Description

  TECHNICAL FIELD The present invention relates to a stain removal cleaning machine and a stain removal cleaning method capable of cleaning dirt due to particles such as mud dirt and stain due to dye at the same time and pinpoint.

  Particles such as mud stains or stains such as dyes may be attached to pinpoints on clothes or the like. In the present specification, these stains are collectively referred to as “spots”, and removing these stains is also referred to as “spot removal” in the present specification. As a method for cleaning and removing the dirt attached to the object to be cleaned in a pinpoint manner, ultrasonic waves in a state in which the object to be cleaned as described in Patent Document 1 or Patent Document 2 is impregnated with water or a cleaning liquid are used. There is a device that contacts a vibrator and repels dirt by ultrasonic vibration, and it has been actually used.

  However, in the cleaning method using ultrasonic vibration, dirt adhering between the fibers of the object to be cleaned is blown away to clean and remove dirt.Therefore, stains due to dyes, such as black spots on black tea, can be removed. could not. If the object to be cleaned is dipped in a detergent during the cleaning by the ultrasonic vibration, stains due to the dye can be removed to some extent, but it was not sufficient.

  Regarding the enhancement of detergency, Patent Document 3 electrolyzes salt water stored in an outer tub to generate bleaching water containing hypochlorite ions, and bleaching laundry with this bleaching water to remove stains. It describes a washing machine to remove. Hypochlorite ion is used as a bleaching agent because it has a high oxidizing power. The stains due to the dye are oxidized by the oxidizing power of the hypochlorous acid, and the stains can be removed by bleaching. Hypochlorite ion is obtained by electrolyzing a solution of a salt containing chloride ion. However, bleaching with hypochlorite ion can wash and remove stains due to dyes, but cannot remove stains due to particles. Further, Patent Document 3 relates to a washing machine that rotationally drives the inner tub, and is not a device that can be easily carried and stain-removed, and not a device that can remove stains pinpoint.

  In Patent Document 4, a material to be cleaned is sandwiched between a pair of electrodes in a state of being impregnated with water or a cleaning solution, and a voltage is applied to the electrodes to electrolyze the water or the cleaning solution and remove spots at pinpoint points. Vessels are shown. However, the stain removal of the object to be cleaned is limited to the portion which can be sandwiched by the pair of electrodes of the stain remover. Further, if the pair of electrodes is magnetically sandwiched, the work becomes complicated. Furthermore, since dirt such as mud dirt cannot be removed by particles, a separate dirt removing operation is required.

It is a typical sectional view of one embodiment of the stain removal cleaning machine of the present invention. It is an expanded sectional view of the washing | cleaning part of the spot removal washing machine of FIG.

Hereinafter, embodiments of the stain removing and cleaning machine of the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows a schematic cross-sectional view of one embodiment of the stain remover / cleaner of the present invention. As shown in FIG. 1, a stain remover / cleaner 1 according to the present embodiment is provided with a main body 2 having a substantially cylindrical shape with a size that can be held by a human hand, and one end of the main body 2. The cleaning unit 3 is provided. As shown in the enlarged cross-sectional view of FIG. 2, the cleaning unit 3 has a substantially truncated cone shape, and the tip of the ultrasonic transducer 4 vibratably projects from the opening of the portion corresponding to the upper bottom thereof. , A pair of electrodes 7 composed of the anode 5 and the cathode 6 are projected.

In the illustrated example, the anode 5 and the cathode 6 have a flat plate shape, and are provided so as to sandwich the ultrasonic transducer 4 protruding from the center of the substantially truncated cone shape. The anode 5 and the cathode 6 are made of an electrically conductive material, and for example, copper, stainless steel, or titanium can be used in consideration of corrosion resistance. In addition, an appropriate coating such as platinum plating can be formed on these metal materials, if necessary. The anode 5 and the cathode 6 are separated by an interval capable of electrolyzing inorganic chloride in the cleaning liquid, for example, 10 mm or less.
In order to protect the ultrasonic transducer 4 and the electrode 7 protruding from the tip, the cleaning unit 3 may be provided with a cap (not shown) if necessary.

