Description

  The present invention relates to a water supply device that supplies drinking water that is cold water or hot water in a general home or office, and the like, and relates to a water supply device that contains radon components in the supplied drinking water and maintains radon-containing concentration. is there.

  In connection with the health boom, it has been proposed to drink radon water as good for the body and health. Radon water is often obtained from natural hot spring sources, and it is widely distributed by owners of natural radon water, which is springed from the source, in plastic tanks or plastic bottles. ing.

  Radon water is thought to be useful for activating the body's metabolism and improving the antioxidant function. Radon water is also considered to have an intestinal regulating action, and is considered to be one of drinking water useful for maintaining the health and promoting health of modern people. For this reason, it is thought that drinking of radon water has been proposed. For this reason, it is required to be able to drink radon water easily and at low cost at home.

Since radon water is considered to be effective in bathing, techniques for performing hot spring bathing using radon water at home have also been proposed (see, for example, Patent Documents 1 to 3). These patent documents 1-3 are disclosing the technique for obtaining hot spring water. In addition, techniques for modifying natural water and tap water with minerals have been proposed (see, for example, Patent Documents 4 to 6). In addition, the idea of the installation of the mineral for obtaining hot spring water and reformed water is also proposed (for example, refer patent documents 7 and 8).
JP 2008-18157 A JP 2006-34736 A JP 2001-322877 A JP 2007-37661 A JP 2005-329336 A JP 2006-334522 A JP 2004-130155 A JP 2008-6232 A

  However, when radon water taken from a source or obtained from a device that reforms natural water into hot spring water is packed in plastic tanks or plastic bottles and distributed and sold, the radon content of radon water will increase over time. There is a problem that the concentration decreases. Generally, the radon component contained in radon water evaporates in about 3 to 4 days to 1 week. For this reason, radon water drawn from sources packed in plastic tanks and plastic bottles, or obtained by modifying natural water, must be stored in radon during storage, transportation, and household storage. There is a problem that the concentration of content decreases. For this reason, the user who wants to use radon water for health promotion or the like has an undesirable problem that the radon-containing concentration decreases (sometimes disappears) before actually drinking.

  Moreover, even if radium ore is added to natural water (including general water such as tap water), it still takes several days until it is reformed to radon water containing a sufficient radon-containing concentration. For this reason, there is a problem that even if radium ore is immersed in water or hot water at home, the radon water cannot be drunk immediately.

  Furthermore, since the radium ore and the modifier made from this are expensive, there is a problem that they are not suitable for general household use in terms of cost.

  When radon water is used as hot spring water for bathing, fine control of radon content concentration is not necessary, but when radon water is used as drinking water, it is necessary to control the prescribed radon content concentration. Become. For example, radon water having a radon-containing concentration of 5.5 Mache or higher can be displayed as hot spring water, but drinking radon water having this level of radon-containing concentration may cause diarrhea and the like.

  Moreover, when radon water is drunk or used as cold water, the radon-containing concentration is rarely reduced. However, there are many cases where radon water is used as warm water. For example, when radon water, which is warm water, is used to brew tea or coffee. For this reason, radon water containing a radon component in advance may be used in a water feeder or a water server that can supply cold water and hot water. However, when radon water is heated to warm water inside a water supply machine or water server, there is a problem that radon components are reduced. This is because the radon component is considered to dissipate into the outside air due to evaporation of steam from warm water.

  For this reason, when water is heated in a water supply machine or a water server, boiling or generation of steam is considered to be a cause of reduction in the radon-containing concentration of hot water.

  From the above, in order to drink radon water whose radon-containing concentration is adjusted, particularly hot radon water, at low cost and easily at home, it is necessary to solve the following problems.

  (1) When purchasing radon water packed in a container, the radon-containing concentration decreases or disappears during transportation and storage. In particular, radon content decreases when heated to warm water.

  (2) Even if radium ore is immersed in water or hot water, it takes time to be modified to radon water containing radon-containing concentration.

  (3) It is expensive to purchase radium ore to improve water at home. In particular, even if radium ore is added to tap water, there is no sanitary problem because chlorine contained in tap water has a disinfecting ability. There is a hygiene problem.

  (4) When the technology for bathing hot spring water is applied to the reforming of drinking radon water, the radon content is modified so that it is too high or too low.

  (5) Even when radon water is heated inside a water supply machine or water server, the radon component should not be reduced.

  (6) When radon water is stored in a water container of a water supply machine and cold water and hot water are supplied from the water supply machine, the radon component decreases according to a half-life of 3.8 days. The reduction of the radon component due to the half-life is unavoidable, but in the case of hot water, there is a problem that the radon component is reduced at a speed higher than the half-life due to boiling or generation of steam in the hot water tank.

  In particular, conventional water supply machines and water servers have a problem that radon components are reduced faster than half-life due to boiling or steam when making hot water. Alternatively, even when the radium ore body is stored in the hot water tank or the cold water tank, there is a problem that the radon component is reduced earlier than the cold water due to boiling or steam.

  For example, even if radon water is contained in the water tank of a water server or water supply machine, the circulation from the water tank of the water server or water supply machine to the water supply requires a certain amount of time. Concentration decreases.

  Here, Patent Documents 1 to 3 disclose a technique for reforming natural water into hot spring water. Patent Document 1 discloses that hot spring water having hot spring components is reformed by immersing radium ore in water or hot water stretched in a bathtub. Patent Documents 2 and 3 disclose water modifiers produced by firing natural radioactive element minerals together with ceramic raw materials.

  However, since the techniques disclosed in Documents 1 to 3 are modification to hot spring water for bathing, the control of the radon-containing concentration is not considered. In addition, since water and hot water stored in a bathtub or the like are targeted for reforming, there is no consideration for transportation or transportation of radon water. For this reason, the technique which applied the technique of patent documents 1-3 to manufacture of drinking radon water cannot solve the above-mentioned problems (1) to (6).

  Patent Documents 4 to 6 disclose techniques for modifying natural water into functional water. Patent Document 4 discloses a technique for reforming hot spring water using a radium component. Patent Document 5 discloses a technique of modifying a water or a predetermined component by placing a ceramic or ore having a specific component, which is not a radium component, in the middle of a water circulation path. Patent Document 6 discloses a technique for reforming water by storing a catalyst in a water container.

  However, even if the techniques disclosed in Documents 4 to 6 are actually applied to a technique for reforming natural water or tap water into radon water at home, the above problems (2) and (3) cannot be solved.

  Patent Documents 7 and 8 disclose a technique for devising the installation position of minerals for reforming into hot spring water. Patent Document 7 discloses a technique for modifying water into hot spring water by arranging a case in which mineral is stored in accordance with an outlet of water (for example, under a faucet). Patent document 8 is disclosing the technique which arrange | positions the case which stores a mineral in the drain outlet of a bathtub, in order to obtain the hot spring water for bathing.

  However, in Patent Document 7, the contact time between water and mineral is very short, and the modification is not sufficiently performed. That is, Patent Document 7 cannot solve the problem (2). Moreover, patent document 8 is a technique which produces | generates the hot spring water for bathing, Comprising: Although it cannot apply to the production | generation of radon water to drink, even if it can apply temporarily, said problem (4) cannot be solved. In addition, neither of Patent Documents 7 and 8 can solve the problem (3).

  As described above, techniques for generating hot spring water for bathing using radium ore (Patent Documents 1 to 3), techniques for modifying natural water or tap water into functional water (Patent Documents 4 to 6), and hot spring water All of the above problems (1) to (6) cannot be solved at the same time by any of the techniques (Patent Documents 7 to 8) related to the installation position of the mineral for reforming to the above. The same applies even if these techniques are appropriately combined.

