以下，針對本實施形態中的洗衣機之加熱器單元32進行說明。Hereinafter, the
如圖1所示，在水槽13背面側的外底部，且能夠卸除背板17來維護的位置上，固定有加熱器單元32。As shown in Fig. 1, a
如圖2所示，加熱器單元32是由下列零件所構成：加熱器收容容器37，長邊方向之兩端有開口的大致長方體形狀；加熱器38，從加熱器收容容器37的第1開口***；板金構件36，從加熱器收容容器37的第2開口***，並覆蓋加熱器38；及蓋體51，覆蓋可供板金構件36***的第2開口。As shown in FIG. 2, the
以下，針對各零件進行說明。 [A.加熱器收容容器37]Hereinafter, each part will be described. [A. Heater storage container 37]
加熱器收容容器37是由耐熱性樹脂所形成，形成為長邊方向之兩端有開口的大致長方體形狀。在加熱器收容容器37之長邊方向的開口中，第1開口是***加熱器38的加熱器***用開口部37b，第2開口是***板金構件36並藉由蓋體51加以覆蓋的板金構件***用開口部37c。The
在加熱器收容容器37上表面的加熱器***用開口部37b附近，形成有與水槽13底部之第2排水口33b連通的筒狀之流出路徑部37g。In the vicinity of the
在與具有流出路徑部37g之面鄰接的側面之板金構件***用開口部37c附近，形成有與排水旋塞閥單元34連通的排水旋塞閥連接用開口部37a。排水旋塞閥單元34與加熱器收容容器37是藉由螺絲鎖結(圖未示)等而安裝成能夠裝卸。A drain
如圖2所示，排水旋塞閥單元34在流入口34a與水槽13底部之第1排水口33a連通的位置，藉由焊接凸座45加以焊接固定。水槽13與加熱器收容容器37是透過排水旋塞閥單元34而連通連接。如圖2、圖3、圖4B所示，排水旋塞閥單元34具有排水路徑側開口部34c。排水路徑側開口部34c與排水路徑41(參照圖1)連接連通。藉由開啟排水旋塞閥單元34的排水閥(圖未示)，水槽13及加熱器收容容器37內的洗衣水就會通過排水路徑41而被排水至洗衣機本體11的外部。As shown in FIG. 2, the
再者，在本實施形態中，雖然水槽13與排水旋塞閥單元34是焊接固定的，但本發明並非限定於此，亦可藉由螺絲鎖結等來安裝成能夠裝卸。 [B.板金構件36]Furthermore, in this embodiment, although the
如圖2所示，圍繞加熱器38的板金構件36形成為長邊方向之兩端有開口的大致長方體形狀。板金構件36是從板金構件***用開口部37c朝向前方***加熱器收容容器37內。As shown in FIG. 2, the
由於從加熱器38所產生的輻射熱會傳導過板金構件36而擴散，所以能夠降低熱能集中於加熱器收容容器37的一部分而熔融產生破洞的風險。Since the radiant heat generated from the
板金構件36是由2片板金零件所構成。如圖2、圖6所示，板金構件36的一端是沿長邊方向的點焊部42被點焊。如圖6、圖7所示，板金構件36的另一端具有未被焊接且具備一定間隙的間隔部36a。因此，板金構件36形成為大致U字形狀。板金構件36是藉由彎曲加工而形成有向內凹陷的支撐片40。此支撐片40會將收納於加熱器收容容器37內的加熱器38固定成不會移動。The
使用圖5、圖6、圖7來說明板金構件36與加熱器收容容器37的固定方法。The fixing method of the
如圖5所示，在加熱器收容容器37的內壁延伸形成有帶狀肋37d，該帶狀肋37d會對應於板金構件36***加熱器收容容器37內的狀態下的間隔部36a之位置。在將板金構件36從板金構件***用開口部37c朝向前方***加熱器收容容器37內時，帶狀肋37d會位於間隔部36a。As shown in FIG. 5, a strip-shaped
如圖6、圖7所示，在板金構件36***加熱器收容容器37內的狀態下，在與板金構件36抵接之位置的帶狀肋37d之寬度尺寸W形成為從後側朝向前側變寬。As shown in Figures 6 and 7, in the state where the
圖7之帶狀肋37d的板金構件***用開口部37c側(後側)端之寬度尺寸W1是形成為比板金構件36收納於加熱器收容容器37內的狀態下的間隙部36a之間隔寬度更狹窄。圖7之帶狀肋37d的加熱器***用開口部37b側(前側)端之寬度尺寸W2是形成為比板金構件36收納於加熱器收容容器37內部的狀態下的間隙部36a之間隔寬度更寬。又，如圖8所示，隨著從板金構件***用開口部37c側(後側)朝向加熱器***用開口部37b側(前側)靠近，加熱器收容容器37的內壁下表面39a會往上方，且內壁上表面39b會往下方逐漸傾斜。因此，隨著板金構件36從板金構件***用開口部37c側(後側)朝向加熱器***用開口部37b側(前側)***，間隔部36a的間隔寬度會變狹窄。The width dimension W1 at the end of the sheet metal
