Abstract
An improved self-cleaning oven (,) is provided having an assembly (,) to control the cleaning cycle time of the oven (,) depending upon the degree of oven contamination and soil present therein. The assembly (,) includes a measuring chamber (,) as well as a passageway (,) communicating the interior (,) of the oven (,) and the chamber (,). A smoke detector (,) (preferably an infrared smoke detector) is associated with the chamber (,) and is coupled with a controller (,) so as to measure a parameter of smoke passing through the chamber during at least a portion of the cleaning cycle. This parameter is then used to determine the proper duration of the cleaning cycle. In preferred forms, measuring chamber (,) is equipped with an ambient air inlet (,) and outlet (,) so as to draw an ambient air stream through the chamber (,) between the smoke detector (,) and the oven gas stream.
