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

(Embodiment 1)
FIG. 1 is an image diagram showing the principle of the water refinement unit of the present invention.

  As shown in FIG. 1, the water refinement unit 1 includes a heating means 2 for heating water, an evaporation tank 3 for evaporating water by the heating means 2, and steam generated in the evaporation tank 3 is steam. A distilled water generation tank 6 that is supplied via the transfer pipe 4 and has a heat exchange means 5 for cooling the steam built therein, a water supply pipe 7 for supplying water to be cooled to the heat exchange means 5, and heat exchange A water conveyance pipe 8 that conveys the water heat-exchanged by the means 5 to the evaporation tank 3, a high-pressure air conveyance pipe 10 that conveys high-pressure air generated in the evaporation tank 3 to the blowing nozzle 9, and a lower part of the distilled water generation tank 6 In addition, a distilled water storage tank 14 with a water level detecting means 13 connected through a connecting pipe 12 provided in the middle of the flow rate adjusting valve 11 and the distilled water stored in the distilled water storage tank 14 by the discharge pressure of the blowing nozzle 9. A suction pipe 1 connected to suck the stored water in the tank 14 And it is made of.

  Also, the steam transfer pipe 4 has an on-off valve 16, the water transfer pipe 8 has an on-off valve 17, the high-pressure air transfer pipe 10 has a discharge pressure adjustment valve 18, and the distilled water generating tank 6 has a water level detection means 19. Is provided.

  In addition, as shown in FIG. 2, the evaporation tank 3 includes an upper case 31 and a lower case 32. The heating means 2 is fixed to the upper case 31, and has a structure that can be detached by, for example, cutting an internal thread in the upper case 31 and an external thread in the lower case 32.

  Thereby, the cleaning and cleaning work in the evaporation tank 3 can be easily performed.

  FIG. 3 shows the positional relationship between the blowing nozzle 9 and the suction pipe 15. The water level in the distilled water storage tank 14 is maintained at a level that does not overflow from the opening of the suction pipe 15 by the water level detection means 13, and the water in the suction pipe 15 is sucked by the high-pressure air blown from the blowout nozzle 9. It has become.

  In the above configuration, the water refining unit performs two kinds of operations of distilled water generation and water refining spray. First, the distilled water generation process will be described.

  In the initial state of operation, the state of each valve is that the flow rate adjustment valve 11 is closed, the on-off valve 16 is open, the on-off valve 17 is open, and the discharge pressure adjustment valve 18 is closed.

  In this state, water is supplied to the evaporating tank 3 through the water supply pipe 7 and the water transport pipe 8, and the energization of the heating means 2 (for example, an electric heater) is started to heat the water stored in the evaporating tank 3. Evaporate.

  The evaporated vapor passes through the vapor transfer pipe 4 and is sent to the distilled water production tank 6 and is cooled by the heat exchange means 5 provided at the upper part of the distilled water production tank 6 to become condensed water, that is, distilled water. It is stored in the generation tank 6.

  For example, when the sauna is used, the amount of distilled water generated is set according to the available sauna time, and the water level detection means 19 provided in the distilled water generating tank 6 detects the set water level according to the available sauna time. As a result, the energization of the heating means 2 is stopped and the flow rate adjusting valve 11 is opened to allow a set amount of distilled water to flow into the distilled water storage tank 14. This set amount is set by the water level detection means 13 in the distilled water storage tank 14.

  Further, when an electric heater is used as the heating means 2 as described above, this distilled water generation process is preferably performed at night when midnight power can be used, thereby reducing the running cost, that is, the electricity cost.

  Next, the water atomization spray process will be described.

  In the initial stage of operation, the state of each valve is that the flow rate adjustment valve 11 is closed, the on-off valve 16 is closed, the on-off valve 17 is open, and the discharge pressure adjustment valve 18 is closed.

