Description

洗衣机 技术领域
本发明涉及一种能在脱水桶旋转持续的状态下消除脱水桶的不平衡来抑制因脱水时脱水桶的偏心而引起的振动、噪音的洗衣机。
背景技术
设置于普通家庭或自助洗衣店等的普通洗衣机具有在内周面形成有许多通水孔的脱水桶。因此，在脱水时从脱水桶内的洗涤物脱水出的水会经由许多通水孔被排向脱水桶的外部。此外，在脱水时洗涤物的偏倚大的情况下，旋转时的脱水桶的偏心会变大，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，向均匀设于脱水桶的周向的多个折流板进行注水，由此主动消除脱水桶的不平衡状态。
在专利文献1的洗衣机中，在脱水桶的内周面设有多个折流板，因此存在脱水桶的投入口的面积和脱水桶内的容积变小的问题。作为在维持向折流板内的可注水量的状态下克服该问题的方法，可以考虑使折流板的厚度变薄并与之相应地使折流板在周向上变宽。然而，在使折流板在周向上变宽了的情况下，形成于脱水桶的内周面的通水孔的数量会变少，因此无法在脱水时高效地将从脱水桶内的洗涤物中脱水出的水经由通水孔向脱水桶的外部排出。

发明内容
发明所要解决的问题
本发明能提供一种能在脱水时高效地将从洗涤桶内的洗涤物中脱水出的水向脱水桶的外部排出的洗衣机。
用于解决问题的方案
本发明的洗衣机的特征在于，具备：脱水桶，底部配置有波轮，在所述脱水桶的内周面形成有多个通水孔；三个以上的折流板，在周向上等间隔地配置于所述脱水桶的内周面；以及注水装置，能向各折流板独立地注入调整水，在所述折流板的内部形成有从其外周侧壁向径向内侧突出的接水板，所述折流板具有：蓄水空间，配置于比所述接水板靠上方处，蓄留调整水；以及排水空间，配置于比所述接水板靠下方处，将从所述蓄水空间流出的调整水排水，所述蓄水空间的周向长度形成为比所述排水空间的周向长度长，所述蓄水空间的内周面具有以越是趋向下方越配置于径向外侧的方式倾斜的倾斜面，并且在所述脱水桶中所述排水空间的周向两侧区域配置有所述通水孔。
在本发明的洗衣机中，优选的是，在所述蓄水空间的内周面的下端部附近形成有使水流向所述排水空间的周向两侧分流的分流部。
在本发明的洗衣机中，优选的是，形成于所述脱水桶中所述排水空间的周向两侧区域的所述通水孔的开口面积从方上往下方变小。
在本发明的洗衣机中，优选的是，在所述脱水桶的内周面与所述折流板的背面之间形成有间隙，并且在所述脱水桶的内周面中与所述折流板的背面对置的部分配置有所述通水孔。
发明效果
根据本发明，由于折流板的蓄水空间的内周面具有以越是趋向下方越配置于径向外侧的方式倾斜的倾斜面，因此，即使在折流板在周向上变宽的情况下，在脱水时从脱水桶内的洗涤物中脱水出的水也会被引导向蓄水空间的下方。这样一来，由于在蓄水空间的下方配置有通水孔，因此会高效地将从洗涤物脱水出的水向脱水桶的外部排出。因此，能在脱水时顺畅地进行脱水。而且，从洗涤物中脱水出的水会从脱水桶的下部被集中排水，因此，排出的水不易蓄留于外桶与脱水桶之间，能顺畅地导向外桶的排水孔。
根据本发明，在蓄水空间的内周面的下端部附近形成有使水流向排水空间 的周向两侧分流的分流部，因此能将从洗涤物中脱水出的水导向配置于蓄水空间的下方的通水孔，能更顺畅地排水。
根据本发明，形成于脱水桶中排水空间的周向两侧区域的通水孔的开口面积从上方往下方变小，因此能在脱水时更顺畅地排水。
根据本发明，在脱水时从脱水桶内的洗涤物中脱水出的水会从折流板的左右两端部绕到背面侧，通过脱水桶的内周面与折流板的背面之间的间隙，从通水孔向脱水桶的外部高效地排出。

具体实施方式
以下，基于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的洗衣机(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是从上方观察本实施方式的洗衣机1的局部的俯视图。图4是洗衣机1所具有的脱水桶2的横剖图。
