    The artificial irradiation unit 11 is, for example, a light bulb, a fluorescent lamp, a light emitting diode, or the like, and the artificial irradiation unit 11 is arranged such that the opening of the attachment portion 11a of the artificial irradiation unit 11 faces downward so that the artificial irradiation unit 11 hangs down. (See FIG. 6), the attachment portion (socket) 11a is attached to a support member S provided on the upper portion of the main body 10. The attachment portion 11a is a socket that is a receiving port for inserting a light bulb, a fluorescent lamp, and a light emitting diode.

    Further, 1 shown in FIG. 4 is a floating mat, and the floating mat 1 is provided so as to float on water containing nutrients stored in the water storage unit 12. The floating mat 1 is provided with a plurality of openings 1a, and the plurality of openings 1a are provided with, for example, a medium 2 for supporting seeds or seedlings 3 of edible vegetables (the medium 2 is specifically a urethane sponge). And is commonly referred to as a “seedling pot”. That is, the culture medium 2 that supports the seedling 3 is inserted into the opening 1a and floated in water containing nutrients for cultivation.

Further, the main body 10 includes a living space (for example, a living room of a general household with air conditioning equipment) R, an air intake opening 10A for taking in the air in the R, and the air in the main body 10 as the living space. The air discharge opening 10B is discharged into the R, and the air intake opening 10A is provided below the air discharge opening 10B.
The air intake opening 10 </ b> A is formed in a size that allows plants grown in the main body 10 to be taken out of the main body 10 by hand, and the air discharge port 10 </ b> B is not the ceiling portion of the main body 10. The air discharge port portion 10B provided on the side surface is desirably provided with a first air discharge port portion 10B1 and a second air discharge port portion 10B2, and the first air discharge port portion 10B1 and the second air discharge port 10B1. As shown in FIG.2 and FIG.5, it opposes the discharge port part 10B2.
A reflecting material 14 made of aluminum foil or the like that reflects light from the artificial irradiation unit 11 is provided on the inner wall of the main body 10 excluding the water storage unit 12 over substantially the entire inner wall.
1, 3, and 6 is a drooping member, and the drooping member 10 </ b> C is provided so as to hang from the air intake opening 10 </ b> A so that the drooping member 10 </ b> C can be bent to the outside of the main body 10. Is attached via a hinge 2. The drooping member 10C faces the artificial irradiation unit 11 (see FIG. 6).
The main body 10 includes a water storage portion 12 and a covering member 13 that covers the water storage portion 12, and the water storage portion 12 is, for example, a polypropylene container having an open top (for example, a width of 450 mm, a depth of 300 mm, With a height of 180 mm and a capacity of 15000 cc), air is supplied (oxygen is supplied) to the water containing nutrients stored in the water storage unit 12 in the water storage unit 12. For example, air is supplied from an air pump (not shown) through the vinyl pipe 15 and the air stone 16. The covering member 13 has a substantially rectangular parallelepiped shape, for example.

    Therefore, according to the hydroponic cultivation apparatus P described above, a conventional hydroponics sensor and a circulation pump are not required, that is, recent Japanese buildings are fully equipped with air-conditioning equipment, heat insulation and airtightness. As the temperature of the living space R is almost suitable for the growth of vegetables and it is not necessary to air-condition and heat the device itself, the entire device can be taken in without increasing the size. Plants can be grown by taking in the air in the living space R where people live in the main body 10 through the opening 10A, and even in a light environment where sunlight is difficult to enter, It can be compensated by using the provided artificial irradiation unit 11, and further, heat is generated in the main body 11 with the provision of the artificial irradiation unit 11, but the air intake opening 10A is located below the air discharge port 10B. Provided Therefore, heat in the body 10 by natural convection generated in the main body 10 is discharged to the outside main body 10, it is possible to prevent the temperature rise in the body 10.

Moreover, since the reflecting material 14 which reflects the light from the artificial irradiation part 11 is provided in the inner wall of the main body 10, the light from the artificial irradiation part 11 can be efficiently supplied to the plant in the main body 10. In particular, the reflector 14 provided on the inner wall of the ceiling of the main body 10 can supply the plant in the main body 10, and the air intake opening 10 </ b> A allows the plant in which the seedlings in the main body 10 grow to be hand-held. Therefore, fresh and safe vegetables can be obtained at any time through the air intake opening 10A.
In addition, an opening of the attachment portion 11a of the artificial irradiation unit 11 is provided so that the artificial irradiation unit 11 hangs down, and a hanging member 10C that hangs down to the air intake opening 10A is bent to the outside of the main body 10. Since the drooping member 10C faces the artificial irradiation unit 11 (see FIG. 6), the drooping member 10C is bent outside the main body 10 and the artificial irradiation unit 11 is attached to the attachment unit 11a. Or the artificial irradiation part 11 attached to the attachment part 11a can be removed easily.
Further, the air discharge port portion 10B is provided with a first air discharge port portion 10B1 and a second air discharge port portion 10B2, and the first air discharge port portion 10B1 and the second air discharge port portion 10B2 are: Since they face each other, exhaust can be performed smoothly.

In addition, according to a present Example, the irradiation time is 10-12 hours according to a user's lifestyle using the artificial irradiation part 11 according to a user's lifestyle, using 6 22W3 wavelength daylight color fluorescent lamps, and a 24-hour timer, and nine stocks. As a result of cultivating seedlings of Komatsuna (the required amount of nutrient solution per strain is about 1500 cc) for about 5 weeks, a yield of about 50 g per strain was obtained. Note that water can be replenished, for example, using the container 6 shown in FIG. 6 through the air intake opening 10A into the water accommodating portion 12, and the amount of water replenished increases in leaf area. It was necessary to manage water frequently as the transpiration amount increased and the later stage of growth, and finally it was about 5000 cc.
In the present embodiment, an example of a seedling pot (seeded and germinated in a polyurethane foam sponge) as an edible vegetable seedling supported by the culture medium 2 is shown. In the present invention, The seeds of edible vegetables supported by the medium 2 may be replaced with seeds directly on the medium 2 so that the seeds of the edible vegetables are supported by the medium 2.
