Description

[Detailed explanation of the invention] (a) Industrial application field The present invention relates to a separate air conditioner that connects an indoor unit and an outdoor unit with piping.

(B) Prior Art Japanese Patent Application No. 108591/1987 is an example of a structure in which an outdoor unit of a separate air conditioner is equipped with a switching device that switches the refrigerant to a plurality of indoor units.

According to this content, the connection device (valve) disposed on one side of the outdoor unit and the switching device fixed to the other side were approximately at the same height.

(c) Problems that the invention aims to solve If the connection fittings of the outdoor unit and the switching device are at approximately the same height as described above, the piping connecting the fittings and the switching device, as well as the switching device and the indoor There was a problem in that the piping connecting the unit was concentrated in almost the same location, making it difficult to connect the piping.

(d) Means for solving the problem The air conditioner of the present invention has a connector installed on one side of the outdoor unit, and the refrigerant is installed on the other side that intersects with this one side at a different height from the connector. A fitting for a switching device is provided to switch the flow of water to a plurality of indoor units.

(e) Effect In the air conditioner of the present invention, when the switching device is attached to the outdoor unit, the connecting device of this unit and the switching device are misaligned, and the piping connecting the connecting device and the switching device and the switching device and the indoor The piping that connects the units is not concentrated in the same location but is distributed.

(F) Embodiment The drawing shows an embodiment of the separate air conditioner of the present invention, and 1 is an outdoor unit, which constitutes a part of two independent refrigerant circuits. The casing of this outdoor unit 1 is composed of a base 2, a wire guard 3, a back panel 4, an L-shaped cabinet 5, and two side plates 6 and 7. 8 is a rising edge formed on the outer periphery of the base 2, and 9 is this rising edge 8.
It is a connecting plate fixed to the corner of the

Reference numeral 10 denotes a plate-fin type heat exchanger bent into an L-shape, and is erected on the left side of the base 2.
Two independent refrigerant passages are formed in this heat exchanger. 11a and 11b are compressors, and the base 2
Connect each compressor 1 to the bolt 12 installed on the right side of the
The leg pieces 13 of 1a and 11b are inserted to support these compressors. 14 is a partition wall, and a heat exchanger 1 is installed inside the housing.
0 built-in heat exchange chamber 15 and compressors 11a, 11b
It is divided into left and right parts with a built-in machine room 16. The front flange piece 17 of this partition wall 14 has a front rising edge 18.
, the rear flange piece 19 is attached to the tube plate 20 of the heat exchanger 10.
are fixed to the front part 21 of each.

22 is a mounting base for the fan motor 23, and the upper end 2
4 into the upper edge 25 of the heat exchanger 10, and the lower end 2
6 is fixed to the raised portion 27 of the base 2. 28 is a blower fan connected to the shaft of the motor 23.

The rear panel 4 has a left flange piece 29 attached to the rear part 30 of the tube sheet 20 of the heat exchanger 10, and a right flange piece 31 attached to the rear part 30 of the tube sheet 20 of the heat exchanger 10.
is fixed to the connecting plate 9 as shown in FIG. A switching device is fixed to this back panel 4 at a position different in height from a valve to be described later.

The cabinet 5 constitutes the front plate and the top plate of the unit 1, and is bent into an L shape.
A blowout grill 33 is attached to the front. Then, the lower edge 34 of the front plate is fixed to the front part of the base 2, and the top plate is fixed to the upper end 24 of the mounting base 22, respectively.

The left side plate 6 has a suction port 35, and the right side plate 7 has a notch 36 for exposing the connection plate 9 and an outlet 37 for electrical components.

A heat exchanger 10 and a compressor 11 are mounted on the base 2.
After placing the components a and 11b and covering these devices with the cabinet 5, the both side plates 6 and 7 are applied from the sides and fixed.

The connecting plate 9 has a long piece 38 and a short piece 3 as shown in FIG.
The lower part of the long piece 38 and the lower part of the short piece 39 are spot welded to the rising edge 8, respectively. The long piece 38 has a raised portion 40.
is formed, and two sets of valves 4 are installed on this raised part.
1a and 41b are attached. These valves are connected to compressors 11a and 11b via piping. Connection port 42 of these valves 41a, 41b
a and 42b each face toward the rear of the unit in substantially the same direction as the raised portion 40. When the connecting plate 9 is fixed to the base 2 in this manner, the back panel 4 is in a state perpendicular to the long piece 38 of the connecting plate 9.

Reference numeral 43 denotes a casing attached to the rear panel 4, and this casing 43 has a built-in device for switching the refrigerant from the outdoor unit 1 to a plurality of indoor units (not shown). Reference numeral 45 denotes a refrigerant pipe led out from the lower part of the front surface 44 of the casing 43, which is bent into a substantially L-shape, with a connecting portion 46 at the tip facing upward. This connection portion 46 is connected to the connection port 42 of the valve 41a.
Connected to a. Reference numeral 47 denotes connection ports provided at the upper part of the front surface 44 of the casing 43, and the pipes (not shown) of the two indoor units are connected to these connection ports 47, respectively. Reference numerals 49 and 50 indicate attachment members attached to the left side surface 48.

Reference numerals 51 and 52 indicate attachments attached to the attachment portion 32 of the back panel 4.

When the housing 43 is attached to the outdoor unit 1, the lower mounting member 50 of the housing 43 is inserted between the back panel 4 and the lower mounting member 52 as shown in FIG. The upper part of the housing 43 is moved using the upper mounting member 49 as a fulcrum to bring the upper mounting member 49 into contact with the upper mounting tool 51, and these are fixed with screws 53. The lower mounting member 50 is also fixed to the lower fitting 52 with screws 54.

When the casing 43 is attached to the outdoor unit 1 in this manner, the pipe 45 led out from the casing 43 is located in front of the connection port 42a of the valve 41a. After that, when the piping 45 is rotated approximately 90 degrees toward the connection port 42a using the rising portion 55 as a fulcrum, the connection portion 46 of the piping 45 is connected to the valve 41a as shown by the broken line in FIG.
It is located in front of the connection port 42a of the connector, so that the two can be easily connected. In addition, since the height of the connection port 47 of the casing 43 and the height of the connection tool 41a are different from each other, the connection tools 41a, 41b of the outdoor unit 1 and the casing 43 are different from each other.
and the connection ports 47 are arranged in a vertical relationship. Therefore, the piping 45 extending from the casing can be shortened to ensure sufficient work space.

Note that in the above embodiment, the housing 43 is connected to the connector 41.
Although the outdoor unit 1 is equipped with two sets of connectors a and 41b, the present invention is not limited to this number of connectors; for example, the outdoor unit may be equipped with one set of connectors.

(g) Effects of the idea Since the outdoor unit's connectors and the switching device are placed at different heights, the pipes connected to the connectors and switching device can be distributed instead of being concentrated in the same location. This allows you to secure a large amount of work space.
