Description

  The present invention relates to a liquid refinement unit, a liquid refinement apparatus, and a sauna apparatus using the same.

  For example, the configuration of a liquid micronizer used for a sauna device has the following configuration.

  That is, a main body case having an air supply port and an exhaust port, a blower means provided in an air passage in the main body case, and a liquid refinement means provided between the blower means and the exhaust port, the liquid refinement The means is configured to supply liquid to the upper surface of the rotating disk and to finely disperse the liquid thinly spread on the disk outward by centrifugal force (see, for example, Patent Document 1).

JP-A-4-11068

  The problem with the above conventional example is that the efficiency of liquid miniaturization is low.

  That is, as described above, the conventional liquid miniaturization apparatus finely divides the liquid from the upper surface of the disk by centrifugal force. However, it is sufficient to scatter the liquid outward from the disk. The liquid is scattered without being miniaturized, and the efficiency of miniaturization is lowered.

  Therefore, in order to solve this problem, a method has been proposed in which a cylinder is provided on the outer periphery of the rotating plate and the liquid splashed from the rotating plate is collided to promote liquid miniaturization. Even if it is made to collide with the inner wall of the cylinder, the collision energy cannot be effectively utilized if it simply collides with the inner surface of the cylinder, and miniaturization is not sufficiently promoted. In other words, in this case, since the scattered liquid collides with the inner surface of the cylinder in a direction inclined with respect to the inner surface, the collision energy cannot be utilized for crushing, and as a result, the liquid refinement efficiency is improved. It would be low.

  Therefore, the present invention aims to improve the efficiency of liquid miniaturization.

In order to achieve this object, the present invention includes a cylindrical outer shell, a rotating shaft disposed in the outer shell in the vertical direction, and a plurality of shafts fixed at predetermined intervals in the axial direction of the rotating shaft. A rotary plate, a liquid supply unit that supplies liquid to the upper surface of the upper rotary plate, and a liquid resupply unit that guides the liquid in the outer shell to the upper surface of the lower rotary plate, and the inner wall of the outer shell A plurality of projecting portions projecting toward the rotation shaft are provided, and the plurality of projecting portions have a collision in which a surface facing the rotation direction of the plurality of rotating plates is substantially orthogonal to a tangential direction of the plurality of rotating plates. The liquid resupply part has a water storage part provided in an annular shape on the inner wall of the cylindrical outer shell, and the plurality of protrusions protrude in the direction of the rotation axis from the water storage part. It is set as the structure and the said objective is achieved by this.

  As described above, the present invention includes a cylindrical outer shell disposed in the vertical direction, a rotary shaft disposed in the outer shell in the vertical direction, and a plurality of shafts fixed at predetermined intervals in the axial direction of the rotary shaft. An inner wall of the outer shell, a liquid supply unit that supplies liquid to the upper surface of the upper rotating plate, and a liquid resupply unit that guides the liquid in the outer shell to the upper surface of the lower rotating plate. Provided with a plurality of projecting portions projecting toward the rotating shaft, the surfaces of the projecting portions facing the rotational direction of the plurality of rotating plates being substantially orthogonal to a tangential direction of the plurality of rotating plates. By configuring the collision surface, the efficiency of liquid miniaturization can be improved.

  That is, in the present invention, the liquid splashed from the outer edges of the plurality of rotating plates due to the centrifugal force is scattered in the substantially tangential direction of the rotating plates and collides with the collision surface of the protruding portion at a substantially right angle. Therefore, the liquid droplets diffused by the collision are crushed and the miniaturization is promoted. As a result, the efficiency of the liquid miniaturization is improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Hereinafter, the case where the liquid is water will be described as an example.

(Embodiment 1)
FIG. 1 is a perspective view showing a liquid miniaturization unit 1 of the present invention.

  As shown in FIG. 1, the water refinement unit 1 includes a cylindrical outer shell 2 arranged in the vertical direction, a rotary shaft 3 arranged in the outer shell 2 in the vertical direction, and the rotational shaft 3. A plurality of rotating plates 4a and 4b fixed at predetermined intervals in the axial direction and a liquid supply unit 5 for supplying a liquid to the upper surface of the upper rotating plate 4a are provided. Although the outer shell 2 is cylindrical in the present embodiment, it is not always necessary to be a cylinder, and may be a cylinder having another shape.

