Claims
- 1. An air cleaner element comprising:
- a) a connector unit including a central core, an outer frame member surrounding the core, and a plurality of spoke arms extending radially outwardly from the core to the frame member to define a plurality of like configured spaces, and
- b) a plurality of filter paper units individually disposed in said spaces, each unit comprising a sheet of filter paper corrugated into a plurality of folds extending from one side to the other of the sheet to define a plurality of parallel ridges, and each unit being arranged such that each ridge of each of the folds thereof lies on or extends parallel to a radial line extending outwardly from the central core and bisecting an associated space, said ridges being disposed in a zigzag manner as viewed in a direction perpendicular to an axial direction of the air cleaner element and parallel to said radial line;
- c) wherein each spoke arm abuts and interconnects confronting side edges of adjacent filter paper units.
- 2. An air cleaner element according to claim 1, wherein there are at least two of the filter paper units.
- 3. An air cleaner element according to claim 1, wherein said connector is molded of a resin material.
- 4. An air cleaner element according to claim 3, wherein each of said folds has fold members pinched closely together at distal-end portions thereof over a prescribed length from a ridge of the fold, said fold members pinched closely together being encased in a region by said connector unit made of resin material, thereby defining openings between adjacent ones of the regions, which communicates with air passages defined between adjacent ones of said folds.
- 5. An air cleaner element according to claim 1, wherein each spoke arm has a groove-like air passage of U-shaped cross section which communicates with air passages defined between adjacent ones of said folds via regularly spaced openings in side walls of said spoke arm.
