JP-A-4-11068

  The problem with the above conventional example is that it takes a long time to dry the inside of the apparatus after operation.

  That is, as described above, the conventional liquid micronizer supplies a constant amount of liquid to the upper surface of the rotating disk, but the amount of humidification varies depending on the temperature and humidity of the intake air, and so is not humidified. Of course, the amount of water returned to the tank also changes. In order to stably humidify, it is necessary to keep a sufficient amount of water in the tank in consideration of variations in the amount of liquid supplied in the liquid supply stage and variations in the amount of humidification in the liquid refinement means. On the other hand, it is necessary to dry the inside of the apparatus after operation in order to suppress the growth of bacteria. Accordingly, the present invention detects the amount of water stored in the water storage unit to the minimum necessary, shortens the drying time when drying the apparatus, and further detects whether there is a problem with the constant supply of liquid at the minimum necessary amount.

When it is recognized, a water supply abnormality determining means for reporting an abnormality is provided, and a drying operation for drying the liquid remaining in the water storage unit is performed after the refining operation for refining the liquid stored in the water storage unit is completed. The above-described object is achieved by using a liquid micronizer.

  As described above, the present invention determines the inundation state of the first water level and the second water level based on the temperatures detected by the first and second temperature detecting means and the air path temperature detecting means, and the liquid Since the opening and closing of the supply means is controlled, the amount of water stored in the liquid refinement means can be adjusted, and the amount of water stored in the water storage section can be minimized.

  The basic concept for controlling the opening and closing of the liquid supply means is as follows. The first and second temperature detecting means and the air path temperature detecting means are arranged in the air path. When the heating means and the air blowing means are driven in a state where there is no water in the water storage section, the temperatures detected by the first and second temperature detecting means and the air path temperature detecting means rise and show substantially the same temperature. On the other hand, if water is stored in the water storage section, the temperature detected by the first temperature detection means and / or the second temperature detection means is lower than the temperature detected by the air path temperature detection means, It is determined that the water has been submerged to the first water level or the second water level. The opening and closing of the liquid supply means is controlled by the detected water level.

  Thereby, the retention amount of the stored water in the liquid refinement means can be adjusted, and the amount of water stored in the water storage unit can be minimized. And after completion | finish of refinement | miniaturization operation, the liquid supply means is closed, and the drying time at the time of performing the drying operation which applies warm air to the remaining water of a water storage part in the state which does not supply a liquid can be shortened. Furthermore, since there is no residual water in the liquid micronizer after the drying operation, there is no need for a drain pipe, and the construction work when the liquid micronizer is installed can be easily performed. . Also, by providing a water supply abnormality determining means for reporting an abnormality when recognizing that there is a problem with the liquid supply means and water is not being supplied, it is possible to always respond to abnormalities in the liquid supply means. Prompt response to defects is possible.

  In addition, the liquid water supply determining means has a temperature detected by the air path temperature detecting means (hereinafter referred to as air path temperature) higher than a predetermined temperature Tw, and a temperature detected by the air path temperature and the second temperature detecting means. (Hereinafter, the second water level temperature) is larger than the predetermined temperature difference ΔTa, and the temperature difference between the second water level temperature and the temperature detected by the first water level detecting means (hereinafter, the first water level temperature) is When the temperature difference is smaller than the predetermined temperature difference ΔTb, the liquid level is determined to be submerged to the first level, and the liquid supply means is closed to stop the water supply.

  Thereby, it can be determined that the liquid water level has been submerged to the first water level, the amount of stored water in the liquid refinement means can be adjusted, and the amount of water stored in the water storage section is the minimum required. It can be. And after completion | finish of refinement | miniaturization operation, there exists an effect that it becomes possible to shorten the drying time at the time of performing the drying operation which closes a liquid supply means and applies warm air to the residual water of a water storage part in the state which does not supply a liquid. .

