Abstract:
A locking latch for an appliance provides an improved three-wire interface that reduces the chance of malfunction if the door is forcibly opened when it is in the lock state and a bi-stabile actuator is used. In one embodiment, the door switch is positioned to disengage the major load of the washing machine when the doors open, regardless of the lock or unlock state.
Abstract:
A motorized lock for a vending machine [10] provides a simple lever mechanism that provides two separate points of engagement between the door [14] and the machine to resist tampering and provide for more even pull in of a gasketed door.
Abstract:
A vent fan (38) for use with the dishwasher (10) and providing a vent door covering (49,90) the opening associated with a motorized fan (38) employs a mechanical coupling between the fan motor (34) and vent door to eliminate the need for a separate vent door actuator by using energy of the fan motor (34) to accomplish the actuation.
Abstract:
A vent system (24) for a dishwasher provides a mixing chamber (30) receiving high humidity air from a downdraft dishwasher vent system or the like and mixes this air with dry air before discharging it from the dishwasher to reduce the humidity of the discharged air moderating condensation problems.
Abstract:
An electrical linear actuator (44) employs a reversible motor (46) driving a helical wire spring (52). The coils of the spring engage a follower (44, 46) that moves along the axis (42) of the spring with rotation of the motor (46) to provide linear motion. This actuator (44) may be used as a linear drive in an appliance lock.
