A washing machine is a cleaning appliance that washes laundry using mechanical action generated by electric energy. In the washing process, if a user puts in excessive washing powder or uses high-foam washing powder, or the clothes put into the washing bucket/drum are excessive, a large amount of foam is generated between the inner bucket/drum and the outer bucket/drum of the washing machine, so that the motor cannot reach the highest rotating speed in the dehydration process, and the normal operation of the dehydration is influenced. In view of the above problems, the present invention provides a dehydration control method of a washing machine.

Fig. 1 is a flowchart illustrating a dehydration control method of a washing machine according to the present invention. The dehydration control method of the washing machine of fig. 1 may be performed by the server, may also be performed by the washing machine, or may also be performed by both the server and the washing machine. As shown in fig. 1, the dehydration control method of the washing machine includes:

s101, controlling a motor of the washing machine to operate for a first preset time, and continuously controlling the motor to operate for a second preset time after the motor operates for the first preset time;

s102, acquiring a first rotating speed of the motor after the motor runs for a second preset time;

s103, controlling the motor to run for a third preset time under the condition that the first rotating speed is greater than or equal to the first rotating speed threshold;

s104, after the motor runs for a third preset time, acquiring a second rotating speed of the motor;

and S105, controlling the washing machine to execute the dehydration program under the condition that the second rotating speed is greater than or equal to the second rotating speed threshold value.

Specifically, taking a washing machine as an example, when a user needs the washing machine to execute a dehydration program, a controller (or a processor) of the washing machine controls a motor to accelerate from a standstill and operate for a first preset time, after the motor operates for the first preset time, the controller continues to control the motor to operate for a second preset time, and after the motor operates for the second preset time, a first rotating speed of the motor is acquired; further, the controller compares the acquired first rotating speed with a first rotating speed threshold value to determine whether the first rotating speed is greater than or equal to the first rotating speed threshold value; when the first rotating speed is greater than or equal to the first rotating speed threshold value, the controller controls the motor to operate for a third preset time, and a second rotating speed of the motor is obtained after the motor operates for the third preset time; the controller compares the acquired second rotating speed of the motor with a second rotating speed threshold value to determine whether the second rotating speed is greater than or equal to the second rotating speed threshold value; when the second rotation speed is greater than or equal to the second rotation speed threshold, the controller controls the washing machine to perform a dehydration process.

Here, the server may be a server that provides various services, for example, a backend server that receives a request transmitted by a terminal device with which a communication connection is established, and the backend server may perform processing such as receiving and analyzing the request transmitted by the terminal device and generate a processing result. The server may be one server, or a server cluster composed of a plurality of servers, or may also be a cloud computing service center, which is not limited in this embodiment of the present invention.

The server may be hardware or software. When the server is hardware, it may be various electronic devices that provide various services to the terminal device. When the server is software, it may be multiple software or software modules providing various services for the terminal device, or may be a single software or software module providing various services for the terminal device, which is not limited in this embodiment of the present invention.

The terminal device may be hardware or software. When the terminal device is hardware, it may be various electronic devices having a display screen and supporting communication with the server, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like; when the terminal device is software, it may be installed in the electronic device as described above. The terminal device may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module, which is not limited in this embodiment of the present invention.

The first preset time, the second preset time and the third preset time refer to preset operation time of the motor. The first preset time, the second preset time, and the third preset time may be preset times according to empirical data, or may be obtained by adjusting the set times according to actual needs, which is not limited in this embodiment of the present invention. Further, the third preset time may be greater than the second preset time and less than or equal to the first preset time. For example, the first preset time may be in the range of 1 minute to 2 minutes, the second preset time may be in the range of 10 seconds to 30 seconds, and the third preset time may be in the range of 30 seconds to 60 seconds. Preferably, in the embodiment of the present invention, the first preset time is 2 minutes, the second preset time is 30 seconds, and the third preset time is 60 seconds.

The first rotating speed is the rotating speed reached after the motor operates for the second preset time from the standstill, and the second rotating speed is the rotating speed reached after the motor operates for the third preset time on the basis of the first rotating speed; further, the first rotational speed is less than the second rotational speed.

The first rotating speed threshold value refers to the lowest rotating speed required to be reached by the motor after the motor operates for the first preset time and the second preset time. The first rotation speed threshold may be a rotation speed threshold preset according to empirical data, or may be a rotation speed threshold obtained by adjusting a set rotation speed threshold according to actual needs, which is not limited in this embodiment of the present invention. For example, the first speed threshold may be in the range of 300rpm to 400rpm, where rpm is an abbreviation for Revoltations Per Minute, i.e., Revolutions Per Minute, representing the number of Revolutions Per Minute of the device. Preferably, in an embodiment of the present invention, the first rotation speed threshold is 350 rpm.

The second rotation speed threshold refers to the minimum rotation speed required to be reached by the motor after the motor operates for the first preset time, the second preset time and the third preset time. The second rotation speed threshold may be a rotation speed threshold set according to empirical data, or may be a rotation speed threshold obtained by adjusting the set rotation speed threshold according to actual needs, which is not limited in this embodiment of the present invention. For example, the second rotational speed threshold may be in the range of 400rpm to 500 rpm. Preferably, in the embodiment of the present invention, the second rotation speed threshold is 450 rpm.

