具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图22描述本申请一些实施例所述的电器设备的电机控制器、电器设备的电机装置和电器设备。
本申请第一方面的实施例提供的电器设备的电机控制器1，电器设备包括第一驱动电机2和第二驱动电机3。第一驱动电机2的运行功率大于第二驱动电机3的运行功率。第一驱动电机2与第二驱动电机3错开时间运行。换言之，第一驱动电机2与第二驱动电机3不同时运行。
具体地，如图5所示，电机控制器1包括：第一控制电路102和第二控制电路104。第一控制电路102与第一驱动电机2和第二驱动电机3电连接，用 于控制第一驱动电机2和第二驱动电机3运行。第二控制电路104与第二驱动电机3的绕组(32a、32b、32c)电连接，用于控制第二驱动电机3的绕组(32a、32b、32c)充当电抗器。
本申请第一方面的实施例提供的电器设备的电机控制器1，包括第一控制电路102和第二控制电路104，且第一控制电路102既与第一驱动电机2电连接，又与第二驱动电机3电连接，使得第一驱动电机2的电机控制器1具备三个控制功能，其中一个功能控制第一驱动电机2运行，另一个功能控制第二驱动电机3运行，还有一个功能控制第二驱动电机3的绕组(32a、32b、32c)充当电抗器。如此一来，当需要电抗器时，直接利用第二控制电路104使第二驱动电机3的绕组(32a、32b、32c)充当电抗器即可，从而省去了额外的电抗器，既简化了电器设备的结构，节省了整机内部的利用空间，能够提高电器设备的集成度，并减少安装工序，提升生产效率，有效减少电器设备的系统材料成本。
换言之，本方案将第一驱动电机2的控制电路和第二驱动电机3的控制电路集成在一起，则无需对第二驱动电机3额外设置控制器，从而提高了电器设备的集成度；还有利于第一驱动电机2和第二驱动电机3共用某些硬件结构(如共用整流电路)，这能够减少电器设备的元器件数量，简化电器设备的线路布局。同时，该电机控制器1还增设了第二控制电路104，使得第二驱动电机3的绕组(32a、32b、32c)可以充当电抗器，由此省去电器设备额外设置的电抗器，进一步减少了部件数量，简化了整机结构，节约了整机内部空间，既有利于降低成本，也有利于简化安装工序，提高生产效率。
值得说明的是，本申请中，第二驱动电机3的绕组的相数不局限于附图中的三相或两相，也可以为一相或四相或更多相。进一步地，第二驱动电机3的绕组接入电路中充当电抗器的具体相数也不受限制，比如三相绕组只有两相绕组接入电路充当电抗器，或者两相绕组全部接入电路充当电抗器都可以。只要第二驱动电机3有绕组接入电路充当电感，即可充当电抗器。
下面结合图1至图4介绍一些实施例。
实施例一
电机控制器1包括电源电路108，如图1所示。电源电路108用于连接外 部电源。第二控制电路104用于使第二驱动电机3的绕组(32a、32b、32c)选择性地接入电源电路108。
当电器设备运行主要功能时，第一驱动电机2运行，此时电机控制器1功率较大，一般需要进线电抗器；而当电器设备运行次要功能时，第二驱动电机3运行，此时控制器功率较小，一般不需要进线电抗器。因此，在电机控制器1上增设第二控制电路104，利用第二控制电路104将第二驱动电机3的绕组(32a、32b、32c)选择性地接入电源电路108，即可利用第二驱动电机3的绕组(32a、32b、32c)等效实现进线电抗器的功能。
这相当于将进线电抗器的功能集成在了电机控制器1中，从而省去了额外设置的进线电抗器，可以有效提高电器设备的集成度，提升生产效率，减少材料成本，提高电器设备内部空间的利用率，为优化电器设备内部布线设计以及结构设计带来便利。
