Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a cooking box and a cooking utensil. Background Art

[0002] In the prior art microwave oven with hot air assembly, when the hot air assembly is in operation, the hot air motor in the hot air assembly generates heat, and the hot air motor has a motor coil. If the motor coil is overheated, it is easy to cause product failure. In the prior art, a heat dissipation device is usually separately provided in the microwave oven to dissipate the heat of the hot air assembly, but this structure increases the cost of the product. Summary of the invention

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

[0004] To this end, a first object of the present invention is to provide a cooking box.

[0005] The second object of the present invention is to provide a cooking appliance.

[0006] To achieve at least one of the above purposes, according to a first aspect of the present invention, a cooking box is proposed, comprising: a main body, including a cooking cavity; a hot air component, arranged on the main body, and used to blow hot air into the cooking cavity; a control component, arranged on the main body, and capable of controlling the operation of the hot air component, the control component including a heat dissipation fan; an air guide component, arranged on the main body, and capable of directing at least part of the airflow formed by the heat dissipation fan to the hot air component.

[0007] The cooking box proposed in the present application can be used in a cooking appliance. The cooking box includes a main body, and the main body includes a cooking cavity. The cooking cavity is used to accommodate food. During the operation of the cooking appliance, the cooking appliance heats the food in the cooking cavity. The cooking box also includes a hot air component, and the hot air component is arranged on the main body. When the cooking appliance heats the food, the hot air component can be operated to heat and cook the food. Specifically, the hot air component can form hot air and blow the hot air into the cooking cavity, and the hot air can heat the food. The cooking box also includes a control component, which is conductively connected to the hot air component, and the control component can control the operation of the hot air component. The control component can also control the operation of other electrical components in the cooking appliance. The control component itself includes a heat dissipation fan, and the heat dissipation fan can form an airflow.

[0008] Understandably, during the operation of the hot air component, the hot air component will generate heat, and if the hot air component is overheated, it will affect the normal operation of the cooking appliance. In order to dissipate heat for the hot air component, the present application also provides an air guide component in the cooking box, and the air guide component is used to dissipate heat for the hot air component. Specifically, the air guide component is provided in the main body, and the air guide component can guide at least part of the airflow formed by the heat dissipation fan to the hot air component. In this way, on the one hand, the hot air component can be cooled by the airflow, and on the other hand, there is no need to provide additional components for cooling the hot air component, thereby simplifying the product structure.

[0009] By providing an air guide component in the cooking box and guiding at least part of the airflow formed by the cooling fan to the hot air component through the air guide component, on the one hand, the hot air component can be cooled by the airflow, thereby improving the reliability and safety of the product; on the other hand, there is no need to provide additional components separately for cooling the hot air component, thereby simplifying the product structure and reducing the cost of the cooking appliance.

[0010] The cooking box according to the present invention may also have the following distinguishing technical features:

[0011] In some technical solutions, optionally, the cooking box also includes: a heat dissipation part, which is arranged on the wall of the main body, the heat dissipation part is recessed in the wall of the main body, at least part of the hot air component is located in the heat dissipation part, and the air guide component can blow air into the heat dissipation part to dissipate the heat of the hot air component.

[0012] In this technical solution, the structure of the cooking box is further defined. The cooking box also includes a heat dissipation portion, which is disposed on the wall surface of the main body and recessed in the wall surface of the main body, and at least part of the hot air component is located in the heat dissipation portion. When the hot air component is dissipated, the air guide component blows the airflow into the heat dissipation portion. Since the heat dissipation portion is recessed in the wall surface of the main body, the airflow can fully contact the hot air component in the heat dissipation portion to improve the heat dissipation effect of the hot air component.

[0013] In a possible technical solution, the heat dissipation portion is disposed on the top wall of the main body, and the hot air component is located above the main body.

[0014] In some technical solutions, optionally, the heat dissipation part includes: a heat dissipation groove, which is arranged on the wall of the main body, at least part of the hot air component is located at the groove of the heat dissipation groove, and the air guide component can blow air into the heat dissipation groove.

