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

  For example, a liquid refinement unit used in a sauna apparatus has the following configuration.

That is, a main body case having an air supply port and an exhaust port, a blower means provided in an air passage in the main body case, and a liquid refinement means provided between the blower means and the exhaust port, the liquid refinement The means is configured to supply the liquid to the upper surface of the rotating disk, and to disperse the liquid thinly spread on the disk outward by centrifugal force to make it finer (for example, see Patent Document 1).
JP-A-4-11068

  Since the conventional example is used in a factory or the like, the main body case itself is large and no consideration is given to downsizing, and thus it cannot be applied to, for example, a sauna apparatus as it is.

  That is, in the sauna apparatus, since the liquid miniaturization unit is disposed on the ceiling portion, the downsizing of the unit is strongly demanded. Thus, it becomes impossible to arrange the air supply port and the exhaust port provided on the upper surface side of the main body case, and as a result, it was difficult to apply this conventional example to the sauna device.

  Accordingly, the present invention aims to reduce the size.

  In order to achieve this object, the present invention is arranged in a vertical direction, and a cylindrical body in which an upper end opening serves as an air outlet and a lower end opening serves as an air inlet, and the cylindrical body is directed in the vertical direction. A rotating shaft arranged; a plurality of rotating plates fixed at predetermined intervals in the axial direction of the rotating shaft; a liquid supply unit for supplying liquid to the upper surface of the upper rotating plate among the plurality of rotating plates; A liquid resupply unit for guiding the liquid in the cylinder to the upper surface of the lower rotating plate, and among the rotating plates, the lowermost rotating plate has a smaller diameter than the upper rotating plate, This achieves the intended purpose.

  As described above, the present invention is arranged in a vertical direction, a cylinder having an upper end opening serving as an air outlet and a lower end opening serving as an air inlet, and a rotary shaft disposed in the cylinder in the vertical direction. A plurality of rotating plates fixed at predetermined intervals in the axial direction of the rotating shaft, a liquid supply unit for supplying liquid to the upper surface of the upper rotating plate among the plurality of rotating plates, and the liquid in the cylinder A liquid refeeding section that guides the upper surface of the lower rotating plate, and among the plurality of rotating plates, the lowermost rotating plate has a smaller diameter than the upper rotating plate, Miniaturization can be achieved.

  That is, a rotating shaft is arranged in the vertical direction in a cylindrical body in which the upper end opening is an air outlet and the lower end opening is an air inlet, and a plurality of rotating plates are arranged at predetermined intervals in the axial direction of the rotating shaft. Since the air outlet is fixedly arranged at the upper end opening of the cylinder and the air inlet is distributed at the lower end opening, the size of the cylinder itself can be reduced, and as a result, downsizing is achieved. Will be able to.

  Also, if the cylinder is small, that is, if its diameter is reduced, providing a plurality of rotating plates inside increases the airflow resistance, and as a result, increases the capacity of the blower connected to the air inlet of the cylinder. In the present invention, the lowermost rotary plate of the plurality of rotary plates has a smaller diameter than the upper rotary plate in the present invention. ing.

  If this point is further explained, in the present invention, since the liquid is supplied from the liquid supply unit to the upper surface of the upper rotating plate, the upper rotating plate is used to increase the centrifugal force. However, it is not preferable to reduce the diameter of the lowermost rotating plate, but the lowermost rotating plate only needs to be refined by the centrifugal force of a very small amount of liquid that could not be refined by the upper rotating plate. It can be made smaller.

  And even if the diameter of the lowermost rotary plate is reduced in this way, it becomes possible to significantly reduce the ventilation resistance in the cylinder, which prevents the above-described expansion of the capacity of the blower, resulting in a smaller size. It will be possible to achieve.

  Even if the diameter of the lowermost rotating plate is reduced in this way, as described above, the amount of liquid supplied here is very small in the first place, so the amount of liquid scattered from the outer peripheral surface is also small. With such a small amount of scattering, the time it takes for the air to blow from the blower between the outer peripheral surface of the rotating plate and the inner peripheral surface of the cylindrical body before the scattered liquid collides with the inner surface of the cylindrical body. By increasing the length, miniaturization can be sufficiently performed.

  That is, even if the size is reduced, the size reduction can be achieved without reducing the efficiency of liquid miniaturization.

