Problems solved by technology

However, the problem of the related technology is that when heating with low power, the heating power rises slowly and the current sampling period is short, which leads to a relatively small current sampling value at startup, which easily causes the phenomenon that the induction cooker is misjudged as no pot due to too small current

Abstract

The invention discloses an electromagnetic heating system and its heating control method and heating control device. The method includes the following steps: obtaining a target duty ratio and obtaining a duty ratio adjustment mode; when adjusting the duty ratio in a gradual manner, firstly control The duty cycle of the control signal output to the IGBT tube is gradually reduced from the preset duty cycle to the target duty cycle, and the electromagnetic heating system is controlled to work according to the gradually reduced duty cycle, and after it is reduced to the target duty cycle The duty ratio of the control signal is kept at the target duty ratio, and the electromagnetic heating system works according to the target duty ratio; during the working process of the electromagnetic heating system, the gradually decreasing duty ratio or the corresponding target duty ratio The heating cycle samples the working current of the electromagnetic heating system, and controls the heating power of the electromagnetic heating system according to the sampled working current. Thus, an appropriate current value can be collected, preventing the electromagnetic heating system from misjudging that there is no pot due to too small current.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a heating control method for an electromagnetic heating system, a heating control device for an electromagnetic heating system, and an electromagnetic heating system. Background technique [0002] The induction cooker in the related art usually realizes low power by dropping waves, that is, in a low-power heating mode, low-power heating is realized with a certain duty cycle. However, the problem in the related technology is that when heating with low power, the heating power rises slowly and the current sampling period is short, so the current sampling value at startup is relatively small, which may easily cause the phenomenon that the induction cooker is misjudged as no pot due to too small current . [0003] Therefore, related technologies need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in t...