It should be understood that after the operation is started from the standstill for the first preset time, the rotating speed of the motor can be increased and gradually tends to be stable, and at this time, the first rotating speed of the motor is obtained, and whether the foam is excessive or not is judged based on the first rotating speed, so that the accuracy of the foam detection can be improved.

It should be noted that the embodiment of the present invention is not limited to the washing machine, and may be a shoe washing machine, a washing and drying machine, etc.

According to the technical scheme provided by the embodiment of the invention, the motor of the washing machine is controlled to operate for the first preset time, and after the motor operates for the first preset time, the motor is continuously controlled to operate for the second preset time; after the motor runs for a second preset time, acquiring a first rotating speed of the motor; controlling the motor to run for a third preset time under the condition that the first rotating speed is greater than or equal to the first rotating speed threshold value; after the motor runs for a third preset time, acquiring a second rotating speed of the motor; under the condition that the second rotating speed is greater than or equal to the second rotating speed threshold value, the washing machine is controlled to execute the dewatering program, and foam in washing water in the washing machine can be reduced, so that the blockage of the foam to the rotation of the motor is avoided, the probability of the motor stalling is reduced, the motor is protected, the flexibility of control during dewatering is improved, and the user experience is further improved.

Specifically, if the acquired first rotating speed is less than the first rotating speed threshold value, it indicates that a large amount of foam exists in the inner tub/drum of the washing machine, and at this time, the controller controls the motor to temporarily stop running for a fourth preset time, so that the foam in the inner tub/drum can naturally fall to the bottom of the tub/drum under the action of gravity; after the motor stops running for the fourth preset time temporarily, the controller controls the motor to run for the first preset time again.

Here, the fourth preset time refers to a time when the motor is suspended, and the fourth preset time is greater than the first preset time. During the fourth preset time when the motor is in pause, the foam in the inner tub/drum of the washing machine can automatically fall to the bottom of the tub/drum through the action of gravity, or the foam in the inner tub/drum of the washing machine is fused with the moisture on the clothes to be dehydrated, so that the foam in the inner tub/drum is reduced.

Specifically, if the acquired second rotating speed is less than the second rotating speed threshold value, it indicates that a large amount of foam still exists in the inner tub/drum of the washing machine, and at this time, the controller controls the motor to temporarily stop running for a fourth preset time, so that the foam in the inner tub/drum can naturally fall to the bottom of the tub/drum under the action of gravity; after the motor stops running for the fourth preset time temporarily, the controller controls the motor to run for the first preset time again.

Specifically, if the acquired first rotation speed is less than the first rotation speed threshold value, it indicates that a large amount of foam exists in the inner tub/drum of the washing machine, at this time, the controller controls the washing machine to perform a defoaming procedure, and after the defoaming procedure is completed, the controller controls the motor to operate again for a first preset time.

Here, the defoaming procedure may be stopping the operation of the washing drum to prevent more foam from being generated, and opening the drain pump to discharge the foam through the drain pump after the foam naturally settles down; or the foam can be washed by spraying water into the washing cylinder, and then the drainage pump is opened to discharge the foam; or hot air can be blown into the washing drum through the drying system so as to blow off the foam in the drum through the hot air.

Specifically, if the acquired second rotating speed is less than the second rotating speed threshold value, it indicates that a large amount of foam still exists in the inner tub/drum of the washing machine, at this time, the controller controls the washing machine to execute the defoaming program, and after the defoaming program is completed, the controller controls the motor to operate again for the first preset time.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.

The dehydration control method of the washing machine of fig. 2 may be performed by the server, may also be performed by the washing machine, or may also be performed by both the server and the washing machine. As shown in fig. 2, the dehydration control method of the washing machine includes:

s201, controlling a motor of the washing machine to operate for a first preset time, and continuing to control the motor to operate for a second preset time after the motor operates for the first preset time;

s202, after the motor runs for a second preset time, acquiring a first rotating speed of the motor;

s203, determining whether the first rotating speed is greater than or equal to a first rotating speed threshold value, and if so, executing S204; otherwise, executing S207;

s204, controlling the motor to operate for a third preset time, and acquiring a second rotating speed of the motor after the motor operates for the third preset time;

s205, determining whether the second rotating speed is greater than or equal to a second rotating speed threshold value, and if so, executing S206; otherwise, executing S207;

s206, controlling the washing machine to execute a dehydration program;

and S207, controlling the motor to stop running for a fourth preset time, or controlling the washing machine to execute a defoaming program, and returning to execute S201.

According to the technical scheme provided by the embodiment of the invention, the rotating speed of the motor after running for a certain time is obtained, the obtained rotating speed is compared with the rotating speed threshold value to judge whether a large amount of foam exists in the washing machine, and a certain defoaming measure is taken under the condition that the large amount of foam exists in the washing machine, so that the foam in the washing water in the washing machine can be reduced, the obstruction of the foam to the rotation of the motor is avoided, the stopping probability of the motor is reduced, the motor is protected, the control flexibility during dehydration is improved, and the user experience is further improved.