藉由此構成，板金構件36在加熱器收容容器37內從板金構件***用開口部37c側(後側)朝向加熱器***用開口部37b側(前側)***後，從***途中開始，帶狀肋37d的寬度W就會變得比板金構件36之間隔部36a的間隔寬度更寬。因此，藉由壓入板金構件36以將其推入加熱器收容容器37內，板金構件36的間隔部36a的端部會嵌入帶狀肋37d。像這樣進行，就能夠將板金構件36支撐固定於加熱器收容容器37內，並在洗衣兼脫水槽15的脫水旋轉時，能夠防止板金構件36晃動。With this configuration, the
在本實施形態中，雖然板金構件36是藉由將2片板金加以點焊所構成，但例如成形1片板金來構成亦可。 [C.加熱器38]In the present embodiment, although the
使用圖2，針對加熱器38進行說明。The
加熱器38是從加熱器收容容器37的加熱器***用開口部37b***。The
加熱器38是藉由加熱部38a、端子部38b及連接部38c所構成。The
加熱部38a位於加熱器收容容器37內部，會產生用以將加熱器收容容器37內之洗衣水加熱的熱能。又，如圖2所示，加熱部38a在同一平面上被多次彎折。藉由此構成，由於加熱部38a的表面積會變大，因此能夠有效率地將洗衣水加熱。The
端子部38b與加熱部38a電性連接。又，端子部38b與位於加熱器收容容器37之外部的外部電源(圖未示)、及控制裝置(圖未示)電性連接。來自外部電源的電力會透過端子部38b朝加熱部38a供給。The
連接部38c介於加熱部38a與端子部38b之間。在連接部38c設置有可撓性構件38d，該可撓性構件38d為對應於加熱器收容容器37之加熱器***用開口部37b的大小。在圖8中，在加熱部38a***加熱器***用開口部37b內的狀態下，藉由鎖緊螺帽43，便能夠將加熱器38固定於加熱器收容容器37內。亦即，藉由鎖緊螺帽43，就會對螺栓44及焊接於螺栓44的壓接板47施加朝向前方向的力量，使得可撓性構件38d朝前後方向被壓縮而朝周圍方向膨脹，因此能夠密封加熱器***用開口部37b。藉由此構成，能夠防止加熱器收容容器37內的洗衣水從加熱器***用開口部37b漏水。可撓性構件38d是以能夠彈性變形之例如橡膠等的襯墊所形成。The connecting
又，如圖2所示，在連接部38c配設有溫度檢測部56，該溫度檢測部56會測量加熱器收容容器37內的水溫。溫度檢測部56是由熱敏電阻等所構成。 [D.蓋體51]In addition, as shown in FIG. 2, a
如圖8、圖9所示，蓋體51是藉由螺絲鎖結(圖未示)而可裝卸地覆蓋著加熱器收容容器37的板金構件***用開口部37c。As shown in FIGS. 8 and 9, the
為了要卸除蓋體51來確認加熱器收容容器37內，並進行加熱器單元32的維護，藉由蓋體51所覆蓋的板金構件***用開口部37c是設置於洗衣機本體11的具有背面開口部11a之背面側。In order to remove the
藉由蓋體51所覆蓋的板金構件***用開口部37c是安裝於面對***加熱器收容容器37內的加熱器38的位置。藉由作成此構成，從加熱器收容容器37卸除蓋體51，就能夠輕易地看到加熱器38的狀態。The
在蓋體51形成有傾斜肋51a，該傾斜肋51a是一種會將***加熱器收容容器37內的板金構件36朝加熱器收容容器37的內壁面側推入的凸狀肋。傾斜肋51a具有與收納於加熱器收容容器37的板金構件36相對向的傾斜面，傾斜面是從圖8之以箭頭表示的「前」側朝向「後」側來靠近加熱器收容容器37的內壁面而傾斜。藉由此構成，***加熱器收容容器37內的板金構件36的板金構件***用開口部37c側的端部，會藉由傾斜肋51a而朝向內壁下表面39a及內壁上表面39b擴展。***加熱器收容容器37內的板金構件36的板金構件***用開口部37c側(後側)端部，會藉由傾斜肋51a而朝向內壁下表面39a及內壁上表面39b擴展。The
又，在加熱器收容容器37安裝於水槽13底部的狀態下，在加熱器收容容器37的內壁下表面39a與內壁上表面39b，延伸形成有支撐板金構件36的肋部37e(參照圖6)。藉由肋部37e，來抑制由加熱器38所加熱之板金構件36的熱直接傳達至內壁下表面39a、及內壁上表面39b。In the state where the
藉由此構成，在將板金構件36***加熱器收容容器37內的狀態下，藉由蓋體51覆蓋板金構件***用開口部37c，板金構件36就會藉由傾斜肋51a與肋部37e被支撐固定。因此，會抑制板金構件36在加熱器收容容器37內揺動。With this configuration, when the
像這樣進行來構成加熱器單元32。 [1-2.洗衣機的運轉動作]In this way, the
接著，說明本實施形態中的洗衣機的運轉動作。Next, the operation of the washing machine in this embodiment will be described.
