Description

洗衣机 技术领域
本发明涉及一种能在持续进行脱水桶的旋转的情况下消除脱水桶的不平衡来抑制由脱水时的脱水桶的偏心引起的振动、噪音的洗衣机。
背景技术
以往，存在一种在洗涤脱水桶的内周面具有沿周向等间隔地配置的折流板的洗衣机(例如，参照专利文献1)。各折流板形成为从洗涤脱水桶的底部到上端部沿上下方向延伸。在折流板的下端部形成有在洗涤脱水桶的底部附近开口的开口部，在折流板的上端部形成有循环水口。因此，在清洗过程中，被波轮的下叶片部搅拌的洗涤水从开口部进入并在折流板内攀升，从循环水口吐出，对衣物进行浇洗。
洗衣机通常会在清洗过程之后进行脱水过程，但在脱水时洗涤物的偏倚大的情况下，旋转时的洗涤脱水桶的偏心变大，旋转需要大的转矩，因此无法开始脱水运转。因此，专利文献1中公开了如下技术：在脱水时检测洗涤脱水桶内的衣物的不平衡量和不平衡位置，在存在不平衡的情况下，通过向沿洗涤脱水桶的周向均等地设置的多个折流板进行注水来主动消除洗涤脱水桶的不平衡状态。
在专利文献1的洗衣机中，折流板形成为从脱水桶的内周面朝向内侧突出，还具有作为供调整水注入以便消除洗涤脱水桶的不平衡状态的注水管的作用。在像这样折流板从脱水桶的内周面突出的情况下，存在如下问题：脱水桶内的容积变小，并且在清洗过程中洗涤物在脱水桶内旋转时，洗涤物容易钩到脱水桶内的折流板而破损。
此外，在专利文献1那样的洗衣机中，虽然有时会采用提高了耐久性和清洁性的不锈钢脱水桶，但由于在折流板设于脱水桶的内周面的情况下，脱水桶 的内周面的大部分会被折流板遮挡，因此存在不锈钢脱水桶的有效性下降的问题。

发明效果
根据本发明，供调整水注入的注水部配置于脱水桶的外侧，因此与注水部形成于脱水桶的内侧的情况相比，脱水桶的投入口变大且脱水桶内的容积变大，并且能防止在清洗过程中洗涤物在脱水桶内旋转时，洗涤物钩到脱水桶内的注水部而破损。此外，由于即使在采用提高了耐久性和清洁性的不锈钢脱水桶的 情况下，脱水桶的内周面的大部分也不会像注水部形成于脱水桶的内侧的情况那样被注水部遮挡，因此能使脱水桶的整个内周面维持清洁。此外，在调整水注入至各注水部时，与注水部形成于脱水桶的内侧的情况相比，注水部与脱水桶的旋转轴的距离变大。因此，作用于注水部内的调整水的离心力变大，能有效地抵消偏心载荷。
根据本发明，通过将罩构件装配于脱水桶的外周面来设置注水部，因此无需像注水部形成于脱水桶的内侧的情况那样将两个树脂构件熔敷成箱状来形成注水部。因此，能降低洗衣机的制造成本。
根据本发明，通过将箱状的罩构件装配于脱水桶的外周面来设置注水部，能可靠地防止注水部内的调整水泄漏。
根据本发明，从脱水桶的通水孔朝向外侧流出的水流过形成于脱水桶的外周面与罩构件之间的间隙，因此能洗净脱水桶的外周面，能使脱水桶的外周面维持在干净的状态。
根据本发明，虽然在注水部形成于脱水桶的内侧的情况下，能通过脱水桶来承受作用于注水部的离心力，但在注水部形成于脱水桶的外侧的情况下，虽然由于通过来自脱水桶内侧的螺钉来承受作用于注水部的离心力而需要用于对注水部(罩构件)进行螺纹固定的凸台的强度，但罩构件不会与脱水桶内的洗涤物接触，因此能通过使用玻璃强化树脂来提高罩构件的强度。

具体实施方式
以下，基于附图对本发明的实施方式的洗衣机1进行详细说明。
(第一实施方式)
图1是表示本发明的第一实施方式的立式洗衣机(以下，称为“洗衣机”)1的外观的立体图。图2是表示本实施方式的洗衣机1的结构的示意图。图3是本实施方式的洗衣机1的内部的顶视图，图4是洗衣机1的内部的纵剖图。
本实施方式的洗衣机1具备洗衣机主体1a、脱水桶2、外桶3、注水装置30以及驱动部50。
