after the power is connected to the wire inlet, when the pot needs to be heated, the temperature control knob 311 on the control panel 31 for controlling the heating power of the first heating device 4 or/and the second heating device 5 is rotated, the power panel 2 receives the electric signal, outputs high current to the first heating device 4 or/and the second heating device 5, and uses the high-frequency current to pass through the coils built in the first heating device 4 or/and the second heating device 5, thereby generating countless closed magnetic field force, enabling the pot body 8 to automatically and rapidly heat, and further heating food in the pot. The power panel 2 simultaneously outputs voltage signals to the first fan 6 and the second fan 7, so that the first fan 6 and the second fan 7 are operated, the first fan 6 sucks cooling air from the bottom air suction part 123 corresponding to the position of the first fan 6 on the lower case 12 and the side air suction part 124 arranged on the first side wall of the upper case 13, blows out the cooling air from the first air inlet 62, the second air inlet 63 and the third air inlet 64 which are separated by the first air deflector 138 and the second air deflector 139, and as shown in fig. 7, the cooling air blown out from the first air inlet 62 is guided into the power panel 2, a first air duct s1 is formed by a path through which cooling air flows, the cooling air flows out from a gap between the second fan 7 and the first heating device 4 under the blocking of the upper shell 13, the first heating device 4 and the second fan 7, and the cooling air passes through the second heating device 5 to take away heat of the second heating device 5 and dissipate heat of the power panel 2 and the second heating device 5; as shown in fig. 8, the second air guiding plate 139 guides the cooling air from the second air inlet 63 into the control panel 3, a path through which the cooling air flows forms a second air channel s2, when the cooling air flows through the control panel 3, the cooling air takes away heat of the control panel 3 and part of heat conducted to the second air channel s2 by the first heating device 4 and the second heating device 5, and the cooling air flows out through the second air outlet 128 and the side air outlet 126; as shown in fig. 9, the cooling air flows in through the third air inlet 64 between the first air deflector 138 and the second air deflector 139, most of the cooling air flows through the first heating device 4 and the second heating device 5, takes away the heat released by the first heating device, flows out through the side air outlet 126 and the bottom air outlet 125, and part of the cooling air flows through the power board 2 under the guidance of the first air deflector 138 and joins the first air duct s 1; after the cooling air in the first air duct s1 flows out from the gap between the second fan 7 and the first heating device 4, the cooling air merges with the third air duct s3 and flows out from the side air outlet 126 and the bottom air outlet 125; as shown in fig. 10, when the second fan 7 operates, the cooling air is sucked from the fourth air inlet 127 of the lower shell 12, and is accelerated to circulate under the driving of the fan blades of the second fan 7, and the cooling air flows to the second heating device 5 under the guiding of the air guiding cover 137, and joins with the third air duct s3, and finally flows out from the side air outlet 126 and the bottom air outlet 125, so that a large amount of air can be blown to the heat dissipation area, and a separate heat dissipation path is designed for each area, thereby effectively improving the heat dissipation effect, and ensuring the service life and the use safety of each component of the heating cooker.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
