植物用の水生成装置、植物栽培システムPlant water generator, plant cultivation system
　本発明は、植物に供給する水を生成する植物用の水生成装置、植物に自動で水を供給することが可能な植物栽培システムに関する。 The present invention relates to a plant water generating apparatus that generates water to be supplied to a plant, and a plant cultivation system capable of automatically supplying water to a plant.
　家庭菜園や観葉植物など、家庭等で、手軽に植物を育成する機会が増加している。しかし、農薬を使わずに植物を栽培すると、バクテリアやカビ・藻類の胞子の侵入によって、病害や藻類の発生が起こりやすい。 Opportunities to grow plants easily at home, such as home gardens and foliage plants, are increasing. However, when plants are grown without using pesticides, diseases and algae are likely to occur due to the invasion of spores of bacteria, mold and algae.
　また、作業者が、バケツやジョウロ等を用いて水遣りを行う場合、水を持ち運びする必要があり、手間がかかるという課題が生じる。 Also, when an operator uses a bucket or watering device to carry out watering, it is necessary to carry the water, which causes a problem that it takes time.
　そこで、特許文献１では、空気から水を生成することで、水を持ち運ばず、必要な場所で水を生成する装置が開示されている。 Therefore, Patent Document 1 discloses an apparatus that generates water from a necessary place without generating water by generating water from air.
　特許文献１には、空気から水を抽出する装置が開示されている。 Patent Document 1 discloses an apparatus for extracting water from air.
　図８は、特許文献１に記載の水生成装置５００の構成を表す断面図である。 FIG. 8 is a cross-sectional view showing the configuration of the water generating device 500 described in Patent Document 1.
　特許文献１では、水生成装置５００によって、飲み水用の水を生成している。 In Patent Document 1, water for drinking water is generated by a water generating device 500.
　図８に示すように、水生成装置５００は、熱電装置５０７と、熱電装置５０７を介して、横並びに配されているコールドシンク５０５及びヒートシンク５０６と、熱電装置５０７、コールドシンク５０５及びヒートシンク５０６の下方に配されている配管分流部５０８と、を備えている。 As shown in FIG. 8, the water generating device 500 includes a thermoelectric device 507, a cold sink 505 and a heat sink 506 arranged side by side via the thermoelectric device 507, and a thermoelectric device 507, the cold sink 505 and the heat sink 506. A pipe diverter 508 disposed below.
　さらに、水生成装置５００は、送風機５０２・５０４・５４４、及び紫外線電球５１８・５１７、紫外線光源５１５を備えている。 Furthermore, the water generating device 500 includes blowers 502, 504, and 544, ultraviolet light bulbs 518 and 517, and an ultraviolet light source 515.

　コールドシンク５０５は、熱電装置５０７の低温側と熱結合された冷却シンクフィンを備えている。コールドシンク５０５で、送風機５０２によって流入した空気を露点以下に冷却し、水滴５４２を凝縮する。そして、水滴５４２は、配管分流部５０８に設けられた流出口５０９から外部に出力される。そして、流出口５０９には、紫外線光源５１５が配されており、流出口５０９を通過する水に紫外光を浴びせることで、水の殺菌がなされる。 The cold sink 505 includes a cooling sink fin that is thermally coupled to the low temperature side of the thermoelectric device 507. The cold sink 505 cools the air flowing in by the blower 502 below the dew point and condenses the water droplets 542. Then, the water droplet 542 is output to the outside from an outlet 509 provided in the pipe diverter 508. An ultraviolet light source 515 is disposed at the outlet 509, and the water passing through the outlet 509 is exposed to ultraviolet light to sterilize the water.
　コールドシンク５０５で冷却された空気は、配管分流部５０８を通り、ヒートシンク５０６に流入する。 The air cooled by the cold sink 505 flows into the heat sink 506 through the pipe diverter 508.
　ヒートシンク５０６は、熱電装置５０７の高温側と熱結合されたヒートシンクフィンを備えている。コールドシンク５０５で冷却された空気を、ヒートシンク５０６に流入させ、ヒートシンク５０６の熱を奪うことで、熱電装置５０７の効率を高めている。 The heat sink 506 includes heat sink fins that are thermally coupled to the high temperature side of the thermoelectric device 507. The air cooled by the cold sink 505 is caused to flow into the heat sink 506, and the heat of the heat sink 506 is taken away, thereby increasing the efficiency of the thermoelectric device 507.
　水生成装置５００では、送風機５０２・５４４・５０４の動作速度を順次制御することで、コールドシンク５０５が温度を露点以下となるように制御している。 In the water generation device 500, the cold sink 505 controls the temperature to be below the dew point by sequentially controlling the operating speed of the blowers 502, 544, and 504.
　さらに、コールドシンク５０５内に設けられた紫外線電球５１８と、ヒートシンク５０６内に設けられた紫外線電球５１７とによって、コールドシンク５０５及びヒートシンク５０６の殺菌がなされる。 Further, the cold sink 505 and the heat sink 506 are sterilized by the ultraviolet light bulb 518 provided in the cold sink 505 and the ultraviolet light bulb 517 provided in the heat sink 506.
　このように、水生成装置５００では、空気から水が生成されるので、使用する場所で水を生成することができ、水を持ち運ぶ手間を削減することができる。 Thus, in the water generating device 500, water is generated from the air, so that it is possible to generate water at a place where it is used, and it is possible to reduce time and effort for carrying the water.

　〔実施の形態１〕
　（植物栽培システム１の構成）
　図１は、第１の実施の形態にかかる植物栽培システム１の構成を表す図である。 [Embodiment 1]
(Configuration of plant cultivation system 1)
FIG. 1 is a diagram illustrating a configuration of a plant cultivation system 1 according to the first embodiment.
　図１に示すように、植物栽培システム１は、冷却ファン２ａと、結露装置１０と、リザーバー２０と、送液装置３０と、植物栽培装置４０と、減圧・送風装置５０と、水分量調整部６０と、水分量記憶部６１とを備えている。 As shown in FIG. 1, the plant cultivation system 1 includes a cooling fan 2 a, a dew condensation device 10, a reservoir 20, a liquid feeding device 30, a plant cultivation device 40, a decompression / blower device 50, and a moisture amount adjustment unit. 60 and a water content storage unit 61.
　植物栽培システム１は、植物栽培装置４０で栽培されている植物４１に自動で給水し、クリーンな水と空気を供給することが可能な植物を栽培するためのシステムである。 The plant cultivation system 1 is a system for cultivating a plant capable of automatically supplying water to the plant 41 cultivated by the plant cultivation apparatus 40 and supplying clean water and air.
　結露装置（水生成装置）１０は、栽培する植物４１に供給する水を生成する植物供給用の水生成装置である。 The dew condensation device (water generation device) 10 is a plant supply water generation device that generates water to be supplied to the plant 41 to be cultivated.
　結露装置１０は、本体１１と、本体１１の下方に配され、内部に水用フィルタが配されている水用フィルタ格納部１３と、水用フィルタ格納部１３に格納された水用フィルタ透過した水を、植物４１に供給するための排水管（供給管）１４とを備えている。 The dew condensation device 10 is transmitted through a main body 11, a water filter storage unit 13 disposed below the main body 11 and having a water filter disposed therein, and a water filter stored in the water filter storage unit 13. A drain pipe (supply pipe) 14 for supplying water to the plant 41 is provided.
　本体１１は、内部に熱電素子が格納された熱電素子格納部１５と、空気用フィルタ１６と、本体底部１７とを備えている。 The main body 11 includes a thermoelectric element storage portion 15 in which a thermoelectric element is stored, an air filter 16, and a main body bottom portion 17.
　本体１１と、水用フィルタ格納部１３とは、配管１２によって接続されている。排水管１４は、一方の端部が水用フィルタ格納部１３と接続されている。そして、排水管１４は、リザーバー２０の蓋２１を貫通し、他方の端部は、リザーバー２０の内部に配されている。 The main body 11 and the water filter storage unit 13 are connected by a pipe 12. One end of the drain pipe 14 is connected to the water filter storage unit 13. The drain pipe 14 passes through the lid 21 of the reservoir 20, and the other end is disposed inside the reservoir 20.
　結露装置１０では、空気用フィルタ１６でフィルタリングされた空気によって、内部で結露を発生させる。そして、結露装置１０は、内部で発生した結露をさらに、水用フィルタ格納部１３内の水用フィルタを透過させ、当該水用フィルタを透過した水を、排水管１４を通じて、リザーバー２０に貯水させる。 In the dew condensation device 10, dew condensation is generated inside by the air filtered by the air filter 16. The dew condensation device 10 further causes the dew generated inside to pass through the water filter in the water filter storage unit 13, and stores the water that has passed through the water filter in the reservoir 20 through the drain pipe 14. .
　このため、結露装置１０によると、植物４１に供給する水としては、充分に除菌された水を植物４１に供給することができる。 For this reason, according to the dew condensation apparatus 10, as the water supplied to the plant 41, sufficiently sterilized water can be supplied to the plant 41.
　なお、結露装置１０の詳細な構成については後述する。 The detailed configuration of the dew condensation apparatus 10 will be described later.
　冷却ファン２は、温度制御部７０が備える冷却ファン駆動制御部（送風制御部）７２からの指示によってファンを回転駆動する。冷却ファン２は、ファンを回転させ、熱電素子格納部１５に風を送ることで、熱電素子格納部１５（及び内部の熱電素子）を冷やし、熱電素子格納部１５（及び内部の熱電素子）の温度調整を行うためのものである。 The cooling fan 2 rotationally drives the fan according to an instruction from a cooling fan drive control unit (blower control unit) 72 provided in the temperature control unit 70. The cooling fan 2 rotates the fan and sends air to the thermoelectric element storage unit 15 to cool the thermoelectric element storage unit 15 (and the internal thermoelectric element), and the thermoelectric element storage unit 15 (and the internal thermoelectric element). This is for adjusting the temperature.
　温度制御部７０は、結露装置１０に配されている各センサからの出力に基づいて結露装置１０が備える熱電素子の温度を、外気の露点温度以下となるように、制御するものである。温度制御部７０は、露点温度算出部７１と、冷却ファン駆動制御部７２と、温度管理部７３とを備えている。 The temperature control unit 70 controls the temperature of the thermoelectric element included in the dew condensation device 10 based on the output from each sensor disposed in the dew condensation device 10 so as to be equal to or lower than the dew point temperature of the outside air. The temperature control unit 70 includes a dew point temperature calculation unit 71, a cooling fan drive control unit 72, and a temperature management unit 73.
