下面参考附图描述根据本申请实施例的用于干衣机的风道壳100。
如图1-图3所示，根据本申请实施例的用于干衣机的风道壳100具有第一腔室110和第二腔室120，其中，第一腔室110用于安装蒸发器200，第二腔室120用于安装冷凝器300。风道壳100包括：本体10和隔板20。
具体而言，本体10的底壁内表面具有排液凹槽11以及导液槽13，隔板20盖封排液凹槽11的槽口以与本体10限定出排液通道12，隔板20实现水汽分离，隔板20上方是内循环风，隔板20下方流经和储存冷凝水。导液槽13与第一腔室110以及排液通道12连通。
如图1-图3所示，干衣机工作产生的湿热空气能够进入风道壳100的第一腔室110和第二腔室120；在与第一腔室110内的蒸发器200进行热交换后，湿热空气中的水冷凝成冷凝水，使湿热空气变为干燥空气；干燥空气与第二腔室120内的冷凝器300进行热交换后，干燥空气变为热空气；热空气能够从风道壳100的风道出口排出，进而进入干衣机的盛衣腔内对衣物进行烘干。其中，第一腔室110内蒸发器200工作产生的冷凝水能够在重力作用下进入导液槽13，进而能够在导液槽13的导流作用下流至排液通道12，以通过排液通道12排出。
在相关技术中，干衣机的底座组件包括基座和两器安装腔体，其中基座设有排水道，两器安装腔体设有与排水道连通的镂空结构，蒸发器工作产生的冷凝水通过镂空结构流至排水 道。上述结构中，两器安装腔体与基座之间存在密封失效的风险，导致冷凝水泄漏或者安装腔内的气流泄漏的风险，不仅影响排水效果，而且不利于安装腔体内气体的热交换效率，不利于两器安装腔体和风道的保温，从而影响干衣机的烘干效率。
而在本申请的实施例中，通过隔板20盖封本体10的底壁上排液凹槽11的槽口，以限定出排液通道12，使排液通道12一体形成于风道壳100内，不存在两器安装腔体和基座之间密封失效的问题，从而有效避免排液通道12内的冷凝水泄漏而影响干衣机的其他部件的使用安全，也避免第一腔室110和第二腔室120内的气体泄漏而影响干衣机的烘干效率。
此外，在本申请的一些实施例中，隔板20为一体成型件，不仅使风道壳100的结构更简单，更易于加工和装配，而且可以减少本体10与隔板20之间的配合缝隙，从而避免排液通道12内的冷凝水通过本体10与隔板20之间的缝隙回流至第一腔室110和第二腔室120内，保证了排水的有效性，避免蒸发器200和冷凝器300被冷凝水浸泡，有利于提高蒸发器200和冷凝器300的换热效率。
根据本申请实施例的用于干衣机的风道壳100，通过本体10的底壁内表面设置排液凹槽11，隔板20与本体10配合限定出排液通道12，使排液通道12一体形成于风道壳100内，有效避免冷凝水泄漏，也避免气体泄漏，有利于提高干衣机的烘干效率，且风道壳100的结构简单，易于加工且防止冷凝水回流。
在一些实施例中，本体10可以为泡沫塑料、泡沫橡胶等发泡件。由此，有利于提高风道壳100的保温效果，同时有利于降低风道壳100的重量。
在一些实施例中，本体10可以包括上壳体和下壳体，其中，下壳体的底壁内表面具有排液凹槽11和导液槽13，隔板20与下壳体限定出排液通道12。为了便于示出风道壳100的排液通道12、导液槽13等内部结构，图1-图3中仅示出了下壳体而未示出上壳体。
申请人研究发现，干衣机长时间运行，虽然有过滤网过滤衣物烘干过程中产生的毛屑或衣物，但小的衣物或毛屑还是无法避免进入风道。进入风道后，小的衣物或毛屑会在蒸发器200的前端面长时间聚集，若不清理会形成大的毛屑或衣物，然后落入导液槽13或隔板20上。落在导液槽13或隔板20上的毛屑或衣物堆积会堵塞导液槽13，导致冷凝水无法顺利流入排液通道12内。并且，导液槽13被堵塞后，冷凝水的水位会升高，浸泡换热器(包括蒸发器200和冷凝器300)导致换热能力降低，影响整机性能，衣物烘干时间加长，耗电增加。
