JP-A-4-11068

  The problem in the above conventional example is that a drainage path needs to be installed.

  That is, by rotating the rotating plate, a part of the water scattered on the outer periphery of the rotating plate drops down along the inner surface of the atomizing cylinder as a liquid and accumulates below the atomizing cylinder. It is necessary to have a drainage route.

  Since this drainage path is extended from the ceiling to the floor in the sauna room, not only is the construction difficult, but it also impairs the beauty.

  Then, this invention aims at abolishing a drainage path.

  And in order to achieve this object, the present invention comprises an atomizing cylinder arranged in a vertical direction and having an upper opening and a lower opening, a water tray disposed below the lower opening of the atomizing cylinder, A rotating shaft arranged in the vertical direction in the atomizing cylinder, a rotation driving means for the rotating shaft, a plurality of rotating plates arranged at predetermined intervals in the vertical direction of the rotating shaft, and a plurality of rotating plates Among them, water supply means for supplying water onto the upper rotating plate, water collecting means provided on the inner surface of the atomizing cylinder between the plurality of rotating plates, and water collected by the water collecting means downward The collected water supply means to be supplied onto the rotating plate and a blower for ventilating the inside of the atomization cylinder, the blower from the lower opening of the atomization cylinder through the inside of the water tray Air is blown toward the upper opening, and the lower opening of the atomizing cylinder is placed in the water tray. An outwardly protruding portion in the non-opposing portions disposed of, and configured to arrange the water level detection means to the projecting portion, thereby it is to achieve the above object.

  As described above, the present invention is an atomization cylinder that is arranged in the vertical direction and has an upper opening and a lower opening, a water tray disposed below the lower opening of the atomization cylinder, and the inside of the atomization cylinder A rotary shaft arranged in a direction perpendicular to the rotary shaft, a rotation driving means for the rotary shaft, a plurality of rotary plates arranged at predetermined intervals in the vertical direction of the rotary shaft, and the upper of the plurality of rotary plates Water supply means for supplying water onto the rotating plate, water collecting means provided on the inner surface of the atomizing cylinder between the plurality of rotating plates, and water collected by the water collecting means on the lower rotating plate The collected water supply means for supplying air to the atomizing cylinder and a blower for ventilating the inside of the atomization cylinder, the blower from the lower opening of the atomization cylinder through the inside of the water tray to the upper opening The water tray is outside the non-opposing portion of the lower opening of the atomizing cylinder. The protrusion protruding provided, since the construction of arranging the water level detection means to the projecting portion, it is possible to eliminate the drainage path.

  That is, in the present invention, the collecting water means is provided on the inner surface of the atomizing cylinder between a plurality of rotating plates arranged at predetermined intervals in the vertical direction of the rotating shaft, and the collecting water means collects the collecting water means. Since the collected water supply means for supplying water to the lower rotating plate is provided, the water dripping downward along the inner surface of the atomizing cylinder is collected by the collected water means, and then the collected water supply means It can be supplied onto the rotating plate and atomized again with the lower rotating plate.

  For this reason, the quantity of the water dripping at the water receiving tray below the atomization cylinder can be extremely reduced.

  In addition, since the blower of the present invention is configured to blow air from the lower opening of the atomization cylinder toward the upper opening through the water receiving tray, an extremely small amount of water remaining after dripping into the water receiving tray is also obtained. For example, it can be dried by a drying operation after the water atomization operation.

  Furthermore, since the water level detecting means is provided in the water receiving tray, for example, a constant flow rate is not maintained due to an abnormality in the water supplying means, and even when a large amount of water is supplied to the rotating plate, the water receiving tray has accumulated. Abnormal water level can be detected.

  In addition, the water receiving tray is provided with a protruding portion that protrudes outward at a non-opposing portion of the lower opening portion provided in the atomizing cylinder, and the water level detection means is disposed in the protruding portion, so that the air blower from the blower The impact on the water level detection means can be reduced, and as a result, the water level can be accurately detected by the water level detection means, so that even if a water level abnormality occurs, water leakage from the water pan to the outside of the device can be prevented. It can be avoided in advance.

