Device of evaluating the dirt condition of an oven cavity

摘要

A cracking cell (1), typically catalytic is located in the ventilation channel of an oven and associated with the measurement of temperature (2), measurement of energy released by cracking the stain molecules (3), control of heat supplied to cell (4) and data processing (5). The energy released may be measured by temperature difference or by the cell heating requirement and is used to evaluate staining at a particular time and over a period.
