However, when gas phase ozone is generated by the discharge method as described above, there has been a problem that nitrogen oxide (NOx), which is known as one of the causative substances of air pollution, is generated during the ozone generation process. In particular, nitric oxide (NO) has a strong affinity for hemoglobin in the blood and binds to hemoglobin more strongly than oxygen (O ₂ ) and carbon monoxide (CO), thereby inhibiting the supply of oxygen ( In other words, it is known that the substance is extremely harmful to the human body. In addition, since gas phase ozone is difficult to dissolve in water, it is difficult to generate steam ozone water from the gas phase ozone, and the concentration of ozone water could not be sufficiently increased. .

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

  1 is a side view of an iron type cleaning apparatus I as an embodiment of the cleaning apparatus of the present invention, FIG. 2 is a plan view of the iron type cleaning apparatus I of FIG. 1, and FIG. 3 is an iron type cleaning apparatus I of FIG. 4 is a diagram schematically showing a part (heating unit 3) of the iron-type cleaning apparatus I in FIG. 1, and FIG. 5 is a plan view excluding the handle portion in FIG. The ironing type cleaning apparatus I of this embodiment is composed of a main body 1 and a handle portion 2. The handle portion 2 includes an electrode power switch 18 for controlling energization to the electrode 15 to be described later, an electrolysis amount adjusting device 17 for adjusting the electrolysis amount by the electrode 15, an alarm device 20 comprising a buzzer or an alarm, a mist injection switch 21 and the like. Is provided.

  A heating unit 3 is formed at the bottom of the main body 1. The heating unit 3 is made of a metal such as iron. As shown in FIGS. 3 and 4, the heating unit 3 has a bottom surface on which the covering body 30 is formed at a part of the main body 1, and the other part is a flat surface inside the flat surface. Has a built-in heater 5 composed of a heating wire or the like, and is configured so that the flat surface can be heated to a high temperature. Thereby, the flat surface is a heating surface 7 for heating an object to be cleaned such as clothes. The covering 30 has a shape recessed upward from the opening 4 formed on the bottom surface of the heating unit 3, and the opening 3 on the bottom surface is arranged on the object to be cleaned. When the object to be cleaned is closed, a substantially sealed cleaning space S is formed in the covering 30. In addition, examples of the objects to be cleaned include, for example, clothes (clothes), cloth products such as curtains and futons (dirt removal), paper (bleaching), walls and automobiles (dirt removal), or a bath (mold removal). and so on.

  And inside this coating | covering body 30, the discharge port 13 of the discharge part 9 for spraying the water containing the ozone produced | generated by the ozone water production | generation means mentioned later to a to-be-cleaned object, and the ozone for decomposing | disassembling ozone Disassembling means 50 (not shown in FIG. 3) is provided.

  On the other hand, a temperature adjustment switch 19 for adjusting the heating temperature by the heater 5 is provided on the upper surface of the main body 1. Further, a water storage tank 8 is provided in the main body 1 as a storage part for storing water. The water storage tank 8 is formed at a position corresponding to the upper side of the opening 4 of the heating unit 3, that is, at the front end side of the main body 1, and a water inlet 12 for supplying water into the water storage tank 8 is provided on the upper surface thereof. It has been. In addition, a pair of electrolysis electrodes 15 are provided in the water storage tank 8 so as to be immersed in water stored in the water storage tank 8. The electrode 15 for electrolysis is an electrode for generating ozone in the water in the water storage tank 8 by electrolysis, and is connected to a controller 23 as a control device that controls the iron-type cleaning device I and is energized from a power source. Is controlled. That is, the ozone water generating means of the present embodiment includes the water storage tank 8 and the electrode 15, and the ozone is generated in the water of the water storage tank 8 by electrolysis by controlling the power supply to the electrode 15 by the controller 23. Is.

  As described above, the ozone generating means is constituted by the water storage tank 8 and the electrode 15, and ozone is directly generated in the water in the water storage tank 8 by electrolysis by the electrode 15 to generate water containing ozone. The generation of nitrogen oxide (NOx) as in the case of generating gas phase ozone by this discharge method can be reliably avoided.

