201244626 六、發明說明： 【發明所屬之技術領域】 本發明是關於一種植栽裝置，具備：植栽容器、及吸 水性的植栽底材、以及供水手段；該植栽容器是具備：可 儲備植栽用水的貯水部；該吸水性的植栽底材是設置於貯 水部：該供水手段是將植栽用水供應於貯水部，將超過預 定高度的植栽用水予以排水的溢流管設於貯水部。 【先前技術】 做爲關連於此種植栽裝置的先前技術文獻資訊有表示 於下述的專利文獻1。在被記載於該專利文獻1的植栽裝 置中，若藉由泵浦等之供水手段將植栽用水供應於植栽容 器的貯水部，以未超過溢流管上端的水準下能夠把植栽用 水積存於貯水部。 有一部分被浸漬於其積存的植栽用水的植栽底材來抽 取植栽用水，並將適當量的植栽用水保持於內部之故，因 而可適當地栽培被種植於植栽底材的植物。 有超過植栽底材的吸水能力的水量的植栽用水被供應 時，或是供水手段所導致的植栽用水的供應速度超過植栽 底材的吸水速度時，多餘的植栽用水從溢流管被排水。 特別是，在上下地累積使用複數植栽容器時，從溢流 管所排水的植栽用水，是做爲被供應於設在下方的植栽容 器’最後使得累積所有植栽容器的植栽底材會吸水需要量 的植栽用水。 -5- 201244626 又’從被設置於最下段的植栽容器的溢流管所排水的 植栽用水，是被回收在適當的貯水容器，視需要，可利用 做爲下一次灌水用的植栽用水。 專利文獻1:日本特開2009-45015號公報（0021段 落，第2圖） 【發明內容】 但是，在一般最常用的使用方法中，爲了充分地吸水 於植栽底材，於植栽容器的貯水部會供應著超過植栽底材 的吸水能力的充分水量的植栽用水的情形。 此種情形，在被記載於專利文獻1的植栽裝置中，從 溢流管的上端往下有長期地放置超過一定量的植栽用水的 可能性，而若長期地放置植栽用水時，則有損及美觀之虞 〇 所以，本發明的目的是鑒於以上所例示的先前技術的 植栽裝置所給予的課題，提供一種植栽裝置，該植栽裝置 是即使於植栽容器的貯水部供應超過植栽底材的吸水能力 的水量的植栽用水，也不會損及美觀之虞的被抑制者。 依本發明所硏創之植栽裝置的特徵構成是在於， 具備：植栽容器、及供水手段：該植栽容器是具備： 可儲備植栽用水的貯水部與可載置吸水性的植栽底材的植 栽用空間；該供水手段是將植栽用水供應於上述貯水部， 將超過預定高度的植栽用水予以排水的溢流管設於上 述貯水部，並於上述貯水部的底面設有排水部，該排水部 201244626 所具備的排水能力是低於上述供水手段的供水速度。 在上述的特徵構成的植栽裝置中，於貯水部的底面設 有具備低於供水手段的供水速度的排水能力的排水部之故 ，因而在供水手段所導致的貯水部的供水終了的時機，未 被吸水在植栽底材，而留在貯水部的植栽用水，是藉由排 水部被排水。 因此，可避免植栽用水長時間被放置於貯水部，也不 會有黴菌發生於植栽底材，或是有害蟲發生於植栽用水等 之虞，又也不會損及美觀。 而且，因排水部的排水能力是低於供水手段的供水速 度，因此，供水手段所導致的對於貯水部的供水中，植栽 用水以適當的高度被保持於貯水部之故，因而植栽底材是 適當地吸水該植栽用水，而能夠出現保水之狀態。 本發明的其他特徵構造，是與上述溢流管連通的排水 管從上述貯水部朝下方突出形成，上述排水部是以連通上 述貯水部的底面與上述排水管的內面的方式所形成，爲其 特徵者。 例如，排水部是與溢流管或是排水管的設置位置被形 成於不同位置時，即使可進行多餘的植栽用水的排水，進 入排水部的植栽用水，是橫方向地沿著形成貯水部底面的 底壁構件下面而容易移動之故，因而也有隨著相同移動會 弄髒底壁構件下面的問題，或是從上下地累積的植栽容器 的境界朝外部滲出等的問題之虞。 但是，若爲本構造，則進入排水部的植栽用水，是首 201244626 先沿著從貯水部朝下方突出形成的排水管的內面朝下方移 動，並從該排水管下端掉落，一般成爲確實地到達至下段 的植栽容器的貯水部或是植栽底材的表面。 又’若爲本構造，則與進入排水部的植栽用水沿著該 排水管的外面朝下方移動的構造相比較，可將從最下端的 植栽容器的排水部被排水的植栽用水，利用外嵌於排水管 的軟管等確實地回收至合適的槽內。 本發明的其他特徵構造，是上述排水部是對於垂直方 向形成角度地延伸，爲其特徵者。 若爲本構造，則藉由本身重量從排水部朝下方被排水 的植栽用水，是因從排水部的正下方掉落至朝側方變位的 位置，因此，結果，被設置於低一層的植栽容器的植栽底 材成爲被灌水的情形而較理想。 本發明的其他特徵構造，是於上述排水部的側方設有 用來捕捉於植栽用水所含之異物的異物捕捉凸部，爲其特 徵者。 若爲本構造，則即使在被貯水於貯水部的植栽用水的 水面上、水中或是貯水部的底面附近有異物浮游時，也因 藉由異物捕捉凸部捕捉大部分此些異物’因此藉由此些異 物使得排水部不容易被閉塞’且能夠確保正常的排水狀態 【實施方式】 以下，一面參照圖式一面說明用來實施本發明的形態 -8 · 201244626 如第1圖所示地，本發明的植栽裝置，是具備：植栽 容器1、及電動式等的栗浦30(供水手段的一例）：該植 栽容器1是具備：可儲備植栽用水W的貯水部8;該泵浦 30是將植栽用水W供應於貯水部8。植栽容器1是具備 朝向合成樹脂製的橫方向地長的形狀。 僅使用1個植栽容器1也可以進行植栽，惟一般，將 植栽用空間2的開口部以朝向相同方向的狀態下，以上下 地累積複數植栽容器1的狀態被使用。這時候，視需要， 將角材17配置於累積多數層的植栽容器1的角部，利用 適當的連結具18能夠連結植栽容器1與角材17。 (植栽容器的槪略構造） 如第3圖所不地’各個的植栽容器1，是一體地具備 底壁3與從其底壁3的三邊朝上方豎設的一個長側壁4及 兩個短側壁5，而於內部形成植栽用空間2。更進一步， 由底壁3的上面的一部分，也一體地豎設與短側壁5平行 地延伸的三個隔間壁6。 因此，如第4圖所示地，當於植栽容器1的上面載置 並安裝其他的植栽容器1或蓋構件1 a，則植栽用空間2藉 由三個隔間壁6被區劃成4個單位植栽用空間2a，各單位 植栽用空間2a的開口部構造成位於前面。 由底壁3的前端是朝上方豎設有上下長度短的前壁7 ，使得植栽容器1的底壁3、長側壁4、短側壁5、隔間壁 -9- 201244626 6、前壁7互相地協動，形成用來貯水植栽用水w的貯水 部卜 貯水部8也利用隔間壁6被區劃成合計4個的單位貯 水部8a，被配置於各單位植栽用空間2a的下部，形成於 各隔間壁6與長側壁4之間的間隙，設定成功能做爲在橫 方向連通各單位貯水部8a彼此間的連通路9。 如第2圖所示地，植物P是被種植在海綿狀等的吸水 性材料所形成的植栽底材A，一般，於1個單位植栽用空 間2a載置有1個植栽底材A。 各單位貯水部8a的底壁3，是具備：後方底壁3a、 及前方底壁3b;該後方底壁3a是朝水平地延伸，該前方 底壁3b是從後方底壁3a的前端朝向各單位植栽用空間2a 的開口部側逐漸位於上方的方式朝向前方上昇的傾斜（傾 斜角α )。傾斜角α的數値是例如做成大約1 4°就可以。 被載置於單位植栽用空間2a的植栽底材Α的後端是 被載置於後方底壁3a，而該植栽底材A的前端是大槪被 載置於前方底壁3b的前端附近。 