具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
参考图12所示的示意图，所述洗衣机包括烘干***24和进水***25，其中，烘干***24包括安装有过滤网的用于烘干循环风流动的风道2，进水***25的进水结构设置在风道2内并靠近过滤网设置，以能够在向洗衣机进水的同时清洗过滤网。
这样，由于进水***25的进水结构设置在洗衣机的烘干***24的风道2内并靠近过滤网，比如如图所示的第一过滤网22和第二过滤网23，这样，洗衣机通过进水结构进水的同时，进水结构可以过滤网进行自清洗，从而不用人工将过滤网拆卸清洗，从而将洗衣机的进水***25和烘干***24相结合，保证了过滤网能够得到及时有效的自清理，确保烘干外循环的风量，提升了烘干效率，提升了洗衣机使用的便捷性和智能化。
进一步地，如图12所示的，风道2的吸风口1和洗衣机的滚筒外筒之间连接的吸风管12用作洗衣机的进水管，这样，吸风管12就能够起到双 重作用，在烘干阶段，其起到通风作用，而在注水洗涤阶段，其起到进水作用，这就简化了洗衣机的内部结构。同时，吸风管12还可以用作对过滤网进行清洗的回流水的回流管，也就是，对过滤网清洗的回流水将回流至吸风口1处，然后通过吸风管12回流到滚筒外筒内，以用作洗涤用水。
当然，本发明的洗衣机中，如图7、8和12所示的，烘干***24的热泵壳体包括热泵底壳13和热泵盖板14，热泵底壳13和热泵盖板14之间形成风道2的一部分；其中，进水***25包括形成在热泵盖板14上的进水水道15，上述的进水结构和进水水道15连通。这样，热泵盖板14上的进水水道15接通自来水，自来水通过进水结构向洗衣机注水的同时对过滤网进行自清洗。
具体的，热泵底壳13内形成有位于风道2内的滤网安装部，比如图8所示的第一过滤网安装部3(第一过滤网22安装在其上)和第二过滤网安装部7(第二过滤网23安装在其上)；这样，热泵盖板14上形成有进水水道15，进水水道15上设置有进水结构；其中，进水结构靠近滤网安装部设置，使得进水结构喷出的水能够对安装在滤网安装部上的过滤网进行清洗，从而洗衣机在进水的同时，能够使得进水对过滤网进行自清洗，这保证了过滤网能够得到及时有效的清理。
进水结构可以具有多种结构形式，例如，一种结构形式中，进水结构可以为设置在风道2内的与进水水道15连接的喷嘴，这样，喷嘴可以对过滤网进行清洗。
或者，另一种结构形式中，为了简化结构，并充分利用进水水道15的水道壁，优选地，如图8和9所示的，进水结构为形成在进水水道15的朝向滤网安装部的水道壁16上的喷淋孔17。这样，在自来水的自身压力下，进水水道15内的水将从喷淋孔17中喷出而喷淋在过滤网上以自清洗过滤网，同时，喷淋孔17的设置可以避免在风道2内设置其他的喷淋部件而影响风道2内吸风面积。
进一步地，喷淋孔17的数量和布置方式可以根据实际需求来选择，例如，如图7、9、10和11所示的，在进水水道15的高度方向上，形成有多排喷淋孔17，每一排喷淋孔的个数为多个。这样，通过多排喷淋孔，以及每排上的多个喷淋孔，可以对过滤网从上到下进行更有效的自清洗。
进一步地，为了使得多排喷淋孔17能够充分清洗过滤网，优选地，如图8和9所示的，进水水道15的朝向滤网安装部上的过滤网的水道壁16倾斜布置。这样，每排喷淋孔17喷射的喷淋水流将直接喷淋在过滤网的网面上，以进行更有效的清洗。
