A commercial induction cooker with independent heat dissipation of wire reel and electric control board

Abstract

The invention relates to a commercial induction cooker in which a coil and an electric control board independently dissipate heat. It is characterized in that a mica wind cover is arranged under the wire reel, and a heat dissipation air chamber is formed between the mica wind cover and the concave ceramic plate, and a heat dissipation fan is arranged at the air inlet of the air chamber; the electric control board is arranged on the electric control board In the board casing, a fan is installed at the air inlet of the casing, and an air duct is formed between the air inlet of the casing and the air outlet of the casing. Two opening and closing valves are arranged in the air duct, and one end of the two opening and closing valves is hinged. on top. An annular mica air cover is arranged on the periphery of the wire reel of the present invention, and the mica air cover and the concave ceramic plate form an annular air duct to wrap the wire reel in its annular space, and a heat dissipation fan is installed on the side wall of the electromagnetic oven shell to be independent of the wire reel Heat dissipation; In addition, the electric control board is also designed as a sealed structure, so that the electric control board also realizes airtight and independent heat dissipation, so that the wire reel and the electric control board do not affect each other, which greatly improves the heat dissipation efficiency.

Description

technical field [0001] The invention belongs to the field of electromagnetic cookers, in particular to a commercial electromagnetic cooker in which a wire reel and an electric control board independently dissipate heat. Background technique [0002] The commercial induction cooker is a high-power electrical appliance. When the electrical appliance is working at high power, especially in the case of continuous high-temperature operation in summer, the temperature of the internal coil rises rapidly, and at the same time, there is a high pressure from the coil to the electric control board below. Radiant heat, because the diameter of the wire reel is relatively large and the heat generation is high, the cooling effect of the fan on the wire reel is not very obvious. Although it can guarantee its normal operation, it is still prone to burnout. The heat dissipation fans of the electric control board are blown from the bottom suction side. The air outlet of the fan is not directly...

AI Technical Summary

Problems solved by technology

The heat dissipation fans of the electric control board are blown from the bottom suction side. The air outlet of the fan is not directly aimed at the radiator, and the casing is simple and has no special air duct, and it cannot be sealed, which leads to poor heat dissipation. It is also unable to prevent insects and moisture, especially for high-power commercial stoves. The working environment is harsh. If you continue to work in a continuous high-temperature environment in summer, it is easy to burn out the electric control board.
