BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dew-prevention outlet device which can prevent moisture in the air from condensing at an air-conditioning outlet installed on a ceiling or a wall surface.

[0002]

2. Description of the Related Art Conventionally, in order to achieve air conditioning of an entire room or a predetermined place in a building, an air conditioning outlet is provided on a ceiling surface, a wall surface, or the like, and air conditioning is performed while blowing air from the air conditioning outlet. It is intended. The air-conditioning outlet is provided with a frame around the lower end portion of the outer frame of the cylindrical body, and the frame is brought into close contact with the lower surface of the air outlet inserted in the ceiling plate,
A duct connects the air-conditioning chamber installed above the ceiling and the upper end of the outer frame of the main unit with a duct to heat warm air in the vertical direction with respect to the ceiling surface during heating in winter and cool horizontally along the ceiling surface during cooling in summer. I'm blowing.

In the summer, the space above the ceiling becomes hotter and humid than the inside of the room. Water vapor in the humid air that is higher than the indoor side condenses on the surface and forms dew. To prevent this dew condensation, FIG.
As shown in FIG. 8, a heat insulating sheet such as glass wool is attached to the surface of the duct, the outer frame of the main body, or the front side of the frame facing the ceiling, or a heating element utilizing Joule heat is attached. To prevent condensation.

[Problems to be Solved by the Invention] However, the work of attaching and bonding a heat insulating sheet to the outer frame of the main body of the air-conditioning outlet or the surface side of the frame at the time of on-site construction is troublesome, and delays on-site work. A gap due to poor connection occurs between the insulation sheet attached to the outer frame of the main unit and the insulation sheet attached to the frame or the duct attached to the upper end of the outer frame. However, there is a disadvantage that air enters through the connection gap and dew condensation occurs. In addition, in the heating by the heating element, there is a problem that the equipment cost and the operation cost are easily increased.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to integrally form a heat insulating member capable of covering an outer surface including a frame portion from an outer frame of a main body of an air conditioning outlet, By covering this heat-insulating member with the air-conditioning outlet and tightly fitting it, it is not necessary to attach the heat-insulating member to the outer surface of the outlet, which simplifies on-site work and saves construction costs. It is an object of the present invention to provide a dew-condensing air outlet device that has no gap in a joint portion between an outer frame and a heat insulating member and a connecting portion between a heat insulating sheet on the outer surface of a duct and can prevent the occurrence of dew condensation.

[0006]

In order to achieve the above object, the present invention has an enlarged portion in one end side in the direction in which the air is blown out, which is continuous with the frame portion 16, and serves as the air blowing side. Air conditioning chamber 4 on the other end
The main body outer frame 12 has a cylindrical outer frame 12 having a connection portion (48) with the duct 2 and the duct 44, and an inner surface having substantially the same shape as the outer surface of the main body outer frame 12. It has a mounting opening 30 that can be fitted on the outer surface of the main body outer frame 12 by operation so as to cover the entire surface of the main body outer frame. And a heat-insulating member 14 in the form of a condensation.

Also, one or a plurality of air-impermeable films 37 are arranged in a sandwich shape inside the heat insulating member 14, and the heat insulating member 14 fits on the outer surface of the main body outer frame 12. It may be formed by compression molding into a shape.

[0008]

The dew condensation prevention outlet device according to the embodiment of the present invention is:
An integrally formed heat insulating member is closely fitted to the outer surface of the outer frame of the main body in the shape of a cover. Then, insert the outer frame of the dew-prevention blow-out device from the room of the blow-out opening opening into the ceiling plate into the back of the ceiling, join the frame portion to the lower surface of the blow-out opening, and install an air-conditioning chamber or the like installed behind the ceiling Is to connect.
Therefore, since the heat insulating member integrally formed from the frame portion to the upper end of the main body outer frame is tightly fitted in the form of a cover, there is no gap for air to enter the inner surface side of the heat insulating member, and the outside of the main body is cooled by the flow of cool air. Even when the frame or the frame is cooled, no condensation forms on the outer surface. In addition, the installation of the heat insulating member is simplified and the number of steps is not required, and the construction cost in the field work can be saved.
