SELF-CLEANING METHOD FOR A COOKING APPLIANCE |
摘要 |
A self-cleaning system for a convection cooking appliance controls the activation and deactivation of multiple heating units, as well as a blower, throughout an initial preheat and subsequent phases of a cleaning operation. In accordance with the preferred self-cleaning method, an initial, catalyst pre-heat stage is followed by a moderately high- temperature presoak stage. For the main cleaning operation, a high temperature stage is initiated in combination with a high convection air flow to establish high oven surface temperatures in a minimal time frame. This timed stage is followed by a cool down period wherein both the temperature and convection speed is reduced. Thereafter, an intermediate temperature heating stage with medium convective air flow followed by a cooling stage are provided for preset time periods. This combination of intermediate temperature heating and subsequent cooling stages is repeated until the total self-cleaning time is completed.