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

  As shown in FIG. 1, the liquid refinement unit of the present embodiment is arranged in a vertical direction, and a cylindrical body 3 in which an upper end opening is an air outlet 1 and a lower end opening is an air inlet 2, and this cylinder A rotating shaft 4 arranged in the vertical direction in the body 3, a plurality of rotating plates 5, 6, 7, and 8 fixed at predetermined intervals in the axial direction of the rotating shaft 4, and the plurality of rotating plates 5 to 8 Among them, a liquid supply unit 9 for supplying water (in some cases, warm water) as an example of a liquid to the upper surface of the upper rotating plate 5, and the liquid in the cylindrical body 3 are supplied to the lower rotating plates 6, 7, 8. Liquid refeeding portions 10, 11, and 12 that are guided to the upper surface.

  A motor 13 is connected to the upper end of the rotating shaft 4, and the lower portion of the rotating shaft 4 is fixed by a bearing 4a.

  In addition, a blower (not shown) is connected to the air inlet 2 of the cylindrical body 3 via a blower passage 14, and further to the air outlet 1 of the cylindrical body 3 via a blower passage 15, a steam outlet ( A steam discharge port (not shown) of a sauna room (not shown) is connected to the steam outlet.

  That is, the liquid micronization unit shown in FIG. 1 is arranged on the ceiling surface of a sauna room (not shown) so that steam can be supplied to the sauna room.

  When the sauna is used in the sauna room, the motor 13 and the blower are first driven.

  By driving the motor 13, the plurality of rotating plates 5, 6, 7, and 8 are rotated together with the rotating shaft 4.

  Also, the hot air heated by the blower is supplied through a hot water heat exchanger (not shown) into the cylinder 3 through the air passage 14 and the air outlet 1, and then this cylinder It is discharged from the body 3 into a steam outlet (not shown) of a sauna room (not shown) via the air outlet 1, the air passage 15, and the steam outlet (not shown).

  When the above state is stabilized, water is supplied from the liquid supply unit 9 to the upper surface of the uppermost rotary plate 5.

  Thus, the water supplied to the upper surface of the uppermost rotating plate 5 receives the centrifugal force of the rotating plate 5 and spreads uniformly to the outer peripheral side, and eventually scatters from the outer peripheral surface to the inner surface of the cylindrical body 3. And atomized.

  The atomized liquid then collides with the inner surface of the cylinder 3 and further atomization is promoted. The atomized liquid is heated by the warm air rising through the gap between the rotating plate 5 and the inner surface of the cylinder 3. It is conveyed and discharged to a steam discharge port (not shown) of a sauna room (not shown) through the air outlet 1, the air passage 15, and the steam outlet (not shown) described above.

  Of the atomized liquid that has collided with the inner surface of the cylindrical body 3 from the rotating plate 5, the liquid reliquefied on the inner surface of the cylindrical body 3 is supplied to the upper surface of the lower rotating plate 6 by the liquid resupply unit 10. It has become.

  That is, the liquid resupply units 10 to 12 are configured to resupply the water collected by the jars 10a to 12a to the upper surfaces of the lower rotary plates 6, 7, and 8 through the jars 10b to 12b. .

  As described above, in the present embodiment, the water supplied from the liquid supply unit 9 to the upper surface of the uppermost rotary plate 5 is scattered and atomized using the four rotary plates 5, 6, 7, and 8. In addition, there is no residual water dripping downward under the lowermost rotating plate 8, and therefore no configuration for residual water treatment is required, and this also makes it possible to reduce the ventilation resistance of the ventilation path.

  In this embodiment, as can be understood from FIG. 1, among the plurality of rotating plates 5, 6, 7, 8, the lowermost rotating plate 8 is the rotating plate 5, 6, 7 above the rotating plate 8. Than the diameter.

  That is, according to the present embodiment, the rotary shaft 4 is arranged in the vertical direction in the cylindrical body 3 in which the upper end opening is the air outlet 1 and the lower end opening is the air inlet 2, and the rotary shaft 4 in which a plurality of rotary plates 5 to 8 are fixed at predetermined intervals in the axial direction, that is, the upper end opening of the cylinder 3 is used as the air outlet 1 and the lower end opening is used as the air inlet 2. The size of itself can be reduced, and as a result, miniaturization can be achieved.

  Further, when the cylindrical body 3 is made small, that is, the diameter thereof is reduced, if a plurality of rotary plates 5 to 8 are provided therein, the ventilation resistance is increased, and as a result, the blower connected to the air inlet 2 of the cylindrical body 3 In this embodiment, the lowermost rotary plate 8 of the plurality of rotary plates 5 to 8 is the same as the lower rotary plate 8 in the present embodiment. The diameter is made smaller than the upper rotating plates 5-7.

