And extended, the front end of the discharge side of the circulation flow path member is located near the convex portion. [Effects of the Invention] According to the present invention, it is possible to provide a washing machine capable of appropriately circulating washing water with a simple configuration.

[0010] 以下，作為其中一例，針對進行洗衣、洗清、脫水之洗衣機100(所謂的全自動洗衣機：參考圖1)作說明。 　　[0011] 實施形態 　　圖1，係為對於實施形態的洗衣機100之內部構成作展示的概略圖。 　　圖1中所示之洗衣機100，係為進行衣物之洗滌等的機器，並主要具備有洗衣槽10、和攪拌翼20、和外槽30、和驅動裝置40、和控制單元50、和平衡環60(流體平衡器)、和循環流路構件70、80、以及外框90。另外，在圖1中，針對另外一方之循環流路構件80(參考圖3A)，係並未作圖示。 　　[0012] 洗衣槽10，係為收容洗滌物R者，並呈現有底圓筒狀。洗衣槽10，係具備有圓筒狀之胴體板11(洗衣槽10之周壁)、和將此胴體板11之下部作閉塞之底板12。在胴體板11處，係被設置有複數之用以藉由伴隨著洗衣槽10之旋轉所產生的離心力來將在洗滌物R中所包含之洗衣水脫水的脫水孔h1(在圖1中，係對其之一部分作圖示)。 　　[0013] 攪拌翼20(脈動翼盤、亦稱作脈動器)，係呈現略圓盤狀，並被設置在洗衣槽10之底部。又，攪拌翼20，係藉由驅動裝置40而被可旋轉地作軸支持。而，在進行洗滌或洗清時，係成為藉由使攪拌翼20旋轉而將洗衣水與洗滌物R一同作攪拌。 　　[0014] 外槽30，係呈現有底圓筒狀，並將洗衣槽10於同軸上(亦即是，中心軸為略同一之狀態)而作內包。外槽30，係經由線圈彈簧或彈性橡膠等之防震裝置G，而從外框90之上端附近垂吊下來。在外槽30之底部，係被設置有用以將洗衣水排水之排水口ha。此排水口ha，係經由排水閥V1而被與排水管H1作連接。 　　[0015] 驅動裝置40，係具備有使攪拌翼20旋轉之馬達和減速機構，並且，雖並未圖示，但是亦具備有離合器，並經由安裝基體B而被安裝在外槽30之底部外側。而，在進行洗滌時或洗清時，前述之馬達的旋轉係經由離合器而被傳導至攪拌翼20處，並成為在使洗衣槽10靜止了的狀態下而使攪拌翼20進行正逆旋轉。又，在脫水時，藉由馬達之驅動，洗衣槽10以及攪拌翼20係成為一體性地高速旋轉。 　　[0016] 控制單元50，係具備有對於驅動裝置40等之機器作控制的功能，並被設置在外框90之上部。 　　平衡環60，係為於內部封入有流體(鹽水等)之外形環狀的流體平衡器。平衡環60，係具備有當在洗衣槽10的旋轉時起因於洗滌物R之偏移等而產生了偏心時，藉由前述之流體的移動來將偏心抵消並維持旋轉之平衡的功能。 　　[0017] 循環流路構件70，係為將伴隨著攪拌翼20之旋轉而被推壓流動的洗衣水導引至上方並吐出的板狀之構件，並被設置在洗衣槽10之胴體板11的內周面。另外，關於循環流路構件70之詳細內容，係於後再作記載。 　　[0018] 外框90，係為收容前述之各構件的框體，並呈現箱狀。外框90，係於其之下部具備有基體構件91，又，係於上部具備有上面罩92。在上面罩92之中央部，係被設置有用以使洗滌物R進出的洗滌物投入口hb，在此洗滌物投入口hb處，係被設置有可作開閉之蓋體93。 　　[0019] 又，在洗衣槽10之外周面與外槽30的內周面之間，係存在有空隙。以不會使洗滌物R進入此空隙中的方式，而設置有將前述之空隙從上方來作覆蓋的槽罩C。除此之外，洗衣機100，係具備有供水管H2、電磁供水閥V2，並且亦具備有感壓式之水位感測器S等。 　　[0020] 例如，在進行洗衣或洗清時，藉由控制單元50之指令，電磁供水閥V2係被開啟，並經由供水管H2對於外槽30內供給洗衣水。而，若是基於水位感測器S之檢測值而偵測到係成為了特定之水位，則藉由控制單元50，電磁供水閥V2係被關閉，供水係停止。又，在進行脫水時，藉由控制單元50，排水閥V1係被開啟，外槽30內之洗衣水係經由排水管H1而被排出。 　　[0021] 圖2，係為實施形態的洗衣機100所具備之洗衣槽10等的縱剖面圖。另外，在圖2中，係將脫水孔h1(參考圖1)之圖示省略。 　　圖2中所示之底板12，係為將胴體板11之下部閉塞的皿狀之構件，並被固定在胴體板11之下端。底板12，係具備有構成洗衣槽10之底面之底部12a、和從此底部12a之外周緣起而朝向上側延伸並構成洗衣槽10之側面的一部分之側部12b。另外，在底部12a處，係被設置有複數之與外槽30側相通連之孔hc。 　　[0022] 攪拌翼20，係為覆蓋底板12之略圓盤狀之構件。攪拌翼20，係以使直徑方向之中心附近朝向上側***的方式而被形成，並且周緣附近係沿著周方向而朝向上下來如同波浪一般地彎曲。在攪拌翼20處，除了孔hd之外，亦被設置有複數之圓形之凹坑部21和朝向直徑方向延伸之突條部22。 　　[0023] 被設置在胴體板11之內周面的循環流路構件70，係如同前述一般，為將伴隨著攪拌翼20之旋轉而被推壓流動的洗衣水導引至上方並吐出的構件。循環流路構件70，係呈現於縱方向上而為細長的板狀，在橫剖面觀察下，係朝向與胴體板11之內周面相反側而彎曲。 　　[0024] 在循環流路構件70之裡面，雖並未圖示，但是，係於循環流路構件70之周方向的兩端附近，設置有朝向縱方向而延伸之一對的肋。而，在將循環流路構件70藉由螺絲鎖合來固定於胴體板11處時，前述之肋係與胴體板11作碰觸抵接並撓折，而成為密著於胴體板11上。藉由此，係能夠使循環流路構件70之周方向的兩端附近密著在胴體板11之內周面上。 　　[0025] 又，循環流路構件70之下端、上端，係並未密著於胴體板11上地而作開口。又，係成為經由循環流路構件70之裡面與胴體板11之內周面之間的空隙(以下，稱作「循環流路P」，參考圖1)，來藉由攪拌翼20之旋轉而將洗衣水朝向上方揚水。亦即是，洗衣水，係經由循環流路P而被從洗衣槽10之底部來上推至上部，並進而成為經由吐出口he而使洗衣水回到洗衣槽10之內部。另外，在本實施形態中，係以洗衣槽10之中心軸O作為基準來相互對向地而設置有一對的循環流路構件70(參考圖7A)。 　　[0026] 又，在胴體板11之內周面，係相對於循環流路構件70來在周方向上設置90°之間隔地而設置有其他種類之循環流路構件80。針對此循環流路構件80，使用圖3A來作說明。 　　[0027] 圖3A，係為實施形態的洗衣機100所具備之洗衣槽10等的縱剖面圖。另外，在圖3A中，係對於在將攪拌翼20卸下了的狀態之洗衣槽10中而從正面來對於循環流路構件80作了觀察的縱剖面圖作展示。 　　如同圖3A中所示一般，循環流路構件80，係具備有基部81、和絲屑收集部82。基部81，係為使其之上端附近以及周方向之兩端附近密著於胴體板11之內周面上的板狀構件。雖並未圖示，但是，基部81，係具備有與絲屑收集部82相對應之形狀的開口。又，在基部81之下端附近，係設置有用以將經由攪拌翼20之旋轉而被推壓流動的洗衣水導入之流入口hf。 　　[0028] 絲屑收集部82，係為用以將絲屑等作收集的裝卸式之構件，並被裝著在前述之基部81的開口(未圖示)處。在絲屑收集部82處，係被設置有複數之孔hg，在此些之孔hg的區域處，係被貼附有綿絨濾網(未圖示)。又，在複數之孔hg之上側，係被設置有用以將洗衣水吐出之吐出口hi。 　　[0029] 經由流入口hf而流入了的洗衣水，係經由循環流路構件80與胴體板11之間的空隙(以下，稱作「循環流路Q」，未圖示)而被上推。而，在洗衣水於前述之循環流路Q中而流動的過程中，藉由絲屑收集部82，絲屑等係被收集，進而，經由吐出口hi，洗衣水係回到洗衣槽10內。 　　[0030] 另外，係亦可並非在前述之吐出口hi處設置絲屑收集部82，而是構成為在基部81之上端附近處設置細縫狀之吐出口。又，在本實施形態中，係以洗衣槽10之中心軸O作為基準來相互對向地而設置有一對的循環流路構件80、80(參考圖7A)。 　　[0031] 圖3B，係為圖3A中所示之虛線J的範圍之部分擴大圖。 　　如同圖3B中所示一般，洗衣槽10，係在此洗衣槽10之周壁之邊緣11b(端緣)附近，具備有朝向直徑方向內側而突出之凸狀部11a。另外，係涵蓋洗衣槽10之周壁之全周地而被形成有凸狀部11a，在此凸狀部11a之上側係設置有平衡環60。 　　[0032] 若是針對平衡環60之設置更進一步作詳細說明，則在使平衡環60被載置在凸狀部11a上的狀態下，洗衣槽10之周壁之邊緣11b附近係被朝向直徑方向內側作彎折。藉由此種捲邊作業，係成為使前述之邊緣11b附近密著於被設置在平衡環60之外周壁處的肋61之上面。 　　另外，凸狀部11a，係亦具備有在脫水時對於洗衣槽10起因於離心力而朝向直徑方向外側變形的情形作抑制並確保其之強度的功能。 　　[0033] 如同圖3B中所示一般，凸狀部11a，係具備有第1傾斜面K1。第1傾斜面K1，係以若是在洗衣槽10之軸方向上而越接近周壁之邊緣11b(亦即是，若是其之高度越高)則與洗衣槽10之中心軸O(參考圖3A)之間的直徑方向上之距離會變得越短的方式，而作傾斜。此第1傾斜面K1，係為用以將經由循環流路P而被朝向上方上推的洗衣水導引至傾斜方向(成為使洗衣水隨著上升而朝向直徑方向內側前進)的傾斜面。 　　[0034] 又，循環流路構件70之吐出側，係朝向洗衣槽10之軸方向(在圖3B中，係為鉛直方向)而延伸。故而，例如，相較於將循環流路構件70之吐出口he附近朝向直徑方向內側而彎折的構成(參照圖6B之比較例)，係能夠對於洗衣水之循環流量的降低作抑制。 　　[0035] 又，如同圖3B之横方向之虛線所示一般，循環流路構件70之吐出側的前端70a，係一直延伸至洗衣槽10之凸狀部11a的附近(在圖3B所示之例中，係為較凸狀部11a之前端而更些許下側)處。藉由此，係能夠抑制洗衣水之循環流量的降低，並且能夠將洗衣水朝向與凸狀部11a之第1傾斜面K1相平行的方向作導引。 　　[0036] 另外，循環流路構件70之吐出側的前端70a，若是相對於凸狀部11a而離開特定距離以上地位置於下側處，則洗衣水在到達凸狀部11a之前便從循環流路構件70而流下的可能性係變高。 　　另一方面，循環流路構件70之吐出側的前端70a，若是相對於凸狀部11a而離開特定距離以上地位置於上側處，則平衡環60與循環流路構件70之前端70a之間的距離係會變得過短，流露阻抗係變大，而會導致洗衣水之循環流量的降低。故而，如同前述一般，較理想，循環流路構件70之吐出側之前端70a，係位置在凸狀部11a之附近。 　　[0037] 又，平衡環60，係於其之內周面的下部而在凸狀部11a之近旁處具備有第2傾斜面K2。第2傾斜面K2，係為用以將沿著凸狀部11a之第1傾斜面K1而朝向斜方向流出的洗衣水更進而朝向略相同方向而導引的傾斜面。此第2傾斜面K2，係與凸狀部11a之第1傾斜面K1成為略同一平面，並位置於較凸狀部11a而更靠直徑方向內側。 　　另外，第2傾斜面K2和循環流路構件70之前端70a之間的距離L1，係以不會對於經由循環流路P所被上推的洗衣水之流動造成阻礙的方式，而被適宜作設定。 　　[0038] 又，如同以圖3B之縱方向之虛線所示一般，第2傾斜面K2，係在縱剖面觀察(於包含有洗衣槽10之中心軸O的平面處之縱剖面，參考圖3A)下，而存在於循環流路構件70之吐出側之延長線上。藉由此，以特定之流量而被朝向上方作了上推的洗衣水，係成為沿著第2傾斜面K2而被吐出。 　　[0039] 進而，平衡環60，係於較第2傾斜面K2而更靠直徑方向內側，具備有使洗衣水與自身作碰撞並擴散的擴散面K3。在圖3B所示之例中，擴散面K3，係成為相對於洗衣槽10之中心軸O而相垂直的平面(亦即是，水平面)。藉由此，來使沿著第1傾斜面K1以及第2傾斜面K2而流出了的洗衣水與擴散面K3相碰撞，而能夠涵蓋洗衣槽10內之廣範圍地來使洗衣水擴散。 　　