200934915 九、發明說明： 發明領域 本發明係有關於一種用以攔截洗衣機等之排水中所含 5 碎屑等異物之過濾裝置。 C先前技術3 發明背景 ▲ 使用洗衣機時，洗衣水中常有來自衣服之碎屑、殘污 〇 等異物產生。此時，該等異物若就此直接自洗衣機本體排 10 出，會導致阻塞洗衣機本體之排水泵、排水閥、排水路徑 甚至是通往設置洗衣機之房屋之下水道等排水管路。因 此’以往以來多有業者提出用以攔截前述碎屑等等之過濾 裝置及包含有用過濾裝置之洗衣機（參照例如日本專利公 開公報2002-282616號）。 15 第7圖係顯示具有習知過遽裝置之洗衣機之外觀圖。第 〇 8圖係該過濾裝置周邊之立體圖，其為顯示打開蓋體時之狀 態之立體圖。第9圖係該過濾裝置之截面圖，第1〇圖係該過 遽裳置之蓋體部分之正面圖。 第7圖中，洗衣機之本體1之前面右下方配設有蓋體 —20⑼，且其内部具有後述之過遽裝置構造。第8圖中顯示打 開前述蓋體10!時之狀態。蓋體101通常由塑膠成形構件製 成，且其下端經軸支成可旋動狀態’俾其上端側可以該下 端為中心朝箭頭J方向關閉。蓋體101之背面設有突出之一 條傾斜延伸之肋條102,及前端加工成_之二二。又， 5 200934915 於蓋體101之内部，配置有在將過濾裝置自本體1取出或安 裝到本體1等之過程時操作之用之罩體35。此外，於罩體35 設置有突出且與其呈一體狀態之用以旋轉罩體35的握持部 35b。 5 第9圖之截面圖中，於筒狀過濾殼體34之前部(在第9圖 中之左側）設有具備階部34d而擴徑之擴徑部47。該擴徑部 47具有螺紋部37之構造，且罩體35隔著橡膠等彈性體構成 之水封墊片42而藉該螺紋部37螺鎖於過濾殼體34。 罩體35之後方（在第9圖中之右側）形成有凸卡合部 10 35a ’且於過滤體36形成有與之呈一體且可卡合於該凸卡合 部35a之凹卡合部36a。並且藉由該等凸卡合部35a及凹卡合 部36a兩者間之卡合，罩體35和過濾體36連结在一起。因 此’藉由旋轉罩體35使之自螺紋部37脫離，過濾體36就可 從過滤殼體34，即洗衣機之本體1取出。 15 前述過濾體％形成有筒狀且為網狀之濾網部51，俾可 使水通過但同時攔截異物。又，過濾體36配設於過濾殼體 34内部在過濾殼體34之流入口 38及流出口％之間。 於是，含有異物之洗衣排水可自流入口 38而通過濾網 部51，再以已除異物狀態從流出口 39透過排水路徑流到機 20 外之排水管路。 在如上結構之過濾裝置中，係旋轉罩體35 ，將過濾體 36自過漉殼體34取出，且除去累積於過㈣此碎肩等 物。如此之後，再將罩體35正常地螺鎖回過滤殼體34上原 本位置’遂可防止水自此部分漏出。 200934915 因此’前述習知例中乃係藉以下結構來達到防止漏水。 罩體35在蓋體ιοί之侧設有凹陷成杯狀之凹陷部351， 且於凹陷部351設有突出之通過其凹陷之略圓形面之中心 並朝直徑方向延伸之握持部35b，亦顯示於第8圖立體圖 5中。又，本體1在對應蓋體101之鉤件1〇3之部分，設有供鉤 件103插通以卡止之卡止孔1〇4。 第10圖之蓋體101之正面圖係顯示蓋體1〇1正確關閉時 之狀態。在此，中心角0顯示握持部351)自基準線1〇5起旋 轉之角度。即，當握持部35b位於中心角0呈略90度之位置 10時，朝第8圖之箭頭J方向關閉蓋體1〇1。如此一來，便如第 9圖及第10圖之虛線所示，蓋體1〇1之肋條1〇2與罩體35之握 持部35b不會抵接，蓋體1〇1可完全關閉。與此同時，鉤件 103前端之鉤狀部可卡止於卡止孔1〇4，故縱使有外力自洗 衣機外部施壓，蓋體101仍然不會輕易開啟。 15 相對於前述正常裝設狀態，當握持部35b之中心角0自 90度偏離成90度以外之狀態時，縱使關閉蓋體丨〇1，肋條1〇2 還是會與握持部35b抵接而使得蓋體1〇1無法關閉。因此， 就容易檢知因蓋體101未正常關閉而使罩體35裝設不完全 之情形。藉此，使用者可再次操作握持部35b以旋轉罩體35 20螺鎖於適當位置，輕易回復到無漏水狀態。即，使用者可 確切判斷蓋體101是否正常裝設於本體丨，防止漏水於未然。 另，前述申請案之發明之相關習知技術文獻資訊，已 知有例如曰本專利公開公報2〇〇2_282616號。 然而，前述習知技術之結構中，欲判斷罩體35是否正 7 200934915 確裝》又以可防止漏水’大前提乃係使用者必須去確認蓋體 101是否正確裝設於本體1，即蓋體101處於關閉狀態。 不過’萬-使用者注意力集中在去除來自過渡體36之 異物等清潔，而忘記關閉蓋體101之作業時，就會無法確認 5 防漏水一事。 或者’為達成設計目的亦或低成本化等而產生之減少 零件數量之要求，於是計劃在洗衣機上不設蓋體101時，前 述習知技術之結構由於其包含蓋體101之過濾裝置構造為 必要條件，所以無法實現前述不設蓋體之結構。 10 又，蓋體101 一般為塑膠成形材等製成，其配置處通常 在洗衣機下方部，因此’使用者和通過洗衣機旁之家人之 腳尖碰觸到時，或使用者未能意識到罩體35關閉狀態不良 而強行將蓋體101壓入時，將導致蓋體1〇1破損或是蓋體101 自洗衣機本體脫離’一旦發生這類事態，當然就無法確認 15 是否防漏水。 在這些問題之外，這類洗衣機之操作一般均是家庭主 婦而非專家，故還有一待解決問題係必須構造成可易懂簡 單地防止漏水。 【餐h明内容·】 20 發明揭示 本發明之過濾裝置係用以解決前述習知問題者，其不 受有無蓋體之影響’可檢知過濾裝置之罩體之裝設狀態， 且在裝設不完全時告知使用者異常狀態，以達到確實防止 洗衣機使用時之漏水。 200934915 因此，本發明之洗衣機之過濾裝置包含有罩體，於除 去異物時操作過濾裝置之開關狀態者；及電訊之傳收訊裝 置，於安裝有前述罩體之過濾殼體上在正常位置動作者， 並且，當前述罩体未正常裝設時，藉使用者處置之異常顯 5 示，通報再次關閉罩体。

含有碎屑等異物之洗衣水之排水，自流入口 12通過遽 網部10時異物將被除去，再從流出口 13藉由第1圖之排水管 6流出到機外。 在收納過濾殼體14之本體1之凹部7側，包含有一體形 成之大徑圓筒部20，圓筒部20内部收納有呈可自由旋動狀 態之罩體2。此外，圓筒部2〇之内周部具有多個突條21 ,可 將形成在罩體2之外周部23之突起22朝過濾體11側按壓。如 此—來’ 0型環18可藉由外周圓筒部17而被朝傾斜壁19按 壓’於是過濾殼體14内部之洗衣水與外部遂成水封狀態。 罩體2之外周部23之一部分收納磁性體24,並且過濾殼 體^之圓筒部2〇之外周上部一體形成有安裝板25。另，於 該圓筒部20之外周上部之安裝板25安裝有舌簧開關26。在 此’舌簧開關26係對應磁性體24之位置，配置内部之磁對 應動作部27在可近接磁性體24之位置。 第3圖之過濾装置裝設不完全時之截面圖中，如圖所示 11 200934915 之狀態’罩體2之突起22未進入過濾殼體14之圓筒部20之突 條21之内側。若是此種狀態，罩體2及過濾體11還有配置在 其兩者間之〇型環18等，相較於第2圖所示裝設好時之位 置’在第3圖中變成位在本體i外方側（即第3圖中之左側）。 5因此，藉0型環18等達成之水封效果消失殆盡，將導致漏 水。此時，由於磁性體24與舌簧開關26内部之磁對應動作 部27之間在軸向上偏移距離Η，所以磁對應動作部27不受磁 性體24影響’不動作。因此，因為舌簧開關26不動作，故 不會有來自舌簧開關26之ON訊號傳送至控制裝置3。 10 第4A〜第4D圖係顯示過濾裝置之罩體裝設狀態之動作 的平面圖，其中第4A圖顯示罩體2裝設前之準備位置。在第 4A圖中’舌簧開關26及磁對應動作部27之圓周方向位置， 由於係安裝鄰接著形成於過濾殼體14之圓筒部20上部之安 裝板25，故為罩體2之正上方向（12點鐘方向）。另一方面， 15 安裝在罩體2之磁性體24之位置在石=略90度左方向（9點 鐘方向），罩體2之旋鈕9之一字型形狀之方向設定為朝略垂 直方向。 該第4A圖之罩體2裝設前之準備位置中，形成於罩體2 之外周部23之突起22，其以一端部具有擋止部30且寬度D 20 之尺寸形狀設於下方一處，同樣地在180度相反側之上部設 有對稱形狀之第二突起22e，合計共設有2處。形成於過濾 殼體14之圓筒部20内周之突條21之位置，係自罩體2之突起 22之寬度D之左端起’朝旋轉方向離有間隙之距離C。 第4B圖係顯示藉旋鈕9將罩體2朝順時針方向旋動約45 200934915 度之召=約45度之狀態。罩體2之突起22變成進入過濾殼體 14之圓筒部20内周部之突條21之後方之前述第2圖的截面 圖狀態。然而，因為磁性體24與舌簧開關26内部之磁對應 動作部27之間有約45度角度方向之偏移，相互間距，所以 5 磁對應動作部27不會檢知磁性體24。 此外，當將罩體2旋轉略80度，自第4A圖變成第4C圖 之狀態時，首先將先行產生〇型環18之水封效果。再者，磁 性體24與舌簧開關26内部之磁對應動作部27之間雖說有卢 =約10度角度方向之偏移，不過磁對應動作部27可開始檢 10 知磁性體24。因此，舌簧開關26開始檢知ON狀態，同時罩 體2及過濾體11還有配置在其兩者間之〇型環18等，會變成 近似第2圖之截面圖之轴向形態。 如第4D圖所示，當自第4A圖狀態將旋鈕9旋轉略90度 時，磁性體24與舌簧開關26内部之磁對應動作部27之間之 15 位置關係變成谷=〇，毫無角度方向上之偏移。因此，藉磁 對應動作部27可確實檢知磁性體24，且在舌簧開關26在可 完全檢知ON狀態的同時，擋止部30抵接突條21。藉此，使 用者可判斷罩體2完全裝設好。 另，第5圖係顯示自第4B圖之箭頭A方向觀看之部分側 20 面圖。依第5圖，說明罩體2之突起22與過濾殼體14之圓筒 部20之突條21之間的軸向關係。突起22在寬度D之範圍内自 開放部22d側起，於轴向上具有薄部22a、傾斜部22b及按壓 部22c這3種高度。此外，按壓部22c與突緣部31之間形成之 間隙E設成近似僅略大於過濾殼體14之突條21之厚度尺寸 13 200934915 F。隨著罩體2之旋轉，傾斜部22b會與罩體2滑動，相對於 固定側之突條21，罩體2整體朝箭頭G方向移動，所以按壓 第2圖之過濾體11之外周圓筒部π致使達成〇型環18之水封 效果。 5 傾斜部22b之最終部之K點，設定成可變為第4C圖之冷 =略10度，俾自舌簧開關26之ON動作起就令〇型環18之水 封效果先行產生》 另，若如第4A圖所示，使旋鈕9呈略垂直從突條21與按 壓部22c在平面狀態時不相干擾之配置朝軸向插入，則按壓 ◎ 10部22c將自突條21處變成在過濾體11側。