在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
本实施例提供一种带有容积可变容器的处理剂投放装置，如图1至图5所示，包括处理剂盒1、分配器盒2、容积可变容器3、连接模块4、负压传感器5及抽取装置6，分配器盒2设置在处理剂盒1内且分配器盒2上设有放置槽20，容积可变容器3可拆卸放置在放置槽20内且容积可变容器3内限定出盛放处理剂的处理剂腔室，处理剂腔室与外界环境隔绝且体积随处理剂的减少而同步缩小，连接模块4位于抽取装置6和容积可变容器3之间，连接模块4内限定出与外界环境隔绝的流道401，且流道401分别与处理剂腔室、抽取装置6的进口及负压传感器5密封连接，负压传感器5设置为检测流道401的压力并在压力小于预设压力时发出报警信号。
本实施例的流道401分别与处理剂腔室、抽取装置6的进口及负压传感器5密封连接，即连接模块4分别与容积可变容器3、抽取装置6的进口及负压传感器5密封连接。为了保证处理剂腔室的体积随处理剂的减少而同步缩小，要求流道401内的压力低于外界环境压力，即流道401内为负压。由于流道401与外界环境隔绝，使得外界环境中的空气不会进入流道401内，当抽取装置6抽取容积可变容器3内的处理剂时，流道401内的压力基本维持不变；当容积可变容器3内的处理剂被抽完时，此时抽取装置6抽取的是流道401内的处理剂和空气中的至少一种，使得流道401内的压力急剧下降，此时负压传感器5检测到的压力骤减，当负压传感器5检测的压力小于预设压力时，负压传感器5发出报警信号，从而提醒使用者及时更换容积可变容器3。
如图4所示，本实施例的流道401的个数为两个，两个流道401隔绝设置，每个流道401与一个容积可变容器3连通。在其他实施例中，流道401的个数并不限于本实施例的两个，还可以为一个、三个或者多于三个，具体根据实际需要设置。
本实施例的抽取装置6为双出口泵，如图2至图4所示，连接模块4上设有两 个第一通孔402，每个第一通孔402分别与双出口泵的一个出口对应设置，盒本体11上设有两个第二通孔110，每个第二通孔110分别与一个第一通孔402连通，使得双出口泵的两个出口分别通过相应的第二通孔110与盒本体11连通，当该双出口泵正转时，能够将一个流道401内的处理剂抽至盒本体11内；当该双出口泵反转时，能够将另一个流道401内的处理剂抽至盒本体11内。在其他实施例中，抽取装置6还可以为其他抽吸功能的设备，具体根据用户的实际需求选定。
如图1和图2所示，本实施例的连接模块4、负压传感器5及抽取装置6设置在处理剂盒1的外侧。在其他实施例中，还可以将连接模块4、负压传感器5及抽取装置6设置在处理剂盒1的内侧，具体根据实际需要进行设置。
本实施例提供的带有容积可变容器的处理剂投放装置，由于处理剂盛放在与外界环境隔绝的处理剂腔室内，处理剂腔室内不易滋生细菌，即使洗衣机长时间不使用，处理剂腔室中的处理剂也不会干涸导致管路堵塞，连接模块4不但起到密封抽取装置6的进口和处理剂腔室的出口作用，还使密封抽取装置6的进口和处理剂腔室的出口连通，与相关技术相比，缩短了抽取装置6的吸液行程，使得处理剂投放装置的体积更小，减小了处理剂投放装置的占用空间，当容积可变容器3内的处理剂被用完时，由于流道401与外界环境隔绝，使得流道401内的压力急剧降低，当负压传感器5检测到的压力小于预设压力时发出报警信号，从而提醒使用者及时更换容积可变容器3。
如图1所示，本实施例的处理剂盒1包括盒本体11和盒盖12，如图1和图5所示，盒盖12上设有进水孔1201和与进水孔1201连通的多个喷孔1202，本实施例的多个喷孔1202相当于相关技术中的花洒结构，经进水孔1201流入盒盖12内的水能够从喷孔1202喷出并将抽取装置6抽出的处理剂冲入盒本体11内，进而流入洗衣机的洗衣桶内。在其他实施例中，若是用于洗碗机或者其他洗涤物品的机器中，盒本体11内带有处理剂的水能够流至相应的洗涤筒内，进而实现对相应物品的洗涤。
如图3和图4所示，本实施例的连接模块4的顶端设有与流道401连通的连接管411，负压传感器5的检测口与连接管411密封连接。如图4所示，本实施例的流道401包括与容积可变容器3连通的处理剂流道4011和与连接管411连通的安全流道4012，安全流道4012的底端设有与处理剂流道4011连通的开口40121，安全流道4012的顶端高于处理剂流道4011且低于连接管411，即使处理剂流道4011内的处理剂通过开口40121进入安全通道，处理剂也不会直接流入与负压传感器 5连接的连接管411，降低了因处理剂进入连接管411并与负压传感器5接触导致负压传感器5发生损坏的可能性，提升了负压传感器5的安全性。
如图4所示，本实施例的安全流道4012的底面为斜面，开口40121位于斜面的底端。即使处理剂进入安全通道，一旦处理剂通道内的液面下降，安全通道内的处理剂能够沿斜面的底端流回处理剂通道，使得安全流道4012内的处理剂被彻底排入处理剂通道，降低了安全通道内残留处理剂的可能性。
本实施例的连接管411的容量为第一体积，连接模块4包括与容积可变容器3连接的接头421，接头421与流道401连通，接头421内插入部分容积可变容器3前后的容量变化量为第二体积，第二体积小于第一体积。在一实施例中，接头421内未插入容积可变容器3时，接头421内部的容量为第三体积，与容积可变容器3连接后的容量为第四体积，由于部分容积可变容器3插入接头421内，使得接头421的容量缩小，即第四体积小于第三体积，且第三体积与第四体积的差值为第二体积。