[0015] In this technical solution, the structure of the heat dissipation part is defined. The heat dissipation part includes a heat dissipation slot, which is arranged on the wall surface of the main body and recessed in the wall surface of the main body, at least part of the hot air component is located at the notch of the heat dissipation slot, the heat dissipation slot is close to the air outlet of the air guide component, and the air guide component can blow air into the heat dissipation slot. Since the heat dissipation slot is recessed in the wall surface of the main body and at least part of the hot air component is located at the notch of the heat dissipation slot, the hot air component can fully contact with the airflow in the heat dissipation slot, so as to improve the heat dissipation effect of the airflow on the hot air component.

[0016] In a possible technical solution, at least part of the hot air component is located in the heat dissipation slot, so that the hot air component can be in more complete contact with the airflow, further improving the heat dissipation effect of the hot air component.

[0017] In some technical solutions, optionally, the heat dissipation part also includes: an exhaust groove, which is connected to the heat dissipation groove, and the exhaust groove is located on the side of the hot air component, and the exhaust groove extends in a direction away from the air guide component.

[0018] In this technical solution, the structure of the heat dissipation part is further defined. The heat dissipation part also includes an exhaust slot, which is used for exhausting air. Specifically, the exhaust slot is connected to the heat dissipation slot, and the airflow in the heat dissipation slot can be discharged through the exhaust slot, so that the airflow can flow smoothly in the heat dissipation slot, reducing the resistance of the airflow in the heat dissipation slot. The exhaust slot is located on the side of the hot air component. When the airflow flows from the heat dissipation slot into the exhaust slot, the airflow in the exhaust slot can further dissipate the heat of the hot air component. The exhaust slot extends in a direction away from the air guide component. After the airflow flows from the heat dissipation slot into the exhaust slot, it flows in a direction away from the air guide component, avoiding mutual interference between the airflow blown into the heat dissipation slot by the air guide component and the airflow discharged into the exhaust slot by the heat dissipation slot, thereby reducing the resistance of the airflow flow.

[0019] In a possible technical solution, there are multiple exhaust slots, and the multiple exhaust slots are respectively located on both sides of the hot air component.

[0020] In some technical solutions, optionally, the cooking box further includes: an air guide slope, which is arranged on the wall of the main body, the air guide slope is located between the air outlet of the air guide component and the heat dissipation groove, and the air guide slope extends obliquely in the direction toward the heat dissipation groove.

[0021] In this technical solution, the structure of the cooking box is further defined. In order to enable the air guide component to discharge the airflow into the heat dissipation slot more smoothly, the present application further provides an air guide slope on the wall of the main body, the air guide slope is located between the air outlet of the air guide component and the heat dissipation slot, and the air guide slope extends obliquely in the direction toward the heat dissipation slot. The airflow discharged from the air outlet of the air guide component flows into the heat dissipation slot along the air guide slope, so that the loss of the airflow during the flow process can be reduced, so that the airflow can flow smoothly into the heat dissipation slot, and the heat dissipation efficiency can be improved.

[0022] In some technical solutions, optionally, the hot air component includes: a hot air motor, the hot air motor has a motor coil, and the motor coil is located at a notch of the heat dissipation slot.

[0023] In this technical solution, the structure of the hot air component is further defined. The hot air component includes a hot air motor, and the hot air component also includes fan blades. When the hot air component is running, the hot air motor drives the fan blades to rotate to form hot air. The hot air motor has a motor coil. When the hot air motor is running, the motor coil heats up. If the motor coil is overheated, it is easy to cause the hot air motor to malfunction. In order to dissipate the heat of the motor coil, the present application arranges the motor coil in the notch of the heat dissipation slot, and the airflow in the heat dissipation slot is in full contact with the motor coil to dissipate the heat of the motor coil.

[0024] In a possible technical solution, at least part of the motor coil is located in the heat dissipation groove, which further improves the heat dissipation effect of the heat dissipation groove on the motor coil.

