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, A liquid refining means provided in the air passage between the air blowing means and the exhaust port; and a control means for controlling the liquid refining means, the heating means and the air blowing means. 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 a 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 fixed rotating units at predetermined intervals in the axial direction of the rotating shaft. Fixed to the rotating shaft and the rotating shaft Both of them have a pumping pipe for sucking water from the water storage section, and this pumping pipe has an inverted conical shape, and an opening 25 extending horizontally in the upper part of the pumping pipe between the upper rotating plate and the lower rotating plate. (Slit) is provided, and an annular backing plate supported by the cylindrical path is provided around the outside of the opening, and liquid from the water storage section is placed on the outer wall of the lower part of the pumping pipe. The roll-up prevention part which prevents rising along the said outer wall is provided, and the said objective is 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, the liquid that cannot be pumped by the pumping pipe remains in the reservoir at the end of the miniaturization operation while reliably maintaining the performance of the miniaturization. The residual water in the water storage section can be dried by stopping the liquid supply and performing the drying operation.

  In other words, during the miniaturization operation, the liquid pumped by the pumping pipe can be reliably supplied to the rotating plate, and after the miniaturization operation is completed, the water supply valve is closed and the remaining water in the reservoir is heated without supplying the 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, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a perspective view of a sauna apparatus using a liquid micronizer according to an embodiment of the present invention. As shown in FIG. 1, a liquid micronizer 3 is provided on the ceiling 2 surface of a sauna room 1. It is attached.

  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 box-shaped main body case 6 having a suction port 4 and an exhaust port 5 on the lower surface, and an air passage connecting the suction port 4 and the exhaust port 5 in the main body case 6. The heat exchanger 7 as a heating means, the fan motor 8 as a blowing means, and the liquid refinement means 9 provided between the fan motor 8 and the exhaust port 5 are provided.

  An air passage leading from the fan motor 8 to the liquid micronization means 9 is formed by the 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 water supply front-end | tip 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 has a rotating shaft 19 arranged in the vertical direction. In the axial direction of the rotating shaft 19, a plurality of rotating plates 20a, 20b, and 20c that rotate about the rotating shaft 19 are arranged at predetermined intervals. It is fixed and 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, water from the water storage unit 26 is prevented from rising along the outer wall of the pumping pipe 22 irregularly and partly while peeling from the outer wall. A rib 33 is provided as a rising prevention portion. The rib 33 is provided above the liquid level 34 of the water storage unit 26.

  Here, the rib 33 is used as the splash prevention part, and can be manufactured at a low cost. As will be described later, the rising water is made to collide with the inner wall of the cylindrical path 12, or the lower water is stored. This is because it is possible to easily provide an object for peeling off the stored water from the outer wall by dropping it into the portion 26.

  In the outer peripheral portion between the rotating plate 20a and the rotating plate 20b and the outer peripheral portion between the rotating plate 20b and the rotating plate 20c, water pumped up on the inner surface side of the pumping pipe 22 is placed on the lower rotating plate 20b, A contact plate 23 that drops onto the rotary plate 20c is provided in an annular shape.

  Note that the contact plate 23 is supported by a plurality of support bars 24 protruding from the inner wall of the cylindrical path 12.

  Moreover, as shown in FIG. 3, between the rotating plates 20a and 20b and between the rotary plates 20a and 20c of the pumping pipe 22, openings 25a and 25b, which are horizontally long openings 25 through which the pumped water is ejected by centrifugal force due to rotation. Two are provided between each.

  Furthermore, the positions of the openings 25a and 25b are shifted in the circumferential direction so that the directions in which water is ejected are different between the rotary plates 20a and 20b and between the rotary plates 20b and 20c.

  Specifically, in this embodiment, as shown in FIGS. 3C and 3D, the two openings 25a are arranged at a position of 180 degrees, the two openings 25b are arranged at a position of 180 degrees, Since the central angle θ of the openings 25a and 25b is 90 degrees, the four openings 25a and 25b can discharge the pumped water to the entire 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 means 28 includes a remote controller 30 provided with a control unit 29, a display unit and a driving operation switch (not shown), and temperature sensors 27a and 27b as temperature detection means.

  The control unit 29 has a microcomputer (hereinafter referred to as a microcomputer, not shown), and the microcomputer, as shown in FIG. 2, in response to an operation signal from the remote controller 30, a pump for supplying hot water to the heat exchanger 7, and a fan motor 8. 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, hot water is supplied from a heat source such as a gas water heater or an electric water heater (not shown) to the heat exchanger 7 shown in FIG. 2 via a pipe 31. Is supplied. Further, city water is supplied to the water supply pipe 14 through a pipe 32 as shown in FIG. The city water supplied to the water supply pipe 14 is a very small amount set by the constant flow valve 15 as shown in FIG. 2, 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 level 34, that is, the water surface approaches the lower end of the water pumping pipe 22, It winds up with the air on the water surface and moves 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, as shown in FIG. 3, 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 centrifugal force due to rotation, and shown in FIG. It hits the contact plate 23 provided in a very annular shape and falls to the rotating 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 has moved upward along the inner wall of the pumping pipe 22 and has not been ejected from the opening 25b as shown in FIG. It hits the contact plate 23 provided in an annular shape 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.

