DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to an outer wall structure of a building where a wall-through type air conditioner is installed.

BACKGROUND ART As shown in FIG. 5, a wall-through air conditioner 1 (hereinafter referred to as an air conditioner) is installed on an indoor floor and along the indoor side of a waist wall 2 (outer wall) of a building. The air supply port 3 and exhaust port 4 of the air conditioner 1 introduce and exhaust outside air through communication passages 5 and 6 for air supply and exhaust provided in the waist wall 2. There is (actual equity 1-252
(See Publication No. 24).

The outdoor end of the communication path 5 is opened to the outdoors as a lower introduction of outside air, and the outdoor end of the communication path 6 is opened to the outdoors as a discharge port 8, and the indoor end is connected to the air supply port 3 and the exhaust port 4 of the air conditioner. Connection ports 9 and 10 are provided.

In this case, the air supply port 3 and exhaust port 4 of the air conditioner 1 are usually
Since it is formed at the upper part of the back of the air conditioner 1, the communication passages 5, 6, the lower introduction of outside air, and the outlet 8 are also formed at the waist wall 2 at a position corresponding to the upper part of the air conditioner 1. There is. As a result, the communication passage 5.6 becomes nearly horizontal as shown in the figure, making it easy for raindrops to enter from the outside air intake lower and exhaust port 8 to the respective connection ports 9.10 (and rainwater entering the air conditioner 1). , rainwater may seep out from the connection points between the waist wall 2 and the air conditioner 1.

In addition, it is generally difficult to form the communication paths 5 and 6 in the waist wall 2 itself due to construction reasons, and when forming them on the horizontal frame material placed on the top surface of the waist wall 2 as shown in FIG. but,
Since this is the part where the waist wall 2 and the opening 11 at its upper part meet, many work steps are required.
Workability is not improved that much.

Furthermore, with the above structure, the entire air conditioner 1 is disposed protruding toward the indoor side of the waist wall 2, so the indoor space is narrowed accordingly.

Problems to be Solved by the Invention An object of the present invention is to provide an outer wall structure that prevents rainwater from penetrating to the indoor end of a communication passage provided for supplying and exhausting an air conditioner.

Measures to solve the problem: Install outside air inlets and outlets below the air conditioner in front of the outer wall of the building.

Connect the outside air inlet and outlet on the outer wall to the air supply and exhaust outlet of the air conditioner through communication passages.

The communication passage has a structure that includes an indoor/outdoor direction portion leading to the outside air inlet and exhaust port, and an up-down direction portion leading to the air conditioner's air supply port and exhaust port.

Rainwater is prevented from reaching the indoor end of the communication path by arranging the inlet and outlet of the working outside air in front of the outer wall and below the air conditioner.

The communication path connects the air conditioner to the outdoor side, allowing outside air to be introduced into and discharged from the air conditioner.

Embodiment In the embodiment, the building outer wall 16 is constituted by the panel body 12, and the panel body 12 and the wall-through type air conditioner 1
A wall panel unit 13 is formed by (first and second
figure).

As shown in FIGS. 1 and 3, the panel main body 12 extends vertically around the slab (floor) 15 position of the frame 14 to form a spandrel part 17 of the building outer wall 16, and the upper half becomes the waist wall 2. There is.

The panel body 12 is composed of a rectangular frame 18 and upper and lower outer panels 19 and 20 attached to the outdoor sides of the frame 18, as shown in FIG. The communication path forming frame 21 is fixed in the lateral direction. The communication passage forming frame 21, as its cross section is schematically shown in FIG. It is 5°6. The air supply communication passage 5 and the exhaust communication passage 6 are separated by a partition wall (not visible in the figure) that crosses the above-mentioned interval so that the air flows on both sides do not mix.

Note that FIG. 1 shows a portion of the air supply communication passage 5. The exhaust communication passage 6 has the same structure except that the direction in which the outside air flows is reversed.

Connection ports 9 and 10 are provided on the top surface of the upper member 23 to connect to the air supply port 3 and the exhaust port 4 of the air conditioner 1, respectively.

When the upper and lower outer panels 19.20 are attached to the frame 18,
Since the frame body 18 has the dimensions in the projected direction, a space 24.25 is formed on the indoor side of the outer panel 19.20, and an outside air intake lower and an exhaust air opening in the front are formed between the upper and lower outer panels 19.20. An outlet 8 is formed (FIG. 3).

The communication passage 5.6 has an outside air introduction/discharge lower part 8 that opens at the front of the panel body 12, and a connection port 9.10 at the indoor end that opens toward the bottom of the air conditioner 1. It is provided with an indoor-outdoor direction portion a connected to the outside air introduction lower and an up-down direction portion a connected to the connection port 9.10.