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、接水环单元5、注水装置30(喷嘴单元)、驱动部50以及控制单元60(参照图6)。
图1所示的洗衣机主体1a呈大致长方体形状。在洗衣机主体1a的上表面形成有用于使洗涤物出入于脱水桶2的开口11并且安装有能开闭该开口11的开闭盖11a。
外桶3是配置于洗衣机主体1a的内部的有底筒状的构件，能在内部蓄留洗涤水。在外桶3的底面形成有排水口10，在排水口10连接有排水配管10a。如图2所示，在外桶3的外周面3a安装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56。
脱水桶2是与外桶3同轴地配置在外桶3内并且被支承为旋转自如的有底筒状的构件。脱水桶2能在内部容纳洗涤物，其壁面2a具有许多通水孔2t(参照图5的(a))。
在这样的脱水桶2的底部2c中央旋转自如地配置有波轮(搅拌翼)4。如图2所示，波轮4具有：大致圆盘形状的波轮主体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对蓄于外桶3内的洗涤水进行搅拌而产生水流。
如图4所示，在脱水桶2的内周面2a1，在周向上等间隔(等角度)地设有三个作为通水管部的折流板(注水管)8。各折流板8形成为沿上下方向从脱水 桶2的底部2c延伸至上端部并从脱水桶2的内周面2a1向轴线S1突出。此外，各折流板8呈中空状，横截面形状形成为圆弧状。如此，折流板8的形状为向脱水桶2的轴线S1的突出较小并沿脱水桶2的周向扩展的形状，由此能抑制脱水桶2的容纳空间变窄。
如图2所示，在这样的折流板8的上端部形成有横向长的循环水口80。此外，在折流板8的下端部形成有开口部81，该开口部81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。
因此，在处于排水阀10a 1(参照图2)被关闭且外桶3内蓄有洗涤水的状态的清洗过程中，如图2中以箭头所示，被波轮4的下叶片部4c搅拌的洗涤水从开口部81进入并在折流板8内上升，从循环水口80被吐出，对衣物进行喷淋洗涤。此外，通过重复该动作，洗涤水在脱水桶2内循环。即，折流板8具有洗涤水的循环功能。
在折流板8内的上端附近设有从循环水口80延伸至脱水桶2的内周面2a1的接近位置的分隔片8a。分隔片8a从循环水口80的上端缘向半径方向外侧延伸，然后向下方弯曲。在这样的分隔片8a与脱水桶2的内周面2a1之间形成有间隙8b(参照图2)，从接水环单元5供给的调整水经由间隙8b流入下方。
如图3所示，接水环单元5是由向上方开放的环状的导水槽5a、5b、5c向脱水桶2的轴线S1沿径向重叠三层而构成的构件，如图2所示固定于脱水桶2的内周面2a1的上端部。导水槽5a、5b、5c设为与折流板8数量相同，形成为使调整水独立流入任一个折流板8。
如图3所示，在导水槽5a的下端部形成有向径向外侧开口的开口5A，导水槽5a和折流板8的内部连通。在导水槽5b的下端部形成有向径向外侧开口的开口5B，导水槽5b和折流板8的内部经由穿过导水槽5a的下方的通水路径5Ba连通。在导水槽5c的下端部形成有向径向外侧开口的开口5C，导水槽5c和折流板8的内部经由穿过导水槽5a和导水槽5b的下方的通水路径5Ca连通。
在接水环单元5的外周侧安装有环状的流体平衡器12。流体平衡器12与已知的流体平衡器相同。
注水装置30是向这样的导水槽5a、5b、5c独立地注入调整水的构件。注水 装置30具有配置于导水槽5a、5b、5c的上方的三根注水喷嘴30a、30b、30c和分别连接于这些注水喷嘴30a、30b、30c的供水阀31a、31b、31c。注水喷嘴30a、30b、30c设为与导水槽5a、5b、5c数量相同，分别安装于外桶3的上端部中能向各个导水槽5a、5b、5c注水的位置。需要说明的是，在本实施方式中，调整水可以使用自来水。此外，供水阀31a、31b、31c可以采用方向切换供水阀。
