Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an air conditioner provided with a drain hose and a drain pipe.

(B) Conventional Technology As a conventional technology of an air conditioner, there is one disclosed in Japanese Utility Model Publication No. 62-3626, in which an air conditioner main body having a heat exchanger and a blower is installed inside a ceiling. , A drain hose and drain pipe for discharging condensed water (drain) generated on the heat exchanger surface during cooling operation are connected airtightly with a hose band, and the drain hose and drain pipe are connected to prevent dew condensation on the drain hose and drain pipe. Insulation material for piping is wrapped around the pipe.

(C) Problems to be solved by the invention In the air conditioner described above, the work is completed by simply covering the drain hose and the drain pipe with a cylindrical heat insulating material and stopping with tape to save the work. The work of winding the tape in a spiral shape so as to press this heat insulating material against the drain hose and drain pipe from the top is very narrow inside the ceiling, and it takes a lot of work because it is at a high position,
Since this has not been done, the heat insulating material floats around the heat insulating material by the hose band from the drain hose and the drain pipe, and the air in the floating portion is cooled by the drain generated during cooling, and the drain hose and the drain pipe. It had the drawback that it would condense.

The present invention provides an air conditioner capable of preventing the dew condensation of the drain hose and the drain pipe without significantly increasing the labor of work.

(D) Means for Solving the Problems In order to solve the above-mentioned problems of the conventional technology, the present invention provides a drain hose for discharging the drain in the air conditioner,
A drain pipe connected to the drain hose; a hose band for connecting the drain pipe and the drain hose; and a heat insulating material for piping covering the hose band, the drain hose, and the drain pipe. In the present air conditioner, the hose band is covered with a soft heat insulating material, and the soft heat insulating material is covered with a heat insulating material for the pipe to form an air conditioner.

(E) Action In the air conditioner according to the present invention, since the flexible heat insulating material is interposed between the hose band and the heat insulating material for the pipe, the gap between the heat insulating material for the pipe and the drain hose and the pipe The flexible heat insulating material will be located in the gap between the heat insulating material and the drain pipe, and since the moist air cannot circulate on the surface of the drain hose or the drain pipe, the drain hose or the drain pipe will not be circulated. No condensation occurs on the surface.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional view of a ceiling-embedded air conditioner according to the present invention. (Five
0) is an air conditioner, which is inside the ceiling (1)
The air conditioner body (2) made of sheet metal to be housed in, the suction port (3) in the center, and the air outlets (4) on four sides of the outer peripheral part, and the ceiling hole (5)
A decorative panel (7) provided on the ceiling surface (6) so as to close the
It is composed of a suction grille (9) having an intake port (8) in the center.

(10) is a blower consisting of a turbo fan (11) and a fan motor (13) attached to the top plate (12), and (14) guides indoor air from the intake port (8) to the turbo fan (11). Nozzle mouth, (1
5) is a drain pan made of expanded polystyrene in an angular ring shape having an inner rising portion (15a) and an outer rising portion (15b), and (16) surrounds this fan on the discharge side of the turbo fan (11). It is a plate fin type heat exchanger arranged annularly.

And, (17) is a heat insulating material wound around the outer peripheral surface of the unit main body (2), (21) is a ventilation path for guiding the air heat-exchanged in the heat exchanger (16) to the outlet (4), (22) is a suspending bolt for fixing the air conditioner body (2) to the ceiling beam with the suspenders (23), (24)
Is a filter mounted on the downstream side of the suction grille (9).

Fig. 2 is a perspective view of the air conditioner main body, Fig. 3 is an explanatory view showing a connecting portion of the drain hose and the drain pipe, and (25) is a drain pan (15) and a pump (not shown) for pumping the drain. Drain hose communicating through, (26) is a drain pipe connected to this drain hose, (27) is a hose band for airtightly connecting the drain hose (25) and the drain pipe (26), (28) is a flexible and inexpensive urethane foam with heat insulating properties, and (29) is a pipe heat insulating material for pipes that has a notch in the axial direction. There is an adhesive tape (30) at the cut portion, and by stopping the heat insulating material with this tape, the heat insulating material (29) covers the drain hose (25) and the drain pipe all around.

In the air conditioner according to the present invention thus configured, the gap between the heat insulating material (28) near the hose band (27) and the drain hose (25), the heat insulating material (28) and the drain pipe (26), The urethane foam (28) will be placed in the gap, and the heat insulating material (2
Even if 9) is slightly lifted from the drain hose (25) or drain pipe (26) by the hose band (27), moist air cannot circulate in this gap, so the drain hose (25) or drain pipe (26) Condensation does not occur on the surface of).

Further, according to the present invention, a work requiring a great deal of work such as spirally winding tape so as to press the heat insulating material (29) for piping on the drain hose (25) or the drain pipe (26). Compared with the above, it is possible to obtain an effect substantially the same as that of performing the work of winding the tape in the spiral shape using urethane foam which is inexpensive and inexpensive.

(G) Effect of the Invention As described above, according to the present invention, it is possible to prevent dew condensation at the connection portion between the drain hose and the drain pipe by using an inexpensive material and without significantly increasing the labor of the work. There is a great effect.
