Description
Technical field
The utility model is related to a kind of use in washing machine safety switch, more particularly to a kind of foldable use in washing machine safety open
Close.
Background technology
Therefore must be to this setting safeguard construction.Safety switch is typically provided with washing machine, the safety switch of washing machine will
There are two kinds of functions：Function 1, washing machine is stopped operating after uncapping by safety switch controlled motor, prevent from causing the person
Damage.Function 2, washing machine Wash tub using dehydrating function when, exception is easily caused due to force unbalance in Wash tub
Vibration.This abnormal vibrations are small, influence dehydrating effect, washing machine is then easily damaged greatly.If collided in dehydration or
Intense vibration is produced, safety switch control washing machine also stops operating and prevents from causing bigger vibration or loss.
A kind of safety open of prior art includes plastic box type pedestal, built-in switch spring setting up and down, located at pedestal bottom
The dehydration barrel at subordinate end rocks shutdown iron swing rod and swing rod back-moving spring, is arranged at the horizontal door closure open-close on-off triggering thick stick of pedestal
Herringbone sliding block of pull switch reed on-off etc. is constituted in bar, and pedestal.When door for washing machine closure, prize out
Close lever to move up according to branch spot wobble, promote sliding block to move up, the lower reed of jack-up switch turns on contact closure, laundry machine dehydration work
Make；Door for washing machine is opened, and switch lever, which resets, to be moved down, so that former closure switch reed disconnects, dehydration barrel stops operating.Just
When being dehydration, under clothing position skew serious conditions, bucket rotates at a high speed, will produce it is very big wave, that bucket is produced very
Big waving is rear, just dangerous, so the swing rod for the safety switch that bucket will be bumped against beside it, swing rod is promoted
Afterwards, the electrical contact inside safety switch can be disconnected, and laundry computer board is connected to after this cut-off signal, can run offset correction journey
Sequence, such as allow washing machine to intake again, and impeller rotates clothing etc., and safety switch is exactly that excessive so individual letter is waved to individual bucket
Number.
