Cooking cabinet and cooking utensils

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on June 30, 2023, with application number "202310795422.1" and application name "Cooking Box and Cooking Utensil", the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of household electrical appliances, and in particular to a cooking box and a cooking utensil. Background Art

[0003] In the prior art cooking appliances with air frying functions, the air frying components often occupy a large installation space, resulting in a large volume of the cooking appliance and a non-compact product structure.

[0004] Summary of the Invention

[0005] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, the first object of the present application is to propose a cooking box.

[0007] The second object of the present application is to provide a cooking appliance.

[0008] To achieve at least one of the above-mentioned purposes, according to the first aspect of the present application, a cooking box is proposed, comprising: a main body including a cooking cavity; an air frying component for blowing hot air into the cooking cavity, the wall surface of the main body having a plurality of receiving grooves, at least some of the receiving grooves being recessed in the direction toward the cooking cavity, and at least some of the air frying components being located in the receiving grooves recessed in the direction toward the cooking cavity.

[0009] The cooking box proposed in the present application can be used in a cooking appliance. The cooking box includes a main body, which includes a cooking cavity. The cooking cavity is used to accommodate food. When the cooking appliance is running, the cooking appliance cooks the food in the cooking cavity.

[0010] Furthermore, the cooking box includes an air frying assembly that can air-fry the food in the cooking cavity. In some embodiments, when the air frying assembly is in operation, the air frying assembly can blow hot air into the cooking cavity. In this way, the hot air can heat the food in the cooking cavity to achieve an air-frying cooking effect. The air frying assembly is composed of multiple components, resulting in a certain thickness. To reduce the height of the air frying assembly protruding from the outer wall of the main body, the present application provides multiple receiving grooves on the wall surface of the main body. By arranging at least part of the air frying assembly in the receiving grooves, the height of the air frying assembly protruding from the wall surface of the main body can be reduced. In some embodiments, the wall surface of the main body has multiple receiving grooves, at least some of which are recessed in the direction toward the cooking cavity, that is, the groove wall of the receiving groove extends into the cooking cavity, and at least part of the air frying assembly is located in the recessed receiving groove in the direction toward the cooking cavity. In this way, the air fryer assembly can occupy a portion of the cooking cavity space, thereby reducing the height of the air fryer assembly protruding from the wall of the main body. This reduces the distance between the outer shell of the cooking appliance and the wall of the cooking chamber, resulting in a narrower frame and a smaller size. The cooking chamber body of the present application can be used in a cooking appliance with a frame narrowed to 30 mm.

[0011] Furthermore, the various components in the air fryer assembly adopt a nested design, which can reduce the height of the air fryer assembly. By adopting a nested design structure, the height of the air fryer assembly can be reduced to 50 mm, further reducing the volume of the cooking utensil used in the cooking box.

[0012] By providing a receiving groove recessed toward the cooking cavity on the wall surface of the main body and installing at least a portion of the air frying assembly in the receiving groove, the height of the air frying assembly protruding from the wall surface of the main body can be reduced, thereby reducing the distance between the outer shell of the cooking utensil and the wall surface of the cooking box, so that the cooking utensil has a narrower frame, reduces the volume of the cooking utensil, makes the structure of the cooking utensil more compact, and is conducive to the miniaturization design of the product.

[0013] The cooking box according to the present application may also have the following distinguishing technical features:

[0014] In the above technical solution, further, the air frying component includes: a fan component for forming an airflow; a heating component, which can heat the airflow formed by the fan component to form hot air; the main body includes: a first top plate, the first top plate constitutes the top wall of the cooking cavity, and the multiple receiving grooves include a first receiving groove and a second receiving groove, the first receiving groove and the second receiving groove are arranged on the first top plate, the first receiving groove is recessed in the direction toward the cooking cavity, and the second receiving groove is convex in the direction away from the cooking cavity, at least part of the fan component is located in the first receiving groove, and at least part of the heating component is located in the second receiving groove.

[0015] This technical solution defines the structure of an air frying assembly. The air frying assembly includes a fan assembly for generating airflow and a heating assembly capable of generating heat. When the heating assembly is in operation, the heating assembly heats the airflow generated by the fan assembly to generate hot air. The fan assembly then blows the heated air generated by the heating assembly into a cooking chamber to air-fry the food in the cooking chamber.

[0016] In a possible technical solution, the heating component is a heating tube, and the heating component is located on a side of the fan component facing the cooking cavity, so that the airflow formed by the fan component can be heated by the heating component.

[0017] Furthermore, to reduce the height of the air fryer assembly protruding from the main body wall, the present application provides a first top plate having a plurality of receiving slots in the main body. At least a portion of the air fryer assembly is installed in the receiving slots, thereby reducing the height of the air fryer assembly protruding from the main body wall. In some embodiments, the main body includes a first top plate, which forms the top wall of the cooking cavity. The plurality of receiving slots include a first receiving slot and a second receiving slot, both of which are provided on the first top plate. The first receiving slot is recessed toward the cooking cavity, while the second receiving slot is raised away from the cooking cavity. That is, the notch of the first receiving slot faces the outside, while the notch of the second receiving slot faces the inside of the cooking cavity. The air frying assembly is arranged at the top of the main body, and the air frying assembly includes a fan assembly and a heating assembly, wherein at least part of the fan assembly is located in the first accommodating groove, and at least part of the heating assembly is located in the second accommodating groove. In this way, on the one hand, the height of the fan assembly protruding from the first top plate can be reduced, thereby achieving the technical effect of a narrow side of the cooking utensil. On the other hand, the space of the cooking cavity occupied by the heating assembly can be reduced. Moreover, since the opening of the second accommodating groove faces the cooking cavity, the heat generated by the heating assembly can be dissipated more into the cooking cavity, thereby improving the heating efficiency.

[0018] Furthermore, the first top plate has an opening connected to the cooking cavity. When the air frying component is running, the fan component forms an airflow, and the airflow blows toward the cooking cavity through the opening of the first top plate. The heating component generates heat to heat the airflow formed by the fan component to form hot air. In this way, the food in the cooking cavity can be heated by the hot air to achieve the air frying cooking effect.