  Further, when the temperature difference between the first water level temperature and the second water level temperature is larger than the predetermined temperature difference ΔTc, the liquid water supply determining means is that the liquid water level is not immersed in the first water level. It has the structure which judges and opens a liquid supply means and supplies water.

  Thereby, it can be determined that the liquid water level is not submerged in the first water level, the amount of water stored in the liquid refinement means can be adjusted, and the amount of water stored in the water storage part is the minimum required. Limit. And after completion | finish of refinement | miniaturization operation, there exists an effect that it becomes possible to shorten the drying time at the time of performing the drying operation which closes a liquid supply means and applies warm air to the residual water of a water storage part in the state which does not supply a liquid. .

  In addition, the liquid water supply determining means determines that the liquid level is higher when the air path temperature is higher than the predetermined temperature Tw and the temperature difference between the air path temperature and the second water level temperature is smaller than the predetermined temperature difference ΔTa. The second water level is determined not to be submerged, and the liquid supply means is opened to supply water.

  Thereby, it can be determined that the liquid water level is not submerged in the second water level, the amount of water stored in the liquid refining means can be adjusted, and the amount of water stored in the water storage part is the minimum required. Limit. And after completion | finish of refinement | miniaturization operation, there exists an effect that it becomes possible to shorten the drying time at the time of performing the drying operation which closes a liquid supply means and applies warm air to the residual water of a water storage part in the state which does not supply a liquid. .

  In addition, the liquid water supply determination unit is configured such that when the heating unit is not driven, the air path temperature is lower than a predetermined temperature Tw, and the temperature difference between the second water level temperature and the first water level temperature is a predetermined temperature. When the difference is smaller than ΔTb, the liquid supply means is closed to stop water supply.

  Thereby, it can be determined that the liquid water level may have been submerged to the first water level, the amount of retained water in the liquid refining means can be adjusted, and the amount of water stored in the reservoir Can be minimized. And after completion | finish of refinement | miniaturization operation, there exists an effect that it becomes possible to shorten the drying time at the time of performing the drying operation which closes a liquid supply means and applies warm air to the residual water of a water storage part in the state which does not supply a liquid. .

  Further, in a state where the liquid water supply means is open, the water supply abnormality determining means is configured such that the air passage temperature is higher than a predetermined temperature Tw and the temperature difference between the air passage temperature and the second water level temperature is a predetermined temperature difference ΔTa. In a case where the predetermined time t2 elapses in a smaller state, the liquid supply unit is recognized and notified.

  As a result, under normal water supply conditions, it is possible to determine that there is some water supply abnormality because it is not possible to detect inundation at the second water level that should detect inundation after some time has passed. Is possible.

  Moreover, it has the structure which used the thermistor as said 1st, 2nd temperature detection means and said air path temperature detection means.

  Thereby, it is possible to adjust the amount of retained water in the liquid refining means with a simple configuration, and to minimize the amount of water stored in the reservoir. And after completion | finish of refinement | miniaturization operation, there exists an effect that it becomes possible to shorten the drying time at the time of performing the drying operation which closes a liquid supply means and applies warm air to the residual water of a water storage part in the state which does not supply a liquid. .

The humidifying means includes a liquid refinement means case having an upstream opening and a downstream opening, a rotation means provided in the liquid refinement means case, the rotation means includes a rotation motor, and the rotation motor. It is composed of a pumping pipe that is fixed and sucks water from the water storage section, and a rotary plate that is fixed to the outer peripheral surface of the pumping pipe and has a rotating surface that is substantially orthogonal to the rotating shaft of the pumping pipe, The pump is rotated by driving the rotary motor to suck up the liquid in the reservoir, and the sucked up liquid is blown in the outer circumferential direction along the rotating surface of the rotating plate,
The liquid is refined and humidified.

  The liquid refining means is that the liquid splashed from the outer edge of the rotating plate due to 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. As a result, the liquid droplets diffused by the collision are crushed and the miniaturization is promoted.