当然，第二驱动电机3的绕组(32a、32b、32c)也可以一直接入电源电路108，即：并非选择性地接入电源电路108。这样，当第一驱动电机2运行而第二驱动电机3不运行时，第二驱动电机3的绕组(32a、32b、32c)充当进线电抗器；当第一驱动电机2电机运行而第二驱动电机3也运行时，第二驱动电机3的绕组(32a、32b、32c)既参与第二驱动电机3的正常电路以保证第二驱动电机3的正常运行，同时也接入了电源电路108，充当了进线电抗器；当第一驱动电机2不运行而第二驱动电机3运行时，第二驱动电机3的绕组(32a、32b、32c)只参与第二驱动电机3的正常电路，保证第二驱动电机3的正常运行。
进一步地，第一控制电路102与电源电路108电连接。
第二控制电路104与电源电路108电连接，第二控制电路104包括组件切换电路1042。组件切换电路1042包括连接线路1070和设在连接线路1070上的切换件1050。
连接线路1070将第二驱动电机3的绕组(32a、32b、32c)串联接入电源电路108。
切换件1050用于根据电器设备的状态控制连接线路1070的通断，以使第二驱动电机3的绕组(32a、32b、32c)选择性地串联接入电源电路108。
电机控制器1通过电源电路108来连接外部电源，保证电机控制器1的正常供电。同时，电源电路108、第一控制电路102和第二控制电路104集成在电机控制器1上，则第一控制电路102和第二控制电路104与电源电路108相距较近，便于布线设计，简化线路结构，提高电机控制器1的电路板10的集成度。电源电路108为第一控制电路102供电，保证第一控制电路102能够控制第一驱动电机2和第二驱动电机3正常运行。第二控制电路104通过组件切换电路1042实现控制功能，具体通过控制切换件1050闭合或断开来控制第二驱动电机3的绕组(32a、32b、32c)选择性地串联接入电源电路108。
当切换件1050导通连接线路1070，则第二驱动电机3的绕组(32a、32b、32c)通过连接线路1070串联接入电源电路108。当切换件1050断开连接线路1070时，则第二驱动电机3的绕组(32a、32b、32c)与电源电路108断开。本方案构思巧妙，且成本低，易于推广。
其中，组件切换电路1042具体用于：当电器设备处于第一驱动电机2运行对应的状态时，切换件1050控制连接线路1070处于导通状态，以使第二驱动电机3的绕组(32a、32b、32c)串联接入电源电路108。当电器设备处于第二驱动电机3运行对应的状态时，切换件1050控制连接线路1070处于断开状态，以使第二驱动电机3的绕组(32a、32b、32c)与所电源电路108断开。
对于具备第一驱动电机2和第二驱动电机3的电器设备而言，电器设备运行第二驱动电机3对应的功能时，控制器功率低无需进线电抗器，而电器设备运行第一驱动电机2对应的功能时，控制器功率高需要进线电抗器。因此，当电器设备整机处于第一驱动电机2运行对应的状态时，即第二驱动电机3不需要运行时，切换件1050控制连接线路1070处于导通状态，即可将第二驱动电机3的绕组(32a、32b、32c)串入电源电路108，充当电抗器的功能。而当整机处于第二驱动电机3运行对应的状态时，即第二驱动电机3需要运行时，则切换件1050控制连接线路1070处于断开状态，即可将第二驱动电机3的绕组(32a、32b、32c)切回到正常的电路中，保证第二驱动电机3及其驱动的部件的正常运行。
其中，切换件1050可以只有一种闭合状态，如单刀单掷开关，只控制一条线路的通断。切换件1050也可以具有多种闭合状态，如单刀双掷开关，通 过选择具体的闭合状态，来实现多条线路的选择性通断。
值得说明的是，电器设备200的运行模式以及运行模式的切换，一般写入计算机程序中，处理器执行计算机程序，控制各个硬件部件执行相应动作。因此，本方案中，切换件1050具体动作的时机也可以写入电器设备200的计算机程序中，与整机的状态保持吻合，实现自动切换。
