Description

泵装置及配置有该泵装置的洗涤设备 技术领域
本发明涉及泵装置技术领域，具体涉及一种泵装置及配置有该泵装置的洗涤设备。
背景技术
洗衣机的排水方式有两种，其中一种为上排水，即通过排水泵提升废水高度，使排水过程不会受室内地漏位置的限制。目前，大多数的滚筒洗衣机均采用上排水的形式，方便洗衣机的安装，因此，洗衣机的机体内会设置专用于排水的排水泵。
为了提高衣物的洗净程度，洗衣机中往往还配置有水循环系统，通过将洗衣机盛水筒内的洗涤用水循环泵出并喷洒至衣物上，因此，洗衣机中还往往配置有专用于实现水循环的循环泵。
无论是排水泵还是循环泵，均通过单电机驱动，一个泵仅能实现单一的排水功能或循环水功能，洗衣机要想同时实现排水和水循环功能，则需要同时配置两种泵，这样会占用洗衣机内有限空间来布置两种泵及与其连接的管道，不利于洗衣机的紧凑设计。此外，现有技术中的排水泵和循环泵的水力性能差，扬程低，使得排水过程需要耗费较长的时间。
相应地，本领域需要一种新的泵装置来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有洗衣机的泵装置功能单一、排水量小的问题，本发明的第一方面提供了一种泵装置，该泵装置包括：泵体，其形成有泵腔，所述泵体上设有连通所述泵腔的进水口、第一出水口和第二出水口；叶轮，其设置在所述泵腔内，所述叶轮包括多个叶片；驱动部件，其与所述叶轮连接，用于驱动所述叶轮正反转；其中，所述叶片构造成当所述叶轮沿第一方向旋转时水能够以第一压力从所述第一出水口排出，当所述叶轮沿第二方向旋转时水 能够以第二压力从所述第二出水口排出，所述第一压力大于所述第二压力。
在上述泵装置的优选技术方案中，所述叶轮还包括轮盘，多个所述叶片设置在所述轮盘的一侧，所述叶片相对于所述轮盘的盘面沿所述第一方向倾斜延伸。
在上述泵装置的优选技术方案中，所述叶片沿所述轮盘的径向伸展。
在上述泵装置的优选技术方案中，所述轮盘上开设有多个平衡孔；并且/或者所述轮盘上与所述叶片相背的一侧还设有加强筋。
在上述泵装置的优选技术方案中，所述第一出水口的轴线与所述第二出水口的轴线设置在同一平面上。
在上述泵装置的优选技术方案中，所述第一出水口的轴线与所述第二出水口的轴线垂直。
在上述泵装置的优选技术方案中，所述第一出水口与所述第二出水口之间的泵腔上还设有导流部件，以引导水从所述第一出水口或所述第二出水口排出。
在上述泵装置的优选技术方案中，所述泵装置还包括用于连接所述驱动部件和所述泵体的连接构件；并且/或者所述泵体上还连接有泵座和泵塞。
在上述泵装置的优选技术方案中，所述泵体上还设有连通所述泵腔的残水口。
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，通过将叶轮的叶片倾斜设置，实现了在单一电机驱动下，泵装置能以不同的水压从两个排水口排水，既增加了泵装置的功能，同时实现了排水和循环水的功能，又仅适用单电机即可实现双口排水的效果，节约了硬件成本，提高了用户体验。
本发明的第二方面还提供一种洗涤设备，该洗涤设备配置有上述任一项技术方案中所述的泵装置。
可以理解的是，本发明中的洗涤设备具备上述泵装置的所有技术效果，在此不再赘述。

另外，为了更好地说明本发明，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本发明同样可以实施。在一些实例中，对于本领域技术人员熟知的滚筒洗衣机中的内外筒的运转、洗衣机的减震机构等未作详细描述，以便于凸显本发明的主旨。
基于背景技术指出的现有洗衣机的泵装置功能单一、排水量小的问题，本发明提供了一种泵装置，旨在增加泵装置的功能，从而减少洗衣机中配置的泵的数量，以及缩短泵装置的排水时间。
