JP-A-4-11068

  The problem with the above conventional example is that water remains in the liquid supply pipe when the miniaturization is stopped, and the remaining water touches the air during the stop time, so that there is a possibility that bacteria may be generated in the remaining water in the liquid supply pipe. That is.

  That is, if the stop time is long, many bacteria may be generated in the remaining water in the liquid supply pipe. During the next operation, micronized water containing bacteria will be supplied by the blower means. There is a demand for supplying clean water to the miniaturization means.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to supply clean water free of bacteria to a liquid refinement means.

The liquid supply means includes a water supply pipe that transports the liquid and supplies the liquid to the upper rotary plate, a constant flow valve arranged in the middle of the water supply pipe, and a downstream side of the constant flow valve And the water supply pipe on the downstream side of the first on-off valve. In the middle of this branched pipe, a second on-off valve is provided above the branch point, and the tip of the branched pipe is opened upward above the second on-off valve. The above object is achieved by eliminating the residual water in the piping to be supplied.

  As described above, according to the present invention, the first on-off valve is provided on the downstream side of the constant flow valve, the water supply pipe on the downstream side of the first on-off valve is branched, and a branch point is located in the middle of the branched pipe. A second opening / closing valve is provided further upward, and the tip of the pipe branched above the second opening / closing valve is opened upward, so that at the end of liquid miniaturization, the first opening / closing valve is closed and the liquid is discharged. By opening the second on-off valve for opening the supply pipe to the atmosphere, residual water in the pipe supplying the liquid can be eliminated.

  That is, if there is residual water in the water supply pipe that supplies liquid to the upper rotating plate, the tip of the water supply pipe is open, so that the residual water in the water supply pipe touches the air and bacteria are generated. Therefore, in the present invention, the residual water on the downstream side of the first on-off valve can be eliminated, that is, the first on-off valve can be closed and the second on-off valve can be opened to eliminate the residual water in contact with the air. At the start of the next liquid micronization, there is an effect that clean water without generation of bacteria can be supplied to the micronization means.

As a result, in order to discharge the liquid that cannot be refined, the ceiling of the sauna room is discharged. When the liquid refining device is installed on the surface, there is no need to construct piping in the sauna room, and the construction work can be simplified.

  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 the water supply pipe 14 on the downstream side of the constant flow valve 15 is arranged so as to be in contact with the cylindrical path 12. Further, the first on-off valve 17 is provided on the downstream pipe of the constant flow valve 15, and the second on-off valve 18 is provided on the branch pipe 16 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 via 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.

  Thereafter, when the 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 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-like water is moved tangentially from the outer peripheral edge of the rotating plate 20a. 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 or a minute amount of water droplets that are condensed on the inner wall after being miniaturized 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. Then, 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.

  Now that the basic configuration and operational effects of the present embodiment have been understood, the features of the present embodiment will be described below.

  FIG. 3 shows the installation positions of the first on-off valve 17 and the second on-off valve 18.

  As shown in FIG. 3, the first on-off valve 17 branches downstream of the constant flow valve 15, and the second on-off valve 18 branches off the pipe downstream of the first on-off valve 17. The tip of the branch pipe 16 is opened upward. FIG. 3 shows the case where the branched pipe is L-shaped, but the branched pipe may have other shapes, and the first on-off valve 17 can be opened by opening the second on-off valve 18. The residual water in the lower pipe may fall naturally from the water supply pipe 14 onto the upper surface of the upper rotating plate 20a.

  FIG. 4 shows the open / close state of the first open / close valve 17 and the second open / close valve 18. 4A shows a sauna (liquid refinement) operation, and FIGS. 4B to 4D show a sauna (liquid refinement) operation stop.

  FIG. 4A shows a sauna operation, the first on-off valve 17 is open, the second on-off valve 18 is closed, and the constant flow valve 15 is attached to the upper surface of the upper rotating plate 20a from the water supply pipe 14 by the constant flow valve 15. A constant amount of water is supplied, the motor 21 for driving the fan motor 8 and the rotating shaft 19 shown in FIG. 2 is in an operating state, the rotating plates 20a and 20b are rotated, and as shown in FIG. In the cylindrical path | route 12, it is blowing in the direction of a broken-line arrow.

  FIG. 4B shows the upper surface of the rotating plate 20a above the water supply pipe 14 by closing the first on-off valve 17 immediately after the sauna operation is stopped (a stop button on an operation panel such as a remote controller not shown) is pressed. The supply of water stops, and there is residual water in the water supply pipe 14 below the first on-off valve 17 and in the branch pipe 16 below the second on-off valve 18. The operation states of the fan motor 8 and the motor 21 are the same as those in FIG.

  4 (c) shows a state in which there is residual water in the pipe of FIG. 4 (b), and the second on-off valve 18 is opened to open the pipe to the atmosphere, so that the inside of the water supply pipe 14 and the branch pipe 16 The remaining water is naturally dropped, and water is supplied from the water supply pipe 14 to the upper surface of the upper rotating plate 20a. The operation state of the fan motor 8 and the motor 21 is the same as in FIG. 4A, and the residual water supplied to the upper surface of the upper rotating plate 20a is refined and supplied as steam from the exhaust port 5 to the inside of the sauna room 1. Is done.