  Therefore, the drainage path installation work that has been necessary in the past is not required, and the workability is improved, and the beauty of the sauna room can be maintained.

And the water channels 11a-11c on a rain gutter are provided as a collection water supply means which supplies the water collected by this water storage part 10a-10c on the lower rotating plates 8b-8d.

  Next, the structure of the air path comprised by the water receiving tray 5, the atomization cylinder 4, and the water receiving tray 5 is demonstrated in detail.

  In the present embodiment, as shown in detail in FIGS. 2A and 2B, the water receiving tray 5 has a bottom surface 12 and an edge portion 13 rising from the outer periphery of the bottom surface 12. As shown in FIG. 1, the upper end is connected to the lower end of the atomizing cylinder 4.

  As shown in FIG. 1, a bottomed cylindrical shape that ventilates between the upper opening 2 and the lower opening 3 provided in the atomization cylinder 4 by connecting the upper end of the water receiving tray 5 to the lower end of the atomization cylinder 4. The air path (solid line A shown in FIG. 1) is formed.

  In the present embodiment, a blower (not shown) is connected upstream of the lower opening 3, the air from the blower is forced to flow into the lower opening 3, and the mist is passed through the water tray 5. The inside of the conversion cylinder 4 is directed upward from below, and the gap between the inner wall of the atomization cylinder 4 and the plurality of rotating plates 8a to 8d, the water storage portions 10a to 10c, and the water channels 11a to 11c is passed, It is set as the structure discharged | emitted from the opening part 2 (solid line A shown in FIG. 1).

  In addition, the lower opening 3 of the atomizing cylinder 4 in the present embodiment has a configuration in which a part of the lower end of the atomizing cylinder 4 is notched as shown in FIG. 1, and the water tray 5 in contact with the lower opening 3. As shown in FIG. 2, the edge portion 13 is provided with a notch 14.

  If it does in this way, it will become the composition into which the air from the said air blower flows in into the water receiving tray 5 through the lower opening part 3 and the notch 14, and the air inflow area to the lower opening part 3 is made into the bottom face 12 of the water receiving tray 5. The structure is expanded downward.

  Further, a groove portion 15 is provided on the bottom surface 12 of the water receiving tray 5 in a direction orthogonal to the air inflow direction from the lower opening 3. The front and back bottom surfaces 12 of the water tray 5 in contact with the groove 15 are configured to be inclined downward toward the groove 15, respectively.

  And in the water receiving tray 5, the protrusion part 16 which protrudes outside is provided in the non-opposing part of the downward opening part 3 of the atomization cylinder 4, As the structure which arrange | positions the float 17 as a water level detection means in this protrusion part 16 Yes.

  Next, the protrusion 16 will be described.

  As shown in FIG. 2, the protrusion 16 in the present embodiment is provided with an opening 18 at a non-opposing portion of the lower opening 3 at the edge 13 of the water tray 5, and the water tray 5 with respect to the opening 18. A rectangular parallelepiped formed by opening the side surface and forming a hollow shape is connected. And the float 17 is arrange | positioned on the lower surface of the protrusion part 16 formed in this rectangular parallelepiped. Furthermore, the lower surface of the protruding portion 16 on which the float 17 is disposed is configured to have substantially the same height as the lower surface of the groove portion 15 provided on the bottom surface 12 of the water receiving tray 5.

  And in the liquid refinement | miniaturization apparatus 1 of this Embodiment, the control part (not shown) which controls each operation | movement of the water supply means 9 shown in FIG. 1, the rotation drive means 7, and the above-mentioned air blower (not shown). 2). And the said control part becomes a structure which controls the operation stop of the said water supply means 9, the said rotation drive means 7, and the above-mentioned air blower (not shown) based on the water level which the float 17 detected. .

