Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a water tank made of plastic at the bottom of a planter, and the water in the water tank is sucked up by a water absorbent cloth to moisten the soil so that the plant is planted in the soil of the planter. The irrigation can be done from the bottom side (not from the ground side like normal irrigation, but from below the root in the soil), and it can be automatically irrigated for a long period of time so that irrigation can be saved. A bottom irrigation planter is provided.

[0002] Depending on the type of plant, there are many plants such as roses that are not allowed to be directly watered on the leaves when watering from the ground side, and from the ground side. However, it is difficult to irrigate evenly because it is disturbed by branches and leaves, so bottom irrigation, which is a method of irrigating the ground (in the soil) and evenly moistening the soil below the root, is the most common method. It is said to be suitable for growing plants.

2. Description of the Related Art Watering plants planted in planters or plant pots, that is, irrigation, is a difficult work that is carried out all year round, and various devices have been devised for this purpose.

Particularly, recently, planters have been extremely often arranged around parks, streets, buildings and the like, but in the case of these planters, unlike the case of ground planting, regular watering by a person is absolutely essential. Since it is a condition of, the management has become an extremely big problem.

Therefore, in the past, a planter made of plastic, that is, a planter having a water tank-like structure (water does not leak) is partitioned by a partition plate, and a lower part serves as a water storage tank and soil is put in the upper part for planting. Planting, a water absorbent cloth is hung from the partition plate into the water tank, and bottom watering is performed on soil plants, but these planters are specified as plastic ones, as described above, For example, it cannot be applied to the most popular concrete (leakage water) planters at present, and it is not widely used because it lacks versatility.

Therefore, the present invention has developed that the water storage portion is independently constituted as a plastic tank (or a water tank), whereby the material of the planter (concrete, porcelain, unglazed, plastic, etc.), The bottom surface irrigation type planter can be configured without being restricted by the shape (rectangular, rectangular, circular, or any other), size, etc., thereby solving the above conventional problems.

[0007]

[Means for Solving the Problems] That is, according to the present invention, a water storage tank in which an insertion hole for a water absorbing cloth is formed in a top plate (or a cover plate) and a water supply pipe is installed upright, and an overflow hole is formed in an upper part of a side plate is provided in a planter. On the top plate (or lid plate) of the water storage tank provided on the bottom, a flat plate partition plate having a planar shape and a size suitable for the inside of the planter is placed, and the partition plate has an insertion hole for the water tank. A slit for inserting a water absorbent cloth is opened at the opposite position, the water absorbent cloth is hung vertically through the slit and the insertion hole into the water storage tank, and a root-prevention net is laid on the partition plate to partition the plant roots and soil. The bottom bottom irrigation type planter, which is constructed so that the root-prevention net is filled with soil, the upper end of the water supply pipe is opened above the soil, and the lower end is opened inside the water storage tank so as not to intrude and fall below. By solving the problem, That.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment of the present invention with reference to the drawings, an insertion hole 3 for a water absorbing cloth is formed in a top plate 2 (or a cover plate), a water supply pipe 4 is established, and an overflow hole 5 is formed in an upper part of a side plate. The water storage tank 1 is provided at the inner bottom of the planter P, and a flat partition plate 6 having a planar shape and a size corresponding to the inside of the planter P is placed on the top plate 2 (or lid plate) of the water storage tank 1. Then, a slit 7 for inserting a water absorbing cloth is opened at a position of the partition plate 6 facing the insertion hole 3 of the water storing tank 1, and a water absorbing cloth 8 is vertically hung in the water storing tank 1 through the slit 7 and the insertion hole 3. , A root net 9 is laid on the partition plate 6 to prevent plant roots and soil from intruding and falling below the partition plate 6, and the soil 10 is filled on the root net 9, and the water supply pipe 4 The upper end opens above the soil 10 and the lower end opens into the water storage tank 1. Te is obtained by constituting the bottom surface irrigation type planters.

In the above description, the water-absorbent cloth 8 is made of a water-absorbent non-woven fabric in the shape of a strip, and the root-preventing net 9 is made of, for example, a non-woven fabric sheet which is slightly larger than the partition plate 6.

The partition plate 6 is formed of, for example, a flat plate made of FRC (made of glass fiber reinforced concrete), and a planter P is used.
It is divided into two pieces for easy insertion inside.

Further, according to the present invention, a rod-shaped float or a level float 1 having a float attached to the lower end of the rod is provided in the water supply pipe 4 so that the amount of water (water level) in the water storage tank 1 can be known from the outside.
1 is inserted and installed, and normally, the cap 12 is fitted into the upper opening of the water supply pipe 4, and the upper end of the level float 11 is pushed down. Therefore, at the time of water supply or inspection, if the cap is removed, the upper end of the level float 11 rises according to the water level, and the amount of stored water can be known.

In the above, one water tank 1 is installed in the planter P.
In the case of individual installation, a plurality of water storage tanks 1 are installed in the planter P according to the size and shape of the planter P and the size and shape of the water storage tank, or the required amount of water storage. In that case, the water storage tanks 1 are connected to each other at their lower portions by flexible pipes and other pipes 14. By doing so, the water supply pipe can be attached to any one of the water storage tanks 1 and water can be supplied from there, so that water can be supplied to all the water storage tanks 1 on the principle of the U-shaped pipe.

