Description

滚筒洗衣机及其密封窗垫和喷淋系统 技术领域
本发明属于家用电器领域，具体提供一种滚筒洗衣机及其密封窗垫和喷淋系统。
背景技术
现有滚筒洗衣机发源于欧洲，其由外至内主要包括箱体、外筒和内筒。滚筒洗衣机的工作方式与棒锤击打衣物原理类似。工作时，内筒在驱动电机的带动下转动。随着内筒的转动，衣物在滚筒中不断地被提升摔下，再提升再摔下，做重复运动。在洗衣粉和水的共同作用下，衣物被洗涤干净。
为了提高水流冲洗和漂洗衣物的效果，有的滚筒洗衣机还设置有循环喷淋装置。如公开号为CN204982446U的专利文献中公开的滚筒式洗衣机，由外至内依次包括机体、滚筒和盛水桶。其中，盛水桶上设有盛水桶框架，盛水桶框架上设有用于向滚筒内喷射水流的喷淋孔和用于引导喷射水流周向扩散的导流机构。从喷淋孔出来的水柱喷向导流机构后，宽度被扩大，水柱被调整为扇形喷向内筒。
虽然公开号为CN204982446U的专利文献中公开的滚筒式洗衣机对衣物的清洁能力较强，但是其喷淋孔和导流结构的结构复杂，生产成本较高。
相应地，本领域需要一种新的滚筒洗衣机及其喷淋系统来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有具有循环喷淋功能的滚筒洗衣机的喷淋装置结构复杂、生产成本较高的问题，本发明提供了一种滚筒洗衣机的密封窗垫，所述滚筒洗衣机包括由外至内依次设置的箱体、外筒和内筒，所述密封窗垫设置在所述箱体和所述外筒之间；所述密封窗垫包括：

在上述密封窗垫的优选技术方案中，所述本体包括环形的第一本体和环形的第二本体，所述第一本体和所述第二本体一体制成，所述第一本体轴向上的一端与所述箱体的箱体口的边缘相连接，所述第一本体轴向上的另一端与所述外筒的外筒口的边缘相连接，所述环形腔形成在所述第二本体上。
在上述密封窗垫的优选技术方案中，所述第一本体靠近所述外筒的一端设置有多个卡接结构，所述第一本体通过所述卡接结构与所述外筒口的边缘卡接到一起。
在上述密封窗垫的优选技术方案中，所述第二本体设置在所述第一本体靠近所述外筒的一端上。
在上述密封窗垫的优选技术方案中，所述第一本体和所述第二本体采用不同的材料制成。
在上述密封窗垫的优选技术方案中，所述第一本体采用具有弹性的橡胶材料制成，所述第二本体采用塑料制成。
在上述密封窗垫的优选技术方案中，所述密封窗垫还包括设置在所述本体上的挡水结构，所述挡水结构邻近所述喷水通道的出水口设置，并且所述挡水结构设置成能够将每一个所述喷水通道喷出的洗涤水打散并反射进所述内筒中。
在上述密封窗垫的优选技术方案中，所述挡水结构是呈环状的挡水环；或者，所述挡水结构包括多个呈弧状的挡水板，每一个所述挡水板对应一个或多个喷水通道。
此外，本发明还提供了一种滚筒洗衣机的喷淋系统，所述喷淋系统包括循环泵和上述优选技术方案中任一项所述的密封窗垫，所述循环泵的进水口通向所述外筒内，所述循环泵的出水口与所述密封窗垫的进水通道连通。
另外，本发明还提供了一种滚筒洗衣机，所述滚筒洗衣机包括上述密封窗垫的优选技术方案中任一项所述的密封窗垫。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过在密封窗垫的本体上设置有环形腔、与环形腔连通的进水通道以及与环形腔连通的喷水通道，使得循环泵能够将外筒中的洗涤水通过进水通道泵送到环形腔中，进而通过喷水通道将洗涤水喷射进内筒中，对内筒中的衣物进行喷淋。因此，本发明的喷淋系统/滚筒洗衣机在能够喷淋内筒中衣物的同时，还简化了喷淋装置的结构，尤其是本发明的密封窗垫可以采用一体制成的方式形成所述环形腔、所述进水通道和所述喷水通道。基于密封窗垫的上述结构和制作工艺，本发明还降低了喷淋系统的生产制造成本。
