Abstract

The invention discloses a gate lock switch and controlling means of washer. The gate lock switch comprising: switch casing; slide block which used to lock the pothook of gate in switch casing or separated from switch casing and that set on switch casing by mobile manner; lockpin which can hitch/loosen slide block; bimetallic strip which can move between the position of lockpin hitching slide block and loosening slide block; switch which can contact with contact point when the lockpin moving to the place of hitching slide block; safety pole which can cutting switch contact point by the manner of moving lockpin when the door is opened by force. The provided gate lock switch and controlling means of washer by this invention can rapidly cut the power of washer electric driving device when the washer door be opened by force, thus there is no need to install gate switch, so that this can make the structure and control of washer more simple. In addition, the set magnet coil in washer can expedite the rupturing operation of electric driving device powder.
