Problems solved by technology

[0004] Judging from the current improvement methods, when the clothes are slightly entangled, the existing structural and procedural methods can effectively eliminate the entanglement problem, but in the state of water, some clothes are only intertwined and not too entangled. Tight, in this state it is easier to untangle, if you drain the water directly and start dehydration at this time, the winding may be intensified under the action of gravity and centrifugal force, resulting in eccentricity, which will cause the dehydration to fail to proceed normally

Embodiment 1

[0038] In a specific embodiment of the present invention, controlling the forward rotation and / or reverse rotation and / or forward and reverse rotation of the washing tub may specifically be the following method: during the drainage process, control the washing tub to rotate in the forward direction until the drainage ends; Or control the washing tub to rotate in the opposite direction to the end of the drainage during the drainage process; or control the washing tub to rotate in the forward and reverse direction alternately to the end of the drainage during the drainage process.

[0039] In the above technical solution of this embodiment, controlling the rotation direction of the washing tub can quickly complete the drainage process and save drainage time.

Embodiment 2

[0041] Such as figure 1 As shown, in a specific embodiment of the present invention, the liquid level in the washing tub is preset to N calibration values, which are respectively the preset liquid level W 1 , W 2 and W 3 , where W 1 >W 2 >W 3 , in order to facilitate the description of the technical solution of the present invention, this embodiment only lists three liquid level values, which can be set by those skilled in the art according to the actual situation, and no specific limitation is made here; the preset value is the same as the above liquid level W 1 Corresponding speed V 1 , preset with the above liquid level W 2 Corresponding speed V2 , preset with the above liquid level W 3 Corresponding speed V 3 , where V 1 2 3 , to obtain the actual liquid level H in the washing tub, when the obtained actual liquid level H is less than the preset minimum liquid level W among the preset N calibration values 3 At this time, the washing machine controls the drain valv...

Embodiment 3

[0043] In a specific embodiment of the present invention, the liquid level in the washing tub is preset to two calibration values, namely the preset maximum liquid level and the preset minimum liquid level, and the actual liquid level in the washing tub is obtained when drainage starts H, when the obtained actual liquid level H is less than or equal to the preset maximum liquid level and greater than the preset minimum liquid level, that is, the liquid level between the preset maximum liquid level and the preset minimum liquid level, the washing machine controls the drain valve to open, Control the washing tub to run at a preset speed corresponding to the preset liquid level; and during the drainage process, when it is judged that the liquid level in the washing tub is gradually decreasing, the rotating speed of the washing tub is controlled to gradually increase, so that the washing tub The rotating speed can be continuously increased as the liquid level in the washing bucket ...

Abstract

The invention discloses a drainage control method of a washing machine and the washing machine adopting the same. The control method comprises the step that in a drainage process, the washing machine controls a washing barrel to rotate. According to the drainage control method provided by the invention, an anti-winding control method of the drainage process is added on the basis of controlling a time sequence before dewatering; and the method specifically comprises the step that in the drainage process, the rotating direction and the rotating speed of the washing barrel are controlled, so that loads in water can be distributed towards the edge of an inner barrel under the action of centrifugal force, clothes winding in a washing or rinsing process can be effectively reduced, the eccentricity of the washing barrel due to clothes winding after drainage is reduced, and the purposes of saving water, electricity and time are achieved.

Description

technical field [0001] The invention belongs to the technical field of laundry equipment, and in particular relates to a washing machine drainage control method and the washing machine. Background technique [0002] During the rinsing process of the wave wheel washing machine, the rinsing water will be discharged first and then the dehydration process of rinsing will start. If serious clothes entanglement occurs during the washing process, the method of direct drainage and then dehydration is adopted. The state of entanglement of clothes will always exist, resulting in uneven distribution of clothes in the inner tub. In this case, dehydration will cause large The eccentricity of the washing machine will cause the rinsing and dehydration to be unable to proceed normally, and the washing machine will automatically add one more rinsing for correction, and the extra rinsing will cause a lot of waste of water and electricity resources. [0003] At present, the anti-winding of mo...
