  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The cleaning device 40 according to the present embodiment includes the plasma generator 1 as shown in FIG. 1, and water containing ozone, hydroxy radicals, or the like generated by the plasma generator 1 is used as cleaning water. ing.

  The plasma generator 1 includes a substantially cylindrical case member 2. Note that the shape of the case member is not limited to a cylindrical shape, and may be, for example, a rectangular tube shape.

  As shown in FIG. 1, a ceramic member 3 is disposed inside the case member 2, and the internal space of the case member 2 is partitioned vertically by the ceramic member 3.

  In the present embodiment, the upper region of the ceramic member 3 in the internal space of the case member 2 is the liquid storage portion 4 that stores the liquid 17 (see FIGS. 3 and 4) containing water, and the lower side. The region is a gas containing portion 5 for containing gas.

  Thus, in this embodiment, the ceramic member 3 corresponds to a partition wall that separates the liquid container 4 and the gas container 5.

In addition, a gas introduction port 9 is provided below the side wall 2b of the case member 2 so as to communicate the gas storage portion 5 with the outside. A pipe (gas introduction path) 10 is inserted into the gas introduction port 9. ing. And the gas accommodating part 5 and the gas supply part 11 are connected via the piping 10. FIG. In the present embodiment, a gas containing at least oxygen (O ₂ ) is supplied from the gas supply unit 11 into the gas storage unit 5.

  Further, a gas passage 3a is formed in the ceramic member 3, and the gas or the like introduced from the gas supply unit 11 into the gas storage unit 5 is sent out into the liquid storage unit 4 through the gas passage 3a. Become.

  Thus, the gas supply part 11 concerning this embodiment supplies the gas which contains oxygen at least to the gas accommodating part 5 by the aspect which pumps the gas of the gas accommodating part 5 to the liquid accommodating part 4 via the gas channel | path 3a. It has a function to do.

  In the present embodiment, the hole diameter of the gas passage 3a is set to about 1 μm to 10 μm, and the liquid 17 stored in the liquid storage portion 4 does not leak into the gas storage portion 5 from the gas passage 3a. ing.

  In addition, the plasma generator 1 is separated from the first electrode 12 disposed in the gas storage unit 5 by a distance from the first electrode 12, and at least a portion on the side paired with the first electrode 12 (the first electrode 12). And a second electrode 13 disposed so that the surface of the liquid containing portion 4 is in contact with the liquid 17 in the liquid storage portion 4.

  Specifically, the doughnut-shaped first electrode 12 and the doughnut-shaped second electrode 13 are disposed in the gas storage unit 5 and the liquid storage unit 4, respectively.

  As shown in FIG. 1, the doughnut-shaped first electrode 12 is disposed on the surface 3 b of the ceramic member 3 on the gas accommodating portion 5 side so that the center is the gas passage 3 a. The surface of the first electrode 12 is covered with a dielectric (not shown).

  In addition, the second electrode 13 has at least a portion that is paired with the first electrode 12 (a surface that generates a discharge between the second electrode 13 and the surface of the first electrode 12) in contact with the liquid 17 in the liquid storage unit 4. Further, it is disposed in the liquid storage part 4. The second electrode 13 is disposed on the surface 3d of the ceramic member 3 on the liquid container 4 side so that the center is the gas passage 3a. That is, the first electrode 12 and the second electrode 13 are disposed concentrically on the surface of the ceramic member 3.

  As described above, in the plasma generator 1 according to this embodiment, the first electrode 12 is introduced into the liquid storage unit 4 by arranging the doughnut-shaped first electrode 12 in the gas storage unit 5. To avoid contact.

  On the other hand, by disposing the doughnut-shaped second electrode 13 in the liquid storage part 4, the second electrode 13 (including at least the part on the side paired with the first electrode 12) is introduced into the liquid storage part 4. In contact with the liquid 17.

