Description

洗衣机的烘干系统以及洗衣机 技术领域
本申请涉及家电生产技术领域，例如涉及一种洗衣机的烘干系统以及洗衣机。
背景技术
相关技术中的洗衣干衣机可以分为三种：第一种为简单的直排式，风机将加热管输出的热风通过烘干加热通道吹入内筒，热量使衣物的水蒸发变成蒸汽，将湿热蒸汽排到室内；第二种为风冷、水冷式，风机将加热管产生的热量通过烘干加热通道吹入内筒，热量使衣物的水蒸发变成蒸汽，通过风冷或水冷方式将湿热蒸汽冷凝；第三种为热泵系统，湿热蒸汽经过蒸发器冷凝出水，工质从蒸发器经压缩机传到冷凝器，在冷凝器中释放热量将空气加热。
但是，无论选择何种加热和冷凝方式，在烘干过程中，内筒中衣物的线屑均会被烘干时风机产生的风带到烘干通道和风道中，在风机处堆积，线屑的堆积使得烘干通道的风量降低，导致热交换效率降低，从而降低了烘干效率，造成烘干时间延长，烘干能耗增加，甚至衣物无法烘干。

具体实施方式
下面通过实施例并结合附图对本申请做详细描述。
实施例一
本实施例提供了一种洗衣机及洗衣机的烘干系统，该洗衣机可以为洗衣烘干一体机，如图1所示，该洗衣机的烘干系统包括加热装置10、风机20、外筒30、风道40以及接口50，风道40的一端通过接口50与外筒30连通，风道40的另一端与风机20连接。风机20与加热装置10连接，以 将加热装置10加热的气流通过风机20经风道40吹入外筒30内，进而进入内筒，实现衣物的烘干。
如图2-7所示，本申请实施例的烘干系统还包括过滤装置60，过滤装置60包括滤网61以及清洗部62。滤网61上设置有过滤孔，清洗部62上设置有清洗通道。清洗通道的出口端621位于滤网61所在位置处，且在出口端621处形成预设出水压力。也就是说，当介质经清洗通道的出口端621流出时，具有一定的压力，可以以喷射的方式喷射至滤网61。介质可以为水，也可以为任意一种清洗剂。
上述结构，在风道40内增加过滤装置60，且过滤装置60包括滤网61与清洗部62，在烘干过程中，当内筒中衣物的线屑被带到风道40中时，会被滤网61拦截，防止线屑在风机20处堆积，且通过清洗部62能够将滤网61上的线屑清洗干净，避免滤网61堵塞，进而保证风机20、风道40以及烘干通道的畅通，提高热交换效率和烘干效率，缩短烘干时间，降低烘干能耗，以保证衣物烘干的效果。
一实施例中，滤网61可以为曲面结构，如滤网61为向风机20凸出的凸面结构，或者向远离风机20的一侧凸出的凸面结构，滤网61也可以为平面结构。在滤网61为平面结构时，清洗通道的出口端621的介质流向可以与滤网61平行，也可以与滤网61呈一夹角，出口端621可以位于滤网61的一侧(如图3所示)，也可以沿滤网61的延伸方向位于滤网61的一侧(图中未示出)。
一实施例中，清洗部62包括清洗管622和分水盘623，清洗管622与分水盘623连接，二者可以直接连接，也可以间接连接。清洗通道设置于清洗管622内，出口端621的介质流向指向分水盘623。也就是说，清 洗管622的内部形成清洗通道，清洗通道的一端为入口端624，清洗通道的另一端为出口端621。此时，滤网61安装于分水盘623上，通过设置清洗管622与分水盘623，使出口端621喷出的介质流喷射至分水盘623，分水盘623能够将介质流分流至多个方向，进而使介质流到达滤网61的多个位置，从而提高对滤网61清洗的干净度。
一种结构，分水盘623为平板结构，如图6-7所示，为了使喷射至分水盘623上的介质流的压力增大，以起到更好地分流作用，出口端621的介质流向与分水盘623垂直设置，至少一段清洗管622可以靠近出口端621与分水盘623垂直设置，也可以整个清洗管622与分水盘623垂直设置。可以理解地，分水盘623也可以与清洗管622倾斜设置，这样，出口端621的介质流向与分水盘623呈一锐角，能够缓和介质流对分水盘623的冲击。