使用者打開門體27，將衣物從洗滌物投入取出口26投入洗衣兼脫水槽15內，然後關閉門體27，接著對操作顯示部29進行操作，開始溫水洗衣行程。The user opens the
當洗衣步驟開始後，供水閥30會開啟，水會從注水箱31注入到水槽13內。被注入的水會從水槽13底部的第1排水口33a、及第2排水口33b朝加熱器收容容器37內流入。When the washing step starts, the
在此，在溫水洗衣行程中，在使用了藉由加熱器38所產生之加熱水的洗衣步驟結束後，會執行沖洗、脫水的步驟。Here, in the warm water washing process, after the washing step using the heated water generated by the
在溫水洗衣行程中，藉由對水槽13的注水而使水槽13內的水達到預定的水位後，加熱器單元32的加熱器38便會開啟。控制裝置會因應水槽內之洗衣水的水溫，控制加熱器38開啟/關閉，來控制洗衣水的溫度。關於水槽內的水溫檢測方法，將在[1-5.水槽內的水溫檢測方法]說明。In the warm water washing process, after the water in the
在水槽13內的水溫達到預定溫度M1(例如55℃)時，會關閉加熱器38。又，在水槽13內的測量水溫下降至預定溫度M2以下(例如53℃以下)時，會開啟加熱器38。藉由此方法，能夠將水槽13內的洗衣水調節至預定的水溫。When the water temperature in the
再者，預定溫度M1、M2亦可依各運轉行程(例如除菌行程或泥污行程)來設定。令預定溫度M1、M2依據運轉行程而變更，藉此就能夠將洗衣水調節至適合各個運轉行程之目的之水溫。Furthermore, the predetermined temperatures M1 and M2 can also be set according to each operation stroke (for example, a sterilization stroke or a muddy stroke). The predetermined temperature M1 and M2 are changed according to the operation schedule, so that the washing water can be adjusted to the water temperature suitable for the purpose of each operation schedule.
又，溫水洗衣結束後，直到水槽13內的水溫變成預定溫度以下(例如50℃以下)為止，亦可重複在洗衣兼脫水槽15內追加水並藉由脈動器18來攪拌的動作。當水槽13內的水溫變成50℃以下後，排水旋塞閥單元34的排水閥會開啟，洗衣水會被排水至洗衣機本體11的外部。在水槽13內的水溫變成預定溫度以上(例如50℃以上)，且水槽13內的水位達到極限時，會以預定時間實施臨時排水。In addition, after the warm water washing is completed, until the water temperature in the
藉由此構成，即便是在將排水朝路面隨地排放的環境下，由於能夠在已降低水溫的狀態下來對洗衣水進行排水，所以安全性會提升。With this configuration, even in an environment where the water is discharged on the road surface, since the washing water can be drained in a state where the water temperature has been lowered, the safety is improved.
另一方面，若由於衣物的線屑等，而堵塞加熱器收容容器37的流出路徑37g的話，恐有加熱器收容容器37與水槽13的水流受到阻礙的疑慮。加熱器收容容器37與水槽13的水流受到阻礙的話，可以設想會有一種儘管水槽內的水溫在預定溫度M1以下，但加熱器單元32內卻成為過熱狀態的情況。這種情況下，藉由控制成在檢測加熱器收容容器37內之水溫的溫度檢測部56之測量水溫達到加熱器過熱設定溫度(例如95℃)時會關閉加熱器38，就能夠防止加熱器單元32內的過熱，而能夠抑制水垢的產生或加熱器收容容器37的劣化。 [1-3.加熱器單元內的洗衣水之流動]On the other hand, if the
圖10是顯示本實施形態中的洗衣機之加熱器單元內的洗衣水之流動的局部截面立體圖。Fig. 10 is a partial cross-sectional perspective view showing the flow of washing water in the heater unit of the washing machine in this embodiment.
