  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 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 rotating plate fixed in the axial direction of the The surface where the upper surface of the plate and the inner surface of the pumping pipe are in contact with each other is composed of a smooth surface having no corners. 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. The air blowing means includes an impeller, a fan motor that rotates the impeller, and a fan casing that contains the impeller, and the cylindrical path is disposed on an outer periphery of the rotating plate. A crushing portion connected to the rotating plate, and the crushing portion forms a collision surface in which a surface facing the rotation direction of the rotating plate protruding toward the rotating shaft is substantially orthogonal to a tangential direction of the rotating plate. The pumping pipe has a substantially cylindrical shape with an opening diameter narrowed toward the bottom, and the rotating plate is composed of a plurality of rotating plates fixed at predetermined intervals in the axial direction of the rotating shaft. Among these multiple rotating plates, the rotating plates other than the topmost plate rotate. The upper surface of the rotating plate and the inner surface of the pumping tube are communicated with each other by having an opening (slit) that is long in the horizontal direction in the connecting portion of the pumping tube, and the opening is shifted in the circumferential direction at each stage of the rotating plate. The water supplied to the rotating plate rotating from the water supply pipe spreads in the outer peripheral direction due to centrifugal force and scatters at a high speed from the outer peripheral edge of the rotating plate and collides with the crushing portion to be refined and refined. The water that did not flow down the inner wall of the cylindrical passage and flows down to the water storage section to be stored, and the water stored in the water storage section is rolled up by the rotation of the pumping pipe, and then upward through the inner surface of the pumping pipe. The above-mentioned object is achieved by moving and ejecting from the opening to the rotating plate and ejecting from the rotating plate in the outer peripheral direction.

  As described above, according to the present invention, the crushing portion connected to the cylindrical path is provided on the outer periphery of the rotating plate, and the crushing portion faces the rotation direction of the rotating plate protruding toward the rotating shaft. The surface constitutes a collision surface that is substantially perpendicular to the tangential direction of the plurality of rotating plates, and the crushing portion crushes the water scattered from the plurality of rotating plates, thereby improving the efficiency of liquid refinement. it can.

  That is, in the present invention, the liquid scattered from the outer edge of the rotating plate due to the centrifugal force is scattered in the substantially tangential direction of the rotating plate and collides with the collision surface of the crushing portion at a substantially right angle, that is, the collision energy is effectively utilized. 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.

  In addition, the pumping pipe has a substantially cylindrical shape with an opening diameter narrowed toward the bottom, so that the amount of water sucked up from the bottom can be controlled to a small amount. Since the centrifugal force can be transmitted, the efficiency of liquid miniaturization can be improved.

  That is, in the present invention, by controlling the amount of water supplied to the rotating plate to a small amount, it becomes possible to form a smaller particle size of the liquid when splashing from the outer edge of the disk, By colliding with the collision surface, the droplets are crushed and the miniaturization is promoted. As a result, the efficiency of the liquid miniaturization is improved.

The liquid refinement apparatus according to claim 1 includes 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, Liquid refinement means provided in the air passage between the blower means and the exhaust port, and the liquid refinement means is arranged 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 at a lower portion of the cylindrical path; A rotary shaft arranged toward the rotary shaft, a rotary motor that rotates the rotary shaft, a pumping pipe that is fixed to the rotary shaft and sucks water from the water storage section, and an outer surface of the pumping pipe, A rotating plate fixed in the axial direction, and The surface of the pumping pipe that is in contact with the inner surface of the pumping pipe is a smooth surface without corners, and the liquid supply means has a water supply pipe for transferring the liquid and a water supply valve arranged in the middle of the water supply pipe. The air blowing means includes an impeller, a fan motor that rotates the impeller, and a fan casing that encloses the impeller, and is connected to the cylindrical path on an outer periphery of the rotating plate. The crushing portion is configured such that a surface facing the rotation direction of the rotating plate protruding toward the rotating shaft constitutes a collision surface substantially orthogonal to a tangential direction of the rotating plate, The pumping pipe has a substantially cylindrical shape with an opening diameter narrowed toward the bottom, and the rotating plate is composed of a plurality of rotating plates fixed at predetermined intervals in the axial direction of the rotating shaft. Among the rotating plates, the rotating plate other than the top is the rotating plate and pumping water. The upper surface of the rotary plate and the inner surface of the pumping pipe are communicated with each other by having an opening (slit) that is long in the horizontal direction in the pumping pipe, and the opening is shifted in the circumferential direction at each stage of the rotary plate, and the water supply The water supplied to the rotating plate rotating from the pipe spreads in the outer peripheral direction by centrifugal force, scatters at a high speed from the outer peripheral edge of the rotating plate, collides with the crushing part, and is refined and not refined. Is stored in the water storage section by flowing down the inner wall of the cylindrical passage, and the water stored in the water storage section is rolled up by the rotation of the pumping pipe and moves upward along the inner surface of the pumping pipe. It has the structure which ejects to the said rotating plate from the said opening part, and it ejects to the outer peripheral direction from the said rotating plate. As a result, the surface where the inner surface of the pumping pipe and the upper surface of the rotating plate are in contact with each other is constituted by a smooth surface having no corners, so that the water rising on the inner surface of the pumping tube moves to the upper surface of the rotating plate without peeling off from the contact surface. Therefore, the rising water moves to the outer edge of the rotating plate where the centrifugal force is most applied and scatters without being separated in the course of the route. The liquid splashed from the outer edge of the rotating plate due to this centrifugal force is scattered in the substantially tangential direction of the rotating plate and collides with the collision surface of the crushing portion at a substantially right angle, that is, the collision energy can be effectively utilized. Dispersed droplets are crushed to promote miniaturization. In addition, since the opening diameter of the pumping pipe is made into a substantially cylindrical shape that narrows toward the bottom, the water sucked up from the bottom can be controlled to a small amount. Since the centrifugal force can be transmitted well, it is possible to make the liquid particle size smaller when splashing from the outer edge of the disk, and the liquid collides with the collision surface, so that the droplets are crushed. Therefore, the effect of improving the efficiency of liquid miniaturization is achieved.

