Abstract (en)
Embodiments of the present invention include a clothes processing machine, including: a tub which accommodates clothes; and a box which is fluid-connected to the tub and from which a liquid in the box is capable of flowing into the tub under gravity. The tub is capable of accommodating a liquid used for clothes processing, and the box is in communication with ambient atmosphere. A first end of a water delivery pipeline is in communication with an external clean water source through a water valve, and a second end is in fluid communication with the tub. The water delivery pipeline includes a constricted section. One end of a ventilation pipeline is fluid-connected to the constricted section of the water delivery pipeline or fluid-connected next to a down stream of the constricted section, and the other end of the ventilation pipeline is fluid-connected to the box. Water in the water delivery pipeline is less likely to enter the ventilation pipeline, or less water in the water delivery pipeline enters the ventilation pipeline. A utilization ratio of water is higher, and water resources are saved. In addition, a flow speed of water increases after the water passes through the constricted section, which makes it easier to overcome a fluid resistance at a down stream.
