Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank structure for arranging a part of a house to store rainwater for use in car washing, watering a garden, and flushing a flush toilet.

[0002]

2. Description of the Related Art First, a background of utilizing rainwater will be described. Japan is one of the rainiest countries in the world, with an annual rainfall of about 1750 mm / m ^2, which is the world average of 970.
It is almost twice as large as mm / m ² . However, the population density is high, and the per capita population is about 5460 m ^3, which is the world average of 2687.
It is about ⅕ of 0 m ³ , and because of the steep topography, much rainwater immediately flows out into the sea through the river,
The amount of water available is even more limited, with only about 870 m ³ actually available. Under these circumstances, the amount of water supply has increased with the increase in urban areas these days.
Water shortages are becoming more serious. On the other hand, in urban areas, rainwater is drained directly into the sewer through the gutter and eventually flows into the sea, so groundwater cannot be secured, which increases the impervious area of groundwater. The rise in surface temperature is a factor that causes urban heat islands.

Under these circumstances, it is sufficient to use rainwater effectively for car washing and irrigation of gardens without using clean water, and the amount of clean water used can be saved accordingly. In addition, if rainwater is effectively used for irrigation and the like, it is possible to recharge groundwater. From the above, it has been attempted to adopt a structure for storing rainwater in the house so that rainwater can be effectively used. Japanese Patent Laid-Open No. 5-
Japanese Patent No. 295767 discloses a structure in which a large-capacity aquarium is provided at an appropriate place in a house.

[0004]

However, providing a water tank that requires a certain amount of capacity limits the design of the house due to its installation, complicates the construction process, and costs it. If possible, it is possible to easily install in a conventionally constructed house without considering the installation space of such an aquarium, and to save the installation space, and to effectively use the stored water for car washing, etc. A rainwater storage method is preferable. In addition, along with this, we would like to make the tank structure for water storage that requires piping work simple in structure and easy to carry out piping work, and further to take up no space for installation.

[0005]

The present invention uses the following means in order to solve the above problems. That is, as in claim 1, a rainwater storage tank made of a vertically long cylindrical body having an open upper end is arranged in a vertical shape so that rainwater is introduced into the upper end opening from a gutter arranged at the top of the building. Set up.

Further, as described in claim 2, a bottom lid having a socket portion for connecting a pipe is attached to the lower end of the rainwater storage tank formed of a vertically long cylindrical body having an open upper end.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings. 1 is an overall perspective view of a house equipped with a vertical rainwater storage tank, FIG. 2 is a front view showing the arrangement structure of the vertical rainwater storage tank, FIG. 3 is a side view of the same, FIG. 4 is a plan view of the same, and FIG. Is a front view of a vertical rainwater storage tank, Fig. 6
Is also an internal front view showing the mounting structure of the bottom lid, FIG. 7 is a partial front sectional view of the vicinity of the bottom portion, FIG. 8 is a bottom view of the bottom lid, and FIG. 9 is a sectional view taken along line XX of FIG.

The arrangement and use of the vertical rainwater storage tank VT of the present invention in a house will be described with reference to FIG. The house shown in FIG. 1 is a two-story building, and has a structure in which the roof between the first and second floors is not provided and the roof R is arranged at the top. The vertical rainwater storage tank VT of the present invention is erected vertically from below the eaves of the roof R to the floor height of the first floor. The rainwater stored in the tank is first used as cleaning water for the toilet WC arranged on the first floor. A toilet may be provided on the second floor so that the toilet wash water is introduced from the middle of the tank.

Around the house, soil is laid, planting P is provided, and a home garden F is provided, and the water in the vertical rainwater storage tank VT is used for watering these. To do. A horizontal rainwater storage tank LT is arranged next to the parking lot PK, and this storage water is used not only for toilet wash water and car wash, but also for watering the planting P and the home garden F. . In this way, the water for toilet wash water, car wash, water sprinkling, and planting cultivation is usually stored by rainwater, so it is possible to sprinkle water even when the water is short, and since tap water is not used, tap water is not used. You can save usage. Further, for planting and growing, the pavement H leading to the parking lot PK is made water-permeable, and the surrounding block BL is also made water-permeable so that rainwater can sufficiently penetrate into the soil in rainy weather. I have to. Conventionally, these are not water permeable, but when it rains, rainwater flows over the surface and flows out to the gutters, so the water retention capacity of the soil is weak, and the planting P etc. will be in a drought state soon after a little fine weather continues. It became.

