Description

  The present invention relates to a liquid miniaturization apparatus and a sauna apparatus using the same.

  For example, the configuration of a liquid micronizer used for a sauna device has the following configuration.

  That is, a main body case having an air supply port and an exhaust port, a blower means provided in an air passage in the main body case, and a liquid refinement means provided between the blower means and the exhaust port, the liquid refinement The means is configured to store liquid in a tank, supply the stored liquid to the upper surface of a rotating disk by a pump, and disperse the liquid thinly spread on the disk outward by centrifugal force to make it fine. (For example, refer to Patent Document 1 below).

JP-A-4-11068

  The problem with the above conventional example is that the efficiency of liquid miniaturization is low.

  That is, as described above, the conventional liquid miniaturization apparatus finely divides the liquid from the upper surface of the disk by centrifugal force. However, it is sufficient to scatter the liquid outward from the disk. The liquid is scattered without being miniaturized, and the efficiency of miniaturization is lowered.

  Therefore, in order to solve this problem, a method has been proposed in which a cylinder is provided on the outer periphery of the rotating plate and the liquid scattered from the rotating plate is collided to promote the refinement of the liquid. Even if it is made to collide with the inner wall of the cylinder, the collision energy cannot be effectively utilized if it is merely collided with the inner surface of the cylinder, and miniaturization is not sufficiently promoted. That is, in this case, the scattered liquid collides with the cylinder inner surface in an inclined state on the inner surface of the cylinder, so that the collision energy cannot be used for crushing, and as a result, the liquid miniaturization efficiency is low. It was something that would end up.

  Therefore, the present invention aims to improve the efficiency of liquid miniaturization.

  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. A rotating means provided in the cylindrical path, a liquid supply means for supplying a liquid to the rotating means, and a water storage section provided in a lower part of the cylindrical path. A rotating shaft arranged in a direction, a rotating motor for rotating the rotating shaft, a pumping pipe fixed to the rotating shaft and sucking water from the water storage section, and the rotating shaft on the outer surface of the pumping pipe A plurality of rotating plates fixed at predetermined intervals in the axial direction The liquid supply means includes a water supply pipe for transferring the liquid and a water supply valve disposed in the middle of the water supply pipe, and the air blowing means includes an impeller and a fan motor for rotating the impeller. And a fan casing containing the impeller, and the pumping pipe has an inverted conical shape and has a horizontally long opening (slit) between the upper rotating plate and the lower rotating plate, and sucked water Is ejected from the opening in the outer peripheral direction, and an annular backing plate supported by the cylindrical path is provided around the outer periphery of the opening, and the cylindrical path is provided on the outer periphery of the plurality of rotating plates. The crushing portion is provided, and the crushing portion has a collision surface in which a surface facing the rotation direction of the plurality of rotation plates protruding toward the rotation axis is substantially orthogonal to a tangential direction of the plurality of rotation plates. By configuring the above, the above object is achieved.

  As described above, according to the present invention, the crushing portion connected to the cylindrical path is provided on the outer periphery of the plurality of rotating plates, and the crushing portion rotates the plurality of rotating plates protruding toward the rotating shaft. The surface facing in the direction constitutes a collision surface that is substantially orthogonal to the tangential direction of the plurality of rotating plates, and by crushing the water scattered from the plurality of rotating plates by this crushing portion, the efficiency of liquid refinement is improved. Can be improved.

  That is, in the present invention, the liquid scattered from the outer edges of the plurality of rotating plates due to the centrifugal force is scattered in the substantially tangential direction of the rotating plates and collides with the collision surface of the crushing portion at a substantially right angle. Therefore, the liquid droplets diffused by the collision are crushed and the miniaturization is promoted. As a result, the efficiency of the liquid miniaturization is improved.

  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 12 a and a lower opening 12 b, and a rotation provided inside the cylindrical path 12. Means 13 and a water supply pipe 14 as liquid supply means for supplying water to the rotating means 13 are provided. 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 20 a has a disk shape that closes the upper opening of the inverted conical pumping pipe 22. The plate 20 c is formed in an annular shape provided on the outer surface of the inverted conical pumping pipe 22.