  The first electrode 12 and the second electrode 13 are electrically connected to the plasma power supply unit 15 (see FIG. 1) via lead wires 14, and the first electrode 12 and the second electrode 13 are connected to each other. A predetermined voltage is applied between them. At this time, as shown in FIG. 2, it is preferable that the potential on the second electrode 13 side in the liquid 17 is lower than the potential on the first electrode 12 side in the gas. This is because the risk of electric shock can be avoided.

  Next, the operation of the above-described plasma generator 1 and the method for generating hydroxy radicals will be described.

  First, the gas containing oxygen is supplied to the gas accommodating part 5 in the aspect which pumps the gas of the gas accommodating part 5 to the liquid accommodating part 4 via the gas channel | path 3a (process to supply gas).

In the present embodiment, as shown in FIG. 1, a gas containing oxygen based on air (flow rate of about 0.01 L / min to 1.0 L / min (10 cc / min to 1000 cc / min)) is a gas supply unit. 11 is sent into the gas storage unit 5 through the pipe 10. At this time, the pressure for feeding the gas is set to about 0.0098 MPa to 0.49 MPa (0.1 kgf / cm ^{2 to 5} kgf / cm ² ).

  As described above, the gas supply unit 11 has a function of supplying gas (air) in the atmosphere. The gas supply flow rate is controlled by a flow rate control unit (not shown) provided in the gas supply unit 11. In addition, the gas supply unit 11 has a function of supplying not only atmospheric gases but also other types of gases (for example, gases having different oxygen concentrations), and a gas type control unit is provided to provide various types of gases. Among them, one kind or plural kinds of gases may be selectively supplied.

And by supplying gas to the gas accommodating part 5, the pressure of the gas accommodating part 5 adds this pressure to atmospheric pressure, and is about 0.11MPa-0.59MPa (1.1kgf / cm < ² > -6kgf / cm) ² ) About a positive pressure state. Thus, by making the gas storage part 5 into a positive pressure, a gas flow from the gas storage part 5 to the liquid storage part 4 through the gas passage 3a is formed. In addition, it is suppressed that the liquid 17 accommodated in the liquid accommodating part 4 leaks in the gas accommodating part 5 from the gas path 3a also by making the gas accommodating part 5 into a positive pressure.

  And by supplying the gas containing oxygen as mentioned above, as shown in FIG. 3, the fine bubble containing oxygen in the opening end 3c by the side of the liquid accommodating part 4 (upper side of FIG. 1) of the gas passage 3a. 16 grows (the process of growing bubbles).

  Next, a predetermined voltage is applied between the first electrode 12 and the second electrode 13 by the plasma power supply unit 15. The voltage to be applied is preferably a voltage (power: about 10 W to about 100 W) that enables glow discharge under atmospheric pressure. At this time, it is preferable to provide a voltage control unit in the plasma power supply unit 15 to control the voltage applied between the first electrode 12 and the second electrode 13.

  Then, by applying a predetermined voltage to the first electrode 12 and the second electrode 13, a gas atmosphere having an atmospheric pressure or higher pressure is provided between the first electrode 12 and the second electrode 13. A discharge occurs. The technique for generating plasma under atmospheric pressure is reported in, for example, Document A (Sachiko Okazaki, “Atmospheric pressure glow discharge plasma and its application”, review lecture: 20th JSPF Annual Meeting).

  Then, due to this discharge (discharge between the surface of the first electrode 12 in contact with the gas and the surface of the second electrode 13 in contact with the liquid), the region of the gas in the liquid 17 (particularly, the opening) Plasma is generated in a region near the gas-liquid boundary surface of the growing bubble 16 at the end 3c, and ozone, hydroxy radicals, and the like are generated by water contained in the liquid and oxygen contained in the gas (generates hydroxy radicals). Process).