[0019] By providing a first accommodating groove that is recessed in the direction toward the cooking cavity and a second accommodating groove that is protruding in the direction away from the cooking cavity in the first top plate, and installing at least part of the fan assembly in the first accommodating groove, and installing the heating assembly in the second accommodating groove, on the one hand, the height of the fan assembly protruding from the first top plate can be reduced, thereby achieving the technical effect of a narrow side of the cooking appliance, and on the other hand, the space in the cooking cavity occupied by the heating assembly can be reduced, thereby improving the space utilization rate of the cooking cavity.

[0020] In the above technical solution, the fan assembly further includes: a drive motor; and a plurality of fan blades connected to the drive motor, the drive motor being configured to drive the plurality of fan blades to rotate and generate airflow. The main body further includes: a second top plate, the second top plate being located on a side of the first top plate facing away from the cooking cavity, the second top plate being provided with a third receiving groove, the third receiving groove being recessed toward the cooking cavity, at least a portion of the drive motor being located within the third receiving groove, and at least a portion of the fan blades being located within the first receiving groove.

[0021] This technical solution defines the structure of the fan assembly. The fan assembly includes a drive motor and multiple blades connected to the drive motor. When the fan assembly is in operation, the drive motor drives the multiple blades to rotate, creating airflow. The multiple blades are located on the side of the drive motor facing the cooking chamber.

[0022] Furthermore, to reduce the height of the fan assembly protruding from the main body wall, the present application further provides a second top plate having a third receiving slot in the main body to reduce the height of the fan assembly protruding from the main body wall. In some embodiments, the second top plate is located on the side of the first top plate facing away from the cooking cavity. The second top plate is provided with a third receiving slot, which is recessed toward the cooking cavity. At least a portion of the drive motor is located within the third receiving slot, and at least a portion of the fan blades are located within the first receiving slot. This reduces the height of the fan assembly protruding from the main body wall, thereby achieving the technical effect of a narrow edge of the cooking appliance. Furthermore, the second top plate can separate the drive motor from the cooking cavity, reducing the impact of the high temperature within the cooking cavity on the drive motor and extending the service life of the drive motor.

[0023] By setting a second top plate in the main body and installing the drive motor in a third accommodating groove recessed toward the cooking cavity, the height of the drive motor protruding from the main body wall can be reduced, thereby reducing the height of the fan assembly protruding from the main body wall, which is conducive to achieving the technical effect of a narrow side of the cooking utensil.

[0024] In the above technical solution, the cooking box further includes: an exhaust plate, which is arranged on the side of the fan assembly facing the cooking cavity, and the exhaust plate is provided with multiple exhaust ports, which are used to discharge the airflow formed by the fan assembly into the cooking cavity.

[0025] This technical solution further defines the structure of the cooking chamber. To ensure that hot air is evenly discharged into the cooking cavity, the present application further provides an exhaust plate within the cooking chamber. The exhaust plate is located on the side of the fan assembly facing the cooking cavity and has multiple exhaust ports, through which hot air is discharged into the cooking cavity. The multiple exhaust ports are evenly distributed on the exhaust plate. This allows the hot air's flow direction to be adjusted, ensuring even discharge into the cooking cavity.

[0026] Furthermore, there is a certain distance between the exhaust plate and the first top plate, so that the hot air can first flow between the first top plate and the exhaust plate, so that the hot air can fully flow to the locations of multiple exhaust ports, and then be discharged into the cooking cavity through multiple exhaust ports, so that the hot air can be blown into the cooking cavity more evenly.

[0027] By arranging an exhaust plate on the side of the fan assembly facing the cooking cavity and arranging multiple exhaust ports on the exhaust plate, hot air can be discharged into the cooking cavity through the multiple exhaust ports, so that the hot air can be evenly discharged into the cooking cavity, so that the ingredients can be evenly heated and the cooking effect is improved.

[0028] In the above technical solution, the cooking box further includes: a microwave component, which is located on the side of the main body away from the air frying component, and a plurality of feed ports are provided on the side of the microwave component facing the cooking cavity, through which the microwave component radiates microwaves into the cooking cavity.

[0029] In this technical solution, the structure of the cooking chamber is further defined. To enable the cooking appliance to have multiple cooking modes and meet the diverse needs of users, the present application also provides a microwave component in the cooking chamber. The microwave component is capable of heating the ingredients in the cooking cavity with microwaves. The microwave component and the air frying component can operate independently or simultaneously. In this way, the cooking appliance can have multiple cooking modes to meet the different needs of users and improve user convenience.

[0030] Furthermore, the microwave assembly is located on the side of the main body facing away from the air fryer. This allows the microwave and air fryer components to heat both sides of the food simultaneously, improving the cooking effect. Furthermore, by placing the microwave assembly on the side of the main body facing away from the air fryer, the cooking chamber structure becomes more compact, facilitating a smaller product design. In one possible solution, the microwave assembly is located at the bottom of the main body, while the air fryer is located at the top.

[0031] Furthermore, the structure of the microwave assembly is defined. Multiple feed ports are provided on the side of the microwave assembly facing the cooking cavity. The microwave assembly can radiate microwaves into the cooking cavity through the multiple feed ports. Compared to conventional structures that transmit microwaves into the cooking cavity through a stirring member, the present application radiates microwaves into the cooking cavity through multiple feed ports. While achieving uniform microwave radiation into the cooking cavity, this reduces the space occupied by the microwave assembly, thereby reducing the volume of the cooking box, making the cooking box structure more compact and facilitating the miniaturization of the product. The multiple feed ports radiate microwaves into the cooking cavity separately, and the microwaves radiated by the multiple feed ports overlap to balance the microwave field areas in each area of ​​the cooking cavity, allowing the food to be evenly heated. The bottom wall of the cooking cavity is made of microwave-permeable glass, allowing the feed ports to radiate microwaves through the bottom wall of the cooking cavity into the cooking cavity.

[0032] By incorporating a microwave assembly into the cooking chamber, the cooker can be equipped with microwave heating modes to meet a user's diverse cooking needs and enhance user convenience. By providing multiple feed ports within the microwave assembly and radiating microwaves into the cooking cavity through these ports, the microwaves radiated from these multiple feed ports can be superimposed, resulting in a balanced microwave field across the cooking cavity and uniform heating of the food. Furthermore, this reduces the need for a stirring device, reducing the space occupied by the microwave assembly, and ultimately reducing the volume of the cooking chamber, making the structure more compact and facilitating miniaturization of the product.