  A plurality of crushing portions 23 are provided on the outer periphery of the rotating plate 20a, the rotating plate 20b, and the rotating plate 20c so as to protrude from the inner wall of the cylindrical path 12 toward the rotating shaft 19, and the rotating plate 20a, the rotating plate 20b, and the rotating plate 20 are rotated. It is set as the structure which crushes the water scattered from the board 20c.

  When the air from the fan motor 8 is ventilated from the lower opening 12b toward the upper opening 12a, the plurality of crushing parts 23 are the rotating plate 20a, the rotating plate 20b, the rotating plate 20c, and the inner wall of the cylindrical path 12 It is the structure which contacts the air which passes the clearance gap between. The configuration of the plurality of crushing parts 23 will be described in detail later.

  Between the rotating plate 20a and the rotating plate 20b, and between the rotating plate 20b and the rotating plate 20c, a contact plate 24 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. ing.

  In the present embodiment, the annular backing plate 24 is formed integrally with the plurality of crushing portions 23. That is, the annular contact plate 24 is configured to be supported by a plurality of support rods 25 extending from the plurality of crushing portions 23 connected to the inner wall of the cylindrical path 12 toward the rotating shaft 19.

  The pumping pipe 22 is provided with two horizontally long openings (not shown) for ejecting the pumped water by centrifugal force caused by rotation between the rotating plates, so that the direction of ejecting water is different between the rotating plates. The position of the opening is shifted in the circumferential direction. For example, when there are three rotating plates, the central angle θ of one opening is 90 degrees, and this angle is shifted in the circumferential direction, so that the water that has been pumped up through all four openings (not shown) is 360 degrees. Can be spouted 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).

  Next, the plurality of crushing parts 23 will be described.

  As shown in FIG. 3, the plurality of crushing portions 23 are formed in a plurality of substantially rectangular substantially flat plate shapes, and are vertically arranged along the outer periphery of the rotating plate 20 a, the rotating plate 20 b, and the rotating plate 20 c. The respective side end portions 23 a are connected to the inner wall of the cylindrical path 12.

  The plurality of crushing portions 23 have surfaces facing the rotation direction of the rotating plate 20a, the rotating plate 20b, and the rotating plate 20c that protrude toward the rotating shaft 19, respectively, of the rotating plate 20a, the rotating plate 20b, and the rotating plate 20c. A collision surface 27 that is substantially orthogonal to the tangential direction (A in FIG. 4) is formed.

  As shown in FIGS. 3 and 4, the collision surface 27 is curved to be convex in the rotational direction so as to be substantially orthogonal to the tangential direction of the rotary plate 20 a, the rotary plate 20 b, and the rotary plate 20 c. For this reason, it is set as the structure which collides the water splashed from the rotating plate 20a, the rotating plate 20b, and the rotating plate 20c by the some crushing part 23 so that it collides so as to be substantially orthogonal to the collision surface 27, and promotes refinement | miniaturization.

  Moreover, in this Embodiment, the lower part corresponding to the upper opening part 12a of the cylindrical path | route 12 inner wall shown in FIG. 3 is the cylindrical path | route 12 of the some crushing part 23, as shown in FIG. A non-connecting portion 28 to the inner wall is provided.

  On the other hand, the inner peripheral part of the cylindrical path 12 on the outer periphery of the non-connecting part 28 of the plurality of crushing parts 23 is a connecting part 29 to the inner wall of the cylindrical path 12 of the plurality of crushing parts 23.

  In the connection part 29 of the cylindrical path | route 12, since it is set as the structure which connects the some crushing part 23, it is the tangent of the rotation plate 20a, the rotation plate 20b, and the rotation plate 20c from the rotation plate 20a, the rotation plate 20b, and the rotation plate 20c. The water scattered in the direction (A in FIG. 4) can be collided so as to be substantially orthogonal to the collision surfaces 27 of the plurality of crushing parts 23 to be crushed, thereby promoting the miniaturization.

  On the other hand, in the non-connecting portion 28 of the cylindrical path 12 described above, the plurality of crushing portions 23 are not connected to the inner wall of the cylindrical path 12. That is, since the crushing part 23 is not provided in the lower part corresponding to the upper opening 12a of the inner wall of the cylindrical path 12, the air rising up the air path on the upper opening 12a side in the cylindrical path 12 is crushed. It is set as the structure which does not contact the part 23 and does not block an air path.

