201144230 六、發明說明： 【發明所屬技術領域】 本發明是關於淨水器。 【先前技術】 在一般家庭中，爲了將自來水等的原水淨化成飲用水 來利用，乃活用例如：冷水壺型的淨水器。這種冷水壺型 的淨水器係具備：具有位於上側的原水室與位於下側的淨 水室之本體容器；以及介裝在原水室與淨水室之間的淨水 濾芯而構成的。並且藉由讓原水通過淨水濾芯而生成淨水 ，其所生成的淨水則是存放在淨水室內。 然而，這種冷水壺型的淨水器，通常都是形成可讓本 體容器放在電冰箱內保管的大小，所以每一次可以生成的 淨水的量受到限制。因此，雖然可藉由反覆的使用來獲取 較多的淨水量，但是，特別是在夏天的時候，作爲飲用水 之這種淨水的使用量會增加，因此必須具有可在短時間內 就將原水予以淨化的能力。 因此，在於例如：專利文獻1所揭示的技術，係在淨 水濾芯之過濾盃與蓋子之間，配置一個呈圓頂狀的內置布 ’並且設成將該內置布與活性碳之類的淨化劑保持接觸， 以將從篩網狀入口所導入進來的水之表面張力予以阻絕， 藉此來抑制因爲空氣的背壓所產生的通水阻力。 [先行技術文獻] [專利文獻] -5- 201144230 [專利文獻1 ]日本特開平1 0 - 7 6 2 5 3號公報 【發明內容】 [發明所欲解決的問題] 然而，上述習知技術在使用的初期雖然可以減低通水 阻力，但是因爲水流都集中到內置布的接觸部，所以原本 係呈接觸狀態的淨化劑逐漸被推擠流走而變成不再接觸了 ，因此在使用的後期，會有因爲通水阻力增大而變得無法 順暢地生成淨水的可能性。 因此，本發明之目的係在於獲得：無論是在使用初期 或使用後期都可穩定且順暢地生成淨水的淨水器。 [用以解決問題之手段] 本發明的淨水器，係具備： 本體容器，係形成有供儲存原水的原水室以及供儲存 淨水的淨水室； 濾芯收容部，係被設在用來劃分前述原水室以及淨水 室的分隔壁的底壁部，且形成有連通前述原水室與前述淨 水室的開口部； 淨水濾芯，係在內部形成有用來充塡淨化劑的淨化室 ，並配置有覆蓋前述淨化室的過濾膜，而且在較之前述過 濾膜更高位置處設有導水口； 在於將前述本體容器的底壁部處於下方的狀態下，可 生成淨水之淨水器，其特徵爲： -6- 201144230 在將前述淨水濾芯裝設到前述濾芯收容部的使用狀態 下，係將前述過濾膜相對於前述本體容器的錯垂軸線呈傾 斜配置。 [發明之效果] 根據本發明，在將淨水濾芯裝設到濾芯收容部的使用 狀態下，係將淨水濾芯的過濾膜相對於本體容器的鉛垂軸 線呈傾斜配置。因此’可使得淨化劑接觸於呈傾斜狀態的 過濾膜之較低的一側’因而可確保流路’並且可利用已經 通水後的水很容易使得集中在過濾膜之較高的一側的空氣 往外部排出，所以無論是在使用初期或是在使用後期皆可 穩定順暢地生成淨水。 【實施方式】 以下，將佐以圖面來詳細說明本發明的實施方式。又 ，在於以下的數個實施方式中係包含同樣的構成要素。因 此，在以下的說明當中，針對於這些同樣的構成要素都賦 予共通的元件符號，並且省略其重複的說明。 〔第1實施方式〕 第1圖以及第2圖係顯示本發明的淨水器的第1實施 方式之圖。 如第1圖所示，本實施方式的淨水器1係製作成：冷 水亞型淨水益’係具備·略呈有底筒狀的本體谷器2、被 201144230 形成相同的略呈有底筒狀的內部容器（亦即，分隔壁）3、以 及淨水濾芯10。並且藉由在本體容器2的筒內，以仰望著 該本體容器2的頂壁部8的方式配置著內部容器3，而將 內部容器3的內側劃分爲原水室4，將外側劃分爲淨水室 5 〇 在內部容器3的底壁部3a係形成略呈圓筒狀的凹部（ 濾芯收容部）3b，其具有連通原水室4與淨水室5的開口 部3 c，將略呈圓筒狀的淨水濾芯1 0從上方插入這個凹部 3b直到底部爲止，而嵌裝著該淨水濾芯1 0。又，在這種 狀態下，淨水濾芯1 〇的下部1 〇b係從開口部3 c露出來而 面臨著淨水室5。然後，在於將本體容器2的底壁部2 a位 於下方的狀態下，將原水注入到原水室4，並且藉由讓原 水通過淨水濾芯1 〇而生成淨水，所生成的淨水則是儲存 在淨水室5。 在原水室4的上方係配置著：被形成有給水口 8a的 頂壁部8。給水口 8a係利用一個藉由鉸鍊9a而可轉動地 安裝在頂壁部8的上開式蓋子9，而被該蓋子9可開閉地 蓋住。原水係在於將蓋子9往上方打開的狀態下，經由給 水口 8 a供給到原水室4內。 又，在內部容器3的側壁部3e與本體容器2之間’ 係形成有一個從淨水室5往上方延伸的通路7 ’在於本體 容器2或頂壁部8之相當於通路7的上端部的位置處’係 形成有一注水口 7a。在本β施方式中，係藉由將本體容器 2以使得注水口 7a位在下方的方式加以傾倒（在第1圖中 -8 - 201144230 ，係將本體容器2朝順時鐘方向傾倒），而將原本儲存在 淨水室5內的淨水，經由通路7而從注水口 7a排出去。 又，在本實施方式中，注水口 7 a係利用一個可轉動地被 支承於本體容器2或頂壁部8上的上開式的蓋體20，而被 該蓋體20可開閉地蓋住。這種情況，係可製作成··將本 體容器2傾倒時，可利用蓋體20本身的重量或水的動壓 等來使得蓋體20轉動而將注水口 7a打開。 淨水濾芯1 〇係如第2圖所示，係具備：頂面呈開口 ，並且形成有可充塡入淨化劑1 2的淨化室S2之有底筒狀 的殼體14;覆蓋著前述淨化室S2的過濾膜16;被結合成 可覆蓋住殼體14的開口部14e，並且在較之前述過濾膜 16更高位置處形成有導水口 11之蓋子15。 蓋子15係具備：從外筒17a的頂壁17b大致沿著淨 水濾芯10的中心軸線Αχ讓內筒17d往下方延伸之盃體 1 7 ;藉由令突出部1 8a插穿過內筒1 7d的下端部而在內側 形成添加劑收容室S 1之盃蓋1 8。在這個添加劑收容室S 1 內，係收容著例如：直徑數厘米程度的粒狀鈣之類的添加 劑（未圖示）。 在盃體17的外周壁17c上，係沿著外周方向間斷地 形成有略呈矩形狀的導水口 1 1。在這個導水口 Π係利用 內置成形方法而形成有篩網1 1 a，用來抑制添加劑從導水 口 11溢出。又，在盃蓋18的外周壁18b上，係形成有由 其下端往上方延伸的細縫狀的缺口 18c。缺口 18c的寬度 被設定成小於添加劑的粒徑，藉此，可抑制添加劑從缺口 -9 - 201144230 1 8 c溢出。 根據以這種方式來構成的本實施方式的蓋子15’從原 水室4經由導水口 1 1而導入的水，係通過盃蓋1 8的缺口 1 8c而流入添加劑收容室S 1內，與添加劑接觸過後的水則 是再度通過缺口 1 8c而流出到殻體1 4內。 殼體1 4是利用一個被配置在沿著淨水濾芯1 0的中心 軸線Αχ的位置上的略呈圓筒狀的筒體19，而在直徑方向 上被分隔開來，在本實施方式中，係將筒體1 9的外周側 當作用來收容淨化劑（例如：粒狀或粉狀的活性碳等）1 2之 淨化室S2 ;將筒體1 9的筒內當作用來收容濾過材（例如： 被彎曲成倒逆U字狀的中空紗膜等）13之過濾室S3。 根據這種結構，通過了過濾膜1 6而被導入的水係依 序地經由淨化室S2以及過濾室S3，再從下端部1 〇b的排 水口 1 〇c排出去。筒體1 9係被嵌入於形成在殼體1 4的底 壁14a的中央部之往下方凹陷的凹部14b，藉此，筒體19 係被沿著淨水濾芯1 〇的中心軸線Αχ朝上下方向豎立地設 置。 淨化室S2係受到：殼體1 4的外周壁1 4c、筒體1 9、 底壁1 4a、以及過濾膜1 6所圍繞著，因而形成具有略呈圓 環狀的剖面的筒狀。在本實施方式中，過濾膜1 6係形成 環狀而且圍繞著筒體1 9，將其外緣部1 6a夾置於殻體1 4 與蓋子1 5之間而加以固定。至於這種過濾膜1 6，係可適 合採用：不織布、海綿之類的發泡體膜片，必要時既可以 產生撓曲變形，平時則是可藉由其本身的重量而保有不會 -10 - 201144230 從平板形狀發生變形的這種程度之自我保形性（彈性）。又 ，在本實施方式中，係在筒體19的上端裝設有一盃蓋18 ，藉由從這個盃蓋1 8之朝徑向外側突出的凸緣部1 8 d，可 使得過濾膜1 6的內緣部1 6b不會反翹到凸緣部1 8 d的更 上方。藉由這種結構，即使在於將淨水濾芯10從淨水器1 取出的狀態下，將淨水器1予以傾倒或者上下顛倒時，也 因爲過濾膜16被凸緣部18d所卡止而且間隙被塞住，因 此可抑制淨化劑1 2從淨化室S2漏出到添加劑收容室S 1 、蓋子1 5的這一側。 在筒體19的下部係形成有一連通口 19a，藉由這個連 通口 19a，淨化室S2與過濾室S3係互相連通在一起。在 淨化室S2內受到淨化劑1 2的吸附而除去雜質之後的水係 經由連通口 1 9a而被導入到過濾室S3內。 在過濾室S3內，收容著作爲濾過材13用的細吸管狀 的中空紗膜，係將許多中空紗膜束在一起，且以彎曲成略 呈倒U字狀的狀態收容於過濾室S3內。從過濾室S3內流 出之已經通過中空紗膜的膜壁而穿透到膜內的水，係先通 過膜內之後，再流出到過濾室S3的下端部，而從排水口 1 〇c流出到淨水室5。水在通過中空紗膜的膜壁的時候， 原本含在水中的雜質就被過濾掉。作爲過濾材1 3用的中 空紗膜，係在較之連通口 1 9 a更下方處，利用黏著劑（未 圖示）一方面將其間隙予以塡滿，一方面又因此而被固定 於筒體1 9內，利用這個黏著劑可阻止水未通過中空紗膜 就直接從過濾室S 3內部流出去的情況。 -11 - 201144230 然而，在淨水濾芯1 〇內的各部位，尤其是在過濾膜 1 6與淨化劑1 2之間，如果不小心有空氣累積的話’因爲 水的重力與空氣的浮力互相抗衡，因而導致水的流路被空 氣所堵塞住。如此一來，就無法獲得所期望的流量，而會 產生若想要獲得淨水需要耗費很多時間之虞慮。因此，在 這種結構的淨水濾芯1 〇中，如果在進行通水時，可以一 面將存在於內部的空氣予以順暢地排出，一面將水予以導 入的話，則可以較短的時間來將原水予以淨化。因此，在 本實施方式中，在於將淨水濾芯10裝設在作爲濾芯收容 部用的凹部3b的使用狀態下，係將過濾膜1 6相對於本體 容器2的鉛垂軸線A w (重力方向）呈傾斜配置。 具體而言，如第1圖以及第2圖所示，在本實施方式 中，係將凹部3b的外周壁部3d形成：相對於本體容器2 的鉛垂軸線Aw係呈傾斜，藉由將淨水濾芯1 0裝設在這 個凹部3 b，即可令整個淨水瀘芯1 0呈傾斜。亦即，淨水 濾芯的中心軸線Αχ相對於本體容器的鉛垂軸線Aw係呈 現X度的傾斜。 又，在於作爲蓋子1 5的頂壁之盃體1 7的頂壁1 7b上 ，係形成有複數個洩氣孔17e、17f。這幾個洩氣孔17e、 1 7 f係設在較之導水口 1 1更高位置，洩氣孔1 7e係位於內 筒1 7d的內側，並且洩氣孔1 7f係位於內筒1 7d的外側， 被形成IT穿頂壁17b。 因此，過濾室S3內的空氣係經由盃蓋1 8的突出部 18a、盃體17的內筒〗7d的筒內而從洩氣孔17e排出去。 -12- 201144230 又，淨化室s 2內的空氣則是經由過濾膜1 6、盃蓋17的 缺口 18c而進入添加劑收容室S1內，在盃體17的外周壁 1 7 c與內筒1 7 d之間上昇之後而從洩氣孔1 7 f排出去。 此時，在本實施方式中，因爲是將整個淨水濾芯 設置成相對於本體容器2的鉛垂軸線Aw呈傾斜，所以可 使存在於過濾膜1 6與淨化劑1 2之間的空氣S進行置換。 並且讓淨化劑1 2接觸於傾斜後的過濾膜1 6之較低的一側 ，藉以確保流路而能夠使得水很容易滲透到淨化室S2。 