比如：当电器设备200要运行第一驱动电机2运行对应的模式时，切换件1050提前设定时间(如3秒钟、5秒钟等)发生动作，导通连接线路1070，使第二驱动电机3的绕组(32a、32b、32c)串联接入电源电路108，保证后续第一驱动电机2即可正常运行。
当电器设备200要切换至第二驱动电机3运行对应的模式时，切换件1050提前设定时间(如3秒钟、5秒钟等)发生动作，断开连接线路1070，使第二驱动电机3的绕组(32a、32b、32c)与电源电路108断开，保证后续第二驱动电机3能够正常运行。
进一步地，如图1所示，第一控制电路102包括：第一逆变电路1026和第二逆变电路4。第一逆变电路1026与第一驱动电机2电连接。第二逆变电路4与第二驱动电机3电连接，且第二逆变电路4与第一逆变电路1026相并联。
第一控制电路102包括第一逆变电路1026和第二逆变电路4，且第一逆变电路1026和第二逆变电路4相并联，便于共用整流电路，则无需为第二驱动电机3额外设置整流电路，因而提高了电机控制器1的集成度，降低了产品成本。第一逆变电路1026能够将电压调整为适合第一驱动电机2运行的电压，第二逆变电路4能够将电压调整为适合第二驱动电机3运行的电压，从而保证第一驱动电机2和第二驱动电机3的正常运行。
当然，第一控制电路102还可以包括其他用于控制第一驱动电机2和第二驱动电机3运行的电路结构。
具体地，如图1所示，电源电路108包括：整流主电路1088和滤波电路1024。整流主电路1088用于连接外部电源。滤波电路1024连接整流主电路1088与第一控制电路102。
其中，整流主电路1088与滤波电路1024之间连接有直流母线1094，组 件切换电路1042接在直流母线1094上，以使第二驱动电机3的绕组(32a、32b、32c)串联在直流母线1094上。
本方案能够将第二驱动电机3的绕组(32a、32b、32c)串联在整流电路整流后的直流母线1094上，使得第二驱动电机3的绕组(32a、32b、32c)也能够串联在整流后的直流母线1094上，使得第二驱动电机3的绕组(32a、32b、32c)串入交流电源进线中，从而使得第二驱动电机3的绕组(32a、32b、32c)充当进线电抗器的功能。如此，便于技术人员根据电路板10的具体形状、尺寸、布局及电器设备的其他结构等因素进行合理设计，以优化电路板10的结构和性能。
更具体地，电源电路108包括整流主电路1088和滤波电路1024。整流主电路1088能够将交流电转换为直流电，这样即可利用交流电源为电机控制器1供电，便于电器设备利用常见的市政交流电等电源工作，提高电器设备的普适性。滤波电路1024滤去整流输出电压中的纹波，从而保证供给第一控制电路102的电压更加稳定，便于第一控制电路102根据第一驱动电机2和第二驱动电机3的运行需求提供所需的电能，满足第一驱动电机2和第二驱动电机3的运行需求。
同时，直流母线1094位于整流主电路1088与滤波电路1024之间，则组件切换电路1042可以接入整流主电路1088和滤波电路1024之间，防止第二驱动电机3的绕组(32a、32b、32c)串入后对滤波电路1024及后续第一控制电路102的运行造成影响。
进一步地，直流母线1094包括直流正母线1090。如图1所示，切换件1050接入直流正母线1090，用于控制直流正母线1090与第二驱动电机3的绕组(32a、32b、32c)导通或直接与滤波电路1024导通。
第二逆变电路4和第一逆变电路1026共用整流电路，则无需为第二驱动电机3额外设置整流电路，因而提高了电机控制器1的集成度，降低了产品成本。本方案具体利用一个切换件1050和一个连接线路1070实现了第二驱动电机3的绕组(32a、32b、32c)的选择性串入电源电路108，有利于降低成本。
