  A water storage tank 10 according to an embodiment of the present invention shown in FIG. 1 includes a tank main body 12, and the tank main body 12 is arranged in a suitable place such as a place with high strength in a house 14, that is, a place with many pillars. . For example, on the bathroom 16, on the toilet, or on the attic 20. In addition, a rooftop can be installed in a house with a rooftop. And the water tank 10 is connected to a water supply system pipe line in the place. The water supply line includes a water supply pipe 24 extending from the water pipe 22 to the house, and the water storage tank 10 is used to connect each water intake tap to the water supply pipe 24 and supply tap water to the house. That is, in this embodiment, the water tank 10 functions as a water supply header and also functions as an emergency water tank.

  As shown in FIG. 2, the tank body 12 is a pipe made of synthetic resin such as hard vinyl chloride or polyethylene, and both openings thereof are closed by an introduction surface 26 and a lead-out surface 28. The tank body 12 has an internal capacity of, for example, 45 liters, a size of 2.7 m for a φ150 pipe, and a length of 1.5 m for a φ200 pipe. 45 liters corresponds to 3 days of drinking water usage for a family of 5 people.

  The introduction surface 26 is provided with an introduction port 30, and the water supply pipe 24 is connected to the introduction port 30. A plurality of water supply ports 32 a, 32 b, 32 c, 32 d, and 32 e are provided on the lead-out surface 28, and water distribution pipes 34 a, 34 b, 34 c, 34 d, and 34 e are connected to the respective water supply ports 32. The water distribution pipe 34 is, for example, a flexible synthetic resin pipe or the like, and a normal water intake tap in the house is connected to the water distribution pipe 34. For example, as shown in FIG. 1 and FIG. 2, the water distribution pipe 34a is a water tap of the washroom 36, the water distribution pipe 34b is a tank of the toilet 18, the water distribution pipe 34c is a water tap of the kitchen 38, and the water distribution pipe 34d is a hot water supply. The water distribution pipe 34 e is connected to the faucet 16 a of the bathroom 16. The water distribution pipe 34 e is connected to the lowermost water supply port 32 e of the lead-out surface 28 and is connected to the water tap 16 a of the bathroom 16 below the water storage tank 10. The water tap 16a of the bathroom 16 is normally used as a water intake tap during normal times, but is used as an emergency water intake tap during an emergency.

  An intake hole, an intake / exhaust hole 40, and the like are provided at the top of the side surface of the tank body 12, and an intake / exhaust valve 42 is attached to the intake / exhaust hole 40.

  Usually, tap water is supplied from the water pipe 22 through the water supply pipe 24 to the tank body 12 and stored in the tank body 12. When the normal water tap is used, the tap water stored in the tank body 12 is supplied to the normal water tap through the distribution pipe 34, and new tap water is accordingly supplied from the water supply pipe 24 to the water tank. 10 is supplied. That is, every time domestic water is used, the tap water stored in the tank body 12 is replaced with new tap water supplied from the water supply pipe 24. For this reason, the tap water in the tank body 12 circulates and is always kept hygienic.

  In case of emergency, when tap water 16a of the bathroom 16 is used when tap water pressure is not acting on the tap water, the tap water in the tank body 12 naturally flows down through the water distribution pipe 34e and is below the tank body 12. It flows out from the water tap 16a of the bathroom 16. At this time, even if the tap water flows out of the tank body 12, the air is sucked into the tank body 12 from the intake / exhaust valve 42, and accordingly, the pressure inside the tank body 12 is maintained at atmospheric pressure. The tap water continues to flow down naturally.

Thus, since the flow corresponding to each water supply port 32 can be made to the tap water in the tank main body 12 by providing the water supply port 32 in the tank main body 12, the part where tap water stagnates in the tank main body 12 is In addition, the tap water in the tank body 12 is agitated in a wide range, and all the tap water in the tank body 12 is hygienic. In addition, if a normal water tap is connected to each water supply port 32, tap water in the tank body 12 is used as domestic water for home use and is therefore almost always taken out from each water supply port 32. Along with this, new tap water is supplied from the water supply pipe 24 to the tank body 12, so that the tap water in the tank body 12 is efficiently replaced. Therefore, even if no special maintenance such as cleaning of the tank body 12 is performed, the tap water in the tank body 12 circulates and is always kept clean, and clean water can be obtained even in an emergency.

