Washing machine water drainage control method

Abstract

The invention discloses a washing machine water drainage control method. The washing machine comprises an outer barrel and an inner barrel arranged in the outer barrel. The inner barrel is a water-containing barrel, the upper part of the barrel body of the inner barrel is provided with a water outlet hole, and the rotating speed of the inner barrel is controlled by stages by means of detecting the change case of the residual water amount of the inner barrel; or the rotating speed of the inner barrel is controlled by stages in dependence on the water drainage time, and the longer the water drainage time is, the higher the rotating speed of the inner barrel is controlled in the next stage. A flow sensor is used for measuring the amount of water which is discharged from the washing machine, the residual water amount of the inner barrel is obtained by subtracting the discharged water amount from the water intake amount of the washing machine, or the residual water amount of the inner barrel is detected by a weighing sensor. The water intake amount of the washing machine is measured through a water intake flow sensor or the weighing sensor or other ways. The weighing sensor is installed on the joint of a suspension rod and the casing of the washing machine, or is installed on the joint of the suspension rod and an outer barrel suspension rod base, or is installed on a bottom foot of the casing of the washing machine. According to the invention, the water drainage speed is fast, and the water drainage efficiency is high.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a control method of the washing machine, in particular to a control method for draining water from the upper part of the inner tub by using the rotating speed of the inner tub. Background technique [0002] The fully automatic washing machines that are more commonly produced and used at present include an inner tub for washing and an outer tub for water storage. There is no seal between the inner tub and the outer tub to form an ineffective space for water storage, thereby increasing the water consumption for washing ordinary clothes. [0003] Such as figure 1 As shown, the existing fully automatic pulsator washing machine generally includes a pulsator 1', an inner tub 2', an outer tub 3' and a cabinet 4' arranged sequentially from the inside to the outside, wherein the pulsator 1' is arranged in the inner tub 2 'The center of the bottom can be rotated by the driving device 5'. ...

AI Technical Summary

Problems solved by technology

[0010] Although the above-mentioned comparative patent can reduce the amount of washing water to a certain extent, when the inner tub rotates at high speed to perform the washing procedure, the washing liquid and the clothes rotate together under the action of the centrifugal force generated by the inner tub, during which the clothes are kept in the air along with the washing liquid. Rotating at a relatively fixed vertical height, the friction between the clothes and the washing liquid, the clothes and the inner tub is relatively limited, and the washing degree of the clothes is not high

[0011] In addition, the drainage pipeline of the washing machine is a double-layer structure with an inner bucket for drainage. It can only be drained by intermittent drainage with multiple cycles of turn-stop-turn-stop, so that water can be discharged from the drain hole at the bottom of the barrel.
