Description

The present invention relates to a human body with the direction to be thereby able Rumi strike spraying apparatus and it can spray a mist existing room.

  In recent years, in order to keep the human body clean, various devices have been devised as devices for cleaning the human body.

  For example, Japanese Utility Model Laid-Open No. 7-17391 (Patent Document 1) describes a local cleaning apparatus with a silver ion electrolysis apparatus attached to a toilet as a human body cleaning apparatus. This local cleaning apparatus with a silver ion electrolyzer performs local cleaning with silver ion water.

  For example, Japanese Patent Laying-Open No. 2004-208748 (Patent Document 2) describes a lower limb bathing apparatus using silver ions as a human body cleaning apparatus. This lower limb bathing apparatus removes dirt and germs between toes and toes.

  For example, Japanese Patent Application Laid-Open No. 2004-160130 (Patent Document 3) describes a method of purifying a body by spraying a purified mist having a deodorizing liquid or a sterilizing action directly on the body or hair with an atomizer. Has been.

Moreover, although it does not wash a human body, in Japanese translations of PCT publication No. 2004-524875 (patent document 4), the humidification method and humidifier which atomize silver ion water, spray it in the air, humidify and sterilize the air Is described.
Japanese Utility Model Publication No. 7-17391 JP 2004-208748 A JP 2004-160130 A JP 2004-524875 A

  However, in the human body cleaning apparatus according to Japanese Utility Model Laid-Open No. 7-17391 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2004-208748 (Patent Document 2), silver ions can be attached only to a part of the human body such as a local part or a foot. Because it was not possible, only a part of the human body could be antibacterial. Moreover, it was not possible to move on foot during the process of attaching silver ions.

  Moreover, in the method of purifying the body by Unexamined-Japanese-Patent No. 2004-160130 (patent document 3), purifying liquids, such as a disinfection liquid, are spouted from the spraying opening provided in the spraying holder. I had to operate it myself and spray it on my body.

  In the humidification method and humidifier described in JP 2004-524875 A (Patent Document 4), air can be humidified and sterilized, but silver ions are adhered to the surface of the human body, the inner wall, floor, ceiling, etc. of the room. Therefore, it is not assumed that antibacterial and sterilization is performed.

The present invention has been made in view of the above points. The object of the present invention is to attach antibacterial metal ions to as wide a range of the human body as possible without performing the operation of spraying mist on the body. to provide a luminal strike spray device and room with it.

Mist spray apparatus of the present invention, there in the mist spray apparatus having a metal ion water generation means for generating a metal ion water to a metal ion having antibacterial properties is added to water, and atomizing means for atomizing the water The metal ion water or the water is atomized by the atomizing means to form a mist, and has an operation mode in which the mist is sprayed for a predetermined period toward the human body. In the operation mode, the metal ion is attached to the human body. Further, the metal ion concentration of the metal ion water contained in the mist sprayed at the later stage of the predetermined period is higher than the previous period .

According to this configuration, since the metal ion water having antibacterial properties is atomized to form a mist and sprayed in the direction in which the human body exists, the mist adheres to a wide range of the human body, and the human body can be antibacterial. Moreover, since metal ion water with high concentration adheres, it is possible to compensate for the amount of metal adhesion in a portion where metal ion adhesion is small.

In the mist spray apparatus of the present invention preferably contains a metal ion only mist sprayed late in the predetermined time period.

  With such a configuration, silver ions can be attached to the human body, and consumption of metal ions can be suppressed as compared with the case where metal ion water is always sprayed.

In the mist spraying apparatus of this invention, it is preferable to provide the atomization nozzle which can change the spraying direction of mist by the detection of the human sensor which detects presence of a person .

  With such a configuration, since the metal ion water can be sprayed in the direction in which the person exists, the possibility that the metal ion water is not sprayed depending on the place where the person exists can be reduced. .

  The room according to the present invention includes a mist spraying device having the above-described configuration.

  According to the room of the present invention, the antibacterial property is applied not only to the human body but also to the inner wall, ceiling and floor surface of the room, chairs placed in the room, etc. by the metal ion water having antibacterial properties sprayed from the mist spraying device. The metal ion which has can be made to adhere and generation | occurrence | production of mold | fungi and slime can be prevented. In particular, it is possible to prevent the occurrence of mold and slime even in the corners of rooms and where water tends to remain, such as drain outlets.

  According to this invention, the silver ion can be made to adhere to the wide range of a human body by atomizing the metal ion water which has antibacterial properties, making it mist shape, and spraying in the direction where a human body exists. In addition, in the case of a room equipped with a mist spraying device, metal ions having antibacterial properties can be attached to the interior walls, ceiling and floor of the room, chairs placed in the room, etc. It is possible to prevent the occurrence of mold and slime in the part.

  DESCRIPTION OF EMBODIMENTS Embodiments of a mist spraying method, a mist spraying apparatus, and a room equipped with the same will be described with reference to the drawings.

  A mist spraying apparatus for carrying out the mist spraying method of the present invention and a first embodiment of a room equipped with the same will be described with reference to FIG. FIG. 1 is a schematic perspective view of a room equipped with the mist spraying apparatus of the present invention. In the first embodiment, a mist sauna device is used as the mist spraying device, and a sauna room is used as an example of the room. As shown in FIG. 1, a mist sauna device 1, a seating portion 101, and the like are disposed inside the sauna room 100. The mist sauna device 1 is installed on the wall surface 12 above the sauna room 100. Here, the top surface, floor surface, and side surfaces of the sauna room 100 are collectively referred to as the wall surface 12.

  FIG. 2 is a schematic cross-sectional view of the mist sauna device 1 installed on the wall surface 12. As shown in FIG. 2, a mist sauna device 1 includes a silver ion elution unit 2 that is metal ion water generating means, a three-way valve 3, a water supply valve 4, and a temperature sensor 5 that measures water temperature inside a housing 1a. A heater 6 as a heating means, a silver ion elution unit 2, a three-way valve 3, a water supply valve 4, a temperature sensor 5 and a heater 6, a water spray pipe 9, an atomizing nozzle 11, A human sensor 13 is provided as a means for detecting the presence of water, and a water guide pipe 8 and a drain pipe 10 partially projecting from the outside of the housing 1a are provided. The atomizing nozzle 11 can change the direction of the nozzle by a driving motor (not shown). As this direction changing mechanism, for example, a known pan / tilt mechanism used for changing the direction of a camera such as a door phone may be used, and the details will not be described. Further, as the human sensor 13, for example, by using an infrared detection device described in Japanese Patent Laid-Open No. 1-110282 or an optical object detection device described in Japanese Patent Laid-Open No. 1-277796, The direction (position) in which a person exists can be detected. Of course, it is also possible to use means for confirming the direction (position) where a person is present on the image using a CCD or the like. The human sensor 13 and the driving motor are controlled by the control unit 7.

  One end of the water conduit 8 is connected to the three-way valve 3 inside the housing 1a, and the other end is connected to a water pipe (not shown) that is, for example, a water supply pipe outside the housing 1a. ing. In addition, a water supply valve 4, a temperature sensor 5, and a heater 6 are arranged in this order from the three-way valve 3 side to the outside (water pipe side) in the water conduit 8 in the housing 1a. That is, the water led from the water pipe to the water guide pipe 8 reaches the three-way valve 3 through the heater 6, the temperature sensor 5, and the water supply valve 4 in this order. The heater 6 heats the water flowing through the water conduit 8, and the temperature sensor 5 measures the temperature of the water guided from the water pipe to the water conduit 8. Further, when the water supply valve 4 is opened, water flows from the water pipe into the water guide pipe 8, and when the water supply valve 4 is closed, the water is stopped.