  Next, the operation of the water atomization operation of the liquid micronizer 1 in the above configuration will be described.

  In the liquid miniaturization apparatus 1 shown in FIG. 1, when the rotation driving means 7 is driven by a signal from a control unit (not shown), the rotating shaft 6 rotates at high speed inside the atomizing cylinder 4, and the rotating plates 8a to 8b are moved accordingly. It is rotated at high speed.

  At the same time, air is forced to flow into the lower opening 3 of the atomizing cylinder 4 from the blower (not shown) by the signal from the control unit described above, and the inside of the atomizing cylinder 4 is lowered through the water tray 5. Upward from the inner wall of the atomizing cylinder 4, the plurality of rotating plates 8 a to 8 d, the water reservoirs 10 a to 10 c and the water channels 11 a to 11 c, and the discharge discharged from the upper opening 2 of the atomizing cylinder 4 Airflow is generated (solid line A shown in FIG. 1).

  At this time, the water supply means 9 supplies water to the vicinity of the center of the upper surface of the upper rotating plate 8a that rotates at a high speed by a signal from the control unit. The water supplied to the upper surface of the upper rotating plate 8a spreads in the form of a thin film from the vicinity of the center of the rotating plate 8a toward the outer periphery due to the centrifugal force caused by the high speed rotation. It is blown away at high speed from the outer peripheral edge to the outer peripheral direction.

  And most of the water droplets scattered at high speed from the outer edge of the upper rotating plate 8a due to the centrifugal force collide with the inner wall of the atomizing cylinder 4, and the dispersed droplets are crushed by this collision, and the miniaturization is promoted. The

  Further, the water droplets collided with the inner wall of the atomizing cylinder 4 are crushed in the ventilation space between the inner wall of the atomizing cylinder 4 and the rotating plate 8a, and the rotating plate 8a rotating at high speed or the adjacent atomizing It collides with the inner wall of the cylinder 4 again and is crushed, and further refinement of water is further promoted.

  In this way, most of the water supplied from the water supply means 9 to the upper surface of the upper rotating plate 8a is dissipated from the rotating plate 8a rotating at high speed, and collides with the inner wall of the atomizing cylinder 4, and at this point in time. Most of them are miniaturized, and such fine water droplets are transported in a miniaturized state in contact with the above-described updraft (solid line A in FIG. 1).

  On the other hand, among the water droplets scattered by the centrifugal force from the upper rotating plate 8a, a minute amount of water droplets that have condensed after being refined or water droplets that could not be refined are collected by flowing down to the water storage section 10a, and are collected in the water channel 11a. To the upper surface of the lower rotating plate 8b.

  The slight amount of water transported to the rotating plate 8b is also promoted by the high speed rotation centrifugal force of the rotating plate 8b, and the water atomized in the atomizing cylinder 4 or the rotating plate 8b. The water droplets that could not be refined are carried to the upper surface of the lower rotating plate 8c through the water reservoir 10b and the water channel 11a.

  That is, water is collected in the water storage unit 10a, the water storage unit 10b, and the water storage unit 10c as water collecting means, and the lower rotating plate 8b is disposed through the water channel 11a, the water channel 11b, and the water channel 11c as the collected water supply unit. The rotating plate 8c and the rotating plate 8d are re-supplied to the upper surface.

  Thus, in embodiment of this invention, the water supplied to the upper surface of the uppermost rotation board 8a from the water supply means 9 is scattered using the some rotation plates 8a-8d, and is refined | miniaturized. Therefore, the amount of residual water dripping downward under the lowermost rotating plate 8d can be extremely reduced.

  As described above, since there is very little residual water that flows down from the bottom surface 12 of the water receiving tray 5 and accumulates in the groove 15 during the water atomization operation, it flows into the protrusion 16 through the opening 18 provided in the edge 13, Residual water collected on the lower surface of the projecting portion 16 that is configured to be substantially the same height as the lower surface of the groove portion 15 of the water receiving tray 5 is also extremely small. For this reason, the float 17 is maintained at a water level so that it floats slightly from the lower surface of the protrusion 16 at the most.