[0025] In some technical solutions, optionally, the air guide assembly includes: an air guide duct, which is arranged on the main body, the air inlet of the air guide duct faces the cooling fan, and the air outlet of the air guide duct faces the heat dissipation slot.

[0026] In the technical solution, the structure of the air guide assembly is further defined. The air guide assembly includes an air guide duct, which is used to guide the airflow formed by the heat dissipation fan to the heat dissipation slot. Specifically, the air guide duct is arranged on the main body, the air inlet of the air guide duct faces the heat dissipation fan, and the air outlet of the air guide duct faces the heat dissipation slot. The airflow formed by the heat dissipation fan at least partially flows into the air guide duct and flows along the air guide duct in the direction toward the heat dissipation slot. After the airflow is discharged from the air outlet of the air guide duct, it flows into the heat dissipation slot along the air guide inclined surface.

[0027] By arranging an air guide duct in the air guide assembly, the airflow can be guided by the air guide duct, so as to guide the airflow formed by the heat dissipation fan to the heat dissipation slot, thereby realizing the heat dissipation of the hot air assembly.

[0028] In some technical solutions, optionally, the cross-sectional area of ​​the air duct gradually decreases along the direction from the air inlet of the air duct to the air outlet of the air duct.

[0029] In this technical solution, the air duct is further defined. Specifically, the cross-sectional area of ​​the air duct gradually decreases along the direction from the air inlet of the air duct to the air outlet of the air duct. It can be understood that the flow rate of the airflow in the air duct is related to the cross-sectional area of ​​the air duct. As the cross-sectional area of ​​the air duct decreases, the flow rate of the airflow in the air duct increases. In this way, the flow rate of the airflow discharged from the air outlet of the air duct can be increased, and the heat dissipation effect of the airflow on the hot air component can be improved.

[0030] In some technical solutions, optionally, the cooking box further comprises: a heat insulation board, which is arranged on the wall surface of the main body, the heat insulation board is used for heat insulation, and the heat insulation board is located between the wall surface of the main body and the air guide assembly.

[0031] In the technical solution, the structure of the cooking box is further defined. The cooking box also includes a heat insulation board, which is used to insulate the air guide assembly from the main body. Specifically, the heat insulation board is arranged on the wall surface of the main body, and the heat insulation board is made of a material with poor thermal conductivity so that the heat insulation board has a heat insulation function. The heat insulation board is installed between the wall surface of the main body and the air guide assembly, so that the main body and the air guide assembly can be insulated by the heat insulation board. It can be understood that when the cooking utensil cooks the food in the cooking cavity, the temperature in the cooking cavity is high. If the main body and the air guide assembly are not insulated by the heat insulation board, the heat in the cooking cavity will be radiated to the air guide assembly, and then the temperature of the air flow in the air guide duct will increase, which will reduce the heat dissipation effect of the air flow on the hot air assembly. In order to avoid the high temperature in the cooking cavity from affecting the air flow in the air guide assembly, the present application sets a heat insulation board between the air guide assembly and the main body to reduce the heat radiated by the main body to the air guide assembly and improve the heat dissipation effect on the hot air assembly.

[0032] In some technical solutions, optionally, the control component also includes: a mounting base, on which the cooling fan is mounted; an upper cover, which is snapped onto the mounting base, and the upper cover has an air outlet, which is arranged opposite to the cooling fan, and the air guide component is connected to the air outlet.

[0033] In this technical solution, a control component is defined. The control component includes a mounting seat and an upper cover, wherein the mounting seat has a mounting groove, and the cooling fan is installed in the mounting groove. The upper cover is buckled on the top of the mounting seat, and the upper cover has an air outlet, which is arranged opposite to the cooling fan, and the airflow formed by the cooling fan is discharged through the air outlet. The air guide component is connected to the air outlet, and the air outlet discharges the airflow into the air guide component. By arranging the mounting seat and the upper cover in the control component, the cooling fan can be installed and fixed.

