技术领域
本申请属于洗衣机制造技术领域，具体涉及一种外筒组件及洗衣机。
背景技术
随着人们生活质量的提高，对家用电器的节能、高效、低噪要求越来越高。目前滚筒洗衣机作为一种日常家用电器受到了广大用户的认可，但滚筒洗衣机工作过程中，电机的高速旋转会产生大量噪音。噪音是通过介质的振动传播的，真空降噪是工程实际中一种常用有效地主动降噪手段，利用这种手段，可以隔绝电机噪音的传播，从而实现对洗衣机电机运转的噪音消除目的。具体的，发明人所知道的洗衣机在电机处往往设置真空罩，将电机容纳于真空罩中，这种方式能够有效隔断电机运转时的噪音，但目前的真空罩内的真空环境在洗衣机出厂前一次性构造形成，随着洗衣机的运用时间的增加，真空罩及相关部位不可避免的发生老化形成泄露，从而使真空罩内的真空度降低甚至丧失真空度，真空环境隔断电机运转噪音的目的大打折扣甚至不能实现。
发明内容
因此，本申请要解决的技术问题在于提供一种外筒组件及洗衣机，能够保证电机安装腔内的真空度，从而保证电机安装腔对驱动电机运转噪音的隔断效果，提高用户的洗衣机的使用舒适性。
为了解决上述问题，本申请提供一种外筒组件，包括外筒，外筒的第一端面上构造有电机安装腔，电机安装腔内安装有驱动电机，还设有真空产生装置，真空产生装置的抽气管与电机安装腔贯通连接，当真空产生装置运转时，真空产生装置能够将电机安装腔抽真空至预设真空度。
在一些实施例中，第一端面上还构造有凹槽，凹槽与电机安装腔相互独立，真空产生装置安装于凹槽内。
在一些实施例中，电机安装腔具有处于外筒轴向上的开口，开口上盖设有 盖板。

在一些实施例中，外筒组件还包括双头端子，双头端子能够将驱动电机的电缆与外部电缆密封对接。
本申请还提供一种洗衣机，包括外筒组件，外筒组件为上述的外筒组件。
本申请提供的一种外筒组件、洗衣机，当电机安装腔被真空产生装置抽真空后，电机安装腔即保持为真空环境，这有效阻断了驱动电机在运转时产生的噪音，从而保证电机安装腔对驱动电机运转噪音的隔断效果，提高用户的洗衣机的使用舒适性，同时，由于电机安装腔与真空产生装置的抽气管贯通连接，从而在电机安装腔的真空度低于预设真空度能够及时地控制真空产生装置运转，再次将电机安装腔的真空度提高至预设真空度之上，这样一定程度上降低了对电机安装腔的密封要求，降低了相应部件的设计难度。

具体实施方式
结合参见图1至图3所示，根据本申请的实施例，提供一种外筒组件，包括外筒1，外筒1的第一端面上构造有电机安装腔11，电机安装腔11内安装有驱动电机2，还设有真空产生装置3，真空产生装置3的抽气管与电机安装腔11贯通连接，当真空产生装置3运转时，真空产生装置3能够将电机安装腔11抽真空至预设真空度，基于电机安装腔11的空间紧凑性方面的考虑，在一些实施例中，驱动电机2采用DD电机(Direct Driver，直驱电机)，当然，驱动电机2也可以采用BLDC(Brushless Direct Current Motor，无刷直流电机)电机。该技术方案中，当电机安装腔11被真空产生装置3抽真空后，电机安装腔11即保持为真空环境，这有效阻断了驱动电机2在运转时产生的噪音，从而保证电机安装腔11对驱动电机运转噪音的隔断效果，提高用户的洗衣机的使用舒适性，同时，由于电机安装腔11与真空产生装置3的抽气管贯通连接，从而在电机安装腔11的真空度低于预设真空度能够及时地控制真空产生装置3运转，再次将电机安装腔11的真空度提高至预设真空度之上，这样一定程度上降低了对电机安装腔11的密封要求，降低了相应部件的设计难度。
前述的真空产生装置3例如可以采用常见的微型真空泵即可，为了保证电机安装腔11内的真空度，在一些实施例中，微型真空泵的选型应选择极限真空度达到2～10Pa的真空泵，在一些实施例中，其能够保证电机安装腔11内的预设真空度为10Pa。
在一些实施例中，第一端面上还构造有凹槽12，凹槽12与电机安装腔11相互独立，真空产生装置3安装于凹槽12内，也即使真空产生装置3的安装能够沉入凹槽12内。
