Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J This invention relates to a wall-embedded air conditioner that is installed within a wall.

[Prior Art] FIG. 11 is an exploded perspective view showing a first conventional installation device for a wall-embedded air conditioner disclosed in, for example, Japanese Utility Model Application Publication No. 59-195423.

In the figure, (1) is a wall of a room, and an installation frame (2) is embedded in the wall (1). (3) is the installation frame (2
) A wall-embedded air conditioner main body is housed and fixed in a wall-mounted air conditioner body, and a refrigerant pipe (4) of the main body is provided on the upper surface of the main body,
The air conditioner main body (3) is connected to the refrigerant connection pipe (5) at approximately the center of the upper part.

This refrigerant connection pipe (5) passes through the wall surface (1) and communicates with the outside of the room, and is connected to the outdoor unit (6) of the air conditioner. (7) is a drain pipe that connects to the air conditioner main body (3). The drain (8) generated by the water is guided outside (9).
is a front panel that closes the opening hole (lO) on the wall surface (1) and also closes the air intake port (11) of the air conditioner body (3).
and an air outlet (12), (1
31 is a drain pipe connection port. (14).

(15) is an inspection port and an inspection door provided at the bottom of the air conditioner main body.

Next, the operation of the first conventional example will be explained. First, the wall surface (1
) into the opening hole (lO) according to the outside dimensions of the installation frame (2).
will be established. Then, attach the installation frame (2) to this opening hole (10).
buried.

Next, insert and fix the air conditioner main body (3) into the installation frame [2], and connect the refrigerant connection pipe (5) and drain pipe (7) to the refrigerant pipe (4) of the air conditioner main body (3) and the drain pipe, respectively. Connect to the piping connection port (13).

At this time, if the drain piping (7) is installed horizontally, the drain piping (7) is fixed to a pillar (16) or the like with a saddle (17) to ensure the drain slope.

After closing the second inspection opening (14) with inspection R (15), the opening hole (lO) in the wall surface (1) is closed by attaching the front panel (9) to the air conditioner body (3). and complete the installation.

In addition, in the second conventional example, the object is to provide a wall-embedding device for a wall-mounted indoor unit that can basically be installed in a wall by introducing a general wall-mounted indoor unit.
There is something described in the No.

In addition, in the third conventional example, the external shape of the indoor unit main body and the opening between the passages are formed on the mounting wall surface, and steps are provided on both left and right sides, and the front panel is attached from the indoor side.

Japanese Utility Model Publication No. 14257/1983 discloses a configuration in which the front panel and the mounting wall surface are in the same plane.

[Problems to be Solved by the Invention] Conventional wall-mounted air conditioners are configured in one or more ways. Since there is no place to fix it, it must be fixed to a pillar etc. with a saddle, and because there is a distance from the drain pipe connection port to the position where the saddle is fixed, the drain pipe will sag due to its own weight, making it impossible to maintain a downward slope. There were problems such as drain overflowing from the drain tray.

In addition, simply inserting the air conditioner body into the installation frame will cause
Since the main body would not stabilize and fall forward, a series of installation work had to be performed after fixing one main body to the installation frame, which caused problems in installation workability.

In addition, steps must be provided on the left and right sides of the installation frame.
There is a problem in that by making the dimensions of the installation frame considerably larger than the dimensions of the air conditioner main body, the places where the air conditioner can be installed are slightly limited.

This invention was made to solve the above-mentioned problems when horizontally drawing the drain pipe.

To provide a drain drainage device for a wall-embedded air conditioner in which drain piping is reliably sloped downward and drain does not drip into a room from a drain tray.

It is also an object of the present invention to provide a wall-mounted air conditioner that can be installed in small spaces, and even in places where installation has not been possible before.

Another object of the present invention is to provide a wall-embedded air conditioner that facilitates a series of installation operations such as connecting refrigerant pipes.

[Means for Solving the Problems] The wall-embedded air conditioner according to the present invention is provided with an installation plate on the back side of the air conditioner main body, and a drain piping fixture is attached to the installation plate with an oblique slope. By fixing it, the drain piping can be reliably installed on a downward slope.

Further, there is a wall-embedded water air conditioner according to a second invention.

Both side plates are provided that protrude from the bottom of the housing and are formed in an L-shape and have flanges that receive the weight of the housing.

Further, the wall-embedded water air conditioner according to the third invention has grooves formed in the lower right corner and the lower left corner of the air conditioner main body, and a flange portion having a screw through hole on the front side of the groove, A flange portion having a fixing hole is formed at the lower part of both left and right side surfaces of the installation frame, and an L-shaped stopper is provided on the side surface.

[Function] In the wall-embedded water air conditioner of the first invention, when horizontally pulling the drain pipe, the drain pipe can be securely fixed to the installation plate with the drain pipe fixing device ensuring a downward slope. This prevents the drain piping from sagging or becoming trapped due to its own weight, and prevents the drain from overflowing from the drain tray and dripping into the room.

Further, in the wall-embedded water air conditioner according to the second invention, when the air conditioner main body is inserted into the installation frame, the main body does not fall forward, and work such as connecting refrigerant pipes can be performed.

Further, in the wall-mounted water air conditioner according to the third aspect of the invention, the air conditioner main body can be installed using an installation frame that is slightly larger than the air conditioner main body.