  The upper end of the rotating shaft 3 is connected to a driving motor 6 provided on the upper portion of the outer shell 2, and the rotating shaft 3 extends in the vertical direction toward the lower surface of the outer shell 2, and a holding portion (see FIG. Not shown).

  The rotary plates 4a and 4b are formed in a flat plate shape with a hydrophilic resin, and the liquid supply unit 5 is configured to supply water near the center of the upper surface of the upper rotary plate 4a.

  The inner wall of the cylindrical outer shell 2 is provided with a plurality of projecting portions 7a projecting toward the rotating shaft 3 on the outer periphery of the rotating plate 4a, and a plurality of projecting portions projecting toward the rotating shaft 3 on the outer periphery of the rotating plate 4b. The protrusion 7b is provided. The shape of the plurality of protrusions 7a and 7b will be described later.

  The inner wall of the cylindrical outer shell 2 is further provided with a liquid resupply portion for recovering water from the outer shell 2 and guiding it to the lower rotating plate 4b between the upper rotating plate 4a and the lower rotating plate 4b. The water storage part 8 and the water channel 9 are provided.

  The water reservoir 8 is annularly formed along the inner wall of the cylindrical outer shell 2 between the upper rotating plate 4a and the lower rotating plate 4b, that is, between the plurality of protruding portions 7a and the plurality of protruding portions 7b. The water channel 9 for guiding water from the water storage section 8 to the upper surface of the lower rotating plate 4b is provided. In the present embodiment, the water channel 9 is configured to extend from the three sides of the water storage portion 8 toward the rotating shaft 3 and is configured to open on the lower rotating plate 4b.

  The cylindrical outer shell 2 has an opening 10a provided below for ventilating air and an opening 10b provided above, and the ventilation path 11 in the gap between the plurality of rotating plates 4a, 4b and the outer shell 2 is provided. It shall be configured to ventilate. In the present embodiment, as shown in FIGS. 1 and 2, the ventilation path 11 causes air sent from an air blowing means (not shown) installed outside to upward from the lower opening 10a to the upper opening 10b. It is configured to allow ventilation.

  Next, the shapes of the plurality of protrusions 7a and 7b will be described with reference to FIGS. 3 (a) and 3 (b).

  Since the plurality of protrusions 7a and the plurality of protrusions 7b have the same shape, only the plurality of protrusions 7a will be described here, and the description of the plurality of protrusions 7b will be simplified.

  As shown in FIG. 3A, the plurality of protrusions 7a are provided on the inner wall of the cylindrical outer shell 2 along the outer periphery of the rotating plate 4a, and the direction of the rotary shaft 3 from the inner wall of the cylindrical outer shell 2 It is configured to protrude. At this time, the inner wall of the outer shell 2 is formed so as to protrude inward so that the inner diameter of the cylindrical outer shell 2 provided with the plurality of protrusions 7a and the inner diameter of the water storage portion 8 provided in an annular shape are substantially equal. The plurality of protruding portions 7 a are configured to protrude in the direction of the rotation shaft 3 from the inner periphery of the water storage portion 8. Thereby, when the air is ventilated through the ventilation path 11 in the gap between the rotating plate 4a and the outer shell 2, the surfaces of the plurality of protrusions 7a and the inner wall of the outer shell 2 come into contact with the air passing through the ventilation path 11. It is said.

  As shown in FIG. 3 (b), the plurality of projecting portions 7a are intermittently arranged at substantially equal intervals along the outer periphery of the rotating plate 4a, and the rotation direction of the rotating plate 4a of the plurality of projecting portions 7a. The surface that faces the surface constitutes a collision surface 13 that is substantially orthogonal to the tangent 12 of the rotating plate 4a.

  Next, the operation of the above configuration will be described.

  In the liquid micronization unit 1 shown in FIG. 1, when the motor 6 is driven, the rotary shaft 3 rotates at high speed inside the cylindrical outer shell 2, and the rotary plates 4a and 4b are rotated at high speed accordingly.

  At this time, the liquid supply unit 5 supplies water to the vicinity of the center of the upper surface of the rotating plate 4a that rotates at a high speed. The water supplied to the upper surface of the rotating plate 4a spreads in the form of a thin film from the vicinity of the center of the rotating plate 4a toward the outer periphery due to the centrifugal force caused by the high-speed rotation. Are blown away at high speed in the direction of the tangent line 12 shown in FIG.

