Description

洗衣机 技术领域
本发明涉及一种洗衣机。
背景技术
一直以来，洗衣机进行以驱动马达为驱动源对收容在洗涤脱水桶、滚筒等洗涤桶的洗涤物进行洗涤的洗涤运转。例如，在全自动洗衣机中，在洗涤脱水桶内的底部具备波轮，驱动马达在洗涤脱水桶内蓄有水的状态下工作，波轮进行旋转。由此，对洗涤物施加机械力，洗涤物被清洗或漂洗。
在洗衣机中，例如，通过增大驱动马达的转矩或延长接通时间，能增大施加于洗涤物的机械力，能提高洗涤物的洗净力。另一方面，由于需要为驱动马达提供较多的电力，因此驱动马达的线圈的温度容易上升。
在洗衣机未被使用的期间，线圈的温度低，不久就变成与驱动马达周围的温度大致相同的温度。但是，在洗涤物多，用户连续进行洗涤运转这样的情况下，在上一次洗涤运转之后，在驱动马达的线圈的温度不够低的情况下就开始本次的洗涤运转。因此，如上所述，在增大施加给洗涤物的机械力而使洗涤物的洗净力提高的情况下，当连续进行洗涤运转时，驱动马达的线圈的温度过高，可能会超过法律等规定的上限温度。
以下的专利文献1中记载了一种洗衣机，其具备由转子和具有线圈的定子构成的马达以及检测定子的温度的热敏电阻，通过连续进行洗涤运转等，在热敏电阻于洗涤运转中检测到规定值以上的温度的情况下，马达停止。
上述洗衣机中，当定子的温度为规定值以上时马达会停止，即，洗涤运转会中断，因此虽然能避免马达温度异常，但是该次洗涤运转中的洗净力可能会大幅度下降。

发明内容
发明所要解决的问题
因此，本发明的目的在于提供一种洗衣机，其能良好地避免驱动马达的线圈超过上限温度。
用于解决问题的方案
本发明的主要方案涉及一种洗衣机，其进行通过驱动马达的工作来施加机械力从而对收容在洗涤桶内的洗涤物进行洗涤的洗涤运转。本方案的洗衣机具备：线圈温度传感器，检测所述驱动马达的线圈的温度或与该线圈的温度相关的温度来作为线圈温度；以及控制部。其中，所述控制部根据在所述洗涤桶内蓄有水的状态下在所述驱动马达进行工作之前检测出的所述线圈温度，设定该次所述洗涤运转中的运转条件。
根据上述结构，当线圈的温度低且与上限温度差距大时，线圈的温度可以容易上升，因此，能设定通过驱动马达的工作来对洗涤物施加大的机械力或长时间地施加机械力这样的运转条件，能确保高洗净力。另一方面，当线圈的温度高且与上限温度差距小时，可以设定通过驱动马达的工作来对洗涤物施加小的机械力或较短时间地施加机械力这样的运转条件，以使线圈的温度不容易上升，能防止线圈的温度超过上限温度。
而且，由于该结构中，即使在线圈的温度高的情况下，洗涤运转也会在设定的运转条件下进行到最后，因此，与在线圈的温度可能超过上限温度时中断洗涤运转的结构不同，不容易发生洗净力大幅度下降的情况，能进行洗净力稳定的洗涤运转。
本方案的洗衣机中，可以采用如下结构：还具备周围温度传感器，其检测所述驱动马达的周围的温度或与该周围的温度相关的温度来作为周围温度。这种情况下，所述控制部根据在所述洗涤桶内蓄有水的状态下在所述驱动马达进行工作之前检测出的所述线圈温度与所述周围温度的温度差来设定所述运转条件。
根据上述结构，能根据由线圈温度传感器检测出的线圈温度与由周围温度传感器检测出的周围温度的温度差来判定驱动马达的线圈的温度，设定运转条件。
本方案的洗衣机中，可以采用如下结构：还具备波轮，其配置于所述洗涤桶的底部，通过所述驱动马达的转矩来进行旋转。这种情况下，所述运转条件可以包括根据洗涤物的负荷量来向所述洗涤桶内蓄水时的水位。对于相同的负荷量，所述控制部在所述线圈温度相对较低时使所述水位相对变低，在所述线圈温度相对较高时使所述水位相对变高。
