Abstract

An appliance including a module-receiving cavity disposed in the appliance. Also included is a removable module disposed in the module-receiving cavity, and at least one ice modification member disposed inside the removable module. A motor is operably connected with the removable module and includes an output shaft that extends into the removable module. An impeller is connected with the output shaft proximate to the at least one ice modification member, the impeller being operable between a first ice manipulating condition defined by a first directional rotation of the impeller, and a second ice manipulating condition defined by a second directional rotation of the impeller. An ice chute is located proximate the ice modification member for dispensing ice.

4. The appliance of claim 1, wherein the single outwardly extending member of the impeller extends outwardly from the output shaft and includes an opposing double helix geometry.

5. The appliance of claim 1, wherein the at least one ice modification member includes a first blade and a second blade, wherein the first and second blades are stationary with respect to a base of the ice manipulation module.

6. The appliance of claim 5, wherein the first blade is an ice shaving blade and wherein the second blade is an ice crushing blade.

7. The appliance of claim 1, further comprising a reservoir mounted to the module-receiving cavity, wherein the ice manipulation module is disposed at least partially within the reservoir upon attachment to the appliance.

8. The appliance of claim 1, further comprising:

a plurality of ice manipulation modules configured to be received by the module-receiving cavity, wherein the module-receiving cavity is configured to receive any one of the plurality of ice manipulation modules, wherein each of the plurality of ice manipulation modules performs two ice manipulating functions selected from the group consisting of shaving and crushing, shaving and cubing, or crushing and cubing.

9. An ice manipulation module comprising:

a housing adapted for alternative connection with and removal from a module-receiving cavity;

a first ice modification member and a second ice modification member, wherein each of the first and second ice modification members are disposed inside and attached to a base of the housing, wherein each of the first and second ice modification members are in a fixed position with respect to the housing, and wherein the first ice modification member is an ice shaving blade and wherein the second ice manipulation member is an ice crushing blade;

a motor operably connected with the ice manipulation module and including an output shaft extending into the ice manipulation module; and

an impeller connected with the output shaft proximate to the ice modification member, the impeller being operable between a first ice manipulating condition defined by a first directional rotation of the impeller, and a second ice manipulating condition defined by a second directional rotation of the impeller, wherein the first ice manipulating condition includes at least one of dispensing, crushing and shaving, and wherein the second ice manipulating condition includes at least one other of dispensing, crushing and shaving, and wherein the impeller includes an outwardly extending curved portion that rotates to perform the first and second ice manipulating conditions, and wherein when the first and second ice manipulating conditions are crushing and shaving, the outwardly extending curved portion is further operable to at least partially perform a dispensing function.

10. The ice manipulation module of claim 9, wherein the impeller extends outwardly from the output shaft and the outwardly extending curved portion includes a rear end and a first side having a first angle and a second side having a second angle, wherein the first angle opposes the second angle, and wherein the first and second sides descend toward a central axis of the outwardly extending curved portion and intersect at a front location of the outwardly extending curved portion along the central axis, wherein the outwardly extending curved portion includes a blade curvature between the front location and the rear end defining a partially enclosed scoop, wherein the outwardly extending curved portion directs material downward in the first and second ice manipulating conditions, and wherein the impeller is free of additional outwardly extending portions.
