201032884 、以及以覆蓋住該殼體7的開口的方式與其結合的蓋子8 ，在兩者的結合狀態下係呈現略圓筒狀的外形。淨水濾芯 6係以該圓筒的中心軸A X (請參考第1圖和第2圖）沿 著上下方向的姿勢來被使用。此外，在以下的說明當中， 係以在使用狀態時的淨水濾芯6的圓筒形狀作爲基準，來 規定上下方向、軸方向、周方向以及徑向。 殼體7係具備：略圓形狀的底壁部13、以及從該底 壁部13的外周豎立的周壁部14。在殼體7內，充塡著例 如：活性碳或離子交換樹脂等的淨化劑1 5。藉由該殼體7 的底壁部13以及周壁部14和蓋子8來形成用來收容淨化 劑1 5的淨化室S 1。 在底壁部13的略中央部份係設有一孔13a係用來將 被導入到淨化室S1內的水從排水口 7 c排出。在底壁部 1 3的孔1 3 a係連設著一個與排水口 7c相連通的大直徑部 16，在本實施方式中，這個大直徑部16的內部係可作爲 添加劑收容室S2用來收容著例如：鈣質之類的添加劑20 。添加劑2 0例如：是收容在孔徑被設定成小於該添加劑 2 0的粒徑的透水性的袋構件內之後才設置在添加劑收容 室S2內。並且在大直徑部16的下端係連設著小直徑部 1 7，係在該小直徑部1 7設置排水口 7 c。 又，在殼體7內，係有一個多孔質板片18被壓入到 該殼體7的下方而設在該處。多孔質板片18是用來防止 :淨化劑1 5洩漏到添加劑收容室S 2。多孔質板片1 8之 被形成在該板片上的細孔的口徑係小於淨化劑1 5的粒徑 -12- 201032884 ，而淨化劑15係被充塡在這個多孔質板片18之上。 此外，在本實施方式中，係在殼體7的底壁部13係 局部地突設有數個從淨水濾芯6的中心軸Αχ呈放射狀延 伸的凸部19，而多孔質板片18則是被這些凸部19所支 撐而保持成底部上抬的狀態。因爲多孔質板片18被保持 成底部上抬的狀態，所以被導入到淨化室S1的水將會略 全面地從多孔質板片18往下流動，因此，與多孔質板片 φ 1 8被設置成未受到底壁部1 3的凸部1 9所上抬的情況比 較之下，水的流動得以更爲順暢。此外，亦可將底壁部 1 3形成例如：朝添加劑收容室S2傾斜。這種情況係可使 得水流更加順暢。 在周壁部14的上端部係設有可與蓋子8嵌合的突起 14a。將該突起14a嵌合到蓋子8的凸緣部22上的凹溝 22a，即可將殻體7與蓋子8結合成液密狀態。 蓋子8係具備：形成有導水口 8a的基底部21。如第 Ο 3圖所示，導水口 8a係形成略呈矩形，沿著基底部2 1的 外周部設有複數個（在本實施方式中係設有6個）。並且 在導水口 8a係利用例如：內插成型等方式張設有與蓋子 8 —體成型的透水性的過濾構件2 5，該過濾構件2 5的孔 徑係小於淨化劑1 5的粒徑，用以防止淨化劑1 5的洩漏。 又，在本實施方式的蓋子8上係設有一個從基底部 21朝上方突出的突出部23。在突出部23形成有空氣釋出 通路。在淨水濾芯6內如果有空氣不經意地累積的話，將 會因水的重力與空氣的浮力的互相拉扯而導致水的流路受 -13- 201032884 空氣所堵塞，因此將變成無法獲得所期望的流量’想要獲 得淨水係會產生需要花費很多時間的虞慮。因此’本實施 方式中係大致沿著淨水濾芯6的中心軸Αχ來設置突出部 23，並在這個突出部23的上端部設置空氣釋出孔30。 根據這種結構，係可利用形成在蓋子8上的空氣釋出 孔30來讓累積在淨水濾芯6內的空氣逃逸釋出。