[0040] 圖4，係為對於洗衣機100所具備之攪拌翼20的裡側作展示之立體圖。 　　如同圖4中所示一般，攪拌翼20，係於其之裡面(下面)，具備有從中心軸O起而朝向直徑方向來以輻射狀作延伸之複數之裡扇葉。裡扇葉23，係在周方向上以等角度之間隔而被作配置。 　　[0041] 若是作更詳細之說明，則於在攪拌翼20之上方(在對於攪拌翼20之裡側作展示的圖4中，係為下方)處而***了的2個的區域之裡面，係被形成有裡扇葉群23A、23A。各個的裡扇葉群23A，係藉由5枚的裡扇葉所構成，並在周方向上而被配置於約90度的角度範圍內。裡扇葉群23A，係具備有將作循環之洗衣水導入的功能和對於攪拌翼20之撓折變形作抑制的功能。 　　[0042] 在裡扇葉群23A、23A之間，係被設置有其他的裡扇葉群23B、23B。此些之裡扇葉群23B、23B，係被形成於在攪拌翼20之下方(在對於攪拌翼20之裡側作展示的圖4中，係為上方)處而凹陷之2個的區域之裡面。裡扇葉群23B，係由3枚的裡扇葉23所構成，並具備有對於攪拌翼20之撓折變形作抑制的功能。 　　[0043] 在攪拌翼20之裡面的中心附近處，係被形成有被與中心軸O形成為同心圓狀之3個的圓環肋24。此些之圓環肋24，係具有對於裡扇葉群23A、23A、23B、23B作補強的功能。 　　[0044] 進而，在攪拌翼20之裡面，於周方向上而延伸之外周側肋25以及內周側肋26、27，係在直徑方向上設置有特定間隔地而被形成。外周側肋25以及內周側肋26、27，係分別以與攪拌翼20之曲率略相同的曲率而彎曲。 　　[0045] 外周側肋25，係為位置於攪拌翼20之外周側的周方向肋。外周側肋25，係從裡扇葉群23A之周方向的其中一端之裡扇葉23起而至另外一端之裡扇葉23地而延伸，並被與此些之裡扇葉23一體性地形成。 　　[0046] 內周側肋26、27，係為位置於較外周側肋25而更靠內周側的周方向肋。內周側肋26、27，係被與裡扇葉群23A之5枚的裡扇葉23中之中央之3枚的裡扇葉23一體性地形成。 　　[0047] 圖5，係為對於洗衣機100之循環流路P的流入口hj與外周側肋25、內周側肋26、27之間的位置關係作展示之縱剖面圖。另外，圖5，係對於當從正面來對於裡扇葉群23A(參考圖4)之被包含於5枚的裡扇葉23中的中央之裡扇葉23而作了觀察的縱剖面圖作展示。 　　[0048] 在循環流路構件70之下側(洗衣槽10之底部附近)，係被設置有將洗衣水導引至循環流路P處之流入口hj。又，洗衣槽10之內底部與攪拌翼20之裡扇葉23之間的空隙，係成為泵室M。而，經由泵室M而被朝向直徑方向外側作推壓流動的洗衣水，係成為經由流入口hj以及循環流路P而被朝向上方作揚水。 　　[0049] 在攪拌翼20之外周緣部，係被形成有朝向流入口hj而朝下側延伸的垂下部28。又，在垂下部28與循環流路構件70之間，係被設置有特定之空隙hk。此空隙hk之尺寸，係被設定為不會使攪拌翼20與循環流路構件70相接觸之程度的距離。 　　[0050] 在將洗滌物R(參考圖1)投入至如此這般所構成之洗衣機100中的狀態下，若是電源開關(未圖示)係被切換為ON，並且開始鍵(未圖示)進而被按下，則藉由控制單元50(參考圖1)，各機器係被作控制。亦即是，電磁供水閥V2(參考圖1)係被作控制並一直被供水至特定之水位，並移行至洗衣工程。在洗衣工程中，藉由驅動裝置40(參考圖1)，攪拌翼20例如係以右旋轉、停止、左旋轉、停止的順序而旋轉。藉由此，洗滌物R係被與洗衣水一同作攪拌，洗滌物R係成為被洗淨。 　　[0051] 〈作用、效果〉 　　圖6A，係為對於在實施形態的洗衣機100中之經由循環流路P所進行的洗衣水之流動作展示之縱剖面圖。另外，留白箭頭之大小，係代表在循環流路P中所流動之洗衣水的流量之大小(圖6B亦為相同)。 　　經由循環流路P而上升的洗衣水，係在吐出口he附近，沿著凸狀部11a之第1傾斜面K1以及平衡環60之第2傾斜面K2，而被導引至傾斜方向(成為使洗衣水隨著上升而朝向直徑方向內側前進之方向)。之後，起因於洗衣水與平衡環60之擴散面K3相碰撞一事，洗衣水係朝向直徑方向內側前進，在平面觀察下，洗衣水係在洗衣槽10內之廣範圍中而被散水。 　　[0052] 如同前述一般，循環流路構件70之吐出側，係在軸方向上而一直延伸至凸狀部11a之附近為止。亦即是，在循環流路構件70之吐出側處，係並未設置有如同接下來所說明的比較例一般之鍔緣71A(參考圖6B)。故而，由於係幾乎不會有起因於循環流路構件70而導致洗衣水之流動被妨礙(流速下降)的情形，因此，攪拌翼20(參考圖5)之旋轉速度係不會過度提昇，而能夠確保充分的循環流量。 　　[0053] 圖6B，係對於在比較例之洗衣機中的經由循環流路P所進行的洗衣水之流動作展示之縱剖面圖。 　　圖6B中所示之比較例，係在循環流路構件70A之吐出口hm附近設置有鍔緣71A，在此點上，係與本實施形態(參考圖6A)相異。此鍔緣71A，係為將循環流路構件70A之吐出側的前端附近朝向直徑方向內側而作了彎折的部分。又，比較例，在平衡環60A之下部係並未設置有第2傾斜面K2(參考圖6A)，在此點上，係與本實施形態相異。 　　[0054] 在圖6B所示之構成中，經由循環流路P而被朝向上方作了推壓流動的洗衣水，係經由鍔緣71A與平衡環60A之間的空隙而朝向直徑方向內側。於此，鍔緣71A與平衡環60A之間的空隙，由於係使縱方向之寬幅作了縮窄，而流路阻抗係為較大，因此，導致洗衣水之流量之降低的可能性係為高。 　　[0055] 亦即是，若是鍔緣71A之高度降低，則洗衣水進入至鍔緣71A與平衡環60A之間之空隙中的可能性係變高，又，洗滌物R係會與鍔緣71A相碰撞而變得容易受傷。 　　[0056] 相對於此，在圖6A所示之本實施形態中，由於循環流路構件70之吐出側係朝向軸方向而延伸，因此，在循環流路構件70之前端附近，洗衣水之流路係被開放。故而，係幾乎不會有起因於循環流路構件70而導致洗衣水之流動被妨礙的情形。 　　[0057] 例如，假設圖3B中所示之距離L1(循環流路構件70之前端70a與第2傾斜面K2之間之距離)，係與比較例之圖6B中所示之距離L2(鍔緣71A與平衡環60A之間的距離)相同，又，攪拌翼20(參考圖2)之旋轉速度亦為相同。就算是在此種情況，亦同樣的，本實施形態之洗衣水的循環流量，相較於比較例係會變大。此係因為，如同前述一般，在循環流路構件70之前端70a(參考圖3B)之附近，洗衣水之流路係被開放之故。 　　[0058] 又，沿著凸狀部11a之第1傾斜面K1以及平衡環60之第2傾斜面K2，洗衣水係被推壓流動，並進而強力地與平衡環60之擴散面K3相碰撞。藉由此，在平面觀察下，洗衣水係在洗衣槽10內之廣範圍中而被散水。 　　[0059] 又，本實施形態，係並非為如同前述之專利文獻1一般之複雜的構成，而是成為簡單的構成，並成為藉由洗衣槽10、循環流路構件70以及平衡環60之形狀，來將洗衣水導引至特定之方向。進而，也不需要在洗衣槽10之內周面上，另外設置將洗衣水導引至特定之方向的整流肋(未圖示)。藉由此，係能夠將在洗衣機100之製造中所需要的程序和成本降低。又，係能夠防止絲屑等進入至循環流路構件70之空隙中的情形。 　　[0060] 圖7A，係為對於在實施形態的洗衣機100之洗衣槽10中之洗衣水被散水的範圍作展示之平面圖。另外，在圖7A中，係將平衡環60之圖示作省略(圖7B亦為相同)。 　　如同前述一般，在本實施形態中，洗衣水之流速係幾乎不會降低，經由吐出口he，洗衣水係被散水至洗衣槽10中。其結果，由於洗衣水被散水之距離係成為較比較例(參考圖6B)而更長，因此，在平面觀察下，洗衣水係涵蓋洗衣槽10之略全區域(斜線部分之區域U)地而被散水。藉由此，由於洗衣水係從洗滌物R(參考圖1)上而如同沐浴一般地被散水，因此，在洗衣時等之清洗不均的情形係降低，而能夠將洗衣性能提高。 　　[0061] 圖7B，係為對於在圖6B之比較例的洗衣機之洗衣槽10A中之洗衣水被散水的範圍作展示之平面圖。 　　在比較例之構成(參考圖6B)中，如同前述一般，在鍔緣102與平衡環60A之空隙處，洗衣水之流速係降低。其結果，如同圖7B中所示一般，在平面觀察下，係存在有並未被散水有洗衣水之區域。具體而言，在將循環流路構件80、80作連結之直線狀的空隙(斜線部分之區域U1、U2之間之空隙)中，並未被散水有洗衣水之可能性係為高。 　　[0062] 相對於此，若依據本實施形態，則如同前述一般，從吐出口he(參考圖7A)所吐出了的洗衣水，在平面觀察下係被散水至洗衣槽10之略全區域中。故而，係能夠經由循環流路P(參考圖6A)而使洗衣水適當地作循環。 　　[0063] ≪變形例≫ 　　以上，雖係針對本發明之洗衣機100而基於實施形態來作了說明，但是，本發明係並不被限定於此些之記載，而能夠進行各種的變更。 　　例如，在實施形態中，雖係針對平衡環60為具備有第2傾斜面K2(參考圖3B)以及擴散面K3(參考圖3B)之構成來作了說明，但是，係並不被限定於此。亦即是，平衡環60，係亦可為並不具備有第2傾斜面K2以及擴散面K3中之其中一方或者是雙方的構成。就算是在此種構成下，亦能夠以簡單之構成，來經由循環流路P(參考圖3B)而使洗衣水適當地作循環。又，代替平衡環60，例如，係亦可設置圓環狀之框體。 　　[0064] 又，在實施形態中，雖係針對第1傾斜面K1、第2傾斜面K2以及擴散面K3為在縱剖面觀察下而呈現直線狀之構成來作了說明(參考圖3B)，但是，係並不被限定於此。亦即是，第1傾斜面K1、第2傾斜面K2以及擴散面K3中之至少其中一個，係亦可為在縱剖面觀察下而呈現曲線狀之構成。 　　[0065] 又，在實施形態中，雖係針對在縱剖面觀察下而於循環流路構件70之吐出側之延長線上存在有第2傾斜面K2之構成來作了說明(參考圖3B)，但是，係並不被限定於此。例如，在縱剖面觀察下之循環流路構件70之吐出側之延長線與平衡環60之間的交點，係亦可為位於較第2傾斜面K2而更靠直徑方向內側。 　　[0066] 又，在前述之實施形態中，雖係針對具備有2個的循環流路構件70、70和其他種類之循環流路構件80、80的構成而作了說明(參考圖7A)，但是，係亦可對此些之各構件的個數適宜作變更。 　　又，在實施形態中，雖係針對進行洗衣、洗清、脫水之洗衣機100來作了說明，但是，係並不被限定於此。例如，係亦可對於除了洗衣、洗清、脫水之外亦進行烘乾的洗衣烘乾機，而適用本實施形態。 　　[0067] 又，實施形態，係為為了對於本發明作易於理解之說明而作了詳細記載者，本發明係並不被限定於包含有所說明了的全部之構成者。又，係可針對實施形態之構成的一部分，而進行其他之構成的追加、削除、置換。 　　又，前述之機構或構成，係代表被視為在進行說明時所需要者，而並非絕對會對於製品上之全部的機構或構成作標示。[0010] Hereinafter, as one example, a washing machine 100 (a so-called fully automatic washing machine: refer to FIG. 1) that performs washing, washing, and dehydration will be described. [0011] Embodiment FIG. 1 is a schematic diagram showing an internal configuration of a washing machine 100 according to an embodiment.

