Description

The present invention relates to a cleaning liquid generating device for cleaning and coating the surface of vehicles, structures and the like, and a cleaning / coating liquid generating device. More specifically, dirt adhering to the surface of a surface exposed to the outside air, such as a painted surface of a vehicle outer panel, an outer wall surface of a building, a window glass surface, and a civil engineering structure such as a bridge or a curb of a road. The present invention relates to a cleaning liquid generating device and a cleaning / coating liquid generating device that exhibit a "cleaning effect" that removes water and a "coating effect" that makes the surface of an object less likely to get dirty.

As a means to easily remove dirt adhering to the surface exposed to the outside air on the painted surface of the vehicle outer panel, the outer wall surface of the building, the window glass surface of the building, and the outer surface of civil engineering structures such as bridges and curbs of roads. , Various cleaning solutions have been proposed. However, vehicles used outdoors, outer walls of various structures, windowpanes, etc. are constantly exposed to the outside air, so even if they are cleaned, they will become dirty again in an extremely short period of time, and they will be re-cleaned within a short period of time. There is a problem of being forced.

In addition, dirt adhering to the outer panel of the vehicle, the outer wall of the building, the window glass of the building, etc., which is constantly exposed to the outside air, is extremely persistent and cannot be easily removed, so that there is a problem that it takes time and effort to clean. Further, when the persistent stains adhering to these surfaces are strongly rubbed off with a brush or the like, there is a risk that the surfaces may be scratched. Therefore, for example, there is a problem that dirt on the outer panel of a private car (for example, a luxury foreign car, a sports car, a vintage car), which is treated carefully, cannot be easily removed.

The applicant elutes slightly water-soluble silicon oxide from the ceramic composite to generate an aqueous solution of silicon oxide, and the silicon oxide solution is poured onto the surface of an outer plate of a vehicle or the like to be brought into contact with the surface of the outer plate. We have proposed a system having a ceramic composite, which is a method for forming a transparent thin film of eluted silicon oxide (Patent Document 1). Further, in a coating liquid generator, when producing cleaning water for forming a silica film, it has been proposed that the cleaning water is passed through a magnetic field or ultraviolet rays in order to activate the cleaning water (Patent Documents 2, 3, etc.). ..

On the other hand, in order to reduce the amount of detergent used when washing clothes and the like, a washing machine that electrolyzes the laundry while electrolyzing the washing water with an electrolytic device has also been proposed (for example, Patent Document 4). This is to decompose the dirt and sterilize the fungi with active oxygen or the like generated by electrolysis of the dirt.

Japanese Unexamined Patent Publication No. 2011-518 Japanese Unexamined Patent Publication No. 2003-80184 WO2017 / 149741 Japanese Unexamined Patent Publication No. 2003-24692

However, the system described in Patent Document 1 has an advantage that a thin film (nano level) of silicon oxide can be coated on a large area from a ceramic composite using public tap water or the like, but the surface treatment of the object to be coated ( Cleaning) is a prerequisite, but there is no disclosure on this point. Further, as disclosed in Patent Document 3, a magnet that activates the washing water by a magnetic field and increases the elution amount of silicon oxide, which is slightly water-soluble in the washing water, is used to form a strong magnetic field. , UV lamp, etc. are required. For this reason, when working in the field, portable cleaning devices, coating devices, etc. equipped with magnets and UV lamps become heavier by equipping them with magnets and UV lamps, and the cost of magnets and UV lamps is high and complicated. There are various problems such as poor maintainability due to the structure.

Further, the electrolytic device for producing electrolyzed water of a washing machine described in Patent Document 4 is premised on being mounted on a washing machine or the like of clothes used indoors. The electrolyzer mounted on this washing machine is made compact by using a plate material for the electrode so as to have a large area in order to efficiently generate electrolyzed water. In this electrolytic device, the content of impurities, chlorine, etc. contained in the washing water differs depending on the area, etc., and the energizing current may change and cause a short circuit. Therefore, a protection circuit for protecting the energizing circuit is required ( See [0130] in the specification of Patent Document 3). If an electrically complicated and delicate circuit such as this protection circuit is provided, it is difficult to use it for a cleaning device or a coating device for vehicles, buildings, etc., which are often used outdoors.