又，因 爲是利用突出部23使得空氣釋出孔30係設在較之導水口 8a更高的位置處，因此可利用空氣釋出孔30與導水口 8a φ 之間的壓力差，有效地將淨水濾芯6內的空氣推出到外部 ，而得以順暢地將水導入到淨水濾芯6的淨化室S1內。 此外，空氣釋出孔30與導水口 8a之間的高低差是以設成 5mm以上爲宜。設成1 0 mm以上更佳。 在空氣釋出孔30，也是與導水口 8a同樣地，利用例 如：內插成型等方式張設有與蓋子8 —體成型的透水性的 過濾構件26，該過濾構件26的孔徑係小於淨化劑1 5的 粒徑，用以防止淨化劑1 5的洩漏。 0 如第3圖所示，在被形成有空氣釋出孔30的突出部 23上，係延伸形成有圓環狀的摘持部24。在殼體7的周 壁部14的外表面，係設有複數條沿著周方向的凸條27( 在本實施方式中係2條）。可藉由將凸條27卡合到被形 成在分隔壁體3的凹部3b上的突起3f，並且旋轉操作上 述摘持部24，即可將淨水濾芯6嵌裝到分隔壁體3的凹 部3b。此時，係將形成在底壁部13的外表面的密封部28 壓接在凹部3b的最底壁3c而結合成液密狀態，如此一來 -14 - 201032884 ，可以防止原水室4的原水不流入到淨水濾芯6內，反而 是漏出到淨化室5的情事。 如上所述，本實施方式的淨水濾芯6係具備：頂面呈 開口 ’並且內部被充塡了淨化劑15的殼體7、以覆蓋該 開口的方式與該殼體7相結合，而且被形成有導水口 8a 的蓋子8。又’在蓋子8上係形成有較之導水口 8a更高 位置的空氣釋出孔30。此外，在空氣釋出孔30以及導水 ® 口 8a係與蓋子8 —體成型設置有用來防止淨化劑15洩漏 到外部的過濾構件25。因此，原水的壓力損失係只有在 通過與過濾構件25 —體成型的導水口 8a時所產生的壓力 損失而已，所以可抑制水的阻力，並且因爲空氣釋出孔 3 〇係形成在較之導水口 8 a更高的位置，因此可利用導水 口 8a與空氣釋出孔30的壓力差而順暢地將水導入，進而 可提升淨水濾芯6的性能。 φ [第二實施方式] 其次，佐以第4圖和第5圖來說明本發明的第二實施 方式。 本實施方式的淨水濾芯係可替代上述第一實施方 式的淨水濾芯6 ’安裝到淨水器1來使用’用以結合到殼 體7的蓋子8A以及用以防止淨化劑15洩漏的過濾構件 33係與上述第一實施方式的淨水濾芯6的有所不同。 具體而言’本實施方式中，係在蓋子8A的基底部21 形成空氣釋出孔3 0A’將導水口 8a設在較之該空氣釋出 -15- 201032884 孔30A更低位置。 如第5圖所示，空氣釋出孔3 0A係沿著基底部21的 外周部設置複數個（本實施方式中係設置6個）。並且在 本實施方式中，突出部23A係從基底部21朝下方突出， 在突出部23A的下端部形成導水口 8b。 並且如第4圖所示，係在殼體7與蓋子8A之間，配 設有被設定成較之淨化劑1 5的粒徑更小的孔徑的透水性 的過濾構件33。具有可撓性的過濾構件33係安裝在殼體 φ 7的周壁部14的上端部，而將空氣釋出孔30A和導水口 8b加以覆蓋。過濾構件33係可由例如：不織布等來構成 〇 如上所述，本實施方式係利用突出部23A來將導水 口 8b設在較之空氣釋出孔30A更低的位置，所以係與上 述第一實施方式同樣地，可利用空氣釋出孔30A與導水 口 8b的壓力差，順暢地將水導入，進而可提升淨水濾芯 4 0的性能。 @ 此外，本實施方式的結構係將過濾構件33配設在殼 體7與蓋子8A之間，因爲可利用後加工來配設過濾構件 3 3，因此蓋子8 A的形狀所受到的約制很少，具有能夠擴 大設計上的自由度之優點。 [第三實施方式] 其次，佐以第6圖和第7圖來說明本發明的第三實施 方式。 -16- 201032884 本實施方式的淨水濾芯50係可替代上述第一、第二 實施方式的淨水濾芯6、40，安裝到淨水器1來使用’形 成於蓋子8B上的導水口 8c以及用來防止淨化劑15洩漏 的過濾構件43係與上述第二實施方式的淨水濾芯40的不 同。 具體而言，本實施方式係如第6圖所示，係在蓋子 8B的基底部21形成空氣釋出孔30A，並且將導水口 8c φ 設在較之該空氣釋出孔30A更低位置，而且將該導水口 8 c的口徑設定成小於淨化劑1 5。 如第7圖所示，空氣釋出孔3 0 A係沿著基底部21的 外周部設置複數個（在本實施方式中係設置6個）。在空 氣釋出孔30A利用例如：內插成型等方式張設有透水性 的過濾構件43，該過濾構件43的孔徑係小於淨化劑1 5 的粒徑，用以防止淨化劑1 5的洩漏。 又在本實施方式中，突出部23B係從基底部21朝下 Θ 方突出且設有複數個（在本實施方式中係設置3個），在 這個突出部23B的下端部係分別形成導水口 8c。導水口 . 8 c的口徑係形成小於淨化劑1 5的粒徑，如此一來，將可 防止淨化劑1 5的洩漏。 如上所述，本實施方式係利用突出部23B來將導水口 8c設在較之空氣釋出孔30A更低的位置，因此係與上述 第二實施方式同樣地可利用空氣釋出孔30A與導水口 8c 的壓力差，順暢地將水導入，進而提升淨水濾芯50的性 能。 -17- 201032884 又’根據本實施方式，因爲導水口 8 c的口徑係小於 淨化劑1 5的粒徑，因此過濾構件4 3係只要配設在空氣釋 出孔3 0 A即可，具有可削減一部分的零件數目的優點。 [第四實施方式] 其次，佐以第8圖和第9圖來說明本發明的第四實施 方式。 本實施方式的淨水濾芯60係可替代上述第一至第三 實施方式的淨水濾芯6、4 0、5 0，安裝到淨水器1來使用 〇 本實施方式的淨水濾芯60，係用來防止當被導入到 淨水濾芯60的原水的流量很多的時候所產生的溝道作用 (channeling)，因而在殼體7A內的內部結構係與上述 第一實施方式的淨水濾芯6有所不同。 具體而言，本實施方式的結構係在殻體7A的底壁部 13朝該殼體7A的頂面豎立分隔壁55，將分隔壁55的內 側當作淨化室S 1 a。 分隔壁55係以圍繞在形成於底壁部13上的孔13a的 方式沿著周方向設置，因而區分成淨化室Sla以及形成在 分隔壁55的外側的整流室S3的兩種空間。而且本實施方 式係將導水口 8a的位置設在：由底壁部13的平面圖觀察 時係避開淨化室S 1 a上的略圓形狀的開口區域Aw的位置 上。 根據這種結構’係可防止產生所謂的溝道作用（亦即 -18- 201032884 從導水口 8a所導入的原水朝向排水口 7c係沿著最短距離 且最容易流動的流路行進的現象），藉此，可防止原水尙 未經淨化就從排水口 7c排出去的情事之發生。 在分隔壁5 5的上部係形成有較之淨化劑1 5的粒徑更 寬的細縫5 5 a，溢流到整流室S 3內的淨化劑1 5係可利用 來自導水口 8a的水流將其流送到淨化室S 1 a內。 本實施方式中，用以防止淨化劑15的洩漏之多孔質 φ 板片18A係設在分隔壁55內側的淨化室Sla的下方，用 來將多孔質板片18A往上抬的凸部19A也是形成在分隔 壁55的內側。