Embodiment 1

[0041] Embodiment 1, suitable for after the washing stage

[0042] Specific as figure 2 Shown:

[0043] 1. The dehydration command is received after the washing program is finished.

[0044] After the washing process is over, the detergent and foam in the clothes are discharged by dehydration, so that the rinsing stage can be rinsed more thoroughly.

[0045] 2. The inner barrel / drum is controlled by the motor to enter the low-speed intermittent dehydration stage; the second setting time is 10 seconds for forward and reverse rotation; the first setting time for stopping after forward rotation and reverse rotation is 5 seconds.

[0046] a. Drive the inner barrel / barrel to rotate clockwise at low speed VL1 for 10 seconds;

[0047] b. Stop for 5 seconds;

[0048]c. Drive the inner barrel / barrel to rotate for 10 seconds in the counterclockwise direction according to the low level VL1;

[0049] d. Stop for 5 seconds.

[0050] Spin in forward and reverse directions at low spee...

Embodiment 3

[0075] Embodiment 3, suitable for the dehydration stage of the washing machine

[0076] Specific as Figure 4 Shown:

[0077] 1. After the washing program and rinsing program are finished, the dehydration command is received.

[0078] This embodiment is applicable to the dehydration control of the washing machine after washing and rinsing.

[0079] 2. The inner barrel / drum is controlled by the motor to enter the low-speed intermittent dehydration stage; the forward and reverse rotation durations are both the second set duration of 10 seconds; the first preset duration of forward and reverse rotation and stop is 5 seconds.

[0080] a. Drive the inner barrel / barrel to rotate clockwise at low speed VL1 for 10 seconds;

[0081] b. Stop for 5 seconds;

[0082] c. Drive the inner barrel / barrel to rotate for 10 seconds in the counterclockwise direction according to the low level VL1;

[0083] d. Stop for 5 seconds;

[0084] e. Repeat step a to step d for the first set number of...

Abstract

The invention discloses a washing machine dewatering control method and washing machine. The washing machine dewatering control method is characterized in that an inner barrel/drum is controlled by a motor to sequentially execute control of two stages, namely low-speed intermittent dehydration and high-speed intermittent dehydration in sequence, wherein in the low-speed intermittent dehydration stage, forward low-speed dehydration and reverse low-speed dehydration are sequentially executed at a rotating speed lower than a first set rotating speed; the first set duration is stopped after the forward low-speed dehydration and the reverse low-speed dehydration, and the clothes are scattered and laid in a low-speed forward rotation mode and a low-speed reverse rotation mode, so that the clothes can be tightly attached to the inner barrel/barrel wall in the mode that the clothes are laid as much as possible in the high-speed intermittent dehydration stage, and therefore wrinkles are reduced; in the high-speed intermittent dehydration stage, forward high-speed dehydration and reverse high-speed dehydration are sequentially executed at the rotating speed higher than a second set rotating speed; and inertial dehydration is executed after forward high-speed dehydration and reverse high-speed dehydration, so that the situation that clothes are extruded into blocks due to long-time dehydration in the same direction is prevented, and the wrinkle degree of the clothes is further reduced.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine dehydration control method and a washing machine. Background technique [0002] Existing washing machines generally realize the washing of clothes through the rotation of the washing tub assembly to drive the movement of the clothes. After the washing is completed, the dehydration of the clothes is realized by driving the movement of the clothes through the rotation of the washing tub assembly. [0003] When the washing tub assembly dehydrates the clothes by rotating, the inner tub / tub rotates at a high speed, and the clothes cling to the wall of the inner tub / tub under the action of centrifugal force, and squeeze the water from the clothes from the inside to the outside during the rotation process. Squeeze out and discharge the inner tub / tube, and with the increase of dehydration speed, the squeeze will cause wrinkles to increase and form l...
