Description

滚筒洗衣机及其喷淋系统 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CN102482834B的专利文献中公开的滚筒式洗衣机，其内设置有循环路径，该循环路径的一端通向水槽(外筒)的底端，该循环路径的另一端通向设置在水槽开口边缘的多个喷出口。循环路径能够从水槽的底端将洗涤水供给所述多个喷出口，进而喷进滚筒(内筒)中，对衣物进行循环冲洗。
虽然公开号为CN102482834B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，但是其设置有多个喷出口的水槽结构复杂，生产成本较高。
相应地，本领域需要一种新的滚筒洗衣机来解决上述问题。

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，虽然本发明是以具有扁平结构的喷射孔来进行说明的，但是本发明的喷孔还可以是其他任意结构形式的喷射孔。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。
还需要说明的是，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。
在方案一中：
参照图1，图1是本发明的滚筒洗衣机的实施例一的剖视图。如图1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、密封窗垫5、排水泵6和排水管7。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。排水泵6和排水管7都设置在箱体1内，并且排水泵6的进水口通向外筒2的内底部，排水泵6的出水口与排水管7的一端连接，排水管7的另一端通向外界。排水泵6能够将外筒2内的洗涤水通过排水管7排出。
此外，本领域技术人员能够理解的是，在排水管7的每个部位都低于外筒2的内底端时，本领域技术人员还可以根据需要，省去排水泵6，将排水泵6替换成截止阀。当滚筒洗衣机需要排水时，打开该截止阀，使外筒2中的洗涤水在自身重力的作用下从排水管7自动排出。
继续参阅图1，箱体1的前端(图1中箱体1的左侧)设置有箱体口(图中未标示)，外筒2的前端(图1中外筒2的左侧)设置有外筒口(图中未标示)，内筒3的前端(图1中内筒3的左侧)设置有内筒口(图中未标示)。密封窗垫5的一端与外筒口的边缘密封连接，密封窗垫5的另一端与内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1所示，本发明的滚筒洗衣机还包括喷淋系统，该喷淋系统主要包括循环泵8、出水管9和环形挡水结构，该环形挡水结构设置于外筒2内壁和内筒外壁之间(如图1中所示的环形筋101)，并因此使外筒口的边缘21与环形筋101之间形成具有喷射口102的环形水道10。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，可以将进水管连接到外筒2的任意位置。循环泵8的出水口通过出水管9和环形水道10连通。本发明的 喷淋系统工作时，如图1中箭头所示的，循环泵8将外筒2中的洗涤水泵送给环形水道10，进入环形水道10的洗涤水借助喷射口102被喷射到内筒3中。当内筒3高速运转时，从喷射口102喷出的水流能够快速穿过衣物，并在离心力和重力的作用下进入外筒2中。
参照图2，图2是图1中A部的放大图。如图2所示，在本实施例中，环形筋101设置于外筒2内壁上。这样一来，外筒口的边缘21与环形筋101之间形成即形成了环形水道10，并且，在外筒口的边缘21内筒口之间形成了喷射口102。本领域技术人员能够根据洗衣机的实际应用情况设置环形筋101的具体位置，比如将环形筋101设置于靠近外筒口的边缘21，以减小形成的环形水道10的内径，或者将环形筋101设置于远离外筒口的边缘21，以增大形成的环形水道10的内径。
优选地，喷射口102处设置有导流结构103，该导流结构103用于使进入环形水道10的洗涤水以环形的瀑布水流形式被喷射到内筒3中。作为示例，该导流结构103可以设置于外筒口的边缘21上(图2中所示的即为导流结构103设置于外筒口的边缘21上的情形)，或者改导流结构103还可以设置于密封窗垫5上。换言之，只要能够使该导流结构10实现引导从环形水道10流出的洗涤水的目的的情况下，本领域技术人员可以灵活地设置该导流结构10的位置。
