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 other words, it is necessary to maintain a sufficient amount of water in the tank to cope with the changing humidification amount, and this configuration is not suitable for drying the inside of the apparatus after operation in preparation for bacterial growth or the like. Therefore, the present invention aims to minimize the amount of water stored in the water storage unit and shorten the drying time when drying the apparatus.

  As described above, the present invention can adjust the amount of retained water in the liquid refining means by controlling the opening and closing of the water supply valve. As a result, the water supply valve is closed and liquid is not supplied after the miniaturization operation is completed. It is possible to shorten the drying time when performing a drying operation in which hot air is applied to the remaining water in the water storage unit in the state. Furthermore, since there is no residual water in the liquid micronizer after the drying operation, no drain pipe is required, and the construction work when installing the liquid micronizer can be performed easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(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. Hereinafter, in the present embodiment, the liquid to be refined will be described as water.

  As shown in FIG. 2, the liquid micronizer 3 has a box-shaped main body case 6 having a suction port 4 and an exhaust port 5 on the lower surface, and a wind that connects the suction port 4 and the exhaust port 5 in the main body case 6. A heat exchanger 7 as a heating means provided in the passage, a fan motor 8 as a blowing means, and a liquid refinement means 9 provided between the fan motor 8 and the exhaust port 5 are provided.

  The air passage leading from the fan motor 8 to the liquid micronization means 9 is formed by a fan casing 10, and an auxiliary heat exchanger 11 is provided between the liquid micronization means 9 and the exhaust port 5. 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 is arranged in the vertical direction, and has a liquid refinement means case 12 having an upstream opening and a downstream opening, and a rotation provided inside the liquid refinement means case 12. Means 13 and a water supply pipe 14 as liquid supply means for supplying water to the rotating means 13 are provided.

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

  The rotating means 13 includes a rotary shaft 19 arranged in the vertical direction and a plurality of rotary plates 20a and 20b that rotate about the rotary shaft 19 in the axial direction of the rotary shaft 19 at predetermined intervals in the vertical direction. 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 in the vertical direction.

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

  Further, as shown in FIG. 2, the liquid refinement means case 12 has a water storage part 25 as shown in FIG. 2, so that the amount of water that cannot be pumped by the pumping pipe 22, that is, the water storage amount of the water storage part 25 at the end of the miniaturization operation is reduced. The lower part of the liquid refinement means case 12 has, for example, an inverted trapezoidal shape (convex downward).

  Moreover, the 1st thermistor 26 is provided in the water storage part 25 as a 1st water level detection means.

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

  The control unit 28 includes a control unit 29, a remote controller 30 provided with a display unit and an operation switch (not shown), and a first thermistor 26 as a first water level detection unit.

  The control unit 29 has a microcomputer (hereinafter referred to as a microcomputer, not shown), and the microcomputer drives a pump for supplying hot water to the heat exchanger 7, a fan motor 8, and a rotating shaft 19 by an operation signal from the remote controller 30. The rotating motor 21 and the water supply valve 17 are controlled.

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

  When the sauna is used in the sauna room 1, first, hot water is supplied from a heat source such as a gas water heater or an electric water heater (not shown) to the heat exchanger 7 shown in FIG. 2 through the pipe 31 shown in FIG. Is done. Further, city water is supplied to the water supply pipe 14 through a pipe 32. The city water supplied to the water supply pipe 14 is a very small amount set by the constant flow valve 15, and is stopped by the water supply valve 17 and is not discharged from the water supply pipe 14 until the rotary motor 21 is driven. .

  In this state, when the heat exchanger 7 is operated and the fan motor 8 is driven, the fan motor 8 sucks air in the sauna room 1 through the suction port 4, and the sucked air is absorbed by the heat exchanger 7. Heated. The heated air is sent 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. At this time, the pumping pipe 22 is rotating above the water storage section 25, and when the amount of water stored in the water storage section 25 increases and the water surface approaches the lower end of the water pumping pipe 22, the water storage in the water storage section 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 an inverted conical shape 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.

  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. The water that spreads and becomes a thin film is blown off at high speed from the outer peripheral edge of the rotating plate 20b in the tangential direction.

  Thus, 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 refinement of water.

  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. The water that spreads and becomes a thin film is blown off at high speed from the outer peripheral edge of the rotating plate 20a in the tangential direction.

  Thus, 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 refinement 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.

