ABSTRACT:
A ice maker employing a relatively thin ice tray with sealed ice cube receptacles and having a freezing chamber of relatively small volume cooled by a high capacity cooling plate. The ice cube receptacles are sealed by a frangible cover to keep liquid water therein and to maintain frozen water in a sanitary state until the frangible cover is ruptured for the ice cubes to be used. The ice make housing also may include other chambers for holding containers of food and drink. The cooling surface of the freezing chamber may be sloped for drainage and the ice maker provided with a spring loaded device for ejecting the ice tray when a housing door is opened. Detection switches and indicator lights may be actuated by insertion and removal of the tray. Multiple freezing chambers may be jointly cooled by a single cooling plate.
