具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图2描述根据本申请实施例的用于投放洗剂的投放组件。
如图1和图2所示，根据本申请第一方面实施例的用于投放洗剂的投放组件，包括：主管壳1。主管壳1具有进液端和出液端，水适于通过进液端流入主管壳1内并从出液端流出，主管壳1的侧壁上形成有进气口102和一个吸入口101，进气口102和吸入口101可以间隔开设置，吸入口101和进气口102均位于进液端和出液端之间，洗剂适于通过吸入口101流入主管壳1内，气体适于通过进气口102流入主管壳1内，由进气口102进入的气体可以为空气。
可以利用主管壳1内水流的流动产生的负压作为推动力，使得洗剂通过吸入口101被吸入至主管壳1内，例如主管壳1可以为文丘里管。也可以利用泵等作为动力，通过泵的抽吸作用使得洗剂通过吸入口101被吸入至主管壳1内。或者，在主管壳1为文丘里管时，同时利用主管壳1内水流的流动产生的负压以及泵的抽吸作用，使得洗剂通过吸入口101被吸入至主管壳1内。
可以利用主管壳1内水流的流动产生的负压作为推动力，使得气体通过进气口102被吸入至主管壳1内，例如主管壳1可以为文丘里管。也可以利用泵、风机等作为动力，通过泵或风机的抽吸作用使得气体通过进气口102被吸入至主管壳1内。或者，在主管壳1为文丘里管时，同时利用主管壳1内水流的流动产生的负压以及泵或风机的抽吸作用，使得气体通过进气口102被吸入至主管壳1内。
由此，在该投放组件用于洗衣机的投放装置时，投放装置可以将洗剂投至洗衣机的洗涤桶内。在利用该投放组件投放洗剂的过程中，水通过主管壳1的进液端进入主管壳1内，由吸入口101吸入的洗剂以及由进气口102吸入的气体也进入主管壳1内，气体、水和洗剂在主管壳1内混合，使得洗剂充分溶解，充分混合溶解后通过出液端流入洗衣机的洗涤桶内。由此，在洗剂进入主管壳1内之后，洗剂溶解在主管壳1内的水流中，同时由于有气体进入主管壳1内，通过气体、水和洗剂三者之间的充分混合，可以促进洗剂的溶解，例如在洗剂为洗涤剂时，可以提高洗剂的发泡效果，发泡后的泡沫更为细腻，提高洗净效果。
在利用上述投放组件投放洗剂的过程中，可以先供洗剂再供气体，也可以先供气体再供洗剂，或者还可以是洗剂和气体交替提供。主管壳1内的水流可以在气体和洗剂的投放之前、投放之后或者投放之时打开，主管壳1内的水流也可以和气体及洗剂的投放交替进行。其中，主管壳1内的水流在气体和洗剂的投放之前打开，这样洗剂和气体可以从一开始就接触水流，而使得洗剂不在管道内过多积累，使得洗剂溶解充分、均匀，减少残留结块风险，从而降低管路堵塞风险。
所述洗剂包括洗涤剂、柔顺剂、消毒剂等，即洗剂泛指用于洗衣过程中投放的添加剂。当洗衣机处在洗涤阶段，洗涤剂可以通过吸入口101进入主管壳1内，气体可以通过进气口102进入主管壳1内，可以使得洗涤剂充分溶解，提高洗涤剂的发泡效果，提高洗净效果；当洗衣机处在漂洗阶段，柔顺剂、消毒液可以通过吸入口101进入主管壳1内，气体可以通过进气口102进入主管壳1内，可以使得柔顺剂、消毒液充分溶解，改善手感、提高消毒杀菌率。在洗衣机的洗涤阶段和漂洗阶段，投放相应的洗剂结束之后，可以通过吸入口101吸入水流冲洗吸入口101。由于该投放组件可以将洗剂充分溶解在水中，在洗涤过程中使得洗剂能发挥出更充分的作用，例如可以提高洗净效果、改善手感、提高消毒杀 菌率。
可选地，进气口102和吸入口101邻近设置，通过将进气口102和吸入口101邻近设置，可以使得洗剂和气体进入主管壳1之后在很短时间内即可接触并充分混合，从而可以进一步地提高洗剂的溶解效果和发泡效果。
