Abstract

An ice maker for producing and storing ice pieces. The ice maker is mountable to a liner of a fresh food compartment at an intersection of a top wall and a lateral side wall of the liner. The ice maker includes an ice tray for forming ice pieces. An ice bin receives and stores ice pieces produced by the ice tray. A housing contains the ice tray and ice bin. The housing has a first side, a second side, a bottom and a top. A first cavity is formed in the first side and a second cavity is formed in the bottom. A thermal insulation is disposed in the first cavity and the second cavity. The second side of the ice maker housing does not include thermal insulation.

First claim

What is claimed is:

1. A refrigeration appliance comprising:
a fresh food compartment for storing food items in a refrigerated environment having a target temperature above zero degrees Centigrade;
a liner defining said fresh food compartment and comprising a top wall, a bottom wall, and a pair of opposing lateral side walls; and
an ice maker disposed within the fresh food compartment for producing and storing ice pieces and mounted to the liner at an intersection of the top wall and one of the pair of opposing lateral side walls of the liner, the ice maker comprising:
an ice tray for forming ice pieces,
an ice bin for receiving and storing ice pieces produced by the ice tray, and
a housing containing the ice tray and ice bin, the housing having a first side, a second side, a bottom and a top and comprising:
a first housing portion defining at least one of the bottom and the first side of the housing;
a second housing portion defining at least one of the top and the second side of the housing; and
thermal insulation disposed on the bottom, the first side and the top of the housing,

wherein the second side of the ice maker housing is free of thermal insulation and abuts said one of the pair of opposing lateral side walls, and
wherein said thermal insulation comprises:
a first insulation member interposed between an exterior surface of the first side and an interior surface of the first side;
a second insulation member interposed between an exterior surface of the bottom and an interior surface of the bottom; and
a third insulation member interposed between an exterior surface of the top and the top wall of the liner,
wherein the first insulation member, the second insulation member, and the third insulation member are separate from one another.

2. The refrigeration appliance of claim 1 , wherein at least one of the first housing portion and the second housing portion is L-shaped or U-shaped.

3. The refrigeration appliance of claim 1 , wherein the top wall of the liner comprises a recess, and a tab extends upwards beyond the top of the housing and is received within the recess of the liner.

4. The refrigeration appliance of claim 1 , wherein each of the first, second, and third insulation members comprises a rigid pre-formed EPS panel.

5. The refrigeration appliance of claim 1 , further comprising:
an anchor disposed in the top wall of the liner, an end of the anchor extending through the top wall of the liner and having a flange for engaging a receiving opening formed in the top of the housing.

6. The refrigeration appliance of claim 1 , further comprising:
an anchor disposed in said one of the pair of opposing lateral side walls; and
a fastener extending through the second side of the housing into the anchor for securing the housing to the liner.

7. The refrigeration appliance of claim 1 , further comprising:
an opening in a back wall of the liner positioned proximate the ice maker; and
a backplate for receiving an evaporator of the ice maker, the backplate attachable to the back wall of the liner to enclose the opening in the back wall.

8. A refrigeration appliance comprising:
a fresh food compartment for storing food items in a refrigerated environment having a target temperature above zero degrees Centigrade;
a liner defining said fresh food compartment and comprising a top wall, a bottom wall, and a pair of opposing lateral side walls; and
an ice maker disposed within the fresh food compartment for producing and storing ice pieces and mounted to the liner at an intersection of the top wall and one of the pair of opposing lateral side walls, the ice maker comprising:
an ice tray for forming ice pieces,
an ice bin for receiving and storing ice pieces produced by the ice tray,
a housing containing the ice tray and ice bin, the housing having a first side, a second side, a bottom and a top, a first cavity formed in the first side and a second cavity formed in the bottom, and
a thermal insulation disposed in the first cavity and the second cavity,
wherein the second side of the ice maker housing does not include thermal insulation and abuts said one of the pair of opposing lateral side walls, and
wherein the housing comprises:
a first housing portion defining an exterior surface of the bottom and an exterior surface of the first side; and
a second housing portion defining the second side and an interior surface of the bottom,

wherein the first housing portion and the second housing portion define the second cavity in the bottom.

9. The refrigeration appliance of claim 8 , wherein the housing further comprises:
a third housing portion defining an exterior surface of the top and an interior surface of the first side,
wherein the first housing portion and the third housing portion define the first cavity in the first side.

10. The refrigeration appliance of claim 9 , wherein said thermal insulation comprises:
a first insulation member interposed between the exterior surface of the first side and the interior surface of the first side;
a second insulation member interposed between the exterior surface of the bottom and the interior surface of the bottom; and
a third insulation member interposed between the exterior surface of the top and the top wall of the liner,
wherein the first insulation member, the second insulation member, and the third insulation member are separate from one another.

11. The refrigeration appliance of claim 10 , wherein each of the first, second, and third insulation members comprises a rigid pre-formed EPS panel.

12. The refrigeration appliance of claim 8 , wherein the top wall of the liner comprises a recess, and a tab extends upwards beyond the top of the housing and is received within the recess of the liner.

13. The refrigeration appliance of claim 12 , wherein the tab extends along an edge between the first side and the top of the housing.

14. The refrigeration appliance of claim 8 , further comprising:
an anchor disposed in the top wall of the liner, an end of the anchor extending through the top wall of the liner and having a flange for engaging a receiving opening formed in the top of the housing.

15. The refrigeration appliance of claim 8 , further comprising:
an anchor disposed in said one of the pair of opposing lateral side walls; and
a fastener extending through the second side of the housing into the anchor for securing the housing to the liner.

16. The refrigeration appliance of claim 8 , further comprising:
an opening in a back wall of the liner positioned proximate the ice maker; and
a backplate for receiving an evaporator of the ice maker, the backplate attachable to the back wall of the liner to enclose the opening in the back wall.

17. An ice maker for producing and storing ice pieces, the ice maker mountable to a liner of a fresh food compartment at an intersection of a top wall and a lateral side wall of the liner, the ice maker comprising:
an ice tray for forming ice pieces,
an ice bin for receiving and storing ice pieces produced by the ice tray,
a housing containing the ice tray and ice bin, the housing having a first side, a second side, a bottom and a top, a first cavity formed in the first side and a second cavity formed in the bottom, and
a thermal insulation disposed in the first cavity and the second cavity,
wherein the second side of the ice maker housing does not include thermal insulation, and
wherein the housing comprises:
a first housing portion defining an exterior surface of the bottom and an exterior surface of the first side; and
a se