  Next, the drying operation after stopping the water atomization operation will be described.

  After stopping the water atomization operation, the water supply to the water supply means 9 is stopped by a signal from the control unit (not shown), while the rotation drive of the rotation drive means 7 and the blower ( The inside of the atomization cylinder 4 and the water receiving tray 5 is dried by performing a drying operation that continues a blowing operation by a not-shown) for a certain period of time.

  That is, after the above-described water atomization operation, the entire inside of the atomization cylinder 4 and the water tray 5 is wet. In this state, when a small amount of residual water remains in the water receiving tray 5, the float 17 is maintained at a water level that is slightly lifted from the lower surface of the protruding portion 16, and the normal water level is detected. Based on the water level detected by the float 17, the control unit transmits a signal to the rotation driving means 7 and the blower (not shown), and the rotation driving means 7 is driven to rotate, thereby adhering to the surfaces of the plurality of rotating plates 8 a to 8 d. The water droplets are atomized by centrifugal force, and an air flow (solid line in FIG. 1) that rises in the atomizing cylinder 4 from the lower opening 3 to the upper opening 2 through the water receiving tray 5 by the blower (not shown). Due to A), the liquid is discharged from the upper opening 2 to the outside of the apparatus. Further, since the air flow is blown from the lower opening 3 into the water receiving tray 5, the dried air is attached to the lower surface of the groove portion 15 provided in the direction orthogonal to the air flow and the bottom surface 12 before and after the groove portion 15. Contact with. As a result, vaporization of the remaining water in the water receiving tray 5 is promoted, and an extremely small amount of remaining water remaining in the groove portion 15 of the bottom surface 12 of the water receiving tray 5 can be dried.

  During this time, as the drying in the water tray 5 progresses, the water level detected by the float 17 disposed inside the protrusion 16 gradually falls from the normal water level comparable to that of the water atomization operation, and the drying operation ends. In this case, the water level is almost 0, so that it is naturally dried.

  Thus, even if a very small amount of water remains in the liquid micronizer 1, the residual water can be dried by the drying operation. It becomes unnecessary.

  On the other hand, during the water atomization operation, for example, due to a failure of the water supply means 9, water of a predetermined flow rate or more is supplied to the upper rotating plate 8a and is not atomized by the lower rotating plates 8b to 8d. In this case, in the water receiving tray 5, excess water at a level higher than the normal water level is accumulated in the groove portion 15 of the bottom surface 12. In such a case, the float 17 disposed in the protruding portion 16 detects an abnormality in the water level that flows into the protruding portion 16 through the opening 18 and accumulates on the lower surface of the protruding portion 16, and thereby the control portion (FIG. (Not shown) stops the operation of the water supply means 9, the rotation drive means 7, and the blower (not shown).

  Thus, when the float 17 correctly detects the water level abnormality, the water atomization operation is stopped before water leaks out of the apparatus, for example, from the joint between the upper end of the water receiving tray 5 and the lower end of the atomizing cylinder 4. Thus, it is possible to prevent unexpected situations from occurring.

  As described above, the residual water generated in the liquid atomization apparatus 1 in the water atomization operation is very small, and even if the residual water remains, the float 17 remains in the liquid atomization apparatus 1. Since the normal water level can be correctly detected and dried by the drying operation, and when the water supply means 9 fails, the water level abnormality in the liquid micronizer 1 can be correctly detected. Not only is the waste water treatment in the micronizer 1 unnecessary, but the stability of the operation of the liquid micronizer 1 can be improved.

