Soffit Vent

Abstract

A soffit vent for dispersing moist air. The soffit vent can receive moisture through an interface unit which is connected to an elbow unit. The elbow unit is constructed to guide the moisture into an extension unit. The extension unit then leads the moisture to an outdoor area through an end unit. A flap unit is disposed between the extension unit and the end unit to prevent a backdraft of moisture. The end unit has a plurality of fixed baffles that are oriented upwardly to direct moisture upward and away from a building.

In one embodiment, the interface unit 16 is configured to receive warm, moist air from an exhaust fan. The open upper end of the cavity 15 is configured to receive the interface unit 16. In one embodiment, the elbow unit 11 has a lip 17 extending outwardly around the inlet portion 13. Under this embodiment, the lip 17 further comprises a plurality of apertures 18 configured to receive a fastener. Furthermore, the interface unit 16 comprises a plurality of corresponding apertures 19 configured to align with the plurality of apertures 18 of the elbow unit, such that a pair of aligned apertures can receive a fastener therethrough in order to secure the elbow unit 11 to the interface unit 16.

[0023] The elbow unit 11 is configured to receive a flap unit 22 between the elbow unit 11 and the interface unit 16. In one embodiment, the elbow unit 11 has a plurality of flap wells 21 in the lip 17 on the outlet portion 14 configured to receive a plurality of flap tabs 23 attached opposite each other on a top portion of the flap unit 22. The flap tabs 23 are configured to be movable within the flap wells 21 to allow the flap 22 to rotate around an axis defined thereby.

[0024] The flap unit 22 is configured to be movable in one direction, while preventing movement in an opposite direction. In one embodiment, there are a plurality of barriers 24 on the elbow unit 11 between the housing 12 and the flap unit 22 configured to prevent the flap unit 22 from being movable in a way that would allow backdraft into the elbow unit 11. In one embodiment, the barriers extend upward from a bottom surface of the elbow unit 11 opposite of an extension unit 25.

[0025] The extension unit 25 is attached to the elbow unit 11 at the outlet portion 14 wherein the flap portion 22 rests between the extension unit 25 and the elbow unit 11. The extension unit has a first end 26 and a second end 27 wherein the first end 26 is configured to slidably attach to the elbow unit 11. The second end 27 is configured to slidably receive an end unit 28 therein. The end unit 28 is configured to rest frictionally over the second end 27. The extension unit 25 is configured to receive moisture from the elbow unit 11 and further direct the moisture away from the interface unit 16.

[0026] In one embodiment, the extension unit 25 contains a plurality of prefabricated ridges 29 that separate the extension unit into a plurality of segments. Each prefabricated ridge 29 of the plurality of prefabricated ridges 29 is configured to enable the user to remove one or more segments of the extension unit thereof with a cutting device in order to fit into a desired location. In one embodiment, the prefabricated ridges are equally spaced from one another and define a predetermined distance. This allows a user to remove segments without the additional need for a measuring tool, such as a tape measure.

[0027] In another embodiment, the extension unit 25 is made of a flexibly movable material. This embodiment will enable a user to bend or adjust the path of the extension unit 25 as needed to properly orient the soffit vent to release the warm, moist air and condensation properly away from the building. Furthermore, under another embodiment, the prefabricated ridges 29 are configured to be foldable in order to assist the user in placing the extension unit 25 into a bent or flexed position

[0028] The end unit 28 is comprised of an end housing 30 defining an end unit chamber and an end cap 31 configured to release warm, moist air into an outdoor environment. The end cap 31 acts as a termination point for the warm, moist air and is shaped to fit into the end unit 28. In one embodiment, the end cap 31 is angled downward away from a top surface of the end unit. In a further embodiment, the end cap 31 is removable from the soffit vent 10 to enable a user to clean the end unit chamber in the event that outdoor particulate matter or excess condensation builds up therein.

[0029] Under one embodiment, the end unit 28 contains a plurality of slidable fastener interfaces 32 extending outwardly from opposite ends on a top surface thereof. The slideable fastener interfaces 32 are configured to slide onto a fastener attached to an underside of an eave of a roof. Under this embodiment, the end unit 28 sits flush with a gutter line and will always be partially protected from outdoor elements because of its location under the eave of the roof. In the illustrated embodiment, a pair of fastener interfaces 32 are disposed on opposing ends of the end unit 28. Each fastener interface 32 comprises a slot that extends beyond the lateral sides of the end unit 28.

[0030] Referring now to FIG. 2, there is shown an internal side view of an embodiment of the soffit vent. In one embodiment, the elbow unit 11 further comprises a drip tongue 20. The drip tongue 20 is located centrally on a bottom surface of the elbow unit wherein the drip tongue is comprised of an extension from the elbow unit 11 with a hole therein. The drip tongue 20 is configured to be an immediate egress point for condensation wherein condensation will build up in the extension and drip through the hole thereof. In cold climates, this embodiment is designed to prevent condensation build up that can eventually lead to damage caused by freezing. In a further embodiment, the elbow unit 11 is composed of a plurality of side walls. Each side wall of the plurality of side walls is pitched towards the drip tongue. This embodiment is configured to promote more efficient egress of condensation from the elbow unit. The evacuation of condensation by the drip tongue 20 is useful in cold environments as it prevents ice damming from forming on the soffit vent.

[0031] Referring now to FIG. 3, there is shown a side perspective view of an embodiment of the soffit vent. Under this embodiment, the end cap contains a plurality of parallel baffles 33 on a horizontal plane. The plurality of parallel baffles 33 are angled towards the upper surface of the end cap. This arrangement ensures that the warm, moist air is directed upwardly and outwardly relative to a building equipped with the soffit vent 10. Furthermore, the plurality of parallel baffles 33 is also configured to prevent backdraft and to prevent large animals from entering the soffit vent.

[0032] In one embodiment, there is a mesh screen disposed between the end unit and the extension unit 25. Under this embodiment, the mesh screen is configured to prevent insects and other small pieces of particulate matter from entering the soffit vent from an outdoor environment. Furthermore, the mesh screen is configured to have no negative impact upon a static pressure level inside of the soffit vent.

[0033] In one embodiment, the interface unit 16 further comprises an interface adapter 34. The interface adapter 34 is designed to receive an input duct wherein the input duct with transport warm, moist air into the soffit vent. In one embodiment, the interface adapter 34 is a tubular unit configured to receive a ventilation duct and to form an airtight seal therewith. In the illustrated embodiment, the interface adapter is comprised of a plurality of tiered tubular units wherein each tiered tubular unit is configured to receive a ventilation duct thereon to form an airtight seal therewith.

[0034] Referring now to FIG. 4, there is shown a perspective view of an embodiment of the soffit vent with a ventilation duct attached thereon. In one embodiment, moisture is pulled into the soffit vent because of a bathroom exhaust fan. Under this embodiment, the bathroom exhaust fan directs steam into a ventilation duct 35. Once the steam is directed into the ventilation duct 35, it is directed into the interface unit 16 and eventually into the elbow unit 11. From the elbow unit 11, the steam is directed into the extension unit 25, then outward through the end unit and the end cap 31 as directed by the plurality of parallel baffles 33.

[0035] It is therefore submitted that the instant invention has been shown and described in various embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