  Of course, the prior art cannot prevent the radon component from being lowered (the above problems (5) and (6)) when the radon water is heated to warm water.

  In order to solve the above-described problems, the present invention provides a radon component in drinking water during circulation until a user drinks, particularly in warm water in a water supply device using a water tank that contains radon water or mineral water. It aims at providing the water supply machine which maintains the radon content density of.

  In view of the above problems, the water supply apparatus of the present invention includes a water container for storing water, a transport means for transporting the water stored in the water container by at least one of natural flow and suction, and water transported by the transport means. A cold water tank for temporarily storing the obtained cold water and a heating means for heating the cold water supplied by the pressure difference from the cold water tank, and temporarily storing the obtained hot water A hot water tank and a pipe for supplying cold water from the cold water tank to the hot water tank, and the water contained in the water container is radon water containing a radon component, and the hot water tank is located below the cold water tank. However, a pressure difference is generated between the cold water tank and the hot water tank, and the pipe supplies cold water from the cold water tank to the hot water tank due to the pressure difference.

  The water feeder temporarily stores water transported from a water tank, which is also an exchange cartridge, in storage means (a cold water tank or a hot water tank) in order to make it cold water or hot water. The storage means often has a capacity of several liters or more, and depending on the degree of use, the storage means often stores the same water for several days.

  When the water stored in the water tank is radon water taken, the water supply device of the present invention can maintain the radon-containing concentration of the drinking water to be supplied by the radium ore body provided in the storage means. When the water stored in the water tank is mineral water, the radon component is contained while being stored in the storage means, and drinking water containing the radon component is supplied.

  Moreover, since the water layer of this invention does not produce an air layer in the internal space of a heating tank, even if radon water is heated, a radon component does not volatilize. This is the same whether, for example, radon water is supplied to the water supply device in advance or natural water is supplied.

  Furthermore, since the radon water does not boil inside the heating tank by adjusting the temperature in the heating tank, the radon component does not volatilize.

  Thus, according to the water feeder of the present invention, in most situations, the user can use radon water containing a radon component as potable water in both hot and cold water.

  Further, since the radium ore body is stored in the case, the radium ore body is taken out of the case or removed from the case and washed, so that the cost is reduced.

  The water supply apparatus according to the first aspect of the present invention is transported by a water container for storing water, a transport means for transporting water stored in the water container by at least one of natural flow and suction, and a transport means. It has a cooling means for cooling water, and has a cold water tank for temporarily storing the obtained cold water, and a heating means for heating the cold water supplied by the pressure difference from the cold water tank, and temporarily stores the obtained hot water. A hot water tank and a pipe for supplying cold water from the cold water tank to the hot water tank, and the water contained in the water container is radon water containing a radon component, and the hot water tank is located below the cold water tank. A pressure difference is generated between the cold water tank and the hot water tank, and the pipe supplies water from the cold water tank to the hot water tank due to the pressure difference.

  With this configuration, when radon water is supplied to the cold water tank and the hot water tank, boiling and steam generation cannot occur in the hot water tank, so that the radon component is prevented from decreasing at a speed faster than the half-life. . In particular, since the hot water tank is always full, no steam is generated in the hot water tank, and the radon-containing concentration does not decrease.

  In the water supply apparatus according to the second invention of the present invention, in addition to the first invention, the water contained in the water container is general water, and at least one of the cold water tank and the hot water tank contains the radium ore body. Is possible.

  With this configuration, even when natural water is supplied to the water supply device, the natural water contains a radon component during the period of circulation inside the water supply device. As a result, the water supply can supply radon water. Further, since no air layer is generated in the hot water tank, evaporation in the hot water tank does not occur, and the radon component of the hot water does not decrease.

In the water supply machine according to the third invention of the present invention, in addition to any of the first to second inventions, cold water supply means for supplying cold water from a cold water tank,
A hot water supply means for supplying hot water from the hot water tank;
When hot water is supplied from the hot water supply means and the hot water in the hot water tank decreases, the cold water tank supplies cold water to the hot water tank.

  With this configuration, the inside of the hot water tank is always full, and no steam is generated inside the hot water tank. As a result, the radon component of the hot water tank is prevented from decreasing.

  In the water supply apparatus according to the fourth invention of the present invention, in addition to the third invention, the cold water supply means supplies cold water from a position biased toward the bottom surface of the cold water tank, and the hot water supply means is provided on the upper surface of the hot water tank. Supply hot water from an uneven position.

  With this configuration, cooler cold water is supplied from the cold water supply means, and hotter hot water is supplied from the hot water supply means.

  In the water supply machine according to the fifth aspect of the present invention, in addition to any one of the first to fourth aspects, the hot water tank is hermetically sealed except for the pipeline and the hot water supply means.

  With this configuration, the hot water tank is always filled with hot water, and radon components are not reduced by the generation of steam.

  In the water supply apparatus according to the sixth aspect of the present invention, in addition to any of the first to fifth aspects of the invention, the heating means maintains the hot water stored in the hot water tank between the first temperature and the second temperature. First temperature <second temperature <water boiling temperature.

  In the water supply device according to the seventh aspect of the present invention, in addition to the sixth aspect, the first temperature is 79 degrees to 83 degrees, and the second temperature is 89 degrees to 93 degrees.

  With these configurations, since the hot water does not boil inside the hot water tank, the radon component is prevented from being reduced by boiling. Furthermore, since the hot water tank is always full, the radon component of the hot water inside the hot water tank is prevented from decreasing.

  In the water supply apparatus according to the eighth aspect of the present invention, in addition to any one of the second to seventh aspects, at least one of the water tank and the hot water tank includes a case that can store the radium ore body.

  With this configuration, even general water can be modified into radon water, and the radon-containing concentration of the modified radon water is hardly reduced.

  In the water supply apparatus according to the ninth aspect of the present invention, in addition to the eighth aspect, the case has a through hole that allows the water stored in at least one of the cold water tank and the hot water tank to contact the radium ore body. Have.

  With this configuration, the radium ore body can efficiently emit radium radiation to water.

  In the water supply machine according to the tenth aspect of the present invention, in addition to any one of the second to seventh aspects, only the cold water tank includes a case that can store the radium ore body.

  With this configuration, an appropriate balance can be achieved between the cost required for the ore body and the maintenance (giving) of the radon-containing concentration of potable water supplied from the cold water tank and the hot water tank.

  In the water supply apparatus according to the eleventh aspect of the present invention, in addition to any of the first to tenth aspects, the radium ore body is one or more ceramic balls containing less than 50 wt% radium ore. .

  This configuration facilitates handling of the radium ore body.

  In the water supply apparatus according to the twelfth aspect of the present invention, in addition to any one of the first to eleventh aspects of the invention, air for supplying air for extruding at least one of cold water and hot water to at least one of the cold water tank and the hot water tank A tube, and the air tube is in thermal contact with the heating means.

  By this structure, the air which water contacts inside a water supply machine is sterilized reliably, and the safety | security and the hygiene aspect of the drinking water supplied from a water supply machine increase dramatically.

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

  In addition, the radon water in this specification means the water or hot water containing the radon component which is a radiation component by a radium ore body. The drinking radon water means a radon water that can be drunk, and may be used not only for drinking but also for cooking and cooking.

  The general water refers to water that does not contain an effective concentration of radon component, such as tap water, mineral water, natural water, and alkali ion water.

(Embodiment 1)
First, the general outline of the water supply apparatus will be described with reference to FIGS. 1 and 2.

