Abstract

The invention provides a power regulating circuit of a resistance heating plate and a cooking appliance, wherein the power regulating circuit of a resistance heating plate includes: a power supply module; a resistance heating plate module including at least one resistance heating plate and an auxiliary resistor The resistance heating plate module is connected to the power supply module; the power drive module is connected to the resistance heating plate module, and the power drive module is used to control whether the resistance heating plate module is heated; the sampling module is connected to the power supply module to sample The module is used to sample the power supply signal of the power supply module; the microprocessor is connected to the power drive module and the sampling module, and the microprocessor controls the working state of the power drive module according to the power supply signal to adjust the power and auxiliary power of the resistive hot plate module in real time Load power of the resistive hot plate. Through the technical solution of the invention, the effect of the microprocessor controlling the power drive module according to the output signal of the sampling module is realized, and the power range of the resistance heating plate module is increased.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a power regulating circuit of a resistance hot plate and a cooking utensil. Background technique [0002] In the related art, during the working process of a cooking appliance equipped with a resistance heating plate, the working time of the resistance heating plate is usually controlled by a relay, and then the average power of the resistance heating plate is determined, but the above-mentioned control method and circuit structure There are the following disadvantages: [0003] (1) When the resistive hot plate is controlled by the relay, since the relay is mechanically controlled, the switching process is relatively slow, and precise control of the resistive hot plate cannot be realized; [0004] (2) When some relays are controlled by a drive circuit, the turn-off process of the relay can only be adjusted by adjusting the turn-off time of the drive circuit, so as to de...
