Description

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

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

  That is, a main body case having a suction port and an exhaust port, a heating unit and a blower unit provided in a ventilation path in the main body case, and a miniaturization unit provided between the blower unit and the exhaust port, The means is configured to eject liquid from the water supply pipe (see, for example, Patent Document 1).

JP-A-6-63103

  The problem with the above conventional example is that, in order to discharge the liquid ejected from the nozzle that could not be refined, piping must be constructed in the sauna room, which makes the construction work complicated. That is.

  That is, in the type in which the liquid is ejected from the nozzle and the liquid is refined, the liquid cannot be completely refined, and in the sauna room in order to process a large amount of non-miniaturized liquid remaining in the sauna apparatus. The pipe is extended to discharge this non-fine liquid to the sauna room. It is very troublesome to construct such a pipe in the sauna room aesthetically.

  Therefore, an object of the present invention is to facilitate construction work.

  And in order to achieve this object, the present invention comprises a main body case having a suction port and an exhaust port, a heating unit and a blower unit provided in an air passage connecting the suction port and the exhaust port in the main body case, A liquid refining means provided in the air passage between the blower means and the exhaust port, and the liquid refining means is provided in a cylindrical path opened in a vertical direction and in the cylindrical path. A rotating means, and a liquid supply means for supplying a liquid to the rotating means. The rotating means includes a rotating shaft arranged in the vertical direction and a plurality of shafts fixed at predetermined intervals in the axial direction of the rotating shaft. The liquid supply means has a pipe for transferring the liquid and supplying the liquid to the upper rotary plate, and a constant flow valve arranged in the middle of the pipe, and in the vicinity of the upstream side of the constant flow valve. The liquid supplied to the constant flow valve is heated with a constant flow rate Than to heat the liquid to be supplied to have achieved the above objects.

  As described above, the present invention is configured so that the liquid supplied to the constant flow valve can be heated in the vicinity of the upstream side of the constant flow valve, so that the minimum liquid necessary for miniaturization is provided to the rotating means that rotates at high speed. Since the liquid can be supplied almost quantitatively, as a result, a large amount of drainage is not generated when the liquid is miniaturized.

  That is, the accuracy of the constant flow valve depends on the temperature of the flowing liquid, and the accuracy is particularly bad at low temperatures. Therefore, in the present invention, since the liquid supplied to the constant flow valve can be heated, the constant flow valve can be used within a high accuracy range, so that the minimum liquid necessary for miniaturization is almost quantitatively supplied to the rotating means that rotates at high speed. At the end of miniaturization, almost all of the supplied liquid can be miniaturized or vaporized. As a result, the construction work can be simplified.

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

(Embodiment)
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 includes a main body case 6 having a suction port 4 and an exhaust port 5, and heating provided in an air passage connecting the suction port 4 and the exhaust port 5 in the main body case 6. A heat exchanger 7 as means, a fan motor 8 as air blowing means, and a liquid refinement means 9 provided between the fan motor 8 and the exhaust port 5 are provided.

  An air passage leading from the fan motor 8 to the liquid micronization means 9 is formed by the casing 10, and an auxiliary heat exchanger 11 is provided between the liquid micronization means 9 and the exhaust port 5.

  As shown in FIG. 2, the liquid refinement means 9 includes a cylindrical path 12, a rotating means 13 provided in the cylindrical path 12, and a liquid supply means for supplying water to the rotating means 13. The water supply pipe 14 is provided. The water supply pipe 14 is provided with a constant flow valve 15, and an upstream pipe 16 of the constant flow valve 15 is arranged so as to contact the cylindrical path 12. Further, an on-off valve 17 is provided on the upstream pipe 16 and an on-off valve 18 is provided on the branch pipe of the water supply pipe 14.

  The rotating means 13 is provided with a rotating shaft 19 and a plurality of rotating plates 20 a and 20 b that rotate about the rotating shaft 19 at a predetermined interval in the axial direction of the rotating shaft 19. In the present embodiment, two rotating plates 20a provided above the rotating shaft 19 and two rotating plates 20b provided below are provided.

  A motor 21 for driving the rotating shaft 19 is provided at the upper part of the rotating means 13, and a rotating shaft 19 and a plurality of rotating plates 20 a and 20 b that rotate at high speed by driving the motor 21 are supported at the lower part of the rotating means 13. A holding portion 22 is provided.

