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 heater unit 32 of the washing machine in this embodiment will be described.

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 heater unit 32 is fixed to an outer bottom portion on the back side of the water tank 13 and a position where the back plate 17 can be removed for maintenance.

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開口插入;板金構件36,從加熱器收容容器37的第2開口插入,並覆蓋加熱器38;及蓋體51,覆蓋可供板金構件36插入的第2開口。As shown in FIG. 2, the heater unit 32 is composed of a heater storage container 37 having a substantially rectangular parallelepiped shape with openings at both ends in the longitudinal direction, and a heater 38 from the first opening of the heater storage container 37. Insertion; the sheet metal member 36 is inserted through the second opening of the heater accommodating container 37 and covers the heater 38; and the cover 51 covers the second opening through which the sheet metal member 36 can be inserted.

以下,針對各零件進行說明。 [A.加熱器收容容器37]Hereinafter, each component 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開口是插入加熱器38的加熱器插入用開口部37b,第2開口是插入板金構件36並藉由蓋體51加以覆蓋的板金構件插入用開口部37c。The heater storage container 37 is formed of a heat-resistant resin, and is formed in a substantially rectangular parallelepiped shape with openings at both ends in the longitudinal direction. Among the openings in the longitudinal direction of the heater accommodating container 37, the first opening is a heater insertion opening 37b into which the heater 38 is inserted, and the second opening is a sheet metal member inserted into the sheet metal member 36 and covered by the cover 51. The insertion opening 37c.

在加熱器收容容器37上表面的加熱器插入用開口部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 heater insertion opening 37b on the upper surface of the heater storage container 37, a cylindrical outflow path portion 37g communicating with the second drain port 33b at the bottom of the water tank 13 is formed.

在與具有流出路徑部37g之面鄰接的側面之板金構件插入用開口部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 plug valve connection opening 37 a that communicates with the drain plug valve unit 34 is formed near the sheet metal member insertion opening 37 c on the side adjacent to the surface having the outflow path portion 37 g. The drain plug valve unit 34 and the heater storage container 37 are attachable and detachable by screwing (not shown) or the like.

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 drain plug valve unit 34 is welded and fixed by a welding protrusion 45 at a position where the inflow port 34 a communicates with the first drain port 33 a at the bottom of the water tank 13. The water tank 13 and the heater storage container 37 are connected to each other through a drain plug valve unit 34. As shown in FIGS. 2, 3, and 4B, the drain plug valve unit 34 includes a drain-path-side opening portion 34 c. The drainage-path-side opening portion 34c is in communication with the drainage path 41 (see FIG. 1). By opening the drain valve (not shown) of the drain plug valve unit 34, the washing water in the water tank 13 and the heater storage container 37 is drained to the outside of the washing machine body 11 through the drain path 41.

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 water tank 13 and the drain plug valve unit 34 are fixed by welding, the present invention is not limited to this, and can be attached and detached by screwing or the like. [B. Sheet metal member 36]

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是從板金構件插入用開口部37c朝向前方插入加熱器收容容器37內。As shown in FIG. 2, the sheet metal member 36 surrounding the heater 38 is formed in a substantially rectangular parallelepiped shape with openings at both ends in the longitudinal direction. The sheet metal member 36 is inserted into the heater storage container 37 from the sheet metal member insertion opening 37 c toward the front.

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 heater 38 is transmitted through the sheet metal member 36 and diffused, it is possible to reduce the risk that the thermal energy is concentrated on a part of the heater storage container 37 and melted to cause a hole.

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 sheet metal member 36 is composed of two sheet metal parts. As shown in FIG. 2 and FIG. 6, one end of the sheet metal member 36 is spot-welded in a long-side spot welding portion 42. As shown in FIGS. 6 and 7, the other end of the sheet metal member 36 has a spacer 36 a that is not welded and has a certain gap. Therefore, the sheet metal member 36 is formed in a substantially U shape. The sheet metal member 36 is a support piece 40 that is recessed inward by bending. The support piece 40 fixes the heater 38 stored in the heater storage container 37 so as not to move.

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。A method for fixing the sheet metal member 36 and the heater storage container 37 will be described with reference to FIGS. 5, 6, and 7.

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插入加熱器收容容器37內的狀態下的間隔部36a之位置。在將板金構件36從板金構件插入用開口部37c朝向前方插入加熱器收容容器37內時,帶狀肋37d會位於間隔部36a。As shown in FIG. 5, a strip-shaped rib 37 d is formed on the inner wall of the heater storage container 37. The strip-shaped rib 37 d corresponds to the position of the spacer 36 a in a state where the sheet metal member 36 is inserted into the heater storage container 37. . When the sheet metal member 36 is inserted into the heater accommodating container 37 from the sheet metal member insertion opening 37 c toward the front, the band-shaped rib 37 d is positioned at the spacer portion 36 a.