  The ultrasonic oscillator 4 has, for example, a horn shape or a cone shape, and its tip has a shape suitable for cleaning by ultrasonic vibration. In order to vibrate the ultrasonic oscillator 4, a piezoelectric element 4a is integrally attached to the ultrasonic oscillator 4. The piezoelectric element 4a may be a known piezoelectric element such as lead zirconate titanate (PZT).

  In the internal space of the outer casing 8 which gives the outer shape of the main body portion 2, an oscillator circuit portion 9 for the ultrasonic oscillator 4, a switch 10 for operating the ultrasonic oscillator 4, and a switch for energizing the electrodes. The switch 11 is housed. Further, in the stain removing / cleaning machine 1 of the present embodiment shown in FIG. 1, a dry battery 12 as a power source is housed in the internal space of the exterior 8.

  The dry battery 12 as a power source can supply a predetermined voltage between the anode 5 and the cathode 6 of the electrode 7, more specifically, a voltage capable of electrolyzing the inorganic chloride in the cleaning liquid, and ultrasonic vibration. It is possible to supply a voltage for driving the child 4. Specifically, it may be 2 V or more, and a voltage of about 3 to 5 V may be sufficient. It should be noted that the provision of a transformer circuit between the dry battery 12 as a power source and the electrode 7 or the ultrasonic transducer 4 in the main body does not prevent the transformer circuit from being provided.

  The stain removing and cleaning machine 1 of the present embodiment includes an ultrasonic vibrator 4 for generating ultrasonic vibrations in the cleaning unit 3 and an oxidizer for electrolyzing a cleaning liquid, specifically, hypochlorite ions or the like. A pair of electrodes 7 composed of an anode 5 and a cathode 6 for generating at least one kind of chloride ion, and the tip of the ultrasonic transducer 4 and the tips of the anode 5 and the cathode 6 are to be cleaned. By pressing against the cleaning area C1 of the object C, dirt due to particles such as mud dirt adhering to the surface C1 to be cleaned of the object C is ultrasonically vibrated, and dirt due to the dye is simultaneously and pinpointed by electrolysis. Can be washed. That is, the particles attached between the fibers of the object to be cleaned are repelled by the vibration of the ultrasonic transducer 4 to clean and remove the dirt, and the dirt is contained in the cleaning liquid impregnated in the area C1 to be cleaned of the object C to be cleaned. Inorganic chloride generated is electrolyzed at the anode 5 and the cathode 6 to generate at least one kind of chloride ion such as hypochlorite ion, and the bleaching power of the chloride ion is used to change the dye to be washed. Clean the dirt.

  Then, when the range of the stain is the pinpoint, it remains as it is, and when the range of the stain extends to a predetermined region, the stain removing and cleaning machine 1 is manually moved to ultrasonically vibrate on the surface of the region to be cleaned C1. By moving the child 4 and the electrode 7, the predetermined area where the stain is generated is washed.

  As a technique for removing dirt adhering to items to be washed such as clothes, there is a method of blowing off particles between fibers with an ultrasonic vibrator, and a method using the bleaching power of hypochlorite ion is available. There are stains that can be removed / washed and stains that cannot be washed by either method. This is because there are two types of stains on clothes and the like, which are stains due to particles such as mud stains adhering between fibers and stains due to dyes such as stains on black tea. Ultrasonic cleaning is suitable for stains caused by such particles, and bleaching with hypochlorite ions is suitable for stains caused by dyes.

  Therefore, the stain removing and cleaning machine 1 of the present embodiment can perform ultrasonic cleaning by vibrating the ultrasonic vibrator 4, and by electrolyzing the inorganic chloride in the cleaning liquid with the electrode 7, Bleaching can be performed with at least one chloride ion such as chlorate ion. Then, by simultaneously operating the ultrasonic transducer 4 and the electrode 7, it is possible to wash even a composite stain of mud stain and the stain due to the dye at once. It is not limited to the case of operating at the same time, and either one can be operated.