图1所示的洗衣机主体1a为大致长方体形状。在洗衣机主体1a的上表面形成有用于向脱水桶2投入取出洗涤物的开口11，并且装配有能对该开口11进行开闭的开闭盖11a。
外桶3为配置于洗衣机主体1a的内部的有底筒状的构件，内部能贮留洗涤水。在外桶3的底面连接有排水配管3n。如图2所示，在外桶3的外周面3a装配有能检测水平和垂直这两个方向的加速度的加速度传感器58。在本实施方式中，由加速度传感器58来检测外桶3的加速度，而脱水桶2的加速度与外桶3的加速度大致相同。
脱水桶2兼任洗涤桶，是与外桶3同轴地配置于外桶3内并且被支承为自由旋转的有底筒状的构件。脱水桶2能在内部容纳洗涤物，在其内周面2a具有许多通水孔2t(参照图4)。
在这样的脱水桶2的底部2c中央，以自由旋转的方式配置有波轮(搅拌翼)4。如图2所示，波轮4具有大致圆盘形的波轮主体4a、形成于波轮主体4a的上表面的多个上叶片部4b以及形成于波轮主体4a的下表面的多个下叶片部4c。这样的波轮4对贮留于外桶3内的洗涤水进行搅拌来产生水流。
注水装置30是向后述的三个注水部8单独地注入调整水的装置。注水装置30具有分别连接于三个注水部8的三根注水软管30a，注水软管30a中分别配置有供水阀31a。注水软管30a设置为与三个注水部10数量相同，配置于与三个注水部10连通的接水环单元5的上方。本实施方式中使用自来水作为调整水。
如图2所示，接水环单元5具有朝向上方开放的环状的导水槽5a、5b、5c并固定于脱水桶2的上端部。导水槽5a、5b、5c设置为在径向上重叠三层，形成为单独使调整水流向任一个注水部8。
图2所示的驱动部50通过马达51来使带轮52和传动带53旋转，并且使朝向脱水桶2的底部2c伸出的驱动轴54旋转，对脱水桶2、波轮4赋予驱动力，使脱水桶2、波轮4旋转。洗衣机1在清洗过程中主要仅使波轮4旋转，在脱水过程中使脱水桶2和波轮4一体地高速旋转。此外，在一方的带轮53的附近设有能检测形成于带轮52的标记52a的通过的接近开关55。
如图3和图4所示，在脱水桶2的内周面2a沿周向等间隔(等角度)地设有三个折流板6。各折流板6为中空状，横截面形状形成为圆弧状。如图2所示，各折流板6形成为：从脱水桶2的底部2c到上端部沿上下方向延伸，从脱水桶2的内周面2a朝向脱水桶2的旋转轴S1突出。在折流板6的上端部形成有横向长的循环水口6a。
此外，在折流板6的下端部形成有开口部6c，该开口部6c在脱水桶2的底部2c附近开口，更具体而言在比波轮主体4a靠下方处开口。各折流板6在清洗过程中使被波轮4的下叶片部4c搅拌的洗涤水通向脱水桶2的上端部并从循环水口6a吐出。
因此，在处于装配于排水配管3n的排水阀3n a(参照图2)关闭而外桶3内贮有洗涤水的状态的清洗过程中，如图2中的箭头所示，被波轮4的下叶片部4c搅拌的洗涤水从开口部6c进入并在折流板6内攀升，从循环水口6a吐出，对衣物进行浇洗。通过反复进行该动作，洗涤水在脱水桶2内循环。
此外，如图3所示，在脱水桶2的外周面2b设有三个注水部8，该注水部8供调整水注入以便在脱水过程中消除脱水桶2的不平衡状态。注水部8沿周向等间隔(等角度)地设于脱水桶2的外周面2b。各注水部8为中空状，横截面形状形成为圆弧状。注水部8的周向中央部配置于折流板6的周向中央部的径向外侧。各注水部8和各折流板6形成为各自分开的空间。
