PROBLEM TO BE SOLVED: To provide a container type water level adjuster for hydroponics that is to be set in the exterior of a water tank, the container type water level adjuster for hydroponics being obtained by simplifying the interior of a water level adjuster by means of suppressing the amount of water to necessary and sufficient amount in order to make its size small enough to rest on the palm, because conventionally a water level adjuster for hydroponics aiming at automatic water supply is large and difficult to handle as home use.SOLUTION: A tube joint is mounted on the lid of a water level adjustor 1, and a nutrient solution is flowed out from a water tank into the water level adjustor 1 with a tube. The interior of the water level adjuster is provided with a float 1f, a gel resin adhesion pad 1g is put on it, the tip of a joint 1d of the inside of the lid and the adhesion pad 1g are pressure-bonded by the buoyancy of the float 1f, and thereby a feed valve can exert the function of opening and closing. A tube joint 1e is mounted on the lower part of the container to flow out the nutrient solution into a water tank pot 5 using a tube 3 from the outside terminal. The water level adjuster 1 is put on the installation stand 1i between a water tank 4 and the water tank pot 5 and connected to them with a tube, and the water level is adjusted by changing the height of the installation stand 1i.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 従来、自動給水を目的とした水耕栽培用水位調整器は家庭用としては大型で扱いにくかった。そこでこれを手のひらに載るサイズにするため、必要十分な水量の仕様に抑えることにより、水位調整器内部を簡素化し、水槽外部に置く容器型とする。【解決手段】 水位調整器1の蓋にチューブ継手を取り付け、チューブにより貯水槽から養液を水位調整器1に入水する。水位調整器1の内部にフロート1fを設け、その上にゲル状樹脂の接着パッド1gを載せ、フロート1fの浮力により蓋内側の継手1d先端部と接着パッド1gを圧着させ給水弁を開閉する機能を果たさせる。そして同容器の下部にチューブ継手1eを取り付け、外側端子部からチューブ3を使用して水槽鉢5に養液を出水する。 水位調整器1は貯水槽4と水槽鉢5の間の設置台1iに置き、チューブでつなぎ、設置台1iの高さを変えることによって、水位を調整する。【選択図】図1