  Moreover, in this Embodiment, as shown in FIG.3 and FIG.4, the upper opening part 12a part of the non-connecting part 28 of the cylindrical path | route 12 is formed in the substantially linear form. And it is set as the structure which connected the substantially flat auxiliary heat exchanger 11 to the upper opening part 12a formed in the non-connecting part 28 upper part. The non-connecting portion 28 of the cylindrical path 12 is formed in a substantially planar shape, and is used as a non-connecting portion 28 to the inner wall of the cylindrical path 12 of the crushing portion 23 up to the lower part of the cylindrical path 12.

  Further, when viewed from the upper surface of the cylindrical path 12, as shown in FIG. 4, a bulging portion is formed on the inner wall of the cylindrical path 12 so that the connecting portion between the non-connecting portion 28 and the connecting portion 29 bulges outward. 30 is formed.

  In the present embodiment, the non-connecting portion 28 that is a lower portion corresponding to the upper opening 12a of the cylindrical path 12 is formed in a substantially planar shape, and the entire cylindrical path 12 is configured in a substantially rectangular tube shape, A connecting portion between the non-connecting portion 28 and the connecting portion 29 is refracted at a substantially right angle to constitute the above-described bulging portion 30. By forming the bulging portion 30, the air path on the upper opening 12a side of the cylindrical path 12 is expanded, and as a result, the cross-sectional area of the air path on the upper opening 12a side is enlarged. .

  And as shown in FIG. 4, the some crushing part 23 is comprised in the connection part 29 of the cylindrical path | route 12 inner wall so that it may connect with the outer periphery of rotating plate 20a-20c at substantially equal intervals.

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

  When the sauna is used 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 through the pipe 31 shown in FIG. Is done. Further, city water is supplied to the water supply pipe 14 through a pipe 32. 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 from the lower opening 12 b into the cylindrical path 12 by the fan motor 8 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, the rotary plate 20b, and the rotary plate 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 a thin film shape toward the outer peripheral direction by centrifugal force due to high-speed rotation, and this thin film-shaped water is tangentially (see FIG. B) is blown away at a high speed to A) shown in FIG.

  And most of the water droplets scattered at high speed from the outer peripheral edge of the rotating plate 20a due to centrifugal force are scattered in substantially the same direction as the tangent to the rotating plate 20a (A shown in FIG. 4). Since it collides with the collision surface 27 of the crushing part 23 at a substantially right angle, the dispersed liquid droplets are effectively crushed by this collision, and miniaturization is promoted.

  Further, the water droplets collided with the collision surface 27 scatter in the gaps between the cylindrical path 12 and the plurality of crushing parts 23 and the rotating plates 20a to 20c, and adjacent to the rotating plates 20a to 20c rotating at high speed or adjacent to each other. It collides again with the crushing part 23 to be crushed, and the water is further refined.

  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, even if it collides with the collision surfaces 27 of the crushing portions 23 or the inner walls of the cylindrical path 12, the cylindrical path 12 is not refined. A small amount of water droplets adhering to the inner wall and a minute amount of water droplets condensed on the inner wall after being refined flow down the inner wall of the cylindrical path 12 and flow down to the water storage section 26 to be 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 that has moved upward along the inner wall of the pumping pipe 22 is first ejected from the opening (not shown) between the rotating plate 20b and the rotating plate 20c by a centrifugal force by rotation, and a contact plate provided in an annular shape. 24 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 (A shown in FIG. 4).

  In this way, the water droplets scattered by the centrifugal force collide with the collision surfaces 27 of the plurality of crushing portions 23 substantially orthogonal to the tangent line of the rotating plate 20c, thereby promoting water miniaturization.

  Further, some of the fine water droplets scattered by the centrifugal force collide with the inner wall of the cylindrical path 12 and are crushed, thereby further promoting the miniaturization of water.

  Further, the water that has moved upward along the inner wall of the pumping pipe 22 and was not ejected from the opening (not shown) between the rotating plate 20b and the rotating plate 20c is the opening between the rotating plate 20a and the rotating plate 20b ( It is ejected from a centrifugal force by rotation from a not-shown), hits a contact plate 24 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 (A shown in FIG. 4).

  As described above, the water droplets scattered by the centrifugal force collide with the collision surfaces 27 of the plurality of crushing portions 23 that are substantially orthogonal to the tangent line of the rotating plate 20c, thereby promoting water miniaturization.

