Problems solved by technology
In the dehydration mode, the motor rotates at high speed. If the tractor is damaged or the mechanical transmission mechanism fails, the clutch will not be pulled successfully, which will cause the motor to stall. Although the motor generally has overheat protection, the performance and life of the motor will still be affected by hindsight. influences

Embodiment Construction
[0012] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0013] see figure 1 , this embodiment provides a method for detecting the clutch action of the washing machine motor 1, including the motor 1, the ratchet 2, the pawl 3, the drain pipe 4, the traction intermediate device 5, the traction rod 6, the tractor 7 and the proximity switch 8. The proximity switch 8 The level signal is sent to the I / O port of the single-chip microcomputer; the different level signals corresponding to the different positions of the clutch are pre-stored in the single-chip microcomputer; the clutch is pulled by the tractor 7 through the traction rod 6, and the proximity switch 8 is set in the tractor 7 to successfully pull the clutch The position of the rear drawbar 6; one end of the drawing intermediate device 5 is con...

The invention discloses a detection method for action of a motor clutch of a washing machine. The detection method comprises the steps of judging a level signal of a proximity switch when the washing machine selects a low-speed washing mode, driving a motor to operate according to a normal procedure if a clutch position expressed by the level signal is in a washing mode position, judging the level signal of the proximity switch when the washing machine selects a high-speed dehydration mode, driving the motor to operate according to the normal procedure if the clutch position expressed by the level signal is a dehydration mode position, and not driving the motor on the contrary to protect the motor, wherein the proximity switch is arranged in a position of a pull rod after a puller successfully pulls the clutch. The detection method judges the action of the clutch according to the level signal of the proximity switch, so that the stalling of the motor caused by damage of the puller or failure of a mechanical transmission mechanism can be effectively avoided; the use safety is improved; the service life of the washing machine is effectively prolonged.
Description
technical field [0001] The invention relates to the field of household appliance control, in particular to a method for detecting the action of a washing machine motor clutch. Background technique [0002] Switching the washing machine from the forward and reverse washing mode to the dehydration mode is realized by sending out a control signal to drive the tractor in the program, and the tractor pulls the clutch to make the clutch pawl disengage from the ratchet. In the dehydration mode, the motor rotates at high speed. If the tractor is damaged or the mechanical transmission mechanism fails, and the clutch is not successfully pulled, the motor will be blocked. Although the motor generally has overheat protection, the performance and life of the motor will still be affected. influences. SUMMARY OF THE INVENTION [0003] In order to solve the problems of the prior art, the present invention provides a method for detecting the action of a washing machine motor clutch, inclu...
