Description

洗衣机 技术领域
本发明涉及一种能够从洗衣机主体的外侧确认脱水桶的外表面被清洗的情况的洗衣机。
背景技术
将脱水桶旋转自如地容纳于外桶内的洗衣机一般是向脱水桶内投入洗涤物以及洗涤剂以开始洗涤的洗衣机，供给至脱水桶内的水介由形成于脱水桶的许多通水孔向外桶流出。因此，洗涤时脱水桶的外表面处于浸泡于洗涤水、漂洗水的状态，脱水后，附着于洗涤物的污垢、一部分洗涤剂残渣也残留堆积于脱水桶的外表面，以此作为营养源，在脱水桶的外表面产生霉菌(主要是黑霉)。
在一般的洗衣机中，如果不从洗衣机主体卸下脱水桶，就无法确认这种脱水桶的外表面的状态，但脱水桶连接于作为旋转驱动机构的电机，使用者无法容易地进行拆卸。
因此，一般将桶清洗用的除霉剂投入洗衣机，并通过例如桶清洗模式来进行洗涤运转，通过化学方法来实现脱水桶的外表面的污垢、霉菌的去除。但是，考虑到由除霉剂所引发的水质污染、经济性、污垢的去除效率等，可以说相比于通过除霉剂实现的化学方法，机械方法更优越。
因此，作为脱水桶清洗的机械方法，专利文献1中公开了具备用于对脱水桶的外表面进行清洗的刷子的洗衣机。专利文献1所公开的洗衣机在俯视时为矩形的外桶的内部配置有俯视时为圆形的脱水桶，在构成死角的外桶的角落，具备能够抵接于脱水桶的外表面的刷子。

发明所要解决的问题
但是，专利文献1所公开的洗衣机，如果不对洗衣机进行拆卸从而将脱水桶从洗衣机主体卸下，就无法确认脱水桶的外表面的状态，因此存在的问题是： 无法轻易地确认脱水桶的污浊情况，难以确定需要对脱水桶进行清洗的时期。此外，存在不能直接观察通过刷子进行的桶清洗处理的情况，不能轻易地确认桶清洗处理的效果这样的不便。
发明内容
本发明的目的在于有效地解决这样的问题，具体而言，其目的在于提供一种不用进行洗衣机的拆卸就能观察脱水桶的外表面的状态，能够容易地确定需要进行桶清洗的时期，并且能够观察桶清洗处理的情况，容易地确认桶清洗处理的效果的洗衣机。
用于解决课题的方法
本发明为了达成相关目的，采取了如下方案。
即，本发明的洗衣机的特征在于，具备：洗衣机主体，在侧板形成有窗部；外桶，配置于所述洗衣机主体的内部，并且至少对应于所述窗部的部分具有由透明构件构成的透明区域；脱水桶，旋转自如地配置于所述外桶的内部；电机，旋转驱动所述脱水桶；以及桶清洗单元，配置于所述外桶与所述脱水桶之间且配置于与所述窗部以及所述透明区域对应的位置，能够抵接于所述脱水桶的外表面。

进而，本发明优选采用的结构是：所述抵接/分离单元具备转矩电机，通过该转矩电机赋予使所述桶清洗单元转动的驱动力。
特别地，本发明优选采用的结构是：所述桶清洗单元具有连接所述刷部与所述支承轴部的连接部，所述连接部在其内部形成有水路，该水路具有：主流部，从始端向末端直径一步步缩小，并且沿着与所述脱水桶的旋转轴平行的方向延伸；以及喷射部，从该主流部向所述刷部开口，并形成于沿着与所述脱水桶的旋转轴平行的方向的多个位置，所述洗衣机具备：供水单元，能够从所述 始端向所述主流部供给水。

此外，根据具备所述抵接/分离单元的本发明，通过抵接/分离单元使桶清洗单元在抵接位置与分离位置之间绕着支承轴部转动，由此，在洗衣机主体的内部用于容纳桶清洗单元的空间很小即可，能够抑制由装配桶清洗单元所引起的洗衣机的大型化。
进而，根据所述抵接/分离单元具备转矩电机的本发明，与抵接/分离单元具备例如步进电机的情况相比，能够使桶清洗处理的控制变得容易。
