And a water supply pipe 4 as a liquid supply means for supplying water to the rotating means 14.

  The water supply pipe 4 is provided with a constant flow valve 15, a water supply valve 16 is provided upstream of the constant flow valve 15, and a water supply port 17 is provided most downstream of the water supply pipe 4. A check valve 18 is provided in the vicinity of the water supply port 17 to prevent water from flowing backward.

  Further, as shown in FIG. 3, in the liquid refining means 10, a portion where the main flow of the air blown from the fan motor 9 is ventilated is a ventilation portion 28 (shaded portion in FIG. 3), and a portion where the main flow is not vented is not The ventilation port 29 may be used, and the water supply port 17 may be provided in the non-ventilation unit 29.

  Further, as shown in FIG. 4, a windbreak wall 30 may be provided in the vicinity of the water supply port 17. The windbreak wall 30 includes a plate-like wall that surrounds the water supply port 17 and an opening for flowing water to the water storage section 26. The windbreak wall 30 is preferably formed integrally with the liquid refinement means case 13.

  In the present embodiment, the rotating means 14 includes a rotating shaft 19 arranged in the vertical direction and a plurality of rotating plates 20a and 20b that rotate about the rotating shaft 19 in the axial direction of the rotating shaft 19. It is configured to be fixed at a predetermined interval in the vertical direction.

  A rotating motor 21 for driving the rotating shaft 19 is provided at the upper part of the rotating means 14, and a pumping pipe 22 formed integrally with the rotating plate 20a and the rotating plate 20b is provided at the lower part of the rotating means 14 in the vertical direction. In preparation. The pumping pipe 22 has a substantially cylindrical shape whose opening diameter becomes narrower toward the bottom.

  As shown in FIG. 5, the pumping pipe 22 is provided with two horizontally long liquid scattering portions 24 that spout the pumped water by a centrifugal force by rotation at a place where the rotating plate 20 b and the pumping pipe 22 are connected, and water is supplied. The position of the liquid scattering part 24 is shifted in the circumferential direction so that the ejection direction is different.

  As shown in FIG. 2, a crushing portion 25 connected to the liquid refinement means case 13 is provided on the outer periphery of the rotation means 14.

  Further, as shown in FIG. 2, the lower part of the liquid refinement means case 13 has a water storage unit 26, so that the amount of water that cannot be pumped by the pumping pipe 22, that is, the water storage amount of the water storage unit 26 at the end of the micronization operation is reduced. The lower part of the liquid refinement means case 13 has, for example, an inverted trapezoidal shape (convex downward).

  Further, a thermistor 27 is provided in the water reservoir 26 as a water level detection means.

  Next, the configuration of the control means 31 will be described with reference to FIG.

  The control unit 31 includes a control unit 32, a remote controller 33 including a display unit and an operation switch (not shown), and a thermistor 27 as a water level detection unit.

  The control unit 32 includes a microcomputer (hereinafter referred to as a microcomputer, not shown). The microcomputer uses an operation signal from the remote controller 33 to drive the electric heater 8, the fan motor 9, the rotating motor 21 that drives the rotating shaft 19, and the water supply valve. 16 is controlled.

  Next, operations and effects of the above configuration will be described.

  First, a normal sauna operation will be described. The electric heater 8 and the fan motor 9 are operated by an operation signal from the remote controller 33, and the fan motor 9 sucks air in the sauna room 1 through the suction port 5, and the sucked air is heated by the electric heater 8. Is done. The heated air is sent by the fan motor 9 to the liquid refinement means case 13 via the fan casing 11.

  On the other hand, when the rotary motor 21 is driven, the rotary shaft 19 rotates at a high speed, and accordingly, the rotary plate 20a and the rotary plate 20b are rotated at a high speed.

  At this time, the water supply pipe 4 supplies water at a flow rate set by the constant flow valve 15 and stores the water in the water storage unit 26. At this time, the pumping pipe 22 is rotating above the water storage section 26, and when the amount of water stored in the water storage section 26 increases and the water surface approaches the lower end of the water pumping pipe 22, the water storage in the water storage section 26 is combined with the air on the water surface. And move upward along the inner wall of the pumping pipe 22.

