Abstract

本发明提供一种能以不使洗涤物劣化的方式进行洗涤的洗衣机。洗衣机(1)包括：滚筒(7)，收容洗涤物(L)；以及控制部(20)。控制部(20)执行通过养护剂来护理滚筒(7)内的洗涤物(L)的纤维的护理过程和在护理过程之后洗涤滚筒(7)内的洗涤物(L)的洗涤过程。

Description

洗衣机 技术领域
本发明涉及一种洗衣机。
背景技术
下述专利文献1所述的滚筒式洗干一体机包括收容洗涤物的滚筒和使滚筒旋转的马达。在滚筒式洗干一体机的清洗过程和漂洗过程中，通过使蓄有水的滚筒旋转，洗涤物被反复进行提升一定程度之后向水面自然落下的“翻滚”。
洗涤物一般通过编织许多图1所示的纤维S而构成。不限于专利文献1的滚筒式洗干一体机，普通的洗衣机都会有因洗涤过程中纤维S彼此直接接触而导致洗涤物发硬的隐患。
此外，在纤维S为羊毛等兽毛的情况下，纤维S的表面被许多角质层K覆盖。如图1中由双点划线包围的部分的放大图即图2所示，各个角质层K为鳞片状，这些角质层K通常为整齐的状态，因此纤维S的表面平滑。但是，如图3所示，当在用洗衣机进行的洗涤过程中纤维S被润湿时，会因各个角质层K散开紊乱而导致纤维S的表面变为堆砌的状态(粗糙状态)。于是，会有因纤维S彼此牵扯缠绕而导致洗涤物收缩的隐患。
在使用者期望洗涤物不会因发硬、收缩而劣化，一直保持新品的手感的情况下，只要将每次洗涤委托给洗衣公司即可，但将洗涤物带到洗衣公司的工夫和费用成为负担。因此，期望能以不使洗涤物劣化的方式用自家的洗衣机进行洗涤。

发明内容
发明所要解决的问题
本发明是基于这样的背景而完成的，其目的在于提供一种能以不使洗涤物劣化的方式进行洗涤的洗衣机。

本发明是一种洗衣机，包括：洗涤筒，收容洗涤物；以及控制部，执行通过养护剂来护理所述洗涤筒内的洗涤物的纤维的护理过程和在所述护理过程之后洗涤所述洗涤筒内的洗涤物的洗涤过程。
此外，本发明的特征在于，所述洗衣机还包括产生转矩的驱动部，所述洗涤筒为接受所述驱动部的转矩来进行旋转的滚筒，所述控制部在所述护理过程之前的准备过程中通过所述驱动部来使收容有干燥状态的洗涤物的所述滚筒旋转。
此外，本发明的特征在于，所述洗衣机还包括用于向所述滚筒内供水的供水部，所述控制部在所述护理过程中执行：供水处理，通过所述供水部来向所述滚筒内供水，将溶解有所述养护剂的水即养护水蓄于所述滚筒内；预浸泡处理，在所述供水处理之后，在静止状态的所述滚筒内将洗涤物浸入所述养护水中；旋转处理，在所述预浸泡处理之后，通过所述驱动部来使蓄有所述养护水的状态的所述滚筒旋转；以及摆动处理，在所述旋转处理之后，通过所述驱动部来使蓄有所述养护水的状态的所述滚筒摆动。

发明效果
根据本发明，在洗衣机中，洗涤筒内的洗涤物在护理过程中通过养护剂对纤维进行护理之后在洗涤过程中被洗涤。由养护剂进行了护理的纤维处于纤维 表面被涂覆了养护剂的状态。因此，在洗涤过程中，纤维彼此不直接接触，因此能抑制由纤维彼此的摩擦引起的洗涤物的发硬。此外，纤维中被涂覆了养护剂的表面维持角质层整齐的平滑状态，因此在洗涤过程中纤维彼此不易缠绕，因此能抑制洗涤物的收缩。由此，能以不使洗涤物劣化的方式进行洗涤。
此外，根据本发明，在洗涤筒为滚筒的洗衣机中，在护理过程之前的准备过程中，收容有干燥状态的洗涤物的滚筒旋转，因此能事先将堵在洗涤物深处的灰尘等异物敲出。由此，在此后的护理过程中，通过使涂剂遍及至去除了异物的洗涤物的纤维的细微部分，能充分地护理纤维。