  FIG. 4D shows a state in which all the remaining water in the pipe naturally falls and water is not supplied from the water supply pipe 14 to the upper surface of the upper rotating plate 20a. Immediately after this state is reached, the upper rotating plate 20a, Since water remains on the upper surface of the lower rotating plate 20b, the fan motor 8 and the motor 21 have been operating for a while even in this state. Usually, after opening the second on-off valve 18 in FIG. 4 (c), it is about one minute until all the remaining water is refined and supplied as steam from the exhaust port 5 to the inside of the sauna room 1, The fan motor 8 and the motor 21 may be left and operated for a time.

  As described above, the first on-off valve 17 is provided on the downstream side of the constant flow valve 15, the water supply pipe 14 on the downstream side of the first on-off valve 17 is branched, and the branch pipe 16 that is branched is halfway. A second on-off valve 18 is provided above the branch point, and the tip of the branch pipe 16 is opened upward above the second on-off valve 18 so that the inside of the pipe for supplying the liquid at the end of liquid miniaturization is provided. By opening the second on-off valve 18 for opening to the atmosphere, residual water in the pipe for supplying the liquid can be eliminated.

  That is, if there is residual water in the water supply pipe 14 that supplies the liquid to the upper rotating plate 20a, the tip of the water supply pipe 14 is open. Occur. Therefore, in this embodiment, the residual water downstream of the first on-off valve 17 is eliminated, that is, the first on-off valve 17 is closed and the second on-off valve 18 is opened to eliminate the residual water that comes into contact with air. Therefore, at the start of the next liquid micronization, there is an effect that clean water without generation of bacteria can be supplied to the liquid micronizer 9.

  Furthermore, since the remaining water is supplied to the rotating means 13 that rotates at high speed, the remaining water can be almost all refined or vaporized. As a result, the sauna room 1 is used to discharge the liquid that could not be refined. There is no need to install pipes on the pipe, and the construction work can be simplified.

  Next, when the first on-off valve 17 is closed and this upstream residual water is supplied to the liquid micronization means 9 at the start of liquid micronization, clean water free of germs is supplied more safely. Therefore, the case where the water supplied on the downstream side of the constant flow valve 15 is heated will be described. That is, the first on-off valve 17 is closed so that the residual water on the upstream side does not come into contact with air. However, it is difficult to completely shut off, and there is a possibility that germs may be generated when stopped for a long time.

  The bacteria in question here are Legionella bacteria, which tend to occur at a water temperature of around 20-40 ° C. and are said to die at 50 ° C. or higher (almost instantaneously at 70 ° C.).

  Therefore, in this embodiment, as shown in FIG. 2, the water supply pipe 14 on the downstream side of the constant flow valve 15 is arranged so as to contact the outer surface of the cylindrical path 12 in the vicinity of the exhaust port 5 (in the figure). Dotted line part A). In this case, the water supplied to the upper rotating plate 20a is heated using warm air passing through the cylindrical path 12 as a heat source.

  That is, the warm air containing the micronized water supplied from the exhaust port 5 to the inside of the sauna room 1 is warm at 60 to 70 ° C., and the outer surface of the cylindrical path 12 is also warmed. By arranging the water supply pipe 14 on the side 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 upper rotating plate 20a can be heated to a temperature at which Legionella bacteria are killed. .

  Furthermore, since the warm air temperature is stable and the heated water temperature can be made substantially constant, the heating time is also constant, and the water supply pipe 14 on the downstream side of the constant flow valve 15 is a multi-stage U-shape indicated by a dotted line portion A in FIG. By setting it as a structure, even if Legionella bacteria generate | occur | produce in the residual water in piping and the death conditions of Legionella bacteria are 50 degreeC for 1 minute, the generated Legionella bacteria can be killed.

  A multi-stage U-shaped configuration will be described in detail.

  As shown in FIG. 2, the water supply pipe 14 on the downstream side of the constant flow valve 15 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 horizontal U-shape from top to bottom. ing. 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 water supply pipe 14 on the downstream side of the constant flow valve 15 through the cylindrical path 12 can be increased. The water supplied from can be heated in a short time. That is, the length of the contacted portion can be shortened.

  As described above, by eliminating the residual water that comes into contact with the air in the piping, the generation of bacteria can be prevented, and clean water free from the generation of bacteria can be supplied to the micronization means. By heating the water supply pipe 14 on the downstream side, that is, heating the water supplied to the upper rotating plate 20a, it is possible to supply clean water free of germs to the upper rotating plate 20a more safely. Play.