此外，又可以藉由已經通水後的水，很有效率地來將匯集 在過濾膜1 6之較高的一側的空氣S往外部擠壓出去，從 洩氣孔1 7b排出到外部。是以，根據本實施方式的淨水器 1，在進行通水時，係可一面將存在於內部的空氣順暢地 排出，一面將水導入，所以無論是在使用初期或使用後期 都可穩定順暢地生成淨水。 如以上所詳述的這樣，根據本實施方式，在於將淨水 濾芯1 0裝設在作爲濾芯收容部用的凹部3b內的使用狀態 下，係將淨水濾芯1 〇的過濾膜1 6配置成：相對於本體容 器2的鉛垂軸線Aw呈傾斜。因此，可藉由讓淨化劑12 與傾斜後的過濾膜1 6之較低的一側相接觸，因而確保住 流路，並且利用已經通水後的水而可很容易將匯集在過濾 膜1 6之較高的一側的空氣S往外部排出。其結果，無論 是在使用初期或使用後期均可穩定且順暢地生成淨水。 特別是在本實施方式中，係藉由將凹部3b的外周壁 部3 d設成傾斜，而使得整個淨水濾芯1 〇係相對於本體容 -13- 201144230 器2的鉛垂軸線Aw保持傾斜狀態。因此，可使得充塡在 淨化室2內的淨化劑1 2傾斜而與過濾膜1 6互相接觸。所 以即使水流集中在接觸部，亦可抑制淨化劑1 2被擠壓流 走的現象，可令淨化劑1 2穩定地與過濾膜1 6互相接觸。 再者，根據以這種方式來將整個淨水濾芯1 0相對於 本體容器2的鉛垂軸線Aw構成傾斜的結構，通水後的水 係集中在過濾膜1 6之較低的一側（接觸部），並且淨化室 S 2的空氣S則是匯集在過濾膜1 6之較高的一側。因此， 可以有效地利用水的重力與空氣的浮力之差値，將淨化室 S2內的空氣S很有效率地往外部排出。 又，在本實施方式中，係採用將凹部3b的外周壁部 3 d製作成：相對於本體容器2的鉛垂軸線Aw保持傾斜的 結構。因此，只要將設在內部容器（分隔壁）3的底壁部3 a 上的凹部3b製作成傾斜即可，使用比較簡單的方式就可 以製造》 其次，將佐以第3圖及第4圖來說明本實施方式的淨 水濾芯1 0的變形例。第3圖係顯示上述實施方式的淨水 濾芯的第1變形例之圖。 第3圖所示的第1變形例的淨水濾芯1 0 A，係在淨化 室S2設有：可將淨化劑1 2朝向過濾膜1 6彈推的彈推機 構。 具體而言，在本變形例中，彈推機構係由：其中一端 部被卡止在殻體1 4的底壁1 4a上的彈簧2 1、以及結合在 這個彈簧2 1的另一端部上的篩網狀的可動分隔板22所構 -14- 201144230 成的。並且淨化劑1 2係被充塡在可動分隔板2 2之上方。 此外，在冷水壺型的淨水器1中，是利用水的重力來 執行淨化工作，因此淨化劑（例如：活性碳）1 2的粒徑愈細 的話愈有效率，對於性能提昇較有幫助。然而，如果將太 過於細小的淨化劑充塡在可動分隔板22上的話，則會有 使得流量降低之傾向，因此，一般是採用：約1 0號網目 (mesh)至32號網目程度（亦即，0.5厘米至2厘米程度的 粒徑）之淨化劑。但是，若考慮到要防止粉碎微粒的流出 ’最好是使用較大號數的網目，因此在本變形例中所採用 的可動分隔板2 2，係利用內置成型方式或一體成型方式設 置了約100號網目程度（0.2厘米程度的口徑的孔）的篩網 。此外’即使說是淨化劑1 2從可動分隔板22流出，在本 變形例中’也是與上述實施方式同樣，在筒體1 9的內側 形成有一配置著細小吸管狀的中空紗膜來作爲過濾材1 3 之過濾室S 3 ’因此淨化劑1 2不會漏出到淨水室5。 這種結構的淨水濾芯1 0A，係利用可將淨化劑1 2朝 向過濾膜16彈推的彈簧21與可動分隔板22，而可使得淨 化劑1 2確實地與過濾膜丨6接觸。其結果，可增加淨化劑 12與過濾膜16的接觸面積而可令水更容易滲透到淨化室 S2內。 此外’在本變形例中，雖然是使用可動分隔板2 2與 彈簧2 1來當作彈推機構，但未必一定要使用這種方式， 亦可採用例如：可動分隔板與浮球組合等的方式。 第4圖係顯示上述實施方式的淨水濾芯的第2變形例 -15- 201144230 之圖。 第4圖所示的第2變形例的淨水濾芯1 〇 B，係在淨化 室S 2設置了 ：可將已經通水後的水朝向作爲孔部用的連 通孔1 9a誘導之誘導部。 具體而言’在本變形例中，作爲誘導部用的集水板23 係橫跨在殼體1 4的底壁1 4 a與外周壁1 4 c而被結合於殼 體上’利用這個集水板23可將水朝向作爲孔部用的連通 孔1 9 a誘導。 然而，在於本變形例的這種：將淨水濾芯1 Ο B配置成 相對於本體容器的鉛垂軸線A w (請參考第1圖）呈傾斜的 構成方式中，已通水後的水會有滯留在呈傾斜的較低之一 側也就是殼體14的角部1 4g之虞慮。然而，在本變形例 中，係在這個角部1 4g將集水板23設成：傾斜預定的角 度，因此可以減少滯留在殻體1 4的角部1 4 g之所謂的「 死水」。此外，在本變形例中，集水板2 3之相對於底壁 1 4 a的傾斜角度’最好是設定成大於或等於淨水濾芯1 〇 B 之相對於鉛垂軸線Aw的傾斜角度。 這種構成方式的淨水濾芯10B，係可藉由作爲誘導部 用的集水板2 3來將水朝向連通孔1 9 a誘導，因此可抑制 淨化室S 2內的滯留水而可順暢地生成淨水。 尤其是在本實施方式中，誘導部就是：橫跨在相當於 淨水濾芯1 0B的底壁與外周壁之殼體1 4的底壁丨4a與外 周壁l4c之間而設的集水板23，並且將這個集水板23之 相對於底壁】4 a的傾斜角度設定成：大於或等於淨水濾芯 -16- 201144230 1 0 B之相對於錯垂軸線A W的傾斜角度。因此，可 因爲將淨水濾芯1 0B傾斜配置而產生的滯留在殻體 角部14g之所謂的「死水」。 此外，在本變形例中，作爲誘導部用的集水板 然是以橫跨殼體14的底壁14a與外周壁14b之間 個構件來構成的，但是並不限定於這種方式，亦可 如：將殼體1 4的底壁1 4a製作成傾斜狀來構成集水 〔第2實施方式〕 其次，佐以圖面來說明本發明的第2實施方式 圖係顯示本實施方式的淨水器之圖。 本實施方式的淨水器1 A係與上述第1實施方 地，在於將淨水濾芯1 〇裝設於凹部3b的使用狀態 將過濾膜1 6配置成相對於本體容器2A的鉛垂軸線 成傾斜。 此處，本實施方式與上述第1實施方式之主要 點係在於：因爲本體容器2 A係被形成相對於該本 2 A的鉛垂軸線Aw構成傾斜，所以過濾膜]6相對 軸線Aw也是呈傾斜配置。 具體而言，係如第5圖所示般地，在本實施方 係將本體容器2 A的底壁部2 a作成傾斜，藉由將這 部2 a載置於水平面上，就可以將整個本體容器2 A 鉛垂軸線Aw構成傾斜。 因此，內部容器3 A的底壁部3 a以及作爲濾芯 以減少 14的

1 6之較高的一側的空氣S很容易就排出到外 無論是使用初期或者是使用後期都可穩定且順 水。 又，可將充塡在淨化室2內的淨化劑1 2 接觸於過濾膜1 6。因此，即使水流集中於接觸 制淨化劑1 2被擠壓流走的現象，可讓淨化劑] 觸於過濾膜1 6。 再者，已通水後的水係集中在過濾膜1 6 側（接觸部），並且淨化室S 2的空氣係集中在過 較高的一側，有效地利用水的重力與空氣的浮 可很有效率地將淨化室S

Description of the Invention: [Technical Field] The present invention relates to a water purifier. [Prior Art] In the general household, in order to purify the raw water such as tap water into drinking water, for example, a cold water bottle type water purifier is used. The water bottle type water purifier includes a main body container having a raw water chamber on the upper side and a clean water chamber on the lower side, and a water purification filter element interposed between the raw water chamber and the clean water chamber. And the purified water is generated by passing the raw water through the water purification filter, and the purified water generated is stored in the clean water room. However, such a cold water bottle type water purifier is usually formed in a size that allows the container to be stored in a refrigerator, so that the amount of purified water that can be generated each time is limited. Therefore, although it is possible to obtain more water purification by repeated use, especially in the summer, the amount of purified water used as drinking water will increase, so it must be available in a short time. The ability to purify raw water. Therefore, for example, the technique disclosed in Patent Document 1 is to arrange a dome-shaped built-in cloth between the filter cup and the lid of the water purification cartridge, and to provide purification of the built-in cloth and activated carbon. The agent is kept in contact to prevent the surface tension of the water introduced from the mesh-like inlet from being blocked, thereby suppressing the water-passing resistance due to the back pressure of the air. [PRIOR ART DOCUMENT] [Patent Document] - 5 - 201144230 [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. Although the initial stage of use can reduce the water flow resistance, since