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嘴来进行说明的，但是本发明的喷嘴还可以是其他任意结构形式的喷嘴。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：
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。
继续参阅图1，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和多个喷嘴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和多个喷嘴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中的洗涤水泵送给多个喷嘴10，多个喷嘴10将洗涤水喷射到内筒3中冲洗衣物。当内筒3高速运转时，从喷嘴10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。
如图1和图2所示，多个喷嘴10绕外桶2的周向等间距地设置在外筒2的前端。或者，本领技术人员也可以根据需要，将多个喷嘴10非等间距地设置在外筒2的前端。
虽然图中并未明确示出，但是在本发明的优选实施方案中，外筒2的前端设置有安装结构，该安装结构与外筒2固定连接，并且该安装结构还与多个喷嘴10固定连接。其中，该安装结构可以是任意可行的结构。作为示例一，该安装结构是卡箍，卡箍上设置有与多个喷嘴10数量相等的卡置位，用于安装、固定喷嘴10。在组装好的状态下，卡箍紧紧地勒在外筒2的前端，并因此将多个喷嘴10固定到外筒2的前端。作为示例二，该安装结构是固定夹，一个喷嘴10对应一个固定夹。具体地，固定夹上设置有一个卡置位，用于安装、固定喷嘴10。在组装好的 状态下，固定夹紧紧地夹住外筒口的边缘，并因此将喷嘴10固定到外筒2的前端。或者，本领域技术人员也可以根据需要，在外筒2的前端设置与喷嘴10数量相等的通孔。将每一个喷嘴10分别插进对应的通孔中，然后再对喷嘴10和通孔进行密封。或者，使喷嘴10与通孔密封连接到一起。
虽然图中并未明确示出，但是在本发明的第一实施例中，出水管9包括环形部分，该环形部分柔性地环绕在外筒2的前端的外侧，以便与所有的喷嘴10连接。在本发明的第二实施例中，出水管9包括多个分支管路(图中未示出)，每个喷嘴10都连接到一个分支管路。并且，每一个分支管路都是柔性的管路，以便使所有的喷嘴10都能够适应外筒2的震动。此外，本领域技术人员还可以根据需要，使远离循环泵8的分支管路的内径大于靠近循环泵8的分支管路的内径，以便使所有喷嘴10喷出的水流大小基本一致。
如图1和图2所示，每一个喷嘴10的出水口都指向内筒3口，以便从喷嘴10喷出的水都能够落入内筒3中，对衣物进行喷淋。优选地，每一个喷嘴10的内部都设置有导流结构101。喷嘴10借助导流结构101将洗涤水倾斜地喷射到内筒3中。或者，本领域技术人员也可以根据需要，将喷嘴10设置成其他任意能够将洗涤水喷射到外筒3中的形式，例如将喷嘴10设置成折弯的形状，从而使喷嘴10的出水口指向内筒口。
如图3所示，为了提高喷淋系统对内筒3中衣物的喷淋效果，每一个喷嘴10都设置成能够喷出扇状水流或瀑布状水流。如图2所示地，每一个喷嘴10的出水端都设置成扁平结构，该扁平结构优选地为喇叭状扁平结构或八字形扁平结构。换句话说，喷嘴10的出水端都设置成其出水端的横截面沿洗涤水流动的方向逐渐变长，同时本领域技术人员可根据需要，选择性地使该横截面的宽度逐渐变小。
此外，在保证内筒3内的衣物能够被喷淋的前提下，本领域技术人员可以根据需要，将喷嘴10的出水端设置成其他任意可行的形状，例如，蜂窝状、圆孔状、三角形状。
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。
综上所述，本发明的喷淋系统在保证内筒3中的衣物得到有效喷淋的情况下，借助安装结构将喷嘴10固定到外筒2的前端，不仅安装方便，而且还使外筒2保持了原有结构，降低了滚筒洗衣机(尤其是外筒2)的生产成本。
在方案二中：