  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. Miniaturization is promoted.

  Thereby, the retention amount of the stored water in the liquid refinement means can be adjusted, and the amount of water stored in the water storage unit can be minimized. And after completion | finish of refinement | miniaturization operation, there exists an effect that it becomes possible to shorten the drying time at the time of performing the drying operation which closes a liquid supply means and applies warm air to the residual water of a water storage part in the state which does not supply a liquid. .

(Embodiment 1)
FIG. 1 is a perspective view of a sauna apparatus using a liquid micronizer according to an embodiment of the present invention. As shown in FIG. 1, a liquid micronizer 3 is provided on a ceiling surface 2 of a sauna room 1. It is attached.

An eliminator 23 that removes large-diameter water droplets is provided upstream of the auxiliary heat exchanger 11.

  As shown in FIG. 2, the liquid refinement means 9 includes a liquid refinement means case 12 having an upstream opening 12a and a downstream opening 12b, a rotation means 13 provided inside the liquid refinement means case 12, A water supply pipe 14 is provided as a liquid supply means for supplying water to the rotating means 13.

  A constant flow valve 15 is provided in the water supply pipe 14, and a water supply valve 17 is provided in an upstream pipe 16 of the constant flow valve 15.

  The rotating means 13 has a rotating shaft 19 arranged in the vertical direction, and a plurality of rotating plates 20 a and 20 b that rotate about the rotating shaft 19 are vertically arranged at predetermined intervals in the axial direction of the rotating shaft 19. It is fixed. In the present embodiment, the rotary plate 20a, the rotary plate 20b, and two rotary plates are provided from the upper side to the lower side of the rotary shaft 19.

  A rotating motor 21 for driving the rotating shaft 19 is provided at the upper part of the rotating means 13, and an inverted conical pumping pipe formed integrally with the rotating plate 20a and the rotating plate 20b at the lower part of the rotating means 13. 22 is provided. That is, the pumping pipe 22 has a conical shape with the narrow end side as the suction port 22a, and is provided with the suction port 22a facing down.

  Further, as shown in FIG. 3, the pumping pipe 22 is provided with two horizontally long openings 24 through which the pumped water is ejected by a centrifugal force by rotation at a place where each rotary plate 20 b and the pumping pipe 22 are connected. The position of the opening 24 is shifted in the circumferential direction so that the direction in which water is ejected differs between the rotating plates.

  Further, as shown in FIG. 2, a water reservoir 25 is provided at the bottom of the liquid refinement means case 12. And the shape where the bottom part of the water storage part 25 becomes narrow, for example, the shape of an inverted trapezoid, or the shape of a bowl is made so that the amount of water that cannot be pumped by the pumping pipe 22, that is, the amount of water stored at the end of the refining operation is reduced. Good.

  The first water level is located at the lowermost part of the pumping pipe 22, that is, above the suction port 22a of the humidifying means, and can hold the minimum amount of water required by the humidifying means, for example, 2 mm above the suction port 22a. Set. As means for detecting the first water level, a first thermistor 26 (first temperature detecting means) is provided. The first water level is a position where the water surface is slightly above the suction port 22a of the pumping pipe 22. That is, it is set, for example, about 2 mm above the suction port 22 a of the water pump 22.

  Then, the second water level is set at a position below the lowermost part of the pumping pipe 22, that is, below the suction port 22 a of the humidifying means and serving as the bottom of the water storage unit 25. As a means for detecting this second water level, a second thermistor 27 (second temperature detecting means) is provided.

  Further, a third thermistor 33 (air path temperature detecting means) is provided in the air path 50 on the downstream side of the heat exchanger 7.

  Next, the configuration of the control means 28 will be described with reference to FIG.

  The control means 28 includes a remote controller 30 having a display unit and a driving operation switch (not shown), a first thermistor 26, a second thermistor 27, a third thermistor 33, and a water supply valve 17 based on signals from each thermistor. The liquid supply determining means 34 for determining whether to open or close the liquid supply means and the water supply abnormality determining means 35 for reporting an abnormality to the display unit when it is recognized that water has not been supplied due to a problem in the liquid supply means.

