PURPOSE:To prevent flying out of condensed water from a body without mounting a different part to an air guider by a method wherein the blade of a propeller fan is formed in a staged shape. CONSTITUTION:Since a pressure between an air guider 8 and a heat exchanger 11 on the outdoor side, i.e., the downstream side of blast, is higher than that on the upper stream side of blast, condensed water is blown out through the lower part of an orifice 14 of the air guider 8. In order that the condensed water is not scraped up by means of a blade 15 of a propeller fan 9, the blade 15 of the propeller fan 9 on the upper stream side of blast from a position making internal contact with the orifice 14 of the air guide 8 is formed in a staged shape 16. A shape is formed such that a case wherein, since a pressure on the upper stream side of blast from the lower part of the orifice 14 of the air guider 8 is lower than that on the downstream side, the condensed water is blown out and scraped up by means of the blade 5 of the propeller fan 9 is prevented from occurring, whereby water is prevented from flying out from a body 1. |
