一种洗衣机注水盒结构及洗衣机 技术领域
本发明属于衣物处理设备的技术领域，具体涉及一种洗衣机进水用的注水盒结构，还涉及一种装有上述注水盒结构的洗衣机。
背景技术
随着消费者对生活品质的提高，洗衣机已经离不开人们的生活。注水盒作为洗衣机上重要一个部件，一般都是塑料件，在注水盒内安装有可抽拉的投放盒，投放盒内盛放有待投放的洗衣粉、洗衣液、消毒液、柔顺剂等等添加物，以使得流经注水盒的进水水流可将上述添加物一并冲入洗衣机桶内，进而实现对洗衣机内桶中盛放的待处理负载进行洗涤、浸湿等处理。
现有的注水盒结构普遍是在注水盒的顶部分隔出一区域，该区域构成独立的注水腔，将洗衣机进水水流先引入注水腔、经注水腔缓冲分流后，再经注水腔的注水口流入投放盒中。
但是，由于洗衣机供水水源的水压可能过大、或不平稳，有可能会使流入注水腔中的水流过急，进而就会造成注水腔内压力过大、流向投放盒的注水水流的流速会产生波动，甚至会造成注水盒溢水外泄的问题。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种洗衣机注水盒结构，对注水盒的过急进水水流进行分流，以避免注水盒产生溢水；同时， 本发明还提供了一种洗衣机注水盒结构，以实现对注水盒内气压进行调节、稳定注水流速的目的。
为解决上述技术问题，本发明采用技术方案的基本构思是：
一种洗衣机注水盒结构，其包括：内部中空的注水盒，可向外抽拉的安装于注水盒中的投放盒，注水盒的顶部设有注水腔，注水腔的底部设有向投放盒内注入进水的注水口，注水腔内还设有与注水盒中空腔室直接连通的溢水口。
进一步，注水口和溢水口分别设于注水腔沿投放盒抽拉方向的相对两端；优选的，注水口设于注水腔的第一端，第一端为注水腔朝向投放盒拉出方向一端；溢水口设于注水腔的第二端，第二端为注水腔朝向投放盒推入方向的一端。

进一步，溢水口与投放盒在水平面中的投影相交错排布；优选的，投放盒的推入端与注水盒的内壁之间具有间距，注水腔的溢水口设于所述间距空间的上方，溢水口流出的溢水水流直接经间距空间注入投放盒下方的注水盒腔室中。
进一步，投放盒内具有顶部敞口的、供添加剂投放的投放腔，注水腔的注水口设于投放腔的顶部敞口的相对上方；投放腔内设有将投放腔内部与投放盒下方的注水盒底部空间相连通的虹吸结构，注水口与虹吸结构在水平面中的投影相交错排布；优选的，注水口处于投放盒的第一端的上方，虹吸结构处于投放盒的第二端处。
进一步，注水盒的顶壁下方扣合有分水板，分水板与注水盒顶壁共同围成注水腔。
进一步，投放盒内设有多个投放腔，注水盒的顶部设有与各投放腔一一对应设置的注水腔，各注水腔分别设有与注水盒外部相连通的进水口。

如图1至图8所示，本发明实施例中介绍了一种洗衣机注水盒结构及洗衣机，所述注水盒结构包括固定安装于洗衣机上的注水盒100；洗衣机进水管流入的进水水流流入注水盒100，注水盒100流经的水经出水口注入洗衣机的桶内，对桶内盛放的负载进行浸湿、洗涤等处理。同时，注水盒100上安装有可抽拉的投放盒200，投放盒200内具有供洗衣粉、洗涤剂、增香剂、消毒剂等添加物投放的投放腔15，流经注水盒100的洗衣机进水水流中的至少部分流经投放腔15，将投放腔15内的待添加物随水流一并冲入洗衣机桶内、对桶内负载进行处理。
本发明实施例中，所述的洗衣机优选的为波轮式洗衣机，波轮式洗衣机的外壳上部设有控制盘座，外壳内安装有顶部开设桶口的外桶，外桶内安装有可 受电机驱动旋转的内桶，内桶中还可以安装有可独立旋转、可与内桶共同旋转的波轮。所述的注水盒100安装于波轮式洗衣机的控制盘座上，控制盘座的中部设有与桶口对应开设的衣物投放口，注水盒100的前端与衣物投放口相对应连通，注水盒100的出水口朝向下方，使得注水盒100出水口流出的水流可直接经内桶桶口喷射至内桶内部，进而实现洗衣机经注水盒100向桶内进水的目的。