Next, a modified example of the stain remover / cleaner 1 of the present embodiment will be described.
As the anode 5 and the cathode 6 of the electrode 7, the anode 5 shown in FIG. 1 may be used as the cathode and the cathode 6 may be used as the anode. In any case, the electrode 7 is supplied with power from a DC power supply. The shapes of the anode 5 and the cathode 6 are not limited to the flat plate shape shown in FIG. Since the area where the anode 5 and the cathode 6 are in contact with the region C1 to be cleaned of the object to be cleaned C is the electrolytic area, it is possible to change the range where stain removal is possible by changing this electrolytic area. For example, by making the anode 5 and the cathode 6 into a rod shape having a small diameter, it is possible to remove spots on the object to be cleaned C more pinpointly than in the flat plate shape. The anode 5 and the cathode 6 are arranged to face each other, and during the electrolysis, the anode 5 and the cathode 6 need to be in contact with the object to be cleaned impregnated with water or a cleaning liquid.

  The ultrasonic oscillator 4 and the electrode 7 for electrolysis can operate one or both of the ultrasonic oscillator 4 and the electrode 7 at the same time by operating the switches 10 and 11. This makes it possible to remove stains caused by both particles and dyes without performing a plurality of procedures such as ultrasonic vibration and then electrolysis.

  In addition, it is possible to appropriately control the stain removal by properly using only one of ultrasonic vibration or electrolysis depending on the stain component. For example, when the object to be cleaned is soiled only with mud, by applying only the ultrasonic vibration by the ultrasonic oscillator 4 to the object to be cleaned, the contamination can be removed with lower power. In the example shown in FIG. 1, the on / off switch 10 for the ultrasonic transducer 4 and the on / off switch 11 for the electrode 7 are shown, but the function of the switch 10 and the function of the switch 11 are combined into one. A changeover switch can also be used.

  Further, the stain remover / cleaner 1 is cordless in the example shown in FIG. 1, and is supplied with electric power from the dry battery 12, but a rechargeable secondary battery may be used instead of the dry battery 12. It is also conceivable that the main body 2 does not have a power source, and power is supplied from the outside by a wired power cord or wirelessly. However, in the stain remover / cleaner 1 of the present embodiment, the dry battery 12 and the rechargeable secondary battery are housed in the main body 2 so as to be cordless, so that the power cord is not required and the handling at the time of cleaning becomes easier. ing.

Next, the water or the cleaning liquid used when removing stains using the stain remover / cleaner 1 will be described.
The object to be cleaned C is preferably impregnated with water or a cleaning liquid. In particular, when bleaching by electrolysis is performed by the electrode 7, it is necessary to impregnate the cleaning liquid. When impregnated with water, chloride ions such as hypochlorite ions are not generated even if the electrode 7 is energized, but it is easy to remove stains by ultrasonic vibration.

  The cleaning liquid preferably contains water, (a) one or more kinds of inorganic chlorides that ionically dissociate in the cleaning liquid to generate chloride ions, and (b) one or more kinds of surfactants. By the chloride ion generated when this inorganic chloride is ionized in water, hypochlorite ion having a bleaching ability can be generated during electrolysis. Inorganic chlorides that generate chloride ions in the cleaning liquid include, for example, sodium chloride, calcium chloride, potassium chloride, and one or more of these can be used. The concentration of such inorganic chloride in the cleaning liquid is preferably about 0.1 to 20%.

  If the cleaning liquid does not contain inorganic chloride that produces chloride ions, generally hypochlorite ions with bleaching ability are not generated, but it is possible to remove stains by the action of a surfactant. It may be included as a cleaning liquid used at the time of cleaning using the stain remover of the invention.

  Further, the surfactant includes a surfactant containing chlorine. Chlorine-containing surfactants release chlorine ions in solution and can be bleached. Thus, the cleaning liquid can contain a chlorine-containing surfactant, with or without an inorganic chloride agent. A trade name manufactured by Kao Corporation: Coatamine 86W (stearyltrimethylammonium chloride) can be mentioned.

  In addition, the cleaning liquid preferably contains a surfactant that can coexist with chloride ions such as hypochlorite ions generated during electrolysis. Examples of the surfactant that can coexist with chloride ions include polyoxyalkylene alkyl ether sulfate ester salts, polyoxyethylene alkyl ethers, fatty acid salts, polyoxyalkylene alkyl ethers, and alkyl ammonium salts.

In addition to the above-mentioned surfactants, one or more of an amphoteric surfactant, an anionic surfactant and a nonionic surfactant can be contained.
Examples of the amphoteric surfactant include betaine such as alkyldimethylamino fatty acid betaine and amine oxide such as alkyldimethylamine oxide.