the water flow is concentrated to the contact portion of the built-in cloth, the purifying agent which is originally in contact state is gradually pushed away and becomes no longer in contact, so in the later stage of use, There is a possibility that the water can not be smoothly generated due to the increase in the water resistance. Therefore, the object of the present invention is to obtain a water purifier which can stably and smoothly generate purified water at the beginning of use or in the later stage of use. [Means for Solving the Problem] The water purifier according to the present invention includes: a main body container in which a raw water chamber for storing raw water and a clean water chamber for storing clean water are formed; and a filter cartridge accommodating portion is provided for The bottom wall portion of the partition wall of the raw water chamber and the clean water chamber is partitioned, and an opening portion that communicates between the raw water chamber and the clean water chamber is formed; and the water purification filter has a clean room for charging a purifying agent therein.

[Effect of the Invention] According to the present invention, in a state in which the water purification cartridge is installed in the cartridge accommodating portion, the filtration membrane of the water purification cartridge is disposed obliquely with respect to the vertical axis of the main body container. Therefore, 'the cleaning agent can be brought into contact with the lower side of the filter membrane in an inclined state' thus ensuring the flow path' and it is easy to concentrate on the higher side of the filter membrane by using water that has been passed through the water. The air is discharged to the outside, so that the clean water can be generated smoothly and smoothly at the beginning of use or at the end of use. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Further, in the following embodiments, the same constituent elements are included. Therefore, in the following description, the same components are denoted by the same reference numerals, and the repeated description thereof will be omitted. [First Embodiment] Fig. 1 and Fig. 2 are views showing a first embodiment of a water purifier according to the present invention. As shown in Fig. 1, the water purifier 1 of the present embodiment is manufactured such that the cold water sub-type water purification system has a bottomed tubular body 2 and a slightly bottomed bottom formed by 201144230. A cylindrical inner container (i.e., a partition wall) 3, and a water purification cartridge 10. Further, the inner container 3 is disposed in the cylinder of the main body container 2 so as to face the top wall portion 8 of the main body container 2, and the inner side of the inner container 3 is divided into the raw water chamber 4, and the outer side is divided into purified water. In the bottom wall portion 3a of the inner container 3, a recessed portion (filter cartridge accommodating portion) 3b having a substantially cylindrical shape having an opening portion 3c that communicates with the raw water chamber 4 and the clean water chamber 5, which will be slightly cylindrical, is formed in the chamber 5 The water purification cartridge 10 is inserted into the recess 3b from above to the bottom, and the water purification cartridge 10 is fitted. Further, in this state, the lower portion 1 〇b of the water purification cartridge 1 露出 is exposed from the opening portion 3 c and faces the clean water chamber 5 . Then, in a state where the bottom wall portion 2a of the main body container 2 is positioned below, raw water is injected into the raw water chamber 4, and the raw water is passed through the water purification cartridge 1 to generate purified water, and the generated purified water is Stored in the clean water room 5. Above the raw water chamber 4, a top wall portion 8 formed with a water supply port 8a is disposed. The water supply port 8a is opened and closed by the cover 9 by a top open cover 9 rotatably attached to the top wall portion 8 by a hinge 9a. The raw water system is supplied to the raw water chamber 4 via the water supply port 8a in a state where the lid 9 is opened upward. Further, a passage 7' extending upward from the water purification chamber 5 is formed between the side wall portion 3e of the inner container 3 and the main body container 2, and the upper end portion of the main body container 2 or the top wall portion 8 corresponding to the passage 7 is formed. At the position of the ', a water injection port 7a is formed. In the present embodiment, the body container 2 is tilted so that the water injection port 7a is positioned below (in the first drawing, -8 - 201144230, the body container 2 