Description

洗衣机 技术领域
本发明涉及一种洗衣机。
背景技术
在洗衣机中，洗衣机的洗涤桶会随着使用而受污，因此需要定期地洗净洗涤桶。以往，当洗涤后的洗涤物附着有可目视的大小的霉菌或者产生霉臭时，对霉菌感到不舒服的用户判断为洗净洗涤桶的时刻到来，通过使洗衣机执行洗涤桶的洗净运转或者将清洁剂(cleaner)加入洗涤桶中等来洗净洗涤桶。此外，用户有时也与洗涤桶的受污状况无关地根据洗衣运转的次数来定期洗净洗涤桶。
以洗衣运转后残留的洗涤剂、污垢所产生的生物膜为营养而产生洗涤桶内的霉菌。生物膜根据各种原因而增加，霉菌也根据生物膜的增加而增殖。其原因根据用户每次洗衣运转对洗衣机的使用状况而不同，因此应该洗净洗涤桶的时刻也根据每位用户而不同。
发明内容
发明所要解决的问题
本发明是鉴于该背景而完成的，其目的在于提供一种能在最佳的时刻通知需要洗净洗涤桶的洗衣机。
用于解决问题的方案
本发明是一种洗衣机，包括：洗涤桶，容纳洗涤物，可蓄水；洗涤单元，执行对所述洗涤桶内的洗涤物进行洗涤的洗衣运转；计算单元，每当所述洗涤单元执行洗衣运转时，通过将每次洗衣运转的正或负的状况分数与规定的基准分数相加来计算每次洗衣运转的独立分数；累计单元，累计所述独立分数；以及通知单元，当所述累计单元所累计的所述独立分数的累计值达到规定的阈值 时，通知需要洗净所述洗涤桶。
此外，本发明的特征在于，所述状况分数中包括与所述洗涤桶内的水位相关的水位分数，所述洗涤桶内的水位固定的洗衣运转的水位分数比所述洗涤桶内的水位变动的洗衣运转的水位分数高。
此外，本发明的特征在于，所述状况分数中包括与供水时向所述洗涤桶内供给的水的种类相关的种类分数，供水时向所述洗涤桶内供给洗澡水的洗衣运转的种类分数比供水时向所述洗涤桶内供给自来水的洗衣运转的种类分数高。
此外，本发明的特征在于，所述状况分数中包括与用于洗衣运转的处理剂相关的处理剂分数，使用超过规定量的量的处理剂的洗衣运转的处理剂分数比使用所述规定量以下的量的处理剂的洗衣运转的处理剂分数高。
此外，本发明的特征在于，所述洗衣机包括：洗净单元，执行所述洗涤桶的洗净运转；以及复位单元，当所述通知单元进行通知之后所述洗净单元执行了洗净运转时，将所述累计值复位为零。
发明效果
根据本发明，在洗衣机中，每当洗衣运转时，通过将表示此时的洗衣机的使用状况的状况分数与基准分数相加来计算独立分数。这样的独立分数的累计值准确地表示根据用户的独立的使用状况而进一步受污的洗涤桶的受污状况。当累计值达到阈值时，成为对洗净洗涤桶而言最佳的时刻，因此洗衣机能在该时刻向用户通知需要洗净洗涤桶。
此外，根据本发明，作为状况分数的一个例子的水位分数在因洗涤桶内的水位固定而容易产生霉菌的洗衣运转中高，在因洗涤桶内的水位变动而不易产生霉菌的洗衣运转中低。通过加上这样的水位分数而计算出的独立分数准确地表示因每次洗衣运转的洗涤桶内的水位而导致的洗涤桶的受污状况。因此，当独立分数的累计值达到阈值时，洗衣机能在最佳的时刻向用户通知需要洗净因洗涤桶内的水位而受污的洗涤桶。
此外，根据本发明，作为状况分数的一个例子的种类分数在通过供水时向洗涤桶内供给洗澡水而容易产生霉菌的洗衣运转中高，在通过供水时向洗涤桶内供给自来水而不易产生霉菌的洗衣运转中低。通过加上这样的种类分数而计 算出的独立分数准确地表示因每次洗衣运转的供水时的水的种类而导致的洗涤桶的受污状况。因此，当独立分数的累计值达到阈值时，洗衣机能在最佳的时刻向用户通知需要洗净因供水时的水的种类而受污的洗涤桶。