The above is a case where a plurality of water storage tanks are installed in the same planter P, but the water storage tanks of a plurality of water storage tanks having a plurality of water storage tanks can be connected to each other by a pipe 14 to form the same as above. .

[0014]

The water storage tank 1 is installed at the bottom of the planter P, the partition plate 6 is mounted on the top plate 2 of the water storage tank 1, and the insertion holes 3 for the both 2 and 6 are installed.
And the slit 7 are placed in a matched state, and the water absorbing cloth 8 is hung vertically in the water storage tank 1 through the insertion hole 3 and the slit 7.
Next, the partition plate 6 is covered with the root-preventing net 9, and the soil 10 is put into the root-preventing net 9 to fill the soil, and a plant is planted in the soil 10. In this state, the upper end of the water absorption pipe 4 projects above the soil 10.

In the above state, the cap 12 of the water suction pipe 4 is removed and water is absorbed in the water storage tank 1. The amount of water absorbed, that is, the water level in the water storage tank 1 is the level float 11 inserted in the water supply pipe 4.
Know the rising position at the top of the.

When the tank is full, excess water flows out from the overflow hole 5, flows down on the bottom plate of the planter P, and is discharged from the drain 13 of the planter P to the outside.

The water in the water storage tank 1 is absorbed by the water absorbing cloth 8 hung vertically in the water to reach the upper surface of the partition plate 6, and the soil 10 on the net 9 is passed through the root-preventing net 9 closely attached to the cloth 8.
Will be absorbed into the soil, and the soil 10 will be moistened and the roots of the plants will be watered from the bottom side.

The required irrigation amount per hour varies depending on the size of the planter, the nature of the soil, the type and number of plants, etc., but is adjusted depending on the number and position of the water absorbing cloths or the size of the water absorbing cloths.

After that, it suffices to supply water in anticipation of a decrease in the amount of water in the water storage tank. In the embodiment, the planter (outer dimensions, width 1200 mm × length 400 mm × height 42)
0mm) water tank (horizontal 860mm x vertical 325mm)
(Height 160 mm ≈ 45 liters) was installed, but the conventional above-ground irrigation system required a daily irrigation volume of about 1.5 liters in the summer when this planter was used. .5 = 30, that is, water should be absorbed once in about 30 days. Furthermore, in the case of the present invention, since the bottom surface irrigation, the natural evaporation consumption from the outer surface (ground surface) of the soil is much smaller than the conventional ground side irrigation,
Actually, continuous irrigation can be performed for a longer period than the above.

When a plurality of water storage tanks are installed in the same planter, if the vicinity of the bottoms of the water storage tanks are connected by a pipe such as a flexible pipe, only one water storage tank having a water absorption pipe is required. By absorbing water from the pipe, it is possible to store water at the same water level in each water storage tank according to the principle of the U-shaped pipe. Multiple planters (1 for each water tank
The same can be done when the individual water storage tanks are connected by pipes.

[0021]

[Effect] Since the water tank provided independently is installed in the planter, it is not limited by the material, shape, etc. of the planter, and can be installed in any planter to form a bottom watering type planter. There are excellent features to gain.

The water in the water storage tank is absorbed by the water absorbing cloth and rises to the upper surface of the partition plate, where it is absorbed by the soil on the net through the root-preventing net that is in close contact with the water absorbing cloth. It is possible to irrigate the roots from the bottom side very effectively.

Since the upper end of the water absorption pipe is opened above the soil and the lower end is opened inside the water storage tank, it is possible to freely supply water without seeing the water storage tank from the outside, and once absorbing water, it is extremely long. Since bottom watering can be automatically maintained over a period of time, there is a great advantage that the watering management of planters can be significantly reduced.

By inserting the level float into the water absorption pipe, the cap (usually pushed down into the water by the cap) is removed, and the size (scale) of the level float protruding and rising from the upper end opening of the water absorption pipe. By seeing
You can immediately know the water level (water volume) in the water storage tank.

[0025] In order to be able to install without choosing a planter,
Since the water storage tank is much smaller than the planter, when it is installed on the bottom of the planter, the water storage tank is wide and the soil is filled in that state.
When planting, the water storage tank is buried in the soil, and the roots of the plant penetrate not only around the water storage tank but also inside, which causes a significant hindrance to the subsequent maintenance. A large partition plate for manufacturing, etc. is provided in accordance with the flat area and shape of the planter, and it is placed on the water storage tank to partition the interior of the planter into a lower water tank chamber and an upper soil filling chamber firmly and clearly. At the same time, by covering the partition plate with a root-proof net that does not allow thin roots or fine soil of plants to pass through (water and breathability), roots and soil do not intrude and fall even through gaps around the partition plate. I did so,
The water storage tank can be kept in a state where it is not affected by roots or soil, which is an effect that maintenance is extremely easy.

Further, since the water storage tank has an overflow hole, even if water is supplied from the water supply pipe to a full tank or more,
Excess water flows out from the hole, flows down on the planter bottom plate, and is drained to the outside from the drain of the planter.
There is no hindrance.

When a plurality of water storage tanks are installed in the same planter, the water supply tanks may be connected to each other by a pipe such as a flexible pipe so that only one water storage tank has a water supply pipe. By absorbing water from the pipe, it is possible to supply water to each water storage tank at the same water level according to the principle of the U-shaped pipe. Also, there is an advantage that can be similarly achieved when the water storage tanks of a plurality of planters (one water storage tank each) are connected by pipes.