  In the present embodiment, plasma is generated by generating a potential difference in the gas in the bubble 16 (the gas in the vicinity of the gas-liquid interface in the liquid 17 of the liquid container 4). As described above, by generating a potential difference in the vicinity of the gas-liquid boundary surface where hydroxy radicals are easily generated (near the open end 3c facing the liquid 17 in the gas passage 3a), it is possible to generate more ozone, hydroxy radicals, and the like. become. In the present embodiment, ozone, hydroxy radicals, and the like can be generated not only in the bubbles 16 near the opening end 3 c facing the liquid 17 in the gas passage 3 a but also in the bubbles 16 sent out to the liquid storage unit 4.

  The ozone, hydroxy radicals, and the like generated in this way are sent out to the liquid storage unit 4 along with the gas flow described above.

  In the present embodiment, the bubbles 16 containing hydroxy radicals or the like are sheared from the ceramic member (partition wall portion) 3 and released into the liquid 17 by the flow of the liquid 17 in the liquid storage portion 4 (bubble releasing step). .

  Specifically, in the liquid storage unit 4 where the bubbles 16 grow, the flow of the liquid 17 (see the arrow 18 in FIGS. 3 and 4) is generated by the introduction of the liquid 17. As shown in FIG. 4, when the liquid 17 flowing in the direction of the arrow 18 hits the growing bubble 16, the flow of the liquid 17 acts as a shearing force on the bubble 16, and the bubble 16 is released into the liquid 17 from the opening end 3c.

  Since the bubbles 16 released in the liquid 17 are fine bubbles, they are diffused to every corner of the liquid 17 without being immediately released into the atmosphere. A part of the diffused fine bubbles 16 is easily dissolved in the liquid 17. At this time, ozone or the like contained in the bubbles 16 is dissolved in the liquid 17, so that the ozone concentration of the liquid rises at a stretch.

  According to Document B (Masayoshi Takahashi, “Improvement of water environment by microbubbles and nanobubbles”, Aquanet, 2004.6), fine bubbles 16 containing ozone and various radicals are usually negatively charged. It has been reported that there are many cases. Therefore, the other part of the bubbles 16 is easily adsorbed by organic substances, oils and fats, dyes, proteins, bacteria, etc. (not shown) contained in the liquid 17. The organic matter or the like in the liquid 17 is decomposed by ozone or various radicals dissolved in the liquid 17 or ozone or various radicals contained in the bubbles 16 adsorbed on the organic matter.

  For example, a hydroxy radical or the like has a relatively large energy of about 120 kcal / mol. This energy is a double bond between a nitrogen atom and a nitrogen atom (N = N), a double bond between a carbon atom and a carbon atom (C = C), or a double bond between a carbon atom and a nitrogen atom (C = N). ) And the like (above 100 kcal / mol). Therefore, an organic substance composed of a bond such as nitrogen or carbon is easily broken and decomposed by this hydroxy radical or the like. Since ozone, hydroxy radicals, and the like that contribute to the decomposition of such organic substances do not have persistence like chlorine and disappear with time, they are also environmentally friendly substances.

  As described above, in the plasma generator 1 according to the present embodiment, the first electrode 12 is disposed in the gas storage unit 5, and the second electrode 13 is at least a portion (first part) that is paired with the first electrode 12. The surface that generates a discharge between the surface of one electrode 12 and the liquid in the liquid storage unit 4 is disposed.

  Then, by generating a discharge between the surface of the first electrode 12 in contact with the gas and the surface of the second electrode 13 in contact with the liquid, plasma is generated in the gas region in the liquid 17 in the liquid container 4. Hydroxyl radicals are generated from water contained in the liquid 17 and oxygen contained in the gas.

  By adopting such a configuration, it is possible to generate a discharge between the first electrode 12 and the second electrode 13 without being significantly affected by the electrical resistance of the liquid 17, so that the gas can be made into plasma more reliably. Thus, a large amount of ozone, radicals and the like can be generated more stably.

