Description

  The present invention relates to a water storage tank, and more particularly to a water storage tank suitable for use in storing water for an emergency.

As a measure for securing drinking water in the event of a long-term water outage due to an earthquake or other disaster, water that has passed through the sealed water tank while connecting a sealed water tank to the water pipe and flowing water into the sealed water tank during normal times to store water Is known as a circulating storage water storage tank that uses water as a tap water and uses water in a sealed water tank in the event of a disaster (see, for example, Patent Document 1).
According to this configuration, the supply pipe connected in series with the water pipe, the sealed water tank, and the sealed water tank and the discharge pipe are not separable, so they cannot be carried in an emergency, and the floating air valve is installed. The apparatus becomes large and expensive, such as necessary.

On the other hand, a water storage tank and an emergency water storage cap provided with a water storage tank that can be easily carried and separated from the water supply pipe and drain pipe connected to the water pipe simply by removing the cap from the water storage tank Is also known (see, for example, Patent Document 2).
The invention disclosed herein is provided with a cap that allows the opening of the water storage tank to be sealed and detachable, and the water storage tank can be easily separated from the water supply pipe simply by removing the cap from the water storage tank. . In addition, since the water storage tank is a poly tank that is often used in ordinary households, it is inexpensive and portable.

However, the prior art has a common drawback. That is, since tap water supplied from the upstream of the water pipe passes through the water storage tank (or sealed water tank), the tap water in the water storage tank is replaced with new tap water by discharging water from the faucet.
However, in Patent Document 1, it is replaced with new water supplied from the upstream side when the sealed water tank 1 is full, but the water channel from the sealed water tank to the floating air valve 4 is shown in FIG. 13 (shown in the principle diagram). In this way, the float 90 in the float type air valve is pushed up by water and the passage is blocked. Therefore, when the sealed water tank 1 is full, water stays in the water channel and the water surface 91 is trapped in the valve. The bacteria in the air propagate from the floating air valve into the water in the water channel connecting the sealed water tank 1 and the floating air valve 4. When the water cut-off occurs, the water intake 3 is opened and the water level in the sealed water tank 1 drops below a certain level. Water in the water channel connecting the floating air valve to the sealed water tank 1 also enters the sealed water tank, and bacteria in the water channel also enter the sealed water tank. It enters the inside and eventually gets taken out of the water intake and enters the human mouth, resulting in a health hazard.

  Similarly, in Patent Document 2, the tip of the drain-side pipe 13a that passes through the disk 13 that seals the opening of the water storage tank faces the water storage tank protrudes from the disk 13, so When the water level of the entering tap water rises and reaches the tip of the drain side pipe 13a facing the water storage tank, the air is confined in a compartment formed by the water surface, the water storage tank inner wall surface, and the disc 13. And can hold air. In this state, the tap water further entering the water storage tank is drained from the water storage tank through the drain side pipe 13a, so that the trapped bacteria in the air propagate through the water surface in contact with the air.

  In Patent Document 3, the inner diameter of the injection portion 2 to be connected is considerably larger than the inner diameter of the flexible hose 5, and a cylindrical wall surface exists between the opening surface of the injection portion 2 and the tank top wall surface 8. Can be seen from the drawing. From this, the cavity represented by the product of the area obtained by subtracting the cross-sectional area of the water column poured from the flexible hose 5 from the cross-sectional area of the injection part 2 and the height from the opening surface of the injection part 2 to the tank top wall surface 8. It can be seen that exists. Therefore, as in Patent Document 2, an air pocket is generated in the cavity due to the rise of the water surface. As a result, the bacteria in the air in the air reservoir propagate each time in the water.

It was made on the background as described above, and is separated between the water surface that is poured into the water tank and rises, the inner surface of the water tank, and the water surface, the inner wall surface, and the lid member that seals the water tank opening surface. An object of the present invention is to provide a portable water storage tank with a lid that prevents air from being formed and prevents bacteria from growing in the water in the water storage tank.

  A feature of the present embodiment is a water storage tank according to claim 1.