此時，旋轉旋鈕9 時’如第2圖所示，可正確按壓〇型環18且舌簧開關26亦會 動作。然而，例如當就在呈水平狀態下將過濾體丨丨插入過 濾殼體14時’突條21與按壓部22c將會相互干擾。因此，縱 然磁性體24與磁對應動作部27在平面圖上時近接，仍會造 15成第3圖之裝設不完全狀態，且有距離Η之軸向偏移，故訊 號不會傳送至控制裝置3。 如上所述，僅當磁性體24與磁對應動作部27在罩體2 〇 之旋轉方向及轴向之兩方向位置配合一致時，舌簧開關26 才變成ON狀態。藉此，罩體2正常裝設一事將自訊號線28 20 輸入控制裝置3。 接著，配合第6圖，說明當使用者欲進行洗衣運轉操作 時’若無來自舌簧開關26之訊號，即過濾裝置裝設不完全 時之洗衣機之控制流程。 首先，使用者對洗衣機之預定位置投入衣服和洗劑， 14 200934915 且使電源開關呈〇N狀態（sl〇〇)，然後設定期望運轉之行程 (S1〇1)。接著’使啟動開關呈ON狀態並進行輸入(S102)， 再於下一步驟(Si〇3)藉過濾部之舌簧開關26是否有輪入訊 號以判定其呈ON狀態或〇FF狀態。 5 此時若呈〇N狀態，洗衣機會開始運轉(S104)，進行洗 務.沖洗·脫水等一系列步驟。若舌簧開關26呈〇1^狀態， 如第6圖所示，將停止步驟進行，立即進入異常通報(S105)。 ◎ 時值此際’會於第丨圖之顯示部5顯示例如預先設定之代表 「透過使用者之操作而可修理之異常通報」的「再次關閉 10過濾部」’敦促使用者注意，且洗衣機不會運轉。然後，檢

OBJECTS OF THE INVENTION The present invention relates to a filtering device for intercepting foreign matter such as 5 debris contained in a drain of a washing machine or the like. C Prior Art 3 Background of the Invention ▲ When using a washing machine, foreign matter such as debris, dirt, and dirt from the clothes often occurs in the washing water. At this time, if the foreign matter is directly discharged from the main body of the washing machine, it may cause the drain pump, the drain valve, the drainage path of the washing machine body, or even the drain pipe leading to the water passage under the house where the washing machine is installed. Therefore, a filter device for intercepting the aforementioned debris and the like and a washing machine including the same filter device have been proposed by the prior art (see, for example, Japanese Patent Laid-Open Publication No. 2002-282616). 15 Fig. 7 is a view showing the appearance of a washing machine having a conventional device. Fig. 8 is a perspective view of the periphery of the filter device, which is a perspective view showing the state when the cover is opened. Fig. 9 is a cross-sectional view of the filter device, and Fig. 1 is a front view of the cover portion of the overhang. In Fig. 7, a cover body 20 (9) is disposed on the lower right side of the front surface of the main body 1 of the washing machine, and has a structure of a slinging device to be described later. Fig. 8 shows the state when the cover 10 is opened. The lid body 101 is usually made of a plastic molded member, and its lower end is pivotally supported by a shaft ′, and its upper end side can be closed toward the arrow J in the direction of the arrow J. The back side of the cover body 101 is provided with a rib 102 which protrudes obliquely and the front end is processed into two. Further, 5 200934915 is disposed inside the cover 101 with a cover 35 for operation when the filter device is taken out from the body 1 or mounted to the body 1 or the like. Further, the cover 35 is provided with a grip portion 35b for projecting and integral with the cover 35 for rotating the cover 35. In the cross-sectional view of Fig. 9, in the front portion (on the left side in Fig. 9) of the cylindrical filter casing 34, an enlarged diameter portion 47 having a stepped portion 34d and expanding in diameter is provided. The enlarged diameter portion 47 has a structure of the screw portion 37, and the cover member 35 is screwed to the filter case 34 via the screw portion 37 via a water seal gasket 42 made of an elastic body such as rubber. A convex engaging portion 10 35a ' is formed behind the cover 35 (on the right side in FIG. 9), and a concave engaging portion integrally formed therewith and engageable with the convex engaging portion 35a is formed in the filter body 36. 36a. Further, the cover 35 and the filter body 36 are coupled together by the engagement between the convex engagement portions 35a and the concave engagement portions 36a. Therefore, the filter body 36 can be taken out from the filter housing 34, i.e., the body 1 of the washing machine, by rotating the cover 35 away from the threaded portion 37. 15 The filter body % is formed with a cylindrical and mesh-shaped screen portion 51 which allows water to pass but simultaneously intercepts foreign matter. Further, the filter body 36 is disposed inside the filter housing 34 between the inflow port 38 of the filter case 34 and the outflow port %. Thus, the laundry drain containing the foreign matter can pass through the filter portion 51 through the inlet port 38, and then flows from the outlet port 39 through the drain path to the drain line outside the machine 20 in the state of the foreign matter removal. In the filter device of the above configuration, the cover 35 is rotated, and the filter body 36 is taken out from the over-casing casing 34, and the accumulated shoulders and the like are removed. After that, the cover 35 is normally screwed back to the original position on the filter housing 34 to prevent water from leaking out of this portion. 