此外，根据本发明，在洗衣机的护理过程中，依次执行供水处理、预浸泡处理、旋转处理以及摆动处理。在供水处理中，作为溶解有养护剂的水的养护水蓄于滚筒内。在此后的预浸泡处理中，通过在静止状态的滚筒内将洗涤物浸泡在养护水中，能通过养护剂来将洗涤物的纤维仔细涂敷。在旋转处理中，通过使蓄有养护水的状态的滚筒旋转，能改变洗涤物中与养护水接触的区域。由此，能使养护水浸透至整个洗涤物的深处而通过养护剂来有效地涂敷许多纤维。在摆动处理中，通过时蓄有养护水的状态的滚筒摆动来使洗涤物轻柔地摆动，此时，能通过养护剂来更有效地涂敷整个洗涤物中的纤维。因此，能进一步抑制洗涤物的发硬、收缩。
此外，根据本发明，通过反复执行预浸泡处理、旋转处理以及摆动处理，能通过养护剂来将洗涤物的所有纤维无遗漏地涂敷。
此外，根据本发明，作为养护剂可以使用柔顺剂。此外，在洗衣机中，在供水处理中通过投入部来向滚筒内自动投入柔顺剂，因此能自动生成养护水并将其蓄于滚筒内。

具体实施方式
以下，参照附图对本发明的实施方式进行具体的说明。图4是本发明的一实施方式的洗衣机1的示意性纵剖右视图。将与图4的纸面正交的方向称为洗衣机1的左右方向X，将图4中的左右方向称为洗衣机1的前后方向Y，将图4中的上下方向称为洗衣机1的上下方向Z。
左右方向X当中，将图4的纸面的里侧称为左侧X1，将图4的纸面的表侧称为右侧X2。前后方向Y当中，将图4中的左侧称为前侧Y1，将图4中的右侧称为后侧Y2。上下方向Z当中，将上侧称为上侧Z1，将下侧称为下侧Z2。左右方向X和前后方向Y包含在横向中。横向既可以是水平方向H，也可以是相对于水平方向H稍微倾斜的大致水平方向。
洗衣机1也包括立式全自动洗衣机、双桶式洗衣机，但以下以滚筒式洗衣机为例对洗衣机1进行说明。洗衣机1包括：箱体2、配置在箱体2内的水筒3、 与水筒3连接的供水路4和排水路5以及用于向水筒3内投入洗涤剂、柔顺剂等的投入部6。洗衣机1还包括作为收容于水筒3内并收容洗涤物L的洗涤筒的一个例子的滚筒7和作为使滚筒7旋转的驱动部的一个例子的马达8。洗衣机1也可以具有将滚筒7内的洗涤物L烘干的烘干功能，在该情况下，包括用于向滚筒7内供给热风的结构(未图示)。
箱体2形成为箱状。箱体2的前表面2A例如是垂直面。在前表面2A形成有使箱体2内外连通的开口2B。在前表面2A设有将开口2B开闭的门9。在以下的说明中，以门9关闭开口2B的状态为基准。
水筒3由从箱体2的底壁2C向上侧Z1延伸的减振器10支承，并由弹簧(未图示)悬挂。由此，水筒3及其内侧的滚筒7整体由箱体2弹性支承。水筒3具有：圆筒状的圆周壁3A，以沿水平方向H向前后方向Y延伸的轴线J为中心；圆盘状的背面壁3B，从后侧Y2堵住圆周壁3A的中空部分；以及环状的正面壁3C，与圆周壁3A的前端缘相连。
背面壁3B沿着上下方向Z垂直配置。在背面壁3B的中心形成有沿轴线J在前后方向Y上贯通背面壁3B的贯通孔3D。正面壁3C具有：圆环状的第一部3E，从圆周壁3A的前端缘向轴线J侧突出；圆筒状的第二部3F，从第一部3E的内周缘向前侧Y1突出；以及圆环状的第三部3G，从第二部3F的前端缘向轴线J侧突出。在第三部3G的内侧形成有从前侧Y1与圆周壁3A的中空部分连通的出入口3H。出入口3H处于从后侧Y2与箱体2的开口2B连通的状态。
供水路4具有与水龙头(未图示)连接的一端4A和与水筒3的正面壁3C的第二部3F的例如上部连接的另一端4B。排水路5与水筒3的下端部、例如圆周壁3A的下端部连接。