此外，根据本发明，作为状况分数的一个例子的处理剂分数在通过大量使用洗涤剂、柔顺剂等处理剂而容易产生霉菌的洗衣运转中高，在通过使用少量的处理剂而不易产生霉菌的洗衣运转中低。通过加上这样的处理剂分数而计算出的独立分数准确地表示因每次洗衣运转的处理剂的量导致的洗涤桶的受污状况。因此，当独立分数的累计值达到阈值时，洗衣机能在最佳的时刻向用户通知需要洗净因使用的处理剂的量而受污的洗涤桶。
此外，根据本发明，在洗衣机中，当在通知需要洗净洗涤桶后执行了洗涤桶的洗净运转时，独立分数的累计值被复位为零。由此，洗衣机能重新累计独立分数，以便下次也在最佳的时刻通知需要洗净洗涤桶。

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说明。图1是本发明的一个实施方式的洗衣机1的示意性纵剖右视图。将图1中的上下方向称为洗衣机1的上下方向Z。上下方向Z当中，将上侧称为上侧Z1，将下侧称为下侧Z2。
洗衣机1中包括立式洗衣机、滚筒洗衣机、双桶式洗衣机，以下，以省略烘干功能而仅执行洗衣运转的立式洗衣机为例对洗衣机1进行说明。洗衣机1包括：箱体2，构成洗衣机1的外轮廓；洗涤桶5，由配置于箱体2内的外桶3和内桶4构成；旋转翼6，容纳于内桶4内；电动马达7，产生使内桶4、旋转翼6旋转的转矩；以及传递机构8，切换马达7所产生的转矩的传递目标。
箱体2例如为金属制，形成为箱状。在箱体2的上表面2A形成有使箱体2的内外连通的开口2B。在上表面2A设有对开口2B进行开闭的门9。在上表面2A中的例如比开口2B靠前侧Y1的区域设有由触摸面板等构成的显示操作部10。显示操作部也可以分为液晶面板等显示部和开关、按钮等操作部而构成。
外桶3形成为在上端形成有开口3A的有底圆筒状。开口3A配置于箱体2 的开口2B的正下方。外桶3内可蓄水。排水路11从下侧Z2连接于外桶3，外桶3内的水从排水路11向机外排出。在排水路11的中途设有为了开始或停止排水而被开闭的排水阀12。
内桶4具有沿上下方向Z延伸的中心轴J，形成为比外桶3小一圈的有底圆筒状，能在内部容纳洗涤物Q。在内桶4的上端形成有出入口4A。出入口4A处于从下侧Z2与外桶3的开口3A及箱体2的开口2B连通的状态。洗衣机1的用户打开门9使开口2B、开口3A以及出入口4A敞开，使洗涤物Q出入于内桶4。
内桶4同轴地容纳于外桶3内，沿上下方向Z即纵向配置。容纳于外桶3内的状态的内桶4能绕中心轴J旋转。在内桶4形成有多个未图示的贯通孔，外桶3内的水能经由该贯通孔在外桶3与内桶4之间往来。在内桶4的底壁设有沿中心轴J向下侧Z2延伸出并贯通外桶3的底壁的管状的支承轴13。
旋转翼6是所谓的波轮，形成为以中心轴J为圆心的圆盘状，配置于内桶4的底壁上。在旋转翼6设有从其圆心沿中心轴J向下侧Z2延伸的旋转轴14。旋转轴14插通支承轴13的中空部分，旋转轴14的下端部位于比外桶3的底壁靠下侧Z2处。
马达7具有向上侧Z1突出并以中心轴J为中心进行旋转的输出轴15，配置于内桶4的下侧Z2。传递机构8是介于支承轴13和旋转轴14各自的下端部与输出轴15的上端部之间的电动离合器。传递机构8将马达7从输出轴15输出的转矩选择性地传递给支承轴13和旋转轴14中的一方或双方。当转矩被传递给支承轴13时内桶4旋转，当转矩被传递给旋转轴14时旋转翼6旋转。
