a cover element rotatably connected to said filter housing to overlay an external surface of said filter housing, said cover element configured to cover said exhaust aperture element when exhaust air within said interior chamber comprises a first amount of pressure, and uncover said exhaust aperture element when said exhaust air within said interior chamber comprises a second amount of pressure which urges said cover element away from said exhaust aperture element; and
a weight element removably fixed to said cover element by magnetic coupling or an adherent, wherein said weight element urges said cover element toward covering said exhaust aperture element.
2. The lint catching system of claim 1 , wherein said second amount of pressure is provided by an obstructed condition of the filtration material supported in said filter housing.
3. The lint catching system of claim 1 , wherein said filter housing outlet disposes in a front panel wall which comprises said internal wall.
4. The lint catching system of claim 1 , wherein said weight element facilitates:
(i) engagement of said cover element with said filter housing when said exhaust air within said interior chamber comprises said first amount of pressure; and
(ii) disengagement of said cover element from said filter housing when said exhaust air within said interior chamber comprises said second amount of pressure.
5. The lint catching system of claim 1 , wherein said second amount of pressure is sufficient to overcome the amount of weight provided by said weight element and urge said cover element toward an open condition.
6. The lint catching system of claim 1 , wherein said weight element comprises a plurality of weight elements operable to provide an adjustable amount of weight, the plurality of weight elements including a first weight element fastened to the cover element in fixed engagement, and a second weight element magnetically and removably coupled to the first weight element.
7. The lint catching system of claim 1 , wherein the weight element is a second magnet removably fixed to the cover element by magnetic coupling to a first magnet, wherein said first magnet is fastened to said cover element, and said second magnet urges said cover element toward covering said exhaust aperture element with an adjustable amount of weight.
8. The lint catching system of claim 7 , wherein said first magnet and said second magnet facilitate:
(i) engagement of said cover element with said filter housing when said exhaust air within said interior chamber comprises said first amount of pressure; and
(ii) disengagement of said cover element from said filter housing when said exhaust air within said interior chamber comprises said second amount of pressure.
9. The lint catching system of claim 7 , wherein said second amount of pressure is sufficient to overcome a magnetic force of said first magnet and said second magnet, and urge said cover element toward an open condition.
10. The lint catching system of claim 7 , further comprising a plurality of magnets removably coupled to said second magnet to provide an adjustable amount of magnetic force.
11. The lint catching system of claim 1 , further comprising a plurality of weight elements including said weight element as a second weight element, wherein said plurality of weight elements includes a first weight element, fastened to an internal surface of said cover element by an adherent or a mechanical fastener, and said second weight element is magnetically coupled to said cover element through said first weight element on said internal surface.
12. A lint catching system, comprising:
a filter housing having an interior chamber defined by an internal wall;
a filter housing inlet disposed in said filter housing;
a filter housing outlet disposed in said filter housing;
an exhaust aperture element disposed in said filter housing to communicate with said interior chamber;
a cover element rotatably connected to said filter housing to overlay an external surface of said filter housing, said cover element configured to operate between a closed condition and an open condition; and
a weight element removably fixed to said cover element by magnetic coupling or an adherent, wherein said weight element urges cover element toward said closed condition;
wherein in said closed condition, said cover element impedes flow of exhaust air from said interior chamber through said exhaust aperture element; and
wherein in said open condition generated by an obstructed condition of a filtration material supported in said filter housing, said cover element allows said exhaust air to flow from said interior chamber through said exhaust aperture element.
13. The lint catching system of claim 12 , wherein an obstructed condition of the filtration material supported in said filter housing causes an increase in pressure in the filter housing that urges the cover element toward the open condition.
14. The lint catching system of claim 12 , wherein said filter housing outlet disposes in a front panel wall which comprises said internal wall.
15. The lint catching system of claim 12 , wherein said weight element facilitates:
(i) disposition of said cover element in said closed condition when exhaust air within said interior chamber comprises a first amount of pressure; and
(ii) disposition of said cover element in said open condition when said exhaust air within said interior chamber comprises a second amount of pressure.
16. The lint catching system of claim 15 , wherein said second amount of pressure is sufficient to overcome the amount of weight provided by said weight element and urge said cover element toward said open condition.
17. The lint catching system of claim 12 , wherein said weight element comprises a plurality of weight elements operable to provide an adjustable amount of weight, the plurality of weight elements including a first weight element fastened to the cover element, and a second weight element magnetically and removably coupled to the first weight element.
18. The lint catching system of claim 12 , further comprising a magnet removably coupled to said weight element on said cover element, said magnet configured to urge said cover element toward said closed condition.
19. The lint catching system of claim 18 , wherein said magnet facilitates:
(i) disposition of said cover element in said closed condition when exhaust air within said interior chamber comprises a first amount of pressure; and
(ii) disposition of said cover element in said open condition when said exhaust air within said interior chamber comprises a second amount of pressure.
20. The lint catching system of claim 19 , wherein said second amount of pressure is sufficient to overcome a magnetic force of said magnet and urge said cover element toward said open condition.
21. The lint catching system of claim 18 , wherein said magnet comprises a plurality of magnetic strips removably coupled to said weight element on said cover element to provide an adjustable amount of weight on the cover element.
22. A lint catching system, comprising:
a filter housing having an interior chamber defined by an internal wall;
a filter housing inlet disposed in said filter housing;
a filter housing outlet disposed in said filter housing;
a filtration material operably coupled to said filter housing outlet;
an exhaust aperture element disposed in said filter housing to communicate with said interior chamber;
a cover element rotatably connected to said filter housing to overlay an external surface of said filter housing, said cover element configured to cover said exhaust aperture element when exhaust air within said interior chamber comprises a first amount of pressure, and uncover said exhaust aperture element when said exhaust air within said interior chamber comprises a second amount of pressure which urges said cover element away from said exhaust aperture element; and
a weight element removably fixed to said cover element by magnetic coupling or an adherent, wherein said weight element urges said cover element toward covering said exhaust aperture element.