[0034] In some technical solutions, optionally, the cooking box further includes: a rear plate connected to the main body, the rear plate is provided with a plurality of exhaust grilles, the exhaust grilles are located at one end of the rear plate close to the heat dissipation part, and the exhaust grilles are connected to the outside.

[0035] In this technical solution, the structure of the cooking box is further defined. The cooking box also includes a rear plate, which is connected to the main body and is provided with a plurality of exhaust grilles, which are connected to the outside world and are used to discharge the airflow discharged from the exhaust slot to the outside world. Specifically, the exhaust grilles are located on the side of the rear plate close to the heat dissipation part, and after the airflow flows out of the exhaust slot, it can be discharged to the outside world through the exhaust grilles, so that the air pressure in the cooking utensil can be kept stable, so that the airflow can flow normally in the heat dissipation part.

[0036] In a possible technical solution, there are multiple exhaust grilles, and the multiple exhaust grilles are arranged in sequence along the extension direction of the rear plate.

[0037] In some technical solutions, optionally, the cooking box further includes: an outer cover, the main body is located inside the outer cover, and the outer cover is provided with a plurality of ventilation holes, which are connected to the outside.

[0038] In this technical solution, the structure of the cooking box is further defined. The cooking box also includes an outer cover, and the main body is located inside the outer cover. The outer cover can protect the main body on the one hand, and can also improve the aesthetics of the cooking box on the other hand. The outer cover is provided with a plurality of vents, which are connected to the outside world, and the airflow discharged from the exhaust groove can be discharged to the outside world through the vents provided on the outer cover. In this way, the air pressure in the cooking utensil can be kept stable, and the airflow can flow normally in the heat dissipation part.

[0039] In some technical solutions, optionally, the hot air component is arranged at the top of the main body, and the control component is arranged at the bottom of the main body.

[0040] In this technical solution, the hot air component and the control component are defined. Specifically, the hot air component is arranged at the top of the main body, the heat dissipation part is arranged at the top wall of the main body, the control component is arranged at the bottom of the main body, and the air guide component is arranged at the side wall of the main body. The airflow formed by the heat dissipation fan in the control component flows to the heat dissipation part through the air guide component, and the airflow flows in the heat dissipation part to dissipate the heat of the hot air component. By arranging the hot air component and the control component at the top and bottom of the main body respectively, on the one hand, the space occupied by the two can be reduced, which is conducive to the miniaturization design of the product, and on the other hand, the air guide component can have sufficient extension space, which is conducive to the transmission of airflow by the air guide component.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

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

[0053] Refer to the following Figures 1 to 3 A cooking cabinet 100 and a cooking appliance provided according to some embodiments of the present invention are described.

[0054] In one embodiment according to the present application, Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a cooking box 100, including: a main body 110, including a cooking cavity 111; a hot air component 120, arranged on the main body 110, and the hot air component 120 is used to blow hot air into the cooking cavity 111; a control component 130, arranged on the main body 110, and the control component 130 can control the operation of the hot air component 120, and the control component 130 includes a heat dissipation fan 131; an air guide component 140, arranged on the main body 110, and the air guide component 140 can guide at least part of the airflow formed by the heat dissipation fan 131 to the hot air component 120.

[0055] The cooking box 100 proposed in the present application can be used in a cooking utensil. The cooking box 100 includes a main body 110, and the main body 110 includes a cooking cavity 111. The cooking cavity 111 is used to accommodate food. During the operation of the cooking utensil, the cooking utensil heats the food in the cooking cavity 111. The cooking box 100 also includes a hot air component 120, which is arranged on the main body 110. When the cooking utensil heats the food, the hot air component 120 can be operated to heat and cook the food. Specifically, the hot air component 120 can form hot air and blow the hot air into the cooking cavity 111, and the hot air can heat the food. The cooking box 100 also includes a control component 130, which is conductively connected to the hot air component 120, and the control component 130 can control the operation of the hot air component 120. The control component 130 can also control the operation of other electrical components in the cooking utensil. The control assembly 130 itself includes a heat dissipation fan 131, which can form an airflow.