200934915 Therefore, in the above-mentioned conventional example, the following structure is used to prevent water leakage. The cover body 35 is provided with a recessed portion 351 recessed in a cup shape on the side of the cover body ιοί, and the recessed portion 351 is provided with a grip portion 35b protruding from the center of the slightly circular surface of the recessed portion and extending in the diameter direction. Also shown in the perspective view of Fig. 8 is a perspective view. Further, the main body 1 is provided with a locking hole 1〇4 through which the hook member 103 is inserted to be engaged in a portion corresponding to the hook member 1〇3 of the lid body 101. The front view of the lid body 101 of Fig. 10 shows the state when the lid body 1〇1 is properly closed. Here, the center angle 0 indicates the angle at which the grip portion 351) rotates from the reference line 1〇5. That is, when the grip portion 35b is located at a position 10 which is slightly 90 degrees from the center angle 0, the lid body 1〇1 is closed in the direction of the arrow J of Fig. 8. As a result, as shown by the dotted lines in FIG. 9 and FIG. 10, the rib 1〇2 of the cover 1〇1 does not abut the grip portion 35b of the cover 35, and the cover 1〇1 can be completely closed. . At the same time, the hook portion at the front end of the hook member 103 can be locked to the locking hole 1〇4, so that the cover body 101 does not easily open even if an external force is applied from the outside of the washing machine. 15 With respect to the normal installation state, when the central angle 0 of the grip portion 35b is deviated from 90 degrees to 90 degrees, the rib 1〇2 will still abut the grip portion 35b even when the lid body 1 is closed. In turn, the cover 1〇1 cannot be closed. Therefore, it is easy to detect that the cover 35 is not completely mounted due to the lid 101 being not normally closed. Thereby, the user can operate the grip portion 35b again to screw the cover 3520 to the appropriate position, and easily return to the water-free state. That is, the user can determine whether the cover 101 is properly mounted on the body 丨 to prevent water leakage. Further, the related art document information of the invention of the above-mentioned application is known, for example, in Japanese Laid-Open Patent Publication No. 2-282616. However, in the structure of the prior art, it is necessary to determine whether the cover body 35 is correctly installed on the body 1 or the cover, in order to determine whether the cover body 35 is positive or not. Body 101 is in a closed state. However, the 'wan-user's attention is focused on cleaning the foreign matter from the transition body 36, and forgetting to close the cover 101 will not confirm the leakage prevention. Or the 'reduction of the number of parts for the purpose of designing or lowering the cost, so that the structure of the above-mentioned prior art is configured because the filter device including the cover 101 is configured as Since the necessary conditions, the above structure without the cover body cannot be realized. 10 Further, the lid body 101 is generally made of a plastic molding material or the like, and is usually disposed at the lower portion of the washing machine, so that the user and the toe of the family by the washing machine touch the tip of the foot, or the user fails to recognize the cover. When the closing state of the lid body 101 is forcibly pressed, the lid body 1〇1 is broken or the lid body 101 is detached from the washing machine body. Once such a situation occurs, it is of course impossible to confirm whether or not the water leakage is prevented. In addition to these problems, the operation of such washing machines is generally a housewife rather than an expert, so there is still a problem to be solved that must be constructed to be easy to understand and simply prevent water leakage. [Metals and contents] 20 The invention discloses a filter device for solving the above-mentioned conventional problems, which is not affected by the presence or absence of a cover, and can detect