JP-A-6-63103

  The problem with the above conventional example is that in order to discharge the liquid ejected from the nozzle that could not be refined, piping must be installed in the sauna room, and construction work when installing the sauna device Is complicated.

  In other words, in the type in which the liquid is ejected from the nozzle to refine the liquid, the liquid cannot be completely refined, and the sauna is used to process a large amount of liquid remaining in the sauna apparatus that cannot be refined. A pipe is extended to the room so that the liquid that cannot be refined is discharged into the sauna room. It is very troublesome to construct such a pipe in the sauna room aesthetically.

  Therefore, an object of the present invention is to make it possible to easily perform construction work when installing a sauna apparatus.

  And in order to achieve this object, the present invention comprises a main body case having a suction port and an exhaust port, a heating unit and a blower unit provided in an air passage connecting the suction port and the exhaust port in the main body case, The liquid refinement means provided in the air passage between the blower means and the exhaust port, and the liquid refinement means, the heating means, and the control means for controlling the blower means, the liquid refinement means are arranged in the vertical direction A cylindrical path having an upper opening and a lower opening, a rotating means provided in the cylindrical path, a liquid supply means for supplying liquid to the rotating means, and the cylindrical path The rotating means has a rotating shaft arranged in the vertical direction, a rotating motor that rotates the rotating shaft, and a plurality of rotating plates fixed at predetermined intervals in the axial direction of the rotating shaft. And fixed to the rotating shaft A pumping pipe for sucking water from the water storage section is provided at the center of the rotating plate. The pumping tube has an inverted conical shape, and an upper portion (slit) is formed between the upper rotating plate and the lower rotating plate in the upper part (slit). ) And an annular stopper plate supported by the cylindrical path around the outside of the opening, and a lower outer wall is provided with a rising prevention portion for preventing the liquid in the water storage portion from rising. The goal has been achieved.

  As described above, the present invention provides a rotating means having a pumping pipe even if the amount of liquid supplied to the upper rotating plate increases and liquid that cannot be refined accumulates in the water storage section in the liquid refinement apparatus. As a result, liquid that cannot be pumped by the pumping pipe remains in the water storage section at the end of the micronization operation, and the liquid supply is stopped and drying operation is performed. By performing, the residual water of a water storage part can be dried.

  That is, during the miniaturization operation, the liquid pumped by the pumping pipe is surely supplied to the rotating plate and refined. After the miniaturization operation, the water supply valve is closed and the remaining water in the reservoir is warmed without supplying liquid. By applying the wind, there is no residual water in the liquid refining device after the drying operation, so a drain pipe is unnecessary, and the construction work when installing the liquid refining device can be performed easily.

  Hereinafter, in the present embodiment, the liquid to be refined will be described as water.

  As shown in FIG. 2, the liquid micronizer 3 includes a main body case 6 having a suction port 4 and an exhaust port 5, and heating means provided in an air passage connecting the suction port 4 and the exhaust port 5 in the main body case 6. And a fan motor 8 as a blowing means, and a liquid refining means 9 provided between the fan motor 8 and the exhaust port 5.

  The air passage leading from the fan motor 8 to the liquid micronization means 9 is formed by a fan casing 10, and an auxiliary heat exchanger 11 is provided between the liquid micronization means 9 and the exhaust port 5.

  As shown in FIG. 2, the liquid refinement means 9 is arranged in a vertical direction, and has a cylindrical path 12 having an upper opening and a lower opening, and a rotating means 13 provided inside the cylindrical path 12. The water supply pipe 14 is provided as a liquid supply means for supplying water to the rotating means 13. A constant flow valve 15 is provided in the water supply pipe 14, and a water supply valve 17 is provided in an upstream pipe 16 of the constant flow valve 15. And the front-end | tip which supplies the water of the water supply pipe 14 is arrange | positioned from the rotating shaft 19 with respect to the rotation part of the rotating plate 20a mentioned later.

  The rotating means 13 fixes a rotating shaft 19 arranged in the vertical direction and a plurality of rotating plates 20a, 20b, 20c rotating around the rotating shaft 19 in the axial direction of the rotating shaft 19 at predetermined intervals. Provided. In the present embodiment, the rotating plate 20a, the rotating plate 20b, the rotating plate 20c, and three rotating plates are provided from the upper side to the lower side of the rotating shaft 19.