除上述实施例外，图3至图6还示出了本发明的其他实施例。
参照图3和图4，图3是本发明的滚筒洗衣机的实施例二的剖视图；图4是图3中A部的放大图。在该实施例中，与实施例一的区别在于，环形筋10设置于内筒3外壁上。
参照图5和图6，图5是本发明的滚筒洗衣机的实施例三的剖视图；图6是图5中A部的放大图。在该实施例中，与实施例一的区别在于，内筒3外壁和外筒2的内壁上均设置有环形筋10。
需要说明的是，虽然本发明的环形挡水结构是以环形筋为例进行说明的，本领域技术人员可以根据实际设计需要，将环形挡水结构设计为其他形式的结构，例如片状、圆柱状、空心结构等，甚至还可以将环形挡水结构设置为异形环(如使环形挡水结构与外筒口的边缘之间的距离呈变化趋势，即形成的环形水道10具有多个不同的内径)，这些都不脱离本发明的保护范围。
还需要说明的是，本发明的排水泵6和/或循环泵8可以是任意可行的泵，例如、齿轮泵、叶片泵、蠕动泵、离心泵等。
本领域技术人员能够理解的是，在本发明的另一个可行的实施方案中，排水泵6和循环泵8可以被一个泵替代。作为示例一，省去排水泵6，使循环泵8的出水口分别与出水管9和排水管7连通，并且为出水管9配置用于选择性地开启或关闭其的第一截止阀，为排水管7配置用于选择性地开启或关闭其的第二截止阀。当滚筒洗衣机执行喷淋作业时，第一截止阀开启，第二截止阀关闭；当滚筒洗衣机执行排水作业时，第一截止阀关闭，第二截止阀开启。作为示例二，省去排水泵6，并为循环泵8的出水口配置一个三通阀，以便循环泵8的出水口能够借助该三通阀选择性地与出水管9或排水管7连通。此外，本领域技术人员也可以根据需要，使三通阀能够同时阻隔循环泵8与出水管9的连通以及循环泵8与排水管7的连通。
如上所述，本发明通过在外筒2内壁和/或内筒3的外壁上设置环形筋101，从而使得外筒口的边缘21与该环形筋101之间形成环形水道，结构简单，不需要再单独设置循环水路，从而极大地降低了洗衣机的制造成本。并且，本发明形成的环形水道10本身带有喷射口102，不需要再单独设置喷射装置来喷射洗涤水。另外，作为一种优选的示例，本发明的喷射口102处通过设置导流结构103来实现环形瀑布水流的喷射效果，这种喷射效果可以快速地穿过衣物，从而极大地提高了漂洗速率。
另外，本发明还提供了一种滚筒洗衣机，包括洗衣机本体，以及上述中的用于滚筒洗衣机的喷淋系统。关于该滚筒洗衣机的具体实施方式参见上文说明，在此不再赘述。
在方案二中：
如图7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、密封窗垫5、排水泵6和排水管7。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。排水泵6和排水管7都设置在箱体1内，并且排水泵6的进水口通向外筒2的内底部，排水泵6的出水口与排水管7的一端连接，排水管7的另一端通向外界。排水泵6能够将外筒2内的洗涤水通过排水管7排出。
此外，本领域技术人员能够理解的是，在排水管7的每个部位都低于外筒2的内底端时，本领域技术人员还可以根据需要，省去排水泵6，将排水泵6替换成截止阀。当滚筒洗衣机需要排水时，打开该截止阀，使外筒2中的洗涤水在自身重力的作用下从排水管7自动排出。
继续参阅图7，箱体1的前端(图7中箱体1的左侧)设置有箱体口(图中未标示)，外筒2的前端(图7中外筒2的左侧)设置有外筒口(图中未标示)，内筒3的前端(图7中内筒3的左侧)设置有内筒口(图中未标示)。密封窗垫5的一端与外筒口的边缘密封连接，密封窗垫5的另一端与内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7和图8所示，图8是图7中A部的放大图。本发明的滚筒洗衣机还包括喷淋系统，该喷淋系统主要包括循环泵8、出水管9、设置于外筒前端21的环形凹槽22。其中，密封窗垫5具有遮挡部51，遮挡部51与环形凹槽22形成环形水道10(即遮挡部51盖合在环形凹槽22的开口处，从而形成封闭的环形水道10)，在遮挡部51上设置有喷射口511。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，可以将进水管连接到外筒2的任意位置。循环泵8的出水口通过出水管9和环形水道10连通。本发明的喷淋系统工作时，如图7中箭头所示的，循环泵8将外筒2中的洗涤水泵送给环形水道10，进入环形水道10的洗涤水借助喷射口511被喷射到内筒3中。当内筒3高速运转时，从喷射口511喷出的水流能够快速穿过衣物，并在离心力和重力的作用下进入外筒2中。