the installation state of the cover of the filter device, and is installed. When the setting is incomplete, the user is notified of the abnormal state to achieve water leakage when the washing machine is actually prevented from being used. 200934915 Therefore, the filter device of the washing machine of the present invention includes a cover body that operates the switching state of the filter device when removing foreign matter; and the telecommunication transmission and reception device operates in a normal position on the filter housing on which the cover body is mounted. Moreover, when the cover body is not properly installed, the cover is closed again by the abnormality of the user's disposal. With the foregoing construction, the filtering device of the washing machine of the present invention can prevent water leakage during washing.

I: Embodiment 3 Best Mode for Carrying Out the Invention 9 200934915 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same components as those of the conventional examples will be given the same reference numerals and detailed description thereof will be omitted. In addition, this embodiment is not intended to limit the inventors. (Embodiment 1) 5 The first W is an external view of a washing machine having a bribe according to Embodiment 1 of the present invention. Fig. 2 is a cross-sectional view when the filter is placed, and Fig. 3 is a front view of the filter device when the filter device is incompletely installed, and the 4A to the front side shows the state of the cover of the transition device. The plan view of the operation, the top view shows a partial side view of the operation of the cover installation state of the filter device, and Fig. 6 is a part of the control flow chart of the washing machine. As in the washing machine of Fig. 1, the recess 7 formed below the front surface of the body 1 of the washing machine is provided with a cover 2' which is slightly rounded for operation to remove foreign matter such as debris in the drainage (4) Device. Further, the cover 2 is configured to be movable in the rotational direction, to detach the attachment means, and to move the filter out of the shaft 5. A control device 3 is disposed inside the upper portion of the body 1, and a microcomputer for controlling a series of strokes such as washing and dehydrating is built in. Further, the upper surface I of the main body 1 is provided with a switch unit 4 for inputting the operation stroke input control device 3, a display unit 5 for controlling the state of the on/off state and the remaining time, and the like. Water drain pipe 6. The portion 7 = the cross-sectional view of Fig. 2 is shown. The cover 2 is housed on the fourth body 1 and does not protrude outward from the outline 8 outside the body 1. The front side of the cover body 2 (the left side in Fig. 2) is integrally formed with a word ♦ 旋 'the user can grasp the finger to perform the rotation operation. Further, inside the inside is 20, 200934915 5 Ο 10 15 ❹ 20 1 , a filter body 11 having a mesh filter portion 10 that allows water to pass but intercepts foreign matter to be formed in the concave engagement portion 16 of the filter body 11 The cover portion 15 formed in the cover body 2 is closely attached to the cover member 2 so as to be freely rotatable. Further, the grasping knob 9 such as a finger can be pulled out toward the axial direction of the cover 2, and the filter body 11 can be taken out to the outside of the machine. The cover 2 and the filter body 11 are both housed in the filter housing having the inflow port 12 and the outflow port 13. The inside of the outer peripheral cylindrical portion 17 of the connecting portion on the side of the cover 2 on the side of the casing 11 is attached to the outer periphery of the outer peripheral cylindrical portion 17 of the filter body 11 with a shackle 18 formed of an elastic body such as rubber, which is in close contact with the inclined wall 19 of the filter case 14 Water seal. The drainage of the washing water containing foreign matter such as debris, the foreign matter is removed from the inlet port 12 when passing through the mesh portion 10, and then flows out of the machine through the drain pipe 6 of Fig. 1 from the outlet port 13. On the side of the concave portion 7 of the main body 1 in which the filter case 14 is housed, a large-diameter cylindrical portion 20 integrally formed is housed, and a