[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonated spring manufacturing apparatus for dissolving a combustion gas containing carbon dioxide gas to obtain hot water or water containing carbon dioxide gas.

[0002]

2. Description of the Related Art Conventionally, this type of carbonated spring manufacturing apparatus has a structure shown in FIG.
There was something like that shown. In the figure, solid arrows indicate the flow direction of hot water and dashed lines indicate the flow direction of combustion gas.

A combustion chamber 1 having an upper end in the vertical direction open to the atmosphere, a combustion means 2 provided on a side surface of the combustion chamber 1 and forming a flame f in a horizontal direction, and a combustion chamber 1 below the combustion means 2 A hot water storage chamber 3 that is connected and stores hot water, a water supply passage 4 that supplies water downward from above in the combustion chamber 1, and a hot water storage chamber that supplies hot water stored in the hot water storage chamber 3 to a predetermined location. The hot water supply path 5 is connected to the hot water supply path 3, and the transfer device 6 is provided in the middle of the hot water supply path 5. Then, the water is discharged into the combustion chamber 1 through the water supply passage 4 and the flame f formed by the combustion means 2 is formed.
And heat exchange with the carbon dioxide in the combustion gas. The hot water falls vertically downward and is stored in the hot water storage chamber 3, and then supplied to a predetermined location by the transport device 6 via the hot water supply path 5.

[0004]

However, in the above configuration, the hot water storage room 3 is provided and the hot water storage room 3 is provided.
A transport device 6 for transporting the hot water stored in the apparatus is required, and the equipment volume becomes very large. In addition, the flow rate is insufficient at the time of hot water supply to the second floor or the like because it is cut off from the water supply, and a large flow rate transfer device 6 is required to compensate for the shortage. Further, since water is sprayed into the combustion chamber 1 to perform heat exchange, combustion becomes extremely unstable. Further, there is a danger that the level of the hot water in the hot water storage chamber 3 rises and the combustion means 2 is flooded with the hot water being stored. Further, since carbon dioxide in the combustion gas is dissolved in water under the atmospheric pressure in the combustion chamber 1, there is a problem that the dissolving efficiency is low and the concentration of dissolved carbon dioxide is low.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and provides a carbonated spring which is compact and inexpensive and has a high concentration of dissolved carbonic acid in hot water to increase blood flow as a medical effect. The purpose is to ensure safety in the event.

[0006]

In order to solve the above-mentioned problems, a carbonated spring manufacturing apparatus according to the present invention comprises: a hot water supply passage for passing hot water or water; a combustion gas introduction passage for passing a combustion gas containing carbon dioxide; The combustion gas supplied from the gas introduction path was introduced into the water supply hot water supply path, and the combustion gas introduction means provided in the water supply hot water supply path for dissolving carbon dioxide in the combustion gas was not dissolved in the hot water or water and the hot water or water. A gas-liquid separator provided downstream of the water supply and hot water supply path of the combustion gas introducing means for separating the residual combustion gas, a discharge path for discharging the residual combustion gas separated by the gas-liquid separation means from the gas-liquid separator, A backflow preventing means is provided in the combustion gas introduction passage for preventing backflow of hot water or water from the passage.

[0007]

According to the present invention, by the above means, the combustion gas containing carbon dioxide is introduced into the combustion gas introduction means via the combustion gas introduction path. On the other hand, hot water or water is supplied to the combustion gas introducing means via a hot water supply channel. Hot water or water is mixed with the combustion gas in the combustion gas introducing means, and heat exchange is performed. At the same time, highly water-soluble carbon dioxide in the combustion gas is dissolved to obtain hot water or water containing carbon dioxide gas. Thereafter, the residual combustion gas not dissolved and the hot water or water in which the carbon dioxide gas is dissolved are separated by the gas-liquid separation means, and the residual combustion gas is discharged from the gas-liquid separation means via the discharge path. Hot water or water containing carbon dioxide gas exits from the gas-liquid separation means and is supplied to a predetermined location such as a shower or a bath via a hot water supply channel. In the combustion gas introduction path, since there is provided a means for preventing backflow of hot water or water from the combustion gas introduction means in the middle of the combustion gas introduction path, no hot water or water enters the combustion gas introduction path.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawing, solid arrows indicate the flow direction of hot water or water, dashed arrows indicate the flow direction of combustion gas, and dashed lines indicate signal lines. The same components are denoted by the same reference numerals.