如圖6、圖7所示,在板金構件36插入加熱器收容容器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 FIGS. 6 and 7, in a state where the sheet metal member 36 is inserted into the heater accommodating container 37, the width dimension W of the strip-shaped rib 37 d at the position where the sheet metal member 36 abuts is changed from the rear side toward the front side width.

圖7之帶狀肋37d的板金構件插入用開口部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的加熱器插入用開口部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,隨著從板金構件插入用開口部37c側(後側)朝向加熱器插入用開口部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從板金構件插入用開口部37c側(後側)朝向加熱器插入用開口部37b側(前側)插入,間隔部36a的間隔寬度會變狹窄。The width dimension W1 of the sheet metal member insertion opening 37c side (rear side) end of the strip-shaped rib 37d in FIG. 7 is formed to be larger than the gap width of the gap portion 36a in a state where the sheet metal member 36 is stored in the heater storage container 37. More narrow. The width dimension W2 of the heater insertion opening 37b side (front side) end of the strip-shaped rib 37d in FIG. 7 is formed to be wider than the gap width of the gap portion 36a in a state where the sheet metal member 36 is housed inside the heater housing container 37. width. As shown in FIG. 8, as the sheet metal member insertion opening portion 37c side (rear side) approaches the heater insertion opening portion 37b side (front side), the lower surface 39a of the inner wall of the heater housing container 37 moves toward Upward, and the upper surface 39b of the inner wall will gradually slope downward. Therefore, as the sheet metal member 36 is inserted from the sheet metal member insertion opening portion 37c side (rear side) toward the heater insertion opening portion 37b side (front side), the interval width of the spacer portion 36a becomes narrower.

藉由此構成,板金構件36在加熱器收容容器37內從板金構件插入用開口部37c側(後側)朝向加熱器插入用開口部37b側(前側)插入後,從插入途中開始,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 sheet metal member 36 is inserted from the sheet metal member insertion opening portion 37c side (rear side) toward the heater insertion opening portion 37b side (front side) in the heater housing container 37, and starts from the middle of the insertion. The width W of the rib 37d becomes wider than the interval width of the interval portion 36a of the sheet metal member 36. Therefore, by pressing the sheet metal member 36 to push it into the heater accommodating container 37, the end portion of the partition portion 36a of the sheet metal member 36 is fitted into the band-shaped rib 37d. In this way, the sheet metal member 36 can be supported and fixed in the heater storage container 37, and the sheet metal member 36 can be prevented from rattling during the spin-drying of the laundry-dehydration tank 15.

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, the sheet metal member 36 is configured by spot-welding two sheets of sheet metal, but for example, one sheet of metal may be formed. [C. Heater 38]

使用圖2,針對加熱器38進行說明。The heater 38 will be described using FIG. 2.

加熱器38是從加熱器收容容器37的加熱器插入用開口部37b插入。The heater 38 is inserted from the heater insertion opening 37 b of the heater storage container 37.

加熱器38是藉由加熱部38a、端子部38b及連接部38c所構成。The heater 38 is configured by a heating portion 38a, a terminal portion 38b, and a connection portion 38c.

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 heating portion 38 a is located inside the heater storage container 37 and generates heat energy for heating the laundry water in the heater storage container 37. As shown in FIG. 2, the heating portion 38 a is bent multiple times on the same plane. With this configuration, since the surface area of the heating portion 38a is increased, the washing water can be efficiently heated.

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 terminal portion 38b is electrically connected to the heating portion 38a. In addition, the terminal portion 38b is electrically connected to an external power source (not shown) and a control device (not shown) located outside the heater housing container 37. Power from an external power source is supplied to the heating portion 38a through the terminal portion 38b.

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之加熱器插入用開口部37b的大小。在圖8中,在加熱部38a插入加熱器插入用開口部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插入用開口部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插入用開口部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 connection portion 38c is interposed between the heating portion 38a and the terminal portion 38b. The connecting portion 38 c is provided with a flexible member 38 d having a size corresponding to the heater insertion opening 37 b of the heater housing container 37. In FIG. 8, in a state where the heating portion 38 a is inserted into the heater insertion opening portion 37 b, the heater 38 can be fixed in the heater storage container 37 by tightening the nut 43. That is, by tightening the nut 43, a force in a forward direction is applied to the bolt 44 and the crimping plate 47 welded to the bolt 44, so that the flexible member 38 d is compressed in the front-rear direction and expands in the surrounding direction. Therefore, the heater insertion opening 37b can be sealed. With this configuration, it is possible to prevent the washing water in the heater storage container 37 from leaking from the heater insertion opening 37b. The flexible member 38d is formed of a gasket such as rubber that can be elastically deformed.

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]As shown in FIG. 2, a temperature detection unit 56 is provided in the connection portion 38 c. The temperature detection unit 56 measures the temperature of the water in the heater storage container 37. The temperature detection unit 56 is composed of a thermistor or the like. [D. Cover 51]

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的板金構件插入用開口部37c。As shown in FIGS. 8 and 9, the cover 51 is a sheet metal member insertion opening 37 c detachably covering the heater housing container 37 with a screw lock (not shown).

