Description

The present invention relates to a bath gas dissolution production apparatus for easily obtaining a physiologically effective carbonated spring or the like for home use or business use.

  When bathing in warm water containing carbon dioxide gas such as carbonated springs, the bathing effect such as vasodilation and difficulty in cooling hot water is generally well known, and drugs and devices that can obtain bath carbonated water are commercially available.

  As a method for obtaining hot carbonated water containing carbon dioxide, a method is known in which carbonated acid and carbonate that generate carbon dioxide by a chemical reaction are formed into tablets, and the tablets are poured into warm water to obtain hot carbonated water. (Patent Document 1).

Moreover, the carbonated water manufacturing apparatus which dissolves a carbon dioxide gas by passing the water in a water tank to a carbon dioxide addition part with a submersible pump is known (patent document 2).

  However, although the method of Patent Document 1 can obtain carbonated water by a simple operation of simply inserting a tablet, since a drug is directly introduced into water, a reaction by-product other than carbon dioxide gas or tableting is performed. For this reason, there is a drawback that impurities such as molding aids remain in water.

  Further, the method of Patent Document 2 uses a hollow fiber membrane in a dissolver that dissolves carbon dioxide gas in warm water. Carbon dioxide gas is brought into contact with warm water through the membrane surface of the hollow fiber membrane so that the carbon dioxide gas is blown into the warm water all at once. Since it can be dissolved, it can be produced in a short time. However, there is a drawback that the dissolution efficiency is low and it is difficult to achieve a high concentration, and further improvement of the dissolution efficiency has been demanded.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a gas dissolution production apparatus for bath that can easily obtain high dissolution efficiency, that is, high-concentration carbonated water in a short time.

  The second carbon dioxide gas dissolving portion 24 connected to the discharge port 26 of the first carbon dioxide gas dissolving portion 21 and the primary side 27a of the outer flow path 27 described later has the first carbon dioxide gas dissolving portion 21 inside. The outer flow path 27 in which the pipe material 28 is wound in a coil shape, the primary side 29a is connected to the secondary side 27b of the outer flow path 27, and is arranged inside the outer flow path 27. And an inner flow path 29 wound in a reverse coil shape, and the secondary side 29b of the inner flow path 29 is connected to a bathtub side carbonated water discharge port 30 provided in the bathtub 12.

  As the pipe member 28, a bellows-like flexible pipe made of stainless steel is used. This is one in which concaves having an arcuate cross section and convexes having an arcuate cross section are continuously repeated in the longitudinal direction on the inner diameter side, that is, the inner peripheral surface. Thus, a crest 28A, which is a concave recess having an enlarged diameter along the longitudinal direction of the tube material 28, and a trough 28B, which is a convex protrusion having a reduced diameter, are continuously arranged.

  The flexible tube used in this embodiment has a maximum inner diameter A corresponding to the peak portion 28A = 10 to 30 mm (preferably 15.9 mm), and a minimum inner diameter B corresponding to the valley portion 28B = 8 to 28 mm (preferably 12.4 mm), peak height C = (A−B) / 2 mm.

To describe the operation of the above configuration, the remote control 11 is operated to operate the liquid feed pump 16 connected to the control panel 12, and the hot water W in the bathtub 13 is sucked from the bathtub side water supply port 14 by the liquid feed pump 16. Then, the warm water W is guided to the first carbon dioxide gas dissolver 4. Further, the electromagnetic valve 10 controlled by the control panel 12 is opened, and the carbon dioxide gas G from the carbon dioxide gas cylinder 6 is introduced from the carbon dioxide gas inlet 7 to the first carbon dioxide gas dissolver 4 and dissolved in the hot water W.

  At this time, the carbon dioxide gas G is heated by a heater provided in the gas regulator 9 controlled by the control panel 12, thereby preventing the carbon dioxide gas G from becoming dry ice in the carbon dioxide gas cylinder 6 and the carbon dioxide gas supply line 8. In this embodiment, the flow rate of water W is 28.5 L / min (preferably 9.5 L / min), and the flow rate of carbon dioxide G is 7.5 L / min (preferably 2.5 L / min). .

  The hot water W introduced into the first carbon dioxide gas dissolver 4 and dissolved with the carbon dioxide gas G passes through the connecting line 20 and passes through the first melt portion 21 of the second carbon dioxide gas dissolver 5 to the second melt portion 24. The carbon dioxide gas G is further dissolved and returned to the bathtub 13 from the bathtub side carbonated water discharge port 30. By repeating this, the carbon dioxide dissolution concentration of the carbonated water T gradually increases. Moreover, it can also be used to circulate for the purpose of replenishing the carbonated water T in which the carbon dioxide dissolution concentration in the bathtub 13 is lowered with new carbon dioxide G.

At that time, by repeating contact with the stirring barrier 25, the dissolution of the hot water W and the carbon dioxide gas G in the carbonated water T is promoted, and the carbonated water T having an increased free carbonated water concentration is discharged from the outlet 26. The large bubbles of carbon dioxide G introduced into the container 22 without being dissolved in the hot water W in the carbonated water T are stopped by the stirring barrier 25 and finely crushed by the flow of the carbonated water T flowing later. Returned to the flow of water T.

  Next, the operation of the second carbon dioxide gas dissolving part 24 of the second carbon dioxide gas dissolving device 5 will be described in detail. The carbonated water T flowing from the first carbon dioxide gas dissolving part 21 is introduced from the outer flow path 27 to the inner side. Since the carbonated water T passes through the flow path 29 and is discharged into the bathtub 13, but the carbonated water T passes through the bellows-like tube material 28 wound in a coil shape, the carbonated water T is given centripetal force and centrifugal force. In the flow path R inside 28, the carbonated water T mixed with bubbles of carbon dioxide G flows while rotating with great momentum, and the bubbles of carbon dioxide G having a specific gravity lighter than that of the hot water W are collected on the center side of the flow path R. The hot water W is collected outside the flow path R. The bubbles of carbon dioxide G collected on the center side of the pipe material 28 are stopped by the bellows-like folds inside the pipe material 28, and are finely crushed by the flow of the carbonated water T coming later, and returned to the flow of the carbonated water T. It is. That is, the carbonated water T in which the bubble carbon dioxide G is mixed is stirred at high speed inside the pipe 28 of the second carbon dioxide gas dissolving portion 24, and the bubbles of the carbon dioxide gas G are dissolved in the carbonated water T to increase the concentration of dissolved carbon dioxide gas.

The gas dissolver 24 formed in this manner is stirred by centrifugal force to dissolve the gas G in the liquid W, and the gas G can be reliably dissolved in the liquid W with a simple structure. Further, since the outer flow path 27 and the inner flow path 29 are formed by folding the coil-shaped flow path, the bath gas dissolution production apparatus 1 can be reduced in size.
