Here, the rotating shaft 19 and the pumping pipe 22 are arranged in the vertical direction. The pumping pipe 22 is fixed to the rotary shaft 19 and sucks water from the water storage section 26. The first rotary plate 20 a, the second rotary plate 20 b, and the third rotary plate 20 c are fixed at a predetermined interval in the axial direction of the rotary shaft 19, and rotate around the rotary shaft 19. In the present embodiment, a first rotary plate 20a, a second rotary plate 20b, a third rotary plate 20c, and three rotary plates are provided from the upper side to the lower side of the rotary shaft 19. A rotating motor 21 for rotating the rotating shaft 19 is provided on the upper portion of the rotating unit 13.

And the front-end | tip of the water supply pipe | tube 14 is arrange | positioned from the rotating shaft 19 with respect to the rotation part of the 1st rotation board 20a.

Between the first rotary plate 20a and the second rotary plate 20b, and between the second rotary plate 20b and the third rotary plate 20c, the water pumped up by the pumping pipe 22 is disposed below the second rotary plate 20b. A contact plate 23 that drops onto the rotary plate 20b and the third rotary plate 20c is provided in an annular shape. The contact plate 23 is supported by a plurality of support bars 24 from the inner wall of the cylindrical path 12.

FIG. 3A is a view showing a side surface of a pumping pipe of the liquid micronizing device according to the embodiment of the present invention, FIG. 3B is a perspective view of the pumping tube of the liquid micronizing device, and FIG. 3C is a second view from 3C-3C of FIG. FIG. 3D is a view of the third rotating plate from 3D-3D of FIG. 3A.

As shown in FIG. 3A, in the circumferential direction 20e of the pumping pipe 22, horizontally-

long openings

25a and 25b through which the pumped water is spouted by the centrifugal force of rotation are respectively a first rotating plate 20a and a second rotating plate. 20b, and two each between the second rotating plate 20b and the third rotating plate 20c. The positions of the

openings

25a and 25b are circumferential so that the directions in which water is ejected are different between the first rotating plate 20a and the second rotating plate 20b and between the second rotating plate 20b and the third rotating plate 20c. It is shifted to 20e.

Further, as shown in FIG. 3B, the pumping pipe 22 has an inverted conical shape in which the upper portion 20g is larger than the lower portion 20f. The first rotating plate 20 a has a disk shape that closes the upper opening of the pumped water pipe 22. The second rotating plate 20b and the third rotating plate 20c are provided on the outer surface of the pumped-up pipe 22, and have an annular shape.

As shown in FIGS. 3C and 3D, when there are three rotating plates, the central angle θ of each

opening

25a, 25b is 90 degrees. Since the

openings

25a and 25b are shifted in the circumferential direction, the water pumped up by the four

openings

25a and 25b is jetted to the entire 360 degrees.

In addition, as shown in FIG. 2, the vertical cross-sectional shape of the water storage unit 26 is lower than the upper part so that the amount of water that cannot be pumped by the pumping pipe 22, that is, the water storage amount remaining in the water storage unit 26 at the end of the refining operation is reduced. The lower part has a small inverted trapezoidal shape. The contact plate 23 includes a first rotating plate 20a and a second rotating plate 20b, a vertical line 20d passing through the outer edge of the rotating plate between the second rotating plate 20b and the third rotating plate 20c, and an opening 25a. The liquid ejected from the

openings

25a and 25b is applied in a ring shape with respect to 25b.

Further, a temperature sensor 27 a is provided in the vicinity of the lower opening 31, and a temperature sensor 27 b is provided in the vicinity of the upper opening 30.

Further, the lower inner wall 40 of the cylindrical path 12 and the water storage portion inner surface 41 of the water storage portion 26 may be subjected to a hydrophilic treatment. Here, the hydrophilization treatment means that the surfaces of the lower inner wall 40 and the water storage portion inner surface 41 are provided with irregularities to be roughened. As a result, the water droplets adhering to the surfaces of the lower inner wall 40 and the water reservoir inner surface 41 spread thinly. In the present embodiment, the cylindrical path 12 and the water storage section 26 are resin-molded by a textured mold, and the lower inner wall 40 and the water storage section inner surface 41 are hydrophilized.

