SUMMARY OF THE INVENTION A composite ionic water washing / washing system according to the present invention comprises a washing / washing means, an ionic water generating means for generating alkaline ionic water and acidic ionic water, and a composite ionic water as a cleaning liquid. To form
There is a composite ion water mixing means to be supplied to the washing / washing means.

The composite ionic water mixing means includes an alkaline ionic water valve, an acidic ionic water valve, and an alkaline ionic water valve so as to form a composite ionic water by mixing the alkaline ionic water and the acidic ionic water.
And an ion water mixing pump to which these are connected. With such a configuration, it is possible to form composite ionized water in which alkaline ionized water and acidic ionized water are mixed at a volume ratio of about 1: 1 and composite ionized water mixed in an optimum ratio for the laundry. By opening and closing the alkaline ionized water valve and the acidic ionized water valve, a composite ionized water having a required mixing ratio can be formed. In this case, it is also effective to improve the detergency by opening the acidic ion water valve after opening the alkali ion water valve so that the acidic ion water is not supplied to the washing / washing means first.

An ionic water mixing pump connected to an alkaline tank and an acidic tank, a flow control valve connected to the ionic water mixing pump, and a pH adjuster for using ionic water generated by ionic water generating means as a pH adjusting liquid of the washing wastewater. The valve and a pH adjusting tank connected to the valve via an ion water passage constitute drainage mixing means. Open the pH control valve and close the composite ion water valve to neutralize the washing wastewater through the drainage channel.

In order to further improve the cleaning effect, after a lapse of time that the complex ionized water permeates the object to be cleaned, or
At the same time that the washing liquid is supplied to the washing / washing means, an additive mixing means for supplying sodium metasilicate or sodium carbonate to the washing / washing means is connected to the washing / washing means.

For some objects to be cleaned, it is better to use alkaline ionized water for cleaning instead of composite ionized water, so that the alkaline water can be efficiently purified by the ionized water generating means corresponding to the case of using alkaline ionized water. To make
Instead of the additive mixing means, a pre-process additive mixing means for directly introducing sodium metasilicate or sodium carbonate to the ionic water generating means and mixing them is provided.

In order to further improve the washing effect, an activator mixing means for adding an alkylethanol-based nonionic activator to complex ionized water to which sodium metasilicate or sodium carbonate is added is connected to the washing / washing means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. The washing / washing means 2 is, for example, a washing machine for washing clothes, and includes a washing tub 2a, a basket 2b, and a drain solenoid valve 4 that opens and closes a drain channel 5 for draining laundry drain.

The ionic water generating means 6 is supplied with tap water through a water tap 8 and salt is added by a salt water tank 10.
Electrolysis produces alkaline ionized water and acidic ionized water. The generated alkaline ionized water 14 is stored in the alkaline tank 15 via the passage 12, and the acidic ionized water 1
6 is stored in the acidic tank 17 via the three-way valve 50 connected to the passage 13 and the passage 13b. Three-way valve 50 is in passage
It is possible to switch between the case of leading from 3 to 13b and the case of leading from passage 13 to 13a. Both tanks have a first sensor 18 at the bottom as a sensor for detecting the water surface.
Since the second sensor 19 is provided on the upper part, automatic adjustment operation can be easily performed so that a fixed amount of alkali ion water and acidic ion water is filled. The tanks 15 and 17 are provided with drain pipes 14d, 16d, and
They are connected via valves 22a and 22b.

Alkaline tank 15 of ionic water generating means
In the composite ion water mixing means 40 connected to the ionic water tank 17 and the ionic water mixing pump 40, the ionic water mixing pump 43 is connected to the ionic water passages 20a and 20b via an alkaline ionic water valve 21a and an acidic ionic water valve 21b. Water passages 20a and 20b are connected to an alkaline tank 15 and an acidic tank 16, respectively. Ion water mixing pump 4
Numeral 3 is connected to the washing / washing means 2 through a passage 25 through a composite ion water valve 27. When the valve 27a is opened and the alkaline ionized water valve 21a and the acidic ionized water valve 21b are opened and the ion water mixing pump 43 is operated, the alkaline ionized water 14 and the acidic ionized water 16 are simultaneously drawn from the respective tanks. Then, they are mixed to form composite ionized water and supplied to the washing / washing means 2.
(At this time, a pH adjustment valve 28 described later is closed.)
The valves 21a and 21b are flow rate control valves capable of controlling the flow rate. When the flow rate is equal, the composite ionic water has a volume ratio of alkaline ionic water to acidic ionic water of 1
The washing effect when an additive is added to the mixture becomes one-to-one composite ion water. The washing effect when the additive is added will be described later. However, the surface tension of ionized water is smaller than that of tap water, so the penetration power as washing water is stronger. It was confirmed that.

