Method.
Background technology
Washing machine is switched to dehydration mode from the washing mode of rotating, is the control for sending driving tractor in a program
Signal, tractor traction clutch makes clutch ratchet depart from what ratchet was realized.Motor rotates at a high speed under dehydration mode, if leading
Lead device is damaged or mechanical transmission mechanism failure, clutch is drawn not successfully, it will cause motor rotation blockage, although motor typically has
Overtemperature protection, but after know aftersensation, the performance of motor and life-span still can be affected.
The content of the invention
In order to solve problem of the prior art, the present invention provides a kind of detection method of motor for washer clutch operating,
Including motor, ratchet, ratchet, drainpipe, traction middle device, draw bar, tractor and proximity switch, the level of proximity switch
Signal sends into the I/O mouths of single-chip microcomputer；Prestored in single-chip microcomputer with clutch in the varying level signal corresponding to diverse location；From
Clutch is drawn by tractor by draw bar, and proximity switch successfully draws the position residing for clutch rear haulage bar located at tractor
Put；Traction middle device one end is connected with draw bar, and the other end is connected with the valve on drainpipe.
When washing machine selects low speed washing mode, the level signal of proximity switch is first judged, if what level signal was represented
Clutch position is the position of washing mode, then is run by normal flow motor.
When washing machine selects high speed dewatering pattern, the level signal of proximity switch is first judged, if what level signal was represented
Clutch position is the position of dehydration mode, then is run by normal flow motor；Conversely, then not motor, to protect
Motor.
Further, during washing machine low speed washing mode, tractor does not work, and tractor does not drive draw bar, clutch
In non-traction state, the ratchet of clutch is without departing from ratchet, and traction middle device is not driven at the valve on drainpipe, valve
In closed mode；During washing machine high speed dewatering pattern, tractor work, tractor drives draw bar, and clutch is in traction shape
State, the ratchet of clutch departs from ratchet, and traction middle device drives the valve on drainpipe, and valve is in opening, realizes
Drain function.
Single-chip microcomputer monitors the level signal of proximity switch in real time by the way of timer interruption, to prevent under anti-avulsion aqueous mode
Motor unexpected stall during running at high speed.
Compared with prior art, the present invention is set by successfully drawing the location of clutch rear haulage bar in tractor
Proximity switch, the action of clutch is judged according to the level signal of proximity switch, can be prevented effectively from tractor and be damaged or machinery
The problem of transmission mechanism causes motor rotation blockage when failing, improves safety in utilization, and effectively extends the use longevity of washing machine
Life.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will make needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing.
Fig. 1 is the structural representation of the present invention, wherein：
1 is motor, and 2 be ratchet, and 3 be ratchet, and 4 be drainpipe, and 5 be traction middle device, and 6 be draw bar, and 7 be traction
Device, 8 be proximity switch, and 9 successfully draw the location of clutch rear haulage bar for tractor.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1, the present embodiment provides the detection method of the clutch operating of motor for washer 1, including motor 1, ratchet 2,
Ratchet 3, drainpipe 4, traction middle device 5, draw bar 6, tractor 7 and proximity switch 8, the level signal of proximity switch 8 are sent
Enter the I/O mouths of single-chip microcomputer；Prestored in single-chip microcomputer with clutch in the varying level signal corresponding to diverse location；Clutch by
Tractor 7 is drawn by draw bar 6, and proximity switch 8 successfully draws the location of clutch rear haulage bar 6 located at tractor 7；
Traction one end of middle device 5 is connected with draw bar 6, and the other end is connected with the valve on drainpipe 4.
When washing machine selects low speed washing mode, the level signal of proximity switch 8 is first judged, if what level signal was represented
Clutch position is the position of washing mode, then is run by normal flow motor 1.
When washing machine selects high speed dewatering pattern, the level signal of proximity switch 8 is first judged, if what level signal was represented
Clutch position is the position of dehydration mode, then is run by normal flow motor 1；Conversely, then not motor 1, to protect
Protect motor 1.
During washing machine low speed washing mode, tractor 7 is not worked, and tractor 7 does not drive draw bar 6, and clutch is in not
Traction state, the ratchet 3 of clutch is without departing from ratchet 2, and traction middle device 5 does not drive the valve on drainpipe 4, and valve is in
Closed mode；During washing machine high speed dewatering pattern, tractor 7 works, and tractor 7 drives draw bar 6, and clutch is in traction shape
State, the ratchet 3 of clutch departs from ratchet 2, and traction middle device 5 drives the valve on drainpipe 4, and valve is in opening,
Realize drain function.
9 show tractor 7 and successfully draw the location of clutch rear haulage bar 6 in figure.
Single-chip microcomputer monitors the level signal of proximity switch 8 in real time by the way of timer interruption, to prevent anti-avulsion aqueous mode
Lower motor 1 unexpected stall during running at high speed.
Compared with prior art, the present invention is set by successfully drawing the location of clutch rear haulage bar 6 in tractor 7
Put proximity switch 8, the action of clutch judged according to the level signal of proximity switch 8, can be prevented effectively from tractor 7 damage or
