- step S185 Turn off the driving mechanism 660. If the number of steps S2 performed in this drain filtering operation reaches the preset number of times, end the drain filtering operation; otherwise, return to step S182.
- the drive mechanism 660 drives the filter mechanism 620 to rotate, so that the filter impurities attached to the outer wall of the filter mechanism 620 can be peeled off under the double action of centrifugal force and turbulent water flow, and melt into the water in the filter cavity 610. It is helpful for the filter impurities attached to the outer wall of the filter mechanism 620 to fully fall off.
- the delivery pump 400 runs continuously for the fourth preset time period t 4 after being turned on for the first time, and continues to run for the fifth preset time period t 5 after each time it is turned on.
- the fourth preset duration t 4 is greater than the fifth preset duration t 5 .
- the specific values of the fourth preset time length t4 and the fifth preset time length t5 can be obtained through a large number of experiments in advance and directly written into the control program of the washing machine, the fourth preset time length t4 Specifically, when the filtering device 600 continues to perform filtering, the time elapsed during which most of the mesh holes on the filter net of the filtering mechanism 620 are covered by filtered impurities.
- the value of the fourth preset time period t4 can be relatively large.
- the value of the fifth preset time length t 5 is smaller than the fourth preset time length t 4 , so as to prevent the filter from being blocked and affecting the filtering process.
- the duration of continuous rotation of the filter mechanism 620 is the sixth preset duration t 6 , and the sixth preset duration t 6 is shorter than the fifth preset duration t 5 .
- the specific value of the sixth preset time length t6 can be obtained through a large number of experiments in advance and directly written into the control program of the washing machine, so as to ensure that the filter impurities attached to the filter mechanism 620 can be fully shed.
- the switching mechanism opens the drainage outlet, leading to the filtered water outlet and the drainage pipeline;
- step 12) performs step 12) to step 18) in a loop until the draining phase ends.
- the switching mechanism 712 keeps opening the circulating water outlet 702 and blocks the drain outlet 703, and the washing machine alternately performs the circulation filtering operation and the sewage discharge operation.
- the circulating filtering operation includes: the delivery pump 400 is turned on, the blocking mechanism 722 blocks the sewage outlet 705, and the water in the water storage cylinder 100 is circulated and filtered.
- the washing machine when the washing machine circulates and filters the washing/rinsing water during the washing/rinsing process, it also alternately performs the circulating filtering operation and the sewage discharge operation, so as to prevent a large amount of filter impurities from accumulating inside the filter device 600 and causing blockage.
- the specific steps of the circulation filtration operation are the same as those of the drainage filtration operation, and also control the conveying pump 400 to open intermittently for filtration, the difference is only that the switching mechanism 712 keeps the circulation water outlet 702 open during the circulation filtration operation instead of the drainage outlet 703 .
- the switching mechanism opens the circulating water outlet, leading to the filtered water outlet and the water storage cylinder;
- Steps 22) to 28) are executed in a loop until the washing/rinsing process is finished and the water is ready to be drained.
- the washing machine alternately performs drainage and filtration operations and sewage discharge operations during the drainage stage, and alternately performs cycle filtration operations and sewage discharge operations during the washing/rinsing process, so that the filtered impurities remaining in the filter device 600 can be passed through the sewage outlet 6103 in time. Discharge, to avoid the accumulation of filter impurities affecting the filter efficiency.
- control the transfer pump 400 to be turned on intermittently, and drive the filter mechanism 620 to rotate through the drive mechanism 660 during the shutdown period of the transfer pump 400, so that the filter impurities attached to the filter mechanism 620 are fully removed, and then Fully discharged during the execution of the blowdown operation.
- the filter device 600 can perform self-cleaning at any time during the running of the laundry program, avoiding the clogging of the filter device 600 and ensuring the water filtration efficiency of the washing machine.