使用圖10，來說明在溫水洗衣行程中，加熱器38被開啟時的加熱器單元32內的洗衣水之流動。Using FIG. 10, the flow of washing water in the
在加熱器收容容器37上表面的加熱部38a根部側，形成有與水槽13內底部連通的流出路徑部37g，在加熱器收容容器37側面的加熱部38a前端部的側方之側，連結有與水槽13內底部連通的排水旋塞閥單元34。On the root side of the
在加熱器收容容器37內被加熱而使得水溫變高的洗衣水，會在加熱器收容容器37內上升。The washing water heated in the
在此，由於起始自加熱器38的距離是流出路徑部37g比排水旋塞閥連接用開口部37a更近，所以在加熱器38的電源開啟的狀態下，加熱器收容容器37內的水溫會是流出路徑部37g變得比排水旋塞閥連接用開口部37a更高。因此，在加熱器收容容器37內上升的洗衣水如圖10的箭頭D所示，通過流出路徑部37g而被放出至水槽13。Here, since the starting distance from the
為了填補從加熱器收容容器37朝水槽13被放出之高溫的洗衣水，水槽13內之低溫且比重較重的洗衣水會如圖10的箭頭C所示，從流入口34a通過比排水旋塞閥單元34的排水旋塞閥更上游側的排水旋塞閥前路徑34b，而流入加熱器收容容器37內底部。流入加熱器收容容器37內的洗衣水會一邊從加熱器38之加熱部38a的前端附近朝向根部附近流動，一邊有效利用加熱器38的輻射熱來加熱，因此能夠有效率地將洗衣水加熱。In order to make up for the high-temperature washing water discharged from the
像這樣，藉由在與加熱器38間之距離不同的位置設置將水槽13與加熱器收容容器37連結的2條路徑(流入口34a、流出路徑部37g)，就能夠利用各別之路徑內的洗衣水之水溫的差異，藉由自然對流來使水槽13內的洗衣水與加熱器收容容器37內的洗衣水循環。因此，能夠在不需要泵等外力的情況下減少零件數量，從而削減成本。In this way, by providing two paths (
又，由於加熱器收容容器37與水槽13相比容量較小，所以比起水槽13內的洗衣水，加熱器收容容器37內的洗衣水藉由加熱器38所實現的升溫速度更快且水溫變更高。因此，能夠有效地將流入加熱器收容容器37內之洗衣水所包含的細菌等滅菌。In addition, since the capacity of the
另外，藉由每隔一定時間就使脈動器18旋轉，會攪拌水槽13內的洗衣水，能夠使水槽13內的水溫達到均一。In addition, by rotating the
在本實施形態中，第1排水口33a、及第2排水口33b的開口面積較大者，能夠使加熱器單元32與水槽13之洗衣水的循環活躍化。然而，如果將第1排水口33a、第2排水口33b作成正圓形狀且加大開口面積的話，會導致與第1排水口33a、第2排水口33b周邊的焊接凸座45或內紋螺桿46等產生干涉，因此需要大幅改造水槽13底部。In this embodiment, the larger opening areas of the
因此，藉由如圖2所示地將第1排水口33a以大致橢圓形狀來構成，不需變更焊接凸座45、及內紋螺桿46的位置，便能夠加大第1排水口33a的開口面積。因此，也不需進行高額的模具投資，能夠以低成本有效率地循環水槽13與加熱器收容容器37內的洗衣水。Therefore, by forming the
又，如圖8所示，加熱器收容容器37底側的內壁下表面39a是從加熱器***用開口部37b朝向排水旋塞閥連接用開口部37a往下方逐漸傾斜。藉由此構成，在排水時，加熱器收容容器37內的洗衣水會朝向排水旋塞閥連接用開口部37a流動，通過排水旋塞閥單元34、排水路徑41(參照圖1)而流出至洗衣機本體11的外部。因此，能夠防止排水時之加熱器收容容器37內的洗衣水或異物滯留。 [1-4.加熱器單元的狀態確認、及維護方法]Moreover, as shown in FIG. 8, the
由於從衣物所產生之較大的線屑等之異物會附著於加熱器38，或堵塞流出路徑部37g，而恐有加熱器收容容器37內的加熱水變得無法朝水槽13流出的疑慮。又，會有在加熱器單元32的零件中產生不良狀況的情況。因此，變得有必要因應需要來進行加熱器單元32內之狀態的確認或修補。Since foreign matter such as large thread scraps generated from the clothes may adhere to the
以下，針對加熱器單元32內的狀態確認及維護方法進行說明。Hereinafter, the state confirmation and maintenance method in the
