用于洗涤设备的送风系统及具有其洗涤设备 技术领域
本发明涉及洗涤设备，具体地涉及用于洗涤设备的送风系统及具有其洗涤设备。
背景技术
洗涤设备，是一种通常利用电能产生的机械力作用来洗涤衣物、床上用品等待洗涤物品的清洁电器。洗涤设备可以方便、快捷、高效地清洁待洗涤物品，从而将人们从繁重的家务劳动中解放出来。目前，洗涤设备主要包括滚筒式洗涤设备、波轮式洗涤设备和拨杆式洗涤设备等多种类型，用于清洗包括但不限于衣物、鞋子、毛巾、地毯、或其它可洗涤物品。其中，滚筒式洗涤设备(例如滚筒式洗衣机、滚筒式烘干机、滚筒式干洗一体机等)具有质量可靠、结构紧凑、洗涤均匀等诸多优点，因此受到越来越多用户的青睐。
滚筒式洗涤设备通常包括壳体、固定在壳体内的外筒、可旋转地固定在外筒内的内筒、和可驱动内筒转动的电机等部件。在壳体的前部通常还设有与壳体形成栓转连接的门体，以便向内筒内放、取待洗涤物品。为了确保门体和外筒之间具有良好的密闭性，现有技术中的滚筒式洗涤设备一般会在外筒的开口处设置具有褶皱结构的窗垫。在使用滚筒式洗涤设备时，部分洗涤水不可避免地会残留在窗垫上，从而滋生细菌、产生异味，极大地降低了用户的使用体验。
为了解决上述的技术问题，现有技术作了大量的研究和尝试。例如，中国发明专利申请CN109306597A公开了一种衣物处理装置的烘干方法、结构及衣物处理装置。在该衣物处理装置的烘干风路上连接至少一路窗垫风路管道，窗垫风路管道的一端伸入窗垫褶皱沟内，以对窗垫褶皱进入烘干。该衣物处理装置将用于烘干窗垫送风系统集成在烘干系统中，以便利用烘干系统产生的热风来烘干窗垫。然而，为了提高烘干效率， 烘干系统产生的热风通常会被控制循环使用，导致送风系统中的湿空气无法及时排出。一旦烘干系统停止工作，湿空气可能会再次冷凝成液态水，从而污染管路和侵蚀部件。因此，该衣物处理装置存在改进的可能性。
相应地，本领域需要一种新的技术方案来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有技术中洗涤设备的送风系统无法将湿空气及时排出的技术问题，本发明提供一种用于洗涤设备的送风系统。该送风系统包括：风机；风道室，在所述风道室内设有彼此间隔的第一通风道和第二通风道；送风管，所述送风管通过所述第一通风道可连通所述风机的排风口，并且定位成可通过运行所述风机给所述洗涤设备的窗垫送风；回风管和排风管，所述回风管通过所述第二通风道可连通所述排风管，所述回风管定位成与所述洗涤设备的外筒的内部相连通，并且所述排风管定位成与外部环境相连通，以便借助运行所述风机迫使所述外筒内的湿空气经由所述回风管和排风管排到所述外部环境中。
本领域技术人员可以理解的是，在本发明用于洗涤设备的送风系统中，包括风机、风道室、送风管、回风管和排风管。在风道室上设置有彼此间隔的第一通风道和第二通风道。送风管通过第一通风道连通风机的排风口，并且定位成可通过运行风机给洗涤设备的窗垫送风。通过上述的设置，可以将风机转动时产生的空气流通过第一通风道和送风管导流到窗垫上，从而加快窗垫上残留水的蒸发速度以去除残留水。同时，回风管通过第二通风道连通排风管，回风管定位成与洗涤设备的外筒的内部相连通，并且排风管定位成与外部环境相连通，使得蒸发后的湿空气可以在由风机转动所引起的空气流的作用下依次沿着回风管、第二通风道和排风管顺利地排到外部环境中。因此，本发明用于洗涤设备的送风系统不仅可以加快窗垫上残留水的蒸发速度，以有效去除残留水，防止其滋生细菌和产生异味，而且可以将湿空气及时排出洗涤设备，防止其冷凝成液态水后污染管路和侵蚀部件。

在上述用于洗涤设备的送风系统的优选技术方案中，所述送风管、 所述回风管和所述排风管为塑料材质的软管。通过将送风管、回风管和排风管均配置成采用塑料材质制成的软管，不仅便于适配洗涤设备内有限且不规则的安装空间，而且可以降低制造成本，此外还便于装配、拆卸和更换。