因此，在本申请的一些实施例中，如图1和图2所示，第一腔室110的底壁设有多个导液槽13，多个导液槽13沿气流方向排布，其中，至少一个导液槽13与排液通道12通过过液口14连通，至少两个相邻设置的导液槽13通过连通口15连通。
若其中一个导液槽13被堆积的毛屑或衣物堵塞，该导液槽13内的冷凝水可以通过连通 口15流入相邻的导液槽13内，以通过相邻的导液槽13顺畅进入排液通道12，降低或者避免因导液槽13被堵塞导致换热器热交换能力降低，有利于保证整机的性能，缩短衣物的烘干时间，降低耗电量。
根据本申请实施例的用于干衣机的风道壳100，通过至少两个相邻设置的导液槽13通过连通口15连通，在整机长时间使用后毛屑或杂物堆积堵塞导液槽13后，冷凝水可以通过连通口15流入相邻的导液槽13，以通过相邻的导液槽13顺利排入排液通道12内，有效降低或者避免冷凝水水位升高导致换热器的换热能力降低，有利于提高整机性能，降低衣物烘干时间，降低耗电量。
需要说明的是，在本申请的实施例中，多个导液槽13中，可以其中两个相邻设置的导液槽13通过连通口15连通，以降低导液槽13被堵塞导致换热器热交换能力降低的风险；或者可以如图1和图2所示任意相邻设置的两个导液槽13通过连通口15连通，以使任意一个导液槽13被堵塞时，冷凝水都能够通过连通口15流向相邻的导液槽13以进行排液，大幅度降低导液槽13被堵塞导致换热器热交换能力降低的风险。
此外，继续参照图1和图2所示，任意相邻设置的两个导液槽13通过至少一个连通口15连通。其中，任意相邻设置的两个导液槽13通过多个连通口15连通的实施例中，使相邻两个导液槽13的连通效果好，冷凝水能够从多个位置在两个导液槽13之间流动，有效避免导液槽13被堵塞导致换热器热交换能力降低的风险。
根据本申请的一些实施例，如图1-图3所示，第一腔室110的底壁设有至少一个漏液孔21，漏液孔21连通第一腔室110和排液通道12。冷凝水还可以通过漏液孔21直接由第一腔室110流至排液通道12，以通过排液通道12排出。由此，在导液槽13被堵塞后，冷凝水无法通过导液槽13流至排液通道12时，可以通过漏液孔21排出，以避免冷凝水的水位升高而导致换热器的换热能力降低，有利于提高整机的性能，降低衣物烘干时间。
需要说明的是，在本申请的实施例中，风道壳100可以同时设置连通口15和漏液孔21，也可以仅设置连通口15和漏液孔21中的一种，这都可以降低导液槽13被堵塞导致换热器热交换能力降低的风险。而同时设置连通口15和漏液孔21的实施例中，二者协同作用，避免换热器热交换能力降低的效果更佳。
在一些实施例中，如图1和图2所示，漏液孔21为多个，多个漏液孔21沿气流方向排布，使多个漏液孔21能够从气流方向上更大范围实现冷凝水的排出，冷凝水排出效率更高。需要说明的是，图1-图3中漏液孔21为三个仅用于示例说明的目的，在另一些实施例中，漏液孔21还可以为两个、四个或者更多个，换言之，漏液孔21为两个或两个以上。
根据本申请的一些实施例，如图3所示，漏液孔21设于排液通道12的正上方，如图2所示，漏液孔21位于导液槽13和第一腔室110的侧壁之间。漏液孔21不易被毛屑或衣物 堵塞，且在导液槽13被堵塞之后，冷凝水由导液槽13溢出能够更顺畅地流入漏液孔21，并顺畅地由漏液孔21漏至排液通道12，排液效率更高。
在风道壳100包括本体10和隔板20的实施例中，如图1-图3所示，隔板20可以设有漏液孔21，一方面使漏液孔21直接与排液通道12连通，排液更顺畅，另一方面漏液孔21加工更容易，有利于降低加工工艺难度。