[0033] In the above technical solution, further, the microwave component includes: a microwave generating device, which is used to generate microwaves; a plurality of waveguide plates, which together form a waveguide cavity, the microwave generating device is connected to the waveguide cavity, and a plurality of feed ports are arranged on the top wall of the waveguide cavity.

[0034] This technical solution defines the structure of a microwave assembly. The microwave assembly includes a microwave generator and multiple waveguide plates. The microwave generator generates microwaves, and the multiple waveguide plates form a waveguide cavity, which conducts the microwaves. In some embodiments, the waveguide cavity communicates with the microwave generator. Microwaves generated by the microwave generator first enter the waveguide cavity, where they propagate toward the cooking cavity. Multiple feed ports are provided on the top wall of the waveguide cavity, through which the microwaves are fed into the cooking cavity to achieve microwave propagation.

[0035] By arranging a microwave generating device and a plurality of waveguide plates in the microwave assembly, the microwaves generated by the microwave generating device can be transmitted into the cooking cavity through the waveguide cavity enclosed by the plurality of waveguide plates, thereby realizing the propagation of microwaves.

[0036] In some technical solutions, exemplarily, the cooking box further includes: a waveguide port, which is provided on the bottom wall of the waveguide cavity, and the waveguide port is used to connect the waveguide cavity and the microwave generating device.

[0037] This technical solution further defines the structure of the cooking chamber. To allow microwaves generated by the microwave generator to be transmitted into the waveguide cavity, a waveguide port is provided on the bottom wall of the waveguide cavity. The waveguide port connects the microwave generator to the waveguide cavity, allowing microwaves generated by the microwave generator to be transmitted into the waveguide cavity through the waveguide port, thereby achieving microwave propagation.

[0038] By arranging a waveguide port connected to the microwave generating device on the bottom wall of the waveguide cavity, the microwaves generated by the microwave generating device can be transmitted into the waveguide cavity through the waveguide port to realize the propagation of the microwaves.

[0039] In some technical solutions, illustratively, the air fryer component is located at the top of the main body, and the microwave component is located at the bottom of the main body.

[0040] In this technical solution, the positions of the air frying component and the microwave component are defined. In some embodiments, the air frying component is located at the top of the main body, and the microwave component is located at the bottom of the main body. In this way, on the one hand, the microwave generator and the air frying component can heat both sides of the food respectively, so that the food is heated evenly and the cooking effect is improved; on the other hand, compared with the structure in which the air frying component and the microwave component are arranged on the side of the main body, the present application arranges the air frying component and the microwave component at the top and bottom of the main body respectively, so that the microwave component and the air frying component can occupy the same height installation space as other components in the cooking box, without occupying additional installation space, thereby making the structure of the cooking box more compact and conducive to the miniaturization design of the product.

[0041] In some technical solutions, exemplarily, the cooking box further includes: a cooling fan, disposed at the bottom of the main body; and an air duct assembly connected to the cooling fan, the air duct assembly extending along the wall of the main body to dissipate heat from components in the cooking box.

[0042] In this technical solution, the structure of the cooking chamber is further defined. It is understood that when the cooking appliance is in operation, the temperature of the various components within the cooking chamber rises. To prevent these components from malfunctioning due to overheating, the present application provides a cooling fan and duct assembly within the cooking chamber for dissipating heat from the various components within the cooking chamber. The cooling fan is located at the bottom of the main body, and the duct assembly is connected to the cooling fan. Airflow generated by the fan assembly is blown into the duct assembly and flows along the duct assembly to dissipate heat from the components through which the duct assembly passes. The duct assembly extends along the wall of the main body, and its extension path passes through multiple components within the main body. Due to the airflow within the duct assembly, the duct assembly can remove heat from the components through which it passes, thereby achieving the technical effect of dissipating heat from the various components within the main body through the cooling fan and duct assembly.

[0043] By setting a cooling fan and an air duct assembly in the main body, the airflow flowing in the air duct assembly can dissipate heat from the various components through which the air duct assembly passes, preventing the components in the main body from overheating, ensuring that the cooking appliance can operate normally, and extending the service life of the product.

[0044] In some technical solutions, exemplarily, the cooking box also includes: an inverter, which is located at the bottom of the main body; a control panel, which is located at the bottom of the main body, and the control panel is used to control the operation of the air frying component and the microwave component; the air duct component includes: a first air duct, the first air duct is connected to the cooling fan, and the first air duct passes through the inverter and the control panel to dissipate heat from the inverter and the control panel.

[0045] This technical solution further defines the structure of the cooking box. The cooking box includes an inverter located at the bottom of the cooking box. The cooking appliance used in the cooking box is connected to an external power source. The inverter regulates the voltage supplied by the power source to meet the cooking appliance's operating requirements.

[0046] Furthermore, the cooking box also includes a control panel, which is arranged at the bottom of the main body and is used to control the operation of the air frying component and the microwave component.

[0047] Understandably, when the cooking appliance is operating, the inverter and control board generate heat. To prevent overheating of the wall-mounted control board and inverter, the present application provides an air duct assembly that passes through the inverter and control board to cool them. In some embodiments, the air duct assembly includes a first air duct connected to a cooling fan. Airflow generated by the cooling fan enters and flows along the first air duct, passing through the inverter and control board. This dissipates heat and cools the inverter and control board.

[0048] By setting a first air duct passing through the inverter and the control board in the air duct assembly, the inverter and the control board can be cooled and dissipated through the first air duct to avoid overheating of the inverter and the control board, thereby ensuring the normal operation of the inverter and the control board.

[0049] In some technical solutions, exemplarily, the cooking box further includes: a door assembly, movably connected to the main body; a micro switch, connected to the door assembly, the micro switch is used to open or close the door assembly; the air duct assembly further includes: a second air duct, the second air duct is connected to the first air duct, and the second air duct extends in a direction toward the micro switch to dissipate heat from the micro switch.