(Overview)
(Summary 1: Water supply machine in which a water container for storing radon water is installed in advance)
FIG. 1 is a structural diagram of a water feeder according to Embodiment 1 of the present invention.

  A water supply 1 shown in FIG. 1 has the same configuration as the water supply 1 shown in FIG. 2 to be described later, a radium ore body is not installed in the cold water tank 5 and the hot water tank 6, and a water container 2 contains radon water. That is, in the water supply device 1 shown in FIG. 1, radon water containing a radon component is stored in the water container 2 in advance, and the water supply device 1 supplies radon water stored in the water container 2.

  Here, the radon component has a physically determined half-life of 3.8 days. Even if the water container 2 contains radon water, the water stored in the water container 2 may be stored in the water feeder 1 for several days to several weeks depending on the frequency of use by the user. Thus, when radon water is stored in the water feeder 1 for a long period of time, radon components are reduced according to a half-life of 3.8 days. Nevertheless, it is impossible to resist the physical half-life. However, in the conventional water supply machine, when hot water is generated inside the hot water tank, steam is generated, and the radon component is reduced according to the steam.

  1 has a water container 2 for containing water, a transport means 3 for transporting water in the water container 2 by natural flow, a cooling means for cooling the water transported by the transport means 3, From the cold water tank 5 for temporarily storing the obtained cold water, the hot water tank 6 for temporarily storing the hot water obtained by having the heating means for heating the cold water supplied by the pressure difference from the cold water tank 5, and the cold water tank 5 And a conduit 31 for supplying cold water to the hot water tank 6. The water stored in the water container 2 is not ordinary water but radon water. This radon water is taken from, for example, a natural radon spa, or radon water that has been radonized in a factory.

  The pipe line 31 connects the cold water tank 5 and the hot water tank 6, and the hot water tank 6 is positioned below the cold water tank 5 so that a pressure difference is generated between the cold water tank 5 and the hot water tank 6. It has become. The pipe line 31 supplies cold water from the cold water tank 5 to the hot water tank 6 using this pressure difference.

  Cold water supply means 14 is connected to the cold water tank 5, and cold water is supplied from the cold water tank 5 when the cold water cock provided in the cold water supply means 14 is opened. The cold water tank 5 is provided with a cooling means for cooling water.

  Similarly, hot water supply means 15 is connected to the hot water tank 6, and hot water is supplied from the hot water tank 6 when the hot water cock provided in the hot water supply means 15 is opened. The hot water tank 6 is provided with heating means for heating water.

  When cold water is supplied from the cold water supply means 14, the water inside the cold water tank 5 decreases, so that the water is conveyed from the water container 2 to the cold water tank 5 so as to compensate for the decrease. Similarly, when hot water is supplied from the hot water supply means 15, the water inside the hot water tank 6 decreases, so that the cold water is conveyed from the cold water tank 5 to the hot water tank 6 so as to compensate for the decrease.

  That is, the hot water tank 6 is always full.

  By being in a full water state, an air layer is not generated in the hot water tank 6 and steam from the hot water is not generated. This is because the hot water tank 6 is fully filled up to the ounce supply means 15. Further, the hot water tank 6 is completely sealed except for the connection portion between the hot water supply means 15 and the pipe line 31, and no air layer is formed around the hot water of the hot water tank 6 as long as it is full. . As a result, no hot water vapor is generated in the hot water tank 6.

  In this way, the hot water tank 6 is located below the cold water tank 5, and the cold water tank 5 supplies water to the hot water tank 6 due to the pressure difference between the cold water tank 5 and the hot water tank 6 (the pressure difference is always generated). By doing so, steam generation in the hot water tank 6 is suppressed, and radon component reduction is prevented. Of course, in the water supply 1 of FIG. 1, since radon water is supplied from the water supply 1 as it is, the reduction which exceeds a physical half-life cannot be prevented. In the first place, it is impossible to resist the physical half-life. Therefore, if it is possible to prevent the radon component from decreasing at a speed faster than the half-life, it is considered sufficient for practical drinking.

  Further, as will be described later, the heating means for heating the hot water tank 6 maintains the temperature of the hot water between the first temperature and the second temperature (the second temperature is less than the boiling temperature of water), so that the hot water tank 6 The internal hot water is not boiled and the radon component is further prevented from decreasing.

  Next, the case where the water container 2 contains general water instead of radon water, and at least one of the cold water tank 5 and the hot water tank 6 is a water feeder provided with a radium ore body will be described.

  In addition, the various structures and structures demonstrated below are applicable to the water feeder 1 shown by FIG.

(Summary 2: Water supply machine in which a water container for storing general water is installed)
FIG. 2 is a structural diagram of the water feeder according to Embodiment 1 of the present invention.

  In the water feeder 1 of FIG. 2, the water container 2 contains general water.

  In addition, in the water feeder 1 shown by FIG. 2, the water container 2 may accommodate radon water instead of general water.

  If the water container 2 contains general water, the water supply device 1 is composed of radium ore provided in at least one of the cold water tank 5 and the hot water tank 6, and the cold water and hot water supplied by the water supply device 1 are radon. Contains ingredients. That is, the water feeder 1 can give radon components to general water to make radon water, and can prevent a decrease in radon components of hot water stored in the hot water tank 6.

  On the other hand, when the water container 2 contains radon water, the water supply device 1 maintains the radon component concentration of cold water and hot water by the radium ore body provided in at least one of the cold water tank 5 and the hot water tank 6. To do. In particular, it is possible to prevent a decrease in the radon component of hot water stored in the hot water tank 6.

  In addition, the water feeder 1 of Embodiment 1 has the structure which prevents that a radon component reduces by boiling or generation | occurrence | production of a vapor | steam in a warm water tank, and the water which the water container 2 accommodates is radon water in general. Whether it is water or whether the radium ore body is installed in the cold water tank 5 or the hot water tank 6 may be determined depending on the use mode.

  The water feeder 1 has a water container 2 for containing water, a transport means 3 for transporting the water in the water container 2 by natural flow, and a cooling means for cooling the water transported by the transport means 3, and the obtained cold water is temporarily stored. Cold water tank 5 to be stored, a hot water tank 6 for temporarily storing hot water obtained by having a heating means for heating the cold water supplied by the pressure difference from the cold water tank 5, and cold water from the cold water tank 5 to the hot water tank 6 A conduit 31 for supplying

  The pipe line 31 connects the cold water tank 5 and the hot water tank 6, and the hot water tank 6 is positioned below the cold water tank 5 so that a pressure difference is generated between the cold water tank 5 and the hot water tank 6. It has become. The pipe line 31 supplies cold water from the cold water tank 5 to the hot water tank 6 using this pressure difference.

  Further, at least one of the cold water tank 5 and the hot water tank 6 can store a radium ore body. In the water feeder 1 of FIG. 2, the cold water tank 5 and the hot water tank 6 include cases 12 and 13 that can store radium ore bodies.

  The water container 2 has a capacity of several tens of liters, and each of the cold water tank 5 and the hot water tank 6 has a capacity of several liters or more.

  The water accommodated in the water container 2 carries the water to the cold water tank 5 by natural flow caused by gravity. The cold water tank 5 is connected to the hot water tank 6 via a pipe 31 and supplies cold water to the hot water tank 6 by a pressure difference.

  Cold water supply means 14 is connected to the cold water tank 5, and cold water is supplied from the cold water tank 5 when the cold water cock provided in the cold water supply means 14 is opened. The cold water tank 5 is provided with a cooling means for cooling water.

  Similarly, hot water supply means 15 is connected to the hot water tank 6, and hot water is supplied from the hot water tank 6 when the hot water cock provided in the hot water supply means 15 is opened. The hot water tank 6 is provided with heating means for heating water.

