Problems solved by technology

[0002] At present, the capacity of the washing machine is getting larger and larger, and the types of fabrics to be washed are increasing, so when the user stuffs too much laundry in use, it may appear It is easier to trap clothes and cause a load, especially small clothes such as handkerchiefs or towels or baby clothes; once the above clothes are caught, the washing machine will not operate normally
[0003]Therefore, it is necessary to propose a washing machine control method, which can solve the problem that the phenomenon of cloth clamping in the prior art cannot be effectively solved, and the problem can only be stopped by waiting for the user to take out the clothes

Embodiment 1

[0035] figure 1 It is a flow chart of a washing machine control method provided by Embodiment 1 of the present invention. The washing machine control method provided in this embodiment is used to implement a scenario where the washing machine executes dehydration stages of various programs. The washing machine control method provided in this embodiment can be executed by the main control board of the washing machine, and the main control board can be realized by software and integrated in the washing machine. The washing machine control method provided in this embodiment may be automatically executed after the user puts in the laundry and presses the start button after the washing machine is powered on.

[0036] The washing machine control method provided in this embodiment specifically includes: during the process of gradually increasing the dehydration speed, regularly detect the motor torque and judge whether the motor torque is abnormal; Increase the speed for dehydratio...

Embodiment 2

[0046] In this embodiment, the washing machine control method provided in this embodiment can be automatically executed after the start button of the washing machine is triggered. The washing machine control method provided in this embodiment specifically includes: during the process of gradually increasing the speed of dehydration, regularly detecting the motor torque and judging whether the motor torque is abnormal; Reach the first preset number of times, if not, stop the dehydration and increase the speed and reverse, and then increase the speed again to perform the dehydration operation. If reached, the washing machine stops working and reports to the police.

[0047] In this embodiment, the determination of the number of startup dehydration speed-ups in the current program is added, which can prevent the washing machine from reversing for an unlimited number of times and falling into an endless loop.

[0048] The first preset number of times N can be obtained based on em...

Embodiment 3

[0062] Since the washing machine mostly washes the clothes in one washing and two rinsing modes, the washing machine can stop working after three dehydration tasks are completed. After the washing machine completes the dehydration task, it is also necessary to judge whether the number of times of water inflow and rinsing reaches the second preset number of times. If it reaches the second preset number of times, the washing machine stops working. If not, the washing machine enters water for rinsing. Wherein, the number of rinsing times can be automatically selected by the washing machine; of course, the user can also manually choose to increase the number of rinsing times. In this embodiment, the number of times of rinsing is the second preset number, which should be greater than or equal to 2.

[0063] After the washing machine continues to perform the dehydration task, it is necessary to determine whether the number of water-intake rinsing reaches the second preset number of t...

Abstract

The invention relates to the technical field of household appliance control, in particular to a control method of a washing machine and the washing machine. According to the method, in the process ofgradual acceleration for dewatering, the motor torque is detected regularly and whether the motor torque is abnormal or not is judged; under the abnormal condition, acceleration for dewatering is stopped and reverse rotation is performed; then, acceleration is performed again for dewatering operation. By use of the control method of the washing machine, the torque of the washing machine can be detected automatically, the cloth clamp problem of the washing machine can be judged according to increase of the torque of the washing machine, meanwhile, the washing machine can be controlled to rotatereversely and rotate out clamped cloth from a washing machine window pad, the trouble of cloth clamping is effectively solved, and satisfaction of a user can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliance control, in particular to a washing machine control method and the washing machine. Background technique [0002] At present, the capacity of washing machines is getting bigger and bigger, and there are more and more types of fabrics to wash. In this way, when users stuff in too much laundry, it may be easier to pinch the clothes and cause a load, especially for small pieces of clothes. , such as handkerchiefs or towels or baby clothes; once the above clothes get caught, the washing machine will not work properly. [0003] Therefore, it is necessary to propose a washing machine control method, which can solve the problem that the cloth clamping phenomenon in the prior art cannot be effectively solved, and the washing machine can only be shut down to wait for the user to take out the clothes. Contents of the invention [0004] The purpose of the present invention is to propose a wash...