[0050] This technical solution further defines the structure of the cooking chamber. The cooking chamber also includes a door assembly and a microswitch. The door assembly is movably connected to the main body, and the microswitch is connected to the door assembly. The microswitch is used to open or close the door assembly, thereby opening or closing the cooking chamber. To dissipate heat from the microswitch and ensure its proper operation, the present application further provides a second air duct in the air duct assembly. The second air duct is connected to the first air duct and extends toward the microswitch. This second air duct can direct airflow toward the microswitch through the second air duct to dissipate heat from the microswitch.

[0051] By setting a second air duct in the air duct assembly and setting the second air duct to extend in the direction toward the micro switch, the micro switch can be cooled through the second air duct to avoid overheating of the micro switch, so that the micro switch can work normally and the reliability of the micro switch is improved.

[0052] In some technical solutions, illustratively, the ratio of the cross-sectional area of ​​the first air duct to that of the second air duct ranges from 7:3 to 9:1.

[0053] In this technical solution, the ratio of the cross-sectional areas of the first and second air ducts is limited. In some embodiments, the ratio ranges from 7:3 to 9:1. This allows for a reasonable distribution of airflow within the first and second ducts, ensuring adequate heat dissipation and cooling for all components.

[0054] In a possible technical solution, the ratio of the cross-sectional area of ​​the first air duct to that of the second air duct is in the range of 8:2.

[0055] In some technical solutions, exemplarily, the air duct assembly further includes: a third air duct, connected to an end of the first air duct away from the heat dissipation fan, the third air duct passes through the microwave assembly to dissipate heat for the microwave assembly; a fourth air duct, connected to an end of the first air duct away from the heat dissipation fan, the fourth air duct extends in a direction toward the air frying assembly to dissipate heat for the air frying assembly.

[0056] In this technical solution, the structure of the air duct assembly is further defined. The air duct assembly also includes a third air duct and a fourth air duct. The third air duct is connected to the end of the first air duct facing away from the cooling fan, allowing a portion of the airflow in the first air duct to flow into the third air duct. The third air duct passes through the microwave assembly, allowing the airflow in the third air duct to dissipate heat from the microwave assembly, thereby preventing overheating. The fourth air duct is connected to the end of the first air duct facing away from the cooling fan, allowing a portion of the airflow in the first air duct to flow into the fourth air duct. The fourth air duct extends toward the air fryer assembly, allowing the airflow to be directed toward the air fryer assembly through the fourth air duct, thereby dissipating heat from the air fryer assembly and preventing overheating.

[0057] By setting the third air duct and the fourth air duct in the air duct assembly, the microwave assembly and the air frying assembly can be cooled through the third air duct and the fourth air duct respectively, so as to avoid overheating of the microwave assembly and the air frying assembly, enable the microwave assembly and the air frying assembly to work normally, and improve the reliability of the microwave assembly and the air frying assembly.

[0058] In some technical solutions, illustratively, the ratio of the cross-sectional area of ​​the third air duct to that of the fourth air duct ranges from 6:4 to 8:2.

[0059] In this technical solution, the ratio of the cross-sectional areas of the third and fourth air ducts is limited. In some embodiments, the ratio ranges from 6:4 to 8:2. This allows for a reasonable distribution of airflow within the third and fourth ducts, ensuring adequate heat dissipation and cooling for both the microwave and air fryer components.

[0060] In a possible technical solution, the ratio of the cross-sectional area of ​​the third air duct to that of the fourth air duct is in the range of 7:3.

DETAILED DESCRIPTION

[0081] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0082] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application 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.

[0083] The following describes a cooking box 100 and a cooking appliance provided according to some embodiments of the present application with reference to FIG. 1 to FIG. 14 .

[0084] In one embodiment of the present application, as shown in Figures 1, 2, 6, 8 and 10, a first aspect of the present application provides a cooking box 100, comprising: a main body 110 including a cooking cavity 111; an air frying assembly 120 for blowing hot air into the cooking cavity 111, the wall surface of the main body 110 having a plurality of receiving grooves 140, at least some of the receiving grooves 140 being recessed in a direction toward the cooking cavity 111, and at least some of the air frying assembly 120 being located in the receiving grooves 140 recessed in a direction toward the cooking cavity 111.

[0085] The cooking box 100 proposed in the present application can be used in a cooking appliance. The cooking box 100 includes a main body 110. The main body 110 includes a cooking cavity 111. The cooking cavity 111 is used to accommodate food. When the cooking appliance is running, the cooking appliance cooks the food in the cooking cavity 111.

[0086] Furthermore, the cooking chamber 100 includes an air frying assembly 120, which can air-fry the food in the cooking cavity 111. In some embodiments, when the air frying assembly 120 is in operation, the air frying assembly 120 can blow hot air into the cooking cavity 111. This hot air heats the food in the cooking cavity 111, achieving an air-frying cooking effect. The air frying assembly 120 is composed of multiple components, resulting in a certain thickness. To reduce the height of the air frying assembly 120 protruding from the outer wall of the main body 110, the present application provides multiple receiving slots 140 on the wall of the main body 110. By placing at least a portion of the air frying assembly 120 within the receiving slots 140, the height of the air frying assembly 120 protruding from the wall of the main body 110 can be reduced. In some embodiments, the wall of the main body 110 has a plurality of receiving slots 140, at least some of which are recessed toward the cooking cavity 111. Specifically, the walls of the receiving slots 140 extend into the cooking cavity 111, and at least some of the air fryer assembly 120 is located within the recessed receiving slots 140. This allows the air fryer assembly 120 to occupy a portion of the space in the cooking cavity 111, thereby reducing the height of the air fryer assembly 120 protruding from the wall of the main body 110. This reduces the distance between the outer shell of the cooking appliance and the wall of the cooking box 100, resulting in a narrower frame and a smaller size. The cooking box 100 proposed in this application can be used with a cooking appliance with a frame that can be narrowed to 30 mm.

[0087] Furthermore, the various components in the air fryer assembly 120 adopt a nested design, so that the height of the air fryer assembly 120 can be reduced. By adopting a nested design structure, the height of the air fryer assembly 120 can be reduced to 50 mm, further reducing the volume of the cooking utensil used by the cooking box 100.

