<P>PROBLEM TO BE SOLVED: To solve such a problem that, when washing a filter of a cooking range hood, the oil dirt deposited in small openings arranged in a matrix in a filter is difficult to scrape out to remove from all of the openings even when scrubbing with a scrub brush. <P>SOLUTION: The filter 1 is constituted of a flat plate 2 in which slit openings 3 are arranged in parallel with each other. A combination filer 4 is configured to superpose two filters 1 one on top of another so that openings 3 are perpendicular to each other. The combination filer 4 is unfolded when washing the combination filer, thus the oil dirt deposited in the openings 3 is easily removed by moving the scrub brush in a longitudinal direction of the opening 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