cover body 2 that is freely rotatable is housed inside the cylindrical portion 20. Further, the inner peripheral portion of the cylindrical portion 2 has a plurality of protrusions 21, and the projections 22 formed on the outer peripheral portion 23 of the cover 2 can be pressed toward the filter body 11 side. Thus, the '0-ring 18 can be pressed toward the inclined wall 19 by the outer peripheral cylindrical portion 17 so that the washing water inside the filter casing 14 is sealed with the outside. The magnetic body 24 is housed in one of the outer peripheral portions 23 of the cover 2, and the mounting plate 25 is integrally formed on the outer peripheral portion of the cylindrical portion 2 of the filter casing. Further, a reed switch 26 is attached to the mounting plate 25 on the outer peripheral portion of the cylindrical portion 20. Here, the reed switch 26 is disposed at a position corresponding to the magnetic body 24, and the inner magnetic corresponding operation portion 27 is disposed at a position where the magnetic body 24 can be closely attached. In the cross-sectional view in which the filter device of Fig. 3 is incompletely installed, as shown in Fig. 11 200934915, the projection 22 of the cover 2 does not enter the inside of the projection 21 of the cylindrical portion 20 of the filter housing 14. In this state, the cover body 2 and the filter body 11 have a 〇-shaped ring 18 or the like disposed therebetween, and the position at the time of mounting as shown in Fig. 2 becomes in the third figure. The outer side of the body i (ie, the left side in Figure 3). 5 Therefore, the water seal effect achieved by the 0-ring 18 or the like disappears and will cause water leakage. At this time, since the magnetic body 24 and the magnetic corresponding operation portion 27 inside the reed switch 26 are displaced by the distance Η in the axial direction, the magnetic corresponding operation portion 27 is not affected by the magnetic body 24 and does not operate. Therefore, since the reed switch 26 does not operate, no ON signal from the reed switch 26 is transmitted to the control device 3. 10A to 4D are plan views showing the operation of the cover mounting state of the filter device, and Fig. 4A shows the preparation position before the cover 2 is mounted. In the fourth embodiment, the position of the reed switch 26 and the magnetic corresponding operation portion 27 in the circumferential direction is attached to the mounting plate 25 which is formed adjacent to the upper portion of the cylindrical portion 20 of the filter housing 14, so that the cover 2 is positive. Up direction (12 o'clock direction). On the other hand, 15 is mounted on the magnetic body 24 of the cover 2 at a position of stone=slightly 90 degrees leftward (9 o'clock direction), and the direction of the one-shape shape of the knob 9 of the cover 2 is set to be slightly vertical . In the preparation position before the cover 2 of the fourth embodiment, the projection 22 formed on the outer peripheral portion 23 of the cover 2 has a stopper portion 30 at one end portion and a width D 20 in the lower portion. Similarly, a second protrusion 22e having a symmetrical shape is provided on the upper side of the opposite side of the 180 degree, and a total of two places are provided in total. The position of the ridge 21 formed on the inner circumference of the cylindrical portion 20 of the filter casing 14 is a distance C from the left end of the width D of the projection 22 of the cover 2 in the direction of rotation. Fig. 4B shows the state in which the cover 2 is rotated clockwise by the knob 9 by about 45 200934915 degrees = about 45 degrees. The projection 22 of the cover 2 becomes a cross-sectional view of the second drawing which follows the ridge 21 of the inner peripheral portion of the cylindrical portion 20 of the filter case 14. However, since the magnetic body 24 and the magnetic corresponding action portion 27 inside the reed switch 26 are offset by an angular direction of about 45 degrees and are spaced apart from each other, the magnetically opposed operating portion 27 does not detect the magnetic body 24. Further, when the cover 2 is rotated by 80 degrees and the state is changed from the 4A to the 4C, the water seal effect of the 〇-shaped ring 18 is first generated. Further, although the magnetic body 24 and the magnetic corresponding operation portion 27 inside the reed switch 