Description

[Detailed Description of the Invention] The present invention relates to an improvement of a piping device for a vertical air conditioner.

Conventionally, this type of piping device has been shown in FIG.

In the figure, 1 is a vertical air conditioner installed on the floor of each floor, and has an inlet 2 and an outlet 3.

4 is a heat insulating material 4a installed exposed on the rear surface of the air conditioner 1.
The air conditioner 1 is connected to the piping, which has undergone dew-proofing work and passes vertically through the floor surface.

Reference numeral 5 denotes a heat exchanger, which is connected to the pipe 4 through branch pipes 6 a and 6 b. The indoor air sucked from the suction port 2 is heat-exchanged by the heat exchanger 5 , and the hot or cold air is transferred to the blower 7 . Air is blown from outlet 3.

Reference numeral 8 denotes a drain pan for receiving condensed water from the heat exchanger 5, and is connected to a drain pipe (not shown) through a drain branch pipe 9.

In the piping device configured as described above, the piping 4 is connected to the air conditioner 1.
Not only does it spoil the aesthetic appearance because it is exposed indoors, but it is also difficult to carry out dew prevention work in narrow spaces.

In addition, connecting the pipe 4 and the branch pipes 6a and 6b is extremely troublesome.
It was particularly difficult to seal the gaps in air conditioners where branch pipes had penetrated.

The present invention was developed to eliminate the above-mentioned drawbacks of the conventional system, and it improves the aesthetic appearance of the room by passing the piping into the air conditioner and draining condensed water from the drain pan to the drain piping. The purpose of the present invention is to provide a piping device that is improved and eliminates the need for piping dew prevention work.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.

In Fig. 2, 21 is an air conditioner installed on the floor 22 of each floor, and 23 is a pipe that vertically penetrates and connects the air conditioners on the upper and lower floors through a pipe hole 22a that penetrates the floor. It is.

In FIGS. 3 and 4, 24 is an inlet of the air conditioner 1, 25 is an outlet, and 26 is a heat exchanger,
Indoor air taken in from the suction port 24 is heat-exchanged by the heat exchanger 26, and the hot or cold air is sent to the blower port 25 by the blower 27.
Air is blown from.

Of the pipes 23, 23a and 23b are main pipes that supply the medium to the heat exchanger 26, and branch pipes 28a, respectively.

It is connected to the heat exchanger 26 via 28b.

Also, 23C is a drain pipe.

29 is a heat exchanger 26 and main pipes 23 a and 23 b
This drain tray 29 is connected to the drain pipe 23 with a drain branch pipe 30.
Connected to C.

In FIGS. 5 and 6, the drain pan 29 has a through hole 31 through which the main pipes 23 a and 23 b and the drain pipe 23 C pass, and a flange 32 rises around the through hole 31 .

A main pipe and a drain pipe are held through bushings 33 attached to this flange 32.

As a result, all of the condensed water in the main pipes 23 a and 23 b and the drain pipe 23 C is received by the drain pan 29 and is discharged through the drain branch pipe 30 to the drain pipe 23 C.

As described above, according to the present invention, the main piping and drain piping are arranged inside the air conditioner, and the condensed water from the heat exchanger and piping inside the machine is received and discharged by the drain pan. The piping inside the conditioner no longer requires dew-proofing work, and the connections between the piping and the heat exchanger can be made inside the machine, so there is no need to drill through holes for branch pipes in the air conditioner or seal the gaps, as in the past. Not needed at all.

In addition, there is an effect that the aesthetic appearance of the room can be improved because the pipes are not exposed indoors.