另一种实施例，如图4-5所示，分水盘623呈凸起结构，分水盘623向出口端621所在的一侧凸出，即至少分水盘623靠近出口端621的一面向出口端621所在的一侧凸出。可选地，出口端621与凸起结构的波峰位置相对，此时，滤网61安装于分水盘623的外周，即滤网61可以呈环形结构，套设于分水盘623的边缘，或者滤网61由多个子网611构成，每个子网611沿分水盘623的周向分布(如图3所示)。采用这种凸起结构，能够使介质流沿着凸起结构的表面流动，进而能够使介质流的分流更均匀，图4中滤网61上的箭头示出了介质流的流向。
一实施例中，凸起结构从边缘向中心逐渐向出口端621所在的方向凸起，即凸起结构可以为伞状结构、球冠结构或者锥形结构。为了使分流更均匀，进而使介质流能够冲刷至滤网61的每个位置，分水盘623为球冠结构，出口端621的介质流向沿球冠结构的径向设置。
一实施例中，不论分水盘623采用何种结构，滤网61均可以沿分水盘623的周向设置。滤网61也可以设置于分水盘623的一处，此时，分水盘623可以沿出口端621指向滤网61的方向延伸，以将出口端621的介质流导向滤网61。
上述实施例中，为了保证分水盘623的分水效果，需要保证分水盘623与出口端621的安装位置，为此，过滤装置60还包括定位机构63，清洗管622通过定位机构63与分水盘623连接。其中，定位机构63可以包括定位杆。如图3所示，定位杆的一端伸入清洗管622，可以与清洗管622连接，定位杆的另一端连接于分水盘623。一实施例中，定位杆的横截面为十字型结构，以尽可能增大定位杆与清洗管622之间的空间，增加过流面积。定位机构63也可以包括连接于出口端621的定位凸起和设于分水盘623的定位凹槽，定位凸起可以向清洗管622的内部凸出，也可以向清洗管622的外部凸出，定位凸起插入定位凹槽。此外，定位机构63与清洗管622、分水盘623的连接方式，可以为卡接、粘接或者螺钉连接。
在设有清洗管622与分水盘623时，尤其在滤网61安装于分水盘623的外周时，滤网61的一侧边缘与分水盘623连接，另一侧边缘会形成悬臂结构，在受到介质流冲刷时，会造成变形，降低过滤效果。为了解决上述问题，过滤装置60还包括安装架64，安装架64呈环形结构，分水盘623置于安装架64的内部，使安装架64与分水盘623之间形成环形腔。将滤网61设置于环形腔内，如图3所示，滤网61的两个边缘分别可以与安装架64、分水盘623连接，进而增加滤网61的强度，保证其过滤效果。
为了进一步增加滤网61的支撑强度，以及防止安装架64的变形，过滤装置60还可以包括设置于环形腔内的连接杆65，连接杆65的两端分别 连接于安装架64与分水盘623，通过增加连接杆65，能够对安装架64起到更好的固定作用，防止其由于重力作用造成与分水盘623的位置发生变化，造成滤网61的变形甚至拉破。在沿环形腔的环绕轴所在的方向，分水盘623的投影与安装架64的投影均为圆形结构、且两个投影同心设置时，连接杆65可以沿该圆形结构的径向设置。
上述连接杆65可以设有一个、两个、三个或者更多个。在连接杆65设有多个的情况下，多个连接杆65将环形腔分割为多个子腔。如图3-4所示，此时滤网61包括多个子网611，每个子腔均设置有一个子网611，且每个子网611的边缘沿其周向与其所在的子腔的腔壁连接，这样使每个子网611的面积变小，且每个子网611的边缘均有腔壁与子网611连接，能够进一步增加整个滤网61的强度，提高滤网61的抗冲刷能力，延长滤网61的使用寿命。每个子腔内也可以设有两个或者多个子网611。
在设有连接杆65时，尤其是连接杆65设有多个时，滤网61还可以设置于连接杆65远离清洗管622的一侧，滤网61与连接杆65之间可以留有间隔，这时，通过连接杆65的支撑定位作用，能够使滤网61的变形减小。
此外，清洗部62也可以仅包括清洗管622，清洗管622的内部形成清洗通道，出口端621直接指向滤网61。可以理解地，在这种实施方式中，滤网61也可以采用上述安装架64安装。
一般地，清洗通道位于滤网61靠近风机20的一侧，以防止介质流进入风机20内，影响风机20的工作。