Further, the rotating plate is composed of a plurality of rotating plates fixed at predetermined intervals in the axial direction of the rotating shaft, and the rotating plates other than the uppermost of the rotating plates are the rotating plate and the pumping water. By having a structure in which the upper surface of the rotating plate and the inner surface of the pumping tube are communicated with each other by having a horizontal horizontal opening (slit) in the pumping pipe at the connection point of the pipe, Since the water is distributed and distributed to each rotating plate, the amount of water supplied to each rotating plate is further reduced, and the centrifugal force can be efficiently transmitted to the small amount of supplied water on the rotating plate. It is possible to reduce the particle size of the liquid when splashing from the outer edge of the liquid, and the liquid collides with the collision surface, so that the liquid droplets are crushed and the miniaturization is promoted. There is an effect of improving.

  Furthermore, when the position of the opening is provided at the same position in the circumferential direction, the water that has moved upward along the inner wall of the pumping pipe is ejected from the first opening, and the water does not rise to the upper opening, The amount of water discharged from each rotating plate is biased. Therefore, in order to uniformly disperse the amount of water discharged from each rotating plate, the position of the opening is shifted in the circumferential direction.

Moreover , the said cylindrical path | route is ventilated by the said ventilation means from the said lower opening part toward the said upper opening part through the clearance gap between the inner wall of the said cylindrical path | route, the said crushing part, and the said rotating plate. It may be. As a result, in the cylindrical path, the direction in which the fine water droplets fall and the wind direction become countercurrent, and as a result, the contact time between the water droplets and the ventilation increases, so vaporization is promoted even for large-diameter water droplets. Since the shape is changed into fine water droplets, there is an effect of improving the efficiency of liquid miniaturization .

Alternatively , the auxiliary heating means may be provided between the upper opening of the cylindrical path of the liquid micronization means and the exhaust port. As a result, in the path after discharging the liquid refinement means, the heat is added to the water droplets existing in a large-diameter shape, and vaporization is promoted to change the shape into fine water droplets. There is an effect of improving the efficiency of miniaturization.

  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.

  In the present embodiment, the liquid refinement means 9 is provided between the fan motor 8 and the exhaust port 5, but the configuration is not particularly limited as long as a sufficient humidification amount and air volume can be obtained. Even if the fan motor 8 is provided between the liquid miniaturization means 9 and the exhaust port 5, no difference is produced in its function and effect.

  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 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 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 26 of the crushing part 23 at a substantially right angle, the dispersed droplets are effectively crushed by this collision, and miniaturization is promoted.

  In addition, the water droplets collided with the collision surface 26 scatter in the gaps between the cylindrical path 12 and the plurality of crushing portions 23 and the rotating plates 20a to 20c, and adjacent to the rotating plates 20a to 20c that rotate 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 surface 26 of the plurality of crushing parts 23 or the inner wall 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 along the inner wall of the cylindrical path 12 and are stored in the water storage unit 25.

  At this time, the pumping pipe 22 is rotating above the water storage unit 25, and when the amount of water stored in the water storage unit 25 increases and the water surface approaches the lower end of the water pumping tube 22, the water storage in the water storage unit 25 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 a substantially cylindrical shape with an opening diameter narrowing toward the bottom as described above, a suction force works inside. For this reason, the water stored in the water storage unit 25 is rolled up together with the air on the water surface, and moves upward along the inner wall of the pumping pipe 22. At this time, since the opening diameter of the pumping pipe 22 is a substantially cylindrical shape that narrows toward the bottom portion, the water sucked up from the bottom portion can be controlled to a small amount, and the rotating plate 20a is added to this small amount of supply water. Since it becomes possible to transmit centrifugal force efficiently on (20b, 20c), it becomes possible to form a smaller particle size of liquid when splashing from the outer edge of the rotating plate 20a (20b, 20c). Since the liquid collides with the collision surface 26, the liquid droplets are crushed and the miniaturization is promoted, so that the efficiency of the liquid miniaturization is improved.