  When cold water is supplied from the cold water supply means 14, the water inside the cold water tank 5 decreases, so that the water is conveyed from the water container 2 to the cold water tank 5 so as to compensate for the decrease. Similarly, when hot water is supplied from the hot water supply means 15, the water inside the hot water tank 6 decreases, so that the cold water is conveyed from the cold water tank 5 to the hot water tank 6 so as to compensate for the decrease.

  Thus, the water conveyed from the water tank 2 is stored in the storage means (the cold water tank 5 and the hot water tank 6) for a certain period of time before being supplied as cold water or hot water. The storage time is determined by the capacity of the cold water tank 5 and the hot water tank 6 and the amount used for drinking, but it is considered that water stays in the storage means for several days as long as it is used for drinking. This is because even if 2 liters / day of water is used for drinking, the capacity of the cold water tank 5 and the hot water tank 6 is several liters or more, so the storage period is calculated to be several days.

  Here, each of the case 12 provided in the cold water tank 5 and the case 13 provided in the hot water tank 6 can store a radium ore body. If each of these cases 12 and 13 contains a radium ore body, radon components are contained in water by the radium radiation emitted from the radium ore body.

  When the radon water containing radon component is already stored in the water container 2, it takes several days until the radon water stored in the water container 2 is supplied as potable water. Will have a time lag. In the water server and water supply device of the prior art, the radon content concentration of the drinking water supplied is remarkably reduced by the time lag of several days. However, since the water feeder 1 of Embodiment 1 is provided with a radium ore body in the storage means, radium radiation is contained in the drinking radon water from the water container 2 to the cold water supply means 14 (or the hot water supply means 15). Radiated. As a result, the drinking water supplied from the cold water supply means 14 or the hot water supply means 15 maintains a sufficient radon-containing concentration.

  Alternatively, when normal mineral water is stored in the water container 2, storage until the mineral water stored in the water container 2 is supplied from the cold water supply means 14 (or the hot water supply means 15). During the period, mineral water receives radium radiation. As described above, the storage period is not uniquely determined, but is considered to be several days, so that sufficient radon component is contained in the mineral water during this storage period. As a result, the drinking water supplied from the cold water supply means 14 and the hot water supply means 15 contains a radon component.

  As described above, when the water contained in the water container 2 is a drinking radon water containing a radon component, the water feeder 1 of the first embodiment can maintain the radon-containing concentration of the drinking water supplied, When the water stored in the water container 2 is mineral water, the water feeder 1 according to the first embodiment can supply drinking water containing a radon component.

  Here, when radon water was heated to become warm water, there was a problem that radon-containing components decreased. In particular, for cold water, if there is sufficient radiation of radium radiation, a sufficient radon-containing concentration can be ensured, but in the case of hot water, there is a problem that the radon-containing concentration cannot be ensured due to steam generation or the like.

  In the water supply machine shown in FIG. 2, the hot water tank 6 is located below the cold water tank 5. Cold water is supplied to the hot water tank 6 from the cold water tank 5 via the pipe line 31. A pressure difference caused by a difference in height between the cold water tank 5 and the hot water tank 6 supplies the cold water. Since this pressure difference is always generated, when the water in the hot water tank 6 decreases and an air layer is generated in the hot water tank 6, the cold water tank 5 always supplies the cold water to the hot water tank to fill this air layer (gap). 6 is supplied. For this reason, the hot water tank 6 is always full of water.

  Thus, since the warm water tank 6 is always filled with warm water, steam cannot be generated inside the warm water tank 6. Since steam is not generated, the hot water in the hot water tank 6 does not have to reduce its radon component.

  The water stored in the hot water tank 6 is water that has passed through the water container 2 and the cold water tank 5 and has already obtained a radon component by radium radiation in the water container 2 and the cold water tank 5. For this reason, the hot water in the hot water tank 6 has a longer time to receive the radium radiation than the cold water in the cold water tank 5, so that the radon component content is increased.

  For example, when the water container 2 contains radon water having a radon component in advance, the radon water that reaches the hot water tank 6 is once exposed to radium radiation in the cold water tank 5. Since the cold water once exposed to the radium radiation in the cold water tank 5 reaches the hot water tank 6, the radon content concentration of the water reaching the hot water tank 6 is sufficient. Furthermore, since the water stored in the hot water tank 6 is exposed to radium radiation inside the hot water tank 6, the radon-containing concentration further increases. As a result, the radon-containing concentration can be higher than the cold water stored in the cold water tank 5.

  Alternatively, when the water container 2 contains mineral water, the water transported from the water container 2 to the cold water tank 5 is exposed to radium radiation inside the cold water tank 5. The radium radiation causes the water in the cold water tank 5 to contain a radon component. The cold water containing the radon component is supplied to the hot water tank 6 by the pressure difference. In the hot water tank 6, radium radiation is exposed to the stored hot water, so that the radon-containing concentration of the stored hot water is further increased.

  Thus, the water supply device 1 is configured in the order of the water container 2, the cold water tank 5, and the hot water tank 6, so that the hot water in the hot water tank 6 is exposed to radium radiation more than the cold water in the cold water tank 5. There are many. For this reason, the hot water in the hot water tank 6 is easier to ensure a higher radon-containing concentration than the cold water in the cold water tank 5.

  Further, the hot water tank 6 is supplied with cold water from the cold water tank 5 due to a pressure difference with the cold water tank 5. Since the pressure difference always occurs due to the positional relationship between the cold water tank 5 and the hot water tank 6, when the hot water in the hot water tank 6 decreases (by supplying hot water from the hot water supply means 15), the cold water is immediately supplied from the cold water tank 5. Is supplied. For this reason, the inside of the hot water tank 6 is always full. For this reason, no steam is generated inside the hot water tank 6, and the radon-containing concentration of the hot water in the hot water tank 6 is difficult to decrease.

  As described above, the water feeder 1 shown in FIG. 2 (1) changes the mineral water stored in the water container 2 into cold water and hot water containing radon components, or (2) stored in the water container 2. While maintaining the radon-containing concentration of radon water, it is possible to achieve (3) a sufficient radon-containing concentration of hot water as well as cold water.

  The radium ore bodies of the cold water tank 5 and the hot water tank 6 may be stored, or the radium ore body may be stored only in the cold water tank 5. Since there is a difference in the contact time between water and radium ore body, there will be a difference in the degree of reforming water to radon water or maintaining radon-containing concentration. This is because the radon component is contained in the hot water.

  Further, the radium ore body may be put into the cold water tank 5 and the hot water tank 6 without being stored in the cases 12 and 13.

  Of course, as shown in FIG. 1, even in the case of a water supply machine in which no radium ore body is installed, the radon content concentration of radon water stored in the water container 2 is difficult to decrease, and especially the decrease in the hot water tank 6 is prevented. Is done.

  2 shows the water supply 1 having a structure in which an inverted water container 2 is attached to the upper part of the water supply 1 and water is supplied by natural flow. As shown in FIG. Even in the case of the water supply device 1 that is attached and has a structure for supplying water by suction, potable water containing a radon component can be supplied.

  FIG. 3 is a structural diagram of the water feeder according to Embodiment 1 of the present invention. Elements denoted by the same reference numerals as those in FIG. 2 have functions similar to those described in FIG.

  In the water supply device 1 shown in FIG. 3, a water container 2 is attached to the lower portion of the water supply device 1, and water is transported to the cold water tank 5 existing at the upper portion by a pump 30 having a suction function. The cold water tank 5 supplies cold water to the hot water tank 6 via the pipe line 31, and the hot water tank 6 heats the supplied cold water to generate hot water.

