Damper air filter

Abstract

The present invention enables means to provide filtered warm and cooled air into a room by passing the warm and cooled air through an air filter so that the air filter removes contaminants from the air stream. The contaminants are typically introduced into the air from contaminants lodged within the connecting ductwork. A filter is fitted to the damper downstream of the warm and cooled air entering a room so that contaminants from the duct do not contaminate the room's air.

[0005] DAMPER AIR FILTER

[0006] FILED WITH

[0007] THE UNITED STATES PATENT AND TRADEMARK OFFICE

[0008] BACKGROUND OF THE INVENTION

[0009] Field of the Invention

[0010] The embodiments of the present invention relates to air filtration, and more particularly, to the incorporation of an air filter into an air damper that permits air to flow from the air source into a room for heating and cooling.

[0011] Description of the Prior Art

[0012] Present air dampers for room heating and / or cooling permit unfiltered air from an air source to enter a room with airborne contaminants which often time may be harmful to a room’s occupants.

[0013] Some sources of heated and cooled air have a filter to filter the warm and cooled air at its source but the air must be communicated to a damper by means of ducts, and contaminants in the ducts are released into the heated and cooled air.

[0014] SUMMARY OF THE INVENTION

[0015] Accordingly, an object of the embodiment of the present invention is to provide means to provide filtered warm and cooled air into a room by passing the warm and cooled air through a filter, so that the filter removes contaminants from the air stream, said contaminants having been introduced into the air from contaminants lodged within the connecting transmission ducts. A filter is fitted to the damper downstream of the warm and cooled air entering a room so that contaminants from the duct do not contaminate the rooms air

[0048] The embodiments of the present invention will implement the introduction of filtered warm and cool air into a room by means of equipping a damper with a replaceable air filter.

[0049] As shown in cut-away perspective view FIGURE 1 of invention 10 unfiltered air 16a enters from the rear and passes through replaceable filter 20a wherein contaminants and particles are filtered-out which result in uncontaminated air filtered air. Non-porous enclosure encases the damper on all sides other than the rear which receives unfiltered air 16a and the front of the damper wherein filtered air 16b is released into a room. Replaceable air filter is typically rectangular in shape with the thickness determined by the size of the air damper.

[0050] Cut-away rear perspective view of FIGURE 2 depicts disposable filter 20 displaced from the rear of the damper and when assembled to filter stop 20b, filter 20 is held in place by filter retainer latch 20d.

[0051] FIGURE 3 is a rear perspective view of damper apparatus 10 illustrating unfiltered air 16a transmitted to the rear of invention 10 where replaceable filter 20 (not shown) is located and after unfiltered air

[0052] 16a flows through replaceable filter 20, clean air 16b enters into the room.

[0053] FIGURE 4A is a side elevational view illustrating damper 14 assembled to wall and / or ceiling 12. Air duct connector 24 attaches to air register box 26 which in turn directs unfiltered air 16a into replaceable air filter 20 (not shown).

[0054] FIGURE 4B illustrates wall and / or ceiling 12 with damper 28 removed from wall and / or ceiling 12 for replacement of replacement air filter 20 (not shown).

[0055] FIGURE 5 is a rear cut-away perspective view of the damper apparatus showing the damper fitted with replaceable filter 20 (not shown) that assembles from the side 30 and with air flow controlling mechanism 40. Filter guard 32 rotates and provides means to maintain replaceable air filter 20(not shown) in place in middle air filter holder frame 34 and rear air filter holder frame 36. The combination of middle air filter holder frame 34 and rear air filter holder frame 36 form a channel wherein filter 20 (not shown) is restrained and held in place. FIGURE 6 is a rear cut-away perspective view of the damper apparatus showing the damper fitted with replaceable filter 20 (not shown) that assembles from the side 30 and without air flow controlling mechanism. Filter guard 32 rotates and provides means to maintain replaceable air filter 20 in place in middle air filter holder 34 and rear air filter holder 36.