具体地，组件切换电路1042可以接在直流正母线1090上。当整机处于第一驱动电机2运行对应的状态时，第二逆变电路4的IGBT 42全部断开(IGBT， Insulated Gate Bipolar Transistor，绝缘栅双极型晶体管，可以理解为开关元件)，切换件1050控制直流正母线1090与第二驱动电机3的绕组(32a、32b、32c)导通，则整流主电路1088、直流正母线1090、连接线路1070、第二驱动电机3的绕组(32a、32b、32c)的中性点、第二驱动电机3的绕组(32a、32b、32c)、第二逆变电路4的H桥的上管续流二极管44顺次导通，然后接第一逆变电路1026，即：实现了将第二驱动电机3的绕组(32a、32b、32c)接入直流正母线1090。当整机处于第二驱动电机3运行对应的状态时，切换件1050控制直流正母线1090与滤波电路1024直接连通，则第二驱动电机3的绕组(32a、32b、32c)与电源电路108之间断开，第二驱动电机3的绕组(32a、32b、32c)切回第二驱动电机3的正常电路中，保证第二驱动电机3及其驱动的部件的正常运行。
更具体地，第二驱动电机3为三相电机，包括三组绕组(32a、32b、32c)。第二逆变电路4通过三相桥接6个IGBT 42(开关元件)而构成，在各IGBT 42的集电极与发射极之间连接有续流二极管，即：上桥臂侧的三个上管续流二极管44和下桥臂侧的三个下管续流二极管46。第二逆变电路4的各相输出端子连接在第二驱动电机3的各相绕组上。第一逆变电路1026的构成以及与第一驱动电机2的绕组的连接方式与此相同，不再赘述。
切换件1050为单刀双掷开关，静触点连接直流正母线1090，两个动触点分别连接滤波电路1024和连接线路1070的一端，连接线路1070的另一端连接第二驱动电机3的绕组(32a、32b、32c)。第二逆变电路4的正负极分别与滤波电路1024滤波后的正负极相接。
当整机处于第一驱动电机2运行对应的状态时，切换件1050闭合至连接连接线路1070的动触点。
当整机处于第二驱动电机3运行对应的状态时，切换件1050闭合至连接滤波电路1024的动触点。
实施例二
与实施例一的区别在于：直流母线1094包括直流负母线1092。如图2所示，切换件1050接入直流负母线1092，用于控制直流负母线1092与第二驱动电机3的绕组(32a、32b、32c)导通或直接与滤波电路1024导通。
组件切换电路1042也可以接在直流负母线1092上。当整机处于第一驱动电机2运行对应的状态时，第二逆变电路4的IGBT 42全部断开，切换件1050控制直流负母线1092与第二驱动电机3的绕组(32a、32b、32c)导通，则滤波电路1024、第二逆变电路4上的H桥的下管续流二极管46、第二驱动电机3的绕组(32a、32b、32c)、第二驱动电机3的绕组(32a、32b、32c)的中性点、连接线路1070、直流负母线1092、整流主电路顺次导通，即：实现了将第二驱动电机3的绕组(32a、32b、32c)接入直流负母线1092。当整机处于第二驱动电机3运行对应的状态时，切换件1050控制直流负母线1092与滤波电路1024直接连通，则第二驱动电机3的绕组(32a、32b、32c)与电源电路之间断开，第二驱动电机3的绕组(32a、32b、32c)切回第二驱动电机3的正常电路中，保证第二驱动电机3及其驱动的部件的正常运行。
更具体地，第二驱动电机3为三相电机，包括三组绕组(32a、32b、32c)。第二逆变电路通过三相桥接6个IGBT 42(开关元件)而构成，在各IGBT 42的集电极与发射极之间连接有续流二极管，即：上桥臂侧的三个上管续流二极管44和下桥臂侧的三个下管续流二极管46。第二逆变电路4的各相输出端子连接在第二驱动电机的各相绕组上。
