Present embodiment is only at the detection design of relevant cloth amount.Survey for the cloth quality inspection, Fig. 3 also is suitable for from setting procedure, but the mensuration of described electromotive force wave number is changed into the wave amplitude that detects each electromotive force waveform, and calculating autotomys in each outage at interval establishes the beginning finishes the wave amplitude of electromotive force waveform to outage pad value by cable---the wave amplitude of last 1 the electromotive force waveform before the wave amplitude of the 1st the electromotive force waveform in outage beginning back finishes with outage poor; Change the output input relation of cloth matter and described electromotive force wave amplitude decay and the acceptability limit of described electromotive force wave amplitude decay in the table 1 into.Also be provided with sensors such as cleaning solution turbidity and temperature as washing machine, and its output is connected with the I/O mouth of single-chip microcomputer 15, also can sets up as cloth amount or cloth quality inspection and survey, satisfy and improve the requirement that it detects stability similarly from setting procedure.Can obtain the input/output relation and the acceptability limit value of concrete data by experiment, be organized in the program of single-chip microcomputer 15.
Detection of the present invention is to carry out after the washing machine water filling.For showing the superiority of the present invention, the fuzzy control automatic washing machine of a rated capacity 5kg has been carried out transforming the contrast experiment of front and back in the anhydrous detection of technology formerly.
Be that actuating motor 6 is interrupted energising with certain cycle under anhydrous situation before this washing machine is transformed, photoelectric isolating circuit input through being connected on motor 6 power supply terminals betides outage motor-induced electromotive force wave number at interval, to this wave number cloth amount according to the rules or the output input relation calculating of cloth matter and electromotive force wave number, obtain cloth amount testing result.With the standard clothes amount detection of each cloth amount shelves to wave number be:
Shelves number no clothing 1234
After this washing machine transformation for there being actuating motor 6 under the situation of water to be interrupted energising with certain cycle, photoelectric isolating circuit input through being connected on motor 6 power supply terminals betides outage motor-induced electromotive force wave number at interval, to this wave number cloth amount according to the rules or the output input relation calculating of cloth matter and electromotive force wave number, obtain cloth amount testing result.With the standard clothes amount detection of each cloth amount shelves to wave number be:
Shelves number no clothing 1234
As can be seen, adjacent shelves under anhydrous situation (refer to not have clothing and the 1st grade, or the 1st grade and the 2nd grade, or the 2nd grade and the 3rd grade, or the 3rd grade and the 4th grade) difference of detected wave number mostly is 1 most, (for example do not have clothing and the 1st grade, perhaps the 3rd grade and the 4th grade) during especially for lower or higher cloth amount shelves indifference.Wherein, for the 1st grade of water level, the 2nd grade of water level, perhaps, the setting of the 3rd grade of water level or the like, inconsistent at different types, different factory settings, but, be a technique known general knowledge for a person skilled in the art, designated water level is to set arbitrarily by design, as reference, attach the gear of a certain model washing machine and the table of comparisons 2 of corresponding water level behind this specification, only supply teacher's auditor reference.
Same adjacent shelves (for example being both the 1st grade and the 2nd grade of detection) detected wave number poor is under anhydrous situation 2 times having under the situation of water at least.As seen, having under the situation of water than much higher detection sensitivity is arranged under anhydrous situation.The normal detection of this detection sensitivity influence is for example having under the situation of water, and the shelves number that the cloth amount detects can design 4 grades; Under anhydrous situation,, can only design 3 grades because the difference of the detected wave number of adjacent shelves is zero during lower or higher cloth amount shelves.This detection sensitivity also influences from the design of adjusting measuring ability, for example the difference owing to the detected wave number of adjacent shelves mostly is 1 most under anhydrous situation, so the cloth amount that is difficult to design as embodiment of the invention table 1 detects the input-output data relation, obviously influence is from the stability of adjusting and detecting.