进一步，本发明的密封窗垫的本体上还设置有挡水结构，该挡水结构能够将每一个喷水通道喷出的洗涤水打散并反射进内筒中，使洗涤水均匀地喷淋到内筒中的衣物上，优化了洗衣机的洗涤效果。

具体实施方式
本领域技术人员应当理解的是，本节实施方式仅仅用于解释本发明的技术原理，并非用于限制本发明的保护范围。例如，虽然附图中的各部件之间是按一定比例关系绘制的，但是这种比例关系并非一成不变，本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。
需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
如图1和图2所示，本发明的滚筒洗衣机主要包括箱体1、外筒2、内筒3、门体4和密封窗垫5。其中，外筒2固定地设置在箱体1内，内筒3可转动地设置在外筒2中，密封窗垫5设置在箱体1和外筒2之间。
如图2所示，箱体1的前端(图2中箱体1的上侧)设置有箱体口(图中未标示)，外筒2的前端(图2中外筒2的上侧)设置有外筒口(图中未标示)，内筒3的前端(图2中内筒3的上侧)设置有内筒口(图中未标示)。密封窗垫5的一端与箱体口的边缘密封连接，密封窗垫5的另一端与外筒口的边缘密封连接。门体4枢转地设置在箱体1上，并且门体4关闭时能够封闭所述箱体口，防止外筒2中的洗涤水从箱体口溢出。
如图3和图4所示，本发明的密封窗垫5包括本体，该本体包括环形的第一本体51和环形的第二本体52，并且第一本体51和第二本体52一体制成。其中，图4中第一本体51的上端与箱体1的箱体口的边缘固定连接，图4中第一本体51的下端与外筒2的外筒口的边缘固定连接。第二本体52设置在第一本体51的下端，或者本领域技术人员也可以根据实际需要，将第二本体52设置在第一本体51的上端，或者将第二本体52设置在第一本体51上下两端之间的任意位置。
如图3和图5所示，第一本体51的上端采用卡接的方式与箱体1固定连接，或者本领域技术人员也可以根据实际需要，使第一本体51与箱体1之间采用任意可行的方式连接到一起，例如压接、熔接、扣接等连接方式。第一本体51的下端同样采用卡接的方式与外筒2固定连接到一起。具体地，第一本体51的下端设置有卡接结构，第一本体51的下端通过该卡接结构与外筒口的边缘卡接到一起。更具体地，第一本体51的下端设置有多个第一凹槽511，外筒口的边缘设置有多个凸起21，通过使凸起21卡进第一凹槽511中来实现第一本体51和外筒2之间的 卡接。优选地第一凹槽511和凸起21均呈环形，并且与所述外筒2同轴或接近于同轴设置。
此外，本领域技术人员也可以根据需要，将第一凹槽511替换成凸起结构，将凸起21替换成与所述凸起结构相匹配的凹槽。进一步，本领域技术人员还可以根据需要，采用其他任意可行的连接方式将第一本体51和外筒2固定到一起，例如扣接、熔接、压接等连接方式。
如图3和图4所示，本发明的密封窗垫5还包括形成在第二本体52上的环形腔521、进水通道(图中未示出)、多个喷水通道522和挡水结构523。其中，进水通道和多个喷水通道522分别设置在图4中第二本体52左右方向上的两侧，并且进水通道和多个喷水通道522分别与环形腔521连通。多个喷水通道522中的每一个的出水口都指向内筒3。本领域技术人员能够理解的是，在能够将进水通道和喷水通道522连通的前提下，环形腔521不仅限于O形的环形腔，其还可以是C形的环形腔。
继续参阅图3和图4，挡水结构523设置在图4中第二本体52的左侧，使得每一个喷水通道522的出水口都指向挡水结构523，以便从每一个喷水通道522中喷出的洗涤水都能够喷射到挡水结构523上，被挡水结构523打散(如图1中所示的被喷淋的洗涤水)并反射进内筒3中，从而均匀地喷淋内筒3中的衣物。本领域技术人员能够理解的是，挡水结构523除了被设置在第二本体52上之外，还可以被设置在第一本体51上。
