Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly stores rainwater and further stores bath water and other reusable wastewater generated at home, which is effective as a tap water. The present invention relates to a storage device for simple water supply, which is designed to be reused efficiently and to save resources.

(Prior Art) General households are provided with water supply facilities for drinking and other water use at home. However, in general households, it is not always necessary to use clean water, which is, for example, as wash water for washing, flushing toilet bowls, car washes, etc., and also pots, garden trees, etc. It is used as supplementary water for planting.

In addition, in general households, in order to prevent wasteful use of the bath water as it is after use, it may be reused as washing water, makeup water for plants, etc. Many.

(Problems to be solved by the invention) Therefore, in general households, it is wasteful to use tap water other than what is used as a drink from the viewpoint of effective utilization of limited water. The situation is unavoidable. For this reason, in particular, in order to reuse the bath water after use that occurs in general households, it is pumped up by a pump, a bucket, or the like. However, handling the equipment is troublesome for the pumping up and the physical burden is large, and it is very expensive to install as so-called tap water for that purpose, and it is installed in a general household. Is difficult.

On the other hand, although rainwater is clean water purified by a natural purifying action, normally, rainwater is drained as it is by sewer facilities through a rain gutter, a sewer, and the like.

Therefore, the present inventor focused on the fact that draining natural purified rainwater as it is is a waste of resources, so that it can be easily reused as tap water,
Further, the present inventors have calculated a simple water supply storage device that enables reuse of bath water and other reusable waste water generated at home without requiring troublesome work.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a storage tank main body 1 for storing rain water, bath water generated at home and other reusable waste water, and this storage The rainwater introduction pipe 3 and the wastewater introduction pipe 6 arranged and connected to the upper part of the storage tank body 1 at a position higher than the maximum water storage surface at the time of maximum storage of the wastewater in the tank body 1, and the side wall of the storage tank body 1 are inserted. The wastewater basin 9 which is connected to the wastewater introducing pipe 6 and which is partitioned in the storage tank main body 1 at a height position substantially corresponding to the maximum water storage surface position in the upper part of the storage tank main body 1 and the storage tank main body 1 When the amount of stored water stored in is smaller than the maximum storage amount, the bottom of the wastewater basin 9 is opened, and when the amount of stored water is greater than the maximum storage amount, the bottom of the wastewater basin 9 is closed and the wastewater is left outside the storage tank body 1 as it is. A blocking valve 13 that floats above the stored water surface should be Characterized in that a waste water switching valve mechanism 10.

Further, the wastewater switching valve mechanism 10 has a water passage opening 11 formed at the bottom of the wastewater basin 9 and a water-permeable valve chamber 12 projecting downward from the bottom of the wastewater basin 9 arranged in the storage chamber. Floating above the surface of the stored water stored in the main body 1 and moving up and down,
A closing valve 13 for opening and closing 11 is provided, and the storage tank body 1
The waste water discharge pipe 15 communicating with the outside can be connected to the side wall of the waste water basin 9 to be constructed.

(Operation) In the storage device for simple tap water according to the present invention, rainwater is collected by the rainwater introduction pipe 3, and bath water or other reusable wastewater generated at home is collected by the wastewater introduction pipe 6 in the storage tank body 1 Introduced in each.

When the amount of stored water in the storage tank body 1 is not sufficient due to the introduced rainwater, wastewater, etc., the closing valve 13 in the wastewater switching valve mechanism 10 is located at the bottom of the valve chamber 12 and the bottom of the wastewater container 9 is located. By opening the, the wastewater introduced through the wastewater introduction pipe 6 is stored in the storage tank body 1 together with rainwater and the like.

Then, when the stored water stored in the storage tank main body 1 becomes the water storage surface corresponding to the maximum storage amount in the storage tank main body 1,
In the wastewater switching valve mechanism 10, the closing valve 13 in the valve chamber 12 rises with the water surface to close the water passage 11 of the wastewater basin 9. Then, the waste water is not introduced into the storage tank body 1 but overflows in the waste water container 9 and is discharged to the outside of the storage tank body 1 through the waste water discharge pipe 15 connected to the side wall of the waste water container 9.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

<Reservoir main body> Reference numeral 1 shown in the figure is a storage tank main body, and this storage tank main body 1 is installed, for example, in a site of a general house, underground, in a site of an apartment house, underground, or the like. It has a closed structure.

As shown in the figure, this storage tank main body 1 itself is subjected to heat insulation treatment 2 so that the stored water stored therein, for example, the waste water of the bathtub can be kept warm at about 30 ° C., and is used in the winter and cold seasons. Be prepared for snow melting.