In addition, in FIG. 1, the other circulation flow path member 80 (refer FIG. 3A) is not shown. [0012] The laundry tank 10 is a person holding the laundry R, and has a bottomed cylindrical shape. The washing tub 10 is provided with a cylindrical carcass plate 11 (peripheral wall of the washing tub 10) and a bottom plate 12 which closes the lower part of the carcass plate 11. At the carcass plate 11, a plurality of dewatering holes h1 (in FIG. 1, for dehydrating the washing water contained in the laundry R by the centrifugal force generated by the rotation of the washing tub 10) are provided. Part of it is illustrated). [0013] The stirring wing 20 (pulsating wing disk, also referred to as a pulsator) is slightly disc-shaped, and is disposed at the bottom of the washing tub 10. The stirring blade 20 is rotatably supported by a shaft by a driving device 40. When washing or washing, the washing water and the laundry R are stirred together by rotating the stirring blade 20. [0014] The outer tub 30 has a bottomed cylindrical shape, and the laundry tub 10 is coaxially mounted (that is, the central axis is in a slightly same state) as an inner package. The outer groove 30 is suspended from the vicinity of the upper end of the outer frame 90 via a shockproof device G such as a coil spring or elastic rubber. A drain port ha is provided at the bottom of the outer tub 30 to drain laundry water. This drain port ha is connected to the drain pipe H1 via a drain valve V1. [0015] The driving device 40 is provided with a motor and a reduction mechanism for rotating the stirring blade 20, and although not shown, it also includes a clutch and is mounted on the outside of the bottom of the outer tank 30 via the mounting base B. When washing or washing, the rotation of the motor is transmitted to the stirring blade 20 via the clutch, and the stirring blade 20 is rotated forward and backward while the washing tub 10 is stationary. In addition, during dehydration, the washing tank 10 and the stirring blade 20 are integrated and rotated at a high speed by the motor. [0016] The control unit 50 is provided with a function for controlling a device such as the drive device 40, and is provided above the outer frame 90. The gimbal ring 60 is a fluid balancer having an outer ring shape in which a fluid (brine, etc.) is sealed inside. The balance ring 60 is provided with a function to offset the eccentricity and maintain the balance of the rotation by the movement of the fluid when the eccentricity occurs due to the deviation of the laundry R or the like during the rotation of the washing tub 10. [0017] The circulation flow path member 70 is a plate-shaped member that guides the washing water that is pushed and flowed along with the rotation of the stirring blade 20 to the top and spit out, and is installed on the carcass plate 11 of the washing tub 10. Inner peripheral surface. The details of the circulation flow path member 70 will be described later. [0018] The outer frame 90 is a frame body that houses the aforementioned components and has a box shape. The outer frame 90 is provided with a base member 91 at a lower portion thereof, and is provided with an upper cover 92 at an upper portion. The center part of the top cover 92 is provided with a laundry input port hb for allowing the laundry R to come in and out. At this laundry input port hb, a cover body 93 is provided to be opened and closed. [0019] There is a gap between the outer peripheral surface of the washing tub 10 and the inner peripheral surface of the outer tub 30. A tank cover C is provided so as to prevent the laundry R from entering the gap, and covers the gap from above. In addition, the washing machine 100 is provided with a water supply pipe H2 and an electromagnetic water supply valve V2, and also includes a pressure-sensing water level sensor S and the like. [0020] For example, when performing washing or washing, the solenoid water supply valve V2 is opened by the instruction of the control unit 50, and the washing water is supplied to the outer tank 30 through the water supply pipe H2. However, if it is detected that the system has reached a specific water level based on the detection value of the water level sensor S, the electromagnetic water supply valve V2 is closed by the control unit 50 and the water supply system is stopped. When dehydration is performed, the drain valve V1 is opened by the control unit 50, and the washing water in the outer tub 30 is discharged through the drain pipe H1. [0021] FIG. 2 is a longitudinal sectional view of a washing tub 10 and the like provided in the washing machine 100 according to the embodiment. In addition, in FIG. 2, the illustration of the dehydration hole h1 (refer FIG. 1) is abbreviate | omitted.