DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[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. The solid arrows in the drawing indicate the flow direction of hot water, and the broken arrows indicate the flow direction of combustion gas.

[0003] A hot water supply channel 1 through which hot water or water passes, an introduction channel 2 through which a gas containing carbon dioxide passes, and a gas supplied from the introduction channel 2 are introduced into the hot water supply channel 1 and the carbon dioxide contained in the gas is introduced. A mixer 3 provided in the middle of a hot water supply channel 1 for dissolving carbon in hot water or water, and a hot water supply channel 1 for a mixer 3 for separating hot water or water and undissolved gas not dissolved in the hot water or water.
The separator 4 was provided on the downstream side and an air vent 5 for discharging the undissolved gas separated in the separator 4 from the separator 4.

[0004] With the above configuration, the gas containing carbon dioxide is guided to 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 the gas in the mixer 3, and the highly water-soluble carbon dioxide in the gas dissolves into hot water or water containing carbon dioxide gas. Thereafter, the undissolved gas and the hot water or water in which the 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. Also, hot water or water in which carbon dioxide is dissolved exits the separator 4 and is then supplied to a predetermined place via the hot water supply channel 1.

[0005]

However, in the above configuration, the flow rate of the gas that can be introduced into the mixer 3 is proportional to the flow rate of hot water or water flowing through the hot water supply channel 1, so that the general water supply Since the flow rate is small at the water pressure and the flow rate of the gas that can be discharged from the air vent 5 is small,
The flow rate of gas that can be introduced is reduced. Therefore, the concentration of hot water or carbon dioxide dissolved in water has also been reduced. Further, when the pressure loss on the downstream side of the hot water supply water supply channel 1 increases due to the installation situation, the flow rate of the hot water decreases, the back pressure of the mixer 3 increases, the gas suction flow rate in the mixer decreases, and the concentration becomes remarkable. It could go down.

[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 using hot water. May erupt. In addition, when the water supply hot water supply channel 1 is directly connected to a public water supply or the like, if the water supply side becomes negative pressure, there is a problem that hot water containing carbon dioxide gas may flow back to the water supply side.

Next, the carbonic acid concentration in the above configuration 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 gas to be introduced is Qg, the concentration C of carbon dioxide in the hot water is 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. Can be represented.

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

Qg = A · Qw When this equation is substituted into the equation for density, C = F (Qw · A / Qw) = F (A) = const. And the density takes a substantially constant value irrespective of Qw. Therefore, it is presumed that it is difficult to increase the concentration in this configuration.

[0010] The carbonated spring manufacturing apparatus of the present invention solves such a conventional problem, and increases the flow rate of gas introduced per unit flow rate of hot water, increases the concentration of carbonic acid in the hot water, and increases the blood volume obtained by carbonic acid. By improving the medical effects such as the flow increasing action, and by making the separator open to the atmosphere and adopting a configuration that is cut off from the water supply side, it prevents the hot water with dissolved carbonic acid from flowing back into the water supply, and sanitation of the water supply The first object is to ensure the above security.

A second object of the present invention is to increase the flow rate of gas introduced per unit of hot water flow, to increase the concentration of carbonic acid in the hot water, and to enhance medical effects such as blood flow increasing effect obtained by carbonic acid. . By making the separator open to the atmosphere and adopting a configuration that is cut off from the water supply side, it is possible to prevent hot water with dissolved carbon dioxide gas from flowing back into the water supply, to ensure the sanitary safety of the water supply, and to use pumps, etc. The hot water is conveyed by the conveying means, so that hot water having a high carbonic acid concentration can be supplied regardless of the pressure loss on the downstream side. Is to take a bath.

[0013] 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. An object of the present invention is to adjust the tapping flow rate so as to make the outflow rate the same, thereby eliminating flow rate fluctuation and stabilizing the carbon dioxide concentration.

A fourth object of the present invention is to detect the level of 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 so that, for example, a low water pressure Even in areas where the flow rate of hot water supplied to the separator is low, the water level in the separator drops, preventing gas from entering the hot water outlet and discharging gas from the place of use, and using the device. The above is to enhance safety.

A fifth object of the present invention is to detect a water level of hot water stored in a separator and adjust a flow rate of hot water entering the separator according to the water level, for example, to obtain a high water pressure. In areas and the like, even if the flow rate of hot water supplied to the separator is large, the water level in the separator rises to prevent hot water from overflowing from the separator, and to improve the safety in use of the device. .

