Benefits of technology

[0017]An object of the present invention is to provide visual feedback of the rate and volume of air flowing from the exhaust point by use of color, texture, and movement.
[0018]Household appliances or other machines vent in to a duct system to vent exhaust air into outside of a building. The point at which a duct vent breaches an exterior wall of the buildin...

Problems solved by technology

Dryers and other household appliances typically generate waste air which needs to be exhausted.
An occlusion prevents the flow of air from the vent tubing or duct work, thereby preventing the flow of appliance's exhaust air and increasing the risk of appliance failure, such as by overheating the appliance's motor, increasing drying times, or unsafe levels of heat buildup elsewhere.
A vent opening which is too occluded constitutes several risks.
It may effectively block the air flow from the appliance by completely obstructing the vent opening.
It may also increase the risk of fire by preventing the free flow of lint or other debris along with the exhaust air, thereby causing a clog in the vent tubing...

Embodiment Construction

[0026]FIG. 1 shows an exemplary embodiment of the present invention. The duct cover 101 has an open bottom 103, an inner wall 105, and a top wall 107. The duct cover 101 also has side walls 123. The open bottom 103, inner wall 105, top wall 107, and side walls 123 define an inner cavity 121. Disposed within this inner cavity 121 is a paddle wheel 113. The paddle wheel 113 rotates freely around an axle 115. The axle 115 is connected at each of its two ends at each of one of the two side walls 123, spanning the distance between them. The paddle wheel 113 has a plurality of paddles 109. In this embodiment, there are eight paddles 109.

[0027]Each of the paddles 109 may be substantially identical. Conversely, one or more of the paddles 109 may differ from the others in material aspects. For example, one of the paddles 109 may be weighted more than the others, thereby disposing the paddle wheel 113 toward a certain orientation.

[0028]The top wall 107 is curved to help direct air flow from t...

Abstract

A duct vent cover attaches to an exterior wall at a duct exhaust point. The duct vent cover comprises a hood, mounting bracket, and a paddle wheel. The duct vent cover shields the duct vent from weather effects. The paddle wheel deters the ingress of wildlife, such as, for example, birds, squirrels and other animals which nest in vents, while allowing the egress of exhaust air, lint, and other debris.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, but otherwise reserves all copyrights whatsoever.BACKGROUND[0002]I. Field[0003]This invention relates to covers for vents.[0004]II. Description of Related Art[0005]Dryers and other household appliances typically generate waste air which needs to be exhausted. This waste air is typically exhausted through tubing leading from the appliance to an outdoor space. Successful venting to the outdoors requires an aperture at the termination of the tubing through which the waste air can flow. This aperture is the vent opening.[0006]An effective vent opening allows the flow of air from the vent tubing and thus the appliance. Thus, it is advantageous to facilitate exhaust through the vent opening. An occlusion prevents ...