　温度制御部７０は、高温側温度計６ａ（図２参照）から出力されてきた高温側の熱電素子５ａ（図２参照）の温度Ｔａ、低温側温度計６ｂ（図２参照）から出力されてきた低温側の熱電素子５ｂの温度Ｔｌ、温湿度計６ｃ（図２参照）から出力されてきた結露装置１０の外部の空気の湿度Ｈａ及び結露装置１０の外部の空気の温度Ｔａを取得する。 The temperature control unit 70 outputs the temperature Ta of the high temperature side thermoelectric element 5a (see FIG. 2) output from the high temperature side thermometer 6a (see FIG. 2) and the low temperature side thermometer 6b (see FIG. 2). The temperature Tl of the thermoelectric element 5b on the low temperature side, the humidity Ha of the air outside the dew condensation device 10 output from the temperature / humidity meter 6c (see FIG. 2), and the temperature Ta of the air outside the dew condensation device 10 are acquired.
　また、温度制御部７０には、温度Ｔｌを、本体１１の内部の露点温度Ｔｄより確実に低い温度に維持できるように、温度Ｔｌの目標設定温度Ｔｔ（Ｔｔ＜Ｔｄ）の設定方法（演算方法）を、予め記憶しておくことが好ましい。目標設定温度Ｔｔは、結露温度算出部７１が算出した結露温度Ｔｄから演算で値を算出し、設定できるように、設定方法を温度制御部７０に記憶しておく。 In addition, the temperature control unit 70 sets the target setting temperature Tt (Tt <Td) of the temperature Tl so that the temperature Tl can be reliably maintained at a temperature lower than the dew point temperature Td inside the main body 11 (calculation method). ) Is preferably stored in advance. The target setting temperature Tt is stored in the temperature control unit 70 so that a value can be calculated and set from the condensation temperature Td calculated by the condensation temperature calculation unit 71.
　結露温度算出部７１は、温度制御部７０が取得した温度Ｔａ及び湿度Ｈａから、本体１１の内部の露点温度Ｔｄを算出する。さらに、結露温度算出部７１は、予め温度制御部７０に記憶されている目標設定温度Ｔｔの設定方法から、算出した結露温度Ｔｄに基づいて目標設定温度Ｔｔを設定する。 The dew condensation temperature calculation unit 71 calculates the dew point temperature Td inside the main body 11 from the temperature Ta and the humidity Ha acquired by the temperature control unit 70. Further, the dew condensation temperature calculation unit 71 sets the target set temperature Tt based on the calculated dew condensation temperature Td from the setting method of the target set temperature Tt stored in the temperature control unit 70 in advance.
　冷却ファン駆動制御部７２は、冷却ファン２の駆動を制御するものである。冷却ファン駆動制御部７２は、露点温度算出部７１が算出した露点温度Ｔｄと、温度制御部７０が取得した低温側の熱電素子５ｂの温度Ｔｌとを比較する。そして、冷却ファン駆動制御部７２は、温度Ｔｌが露点温度Ｔｄより低くなるように、冷却ファン２ａの回転数や、冷却ファン２ａの駆動のオン、オフ時間をなど制御する。 The cooling fan drive control unit 72 controls the driving of the cooling fan 2. The cooling fan drive control unit 72 compares the dew point temperature Td calculated by the dew point temperature calculation unit 71 with the temperature Tl of the low-temperature-side thermoelectric element 5 b acquired by the temperature control unit 70. Then, the cooling fan drive control unit 72 controls the rotation speed of the cooling fan 2a, the on / off time of driving of the cooling fan 2a, and the like so that the temperature Tl becomes lower than the dew point temperature Td.
　または、目標設定温度Ｔｔが設定されているときは、冷却ファン駆動制御部７２は、露点温度算出部７１が設定した目標設定温度Ｔｔと、温度制御部７０が取得した低温側の熱電素子５ｂの温度Ｔｌとを比較する。そして、冷却ファン駆動制御部７２は、温度Ｔｌが目標設定温度Ｔｔより低くなるように、冷却ファン２ａの回転数や、冷却ファン２ａの駆動のオン、オフ時間をなど制御する。 Alternatively, when the target set temperature Tt is set, the cooling fan drive control unit 72 sets the target set temperature Tt set by the dew point temperature calculating unit 71 and the low temperature side thermoelectric element 5b acquired by the temperature control unit 70. Compare with temperature Tl. Then, the cooling fan drive control unit 72 controls the rotation speed of the cooling fan 2a, the on / off time of driving of the cooling fan 2a, and the like so that the temperature Tl becomes lower than the target set temperature Tt.
　温度管理部７３は、温度制御部７０が取得した温度Ｔｈや、温度Ｔｈと温度Ｔｌとの差分である温度差ΔＴが異常な値（予め設定された限界値を越える値）になっていないかを監視する。温度管理部７３は、温度Ｔｈや、温度差ΔＴが異常な値となっていると判定すると、冷却ファン駆動制御部７２に、冷却ファン２の駆動を強制的に停止させる。 Whether the temperature management unit 73 has a temperature Th acquired by the temperature control unit 70 or a temperature difference ΔT that is a difference between the temperature Th and the temperature Tl is an abnormal value (a value exceeding a preset limit value). To monitor. If the temperature management unit 73 determines that the temperature Th or the temperature difference ΔT is an abnormal value, the temperature management unit 73 causes the cooling fan drive control unit 72 to forcibly stop driving the cooling fan 2.
　冷却ファン２は、冷却ファン駆動制御部７２からの指示によって、ファンの回転のオン（ＯＮ）、オフ（ＯＦＦ）の制御や、回転数の制御がなされる。このように、冷却ファン２の回転数を制御することで、熱電素子格納部１５及び内部の熱電素子の温度調整を行うことができ、熱電素子格納部１５及び上記熱電素子を、外気の環境に適した温度に設定することができる。 The cooling fan 2 is controlled to turn on (ON) or off (OFF) the fan and control the number of rotations according to an instruction from the cooling fan drive control unit 72. Thus, by controlling the rotation speed of the cooling fan 2, the temperature of the thermoelectric element storage unit 15 and the internal thermoelectric element can be adjusted, and the thermoelectric element storage unit 15 and the thermoelectric element are brought into the environment of the outside air. A suitable temperature can be set.
　冷却ファン２は、冷却ファン２から出力された風が、熱電素子格納部１５の上面に触れて、冷却ファン２が配されている側とは逆側に送られるように配されている。これにより、冷却ファン２が送風する風により、効率よく熱電素子格納部１５を冷却することができる。 The cooling fan 2 is arranged so that the wind output from the cooling fan 2 touches the upper surface of the thermoelectric element storage unit 15 and is sent to the side opposite to the side where the cooling fan 2 is arranged. Thereby, the thermoelectric element storage part 15 can be efficiently cooled by the wind blown by the cooling fan 2.
　リザーバー２０は、排水管１４を通って流入してくる水を貯水するためのものである。 The reservoir 20 is for storing water flowing in through the drain pipe 14.
　リザーバー２０は、結露装置１０の下方に配されている。リザーバー２０は、上方に設けられた開口に蓋２１が配されていることで密閉されている。 The reservoir 20 is disposed below the dew condensation device 10. The reservoir 20 is hermetically sealed by providing a lid 21 in an opening provided above.
　送液装置３０は、リザーバー２０に貯水された水を、植物栽培装置４０で栽培されている植物４１に供給するためのものである。 The liquid feeding device 30 is for supplying the water stored in the reservoir 20 to the plant 41 cultivated by the plant cultivation device 40.
　送液装置３０は、流入管３１と、送液装置本体３２と、排水管３３とを備えている。流入管３１の一方の端部は、リザーバー２０の底部近傍で、リザーバー２０と接続されており、他方は、送液装置本体３２と接続されている。 The liquid feeding device 30 includes an inflow pipe 31, a liquid feeding device main body 32, and a drain pipe 33. One end of the inflow pipe 31 is connected to the reservoir 20 in the vicinity of the bottom of the reservoir 20, and the other is connected to the liquid feeder main body 32.
　排水管３３の一方の端部は、送液装置本体３２と接続されており、他方の端部は、植物栽培装置４０と接続されている。 One end of the drain pipe 33 is connected to the liquid feeding device main body 32, and the other end is connected to the plant cultivation device 40.
　送液装置本体３２は、リザーバー２０に貯水されている水を、流入管３１から流入させ、排水管３３を通って植物栽培装置４０に送るポンプである。 The liquid feeder main body 32 is a pump that causes the water stored in the reservoir 20 to flow from the inflow pipe 31 and send it to the plant cultivation apparatus 40 through the drain pipe 33.
　植物栽培装置４０は、植物４１を栽培するためのものである。植物栽培装置４０は、容器４２と、容器４２内に配され、植物４１を栽培する培地である土４３と、土４３の水分量を測定する土壌水分センサ（培地水分測定装置）４４と、土で栽培されている植物４１とを備えている。また、土４３の乾燥を防止するために、蓋４５が配されており、この蓋４５に設けられた開口部分に植物４１と、土壌水分センサ４４とが配されている。 The plant cultivation device 40 is for cultivating the plant 41. The plant cultivation device 40 is arranged in a container 42, a soil 43 that is a medium for growing the plant 41, a soil moisture sensor (medium moisture measuring device) 44 that measures the moisture content of the soil 43, and soil. And a plant 41 cultivated in Japan. Further, in order to prevent the soil 43 from drying, a lid 45 is disposed, and a plant 41 and a soil moisture sensor 44 are disposed in an opening provided in the lid 45.
　土壌水分センサ４４は、土４３の導電率を測定することで、土４３の水分量を測定するものである。土壌水分センサ４４は、一般的に使用されているものを用いることができる。 The soil moisture sensor 44 measures the moisture content of the soil 43 by measuring the conductivity of the soil 43. As the soil moisture sensor 44, a commonly used one can be used.
　減圧・送風装置（送風装置）５０は、リザーバー２０内を減圧することで、排水管１４を通じて、結露装置１０の本体１１内を減圧するものである。 The decompression / blower device (blower device) 50 decompresses the inside of the main body 11 of the dew condensation device 10 through the drain pipe 14 by decompressing the inside of the reservoir 20.
