Of the pollutants in domestic wastewater, detergents used for washing account for a large proportion, and future washing machines will need to be environmentally friendly.

で汚れをミセルとして安定に存在させ、汚れが布に再び
付着するのを防ぐ再汚染防止作用がある。The cleaning effect of the detergent is mainly due to the surfactant. The surfactant is adsorbed on the surface of the cloth to separate the cloth and the dirt, and at the interface between the dirt and a solvent such as water, the dirt is stably present as a micelle in the liquid. Has a function of preventing recontamination, which prevents the redeposition on the cloth.

は、水ではほとんど落ちず特に問題である。Further, the separation of the dirt from the cloth itself is
Water alone is possible to some extent and can be increased by using warm water or electrolyzed water. However, there was a problem that recontamination cannot be prevented by itself. Hydrophilic stains such as mud stains are easily removed by washing with water, so even if reattachment occurs, there is no problem if the rinse is sufficient. On the other hand, when organic stains such as fats and oils, which are non-polar, have low solubility in water, and have low hydrophilicity, adhere to hydrophobic fibers such as polyester, they are hardly removed by water, which is a problem.
【０００６】また、洗剤を充分に使用して洗っている場

が残っていた場合、再汚染が起こる可能性がある。Even if the detergent is thoroughly used for washing, the concentration of the surfactant becomes low during the rinsing, and if stains remain, recontamination may occur.

As disclosed in Japanese Patent No. 168280, a method of washing co-washing attached fibers for adsorbing dirt with clothes,
As disclosed in Japanese Utility Model Laid-Open No. 5-9482, there is a method of passing washing water through a filter composed of a hydrophobic lipophilic adsorbent material, but neither of them considers regeneration of fibers or filters. . Further, under the condition that the surfactant is not used or only a small amount is used, the redeposition preventing agent contained in the detergent is not present, or the amount thereof is small, so that the amount of dirt adsorbed to the fiber or the filter is increased. Therefore, the fibers and filters tend to be disposable, which poses an economic problem.

の再生を行う。Re-contamination is a phenomenon in which dirt that has once left the cloth adheres again during washing and stains the cloth. In view of this, the present invention removes problematic stains from water with a cleaning unit made of an adsorbent so that the cloth does not adhere to clothes when washing and rinsing the cloth in a water bath. Further, by washing with warm water, electrolyzed water, etc., the purification unit is regenerated by the action of heat and alkali.

０．５程度が望ましい。An example of usage of the washing machine having the above-mentioned structure will be described. First, tap water is supplied to the electrolytic cell 10 from the water supply port 11. Then, as shown in FIG. 2A, when a DC voltage is applied using the power supply 23 so that the first electrode 14 serves as a cathode and the second electrode 15 serves as an anode,
Hydrogen is generated from the electrode 14 side, and electrolytic alkaline water is obtained from the electrolytic cell water intake 17. Oxygen from the second electrode 15 side,
Chlorine or the like is generated and electrolyzed acidic water is obtained, which is drained from the electrolyzer drain port 12. The flow path is switched by the three-way valve 13, the electrolytic alkaline water coming out from the electrolytic tank water intake 17 is caused to flow into the washing tub 2, and the electrolytic alkaline water is used for washing with a detergent. The higher the pH of the electrolyzed alkaline water is, the more effective it is to remove greasy dirt. However, when used for washing, the pH should be 1 to avoid discoloration of clothes.
About 0.5 is desirable.

て、洗濯槽２の上部へ返すように循環させる。During washing, the valve 7 is opened and the pump 8 is operated to allow washing water or rinsing water (hereinafter referred to as "washing water") to pass through the purification unit 9 and the three-way valve 13 to wash. Circulate back to the top of tank 2.

維も充分に洗浄できる。When the detergent is not used or the amount of the detergent used is small, since the interfacial tension of the cleaning liquid is not sufficiently lowered, a cloth made of hydrophobic fiber such as polyester floats on the water surface and becomes wet. May not penetrate and may not be washed sufficiently. Therefore, by circulating the wash water as in the present embodiment, the wash water can be sprinkled on the floating cloth, and the hydrophobic fibers that are hard to be removed by dirt can be sufficiently washed.

Especially adsorbs organic dirt. Examples of the adsorbent 18 include activated carbon and ion exchange resins. A synthetic adsorbent composed of a nonpolar resin such as polystyrene resin or polypropylene resin is excellent in adsorbing nonpolar dirt such as oil and fat that is insoluble in water. ,preferable.

き、再汚染を防止する。In washing with electrolytic alkaline water, in addition to physically removing stains with a stream of water or dissolving water-soluble stains with water, electrolysis lowers the interfacial tension to make stains easier to dissolve, It has the effect of saponifying a part of the stain and making it easily soluble in water. By these actions, the oil component eluted in water is removed by the purification unit 9 to prevent recontamination.

耐えうるｐＨ１４まで上昇させることが可能である。The purification unit 9 can be regenerated by using electrolytic alkaline water or electrolytic acidic water. In this case, electrolytic alkaline water is obtained from the electrolytic cell water intake 17 by applying a DC voltage so that the first electrode 14 serves as a cathode and the second electrode 15 serves as an anode as shown in FIG.
This alkaline water is caused to flow to the purification unit 9 side via the three-way valve 13. When removing the oil and fat adsorbed on the adsorbent 18, there is no limit to the pH value of the electrolyzed alkaline water, and electrolysis is performed with a larger current than when used for washing, or the flow rate of water is suppressed. Thus, it is possible to raise the pH of the resin of the adsorbent 18 to a level that the adsorbent 18 can withstand.

The scale can be removed by applying a voltage so that the second electrode 15 serves as a cathode, obtaining electrolytic acid water from the electrolytic cell water intake 17, and passing it through the purification unit 9. It is possible to remove the scale by passing the acidic electrolyzed water not only in the purification unit 9 but also in other parts such as the lower part of the water tank 1 where scale easily adheres. The cleaning of the purification unit 9 may be performed during a washing machine operation, such as during dehydration, in a step where water is not used, or after the washing is completed.