[First Embodiment of Cleaning Liquid Generator]
FIG. 1 is a simplified diagram showing a schematic configuration of a cleaning liquid generator according to the first embodiment. As shown in FIG. 1, the cleaning liquid generating device 1 according to the first embodiment generally has a liquid reforming unit (cleaning liquid generating unit) 5 for generating a cleaning liquid, a tank 15 for storing the cleaning liquid, and a pump for pressurizing and circulating the cleaning liquid. It is composed of a pump 17 to be operated, a flow path of cleaning liquid 31 to 35, and the like. The liquid reforming unit 5 includes a tubular flow path (cylindrical body) 5a in which a space is partitioned inside the main body, a first electrode portion 11 and a second electrode portion 11 arranged opposite to the inside. It is composed of electrode portions 12, and includes a power supply 7 that loads a voltage between the two electrodes. The tank 15 is for temporarily storing the cleaning liquid generated by the liquid reforming unit 5. The pump 17 supplies or circulates the cleaning liquid to the liquid reforming unit 5. The tank 15, the pump 17, and the tubular flow path 5a are connected by flow paths 31 to 35, which are pipes, and the cleaning liquid is circulated between them.

Hereinafter, each element constituting the cleaning liquid generation device 1 will be specifically described. The tubular flow path 5a is a tubular body made of engineering plastics such as a hard polyvinyl chloride pipe having corrosion resistance, and the inside is hollow. The tubular flow path 5a is provided with a cylindrical space in which a liquid (for example, public tap water) that is a source of the cleaning liquid generated in this example smoothly flows. At both ends of the tubular flow path 5a, a liquid inlet 21 for allowing the liquid to flow in and a liquid outlet 22 for causing the liquid to flow out are arranged at intervals in order to allow the liquid to flow into the cylindrical space. Is placed. In the tubular flow path 5a, rod-shaped first electrode portions 11 and second electrode portions 12 are fixedly arranged to face each other at both ends thereof. The first electrode 11 and the second electrode 12 are linearly arranged in the space in the tubular flow path 5a and are exposed in this space. To be precise, the rod-shaped first electrode 11 and the second electrode 12 are arranged so that the axis line and the center line of the tubular flow path 5a are parallel to each other. The liquid inlet 21 opened at one end of the tubular flow path 5a is arranged in the vicinity of the first electrode portion 11.

The liquid outlet 22 opened at the other end of the tubular flow path 5a is arranged in the vicinity of the second electrode portion 12. That is, the tubular flow path 5a is not a container for storage such as a tank, but a housing for electrolyzing a liquid such as water inside the container. For this reason, the internal space of the tubular flow path 5a may be any one as long as the liquid can flow, and may have a prismatic internal space such as a hexagon or a quadrangle even if the cross-sectional shape is not cylindrical. Both ends of the tubular flow path 5a of this example are closed so that the liquid does not leak out. One ends of the first electrode portion 11 and the second electrode portion 12 are fixed to both ends of the tubular flow path 5a, respectively. The first electrode portion 11 and the second electrode portion 12 are each connected to the DC power supply 7 via a cable. The distance between the first electrode portion 11 and the second electrode portion 12 differs depending on the DC voltage used (5 to 30 V in this example), but is arranged at such an interval that a short circuit does not occur and an overcurrent does not flow. .. For example, the water of public tap water that has flowed into the internal space of the tubular flow path 5a from the liquid inlet 21 flows in one direction of the liquid outlet 22 inside the tubular flow path 5a.

In this flow process, water comes into contact with the first electrode portion 11 and the second electrode portion 12, and when a voltage is applied, the water is electrolyzed into electrolyzed water containing active oxygen, hydrogen, and the like. be changed. As a result, water such as public tap water is changed to a cleaning liquid having a cleaning function as electrolyzed water, and is discharged from the liquid outlet 22. The liquid inlet 21, the liquid outlet 22, and the like provided in the tubular flow path 5a are opened and attached by plastic working, welding, adhesion, or the like. Although the tubular flow path 5a is made of synthetic resin in this example, it may be made of metal such as stainless steel having high corrosion resistance. The water reformed into electrolyzed water by electrolysis exits from the liquid outlet 22 and is stored in the tank 15 to become washing water. Normally, water that has been passed through the tubular flow path 5a only once does not become electrolyzed water having sufficient cleaning ability due to a small content of gas such as active oxygen, and therefore is circulated a plurality of times to be electrolyzed water. The washing water stored in the tank 15 is again pressurized by the pump 17, is pressurized and supplied to the liquid inlet 21 through the flow path 31, the flow path 32, and the flow path 33, and is circulated.