如图4至图8所示，本发明实施例中，注水盒100包括壳体1，壳体1内部中空构成供洗衣机进水水流流经的腔室；壳体1底部设有出水口2，壳体1内部流入的洗衣机进水水流经出水口2流出、流向洗衣机桶内。
本发明实施例中，所述的注水盒的壳体1可以为仅前端具有开口的壳体结构，使得开口可供投放盒200自前向后插入注水盒100、或自后向前拉出注水盒100，令注水盒100的顶壁由壳体1的顶部构成(未在附图中注明)；同时，本发明实施例中，注水盒100的壳体1还可以设置为上端敞口的结构，使得注水盒100安装于控制盘座上，利用控制盘座对应封闭壳体1的上端敞口，使注水盒100的壳体1内部所形成腔室的顶壁由控制盘座构成，令注水盒100的顶壁由控制盘座构成，依然可实现将注水盒的壳体1围成仅前端开口、供洗衣机进水水流流经的腔室结构的目的。
本发明实施例中，洗衣机注水盒100的顶部设有注水腔16，注水腔16上设有进水口，所述进水口与洗衣机进水管相连通，以将洗衣机进水水流引流导入注水腔16中；一般的，注水腔的进水口设置于注水盒的顶壁上，以由上向下进水(未在附图中注明)。同时，注水腔16的底部设有向下开设的注水口18，注水口18与投放盒200上设置的投放腔15相连通，使得注水口18可将导入注水腔16的进水水流流至投放盒200的投放腔15中，利用进水水流冲刷投放腔15 内的添加剂，实现添加剂随进水水流一并进行投放的目的。
本发明实施例中，注水腔16处于投放盒200的上方，使得投放盒200抽拉位移时与注水腔16互不干涉，又能使得注水腔16自注水口18流出的水流可受重力作用而直接流向投放盒200上所设的投放腔15内。
本发明实施例中，注水腔16的底部设有向投放盒200内注入进水的注水口18；注水腔16内还设有不经投放盒200、与注水盒100中空腔室直接连通的溢水口19。
本发明中，通过在注水腔16上开设溢水口19，使得投放腔流经的进水水流可自溢水口19进行分流，还有，通过设置溢水口19，使得注水腔16可经溢水口19与外部相连通，使得注水腔16内气压与注水盒100内腔室相保持一致，以实现对注水腔16内气压进行相应调节的目的；同时，通过在注水腔16上开设专门的溢水口19，可对溢水水流进行引流，避免注水盒100的进水流速过急时、自注水盒100顶部向外周扩散溢流情况的发生。
如图4至图8所示，本发明实施例中，注水盒100的顶部设有分水板300，分水板300直接扣合于注水盒100的顶壁、或对应覆盖注水盒100的顶部部分敞口设置，使得分水板300与注水盒100顶壁、或分水板300与控制盘座内壁共同围成注水腔16。
本发明实施例中，注水腔16的注水口18和溢水口19分别设于注水腔16沿投放盒200抽拉方向的相对两端；优选的，投放盒200可前后方向抽拉的安装于注水盒100中，注水口18设于注水腔16的第一端，第一端为注水腔16朝向投放盒200拉出方向的一端；溢水口19设于注水腔16的第二端，第二端为注水腔16朝向投放盒200推入方向的一端；进一步优选的，所述的第一端为朝向洗衣机前侧的一端、第二端为朝向洗衣机后侧的一端。从而，使得溢水口19 与注水口18相远离设置，最大化的避免二者产生相互干涉。
本发明实施例中，注水盒的注水腔16部分处于投放盒200的上方、部分与投放盒200相交错排布，以使得注水腔16自注水口18正常注入的进水水流经投放盒200再流入注水盒100的腔室中，利用进水对投放盒200中添加剂进行投放；还能使自溢水口19流出的溢流水流可直接流入注水盒100中，以避免注水盒产生外溢水流而影响添加剂投放的问题产生。
优选的，本发明实施例中，投放盒200内具有顶部敞口的、供添加剂投放的投放腔15，注水腔16的注水口18设于投放腔15的顶部敞口的相对上方，以使得注水口18注入的进水水流可直接注入投放腔15中，进而达到对投放腔15内添加剂进行冲刷投放的目的。
同时，本发明实施例中，投放盒200的推入端与注水盒100的内壁之间具有一定间距空间22，注水腔16的溢水口19设于投放盒与注水盒100之间间距空间22的上方，溢水口19流出的溢水水流直接经间距空间22注入投放盒200下方的注水盒100腔室中，以使注水腔的溢水水流直接经注水盒100腔室进行投放。