In FIG. 2, reference numeral 26 is a tight material for the communication passage forming frame 21.
It is attached around the connection port 9.10 formed on the top surface of the.

The panel body 12 connects the indoor side surface of the frame body 18 to the outer wall 16.
It is fixed to the outdoor side surface of the frame 14 in close proximity to the indoor reference plane m (FIG. 1).

The air conditioner 1 is a wall-through type air-source heat pump type air conditioner, and has an outside air supply port 3 and an exhaust port 4 on the bottom surface, and the vertical dimension h1 width dimension W is smaller than each of the above-mentioned upper spaces 24. Reference numeral 27 indicates an air outlet toward the indoor side.

As is well known, in this type of air conditioner 1, the circulation path of outside air and the circulation path of indoor air are in contact with each other via a heat exchanger, and the direction of operation is reversible, so that both cooling and heating can be performed. It is possible to do it.

When the building frame 14 is completed, the outer wall 16 is constructed using a curtain wall method. At this time, the wall panel unit 13 according to the present invention is used for the spandrel portion 17, and as shown in FIG. The vertical position is adjusted and fixed to the frame 14 using various connecting fittings 28.

The height of the waist wall 2 is determined according to the height h of the air conditioner 1 combined with this panel body 12.

At this time, in the illustrated embodiment, the upper surface of the communication passage forming frame 21 almost coincides with the upper surface of the slab 15, so that the connection ports 9 and 10 on the communication passage forming frame side and the air supply/exhaust port of the air conditioner 1 will be described later. 3
, 4 can be directly connected by simply interposing the tight material 26, but when the communication passage forming frame 21 is lower than the upper surface of the slab 15, a connecting duct (not shown) is prepared and the upper end A tight material is provided on the slab 15.
Keep it at about the same height as the top surface of.

Next, the air conditioner 1 is hung from the indoor side into the above-mentioned upper space 24 of the panel main body 12, and the air supply/exhaust ports 3 and 4 on the bottom of the panel body 12 are hung.
are connected to the connection ports 9 and 10 of the communication path forming frame 21, respectively, and fixed to the frame 14 and the panel body 12. Therefore, the air conditioner 1 is installed so as to fit into the dimension of the panel main body 12 in the projected direction and protrude toward the outdoors from the indoor reference plane m of the outer wall 16 of the building. In addition, the outside air introduction lower of the panel body, the exhaust port 8, the air supply port 3 of the air conditioner 1, and the exhaust port 4
are connected to each other by communication passages 5.6 and communicated with the outdoors. The introduction lower of the communication passage 5.6 and the discharge port 8 are connected to the air conditioner 1.
It will be located further down.

In FIG. 1, reference numeral 29 denotes a decorative top plate, which is used to improve the appearance of the upper surface of the air conditioner 1 and the lower frame portion of the opening 11 on the indoor side.

By combining the panel body 12 and the wall-through type air conditioner 1 into a wall panel unit in this way, the outer wall of the spandrel section 12, which is provided with the waist wall 2 and on which the wall-through type air conditioner 1 is arranged, can be made into a wall panel unit. Easy to configure.

In addition, the assembled air conditioner 1 from the indoor side looks as shown in Fig. 4, in combination with the panel main body 12.
The amount of protrusion toward the indoor side will be small. As a result, the livability of the indoor space is improved.

When the air conditioner 1 is driven, the outside air introduced from the introduction lower part of the panel body 12 passes through the air supply passage 5 and reaches the air supply port 3 of the air conditioner 1, where it is mixed with indoor air inside the air conditioner. After heat exchange, the air is discharged outdoors from the exhaust port 8 via the exhaust port 4 and the exhaust communication path 6. During this time, the air inside the room is circulated separately, and cold or warm air resulting from heat exchange with the outside air is discharged into the room from the outlet 27.

At this time, if it is a rainy day, raindrops will enter from the outside air intake lower part of the panel body and the exhaust 808, but since the communication passages 5 and 6 are both vertical parts at the points leading to the connection ports 9 and 10, Rainwater that has entered will not reach the connection port 9.10 at the end.

In addition, the introduction lower part of the panel body 12 and the outlet 8 are connected to the air conditioner 1.
Since it is provided further down, if necessary, the drain stored inside the air conditioner 1 can be allowed to flow down naturally into the communication path 5.6.

The above are examples.

The panel body may be made of PC concrete.

Furthermore, the present invention may be applied to parts of the outer wall structure other than the spandrel parts.

Effects of the Invention Due to the structure of the communication passage for introducing and discharging outside air, rainwater does not enter the indoor side of the air conditioner panel body or the inside of the air conditioner.