对于相同的负荷量，洗涤桶的水位越低，洗涤物越靠近波轮，因此，容易对洗涤物作用强水流或洗涤物容易被波轮摩擦，施加给洗涤物的机械力变大。另一方面，波轮受到的来自洗涤物的负荷变大，对驱动马达的负荷也变大，因此，线圈的温度容易上升。
根据上述结构，当线圈的温度低时，对于相同的负荷量，洗涤桶的水位变低，因此，通过驱动马达的工作而施加给洗涤物的机械力变大。由此，能确保高洗净力。另一方面，当线圈的温度高时，对于相同的负荷量，洗涤桶的水位变高，因此，波轮受到的来自洗涤物的负荷变小，对驱动马达的负荷也变小。由此，线圈的温度不容易上升，因此，能防止线圈的温度超过上限温度。
本方案的洗衣机中，所述运转条件可以包括所述驱动马达不工作而洗涤物浸泡放置在水中的浸泡放置时间。这种情况下，所述控制部设为：在所述线圈温度相对较低时不存在所述浸泡放置时间或使所述浸泡放置时间相对变短，在所述线圈温度相对较高时存在所述浸泡放置时间或使所述浸泡放置时间相对变长。
根据上述结构，当线圈的温度低时，不存在浸泡放置时间或使浸泡放置时间变短，因此，运转时间不容易延长。另一方面，当线圈的温度高时，存在浸泡放置时间或使浸泡放置时间变长，因此，线圈容易在洗涤物浸泡放置在水中的期间冷却。由此，线圈的温度不容易上升，因此，能防止线圈的温度超过上限温度。
本方案的洗衣机中，所述运转条件可以包括在使所述驱动马达工作时提供 的电力的大小。这种情况下，所述控制部在所述线圈温度相对较低时使所述电力相对变大，在所述线圈温度相对较高时使所述电力相对变小。
提供给驱动马达的电力越大，驱动马达的转矩越大，因此，通过驱动马达的工作而施加给洗涤物的机械力变大。另一方面，由于线圈中容易流过大电流，因此线圈的温度容易上升。
根据上述结构，当线圈的温度低时，提供给驱动马达的电力变大，因此，通过驱动马达的工作而施加给洗涤物的机械力变大。由此，能确保高洗净力。另一方面，当线圈的温度高时，提供给驱动马达的电力变小，因此，线圈的温度不容易上升。由此，能防止线圈的温度超过上限温度。
本方案的洗衣机中，所述运转条件可以包括使所述驱动马达间歇工作时的断开时间的比例。这种情况下，所述控制部在所述线圈温度相对较低时使所述断开时间的比例相对变小，在所述线圈温度相对较高时使所述断开时间的比例相对变大。
根据上述结构，当线圈的温度低时，断开时间的比例变小，相应地，接通时间的比例变大，因此，通过驱动马达的工作而对洗涤物施加机械力的时间变长。由此，能确保高洗净力。另一方面，当线圈的温度高时，断开时间的比例变大，因此，线圈的温度不容易上升。由此，能防止线圈的温度超过上限温度。
本方案的洗衣机中，可以采用如下结构：还具备周围温度传感器，其检测所述驱动马达的周围的温度或与该周围的温度相关的温度来作为周围温度。这种情况下，所述控制部根据所述周围温度来设定所述运转条件。
根据上述结构，能设定在驱动马达周围的温度高且线圈的温度容易上升时通过驱动马达的工作来对洗涤物施加小的机械力或较短时间地施加机械力这样的运转条件，能进一步防止线圈的温度超过上限温度。

马达驱动部103例如是驱动器IC，包括驱动电路103a和温度传感器103b。驱动电路103a根据来自控制部101的控制信号，对驱动马达31进行驱动。驱动电路103a将与转速传感器(未图示)检测出的驱动马达31的转速相应的驱动电流输出给驱动马达31。作为驱动马达31的转速控制，在本实施方式中，能使用PWM(Pulse Width Modulation：脉冲宽度调制)控制。这种情况下，与占空比相应的驱动电流即电力被提供给驱动马达31。温度传感器103b检测驱动电路103a的温度K2(以下称为“驱动器温度K2”)，将相当于检测出的驱动器温度K2的温度信号输出给控制部101。当驱动马达31的线圈35a的温度上升时，驱动驱动马达31的驱动电路103a的温度也上升。即，驱动器温度K2与驱动马达31的线圈35a的温度相关。需要说明的是，温度传感器103b相当于本发明的线圈温度传感器，驱动器温度K2相当于本发明的线圈温度。