  A liquid 17 is introduced into the liquid storage part 4, and a first electrode 12 that generates plasma is disposed in the gas storage part 5 defined by the ceramic member 3. Therefore, the first electrode 12 does not contact the liquid 17 at all and is not affected by the electric resistance of the liquid 17. As a result, a discharge can be stably generated between the first electrode 12 and the second electrode 13, and the gas containing oxygen introduced into the gas storage unit 5 is reliably turned into plasma, and water and oxygen From this, ozone or hydroxy radicals can be generated stably.

  Further, by introducing a gas containing oxygen into the gas storage unit 5, the gas storage unit 5 is brought to a positive pressure, and a gas flow from the gas storage unit 5 to the liquid storage unit 4 through the gas passage 3 a is formed. . Then, ozone, hydroxy radicals, and the like are generated in the bubbles 16 that grow on the opening end 3c facing the liquid 17 in the gas passage 3a by riding on the gas flow.

  That is, ozone, hydroxy radicals, and the like are generated in the gas in the bubbles 16 (the gas in the vicinity of the gas-liquid interface in the liquid 17 of the liquid storage unit 4). A gas containing ozone, hydroxy radicals, or the like is diffused into the liquid 17 as fine bubbles 16. Thereby, after ozone and various radicals are generated, the ozone and various radicals can be efficiently fed into the liquid 17 in a very short time before they disappear.

  Then, the fine bubbles 16 containing ozone and various radicals diffuse into the liquid 17, so that the ozone concentration of the liquid 17 is increased and the bubbles 16 are adsorbed to the organic matter contained in the liquid 17. Thereby, organic matter, bacteria, and the like can be efficiently decomposed by ozone dissolved in the liquid 17 and various radicals contained in the adsorbed bubbles 16.

  Note that if the plasma power supply unit 15 includes a voltage control unit that controls a voltage applied between the first electrode 12 and the second electrode 13, the liquid 17 is interposed between the first electrode 12 and the second electrode 13. The discharge can be stably generated regardless of the fluctuation of the electrical resistance.

  Further, if the gas supply unit 11 has a gas type control unit that controls the type of gas, it is possible to adjust the generation amount of ozone, hydroxy radicals, and the like.

  At this time, if the gas supply unit 11 has a function of supplying air in the atmosphere, the gas can be supplied more easily.

  Moreover, if the gas supply flow rate is controlled by the flow rate control unit, plasma can be generated more stably.

  Next, an example of the cleaning apparatus 40 using the plasma generator 1 will be described with reference to FIGS.

It is formed in a curved shape. The outer blade 56 is formed by drilling a large number of slits (blade holes).

  Further, as the inner blade 55, a dedicated one for the outer blade 56 is installed. Specifically, an inverted U-shaped inner blade 55 is disposed below (inward) the outer blade 56 along the curve of the corresponding outer blade 56 (see FIG. 9).

  The inner blade 55 is attached to, for example, a linear motor (not shown). When the linear motor is driven, the inner blade 55 reciprocates in the left-right direction (longitudinal direction) Y, respectively.

  Then, the inner blade 55 disposed below (inward) the outer blade 56 is moved relative to each outer blade 56 (reciprocating in the left-right direction Y), so that the slit of each outer blade 56 is The body hair inserted in the inside is configured to cut in cooperation with the outer blade 56 and the inner blade 55.

  At this time, the inner blade 55 is relatively moved (reciprocating in the left-right direction Y) while the outer surface 55 a is in sliding contact with the inner surface 56 a of the outer blade 56.

The first electrode 12 and the second electrode 13 are formed of a material having a low coefficient.

For example, the first electrode 12 and the second electrode 13 (the electrode on the side facing at least the sliding surface of the sliding portion among the first electrode and the second electrode) are more rubbed than chromium oxide (Cr ₂ O ₃ ). It can be formed of a material containing Sn or Sn compound having a low coefficient.