[0088] By providing a receiving groove 140 recessed toward the cooking cavity 111 on the wall surface of the main body 110 and installing at least a portion of the air frying assembly 120 in the receiving groove 140, the height of the air frying assembly 120 protruding from the wall surface of the main body 110 can be reduced, thereby reducing the distance between the outer shell of the cooking appliance and the wall surface of the cooking box 100, so that the cooking appliance has a narrower frame, reduces the volume of the cooking appliance, makes the structure of the cooking appliance more compact, and is conducive to the miniaturization design of the product.

[0089] In some embodiments, for example, as shown in Figures 1, 2, 8 and 9, the air frying component 120 includes: a fan component 121 for forming an airflow; a heating component 122, the heating component 122 can heat the airflow formed by the fan component 121 to form hot air; the main body 110 includes: a first top plate 112, the first top plate 112 constitutes the top wall of the cooking cavity 111, a plurality of receiving grooves 140 including a first receiving groove 141 and a second receiving groove 142, the first receiving groove 141 and the second receiving groove 142 are provided on the first top plate 112, the first receiving groove 141 is recessed in a direction toward the cooking cavity 111, and the second receiving groove 142 is convex in a direction away from the cooking cavity 111, at least part of the fan component 121 is located in the first receiving groove 141, and at least part of the heating component 122 is located in the second receiving groove 142.

[0090] In this embodiment, the structure of the air frying assembly 120 is defined. The air frying assembly 120 includes a fan assembly 121 and a heating assembly 122. The fan assembly 121 is used to generate airflow, and the heating assembly 122 is capable of generating heat. When the heating assembly 122 is in operation, the heating assembly 122 heats the airflow generated by the fan assembly 121 to generate hot air. The fan assembly 121 can blow the hot air generated by the heating assembly 122 toward the cooking cavity 111 to air-fry the food in the cooking cavity 111.

[0091] In a possible embodiment, the heating component 122 is a heating tube, and the heating component 122 is located on a side of the fan component 121 facing the cooking cavity 111 so that the heating component 122 heats the airflow formed by the fan component 121 .

[0092] Furthermore, in order to reduce the height of the air fryer assembly 120 protruding from the wall surface of the main body 110, the present application provides a first top plate 112 having a plurality of receiving grooves 140 in the main body 110. By installing at least part of the air fryer assembly 120 in the receiving grooves 140, the height of the air fryer assembly 120 protruding from the wall surface of the main body 110 is reduced.

[0093] In some embodiments, the main body 110 includes a first top plate 112, which constitutes the top wall of the cooking cavity 111, and the multiple receiving grooves 140 include a first receiving groove 141 and a second receiving groove 142, and the first receiving groove 141 and the second receiving groove 142 are both arranged on the first top plate 112, wherein the first receiving groove 141 is recessed in the direction toward the cooking cavity 111, and the second receiving groove 142 is convex in the direction away from the cooking cavity 111, that is, the notch of the first receiving groove 141 faces the outside world, and the notch of the second receiving groove 142 faces the inside of the cooking cavity 111. The air frying assembly 120 is arranged at the top of the main body 110. The air frying assembly 120 includes a fan assembly 121 and a heating assembly 122, wherein at least part of the fan assembly 121 is located in the first accommodating groove 141, and at least part of the heating assembly 122 is located in the second accommodating groove 142. In this way, on the one hand, the height of the fan assembly 121 protruding from the first top plate 112 can be reduced to achieve the technical effect of a narrow side of the cooking appliance. On the other hand, the space occupied by the heating assembly 122 in the cooking cavity 111 can be reduced. Moreover, since the opening of the second accommodating groove 142 faces the cooking cavity 111, the heat generated by the heating assembly 122 can be dissipated more into the cooking cavity 111, thereby improving the heating efficiency.

[0094] Furthermore, the first top plate 112 has an opening connected to the cooking cavity 111. When the air frying component 120 is running, the fan component 121 forms an airflow, and the airflow blows toward the cooking cavity 111 through the opening of the first top plate 112. The heating component 122 generates heat to heat the airflow formed by the fan component 121 to form hot air. In this way, the food in the cooking cavity 111 can be heated by the hot air to achieve the air frying cooking effect.

[0095] By providing a first accommodating groove 141 that is recessed in the direction toward the cooking cavity 111 and a second accommodating groove 142 that is protruding in the direction away from the cooking cavity 111 in the first top plate 112, and installing at least part of the fan assembly 121 in the first accommodating groove 141, and installing the heating assembly 122 in the second accommodating groove 142, on the one hand, the height of the fan assembly 121 protruding from the first top plate 112 can be reduced, thereby achieving the technical effect of a narrow side of the cooking appliance. On the other hand, the space in the cooking cavity 111 occupied by the heating assembly 122 can be reduced, thereby improving the space utilization rate of the cooking cavity 111.

[0096] In some embodiments, for example, as shown in Figures 2 and 8 , the fan assembly 121 includes: a drive motor 123; and a plurality of fan blades 124 connected to the drive motor 123. The drive motor 123 is configured to drive the plurality of fan blades 124 to rotate to form an airflow. The main body 110 further includes: a second top plate 113, located on a side of the first top plate 112 facing away from the cooking cavity 111. The second top plate 113 is provided with a third receiving slot 143, which is recessed toward the cooking cavity 111. At least a portion of the drive motor 123 is located within the third receiving slot 143, and at least a portion of the fan blades 124 are located within the first receiving slot 141.

[0097] In this embodiment, the structure of fan assembly 121 is defined. Fan assembly 121 includes a drive motor 123 and a plurality of blades 124. Blades 124 are connected to drive motor 123. When fan assembly 121 is in operation, drive motor 123 drives blades 124 to rotate, generating airflow. Blades 124 are located on the side of drive motor 123 facing cooking chamber 111.

[0098] Furthermore, in order to reduce the height of the fan assembly 121 protruding from the wall of the main body 110, the present application also provides a second top plate 113 having a third accommodating groove 143 in the main body 110 to reduce the height of the fan assembly 121 protruding from the wall of the main body 110.

[0099] In some embodiments, the second top plate 113 is located on the side of the first top plate 112 away from the cooking cavity 111, and the second top plate 113 is provided with a third accommodating groove 143, which is recessed in the direction toward the cooking cavity 111, at least part of the drive motor 123 is located in the third accommodating groove 143, and at least part of the fan blades 124 are located in the first accommodating groove 141. In this way, on the one hand, the height of the fan assembly 121 protruding from the wall of the main body 110 can be reduced to achieve the technical effect of the narrow side of the cooking appliance. On the other hand, the drive motor 123 and the cooking cavity 111 can be separated by the second top plate 113, thereby reducing the impact of the high temperature in the cooking cavity 111 on the drive motor 123 and extending the service life of the drive motor 123.