离合器驱动部104根据从控制部101输出的控制信号，驱动传递机构部32的离合器机构32a。供水驱动部105根据来自控制部101的控制信号，驱动供水装置60的供水阀62。排水驱动部106根据来自控制部101的控制信号，驱动排水阀40。
风扇驱动部107根据从控制部101输出的控制信号，驱动烘干装置50的鼓风扇52。加热器驱动部108根据从控制部101输出的控制信号，驱动烘干装置50的加热器53。
温度传感器109例如是热敏电阻，配置于基板110，检测基板110的周围的温度K1(以下称为“基板周围温度K1”)。基板周围温度K1是与驱动马达31周围的温度大致相同的温度即相关的温度。需要说明的是，温度传感器109相当于本发明的周围温度传感器，基板周围温度K1相当于本发明的周围温度。
存储部102包括EEPROM、RAM等。存储部102存储有用于执行各种运转 模式的洗涤运转、洗涤烘干运转以及烘干运转的程序。此外，存储部102中存储有用于这些洗涤运转、洗涤烘干运转以及烘干运转的各种运转条件。
控制部101根据存储于存储部102的程序，对显示部92、马达驱动部103、离合器驱动部104、供水驱动部105、排水驱动部106、风扇驱动部107以及加热器驱动部108等进行控制。
在全自动洗干一体机1中，进行各种运转模式的洗涤运转、洗涤烘干运转或烘干运转。洗涤运转是仅进行洗涤的运转，按顺序执行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。洗涤烘干运转是连续进行洗涤到烘干的运转，在最终脱水过程之后接着执行烘干过程。烘干运转是仅进行烘干的运转，仅执行烘干过程。
在清洗过程和漂洗过程中，在洗涤脱水桶24内蓄有水的状态下，波轮26在间或停止的状态下向右方向和左方向交替旋转。洗涤脱水桶24内的洗涤物通过因波轮26的旋转而产生的水流等的作用被清洗或者漂洗。需要说明的是，在漂洗过程中，根据洗涤模式进行蓄水漂洗或注水漂洗。
在中间脱水过程和最终脱水过程中，洗涤脱水桶24和波轮26成为一体高速旋转。洗涤物通过洗涤脱水桶24中产生的离心力的作用而被脱水。
烘干过程中，首先进行内部空气循环烘干过程，接着进行外部空气导入烘干过程。内部空气循环烘干过程中，烘干装置50进行循环烘干动作，由此暖风在循环风路50a与外桶20之间循环。通过烘干风的循环，洗涤脱水桶24内的温度迅速上升。波轮26进行旋转，洗涤物一边被搅拌一边被循环的暖风烘干。当洗涤脱水桶24内的温度继续上升，水分从洗涤物蒸发而使得暖风中含有大量水分时，切换为外部空气导入烘干过程。外部空气导入烘干过程中，通过烘干装置50进行排风烘干动作，向循环风路50a导入外部空气，并且从循环风路50a排出一部分循环的暖风。由于从洗涤物蒸发的水分有效地从外桶20内排出到箱体10外，外桶20内变得容易除湿，因此促进了洗涤物的烘干。
另外，在洗涤运转和洗涤烘干运转中，在清洗过程之前，执行运转条件设定过程。
图4是用于对本实施方式的为了运转条件设定过程而存储于存储部102的 数据进行说明的图。