  And if the tap 16a of the bathroom 16 of a normal water tap is used also as an emergency water tap, the tap water around the water supply port 32e in the water tank 10, the tap water in the distribution pipe 34e, etc. are usually used as domestic water. Therefore, such tap water is kept clean with almost no stagnation.

  Further, when a pipe made of synthetic resin such as hard vinyl chloride or polyethylene is used for the tank body 12, the tank body 12 is excellent in mechanical properties, particularly flexibility, so that even if an earthquake occurs, the tank body 12 may be cracked. It is difficult to enter and the tap water of the tank body 12 is secured. In particular, the bathroom 16 has many pillars in the house 14 and the distance between the pillars is narrow and strong, and is close to the faucet 16a of the bathroom 16 as an emergency intake tap. If it arrange | positions above, the tank main body 12 and the water pipe 34 will be hard to be damaged also at the time of an earthquake. And since the tap water in the tank main body 12 naturally flows down from the tank main body 12 above the bathroom 16 to the faucet 16a of the bathroom 16 below, the tank main body 12 even if the water supply pressure does not act in an emergency. The tap water is obtained from the water tap 16 a of the bathroom 16.

  Since the pipe made of synthetic resin such as hard vinyl chloride or polyethylene has high versatility, the water storage tank 10 can be provided at low cost. And since the types of pipe diameters are also abundant, if the pipe diameter is selected and the length of the pipe is selected or adjusted, the size of the tank body 12 can be made to correspond to the arrangement space of the tank body 12, There are few restrictions on the installation location. The tank body 12 may also be arranged in a conventional water supply system pipeline, and can be easily installed not only in a newly built house but also in renovation.

  Although the tank body 12 is provided with an intake hole or intake / exhaust hole 40 and the intake / exhaust hole 42 is attached to the intake / exhaust hole 40, the intake / exhaust hole 40 and intake / exhaust valve 42 need not be provided. In this case, if a water intake tap other than the water supply tap 16a of the bathroom 16 as an emergency water intake is opened, the water intake tap serves as an intake / exhaust hole.

  Moreover, the tank main body 12 can also be inclined and arrange | positioned. As shown in FIGS. 3A and 3B, the tank body 12 is inclined at an angle θ so that the introduction surface 26 of the tank body 12 is located above the lead-out surface 28 of the tank body 12. The water supply port 32e connected to the water tap 16a (FIG. 1) of the bathroom 16 is the lowermost part of the tank body 12, and the intake / exhaust hole 40 to which the intake / exhaust valve 42 is attached is the uppermost part of the tank body 12. As a result, the bottom of the tank body 12 is tilted, the tap water in the tank body 12 gathers at the bottom of the tank body 12 and is supplied from the water supply port 32e to the water tap 16a of the bathroom 16, and the air is sucked from the intake / exhaust valve 42. Therefore, all the tap water in the tank body 12 can be taken out.

As another method for inclining the bottom of the tank body, a tank body 43 shown in FIG. 4 can be used. The tank main body 43 is substantially the same as the tank main body 12 shown in FIG. 2, but the bottom of the tank main body 43 shown in FIG. 4 is inclined. That is, the bottom of the tank body 12 shown in FIG. 2 is perpendicular to the introduction surface 26 and the lead-out surface 28, but the bottom of the tank body 43 shown in FIG. 5 is at an angle (90 + θ) degrees with respect to the introduction surface 26. The angle (90−θ) degrees with respect to the derivation surface 28. For this reason, if this tank main body 43 is arrange | positioned in a horizontal surface and the introductory surface 26 and the derivation | leading-out surface 28 are made into a right angle with respect to a horizontal surface, the bottom part of the tank main body 43 will incline with respect to a horizontal surface.

  Further, as shown in FIG. 1, the tank body 12 is disposed on the bathroom 16, but the tank body 12 may be disposed below the living space such as the floor 44. As shown in FIG. 5, a water intake 48 is provided on the side of the tank body 12, and a lid 50 is attached to the water intake 48. Then, the lid 50 is removed in an emergency, and the tap water in the tank body 12 is directly pumped from the water intake 48 by a manual pump or an electric pump. In this case, an emergency water intake tap need not be provided. Further, if an emergency water intake tap is directly attached to the lowermost portion of the outlet surface 28, tap water can be supplied from this emergency intake tap.