In the hydrophilization treatment, a hydrophilizing material may be kneaded into the lower inner wall 40 and the water storage unit inner surface 41. Further, the hydrophilizing material may cover the lower inner wall 40 and the water reservoir inner surface 41.

When the lower inner wall 40 and the water reservoir inner surface 41 are hydrophilized, the drying time of the lower inner wall 40 and the water reservoir inner surface 41 is shortened during the drying operation. This is because the lower inner wall 40 and the water reservoir inner surface 41 are roughened and roughened, so that the attached water droplets spread thinly on the surfaces of the lower inner wall 40 and the water reservoir inner surface 41. For this reason, the contact area between the thinly spread water droplets and the hot air is increased, and the efficiency of the drying operation is increased.

Further, when the cylindrical path 12 and the water storage part 26 are formed by embossing, the lower inner wall 40 and the water storage part inner surface 41 are easily subjected to a hydrophilic treatment. Further, when a hydrophilic material such as titanium oxide is kneaded into the lower inner wall 40 and the water reservoir inner surface 41, for example, a uniform hydrophilic treatment is performed, and a labor for performing a new hydrophilic treatment is saved. Further, when the hydrophilic material covers the lower inner wall 40 and the water reservoir inner surface 41, the hydrophilic treatment is performed while confirming a suitable range, so that a more appropriate hydrophilic treatment is performed.

Next, the configuration of the control device 43 that controls the liquid refinement device 3 will be described with reference to FIG. FIG. 4 is a block diagram of a control device of the liquid micronizing device according to the embodiment of the present invention. As shown in FIG. 4, the control device 43 includes a control unit 44, a remote controller 45 including a display unit and a driving operation switch (not shown), and

temperature sensors

27a and 27b.

The control unit 44 has a microcomputer (hereinafter referred to as a microcomputer, not shown). The microcomputer performs control of the pump that supplies hot water to the heat exchanger 7, control of the fan motor 8, control of the rotary motor 21 that drives the rotary shaft 19, control of the water supply valve 17, and the like by an operation signal from the remote controller 45. .

When the sauna is used in the sauna room 1, 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 through the pipe 28 shown in FIG. . 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 set by the constant flow valve 15 and is very small. The city water supplied to the water supply pipe 14 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 chamber 1 from the suction port 4, and the sucked air is heated by the heat exchanger 7. . The heated air is sent by the fan motor 8 to the cylindrical path 12 through 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 first rotary plate 20a and the second rotary plate 20b are rotated at a high speed.

At this time, the water supply pipe 14 supplies water at a flow rate set by the constant flow valve 15 to a position close to the rotary shaft 19 on the upper surface of the first rotary plate 20a that rotates at high speed. The water supplied to the upper surface of the first rotating plate 20a spreads in the form of a thin film toward the outer periphery due to the centrifugal force caused by the high speed rotation. The water in the form of a thin film is blown off at high speed in the tangential direction from the outer peripheral edge of the first rotating plate 20a. As described above, 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.

On the other hand, among the water droplets scattered by the centrifugal force from the first rotating plate 20a, water droplets that are not miniaturized and adhere to the inner wall of the cylindrical path 12, and a minute amount of water droplets that are condensed on the inner wall after being miniaturized are: It flows along the inner wall of the cylindrical path | route 12, it flows down to the water storage part 26, and is stored. At this time, the pumping pipe 22 is rotating above the water reservoir 26. Therefore, when the amount of water stored in the water storage section 26 increases and the water surface of the water storage section 26 approaches the lower end of the pumping pipe 22, the water in the water storage section 26 is rolled up together with the air on the water surface and travels upward along the inner wall of the water pumping pipe 22. Move to.

That is, since the pumping pipe 22 has an inverted conical shape as described above, a suction force acts inside the pumping pipe 22. For this reason, the water 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. And the water which moved upward along the inner wall of the pumping pipe 22 is spouted by the centrifugal force from the opening 25b between the 2nd rotary plate 20b and the 3rd rotary plate 20c, and the contact plate provided in cyclic | annular form 23 and falls to the third rotating plate 20c.

