Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a consumer or industrial cleaning apparatus for clothes, tableware, medical instruments and the like, and more particularly to a cleaning apparatus such as a washing machine and a dishwasher with improved cleaning efficiency.

[0002]

2. Description of the Related Art A washing machine used for washing clothes, etc., generates water flow in a washing tub to wash and rinse the laundry, and spins the tub containing the laundry at a high speed for dehydration. This is a device for washing clothes. Since the neutral detergent conventionally used in this type of washing machine has a large adverse effect on the environment, it has been proposed to avoid the use of the neutral detergent or reduce the amount thereof. However, if the amount of the neutral detergent used is less than the prescribed amount or if soap having a low detergency is used instead of the neutral detergent, there is a problem that the detergency is insufficient and unwashed residue is likely to occur. As described above, there is a limit to the reduction of the amount of detergents used, and there is a demand for improvement in detergency by means not directly related to detergents.

Water used in a washing machine includes rinsing water in addition to washing water used with a detergent, and rinsing water is also important for enhancing the washing effect of laundry, but tap water is usually used. Then, the laundry is washed with the washing power of the tap water. As a means for increasing the washing effect of washing water and rinsing water used in such a washing machine, electrochemical treatment of these waters has been proposed. When electrochemical treatment is carried out, acidic water is produced on the anode chamber side and alkaline ionized water is produced on the cathode chamber side, and these acidic water and alkaline ionized water have a sterilizing action and a detergency. Therefore, when tap water is replaced with acidic water or alkaline ionized water, the cleaning effect is improved, and washing should be carried out without changing the cleaning effect even if the detergent is replaced with soap or the amount of detergent used is reduced. You can Besides washing with a washing machine,
There is a device for cleaning using cleaning water, for example, a dishwasher. In the case of a dishwasher, tap water is used as washing water, and acidic water or alkaline ionized water produced by electrochemical treatment is not used. A dishwasher is a device that sprays a water stream to wash dishes, and it is more difficult to remove dirt than a washing machine, and more effective washing is required.

[0004]

The electrodes used in the production of functional water such as acidic water and alkaline ionized water by the electrochemical treatment described above generally use lead oxide, tin oxide, graphite, amorphous carbon, etc. as the anode. As the cathode, lead, iron, platinum, titanium, carbon and the like are used, and as the anode, it is preferable to use precious metals such as platinum and iridium and oxides thereof. However, even if these materials are used, it is known that when electricity is applied, the materials are consumed depending on the current density and the time of application, and elute into the electrolytic solution. Since there is no point in performing electrochemical treatment, an electrode having more excellent corrosion resistance is desired.

As such an electrode, a noble metal electrode having a substrate coated with platinum or another platinum group metal or its oxide is known. The use of this noble metal electrode enables stable functional water generation with almost no elution of the electrode substance, but it is insufficient in terms of yield and selectivity, and further expensive is an obstacle to practical use. There is. A conductive diamond electrode has been proposed as an electrode cheaper than the noble metal electrode. While graphite and amorphous carbon materials, which have been known as electrode materials from the past, are subject to severe wear during anodic polarization, conductive diamond has thermal conductivity, optical transparency, and durability against high temperatures and oxidation. It is excellent, and its electrical conductivity can be controlled by doping.

As an electrode for electrochemical use, the stability of diamond in acidic electrolyte has been reported [Journal of Elec.
trochemical Society, Vol.141, p.3382 (1994)], suggesting that it is far superior to other carbon materials, and further treating organic wastewater with electrodes having conductive diamond (US Pat. No. 5,399,247). (Specification) and generation of functional water (JP-A-9-268395, JP-A-2001-192874). Although these conductive diamond electrodes are excellent as described above, their use has not been sufficiently investigated. On the other hand, recently, a washing machine that has a built-in electrolytic cell and uses washing water containing generated electroactive species to wash clothes and disinfects and removes and decomposes contaminants has been put on the market. There is an advantage that the amount can be saved. However, since the cleaning water generated in this electrolytic cell is produced by using the above-mentioned metal or carbon electrode, elution of the electrode substance is unavoidable, which is not desirable as cleaning water for washing machines. is there. It is an object of the present invention to provide a cleaning apparatus that can generate cleaning water containing substantially no impurities by using a cheaper and more stable electrode and perform various cleanings using this cleaning water.