  That is, since the float 17 is configured to be disposed in the protruding portion 16 that protrudes outward at the non-opposing portion of the lower opening 3, the air blown from the above-described blower (solid line A in FIG. 1) is directly applied to the float 17. It is possible to reduce the indirect influence of causing little influence and flowing into the projecting portion 16 and making the surface of the remaining water undulate. As a result, the water level in the liquid refinement apparatus 1 is reduced by the float 17. Therefore, even if a water level abnormality occurs, water leakage from the water receiving tray 5 to the outside of the apparatus can be avoided in advance.

  With the configuration and operation as described above, in the first embodiment, installation work for the drainage path, which was conventionally necessary, becomes unnecessary, and the workability is improved.

  In addition, since the groove part 15 is provided in the bottom face 12 of the water receiving tray 5, and the said bottom face 12 of the said water receiving tray 5 which contact | connects this groove part 15 is set as the structure which inclines below toward the said groove part, it drips into the water receiving tray 5. A small amount of the remaining water can be collected efficiently.

  Furthermore, since the groove portion 15 is configured to be provided in a direction orthogonal to the air inflow direction from the lower opening 3, in the drying operation after the atomization operation, the air current blown from the above-described blower (solid line A in FIG. 1). However, since the area in contact with the slight residual water accumulated in the groove 15 can be increased, vaporization of the residual water accumulated in the groove 15 can be promoted.

  Further, since the lower surface of the protruding portion 16 is configured to have substantially the same height as the lower surface of the groove portion 15 of the water receiving tray 5, the remaining water accumulated on the lower surface of the groove portion 15 and the lower surface of the protruding portion 16 via the opening 18. As a result, the float 17 can correctly detect the water level of the residual water accumulated in the water receiving tray 5.

  In the first embodiment, the lower opening 3 of the atomizing cylinder 4 has a configuration in which a part of the lower end of the atomizing cylinder 4 is notched as shown in FIG. 5 is provided with a notch 14 so that the opening area into which the air from the blower flows is directed downward toward the bottom surface 12 of the water tray 5 below the atomizing cylinder 4. Since it is enlarged, the opening area into which air flows is increased, and the ventilation resistance can be reduced.

  Furthermore, since it is set as the structure which formed the air inflow port by the lower opening part 3 and the notch 14 of the atomization cylinder 4, the inflow area of the air which flows in from a blower expands below toward the bottom face 12 of the water tray 5 Therefore, the dry air flowing into the atomization cylinder 4 from the blower through the lower opening 3 comes into contact with the bottom surface 12 and the groove 15 of the water tray 5 disposed below the lower opening 3. As the air swirls and an air flow rising to the upper opening 2 is generated, the dry air is further in contact with the water droplets slightly remaining on the surface of the bottom surface 12 and the groove 15 to further promote the evaporation of the remaining water. Is possible.

  The air sucked into the main body case 23 through the suction port 21 shown in FIG. 3 is heated by a large-capacity heat exchanger 24 arranged on the upstream side of the atomizing cylinder 4 and blower 25 in a high temperature dry state. 1 is forced to flow into the lower opening 3 of the atomizing cylinder 4 shown in FIG. 1, and the inner wall of the atomizing cylinder 4 and a plurality of rotations are directed upward from the lower side through the water receiving tray 5. The gaps between the plates 8 a to 8 d, the water reservoirs 10 a to 10 c and the water channels 11 a to 11 c are passed through and are blown toward the upper opening 2.

  Further, in the atomization cylinder 4 shown in FIG. 1, the rotation shaft 6 is rotated at a high speed by the rotation driving means 7, and in this state, water is supplied onto the upper rotating plate 8 a by the water supply means 9.

  Then, water is splashed vigorously from the outer periphery of the upper rotating plate 8a and atomized, and a part of the water collides with the inner surface of the atomizing cylinder 4 and is atomized. It is conveyed by the blower 25 to the warm air flowing from the lower opening 3 to the upper opening 2 of the atomizing cylinder 4, reheated by the heat exchanger 26, and then passed through the exhaust port 22 of the main body case 23 shown in FIG. Then, the steam is supplied from the ceiling exhaust port (not shown) of the sauna room to the sauna room as hot and humid steam.