The water that has dropped onto the third rotating plate 20c spreads in a thin film toward the outer periphery by centrifugal force due to high-speed rotation, similar to the water supplied to the upper surface of the first rotating plate 20a. The water in the form of a thin film is blown off at high speed in the tangential direction from the outer peripheral edge of the third rotating plate 20c.

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 is ejected from the opening 25a by centrifugal force due to rotation, hits the contact plate 23 provided in an annular shape, and the second rotating plate. Fall to 20b. Similarly to the water supplied to the upper surface of the first rotating plate 20a, the water that has dropped onto the second rotating plate 20b spreads in a thin film toward the outer periphery due to centrifugal force due to high-speed rotation. The water in the form of a thin film is blown off at high speed in the tangential direction from the outer peripheral edge of the second rotating plate 20b.

Thus, the water droplets scattered by the centrifugal force collide with the inner wall of the cylindrical path 12 and are crushed, thereby promoting the refinement of water. Also, the water that moves upward along the inner wall of the pumping pipe 22 is not directly swirled in a spiral shape, but is rotated almost uniformly over the entire inner wall because the rotary motor 21 rotates at a high speed. Move to.

That is, two horizontally

long openings

25a and 25b provided between the first rotary plate 20a, the second rotary plate 20b, and the third rotary plate 20c, respectively. When the second rotary plate 20b and the third rotary plate 20c are provided at the same circumferential position, the following occurs. The water that has moved upward along the inner wall of the pumping pipe 22 is ejected from the lower opening 25b, and the water does not rise to the upper opening 25a. In this case, the amount of water ejected from the opening 25b increases, which poses a problem for uniform miniaturization. Therefore, as shown in FIG. 3A, water is uniformly supplied from the

openings

25a and 25b so that the direction in which water is ejected is different among the first rotary plate 20a, the second rotary plate 20b, and the third rotary plate 20c. The position of the opening 25 is shifted in the circumferential direction 20e of the first rotating plate 20a, the second rotating plate 20b, and the third rotating plate 20c so as to be ejected.

Further, water droplets that have not been refined and adhered to the inner wall of the cylindrical path 12 and a minute amount of water droplets that have condensed on the inner wall after being refined flow down to the water storage section 26 along the inner wall of the cylindrical path 12, Water is stored. The steam formed by the high-speed rotation of the first rotating plate 20a, the second rotating plate 20b, and the third rotating plate 20c is supplied from the exhaust port 5 to the inside of the sauna chamber 1 by the fan motor 8. The

As described above, the pumping pipe 22 is rotated by the same rotary motor 21 as the first rotary plate 20a, the second rotary plate 20b, and the third rotary plate 20c. The water accumulated in the water storage unit 26 is sucked up by the pumping pipe 22. The sucked water is ejected from

openings

25a and 25b provided between the first rotating plate 20a and the second rotating plate 20b and between the second rotating plate 20b and the third rotating plate 20c. Is done. The ejected water hits the contact plate 23 provided in an annular shape and is supplied to the second rotary plate 20b and the third rotary plate 20c. Here, the pumping pipe 22 serves as a circulation of the pump and water supply to the second rotating plate 20b and the third rotating plate 20c. With such a simple configuration, water circulation and water supply to the second rotating plate 20b and the third rotating plate 20c are realized.

Here, in order for the water supplied to the first rotating plate 20a to be almost completely refined, the amount of water supplied from the water supply pipe 14 to the upper surface of the first rotating plate 20a is a problem. Become. That is, the amount of water supplied to the upper surface of the first rotating plate 20a is determined by the micronization capability of the liquid micronizer 9, and is, for example, 30 cc / min. The micronization capability of the liquid micronizer 9 is determined by the number of the first rotary plate 20a, the second rotary plate 20b, the third rotary plate 20c, the rotational speed of the rotary motor 21, and the like.

However, the constant flow valve 15 causes variations in the flow rate depending on the water temperature and water pressure. Therefore, a buffer function is provided for the amount of water stored in the water storage unit 26 and the amount of water stored in the pumping pipe 22.

Next, a drying operation for drying the water storage section 26 after completion of the miniaturization (sauna) operation for forming water droplets in the cylindrical path 12 will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing a drying operation of the liquid micronizer according to the embodiment of the present invention.

