Problems solved by technology

But at this time, the clothes are evenly distributed in the inner bucket, and the evenly distributed clothes naturally form a filter screen when draining. Increasing spray rinsing can only reduce foam, and has little effect on washing lint and dirt

specific Embodiment approach 1

[0033] Embodiment 1: During the drainage process, the redistribution stage is executed, the inner tub 3 is controlled to run in one direction at the first rotational speed, and the spraying stage is executed after the drainage is completed. like figure 2As shown in the control flow chart, the redistribution stage is as follows: after washing, the drain valve is opened, the washing machine starts to drain water, and at the same time, the inner tub 3 is controlled to run in one direction at a first rotational speed, and the first rotational speed can be determined according to The weight of the load in the inner tub 3 is used for setting, and the first rotational speed is proportional to the weight of the load in the inner tub 3 . The load in the inner barrel 3 is separated from the center of the inner barrel 3 within the size of the first rotational speed, and the center of the inner barrel 3 forms a cavity preferably. Loads with different weights correspond to different firs...

specific Embodiment approach 2

[0036] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: before performing the redistribution stage, it also includes: controlling the inner bucket 3 to run in one direction or two directions at the second speed during the drainage process, when detecting the drainage in the inner bucket 3 When the preset displacement is reached, the second speed running state ends, such as figure 2 The control flow diagram shown. The size of the second rotating speed should be such that the water in the inner tub 3 can be slowly thrown out from the dehydration hole 31 above, and the second rotating speed is set according to the height of the water level in the inner tub 3 . The first rotating speed is inversely proportional to the height of the water level in the inner tub 3 . The rotation speed corresponding to each water level is recorded in the controller, the rotation speed range is 200-400 rpm, and the second rotation speed is greater than or e...

specific Embodiment approach 3

[0039] Embodiment 3: After the drainage is completed, the redistribution stage is executed, and the inner tub is controlled to run in one direction at the third rotational speed. After the inner tub 3 runs for the first predetermined time, the spraying stage is executed. like image 3 The control flow chart shown is specifically: after the washing is finished, the drain valve is opened, and when the water level detection device detects that the current water level is less than or equal to the minimum water level, it is considered that the water in the inner tub 3 has been drained. The minimum water level is used to judge whether there is water in the inner bucket 3, and the minimum water level is stored in the controller, preferably 0≤minimum water level<5mm. Since the inner tub 3 is not running during the drainage process, no cavity is formed in the inner tub 3. Therefore, after the drainage is completed, it is necessary to control the inner tub 3 to run at a third speed so t...

Abstract

The invention belongs to the field of clothing treatment equipment, and particularly discloses a control method of a washing machine. After a washing program is finished, an inner barrel is controlledto execute a redistribution stage and a spray stage sequentially, the load redistribution stage is to control the inner barrel to redistribute the load in the drainage process and / or after the drainage process, and the spray stage is to control the inner barrel to operate and to be sprayed after the redistribution stage is finished. According to the control method, the inner barrel is controlledto operate unidirectionally at a certain speed to form a cavity in the inner barrel during or after the drainage, then the inner barrel is controlled to operate at a low speed and is sprayed, the yarnchips on the load surface are washed away and flow out of the inner barrel from the cavity, and thus the purpose of removing the yarn chips is achieved.

Description

technical field [0001] The invention belongs to the field of clothes processing equipment, and in particular relates to a washing machine control method and the washing machine. Background technique [0002] When the washing machine is washing clothes, some lint, dirt and foam tend to float above the water. And because there is no water between the barrels / no outer barrel and other non-porous inner barrel washing machines, the inner barrel does not have dehydration holes 31 in structure. When draining, all the water is discharged from the bottom, and the evenly distributed clothes naturally form a filter when draining. The lint, dirt and foam floating above the water are isolated by the clothes above the clothes. Therefore, it is more difficult for these lint, dirt and foam to be discharged, and the problem of lint adhesion is easy to appear on the clothes after washing. The existing practice is to increase the spray rinse after washing. But at this time, the clothes are ...