In this way, if rainwater can be effectively used for water sprinkling, on the contrary, the area of planting P can be increased without increasing the amount of water supply used. If the planting P is effectively used and the vine plants are grown so as to cover the upper part and the lateral part of the terrace, as in the house shown in FIG. 1, for example, in the summer, the sunshine is blocked and the temperature rise in the room is suppressed. In the winter, by dropping more leaves, it takes in much sunlight and raises the indoor temperature, so it exerts a natural indoor temperature control function and saves heating and cooling costs.
Above all, it gives a pleasing appearance, and can also give a refreshing blessing to people passing outside the house.

Thus, the effective use of rainwater is
It contributes greatly to the saving of clean water, measures against water shortage, and planting and nurturing. Among them, the structure of the vertical rainwater storage tank VT according to the present invention will be described below.

The outline of the mounting structure of the vertical rainwater storage tank VT will be described with reference to FIGS. 2 to 4. At the eaves of the roof R,
As also shown, the gutter G is circulated, and a gutter GP is extended below a part thereof so that the lower end faces the upper end of the vertical rainwater storage tank VT. The lower end of the vertical rainwater storage tank VT is received by the pedestal 3 fixed on the foundation B on the first floor, and the vertical rainwater storage tank V is fixed.
The middle part of T is supported by a fixture 4 fixed to the wall surface of the house.

The structure of the vertical rainwater storage tank VT itself will be described with reference to FIGS. The tank body 1 is a vertically long cylinder, and can be made of a synthetic resin pipe such as a vinyl chloride pipe, which is inexpensive. At the time of arrangement, as shown in FIGS. 5 and 6, the mesh-shaped filter 5 is capped at the opening at the upper end, and the filter 5 is made to face the lower end of the call gutter GP as described above. Rainwater dripping from the lower end of the gutter GP is filtered by the filter 5
Water is stored in the main body tank 1 through. The filter 5 has its mesh structure to remove dust and prevent insects from entering. Further, at the lower end of the filter 5, the main body tank 1
A light-shielding cover plate 5a is formed so as to be fitted in the inside of the main body tank 1 so as to prevent light from shining inside the main body tank 1 and prevent algae from propagating in the stored water inside.

On the other hand, as shown in FIG. 7, a bottom cover 2 is attached to the opening at the lowermost end. The bottom cover 2 is also made of a synthetic resin pipe such as a vinyl chloride pipe, and has a diameter slightly longer than the outer diameter of the main body tank 1, and the lower end portion of the main body tank 1 is fitted into the bottom cover 2 to An adhesive is filled between the bottom cover 2 and the two members to integrate them.

As shown in FIGS. 7 to 9, the bottom cover 2 is integrally formed with socket portions 2a, 2b and 2c for fitting the connecting pipes. The bottom lid 2 is fitted into the pedestal 3 as described above, and the pedestal 3 is provided with holes into which the socket portions 2a, 2b and 2c are fitted and the pedestal 3 is As shown in FIGS. 2 and 3, since the base B is fixed so as to sandwich the base B, the socket portions 2a, 2b, 2c of the bottom lid 2 are arranged as shown in FIG.
And, as shown in FIG. 9, when it is fitted into the Oita 3, the foundation B is
It is arranged on both outsides of the base B to avoid interference with the base B. Of course, the socket fitting holes of the pedestal 3 are also formed so as to face these sockets.

In the case shown in FIG. 6, the main body tank 1
The bottom plate 1a having holes for fitting the connecting pipes is provided on the bottom of the base plate, and the bottom cover 2 is provided through the bottom plate 1a.
In this case, the bottom plate 1a is not provided, and the bottom cover 2 is directly provided on the lower end opening of the main body tank 1. Therefore, the bottom structure of the vertical rainwater storage tank VT can be easily constructed, and at the same time, the construction of the integrally formed socket portions 2a, 2b, 2c facilitates the pipe construction.