A first embodiment of a water storage tank according to the present invention will be described with reference to FIG.
1 is capable of sealing the opening of the black resin tank member 6 having a capacity of 3 liters which is formed so as not to form a compartment between the water surface which is poured into the hollow portion and rising and the inner surface of the hollow portion, and is opened at the highest portion of the hollow portion. And a lid member detachably connected,
A through hole 1b is provided on the lower surface of the joint base 1d, which is a hollow body in which the plan view area of the hollow portion 1a is larger than the plan view area of the opening of the tank member 6, and the joint base surrounds the through hole 1b. An opening of the tank member 6 that is integrally connected to 1d is engraved on the inner peripheral surface of the hollow portion 1c that is open to the male screw 6a that is formed on the outer peripheral surface of the mouth portion via the ring-shaped seal member 5. And a connecting portion 1e that is detachably connected by screwing the female screw 4 to be connected, and a base end is opened at the highest portion of the ceiling surface of the hollow portion 1a of the joint base 1d, and a tip protrudes outside the joint base 1d. A cylindrical drainage pipe 3 that can be detachably connected to a drainage channel H that is connected to a faucet, such as a faucet E, and a base end that is opened in a hollow portion 1a of a joint base 1d and that passes through a through hole 1b. Can be extended to the bottom of the hollow portion of the tank member 6 A tubular water supply pipe 2 that protrudes outside the joint base 1d and is detachably connectable to a water supply path P to which a water meter M is connected. The hollow portion 1a of the joint base 1d is a water supply pipe. 2 extension part base end (the base end of the extension pipe 7 can also be penetrated into the hollow part 1a) can be accommodated, and is located above the top part 6c of the tank member to be connected. The tank member 6 is communicated with and connected to the hollow portion 1b through 1b.

The operation of the above configuration will be described.
First, the water supply pipe 2 and the water meter M are connected through a water pipe P to which a closed water stop valve W1 is connected (a check valve is inserted between the water meter M and the water stop valve W1). In addition, the drain pipe 3 and the faucet E are connected via a water pipe H to which a closed water stop valve W2 is connected.
Next, when the water stop valve W1 is opened after the faucet E and the water stop valve W2 are opened, tap water passes through the water supply pipe 2 through the water pipe P and is supplied into the hollow portion of the tank member 6 through the extension pipe 7.
The water surface in the hollow part of the tank member 6 rises as time passes. As the water surface rises, the air in the tank member 6 is chased upward, and when the water surface exceeds the mouthpiece 6c , the air is completely discharged from the tank member 6 and all the air is formed in the lid member 1. 1b, moved to the hollow part 1a. When the water level further rises, the air is discharged from the faucet E through the water pipe H from the drain pipe 3, and the tap water that has pushed out the air is also discharged from the faucet E.
In this way, the air is completely discharged from the hollow portion from the water meter M through the tank member 6 to the tap E. Thereafter, the tap E is closed if there is no need to use tap water. Next, when the faucet E is opened as necessary, water from the upstream of the water pipe is discharged from the faucet E via the tank member 6. At this time, each time the water is discharged from the tap E, the water in the tank member 6 is replaced with new tap water supplied from the upstream side of the water pipe, and the fresh state is maintained.

  If a water outage occurs due to a disaster or the like, after closing the water stop valves W1 and W2, remove the water pipes P and H, and install the tank member 6 with the water stop valve and the lid member 1 connected to the required place. Carry and prepare for use. (It goes without saying that the lid member 1 may be removed and replaced with a commonly used lid having a U-shaped cross section after detachment from the water pipe.)

  In this embodiment, one water storage tank is disposed in the water pipe, but the present invention is not limited to this. What is necessary is just to increase the number of connections of a water storage tank according to the required reserve amount of drinking water. At this time, the drainage pipe 3 of the first water storage tank closest to the water meter M and the water supply pipe 2 of the second water storage tank are connected via two stop valves, and the nth water storage tank is sequentially formed. Is connected to the water supply pipe of the (n + 1) th water storage tank via two stop valves, and the drain pipe 3 of the last nth water storage tank is connected to the faucet side water pipe H via the water stop valve. Connect to

  In this embodiment, the water supply pipe 2 and the drain pipe 3 and the water stop valve are separated, but the present invention is not limited to this. It goes without saying that a water stop valve may be integrated in each pipe.

