Washing machine

Abstract

The invention belongs to the technical field of washing machines, and discloses a washing machine which comprises an inner barrel, a sealing mechanism capable of reciprocating to open / close a drain hole and a jacking mechanism for pushing the sealing mechanism to open the drain hole, and the bottom of the inner barrel is provided with the drain hole. The sealing mechanism blocks the drainage hole to form a closed inner barrel for independently containing washing water; the ejection mechanism comprises a pushing piece capable of spirally ascending / descending, and the pushing piece is driven by the driving mechanism to spirally ascend, so that the sealing mechanism opens the drainage hole. According to the washing machine, the drainage hole is blocked through the sealing mechanism, so that the inner barrel can independently contain water for washing, the pushing piece spirally ascends to jack up the sealing mechanism upwards for drainage, positioning operation does not need to be conducted before drainage, control logic is simple, and implementation is easy.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine. Background technique [0002] Most of the existing washing machines include an outer tub and an inner tub disposed inside the outer tub, and a plurality of dewatering holes are arranged on the tub wall of the inner tub, so that the inner tub and the outer tub communicate with each other. When the washing machine is working, the outer tub contains washing water, and the inner tub contains the laundry to be washed. The washing water can exist between the inner tub and the outer tub, but this part of the washing water is not used. Moreover, as the working time of the washing machine increases, the dirt and lint in the washing water will remain in the space between the inner tub and the outer tub, which is difficult to clean, resulting in bacteria and odors caused by perennial use. In order to solve this problem, the prior art proposes a washi...

Problems solved by technology

However, the driving mechanism and the positioning structure for realizing the positioning of the inner tub need to be controlled by separate driving elements, and the control logic is complicated. The separate positioning structure also makes the assembly of the washing machine more cumbersome.

At the same time, the arrangement of multiple driving elements increases the manufacturing cost of the washing machine