植栽底材A，是例如將保水性塡充材料（泥炭苔）、 氨基甲酸乙酯預聚體、聚酯系聚醇、水以100:120:1: 8 00等的比率（數値都是重量分）混合而成形成方適當的 形狀能夠調配。植栽底材A的形狀是並未特別加以限制， 能夠適用立方體、長方體，或是，圓柱狀等的各種形狀者 〇 在植栽容器1的後方底壁3a，朝向上方突設有當超過 -10- 201244626 預定高度的植栽用水W予以排水時，則將貯水部8內的 植栽用水W用來維持在一定量以下的溢流管10。在此， 溢流管1 〇，是在貯水部8內且位於左右的隔間壁6的後方 的兩支溢流管10所構成。 更進一步，在溢流管10的下方，一體地被連設有用 來朝向下方引導進入至溢流管10的植栽用水W的排水管 11° 另一方面，在位於左右中央的隔間壁6的後方，以上 下地貫通後方底壁3a的狀態之下，一體地設有用來引導 下述的植栽用水汲取用的供水軟管H2的引導筒1 3。 在互相地前後方向相鄰接的隔間壁6與溢流管10之 間，是具有與溢流管10同等高度的方式，藉由從後方底 壁3a被豎設的板狀第1增強肋部19a被連結。 又，在互相地前後方向相鄰接的隔間壁6與引導筒1 3 之間，是藉由板狀第2增強肋部19b所連結。更進一步， 引導筒1 3是與引導筒1 3最接近的長側壁4的部位之間， 也具有引導筒13同等的高度的方式，藉由朝向前後方向 延伸的板狀第3增強肋部1 9c所連結。 引導筒13與後方的長側壁4之間是藉由第3增強肋 部1 9c被隔開之故，因而在被形成於引導筒1 3與隔間壁6 之間的第2增強肋部1 9 b，形成有容許位於引導筒1 3左右 的兩個單位植栽用空間2 a之間的植栽用水w來往的缺口 1 9 p ° 缺口 19p最下端的局度是大約7〜8mm，設定成充分 -11 - 201244626 地低於溢流管10的高度（大約14mm)。 又，代替被形成於第2增強肋部19b的缺口 19p，於 第3增強肋部19c的下端附近設置容許位於引導筒13左 右的兩個單位植栽用空間2a之間的植栽用水W可往來的 缺口也可以。 爲了可以上下地積疊複數植栽容器1彼此的方便性， 各隔間壁6的上邊緣，做成對應於底壁3之傾斜的傾斜上 邊緣6a。 以同樣之目的，在底壁3的周部設有嵌合用階段部3s ，而在短側壁5的上邊緣設有凹入部14:該凹入部14是 嵌入有設於短側壁5的下邊緣的圓形柱狀體12a» 亦即，如第4圖所示地，上下地累積植栽容器1之際 ，位於上方的植栽容器1的底壁3下面，設定成抵接於位 在下方的植栽容器1的隔間壁6的傾斜上邊緣6a » 更進一步，大約與上述的抵接同時地，位於上方的植 栽容器1的底壁3的階段部3s，設定成嵌入於位於上方的 植栽容器1的上面開口部，又，柱狀體12a設定成嵌入於 凹入部1 4。 在可載置於位在最上方的植栽容器1的上面開口部的 蓋構件la，設有嵌入於短側壁5的凹入部14的凸部15。 又，在蓋構件la下面，也設置引導構件16，該引導 構件16是用來適當地保持供水軟管H2的前端部（或是， 安裝於該前端部附近的分岐接頭J2)的方向，尤其是，左 右方向。 -12- 201244626 更進一步，設於短側壁5的下邊緣的柱狀體12a，是 視需要，也可利用做爲從側面供應植栽用水W的手段° 這時候，於封鎖該柱狀體12a內部的壁構件形成貫通 孔，並於該貫通孔連接植栽用水汲取用的軟管就可以。 如第1圖所示地，將複數層的植裁容器1藉由各部分 的嵌合來連結被配置於室內等的底面的器殼lc上，並以 配置於器殼內部的形態可實施可儲備供水於各植裁容 器1所用的植栽用水w的植栽用水槽1 b ° 在表示於第1圖的例子中，器殼lc與植栽容器1之 間共通化俯視觀看的輪廓形狀’且於植栽用水槽1 b的內 部設匱泵浦30，做爲植栽裝置整體在外觀上成爲簡單又優 異者。 從各植栽容器1的溢流管10等所排水的多餘植栽用 水w，是經由被連接於最下層的溢流管10下方的排水管 11，及被外嵌於排水管11下端的排水軟管H3被回收在植 栽用水槽lb。更進一步，溢流管10及排水管11的內徑是 做爲大約14mm至15mm。 被回收在植栽用水槽lb的植栽用水W，是經由連接 著泵浦30之出口與設置於植栽用水槽lb上面的接頭J1 的槽內軟管H1，及由接頭Π經由各引導筒13朝向上方 被引導的供水軟管H2，以被供應於最上層的植栽容器1 的形式能夠不浪費地使用。 供水軟管H2的前端是藉由分岐接頭〗2被分岐成兩支 管，大約均等地被供應於最上層的植栽容器1左右的單位 -13- 201244626 貯水部8 a » 各植栽底材A，是以浸漬於單位貯水部8 用水W的狀態之下載置其下部。因此，各植荣 面吸取植栽用水W，一面將植栽用水W供應ί 根R並可予以植栽。 如上所述地，載置植栽底材Α的前方底昼 成於具有各單位植栽用空間2a的大約開口部 且愈由開口部遠離的一側愈位於下方的傾斜角 〇 因此，如第2圖所示地，植栽底材A，是 口部遠離的一側愈浸漬於植栽用水W內，而 稍微浸漬於植栽用水W、或是視情形成爲未浸 水W。 結果，可大大地確保植物P的根圈（植物, 可伸長的區域），且對於其根圈供應有充分量 W之故，因而可確保植物的良好生育。 (排水部的構造） 如第3圖至第10圖所示地，在貯水部8 有以較短時間用來將殘留在貯水部8的植栽用 排水的排水部 20a' 20b ' 20c、 20d、 20e、 20f 因此，在泵浦30所導致的對於貯水部8 的時機，未吸水於植栽底材A且留在貯水部8 W > 是藉由排水部 20a > 20b、 20c、 20d、 20e、 a內的植栽 底材A — 令植物P的 I 3 b，被形 側位於上方 α的傾斜面 成爲愈由開 開口部側僅 漬於植栽用 之根R生長 的植栽用水 的底面，設 水W予以 3 之供水終了 的植栽用水 2 0 f被排出 -14- 201244626 之故，因而不會長時間被置放於貯水部8。其結果’在植 栽底材A或是植栽用水W很難發生害蟲或黴菌、其他的 微生物。 排水部20a、20b、20c、20d、20e、20f都形成能夠連 通貯水部8的底面與排水管1 1的內面。 構成各扫，7]<部 20a、 20b、 20c、 20d、 20e、 20f 的孑L 之 內徑或是縫隙之間隙尺寸，是設定成排水部所具有的排水 能力是低於泵浦3 0之供水速度。 因此，泵浦30所導致的對於貯水部8之供水中，是 以10mm以上等的適當高度把植栽用水W保持在貯水部8 之故，因而植栽底材A是以適當的效率吸取植栽用水W， 而能夠出現保水之狀態。 又，構成 水部 20a 、 20b 、 20c 、 20d 、 20e 、 20f 的孑L 之內徑或縫隙之間隙尺寸，是被設定成具有藉由含於植栽 用水W的粒子狀或纖維狀等的異物不容易閉塞排水部20a 、20b、20c、20d > 20e、20f 的適當大小。 (第1實施形態） 由第3圖至第5圖的第1實施形態所成的排水部20a ，是呈被形成於溢流管1 0側面的一個貫通孔狀，該貫通 孔是朝向溢流管1 0的徑方向延伸，而該貫通孔的下端位 置，是與貯水部8底面的水準一致。在此，排水部20a的 內徑是大約做爲5 m m。 