  One end of the drain pipe 10 is connected to the three-way valve 3 inside the casing 1a, and the other end is connected to, for example, a sewer pipe (not shown) outside the casing 1a.

  One end of the water spray tube 9 is connected to the three-way valve 3, and the other end is connected to the atomizing nozzle 11. In order to be able to change the nozzle direction of the atomizing nozzle 11, it is preferable that the watering pipe 9 uses a hose having a flexible structure. Or you may use a bellows hose etc. for the connection of the atomization nozzle 11 and the water sprinkling tube 9. FIG. A silver ion elution unit 2 is disposed in the middle of the water spray tube 9.

  The three-way valve 3 guides water flowing from the water guide pipe 8 to either the water spray pipe 9 or the drain pipe 10. When led to the water spray pipe 9, the water is sprayed as mist in the sauna room 100 through the atomizing nozzle 11. Further, when led to the drain pipe 10, the water is drained to the sewer pipe.

  The water conduit 8 is not a water pipe, but is connected to a hot water pipe of an external hot water supply facility (for example, a water heater or a boiler) so that hot water, not water, is guided into the water conduit 8. Also good. In this case, since hot water, which is water having a high temperature, is supplied to the mist sauna device 1, the heating means (the heater 6 in this embodiment) may not be provided. However, providing the heating means has the following advantages, for example. The water that is led from the hot water supply equipment installed outside (outdoor) through the pipe to the water guide pipe 8 immediately becomes a desired water temperature (a temperature at which a person does not feel cold, for example, a temperature between 30 ° C. and 45 ° C. In such a case, the temperature of the water can be raised by the heating means (heater 6 in this embodiment). Therefore, compared to the case where no heating means is provided, the time until the mist is sprayed is reduced. It can be shortened.

  FIG. 3 is a schematic sectional view of the silver ion elution unit 2. 3A is a horizontal schematic cross-sectional view, and FIG. 3B is a vertical schematic cross-sectional view. As shown in FIGS. 3 (A) and 3 (B), the silver ion elution unit 2 has a case 21 formed of an insulating material such as a synthetic resin. The case 21 has, for example, a size of 20 mm. Plate-like silver electrodes 22a and 22b, which are metal electrodes having a size of about 50 mm and a thickness of about 1 mm, are arranged so as to be substantially parallel with a distance of about 5 mm. Further, connection terminals 23a and 23b are integrally formed on the silver electrodes 22a and 22b, respectively. The connection terminals 23a and 23b are connected to the control unit 7 by wiring (not shown), for example. The case 21 is provided with an inlet 24 through which water flows in and an outlet 25 through which water flows out. Water flows from the inlet 24 into the case, and water flows out of the case through the outlet 25. be able to. That is, water flows parallel to the longitudinal direction of the silver electrodes 22a and 22b.

When a voltage is applied between the silver electrodes 22a and 22b by the control unit 7 in a state where the silver electrodes 22a and 22b are immersed in the water, the reaction of Ag → Ag ⁺ + e ⁻ occurs at the silver electrode on the anode side. occurs, silver ions (Ag ⁺⁾ are eluted into water. If silver ions (Ag ⁺ ) continue to elute, the silver electrode on the anode side will wear out. Silver ions eluted from the silver electrode 22a or 22b exhibit excellent bactericidal and antifungal effects. Therefore, silver ion water acts as antibacterial water having antibacterial properties. The antibacterial or sterilization here includes not only sterilization and antibacterial bacteria and fungi but also inactivation of viruses. In addition, the fact that the virus is inactivated by silver ions is described in “Silver Ion Water LA Criskey New Japan Foundry Association (Publishing Association) 1993”.

On the other hand, in the silver electrode on the cathode side, a reaction of H ⁺ + e ⁻ → 1 / 2H ₂ occurs, hydrogen is generated, and calcium contained in water is deposited on the surface of the silver electrode as a scale of calcium compound such as calcium carbonate. To do.

  In addition, silver chloride and sulfide, which are component metals of the electrode, are generated on the surface. Therefore, when used for a long time, a scale such as calcium carbonate, chloride, or sulfide is deposited thickly on the electrode surface, preventing the elution of silver ions, which are metal ions. For this reason, the elution amount of silver ions becomes unstable, and the electrode wear becomes uneven. Accordingly, the control unit 7 periodically reverses the polarity of the applied voltage between the silver electrodes 22a and 22b of the silver ion elution unit 2 (for example, every 20 seconds), thereby attaching the scale to the silver electrodes 22a and 22b. Only one silver electrode is prevented from being consumed.

  In addition to the silver electrode, the metal electrode may be any metal that can elute metal ions having antibacterial properties. Specifically, copper, an alloy of silver and copper, zinc, or the like can be selected. . Silver ions eluted from the silver electrode, copper ions eluted from the copper electrode, or zinc ions eluted from the zinc electrode exhibit excellent bactericidal and antifungal effects. Silver ions and copper ions can be simultaneously eluted from the alloy of silver and copper. The anode may be an electrode that elutes metal ions, and the cathode may be an electrode that does not elute metal ions. When the electrode form is composed of two or more (plural) electrodes, all may be metal electrodes of the same material, either one is a metal electrode, and the other electrode is a non-metal electrode (for example, a carbon electrode) , Conductive plastic electrode, etc.) or a plated electrode. Furthermore, a metal electrode that is difficult to ionize (for example, a titanium electrode, a platinum electrode that is a noble metal, a gold electrode, or the like) may be used. Or you may be comprised from the some metal electrode (for example, silver electrode, copper electrode, etc.) from which a material differs.

  The elution of silver ions is performed by so-called constant current control in which the current value is constant and the voltage application time is adjusted. The silver ion concentration of silver ion water can be controlled by the amount of electricity flowing between the electrodes and the amount of water. For example, in the case of the silver ion elution unit 2 having the above-described structure, in order to obtain 90 ppb of silver ion water, the amount of water may be 1 L / min and the current value may be 3 mA. Further, in order to obtain 600 ppb of silver ion water, the amount of water may be 1 L / min and the current value may be 10 mA. The elution amount of silver ions is approximately proportional to the amount of electricity (C) = constant current value (A) × time (sec), except in the low current region. Further, if the amount of water is constant, there is a correlation between the amount of electricity and the silver concentration of the obtained silver ion water, so that silver ion water having a desired concentration can be obtained by adjusting the current value. In this manner, a desired silver ion concentration can be obtained by flowing a predetermined current through the silver electrodes 22a and 22b through a constant flow of water. Further, since the flow rate can be substantially fixed by the structure of the water supply valve, the atomizing nozzle, or the like, it is possible to generate substantially constant silver ion water by flowing a constant current. In addition, it is preferable to obtain | require beforehand the combination of an electric current value and time so that silver ion water of various density | concentrations can be obtained.

  These silver ions, copper ions, and zinc ions are not irritating to the human body and have low toxicity. Therefore, even if a person touches the mist, it can be used for a person. In addition, since metal ions and their compounds are difficult to volatilize, volatilization is promoted by raising the temperature or ventilating, such as hypochlorous acid, and the effect is lost or an unpleasant odor is generated. It does not occur.