  Examples of the anionic surfactant include higher alcohol sulfonates, higher fatty acid salts, higher alcohol sulfate ester salts, sulfated fatty acid salts, phosphorylated ester salts, sulfonated fatty acid salts, sulfate ester salts of fatty acid esters or sulfonate ester salts. , Sulfates or sulfonates of higher alcohol ethers, condensates of amino acids and fatty acids, alkylol sulfates or alkylated sulfonates of fatty acid amides, ether carboxylic acids or salts thereof, amide ether carboxylic acids or their Examples thereof include salts, sulfosuccinic acid ester salts, alkylphenol sulfonates, alkylbenzene sulfonates, alkylbenzimidazole sulfonates, and alkylnaphthalenesulfonates.

  Examples of the nonionic surfactant include polyoxyethylene alkyl ether, alkyl polyglycoside, alkyl polyglycol ether, glucamide, amine oxide, sucrose fatty acid ester, alkenyl ether, alkylamine oxide, and fatty acid alkanolamide.

  The total concentration of such a surfactant in the cleaning liquid is preferably about 0.1 to 10%.

Furthermore, it is more preferable that the cleaning liquid contains one or more preservatives selected from ethanol, paraben and the like. The concentration of such a preservative in the cleaning liquid is preferably about 0.01 to 3.0%.
Further, as the pH adjuster, one or more kinds of acids such as sulfuric acid, hydrochloric acid and acetic acid can be contained. Hypochlorite ion as chloride ion changes its form depending on the pH of the aqueous solution, and exists as non-dissociated hypochlorous acid under acidic conditions. Undissociated hypochlorous acid has a higher bleaching power than hypochlorite ions. Non-dissociated hypochlorous acid is obtained by adjusting the pH in an aqueous solution. Therefore, by adding the above-mentioned pH adjuster, electrolytic hypochlorous acid water is generated when electrolysis is performed, and higher cleaning / bleaching ability can be exhibited for the object to be cleaned.
When such a pH adjusting agent is added, a cationic surfactant can be further added. Examples of the cationic surfactant include a primary amine salt, a secondary amine salt, a tertiary amine salt, a quaternary ammonium salt and the like, and of these, a quaternary ammonium salt is particularly preferable.
In addition, the cleaning agent may include a fragrance or the like.

  The cleaning liquid may be a liquid before use, or may be a powder that is dissolved in water before use. It may also be in the form of gel. By using the gel-like cleaning liquid having a high viscosity, it is possible to suppress the diffusion of the object to be cleaned from the cleaning portion and to impregnate the cleaning liquid only in the cleaning portion, and to suppress the bleaching of the cleaning portion.

  At the time of cleaning, a stain may be removed by disposing a patch cloth on the back of the object C to be cleaned impregnated with water or a cleaning liquid. When cleaning is performed, the water or cleaning liquid impregnated in the cleaning target C contains stain components. Therefore, by putting a patch cloth on the back of the cleaning target, the contaminated water or cleaning liquid is applied from the cleaning target. It is possible to prevent the contaminated water or the cleaning liquid that is absorbed by the above from contaminating the object to be cleaned other than the cleaning target portion.

Next, a stain removal cleaning method using the stain removal cleaning machine 1 will be described below.
After the cleaning area C1 of the cleaning object C is impregnated with water or cleaning liquid, the stain removing cleaning machine 1 is held with one hand, and the tip of the cleaning section 3 constituted by the ultrasonic transducer 4 and the electrode 7 is moved downward. The cleaning target area C1 against the cleaning target area C1.

When the ultrasonic oscillator 4 is driven in this state, the ultrasonic vibration by the ultrasonic oscillator 4 propagates to the object to be cleaned C through water or the cleaning liquid, and the dirt derived from particles attached to the object to be cleaned C is removed. To be done.
Further, when power is supplied to the electrode 7, the cleaning liquid impregnated with the object to be cleaned C is electrolyzed, and the chloride ions such as hypochlorite ions generated remove stains derived from the dye on the object to be cleaned C. It