参照图1-图10，图1为本发明的滚筒洗衣机的结构示意图，其中示出了泵装置与各管路连接的情形；图2为本发明的泵装置的结构示意图；图3为图2的正视示意图；图4为图3中的A-A向剖面示意图；图5为本发明的泵装置去除泵体后的结构示意图；图6为图5的侧视示意图；图7为图5的正视示意图；图8为本发明的轮盘结构示意图；图9为图8的侧视示意图；图10为图2的B-B向剖面示意图。
参照图1，滚筒洗衣机1包括壳体，外筒15设置在壳体内，内筒可旋转地设置在外筒15内，外筒15上方与壳体之间的空间内设置有吊簧13，用于实现内外筒15的减震。洗衣机1的前面板上设有观察窗19，用于观察内筒的内环境。观察窗19的周向设有环形腔，环形腔的内周设有若干喷嘴，环形腔与洗衣机1的循环管16连通，从而使循环管16输送的洗涤用水能通过喷嘴喷淋至内筒中的衣物上。
洗衣机1的左上角设置有用于盛放洗涤剂的洗涤剂盒12，右上角设置有控制面板11，用户通过向控制面板11输入控制命令来控制洗衣机1运行不同的程序，以及通过观察控制面板11显示的信息了解洗衣机1的实时进程。洗衣机1设有进排水系统和循环系统，可以从位于其上部的自来水进水管14向内筒中注水，洗涤用水可以从连接到外筒15底部出水口的进水管18进入泵装置2的泵腔214内，泵装置2同时与排水管17、循环管16和进水管18连通。排水管17的高度为H，循环管16的高度为H1，H＞H1，因此排水管17所需的排水压力要高于循环管16的循环压力。
具体地，参照图2，本发明的泵装置2包括泵体21。泵体21形成有泵腔214，泵体21上设有连通泵腔214的进水口211、第一出 水口212和第二出水口213。第一出水口212与排水管17连接，第二出水口213与循环管16连接，进水口211与进水管18连接。
参照图3和图4，该泵装置2还包括叶轮26，叶轮26设置在泵腔214内，具体来说叶轮26设置在泵体21内的排水腔中。
参照图8，叶轮26包括轮盘261和多个叶片263，本实施例中为4个叶片263。多个叶片263设置在轮盘261的一侧。
参照图2和图5，该泵装置2还包括驱动部件，其与叶轮26连接，用于驱动叶轮26正反转。本实施例中驱动部件为电机22，其通过连接构件固定连接到泵体21上，本实施例中的连接构件为电机座23。
其中，叶片263构造成当叶轮26沿第一方向旋转时水能够以第一压力从第一出水口212排出，当叶轮26沿第二方向旋转时水能够以第二压力从第二出水口213排出，第一压力大于第二压力。
具体地，参照图7和图8，将叶轮26沿顺时针旋转的方向设定为第一方向，将叶轮26沿逆时针旋转的方向设定为第二方向，则叶片263相对于轮盘261的盘面沿顺时针倾斜向上的方向延伸，即叶片263在静止状态下，位于轮盘261表面的叶片263底边缘在轮盘261盘面上的投影位置相对于叶片263顶边缘在轮盘261盘面上投影位置在第一方向上要靠后。
结合图2、图7和图10进行原理阐述。参照图10，叶轮26正转时，即叶轮顺时针旋转时，从进水口211进入泵腔214中的洗涤用水首先沿垂直轮盘261盘面的方向冲击叶轮26，叶轮26顺时针旋转，叶片263顶边缘沿第一方向切割水流并将水体拦截在4个叶片263之间形成的流道中，随着叶轮26的旋转，位于左下、右下、右上的三个流道依次与第一出口212连通，被拦截在这三个流道中的水体依次经第一出口212排出，而被拦截在左上角流道中的部分水体会进入第二排水口213中。第一出水口212的内径远大于第二出水口213的内径，例如第一出水口212的内径为第二出水口213的内径的2～3倍。叶轮26不断地旋转，水体不断地被排出，流道内产生负压，进一步地加速进水，增大进水量，从而使排水量和排水压力增大。在排水过程中，由于绝大部分的水体从第一排水口212中排出，进入第二排水口213的水体极少，而由于叶片的倾斜设置使得排水量倍增甚至增长三倍以上，因此即使有极少量的水 进入循环管，也会被快速排出，相比现有技术中的排水速度有极大的提升。