A typical example of "water", "liquid" or "liquid" in the present embodiment, that is, a typical example of the liquid that is the source of the cleaning liquid is "water" such as public tap water. However, the liquid applicable to the present invention is not necessarily limited to water such as public tap water, and may be clean river water. Furthermore, these waters are the main components, and a small amount of chemicals that are harmless to the environment (for example, degradable surfactants), salts, sodium hydroxide, chlorine gas, hypochlorite, etc. are added to the water to make electricity. A substance that promotes decomposition and production of sterilizing components may be added. In the present embodiment, the first electrode portion 11 is a rod-shaped electrode that functions as an anode (+ electrode). In this example, the rod-shaped first electrode portion 11 is made of a rod material which is a base material made of a conductive metal such as copper or titanium, and the surface thereof is coated with a thin film member serving as a catalyst by plating or the like. Is preferable. As the thin film member, for example, platinum, gold, titanium oxide and the like are preferable in terms of electrolysis characteristics. The second electrode portion 12 is also made of the same material and shape. It should be noted that the electrode member made of non-metal such as a graphite electrode and having conductivity can also be used.

One end of the first electrode portion 11 is exposed to the internal space of the tubular flow path 5a so as to come into contact with the liquid flowing in the tubular flow path 5a, and the other end is exposed to the end portion of the tubular flow path 5a. , It is insulated and fixed from the tubular flow path 5a. Further, the first electrode portion 11 is electrically connected to the positive electrode (+ electrode) of the power supply 7 via a cable. The second electrode portion 12 is fixed at a position facing the first electrode portion 11 and at the other end of the tubular flow path 5a. The second electrode portion 12 is a rod-shaped electrode that functions as a cathode (-pole) in the present embodiment. One end of the rod-shaped second electrode portion 12 is exposed to the internal space of the tubular flow path 5a so as to come into contact with the liquid flowing in the tubular flow path 5a, similarly to the first electrode portion 11. The other end is fixed to the end of the tubular flow path 5a so as to be insulated from the tubular flow path 5a. Further, the second electrode portion 12 is electrically connected to the negative electrode (-pole) of the power supply 7 via a cable.

That is, the rod-shaped first electrode portion 11 and the second electrode portion 12 are exposed in the internal space of the tubular flow path 5a so that the tip portions thereof face each other and come into contact with the liquid. It is located in. Further, as described above, the first electrode 11 and the second electrode 12 are arranged so that the axis line and the center line of the tubular flow path 5a are parallel to each other. Since the first electrode portion 11 and the second electrode portion 12 have a long rod shape, the liquid can be brought into contact with the first electrode portion 11 while flowing, and the contact time can be long, so that the efficiency of electrolysis is high. In the first embodiment, an electrode that functions as an anode (+ electrode) is provided on the upstream side and an electrode that functions as a cathode (-pole) is provided on the downstream side with respect to the liquid flowing inside the tubular flow path 5a. Although provided, the layout of the electrodes is not limited to this arrangement and may be reversed. That is, an electrode that functions as an anode (+ electrode) may be provided on the downstream side, and an electrode that functions as a cathode (-pole) may be provided on the upstream side.

The power supply 7 is used to apply a DC voltage to the liquid flowing inside the tubular flow path 5a. The power supply 7 is electrically connected to the first electrode portion 11 and the second electrode portion 12 via a cable. When the switch of the power supply 7 is energized while the liquid is flowing inside the tubular flow path 5a, the liquid (cylindrical flow) in which the two first electrode portions 11 and the second electrode portions 12 are in contact with each other. A voltage is applied to the liquid flowing inside the passage 5a), and as a result, the liquid is electrolyzed and reformed into a cleaning liquid. That is, when a voltage is applied, water is electrolyzed to become electrolyzed water containing active oxygen, hydrogen, and the like. The electrolyzed water is gradually imparted with a cleaning function to the original liquid, and the electrolyzed water is transformed into a cleaning liquid. The electrolyzed water contains active oxygen, hydrogen microbubbles, and nanobubbles, and the microbubbles and nanobubbles are known to have a function of removing stains such as stains on clothing and painted surfaces. Further, in the case of an aqueous solution containing sodium chloride in water, when it is electrolyzed, hypochlorous acid water containing hypochlorous acid (HClO) as a main component is produced. Hypochlorite water becomes electrolyzed water that also has a sterilizing effect, and in the case of stains that require sterilization, it is advisable to add a small amount of sodium chloride.