  Further, returning to FIG. 1, the description will be continued. Water that has collided with the inner surface of the atomizing cylinder 4 but has not been atomized is collected through the water storage portion 10a and then down through the raindrop-shaped water channel 11a. Then, the water is vigorously scattered from the outer periphery of the rotating plate 8b and atomized, and a part of the water collides with the inner surface of the atomizing cylinder 4 and is atomized. The water thus blown is transported to the warm air flowing from the lower opening 3 of the atomizing cylinder 4 toward the upper opening 2 by the blower 25, heated by the heat exchanger 26, and then heated in the main body case 23 shown in FIG. The air is supplied to the sauna room from the ceiling exhaust port (not shown) of the sauna room through the exhaust port 22.

  Thereafter, this repetition is performed by the four-stage rotating plates 8a to 8d, and a sufficient amount of atomized water is supplied into the sauna room together with the hot air. By such an action, in this embodiment, The amount of water dripping down the atomizing cylinder 4 can be extremely reduced.

  During the sauna operation, the float 17 provided on the protrusion 16 flows down from the bottom surface 12 of the water tray 5 and accumulates in the groove 15, and the level of residual water accumulated on the lower surface of the protrusion 16 via the opening 18 is abnormal. Is detected (Step 2).

  At this time, as described above, since the residual water that flows down from the bottom surface 12 of the water receiving tray 5 and accumulates in the groove portion 15 during the sauna operation is extremely small, the lower surface of the protruding portion 16 that is configured to have substantially the same height as the lower surface of the groove portion 15. There is also very little residual water flowing through the opening 18. For this reason, the float 17 is maintained at a water level so that it floats slightly from the lower surface of the protrusion 16 at the most.

  As described above, in a state where no water level abnormality is detected, the sauna operation selected by the user using the remote controller 27 is continued (Step 1).

  Therefore, during the sauna operation, as shown in FIG. 6, the heat exchanger 24, the blower 25, the rotation drive means 7, and the water supply means 9 are all in an operating state.

  On the other hand, during the above-described sauna operation, for example, due to a failure of the water supply means 9, water of a predetermined flow rate or more is supplied to the upper rotating plate 8a and is not atomized by the lower rotating plates 8b to 8d. In the water receiving tray 5, excess water at a level higher than the normal water level is accumulated in the groove portion 15 of the bottom surface 12.

  When such a water level abnormality occurs, the float 17 disposed in the protruding portion 16 detects a water level abnormality on the lower surface of the protruding portion 16 (Step 2), and transmits a signal to the control unit (30 in FIG. 5). A signal is transmitted to the display unit 29 to display the water level abnormality (Step 3).

  On the other hand, a control part (30 of FIG. 5) stops the water supply from the water supply means 9 to the upper rotating plate 8a by outputting to the above-mentioned water supply stop valve and switching to a closed state (Step 4). .

  That is, in a state where water supply from the water supply means 9 to the upper rotating plate 8a is stopped (Step 4), a drying operation (Step 5) for drying the inside of the atomizing cylinder 4 and the water tray 5 is performed. . In this drying operation, while the circulating hot water shutoff valve is in an open state, the hot water circulation to the heat exchanger 24 is continued, the operation of the blower 25 is continued, and the rotation drive of the rotation drive means 7 is continued. .

  Therefore, when the float 17 detects a water level abnormality, as shown in FIG. 6, each of the heat exchanger 24, the blower 25, and the rotation driving means 7 is in an operating state, while the water supply means 9 is in a stopped state. It has become.

  In this drying operation, when a predetermined time, for example, 10 minutes elapses (Step 6), the control unit (30 in FIG. 5) stops the rotation drive of the rotation drive means 7 and stops the operation of the blower 25. And the above-mentioned circulating hot water stop valve is switched to a closed state, and the hot water supply to the heat exchanger 24 and the heat exchanger 26 is stopped (Step 7).