<Rainwater introduction pipe> Then, as shown in the figure, the rainwater is guided and stored in the upper part of the storage tank body 1 so as to be located above the maximum storage surface when the wastewater is stored in the reservoir body 1 at the maximum storage time. A rainwater introducing pipe 3 is arranged and connected, and the rainwater introducing pipe 3 is connected to a rainwater gutter 4. Further, the rainwater discharge pipe 5 arranged and connected to the upper part of the storage tank body 1 is connected to a rainwater basin (not shown) so that the stored water stored in the storage tank body 1 is stored in the storage tank body 1. It has an overflow action that keeps the maximum position of the water storage surface at the maximum storage amount, that is, not exceeding this position. The inlet of the rainwater distribution pipe 5 is located at the bottom of the storage tank body 1 so that the overflow at this time is sequentially drained from the stored water at the bottom of the storage tank body 1.

<Wastewater Introducing Pipe> On the other hand, a wastewater introducing pipe 6 set at the same height as the rainwater introducing pipe 3 is arranged and connected to the upper part of the storage tank main body 1 separately from the rainwater introducing pipe 3. The introduction pipe 6 is connected to, for example, a wastewater pipe 8 of a bath 7. This wastewater introduction pipe 6
The waste water introduced into the storage tank body 1 by the above is not limited to bath water, and may be other reusable domestic waste water, and is not limited to bath water.

<Wastewater switching valve mechanism> Then, the bathwater and other wastewater introduced by the wastewater introduction pipe 6 are arranged at appropriate positions in the storage tank main body 1 at a suitable position substantially corresponding to the maximum water storage surface position in the upper portion of the storage tank main body 1. The wastewater introduced is once introduced into the wastewater basin 9 that is formed, and the maximum amount of the stored wastewater stored in the storage tank main body 1 is stored by the wastewater switching valve mechanism 10. When it is smaller than the maximum storage amount, the bottom of the waste water container 9 is opened, and when it is larger than the maximum storage amount, the bottom of the waste water container 9 is closed so that the waste water is discharged to the outside of the storage tank body 1 as it is.

That is, as shown in the figure, the wastewater switching valve mechanism 10 has a water passage opening 11 formed at the bottom of the wastewater basin 9 and a water passageable valve chamber 12 projecting downward from the bottom of the wastewater basin 9 arranged and connected to the water passage 11. A blocking valve 13 that floats on the water surface and closes the water passage 11 is provided in the inside 12. In addition, a trap part was
The waste water discharge pipe 15 has a structure 14 and is connected to a waste water discharge pipe 15 that goes out from the storage tank main body 1.

The wastewater discharge pipe 15 is connected to a sewage basin (not shown) so that the wastewater overflowing in the wastewater basin 9 overflows.

The valve chamber 12 is not limited to the one in which a water passage hole is formed in the bottom portion and the peripheral wall of the cylindrical body as shown in the drawing, and may be a mesh basket, but the water passage hole is not provided in the closing valve 13. It is not so large that the closing valve 13 is always held in the valve chamber 12.

On the other hand, the closing valve 13 has, for example, an air ball structure so as to ensure the closing of the water passage 11, and when this is on the inner surface of the bottom of the valve chamber 12, the water passage 11 is opened. The waste water introduced into the waste water container 9 is guided into the storage tank body 1. In addition, rainwater stored in the storage tank body 1,
When the amount of waste water reaches the maximum storage amount and the stored water surface reaches the inside of the valve chamber 12, it floats on the water surface in the valve chamber 12 (see FIG. 3).

Therefore, in the wastewater switching valve mechanism 10, when the stored water reaches or exceeds the maximum storage amount while the closing valve 13 is floating on the stored water surface that has reached the inside of the valve chamber 12, it rises and floats together with the stored water surface position. The closing valve 13 that closes the water passage 11 prevents the waste water introduced into the waste water container 9 from being introduced into the storage body 1. Then, when the waste water begins to overflow in the waste water container 9, the waste water is overflowed to the outside of the storage tank main body 1 through the waste water discharge pipe 15.

<Water Supply Pipe> Further, the stored water stored in the storage tank body 1 is pumped up by the pumping pump 16 via the water supply pipe 17 where the inlet with a filter reaches the bottom of the storage tank body 1.
For example, it is used as washing water for washing, flushing toilet bowls, car washing, etc., and as makeup water for pots, garden trees and other plantings.

