Abstract

Refrigerator casings and joint members therefor are provided. A joint member includes a body extending between a first end and a second end generally along a lateral direction. The body further includes a forward face and an aft face spaced apart from the forward face along a transverse direction, and further includes a top surface and a bottom surface spaced apart from the top surface along a vertical direction. The joint member further includes a plurality of barrier channels defined in the body, each of the plurality of barrier channels extending generally along the lateral direction between the first end and the second end. The joint member further includes a plurality of tube channels defined in the body, each of the plurality of tube channels extending generally along the vertical direction between the top surface and the bottom surface.

First claim

What is claimed is:

1. A refrigerator casing, comprising:
a main casing body, the main casing body comprising a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a top wall extending between the first sidewall and the second sidewall;
a casing bottom connected to the main casing body, the casing bottom comprising an upper flange extending generally along the lateral direction between the first sidewall and the second sidewall;
a back wall connected to the main casing body, the back wall comprising a lower flange extending generally along the lateral direction between the first sidewall and the second sidewall; and
a joint member comprising a body extending between a first end and a second end generally along the lateral direction, the joint member connected to the upper flange and the lower flange, the body comprising a top surface, a bottom surface, a forward face, and an aft face, and wherein a plurality of barrier channels are defined in a linear array in the aft ace between the top surface and the bottom surface, each of the plurality of barrier channels extending generally along the lateral direction between the first end and the second end, wherein the joint member further comprises a first protrusion extending from the body at the first end and a second protrusion extending from the body at the second end, the first protrusion disposed within a first pocket defined in the casing bottom, the second protrusion disposed within a second pocket defined in the casing bottom.

2. The refrigerator casing of claim 1 , wherein the joint member is formed from a plastic.

3. The refrigerator casing of claim 1 , wherein the casing bottom and the back wall are each formed from a metal.

4. The refrigerator casing of claim 1 , wherein a plurality of tube channels are defined in the body of the joint member, each of the plurality of tube channels extending generally along a vertical direction between a top surface and a bottom surface of the joint member.

5. The refrigerator casing of claim 4 , wherein the joint member further comprises a plurality of snap assemblies, each of the plurality of snap assemblies aligned with one of the plurality of tube channels.

6. The refrigerator casing of claim 1 , wherein the lower flange comprises a main plate and a hook plate cantilevered from the main plate generally towards a body of the back wall, and wherein the joint member comprises a plurality of tabs, and wherein a cantilevered end of the hook plate of the lower flange contacts the plurality of tabs to connect the back wall and the joint member.

7. The refrigerator casing of claim 1 , wherein the joint member further comprises a plurality of bosses, each of the plurality of bosses extending generally along the transverse direction.

8. The refrigerator casing of claim 1 , further comprising a machinery compartment cover plate connected to the casing bottom and the joint member.

9. The refrigerator casing of claim 1 , wherein the joint member further comprises a plurality of hooks.

10. The refrigerator casing of claim 9 , wherein each of the plurality of hooks extends from a top surface of the joint member.

11. A refrigerator casing, comprising:
a main casing body, the main casing body comprising a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a top wall extending between the first sidewall and the second sidewall;
a casing bottom connected to the main casing body, the casing bottom comprising an upper flange extending generally along the lateral direction between the first sidewall and the second sidewall;
a back wall connected to the main casing body, the back wall comprising a lower flange extending generally along the lateral direction between the first sidewall and the second sidewall; and
a joint member comprising a body extending between a first end and a second end generally along the lateral direction, the joint member connected to the upper flange and the lower flange, the joint member comprising a first protrusion extending from the body at the first end and a second protrusion extending from the body at the second end, the first protrusion disposed within a first pocket defined in the casing bottom, the second protrusion disposed within a second pocket defined in the casing bottom.

12. The refrigerator casing of claim 11 , wherein a plurality of tube channels are defined in the body of the joint member, each of the plurality of tube channels extending generally along a vertical direction between a top surface and a bottom surface of the joint member.

13. The refrigerator casing of claim 12 , wherein the joint member further comprises a plurality of snap assemblies, each of the plurality of snap assemblies aligned with one of the plurality of tube channels.

14. The refrigerator casing of claim 11 , wherein the lower flange comprises a main plate and a hook plate cantilevered from the main plate generally towards a body of the back wall, and wherein the joint member comprises a plurality of tabs, and wherein a cantilevered end of the hook plate of the lower flange contacts the plurality of tabs to connect the back wall and the joint member.

15. A refrigerator casing, comprising:
a main casing body, the main casing body comprising a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a top wall extending between the first sidewall and the second sidewall;
a casing bottom connected to the main casing body, the casing bottom comprising an upper flange extending generally along the lateral direction between the first sidewall and the second sidewall;
a back wall connected to the main casing body, the back wall comprising a lower flange extending generally along the lateral direction between the first sidewall and the second sidewall, wherein the lower flange comprises a main plate and a hook plate cantilevered from the main plate generally towards a body of the back wall; and
a joint member comprising a body extending between a first end and a second end generally along the lateral direction, the joint member connected to the upper flange and the lower flange, wherein the joint member comprises a plurality of tabs,
wherein a cantilevered end of the hook plate of the lower flange contacts the plurality of tabs to connect the back wall and the joint member.

16. The refrigerator casing of claim 15 , wherein a plurality of tube channels are defined in the body of the joint member, each of the plurality of tube channels extending generally along a vertical direction between a top surface and a bottom surface of the joint member.

17. The refrigerator casing of claim 16 , wherein the joint member further comprises a plurality of snap assemblies, each of the plurality of snap assemblies aligned with one of the plurality of tube channels.