如图4所示，存储部102中存储有第一负荷量-水位表、第二负荷量-水位表以及第三负荷量-水位表。这些负荷量-水位表是用于根据洗涤物的负荷量来设定作为运转条件之一的洗涤脱水桶24内的水位的表。在第一负荷量-水位表中，与同一负荷量对应的水位比第二负荷量-水位表低，在第二负荷量-水位表中，与同一负荷量对应的水位比第三负荷量-水位表低。在运转条件设定过程中，使用这三个负荷量-水位表中的任意一个来进行清洗过程中的水位设定。
此外，在存储部102中，作为各种运转条件的一部分，存储有在运转条件设定过程中设定的清洗过程中的浸泡放置时间、PWM控制的占空比以及马达断开时间。浸泡放置时间是指驱动马达31工作而使波轮26不旋转，洗涤物浸泡放置在水中的时间。本实施方式中，在洗涤脱水桶24内的水位达到设定水位之后，在波轮26开始旋转之前，洗涤物被浸泡放置在水中。作为浸泡放置时间，存储有0分钟、T1分钟、比T1分钟的值大的T2分钟这三种值。占空比和马达断开时间是为了使波轮26向左右方向旋转而使驱动马达31间歇工作时的驱动马达31的接通时的占空比和驱动马达31的断开时间。作为占空比，存储有R1％、比R1％小的R2％、比R2％小的R3％这三个值。此外，作为马达断开时间，存储有t1秒、比t1秒大的t2秒、比t2秒大的t3秒这三个值。
图5是表示本实施方式的运转条件设定过程中的控制处理的流程图。
当洗涤运转或洗涤烘干运转开始时，首先进行运转条件设定过程。控制部101从温度传感器109获取基板周围温度K1(S101)，从温度传感器103b获取驱动器温度K2(S102)。然后，控制部101计算出驱动器温度K2与基板周围温度K1的温度差K3(S103)。
接着，控制部101对投入洗涤脱水桶24内的洗涤物的负荷量进行判定(S104)。例如，控制部101在洗涤脱水桶24内没有水的状态下使驱动马达31工作而使波轮26旋转，根据驱动马达31的到达转速、惯性旋转量等来检测此时施加给波轮26的负荷的大小，根据检测结果判定负荷量。
接着，控制部101判定温度差K3是否小于阈值M1(S105)。在上次运转结束之后经过了足够长的时间之后开始本次运转的情况下，驱动马达31的线圈 35a的温度已经足够低，同样，驱动器温度K2也足够低。因此，这种情况下，由于驱动器温度K2接近基板周围温度K1，因此温度差K3变小，其结果是，温度差K3变得比阈值M1小。
在温度差K3小于阈值M1的情况下(S105：是)，控制部101参照第一负荷量-水位表，根据在S104中判定出的负荷量，设定洗涤脱水桶24内的水位(S106)。此外，控制部101将浸泡放置时间设定为0分钟，即，采用洗涤物不浸泡放置在水中的设定(S107)。进而，控制部101将占空比设定为R1％(S108)，将断开时间设定为t1秒(S109)。
另一方面，在上次运转结束之后的短时间内开始本次运转的情况下，即连续进行运转的情况下，驱动马达31的线圈35a的温度还不够低，同样，驱动器温度K2也不够低。因此，这种情况下，由于驱动器温度K2与基板周围温度K1有差距，因此温度差K3变大，其结果是，温度差K3为阈值M1以上。
在温度差K3为阈值M1以上的情况下(S105：否)，控制部101判定基板周围温度K1是否小于阈值M2(S110)。在全自动洗干一体机1的设置环境的温度不高，驱动马达31周围的温度不高的情况下，基板周围温度K1也不会变高，因此基板周围温度K1变得比阈值M2小。
在基板周围温度K1小于阈值M2的情况下(S110：是)，控制部101参照第二负荷量-水位表，根据在S104中判定出的负荷量，设定洗涤脱水桶24内的水位(S111)。此外，控制部101采用洗涤物浸泡放置在水中的设定，将浸泡放置时间设定为T1分钟(S112)。进而，控制部101将占空比设定为比R1％小的R2％(S113)，将断开时间设定为比t1秒长的t2秒(S114)。