图2所示的驱动部50通过马达51来使带轮52和带53旋转，并且使向脱水桶2的底部2c延伸的驱动轴54旋转，为脱水桶2、波轮4提供驱动力，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。
图5的(a)是从内周侧观察形成于脱水桶2的内周面2a1的折流板8的图，图5的(b)是图5的(a)的a 1－a 1线处的剖视图，图5的(c)是图5的(a)的a 2－a 2线处的剖视图。
如图5的(b)所示，在折流板8的内周侧壁的下端附近具有向径向内侧突出的突出壁部82。即，折流板8的内周侧壁的局部向径向内侧突出。如图5的(a)和图5的(b)所示，在折流板8的内部形成有从其外周侧壁向径向内侧突出的接水板85。
接水板85配置于与突出壁部82相同高度，接水板85的径向内侧端部85a配置于突出壁部82的内部。在接水板85的径向内侧端部85a与突出壁部82的顶端内周面之间形成有空隙，供给至蓄水空间8Ta的调整水经由该空隙流入排水空间8Tb。
折流板8的内部空间具有：蓄水空间8Ta，配置于比配置有接水板85的突出壁部82靠上方处；以及排水空间8Tb，配置于比突出壁部82靠下方处。蓄水空间8Ta是蓄留来自导水槽5a、5b、5c的调整水的空间，排水空间8Tb是将从蓄水空间8Ta流出的调整水排水的空间。
如图5的(a)和图5的(b)所示，蓄水空间8Ta的径向厚度与排水空间8Tb的径向厚度大致相同，相对于此，排水空间8Tb的上下方向长度比蓄水空间8Ta的上下方向长度短。蓄水空间8Ta的周向长度形成为比排水空间8Tb的 周向长度长。因此，蓄水空间8Ta的体积比排水空间8Tb的体积大。
注入折流板8的蓄水空间8Ta的调整水由配置于突出壁部82内的接水板85以不会流向下方的方式保持，沿着接水板85的上表面在突出壁部82内向径向内侧流动。当在脱水桶2旋转的状态下向折流板8的蓄水空间8Ta注入调整水时，调整水因离心力而贴附于导水槽5a、5b、5c的外周壁，因此调整水被保持在蓄水空间8Ta内。
在图5的(b)和图5的(c)中，沿上下方向延伸的虚线表示穿过蓄水空间8Ta的下端且与铅垂方向平行的直线。如图5的(b)和图5的(c)所示，蓄水空间8Ta的内周面以越是从其下端趋向上端越向径向内侧配置的方式倾斜。即，蓄水空间8Ta的内周面形成为以越是从上端趋向下端越配置于径向外侧的方式倾斜的倾斜面A。在本实施方式中，蓄水空间8Ta的内周面的整个区域为倾斜面A。
如图5的(a)所示，在脱水桶2中排水空间8Tb的周向两侧区域，与脱水桶2的内周面2a1中未形成折流板8的区域同样地配置有多个通水孔2t。
配置于接近蓄水空间8Ta的下端的区域的通水孔2t的直径大，形成于接近脱水桶2的底部2c的区域的通水孔2t的直径小。即，分别配置于排水空间8Tb的周向两侧区域的通水孔2t的直径从上方往下方变小。
此外，形成于脱水桶2的内周面2a1中未形成折流板8的区域的通水孔2t的直径与形成于接近脱水桶2的底部2c的区域的通水孔2t的直径大致相同。
因此，若将通水孔2t的开口率设为规定面积的通水孔2t的开口的比例，则排水空间8Tb的周向两侧区域的通水孔2t的开口率比脱水桶2的内周面2a1中未形成折流板8的区域的通水孔2t的开口面积大。排水空间8Tb的周向两侧区域的通水孔2t的开口率从上方往下方变小。
如图5的(a)和图5的(b)所示，在本实施方式的洗衣机1中，在脱水桶2的内部于脱水时脱出的水因离心力而被按压至蓄水空间8Ta的内周面，变得容易流向以比蓄水空间8Ta的上端靠径向外侧的方式配置的蓄水空间8Ta的下端。然后，在脱水时脱出的水从形成于排水空间8Tb的周向两侧区域的通水孔2t向脱水桶2的外部排出，被导向外桶3的排水孔。