底板 The bottom plate 12 shown in FIG. 2 is a dish-like member that closes the lower portion of the carcass plate 11 and is fixed to the lower end of the carcass plate 11. The bottom plate 12 includes a bottom portion 12 a constituting the bottom surface of the washing tub 10, and a side portion 12 b extending from the outer peripheral edge of the bottom portion 12 a toward the upper side and constituting a part of the side surface of the laundry tub 10. In addition, at the bottom portion 12a, a plurality of holes hc communicating with the outer groove 30 side are provided. [0022] The stirring blade 20 is a slightly disc-shaped member covering the bottom plate 12. The stirring blade 20 is formed such that the vicinity of the center in the diameter direction is raised toward the upper side, and the vicinity of the peripheral edge is bent upward and downward in the circumferential direction like a wave. In addition to the hole hd, the stirring blade 20 is provided with a plurality of circular recessed portions 21 and protruding portions 22 extending in the diameter direction. [0023] The circulation flow path member 70 provided on the inner peripheral surface of the carcass plate 11 is a member that guides the washing water that is pushed and flowed along with the rotation of the stirring blade 20 to the top and spits out as described above. . The circulation flow path member 70 has a long and thin plate shape in the longitudinal direction, and is bent toward the side opposite to the inner peripheral surface of the carcass plate 11 when viewed in a cross section. [0024] Although not shown in the inside of the circulation flow path member 70, a pair of ribs extending in the longitudinal direction are provided near both ends in the circumferential direction of the circulation flow path member 70. In addition, when the circulation flow path member 70 is fixed to the carcass plate 11 by screwing, the aforementioned ribs are brought into contact with the carcass plate 11 and bent, thereby becoming closely adhered to the carcass plate 11. Thereby, the vicinity of both ends of the circulation flow path member 70 in the circumferential direction can be closely adhered to the inner peripheral surface of the carcass plate 11. [0025] In addition, the lower end and the upper end of the circulation flow path member 70 are not tightly attached to the ground of the carcass plate 11 and are opened. In addition, it is a gap (hereinafter, referred to as "circulation flow path P", refer to FIG. 1) between the inside of the circulation flow path member 70 and the inner peripheral surface of the carcass plate 11, and is caused by rotation of the stirring blade 20 Raise the washing water upwards. That is, the washing water is pushed up from the bottom of the washing tub 10 to the upper part via the circulation flow path P, and then the washing water returns to the inside of the washing tub 10 through the discharge port he. In the present embodiment, a pair of circulation flow path members 70 are provided facing each other with the central axis O of the washing tub 10 as a reference (see FIG. 7A). [0026] Further, on the inner peripheral surface of the carcass plate 11, other types of circulation flow path members 80 are provided at intervals of 90 ° in the circumferential direction with respect to the circulation flow path member 70. This circulation flow path member 80 will be described using FIG. 3A. [0027] FIG. 3A is a longitudinal sectional view of a washing tub 10 and the like provided in the washing machine 100 according to the embodiment. In addition, FIG. 3A shows a longitudinal cross-sectional view of the circulation channel member 80 viewed from the front side of the washing tub 10 with the stirring blade 20 removed. As shown in FIG. 3A, the circulation flow path member 80 includes a base portion 81 and a filament collection portion 82. The base portion 81 is a plate-shaped member in which the vicinity of the upper end and the vicinity of both ends in the circumferential direction are closely adhered to the inner peripheral surface of the carcass plate 11. Although not shown, the base portion 81 is provided with an opening having a shape corresponding to the filament collection portion 82. In addition, near the lower end of the base portion 81, an inlet hf is provided for introducing washing water that is pushed and flowed by the rotation of the stirring blade 20. [0028] The shred collection unit 82 is a detachable type member for collecting shreds and the like, and is installed at the opening (not shown) of the base 81 described above. A plurality of holes hg are provided in the filament collection part 82, and a lint filter (not shown) is attached to the area of these holes hg. A discharge port hi is provided on the upper side of the plurality of holes hg to discharge the washing water. [0029] The washing water flowing in through the inlet hf is pushed up through a gap between the circulation flow path member 80 and the carcass plate 11 (hereinafter, referred to as "circulation flow path Q", not shown). In the process in which the washing water flows in the circulation flow path Q described above, the shreds collection unit 82 collects the shreds and the like, and further, the washing water returns to the washing tub 10 through the discharge port hi. . [0030] In addition, instead of providing the filament waste collection portion 82 at the aforementioned discharge outlet hi, a slit-shaped discharge outlet may be provided near the upper end of the base portion 81. In this embodiment, a pair of circulation flow path members 80 and 80 are provided facing each other with the central axis O of the washing tub 10 as a reference (see FIG. 7A). [0031] FIG. 3B is an enlarged view of a part of a range of a dotted line J shown in