特别地，根据在所述桶清洗单元的所述连接部的内部形成有具有主流部和喷射部的水路的本发明，通过从供水单元向连接部内部的水路供给水，能够以大致均匀的压力使水从连接部喷射，因此在桶清洗处理时，无需在外桶内蓄水，利用很少的水量就能够进行桶清洗处理，并且在利用从喷射部喷射的水进行桶清洗的同时也能够清洗刷部。
此外，根据所述桶清洗单元能够从所述外桶与所述脱水桶之间拆装的本发明，能够进行桶清洗单元的维护。
进而，根据所述脱水桶的至少一部分由透明构件构成的本发明，不仅脱水桶被清洗的情况，衣物等在脱水桶内被洗涤的情况也能够介由窗部、透明区域以及脱水桶，从洗衣机主体的外侧进行确认。

具体实施方式
以下，参照附图对本发明的实施方式加以说明。
图1是表示本发明的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的大致结构的纵剖视图。图3是表示外桶3以及其周边的结构的立体图。
洗衣机1具备洗衣机主体2、外桶3、脱水桶4、驱动装置6、桶清洗组件7U、供水单元9(参照图3)和后述的作为控制单元的控制部。
洗衣机主体2为大致长方体形状，且配置成：在上表面20具有用于将作为洗涤物的衣物投入取出脱水桶4的开口21和能够开闭该开口21的上盖22，能够通过打开上盖22，介由开口21将衣物投入取出脱水桶4。在洗衣机主体2的上表面20还具备由具有运转开始按钮、后述的桶清洗模式按钮等的控制板23a构成的输入部23。控制板23a构成为能够从洗衣机主体2卸下(参照图7)。此外，在作为洗衣机主体2的侧板的前板2a，形成有嵌入了透明构件的大致矩形的窗部24。作为透明构件，可以使用聚对苯二甲酸乙二醇酯(PET)、聚萘二甲酸乙二醇酯(PEN)、聚碳酸酯(PC)等。
如图3所示，外桶3配置于洗衣机主体2的内部，是能够蓄水的大致有底筒状的构件，具有外桶主体30和能够容纳桶清洗组件7U的容纳部31。
外桶主体30为有底筒状，沿着与脱水桶4的旋转轴S平行的方向，侧面30b以及上表面30a的一部分被切出缺口。
容纳部31从这样的侧面30b的缺口端30a1朝向外桶主体30的径向外方，以俯视时呈大致矩形的方式突出。此外，容纳部31以能够装配后述的桶清洗组件7U所具备的转矩电机80的方式，在上端部形成有缺口部分31a。此外，沿着外桶主体30的上表面30a配置有对后述的桶清洗组件7U的桶清洗装置进行供 水的供水管9a。供水管9a的一端部90位于用于向外桶3内供给水的供水口92的附近，另一端91位于与桶清洗组件7U的连接部分。供水管9a与后述的桶清洗供水阀27一起构成供水单元9。
在本实施方式中，外桶3几乎整体由透明构件构成，在与洗衣机主体2的窗部对应的部分形成透明区域32。需要说明的是，与窗部24对应的部分是指能够从洗衣机主体2的外侧介由窗部24观察到的部分。图3示出从容纳部31透视的桶清洗组件7U，省略了从外桶主体30透视的脱水桶4等的图示。这在图1和图4中也是一样。作为透明构件，可以使用聚对苯二甲酸乙二醇酯(PET)、聚萘二甲酸乙二醇酯(PEN)、聚碳酸酯(PC)等。
脱水桶4是在外桶3的内部，与外桶3同轴地旋转自如地配置的有底筒状的构件。脱水桶4比外桶3直径小，其壁面具有许多通水孔3a，在脱水时，使水通过通水孔3a从设于外桶3的排水口(未图示)流出。作为脱水桶4，为了确保后述的桶清洗单元7的容纳空间，可以使用相对于外桶3的尺寸比通常的洗衣机中所采用的尺寸小一圈的脱水桶。此外，作为洗衣机主体2(外壳)以及外桶3，也可以采用如下结构：通过使用相对于脱水桶4的尺寸比通常的洗衣机中所采用的尺寸大一圈的构造，确保桶清洗单元7的容纳空间。