[0056] Understandably, during the operation of the hot air component 120, the hot air component 120 will generate heat. If the hot air component 120 is overheated, it will affect the normal operation of the cooking appliance. In order to dissipate heat for the hot air component 120, the present application further provides an air guide component 140 in the cooking box 100, and the air guide component 140 is used to dissipate heat for the hot air component 120. Specifically, the air guide component 140 is provided on the main body 110, and the air guide component 140 can guide at least part of the airflow formed by the heat dissipation fan 131 to the hot air component 120. In this way, on the one hand, the hot air component 120 can be dissipated by the airflow, and on the other hand, there is no need to provide an additional component for dissipating heat for the hot air component 120, thereby simplifying the product structure.

[0057] By providing an air guide assembly 140 in the cooking box 100 and guiding at least part of the airflow formed by the cooling fan 131 to the hot air assembly 120 through the air guide assembly 140, on the one hand, the hot air assembly 120 can be cooled by the airflow, thereby improving the reliability and safety of the product; on the other hand, there is no need to provide additional components separately for cooling the hot air assembly 120, thereby simplifying the product structure.

[0058] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the cooking box 100 also includes: a heat dissipation portion 150, which is arranged on the wall of the main body 110, and the heat dissipation portion 150 is recessed in the wall of the main body 110. At least part of the hot air component 120 is located in the heat dissipation portion 150, and the air guide component 140 can blow air into the heat dissipation portion 150 to dissipate the heat of the hot air component 120.

[0059] In this embodiment, the structure of the cooking box 100 is further defined. The cooking box 100 further includes a heat dissipation portion 150, which is disposed on the wall surface of the main body 110 and recessed in the wall surface of the main body 110, and at least part of the hot air component 120 is located in the heat dissipation portion 150. When the hot air component 120 is dissipated, the air guide component 140 blows air into the heat dissipation portion 150. Since the heat dissipation portion 150 is recessed in the wall surface of the main body 110, the air flow can fully contact the hot air component 120 in the heat dissipation portion 150, so as to improve the heat dissipation effect of the hot air component 120.

[0060] In a possible embodiment, the heat dissipation portion 150 is disposed on the top wall of the main body 110 , and the hot air assembly 120 is located above the main body 110 .

[0061] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the heat dissipation part 150 includes: a heat dissipation slot 151, which is arranged on the wall of the main body 110, at least part of the hot air component 120 is located at the slot of the heat dissipation slot 151, and the air guide component 140 can blow air into the heat dissipation slot 151.

[0062] In this embodiment, the structure of the heat dissipation part 150 is defined. The heat dissipation part 150 includes a heat dissipation slot 151, which is provided on the wall surface of the main body 110 and recessed in the wall surface of the main body 110, at least part of the hot air component 120 is located at the notch of the heat dissipation slot 151, the heat dissipation slot 151 is close to the air outlet 135 of the air guide component 140, and the air guide component 140 can blow airflow into the heat dissipation slot 151. Since the heat dissipation slot 151 is recessed in the wall surface of the main body 110 and at least part of the hot air component 120 is located at the notch of the heat dissipation slot 151, the hot air component 120 can fully contact with the airflow in the heat dissipation slot 151, so as to improve the heat dissipation effect of the airflow on the hot air component 120.

[0063] In a possible embodiment, at least a portion of the hot air component 120 is located in the heat dissipation slot 151 , so that the hot air component 120 can be in more complete contact with the airflow, further improving the heat dissipation effect of the hot air component 120 .

[0064] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the heat dissipation portion 150 further includes an exhaust slot 152 , which is connected to the heat dissipation slot 151 . The exhaust slot 152 is located on the side of the hot air assembly 120 , and extends in a direction away from the air guide assembly 140 .