具体而言，在脱水桶2的外周面2b装配有三个罩构件10。三个罩构件10与脱水桶2一体地旋转。如图5所示，罩构件10是以具有与脱水桶2的外周面2b大致相同的曲率的方式弯曲成圆弧状的构件。罩构件10例如由含玻璃树脂形成。罩构件10为其内侧面开放的构件，具有大致矩形的外壁部11和以与外壁部11一体地从外壁部11的下端部向下方延伸的方式形成的排水部12。排水部12在左右方向延伸的宽度小于外壁部11在左右方向延伸的宽度。排水部12的左右方向中央部以与外壁部11的下端部的左右方向中央部一致的方式配置。需要说明的是，罩构件10通过螺栓来装配于脱水桶2的外周面2b，该螺栓从径向内侧向径向外侧插入至形成于脱水桶2的内周面2a的装配孔中。
在罩构件10的内周面(在罩构件10装配于脱水桶2的外周面2b时与脱水桶2的外周面2b对置的面)形成有凹部13。因此，当将罩构件10装配于脱水桶2的外周面2b时，在罩构件10的内周面与脱水桶2的外周面2b之间形成有作为供调整水注入的空间的注水部8。注水部8以沿着脱水桶2的外周面2b的方式形成。需要说明的是，如图4所示，在脱水桶2的外周面2b，在供罩构件10装配的部分(图4中由虚线包围的范围)不形成通水孔2t。
在各罩构件10的上端装配有用于注入调整水的注水管16，注水管16连接于接水环单元5的导水槽5a、5b、5c中的任一个。因此，当在罩构件10装配于脱水桶2的外周面2b的状态下向注水部8内注入了调整水时，调整水在通过外壁部11的内部后，通过排水部12的内部从排水部12的下端进行排水。
在罩构件10的内周面，在外壁部11的下端部设有弯曲成圆弧状的接水板 18。接水板18为板状，以从外周壁11的内周面突出的方式形成。接水板16以其上表面呈大致水平的方式形成。
像这样，在罩构件10装配于脱水桶2的外周面2b的状态下，接水板18在注水部8的内部从外周壁11朝向内侧突出，但接水板18的突出量小于凹部13的深度。因此，在外壁部11的下端部(排水部12的上端部)，在接水板18的顶端(径向内侧端部)与脱水桶2的外周面2b之间形成有空隙，处于外壁部11的内部的调整水经由该空隙从接水板18流向下方。
需要说明的是，在脱水过程中，当在脱水桶2旋转的状态下向注水部8注入了调整水时，调整水因离心力而贴附于罩构件10的外周壁11的内周面，因此调整水被保持于注水部8内的比接水板18靠上方的位置。
与此相对，在脱水过程中，当脱水桶2的转速变小时离心力变小，被保持于接水板18的上方的调整水不再贴附于罩构件10的外周壁11的内周面，而经由接水板18的顶端与脱水桶2的外周面2b之间的间隙进行排水。
图6的(a)示出了表示本实施方式的洗衣机1的内部的局部的截面的示意图，图6的(b)示出了表示现有的洗衣机501的内部的局部的截面的示意图。
在本实施方式的洗衣机1中，如图6的(a)所示，注水部8设于脱水桶2的外周面2b与外桶3的内周面之间。因此，与如图6的(b)所示注水部8设于脱水桶2的内周面2a的内侧的情况相比，设于脱水桶2的上端部的接水环单元5的位置配置于径向外侧。由此，本实施方式的洗衣机1中，形成于接水环单元5的内侧的投入口的大小(面积)比注水部8设于脱水桶2的内周面2a的内侧的情况大。
在本实施方式的洗衣机1中，当接近开关55感测到标记52a(参照图2)时，根据来自加速度传感器58的水平方向和垂直方向的加速度的大小计算不平衡量，并且根据来自加速度传感器58的表示水平方向和垂直方向的加速度的信号和从接近开关55输入的表示标记52a的位置的信号计算不平衡方向的角度。
基于表示不平衡量和不平衡位置的信号，基于预先储存的控制程序来判断要向脱水桶2内的哪个注水部8进行供水及其供水量。需要说明的是，关于向脱水桶2内的哪个注水部8进行供水，会选定在脱水桶2内处于与作为不平衡 的主要原因的洗涤物的团块所在的位置对置的位置的注水部8。然后打开与选定的注水部8连接的供水阀31a，进行调整水的注水，在通过注水部8消除了不平衡时，停止调整水的注水。
