Description

[Detailed Description of the Invention] This invention relates to a ceiling-embedded air conditioner, and particularly relates to an improvement of a drain pipe connection device.

BACKGROUND ART In recent years, there has been an increase in the number of air conditioners that are installed in the ceiling and are used by arranging a plurality of them on the ceiling, and there are demands for reduced installation space and simplified services.

Conventionally, in order to satisfy these requirements such as reduction of installation space and simplification of service, there is an air conditioner that is vertical and thin, and occupies a small ceiling area, so that it can be serviced from the bottom of the air conditioner.

In this case, the piping and wiring to be connected to the air conditioner should be installed nearby in advance in the ceiling, and the connecting piping and wiring should be installed after the air conditioner is suspended from the ceiling opening so that it fits into the ceiling. Since the drain pipe is connected to the heat exchanger, water pressure is not applied to the drain pipe used to process the condensate generated from the heat exchanger, and the condensate is simply discharged due to the piping slope, creating an air pocket in the middle of the pipe. It has become extremely difficult to carry out piping work in a manner that prevents the occurrence of air pollution, and the generation of air pockets makes draining impossible, resulting in drawbacks such as overflowing from the drain pan inside the main body.

This invention was made with the aim of eliminating such drawbacks.

Hereinafter, this invention will be explained in detail with reference to the illustrated embodiment. Reference numeral 1 denotes an air conditioner main body, and a hanging bolt 4 which is suspended and fixed to a ceiling slab 3 in the attic 2, and this hanging bolt 4
It is suspended and supported by an adjustment hanging bolt 6 and a hanging fitting 7 which are fixed to the body through a connecting plate 5.

The main body 1 has a heat exchanger 8 in the upper part, a drain pan 9 below the heat exchanger 8, a filter 12 in the blower 10 and the blow-off opening 11, and is arranged in the opening 14 of the ceiling 13. There is.

Reference numeral 15 denotes a drain outlet connected at one end to the drain pan 9 of the main body 1, 16 a water inlet/outlet connected to the water heat exchanger (not shown) of the main body 1, and 17 an existing water pipe. A flexible connecting pipe 18 made of synthetic resin or the like and a connecting pipe 19 made of vinyl chloride or metal are connected to the water inlet/outlet 16 of the
It is connected by connecting.

20 has one end connected to the existing drain pipe 21 installed together with the existing water pipe 17, and the other end connected to the flexible joint pipe 1.
8 is a connecting pipe connected to the drain outlet 15 of the main body 1, and is suspended together with the connecting pipe 19 of the water pipe 17 by a hanging fitting 23 whose one end is fixed to a hanging bolt 22 hanging from the ceiling slab 3. Supported.

Reference numeral 24 designates an air vent thin tube vertically connected to the drain connecting tube 20, and its tip is bent into an inverted U shape, and the drain water level is lower than the drain water level stored in the drain pan 9 of the main body 1. It is always placed at the top.

To describe the installation order of the drain pipe connection device of the air conditioner configured as described above, the air conditioner main body 1 is raised to the attic space 2 through the opening 14 of the ceiling 13 using the power of a lift or the like.

Then, it is suspended and supported by a hanging fitting 7 that has been installed in advance.

Next, the connecting pipe 19 which is suspended and supported by the hanging fitting 23 and whose one end is connected to the existing water piping 17 is connected to the water inlet/outlet 16 on the main body 1 side through the flexible connecting pipe 18 .

Finally, the connecting pipe 20, which has one end connected to the existing drain pipe 21 and the air vent thin tube 24 facing upward, is connected to the drain outlet 15 on the main body 1 side through a flexible joint pipe 18. The drain pipe connecting device according to this invention can be obtained by fixing the connecting pipe 20 to the hanging fitting 23 so that the tip of the air vent pipe 24 is always above the predetermined water level stored in the drain pan 9 on the main body 1 side. It is something.

As mentioned above, this idea connects the drain outlet of the air conditioner main body and the existing drain pipe with a flexible joint pipe and a connecting pipe, and suspends the connecting pipe in the ceiling using a hanging fitting. Since the connecting pipe for the drain pipe is equipped with an air vent thin tube, even if an air pocket occurs inside the drain pipe, the air can be reliably removed by the air vent thin tube.
In addition, since the tip of the air vent tube is formed into an inverted U shape, dust enters the drain line through the tip opening of the air vent tube, preventing the drain line from being blocked by dust.
It has great practical effects, such as preventing the drain pipe from overflowing from the drain pan due to the generation of dust and air pockets, and preventing the ceiling from becoming dirty.