  Further, some of the water droplets that have been scattered from the rotating plate 20c due to centrifugal force collide with the inner wall of the cylindrical path 12 and are crushed, thereby further promoting the water miniaturization.

  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 (not shown) provided between the rotary plates 20a, 20b, and 20c are provided at the same position in the circumferential direction, they pass along the inner wall of the pumping pipe 22. The water that has moved upward is ejected from the first opening (not shown) and the water does not rise to the upper opening (not shown), so that water is ejected between the rotating plates 20a to 20c. The positions of the openings (not shown) are shifted in the circumferential direction so that the directions are different.

  As described above, the water pumped up by the pumping pipe 22 is almost all the same as the water supplied to the upper rotating plate 20a and collides with the collision surface 27 of the plurality of crushing parts 23 and the inner wall of the cylindrical path 12. Is mixed with heated warm air and becomes a vapor state and is discharged from the upper opening 12a, but some water droplets attached to the inner wall of the cylindrical path 12 without being partly refined, After being miniaturized, it becomes a minute amount of water droplets condensed on the inner wall, flows down the inner wall of the cylindrical path 12, and flows down to the water storage unit 26 to be stored.

  On the other hand, warm air containing water refined by the high-speed rotation of the rotary plate 20a, the rotary plate 20b, and the rotary plate 20c is blown from the lower opening 12b of the cylindrical path 12 by the blowing of the fan motor 8 of FIG. 1 is transported by the warm air flowing toward the upper opening 12a, reheated by the auxiliary heat exchanger 11, and then the ceiling exhaust port (see FIG. 1) of the sauna room 1 of FIG. 1 through the exhaust port 5 of the main body case 6 shown in FIG. (Not shown) is supplied to the inside of the sauna room 1 as steam.

  As described above, the lower portion corresponding to the upper opening 12a formed above the outer peripheral surface of the cylindrical path 12 is the non-connecting portion 28 in which the plurality of crushing portions 23 are not provided. The liquefaction can be suppressed and the miniaturization efficiency can be improved.

  That is, the temperature of the high-temperature air blown from the lower opening 12b into the cylindrical path 12 decreases as it rises toward the upper opening 12a due to the vaporization action in the cylindrical path 12, The amount of saturated water vapor decreases. For this reason, the refined water droplets generated by causing the rotating plates 20a to 20c to collide with the collision surfaces 27 of the plurality of crushing parts 23 maintain the fine particle shape without being completely vaporized in the air. As it is, it is conveyed by the air blown into the cylindrical path 12 from the lower opening 12b.

  Thus, the air rising in the cylindrical path 12 passes through the gaps between the rotating plates 20a to 20c, the plurality of crushing portions 23, and the inner wall of the cylindrical path 12 in a state including fine water droplets. It will be.

  At this time, the fine particles transported by the air rising in the cylindrical path 12 adheres to the plurality of crushing parts 23 and condenses, and collects at the lower ends of the plurality of crushing parts 23 and easily reliquefies. However, in the present embodiment, the lower part of the upper opening 12a of the cylindrical path 12 is the non-connecting part 28 that does not provide the crushing part 23, so that reliquefaction of fine particles can be suppressed. it can.

  That is, the air volume rising through the gap between the inner wall of the cylindrical path 12 and the outer periphery of the rotating plates 20a to 20c is not uniform, and as it rises in the cylindrical path 12, the upper opening 12a side from the rotary shaft 19 is increased. Therefore, the amount of fine water droplets passing through the upper opening 12a side from the rotary shaft 19 is larger than that in the other part of the air passage in the cylindrical passage 12.

  Therefore, the micronized water droplets passing through the upper opening 12a side of the rotating shaft 19 of the cylindrical path 12 particularly have a lower portion corresponding to the upper opening 12a of the cylindrical path 12, that is, the inner wall of the cylindrical path 12 It is easy to adhere to the unconnected portion 28 and the crushing portion 23.

  Therefore, the lower portion corresponding to the upper opening 12a is not configured to be a non-connecting portion 28 to the inner wall of the cylindrical path 12 of the crushing portion 23, and the crushing portion 23 is also connected to the cylindrical path 12 in this lower portion. If it is set as the structure connected to an inner wall, many fine water droplets which pass the upper opening part 12a side from the rotating shaft 19 of the cylindrical path | route 12 will adhere to the crushing part 23 as mentioned above, and it will condense there and reliquefy. It becomes easy to do.