不论过滤装置60采用哪种方式设置，过滤装置60均可以设置于风道40的任一位置处，通常，过滤装置60安装于风道40靠近风机20的一侧。 从而使介质流能够冲刷到整个风道40内的线屑，将这些线屑冲刷至风道40远离风机20的一端，直至线屑进入内筒与外筒30之间的线屑收集器，然后排出洗衣机的外部。
实施例二
本实施例提供了一种洗衣机及洗衣机的烘干系统，其与实施例一中的洗衣机及洗衣机的烘干系统的区别在于过滤装置60的清洗部62的结构不同。
一实施例中，如图8-10所示，实施例的清洗部62包括安装盘625和进水管626，滤网61安装于安装盘625上，安装盘625的内腔与进水管626的内腔连通以形成清洗通道。清洗通道的出口端621位于滤网61的一侧，即沿着滤网61的延展方向，出口端621位于滤网61的一侧，以使流经清洗通道的介质流由滤网61的侧方流动至滤网61，进而对滤网61进行冲刷。上述介质流的介质可以为水，也可以为任意一种清洗剂。
本实施例中，过滤装置60可以设置于风道40的任一位置，可选地，过滤装置60设置于风道40靠近风机20的一侧。
为了更好地阻止线屑在风机20处堆积，安装盘625一般沿风道40的过流截面设置。此时，如果进水管626的延伸方向也沿着风道40的过流截面设置，则由于过滤装置60在垂直于过流方向的方向上的尺寸太大，不便于过滤装置60的布置，且会增加风道40的过流截面的尺寸，因此，进水管626可以与安装盘625垂直设置，即进水管626的延伸方向与安装盘625的盘面垂直，以解决上述问题。可选地，进水管626位于安装盘625靠近风机20的一侧，滤网61设置于安装盘625远离风机20的一侧，出 口端621位于进水管626与滤网61之间，以方便进水管626与外界的连接。一实施例中，进水管626与安装盘625也可以呈锐角设置。
一实施例中，滤网61可以为曲面结构，如滤网61为向风机20凸出的凸面结构，或者向远离风机20的一侧凸出的凸面结构，滤网61也可以为平板结构。在滤网61为平板结构时，清洗通道的出口端621的介质流向可以与滤网61平行，也可以与滤网61呈一夹角。可选地，出口端621的介质流向与滤网61的延伸方向相一致，尤其是在滤网61为平板结构时，经出口端621的介质流沿着滤网61的延伸方向喷射于滤网61上，如图9所示，图中滤网61上的箭头示出了出口端621的介质流向，以使介质流能够更好地冲刷滤网61。
上述实施例中的安装盘625包括安装框架6251，安装框架6251可以为环形结构，如圆环形结构、椭圆环形结构、矩形环结构。可选地，装框架6251采用圆环形结构，以便于加工以及增加安装框架6251的强度。滤网61设置于环形结构内，即滤网61的边缘沿其周向连接于安装框架6251内。如图8所示，通过环形结构，能够为滤网61提供更好地支撑力，进而避免滤网61由于冲刷力造成的破坏。
此时，出口端621可以设置于安装框架6251靠近风机20的一侧(出口端621不位于环形结构上)。可选地，出口端621直接设置于环形结构的环壁6251a上，即安装盘625的内腔设置于安装框架6251的环壁6251a上，安装盘625内腔靠近滤网61的一端设置有出口端621，安装盘625内腔的另一端与进水管626的内腔连通，通过将出口端621设置于环形结构的环壁6251a上，尤其在出口端621的介质流向与滤网61的延伸方向一致时，能够进一步减小过滤装置60的体积，且能够尽可能使介质流到 滤网61的所有区域，进而使滤网61被冲刷的更干净。
一实施例中，安装盘625的内腔包括变截面段，变截面段的过流面积沿介质流向增大，即在变截面段，安装盘625的内腔的过流面积沿着靠近进水管626的一端向出口端621的方向逐渐增大，以使安装盘625的内腔起到稳压作用，保证出口端621的介质流压力。

一实施例中，变截面段包括连接于环形结构的第一侧壁6283与第二侧壁6284，第一侧壁6283与第二侧壁6284呈V型结构，V型结构的大端形成出口端621，且第一侧壁6283、第二侧壁6284分别与环形结构的环壁6251a相切。也就是说，安装盘625的内腔的腔壁包括相对的第一侧壁6283与第二侧壁6284，第一侧壁6283、第二侧壁6284均与安装框架6251的环壁6251a相切，以使介质流能够沿第一侧壁6283、第二侧壁6284到达环壁6251a的每处，进而使滤网61被冲刷的更干净。