  The control unit 29 drives the pump that supplies hot water to the heat exchanger 7, the fan motor 8, the rotary motor 21 that drives the rotary shaft 19, and the water supply valve 17 based on the operation signal from the remote controller 30 and the signal of each thermistor. I have control.

  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. Further, until the rotary motor 21 is driven, it is stopped by the water supply valve 17 and is not discharged from the water supply pipe 14.

  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 air inlet 4, and the sucked air is absorbed by the heat exchanger 7. Heated. The heated air is sent by the fan motor 8 to the liquid refinement means case 12 via the fan casing 10.

  On the other hand, when the rotary motor 21 is driven, the rotary shaft 19 rotates at a high speed, and accordingly, the rotary plate 20a and the rotary plate 20b are rotated at a high speed.

  At this time, the water supply pipe 14 supplies water at a flow rate set by the constant flow valve 15 and stores the water in the water storage unit 25. On the other hand, the pumping pipe 22 is rotating above the water reservoir 25. 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, that is, the suction port 22a of the water pumping tube 22, the water stored in the water storage unit 25 is rolled up together with the air on the water surface. It moves upward along the inner wall of the tube 22.

  This action occurs because the pumping pipe 22 has an inverted conical shape as described above, and a suction force is applied to the inside. For this reason, the water stored in the water storage section 25 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 24 by centrifugal force due to rotation, transmitted to the rotating plate 20b, and thinned toward the outer periphery by centrifugal force due to high-speed rotation. spread. The water in the form of a thin film is blown off at high speed from the outer peripheral edge of the rotating plate 20b in the tangential direction.

  Then, the water droplets scattered by the centrifugal force collide with the inner wall of the liquid refinement means case 12 and are crushed, thereby promoting the water refinement.

  Further, the water that has moved upward along the inner wall of the pumping pipe 22 and has not been ejected from the opening 24 rises further along the inner wall of the pumping pipe 22, and is formed into a thin film toward the outer periphery by centrifugal force due to high-speed rotation. spread. The water in the form of a thin film is blown off at high speed from the outer peripheral edge of the rotating plate 20a in the tangential direction.

  Then, the water droplets scattered by the centrifugal force collide with the inner wall of the liquid refinement means case 12 and are crushed, thereby promoting the water refinement.

  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.

  Thus, almost all of the water pumped by the pumping pipe 22 is refined, mixed with the heated warm air, becomes steam, and is discharged from the upper opening. However, some of the water droplets are not finely adhered to the inner wall of the liquid micronizing means case 12 or a minute amount of water droplets condensed on the inner wall after being miniaturized, and travel along the inner wall of the liquid micronizing means case 12. Then, it 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 rotating plate 20 a and the rotating plate 20 b is supplied as steam from the exhaust port 5 to the inside of the sauna room 1 by blowing air from the fan motor 8.

  At this time, the amount of water supplied from the water supply pipe 14 becomes a problem in order for the water pumped up by the water supply pipe 22 to be almost completely refined. That is, the amount of water that can be refined is set by the micronization capability of the liquid micronizer 9 determined by the number of rotating plates 20a and 20b, the number of rotations of the rotary motor 21, and the like, and is, for example, 45 cc / min.

  On the other hand, since the constant flow valve 15 varies in flow rate depending on the water temperature and water pressure, a buffer function is provided for the amount of water stored in the water storage unit 25 and the amount of water pumped in the pumping pipe 22. For example, when 45 cc / min or more is supplied from the constant flow valve 15, the initial water storage amount increases. On the other hand, since the amount of refined water (pumped water) also increases, the amount of water supplied from the constant flow valve 15 and the amount of refined water are substantially the same in a steady state.