  And the water which moved upwards along the inner wall of the pumping pipe 22 is the rotating plate 20b and the rotating plate 20c through the horizontally long opening 24 at the connecting portion of the rotating plate 20b and the rotating plate 20c and the pumping pipe 22. Further, the water spread in the form of a thin film toward the outer peripheral direction due to the centrifugal force due to the high-speed rotation, and the water in the form of the thin film is high-speed in the tangential direction (A shown in FIG. 4) from the outer peripheral edge of the rotary plate 20b Is blown away. At this time, the surface where the inner surface of the pumping pipe 22 and the upper surface of the rotary plate 20a (20b, 20c) are in contact with each other is constituted by a smooth surface having no corners, so that the water rising on the inner surface of the pumping pipe 22 is separated from the contact surface. Without moving, the rising water moves to the outer edge of the rotating plate 20a (20b, 20c) to which the most centrifugal force is applied and scatters without moving to the upper surface of the rotating plate 20a (20b, 20c).

  Thus, the water droplets scattered by the centrifugal force collide with the collision surfaces 26 of the plurality of crushing portions 23 substantially orthogonal to the tangent line of the rotating plate 20a (20b, 20c) to promote 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.

  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 the position of the horizontally long opening (not shown) provided at the connecting portion of the rotating plate 20b, the rotating plate 20c and the pumping pipe 22 is provided at the same position in the circumferential direction, The water that has moved upward along the inner wall is ejected from the first opening (not shown), and the water does not go up to the upper opening (not shown), so that each rotating plate 20a, rotating plate 20b, The amount of water discharged from the rotating plate 20c is biased. Therefore, the positions of the openings (not shown) are shifted in the circumferential direction in order to uniformly disperse the amount of water discharged from each rotating plate.

  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 26 of the plurality of crushing parts 23 and the inner wall of the cylindrical path 12 and is fine. 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, A minute amount of water droplets condensed on the inner wall after being miniaturized, flows along the inner wall of the cylindrical path 12, flows down to the water storage unit 25, and is 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.

  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 colliding with the collision surfaces 26 of the plurality of crushing parts 23 by high-speed rotation of the rotating plates 20a to 20c maintain a 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.

  As mentioned above, in this Embodiment, when said liquid refinement | miniaturization apparatus 3 is installed in the sauna chamber 1 and utilized as a sauna apparatus, the surface which contact | connects the inner surface of the pumping pipe 22 and the upper surface of rotary plate 20a (20b, 20c) is a corner. Since the water rising on the inner surface of the pumping pipe 22 moves to the upper surface of the rotating plate 20a (20b, 20c) without peeling from the contact surface, the rising water is separated in the middle of the path. Without moving, it moves to the outer edge of the rotating plate 20a (20b, 20c) to which the centrifugal force is most applied and scatters. The liquid splashed from the outer edge of the rotating plate 20a (20b, 20c) by this centrifugal force is scattered in the substantially tangential direction of the rotating plate 20a (20b, 20c) and collides with the collision surface 26 of the crushing portion 23 at a substantially right angle. In other words, since the collision energy can be used effectively, the liquid droplets diffused by the collision are crushed and the miniaturization is promoted. Moreover, since the opening diameter of the pumping pipe 22 is made into the substantially cylindrical shape which became narrow toward the bottom part, it has the structure which can control the water sucked up from a bottom part to a small quantity, and the rotating plate 20a ( 20b, 20c), it is possible to efficiently transmit centrifugal force, so that it is possible to make the particle size of the liquid smaller when splashing from the outer edge of the disk, and this liquid collides with the collision surface 26. By doing so, the droplets are crushed and the miniaturization is promoted, so that the efficiency of the liquid miniaturization is improved.

  According to such a configuration, the supplied water can be almost completely refined, and the drying operation after the sauna operation is completed without draining the water that remains slightly in the water storage unit 25 and cannot be refined. Therefore, there is no need for piping construction for treating the water that could not be refined as wastewater, and as a result, the sauna construction work can be simplified.

  As described above, the present invention includes a main body case having a suction port and an exhaust port, a heating unit and a blowing unit provided in an air passage connecting the suction port and the exhaust port in the main body case, and the blowing unit. Liquid refinement means provided in the air passage between the exhaust ports, the liquid refinement means is disposed in a vertical direction, and has a cylindrical path having an upper opening and a lower opening, and the tubular shape A rotation means provided in the path, a liquid supply means for supplying a liquid to the rotation means, and a water storage part provided at a lower portion of the cylindrical path, and the rotation means is directed in the vertical direction.
