System for cleaning circulating oven air with reduced thermal disruption

Abstract

An air cleaning system for an oven that includes a cooking chamber configured to receive a food product includes a catalytic converter, an input array and a preheater. The catalytic converter may be configured to clean air expelled from the cooking chamber. The input array may include perforations through which cleaned air that has been processed by the catalytic converter is provided into the cooking chamber. The preheater may be disposed proximate to the cooking chamber to use heat generated by the cooking chamber to preheat the cleaned air prior to entry of the cleaned air into the cookingchamber through the input array.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Application No. 62 / 428,141, filed November 30, 2016, and U.S. Application No. 15 / 810,974, filed November 13, 2017, the entire contents of which are incorporated by reference in their entirety. into this article. technical field [0003] Example embodiments relate generally to ovens and, more particularly, to ovens capable of facilitating cleaning of air circulated through a cooking chamber of the oven to reduce the impact of thermal conditions in the oven. Background technique [0004] Cooking inherently produces smoke and particulates that can foul the interior of the oven and / or contaminate the exhaust gases leaving the oven. To address these issues, some ovens have used catalytic converters or other such cleaning techniques. [0005] Catalytic converters generally use catalysts to facilitate chemical reactions to convert toxic gases or pollutants in exhaust gases to less ha...
