Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a ceiling recessed air conditioner in which an air conditioner is embedded in the corner of a descending ceiling provided by dropping a step into the ceiling wall of a building. Relating to a harmonizing device.

(B) Prior Art Japanese Utility Model Publication No. 49-37388 proposes a structure in which a ceiling hole is provided at the corner of a descending ceiling and an air conditioner is suspended and fixed in the ceiling space facing through the ceiling hole. However, with this installation structure, the air conditioner is installed so that the front and bottom parts of the outer box that form the air conditioner body are exposed indoors in a state that is similar to the ceiling hole. If the air conditioner is housed in the ceiling space through the ceiling hole, the ceiling hole will be blocked by the air conditioner itself, and the connection between the cold and hot water pipes and drain pipes that run through the ceiling space and the heat exchanger and drain pan inside the air conditioner will be blocked. It had the disadvantage of being difficult to work with.

Moreover, since the air conditioner is positioned so that it is schematically aligned with the ceiling board, the height of the drain pan cannot be set much higher than the ceiling board, and if the drain pipe that discharges outdoor sludge is longer than the drain pan, the drain slope will increase. There was a problem where the drain could no longer be drained smoothly.

For this reason, attempts have been made to create a structure in which the air conditioner is suspended and fixed in the depths of the ceiling space away from the ceiling hole, as in Japanese Utility Model Publication No. 53-1246, but it is difficult to determine the hanging position of the air conditioner. Since holes in the ceiling must be made separately in the horizontal and vertical parts of the ceiling, cutting out the holes in the ceiling is troublesome.In addition, since the corners of the downward ceiling remain, it is difficult for workers to cut out the ceiling space from the ceiling hole. When leaning inside to secure the hanging equipment and connect the hot and cold water pipes and drain pipes, it got in the way and hindered work.

(C) Purpose of the Invention The present invention facilitates the work of embedding the air conditioner in the ceiling, connecting the external piping, and the service inspection work, while also making it possible to easily determine the hanging position of the air conditioner. The purpose of the present invention is to provide a ceiling-embedded air conditioner that can discharge air without any trouble.

B) Structure of the Invention The present invention provides a ceiling hole in the corner of a ceiling plate installed in a stepped manner on the ceiling wall of a building, and an air conditioner is suspended and fixed in the ceiling space facing through the ceiling hole. In a built-in air conditioner, a blow-off duct is installed at the front air outlet of the air conditioner.
A suction duct is connected to the bottom suction port so that it can be expanded and contracted in the vertical direction, and a connecting device that allows both the outlet and suction ducts to expand and contract in the vertical direction is fixed across between the two ducts,
The ceiling hole is closed with an L-shaped decorative board, which is attached so that the air outlet grille on the curved surface part communicates with the air outlet duct, and the suction grille on the bottom part communicates with the suction duct. As a result, the air conditioner with the blowout duct and suction duct assembled can be easily pushed into the ceiling space through the ceiling hole, and the worker can hang the air conditioner by leaning into the outer periphery of the pushed air conditioner through the ceiling hole. After adjusting the height of the air conditioner, the tip of the suction duct should be placed on the same plane as the horizontal plane of the ceiling plate, so that it can be easily fixed to the fixture and connected to cold/hot water piping and drain piping, and to ensure the drain slope. When lined up, the air outlet ducts are also moved together by the connector, and the hanging position of the air conditioner relative to the ceiling hole is determined, and both the air outlet and suction ducts are connected.

The outlet communicates with both the outlet and intake grilles of the L-shaped decorative board. Furthermore, by removing the decorative panel, servicing of equipment within the air conditioner and repairs and inspections around the piping around the outer periphery of the air conditioner can be easily performed.
