US 5,706,796 A · Heat diffusion ovens

Abstract

An oven structure that includes a housing with an internal refractory surface and two heat diffusion walls with apertures at spaced apart and parallel relationship with respect to each other defining a centrally disposed baking chamber and two combustion chambers. The apertures allow a predetermined amount of heat to pass through to the baking chamber without affecting the object being baked by direct contact with flames or other areas with excessive heat concentration. A uniform temperature is maintained within the baking chamber with the hot gases passing through the apertures to the baking chamber where high pressure is developed but the top with the hottest gases and push the mass of gases with a lower temperature down and into the exhaust system.

Dependent claims

An oven structure, comprising:

A) housing means having a centrally disposed baking chamber, first and second adjacent combustion chambers sandwiching said baking chamber;
B) first and second heat diffusion walls separating said combustion chambers from said baking chamber, said first and second heat diffusion walls include each a plurality of openings wherein said first and second heat diffusion walls include a plurality of cooperating stackable members defining said openings in between adjacent members;
C) means for heating up the space within said combustion chambers;
and
D) exhaust means that permits the heated gases inside said baking chamber to exit so that a substantially uniform temperature is maintained within said baking chamber.
