洗衣机 技术领域
本发明涉及例如进行洗涤过程以及漂洗过程的立式洗衣机。
背景技术
有一种立式洗衣机使旋转翼在洗涤脱水桶的底部被旋转驱动，并且在洗涤脱水桶的底壁与旋转翼之间自由旋转地配置有抽水翼(参照专利文献1)。在抽水翼的上表面设置有外圈齿轮，在与其对置的旋转翼的下表面，分别自由旋转地设置有与抽水翼的外圈齿轮啮合的多个行星齿轮。配置成在洗涤脱水桶的底部固定有太阳齿轮，行星齿轮与太阳齿轮的外围啮合，绕太阳齿轮的周围旋转。
洗涤、漂洗时，通过驱动马达使旋转翼正转、反转，从而通过由设置于旋转翼的搅拌翼部产生的搅拌水流来清洗洗涤脱水桶内的衣物。同时，旋转翼的旋转变成一体地设置于旋转翼的背面的行星齿轮的旋转，绕固定于洗涤脱水桶的太阳齿轮的外围旋转的同时，向设置于抽水翼的外圈齿轮传递旋转。
专利文献1的立式洗衣机中，因为在洗涤过程中旋转翼以及抽水翼双方都被驱动，所以洗涤脱水桶内的洗涤物通过旋转翼旋转所产生的摩擦而被清洗，在清洗易损的洗涤物的情况下，存在洗涤物会因旋转翼旋转所产生的摩擦而受损的问题。

具体实施方式
以下，参照附图对本发明的实施方式的立式洗衣机1进行说明。图1是本发明的实施方式的立式洗衣机1的示意性剖面图。
立式洗衣机1(以下，有时称为洗衣机1)具有作为洗衣机主体的箱体(未图示)，在箱体的内部，有底圆筒形状的外桶2由未图示的多根吊棒悬吊支承。
外桶2一体地具有上下方向延伸的圆筒状的侧壁7、和堵住侧壁7的下端的底壁8。外桶2的上端通过侧壁7的上端缘而形成有开口2a。在底壁8的中心位置形成有贯通孔10。洗涤液(混有洗涤剂的水或淡水)从底壁8侧蓄于外桶2。
洗涤脱水桶3收容在外桶2内，并收容洗涤物。洗涤脱水桶3一体地具有上下延伸的圆筒状的侧壁11、和堵住侧壁11的下端的底部12。洗涤脱水桶3的上端通过侧壁11的上端缘而形成有开口3a。
洗涤脱水桶3兼作脱水桶，具有在其周围形成的许多通水孔，以固定在其底部12的支承轴16为中心被自由旋转地轴支承。洗涤脱水桶3的底部12具有上侧的第一底壁17和下侧的第二底壁18，在第一底壁17与第二底壁18之间，形成有空间12a。
第一底壁17形成为环状，与洗涤脱水桶3的侧壁11的下端部连接。第一底壁17中存在不与洗涤脱水桶3的底部12连接的部分，在该部分连结有上下延伸的罩20。
罩20以与侧壁11对置的状态连接，并沿侧壁11向上方延伸。罩20与侧壁11成为一体，构成管状的抽水路21。在抽水路21的下端，设置有与空间12a连通的摄入口22，在抽水路21的上端，设置有与洗涤脱水桶3内连通的排出口20a。
在洗涤脱水桶3的底部12设置有旋转翼5。旋转翼5通过旋转来搅拌洗涤脱水桶3内的洗涤物。
在洗涤脱水桶3的底部12与旋转翼5之间的空间12a，设置有抽水翼6。抽水翼6通过旋转而将洗涤脱水桶3内的洗涤液从洗涤脱水桶3的底部12送入抽水路21。
抽水翼6设置为以支承轴16的旋转轴6a为中心自由旋转，旋转翼5设置为以嵌插至旋转轴6a的旋转轴5a为中心自由旋转。
洗涤脱水桶3具有分别与抽水路21和洗涤脱水桶3内连通的三个排出口 20a。三个排出口20a以俯视时相隔大致120度的方式配置。图2是从洗涤脱水桶3的内侧分别观察三个排出口20a的图，但是相互配置于不同的高度。由此，本实施方式的立式洗衣机1中，无论洗涤脱水桶3内的洗涤物的量如何，都会在洗涤脱水桶3内产生水流。
关于对洗涤脱水桶3、旋转翼5以及抽水翼6进行旋转驱动的驱动机构30，基于图3进行说明。图3表示洗衣机1的驱动机构30的概要结构。
驱动机构30具有马达31和离合器装置32a、32b、32c，通过马达31所产生的驱动力，分别对洗涤脱水桶3、旋转翼5以及抽水翼6进行旋转驱动。
具体而言，马达31经由离合器装置32a、32b、32c连接至与洗涤脱水桶3连接的支承轴16、与旋转翼5连接的旋转轴5a以及与抽水翼6连接的旋转轴6a。离合器装置32a、32b、32c是洗衣机1的一部分，能使用公知的结构。