  Further, in the metal ion water generating means having a form like the silver ion elution unit 2 described above, elution / non-elution of silver ions as metal ions can be selected depending on whether or not voltage is applied. Further, the elution amount of silver ions can be controlled by controlling the voltage application time. Therefore, for example, compared to a method of eluting metal ions from a metal ion carrier such as zeolite, selection of whether or not to introduce metal ions and adjustment of the concentration of metal ions can all be performed electrically, thereby improving usability.

  Then, the mist spray start operation | movement of the mist sauna apparatus 1 is demonstrated. FIG. 4 is a flowchart showing a first spray operation start routine of the mist sauna apparatus. This operation is controlled by a microcomputer (not shown) provided in the control unit 7.

  The first spray operation start routine is started from S100, and the process proceeds to S101. In S101, the temperature sensor 5 causes the water temperature in the water conduit 8 to be equal to or higher than a predetermined temperature (a temperature at which a person does not feel cold, for example, between 30 ° C. and 45 ° C., in this embodiment, 45 ° C.). Confirm. If the water temperature is lower than the predetermined temperature (if No), the process proceeds to S106 described later. If the water temperature is equal to or higher than the predetermined temperature (Yes), the process proceeds to S102. In S102, the three-way valve 3 is switched to the water pipe 9 side, and the process proceeds to S103.

  In S103, the water supply valve 4 is opened, and the process proceeds to S104. At this time, the water (hot water) in the water conduit 8 is guided to the water spray tube 9. In S104, energization of the silver electrodes 22a and 22b of the silver ion elution unit 2 is started. At this point, silver ions are added to the water (hot water) in the water spray tube 9, and silver ion water is generated. This silver ion water passes through the water spray tube 9, is misted by the atomizing nozzle 11, and is discharged into the sauna room 100. At this time, if the direction (position) where the person exists is detected by the human sensor 13, the control unit 7 drives the driving motor (not shown) to move the atomizing nozzle 11 in the direction where the person exists. Turn. At this time, if the presence of a person is detected at a plurality of positions, the atomizing nozzle 11 is swung, or the direction of the atomizing nozzle 11 is changed every predetermined time (for example, every 30 seconds). What is necessary is just to change sequentially to (position). At this time, if the presence of a person is not detected, the direction of the atomizing nozzle 11 may be changed, may not be changed, or may be swung. Thereafter, the process proceeds to S105. In S105, the first spray operation start routine is exited.

  In S101, if the water temperature is lower than the predetermined temperature (if No), the process proceeds to S106. In S106, the heater 6 which is a heating means is energized, and the process proceeds to S107. In S107, the three-way valve 3 is switched to the drain pipe 10 side, and the process proceeds to S108. In S108, the water supply valve 4 is opened, and the process proceeds to S109. At this time, the water (hot water) in the water guide pipe 8 is guided to the drain pipe 10.

  In S109, the water temperature is checked while adjusting the water amount by adjusting the energization amount of the heater 6 and the opening of the water supply valve 4 so that the water temperature is close to a predetermined temperature. If the water temperature is lower than the predetermined temperature (45 ° C. in this embodiment) (if No), the process returns to S109. If the water temperature is equal to or higher than the predetermined temperature (Yes), the process proceeds to S110. In S110, the three-way valve 3 is switched to the water pipe 9 side, and the process proceeds to S104. At this time, the water (hot water) in the water conduit 8 is guided to the water spray tube 9.

  In S104, energization of the silver electrodes 22a and 22b of the silver ion elution unit 2 is started. At this point, silver ions are added to the water (hot water) in the water spray tube 9, and silver ion water is generated. This silver ion water passes through the water spray tube 9, is misted by the atomizing nozzle 11, and is discharged into the sauna room 100. At this time, if the direction (position) where the person exists is detected by the human sensor 13, the control unit 7 drives the driving motor (not shown) to move the atomizing nozzle 11 in the direction where the person exists. Turn. At this time, if the presence of a person is detected at a plurality of positions, the atomizing nozzle 11 is swung, or the direction of the atomizing nozzle 11 is changed every predetermined time (for example, every 30 seconds). What is necessary is just to change sequentially to (position). At this time, if the presence of a person is not detected, the direction of the atomizing nozzle 11 may be changed, may not be changed, or may be swung. Thereafter, the process proceeds to S105. In S105, the spray operation start routine is exited.

  In this way, the silver ion water mist released into the sauna room 100 adheres to the wall surface 12 in the sauna room 100, the seat 101 provided in the sauna room 100, the basin, and the like, Due to the antibacterial, antifungal and bactericidal properties, the wall 12, the stool 101, the basin and the like are antibacterial.

In order to maintain the mist, it is necessary to use a large amount of water. For example, 550 mL of water is required to make a room having a room temperature of 40 ° C. and a volume of 10 m ³ have a relative humidity of 100%, and 550 mL or more of water is required to make mist present in the air. . That is, in order to use as the sauna room 100, it is necessary to maintain mist and to supply water continuously. Therefore, the amount of water supply is controlled by controlling the water supply valve 4 by connecting the mist sauna device to at least one of the water supply pipe or the hot water supply pipe (in this embodiment, connected to a water pipe that is a water supply pipe). It has a configuration.

  In this way, it is not necessary to provide a large tank that can store a large amount of water. In addition, even when adjusting (heating) the water temperature, it is only necessary to adjust the water temperature by heating the water passing through the pipe. Therefore, the required heating means capacity (for example, output (W) in the case of a heater, gas) In this case, the calorie (kcal)) can be reduced as compared with the capacity required for adjusting the temperature of a large amount of water stored in the tank.

  Instead of the atomizing nozzle 11, silver ion water may be atomized by an ultrasonic vibrator or a venturi effect. In this case, as a method for changing the spraying direction of the atomized mist, for example, a known blowing direction changing mechanism using a vertical louver and a horizontal louver, which is often used in an indoor unit of an air conditioner, may be used.

  Subsequently, the antibacterial effect using silver ions will be described with reference to Tables 1 and 2.

  Table 1 is a table derived from “bacterial and fungicidal vol. 22, No. 9, pp. 531-536, 1994” and is a table showing “antibacterial effect of silver ions against E. coli”. . Table 2 is a table showing “the antibacterial effect of silver ions on cladosporium cladosporioides” actually tested by the present inventors. In any of the test methods, silver ion water and a bacterial solution were brought into contact with each other, and the initial number of bacteria was compared with the number of bacteria after 24 hours. As test species, Escherichia coli (E. coli), which is a microorganism present in the sauna room 100 and in the bathroom, and Cladosporium cladosporioides known as black mold are used. The “logarithmic difference from 0 ppb” in Table 1 means the logarithmic difference between 0 ppb bacterial count after 24 hours and 10 ppb bacterial count after 24 hours, 0 ppb bacterial count after 24 hours and 24 hours The logarithmic value difference with the subsequent 100 ppb number is shown, and the “logarithmic value difference with 0 ppb” in Table 2 is the difference between the 0 ppb number after 24 hours and the 90 ppb number after 24 hours. Numerical difference, logarithmic difference between 0 ppb bacterial count after 24 hours and 600 ppb bacterial count after 24 hours.

