Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonated spring producing apparatus for dissolving carbon dioxide-containing gas in hot water to produce hot water containing carbonic acid.

[0002]

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

A water supply hot water supply passage 1 through which hot water or water passes, an introduction passage 2 through which a gas containing carbon dioxide passes, and a gas supplied from the introduction passage 2 is introduced into the water supply hot water supply passage 1, and the carbon dioxide contained in the gas is introduced. Mixer 3 provided in the middle of water supply hot water supply passage 1 for dissolving carbon in hot water or water, and water supply hot water supply passage 1 for mixer 3 for separating hot water or water and undissolved gas not dissolved in hot water or water
It was composed of a separator 4 provided on the downstream side and an air vent 5 for discharging the undissolved gas separated in the separator 4 from the separator 4.

With the above structure, the gas containing carbon dioxide is introduced into the mixer 3 from the introduction path 2. On the other hand, hot water or water is supplied to the mixer 3 via the hot water supply channel 1. Hot water or water is mixed with gas in the mixer 3, and carbon dioxide having high water solubility in the gas is dissolved to become hot water or water containing carbon dioxide gas. After that, the undissolved gas that has not been dissolved and the hot water or water in which carbon dioxide is dissolved are separated in the separator 4, and the undissolved gas is discharged from the separator 4 via the air vent 5. Further, the hot water or water in which carbon dioxide is dissolved is supplied to a predetermined place via the water supply hot water supply passage 1 after leaving the separator 4.

[0005]

However, in the above configuration, the flow rate of the gas that can be introduced in the mixer 3 is proportional to the flow rate of the hot water or the water flowing through the hot water supply hot water supply passage 1, and therefore the supply of general water supply is not possible. Since the flow rate is small under water pressure and the flow rate of gas that can be discharged from the air vent 5 is small,
The flow rate of gas that can be introduced decreases. Therefore, the concentration of hot water or carbon dioxide dissolved in water was also low. Further, when the pressure loss on the downstream side of the hot water supply channel 1 increases depending on the installation situation, the hot water outlet flow rate decreases, the back pressure of the mixer 3 increases, the gas suction flow rate in the mixer decreases, and the concentration is significantly increased. There were times when it dropped.

[0006] When the level of the hot water in the separator 4 drops, the gas in the separator 4 enters the hot water supply channel 1 and the gas flows together from the outlet of the hot water supply channel 1 that uses hot water. There was a gush. Further, when the hot water supply channel 1 is directly connected to a public water supply or the like, if there is a negative pressure on the water supply side, the hot water containing carbon dioxide gas may flow back to the water supply side.

Next, the carbon dioxide concentration in the above structure will be described using mathematical expressions. Assuming that the flow rate of the hot water flowing through the hot water supply channel 1 is Qw and the flow rate of the introduced gas is Qg, the carbon dioxide concentration C in the hot water is a function proportional to the ratio of the gas flow rate and the hot water flow rate as shown in the following equation. Can be represented.

C = F (Qg / Qw) However, since Qg has a relationship almost proportional to Qw,
Assuming that the proportional constant of Qg and Qw is A, the following equation is obtained.

Qg = AQw When this equation is substituted into the concentration equation, C = F (QwA / Qw) = F (A) = const. Therefore, the concentration takes a substantially constant value regardless of Qw. Therefore, it is presumed that it is difficult to increase the concentration with this configuration.

The carbonated spring producing apparatus of the present invention solves such a conventional problem, and increases the flow rate of the gas introduced per unit discharge flow rate to increase the carbonic acid concentration in the hot water to obtain blood obtained by carbonic acid. By increasing the medical effects such as the flow increasing action and by making the separator open to the atmosphere and taking a structure that is cut off from the water supply side, it is possible to prevent the hot water in which carbonic acid is dissolved from flowing back into the water supply and to improve the sanitation of the water supply. The first purpose is to ensure the above safety.

A second object of the present invention is to increase the flow rate of gas introduced per unit flow rate of hot water, increase the carbonic acid concentration in hot water, and enhance the medical effects such as blood flow increasing action obtained by carbonic acid. . By making the separator open to the atmosphere and taking a structure that is cut off from the water supply side, it is possible to prevent the hot water in which carbon dioxide gas is dissolved from flowing back into the water supply, and to ensure the sanitary safety of the water supply, as well as pumps, etc. The hot water having a high carbon dioxide concentration is supplied regardless of the pressure loss on the downstream side by transporting the hot water by the transporting means, and even if the installation condition of the device or the pressure loss on the downstream side of the device changes, the hot water has a stable flow rate. Is to take out hot water.

A third object of the present invention is to detect the flow rate of hot water entering the separator and the flow rate of hot water exiting the separator, and for example, to detect the flow rate entering the separator and the separator. By adjusting the flow rate of tapping hot water so that the flow rate is the same, the flow rate fluctuation is eliminated and the carbon dioxide concentration is stabilized.