更具體而言，如第5 ( a )圖所示地，構成溢流管1〇 -15- 201244626 的圓筒狀部位的一部分，在俯視觀看藉由具備朝向徑方向 內側突出的反方向的圓弧狀的凹狀壁部1 〇a所構成，排水 部20a是以橫向地貫通形成於該凹狀壁部10a的下端的形 式.，連通貯水部8的底面與排水管1 1的內面。 在排水部20a的上游側端部的側方，設有朝向徑方向 外方向突出的左右一對的異物捕捉凸部21a。如第5(a) 圖所示地，異物捕捉凸部2U是在後方底壁3a的上面與 凹狀壁部l〇a的外周面交叉的位置呈具有中心的局部球面 狀。 凹狀壁部1 〇a，是在俯視觀看具備比溢流管1 0全周的 四分之一稍微少的周長，配置成面臨於最左右外側的單位 植栽用空間2a，靠近其前方的端部是配置成鄰接於第1增 強肋部1 9 a。 結果，左右一對的各排水部20a，是在俯視觀看成爲 朝向後方向且朝向左右的內側延伸的形態。 排水部20a是對於垂直方向呈角度的方式，在此大槪 朝向水平方向延伸之故，因而由排水部20a所排出的植栽 用水W的大部分是如第5(b)圖所示地，基本上愈到下 方一面描繪由凹狀壁部l〇a朝向橫方向離開的拋物線一面 掉落，並不是到達至位於下方的另一植栽容器1的溢流管 10的內部，而是到達至溢流管1〇以外的後方底壁3a。 (第2實施形態） 在例示於第6圖的植栽容器1，於構成溢流管10的圓 -16- 201244626 筒狀部位的一部分形成有平板狀壁部10b’而於該平板狀 壁部1 〇b設有排水部20b。 平板狀壁部l〇b，是面臨於最左右外側的單位植栽用 空間2 a的開口部’且在俯視觀看對於第1增強肋部1 9 a 呈傾斜。 排水部20b，是以朝向橫方向形成於平板狀壁部10b 的下端的貫通孔的形態’連通貯水部8的底面與排水管1 1 的內面。 更進一步，在平板狀壁部10b的徑方向一側的一面， 朝向上下方向地形成有與排水部20b的內徑同等寬度的溝 部 1 0d。 在此，對於溝部l〇d朝向徑方向外所突出的左右平板 狀壁部10b的部位的下端附近構成異物捕捉凸部21b。 在此，排水部20b，由於大致朝向水平方向延伸之故 ，因而由排水部20b所排出的植栽用水W的大部分是如 第6(b)圖所示地，基本上愈到下方一面描繪由平板狀壁 部10b朝向橫方向離開的拋物線一面掉落，並不是到達至 位於下方的另一植栽容器1的溢流管1 0的內部，而是到 達至溢流管10以外的後方底壁3a。 (第3實施形態） 在例示於第7圖的植栽容器1，構成溢流管10的圓筒 狀部位的一部分，在俯視觀看藉由突出於徑方向內側的拱 形壁部10c所形成。 -17- 201244626 與第1及第2實施形態不相同，該排水部2〇c並不是 拱形壁部1 〇c的一部分’而是沿著位於拱形壁部1 〇c的徑 方向最內側的頂部的方式，對於後方底壁3 a以朝向上下 方向的貫通孔的形態，連通貯水部8的底面與排水管11 的內面。 排水部20c是被形成於比溢流管1 〇的基本上的外側 面還位於朝向徑方向內側引退的位置。在此，對於排水部 20c朝向徑方向外方所突出的左右溢流管10的外周面的下 端附近構成異物捕捉凸部21c。 由排水部20c所排出的植栽用水W的大部分是如第7 (b )圖所示地，掉落排水管1 1的內部，而到達至位於下 方的另外植栽容器1的溢流管10的內部或是到達至溢流 管10以外的後方底壁3a。 在例示於第7圖的形態的植栽容器1中，排水部20c 與長側壁4、短側壁5、隔間壁6等相同朝向上下方向延 設。 因此，藉由樹脂的射出成形用來製作植栽容器1之際 ，將成形排水部20c所用的凸部設置於被上下地分割的兩 件金屬模（未圖示），在植栽容器1之成形時’就可同時 成形排水部20c。 (第4實施形態） 被設置於例示於第8圖的植栽容器1的排水部20d， 是具備被形成於構成溢流管10的圓筒狀部位的周方向的 -18- 201244626 一部分的縱縫隙的形態。 該縱縫隙是溢流管10的全長全面朝向上下方向延伸 ，並連通貯水部8的底面與排水管11的內面。 由該縫隙狀的排水部20d所排出的植栽用水W的大 部分是如第8 ( b )圖所示地，掉落在排水管1 1的內部， 而到達至位於下方的另一植栽容器1的溢流管10的內部 或是到達至溢流管10以外的後方底壁3a。 在例示於第8圖的形態的植栽容器1中，從縱縫隙狀 的排水部20d也與長側壁4、短側壁5、隔間壁6等相同 朝向上下方向延設。 因此，藉由樹脂的射出成形用來製作植栽容器1的成 形排水部20d所用的凸部設置於被上下地分割的兩件金屬 模（未圖示），在植栽容器1之成形時，就可同時成形排 水部2 0 d。 (第5實施形態） 在例示於第9圖的植栽容器1中，溢流管1〇是呈單 純的圓筒形，排水部20d，是與第1增強肋部19a的外側 面鄰接的方式，以朝向橫方向形成於溢流管1 〇的下端的 貫通孔的形態，連通貯水部8的底面與排水管Π的內面 〇 該排水部20e是大槪朝向水平方向延伸之故’因而由 排水部20e所排出的植栽用水W的大部分是如第9 ( b ) 圖所示地，基本上愈到下方一面描繪由第1增強肋部1 9a -19- 201244626 朝向橫方向離開的拋物線一面掉落，並不是到達至位於下 方的另外植栽容器1的溢流管10的內部，而是到達至溢 流管10以外的後方底壁3a。 (第6實施形態） 在例示於第10圖的植栽容器1中，在各隔間壁6的 下部，有在橫方向流通各單位貯水部8a彼此間的連通路9 大槪矩形的缺口狀所形成。 排水部20f，是呈被形成於溢流管1 0側面的一個貫通 孔狀，該貫通孔是朝向溢流管1 〇的徑方向延伸，其內徑 是大約做爲3 m m » 如第10(b)圖所示地，該貫通孔的下端的位置，是 由構成貯水部8的實質上底面的中央底壁3c的上面設定 成高5mm的水準。此爲用來更抑制排水部20f藉由含有於 植栽用水W的粒子狀或纖維狀等的異物被閉塞的情形。 如第6 ( a )圖及第6 ( b )圖所示地，構成溢流管1 〇 的圓筒狀部位的一部分（比對應的隔間壁6更接近中央的 前方部位），大致藉由與長側壁4平行地延伸的平板狀壁 部1 〇b所形成。 排水部20f，是朝向前後方向貫通形成於該平板狀壁 部1 Ob的下端的形式，連通貯水部8的底面與排水管1 1 的內面。 在排水部20f的左右側方及下方，設有朝向徑方向外 方突出的異物捕捉凸部21d。異物捕捉凸部21d是特別地 -20- 201244626 在排水部20f的左右側方大致呈朝向前方突出的局部球面 狀。 排水部20f，是對於垂直方向呈角度的方式，在此， 大致朝向前後水平方向延伸之故，因而由排水部20f所排 出的植栽用水W的大部分，是基本上愈到下方一面描繪 由平坦壁部1 〇 b朝向後方向離開的拋物線一面掉落，並到 達至位於下方的植栽容器1本體的溢流管10以外的貯水 部8或是植栽底材A。 更進一步，在該實施形態，具備：後方底壁3a、及中 間縱壁3d ;該後方底壁3a是由長側壁4的下端朝向前方 斜下方地延伸，該中間縱壁3 d是由後方底壁3 a的下端朝 向下方大槪水平的中央底壁3c而大致與長側壁4平行地 延伸。排水部20f是有關於上下方向配置於該中間縱壁3d 的中間附近之水準。 如第10(a)圖及第10(b)圖所示地，在比溢流管 1〇的上端更上方，設有遮蔽板24。 遮蔽板24，是一抑制手段；該遮蔽板24是抑制由溢 流管1 〇的上端或是排水部20f進入溢流管1 0內，並由排 水管1 1所流下的植栽用水W，未能供應於下方的植栽容 器1的貯水部8而進入溢流管1 0的手段。 遮蔽板24，是由左右兩個隔間壁6外側的各側面’與 溢流管10的軸心交叉，且在平面觀看覆蓋溢流管1〇的開 口部之大部分的方式朝向橫方向地突出形成。 在溢流管1 〇的上端部中，由相當於與隔間壁6之境 -21 - 201244626 界的前後的兩個部位，有一對連接部25朝向遮蔽 上方延伸，且與遮蔽板24的前端及後端平滑地被