  In addition to this, when the tank body 12 is disposed in the underground 46 or the like, the tap water in the tank body 12 is not drawn from the water intake 48 shown in FIG. 5 but from the emergency water tap such as the water tap 16a (FIG. 1) of the bathroom 16. Can also be taken out. As shown in FIG. 6, the pump 49 a is attached to the tank body 12. The pump 49a is connected to a storage battery 49b, and the storage battery 49b is connected to a household power supply 49c. The storage battery 49b is normally charged from a household power source 49c or the like. When the pump 49a is operated by the storage battery 49b in an emergency, the tap water in the tank body 12 is supplied to the emergency intake tap connected to the pump 49a by the pressure of the pump 49a.

  Furthermore, an orifice plate 52 shown in FIG. The orifice plate 52 is a flat plate and has a plurality of orifice holes 54 in this embodiment. The orifice plate 52 is provided approximately at the center in the longitudinal direction of the tank body 12 perpendicular to the tube axis of the tank body 12. One of the two orifice holes 54 is disposed at the upper part of the tank body 12, and the other orifice hole 54 b is disposed at the lower part of the tank body 12.

  Normally, tap water flows into the tank body 12 from the water supply pipe 24 and passes through the two orifice holes 54. At this time, since tap water is introduced from the tank body 12 having a large diameter into the orifice hole 54 having a small diameter, the flow rate of the tap water increases when passing through the orifice hole 54, and the tap water in the tank body 12 is Stirred over a wide range and at high speed. Therefore, the tap water in the tank main body 12 circulates to the corner of the tank main body 12 and is kept more sanitary.

  In an emergency, when the water supply pressure stops working, the tap water in the tank body 12 mainly flows through the lower orifice hole 54b to the water supply port 32e at the bottom of the tank body 12, and the air is sucked from the intake / exhaust valve 42. And supplied through the upper orifice hole 54a.

  The tank body 12 of the embodiment shown in FIGS. 5 to 7 may be tilted as shown in FIG. 3 (A), or instead of the tank body 12 of the embodiment shown in FIGS. The tank body 43 shown may be used.

  Although the tank main body 51 of the water storage tank 10 which is another Example of this invention shown in FIG. 8 is substantially the same as the tank main body 12 shown in FIG. 2, the connection method of a water pipe is different. The tank body 12 shown in FIG. 2 is provided with a plurality of water supply ports 32, and the water distribution pipes 34 are directly connected to the water supply ports 32. The tank body 51 shown in FIG. , 153, a water distribution pipe 55 is connected to one water supply port 53, and the water distribution pipe 55 is branched. Since other parts are the same as those of the tank body 12 shown in FIG.

A water supply pipe 24 is connected to the introduction port 30 of the introduction surface 26. Further, for example, two water supply ports 53 and 153 are provided on the lead-out surface 28, and the water supply port 153 is disposed above the water supply port 53. The water distribution pipes 55 and 155 are connected to the water supply ports 53 and 153, respectively, and the water distribution pipe 155 is connected to a normal water intake tap in the house. Further, a plurality of water distribution pipes 55 are branched into five water distribution pipes 55a, 55b, 55c, 55d, and 55e in this embodiment, and each water distribution pipe 55 is connected to a normal water intake tap in the house. One of the water distribution pipes 55e is bent downward, and is connected to a water tap 16a of the bathroom 16 shown in FIG. 1, for example. The water tap 16a of the bathroom 16 is normally used as a water intake tap during normal times, but is used as an emergency water intake tap during emergency situations. The other water distribution pipes 55a, 55b, 55c and 55d are arranged above the bent tank body 51 on the upper side, and are usually connected to a water intake faucet, for example, a water faucet in a toilet or a toilet tank.

  In this way, the water distribution pipes 55a, 55b, 55c, and 55d that are not connected to the emergency water intake but only to the normal water intake are bent and arranged above the tank body 51, and the water supply port 153 to which the water distribution pipe 155 is connected is provided. If the siphon phenomenon is prevented by arranging an intake means such as the intake / exhaust valve 42 to be disposed above the water supply port 53, the tap water in the tank body 51 flows into the distribution pipes 55a, 55b, 55c, 55d, 155. Absent. For this reason, the tap water in the tank main body 51 flows only into the water distribution pipe 55e connected to the emergency intake tap, and the tap water in the tank main body 51 can be taken out from the emergency intake tap without waste.