　減圧・送風装置（送風装置）５０により、結露装置１０の本体１１内の気圧は、大気圧より低くなるように調整されている。 The pressure in the main body 11 of the dew condensation device 10 is adjusted to be lower than the atmospheric pressure by the decompression / blower device (blower device) 50.
　このように、減圧・送風装置（送風装置）５０により、結露装置１０の本体１１内が減圧されることで、空気用フィルタ１６を通して、結露装置１０の本体１１内に空気が流入する。 In this way, the pressure in the main body 11 of the dew condensation device 10 is depressurized by the decompression / blower device (blower device) 50, so that air flows into the main body 11 of the dew condensation device 10 through the air filter 16.
　減圧・送風装置５０は、流入管５１と、減圧・送風装置本体５２と、送風管５３とを備えている。 The decompression / blower device 50 includes an inflow pipe 51, a decompression / blower apparatus body 52, and a blower pipe 53.
　流入管５１の一方の端部は、リザーバー２０の内部であり、リザーバー２０内に貯水されている水と離間するように配されている。流入管５１は、蓋２１を貫通し、流入管５１の他方の端部は減圧・送風装置本体５２と接続されている。 One end of the inflow pipe 51 is inside the reservoir 20 and is arranged so as to be separated from the water stored in the reservoir 20. The inflow pipe 51 passes through the lid 21, and the other end of the inflow pipe 51 is connected to the decompression / blower device main body 52.
　送風管５３の一方の端部は、減圧・送風装置本体５２と接続されており、他方の端部は、送風管５３を通って送られてくる風が、植物４１に送風されるように、植物４１に向かって配されている。 One end of the blower pipe 53 is connected to the decompression / blower device main body 52, and the other end is so that the wind sent through the blower pipe 53 is blown to the plant 41. It is arranged toward the plant 41.
　減圧・送風装置本体５２は、リザーバー２０内の空気を、流入管５１から流入させ、送風管５３を通って、植物４１に送風するポンプである。 The decompression / blower device main body 52 is a pump that causes the air in the reservoir 20 to flow from the inflow pipe 51 and blows the air to the plant 41 through the blower pipe 53.
　リザーバー２０内の空気は、空気用フィルタ１６を通ってきた空気なので、除菌されたきれいな空気である。このような除菌された空気を、植物４１に、直接、送風することで、植物４１の周囲の空気を除菌されたきれいな空気とすることができる。 The air in the reservoir 20 is clean air that has been sterilized because it has passed through the air filter 16. By blowing such sterilized air directly to the plant 41, the air around the plant 41 can be made clean and sterilized air.
　減圧・送風装置本体５２は、約０．３～０．８ｍ／ｓ程度の除菌された風を、植物４１に送風する。 The decompression / blower main body 52 blows the sterilized wind of about 0.3 to 0.8 m / s to the plant 41.
　このように、約０．３～０．８ｍ／ｓ程度の適度な送風は、植物４１のガス交換を助け、植物４１の成長を促進することができる。 As described above, moderate air blowing of about 0.3 to 0.8 m / s can help the plant 41 to exchange gas and promote the growth of the plant 41.
　水分量記憶部６１には、栽培する植物４１に応じて、土４３の好ましい水分量が記憶されている。 The water content storage unit 61 stores a preferable water content of the soil 43 according to the plant 41 to be cultivated.
　水分量調整部（水分量比較手段）６０は、ＣＰＵ、ハードディスク、メモリなどを備えているコンピュータである。なお、水分量記憶部６１は、水分量調整部６０の内部に配されていてもよいし、水分量調整部６０の外部に配されていてもよい。 The moisture amount adjustment unit (moisture amount comparison means) 60 is a computer including a CPU, a hard disk, a memory, and the like. The moisture amount storage unit 61 may be disposed inside the moisture amount adjustment unit 60 or may be disposed outside the moisture amount adjustment unit 60.
　水分量調整部（水分量比較手段）６０は、土壌水分センサ４４から、土壌水分センサ４４が測定した土４３の水分量を取得する。そして、水分量調整部６０は、水分量記憶部６１を参照し、土壌水分センサ４４から取得した土４３の水分量と、水分量記憶部６１に記憶されている水分量とを比較する。 The moisture content adjustment unit (moisture content comparison means) 60 acquires the moisture content of the soil 43 measured by the soil moisture sensor 44 from the soil moisture sensor 44. Then, the moisture amount adjustment unit 60 refers to the moisture amount storage unit 61 and compares the moisture amount of the soil 43 acquired from the soil moisture sensor 44 with the moisture amount stored in the moisture amount storage unit 61.
　そして、水分量調整部６０は、土壌水分センサ４４が測定した土４３の水分量は、予め設定された水分量より少ないと判定すると、当該判定結果を、送液装置３０に出力し、送液装置３０に、リザーバー２０に貯水された水を、植物栽培装置４０の土４３に供給させる。 And if the moisture content adjustment part 60 determines that the moisture content of the soil 43 measured by the soil moisture sensor 44 is less than a preset moisture content, the determination result is output to the fluid delivery device 30 to deliver the fluid. The apparatus 30 causes the water stored in the reservoir 20 to be supplied to the soil 43 of the plant cultivation apparatus 40.
　これにより、土４３が水不足となり、栽培されている植物４１が枯れることを防止することができる。 This can prevent the soil 43 from running out of water and the cultivated plant 41 from withering.
　一方、水分量調整部６０は、土壌水分センサ４４が測定した土４３の水分量は、予め設定された水分量以上であると判定すると、当該判定結果を、送液装置３０に出力し、送液装置３０が、リザーバー２０に貯水された水を、植物栽培装置４０の土４３に供給している場合は、水の供給を停止させる。 On the other hand, if the water content adjusting unit 60 determines that the water content of the soil 43 measured by the soil water sensor 44 is equal to or greater than a preset water content, the determination result is output to the liquid delivery device 30 and sent. When the liquid device 30 supplies the water stored in the reservoir 20 to the soil 43 of the plant cultivation device 40, the supply of water is stopped.
　これにより、土４３への水の供給が過剰となり、栽培されている植物４１が枯れることを防止することができる。 This can prevent the water supply to the soil 43 from becoming excessive and the plant 41 being cultivated from withering.
　このようにして、水分量調整部６０は、これをあらかじめ設定した水分量と、土４３の水分量とを比較して、送液装置３０のＯＮ／ＯＦＦを制御したり、送液装置３０の水分の供給速度を増加させたり、減速させたりする。 In this way, the moisture amount adjusting unit 60 compares the moisture amount set in advance with the moisture amount of the soil 43 to control the ON / OFF of the liquid feeding device 30 or the liquid feeding device 30. Increase or slow the moisture supply rate.
　このため、植物４１の根圏の水分量を自動で管理することができ、土４３を、栽培する植物４１に適した水分量に管理することができる。なお、水分量調整部６０が行う処理の流れは後述する。 For this reason, the water content in the rhizosphere of the plant 41 can be automatically managed, and the soil 43 can be managed in a water content suitable for the plant 41 to be cultivated. The flow of processing performed by the moisture amount adjusting unit 60 will be described later.
　このように植物栽培システム１は、結露装置１０と、結露装置１０の排水管１４を通って流入してくる水を貯水するリザーバー２０と、植物４１を栽培する植物栽培装置４０と、リザーバー２０に貯水された水を、植物４１に供給する送液装置３０とを備えている。 As described above, the plant cultivation system 1 includes the dew condensation device 10, the reservoir 20 that stores water flowing in through the drain pipe 14 of the dew condensation device 10, the plant cultivation device 40 that grows the plant 41, and the reservoir 20. And a liquid feeding device 30 that supplies the stored water to the plant 41.
　これにより、結露装置１０で生成された水は、排水管１４を通ってリザーバー２０に貯水される。そして、送液装置３０によって、リザーバー２０に貯水された水は、植物栽培装置４０で栽培されている植物４１に供給される。 Thus, the water generated by the dew condensation device 10 is stored in the reservoir 20 through the drain pipe 14. Then, the water stored in the reservoir 20 is supplied to the plant 41 cultivated by the plant cultivation device 40 by the liquid feeding device 30.
　ここで、土４３の表面を見ただけでは、土４３が乾燥しているか否かを判断することはわかりづらく、特に夏場は、土４３の水分の蒸発が早いので、土４３を水不足にしてしまう場合がある。 Here, it is difficult to determine whether or not the soil 43 is dry only by looking at the surface of the soil 43. Especially in the summer, the moisture of the soil 43 evaporates quickly. May end up.
　そこで、植物栽培システム１では、上述したように、土壌水分センサ４４で測定した水分量が、予め設定した水分量となっているかを判断して、土４３の水分量を調整するので、土４３の環境を、植物４１の種類に適した環境に維持することができる。 Therefore, in the plant cultivation system 1, as described above, it is determined whether the moisture amount measured by the soil moisture sensor 44 is a preset moisture amount, and the moisture amount of the soil 43 is adjusted. Can be maintained in an environment suitable for the type of plant 41.
　このようにして、植物栽培システム１では、結露装置１０で生成された水は、植物栽培装置４０で栽培されている植物４１に自動で供給することができるので、植物４１に水を供給するために水を持ち運ぶ手間を省くことができる。 In this way, in the plant cultivation system 1, the water generated by the dew condensation device 10 can be automatically supplied to the plant 41 cultivated by the plant cultivation device 40, so that water is supplied to the plant 41. This saves you the trouble of carrying water.
　（結露装置の構成）
　次に、図２を用いて、結露装置１０の詳細な構成について説明する。 (Condensation device configuration)
Next, the detailed structure of the dew condensation apparatus 10 is demonstrated using FIG.
　図２は、結露装置１０の構成を表す断面図である。 FIG. 2 is a cross-sectional view showing the configuration of the dew condensation apparatus 10.
　結露装置１０の本体１１は、上方から下方にかけて、順に配された、熱電素子格納部１５（本体上部）と、空気用フィルタ１６と、本体底部１７とを備えている。 The main body 11 of the dew condensation apparatus 10 includes a thermoelectric element storage portion 15 (main body upper portion), an air filter 16 and a main body bottom portion 17 which are arranged in order from the upper side to the lower side.
　熱電素子格納部１５内には、熱電素子５が配されている。熱電素子５は、相対的に上方に配されている高温側の熱電素子５ａと、高温側の熱電素子５ａの下方に配されている低温側の熱電素子５ｂとからなる。 A thermoelectric element 5 is arranged in the thermoelectric element storage unit 15. The thermoelectric element 5 includes a high-temperature-side thermoelectric element 5a disposed relatively upward and a low-temperature-side thermoelectric element 5b disposed below the high-temperature-side thermoelectric element 5a.
