Abstract

The embodiment of the invention relates to the technical field of control circuits and particularly discloses a motor safety circuit and a stirrer. The motor safety circuit comprises a first resistance-capacitance voltage reduction circuit, a motor control circuit, a blocking circuit and a second resistance-capacitance voltage reduction circuit, and the first resistance-capacitance voltage reduction circuit, the motor control circuit and the blocking circuit are connected; the first resistance-capacitance voltage reduction circuit comprises a first voltage stabilizing diode, the second resistance-capacitance voltage reduction circuit comprises a second voltage stabilizing diode, the motor control circuit comprises a switch circuit, a controller and a charging circuit, and the controller isconnected with the blocking circuit, the switch circuit and the charging circuit separately; the charging circuit is connected with the switch circuit, and the second resistance-capacitance voltage reduction circuit is connected with the charging circuit; when the switch circuit is in a disconnected state, a motor is in a non-working state, the first voltage stabilizing diode is in parallel connection with the charging circuit, and the controller controls connection and disconnection of the blocking circuit by outputting a square wave signal. In this way, the power consumption amount of household appliances in a standby state can be lowered.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of control circuits, in particular to a motor safety circuit and a mixer. Background technique [0002] The mixer, which is common in kitchen appliances, works by driving a sharp knife head to rotate through the AC motor safety circuit to cut or crush food. Therefore, mixers have higher safety requirements in small household appliances. [0003] In the process of realizing the present invention, the inventor of the present invention found that due to circuit design and other reasons in the existing mixer, the power consumption in the standby state is relatively large during use. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the main purpose of the embodiment of the present invention is to provide a motor safety circuit and a mixer, which can reduce the power consumption of household appliances in the standby state. [0005] In order t...