  And most of the water droplets scattered at high speed from the outer edge of the rotating plate 4a due to the centrifugal force are scattered in substantially the same direction as the tangent 12 of the rotating plate 4a, and the scattered water droplets collide with the collision surfaces 13 of the plurality of projecting portions 7a. Therefore, the dispersed droplets are effectively crushed by the collision, and miniaturization is promoted.

  Further, the water droplets collided with the collision surface 13 are scattered in the space of the ventilation path 11 through the gap between the outer shell 2 and the plurality of protrusions 7a and the rotating plate 4a, and the rotating plate 4a rotating at high speed Then, it collides with the adjacent collision part 7 again and is crushed, and the refinement of water is further promoted.

  Thus, most of the water supplied from the liquid supply unit 5 to the upper surface of the upper rotating plate 4a is dissipated from the rotating plate 4a rotating at high speed, and collides with the collision surfaces 13 of the plurality of projecting portions 7a. At this time, most of the water is fined, and such fine water droplets are brought into contact with the air passing through the ventilation path 11 shown in FIG.

  On the other hand, among the water droplets scattered from the upper rotating plate 4a by centrifugal force, few water droplets adhered to the surface of the plurality of protruding portions 7a and the inner wall of the outer shell 2 without being miniaturized, or condensed after being miniaturized. A small amount of water droplets flow down and collected in the water storage unit 8 shown in FIG. 2 and are carried to the upper surface of the lower rotating plate 4 b through the water channel 9.

  Thus, even a small amount of water carried to the lower rotating plate 4b is diffused in the direction of the tangent 12 of the rotating plate 4b shown in FIG. By colliding with the collision surfaces 13 of the plurality of protrusions 7b substantially at right angles, the water droplets are crushed and the miniaturization is promoted.

  That is, even a few water droplets supplied to the lower rotating plate 4b spread in a thin film shape toward the outer peripheral direction by centrifugal force due to high-speed rotation, and are blown off at high speed from the outer peripheral edge of the rotating plate 4b toward the tangential line 12. The blown water droplets collide with the plurality of projecting portions 7b in the same manner and are effectively crushed, thereby promoting the miniaturization of water.

  Most of the water supplied to the upper surface of the lower rotating plate 4b is refined at this time, and is brought into contact with the air passing through the ventilation path 11 and conveyed in a refined state.

  According to the configuration and operation as described above, the supplied water spreads on the surfaces of the plurality of rotating plates 4a and 4b, and is dissipated from the outer edges of the rotating plates 4a and 4b by the centrifugal force of high-speed rotation and is only refined. In addition, water droplets scattered in the tangential direction from the outer edges of the rotating plates 4a and 4b are formed on the collision surfaces 13 of the plurality of projecting portions 7a and 7b provided along the inner wall of the outer shell 2 on the outer peripheral side of the rotating plates 4a and 4b. Since collision will occur at a substantially right angle, and the micronization of water will be effectively promoted by this collision, according to this embodiment, it is possible to provide the liquid micronization unit 1 that improves the micronization efficiency. It becomes possible.

  In addition, since several protrusion part 7a, 7b protrudes in the space of the ventilation path 11 rather than the water storage part 8, the fine water droplet crushed by the collision surface 13 contacts with the air which passes through the inside of the ventilation path 11. As a result, it becomes difficult for water droplets to adhere to the surfaces of the protrusions 7a and 7b and the outer shell 2, and it becomes possible to efficiently perform crushing by collision, and fine water droplets adhere to the wall surface and cause condensation. Therefore, the water can be transported to the outside while maintaining the fine state of the water, and the fineness efficiency of the supplied water can be improved.

  As another form of the plurality of protrusions 7a and 7b, as shown in FIGS. 4 (a) and 4 (b), the inner diameter of the outer shell 2 is formed to be larger than the inner diameter of the water storage part 8, and the plurality of protrusions 7a and 7b project from the inner periphery of the water storage part 8 in the direction of the rotary shaft 3, it is possible to secure a wide ventilation space of the ventilation path 11 around the plurality of projections 7a and 7b. It is possible to secure a large area of the surface 13 and improve the water micronization efficiency, and moreover, the space in which the micronized water droplets colliding with the collision surface 13 can be scattered becomes wider. It becomes easy to mix with the air to be made, and it becomes possible to transport the micronized water droplets to the outside more efficiently. As a result, the micronization efficiency of the supplied water can be improved. Furthermore, since the water droplets scattered from the upper rotating plate 4a and adhering to the plurality of protruding portions 7a are likely to flow down to the water storage portion 8 below the plurality of protruding portions 7a, the water droplets that could not be miniaturized can be efficiently removed. It can be recovered and refined again, and the refinement efficiency of the supplied water is further improved.