另外，在多排喷淋孔中，为了更全面清洗过滤网，每排喷淋孔具有不同的喷淋位置，例如，一种结构形式中，如图8和12所示的，上排喷淋孔靠近滤网安装部上的过滤网设置以能够对安装在过滤网安装部上的过滤网从最上部往下冲洗，下排喷淋孔远离滤网安装部上的过滤网设置以能够对安装在过滤网安装部上的过滤网的中下部冲洗。这样，多排喷淋孔的喷淋位置的侧重点不同，从而更全面的喷淋清洗过滤网。
当然，可以通过调整喷淋孔的大小，或者倾斜角度来实现，例如，如图9所示的，上排喷淋孔17的下侧表面和水平面之间的夹角小于下排喷淋孔17的下侧表面和水平面之间的夹角。这样，上排喷淋孔17的喷淋水更易于从过滤网的上部往下清洗，而下排的喷淋孔17更易于喷淋清洗过滤网的中下部。
另外，热泵盖板14可以通过多种形式来形成进水水道15，比如，一种结构形式中，热泵盖板14的外板面或者内板面上可以固定设置有进水管，然后，进水管连接有喷嘴；
或者，如图10和11所示的，进水水道15为U形水道，U形水道的两个直水道18上设置有进水结构，例如，直水到18的倾斜布置的水道壁16上形成有多排喷淋孔17，这样，通过直水道18，更易于全面清洗过滤网。进一步地，如图8、10和11所示的，热泵盖板14的外板面19上形成有水 道凹槽20，比如，U形水槽，水道凹槽20上盖合有水道盖板21以形成进水水道15。
当然，如图11所示的，进水水道15的起始端形成有进水口，而末端则形成有能够伸入到热泵底壳内的过滤网之间的汇流通道的角落内的喷淋柱，该喷淋柱上形成有朝向角落的出水孔，以对角落进行清洗，避免毛屑在死角堆积。
另外，如图1和3所示的，热泵底壳13上的滤网安装部包括第一过滤网安装部3，使得过滤网包括安装在第一过滤网安装部3上的第一过滤网22，其中，风道2的位于第一过滤网22一侧的风道壁上形成有回流水入口4，并且风道2的位于第一过滤网22另一侧的风道壁上形成有回流水出口5，热泵底壳13上设置有将回流水入口4和回流水出口5连通的回流通道6。
这样，由于风道2的位于第一过滤网22两侧的风道壁上分别形成有回流水入口4和回流水出口5，并且回流水入口4和回流水出口5通过回流通道6连通，这样，洗衣机进水***25的热泵盖板14上的多排喷淋孔17可以对安装在第一过滤网安装部3上的第一过滤网22进行冲洗，如图8所示，此时，第一过滤网安装部一侧(比如，冲洗第一过滤网时渗入到第一过滤网一侧，和/或冲洗第二过滤网的)的冲洗水可以通过回流水入口4、回流通道6和回流水出口5回流，比如回流至吸风口1，然后通过吸风管12进入到滚筒内，而第一过滤网安装部3另一侧的冲洗水可以直接流至吸风口1，然后通过吸风管12进入到滚筒内，从而避免冲洗水在第一过滤网安装部3的一侧集聚。
在此需要说明的是，此处的第一过滤网安装部3并不限于图1中所示的一个，应当理解，第一过滤网安装部3可以为沿着风道2间隔布置的多个，这样可以布置多个第一过滤网，比如两个第一过滤网安装部3，从而可以安装两个第一过滤网，从而每个第一过滤网一侧比如两个第一过滤网之间的回流水都可以通过各自的回流水入口4流向回流通道6。
进一步地，如图1、图2和图3所示的，风道2形成有与第一过滤网安装部3间隔布置的第二过滤网安装部7，使得过滤网包括与第一过滤网22间隔布置的第二过滤网23，其中，回流水入口4位于第一过滤网安装部3的第一过滤网22和第二过滤网安装部7的第二过滤网23之间。这样，对设置在第二过滤网安装部7上的第二过滤网23冲洗的水可以通过回流水入口4和回流通道6回流，此时，第二过滤网安装部7可以为一个，使得沿着吸风方向，第二过滤网23位于一个第一过滤网22(如图3所示)或者多个间隔布置的第一过滤网22的下游侧。这样，洗衣机的进水***可以在进水的同时对多层过滤网同时进行清洗，或者专门对多层过滤网同时进行清洗，而下游侧的冲洗水则可以通过回流入口4流至回流通道6以回流。