如图2所示，在脱水桶4的底部41中央，旋转自如地配置有波轮(搅拌翼)5。波轮5对蓄积于外桶3的水进行搅拌从而产生水流。
驱动单元6包括电机61和离合器62，电机61使脱水桶4以及波轮5旋转，赋予用于使容纳于脱水桶4的洗涤物旋转的驱动力。
具体而言，通过电机61使向脱水桶4的底部41伸出的驱动轴63旋转，从而脱水桶4旋转。此外，由电机61产生的旋转力通过切换离合器62还将驱动力赋予波轮5，从而使波轮5旋转。因此，洗衣机1能够在洗涤衣物等时主要是仅使波轮5旋转，在脱水时使脱水桶4和波轮5一体地高速旋转。
在配置于如上所述的外桶3与脱水桶4之间且配置于与窗部24以及透明区域32对应的位置即外桶3的容纳部31的桶清洗组件7U如图3所示具有桶清洗单元7、抵接/分离单元8和隔离单元75。隔离单元75在一面侧配置有桶清洗单元7，在另一面侧配置有抵接/分离单元8的转矩电机80，具有大致矩形板状的基板部77和从基板部77向外桶3的径向外方突出的突出部76。
桶清洗单元7将在后面详述，其能够与脱水桶4的如图2所示的外表面40 抵接。因此，在桶清洗单元7与脱水桶4的外表面40抵接的状态下，电机61使脱水桶4旋转，能够通过桶清洗单元7摩擦清洗脱水桶4的外表面40，并且介由洗衣机主体2的窗部24以及外桶3的透明区域32，能够从洗衣机主体2的外侧确认图1中用双点划线示出的桶清洗处理中的桶清洗单元7和脱水桶4的外表面40。因此，不用进行洗衣机1的拆卸就能够观察到脱水桶4的外表面40的状态，并且容易地确定需要进行桶清洗的时期，并且能够观察桶清洗处理的情况，容易地确认桶清洗处理的效果。
使用图4和图5，具体地描述桶清洗单元7的构造。图4是从外桶3的内侧观察桶清洗单元7的图。图5是示意地表示桶清洗单元7的纵剖视图。图6是用于说明桶清洗单元7的位移的图。如图4所示，桶清洗单元7具有支承轴部70、刷部71和连接部72。
支承轴部70在隔离装置75的突出部76所形成的容纳空间S内穿过形成于突出部76的上表面76a的贯通孔76b，并且在与脱水桶4的旋转轴S平行的方向即上下方向上延伸。
刷部71相对于支承轴部70，在与旋转轴S正交的方向即水平方向上分离地配置，并且在上下方向上延伸地形成。
连接部72连接支承轴部70与刷部71，具有从自支承轴部70沿着上下方向的多个位置(本实施方式中有4处)水平延伸的水平部分72a和连接于水平部分72a，并且在与脱水桶4对置的面上形成有刷部71的支承部分72b。刷部71由铆接固定于支承部分72b的多个毛状构件(例如尼龙制)构成。此外，在这样的水平部分72a之间形成有开口部72a2，介由该开口部72a2能够从洗衣机主体2的外侧确认刷部71。
此外，如图5所示，连接部72的支承部分72b在其内部形成水路78，该水路78具有从始端78a1向末端78a2直径φ1～φ3一步步缩小，并且沿着与脱水桶4的旋转轴S(参照图3)平行的方向延伸的主流部78a和从该主流部78a朝向刷部71开口并形成于沿着与脱水桶4的旋转轴S(参照图3)平行的方向的多个位置的喷射部78b。在主流部78a的中途，彼此分离地配置有多个节流孔板79，介由节流孔板79一步步直径一步步缩小。该水路78从主流部78a的始端78a1穿过水平部分72a(参照图4)延伸至支承轴部70，连接于所述供水管9a(参照图3)的另一端91。通过供水管9a进行供给的水从始端78a1供给至主流 部78a，此水通过喷射部78b被喷射。