(Embodiment 2)
Embodiment 2 of the present invention will be described below with reference to the drawings.

  In the second embodiment, the details of the liquid miniaturization apparatus using the liquid miniaturization unit 1 of the first embodiment can be utilized particularly by using this unit for water miniaturization. This will be described in the embodiment of the apparatus.

  In addition, about the structure same as the structure of Embodiment 1, the same code | symbol is referred and the description is simplified.

  As shown in FIG. 5, a liquid micronizer 16 is attached to the ceiling surface 15 of the sauna room 14.

  As shown in FIGS. 6 to 8, the water refiner 16 includes a main body case 19 having a suction port 17 and an exhaust port 18 on a lower surface, and a suction port 17 and an exhaust port 18 in the main body case 19. A heat exchanger 20 as a heating means provided in a connecting air passage and fans 21a and 21b as air blowing means are provided, and the liquid miniaturization unit 1 described in FIG. 1 is built in between the fan 21a and the exhaust port 18. It is configured.

  The fans 21a and 21b are provided with casings 22a and 22b that open above the heat exchanger 20, respectively.

  As shown in FIG. 8, the outlet of the casing 22a of the fan 21a is configured to communicate with an opening 10a provided below the outer shell 2 of the liquid micronization unit 1. The opening 10 b above the outer shell 2 is configured to communicate with the exhaust port 18 via the junction 23. On the other hand, the air path from the outlet of the casing 22b of the fan 21b communicates with the exhaust port 18 through the junction 23 without passing through the liquid refinement unit 1 as shown in FIG. That is, the air blown from the fan 21 a and the fan 21 b merges at the junction 23 and is discharged from the exhaust port 18 to the sauna chamber 14.

  In the above configuration, a process in which the liquid refinement apparatus 16 including the liquid refinement unit 1 of Embodiment 1 performs the operation of water refinement in the sauna apparatus of this embodiment will be described.

  When using a sauna in the sauna room 14 of FIG. 5, first, a heat exchanger 20 shown in FIG. 6 is supplied from a heat source such as a gas water heater or an electric water heater (not shown) through the pipe 24 shown in FIG. Is supplied with water (hot water). Moreover, a part of this water is supplied to the liquid supply part 5 shown in FIG. The amount of water supplied to the liquid supply unit 5 is very small, and is not discharged from the liquid supply unit 5 at this time.

  In this state, when the heat exchanger 20 is operated and the fan 21a in FIG. 6 and the fan 21b in FIG. 7 are driven, the fans 21a and 21b draw the air in the sauna chamber 14 in FIG. The air sucked and sucked is heated by the heat exchanger 20 of FIG. The heated air is sucked into the casings 22a and 22b by the fans 21a and 21b. The air heated by the heat exchanger 20 is heated to about 60 degrees Celsius at this point.

  The high-temperature air sucked into the casing 22a is sent to the inside of the outer shell 2 through the opening 10a provided below the outer shell 2 of the liquid micronization unit 1, and therefore the inside of the outer shell 2 is shown in FIGS. Ascending airflow is generated via the ventilation path 11 shown.

  At this time, when the motor 6 is driven, the rotating shaft 3 rotates at a high speed inside the outer shell 2, and the rotating plates 4a and 4b are rotated at a high speed accordingly. And the liquid supply part 5 supplies water to the center vicinity of the upper surface of the rotating plate 4a shown in FIG. The water supplied to the upper surface of the rotating plate 4a spreads in the form of a thin film from the vicinity of the center of the rotating plate 4a toward the outer periphery due to the centrifugal force caused by the high-speed rotation. Are blown away at high speed in the direction of the tangent line 12 shown in FIG.

  And most of the water droplets scattered at high speed from the outer edge of the rotating plate 4a due to the centrifugal force are scattered in substantially the same direction as the tangent 12 of the rotating plate 4a, and the scattered water droplets collide with the collision surfaces 13 of the plurality of projecting portions 7a. Therefore, the dispersed droplets are effectively crushed by the collision, and miniaturization is promoted.

