Problems solved by technology

[0003] However, after the washing machine is used for a long time, the connection between the motor adapter and the washing tub may become loose. At this time, the motor adjusts the motor speed after receiving the speed control command, but due to the loose connection between the motor adapter and the washing tub, causing The rotation speed of the motor adapter and the washing tub is not synchronized, and the load of the motor fluctuates greatly, which is very easy to cause the washing machine to spin and damage the washing machine. Therefore, there is an urgent need for an effective method to control the washing machine motor. It is very important to ensure the normal and stable operation of the motor.

Embodiment 1

[0021] Such as figure 1 As shown, a motor control method according to an embodiment of the present invention includes the following steps:

[0022] S1: After the washing machine is started, a first rotational speed control command is sent to the motor, and the first rotational speed control command includes a first rotational speed acceleration;

[0023] S2: The motor accelerates at the first speed acceleration;

[0024] S3: When the motor is accelerating at the first speed acceleration, acquire the speed of the motor at the first moment and the speed of the washing tub at the first moment;

[0025] S4: judging whether the rotation speed of the motor at the first moment is the same as the rotation speed of the washing tub at the first moment;

[0026] If so, the washing machine continues to run at the first rotational speed acceleration;

[0027] If not, go to the next step;

[0028] S5: Sending a motor stop rotation instruction to the motor, controlling the motor to stop ...

Embodiment 2

[0031] An embodiment of the present invention provides a washing machine, which includes a washing tub; a motor; a memory; a processor; and a computer program;

[0032] Wherein, the computer program is stored in the memory, and is configured to execute the motor control method described in Embodiment 1 by the processor, so as to control the motor to accelerate the speed.

Embodiment 3

[0034] An embodiment of the present invention provides a storage medium readable by an electronic device, the storage medium readable by an electronic device may store a program, and when the program is run on the electronic device, the electronic device executes the method described in Embodiment 1.

Abstract

The invention discloses a motor control method and a washing machine. The motor control method comprises the following steps: after the washing machine is started, sending a first rotation speed control instruction to a motor, wherein the first rotation speed control instruction comprises a first rotation speed acceleration; when the motor carries out rotation speed acceleration at the first rotation speed acceleration, acquiring a rotation speed of the motor at a first moment and a rotation speed of a washing bucket at the first moment; judging whether the rotation speed of the motor at the first moment is the same as the rotation speed of the washing bucket at the first moment; if so, enabling the washing machine to operate at the first rotation speed acceleration; otherwise, executing the next step; and sending a motor rotation stop instruction to the motor and controlling the motor to stop rotating so as to enable the washing bucket to stop rotating. According to the motor controlmethod and the washing machine disclosed by the invention, the defects in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a motor control method and a washing machine. Background technique [0002] At present, the motor and the washing tub are the key components in the washing machine. A motor adapter is connected between the motor and the washing tub. When the washing machine is in normal operation, the motor drives the motor adapter to rotate, and then drives the washing tub. Spin to wash clothes. [0003] However, after the washing machine is used for a long time, the connection between the motor adapter and the washing tub may become loose. At this time, the motor adjusts the motor speed after receiving the speed control command, but due to the loose connection between the motor adapter and the washing tub, the The speed of the motor adapter is not synchronized with that of the washing tub, and the load of the motor fluctuates greatly, causing the washing machine to spin and damage the...
