SELF-CLEANING SYSTEM FOR CONVECTION COOKING APPLIANCE

摘要

A self cleaning sequence for a convection cooking appliance employs high velocity air to heat an oven cavity and components/ducting of an air circulation passage to self cleaning (pyrolitic) temperatures. In accordance with the invention, the self-cleaning sequence includes four stages: a vent catalyst pre-heating stage; a low molecular weight hydrocarbon burn-off stage; a high temperature cleaning stage; and a cool down stage.