  In this way, most of the water supplied from the liquid supply unit 5 to the upper surface of the upper rotating plate 4a is scattered at almost the same direction as the tangent 12 of the rotating plate 4a due to high-speed rotation, and is incident on the collision surface 13. Air that collides and is crushed and refined, and scatters in the space of the ventilation path 11 that passes through the gap between the outer shell 2 and the plurality of protrusions 7a and the rotating plate 4a, and passes through the ventilation path 11 That is, it is mixed with the warm air blown into the outer shell 2 through the opening 10a by the blowing means 21a, and is discharged from the outer shell 2 through the opening 10b in a fine state, via the junction 23. To the exhaust port 18.

  In this way, most of the water supplied from the liquid supply unit 5 to the upper surface of the upper rotating plate 4a is dissipated from the rotating plate 4a rotating at a high speed and collides with the collision surfaces 13 of the plurality of projecting portions 7a at a substantially right angle. At this point, most of the water is effectively miniaturized, and such fine water droplets are brought into contact with warm air passing through the ventilation path 11 shown in FIG.

  Further, among the water droplets scattered by centrifugal force from the upper rotating plate 4a, few water droplets adhered to the inner wall of the outer shell 2 and the surfaces of the plurality of projecting portions 7a without being miniaturized, or condensed after being miniaturized. Most of the slight water droplets are retained and dried as they are without flowing down from the inner wall by the warm updraft passing through the ventilation path 11 inside the outer shell 2.

  When a slight water droplet adhering to the inner wall of the outer shell 2 or the plurality of protrusions 7a is not retained by the rising airflow without being dried by the warm rising airflow passing through the ventilation path 11 in the outer shell 2, the water storage section It flows down to 8 and is stored. A small amount of water stored in the water storage section 8 is conveyed from the three directions of the water storage section 8 to the upper surface of the lower rotating plate 4b through the water channel 9.

  In this way, a small amount of water carried to the lower rotating plate 4b is also diffused in the direction of the tangent 12 of the rotating plate 4b by the centrifugal force of the high-speed rotation of the lower rotating plate 4b, similarly to the upper rotating plate 4a. Thus, by colliding with the collision surfaces 13 of the plurality of protrusions 7b at substantially right angles, the water droplets are effectively crushed and the miniaturization is promoted. Further, the small water droplets that are effectively crushed and made fine by the collision come into contact with the high-temperature dry air blown from the air blowing means 21b through the opening 10a, and the vaporization of the fine water droplets is promoted to warm humidification. It becomes air and goes up the ventilation path 11.

  That is, even a few water droplets supplied to the lower rotating plate 4b spread in a thin film shape toward the outer peripheral direction by centrifugal force due to high-speed rotation, and are blown off at high speed from the outer peripheral edge of the rotating plate 4b toward the tangential line 12. Since the blown-off fine water droplets collide with the plurality of projecting portions 7b and are effectively crushed, the water is promoted to be miniaturized almost completely and further through the lower opening 10a. In contact with the high-temperature dry air blown in the air, vaporization of the fine water droplets is promoted.

  As described above, the humidified air containing the fine water droplets effectively crushed on the rotary plates 4a and 4b and the collision surfaces 13 of the plurality of collision portions 7a and 7b inside the liquid micronization unit 1 is formed in the lower opening 10a. It is vaporized by mixing with high-temperature dry air introduced from above, or becomes warm humidified air containing fine water droplets, and is discharged to the junction 23 through the opening 10 b above the outer shell 2.

  On the other hand, since the high-temperature dry air sucked into the casing 22b by the fan 21b does not pass through the liquid refinement unit 1, there is no vaporization effect due to water refinement. It is done. Then, the humidified air containing fine water droplets conveyed through the liquid refinement unit 1 and the high-temperature dry air are mixed in the junction 23 and the ceiling surface 15 of the sauna room 14 via the exhaust port 18. Is supplied to the inside of the sauna room 14.