為了確認加熱器單元32的狀態，會將覆蓋洗衣機本體11後方側之背面開口部11a的背板17卸除，並從背面開口部11a將安裝於水槽13底面之加熱器收容容器37的蓋體51卸除。由於加熱器收容容器37與蓋體51是藉由螺絲鎖結所固定，所以鬆開螺絲便能夠卸除蓋體51。In order to confirm the state of the
藉由此方法，能夠從洗衣機本體11之背面開口部11a確認加熱器收容容器37內之加熱器38的狀態，並因應需要將附著於加熱器38表面的線屑等清除。因此，由於不需要對連接於加熱器38的引線連接器進行裝卸，所以變得能夠輕易地進行加熱器38的確認、及維護。With this method, the state of the
又，在想修補或更換板金構件36時，從加熱器收容容器37抽出板金構件36即可卸除，變得能夠修補、更換。In addition, when it is desired to repair or replace the
又，加熱器單元32與水槽13、及加熱器單元32與排水旋塞閥單元34，是藉由螺絲等(圖未示)所鎖結而安裝成能夠拆卸。藉由此構成，在需要將侵入加熱器單元32內的異物清除時，或是變得需要更換加熱器單元32時，能夠將洗衣機本體11橫向放倒，從洗衣機本體11的底部就能夠將加熱器單元32從水槽13與排水旋塞閥單元34卸除，變得能夠進行加熱器單元32單體的維護。又，能夠僅維護加熱器單元32的破損零件，所以能夠削減修補所需的時間或費用。 [1-5.水槽內的水溫檢測方法]In addition, the
圖11是本實施形態中的洗衣機之加熱器收容容器37內的水溫與水槽13內的水溫的圖表。FIG. 11 is a graph of the water temperature in the
加熱器38在時刻Ta0開啟的話，加熱器收容容器37內的水會藉由加熱器38被加熱。由於加熱器收容容器37與水槽相比容積較小，所以加熱器收容容器37內的水溫與水槽13內的水溫相比，一般會變成高10~40℃的狀態，但在時刻Ta1關閉加熱器38並經過預定時間後，水槽13內的水溫與加熱器收容容器37內的水溫會漸漸均一化並在時刻Ta2成為幾乎相同的水溫。When the
以下，針對使用了配設於加熱器38之溫度檢測部56的水槽13內之水溫的推測方法進行說明。Hereinafter, a method for estimating the temperature of the water in the
在溫水洗衣行程中，藉由對水槽13的注水而達到預定的水位後，加熱器單元32便會開啟。將此時的時刻設為Ta0。接著，在加熱器38開啟而經過預定時間後(將此時的時刻設為時刻Ta1)，關閉加熱器38。在關閉加熱器38後，在經過加熱器收容容器37內的水溫與水槽13內的水溫會成為大致均一的預定時間後(將此時的時刻設為時刻Ta2)，藉由溫度檢測部56來測量加熱器收容容器37的水溫，藉此便能夠推測水槽13內的水溫。In the warm water washing process, after the predetermined water level is reached by filling the
加熱器38的開啟時間(從時刻Ta0到時刻Ta1的期間)宜藉由加熱器38的輸出或、水槽13內的水量、衣物的量等來算出。例如，加熱器的輸出為1500W、水槽13內的水量為66L、衣物的量為5kg，從初期的水溫20℃加熱至預定的溫度55℃時，為130分左右。The turn-on time of the heater 38 (the period from the time Ta0 to the time Ta1) is preferably calculated from the output of the
關閉加熱器38的預定時間(從時刻Ta1到時刻Ta2的期間)宜為例如1~5分。The predetermined time for turning off the heater 38 (the period from the time Ta1 to the time Ta2) is preferably, for example, 1 to 5 minutes.
在關閉加熱器38達預定時間後，使脈動器18旋轉預定時間，藉此就會攪拌水槽13內的洗衣水，能夠促進水槽13與加熱器收容容器37之水溫差的平衡。因此，加熱器收容容器37與水槽13內的水溫差會在短時間內變小，能夠高精度地檢測水槽13內的水溫。After the
藉由此方法，能夠使用測量加熱器收容容器37內之水溫的溫度檢測部56，來進行水槽13內之洗衣水的溫度調整。因此，不需要在水槽內配設水溫檢測部，能夠以低成本提供可靠性高的洗衣機。 [2.第2實施形態]With this method, the
接著，針對本發明之第2實施形態中的洗衣機進行說明。Next, the washing machine in the second embodiment of the present invention will be described.