  If this point is further described, in the present embodiment, since the liquid is supplied from the liquid supply unit 9 to the upper surface of the upper rotating plate 5, the upper rotating plates 5 to 7 are centrifugally separated. Although it is not preferable to reduce the diameter in order to increase the force, the lowermost rotating plate 8 uses the centrifugal force to generate a very small amount of water that could not be refined by the upper rotating plates 5 to 7. What is necessary is just to refine | miniaturize and it becomes possible to make the diameter small.

  And just by reducing the diameter of the lowermost rotary plate 8 in this way, it becomes possible to greatly reduce the airflow resistance in the cylindrical body 3, which prevents the above-described expansion of the capacity of the blower, As a result, downsizing can be achieved.

  Further, even if the diameter of the lowermost rotating plate 8 is reduced in this way, as described above, the amount of liquid supplied here is very small in the first place, so the amount of liquid scattered from the outer peripheral surface is small, With such a small amount of scattering, air is blown from the blower between the outer peripheral surface of the rotating plate 8 and the inner peripheral surface of the cylindrical body 3 until the scattered liquid collides with the inner surface of the cylindrical body 3. Longer encountering time allows sufficient miniaturization.

  That is, even if the size is reduced, the size reduction can be achieved without reducing the efficiency of liquid miniaturization.

The lower stopper 17 is constituted by a nut, and a bolt groove (not shown) into which the nut is screwed is formed in a lower portion of the lowermost rotating plate 8 of the rotating shaft 4. The tightening direction of the nut (lower stopper 17) that is screwed into the bolt groove formed on the rotating shaft 4 is opposite to the rotating direction of the rotating shaft 4 so as to prevent loosening of the rotational drive.

  Further, on the lower surface side of the upper rotating plates 5, 6, 7, the lower connecting portions 5 a, 6 a, 7 a are provided on the outer peripheral portion of the rotating shaft 4, and on the upper surface side of the lower rotating plates 6, 7, 8. On the outer peripheral portion of the rotating shaft 4, upper connecting portions 6b, 7b, 8b connected to the lower connecting portions 5a, 6a, 7a are provided.

  And the upper side connection part 5b provided in the outer periphery of the rotating shaft 4 on the upper surface side of the uppermost rotating plate 5 is connected to the upper stopper 16, and by these configurations, the rotating plates 5, 6 with respect to the rotating shaft 4 are connected. , 7 and 8 are integrated.

  That is, a rotating shaft is arranged in the vertical direction in a cylindrical body in which the upper end opening is an air outlet and the lower end opening is an air inlet, and a plurality of rotating plates are arranged at predetermined intervals in the axial direction of the rotating shaft. Since the air outlet is fixedly arranged at the upper end opening of the cylinder and the air inlet is distributed at the lower end opening, the size of the cylinder itself can be reduced, and as a result, downsizing is achieved. Will be able to.

  Also, if the cylinder is small, that is, if its diameter is reduced, providing a plurality of rotating plates inside increases the airflow resistance, and as a result, increases the capacity of the blower connected to the air inlet of the cylinder. In the present invention, the lowermost rotary plate of the plurality of rotary plates has a smaller diameter than the upper rotary plate in the present invention. ing.

  If this point is further explained, in the present invention, since the liquid is supplied from the liquid supply unit to the upper surface of the upper rotating plate, the upper rotating plate is used to increase the centrifugal force. However, it is not preferable to reduce the diameter of the lowermost rotating plate, but the lowermost rotating plate only needs to be refined by the centrifugal force of a very small amount of liquid that could not be refined by the upper rotating plate. It can be made smaller.

  And even if the diameter of the lowermost rotary plate is reduced in this way, it becomes possible to significantly reduce the ventilation resistance in the cylinder, which prevents the above-described expansion of the capacity of the blower, resulting in a smaller size. It will be possible to achieve.

  Even if the diameter of the lowermost rotating plate is reduced in this way, as described above, the amount of liquid supplied here is very small in the first place, so the amount of liquid scattered from the outer peripheral surface is also small. With such a small amount of scattering, the time it takes for the air to blow from the blower between the outer peripheral surface of the rotating plate and the inner peripheral surface of the cylindrical body before the scattered liquid collides with the inner surface of the cylindrical body.
