Description

洗衣机 技术领域
本发明涉及一种洗衣机，其直到结束预定时刻为止，可执行使洗涤结束并且对衣物等被洗涤物的完好情况、清洗力有所重视的预约运转。
背景技术
以往，已知有一种洗衣机，具备：洗衣机主体；洗涤桶，配置在洗衣机主体的内部；以及电机，赋予用于使投入洗涤桶内的衣物等被洗涤物旋转的驱动力，直到使用者输入的结束预定时刻为止，能自动地结束对被洗涤物进行洗涤的多项过程(例如洗涤过程、漂洗过程以及脱水过程)的预约运转。在专利文献1中公开了这样的能进行预约运转的洗衣机。专利文献1中公开的洗衣机即使被操作了预约运转开始键，也不会立即开始洗涤动作，而是从预约运转开始键被操作之后经过了预约等待时间后，才真正开始洗涤运转。
现有技术文献
专利文献
专利文献1：日本特开2004-65408号公报
发明所要解决的问题
然而，一般的洗衣机在并非预约运转的普通洗涤运转中，倾向于注重运转时间的缩短，例如增大电机的转速，提高洗涤桶内的被洗涤物的转速，提高每单位时间的清洗力。然而，当像这样提高转速时被洗涤物容易发生损伤、褶皱，为了确保运转时间的缩短和清洗力，多少会牺牲被洗涤物的完好情况。
另一方面，具有如上所述的预约运转功能的洗衣机除了经过预约等待时间后开始洗涤运转外，通常会以大致相同的条件进行普通的洗涤运转和预约运转。因此，对于专利文献1中公开的洗衣机，从考虑在普通的洗涤运转和预约运转中使各过程的运转时间(执行时间)以及各过程中的所述电机的转速大致相同的方面、以及考虑在不需要考虑运转时间的缩短的预约运转的情况下也牺牲了被洗涤物的完好情况的方面来看，具有改善的余地。
发明内容
本发明的目的在于提供一种洗衣机，其直到结束预定时刻为止，可执行使洗涤结束并且对衣物等被洗涤物的完好情况、清洗力有所重视的预约运转。
用于解决问题的方案
本发明为了达成该目的采用如下方案。
即，本发明的洗衣机具备：洗衣机主体，具有可任意输入洗涤的结束预定时刻的输入部；洗涤桶，配置于该洗衣机主体的内部；以及电机，赋予用于使收容于该洗涤桶内的被洗涤物旋转的驱动力，并且直到所述结束预定时刻为止，可执行使洗涤被洗涤物的多项过程结束的预约运转，所述洗衣机的特征在于，具备：时间取得单元，在所述多项过程中的最初的过程开始前，取得直到基于所述结束预定时刻所设定的结束目标时刻为止的剩余时间；以及模式决定单元，基于所述时间取得单元所取得的剩余时间，决定是以普通预约模式来执行所述多项过程的每一项，还是以特殊预约模式来执行所述多项过程的每一项，其中，所述普通预约模式是将所述电机的平均转速设为规定值并以规定的执行时间来执行所述多项过程的每一项的模式，所述特殊预约模式是与该普通预约模式相比，将所述电机的平均转速设定得更小并且将执行时间设定得更长的模式。
具体而言，本发明优选采用如下方案：所述多项过程为洗涤过程、漂洗过程以及脱水过程，所述模式决定单元在判断出所述时间取得单元所取得的剩余时间为洗涤过程、漂洗过程以及脱水过程都以特殊预约模式来执行的情况下的所需时间以上时，决定以特殊预约模式来执行所有的过程；在判断出所述时间取得单元所取得的剩余时间不为洗涤过程、漂洗过程以及脱水过程都以特殊预约模式来执行的情况下的所需时间以上时，决定以普通预约模式来执行所有的过程。
或者，本发明优选采用如下方案：所述多项过程为洗涤过程、漂洗过程以及脱水过程，所述模式决定单元在判断出所述时间取得单元所取得的剩余时间为洗涤过程、漂洗过程以及脱水过程都以特殊预约模式来执行的情况下的所需时间以上时，决定以特殊预约模式来执行所有的过程；在判断出所述剩余时间不为以特殊预约模式来执行所有的过程的情况下的所需时间以上时，当判断出该剩余时间为所述多项过程中的一部分过程以特殊预约模式来执行、其他过程以普通预约模式来执行的情况下的所需时间以上时，决定仅对一部分过程以特 殊预约模式来执行。