因此，在桶清洗处理中，通过从供水单元9向具备节流孔板79的水路78供给水，能够从连接部72的上端部遍及下端部地以大致均匀(均等)的压力喷射水。因此，在清洗脱水桶4的外表面40时，与在外桶3蓄有水的状态下进行桶清洗处理的情况相比，能够节水并且通过从喷射部78b喷射出的水来清洗刷部71。
返回图3，抵接/分离单元8具有配置于桶清洗单元7的支承轴部70的上端部的螺旋弹簧构件(弹簧)80d、配置于基板部77的上端部的转矩电机80、一端侧80b1连接(缠绕)于转矩电机80的旋转部80a的线构件80b和基端部80c1固定于支承轴部70的转动构件80c。转矩电机80配置于基板部77的上端部且另一面侧，由此能够防止转矩电机80沾水。
螺旋弹簧构件80d的一端80d1抵接于隔离单元75的基板部77的一面侧，并且图4所示的另一端侧80d2固定于在桶清洗单元7的连接部72形成的固定槽72a1。螺旋弹簧构件80d能够通过其弹力将连接部72按压向隔离单元75的基板部77。
在图3所示的转动构件80c，固定有线构件80b的另一端80b2，当转矩电机80驱动并且卷起线构件80b时，转动构件80c以基端部80c1为基点向转矩电机80侧转动。由于转动构件80c的基端部80c1固定于桶清洗单元7的支承轴部70，因此，伴随着转动构件80c的转动，支承轴部70也会抵抗螺旋弹簧构件80d的弹力进行转动。由此，如图6所示，桶清洗单元7从刷部71离开脱水桶4的外表面40的分离状态，以规定角度(20°～60°左右)绕着支承轴部70转动，如图3中的双点划线所示，在刷部71的顶端部71a抵接于脱水桶4的外表面40的抵接状态下发生位移。当转矩电机80的驱动停止时，处于抵接状态的桶清洗单元7通过螺旋弹簧构件80d的弹力而变成分离状态。
在此，当假设使桶清洗单元7一直处于抵接状态时，由于在通常的洗涤运转时会对电机61施加负荷，因此除桶清洗处理以外，优选使桶清洗单元7处于分离状态，并且优选以能够在洗衣机1内发生位移的方式容纳桶清洗单元7。因此，如上所述，采用通过抵接/分离单元8在抵接位置与分离位置之间使桶清洗单元7绕着支承轴部70转动的结构，由此，在洗衣机主体2的内部用于容纳桶清洗单元7的空间很小即可，能够抑制由装配桶清洗单元7所引起的洗衣机1 的大型化。
此外，通过转矩电机80赋予使桶清洗单元7转动的驱动力，由此，与例如使用步进电机的情况相比，微机控制变得简单。而且，不同于使用步进电机的情况，不必担心桶清洗单元7由于脱水桶4的旋转而被推压造成错位，因此，不需要桶清洗单元7的位置感测单元。采用通过这样的转矩电机80和上述螺旋弹簧构件80d使桶清洗单元7转动的结构，从而能够通过转矩电机80的电源的通/断和简单的微机控制，执行用于桶清洗处理的程序，能够降低成本、削减开发工时。
图7是在卸下桶清洗组件7U的状态下表示洗衣机1的立体图。如图7所述，如上的桶清洗组件7U构成为能够相对于洗衣机主体2，介由通过将控制面板23a从洗衣机主体2卸下而显现的插入口23b进行拆装，并且构成为能够进行桶清洗单元7的维护。因此，在洗衣机主体2设有用于装配桶清洗组件7U的未图示的连接器。此外，在拆卸时，将供水管9a的另一端91(参照图3)从支承轴70卸下。
