Drainage control device for washing machine and washing machine

Abstract

The invention discloses a drainage control device for a washing machine and the washing machine. The washing machine comprises an outer drum and an inner drum arranged in the outer drum; the inner drum is used for containing water, first drainage holes are formed in the upper portion of the drum body of the inner drum, second drainage holes are formed in the bottom of the inner drum, and sealing valves for controlling opening / closing of the second drainage holes are further arranged corresponding to the second drainage holes. The sealing valves are electric control sealing valves and are arranged at the bottom of the outer drum, comprise valve plugs for movably opening / closing the second drainage holes and driving devices for driving the valve plugs to move, and the sealing valves are installed at the bottom of the outer drum, and sealed with the outer drum. The washing machine is provided with an inner drum rotation locating device to locate the sealing valves and the second drainageholes. By means of the full-automatic washing machine, no water exists between the inner drum and the outer drum during washing and rinsing, during drainage, washing water is drained from the bottom of the inner drum, during dewatering, water removed from clothes is drained from the upper portion of the inner drum, and the full-automatic washing machine has the advantages that the water is saved,drainage is quick and thorough, and no foreign matter is left.

Description

[0001] This application is a divisional application of Chinese patent application CN201410617861.4. [0002] Original application date: 2014-11-05 [0003] Original application number: CN201410617861.4 [0004] Name of the invention-creation in the original application: a fully automatic washing machine Technical field [0005] The invention relates to the field of washing machines, in particular to a bottom drainage control device with an inner tub with a function of holding water and a washing machine. Background technique [0006] Traditional pulsator washing machine, such as figure 1 As shown, it generally includes a pulsator 1', an inner barrel 2', an outer barrel 3', and a box body 4'which are sequentially arranged from the inside to the outside. The pulsator 1'is arranged at the center of the bottom of the inner barrel 2'and can be driven by the driving device 5. 'Drive the rotation. The top of the inner tub 2'is provided with a balance ring 6', the side wall of the inner tub ...

AI Technical Summary

Problems solved by technology

[0012] Although the above-mentioned structure has been improved compared to the traditional washing machine, there is no water between the inner and outer tubs, so that the inner tub can be used as a water tank, which overcomes the defects of the traditional washing machine, and makes the improved washing machine have the characteristics of saving water, and because the washing water no longer enters the inner and outer tubs time, to avoid the breeding of bacteria between the inner and outer barrels, and to solve the problem of cross-contamination of clothes, but there are still the following defects: the drainage can only rely on driving the inner barrel to rotate so that the water is discharged from the upper outlet hole, and the drainage time is long; in addition, during the drainage process, The driving device is required to work, and the power consumption is relatively high; finally, when used for a long time, sedimentary dirt such as sediment particles cannot be discharged, and accumulate in the inner bucket. If the accumulation is too much, bacteria will easily breed and contaminate the clothes for the second time, and even wear out the clothes or Components in the inner tub, such as impeller shaft seal components, etc.