  On the other hand, since the air volume rising toward the upper opening 12a in the gap on the upper opening 12a side from the rotating shaft 19 of the cylindrical path 12 is larger than the other parts, the crushing part The water droplets obtained by re-liquefying the fine particles adhering to 23 are held there while adhering to the lower end portion of the crushing portion 23.

  And when the water droplet re-liquefied in the crushing part 23 grows further and grows so large that it cannot be maintained even with the warm air blown from below, the water droplet is likely to drop downward due to gravity, and as a result, when the humidifying operation is continued, On the side of the opening 12 a above the rotation shaft 19, a large amount of water droplets from the lower end of the crushing section 23, and the water storage section 26 below the cylindrical path 12 through the gap between the rotating plates 20 a to 20 c and the inner wall of the cylindrical path 12. It will be dripped.

  As described above, if the crushing part 23 is connected to the cylindrical path 12 also on the opening 12a side of the rotary shaft 19, the fine water droplets are easily reliquefied in the crushing part 23. However, in the present embodiment, since the lower part corresponding to the upper opening 12a is the non-connecting part 28 to the cylindrical path 12 of the crushing part 23, the refined particles near the upper opening 12a Reliquefaction can be prevented.

  That is, in the present embodiment, as described above, the lower portion corresponding to the upper opening 12a formed above the outer peripheral surface of the cylindrical path 12 is the non-connecting portion 28 that does not include the plurality of crushing portions 23. Refinement efficiency can be improved by suppressing reliquefaction of the refined water droplets.

  On the other hand, the inner peripheral part of the cylindrical path 12 on the outer periphery of the non-connecting part 28 of the plurality of crushing parts 23 is a connecting part 29 to the inner wall of the cylindrical path 12 of the plurality of crushing parts 23. Since the plurality of crushing portions 23 are configured to be connected at substantially equal intervals, the water droplets scattered by the centrifugal force of the rotating plates 20a to 20c are arranged substantially evenly along the outer periphery of the rotating plates 20a to 20c. In other words, it collides with the collision surfaces 27 of the plurality of crushing parts 23, and as a result, the miniaturization of water is effectively promoted.

  As mentioned above, in this Embodiment, when said liquid refinement | miniaturization apparatus 3 is installed in the sauna chamber 1 and it uses as a sauna apparatus, the rotating plates 20a-20c from the outer periphery of the rotating plates 20a-20c by the centrifugal force of high speed rotation. As a result, the water can be effectively refined by colliding and colliding with the collision surfaces 27 of the plurality of crushing parts 23 at a substantially right angle and being crushed in the tangential direction (A in FIG. 4). As a result, it is possible to increase the water refinement efficiency.

  And since the crushing part 23 is not connected to the cylindrical path | route 12 in the non-connecting part 28 to the cylindrical path | route 12 of the crushing part 23 in the cylindrical path | route 12, it is fine in the upper opening 12a vicinity. The reliquefaction of the liquefied particles can be prevented.

  In addition, by rotating the pumping pipe 22 with the same rotary motor 21 as the rotary plates 20a, 20b, and 20c, the water accumulated in the water storage section 26 is sucked up, and the sucked-up water is exchanged with the upper rotary plate 20a (20b). A horizontally long opening between the lower rotating plate 20b (20c) can supply the rotating plate 20b (20c). As a result, the pumping pipe 22 serves to circulate the pump and supply water to the rotating plate 20b (20c). The water circulation and the water supply to the rotating plate 20b (20c) can be realized with a simple configuration.

  Further, the sucked-up water is ejected from a horizontally long opening (not shown) provided between the upper rotating plate 20a (20b) and the lower rotating plate 20b (20c) to the contact plate 24 provided in an annular shape. Since it can be supplied to the rotating plate 20b (20c) by dropping it, the supplied water can be almost completely refined, and the water that remains slightly in the water storage section 26 and cannot be refined is not discharged. In both cases, it can be dried by the drying operation after the sauna operation is completed, so there is no need for piping construction work to treat the water that could not be refined as wastewater, and as a result, the construction work of the sauna device is simplified.