is tilted in the clockwise direction), and The purified water originally stored in the clean water chamber 5 is discharged from the water injection port 7a via the passage 7. Further, in the present embodiment, the water injection port 7a is opened and closed by the cover body 20 by a cover member 20 that is rotatably supported by the main body container 2 or the top wall portion 8. . In this case, when the body container 2 is tilted, the lid body 20 can be rotated by the weight of the lid body 20 or the dynamic pressure of water or the like to open the water injection port 7a. As shown in Fig. 2, the water purification cartridge 1 has a bottomed cylindrical casing 14 having an open top surface and a clean room S2 capable of being filled with the cleaning agent 12; The filter film 16 of the chamber S2 is combined to cover the opening portion 14e of the casing 14, and a cover 15 having a water conduit 11 is formed at a position higher than the foregoing filter film 16. The cover 15 is provided with a cup body 7 extending from the top wall 17b of the outer cylinder 17a substantially along the central axis of the water purification cartridge 10 so that the inner cylinder 17d extends downward; by inserting the projection 18 8 through the inner cylinder 1 The lid portion 18 of the additive containing chamber S 1 is formed on the inner side of the lower end portion of the 7d. In the additive storage chamber S1, for example, an additive (not shown) such as granular calcium having a diameter of several centimeters is accommodated. On the outer peripheral wall 17c of the cup body 17, a water guide opening 1 1 having a substantially rectangular shape is intermittently formed along the outer circumferential direction. In this water conduit, a screen 11a is formed by a built-in forming method for suppressing the overflow of the additive from the water conduit 11. Further, on the outer peripheral wall 18b of the cup lid 18, a slit-shaped notch 18c extending upward from the lower end thereof is formed. The width of the notch 18c is set to be smaller than the particle diameter of the additive, whereby the overflow of the additive from the notch -9 - 201144230 1 8 c can be suppressed. The water introduced from the raw water chamber 4 through the water conduit 1 by the lid 15' of the present embodiment configured in this manner flows into the additive containing chamber S1 through the notch 18c of the lid 18, and the additive. The contacted water flows out through the notch 18c into the casing 14. The housing 14 is separated in the diametrical direction by a cylindrical body 19 disposed at a position along the central axis of the water purification cartridge 10, in the present embodiment. In the middle, the outer peripheral side of the cylinder 19 is used as a clean room S2 for containing a purifying agent (for example, granular or powdery activated carbon, etc.); and the inside of the cylinder 19 is used for containing the filter. A filter chamber S3 of a material (for example, a hollow fiber membrane that is bent into a reverse U shape) 13 . According to this configuration, the water introduced through the filtration membrane 16 is sequentially discharged through the clean room S2 and the filter chamber S3 from the drain port 1 〇c of the lower end portion 1b. The cylindrical body 9 is fitted in a recessed portion 14b which is formed to be recessed downward at a central portion of the bottom wall 14a of the casing 14, whereby the tubular body 19 is slid up and down along the central axis of the water purification cartridge 1 The direction is set upright. The clean room S2 is surrounded by the outer peripheral wall 14c of the casing 14b, the cylindrical body 19, the bottom wall 14a, and the filter membrane 16 so as to form a cylindrical shape having a substantially circular cross section. In the present embodiment, the filter membrane 16 is formed in a ring shape and is fixed around the cylindrical body 19 by sandwiching the outer edge portion 16a between the casing 14 and the lid 15. As for the filter film 16, it is suitable to use a foam film such as a non-woven fabric or a sponge, and if necessary, it can cause flexural deformation, and in normal times, it can be retained by its own weight. - 201144230 Self-conformity (elasticity) of this degree of deformation from the shape of the flat plate. Further, in the present embodiment, a cup cover 18 is attached to the upper end of the cylindrical body 19, and the filter film 16 can be made by the flange portion 18 d protruding radially outward from the cup cover 18. The inner edge portion 16b does not back up to the upper side of the flange portion 18d. With this configuration, even if the water purifier 1 is tilted or turned upside down in a state where the water