此外，細縫55a的下端部55b的位置係位 於：只要依靠從該下端部55a充塡到多孔質板片18A的深 度爲止的淨化劑1 5的量即可將原水充分地淨化之位置爲 宜。 如上所述，本實施方式的淨水濾芯60係在殻體7A 的底壁部13朝該殼體7A的頂面豎立分隔壁55以設置用 © 來收容淨化劑15的淨化室Sla，並且將導水口 8a設在： 由底壁部13的平面圖觀察時係避開前述淨化室Sla上的 開口區域Aw的位置的蓋子8上。因此，可防止溝道作用 的發生而可確實地將原水加以淨化，因此可提升淨水濾芯 6〇的性能。 又，藉由利用導水口 8a與設在較之該導水口 8a更高 位置處的空氣釋出孔30，係與上述第一實施方式同樣地 能夠順暢地將水導入。 接下來，將佐以第9圖來說明第四實施方式的淨水濾 -19- 201032884 芯60的變形例。 本實施方式的淨水濾芯60A係可替代上述第一至第 四實施方式的淨水濾芯6、40、50、60，安裝到淨水器1 來使用。分隔壁55A係與上述第四實施方式的淨水濾芯 60的分隔壁55的結構不同。 具體而言’本變形例的結構，係將分隔壁55A設置 成延伸到達蓋子8的基底部21，並且將形成於分隔壁 55A的上部的細縫55c的寬度設定成小於淨化劑15的粒 徑。 根據這種結構，本變形例係可防止原本被收容在淨化 室S 1 a內的淨化劑1 5溢流到整流室S2，因此就無需在導 水口 8a設置過濾構件，具有可削減零件數目的優點。 [第五實施方式] 其次，佐以第10圖和第11圖來說明本發明的第五實 施方式。 本實施方式的淨水濾芯70係可替代上述第一至第四 實施方式以及第四實施方式的淨水濾芯6、40、50、60、 60A，安裝到淨水器1來使用。導水口 7a以及空氣釋出孔 30B的位置係與上述第四實施方式的淨水濾芯60的有所 不同。 具體而言，本實施方式的結構係在蓋子8C的基底部 21形成空氣釋出孔3 0B，並且在殼體7C的周壁部14開 設導水口 7a。 -20- 201032884 如第10圖所示，空氣釋出孔30B係設在基底部21的 略中心部。在空氣釋出孔3 0B利用例如：內插成型等方式 成一體地張設有透水性的過濾構件43，該過濾構件43的 孔徑係小於淨化劑1 5的粒徑，以防止淨化劑1 5的洩漏。 爲了讓導水口 7a與空氣釋出孔30B的高低差儘可能 地擴大，本實施方式中係將導水口 7a設在：被形成於周 壁部14的外表面的凸條27的附近而且較此凸條27更上 φ 部的地方。 在底壁部13係與上述第四實施方式同樣地，朝殼體 7 C的頂面豎立分隔壁5 5，在分隔壁5 5的內側形成淨化室 Sla。而且本實施方式中，除了將分隔壁55設置成延伸到 達較之導水口 7a更高的位置之外，形成於分隔壁55的細 縫55a的下端部55b也是位於較之導水口 7a更高的位置 〇 具有上述的結構之本實施方式的淨水濾芯70，原水 〇 室4的原水係沿著分隔壁體3的凹部3b而從形成在殼體 7的周壁部14上的導水口 7a被導入。藉由將導水口 7a 設在殼體7的周壁部14上，可擴大導水口 7a與空氣釋出 孔30B之間的高低差，因此可讓水的導入更爲順暢。 又，本實施方式係將分隔壁55以及細縫55a的下端 部55b設在較之導水口 7a更高的位置，因此係與上述第 四實施方式同樣地，可防止所謂的溝道作用（亦即，從導 水口 7 a所導入的原水朝向排水口 7 c只流經過比較容易流 動的流路的現象）的發生。藉此，可防止原水尙未充分的 -21 -
