Abstract

The invention discloses a mixer and an electromagnetic interference suppression circuit for the same. The electromagnetic interference suppression circuit comprises a first suppression unit, a first filter and a second suppression unit; the first suppression unit is connected between a zero line and a fire line of an inputted AC power supply; the first suppression unit is used for suppressing surge interference coming from the AC power supply; a first input terminal and a second input terminal of the first filter are connected to two terminals of the first suppression unit in parallel; the first filter suppresses an interference on a back stage circuit which coming from the AC power supply and an interference on the AC power supply which comes from the back stage circuit through suppressing a difference mode interference and a common mode interference ; a first terminal of the second suppression unit is connected to a first output terminal of the first filter, and a second terminal of the second suppression unit is connected to a second output terminal of the first filter; a third terminal of the second suppression unit is connected to a ground wire; the second suppression unit is used for suppressing the common mode interference and suppressing an interference signal in a preset frequency band in a process of testing harassing voltage so as to effectively suppress the electromagnetic interference generated by the mixer, particularly by a high speed blender.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electromagnetic interference suppression circuit for a mixer and a mixer with a mixer. Background technique [0002] The wall breaking machine can use high speed to break the cell wall of plant ingredients to fully release nutrients, which is very popular among consumers. However, because the motor speed of the broken wall machine is very high, 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 an electromagnetic interference suppression circuit for a mixer, which can effectively suppress the electromagnetic interference of the mixer. [0004] Another object of the present invent...
