Abstract

PURPOSE: To surely grasp a rinsing completion by housing a sensor composed of a light emitting diode and a phototransistor in a washing tank, discriminating the turbidity of a rinsing water and operating an alarm from the result.
CONSTITUTION: The sensor fitted inside the washing tank is composed in containing a mesh-like protecting cylinder 4, an LED 5 and a phototransistor 6. To the LED 5, a constant voltage is supplied by an LED driving circuit 7, and a fixed LED light-emitting quantity 10 is emitted. The LED light-emitting quantity 10 is weakened by a turbid quantity of the rinsing water, a light- receiving quantity 11 smaller than the LED light-emitting quantity 10 is light- received to the phototransistor 6, and the signal is transmitted to a sensor circuit 8. The sensor circuit 8 discriminates the turbidity of the water by the signal from the phototransistor 6, and when the degree is made into a fixed transparency or above, it is sent to an alarm circuit 9, the rinsing completion is transmitted, and simultaneously, an operation is stopped.
