In this way, the sleeve pipe 32 is attached to the tubular portion 3
It fits in 0.

Further, 34 is the back side of the collar 31 and the cylindrical portion 3.
0 is a reinforcing rib formed so as to connect to the back side of the protective member 9 and the rib abuts against the peripheral wall of the wall hole 8 so that the protective member 9 is not easily displaced or slipped out of the wall hole 8.

Reference numeral 35 is a notch provided in the cylindrical portion 30, and 36 is a groove for facilitating the cutting off of the cutting portion 37. This groove is cut by a blade when the protective member 9 protrudes from an indoor unit described later. Is.

Reference numeral 20 denotes an indoor unit of a separation type air conditioner, which has a suction grill 21 at the upper front and a discharge port 22 at the lower front.
Are formed.

In FIGS. 4 and 5, reference numerals 23, 24 and 25 denote inter-unit piping, inter-unit wiring, and drain hose extending rearward from the rear surface of the indoor unit, all of which are the cylindrical portion 30 of the protective member 9 and the sleeve. It penetrates the pipe 32 and is guided to the outside of the room.

The inter-unit pipe 23 and the unit pipe wiring 24 are connected to an outdoor unit [not shown].

Reference numeral 38 is a putty for filling a gap on the outdoor side of the wall hole 8.

The indoor unit 20 is hooked on the hooking piece 26 of the back plate 3 and attached to the wall surface 2 in the room.

When the sleeve tube 32 is inserted into the wall hole 8 and fitted to the end portion of the sleeve tube so that the protection member 9 is applied to the sleeve tube 32, the tubular portion 30 of the protection member 9 comes into contact with the sleeve tube 32 from the outside and the stopper is provided. 33 hits the end of the sleeve tube 32 and hits from the outside of the sleeve tube 32.
The tubular portion 30 does not reduce the passage area of the pipe in the sleeve pipe 32, and the pipe 23, the wiring 24, the drain hose 2
It is easy to pass 5 through the sleeve tube 32 of the wall hole 8.

Further, since the passage of the pipe 23 in the sleeve pipe 32 is not narrowed, the passage of the pipe in the sleeve pipe 32 can be fully utilized, and the heat insulating material of the pipe 23 is crushed to easily cause dew condensation on the pipe 23. Can be prevented.

Since the passage area of the pipe is not narrowed in this way, a thick pipe of 4 minutes [4/8 inch] and a thick pipe of 2 minutes [2]
/ 8 inch] thin tube with 80 mm diameter wall hole that was previously formed for an indoor unit with a capacity of 4.0 KW, 3 minutes [3/8 inch] thick tube and 2 minutes [2 / 8 inch] thin tube and an indoor unit of 2.5 kW capacity or an indoor unit of 2.8 kW capacity may be set to the same diameter as the wall hole of 65 mm in diameter. Even if set to, it is not difficult to insert the pipe into the wall hole, and the heat insulating material of the pipe is not easily crushed.

For this reason, it is possible to use the wall hole having a diameter of 65 mm, which was used in the indoor unit having the capacity of 4.0 KW and the capacity of the indoor unit having the capacity of 2.5 kW or 2.8 KW, and the protective member 9 is set to 4 The one having the capacity of 2.5 KW and the one having the capacity of 2.8 KW can be used for the one having the capacity of 0.0 KW, and the parts can be commonly used.

Furthermore, since the protective member 9 is configured to be applied to the sleeve pipes 32, 32a from the outside, the tubular portion 30
It is possible to reduce the size without increasing the size of the pipe 23. In particular, as shown in FIG.