切换件1050为单刀双掷开关，静触点连接直流负母线1092，两个动触点分别连接滤波电路1024和连接线路1070的一端，连接线路1070的另一端连接第二驱动电机3的绕组(32a、32b、32c)。第二逆变电路4的正负极分别与滤波电路1024滤波后的正负极相接。
当整机处于第一驱动电机2运行对应的状态时，切换件1050闭合至连接连接线路1070的动触点。
当整机处于第二驱动电机3运行对应的状态时，切换件1050闭合至连接滤波电路1024的动触点。
实施例三

其工作原理与实施例一基本相同，在此不再赘述。
实施例四
如图4所示，与实施例二的区别在于：第二驱动电机3为两相电机，包括两组绕组(32a、32b)。第二逆变电路4通过两相桥接四个IGBT 42(开关元件)而构成，在各IGBT 42的集电极与发射极之间连接有续流二极管，即：上桥臂侧的两个上管续流二极管44和下桥臂侧的两个下管续流二极管46。第二逆变电路4的各相输出端子连接在第二驱动电机3的各相绕组(32a、32b)上。
其工作原理与实施例二基本相同，在此不再赘述。
本申请第二方面的实施例提供的电器设备200的电机控制器1，电器设备200包括第一驱动电机2和第二驱动电机3。第一驱动电机2的运行功率大于第二驱动电机3的运行功率。第一驱动电机2与第二驱动电机3错开时间运行。换言之，第一驱动电机2与第二驱动电机3不同时运行。
具体地，电机控制器1包括：第一控制电路102和第二控制电路104，如图16所示。第一控制电路102与第一驱动电机2电连接，用于控制第一驱动电机2运行。第二控制电路104与第二驱动电机3的绕组(32a、32b、32c)电连接，用于控制第二驱动电机3的绕组(32a、32b、32c)充当电抗器。
本申请第二方面的实施例提供的电器设备200的电机控制器1，包括第一控制电路102和第二控制电路104，使得第一驱动电机2的电机控制器1具备两个控制功能，其中一个功能控制第一驱动电机2运行，另一个控制功能控制第二驱动电机3的绕组(32a、32b、32c)充当电抗器。如此一来，当需要电抗器时，直接利用第二控制电路104使第二驱动电机3的绕组(32a、32b、32c)充当电抗器即可，从而省去了额外的电抗器，既简化了电器设备200的结构，节省了整机内部的利用空间，能够提高电器设备200的集成度，并减少安装工序，提升生产效率，有效减少电器设备200的系统材料成本。
其中，用于控制第二驱动电机3运行的控制电路，可以单独设置在其他控制器的电路板上，也可以部分集成该电机控制器1的电路板10上，也可以全部集成在该电机控制器1的电路板10上。
值得说明的是，对于具备第一驱动电机2和第二驱动电机3的电器设备 200而言，一般同时具备多种功能，第一驱动电机2驱动大部件运行，实现主要功能；第二驱动电机3驱动小部件运行，实现次要功能。因此，第一驱动电机2和第二驱动电机3一般不会同时运行。当电器设备200运行主要功能时，第一驱动电机2运行，此时电机控制器1功率较大，需要电抗器；而当电器设备200运行次要功能时，第二驱动电机3运行，此时控制器功率较小，一般不需要电抗器。因此，在第一驱动电机2的电机控制器1上增设第二控制电路104，通过第二控制电路104即可利用第二驱动电机3的绕组(32a、32b、32c)等效实现电抗器的功能。这相当于将电抗器的功能集成在了第一驱动电机2的电机控制器1中，从而省去了额外设置的电抗器，可以有效提高电器设备200的集成度，提升生产效率，减少材料成本，提高电器设备200内部空间的利用率，为优化电器设备200内部布线设计以及结构设计带来便利。