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所覆蓋的板金構件插入用開口部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 confirm the inside of the heater accommodating container 37 by removing the cover body 51 and perform maintenance on the heater unit 32, the opening portion 37c for inserting the sheet metal member covered by the cover body 51 is provided with a rear opening in the washing machine body 11. The back side of the part 11a.

藉由蓋體51所覆蓋的板金構件插入用開口部37c是安裝於面對插入加熱器收容容器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 sheet metal member insertion opening 37 c covered by the cover 51 is attached to a position facing the heater 38 inserted into the heater accommodation container 37. With this configuration, the state of the heater 38 can be easily seen by removing the cover 51 from the heater housing container 37.

在蓋體51形成有傾斜肋51a,該傾斜肋51a是一種會將插入加熱器收容容器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,插入加熱器收容容器37內的板金構件36的板金構件插入用開口部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。插入加熱器收容容器37內的板金構件36的板金構件插入用開口部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 cover body 51 is formed with inclined ribs 51 a that are convex ribs that push the sheet metal member 36 inserted into the heater storage container 37 toward the inner wall surface side of the heater storage container 37. The inclined rib 51 a has an inclined surface facing the sheet metal member 36 stored in the heater storage container 37. The inclined surface approaches the heater storage container 37 from the “front” side indicated by the arrow in FIG. 8 to the “rear” side. The inner wall surface is inclined. With this configuration, the end portion on the sheet metal member insertion opening 37c side of the sheet metal member 36 inserted into the heater housing container 37 is expanded toward the inner wall lower surface 39a and the inner wall upper surface 39b by the inclined rib 51a. The sheet metal member insertion opening 37c side (rear) end of the sheet metal member 36 inserted into the heater housing container 37 is extended toward the inner wall lower surface 39a and the inner wall upper surface 39b by the inclined rib 51a.

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 addition, in a state where the heater storage container 37 is mounted on the bottom of the water tank 13, a rib portion 37 e (refer to FIG. 6). The rib 37e prevents the heat of the sheet metal member 36 heated by the heater 38 from being directly transmitted to the inner wall lower surface 39a and the inner wall upper surface 39b.

藉由此構成,在將板金構件36插入加熱器收容容器37內的狀態下,藉由蓋體51覆蓋板金構件插入用開口部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, in a state where the sheet metal member 36 is inserted into the heater accommodating container 37, the cover 51 covers the sheet metal member insertion opening 37c, and the sheet metal member 36 is covered by the inclined ribs 51a and the rib portions 37e. Support is fixed. Therefore, the sheet metal member 36 is prevented from rattling in the heater storage container 37.

像這樣進行來構成加熱器單元32。 [1-2.洗衣機的運轉動作]The heater unit 32 is configured in this manner. [1-2. Operation of washing machine]

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 door body 27, puts the laundry in the washing and dewatering tank 15 from the laundry input outlet 26, then closes the door body 27, and then operates the operation display portion 29 to start the warm water washing stroke.

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 is started, the water supply valve 30 is opened, and water is injected into the water tank 13 from the water injection tank 31. The injected water flows into the heater storage container 37 from the first drainage port 33 a and the second drainage port 33 b at the bottom of the water tank 13.

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 cycle, after the washing step using the heated water generated by the heater 38 is completed, the steps of rinsing and dehydrating are performed.

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 water tank 13 reaches a predetermined water level by filling the water tank 13, the heater 38 of the heater unit 32 is turned on. The control device controls the heater 38 to be turned on / off according to the water temperature of the washing water in the sink to control the temperature of the washing water. The water temperature detection method in the water tank will be described in [1-5. Water temperature detection method in the water tank].

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 temperature of the water in the water tank 13 reaches a predetermined temperature M1 (for example, 55 ° C.), the heater 38 is turned off. When the temperature of the measured water in the water tank 13 drops below a predetermined temperature M2 (for example, 53 ° C. or lower), the heater 38 is turned on. By this method, the washing water in the water tank 13 can be adjusted to a predetermined water temperature.

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。In addition, the predetermined temperatures M1 and M2 may be set according to each operation stroke (for example, a sterilization stroke or a sludge stroke). The predetermined temperatures M1 and M2 are changed in accordance with the running stroke, so that the washing water can be adjusted to a water temperature suitable for the purpose of each running stroke.

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。After the warm-water washing is completed, until the water temperature in the water tank 13 becomes lower than a predetermined temperature (for example, 50 ° C. or lower), the operation of adding water in the washing and dewatering tank 15 and stirring by the pulsator 18 may be repeated. When the temperature of the water in the water tank 13 becomes 50 ° C. or lower, the drain valve of the drain plug valve unit 34 is opened, and the washing water is drained to the outside of the washing machine body 11. When the water temperature in the water tank 13 becomes higher than a predetermined temperature (for example, 50 ° C. or higher) and the water level in the water tank 13 reaches a limit, temporary drainage is performed for a predetermined time.

