FILTER ATTACHING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To make a filter easily detachable and attachable when the filter is cleaned or exchanged. SOLUTION: A frame-like main body 21 is put in the opening of a front panel 15. A pair of upper and lower bulged sections 27 and 27 is formed on the upper and lower right sides of the main body 21 and groove holes 27a and 27a are made through the sections 27 and 27. A louver 23 is rotatably supported by the main body 21 in a horizontally opened state by engaging upwardly and downwardly protruded pins 29 and 29 with the holes 27a and 27a. On the backside of the louver 23, a pair of parallel guides 31 and 31 which are separated from each other in the vertical direction is formed. In addition, a filter 16 is removably inserted between the guides 31 and 31 and held in contact with the rear surface of the louver 23.
