Summary of the invention
The method that the object of the present invention is to provide a kind of brine electrolysis to wash, and in described washing, need not to adopt washing agent, or other electrolyte.
Purpose of the present invention can be achieved in the following manner, that is, slurry is carried out electrolysis, the pH value of the mechanical strength of control washing or time, brine electrolysis, and brine electrolysis carried out upgrading, can reach the washing machine method that need not washing agent on the practical significance.
To achieve these goals, technical scheme is the end of the present invention:
A kind of washing methods of the washing machine without washing agent is characterized in that described method comprises that washings are carried out electrolysis makes the pH value of described slurry reach 9.5-10.6.
Described pH value preferably reaches 9.5-10.6, and more preferably, described pH value reaches 10.4.
Described method comprises that running water enters electrolytic cell, and electrolysis goes out acid water and alkaline water in electrolytic cell, and alkaline water enters washtub, and acid water is discarded.After the alkaline water water inlet that activates by the water quality adjuster arrives designated water level, normally wash, washing finishes the back dewatering, enter rinse cycle: carry out rinsing for the second time, this moment, electrolysis went out acid water in electrolytic cell with the reversing of electrolytic cell, acid water enters washtub, go forward side by side a part of running water to reach the water level of setting, and the water inlet ratio of adjusting running water and acid water is finished whole washing process then to guarantee the concentration of acid water.
In described method, wash time at least 15 minutes.
The specific embodiment
As aforementioned, prior art comprises patent, propose some and need not the washing machine or the method for washing agent, even, the mode of washing with brine electrolysis has directly been proposed.
But, what prior art proposed is a conception of species substantially, promptly, utilize electrolysis, make the pH value of slurry improve, it also is the notion of a prior art that the slurry of high pH value can improve the rate of cleaning, still, the pH value that adopts what level is reasonably, i.e. balance electrolysis cost, wash time and do not injure material and but do not have concrete bibliographical information; What is more important, so-called without washing agent, under what kind of standard, carry out, because, if cast aside a comparative standard, such description is nonsensical, in fact, under the situation of standard without comparison, wash the clean ratio that also can reach certain merely with water, especially when being main dirt with ash, clean ratio can reach a quite high level.
Therefore, the present invention at first introduces comparative standard, the present invention is with the whole parts of introducing as content of the present invention of the national standard of washing machine, specifically, introduce the scourability test method, on this standard, describe the test method of scourability in detail, and support the creative needed whole parameters of the present invention just being based on that this standard obtains.
Specification of the present invention is not given unnecessary details described standard, only proposes an important comparative parameter of the present invention with regard to this standard, and clean ratio is 0.7, and research of the present invention is mainly carried out around this point.
Table 1, table 2 have been listed process of the test of the present invention and experimental condition in detail, specifically referring to table 1, table 2.
The comparison of washing methods of the present invention and prior art

(4) numerical value is the mean value of test of many times in the experiment condition;
(5) the test type is two-power washing machine XQS52-78
From table 1, can analyze and draw:
(1) owing to the objective of the invention is not use washing agent, therefore, the most direct and what have comparativity is the comparison of table 1 and the comparison of table 2, the result of the test of table 1 shows, washing methods of the present invention, can access 0.7 clean ratio, compare, can be called the washing methods that need not washing agent veritably with standard;
(2) as aforementioned, need not washing methods of the present invention the time, do not adopt washing agent, have 0.45 clean ratio; The clean ratio that can't reach GB requires
(3) further, his-and-hers watches 2 compare, and the present invention has manifested 0.70 clean ratio, has satisfied basic washing requirement equally;
On the basis that obtains needed clean ratio, further, the method for the invention is after electrolysis obtains needed wash conditions.
Owing to do not use washing agent, therefore, the composition that has emollescence in the washing agent of prior art does not exist yet, therefore, in the method for the invention, increase modifiedly, make wash liquid be applicable to the washing of fabric more, make it to avoid fully the additional defective that may bring without washing agent.
Among the present invention, the electrolysis unit of employing (technology) can be any of prior art, for example listed electrolysis unit in the background technology of specification; And quality-adjusting device, or to be referred to as upgrading water device (technology) also can be any of prior art, for example, the technology disclosed in CN2485322, CN1314510, the CN2358094 all can be introduced directly into the present invention.