FIG. 1 is a schematic configuration diagram of a main part of an embodiment in which a carbonated spring manufacturing apparatus according to the present invention is applied to a water heater. Reference numeral 7 denotes combustion means for mixing and supplying air supplied by a combustion fan 8 for supplying air for combustion and fuel supplied by a fuel transfer pipe 9. The combustion chamber 10 and the heat exchanger 11 are arranged in the downstream of the combustion means 7 in the flow direction of the combustion gas.
And an exhaust path 12 are connected to each other. Reference numeral 13 denotes a hot water supply or hot water supply passage through which water flows. The heat exchanger 11 is provided in the water supply hot water supply passage 13. The water supplied by the hot water supply path 13 is subjected to heat exchange in the heat exchanger 11 to become hot water, and is discharged from the heat exchanger 11. In the middle of the exhaust passage 12, the combustion gas introduction passage 1 is provided so that a part of the combustion gas flows.
4 is provided branching from the exhaust path 12. On the downstream side of the heat exchanger 11 of the water supply hot water supply channel 13, a direct pressure type edging device 15 is provided. When hot water or water flows backward in the water supply hot water supply channel 13, the backflow is prevented. Hot water or water is supplied at the supply pressure upstream of the vessel 15. Downstream of the direct pressure type edger 15, there is provided combustion gas introduction means 16 for introducing combustion gas from the exhaust path 12 through the combustion gas introduction path 14 and mixing it into hot water or water.
Further, a gas-liquid separation unit 17 for separating the combustion gas and hot water or water is provided downstream of the combustion gas introduction unit 16. The gas-liquid separating means 17 and the exhaust path 12 are communicated by a discharge path 18. Backflow prevention means 19 is provided in the combustion gas introduction path 14 so that hot water or water introduced into the combustion gas introduction means 17 does not flow back to the exhaust path 12 via the combustion gas introduction path 14. In this example,
A check valve 20 is provided as one means of the backflow prevention means 19.

FIG. 2 shows an example of the combustion gas introducing means 14. Reference numeral 21 denotes a hot water supply inlet which is connected to the direct pressure type edger 15. A hot water supply outlet 22 is connected to the gas-liquid separation means 17. Reference numeral 23 denotes a nozzle, 24 denotes a venturi, and 25 denotes a combustion gas inlet which is connected to the combustion gas introduction passage 14.

In the above configuration, the air supplied by the combustion fan 8 and the fuel supplied by the fuel transfer pipe 9 are mixed by the combustion means 7 to form a flame f in the combustion chamber 10. The combustion gas generated by the flame f exchanges heat with the water supplied from the hot water supply path 13 in the heat exchanger 11, and the combustion gas is cooled to a low temperature and exhausted from the exhaust path 12. A part of the combustion gas is guided to the combustion gas introduction means 16 via a combustion gas introduction path 14 which is provided by branching from the middle of the exhaust path 12.

On the other hand, the water supplied to the heat exchanger 11 becomes hot water and enters the direct pressure type edger 15. In the direct pressure type edger 15, when hot water flows backward in the hot water supply channel 13, backflow is prevented. When there is no reverse flow, hot water flows in the hot water supply channel 13 while maintaining the supplied pressure. Thereafter, the hot water is sent to combustion gas introduction means 16 provided on the downstream side of the hot water supply channel 13 of the direct pressure type edger 15. Combustion gas conveying means 19
The combustion gas conveyed in a large amount by the combustion gas inlet 25 of the combustion gas introduction means 16 through the combustion gas introduction passage 14
And stays around the nozzle 23. In the combustion gas introducing means 16, the hot water is spouted from the nozzle 23 at high speed by the hot water supply pressure, and enters the venturi 24. At this time, the venturi 24 becomes negative pressure due to the ejector effect, and the combustion gas around the nozzle 23 is sucked into the venturi 24. Combustion gas introduction means 16
A large amount of combustion gas is mixed into the hot and cold water in the hot and cold water supply passage 13 due to the two synergistic effects of the high-pressure combustion gas conveyed to the nozzle and the ejector effect provided by the nozzle 23 and the venturi 24. The hot water and the combustion gas that have entered the venturi 24 come into direct contact with the hot water in the venturi 24 and in the water supply hot water supply passage 13 leading to the gas-liquid separation means 17, and the highly water-soluble carbon dioxide in the combustion gas is converted into the hot water. And heat exchange with the combustion gas is performed. Residual combustion gas, which is the remainder of the combustion gas not dissolved in the hot water, enters the gas-liquid separation means 17 and is separated from the hot water, stays in the gas-liquid separation means 17 and stays in the exhaust path 12 via the discharge path 18. Return. On the other hand, the hot water whose temperature has risen due to the dissolution of the carbon dioxide exits the gas-liquid separation means 17 and is supplied to the shower or bathtub through the water supply hot water supply path 13.

