Description

[Detailed Description of the Invention] The present invention relates to a box structure for an integrated air conditioner that is installed on the wall or window of a building.

A conventional integrated air conditioner will be explained with reference to FIGS. 1 and 2.

4 bases are built into a box that is fixed to the window or wall of a building, and equipment such as 3 compressors, 6 indoor heat exchangers, and 5 outdoor heat exchangers are placed on the 4 bases. .

In order to condition the indoor air in an integrated air conditioner, the device body and the box must be installed so as to protrude indoors from the inner wall surface of the building or the inner surface of the window frame.

In such an air conditioner, drain water dehumidified by the indoor heat exchanger 6 and rainwater that enters through the outdoor air intake port 13 and the outdoor air discharge port 12 located inside the outdoor grille 11 are
It is led to the box body through the hole at the bottom of the 4-base, and is temporarily collected on the bottom plate of the 2-box body, before being discharged from the drain port provided in the box body.

In conventional air conditioners, the bottom plate of the box body does not have indoor and outdoor partitions, so drain water and rainwater are collected in the bottom metal body of the box body.

That is, since water is also stored in the box bottom plate 2 that protrudes indoors from the inner wall surface of the building and the inner side surface of the window frame, the box bottom plate is cooled by the water, and a large amount of water is collected on the lower surface d of the box bottom plate that protrudes indoors. There is a serious drawback in that frosting occurs and drips, which seriously stains interior walls, floors, and furniture such as rugs, and there has been a strong desire to improve this problem.

In order to improve the above-mentioned drawbacks, the present invention provides a partition across the entire width of the box bottom plate so that drain water and rainwater can be directed and drained only to the outdoor side bottom plate separated by the partition.

The present invention will be explained below with reference to an embodiment shown in FIGS. 3 and 4.

In FIG. 3, the interior of the box bottom plate is divided into an indoor side and an outdoor side by eight partitions that span the full width of the two box bottom plates.

4 is a base on which indoor and outdoor heat exchangers, a compressor, etc. are mounted as in the conventional example.

In addition, an outside air intake port and an outdoor air discharge port are provided in the outdoor grill 11.

The drain water that is dehumidified by the indoor heat exchanger when the air conditioner has this structure and the rainwater that enters from the outside air intake port and outdoor air outlet provided on the outdoor grill 11 are drained from the water drain provided at the base. It is led through the hole to the outdoor side separated by the partition 9 of the box bottom plate, and is discharged from the outdoor side drain port 14 provided on the back side of the box bottom plate, so that the indoor wall is discharged from the building inner wall surface of the box bottom plate. No water comes to the part d that protrudes inward.

On the other hand, in buildings such as buildings, there is a strong demand for drains to be installed indoors, under the floor, etc., instead of installing drains on the outside of the building, as emphasis is placed on the appearance of the building.

For this purpose, a gutter 9 is connected to the partition 8 provided on the bottom plate of the box body.
, the partition and the gutter are at almost the same height, and the outdoor side of the box bottom plate partition is connected to the indoor side drainage port.

In addition, a weir is provided on the outdoor side from the indoor side drainage port inside the gutter to drain drain water dehumidified by the indoor heat exchanger and rainwater that has entered from the outdoor air intake port and outdoor air outlet from the indoor side. Open the weir and plug the outdoor outlet.

Furthermore, when draining water from the outdoor side, by keeping the weir closed, water can be drained from either the indoor side or the outdoor side.

In addition, by providing a space between the bottom of the gutter that communicates with the indoor drainage port and the box bottom plate, and creating a heat insulating layer e, condensation will not form at the bottom of the gutter on the box bottom plate.

Generally, in an integrated air conditioner, a box is fixed to a wall or a window frame of a building, and the air conditioner main body is inserted into the box from the indoor side to establish continuity.

In the present invention, the top flange of the partition at the bottom of the box is shaped to face the outdoor side, making it easier to slide the air conditioner main body into it.

Furthermore, a heat insulating material 17 is provided at the part of the outdoor box bottom plate 2 that joins to the partition.
Since it is attached 2 to 4 mm higher than the partition, when water is drawn out from the drain hole provided in the base to the box body, it prevents water droplets from coming around from the bottom surface of the base and adhering to the top flange of the partition.

Since the height of the top flange of the gutter and the partition are approximately the same, the gutter can also serve as a rail for inserting and mounting the equipment body into the box, reducing the number of parts.

This invention has a partition that separates the inside of the box bottom plate into the indoor side and the outdoor side, which drains drain water and rainwater that enters from the outside air inlet and outdoor air outlet, and drains it only to the outdoor box bottom plate. Therefore, there is no condensation at all on the bottom plate of the indoor box, so it does not stain furniture such as wall and floor rugs.

Furthermore, by opening and closing the weir installed inside the gutter connected to the partition on the bottom plate of the box, the drainage direction of dehumidified water can be changed indoors or outdoors without removing the main body inserted into the box. have