与向外桶3和内桶4的供水相关联地，洗衣机1还包括：供水路16，用于将来自水龙头(未图示)的自来水供给至内桶4内；以及洗澡水供给路17，在箱体2内与供水路16汇合。供水路16的一端(未图示)被拉出至箱体2之外，连接于水龙头。供水路16的另一端作为配置于箱体2内的供水口16A，从上侧Z1面向内桶4的出入口4A。在供水路16中的配置于箱体2内的部分设有可开闭的供水阀18。
洗澡水供给路17的一端被拉出至箱体2之外并浸于浴缸内的洗澡水中。洗 澡水供给路17的另一端配置于箱体2内，连接于供水路16中的比供水阀18靠近供水口16A的下游部分。可以是，洗澡水供给路17中的被拉出至箱体2之外的部分可拆装于箱体2。在洗澡水供给路17设有将浴缸内的洗澡水吸入至洗澡水供给路17内并向供水路16送入的洗澡水泵19。
洗衣机1包括：控制部20，由微机等构成；门传感器21，检测门9的开闭；水位传感器22，检测洗涤桶5内的水位；以及存储部23，存储各种信息(参照图2)。马达7、传递机构8、显示操作部10、排水阀12、供水阀18、洗澡水泵19、门传感器21、水位传感器22以及存储部23分别与控制部20电连接。用户对显示操作部10的操作内容被输入至控制部20，控制部20控制显示操作部10的显示内容。门传感器21和水位传感器22各自的检测结果被输入至控制部20。控制部20参照存储于存储部23的信息、或者将新的信息存储于存储部23、或者更新存储部23内的信息。
控制部20通过控制马达7、传递机构8、排水阀12、供水阀18以及洗澡水泵19的动作来执行对洗涤桶5内的洗涤物Q进行洗涤的洗衣运转。该情况的控制部20作为洗涤单元的一个例子发挥功能。洗衣运转包括：清洗过程，对洗涤桶5的内桶4内的洗涤物Q进行清洗；漂洗过程，在清洗过程后对洗涤物Q进行漂洗；以及脱水过程，在漂洗过程后将洗涤物Q脱水。
在清洗过程中，控制部20首先通过在关闭了排水阀12的状态下将供水阀18打开规定时间来向洗涤桶5内供水(参照图1的虚线箭头)。需要说明的是，控制部20在供水时也可以不打开供水阀18而通过使洗澡水泵19工作来向洗涤桶5内供给洗澡水。在供水前或供水后的时刻，用户可以打开门9来从出入口4A向内桶4内投入洗涤剂。
当洗涤桶5内的水位上升至规定水位时，控制部20在停止供水后通过控制马达7和传递机构8来使旋转翼6旋转。由此，内桶4内的洗涤物Q通过被搅拌或由洗涤剂分解污垢而被清洗。最后，控制部20通过打开排水阀12来将洗涤桶5排水。
在漂洗过程中，控制部20首先通过在关闭了排水阀12的状态下将供水阀18打开规定时间来向洗涤桶5内蓄留自来水。完成了供水的控制部20通过控制马达7和传递机构8来使旋转翼6旋转。由此，内桶4内的洗涤物Q被漂洗。 在漂洗过程中，在供水前或供水后的时刻，用户可以打开门9来从出入口4A向内桶4内投入柔顺剂。柔顺剂渗透洗涤物Q。最后，控制部20将洗涤桶5排水。
在脱水过程中，控制部20在打开了排水阀12的状态下通过控制马达7和传递机构8来使内桶4以规定的脱水转速旋转。由此，内桶4内的洗涤物Q通过离心力作用而被脱水。
当通过反复进行洗衣运转而洗衣运转的运转次数增加时，在洗涤桶5内产生并增加生物膜。与此相应地，以生物膜为营养而生长的霉菌也增殖。生物膜在刚产生时为透明的膜，但当增加至肉眼可见的状态时，黑霉以覆盖生物膜的表面的整个区域的方式增殖。