本发明实施例中，投放腔15内设有将投放腔15内部与投放盒200下方的注水盒100底部空间相连通的虹吸结构23，注水口18与虹吸结构23相交错排布；优选的，注水口18处于投放盒200的拉出端的上方，虹吸结构23处于投放盒200的推入端处。
如图4至图8所示，本发明实施例中，注水腔16内的中部设有沿投放盒200推拉方向延伸的分割筋17，分割筋将注水腔16分为左右两部分20、21，左右两部分20、21的第一端经分割筋17分为相独立的区域、而左右两部分20、21的第一端经分割筋17与注水腔16之间的间隙相连通，以使得注水腔16内形成 弯曲回折的流道26。注水腔16的进水口与注水腔16的左部分20的第二端的顶部相连通、溢水口19设于注水腔16的右部分21的第二端的底壁处；注水腔16的左部分20的第一端、和/或右部分21的第一端、和/或二者相连通处的腔室底壁上排布有多个上下贯通开设的注水口18。
从而，使得注水腔16内形成一弯曲回折的流道26，并在流道26的两端部分别设置进水口和溢水口19，使得溢水口19最大化的远离注水腔16的进水位置，避免误排放溢水水流的现象发生；同时，将注水口18设于弯曲回折流道26的弯折处，以使得注水腔16中的进水水流可受注水腔16内壁及分割筋17的导流作用而改变流向、引导注水腔16中水自注水口18流出。
如图4至图8所示，本发明实施例中，所述分割筋17在投放盒200抽拉方向上的延伸长度小于注水腔16的延伸长度；分割筋17的一端与注水腔16的第二端相密封连接、另一端与注水腔16第一端相间隔设置，以使得注水腔16的进水口和溢水口19经分割筋17相隔离，进而实现溢水口19与注水腔16的进水位置距离最大化设置的目的。
同时，优选的，本发明实施例中，分割筋17的凸出高度低于、或等于注水腔16的高度，以使得进水过急时可令注入注水腔16的部分水流跃过分割筋17而分流至另一部分中，以实现对进水水流进行调压、自注水口18流出的注水水形保持稳定的效果。
如图8所示，本发明实施例中，所述的分割筋17设于分水板300上，分割筋17为自分水板300上侧面向上凸出延伸的竖直档筋；优选的，分割筋17与分水板300一体设置。
本发明实施例中，为了提升注水口18流出水流的压力、引导注水腔16中进水向注水口18处汇聚流动，进行如下设置：注水腔16的左部分20的底壁为 自第二端向第一端方向逐渐向下倾斜的斜面，以使得自进水口流入注水腔16中的进水水流可受重力引导而向注水口18处汇聚流动。而本实施例中，为了使得流入注水腔16中的水流可自个注水口18均匀的喷出，将注水腔16的右部分21的底壁设置为自第二端向第一端方向逐渐向下倾斜的斜面，以使得整个流道26的底壁均为沿水流方向逐渐下倾的斜面，以调节沿水流方向排布的各注水口18的水压、使其保持一致。
优选的，本发明实施例中，还可以将注水腔16的右部分21的底壁也设置为自第二端向第一端方向逐渐向下倾斜的斜面，以避免注水腔16内产生残留水(未在附图中注明)。
如图6所示，本发明实施例中，注水腔16的右部分21的底壁开设有上下贯通的开孔，所述开孔构成溢水口19；所述的溢水口19为自外周向中心逐渐向下弯曲的倒锥形开孔，以便于水流外排。
如图7所示，本发明实施例中为了防止注水腔16中未触发溢流的进水自溢水口19外流而降低注水口18出水压，可以进行如下设置：注水腔16的右部分21的底壁的开孔处设有向上延伸的一圈挡水环24，挡水环24的高度低于注水腔16的顶壁、高于注水口18的高度设置，所述开孔及挡水环24的中空部共同构成溢水口19。通过上述设置，使得溢水口19的高度高于注水口18，以避免注水腔16内进水自溢水口19处产生误溢流情况的发生、进而增大注水口18处的出水水压。
优选的，本发明实施例中，为了进一步防止溢水水流向其他方向扩散、尤其是流入投放腔15而干涉添加剂投放，还可进行如下设置：