  Thus, as shown in FIG. 2, 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 moving 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. It moves right up in the state.

  That is, as shown in FIG. 3, when the positions of the openings 25a and 25b, which are two horizontally long openings 25 provided between the rotating plates, are provided at the same position in the circumferential direction, they are transmitted along the inner wall of the pumping pipe 22. Since the water that has moved upward is ejected from the first opening 25b and the water does not rise to the upper opening 25a, the opening is made so that the direction in which the water is ejected differs between the rotating plates 20a to 20c. The positions of 25a and 25b are shifted in the circumferential direction.

  In this way, as shown in FIG. 2, the water pumped up by the pumping pipe 22 is almost completely refined and mixed with heated warm air, like the water supplied to the upper rotating plate 20a, and becomes a steam state. The water is discharged from the upper opening, but a part of the water droplets are adhered to the inner wall of the cylindrical path 12 without being miniaturized, and a minute amount of water droplets are condensed on the inner wall after being miniaturized. Along the inner wall of the path 12, the water flows down to the water storage section 26 and is stored.

  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 liquid level 34 approaches the lower end of the water pumping pipe 22, the water stored in the water storage section 26 is above the water surface. The air is wound together with the air and moves upward along the inner wall of the pumping pipe 22, but some moves upward along the outer wall of the pumping pipe 22. However, the water storage that travels upward along the outer wall of the pumping pipe 22 collides with the rib 33 as the splash-up preventing portion and flows outward to collide with the inner wall of the cylindrical path 12, or It collides with the rib 33, flows downward, and returns to the water storage section 26 again.

  That is, the rib 33 plays a role of triggering the water storage moving upward to separate the portion in contact with the outer wall of the pumping pipe 22.

  Further, since the water storage particles blown outward by the ribs 33 are large, it is possible to prevent the water from being blown out from the exhaust port 5 on the airflow blown out from the fan motor 8. That is, the construction work can be easily performed, and the water droplets blown out from the exhaust port 5 are only those that are refined by the rotary plate 20a and the rotary plates 20b and 20c.

  And the warm air containing the water refined | miniaturized by the high speed rotation of the rotating plate 20a and the rotating plates 20b and 20c in this way is sent from the exhaust port 5 to the inside of the sauna room 1 as shown in FIG. Supplied as steam.

  At this time, as shown in FIG. 2, the water pumped up in the pumping pipe 22 can be refined almost completely by the rotary plate 20a and the rotary plates 20b and 20c, similarly to the water supplied to the upper rotary plate 20a. The amount of water supplied from the water supply pipe 14 to the upper surface of the upper rotating plate 20a rotating at a high speed 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 feature of the present embodiment is that the buffer amount in the steady state is the residual water at the end of the refinement (sauna) operation, and the drying operation of drying the residual water can eliminate the need for drainage. It is.

  Next, the feature point that the necessity of drainage can be eliminated will be described with reference to the flowchart of FIG. 5 regarding the drying operation after completion of the miniaturization (sauna) operation.

  First, during sauna operation, hot water is supplied to the heat exchanger 7, the fan motor 8 is operated, and the water supply valve 17 is opened.

  Then, 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 as shown in FIG. 2, and the water supply pipe 14 is connected to the upper surface of the upper rotating plate 20a. Stop water supply.

  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. As shown in FIG. 1, the air is exhausted from the exhaust port 5 to the inside of the sauna room 1 by the fan motor 8.

  As shown in FIG. 2, even when water cannot be pumped through the pumping pipe 22, the fan motor 8 is blown and the hot water circulation to the heat exchanger 7 and the auxiliary heat exchanger 11 is continued. The remaining water is gradually reduced by hot air, and the remaining amount of water gradually decreases.

  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 (S1) of the flowchart of FIG. 5, this drying operation may be performed for only 10 minutes with a timer, or as shown in (S2), the temperature provided at the inlet of the liquid micronization means 9 shown in FIG. The drying operation may be terminated using the temperature detected by the sensor 27a and the temperature sensor 27b provided at the outlet.

  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, the supplied water can be refined almost completely and slightly in the water storage section 26. Even if the remaining water that could not be refined is not discharged, it can be dried by the drying operation after the sauna operation is completed, so piping work for treating the water that could not be refined as wastewater becomes unnecessary. As a result, the construction work of the sauna device can be 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, Residual water in the water storage section can be dried by stopping the liquid supply and performing a drying operation.

  For this reason, there is no need to always discharge the water accumulated in the liquid micronizer, and the construction work of the sauna device is simplified.

  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.