purification cartridge 10 is taken out from the water purifier 1, the filter film 16 is locked by the flange portion 18d and the gap It is blocked, so that it is possible to suppress the purifying agent 12 from leaking from the clean room S2 to the side of the additive containing chamber S 1 and the lid 15 . A communication port 19a is formed in the lower portion of the cylinder 19, and the cleaning chamber S2 and the filter chamber S3 are connected to each other by the communication port 19a. The water which has been adsorbed by the cleaning agent 12 in the clean room S2 to remove impurities is introduced into the filter chamber S3 via the communication port 19a. In the filter chamber S3, a hollow tubular film of a thin suction tube for the filter material 13 is housed, and a plurality of hollow fiber membranes are bundled together and housed in the filter chamber S3 in a state of being bent in a slightly inverted U shape. . The water that has flowed out of the filter chamber S3 and has penetrated into the membrane through the membrane wall of the hollow fiber membrane first passes through the membrane and then flows out to the lower end portion of the filtration chamber S3, and flows out from the drain port 1 〇c to Clean water room 5. When water passes through the membrane wall of the hollow fiber membrane, impurities originally contained in the water are filtered out. The hollow fiber membrane used as the filter material 13 is located below the communication port 19a, and the gap is filled on the one hand by an adhesive (not shown), and on the other hand, it is fixed to the cylinder. In the body 19, the adhesive can prevent the water from flowing directly from the inside of the filter chamber S3 without passing through the hollow fiber membrane. -11 - 201144230 However, in the parts of the water purification filter 1 ,, especially between the filter membrane 16 and the purifier 12, if there is accidental air accumulation, 'because the gravity of the water and the buoyancy of the air compete with each other. Therefore, the flow path of the water is blocked by the air. As a result, the desired flow rate cannot be obtained, and there is a concern that it takes a lot of time to obtain purified water. Therefore, in the water purification cartridge 1 of the above configuration, when the water is supplied, the air existing inside can be smoothly discharged, and when the water is introduced, the raw water can be supplied in a short time. Purify. Therefore, in the present embodiment, the water purification cartridge 10 is attached to the vertical axis A w of the filter container 16 with respect to the main body container 2 in the use state of the recessed portion 3b serving as the cartridge accommodating portion (gravity direction) ) is tilted. Specifically, as shown in FIG. 1 and FIG. 2, in the present embodiment, the outer peripheral wall portion 3d of the recessed portion 3b is formed to be inclined with respect to the vertical axis Aw of the main body container 2, and The water filter 10 is installed in this recess 3b, so that the entire clean water core 10 is inclined. That is, the central axis Αχ of the water purification cartridge is inclined at an angle of X with respect to the vertical axis Aw of the body container. Further, a plurality of air vent holes 17e and 17f are formed in the top wall 17b of the cup body 17 as the top wall of the cover 15 . The air vents 17e, 1 7 f are located higher than the water conduit 1 1 , the vent holes 17 7 are located inside the inner cylinder 17 d, and the vent holes 17 7 are located outside the inner cylinder 17 d. The IT is formed through the top wall 17b. Therefore, the air in the filter chamber S3 is discharged from the bleed hole 17e via the projecting portion 18a of the cup lid 18 and the inside of the inner tube 7d of the cup body 17. -12- 201144230 Further, the air in the clean room s 2 enters the additive storage chamber S1 through the notch 18c of the filter film 16 and the lid 17, and the outer peripheral wall 17c and the inner cylinder 17 of the cup body 17 After rising between d, it is discharged from the vent hole 1 7 f. At this time, in the present embodiment, since the entire water purification cartridge is disposed to be inclined with respect to the vertical axis Aw of the main body container 2, the air S existing between the filtration membrane 16 and the cleaning agent 1 2 can be made. Perform the replacement. Further, the scavenger 12 is brought into contact with the lower side of the inclined filter membrane 16 to secure the flow path so that water can easily permeate into the clean room S2. Further, it is possible to efficiently squeeze the air S collected on the higher side of the filtration membrane 16 to the outside by the water which has