  That is, during normal sauna operation, in a steady state, the amount of water supplied from the constant flow valve 15 and the amount of refined water are substantially the same, and the humidification amount to the sauna chamber 1 is also stable.

  However, the humidification amount to the sauna room 1 is assumed when the sauna room 1 is low humidity. For example, when the sauna room 1 is highly humid, such as when the sauna is operated during bathing, the above-mentioned supply water amount is It exceeds the amount of fine water. One feature of the present embodiment is that the liquid supply determination means 34 intermittently controls the opening and closing of the water supply valve 17 so that the amount of supplied water does not become excessive.

  The principle of determination of the water level in the liquid supply determination unit 34 will be described. During the sauna operation, the temperature of the air that has passed through the heat exchanger 7 is high, and the surroundings of the water reservoir 25 (the air passage 50) are in a high temperature state. Therefore, the temperature difference between the temperature of the air passage 50 and the supplied water (that is, the water temperature of the water storage unit 25) increases. Using this principle, it is determined whether water has accumulated up to the first water level (the position of the first thermistor 26) and the second water level (the position of the second thermistor 27).

  The five determinations in the liquid supply determination unit 34 will be specifically described.

In the first determination, when the following three conditions are met, it is determined that the liquid level of the water storage section 25 is submerged to the first level, and the water supply valve 17 is closed to stop water supply. That is, the water supply is stopped when the suction port 22a of the pumping pipe 22 is at a water level at which water can be sucked up.
1) The temperature detected by the third thermistor 33 (that is, the temperature of the air passage 50. Hereinafter, the air passage temperature) is higher than the predetermined temperature Tw.
2) The temperature difference between the air path temperature and the temperature detected by the second thermistor 27 (that is, the temperature of the second water level in the water storage section 25. Hereinafter, the second water level temperature) is larger than the predetermined temperature difference ΔTa.
3) The temperature difference between the second water level temperature and the temperature detected by the first thermistor 26 (that is, the temperature of the first water level in the water storage unit 25. Hereinafter, the first water level temperature) is smaller than the predetermined temperature difference ΔTb.

In the second determination, when the following conditions are satisfied, it is determined that the liquid level of the water storage section 25 is not submerged to the first water level, and the water supply valve 17 is opened to supply water. That is, the water supply is started when the suction port 22a of the pumping pipe 22 cannot absorb water, or when the water level of the pumping pipe 22 cannot absorb water when the water level drops a little further.
1) The temperature difference between the first water level temperature and the second water level temperature is larger than a predetermined temperature difference ΔTc.

In the third determination, when the following two conditions are satisfied, it is determined that the liquid level of the water storage section 25 has not reached the second water level, and the water supply valve 17 is opened to supply water. That is, there is almost no water in the water reservoir 25.
1) The air path temperature is higher than the predetermined temperature Tw.
2) The temperature difference between the air passage temperature and the second water level temperature is smaller than the predetermined temperature difference ΔTa. The fourth judgment is that when the following three conditions are met, the water level of the liquid in the reservoir 25 is It is determined that the water level has been reached, and the water supply valve 17 is closed to stop water supply.
1) The heat exchanger 7 is not driven (not passing hot water)
2) The air path temperature is lower than the predetermined temperature Tw.
3) The temperature difference between the second water level temperature and the first water level temperature is smaller than the predetermined temperature difference ΔTb. The fifth judgment is that when the following three conditions are met, the water level of the liquid in the reservoir 25 is It is determined that the water level has not reached one, and the water supply valve 17 is opened to supply water 1) The heat exchanger 7 is not driven (warm water is not passed through).
2) A predetermined time t1 has elapsed since the water supply valve 17 was closed.
3) The temperature difference between the first water level temperature and the second water level temperature is larger than the predetermined temperature difference ΔTb.

  Next, opening / closing control of the water supply valve 17 will be described with reference to the flowchart of FIG.