　また、結露装置１０は、高温側温度計６ａと、低温側温度計６ｂと、温湿度計６ｃとを備えている。 Further, the dew condensation apparatus 10 includes a high temperature side thermometer 6a, a low temperature side thermometer 6b, and a temperature and humidity meter 6c.
　高温側温度計６ａは、熱電素子５ａの温度を測定するための温度計である。高温側温度計６ａは、熱電素子５ａの近傍であり、熱電素子格納部１５の上面に配されている。高温側温度計６ａは、高温側の熱電素子５ａの温度Ｔｈを測定し、当該測定した高温側の熱電素子５ａの温度Ｔｈを温度制御部７０に出力する。 The high temperature side thermometer 6a is a thermometer for measuring the temperature of the thermoelectric element 5a. The high temperature side thermometer 6 a is arranged in the vicinity of the thermoelectric element 5 a and on the upper surface of the thermoelectric element storage unit 15. The high temperature side thermometer 6 a measures the temperature Th of the high temperature side thermoelectric element 5 a and outputs the measured temperature Th of the high temperature side thermoelectric element 5 a to the temperature control unit 70.
　低温側温度計６ｂは熱電素子５ｂの温度を測定するための温度計である。低温側温度計６ｂは、熱電素子５ｂの近傍であり、熱電素子格納部１５の下面に配されている。低温側温度計６ｂは、低温側の熱電素子５ｂの温度Ｔｌを測定し、当該測定した低温側の熱電素子５ｂの温度Ｔｌを温度制御部７０に出力する。 The low temperature side thermometer 6b is a thermometer for measuring the temperature of the thermoelectric element 5b. The low temperature side thermometer 6 b is disposed in the vicinity of the thermoelectric element 5 b and on the lower surface of the thermoelectric element storage unit 15. The low temperature side thermometer 6 b measures the temperature Tl of the low temperature side thermoelectric element 5 b, and outputs the measured temperature Tl of the low temperature side thermoelectric element 5 b to the temperature control unit 70.
　温湿度計６ｃは空気用フィルタ１６を介して本体１１の内部に流入する空気の温湿度を測定するための温湿度計である。温湿度計６ｃは、空気用フィルタ１６の近傍であり、熱電素子格納部１５の側面に配されている。温湿度計６ｃは、結露装置１０の外部の空気の湿度Ｈａ、結露装置１０の外部の空気の温度Ｔａを測定し、当該測定した結露装置１０の外部の空気の湿度Ｈａ、結露装置１０の外部の空気の温度Ｔａを温度制御部７０に出力する。 The temperature / humidity meter 6 c is a temperature / humidity meter for measuring the temperature / humidity of the air flowing into the main body 11 through the air filter 16. The thermohygrometer 6 c is located near the air filter 16 and is disposed on the side surface of the thermoelectric element storage unit 15. The temperature / humidity meter 6c measures the humidity Ha of the air outside the dew condensation device 10 and the temperature Ta of the air outside the dew condensation device 10 and measures the measured air humidity Ha outside the dew condensation device 10 and the outside of the dew condensation device 10. The air temperature Ta is output to the temperature control unit 70.
　高温側温度計６ａ、低温側温度計６ｂ、及び温湿度計６ｃと、温度制御部７０とは、有線又は無線により、高温側温度計６ａ、低温側温度計６ｂ、及び温湿度計６ｃのそれぞれが測定した温度、湿度を送信可能に接続されている。 The high temperature side thermometer 6a, the low temperature side thermometer 6b, the temperature / humidity meter 6c, and the temperature controller 70 are wired or wirelessly connected to the high temperature side thermometer 6a, the low temperature side thermometer 6b, and the temperature / humidity meter 6c, respectively. Is connected so that the measured temperature and humidity can be transmitted.
　冷却ファン２から送風されてきた空気Ａは、熱電素子格納部１５の上面を通過する。このようにして、冷却ファン２から送風されてきた空気Ａによって、熱電素子格納部１５及び熱電素子５が冷やされる。このようにして、熱電素子格納部１５及び熱電素子５の温度調整がなされる。すなわち、本実施の形態に係る植物栽培システム１では、冷却ファン２は、水平方向に空気Ａを送風する。 The air A blown from the cooling fan 2 passes through the upper surface of the thermoelectric element storage unit 15. In this manner, the thermoelectric element storage unit 15 and the thermoelectric element 5 are cooled by the air A blown from the cooling fan 2. In this manner, the temperature of the thermoelectric element storage unit 15 and the thermoelectric element 5 is adjusted. That is, in the plant cultivation system 1 according to the present embodiment, the cooling fan 2 blows the air A in the horizontal direction.
　本体内部１１ａは、熱電素子格納部１５と、空気用フィルタ１６と、本体底部１７とによって構成されている空間である。また、本体内部１１ａの上面は、熱電素子格納部１５の底面である。 The main body interior 11 a is a space constituted by the thermoelectric element storage portion 15, the air filter 16, and the main body bottom portion 17. The upper surface of the main body interior 11 a is the bottom surface of the thermoelectric element storage unit 15.
　高温側の熱電素子５ａと、低温側の熱電素子５ｂとによって、熱電素子格納部１５に温度差が設けられる。これにより、低温側の熱電素子５ｂの近傍の熱電素子格納部１５の空気、すなわち、本体内部１１ａの空気中の水分が結露する。このようにして、本体内部１１ａの上面に結露が付着する。 A temperature difference is provided in the thermoelectric element storage section 15 by the thermoelectric element 5a on the high temperature side and the thermoelectric element 5b on the low temperature side. As a result, moisture in the air in the thermoelectric element storage 15 near the thermoelectric element 5b on the low temperature side, that is, moisture in the air inside the main body 11a is condensed. In this way, condensation adheres to the upper surface of the main body inside 11a.
　空気用フィルタ１６は、本体内部１１ａに流入する空気用のフィルタである。空気用フィルタ１６として、例えば、ＨＥＰＡフィルタ（High Efficiency Particulate Air Filter）を用いることができる。 The air filter 16 is a filter for air flowing into the main body inside 11a. As the air filter 16, for example, a HEPA filter (High （Efficiency ParticulateicAir Filter) can be used.
　本体内部１１ａは、上述したように減圧されている。すなわち、本体内部１１ａの気圧は、大気圧より低い。 The interior 11a of the main body is decompressed as described above. That is, the atmospheric pressure inside the main body 11a is lower than the atmospheric pressure.
　このため、本体１１の外側の空気は、空気用フィルタ１６を通って、本体内部１１ａに流入する。このように、本体内部１１ａに流入する空気は、空気用フィルタ１６を通っているので、本体内部１１ａに、バクテリア、カビ、藻類が混入することを防止することができる。 For this reason, the air outside the main body 11 flows into the main body interior 11a through the air filter 16. Thus, since the air flowing into the main body interior 11a passes through the air filter 16, it is possible to prevent bacteria, fungi, and algae from entering the main body interior 11a.
　本体底部１７には開口１７ａが設けられている。この本体底部１７の開口１７ａに配管１２が接続されている。そして、本体底部１７は、本体内部１１ａで発生した結露３を開口１７ａに導くように傾斜している。 The main body bottom 17 is provided with an opening 17a. The pipe 12 is connected to the opening 17 a of the main body bottom 17. And the main body bottom part 17 inclines so that the dew condensation 3 which generate | occur | produced in the main body inside 11a may be guide | induced to the opening 17a.
　上述したように、本体１１は、熱電素子格納部１５と、空気用フィルタ１６と、本体底部１７とが、上方から下方に向けて順に配されている。 As described above, in the main body 11, the thermoelectric element storage portion 15, the air filter 16, and the main body bottom portion 17 are arranged in order from the top to the bottom.
　換言すると、熱電素子格納部１５と、本体底部１７との間は、空気用フィルタ１６が配されている。このため、熱電素子格納部１５と、本体底部１７とは離間して配されることになるので、本体内部１１ａの体積が大きくなり、空気用フィルタ１６を通って、本体内部１１ａに多くの空気を流入させることができる。このため、本体内部１１ａで効率よく結露３を発生させることができる。 In other words, the air filter 16 is disposed between the thermoelectric element storage portion 15 and the main body bottom portion 17. For this reason, since the thermoelectric element storage portion 15 and the main body bottom portion 17 are arranged apart from each other, the volume of the main body interior 11a increases, and a large amount of air passes through the air filter 16 to the main body interior 11a. Can be introduced. For this reason, the dew condensation 3 can be efficiently generated in the main body inside 11a.
　さらに、本体底部１７は、熱電素子格納部１５の下方に配されているので、熱電素子格納部１５の表面（下面）に付着した結露３は重力により、本体底部１７に落下する。そして、本体底部１７に落下した結露３は、傾斜した本体底部１７伝って開口１７ａに集められ、回収される。このように、本体１１は、簡単な構成で、熱電素子格納部１５に付着した結露３を回収することができる。 Furthermore, since the main body bottom portion 17 is disposed below the thermoelectric element storage portion 15, the dew condensation 3 adhering to the surface (lower surface) of the thermoelectric element storage portion 15 falls to the main body bottom portion 17 due to gravity. The dew condensation 3 that has dropped to the main body bottom 17 is collected in the opening 17a through the inclined main body bottom 17 and collected. Thus, the main body 11 can collect the dew condensation 3 attached to the thermoelectric element storage unit 15 with a simple configuration.
　配管１２には、シリコンチューブ等のチューブ連結管１２ａが設けられている。 The pipe 12 is provided with a tube connecting pipe 12a such as a silicon tube.
　水用フィルタ格納部１３内には、水用フィルタ７が配されている。水用フィルタ格納部１３内は、上述した減圧・送風装置（送風装置）５０により減圧されている。すなわち、水用フィルタ格納部１３内は、水用フィルタ７の上方に比べ、水用フィルタ７の下方の方が気圧が低い。このため、結露装置１０の本体内部１１ａから流れてきた結露３は、水用フィルタ７を通過する。 A water filter 7 is disposed in the water filter storage unit 13. The inside of the water filter storage unit 13 is decompressed by the decompression / blower device (blower device) 50 described above. That is, in the water filter storage unit 13, the air pressure is lower in the lower part of the water filter 7 than in the upper part of the water filter 7. For this reason, the dew condensation 3 that has flowed from the main body inside 11 a of the dew condensation device 10 passes through the water filter 7.
