<p>PROBLEM TO BE SOLVED: To enable an air filter to cover the whole rear surface of a suction grill for sufficiently filtering dusts floating in the air by providing a filter guide member having first and second connecting pieces connected to upper and lower ends of first and second guide rails. SOLUTION: When a suction grill is turned open forward, first and second grill brackets 80 and 81 tightly fixed to the both ends of rear side thereof move bent magnets 120 while being also turned with the suction grill. Magnets 12C turn a filter guide member 100 therewith. which is hinged on the lower end of the suction grill by way of a hinge shaft 90, to the predetermined tilt angle of the suction grill by magnetic attraction. As a result, an air filter can be attached onto the front surface of the suction grill with good degree of adhesion to cover the same, thereby enhancing the removal efficiency of dirt and enabling filtered dirt to be easily removed.</p> |
