- the washing machine according to the fourth aspect of the present invention is the washing machine according to the second aspect, further comprising a tank discharge portion 685 for supplying the washing liquid from the foam generation chamber 623 to the storage tank, and from the outlet 684 to the storage tank.
- a bent portion 900 is provided in the flow path for guiding the washing water.
- the washing liquid since the bent portion becomes resistance to the flow of the washing liquid, the washing liquid is easily accumulated in the foam generation chamber. As a result, the washing liquid can collide with the stored washing liquid surface to the extent that the washing liquid bubbles from the discharge port, and bubbles can be efficiently generated by entraining the surrounding air.
- a washing machine is the washing machine according to the first aspect, in which the washing liquid is circulated and supplied from the circulation pump 610 to the foam generation unit 620, and from the circulation pump to the water tank.
- the circulation pump further includes a second circulation path 612 that circulates and supplies the washing liquid, and the circulation pump supplies the washing liquid to the first circulation path 611 and the second circulation path 612.
- the washing liquid can be discharged into the storage tank simultaneously with the generation of the foam and the dispersion of the foam into the storage tank.
- the wettability of the clothes is improved in a short time, the contact with the washing liquid is increased, and the clothes can be efficiently washed without unevenness. Therefore, the clothes can be efficiently washed by spraying the foam and the washing liquid simultaneously on the clothes with a simple configuration.
- the foam generation unit 620 has a water supply path 622 serving as a passage for guiding the washing liquid supplied from the circulation pump 610 to the foam generation chamber 623.
- the water supply channel 622 and the foam generation chamber 623 are partitioned by a partition wall 680.