再者，由於本實施形態中的洗衣機的構成零件與第1實施形態中的洗衣機是相同的，所以對於相同的零件會附加相同的符號，且關於各構成零件會省略說明。 [2-1.水槽內的水溫控制方法]In addition, since the components of the washing machine in this embodiment are the same as those of the washing machine in the first embodiment, the same reference numerals are attached to the same components, and the description of each component will be omitted. [2-1. Water temperature control method in the water tank]
在此，說明在本實施形態中的洗衣機中，使用溫度檢測部56，將水槽13內的洗衣水調節至預定的目標設定水溫(例如53℃)的控制方法。Here, in the washing machine of the present embodiment, a control method for adjusting the washing water in the
本實施形態之洗衣機具備：洗衣機本體11；水槽13，被支撐於洗衣機本體11的內部，且在底部具有排水口；及排水旋塞閥單元34，與水槽13的排水口連結。又，具備：加熱器單元32，連結於排水旋塞閥單元34，並與水槽13的內底部連通；加熱器38，內藏於加熱器單元32並將洗衣水加熱；及溫度檢測部56，測量加熱器單元32內的水溫。另外，具有控制部(圖未示)，會控制加熱器38的通電，以使水槽13內的洗衣水到達預定的目的設定水溫，該控制部會在對於水槽13內的供水結束後，至少從被供水至水槽13內之水的水溫與供水量來算出並決定加熱器38的第1通電時間，而在第1通電時間的期間內，對加熱器38通電。在此，加熱器38可在第1通電時間的期間內持續通電，亦可在第1通電時間的期間內間歇通電。The washing machine of this embodiment includes a
又，控制部會在第1通電時間內，依據溫度檢測部56所測得的測量溫度來算出水槽13內的洗衣水的升溫速度Vt。另外，控制部會從升溫速度Vt與第1通電時間結束後之水槽13內的水溫，算出水槽13內的洗衣水到達目標設定水溫為止之加熱器38的第2通電時間。並且，控制部會在所算出之第2通電時間的期間內，對加熱器38通電。在此，加熱器38可在第2通電時間的期間內持續通電，亦可在第2通電時間的期間內間歇通電。In addition, the control unit calculates the temperature increase rate Vt of the washing water in the
在第2通電時間的期間內，對加熱器38持續通電後，藉由溫度檢測部56推測水槽13內的水溫，並與目標設定水溫作比較。在水溫比目標設定水溫更低時，對加熱器38通電達預定時間，然後再次依據溫度檢測部56的測量溫度來推測水槽13內的水溫。在水溫比目標設定水溫更高時，不對加熱器38通電達預定時間，然後再次依據溫度檢測部56的測量溫度來推測水槽13內的水溫。During the second energization time, after the
藉由此方法，能夠只以設置於加熱器收容容器37內的溫度檢測部56，來檢測加熱器38的過熱並且進行水槽13內之洗衣水的溫度調整。因此，能夠以低成本提供可靠性高的洗衣機。 [3.第3實施形態]With this method, only the
第1實施形態中的洗衣機構成為，加熱器收容容器37與水槽13內底面是以2條路徑連結，來循環加熱器收容容器37內的加熱過的洗衣水與水槽13內的洗衣水。然而，在第1實施形態中，有必要在水槽13設置複數個排水口。因此，第3實施形態中的洗衣機構成為，加熱器收容容器與水槽內底面是以1條路徑連結。The washing machine in the first embodiment is configured such that the
以下，使用圖12~圖16，針對第3實施形態進行說明。再者，關於洗衣機的縱向截面圖則參照圖1。Hereinafter, the third embodiment will be described using FIGS. 12 to 16. Furthermore, for the longitudinal cross-sectional view of the washing machine, refer to FIG. 1.
雖然在第1實施形態中的洗衣機的水槽13底部具有第1排水口33a與第2排水口33b，但在本實施形態中的洗衣機的水槽113底部具有排水口133。由於本實施形態中的洗衣機的其他構成與第1實施形態中的洗衣機的構成是相同的，所以省略說明。 [3-1.加熱器單元的構成]Although the washing machine in the first embodiment has a
圖12是本實施形態中的洗衣機之加熱器單元的分解立體圖。圖13是本實施形態中的洗衣機之水槽底面、排水旋塞閥單元及加熱器單元的截面圖。圖14、圖15是本實施形態中的洗衣機之加熱器單元的立體圖。Fig. 12 is an exploded perspective view of the heater unit of the washing machine in this embodiment. Fig. 13 is a cross-sectional view of the bottom surface of the sink, the drain cock unit, and the heater unit of the washing machine in this embodiment. 14 and 15 are perspective views of the heater unit of the washing machine in this embodiment.
