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...

Embodiment Construction

[0024]Referring now to FIG. 1, a first environmental view is generally shown at 10 in perspective of a ventilation system according to the present inventions in operative arrangement with respect to an item of conventional cooking equipment 12. As will be further described in additional detail, the present inventions include both an overall system, as well as a supply plenum module 14 secured to an overhead hood 16 incorporated into the improved filter and ventilation system, and which is associated with the cooking appliance 12 to maintain a desired pressure balance, or equilibrium, within an enclosed space in which the appliance 12 is situated during filtration of tie same. In particular, the module 14 operates in cooperation with the associated ventilation system in order to introduce, from an exterior location, a volume of raw untreated air for subsequent conditioning and conveyance to an inner hood perimeter, the same balancing the outflow of exhaust / filtered air withdrawn from...