  Then, the water level detected by the float 17 arranged inside the protrusion 16 gradually decreases from the normal water level comparable to that during sauna operation by the above-described drying operation, and when the drying operation ends, the water level becomes almost zero. It is about to dry naturally.

  With the configuration and operation as described above, in the second embodiment, installation work for the drainage path to the sauna room, which has been necessary when using the conventional liquid refinement apparatus for sauna operation, is unnecessary. Becomes better.

  That is, according to the above configuration and operation, the supplied water is atomized by the four-stage rotating plates 8a to 8d, and a sufficient amount of atomized water is supplied as steam into the sauna room, while the atomizing cylinder 4 Since the amount of water dripping down can be extremely reduced, drainage treatment is unnecessary, and the beauty of the sauna room can be maintained.

  As described above, the residual water generated in the sauna device 20 in the sauna operation is extremely small, and the float 17 correctly detects the water level abnormality even if the water supply means 9 fails. Thus, for example, the water supply from the water supply means 9 can be stopped before water leaks out of the apparatus from the joint between the upper end of the water receiving tray 5 and the lower end of the atomizing cylinder 4, so that an unexpected situation occurs. Since the inside of the sauna device 20 can be dried by performing the drying operation for a predetermined time, the drainage treatment of the remaining water in the sauna device 20 becomes unnecessary. In addition, the operational stability of the sauna device 20 can be improved.

  In other words, since the float 17 is arranged in the protruding portion 16 that protrudes outward at the non-opposing portion of the lower opening 3, not only during the sauna operation, but also the drying operation after the float 17 detects a water level abnormality. The float 17 can correctly detect the water level, and as a result, the control unit (30 in FIG. 5) can appropriately control the operation stop of each output destination.

  And since it is set as the structure which operates the large-sized heat exchanger 24 with which the upstream of the atomization cylinder 4 was equipped, and ventilates warm air at the time of the drying operation after detecting a water level abnormality, the temperature in the atomization cylinder 4 Can be increased to increase the amount of saturated water vapor, so that the residual water in the atomizing cylinder 4 can be quickly dried.

  Even in the above-described drying operation, the float 17 is configured to be disposed inside the protruding portion 16 provided in the non-opposing portion of the lower opening 3 of the water tray 5, so that the air blown from the blower 25 is sent to the float 17. Direct influences are reduced, and indirect influences such as the surface of the residual water flowing into the lower surface of the protrusion 16 can be reduced. As a result, the water level in the water tray 5 can be accurately detected by the float 17.

  Thus, not only the efficiency of the drying operation after the normal sauna operation is increased, but even if a water level abnormality occurs, the inside of the apparatus is dried by correctly detecting the water level abnormality by the float 17 and performing the drying operation. In addition, it is possible to avoid water leakage from the water receiving tray to the outside of the apparatus.

  When the water level abnormality is detected by the float 17, the water level abnormality is displayed on the remote controller 27, so that it is possible not only to return to the normal water level by performing the above-described drying operation, but also to the user for the device abnormality. It is possible to inform inspections and repairs.

  Moreover, since it is set as the structure provided with the large-sized heat exchanger 24 as a heating means in the upstream of the atomization cylinder 4, while being able to improve a user's comfort as a sauna apparatus, residual water generate | occur | produces in normal sauna driving | operation Even if it does, since the float 17 can detect the water level of the residual water of the sauna apparatus 20 correctly, if it switches to performing dry operation within predetermined time after sauna operation, the inside of the sauna apparatus 20 will be dried. Therefore, it becomes possible to stabilize the operation of the subsequent sauna operation.

  That is, during the sauna operation, the heat exchanger 24 of FIG. 3 provided on the upstream side of the atomization cylinder 4 is operated to blow the hot air into the atomization cylinder 4, so that immediately after the normal sauna operation is stopped. When the water level abnormality occurs, the temperature of the air in the atomizing cylinder 4 is still high. In such a state, since the sauna operation is switched to the drying operation, the residual heat in the atomization cylinder 4 can be used to efficiently dry the operation.

