Washing machine dehydration control method and washing machine

Abstract

The invention discloses a dehydration control method for a washing machine and a washing machine. The method controls an inner barrel / drum through a motor to sequentially perform two-stage control, firstly performing low-speed intermittent dehydration and then performing high-speed intermittent dehydration. In the low-speed intermittent dehydration stage, forward low-speed dehydration and reverse low-speed dehydration are sequentially performed at a rotation speed lower than a first set rotation speed, and after the forward low-speed dehydration and reverse low-speed dehydration, the first set time is stopped. Through low-speed forward rotation and low-speed reverse rotation, clothes are scattered and laid flat, so that the clothes can be closely attached to the inner barrel / drum wall in a manner of being laid as flat as possible in the high-speed intermittent dehydration stage, thereby reducing the generation of wrinkles. In the high-speed intermittent dehydration stage, forward high-speed dehydration and reverse high-speed dehydration are sequentially performed at a rotation speed higher than a second set rotation speed, and after the forward high-speed dehydration and reverse high-speed dehydration, inertia dehydration is performed to prevent the clothes from being squeezed into blocks due to long-term dehydration in the same direction, thereby further reducing the degree of wrinkles on the clothes.

Description

Technical Field

[0001] The present 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 Art

[0002] In the existing washing machines, the washing tub assembly is generally rotated to drive the clothes to move so as to wash the clothes. After washing, the washing tub assembly is rotated to drive the clothes to move so as to dehydrate the clothes.

[0003] When the washing tub assembly dehydrates the clothes by rotating, the inner tub / drum rotates at high speed, and the clothes are tightly attached to the inner tub / inner tub wall under the action of centrifugal force. As the rotation process progresses, water is squeezed out of the clothes from the inside to the outside and discharged from the inner tub / drum. As the dehydration speed increases, the wrinkles caused by the squeezing become more severe and form lumps. When the clothes are taken out, they will clump or stick together, causing user complaints. Moreover, the wrinkles formed during the dehydration period are difficult to eliminate, and users must iron the clothes before wearing them, which is bound to increase user complaints and reduce the user experience. Summary of the invention

[0029] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0030] The present invention aims to reduce the wrinkles on clothes caused during dehydration by a dehydration control method that starts at a low speed and then at a high speed, combined with alternating forward and reverse directions. The present invention can be applied to pulsator washing machines as well as drum washing machines, and is achieved by controlling the rotation of the inner barrel / drum through a motor.

[0031] Specifically, Figure 1 As shown, the washing machine dehydration control method includes two stages of control performed sequentially:

[0032] Step S1, low-speed intermittent dehydration stage;

[0033] In this stage, the forward low-speed spin-drying and the reverse low-speed spin-drying are performed in sequence at a rotation speed lower than the first set rotation speed, and the forward low-speed spin-drying and the reverse low-speed spin-drying are stopped for the first set time after each of the two processes.

[0034] That is, the inner barrel / drum is first driven at a speed VL lower than the first set speed V1 to perform low-speed dehydration in the forward direction, where the forward direction is, for example, clockwise rotation; after the forward low-speed dehydration, it stops for the first set time, and then the inner barrel / drum is driven at a speed VL lower than the first set speed V1 to perform low-speed dehydration in the reverse direction, where the reverse direction is relative to the above-mentioned forward direction. When the forward direction is clockwise, the reverse direction is counterclockwise, and when the forward direction is counterclockwise, the reverse direction is clockwise; after the reverse low-speed dehydration, it stops for the first set time.

[0035] Step S2, high-speed intermittent dehydration stage;

[0036] In this stage, forward high-speed spin-drying and reverse high-speed spin-drying are sequentially performed at a rotation speed higher than the second set rotation speed, and inertia spin-drying is performed after both the forward high-speed spin-drying and the reverse high-speed spin-drying.

[0037] That is, the inner tub / drum is first driven at a speed VH higher than the second set speed V2 to perform high-speed dehydration in the forward direction, and then stops for the second set time after the forward high-speed dehydration. Then, the inner tub / drum is driven at a speed VH higher than the second set speed V2 to perform high-speed dehydration in the reverse direction, and then stops for the first set time after the reverse high-speed dehydration.

[0038] The first set rotation speed V1 here is smaller than the second set rotation speed V2.

[0039] Based on the washing machine dehydration control method proposed by the present invention, the clothes can be scattered and laid flat by low-speed forward rotation and low-speed reverse rotation in the low-speed intermittent dehydration stage, so that the clothes can be laid as flat as possible on the inner barrel / barrel wall in the high-speed intermittent dehydration stage, thereby reducing the generation of wrinkles; in the low-speed intermittent dehydration stage and the high-speed intermittent dehydration stage, the clothes are dehydrated in both forward and reverse directions at intervals, which can prevent the clothes from being squeezed into blocks due to long-term dehydration in the same direction, thereby further reducing the degree of wrinkles on the clothes, and solving the technical problem of clothes wrinkles caused by dehydration in existing washing machines.

[0040] The washing machine dehydration control method proposed by the present invention is described in detail with reference to several specific embodiments.

[0041] Embodiment 1: Applicable after the washing stage is completed

[0044] After the washing process is completed, the detergent, foam, etc. in the clothes are discharged through dehydration to facilitate a more thorough rinsing stage.

[0045] 2. The inner drum / 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 set duration for stopping after forward and reverse rotation is 5 seconds.

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

[0047] b. Stop for 5 seconds;

[0048] c. Drive the inner barrel / drum to rotate counterclockwise at low VL1 for 10 seconds;

[0049] d. Stop for 5 seconds.

[0050] Spin clothes flat by spinning at low speed in forward and reverse directions to prevent wrinkles during subsequent high-speed spinning.

[0071] g. Rotate the inner barrel / drum in a counterclockwise direction at high speed VH1 for 30 seconds;

[0072] h. Inertial dehydration until it stops.

[0073] High-speed rotation is used to achieve efficient dehydration, and alternating forward and reverse directions is used to avoid squeezing of clothes due to long dehydration time in the same direction, which would cause wrinkles.

[0074] Through the above-mentioned dehydration control, the detergent and foam remaining in the clothes after a rinsing process is completed can be discharged, and wrinkles on the clothes can be avoided during dehydration.

[0083] d. Stop for 5 seconds;

[0084] e. Repeat steps a to d for a first set number of times. In this embodiment, the first set number of times is 3 times.

[0085] By spinning the clothes in forward and reverse directions at a low speed and repeating the first set number of times, the clothes can be fully loosened and flattened to prevent wrinkles during the subsequent high-speed spin cycle.

[0086] 3. The inner barrel / drum is controlled by the motor to enter the high-speed intermittent dehydration stage; wherein, the forward and reverse rotation durations are both the third set duration of 50 seconds.