图3～图9的各曲线图表示洗衣运转的运转次数与作为关于霉菌的产生情况的指标的霉菌水平的关系。在各曲线图中，横轴表示洗衣运转的运转次数，纵轴表示霉菌水平。需要说明的是，作为代替运转次数的指标，也可以使用洗衣运转的运转时间。当霉菌水平为0时，洗涤桶5内几乎不存在生物膜和霉菌。当洗涤桶5内的生物膜和霉菌增殖时，霉菌水平向100增加。当霉菌水平为100时，洗涤桶5内存在用户识别为需要洗净洗涤桶5的程度的霉菌。不过，在该状态下，通过洗净洗涤桶5，能去除霉菌和生物膜。
控制部20每当执行一次即一个循环的洗衣运转时，基于以下的式(1)计算每次洗衣运转的独立分数(point)T。式(1)被存储于存储部23。
独立分数T＝基准分数N+状况分数K…式(1)
式(1)中，基准分数N是在任何洗衣运转中都通用的规定的数值。状况分数K是表示每次洗衣运转的洗衣机1的使用状况的正或负的数值，通过实验等确定并存储于存储部23。在式(1)中，作为计算单元的一个例子，控制部20通过将每次洗衣运转的状况分数K与基准分数N相加来计算独立分数T。即，控制部30通过根据每次洗衣运转的状况进行加权来计算独立分数T。此外，每当计算独立分数T时，控制部20通过将本次的独立分数T与上次计算出的独立分数T相加来累计独立分数T。将控制部20累计出的独立分数T的累计值称为累计值X。该情况的控制部20为累计单元的一个例子。
状况分数K是基于实验结果等将洗涤桶5的易污性数值化的分数，有各个 种类。例如，清洗过程中包括供水后的洗涤桶5内的水位固定的模式和供水后的洗涤桶5内的水位变动的模式，用户能通过在洗衣运转开始前操作显示操作部10来选择任意的模式。控制部30通过在供水后也分别对排水阀12和供水阀18进行开闭或使洗澡水泵19工作来使洗涤桶5内的水位变动。
如图3所示，在洗涤桶5内的水位固定的模式(参照实线的线)下，霉菌水平比洗涤桶5内的水位变动的模式(参照虚线的线)增加得快。在洗涤桶5内的水位变动的模式下，通过使生物膜的产生变慢，也能使霉菌水平的增殖变慢。基于这样的倾向，状况分数K中包括与洗涤桶5内的水位相关的水位分数K1。清洗过程中的洗涤桶5内的水位固定的洗衣运转的水位分数K1A比清洗过程中的洗涤桶5内的水位变动的洗衣运转的水位分数K1B高。“分数高”是指生物膜容易增加，即容易产生霉菌。
在用户操作显示操作部10而选择了洗涤桶5内的水位固定的洗衣运转的情况下，控制部30将水位分数K1A与基准分数N相加，计算该洗衣运转的独立分数T。在用户操作显示操作部10而选择了洗涤桶5内的水位变动的洗衣运转的情况下，控制部30将水位分数K1B与基准分数N相加，计算该洗衣运转的独立分数T。
用户能通过在洗衣运转开始前操作显示操作部10来设定清洗过程中的供水是否使用洗澡水，即有无洗澡水。在无洗澡水的情况的供水时，控制部30通过打开供水阀18来执行自来水的供水。在有洗澡水的情况的供水时，控制部30通过使洗澡水泵19工作来执行洗澡水的供水。
如图4所示，在有洗澡水的设定(参照实线的线)下，比无洗澡水的设定(参照虚线的线)容易产生生物膜，因此霉菌水平增加得快。基于这样的倾向，状况分数K中包括与供水时向洗涤桶5内供给的水的种类相关的种类分数K2。供水时向洗涤桶5内供给洗澡水的洗衣运转的种类分数K2A比供水时向洗涤桶5内供给自来水的洗衣运转的种类分数K2B高。在用户操作显示操作部10而选择了有洗澡水的洗衣运转的情况下，控制部30将种类分数K2A与基准分数N相加，计算该洗衣运转的独立分数T。在用户操作显示操作部10而选择了无洗澡水的洗衣运转的情况下，控制部30将种类分数K2B与基准分数N相加，计算该洗衣运转的独立分数T。