变截面段还包括连接第一侧壁6283与第二侧壁6284的第一底壁(图9和图10未示出)和第二底壁6286，沿风道20的风流方向，第一底壁与第二底壁6286相对设置，且第一底壁较第二底壁6286靠近风机20，即第一底壁、第一侧壁6283、第二底壁6286以及第二侧壁6284依次连接，形成安装盘625的内腔的变截面段。当第一底壁与第二底壁6286均为平面结构时，在变截面段的过流面积沿介质流向呈线性变化时，第一底壁与第二底壁6286平行设置；在变截面段的过流面积沿介质流向呈非线性变化时，第一底壁与第二底壁6286可以呈一非零夹角。一实施例中，第一底 壁与第二底壁6286也可以为曲面结构。
一实施例中，在变截面段的过流面积沿介质流向呈非线性变化时，在变截面段处，安装盘625的内腔可以呈圆锥台结构或者球台结构。
其中，在第一底壁为平面结构，滤网61为平板结构时，滤网61的一个平面与第一底壁共面。一实施例中，在第二底壁6286为平面结构时，滤网61的一个平面也可以与第二底壁6286共面。
安装盘625的内腔还可以包括等截面段，即安装盘625的内腔同时包括变截面段和等截面段，且变截面段较等截面段靠近出口端621，流入进水管626的内腔的介质流先经过等截面段再经过变截面段，然后流出出口端621，对滤网61进行冲刷。

不论安装盘625采用何种结构，出口端621可以为圆孔结构，也可以为扁嘴型结构(如图9所示)，在为扁嘴型结构时，能够增加出口端621的出水压力，进而使介质流能够对滤网61冲刷的更干净。在安装盘625包括环形结构的安装框架6251时，扁嘴型结构的长度方向沿着环形结构的环绕方向设置。
实施例三
本实施例提供了一种洗衣机及洗衣机的烘干系统，其与上述实施例所述洗衣机及洗衣机的烘干系统的区别在于：本实施例的过滤装置60的清洗部62的结构与上述实施例所述的装置60的清洗部62的结构不同。
本实施例中，如图11-18所示，过滤装置60包括滤网61和清洗部62。滤网61上设置有过滤孔，滤网61可以为平板结构，也可以为表面为曲面的板状结构。
本实施例的清洗部62也包括安装盘625和进水管626，区别在于本实施例的进水管626的延伸方向与滤网61的延伸方向相一致，即：进水管626向滤网61所在的方向延伸。安装盘625的内腔与进水管626的内腔连通以形成清洗通道，清洗通道的出口端621位于滤网61的一侧。通常，清洗通道的入口端624指向出口端621的方向，与滤网61的延伸方向一致。入口端624设置于进水管626的一侧，出口端621设置于安装盘625的一侧。在滤网61为平板结构时，进水管626的延伸方向平行于滤网61，以使流经清洗通道的介质流由滤网61的侧方流动至滤网61，进而对滤网61进行冲刷。上述介质流的介质可以为水，也可以为任意一种清洗剂。
上述结构，在风道40内增加过滤装置60，且过滤装置60包括滤网61与清洗部62，在烘干过程中，当内筒中衣物的线屑被带到风道40中时，会被滤网61拦截，防止线屑在风机20处堆积，且通过清洗部62能够将滤网61上的线屑清洗干净，避免滤网61堵塞，且设置进水管626向滤网61所在的方向延伸，能够使用于冲刷滤网61的介质流的流动更顺畅，进而保证风机20、风道40以及烘干通道的畅通，提高热交换效率和烘干效率，缩短烘干时间，降低烘干能耗，且保证衣物烘干的效果。
通常，安装盘625的盘面为平面，一实施例中，安装盘625包括安装框架6251，安装框架6251可以为环形结构，如圆环形结构、椭圆环形结构、矩形环结构。此时的盘面指环形结构的环面，可选地，盘面采用圆环形结构，以便于加工以及增加安装框架6251的强度。滤网61设置于环形 结构内，即滤网61的边缘沿其周向连接于安装框架6251内。如图11-12所示，通过环形结构，能够为滤网61提供更好地支撑力，进而避免滤网61由于冲刷力造成的破坏。
