Description

[Detailed description of the invention] The present invention relates to an improvement in the piping drawer structure of an indoor unit supported on a wall in a separate air conditioner.
One of the objectives is to greatly improve the workability of routing the pipes extending from the indoor unit and to prevent the refrigerant pipes from being exposed from the back of the main body.

Conventionally, the indoor unit of this type of air conditioner has a configuration in which the piping extends to the back of the indoor unit. The installed main unit must be lifted to the upper front or removed from the installation plate to connect the indoor/outdoor connecting pipes, assemble the parts, insulate the joints, etc., making the work extremely difficult and difficult to install. The work required more than 2 hours of manpower.

In addition, after the installation is complete, the piping is not completely straight, and there are some curved parts that protrude from the back of the indoor unit, allowing condensed water to adhere to the back of the indoor unit. There was a possibility of dripping from the protruding part onto the floor, and there were also aesthetic problems, such as the plumbing pipes appearing exposed when viewed from the bottom of the indoor unit.

The present invention eliminates the drawbacks found in the above-mentioned conventional air conditioners.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, A is the indoor unit main body of a separate air conditioner, and the underframe 1 is made of metal and serves as a water tray.
, a substrate 2 spot-welded to the water tray 1 and extending upward, a grille 3 attached to the underframe 1, and piping connected to a heat exchanger (not shown) constituting a well-known refrigeration cycle. It is equipped with 4th grade.

B is a part of the house, and is composed of a wall 6, a lintel 7, a ceiling 8, etc.

9 is attached to the upper and lower lintels 7 with screws or the like, and the plate 10 is fixed to the plate 9 with screws or the like.

The indoor unit main body A is installed by locking the locking piece 2b provided on the back side to the upper end of the plate 10.
It is rotatably supported around the center.

Here, a storage recess 2a is formed in the lower part of the substrate 2 over the gold mine, and the piping pipe 4 is inserted into the storage recess 2a.
It extends along the inside of a.

5. With the presser provided on the back of the indoor unit main body A,
It consists of a fixed piece 5a fixed to the back of the indoor unit main body A by welding or screws, and a holding piece 5b whose one end is rotatably attached to the fixed piece 5a, and the other end of this holding piece 5b is , is removably fixed to one end edge of the underframe 1 with a screw or an appropriate fitting structure.

This presser piece 5b rotates around the fulcrum 0.

In the above configuration, the plumbing pipe 4 of the indoor unit main body A
When connecting a pipe (not shown) from an outdoor unit (not shown), the indoor unit main body A is installed by supporting it on the plate 10 as shown in FIG. 3, and in this state, the indoor unit main body A is Rotate around the locking piece 2b, rotate the holding piece 5b of the holding tool 5 about 90 degrees, and install this holding piece 5b on the plate 1.
0 and maintains the indoor unit main body A in an inclined state.

In this case, if necessary, the plate 10 may be provided with a recess for locking the holding piece 5b.

As a result, a space for piping connection work indicated by S is formed at the back of the indoor unit main body A, and in this state, work such as connection of the piping pipe 4, installation, insulation, etc. can be performed.

Therefore, the work specifications are beautiful, the work can be done reliably and easily by one worker.

After the work is completed, by fixing the other end of the holding tool 5 to the lower part of the piping frame 1, it is possible to prevent the piping pipe 4 etc. from protruding from the back side.
Even if dew condensation occurs on the back surface and adheres to the piping pipe 4, etc., it can be prevented from dripping on the floor surface, and problems such as unsightliness due to exposure of the piping pipe 4, etc. after installation can be solved.

As is clear from the above embodiment, the piping drawer structure of the air conditioner according to the present invention is provided with a holding piece that rotates around one point on the back of the indoor unit main body. A work space can be created between the back of the indoor unit and the wall, and this space can be used to connect pipes quickly, beautifully, and reliably with just one worker, improving work efficiency. The scale is measured,
Furthermore, in the normal position of the holding piece, it is possible to prevent the connection pipe from being exposed from the back side of the indoor unit main body, and it is also possible to prevent condensed water from dripping onto the floor surface due to the protrusion of the connection pipe, which has various advantages.
