摘要

A safety device for preventing opening of the door of a washing machine during operation thereof, comprises a spring-loaded sliding bolt member (12) which blocks movement of the handle (9) of the door (7) of the machine when moved in direction B by a solenoid (15). A further solenoid (21) holds the bolt member in its fastening position. Unlocking of the door (7) occurs only at the end of a cycle after a delay caused by a bimetal (not shown) to allow the drum to stop. An auxiliary capacitive circuit releases the fastening if the power fails.
