The gist of this paper is the three-dimensional hydroponic system that is the main feature of this project.

(Function) The three-dimensional hydroponic apparatus of the present invention is particularly advantageous in that when the solution overflows from the liquid outlet, it mixes enough air and flows out through the circulation supply piping in the form of large continuous bubbles. For all of the pots, a culture solution sufficiently mixed with air is suspended and circulated to spread it over the entire area inside the pot.

(Embodiment) To explain in more detail with reference to the drawings showing an embodiment of the present invention, reference numeral 1 denotes a support, and the support 1 has a vertical support 2.
is fixed. Further, on the support base 1, a water tank 3 and a pump 4 are arranged. A plurality of pot receivers 5 are attached to the support 2 in multiple stages, and a pot 6 is placed on top of the pot receivers 5.

Each pot 6 is composed of a container 7 containing a culture solution and a lid 8, and the lid 8 has a hole (not shown) in the center.
The planting case 8 can be freely fitted into the hole. For planting, there are a plurality of holes in the bottom of the case 9, through which roots of the plants extend into the culture solution.

13 is a liquid inlet provided on the lower side of the container 7;
is a liquid draining pipe that penetrates the bottom of the pot 6, and the liquid draining pipe 1
0 is open at the top of the lid 8. A liquid outlet 11 is included in the upper side surface of the liquid outlet pipe 10 in the container 7 . 1
Reference numeral 2 denotes a connecting pipe, which connects the lower end of the liquid outlet pipe 10 of the upper pot 6 and the liquid inlet 13 of the lower pot 6.

Reference numeral 14 denotes a liquid inlet pipe that takes the culture solution from the water tank 3 into the pump 4, and 15 indicates a liquid supply pipe that sends the culture solution from the pump 4 to the liquid inlet 13 of the pot 6 on the uppermost stage.

In addition, 16 is a plant that is grown hydroponically, and 1 "7
is the water level float in tank 3.

Next, a method of using the three-dimensional hydroponic apparatus of the present invention will be explained. The culture solution placed in the water tank 3 is supplied from the liquid inlet 13 of the pot 6 on the uppermost stage via the liquid inlet pipe 14, the pump 4, and the liquid supply pipe 15. The culture solution is supplied to the pot 6 at the top, and when the water level reaches the outlet 11, it overflows and the outlet Vi, pipe 1
Ejected from 0.

The discharged culture solution is supplied into the pot 6 from the solution inlet 13 of the lower pot 6 via the connecting pipe 12. As described above, when the water level in the lower pot 6 reaches the liquid outlet 11, the liquid overflows and is discharged from the liquid drain pipe 10. Thereafter, the lower pots 6 are filled with the culture solution one after another in the same manner. The culture solution filled in the lowermost BOBTORO is discharged from the liquid outlet 11, and the liquid is discharged from the liquid outlet 10°.
The water is refluxed to the water tank 3 through the

The culture solution is circulated and supplied through such a circulation path, and the feature of the hydroponic apparatus of the present invention is that consideration is given to distributing the culture solution with dissolved air over the entire area of the pot 6 as much as possible. .

When the culture solution is returned to the water tank 3 through the outlet pipe 10°, air is sufficiently dissolved in the culture solution in the water tank 3 by dropping the culture solution from above the liquid surface. Furthermore, an air mixing device may be placed within the water tank 3 if necessary. In this way, the culture solution in which air has been sufficiently dissolved is transferred to the liquid inlet pipe 1.
4, the top pot 6 via the pump 4 and the liquid supply pipe 15
The liquid is poured into the pot 6 through the liquid inlet 13 provided on the lower side surface. Since the liquid is discharged from the outlet 11 provided at the upper part of the pot 6, the culture liquid with sufficient air dissolved therein flows from the bottom to the top, and the culture liquid with the air dissolved spreads over the entire area inside the pot 6. . This provides favorable conditions for the growth of the roots of the plant, promotes the growth of the roots, and results in good growth of the entire plant. Also, when keeping goldfish, tropical fish, etc. in pot 6, it is even more F! It's convenient. If the air-dissolved culture solution is supplied from above the pot 6 as in the prior art,
The culture solution flows directly to the liquid outlet 11, and the air-dissolved culture solution does not spread throughout the pot 6.

Next, when the culture liquid is discharged from the liquid outlet 11 by overflow, the culture liquid falls to the liquid level of the lower pot 6 in the liquid outlet pipe 10, is thoroughly mixed with air, and the culture liquid is re-discharged. Air is sufficiently dissolved inside.

This culture medium 1f ra is also poured into the lower pot 6 through the liquid inlet 13 on the bottom back side and discharged from the upper liquid outlet 11, so that the culture liquid with sufficient air dissolved will cover the entire pot 6. What will happen is the same as described above.

In this way, the culture solution in which air has been sufficiently dissolved is well distributed throughout the pots 6 in each stage.
This is convenient for plant cultivation and for keeping goldfish and tropical fish in the pot 6.

Plants are first planted in a solid medium (such as rock wool) placed in a case 9, and then inserted into a hole in the lid 8 of a pot 6 in this three-dimensional hydroponic device. be planted in Replanting can be easily done by replacing the entire case 9.

(Experiment example) Inside the bot in the pot used in the conventional device shown in Fig. 3 (hereinafter referred to as the “conventional pot”) and the pot used in the device of the present invention (hereinafter referred to as the inventive pot) The dissolved oxygen content comparison test will be explained with reference to a schematic explanatory diagram.
