Abstract
Abstract A drinking-glass or dish washer with a top hood whose upper surface lies flush with the upper surface of a work counter, the device having a glass- or dish-receiving compartment positioned below the hood and normally closed by a three-sided door. The door can be moved down into the wash water tank to gain access to the drinking glass or dish washing and rinsing compartment rather than raise the door above the hood. In one form of our device the door is counterbalanced and will remain in closed or opened position into which it has been manually moved. In a modified form of the device, an automatic door lock will hold the manually closed door in locked position until the completion of the wash and rinse cycles whereupon the lock will free the door and it will move downwardly into open position automatically.