此时，出口端621可以设置于安装框架6251靠近风机20的一侧(出口端621不位于环形结构上)。可选地，出口端621直接设置于环形结构的环壁6251a上，即安装盘625的内腔设置于安装框架6251的环壁6251a上，安装盘625的内腔靠近滤网61的一端设置有上述出口端621，安装盘625的内腔的另一端与进水管626的内腔连通，通过将出口端621设置于环形结构的环壁6251a上，尤其在出口端621的介质流向与滤网61的延伸方向一致时，能够进一步减小过滤装置60的体积，且能够尽可能使介质流到滤网61的所有区域，进而使滤网61被冲刷的更干净。
一实施例中，清洗通道的内壁与环形结构的环壁6251a相切，以使由出口端621射出的介质流能够尽可能到达滤网61的每处边沿。
清洗通道包括相互连接的等截面段627和变截面段628，沿清洗通道的入口端624向出口端621的方向(即介质流向)，等截面段627的过流面积不变，变截面段628的过流面积增大，且变截面段628较等截面段627靠近出口端621，出口端621可以设置于变截面段628的面积较大的一端，即：所述变截面段628的一端与所述等截面段627的一端连接，所述变截面段628的另一端与所述清洗通道的出口端621连接，以及所述等截面段627的另一端与所述清洗通道的入口端624连接。通过设置等截面段627与变截面段628，能够在变截面段628处形成稳压腔，从而使经过等截面段627的介质流在变截面段628处进行稳压，以保证出口端621的介质流压力，进而保证介质流对滤网61的冲刷力。可选地，上述等截面段627 设置于进水管626上，变截面段628设置于安装盘625上。
在设置变截面段628与等截面段627时，如果等截面段627的壁面与变截面段628的壁面为棱角过渡(如图19的对比实施例所示)，或者等截面段627与变截面段628即使曲面过渡，但该曲面不与等截面段627的壁面、变截面段628的壁面相切，则介质流在射向滤网61时，会形成两个死角区629。如图19所示，介质流很难流经甚至不会流经死角区629，这样，滤网61位于死角区629的部分则无法被冲刷干净，长期使用，死角区629会聚集大量的线屑，影响风道40的风量。为了解决上述问题，等截面段627的壁面与变截面段628的壁面通过弧形壁面过渡连接，且等截面段627的壁面、变截面段628的壁面均与弧形壁面相切，以使介质流能够经过等截面段627后沿着变截面段628的壁面射向滤网61，进而使介质流能够冲刷至滤网61的每处。在清洗通道的内壁与环形结构的环壁6251a相切时，变截面段628的壁面与环壁6251a相切，通过上述结构，能够使介质流射到滤网61的每处，从而尽可能减小上述死角区629的范围，此时的介质流的流向如图18箭头所示。一实施例中，上述弧形壁面可以为圆弧形壁面，也可以为椭圆弧形壁面。
不论变截面段628与等截面段627如何过渡，变截面段628可以有如下几种设置方式：
第一种方式，变截面段628的过流面在平行于盘面的方向(即图15-16中的X方向)上的尺寸，沿介质流向增大，该尺寸可以呈线性变化，也可以呈非线性变化。在变截面段628的过流面在平行于盘面的方向上的尺寸，沿介质流向呈线性变化时，变截面段628垂直于盘面的方向的截面，可以为等腰梯形结构或直角梯形结构。如图15-16所示，变截面段628包括相 对的第一侧壁6283和第二侧壁6284，第一侧壁6283与第二侧壁6284形成八字形结构，且分别位于介质流相对的两侧。在这种方式中，上述弧形壁面可以为圆弧形壁面，圆弧形壁面在Y方向的投影为圆弧，在保证圆弧形壁面与第一侧壁6283、第二侧壁6284相切的情况下，该圆弧的半径可以尽可能大，以使介质流的流速更稳定，且尽可能缩小死角区629的范围。
第二种方式，变截面段628的过流面在垂直于盘面的方向(如图16-17中的Y方向)上的尺寸，至少部分沿介质流向变小，既可以变截面段628的整个过流面在垂直于盘面的方向上的尺寸均发生变化，也可以仅过流面的其中的一部分在垂直于盘面的方向上的尺寸发生变化。