  A rotating motor 21 for driving the rotating shaft 19 is provided at the upper part of the rotating means 13, and an inverted cone formed integrally with the rotating plate 20a, the rotating plate 20b, and the rotating plate 20c at the lower part of the rotating means 13. Shaped pumping pipes 22 are provided in the vertical direction.

  Here, on the outer wall of the lower part of the pumping pipe 22, a rising prevention part 33 that spreads from the middle of the pumping pipe 22 toward the liquid level 34 is provided, and is provided above the liquid level 34 of the water storage part 26. Here, as the shape of the rise prevention unit 33, a horizontal disk shape in the vicinity of the liquid surface 34 may be considered, and the disk shape may be reduced as it goes upward. Between the rotating plate 20a and the rotating plate 20b, and between the rotating plate 20b and the rotating plate 20c, a contact plate 23 for dropping the water pumped by the pumping pipe 22 to the lower rotating plate 20b and the rotating plate 20c is annularly formed. Provided and supported by a plurality of support bars 24 from the inner wall of the cylindrical path 12.

  As shown in FIG. 3, the pumping pipe 22 is provided with two horizontally long openings 25 (25a, 25b) between each rotating plate for discharging the pumped water by centrifugal force by rotation, and water is jetted between the rotating plates. The positions of the openings 25 are shifted in the circumferential direction so that the directions to be changed are different. As shown in FIGS. 3C and 3D, when there are three rotating plates, the central angle θ of one opening 25a (25b) is 90 degrees, and this angle is shifted in the circumferential direction. With the openings 25a and 25b, the pumped water can be ejected around 360 degrees.

  Further, as shown in FIG. 2, a water storage section 26 is provided at the lower part of the cylindrical path 12 so that the amount of water that cannot be pumped by the pumping pipe 22, that is, the water storage capacity of the water storage section 26 at the end of the miniaturization operation is reduced. The lower portion of the path 12 has, for example, an inverted trapezoidal shape (convex downward).

  As temperature detection means, a temperature sensor 27 a is provided in the lower opening of the cylindrical path 12, and a temperature sensor 27 b is provided in the upper opening of the cylindrical path 12.

  Next, the configuration of the control means 28 will be described with reference to FIG.

  The control unit 28 includes a control unit 29, a remote controller 30 including a display unit and a driving operation switch (not shown), and temperature sensors 27a and 27b as temperature detection units.

  The control unit 29 has a microcomputer (hereinafter referred to as a microcomputer, not shown). The microcomputer, in response to an operation signal from the remote controller 30, supplies a pump for supplying hot water to the heat exchanger 7 as shown in FIG. The rotary motor 21 that drives the rotary shaft 19 and the water supply valve 17 are controlled.

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

  As shown in FIG. 1, when using a sauna in the sauna room 1, first, heat exchange shown in FIG. 2 is performed from a heat source such as a gas water heater or an electric water heater (not shown) through a pipe 31 shown in FIG. Hot water is supplied to the vessel 7. Further, city water is supplied to the water supply pipe 14 through a pipe 32 as shown in FIG. As shown in FIG. 2, the city water supplied to the water supply pipe 14 is a very small amount set by the constant flow valve 15 and is stopped by the water supply valve 17 until the rotary motor 21 is driven. It is not discharged from.

  In this state, when the heat exchanger 7 is operated and the fan motor 8 is driven, the fan motor 8 sucks air in the sauna room 1 through the suction port 4 as shown in FIG. It is heated by the heat exchanger 7 as shown in FIG. The heated air is sent by the fan motor 8 to the cylindrical path 12 via the fan casing 10.

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

  At this time, the water supply pipe 14 supplies water having a flow rate set by the constant flow valve 15 to a position near the rotary shaft 19 on the upper surface of the upper rotating plate 20a that rotates at a high speed. The water supplied to the upper surface of the upper rotating plate 20a spreads in the form of a thin film toward the outer peripheral direction due to the centrifugal force caused by the high-speed rotation, and this thin film-like water is moved tangentially from the outer peripheral edge of the rotating plate 20a. It is blown away at high speed.

  In this way, the water droplets scattered by the centrifugal force collide with the inner wall of the cylindrical path 12 and are crushed, thereby promoting the miniaturization of water.