另外，由于气体是通过进气口102进入主管壳1内，洗剂是通过吸入口101进入主管壳1内，而进气口102和吸入口101是相互独立的，洗剂和气体分别由各自独立的通道进入主管壳1内，使得洗剂和气体的通入互不影响，使得在没有冲洗的情况下，不会因洗剂在空气影响下结块凝结而影响气体的通入，降低气路的堵塞风险。
根据本申请实施例的用于投放洗剂的投放组件，通过设置进气口102，在洗剂通过吸入口101流入主管壳1内的过程中，通过进气口102向主管壳1内通入气体，通过气体的扰动作用，可以使得洗剂在水流中充分溶解，可以提高洗剂的发泡效果，提高洗净效果，也可以减少残留洗剂的结块风险，从而可以降低管路的堵塞风险。并且，洗剂和气体分别由各自独立的通道进入主管壳1内，使得洗剂和气体的通入互不影响，使得在没有冲洗的情况下，不会因洗剂在空气影响下结块凝结而影响气体的通入，降低气路的堵塞风险。
根据本申请的一些实施例，参照图1和图2，主管壳1为文丘里管，主管壳1包括依次连接的第一管段11、第二管段12和第三管段13，第二管段12的流通面积小于第一管段11的流通面积且小于第三管段13的流通面积，进液端位于第一管段11，出液端位于第三管段13，吸入口101形成在第一管段11或第二管段12，进气口102形成在第一管段11或第二管段12。通过将主管壳1设置为文丘里管，水流通过进液端进入第一管段11，而后依次流经第二管段12和第三管段13，由于第二管段12的流通面积较小，在水流经第二管段12过程中，可以产生较大负压。
在吸入口101形成在第一管段11或第二管段12时，可以利用上述的负压作用，使得洗剂通过吸入口101吸入主管壳1内。在进气口102形成在第一管段11或第二管段12时，可以利用上述的负压作用，使得气体通过进气口102吸入主管壳1内。其中，洗剂和气体均可以仅通过上述负压作用进入主管壳1内；或者，气体通过上述负压作用进入主管壳1内，洗剂主要利用泵的抽吸作用进入主管壳1内。
并且，在洗剂、气体和水流在第二管段12内混合的过程中，由于第二管段12的流动面积较小，水流速度增大，湍动效果好，因此混合效果好，可以进一步地提高洗剂的溶解效果和发泡效果，提高洗净效果。
根据本申请的一些可选实施例，参照图1，吸入口101和进气口102均形成在第一管段11。由此，洗剂通过吸入口101进入第一管段11且气体通过进气口102进入第一管段11，气体和洗剂在第一管段11内可以与水流初步混合，而后洗剂和气体随着水流流动至第二管 段12，从而使得气体和洗剂流入第二管段12之前，可以先在第一管段11内与水流进行预混，在洗剂和气体随着水流流动至第二管段12内时，由于第二管段12的流通面积减小，水流速度增大，湍动效果好，因此混合效果增强，从而产生更多细腻泡沫，雷诺数计算值可达10000以上，从而可以更好地提高洗剂的溶解效果和发泡效果，更好地提高洗净效果，可以在相同洗净和去污要求下节省10％以上洗剂。
根据本申请的一些可选实施例，参照图2，吸入口101形成在第一管段11，洗剂由吸入口101吸入第一管段11，而后随着水流流入第二管段12，在洗剂流入第二管段12之前，洗剂可以与水流预混。进气口102形成在第二管段12，气体由进气口102进入第二管段12，随着水流流入第二管段12的洗剂与第二管段12内的气体混合，同时由于第二管段12的流通面积减小，水流速度增大，湍动效果好，因此混合效果增强，从而产生更多细腻泡沫，从而可以更好地提高洗剂的溶解效果和发泡效果，更好地提高洗净效果。