或者，本发明优选采用如下方案：所述多项过程为洗涤过程、漂洗过程以及脱水过程，所述时间取得单元除了在最初的过程即洗涤过程开始前之外，在漂洗过程开始前以及脱水过程开始前，也分别取得直到所述结束目标时刻为止的剩余时间，所述模式决定单元每逢所述时间取得单元取得剩余时间时，都基于该剩余时间来决定下一项过程是以普通预约模式来执行还是以特殊预约模式来执行。
此外，本发明优选采用如下方案：将比由所述输入部输入的结束预定时刻提前规定时间的时刻设定为结束目标时刻。
发明效果
根据如上所述的本发明，在经由洗衣机主体的输入部输入结束预定时刻并进行预约运转时，时间取得单元取得在最初的过程开始前到结束目标时刻为止的剩余时间，模式决定单元能根据该剩余时间，决定是以普通预约模式来执行各过程，还是以特殊预约模式来执行各过程。特殊预约模式由于与普通预约模式相比电机的平均转速更小，因此洗涤桶内的被洗涤物的转速变小，能减少被洗涤物的损伤、褶皱，进而，由于与普通预约模式相比执行时间更长，因此洗涤桶内的被洗涤物的转速变小，因此能弥补降低了的每单位时间的清洗力、漂洗力以及脱水力。因此，本发明在直到基于结束预定时刻所设定的结束目标时刻为止的期间内时间上有富余的情况下，能执行特殊预约模式，直到结束预定时刻为止，可结束洗涤并且执行对衣物等被洗涤物的完好情况、清洗力有所重视的预约运转。
具体而言，本发明在判断剩余时间为以特殊预约模式执行所有过程的情况下的所需时间以上时，以特殊预约模式执行所有过程，否则，决定以普通预约模式执行所有过程，根据本发明，直到结束目标时刻为止，可结束洗涤，并且以简单的控制实现，减少被洗涤物的损伤、褶皱的预约运转。
或者，本发明在判断剩余时间为仅对一部分过程以特殊预约模式来执行的情况下的所需时间以上时，决定仅对一部分过程以特殊预约模式来执行，根据本发明，在时间没有充裕到能以特殊预约模式来执行所有的过程的程度的情况下，通过仅对一部分过程以特殊预约模式来执行，能增加执行可以减轻被洗涤物的损伤、褶皱的预约运转的机会。
或者，本发明每逢取得剩余时间时，都会决定是执行普通预约模式还是执行特殊预约模式，根据本发明，能在各过程开始前重新评估是执行普通预约模式还是执行特殊预约模式，即使在需要进行非常规动作等，产生了时间损耗的情况下，直到结束预定时刻为止，也能结束洗涤。
此外，根据比由所述输入部输入的结束预定时刻提早规定时间的时刻设定为结束目标时刻的本发明，即使在需要进行非常规动作等产生了时间损耗的情况下，也能以规定时间来弥补该损耗，能在截止到结束预定时刻为止的期间内结束洗涤。此外，通过将所述规定时间设定为例如15分左右，能弥补时间损耗，并防止由于洗涤后的被洗涤物放置在洗涤桶内而产生臭味。

具体实施方式
以下，参照附图对本发明的实施方式进行说明。
<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。此外，图2是表示第一实施方式的洗衣机1的大致结构的纵剖视图。
本实施方式的洗衣机1具备：洗衣机主体2、外桶3、洗涤桶4、波轮5、驱动单元6以及控制部7(参照图3)。像这样的洗衣机1直到由输入部23输入的结束预定时刻为止，可执行使洗涤衣物的多项过程即洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程结束的预约运转(预约洗涤)。
洗衣机主体2为大致长方形，上表面20具有：开口21，用于将作为被洗涤物的衣物投入取出洗涤桶4；开闭盖22，可开闭该开口21，可通过打开开闭盖22，经由开口21将衣物投入取出洗涤桶4。此外，在洗衣机主体2的上表面20具有预约运转进程按钮、时刻设定按钮，运转开始按钮等，具有可任意输入洗涤进程以及洗涤的结束预定时刻等的输入部23(参照图1)。