  In the drying operation described above, the blower 25 is preferably operated in a state in which the blowing capacity is lowered as compared with the sauna operation.

  Specifically, the blower 25 operates in a state in which the blowing capacity is reduced to about half compared to during sauna operation.

  That is, in the second embodiment, as described above, the water dripping downward along the inner surface of the atomizing cylinder 4 is collected by the water storage portions 10a to 10c, and then the lower rotating plates 8b to 8d by the water channels 11a to 11c. Although the atomization effect is enhanced by supplying it above, a large amount of air is blown from the lower opening 3 of the atomizing cylinder 4 toward the upper opening 2 through the water tray 5 by the blower 25 during the drying operation. When drying with wind, the water storage units 10a to 10c and the water channels 11a to 11c have a small amount of remaining water, and the water is dried in the water storage units 10a to 10c and the water channels 11a to 11c. A scale is formed, and when this happens, the subsequent centrifugal atomization of water becomes unstable.

  Therefore, in the second embodiment, the air blower 25 is configured to be operated in a state where the air blowing capacity is lowered as compared with the time of the sauna operation after the normal sauna operation or the drying operation after the water level abnormality occurs. Drying is continued with water flowing from the portions 10a to 10c and the water channels 11a to 11c onto the lower rotating plates 8b to 8d. As a result, scale formation in the water storage portions 10a to 10c and the water channels 11a to 11c is performed. As a result, the subsequent centrifugal atomization of water can be stabilized.

  During the drying operation, the rotation driving means 7 may be operated in a state where the number of rotations is lower than that during the sauna operation, and this can enhance the energy saving effect.

  Furthermore, in this drying operation, the control unit (30 in FIG. 5) is configured to stop the rotation drive of the rotation drive means 7 and stop the operation of the blower 25 and the heat exchanger 24 after a predetermined time has elapsed. Based on the level of residual water detected by the float 17, even when a slight residual water level generated during normal sauna operation accumulates or when an abnormal amount of water accumulates in the water receiving tray 5, It is also possible to perform the drying operation only for the time required for drying in the saucer 5, thereby further enhancing the energy saving effect.

  In the present embodiment, water is supplied from the city water pipe to the water supply means 9 through a water supply stop valve (not shown), but the hot water circulation from the heat source described above is used. It is also possible to provide a water supply stop valve and supply water at a high temperature to the water supply means 9. In this way, the temperature drop due to the vaporizing action in the atomization cylinder 4 is suppressed. As a result, it is possible to prevent the amount of saturated water vapor from being lowered, and it is difficult for residual water in the atomizing cylinder 4 to be generated, and it is possible to dry faster during the drying operation.

  As described above, the present invention is an atomization cylinder that is arranged in the vertical direction and has an upper opening and a lower opening, a water tray disposed below the lower opening of the atomization cylinder, and the inside of the atomization cylinder A rotary shaft arranged in a direction perpendicular to the rotary shaft, a rotation driving means for the rotary shaft, a plurality of rotary plates arranged at predetermined intervals in the vertical direction of the rotary shaft, and the upper of the plurality of rotary plates Water supply means for supplying water onto the rotating plate, water collecting means provided on the inner surface of the atomizing cylinder between the plurality of rotating plates, and water collected by the water collecting means on the lower rotating plate The collected water supply means for supplying air to the atomizing cylinder and a blower for ventilating the inside of the atomization cylinder, the blower from the lower opening of the atomization cylinder through the inside of the water tray to the upper opening The water tray is outside the non-opposing portion of the lower opening of the atomizing cylinder. The protrusion protruding provided, since the construction of arranging the water level detection means to the projecting portion, it is possible to eliminate the drainage path.

  Moreover, not only the drainage path installation work that has been necessary in the past is required, but the workability is improved, and the beauty of the sauna room can be maintained.
