Patent number: 8062396Abstract: The purpose of this invention is to provide a pleated-type filter used for an apparatus for collecting dust that is optimally designed and to provide the apparatus for collecting dust using the filter, wherein the pleated-type filter can keep the resistance to its ventilation low when the filter is installed in the apparatus for collecting dust so that the pleats are directed vertically, and wherein the area for installing the main bodies of the pleated-type filters can be reduced as much as possible. The ratio of the apertures of the pleats (P/H) that is defined by the intervals (P) between the crests of adjacent pleats of the main body and the heights (H) of its pleats ranges from 0.1 to 0.3. The ratio is determined based on the relationship between the area for installing the pleated-type filters and the ratio of the apertures of the pleats (P/H).Type: GrantFiled: June 28, 2007Date of Patent: November 22, 2011Assignee: Sintokogio, Ltd.Inventors: Hiroyuki Amano, Hiroaki Watanabe, Hidenori Ikeno, Tomoyuki Suzuki