霉菌水平的增加状况会根据洗涤剂、柔顺剂之类的处理剂的使用量而发生变化。例如，如图5所示，以投入与洗涤物Q的量对应的规定量的洗涤剂的洗衣运转(参照实线的线)为基准，在投入比规定量少的洗涤剂的洗衣运转(参照虚线的线)中，霉菌水平的增加慢，在投入比规定量多的洗涤剂的洗衣运转(参照单点划线的线)中，霉菌水平的增加快。此外，如图6所示，在漂洗过程中不使用柔顺剂的无柔顺剂的洗衣运转(参照实线的线)中，霉菌水平的增加慢。另一方面，漂洗过程中使用柔顺剂的有柔顺剂的洗衣运转(参照虚线的线)中的霉菌水平的增加比无柔顺剂的洗衣运转的情况快两倍左右。
基于这样的倾向，状况分数K中包括与用于洗衣运转的处理剂相关的处理剂分数K3。使用超过规定量的量的处理剂的洗衣运转的处理剂分数K3A比使用所述规定量以下的量的处理剂的洗衣运转的处理剂分数K3B高。当着眼于柔顺剂时，所述规定量为零。在用户操作显示操作部10而选择了有柔顺剂的洗衣运转的情况下，控制部30将处理剂分数K3A与基准分数N相加，计算该洗衣运转的独立分数T。在用户操作显示操作部10而选择了无柔顺剂的洗衣运转的情况下，控制部30将处理剂分数K3B与基准分数N相加，计算该洗衣运转的独立分数T。
当着眼于洗涤剂时，所述规定量为上述的规定量，洗衣机1中设有检测洗涤剂的投入量的洗涤剂传感器。在洗涤剂的投入量比规定量少的情况、洗涤剂的投入量为规定量的情况以及洗涤剂的投入量比规定量多的情况的各个洗衣运转中，设定有按照上述顺序变高的处理剂分数K3，控制部30将与洗涤剂的投入量对应的处理剂分数K3与基准分数N相加来计算独立分数T。
漂洗过程中包括洗涤桶5内蓄水至规定水位的蓄水漂洗和一边排水一边供水的注水漂洗，用户能通过在洗衣运转开始前操作显示操作部10来选择蓄水漂洗和注水漂洗中的哪种漂洗。控制部30在蓄水漂洗中在供水后使排水阀12和供水阀18双方成为关闭的状态，而在注水漂洗中在供水后使排水阀12和供水阀18双方成为打开的状态。
如图7所示，在蓄水漂洗(参照实线的线)中，霉菌水平比注水漂洗(参照虚线的线)增加得快。反过来说，只要采用注水漂洗，就能使霉菌水平的增加变慢。基于这样的倾向，状况分数K中包括与漂洗方式相关的漂洗分数K4。 进行蓄水漂洗的洗衣运转的漂洗分数K4A比进行注水漂洗的洗衣运转的漂洗分数K4B高。在用户操作显示操作部10选择了蓄水漂洗的洗衣运转中，控制部30将漂洗分数K4A与基准分数N相加来计算独立分数T。在用户操作显示操作部10选择了注水漂洗的洗衣运转中，控制部30将漂洗分数K4B与基准分数N相加来计算独立分数T。
例如，霉菌水平的增加状况会根据洗衣运转后的停止期间的门9的开闭状态而发生变化。如图8所示，在门9打开的状态下置之不顾后进行的洗衣运转(参照实线的线)中，霉菌水平的增加慢，在门9关闭的状态下置之不顾后进行的洗衣运转(参照虚线的线)中，霉菌水平的增加快1.5倍左右。基于这样的倾向，状况分数K中包括门9的开闭状态的开闭分数K5。门9关闭的状态下置之不顾后进行的洗衣运转的开闭分数K5A比门9打开的状态下置之不顾后进行的洗衣运转的开闭分数K5B高。在洗衣运转开始前的状态下门传感器21检测到门9的关闭状态的情况下，控制部30将开闭分数K5A与基准分数N相加，计算该洗衣运转的独立分数T。在洗衣运转开始前的状态下门传感器21检测到门9的打开状态的情况下，控制部30将开闭分数K5B与基准分数N相加，计算该洗衣运转的独立分数T。