Further, as described above, the cleaning liquid generating device 1 has a pump 17, a flow path 31 to 35, and the like as a circulation means for circulating the liquid so that the liquid repeatedly flows in the tubular flow path 5a. ing. That is, in the first embodiment, the liquid (for example, public tap water) that is the source of the cleaning liquid is pressurized by the pump 17 and pumped. The liquid pumped by the pump 17 passes through the inside of the tubular flow path 5a via the flow paths 31 to 33, and further passes through the flow paths 34, 35 and the tank 15, and then passes through the tubular flow path. It repeatedly passes through 5a. By circulating the cleaning water in this way, the liquid that is the source of the generated cleaning liquid repeatedly flows in the tubular flow path 5a, and a cleaning liquid having strong cleaning power can be generated.

When the liquid is pumped in this way and the liquid is repeatedly circulated through the flow paths 31 to 35, the liquid repeatedly passes through the inside of the tubular flow path 5a, and a voltage is applied in the process to apply the original liquid. (For example, public tap water) is electrolyzed to generate hydrogen at the anode, oxygen at the anode, and the like to become a cleaning liquid that is electrolyzed water. That is, a liquid having a cleaning function is generated by repeatedly flowing a liquid (for example, public tap water) that is a source of the cleaning liquid through the tubular flow path 5a and applying a voltage. Since public tap water contains a small amount of ionized Ca, Fe, Al, etc., it conducts electricity. Further, for example, in water to which a small amount of salt is added to tap water, sodium hydroxide (NaOH), chlorine (Cl ₂ ), and hydrogen (H ₂ ) are generally generated by electrolysis. Since there is no partition partition separating the electrodes in the tubular flow path 5a of the above, these are not generated in high concentration. The components of the electrolyzed water of the present invention differ depending on the type of substance mixed in the water, but the electrolyzed water of the present invention mainly contains active oxygen, a cleaning effect due to fine bubbles of hydrogen, and an oxidizing action due to oxygen. The purpose is to clean the dirt on the surface by the reducing action of hydrogen.

[How to use the cleaning solution]
The cleaning liquid generated by the cleaning liquid generating device 1 is stored in the tank 15 and is sprayed onto the object to be cleaned by, for example, a liquid spraying device including a pump, an injection nozzle, or the like. The object to be sprayed with the cleaning liquid generated by the cleaning liquid generating device 1 is not particularly limited. Specific examples of such objects include bodies of various moving objects such as vehicles, ships, and aircraft, outer walls of structures such as buildings, walls exposed to the outside air, and various structures such as various electric appliances installed outdoors. Examples thereof include a surface portion of equipment, glass, a window provided with a transparent portion made of transparent resin, and the like. Further, the cleaning liquid generated by the cleaning liquid generating device 1 can also be used as a cleaning liquid for cleaning windows provided by various moving objects such as vehicles, ships, and aircraft, that is, a window washer liquid.

As described in detail above, the cleaning liquid generator can impart a cleaning function to a liquid such as water without using a detergent or the like. Further, when a cleaning liquid such as a surfactant is used as the source liquid of the generated cleaning liquid, a more excellent cleaning effect can be exhibited. Further, since the tubular flow path 5a of the liquid reforming unit 5 has a long cylindrical shape, it passes through the tubular flow path 5a as compared with the case where it is generated in a container such as a tank that is stored and used. The liquid reforming effect on the liquid (the liquid that is the source of the generated cleaning liquid) becomes large. That is, since the tubular flow path 5a is composed of the tubular flow path, the space efficiency is higher than the case where the tubular flow path 5a is composed of a container such as a tank, and the liquid reforming unit 5 passes through the liquid reforming unit 5 per unit time. The liquid becomes continuous, and as a result, efficient liquid reforming can be performed even with a small amount of liquid.

