Abstract

A heat-insulation box, includes: a heat-insulation-box main body that has a space; a door that seals the space; and a partition plate that partitions the space, wherein the partition plate includes (i) a design plate that is placed at a side of the door, (ii) a first plate part and a second plate part that are each provided at both edges of the design plate, (iii) a heat-insulation material that is located in a region surrounded by the design plate, the first plate part, and the second plate part, and (iv) a heat-insulation member that is placed in at least one of a gap between the design plate and the first plate part, and a gap between the design plate and the second plate part.

Claims (28)

1. A heat-insulation box, comprising:

a heat-insulation-box main body that has a space;

a door that seals the space; and

a partition plate that partitions the space,

wherein the partition plate comprises (i) a design plate that is placed at a side of the door, (ii) a first plate part and a second plate part that are each provided at edges of the design plate, (iii) a heat-insulation material that is located in a region surrounded by the design plate, the first plate part, and the second plate part, and (iv) a first heat-insulation member that is placed only within a first gap defined by a first bent portion bent at a first end portion of the design plate and the first plate part, and does not protrude beyond an end of the first bent portion, and a second heat-insulating member that is placed only within a second gap defined by a second bent portion bent at a second end portion of the design plate and the second plate part, and does not protrude beyond an end of the second bent portion, and

wherein the first heat-insulation member and the second heat-insulation member are exposed at a front of the partition plate.

2. The heat-insulation box according to claim 1 , wherein the partition plate further comprises a heat-release part that is placed to be in contact with at least one of the first and second bent portions of the design plate.

3. The heat-insulation box according to claim 1 , wherein at least one of the first heat-insulation member and the second heat-insulation member is in a compressed state.

4. The heat-insulation box according to claim 1 , wherein the first plate part or the second plate part are only in contact with each other via the heat-insulation material.

5. The heat-insulation box according to claim 1 , wherein the heat-insulation material is surrounded by the at least one of the first and second heat-insulation members, the design plate, the first plate part, and the second plate part.

6. The heat-insulation box according to claim 1 , wherein the first plate part, the heat-insulation body, and the design plate are stacked.

7. The heat-insulation box according to claim 1 , wherein the first plate part, the at least one of the first and second heat insulation members, the design plate, and the heat-release part are stacked.

8. A heat-insulation box, comprising:

a heat-insulation-box main body that has a space;

a door that seals the space; and

a partition plate that partitions the space, wherein:

the partition plate comprises:

a design plate that is placed at a side of the door;

a first plate part and a second plate part that are each provided at edges of the design plate;

a heat-insulation material that is located in a region surrounded by the design plate, the first plate part, and the second plate part; and

a heat-insulation member that is placed in at least one of a gap between the design plate and the first plate part, and a gap between the design plate and the second plate part,

the heat-insulation member comprises a first fiber layer and a second fiber layer, which are made from only fibers without aerogel, and a composite layer including fibers and silica aerogel, and

the first fiber layer is provided on a first side of the composite layer and the second fiber layer is provided on a second side opposite to the first side of the composite layer, and wherein one of the first fiber layer and the second fiber layer is in contact with the design plate, the other of the first fiber layer and the second fiber layer contacts the first plate portion or the second plate portion.

9. The heat-insulation box according to claim 1 , wherein the design plate is U-shaped.

10. The heat-insulation box according to claim 8 , wherein the fiber layer is more deformable than the composite layer.

11. The heat-insulation box according to claim 1 , wherein an end surface of the first bent portion and the first heat-insulation member are flush with each other, and an end surface of the second bent portion and the second heat-insulation member are flush with each other.

12. The heat-insulation box according to claim 1 , wherein the first heat-insulation member is in contact with only one surface of the first bent portion, and the second heat-insulation member is in direct contact with only one surface of the second bent portion.

13. The heat-insulation box according to claim 8 , wherein the first fiber layer and the second fiber layer are made of a fiber material only.