　水用フィルタ７は、例えば、芳香族ポリアミドなどから構成されるメンブレンフィルターである。 The water filter 7 is a membrane filter made of, for example, aromatic polyamide.
　水用フィルタ７の孔径は、空気用フィルタ１６の孔径より小さい。一例として、水用フィルタ７の孔径は５μｍ程度であり、空気用フィルタ１６の孔径は２０～３０μｍ程度である。 The hole diameter of the water filter 7 is smaller than the hole diameter of the air filter 16. As an example, the hole diameter of the water filter 7 is about 5 μm, and the hole diameter of the air filter 16 is about 20 to 30 μm.
　これにより、結露装置１０の本体内部１１ａの局所的な温度変化でできた氷や、空気用フィルタ１６で濾過しきれなかった粒子などを取り除き、水用フィルタ７自体の寿命を延ばすことができる。さらに、結露３のコンタミネーション（以下、コンタミと称する）防止の信頼性を向上することができる。 This makes it possible to remove the ice formed by the local temperature change in the main body inside 11a of the dew condensation device 10 and the particles that could not be filtered by the air filter 16 and extend the life of the water filter 7 itself. Furthermore, the reliability of preventing contamination 3 (hereinafter referred to as contamination) of condensation 3 can be improved.
　なお、水用フィルタ７は、複数設置することで、多段式にしてもよい。これにより、さらに、結露３のコンタミ防止の信頼性を向上することができる。 It should be noted that a plurality of water filters 7 may be installed in a multistage manner. Thereby, the reliability of contamination prevention of condensation 3 can be further improved.
　水用フィルタ格納部１３の下面には、排水管１４が接続されている。そして、排水管１４のうち、水用フィルタ格納部１３と接続されている一方の端部の近傍には、シリコンチューブ等連結管１４ａが配されている。 A drain pipe 14 is connected to the lower surface of the water filter storage unit 13. In the vicinity of one end of the drain pipe 14 connected to the water filter storage section 13, a connecting pipe 14 a such as a silicon tube is disposed.
　このように、水用フィルタ格納部１３の上下にそれぞれ連結管１２ａと、連結管１４ａとを設けることで、水用フィルタ格納部１３を取り外し可能な構成としている。水用フィルタ７は、上述したように孔径が空気用フィルタ１６より小さく、目詰まりがしやすい。このため、水用フィルタ格納部１３の上下に連結管１２ａ・１４ａを設けることで、水用フィルタ７を交換しやすい構成としている。 Thus, by providing the connecting pipe 12a and the connecting pipe 14a above and below the water filter storage section 13, respectively, the water filter storage section 13 can be removed. As described above, the water filter 7 has a smaller hole diameter than the air filter 16 and is easily clogged. For this reason, it is set as the structure which is easy to replace | exchange the water filter 7 by providing connection pipe 12a * 14a on the upper and lower sides of the water filter storage part 13. FIG.
　また、上述したように、本体内部１１ａの空気は、空気用フィルタ１６でフィルタリング、すなわち、除菌されたきれいな空気なので、本体内部１１ａで発生した結露３も、バクテリア、カビや藻類の胞子等が除菌されたきれいなものである。 In addition, as described above, the air inside the main body 11a is clean air that has been filtered by the air filter 16, that is, sterilized, so that the condensation 3 generated inside the main body 11a is also caused by bacteria, mold, algae spores, and the like. It is clean and sterilized.
　このように、本体１１の下方に、水用フィルタ７が配されているので、本体底部１７の開口１７ａに導かれた結露３は、重力により本体底部１７の開口１７ａを流れ、水用フィルタ７を透過する。これにより、さらに、本体内部１１ａで発生した結露３のバクテリア、カビや藻類の胞子等が除菌される。 Thus, since the water filter 7 is arranged below the main body 11, the dew condensation 3 guided to the opening 17 a of the main body bottom portion 17 flows through the opening 17 a of the main body bottom portion 17 by gravity, and the water filter 7. Transparent. Thereby, bacteria of dew condensation 3, mold, algae spores and the like generated in the inside 11a of the main body are further sterilized.
　そして、水用フィルタ７を透過した、結露３は、排水管１４を流れ、植物４１に供給される。このようにして、植物４１に供給する水として、充分に除菌された水を植物４１に供給することができる。 Then, the dew condensation 3 that has passed through the water filter 7 flows through the drain pipe 14 and is supplied to the plant 41. In this way, sufficiently sterilized water can be supplied to the plant 41 as the water to be supplied to the plant 41.
　上述した特許文献１の水生成装置１００では、飲み水を生成しているので、紫外線により、生成した水や、コールドシンク１０５、ヒートシンク１０６を除菌する必要があり、装置が大型し、複雑化する。 In the water generating apparatus 100 of Patent Document 1 described above, since drinking water is generated, it is necessary to sterilize the generated water, the cold sink 105, and the heat sink 106 with ultraviolet rays, and the apparatus becomes large and complicated. To do.
　また、特許文献１の水生成装置５００では、投入するエネルギーに対し、得られる水の量が少なく、水資源が豊富な国では利点が見出し難い。 Also, in the water generating device 500 of Patent Document 1, it is difficult to find an advantage in a country where the amount of water obtained is small relative to the input energy and the water resources are abundant.
　一方、結露装置１０によると、上述したように、簡単な構成で、植物４１に供給する水を生成することができる。また、結露装置１０は、給水管理の手間を軽減し、利便性が高い。 On the other hand, according to the dew condensation apparatus 10, the water supplied to the plant 41 can be generated with a simple configuration as described above. Moreover, the dew condensation apparatus 10 reduces the labor of water supply management, and is highly convenient.
　このため、特に、家庭で、手軽に植物４１を栽培することができる。 Therefore, the plant 41 can be easily cultivated particularly at home.
　さらに、結露装置１０は、熱電素子５を利用して結露３を発生させている。このように、熱電素子５を利用することで、例えば、コンプレッサーなどを用いる冷却機器に比べ小型化・軽量化が可能である。さらに、例えば、デシカント（吸着剤）を利用して、結露を収集する機器と比べて、水の回収が容易で、不純物混入のリスクが小さい。 Furthermore, the dew condensation device 10 generates dew condensation 3 using the thermoelectric element 5. Thus, by using the thermoelectric element 5, for example, it is possible to reduce the size and weight compared to a cooling device using a compressor or the like. Furthermore, for example, compared to a device that collects dew condensation using a desiccant (adsorbent), water can be easily recovered, and the risk of contamination is small.
　（温度制御部７０の動作説明）
　次に、図１～図３を用いて温度制御部７０の処理の流れについて説明する。図３は、植物栽培システム１の温度制御部７０の処理の流れを説明する図である。 (Description of operation of temperature controller 70)
Next, a processing flow of the temperature control unit 70 will be described with reference to FIGS. FIG. 3 is a diagram for explaining a processing flow of the temperature control unit 70 of the plant cultivation system 1.
　温度制御部７０は、露点温度算出部７１と、冷却ファン駆動制御部７２と、温度管理部７３とを備えている。 The temperature control unit 70 includes a dew point temperature calculation unit 71, a cooling fan drive control unit 72, and a temperature management unit 73.
　温度制御部７０は、高温側温度計６ａから出力されてきた高温側の熱電素子５ａの温度Ｔｈ、低温側温度計６ｂから出力されてきた低温側の熱電素子５ｂの温度Ｔｌ、温湿度計６ｃから出力されてきた結露装置１０の外部の空気の湿度Ｈａ、結露装置１０の外部の空気の温度Ｔａを取得する（ステップＳ１１）。なお、温度Ｔｈと温度Ｔｌとの温度差ΔＴとする。 The temperature controller 70 includes a temperature Th of the high temperature side thermoelectric element 5a output from the high temperature side thermometer 6a, a temperature Tl of the low temperature side thermoelectric element 5b output from the low temperature side thermometer 6b, and a thermohygrometer 6c. The humidity Ha of the air outside the dew condensation device 10 and the temperature Ta of the air outside the dew condensation device 10 that have been output from are acquired (step S11). It is assumed that the temperature difference ΔT between the temperature Th and the temperature Tl.
　露点温度算出部７１は、温度制御部７０が取得した空気の湿度Ｈａと、空気の温度Ｔａとから、結露装置１０の外部の空気の露点温度Ｔｄを算出すると共に、算出した露点温度Ｔｄから、温度Ｔｌの目標設定温度Ｔｔを設定する（ステップＳ１２）。 The dew point temperature calculation unit 71 calculates the dew point temperature Td of the air outside the dew condensation device 10 from the air humidity Ha acquired by the temperature control unit 70 and the air temperature Ta, and from the calculated dew point temperature Td, A target set temperature Tt for the temperature Tl is set (step S12).
　ここで、露点温度算出部７１は、目標設定温度Ｔｔを、算出した露点温度Ｔｄより低くなる（Ｔｄ＞Ｔｔ）ように設定する。目標設定温度Ｔｔは、露点温度算出部７１が算出した露点温度Ｔｄから値を演算できるように、設定方法（演算方法）を温度制御部７０に記憶しておく。 Here, the dew point temperature calculation unit 71 sets the target set temperature Tt to be lower than the calculated dew point temperature Td (Td> Tt). A setting method (calculation method) is stored in the temperature control unit 70 so that the target set temperature Tt can be calculated from the dew point temperature Td calculated by the dew point temperature calculation unit 71.
　そして、露点温度算出部７１は、算出した露点温度Ｔｄと、設定した目標設定温度Ｔｔとを冷却ファン駆動制御部７２に出力する。 The dew point temperature calculating unit 71 outputs the calculated dew point temperature Td and the set target set temperature Tt to the cooling fan drive control unit 72.
　冷却ファン駆動制御部７２は、露点温度算出部７１から取得した露点温度Ｔｄが、Ｔｄ≦０℃のとき（ステップＳ１３のＹＥＳ）、冷却ファン２を停止するように制御する。これにより、冷却ファン２は駆動を停止する（ステップＳ１４）。そして、ステップＳ１１の処理に戻る。 The cooling fan drive control unit 72 controls the cooling fan 2 to stop when the dew point temperature Td acquired from the dew point temperature calculation unit 71 is Td ≦ 0 ° C. (YES in step S13). Thereby, the cooling fan 2 stops driving (step S14). And it returns to the process of step S11.