As shown in FIG. 5, when the sauna operation is ended by the operation of the timer or the remote controller 45, the water supply valve 17 is closed, and the supply of water from the water supply pipe 14 to the upper surface of the first rotating plate 20a is stopped. The water supply source 26 is the only water supply source at this time. When pumping by the pumping pipe 22 is possible, water is supplied to the second rotating plate 20b and the third rotating plate 20c by the pumping pipe 22. Most of the supplied water is refined and supplied from the exhaust port 5 to the inside of the sauna room 1 by the fan motor 8.

When water cannot be pumped by the water pump 22, the water remaining in the water storage section 26 is gradually reduced by the hot air from the fan motor 8. In the case of the present embodiment, the amount of residual water in the water storage unit 26 when pumping by the pumping pipe 22 becomes impossible is about 5 cc from the experiment, and if the drying operation is performed for 10 minutes, there is no residual water in the water storage unit 26. .

This drying operation may be performed only for 10 minutes by a timer. Further, the drying operation may be controlled using the temperatures (T1, T2) detected by the temperature sensor 27a provided at the inlet of the liquid micronization unit 9 and the temperature sensor 27b provided at the outlet shown in FIG. 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 micronization unit 9, the heat of vaporization is taken away from the blown air due to the evaporation of water. As a result, since the air temperature at the outlet becomes lower than the air temperature at the inlet, the drying state may be determined from the temperature difference (X) at the inlet and outlet, and the drying operation may be terminated.

Here, when a humidity sensor is used instead of the

temperature sensors

27a and 27b, the dry state is 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, said drying operation will become unnecessary and the sanitary problem by residual water can be eliminated.

The water that remains slightly in the water storage section 26 and cannot be refined in this way is evaporated by the drying operation after the sauna operation is finished, even if it is not discharged. Therefore, drainage piping is not necessary. In addition, when more water than the flow set by the variation of the constant flow valve 15 is supplied to the upper surface of the first rotating plate 20 a, the water is stored in the water storage unit 26.

Note that the control unit 44 operates the fan motor 8 in a state in which the air blowing capacity is lowered during the drying operation as compared with the normal liquid refinement operation (sauna operation). Specifically, as shown in FIG. 5, in the drying operation, the control unit 44 closes the water supply valve 17. The operation of the heat exchanger 7, the fan motor 8, and the rotary motor 21 is continued in a state where the supply of water from the water supply pipe 14 to the upper surface of the first rotary plate 20a is stopped. At this time, the fan motor 8 performs the drying operation by reducing the blowing capacity by about half compared to during the sauna operation.

That is, in the present embodiment, the rotary motor 21 is driven by the control unit 44 even during the drying operation. Therefore, the water accumulated in the water storage unit 26 is pumped by the pumping pipe 22 and supplied to the second rotary plate 20b and the third rotary plate 20c, and the water is refined. The refined water is supplied from the exhaust port 5 to the inside of the sauna room 1 by blowing air from the fan motor 8.

As a result, the water accumulated in the water storage unit 26 gradually decreases, and eventually the pumping pipe 22 cannot pump the water (in the case of the present embodiment, the water storage unit 26 remaining when the pumping pipe 22 cannot pump the water). The amount of water is about 5 cc, which is very small). However, even in this state, the fan motor 8 is driven, and hot water circulation is continued in the heat exchanger 7. Therefore, the warm air from the fan motor 8 is blown to a small amount of water remaining in the water reservoir 26, and the water reservoir 26 is dried.

Also, the warm air from the fan motor 8 enters the inside of the pumping pipe 22 from the lower end of the pumping pipe 22, ascends inside the pumping pipe 22, and is released toward the contact plate 23 from the

openings

25a and 25b. Therefore, the water adhering to the inner surface of the pumping pipe 22, the contact plate 23, the first rotary plate 20a, the second rotary plate 20b, and the third rotary plate 20c is also efficiently dried.

In the present embodiment, the reason why the fan motor 8 is operated in a state in which the air blowing capacity is lowered in the drying operation as compared with the normal liquid refinement operation (sauna operation) is to reduce the operation sound. . In other words, since the drying operation is performed, for example, at midnight after the sauna operation is completed, it is desirable that the operation sound be smaller than shortening the drying time.