  The inner wall of the cylindrical path 12 is provided with a water storage means 24 and a water passage 25 as liquid guide means 23 for guiding water adhering to the inner wall to the lower rotating plate 20b.

  As shown in FIG. 2, the liquid guiding means 23 guides the water adhering to the inner wall of the cylindrical path 12 to the lower rotating plate 20b. The water storage means 24 is provided along the inner wall of the cylindrical path 12 between the rotary plate 20b and the water channel 25 for guiding water from the water storage means 24 to the upper surface of the lower rotary plate 20b. . The water channel 25 has a shape extending from the three sides of the water storage means 24 toward the center of the cylindrical channel 12 and is open toward the center on the upper surface of the lower rotating plate 20b as shown in FIG.

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

  When using a sauna in the sauna room 1, first, hot water is supplied from a heat source such as a gas water heater or an electric water heater (not shown) to the heat exchanger 7 shown in FIG. 2 through the pipe 26 shown in FIG. Is done. Further, city water is supplied to the water supply pipe 14 through a pipe 27. The city water supplied to the water supply pipe 14 is very small and is not discharged from the water supply pipe 14 at this time.

  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 to the cylindrical path 12 by the fan motor 8 through the casing 10.

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

  At this time, the water supply pipe 14 supplies water to the upper surface of the upper rotating plate 20a that rotates at a high speed. The water supplied to the upper surface of the upper rotating plate 20a spreads in the form of a thin film toward the outer peripheral direction due to the centrifugal force caused by the high-speed rotation, and this thin film-shaped water moves from the outer peripheral edge of the rotating plate 20a to the tangential direction. It is blown away at high speed.

  In this way, the water droplets scattered by the centrifugal force collide with the inner wall of the cylindrical path 12 and are crushed, thereby promoting the miniaturization of water.

  And most of the water supplied from the water supply pipe 14 to the upper surface of the upper rotating plate 20a is miniaturized at this time, and is mixed with heated warm air in a steam state.

  On the other hand, among the water droplets scattered by the centrifugal force from the upper rotating plate 20a, a few water droplets that are not miniaturized and adhere to the inner wall of the cylindrical path 12 and a minute amount of water droplets that are condensed on the inner wall after being miniaturized are Then, the water flows through the water storage means 24 through the inner wall of the cylindrical path 12 and is stored. A small amount of water stored in the water storage means 24 is conveyed from the three directions of the water storage means 24 to the upper surface of the lower rotating plate 20b via the water channel 25.

  Thus, even a small amount of water carried to the lower rotating plate 20b is miniaturized by rotating the lower rotating plate 20b at a high speed in the same manner as the upper rotating plate 20a. That is, slight water droplets supplied from the inner wall of the cylindrical path 12 to the upper surface of the lower rotating plate 20b through the water storage means 24 and the water channel 25 are formed in a thin film shape toward the outer periphery by centrifugal force due to high-speed rotation. The water droplets are blown off at high speed from the outer peripheral edge to the tangential direction, and the blown water droplets collide with the inner wall of the cylindrical path 12 to be crushed, thereby promoting the refinement of water.

  As described above, the water supplied to the upper rotating plate 20a is largely refined by the high speed rotation of the upper rotating plate 20a, and a part of the water that has not been refined slightly remains. Water droplets are also transported to the lower rotating plate 20b rotating at high speed via the liquid guiding means 23 provided in the cylindrical path 12, and are almost completely miniaturized.

  Warm air containing water refined by high-speed rotation of the rotary plate 20a and the rotary plate 20b is supplied as steam from the exhaust port 5 to the inside of the sauna chamber 1 by the blowing of the fan motor 8.

  At this time, the amount of water supplied to the upper surface of the upper rotating plate 20a rotating at high speed from the water supply pipe 14 becomes a problem in order for the water droplets carried to the lower rotating plate 20b to be almost completely miniaturized. That is, the amount of water that can be refined is set by the refinement ability of the liquid refinement means 9 determined by the number of rotating plates, the number of revolutions of the motor, and the like.

  When this amount of water is set by the constant flow valve 15, the water temperature becomes a problem. That is, the accuracy of the constant flow valve 15 depends on the water temperature, and the cause is considered to be the temperature dependence of the viscosity coefficient of water.

