BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner such as a ceiling mounted type.

[0002]

2. Description of the Related Art An example of a conventional air conditioner of this type is shown in FIGS. Inside the case body 2 embedded in the ceiling 1, a heat exchanger 7, a drain pan 10, a motor 5,
A blower 6, a baffle plate 12, and the like are built in. A ceiling panel 8 is attached to a lower portion of the case main body 2, a suction port 3 is formed at a central portion thereof, and an air outlet 4 is formed adjacent to the suction port 3.

During operation of the air conditioner, refrigerant from an outdoor unit (not shown) circulates through the heat exchanger 7, and the blower 6 is driven by the motor 5. Then, the room air in the room 9 is guided from the suction port 3 through the suction grill 11 and the filter 13, guided by the baffle plate 12, sucked into the blower 6 and urged.
Then, it is cooled or heated in the process of flowing through the heat exchanger 7 to be conditioned air and blown out of the outlet 4 into the chamber 9.

[0004] An insulation 14 for soundproofing, heat insulation and prevention of dew condensation is provided on the outer and inner surfaces of the case body 2. An outside air intake 15 is formed in the peripheral wall 2a of the case body 2. An outside air guide plate 16 formed by pressing a metal plate as shown in FIG. 5 is installed inside the case body 2 so as to face the outside air intake 15, and flanges 16 a on both side edges of the outside air guide plate 16 are provided. Is fixed to the inner surface of the peripheral wall 2a, the upper edge 16b is in contact with the surface of the insulation 14 stretched on the inner surface of the top plate 2b of the case body 2, and the lower edge is the outer wall of the drain pan 10.
It is in contact with the top surface of 10a. In this manner, the outside air guide plate 16 is provided inside the case body 2 by the outside air guide plate 16.
Are formed. One end of an outside air introduction duct 18 is fixed to the peripheral wall 2 a of the case body 2 so as to communicate with the outside air intake 15. The outside air is outside air introduction duct 18,
The air is drawn into the blower 6 through the outside air inlet 15 and the outside air duct 17, outside the drain pan 10 and below the baffle plate 12.

[0005]

In the above conventional air conditioner, the upper edge of the outside air guide plate 16 and the insulation
There is a risk that a gap is easily formed between the case body 2 and the surface of the case 14, and therefore, there is a possibility that cool air may leak from the gap and form dew on the case body 2. In addition, there is a problem that it takes time and effort to attach the outside air guide plate 16.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problems, and the gist of the present invention is that the above-mentioned case body faces an outside air intake formed in the case body. An air conditioner comprising an outside air guide plate forming an outside air guide passage inside the air conditioner, wherein the outside air guide plate is integrally formed by insulation integrally formed on the inner surface of the case body. Air conditioner.

[0007]

According to the present invention, when the insulation is integrally formed on the case body, the outside air guide plate is integrally formed by the insulation formed on the inner surface thereof.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS. Insulations 20a and 20b made of styrene foam or the like are integrally formed on the inner and outer surfaces of the case main body 2, and at the same time, the outside air guide plate 21 is integrally formed with the inner insulation 20b. Other configurations are the same as those of the related art shown in FIGS. 3 and 4, and corresponding members are denoted by the same reference numerals. The upper edge of the outside air guide plate 21 formed in this manner is connected to the insulation 20a on the inner surface of the top plate 2b, and both side edges are connected to the insulation 20b on the inner surface of the peripheral wall 2a. By contacting the upper end surface of the outer wall 10a of the drain pan 10 to the outside, the outside air guide passage 17 is formed inside the case body 2. Since both the upper edge and both side edges of the outside air guide plate 21 are integrally connected to the insulation 2a, no gap is generated between the outside air guide plate 21 and the case body 2, and therefore, There is no leakage of cold air.

[0009]

[Effects of the Invention] In the present invention, since the outside air guide plate is integrally formed by the insulation integrally formed on the inner surface of the case body, there is no gap between the outside air guide plate and the case body, so that the cool air leaks. The condensation of the case body 2 based on the above can be prevented. Also, unlike the related art, there is no need to attach the outside air guide plate to the case main body, so that the number of parts and the number of attachment steps are reduced, and the cost can be reduced.