  As shown in Table 1 and Table 2, it was effective against both bacteria. Moreover, it turns out that an antimicrobial effect is so high that the density | concentration of silver ion is high.

  Then, the antibacterial effect with respect to the microbe which exists in the human body using silver ion is demonstrated using Table 3, Table 4. FIG.

  Both Table 3 and Table 4 were actually tested by the present inventor. Table 3 is a table showing "the antibacterial effect of silver ions against Candida albicans". It is a table | surface which shows the "antibacterial effect of the silver ion with respect to Trichophyton mentagrophytes". In any of the test methods, silver ion water and a bacterial solution are brought into contact with each other, and the initial number of bacteria is compared with the number of bacteria after a predetermined time. As the test bacteria species, bacteria that propagated on the human skin and could cause harm were used. The “logarithmic difference with 0 ppb” in Table 3 is the difference between the logarithmic value of 0 ppb after 10 minutes and the number of 90 ppb after 10 minutes, and the number of bacteria with 0 ppb after 10 minutes and 10 minutes. The logarithmic value difference with the subsequent 600 ppb number is shown, and the “logarithmic difference with 0 ppb” in Table 4 is the difference between the 0 ppb number after 24 hours and the 90 ppb number after 24 hours. Numerical difference, logarithmic difference between 0 ppb bacterial count after 24 hours and 600 ppb bacterial count after 24 hours.

  As shown in Table 3 and Table 4, it was effective against both bacteria. Moreover, it turns out that an antimicrobial effect is so high that the density | concentration of silver ion is high.

  In addition, as temperature of the mist sprayed from the mist sauna apparatus 1 in the sauna room 100, 30-45 degreeC is preferable so that a person may not feel cold. This temperature is originally a temperature suitable for the propagation of microorganisms and may cause the growth of bacteria in the sauna room 100. However, if the mist of the present invention contains metal ions having an antibacterial effect, such a thing is possible. There is no. Moreover, when using silver ion water as metal ion water, it is known that the tolerance with respect to silver of bacteria will fall, so that the water temperature of silver ion water becomes high. This is publicly known and is described in “Silver-ion water LA Krissky New Japan Foundry Association (Publishing Association) 1993”.

  Thus, if the mist sauna apparatus 1 which is a mist spraying apparatus is used, silver ion water (metal ion water containing the metal ion which has antibacterial property) is atomized, and the direction (position) where a person exists by the human sensitive sensor 13 Is detected, the atomization nozzle 11 is automatically directed in the direction (position) in which the person is present in the sauna room 100 and the silver ion water mist is sprayed, so that the mist can be concentrated around the human body. Mist is easily adhered to a wide range of the surface (portions exposed to the mist such as the head, neck, arms, chest, abdomen, back, buttocks, and feet). Further, a person can freely move around in the sauna room 100, and does not need to stay in one place, and can enjoy antibacterial effects on a wide range of the human body surface while enjoying the sauna.

  Furthermore, the wall surface 12 in the sauna room 100, the wash basin, the chair, etc. placed in the sauna room 100 can be coated with silver ion water. Here, the coating means that silver ion mist is adhered to a part or all of the surface of the wall surface 12 in the sauna room 100 or the washbasin placed in the sauna room 100. Thus, the adhered silver ion mist remains as a silver compound even after drying and brings about an antibacterial action. Moreover, silver ion water can be made to adhere also to a drain ditch or a drain outlet.

  Furthermore, when the presence of a person is not detected, the direction of the atomizing nozzle 11 is changed to a position near the midpoint of the operable range of the atomizing nozzle 11 or changed to a position where spraying can be performed near the center of the room. Alternatively, it is possible to spray silver ion mist evenly in the sauna room 100 by changing randomly or swinging.

  Further, the inside of the sauna room 100 and the bathroom are exposed to water over a wide range such as the indoor wall surface 12 (top surface, bottom surface, etc.). It is difficult to clean the ceiling and the high part of the wall. By attaching silver ion mist, it is possible to reduce the growth of mold and the occurrence of slime on the high part of the ceiling and the wall. In particular, in the case of a mist sauna, the portion that comes into contact with water extends over the entire room. Under such conditions, water is likely to remain for a long period of time, and in such a place, slime and odor due to the growth of bacteria are likely to occur, and mold is likely to occur. However, by using silver ion water (metal ion water containing antibacterial metal ions) for the mist, the antibacterial and antifungal action of silver ions can prevent slime and mold even if water remains. it can.

  In the present embodiment, in S104, the silver electrodes 22a and 22b of the silver ion elution unit 2 are energized, and silver ions are added to the water (hot water) in the water spray tube 9, thereby generating silver ion water. However, the presence sensor 13 detects whether or not a person is present in the sauna room 100, and when the person is in the sauna room 100, silver ion water is generated and silver ion water is generated. The mist may be atomized and sprayed, and if there is no person, the mist may not be sprayed. Alternatively, when a person is in the sauna room 100, silver ion water is generated, and the silver ion water is misted and sprayed. When there is no person, a mist not containing silver ions is sprayed. Also good. In this way, silver ions can be attached to the human body, consumption of metal ions can be suppressed, and consumption of the silver electrodes 22a and 22b can be suppressed compared to the case where metal ion water is always sprayed. it can.

  In addition, a heating device may be provided in the sauna room 100.

  Further, in the present embodiment, the description has been given using the sauna room 100 as a room including the mist sauna apparatus 1 which is a mist spraying apparatus. However, the room may not be a sauna exclusive room, for example, a mist sauna apparatus 1 in a bathroom or the like. May be provided. The sauna room and bathroom may be for business use or home use. Furthermore, it may be a device that is not installed near the ceiling but is installed on the floor.

  Furthermore, the “direction in which a person exists” includes a direction in which a person probably exists. For example, the direction in which a person is likely to be present in a sauna room or bathroom (such as the direction where a seat 101 or a washing place for washing the body is installed. This direction is set by the user, and the setting data is controlled by the control unit. 7 may be stored in advance in the case where the place where the user such as the seat 101 or the washing place can be limited because of the structure.) Spray the mist on. Alternatively, instead of spraying directly on a person, the mist may be naturally dropped by gravity by spraying in a substantially horizontal direction toward the direction in which the person is supposed to exist. By doing in this way, it is not necessary to attach the human sensor 13, leading to cost reduction.

  Next, another mist spray start operation of the mist sauna apparatus 1 which is a mist spray apparatus will be described as a second embodiment of the mist spray apparatus of the present invention and a room including the mist spray apparatus. In the second embodiment, the same reference numerals are given to the same components as those described in the previous embodiment, and the description thereof is omitted. In the second embodiment, the mist sauna device 1 has an operation mode for a first certain period. The first fixed period operation mode is, for example, that the mist sauna device 1 is operated only during a fixed period to spray the mist, but in this fixed period, the last predetermined time before ending the spraying (hereinafter, This is a mode in which a mist containing metal ions is sprayed only during the first operation time), and a mist containing no metal ions is sprayed otherwise. This fixed period (for example, 30 minutes, 60 minutes, etc.) and the first operation time (the last 15 minutes, the last 20 minutes, etc.), which is a predetermined time, may be fixed or can be arbitrarily determined by the user. Anyway. The relationship between the first operation time and the fixed period is “first operation time ≦ fixed period”.