FIG. 3A. As shown in FIG. 3B, the washing tub 10 is provided near the edge 11b (end edge) of the peripheral wall of the washing tub 10, and has a convex portion 11a protruding toward the inside in the diameter direction. In addition, a convex portion 11 a is formed to cover the entire circumference of the peripheral wall of the washing tub 10, and a balance ring 60 is provided above the convex portion 11 a. [0032] If the installation of the balance ring 60 is further described in detail, in the state where the balance ring 60 is placed on the convex portion 11a, the vicinity of the edge 11b of the peripheral wall of the washing tub 10 is directed inward in the diameter direction. Make a bend. By such a curling operation, the vicinity of the aforementioned edge 11 b is brought into close contact with the upper surface of the rib 61 provided on the outer peripheral wall of the balance ring 60.凸 In addition, the convex portion 11a also has a function of suppressing the deformation of the washing tub 10 toward the outside in the diameter direction due to centrifugal force during dehydration and ensuring its strength during dehydration. [0033] As shown in FIG. 3B, the convex portion 11a is provided with the first inclined surface K1. The first inclined surface K1 is based on the axis 11 of the washing tub 10 and closer to the edge 11b of the peripheral wall (that is, if the height is higher), and the central axis O of the washing tub 10 (refer to FIG. 3A). The distance between the diameters will become shorter in a manner that makes it tilt. The first inclined surface K1 is an inclined surface for guiding the washing water pushed upward by the circulation flow path P to the inclined direction (to make the washing water advance toward the inside in the diameter direction as the washing water rises). [0034] The discharge side of the circulation flow path member 70 extends toward the axial direction of the washing tub 10 (in FIG. 3B, it is a vertical direction). Therefore, for example, compared with the structure which bends the vicinity of the discharge opening he of the circulation flow path member 70 toward the inside in the diameter direction (see the comparative example of FIG. 6B), it is possible to suppress a decrease in the circulation flow rate of the washing water. 3B, the front end 70a on the discharge side of the circulation flow path member 70 extends to the vicinity of the convex portion 11a of the washing tub 10 (shown in FIG. 3B). In the example, it is slightly lower than the front end of the convex portion 11a). This makes it possible to suppress a decrease in the circulating flow rate of the washing water, and to guide the washing water in a direction parallel to the first inclined surface K1 of the convex portion 11a. [0036] In addition, if the front end 70a on the discharge side of the circulation flow path member 70 is placed at a lower distance from the convex portion 11a by a certain distance or more, the washing water flows from the circulation before reaching the convex portion 11a. The possibility of the road member 70 flowing down becomes high. On the other hand, if the front end 70a on the discharge side of the circulation flow path member 70 is positioned at a distance higher than a certain distance from the convex portion 11a, the balance ring 60 and the front end 70a of the circulation flow path member 70 The distance system will become too short, and the exposure resistance will increase, which will cause the circulation flow of the washing water to decrease. Therefore, as described above, it is preferable that the front end 70a on the discharge side of the circulation flow path member 70 is located near the convex portion 11a. [0037] The balance ring 60 is attached to the lower portion of the inner peripheral surface thereof and includes a second inclined surface K2 near the convex portion 11a. The second inclined surface K2 is an inclined surface for guiding the washing water flowing out in an oblique direction along the first inclined surface K1 of the convex portion 11a, and further guiding the washing water in a substantially the same direction. This second inclined surface K2 is substantially the same plane as the first inclined surface K1 of the convex portion 11a, and is located further inward than the convex portion 11a in the diameter direction. In addition, the distance L1 between the second inclined surface K2 and the front end 70a of the circulation flow path member 70 is suitable so as not to hinder the flow of the washing water pushed up through the circulation flow path P. set up. 3B, the second inclined surface K2 is viewed in a longitudinal section (a longitudinal section at a plane containing the central axis O of the washing tub 10, see FIG. 3A). ) And exists on the extension line of the discharge side of the circulation flow path member 70. As a result, the washing water pushed up at a specific flow rate is discharged along the second inclined surface K2. [0039] Furthermore, the balance ring 60 is located on the inner side in the diameter direction than the second inclined surface K2, and is provided with a diffusion surface K3 