  Although the water supply ports 53 and 153 are provided on the outlet surface 28, only the water supply port 53 may be provided without providing the water supply port 153.

  Further, the introduction surface 28 may be formed in a conical shape protruding toward the outside of the tank body 51, and the water supply port 53 may be provided on the top of the conical shape.

  Furthermore, the tank main body 51 can be inclined and the tank main body 43 shown in FIG. 4 can be used instead of the tank main body 51. Moreover, the tank main body 51 can be arrange | positioned in the underground 46 (FIG. 1) etc., the water intake 48 shown in FIG. 5 etc. can be provided in the tank main body 51, or the pump 49a etc. of FIG. 6 can be connected. Furthermore, the orifice plate 52 shown in FIG.

  A water storage tank 10 according to another embodiment of the present invention shown in FIG. The tank body 56 includes a plurality of tank bodies 58 in this embodiment, and the three tank bodies 58 are connected in parallel by the introduction pipe 60 and the water pipe 34, for example, above the bathroom 16 (FIG. 1). Placed in.

  The tank body portion 58 is a pipe made of synthetic resin such as hard vinyl chloride or polyethylene having a diameter smaller than that of the tank body 12 shown in FIG. 2, and both openings thereof are closed by the introduction surface 26 and the lead-out surface 28. The total internal capacity of the three tank main body portions 58 is 45 liters, for example.

  An introduction port 30 is provided on the introduction surface 26, and an introduction pipe 60 is connected to the introduction port 30. The introduction pipe 60 is connected to the water supply pipe 24, and is connected to each of the three tank body portions 58, for example. In the lead-out surface 28, a plurality of, in this embodiment, two water supply ports 32 are provided. One of the upper water supply ports 32f is located at the uppermost part of the tank body 58 and is connected to the water distribution pipe 34f.

Connected to The water supply pipe 84 extends in a direction perpendicular to the introduction pipe 82, penetrates the side surface 70 a of the case 70, and is connected to the water pipe 22 (FIG. 1). Further, the water supply pipe 84 is provided with a valve 86 and a check valve built in the valve 86. Further, the second receiving port 80b of the first cap portion 76a of each tank body portion 72 is used as a water supply port. The first water distribution pipe 88a is joined to the second receiving port 80b, and the three first water distribution pipes 88a are connected to one first water distribution main pipe 88b. The first water distribution main pipe 88b is located below the water supply pipe 84 and extends in a direction orthogonal to the first water distribution pipe 88a. And it penetrates the side surface 70a of case 70, and is connected to the normal water intake tap utilized as an emergency water intake tap at the time of emergency.

  The 1st receiving port 80a of the 2nd cap part 76b of the three tank main-body parts 72 is utilized as a water supply port. A second water distribution pipe 88c is joined to each of the first receiving ports 80a, and the second water distribution pipe 88c is bent at a right angle while maintaining the same height as the first receiving port 80a and penetrates the side surface 70a of the case 70. Usually connected to a water tap.

  The 2nd receiving port 80b of the 2nd cap part 76b of the 3rd tank main-body part 72a and the 4th tank main-body part 72b is utilized as a water supply port, and the 3rd water distribution pipe 88d is joined to each of the 2nd receiving port 80b. The third water distribution pipe 88d bends upward and extends to the same height as the first receiving port 80a, bends at a right angle therefrom, and the intake pipe 90 is connected to this position. The third water distribution pipe 88d and the intake pipe 90 pass through the side surface 70a of the case 70, the tip of the intake pipe 90 opens as an intake port 90a, and the third water distribution pipe 88d is normally connected to a water intake tap.

The 2nd receiving port 80b of the 2nd cap part 76b of the 5th tank main-body part 72c is utilized as a water supply port, and the 4th water distribution pipe 88e is joined to the 2nd receiving port 80b. The fourth water distribution pipe 88e extends at the same height as the second receiving port 80b, passes through the side surface 70a of the case 70, and is connected to the normal water intake tap. As this normal water intake tap, a normal water intake tap of non-pressure / non-supply water that does not operate without pressure such as a washing machine or a water heater is used.

  The introduction pipe 82, the water supply pipe 84, the water distribution pipe 88, and the intake pipe 90 are formed of synthetic resin or the like.