图6是表示本实施方式的洗衣机1的电气结构的框图。该洗衣机1的动作由包括微型计算机的控制单元60控制。控制单元60具备负责系统整体的控制的中央控制部(CPU)61，在该控制单元60连接存储有各种设定值等的存储器62。此外，通过控制单元60来使微型计算机执行存储于存储器62中的程序，由此进行预先设定的运转动作，并且存储器62中临时存储有执行上述程序时所使用的数据等。
中央控制部61向转速控制部63输出控制信号，进而将该控制信号输出给马达控制部(马达控制电路)64来进行马达51的旋转控制。需要说明的是，转速控制部63从马达控制部64实时地输入表示马达51的转速的信号，成为控制要素。将加速度传感器56连接于不平衡量检测部65，并且将加速度传感器56和接近开关55连接于不平衡位置检测部66。
由此，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56的水平方向和垂直方向的加速度的大小，在不平衡量检测部65中计算出不平衡量(M)，该不平衡量被输出给不平衡量判定部67。不平衡位置检测部66根据从接近开关55输入的表示标记52a的位置的信号来计算出不平衡方向的角度，将不平衡位置信号输出给注水控制部68。
当被输入了来自不平衡量判定部67和不平衡位置检测部66的表示不平衡量和不平衡位置的信号时，注水控制部68基于预先存储的控制程序来判断是否向脱水桶2内的任一个折流板8进行供水及其供水量。然后，打开所选定的供水阀31a、31b、31c开始调整水的注入。在脱水桶2中产生不平衡时，开始基于该不平衡量的计算，从选定的注水喷嘴30a、30b、30c向接水环单元5的导水槽5a、5b、5c注入调整水，并在通过折流板8消除了不平衡时停止调整水的注入。
需要说明的是，例如，如图4所示，在成为不平衡的主要原因的洗涤物的团块D(X)位于脱水桶2的折流板8(A)与折流板8(C)之间的情况下，注水控制部68以向折流板8(B)供给调整水的方式进行控制。此外，在洗涤物的团块D(Y)位于折流板8(B)附近的情况下，以向折流板8(A)和折流板8(C)双方供给调整水的方式进行控制。
如上所述，本实施方式的洗衣机1具备：脱水桶2，底部2c配置有波轮4，内周面2a1形成有多个通水孔2t；三个以上的折流板8，在周向上等间隔地配置 于脱水桶2的内周面2a1；以及注水装置30，能向各折流板8独立地注入调整水，在折流板8的内部形成有从其外周侧壁向径向内侧突出的接水板85，折流板8具有：蓄水空间8Ta，配置于比接水板85靠上方处，蓄留调整水；以及排水空间8Tb，配置于比接水板85靠下方处，将从蓄水空间8Ta流出的调整水排水，蓄水空间8Ta的周向长度形成为比排水空间8Tb的周向长度长，蓄水空间8Ta的内周面具有以越是趋向下方越配置于径向外侧的方式倾斜的倾斜面A，并且在脱水桶2中排水空间8Tb的周向两侧区域配置有通水孔2t。
当采用这样的结构时，由于蓄水空间8Ta的内周面具有以越是趋向下方越配置于径向外侧的方式倾斜的倾斜面A，因此即使在使折流板8在周向上变宽的情况下，在脱水时从脱水桶2内的洗涤物中脱水出的水也会被引导向脱水桶2的下方。这样一来，由于在蓄水空间8Ta的下方配置有通水孔2t，因此高效地将从洗涤物中脱水出的水向脱水桶2的外部排出。由此，能在脱水时顺畅地进行脱水。而且，从洗涤物中脱水出的水会从脱水桶2的下部被集中排出，因此，排出的水难以蓄留于外桶3与脱水桶2之间，能将排出的水顺畅地导向外桶3的排水孔。
在这样的本实施方式的洗衣机1中，形成于脱水桶2中排水空间8Tb的周向两侧区域的通水孔2t的开口面积从上方往下方逐渐变小。
当采用这样的结构时，由于形成于脱水桶2中排水空间8Tb的周向两侧区域的通水孔2t的开口面积从上方往下方变小，因此能在脱水时更顺畅地排水。
(第二实施方式)
本实施方式的立式洗衣机与第一实施方式的立式洗衣机不同的点在于折流板8的内周面的形状。对本实施方式的立式洗衣机的结构中与第一实施方式的立式洗衣机相同的部分省略其详细说明。