[0065] In this embodiment, the structure of the heat dissipation part 150 is further defined. The heat dissipation part 150 also includes an exhaust slot 152, which is used for exhausting air. Specifically, the exhaust slot 152 is connected to the heat dissipation slot 151, and the airflow in the heat dissipation slot 151 can be discharged through the exhaust slot 152, so that the airflow can flow smoothly in the heat dissipation slot 151, reducing the resistance of the airflow in the heat dissipation slot 151. The exhaust slot 152 is located on the side of the hot air component 120. When the airflow flows from the heat dissipation slot 151 into the exhaust slot 152, the airflow in the exhaust slot 152 can further dissipate heat for the hot air component 120. The exhaust slot 152 extends in a direction away from the air guide component 140. After the airflow flows from the heat dissipation slot 151 into the exhaust slot 152, it flows in a direction away from the air guide component 140, avoiding the airflow blown into the heat dissipation slot 151 by the air guide component 140 and the airflow discharged into the exhaust slot 152 by the heat dissipation slot 151. The resistance of the airflow is reduced.

[0066] In a possible embodiment, there are multiple exhaust slots 152 , and the multiple exhaust slots 152 are respectively located on both sides of the hot air assembly 120 .

[0067] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the cooking box 100 also includes: an air guide slope 112, which is arranged on the wall of the main body 110, and the air guide slope 112 is located between the air outlet 135 of the air guide component 140 and the heat dissipation groove 151, and the air guide slope 112 extends obliquely in the direction toward the heat dissipation groove 151.

[0068] In this embodiment, the structure of the cooking box 100 is further defined. In order to enable the air guide assembly 140 to discharge the airflow into the heat dissipation slot 151 more smoothly, the present application further sets an air guide slope 112 on the wall of the main body 110. The air guide slope 112 is located between the air outlet 135 of the air guide assembly 140 and the heat dissipation slot 151. The air guide slope 112 extends obliquely in the direction toward the heat dissipation slot 151. The airflow discharged from the air outlet 135 of the air guide assembly 140 flows into the heat dissipation slot 151 along the air guide slope 112. In this way, the loss of the airflow during the flow process can be reduced, so that the airflow can flow smoothly into the heat dissipation slot 151, and the heat dissipation efficiency is improved.

[0069] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the hot air assembly 120 includes a hot air motor 121 , the hot air motor 121 has a motor coil 122 , and the motor coil 122 is located at the notch of the heat dissipation slot 151 .

[0070] In this embodiment, the structure of the hot air component 120 is further defined. The hot air component 120 includes a hot air motor 121, and the hot air component 120 also includes fan blades. When the hot air component 120 is running, the hot air motor 121 drives the fan blades to rotate to form hot air. The hot air motor 121 has a motor coil 122. When the hot air motor 121 is running, the motor coil 122 generates heat. If the motor coil 122 is overheated, it is easy to cause the hot air motor 121 to malfunction. In order to dissipate the heat of the motor coil 122, the present application arranges the motor coil 122 in the notch of the heat dissipation slot 151, and the airflow in the heat dissipation slot 151 is in full contact with the motor coil 122 to dissipate the heat of the motor coil 122.

[0071] In a possible embodiment, at least a portion of the motor coil 122 is located in the heat dissipation slot 151 , which further improves the heat dissipation effect of the heat dissipation slot 151 on the motor coil 122 .

[0072] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the air guide assembly 140 includes an air guide duct 141 disposed on the main body 110 , an air inlet of the air guide duct 141 faces the heat dissipation fan 131 , and an air outlet 135 of the air guide duct 141 faces the heat dissipation slot 151 .

[0073] In this embodiment, the structure of the air guide assembly 140 is further defined. The air guide assembly 140 includes an air guide duct 141, which is used to guide the airflow formed by the heat dissipation fan 131 to the heat dissipation slot 151. Specifically, the air guide duct 141 is arranged on the main body 110, the air inlet of the air guide duct 141 faces the heat dissipation fan 131, and the air outlet 135 of the air guide duct 141 faces the heat dissipation slot 151. The airflow formed by the heat dissipation fan 131 at least partially flows into the air guide duct 141 and flows along the air guide duct 141 in a direction toward the heat dissipation slot 151. After the airflow is discharged from the air outlet 135 of the air guide duct 141, it flows into the heat dissipation slot 151 along the air guide inclined surface 112.