电机安装腔11的构造形式可以是多样的，基于外筒组件在其轴向长度上的尺寸紧凑化的考虑，在一些实施例中，前述的驱动电机2采用DD电机。更进一步的，电机安装腔11具有处于外筒1轴向上的开口，开口上盖设有盖板13，也即在安装驱动电机2时，其安装空间处于外筒组件的轴向上，通过开口即可轻松实现驱动电机2的安装。
具体的，盖板13包括板体131，板体131上还具有沿板体131的厚度方向延伸的凸台132，开口的唇口处构造有环槽，板体131的边缘部位与环槽抵接，凸台132容纳于电机安装腔11内，盖板13与开口之间形成弯折密封效果。更进一步的，外筒组件还包括密封件4，密封件4具有包裹于凸台132的第一密 封部41以及夹设于板体131与环槽之间的第二密封部42，密封件4在凸台132的轴向及径向方向上对开口也即电机安装腔11进行有效密封，有利于电机安装腔11内的真空环境的保持。可以理解的，密封件4的耐介质压力不应低于0.1Mpa。在一些实施例中，板体131上还设置有加强筋，以增强盖板13的结构强度，例如，加强筋处于板体131背离凸台132一侧的端面上。
前述方案能够对驱动电机2的运转噪音实现有效阻断，但同时会给驱动电机2的散热带来不利影响，为了及时对驱动电机2进行冷却散热，在一些实施例中，外筒组件还包括冷却部件，冷却部件能够冷却电机安装腔11及驱动电机2。
具体的，冷却部件包括冷却管51，冷却管51为空心管路，冷却管51的进口一端与水泵52贯通连接，冷却管51的出口一端处于电机安装腔11之外，此时的水泵52的进水口例如可以与自来水龙头连接即可；进一步地，冷却管51与外筒1通过注塑的方式形成为一体。
进一步地，冷却管51至少部分地处于电机安装腔11内，这能够增大冷却管51与电机安装腔11的接触面积，进而能够提高冷却管的散热效率，而作为一种更环保性的方式，在一些实施例中，水泵52的进水口与外筒1的容水腔相连通，也即，水泵52能够将容水腔中的洗涤用水作为冷却管51中的冷却用水，这种方式一方面能够充分利用容水腔中的洗涤水，更为重要的是，冷却管51的出口一端也与外筒1的容水腔相连通，从而与容水腔中的洗涤水形成循环，这能够对洗涤水进行升温加热，提高对衣物的洗涤效果。
电机安装腔11的腔壁上设有导热层6，导热层6例如可以采用环氧树脂形成。在一些实施例中，导热层6能够与驱动电机2的安装螺栓等连接件(例如驱动电机2的转子采用的6个螺栓及3个定位销与外筒1固定连接)接触，从而能够将驱动电机2的热量传递到导热层6上，进一步地，导热层6包裹于冷却管51处于电机安装腔11内的部分上，导热层6与冷却管51内的水实现热交换。在一些实施例中，导热层6的厚度为1mm-3mm。
在一些实施例中，外筒组件还包括双头端子，双头端子能够将驱动电机2的电缆与外部电缆密封对接，从而保证对驱动电机2供电的同时，不对电机安装腔11的密封性造成不利影响。在一些实施例中，双头端子与外筒1注塑一体成型，从而保证双头端子与外筒1之间可能的泄露问题。
根据本申请的实施例，还提供一种洗衣机，包括上述的外筒组件，可以理解的，外筒组件的外筒1的容水腔内还设有内筒，内筒的轴向末端将与驱动电 机2的转子连接，从而保证驱动电机2对内筒旋转的驱动，进一步的，外筒1的电机安装腔11处构造有与内筒相连通的轴孔，而轴孔中将设置密封轴承油封7实现对电机安装腔11的密封，如前述密封件4的耐介质压力的要求，密封轴承油封7的耐介质压力也不应低于0.1Mpa。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各有利方式可以自由地组合、叠加。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。以上仅是本申请的一些实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本申请的保护范围。