根据本申请的一些实施例，参照图1和图2，主管壳1内设有内管3，内管3具有进口和出口30，进口邻近进液端，水适于通过进口流入内管3内并从出口30流出至主管壳1内。其中，水可以直接通过进口流入内管3内，水也可以先流入进液端，然后由内管3的进口流入内管3内。由此，通过在主管壳1内设有内管3，且使得水流流入内管3，由于内管3的横截面积可以小于主管壳1的横截面积，从而可以增加水流的流速，水流流经内管3后流速可以增大，水流从内管3的出口30可以以较高的流速喷出，增强水流的冲击效果，使得水、洗剂和气体三者充分混合、发泡，进而可以进一步地提高洗剂的溶解效果和发泡效果，提高洗净效果。
根据本申请的一些可选实施例，参照图1和图2，内管3的外侧壁与主管壳1的内侧壁之间限定出流动空间301，吸入口101形成在流动空间301的外侧壁上，进气口102形成在流动空间301的外侧壁上或进气口102位于流动空间301的下游(所述“进气口102位于流动空间301的下游”是指进气口102位于整个流动空间301外的下游，所述下游是相对于水流的流动方向而言)。由此，在吸入口101和进气口102均形成在流动空间301的外侧壁上时，洗剂通过吸入口101、气体通过进气口102可以先进入上述流动空间301内，使得洗剂和气体在接触水流之前充分混合，使得洗剂和气体在上述流动空间301内充分混合后再接触水流，从而可以进一步地提高洗剂的溶解效果和发泡效率，进一步地提高洗净效果；在吸入口101形成在流动空间301的外侧壁上且进气口102位于流动空间301的下游时，洗剂由吸入口101进入流动空间301并流向主管壳1的位于流动空间301的下游部分，与水流以及由进气口102进入的气体混合，使得水、洗剂和气体三者混合、发泡，进而可以提高洗剂的溶解效果和发泡效果，提高洗净效果。
可选地，流动空间301的横截面为围绕内管3延伸的环形。由此，使得流动空间301 较大，从而使得洗剂和气体在流动空间301内可以充分混合。
在本申请的一些可选实施例中，参照图1和图2，内管3包括相连的主体段31和压缩段32，压缩段32可以为内径均匀的管段，进口形成在主体段31，出口30形成在压缩段32，压缩段32的流通面积小于主体段31的流通面积。由此，在水流流经内管3的过程中，水流通过压缩段32的过程中，水流可以进一步地得到加速，从而使得水流可以以较高的速度从出口30喷出，进一步地增大水流的冲击力，进一步地使得水、洗剂和气体充分混合、发泡，进而可以进一步地提高洗剂的溶解效果和发泡效果，提高洗净效果。
可选地，参照图1，吸入口101和进气口102均位于压缩段32的上游(所述“吸入口101和进气口102均位于压缩段32的上游”是指吸入口101和进气口102均位于整个压缩段32外的上游，所述上游是相对于水流的流动方向而言)。由此，使得吸入口101及进气口102与内管3的出口30之间具有一定的距离，在洗剂和气体分别通过吸入口101和进气口102进入流动空间301之后，在洗剂和气体接触水流之前，使得洗剂和气体可以有充分的空间和时间混合。
在本申请的一些可选实施例中，参照图1，内管3包括连接段33，连接段33连接主体段31和压缩段32，在由主体段31至压缩段32的方向上，连接段33的外侧壁朝向邻近主管壳1的中心轴线方向倾斜延伸，连接段33的最小流通面积不小于压缩段32的流通面积，吸入口101和进气口102均位于连接段33的上游(所述“吸入口101和进气口102均位于连接段33的上游”是指吸入口101和进气口102均位于整个连接段33外的上游，所述上游是相对于水流的流动方向而言)。由此，通过设置的连接段33，可以使得主体段31和压缩段32之间的流通面积变化缓和，减少流动损失。并且，由于吸入口101和进气口102均位于连接段33的上游，可以进一步地增加吸入口101及进气口102与内管3的出口30之间的距离，在洗剂和气体接触水流之前，使得洗剂和气体可以有更为充分的空间和时间混合。另外，在由吸入口101吸入的洗剂和由进气口102吸入的气体进入流动空间301内后，通过连接段33的外侧壁的导向作用，可以使得洗剂和气体更为顺畅向前流动与水流接触。
