Method and device for adjusting temperature of power device in household electrical appliance and household electrical appliance

Abstract

The invention relates to the field of household appliances, and discloses a method for adjusting the temperature of a power device in a household electrical appliance, a device for adjusting the temperature of the power device in the household electrical appliance, and the household electrical appliance. The method comprises the following steps of controlling the household electrical appliance tooutput at an output power; detecting the temperature of the power device; after the temperature of the power device is stable, adjusting the output power of the household electrical appliance, so thatthe power device is at an optimum temperature. The device corresponds to the method, and comprises a temperature detection device, a driving circuit and a controller. The household electrical appliance comprises the device. According to the method and device for adjusting the temperature of the power device in the household electrical appliance and the household electrical appliance, the household electrical appliance enables the power device to be at the optimum temperature by automatically adjusting the working power of the household electrical appliance, so that the function that the lowest temperature rise of the power devices can be realized, and the temperature rise of the different household appliances can be automatically adjusted are achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a method for adjusting the temperature of a power device in a household appliance, a device for adjusting the temperature of a power device in a household appliance, and the household appliance. Background technique [0002] Induction cooker is a new type of stove that uses the principle of electromagnetic induction heating to heat the pot body with eddy current. Inside the induction cooker, the AC voltage is converted into DC voltage by the rectifier circuit, and then the DC voltage is converted into high-frequency voltage by the control circuit. The high-speed changing current flowing through the coil will generate a high-speed changing magnetic field. The magnetic field lines in the magnetic field pass through the metal body at the bottom of the metal vessel to generate countless small eddy currents, which make the vessel itself heat up at a high speed, and then heat the co...

Problems solved by technology

However, the effect of using pots other than these two materials is not necessarily the best. At the same time, this method is also greatly affected by the distance between the disks. When the distance between the disks changes, the temperature rise will also become worse, that is, the induction cooker The temperature of the power device is not the lowest