  In particular, in this case, ozone is generated in water and is in a dissolved state, so that it is possible to easily generate high-concentration ozone water as compared with the case where gas-phase ozone is generated by a conventional discharge method. .

  Further, as shown in FIG. 6, a power plug 34 is attached to one end of the electrode 15, and the tip of the power plug 34 is configured to be detachable from the power socket 35. Thereby, when the electrode 15 deteriorates, it is possible to replace the power plug 34 with a new electrode by removing the power plug 34 from the power socket 35 and removing the power plug 34 attached to the electrode 15.

  In addition, although the water stored in the water storage tank 8 is desirably tap water for ease of use, it is not particularly limited. For example, even water that does not contain any ions such as pure water can be energized and ozone can be generated by sandwiching an ion exchanger or the like between the electrodes 15.

  The discharge unit 9 is a discharge member for injecting water containing ozone generated in the water storage tank 8 in the form of a mist. The operation unit is attached to the handle portion 2 and performs an operation for discharging. As a mist injection switch 21, a supply pipe 25 that enters the water storage tank 8 and is immersed in the water in the water storage tank 8, and the discharge port 13.

  Thereby, when the user operates the mist injection switch 21 of the discharge unit 9 at hand, water containing mist-like ozone is discharged from the discharge port 13 through the supply pipe 25 immersed in the water in the water storage tank 8. Can be injected. At this time, since the discharge port 13 is arranged inside the covering 30, it is possible to avoid the inconvenience that the mist made of water containing ozone leaks outside the covering 30 when sprayed. . The amount of mist injected from the discharge port 13 of the discharge portion 9 is configured to be adjustable by a mist injection switch 21 provided in the handle portion 2. That is, since a predetermined amount of water in the water storage tank 8 is sucked into the supply pipe 25 and discharged from the discharge port 13 for each operation of the mist injection switch 21 by the same principle as the spraying, the mist injection The injection amount of mist can be adjusted by the number of times the switch 21 is operated.

  FIG. 7 is a block diagram of the controller 23 that controls the iron-type cleaning apparatus I of this embodiment. The controller 23 includes a general-purpose microcomputer. On the input side of the controller 23, the electrolytic amount adjusting device 17, the electrode power switch 18, the temperature adjusting switch 19, a temperature sensor 22 for detecting the temperature of the heating surface 7 heated by the heater 5, and ozone are detected. An ozone sensor 60 and the like to be described later are connected. The output side of the controller 23 is connected to the heater 5, the electrode 15, the alarm device 20, the UV lamp 50 (ozone decomposition means), and the like.

  The controller 23 controls the energization of the heater 5 based on the temperature adjustment switch 19 and the temperature sensor 22. Further, the controller 23 controls energization to the electrode 15 based on the electrolytic amount adjusting device 17 and the electrode power switch 18. Specifically, the controller 23 determines the voltage applied to the electrode 15 from the power source as shown in FIG. 8 based on ON / OFF of the electrode power switch 18 and the setting of the electrolysis amount adjusting device 17 (some setting of the electrolysis amount). The ozone concentration of water generated in the water storage tank 8 is controlled to an optimum concentration by the timer 23T for counting the electrolysis time built in the V, the current A and the controller 23.

  In particular, the electrode power switch 18 as in this embodiment is configured so that the electrolysis by the electrode 15 can be turned on / off. For example, if the electrode power switch 18 stops energization (OFF), It is possible to use only the ironing function to stretch the wrinkles of the object to be cleaned, and if the energization to the electrode 15 is started (ON), the cleaning function to decompose and remove the dirt of the object to be cleaned with water containing ozone It becomes possible. Furthermore, when the power supply to the electrode 15 is stopped (OFF) by the electrode power switch 18, the iron type cleaning device I can be used as a steam iron by operating the temperature adjusting device 19 and the mist injection switch 21. is there. Thereby, the presence or absence of ozone generation (that is, the presence or absence of cleaning) can be selected depending on the application.