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 drainage is discharged to the road surface, the safety can be improved because the washing water can be drained while the temperature of the water has been reduced.

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 outflow path 37g of the heater accommodating container 37 is blocked due to thread shavings of clothes, etc., there is a possibility that the water flow between the heater accommodating container 37 and the water tank 13 may be blocked. If the flow of water between the heater storage container 37 and the water tank 13 is blocked, it is conceivable that although the temperature of the water in the water tank is below the predetermined temperature M1, the heater unit 32 may become overheated. In this case, by controlling the heater 38 to be turned off when the measured water temperature of the temperature detecting section 56 that detects the water temperature in the heater storage container 37 reaches the heater overheating set temperature (for example, 95 ° C), it can be prevented Overheating in the heater unit 32 can suppress generation of scale and deterioration of the heater storage container 37. [1-3. Flow of washing water in heater unit]

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。The flow of washing water in the heater unit 32 when the heater 38 is turned on during the warm water washing cycle will be described using FIG. 10.

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。An outflow path portion 37g communicating with the bottom of the water tank 13 is formed on the root side of the heating portion 38a on the upper surface of the heater storage container 37, and is connected to a side of the front end portion of the heating portion 38a on the side of the heater storage container 37 A drain plug valve unit 34 communicating with the bottom of the water tank 13.

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 heater storage container 37 to increase the temperature of the water rises in the heater storage container 37.

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 distance from the heater 38 is closer to the outflow path portion 37g than the drain plug valve connection opening portion 37a, the temperature of the water in the heater housing container 37 is turned on with the power of the heater 38 turned on. The outflow path portion 37g may be higher than the drain plug valve connection opening portion 37a. Therefore, as shown by arrow D in FIG. 10, the washing water rising in the heater storage container 37 is discharged to the water tank 13 through the outflow path portion 37 g.

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 fill the high-temperature laundry water discharged from the heater storage container 37 toward the water tank 13, the low-temperature and heavy-weight laundry water in the water tank 13 is shown by arrow C in FIG. The drain plug valve of the unit 34 flows into the drain plug valve front path 34 b on the upstream side and flows into the bottom portion of the heater accommodation container 37. The washing water flowing into the heater accommodating container 37 is efficiently heated by the radiant heat of the heater 38 while flowing from the vicinity of the front end of the heating portion 38a of the heater 38 to the vicinity of the root portion. Therefore, the washing water can be efficiently heated.

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 (inlet port 34a, outflow path portion 37g) connecting the water tank 13 and the heater storage container 37 at positions different from the distance from the heater 38, the inside of each path can be used. The difference in the water temperature of the washing water is caused to circulate the washing water in the water tank 13 and the washing water in the heater storage container 37 by natural convection. Therefore, it is possible to reduce the number of parts without external force such as a pump, thereby reducing costs.

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 heater storage container 37 has a smaller capacity than the water tank 13, the washing water in the heater storage container 37 is heated by the heater 38 faster than the washing water in the water tank 13. The temperature change is high. Therefore, bacteria and the like contained in the washing water flowing into the heater storage container 37 can be effectively sterilized.

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 pulsator 18 at regular intervals, the washing water in the water tank 13 is stirred, and the temperature of the water in the water tank 13 can be made uniform.

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 the present embodiment, the larger the opening area of the first drainage port 33a and the second drainage port 33b can activate the circulation of the washing water of the heater unit 32 and the sink 13. However, if the first drainage port 33a and the second drainage port 33b are formed in a perfect circle shape and the opening area is enlarged, the welding protrusion 45 or the inner threaded screw around the first drainage port 33a and the second drainage port 33b will be caused. 46 and the like cause interference, so the bottom of the water tank 13 needs to be significantly remodeled.

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, as shown in FIG. 2, the first drainage opening 33 a is formed in a substantially elliptical shape, and the openings of the first drainage opening 33 a can be enlarged without changing the positions of the welding projection 45 and the inner screw 46. area. Therefore, it is not necessary to make a large investment in molds, and it is possible to efficiently circulate the washing water in the water tank 13 and the heater storage container 37 at a low cost.

又,如圖8所示,加熱器收容容器37底側的內壁下表面39a是從加熱器插入用開口部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]As shown in FIG. 8, the lower surface 39 a of the inner wall on the bottom side of the heater housing container 37 is gradually inclined downward from the heater insertion opening 37 b toward the drain plug valve connection opening 37 a. With this configuration, when draining, the washing water in the heater storage container 37 flows toward the drain plug valve connection opening 37a, and flows out to the washing machine body through the drain plug valve unit 34 and the drain path 41 (see FIG. 1). 11 outside. Therefore, it is possible to prevent the washing water or foreign matter in the heater housing container 37 from being trapped during drainage. [1-4. Status confirmation and maintenance method of heater unit]

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 large foreign matter such as line shavings generated from clothes may adhere to the heater 38 or block the outflow path portion 37g, there is a concern that the heated water in the heater storage container 37 may not flow out to the water tank 13. In addition, a defect may occur in the components of the heater unit 32. Therefore, it becomes necessary to confirm or repair the state in the heater unit 32 as necessary.