在夏季等情况下，全自动洗干一体机1的设置环境的温度可能会变高，驱动马达31周围的温度可能会变高。这样一来，基板周围温度K1也会变高，基板周围温度K1变为阈值M2以上。
在基板周围温度K1为阈值M2以上的情况下(S110：否)，控制部101参照第三负荷量-水位表，根据在S104中判定出的负荷量，设定洗涤脱水桶24内的水位(S115)。此外，控制部101采用洗涤物浸泡放置在水中的设定，将浸泡放置时间设定为比T1分钟长的T2分钟(S116)。进而，控制部101将占空 比设定为比R2％小的R3％(S117)，将断开时间设定为比t2秒长的t3秒(S118)。
需要说明的是，马达接通时间与温度差K3和基板周围温度K1无关，为预先设定的固定时间。因此，马达接通时间设定得越长，则驱动马达31的间歇工作中的马达断开时间的比例设定得越大。相反地，马达断开时间设定得越短，则马达接通时间的比例设定得越大。
这样一来，当设定了水位、浸泡放置时间、占空比以及马达断开时间时，控制部101计算出运转时间，以计算出的运转时间来作为运转剩余时间，显示于显示部92的剩余时间显示部(S119)。运转剩余时间根据与负荷量相应地设定的水位、浸泡放置时间等运转条件而变动。显示于剩余时间显示部的运转剩余时间随着洗涤运转的进行而减少。当运转剩余时间的显示被执行时，运转条件设定处理结束，移至清洗过程。
图6是表示本实施方式的清洗过程中的控制处理的流程图。
当清洗过程开始时，控制部101打开供水阀62向外桶20内即洗涤脱水桶24内进行供水(S201)。在该供水时，投入到供水装置60的洗涤剂容器的洗涤剂与水混合，被供给至洗涤脱水桶24。由此，洗涤脱水桶24内的水变成洗涤剂水。
控制部101判定洗涤脱水桶24内的水位是否达到了运转条件设定处理的S106、S111或S115中设定的设定水位(S202)。当洗涤脱水桶24内的水位为设定水位时(S202：是)，控制部101关闭供水阀62，停止供水(S203)。
接着，控制部101判定在供水停止后是否经过了浸泡放置时间(S204)。在运转条件设定处理的S107中浸泡放置时间被设定为0的情况下，直接判定为经过了浸泡放置时间。这种情况下，实质上，洗涤物没有浸泡放置在水中。另一方面，在运转条件设定处理的S112或S115中浸泡放置时间被设定为T1分钟或T2分钟的情况下，当经过了T1分钟或T2分钟时，判定为经过了浸泡放置时间。
当经过了浸泡放置时间时(S204：是)，控制部101开始驱动马达31的接通/断开控制，使波轮26以间或停止的方式向右方向和左方向交替旋转(S205)。这时，启动驱动马达31即波轮26的旋转时的PWM控制的占空比采用运转条件 设定处理的S108中设定的R1％、S113中设定的R2％或S117中设定的R3％。此外，马达断开时间采用运转条件设定处理的S109中设定的t1秒、S114中设定的t2秒或S118中设定的t3秒。控制部101判定波轮26开始旋转之后是否经过了清洗时间(S206)。清洗时间与温度差K3和基板周围温度K1无关，为预先设定的固定时间。当经过了清洗时间时(S206：是)，控制部101使驱动马达31停止，使波轮26停止(S207)。然后，控制部101打开排水阀40，从外桶20即洗涤脱水桶24进行排水(S208)。当排水完成时，清洗过程结束，移至中间脱水过程。排水阀40保持打开状态。