Further, by simultaneously operating both the ultrasonic transducer 4 and the electrode 7, it is possible to easily remove stains originating from both particles and dyes without performing a plurality of steps.
The cleaning can be performed while spraying water or a cleaning liquid on the cleaning unit. As a result, the dirty cleaning liquid after cleaning can be quickly removed, and the redeposition of dirt can be prevented.
Further, during the cleaning, the cleaning can be performed while spraying water or the cleaning liquid on the cleaning portion and at the same time while suctioning the water or the cleaning liquid. As a result, the dirty cleaning liquid after cleaning can be quickly removed, and the redeposition of dirt can be prevented.
After the stain stain removal, the water or the cleaning liquid impregnated with the object to be cleaned C contains the electrolytic product such as hypochlorite ion and the stain component, and therefore the object to be cleaned C is washed away with running water.
In this way, by using the stain removing / cleaning machine 1 according to the present invention, various stain stains adhering to the object to be cleaned can be easily removed by one-handed operation.

(Example 1)
Using the stain removing and cleaning machine of the present invention, in order to clarify the effect of removing mud stains and stains, mud-contaminated cloth of white cotton cloth soiled with red soil, which is one of particle stains, and one of natural dyes. 2 shows the results of measuring the bleaching performance of three types of soiled cotton fabrics, that is, a black soiled cotton fabric soiled with black tea and a soiled cotton fabric soiled with both mud particles and dye.

The mud-contaminated cloth used in the bleaching experiment was prepared by the following method. A white cloth (gold cloth # 2003) made of 100% cotton was dipped in a 13.0% by mass red soil solution to make dirt adhere, and brushing contamination was performed by rubbing mud. After the cloth was thoroughly dried, the excess mud was cut off and cut into pieces of about 5 × 5 cm ² . The reflectance of the contaminated cloth cut with a spectroscopic color difference meter (Nippon Denshoku NF333) was measured, and a contaminated cloth having a difference from the average reflectance of 1% or less was used as a test piece.

The black tea-contaminated cloth used in the bleaching experiment was prepared by the following method. Seven commercially available black teas (Nitto black tea yellow package) were boiled in 1 L of ion-exchanged water for 10 minutes and filtered with bleached cotton that had been punched to obtain a black tea liquid. White cloth was dipped in this solution and boiled for 5 minutes. After that, the color of black tea was fixed on a white cloth by removing it from the fire and leaving it for a whole day and night. The cloth was taken out from the black tea liquid, air-dried, and washed with tap water until the cleaning liquid was no longer colored, and then smooth-dried with an iron and cut into about 5 × 5 cm ² . The reflectance of the contaminated cloth cut with a spectroscopic color difference meter (Nippon Denshoku NF333) was measured, and a contaminated cloth having a difference from the average reflectance of 1% or less was used as a test piece.

The black and black soiled cloth used in the bleaching experiment was prepared by the following method. The black tea-contaminated cloth prepared as described above was immersed in 13.0% by mass of red pearl soil contaminated liquid to attach dirt, and brushing contamination was performed by rubbing mud. After the cloth was thoroughly dried, the excess mud was cut off and cut into pieces of about 5 × 5 cm ² . The reflectance of the contaminated cloth cut with a spectroscopic color difference meter (Nippon Denshoku NF333) was measured, and a contaminated cloth having a difference from the average reflectance of 1% or less was used as a test piece.

A cleaning solution was immersed in each contaminated cloth, and the cloth was washed using the stain removing cleaner shown in FIG. 1 to examine the bleaching performance.
The stain removing and cleaning machine used for cleaning is provided with a piezoelectric body of 50 kHz as an ultrasonic vibrator and can output 6 W. The two electrodes are set so that a direct current of 0.5 A flows with 10 mass% saline.

  The cleaning solution used for cleaning was a solution of commercially available Kao Co., Ltd. clothing detergent (trade name: Attack Antibacterial EX Super Clear Gel) diluted about 200 times with tap water, and 10% by mass of salt added to the solution. Using. This clothing detergent contains a polyoxyethylene alkyl ether, a polyoxyalkylene alkyl ether, a fatty acid salt, and an alkyl ammonium salt as a surfactant.

  For cleaning, the ultrasonic vibration of the stain removing and cleaning machine shown in FIG. 1 and a power source for electrolysis were turned on at the same time, and first, the tea-contaminated cloth was bleached. The cleaning liquid was constantly supplied so that the cloth was sufficiently wet. The processing time was 3 minutes. Then, using the same washing solution, a bleaching experiment for a cloth contaminated with mud was also conducted for 3 minutes. Then, using the same washing solution, a bleaching experiment was conducted on black and black soiled cloths for 3 minutes.