进一步地，为了便于第一过滤网22一侧的冲洗水尽快回流，优选地，如图1所示的，风道2位于第一过滤网安装部3和第二过滤网安装部7之间的底壁部8形成为U形集水槽。这样，在该U形集水槽的收集作用下，冲洗第二过滤网的冲洗水和/或冲洗第一过滤网时从第一过滤网渗透的冲洗水将被U形集水槽收集，并随后通过回流水入口4流入到回流通道6内。
更进一步地，为了更便于冲洗水回流，优选地，风道2位于第一过滤网22和第二过滤网23之间的底壁部8和回流通道6沿着回流水的方向连续倾斜向下延伸。这样，由于连续倾斜布置，底壁部8比如U形集水槽内的冲洗水将快速通过向下回流通过回流通道6，然后从回流水出口5排出。
另外，为了不占用热泵底壳的内部空间，优选地，如图1所示的，回流通道6位于风道2的外部。这样，由于回流通道6位于风道2的外部，从而并不占用风道2的任何内部空间，并不对洗衣机的烘干***的换热单元的换热面积造成影响，同时也不对过滤网的通风面积造成影响。
当然，本发明的热泵底壳中，回流通道6可以通过一位于热泵底壳外部的管道形成，例如，管道的一端连接于回流水入口4，另一端连接于回流水出口5；
或者，为了提升结构的稳定性，如图1和4所示的，风道2的风道侧壁包括向外伸出的伸出部9，回流通道6形成在伸出部9内。这样，由于伸出部9为风道2的风道侧壁的一部分，从而可以一体注塑形成热泵底壳以及回流通道6，从而避免外接管道来形成回流通道6。
另外，回流通道6也可以直接形成在风道2的风道侧壁内部，也就是，风道2的风道侧壁并不向外伸出，而在其内部就形成回流通道6。
当然，回流通道6可以具有多种结构形式，比如为U形通道，以便于回流水及时回流。
另外，为了便于回流，也便于洗衣机的进水，如图2所示的，吸风口1形成在风道2的位于第一过滤网安装部3另一侧的风道底壁10上，回流水出口5和吸风口1连通。这样，通过回流水出口5的回流水即可流入到风道底壁10上而通过吸风口1流入到洗衣机的滚筒内，同时，对最上游的第一过滤网的冲洗水直接可以通过该吸风口1顺畅地回流。
另外，如图3所示，由于多个第一过滤网22或者第一过滤网22和第二过滤网23为串联，洗衣机的烘干***24运行时，外循环空气必须依次通过各个过滤网过滤，因此，为了提升过滤效果，如图3所示的，回流水出口5处设置有单向挡板11，其中，单向挡板11设置为仅在通过回流通道6回流的回流水的作用下将回流水出口5打开。这样，如图5所示，烘干***24运行时，吸风口1在烘干***的风机作用下开始进风，单向挡板11可以在自重闭合的作用以及外循环空气的流向压力作用下而封闭回流水出口5，以阻挡外循环空气依次通过各个过滤网，而防止部分外循环空气通过回来通道6而绕过上游的过滤网；而在洗涤阶段，或者冲洗过滤网阶段，如图6所示的，洗衣机的进水***进水的同时对各个过滤网进行清洗，而单向挡板11则可以在回流水的流向压力下开启，以将回流水出口5打开，以允许回流水顺利导出并通过吸风口1流入到滚筒内。
这样，洗衣机在进水的同时，可以利用进水***比如进水结构的进水 对过滤网进行自清洗，从而并不需要人工将过滤网从机器内取出清理，也就是，每次进水的同时都会对过滤网进行自清洗，这保证了过滤网能够得到及时有效的清理，同时，通过单向挡板11，更进一步地确保烘干外循环的风量，提升了烘干效率。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
