In a ceiling-suspended air conditioner provided with a receiving unit for receiving a command signal from a wireless remote controller in the air conditioner main body, a projecting portion projecting downward in an installed state is formed on a bottom panel of the air conditioner main body. The receiving unit is installed on the protruding portion, and a receiving window of the receiving unit is provided to be inclined forward with respect to the air conditioner main body in the installed state.

According to a second aspect of the present invention, in a ceiling-suspended air conditioner provided with a receiving unit for receiving a command signal from a wireless remote controller in the main body of the air conditioner, the bottom panel of the main body of the air conditioner is recessed. The receiving unit is installed on the rear surface portion of the recess, and the receiving window of the receiving unit is provided to be inclined forward with respect to the air conditioner main body in the installed state. It is.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the receiving unit is installed near a suction grill on a bottom panel of an air conditioner main body.

The invention described in claim 1 or 2 has the following operation.

[0010] A receiving unit is installed in a protruding portion or a concave portion formed on a bottom panel of the air conditioner main body, and a receiving window of the receiving unit is inclined forward with respect to the installed air conditioner main body. Because of the provision, the receivable area of the receiving unit can be set so as to be inclined forward from the vertically downward direction with respect to the air conditioner body in the installed state. Therefore, even if the wireless remote controller is operated from a remote position on the front side of the ceiling-suspended air conditioner, the receiving unit can receive the command signal from the wireless remote controller. Signal receiving performance can be improved.

The third aspect of the invention has the following effects.

Since the receiving unit is arranged near the suction grill in the lower panel of the air conditioner main body, when the receiving unit is installed, the suction grill is opened, and the receiving unit is loaded through the opening covered by the suction grill. Since the worker can perform the electric wiring work around the receiving unit by attaching and inserting his / her hand through the opening, the installation work of the receiving unit can be simplified.