  FIG. 3 shows the relationship between the temperature of water, the viscosity coefficient of water, and the amount of water. The solid line is the viscosity coefficient of water, the broken line is the amount of water, and the amount of water is the amount of water flowing through the constant flow valve 15 when the constant flow valve 15 is set to 30 cc / min at a water temperature of 40 ° C. As is clear from the graph of FIG. 3, the viscosity coefficient of water changes greatly at low water temperature, and the change decreases as the water temperature increases, and the amount of water flowing through the constant flow valve 15 shows the same tendency. ing.

  Considering such temperature dependence of the constant flow valve 15, the temperature of the water supplied to the constant flow valve 15 should be higher, and as shown in the graph, the water temperature is 40 ° C. When supplying to the upper surface of the rotating plate 20a, the amount of supplied water hardly changes even if the water temperature changes by 1 ° C.

  Thus, since it is necessary to raise the temperature of the water supplied to the constant flow valve 15, as shown in FIG. 2, the upstream pipe 16 of the constant flow valve 15 is connected to the cylindrical path 12 near the exhaust port 5. Arranged to contact the outer surface. In this case, the water supplied to the constant flow valve 15 is heated using hot air passing through the cylindrical path 12 as a heat source.

  That is, the warm air containing micronized water supplied from the exhaust port 5 to the inside of the sauna room 1 is as warm as 50 to 60 ° C., and the outer surface of the cylindrical path 12 near the exhaust port 5 is also warmed. By arranging the upstream pipe 16 of the flow valve 15 so as to be in contact with the outer surface of the cylindrical path 12 near the exhaust port 5, the water supplied to the constant flow valve 15 can be heated. Furthermore, since the warm air temperature is stable and the heated water temperature can be made substantially constant, the accuracy of the constant flow valve 15 can be further improved.

  FIG. 4 shows an example in which the upstream pipe 16 of the constant flow valve 15 is arranged so as to be in contact with the outer surface of the cylindrical path 12 near the exhaust port 5.

  As shown in FIG. 4, the upstream pipe 16 is brought into contact with the outer surface of the cylindrical path 12 in the vicinity of the exhaust port 5 and is reciprocated in a U-shape two times from the bottom to the top. The number of times of reciprocation, that is, the length of the part to be contacted is determined from the maximum value of the required heating amount, and is determined so that it can be heated to the set temperature even when heating from, for example, 5 ° C. in winter when the supply water temperature is minimum.

  Moreover, by providing the auxiliary heat exchanger 11 shown in FIG. 2 between the liquid micronization means 9 and the exhaust port 5, hot air containing micronized water supplied from the exhaust port 5 to the inside of the sauna chamber 1 can be obtained. Since the temperature can be increased, the amount of heat exchange per unit area from the warm air into the upstream pipe 16 through the cylindrical path 12 can be increased, so that the water supplied to the constant flow valve 15 can be supplied for a short time. Can be heated. That is, the length of the contacted portion can be shortened.

  Further, when the sauna operation is interrupted or stopped, the water supply from the water supply pipe 14 is stopped first, and the rotation of the fan motor 8 and the rotating means 13 is stopped with a delay. Therefore, the warm water supplied from the water supply pipe 14 until the water supply is stopped is almost all refined by the high-speed rotation of the upper rotating plate 20a and the lower rotating plate 20b.

  Further, when the water supply is stopped, the on-off valve 17 is closed and then the on-off valve 18 is opened to supply the remaining water in the downstream piping of the on-off valve 17 including the inside of the constant flow valve 15 to the upper rotating plate 20a.

  By discharging the residual water in the pipe, it is possible to prevent the growth of bacteria due to leaving for a long time, and to maintain the quality of the water supplied to the rotating means 13. The remaining water supplied to the rotating means 13 is almost completely refined by the high-speed rotation of the upper rotating plate 20a and the lower rotating plate 20b, and is discharged into the sauna room.

  As described above, since the constant flow valve 15 can be used in a highly accurate range by heating the water supplied to the constant flow valve 15 using hot air as a heat source, the rotating means 13 that rotates at high speed is necessary for miniaturization. The minimum amount of water can be supplied almost quantitatively, and at the end of miniaturization, almost all of the supplied water can be refined or vaporized. As a result, the construction work can be simplified.