[0074] By providing an air guide duct 141 in the air guide assembly 140 , the airflow can be guided by the air guide duct 141 , so as to guide the airflow formed by the heat dissipation fan 131 to the heat dissipation slot 151 , thereby achieving heat dissipation of the hot air assembly 120 .

[0075] In some embodiments, optionally, the cross-sectional area of ​​the air duct 141 gradually decreases along the direction from the air inlet of the air duct 141 to the air outlet 135 of the air duct 141 .

[0076] In this embodiment, the air duct 141 is further defined. Specifically, along the direction from the air inlet of the air duct 141 to the air outlet 135 of the air duct 141, the cross-sectional area of ​​the air duct 141 gradually decreases. It can be understood that the flow rate of the airflow in the air duct 141 is related to the size of the cross-sectional area of ​​the air duct 141. As the cross-sectional area of ​​the air duct 141 decreases, the flow rate of the airflow in the air duct 141 increases. In this way, the flow rate of the airflow discharged from the air outlet 135 of the air duct 141 can be increased, and the heat dissipation effect of the airflow on the hot air component 120 can be improved.

[0077] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the cooking box 100 further includes: a heat insulation board 160 , which is disposed on the wall of the main body 110 . The heat insulation board 160 is used for heat insulation. The heat insulation board 160 is located between the wall of the main body 110 and the air guide assembly 140 .

[0078] In this embodiment, the structure of the cooking box 100 is further defined. The cooking box 100 further includes a heat insulation board 160, which is used to insulate the air guide assembly 140 from the main body 110. Specifically, the heat insulation board 160 is provided on the wall surface of the main body 110, and the heat insulation board 160 is made of a material with poor thermal conductivity so that the heat insulation board 160 has a heat insulation function. The heat insulation board 160 is installed between the wall surface of the main body 110 and the air guide assembly 140, so that the heat insulation board 160 can be used to insulate the main body 110 and the air guide assembly 140. Understandably, when the cooking appliance is cooking the food in the cooking cavity 111, the temperature in the cooking cavity 111 is relatively high. If the main body 110 and the air guide assembly 140 are not insulated by the heat insulation board 160, the heat in the cooking cavity 111 will be radiated to the air guide assembly 140, thereby causing the temperature of the airflow in the air guide duct 141 to rise, which will reduce the heat dissipation effect of the airflow on the hot air assembly 120. In order to prevent the high temperature in the cooking cavity 111 from affecting the airflow in the air guide assembly 140, the present application sets a heat insulation board 160 between the air guide assembly 140 and the main body 110 to reduce the heat radiated by the air guide assembly 140 from the main body 110, thereby improving the heat dissipation effect on the hot air assembly 120.

[0079] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the control component 130 also includes: a mounting base 132, and a cooling fan 131 is mounted on the mounting base 132; an upper cover 134, which is snapped onto the mounting base 132, and the upper cover 134 has an air outlet 135, and the air outlet 135 is arranged opposite to the cooling fan 131, and the air guide component 140 is connected to the air outlet 135.

[0080] In this embodiment, the control component 130 is defined. The control component 130 includes a mounting seat 132 and an upper cover 134, wherein the mounting seat 132 has a mounting groove 133, and the heat dissipation fan 131 is installed in the mounting groove 133. The upper cover 134 is buckled on the top of the mounting seat 132, and the upper cover 134 has an air outlet 135, and the air outlet 135 is arranged opposite to the heat dissipation fan 131, and the airflow formed by the heat dissipation fan 131 is discharged through the air outlet 135. The air guide component 140 is connected to the air outlet, and the air outlet 135 discharges the airflow into the air guide component 140. By arranging the mounting seat 132 and the upper cover 134 in the control component 130, the heat dissipation fan 131 can be installed and fixed.

[0081] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the cooking box 100 further includes: a rear plate 170 connected to the main body 110, the rear plate 170 is provided with a plurality of exhaust grilles 171, the exhaust grilles 171 are located at one end of the rear plate 170 close to the heat dissipation portion 150, and the exhaust grilles 171 are connected to the outside.

