<P>PROBLEM TO BE SOLVED: To provide an air purifier constituted so that air can be purified comfortably without causing a user to notice an air current and sound even when air is sucked at a high flow rate. <P>SOLUTION: This air purifier is constituted so that the bottom end part of a three-dimensional filter 3 is inserted/set in a filter receiver 2 having a cylindrical peripheral wall 6 and an air blowing-off part 8 at the bottom 5, a fan 4 is arranged under the bottom of the filter receiver 2, the surrounding air is sucked in the three-dimensional filter 3 from both of the ceiling surface side 3a and the side face side 3b of the three-dimensional filter 3 by driving the fan 4 and blown out through a blow-off port 8 of the bottom 5 of the filter receiver 2. The three-dimensional filter 3 consists of, for example, a columnar filter obtained by winding a flat material in a spiral state. It is desirable to make the flow resistance of the air entering from the side face side 3b larger than that of the air entering from the ceiling surface side 3a. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