Since the check valve 20, which is the backflow prevention means 19, is provided in the middle of the combustion gas introduction path 14, the combustion gas introduction path 14 is one-way passage of the combustion gas, and the hot water in the combustion gas introduction means 16 is discharged. , Does not enter the exhaust passage 12 or the combustion means 7 via the combustion gas introduction passage 14.

With such a configuration, the combustion gas is introduced using the water supply pressure, so that the conventional transportation means 6 and hot water storage chamber 3 are not required, and the equipment can be made compact. Further, since the combustion gas is directly dissolved under a high water supply pressure, carbon dioxide can be efficiently dissolved.

Further, since the backflow preventing means 19 is provided in the middle of the combustion gas introduction path 14, the combustion gas introduction path 14 becomes one-way passage of the combustion gas, and the hot water in the combustion gas introduction means 16 is removed. , The hot water containing carbon dioxide gas is always supplied stably without causing misfiring during hot water supply or instability of the combustion by disturbing the hot water supply. You can do it.

The hot water in which the carbon dioxide gas is dissolved is supplied to a bath or shower, and exerts a heat retaining effect, a fatigue recovery effect, a blood pressure stabilizing effect, and a wound healing effect on the human body by an action of increasing blood flow. Furthermore, since the combustion gas and hot water come into direct contact,
The latent heat of water vapor in the combustion gas can also be recovered and the efficiency can be increased. Further, since carbon dioxide in the combustion gas is dissolved, the emission of carbon dioxide, which causes global warming, can be suppressed. In the above embodiment, the case where carbon dioxide is mixed in hot water has been described. However, the present invention is also applicable to the case where carbon dioxide is mixed in water.
The burner 7 in the above needs to be structured so as not to heat the heat exchanger 11.

[0017]

As described above, in the carbonated spring manufacturing apparatus of the present invention, the following effects can be obtained. (1) Since the combustion gas is introduced directly into the hot water flowing through the hot and cold water supply channels to dissolve the carbon dioxide, the hot water storage room and transport means required by the conventional technology are not required, and the equipment is made very compact. Can be done. Also, since hot water or water can be transported directly using hot water or water supply pressure, the hot water or water can be transported to the second floor or the like without transport means. Further, since the combustion gas is directly dissolved under a high water supply pressure, carbon dioxide can be efficiently dissolved. (2) Also, when hot water or water is used, the backflow is prevented even if the pressure in the hot water supply channel increases for some reason and the hot water or water enters the combustion gas introduction channel from the combustion gas introduction means. Means prevent backflow of hot water or water and prevent hot water or water from escaping from the combustion gas introduction channel, so always ensure stable supply of hot water or water containing carbon dioxide gas and ensure safety in use. Can be done. (3) In addition, hot water containing carbon dioxide gas is supplied to baths and showers, and by taking the hot water, it keeps the human body warm,
It exerts a fatigue recovery effect, a blood pressure stabilizing effect, and a wound healing effect. Since the carbon dioxide in the combustion gas is dissolved, the emission of carbon dioxide, which causes global warming, can be reduced. Since the hot water or the water and the combustion gas are in direct contact with each other, the latent heat of water vapor in the combustion gas can also be recovered, and high efficiency can be achieved.
