JP-A-4-11068

  The problem with the above conventional example is that the liquid is stored in the tank and the liquid is supplied to the upper surfaces of a plurality of rotating disks. This means that piping is necessary.

  That is, as described above, the conventional liquid miniaturization apparatus supplies the liquid to the upper surface of the rotating disk by circulating the liquid stored in the tank. Therefore, there is a problem that a liquid supply pipe corresponding to the number of sheets is required, the number of parts is increased both inside and outside the apparatus, and the configuration is complicated.

  Therefore, the present invention circulates the liquid stored in the tank without using power such as a pump for circulating the liquid stored in the tank, and supplies the liquid to the upper surfaces of a plurality of rotating disks with a simple configuration. It is intended to do.

  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 unit provided in the air passage between the air blowing unit and the exhaust port, and the liquid refining unit is disposed in a vertical direction, and has a cylindrical path having an upper opening and a lower opening.

The water sucked up by the (slit) can be supplied to the rotating plate. As a result, the pumping pipe also serves as the circulation of the pump and the liquid supply to the rotating plate. Liquid supply can be realized.

  Furthermore, after the miniaturization operation is completed, the water supply valve is closed, the liquid is not supplied, and the water is pumped by the rotating means having the pumping pipe and supplied to the rotating plate, so that a small amount of liquid cannot be pumped by the pumping pipe.

As shown in FIG. 1, a liquid micronizer 3 is provided on a ceiling surface 2 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 main body case 6 having a suction port 4 and an exhaust port 5, and heating provided in an air passage connecting the suction port 4 and the exhaust port 5 in the main body case 6. A heat exchanger 7 as means, a fan motor 8 as air blowing means, and a liquid refinement means 9 provided between the fan motor 8 and the exhaust port 5 are provided.

  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 in the cylindrical path 12. And a water supply pipe 14 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 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 includes a rotating shaft 19 arranged in the vertical direction, a pumping pipe 22 that is fixed to the rotating shaft 19 and sucks water from a water storage section described later, and a rotating shaft on the outer surface of the pumping pipe 22. A plurality of rotating plates 20a, 20b, and 20c that rotate about the rotating shaft 19 are fixed at predetermined intervals in the axial direction of 19. 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 the rotating plate 20a closes the upper opening of the inverted conical pumping pipe 22 as shown in FIG. The rotary plate 20b and the rotary plate 20c have a circular shape provided on the outer surface of the inverted conical pumping pipe 22.

  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 provided in an annular shape. These are 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 between the rotary plates for jetting the pumped water by centrifugal force by rotation, and the directions of jetting the water are different between the rotary plates. Thus, the position of the opening 25 is shifted in the circumferential direction. As shown in FIGS. 3C and 3D, in the case of three rotating plates, the central angle θ of one opening 25a (25b) is 90 degrees, and this angle is shifted in the circumferential direction. 25, the pumped water can be ejected 360 degrees all around.

  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 operation of the above configuration will be described.

  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 the pipe 28 shown in FIG. Is done. Further, city water is supplied to the water supply pipe 14 through a pipe 29. 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 and is not discharged from the water supply pipe 14 until the rotary motor 21 is driven. .

  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, and the sucked air is absorbed by the heat exchanger 7. Heated. 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 plate 20a and the rotary plate 20b 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 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 the first opening 25b. Since the water does not come up to the upper opening 25a, the direction of the opening 25 is set so that the direction in which the water is ejected is different between the rotary plates 20a to 20c as described above with reference to FIG. The position is shifted in the circumferential direction.

  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 unit 26 and is stored.

  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 supplied as steam from the exhaust port 5 to the inside of the sauna chamber 1 by the blowing of the fan motor 8.

  As described above, the pumping pipe 22 is rotated by the same rotary motor 21 as the rotary plates 20a, 20b, and 20c, so that the water accumulated in the water storage section 26 is sucked up and the sucked-up water is taken up by the upper rotary plate 20a ( 20b) and the lower rotating plate 20b (20c) can be supplied to the rotating plate 20b (20c) by ejecting from the horizontally long opening 25 and dropping it onto the abutting plate 23 provided in an annular shape. The pumping pipe 22 also serves as a circulation of the pump and water supply to the rotating plate 20b (20c), and it is possible to realize water circulation and water supply to the rotating plate 20b (20c) with a simple configuration. it can.

  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 remaining water at the end of the miniaturization (sauna) operation, and the drying operation after the end of the miniaturization (sauna) operation that can eliminate the need for drainage will be described.

  When the sauna operation is finished, 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 20a 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.

  This drying operation may be performed only for 10 minutes with a timer, and the temperatures (T1, T2) detected by the temperature sensor 27a provided at the inlet and the temperature sensor 27b provided at the outlet shown in FIG. It may be used to end the drying operation.

  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 (X) at 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.

  In addition, if a drain outlet etc. are provided in the lowest part of the water storage part 26 and residual water is discharged | emitted, even if it does not perform said drying operation, the sanitary problem by residual water can be eliminated.

  As mentioned above, in this Embodiment, when said liquid refinement | miniaturization apparatus 3 is installed in the sauna chamber 1 and is used as a sauna apparatus, the pumping pipe 22 is rotated with the same rotary motor 21 as the rotating plates 20a, 20b, 20c. Thus, the water accumulated in the water storage section 26 is sucked up, and the water sucked up by the horizontally long opening 25 between the upper rotating plate 20a (20b) and the lower rotating plate 20b (20c) is rotated by the rotating plate 20b ( 20c), and as a result, the pumping pipe 22 also serves as the circulation of the pump and the water supply to the rotating plate 20b (20c). With a simple configuration, the water circulation and the rotating plate 20b (20c) can be performed. Water supply can be realized.

  Further, the sucked-up water is ejected from a horizontally long opening 25 provided between the upper rotating plate 20a (20b) and the lower rotating plate 20b (20c) and dropped onto a contact plate 23 provided in an annular shape. Can be supplied to the rotating plate 20b (20c), so that the supplied water can be almost completely refined, and the sauna operation can be performed without draining the water that remains slightly in the water storage section 26 and cannot be refined. Since it can be dried by the drying operation after the completion, the construction work of piping for treating the water that could not be refined as waste water becomes unnecessary, and as a result, the construction work of the sauna device is simplified.

  As described above, the liquid miniaturization apparatus of the present invention sucks up the water accumulated in the water storage section by rotating the pumping pipe with the same rotary motor as the rotary plate, and between the upper rotary plate and the lower rotary plate. The water sucked up by the long opening (slit) in the horizontal direction can be supplied to the rotating plate. As a result, the pumping pipe also serves as the circulation of the pump and the liquid supply to the rotating plate. Circulation and liquid supply to the rotating plate can be realized. Furthermore, even if the liquid that could not be refined accumulates in the water storage part in the liquid refiner, it can be refined because it can be pumped up by a rotating means having a pumping tube and supplied to the rotating plate many times. At the end of the micronization operation, the liquid that cannot be pumped by the pumping pipe remains in the water storage unit, and the liquid supply is stopped and the residual water in the water storage unit can be dried by performing the drying operation. There is no need to always drain the accumulated water, 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.