  3, the cold water tank 5 includes a case 12 that can store a radium ore body, and the hot water tank 6 also includes a case 13 that can store a radium ore body. Since each of the cases 12 and 13 stores radium ore bodies, these radium ore bodies emit radium radiation to the cold water stored in the cold water tank 5 and the hot water stored in the hot water tank 6. As in the case of the water feeder 1 in FIG. 2, the radon-containing concentration of the cold water supplied from the cold water tank 5 and the hot water supplied from the hot water tank 6 are maintained, or drinking water containing a radon component is used. It becomes.

  Thus, even if there is a difference in the transportation means from the water container 2, the supplied drinking water is supplied as drinking radon water having a sufficient radon-containing concentration.

  3 is also provided with a hot water tank 6 below the cold water tank 5, and the cold water tank 5 supplies cold water to the hot water tank 6 due to a pressure difference between the cold water tank 5 and the hot water tank 6. . Since the pressure difference always occurs, when the hot water is supplied from the hot water supply means 15 and the hot water in the hot water tank 6 decreases, the cold water tank 5 immediately supplies the cold water to the hot water tank 6. For this reason, the hot water tank 6 always maintains a full state unless the water in the cold water tank 5 runs out. For this reason, no steam is generated inside the hot water tank 6, and the radon-containing concentration of the hot water does not decrease.

  The hot water stored in the hot water tank 6 is also exposed to the radium radiation in the cold water tank 5, and has a larger amount of time to receive the radium radiation than the cold water stored in the cold water tank 5.

  From the above, the radon-containing concentration of the hot water supplied by the water supply device 1 shown in FIG. 3 is sufficiently maintained, like the water supply device 1 shown in FIG.

  Thus, if the configuration of the cold water tank 5 and the hot water tank 6 is a predetermined configuration, the object of the water feeder of the first embodiment can be achieved even if there is a difference in the water container 2 and other mechanisms.

  Furthermore, when water is transported from the water container 2 to the cold water tank 5 by the pump 30, even if steam is generated in the cold water tank 5 or the hot water tank 6, the reverse flow of the steam to the water container 2 is performed by the pump 30. Is prevented. When the steam flows back to the water container 2, the steam (including radon component) may be released to the outside air when the water container 2 is replaced. However, since the pump 30 has a valve that prevents the reverse flow of water from the water container 2 toward the cold water tank 5, this valve also prevents the reverse flow of steam. However, when the water container 2 is replaced, since fresh water (mineral water or radon water) is supplied to the cold water tank 5 or the hot water tank 6, there is almost no demerit due to such a reverse flow of steam.

  Thus, when the water feeder 1 includes the pump 30, it is possible to further prevent the radon component from being reduced due to the backflow of the steam (including the radon component).

  Next, the detail of each part is demonstrated.

(Water container)
Details of the water container 2 will be described.

  The water container 2 is formed of a material such as resin, vinyl, or metal, and has a predetermined shape and a predetermined capacity. The capacity may be determined as appropriate, but for use or delivery at home or office, a size of about 10 to 50 liters is appropriate for ease of collection. The predetermined shape may be determined as appropriate, but a rectangular shape, a cylindrical shape, or the like is appropriate from the viewpoint of ease of use and storage.

  Moreover, as FIG. 4 shows, the water container 20 may have the softness | flexibility which can deform | transform. FIG. 4 is a perspective view showing a modification of the water container in Embodiment 1 of the present invention. Since the water container 2 has a deformable flexibility, the water container 2 can contract as the water contained in the water container 2 is sucked and reduced. Since the water container 2 can be contracted in accordance with the reduction of the water to be stored, air does not enter the water container 2 in accordance with the suction from the pump 30, and the water in the water container 2 does not need to contact the air. As a result, the water in the water container 2 is sucked up only by the suction pressure of the pump 30.

  Of course, even in the case of use under natural flow as shown in FIG. 2, the water container 2 is flexible as shown in FIG. Even in this case, the water stored in the water container 2 does not come into contact with the air, so that the water is kept hygienic.

  Since the water container 2 has such flexibility, a flexible film (polypropylene film, polyethylene laminate film, etc.) is used as the material of the water container 2, and it is harmful to the human body (for example, elution of environmental hormones). Etc.) A material that does not exist is used.

  The water container 2 may be delivered to a home or office in a state where water is accommodated, and may be collected when the water runs out. In this way, the user can maintain the sanitation and safety of the water supplied by the water feeder 1 by not filling the water container with tap water or natural water.

  Further, when the water container 2 is connected to the pipe line, an antibacterial band is attached to the tip of the pipe line, and the antibacterial band moves when the tip of the pipe line is inserted into the mouth of the water container 2. By having such a structure, when the pipe line and the water container 2 are connected, the possibility that various germs are mixed into the water stored in the water container 2 is reduced.

(Transportation means)
The carrying means carries the water in the water container 2 to the cold water tank 5 by at least one of natural flow or suction.

  FIG. 2 shows a water feeder 1 using natural flow, and the transport means 3 transports water to the cold water tank 5 by natural flow from the water container 2.

  FIG. 3 shows a water supply device 1 using suction, and the water supply device 1 includes a pump 30 as an example of a transportation means.

  The pump 30 is an example of a suction unit. The pump 30 may be a compression pump or a rotary pump. In any case, it is sufficient that water from the water container 2 can be sucked by the suction pressure. In the water feeder 1 of FIG. 3, the water container 2 is connected to the cold water tank 5, so the pump 30 carries water from the water container 2 to the cold water tank 5.

  The pump 30 may be activated or stopped depending on the displacement of the water level of the cold water tank 5. For example, a water level detector 35 is provided inside the cold water tank 5, and a detection signal from the water level detector 35 is output to the pump 30. When the water level detector 35 is below the predetermined level, the pump 30 is activated to suck water from the water container 2. Water is supplied from the water container 2 to the cold water tank 5 by the operation of the pump 30, and the water level of the cold water tank 5 rises.

  The water level detector 35 (for example, a float) notifies the pump 30 when the water level in the cold water tank 5 becomes a predetermined level or higher, and the pump 30 that has received the notification stops suction. This is because the cold water overflows from the cold water tank 5 unless the pump 30 stops the suction. The water level detector 35 is electrically connected to the pump 30 to notify information about the water level as an electric signal. Of course, the water level detector 35 and the pump 30 may exchange electrical signals wirelessly.

(Cold water tank and hot water tank)
2 and 3, a pipe 31 is connected from the cold water tank 5 to the hot water tank 6. The water sucked from the water container 2 is stored in the cold water tank 5, and the water is transported from the cold water tank 5 to the hot water tank 6 through the pipeline 31.

  As shown in FIGS. 2 and 3, a hot water tank 6 is located below the cold water tank 5, and a pressure difference is generated between the cold water tank 5 and the hot water tank 6 due to a difference in height. . The cold water tank 5 supplies cold water to the hot water tank 6 using this pressure difference. Further, the water supply from the cold water tank 5 to the hot water tank 6 is performed only through the pipe line 31, and the hot water tank 6 is sealed against the outside air except for the connection part of the pipe line 31 and the hot water supply means 15. Has been.

  The cold water tank 5 has a cooling means for cooling the stored water, and cools the stored water.

  The cooling means includes an evaporation pipe 7, a condenser 8 connected to the evaporation pipe 7, and a compressor 9. The cooling air heat-exchanged by the compressor 9 and the condenser 8 is supplied to the evaporation pipe 7, and the cold water tank 5 is cooled by the latent heat when the cooling air evaporates. By cooling the cold water tank 5, the water stored inside is cooled and cold water is obtained. For this reason, the cold water tank 5 is preferably made of metal from the viewpoint of good thermal conductivity. In addition, other than metal, resin, vinyl, ceramics, etc. may be used.