passed through the water, and discharge it from the vent hole 17b to the outside. Therefore, the water purifier 1 according to the present embodiment can smoothly and smoothly discharge the air existing inside while the water is being supplied, so that the water can be smoothly and smoothly in the initial stage of use or in the later stage of use. Generate clean water. As described in detail above, according to the present embodiment, in the use state in which the water purification cartridge 10 is installed in the recessed portion 3b for the cartridge accommodating portion, the filter membrane 16 of the water purification cartridge 1 is disposed. It is inclined with respect to the vertical axis Aw of the body container 2. Therefore, the cleaning agent 12 can be brought into contact with the lower side of the inclined filter membrane 16 to ensure the flow path, and the water can be easily collected in the filtration membrane 1 by using the water after the water has been passed. The air S on the higher side of 6 is discharged to the outside. As a result, clean water can be stably and smoothly generated both in the initial stage of use and in the later stage of use. In particular, in the present embodiment, by setting the outer peripheral wall portion 3d of the recessed portion 3b to be inclined, the entire water-purifying filter element 1 is tilted with respect to the vertical axis Aw of the body-capacity -13. status. Therefore, the scavenger 12 filled in the clean room 2 can be inclined to come into contact with the filter membrane 16 . Therefore, even if the water flow is concentrated on the contact portion, the phenomenon in which the purifying agent 12 is squeezed and flown can be suppressed, and the purifying agent 12 can be stably brought into contact with the filter film 16 . Further, according to the configuration in which the entire water purification cartridge 10 is inclined with respect to the vertical axis Aw of the main body container 2 in this manner, the water after the water passage is concentrated on the lower side of the filtration membrane 16 ( The contact portion), and the air S of the clean room S 2 is collected on the higher side of the filter film 16. Therefore, the difference between the gravity of the water and the buoyancy of the air can be effectively utilized, and the air S in the clean room S2 can be efficiently discharged to the outside. Further, in the present embodiment, the outer peripheral wall portion 3d of the recessed portion 3b is formed to be inclined with respect to the vertical axis Aw of the main body container 2. Therefore, the concave portion 3b provided on the bottom wall portion 3a of the inner container (partition wall) 3 can be made inclined, and can be manufactured in a relatively simple manner. Next, the third and fourth figures will be attached. A modification of the water purification cartridge 10 of the present embodiment will be described. Fig. 3 is a view showing a first modification of the water purification cartridge of the above embodiment. The water purification cartridge 10A of the first modification shown in Fig. 3 is provided in the purification chamber S2 with a bomb pushing mechanism that can push the cleaning agent 12 toward the filtration membrane 16. Specifically, in the present modification, the spring pushing mechanism is composed of a spring 2 1 in which one end portion is locked to the bottom wall 14a of the casing 14 and bonded to the other end of the spring 2 1 The mesh-like movable partition plate 22 is constructed as -14,442,430. And the purifying agent 12 is charged above the movable partitioning plate 2 2 . In addition, in the water purifier type water purifier 1, the purifying work is performed by the gravity of the water, so that the finer the particle size of the scavenger (for example, activated carbon) 12 is, the more efficient it is, and the more effective the performance improvement is. . However, if the too small purifying agent is charged on the movable partitioning plate 22, there is a tendency to lower the flow rate, and therefore, it is generally adopted: about 10 mesh to mesh number 32 ( That is, a purifying agent having a particle size of about 0.5 cm to 2 cm. However, in consideration of the prevention of the outflow of the pulverized particles, it is preferable to use a larger number of meshes. Therefore, the movable partitioning plate 22 used in the present modification is provided by a built-in molding method or an integral molding method. A screen of about 100 mesh (a hole of a diameter of about 0.2 cm). Further, even if the purifying agent 12 flows out of the movable partitioning plate 22, in the present modification, as in the above-described embodiment, a hollow fiber membrane in which a small suction tube