<Water Supply Pipe, Ball Tap Mechanism> In the figure, reference numeral 18 is a water supply pipe arranged and connected to the upper part of the reservoir main body 1, and is opened and closed by a ball tap mechanism 19 provided at the bottom inside the reservoir main body 1. With this ball tap mechanism 19, when there is no stored water in the storage tank body 1, tap water can be automatically supplied as storage water in the storage tank body 1, for example, when the stored water is used for cleaning a flush toilet. It is possible to prevent the washing operation from being stopped due to the shortage of water.

<Passing mechanism> Further, although not shown, a suitable passing mechanism for passing rainwater, bath water, etc. is attached to the rainwater introducing pipe 3, the wastewater introducing pipe 6, the storage tank body 1 itself, the water supply pipe 17 and the like. It is also possible.

<Example of Use> Next, the use of the device of the present invention will be described. Rainwater is collected by the rainwater introduction pipe 3, and bath water generated in the home or other reusable wastewater is collected by the wastewater introduction pipe 6 in the reservoir body. Introduced in 1 respectively.

At this time, if the storage tank body 1 does not have a sufficient storage amount, not only rainwater is stored but also the water passage 11 of the wastewater basin 9 in the wastewater switching valve mechanism 10 is opened. Therefore, the waste water is also stored in the storage tank body 1.

When the amount of stored water in the storage tank main body 1 is equal to or greater than the maximum storage amount, in the wastewater switching valve mechanism 10, the closing valve 13 in the valve chamber 12 rises along with the water surface, and the water passage 11 of the wastewater basin 9 is reached. To block. Then, the wastewater is not introduced into the storage tank main body 1 but overflows in the wastewater container 9 and is directly discharged to the outside of the storage tank main body 1 through the wastewater discharge pipe 15.

The rainwater, wastewater, etc. stored in this way are transferred to the water pipe 17,
It is pumped up by the suction pump 16 and appropriately consumed and used.

Further, when there is no stored water in the storage tank body 1, the required amount of clean water is automatically introduced and supplied through the clean water pipe 18 by the operation of the ball tap mechanism 19.

(Effect of the device) Since the device of the present invention is constructed as described above, it can be effectively used as a tap water by storing rainwater, and further, recyclable wastewater generated at home such as bath water. It can be reused and can be used for resource saving.

In other words, this is because the present invention compares the rainwater, the bath water generated at home and other reusable wastewater, and the maximum storage surface of the storage tank body 1 when the wastewater is stored at the maximum. The rainwater introducing pipe 3 and the wastewater introducing pipe 6 which are arranged and connected to the upper part of the storage tank main body 1 at the upper position and the wastewater introducing pipe 6 which penetrates the side wall of the storage tank main body 1 are connected. 1 When the wastewater basin 9 partitioned in the storage tank body 1 at a height position substantially corresponding to the maximum water storage surface position in the upper part and the stored water stored in the storage tank body 1 is less than the maximum storage amount Has a closing valve 13 that floats above the stored water surface so that the bottom of the waste water tank 9 is opened and the bottom of the waste water tank 9 is closed when the amount is larger than the maximum storage amount and the waste water is drawn out of the storage tank body 1 as it is and drained. This is because the waste water switching valve mechanism 10 is attached. , It is possible to store mainly rainwater that has been purified by natural purifying action, and as a shortage, it is possible to store bath water and other reusable wastewater generated at home, which enables extremely effective reuse of water resources. To

In addition, the wastewater switching valve mechanism 10 has a water passage 11 formed at the bottom of the wastewater basin 9 and a water passageable valve chamber 12 projecting downward from the bottom of the wastewater basin 9 that is connected to the water passage 11 and stored in the valve chamber 12. A blocking valve 13 that floats above and below the surface of the stored water stored in the tank body 1 and moves up and down to open and close the water passage 11 is provided, and a waste water discharge pipe 15 that communicates with the outside of the storage tank body 1 is connected to the waste water. Since it is connected to the side wall of the basin 9, in relation to a certain amount of the stored water in the storage tank body 1, the introduction of the bath water or other waste water into the storage tank body 1 or the waste water outside the storage tank body 1 The selection can be automatically controlled, and since this control does not have a specially complicated mechanism, its maintenance is easy, there are few failures, and it operates reliably.

As described above, according to the present invention, rainwater, which is clean water purified by a natural purifying action, is mainly stored, and the shortfall can be replenished with bath water or other waste water generated at home, and the structure It's simple, it's extremely easy to install in homes, etc., easy to handle and maintain,
It has excellent practical effects such as no failure.
