Abstract

There is provided an air conditioner including an indoor unit having an indoor heat exchanger, an outdoor unit having an outdoor heat exchanger connected to the indoor heat exchanger through a refrigerant pipe, and an outside casing housing at least the outdoor unit and is attached to a building wall that partitions an outdoor space and an indoor space. The outside casing is fitted in a wall communication hole formed in the building wall and communicating between the outdoor space and the indoor space, and has an inside space in which the outdoor unit is capable of being disposed A thermal insulation material is disposed in the inside space, and the thermal insulation material at least includes a first thermal insulation portion that is disposed on a side of the outdoor space and a second thermal insulation portion that is disposed on a side of the indoor space.

First claim

The invention claimed is:

1 . An air conditioner that includes an indoor unit having an indoor heat exchanger, an outdoor unit having an outdoor heat exchanger connected to the indoor heat exchanger through a refrigerant pipe, and an outside casing housing at least the outdoor unit and is attached to a building wall that partitions an outdoor space and an indoor space, wherein
the outside casing that is fitted in a wall communication hole and has an inside space in which the outdoor unit is capable of being disposed, the wall communication hole being formed in the building wall, and the wall communication hole communicating between the outdoor space and the indoor space, the inside space is opened to the outdoor space, the outdoor unit is disposed in the inside space of the outside casing, a thermal insulation material is disposed in the inside space of the outside casing, the thermal insulation material at least includes
a first thermal insulation portion that is disposed on a side of the outdoor space, and
a second thermal insulation portion that is disposed on a side of the indoor space and is attachable and detachable, and
the first thermal insulation portion has a recess portion in which the second thermal insulation portion fits.

2 . The air conditioner according to claim 1 , wherein
provided that a direction perpendicular to a direction toward the indoor space from the outdoor space and an up and down direction as a top wall is upper is a right and left direction, the top wall forming an upper surface of the outside casing, the thermal insulation material extends in the right and left direction and has the right and left direction as its longitudinal direction, and the thermal insulation material is disposed on a lower side of the top wall.

3 . The air conditioner according to claim 2 , wherein
the top wall has a first top wall that is disposed in the indoor space and a second top wall that is disposed from the wall communication hole to the outdoor space when the outside casing is fitted in the wall communication hole, and the first thermal insulation portion and the second thermal insulation portion are disposed on a lower side of the second top wall.

4 . The air conditioner according to claim 1 , wherein
provided that a direction perpendicular to a direction toward the indoor space from the outdoor space and an up and down direction as a top wall is upper is a right and left direction, the top wall forming an upper surface of the outside casing, the recess portion is formed so that a dimension of the recess portion on the side of the indoor space is larger than a dimension of the recess portion on the side of the outdoor space in the right and left direction.

5 . The air conditioner according to claim 4 , wherein
a first wind-shielding material is provided between the first thermal insulation portion and the second thermal insulation portion.

6 . The air conditioner according to claim 1 , wherein
a space forming member forming a space between the outside casing and the thermal insulation material is disposed between the outside casing and the thermal insulation material.

7 . The air conditioner according to claim 1 , wherein
the first thermal insulation portion is divided into at least a first thermal insulation member and a second thermal insulation member, the first thermal insulation member has a first end surface that faces the second thermal insulation member, the second thermal insulation member has a second end surface that faces the first thermal insulation member, and the first end surface and the second end surface face each other.

8 . The air conditioner according to claim 7 , wherein
the first thermal insulation member has a first base portion and a first extension portion extending from the first base portion, the second thermal insulation member has a second base portion and a second extension portion extending from the second base portion, in an indoor and outdoor direction toward the indoor space from the outdoor space, a length of the first extension portion is shorter than the first base portion and a length of the second extension portion is shorter than the second base portion, and the first end surface is provided in the first extension portion and the second end surface is provided in the second extension portion.

9 . The air conditioner according to claim 7 , wherein
either one of the first end surface and the second end surface includes a pressing surface that applies a pressure toward the outside casing to an other of the first end surface and the second end surface, and the other includes an action surface that receives a press.

10 . The air conditioner according to claim 9 , wherein
the first thermal insulation member has a first base portion and a first extension portion extending from the first base portion, the second thermal insulation member has a second base portion and a second extension portion extending from the second base portion, a length of the first extension portion in a direction perpendicular to an indoor and outdoor direction toward the indoor space from the outdoor space is longer than a length of the second extension portion in the direction perpendicular to the indoor and outdoor direction, the first end surface includes the pressing surface, and the first extension portion in vicinity of the first end surface is provided with a fixing portion that fixes the first thermal insulation member to the outside casing.

11 . The air conditioner according to claim 9 , wherein
the pressing surface is formed to have an acute angle with respect to the outside casing when the first thermal insulation portion is disposed in the outside casing, and the action surface is formed to have an acute angle with respect to the outside casing when the second thermal insulation portion is disposed in the outside casing.

12 . The air conditioner according to claim 9 , wherein
the pressing surface is formed to be in parallel with the outside casing when the first thermal insulation portion is disposed in the outside casing, and the action surface is formed to be in parallel with the pressing surface formed in parallel with the outside casing when the second thermal insulation portion is disposed in the outside casing.

13 . The air conditioner according to claim 9 , wherein
a second wind-shielding material is disposed between the pressing surface and the action surface when the first thermal insulation portion is disposed in the outside casing.

14 . The air conditioner according to claim 13 , wherein
a cushioning member is disposed between the first thermal insulation portion and the outside casing, the cushioning member includes
a first cushioning member disposed between the first thermal insulation member and the outside casing, and
a second cushioning member disposed between the second thermal insulation member and the outside casing,
a part of the first cushioning member or a part of the second cushioning member is provided between the pressing surface and the action surface, and the part of the first cushioning member or the part of the second cushioning member provided between the pressing surface and the action surface becomes the second wind-shielding material.

15 . The air conditioner according to claim 14 , wherein
