Abstract

A door locking device for locking the door of a washing machine for the duration of its operating cycle comprises a heating plate (15) having a positive temperature coefficient, first and second bimetal members (17, 25) arranged to be heated and thus deformed by the plate and a pivotally mounted contact arm (18) having both an electrical contact (19) and a latch pin (21) at its free end and being elastically connected to the first bimetal member 17 in such a way as to be actuated in one direction when said first bimetal member 17 reaches a preset heating temperature and in the other direction on cooling and said second bimetal member 25 being deformed when a given ambient temperature is exceeded and acting against said contact arm 18 to actuate said contact arm when said first bimetal member 17 is no longer heated. <IMAGE>
