It is preferable to have a second inclined surface 154a that is inclined toward the front toward the .

The second inclined surface 154a is formed to be inclined toward the front as it goes downward from the rear surface of the rear guide duct 154, and the front end of the second inclined surface 154a is provided so that a condensate drain port 1541a is located, the rear guide duct ( 154) When the condensed water falling from the inside flows along the upper surface of the second inclined surface 154a, it is preferable that the condensed water be easily guided to the condensed water drain port 1541a.

That is, the second inclined surface 154a is provided at the lower portion of the rear guide duct 154, and the rear guide duct connecting portion 1545 extending toward the front is provided at the lower end of the rear guide duct 154, as shown in FIG. As described above, the longitudinal cross-sections of the rear guide duct 154 , the second inclined surface 154a and the rear guide duct 154 may be formed in an approximately 'J' shape.

In this way, the condensed water formed in the rear guide duct 154 is guided to the condensed water drain 1541a by the first inclined surface 1549 and the second inclined surface 154a, so that it is quickly discharged to the outside through the condensed water drain 1541a.

As above, preferred embodiments of the present invention have been described in detail with reference to the drawings. The description of the present invention is for illustrative purposes, and those of ordinary skill in the art to which the present invention pertains will understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention.