なお、白布とは、汚染布を作製した元の綿１００％の白布である。
（上記汚染布の作製方法および洗浄効果の測定方法に関する参考文献は、北折典之、勝村元美、Material Technology, Vol.31,No.2,31-38(2013)） The bleaching performance was measured by drying each sample cloth after washing, measuring the surface reflectance, and determining the bleaching rate from the reflectance. The reflectance was measured with a spectral color difference meter (Nippon Denshoku NF333).
The following equation was used to obtain the bleaching rate from the measured reflectance.

In addition, the white cloth is a white cloth made of 100% cotton, which is the original material for the contaminated cloth.
(References on the method for producing the contaminated cloth and the method for measuring the cleaning effect are Noriyuki Kitaori, Motomi Katsumura, Material Technology, Vol.31, No.2, 31-38 (2013))

  The results are summarized in Table 1. From Table 1, the bleaching rate of all three types of cloth contaminated with mud, cloth contaminated with black tea, and cloth contaminated with black tea and mud exceeded 80%, and it was possible to bleach particle stains due to mud and stains due to dye.

表中、ＵＳは超音波洗浄、Ｅは電気分解を示し、ＵＳ＋Ｅは超音波洗浄と電気分解とを同時に行ったことを示す。また、表中の数字は漂白率（％）であり、数値が高いほど漂白力が高いことを示す。

In the table, US indicates ultrasonic cleaning, E indicates electrolysis, and US + E indicates that ultrasonic cleaning and electrolysis were performed at the same time. The numbers in the table are bleaching rates (%), and the higher the number, the higher the bleaching power.

(Example 2)
The same experiment as in Example 1 was performed using a solution of potassium chloride (manufactured by Kanto Kagaku Co., Ltd.) dissolved in tap water in an amount of 10% by mass. The results are also shown in Table 1. All stains showed a bleaching rate of 80% or more.

(Example 3)
As in Example 1, the cleaning liquid used was a commercially available Kao clothing detergent Attack Antibacterial EX Super Clear Gel diluted about 200 times with tap water to which 10% by mass of salt was added, and at the time of cleaning. Cleaning was performed while tap water was sprayed on the tip of the device.
The results are shown in Table 1. From Table 1, the bleaching rate of all the stains was 80% or more, and the bleaching rate of the mud stain was very high.

(Example 4)
Cleaning was performed while sucking the dirty cleaning liquid in Example 3.
The results are shown in Table 1. From Table 1, the bleaching rate of all stains was 80% or more, and the bleaching rate was very high for mud stains and tea-contaminated cloth.

(Example 5)
In Example 1, an experiment was conducted by turning on only the ultrasonic wave and not applying a current to the electrolysis. (Cleaning only with ultrasonic waves)
The results are shown in Table 1. The bleaching rate of the mud-contaminated cloth was 81%, but the bleaching rate of the black-polluted cloth and the cloth contaminated with mud and black tea was low.

(Example 6)
In Example 1, an electric current was applied to the electrolysis, and an experiment was conducted without turning on the ultrasonic wave. (Cleaning only by electrolysis)
The results are shown in Table 1. The bleaching rate of the black tea-contaminated cloth was 88%, but the bleaching rate of the mud-contaminated cloth and the cloth contaminated with the mud and black tea was low.

It has been found that it is effective to simultaneously perform ultrasonic vibration and electrolysis using the stain removing and cleaning machine of the present invention in order to deal with any stain. Further, it may be considered that the structure in which the ultrasonic transducer is sandwiched between the electrodes is particularly effective. It is considered that this is because the hypochlorite ion generated by electrolysis is quickly permeated into the cotton fabric.
In addition, it was confirmed from the examples that spraying and suctioning of tap water further increases the effect of the present invention as a measure for quickly removing dirty cleaning liquid and preventing redeposition of dirt.

  Although the respective embodiments of the stain remover / cleaner of the present invention have been described above, the stain remover / cleaner of the present invention is not limited to these embodiments, and various embodiments are possible without departing from the spirit of the present invention. Deformation is possible.