Description of the Invention: [Technical Field] The present invention relates to a planting device comprising: a planting container, a water-absorbing planting substrate, and a water supply means; the planting container is provided with: a reserve The water storage part for planting water; the water-absorbing planting substrate is disposed in the water storage part: the water supply means is to supply the planting water to the water storage part, and the overflow pipe for draining the planting water exceeding a predetermined height is provided in the water storage part Water storage department. [Prior Art] The prior art document information relating to this planting device is shown in Patent Document 1 below. In the planting device of the patent document 1, the planting water is supplied to the water storage part of the planting vessel by a water supply means such as a pump, and the planting can be carried out without exceeding the level of the upper end of the overflow pipe. Water is stored in the water storage department. A part of the planting substrate that is immersed in the planting water for planting is used to extract the planting water, and the appropriate amount of planting water is kept inside, so that the plant planted on the planting substrate can be appropriately cultivated. . When the planting water having a water absorption capacity exceeding the water-absorbing capacity of the planting substrate is supplied, or when the supply speed of the planting water caused by the water supply means exceeds the water absorption speed of the planting substrate, the excess planting water is overflowed. The tube is drained. In particular, when a plurality of planting containers are used up and down, the planting water discharged from the overflow pipe is supplied as a planting container provided below, and finally the planting base of all the planting containers is accumulated. The material will absorb the required amount of water for planting. -5- 201244626 In addition, the planting water that is drained from the overflow pipe of the planting container in the lowermost part is recycled to a suitable water storage container, and can be used as the next irrigation plant if necessary. Use water. Patent Document 1: Japanese Laid-Open Patent Publication No. 2009-45015 (paragraph No. 0021, FIG. 2) [Summary of the Invention] However, in the most commonly used method, in order to sufficiently absorb water on a planting substrate, in a planting container The water storage unit supplies a sufficient amount of water for planting water that exceeds the water absorption capacity of the plant substrate. In this case, in the planting