  When tap water is supplied to such a tank main body 68, the tap water flows into the tank main body portions 72 through each of the three introduction pipes 82 that branch from the water supply pipe 84 through the water supply pipe 84. At this time, if the normal water tap connected to the second water distribution pipe 88c of the first receiving port 80a of the second cap portion 76b is opened, air in the tank body portion 72 is released from here, so an air valve is provided. Even if not, the tap water smoothly flows into each tank body portion 72 and fills each tank body portion 72.

  As shown in FIG. 20C, the tap water flows from the first receiving port 80a of the first cap portion 76a in a direction perpendicular to the tube axis of the tube portion 74, and draws a circle along the inner surface of the side wall 78. It flows like. Thereby, tap water advances to the direction of the 2nd cap part 76b, while the water pressure to a pipe-axis direction is reduced. Moreover, since the diameter of each tank main-body part 72 is larger than the diameter of the water distribution pipe 88, and tap water is supplied to the several tank main-body part 72 from the one water supply pipe 84, the water flow produced with the normal water intake tap is carried out. The pressure is relieved in the tank body portion 72. Moreover, the water pressure of tap water reaching the second cap portion 76b is further reduced by the curved bottom surface of the second cap portion 76b. For this reason, even if the normal water intake tap of the second water distribution pipe 88c is not opened and the pressure of the air in the tank main body portion 72 rises, the tank main body portion 72 is not destroyed by the initial water flow, and the water storage Water can be safely stored in the tank 10.

  And as shown in FIGS. 15-19, since tap water is supplied to the tank main-body part 72, while the air in the tank main-body part 72 usually detaches from a water intake tap, and a tap water pressure acts on tap water, Each of the three tank main body portions 72 is filled with tap water without air remaining in the tank main body portion 72. For this reason, the tap water inside the tank main body portion 72 is kept hygienic.

  When the tap water is taken out from the normal intake tap after each tank main body 72 is filled with tap water, the tap water in the tank main body portion 72 flows out to the distribution pipe 88 connected to the normal intake tap and is introduced accordingly. Fresh tap water is supplied from the pipe 82 to the tank body portion 72. At this time, new tap water flows in a direction orthogonal to the tube axis of the tube portion 74, and enters the tank from the receiving port 80 of the second cap portion 76b that is diagonally opposite to the receiving port 80 of the first cap portion 76a. Since the tap water in the main body portion 72 flows out, the tap water in the tank main body portion 72 is agitated and the replacement of the tap water is promoted.

  In an emergency, tap water in the tank body 72 is taken out from a normal water tap that is used as an emergency water tap. The tap water flows out from the second receiving port 80b of the first cap portion 76a to the first water distribution pipe 88a in each of the three tank body portions 72, merges at the first water distribution main pipe 88b, and naturally flows down to the normal water intake tap. To do. Thereby, the tap water in the three tank main-body parts 72 can be taken out from one normal water tap. Moreover, the tap water stored in the tank main-body part 72 can be used only by using the normal water tap used also as an emergency water tap normally, without requiring special knowledge, an apparatus, or an instrument. .

Then, as the tap water in the tank main body portion 72 flows out, air is taken into the tank main body portion 72 from the intake port 90a provided in the third water distribution pipe 88d, whereby the third tank main body portion 72a and the second tank main body portion 72a. The inside of the 4 tank main body part 72b does not become a negative pressure, and can remove all the tap water in the tank main body part 72. The fifth tank main body portion 72c is not provided with the intake port 90a, but the fifth tank main body portion 72c is connected to the third tank main body portion 72a and the fourth tank main body portion 72b by the introduction pipe 82 and the water supply pipe 84. Therefore, the air in the third tank main body portion 72a and the fourth tank main body portion 72b is taken into the fifth tank main body portion 72c through the introduction pipe 82 and the water supply pipe 84. Therefore, the 5th tank main-body part 72c does not become a negative pressure, but tap water is taken out smoothly. In addition, since air is taken in into the 5th tank main-body part 72c from this normal intake tap also by opening the normal intake tap connected to the 2nd water pipe 88c of the 5th tank main-body part 72c, tap water is smooth. It is taken out.

  Further, a cap part is attached to the outer surface of the end of the pipe part 74, a space is formed in the cap part 76 at a position lower than the pipe bottom of the pipe part 74, and a first water pipe 88a communicating with this space is connected. By connecting an emergency water intake to the second receiving port 80b, the tap water in the tank body 72 is collected by flowing into the space below the pipe bottom without tilting the tank body 72 in an emergency.