[0100] By setting a second top plate 113 in the main body 110 and installing the drive motor 123 in a third accommodating groove 143 recessed toward the cooking cavity 111, the height of the drive motor 123 protruding from the wall of the main body 110 can be reduced, thereby reducing the height of the fan assembly 121 protruding from the wall of the main body 110, which is conducive to achieving the technical effect of a narrow side of the cooking appliance.

[0101] In some embodiments, for example, as shown in Figure 2, the cooking box 100 also includes: an exhaust plate 114, which is arranged on the side of the fan assembly 121 facing the cooking cavity 111, and the exhaust plate 114 is provided with a plurality of exhaust ports 115, which are used to discharge the airflow formed by the fan assembly 121 into the cooking cavity 111.

[0102] In this embodiment, the structure of the cooking chamber 100 is further defined. To ensure that the hot air is evenly discharged into the cooking cavity 111, the present application further provides an exhaust plate 114 in the cooking chamber 100 for exhausting air. The exhaust plate 114 is disposed on the side of the fan assembly 121 facing the cooking cavity 111. The exhaust plate 114 is provided with a plurality of exhaust ports 115, through which the hot air can be discharged into the cooking cavity 111. The plurality of exhaust ports 115 are evenly distributed on the exhaust plate 114. Thus, the flow direction of the hot air can be adjusted through the plurality of evenly distributed exhaust ports 115, so that the hot air can be evenly discharged into the cooking cavity 111.

[0103] Furthermore, there is a certain distance between the exhaust plate 114 and the first top plate 112, so that the hot air can first flow between the first top plate 112 and the exhaust plate 114, so that the hot air can fully flow to the locations of the multiple exhaust ports 115, and then be discharged into the cooking cavity 111 through the multiple exhaust ports 115, so that the hot air can be blown into the cooking cavity 111 more evenly.

[0104] By arranging an exhaust plate 114 on the side of the fan assembly 121 facing the cooking cavity 111, and arranging multiple exhaust ports 115 on the exhaust plate 114, hot air can be discharged into the cooking cavity 111 through the multiple exhaust ports 115, so that the hot air can be evenly discharged into the cooking cavity 111, so that the food can be evenly heated, thereby improving the cooking effect.

[0105] In some embodiments, for example, as shown in Figure 2, the cooking box 100 further includes: a microwave component 130, which is located on the side of the main body 110 away from the air frying component 120, and a plurality of feed ports 134 are provided on the side of the microwave component 130 facing the cooking cavity 111, and the microwave component 130 radiates microwaves into the cooking cavity 111 through the feed ports 134.

[0106] In this embodiment, the structure of the cooking chamber 100 is further defined. To provide the cooking appliance with multiple cooking modes and meet the diverse needs of users, the present application further provides a microwave assembly 130 in the cooking chamber 100. The microwave assembly 130 is capable of heating the food in the cooking cavity 111 with microwaves. The microwave assembly 130 and the air frying assembly 120 can operate independently or simultaneously, thereby enabling the cooking appliance to have multiple cooking modes to meet the diverse needs of users and improve user convenience.

[0107] Furthermore, the microwave assembly 130 is located on the side of the main body 110 facing away from the air fryer assembly 120. This allows the microwave assembly 130 and the air fryer assembly 120 to operate simultaneously, heating both sides of the food, improving the cooking effect. Furthermore, by placing the microwave assembly 130 on the side of the main body 110 facing away from the air fryer assembly 120, the cooking chamber 100 can be made more compact, facilitating a smaller product design. In one possible embodiment, the microwave assembly 130 is located at the bottom of the main body 110, while the air fryer assembly 120 is located at the top of the main body 110.

[0108] Furthermore, the structure of microwave assembly 130 is defined. Multiple feed ports 134 are provided on the side of microwave assembly 130 facing cooking cavity 111. Microwave assembly 130 radiates microwaves into cooking cavity 111 through these multiple feed ports 134. Compared to conventional structures that transmit microwaves into cooking cavity 111 through a stirring element, the present invention utilizes multiple feed ports 134 to radiate microwaves into cooking cavity 111. This achieves uniform microwave radiation within cooking cavity 111 while reducing the space occupied by microwave assembly 130. This, in turn, reduces the volume of cooking chamber 100, making cooking chamber 100 more compact and facilitating a miniaturized product design. Multiple feed ports 134 radiate microwaves into cooking cavity 111 separately, and the microwaves radiated by these multiple feed ports 134 overlap to achieve a balanced microwave field across various regions within cooking cavity 111, ensuring uniform heating of food. The bottom wall of the cooking cavity 111 is made of glass that is permeable to microwaves, so that the feeding port 134 can radiate microwaves into the cooking cavity 111 through the bottom wall of the cooking cavity 111 .

[0109] By installing a microwave assembly 130 within the cooking chamber 100, the cooking appliance can be equipped with a microwave heating cooking mode, meeting the user's diverse cooking needs and improving user convenience. By providing multiple feed ports 134 within the microwave assembly 130 and radiating microwaves into the cooking cavity 111 through these multiple feed ports 134, the microwaves radiated by the multiple feed ports 134 can be superimposed on each other, thereby balancing the microwave field across various areas within the cooking cavity 111 and evenly heating the food. Furthermore, the need for a stirring device can be reduced, reducing the space occupied by the microwave assembly 130 and, in turn, reducing the volume of the cooking chamber 100. This makes the cooking chamber 100 more compact and facilitates a miniaturized product design.

[0110] In some embodiments, exemplarily, as shown in Figures 2 and 12, the microwave component 130 includes: a microwave generating device 131, the microwave generating device 131 is used to generate microwaves; a plurality of waveguide plates 132, the plurality of waveguide plates 132 are combined to form a waveguide cavity 133, the microwave generating device 131 is connected to the waveguide cavity 133, and a plurality of feed ports 134 are provided on the top wall of the waveguide cavity 133.