  On the other hand, FIG. 9 is a diagram showing the relationship between the half-life of ozone dissolved in water and the water temperature. As shown in FIG. 9, it can be seen that the half-life of ozone dissolved in the water becomes shorter as the water temperature rises. That is, it is clear that ozone can exist in water for a longer time as the temperature is lower. FIG. 10 is a graph showing the relationship between the solubility of ozone (the solubility of ozone in 100 g of water) and the water temperature. As shown in FIG. 10, it can be seen that as the water temperature increases, the solubility of ozone dissolved in water decreases, and when the water temperature is + 60 ° C. or higher, the solubility of ozone becomes almost zero. Thereby, it is understood that ozone is diffused into the gas phase by heat. That is, it is clear that it is difficult for ozone to be present in high-temperature steam.

  From the results shown in FIG. 9 and FIG. 10 described in detail above, it has been clarified that ozone is more easily dissolved at a lower water temperature and has a longer half-life. Therefore, it is preferable that the temperature of the water in the water storage tank 9 and the temperature of the water sprayed from the discharge port 13 to the object to be cleaned are at least normal temperature or lower. In the present embodiment, it is assumed that the temperature of water containing ozone discharged from the discharge port 13 toward the object to be cleaned is normal temperature. In this way, by spraying water containing ozone as a mist onto the object to be cleaned, it is possible to avoid the diffusion of ozone into the gas phase due to heat and to allow ozone to exist in water for a long time. The ability to remove dirt from the object to be cleaned can be improved.

  With the above configuration, in order to disassemble and remove the dirt of the object to be cleaned, the power cable 24 of the iron-type cleaning apparatus I is connected to the power supply, and then the electrode power switch 18 is turned on to set the electrolysis amount adjusting apparatus 17. Adjust. Thereby, the water in the water storage tank 8 is electrolyzed and water containing ozone is generated. Next, the opening 4 of the covering 30 formed on the bottom surface of the main body 1 of the iron-type cleaning apparatus I is arranged so as to correspond to the dirty part of the object to be cleaned. As a result, the opening 4 is closed by the object to be cleaned, and the substantially sealed cleaning space S is configured in the above-described substantially sealed covering 30. When the mist injection switch 21 is operated in this state, water containing ozone is injected into the covering 3 from the discharge port 13 in the form of a mist.

  At this time, since the periphery of the dirt of the object to be cleaned becomes the cleaning space S substantially sealed by the opening 4 and the object to be cleaned as described above, the water containing mist-like ozone discharged from the discharge port 13 is It is possible to spray the object to be cleaned located in the cleaning space S without diffusing outside. Thereby, it can be made to act on the dirt which becomes the object effectively. When the water containing ozone is sprayed onto the soiled portion of the object to be cleaned, the organic molecules that make the soil are cut and decomposed into other substances. Thereby, the dirt adhering to the object to be cleaned is removed. In addition, when an item with mold such as a bathroom tile is used as an object to be cleaned, the mold is decomposed when the above-mentioned water containing ozone is sprayed on the area where the mold occurs on the object to be cleaned. (Sterilization). Thereby, the to-be-cleaned object can be sterilized.

  By the way, as described above, the ozone remaining after the object to be cleaned is sprayed on the object to be cleaned and decomposed is evaporated and remains in the cleaning space S (in the covering 30). As described above, ozone has a strong oxidizing power and is useful for sterilization, virus inactivation, deodorization, decolorization and removal of dirt (decomposition of organic matter) as in the present invention, but is harmful to the human body. It is known that That is, when ozone in the covering 30 is directly released to the outside, there is a possibility that the human body may be adversely affected and the ozone odor leaks to the surroundings.

  Therefore, in order to eliminate the inconvenience that vaporized ozone (gas phase ozone) is released to the outside, in the present invention, an ozone decomposing means for decomposing ozone is provided inside the covering 30 together with the discharge port 13. Yes. The ozonolysis means of this embodiment is constituted by a UV lamp 50. This UV lamp 50 is an ultraviolet irradiation means for irradiating ultraviolet rays having a wavelength near 254 nm. The UV lamp 50 according to the present embodiment is arranged in the covering body 30 on the rear side of the discharge port 13, and is configured so as to be able to irradiate the entire interior of the covering body 30 with ultraviolet rays.