这样，在本实施方式中，在本次运转开始时驱动马达31的线圈35a的温度已经足够低，温度差K3小于阈值M1的情况下，在清洗过程中，使用第一负荷量-水位表来进行水位的设定，因此对于相同的负荷量，洗涤脱水桶24的水位变低。此外，由于浸泡放置时间为0，因此在使波轮26旋转之前洗涤物不会浸泡放置在水中。进而，通过将PWM控制的占空比设为R1％这样大的值，提供给驱动马达31的电力变大。进而，通过使马达断开时间设为t1秒这样小的值，马达断开时间的比例变小，相应地，马达接通时间的比例变大。
驱动马达31受到接通/断开控制，在波轮26以间或停止的方式向右方向和左方向交替旋转时，当对于相同的负荷量水位低时，洗涤物靠近波轮26，因此，容易对洗涤物作用强水流或洗涤物容易被波轮26摩擦，施加给洗涤物的机械力变大。此外，当提供给驱动马达31的电力变大时，驱动马达31的转矩变大，因此，容易使波轮26的旋转的启动提前或容易使转速变高，施加给洗涤物的机械力变大。进而，当马达接通时间的比例变大时，波轮26的旋转时间变长，向洗涤物施加机械力的时间变长。由此，洗涤物被很好地清洗，因此，确保了高洗净力。
此外，由于在使波轮26旋转之前洗涤物没有被浸泡放置在水中，因此，清洗过程中的运转时间不会延长。
另一方面，在本次运转开始时驱动马达31的线圈35a的温度不怎么低，温度差K3为阈值M1以上的情况下，在清洗过程中，为了使用第二负荷量-水位表或第三负荷量-水位表来进行水位的设定，对于相同的负荷量，洗涤脱水桶24的水位变高。此外，存在T1分钟或T2分钟的浸泡放置时间，在使波轮26旋转 之前洗涤物被浸泡放置在水中。进而，通过将PWM控制的占空比设为R2％或R3％这样小的值，提供给驱动马达31的电力变小。进而，通过将马达断开时间设为t2秒或t3秒这样大的值，马达断开时间的比例变大。
驱动马达31受到接通/断开控制，在波轮26以间或停止的方式向右方向和左方向交替旋转时，当对于相同的负荷量水位高时，洗涤物远离波轮26，因此，波轮26受到的来自洗涤物的负荷变小，对驱动马达31的负荷也变小。因此，线圈35a的温度不容易上升。此外，当提供给驱动马达31的电力变小时，进而，当马达断开时间的比例变大时，线圈35a的温度不容易上升。进而，线圈35a能在洗涤物被浸泡放置的期间冷却。由此，即使在运转开始时驱动马达31的线圈35a的温度还不怎么低，也能防止线圈35a的温度超过法律等规定的上限温度。此外，通过将洗涤物浸泡放置在含有洗涤剂的水中，附着于洗涤物的污垢容易分解，洗净力提高。
进而，在温度差K3为阈值M1以上的情况下，驱动马达31周围的温度高，当基板周围温度K1为阈值M2以上时，在清洗过程中，通过使用第三负荷量-水位表来使洗涤脱水桶24的水位进一步升高，浸泡放置时间为比T1分钟更长的T2分钟，占空比为小于R2％的R3％，马达断开时间为比t2秒更长的t3秒。由此，即使驱动马达31周围的温度高，线圈35a的温度也不容易上升，因此，能进一步防止线圈35a的温度超过上限温度。
＜实施方式的效果＞
根据本实施方式，根据在洗涤脱水桶24内蓄有水的状态下在驱动马达31工作之前检测出的与线圈35a的温度相关的驱动器温度K2和与驱动马达31周围的温度相关的基板周围温度K1的温度差K3，设定该次洗涤运转中的运转条件。由此，当线圈35a的温度低且与上限温度差距大时，线圈35a的温度可以容易上升，因此，能设定通过驱动马达31的工作来对洗涤物施加大的机械力或较长时间地施加机械力这样的运转条件，能确保高洗净力。另一方面，当线圈35a的温度高且与上限温度差距小时，可以设定通过驱动马达31的工作来对洗涤物施加小的机械力或较短时间地施加机械力这样的运转条件，以使线圈35a的温度不容易上升，能能防止线圈35a的温度超过上限温度。
