A method of heating a dispenser door by applying direct heat to only a peripheral region of a front layer of the door at a rate sufficient to heat an edge surface of the door to a point above zero degrees Centigrade. In one embodiment this is done by placing a perimeter heater in a flange attached to the rear end of a tubular wall extending from the periphery of a central region of the front layer of the door.

Heated dispenser door and method

A method of controlling a dispenser duct door, including positioning an upper side of the door, in a closed position, in a door-opening direction, and rotating a bottom end of the door to a partially open position vertically under the upper side of the door in response to an opening signal. The bottom end of the door is rotated further in the door-opening direction in response to ice hitting a rear of the door and is returned to the partially open position. After a predetermined delay, the bottom end of the door is returned to the closed position.

Ice dispenser duct door mechanism

The present invention relates to a heat pump that utilizes unidirection refrigerant wherein air directed across the condenser and evaporator is redirected for different operations. While the heat pump is operating in the cooling mode, manually operable dampers are positioned so that outdoor air is circulated through the condenser and indoor air is circulated through the evaporator. Conversely, in the heating mode, the dampers are manually positioned so that outdoor air is circulated through the evaporator; and indoor air is circulated through the condenser for heating the air.
