Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner divided into an outdoor unit and an indoor unit, in which the outdoor unit is installed on the back of a house or the like in a substantially close contact state. It is related to air conditioners.

BACKGROUND OF THE INVENTION In recent years, air conditioners have been installed in such a way that one indoor unit and one outdoor unit are installed as close to a wall as possible to maintain aesthetic appeal.

In particular, efforts have been made to mount not only indoor units but also outdoor units so that they can be placed as close to the wall as possible.

In such a situation, the piping connecting the outdoor unit and the indoor unit is required to be as short as possible.

In other words, if the length of the piping is sufficiently longer than the distance between the outdoor unit and the indoor unit, the extra length acts to widen the distance between the outdoor unit and the indoor unit due to the elasticity of the piping, and the wall surface This is because it goes against the intention of trying to get as close as possible to .

For this reason, reducing the length of the connecting piping as much as possible requires greater dimensional accuracy during installation, making it difficult to connect the piping, and ensuring sufficient space for the piping connection and work. Must.

Conventionally, the piping connectors in this type of air conditioner have generally been exposed from the outdoor unit.

Problems to be Solved by the Invention However, with this configuration, since the connecting tool is exposed, a sufficient working space can be secured, but on the other hand, there is a problem in that the aesthetic appearance is impaired.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to make it possible to shorten the length of connecting piping as much as possible without spoiling the aesthetic appearance, and to easily secure a working space for connecting the piping. It is something.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an opening in the lower part of the outdoor unit main body that spans at least two sides, a back surface and an adjacent surface, and a surface in this opening. A first surface having one end extending from the back side to the inside of the outdoor unit main body, and a first surface having the other end extending from the back side to the inside of the outdoor unit main body; an abbreviated fixing flange whose other end has a second surface extending from a surface adjacent to the rear surface within the outdoor unit main body so as to be perpendicular to the first surface; The first connector is fixed to the surface and has one end fixed to the discharge side and the suction side of the compressor, and a second connector, and the opened surface is connected to the opening. It is equipped with a removable cover that can be closed off.

With this configuration, the length of the connecting piping can be made as short as possible since it is connected at the back of the outdoor unit, and the opening is located at the bottom of the back so it is less noticeable and can be hidden behind the cover. In addition to being blocked, it does not impair the aesthetic appearance. Furthermore, since the opening extends across at least two sides, the two sides can be used as a space for inserting tools, etc. when connecting pipes, and work efficiency is not reduced.

EXAMPLE Hereinafter, the present invention will be explained with reference to the accompanying drawings showing one example thereof.

FIG. 2 shows the installation status of the air conditioner, in which 1 indicates an indoor unit and 2 indicates an outdoor unit.

Here, the indoor unit 1 and the outdoor unit 2 are fixed to a wall 3 of a house or an indoor ceiling 4 by means of well-known fixing means, respectively.
It is installed on the lower surface 5 of the balcony. The indoor unit 1 and the outdoor unit 2 are connected by connecting pipes 6, respectively. Also, inside the indoor unit 1, as is well known, there is a heat exchanger, a blower, etc. (none of which are shown).
The outdoor unit 2 is also equipped with a compressor, heat exchanger, blower, etc. that constitute a well-known refrigeration cycle (
(both not shown) are provided. These specific structures may be conventionally well-known structures and will not be described because they are not directly related to the gist of the present invention.

Next, the main structure of the outdoor unit 2 will be explained with reference to FIG. 1 and FIGS. 3 to 5.

In the figure, the outdoor unit 2 includes a board 11 and an outer box 12.
It also includes refrigeration cycle components, an air blower circuit, etc., which are arranged on the board 11 in a well-known manner. 13
is an opening that extends across three sides of the outdoor unit 2, including the back 12a, side 12b, and bottom 11m, and the opening 13 includes a closing surface 14a that closes the three sides;
A cover 14 including 14b and 14c is removably provided. The specific attachment/detachment structure includes a claw 14d inserted into the notch hole 12c of the outer box 12, and a screw 15 fixed to the bottom surface of the substrate 11 from the closed surface 14a. 16
is a fixed flange provided in the opening 13, one end of which extends inward from the rear surface 12m side and the first surface 16a and the side surface 1.
It is formed into an abbreviated shape with a second surface 16b orthogonal to the first surface 16m from the 2b side, and is fixed to the substrate 11 by appropriate means such as connection. 17 is a first connector fixed to the first surface 16m of the fixed flange 16; 18 is a second connector fixed to the second surface 16b of the fixed flange 16; By connecting the connecting pipe 6, a well-known refrigeration cycle is formed in a sealed manner.

Here, the first connector 17 and the second connector 18 are
As shown in FIGS. 4 and 5, their positions are set so that they are shifted by predetermined dimensions X, Y, and Z in the left-right direction, the up-down direction, and also in the front-back direction.

With the above configuration, the connection working space for the connection piping 6 in the outdoor unit 2 can be secured at 90° in both the horizontal and vertical directions, so that connection tools such as hexagonal wrenches can be inserted and rotated, for example. A wide range can be secured and work efficiency is improved. Also, the first connector 1
7. Since the positions of the second connectors 18 do not overlap in the vertical, horizontal, and front-back directions, one of the connectors may interfere with the rotation of the connecting tools, reducing the rotation range. do not have. In addition, since the opening 13 and the pipe connection part are both located closer to the back surface 12a of the outdoor unit 2, the length of the connection pipe 6 can be made as short as possible, and the connection direction is also the same as the direction in which the connection pipe 6 extends. Since the connection ports of the first and second connectors 17 and 18 are located, the indoor unit 1 can be pulled toward the wall 3, and the indoor unit 1
, it becomes possible to install both the outdoor units 2 close to the wall surface. Furthermore, since the opening 13 is closed by the cover 14, the aesthetic appearance is not spoiled. Also cover 1
4 can be attached and detached from the bottom of the outdoor unit 2, so there is no problem even if the outdoor unit 2 is installed as close to a wall as possible, and by simply removing the cover 14, the above-mentioned wide working space can be obtained. This will lead to further improvement in sexual performance.

Effects of the Invention As described above, the present invention provides an opening for connecting pipes at the lower part of the inconspicuous back of the outdoor unit main body.
The beauty of the outdoor unit is not spoiled, the length of piping from the indoor unit can be made as short as possible, and the underwater unit will not be separated from the wall due to excess piping length. Furthermore, since the opening is provided over at least the back surface and one other surface, a wide range of piping connection work space can be secured by removing the cover, making it easy to secure the work space.

In addition, the first and second connectors should be installed in positions where they do not overlap when viewed from the side and bottom of the outdoor unit main body, so that one connector does not obstruct the rotation range of the connection tool. This can also be prevented, and the workability of the layer can be improved.

Furthermore, by forming the opening across three surfaces, ie, the back surface, the side surface adjacent to this, and the bottom surface, the working space of the layer can be further expanded, and the cover has three surfaces opposite to the above three surfaces. Since the cover is shaped so that it can be screwed from the bottom, the cover can be attached and detached without any problem even if the outdoor unit main body is installed at a high place and in a corner.