为了解决现有技术中的上述问题，即为了解决现有技术中洗涤设备的送风系统无法将湿空气及时排出的技术问题，本发明还提供一种洗涤设备。该洗涤设备包括：外筒，在所述外筒的开口处设置有环绕所述开口的窗垫；根据上面任一项所述的用于洗涤设备的送风系统，所述送风系统布置在所述外筒上。通过采用上面任一项所述的用于洗涤设备的送风系统，本发明洗涤设备不仅可以加快窗垫上残留水的蒸发速度，以有效去除残留水，防止其滋生细菌和产生异味，而且可以将湿空气及时排出洗涤设备，防止其冷凝成液体水后污染管路、侵蚀部件。
在上述洗涤设备的优选技术方案中，在所述窗垫的上部或顶部设有可接纳所述送风管的连接管，并且所述连接管延伸进所述开口内。通过上述的设置，可以将送风系统中产生的空气流顺利地导流到窗垫上以吹干残留水。

如图3所示，在一种或多种实施例中，送风管43为采用EPDM(即乙烯、丙烯以及非共轭二烯烃的三元共聚物)加工而成的塑料软管，使得送风管43具有可弯曲的特性，以便于在洗涤设备1的有限的空间内进行装配。替代地，送风管43也可采用PVC、PE或者其它合适的材质加工而成。送风管43具有相对的第一端431和第二端432。第一端431配置成与第一通风道421相连通(参见图6和图7)。第二端432配置成与布置在环形壁12顶部的连接管50相连通(参见图1)。
图9是本发明洗涤设备中连接管的实施例的结构示意图。如图9所 示，在一种或多种实施例中，连接管50具有大致圆柱形的中空的连接管本体51。在连接管本体51的周向侧壁上形成有彼此间隔开的第一限位凸起52和第二限位凸起53。第一限位凸起52可以限定送风管43插入连接管50的位置，并且第二限位凸起53可以限定连接管本体51插入环形壁12中的位置。在一种或多种实施例中，在连接管本体51的周向侧壁上还形成有第一紧固凸起54和第二紧固凸起55。其中，第一紧固凸起54位于靠近第一限位凸起52的位置，使得送风管43和连接管本体51之间可形成牢固的固定连接。第二固定凸起55位于靠近第二限位凸起53的位置，使得连接管本体51和环形壁12之间可形成牢固的固定连接。在一种或多种实施例中，在连接管本体51的末端56还设有导风部57。基于图9所示的方位，导风部57为从连接管本体51的周向侧壁倾斜地朝向连接管本体51的中心线方向延伸的弧形壁571。弧形壁571的设置，可以改变空气流的流向，使沿竖直方向输送进的空气流导流成大致沿水平方向吹向窗垫30，以提升空气流与窗垫30的接触面积，增强送风效果。在一种或多种实施例中，导风部57还包括从弧形壁571垂直向外延伸的分隔筋572。分隔筋572可以扩大空气流的送风范围，进一步增强送风效果。
继续参见图3，在一种或多种实施例中，回风管44为采用EPDM加工而成的塑料软管，使得回风管44具有可弯曲的特性，以便于在洗涤设备1的有限的空间内进行装配。替代地，回风管44也可采用PVC、PE或者其它合适的材质加工而成。回风管44具有相对的第三端441和第四端442。第三端441配置成与第二通风道422相连通(参见图6和图7)。第四端442配置成朝向外筒10的周向壁11，并与周向壁11间隔出预定的距离(参见图1)。
继续参见图3，在一种或多种实施例中，排风管45为采用EPDM加工而成的塑料软管，使得排风管45具有可弯曲的特性，以便于在洗涤设备1的有限的空间内进行装配。替代地，排风管45也可采用PVC、PE或者其它合适的材质加工而成。排风管45具有相对的第五端451和第六端452。第五端451配置成与第二通风道422相连通(参见图6和图7)，使得排风管45通过第二通风道422与回风管44相连通。第六端452配 置成可与外部环境相连通，以便将湿空气及时排出。在一种或多种实施例中，在洗涤设备1的壳体的前部设有与排风管45的第六端452相配的排风孔(图中未示出)。替代地，排风孔的位置也可设置在壳体的其它合适的位置上。另外，当送风系统40工作时，用户可以通过排风孔感知送风系统40的工作状况，以提高用户的使用体验。
