[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner, and more particularly, to an auxiliary pipe of a heat exchanger disposed in an air passage of the indoor unit at a rear side of a housing. Means for holding.

[0002]

2. Description of the Related Art The housing of an indoor unit of an air conditioner is:
It is composed of a main body and a front cover that is detachably mounted on the main body.A suction port is provided at the front of the front cover to take in indoor air, and the lower part sends out heat-exchanged air into the room. Outlet is formed.
In an air passage connecting the suction port and the air outlet, an air filter detachably provided near the suction port, a heat exchanger, and a blower (cross-flow fan) disposed below the heat exchanger. The air that has been heat-exchanged by the heat exchanger is sent out indoors by a blower. An auxiliary pipe for connecting to the refrigerant pipe from the outdoor unit side is previously connected to the heat exchanger of the indoor unit, and this auxiliary pipe is used when the heat exchanger is arranged in the air passage. It is made to protrude backward from an opening formed on the back side of the body, the tip is taken out from the side surface of the housing, and a pipe press is applied midway to fix the body to the back side of the housing.

[0003]

However, in the case of the above-mentioned indoor unit, since the heat exchanger and the pipe retainer must be separately mounted on the front side and the rear side of the main body, the heat exchanger must be mounted at a predetermined position. After fixing to the position, it is necessary to turn the main body half a turn or arrange another worker on the facing surface. As a result, the number of assembling steps is increased, and the mounting requires not only a pipe holder but also mounting screws and tools, which hinders cost reduction. Therefore, an object of the present invention is to provide an indoor unit of an air conditioner that solves these problems.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has an air passage connecting a suction port at the front or upper part of a housing and an air outlet at a lower part of the housing. In an indoor unit of an air conditioner, an auxiliary pipe from a heat exchanger disposed at a position protruding from the rear of the housing and a tip end thereof is taken out from a side surface of the housing. And a holding pipe for holding the pipe holding is provided inside the opening formed in the rear surface of the housing.

[0005]

According to the above construction, when the pipe retainer is mounted at a predetermined position of the auxiliary pipe and the heat exchanger is mounted at a predetermined position in the air passage, the pipe retainer is formed inside the rear surface of the housing in the process. The auxiliary pipe can be held on the back side without using screws or tools because it is fitted in the groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 is an external perspective view showing the front of the indoor unit, and FIG. 2 is a perspective view showing the rear of the indoor unit. In the figure, reference numeral 1 denotes a housing composed of a main body 2 and a front cover 3 detachably mounted on the main body 2. A front panel 4 is provided in front of the front cover 3 and has an upper part pivotally supported so as to be openable and closable.
The front panel 4 has a suction port 5 for room air, and a lower opening of the front cover 3 has an outlet 6 formed therein. An air passage (not shown) is formed between the suction port 5 and the air outlet 6, and a detachable air filter, a heat exchanger, and a blower (cross flow fan) are formed in the air passage. The air that has been heat-exchanged by the heat exchanger is sent to the outlet 6 by a blower, and the wind direction into the room is adjusted by a wind direction plate provided in the outlet 6.

The back (base) of the main body 2 shown in FIG.
An opening 9 is formed in 7 to allow an auxiliary pipe 8 from the heat exchanger to protrude behind. One side of the auxiliary pipe 8 is connected to the heat exchanger side in advance, and once the heat exchanger is disposed at a predetermined position in the air passage, the auxiliary pipe 8 once faces downward at the upper part inside the opening 9, After projecting to the outside, it is formed to face the side surface of the main body 2. by the way,
In the present invention, a pipe holder 10 separately formed on the auxiliary pipe 8 is mounted in advance. On the other hand, the opening 9 is provided with a holding groove 11 for holding the pipe retainer 10 inside the opening 9. Hereinafter, these details will be described with reference to FIGS.

The pipe retainer 10 is a resin molded product,
The main body portion 10a has a substantially U-shaped groove shape for holding the heat insulating tube 15 covering the refrigerant pipes 13 and 14, and has substantially lug-like flange portions 10b and 10c formed on both left and right side surfaces thereof. ing. On the other hand, the holding groove 11 has a wall 11a formed so as to surround the inside of the opening 9 provided on the back surface 7 of the main body 2, and a gate protruding from both sides of the opening 9 so as to narrow the frontage of the opening 9. The width dimension of the protruding walls 7a, 7b is slightly larger than the lateral width of the main body 10a of the pipe retainer 10. With such a configuration, when the auxiliary pipe 8 is moved in the direction of the arrow, the pipe retainer 10 and the holding groove 11 correspond to each other, and the pipe retainer 10 fits in the holding groove 11 as shown in FIG. At this time, the flanges 10b, 10
Since c faces the protruding walls 7a and 7b on the back surface 7 side, the pipe retainer 10 does not jump out to the opening side, and the auxiliary pipe 8 is securely held in the holding groove 11. In the present embodiment, one surface of the wall 11a is also used as the side wall 7b of the air passage 16 accommodating the heat exchanger 12 and the like, but is not necessarily limited to this.

[0009]

[Effect of the invention] If the indoor unit is a pipe holder as described above, which is attached to the auxiliary pipe from the heat exchanger, and a holding groove for holding the pipe holder is provided inside the opening at the back of the main body, Since the pipe retainer is easily fitted into the holding groove during the process of projecting the auxiliary pipe to the rear side, mounting screws and the like become unnecessary, the number of assembling steps is reduced, and the cost can be reduced.