如图4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4，箱体1的前端(图4中箱体1的右侧)设置有箱体口(图中未标示)，外筒2的前端(图4中外筒2的右侧)设置有外筒口(图中未标示)，内筒3的前端(图4中内筒3的右侧)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。
继续参阅图4，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、多个喷嘴10和瀑布发生结构11。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和多个喷嘴10连通。多个喷嘴10和瀑布发生结构11都设置在外筒2的前端附进。本发明的喷淋系统工作时，如图4中箭头所示的，循环泵8将外筒2中的洗涤水泵送给多个喷嘴10，多个喷嘴10将洗涤水喷向瀑布发生结构11之后反射进内筒3中冲洗衣物。当内筒3高速运转时，从喷嘴10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。
如图4至图6所示，多个喷嘴10绕外桶2的周向等间距地设置在外筒2的前端壁上。或者，本领技术人员也可以根据需要，将多个喷嘴10非等间距地设置在外筒2的前端壁上。其中，多个喷嘴10可以绕外桶2的周向布置一圈、两圈或其他任意可行的圈数。进一步，本领域技术人员还可以根据需要，将多个喷嘴10设置在外筒2前端附近的任意位置，例如，将多个喷嘴10设置在门体4的内侧，或者将多个喷嘴12设置在外筒口的边缘处。
虽然图中并未明确示出，但是在本发明的第一实施例中，出水管9包括环形部分，该环形部分柔性地环绕在外筒2的外侧，以便与所有的喷嘴10连接。在本发明的第二实施例中，出水管9包括多个分支管路(图中未示出)，每个喷嘴10都连接到一个分支管路。并且，每一个分支管路都是柔性的管路，以便使所有的喷嘴10都能够适应外筒2的震动。此外，本领域技术人员还可以根据需要，使远离循环泵8的分支管路的内径大于靠近循环泵8的分支管路的内径，以便使所有喷嘴10喷出的水流大小基本一致。
如图5所示，作为示例一，瀑布发生结构11是形成在门体4内侧的瀑布发生槽111。优选地，瀑布发生槽111为多个，以便每一个 喷嘴10都能对应一个瀑布发生槽111。或者本领域技术人员可以根据需要，将瀑布发生槽111设置为环形，使所有的喷嘴10的出水口都指向该环形的瀑布发生槽111，以便从喷嘴10喷出的洗涤水被瀑布发生槽111反射后落入内筒3中，对衣物进行喷淋。
如图6所示，作为示例二，瀑布发生结构11是设置在外筒口边缘处的瀑布发生挡板112。优选地，瀑布发生挡板112为多个，以便每一个喷嘴10都能对应一个瀑布发生挡板112。或者本领域技术人员可以根据需要，将瀑布发生挡板112设置为环形，使所有的喷嘴10的出水口都指向该环形的瀑布发生挡板112，以便从喷嘴10喷出的洗涤水被瀑布发生挡板112反射后落入内筒3中，对衣物进行喷淋。此外，在本发明的另一个可行的实施例中，本领域技术人员可以根据需要，将瀑布发生挡板112设置在密封窗垫5上，或者将瀑布发生挡板112设置在门体4的内侧。
如图7所示，为了提高喷淋系统对内筒3中衣物的喷淋效果，每一个喷嘴10都设置成能够喷出扇状水流或瀑布状水流。将上述示例一中的瀑布发生槽111设置成弧面结构，将上述示例二中的瀑布发生挡板112也设置成弧面结构。
此外，在保证内筒3内的衣物能够被喷淋的前提下，本领域技术人员可以根据需要，将瀑布发生槽111和瀑布发生挡板112设置成其他任意可行的形状，例如，圆弧面结构、椭圆弧面结构、锥形面结构、平面结构等。
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。
综上所述，本发明通过喷嘴10与瀑布发生结构11的配合能够产生扇形/瀑布的水流，喷射到内筒3中喷淋衣物。因此，本发明不仅喷嘴10和/或瀑布发生结构11的安装结构简单，而且还避免了为外筒再单独设计生产模具和制造工艺，降低了外筒的制造成本。
在方案三中：
如图8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8，箱体1的前端(图8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8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8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。