比如：对于具备滚筒电机和风机电机的洗衣机而言，一般同时具备洗涤功能和烘干功能，滚筒电机驱动滚筒运行，实现洗涤、脱水等功能，为主要功能；风机电机驱动风机运行，实现烘干功能，为次要功能。换言之，当洗衣机整机处于非烘干状态，滚筒电机驱动滚筒运行；当洗衣机整机处于烘干状态，风机电机驱动风机运行。因此，滚筒电机和风机电机一般不会同时运行。故而可以利用风机电机的绕组(32a、32b、32c)等效实现电抗器。
下面结合附图介绍一些实施例。
实施例五
电机控制器1包括电源电路108(如图6所示)，电源电路108用于连接外部电源。第二控制电路104用于使第二驱动电机3的绕组(32a、32b、32c)选择性地接入电源电路108。
当电器设备200运行主要功能时，第一驱动电机2运行，此时电机控制器1功率较大，一般需要进线电抗器；而当电器设备200运行次要功能时，第二驱动电机3运行，此时控制器功率较小，一般不需要进线电抗器。因此，在第一驱动电机2的电机控制器1上增设第二控制电路104，利用第二控制电路104将第二驱动电机3的绕组(32a、32b、32c)选择性地接入电源电路108，即可利用第二驱动电机3的绕组(32a、32b、32c)等效实现进线电抗器的功能。
这相当于将进线电抗器的功能集成在了第一驱动电机2的电机控制器1 中，从而省去了额外设置的进线电抗器，可以有效提高电器设备200的集成度，提升生产效率，减少材料成本，提高电器设备200内部空间的利用率，为优化电器设备200内部布线设计以及结构设计带来便利。
进一步地，第一控制电路102与电源电路108电连接。
第二控制电路104与电源电路108电连接。第二控制电路104包括组件切换电路1042。组件切换电路1042包括电连接部1046和设在电连接部1046上的切换组件1044，如图7所示。
电连接部1046将第二驱动电机3的绕组(32a、32b、32c)串联接入电源电路108。
切换组件1044用于根据电器设备200的状态控制电连接部1046的通断，以使第二驱动电机3的绕组(32a、32b、32c)选择性地串联接入电源电路108。
电机控制器1的电路板10通过电源电路108来连接外部电源，保证电路板10的正常供电。同时，电源电路108、第一控制电路102和第二控制电路104集成在电路板10上，则第一控制电路102、第二控制电路104与电源电路108相距较近，便于布线设计，简化线路结构，提高电路板10的集成度。电源电路108为第一控制电路102供电，保证第一控制电路102能够控制第一驱动电机2正常运行。第二控制电路104通过组件切换电路1042实现控制功能，具体通过控制切换组件1044闭合或断开来控制第二驱动电机3的绕组(32a、32b、32c)选择性地串联接入电源电路108。
当切换组件1044导通电连接部1046，则第二驱动电机3的绕组(32a、32b、32c)通过电连接部1046串联接入电源电路108。当切换组件1044断开电连接部1046时，则第二驱动电机3的绕组(32a、32b、32c)与电源电路108断开。本方案构思巧妙，且成本低，易于推广。
其中，组件切换电路1042具体用于：当电器设备200处于第一驱动电机2运行对应的状态时，切换组件1044控制电连接部1046处于导通状态，以使第二驱动电机3的绕组(32a、32b、32c)串联接入电源电路108。当电器设备200处于第二驱动电机3运行对应的状态时，切换组件1044控制电连接部1046处于断开状态，以使第二驱动电机3的绕组(32a、32b、32c)与所电源电路108断开。
如前所述，对于具备第一驱动电机2和第二驱动电机3的电器设备200而言，电器设备200运行第二驱动电机3对应的功能时，控制器功率低无需进线电抗器，而电器设备200运行第一驱动电机2对应的功能时，控制器功率高需要进线电抗器。因此，当电器设备200整机处于第一驱动电机2运行对应的状态时，即第二驱动电机3不需要运行时，切换组件1044控制电连接部1046处于导通状态，即可将第二驱动电机3的绕组(32a、32b、32c)串入电源电路108，充当电抗器的功能。而当整机处于第二驱动电机3运行对应的状态时，即第二驱动电机3需要运行时，则切换组件1044控制电连接部1046处于断开状态，即可将第二驱动电机3的绕组(32a、32b、32c)切回到正常的电路中，保证第二驱动电机3及其驱动的部件的正常运行。