如图16-17所示，变截面段628仅其中的一部分的过流面在垂直于盘面的方向上的尺寸发生变化，变截面段628包括第一等尺寸部6281和变尺寸部6282。沿介质流向，第一等尺寸部6281的过流面在垂直于盘面的方向上的尺寸(即图16-17中的Y方向)不变，变尺寸部6282的过流面在垂直于盘面的方向上的尺寸变小，且变尺寸部6282较第一等尺寸部6281靠近出口端621，以使出口端621形成扁鸭嘴结构，进而使变截面段628既能够起到稳压的作用，同时能够增加出口端621的介质流压力，增加介质流对滤网61的冲刷力，从而使滤网61被冲刷地更干净。
变尺寸部6282与第一等尺寸部6281通过弧形段过渡，变尺寸部6282、第一等尺寸部6281分别与弧形段相切，以减小介质流的流动阻力，使介质流的流速更顺畅。
在设有变尺寸部6282的情况下，在出口端621处，由于介质流在Y方向的尺寸突然变小，会使介质流在Y方向形成伞状的喷射面，使部分介质流在冲刷力较大时无法与滤网61接触，降低了对滤网61的清洗效果。 为此，变截面段628还包括第二等尺寸部6287，沿介质流向第二等尺寸部6287的过流面在垂直于盘面的方向上的尺寸不变，且变尺寸部6282位于第一等尺寸部6281与第二等尺寸部6287之间，即：所述变尺寸部6282的一端与所述第一等尺寸部6281的一端连接，所述变尺寸部6282的另一端与所述第二等尺寸部6287的一端连接，所述第一等尺寸部6281的另一端与所述清洗通道的入口端624连接，以及所述第二等尺寸部6287的另一端与所述出口端621连接。通过增加第二等尺寸部6287，使介质流在出口端621处的喷射方向更易控制，能够在介质流的冲刷力较大的时候即到达滤网61，从而使滤网61被冲刷的更干净。
变尺寸部6282在垂直于盘面的方向上的尺寸，沿介质流向可以呈线性变化，也可以呈非线性变化。一实施例中，变尺寸部6282可以包括第一底壁6285与第二底壁6286，在变尺寸部6282在垂直于盘面的方向上的尺寸，沿介质流向呈线性变化时，第一底壁6285与第二底壁6286可以均为平面结构。在变尺寸部6282在垂直于盘面的方向上的尺寸，沿介质流向呈非线性变化时，第一底壁6285与第二底壁6286沿垂直于盘面的方向相对设置，第一底壁6285可以为平面结构，第二底壁6286为曲面结构。此时，第一底壁6285可以延伸至第一等尺寸部6281和第二等尺寸部6287，第二底壁6286可以沿其端部的切面所在的延展面延伸至第一等尺寸部6281和第二等尺寸部6287，以形成如图17所示的变截面段628。一实施例中，第二底壁6286还可以继续延伸至等截面段627。可选地，第二底壁6286较第一底壁6285靠近风机20，以使介质流的流动更平稳；一实施例中，也可以第一底壁6285与第二底壁6286均为曲面结构。
第三种方式，变截面段628的过流面在平行于盘面的方向上的尺寸， 沿介质流向增大，同时，变截面段628的过流面在垂直于盘面的方向上的尺寸，至少部分沿介质流向变小。即变截面段628同时具有第一种方式与第二种方式的结构。此时，可以在变尺寸部6282处，变截面段628呈圆锥台结构，或者梯形台结构。
一实施例中，变截面段628也可以采用其它的变截面结构。
实施例四
本实施例提供一种洗衣机及洗衣机的烘干系统，该洗衣机可以为洗衣烘干一体机，如图20所示，该洗衣机的烘干系统包括加热装置10′、风机20′、外筒30′、风道40′以及接口50′，风道40′的一端通过接口50′与外筒30′连通，风道40′的另一端与风机20′连接，风机20′与加热装置10′连接，以将加热装置10′加热的气流通过风机20′经风道40′吹入外筒30′内，实现衣物的烘干。
如图21-24所示，本实施例的烘干系统，还包括设置于风道40′内的过滤装置60′。过滤装置60′包括滤网61′和安装盘62′，滤网61′安装于安装盘62′，一实施例中，如图24所示，安装盘62′包括第一底板621′、第二底板622′和挡水板623′，第一底板621′与第二底板622′相对布置，滤网61′设置于第一底板621′处，挡水板623′垂直于所述安装盘的平面设置于第二底板622′靠近第一底板621′和所述滤网的一侧，挡水板623′与第一底板621′之间形成介质出口624′，即在安装盘62′上形成扁鸭子嘴式的出水口，以增加介质冲出介质出口624′的冲击力，在介质出口624′的出水方向指向滤网61′时，能够将滤网61′上的线屑冲刷地更彻底。