  A sterilizing ultraviolet lamp 37 may be provided inside the cold water tank 5. The sterilizing ultraviolet lamp 37 may be constantly lit or may be lit only for a predetermined period. Moreover, you may provide the water level detector 35 used as the reference | standard of the action | operation of the pump 30, and a stop as above-mentioned.

  A pair of magnets 42 are attached to the outer periphery of the cold water tank 24 so as to face each other. The magnets 42 activate water molecules (clusters) by passing a magnetic field through the water, thereby preventing water corrosion. It is also possible to suppress the propagation of germs.

  The cold water tank 5 also includes a connection pipe 31 for supplying cold water to the hot water tank 6, which is formed from the bottom surface of the cold water tank 5 to the upper surface of the hot water tank 6. The cold water stored in the cold water tank 5 moves from the opening of the connection pipe 31 to the hot water tank 6 provided under the cold water tank 5 by the pressure generated from the pressure difference.

  Here, the evaporation pipe 7 is provided in the lower part of the cold water tank 5. By being provided in the lower part, the temperature of the water stored in the cold water tank 5 is lower as it is closer to the bottom surface, and the temperature is higher as it is closer to the upper part (near the opening of the connection pipe 31). In addition, the cold water supply means 14 extends from the bottom surface of the cold water tank 5.

  By having such a configuration, cooler water is supplied from the cold water supply means 14 in the cold water tank 5, and relatively warm water moves from the cold water tank 5 to the hot water tank 6. When the warm water moves to the hot water tank 6, the heating burden in the hot water tank 6 is reduced.

  In addition to the outer periphery and bottom surface, the top surface of the cold water tank 5 is also sealed, and the inside of the cold water tank 5 is not exposed to the outside air except for the internal passage of the air pipe that gives the air pressure for pushing out the water of the cold water tank 5. That is, the water stored in the cold water tank 5 does not come into contact with outside air other than the air supplied from the air pipe. Since the water passing from the water container 2 via the pipe line 32 is sucked only by the pressure from the pump 30, it does not come into contact with the outside air. In addition, water does not touch outside air other than the air supplied from the air pipe even inside the cold water tank 5. Thus, the cold water supplied from the cold water tank 5 is sanitary and safe.

  A water supply path connected to the cold water supply means 14 is connected to the cold water tank 5. The water supply channel is preferably connected to the bottom surface of the cold water tank 5, but may be connected to a side surface close to the bottom surface instead of the bottom surface. Cold water is sent out to the cold water supply means 14 from the water supply channel. When the water supply cock provided in the cold water supply means 14 is opened, cold water is supplied by the pressure from the cold water tank 5. The cold water supply means 14 may be structured to open and close like a faucet, or may be structured to open and close by moving the lid up and down.

  Next, the hot water tank will be described.

  As shown in FIGS. 2 and 3, the hot water tank 6 is connected to the lower side of the cold water tank 5 by a pipe 31 and water is supplied from the cold water tank 5 to the hot water tank 6.

  Similarly to the cold water tank 5, the hot water tank 6 is sealed with respect to the outside, and the hot water inside does not contact the outside air.

  A heating band 10 as an example of a heating unit is provided on the outer periphery of the hot water tank 6. The heating band 10 includes a heating wire that converts electricity into heat and generates heat to heat the hot water tank 6. For this reason, the heating band 10 is preferably attached to the outer periphery of the hot water tank 6. Moreover, it is suitable that the heating band 10 is attached in the lower part near the bottom face of the hot water tank 6. This is because water having a high temperature rises, and by attaching the heating band 10 to the lower part, it is possible to heat water that has not yet been heated sufficiently, and the efficiency is good. In addition, because the heating band 10 is positioned at the lower portion, convection inside the hot water tank 6 can be promoted, and hot water can be obtained efficiently. The hot water tank 6 may be formed of various materials such as resin, vinyl, earthenware, and metal, but for efficient heating by the heating band 10, it is formed of a metal having high thermal conductivity. preferable.

  Moreover, the hot water supply means 15 is connected to the hot water tank 6 through a water supply channel. Like the cold water supply means 14, the hot water supply means 15 may have a structure that opens and closes like a faucet, or a structure that opens and closes a lid up and down like a cock. Here, the water supply channel is connected to the upper surface (or the side surface close to the upper surface) of the hot water tank 6 so that hot water having a higher temperature is supplied from the hot water supply means 15 inside the hot water tank 6. preferable.

  That is, the cold water supply means 14 extends from a position biased toward the bottom surface of the cold water tank 5 to supply cold water (cooler water is supplied), and the hot water supply means 15 is biased toward the upper surface of the hot water tank 6. It is preferable to extend from the position and supply warm water (hot water is supplied).

  It is also preferable that a temperature sensor is provided in at least one of the hot water tank 6 and the heating band 10, and that the operation and stop of the heating band 10 are controlled upon receiving a notification from the temperature sensor.

(Sterilization of air through the air pipe)
The air pipe 45 that sends air to apply pressure to push out the water stored in the cold water tank 5 or the hot water tank 6 may be heated by the heat of the heating band 10 so that the air passing through the air pipe 45 may be sterilized.

  As shown in FIG. 3, the air pipe 45 sends air into the cold water tank 5 after being in thermal contact with the heating band 10. 3 supplies water from the cold water tank 5 to the hot water tank 6 through the pipe line 31, the air pipe 45 supplies air only to the cold water tank 5.

  The air tube 45 is in thermal contact with the heating band 10. For example, as shown in FIG. 3, the air pipe 45 passes through the inside of the heating band 10. The heating band 10 is filled with a material considered to have a bactericidal effect while maintaining the temperature of stainless steel wire, stone, copper wire, silver wire or the like. By passing the air pipe 45 through the inside of the heating band 10 filled, a considerable temperature is given to the air pipe 45 and the air passing through the air pipe 45 is sterilized. In addition, these materials such as stone are excellent in heat retention, and reduce the amount of electric power required for heating by the heating band 10. Of course, the amount of heat applied to the air pipe 45 in thermal contact with the heating band 10 tends to increase due to the filling of these materials. That is, in addition to power consumption reduction, the sterilization ability can be improved.

  In the entire air pipe 45, a portion passing through the inside of the heating band 10 receives heat from the heating band 10, so that the inside becomes a considerably high temperature. It is considered that general bacteria start to die at about 80 ° C. or higher, so most of the bacteria that exist in the outside air and are concerned about the influence on drinking water are considered to be killed by heating from the heating band 10. .

  The heating band 10 for heating the hot water tank 6 has a temperature higher than that of the hot water tank 6. For example, when the hot water tank 6 is about 90 ° C., the heating band 10 can be about 130 ° C. That is, the region surrounded by the hot water tank 6 and the heating band 10 has a temperature of about 80 ° C. to 130 ° C. (Of course, this changes depending on the temperature control setting of the heating band 10). For this reason, it is considered that most of the germs are killed when the air tube 45 is in thermal contact with the heating band 10.

  Even when the heating band 10 stops operating, the heat from the hot water tank 6 is conducted to the air pipe 45, so that the air inside the air pipe 45 is sterilized by the heat from the hot water tank 6. Is done.

  The air pipe 45 may meander in the heating band 10. Since the air pipe 45 meanders in the heating band 10, there is an advantage that the contact area between the air pipe 45 and the heating band 10 is increased and the sterilization efficiency is improved. Of course, it contributes also to size reduction of the water feeder 1 whole.