apparatus described in Patent Document 1, there is a possibility that a certain amount of planting water is placed for a long period of time from the upper end of the overflow pipe, and if the planting water is placed for a long period of time, Therefore, the object of the present invention is to provide a planting device which is even in the water storage portion of the planting container in view of the problems given by the prior art planting device exemplified above. Planting water that supplies more water than the water-absorbing capacity of the planting substrate does not impair the suppressor of aesthetics. The planting apparatus according to the present invention is characterized in that it comprises: a planting container, and a water supply means: the planting container is provided with: a water storage part capable of storing planting water and a plant capable of carrying water absorption a planting space for the substrate; the water supply means is for supplying the planting water to the water storage portion, and an overflow pipe for draining the planting water exceeding a predetermined height is provided in the water storage portion, and is disposed on the bottom surface of the water storage portion There is a drain portion, and the drainage capacity of the drain portion 201244626 is lower than the water supply speed of the water supply means. In the planting device of the above-described characteristic configuration, the drain portion having the drainage capacity lower than the water supply speed of the water supply means is provided on the bottom surface of the water storage portion, and therefore, the water supply of the water storage portion due to the water supply means is terminated. The planting water that has not been absorbed in the planting substrate and remains in the water storage portion is drained by the drain portion. Therefore, it is possible to prevent the planting water from being placed in the water storage part for a long time, and no mold occurs in the planting substrate, or the pests occur in the planting water, etc., and the appearance is not impaired. Further, since the drainage capacity of the drainage portion is lower than the water supply speed of the water supply means, the planting water is held in the water storage portion at an appropriate height in the water supply to the water storage portion due to the water supply means, and thus the planting bottom is planted. The material is suitable for absorbing water of the planting water, and can be in a state of retaining water. According to still another aspect of the present invention, a drain pipe that communicates with the overflow pipe is formed to protrude downward from the water storage portion, and the drain portion is formed to communicate a bottom surface of the water storage portion and an inner surface of the drain pipe. Its characteristics. For example, when the drainage portion is formed at a different position from the position where the