离合器装置32a、32b、32c能从其马达驱动轴接收马达31所产生的驱动力，并将该驱动力向与洗涤脱水桶3连接的支承轴16、与旋转翼5连接的旋转轴5a、与抽水翼6连接的旋转轴6a传递或切断。
本实施方式中，对于离合器装置32a、32b、32c的状态，将使马达31的驱动力向支承轴16、旋转轴5a以及旋转轴6a传递的状态设为接通状态，将使马达31的驱动力不向支承轴16、旋转轴5a以及旋转轴6a传递的状态设为断开状态。
因此，洗衣机1中，能通过分别独立地控制离合器装置32a、32b、32c，从而分别独立地驱动洗涤脱水桶3、旋转翼5、抽水翼6。洗衣机1如后述的图4所示，在洗涤过程或漂洗过程中，在停止了洗涤脱水桶3的状态下，能进行仅对抽水翼6进行旋转驱动的第一运转、对抽水翼6以及旋转翼5进行旋转驱动的第二运转、以及仅对旋转翼5进行旋转驱动的第三运转。
第一运转是在洗涤过程中对抽水翼6进行旋转驱动且不对旋转翼5进行旋转驱动的运转，是通过从抽水路21的排出口20a排出的流水对洗涤物进行水流(轻柔)清洗的运转。因此，第一运转中，洗涤脱水桶3内的洗涤物不会因旋转翼5旋转所产生的摩擦而受损。
第二运转是在洗涤过程中对抽水翼6进行旋转驱动且对旋转翼5进行旋转 驱动的运转，是通过从洗涤脱水桶3的排出口20a排出的流水对洗涤物进行清洗，并且搅拌洗涤脱水桶3内的洗涤物进行清洗的运转。因此，第二运转中，能迅速地清洗大量的污垢。
第三运转是在洗涤过程中对旋转翼5进行旋转驱动且不对抽水翼6进行旋转驱动的运转，是通过旋转翼5搅拌洗涤脱水桶3内的洗涤物而进行清洗的运转。因此，在因洗涤脱水桶3内的洗涤物的量少而不驱动抽水翼6也能清洗的情况下，不对抽水翼6进行旋转驱动，因此与驱动旋转翼5以及抽水翼6双方的情况相比，能以节能的方式进行清洗。
图5是本实施方式的洗衣机1的控制框图。洗衣机1的控制部50如图5所示，例如由微型计算机等构成，并具备：CPU、储存有控制洗衣机1的动作的程序的ROM、以及临时存储执行上述程序时所用的数据等的RAM。洗衣机1的运转动作由该控制部50控制。
本实施方式的立式洗衣机1中，控制部50以执行洗涤过程、漂洗过程以及脱水工程的各项运转的方式控制马达31。
控制部50具有负荷量检测部51和旋转驱动控制部52。在控制部50，连接有马达31和离合器装置32a、32b、32c。
负荷量检测部51检测与洗涤脱水桶3内的洗涤物的量对应的负荷量。本实施方式中，负荷量以洗涤物的重量表示。洗衣机1中，在洗涤动作开始时，使马达31短时间工作从而旋转驱动旋转翼5，之后，当关停马达31时，旋转翼5惯性旋转。
负荷量检测部51在该惯性旋转期间，对与马达31的旋转同步的脉冲信号进行计数，并基于该计数值来检测负荷量。需要说明的是，因为负荷量越大对旋转翼5的旋转的阻力越大，所以惯性旋转的持续时间变短。
旋转驱动控制部52在洗涤过程或漂洗过程中，在洗涤脱水桶3停止的状态下，以执行仅对抽水翼6进行旋转驱动的第一运转、对抽水翼6以及旋转翼5进行旋转驱动的第二运转、仅对旋转翼5进行旋转驱动的第三运转中的任一运转的方式，控制马达31和离合器装置32a、32b、32c。
本实施方式的立式洗衣机1具备：外桶2；洗涤脱水桶3，可旋转地设置于 外桶2内并收容洗涤物；抽水路21，设置于洗涤脱水桶3，用于从洗涤脱水桶3的底部12抽取洗涤脱水桶3内的洗涤液并使其回到洗涤脱水桶3内；排出口20a，从抽水路21向洗涤脱水桶3内排出洗涤液；旋转翼5，设置于洗涤脱水桶3的底部12，通过旋转搅拌来洗涤脱水桶3内的洗涤物；抽水翼6，设置于洗涤脱水桶3的底壁与旋转翼5之间，通过旋转，将洗涤脱水桶3内的洗涤液从洗涤脱水桶3的底部12送入抽水路21；作为驱动单元的驱动机构30，能对洗涤脱水桶3、旋转翼5以及抽水翼6分别独立地进行旋转驱动；以及作为控制单元的旋转驱动控制部52，控制驱动机构30。
由此，本实施方式的立式洗衣机1中，能对洗涤脱水桶、旋转翼以及抽水翼分别独立地进行旋转驱动，能通过根据例如洗涤物的种类等而仅驱动抽水翼的清洗方法、仅驱动旋转翼的清洗方法、驱动旋转翼以及抽水翼双方的清洗方法等各种清洗方法清洗洗涤物。