图2所示的外桶3配置在洗衣机主体2的内部，是可蓄水的有底筒状构件。
洗涤桶4是在外桶3的内部与外桶3同轴配置且通过外桶3旋转自如地被支承的有底筒状构件。洗涤桶4的直径比外桶3的直径小，在其壁面具有许多通水孔(不图示)，也作为脱水桶发挥功能。在洗涤过程以及漂洗过程中通过该通水孔(不图示)产生水流，在中间脱水过程以及最终脱水过程中通过通水孔从设置在外桶3的排水口(未图示)流出水。
波轮(搅拌翼)5旋转自如地配置在洗涤桶4的底部41中央，搅拌蓄在外桶3的水从而产生水流。波轮5的转速越快该水流值就越大。此外，相对于后述各过程的执行时间的波轮5的旋转时间的占比越大，则水流值就越大。
驱动单元6包括电机61和离合器62，电机61使洗涤桶4以及波轮5旋转， 赋予用于使收纳在洗涤桶4的衣物旋转的驱动力。
具体而言，电机61使朝向洗涤桶4的底部41伸出的驱动轴63旋转，由此洗涤桶4进行旋转。此外，电机61所产生的旋转力通过切换离合器62，也赋予波轮5驱动力，使波轮5旋转。因此，洗衣机1在洗涤衣物的多项过程中，在洗涤过程以及漂洗过程中主要是仅使波轮5旋转，在中间脱水过程以及最终脱水过程中能使洗涤桶4和波轮5一体地高速旋转。
图3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7来控制。控制部7具有ROM71以及RAM72，通过由微型计算机执行存储在该ROM71的程序，从执行预定的运转动作。执行上述程序时所使用的数据(例如经由输入部23输入的结束预定时刻)等临时存储在RAM72。
除了上述的电机61以及离合器62之外，控制部7连接有用于供水至外桶3的供水阀24以及用于将外桶3内的水排出的排水阀25等作为控制对象与。需要说明的是，在上述的图2中省略了供水阀24以及排水阀25的图示。
此外，控制部7除了被输入来自上述的输入部23的信号之外，还被输入来自负荷量传感器26、作为时间取得单元的时间取得部27以及计时器28、水位传感器29等的信号。
负荷量传感器26检测收纳在洗涤桶4的衣物的重量等，控制部7能基于负荷量传感器26的检测结果，判断(求出)与衣物的量对应的负荷量。控制部7使用该负荷量，对提取自OM71的后述的电机61的转速、执行时间等数据进行调整，或者，从预先存储在ROM71的表格与读出负荷量对应的值，在同一模式下，衣物的量越多、供给至外桶3的水量越多，则洗涤时间设定得越长。需要说明的是，有时候也会基于从输入部23输入的水量来判断负荷量。此外，负荷量可以考虑将提取自ROM71的数据乘以负荷系数来进行调整。
时间取得部27在选择了预约运转进程的情况下，根据由输入部23输入的结束预定时刻取得直到控制部7所设定的结束目标时刻为止的剩余时间。结束目标时刻被设定为比结束预定时刻提前规定时间的时刻。规定时间优选为30分钟，更优选为约15分钟。通过设定这样的结束目标时刻，即使在有必要进行非常规动作，例如进行用于松开在脱水过程中偏倚于洗涤桶4内的衣物的注水动作等并产生了时间损耗的情况下，也能弥补损耗，能在直到结束预定时刻为止 的期间内结束洗涤。此外，通过将规定时间设定为例如30分钟以下，能弥补时间损耗，并且能防止预约运转后的衣物由于被放置在洗涤桶4内产生臭味。在本实施方式中，时间取得部27在洗涤衣物的多项过程中，在最初的过程即洗涤过程开始前取得剩余时间。
计时器28在各过程中取得从开始时起算的经过时间。水位传感器29检测外桶3内的水量。