Each socket portion 2a, 2b, 2c of the bottom lid 2
A connecting pipe is inserted into each of them according to the intended use. The socket portion 2a is formed with a certain length in the vertical direction because the overflow pipe 5 of the type that is inserted into the main body tank 1 for a long time is inserted therein. The upper end of the overflow pipe 6 is arranged directly below the light-shielding cover plate 5a at the lower end of the filter 5, and when rainwater accumulates at this position, the rainwater flows into the overflow pipe 6 and moves downward. It prevents the rainwater from flowing out and overflowing from the opening (filter 5) at the upper end. The water flowing into the overflow pipe 6 may be drained to an appropriate position, or may be connected to another water storage tank and stored in this tank.

A socket portion 2b, which is formed by projecting only downward, on the opposite side of the socket portion 2a with the base B interposed therebetween.
2c is provided, and the drain pipe 7 is fitted in the socket 2b. The upper end of the drain pipe 7 is opened at the bottom position of the main body tank 1, and muddy water containing mud and the like accumulated in the bottom of the main body tank 1 can be drained through the drain pipe 7. We are trying to purify the stored water.
In addition, in winter, in order to prevent the main body tank 1 from freezing, the drain pipe 7 may be opened to completely drain the water.

Water can be distributed to various places by using the water pipe 8 fitted in the socket 2c, or by providing an opening / closing plug on the side surface of the main body tank 1 for water intake. The socket portion 2c
The water pipe 8 to be inserted into the main body tank 1 is made to project slightly above the bottom portion of the bottom lid 2 so that muddy water at the bottom portion does not flow in. Further, as described above, water is taken from the opening / closing plug on the side surface of the main body tank 1, and the water pipe 8 is used as a bypass pipe for freeze prevention,
Water may be discharged from the water pipe 8 in winter to prevent the opening / closing plug from freezing.

Since the vertical rainwater storage tank VT constructed as described above is arranged vertically, that is, in a vertically long shape, the space under the eaves is effectively used and the horizontal installation space is not required. Further, since the water pressure is largely applied to the bottom portion of the stored water due to the weight of the water itself, if the water is distributed from the bottom portion, the water can be distributed without requiring the power of a pump or the like. That is, if the water pipe 8 is used, it is possible to distribute water with a high water pressure due to its weight, and even if the water is taken from the side surface of the main body tank 1, if the water pressure is sufficiently higher than the bottom portion, the water pressure is sufficiently high. As a result, it is possible to take water with high water pressure.

[0021]

Since the present invention is configured as described above, it has the following effects. That is, since the vertical rainwater storage tank arranged as in claim 1 is configured, first, since it is a vertical tank, it does not take up space for installation, and the stored water in the tank is subjected to gravity of the water itself. The water pressure at the bottom is high, and this water pressure can be used to distribute water without using power such as a pump. Further, conventionally, because of the tank arrangement, the structure of the building itself had to be considered from the construction stage, but since the tank of the present invention is arranged vertically in the space under the eaves, almost no tank is provided in the building itself. There is no need to make installation work. For these reasons, first, in the tank arrangement and the water distribution structure, space saving and low cost can be realized.

By using the rainwater stored in the vertical rainwater storage tank thus arranged for cleaning the toilet, planting, and the like, the amount of clean water used can be suppressed, and the rainwater can be suppressed. By effective use, the water retention of the soil can be improved,
The planting can be prevented from withering even when the water is drought.

The rainwater storage tank is, as described above,
With a simple arrangement structure, it is possible to reduce costs such as controlling the amount of water used, so demand is expected, and if demand increases in this way, the number of units that effectively use rainwater will increase, and the amount of tap water used will increase. It is possible to control the whole, and to effectively contribute to the improvement of soil water retention without waste water flowing into rivers or the sea, and to contribute to the improvement of water conditions in Japan.

Further, by constructing the bottom structure of the vertical rainwater storage tank as in claim 2, the construction of the bottom and the pipes connected to the bottom can be facilitated, and the vertical rainwater storage tank is further enhanced. It can contribute to the ease of construction and cost reduction, and can be one of the factors that stimulate demand.
