摘要： An automatic ice maker adapted for use in a refrigerator includes an ice-making tray rotatable between an upright ice-making position and an inverted ice-discharging position by a motor. A container is disposed beneath the tray for receiving ice when the tray is in the inverted position. First and second switches are each moved between first and second states in response to rotation of the tray. The second switch can be moved to its second state in response to the container being full of ice. Whenever the refrigerator is started-up, e.g., after a power outage, a controller determines whether both of the switches are in their first states. If so, an ice making operation is performed. If not, the motor is actuated in a manner tending to rotate the tray to its upright position. When the tray reaches its upright position, a stop is contacted, whereupon a load is generated at the motor, causing the controller to stop the motor.

摘要： An automatic ice maker includes an ice-making tray rotatable between an upright ice-making position, and an inverted ice-discharging position. A container disposed beneath the tray receives the discharged ice. A cam wheel rotates with the tray and includes first and second cams that actuate first and second switches, respectively. A controller connected to the switches determines the position of the tray on the basis of the states of the switches. A lever detects whether the container is full of ice. When the container is full, the lever actuates the second switch in order to prevent further ice-making operations, regardless of the orientation of the first and second cams.