根据本申请的一些可选实施例，参照图1和图2，主管壳1为文丘里管，主管壳1包括依次连接的第一管段11、第二管段12和第三管段13，第二管段12的流通面积小于第一管段11的流通面积且小于第三管段13的流通面积，进液端位于第一管段11，出液端位于第三管段13，内管3设在第一管段11内，内管3的外侧壁与第一管段11的内侧壁之间限定出流动空间301，出口30邻近第二管段12，进气口102形成在流动空间301的外侧壁上或进气口102形成在第二管段12。通过将主管壳1设置为文丘里管，水流通过进液端进入第一管段11，而后依次流经第二管段12和第三管段13，由于第二管段12的流通面积减小，在水流经第二管段12过程中，可以产生较大负压，可以利用上述的负压作用，使得洗剂和 气体在负压的作用下分别通过吸入口101和进气口102吸入主管壳1内。其中，洗剂和气体均可以仅通过上述负压作用进入主管壳1内；或者，气体通过上述负压作用进入主管壳1内，洗剂主要利用泵的抽吸作用进入主管壳1内。
其中，参照图2，在进气口102形成在第二管段12时，由于第二管段12的流通面积减小，产生的负压作用力更大，可以使得进气口102进入的气体量更多、气流速度更快，从而可以进一步地提高洗剂的溶解及发泡效果。
并且，在洗剂、气体和水流在第二管段12内混合的过程中，由于第二管段12的流动面积较小，水流速度增大，湍动效果好，因此混合效果好，可以进一步地提高洗剂的溶解效果和发泡效果，提高洗净效果。
进一步地，通过在第一管段11内设置内管3，由于内管3的横截面积可以小于主管壳1的横截面积，从而可以增加水流的流速，水流流经内管3后流速可以增大，水流从内管3的出口30可以以较高的流速喷出至第二管段12内，增强水流的冲击效果。并且，参照图1，在进气口102和吸入口101均形成在流动空间301的外侧壁上时，洗剂和气体流入流动空间301充分混合之后再流入第二管段12接触水流，使得水、洗剂和气体在主管壳1内充分混合、发泡，进而可以进一步地提高洗剂的溶解效果和发泡效果，提高洗净效果。
根据本申请的一些实施例，进气口102处设有用于打开和关闭进气口102的控制阀。由此，方便控制气体进入主管壳1内。例如，在控制阀打开时，气体可以从进气口102进入，并从吸入口101流入主管壳1内；在控制阀关闭时，停止向主管壳1内供气体。
根据本申请的一些可选实施例，主管壳1为文丘里管，主管壳1包括依次连接的第一管段11、第二管段12和第三管段13，第二管段12的流通面积小于第一管段11的流通面积且小于第三管段13的流通面积，进液端位于第一管段11，出液端位于第三管段13，吸入口101形成在第一管段11或第二管段12，进气口102形成在第一管段11或第二管段12，控制阀为单向阀，单向阀在由进气口102至主管壳1的内腔的方向上单向导通。由此，通过将主管壳1设置为文丘里管，且将进气口102形成在第一管段11或第二管段12，在水流流经主管壳1的过程中，可以利用水流产生的负压作用，此时单向阀在压差的作用下打开，从而使得气体例如空气从进气口102进入；在主管壳1内停止供水流时，单向阀关闭。由此，使得控制阀的控制方便且可靠。
参照图1和图2，根据本申请第二方面实施例的用于投放洗剂的投放装置，包括：投放组件和洗剂存放盒4，投放组件为根据本申请上述第一方面实施例的投放组件。
洗剂存放盒4设在主管壳1的外侧且洗剂存放盒4与主管壳1相连，洗剂存放盒4的内腔与吸入口101连通，洗剂存放盒4内的洗剂适于通过吸入口101流入主管壳1内。
