Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to the structure of an indoor unit of a separation type air conditioner, more specifically, an opening is formed on the back side of the main body base, and piping is provided through the opening. The present invention relates to an air conditioner that is derived.

“Prior Art” Conventionally, an indoor unit of a separation type air conditioner has an indoor heat exchanger 13 in an air flow path 12 formed in a main body base 11 as shown in FIG.
And a cross flow fan 14 are provided. In order to guide the pipe 15 of the indoor heat exchanger 13 to the outdoor side, the pipe 15 is drawn out through an opening 16 formed on the back side of the main body base 11, and the same opening 16 It was arranged along the recessed groove 17 connected to, and penetrated through the installation wall surface and led out to the outdoor side.

However, according to the conventional structure, since the opening 16 of the main body base 11 is left open, it is necessary to close the gap of the penetrating portion of the pipe 15 with a separate heat insulating component or the like.
Assembling is troublesome and takes a lot of man-hours, and there is a drawback that problems such as inflow of air into the main body base 11 and intrusion of foreign matter are caused from a defective assembly place.

[Problems to be solved by the invention] The present invention has been devised in view of the above-mentioned drawbacks of the conventional type, and when the piping is led out to the back side through the opening of the main body base, the opening of the main body is closed and pulled out. The present invention seeks to provide a structure for holding the sewage pipes.

"Means for Solving the Problems" As means for solving the above problems, the present invention is directed to an air conditioner in which an opening is formed on the back side of a main body base and a pipe is led out through the opening. On the back side of the main body base, a concave groove is formed which is connected to the opening and is used to embed the pipe. On the other hand, the opening and the concave groove are integrally formed with a lid for closing the opening and a holding piece for holding the pipe in the concave groove. The formed attachment parts are detachably attached.

[Embodiment] The present invention will be described below with reference to an embodiment shown in the drawings. In FIG.
An air flow passage 2 is formed in the air flow passage 2, and an indoor heat exchanger and a cross flow fan are arranged in the air flow passage 2. The above-mentioned chamber is provided on the back side of the side portion of the air flow passage 2. A square opening 4 for drawing out the pipe 3 of the inner heat exchanger is formed,
A concave groove 5 having a substantially U-shaped cross section with a required depth for burying the pipe 3 is integrally formed in the vertical direction continuing to the opening 4. On the other hand, the opening 4 and the groove 5 are covered with a lid 61 that closes the opening 5 by molding a heat insulating material such as synthetic resin.
Further, a holding piece 62 having a substantially U-shaped cross section for holding the pipe 3 in the groove 5, and a substantially T-shaped attachment component 6 having locking claws 63, 64 are integrally formed.

[Operation] With the above configuration, when assembling the air conditioner, the pipe 3 of the indoor heat exchanger is drawn out through the opening 4 on the rear side of the main body base 1, and the pipe 3 is bent downward. Groove 5
It is buried inside and its end is pulled out through the wall during the installation work. At the time of this piping work, the attachment component 6 is attached to the opening 4 and the concave groove 5 from the outside, and is fixed to the main body base 1 by the engagement of the locking claws 63 and 64, respectively. As a result, the opening 4 is closed by the lid 61 of the mounting component 6, and the pipe 3 in the groove 5 is integrally held by the holding piece 62 so as not to come out.

"Effect of the device" As described above, by forming the opening and the groove for guiding the piping on the back side of the main body base, and forming the mounting parts including the lid and the holding piece, it is possible to perform the piping work. It is possible to block the above-mentioned opening portion and simultaneously hold and fix the pipe embedded in the concave groove only by attaching the same attachment component.

As a result, unlike the conventional type, it is not necessary to individually close the gap between the penetrating portions of the piping of the opening of the main body base with separate heat insulating parts, etc., and the assembly can be simplified, and the number of assembly steps can be significantly reduced. In addition, it is possible to prevent the inflow of air into the main body base from the location of defective assembly, and it is possible to eliminate problems such as intrusion of foreign matter.