在本申请的一些实施例中，如图1-图3所示，隔板20的一部分形成第一腔室110的底壁，且隔板20的另一部分形成第二腔室120的底壁，隔板20设有至少一个与排液通道12连通的漏液孔21。以使排液通道12的延伸长度更长，有利于避免排液通道12内的冷凝水回流。
此外，继续参照图1-图3所示，漏液孔21形成在第一腔室110的底壁，即漏液孔21形成在隔板20的一部分上，使第一腔室110内的冷凝水能够顺利地通过漏液孔21流至排液通道12内，且排液通道12内的冷凝水由第一腔室110向第二腔室120的方向流动，有利于避免排液通道12内的冷凝水回流。
申请人研究发现，干衣机在运行过程中，第一腔室110和第二腔室120内为负压，而排液通道12与外界连通，使排液通道12内为大气压。运行过程中湿热空气经过蒸发器200将湿热空气中的水汽冷凝成冷凝水后，冷凝水沿排液通道12(如图3中排液通道12内由前向后的箭头所示)流到集水槽中或者排出。而实际过程中因排液通道12和第一腔室110存在内外压力差，冷凝水会顺着回流水方向(如图3中排液通道12内由后向前的箭头所示)吸入第一腔室110，过液口14处冷凝水因局部压差大而沸腾，甚至进入第二腔室120。吸入的冷凝水会影响换热器的换热效率，进而影响整机性能，使烘干时间变长，能耗增加。
因此，在本申请的一些实施例中，如图1和图2所示，多个导液槽13包括至少一个第一导液槽131和至少一个第二导液槽132，第二导液槽132位于第一导液槽131的靠近第二腔室120的一侧，即位于第一导液槽131的下风侧。换言之，第二腔室120沿气流方向位于第一腔室110的下风侧，多个导液槽13包括沿气流方向排布的第一导液槽131和第二导液槽132。再换言之，第二导液槽132为一个或者多个，且第一导液槽131为一个或者多个时，全部第二导液槽132位于全部第一导液槽131的靠近第二腔室120的一侧。例如在图1和图2所示的示例中，风道壳100内气流从前向后流动，第二腔室120位于第一腔室110的后侧，两个第二导液槽132全部位于三个第一导液槽131的后侧。
其中，第一导液槽131通过过液口14与排液通道12连通，且第二导液槽132通过第一导液槽131与排液通道12连通。也就是说，第一导液槽131内的冷凝水可以直接通过过液口14排至排液通道12内，第二导液槽132内的冷凝水需要先流至第一导液槽131，再通道过液口14排至排液通道12内。同样，若由于内外压力差发生冷凝水回流，在压力差的限制 下，回流的冷凝水也只是回流至第一导液槽131内，而不会直接或者间接回流至与第二腔室120距离较近的第二导液槽132内，由此可以避免回流的冷凝水进入第二腔室120，保证了第二腔室120内冷凝器300的热交换效率，解决了整机烘干时间长、能耗高的问题。
例如，在如图1和图2所示的示例中，第一导液槽131的靠近排液通道12的一端通过过液口14与排液通道12连通，第二导液槽132的靠近排液通道12的一端封闭，且第二导液槽132的中部通过第一导液槽131与排液通道12连通。使第二导液槽132与第一导液槽131的连通处与过液口14的间距更大，即使冷凝水通过过液口14回流至第一导液槽131内，也不易进入第二导液槽132，从而避免第二导液槽132内的冷凝水过多而溢出，进而避免冷凝水流至第二腔室120内。