如图5所示，在一种或多种实施例中，送风系统40还包括风阀结构46。风阀结构46配置成可同时控制第一通风道421和第二通风道422的开闭。风阀结构46的设置，可以防止送风系统40闲置时洗涤设备1内的洗涤水回流到第一通风道421和第二通风道422内而对风道造成污染。另外，风阀结构46设计成可同时控制第一通风道421和第二通风道422的开闭，还可以精简部件，使送风系统40的结构更加紧凑。
图8是本发明用于洗涤设备的送风系统中风阀结构的实施例的结构示意图。如图8所示，在一种或多种实施例中，风阀结构46包括驱动装置、旋转轴462、第一风阀板463和第二风阀板464等部件。在一种或多种实施例中，驱动装置为风阀电机461。替代地，驱动装置可以是其它可驱动旋转的合适装置。风阀电机461固定在风道室42的风阀电机固定架424上。固定方式包括但不限于于螺纹连接、卡扣连接等。风阀电机461可以是步进式电机、伺服式电机或者其它合适的电机。风阀电机461具有风阀电机轴4611。风阀电机轴4611配置成与旋转轴462形成固定连接。旋转轴462延伸进入第一通风道421和第二通风道422。在一种或多种实施例中，旋转轴462具有远离电机轴4611的固定端4621，并且固定端4621配置成可转动地固定在第一通风道421的远离第二通风道422一侧的侧壁上，使得旋转轴462可以更加稳固地固定在风道室42上。在旋转轴462上形成有并列且彼此间隔开的第一风阀板463和第二风阀板464，以便通过在风阀电机461的带动下，驱动第一风阀板463和第二风阀板464与旋转轴462一起转动，从而同时控制第一通风道421和第二通风道422的开闭。第一风阀板463、第二风阀板464和旋转轴462可采用ABS、PP等合适的树脂材料通过注塑工艺一体成型，以便简化制造工艺，降低制造成本。替代地，第一风阀板463、第二风阀板464也可分别单独加工再固定在旋转轴462上。固定方式包括但不限于螺纹连接、卡扣连接等。 第一风阀板463具有大致长方形的第一风阀板体4631。基于图8所示的方位，在第一风阀板体4631上形成有从第一风阀板体4631垂直向外延伸的第一封闭凸起4632。第一封闭凸起4632具有大致圆形的形状，以便与第一连接件47上的第一通孔471相配。替代地，第一封闭凸起4632也可设置成除圆形以外的其它合适的形状，例如方形、椭圆形等，只要能够与第一通孔471相配以封闭第一通孔471即可。相应地，第二风阀板464具有大致长方形的第二风阀板体4641。基于图8所示的方位，在第二风阀板体4641上形成有从第二风阀板体4641垂直向外延伸的第二封闭凸起4642。第二封闭凸起4642具有大致圆形的形状，以便与第二连接件48上的第二通孔481相配。替代地，第二封闭凸起4642也可设置成除圆形以外的其它合适的形状，例如方形、椭圆形等，只要能够与第二通孔481相配以封闭第二通孔481即可。
在本发明洗涤设备1的送风系统40接收到开启信号后，例如在洗涤设备1的脱水程序结束后，送风系统40中的风机41被控制开始运行。叶轮411在电机的驱动下转动，从而产生空气流。空气流从蜗壳412的排风口414进入风道室42中的第一通风道421内。接着，空气流依次经过送风管43和连接管50，并在连接管50末端56的导风部57的导流作用下，朝向窗垫30吹风。空气流的作用，加快了窗垫30上残留水的蒸发速度，使得残留水转化为气态水。然后，气态水在空气流的带动下，从内筒20的周向侧壁的脱水孔排出内筒20，并从布置在外筒10的周向壁11上的通风孔1111排出外筒10。然后，带有气态水的空气流(即湿空气)从回风管44的第四端442进入回风管44，并依次经过回风管44、第二通风道422和排风管45，最后从排风管45的第六端排出洗涤设备1。因此，通过采用本发明用于洗涤设备1的送风系统40，可以有效去除窗垫30上的残留水，同时将残留水蒸发后的湿空气及时排出洗涤设备1，提升了排湿的效果。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技 术方案都将落入本发明的保护范围之内。