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, a method for confirming and maintaining the state in the heater unit 32 will be described.

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。To confirm the state of the heater unit 32, the back plate 17 covering the back opening 11a on the rear side of the washing machine body 11 is removed, and the lid of the heater storage container 37 mounted on the bottom surface of the water tank 13 is removed from the back opening 11a 51 removed. Since the heater accommodating container 37 and the lid body 51 are fixed by a screw lock, the lid body 51 can be removed by loosening the screws.

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。By this method, the state of the heater 38 in the heater accommodating container 37 can be confirmed from the opening portion 11 a on the back surface of the washing machine body 11, and the wire scraps and the like attached to the surface of the heater 38 can be removed as necessary. Therefore, since it is not necessary to attach or detach the lead connector connected to the heater 38, it becomes possible to easily confirm and maintain the heater 38.

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 sheet metal member 36, the sheet metal member 36 can be detached by withdrawing it from the heater storage container 37, and repair and replacement can be performed.

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 heater unit 32 and the water tank 13 and the heater unit 32 and the drain plug valve unit 34 are detachably mounted by being locked by screws or the like (not shown). With this configuration, when it is necessary to remove foreign objects invading the heater unit 32 or when it becomes necessary to replace the heater unit 32, the washing machine body 11 can be laid down horizontally, and the heating can be performed from the bottom of the washing machine body 11. The heater unit 32 is detached from the water tank 13 and the drain plug valve unit 34, and it becomes possible to perform maintenance of the heater unit 32 alone. Moreover, since only the broken parts of the heater unit 32 can be maintained, the time or cost required for repair can be reduced. [1-5. Water temperature detection method in water tank]

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 heater storage container 37 of the washing machine and the water temperature in the water tank 13 in the present embodiment.

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 heater 38 is turned on at time Ta0, the water in the heater storage container 37 is heated by the heater 38. Since the heater storage container 37 has a smaller volume than the water tank, the temperature of the water in the heater storage container 37 is generally 10 to 40 ° C higher than the temperature of the water in the water tank 13, but it is closed at time Ta1. After a predetermined time has passed by the heater 38, the temperature of the water in the water tank 13 and the temperature of the water in the heater accommodating container 37 gradually become uniform and become almost the same water temperature at time Ta2.

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 of estimating the water temperature in the water tank 13 using the temperature detection section 56 of the heater 38 will be described.

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 cycle, the heater unit 32 is turned on after the predetermined water level is reached by filling the water tank 13 with water. The time at this time is set to Ta0. Next, after the heater 38 is turned on and a predetermined time has elapsed (the time at this time is set to the time Ta1), the heater 38 is turned off. After the heater 38 is turned off, after a predetermined time has elapsed when the water temperature in the heater storage container 37 and the water temperature in the water tank 13 become substantially uniform (the time at this time is set to time Ta2), the temperature detection unit 56 to measure the temperature of the water in the heater storage container 37, thereby making it possible to estimate the temperature of the water in the water tank 13.

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 ON time of the heater 38 (the period from the time Ta0 to the time Ta1) should preferably be calculated from the output of the heater 38, the amount of water in the water tank 13, the amount of clothes, and the like. For example, the output of the heater is 1500W, the amount of water in the water tank 13 is 66L, and the amount of clothes is 5kg. When the initial water temperature is 20 ° C to a predetermined temperature of 55 ° C, it is about 130 minutes.

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 (period from time Ta1 to time Ta2) to turn off the heater 38 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 heater 38 is turned off for a predetermined time, the pulsator 18 is rotated for a predetermined time, thereby agitating the washing water in the water tank 13, which can promote the balance of the water temperature difference between the water tank 13 and the heater storage container 37. Therefore, the water temperature difference between the heater storage container 37 and the water tank 13 becomes smaller in a short time, and the water temperature in the water tank 13 can be detected with high accuracy.

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]According to this method, the temperature of the washing water in the water tank 13 can be adjusted using the temperature detection unit 56 that measures the temperature of the water in the heater storage container 37. Therefore, there is no need to provide a water temperature detection section in the water tank, and a highly reliable washing machine can be provided at a low cost. [2. Second Embodiment]

接著,針對本發明之第2實施形態中的洗衣機進行說明。Next, a washing machine in a 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 constituent parts of the washing machine in this embodiment are the same as those in the first embodiment, the same reference numerals are assigned to the same parts, and the description of each constituent part is omitted. [2-1. Water temperature control method in 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, a control method for adjusting the washing water in the water tank 13 to a predetermined target setting water temperature (for example, 53 ° C.) using the temperature detection unit 56 in the washing machine in this embodiment will be described.

