Abstract

The invention provides a power conditioning circuit of a resistance-type hot plate, and a cooking utensil. The power conditioning circuit of a resistance-type hot plate comprises a power module, a resistance-type hot plate module, a power driving module, a sampling module, and a microprocessor. The resistance-type hot plate module comprises at least a resistance-type hot plate. The resistance-type hot plate module is connected with the power module. The power driving module is connected with the resistance-type hot plate module. The power driving module is used to control whether the resistance-type hot plate module heats. The sampling module is connected with the power module. The sampling module is used to sample power supply signals of the power module. The microprocessor is connected with the power driving module and the sampling module. The microprocessor controls operating states of the power driving module according to the power supply signals, so as to adjust power of the resistance-type hot plate module in real time. The technical scheme realizes real-time accurate adjustment on power of the resistance-type hot plate, and improves use experience of users.

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 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 determ...