需要说明的是，这里“第二导液槽132的中部通过第一导液槽131与排液通道12连通”是指，第二导液槽132并非通过其靠近排液通道12的一端或者远离排液通道12的一端这两个端部与第一导液槽131连通，而是第二导液槽132的除去两个端部的区域通过第一导液槽131与排液通道12连通。例如，在一些具体实施例中，第二导液槽132的两个端部垂直于气流方向分布，且第二导液槽132具有沿气流方向彼此相对且间隔开的两个侧槽壁，第二导液槽132的侧槽壁设有与第一导液槽131连通的连通口，该连通口位于第二导液槽132的两个端部之间，即位于第二导液槽132的中部，由此，第二导液槽132的中部通过第一导液槽131与排液通道12连通。
在一些实施例中，参照图2所示，第一导液槽131的一端(例如图2中所示的右端)延伸至第一腔室110的侧壁，且第一导液槽131的另一端(例如图2中所示的左端)通过过液口14与排液通道12连通，第二导液槽132的一端(例如图2中所示的右端)延伸至第一腔室110的侧壁，且第二导液槽132的另一端(例如图2中所示的左端)封闭，第二导液槽132的中部通过连通口15与第一导液槽131连通。第一导液槽131的一端和第二导液槽132的一端延伸至第一腔室110的侧壁，使导液槽13能够从更大范围内收集冷凝水，从而使第一腔室110内的冷凝水及时流至排液通道12，避免第一腔室110内冷凝水的水位升高而降低换热器的换热效率。
根据本申请实施例的用于干衣机的风道壳100，通过设置第一导液槽131和第二导液槽132，使发生冷凝水回流时，冷凝水不易进入第二导液槽132和第二腔室120，有效避免第二腔室120内的冷凝器300浸水而降低换热效率，提高了整机的性能，使烘干时间更短、能耗更低。
在包括漏液孔21的实施例中，如图1和图2所示，漏液孔21可以位于排液通道12的靠近第一导液槽131的部分的正上方。换言之，漏液孔21位于多个导液槽13中远离第二腔室120的部分导液槽13的靠近排液通道12的一侧，由此，即使冷凝水通过漏液孔21发生 回流或在漏液孔21处沸腾，回流的冷凝水也不易进入第二导液槽132和第二腔室120，进一步避免第二腔室120内的换热器热交换效率降低，提高了整机性能。
下面结合附图描述第一导液槽131和第二导液槽132的结构。
在一些实施例中，第二导液槽132为一个，第一导液槽131为一个或者多个，第二导液槽132和与其相邻的第一导液槽131通过至少一个第一连通口151连通，以使第二导液槽132内的冷凝水能够通过第一连通口151进入相邻的第一导液槽131，并通过第一导液槽131排至排液通道12内。
在另一些实施例中，如图1和图2所示，第二导液槽132为多个，多个第二导液槽132沿气流方向排布，第一导液槽131为一个或者多个。其中，相邻设置的第一导液槽131和第二导液槽132通过至少一个第一连通口151连通，相邻设置的两个第二导液槽132通过至少一个第二连通口152连通。以使靠近第二腔室120的第二导液槽132内的冷凝水通过第二连通口152进入与之相邻且靠近第一导液槽131的第二导液槽132内，而该第二导液槽132内的冷凝水进一步通过第一连通口151进入相邻的第一导液槽131，并通过第一导液槽131排至排液通道12内。
根据本申请的一些实施例，在气流方向上相邻的两个第二连通口152在第二导液槽132的长度方向错开设置。在回流的冷凝水进入其中一个第二导液槽132后，不易通过第二连通口152流向其他的第二导液槽132，从而降低回流的冷凝水进入第二导液槽132和第二腔室120的风险。以第二导液槽132为三个为例，三个第二导液槽132可以沿前后方向排布且沿左右方向延伸，连通前侧第二导液槽132与中间第二导液槽132的第二连通口152、连通中间第二导液槽132与后侧第二导液槽132的第二连通口152，二者在第二导液槽132的长度方向(即左右方向)错开设置，即二者沿气流方向的投影至少部分不重叠。