　これは、０℃以下では水が凍ってしまうためである。すなわち、露点温度ＴｄがＴｄ≦０℃のときは、結露装置１０内の結露３が凍ってしまい、結露３を回収することができない。このため、露点温度ＴｄがＴｄ＞０℃のとき、すなわち、冷却ファン駆動制御部７２は、冷却ファン２を、結露３が回収できるときにのみ運転させる。 This is because water freezes below 0 ° C. That is, when the dew point temperature Td is Td ≦ 0 ° C., the dew condensation 3 in the dew condensation apparatus 10 is frozen, and the dew condensation 3 cannot be recovered. For this reason, when the dew point temperature Td is Td> 0 ° C., that is, the cooling fan drive controller 72 operates the cooling fan 2 only when the dew condensation 3 can be recovered.
　ステップＳ１３で、Ｔｄ＞０のとき（ステップＳ１３のＮＯ）、冷却ファン駆動制御部７２は、露点温度算出部７１から取得した目標設定温度Ｔｔと、温度制御部７０が取得した温度Ｔ１とを比較し、温度Ｔｌを０（℃）＜Ｔｌ（℃）＜Ｔｔ（℃）となるように、冷却ファン２の回転数Ｒや、冷却ファン２のオン、オフ時間を制御する。 In step S13, when Td> 0 (NO in step S13), the cooling fan drive controller 72 compares the target set temperature Tt acquired from the dew point temperature calculator 71 with the temperature T1 acquired by the temperature controller 70. Then, the rotational speed R of the cooling fan 2 and the on / off time of the cooling fan 2 are controlled so that the temperature Tl becomes 0 (° C.) <Tl (° C.) <Tt (° C.).
　すなわち、冷却ファン駆動制御部７２は、温度制御部７０が取得した温度Ｔｌが、０（℃）＜Ｔｌ（℃）＜Ｔｔ（℃）であれば（ステップＳ１５のＹＥＳ）、冷却ファン２の回転数Ｒをそのまま維持するように制御する。これにより、冷却ファン２は、回転数Ｒをそのまま維持して駆動する（ステップＳ１６）。そして、ステップＳ１１に戻る。 That is, the cooling fan drive control unit 72 rotates the cooling fan 2 if the temperature Tl acquired by the temperature control unit 70 is 0 (° C.) <Tl (° C.) <Tt (° C.) (YES in step S15). Control is performed so as to maintain the number R as it is. As a result, the cooling fan 2 is driven while maintaining the rotational speed R (step S16). Then, the process returns to step S11.
　また、冷却ファン駆動制御部７２は、温度制御部７０が取得した温度Ｔｌが、Ｔｌ（℃）≧Ｔｔ（℃）であると判定すると（ステップＳ１５のＮＯの後、ステップＳ１７のＹＥＳ）、冷却ファン２の回転数Ｒを上げるように制御する。これにより、冷却ファン２は、回転数Ｒを上げて駆動し（ステップＳ１８）、温度Ｔｌが目標設定温度Ｔｔより小さくなるように熱電素子５ａ・５ｂの温度を制御する。 In addition, when the cooling fan drive control unit 72 determines that the temperature Tl acquired by the temperature control unit 70 is Tl (° C.) ≧ Tt (° C.) (NO in step S15, YES in step S17), cooling Control is performed to increase the rotational speed R of the fan 2. Thereby, the cooling fan 2 is driven by increasing the rotation speed R (step S18), and controls the temperature of the thermoelectric elements 5a and 5b so that the temperature Tl becomes smaller than the target set temperature Tt.
　また、ステップＳ１７でＮＯの場合、Ｔｌ（℃）≦０（℃）なので、冷却ファン駆動制御部７２は、冷却ファン２の回転数Ｒを下げるか、冷却ファン２の駆動を停止するように制御する。これにより、冷却ファン２は、回転数Ｒを下げるか、駆動を停止し（ステップＳ１９）、温度Ｔｌが０℃より大きくなるように、熱電素子５ａ・５ｂの温度を制御する。そして、ステップＳ１１に戻る。 If NO in step S17, since Tl (° C.) ≦ 0 (° C.), the cooling fan drive control unit 72 controls to reduce the rotation speed R of the cooling fan 2 or to stop driving the cooling fan 2. To do. Thereby, the cooling fan 2 reduces the rotation speed R or stops driving (step S19), and controls the temperature of the thermoelectric elements 5a and 5b so that the temperature Tl becomes higher than 0 ° C. Then, the process returns to step S11.
　また、ステップＳ１１の処理の際、あわせて、温度管理部７３が、温度制御部７０が取得した温度Ｔｈや、温度差ΔＴが異常な値（予め設定された限界値を越える値）になっていないかを監視するようにしてもよい。 In addition, at the time of the process of step S11, the temperature management unit 73 also has an abnormal value (a value exceeding a preset limit value) for the temperature Th acquired by the temperature control unit 70 and the temperature difference ΔT. You may make it monitor whether there is.
　温度管理部７３は、温度Ｔｈや、温度差ΔＴが異常な値となっていると判定すると、冷却ファン駆動制御部７２に動作停止通知を出力する。冷却ファン駆動制御部７２は、温度管理部７３から動作停止通知を取得すると、冷却ファン２の駆動を強制的に停止する。 When the temperature management unit 73 determines that the temperature Th and the temperature difference ΔT are abnormal values, the temperature management unit 73 outputs an operation stop notification to the cooling fan drive control unit 72. When the cooling fan drive control unit 72 receives the operation stop notification from the temperature management unit 73, the cooling fan drive control unit 72 forcibly stops driving the cooling fan 2.
　このように、冷却ファン駆動制御部７２は、熱電素子５ｂの温度Ｔｌを、露点温度Ｔｄより温度が低い目標設定温度Ｔｔより低くなるように冷却ファン２の回転数Ｒを制御する。このため、熱電素子５ｂの温度Ｔｌを、確実に、露点温度Ｔｄより小さくすることができ、結露発生の効率を向上させることができる。 Thus, the cooling fan drive control unit 72 controls the rotational speed R of the cooling fan 2 so that the temperature Tl of the thermoelectric element 5b is lower than the target set temperature Tt that is lower than the dew point temperature Td. For this reason, the temperature Tl of the thermoelectric element 5b can be reliably made smaller than the dew point temperature Td, and the efficiency of dew condensation generation can be improved.
　なお、結露発生の効率は下がるが、目標設定温度Ｔｔを設定せず、ステップＳ１５で、冷却ファン駆動制御部７２は、温度Ｔｌを０（℃）＜Ｔｌ（℃）＜Ｔｄ（℃）の範囲内となるように冷却ファン２の回転数Ｒを制御するようにしてもよい。 Although the efficiency of dew condensation is reduced, the target set temperature Tt is not set, and in step S15, the cooling fan drive controller 72 sets the temperature Tl to a range of 0 (° C.) <Tl (° C.) <Td (° C.). You may make it control the rotation speed R of the cooling fan 2 so that it may become inside.
　次に、熱電素子５ａ・５ｂの温度制御の具体例について説明する。 Next, a specific example of temperature control of the thermoelectric elements 5a and 5b will be described.
　温度制御部７０は、以下のように、熱電素子５ａ・５ｂの温度制御を行う。 The temperature controller 70 controls the temperature of the thermoelectric elements 5a and 5b as follows.
　一例として、目標設定温度Ｔｔを、Ｔｔ＝Ｔｄ／２として演算するように設定方法が温度制御部７０に記憶されている場合について説明する。また、前提としてΔＴ＝２５（℃）とする。 As an example, a case where a setting method is stored in the temperature control unit 70 so as to calculate the target set temperature Tt as Tt = Td / 2 will be described. As a premise, ΔT = 25 (° C.).
　温度制御部７０は、温湿度計６ｃから温度Ｔａ＝２５℃及び湿度Ｈａ＝４０％ＲＨを取得する（ステップＳ１１）。また、温度制御部７０は、高温側温度計６ａから出力されてきた高温側の熱電素子５ａの温度Ｔｈ＝３０．２（℃）、低温側温度計６ｂから出力されてきた低温側の熱電素子５ｂの温度Ｔｌ＝５．２（℃）を取得する（ステップＳ１１）。 Temperature controller 70 acquires temperature Ta = 25 ° C. and humidity Ha = 40% RH from thermohygrometer 6c (step S11). Further, the temperature control unit 70 includes a temperature Th = 30.2 (° C.) of the high temperature side thermoelectric element 5a output from the high temperature side thermometer 6a, and a low temperature side thermoelectric element output from the low temperature side thermometer 6b. The temperature Tl = 5.2 (° C.) of 5b is acquired (step S11).
　また、温度管理部７３は、温度制御部７０が取得した温度Ｔ＝３０．２℃や、温度Ｔｌ＝５．２℃と温度Ｔ＝３０．２℃との温度差ΔＴ２５℃が異状な値になっているか否かを監視する。 Further, the temperature management unit 73 sets the temperature T = 30.2 ° C. acquired by the temperature control unit 70 or the temperature difference ΔT 25 ° C. between the temperature Tl = 5.2 ° C. and the temperature T = 30.2 ° C. to an abnormal value. Monitor whether or not
　次に、露点温度算出部７１は、温度制御部７０が取得した温度Ｔａ＝２５℃及び湿度Ｈａ＝４０％ＲＨから、露点温度Ｔｄ＝１０．５℃と算出し、さらに、算出した露点温度Ｔｄ＝１０．５℃から目標設定温度Ｔｔを５．２５℃（＝Ｔｄ／２）と算出し、設定する（ステップＳ１２）。露点温度算出部７１は、算出した露点温度Ｔｄ＝１０．５℃、及び設定した目標設定温度Ｔｔ＝５．２５℃を冷却ファン駆動制御部７２に出力する。 Next, the dew point temperature calculation unit 71 calculates the dew point temperature Td = 10.5 ° C. from the temperature Ta = 25 ° C. and the humidity Ha = 40% RH acquired by the temperature control unit 70, and further calculates the calculated dew point temperature Td. The target set temperature Tt is calculated as 5.25 ° C. (= Td / 2) from 10.5 ° C. and set (step S12). The dew point temperature calculation unit 71 outputs the calculated dew point temperature Td = 10.5 ° C. and the set target set temperature Tt = 5.25 ° C. to the cooling fan drive control unit 72.