  In this state, first, a fixed amount of water is supplied to the evaporation tank 3 from a water supply (not shown) via the water supply pipe 7 and the water transport pipe 8 shown in FIG. This water is supplied by the on-off valve 17, and a certain amount can be supplied by measuring the open time.

  After supplying a certain amount of water to the evaporation tank 3, the on-off valve 17 is closed and energization to the heating means 2 is started. At that time, the on-off valve 16 of the vapor transfer pipe 4 is closed, the discharge pressure adjusting valve 18 of the high-pressure air transfer pipe 10 is closed until it rises to the set pressure, and the evaporation tank 3 is sealed.

  In this sealed state, the water in the evaporation tank 3 is heated by the heating means 2 and evaporates, whereby the pressure in the evaporation tank 3 rises.

  When the increased pressure rises to the set pressure of the discharge pressure adjusting valve 18, the discharge pressure adjusting valve 18 is opened, and the high pressure air is conveyed to the blowing nozzle 9 through the high pressure air conveying pipe 10. High pressure air begins to blow out from the tip of the.

  At this time, as shown in FIG. 3, the blowing nozzle 9 and the open end of the suction pipe 15 are close to each other, and distilled water in the suction pipe 15 is sucked by the high-pressure air blown from the blowing nozzle 9 and refined. It is sprayed as a gas-liquid mixed fluid.

  Then, when distilled water in the suction pipe 15 is sucked and the water level in the distilled water storage tank 14 starts to drop, the water level detection means 13 detects it, the flow control valve 11 opens a little, and the water level in the distilled water storage tank 14 is changed. By maintaining, the amount of distilled water in the suction pipe 15 sucked by the high-pressure air blown from the blowout nozzle 9 can be made constant.

  If the amount of water supplied to the evaporating tank 3 is large and the heating capacity of the heating means 2 is not sufficient, the supplied water can be hot water from a gas water heater or an electric water heater, By providing this, the pressure in the evaporation tank 3 can be increased in a short time, and the rise time can be shortened.

  In this way, by using distilled water as the supply water to the two-fluid nozzle, the scale does not adhere to the nozzle, and maintenance work such as cleaning and cleaning can be saved. Furthermore, the evaporation tank 3 can be used by switching the distilled water generating function and the high-pressure air generating function, and a small water refinement unit can be provided.

(Embodiment 2)
FIG. 4 shows the case where there are two evaporating tanks 3 in FIG. 1, and both evaporating tanks 3a and 3b can be used to produce more distilled water and more refined water. Can be sprayed.

  Further, by generating distilled water in the evaporating tank 3a and generating high-pressure air in the evaporating tank 3b, it is possible to generate distilled water while performing the water atomization spray.

  Therefore, it is possible to continuously refine and spray distilled water of a certain amount or more stored in the distilled water generation tank 6. That is, compared with the case where the number of the evaporation tanks 3 is one, water atomization spray can be performed continuously for a long time.

  The details will be described with respect to a sauna apparatus using a water refining unit that can make full use of this effect.

  In FIG. 5, reference numeral 21 denotes a sauna room. A door 23 is provided on the front wall 22 of the sauna room 21 so as to be opened and closed, and a bathtub 24 is provided inside. A water refinement device 27 is attached to the opening 26 of the ceiling surface 25 of the sauna room 21.

  As shown in FIGS. 6 and 7, the water refiner 27 incorporates the water refiner unit 1 described in FIG. 1 in a main body case 30 having an air supply port 28 and an exhaust port 29. 28, the heating means 41 provided inside the main body case 30, the blowing means 43 for sending the air that has passed through the heating means 41 to the blowing path 42, and the direction of the wind that passes through the blowing path 42 and is discharged from the exhaust port 29. It is comprised by the wind direction change board 33 to change.