[Second Embodiment of Cleaning Liquid Generator]
FIG. 2 shows a schematic configuration of a cleaning liquid generator according to a second embodiment. Since the basic configuration of the second embodiment is substantially the same as that of the first embodiment, the description of the overlapping portion is omitted and incorporated, and the following description is different from that of the first embodiment. Only the part will be explained. The cleaning liquid generator 1 according to the second embodiment is provided with three first electrode portions 11 that function as anodes (+ poles) and are arranged in parallel with each other. Further, a second electrode portion 12 (hereinafter referred to as "electrode portion 12") that faces the first electrode portion 11 (hereinafter referred to as "electrode portion 11") and functions as a cathode (-pole). Are fixedly arranged in parallel with each other and facing the electrode portion 11.

The three electrode portions 11 that function as anodes (+ poles) are each electrically connected to the positive electrode (+ pole) of the power supply 7 via a cable. Further, each of the three electrode portions 12 that function as the cathode (-pole) is electrically connected to the negative electrode (-pole) of the power supply 7 via a cable. As described above, the number of each electrode portion is not limited to one as illustrated in FIG. 1, and may be a plurality of electrodes as illustrated in FIG. The cleaning liquid generating device according to the second embodiment is the same as the cleaning liquid generating device 1 of the first embodiment, except that the number of the electrode portions 11 and 12 is a plurality of arrangements. Since the cleaning liquid generator 1 of the second embodiment has a large number of electrodes, the efficiency of generating electrolyzed water is higher than that of the first embodiment.

[Third Embodiment of the cleaning liquid generator]
FIG. 3 shows a schematic configuration of a cleaning liquid generator according to a third embodiment. Since the basic configuration of the third embodiment is substantially the same as that of the first embodiment, the description thereof will be omitted, and the following description will explain only the parts different from those of the first embodiment. The cleaning liquid generating device 1 according to the third embodiment includes a polarity switching device 6 (polarity switching means) for switching (reversing) the polarities of the electrode portion 11 and the electrode portion 12. The electrode portions 11 and 12 are electrically connected to the power supply 7 via the polarity switch 6. The polarity switch 6 is configured to automatically and repeatedly switch the polarities of the electrode portion 11 and the electrode portion 12 at a predetermined timing (time set by a timer in advance). That is, each time a predetermined time elapses, the polarities of the electrode portion 11 and the electrode portion 12 can be automatically and repeatedly switched by using the polarity switch 6.

The electrode portion 11 and the electrode portion 12 always have opposite polarities. That is, when the electrode portion 11 functions as an anode (+ pole), the electrode portion 12 functions as a cathode (-pole), and conversely, when the electrode portion 11 functions as a cathode (-pole), the electrode portion 12 functions. Functions as an anode (+ electrode). For example, when the timing of several minutes, several hours, or several days is set as the above-mentioned set time, the electrode that has been functioning as an anode (+ electrode) until the set timing is reached. The part now functions as a cathode (-pole), and at the same time, the electrode part that has previously functioned as a cathode (-pole) now functions as an anode (+ pole). That is, the electrode portion 11 alternately functions as an anode (+ pole) and a cathode (-pole), and the electrode portion 12 alternately functions as a cathode (-pole) and an anode (+ pole). Become.

By providing the cleaning liquid generator 1 with such a polarity switch 6, dirt on the liquid reforming section 5 and dirt on the electrodes 11 and 12 are suppressed, and dirt adhering to the tubular flow path 5a is suppressed. Can also be dropped. In order to remove the removed dirt, it is preferable to provide the cleaning liquid generator 1 with a filter 19 for removing the dirt discharged from the tubular flow path 5a as shown in FIG. This makes it possible to prevent foreign matter from being mixed into the generated cleaning liquid. The polarity switching by the polarity switch 6 may be automatic as described above, or the polarity may be manually switched at an arbitrary timing.

[First Embodiment of Cleaning / Coating Liquid Generation Device 2]
The cleaning liquid generating device 1 according to the first to third embodiments described above is for generating a cleaning liquid for the outer surface of a structure, a painted surface of a moving body such as an automobile or a train, and the like. The cleaning / coating liquid generation device 2 according to the first embodiment shown in FIG. 4 has both functions of cleaning and coating the cleaned surface thereof. Since the basic configuration of the cleaning / coating liquid generating apparatus 2 according to the first embodiment is substantially the same as that of the first embodiment, the description thereof will be omitted, and the following description will be described in the first embodiment. Only the parts that differ from the above will be explained.

