DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separation type air conditioner in which a plurality of housings are connected by piping.

[0002]

2. Description of the Related Art This type of separation type air conditioner is, for example,
There is one described in JP-B-58-11533. In this publication, an indoor unit (housing) of an air conditioner is stored in a top bag of a bay window, and an outdoor unit (housing) is stored in a base bag of a bay window. And such an indoor unit is generally shown in FIG.
It has a structure as shown in FIG. Reference numeral 51 denotes a housing having a built-in indoor heat exchanger, from which a thick tube and a thin tube connected to the heat exchanger are led out. At the ends of these tubes, connecting tools 52 and 53 called nipples are formed. These fittings are fitted in grooves formed around them to restrict axial movement, and fixed fittings are fitted to the outer diameters of both the thick pipe and the thin pipe to restrict rotation. It is fixed with the metal fitting 55.

[0003]

In the above-described separation type air conditioner, the connecting members 52 and 53 for connecting the thick tube and the thin tube are fixed by the fixing bracket 55 for restricting the rotation. Cannot be simultaneously stopped, for example, when the thick pipe fitting 52 is inclined with respect to the thin pipe fitting 53, the fixing fitting 55 cannot be attached at the same time. After the adjustment, the fixing bracket 55 was attached again. For this reason, the workability is extremely poor on the line where the line work is performed, and the product sometimes flows on the line without completing the work.

[0004] The present invention provides a separation type air conditioner that can easily fix a pipe connector.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a plurality of housings, one of which has a heat exchanger and a wall extending from the heat exchanger and connected to a pipe from the other housing. In a separate type air conditioner including a pipe and a thin tube connector, and a fitting that fits into a groove formed in the connector, the one housing regulates rotation of the thick tube connector. A thick tube fixture having a regulating portion and a through-hole through which the thin tube connector rotatably penetrates is provided. The thin tube fixture has a regulating portion for regulating the rotation of the thin tube connector. It is the one with the tool attached.

[0006]

In this separation type air conditioner, the rotation of only the thick pipe connector is restricted by the thick pipe fixture. Then, a thin tube fixing member for restricting rotation of the thin tube connecting member is attached to the thick tube fixing member.

Reference numeral 4 denotes an auxiliary electrical box mounted on the left side of the electrical box. A blow frame 15 supports a flap 16.
Reference numeral 17 denotes a display provided on the right side of the blowout frame, on which operation lamps and the like are arranged. Reference numeral 18 denotes an L-shaped fixture attached to the right side plate and the left side plate of the outer box 8, and is attached to a lower portion of the attachment piece 19 fixed to the bay window 2.

Reference numeral 20 denotes an interunit pipe which is provided in the indoor wall on the right side of the bay window and is connected to the outdoor heat exchange unit (the other casing) 30. The interunit pipe is composed of a thick pipe 20a and a thin pipe 20b.

The large tube 20a is connected to a large tube connector (nipple) 21, and the small tube 20b is connected to a small tube connector 22 (nipple).

Reference numerals 21a and 22a denote grooves formed in the thick tube connector 21 and the thin tube connector 22, respectively. Reference numeral 23 denotes a fitting which fits into these grooves to regulate the movement in the axial direction, and has a screw hole 23a and a regulating portion 23b which fits into the groove. Numeral 24 denotes a metal fitting for a thick pipe, and a fitting 21 for a thick pipe.
A hexagonal opening (regulating portion) 24a along the outer diameter of the tube, a round opening (through hole) 24b larger than the outer diameter of the thin tube, a mounting flange 24c, and a screw hole 24d formed in the flange. Screw hole 24e provided above opening 24b
And The thick tube fixing tool 24 restricts the rotation of the thick tube connecting tool 21 and does not restrict the rotation of the thin tube connecting tool 22. A metal thin tube fixture 25 is attached to the thick tube fixture. The thin tube fixing device 25 has a hexagonal opening 25a (restriction portion) along the outer diameter of the thin tube connecting device 22, a fixing portion 25b fitted into the large tube fixing device, and a screw communicating with the screw hole 24e. Hole 2
5c are formed.

In the separated type air conditioner constructed as described above, the thick tube and thin tube connectors 21 and 22 are fixed in the following procedure.

First, the grooves 21 of the connecting tools 21 and 22
a, the mounting bracket 23 so that the regulating portion 23b fits into the
Are attached to the connecting tools 21 and 22. Then, the connector 22 for a thin tube is passed through the opening 24b, the connector 21 for a large tube is fitted into the opening 24a, and the flange 24c of the fixture 24 is fixed to the outer box 8 with a screw 31. Next, the thin tube connector 22 is passed through so as to fit into the opening 25 a of the fixing device 25, and the fixing portion 25 b is fitted to the large tube fixing device 24. Then, the fixing members 24 and 25 are fixed with the screw 32. Thus, the thick tube connector 21 and the thin tube connector 22 can be fixed to the outer box 8,
When the inter-unit piping 20 is connected, the connecting tool 21,
22 does not rotate.

In such a separation type air conditioner, the fixing work of the thick tube and thin tube fixing members 21 and 22 to the outer box 8 is usually performed on a line for performing a flow operation. For this reason, in the fixture as shown in the conventional example, since the thick tube and the thin tube must be fixed by the fixture at the same time, if the direction of the hexagonal connection between the thick tube and the thin tube is the same, Although it is possible to do so, it is extremely rare that the directions of the hexagonal connectors are aligned in this way, and it is often impossible to perform these operations simultaneously in a short time on a line where a flow operation is performed.

However, in this separation type air conditioner, the thick pipe connector 21 whose angle adjustment is more difficult (thick and hard to rotate) than the thin tube connector 22 is performed first, and the thick pipe connector 21 is fixed. The fixing of the thin tube connector 22 can be separately fixed. In addition, by fitting and fixing the thin tube fixture 25 to the large tube fixture 24, the thin tube can be positioned and fixed.
1 and the thin tube connector 22 can be easily and quickly fixed.
In addition, when fixing the pipe fitting, the angle adjustment of the thick pipe fitting 21 with the thick pipe fixing tool 24 and the angle adjustment of the thin pipe fitting 22 with the thin pipe fixing tool 25 are performed. Since it can be performed, the angle adjustment of the connecting tools 21 and 22 is also very easy.

[0017]

According to the present invention, there is provided a separate type air conditioner for a large pipe having a restricting portion for restricting rotation of a connecting member of the large pipe and a through-hole through which the narrow pipe rotatably penetrates. A fixing device is provided, and a thin tube fixing device having a restricting portion for restricting the rotation of the thin tube connecting device is attached to the thick tube fixing device. Therefore, the rotation of the large tube connecting device is restricted by the large tube fixing device. Then, when the thin tube fixing member that restricts the rotation of the thin tube connecting member is attached to the thick tube fixing member, the connecting member for the thick tube and the thin tube is fixed. In this way, after fixing the thick tube fittings whose angle adjustment is difficult, the thin tube fittings whose angle can be easily adjusted can be fixed. The work can be performed quickly and reliably even on the work line.
