Filter cartridges; air cleaner assemblies; housings; features; components; and, methods
Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly cannot be fully closed, even if a cartridge is nested therein, and appears to be sealed, unless that cartridge is a proper one for the system of concern. The effect is to prevent an inappropriate cartridge, that does not properly seal, from being inadvertently installed in the assembly.
1. An air filter cartridge comprising:
(a) a media pack having an outer perimeter and opposite flow faces; and,
(b) a housing engagement member surrounding the media pack; the housing engagement member including a seal arrangement having: a pinch seal portion; and, a seal support portion; and,
(c) a member of an air cleaner security, housing closure, inhibition arrangement positioned in the housing engagement member;
(i) the member of an air cleaner security, housing closure, inhibition arrangement comprises a pocket arrangement including at least one receiving pocket therein;
(A) the at least one receiving pocket being a closed interior pocket;
(B) the pinch seal portion having an outer perimeter and opposite surfaces;
(C) the at least one receiving pocket being positioned radially inwardly from the outer perimeter of the pinch seal portion; and,
(D) the at least one receiving pocket of the pocket arrangement extending further toward one of the flow faces than adjacent portions of each of the opposite surfaces of the pinch seal portion.
2. An air filter cartridge according to claim 1 wherein:
(a) the at least one receiving pocket of the security, housing closure, inhibition arrangement comprises a downstream arrangement that is engaged by a portion on a housing toward a downstream side of the seal arrangement, in use.
3. An air filter cartridge according to claim 1 wherein:
(a) the receiving pocket arrangement comprises a single receiving pocket.
4. An air filter cartridge according to claim 1 wherein:
(a) each receiving pocket of the pocket arrangement extends at least 10 mm further toward one of the flow faces than adjacent portions of each of the opposite surfaces of the pinch seal portion.
5. An air filter cartridge according to claim 1 wherein:
(a) the housing engagement member is configured to define a receiving trough between at least a portion of the housing engagement member and a remainder of the filter cartridge; and,
(i) the at least one receiving pocket of the housing engagement member defines a deeper recess than portions of the receiving trough.
6. An air filter cartridge according to claim 1 wherein:
(a) the at least one receiving pocket has a peripheral length dimension, at an entrance thereto, that is at least 15 mm.
7. An air filter cartridge according to claim 1 wherein:
(a) the receiving pocket has an entrance located radially interiorly from the pinch seal portion.
8. An air filter cartridge according to claim 1 wherein:
(a) the receiving pocket has an entrance including an interior radial recess in the pinch seal portion.
9. An air filter cartridge according to claim 1 wherein:
(a) the housing engagement member includes an exterior peripheral surface with at least one exterior member of the receiving housing closure inhibition arrangement therein.
10. An air filter cartridge according to claim 9 wherein:
(a) the at least one exterior member of the security housing closure inhibition arrangement is a recess member positioned with at least a portion thereof in the seal support portion of the housing engagement member.
11. An air filter cartridge according to claim 1 wherein:
(a) the opposite flow faces are planar.
12. An air filter cartridge according to claim 11 wherein:
(a) the opposite flow faces are planar in planes perpendicular to a flow direction between the opposite flow faces.
13. An air filter cartridge according claim 1 wherein:
(a) the pinch seal portion has a portion slanted to a flow direction between the opposite flow faces.
14. An air filter cartridge according to claim 1 wherein:
(a) the housing engagement arrangement is molded-in-place over a side panel arrangement and a side cover arrangement without being in direct contact with media.
15. An air filter cartridge according to claim 1 wherein:
(a) the media pack comprises a facing media section secured to a fluted media section.
16. An air cleaner assembly comprising:
(a) an openable cleaner housing defining an interior; and,
(b) an air filter cartridge including media having opposite flow faces and a housing engagement member surrounding the media pack; the housing engagement member including a seal arrangement having: a pinch seal portion; and, a seal support portion; the air filter cartridge being removably installed in the air cleaner assembly;
(c) the air cleaner assembly including a security, housing closure, inhibition arrangement configured with a first member on the air cleaner housing and a second member on the air filter cartridge;
(i) the second member of the air cleaner security, housing closure, inhibition arrangement comprises a pocket arrangement including at least one receiving pocket therein;
(A) the at least one receiving pocket being a closed interior pocket;
(B) the pinch seal portion having an outer perimeter and opposite surfaces;
(C) the at least one receiving pocket being positioned radially inwardly from the outer perimeter of the pinch seal portion; and,
(D) the at least one receiving pocket of the pocket arrangement extending further toward one of the flow faces than adjacent portions of each of the opposite surfaces of the pinch seal portion;
(ii) the security, housing closure, inhibition arrangement being such that:
(A) if an alternate cartridge does not have the second member, but the cartridge is otherwise configured to at least appear from outward appearance to properly fit the housing, the first member will prevent the housing from closing with that alternate cartridge installed; and,
(B) the first member and the second member, of the security, housing closure, inhibition arrangement will interact to allow housing closure, when the cartridge is properly installed.