that allows washing water to collide with itself and diffuse. In the example shown in FIG. 3B, the diffusion surface K3 is a plane (ie, a horizontal plane) perpendicular to the central axis O of the washing tub 10. As a result, the washing water flowing out along the first inclined surface K1 and the second inclined surface K2 collides with the diffusion surface K3, and the washing water can be spread over a wide range in the washing tub 10. [0040] FIG. 4 is a perspective view showing the inner side of the stirring wing 20 provided in the washing machine 100. As shown in FIG. 4, the stirring blade 20 is attached to the inside (lower side) of the stirring blade 20 and includes a plurality of inner blades extending radially from the central axis O toward the diameter direction. The inner fan blades 23 are arranged at equal angular intervals in the circumferential direction. [0041] For a more detailed description, inside the two areas that are raised above the stirring wing 20 (in FIG. 4 shown on the inside of the stirring wing 20, it is the bottom), The system is formed with inner fan leaf groups 23A and 23A. Each of the inner fan blade groups 23A is composed of five inner fan blades, and is arranged in an angular range of about 90 degrees in the circumferential direction. The inner fan group 23A is provided with a function of introducing washing water for circulation and a function of suppressing flexure and deformation of the stirring blade 20. [0042] Between the inner fan leaf groups 23A and 23A, other inner fan leaf groups 23B and 23B are provided. Here, the fan blade groups 23B and 23B are formed in the two recessed areas below the stirring blade 20 (in FIG. 4 shown on the inside of the stirring blade 20, it is upward). . The inner fan blade group 23B is composed of three inner fan blades 23 and has a function of suppressing the bending deformation of the stirring blade 20. [0043] Around the center of the inside of the stirring blade 20, three ring ribs 24 are formed, which are formed concentrically with the central axis O. These ring ribs 24 have a function of reinforcing the inner fan blade groups 23A, 23A, 23B, and 23B. [0044] Furthermore, inside the stirring blade 20, the outer peripheral side ribs 25 and the inner peripheral side ribs 26, 27 are extended in the circumferential direction, and are formed at a predetermined interval in the radial direction. The outer peripheral side ribs 25 and the inner peripheral side ribs 26 and 27 are respectively curved with a curvature that is slightly the same as the curvature of the stirring blade 20. [0045] The outer peripheral side rib 25 is a peripheral rib located on the outer peripheral side of the stirring blade 20. The outer side ribs 25 extend from the inner fan blade 23 at one end to the inner fan blade 23 at the other end in the circumferential direction of the inner fan blade group 23A, and are integrally formed with these inner fan blades 23 . [0046] The inner peripheral side ribs 26 and 27 are peripheral ribs located on the inner peripheral side rather than the outer peripheral side rib 25. The inner peripheral side ribs 26 and 27 are integrally formed with three inner fan blades 23 among the five inner fan blades 23 of the inner fan blade group 23A. [0047] FIG. 5 is a longitudinal sectional view showing a positional relationship between the inlet hj of the circulation flow path P of the washing machine 100 and the outer peripheral side ribs 25 and the inner peripheral side ribs 26 and 27. In addition, FIG. 5 is a longitudinal sectional view showing the central fan blade 23 included in the five fan blades 23 included in the fan blade group 23A (refer to FIG. 4) from the front. . [0048] Below the circulation flow path member 70 (near the bottom of the washing tub 10), a flow inlet hj that guides washing water to the circulation flow path P is provided. In addition, the space between the bottom of the inside of the washing tub 10 and the fan blades 23 inside the stirring blade 20 becomes the pump chamber M. The washing water that is pushed to the outside in the diameter direction through the pump chamber M is pumped upwards through the inflow port hj and the circulation flow path P. [0049] The outer peripheral portion of the stirring blade 20 is formed with a lower portion 28 extending downward toward the inflow port hj. A specific gap hk is provided between the vertical lower portion 28 and the circulation flow path member 70. The size of the gap hk is set to a distance such that the stirring blade 20 does not contact the circulation flow path member 70. [0050] In a state where the laundry R (refer to FIG. 1) is put into the washing machine 100 thus constituted, if the power switch (not shown) is turned ON, and the start key (not shown) is turned on When pressed further, each device is controlled by the control unit 50 (refer to FIG. 1). That is, the electromagnetic water supply valve V2 (refer to FIG. 1) is controlled and is always supplied with water to a specific water level, and moves to a laundry project. In the washing process, the driving device 40 (refer to FIG. 1), for example, the stirring blade 20 rotates