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 washing machine body 11, a water tank 13 supported on the inside of the washing machine body 11 and having a drain port at the bottom, and a drain plug valve unit 34 connected to the drain port of the water tank 13. In addition, a heater unit 32 is connected to the drain plug valve unit 34 and communicates with the inner bottom of the water tank 13; a heater 38 is built in the heater unit 32 and heats the washing water; and a temperature detection unit 56 measures The temperature of the water in the heater unit 32. In addition, there is a control unit (not shown) that controls the energization of the heater 38 so that the washing water in the water tank 13 reaches a predetermined purpose to set the water temperature. After the water supply to the water tank 13 is completed, the control unit at least The first energization time of the heater 38 is calculated and determined from the water temperature and the amount of water supplied to the water in the water tank 13. During the first energization time, the heater 38 is energized. Here, the heater 38 may be continuously energized during the first energization period, or may be intermittently energized during the first energization period.

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 rise rate Vt of the washing water in the water tank 13 based on the measured temperature measured by the temperature detection unit 56 during the first energization time. In addition, the control unit calculates the second energization time of the heater 38 until the washing water in the water tank 13 reaches the target set water temperature from the temperature rise rate Vt and the water temperature in the water tank 13 after the end of the first energization time. Then, the control unit energizes the heater 38 during the calculated second energization time. Here, the heater 38 may be continuously energized during the second energization period, or may be intermittently energized during the second energization period.

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 period, after the heater 38 is continuously energized, the temperature of the water in the water tank 13 is estimated by the temperature detection unit 56 and compared with the target set water temperature. When the water temperature is lower than the target set water temperature, the heater 38 is energized for a predetermined time, and then the water temperature in the water tank 13 is estimated based on the temperature measured by the temperature detection unit 56 again. When the water temperature is higher than the target set water temperature, the heater 38 is not energized for a predetermined time, and then the water temperature in the water tank 13 is estimated again based on the measured temperature of the temperature detection unit 56.

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, it is possible to detect the overheating of the heater 38 and adjust the temperature of the washing water in the water tank 13 only by the temperature detection unit 56 provided in the heater storage container 37. Therefore, a highly reliable washing machine can be provided at a low cost. [3. Third Embodiment]

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 heater storage container 37 and the inner bottom surface of the water tank 13 are connected by two paths to circulate the heated washing water in the heater storage container 37 and the washing water in the water tank 13. However, in the first embodiment, it is necessary to provide a plurality of drain holes in the water tank 13. Therefore, the washing machine in the third embodiment is configured such that the heater storage container and the inner bottom surface of the water tank are connected by a single path.

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, a third embodiment will be described with reference to FIGS. 12 to 16. A longitudinal sectional view of the washing machine is referred 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 bottom of the water tank 13 of the washing machine in the first embodiment has first and second drainage ports 33a and 33b, the bottom of the water tank 113 of the washing machine in this embodiment has a drain port 133. Since the other configuration of the washing machine in this embodiment is the same as that of the washing machine in the first embodiment, the description is omitted. [3-1.

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 a heater unit of the washing machine in this embodiment. 13 is a cross-sectional view of a bottom surface of a sink, a drain plug valve unit, and a heater unit of a washing machine in the present embodiment. 14 and 15 are perspective views of a 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 heater unit 132 of the washing machine in this embodiment will be described.

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 heater unit 132 is fixed at a position where the back plate 17 (refer to FIG. 1) can be removed for maintenance at the bottom other than the back side of the water tank 113.

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的一開口插入;板金構件136,從加熱器收容容器137的另一開口插入,並覆蓋加熱器138;及蓋體151,覆蓋可供板金構件136插入的加熱器收容容器137之開口。As shown in FIG. 12, the heater unit 132 is composed of a heater storage container 137 having a substantially rectangular parallelepiped shape with openings at both ends in the longitudinal direction, and a heater 138 inserted through an opening of the heater storage container 137. The sheet metal member 136 is inserted from another opening of the heater storage container 137 and covers the heater 138; and the cover 151 covers the opening of the heater storage container 137 into which the sheet metal member 136 can be inserted.

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 component will be described. The heater 138 in this embodiment has the same configuration as the heater 38 in the first embodiment, and therefore description thereof is omitted. [A. Heater storage container 137]

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 heater storage container 137 is formed of a heat-resistant resin, and is formed in a substantially rectangular parallelepiped shape with openings at both ends in the longitudinal direction.