In addition, for the silent operation during the drying operation, if the operation in which the rotation speed of the rotary motor 21 is lower than that during the liquid refinement operation (sauna operation) is performed during the drying operation, the silent operation is further performed. Is possible.

Next, the opening / closing control of the water supply valve 17 according to the humidity of the sauna room 1 will be described. 6A is a block diagram of a control device using the temperature detection unit of the liquid micronization device according to the embodiment of the present invention, FIG. 6B is a block diagram of a control device using the humidity detection unit of the liquid micronization device, and FIG. 6C. FIG. 3 is a block diagram of a control device using a water level detection unit of the liquid micronizer. 7A is a flowchart showing the control of the humidification amount adjustment operation using the temperature detection unit of the liquid micronization device according to the embodiment of the present invention, and FIG. 7B is the humidification amount adjustment using the humidity detection unit of the liquid micronization device. FIG. 7C is a flowchart showing the control of the humidification amount adjustment operation using the water level detection unit of the liquid micronizer.

As shown in FIG. 6A, the control device 43 uses

temperature sensors

27a and 27b, and its flowchart is shown in FIG. 7A. As shown in FIG. 7A, during normal sauna operation, the heat exchanger 7 is water-flowed, the fan motor 8 and the rotary motor 21 are operated, and the water supply valve 17 is opened (S1).

When the sauna chamber 1 becomes highly humid, the difference between the detected temperatures (T1, T2) between the temperature sensor 27a provided in the lower opening 31 and the temperature sensor 27b provided in the upper opening 30 shown in FIG. (X) becomes smaller. That is, when the air flowing in from the inlet of the liquid refinement unit 9 becomes highly humid, the humidification amount that is the amount of liquid refinement in the liquid refinement unit 9 decreases. Therefore, the amount of heat taken away by the heat of vaporization decreases, and the temperature difference between the temperature sensor 27a and the temperature sensor 27b becomes smaller. By detecting this change in temperature difference and closing the water supply valve 17, the opening and closing of the water supply valve 17 is controlled so that the amount of water supply does not become excessive.

The timing at which the closed water supply valve 17 is opened is determined by the amount of water stored in the water storage unit 26 and the buffer capacity given to the amount of pumped water in the pumping pipe 22. The timing at which the water supply valve 17 is opened from an experiment or the like is preferably 5 to 10 minutes after the water supply valve 17 is closed.

A humidity sensor 46 may be provided at the suction port 4 instead of the

temperature sensors

27a and 27b. The configuration of the control device 43 at that time is FIG. 6B, and the flowchart is FIG. 7B. That is, since the humidity of the sauna room 1 is directly detected, the humidity control of the sauna room 1 can be accurately performed. For example, the water supply valve 17 may be closed when the humidity becomes 80% or more, and the water supply valve 17 may be opened when the humidity becomes 70% or less.

Furthermore, a water level sensor 47 that detects the water level of the water storage unit 26 may be used instead of the

temperature sensors

27a and 27b and the humidity sensor 46. The configuration of the control device 43 at that time is FIG. 6C, and the flowchart is FIG. 7C. That is, when the amount of water supplied to the rotating unit 13 exceeds the amount of humidification, the water level of the water storage unit 26 rises. The raised water level H may be detected and the water supply valve 17 may be closed. Further, the water level sensor 47 may detect the low water level L and the water supply valve 17 may be opened.

Next, the prevention of the drop efficiency of water droplets will be described. When the pumping pipe 22 is rotated, water rises from the water storage section 26 along the outer surface of the pumping pipe 22. Since the raised water collides with the cylindrical path 12 in the form of large water droplets, the water droplets are not sufficiently refined and the efficiency of crushing the water droplets decreases.

FIG. 8A is a view showing a side surface of a different pumping pipe of the liquid refinement apparatus according to the embodiment of the present invention, and FIG. 8B is a perspective view of a different pumping pipe of the liquid refinement apparatus. As shown in FIG. 8A and FIG. 8B, a rib as a liquid rise prevention unit that prevents water from rising from the water storage unit 26 is provided on the outer surface of the pumping pipe 22 a below the third rotary plate 20 c on the lowermost side. 53 is provided. The rib 53 is provided above the liquid level 54 of the water storage unit 26. The rib 53 can be easily provided and can be manufactured at low cost.