  In addition, it can be formed of a material containing Ti or a Ti compound, or can be formed of a material containing carbon or a carbon compound.

  In addition, by coating the surfaces of the inner blade 55 and the outer blade 54, or by laminating different materials for the inner blade 55 and the outer blade 54, the material forming the sliding surface 57 and the inner blade 55 and the outer blade 56 are changed. You may make it differ from the material to form. It is also possible to make the material forming the sliding surface 57 the same as the material forming the inner blade 55 and the outer blade 56.

  Next, the operation of the cleaning apparatus 40 having such a configuration will be described.

  First, the electric razor (hair removal tool) 50 is mounted on the cleaning device 40 so that it is received by the tray 42 with the head portion 51 facing downward.

  Then, a liquid is introduced from the tank 43 through the pipe (liquid introduction path) 21 into the receiving tray 42 and the liquid storage portion 4 of the plasma generator 1.

  Then, a gas having a predetermined flow rate containing oxygen based on air is sent from the gas supply unit 11 into the gas storage unit 5 through the pipe (gas introduction path) 10, and the gas storage unit 5 is brought into a positive pressure state. Thus, a gas flow is formed from the gas accommodating part 5 to the liquid accommodating part 4 through the gas passage 3a.

  Next, discharge is generated between the first electrode 12 and the second electrode 13 by applying a predetermined voltage between the first electrode 12 and the second electrode 13. By this discharge (discharge between the surface of the first electrode 12 in contact with the gas and the surface of the second electrode 13 in contact with the liquid), plasma is generated in the gas region in the liquid 17 of the liquid storage unit 4, Ozone, hydroxy radicals, and the like are generated by oxygen contained in water and gas contained in the liquid 17 (see FIG. 4).

  And the produced | generated ozone and various radicals will be sent out in the liquid stored in the liquid storage part 4 and the receiving tray 42 with the flow of the gas mentioned above. At this time, the growing bubbles are released from the opening end 3c into the liquid as bubbles 16 refined by the miniaturization means, and the fine bubbles 16 released into the liquid diffuse to every corner of the liquid. In other words, the generated cleaning liquid is supplied to the head unit 51 as the target portion to be cleaned. The organic matter or the like attached to the head portion 51 can be efficiently decomposed by ozone or radicals dissolved in the liquid (cleaning liquid), ozone or radicals contained in the bubbles 16, and the like.

  By the way, when a discharge is generated between the first electrode 12 and the second electrode 13, a sputtering phenomenon occurs in which fine particles of the electrode jump out from the first electrode 12 or the second electrode 13. And the microparticles of the electrode which jumped out from each electrode by this sputtering phenomenon will diffuse in the liquid (cleaning liquid). At this time, since the sliding surface 57 of the blade portion (sliding portion) 54 is disposed in the vicinity of the second electrode 13 without being obstructed, minute particles of the electrode in the liquid (cleaning liquid) are placed on the sliding surface 57. It becomes easy to adhere. When the electrode microparticles adhere to the sliding surface 57, the contact area of the sliding surface 57 is reduced in a microscopic environment, and the friction generated when the blade portion (sliding portion) 54 slides is reduced. Thus, seizure of the sliding surface 57 can be suppressed.

  As described above, in the present embodiment, the sliding surface 57 of the blade portion (sliding portion) 54 is the second electrode (the first electrode and the second electrode) with the electric razor (hair removal tool) 50 attached. (At least one of them) 13 is arranged to face each other without being obstructed. Therefore, the fine particles of the electrode jumping out from each electrode due to the sputtering phenomenon are easily attached to the sliding surface 57, and the contact area of the sliding surface 57 can be reduced in a micro environment. As a result, it is possible to reduce the friction generated when the blade portion (sliding portion) 54 slides, and the user does not need to periodically replace and replenish the lubricant. It becomes possible to suppress sticking. Thus, according to the present embodiment, the seizure phenomenon of the blade part (sliding part) 54 of the electric razor (hair removal tool) 50 can be more easily suppressed.