  As shown in FIG. 5, during normal sauna operation, hot water is passed through the heat exchanger 7, the fan motor 8 and the rotary motor 21 are operated, and the water supply valve 17 is opened (S0).

  Here, during normal sauna operation, the temperature (airway temperature) detected by the third thermistor 33 is 60 ° C. or higher.

  The temperature of the supplied water is low, and when the first thermistor 26 and the second thermistor 27 are submerged, the temperature detected by the first thermistor 26 (first water level temperature), the second The temperature (second water level temperature) detected by the thermistor 27 is approximately 40 ° C. or lower when the air passage temperature is about 60 ° C. and tap water is used as water for water supply. On the other hand, when the first thermistor 26 and the second thermistor 27 are not submerged, the temperature is substantially the same as the air path temperature.

  After S1, the liquid water supply determining means 34 controls the opening and closing of the water supply valve 17 according to the first water level temperature, the second water level temperature, the air path temperature, and the operation state (water flow state) of the heat exchanger 7.

  When the temperature in the sauna room 1 is lower than the target temperature, the water passage to the heat exchanger 7 is continued, so the temperature around the water storage unit 25 is high and the temperature difference from the supplied water is large. Can be judged clearly. In that case, the air is sufficiently warmed and the air path temperature is high (for example, 60 ° C. or more), and the temperature difference between the temperature of the supplied water and the heated air can be clearly determined. Further, when the second thermistor 27 is submerged, the temperature difference between the air passage temperature and the second water level temperature becomes large (for example, 10 ° C. or more). Further, since the pumping pipe 22 is rotated and agitated, the temperature of the stored water in the water storage unit 25 becomes substantially uniform.

That is, when the airway temperature is high (eg, 60 ° C. or higher), the temperature difference between the airway temperature and the second water level temperature is large (eg, 10 ° C. or higher), and the temperature difference between the second water level temperature and the first water level temperature is small. Since it can be determined that the first thermistor 26 has been submerged (for example, less than 2 ° C.), the water supply valve 17 is closed. (S1)
Thereafter, when the temperature difference between the first water level temperature and the second water level temperature is large (for example, 5 ° C. or more), it is determined that the second thermistor 27 is submerged, but the first thermistor 26 is not submerged. Therefore, the water supply valve 17 is opened. (S2)
Normally, the above conditions are alternately set to control the opening and closing of the water supply valve 17, but the water flow of the heat exchanger 7 may be stopped for a long time, such as when the temperature setting is greatly lowered after a long time of high-temperature operation. When the water supply valve 17 continues to be closed, the second thermistor 27 disposed at the bottom of the water storage unit 25 may be dried. At this time, the first water level temperature, the second water level temperature, and the air path temperature are substantially uniform. In that case, since the air path temperature is high (for example, 60 ° C. or more) and the temperature difference between the air path temperature and the second water level temperature is small (for example, less than 10 ° C.), the second thermistor 27 is not submerged. The water supply valve 17 is opened and water is supplied. (S3)
Moreover, since the water flow to the heat exchanger 7 is stopped when the temperature in the sauna room 1 is higher than the target temperature, the temperature around the water storage unit 25 is lowered, and the temperature difference from the supplied water is reduced. In that case, since the air passage temperature is low (for example, less than 60 ° C.) and the temperature difference between the second water level temperature and the first water level temperature is small (for example, less than 2 ° C.), the first thermistor 26 is submerged. There is a possibility that the water supply valve 17 is closed. (S4)
Further, when a predetermined time t1 (for example, 4 minutes or more) has elapsed since the water supply valve 17 was closed, normally, the water in the water storage unit 25 is used for humidification, and the first thermistor 26 is submerged. There should be no. Therefore, when a predetermined time t1 (for example, 4 minutes or more) has passed since the water supply valve 17 was closed and the temperature difference between the first water level temperature and the second water level temperature is large (for example, 2 ° C. or more), the first The thermistor 26 opens the water supply valve 17 because there is a possibility that the thermistor 26 is not flooded. (S5)
With the above control, the water level can be adjusted even when the heat exchanger 7 is not passing water.