虽然图中并未示出，但是基于挡水结构523能够将每一个喷水通道522喷出的洗涤水打散并反射进内筒3中的情况，本领域技术人员可以将挡水结构523设置成任意可行的形式。作为示例一，挡水结构523是呈环状的挡水环，该挡水环能够将每一个喷水通道522喷出的洗涤水都反射进内筒3中。作为示例二，挡水结构523包括多个呈弧状的挡水板，并且每一个挡水板对应一个喷水通道522。或者，本领域人员也可以根据需要，使一个挡水板对应多个喷水通道522。需要说明的是弧状的挡水板不仅包括具有一定弧度的板状结构还包括平面的板状结构。
此外，在本发明另一个可行的实施方案中，本领域技术人员也可以根据需要，省去挡水结构523，使喷水通道522喷出的洗涤水直接喷向内筒3中。进一步，本领域技术人员还可以根据需要，将喷水通道 522的出水口设置成能够喷出瀑布状的水流，例如将喷水通道522的出水口设置成扁平状或扁平的喇叭口状。
如图3和图4所示，为了提高密封窗垫5和外筒2之间的连接强度，第二本体52上也设置有卡接结构，如图4中所示的与外筒4上的凸起相匹配的凹槽。或者，本领域技术人员也可以根据实际需要，仅在第一本体51或第二本体52上设置与外筒4上的被卡接结构相匹配的卡接结构。
在本发明的优选实施方案中，第一本体51和第二本体52采用不同的材料制成。具体地，第一本体51采用具有弹性的橡胶材料制成，第二本体52采用塑料制成。生产时，先通过塑料成型模具将第二本体52制作成型。然后将第二本体52放入橡胶成型模具中，再通过橡胶成型模具将第一本体51制作成型。成型之后的第一本体51如图4中所示的将第二本体52包裹在一起，并因此使得第一本体51和第二本体52被一体制成。或者，本领域技术人员也可以根据需要，采用其他任意可行的材料和生产工艺将第一本体51和第二本体52一体制作成型，例如采用双色成型工艺将第一本体51和第二本体52一体制作成型。此外，本领域技术人员也可以根据需要，使第一本体51和第二本体52采用相同的材料制成。
本领域技术人员能够理解的是，进水通道和喷水通道522可以是在第二本体52制作时直接形成在第二本体52上，也可以是在第二本体52制作完成之后，通过加工的方式形成在第二本体52上。
本领域技术人员还能够理解的是，第二本体52之所以采用具有弹性的橡胶材料制成，是为了支撑图4中第一本体51的下端，使第一本体51和第二本体52被牢固地卡接到外筒2上，防止密封窗垫5从外筒2上脱落。
进一步，虽然图中并未示出，但是本发明的滚筒洗衣机还包括喷淋系统，该喷淋系统包括上述的密封窗垫5和循环泵。其中，循环泵8优选地设置在箱体1内且与箱体1固定连接。或者本领域技术人员也可以根据需要，使循环泵8与外筒1固定连接。循环泵8的进水口通向外筒2的内部，优选地，循环泵8的进水口通过进水管(图中未标示)与外筒2的底端连接。或者本领域技术人员也可以根据需要，在保证该进水管位于外筒2内液面以下的情况下，将进水管连接到外筒2的任意 位置。此外，本领域技术人员还可以根据需要，省去进水管的设置，使循环泵8的进水口直接与外筒2连通。循环泵8的出水口通过出水管与密封窗垫5上的进水通道连通。或者，本领域技术人员也可以根据需要，省去出水管，使循环泵8的出水口与进水通道直接连通。
综上所述，本发明设置有环形腔521、进水通道和喷水通道522的密封窗垫5不仅结构简单，而且制作工艺也比较简单，并且本发明的滚筒洗衣机还不需要安装其他额外的喷淋装置就能够喷淋内筒3中的衣物，降低了滚筒洗衣机的生产成本。
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。
