<p>PURPOSE: To prevent the fall-out of longitudinal and lateral filters to enhance the reliability of assembling in a dust collecting filter of an air purifier assembled in a grid from the longitudinal and lateral filters. CONSTITUTION: In each of plural longitudinal filters and plural lateral filters 25, 26, parallel grooves 27 are formed at regular intervals from one edge thereof, and stopper projecting parts 28 are installed projectingly from one side edge of the parallel grooves 27 toward the other side edge at an inlet position thereof and also notched parts 29 are provided at the other edge on an extension of the parallel grooves 27. The other side edge at an inlet position of the parallel grooves 27 is obliquely cut out to form guide recessed parts therein. On the assembling, the longitudinal and the lateral filters 25, 26 are aligned with each other at one side edges to engage the parallel grooves 27 thereof with each other from the guide recessed parts around the stopper projecting parts 28, and the opposite stopper projecting parts are inserted into the notches 29 to prevent the fall-out of the longitudinal and the lateral filters 25, 26 by the stopper projecting pans 28 to assemble a dust filter 20 in a grid.</p> |
