Title: APPARATUS AND SYSTEM FOR SOLID STATE OVEN ELECTRONICS COOLING
Abstract:
An air circulation system for an oven includes an inlet cavity, an attic region and a cooling fan. The oven includes a cooking chamber configured to receive a food product and an RF heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The air circulation system is configured to provide air for cooling the solid state electronic components. The inlet cavity is disposed below the cooking chamber. The attic region is disposed above the cooking chamber and housing the solid state electronic components. The cooling fan isolates the inlet cavity from the attic region to maintain the inlet cavity at a pressure below ambient pressure to draw cooling air into the inlet cavity via an inlet array, and to maintain the attic region at a pressure above ambient pressure to discharge air that has cooled the solid state electronic components from an oven body of the oven.
