the control unit of S3 judges the turbidity value range of turbidity value B of washing water once every t time interval, controls the indicator light to change alternately between 0, 1 and 2 in the judging process,
if in B1-B2, the control indicator light turns on 0,
if in B2-B3, the control indicator lamp turns on 1,
if in B3-B4, the control indicator light turns on 2.
The indicating device 103 may be formed by a plurality of layers of ring-shaped light sets, the number of the indicating lights on the inner layer is small, the number of the indicating lights on the outer layer is large, and each layer of indicating lights displays the same color and/or brightness.
In the process, at the initial stage of washing, when water enters, the quantity of the lighted indicating lamps in the lamp strip is small due to clear water quality; along with the increase of the washing time, the stains on the washed objects fall into water after being washed, so that the more the water is washed, the more dirty the water is, the indicator lamps in the lamp strip gradually increase according to specific turbidity values, and the number of the indicator lamps is increased; in the rinsing process, the washings are more and more clean, the light strip is gradually reduced along with the reduction of turbidity data, and the number of the indicator lights is reduced. In the washing process, the number of the lamps is changed and displayed to the user in real time, so that the user can know the washing condition of the washing machine at a glance.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