When the amount of water stored in the water storage section 26 increases and the liquid level 54 approaches the lower end of the pumping pipe 22, the water in the water storage section 26 is rolled up with the air on the water surface. Most of the water in the reservoir 26 moves upward along the inner surface of the pumping pipe 22, but there is also water that moves upward along the outer surface of the pumping pipe 22. However, the water moving upward along the outer surface of the pumping pipe 22 collides with the rib 53, flows downward, and returns to the water storage unit 26 again.

Further, since the water particles blown outward from the ribs 53 are large, it is possible to prevent the water from being blown out from the exhaust port 5 on the air flow blown out from the fan motor 8. That is, the water droplets blown out from the exhaust port 5 are only water droplets refined by the first rotating plate 20a, the second rotating plate 20b, and the third rotating plate 20c.

FIG. 9 is an internal perspective view of a liquid micronizing unit of the liquid micronizing device according to the embodiment of the present invention, and FIG. 10 is an internal perspective view showing an air path constituted by a cylindrical path and a water storage unit of the liquid micronizing device. FIG. As shown in FIGS. 9 and 10, the water reservoir 26 is provided with a protrusion 62 that communicates with the opening 64. A float 63 is disposed in the protrusion 62 as a water level detection unit that detects the water level of the water storage unit 26.

The water storage unit 26 has a bottom surface 67 and an edge portion 68 rising from the outer periphery of the bottom surface 67. As shown by the solid line B in FIG. 10, an air passage is formed between the upper opening 30 provided in the cylindrical path 12 and the lower opening 31.

In the present embodiment, the fan casing 10 is connected upstream of the lower opening 31. Air from the fan motor 8 flows into the lower opening 31, passes through the water reservoir 26, and flows upward in the cylindrical path 12 from the lower side. As shown by a solid line A in FIG. 9, the air from the fan motor 8 passes through these gaps and is discharged from the upper opening 30 of the cylindrical path 12.

Further, as shown in FIG. 10, the lower opening 31 has a part of the lower end of the cylindrical path 12 cut out. A notch 61 is provided at the edge 68 of the water reservoir 26 in contact with the lower opening 31. As a result, the air from the fan motor 8 flows into the water reservoir 26 through the lower opening 31 and the notch 61, and the air inflow area to the lower opening 31 is downward toward the bottom surface 67 of the water reservoir 26. Expanding.

Next, the float 63 will be described. As shown in FIG. 10, an opening 64 is provided at the edge 68 of the water storage section 26. The projecting portion 62 is a rectangular parallelepiped that is hollow with the side surface on the water storage portion 26 side opened relative to the opening 64. A float 63 is disposed on the protrusion 62.

FIG. 11 is a cross-sectional view taken along the line 11-11 in FIG. As shown in FIG. 11, the float 63 detects the water level 65 during sauna operation. When the water level of the water storage section 26 becomes equal to or higher than the water level 65 during the sauna operation, the first switch (not shown) of the float 63 is opened, the power supply to the water supply valve 17 is cut off, and the water supply from the water supply pipe 14 is stopped. In other words, during the sauna operation, water is stored in the water storage section 26 up to the water level 65 during the sauna operation.

Also, an abnormal water level 66 is set above the water level 65 during sauna operation. When the float 63 rises to the abnormal water level 66, the second switch (not shown) of the float 63 is opened, the power supply to the water supply valve 17 is cut off, and the water supply from the water supply pipe 14 is stopped. Then, the operation of the fan motor 8 and the rotary motor 21 is stopped, and the operation of the sauna device is stopped.

A plurality of partition ribs 37 are provided above the bottom surface of the water reservoir 26. The height of the partition ribs 37 is preferably the same height as the abnormal water level 66, and is lower than the notch lower end 69 of the notch 61.

