PURPOSE:To prevent condensation on a substrate and also prevent staining the appearance of the window and wall of a chamber in which a device is installed by providing a groove for drain water route which starts at the drain water outlet 20 of a water receiving tray and reaches the lower section of the water receiving tray which is opposite to the rotational direction of a propeller fan 10 and an opening section at the lower section of an air guider. CONSTITUTION:A groove 8 of the drain water route which starts at the drain water outlet 20 of a water receiving tray and reaches the lower section of the water receiving tray which is opposite to the rotational direction of a propeller fan 10 and has an inclination with respect to a base 5 and a small opening section 14 at the lower section of an air guider 13 which is on the extension line from the groove 8 are provided. As a result, from the inclined groove 8 and the opening section 14 at the lower section of the air guider 13 the drain water flows smoothly without staying at one spot, and it is led to the lower section of the propeller fan 10 so that no condensation occurs on the base 5 because it is cooled with the cold drain water and there is no need to paste a heat insulating material on the base. And, it is possible to prevent staining the appearance of the window and wall of a chamber in which the main body is installed and damaging them. |