The coating composition generator 8 is connected to the flow path 32 connected to the discharge port of the pump 17 of the cleaning / coating liquid generator 2. In the coating composition generator 8, as will be described later, the ceramic complex 88 is housed in the tubular body (see FIG. 6), and the coating component is leached from the ceramic complex 88 into the cleaning liquid (Patent Document). 1). The cleaning / coating liquid generating device 2 of the first embodiment pressurizes and pumps a liquid (for example, public tap water) that is a source of the cleaning / coating liquid by a pump 17. The liquid pumped through the inside of the tubular body (cylinder) of the coating composition generator 8 passes through the inside of the tubular flow path 5a via the flow paths 32 and 33. It passes through, and further passes through the coating composition generator 8 and the tubular flow path 5a repeatedly via the flow paths 34, 35, the tank 15, and the like.

When the liquid is pumped in this way and the liquid is repeatedly circulated through the paths 31 to 35, the liquid repeatedly passes through the inside of the coating composition generator 8 and the inside of the tubular flow path 5a, and in the process, The original liquid (for example, tap water) changes to a cleaning / coating liquid. That is, a liquid having both cleaning and coating functions is produced. By repeatedly flowing the liquid (for example, tap water) that is the source of the cleaning / coating liquid into the inside of the tubular flow path 5a, the liquid has a cleaning function. Further, when the liquid (for example, tap water) that is the source of the cleaning / coating liquid repeatedly passes through the coating composition generator 8 (cylinder device), the liquid is transferred to the coating composition generator 8 (cylinder device) in the process. Repeated exposure to the coating composition inside leads to the original liquid, such as tap water, having a coating function.

Therefore, by repeatedly flowing the original liquid such as tap water into the coating composition generator 8 and the tubular flow path 5a, a "cleaning / coating liquid" having both a cleaning function and a coating function is generated. In the present embodiment, as shown in FIG. 4, the coating composition generator 8 is arranged on the upstream side and the tubular flow path 5a is arranged on the downstream side. The flow path 5a may be arranged on the upstream side, the coating composition generator 8 may be arranged on the downstream side, and both may be connected by the connecting flow paths 34 to 35. The cleaning / coating liquid generated by the cleaning / coating liquid generating device 2 is stored in the tank 15, and is used for cleaning objects such as the body of a vehicle and the outer wall of a building by a liquid spraying device including, for example, a pump and an injection nozzle. It is sprayed against.

The objects to be sprayed with the cleaning / coating liquid are not particularly limited, and specific examples thereof include bodies of various moving objects such as vehicles, ships, and aircraft, outer walls of permanent structures such as buildings, and walls exposed to the outside air. Examples thereof include various structures such as various electric appliances installed outdoors, surface parts of equipment, windows provided with transparent parts made of glass or transparent resin, and the like. Further, the cleaning / coating liquid generated by the cleaning / coating liquid generator 2 has a cleaning / coating liquid for cleaning windows of various moving objects such as vehicles, ships, and aircraft, that is, a coating function. It can also be used as a window washer fluid. In the cleaning / coating liquid generating apparatus of the present embodiment, when only the cleaning liquid is generated, a manual switching valve 23 is connected to the outlet of the pump 17, and when the liquid flows through the bypass flow path 32a, the circulating water becomes circulated. Since it does not pass through the coating composition generator 8, a cleaning liquid is generated.

[Modification example of tubular flow path 5a]
FIG. 5 is a cross-sectional view showing a modified example of the tubular flow path 5a. The central axis of the tubular flow path 5a according to the first to third embodiments is linear, but the shape is not limited to this shape. The tubular flow path 5a of this modified example has a U-shaped shape as a whole, and the central axis is linear at both ends, and a C-shaped curved pipe 5b is connected to the middle portion. To be precise, the center line of the C-shaped curved tube 5b has a straight line in the middle, and both ends are bent at 90 degrees. Therefore, the center line of the tubular flow path 5a on the liquid inlet 21 side and the center line of the tubular flow path 5a on the liquid outlet side are parallel. Therefore, the cleaning liquid generator according to the fourth embodiment has a compact structure. Further, there is an advantage that the distance between the first electrode portion 11 and the second electrode portion 12 can be long, and the tubular flow path 5a becomes compact. In the case of this example, the tubular flow path 5a and the middle curved pipe 5b are made of synthetic resin pipes having different diameters, but pipes of the same member may be molded. Further, in the portion of the curved pipe 5b, the center line of the central portion is a straight line, and both ends are bent at 90 degrees. Speaking from the center line of the tubular flow path 5a, since the central axis of the tubular flow path 5a of the first to third embodiments is a straight line, the central portion thereof is also a straight line, but this modification is a U-shape. It can be said that the shape is close to the shape. Although not shown, the central axis of the tubular flow path 5a may be circular, V, or C-shaped.

