Abstract

An ice making assembly includes an ice bucket with an agitator rotatably mounted within the ice bucket. The agitator may be rotated by a dispenser motor. The agitator may be coupled to the dispenser motor via a fork connected to the motor and a socket connected to the agitator. The fork is selectively engagable with the socket, and the fork transfers torque from the dispenser motor to the agitator via the socket when the fork engages the socket. The ice making assembly may be provided in a refrigerator appliance.

First claim

What is claimed is:

1 . An ice making assembly, comprising:
an ice maker configured to form ice pieces within the ice maker, the ice maker including an ice chute to direct the ice pieces from the ice maker; an ice bucket defining a storage volume, the ice bucket including an opening in communication with the ice chute to receive the ice pieces into the storage volume; an agitator rotatably mounted within the storage volume of the ice bucket; a dispenser motor operatively coupled to a drive shaft; a socket connected to a first end of the agitator; a fork positioned on the drive shaft, the fork selectively engagable with the socket, whereby the fork transfers torque from the drive shaft to the agitator via the socket when the fork engages the socket; and a lever configured to move the fork relative to the drive shaft from an engaged position to a disengaged position, wherein the fork clears the socket in the disengaged position such that the ice bucket may be removed from the ice making assembly when the fork is in the disengaged position.

2 . The ice making assembly of claim 1 , wherein the fork comprises a plurality of tines and one or more slots defined between adjacent tines of the plurality of tines, wherein the socket comprises one or more ribs corresponding to the slots of the fork, and the ribs of the socket are received within the slots of the fork when the fork engages the socket.

3 . The ice making assembly of claim 1 , wherein the drive shaft comprises a longitudinal axis, the longitudinal axis of the drive shaft defines an axial direction, and wherein the fork is movable relative to the drive shaft along the axial direction.

4 . The ice making assembly of claim 3 , wherein the lever is configured to move the fork relative to the drive shaft along the axial direction between the engaged position and the disengaged position.

5 . The ice making assembly of claim 1 , further comprising a spring, the spring biasing the fork towards the engaged position.

6 . The ice making assembly of claim 1 , wherein the fork comprises a neck and a flange, the neck comprising a first outer diameter and the flange comprising a second outer diameter greater than the first outer diameter of the neck, further comprising a yoke partially encircling the neck of the fork, the yoke comprising an inner diameter, the inner diameter of the yoke greater than the first outer diameter of the neck of the fork and less than the second outer diameter of the flange of the fork.

7 . The ice making assembly of claim 6 , wherein the lever is rotatably connected to the yoke, the lever rotatable between a first position and a second position wherein the yoke engages the flange of the fork to move the fork relative to the drive shaft from the engaged position to the disengaged position when the lever rotates from the first position to the second position.

8 . The ice making assembly of claim 1 , wherein the fork comprises a chamfered portion and the socket comprises a chamfered portion.

9 . The ice making assembly of claim 1 , wherein the ice bucket comprises a recessed handle.

10 . The ice making assembly of claim 1 , wherein the dispenser motor is operatively coupled to the drive shaft via a gearbox.

11 . A refrigerator appliance comprising:
a housing defining a chilled chamber; an ice making assembly disposed within the housing, the ice making assembly comprising:
an ice maker configured to form ice pieces within the ice maker, the ice maker including an ice chute to direct the ice pieces from the ice maker;
an ice bucket defining a storage volume, the ice bucket including an opening in communication with the ice chute to receive the ice pieces into the storage volume;
an agitator rotatably mounted within the storage volume of the ice bucket;
a dispenser motor operatively coupled to a drive shaft;
a socket connected to a first end of the agitator;
a fork positioned on the drive shaft, the fork selectively engagable with the socket, whereby the fork transfers torque from the drive shaft to the agitator via the socket when the fork engages the socket; and
a lever configured to move the fork relative to the drive shaft from an engaged position to a disengaged position, wherein fork clears the socket in the disengaged position such that the ice bucket may be removed from the ice making assembly when the fork is in the disengaged position.

12 . The refrigerator appliance of claim 11 , wherein the fork comprises a plurality of tines and one or more slots defined between adjacent tines of the plurality of tines, wherein the socket comprises one or more ribs corresponding to the slots of the fork, and the ribs of the socket are received within the slots of the fork when the fork engages the socket.

13 . The refrigerator appliance of claim 11 , wherein the drive shaft comprises a longitudinal axis, the longitudinal axis of the drive shaft defines an axial direction, and wherein the fork is movable relative to the drive shaft along the axial direction.

14 . The refrigerator appliance of claim 13 , wherein the lever is configured to move the fork relative to the drive shaft along the axial direction between the engaged position and the disengaged position.

15 . The refrigerator appliance of claim 11 , further comprising a spring, the spring biasing the fork towards the engaged position.

16 . The refrigerator appliance of claim 11 , wherein the fork comprises a neck and a flange, the neck comprising a first outer diameter and the flange comprising a second outer diameter greater than the first outer diameter of the neck, further comprising a yoke partially encircling the neck of the fork, the yoke comprising an inner diameter, the inner diameter of the yoke greater than the first outer diameter of the neck of the fork and less than the second outer diameter of the flange of the fork.

17 . The refrigerator appliance of claim 16 , wherein the lever is rotatably connected to the yoke, the lever rotatable between a first position and a second position wherein the yoke engages the flange of the fork to move the fork relative to the drive shaft from the engaged position to the disengaged position when the lever rotates from the first position to the second position.

18 . The refrigerator appliance of claim 11 , wherein the fork comprises a chamfered portion and the socket comprises a chamfered portion.

19 . The refrigerator appliance of claim 11 , wherein the ice bucket comprises a recessed handle.

20 . The refrigerator appliance of claim 11 , wherein the dispenser motor is operatively coupled to the drive shaft via a gearbox.
