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

Embodiment 1

[0041] Such as Figure 2 to Figure 4 As shown, the fully automatic washing machine of the present invention includes a casing 1, an outer tub 2 arranged in the casing 1, an inner tub 3 arranged in the outer tub 2 and a pulsator 4 arranged in the inner tub 3, wherein the outer The barrel 2 is connected to the casing 1 of the washing machine through a plurality of suspension rods 5, and the lower part of the outer barrel 2 is provided with a driving device 6 for driving the rotation of the inner barrel 3 and the pulsator 4; , generally located in the area above the height of 5 / 6 of the inner barrel body 32, preferably the dehydration hole 31 is located in the area above the height of 9 / 10 of the inner barrel body 32, so that when washing, the agitated water flow cannot pass through the dehydration hole 31 Drain, the top opening of the inner barrel 3 is provided with a balance ring 33, the dehydration hole 31 is located below the balance ring 33, the inner barrel body 32 peripher...

Embodiment 2

[0046] The drainage control method of the washing machine of the present invention controls the rotating speed of the inner tub in stages by detecting the variation of the remaining water in the inner tub.

[0047] The drain outlet 8 or drain pipeline 9 of the washing machine outer tub of the present invention is provided with a drain flow sensor 70, and the drain flow sensor 70 is used to measure the water volume discharged from the washing machine, and the remaining water volume in the inner tub is calculated by subtracting the drained water volume from the water intake of the washing machine. Alternatively, the remaining water in the inner bucket is detected by a load cell.

[0048] Specifically, as Figure 5 As shown, the control of the speed of the inner tub during the drainage process includes three stages, and each stage is a speed-up stage. Before the drainage starts, the water inflow in the washing machine is M0, and the speed of the inner tub is controlled from 0 to ...

Embodiment 3

[0053] Another washing machine drainage control method of the present invention controls the rotation speed of the inner tub in stages according to the drainage time. The longer the drainage time is, the higher the rotation speed of the inner tub is controlled in the next stage.

[0054] Such as Figure 6 As shown, the control of the speed of the inner barrel during the drainage process includes four stages, each stage is a speed-up stage. During the drainage, the speed of the inner barrel is controlled from 0 to the set speed V1. The time used for this process is T1, and then the speed V1 is maintained. When When running for the set time T2-T1, enter the second stage, increase the speed of the inner barrel to V2, the use time of this speed-up stage is T3-T2, and then maintain the speed V2 to run the set time T4-T3, enter the third stage, increase the inner barrel When the speed reaches V3, the use time of this speed-up stage is T5-T4, and then maintain the speed V3 to run for...

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'. ...