　次に、冷却ファン駆動制御部７２は、露点温度Ｔｄ＝１０．５℃が０℃より大きいので（ステップＳ１３のＮＯ）、冷却ファン駆動制御部７２は、露点温度算出部７１から取得した目標設定温度Ｔｔ＝５．２５℃と、温度制御部７０が取得した温度Ｔｌ＝５．２℃とを比較する。そして、冷却ファン駆動制御部７２は、温度Ｔｌ＝５．２℃が、目標設定温度Ｔｔ＝５．２５℃を下回っており、０℃より大きいので（ステップＳ１５のＹＥＳ）、回転数Ｒをそのまま維持するように冷却ファン２の駆動を制御する。これにより、冷却ファン２の回転数Ｒはそのまま維持される（ステップＳ１６）。 Next, since the dew point temperature Td = 10.5 ° C. is higher than 0 ° C. (NO in step S13), the cooling fan drive controller 72 sets the target setting acquired from the dew point temperature calculator 71. The temperature Tt = 5.25 ° C. is compared with the temperature Tl = 5.2 ° C. acquired by the temperature control unit 70. Then, the cooling fan drive controller 72 determines that the temperature Tl = 5.2 ° C. is lower than the target set temperature Tt = 5.25 ° C. and higher than 0 ° C. (YES in step S15), so that the rotational speed R remains unchanged. The driving of the cooling fan 2 is controlled so as to be maintained. Thereby, the rotation speed R of the cooling fan 2 is maintained as it is (step S16).
　（水分量調整部６０の処理の流れ）
　図４を用いて、水分量調整部６０の処理の流れについて説明する。 (Processing flow of the water content adjusting unit 60)
With reference to FIG. 4, the flow of processing of the moisture amount adjusting unit 60 will be described.
　図４は、植物栽培システム１の水分量調整部６０の処理の流れを説明する図である。 FIG. 4 is a diagram for explaining the flow of processing of the water content adjustment unit 60 of the plant cultivation system 1.
　一例として、土４３の水分量を４０％以上６０％以下で管理する場合、水分量記憶部６１に、予め、土４３の水分量の下限値４０％と、上限値６０％とを設定し記憶しておく（ステップＳ２１）。水分量調整部６０を動作させると、水分量調整部６０は、水分量記憶部６１に記憶されている土４３の水分量の下限値４０％と、上限値６０％とを取得する。 As an example, when managing the moisture content of the soil 43 at 40% or more and 60% or less, a lower limit value 40% and an upper limit value 60% of the moisture content of the soil 43 are set and stored in the moisture content storage unit 61 in advance. (Step S21). When the moisture amount adjusting unit 60 is operated, the moisture amount adjusting unit 60 acquires the lower limit value 40% and the upper limit value 60% of the moisture amount of the soil 43 stored in the moisture amount storage unit 61.
　そして、土壌水分センサ４４は、土４３の水分量を測定したデータを、所定時間間隔（例えば１秒おき）に、水分量調整部６０に出力する。 Then, the soil moisture sensor 44 outputs data obtained by measuring the moisture content of the soil 43 to the moisture content adjusting unit 60 at predetermined time intervals (for example, every 1 second).
　水分量調整部６０は、土壌水分センサ４４から出力されてくる土４３の水分量の測定データを取得し（ステップＳ２２）、常時監視する。 The moisture content adjustment unit 60 acquires the measurement data of the moisture content of the soil 43 output from the soil moisture sensor 44 (step S22) and constantly monitors it.
　そして、水分量調整部６０は、土壌水分センサ４４から出力されてくる土４３の水分量の測定データで、土４３の水分量が下限値（４０％）を下回ったと判定すると（Ｓ２３のＹＥＳ）、水分量調整部６０は、送液装置３０を、水分の供給速度を増加させるように制御する。これにより、送液装置３０は、水分の供給速度を増加させる（ステップＳ２４）。そして、ステップＳ１２の処理に戻る。 And if the moisture content adjustment part 60 determines with the moisture content measurement data of the soil 43 output from the soil moisture sensor 44 that the moisture content of the soil 43 has fallen below a lower limit (40%) (YES of S23). The water content adjusting unit 60 controls the liquid feeding device 30 to increase the water supply rate. Thereby, the liquid feeding apparatus 30 increases the supply speed | rate of a water | moisture content (step S24). Then, the process returns to step S12.
　水分量調整部６０は、ステップＳ１３の処理でＮＯと判定したあと、土壌水分センサ４４から出力されてくる土４３の水分量の測定データで、土４３の水分量が上限値（６０％）を上回ったと判定すると（Ｓ２５のＹＥＳ）、水分量調整部６０は、送液装置３０を、水分の供給を停止するように制御する。これにより、送液装置３０は、水分の供給を停止する（ステップＳ２６）。そして、ステップＳ２２の処理に戻る。 After determining NO in the process of step S13, the moisture content adjusting unit 60 is the measurement data of the moisture content of the soil 43 output from the soil moisture sensor 44, and the moisture content of the soil 43 has an upper limit value (60%). If it determines with having exceeded (YES of S25), the moisture content adjustment part 60 will control the liquid feeding apparatus 30 to stop supply of a water | moisture content. Thereby, the liquid feeding apparatus 30 stops supply of a water | moisture content (step S26). Then, the process returns to step S22.
　また、土壌水分センサ４４から出力されてくる土４３の水分量の測定データには測定ラグがある。 In addition, the measurement data of the moisture content of the soil 43 output from the soil moisture sensor 44 includes a measurement lag.
　このため、例えば、ステップＳ２２で、水分量調整部６０は、土壌水分センサ４４から出力されてくる土４３の水分量の測定データを取得すると（ステップＳ２２）、前回、取得した水分量の測定データと比較し、水分量の増加量が大きいと判定した場合、水分量調整部６０は、送液装置３０を、水分の供給速度を減少させるように制御するようにしてもよい。これにより、送液装置３０は、水分の供給速度を減少させる。そして、ステップＳ２３以降の処理を行う。 Therefore, for example, when the moisture content adjustment unit 60 acquires the measurement data of the moisture content of the soil 43 output from the soil moisture sensor 44 in step S22 (step S22), the moisture content measurement data acquired last time is obtained. When it is determined that the increase amount of the water amount is large, the water amount adjustment unit 60 may control the liquid feeding device 30 so as to decrease the water supply speed. Thereby, the liquid feeding apparatus 30 reduces the supply speed | rate of a water | moisture content. And the process after step S23 is performed.
　〔実施の形態２〕
　次に、図５、６を用いて、本発明の第２の実施の形態に係る植物栽培システムの構成について説明する。なお、説明の便宜上、前記実施の形態１にて説明した図面と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 2]
Next, the structure of the plant cultivation system which concerns on the 2nd Embodiment of this invention is demonstrated using FIG. For convenience of explanation, members having the same functions as those in the drawings described in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.
　図５は、第２の実施の形態にかかる植物栽培システム１００の結露装置（水生成装置）１１０の構成を表す図である。図６は、第２の実施の形態に係る結露装置１１０が備えている結露発生器１１１の構成を表す斜視図である。 FIG. 5 is a diagram illustrating a configuration of a dew condensation device (water generation device) 110 of the plant cultivation system 100 according to the second embodiment. FIG. 6 is a perspective view illustrating a configuration of a dew condensation generator 111 provided in the dew condensation apparatus 110 according to the second embodiment.
　本実施の形態に係る植物栽培システム１００は、植物栽培システム１が備えていた結露装置１０に替えて、結露装置１１０を備えている点で、植物栽培システム１と相違する。植物栽培システム１００の他の構成は植物栽培システム１と同様である。 The plant cultivation system 100 according to the present embodiment is different from the plant cultivation system 1 in that a condensation device 110 is provided instead of the condensation device 10 provided in the plant cultivation system 1. Other configurations of the plant cultivation system 100 are the same as those of the plant cultivation system 1.
　結露装置１１０は、結露発生器１１１を備えている点で、結露装置１０と相違する。結露装置１１０の他の構成は、結露装置１０と同様である。 The dew condensation device 110 is different from the dew condensation device 10 in that it includes a dew condensation generator 111. Other configurations of the dew condensation device 110 are the same as those of the dew condensation device 10.
　結露発生器１１１は、本体内部１１ａであり、熱電素子格納部１５の底面（すなわち、本体内部１１ａの上面）に配されている。結露発生器１１１は、基板１１２と、複数の突起部１１３とから構成されている。 The dew generator 111 is inside the main body 11a, and is arranged on the bottom surface of the thermoelectric element storage 15 (that is, the top surface of the main body inside 11a). The dew condensation generator 111 includes a substrate 112 and a plurality of protrusions 113.
　基板１１２と、複数の突起部１１３とは、例えば、アルミニウムや銅などから構成されている。 The substrate 112 and the plurality of protrusions 113 are made of, for example, aluminum or copper.
　基板１１２は、複数の突起部１１３の土台である。基板１１２は、一方の面に複数の突起部１１３が配されている。そして、基板１１２の他方の面は、本体内部１１ａの熱電素子格納部１５の底面（すなわち、本体内部１１ａの上面）に配されている。このように、結露発生器１１１は、熱電素子格納部１５に格納されている熱電素子５ａ・５ｂのうち、低温側の熱電素子５ｂの近傍に配されている。 The substrate 112 is a base for the plurality of protrusions 113. The substrate 112 has a plurality of protrusions 113 on one surface. The other surface of the substrate 112 is disposed on the bottom surface of the thermoelectric element storage 15 in the main body interior 11a (that is, the upper surface of the main body interior 11a). As described above, the dew condensation generator 111 is arranged in the vicinity of the low-temperature-side thermoelectric element 5b among the thermoelectric elements 5a and 5b stored in the thermoelectric element storage unit 15.
　突起部１１３は、例えば、四角柱や円柱などの柱状形状である。突起部１１３の基部は、基板１１２に配されており、先端部は本体底部１７と離間している。なお、突起部１１３の先端部は尖っていてもよい。 The protrusion 113 has, for example, a columnar shape such as a square column or a cylinder. The base of the projection 113 is disposed on the substrate 112, and the tip is separated from the main body bottom 17. Note that the tip of the protrusion 113 may be sharp.
　このように、結露装置１１０は、本体内部１１ａであり、熱電素子格納部１５ａの下面に、基板１２を介して、複数の突起部１１３が配されている。
本体内部１１ａに、多数の突起部１１３が配された結露発生器１１１を備えている。このため、空気用フィルタ１６を通過し、本体内部１１ａに流入した空気は、多数の突起部１１３や、基板１１２と接触することで、多数の突起部１１３や基板１１２で結露３が発生する。このように、結露装置１１０は、多数の突起部１１３が配されているので、本体内部１１ａの空気の接触面積が大きくなり、本体内部１１ａでの結露の発生効率を向上させることができる。 As described above, the dew condensation device 110 is the inside 11a of the main body, and a plurality of protrusions 113 are arranged on the lower surface of the thermoelectric element storage portion 15a via the substrate 12.