如图6和图7所示，分水板300的下方设置有处于溢水口19外周的、向下凸出的一圈导水环25，以引导自溢水口119流出的溢水水流经间距空间22直接 流向注水盒100的下部空间；进一步优选的，导水环25的底端低于投放盒200的顶壁、对应伸入投放盒200与注水盒100之间的间距空间22中，以避免溢水水流流入投放盒200情况的发生。
如图4至图8所示，本发明实施例中，投放盒200内设有多个投放腔15，注水盒100的顶部设有与各投放腔15一一对应设置的注水腔16，各注水腔16分别设有与注水盒100外部相连通的进水口。优选的，投放盒200内设有多个投放腔，各投放腔15沿与投放盒200抽拉相垂直的方向、即洗衣机的左右方向依次排布，注水盒100的顶部设有多个、与各投放腔15一一相对设置的注水腔16，至少一个注水腔16采用上述的结构进行设置；进一步优选的，各注水腔16分别由不同的分水板300构成，至少一个分水板300围成上述结构的注水腔16。
如图1至图3所示，本发明实施例中，注水盒的壳体1底部设有引导壳体内水流向出水口2、增大出水水压的引流增压结构。
通过在注水盒底部设置引流增压结构，使得注水盒出水口处的水压增大，实现自出水口流出水流向左右两侧发散，令水盒流入桶内的水流形成瀑布形，进而实现经注水盒流入洗衣机桶内的进水水流覆盖面积增大、使桶内盛放的大部分负载可有效浸湿，进而可大大提升洗衣机的洗涤效果。
如图1至图3所示，本发明实施例中，引流增压结构包括：壳体1的底部设有向下凹陷的引水槽3，引水槽3的最低处与注水盒的出水口2相连通。通过在壳体1底部设置引水槽3，使得壳体1内部的水在引水槽3的引导作用下向注水盒的出水口2处汇聚，以使得注水盒出水口2处的水压增大，进而提升出水发散效果，使注水盒流入桶内的水流形成瀑布形、增大洗衣机进水水流的覆盖面积；同时，通过上述引水槽3的设置，使得注水盒内水流可全部经出水口2外排，有效避免注水盒内水的残留。
本发明实施例中，出水口2设于引水槽3前侧的壳体底壁11上，出水口2为沿注水盒左右方向延伸的、朝向下方开设的条形开口。引水槽3的底壁为沿注水盒的前后方向、向出水口2侧逐渐下倾的斜面。引水槽3的前端敞口设置、与出水口2直接相通。通过上述设置，在引水槽3倾斜底壁的引流作用下，使得引水槽3内的水可在重力作用下加速向出水口2方向流动，并在流动过程中因自身重力作用而增大流速，使得出水口2处水压进一步增大、令出水水流形成的瀑布水形更为稳定。
本发明实施例中，引水槽3的底壁为自注水盒的左右两侧向中心逐渐下降的曲面，使得引水槽3与注水盒相连处的底壁为左右两端高、中间低的弯曲部，以使得自引水槽3左右不同位置流向出水口2的水流流速不同，进而实现注水盒出水口2流出水流向两侧发散、形成瀑布状出水水形的效果。
如图1至图3所示，本发明实施例中，引流增压结构还包括：注水盒的前端设有前后间隔排布的防水板4和挡水板5，防水板4和挡水板5之间的间隙构成出水腔6；出水腔6下侧所对应的壳体1底部镂空设置、构成注水盒的出水口2；挡水板5的中部开设豁口，豁口与引水槽3的前端敞口相对开设，引水槽3经豁口直接与出水腔6相连通。在注水盒的前端设置由挡水板5和防水板4、及水盒左侧壁12、右侧壁13共同围成的出水腔6，出水腔6下端的注水盒底壁11全部镂空设置以构成注水盒的出水口2，使得注水盒的出水口2设置于独立的出水腔6处，在保证出水水流可全部引导至出水口2实现顺畅外排的前提下、还可有效阻挡出水水流自注液盒前端溢流。
尤其是，在水盒内安装有可自前侧向外抽出的投放盒时，注水盒的出水水流容易溅射至投放盒前端面板情况的发生，就会使用户在下次抽拉投放盒进行洗衣粉、洗衣液等添加物投放时造成沾染，影响用户体验。而通过在出水口2 的前后两端分别设置防水板4和挡水板5，就可对出水水流进行有效遮挡，进而避免出水水流向上方的投放盒处进行溅射情况的发生。