这样的本实施方式的洗衣机1在选择了预约运转进程时，能执行将电机61的平均转速设为规定值且在规定的执行时间内执行的普通预约模式、或与普通预约模式相比电机61的平均转速更小且执行时间设定得更长的特殊预约模式，控制部7根据时间取得部27所取得的剩余时间，决定是以普通预约模式还是以特殊预约模式来执行各过程。即，控制部7也作为模式决定单元发挥功能。
在此，电机61的平均转速是指执行各过程时的电机61的平均转速，按每项过程进行定义。在本实施方式中，电机61的平均转速通过例如变频控制方式，通过根据提取自ROM71的电机61的转速变更电机61的转速来进行调整。
在非预约运转进程的普通的洗涤进程中有重视运转时间缩短的清洗，但在预约运转进程中，即使运转时间变长，只要截止结束预定时刻为止结束洗涤即可。特殊预约模式由于与普通预约模式相比，电机61的平均转速较小，因此能降低洗涤桶4内的被洗涤物的转速，能减少衣物的损伤、褶皱，进而，由于与普通预约模式相比执行时间较长，因此能弥补由于洗涤桶4内的衣物的转速变小而降低了的每单位时间的清洗力、漂洗力以及脱水力。因此，本实施方式的洗衣机1在基于直到结束预定时刻所设定的结束目标时刻为止的期间内时间充裕的情况下，能执行特殊预约模式，直到结束预定时刻为止，可执行使洗涤结束并且对衣物的完好情况、清洗力有所重视的预约运转。
ROM71预先存储普通预约模式下的电机61的转速以及执行时间(洗涤时间、中间脱水时间、漂洗时间、最终脱水时间)、以及特殊预约模式下的电机61的转速以及执行时间(洗涤时间、中间脱水时间、漂洗时间、最终脱水时间)等。
具体而言，作为洗涤时间，ROM71分别存储普通预约模式时适用的普通洗涤时间以及特殊预约模式时适用的特殊预约洗涤时间。此外，作为水流值分别存储普通预约模式时适用的普通水流值以及特殊预约模式时适用的特殊预约模 式水流值。水流值通过调整电机转速来进行调整，特殊预约模式水流值设定为比比普通水流值小。此外，水流值也可以通过调整相对于各过程的执行时间的波轮5的旋转时间的占比来进行调整。
此外，作为中间脱水时间，ROM71分别存储普通预约模式时适用的普通中间脱水时间以及特殊预约模式时适用的特殊预约中间脱水时间。此外，作为电机转速分别存储普通预约模式时适用的普通转速以及特殊预约模式时适用的特殊预约模式转速。特殊预约模式转速设定为比普通转速小的值。
此外，作为漂洗时间，ROM71分别存储普通预约模式时适用的普通漂洗时间以及特殊预约模式时适用的特殊预约漂洗时间。此外，在同一模式的洗涤过程和漂洗过程中使水流值不同的情况下，进一步地，作为漂洗过程用的水流值，分别存储普通预约模式时适用的普通水流值以及特殊预约模式时适用的特殊预约模式水流值。
进而，作为最终脱水时间，ROM71分别存储普通预约模式时适用的普通最终脱水时间以及特殊预约模式时适用的特殊预约最终脱水时间。此外，在同一模式的中间脱水过程和最终脱水过程中使电机转速不同的情况下，进一步地，作为最终脱水过程用的电机转速，分别存储普通预约模式时适用的普通转速以及特殊预约模式时适用的特殊预约模式转速。

<步骤SP13>
在步骤SP13中，等到判断出被输入了结束预定时刻(步骤SP12：是)，控制部7判断具有输入部23的运转开始按钮是否被按下。
<步骤SP14>
在步骤SP14中，等到判断出运转开始按钮被按下(步骤SP13：是)，控制部7根据负荷量传感器26的检测值等判断负荷量，并且获得特殊预约模式所需时间。特殊预约模式所需时间是在洗涤过程SP2、中间脱水过程SP3、漂洗过程SP4以及最终脱水过程SP5都以特殊预约模式来执行的情况下所需要的时间，可从预先存储在ROM71的数据，根据所述负荷量得到。例如，特殊预约模式所需时间可通过以负荷量调整预先存储在ROM71的作为基准的时间(各过程的执行时间、这些执行时间的合计值等)、或通过从预先存储在ROM71的表格读出与负荷量对应的值来获得。后述的其它所需时间也与此相同。