图8是表示本实施方式的洗衣机1的电结构的框图。该洗衣机1的动作通过包括微型计算机的控制部95来进行控制。控制部95具备ROM71以及RAM72，通过微型计算机来执行存储于该ROM71的程序，从而进行预先设定的运转动作。在RAM72临时存储有执行上述程序时所使用的数据等。
对于控制部95，除所述电机61以及离合器62以外，连接有作为控制对象的用于向外桶3供给水的供水阀24以及用于将外桶3内的水排出的排水阀25、桶清洗供水阀27等。需要说明的是，在上述图2等中省略供水阀24、排水阀25以及桶清洗供水阀27的图示。
此外，对于控制部95，除上述的输入部23以外，输入来自计时器28、水位传感器29、簧开关SW26等的信号。簧开关SW26用于判断桶清洗单元7的刷部71是否已与脱水桶4的外表面40接触。
使用图9来说明本实施方式的洗衣机1所进行的桶清洗处理。图9是表示桶清洗处理的流程的流程图。
<步骤SP1>
在步骤SP1中，控制部95判断输入部23所具有的桶清洗模式按钮是否被按下，输入了进行桶清洗的指示。
<步骤SP2>
在步骤SP2中，控制部95等到输入桶清洗的指示，判断上盖22是否为关闭状态。当判断为非关闭状态时，进入步骤SP3(步骤SP2：否)，当判断为非关闭状态时，进入步骤SP4(步骤SP2：是)。
<步骤SP3>
在步骤SP3中，控制部95使输入部23显示表示上盖22为打开状态的错误。
<步骤SP4>
在步骤SP4中，控制部95等到判断上盖22为关闭状态，使排水阀25打开。。
<步骤SP5>
在步骤SP5中，控制部95使桶清洗供水阀27打开。
<步骤SP6>
在步骤SP6中，控制部95使转矩电机80运转，使桶清洗单元7相对于脱水桶4的外表面40处于如图6中双点划线所示的抵接状态。
<步骤SP7>
在步骤SP7中，控制部95判断簧开关SW26是否已变成打开，由此来判断桶清洗单元7是否已转动而使得电刷部71与脱水桶4的外表面40抵接。
<步骤SP8>
在步骤SP8中，控制部95等到簧开关SW26变为打开，向电机61输入信号，使脱水桶4旋转。需要说明的是，此时的脱水桶4的旋转速度比脱水时的脱水桶4的旋转速度小。
由此，水介由桶清洗单元7的进水路78被喷射，脱水桶4的外表面40被刷部71的顶端部71a摩擦，从而脱水桶4的外表面40的污垢、霉菌通过机械力被洗掉。
<步骤SP9>
在步骤SP9中，控制部95判断计时器28是否已到规定时间，由此来判断是否已达到预先设定的桶清洗时间。
<步骤SP10>
在步骤SP10中，控制部95等到计时器28达到规定时间，向电机61输入信号，使脱水桶4的旋转停止。
<步骤SP11>
在步骤SP11中，控制部95使转矩电机80停止，使桶清洗单元7相对于脱水桶4呈分离状态。
<步骤SP12>
在步骤SP12中，控制部95使桶清洗供水阀27关闭。
<步骤SP13>
在步骤SP13中，控制部95使排水阀25关闭。由此，桶清洗处理结束。
这样的桶清洗处理可以设定成使用者介由洗衣机主体2的窗部24来确认脱水桶4的外表面40的状态，并在任意的定时进行，或者也可以设定成在指定循环次数运转后使设于输入部23的显示灯显示(搭载时间戳功能)，并在使用者确认了显示灯的显示的时刻进行。通过搭载时间戳功能，脱水桶4的外表面40更不易在污浊的状态下被置之不理。
接着，使用图10来说明例如为了进行维护而对桶清洗单元7U进行拆装的流程。图10是表示更换桶清洗单元7的流程的流程图。图10(a)是表示取出桶清洗组件7U的流程的流程图。
<步骤SP21>
在步骤SP21中，切断洗衣机的电源。