洗衣机1包括设于供水路4的可开闭的供水阀11和设于排水路5上的可开闭的排水阀12。开状态的供水阀11处于打开了供水路4的接通状态，闭状态的供水阀11处于关闭了供水路4的断开状态。开状态的排水阀12处于打开了排水路5的接通状态，闭状态的排水阀12处于关闭了排水路5的断开状态。
当供水阀11在排水阀12关闭的状态下打开时，来自水龙头的自来水流过供水路4。以下，自来水有时简称为“水”。流过供水路4的水从供水路4的另 一端4B流入水筒3内而蓄留。当排水阀12在水筒3中蓄有水的状态下打开时，水筒3内的水从排水路5向箱体2之外即机外排出。
投入部6包括洗涤剂投入部6A和柔顺剂投入部6B。洗涤剂投入部6A和柔顺剂投入部6B各自包括：收容洗涤剂或柔顺剂的盒13、从盒13延伸并与供水路4相连的投入路14以及设于投入路14的可开闭的投入阀15。
盒13在箱体2内配置于比水筒3靠上侧Z1的区域。盒13的至少一部分从箱体2的前表面2A或上表面2D露出。盒13中的从前表面2A或上表面2D露出的露出部分可以是可开闭的盖或抽屉。使用者能将该露出部分打开或抽出从而向盒13内补充洗涤剂或柔顺剂。洗涤剂投入部6A的盒13和柔顺剂投入部6B的盒13既可以如图4所示分开存在，也可以一体化。
投入路14从盒13的下部向下侧Z2延伸，与供水路4中的比供水阀11靠另一端4B侧的部分连接。开状态的投入阀15处于打开了投入路14的接通状态，闭状态的投入阀15处于关闭了投入路14的断开状态。
当洗涤剂投入部6A的投入阀15在供水阀11打开的状态下打开时，洗涤剂投入部6A的盒13内的洗涤剂经过投入路14流入供水路4，随着供水路4内的水从另一端4B投入水筒3内。当柔顺剂投入部6B的投入阀15在供水阀11打开的状态下打开时，柔顺剂投入部6B的盒13内的柔顺剂经过投入路14流入供水路4，随着供水路4内的水从另一端4B投入水筒3内。以下，溶解有洗涤剂、柔顺剂的水也与自来水同样地有时简称为“水”。
滚筒7是具有与轴线J一致的中心轴线的圆筒体，比水筒3小一圈。在本实施方式中，滚筒7以中心轴线沿着水平方向H的方式水平配置，但也可以以中心轴线相对于水平方向H倾斜的方式倾斜配置。滚筒7具有：圆筒状的圆周壁7A，与水筒3的圆周壁3A同轴配置；圆盘状的背面壁7B，从后侧Y2堵住圆周壁7A的中空部分；以及圆环状的环状壁7C，从圆周壁7A的前端缘向轴线J侧突出。
在滚筒7中的至少圆周壁7A处形成有多个贯通孔7D，水筒3内的水经由贯通孔7D在水筒3与滚筒7之间往来。因此，水筒3内的水位与滚筒7内的水位一致。如上所述，在开状态下向水筒3内供给水的供水阀11作为用于向滚筒 7内供水的供水部的一个例子发挥功能。
在滚筒7的背面壁7B的中心设有沿轴线J向后侧Y2延伸的支承轴7E。支承轴7E的后端部穿过水筒3的背面壁3B的贯通孔3D而配置于比背面壁3B靠后侧Y2的位置。
在环状壁7C的内侧形成有从前侧Y1与圆周壁7A的中空部分连通的出入口7F。出入口7F处于从后侧Y2与水筒3的出入口3H和箱体2的开口2B对置并连通的状态。出入口3H和出入口7F与开口2B一起由门9统一开闭。使用者经由开放的开口2B、出入口3H以及出入口7F将洗涤物L取出放入于滚筒7内。门9设有垫圈16，该垫圈16在门9关闭了开口2B、出入口3H以及出入口7F时紧贴于水筒3的正面壁3C的第三部3G。