  That is, the pumping pipe 22 has a substantially cylindrical shape whose opening diameter becomes narrower toward the bottom, so that a suction force works inside. For this reason, the water stored in the water storage section 26 is rolled up together with the air on the water surface, and moves upward along the inner wall of the pumping pipe 22.

  The water that has moved upward along the inner wall of the pumping pipe 22 is first ejected from the liquid scattering portion 24 by centrifugal force due to rotation, is transmitted to the rotating plate 20b, and is thinned toward the outer periphery by centrifugal force due to high-speed rotation. The water that has spread in the shape of a thin film is blown off at high speed from the outer peripheral edge of the rotating plate 20b in the tangential direction.

  Thus, the water droplets scattered by the centrifugal force collide with the inner wall of the liquid refinement means case 13 and are crushed, thereby promoting the refinement of water.

  Further, the water that has moved upward along the inner wall of the pumping pipe 22 and has not been ejected from the liquid scattering portion 24 further rises along the inner wall of the pumping pipe 22 and is thinned toward the outer periphery by centrifugal force due to high-speed rotation. The water that spreads in the form of a thin film is blown off at high speed from the outer peripheral edge of the rotating plate 20a in the tangential direction.

  In this way, the water droplets scattered by the centrifugal force collide with the inner wall of the crushing portion 25 and are crushed, thereby promoting the miniaturization of water.

  At this time, the water that moves upward along the inner wall of the pumping pipe 22 is substantially uniform over the entire inner wall rather than turning spirally and moving upward because the rotary motor 21 rotates at high speed. To move straight up.

  Thus, almost all of the water pumped by the pumping pipe 22 is refined and mixed with the heated warm air to form a steam state and discharged from the upper opening, but part of the water is not refined. Slight water droplets adhering to the inner wall of the liquid refinement means case 13 or a minute amount of water droplets dewed on the inner wall after being refined, flow down the water storage section 26 through the inner wall of the liquid refinement means case 13, and are stored. The

  On the other hand, warm air containing water refined by the high-speed rotation of the rotating plate 20 a and the rotating plate 20 b is supplied as steam from the exhaust port 6 to the inside of the sauna room 1 by blowing air from the fan motor 9.

  At this time, the amount of water supplied from the water supply pipe 4 becomes a problem in order for the water pumped up by the water supply pipe 22 to be almost completely refined. That is, the amount of water that can be refined is set by the micronization capability of the liquid micronization unit 10, which is determined by the shape of the rotation unit 14, the rotational speed of the rotary motor 21, and the like, and is, for example, 45 cc / min.

  On the other hand, since the constant flow valve 15 varies in flow rate depending on the water temperature and water pressure, a buffer function is provided for the amount of water stored in the water storage unit 26 and the amount of water pumped in the pump pipe 22. When supplied for more than min, the amount of refined water increases while increasing the initial buffer amount, and the amount of water supplied from the constant flow valve 15 and the amount of refined water become substantially the same in a steady state.

  That is, during normal sauna operation, in a steady state, the amount of water supplied from the constant flow valve 15 and the amount of refined water are substantially the same, and the humidification amount to the sauna chamber 1 is also stable.

  However, the humidification amount to the sauna room 1 is assumed when the sauna room 1 is low humidity. For example, when the sauna room 1 is highly humid, such as when the sauna is operated during bathing, the above-mentioned supply water amount is It exceeds the amount of humidification. The opening and closing of the water supply valve 16 can be intermittently controlled so that the amount of supplied water does not become excessive.

  As a result, after the sauna operation is completed, the water supply valve 16 is closed, the amount of remaining water in the water storage unit 26 can be minimized with no liquid supplied, and drying when performing a drying operation in which hot air is applied to the remaining water. Time can be shortened.

  Furthermore, since there is no residual water in the liquid micronizer 3 after the drying operation, there is no need for a drain pipe, and the construction work when the liquid micronizer 3 is installed can be easily performed.

  Next, the drying operation after the sauna operation is described.