The lid member 1 used in the present embodiment forms a hollow portion 1a having a plan view projection area larger than the plan view projection area of the opening formed in the tank member 6, and is formed through the through hole 1b. Since it communicates with the hollow portion 6b, the following effects are obtained.
B) In a bottle having only one opening, there is no physical space for inserting a water supply pipe and a drain pipe having the same inner diameter as a water pipe installed in a general house with a small opening inside diameter into the opening. In addition, the water supply pipe and the drain pipe are disposed on the top surface of the hollow portion 1a so as to be appropriately separated, and only the water supply pipe is inserted into the opening so that the tap water can pass through the hollow portion of the tank member 6. Therefore, bottles with beverages that are commercially available in large quantities can be used.
Thereby, since the bottle after drinking a drink can be reused as a tank member, a tank member can be obtained cheaply.
B) A portable water storage tank with a lid can be provided by using commercially available 1 to 2 l bottles.

A feature of the present embodiment is a modified example of the lid member shown in the first embodiment, which is a water storage tank according to claim 1 .

When the water level further rises, air is discharged from the tap E through the water pipe H through the connection pipe 13 as a drain pipe through the hole 14 formed in the lid member 11, and the tap water that has pushed out the air is also discharged from the tap E. .
In this way, the same operations and effects as those of the first embodiment are achieved.

The lid member 11 used in the second embodiment has the following effects because the pair of holes 14 and 14 that are opened at an appropriate distance from the top surface are formed as stepped holes.
B) Compared to that of FIG.
B) Since there are two large-diameter holes 14 to which the extension pipe is connected, even if one is damaged, the other can be used.
C) Since the large-diameter side of the stepped hole is opened at the highest position on the top surface of the lid, the water surface, the inner surface of the tank member, and the lid member 11 are compared with the straight hole even if the water storage tank is installed with a slight inclination. Since the air in the formed room can escape, no compartment is formed.
D) If a pipe is connected to one of the large-diameter holes 14 with respect to a tank member having two openings and an external thread engraved on the outer peripheral surface of the mouth, nothing is connected to the water supply side cover member or the same hole 14 Otherwise, it can be used as a drainage-side lid member, so it is highly versatile.
E) Since the plan view area of the hollow portion 16a provided in the lid member 10 is larger than the plan view area of the opening of the tank member 6, the options of the connection structure between the base end of the extension pipe 19 and the water supply pipe side are widened.

A feature of the present embodiment is a water storage tank according to claim 2 .

A third embodiment of the water storage tank according to the present invention will be described with reference to FIG.
In addition, the same code | symbol is attached | subjected to the site | part used by the above-mentioned Example, and detailed description is abbreviate | omitted.
Reference numeral 20 denotes a cylindrical body in which a first opening 26a opened at the highest position of the hollow portion of the tank member 26 and a second opening 26b opened in the center of the side surface can be sealed via a ring-shaped sealing member (not shown). A black resin lid member whose one side end face is closed, and a female screw that can be screwed into a male screw formed on each of the outer peripheral surfaces of both openings of the tank member 26 is engraved on the inner peripheral surface and the top surface A tubular body 20a that communicates with a large-diameter hole opened in the central portion and has a through-hole having a smaller diameter than the hole projects from a surface facing the top surface.
Reference numeral 40 denotes an L-shaped extension pipe made of a resin having a flexibility that is detachably press-fitted into a large-diameter hole communicating with the tubular body 20a and extends to the bottom of the hollow portion of the tank member 26.

A handle 26c is integrally formed with the tank member 26.

The operation of the above configuration will be described.
Since air is lighter than water, it moves upward. For this reason, the water stop valve which selected the 2nd opening part 26b side of the side surface which exists in a low place as a water supply side, and closed the pipe body 20a and the water meter M of the cover member 20 which seals the 2nd opening part 26b.