overflow pipe or the drain pipe is formed, even if the drainage of the unnecessary planting water can be performed, the planting water entering the drainage portion is formed along the lateral direction to form the storage water. Since the bottom wall member of the bottom surface of the bottom portion is easily moved under the bottom wall member, there is a problem in that the bottom wall member is soiled under the same movement, or the boundary of the planting container accumulated up and down is oozing out to the outside. However, in the case of the present structure, the planting water entering the drain portion is first moved downward along the inner surface of the drain pipe which protrudes downward from the water storage portion, and falls from the lower end of the drain pipe, and generally becomes It is sure to reach the water storage part of the planting container of the lower stage or the surface of the planting substrate. In addition, in the case of the structure, the planting water that is drained from the drain portion of the planting container at the lower end can be used as compared with the structure in which the planting water entering the drain portion moves downward along the outside of the drain pipe. It is reliably recovered into a suitable tank by a hose or the like which is externally fitted to the drain pipe. According to still another feature of the present invention, the drain portion is formed to extend in an angular direction in a vertical direction. In the case of the present structure, the planting water that is drained downward from the drain portion by its own weight is dropped from the immediately below the drain portion to the position displaced to the side. Therefore, it is set at the lower layer. The planting substrate of the planting container is ideal for being filled with water. According to another feature of the present invention, the foreign matter capturing convex portion for capturing foreign matter contained in the planting water is provided on the side of the drain portion, and is characterized by the foreign matter. In the case of the present structure, even if foreign matter floats in the water surface of the planting water stored in the water storage portion, in the water or in the vicinity of the bottom surface of the water storage portion, most of the foreign matter is captured by the foreign matter capturing convex portion. By the foreign matter, the drain portion is not easily occluded, and the normal draining state can be ensured. [Embodiment] Hereinafter, a mode for carrying out the invention will be described with reference to the drawings -8 · 201244626 as shown in Fig. 1 The planting device according to the present invention includes: a planting container 1, and an electric pump, etc. (an example of a water supply means): the planting container 1 is provided with a water storage portion 8 for storing planting water W; The pump 30 supplies the planting water W to the water storage unit 8.