马达8在箱体2内配置于水筒3的背面壁3B的后侧Y2。作为马达8的一个例子，可以采用DD(直驱)马达。马达8与设于滚筒7的支承轴7E连结。马达8所产生的转矩被传递至支承轴7E，因此接受了马达8的转矩的滚筒7伴随支承轴7E绕轴线J旋转。需要说明的是，也可以在马达8与支承轴7E之间设置将马达8的转矩向支承轴7E传递或切断的离合机构(未图示)。
图5是示出洗衣机1的电气结构的框图。洗衣机1还包括显示操作部17、水位传感器18、转速传感器19以及控制部20。
显示操作部17由液晶操作面板等构成，配置于箱体2的前表面2A等(参照图1)。使用者能通过操作显示操作部17来选择洗衣机1中执行的洗涤运转的相关运转条件、模式等或对洗衣机1指示洗涤运转的开始、停止等。显示操作部17中显示有面向使用者的信息。
水位传感器18是检测水筒3内的水位即滚筒7内的水位的传感器。作为水位传感器18，可以采用公知的传感器。
转速传感器19是检测马达8的转速的传感器，例如由霍尔IC构成。在本实施方式中，马达8的转速与滚筒7的转速相同，因此转速传感器19通过检测马达8的转速，实际上检测出滚筒7的转速。需要说明的是，在马达8与滚筒7的支承轴7E之间设有上述的离合机构(未图示)的情况下，滚筒7的转速是将离合机构的减速比等规定的常数乘以马达8的转速而得到的值。转速传感器19 也可以通过检测支承轴7E的转速来直接检测滚筒7的转速。
控制部20例如被配置为包括CPU(中央处理器)、ROM(只读存储器)或RAM(随机存取存储器)等存储器以及计时用的计时器的微型计算机，内置于箱体2内(参照图4)。显示操作部17、水位传感器18、转速传感器19以及上述的马达8、供水阀11、排水阀12和投入阀15各自与控制部20电连接。
使用者对显示操作部17的操作内容被输入控制部20。控制部20控制显示操作部17的显示内容。水位传感器18和转速传感器19各自的检测结果被实时地输入控制部20。控制部20基于从转速传感器19输入的滚筒7的转速，通过控制施加于马达8的电压的占空比来控制马达8使得滚筒7以希望的转速旋转的方式。控制部20控制供水阀11、排水阀12以及投入阀15各自的开闭即接通/断开。
控制部20执行洗涤运转。本实施方式的洗涤运转包括最初阶段的准备过程、准备过程之后的护理过程、护理过程之后的清洗过程、在清洗过程之后一次或多次执行的漂洗过程以及在最后的漂洗过程之后执行的脱水过程。洗衣机1具有烘干功能的情况下的洗涤运转还包括在脱水过程后执行的烘干过程。
参照图6的流程图，开始洗涤运转的控制部20首先使马达8工作，例如以100rpm的低速使滚筒7旋转，基于此时的马达8的电流的电阻值等来检测滚筒7内的洗涤物L的负荷量(步骤S1)。负荷量相当于滚筒7内的洗涤物L的收容量。洗涤物L的收容量的一个例子是洗涤物L的重量，该情况下的单位为kg。
控制部20基于检测出的负荷量，确定洗涤剂和柔顺剂各自的所需量以及护理过程、清洗过程和漂洗过程各自的水筒3内的目标水位来作为洗涤条件(步骤S2)。每负荷量的洗涤剂和柔顺剂各自的所需量以及每负荷量的目标水位被预先确定并存储于控制部20的存储器。
确定了洗涤条件的控制部20执行准备过程(步骤S3)。具体而言，如图7所示，作为护理过程之前的准备过程，控制部20通过在滚筒7中没有水的状态下使马达8工作来使收容有干燥状态的洗涤物L的滚筒7以例如45rpm旋转(步骤S11)。
由此，滚筒7内的洗涤物L(参照图8中实线所示的洗涤物L)在随着滚筒 7的旋转而上升至滚筒7内的最上部时(参照图8中双点划线所示的洗涤物L)，因自重而向正下方落下。由此，收容有干燥状态的洗涤物L的滚筒7旋转，因此能事先将堵在洗涤物L深处的灰尘等异物敲出。如此，准备过程为异物去除过程。