值得说明的是，电器设备200的运行模式以及运行模式的切换，一般写入计算机程序中，处理器执行计算机程序，控制各个硬件部件执行相应动作。因此，本方案中，切换组件1044具体动作的时机也可以写入电器设备200的计算机程序中，与整机的状态保持吻合，实现自动切换。
比如：当电器设备200要运行第一驱动电机2运行对应的模式时，切换组件1044提前设定时间(如3秒钟、5秒钟等)发生动作，导通电连接部1046，使第二驱动电机3的绕组(32a、32b、32c)串联接入电源电路108，保证后续第一驱动电机2即可正常运行。
当电器设备200要切换至第二驱动电机3运行对应的模式时，切换组件1044提前设定时间(如3秒钟、5秒钟等)发生动作，断开电连接部1046，使第二驱动电机3的绕组(32a、32b、32c)与电源电路108断开，保证后续第二驱动电机3能够正常运行。

电源电路108包括交流电源接入电路1082和整流电路1096。交流电源接入电路1082的交流电源正极端1084接交流电源的正极，交流电源负极端1086接交流电源的负极，这样即可利用交流电源为电机控制器1供电，便于电器设备200利用常见的市政交流电等电源工作，提高电器设备200的普适性。而整 流电路1096能够将交流电转换为直流电，便于第一控制电路102根据第一驱动电机2的运行需求提供所需的电能，满足第一驱动电机2的运行需求。
其中，组件切换电路1042接在交流电源正极端1084与整流电路1096之间，以使第二驱动电机3的绕组(32a、32b、32c)串联在交流电源正极端1084与整流电路1096之间。
本方案能够直接将第二驱动电机3的绕组(32a、32b、32c)串入交流电源进线中，从而使得第二驱动电机3的绕组(32a、32b、32c)充当进线电抗器的功能。本方案结构简单，便于布线设计。
进一步地，切换组件1044包括至少一个切换件1050，切换件1050的种类包括开关元件和继电器中的至少一种。
切换组件1044主要通过开闭来实现电源电路108、电连接部1046、第二驱动电机3的绕组(32a、32b、32c)之间的通断。因此，常见的开关元件、继电器等均能满足该要求。
其中，切换件1050可以只有一种闭合状态，如单刀单掷开关，只控制一条线路的通断。切换件1050也可以具有多种闭合状态，如单刀双掷开关，通过选择具体的闭合状态，来实现多条线路的选择性通断。
当然，具有多种闭合状态的切换件1050也可以由多个只有一种闭合状态的切换件1050等效替换，如利用两个单刀单掷开关可以等效替换一个单刀双掷开关。
具体地，如图6所示，电连接部1046包括第一连接线路1071和第二连接线路1072。切换组件1044包括：第一切换件1051、第二切换件1052和第三切换件1053。

滚筒洗衣机300设有风道，风道内设有风机348，风机348用于驱动风道内的空气流动。风道的两端与滚筒314的前后两端分别连通，使得气流形成循环。风道内还可以设置冷凝器或者加热器，便于快速带走滚筒314内的湿空气，以从而实现烘干功能。风机电机344与风机348相连，用于驱动风机348旋转。具体地，风道包括依次连通的前风道336、主风道334和后风道350。主风道334位于外筒308下方；前风道336位于外筒308前方，通过外筒308前端部与外筒308内部空间连通；后风道350位于外筒308后方，通过外筒308后端部与外筒308内部空间连通。