A fourth object of the present invention is to detect the water level of the hot water stored in the separator and adjust the flow rate of the hot water flowing out of the separator according to the water level. Even if the flow rate of hot water supplied to the separator is low in areas such as the area, the water level inside the separator is prevented from lowering and gas intrudes into the hot water discharge passage to prevent the gas from spouting from the place of use and using the device. It is to improve the safety above.

A fifth object of the present invention is to detect the water level of the hot water stored in the separator and adjust the flow rate of the hot water entering the separator in accordance with the water level, for example, to obtain a high water pressure. This is to prevent the hot water from overflowing from the separator by raising the water level in the separator even when the flow rate of the hot water supplied to the separator is high in the area, etc., and to enhance the safety in use of the device. .

[0020]

According to the present invention, hot water is supplied from the hot water supply passage to the separator by the above-mentioned first technical means. The hot water stored in the separator flows in the circulation circuit by the conveying means and returns to the separator via the mixer. In the mixer, the gas containing carbon dioxide supplied from the introduction path is introduced into the circulation circuit, and the hot water and the gas are mixed. Highly water-soluble carbon dioxide in the gas is dissolved in hot water, and the hot water contains carbonic acid. The undissolved gas that was not dissolved in the hot water and the hot water are separated in the separator, the undissolved gas is discharged through the discharge passage, and only the carbon dioxide-containing hot water is supplied to the prescribed place through the discharge passage. .

Since the mixer is provided in a separate circulation circuit which is not directly connected to the hot water supply passage or hot water supply passage for supplying hot water, the flow rate of the gas introduced is the flow rate of hot water flowing through the hot water supply passage or the hot water discharge passage. It is proportional to the circulation flow rate flowing through the circulation circuit regardless of. Since the circulation flow rate is determined by the capacity of the transfer means provided, the higher the capacity of the transfer means, the higher the flow rate of the introduced gas and the higher the concentration.
In addition, since the separator is open to the atmosphere via the exhaust passage, even if the hot water supply passage is directly connected to the water supply, the hot water supply passage is separated from the hot water stored in the separator, and the hot water supply passage is negative. Even if pressure is applied, the hot water containing carbonic acid stored in the separator does not flow back into the hot water supply passage.

Here, the carbonic acid concentration in the hot water will be described using mathematical expressions. Qw is the flow rate of the hot water flowing in the hot water supply passage and the hot water discharge passage, and Q is the flow rate of the hot water flowing in the circulation circuit (circulation flow rate).
j and the flow rate Qg of the introduced gas, the carbon dioxide concentration C in the hot water can be expressed as a function proportional to the ratio of the gas flow rate to the hot water flow rate as shown in the following equation.

C = F (Qg / Qw) However, since Qg has a relationship almost proportional to Qj,
Assuming that the proportional constant of Qg and Qw is A, the following equation is obtained.

Qg = Qj · A When this formula is substituted into the formula of concentration, C = F (A · Qj / Qw), and the concentration is proportional to Qj / Qw. Therefore, the higher the circulation flow rate, the higher the concentration.

Generally, the circulation flow rate Qj can be set to 3 to 4 times the flow rate Qw of the hot water supplied, so that the concentration can also be set to 3 to 4 times the conventional concentration.

Further, in the second technical means of the present invention,
Hot water is supplied to the separator from the hot water supply channel as in the first technical means. The hot water stored in the separator flows in the circulation circuit by the conveying means and returns to the separator via the mixer. In the mixer, the gas containing carbon dioxide supplied from the introduction path is introduced into the circulation circuit, and the hot water and the gas are mixed. Highly water-soluble carbon dioxide in the gas is dissolved in hot water, and the hot water contains carbonic acid. The undissolved gas that was not dissolved in the hot water and the hot water are separated in the separator, the undissolved gas is discharged through the discharge passage, and only the carbon dioxide-containing hot water is supplied to the prescribed place through the discharge passage. . The hot water stored in the separator is discharged at a high pressure from the hot water passage provided by branching into the circulation circuit by the conveying means.

Since the mixer is provided in a separate circulation circuit which is not directly connected to the hot water supply passage or hot water discharge passage for supplying hot water, the flow rate of the introduced gas is the flow rate of hot water flowing through the hot water supply passage or the hot water discharge passage. It is proportional to the circulation flow rate flowing through the circulation circuit regardless of. Since the circulation flow rate is determined by the capacity of the transfer means provided, the higher the capacity of the transfer means, the higher the flow rate of the introduced gas and the higher the concentration.
In addition, since the separator is open to the atmosphere via the exhaust passage, even if the hot water supply passage is directly connected to the water supply, the hot water supply passage is separated from the hot water stored in the separator, and the hot water supply passage is negative. Even if pressure is applied, the hot water containing carbonic acid stored in the separator does not flow back into the hot water supply passage. Further, since the hot water supply path is provided by branching from the circulation circuit on the downstream side of the conveying means, the hot water is forcibly supplied to a predetermined location, so even if the pressure loss becomes large on the downstream side of the hot water supply path due to installation conditions and the like. It is possible to secure a stable flow rate.