  FIG. 5 is a flowchart showing a routine of a first fixed period operation mode of the mist sauna device, and FIG. 6 is a flowchart showing a second spray operation start routine of the mist sauna device.

  The routine for the first fixed period operation mode is started from S200 in FIG. 5 and proceeds to the next step. The next step of S200 is S300. S300 is a routine having the flowchart shown in FIG. The second spray operation start routine starts from S300, and the process proceeds to S301. In S301, whether or not the water temperature in the water conduit 8 is equal to or higher than a predetermined temperature (a temperature at which a person does not feel cold, for example, between 30 ° C and 45 ° C. In this embodiment, 45 ° C). Confirm. If the water temperature is lower than the predetermined temperature (if No), the process proceeds to S305 described later. If the water temperature is equal to or higher than the predetermined temperature (Yes), the process proceeds to S302. In S302, the three-way valve 3 is switched to the sprinkler 9 side, and the process proceeds to S303.

  In S303, the water supply valve 4 is opened, and the process proceeds to S304. At this point, water (hot water) in the water conduit 8 is guided to the water spray tube 9, passes through the water spray tube 9, is misted by the atomizing nozzle 11, and is sprayed into the sauna room 100. In S304, the process exits from the spray operation start routine 2 and proceeds to S201 in FIG.

  In S301, if the water temperature is lower than the predetermined temperature (if No), the process proceeds to S305. In S305, the heater 6 which is a heating means is energized, and the process proceeds to S306. In S306, the three-way valve 3 is switched to the drain pipe 10 side, and the process proceeds to S307. In S307, the water supply valve 4 is opened, and the process proceeds to S308. At this time, the water (hot water) in the water guide pipe 8 is guided to the drain pipe 10.

  If the water temperature is lower than the predetermined temperature (45 ° C. in the present embodiment) in S308 (if No), the process returns to S308. If the water temperature is equal to or higher than the predetermined temperature (Yes), the process proceeds to S309. In S309, the three-way valve 3 is switched to the water pipe 9 side, and the process proceeds to S304. At this point, water (hot water) in the water conduit 8 is guided to the water spray tube 9, passes through the water spray tube 9, is misted by the atomizing nozzle 11, and is sprayed into the sauna room 100. In S304, the process exits from the spray operation start routine 2 and proceeds to S201 in FIG.

  In S201, it is confirmed whether or not “elapsed operation time ≧ planned operation time−first operation time”. Here, the elapsed operation time is the time that has elapsed since the operation of the mist sauna device 1 was started in the first fixed period operation mode. The scheduled operation time is a certain period during which the mist sauna device 1 described above is operated. Further, the first operation time is the last predetermined time during which the mist containing metal ions is sprayed as described above.

  If “Elapsed operation time ≧ Scheduled operation time−First operation time” is not satisfied (if No), the process returns to S201, and S201 is repeated until it is satisfied. If “elapsed operation time ≧ planned operation time−first operation time” is satisfied (if Yes), the process proceeds to S202.

  In S202, energization of the silver electrodes 22a and 22b of the silver ion elution unit 2 is started. At this point, silver ions are added to the water (hot water) in the water spray tube 9, and silver ion water is generated. This silver ion water passes through the water spray tube 9, is misted by the atomizing nozzle 11, and is discharged into the sauna room 100. At this time, if the presence of a person is confirmed by the human sensor 13, the control unit 7 drives a drive motor (not shown) to direct the atomizing nozzle 11 in the direction in which the person exists. At this time, if the presence of a person is detected at a plurality of positions, the atomizing nozzle 11 is swung, or the direction of the atomizing nozzle 11 is sequentially set to each person's position at regular intervals (for example, every 30 seconds). Change it. At this time, if the presence of a person is not detected, the direction of the atomizing nozzle 11 may be changed, may not be changed, or may be swung. Until S202 is reached, the atomizing nozzle 11 may not be directed in the direction in which the person exists, or may be directed in the direction in which the person exists. Thereafter, the process proceeds to S203.

  In S203, it is confirmed whether or not “elapsed operation time ≧ planned operation time”. If “elapsed operation time ≧ scheduled operation time” is not satisfied (if No), the process returns to S203, and S203 is repeated until it is satisfied. If “elapsed operation time ≧ scheduled operation time” is satisfied (if Yes), the process proceeds to S204.

  In S204, the spraying operation is stopped, and the process proceeds to S205. That is, in S204, the control unit 7 performs an operation of closing the water supply valve 4, stopping the energization of the silver electrodes 22a and 22b, and stopping the spraying operation such as stopping the energization of the heater 6. In S205, the routine of the operation mode for the first fixed period is exited.

  In the first fixed period operation mode described above, for example, it is assumed that scheduled operation time = 60 minutes and first operation time = 15 minutes are set. In this case, mist containing no silver ions is sprayed until 45 minutes have elapsed from the start of operation of the mist sauna device 1, and mist containing silver ions is sprayed after 45 minutes have elapsed from the start of operation of the mist sauna device 1. The operation of the mist sauna apparatus 1 stops 60 minutes after the start of the operation of the mist sauna apparatus 1.

  By providing such an operation mode for the first fixed period, it is possible to reduce the possibility that the sauna will be consumed for a long time and the physical strength will be consumed. In addition, since the mist spraying operation of the mist sauna device 1 is automatically stopped after a certain period of time, it is possible to prevent the user from forgetting to stop the mist sauna device 1.

  In addition, when spraying mist containing silver ions (antibacterial metal ions) for a long time, the silver ions contained in the initially sprayed mist adhere to the inside of the sauna room 100 or the user's body surface. It flows from the inside of the sauna room 100 to a drain outlet, a drain ditch, etc. together with water and sweat. Therefore, although there is an effect of antibacterial drainage grooves and drainage openings, silver ions are wasted in terms of antibacterial action in the sauna room 100 and the user's body surface. However, by providing such an operation mode for the first certain period of time, silver ions can be effectively adhered to the inside of the sauna room 100 or the surface of the user's human body while suppressing the consumption of silver ions.

  As described above, the scheduled operation time and the first operation time may be fixed, but may be arbitrarily set by the user. In addition, the first operation time requires time for the mist of silver ion water (metal ion water having antibacterial properties) to reach the entire sauna room 100 or the human body surface. Since the time varies depending on various factors such as the amount of mist sprayed by the apparatus 1, it is preferably obtained experimentally.

  In addition, it can also be set as 1st driving | running time = driving | operation scheduled time. In this case, silver ion mist is sprayed from the start of operation of the mist sauna device 1.

  Thus, when switching the presence or absence of silver ion elution and performing the operation, as long as the silver ion elution unit 2 can select elution / non-elution of silver ions by the presence or absence of voltage application as described above, Easy to use.

  As another modification of the present embodiment, for example, until “elapsed operation time ≧ first predetermined time” is satisfied, mist that does not contain silver ions (metal ions having antibacterial properties) is sprayed. The mode which sprays the mist containing silver ion may be sufficient. However, the first predetermined time is shorter than the scheduled operation time. The first predetermined time may be fixed or may be set arbitrarily by the user. In this case, assuming that the first predetermined time = 15 minutes, 15 minutes have elapsed from the start of operation of the mist sauna device 1 regardless of whether the scheduled operation time is 60 minutes or 90 minutes. Until then, mist containing silver ions is sprayed, and after 15 minutes, mist containing silver ions is sprayed. And operation | movement of the mist sauna apparatus 1 stops after driving | operation estimated time progress.