继续参照图10，叶轮26反转时，即叶轮逆时针旋转时，位于左下、右下、右上的三个流道在叶轮旋转过程中依次与第二出水口213连通，由于叶片263倾斜，使得被拦截的水体会沿着叶片263流道的侧壁，即叶片263表面向着背离轮盘261盘面的方向运动，从而与进水形成一定程度的对冲，使得泵装置2的进水量减小，进而使排水量减少，这样，叶轮26逆时针旋转时输出的水压和水量均低于沿顺时针旋转时输出的水压和水量。
当叶轮26沿顺时针方向旋转时，排水的水压高、水量大，水体会随着叶轮26的旋转同时，但由于排水管17的管径较循环管16的管径粗很多，大量的水在高水压输出状态下被从排水管17快速地排出至机体外，从而加速洗衣机1的排水，提高排水效率。
当叶轮26沿逆时针方向旋转时，排水的水压低、水量小，水虽然会随着叶轮26的旋转同时进入排水管17和循环管16，但由于水压较低，达不到排水管17所需的排水水压，排水管17中的水在达到与循环管16一致的高度后即停止上升，因此水仅会通过第二出水口进入循环管16中，实现水循环。
至此，本发明提供的泵装置2通过改进叶轮26叶片263的形状，实现了在单一电机22驱动下，能以不同的水压从两个排水口排水，增加了泵装置2的功能，同时实现了排水和循环水的功能，节约了硬件成本，同时提高了排水效率，缩短了排水时间，提高了用户体验。
进一步地，叶片263沿轮盘261的径向伸展。参照图8，叶片263的中轴262线与轮盘261的径向方向一致或相近，这样既方便叶轮26的加工，同时还能增大叶片263对水的作用力，从而提高泵的水力性能。
更进一步地，轮盘261上开设有多个平衡孔265，用于平衡轮盘261两侧的压力，同时还能降低叶轮26运转过程中的噪音。
又进一步地，轮盘261上与叶片263相背的一侧还设有加强筋264，以增强叶轮26的强度。
进水口211、第一出水口212和第二出水口213的管接口处设有螺纹，方便与各管路的连接。
第一出水口212的轴线与第二出水口213的轴线设置在同一平面上，有利于水的顺利排出。
进一步地，参照图2和图3，第一出水口212的轴线与第二出水口213的轴线垂直，这样在安装泵体21时，与第二出水口213连接的循环管16可以直上直下地连接到泵体21上，而与排水管17连接的第一出水口212由于是沿水平方向设置的，则可以通过管路引接到洗衣机1的壳体拐角处，从而有利于洗衣机1内各部件的紧凑布置，有利于洗衣机1的紧凑型设计和小型化设计。
需要说明的是，图1中的排水泵并未按照第一出水口水平设置的方式给出。
更进一步地，第一出水口212与第二出水口213之间的泵腔214上还设有导流部件215，以引导水从第一出水口212或第二出水口213排出。参照图10，当叶轮26顺时针转动时，导流部件215的左侧凸沿阻挡水进入第二出水口213，并引导水从第一出水口212排出；当叶轮26逆时针转动时，导流部件215的右侧凸沿阻挡水进入第一出水口212，并引导水从第二出水口213排出。
更进一步地，泵装置2还包括用于连接电机22和泵体21的电机座23。
此外，泵体21上还连接有泵座24和泵塞25。泵座24可以与泵体21制成为一体结构，也可以设置为分体结构，本实施例中的泵座24与泵体21为一体结构。
更进一步地，泵体21上还设有连通泵腔214的残水口216。通过置残水口216，有助于将残留在泵中的残水排除干净，以减少残水对泵体21的腐蚀，从而延长泵装置2的使用寿命。
本实施例中通过可正反转的电机22来驱动叶轮26旋转，电机22通过电机座23连接到泵体21上。电机22实现正反转的方式有多种，比如可以靠一个继电器控制电动机接电容的方法实现电机22正反转，或者通过电子电路控制电机22的电极来实现电机22正反转，又或者可以使用三相电机、无刷直流电机等。
本实施例的第二方面还提供一种滚筒洗衣机1，该洗衣机1配置有前述泵装置2，具备前述泵装置2的所有技术效果，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。