根据本申请的一些实施例，如图2所示，靠近排液通道12的第一连通口151和第二连通口152分别与排液通道12的距离在气流方向上逐渐增大，以使靠近排液通道12的第一连通口151和第二连通口152呈阶梯式分布，与排液通道12保持一定距离，即使发生冷凝水回流或者过液口14处冷凝水沸腾，第一导液槽131内的冷凝水也不易通过第一连通口151进入相邻的第二导液槽132，即使通过第一连通口151进入了第二导液槽132，也不易通过第二连通口152进一步进入更靠近第二腔室120的第二导液槽132，有效降低了冷凝水进入第二腔室120的风险，保证了第二腔室120内冷凝器300的热交换效率。
例如，在如图2所示的示例中，第二导液槽132为两个，两个第二导液槽132通过一个第二连通口152连通，其中一个第二导液槽132与相邻的第一导液槽131通过一个第一连通口151连通，该第一连通口151与排液通道12的距离小于第二连通口152与排液通道12的距离。在另一些实施例中，第二导液槽132为三个，后侧第二导液槽132与中间第二导液槽 132通过一个第二连通口152(称为后侧第二连通口152)连通，中间第二导液槽132与前侧第二导液槽132通过一个第二连通口152(称为前侧第二连通口152)连通，前侧第二导液槽132与相邻的第一导液槽131通过一个第一连通口151连通，其中，第一连通口151、前侧第二连通口152和后侧第二连通口152分别与排液通道12的距离依次增大。根据以上描述，第二导液槽132为更多个，第一连通口151和第二连通口152为更多的实施例对本领域技术人员而言是可以理解的。
根据本申请的一些实施例，第一导液槽131可以为一个，或者如图2所示，第一导液槽131可以为多个，多个第一导液槽131沿气流方向排布，相邻设置的两个第一导液槽131通过至少一个第三连通口153连通。由此，在其中一个第一导液槽131被毛屑或者衣物堵塞时，该第一导液槽131内的冷凝水可以通过第三连通口153进入相邻的第一导液槽131，进而排至排液通道12，防止因第一导液槽131被堵塞导致换热器热交换效率降低。
在本申请的一些实施例中，如图1和图2所示，在气流方向上相邻的第三连通口153沿第一导液槽131的长度方向错开设置。错开设置的第三连通口153可以使多个第一导液槽131在更大范围内实现连通，冷凝水流动路径更复杂，降低了在气流方向上相邻的第三连通口153同时被堵塞的风险，排出冷凝水更顺畅。以第一导液槽131为三个为例，三个第一导液槽131可以沿前后方向排布且沿左右方向延伸，连通前侧第一导液槽131与中间第一导液槽131的第三连通口153、连通中间第一导液槽131与后侧第一导液槽131的第三连通口153，二者在第一导液槽131的长度方向(即左右方向)错开设置，即二者沿气流方向的投影至少部分不重叠。
根据本申请的一些实施例，如图1和图2所示，每个导液槽13垂直于气流方向延伸，即导液槽13的长度方向垂直于气流方向。至少一个导液槽13的长度方向的一端通过过液口14与排液通道12连通，以使导液槽13内的冷凝水能够通过过液口14排至排液通道12内。相邻设置的两个导液槽13的宽度方向的一侧通过连通口15连通，以在其中一个导液槽13被毛屑或衣物堵塞时，冷凝水能够通过连通口15进入相邻的导液槽13并排至排液通道12内，降低或者避免对换热器的换热效率的影响。
例如，在多个导液槽13包括第一导液槽131和第二导液槽132的实施例中，如图2所示，第一导液槽131和第二导液槽132分别垂直于气流方向延伸，且第一导液槽131和第二导液槽132的远离排液通道12的一端延伸至风道壳100的侧壁，以使第一导液槽131和第二导液槽132能够更充分收集第一腔室110内的冷凝水，并顺利将收集的冷凝水导流至排液通道12内，提高了排冷凝水的效率。
