Description

Clothing is cleaned the clean automatic washing machine that promptly stops that promptly stops method and use this method
Technical field
The present invention relates to a kind of washing machine, specifically is that a kind of can judging whether automatically cleaned and controlled the clean clean automatic washing machine that promptly stops that promptly stops method and use this method of clothing of laundry processes with this.
Background technology
Although automation, the intelligent degree of existing washing machine have developed into quite high level, even can carry out the remote control laundry with phone, but, also do not discern the washing machine whether clothing is cleaned, 99117891.2 of application numbers are called [washing machine that can discern clothes weight and clean level automatically], and the determination methods of the described clean level of this patent is as follows: (1) is according to the first minimum dosage that adds washing agent, slurry of clothes weight decision; (2) after washing a period of time, read the output valve of photoelectric sensor, determine the clean level of clothing, again according to the recruitment of clothes weight and clean level decision washing agent, slurry and wash time and whether repeatedly wash according to the variation of this value; (3) can and whether carry out repeatedly rinsing according to clothes weight and clean level decision rinsing water amount, rinsing time during rinsing.
Must point out that the determination methods of the disclosed clean level of this patent remains in following defective:
1, in the method (2) " after washing a period of time; read the output valve of photoelectric sensor; determine the clean level of clothing according to the variation of this value, again according to the recruitment of clothes weight and clean level decision washing agent, slurry and wash time and whether repeatedly wash "; Wherein " determine the clean level of clothing according to the variation of the output valve of photoelectric sensor " and be to compare with the data of prior setting, actual conditions are, raising along with the washing clothes clean level, the amount that spot on the clothing is dissolved in the washings is many more, the light transmittance liquid of washings is poor more, and along with the serious light transmittance of the dirty degree of the stolen goods of washing clothes is poor more, fading of washing clothes also influences light transmittance, and from different places, the water quality difference, the data of its test are also different, therefore, compare with the data of prior setting and can not reflect correctly whether clothing is washed totally.
2, according to " recruitment of wash time and whether repeatedly wash " this condition, the numerical value that can draw the light transmittance that sets in advance should be than higher, after washing a period of time, the numeric ratio of the output valve of the photoelectric sensor that reads and the prior light transmittance of setting, this application does not provide the concrete data of setting value, difference, therefore, decide the recruitment of wash time and whether repeatedly wash, can't realize with this.