  And most of the water supplied from the water supply pipe 14 to the upper surface of the upper rotating plate 20a is miniaturized at this time, and is mixed with the above-mentioned heated warm air in a steam state.

  On the other hand, among the water droplets scattered by the centrifugal force from the upper rotating plate 20a, a few water droplets that are not miniaturized and adhere to the inner wall of the cylindrical path 12 or a minute amount of water droplets that are condensed on the inner wall after being miniaturized are Then, along the inner wall of the cylindrical path 12, it flows down to the water storage section 26 and is stored.

  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, since the pumping pipe 22 has an inverted conical shape as described above, 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.

  Then, the water moved upward along the inner wall of the pumping pipe 22 is first ejected from the opening 25b between the rotating plate 20b and the rotating plate 20c by a centrifugal force by rotation, hits the contact plate 23 provided in an annular shape, and rotates. Drops onto the plate 20c.

  Like the water supplied to the upper surface of the upper rotating plate 20a, the water that has dropped onto the rotating plate 20c spreads in a thin film shape toward the outer periphery due to centrifugal force due to high-speed rotation. It is blown away at high speed from the outer peripheral edge of the rotating plate 20c in the tangential direction.

  In this way, the water droplets scattered by the centrifugal force collide with the inner wall of the cylindrical path 12 and are crushed, thereby promoting the miniaturization of water.

  Further, the water that moved upward along the inner wall of the pumping pipe 22 and was not ejected from the opening 25b was ejected from the opening 25a between the rotating plate 20a and the rotating plate 20b by a centrifugal force by rotation, and was provided in an annular shape. It hits the contact plate 23 and falls to the rotating plate 20b.

  Like the water supplied to the upper surface of the upper rotating plate 20a, the water that has dropped onto the rotating plate 20b spreads in a thin film shape toward the outer periphery due to centrifugal force due to high-speed rotation. It is blown away at high speed from the outer peripheral edge of the rotating plate 20b in the tangential direction.

  In this way, the water droplets scattered by the centrifugal force collide with the inner wall of the cylindrical path 12 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.

  That is, when two horizontally long openings 25 (25a, 25b) provided between the rotating plates are provided at the same position in the circumferential direction, the water that has moved upward along the inner wall of the pumping pipe 22 is provided. As shown in FIG. 3, since the water is ejected from the first opening 25b and the water does not rise to the upper opening 25a, the water is ejected between the rotating plates 20a to 20c as described above with reference to FIG. The positions of the openings 25 are shifted in the circumferential direction so that the directions to be changed are different.

  As described above, the water pumped up by the pumping pipe 22 is almost all refined, similarly to the water supplied to the upper rotating plate 20a, and is mixed with heated warm air to be in a steam state and discharged from the upper opening. However, some of the water droplets are attached to the inner wall of the cylindrical path 12 without being miniaturized, or a small amount of water droplets are condensed on the inner wall after being miniaturized, and travel along the inner wall of the cylindrical path 12. Then, it flows down to the water storage section 26 and is stored as shown in FIG.

  Here, when the pumping pipe 22 is rotating above the water storage section 26, the amount of water stored in the water storage section 26 increases and the water surface approaches the lower end of the pumping pipe 22, the water stored in the water storage section 26 is stored in the air above the water surface. And move upward along the inner wall of the pumping pipe 22, but some move upward along the outer wall of the pumping pipe 22. However, the stored water which is going to move upward along the outer wall has the effect of preventing the stored water from rising and peeling along the outer wall of the rising prevention portion 33 and the pumping pipe 22 by the rising prevention portion 33. As a result, it is possible to prevent the stored water, which is larger than the finer particles generated by colliding with the airflow blown out from the fan motor 8 in the middle of being transmitted above the outer wall of the pumping pipe 22, from being blown out from the exhaust port 5. be able to. Here, as described above as an example of the shape of the ascent prevention portion 33, as shown in FIG. 2, a substantially conical shape is formed below the pumping pipe 22, and the pumping pipe starts from the bottom end. The inclined portion 35 inclined toward the line 22 has a shape that widens as it goes downward. That is, it is considered that the centrifugal force is increased by the inclined portion 35 and the force is exerted outward, and as a result, the stored water falls downward. Thereby, it is possible to easily perform the construction work, and there is a remarkable effect that water droplets blown from the exhaust port 5 are always miniaturized.