Next, as in the first embodiment, when the water stop valve W1 is opened, the tap water passes through the pipe body 2a as the water supply pipe of the lid member 20 that seals the second opening 26b through the water pipe P. Then, it is supplied into the hollow portion of the tank member 26. As time elapses, the water surface in the hollow portion of the tank member 26 rises and reaches the second opening 26b. The top surface of the lid member 20 is attached vertically and the ceiling of the second opening 26b is inclined upward in the drawing. Therefore, the water surface rises without forming a compartment between the water surface, the inner wall surface of the hollow portion, and the lid member 20 and without accumulating air. Even when the water surface reaches the top surface of the lid member 20 of the first opening 26a, that is, the opening surface of the large-diameter hole, the air surface is not formed between the water surface, the inner wall surface of the hollow portion, and the lid member 20. Therefore, all the air in the hollow portion of the tank member 26 is moved to the tube body 20a of the lid member 20 that seals the first opening portion 26a. When the water level further rises, the air is discharged from the tap E through the water pipe H, and the tap water that has pushed out the air is also discharged from the tap E.
In this way, the same operations and effects as those of the first embodiment are achieved.

Note that the tank member 26 used in Example 3 has the same operations and effects even when (a) shown in FIG. 11 is used as the water supply side lid member and (b) is used as the drainage side lid member. However, the lid member 20 has the following advantages because the stepped hole in which the hole on the large diameter side is opened is formed at the highest position on the top surface.
B) The material is less than that shown in FIG.
B) As shown in this embodiment, if a pipe is connected to the large-diameter hole 14, it can be used as a water supply-side cover member, and if nothing is connected to the hole 14, it can be used as a drainage-side cover member. (If the lid member shown in FIG. 11 is used, (a) is limited to use on the water supply side, and (b) is also limited to use on the drainage side lid member, which increases the types of lid members and increases costs)
C) Since the large-diameter side of the stepped hole is open to the top surface of the lid, it is formed by the water surface, the inner surface of the tank member, and the lid member as compared to the straight hole even if the water storage tank is installed with a slight inclination. Since the air in the room can escape, no compartment is formed.

  A feature of the present embodiment is a water storage tank according to claim 3.

A fourth embodiment of the water storage tank according to the present invention will be described with reference to FIG.
In addition, the same code | symbol is attached | subjected to the site | part used by the above-mentioned Example, and detailed description is abbreviate | omitted.

Further, a flow meter K with a throttle valve is connected to the pipe G on the connecting portion 13 side of the water supply side lid member 11.
Then, after opening the faucet E, the faucet-side water stop valve W is opened sequentially from the upstream side to the upstream side. Finally, when the water meter M-side water stop valve W is opened, the tap water is supplied through the water pipe P. 11 is supplied to the hollow portion of the tank member 46 through the extension pipe 19 through the connecting portion 12 as a water supply pipe.

The water surface in the hollow part of the tank member 46 rises as time passes.
When the water surface reaches the top surface of the lid member 11, that is, the opening surface of the hole 14, an air pocket is formed between the water surface and the inner wall surface of the tank member 46 or between the water surface and the inner wall surface of the tank member 46 and the lid member 11. Since it does not occur, all the air in the hollow part of the tank member 46 is in the hole 14 of the water supply side cover member 11 and the hollow part of the connection part 13 and the holes 14 and 14 of the drain side cover member 11 and the connection part 12 and the connection part. It is moved to 13 hollow parts.
When the water level further rises, the water surface is connected to the drain pipe 13 of the water supply side lid member 1 and the pipe G, the connection position of the pipe F and pipe G, and the water pipe H connected to the drain pipe 13 of the drain side lid member 11. And the pipe G are raised in the order of the connection position, the air is discharged from the tap E through the water pipe H to which the drain pipe 13 of the drain side lid member 11 is connected, and the tap water that has pushed out the air is also discharged from the tap E. The As a result, air is completely discharged from the hollow portion from the water meter M through the tank member 46 to the faucet E.

  Here, since the lid member 11 having the connecting portion 13 serving as a drain pipe is used at the water supply side opening of the tank member 46 provided with two openings on the upper surface, the water surface, the inner surface of the tank member 46 and the lid Since the air in the hollow part formed by the member 11 is completely exhausted through the connecting part 13 which is a drain pipe, no compartment is formed.

