Overhead ventilation system incorporating a downwardly configured rear supply plenum with upward configured and reverse bended directional outlet

Abstract

A ventilation system for use with a cooking appliance to maintain an atmospheric pressure balance existing within an enclosed space surrounding the cooking appliance. A hood establishes a three-dimensional and interiorly recessed configuration and which is supported above the appliance. A filter within the hood communicates with a vacuum driven exhaust extending from the enclosed space. A supply plenum secures in downwardly and opposing fashion relative to a side of the cooking appliance. An air intake communicates the supply plenum with an exterior environment, the plenum terminating in an upwardly angled outlet for introducing intake air along the side of the appliance, resulting in heating and elevating the intake air within a perimeter defined by the hood and thereby minimizing loss of conditioned air existing within the enclosed space.

Description

BACKGROUND OF TEE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to an overhead ventilation system, such as is utilized in combination with commercial cooking appliances or industrial oven processes. More particularly, the present invention teaches a ventilation system, such as in use with a commercial pizza or other food related cooking process and by which products of such process include heated air, grease and / or other contaminants. The present invention is an improvement over prior art oven hood designs, and by which an associated inlet plenum is reconfigured to assist in introducing air from an exterior, while reducing the requirement for oversized air conditioning or heated makeup air units,[0003]2. Description of the Prior Art[0004]The prior art is well documented with examples of oven hood and makeup air devices, such as which are utilized in the removal of heat and airborne particulates (i.e., grease, other solids, etc.) associated wit...

AI Technical Summary

Benefits of technology

[0015]The extended length of the intake supply plenum, combined with the arraying of the outlet relative to the side of the cooking appliance and the recessed interior of the hood, serves to better warm and precondition the raw intake air for rising within the hood interior. The configuration and arrangement of the plenum results in a volume of intake air introduced generally equaling that exhausted from the hood and, by virtue of establishing a pressure equilibrium within the hood interior, preventing loss of additional volumes of quality AC or heat conditioned air from within the enclosed space.

[0016]It is further noted that the length and depth of the supply plenum assists in maintaining an air velocity (i.e.,...

Problems solved by technology

A common problem in the prior art is the tendency of such devices to introduce significant volumes of untreated air, requiring further significant capacity from such as air conditioning ...
