assembly 160, thereby opening and closing the cooking chamber 111. In order to cool the microswitch 170 and ensure that the microswitch 170 operates correctly, the air duct assembly 150 is provided with a second air duct 152. The second air duct 152 communicates with the first air duct 151 and extends toward the microswitch 170, guiding airflow to the microswitch 170 through the second air duct 152 to cool the microswitch 170.

[0112] The air duct assembly 150 is provided with a second air duct 152, which extends toward the microswitch 170. This allows the microswitch 170 to be cooled by the second air duct 152, preventing it from overheating, ensuring it operates correctly, and improving its reliability.

[0113] In some embodiments, for example, the ratio of the cross-sectional areas of the first air duct 151 to the second air duct 152 is in the range of 7:3 to 9:1.

[0114] In this embodiment, the ratio of the cross-sectional areas of the first air duct 151 and the second air duct 152 is limited. In some embodiments, the ratio of the cross-sectional areas of the first air duct 151 and the second air duct 152 is in the range of 7:3 to 9:1. In this way, the airflow rate in the first air duct 151 and the second air duct 152 can be rationally distributed, and each component can be sufficiently cooled to reduce its temperature.

[0115] In one possible embodiment, the ratio of the cross-sectional areas of the first air duct 151 to the second air duct 152 is in the range of 8:2.

[0116] In some embodiments, as an example, as shown in Figures 3 and 14, the air duct assembly 150 further includes a third air duct communicating with the end of the first air duct 151 away from the cooling fan and cooling the microwave assembly 130 via the microwave assembly 130, and a fourth air duct 153 communicating with the end of the first air duct 151 away from the cooling fan and extending toward the air fryer assembly 120 to cool the air fryer assembly 120.

[0117] In this embodiment, the structure of the air duct assembly 150 is further limited. The air duct assembly 150 further includes a third air duct and a fourth air duct 153. Here, the third air duct communicates with the end of the first air duct 151 away from the cooling fan, and a portion of the airflow in the first air duct 151 flows into the third air duct. By passing through the microwave assembly 130 via the third air duct, the airflow in the third air duct can cool the microwave assembly 130, preventing the microwave assembly 130 from overheating. The direction of airflow in the third air duct is shown in Figure 14. The fourth air duct 153 communicates with the end of the first air duct 151 away from the cooling fan, and a portion of the airflow in the first air duct 151 flows into the fourth air duct 153. The fourth air duct 153 extends toward the air fryer assembly 120, guiding the airflow through the fourth air duct 153 to the air fryer assembly 120, thereby cooling the air fryer assembly 120 and preventing it from overheating.

[0118] The air duct assembly 150 is provided with a third air duct and a fourth air duct 153, which allow the microwave assembly 130 and the air fryer assembly 120 to be cooled via the third air duct and the fourth air duct 153, respectively. This prevents the microwave assembly 130 and the air fryer assembly 120 from overheating, ensures that the microwave assembly 130 and the air fryer assembly 120 operate normally, and improves the reliability of the microwave assembly 130 and the air fryer assembly 120.

[0119] In some embodiments, for example, the ratio of the cross-sectional areas of the third air duct and the fourth air duct 153 is in the range of 6:4 to 8:2.

[0120] In this embodiment, the ratio of the cross-sectional areas of the third air duct and the fourth air duct 153 is limited. In some embodiments, the ratio of the cross-sectional areas of the third air duct and the fourth air duct 153 is in the range of 6:4 to 8:2. In this way, the airflow rate in the third air duct and the fourth air duct 153 can be rationally distributed, and the microwave assembly 130 and the air fryer assembly 120 can be sufficiently cooled and cooled.

[0121] In one possible embodiment, the ratio of the cross-sectional areas of the third air duct to the fourth air duct 153 is in the range of 7:3.

[0122] In one possible embodiment, the air fryer assembly 120 is mounted on top of the main body 110, and the entire air fryer assembly 120 has a total height of 50 mm due to its nested structure design, and the top of the main body 110 is provided with a tensile molded section (i.e., a housing groove 140) for housing the air fryer assembly 120, thereby keeping the frame width of the cooking appliance product to 30 mm or less and achieving a narrow-edge design. At the same time, the main body 110 is provided with an exhaust plate 114, and the exhaust plate 114 is provided with a mesh-like opening (i.e., an exhaust port 115), so that the air heated by the air fryer assembly 120 is agitated by the blades 124 and enters the cooking chamber 111 through the mesh-like opening to achieve the cooking effect.

[0123] In the above embodiment, a microwave system (i.e., microwave assembly 130) is mounted at the bottom of the main body 110. A magnetron (i.e., microwave generator 131) is fixed to a waveguide assembly 136, which is located at the center of the bottom of the main body 110 and enables microwave excitation. As a result, microwaves diffuse from the waveguide assembly 136 through the waveguide port 135 to the waveguide chamber 133, and from the waveguide chamber 133, the microwaves enter the cooking chamber 111 through multiple introduction ports 134, achieving uniform microwave field intensity. This microwave system has a simple design and structure, occupies little space, is easy to manufacture, and is low cost. The effect of microwave heating of food by the microwave system is as shown in Figure 13, and when microwave heating is performed on food using the microwave system, the food can be uniformly heated to 83.8°C.

[0124] In the above embodiment, the air fryer assembly 120 and magnetron generate a large amount of heat during operation. To ensure product safety, it is necessary to actively and efficiently dissipate heat from the cooking box 100. In the above embodiment, the cooling fan bracket 181 and the control board bracket 180 are combined to form an electrical equipment storage module, enabling quick assembly and replacement. At the same time, the cooling fan bracket 181 and the control board bracket 180 form a sealed air duct, and the cooling motor 182 drives a cooling fan in the sealed space to generate airflow. The airflow flows through the second air duct 152, and by adjusting the position and shape of the air duct opening, the airflow ratio of the second air duct 152 is set to 20%, cooling the microswitch 170 and ensuring the normal operation of the door assembly 160.