  In this way, the air pipe 45 receives heat by passing through the inside of the heating band 10 or in thermal contact with the outside, and the air passing through the air pipe 45 is sterilized by the received heat.

  When the air pipe 45 sends air into the cold water tank 5, pressure is applied to the cold water tank 5, and when the cold water supply means 14 is opened, the cold water stored in the cold water tank 5 is supplied. Furthermore, when the air pipe 45 sends air into the cold water tank 5, pressure is applied to the cold water tank 5, and cold water is supplied from the cold water tank 5 to the hot water tank 6.

  The heating band 10 for sterilizing the air passing through the air pipe 45 is for heating water stored in the hot water tank 6 in the first place, and is not an element newly provided for sterilization. For this reason, the water feeder 1 can also suppress an increase in size while minimizing an extra cost and a manufacturing process.

  It is also preferable that the air tube 45 further includes a sterilization filter 36.

  The sterilization filter 36 is formed by polymerizing a nonwoven fabric or a fine cloth, or is formed by a metal plate having pores. In particular, it is also suitable that antibacterial agents and bactericides are applied and chemicals in the air are sterilized chemically.

  It is preferable that the sterilization filter 36 is in the front stage of the heating band 10 in the air pipe 45 with reference to the cold water tank 5 and the hot water tank 6. The heating band 10 sterilizes various germs in the air passing through the air pipe 45 by heat. At this time, if the sterilization filter 36 is provided in the front stage of the heating band 10, the amount of germs in the air entering the air tube 45 is first reduced by the sterilization filter 36, and the reduced germs are the heat of the heating band 10. Sterilized by. In the heating band 10, it is only necessary to heat sterilize the germs that have been reduced by the sterilization filter 36, so that the amount of germs to be heat sterilized is smaller than when there is no sterilization filter 36. For this reason, the burden of heat sterilization in the heating band 10 is reduced, and the heating band 10 can be sterilized reliably. In particular, the presence of the sterilization filter 36 in the front stage of the heating band 10 sterilizes the air passing through the air pipe 45 in the order of reduction of germs and heat sterilization of the reduced germs, so that the sterilization reliability is improved. improves.

  Of course, a structure in which the sterilization filter 36 is provided after the heating band 10 may be employed. In this case, the heating band 10 heat sterilizes almost all the germs, and the germs that have escaped the heat sterilization are sterilized by the sterilization filter 36.

  In any case, the sterilization of the air passing through the air pipe 45 is further ensured by combining the sterilization filter 36 with the heating band 10.

  It is also preferable that the sterilization filter 36 can be replaced by a user.

(Radium ore body and case)
Next, a radium ore body and a case for housing it will be described.

  FIG. 5 is a perspective view showing a case for storing the radium ore body. The cases 12 and 13 are cases having similar structures and functions, respectively. The case 12 is installed in the cold water tank 5, and the case 13 is installed in the hot water tank 6.

  The radium ore body 50 is an ore or a processed product of ore that can emit radium radiation. The radium ore itself, which is the raw material of the radium ore body 50, is collected from the natural world. However, the radium ore body itself collected from the natural world may be used as the radium ore body 50 or may be used after being processed. . The radium ore body 50 may have any shape and form as long as it can emit radium radiation.

  The radium ore body 50 is also preferably a ceramic ball containing less than 50% by weight of radium ore because of easy handling. Ceramic balls are formed by mixing powdered radium ore with ceramics and clays and firing them. Ceramics and clays are also powders, and are molded into a predetermined shape when the powdered radium ore and the powdered ceramics and clays are mixed and fired.

  The name of the ball is not limited to a sphere, and may include a corner, an ellipse, or a shape having a shape close to a cube or a rectangular parallelepiped. The ceramic ball contains less than 50% by weight of the radium ore body, so that it can radiate radium radiation and has a merit that handling is facilitated by mixing ceramic and clay powders.

  The ceramic balls are accommodated in the cases 12 to 13 as the radium ore body 50.

  Here, the ceramic balls may be large and single, but are preferably small and plural in order to increase the radiation efficiency of the radium radiation. This is because even if the total weight is the same, the total surface area of the small ceramic balls is larger than that of the large and simple ceramic balls. Since the total surface area is large, the area for emitting radium radiation is increased, and the radiation efficiency of radium radiation is increased.

  Moreover, it is preferable that the ceramic ball has a larger diameter than the through hole 51 provided in the cases 12 to 13. This is to prevent the cases 12 to 13 from spilling. It is also effective in increasing the surface area that the ceramic balls have fine holes on the surface.

  In addition, the radium ore body 50 can be reused by being taken out of the cases 12 to 13 or being washed from the cases 12 to 13 and washed. Become.

  The ceramic balls are housed in the cases 12 to 13 and attached to at least one of the cold water tank 5 and the hot water tank 6 to radiate radium radiation toward the inside of each tank. By the radium radiation of the radium ore body 50 including this ceramic ball, the radon-containing concentration of drinking radon water originally having a radon-containing concentration is maintained at a predetermined concentration. At this time, since the radium ore body 50 can emit radium radiation semipermanently, the radon-containing concentration of water contained in each tank is maintained semipermanently (of course, usually several days to several months). During this period, the radon-containing concentration is sufficiently maintained since the contained water is used up.

  When radon water containing radon components is already stored in the water container 2, even if the radon water is stored in the cold water tank 5 and the hot water tank 6 for several days, the radon-containing concentration is maintained during this storage period. Maintained. On the other hand, when mineral water is stored in the water tank 2, the mineral water is stored in the cold water tank 5 and the hot water tank 6 for several days, so that the mineral water is absorbed by the radium radiation from the radium ore body 50. Contains radon component. That is, when a user drinks, the drinking water obtained from the water feeder 1 is radon water.

  In FIG. 5, the radium ore body 50 is stored in the cases 12 to 13 and then installed in the cold water tank 5 or the like. However, the cases 12 to 13 are not used and the radium ore body 50 is put into the cold water tank 5 or the like as it is. May be.

  The cases 12 to 13 are provided in at least one of the cold water tank 5 and the hot water tank 6. These tanks are installed inside or thrown in.

  It is also preferable that the cases 12 to 13 have a through hole 51 in a part of the case in order to efficiently radiate radium radiation from the radium ore body 50 accommodated therein to water. By having the through-hole 51, water and the radium ore body 50 can come into direct contact with the cold water tank 5 or the like, so that there is a merit that radium radiation easily affects water. Alternatively, since the through holes 51 are provided, the radium ore body 50 can be washed together with the cases 12 to 13 after the cases 12 to 13 are collected.

  Actually, the radium ore body 50 emits radium radiation to water via air to promote the radon content of water, so that the water and the radium ore body 50 may not be in direct contact with each other.

  The cases 12 to 13 may be attached to at least one lid of the cold water tank 5 and the hot water tank 6. This is because these tanks can be easily installed and removed from the tank.

  In addition, the cases 12 to 13 can be detached from the temporary tank 4 and the cold water tank 5, so that the maintenance of the water supply device 1 is performed (the water supply device is usually rented, and the rental period is updated, etc.) The cases 12 to 13 and the radium ore body 50 are cleaned. Thus, since the radium ore body 50 is reused by washing | cleaning, the selling price and rental price of the water feeder 1 provided with the radium ore body 50 are reduced.

  As described above, the water feeder in Embodiment 1 can provide drinking water to the user while maintaining the radon-containing concentration of radon water stored in the water container 2. Or the water supply machine in Embodiment 1 can provide a user with drinking water as radon water by making the mineral water accommodated in the water container 2 contain a radon component.