is disposed is formed inside the cylindrical body 19 as a hollow yarn film. The filter chamber S 3 ' of the filter material 1 3 does not leak out of the clean water chamber 5 . The water purification cartridge 10A of such a structure is such that the cleaning agent 12 can be surely brought into contact with the filter membrane 6 by the spring 21 and the movable partitioning plate 22 which can push the cleaning agent 12 toward the filtration membrane 16. As a result, the contact area of the scavenger 12 with the filtration membrane 16 can be increased to allow water to more easily penetrate into the clean room S2. Further, in the present modification, although the movable partitioning plate 2 2 and the spring 2 1 are used as the pushing mechanism, it is not always necessary to use this method, and for example, the movable partitioning plate and the floating ball may be combined. The way to wait. Fig. 4 is a view showing a second modification -15 to 201144230 of the water purification cartridge of the above embodiment. The water purification cartridge 1 〇 B of the second modification shown in Fig. 4 is provided in the purification chamber S 2 : an inducing portion that can induce the water that has passed through the water to the communication hole 19 9a serving as a hole portion. Specifically, in the present modification, the water collecting plate 23 as the inducing portion is coupled to the casing across the bottom wall 14a and the outer peripheral wall 14c of the casing 14' The water plate 23 can induce water toward the communication hole 19 a for the hole portion. However, in the modification of the present invention, the water purification cartridge 1 Ο B is disposed so as to be inclined with respect to the vertical axis A w of the main body container (refer to FIG. 1 ), and the water after the water has passed through There is a concern that it stays on the lower side which is inclined, that is, the corner portion of the casing 14 of 14 g. However, in the present modification, the water collecting plate 23 is set to be inclined at a predetermined angle at this corner portion 14g, so that the so-called "dead water" remaining in the corner portion 14 g of the casing 14 can be reduced. Further, in the present modification, the inclination angle ' of the water collecting plate 2 3 with respect to the bottom wall 14a is preferably set to be greater than or equal to the inclination angle of the water purification cartridge 1 〇 B with respect to the vertical axis Aw. In the water purification cartridge 10B of the above-described configuration, the water can be induced toward the communication hole 19a by the water collecting plate 23 for the induction portion, so that the retained water in the clean room S2 can be suppressed and smoothly Generate clean water. In particular, in the present embodiment, the inducing portion is a water collecting plate provided between the bottom wall 丨4a and the outer peripheral wall 14c of the casing 14 corresponding to the bottom wall and the outer peripheral wall of the water purification cartridge 10B. 23, and the inclination angle of the water collecting plate 23 with respect to the bottom wall of 4 a is set to be greater than or equal to the inclination angle of the water purification filter element 16-201144230 1 0 B with respect to the misalignment axis AW. Therefore, the so-called "dead water" which is retained in the corner portion 14g of the casing due to the inclined arrangement of the water purification cartridge 10B can be used. Further, in the present modification, the water collecting plate for the inducing portion is configured to span the member between the bottom wall 14a and the outer peripheral wall 14b of the casing 14, but the present invention is not limited thereto. The bottom wall 14a of the casing 14 is formed in a slanted shape to form a water collection. [Second Embodiment] Next, the second embodiment of the present invention will be described with reference to the drawings. The picture of the water. In the water purifier 1A of the present embodiment and the first embodiment, the filter membrane 16 is disposed in a state of use in which the water purification cartridge 1 is mounted in the recess 3b so as to be perpendicular to the vertical axis of the main body container 2A. tilt. Here, the main point of the present embodiment and the above-described first embodiment is that since the main body container 2A is formed to be inclined with respect to the vertical axis Aw of the present 2 A, the filter film 6 is also opposed to the axis Aw. Tilt configuration. Specifically, as shown in Fig. 5, in the present embodiment, the bottom wall portion 2a of the main body container 2A is inclined, and by placing the portion 2a on a horizontal surface, the