Title: DRAINAGE STRUCTURE OF WASHING MACHINE AND DRAINAGE METHOD THEREFOR
Abstract:
A drainage structure of a washing machine and a drainage method therefor. An inner tub (1) is mounted in a shell of the washing machine; the inner tub (1) is a conical tub with a small diameter at one end and a large diameter at the other end; the large end of the inner tub (1) is provided with a drainage passage (32); one end of the drainage passage (32) is communicated with the large end of the inner tub (1), and the other end thereof penetrates through the inner tub (1) via the center of the large end and is communicated with a drainage pipe (31) of the washing machine. The inner tub (1) rotates at a certain rotating speed, so that washing water in the inner tub (1) flows to the large end along the inner wall of the conical inner tub (1) under the centrifugal force; when flowing to the large end of the inner tub (1), water flows from the center of the large end of the inner tub (1) along the drainage passage (32) provided at the large end, and flows out of the washing machine along the drainage pipe (31) to achieve discharge of washing water from the inner tub (1). By means of the setting and the method, the effects of sealing the inner tub (1) in the rotation process of the inner tub (1) and normally discharging water in the inner tub (1) when a drainage valve is opened during drainage are achieved, and the purpose of normal drainage of the washing machine having dual effects that the inner tub (1) can rotate and hold water is achieved. Moreover, no outer tub is required to be sleeved outside the inner tub (1), improving the washing capacity of the washing machine.