  When the sauna operation is interrupted or stopped, the rotation of the fans 21a and 21b, the rotation shaft 3 and the rotation plates 4a and 4b, and the water supply from the liquid supply unit 5 are stopped. At that time, the water supplied from the liquid supply unit 5 is dissipated by the high-speed rotation of the upper rotating plate 4a and the lower rotating plate 4b, and a plurality of projecting portions provided along the inner wall of the outer shell 2 Colliding with the collision surface 13 of 7a, 7b at a substantially right angle, the collision is effectively miniaturized almost entirely.

  According to the above configuration and operation, not only is the outer plate of the rotating plates 4a and 4b dissipated from the outer edges of the rotating plates 4a and 4b by the centrifugal force of high speed rotation, but also the outer plates of the rotating plates 4a and 4b are rotated. Water droplets scattered in the tangential 12 direction are collided at substantially right angles to the collision surfaces 13 of the plurality of collision portions 7a and 7b provided on the outer peripheral sides of the rotating plates 4a and 4b, and are effectively crushed. As a result, water can be effectively crushed and can be effectively mixed with heated air. Therefore, a sauna apparatus using the liquid refining device 16 with improved water refining efficiency is provided. It becomes possible to do.

  That is, as described in the first embodiment, since the plurality of projecting portions 7 a and 7 b project into the space of the ventilation path 11 rather than the water storage portion 8, fine water droplets that are effectively crushed on the collision surface 13. It becomes easy to come into contact with warm air passing through the inside of the ventilation path 11, and as a result, water drops are less likely to adhere to the surfaces of the plurality of projecting portions 7a, 7b and the outer shell 2, and crushing due to collision is effectively and efficiently performed. It is possible to prevent the water droplets from adhering to the wall surface and condensing, so that it can be transported to the outside while maintaining the fine water state. It is possible to improve the miniaturization efficiency and provide a high-performance sauna device.

  Furthermore, even if a slight amount of water droplets scattered from the upper rotating plate 4a and adhered to the plurality of protrusions 7a remain by raising warm air to the ventilation path 11 of the outer shell 2 of the liquid micronization unit 1, In the ventilation path 11 that rises from the lower opening 10a of the outer shell 2 to the upper opening 10b, it is possible to prevent a slight amount of non-fine water droplets from flowing downward, and to remain in the ventilation path 11 for drying. Therefore, it is not necessary to discharge the non-micronized water droplets specially, and even if liquid that is not micronized adheres to the collision surfaces 13 of the plurality of projecting parts 7a and 7b or hot water remains in the water storage part 8. These are dried by the residual heat of the air heated by the heat exchanger 20, and therefore do not need to be discharged from the liquid micronizer 16 to the outside. Thereby, piping construction for discharging non-fine water droplets can be eliminated, and as a result, the construction work can be simplified.

  As another form of the plurality of protrusions 7a, 7b, as shown in FIG. 4, the inner diameter of the outer shell 2 is formed larger than the inner diameter of the water storage part 8, and the plurality of protrusions 7a, 7b are the water storage part. If it is configured to protrude in the direction of the rotation shaft 3 from the inner periphery of 8, the area of the collision surface 13 can be secured widely, and the ventilation space of the ventilation path 11 through which warm air passes around the plurality of protrusions 7a and 7b is provided. Since it becomes possible to ensure widely, there exists an effect that the refinement | miniaturization efficiency of water can be improved further. That is, since the space where the finely crushed water droplets that have been effectively crushed can collide with the collision surface 13 becomes wider, it becomes easier to mix with warm air passing through the ventilation path 11, and more finely sized water droplets. Can be transported to the sauna room 14, and as a result, the refinement efficiency of the supplied water can be improved, sufficient humidified air can be provided, and the comfort of the sauna user can be enhanced. Play. Furthermore, even if a few water droplets adhere to the collision surfaces of the plurality of protrusions 7a and are retained even by a warm ascending current and are not dried, the water storage section 8 below the plurality of protrusions 7a can be easily collected. Therefore, it is possible to efficiently recover the water droplets that could not be refined and to refine them again, and to improve the refinement efficiency of the supplied water.

  As described above, the liquid micronization unit and the liquid micronization device of the present invention and the sauna device using the same can efficiently miniaturize the liquid, that is, the collision energy can be effectively utilized. it can.

  Therefore, for example, utilization to a sauna device, a humidifier, a cooling device, a spraying device, a cleaning device, a plant growing facility, and the like is expected. Moreover, it can be used not only for warm water but also for other liquid refining equipment such as oil and detergent.