[Structure of coating composition generator provided in cleaning / coating liquid generator]
Next, a specific embodiment of the "coating composition generator 8" (see FIG. 4) constituting the cleaning / coating liquid generator 2 will be described with reference to FIGS. 6 and 7. The basic structure of this "coating composition generator 8" is a known technique (Japanese Patent Laid-Open No. 2011-518). The coating composition generator 8 is a cylinder type device that produces a slightly water-soluble silicon oxide solution. FIG. 6 is a schematic cross-sectional view showing the coating composition generator 8. in FIG. 6, the cylinder device 81 generates a so-called horizontal coating composition of a type that is arranged and used laterally. .. The cylinder 83 constituting this is a tubular body having both ends closed, and filters 86 and 87 are installed in the vicinity of both ends thereof, respectively.

A massive ceramic complex 88 is provided between these filters 86 and 87, and the ceramic complex 88 is preferably a granular material. The ceramic complex 88 corresponds to a “coating composition”. The amount of the ceramic complex 88, that is, the filling rate of the space in the cylinder 83 is arbitrary, but from the viewpoint of stirring efficiency, it is preferably 20% to 80%, more preferably 30% to 70%. The most preferable is around 50%. The filters 86 and 87 are preferably a mesh that does not pass through the particles of the ceramic complex 88. The basic plasticity of this ceramic complex 88 is a known technique (Patent No. 4,012,930).

The coating composition generator 8 has a liquid inlet 91 and a liquid outlet 92 at both ends, wherein the liquid inlet 91 is formed at one end of a liquid ejection pipe 82.

It extends to the vicinity. The liquid flowing out from the liquid outlet 92 flows into the liquid reforming unit 5 through the flow path 32. Further, the liquid ejection pipe 82 has a liquid inlet 91 and a closed tip as described above, and has one or more liquid ejection holes 85 on the side wall of the pipe. As shown in FIG. 7A, when the injection of the liquid ejection hole 85 is injected at an angle from the radial direction of the liquid ejection pipe 82, the ejected liquid swirls in the tubular body 83 and is made of a ceramic composite. The particles of body 88 are kept in a suspended state. By swirling the ceramic complex 88, the ceramic complex 88 is mixed and stirred, and the elution of the coating component is promoted.

When, for example, public tap water is introduced from the liquid inlet 91 of the liquid ejection pipe 82 in the coating composition generator 8, the tap water ejected from the liquid ejection hole 85 is swirled to satisfactorily suspend the particles of the ceramic composite 88. be able to. The particles of the ceramic composite 88 used in the present embodiment are made of a ceramic composite obtained by sintering a polymer initial condensate of silicon dioxide and an electric stone, which is dispersed in tap water to give a mechanical stimulus. And silicon oxide is eluted to obtain a slightly water-soluble silicon oxide solution. Further, by repeatedly flowing this slightly water-soluble silicon oxide solution through the coating composition generator 8, a concentrated slightly water-soluble silicon oxide solution is obtained.

As shown in FIG. 8A, first, an outer panel used for an automobile or the like made of FRP was prepared, which was painted with a general white paint. The size of this white plate is 50 cm in length and 100 cm in width. The white plate was equally divided into two regions on the left and right by a boundary line (intermediate line) arranged in the middle. The left surface was used as the experimental area of Example 1 (area for cleaning with cleaning liquid), and the right surface was used as the experimental area for comparative examples (area for cleaning with public tap water).

Next, as shown in FIG. 8B, cooking salad oil colored with a brush was applied to the entire surface of the white plate.

The results are shown in Table 1 below.

That is, it was confirmed that the cleaning liquid generator of the present invention can give a liquid such as water an excellent cleaning function without using a detergent or the like. From the results of this experiment, when a liquid containing a detergent is used as the liquid that is the source of the cleaning liquid to be produced, the liquid containing the detergent can exert a more excellent cleaning effect.

