Color Sensor For Washing Machines

Abstract:

A laundry washing machine includes a housing with conventional washing elements within the housing. A door on a door opening of the housing enables access inside the housing to the conventional washing elements. A sensor senses color of cloth prior to passing the cloth through the door opening. The sensor is positioned so that it senses the cloth in a dedicated area outside of the machine adjacent to the door or door opening.