此外，根据本实施方式，当线圈35a的温度低时，对于相同的负荷量，洗 涤脱水桶24的水位会变低，因此，通过驱动马达31的工作而施加给洗涤物的机械力变大。由此，能确保高洗净力。另一方面，当线圈35a的温度高时，对于相同的负荷量，洗涤脱水桶24的水位会变高，因此，波轮26受到的来自洗涤物的负荷变小，对驱动马达31的负荷也变小。由此，线圈35a的温度不容易上升，因此，能防止线圈35a的温度超过上限温度。
进而，根据本实施方式，当线圈35a的温度低时，不存在浸泡放置时间，因此运转时间不容易延长。另一方面，当线圈35a的温度高时，存在浸泡放置时间，因此线圈35a容易在洗涤物被浸泡放置在水中的期间冷却。由此，线圈35a的温度不容易上升，因此，能防止线圈35a的温度超过上限温度。
进而，根据本实施方式，当线圈35a的温度低时，提供给驱动马达31的电力变大，因此，通过驱动马达31的工作而施加给洗涤物的机械力变大。由此，能确保高洗净力。另一方面，当线圈35a的温度高时，提供给驱动马达31的电力变小，因此，线圈35a的温度不容易上升。由此，能防止线圈35a的温度超过上限温度。
进而，根据上述实施方式，当线圈35a的温度低时，使驱动马达31间歇工作时的马达断开时间的比例变小，相应地，马达接通时间的比例变大，因此，通过驱动马达31的工作来对洗涤物施加机械力的时间变长。由此，能确保高洗净力。另一方面，当线圈35a的温度高时，马达断开时间的比例变大，因此，线圈35a的温度不容易上升。由此，能防止线圈35a的温度超过上限温度。
进而，根据本实施方式，能设定在驱动马达31周围的温度高且线圈35a的温度容易上升时，通过驱动马达31的工作来对洗涤物施加较小的机械力或较短时间地施加机械力这样的运转条件。具体而言，能增高洗涤脱水桶24的水位，能延长浸泡放置时间，能减小提供给驱动马达31的电力，能增大使驱动马达31间歇工作时的马达断开时间的比例。由此，能进一步防止线圈35a的温度超过上限温度。
需要说明的是，在像以往那样采用当随着洗涤运转中的驱动马达31的工作而使线圈35a的温度达到规定温度以上时使驱动马达31停止的结构情况下，可能会由于洗涤运转的中断而导致运转剩余时间大幅紊乱。与此相对，在本实施方式中，不会使运转剩余时间大幅紊乱。
以上，对本发明的实施方式进行了说明，但本发明不受上述实施方式等的任何限制，此外，本发明的实施方式也可以进行上述以外的各种变形。
＜变形例1＞
图7是变形例1的全自动洗干一体机1的侧剖图。
在上述实施方式中，在马达驱动部103设置有温度传感器103b，通过温度传感器103b来检测与驱动马达31的线圈35a的温度相关的驱动电路103a的温度。此外，在基板110设置有温度传感器109，通过温度传感器109来检测与驱动马达31周围的温度相关的基板110周围的温度。
相对于此，本变形例中，如图7所示，在驱动马达31的定子35设置有温度传感器81。温度传感器81检测定子35的线圈35a的温度。此外，在驱动马达31的周围设置有温度传感器82。温度传感器82检测驱动马达31周围的温度。温度传感器81相当于本发明的线圈温度传感器，温度传感器82相当于本发明的周围温度传感器。
在运转条件设定过程中，在S103中计算出由温度传感器81检测出的线圈35a的温度与由温度传感器82检测出的周围的温度的温度差，在S105中，对计算出的温度差和与该温度差对应的阈值进行比较。此外，在S110中，对由温度传感器82检测出的周围的温度和与该周围温度对应的阈值进行比较。
＜其他变形例＞