An experiment was conducted in which a cleaning / coating liquid was generated using a cleaning / coating liquid generator, and both the cleaning effect and the coating effect of the cleaning / coating liquid were confirmed. The cleaning / coating liquid generating apparatus used in the experiment has the same configuration as the apparatus of the first embodiment shown in FIG. The specific specifications of the apparatus and power supply used in the experiment are the same as those in the first embodiment. A cleaning / coating liquid generator and power supply with the above specifications were prepared. Then, "public tap water" was prepared as the source liquid of the cleaning / coating liquid to be generated, and the cleaning / coating liquid was generated using the cleaning / coating liquid generating device described above. In this generation, the switch of the power supply 7 is turned on while the liquid is flowing inside the tubular flow path 5a, and the liquid in which the two electrode portions 11 and the electrode portions 12 are in contact (cylindrical flow path 5a). A voltage was applied to the liquid flowing inside the. The cleaning / coating liquid thus produced was designated as Example 2. Further, tap water (untreated tap water to which no voltage was applied) was used as Comparative Example 2. The experimental conditions of the washing water generator are the same as in Example 1.

[Flow of experiment to confirm cleaning effect]

The flow of the coating effect confirmation experiment using the cleaning liquid (Example 2) and tap water (Comparative Example 2) is roughly as shown in FIG. As shown in FIG. 9A, a white plate similar to that in Example 1 was prepared. Next, as shown in FIG. 9B, a cleaning / coating liquid was applied to the experimental area for the example on the left side of the white plate using a brush to form a coating derived from the liquid. In addition, tap water was simply applied to the experimental area on the right side of the white plate for comparative examples. Then, it waited until each of the applied liquids dried.

Next, as shown in FIG. 9C, edible salad oil was applied to the entire surface of the white plate using a brush. As a result, an oil film was uniformly formed on the entire surface of the white plate. In the experiment, this oil film was treated as oil stain. Next, as shown in FIG. 9D, tap water was sprayed on both the experimental area of the example and the experimental area of the comparative example using a spray to wash away the oil-stained left and right areas with tap water. .. At that time, the amount of tap water used to wash away oil stains was equalized so that there would be no difference between the left and right regions.

Next, the degree of oil stain (oil film) removed by tap water in the example region and the degree of oil stain (oil film) removed by tap water in the comparative example region were visually observed.

The results are shown in Table 2 below.

That is, it was confirmed that the cleaning / coating liquid generating apparatus of the present invention can generate a liquid having both a cleaning function and a coating function, which is neither a mere cleaning liquid nor a mere coating liquid. It was also confirmed that a liquid such as water can have a cleaning function and a coating function without using a detergent or the like. When a cleaning liquid is used as the source liquid of the generated cleaning / coating liquid, the cleaning liquid can exert a more excellent cleaning effect, and can also have a coating function.

An experiment was conducted in which a cleaning liquid was generated using a cleaning liquid generator equipped with a polarity switching unit, and the effect of suppressing stains on the liquid reforming unit was confirmed. The cleaning liquid generating device used in the experiment had the same configuration as the device of the third embodiment shown in FIG. The specific specifications of the cleaning liquid generator (cylindrical flow path) and power supply used in the experiment are the same as those of Example 1 described above. "Tap water" was prepared as the source liquid of the cleaning liquid to be generated, and the cleaning liquid was generated using the cleaning liquid generating device of the above specifications (the device of the third embodiment). At that time, with the liquid flowing inside the tubular flow path 5a, the switch of the power supply 7 is turned on, and the liquid in which the two electrode portions 11 and 12 are in contact (the inside of the liquid reforming portion 5). A voltage was applied to the flowing liquid).

Further, the circulation of the liquid and the application of the voltage in the cleaning liquid generating device (the device of the third embodiment) were continuously performed for 30 days. That is, the same liquid was continuously circulated for 30 days while the voltage was applied by the electrodes 11 and 12. Further, in the process of liquid circulation (cleaning liquid generation) for 30 days, the polarities of the first electrode portion 11 and the second electrode portion 12 were simultaneously switched at the frequency shown in Table 3. The polarity was switched simultaneously and automatically. After circulating the same liquid continuously for 30 days, the degree of contamination inside the liquid reforming unit 5 was confirmed. The results are shown in Table 3 below.

That is, it was confirmed that by repeatedly switching the polarities of the first electrode portion 11 and the second electrode portion 12 by the polarity switcher 6, dirt on the liquid reforming portion 5 in the cleaning liquid generator 1 can be suppressed.