  Alternatively, mist that does not contain silver ions (antibacterial metal ions) is sprayed until “elapsed operation time ≧ planned operation time × first predetermined rate” is satisfied, and if it is satisfied, mist that contains silver ions is sprayed. Mode may be used. In this case, the first predetermined rate is assumed to be between 0 and 1. The first predetermined rate may be fixed or may be arbitrarily set by the user. In this case, assuming that the scheduled operation time is 60 minutes and the first predetermined rate is 0.25, until 15 minutes (60 minutes × 0.25 = 15 minutes) have elapsed from the start of operation of the mist sauna device 1, A mist not containing silver ions is sprayed, and after 15 minutes, mist containing silver ions is sprayed. And operation | movement of the mist sauna apparatus 1 stops after 60 minutes progress.

  Next, another mist spray start operation of the mist sauna apparatus 1 which is a mist spray apparatus will be described as a third embodiment of the mist spray apparatus of the present invention and a room including the mist spray apparatus. In the third embodiment, parts that are the same as the parts described in the previous embodiments are given the same reference numerals, and descriptions thereof are omitted. In the third embodiment, the mist sauna device 1 has an operation mode for a second fixed period. In the second fixed period operation mode, for example, the mist sauna device 1 is operated only during a fixed period to spray mist. This is a mode in which the metal ion concentration of the metal ion water is made higher than the previous concentration and the mist is sprayed only during the second operation time). This fixed period (for example, 30 minutes, 60 minutes, etc.) and the second operation time (the last 15 minutes, the last 20 minutes, etc.), which is a predetermined time, may be fixed or can be arbitrarily determined by the user. Anyway. The relationship between the second operation time and the fixed period is “second operation time ≦ fixed period”.

  FIG. 7 is a flowchart showing a routine of a second fixed period operation mode of the mist sauna device.

  The routine for the second fixed period operation mode is started from S250 in FIG. 7 and proceeds to the next step. The next step of S250 is S100. Since S100 is a routine having the flowchart shown in FIG. 4 described above, description thereof is omitted here. After exiting S100, the process proceeds to S251 in FIG.

  In S251, it is confirmed whether or not “elapsed operation time ≧ planned operation time−second operation time”. Here, the elapsed operation time is the time that has elapsed since the operation of the mist sauna device 1 was started in the second fixed period operation mode. The scheduled operation time is a certain period during which the mist sauna device 1 described above is operated. Furthermore, the second operation time is the last predetermined time for spraying the mist having a higher concentration than the previous concentration as described above.

  If “elapsed operation time ≧ scheduled operation time−second operation time” is not satisfied (if No), the process returns to S251 and repeats S251 until it is satisfied. If “elapsed operation time ≧ planned operation time−second operation time” is satisfied (if Yes), the process proceeds to S252.

  In S252, by increasing the energization amount to the silver electrodes 22a and 22b of the silver ion elution unit 2, the elution amount of silver ions is increased, and the process proceeds to S253. At this time, the amount of silver ions added to the water (hot water) in the sprinkler tube 9 increases, and silver ion water having a higher concentration than the silver ion water before the second operation time elapses is generated. Is done. This silver ion water passes through the water spray tube 9, is misted by the atomizing nozzle 11, and is discharged into the sauna room 100.

  In S253, it is confirmed whether or not “elapsed operation time ≧ planned operation time”. If “elapsed operation time ≧ scheduled operation time” is not satisfied (if No), the process returns to S253, and S253 is repeated until it is satisfied. If “elapsed operation time ≧ scheduled operation time” is satisfied (if Yes), the process proceeds to S254.

  In S254, the spraying operation is stopped, and the process proceeds to S255. That is, in S254, the control unit 7 performs an operation of closing the water supply valve 4, stopping the energization of the silver electrodes 22a and 22b, and stopping the spraying operation such as stopping the energization of the heater 6. In S255, the routine of the operation mode for the second fixed period is exited.

  In the above-described second fixed period operation mode, for example, it is assumed that scheduled operation time = 60 minutes and second operation time = 15 minutes are set. In this case, for example, silver ion water mist with a concentration of 90 ppb is sprayed until 45 minutes have elapsed from the start of operation of the mist sauna device 1, and silver ions with a concentration of 600 ppb are passed after 45 minutes have elapsed from the start of operation of the mist sauna device 1. Water mist is sprayed, and the operation of the mist sauna apparatus 1 stops 60 minutes after the start of the operation of the mist sauna apparatus 1.

  By providing such a second fixed period operation mode, it is possible to reduce the possibility that the sauna will be consumed excessively for a long time, as in the first fixed period operation mode described above. In addition, since the mist spraying operation of the mist sauna device 1 is automatically stopped after a certain period of time, it is possible to prevent the user from forgetting to stop the mist sauna device 1.

  In addition, when spraying mist containing silver ions (antibacterial metal ions) for a long time, the silver ions contained in the initially sprayed mist adhere to the inside of the sauna room 100 or the user's body surface. It flows from the inside of the sauna room 100 to a drain outlet, a drain ditch, etc. together with water and sweat. Therefore, although there is an effect of antibacterial drainage grooves and drainage openings, silver ions are wasted in terms of antibacterial action in the sauna room 100 and the user's body surface. However, by providing such an operation mode for the second fixed period, the silver ion water mist having a high concentration is finally sprayed, so that the consumption of silver ions is suppressed and the inside of the sauna room 100 or the surface of the user's human body. Silver ions can be effectively adhered to the surface.

  As described above, the scheduled operation time and the second operation time may be fixed, but may be arbitrarily set by the user. In addition, the second operation time requires time for mist of high-concentration silver ion water (metal ion water having antibacterial properties) to reach the entire sauna room 100 and the human body surface. Since the time varies depending on various factors such as the amount of mist sprayed by the mist sauna apparatus 1 and the amount of mist, it is preferable to obtain experimentally. Moreover, the silver ion water concentration sprayed during the second operation time and the silver ion water concentration during other periods may be arbitrarily set by the user.

  In addition, it can also be set as 1st driving | running time = driving | operation scheduled time. In this case, high-concentration silver ion mist is sprayed from the start of operation of the mist sauna apparatus 1.

  As described above, when performing the operation of switching the concentration of silver ion elution, the silver ion elution unit 2 can be used as long as it can select elution / non-elution of silver ions with or without voltage application. Is good.

  As another modification of the present embodiment, for example, a low concentration (for example, 90 ppb) silver ion water (antibacterial metal ion water) mist is used until “elapsed operation time ≧ second predetermined time” is satisfied. If sprayed and established, a mode in which silver ion water mist with a high concentration (for example, 600 ppb) is sprayed may be used. However, the second predetermined time is shorter than the scheduled operation time. The second predetermined time may be fixed or may be arbitrarily set by the user. In this case, assuming that the second predetermined time is 15 minutes, 15 minutes have elapsed from the start of operation of the mist sauna device 1 regardless of whether the scheduled operation time is 60 minutes or 90 minutes. Until then, a low concentration (for example, 90 ppb) silver ion water mist is sprayed, and after 15 minutes, a high concentration (for example, 600 ppb) silver ion water mist is sprayed. And operation | movement of the mist sauna apparatus 1 stops after driving | operation estimated time progress.