通常，安装盘62′还包括进水管625′，进水管625′与介质出口624′连通，使介质经进水管625′、第一底板621′与第二底板622′的相对空间后由介质出口624′排出。
上述结构，在风道40′内增加过滤装置60′，且过滤装置60′包括滤网61′与安装盘62′，在烘干过程中，当内筒中衣物的线屑被带到风道40′中时，会被滤网61′拦截，防止线屑在风机20′处堆积；且安装盘62′上形成介质出口624′。由图25可以看出，在安装盘62′不设置第一底板621′时，介质经进水管625′向介质出口624′流动，当介质排出介质出口624′时，由于没有第一底板621′的阻挡，一部分介质先向远离滤网61′的表面的方向(如图25中箭头所示的方向)倾斜喷射，然后再流动至滤网61′，另一部分介质由于滤网61′的表面张力效应，沿滤网61′表面流动(如图24中箭头所示的方向)，起到冲刷滤网61′的作用，因此，本实施例中增加第一底板621′，在第一底板621′的阻力作用下，由介质出口624′流出的介质在滤网61′表面张力的作用下，会沿着滤网61′的表面冲刷整个滤网61′，进而将滤网61′上的线屑清洗干净，避免滤网61′堵塞，以保证风机20′、风道40′的畅通，提高烘干系统的热交换效率和烘干效率，缩短烘干时间，降低烘干能耗，以保证衣物烘干的效果；同时防止衣物线屑将风机的扇叶堵塞，影响产品使用寿命。一实施例中，上述介质可以为水，也可以为任意一种清洗剂。
其中，过滤装置60′可以位于风道40′的任一位置处，通常，过滤装置60′安装于风道40′靠近风机20′的一侧，即在图20中，过滤装置60′位于风机20′的下方，以便于使用来自于电磁阀的介质进行冲洗滤网61′。
一般地，通过介质出口624′的介质将滤网61′上的线屑冲刷至风道40′远离风机20′的一端，使这些线屑进入内筒与外筒30′之间的线屑收集器，然后排出洗衣机的外部。
其中，第一底板621′与第二底板622′可以任意一者较另一者靠近风机20′，由于风道40′内的气流流向为风机20′指向风道40′的方向，因此，一实施例中，设置第一底板621′较第二底板622′靠近风机20′，以使由介质出口624′冲出的水流由滤网61′靠近风机20′的一侧向另一侧流动的方向与气流的流向一致，进而使线屑能够随着气流的流向尽快排至线屑收集器。
第一底板621′、第二底板622′以及挡水板623′可以各自为平板结构，也可以是表面为曲面的板状结构。滤网61′可以为平板结构或者凸起结构，在为凸起结构时，滤网61′可以凸向风机20′所在的一侧，滤网61′也可以凸向远离风机20′的一侧。
在滤网61′为平板结构时，滤网61′可以垂直于风道40′的介质流方向。可选地，滤网61′与介质流方向呈一夹角，即滤网61′相对于风道40′的介质流向倾斜设置，以便于冲洗滤网61′时介质能够沿滤网61′向下流动，防止介质聚集在滤网61′上。在滤网61′、第一底板621′均为平板结构时，滤网61′远离第二底板622′的一面，与第一底板621′远离第二底板622′的一面共面，从而使经过介质出口624′的介质能够沿滤网61′的表面流动，到达滤网61′的每个位置，进而使对滤网61′的冲刷更干净；且第一底板621′与滤网61′共面设置，能够减小整个过滤装置60′的体积。一实施例中，滤网61′也可以设置于第一底板621′的其他位置，如滤网61′远离第二底板622′的一面与第一底板621′靠 近第二底板622′的一面共面。
一实施例中，安装盘62′还包括第一侧板626′和第二侧板627′，第一底板621′、第一侧板626′、第二底板622′、第二侧板627′顺次连接，形成清洗通道，清洗通道与介质出口624′连通。沿介质流的流向，清洗通道的过流面积可以不变，也可以逐渐增大，以起到扩压的作用。