26 have an offset of about 10 degrees in the angular direction, the magnetic corresponding operation portion 27 can start detecting the magnetic body 24. Therefore, the reed switch 26 starts to detect the ON state, and the cover 2 and the filter body 11 have the 〇-shaped ring 18 disposed therebetween, and the axial direction of the cross-sectional view of Fig. 2 is obtained. As shown in Fig. 4D, when the knob 9 is rotated by 90 degrees from the state of Fig. 4A, the positional relationship between the magnetic body 24 and the magnetic corresponding action portion 27 inside the reed switch 26 becomes valley = 〇, without Offset in the angular direction. Therefore, the magnetic-corresponding operation unit 27 can reliably detect the magnetic body 24, and the stopper portion 30 can abut the ridge 21 while the reed switch 26 can completely detect the ON state. Thereby, the user can judge that the cover 2 is completely installed. In addition, Fig. 5 is a partial side view showing a portion viewed from the direction of the arrow A in Fig. 4B. The axial relationship between the projection 22 of the cover 2 and the projection 21 of the cylindrical portion 20 of the filter housing 14 will be described with reference to Fig. 5. The projection 22 has three heights of the thin portion 22a, the inclined portion 22b, and the pressing portion 22c in the axial direction from the side of the opening portion 22d in the range of the width D. Further, the gap E formed between the pressing portion 22c and the flange portion 31 is set to be approximately only slightly larger than the thickness dimension 13 of the filter housing 14 13 200934915 F. As the cover 2 rotates, the inclined portion 22b slides with the cover 2, and the cover 2 moves toward the arrow G direction with respect to the fixed side protrusion 21, so that the outer circumference of the filter body 11 of FIG. 2 is pressed. The portion π causes the water seal effect of the 〇-shaped ring 18 to be achieved. 5 The K point of the final part of the inclined portion 22b is set to be changed to the coldness of the 4Cth diagram = slightly 10 degrees, and the water seal effect of the 〇-shaped ring 18 is generated first from the ON action of the reed switch 26" As shown in FIG. 4A, when the knob 9 is slightly inserted perpendicularly from the arrangement in which the ridge 21 and the pressing portion 22c do not interfere with each other in the planar state, the pressing ◎ 10 portion 22c changes from the ridge 21 On the side of the filter body 11. At this time, when the knob 9 is rotated, as shown in Fig. 2, the 〇-ring 18 can be correctly pressed and the reed switch 26 is also operated. However, for example, when the filter cartridge is inserted into the filter housing 14 in a horizontal state, the ridge 21 and the pressing portion 22c will interfere with each other. Therefore, even if the magnetic body 24 and the magnetic corresponding action portion 27 are close to each other in plan view, the incomplete state of the third figure is formed, and the axial offset of the distance Η is obtained, so that the signal is not transmitted to the control. Device 3. As described above, the reed switch 26 is turned ON only when the magnetic body 24 and the magnetic corresponding operation portion 27 are aligned in the rotational direction and the axial direction of the cover 2''. Thereby, the normal installation of the cover 2 is input from the signal line 28 20 to the control device 3. Next, with reference to Fig. 6, a description will be given of a control flow of the washing machine when the user wants to perform the laundry operation operation if there is no signal from the reed switch 26, that is, when the filter device is incompletely installed. First, the user puts clothes and lotion into the predetermined position of the washing machine, 14 200934915 and puts the power switch in the 〇N state (s1〇〇), and then sets the desired running stroke (S1〇1). Then, the start switch is turned ON and input (S102), and in the next step (Si〇3), whether or not the reed switch 26 of the filter unit has a round-in signal to determine whether it is in an ON state or a 〇FF state. 