<步骤SP15>
在步骤SP15中，控制部7判断直到时间取得部27所取得的结束目标时刻为止的剩余时间是否为特殊预约模式所需时间以上。当判断剩余时间为特殊预约模式所需时间以上时，进入步骤SP16(步骤SP15：是)，当判断剩余时间不 为特殊预约模式所需时间以上时，进入步骤SP17(步骤SP15：否)。

<步骤SP27>
在步骤SP27中，控制部7根据由计时器28取得的经过时间，判断是否达到步骤SP22或步骤SP24中设定的洗涤时间。
<步骤SP28>
在步骤SP28中，等到达到洗涤时间，控制部7结束洗涤运转。
接下来，根据图7，详细地说明图4所示的步骤SP3的中间脱水过程的流程。
<步骤SP31>
在步骤SP31中，控制部7判断在图5所示的步骤SP16中，是否决定了以特殊预约模式执行所有的过程。即，判断是否为特殊预约模式。当判断为特殊预约模式时，进入步骤SP32(步骤SP31：是)，当判断不是特殊预约模式时，进入步骤SP34(步骤SP31：否)。
<步骤SP32>

<步骤SP37>
在步骤SP37中，控制部7根据由计时器28取得的经过时间，判断是否达到了步骤SP32或步骤SP34中设定的中间脱水时间。
<步骤SP38>
在步骤SP38中，等到达到中间脱水时间，控制部7结束中间脱水运转。
接下来，根据图8，详细地说明图4所示的步骤SP4的漂洗过程的流程。
<步骤SP41>

<步骤SP46>
在步骤SP46中，控制部7向驱动单元6以及供水阀24等发送信号，使漂洗运转开始，并且在计时器28上使经过时间的计数开始。使漂洗运转时的水流值为步骤SP43或步骤SP45中设定的水流值，水流值通过调整电机61的转速来进行调整。因此，在设定了特殊预约模式的情况下，与设定了普通预约模式的情况相比电机61的平均转速更小。
<步骤SP47>
在步骤SP47中，控制部7根据由计时器28取得的经过时间，判断是否达到了步骤SP42或步骤SP44中设定的漂洗时间。
<步骤SP48>
在步骤SP48中，等到达到漂洗时间，控制部7结束漂洗运转。
接下来，根据图9，详细地说明图4所示的步骤SP5的最终脱水过程的流程。
<步骤SP51>
在步骤SP51中，控制部7判断在图5所示的步骤SP16中，是否决定了以特殊预约模式执行所有的过程。即，判断是否为特殊预约模式。当判断为特殊预约模式时，进入步骤SP52(步骤SP51：是)，当判断不为特殊预约模式时，进入步骤SP54(步骤SP51：否)。
<步骤SP52>
在步骤SP52中，控制部7从ROM71获得特殊预约最终脱水时间，根据特殊预约最终脱水时来设定最终脱水时间。
<步骤SP53>
在步骤SP53中，控制部7从ROM71获得特殊预约模式转速，根据特殊预约模式转速来设定电机转速。
<步骤SP54>

<步骤SP55>
在步骤SP55中，控制部7从ROM71获得普通转速，根据普通转速来设定电机转速。
<步骤SP56>
在步骤SP56中，控制部7向驱动单元6以及排水阀25等发送信号，使最终脱水运转开始，并且在计时器28上使经过时间的计数开始。最终脱水运转时的电机转速为步骤SP53或步骤SP55中设定的电机转速。因此，在设定了特殊预约模式的情况下，与设定了普通预约模式的情况相比电机61的平均转速更小。
<步骤SP57>
在步骤SP57中，控制部7根据由计时器28取得的经过时间，判断是否达 到了步骤SP52或步骤SP54中设定的最终脱水时间。
<步骤SP58>
在步骤SP58中，等到达到最终脱水时间，控制部7结束最终脱水运转。
