ABSTRACT:
A "no-heat" clothes dryer is provided herein. It includes a drying chamber having an access opening. An access door is hinged to the access opening, the door being adapted to close the access opening in an hermetically sealed manner. Means, which are conventional but which are adapted to be actuated only when the door is closed, are provided to subject the interior of the drying chamber to a vacuum. Means are provided which positively interrelate the breaking of the vacuum with the opening of the access door. Such means include a door handle having a lever which is pivotally mounted to move between a closed position, where it locks the door in a closed position, and an open position, where it simultaneously opens vents to the interior of the drying chamber and unlocks the door to enable opening thereof. The particular structure of the door handle is as follows: (i) a main framework; (ii) an anchor plate at one corner thereof; (iii) a release lever pivotally secured to the anchor plate; (iv) a plunger extending through the door, and connected to the free end of the release lever normally resiliently urged to come into locking engagement with a lock on the door frame; and (v) means associated with the movement of the plunger out of locking engagement with the lock to open vent means in the door. In this way, clothes are dried without the expenditure of wasteful heat energy in a home dryer which includes a fail-safe safety feature for the door opening.
