(Prior Art) In general, a ceiling-embedded air conditioner is provided with a heat exchanger inside the air conditioner main body, and a drain pan is provided below the heat exchanger. A decorative board having an inlet and an outlet formed on each side is attached, and the indoor air sucked in from the inlet is heat-exchanged by the heat exchanger, and is blown out from the outlet toward the indoor side. Furthermore, when condensate is generated in the heat exchanger during cooling operation, the condensate is caught by the drain pan.

When a predetermined amount of drain is stored in the drain pan, it is necessary to discharge the drain to the outside of the air conditioner main body. Disclosed in Publication No. 61-110821, etc., and
The structure is shown schematically in the figure.

That is, a drain pump 8 is provided on the drain pan 7, a discharge port 8a of the pump 8 is raised upward along the side wall of the air conditioner main body 1, and this raised end is connected to the side wall of the air conditioner main body 1. A drain pipe 9 having an insulating structure is connected to the projecting end to prevent condensation from forming on the pipe surface and wetting the ceiling surface due to the low temperature drain flowing inside. The drain thus stored in the drain pan 7 is pumped up by the pump 8 and discharged to the outside via the drain pipe 9 from the discharge port 8a.

Incidentally, when installing the air conditioner, as shown in FIG. is attached to the ceiling board B, and the drain pipe 9 is arranged in the ceiling space S, and this pipe 9 is connected to the discharge port 8a of the pump 8 protruding from the side wall of the air conditioner main body 1.
