作業を容易に行うことができる。On the other hand, when removing the heat exchange guard 15, the heat exchange guard 15 is pressed toward the center from the outer portion thereof, and the heat exchange guard 15 is slightly curved so that the outer shape is changed to the opening of the intake port 9. Pull out the upper part while making it slightly smaller than the part 9a. Then, the three locking projections 15f to 15h are separated from the outer box 2, and the left and right engagement projections 15d and 15e are pulled out from the respective engagement holes 9c. Next, when the heat exchange guard 15 is pulled upward, the lower engagement protrusions 15a to 15c are pulled out from the engagement holes 9c, and the heat exchange guard 15 can be removed. As described above, since the heat exchange guard 15 is easily attached and detached, the assembling is simplified, and the maintenance work can be easily performed.