At this time, the columnar body 12a is blocked. The inner wall member is formed with a through hole, and a hose for picking up the planting water is connected to the through hole. As shown in Fig. 1, the plurality of planting containers 1 are connected to the casing lc disposed on the bottom surface of the room or the like by fitting the respective portions, and can be disposed in the inside of the casing. In the example shown in Fig. 1, in the example shown in Fig. 1, the contour shape of the bird's-eye view container 1 is shared with the planting container 1 in a plan view. In addition, the pumping unit 30 is provided in the interior of the planting water tank 1b, and it is simple and excellent in appearance as a whole planting device. The excess planting water w that is drained from the overflow pipe 10 of each of the planting containers 1 is drained through the drain pipe 11 connected to the lowermost overflow pipe 10, and is drained to the lower end of the drain pipe 11 The hose H3 is recovered in the planting tank lb. Further, the inner diameters of the overflow pipe 10 and the drain pipe 11 are made to be about 14 mm to 15 mm. The planting water W to be recovered in the planting tank lb is an in-tank hose H1 connected to the outlet of the pump 30 and the joint J1 provided on the planting tank lb, and the joints are passed through the respective guide cylinders. The water supply hose H2 that is guided upward toward the top can be used without waste in the form of the planting container 1 supplied to the uppermost layer. The front end of the water supply hose H2 is divided into two tubes by a split joint 〗 2, and is equally supplied to the unit of the uppermost planting container 1 - 13 - 201244626 Water storage part 8 a » Each planting substrate A In the state where the unit water storage unit 8 is immersed in the water W, the lower portion is placed. Therefore, each planting surface absorbs the planting water W, and the planting water W is supplied to the root R and can be planted. As described above, the front bottom of the planting substrate Α is formed in an inclined angle having a lower opening portion of each unit planting space 2a and a side closer to the opening portion than the opening portion. As shown in Fig. 2, the planting substrate A is immersed in the planting water W as the side away from the mouth, and is slightly immersed in the planting water W or, as the case may be, not soaked in water W. As a result, the root ring (plant, extensible region) of the plant P can be greatly ensured, and a sufficient amount of W is supplied to the root ring, thereby ensuring good fertility of the plant. (Structure of the Drainage Section) As shown in Figs. 3 to 10, the water storage portion 8 has a drain portion 20a' 20b ' 20c, 20d for draining the planting drainage water remaining in the water storage portion 8 for a short period of time. 20e, 20f Therefore, the timing of the water storage unit 8 caused by the pump 30 is not absorbed by the planting substrate A and remains in the water storage portion 8 W > by the drainage portion 20a > 20b, 20c, 20d Planting substrate A in 20e, a - I 3 b of plant P, the inclined surface of the upper side of the shaped side is the planting water which grows only by the root R of the planting side. In the bottom surface, the planting water 20 0 f, which is set by the water supply to the water supply, is discharged from -14 to 201244626, and thus is not placed in the water storage portion 8 for a long time. As a result, it is difficult to cause pests or molds and other microorganisms in the planting substrate A or the planting water. The drain portions 20a, 20b, 20c, 20d, 20e, and 20f are each formed to be connectable to the bottom surface of the water storage portion 8 and the inner surface of the drain pipe 1 1. The inner diameter of the 孑L of each of the sweeps, 7]<sections 20a, 20b, 20c, 20d, 20e, 20f or the gap size of the slits is set such that the drainage capacity of the drain portion is lower than the pump 3 0 The speed of water supply. Therefore, in the water supply to the water storage unit 8 caused by the pump 30, the planting water W is held in the water storage unit 8 at an appropriate height of 10 mm or more, and the planting substrate A is sucked at an appropriate efficiency. Planting water W, and the state of water retention can occur.

It is not easy to occlude the appropriate size of the drain portions 20a, 20b, 20c, 20d > 20e, 20f. (first embodiment) The drain portion 20a formed in the first embodiment of the third to fifth embodiments is formed in a through hole shape formed on the side surface of the overflow pipe 10, and the through hole is directed toward the overflow. The pipe 10 extends in the radial direction, and the lower end position of the through hole coincides with the level of the bottom surface of the water storage portion 8. Here, the inner diameter of the drain portion 20a is approximately 5 m. More specifically, as shown in Fig. 5(a), a part of the cylindrical portion constituting the overflow pipe 1〇-15-201244626 is a circle having a direction opposite to the inner side in the radial direction in plan view. The arc-shaped concave wall portion 1 〇a is formed, and the drain portion 20a is formed to penetrate the lower end of the concave wall portion 10a in a lateral direction. The bottom surface of the water storage portion 8 and the inner surface of the drain pipe 11 are connected. On the side of the upstream side end portion of the drain portion 20a, a pair of left and right foreign matter catching convex portions 21a projecting in the radial direction direction are provided. As shown in Fig. 5(a), the foreign matter capturing convex portion 2U has a partial spherical shape having a center at a position where the upper surface of the rear bottom wall 3a intersects with the outer peripheral surface of the concave wall portion 10a. The concave wall portion 1 〇a has a circumference slightly smaller than a quarter of the entire circumference of the overflow pipe 10 in a plan view, and is disposed so as to face the unit planting space 2a on the outermost left side, and is adjacent to the front side The end portion is disposed adjacent to the first reinforcing rib portion 19a. As a result, each of the pair of right and left drain portions 20a is formed to extend in the rearward direction and toward the left and right sides in plan view. The drain portion 20a is angled in the vertical direction, and since the large sill extends in the horizontal direction, most of the planting water W discharged from the drain portion 20a is as shown in Fig. 5(b). Basically, the lower side of the parabola that is drawn away from the concave wall portion 10a toward the lateral direction is dropped, and does not reach the inside of the overflow pipe 10 of the other planting container 1 located below, but reaches The rear bottom wall 3a other than the overflow pipe 1〇. (Second Embodiment) In the planting container 1 illustrated in Fig. 6, a flat wall portion 10b' is formed in a part of a cylindrical portion of a circle -16, 201244626 constituting the overflow pipe 10, and the flat wall portion 10b is formed in the flat plate portion 1 〇b is provided with a drain portion 20b.

Further, on one side in the radial direction of the flat wall portion 10b, a groove portion 10d having the same width as the inner diameter of the drain portion 20b is formed in the vertical direction. Here, the foreign matter capturing convex portion 21b is formed in the vicinity of the lower end portion of the portion of the left and right flat wall portion 10b in which the groove portion 10d is protruded outward in the radial direction. Here, since the drain portion 20b extends substantially in the horizontal direction, most of the planting water W discharged from the drain portion 20b is substantially lower as shown in Fig. 6(b). The parabola which is separated from the lateral direction by the flat wall portion 10b is dropped, and does not reach the inside of the overflow pipe 10 of the other planting container 1 located below, but reaches the rear bottom other than the overflow pipe 10.

