[0061] The heat dissipation duct 320 is used to dissipate heat for the entire oven. For example, it can dissipate heat for various components in the space between the box body 100 and the cavity 170, thereby ensuring the normal operation of the oven and ensuring the service life of the oven.

[0062] One end of the heat dissipation duct 320 is connected to the indoor space; the first fan 330 is disposed at the other end of the heat dissipation duct 320 .

[0079] The smoke removal module 400 is used to remove oil smoke in the air flow in the main air supply duct 210 and the auxiliary air supply duct 220, so that the second air duct assembly 200 can remove oil smoke while dissipating heat to the cavity 170, and when the smoke concentration is not less than the preset value, the smoke removal module 400 works, and when the concentration is less than the preset value, the smoke removal module 400 does not work, that is, when the smoke concentration value is not less than the preset value, the smoke removal module 400 is operated, thereby realizing intelligent oil smoke removal and reasonably and environmentally friendly allocating the working energy consumption of the oven.

[0081] Reference Figure 5 According to some embodiments of the present application, the smoke removal module 400 includes a catalytic device 410 and an electric adsorption device 420 .

[0082] The catalytic device 410 is used to catalytically decompose the oil smoke flowing through the smoke removal air duct; the electric adsorption device 420 is used to adsorb the oil smoke flowing through the smoke removal air duct. The air flow in the smoke removal air duct is removed from the oil smoke by the catalytic device 410 and the electric adsorption device 420, thereby ensuring the oven's effect on removing oil smoke and reducing oil fume pollution. Moreover, the catalytic device 410 catalytically decomposes the oil smoke, and the electric adsorption device 420 adsorbs the oil smoke. Both smoke removal methods do not require replacement and can permanently treat the oil smoke, thereby ensuring the oven's long-term treatment effect on the oil smoke.

[0083] The catalytic device 410 is arranged on the smoke removal air duct, specifically, the catalytic device 410 is arranged between the smoke removal air duct and the cavity 170, for example, the catalytic device 410 is connected between the cavity 170 and the main air supply duct 210; the electric adsorption device 420 is arranged on the smoke removal air duct, specifically, the electric adsorption device 420 is arranged in the auxiliary air supply duct 220, and the electric adsorption device 420 is arranged adjacent to the air outlet of the second fan 230, so that the oil smoke extracted by the second fan 230 passes through the electrostatic adsorption module as soon as possible, ensuring the adsorption effect, preventing the oil smoke from spreading to other components of the oven, and ensuring the normal operation of the oven.

The shell 414 is formed by connecting multiple plates and has a double-opening cavity structure. The heating element 413 can be a metal heating tube or a glass heating tube.

[0086] The first catalytic module 411 and the second catalytic module 412 are both used to decompose and catalyze the oil smoke. When the oil smoke passes through the first catalytic module 411 and the second catalytic module 412, it is catalytically decomposed into carbon dioxide and water, and at the same time achieves the effect of removing odor. Therefore, the oven can achieve pollution-free and environmentally friendly oil smoke removal, avoid polluting the atmosphere and user health, and the oil smoke removal structure is a chemical catalytic method, which can be used permanently to ensure the long-term oil smoke removal effect of the oven.

Therefore, while maintaining the independence of the two ducts and ensuring their respective heat dissipation effects, the space between the box and the cavity is reasonably utilized, which can reduce the volume of the box; at the same time, the area occupied by the heat dissipation duct on the horizontal plane is guaranteed, ensuring its overall heat dissipation effect on the oven and its heat dissipation effect on the space between the box and the cavity; at the same time, it can also ensure that the heat dissipation of the heat insulation board by the heat dissipation duct, thereby ensuring that the heat insulation board isolates the heat from the cavity and the space between the cavity and the box.