It is provided with control means for controlling the flow rate adjusting means.

[0020]

According to the present invention, hot water is supplied to the separator from the hot water supply channel by the first technical means. The hot water stored in the separator flows through 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. The highly water-soluble carbon dioxide in the gas is dissolved in the hot water, and the hot water becomes hot water containing carbonic acid. The undissolved gas and the hot water that are not dissolved in the hot water are separated in the separator, the undissolved gas is discharged through the discharge path, and only the hot water containing carbonic acid is supplied to the predetermined place through the hot water path. .

Since the mixer is provided in a separate circulation circuit not directly connected to the hot water supply path or the hot water supply path for supplying hot water, the flow rate of the gas introduced is determined by the flow rate of the hot water flowing through the hot water supply path or the hot water supply path. Is proportional to the circulating flow rate flowing through the circulation circuit. Since the circulating flow rate is determined by the capacity of the conveying means provided, the higher the capacity of the conveying means, the higher the flow rate of the introduced gas and the higher the concentration.
Also, since the separator is open to the atmosphere through the exhaust path, even if the hot water supply path is directly connected to the water supply, the hot water supply path is cut off from the hot water stored in the separator, and the hot water supply path is Even when the pressure is increased, the hot water containing carbonic acid stored in the separator does not flow back into the hot water supply path.

Here, the carbonic acid concentration in the hot water will be described using mathematical expressions. The flow rate of hot water flowing in the hot water supply path and the hot water supply path is Qw, and the flow rate of hot water flowing in the circulation circuit (circulation flow rate) is Q.
Assuming that j is the flow rate Qg of the gas to be introduced, the concentration C of carbonic acid 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 proportionality constant between Qg and Qw is A, the following equation is obtained.

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

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

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 through 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. The highly water-soluble carbon dioxide in the gas is dissolved in the hot water, and the hot water becomes hot water containing carbonic acid. The undissolved gas and the hot water that are not dissolved in the hot water are separated in the separator, the undissolved gas is discharged through the discharge path, and only the hot water containing carbonic acid is supplied to the predetermined place through the hot water path. . The hot water stored in the separator is discharged at a high pressure by a conveying means from a hot water passage branched from a circulation circuit.

Since the mixer is provided in a separate circulation circuit that is not directly connected to the hot water supply path or hot water supply path for supplying hot water, the flow rate of the introduced gas depends on the flow rate of hot water flowing through the hot water supply path or hot water supply path. Is proportional to the circulating flow rate flowing through the circulation circuit. Since the circulating flow rate is determined by the capacity of the conveying means provided, the higher the capacity of the conveying means, the higher the flow rate of the introduced gas and the higher the concentration.
Also, since the separator is open to the atmosphere through the exhaust path, even if the hot water supply path is directly connected to the water supply, the hot water supply path is cut off from the hot water stored in the separator, and the hot water supply path is Even when the pressure is increased, the hot water containing carbonic acid stored in the separator does not flow back into the hot water supply path. Furthermore, since the hot water path is provided by branching from the circulation circuit downstream of the conveying means, the hot water is forcibly supplied to a predetermined location, so that even if the pressure loss becomes large downstream of the hot water path due to installation conditions or the like. , A stable flow rate can be secured.

In a third technical means of the present invention,
The flow rate of the hot water flowing in the hot water path is controlled by flow rate adjusting means provided in the middle of the hot water path in accordance with the flow rate obtained from the inlet flow rate detecting means and the information obtained from the discharge flow rate detecting means. For example,
By controlling the flow rate adjusting means provided in the hot water supply path so that the flow rate of hot water entering the separator via the hot water supply path and the flow rate of hot water leaving the separator via the hot water supply path are the same,
By keeping the water level in the separator constant, eliminating fluctuations in the flow rate of hot water, and stabilizing the flow rate in the circulation circuit, stabilizing the flow rate of gas introduced into the mixer, The carbonic acid concentration can be stabilized.

In a fourth technical means of the present invention,
The flow rate of hot water flowing in the hot water supply path is controlled by flow rate adjusting means provided in the middle of the hot water supply path in accordance with information obtained from the water level detecting means for detecting the water level of the hot water in the separator. For example, in a low water pressure area or the like, the flow rate of hot water supplied to the separator is small, so that the water level in the separator decreases, and gas may be mixed into the circulation path or the hot water path. However, when the water level detecting means detects that the water level in the separator has dropped below a predetermined value, the water level is controlled by controlling the flow rate adjusting means so as to reduce the flow rate of the hot water flowing out of the hot water path. It is possible to prevent the gas from falling below the value, to prevent gas from being mixed into the circulation path or the hot water path, and to ensure safety in using the apparatus.

