Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to an air conditioner.

(B) Conventional technology As a conventional technology for air conditioners, there is one described in Japanese Utility Model Publication No. 63-4897, in which the main body of the air conditioner equipped with a heat exchanger and a blower is installed inside the ceiling. In some cases, a panel having an outlet on each side is attached to the main body, and a louver for changing the direction of the blown air blown from the outlet is provided.

(C) Problems to be solved by the invention In the air conditioner, depending on the relationship between the ceiling and the living space,
In addition, the air conditioner may be located at a position displaced from the center of the ceiling due to the installation or removal of the walls that partition the floor.In this case, the louver blocks the air outlet farther from the center to control the temperature. The generated air is blown out toward the center of the room so that the air in the room has a temperature distribution as uniform as possible.

However, in the above-described air conditioner, the structure in which each louver individually blocks the air outlet is costly, and the work for assembling this structure is costly [time]. Further, since the louver cannot completely close not only the air outlet but also the air passage leading to the air outlet, cold air may leak to the inside of the ceiling through the gap, and it cannot be easily applied to an already installed air conditioner. There was also a drawback.

The present invention provides an air conditioner that is inexpensive and can be easily applied to existing air conditioners.

(D) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides air outlets on the lower surface of the main body of the air conditioner so as to blow out the air to the four surfaces of the air conditioner. A sealing material is provided for closing the ventilation passage near the outlet, a sealing material for sealing a gap between the sealing material and the air outlet, and a panel for pressing the sealing material are provided.

(E) Action In the air conditioner according to the present invention, an inexpensive material such as urethane foam can be used as the closing material, and a material such as foamed polyethylene can be used as the heat insulating material that serves as the sealing material. Can be provided. Further, since the air conditioner according to the present invention is provided with the sealing material that seals the gap between the blocking member and the air outlet, not only can the air passage near the air outlet be airtightly closed, but also the air conditioner assembly work can be performed. It's easy.

(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
Decorative panel (7) provided on the ceiling surface (6) so as to cover (5)
And a suction grill (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 the shape of a square ring having an inner rising portion (15a) and an outer rising portion (15b), and (16) installs this fan on the discharge side of the tarbon fan (11). The plate fin type heat exchanger, which is annularly arranged so as to surround it, (51) is a wall.

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 showing the relationship between the air conditioner body, the decorative panel, and the suction grill, and (25) is inserted into the ventilation passage (21) to show the air outlet (4a) and the ventilation passage (21). Blocking material made of urethane foam to be blocked, (26) is this blocking material made of urethane foam (25)
A sealing material made of expanded polyethylene attached to seal the gap between the air outlet and the air outlet (4a), and (27) is a screw for attaching the decorative panel (7) to the air conditioner body (2).

In the ceiling-embedded air conditioner of the present invention configured as described above, the conventional air conditioner such as the air conditioner having the structure in which each louver individually blocks the air outlet described in the section of the related art is used. In comparison, it is possible to seal the air outlet (4a) and the ventilation passage (21) in an airtight manner using an inexpensive material such as urethane foam or polyethylene foam, and the inside of the ceiling (1) from the gap of the air conditioner body (2). )
It is possible to avoid the leakage of cooling to the utmost.

Further, the urethane foam blocker (25) is inserted into the air outlet (4a) to block the air outlet (4a) and the ventilation passage (21), and the polyethylene seal material (26) is used as the urethane foam. The sealing material (25) is made of urethane foam, and the sealing material (25) is made of urethane foam, and the air outlet (4a) is airtightly connected to the sealing material (26). Assembling work of the air conditioner is very easy because it is only necessary to screw the decorative panel (7) to the air conditioner body (2) with screws (27) so as to press it against the body.

In addition, the present invention can be easily applied to an existing air conditioner without modifying the existing air conditioner.

The urethane foam used as the blocker in the present invention is made larger in size in advance, so it is also used in common for other outlets (4) and ventilation passages (21) that have a different shape from the outlet (4a). There is also an advantage.

(G) Effect of the Invention As described above, according to the air conditioner of the present invention, it is possible to hermetically close the ventilation passages leading to the air outlet and the air inlet with the inexpensive material and the easy assembling work. it can. Therefore, according to the present invention, it is possible to provide an air conditioner in which the cold air is prevented from leaking to the inside of the ceiling from the gap of the air conditioner and the dew condensation on the inside of the ceiling is prevented as much as possible. In addition, the present invention can be easily applied to an existing air conditioner without modifying the existing air conditioner.
