Field of the Invention The present invention relates to a plant cultivation apparatus used for research and experiments in agriculture such as breeding or cultivation of plants. The present invention relates to a plant cultivation apparatus including a light source chamber in which an artificial light source for cultivation is arranged, and capable of circulating at least temperature-adjusted air in the cultivation chamber to artificially control environmental factors.

For example, the one shown in FIG. 4 is known. In this plant growing apparatus 1, a growing room 2 partitioned by respective face walls is installed in a machine main body 1a, a ceiling surface of the growing room 2 is formed of a transparent glass plate 2c, and a plurality of lamps 3
The light source room 3 in which b is arranged is installed.

している。[0003] The growing room 2 is shut off from the outside,
In the breeding room 2, air whose temperature and humidity are adjusted is circulated at all times. That is, an air blowing portion 2a is provided on one side wall side and an air suction portion 2b is provided on the other side wall of the side walls partitioning the growing room 2, and these are mutually connected via a machine room 4 below the growing room 2. It communicates and forms an air circulation path.

出させていた。In the machine room 4, air adjusting means such as a cooling coil 5, an electric heater 6, a humidifying nozzle 8, a blower 7 and the like are arranged, and the air adjusting means controls the temperature and the like of air circulating in the air circulation path. The humidity is appropriately adjusted, and the adjusted air is blown out from the air blowout section 2a into the growth chamber 2, circulated through the growth chamber 2, and then discharged from the air suction section 2b into the air circulation path.

いる。かかる光源室３内にはランプ３ｂが放出する膨大
な熱量が蓄積されるために熱量を放出させる必要があ
り、光源室３の外郭の要所には、熱を放出するために外
気を吸排気する通風口３ａが随所に開設されていた。The light source chamber 3 is isolated from the growth chamber 2 by a glass plate 2c and is isolated from the air circulation path. Since a huge amount of heat emitted from the lamp 3b is accumulated in the light source room 3, it is necessary to release the heat amount. A key part of the outer periphery of the light source room 3 takes in and exhausts outside air to release the heat. Vents 3a were established everywhere.

【発明が解決しようとする課題】しかしながら、前述し

め、光源室３内に外部の塵や埃が侵入し易く、ランプ３
ｂの球体表面や反射板等に塵や埃が付着して光強度の低
下を招くおそれがあった。However, in the conventional plant growing apparatus 1 as described above, the light source chamber 3 is opened to the outside through the ventilation port 3a, unlike the growing chamber 2, to release the heat in the light source chamber 3. Since ventilation is performed by introducing outside air, external dust and dirt easily enter the light source chamber 3 and the lamp 3
There is a possibility that dust or dirt adheres to the surface of the sphere or the reflection plate of b, resulting in a decrease in light intensity.
【０００７】このような問題点に鑑みて、光源室３を外

室３内を冷却する方式もあるが、この冷却方式では、外
気導入はしないため塵や埃の侵入はないのだが、光源室
３専用の冷凍機のみならず、これに付随するダクトワー
ク等の装置構造が複雑となり、コストが嵩むという問題
点があった。In view of such problems, there is also a method of cooling the inside of the light source chamber 3 using a refrigerator (not shown) without opening the light source chamber 3 to the outside. There is no intrusion of dust and dirt because it is not introduced, but there is a problem that not only a refrigerator dedicated to the light source chamber 3 but also an associated device structure such as a ductwork is complicated and the cost is increased.
【０００８】また、前述した何れの冷却方式において

板２ｃの透光性が損なわれ光強度が低下する等の問題点
があった。In any of the above-mentioned cooling methods, the growth room 2 and the light source room 3 form a space separated from each other, and the temperature and humidity of the two rooms 2 and 3 are different from each other. Under the conditions, dew condensation occurs on the glass plate 2c that blocks the growing room 2 and the light source room 3 and gives an unpleasant appearance, and the dew drops on the plants in the growing room 2 and the light transmitted through the glass plate 2c. There is a problem that the lightness is reduced and the light intensity is reduced.

凍機で冷却または加熱して前述の結露を防ぐことも考え

よりいっそう装置構造が複雑になり、コストの高騰を招
くという問題が生じる。Further, in the case of a cooling system using a refrigerator, it is conceivable to cool or heat the light source room 3 with a refrigerator so as to be close to the same temperature as the growth room 2 to prevent the above-mentioned dew condensation. This requires a special control system separately,
There is a problem in that the structure of the device becomes more complicated and the cost rises.

成装置を提供することを目的としている。The present invention has been made in view of the above-mentioned problems of the prior art, and can prevent dust and dirt from entering the light source chamber, resulting in a simple structure and an increase in cost. It is another object of the present invention to provide a plant growing apparatus capable of suppressing the occurrence of dew condensation by making the temperature and humidity of the growing room and the light source room substantially equal to each other.

の植物の導入や取り出しも容易となる。The air suction part 32 on the side of the suction hole plate 23 of the growth chamber 20 has a negative pressure due to the operation of the blower 51, and the air in the growth chamber 20 has the air suction part 32 forming the air suction part 32. The air is sucked and discharged from the suction hole 23a of the hole plate 23 to the outside of the room. Thus, according to the present apparatus 10, the growth room 20
The air blown into the room from the entire area on one side wall side is discharged outside the room from the entire area on the other side wall side.
It is possible to eliminate the temperature difference in the vertical direction in the inside, and it is possible to eliminate the temperature difference in both sides by increasing the amount of air circulation. Furthermore, in this type, since the machine room 50 is normally arranged on the side rather than below the growing room 20 due to its structure, the floor plate 21 can be set at a low position, and introduction and removal of plants into and from the growing room 20 become easy. .

The other end of the light source chamber 40 communicates with the lower end of the air blowing section 31 through the machine chamber 50. The continuous space forms an air circulation path. . That is, the air discharged from the air suction part 32 to the outside of the growth chamber 20 is directly introduced into the light source chamber 40 and passes therethrough, and is again brought to a desired temperature by the cooling coil 52 and the electric heater 53 in the machine chamber 50. It is circulated to the air blowing part 31 side by being adjusted.

実に防止することができる。As described above, since the light source chamber 40 also becomes a part of the air circulation path, excess heat generated from the sodium lamp 41 in the light source chamber 40 is constantly discharged to the outside of the light source chamber 40 together with the air flowing through the air circulation path. The excess heat is cooled mainly by the cooling coil 52 of the air adjusting means. Therefore,
There is no need to provide a refrigerator exclusively for the light source room 40, so that the cost can be reduced.
Since the temperature of the air becomes substantially equal, the occurrence of dew condensation can be surely prevented.

The structure of the apparatus is simpler than that of providing a refrigerator exclusively for 0, and can be manufactured at low cost. The temperature in the light source chamber 40 is
Since it accompanies the temperature control of the breeding room 20, it changes when the target value of the temperature in the breeding room 20 is changed. The change in illuminance is insignificant and does not cause any problem.