在加熱器收容容器137之長邊方向側的側面之板金構件插入用開口部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。A drain plug valve connection opening portion 137 a that is in communication with the drain plug valve unit 134 is provided near the sheet metal member insertion opening portion 137 c on the side in the longitudinal direction side of the heater storage container 137. Although in the washing machine in the first embodiment, a cylindrical outflow path portion 37g is formed on the upper surface of the heater storage container 37 and communicates with the second drainage opening 33b at the bottom of the water tank 13, the washing machine in this embodiment In the heater storage container 137, no such path is formed. The configuration of the other heater storage container 137 is the same as that of the heater storage container 37 of the first embodiment.

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 drain plug valve unit 134 is a drain port 133 detachably attached to the bottom of the water tank 113 with a screw or the like. As shown in FIG. 13, a part of the drain plug valve unit 134 is formed in an L-shape extending toward the heater storage container 137, and the water tank 113 and the heater storage container 137 are connected to each other through the drain plug valve unit 134. As shown in FIG. 13, the drain plug valve unit 134 is provided with a partition wall 146 which separates a path in the drain plug valve unit 134 from the water tank 113 to the heater storage container 137. The partition wall 146 is formed of a vertical portion 146a and a horizontal portion 146b extending from the lower end of the vertical portion 146a toward the heater 138, and is formed in an L-shaped cross section. With the partition wall 146, the water path in the drain plug valve unit 134 is separated into FIG. 13: the inflow path 135a is located to the left of the vertical portion 146a and below the horizontal portion 146b; and the outflow path 135b is located at the horizontal portion 146b Upper and right of the vertical portion 146a.

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插入水槽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 upper surface 139b of the inner wall of the heater housing container 137 and the inclination angle of the lower surface 139a of the inner wall are formed at approximately the same angle. With this configuration, as shown in FIGS. 14 and 15, even if the heater storage container 137 is turned upside down, it can be used by being inserted into the bottom of the water tank 113 through the drain plug valve unit 134. Therefore, the heater unit 132 can be arranged for each model of the washing machine in consideration of the center of gravity of vibration, the arrangement of parts, and the like. [B. Sheet metal member 136]

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 sheet metal member 136 surrounding the heater 138 is formed in a substantially rectangular parallelepiped shape having an opening at one end in the longitudinal direction. The sheet metal member 136 is formed by forming a single sheet metal member into a rectangular parallelepiped shape. As shown in FIG. 13, one end of the sheet metal member 136 in the longitudinal direction has a gap portion 136 a that is not welded and has a certain gap. A support sheet 140 that supports and fixes the heater 138 is welded to the inner surface of the sheet metal member 136. The support sheet 140 fixes the heater 138 stored in the heater storage container 137 so as not to move.

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。The sheet metal member 136 may be configured by, for example, welding two sheets of sheet metal by spot welding or the like.

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 sheet metal member 136 and the heater storage container 137 is the same as that of the first embodiment. [C. Lid 151]

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的板金構件插入用開口部137c。As shown in FIG. 13, the lid 151 is a sheet metal member insertion opening 137 c detachably covering the heater housing container 137 with a lock such as a screw (not shown).

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 cover body 51 of the washing machine in the first embodiment is formed with inclined ribs 51a (see FIG. 6) that are convex ribs, the cover body 151 of the washing machine in the present embodiment is not formed with this. Kind of ribs. The other structure of the cover body 151 in the second embodiment is the same as that of the cover body 51 in the first embodiment.

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]The heater unit 132 is configured in this manner. [3-2. Flow of washing water in heater unit]

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. The flow of washing water in the heater unit 132 in a state where the heater 138 is turned on during the warm water washing cycle will be described using FIG. 16.

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 drain plug valve unit 134 communicating with the bottom of the water tank 113 is connected to a side surface of the heater storage container 137 in the longitudinal direction. As shown in FIG. 13, a partition wall 146 is provided inside the drain plug valve unit 134. The partition wall 146 is formed in a substantially L-shape that extends downward toward the heater 138. The partition wall 146 can prevent low-temperature washing water and high-temperature washing water from being mixed in the drain plug valve 134, and efficiently circulate the washing water. The low-temperature washing water flows from the water tank 113 toward the heater storage container 137. The low-temperature washing water flowing into the path 135 a is the high-temperature washing water flowing from the heater storage container 137 toward the water tank 113.

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。In the state where the heater storage container 137 is filled with washing water, if the heater 138 is turned on, the washing water in the heater storage container 137 is heated by the heater 138, and rises in the heater storage container 137, as in The arrow B in FIG. 16 is discharged from the outflow path 135 b to the water tank 113.

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 fill the high-temperature laundry water discharged from the heater storage container 137 toward the water tank 113, the low-temperature and heavy-weight laundry water in the water tank 113 will flow through the inflow path 135a toward The heater storage container 137 flows into the container. Since the heated washing water in the heater storage container 137 moves upward, the low-temperature washing water in the water tank 113 easily flows into the bottom side of the heater storage container 137 from the inflow path 135a.

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 heater storage container 137 is heated by the heater 138, rises in the heater storage container 137, and flows out of the outflow path 135b to the water tank 113.

