PROBLEM TO BE SOLVED: To provide a plant cultivation apparatus that has few limitations as to the place of installation.SOLUTION: The plant cultivation apparatus 1 includes a cultivation liquid container 3 for retaining a cultivation liquid, openings 30, 33 for allowing the cultivation liquid to flow into the cultivation liquid container 3, and an opening 24 for allowing the cultivation liquid retained in the cultivation liquid container 3 to flow out of the cultivation liquid container 3. The amount of the cultivation liquid that is allowed to flow into the cultivation liquid container 3 through the openings 30, 33 and the amount of the liquid allowed to flow out of the opening 24 are set to be equal when a predetermined amount of cultivation liquid is retained in the cultivation liquid container 3. The plant cultivation apparatus 1 also includes a cultivation liquid tank 5 for retaining the cultivation liquid, a liquid pump 6 for sending the cultivation liquid out from the cultivation liquid tank 5 to the cultivation liquid container 3, and a rack on which the cultivation liquid container 3, the cultivation liquid tank 5 and the liquid pump 6 are mounted. The openings 30, 33 allow the cultivation liquid to flow into a portion of the cultivation liquid container 3. The opening 24 allows the cultivation liquid to flow out of a portion of the cultivation liquid container 3. The openings 30, 33 and the opening 24 are arranged in positions crossing the inside of the cultivation liquid container 3.COPYRIGHT: (C)2013,JPO&INPIT【課題】設置場所の制限の少ない植物栽培装置を提供する。【解決手段】栽培液が貯留される栽培液槽3と、栽培液槽3内に栽培液を流入させる開口部30、33と、栽培液槽3内に溜められた栽培液を栽培液槽3から流出させる開口部24とを備え、開口部30、33から栽培液槽3内に流入される栽培液の流入量と、開口部24から流出される流出量とが、栽培液槽3内に所定量の栽培液が溜まった状態で等しくなるように設定されている植物栽培装置1において、栽培液が貯留される栽培液タンク5と、栽培液タンク5から栽培液槽3に栽培液を送出する液体ポンプ6と、栽培液槽3、栽培液タンク5および液体ポンプ6が取り付けられる棚体とを有し、開口部30、33は、栽培液槽3内の一箇所に栽培液を流入させ、開口部24は、栽培液槽3内の一箇所から栽培液を流出させ、開口部30、33と開口部24とは、栽培液槽3の槽内を横断する位置に配置されている。【選択図】図4
