<P>PROBLEM TO BE SOLVED: To solve a problem in a conventional range hood that attached oil and dust are hardly removed even when a filter is rotated as the filter has the disc shape, which causes the increase of power consumption necessary for removal. <P>SOLUTION: This range hood applies a constitution for rotating a filter 7 provided with a cylindrical face 15, and a constitution provided with reverse rotation of an air distribution fan 6 and a blade 22 for a turbo fan as shown in Fig.3, thus the oil and dust attached to the filter 7 can be effectively removed in a short time by the action of centrifugal force and drag by air distribution, and the clogging of the filter 7 can be prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