  Next, an example in which water supplied to the constant flow valve 15 is heated using hot water as a heat source will be described with reference to the piping configuration of FIG. The same components as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 5, the water-water heat exchanger 31 and the splash nozzle 32 which are not shown in FIG. 2 are provided, and the hot water from the gas water heater or the electric water heater which is the hot water circulation facility 33 is replaced with the heat exchanger 7 and the auxiliary heat. Heat is exchanged between the exchanger 11 and the water-water heat exchanger 31, and the water supplied to the constant flow valve 15 is heated using the hot water after the heat exchange as a heat source. On the other hand, the city water pipe is a branch pipe and is supplied to the constant flow valve 15 and the water-water heat exchanger 31.

  Here, by providing the water-water heat exchanger 31 and the splash nozzle 32, the hot water heated by the water-water heat exchanger 31 can be sprayed from the splash nozzle 32 to the sauna room 1, and water droplets can be generated in the room. This is a liquid refining device that can also perform a splash operation in which water is forcibly sprayed for a humidifying operation that hardly supplies.

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

  The hot water discharged from the hot water circulation facility 33 is distributed on the way to the auxiliary heat exchanger 11, a part of the hot water is supplied to the water-water heat exchanger 31, and the water-water heat exchanger 31 has a splash nozzle. Water supplied to 32 is heated. Moreover, the hot water which heated the air containing micronized water with the auxiliary heat exchanger 11 is sent to the heat exchanger 7, and the air inhaled from the sauna room in the heat exchanger 7 is heated here. The hot water leaving the heat exchanger 7 joins with the hot water heat-exchanged in the water-water heat exchanger 31, returns to the hot water circulation facility 33, is reheated in the hot water circulation facility 33, and is recycled.

  On the other hand, the city water supplied to the constant flow valve 15 is heated by heat exchange with the heat exchanger 7 and the pipe through which the hot water heat-exchanged in the water-water heat exchanger 31 passes. The heat source for this heating is hot water that returns to the hot water circulation facility 33, and does not affect the heat exchange of the heat exchanger 7, the auxiliary heat exchanger 11, and the water-water heat exchanger 31, and in each heat exchanger. Since the heat exchange amount is substantially constant, the water supplied to the constant flow valve 15 can be heated to a substantially constant temperature.

  Furthermore, heat is exchanged with the hot water exiting the heat exchanger 7 and the pipe after the hot water merged in the water-water heat exchanger 31, and the hot water pipe exiting the heat exchanger 7 before the merge Compared to the heat exchange, the amount of hot water is large, and the water supplied to the constant flow valve 15 can be heated with less contact between the pipes.

  As described above, even when hot water is used as a heat source, the constant flow valve 15 can be used in a highly accurate range by heating the water supplied to the constant flow valve 15, so that the rotating means 13 that rotates at high speed is miniaturized. It is possible to supply almost the minimum amount of water necessary for the process, and at the end of miniaturization, almost all of the supplied water can be refined or vaporized. As a result, the construction work can be simplified.

  The rotational speed of the plurality of rotating plates 20a and 20b is set to a rotational speed lower than 3000 rpm (rpm is a unit representing the rotational speed per minute), thereby making it possible to suppress noise caused by high-speed rotation. Play.

  As described above, in the present embodiment, when the liquid refining device 3 is installed in the sauna chamber 1 and used as a sauna device, the water supplied to the constant flow valve 15 is heated in the vicinity of the upstream side of the constant flow valve 15. As a result, the constant flow valve 15 can be used in a highly accurate range, so that the minimum amount of water necessary for miniaturization can be supplied almost quantitatively to the rotating means 13 that rotates at high speed. Therefore, the supplied water can be almost completely refined, and the amount of water that can be naturally dried by the heat remaining in the liquid refinement means 9 without specially discharging the remaining non-refined water. As a result, the construction work of piping for treating the water that could not be refined as wastewater becomes unnecessary, and as a result, the construction work of the sauna device is simplified.

  As described above, the liquid micronizer of the present invention can use a constant flow valve in a highly accurate range by heating water supplied to the constant flow valve, and is necessary for miniaturization of a rotating means that rotates at high speed. Since the minimum amount of water can be supplied almost quantitatively, it becomes possible to refine the water efficiently and almost completely, and it can be dried naturally without draining the water that has not been refined. There is no need to separately provide drainage means.

  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.