Next, the screen ribs 37 will be described. FIG. 12 is a top view of the water storage section of the liquid micronizer according to the embodiment of the present invention. As shown in FIG. 12, a plurality of

partition ribs

37a, 37b, 37c,..., 37k formed in a flat plate are arranged around the pumping pipe 22. The

partition ribs

37a, 37b, 37c in the vicinity of the notch lower end 69 may be parallel to the opening 64 or may be inclined. That is, the

partition ribs

37 a, 37 b, and 37 c are provided substantially in parallel with the air inflow direction from the lower opening 31 to the water reservoir 26.

Further, each of the

partition ribs

37c, 37d, 37e, and 37f in the vicinity of the opening 64 is disposed with an interval L1. The screen ribs 37c are arranged so as to be slightly inclined toward the protrusion 62. That is, the

partition ribs

37d, 37e, and 37f are arranged substantially parallel to the opening 64, and the partition rib 37c is inclined δ with respect to the partition rib 37e.

Further, a plurality of

partition ribs

37h, 37i, 37j,... Are provided radially around the pumping pipe 22. The partition ribs 37 l are formed perpendicular to the opening 64.

The water stored in the water storage section 26 is caught in the high speed rotation of the pumping pipe 22 and starts rotating in the same direction as the rotation direction of the pumping pipe 22. Furthermore, the surface of the water undulates due to the action of the airflow along the surface of the water. The screen ribs 37 act to reduce the fluctuation of the water surface and suppress the fluctuation of the float 63.

That is, the plurality of

partition ribs

37i, 37j, etc. provided radially from the pumping pipe 22 can rotate even if the water around the outer periphery of the pumping pipe 22 is swung into the high-speed rotation of the pumping pipe 22. To prevent. This is because the

partition ribs

37i, 37j and the like are provided with resistance because they are provided in a direction that shields the rotating flow, that is, substantially perpendicular to the rotating direction.

Next, each of the

partition ribs

37c, 37d, 37e, and 37f in the vicinity of the opening 64 is disposed with the interval L1, so that the undulating water surface is prevented from entering the protruding portion 62. Further, the partition ribs 37k and 37l prevent the waves that are generated when the air flowing in from the lower opening 31 flows along the water surface from spreading. Therefore, since the water level 65 during the sauna operation is stable, the float 63 can accurately detect the water level.

As described above, the residual water that accumulates in the water storage section 26 during the sauna operation is extremely small, and the water level 65 during the sauna operation is also stable. For this reason, the amount of water flowing into the protrusion 62 through the opening 64 is small, and the float 63 is maintained at a water level that is slightly lifted from the bottom surface of the protrusion 62.

Further, as the drying operation proceeds, the remaining water in the water storage section 26 decreases and the water level decreases, so that the ratio of air blown from the fan motor 8 to the screen ribs 37 increases. The

screen ribs

37c, 37i, 37j and the like have an action of deflecting the flow along the bottom surface 67 of the water storage section 26. Therefore, the ventilation in the water storage part 26 is stirred and the drying in the water storage part 26 is accelerated | stimulated. Further, the air blown from the fan motor 8 also travels from the opening 64 into the projecting portion 62 to dry the projecting portion 62.

Thus, even if a very small amount of water remains in the liquid micronizer 3, the residual water is dried by the drying operation, so that the waste water in the liquid micronizer 3 need not be drained.

On the other hand, during the sauna operation, for example, due to a failure of the constant flow valve 15, water of a predetermined flow rate or higher is supplied to the first rotating plate 20 a, and excess water having a water level of 65 or higher during the sauna operation is stored in the water storage unit 26. Will accumulate. In such a case, the float 63 arranged in the protrusion 62 detects the abnormal water level 66 and interrupts the energization of the water supply valve 17. Then, water supply from the water supply pipe 14 is stopped, the operation of the fan motor 8 and the rotary motor 21 is stopped, and the operation of the sauna device is stopped.

Thus, when the float 63 detects the water level abnormality, the operation of the sauna device is stopped before water leaks from, for example, the joint between the upper end of the water storage section 26 and the lower end of the cylindrical path 12.

The liquid refinement apparatus of the present invention and a sauna apparatus using the same are expected to be used for sauna apparatuses, humidification apparatuses, cooling apparatuses, spraying apparatuses, cleaning apparatuses, plant growing facilities, and the like. Further, it can be used not only for water but also for liquid miniaturization equipment such as oil and detergent.