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 heater storage container 137 and the bottom of the water tank 113 are communicated through a path, and the washing water is circulated by natural convection caused by the temperature difference of the washing water, so that the heater unit 132 can be installed. For both the models and models without the heater unit 132, a common mold for the water tank 113 is used. Therefore, it is possible to reduce the manufacturing cost at the time of development for realizing the warm water pre-latching function. In addition, the heater unit 132 can be provided in an external manner as needed.

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。As shown in FIGS. 13 and 16, the upper end portion of the vertical portion 146 a of the partition wall 146 is located above the inflow port 134 a. With such a configuration, it is possible to suppress the high-temperature washing water discharged from the outflow path 135b toward the water tank 113 from entering the inflow path 135a. Therefore, the washing water in the water tank can be efficiently heated.

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 pulsator 18 at regular intervals, the washing water in the water tank 113 is stirred, and the water temperature in the water tank 113 and the water temperature in the heater storage container can be made uniform in a short time.

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是從加熱器插入用開口部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]In addition, as shown in FIG. 16, the upper surface 139b of the inner wall of the water tank 13 side (upper side) of the heater storage container 137 extends from the heater insertion opening 137b (see FIG. 12) toward the drain plug valve connection opening 137a. The sink side (upper side) is gradually inclined. With this configuration, when the washing water is supplied into the heater storage container 137, the air accumulated in the heater storage container 137 can be easily discharged from the heater storage container 137 toward the water tank 113. Therefore, the accumulation of air in the heater storage container 137 can be prevented, and the risk of air burn can be reduced. [4. Other embodiments]

However, the technology of the present disclosure is not limited to this, and can also be applied to embodiments in which changes, replacements, additions, and omissions are performed. In addition, it is also possible to create a new embodiment by combining the constituent elements described in the first to third embodiments.

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, the connection path between the water tank 13 and the heater storage container 37 is constituted by the drain plug valve unit 34 and the outflow path portion 37g formed in the heater storage container 37, but the present invention is not limited thereto herein.

在第3實施形態中,雖然在水槽113與加熱器收容容器137之間,是藉由排水旋塞閥單元134來構成連結路徑,但本發明並非限定於此。例如,亦可在加熱器收容容器137中形成與水槽113內底部之排水口連通的路徑部,藉此不透過排水旋塞閥單元134,將水槽113與加熱器收容容器137直接連通。此時,亦可在路徑部的內部配設分隔壁。又,藉由將加熱器收容容器137的路徑部以大致L字形狀形成,並將加熱器收容容器137的側面與水槽113內底面連通,水槽113內之低溫的洗衣水就會變得容易從流入路徑135a流入加熱器收容容器137底部側。再者,亦可在水槽113底部安裝有加熱器收容容器137的狀態下,將排水旋塞閥單元134連接於該狀態下之加熱器收容容器137的底面或側面。In the third embodiment, the connection path is formed by the drain plug valve unit 134 between the water tank 113 and the heater storage container 137, but the present invention is not limited to this. For example, the heater storage container 137 may be formed with a path portion communicating with a drain port at the bottom of the water tank 113, thereby directly communicating the water tank 113 and the heater storage container 137 without passing through the drain plug valve unit 134. In this case, a partition wall may be provided inside the path portion. In addition, by forming the path portion of the heater storage container 137 in a substantially L-shape, and communicating the side surface of the heater storage container 137 with the bottom surface of the water tank 113, the low-temperature washing water in the water tank 113 can be easily removed. The inflow path 135 a flows into the bottom side of the heater storage container 137. Furthermore, the drain plug valve unit 134 may be connected to the bottom surface or side surface of the heater storage container 137 in a state where the heater storage container 137 is installed at the bottom of the water tank 113.

在第3實施形態中,雖然說明了分隔壁146之垂直部146a的上端部位於比流入口134a更上方處的構成,但本發明並非限定於此,垂直部146a的上端部亦可位於比流入口134a更下方處。In the third embodiment, the configuration in which the upper end portion of the vertical portion 146a of the partition wall 146 is positioned above the inflow port 134a has been described, but the present invention is not limited to this. The entrance 134a is further down.

在第1實施形態、第3實施形態中,說明了在水槽13、113外底面安裝有加熱器單元32、132的狀態下,蓋體51、151是設置於加熱器收容容器37、137的位於洗衣機本體11之背面開口部11a的構成。蓋體51只要設置在加熱器收容容器37中的有洗衣機本體11的可開閉之開口存在的方向上即可。因此,藉由蓋體51、151所開閉的加熱器收容容器37、137的開口,可以形成於洗衣機本體11的前面側,亦可形成於洗衣機本體11的側面側。In the first embodiment and the third embodiment, it was described that the heater units 32 and 132 are mounted on the outer bottom surfaces of the water tanks 13 and 113, and the lids 51 and 151 are provided in the heater storage containers 37 and 137.