  When the normal sauna operation is finished, the water supply valve 16 is closed by the control means 31 and the liquid is not supplied. In this state, the electric heater 8 and the fan motor 9 are operated, and warm air is passed through the ventilation portion 28 shown in FIG. 3, so that the water attached in the ventilation portion 28 can be dried. In the air passage in the liquid micronizer 3, most of the portion to which water adheres is the ventilation portion 28.

  At this time, by providing the check valve 18 in the vicinity of the water supply port 17, water upstream from the check valve 18 does not contact air, and water downstream from the check valve contacts air. The amount of water is extremely small compared to the amount of water in the water supply pipe 4.

  As a result, the water upstream from the check valve that does not come into contact with air can be protected from the propagation of bacteria, and the amount of water downstream from the check valve that comes into contact with air is extremely small. There is almost no problem.

  In addition, by providing the water supply port 17 in the non-ventilating portion 29 in the liquid micronization unit 10, the warm air blown from the fan motor 9 through the upstream opening 13 a of the liquid micronization unit case 13 is supplied to the water supply port 17. Therefore, drying of water at the water supply port 17 can be suppressed. Therefore, the amount of scale (deposits such as calcium and magnesium contained in the water) generated when the water is dried can be suppressed.

  As a result, it is possible to prevent water downstream from the check valve from being dried and to prevent the water supply port 17 from sticking to the scale.

  Further, by providing a windbreak wall 30 having a plate-like wall surrounding the water supply port 17 and an opening for allowing water to flow into the water storage unit 26 in the vicinity of the water supply port 17, liquid refinement means is provided from the fan motor 9. Since the warm air blown through the upstream opening 13a of the case 13 does not directly hit the water supply port 17, drying of the water at the water supply port 17 can be further suppressed.

  As a result, it is possible to prevent water downstream from the check valve from being dried and to prevent the water supply port 17 from sticking to the scale.

  As described above, in the present embodiment, when the liquid refining device 3 is installed in the sauna chamber 1 and used as a sauna device, the liquid refining means 10 can be opened and closed intermittently to open and close the liquid refining device 10. As a result, the amount of humidification to the sauna room can be adjusted according to the humidity state of the sauna room, and the amount of water in the water storage section 26 is kept to the minimum necessary without making the inside of the sauna room 1 excessively humidified. The drying time after the sauna operation can be shortened.

  Furthermore, the supplied water can be almost completely refined, and it can be dried by the drying operation after the sauna operation is completed without draining the water that has not been refined slightly remaining in the water storage section 26. Piping construction for treating the water that could not be refined as wastewater is unnecessary, and as a result, the construction work of the sauna device is simplified.

  Furthermore, since the water supply port 17 is provided in the non-ventilating portion 29, it becomes a configuration in which warm air does not directly hit the water supply port 17 during the drying operation, so that drying of water in the water supply port 17 can be suppressed. As a result, the scale generated when the water is dried is suppressed and the water supply port 17 is prevented from sticking.

  Furthermore, by providing the windbreak wall 30 in the vicinity of the water supply port 17, it becomes a configuration in which the warm air does not directly hit the water supply port 17 during the drying operation, so that drying of water in the water supply port 17 can be further suppressed. . As a result, the scale generated when the water is dried is suppressed and the water supply port 17 is prevented from sticking.

  As described above, the liquid miniaturization apparatus of the present invention includes a check valve that prevents the backflow of liquid at the water supply port, thereby minimizing the portion where the liquid comes into contact with air, so that the bacteria can be replaced without replacing the liquid. Can be prevented from breeding. Furthermore, by controlling the opening and closing of the water supply valve, the amount of retained water in the liquid refinement means can be adjusted. As a result, after the miniaturization operation is completed, the water supply valve is closed and the remaining water in the water storage unit is not supplied with liquid. It is possible to shorten the drying time when performing a drying operation in which warm air is applied. Furthermore, since there is no remaining water in the liquid micronizer after the drying operation, there is no need for a drain pipe, and there is an effect that the construction work can be easily performed when the liquid micronizer is installed.

  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 water but also for other liquid refining equipment such as oil and detergent.