像这样，在判断通过时间取得部27取得的剩余时间为特殊预约模式所需时间以上的情况下，以特殊预约模式执行所有的过程，否则以普通预约模式执行，由此，直到结束目标时刻为止，能结束洗涤并且能以简单的控制实现能减少衣物损伤、褶皱的预约运转。
<第二实施方式>
图10是表示本发明的第二实施方式的洗衣机的预约模式的判断流程的流程图。本实施方式的洗衣机1的预约模式的判断流程的一部分与第一实施方式不同。除以下记载的方案以外与第一实施方式相同，省略说明。
<步骤SP15>
步骤SP1A的预约模式的判断中，在步骤SP15中，控制部7判断时间取得部27所取得的直到结束目标时刻为止的剩余时间是否为特殊预约模式所需时间以上，当判断剩余时间为特殊预约模式所需时间以上时，进入步骤SP16(步骤SP15：是)，当判断剩余时间不为特殊预约模式所需时间以上时，进入步骤SP18(步骤SP15：否)。
<步骤SP18>
在步骤SP18中，控制部7判断是否能以特殊预约模式执行一部分过程。具体而言，判断由时间取得部27取得的剩余时间是否为以特殊预约模式执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程中的一部分过程(例如中间脱水过程以及最终脱水过程)，以普通预约模式执行其它的过程(例如洗涤过程以及漂洗过程)的情况下的所需时间以上。需要说明的是，该所需时间是从预先存储在ROM71的数据，根据负荷量而得到的时间。当判断剩余时间为以特殊预约模式执行一部分过程，以普通预约模式执行其它的过程的情况下的所需时间以上时，进入步骤SP19(步骤SP18：是)，当判断剩余时间不为以特殊预约模式执行一部分过程，以普通预约模式执行其它过程的情况下的所需时间以上时，进入步骤SP20(步骤SP18：否)。
<步骤SP19>
在步骤SP19中，控制部7决定以特殊预约模式执行一部分过程，以普通预 约模式执行其它过程。
<步骤SP20>
在步骤SP20中，控制部7决定以普通预约模式执行所有的过程。
在如上所述的预约模式的判断SP1A之后，控制部7根据决定的预约模式，遵照图6～图9所示的洗涤过程SP2、中间脱水过程SP3、漂洗过程SP4以及最终脱水过程SP5的顺序依次进行运转。
像这样，在时间并未充裕到足够以特殊预约模式执行所有的过程的情况下，通过以特殊预约模式仅执行一部分过程，从而能增加执行可减少衣物的损伤、褶皱的预约运转的机会。
<第三实施方式>
根据图11～15说明以本发明的第三实施方式的洗衣机执行预约运转的情况的流程。图11是表示以预约运转进程进行洗涤的情况的流程的流程图。图12是表示预约运转进程中的洗涤过程SP2a的流程的流程图。图13是表示预约运转进程中的中间脱水过程SP3a的流程的流程图。图14是表示预约运转进程中的漂洗过程SP4a的流程的流程图。图15是表示预约运转进程中的最终脱水过程SP5a的流程的流程图。
在本实施方式中，时间取得部27(参照图3)除了在洗涤过程SP2a开始前之外，还在中间脱水过程SP3a开始前、漂洗过程SP4a开始前以及最终脱水过程SP5a开始前分别取得直到结束目标时刻为止的剩余时间。
此外，控制部7每逢时间取得部27取得剩余时间时，都根据该剩余时间，决定是以普通预约模式还是以特殊预约模式来执行下一项过程。
具体而言，首先，在以图11所示的预约运转进程进行洗涤的情况的大致流程中，在步骤SP1a中进行运转进程的设定。步骤SP1a的运转进程的设定的流程与图5所示的步骤SP11～SP14相同。然后，按照顺序执行洗涤过程SP2a、中间脱水过程SP3a、漂洗过程SP4a以及最终脱水过程SP5a的。