When the flow rates of the flow rate control valves 21a and 21b are adjusted and passed, the complex ion water is formed at an arbitrary mixing ratio, so that the one having an optimum mixing ratio for the material to be cleaned can be selected. In addition, the cleaning effect can be improved. When the composite ionized water is converted into acidic ionized water by closing the valve 21a, after washing and draining, the acidic ionized water is removed from the washing tub 2.
The laundry is sanitized by supplying it to the laundry a and rinsing it.

Depending on the material of the object to be cleaned, the cleaning effect is drastically reduced when immersed in acidic ionic water from the beginning. Therefore, when adjusting the flow rates of the valves 21a and 21b and passing the same, the alkali ion water valve is first used. By opening the valve 21a and then opening the acidic ion water valve 21b, it is ensured that only the acidic ion water is not supplied to the laundry first. As described above, it is also effective to perform the automatic operation so that the valves 21a and 21b operate in the open / close order.

The drain mixing means is connected to the p-channel connected to the drain channel 5.

5, acid tank 17, ion water mixing pump 43, alkali ion water valve 21a, acid ion water valve 21b,
It is composed of ion water passages 20a and 20b. In order to neutralize the liquid in the pH adjustment tank, acidic or alkaline ionized water is pumped up by the pump 43, and the pH adjustment valve 28 is opened.
The composite ion water valve 27 is closed and drained to the drain channel 5 to neutralize the washing drainage.

As described above, the ionic water generating means to which tap water is supplied is connected to the composite ionic water mixing means,
Further, it is connected to the washing / washing means and further connected to the pH adjusting tank 35 through the drain passage 5, and the neutralized waste water is drained by opening the drain valve 36, so that no pollution problem occurs.

The additive mixing means 31 is a means for containing sodium metasilicate or sodium carbonate, connected to the washing tub 2a through a valve 33, and for mixing sodium metasilicate or sodium carbonate with washing water in the washing machine. .
A pre-process additive mixing means 51 that is switched and used in some cases
Is connected to the ion water generator 6 via a valve 52 in place of the additive mixing means 31, and mixes sodium metasilicate or sodium carbonate with tap water in the ion water generator 6 to generate strong alkaline ion water. Means to
The selection is switched according to the material of the object to be cleaned. In this case, the three-way valve 50 switches so that the cleaning liquid flowing out of the passage 13 flows into the passage 13a. As described above, the three-way valve is switched from the passage set from the passage 13 to the passage 13b and connected to the acid tank when the pre-process additive mixing means is used.

The activator mixing means 32 is connected to the washing tub 2a via a valve 34, and is a means for mixing the alkylethanol-based activator into the washing water in the washing machine, and for further improving the washing effect. It has the effect of improving the penetrating power that penetrates into the fiber of the object to be cleaned, and at the same time has the effect of preventing the contaminant from re-adhering to the object to be cleaned after peeling.

The effect of the washing liquid will be described below with reference to the graph of FIG. Indicated by ■ are washing liquids in which the amount of sodium metasilicate added as an additive is changed from zero to 1% (as shown on the horizontal axis of the graph) based on the composite ionized water of the embodiment according to the present invention. The vertical axis shows the washing rate as the washing effect when the contaminated cloth is washed. In addition, the result of washing using the same detergent as a comparative washing liquid with the same additive added to a standard detergent base of tap water is indicated by a triangle. One commercially available detergent is selected as a standard detergent. The stained cloth used for the test is a white cloth having a reflectance of 76.1%, which is stained under the test conditions shown in FIG. Other washing conditions are the same for both washing liquids. The advantage of the washing rate in the embodiment of the present invention is as follows.
It was confirmed that it was remarkable in the case of exceeding 3%. Originally, composite ion water has a property of lower surface tension compared to non-ionized tap water. It was speculated before this experiment that if this property was used for washing, it would be possible to utilize the power that penetrates between the fiber and contaminants attached to the fibers of clothing, etc. Has demonstrated this, confirming the cleaning effect of composite ionized water.

Next, the operation of the wastewater mixing means will be described.

[0021]

The ionized water has a superior detergency due to its low surface tension and good permeability as compared with conventional tap water. As a result of finding this fact,
A washing / washing system utilizing complex ionized water has been realized,
Furthermore, a system was realized in which additives and activators were mixed as the optimum cleaning liquid for the material to be cleaned, and composite ion water was easily supplied to perform cleaning. By carrying out the present invention, dry cleaning using a solvent can be shifted to water washing, and since a general detergent that pollutes rivers is not used, washing without causing a pollution problem can be performed. In addition, since the washing effect is improved, environmental protection is improved. And the economic effect is great.