  Moreover, according to this embodiment, the seizure phenomenon of the blade part (sliding part) 54 of the electric shaver (hair removal tool) 50 can be suppressed without using a lubricant, which is not preferable in terms of water quality and environment. Since the cleaning liquid containing the lubricant is not drained, there is an advantage that it is possible to reduce the environmental load of the drainage.

  Further, in the present embodiment, the second electrode 13 is used as a cathode, and the sliding surface 57 of the blade part (sliding part) 54 is arranged so as to face the vicinity of the second electrode 13 without being obstructed. In this way, by making the electrode that is in contact with the liquid on the side facing the sliding surface 57 a cathode that easily emits microparticles, many microparticles can be released into the liquid. As a result, the fine particles of the electrode can be adhered to the sliding surface 57 while cleaning the electric razor (hair removal device) 50, and the cleaning effect of the electric razor (hair removal device) 50 by the liquid cleaning can be improved. While being raised, seizure of the blade portion (sliding portion) 54 can be suppressed.

  In the present embodiment, the first electrode 12 and the second electrode 13 (the electrode on the side of the first electrode and the second electrode facing at least the sliding surface of the sliding portion) are the blade portions (sliding portion). It is made of a material having a lower coefficient of friction than the material forming the 54 sliding surfaces 57. Therefore, the contact state of the sliding portion 57 (contact state between the outer surface 55a of the inner blade 55 and the inner surface 56a of the outer blade 56) in the micro environment is due to the electrode material and the sliding portion material or due to the electrode materials. Thus, seizure of the blade portion (sliding portion) 54 can be further suppressed as compared with the initial cleaning state.

  For example, the first electrode 12 and the second electrode 13 (at least one of the first electrode and the second electrode facing the sliding surface of the sliding portion) includes at least one of Sn and an Sn compound. If formed of a material, Sn or Sn compound adheres to the sliding surface 57. Since this Sn has a characteristic that the friction coefficient is lower than that of a general metal, it becomes possible to reduce the friction generated when the blade portion (sliding portion) 54 slides, and the blade portion (sliding portion) 54. It becomes possible to further suppress the seizure of the material.

  The first electrode 12 and the second electrode 13 (of the first electrode and the second electrode, at least the electrode facing the sliding surface of the sliding portion) include at least one of Ti and a Ti compound. If formed of a material, Ti or a Ti compound adheres to the sliding surface 57. This Ti also has a feature that the coefficient of friction is lower than that of general metals. Furthermore, Ti is a material that is relatively safe for the user's skin because it has a higher physiological affinity than general metals. Thus, if it forms with the material containing at least any one among Ti and Ti compound, it can suppress the seizing of the blade part (sliding part) 54, ensuring the safety | security with respect to skin. become.

  The first electrode 12 and the second electrode 13 (of the first electrode and the second electrode, at least the electrode facing the sliding surface of the sliding portion) include at least one of carbon and a carbon compound. If formed of a material, carbon or a carbon compound adheres to the sliding surface 57. This carbon is also characterized by a lower coefficient of friction than ordinary metals. Furthermore, since carbon has a feature of higher hardness than general metals, the effect of suppressing seizure of the blade portion (sliding portion) 54 can be further maintained.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made.

  For example, in the above embodiment, the ceramic member is exemplified as the partition wall portion in which the gas passage is formed. However, the material of the partition wall portion is not limited to the ceramic member. For example, an appropriate member such as a glass plate that partitions gas and liquid is used, and a member having fine pores with a pore diameter of about 1 μm to 10 μm formed by photolithography and etching is used. Is possible. At this time, a plurality of gas passages may be provided.

  Further, the sliding portion, the liquid storage portion, the gas storage portion, and other detailed specifications (shape, size, layout, etc.) can be changed as appropriate.