  Alternatively, until “elapsed operation time ≧ operation scheduled time × second predetermined rate” is satisfied, spraying low-concentration (for example, 90 ppb) silver ion water (antibacterial metal ion water) mist, A mode in which silver ion water mist with a high concentration (for example, 600 ppb) is sprayed may be used. In this case, the second predetermined rate is assumed to be between 0 and 1. The second predetermined rate may be fixed or may be arbitrarily set by the user. In this case, assuming that the scheduled operation time is 60 minutes and the first predetermined rate is 0.25, until 15 minutes (60 minutes × 0.25 = 15 minutes) have elapsed from the start of operation of the mist sauna device 1, A low concentration (for example, 90 ppb) silver ion water mist is sprayed, and after 15 minutes, a high concentration (for example, 600 ppb) silver ion water mist is sprayed. And operation | movement of the mist sauna apparatus 1 stops after 60 minutes progress.

  A mist spraying apparatus according to a fourth embodiment of the present invention and a room including the mist spraying apparatus will be described with reference to FIG. FIG. 8: is a schematic perspective view of 4th Embodiment of the room provided with the mist spraying apparatus of this invention. In the fourth embodiment, a mist sauna device is used as a mist spraying device, and a sauna room is used as an example. As shown in FIG. 8, the sauna room 100 includes a ventilation fan 14 as a ventilation means, a drying device 15 as a drying means, and a clothes bar 16 as a suspension means. In the fourth embodiment, parts that are the same as the parts described in the previous embodiments are given the same reference numerals, and descriptions thereof are omitted.

  FIG. 9 is a schematic sectional view of the ventilation fan 14. The ventilation fan 14 includes a housing 14a, a filter 14b, a propeller fan 14c, a louver 14d, and the like. The propeller fan 14c is connected to a fan motor (not shown) and is rotatable. The ventilation fan 14 is installed on the wall surface 12 as shown in FIGS. When the fan motor rotates, the propeller fan 14c also rotates, and the air in the sauna room 100 passes through the filter 14b and is discharged to the outside from the louver 14d. Also, outdoor air can be drawn into the sauna room 100 by reversing the direction of rotation of the fan motor.

  FIG. 10 is a schematic cross-sectional view of the drying device 15. The drying device 15 includes a housing 15a, a filter 15b, a sirocco fan 15c, a louver 15d, a heat exchanger 15e, and the like. The sirocco fan 15c is connected to a fan motor (not shown) and is rotatable. The heat exchanger 15e is a known one used in air conditioners and the like, and hot water flows through the piping. As shown in FIGS. 8 and 10, the drying device 15 is installed on the wall surface 12 (the wall surface on the top surface side). When the fan motor rotates, the sirocco fan 15c also rotates, and the air in the sauna room 100 passes through the filter 15b and reaches the heat exchanger 15e via the sirocco fan 15c. In the heat exchanger 15e, the air is warmed, blown out as warm air in the direction in which the louver 15d is directed, and returned to the sauna room 100 again. Note that if only the sirocco fan 15c is rotated without flowing hot water through the piping of the heat exchanger 15e, it can also be used as a blower.

  Further, the mist sauna device 1 and the ventilation fan 14, and the mist sauna device 1 and the drying device 15 are connected by a communication cable (not shown) and can communicate with each other. The ventilating fan 14 and the drying device 15 are controlled to start and stop operation by the control unit 7 of the mist sauna device 1.

  Then, the operation | movement with ventilation of the mist sauna apparatus 1 is demonstrated. FIG. 11 is a flowchart showing a routine of the operation mode with ventilation. The operation mode with ventilation is started from S400, and the process proceeds to S100.

  Since this S100 is the first spray operation start routine shown in FIG. 4, a detailed description thereof will be omitted. When the process exits the first spray operation start routine of S100, the process proceeds to S401.

  In S401, it is confirmed whether or not “elapsed operation time ≧ mist spray operation time”. Here, the elapsed operation time is the time that has elapsed since the operation of the mist sauna device 1 was started in the operation mode with ventilation. The mist spray operation time is a scheduled time for the mist sauna device 1 to perform the mist spray operation. This mist spraying operation time may be fixed or may be arbitrarily set by the user. At this stage, silver ion water mist is sprayed into the sauna room 100, so that silver is applied to the surface of the human body, the wall surface in the sauna room 100, the drainage groove, the drainage port, the basin in the sauna room 100, and the like. Adhere ionic water.

  If “elapsed operation time ≧ mist spray operation time” is not satisfied (if No), the process returns to S401 and repeats S401 until it is satisfied. If “elapsed operation time ≧ mist spray operation time” is established (Yes), the process proceeds to S402.

  In S402, the spraying operation is stopped, and the process proceeds to S403. That is, in S402, the water supply valve 4 is closed, the energization to the silver electrodes 22a and 22b is stopped, and the spraying operation such as the energization to the heater 6 is stopped.

  In S403, the operation of the ventilation fan 14 is started. That is, a fan motor (not shown) is energized, and the propeller fan 14c is rotated to discharge the air in the sauna room 100 and the remaining mist to the outdoors. Thereby, the silver ion water adhering to the human body surface of the person in the sauna room 100 can be dried. Next, the process proceeds to S404.

  In S404, it is confirmed whether or not “elapsed ventilation operation time ≧ ventilation operation operation time”. Here, the ventilation elapsed operation time is the time elapsed since the ventilation operation of the ventilation fan 14 was started in the operation mode with ventilation. The ventilation operation operation time is a scheduled time for the ventilation fan 14 to ventilate. This ventilation operation operation time may be fixed or may be arbitrarily set by the user.

  If “ventilation elapsed operation time ≧ ventilation operation operation time” is not satisfied (if No), the process returns to S404, and S404 is repeated until it is satisfied. If “ventilation elapsed operation time ≧ ventilation operation operation time” is satisfied (Yes), the process proceeds to S405.

  In S405, the operation of the ventilation fan 14 is stopped, and the process proceeds to S406. In S406, the routine of the operation mode with ventilation is exited.

  In the above-described operation mode with ventilation, for example, it is assumed that mist spray operation time = 30 minutes and ventilation operation operation time = 180 minutes are set. In this case, the mist sauna device 1 sprays mist containing silver ions for 30 minutes from the start of operation, and stops the mist spraying after 30 minutes. Subsequently, the ventilation fan 14 is turned to start ventilation. At this time, counting of the ventilation elapsed operation time starts. Then, until the ventilation elapsed operation time has passed 180 minutes, the ventilation fan 14 is rotated to continue ventilation, and when the ventilation elapsed operation time has passed 180 minutes, the ventilation fan 14 stops.

  By performing the operation mode with ventilation as described above, mist containing silver ions, which are metal ions having antibacterial properties, is sprayed into the sauna room 100, and silver ion water or sauna room adhered to the human body surface by ventilation. The silver ion water that has spread throughout 100 becomes easy to dry. When silver ion water adhering to the surface of the human body or the wall surface 12 in the sauna room 100 is dried, silver ions (metal ions having antibacterial properties) are not volatilized like hypochlorite ions, and silver compounds. It remains as (metal compound). The silver compound (metal compound) remaining in such a form is easily dissolved because it is minute, and when it comes into contact with moisture (for example, sweat or condensation), it becomes silver ions (metal ions) and exhibits an antibacterial effect.