In the third technical means of the present invention,
The flow rate of the hot water flowing in the hot water outlet is controlled by the flow rate adjusting means provided in the hot water outlet according to the flow rate obtained from the inlet flow rate detecting means and the information obtained from the outlet flow rate detecting means. For example,
By controlling the flow rate adjusting means provided in the hot water outlet so that the flow rate of hot water entering the separator via the hot water supply passage and the flow rate of hot water leaving the separator via the hot water supply passage are the same,
By keeping the water level in the separator constant, eliminating fluctuations in the flow rate of hot water discharged, and stabilizing the flow rate in the circulation circuit, the flow rate of gas introduced into the mixer is stabilized and The carbon dioxide concentration can be stabilized.

In the fourth technical means of the present invention,
According to the information obtained from the water level detecting means for detecting the water level of the hot water in the separator, the flow rate adjusting means provided in the hot water outlet controls the flow rate of the hot water flowing in the hot water outlet. For example, in a low water pressure area or the like, since the flow rate of hot water supplied to the separator is small, the water level in the separator may drop, and gas may be mixed into the circulation path or the hot water exit path. However, when the water level detecting means detects that the water level in the separator has dropped below a predetermined value, the flow level adjusting means is controlled so as to reduce the flow rate of the hot water flowing out of the hot water outlet passage, thereby controlling the water level to a predetermined level. It is possible to suppress falling below the value, prevent gas from mixing in the circulation path or the hot water supply path, and ensure safety in using the device.

Further, in the fifth technical means of the present invention,
According to the information obtained from the water level detecting means for detecting the water level of the hot water in the separator, the flow rate adjusting means provided in the hot water supply path controls the flow rate of the hot water flowing in the hot water supply path. For example, in a high water pressure area or the like, the flow rate of hot water supplied to the separator is high, so that the water level in the separator rises, and hot water containing carbonic acid may overflow through the discharge passage. However, when the water level detecting means detects that the water level in the separator rises above a predetermined value, the flow rate adjusting means should be controlled so as to reduce the flow rate of hot water supplied from the hot water supply passage to the separator. Thus, it is possible to prevent the water level from rising above a predetermined value, prevent the hot water from overflowing through the discharge path, and ensure the safety in using the device.

The concentration of carbon dioxide in hot water can be increased, and a high blood flow increasing action can be obtained by taking a bath or the like. In addition, by opening the separator to the atmosphere through the discharge path and separating the hot water supply path from the separator, it is possible to prevent backflow of hot water containing carbonic acid into the hot water supply path, ensuring hygienic safety. You can do it. Furthermore, since the hot water discharged from the hot water outlet is sent at a high pressure by the transport means, even if the pressure loss due to the positional relationship between the bathtub and the device and the installation conditions such as the length of the hot water outlet pipe changes, the hot water will flow back to the separator. In addition, the flow rate of hot water to be supplied does not change significantly, and stable hot water supply can be achieved.

According to the third aspect of the invention, for example, the flow rate of the hot water entering the separator via the hot water supply passage and the flow rate of the hot water exiting from the separator via the hot water discharge passage are the same. By controlling the flow rate adjusting means provided in the hot water outlet in the mixer, the water level in the separator is kept constant, fluctuations in the flow rate of hot water discharged are eliminated, and the flow rate in the circulation circuit is stabilized, thereby stabilizing the mixer. The concentration of carbon dioxide in the hot water can be stabilized by stabilizing the flow rate of the gas introduced into.

According to the fourth aspect of the invention, for example, in a low water pressure area or the like, since the flow rate of the hot water supplied to the separator is small, the water level in the separator is lowered and gas is mixed in the circulation path and the hot water exit path. It is possible. However, when the water level detecting means detects that the water level in the separator has dropped below a predetermined value, the flow level adjusting means is controlled so as to reduce the flow rate of the hot water flowing out of the hot water outlet passage, thereby controlling the water level to a predetermined level. It is possible to suppress falling below the value, prevent gas from mixing in the circulation path or the hot water supply path, and ensure safety in using the device.

According to the fifth aspect of the invention, for example, in a high water pressure area or the like, since the flow rate of the hot water supplied to the separator is large, the water level in the separator rises and the hot water containing carbonic acid is discharged through the discharge passage. Is likely to overflow. However, when the water level detecting means detects that the water level in the separator rises above a predetermined value, the flow rate adjusting means should be controlled so as to reduce the flow rate of hot water supplied from the hot water supply passage to the separator. Thus, it is possible to prevent the water level from rising above a predetermined value, prevent the hot water from overflowing through the discharge path, and ensure the safety in using the device.
