Abstract
A shield for use with a conveyor oven for redirecting a thermal exhaust flow. The conveyor oven has a first exterior surface defining an inlet aperture and a second exterior surface defining an outlet aperture. A first shield secures against the first exterior surface of the oven and at a location proximate and above the inlet aperture. A second shield secures against the second exterior surface of the oven and at a location proximate and above the outlet aperture. Each of the first and second shields further includes a body with a forwardly projecting and elongated front surface, first and second side surfaces, and a top surface angling in a generally upward direction between the side surfaces and from the front surface toward the associated exterior oven surface. The body further defines an interiorly hollowed and downwardly facing interior proximate the associated oven aperture. An elongated aperture is defined within the angled top surface, between the first and second side surfaces, and proximate the associated exterior surface of the oven. The shield redirects a thermal exhaust flow emanating through the aperture of the conveyor oven and in an upward direction towards a venti…