在一实施例中，当接头421未与容积可变容器3连接时，接头421和流道401内有处理剂，且此时接头421的容量较大，接头421内装有较多的处理剂，将容积可变容器3与接头421连接时，容积可变容器3的部分结构插入接头421内，使得接头421的容量缩小，这一变化量为第二体积，使得第二体积的处理剂被容积可变容器3压入流道401内，进而连接管411内的空气被压缩，限定第二体积小于第一体积能够防止流道401和接头421内的处理剂通过连接管411与负压传感器5接触，降低了处理剂与负压传感器5接触而损坏负压传感器5的可能性，延长了负压传感器5的使用寿命，增加了该带有容积可变容器的处理剂投放装置的使用年限。
如图3所示，本实施例的连接模块4包括密封连接的第一连接件41和第二连接件42，第一连接件41上形成有连接管411，即连接管411与第一连接件41一体成型设置。本实施例的第一连接件41和第二连接件42为塑料件且第一连接件41和第二连接件42通过焊接密封连接。在其他实施例中，第一连接件41和第二连接件42还可以通过塑料膜36并采用固定连接的方式实现第一连接件41和第二连接件42的密封连接，或者，采用3D打印技术直接打印出连接模块4，具体加工方式根据实际需求选定。
如图2和图7所示，本实施例的容积可变容器3包括筒体31和可滑动设置在筒体31内的活塞34，活塞34将筒体31的腔室分割为隔绝的第一连通腔室311和处理 剂腔室37，筒体31的第一端设有与处理剂腔室37连通的处理剂出口，筒体31的第二端设有连通第一连通腔室311和外界环境的第一连通口310，如图2所示，抽取装置6抽取处理剂腔室37内的处理剂时，随着处理剂的减少，处理剂腔室37内的处理剂对活塞34的压力小于第一连通腔室311内的空气对活塞34的压力，即活塞34的两侧存在压力差，此时活塞34在第一连通腔室311内的空气的作用下朝向处理剂出口的方向移动，使得处理剂腔室37的体积随处理剂的减少而减小。为了更好的观察处理剂腔室37内的处理剂的容量，筒体31为透明筒，透明筒上标注有刻度。
在其他实施例中，如图6所示，该容积可变容器3包括安装固定结构32和设置在安装固定结构32内的袋装处理剂33，安装固定结构32可拆卸安装在放置槽20内且设置为支撑袋装处理剂33，袋装处理剂33的外接口330与流道401连通，安装固定结构32设置为将袋装处理剂33的袋体限定在分配器盒2的放置槽20内。其中，安装固定结构32包括第一安装体321和第二安装体322，第一安装体321上设有第一定位部3211，第二安装体322能够连接于第一安装体321上，第二安装体322上设有第二定位部3221，第一安装体321和第二安装体322中的至少一个上设有容置腔，第二安装体322连接于第一安装体321上时，第一定位部3211和第二定位部3221能够夹持定位袋装处理剂33的外接口330，以使外接口330与流道401连通。安装固定结构32能够安装袋装处理剂33，实现了对袋装处理剂33的支撑，避免了袋装处理剂33的袋体太软不便在分配器盒2中固定的问题，使袋装处理剂33能够通过该安装固定结构32固定于配器盒2中并与流道401连通，使用方便，用户体验感较好，需要说明的是，该容积可变容器3的第一安装体321和第二安装体322为可拆卸连接，安装固定结构32可循环使用。在其他实施例中，该第一安装体321和第二安装体322还可以为一体成型结构，即安装固定结构32为一体成型件，袋装处理剂33设置在安装固定结构32内，更换时，将安装固定结构32和袋装处理剂33整体更换。
在其他实施例中，如图8所示，还可以是容积可变容器3包括容纳筒35，容纳筒35的形状为固定形状，容纳筒35的容纳腔室的体积固定不变，容纳筒35内设有沿自身长度方向延伸且形状可变的塑料膜36，处理剂出口的四周与容纳筒35的内壁密封连接，该塑料膜36将容纳筒35的容纳腔室分为隔绝的处理剂腔室37和第二连通腔室351，处理剂腔室37的出口与流道401连通，容纳筒35上设有连通第二连通腔室351和外界环境的第二连通口350，当处理剂腔室37内装满处 理剂时，处理剂腔室37的体积最大，第二连通腔室351的体积最小，随着处理剂的减少，处理剂腔室37的体积逐渐减小，塑料膜36随处理剂腔室37的体积的减小而移动，空气逐渐通过第二连通口350进入第二连通腔室351内，使得第二连通腔室351的体积逐渐增大，且处理剂腔室37的体积与第二连通腔室351的体积的和为容纳筒35的总体积。为了便于查看容纳筒35内处理剂的多少，该容纳筒35可以设置为透明的塑料筒，塑料膜36可以设置为带颜色的塑料膜36。在其他实施例中，容纳筒35也可以为非透明的塑料筒，塑料膜36也可以为透明膜，具体根据用户的实际需求设置。
本实施例中的处理剂应当进行广义的理解，既可以为洗衣液、柔顺剂等日常生活中用于衣物清洗的处理剂，还可以为消毒剂、漂白剂等对衣物具有处理作用的处理剂，具体根据用户的实际需求选定。
本实施例还提供一种洗衣机，包括本方案所述的带有容积可变容器的处理剂投放装置。
本实施例提供的洗衣机具有处理剂不易滋生细菌、处理剂管路不会堵塞、体积较小和能够提醒使用者及时更换容积可变容器3的特点。
