ABSTRACT:
The apparatus for measuring the degree of rinsing for use in a washing machine is provided with a source of light, a first phototransistor disposed to receive light emitted by the light source for producing a reference signal, a second phototransistor disposed to receive the light from the light source for producing a measuring signal corresponding to the amount of light received and a calculating circuit for arithmetically operating the reference signal and the measuring signal for producing an output signal corresponding to the relative values of the reference signal and the measuring signal. A first optical path between the light source and the first phototransistor and a second optical path between the light source and the second phototransistor are both disposed in rinsing water and the length of the first optical path is set to be longer than the length of the second optical path.
