Abstract: A mechanical coupling mechanism links an access door, a push-to-start button, and a switch controlling power to machinery behind the access door. The coupling mechanism permits the door to be open and the switch to be open, the door to be closed and the switch to be open, and the door to be closed and the switch to be closed, while forbidding the door to be open and the switch to be closed. The coupling precludes an operator shifting from a condition with the door open and the switch open to that in which the door is closed and the switch is closed with a single action.

Abstract: The invention relates to a method and to a device for carrying out the method for drying crockery in a dishwasher with a rinse container closeable by means of a door. By means of two or three successive different method steps, the drying is improved. The method steps include a drainage phase, a drying phase with blower or condenser and an automatic, partial opening of the door.

Abstract: An apparatus for cleaning paint guns and related accessories includes a housing defining a washing chamber, a fluid manifold located within the washing chamber having fluid jets attached thereto, a solvent storage tank, an air-flow system and a fluid distribution system for driving the solvent from the storage tank to the manifold for washing the parts mounted on the fluid jets. A timer is provided for control of the washing cycle time and a preset time may be used which is greater than the time required to empty the storage tank thereby providing a drying cycle. In one aspect, the solvent storage tank is provided with a movable barrier dividing the tank into an air chamber and a solvent chamber with the air-flow system coupled to the air chamber so that when pressurized the movable barrier drives the solvent through the fluid distribution system to the manifold. A removable solvent tank is included which is coupled to the solvent chamber by the fluid distribution system.

Abstract: An appliance control circuit used in a dishwasher which includes only a single door switch which is used both for disabling/enabling the AC voltage components of the dishwasher and which also provides an input to the microprocessor of the control circuit. A zero crossing conditioning circuit is also included to condition the door switch signal and to provide it to the microprocessor. The microprocessor control is electrically isolated from the grounded side of the line voltage.

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.

Abstract: A dishwasher having a tank containing wash water disposed below a dishwashing compartment and means for removing water from the tank and forcing it through upper and lower revolving spray arms for washing the dishes, the wash water being returned to the tank by gravity. A hood overlies the top of the wash and rinse compartment and a door for closing the compartment is movable downwardly into the tank for opening the compartment, the weight of the door being yieldingly held in closed or open position by spring biased toggle joints that are positioned in the tank. A U-shaped member is removably secured to the hood that overlies the dishwashing compartment and this member acts as a door stop when the door is in its raised and closed position. A removal of the member from the hood permits the door to be removed from the dishwasher.

Abstract: The environment of the invention comprises work degreasing apparatus wherein a tank contains liquid solvent to be vaporized by a heater for degreasing contact with work introduced into the tank, the vapor being subject to condensation, there also being a tank cover having open and closed positions. The inventive improvement comprises means responsive to closing of the cover to control the heater to reduce heat transfer to the liquid solvent, and also responsive to opening of the cover to control the heater to increase heat transfer to the liquid solvent.

Abstract: Safety device for a dishwashing machine comprising a locking means allowing limited angular movement of the machine closure in case of vapor pressure build-up and a microswitch interrupting the pump circuit upon such angular movement or inadvertent opening of the closure.
