Abstract:
1. Ice flap device for a refrigerator, comprising a flap unit movable between an open position and a closed position, the flap unit releasing a dispenser aperture for dispensing ice in its open position and blocking the dispenser aperture against dispensing ice in its closed position; a motorized drive mechanism for driving the flap unit between the open and closed position thereof, the drive mechanism including an a.c. motor and a first electrical switch disposed in a supply circuit of the a.c. motor and switching depending on a user action, wherein the first electrical switch permits the a.c. motor to be turned on in response to the user action for a movement of the flap unit from the closed position in the direction of the open position; wherein at least one further electrical switch is disposed in the supply circuit of the a.c. motor; and wherein the a.c. motor is a polyphase motor operable in both directions of rotation, in which the relative phase position of at least two phase voltages is dependent on the switching state of at least one of the switches.
