Abstract

A refrigerator or ice making assembly may include a housing and a mold assembly. The housing may define a receiving chamber in fluid communication with an air duct. The housing may extend transversely from a first housing end and a second housing end. The housing may define a first mounting slot at the first housing end and a second mounting slot at the second housing end. The mold assembly may include a frame, a heat exchanger mounted to the frame, an ice mold, and a latch bar. The ice mold may be supported on the heat exchanger and define a mold cavity for receiving water. The latch bar may be movably mounted on the frame and extend transversely between the first housing end and the second housing end in selective locked engagement with the first and second mounting slots to secure the mold assembly to the housing.

Claims (33)

1. An ice making assembly for a refrigerator appliance defining a vertical direction, a lateral direction, and a transverse direction, the ice making assembly comprising:

a housing defining a receiving chamber in fluid communication with an air duct, the housing extending transversely from a first housing end and a second housing end, the housing defining a first mounting slot at the first housing end and a second mounting slot at the second housing end; and

a mold assembly removably mounted to the housing, the mold assembly comprising:

a frame configured for receipt within the receiving chamber,

a heat exchanger mounted to the frame,

an ice mold supported on the heat exchanger and defining a mold cavity for receiving water, and

a latch bar movably mounted on the frame and extending transversely between the first housing end and the second housing end in selective locked engagement with the first and second mounting slots to secure the mold assembly to the housing.

2. The ice making assembly of claim 1 , further comprising a plurality of support tabs transversely spaced apart along the frame, the plurality of support tabs holding the latch bar on the frame.

3. The ice making assembly of claim 1 , wherein the latch bar comprises a rigid post horizontally slidable relative to the housing.

4. The ice making assembly of claim 1 , wherein the latch bar comprises a first rigid post, a second rigid post parallel to the first rigid post, and a compressible spring segment connecting the first and second rigid posts.

5. The ice making assembly of claim 4 , wherein the compressible spring segment comprises an M-shaped leaf spring.

6. The ice making assembly of claim 4 , wherein the compressible spring segment defines a first crest, and wherein the latch bar further comprises a first thumb hook extending outward from the first crest.

7. The ice making assembly of claim 4 , wherein the latch bar further comprises a guide sleeve within which the compressible spring segment and a portion of the first rigid post is received.

8. The ice making assembly of claim 1 , wherein the latch bar defines a pivot axis about which the latch bar is rotatable relative to the frame between a locked and an unlocked position within the first and second mounting slots.

9. The ice making assembly of claim 8 , wherein the housing further comprises a first C-shaped retention ridge extending about the first mounting slot and a second C-shaped retention ridge extending about the second mounting slot, and wherein the latch bar further comprises a first oval plug rotatably received within the first C-shaped retention ridge and a second oval plug rotatably received within the second C-shaped retention ridge.

10. A refrigerator appliance defining a vertical direction, a lateral direction, and a transverse direction, comprising:

a cabinet defining a chilled chamber;

a door being rotatably mounted to the cabinet to provide selective access to the chilled chamber;

an icebox mounted to the door and defining an ice making chamber; and

an ice making assembly positioned within the ice making chamber, the ice making assembly comprising:

a housing defining a receiving chamber in fluid communication with an air duct, the housing extending transversely from a first housing end and a second housing end, the housing defining a first mounting slot at the first housing end and a second mounting slot at the second housing end,

a frame configured for receipt within the receiving chamber,

a heat exchanger mounted to the frame,

an ice mold supported on the heat exchanger and defining a mold cavity for receiving water, and

a latch bar movably mounted on the frame and extending transversely between the first housing end and the second housing end in selective locked engagement with the first and second mounting slots to secure the frame to the housing.

11. The refrigerator appliance of claim 10 , further comprising a plurality of support tabs transversely spaced apart along the frame, the plurality of support tabs holding the latch bar on the frame.

12. The refrigerator appliance of claim 10 , wherein the latch bar comprises a rigid post horizontally slidable relative to the housing.

13. The refrigerator appliance of claim 10 , wherein the latch bar comprises a first rigid post, a second rigid post parallel to the first rigid post, and a compressible spring segment connecting the first and second rigid posts.

14. The refrigerator appliance of claim 13 , wherein the compressible spring segment comprises an M-shaped leaf spring.

15. The refrigerator appliance of claim 13 , wherein the compressible spring segment defines a first crest, and wherein the latch bar further comprises a first thumb hook extending outward from the first crest.

16. The refrigerator appliance of claim 13 , wherein the latch bar further comprises a guide sleeve within which the compressible spring segment and a portion of the first rigid post is received.

17. The refrigerator appliance of claim 10 , wherein the latch bar defines a pivot axis about which the latch bar is rotatable relative to the frame between a locked and an unlocked position within the first and second mounting slots.

18. The refrigerator appliance of claim 17 , wherein the housing further comprises a first C-shaped retention ridge extending about the first mounting slot and a second C-shaped retention ridge extending about the second mounting slot, and wherein the latch bar further comprises a first oval plug rotatably received within the first C-shaped retention ridge and a second oval plug rotatably received within the second C-shaped retention ridge.
