BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of exhaust hoods for dryers, and more particularly to an outside guard for the exhaust opening of the exhaust hood.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 5,547,422; 5,616,076; 5,722,181 and 5,916,023 the prior art is replete with myriad and diverse guards for exhaust hoods.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical dryer vent guard. Often, birds and other creatures make their way inside the dryer ventilation systems of homes and cause numerous problems. The only way inside the ventilation system is through the exhaust opening of the dryer exhaust hood exposed to the outside.
As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved dryer vent guard and the provision of such a construction is a stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention provides a dryer exhaust hood that prevents birds and other creatures from entering a dryer ventilating system. The guard includes an air-pervious panel sized to fit over the exhaust opening of the exhaust hood, a pair of spaced guard flanges that overlie the flanges on opposing sides of the exhaust hood, and a pair of resilient clips that frictionally engage and releasably secure the guard flanges to the hood flanges. The guard also includes alignment tabs that extend from the air-pervious panel to engage portions of the exhaust hood adjacent the exhaust opening.
