Abstract

The invention discloses a cooking machine and a cooking machine circuit. The cooking machine circuit includes: a motor; a motor driving circuit connected to an AC power supply and a motor respectively, and the motor driving circuit is used to drive the motor; a control chip, the control chip and the motor The drive circuit is connected, and the control chip is used to control the motor drive circuit; the switching power supply, the switch power supply is connected with the motor drive circuit and the control chip respectively to supply power to the motor drive circuit and the control chip; the first suppression circuit, the first suppression circuit is connected to the AC Between the power supply and the motor drive circuit, the first suppression circuit is used to suppress the interference from the AC power supply; the second suppression circuit is connected between the motor and the motor drive circuit, and the second suppression circuit is used to suppress the interference from the motor Interference, which can effectively suppress the interference from the AC power supply, effectively suppress the interference of the subsequent circuit to the AC power supply, and effectively suppress the electromagnetic interference from the motor.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a cooking machine circuit and the cooking machine. Background technique [0002] The cooking machine in the related art breaks the cell walls of the plant ingredients by controlling the motor to run at a high speed, and fully releases the nutrition, which is very popular among consumers. However, since the motor of the cooking machine rotates at a high speed, the problem of electromagnetic interference is very large. However, related technologies are difficult to solve this problem. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a cooking machine circuit, which can effectively suppress electromagnetic interference. [0004] Another object of the present invention is to provide a cooking machine. [00...
