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

[0022] like figure 1 As shown, a motor control method according to an embodiment of the present invention includes the following steps:

[0023] S1: Start the washing machine, send a first rotational speed control command to the motor so that the motor rotates according to the first rotational speed control command within the 0-T detection time, the first rotational speed control command includes a first rotational speed acceleration, and the first rotational speed control command - speed acceleration is positive acceleration;

[0024] S2: Obtain the highest rotational speed of the washing tub within the 0-T detection time;

[0025] S3: judging whether the maximum rotation speed of the washing tub within the time period of 0-T is within the reference range of the preset maximum rotation speed, the preset maximum rotation speed is the theoretical maximum rotation speed after the motor accelerates at the first rotation speed for a time T;

[0026] If not, execute step S4;

[...

Embodiment 2

[0032] 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;

[0033] 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

[0035] 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 steps: S1, starting the washing machine and transmitting a first rotating speed control instruction to a motor so as to enable the motor to rotate according to the first rotating speed control instruction in 0-T detection time, wherein the first rotating speed control instruction comprisesfirst rotating speed acceleration and the first rotating speed acceleration is positive acceleration; S2, obtaining the highest rotating speed of the washing barrel within the 0-T detection time; S3,judging whether the highest rotating speed of the washing barrel within the time of 0-T is within the reference range of the preset highest rotating speed or not, wherein the preset highest rotating speed is the theoretical highest rotating speed after the motor accelerates for the time T at the first rotating speed acceleration; if not, executing the step S4; S4, sending a motor rotation stoppinginstruction to the motor to control the motor to stop rotating so that the washing barrel can stop rotating; if so, executing the step S5; and S5, the washing machine enters a normal working state. According to the motor control method and the washing machine, the defects in the prior art can be 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...
