초록 ▼

A core construction for use in a filter element includes a tubular member having a wall with opposite first and second ends. The first end is adaptable for engagement with structure, such as a frame utilized with a filter element. The second end is also engageable with external structure, such as a handle. Preferably, a filter element is constructed by rolling a media construction around the core construction. The media construction includes a corrugated sheet secured to a flat sheet rolled around the core construction into a coiled construction. The coiled construction has inlet flutes and outlet flutes. Methods for using and assembling filter elements preferably use core constructions as described herein.

A filter element comprising:(a) a core construction comprising a tube having a wall with opposite first and second ends; (i) said core construction first end including a hook construction; (A) said hook construction including at least a first hook; (ii) said core construction second end defining at least one void in said wall; and (b) a media construction comprising a corrugated sheet secured to a flat sheet rolled around said core construction into a coiled construction; the coiled construction having a plurality of flutes, a first end, and an opposite second end; (i) said plurality of flutes comprising inlet flutes and outlet flutes; (A) said inlet flutes being open at portions adjacent to said first end and closed at portions adjacent to said second end; and said outlet flutes being closed at portions adjacent to said first end and open at portions adjacent to said second end. 2. A filter element according to claim 1 wherein:(a) said hook construction includes first and second flanges; first and second cut out extensions; and a projecting rib; (i) said first and second cut out extensions being adjacent to said first and second flanges to permit said first and second flanges to deflect radially toward each other; (ii) each of said first and second flanges including a hook at a free end thereof; (iii) said projecting rib extending radially from said wall; said rib being oriented between said first and second flanges and said second end of said wall; and (b) said core construction second end defining a pair of voids in said wall; (i) said pair of voids being aligned with said first and second flanges. 3. A filter element according to claim 2 further including:(a) a frame having a central hub; said frame being secured to said coiled construction; (i) said core construction being secured to said frame; and (ii) said hooks on said first and second flanges engaging said central hub. 4. A filter element according to claim 3 further including:(a) a seal member oriented adjacent to said second end of said coiled construction and being supported by said frame. 5. A filter element according to claim 4 wherein:(a) said frame has a skirt and an axial extension; (i) said skirt circumscribing and securing said frame to said coiled construction; (ii) said axial extension having an annular portion; (A) said annular portion of said axial extension supporting said seal member. 6. A filter element according to claim 2 further including:(a) a knob secured to said coiled construction for manipulation of the filter element. 7. A filter element according to claim 6 wherein:(a) said knob has a grasping portion and a shaft; (i) said shaft including a pair of deflectable extensions each having a barb; (ii) said knob being snap-fit to said second end of said core construction by engagement between each of the barbs and said pair of voids in said wall. 8. A filter element according to claim 1 wherein:(a) said core construction tube comprises a cylinder. 9. A filter element comprising:(a) a core construction comprising a tube having a wall with opposite first and second ends; (i) said first end including a hook construction and a projecting rib extending radially from said wall; and (ii) said second end including at least one structure-receiving void; (b) a media construction comprising a corrugated sheet secured to a flat sheet rolled around said core construction into a coiled construction; the coiled construction having a plurality of flutes, a first end, and an opposite second end; (i) said plurality of flutes comprising inlet flutes and outlet flutes; (A) said inlet flutes being open at portions adjacent to said first end and closed at portions adjacent to said second end; and said outlet flutes being closed at portions adjacent to said first end and open at portions adjacent to said second end; (c) a frame and a seal member; said frame securing said seal member to said coiled construction; said frame having a skirt, an axial extension, and a central hub; (i) said skirt circumscribing and securing said frame to said coiled construction; (ii) said axial extension projecting axially from said second end of said coiled construction; said axial extension having an annular portion; (A) said annular portion of said axial extension supporting said first member to orient said first member in a radial direction; and (iii) said hook construction engaging said central hub to secure said frame to said core construction; (A) said central hub being trapped between said hook construction and said projecting rib; (d) a handle secured to said core construction by snap engagement between said handle and said at least one void. 10. A filter element according to claim 9 wherein:(a) said hook construction includes first and second flanges and first and second cut out extensions; (i) each of said first and second flanges including a hook at a free end thereof; and (ii) said first and second cut out extensions being adjacent to said first and second flanges to permit said first and second flanges to deflect radially toward each other. 11. A filter element according to claim 9 wherein:(a) said tube comprises a cylinder. 12. An air cleaner comprising:(a) a housing defining an interior; and (b) a filter element operatively and removably mounted within the filter interior; the filter element including: (i) a core construction comprising a tube having a wall with opposite first and second ends; said core construction first end including a hook construction; said hook construction including at least a first hook; said core construction second end defining at least one void in said wall; and (ii) a media construction comprising a corrugated sheet secured to a flat sheet rolled around said core construction into a coiled construction; the coiled construction having a plurality of flutes, a first end, and an opposite second end; said plurality of flutes comprising inlet flutes and outlet flutes; (A) said inlet flutes being open at portions adjacent to said first end and closed at portions adjacent to said second end; and said outlet flutes being closed at portions adjacent to said first end and open at portions adjacent to said second end. 13. An air cleaner according to claim 12 wherein:(a) said filter element includes a seal member oriented adjacent to said second end of said coiled construction; said seal member forming a seal with said housing. 14. A method of assembling a filter element; the method comprising:(a) providing a filter core having a first end and an opposite second end; (b) providing a media construction comprising a corrugated sheet secured to a flat sheet; (c) rolling the media construction around the filter core to form a coiled construction; the coiled construction having a plurality of flutes, a first end, an opposite second end, and an outer annular surface; (i) the plurality of flutes comprising inlet flutes and outlet flutes; (A) the inlet flutes being open at portions adjacent to the first end and closed at portions adjacent to the second end; and the outlet flutes being closed at portions adjacent to the first end and open at portions adjacent to the second end; and (d) securing at least one of: (i) the coiled construction to a frame by snapping the first end of the filter core to a frame; and (ii) a handle to the coiled construction by snapping a handle to the second end of the filter core. 15. A method according to claim 14 wherein:(a) securing includes securing both the coiled construction to a frame by snapping the first end of the filter core to a frame; and securing a handle to the coiled construction by snapping a handle to the second end of the filter core. 16. A method according to claim 15 wherein:(a) securing a handle is completed before securing the coiled construction. 17. A method according to claim 16 further including:(a) securing a seal member to the coiled construction. 18. A method according to claim 17 wherein:(a) securing a seal member to the coiled construction includes securing the coiled construction to a frame supporting the seal member. 19.