5 At this time, if it is in the 〇N state, the washing machine will start to operate (S104), and perform a series of steps such as washing, rinsing, and dehydration. If the reed switch 26 is in the 〇1^ state, as shown in Fig. 6, the stop step is performed, and the abnormality notification is immediately entered (S105). ◎ When the time value is displayed, the display unit 5 of the figure will display, for example, the "closed 10 filter unit" which represents the "abnormal notification that can be repaired by the user's operation", which is set in advance, and urges the user to pay attention, and the washing machine Will not work. Then, it is checked whether the user performs the repair operation and the filter device is installed normally. Once this is the case of 'returning again to the step of confirming that the reed switch 26 is in the ON state or the 0FF state (S103), if the reed switch 26 is in the ON state, the operation is started without re-operation (S104), and the washing step is started. . In other words, the filter device of the washing machine of the present invention comprises a filter body H 11 ' disposed on the drainage path to intercept foreign matter such as debris; and the cover body 2 having a knob for operating the filter body 11 in the rotation direction and the axial direction; The filter housing 14' includes the filter body 11 and the cover 2 therein. Further, the filter device further includes a reed switch 26 attached to the filter case 14 and a magnetic body 24 attached to the position where the cover 2 corresponds to the reed switch 26. Further, the filter device further includes a 〇-shaped ring 18, a water seal formed between the filter body 11 and the filter housing 14, and a control device for controlling the washing machine and the display portion. Further, the outer periphery of the cover 2 is provided with a projection 22' having a thickness varying in the axial direction, and a projection 21 corresponding to the projection 15 200934915 22 is provided on the inner circumference of the cylindrical portion 20 of the filter housing 14, and the projection 22 can be pressed. Thereby, the water seal between the filter housing 14 and the cover 2 is obtained. The ( can be pressed against the 〇-shaped ring 18 to form a position in the direction and the axial direction of the cover body 2 when the wei wei 24 attached to the cover body 2 is located. When the position is corresponding to the position of the reed switch 26, the tongue (4) (4) will be in a 5 ON state. . At the beginning of the step, the signal is input without the ON signal input from the reed switch %. (4) The device 3 stops the step. At this time, an abnormality notification is made on the display unit 5, for example, when the user of the washing machine is notified, and the cover member 2 is in an inoperative position in the circumferential direction, the filter housing positioning position cannot be inserted in the axial direction. At this time, the reed switch 26 does not operate. 10, the other side, when the position of the cover 2 is in the predetermined circumferential direction, by rotating the knob 9, the action of pressing the Ο-shaped ring 18 and causing the tongue to open (4) in the state of (10) can be completed. Moreover, although the operation signal of the washing machine has been input but the signal from the reed switch 26 has not been received, the control device 3 will distinguish the abnormality notification that the display cover 2 is not properly installed, such as the washing machine. Notification of disposition. Therefore, the user is known as an abnormal notification, but the user knows that it is a notification and a treatment that can be easily corrected. Therefore, the filter device is extremely easy to discriminate and easy to handle for the user. The filter device of the washing machine configured as described above will be described below in terms of its operation, action, and effect. When the cover 2 is not in the predetermined position in the circumferential direction, that is, the positional relationship shown in the cross-sectional view when the mounting of FIG. 3 is incomplete, it is not possible to insert the predetermined position in the filter housing 14 in the axial direction. In addition, in the axial direction between the magnetic body 24 in the cover 2 and the magnetic corresponding action portion 27 in the reed switch 26, 200934915