entire The body container 2 A has a vertical axis Aw that is inclined. Therefore, the bottom wall portion 3a of the inner container 3A and the other as a filter element to reduce the size of 14 are by way of example. . In the same manner as in the fifth embodiment, the different body containers of the Aw structure are in the vertical type, and the recessed portions 3b for the bottom wall with respect to the accommodating portion -17-201144230 are inevitably formed with respect to the vertical axis Aw to protect the water-purifying filter element 1 In this recess 3b, it is possible to form an inclination with respect to the vertical axis Aw. According to the water purifier 1 A purifying agent 1 2 of the present embodiment having the above configuration, the lower side of the inclined filter membrane 16 can ensure the flow path, and the water after the water can be used can be used for the sinking. The air S on the higher side is easily discharged to the outside, stable or smooth in both the initial stage of use and the later stage of use. Further, the cleaning agent 1 2 charged in the clean room 2 can be brought into contact with the filtration membrane 16 . Therefore, even if the water flow is concentrated on the phenomenon in which the contact cleaning agent 12 is squeezed away, the cleaning agent can be allowed to hit the filtration membrane 16. Furthermore, the water that has passed through the water is concentrated on the side of the filter membrane 16 (contact portion), and the air in the clean room S 2 is concentrated on the higher side, effectively utilizing the gravity of the water and the floating of the air. The air S in the clean room S 2 is discharged to the eve of the present invention. [Third Embodiment] Next, a third embodiment of the present invention will be described with reference to the drawings, and a water purifier according to the present embodiment will be described. In the water purifier 1B of the present embodiment and the first solid portion, the use of the water purification cartridge 10 in the recessed portion 3b is such that the filter membrane 16A is disposed to be inclined with respect to the vertical direction of the main body container 2, The water filter cartridge 1 is collected in the filter membrane portion by contacting the phases. Therefore, it is possible to smoothly generate the slanting portion, or to suppress the difference between the force of the furnace film 16 and the lower portion. the way. In the same state of the sixth embodiment, the axes Aw _ -18- 201144230 are inclined. Here, the main difference between the present embodiment and the above-described first embodiment is that the outer peripheral wall portion 3 d of the recessed portion 3 b is formed along the vertical axis A w of the main body container 2, and the water purification filter cartridge 丨The dam is attached to this recess 3 b ' and the filter film 16 A is set to be inclined with respect to the misalignment axis aw. Specifically, the present embodiment is a cylindrical flange portion 14f formed on the outer peripheral edge of the opening portion 14e of the casing 14A, as shown in Fig. 6, and a flange portion 14f to be formed on the cover 15A. The same cylindrical flange portion 17g of the lower portion of the cup body 17A is formed to be inclined with respect to the misalignment axis Aw. Further, the outer edge portion 16a of the filter membrane 16A is interposed between the pair of flange portions 14f and 17g to be fixed. According to the water purifier 1 B of the present embodiment having the above-described configuration, the flow path can be secured and utilized by bringing the cleaning agent 1 2 into contact with the lower side of the inclined filter membrane 16 A. The water that has passed through the water can easily discharge the air S collected on the higher side of the filter membrane 16 6 to the outside. Therefore, clean water can be stably and smoothly generated both in the initial stage of use and in the later stage of use. The above is a description of the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and various modifications are possible. For example, the water collecting plate 23 used as the inducing portion is not limited to the water purifiers of the first and second embodiments in which the entire water purification cartridges 10, 10A, and 10B are inclined with respect to the vertical axis Aw. 1, 1A can also be applied to the water purifier 1 B of the above-described third embodiment in which only the filter membrane 16 6 is kept inclined. In this way, the water can be induced by the water collecting plate 23 toward the communication hole 19a, so that the retained water in the clean room S2 can be suppressed and the purified water can be smoothly generated.