  In the water miniaturization unit 1, the difference from the first embodiment is that the evaporation tank 3 is an evaporation tank 3a, an evaporation tank 3b, a steam transfer pipe 4 is a steam transfer pipe 4a, a steam transfer pipe 4b, and a water transfer pipe 8 is water transfer. The pipe 8a, the water conveyance pipe 8b, and the high-pressure air conveyance pipe 10 are the high-pressure air conveyance pipe 10a and the high-pressure air conveyance pipe 10b, and the number of components is increased from one to two.

  In the above configuration, a distilled water generation process performed when the sauna is not used will be described.

  In the initial stage of operation, the flow rate adjustment valve 11 is closed, the on-off valves 16a and 16b are open, the on-off valves 17a and 17b are open, and the discharge pressure adjustment valve 18 is closed.

  In this state, water is supplied to the evaporation tanks 3a and 3b via the water supply pipe 7 and the water transport pipes 8a and 8b, and the heating means 2a and 2b are energized, and the water stored in the evaporation tanks 3a and 3b. Is heated and evaporated.

  The evaporated steam passes through the steam transport pipes 4a and 4b, is sent to the distilled water generation tank 6, is cooled by the heat exchange means 5 provided in the upper part of the distilled water generation tank 6, and becomes condensed water, that is, distilled water. It is stored in the distilled water production tank 6.

  The amount of distilled water generated is set according to, for example, the sauna usable time (about 3 liters in one hour), and the water level detecting means 19 (FIG. 4) provided in the distilled water generating tank 6 can use the sauna. By detecting the set water level according to time, the energization of the heating means 2a and 2b is stopped, and the flow rate adjusting valve 11 is opened to allow a set amount of distilled water to flow into the distilled water storage tank. This set amount is set by the water level detection means 13 (FIG. 4) in the distilled water storage tank 14.

  In this distilled water generation process, distilled water can be generated in a shorter time than in the case of the first embodiment where there is only one evaporation tank 3.

  Next, the water atomization spraying process when the sauna is used, that is, the sauna chamber 21 is filled with water atomized air will be described.

  Before that, it is necessary to heat the inside of the sauna room 21 first, and while supplying hot water to the heating means 41 shown in FIG. 7 provided inside the main body case 30 of the air supply port 28 shown in FIG. The air blowing means 43 that sends the air that has passed through 41 to the air blowing path 42 is operated.

  The air in the sauna chamber 21 sucked into the main body case 30 from the air supply port 28 passes through the heating means 41, is heated, passes through the air passage 42, and is discharged from the exhaust port 29 into the sauna chamber 21. .

  By repeating this, the temperature of the air in the sauna chamber 21 is raised. When a normal sauna is used, the temperature is about 40 ° C. When this temperature is reached, the water atomization spray process starts.

  In the initial stage of operation, the flow rate adjustment valve 11 is closed, the on-off valves 16a and 16b are closed, the on-off valves 17a and 17b are opened, and the discharge pressure adjustment valve 18 is closed.

  In this state, first, a fixed amount of water is supplied to the evaporation tanks 3a and 3b from a water supply (not shown) through the water supply pipe 7 and the water transport pipes 8a and 8b shown in FIG. This water is supplied by the on-off valves 17a and 17b, and a certain amount can be supplied by measuring the open time.

  After supplying a certain amount of water to the evaporation tanks 3a and 3b, the on-off valves 17a and 17b are closed, and energization to the heating means 2a and 2b is started. At that time, the open / close valves 16a and 16b of the vapor transfer pipes 4a and 4b are closed, the discharge pressure adjusting valve 18 of the high-pressure air transfer pipes 10a and 10b is closed until the set pressure is raised, and the evaporation tanks 3a and 3b are sealed. It becomes.

  In this sealed state, the water in the evaporation tanks 3a and 3b is heated by the heating means 2a and 2b and evaporates, whereby the pressure in the evaporation tanks 3a and 3b increases.

  When the increased pressure rises to the set pressure of the discharge pressure adjusting valve 18, the discharge pressure adjusting valve 18 is opened, and the high pressure air is conveyed to the blowing nozzle 9 through the high pressure air conveying pipes 10a and 10b. High pressure air begins to blow out from the tip of the nozzle 9.

