Abstract
A dish washing and drying machine according to the present invention determines the sequence of washing conforming the amount of dirt and the quality of dirt on the dishes and executes the same. This dish washing and drying machine finds the amount of dirt from a value MF stored in a buffer MF 47 storing transmittance detected by a transmittance detecting circuit 41. In this case, an output is corrected by a value ME stored in a buffer ME 46 and a reference voltage, to correct the amount of degradation of a light receiving element. In addition, the quality of dirt is found from a value MD stored in a buffer MD 45 and a value MC stored in a buffer MC 44. The sequence of processing is determined from the amount of dirt and the quality of dirt. Accordingly, washing can be done depending on not only the amount of dirt but also the quality of dirt, for example, whether dirt is caused by oil, proteins or the like. As a result, it is possible to sufficiently and completely wash the dishes.