[0007]

According to the present invention, at least one of the surfaces has a washing water producing section containing an anode and a cathode containing conductive diamond, and raw water is electrochemically produced in the washing water producing section. It is a cleaning device characterized by performing treatment to generate cleaning water and using the cleaning water to clean an object to be cleaned, and can be applied to a washing machine or a dishwasher.

The present invention will be described in detail below. In the present invention, a cleaning water generator for electrochemically generating functional water is installed, and in a cleaning device for cleaning an object to be cleaned with the generated cleaning water, among the anode and cathode used in the cleaning water generator,
At least one of the surfaces contains conductive diamond on its surface so that cleaning water can be produced inexpensively and efficiently. At this time, since the anode and / or the cathode contain conductive diamond on the surface thereof, the elution of the electrode substance does not substantially occur, and washing water having no impurities can be obtained. Conductive diamond is inert to water splitting,
Cleaning water can be obtained efficiently. Furthermore, since conductive diamond is obtained by decomposing an organic compound, it is inexpensive and can be used economically.

The generated washing water is used in a washing machine such as a washing machine or a dishwasher, and thus, compared with the case where functional water generated in an electrolytic cell having an ordinary electrode is used, Cleaning can be performed more efficiently. The electrolytic bath for generating the cleaning water (cleaning water generation unit) may be built in the cleaning device or may be connected via a water supply line and installed outside. Further, as in the conventional washing machine, a filter may be additionally provided for removing impurities in the circulating wash water.
Further, when ultrasonic cleaning is used together, mass transfer is promoted and the cleaning effect is further improved.

As the raw water for cleaning, tap water, well water, etc. can be used, but they have the drawbacks that they have a low conductivity, the resistance loss in the cell voltage cannot be ignored, and the effective surface of the electrode reaction is limited. . Therefore, it is desirable to dissolve salts such as sodium sulfate, potassium sulfate, sodium chloride and potassium chloride to increase the conductivity. The preferred salt concentration is
It is 0.01 to 100 g / liter. In the case of a treatment target containing a large amount of metal ions, such as tap water, well water, and seawater, hydroxides and carbonates may be deposited on the cathode surface, and silica may be deposited on the anode surface to hinder the reaction. In order to prevent this, a reverse current may be applied at appropriate intervals (1 minute to 10 hours) to detach the precipitate.

The conductive diamond electrode used is preferably formed on a current collector such as a metal. Diamond electrodes are hot filament method, CVD method, microwave plasma CVD method, plasma arc jet method and PVD.
It can be formed by a method or the like. The microwave plasma CVD
In the method, the raw material is radicalized by a microwave having a frequency of 2 to 3 GHz. Even when the conventional synthetic diamond powder by ultra-high pressure is used, it may be fixed by a binder such as resin or ceramics or while forming an oxide by firing. The volume fraction of conductive diamond reduces electrical resistance and increases the effective electrode area.
30% or more is desirable.

A part of the non-diamond component is generated depending on the method of synthesizing diamond and may be contained in the diamond component. These non-diamond components and other non-corrosion resistant carbon components are consumed by being dissolved in the electrolytic solution and have little practical effect, but it is desirable to remove them by acid washing or the like before use. There is no problem if the material of the current collector is conductive, but plates such as titanium, niobium, tantalum, silicon, carbon, nickel, tungsten carbide, zirconium, and silver, punched plate, wire mesh, powder sintered body, metal fiber A sintered body or the like can be preferably used. An intermediate layer may be formed between the electrode or current collector and the substrate for the purpose of improving the density and protecting the substrate. The intermediate layer includes carbides and oxides. The roughening of the substrate surface contributes to the increase in adhesion and reaction area. If diamond powder is used as nuclei to adhere to the substrate surface during this roughening, it contributes to uniform growth of the diamond layer.