同时，本发明实施例中，注水盒底部所设的防水板4和挡水板5的下端均低于注水盒壳体1的底壁11；优选的，防水板4和挡水板5的下端均低于引水槽3的最低点。同时，挡水板5和防水板4的上端均高于注水盒壳体1的底壁11；优选的，挡水板5和防水板4的上端均高于注水盒底壁所设凸出部7的顶面，以实现对注水盒进水的有效遮挡。
还有，本发明实施例中，如图1和图2所示，引水槽3与出水口2相连的敞口端与注水盒的左、右侧壁12、13分别相间隔一定距离，在引水槽3敞口端的左右两侧的注水盒的底壁11上分别设有一段挡水板5，两段挡水板5与注水盒的左、右侧壁12、13分别一一相对的密封相连，以有效阻挡注水盒内水流自非引水槽3处流至出水口2、进而提升注水盒的出水水形稳定性。
此外，由于引水槽3的敞口端的左右宽度小于出水口2的左右宽度，使得由引水槽3流至出水口2的水流可具有一定的左右发散空间，进而保证出水口2处的出水水流不会被注水盒的左、右侧壁12、13阻挡，进一步保证出水水流的瀑布形水形结构的稳定性。
如图1至图3所示，本发明实施例中，防水板4为自左右两端向中部、逐渐向注水盒内弯曲的曲面构成；优选的，出水口2各处在注水盒前后方向上的宽度均保持一致。从而，使得出水口处的水流在上述孔形结构的作用下，向出水口左右两侧发散，进而使得注水盒的出水水流形成瀑布型水形的效果。
本发明实施例中，所述的挡水板5和防水板4均与注水盒的壳体1一体设置。
如图1至图3所示，本发明实施例中，引流增压结构还包括：注水盒的壳体1的底壁11设有向上凸出的、处于左右两侧的凸出部7，两凸出部7之间间隔设置、间隔处构成供注水盒内水流流动的流道8，流道8的一端经注水盒的后侧壁14封堵，使得靠近封堵端的流道8部分构成聚水部10；流道8的另一端与引水槽3相接，以引导流道8中的水向引水槽3方向流动。通过在注水盒的壳体1底部设置上述凸出部7，令注水盒底壁11上形成一向下凹陷的流道结构，使得注水盒内进水水流可在流道8的引导作用下流向注水盒的出水口2处，进而保证注水盒中的水流顺畅性。
同时，本发明实施例中，为了进一步提升水流顺畅性，进行如下设置：
如图1至图3所示，左右两侧的凸出部7相对注水盒的前后轴线对称排布，使得两凸出部7之间间隙形成的流道8沿注水盒的轴线前后方向延伸，流道8的前端与引水槽3的后端、最高处相通，流道8的后部构成供注水盒进水流入的聚水部10。还有，流入注水盒内部腔室中的水流自注水盒后端流入，使得流入水流可直接流至聚水部10处，进而保证注水盒内水流可沿流道进行顺畅流动、实现注水盒进水水流沿壳体1底部所设流道8向出水口2方向流动的效果。
本发明实施例中，聚水部10的左右宽度大于引水槽3左右方向最宽处的宽度，以使得流道8可自大口端进水、小口端出水，实现注水盒内水流经流道8进行加压处理、进一步提升注水盒出水口2处出水水压的目的。
本发明实施例中，为了进一步提升注水盒出水口2处的出水压力，进行如下设置：
如图1至图3所示，流道8的至少部分为向引水槽3方向逐渐收窄径向宽度的缩口段9，以在流道8上设置沿水流方向收窄的缩口段9，使得流道可对流 经水流进行加压处理，可有效提升注水盒出水口2处的出水水压，进而保证注水盒出水口2处可形成稳定的瀑布状出水水形的效果。
优选的，本发明实施例中，流道8的缩口段9的左右侧壁均为沿注水盒前后方向、逐渐向中心倾斜的斜面，使得缩口段9由沿注水盒轴向对称设置的锥形流道构成。
如图1至图3所示，本发明实施例中，引水槽3的至少部分处于流道8的前端部内，引水槽3的后端、最高处处于流道缩口段9的小口处。从而，使得自流道8流出的水流可全部流入引水槽3中；还有，流道8中经缩口段9进行加压处理的水流直接流向引水槽3，以最大化的提升注水盒出水口2处的出水水压。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，上述实施例中的实施方案可以进一步组合或者替换，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