(Embodiment 2)
Next, an example of heating water supplied to the upper rotating plate 20a on the downstream side of the constant flow valve 15 will be described with reference to the piping configuration of FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 5, the water-water heat exchanger 31 as a water heating means and the splash which sprays the hot water after heat-exchange with this water-water heat exchanger 31 to the sauna room 1 which was not illustrated in FIG. A part of hot water from a gas water heater or an electric water heater which is provided with a nozzle 32 and is a hot water circulation facility 33 is exchanged in the water-water heat exchanger 31 (the heat exchanger 7 and the auxiliary heat exchanger 11). The water supply pipe 14 on the downstream side of the constant flow valve 15 is configured to contact the water-water heat exchanger 31 to heat the water supplied to the upper rotating plate 20a on the downstream side of the constant flow valve 15. doing. On the other hand, the city water pipe branches off, and the city water is supplied to the constant flow valve 15 and the water-water heat exchanger 31.

  Further, the third on-off valve 34 is provided in the pipe 35 connecting the splash nozzle 32 and the water-water heat exchanger 31, and the pipe 35 on the downstream side of the third on-off valve 34 is branched, and this branched pipe is provided. In the middle of this, a fourth on-off valve 36 is provided above the branch point, and the tip of the branched pipe is opened upward above the fourth on-off valve 36.

  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. It is a sauna device that can perform splash operation that forcibly sprays water for humidification operation that hardly supplies.

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

  As shown in FIG. 5, the third on-off valve 34 is connected to the pipe 35 connecting the splash nozzle 32 and the water-water heat exchanger 31, and the fourth on-off valve 36 is on the downstream side of the third on-off valve 34. The pipe 35 is branched and installed above the branching point in the middle of the branched pipe, and the tip of the branched pipe is opened upward. FIG. 5 shows the case where the branched pipe is L-shaped, but the branched pipe may have another shape, and the third on-off valve 34 is closed and the fourth on-off valve 36 is opened. Thus, the remaining water below the third on-off valve 34 may drop naturally from the splash nozzle 32.

  Further, when the splash nozzle 32 has a built-in valve that blocks the opening at the tip, that is, seals the inside of the pipe 35 so that it does not come into contact with air when spraying is stopped, the fourth on-off valve 36 may not be provided.

  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 water supplied to the upper rotating plate 20 a on the downstream side of the constant flow valve 15 is heated by configuring the water supply pipe 14 on the downstream side of the constant flow valve 15 to contact the water-water heat exchanger 31. ing. The heat source for this heating is the main body of the water-water heat exchanger 31, and it can be heated to a higher temperature if it is in contact with the vicinity of the inlet of the hot water discharged from the hot water circulation facility 33.

  Further, as shown in FIG. 6A, the water supply pipe 14 on the downstream side of the constant flow valve 15 is also in contact with the outer surface of the cylindrical path 12, that is, the cylindrical path 12 and the water-water heat exchanger. It is preferable to configure so as to be sandwiched by 31. With this configuration, the heat of hot air passing through the cylindrical path 12 can also be used, and the water supply pipe 14 on the downstream side of the constant flow valve 15 can be heated rather than contacting only the water-water heat exchanger 31. . FIG. 6B shows the U-shaped pipe described in the first embodiment. By closing the first on-off valve 17 and opening the second on-off valve 18, a U-shape is formed in the horizontal direction from top to bottom so that water in the pipe naturally falls.

  As described above, even when the water-water heat exchanger 31 is provided, the remaining water below the third on-off valve 34 can be drained from the splash nozzle 32 when the sauna operation is stopped. At the start, there is an effect that clean water without generation of bacteria can be sprayed from the splash nozzle 32 to the sauna room 1.

  Furthermore, by heating the water supplied from the water supply pipe 14 on the downstream side of the constant flow valve 15 to the upper rotating plate 20a, clean water free of germs can be supplied to the upper rotating plate 20a more safely. There is an effect.

  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 first and second embodiments, when the liquid refining device 3 is installed in the sauna chamber 1 and used as a sauna device, residual water on the downstream side of the first on-off valve 17 is eliminated. By closing the first on-off valve 17 and opening the second on-off valve 18, residual water that comes into contact with air can be eliminated. Therefore, at the start of the next liquid refinement, clean water that does not generate bacteria is liquid. There is an effect that it can be supplied to the miniaturization means 9.

  Further, in the sauna apparatus having the water-water heat exchanger 31 as the water heating means and capable of performing the splash operation, the third on-off valve 34 is closed and the fourth on-off valve 36 is opened to open the third on-off. Residual water below the valve 34 can be drained from the splash nozzle 32, and at the start of the next splash operation, clean water free from germs can be sprayed from the splash nozzle 32 to the sauna chamber 1. .

  In addition, since the residual water is supplied to a rotating means that rotates at high speed, the residual water can also be almost completely refined or vaporized. As a result, in order to discharge the liquid that could not be refined, a pipe is connected to the sauna room. There is also no need to construct a construction work, and the construction work can be simplified.

  As described above, the liquid refinement apparatus of the present invention eliminates residual water on the downstream side of the first on-off valve, that is, closes the first on-off valve and opens the second on-off valve, thereby touching the air. Since the residual water can be eliminated, clean water without generation of bacteria can be supplied to the micronization means at the start of the next liquid micronization, and the water can be efficiently and almost completely micronized. Since the water that has not been refined can be naturally dried without being drained, it is not necessary to separately provide a draining 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.