The inside of the overflow pipe 10 of the container 1 reaches the rear bottom wall 3a other than the overflow pipe 10. In the planting container 1 of the embodiment shown in Fig. 8, the vertical slit-shaped drain portion 20d is also extended in the vertical direction as the long side wall 4, the short side wall 5, the partition wall 6, and the like. Therefore, the convex portion for forming the molded drain portion 20d of the planting container 1 by the injection molding of the resin is provided in two metal molds (not shown) that are vertically divided, and when the plant container 1 is formed, The drain portion 20 d can be formed at the same time. (Fifth Embodiment) In the planting container 1 illustrated in Fig. 9, the overflow pipe 1 is a simple cylindrical shape, and the drain portion 20d is adjacent to the outer surface of the first reinforcing rib 19a. In the form of a through hole formed at the lower end of the overflow pipe 1 朝向 in the lateral direction, the bottom surface of the water storage portion 8 and the inner surface of the drain pipe 〇 are connected, and the drain portion 20e extends in the horizontal direction. Most of the planting water W discharged from the drain portion 20e is as shown in Fig. 9(b), and the parabola which is separated from the first reinforcing rib 1 9a -19- 201244626 in the lateral direction is substantially drawn downward. When it is dropped, it does not reach the inside of the overflow pipe 10 of the other planting container 1 located below, but reaches the rear bottom wall 3a other than the overflow pipe 10. (sixth embodiment) In the planting container 1 shown in Fig. 10, in the lower portion of each of the partition walls 6, there is a gap shape in which the communication passages 9 between the unit water storage portions 8a are distributed in the lateral direction. Formed. The drain portion 20f is formed in a through hole shape formed on the side surface of the overflow pipe 10, and the through hole extends in the radial direction of the overflow pipe 1 ,, and the inner diameter thereof is approximately 3 mm » as in the 10th ( b) As shown in the figure, the position of the lower end of the through hole is set to a level of 5 mm higher by the upper surface of the center bottom wall 3c constituting the substantially bottom surface of the water storage portion 8. This is a case where the foreign matter such as particles or fibers contained in the planting water W is blocked from being blocked. As shown in Fig. 6(a) and Fig. 6(b), a part of the cylindrical portion constituting the overflow pipe 1〇 (closer to the center than the corresponding partition wall 6) is substantially The flat wall portion 1 〇b extending in parallel with the long side wall 4 is formed. The drain portion 20f is formed so as to penetrate the lower end of the flat wall portion 1 Ob in the front-rear direction, and communicates with the bottom surface of the water storage portion 8 and the inner surface of the drain pipe 1 1 . The foreign matter capturing convex portion 21d that protrudes outward in the radial direction is provided on the left and right sides and the lower side of the drain portion 20f. The foreign matter capturing convex portion 21d is, in particular, a partial spherical shape that protrudes forward in the left and right sides of the drain portion 20f in particular, -20-201244626. The drain portion 20f has an angle with respect to the vertical direction. Here, since it extends substantially in the front-rear horizontal direction, most of the planting water W discharged from the drain portion 20f is substantially lower than the lower side. The parabola in which the flat wall portion 1 〇b is separated toward the rear direction is dropped, and reaches the water storage portion 8 other than the overflow pipe 10 of the main body of the planting container 1 located below or the planting substrate A. Furthermore, in this embodiment, the rear bottom wall 3a and the intermediate vertical wall 3d are provided. The rear bottom wall 3a extends obliquely downward from the lower end of the long side wall 4, and the intermediate vertical wall 3d is from the rear bottom. The lower end of the wall 3a extends toward the lower horizontal central bottom wall 3c and extends substantially parallel to the long side wall 4. The drain portion 20f is at a level that is disposed in the vicinity of the middle of the intermediate vertical wall 3d in the vertical direction. As shown in Figs. 10(a) and 10(b), a shielding plate 24 is provided above the upper end of the overflow pipe 1〇. The shielding plate 24 is a suppressing means; the shielding plate 24 is for inhibiting the planting water W flowing from the upper end of the overflow pipe 1 or the drainage portion 20f into the overflow pipe 10 and flowing down by the drain pipe 1 The means for supplying the water storage portion 8 of the planting container 1 below and entering the overflow pipe 10 is not provided. The shielding plate 24 is formed such that each side surface 'on the outer side of the left and right partition walls 6 intersects with the axial center of the overflow pipe 10, and faces most of the opening portion covering the overflow pipe 1〇 in a plan view. Prominent formation. In the upper end portion of the overflow pipe 1 ,, a pair of connecting portions 25 extend toward the upper side of the shield and at the front end of the shielding plate 24 at two positions corresponding to the front and rear of the boundary 21 - 201244626 of the partition wall 6 The rear end is smoothly further extended, and the thin plate-shaped guide wall portion 26 is erected upward except for the connection portion 25 of the shield plate 24. As a result, the upper surface of the 24 is a groove-shaped flow path which is extended after the partition wall 6 and the guide wall portion 26 are sandwiched. In other words, the planting water w that flows from the upper end water portion 20f of the overflow pipe 10 of the planting container 1 above the drain pipe 1 is directed toward the overflow, and most of the water is also received by the upper surface of the shielding plate 24, and is The guide wall 26 is guided, and is supplied to the water storage portion 8 by the outer circumference of the name or the like along the front and rear connection portions 25. Therefore, the drain pipe 11 of the body of the planting container 1 does not directly enter the inner surface of the overflow pipe 10 by the planting water. The excess planting water W accumulated in the water storage portion 8 is from the upper end of the overflow pipe 10 and the opening portion Q of the lower surface of the shield plate 24 to the inside of the overflow pipe 110.
