Abstract
In a refrigerator of the domestic type where the tray of an ice making apparatus is turned down to permit ice pieces to be discharged therefrom, the present apparatus takes advantage of the characteristic of a synchronous motor incorporated therein. Namely, the direction of rotation of the synchronous motor is adapted to be periodically changed and no electrical change-over switching means is included in the apparatus. In accordance with the periodic conversion of the direction of rotation of the motor, the tray is adapted to be turned down and up, alternately. Furthermore, according to the present invention, whenever the ice making tray has been turned down or up, a twisting actuation is applied to the tray, thereby to make the ice pieces separate from the wall of the tray.
