referring to fig. 4, when the circulation motor 3 is started to rotate the circulation pump wheel 17, the washing water enters the filter unit 41 through the inlet 111 and the guide inlet 4111, and the water flow hits the lower middle portion of the impeller 43 to rotate the impeller 43 at a first rotation speed and flows into the circulation water inlet 131 through the filter fence 44 and the filter net 412. In this process, the washing water flowing into the circulating water port 131 is filtered through the filtering fence 44 and the filtering net 412, the excessive accumulation of the thread scraps on the filtering net 412 is avoided by designing the filtering fence 44, the thread scraps are uniformly distributed on the filtering fence 44 through the rotation of the impeller 43, and the situation that the thread scraps block the part of the filtering net 412 corresponding to the circulating water port 131, so that water cannot enter or is very difficult to enter, and water circulation cannot be performed is avoided.
When the washing machine pump is used for draining water, the working process of the washing machine pump is as follows:
referring to fig. 3, the drainage motor 2 is started to drive the drainage pump wheel 16 to rotate, the washing water flows into the filter part 41 through the water inlet 111 and the diversion inlet 4111, the water flow impacts the middle lower part of the impeller 43 to rotate the impeller 43 at a second rotation speed, the second rotation speed is greater than the first rotation speed due to the large water flow during drainage, and the washing water flows into the drainage port 121 through the cavity inlet 42 under the action of the impeller 43 rotating at a high speed, specifically, the water flow direction refers to the arrow direction shown in fig. 3. In the process, the impeller 43 rotating at high speed can effectively drive the filter screen 412 and the thread scraps on the filter fence 44 to flow into the water outlet 121 along with the water flow through the cavity inlet 42, so that the self-cleaning of the washing machine pump is realized, and a user does not need to open the pump cover 15 to clean the thread scraps in the filter part 41.
The embodiment also provides a washing machine, which comprises the washing machine pump. By adopting the washing machine pump, the washing machine can filter washing water during water circulation, automatically clean the washing machine pump during water drainage, and automatically discharge filtered thread scraps out of the washing machine pump during water circulation; the installation process is simple, the occupied space of the washing machine pump is reduced, and the production cost is reduced.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