继续参阅图8，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和多个喷淋管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和多个喷淋管10连通。本发明的喷淋系统工作时，如图8中箭头所示的，循环泵8将外筒2中的洗涤水泵送给多个喷淋管10，多个喷淋管10将洗涤水喷射到内筒3中冲洗衣物。当内筒3高速运转时，从喷淋管10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。
如图9至图12所示，多个喷淋管10绕外桶2的周向等间距地设置在外桶2的前端上。或者，本领技术人员也可以根据需要，将多个喷淋管10非等间距地设置在外桶2的前端上。其中，所有的喷淋管10都穿过外桶2的前端，并且都与外桶2的前端密封连接，防止外桶2中的洗涤水泄漏。同时，喷淋管10与外桶2的前端之间的连接还能够对喷淋管10起到定位作用。
对于喷淋管10与外桶2的连接方式，本发明给出了以下实施方式。
第一实施方式，在外筒2的前端上钻与多个喷淋管10数量相等的通孔。喷淋管10穿过通孔后，用密封胶密封喷淋管10和通孔之间的环形缝隙。
第二实施方式，使外筒2和喷淋管10通过卡箍连接。具体地，将卡箍紧紧地勒在外筒2的前端。将喷淋管10固定地连接到卡箍上。喷淋管10可以采用任何可行的连接方式固定到卡箍上，例如绑接、熔接、焊接等。
第三实施方式，使外筒2和喷淋管10通过固定夹连接。具体地，将固定夹紧紧地夹在外筒口的边缘，将喷淋管10固定连接到固定夹上。喷淋管10可以采用任何可行的连接方式固定到固定夹上，例如绑接、熔接、焊接等。
本领域技术人员应当理解的是，喷淋管10与外桶2的连接方式不仅限于上述三种，其还可以是其他任意可行的连接方式。
虽然图中并未明确示出，但是在本发明的第一实施例中，出水管9包括环形部分，该环形部分柔性地环绕在密封窗垫5的外侧，以便与所有的喷淋管10连接。或者本领域技术人员还可以根据需要，设置单独的环形循环管路，使出水管9借助该环形循环管路与多个喷淋管10连通。在本发明的第二实施例中，出水管9包括多个分支管(图中未示出)，每个喷淋管10都连接到一个分支管。并且，每一个分支管都是柔 性的管路，以便使所有的喷淋管10都能够适应密封窗垫5的震动。此外，本领域技术人员还可以根据需要，使远离循环泵8的分支管的内径大于靠近循环泵8的分支管的内径，以便使所有喷淋管10喷出的水流大小基本一致。
如图9至图13所示，在本发明的优选实施方案中，每一个喷淋管10都穿过外筒2的前端壁，并且与外筒2密封连接。并且，每个喷淋管10的末端都设置有瀑布发生结构，从喷淋管10流出的洗涤水经过瀑布发生结构后以瀑布水流(如图14所示)的形式喷淋到内筒3中。
如图11所示，瀑布发生结构包括八字形导水筋101。其中，本领域技术人员可以根据需要，将八字形导水筋101设置成其他任意可行的导水筋，例如扇形导水筋、V形导水筋。
如图13所示，瀑布发生结构还包括设置在八字形导水筋101远离喷淋管10一端的挡水筋102。优选地，每一个喷淋管10配置一个挡水筋102。或者，本领域技术人员还可以根据需要，为所有的喷淋管10配置一个安装到外筒口边缘处的环形的挡水筋。进一步，每一个喷淋管10末端的瀑布发生结构都设置成扁平结构，以便增加瀑布水流发生效果。
此外，在保证内筒3内的衣物能够被喷淋的前提下，本领域技术人员可以根据需要，将喷淋管10的瀑布发生结构设置成其他任意可行的形状，例如，蜂窝状、圆孔状、三角形状。
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。
综上所述，本发明通过将多个喷淋管10设置在外筒2的前端上，并使每一个喷淋管10都能够将洗涤水喷淋到内筒3中，保持了外筒2的原有结构，降低了滚筒洗衣机的生产成本。同时，喷淋管10借助卡箍、固定架固定到外筒2上的安装结构简单易行。
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。