Next, in order to drain most of the tap water supplied through the extension pipe 19 through the drain side lid member 11, the throttle valve of the flow meter K with a throttle valve is throttled to reduce the flow rate in the pipe G.
At this time, since the momentum of the water flow can be visually recognized according to the throttle amount of the throttle valve, the flow rate is set to a level that does not stop the water flow. Thereby, the retention of the water of the path | route which leads to the water pipe H through the pipe G from the connection part 13 used as the drain pipe of the water supply side cover member 11 can be prevented.

  In addition, if a pipe G having a small inner diameter is used, it is possible to omit the flow meter K if a preliminary test is performed and it is confirmed that the water flow is not stopped by reducing the inner diameter of the pipe G.

Thereafter, the tap E is closed if there is no need to use tap water.
Next, when the faucet E is opened as necessary, water from the upstream side of the water pipe is discharged from the faucet E via the tank member 46. Thereby, every time water is discharged from the tap E, the water in the tank member 46 is replaced with new tap water supplied from the upstream side of the water pipe, and the fresh state is maintained.

  When a water outage occurs due to a disaster or the like, the water stop valve W is removed from the water pipes P and H and the pipes F and G, and the water stop valve and the lid member are connected to the required place in the same manner as in Example 1. The tank member 46 is carried and prepared for use.

  A feature of the present embodiment is a modification of the fourth embodiment.

A fifth embodiment of the water storage tank according to the present invention will be described with reference to FIG.

First, the connecting portion 12 which is a water supply pipe of the water supply side lid member 11 and the water meter M are connected via a water pipe P to which a closed water stop valve W is connected and a pipe of the drain side lid member 20. The body 20a and the faucet E are connected via a water pipe H to which a closed water stop valve W is connected.
Furthermore, the connection part 13 used as the drain pipe of the water supply side cover member 11 and the water pipe H are connected by the pipe G through the water stop valve W. At this time, similarly to the fourth embodiment, the connection position between the water pipe H and the pipe G is set higher than the connection position between the connecting portion 13 and the pipe G.
Next, when the faucet E is opened, the faucet side water stop valve W is opened sequentially from the upstream side to the upstream side. Finally, when the water meter M side water stop valve W is opened, the tap water becomes hollow in the tank member 46 as in the fifth embodiment. The water in the hollow part is raised and the water surface in the hollow part rises, and all the air in the hollow part of the tank member 46 is moved to the connecting part 13 which is the drain pipe of the water supply side lid member 11 and the pipe body 20a of the drain side lid member 20. When the water level further rises, the water surface is in the order of the connection position between the connecting portion 13 of the water supply side lid member 11 and the pipe G, and the connection position between the water pipe H and the pipe G connected to the pipe body 20a of the drain side lid member 20. As in the fifth embodiment, the air is discharged from the tap E through the water pipe H, and the tap water that has pushed out the air is also discharged from the tap E.
In this way, the same operations and effects as those of the first embodiment are achieved.

  A feature of the present embodiment is that the water storage tank used in the second embodiment is connected to the water storage tank used in the fourth embodiment.

A sixth embodiment of the water storage tank according to the present invention will be described with reference to FIG.
In addition, the same code | symbol is attached | subjected to the site | part used by the above-mentioned Example, and detailed description is abbreviate | omitted.
The connection part 12 used as the water supply pipe of the water storage tank shown in Example 2 and the connection part 13 used as the water discharge pipe of the drainage side lid member 11 of the water storage tank shown in Example 4 are connected by a pipe J. It is.

The operation of the above configuration will be described.
After piping as shown in FIG. 6, tap water is supplied into the hollow portion of the tank member 46 when the tap E is opened as described above. As time elapses, the water surface in the hollow portion of the tank member 46 rises. Finally, all the air in the hollow portion of the tank member 46 is moved to the tank member 6 side through the pipe J. When the tap water is further supplied, the water level in the tank member 6 rises, and all air flows from the connecting portion 13 which is the drain pipe of the lid member 11 attached to the tank member 6 through the water pipe H to the faucet E. The tap water which is discharged from the outlet and pushes out the air is also discharged from the tap E.
Thereby, the same operation and effect as in the first embodiment are achieved.