in the order of right rotation, stop, left rotation, and stop. As a result, the laundry R system is stirred together with the washing water, and the laundry R system is washed. [0051] <Actions and Effects> FIG. 6A is a vertical cross-sectional view showing the flow of washing water through the circulation flow path P in the washing machine 100 according to the embodiment. In addition, the size of the blank arrow represents the magnitude of the flow rate of the washing water flowing in the circulation flow path P (the same is true for FIG. 6B). The washing water rising through the circulation flow path P is tied to the discharge port he, and is guided to the inclined direction (becomes the first inclined surface K1 of the convex portion 11a and the second inclined surface K2 of the balance ring 60). Make the washing water move in the direction of the inside of the diameter direction as it rises). Thereafter, due to the collision between the washing water and the diffusion surface K3 of the balance ring 60, the washing water is advanced toward the inside in the diameter direction. In a plan view, the washing water is scattered in a wide range within the washing tub 10. [0052] As described above, the discharge side of the circulation flow path member 70 extends in the axial direction up to the vicinity of the convex portion 11a. That is, at the discharge side of the circulation flow path member 70, the flange 71A (refer to FIG. 6B) is not provided as in the comparative example described below. Therefore, since the circulation of the washing water due to the circulation flow path member 70 is hardly hindered (the flow rate is reduced), the rotation speed of the stirring blade 20 (see FIG. 5) is not excessively increased, and Can ensure sufficient circulation flow. [0053] FIG. 6B is a longitudinal cross-sectional view showing the flow of washing water through the circulation flow path P in the washing machine of the comparative example.比较 The comparative example shown in FIG. 6B is different from the present embodiment (see FIG. 6A) in that a flange 71A is provided near the outlet hm of the circulation flow path member 70A. The flange 71A is a portion where the vicinity of the front end on the discharge side of the circulation flow path member 70A is turned toward the inside in the diameter direction and is bent. In the comparative example, the second inclined surface K2 (see FIG. 6A) is not provided under the gimbal ring 60A. This point is different from this embodiment. [0054] In the configuration shown in FIG. 6B, the washing water that is pushed upward through the circulation flow path P is directed inward in the diameter direction through the gap between the flange 71A and the balance ring 60A. Here, the gap between the flange 71A and the balance ring 60A is narrowed in the longitudinal direction, and the flow path resistance is large. Therefore, the possibility of reducing the flow of laundry water is Is high. [0055] That is, if the height of the rim 71A is lowered, the possibility that the washing water enters the gap between the rim 71A and the balance ring 60A becomes higher, and the laundry R will be connected to the rim 71A. Collision makes it vulnerable to injury. [0056] In contrast, in the present embodiment shown in FIG. 6A, the discharge side of the circulation flow path member 70 extends toward the axial direction. Therefore, near the front end of the circulation flow path member 70, the flow of washing water The road system was opened. Therefore, there is almost no case where the flow of the washing water is hindered by the circulation flow path member 70. [0057] For example, suppose that the distance L1 (the distance between the front end 70a of the circulation flow path member 70 and the second inclined surface K2) shown in FIG. 3B is the distance L2 (锷The distance between the edge 71A and the balance ring 60A is the same, and the rotation speed of the stirring blade 20 (see FIG. 2) is also the same. Even in this case, the same is true. The circulation flow rate of the washing water in this embodiment is larger than that in the comparative example. This is because, as described above, the flow path of the washing water is opened near the front end 70 a (refer to FIG. 3B) of the circulation flow path member 70. [0058] In addition, along the first inclined surface K1 of the convex portion 11a and the second inclined surface K2 of the balance ring 60, the washing water system is forced to flow, and further collides with the diffusion surface K3 of the balance ring 60. . Thereby, the washing water is scattered in a wide range in the washing tub 10 in a plan view. [0059] In addition, this embodiment is not a complicated structure like the aforementioned Patent Document 1, but a simple structure, and a shape of the laundry tank 10, the circulation flow path member 70, and the balance ring 60. To guide the washing water to a specific direction. Furthermore, it is not necessary to additionally provide a rectifying rib (not shown) on the inner peripheral surface of the washing tub 10 to guide washing water to a specific direction. This makes it possible to reduce