D. Since the operation signal of the washing machine has been input but the signal from the reed switch 26 has not been received, the control device 3 performs an abnormality notification of the installation failure 5, and displays the preset representative "through the user. _ "Close the filter, the part" of the "Can be repaired abnormal notification". That is, the difference is different from the general failure, and the notification and disposal that the user can easily correct are displayed. Then, when the filter device returns to normal, the operation is started immediately without re-switching, so it is a simple and extremely easy-to-handle structure for the user. When the cover 2 is installed, the rotation of the cover 2 is performed, and the knob 9 is first inserted in the vertical direction and then inserted in the axial direction, and then rotated within a range of a slight angle of 90 degrees from the installation of the filter device to the mounting element. . In addition, when the final position is reached, the stopper portion 30 abuts against the ridge 21, so that it can be felt that the cover 2 is mounted. Therefore, it can be said that it is easy to handle, and the rotational force of the user's finger is easily applied to the cover 2 to be surely operated. That is, when the operation of the rotation of the knob 9 is performed, the reed switch 26 is set to be in an ON state after the water sealing action by the cymbal ring 18 is completed. Thereby, the rotation operation of the cover 2 is performed. The knob 9 is first inserted into the vertical direction in the vertical direction, and when the final position is reached, the stopper 30 abuts against the protrusion 21, so that the cover can be felt. 2 installed. Therefore, the rotational force of the user's finger is easily applied to the cover 2 and can be surely operated, which is easy to operate. Further, foreign matter such as debris accumulated in the filter device must be periodically removed. To this end, when the knob 9 is operated to take out the filter body u from the filter housing 14, the foreign matter or the like is usually dropped to the inner and outer circumferences below the cylindrical portion 20 of the filter housing 14. In the present filter device, since the reed switch 26 is attached to the mounting plate 25 formed on the outer periphery of the cylindrical portion 2, the reed switch 26 is located above the cylindrical portion 20, and the washing water does not drip into the electrical member. The reed switch 26 is divided into 5 points, of course, it will not lead to a lack of safety such as short circuit and insulation degradation. In other words, the reed switch 26 is disposed above the filter body 11. Thereby, when the operation knob 9 is operated to take out the filter body 11 from the filter housing 14, the laundry water droplets contained in the foreign matter or the like fall into the inner and outer circumferences below the cylindrical portion 2 of the filter housing 14, and the safety is not caused. Missing. The reason for this is that the reed switch 26 is attached to the mounting plate 25 formed on the outer periphery of the cylindrical portion 20. The washing water does not drip into the reed switch 26 of the electrical component, and of course, it does not cause safety problems such as short circuit and insulation deterioration. As described above, in the first embodiment, only when the cover 2 is correctly placed in the rotational direction and the axial direction of the cover 2, the signal is transmitted to the control device 3, and the operation of the cover 2 is performed. It can also be carried out within a slight 90 degrees. Further, in the event of an abnormal state, the user is notified of an abnormal alarm that is easy to understand. Therefore, the filtering device of the present invention simplifies the leakage prevention during washing and is easy to use. In the filter device of the washing machine of the present invention, it is easy for the operator to carry out the loading and unloading operation of the 20-line filter device, and the foreign matter in the drain is periodically removed by hand. In addition, the filter device of the present invention can be applied to the washing machine as a representative of the washing machine because the structure can notify the abnormality of the water leakage caused by the incomplete installation during the loading and unloading operation. It is very useful to have a machine for draining foreign matter. 200934915 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an external view of a washing machine having a filtering device according to an embodiment 1 of the present invention.