  In addition, the hot water stored in the hot water tank 6 is easily exposed to radium radiation, and the hot water tank 6 is always full so that steam is not easily generated inside the hot water tank 6. 1 can supply hot water in which the radon-containing concentration is difficult to decrease.

  The water feeder may have a configuration other than the configurations shown in FIGS. 2 and 3.

(Embodiment 2)
Next, a second embodiment will be described.

  FIG. 6 is a structural diagram of a water supply machine according to Embodiment 2 of the present invention. The water feeder of Embodiment 2 has a configuration in which water is supplied from the cold water tank 5 to the hot water tank 6 via the pipe line 31 as in FIG. That is, the water container 2 is installed at the bottom of the water feeder 1, and the pump 30 sucks the water in the water container 2 into the cold water tank 5. A hot water tank 6 is installed under the cold water tank 5, and water in the cold water tank 5 is supplied from the cold water tank 5 to the hot water tank 6 through a pipe line 31.

  Cold water supply means 14 for supplying cold water is connected from the cold water tank 5, and hot water supply means 15 for supplying hot water is connected from the hot water tank 6. The cold water supply means 14 and the hot water supply means 15 are each provided with a faucet and a water supply cock.

  When hot water is discharged from the hot water supply means 15, the hot water in the hot water tank 6 decreases, so that water is immediately supplied from the cold water tank 5 to the hot water tank 6 due to the pressure difference between the cold water tank 5 and the hot water tank 6. .

  On the other hand, when water moves from the cold water tank 5 to the hot water tank 6 or when cold water is discharged from the cold water supply means 14, the water level of the cold water tank 5 decreases. The cold water tank 5 is provided with a water level detector 35, and the water level detector 35 detects a drop in the water level. By the detection by the water level detector 3, the pump 30 is operated to suck water from the water container 2 into the cold water tank 5. Thus, as long as there is a remaining amount of the water container 2, water corresponding to the capacity of the cold water tank 5 and the hot water tank 6 is always supplied to the hot water tank 6 and the cold water tank 5.

  Here, each of the cold water tank 5 and the hot water tank 6 has a capacity of about several liters to 10 liters.

  Although depending on the use situation, it is considered that about 1 to 2 liters of drinking water is used in a day at home or office. Since each of the cold water tank 5 and the hot water tank 6 has a capacity of about several liters to 10 liters, drinking water supplied through the cold water supply means 14 and the hot water supply means 15 is several in the cold water tank 5 and the hot water tank 6. The water was stored for about a day.

  The radium radiation emitted from the radium ore body can contain a radon component in mineral water within a period of several days. For this reason, since the radium ore body is installed in the cold water tank 5 and the hot water tank 6, the mineral water accommodated in the water container 2 is supplied as radon water.

  Here, in the water feeder 1 shown in FIG. 6, since water is supplied from the cold water tank 5 to the hot water tank 6, the water stored in the hot water tank 6 always passes through the cold water tank 5. The cold water tank 5 has a larger capacity than the hot water tank 6 because it supplies water to the hot water tank 6 and also supplies cold water from the cold water supply means 14.

  For this reason, the radium ore body may be installed only in the cold water tank 5. The cold water tank 5 is larger than the hot water tank 6 and the drinking water supplied from each of the cold water supply means 14 and the hot water supply means 15 is water that has always been stored in the cold water tank 5. For this reason, even if the radium ore body is installed only in the cold water tank 5, drinking water comes to contain a radon component by the influence of the radium ore body.

  The radium ore body is often expensive, and the hot water tank 6 may not have a communication path to the outside other than the pipe line 31 (for example, it is integrally formed and the lid does not open). An ore body is provided. In this case, there exists a merit which contributes to the cost reduction of the water feeder 1. FIG. Even when the radium ore body is installed only in the cold water tank 5, as described above, since all the drinking water supplied has been stored in the cold water tank 5 for about several days, it is installed in the cold water tank 5. The radium ore body contains a radon component with high certainty. This can be realized in combination with the configuration in which the water in the water container 2 is first stored in the cold water tank 5 and then supplied from the cold water tank 5 to the hot water tank 6.

  Of course, a radium ore body may be installed in the hot water tank 6. By installing radium ore bodies in both the cold water tank 5 and the hot water tank 6, there is an advantage that the radon-containing concentrations of the cold water and the hot water are ensured.

  Next, the structure which further reduces the reduction | decrease of radon content concentration of the warm water stored in the warm water tank 6 is demonstrated.

  The hot water tank 6 has a heating means. The heating means includes a heating band 10 and heats the hot water tank 6 to make the stored water warm water.

  At this time, the heating means can control the temperature of the hot water stored in the hot water tank 6 by controlling the heating temperature.

  For example, the heating means maintains the hot water stored in the hot water tank 6 between the first temperature and the second temperature that satisfy the relationship of first temperature <second temperature <water boiling temperature. Since the second temperature is lower than the boiling temperature of water, the hot water stored in the hot water tank 6 does not boil. If it does not boil, steam is not generated from the hot water, and the radon-containing component of the hot water is not reduced. The radon component of hot water is largely reduced by the generation of steam from hot water. The heating means controls the warm water tank 6 to be heated to a temperature below the boiling temperature, so that boiling of warm water does not occur inside the warm water tank 6.

  The first temperature is preferably from 79 degrees to 83 degrees. This is because the temperature of 79 degrees or more and 83 degrees or less makes the warm water stored in the warm water tank 6 an appropriate temperature for brewing tea or coffee. The second temperature is preferably 89 degrees or more and 93 degrees or less. When the temperature is 89 degrees or more and 93 degrees or less, the hot water stored in the hot water tank 6 is at a temperature suitable for brewing tea or coffee, and at the same time, it does not boil, reducing the radon component of the hot water. Can be prevented. In addition, the numerical value of 1st temperature and 2nd temperature is an example, Comprising: Naturally, other than this may be sufficient. When the boiling temperature differs depending on the state of the hot water tank 6, the numerical values of the first temperature and the second temperature may be different values. For example, when the hot water tank 6 is in a depressurized state, the boiling temperature is lowered, so the first temperature and the second temperature may be selected in accordance with the low boiling temperature.

  In short, the heating means may maintain the water in the hot water tank 6 between the first temperature and the second temperature in the relationship of first temperature <second temperature <water boiling temperature.

  FIG. 7 is a graph showing a heating curve by the heating means in Embodiment 2 of the present invention.

  The heating means maintains the hot water in the hot water tank 6 between the first temperature and the second temperature in the relationship of first temperature <second temperature <water boiling temperature.

  The heating means includes a control unit (for example, may be controlled by a microcomputer) and controls heating to the hot water tank 6. A microcomputer storing a simple computer program may be used.

  Moreover, since it should just be controlled so that warm water does not boil, the temperature difference of 1st temperature and 2nd temperature should just be defined arbitrarily. Alternatively, a mechanism controlled by the third temperature may be added depending on the situation.

  As described above, the water supply apparatus according to the second embodiment controls the heating conditions of the hot water tank 6 so that the hot water stored in the hot water tank 6 does not boil, and the hot water radon stored in the hot water tank 6 is used. The content concentration can be prevented from being reduced.

  In the water feeders in the first and second embodiments, the sterilization filter, thermal sterilization, sterilization ultraviolet lamp, filter for water purification, disinfectant, purification agent, antibacterial agent, ozone generator, etc. are provided in the temporary tank 4, the cold water tank. 5. It is also possible to ensure the sanitary aspect of drinking water by installing it in the hot water tank 6 and the water supply system.