  Further, the irradiation of ultraviolet rays by the UV lamp 50 is controlled by the concentration of ozone in the covering 30. In this case, the concentration of ozone in the covering 30 is configured to be detectable by an ozone sensor 60 provided at the rear end of the heating surface 3 of the heating unit 3. The ozone sensor 60 is connected to the controller 23.

  Here, the control operation of the UV lamp 50 of the present embodiment by the controller 23 will be described using the flowchart shown in FIG. First, when the electrode power switch 18 is turned on by the controller 23 and the electrolysis of the water in the water storage tank 8 is started in step S1 (ozone generation electrode electrolysis start shown in FIG. 11), the controller 23 performs step S2. And the ozone sensor 60 detects the ozone concentration in the covering 30 (measures the ozone concentration shown in FIG. 11), and then moves to step S3 where the ozone concentration in the covering 30 is higher than 0.1 ppm. Or not.

  If the ozone concentration is 0.1 ppm or less in step S3, the controller 23 returns to step S2 and repeats the control in steps S2 and S3. On the other hand, if the ozone concentration is higher than 0.1 ppm, the controller 23 proceeds to step S4 to turn on the UV lamp (ultraviolet lamp shown in FIG. 11) 50 and to irradiate ultraviolet rays in the vicinity of 254 nm into the covering 30. In addition to the irradiation, the process proceeds to step S5 to activate the alarm device 20 (that is, the buzzer or alarm is not sounded).

  By irradiating ultraviolet rays having a wavelength of around 254 nm by the UV lamp 50, the ozone in the covering 30 is changed to activated oxygen in a short time [ms]. Since this activated oxygen has a characteristic of reacting with an organic compound that is difficult to decompose only with ozone, the contamination of the object to be cleaned can be further decomposed. Moreover, since the lifetime of this activated oxygen is less than microseconds, it is quickly decomposed and removed.

  Moreover, since the humidity in this covering body 30 becomes 80% or more by discharging the water containing ozone into the covering body 30 which is the substantially sealed cleaning space S, the activated oxygen and the moisture in the air Reacts with each other to generate hydroxy radicals (OH.). Hydroxyl radical is a highly reactive substance, so it can promote the reactivity with organic compounds (dirt), and can also strongly decompose bacteria. Thereby, in addition to the removal of dirt on the object to be cleaned, sterilization can also be performed. In addition, since the lifetime of the hydroxy radical is 1 to 1 / 1,000,000 seconds, it is quickly decomposed and removed.

  Thus, when the ozone concentration in the cleaning space S is higher than 0.1 ppm, the UV lamp 50 irradiates the cleaning space S with ultraviolet light having a wavelength of about 254 nm, and the vapor phase ozone in the cleaning space S Can be disassembled. As a result, it is possible to avoid inconvenience that ozone is released to the outside of the cleaning space S and ozone odor leaks to the outside or adversely affects the human body, and the safety of the user can be ensured. It becomes like this.

  In particular, the ozone decomposing means is an ultraviolet ray irradiating means constituted by the UV lamp 50 as in this embodiment, so that the apparatus for decomposing ozone can be surely produced at low cost without complicating or increasing the size of the apparatus. It becomes possible to decompose ozone.

  When the ozone in the covering 30 detected by the ozone sensor 60 is lowered to a concentration of 0.1 ppm or less that does not affect the human body, the controller 23 turns off the UV lamp 50 and irradiates the ultraviolet rays described above. Stop and stop the alarm device 20, and return to step S2 to repeat the control described above. It is assumed that the controller 23 always performs the above-described ozone concentration detection operation in the covering 30 by the ozone sensor 60 while the electrode power switch 18 is ON.