如上所述，本实施方式的洗衣机1具备：脱水桶2，配置于外桶3内；三个以上的注水部8，沿周向等间隔地配置于脱水桶2的外周面2b；以及注水装置30，能向各个注水部8注入调整水。
当采用这样的结构时，由于供调整水注入的注水部8配置于脱水桶2的外侧，因此与注水部8形成于脱水桶2的内侧的情况相比，脱水桶2的投入口变大且脱水桶2内的容积变大，并且能防止在清洗过程中洗涤物在脱水桶2内旋转时，洗涤物钩到脱水桶2内的注水部8而破损。此外，由于即使在采用提高了耐久性和清洁性的不锈钢脱水桶的情况下，脱水桶2的内周面2a的大部分也不会像注水部8形成于脱水桶2的内侧的情况那样被注水部8遮挡，因此能使脱水桶2的整个内周面2a维持清洁。此外，在调整水注入至各注水部8时，与注水部8形成于脱水桶2的内侧的情况相比，注水部8与脱水桶2的旋转轴S1的距离变大。因此，作用于注水部2内的调整水的离心力变大，能有效地抵消偏心载荷。
本实施方式的洗衣机1中，脱水桶2具有装配于其外周面2b的罩构件10，注水部8设于罩构件10与脱水桶2的外周面2b之间。
当采用这样的结构时，通过将罩构件10装配于脱水桶2的外周面来形成注水部8，因此无需像注水部8形成于脱水桶2的内侧的情况那样将两个树脂构件熔敷成箱状来形成注水部8。因此，能降低洗衣机1的制造成本。
本实施方式的洗衣机1中，罩构件10由含玻璃树脂形成。
当采用这样的结构时，在注水部8形成于脱水桶2的内侧的情况下能通过脱水桶2来承受作用于注水部8的离心力，而在注水部8形成于脱水桶2的外侧的情况下，虽然由于通过来自脱水桶2内侧的螺钉承受作用于注水部8的离心力而需要用于对注水部8(罩构件10)进行螺纹固定的凸台的强度，但罩构件10不会与脱水桶2内的洗涤物接触，因此能通过使用玻璃强化树脂来提高罩构件10的强度。
(第二实施方式)
本实施方式的洗衣机101与第一实施方式的洗衣机1不同之处在于：在第一实施方式中，注水部8设于罩构件10与脱水桶2的外周面2b之间，而在本实施方式中，注水部108设于配置于比脱水桶2的外周面2b靠外侧的位置的箱状的罩构件110的内部。需要说明的是，对于本实施方式的洗衣机101的结构中与第一实施方式的洗衣机1的结构同样的部分，省略详细的说明。
图7是本发明的第二实施方式的立式洗衣机101的内部的顶视图，图8是洗衣机101的内部的纵剖图，图8的(b)是由图8的(a)的实线包围的部分的放大图。
在本实施方式的洗衣机101的脱水桶2的外周面2b内设有三个注水部108，该注水部108供用于在脱水过程中消除脱水桶2的不平衡状态的调整水注入。注水部108沿周向等间隔(等角度)地设于脱水桶2的外周面2b。各注水部108为中空状，横截面形状形成为圆弧状。注水部108的周向中央部配置于折流板6的周向中央部的径向外侧。各注水部8和各折流板6形成为各自分开的空间。
具体而言，在脱水桶2的外周面2b装配有三个罩构件110。三个罩构件110与脱水桶2一体地旋转。如图9所示，罩构件110是以具有与脱水桶2的外周面2b的大致相同的曲率的方式弯曲成圆弧状的构件。罩构件110例如由含玻璃树脂形成。罩构件110具有其内侧面开放的开放构件10和熔敷于开放构件10的内侧的闭塞构件110a。开放构件10与第一实施方式的罩构件10为大致相同形状，因此省略详细的说明。需要说明的是，罩构件110通过从脱水桶内侧对形成于闭塞构件110a的凸台进行螺纹固定来装配于脱水桶2的外周面2b。