然后，当滚筒7的旋转从开始起经过规定时间时(在步骤S12为“是”)，控制部20通过使马达8停止来停止滚筒7的旋转。由此，准备过程结束。
接着，控制部20执行护理过程(步骤S4)。护理过程是指通过使用柔顺剂作为养护剂来护理滚筒7内的洗涤物L的纤维S(参照图1)的过程。如上所述，在护理过程之前的准备过程中从洗涤物L中去除了异物，因此在护理过程中，通过使涂剂遍及至去除了异物的洗涤物L的纤维S的细微部分，能充分地护理纤维S。护理过程包括供水处理、供水处理之后的预先处理、预浸泡处理之后的旋转处理以及旋转处理之后的摆动处理。
如图9所示，在供水处理(步骤S21)中，控制部20通过在关闭排水阀12的状态下打开供水阀11来向滚筒7内供水。此时，控制部20通过打开柔顺剂投入部6B的投入阀15来向水筒3内即滚筒7内自动投入所需量的柔顺剂。由此，溶解有柔顺剂的水即养护水自动生成并蓄于滚筒7内。当滚筒7内的水位上升至目标水位时，控制部20通过关闭供水阀11和投入阀15来结束供水处理。
此后，作为预浸泡处理(步骤S22)，控制部20在静止状态的滚筒7内将洗涤物L浸泡在养护水中。由此，能通过养护剂来将洗涤物L的纤维S(参照图1)仔细涂敷。当从预浸泡处理开始起经过例如几分钟的规定时间时(在步骤S23为“是”)，控制部20执行旋转处理(步骤S24)。
在旋转处理中，控制部20通过接着在滚筒7内蓄有养护水的状态下使马达8工作来使滚筒7例如以45rpm旋转。此时，既可以使滚筒7向同一方向连续旋转，也可以交替反复进行滚筒7的正转和反转。无论何种情况，滚筒7内的洗涤物L(参照图10中实线所示的洗涤物L)都在随着滚筒7的旋转上升至滚筒7内的最上部时(参照图10中双点划线所示的洗涤物L)因自重而往正下方向滚筒7内的水面W落下。
通过这样的旋转处理，可以改变洗涤物L中与养护水接触的区域，因此能 使养护水浸透至整个洗涤物L的深处，通过养护剂来有效地涂敷许多纤维S。然后，当从滚筒7开始旋转起经过例如几分钟的规定时间时(在步骤S25中为“是”)，控制部20通过使马达8停止来停止滚筒7的旋转。由此，旋转处理结束。
此后，控制部20执行摆动处理(步骤S26)。在摆动处理中，控制部20通过接着在滚筒7内蓄有养护水的状态下使马达8工作来使滚筒7像摇篮一样摆动。作为一个例子，如图11所示，在将水面W与从正面观察经过轴线J沿上下方向Z延伸的基准线P正交的状态下的滚筒7的旋转方向的位置设为0度的情况下，控制部20交替反复进行向逆时针+30度的滚筒7的摆动(参照图12)和向顺指针－30度的滚筒7的摆动(参照图13)。
通过这样的摆动处理，能使洗涤物L轻柔地摆动，此时，能通过养护剂来更有效地涂敷整个洗涤物L中的纤维S。然后，当从滚筒7摆动开始起经过例如几分钟的规定时间时(在步骤S27中为“是”)，控制部20通过使马达8停止来停止滚筒7的摆动。由此，摆动处理结束。
控制部30反复执行这些预浸泡处理、旋转处理以及摆动处理，直至这些处理的执行次数达到例如3次的规定次数。由此，能通过养护剂来将洗涤物L的所有纤维S无遗漏地涂敷。此后(在步骤S28中为“是”)，控制部30在打开排水阀12来排出养护水后结束护理过程。返回图6，控制部30在护理过程之后执行洗涤滚筒7内的洗涤物L的洗涤过程即清洗过程(步骤S5)和漂洗过程(步骤S6)。
