Description

A kind of washing machine of use single-phase pole-changing double-speed motor

Technical field

The present invention relates to a kind of washing machine, more particularly to a kind of washing machine of use single-phase pole-changing double-speed motor.

Background technology

Existing automatic washing machine, its washing and dehydration are all to provide power by same motor.Due to washing Rotating speed during with dehydration is mutually far short of what is expected, laundry function is smoothly worked, otherwise exactly slow down and combine by belt pulley and subtract Speed clutch is realized；It is exactly that the motor has the double speed function of matching with washing machine；During due to laundry washer and Rotating speed difference all too great disparity during dehydration, only using frequency converter and the matching used mode of variable-frequency motor, this double speed side Formula could be realized.

Existing automatic washing machine, motor must be ceaselessly during in order to reduce the tangled up and knotted of clothing, washing and rinsing Forward and backward.During due to washing and rinsing, dehydrating shaft must separate and be braked with washing shaft, it is impossible to rotate；And when dehydration, Dehydrating shaft must be again be released and linked together with washing shaft, synchronous axial system.Accomplish this point, it is necessary to nothing can be accomplished Rotated forward by motor or inverted, can reliably drive washing shaft to rotate, again while can be closed with dehydrating shaft or be energy Separate while can be locked.

In the case where common monophase machine is used in order to be able to reach this purpose, existing rotary drum washing machine is to pass through The helical spring that is coiled into same side's bar spring steel wire, the difference of the hollow shaft enclasping force disconnected from each other to two are realized 's.One of hollow shaft is connected with belt pulley, synchronous rotary；Another hollow shaft is connected with brake disc, synchronous axial system.

Because scribbling lubricating grease between spring and hollow shaft, when washing and rinsing, because one end of spring is by ratchet Limitation, with motor steering change, spring always have to two enclasping forces of hollow shaft a pine some, one tightly, One end of pine produces skidding, and the rotating torque of transmission is small, while brake disc is braked, small torque cannot drive dehydrating shaft to rotate. When to the water smoking, brake disc and ratchet are all discharged simultaneously, and two hollow shafts are all held tightly by spring simultaneously, non-slip, company Integrally, due to there is a hollow shaft to be linked together with belt pulley, thus dehydrating shaft just with belt pulley synchronous rotary, enter Row is dehydrated.

This there is very big uncertainty：The torque that may be transmitted when lubricating grease is excessive not enough, still can skid, and turn Speed can lower；The phenomenon interfered with brake can be caused when lubricating grease is very few because mill is examined heating and held tightly again.

This clutch mode, the waste for both having caused energy, there is also and can be moved when should not moving sometimes；Should not the stopping time Situation about stop.