[0111] In this embodiment, the structure of microwave assembly 130 is defined. Microwave assembly 130 includes a microwave generator 131 and multiple waveguide plates 132. Microwave generator 131 generates microwaves, and multiple waveguide plates 132 collectively form a waveguide cavity 133 for conducting microwaves. In some embodiments, waveguide cavity 133 communicates with microwave generator 131. Microwaves generated by microwave generator 131 first enter waveguide cavity 133, where they propagate toward cooking cavity 111. Multiple feed ports 134 are disposed on the top wall of waveguide cavity 133, through which microwaves are fed into cooking cavity 111 to facilitate microwave propagation.

[0112] By arranging a microwave generator 131 and a plurality of waveguide plates 132 in the microwave assembly 130 , the microwaves generated by the microwave generator 131 can be transmitted into the cooking cavity 111 through the waveguide cavity 133 enclosed by the plurality of waveguide plates 132 , thereby realizing microwave propagation.

[0113] In some embodiments, exemplarily as shown in FIG. 2 , the cooking box 100 further includes: a waveguide port 135 provided on the bottom wall of the waveguide cavity 133 , and the waveguide port 135 is used to connect the waveguide cavity 133 with the microwave generating device 131 .

[0114] In this embodiment, the structure of the cooking chamber 100 is further defined. To allow the microwaves generated by the microwave generator 131 to be transmitted into the waveguide cavity 133, a waveguide port 135 is provided on the bottom wall of the waveguide cavity 133. The waveguide port 135 connects the microwave generator 131 with the waveguide cavity 133, allowing the microwaves generated by the microwave generator 131 to be transmitted into the waveguide cavity 133 through the waveguide port 135, thereby achieving microwave propagation.

[0115] By arranging a waveguide port 135 connected to the microwave generator 131 on the bottom wall of the waveguide cavity 133 , the microwaves generated by the microwave generator 131 can be transmitted into the waveguide cavity 133 through the waveguide port 135 , thereby realizing microwave propagation.

[0116] In some embodiments, exemplarily as shown in FIG. 1 , FIG. 2 and FIG. 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 .

[0117] In this embodiment, the positions of the air fryer assembly 120 and the microwave assembly 130 are defined. 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 even heating and improving the cooking effect. Furthermore, compared to structures in which the air fryer assembly 120 and the microwave assembly 130 are located on the sides of the main body 110, the present invention places the air fryer assembly 120 and the microwave assembly 130 at the top and bottom of the main body 110, respectively. This allows the microwave assembly 130 and the air fryer assembly 120 to occupy the same installation space as other components in the cooking chamber 100, eliminating the need for additional installation space. This makes the cooking chamber 100 more compact and facilitates a miniaturized product design.

[0118] In some embodiments, exemplarily as shown in Figures 8 and 12, the cooking box 100 also includes: a cooling fan, which is arranged at the bottom of the main body 110; an air duct assembly 150, which is connected to the cooling fan, and the air duct assembly 150 extends along the wall of the main body 110 to dissipate heat from the components in the cooking box 100.

[0119] In this embodiment, the structure of the cooking chamber 100 is further defined. It is understood that when the cooking appliance is in operation, the temperature of the various components within the cooking chamber 100 rises. To prevent these components from malfunctioning due to overheating, the present application provides a cooling fan and an air duct assembly 150 within the cooking chamber 100 for dissipating heat from the various components within the cooking chamber 100. 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. The airflow generated by the fan assembly 121 is blown into and along the air duct assembly 150, dissipating heat from the components through which the air duct assembly 150 passes. The cooking chamber 100 also includes a cooling motor 182 for driving the cooling fan. The cooling motor 182 is capable of rotating the cooling fan to generate airflow. The cooking chamber 100 also includes a cooling fan bracket 181 for supporting the cooling fan. The air duct assembly 150 extends along the wall of the main body 110, and the extension path of the air duct assembly 150 passes through multiple components in the main body 110. Since there is a flowing airflow in the air duct assembly 150, the heat of the components it passes through can be taken away by the air duct assembly 150, so as to achieve the technical effect of dissipating heat to each component in the main body 110 through the cooling fan and the air duct assembly 150.

[0120] By setting a cooling fan and an air duct assembly 150 in the main body 110, the airflow flowing in the air duct assembly 150 can dissipate heat from the various components through which the air duct assembly 150 passes, thereby preventing the components in the main body 110 from overheating, ensuring that the cooking appliance can operate normally, and improving the service life of the product.

[0121] In some embodiments, exemplarily, as shown in Figures 9, 12 and 14, the cooking box 100 also includes: an inverter, which is arranged at the bottom of the main body 110; a control panel, which is arranged at the bottom of the main body 110, and the control panel is used to control the operation of the air frying component 120 and the microwave component 130; the air duct component 150 includes: a first air duct 151, the first air duct 151 is connected to the cooling fan, and the first air duct 151 passes through the inverter and the control panel to dissipate heat from the inverter and the control panel.

[0122] In this embodiment, the structure of the cooking chamber 100 is further defined. The cooking chamber 100 includes an inverter located at the bottom of the cooking chamber 100. The cooking appliance used in the cooking chamber 100 is connected to an external power source. The inverter adjusts the voltage supplied by the power source to meet the requirements of the cooking appliance.

[0123] Furthermore, the cooking box 100 further includes a control panel disposed at the bottom of the main body 110 for controlling the operation of the air fryer assembly 120 and the microwave assembly 130. The cooking box 100 further includes a control panel bracket 180 for supporting the control panel, and the control panel is mounted on the control panel bracket 180.

[0124] Understandably, when the cooking appliance is operating, the inverter and control board generate heat. To prevent overheating of the wall-mounted control board and inverter, the present application configures the air duct assembly 150 to pass through the inverter and control board to cool them. In some embodiments, the air duct assembly 150 includes a first air duct 151, which is connected to a cooling fan. The airflow generated by the cooling fan enters and flows along the first air duct 151, passing through the inverter and control board. This dissipates heat and cools the inverter and control board. The flow direction of the airflow within the first air duct 151 is shown in Figure 14.

[0125] By setting a first air duct 151 passing through the inverter and the control board in the air duct assembly 150, the inverter and the control board can be cooled and dissipated through the first air duct 151 to avoid overheating of the inverter and the control board, thereby ensuring the normal operation of the inverter and the control board.