programs and costs required for manufacturing the washing machine 100. In addition, it is possible to prevent the filaments and the like from entering the gaps in the circulation flow path member 70. [0060] FIG. 7A is a plan view showing a range in which the washing water is scattered in the washing tub 10 of the washing machine 100 according to the embodiment. Note that the illustration of the balance ring 60 is omitted in FIG. 7A (the same is true for FIG. 7B). (2) As described above, in this embodiment, the flow rate of the washing water is hardly reduced, and the washing water is dispersed into the washing tub 10 through the discharge port he. As a result, the distance between the washing water and the scattered water is longer than that of the comparative example (refer to FIG. 6B). Therefore, in a plan view, the washing water covers almost the entire area of the washing tub 10 (area U in the oblique line). And was scattered. As a result, the washing water is scattered from the laundry R (refer to FIG. 1) like a bath. Therefore, uneven washing conditions such as during washing are reduced, and washing performance can be improved. [0061] FIG. 7B is a plan view showing a range in which the washing water in the washing tub 10A of the washing machine of the comparative example in FIG. 6B is scattered.构成 In the configuration of the comparative example (refer to FIG. 6B), as described above, the flow rate of the washing water is reduced at the gap between the rim 102 and the balance ring 60A. As a result, as shown in FIG. 7B, in a plan view, there is an area where there is no scattered water and no washing water. Specifically, in the linear gaps (gap between the regions U1 and U2 of the oblique line portions) connecting the circulation flow path members 80 and 80, there is a high possibility that the water will not be scattered and there will be washing water. [0062] On the other hand, according to this embodiment, as described above, the washing water discharged from the discharge port he (see FIG. 7A) is scattered into almost the entire area of the washing tub 10 in plan view. . Therefore, the washing water can be appropriately circulated through the circulation flow path P (see FIG. 6A). [0063] ≪Modifications≫ Although the washing machine 100 of the present invention has been described based on the embodiment, the present invention is not limited to these descriptions, and various changes can be made. For example, in the embodiment, the balance ring 60 has been described as having a structure having a second inclined surface K2 (see FIG. 3B) and a diffusion surface K3 (see FIG. 3B), but the system is not limited to this. this. That is, the balance ring 60 may have a configuration in which one or both of the second inclined surface K2 and the diffusion surface K3 are not provided. Even in such a configuration, a simple configuration can appropriately circulate the washing water through the circulation flow path P (see FIG. 3B). Instead of the balance ring 60, for example, a ring-shaped frame may be provided. [0064] In the embodiment, the first inclined surface K1, the second inclined surface K2, and the diffusion surface K3 have been described as having a linear configuration when viewed in a longitudinal section (see FIG. 3B). However, the system is not limited to this. That is, at least one of the first inclined surface K1, the second inclined surface K2, and the diffusion surface K3 may have a curved shape when viewed in a longitudinal section. [0065] In the embodiment, the configuration in which the second inclined surface K2 exists on the extension line of the circulation flow path member 70 on the discharge side as viewed in a longitudinal section has been described (refer to FIG. 3B). However, the system is not limited to this. For example, the intersection point between the extension line on the discharge side of the circulation flow path member 70 and the gimbal ring 60 as viewed in the longitudinal section may be located further inward than the second inclined surface K2 in the diameter direction. [0066] In the foregoing embodiment, the configuration has been described with two circulation flow path members 70, 70 and other types of circulation flow path members 80, 80 (refer to FIG. 7A). However, the number of these components may be changed as appropriate. In the embodiment, the washing machine 100 that performs washing, washing, and dehydration has been described, but the system is not limited to this. For example, this embodiment can also be applied to a washer-dryer that performs drying in addition to washing, washing, and dehydration. [0067] The embodiments are described in detail for easy understanding of the present invention, and the present invention is not limited to the constituents including all of the descriptions. In addition, it is possible to add, delete, and replace other configurations with respect to a part of the configuration of the embodiment. In addition, the aforementioned institutions or structures are representatives who are considered to be needed in the description, and not necessarily all the institutions or structures on the product.
