Pressurized oven assembly

Abstract

A pressurized oven is provided having a fully sealed cavity, reduces heat lost, shortens cooking time and saves energy of oven operation. The pressurized oven includes a cavity component, a door assembly, heating elements and a control system that includes a relief valve on top of the cavity. The relief valve includes a valve weight and a venting stub, wherein the valve weight sits on the top of the venting stub. The valve weight disposed on top of the venting stub remains closed and the gas is not released when the pressure is not sufficient to lift the valve weight. When the pressure inside the oven is sufficient to lift the valve weight, the valve weight block is lifted to open the valve, the gas is released and the pressure is decreased. Once the pressure becomes less than the valve weight, the valve closes and gas is no longer released.