  At this time, as shown in FIG. 3, the blowing nozzle 9 and the open end of the suction pipe 15 are close to each other, and distilled water in the suction pipe 15 is sucked by the high-pressure air blown from the blowing nozzle 9 and refined. It is sprayed as a gas-liquid mixed fluid.

  As shown in FIGS. 6 and 7, the blowout nozzle 9 is provided outside the air passage 42, and the gas-liquid mixed two fluids (miniaturized water) sprayed from the exhaust port 29 are supplied to the wind direction by the wind direction changing plate 33. It is supplied to the sauna room 21 on the wind blown from the air passage 42 through the exhaust port 29.

  Then, when distilled water in the suction pipe 15 is sucked and the water level in the distilled water storage tank 14 starts to drop, the water level detection means 13 detects it, the flow control valve 11 opens a little, and the water level in the distilled water storage tank 14 is changed. By maintaining, the amount of distilled water in the suction pipe 15 sucked by the high-pressure air blown from the blowout nozzle 9 can be made constant.

  At this time, if the water level detecting means 19 (FIG. 4) provided in the distilled water generating tank 6 detects that the water level has dropped, the evaporating tank 3a shifts to the distilled water generating process.

  That is, an on-off valve (not shown) is provided in the high-pressure air conveying pipe 10a, and by closing the on-off valve, it becomes possible to generate high-pressure air only in the evaporation tank 3b, Distilled water can also be generated.

  In this way, by using distilled water as the supply water to the two-fluid nozzle, the scale does not adhere to the nozzle, and maintenance work such as cleaning and cleaning can be saved.

  Further, by generating distilled water in the evaporating tank 3a and generating high-pressure air in the evaporating tank 3b, it is possible to generate distilled water while performing the water atomization spray.

  Therefore, it is possible to continuously refine and spray distilled water of a certain amount or more stored in the distilled water generation tank 6. That is, compared with the case where the number of the evaporation tanks 3 is one, water atomization spray can be performed continuously for a long time.

  Furthermore, in the sauna apparatus, the vaporization of water is promoted by using a two-fluid nozzle, drainage is not required without wasting supply water, and as a result, energy loss can be suppressed, and drainage means can be used. There is an effect that it is not necessary to provide it separately.

  As described above, the present invention has a built-in heating means for heating water, an evaporation tank for evaporating water by the heating means, and steam generated in the evaporation tank is supplied via the steam transport pipe and the steam. A distilled water generation tank having a built-in heat exchange means for cooling the water, a water supply pipe for supplying water to be cooled to the heat exchange means, and water exchanged by the heat exchange means to the evaporation tank, A water conveyance pipe provided with an on-off valve in the middle, and high-pressure air generated in the evaporation tank are conveyed to a blowout nozzle provided on the exhaust port side in the air passage, and a discharge pressure from the blowout nozzle in the middle A high-pressure air conveyance pipe provided with a pressure adjustment valve for adjusting the flow rate, and a distilled water storage tank with a water level detection means connected to a lower part of the distilled water generation tank through a connecting pipe provided in the middle of the flow rate adjustment valve; The discharge pressure of the blowing nozzle in this distilled water storage tank Ri wherein a water miniaturization unit having a suction tube connected to suck the water stored distilled water storage tank, it is possible to suppress the clogging of the discharge port of the nozzle blow.

  That is, in the present invention, by using distilled water as the supply water to the two-fluid nozzle, scales do not adhere to the nozzle, and maintenance work such as cleaning and cleaning can be saved.

  Further, by using a two-fluid nozzle, the vaporization of water is promoted, drainage is not required without wasting supply water, and as a result, energy loss can be suppressed and there is no need to separately provide drainage means. It will be a thing.

  That is, in the present invention, since water can be easily refined using a two-fluid nozzle, it is expected to be used for, for example, a sauna device or other plant growing equipment.
