Thus, the top wall 1212 of the rack body 121 and the bottom wall 111 of the electrical receiving cavity 112 of the base plate 11 are spaced apart from each other in the third direction, so as to define a main heat dissipation channel 125, wherein the main heat dissipation channel 125 extends along the first direction and communicates with the air inlet 1112 on the bottom wall 111 of the electrical receiving cavity 112. In a preferred embodiment, the air inlet 1112 is located on a side of the main heat dissipation air duct 125 near the mounting portion 123, and the air flow entering the main heat dissipation air duct 125 from the air inlet 1112 flows toward an end of the main heat dissipation air duct 125 away from the mounting portion 123 along a first direction, and then flows out from different air outlets.

The main board 14 is mounted on the rack top wall 1212 of the rack main body 121 toward the side of the electrical receiving cavity 112 and located in the main heat dissipation air channel 125, and is spaced apart from the air inlet 1112 in the first direction. In this way, the air flow entering the main heat dissipation duct 125 from the air inlet 1112 can take away the heat generated by the bottom plate 11 during the operation process.

It will be appreciated that the first filler element may also be formed from other deformable materials to meet different sealing requirements.

In this application, the support main body 121 includes three independently-arranged first air outlets 121a, second air outlets 121b and third air outlets 121c, and the first air outlets 121a, the second air outlets 121b and the third air outlets 121c respectively correspond to different components and parts, so that heat dissipation is performed on different components and parts simultaneously. The first outlet 121a and the second outlet 121b are respectively opened at two opposite ends of the bracket body 121 in the first direction, and the third outlet 121c is convexly disposed at one side of the bracket body 121 in the second direction and is located between the first outlet 121a and the second outlet 121b in the first direction.

Thus, the air flow in the main heat dissipation duct 125 can flow out through the first air outlet 121a, the second air outlet 121b and the third air outlet 121c, respectively, so as to dissipate heat of components at different positions. It can be understood that the number and the positions of the air outlets formed in the bracket main body 121 are not limited, and the air outlets can be arranged as required to meet different requirements.

Specifically, in some embodiments, the base assembly 10 includes the water pump 16, the water pump 16 is mounted on the mounting portion 123 of the rack main body 121 so as to be spaced apart from one side of the rack main body 121 in the first direction, and the first air outlet 121a is opened at a connection between the rack side wall 1214 and the rack top wall 1212 and faces the water pump 16. Therefore, the air flow in the main heat dissipation duct 125 flows out through the first air outlet 121a to cool the water pump 16. More specifically, the first outlet 121a extends lengthwise along the second direction, so as to have a larger outlet area. It can be understood that the shape of the first air outlet 121a is not limited, and may be set as required to meet different requirements.

In some embodiments, the second air outlet 121b is opened at an end of the rack top wall 1212 remote from the first air outlet 121a, and the base assembly 10 further includes a wind deflector 18 and an illumination unit 19. The air deflector 18 is disposed at one end of the bracket 12 where the second air outlet 121b is formed, the air deflector 18 extends lengthwise along the third direction from the end connected to the bracket body 121 to the other end, and the air deflector 18 forms an air guiding channel which communicates with the second air outlet 121b and extends lengthwise along the third direction. The lighting unit 19 is mounted on the air deflector 18, the side wall 113 of the cooking body is provided with a light through hole matched with the lighting unit 19, and the lighting unit 19 can provide a light source for the inner container assembly 30 through the light through hole.

Thus, the air in the main heat dissipation duct 125 flows into the air guiding channel through the second air outlet 121b, and further dissipates heat to the lighting unit 19. Specifically, in one embodiment, the air deflector 18 is integrally formed with the bracket 12, and in other embodiments, the air deflector 18 is separate from the bracket 12. Two lighting units 19 are arranged on the air deflector 18, and the two lighting units 19 are arranged at intervals along the third direction. It is understood that the number of the lighting units 19 is not limited, and can be set according to actual needs.

Further, the cross section of the air deflector 18 perpendicular to the first direction is approximately in a C shape with one side opened, and one side of the air deflector 18 in the first direction is provided with an opening extending along the third direction. When the air deflector 18 is coupled to the casing 90, the casing 90 can close the opening of one side of the air deflector 18 in the first direction to close the air guiding channel, thereby simplifying the manufacturing process and the manufacturing cost of the air deflector 18. In other embodiments, the cross-section of the air deflection plate 18 perpendicular to the first direction is substantially "square", so that the air deflection plate 18 can independently form a closed air deflection channel without relying on the housing 90.

In a preferred embodiment, the base assembly 10 further includes a second filling unit (not shown) formed of a deformable structure such as sponge, and the second filling unit is filled in the gap between the air deflector 18 and the casing 90, so as to improve the assembling sealing performance of the air deflector 18. It will be appreciated that the second filler element may also be formed from other deformable materials to meet different sealing requirements.

Thus, the air flow in the main heat dissipation duct 125 can flow out from the third air outlet 121c along the third direction, so as to dissipate heat from the circulating motor 32, thereby reducing the temperature of the circulating motor 32. The third air outlet 121c may be disposed at a position corresponding to the position of the circulation motor 32, so as to achieve a good heat dissipation effect.