  Next, the water supply abnormality determination means 35 will be described based on the flowchart of FIG.

During normal sauna operation, warm water is passed through the heat exchanger 7, the fan motor 8 and the rotary motor 21 are operated, and the water supply valve 17 is opened. In a state in which the water supply valve 17 is open, water supply to the water storage unit 25 starts in a normal state. Therefore, the second thermistor 27 is submerged when a certain period of time has elapsed, and a high airway temperature (for example, 60 ° C. or higher). ) And the second water level temperature should be large (eg, 10 ° C. or more). That is, the temperature difference between the air passage temperature and the second water level temperature remains small (for example, 10 minutes) while a predetermined time t2 (for example, 10 minutes or more) has elapsed since the sauna operation was started and the water supply valve 17 was opened. If the temperature is kept below (° C.), it is determined that there is some abnormality in the water supply path and the water supply is not correct, and the abnormality in the water supply is reported to the display unit. In addition, the operation of the apparatus is stopped simultaneously with the notification. That is, water is supplied to the heat exchanger 7, the operation of the fan motor 8 and the rotary motor 21 is stopped, and the water supply valve 17 is closed. (E1)
With the control described above, it is possible to detect any abnormality that occurs in the water supply path, and it is possible to quickly respond to product defects.

  In this embodiment, the temperature of the supplied water is low. However, considering the generation of bacteria and the humidification efficiency, even if hot water (for example, 70 ° C. or higher) is supplied, the effect is not achieved. no problem. This is because even if high-temperature hot water is supplied, the temperature of the water retained in the water storage unit 25 is approximately 40 ° C. or less due to the influence of heat transfer to the housing and the latent heat of vaporization.

  In addition, here, the heat exchanger 7 and the auxiliary heat exchanger 11 are provided as the heating means. However, the heating means is not limited to this as long as it is means for heating air, and there is a problem even if an electric heater or the like is used. There is no. Further, regarding the positional relationship including the heating unit, it is important that the positional relationship is provided upstream of the liquid micronization unit 9, so that the positional relationship does not depend on the configuration of the present embodiment. There is no problem.

  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 amount of liquid refinement | miniaturization in a liquid refinement | miniaturization means is carried out by opening and closing a water supply valve intermittently. As a result, the amount of humidification to the sauna room can be adjusted according to the humidity state of the sauna room, and the sauna room is not over-humidified, and wasteful water discharge can be suppressed.

  Furthermore, the supplied water can be almost completely refined, and it can be dried by the drying operation after the sauna operation is completed, without draining the water that has not been refined slightly remaining in the water reservoir 25, Piping construction for treating the water that could not be refined as wastewater is unnecessary, and as a result, the construction work of the sauna device is simplified.

  That is, even when more water is supplied to the upper surface of the upper rotating plate 20a than the flow rate set by the variation of the constant flow valve 15, water can be stored by the water storage unit 25 and the stored water can be supplied to the rotating plate by the pumping pipe 22. Therefore, the remaining water at the end of the sauna operation can be reduced and the drying operation time can be shortened.

As described above, the liquid micronizer of the present invention is
By controlling the opening and closing of the water supply valve, the amount of retained water in the liquid refinement means can be adjusted. As a result, after the refinement operation is completed, the water supply valve is closed and the remaining water in the water storage section is heated without supplying liquid. It is possible to shorten the drying time when performing the drying operation in which the wind is applied. Furthermore, since there is no remaining water in the liquid micronizer after the drying operation, there is no need for a drain pipe, and there is an effect that the construction work can be easily performed when the liquid micronizer is installed.

  Therefore, for example, utilization to a sauna device, a humidifier, a cooling device, a spraying device, a cleaning device, a plant growing facility, and the like is expected. Moreover, it can be used not only for water but also for other liquid refining equipment such as oil and detergent.