The hot filament method, which is a typical diamond electrode manufacturing method, will be described. Keeping organic compounds such as alcohol as a carbon source in a reducing atmosphere such as hydrogen gas, the temperature at which carbon radicals form filaments 1800-
Heat to 2400 ° C. Then, a current collector and an electrode substrate are arranged in the atmosphere so that the temperature range (750 to 950 ° C.) in which diamond is deposited is reached. At this time, the desired concentration of the raw material organic compound with respect to hydrogen is 0.1-10% by volume, and the supply rate is 0.01-10 liters / minute depending on the size of the reaction vessel.
The pressure is 15-760 mmHg. Usually 0.0 on the electrode substrate.
Diamond fine particles having a particle size of 1-1 μm are deposited. The thickness of the diamond layer may be adjusted by increasing or decreasing the operating time, and the thickness is preferably 0.1-50 μm for the purpose of preventing the electrolyte solution from entering the electrode substrate.
It is particularly preferable that the thickness is μm.

In order to obtain good conductivity, it is indispensable to add a trace amount of elements having different valences, the preferable content of boron or phosphorus is 1-100000 ppm, and the more preferable content is 100-10000 ppm. Is. Specific compounds include boron oxide and phosphorus pentoxide, which have low toxicity. DLN (diamon), which is a composite material with amorphous silicon oxide
You can also use d-like nano-composite). The diamond particles thus produced may be used as a normal electrode by supporting them on a substrate or a power feeding body as described above, but when used as a three-dimensional electrode in a fluidized bed or a fixed bed, the reaction area increases. The processing capacity is improved.

When this conductive diamond is used as an anode, hydrogen ions are generated in the anolyte to produce acidic water as in the case of a noble metal electrode or the like. When hydrochloric acid is added to the anolyte, hypochlorous acid is produced, and when sulfuric acid is added, persulfuric acid is produced. When the above-mentioned conductive diamond is used as a cathode, hydroxide ions are generated in the catholyte to generate alkaline ionized water as in the case of a noble metal electrode, and hydrogen peroxide, ozone or superoxide radicals are generated depending on the conditions. In either case, functional water having bactericidal power is generated, or contaminants such as organic substances are decomposed to be regenerated into clear water. As shown in the examples below, E. coli, which is one of E. coli, has an excellent bactericidal activity. Judging from the rate of decrease in the number of Coli colonies. The cleaning apparatus of the present invention enables processing in a short time.

In order to stably maintain active substances in acidic water and alkaline ionized water produced by electrolysis of raw water, it is desirable to divide the electrolytic cell into an anode chamber and a cathode chamber by using a neutral diaphragm or an ion exchange membrane. . Fluororesin-based or hydrocarbon-based ion exchange membranes not only prevent the ions generated at the anode or cathode from being consumed at the opposite electrode, but also accelerate electrolysis when the conductivity of the liquid is low. . Commercially available ion-exchange resin particles can be used as the solid porous material having ion-exchange ability, and as the hydrocarbon-based resin, there are styrene-based, acrylic acid-based, and aromatic polymers.
The use of PTFE-based fluororesin is desirable. Considering the uniform dispersion of the liquid and the resistivity, the porosity is preferably 20 to 90% and the material size is preferably 0.1 to 10 mm. When electrolysis is carried out using such a diaphragm, acidic water (anolyte) and alkaline ionized water (catholyte) are obtained in a state where they are separated from each other. For example, acidic water is supplied to the cleaning unit, and then alkaline ionized water is supplied. When water is supplied, the oxidative cleaning and the alkaline cleaning are repeated to enable efficient cleaning.

As the material of the electrolytic cell which can be used in the present invention, hydrocarbon resins such as polypropylene, polyvinyl chloride and polyethylene, glass lining materials, carbon, titanium having excellent corrosion resistance, stainless steel and PTFE resin are preferable. The electrolysis conditions are such that the temperature is 5 to 80 ° C., preferably 5 to 40 ° C., and the current density when using an ordinary electrode is 0.001 to 10 A / dm ² . It is desirable to reduce the resistance loss by making the distance between the electrodes as small as possible, but considering the pressure loss of water supply, it is preferably 0.5 to 10 mm in order to maintain a uniform flow distribution.
