Abstract

A refrigerator, according to one embodiment, includes an inner case with an improved structure. The inner case includes a plurality of plates forming faces of the inner case, and one or more frames disposed between the plurality of plates to support the plurality of plates. The plates and the frames may be molded separately, without being molded as one body, so that the plates and the frames can be formed with various materials.

First claim

What is claimed is:

1. A refrigerator comprising:
an inner case having an opening and defining a storage room accessible through the opening,
wherein the inner case comprises:
a plurality of plates forming faces of the inner case, the plurality of plates including at least three plates;
a plurality of frames, each disposed between two neighboring plates of the plurality of plates to support the two neighboring plates;
a plurality of joints disposed at a back part of the inner case to support the plurality of plates and the plurality of frames, each joint of the plurality of joints including
three first supporting grooves supporting three plates of the plurality of plates, respectively, such that corners of the three plates are inserted into respective supporting grooves of the three first supporting grooves, and
three second supporting grooves supporting three frames of the plurality of frames, respectively, such that end portions of the three frames are inserted into respective supporting grooves of the three second supporting grooves, each of the three second supporting grooves having an end that is in communication with two of the three first supporting grooves; and

a cover member disposed at a front part of the inner case around the opening to cover at least one frame selected from plurality of frames or at least one plate selected from the plurality of plates, the cover member including
a plurality of first supporting parts respectively supporting the plurality of plates disposed on a rear portion of the cover member, the plurality of plates being in contact with the plurality of first supporting parts, and
a plurality of second supporting parts protruded from the rear portion of the cover member, respectively supporting the plurality of frames, and including bent parts in contact with outer surfaces of the plurality of frames to support the plurality of frames.

2. The refrigerator according to claim 1 , wherein, for each of the plurality of frames, the frame comprises two insertion grooves to respectively receive the two neighboring plates of the plurality of plates so that the neighboring plates are supported by the frame.

3. The refrigerator according to claim 2 , wherein, for each of the plurality of frames, the two insertion grooves are at a right angle with each other.

4. The refrigerator according to claim 2 , wherein, for each of the plurality of frames,
the frame extends along a longitudinal direction of an edge, of one of the two neighboring plates, inserted into the frame, and
the two insertion grooves of the frame are formed along the longitudinal direction along which the frame extends.

5. The refrigerator according to claim 1 , wherein
the plurality of plates are among five plates included in the refrigerator,
the five plates include:
an upper plate and a lower plate respectively forming an upper part and a lower part of the inner case;
two side plates respectively forming both side parts of the inner case; and
a back plate forming a back part of the inner case,

the plurality of frames are among eight frames included in the refrigerator, and
the eight frames are respectively disposed between the upper plate, the lower plate, and the side plates to support the plurality of plates.

6. The refrigerator according to claim 5 , wherein the eight frames are respectively disposed between the upper plate, the lower plate, the side plates, and the back plate to support the five plates.

7. The refrigerator according to claim 1 , wherein
each frame of the plurality of frames further comprises an exposed part exposed to the inside of the inner case, and
the refrigerator further comprises a lighting device disposed on the exposed part of at least one frame of the plurality of frames.

8. The refrigerator according to claim 7 , wherein the lighting device is integrated with the at least one frame.

9. The refrigerator according to claim 7 , wherein the at least one frame on which the lighting device is disposed is located at an upper part of the inner case.

10. The refrigerator according to claim 1 , wherein the cover member comprises, on a rear part of the cover member:
a first supporting part into which the at least one plate selected from the plurality of plates is inserted and supporting the at least one plate; and
a second supporting part supporting the at least one frame selected from the plurality of frames.

11. The refrigerator according to claim 1 , wherein the cover member further comprises a flange part extending outward from the opening of the inner case to an outside of the inner case.

12. The refrigerator according to claim 1 , wherein, for each joint of the plurality of joints, the three first supporting grooves of the joint are formed at right angles with respect to each other.

13. The refrigerator according to claim 1 , wherein
at least one frame of the plurality of frames further comprises an exposed part exposed to the inside of the inner case, and
the exposed part has a concave curvature facing the inside of the inner case.

14. A refrigerator comprising:
an inner case defining a storage room,
wherein the inner case comprises:
a plurality of plates disposed to form faces of the inner case, the plurality of plates including at least four plates;
a plurality of frames, each connecting two neighboring plates among the plurality of plates to form corners between the plurality of plates, the plurality of frames including at least five frames; and
a plurality of joints disposed at a back part of the inner case to support the plurality of plates and the plurality of frames, each joint of the plurality of joints including
three first supporting grooves supporting three plates of the plurality of plates, respectively, such that corners of the three plates are inserted into respective supporting grooves of the three first supporting grooves, and
three second supporting grooves supporting three frames of the plurality of frames, respectively, such that end portions of the three frames are inserted into respective supporting grooves of the three second supporting grooves, each of the three second supporting grooves having an end that is in communication with two of the three first supporting grooves.

15. The refrigerator according to claim 14 , wherein
for each of the plurality of frames, the frame comprises two insertion grooves to respectively receive the two neighboring plates of the plurality of plates so that the neighboring plates are supported by the frame.

16. The refrigerator according to claim 15 , wherein, for each of the plurality of frames, the two insertion grooves are at a right angle with each other.

17. The refrigerator according to claim 14 , wherein
the plurality of frames are disposed between the plurality of plates at an upper part of the inner case, and
the plurality of frames disposed at the upper part of the inner case comprise a lighting device facing toward an inner part of the inner case.

18. The refrigerator according to claim 17 , wherein the lighting device is integrated with the plurality of frames disposed at the upper part of the inner case.

19. The refrigerator according to claim 14 , wherein the inner case further comprises a cover member disposed in a front part of the inner case to support the plurality of plates.

20. The refrigerator according to claim 19 , wherein a supporting part is formed in a rear part of the cover member to support the plurality of plates and the plurality of frames.
