Background

At present, the EMI (Electromagnetic Interference) modules in the frequency conversion washing machine on the market are independent, and the current frequency conversion washing machine generally adopts the EMI module independent filtering technology.

However, when power other than the frequency conversion control system needs to be increased, the power of the EMI system is higher, and a large part of the higher power does not contribute to the EMI of the whole EMI system, which is a waste of typical design. For another example, fig. 2 is a schematic diagram illustrating an installation and wiring manner of an EMI device of a related art inverter washing machine, and as can be seen from fig. 2, the installation and wiring manner of the EMI device of the related art inverter washing machine is complicated, thereby reducing production efficiency.