以下，針對本實施形態中的洗衣機之加熱器單元132進行說明。Hereinafter, the
如圖13所示，在水槽113背面側之外底部的能夠卸除背板17(參照圖1)來進行維護的位置上，固定有加熱器單元132。As shown in Fig. 13, a
如圖12所示，加熱器單元132是由下列零件所構成：加熱器收容容器137，長邊方向之兩端有開口的大致長方體形狀；加熱器138，從加熱器收容容器137的一開口***；板金構件136，從加熱器收容容器137的另一開口***，並覆蓋加熱器138；及蓋體151，覆蓋可供板金構件136***的加熱器收容容器137之開口。As shown in FIG. 12, the
以下，針對各零件進行說明。再者，由於本實施形態中的加熱器138與第1實施形態之加熱器38是相同的構成，所以省略說明。 [A.加熱器收容容器137]Hereinafter, each part will be explained. In addition, since the
如圖12所示，加熱器收容容器137是由耐熱性樹脂所形成，形成為長邊方向之兩端有開口的大致長方體形狀。As shown in FIG. 12, the
在加熱器收容容器137之長邊方向側的側面之板金構件***用開口部137c附近，具有與排水旋塞閥單元134連通的排水旋塞閥連接用開口部137a。雖然在第1實施形態中的洗衣機中，在加熱器收容容器37上表面形成有與水槽13底部之第2排水口33b連通的筒狀之流出路徑部37g，但在本實施形態中的洗衣機之加熱器收容容器137中，並未形成有那種路徑。其他加熱器收容容器137的構成與第1實施形態之加熱器收容容器37的構成是相同的。In the vicinity of the
如圖13所示，排水旋塞閥單元134是以螺絲等可裝卸地安裝於水槽113底部的排水口133。如圖13所示，排水旋塞閥單元134的一部分形成為朝向加熱器收容容器137延伸的L字形狀，且水槽113與加熱器收容容器137是透過排水旋塞閥單元134連通連接。如圖13所示，在排水旋塞閥單元134設置有分隔壁146，該分隔壁146會將排水旋塞閥單元134內的從水槽113連通至加熱器收容容器137的路徑加以分離。分隔壁146是由垂直部146a、及從垂直部146a的下端朝向加熱器138延伸的水平部146b所構成，形成為截面L字形狀。藉由分隔壁146，排水旋塞閥單元134內的水路在圖13中會分離成：流入路徑135a，位於垂直部146a的左方及水平部146b的下方；及流出路徑135b，位於水平部146b的上方及垂直部146a的右方。As shown in FIG. 13, the
如圖13所示，在本實施形態中，加熱器收容容器137之內壁上表面139b的傾斜角度與內壁下表面139a的傾斜角度是以大致同一角度所形成。藉由作成此構成，如圖14、圖15所示，即便將加熱器收容容器137上下倒置，也能夠透過排水旋塞閥單元134***水槽113的底部來使用。因此，能夠就每一種洗衣機的機種，考慮振動的重心或零件的配置等來配置加熱器單元132。 [B.板金構件136]As shown in FIG. 13, in this embodiment, the inclination angle of the
如圖12所示，環繞加熱器138的板金構件136形成為長邊方向之一端有開口的大致長方體形狀。板金構件136是將1片板金構件成形為長方體形狀所構成。如圖13所示，板金構件136的長邊方向之一端具有未被焊接且具備一定間隙的間隙部136a。在板金構件136的內面，焊接有將加熱器138支撐固定的支撐片140。支撐片140會將收納於加熱器收容容器137內的加熱器138固定成不會移動。As shown in FIG. 12, the
再者，板金構件136亦可例如將2片板金以點焊等焊接來構成。In addition, the
關於板金構件136與加熱器收容容器137的固定方法，與第1實施形態是相同的。 [C.蓋體151]The method of fixing the
如圖13所示，蓋體151是藉由未圖示之螺絲等的鎖結而可裝卸地覆蓋著加熱器收容容器137的板金構件***用開口部137c。As shown in FIG. 13, the
雖然在第1實施形態中的洗衣機的蓋體51中，形成有為凸狀肋的傾斜肋51a(參照圖6)，但在本實施形態中的洗衣機的蓋體151中，並未形成有這種肋部。第2實施形態中的蓋體151的其他構成與第1實施形態中的蓋體51的構成是相同的。Although the
像這樣進行來構成加熱器單元132。 [3-2.加熱器單元內的洗衣水之流動]In this way, the
圖16是顯示本實施形態中的洗衣機之加熱器單元內的洗衣水之流動的截面圖。使用圖16，來說明在溫水洗衣行程中，加熱器138被開啟之狀態的加熱器單元132內的洗衣水之流動。Fig. 16 is a cross-sectional view showing the flow of washing water in the heater unit of the washing machine in this embodiment. Using FIG. 16, the flow of washing water in the
