Recoverable domestic ice maker

摘要

An ice making apparatus includes a mold in which water is frozen to form an ice body. Also included are an electric motor and an ejector blade for ejecting the ice body from the mold. An electric heater in heat transfer association with the mold is operable to free the ice bodies from the mold prior to the ejector blade ejecting the ice bodies. A control circuit includes a thermostat responsive to temperature of water in the mold. A thermostat switch is controlled by the thermostat to initiate operation of the motor for ejecting the ice body upon complete freezing thereof and concurrently energizing the heater. An electric circuit includes the thermostat switch, the motor and a second switch controlled by the operation of the motor for maintaining energization of the motor independently of the first switch and causing the thermostat switch to control further energization of the heater whereby the thermostat switch de-energizes the heater within a single revolution of the ejector blade. The motor also drives a cam and cam follower for controlling a sensing arm for sensing a full ice condition. The ice maker includes structure for suspending operation of the ice maker in the event that the sensing arm is obstructed.
