The water entering the outer tub 120 again enters the filter assembly 300 through the valve body 400, thereby forming a cycle. After heating the water to the set temperature for a certain period of time, the circulation heating is stopped, and at this time, a certain amount of water is stored in the inside of the water collecting box 500.

And (3) a flock removal stage: in the dewatering stage of the washing machine, the valve body 400 is in an opened state, the impeller in the pump body assembly 200 is started to reversely rotate, water in the water collecting box 500 is pumped into the filter assembly 300, and filings on the filter screen 320 are flushed into the valve body and flow out through the drainage pipeline.

The circulating heating can be realized through the positive and negative rotation of the impeller in the pump body assembly 200, the heating speed of the water body can be effectively improved by heating the circulating flowing water body, the heating speed is improved, the circulating heating device can be suitable for a washing machine with larger washing capacity, the filtering assembly 400 can play a role in filtering filings, the heating efficiency is greatly improved, and the filtering effect is effectively improved.