顺便一提，如图9所示，无论洗涤剂是液体洗涤剂和粉末洗涤剂中的哪一种，霉菌水平的增加情况都相同。图10是表示洗净洗涤桶5后的经过时间与霉菌水平的关系的曲线图。在该曲线图中，横轴表示经过时间，其单位为“时间”，纵轴表示霉菌水平。用于洗净洗涤桶5的桶清洁剂有氯系的桶清洁剂和氧系的桶清洁剂。在使用氯系的桶清洁剂对洗涤桶5进行洗净的情况下(参照虚线的线)，桶清洁剂的洗净效果发挥得快，由此当从洗净洗涤桶5后经过24小时左右时，洗涤桶5内的霉菌水平降低至几乎为零的状态。另一方面，在使用氧系的桶清洁剂对洗涤桶5进行洗净的情况(参照实线的线)下，即使经过72小时后，洗涤桶5内的霉菌水平也不会降低至零，会残留黑霉。
图11是表示温度、湿度以及洗涤桶5内的霉菌水平的关系的图。洗衣机1也可以包括：温度传感器24，检测周围的温度即环境温度；以及湿度传感器25，检测周围的湿度即环境湿度(参照图2)。温度传感器24和湿度传感器25各自的检测结果被实时地输入至控制部20。在周围的温度为25度以上且38度以下 的情况下，霉菌水平为中等程度。在周围的湿度为80％以上的情况下，霉菌水平也为中等程度。而且，在周围的温度为25度以上且38度以下并且周围的湿度为80％以上的情况下，霉菌水平高，接近于100。另一方面，在周围的温度低于25度并且周围的湿度低于80％的情况下，霉菌水平低，接近于零。
基于这样的倾向，状况分数K中包括与温度、湿度相关的环境分数K6。周围的温度为25度以上且38度以下并且周围的湿度为80％以上的情况的环境分数K6A比周围的温度为25度以上且38度以下或周围的湿度为80％以上的情况的环境分数K6B高。此外，环境分数K6B比周围的温度低于25度并且周围的湿度低于80％的情况的环境分数K6C高。控制部30基于洗衣运转中的规定时刻的温度传感器24和湿度传感器25各自的检测结果来确定环境分数K6，将该环境分数K6与基准分数N相加，计算该洗衣运转的独立分数T。
如上所述，控制部20按每次洗衣运转来确定本次洗衣运转中的各种状况分数K，将确定后的状况分数K与基准分数N相加来计算独立分数T，将计算后的独立分数T存储于存储部23。该独立分数T是有可能因每次洗衣运转而异的独立的值。需要说明的是，状况分数K不限于正值，也可能是负值，因此独立分数T也可能比基准分数N小。需要说明的是，也可以有状况分数K为零的情况。而且，每当计算独立分数T时，控制部20通过将本次计算出的独立分数T与存储于存储部23的上次的独立分数T相加，来累计独立分数T，将独立分数T的累计值X存储于存储部23。累计值X随着反复进行洗衣运转而增加。
图12是表示洗衣运转的次数与累计值X的关系的曲线图。在该曲线图中，横轴表示运转次数，纵轴表示独立分数T的累计值X。与累计值X有关的规定的阈值Y通过实验等预先确定并存储于存储部23。阈值是表示处于正要产生霉菌的状态或虽然产生了霉菌但能充分去除的状态时的洗涤桶5的值。本实施方式中的阈值的一个例子为1600分。
在用户按照设想到的普通的使用方法来使用洗衣机1的情况(参照图12的实线的线)下，当洗衣运转的运转次数达到40次左右时，独立分数T的累计值X达到阈值Y。另一方面，在用户按照霉菌水平会变低的最佳使用方法来使用洗衣机1的情况(参照图12的虚线的线)下，累计值X的增加缓慢，因此直至洗衣运转的运转次数达到54次左右，累计值X都不会达到阈值Y。但是，在用 户按照霉菌水平会变高的最差的使用方法来使用洗衣机1的情况(参照图12的单点划线的线)下，累计值X的增加快，因此当洗衣运转的运转次数达到30次左右时，累计值X就会达到阈值Y。