图7的(a)是从内周侧观察第二实施方式的形成于洗衣机的脱水桶2的内周面2a1的折流板8的图，图7的(b)是图7的(a)的a 1－a 1线处的剖视图，图7的(c)是图7的(a)的a 2－a 2线处的剖视图，图7的(d)是图7的(a)的a 3－a 3线处的剖视图。
如图7的(b)和图7的(c)所示，蓄水空间8Ta的内周面形成为以越是 从上端趋向下端越配置于径向外侧的方式倾斜的倾斜面A。此外，如图7的(a)和图7的(d)所示，在蓄水空间8Ta的内周面的下端部附近形成有向脱水桶2的内侧突出的分流部8Tc。分流部8Tc的沿水平方向的宽度随着从上方趋向下方而变宽。因此，沿着蓄水空间8Ta的内周面从上往下流的水会在分流部8Tc的上端向左右分流，流向排水空间8Tb的周向两侧。
在这样的本实施方式的洗衣机中，在蓄水空间8Ta的内周面的下端部附近形成有使水流向排水空间8Tb的周向两侧分流的分流部8Tc。
当采用这样的结构时，由于在蓄水空间8Ta的内周面的下端部附近形成有使水流向排水空间8Tb的周向两侧分流的分流部8Tc，因此能将从洗涤物中脱水出的水引导向配置于蓄水空间8Ta的下方的通水孔2t，能更顺畅地排水。
(第三实施方式)
本实施方式的立式洗衣机与第一实施方式的立式洗衣机不同的点在于形成有脱水桶2的内周面2a1与折流板8之间的间隙这一点。对本实施方式的立式洗衣机的结构中与第一实施方式的立式洗衣机相同的部分省略其详细说明。
图8的(a)是从内周侧观察第三实施方式的形成于洗衣机的脱水桶2的内周面2a1的折流板8的图，图8的(b)是脱水桶2的示意图。
蓄水空间8Ta的内周面形成为以越是从上端趋向下端越配置于径向外侧的方式倾斜的倾斜面A。如图8的(b)所示，在脱水桶2的内周面2a1与折流板8的背面(折流板8的径向外侧的面)之间形成有间隙。因此，在脱水时从脱水桶2内的洗涤物中脱水出的水能通过脱水桶2的内周面2a1与折流板8的背面之间的间隙。
如图8的(a)和图8的(b)所示，在脱水桶2的内周面2a1中，在与折流板8的背面对置的部分配置有多个通水孔2t。如此，在本实施方式中，在脱水桶2的内周面2a1中被折流板8的蓄水空间8Ta遮住的部分配置有多个通水孔2t。因此，在脱水时从脱水桶2内的洗涤物中脱水出的水会从折流板8的蓄水空间8Ta的左右两端部绕到背面侧，通过脱水桶2的内周面2a1与折流板8的背面之间的间隙后从通水孔2t向脱水桶2的外部排出。
在这样的本实施方式的洗衣机中，在脱水桶2的内周面2a1与折流板8的 背面之间形成有间隙，并且在脱水桶2的内周面2a1中与折流板8的背面对置的部分配置有通水孔2t。
当采用这样的结构时，在脱水时从脱水桶2内的洗涤物中脱水出的水会从折流板8的左右两端部绕到背面侧，通过脱水桶2的内周面2a1与折流板8的背面之间的间隙从通水孔2t向脱水桶2的外部被高效地排出。
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的方式，可以进行各种变形。
例如，在上述第一～第三实施方式中，蓄水空间8Ta的内周面的整个区域都是以越是趋向下方越配置于径向外侧的方式倾斜的倾斜面A，但也可以是，只有蓄水空间8Ta的内周面的局部是以越是趋向下方越配置于径向外侧的方式倾斜的倾斜面A。
在上述第一～第三实施方式中，形成于脱水桶2中排水空间8Tb的周向两侧区域的通水孔2t的开口率从上方往下方变小，但不限定于此。例如，也可以是，形成于脱水桶2中排水空间8Tb的周向两侧区域的通水孔2t的开口率在其整个区域中固定。在上述第一～第三实施方式中，形成于脱水桶2的内周面的通水孔2t的开口面积、数量、配置是任意的。
在上述第一～第三实施方式中，设有三个折流板8，具备具有用于向三个折流板8注水的三个导水槽5a、5b、5c的接水环单元5，但并不限定于此，只要是设有三个以上折流板8并具备能向各折流板8独立地注入调整水的注水装置的结构即可。