In a fifth technical means of the present invention,
The flow rate of the hot water flowing in the hot water supply path is controlled by flow rate adjusting means provided in the middle of the hot water supply path according to the information obtained from the water level detecting means for detecting the water level of the hot water in the separator. For example, in a high water pressure area or the like, the flow rate of hot water supplied to the separator is large, so that the water level in the separator rises, and the hot water containing carbonic acid may overflow through the discharge path. However, if the water level detecting means detects that the water level in the separator has risen 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 path to the separator. Thereby, 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 secure the safety in using the apparatus.

Further, since the separator 19 is communicated with the discharge path 25 and is open to the atmosphere, the hot water supply path 17 is cut off from the hot water stored in the separator 19, and the hot water supply path 17 is in a negative pressure state. Also, the hot water containing carbonic acid stored in the separator 19 does not flow back to the hot water supply passage 17.

In the above configuration, the hot water in which the carbonic acid is dissolved circulates in the circulation circuit 22, and a part of the hot water is sent from the downstream side of the conveying means 23 to a predetermined location through the hot water passage 20. Since the hot water flowing out of the hot water path 20 is sent at a high pressure by the transport means 23, even if the pressure loss due to the positional relationship between the bathtub 21 and the apparatus or the installation condition such as the length of the hot water path 20 changes slightly, the hot water flows to the separator 19. Hot water can be supplied stably without the hot water flowing backward and the flow rate of the supplied hot water does not significantly change.

As described above, according to the carbonated spring manufacturing apparatus of the present invention, the following effects can be obtained.

According to the first aspect of the present invention, by circulating a large amount of hot water in the separator using the transport means, a large amount of combustion gas can be introduced into the circulation circuit, and the hot water can be discharged from the hot water path. The concentration of carbonic acid in hot water can be increased, and a high blood flow increasing effect can be obtained by bathing. In addition, the separator is opened to the atmosphere via the discharge channel, and the hot water supply channel and the separator are separated to prevent backflow of hot water containing carbonic acid in the hot water supply channel and ensure sanitary safety. You can do it.

According to the second aspect of the invention, a large amount of combustion gas can be introduced into the circulation circuit by circulating a large amount of hot water in the separator by using the conveying means, and the hot water can be discharged from the hot water path. The concentration of carbonic acid in hot water can be increased, and a high blood flow increasing effect can be obtained by bathing. In addition, the separator is opened to the atmosphere via the discharge channel, and the hot water supply channel and the separator are separated to prevent backflow of hot water containing carbonic acid in the hot water supply channel and ensure sanitary safety. You can do it. Further, since the hot water discharged from the hot water path is sent at a high pressure by the conveying means, the hot water flows back to the separator even if the pressure loss is slightly changed due to the positional relationship between the bathtub and the apparatus or the installation condition such as the length of the hot water path. In addition, a stable supply of hot water can be achieved without significantly changing the flow rate of the supplied hot water.

According to the third aspect of the present invention, for example, the flow rate of hot water entering the separator via the hot water supply path is the same as the flow rate of hot water exiting the separator via the hot water supply path. By controlling the flow rate adjusting means provided in the hot water supply path, the water level in the separator is kept constant, the fluctuation of the flow rate of the hot water is eliminated, and the flow rate in the circulation circuit is stabilized. Stabilizes the flow rate of the gas introduced into the hot water to stabilize the carbon dioxide concentration in the hot water.

According to the fourth aspect of the present invention, for example, in a low water pressure area, the flow rate of hot water supplied to the separator is small, so that the water level in the separator drops, and gas is mixed into the circulation path and the hot water 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 water level is controlled by controlling the flow rate adjusting means so as to reduce the flow rate of the hot water flowing out of the hot water path. It is possible to prevent the gas from falling below the value, to prevent gas from being mixed into the circulation path or the hot water path, and to ensure safety in using the apparatus.

According to the fifth aspect of the present invention, for example, in a high water pressure area, the flow rate of hot water supplied to the separator is large, so that the water level in the separator rises, and the hot water containing carbonic acid flows through the discharge passage. May overflow. However, if the water level detecting means detects that the water level in the separator has risen 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 path to the separator. Thereby, 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 secure the safety in using the apparatus.