本实施方式的立式洗衣机1中，能执行仅驱动抽水翼6的第一运转，并在洗涤过程中进行第一运转。
本实施方式的立式洗衣机1中，通过在洗涤过程中选择仅驱动抽水翼6的第一运转，从而对于易损的洗涤物，能不通过旋转翼5旋转所产生的摩擦来清洗，而通过从抽水路21的排出口20a排至洗涤脱水桶3内的洗涤液的水流来充分清洗。因此，能防止洗涤物在洗涤过程中受损，并且能得到适当的清洗效果。
对于洗衣机1的洗涤动作，基于图6进行说明。
<步骤S1>
步骤S1中，当使用者将洗涤物投入洗涤脱水桶3内，并进行适当的设定后按下开始键时，控制部50执行负荷量检测处理。控制部50根据该负荷量来确定为多个阶段设定的洗涤水位。
<步骤S2>
步骤S2中，确定洗涤水位并进行实质的清洗过程，为了开始洗涤过程，控制部50向洗涤脱水桶3内供水至规定水位，并通过使旋转翼5以规定速度单向或双向旋转来执行洗涤运转。当洗涤过程结束时，控制部50将洗涤脱水桶3内的水排出。
<步骤S3>
步骤S3中，控制部50向洗涤脱水桶3内提供规定量的水，与步骤S2的洗涤过程时相同，通过旋转旋转翼5来执行蓄水漂洗。当蓄水漂洗结束时，控制部50将洗涤脱水桶3内的水排出。
<步骤S4>
然后，在步骤S4中，控制部50通过使洗涤脱水桶3高速旋转而执行脱水。
本实施方式的洗衣机1中，能进行例如洗涤模式A、B、C、D的洗涤动作。
对于洗涤模式A的动作，基于图7进行说明。作为洗涤过程中的清洗方法，洗涤模式A是为了清洗易损的洗涤物而选择了水流清洗的模式。

对以下情况进行说明：图8的普通清洗中，在洗涤过程中，在洗涤脱水桶3停止的状态下，按顺序执行仅对抽水翼6进行旋转驱动的第一运转、对抽水翼6以及旋转翼5进行旋转驱动的第二运转、仅对旋转翼5进行旋转驱动的第三运转。

步骤S402中，控制部50向洗涤脱水桶3供水。当供水结束时，进入步骤S403。
<步骤S403>
步骤S403中，控制部50在作为洗涤脱水桶驱动用离合器的离合器装置32a处于断开状态的状态下，将作为抽水翼驱动用离合器的离合器装置32c切换至接通状态，并且将作为旋转翼驱动用离合器的离合器装置32b切换至断开状态。
<步骤S404>
步骤S404中，控制部50以700rpm对马达31进行旋转驱动。
<步骤S405>
步骤S405中，控制部50在使洗涤脱水桶3停止的状态下，通过仅对抽水翼6进行旋转驱动的第一运转来进行水流清洗。
<步骤S406>
步骤S406中，当水流清洗结束时，控制部50将洗涤脱水桶3内的水排出。
<步骤S407>
步骤S407中，控制部50向洗涤脱水桶3内进行漂洗用的供水。当供水结束时，进入步骤S408。
<步骤S408>
步骤S408中，控制部50在作为洗涤脱水桶驱动用离合器的离合器装置32a处于断开状态的状态下，将作为抽水翼驱动用离合器的离合器装置32c切换至断开状态，并且将作为旋转翼驱动用离合器的离合器装置32b切换至接通状态。
<步骤S409>
步骤S409中，控制部50以200rpm对马达31进行旋转驱动。
<步骤S410>
步骤S410中，控制部50在使洗涤脱水桶3停止的状态下，通过仅对旋转翼5进行旋转驱动的第三运转来进行漂洗。
本实施方式的立式洗衣机1中，在进行包括洗涤过程以及漂洗过程的洗涤动作的情况下，作为控制单元的旋转驱动控制部52在洗涤过程中进行仅驱动抽水翼6的第一运转，并且在漂洗过程中进行仅驱动旋转翼5的第三运转，第三运转中的旋转翼5的转速比第一运转中的抽水翼6的转速小。
由此，本实施方式的立式洗衣机1中，对于易损的洗涤物，通过在洗涤过程中由水流充分清洗并在漂洗过程中以低转速旋转旋转翼，从而确保漂洗性能，进而能防止洗涤物受损，并且能减少漂洗过程中的耗电。
以上，对本发明的实施方式进行了说明，但是各个部分的具体结构不仅局限于上述的实施方式。
例如，上述实施方式中，洗涤脱水桶3具有分别与抽水路21和洗涤脱水桶3内连通的三个排出口20a，但是排出口20a的数量、高度、配置不受此限。