图12所示的步骤SP2a的洗涤过程，除了用判断由时间取得部27取得的剩余时间是否为第一特殊预约模式所需时间以上的步骤SP21a，代替确认是否为特殊预约模式的图6所示的步骤21之外，与图6所示的洗涤过程SP2的流程相同。第一特殊预约模式所需时间是以特殊预约模式执行洗涤过程SP2a、中间脱水过程SP3a、漂洗过程SP4a以及最终脱水过程SP5a的所需时间。当判断剩余时间 为第一特殊预约模式所需时间以上时进入步骤SP22，当判断剩余时间不为第一特殊预约模式所需时间以上时进入步骤SP24。
图13所示的步骤SP3a的中间脱水过程，除了用判断由时间取得部27取得的剩余时间是否为第二特殊预约模式所需时间以上的步骤SP31a，代替确认是否为特殊预约模式的图7所示的步骤31之外，与图7所示的中间脱水过程SP3的流程相同。第二特殊预约模式所需时间是以特殊预约模式执行中间脱水过程SP3a、漂洗过程SP4a以及最终脱水过程SP5a所需的时间。当判断剩余时间为第二特殊预约模式所需时间以上时进入步骤SP32，当判断剩余时间不为第二特殊预约模式所需时间以上时进入步骤SP34。
图14所示的步骤SP4a的漂洗过程，除了用判断由时间取得部27取得的剩余时间是否为第三特殊预约模式所需时间以上的步骤SP41a，代替确认是否为特殊预约模式的图8所示的步骤41之外，与图8所示的漂洗过程SP4的流程相同。第三特殊预约模式所需时间是以特殊预约模式执行漂洗过程SP4a以及最终脱水过程SP5a所需的时间。当判断剩余时间为第三特殊预约模式所需时间以上时进行步骤SP42，当判断剩余时间不为第三特殊预约模式所需时间以上时进入步骤SP44。
图15所示的步骤SP5a的最终脱水过程，除了用判断由时间取得部27取得的剩余时间是否为第四特殊预约模式所需时间以上的步骤SP51a，代替确认是否为特殊预约模式的图9所示的步骤51之外，与图9所示的最终脱水过程SP5的流程相同。第四特殊预约模式所要时间是以特殊预约模式执行最终脱水过程SP5a所需的时间。当判断剩余时间为第四特殊预约模式所需时间以上时进入步骤SP52，当判断剩余时间不为第四特殊预约模式所需时间以上以上时步骤SP54。需要说明的是，控制部7进行步骤SP21a～SP51a中的判断。此外，上述第一～第四特殊预约模式所需时间是由预先存储在ROM71的数据，根据负荷量得到的时间。
像这样，能在各过程SP2a、SP3a、SP4a、SP5a开始前重新评估是执行普通预约模式还是执行特殊预约模式，即使在需要进行非常规动作等并产生了时间损耗的情况下，直到结束预定时刻为止，也能结束洗涤。
需要说明的是，各部分的具体结构不仅局限于上述的实施方式。
例如，在上述实施方式中，通过基于从ROM71取出的特殊预约模式转速或 普通转速等来变更电机61的转速，从而调整电机61的平均转速，但不局限于该方案，也可以通过电机61的运转/停止控制，变更各过程中的电机61的运转时间和停止时间的比例，从而将电机61的平均转速调整为规定值。需要说明的是，在这种情况下，洗涤过程以及漂洗过程中的水流值通过调整相对于各过程的执行时间的波轮5的旋转时间的占比来进行调整。
此外，在上述实施方式中，虽然结束目标时刻设定为比结束预定时刻早的时刻，但也可以将结束目标时刻设定为与结束预定时刻相同的时刻。
此外，虽然上述实施方式是立式的洗衣机1，但也可以在滚筒式的洗衣机中进行上述的预约运转。在这种情况下，电机61使洗涤筒旋转。
进而，作为洗涤衣物的多项过程，不局限于洗涤过程SP2(SP2a)、中间脱水过程SP3(SP3a)、漂洗过程SP4(SP4a)以及最终脱水过程SP5(SP5a)，也可以采用这些过程以外的过程，或不采用这些过程中的任一项过程。
其它的结构也可以在不脱离本发明的技术精神的范围进行各种变更。