  Thus, almost all of the water pumped by the pumping pipe 22 is refined and mixed with the heated warm air to form a steam state and discharged from the upper opening, but part of the water is not refined. Slight water droplets adhering to the inner wall of the liquid refinement means case 12 or a minute amount of water droplets dewed on the inner wall after being refined, flow down to the water storage section 25 through the inner wall of the liquid refinement means case 12, and are stored. The

  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 micronization means 9, which is determined by the number of rotating plates 20a, 20b, the number of rotations of the rotary motor 21, etc., 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 section 25 and the amount of water pumped in the pump pipe 22. When supplied for more than min, the amount of refined water increases while increasing the initial buffer amount, and the amount of water supplied from the constant flow valve 15 and the amount of refined water become substantially the same in a steady state.

  That is, during normal sauna operation (S1 in FIG. 5 described later), in a steady state, the amount of water supplied from the constant flow valve 15 and the amount of fine 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 humidification. One feature of the present embodiment is to intermittently control the opening and closing of the water supply valve 17 so that the amount of supplied water does not become excessive.

  Next, the opening / closing control of the water supply valve 17 according to the humidity state of the sauna room 1 will be described.

  First, FIG. 5 shows a flowchart of the control using the first thermistor 26 as the first water level detecting means shown in FIG.

  As shown in FIG. 5, during normal sauna operation, 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.

  When the sauna room 1 becomes highly humid, the amount of humidification decreases and falls below the water supply amount, so the water level rises. When this water level reaches the first thermistor 26 provided in the water storage section 25, the electric resistance of the temperature of the air heated up to the high temperature by the heat exchanger 7 passing through the liquid refinement means case 12 until then is obtained. In contrast to this, since the electrical resistance of the temperature of the water stored in the water reservoir 25 which is lower than the heated air is detected, a large change occurs in the electrical resistance value. The change in the electrical resistance value is detected as a signal to detect an increase in the water level, and the water level is adjusted by closing the water supply valve 17.

  With respect to the installation position of the first thermistor 26, it is necessary to reduce the amount of water stored so that the remaining water in the apparatus can be dried at a predetermined time in the drying operation performed after the sauna operation is completed. It shall be installed at the allowable limit water level.

  In addition, the detection of the water level is determined based on the large change amount of the electric resistance value, but if the second thermistor 27 as the second water level detection means is also provided at the bottom of the water storage unit 25, the bottom In this case, the water is always in contact with the stored water during operation, and further, since the stored water is circulated by the rotating means 13 and has no temperature difference, the second thermistor 27 provided at the bottom and the stored water The detection of the water level can be determined from the electrical resistance difference with the first thermistor 26 provided at the allowable limit water level.

  Further, even if the third thermistor 33 is provided as a third water level detection means at a position where the water level does not reach during normal operation, the first water level provided at the water storage allowable limit level until the water level reaches the water storage allowable limit water level. Both the thermistor 26 and the third thermistor 33 detect the air in the liquid refining means case 12 and detect almost the same electrical resistance value, but the water level reaches the allowable water storage limit water level. Therefore, the detection of the water level can be determined from the difference in electrical resistance between the third thermistor 33 and the first thermistor 26 provided at the water storage allowable limit water level.

  The position of the third thermistor 33 may be arranged at a height where the water level does not reach during normal operation in the water reservoir 25, but is arranged in the air path between the heat exchanger 7 and the liquid refinement means case 12. Even if it does, the effect does not occur.

  However, in a state where the third thermistor 33 is disposed at a position where the water level does not reach during normal operation in the water storage section 25, the first thermistor 26 and the second thermistor 27 are disposed at close positions. As a result, the electric resistance values shown in the drying process are almost equal to each other, so that an effect of facilitating detection and judgment at the time of flooding can be obtained. Further, the third thermistor 33 is made finer with the heat exchanger 7. In the state of being arranged in the air passage between the means cases 12, it is possible to prevent water droplets generated in the liquid refinement means case 12 from being attached, and as a result, it is possible to prevent erroneous detection. Play.

  After it is determined that the water level has reached the first thermistor 26, water is supplied to the heat exchanger 7, and the operation for adjusting the water level in a state where the operation of the fan motor 8 and the rotary motor 21 is continued, After a certain time (for example, 5 to 10 minutes) has elapsed, the water supply valve 17 is opened again.

  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.