在清洗过程(步骤S5)中，控制部30在关闭排水阀12的状态下打开供水阀11。由此，来自供水路4的水流入水筒3内而蓄留，因此水筒3内的水位上升。当水筒3内的水位上升至目标水位时，控制部20关闭供水阀11。此时，控制部20通过打开洗涤剂投入部6A的投入阀15来将所需量的洗涤剂自动投入到水筒3内。需要说明的是，洗涤剂也可以由使用者手动投入水筒3内。通过洗涤剂溶于自来水而生成的洗涤剂水蓄于水筒3内。
此后，控制部20通过马达8来使滚筒7旋转。由此，滚筒7内的洗涤物L被捶洗。在捶洗中，洗涤物L被反复进行提升一定程度之后向水面自然落下的翻滚。通过翻滚所产生的冲击、蓄于滚筒7的洗涤剂水中所含的洗涤剂成分， 从洗涤物L中去除污渍。在从翻滚开始起经过规定时间后，控制部20打开排水阀12进行排水。
在清洗过程的最后，控制部20执行脱水处理。在脱水处理中，控制部20在打开排水阀12的状态下使滚筒7脱水旋转。通过由滚筒7的脱水旋转产生的离心力，滚筒7内的洗涤物L被脱水。通过脱水而从洗涤物L渗出的水从排水路5排出至机外。
接着，控制部20执行漂洗过程(步骤S6)。在漂洗过程中，控制部20在关闭排水阀12的状态下将供水阀11打开规定时间来向水筒3中蓄留自来水至目标水位后，通过马达8来使滚筒7旋转。然后，反复进行上述的翻滚，因此洗涤物L被滚筒7内的自来水漂洗。需要说明的是，控制部20也可以通过在打开供水阀11时还打开柔顺剂投入部6B的投入阀15来将所需量的柔顺剂自动投入水筒3内。护理过程中投入的柔顺剂的所需量与漂洗过程中的柔顺剂的所需量不必相同。在从翻滚开始起经过规定时间后，当控制部20打开排水阀12进行排水来执行上述的脱水处理时，漂洗过程结束。
接着，作为脱水过程(步骤S7)，控制部20在打开排水阀12的状态下使滚筒7脱水旋转。也就是说，脱水过程的内容与清洗过程的最后阶段的脱水处理、漂洗过程的最后阶段的脱水处理的内容大致相同。也可以将脱水处理称为中间脱水过程并将脱水过程称为最终脱水过程。在最终脱水过程和中间脱水过程中，滚筒7的转速、旋转时间等也可以不同。随着脱水过程的结束，本次洗涤运转结束。
如上所述，滚筒7内的洗涤物L在护理过程中通过养护剂来对纤维S进行护理后在洗涤过程中被洗涤。由养护剂进行了护理的纤维S处于纤维S的表面被涂覆了养护剂的状态。
因此，在洗涤过程中，纤维S彼此不直接接触，因此能抑制由纤维S彼此的摩擦引起的洗涤物L的发硬。此外，由养护剂进行了护理的纤维S的表面维持角质层K整齐的平滑状态(参照图2)，因此在洗涤过程中纤维S彼此不易缠绕，因此能抑制洗涤物L的收缩。由此，能以不使洗涤物L劣化的方式进行洗涤。此外，对于已经处于损伤状态的纤维S，也能通过护理过程来进行补修和再生。
而且，在纤维S的表面被涂覆了养护剂的洗涤物L中，由于水难以渗入纤维S的内部，因此水分保有率低。因此，在上述的脱水处理、脱水过程中，能在短时间内将洗涤物L脱水。脱水是洗涤物L劣化的原因之一，因此通过在短时间内将洗涤物L脱水，能进一步抑制由洗涤运转引起的洗涤物L的劣化。
本发明不限定于以上所说明的实施方式，能在技术方案所记载的范围内进行各种变更。
例如，在护理过程中，也可以使用柔顺剂以外的养护剂，在该情况下，也可以在洗涤剂投入部6A和柔顺剂投入部6B之外设置养护剂专用的投入部6(未图示)。
此外，可以是，在洗涤运转中，除了如上所述执行准备过程和护理过程的护理专用程序之外，还存在省略了准备过程和护理过程的常用程序，使用者能通过操作显示操作部17来选择任一程序。