<步骤SP22>
在步骤SP22中，如图7所示，将控制板23a从洗衣机主体2卸下。
<步骤SP23>
在步骤SP23中，将桶清洗组件7U向上方取出。
<步骤SP24>
在步骤SP24中，将控制板23a装配于洗衣机主体2回到原位。
接着，图10(b)是表示装配桶清洗组件7U的流程的流程图。
<步骤SP31>
在步骤SP31中，如图7所示，将控制板23a从洗衣机主体2卸下。
<步骤SP32>
在步骤SP32中，将桶清洗组件7U从上方装配于洗衣机主体2。
<步骤SP33>
在步骤SP33中，将控制板23a装配于洗衣机主体2。
需要说明的是，各部分的具体方案并不只限于上述的实施方式。
例如，在本实施方式中，桶清洗单元7作为桶清洗组件7U能够从洗衣机主体2拆装，也可以采用如图11所示的洗衣机1A那样，桶清洗单元7不能从洗衣机主体2拆装的结构。图11是表示变形例的洗衣机1A的立体图。在图11中示出洗衣机1A的外桶3以及其附近。
具体而言，外桶3的收纳部31A的上部不开放，而是与外桶主体30A一体地构成，转矩电机80装配于这样的外桶3的上端部。此外，不设置如图3所示的隔离单元75，而是在收纳部31A的上表面31A1形成有连通供水管9a和桶清洗单元7的支承轴部70的未图示的贯通孔。该贯通孔是用于对配置于外桶3内侧的桶清洗单元7传递配置于外桶3的外表面的转矩电机80的驱动力所必需的，通过在外桶3的上部形成这样的贯通孔，从而能够减少从外桶3介由贯通孔漏水的风险。
而且，这样的收纳部31A的前板31A2，即仅与洗衣机主体2的窗部24(参照图1)对应的部分由透明构件构成，通过该透明构件形成透视桶清洗单元7以及脱水桶4的外表面40的透明区域32A。透明区域32A是在开口于收纳部31A的前板31A2的开口窗31A3嵌入透明构件而构成的区域。
此外，在本实施方式中，脱水桶4由不透明的构件构成，单页可以采用脱水桶4的至少一部分由透明构件构成的结构。作为透明构件，可以使用聚对苯二甲酸乙二醇酯(PET)、聚萘二甲酸乙二醇酯(PEN)、聚碳酸酯(PC)等。
由此，不仅是脱水桶4的外表面40和桶清洗单元7，洗涤物在脱水桶4内被洗涤的情况也能够介由窗部24、透明区域32以及脱水桶4从洗衣机主体2的外侧进行确认，并且能够进行洗涤时的水位调整以及漂洗的确认。
此外，在采用脱水桶4形成有窗部、窗部嵌入有透明构件的结构的情况下，使用簧开关SW、霍尔IC等，以暂时停止、洗涤结束时的脱水桶4的窗部的位置始终对应于洗衣机主体2的窗部24的方式进行控制。
此外，在上述实施方式中，刷部71由多个毛状构件构成，但只要是抵接于脱水桶4的外表面40从而能够去除污垢的结构，则不限于毛状构件，也可以是海绵材料、纤维构件等其他构件。
此外，在本实施方式中，抵接/分离单元8是具备转矩电机80的结构，但也可以是具备例如步进电机等其他电机的结构。
而且，桶清洗单元7不限于从内部喷射水的结构，也可以是在外桶3蓄有 水的状态下进行桶清洗处理的结构。此外，桶清洗单元7也可以是不进行转动的结构。
此外，在本实施方式中，窗部24形成于洗衣机主体2的前板2a，但不限于前板2a，也可以形成于横板，还可以形成于前板2a以及横板双方。而且，窗部24的形状也不限于大致矩形，也可以是椭圆形。
而且，在本实施方式中，桶清洗单元7适用于立式的洗衣机1，但这样的桶清洗单元7也适用于滚筒式的洗衣机。
其他结构也可以在不超出本发明的技术精神的范围内进行各种变形。