A dew condensation generator 111 in which a large number of protrusions 113 are arranged is provided inside the main body 11a. For this reason, the air that has passed through the air filter 16 and has flowed into the inside 11 a of the main body comes into contact with the large number of protrusions 113 and the substrate 112, so that condensation 3 occurs at the large number of protrusions 113 and the substrate 112. Thus, since the dew condensation device 110 is provided with a large number of protrusions 113, the air contact area in the main body interior 11a is increased, and the generation efficiency of dew condensation in the main body interior 11a can be improved.
　また、多数の突起部１１３は、本体内部１１ａの上面（すなわち、熱電素子格納部１５の下面）から、下方に向けて突出するように配されている。このため、突起部１１３の表面や、基板１１２の表面で発生して結露３は、突起部１１３を伝って、速やかに重力により下方に移動する。このため、結露の発生効率を良くすることができる。 Further, the large number of protrusions 113 are arranged so as to protrude downward from the upper surface of the main body interior 11a (that is, the lower surface of the thermoelectric element storage portion 15). For this reason, the dew condensation 3 generated on the surface of the protrusion 113 and the surface of the substrate 112 is quickly moved downward by gravity through the protrusion 113. For this reason, the generation efficiency of dew condensation can be improved.
　さらに、突起部１１３の表面や、基板１１２の表面で発生して結露３は、速やかに下方に移動するため、水滴が集まりやすくなり、水滴が大きくなり、速やかに、突起部１１３の先端部から、本体内部１１ａの下方へと落下させることができる。このため、結露３を収集する効率を向上させることができる。 Furthermore, since the condensation 3 generated on the surface of the protrusion 113 and the surface of the substrate 112 quickly moves downward, water droplets are likely to collect, the water droplets become large, and immediately from the tip of the protrusion 113. , And can be dropped below the inside 11a of the main body. For this reason, the efficiency which collects the dew condensation 3 can be improved.
　〔実施の形態３〕
　次に、図７を用いて、本発明の第３の実施の形態に係る植物栽培システムの構成について説明する。なお、説明の便宜上、前記実施の形態１、２にて説明した図面と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 3]
Next, the structure of the plant cultivation system which concerns on the 3rd Embodiment of this invention is demonstrated using FIG. For convenience of explanation, members having the same functions as those in the drawings described in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.
　図７は、第３の実施の形態にかかる植物栽培システム１０１の結露装置１０及び冷却ファン２の構成を表す図である。 FIG. 7 is a diagram illustrating the configuration of the dew condensation device 10 and the cooling fan 2 of the plant cultivation system 101 according to the third embodiment.
　実施形態１、２では、冷却ファン２は、熱電素子格納部１５の上面と触れるようにして、水平方向に空気Ａを送風していた。一方、本実施の形態に係る植物栽培栽培システム１０１では、冷却ファン２は、熱電素子格納部１５の上方に配されており、熱電素子格納部１５の上面に向けて、鉛直方向下向きに空気Ａを送風する。 In Embodiments 1 and 2, the cooling fan 2 blows the air A in the horizontal direction so as to touch the upper surface of the thermoelectric element storage unit 15. On the other hand, in the plant cultivation and cultivation system 101 according to the present embodiment, the cooling fan 2 is disposed above the thermoelectric element storage unit 15, and the air A is directed vertically downward toward the upper surface of the thermoelectric element storage unit 15. To blow.
　冷却ファン２から送風された空気Ａは、熱電素子格納部１５の上面に触れると、熱電素子格納部１５の上面の近傍に配されている高温側の熱電素子５ａによって温められる。そして、温められた空気Ａは、空気用フィルタ１６の外側表面を伝って、結露装置１０の下方に送られる。このため、空気用フィルタ１６の外側表面は、空気Ａによって温められる。 When the air A blown from the cooling fan 2 touches the upper surface of the thermoelectric element storage unit 15, it is warmed by the high temperature side thermoelectric element 5 a disposed in the vicinity of the upper surface of the thermoelectric element storage unit 15. The warmed air A is sent below the dew condensation device 10 along the outer surface of the air filter 16. For this reason, the outer surface of the air filter 16 is warmed by the air A.
　このように、空気用フィルタ１６の外側表面を温めることで、空気用フィルタ１６の外側表面に結露が発生することを防止することができる。これにより、空気用フィルタ１６の孔に結露３が付着することにより孔が塞がれ、空気用フィルタ１６を通って、本体内部１１ａに流入する空気の量が低下することを防止することができ、本体内部１１ａで発生する結露３の量が低下することを防止することができる。 Thus, by heating the outer surface of the air filter 16, it is possible to prevent dew condensation from occurring on the outer surface of the air filter 16. This prevents the condensation 3 from adhering to the holes of the air filter 16 so that the holes are blocked, and the amount of air flowing into the main body interior 11a through the air filter 16 can be prevented from decreasing. It is possible to prevent the amount of condensation 3 generated in the main body inside 11a from being lowered.
　本発明は上述した各実施形態に限定されるものではなく、請求項に示した範囲で種々の変更が可能であり、異なる実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本発明の技術的範囲に含まれる。 The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments.

　さらに、上記本体の下方に、上記水用フィルタが配されているので、上記本体底部の開口に導かれた上記本体の内部で発生した結露は、重力により上記開口を流れ、上記水用フィルタを透過する。これにより、さらに、上記本体の内部で発生した結露のバクテリア、カビや藻類の胞子等が除菌される。 Further, since the water filter is arranged below the main body, the dew condensation generated inside the main body led to the opening at the bottom of the main body flows through the opening due to gravity, and the water filter is To Penetrate. This further sterilizes condensation bacteria, mold, algae spores and the like generated inside the main body.
　そして、上記水用フィルタを透過した、上記本体の内部で発生した結露は、上記供給管を流れ、上記植物に供給される。このようにして、植物に供給する水としては、充分に除菌された水を上記植物に供給することができる。 And the dew condensation generated inside the main body that has passed through the water filter flows through the supply pipe and is supplied to the plant. In this way, as the water supplied to the plant, sufficiently sterilized water can be supplied to the plant.
　このように、上記構成によると、簡単な構成で、上記植物に供給する水を生成することができる。 Thus, according to the above configuration, water to be supplied to the plant can be generated with a simple configuration.

　また、上記熱電素子格納部と、上記空気用フィルタと、上記本体底部とは、上方から下方に向けて順に配されていることが好ましい。上記構成により、上記熱電素子格納部と、上記本体底部との間は、上記空気用フィルタが配されているので、上記熱電素子格納部と、上記本体底部とは離間して配されることになる。このため、上記本体の内部の体積が大きくなり、空気用フィルタを通って、本体の内部に多くの空気を流入させることができるので、本体の内部で効率よく結露を発生させることができる。 Moreover, it is preferable that the thermoelectric element storage unit, the air filter, and the main body bottom are arranged in order from the top to the bottom. With the above configuration, since the air filter is arranged between the thermoelectric element storage part and the main body bottom part, the thermoelectric element storage part and the main body bottom part are arranged apart from each other. Become. For this reason, since the volume inside the said main body becomes large and it can flow in into the inside of a main body through the filter for air, dew condensation can be efficiently generated inside a main body.
　さらに、上記本体底部は、上記熱電素子格納部の下方に配されているので、熱電素子格納部の表面に付着した結露は重力により、上記本体底部に落下する。そして、当該落下した結露を回収される。このため、簡単な構成で、上記熱電素子格納部に付着した結露を回収することができる。 Furthermore, since the bottom part of the main body is arranged below the thermoelectric element storage part, the dew that adheres to the surface of the thermoelectric element storage part falls to the bottom part of the main body due to gravity. And the fallen dew condensation is collected. For this reason, the dew condensation adhering to the said thermoelectric element storage part can be collect | recovered with a simple structure.
　また、上記本体の内部であり、上記熱電素子格納部の下面には、複数の突起部が配されていることが好ましい。上記構成によると、上記本体の内部の多くの空気が、上記複数の突起部と接触することになるので、上記複数の突起部の表面で、多くの結露を発生させることができる。これにより、結露の発生効率を向上することができる。 Also, it is preferable that a plurality of protrusions are arranged inside the main body and on the lower surface of the thermoelectric element storage unit. According to the above configuration, since a large amount of air inside the main body comes into contact with the plurality of protrusions, a large amount of condensation can be generated on the surfaces of the plurality of protrusions. Thereby, the generation efficiency of dew condensation can be improved.
　また、上記本体の内部の気圧は、大気圧より低いことが好ましい。上記構成により、上記空気用フィルタを通して、外部の空気を本体の内部に流入させることができる。 Moreover, it is preferable that the pressure inside the main body is lower than the atmospheric pressure. With the above configuration, external air can be introduced into the main body through the air filter.

The temperature of the element can be adjusted.
　このため、上記熱電素子を、外気の環境に適した温度に設定することができる。 Therefore, the thermoelectric element can be set to a temperature suitable for the outside air environment.
　また、本発明の植物栽培システムは、上記植物供給用の水生成装置と、上記熱電素子格納部の上方に配されており、上記熱電素子格納部の上面に向けて風を送る送風部とを備えていることが好ましい。 Moreover, the plant cultivation system of the present invention includes the water generating device for supplying the plant and a blower unit that is arranged above the thermoelectric element storage unit and sends wind toward the upper surface of the thermoelectric element storage unit. It is preferable to provide.
　上記構成によると、上記送風部は、上方から下方に向けて順に配されている上記熱電素子格納部と、上記空気用フィルタと、上記本体底部とのうち、上記熱電素子格納部の上面に向けて風を送る。このため、上記送風部から送られた風は、上記熱電素子格納部で温められ、当該温められた風が上記空気フィルタの外側表面を伝って、下方に送られる。これにより、上記空気フィルタの外側表面は、上記送風部から送られた風によって温められる。 According to the said structure, the said ventilation part is toward the upper surface of the said thermoelectric element storage part among the said thermoelectric element storage parts, the said air filter, and the said main body bottom part which are distribute | arranged in order toward the downward direction from the upper direction.