上述实施方式中，清洗过程之外的过程的运转条件不根据温度差K3和基板周围温度K1来设定。但是，清洗过程之外的过程的运转条件也可以根据温度差K3和基板周围温度K1来设定。例如，漂洗过程中的蓄水漂洗时的洗涤脱水桶24内的水位、使波轮26旋转时的占空比以及马达断开时间也可以与清洗过程同样地根据温度差K3和基板周围温度K1来设定。进而，中间脱水过程和最终脱水过程中的脱水转速、脱水时间等也可以根据温度差K3和基板周围温度K1来设定。这种情况下，当温度差K3小于阈值M1时，脱水转速比温度差K3不小于阈值M1时高，脱水时间被延长。此外，当基板周围温度K1小于阈值M2时，脱水转速比基板周围温度K1不小于阈值M2时高，脱水时间被延长。
此外，上述实施方式中，在运转条件设定过程中，为了判定驱动马达31的 线圈35a的温度降低情况，在S103中计算驱动器温度K2与基板周围温度K1的温度差K3，在S105中将温度差K3和与该温度差K3对应的阈值M1进行比较。但是，也可以不执行S103的处理，而是在S105中对驱动器温度K2和与该驱动器温度K2对应的阈值进行比较。
进而，上述实施方式中，马达接通时间的值被固定，马达断开时间的值被改变，以便根据温度差K3和基板周围温度K1来改变驱动马达31间歇工作时的马达断开时间的比例也就是马达接通时间的比例。但是，也可以是，马达断开时间的值被固定，马达接通时间的值被改变。
进而，在上述实施方式中，无论温度差K3和基板周围温度K1如何，都将驱动马达31间歇工作时的马达接通时间和马达断开时间设为固定，取而代之，也可以根据温度差K3和基板周围温度K1来改变清洗时间。这种情况下，在温度差K3小于阈值M1的情况下，清洗时间被设定为比温度差K3为阈值M1以上且基板周围温度K1小于阈值M2时长的时间，在基板周围温度K1小于阈值M2的情况下，清洗时间被设定为比基板周围温度K1为阈值M2以上时长的时间。
进而，上述实施方式中，在温度差K3小于阈值M1的情况下，在S107中浸泡放置时间被设为0，即，不设置浸泡放置时间。但是，在温度差K3小于阈值M1的情况下，在S107中也可以将浸泡放置时间设定为比温度差K3为阈值M1以上且基板周围温度K1小于阈值M2时的浸泡放置时间短的时间。
进而，上述实施方式中，在洗涤脱水桶24内的水位达到设定水位之后，在波轮26开始旋转之前，洗涤物在水中浸泡放置了浸泡放置时间。但是，也可以是，在波轮26开始旋转之后暂时中断，在将洗涤物在水中浸泡放置了浸泡放置时间之后恢复旋转。
进而，上述实施方式中，使用了对于相同的负荷量而言使洗涤脱水桶24内的水位不同的三个负荷量-水位表。但是，也可以使用一个负荷量-水位表，取而代之，在S106、S111以及S115中，根据温度差K3和基板周围温度K1来设定追加的水位或水量。这种情况下，在温度差K3小于阈值M1的情况下，追加的水位或水量被设定为比温度差K3为阈值M1以上且基板周围温度K1小于阈值M2时少，在基板周围温度K1小于阈值M2的情况下，追加的水位或水量被 设定为比基板周围温度K1为阈值M2以上时少。
进而，上述实施方式中，示出了将本发明应用于搭载有衣物烘干功能的全自动洗干一体机1的例子。但是，本发明也能应用于不搭载衣物烘干功能的全自动洗衣机。此外，本发明也能应用于在外桶内配置有构成洗涤筒的横轴型滚筒的滚筒式洗衣机和在滚筒式洗衣机中搭载了衣物的烘干功能的滚筒式洗干一体机。需要说明的是，在本发明应用于滚筒式洗衣机或滚筒式洗干一体机的情况下，不进行与S106、S111以及S115的基于温度差K3和基板周围温度K1的水位设定。此外，S108、S113或S117中设定的占空比和S109、S114或S118中设定的马达断开时间是使驱动马达工作而使滚筒以间或停止的方式向右方向和左方向旋转时的时间。
除此之外，本发明的实施方式可以在技术方案所示的技术思想的范围内适当地进行各种变形。