在清洗通道的过流面积逐渐增大时，可选地，第一侧板626′与第二侧板627′呈V型结构，V型结构的大端较小端靠近介质出口624′，即进水管625′与清洗通道的一端连通，清洗通道的另一端与介质出口624′连通。通过设置V型结构，由进水管625′至介质出口624′的方向，介质流的过流面积增大，从而起到扩压的作用，使冲刷滤网61′的介质流更稳定，以将滤网61′冲刷的更干净。
此外，安装盘62′还包括安装框架628′，安装框架628′可以为环形结构，如圆环结构、椭圆环结构或者矩形环结构，滤网61′安装于环形结构内。可选地，安装框架628′为开口环结构，即安装框架628′围成形成具有两端的不封闭结构，且具有中空结构，开口环结构可以为开口圆环结构、开口椭圆环结构，或者开口矩形环结构，可选地，开口环结构为开口圆环结构或者开口椭圆环结构，以增加安装框架628′的强度，降低由于介质流的冲击造成滤网61′的变形量。此时，介质出口624′位于开口处，滤网61′安装于安装框架628′内。通过上述结构，既能够保护滤网61′，又能够使介质流通过开口流至滤网61′的表面，减少介质流流动的阻力。一实施例中，滤网61′的边缘沿安装框架628′的周向与安装框架628′连接，以保证滤网61′与安装框架628′的连接可靠性，以及增加滤网61′的抗冲刷强度，避免其受到介质流的冲刷作用力而破裂。
在安装框架628′设有开口时，为了进一步提高安装框架的强度，挡水板623′沿安装框架628′的周向封闭开口，即挡水板623′沿开口环结构的周向的两端分别与开口环结构的两端连接，使挡水板623′与安装框架628′沿上述周向形成封闭的环形结构。可选地，沿开口环结构的轴向，安装框架628′的一侧与挡水板的一侧对齐，安装框架628′的另一侧伸出挡水板623′的另一侧，可以第一底板621′与安装框架628′的另一侧对齐，使介质出口624′位于开口内，这样不增加整个安装盘62′沿上述轴向的尺寸，使过滤装置60′的布置更灵活。也可以，第一底板621′伸出安装框架628′的另一侧，即介质出口624′位于开口外侧。
在挡水板623′沿安装框架628′的周向封闭开口时，挡水板623′可以为平板结构，也可以为弧形结构，当安装框架628′为开口圆环结构或者开口椭圆环结构时，挡水板623′与安装框架628′共同形成圆环结构或者椭圆环结构。
为了使介质流能够充分冲洗到滤网61′的每处，尤其是滤网61′的边缘，第一侧板626′、第二侧板627′分别与开口环结构的两端弧形过渡，即，第一侧板626′、第二侧板627′的内壁形成清洗通道的内壁的一部分，第一侧板626′的内壁、第二侧板627′的内壁与安装框架628′的内壁相切，介质流能够顺着清洗通道与安装框架628′相切的位置冲刷至滤网61′的边缘，以更好地清洗滤网61′的边缘。
上述实施例中，当第一底板621′、第二底板622′均为平板结构时，第一底板621′和第二底板622′可以平行设置，此时，进水管625′的延伸方向可以平行于第一底板621′，也可以与第一底板621′呈非零夹角。
挡水板623′可以为平板结构或者表面为曲面的板状结构，在挡水板 623′为曲面的板状结构时，即沿第一底板621′指向第二底板622′的方向，挡水板623′的投影沿介质流向的两边为曲线。在第二底板622′均为平板结构时，不论挡水板623′采用平板结构还是曲面的板状结构，挡水板623′与第二底板622′可以垂直，即挡水板623′的平行于第一底板621′指向第二底板622′的方向的截面与第二底板622′垂直，该截面也可以与第二底板622′呈一非零夹角。可选地，挡水板623′与第二底板622′垂直设置，以在介质出口624′处增加介质流的冲刷力。
为了防止第一底板621′对流出介质出口624′的介质流的阻挡，挡水板623′与第一底板621′的边缘相对，进而使冲出介质出口624′的介质流能够尽快到达滤网61′，使滤网61′被冲刷的更干净。
此外，介质出口624′能够在洗衣机的洗涤进水、漂洗进水或者烘干过程中，喷射介质流冲洗滤网61′，以使滤网61′经常得到清洗，防止其堵塞。