  On the other hand, in the iron type cleaning apparatus I of this embodiment, the metal oxide catalyst 55 is applied to the entire heating surface 7. This metal oxide catalyst 55 is for decomposing ozone in the same manner as the UV lamp 50. The metal oxide catalyst 55 is made of manganese dioxide, ferrous oxide, nickel oxide, cobalt oxide, manganese dioxide, or the like. The metal oxide catalyst 55 is not limited to the above, but includes titanium, titanium oxide, silicon, silicon oxide, zirconium, zirconium oxide, a composite compound of titanium, silicon and zirconium, a composite oxide of titanium, silicon and zirconium, and manganese. , Iron, cobalt, nickel, silver, platinum, palladium, rhodium, and other transition metals, or an element including two or more or a composite (transition metal oxide) including an oxide. Absent.

  In this case, the metal oxide catalyst 55 is heated by heating the heating surface 12 to +50 to + 150 ° C., and ozone is decomposed by the metal oxide catalyst 55 in 0.5 to 5 seconds. As shown in (1) to (3) of FIG. 12, there are three main decomposition mechanisms in which ozone is decomposed by the metal oxide catalyst 55, and any of the reaction mechanisms (issuer: Realize Inc., issue) Sun: Dec. 25, 1992, book name "Ozone Yearbook"). In this way, by applying the metal oxide catalyst 55 to the entire heating surface 7, ozone can be decomposed by the metal oxide catalyst 55 in addition to the UV lamp 50 described above. In particular, when the cleaning device of the present invention is applied to an iron like the iron-type cleaning device I of the present embodiment, the main body 1 is quickly moved on the object to be cleaned. There was a possibility that the gas phase ozone could not be completely decomposed and remained, but the metal oxide catalyst 55 can reliably decompose the gas phase ozone remaining.

  In this embodiment, as the ozonolysis means, the metal oxide catalyst 55 is applied to the entire heating surface 7 of the heating unit 3 in addition to the UV lamp 50. Claims 1 to 5 and Claims In the invention according to any one of 8, ozone may be decomposed only by the UV lamp 50. Further, in the invention according to claim 1 or claim 5 to claim 8, an ozonolysis means is constituted by the metal oxide catalyst 55 without providing the UV lamp 50, and the metal oxide catalyst 55 It is also effective for decomposing ozone.

  Moreover, in the said Example 1, the iron type washing | cleaning apparatus I which applied the washing | cleaning apparatus of this invention to the iron was demonstrated. Thus, the versatility of the cleaning device of the present invention can be enhanced by applying the cleaning device to the iron. However, the cleaning device of the invention of claims 1 to 3 or claim 8 is not limited to the application to an iron, and may be constituted by a single cleaning device that only cleans an object to be cleaned. Absent.

  For example, in FIG. 13, the entire body 1 has an opening 4 at the bottom, and when the opening 4 is closed by the object to be cleaned, the covering that constitutes the cleaning space S that is substantially sealed with the object to be cleaned. The cleaning device W is a body 30. In FIG. 13, the same reference numerals as those in FIGS. 1 to 12 denote the same or similar effects or actions. In this cleaning device W, the inside of the handle portion 2 attached to the upper portion of the main body 1 is hollow inside, and this hollow portion is the water storage tank 8. Reference numeral 70 denotes a battery as a power source for energizing the electrode 15. In this case, when the user operates a mist injection switch 21 provided on the upper surface of the handle portion 2, mist-like ozone is discharged from the discharge port 13 via the supply pipe 25 immersed in the water in the water storage tank 8. The contained water is sprayed toward the object to be cleaned.

  Also in this embodiment, the UV lamp 50 is controlled by the controller 23 as in the above embodiment. Since the control operation is the same as that shown in FIG. 11 in the above embodiment, the description is omitted here.

  In addition, the cleaning apparatus shown in each of the above embodiments is configured to discharge water containing ozone. Since this ozone has a strong oxidizing power and deteriorates the material, at least an olefin-based, acetylene-based double bond, Alternatively, the device is composed of materials other than compounds containing triple bonds, molecules with aromatic carbon rings, amines, sulfides (mercaptan, sulfide, etc.), sulfonic acids, phosphates, alcohols, ethers, and aldehydes.
