ABSTRACT:
In a conventional dishwashing machine having a front door biased to closed position by a pair of tension springs connected to rearwardly-extending arms of the door hinges, the addition of a pair of spring-loaded pushers acting on said arms through a restricted stroke and with a door-opening force overcoming the door-closing force of said tension springs. A solenoid-operated latch releasably locks the door in closed position. Said latch is operated by the timer controlled switching assembly of the machine, so as to release the door at the end of the rinsing cycle. Thus, the drying cycle is effected solely through free circulation of ambient air within the washing compartment through the partially-open door opening.