作为一种示例，本发明的环形凹槽22与出水管9之间可以通过连接结构(如连接软管、连接硬管等)连通，也可以直接连通(即不借助连接结构，直接将出水管9与环形凹槽22连通)，还可以将环形凹槽22与出水管9一体制成。本领域技术人员可以根据实际设计需要灵活地选择合适的连接方式，以使循环泵8能够将洗涤水通过出水管9泵送入环形凹槽22内即可。
继续参照图8，喷射口511为遮挡部51上的窄缝结构。由于环形水道10由遮挡部51和环形凹槽22形成，该环形水道10的喷射口511为遮挡部51上的窄缝结构，因此，本领域技术人员可以根据实际设计需要，在遮挡部51上等间距或者非等间距地设置若干个窄缝结构；或者，还可以设置一个环形的窄缝结构(即沿遮挡部51的圆周开设一个首尾连通的窄缝结构)，这样一来可以实现环形水幕喷淋效果。
作为示例，喷射口511具有导向结构(如将喷射口511设置为斜面状)，该导向结构用于将进入环形水道10的洗涤水倾斜地喷射到内筒3中。除此之外，喷射口511还可以具有喷射组件，该喷射组件用于将进入环形水道10的洗涤水形成均匀的环形水幕后喷射到内筒3中。本领域技术人员容易理解的是，该喷射组件可以根据喷射口511的形状大小进行合理的设计，旨在满足将进入环形水道10的洗涤水形成均匀的环形水幕后喷射到内筒3中。
需要说明的是，本发明的排水泵6和/或循环泵8可以是任意可行的泵，例如、齿轮泵、叶片泵、蠕动泵、离心泵等。
本领域技术人员能够理解的是，在本发明的另一个可行的实施方案中，排水泵6和循环泵8可以被一个泵替代。作为示例一，省去排水泵6，使循环泵8的出水口分别与出水管9和排水管7连通，并且为出水管9配置用于选择性地开启或关闭其的第一截止阀，为排水管7配置用于选择性地开启或关闭其的第二截止阀。当滚筒洗衣机执行喷淋作业时，第一截止阀开启，第二截止阀关闭；当滚筒洗衣机执行排水作业时，第一截止阀关闭，第二截止阀开启。作为示例二，省去排水泵6，并为循环泵8的出水口配置一个三通阀，以便循环泵8的出水口能够借助该三通阀选择性地与出水管9或排水管7连通。此外，本领域技术人员也可以根据需要，使三通阀能够同时阻隔循环泵8与出水管9的连通以及循环泵8与排水管7的连通。
如上所述，本发明利用密封窗垫5的遮挡部51和外筒前端21的环形凹槽22形成环形水道10，并在遮挡部51上直接开设喷射口511，结构简单，对现有滚筒洗衣机的结构改动较小，且不需要再单独设置喷射装置，从而极大地降低了洗衣机的制造成本。另外，作为一种优选的示例，本发明的喷射口511处通过设置导向结构或者喷射组件来实现环 形瀑布水流的喷射效果，这种喷射效果可以快速地穿过衣物，从而极大地提高了漂洗速率。
另外，本发明还提供了一种滚筒洗衣机，包括洗衣机本体，以及上述中的用于滚筒洗衣机的喷淋系统。关于该滚筒洗衣机的具体实施方式参见上文说明，在此不再赘述。
在方案三中：
如图9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、密封窗垫5、排水泵6和排水管7。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。排水泵6和排水管7都设置在箱体1内，并且排水泵6的进水口通向外筒2的内底部，排水泵6的出水口与排水管7的一端连接，排水管7的另一端通向外界。排水泵6能够将外筒2内的洗涤水通过排水管7排出。
此外，本领域技术人员能够理解的是，在排水管7的每个部位都低于外筒2的内底端时，本领域技术人员还可以根据需要，省去排水泵6，将排水泵6替换成截止阀。当滚筒洗衣机需要排水时，打开该截止阀，使外筒2中的洗涤水在自身重力的作用下从排水管7自动排出。
