Vent cap assembly

Abstract

A vent assembly that includes an intake member having an open end, an exhaust member, and a deflector. The exhaust member has an open end and extends coaxially with the intake member. The deflector is positioned along an interior surface of the intake member. The deflector defines a surface that slopes towards the open end of the intake member. The deflector is configured to direct liquid in the intake member towards the open end of the intake duct.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to components of a vent system for a heating appliance, and more particularly relates to a vent system having an exhaust vent opening and intake vent opening. [0003] 2. Related Art [0004] Exterior intake and / or exhaust venting systems are generally known for use in buildings and other such structures. Such vents can be used for a variety of venting purposes, for example, to vent fireplaces, furnaces, water heaters, boilers, dryers, exhaust fans, and a many other such appliances and devices. Some such vents are primarily exhaust vents while others are primarily intake vents, and still others include structure that allows them to function as both intake and exhaust vents. [0005] In one example, chimneyless gas fireplaces often include intake / exhaust venting units that are mounted on the outside of an exterior wall that provide a through-the-wall connection to a double walled col...

AI Technical Summary

Benefits of technology

[0008] The present invention relates to vent assemblies that includes intake and exhaust apertures and a vent cap or vent cover. The example vent assemblies are configured to reduce the flow of unwanted liquids into the intake and exhaust apertures. The example vent assemblies can also provide improved fluid flow into and out of the respective intake and exhaust apertures, minimize the reverse flow of fluids exhausted from the exhaust aperture into the intake aperture, improve the flow of intake air into the intake aperture, and prevent weather conditions from generating adverse effects on the vent assembly performance.

[0011] A further aspect of the invention relates to a vent assembly for use with a vent, the vent including an intake member defining an intake aperture and an exhaust member defining an exhaust aperture. The assembly includes a first deflector, a divider, and a first fluid shield. The first deflector is positioned at least partially within the intake member along an interior surface of the intake member. The first deflector is sloped relative to the interior surface in a direction toward the intake aperture. The divider is positioned between the exhaust aperture and the intake aperture and is configured to minimize fluid flow between the exhaust aperture and the intake aperture. The first fluid shield extends at least partially between the intake aperture and the divider and is arranged vertically above the intake and exhaust members.

Problems solved by technology

However, many of the existing vent caps are not aesthetically pleasing, may get hot due to high temperature exhaust gases, and are exposed to weather conditions and therefore may be damaged.

One disadvantage of many venting units is that they do not adequately compensate for weather conditions.

Wind can create backdraft of exhaust gases into the heating appliance through the exhaust vent, which may result in extinguishing of a combustion flame in the heating appliance.

Rain and snow can enter the heating appliance and related ducting through the exhaust and intake vent portions of the venting unit, and potentially cause water damage.