[0082] In this embodiment, the structure of the cooking box 100 is further defined. The cooking box 100 further includes a rear plate 170, which is connected to the main body 110. The rear plate 170 is provided with a plurality of exhaust grilles 171, which are connected to the outside world and are used to discharge the airflow discharged from the exhaust slots 152 to the outside world. Specifically, the exhaust grilles 171 are located on one side of the rear plate 170 close to the heat dissipation portion 150. After the airflow flows out of the exhaust slots 152, it can be discharged to the outside world through the exhaust grilles 171. In this way, the air pressure in the cooking utensil can be kept stable, so that the airflow can flow normally in the heat dissipation portion 150.

[0083] In a possible embodiment, there are multiple exhaust grilles 171 , and the multiple exhaust grilles 171 are arranged in sequence along the extension direction of the rear plate 170 .

[0084] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the cooking box 100 further includes: an outer cover, the main body 110 is located inside the outer cover, and the outer cover is provided with a plurality of vents, which are communicated with the outside.

[0085] In this embodiment, the structure of the cooking box 100 is further defined. The cooking box 100 further includes an outer cover, and the main body 110 is located inside the outer cover. The outer cover can protect the main body 110 on the one hand, and can also improve the aesthetics of the cooking box 100 on the other hand. The outer cover is provided with a plurality of vents, which are connected to the outside world. The airflow discharged from the exhaust slot 152 can be discharged to the outside world through the vents provided on the outer cover. In this way, the air pressure in the cooking utensil can be kept stable, so that the airflow can flow normally in the heat dissipation portion 150.

[0086] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the hot air component 120 is disposed on the top of the main body 110 , and the control component 130 is disposed on the bottom of the main body 110 .

[0087] In this embodiment, the hot air assembly 120 and the control assembly 130 are defined. Specifically, the hot air assembly 120 is arranged at the top of the main body 110, the heat dissipation portion 150 is arranged at the top wall of the main body 110, the control assembly 130 is arranged at the bottom of the main body 110, and the air guide assembly 140 is arranged at the side wall of the main body 110. The airflow formed by the heat dissipation fan 131 in the control assembly 130 flows to the heat dissipation portion 150 through the air guide assembly 140, and the airflow flows in the heat dissipation portion 150 to dissipate heat from the hot air assembly 120. By arranging the hot air assembly 120 and the control assembly 130 at the top and bottom of the main body 110 respectively, on the one hand, the space occupied by the two can be reduced, which is conducive to the miniaturized design of the product, and on the other hand, the air guide assembly 140 can have sufficient extension space, which is conducive to the air guide assembly 140 transmitting airflow.

[0088] In a possible embodiment, the cooking box 100 includes a hot air assembly 120, an electric control box (i.e., a control assembly 130), an air guide duct (i.e., an air guide pipe 141), a heat insulation board 160, and a rear plate 170. The hot air assembly 120 includes a hot air motor 121, a guide slope (i.e., an air guide slope 112), a pit (i.e., a heat dissipation slot 151), and a channel (i.e., an exhaust slot 152). The hot air motor 121 also has a hot air motor 121 coil (i.e., a motor coil 122). The electric control box includes a heat dissipation blade (i.e., a heat dissipation fan 131) and an air outlet 135. When the hot air function of the microwave oven (i.e., the cooking appliance) is turned on, the heat dissipation blades draw external cold air into the electric control box and discharge it from the air outlet 135. The discharged cold air blows along the air guide duct toward the guide slope. Under the guiding action of the guide slope, the cold air contacts the coil of the hot air motor 121 and takes away its heat and blows out from the channel. Finally, the air flow carrying heat is blown out from the microwave oven cover (i.e., the cover) and the air outlet grille (i.e., the exhaust grille 171) of the rear plate 170, thereby achieving the technical effect of dissipating heat for the hot air motor 121, thereby reducing the cost of the microwave oven with hot air function.