根据本申请的一些实施例，如图3所示，排液通道12沿气流方向延伸，至少一个导液槽13通过过液口14与排液通道12的进液端(例如图3中所示的前端)连通，例如第一导 液槽131通过过液口14与排液通道12的进液端连通。冷凝水通过过液口14进入排液通道12后，沿气流方向流动以排出至集水槽或者外界，排液通道12的延伸长度更长，有利于解决冷凝水回流的问题。
根据本申请的一些实施例，如图1-图3所示，风道壳100的底壁设有阻挡筋30，阻挡筋30将第一腔室110和第二腔室120隔开。具有一定高度的阻挡筋30可以阻止回流至第一腔室110的冷凝水翻腾通过，冷凝水被彻底阻挡在第一腔室110内，确保第二腔室120内的冷凝器300的热交换效率，解决整机烘干时间长、能耗高的问题。
在本申请的一些实施例中，如图2所示，阻挡筋30的两端分别与风道壳100的彼此相对的两个侧壁相连，例如阻挡筋30的两端分别与图2中所示的左侧壁和右侧壁相连。以使阻挡筋30能够从更大范围内对冷凝水进行阻挡，在导液槽13堵塞或者回流的冷凝水较多导致第一腔室110内垂直于气流方向冷凝水分布范围较大时，阻挡筋30仍能起到良好的阻挡效果，确保第二腔室120内的冷凝器300的热交换效率。
根据本申请的一些实施例，阻挡筋30的顶部低于蒸发器200和/或冷凝器300的靠近风道壳100的底壁的换热管，一方面阻挡筋30能够起到良好的阻挡冷凝水进入第二腔室120的效果，另一方面降低阻挡筋30对气流的阻力，使第一腔室110内的气流能够如图3中箭头所示顺利跨过阻挡筋30，进入第二腔室120，阻挡筋30对蒸发器200和/或冷凝器300的换热管与空气的换热效率基本无影响，保证了热交换效率。
在风道壳100包括本体10和隔板20的实施例中，如图1和图2所示，本体10的底壁内表面具有第一阻挡筋31，隔板20的上表面具有第二阻挡筋32，第一阻挡筋31和第二阻挡筋32相连以构成阻挡筋30，阻挡筋30将第一腔室110和第二腔室120分隔开，阻挡筋30加工更容易。例如，在一些实施例中，第一阻挡筋31可以与本体10的底壁一体加工成型，第二阻挡筋32可以与隔板20一体加工成型，不仅提高阻挡筋30与风道壳100的底壁连接的可靠性和密封性，而且在安装隔板20的同时即可实现阻挡筋30的安装，减少了装配工序。
在本申请的一些实施例中，如图1-图3所示，第二阻挡筋32包括一个或者多个，多个第二阻挡筋32沿其宽度方向间隔布置，即多个第二阻挡筋32沿第一腔室110和第二腔室120的排布方向间隔布置。相邻两个第二阻挡筋32之间形成有一定间隙，以使多个第二阻挡筋32形成多层阻挡屏障。若第一腔室110内的冷凝水的水位高于第二阻挡筋32的高度，冷凝水越过靠近第一腔室110的第一个第二阻挡筋32后，会流至两个第二阻挡筋32之间的间隙，并被第二个第二阻挡筋32阻挡，在阻挡筋30高度一定时能够实现更佳的阻挡冷凝水效果。
根据本申请实施例的干衣机包括根据本申请实施例的用于干衣机的风道壳100。由于根 据本申请实施例的用于干衣机的风道壳100具有上述有益的技术效果，因此，根据本申请实施例的干衣机，通过本体10的底壁内表面设置排液凹槽11，一体件隔板20与本体10配合限定出排液通道12，使排液通道12一体形成于风道壳100内，有效避免冷凝水泄漏，也避免气体泄漏，有利于提高干衣机的烘干效率，且风道壳100的结构简单，易于加工且防止冷凝水回流。
根据本申请实施例的干衣机和风道壳100的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