[0126] In some embodiments, exemplarily, as shown in Figures 4, 5, 7, 8 and 11, the cooking chamber 100 further includes: a door assembly 160, movably connected to the main body 110; a micro switch 170, connected to the door assembly 160, the micro switch 170 is used to open or close the door assembly 160; the air duct assembly 150 further includes: a second air duct 152, the second air duct 152 is connected to the first air duct 151, and the second air duct 152 extends in a direction toward the micro switch 170 to dissipate heat from the micro switch 170.

[0127] In this embodiment, the structure of the cooking chamber 100 is further defined. The cooking chamber 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. The microswitch 170 is used to open or close the door assembly 160, thereby causing the door assembly 160 to open or close the cooking chamber 111. To dissipate heat from the microswitch 170 and ensure its proper operation, the present application further provides a second air duct 152 in the air duct assembly 150. The second air duct 152 is connected to the first air duct 151 and extends toward the microswitch 170. Thus, airflow can be directed toward the microswitch 170 through the second air duct 152 to dissipate heat from the microswitch 170.

[0128] By setting a second air duct 152 in the air duct assembly 150 and setting the second air duct 152 to extend in a direction toward the micro switch 170, the micro switch 170 can be cooled through the second air duct 152 to avoid overheating of the micro switch 170, so that the micro switch 170 can work normally and the reliability of the micro switch 170 is improved.

[0129] In some embodiments, illustratively, the ratio of the cross-sectional area of ​​the first air duct 151 to the cross-sectional area of ​​the second air duct 152 ranges from 7:3 to 9:1.

[0130] In this embodiment, the ratio of the cross-sectional areas of the first air duct 151 to the second air duct 152 is limited. In some embodiments, the ratio of the cross-sectional areas of the first air duct 151 to the second air duct 152 ranges from 7:3 to 9:1. This allows for a reasonable distribution of airflow within the first air duct 151 and the second air duct 152, ensuring adequate heat dissipation and cooling for all components.

[0131] In a possible embodiment, the ratio of the cross-sectional area of ​​the first air duct 151 to that of the second air duct 152 is in the range of 8:2.

[0132] In some embodiments, exemplarily, as shown in Figures 3 and 14, the air duct assembly 150 further includes: a third air duct, connected to an end of the first air duct 151 away from the heat dissipation fan, the third air duct passes through the microwave assembly 130 to dissipate heat for the microwave assembly 130; a fourth air duct 153, connected to an end of the first air duct 151 away from the heat dissipation fan, the fourth air duct 153 extends in a direction toward the air frying assembly 120 to dissipate heat for the air frying assembly 120.

[0133] In this embodiment, the structure of the air duct assembly 150 is further defined. The air duct assembly 150 further includes a third air duct and a fourth air duct 153. The third air duct communicates with the end of the first air duct 151 facing away from the heat dissipation fan, allowing a portion of the airflow within the first air duct 151 to flow into the third air duct. The third air duct passes through the microwave assembly 130, allowing the airflow within the third air duct to dissipate heat from the microwave assembly 130 and prevent overheating. The airflow within the third air duct is shown in FIG14 . The fourth air duct 153 communicates with the end of the first air duct 151 facing away from the heat dissipation fan, allowing a portion of the airflow within the first air duct 151 to flow into the fourth air duct 153. The fourth air duct 153 extends toward the air fryer assembly 120, allowing the airflow to be directed toward the air fryer assembly 120 through the fourth air duct 153, dissipating heat from the air fryer assembly 120 and preventing overheating.

[0134] By setting the third air duct and the fourth air duct 153 in the air duct assembly 150, the microwave assembly 130 and the air frying assembly 120 can be cooled through the third air duct and the fourth air duct 153 respectively, so as to avoid overheating of the microwave assembly 130 and the air frying assembly 120, enable the microwave assembly 130 and the air frying assembly 120 to work normally, and improve the reliability of the microwave assembly 130 and the air frying assembly 120.

[0135] In some embodiments, illustratively, the ratio of the cross-sectional area of ​​the third air duct to that of the fourth air duct 153 ranges from 6:4 to 8:2.

[0136] In this embodiment, the ratio of the cross-sectional areas of the third and fourth air ducts 153 is limited. In some embodiments, the ratio ranges from 6:4 to 8:2. This effectively distributes the airflow within the third and fourth air ducts 153, ensuring sufficient heat dissipation and cooling for both the microwave assembly 130 and the air fryer assembly 120.

[0137] In a possible embodiment, the ratio of the cross-sectional area of ​​the third air duct to that of the fourth air duct 153 is in the range of 7:3.

[0138] In one possible embodiment, the air fryer assembly 120 is mounted on top of the main body 110. The entire assembly 120 is nested, resulting in an overall height of 50 mm. The top of the main body 110 includes a protrusion (i.e., a receiving slot 140) for accommodating the air fryer assembly 120, reducing the cooking appliance's frame to no more than 30 mm, achieving a narrow frame. The main body 110 also includes an exhaust plate 114 with mesh holes (i.e., exhaust vents 115). Air heated by the air fryer assembly 120 is stirred by fan blades 124, passes through the mesh holes, and enters the cooking chamber 111, achieving a cooking effect.

[0139] In the above embodiment, the bottom of the main body 110 is equipped with a microwave system (i.e., microwave assembly 130), and the magnetron (i.e., microwave generating device 131) is fixed to the waveguide assembly 136. The waveguide assembly 136 is located at the center of the bottom of the main body 110 to achieve microwave excitation. Then, the microwaves diffuse from the waveguide assembly 136 through the waveguide port 135 into the waveguide cavity 133. The microwaves enter the cooking cavity 111 from the waveguide cavity 133 through several feed ports 134, achieving uniform microwave field intensity. This microwave system solution has a simple structure, small space occupation, simple manufacturability, and low cost. The microwave heating effect of the microwave system on the food is shown in Figure 13. When the microwave system performs microwave heating on the food, the food can be evenly heated to 83.8°C.

[0140] In the above embodiment, the air fryer assembly 120 and the magnetron generate a large amount of heat during operation. To ensure product safety, the cooking chamber 100 needs to actively and efficiently dissipate heat.