继续参阅图9，箱体1的前端(图9中箱体1的左侧)设置有箱体口(图中未标示)，外筒2的前端(图9中外筒2的左侧)设置有外筒口(图中未标示)，内筒3的前端(图9中内筒3的左侧)设置有内筒口(图中未标示)。密封窗垫5的一端与外筒口的边缘密封连接，密封窗垫5的另一端与内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9至图11所示，其中，图10是图9中A部分的放大图；图11是图9中B部分的放大图。本发明的滚筒洗衣机还包括喷淋系统，该喷淋系统主要包括循环泵8、出水管9、设置于外筒前端21的环形凹槽22以及密封盖板23。密封盖板23与环形凹槽22形成环形水道(即密封盖板23盖合在环形凹槽22的开口处，从而形成封闭的环形水道10)，并在形成的环形水道上设置喷射口101。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，可以将进水管连接到外筒2的任意位置。循环泵8的出水口通过出水管9和环形水道10连通。本发明的喷淋系统工作时，如图9中箭头所示的，循环泵8将外筒2中的洗涤水泵送给环形水道10，进入环形水道10的洗涤水借助喷射口101被喷射到内筒3中。当内筒3高速运转时，从喷射口101喷出的水流能够快速穿过衣物，并在离心力和重力的作用下进入外筒2中。
作为一种示例，本发明的环形凹槽22与出水管9之间可以通过连接结构(如连接软管、连接硬管等)连通，也可以直接连通(即不借助连接结构，直接将出水管9与环形凹槽22连通)，还可以将环形凹槽22与出水管9一体制成。本领域技术人员可以根据实际设计需要灵活地选择合适的连接方式，以使循环泵8能够将洗涤水通过出水管9泵送入环形凹槽22内即可。
继续参照图10和图11，作为一种示例，喷射口101可以是密封盖板23上的窄缝结构，图10和图11中的喷射口101即为在密封盖板23上开设的窄缝结构。作为另一种示例，虽然图中为示出，但是本领域技术人员容易理解的是，喷射口101还可以是环形凹槽22内侧开设的窄缝结构。除此之外，在将密封盖板23盖合到环形凹槽22的开口时，还可以在使密封盖板23与环形凹槽22之间形成一个窄缝结构，将该窄缝结构作为喷射口101。本领域技术人员可以根据实际的设计需要，灵活地设置喷射口101，这些都不脱离本发明的保护范围。并且，由于环形水道10由密封盖板23和环形凹槽22形成，喷射口101为密封盖板23或者环形凹槽22内侧开设的窄缝结构，因此，本领域技术人员可以根据实际设计需要，在密封盖板23或者环形凹槽22的内侧等间距或者非等间距地设置若干个窄缝结构；或者，还可以设置一个环形的窄缝结构(即沿密封盖板23的圆周或者环形凹槽22内侧的圆周开设一个首尾连通的窄缝结构)，这样一来可以实现环形水幕喷淋效果。
作为示例，喷射口101具有导向结构(如将喷射口101设置为斜面状)，该导向结构用于将进入环形水道10的洗涤水倾斜地喷射到内筒3中。除此之外，喷射口101还可以具有喷射组件，该喷射组件用于将进入环形水道10的洗涤水形成均匀的环形水幕后喷射到内筒3中。 本领域技术人员容易理解的是，该喷射组件可以根据喷射口101的形状大小进行合理的设计，旨在满足将进入环形水道10的洗涤水形成均匀的环形水幕后喷射到内筒3中。
需要说明的是，本发明的排水泵6和/或循环泵8可以是任意可行的泵，例如、齿轮泵、叶片泵、蠕动泵、离心泵等。
本领域技术人员能够理解的是，在本发明的另一个可行的实施方案中，排水泵6和循环泵8可以被一个泵替代。作为示例一，省去排水泵6，使循环泵8的出水口分别与出水管9和排水管7连通，并且为出水管9配置用于选择性地开启或关闭其的第一截止阀，为排水管7配置用于选择性地开启或关闭其的第二截止阀。当滚筒洗衣机执行喷淋作业时，第一截止阀开启，第二截止阀关闭；当滚筒洗衣机执行排水作业时，第一截止阀关闭，第二截止阀开启。作为示例二，省去排水泵6，并为循环泵8的出水口配置一个三通阀，以便循环泵8的出水口能够借助该三通阀选择性地与出水管9或排水管7连通。此外，本领域技术人员也可以根据需要，使三通阀能够同时阻隔循环泵8与出水管9的连通以及循环泵8与排水管7的连通。
如上所述，本发明利用密封盖板23和外筒前端21的环形凹槽22形成环形水道10，并在密封盖板23或者环形凹槽23的内侧壁上直接开设喷射口101，结构简单，对现有滚筒洗衣机的结构改动较小，且不需要再单独设置喷射装置，从而极大地降低了洗衣机的制造成本。另外，作为一种优选的示例，本发明的喷射口101处通过设置导向结构或者喷射组件来实现环形瀑布水流的喷射效果，这种喷射效果可以快速地穿过衣物，从而极大地提高了漂洗速率。
另外，本发明还提供了一种滚筒洗衣机，包括洗衣机本体，以及上述中的用于滚筒洗衣机的喷淋系统。关于该滚筒洗衣机的具体实施方式参见上文说明，在此不再赘述。
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。