  In this manner, the surface of the human body and the inside of the sauna room 100 can be subjected to antibacterial treatment. Silver ion mist is also effective when the inside of the sauna room 100 cannot be completely dried by ventilation operation. In fact, even if the ventilation operation is carried out, there are many basins and chairs in the sauna room 100, and it is difficult to dry the shadowed parts and the parts underneath. There is a part. In addition, water always accumulates at drain outlets, and it is extremely difficult to dry. In those parts, slime, odor, and mold may occur, which may cause discomfort to the user.

  In the case of a sterilization / antibacterial method using an ultraviolet lamp, it is difficult and ineffective to irradiate ultraviolet rays on a shadowed part such as a basin or a chair or a part where water such as a drain outlet is always accumulated. However, in the case of silver ion mist, it wraps around the shaded part in the form of mist or flows into the drain outlet or drain groove as silver ion water, so that it is easy to obtain a sterilizing / antibacterial effect. Moreover, when the water in the silver ion mist is partially dried, the silver ion concentration in the mist is increased. When the silver ion concentration is increased, the antibacterial effect is enhanced as shown in Table 2 described above, so that slime, odor, and mold can be more effectively prevented. As described above, before the drying or ventilation, the silver ion mist (metal ion mist) is sprayed, so that the antibacterial treatment in the sauna room 100 can be performed to prevent slime and the like.

  As described above, the mist spraying operation time and the ventilation operation operation time may be fixed, but may be arbitrarily set by the user. The mist spraying operation time requires time for silver ions (antibacterial metal ions) to reach the human body surface or the entire sauna room 100. The inner volume of the sauna room 100, the amount of mist sprayed, etc. Since the time varies depending on various factors, it is preferably obtained experimentally.

  As another modification of the present embodiment, the human body surface or the inside of the sauna room 100 may be dried by the drying device 15 instead of the ventilation fan 14. In this case, drying is performed according to the flowchart showing the routine of the operation mode with drying shown in FIG.

  Since S500 to S502 are the same operations as S400 to S402 in the flowchart showing the routine of the operation mode with ventilation shown in FIG.

  In S503, the operation of the drying device 15 is started. That is, energization of a fan motor (not shown) is performed, the sirocco fan 15c is rotated, the air in the sauna room 100 is sucked, the temperature is raised by the heat exchanger 15e, and then again in the sauna room 100 Blow out as warm air. Thereby, the silver ion water adhering to the human body surface of the person in the sauna room 100 can be dried. Next, the process proceeds to S504.

  In S504, it is confirmed whether or not “dry elapsed operation time ≧ dry operation operation time”. Here, the dry elapsed operation time is the time that has elapsed since the drying operation of the drying device 15 was started in the operation mode with drying. The drying operation operation time is a scheduled time for the drying device 15 to perform the drying operation. The drying operation operation time may be fixed or may be arbitrarily set by the user.

  If “dry elapsed operation time ≧ dry operation operation time” is not satisfied (if No), the process returns to S504 and repeats S504 until it is satisfied. If “dry elapsed operation time ≧ dry operation operation time” is satisfied (if Yes), the process proceeds to S505.

  In S505, the operation of the drying device 15 is stopped, and the process proceeds to S506. In step S506, the routine of the operation mode with drying is exited.

  In the operation mode with drying described above, for example, it is assumed that the mist spray operation time = 30 minutes and the drying operation operation time = 60 minutes are set. In this case, the mist sauna device 1 sprays mist containing silver ions for 30 minutes from the start of operation, and stops the mist spraying after 30 minutes. Subsequently, the drying device 15 is operated to start drying. At this time, the counting of the elapsed dry operation time starts. Then, the drying device 15 is operated to continue drying until the elapsed drying operation time has passed 60 minutes, and when the elapsed drying operation time has passed 60 minutes, the drying device 15 stops.

  By performing the operation mode with drying as described above, mist containing silver ions, which are metal ions having antibacterial properties, is sprayed into the sauna room 100 and also on the human body surface by the hot air blown from the drying device 15. The adhered silver ion water and the silver ion water that has spread throughout the sauna room 100 are easily dried. When silver ion water adhering to the surface of the human body or the wall surface 12 in the sauna room 100 is dried, silver ions (metal ions having antibacterial properties) are not volatilized like hypochlorite ions, and silver compounds. It remains as (metal compound). The silver compound (metal compound) remaining in such a form is easily dissolved because it is minute, and when it comes into contact with moisture (for example, sweat or condensation), it becomes silver ions (metal ions) and exhibits an antibacterial effect.

  In addition, when the drying operation is performed by raising the temperature in the sauna room 100 with warm air, the temperature in the sauna room 100 is lowered after the drying operation is completed, and condensation occurs on the wall surface 12 in the sauna room 100 or the like. In some cases, this dew condensation becomes silver ions again and exhibits antibacterial effects.

  Moreover, since the sauna room 100 is provided with the clothes-drying rod 16, the sauna room 100 can also be used as a drying room by operating the drying device 15 by hanging clothes on the clothes-drying bar 16 after washing. It becomes possible.

  Further, mist containing silver ions, which are metal ions having antibacterial properties, is sprayed from the mist sauna device 1 in a state where clothes (underwear, shirts, etc.) or towels are hung on the clothes bar 16. By doing so, silver ion mist adheres to clothes etc. Then, the silver ion water adhering to clothes etc. is dried by ventilating with the ventilation fan 14, and drying with the drying apparatus 15. FIG.

  When it takes time to dry the clothes after washing, the bacteria may propagate and give off an unpleasant odor, but the antibacterial effect of the attached silver ions can prevent the generation of the odor. Moreover, when the silver ion mist adhering to clothing dries, the silver ions do not volatilize like hypochlorite ions and remain as silver compounds. The silver compound remaining in such a form is fine and easily dissolved, and becomes silver ions when exposed to moisture (for example, sweat or raindrops), thereby exhibiting an antibacterial effect.

  In addition to clothing, mats, suits, and other items that are difficult to wash can be treated with silver ion mist.

  Moreover, in the said embodiment, although it was the mode which operates the ventilation fan 14 which is a ventilation means, and the drying apparatus 15 which is a drying means separately, it is a mode which uses the ventilation fan 14 and the drying apparatus 15 together. Also good. For example, after the operation of the mist sauna device 1 is completed, the mist and water vapor remaining in the sauna room 100 may be discharged to the outdoors by the ventilation fan 14 and then dried by the drying device 15.

  The drying means may use an air conditioner instead of the drying device 15 that blows warm air using the hot water described above. When an air conditioner is used, dehumidification and heating can be performed, so that the surface of a human body, a room, laundry, and the like can be more efficiently dried.

  Moreover, in the said embodiment, although the ventilation means and the drying means are provided in the different body, they may be integrated. Furthermore, it is good also as a structure which integrates a mist spraying apparatus and a drying means, detects the direction where the human body exists also for the warm air by a drying means, and blows out toward the direction where a human body exists.

  The above embodiment is merely an example, and the specific configuration of the mist spraying apparatus, the specific shape and configuration of the silver ion elution unit and the metal electrode (silver electrode), the mounting position, etc. are also exemplified in all respects. However, it should be considered not restrictive. The scope of the present invention is shown not by the above embodiments but by the scope of claims, and includes all modifications and variations within the meaning and scope equivalent to the scope of claims.