其中，洗剂存放盒4内可以存放洗涤剂，洗剂存放盒4内也可以同时存放洗涤剂、柔顺剂、消毒剂等多种类型洗剂。当洗衣机处在洗涤阶段，洗剂存放盒4内的洗涤剂可以通过吸入口101进入主管壳1内；当洗衣机处在漂洗阶段，洗剂存放盒4内的柔顺剂、消毒液可以通过吸入口101进入主管壳1内。在洗衣机的洗涤阶段和漂洗阶段，投放相应的洗剂结束之后，可以通过吸入口101吸入水流冲洗吸入口101。
根据本申请实施例的用于投放洗剂的投放装置，通过设置上述的投放组件，可以使得洗剂在水流中充分溶解，可以提高洗剂的发泡效果，提高洗净效果，也可以减少残留洗剂的结块风险，从而可以降低管路的堵塞风险。并且，洗剂和气体分别由各自独立的通道进入主管壳1内，使得在没有冲洗的情况下，不会因洗剂在空气影响下结块凝结而影响气体的通入，降低气路的堵塞风险。
根据本申请第三方面实施例的洗衣机，包括：洗涤桶和投放装置，投放装置为根据本申请上述第二方面实施例的投放装置。投放装置适于向洗涤桶投放洗剂，出液端与洗涤桶连通。在洗衣机工作的过程中，需要向洗衣机的洗涤桶内投放洗剂时，水流可以通过进液端进入主管壳1内，洗剂通过吸入口101进入主管壳1内，气体通过进气口102进入主管壳1内，洗剂、气体和水流在主管壳1内充分混合，混合后从出液端流出至洗涤桶内。
根据本申请实施例的洗衣机，通过设置上述的投放装置，可以使得洗剂在水流中充分溶解，可以提高洗剂的发泡效果，提高洗净效果，也可以减少残留洗剂的结块风险，从而可以降低管路的堵塞风险，并且洗剂和气体分别由各自独立的通道进入主管壳1内，降低气路的堵塞风险。
根据本申请第四方面实施例的洗衣机的洗剂投放方法，洗衣机包括向洗衣机的洗涤桶投放洗剂的投放装置，投放装置包括投放组件和洗剂存放盒4，投放组件包括主管壳1，主管壳1具有进液端和出液端，出液端与洗涤桶连通，水适于通过进液端流入主管壳1内并从出液端流出，主管壳1的侧壁上形成有进气口102和一个吸入口101，进气口102和吸入口101可以间隔开设置，吸入口101和进气口102均位于进液端和出液端之间，气体适于通过进气口102流入主管壳1内，洗剂存放盒4设在主管壳1的外侧且洗剂存放盒4与主管壳1相连，洗剂存放盒4的内腔与吸入口101连通，洗剂存放盒4内的洗剂适于通过吸入口101流入主管壳1内，洗剂投放方法包括如下步骤：
先控制水通过进液端流入主管壳1内；
再控制洗剂从吸入口101、气体从进气口102分别流入主管壳1内。
由此，使得主管壳1内的水流在气体和洗剂的投放之前打开，这样洗剂和气体可以从 一开始就接触水流，而使得洗剂不在管道内过多积累，使得洗剂溶解充分、均匀，减少残留结块风险，从而降低管路堵塞风险。
其中，在控制洗剂和气体流入主管壳1内的过程中，可以先供洗剂再供气体，也可以先供气体再供洗剂，或者还可以是洗剂和气体交替提供。
另外，对于该实施例中的剂投放方法所使用的投放装置，具体结构和说明均可参照上述，这里不再赘述。并且，上述第二方面实施例的投放装置均可以用于该实施例中的洗衣机，并采用该洗剂投放方法进行投放洗剂。
根据本申请实施例的洗衣机的洗剂投放方法，在洗剂通过吸入口101流入主管壳1内的过程中，通过进气口102向主管壳1内通入气体，可以使得洗剂在水流中充分溶解，可以提高洗剂的发泡效果，提高洗净效果，也可以减少残留洗剂的结块风险，从而可以降低管路的堵塞风险。并且，通过控制使得洗剂和气体在水流进入主管壳1之后再进入主管壳1内，这样洗剂和气体可从一开始就接触水流，而使得洗剂不在管道内过多积累，从而可以进一步地提升洗剂溶解效果，进一步地减少洗剂残留结块风险和管路堵塞风险。