如圖12所示，在加熱器收容容器137的長邊方向側面，連結有與水槽113內底部連通的排水旋塞閥單元134。如圖13所示，在排水旋塞閥單元134的內部設置有分隔壁146。分隔壁146形成為將下方朝向加熱器138延伸的大致L字形狀。藉由分隔壁146，能夠防止低溫的洗衣水與高溫的洗衣水在排水旋塞閥134內混合，而有效率地循環洗衣水，該低溫的洗衣水是從水槽113朝向加熱器收容容器137流動的流入路徑135a內之低溫的洗衣水，該高溫的洗衣水是從加熱器收容容器137朝向水槽113流動的流出路徑135b內之高溫的洗衣水。As shown in FIG. 12, a
在加熱器收容容器137內充滿洗衣水的狀態下，開啟加熱器138的話，加熱器收容容器137內的洗衣水會藉由加熱器138被加熱，而在加熱器收容容器137內上升，並如圖16的箭頭B所示地從流出路徑135b排出至水槽113。When the
另一方面，為了填補從加熱器收容容器137朝水槽113被放出之高溫的洗衣水，水槽113內之低溫且比重較重的洗衣水會如圖16的箭頭A所示，通過流入路徑135a朝加熱器收容容器137內流入。由於加熱器收容容器137內之被加熱的洗衣水會移動至上方，所以水槽113內之低溫的洗衣水會變得容易從流入路徑135a流入加熱器收容容器137底部側。On the other hand, in order to make up for the high-temperature washing water discharged from the
已流入加熱器收容容器137內的洗衣水會藉由加熱器138被加熱，而在加熱器收容容器137內上升，並從流出路徑135b流出至水槽113。The washing water that has flowed into the
像這樣，將加熱器收容容器137與水槽113內底部藉由1條路徑連通，且藉由洗衣水之溫度差所造成的自然對流來使洗衣水循環，藉此就能夠在裝設加熱器單元132的機種與不裝設加熱器單元132的機種上，使用共通之水槽113用的模具。因此，能夠壓低用以實現溫水預格功能之開發時的製造成本。另外，能夠因應需要以外接方式設置加熱器單元132。In this way, the
又，如圖13、圖16所示，分隔壁146之垂直部146a的上端部位於比流入口134a更上方處。藉由作成這種構成，能夠抑制從流出路徑135b朝水槽113被排出之高溫的洗衣水進入流入路徑135a內，因此能夠有效率地將水槽內的洗衣水加熱。Moreover, as shown in FIG. 13, FIG. 16, the upper end part of the
另外，藉由每隔一定時間就使脈動器18旋轉，會攪拌水槽113內的洗衣水，能夠使水槽113內的水溫與加熱器收容容器內的水溫在短時間內達到均一。In addition, by rotating the
又，如圖16所示，加熱器收容容器137之水槽13側(上側)的內壁上表面139b是從加熱器***用開口部137b(參照圖12)朝向排水旋塞閥連接用開口部137a往水槽側(上側)逐漸傾斜。藉由此構成，在對加熱器收容容器137內供給洗衣水時，積蓄於加熱器收容容器137內的空氣將變得容易從加熱器收容容器137朝向水槽113被排出。因此，能夠防止加熱器收容容器137內的空氣積蓄，降低空燒的風險。 [4.其他實施形態]Also, as shown in FIG. 16, the
如以上所述，作為本申請中所揭示之技術的例示，說明了第1實施形態至第3實施形態。然而，本揭示之技術並不受此限，也能適用於進行過變更、置換、附加、省略等之實施形態。又，也能夠組合在上述第1實施形態至第3實施形態中所說明過的各構成要素，而作成新的實施形態。As described above, as an example of the technique disclosed in this application, the first embodiment to the third embodiment have been described. However, the technology of the present disclosure is not limited to this, and can also be applied to implementations in which changes, substitutions, additions, omissions, etc. have been made. In addition, it is also possible to combine the constituent elements described in the above-mentioned first embodiment to the third embodiment to create a new embodiment.
因此，以下例示其他實施形態。Therefore, other embodiments are exemplified below.
在第1實施形態中，雖然是藉由排水旋塞閥單元34與形成於加熱器收容容器37的流出路徑部37g，來構成水槽13與加熱器收容容器37間的連結路徑，但本發明並非限定於此。例如，亦可在加熱器收容容器37形成流入路徑部與流出路徑部，不透過排水旋塞閥單元34，將水槽13與加熱器收容容器37直接連通。此時，亦可在水槽13底部安裝有加熱器收容容器37的狀態下，將排水旋塞閥單元34連接於該狀態下之加熱器收容容器37的底面或側面。又，水槽13與加熱器收容容器37的連結路徑亦可設置3個以上。In the first embodiment, although the