  On the other hand, warm air containing water refined by high-speed rotation of the rotary plate 20a and the rotary plates 20b and 20c is blown from the fan motor 8 to the inside of the sauna room 1 as shown in FIG. Supplied as steam.

  At this time, similarly to the water supplied to the upper rotating plate 20a, the water pumped up by the pumping tube 22 is almost completely refined, so that it is formed on the upper surface of the upper rotating plate 20a rotating at high speed from the water supply tube 14. The amount of water to supply becomes a problem. That is, the amount of water that can be refined is set by the micronization capability of the liquid micronizer 9 determined by the number of rotating plates 20a to 20c, the number of rotations of the rotary motor 21, and the like, and is, for example, 30 cc / min.

  However, since the flow rate of the constant flow valve 15 varies depending on the water temperature and water pressure, a buffer function is provided for the amount of water stored in the water storage section 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.

  The buffer amount in the steady state is the residual water at the end of the refinement (sauna) operation, and the drying operation for drying the residual water is a point that can eliminate the need for drainage.

  Next, the drying operation after the end of the miniaturization (sauna) operation, which can eliminate the need for drainage, will be described with reference to the flowchart of FIG.

  As shown in the flowchart of FIG. 5, when the sauna operation is ended by the operation of the timer or the remote controller 30, first, the water supply valve 17 is closed and the supply of water from the water supply pipe 14 to the upper surface of the upper rotating plate 20 a is stopped.

  At this time, the water supply source is only the water storage unit 26. While the pumping pipe 22 can pump the water, the pumping pipe 22 supplies water to the rotary plate 20b and the rotary plate 20c as described above, and most of the water is supplied. Is refined and discharged from the exhaust port 5 to the inside of the sauna room 1 by the ventilation of the fan motor 8.

  Water that cannot be pumped by the pumping pipe 22 and the water remaining in the water storage section 26 continues to be circulated in the hot air by the fan motor 8, the heat exchanger 7 and the auxiliary heat exchanger 11. The remaining water will gradually decrease by hitting it.

  In the case of the present embodiment, the amount of remaining water in the water storage unit 26 when pumping by the pumping pipe 22 becomes impossible is about 5 cc (from the experiment), and the remaining water in the water storage unit 26 can be dried after 10 minutes of drying operation.

  As shown in the flowchart of FIG. 5, this drying operation may be performed only for 10 minutes with a timer. The temperature sensor 27a provided at the inlet of the liquid micronizer 9 and the temperature sensor 27b provided at the outlet shown in FIG. The drying operation may be terminated using the detected temperature.

  That is, when it is desired to shorten the drying operation time as much as possible for energy saving, if there is residual water in the liquid refinement means 9, the evaporation heat is taken away from the blown air when the water evaporates. Utilizing the fact that the air temperature is lower, the drying state can be determined from the temperature difference between the entrance and exit, and the drying operation can be terminated.

  A humidity sensor may be used instead of the temperature sensors 27a and 27b, and the dry state can be determined more clearly.

  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 as shown in FIG. 1, the supplied water can be refined almost completely. As shown in 2, the water that could not be refined slightly remaining in the water storage section 26 can be dried by the drying operation after the sauna operation, so that the water that could not be refined is treated as waste water. This eliminates the need for piping construction, and as a result, the construction work of the sauna device is simplified.

  Further, for example, even when more water is supplied to the upper surface of the upper rotating plate 20a than the flow rate set by the variation of the constant flow valve 15, water can be stored by the water storage unit 26, and the stored water can be stored in the rotating plate by the pumping pipe 22. Since it can be supplied, the amount of residual water at the end of the sauna operation can be reduced and the drying operation time can be shortened.

  As described above, in the liquid micronizer of the present invention, the amount of liquid supplied to the upper rotating plate increases due to the variation of the constant flow valve, and the liquid that cannot be micronized accumulates in the water storage section in the liquid micronizer. Even if it comes, it can be pumped up by a rotating means with a pumping pipe and supplied to the rotating plate many times and can be refined.As a result, at the end of the miniaturization operation, liquid that cannot be pumped up by the pumping pipe remains in the reservoir, By stopping the liquid supply and performing the drying operation, the remaining water in the water storage section can be dried, so there is no need to constantly drain the water accumulated in the liquid micronizer, and the construction work of the sauna device is easy The effect of becoming.

  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.
