[Problems to be Solved by the Invention]

Since the conventional embedded air conditioner is configured as described above, it can be installed in the space of one span, but it cannot be installed in the space of three shaku, and the suction port is air-conditioned. Since it is located on the back of the machine body, in addition to the air on the inside of the room, it sucks in the air inside the ceiling through the gaps in the ceiling material, which causes problems such as inaccurate temperature detection.

In addition, the conventional embedded air conditioner, when performing service work such as inspection and maintenance, remove the installed drain pipe and refrigerant pipe, remove the main body once, and lower it from the ceiling or the inside of the bag to the floor. Since the service is performed from the top surface and the back surface of the main body, there is a problem that the work becomes troublesome.

Furthermore, in the conventional embedded air conditioner, materials such as sheet metal corresponding to the upper suction port and the rear suction port are wasted, and the strength around the upper suction port and the rear suction port is weak. There was a problem that the blower room of the main body was deformed or destroyed.

The embedded air conditioner of the present invention is made to solve the above-mentioned problems, and can be installed in one-span width and three shaku widths, and can also be installed in the ceiling. At the same time, the objective is to obtain an embedded air conditioner that enables accurate temperature detection and diversification of installation.

It also aims to enable service from the back side, top side, and bottom side of the air conditioner body, depending on the installation location.

Another object is to obtain an air conditioner that eliminates waste of materials, has improved strength, and is compatible with diversified installation forms.

[Means for Solving the Problems]

The embedded air conditioner according to the invention of claim 1 is attachable / detachable so that the suction ports provided on the upper surface, the lower surface, and the rear surface of the housing and the upper surface suction port and the lower surface suction port maintain a space and are covered. A suction duct and a melala plate that can close the upper suction port, the lower suction port, and the rear suction port can be attached to and detached from the upper, lower, and rear suction ports according to the installation condition of the housing. It was done.

Further, in the embedded air conditioner according to the invention of claim 2, an upper surface angle forming left and right and rear side end portions of upper surfaces of the heat exchanger chamber and the blower chamber, and an upper surface angle fixing the upper edge of the partition plate. A plurality of pieces, a lower surface angle forming the left and right sides of the lower surface of the blower chamber, a rear surface side end portion, a lower surface angle piece fixing the lower edge of the partition plate, and an upper surface angle and a lower surface angle integrally forming the blower chamber. The vertical angles of the above are fixed to each other by welding or the like to form the upper surface suction port, the lower surface suction port, and the rear surface suction port.