当控制部20所累计的独立分数T的累计值X达到阈值Y时，控制部20通过在显示操作部10闪烁显示“桶洗净标记(sign)”等，在从洗衣运转结束后经过例如2小时的规定期间内，向用户通知需要洗净洗涤桶5即洗涤桶5的洗净时刻到来。该情况下的控制部20和显示操作部10作为通知单元的一个例子发挥功能。需要说明的是，也可以是，控制部20除了显示操作部10中的显示以外，或者代替该显示，通过用蜂鸣器等发出的声音来向用户通知需要洗净洗涤桶5。需要说明的是，可以是，这样的通知功能在洗衣机1的初始设定中被设为有效，并能通过用户对显示操作部10的操作来设定是否启用通知功能。
控制部20作为洗净单元的一个例子，能执行洗涤桶5的洗净运转。当被通知需要洗净洗涤桶5的用户通过操作显示操作部10来命令执行洗净运转时，控制部20执行洗净运转。具体而言，控制部20通过在关闭了排水阀12的状态下将供水阀18打开规定时间来向洗涤桶5内蓄留自来水。之后，当用户将上述的桶清洁剂投入洗涤桶5内时，控制部20维持洗涤桶5内蓄有溶解有桶清洁剂的水的状态一定时间。由此，洗涤桶5内的霉菌、生物膜被桶清洁剂分解而被去除。需要说明的是，控制部20也可以通过中途使内桶4、旋转翼6旋转来搅拌洗涤桶5内的水，由此促进洗涤桶5内的霉菌、生物膜的去除。当持续规定时间时，控制部20通过打开排水阀12来执行洗涤桶5的排水从而结束洗净运转。
此外，控制部20例如在结束洗净运转的时刻更新存储部23，将存储部23中的独立分数T的累计值复位为零。该情况的控制部20作为复位单元的一个例子发挥功能。
如上所述，在洗衣机1中，每当洗衣运转时，通过将表示此时的洗衣机1的使用状况的状况分数K与基准分数N相加来计算独立分数T。这样的独立分数T的累计值X准确地表示根据用户的独立的使用状况而进一步受污的洗涤桶5的受污状况。例如，通过加上作为状况分数K的一个例子的水位分数K1而计算出的独立分数T准确地表示因每次洗衣运转的洗涤桶5内的水位而导致的洗涤桶5的受污状况。此外，通过加上作为状况分数K的一个例子的种类分数K2 而计算出的独立分数T准确地表示因每次洗衣运转的供水时的水的种类而导致的洗涤桶5的受污状况。通过加上作为状况分数K的一个例子的处理剂分数K3而计算出的独立分数T准确地表示因每次洗衣运转的处理剂的量而导致的洗涤桶5的受污状况。
并且，当累计值X达到阈值Y时，对因洗涤桶5内的水位、供水时的水的种类、处理剂的量等而受污的洗涤桶5进行洗净的最佳时刻到来，因此洗衣机1能在该时刻向用户通知需要洗净洗涤桶5。因此，虽然产生了生物膜，但能在大量产生霉菌前于早期阶段促使用户洗净洗涤桶5。而且，在洗衣机1中，当在通知需要洗净洗涤桶5后执行了洗涤桶5的洗净运转时，独立分数T的累计值X被复位为零。由此，洗衣机1能重新累计独立分数T，以便下次也在最佳的时刻通知需要洗净洗涤桶5。
本发明不限定于以上说明的实施方式，能在技术方案所记载的范围内进行各种变更。
例如，在上述的实施方式中，设为在通过加分方式增加的累计值X增加至阈值Y的情况下通知需要洗净洗涤桶5，但也可以设为在通过减分方式减少的累计值X减少至阈值Y的情况下通知需要洗净洗涤桶5。
