Abstract

A refrigerator including an inner casing that is located within a main refrigerator body and that includes a storage compartment, and a mounting recess that is a recessed portion on a surface of the inner casing; and an in-refrigerator part s that is configured to be coupled to the inner casing and that includes: a temporary fixing protrusion that protrudes from a portion of the in-refrigerator part and that includes two segments that are configured to (i) be inserted into the mounting recess, (ii) be coupled to an inner portion of the mounting recess, and (iii) be fixed to the mounting recess is disclosed.

First claim

What is claimed is:

1 . A refrigerator comprising:
an inner casing that is located within a main refrigerator body and that includes:
a storage compartment, and
a mounting recess that is a recessed portion on a surface of the inner casing; and
an in-refrigerator part that is configured to be coupled to the inner casing and that includes:
a temporary fixing protrusion that protrudes from a portion of the in-refrigerator part and that includes two segments that are configured to (i) be inserted into the mounting recess, (ii) be coupled to an inner portion of the mounting recess, and (iii) be fixed to the mounting recess.

2 . The refrigerator of claim 1 , wherein each of the two segments of the temporary fixing protrusion includes:
a respective contact portion that is configured to be coupled to the inner portion of the mounting recess, wherein the inner portion of the mounting recess includes:
two pressure portions, each of the two pressure portions being configured to press a respective contact portion of the two contact portions, and
wherein the two contact portions are configured to become closer when the two segments of the temporary fixing protrusion are inserted into the mounting recess.

3 . The refrigerator of claim 2 , wherein, based on a determination of whether the two segments of the temporary fixing protrusion are inserted into the mounting recess, a first distance between the two contact portions is longer than a second distance between the two pressure portions.

4 . The refrigerator of claim 2 , wherein, based on a determination of whether the two segments of the temporary fixing protrusion are inserted into the mounting recess, a difference between a first distance and a second distance is smaller than a third distance between the two segments, and
wherein the first distance indicates a distance between the two contact portions and the second distance indicates a distance between the two pressure portions.

5 . The refrigerator of claim 1 , wherein the two segments of the temporary fixing protrusion include:
a first projection, and a second projection that faces the first projection, and wherein each of the first projection and the second projection includes:
a respective first portion that protrudes from the in-refrigerator part and that is spaced apart from the inner portion of the mounting recess,
a respective second portion that is pressed by the inner portion of the mounting recess, a circumference of the respective second portion is larger than a circumference of the respective first portion, and
a respective third portion that includes a first side and a second side, wherein a circumference of the respective third portion at the first side is larger than a circumference of the respective third portion at the second side.

6 . The refrigerator of claim 1 , wherein the two segments of the temporary fixing protrusion include:
a first projection, and a second projection that faces the first projection, wherein each of the first projection and the second projection includes:
a respective first sloping portion that protrudes from the in-refrigerator part and that includes a first side and a second side, wherein a circumference of the respective first sloping portion at the first side is smaller than a circumference of the respective first sloping portion at the second side, and
a respective second sloping portion that is coupled to the second side of the respective first sloping portion and that includes a third side and a fourth side, wherein a circumference of the respective second sloping portion at the third side is larger than a circumference of the respective second sloping portion at the fourth side, and
wherein a respective boundary portion between the respective first sloping portion and the respective second sloping portion is configured to be pressed by the inner portion of the mounting recess.

7 . The refrigerator of claim 1 , wherein the in-refrigerator part includes:
a base portion that is configured to support the temporary fixing protrusion, and through holes that connect a first side of the base portion to a second side of the base portion.

8 . The refrigerator of claim 1 , further comprising:
an outer casing that encloses the inner casing, and an insulation layer that is coupled between the outer casing and the inner casing and that is configured to block heat transfer from the inner casing to the outer casing.

9 . The refrigerator of claim 8 , wherein the mounting recess is configured to separate the storage compartment from the insulation layer.

10 . The refrigerator of claim 1 , wherein the mounting recess includes:
a stepped portion that protrudes from a surface of the mounting recess, and wherein the temporary fixing protrusion includes:
a bump that protrudes from the temporary fixing protrusion, and
wherein the stepped portion is coupled to the bump when the temporary fixing protrusion is inserted into the mounting recess.

11 . The refrigerator of claim 1 , further comprising:
a drawer that is configured to store food and that is moveable between a first position and a second position, the drawer being inside the storage compartment at the first position and a part of the drawer being outside the storage compartment at the second position, wherein the in-refrigerator part includes:
a sliding rail that is coupled to the inner casing and that is configured to guide the drawer.

12 . The refrigerator of claim 11 , wherein the sliding rail is coupled to a first of the drawer and includes a first temporary fixing protrusion that is configured to temporarily fix the sliding rail to the inner casing.

13 . The refrigerator of claim 1 , further comprising:
a vertical bar; and a bracket that couples the vertical bar to a surface of the inner casing and that is configured to divide the storage compartment into a first interior area and a second interior area, wherein the in-refrigerator part includes:
bracket holders (i) that couple the bracket to the inner casing and (ii) that are configured to support the bracket, each of the bracket holders including a respective second temporary fixing protrusion that is configured to temporarily fix each of the bracket holders to the inner casing.