In addition, although the example which connected the water storage tank of Example 2 and Example 4 was shown in the said Example, it does not restrict to this. That is, the water storage tanks shown in the first to fifth embodiments may be connected to each other, or the water storage tanks shown in the first to fifth embodiments may be connected in combination.
In short, the drainage pipe of the most upstream water storage tank connected to the water meter and the water supply pipe of the water storage tank connected downstream thereof are connected, and the drainage pipe of the water storage tank is connected to the water supply pipe of the downstream water storage tank. It is sufficient to connect the drain pipe of the most downstream water storage tank to the faucet repeatedly.

In addition, in the Example of the said cover member 11, although the top | upper surface of the cover was made into planar shape, it is not restricted to this. That is, like the lid member 60 shown in FIG. 7, a concave surface 61 that connects the edge of the large diameter hole of the stepped hole that penetrates the drain pipe 2b from the end of the contact surface 60a with the seal member may be formed.
Thereby, even if a water storage tank is installed in a slight inclination, the air between a cover member, a tank member, and a water surface can be discharged | emitted reliably.

Similarly, as a modified example of the lid member 20, a concave surface 71 that connects the edge of the large-diameter hole of the stepped drain hole from the end of the contact surface 70a with the seal member is formed as a lid member 70 shown in FIG. It may be opened at the highest point on the top.
Thereby, even if a water storage tank is installed in a slight inclination, the air between a cover member, a tank member, and a water surface can be discharged | emitted reliably.

  Moreover, although the cover member of the said Example showed what the outer peripheral wall and the bottom face were integrally molded, it does not restrict to this. That is, as shown in FIG. 9 as a modified example of the lid member 11, the lid member 80 is threadedly engaged with a male screw engraved on the outer peripheral surface of the mouth of the tank member while the hole 80a is penetrated through the top surface. A ring cap 81 engraved with a possible female screw and a side end face facing the hole 80a of a disk accommodated in a hollow portion of the ring cap 81 and having an outer diameter larger than the inner diameter of the hole 80a. The water supply pipe 82a and the drain pipe 82b through which the stepped hole is penetrated are provided so that the large diameter hole of the stepped hole is configured as a lid 82 that is opened at the other end face facing the one end face. Good.

  Similarly, as a modified example of the lid member 20, one side end face facing the hole 80a of the ring cap 81 and a disc accommodated in the hollow portion of the ring cap 81 and having an outer diameter larger than the inner diameter of the hole 80a. A tube body through which one stepped hole is penetrated in the central portion may be protruded, and a large-diameter hole may be configured with a lid that is engaged with the other side end surface facing the one side end surface.

  Moreover, the hole penetrated by the lid member is not limited to the stepped hole. That is, as shown in FIG. 10 as a modified example of the lid member 11, if the water supply pipe side protrudes into the inside of the lid member with a straight hole, the drain pipe opens to the highest position on the top surface. Available to: At this time, the outer peripheral surface of the water supply pipe is inserted and connected to the hollow portion of the extension pipe.

  Moreover, although the connection means of a cover member and a tank member opening part and a cover member and a coupling member opening part was set as the structure which screws a male screw and a female screw, it is not limited to this. That is, as shown in FIG. 12, the flange provided around the outer periphery of the mouth of the tank member and the flange provided around the outer periphery of the mouth of the lid member may be hermetically connected via the sealing material. In short, any connecting means may be used as long as the connection surface between the lid member and the tank member opening is airtightly connected so as not to cause air accumulation.

  Further, although the lid member and the tank member are black, the present invention is not limited to this. That is, the color which permeate | transmits sunlight, such as transparency and white, may be sufficient. In this case, it is preferable to cover the water storage tank with a lid with a black sheet that prevents the transmission of sunlight, or store it in a dark room. In short, any color may be used as long as secondary treatment is performed to block sunlight so as to prevent photosynthesis of green algae or the like that have entered the water in the water storage tank.

  In addition, if the storage tank is made of a color or material that does not allow sunlight to pass through, it can be used as a heat collector for solar water heaters installed on the roof or rooftop, so it is usually used as a solar water heater and is used for emergency drinking Can be used as water.