闭塞构件110a具有大致矩形的内壁部113和以与内壁部113一体地从内壁部113的下端部向下方延伸的方式形成的排水部114。内壁部113为与外壁部11大致相同的大小，排水部114为与排水部12大致相同形状的大小。因此，通过将闭塞构件110a以其内壁部113与外壁部11对置且排水部114与排水部12对置的方式熔敷于开放构件10的内周面，在开放构件10与闭塞构件110a之间形成有作为供调整水注入的空间的注水部108。如此，罩构件110形成为箱状。
此外，在闭塞构件110a的内周面形成有五个突起部113a。在罩构件110装 配于脱水桶2的外周面2b的状态下，突起部113a以从闭塞构件110a的内周面朝向脱水桶2的外周面2b突出的方式形成。五个突起部113a弯曲成圆弧状并以在上下方向上分离的方式配置。当将罩构件110装配于脱水桶2的外周面2b时，形成于闭塞构件110a的内周面的五个突起部113a的顶端抵接于脱水桶2的外周面2b，由此在罩构件110的内周面(闭塞构件110a的内周面)与脱水桶2的外周面2b之间形成有具有与突起部113a的高度大致相同的宽度的间隙T。
需要说明的是，如图8所示，在脱水桶2的外周面2b，在供罩构件110装配的部分(图8中由虚线包围的范围)形成有通水孔2t。因此，在脱水过程中脱水桶2旋转时，脱水桶2内的水经由通水孔2t向间隙T流出，该水以沿圆周方向蔓延的方式流动。
本实施方式的洗衣机101能得到与第一实施方式的洗衣机1同样的效果。
本实施方式的洗衣机101中，脱水桶2具有装配于其外周面2b的箱状的罩构件110，注水部108设于罩构件110的内部。
根据本发明，通过将箱状的罩构件110装配于脱水桶2的外周面2b来设置注水部108，因此能可靠地防止注水部108内的调整水泄漏。
本实施方式的洗衣机101中，在脱水桶2的外周面2b与罩构件110之间形成有间隙T。
根据本发明，从脱水桶2的通水孔2t朝向外侧流出的水会流过形成于脱水桶2的外周面2b与罩构件110之间的间隙T，因此能洗净脱水桶2的外周面2b，能使脱水桶2的外周面2b维持在干净的状态。
以上，对本发明的实施方式进行了说明，但本实施方式的结构并不限定于上述内容，可以进行各种变形。
例如，在上述第一实施方式中，在脱水桶2的外侧设有与设于脱水桶2的内侧的三个折流板6相同数量的三个注水部8，但并不限于此。设于脱水桶2的外侧的注水部8的数量是任意的。此外，注水部8中，其左右方向中央部配置于折流板6的左右方向中央部的径向外侧，但注水部8和折流板6的位置是任意的。注水部8的数量与折流板6的数量也可以不同。此外，也可以在未设置折流板6的脱水桶2的外侧设置注水部8。这一点对于上述第二实施方式也同样 如此。
在上述第一实施方式中，通过将内侧面开放的罩构件10装配于脱水桶2的外周面来将注水部8设置于脱水桶2的外侧，在上述第二实施方式中，通过将箱状的罩构件110装配于脱水桶2的外周面来将注水部108设置于脱水桶2的外侧，但并不限于此。在上述的第一实施方式和第二实施方式中，注水部8、108只要设于脱水桶2的外侧且设置为与脱水桶2一体地旋转即可，用于设置注水部8、108的罩构件10、110的结构(例如形状、大小等)是任意的。
在上述第二实施方式中，在脱水桶2的外周面2b与罩构件110之间形成有间隙T，但并不限于此。例如，在罩构件110的闭塞构件110a的内周面未形成突起部113a的情况下，罩构件110也可以以不在罩构件110与脱水桶2的外周面2b之间形成间隙T的方式装配。
在上述的第一实施方式和第二实施方式中，对罩构件10、110由含玻璃树脂形成的情况进行了说明，但罩构件10、110的材质是任意的。
其他的结构也可以在不脱离本发明的主旨的范围内进行各种变形。
