Abstract

A dispensing unit is operatively associated with a refrigeration appliance for selectively dispensing water and ice at a dispensing station. The dispensing unit includes an actuator that is movable to selected positions in order to support the dispensing of the water and ice. The dispensing unit can include a passageway through which ice is dispensed, and an ice door can be provided for selectively opening and closing the passageway to the dispensing of ice. In one aspect, the ice door can be opened and closed mechanically and in another aspect, the ice door can be opened and closed electromechanically. The dispensing unit also can provide for the position of a water-dispensing nozzle to be adjusted for the purpose of dispensing water to receptacles outside a recessed area at which the nozzle is located and to provide for the activation of illuminating devices to indicate operating conditions at the refrigeration appliance.

First claim

What is claimed is:

1. A dispensing unit operatively associated with a refrigeration appliance for selectively dispensing water and ice at a dispensing station at the refrigeration appliance, the dispensing unit including:
an actuator movable from a first position, at which first position the actuator supports neither the dispensing of water nor the dispensing of ice at the dispensing station, to a second position, at which second position the actuator supports the dispensing selectively of water and ice at the dispensing station, the actuator including a passageway through which ice can be selectively dispensed at the dispensing station when the actuator is in the second position and ice has been selected to be dispensed;
an ice door closing off the passageway to the dispensing of ice when the actuator is in the first position and opening the passageway to the dispensing of ice when the actuator is in the second position and ice has been selected to be dispensed;
a flapper coupled to the ice door and having a seating surface configured to seat against the bottom of a chute through which ice is delivered to the passageway; and
a flapper supporting member coupled to the ice door and supporting the flapper, the flapper supporting member being joined to the flapper by a universal adjusting member, the universal adjusting member comprising a ball and socket joint whereby the attitude of the flapper can be adjusted as the ice door engages the bottom of the chute so that the seating surface of the flapper seats against the bottom of the chute in a manner essentially entirely closing off the opening at the bottom of the chute to the passage of ice to the passageway.

2. The dispensing unit of claim 1 , wherein the flapper supporting member includes two interior legs, each of which includes an extremity that extends down over a collar of the flapper.

3. The dispensing unit of claim 2 , wherein the flapper supporting member further includes two exterior legs that each include an exterior leg intermediate section that extends down over the collar of the flapper.

4. The dispensing unit of claim 3 , wherein the two interior legs and the two exterior legs are attached to an annulus that comprises the socket of the ball and socket joint, and a ball attached to the flapper is retained within the annulus.

5. The dispensing unit of claim 3 , wherein each of the exterior leg intermediate sections are joined to a slotting bracket that defines a pair of slots that each receive a respective actuating member of the actuator.

6. The dispensing unit of claim 5 , further comprising a gear rod with a first toothed wheel and the second toothed wheel, and a friction damper operatively connected to the gear rod.

7. The dispensing unit of claim 6 , further comprising an arcuate toothed wheel located at the top of each slotting bracket that engages and drives a respective one of the first toothed wheel and the second toothed wheel of the gear rod, whereby rotation of the ice door thereby drives rotation of the gear rod, which rotation is damped by the friction damper.

8. The dispensing unit of claim 6 , further comprising a mounting rod to which is mounted the ice door, and each end of the mounting rod is fixed to a respective one of the arcuate toothed wheels.

9. The dispensing unit of claim 1 , further comprising an electric motor operatively associated with the ice door and configured to cause the ice door to open the passageway to the dispensing of ice whenever the actuator is in the second position and ice has been selected to be dispensed at the dispensing station.
