Description

一种开放式水泵及其应用 技术领域
本发明涉及一种水泵，尤其是一种开放式水泵，以及开水泵的应用。
背景技术
水泵在工作前，水泵和进水管必须灌满水，之后依靠高速旋转的叶轮，使液体在惯性离心力的作用下获得能量从而能提高其内压强，当叶轮快速旋转，叶片促使水很快旋转，随着离心力的作用从叶轮中飞出，水泵内的水被抛出后，叶轮的中心部分形成真空区域，之后水源的水在大气压力(或水压)的作用下进入到进水管内，这样循环不已，就可以实现连续抽水。因为水泵具有结构简单、操作容易、流量易于调节且适用于各种特殊性质物料的输送等优点，广泛应用于各个领域，大至各个工业场所，小至各种家用电器，如洗衣机、洗碗机、空调等。
为了使得水泵加工制造以及安装的便利，目前已出现了一种开放式的水泵，如公开号为EP0807396A2的欧洲专利公开的一种洗碗机，包括用于容纳盘子的洗涤室，支撑在洗涤室底部的喷射臂，泵出洗涤液对喷射臂加压的泵，泵包括叶轮，喷射臂的内表面限定了用于叶轮的壳体，允许洗涤液从壳体到喷射臂的喷嘴进行传递，叶轮包括在较低的边缘处向前弯曲的叶片，叶片的底部具有轴流式叶片部分，叶轮与驱动电机的花键轴接合，在电机无负载下启动后，轴流式叶片部分将流体抬起，从而泵进行正常工作。
然而上述这种开放式水泵，由于水泵的入水口在壳体的下方，来自壳体下方任一方向的水流进入到壳体内被叶轮的叶片抬起后从喷射臂喷淋而出，而由于水流无序的进入到水泵内，叶轮旋转汲水时，容易产生较大的噪音：并且水流刚进入壳体内时，其速度较缓，不利于形成负压，从而影响叶轮的汲水效果。
发明内容
本发明所要解决的第一个技术问题是针对上述现有技术存在的问题，提供一种开放式水泵，便于水泵汲水，并且汲水时噪音较小。
本发明所要解决的第二个技术问题是提供一种应用有上述开放式水泵的水槽式清洗机。
本发明解决上述第一个技术问题所采用的技术方案为：一种开放式水泵，包括上壳体、下壳体和叶轮，所述叶轮包括位于中心的轴和在轴的周面上沿周向均匀分布的多个 沿轴向延伸的叶片，所述叶片在轴向上分为相互连接的上段和下段，所述上壳体中形成有容置叶片上段的上容置空腔，所述下壳体中形成有叶片下段的下容置空腔，其特征在于：所述下壳体的下方，设置有导流环，所述导流环与下壳体之间的水流通道由周边向中心逐渐减小。
该逐渐减小的水流通道的形成方式可以有，在本发明的一个实施例中，所述导流环的上表面呈由周边向中心逐渐向上倾斜的斜面。在本发明的另一个实施例中，所述导流环的上表面呈由周边向中心逐渐向上倾斜的弧形面，所述弧形面呈上凸状或下凹状。上述形状均可以对在入水口处进入的水流进行导向，使其有序的进入到下容置空腔内，由此大大降低了叶轮旋转汲水时的噪音，并且由于入水口的水流通道由外向内逐渐减小，使得水流在进入到下容置空腔前有一个加速的过程，有助于形成负压，获得较好的汲水效果。
为了对水流进行更好的导向和加速，所述下壳体下表面与所述导流环对应的位置设置有相应的环形的导流面，导流面可以和导流环配合。
为便于驱动叶轮转动，所述叶轮的轴穿过所述导流环与电机的输出轴连接，电机转动时带动叶片转动进行汲水。
本发明解决上述第二个技术问题所采用的技术方案为：一种水槽式清洗机，包括形成洗涤空间的箱体，所述箱体包括水槽本体，其特征在于：所述水槽本体的底部至少中央部位形成有沥水区域，所述沥水区域上覆盖有带有沥水孔的沥水板，所述沥水区域内设置有如上所述的开放式水泵，所述导流环固定在所述水槽本体的底部。
在本发明的实施例中，所述上壳体为覆盖在叶轮上的旋转喷臂，所述旋转喷臂包括对合的上盖体和下盖体，所述下盖体的中间形成所述上容置空腔，由此将旋转喷臂作为开放式水泵的出水部件，水流从上容置空腔的侧面流出后进入流道。
为了便于水流从旋转喷臂喷出，所述旋转喷臂的上盖体上开设有出水孔，所述上盖体和下盖体之间形成有与所述上容置空腔连通的流道，所述出水孔与流道的位置对应，由叶轮泵出的水从上容置空腔的侧面流出，通过流道从出水孔喷淋而出。
在本发明的实施例中，所述下壳体为导流支架，导流支架的中心形成所述下容置空腔，所述导流支架的周向上设有多个纵向延伸的安装支脚，使得导流支架悬空设置在水槽本体的底部，由此水泵的入水口位于导流支架的下方和侧面，可以进行及时的补水。
为了便于对水泵进行清洗，所述导流支架顶部中心外周具有上台阶面，所述上壳体搁置于所述上台阶面上，清洗水泵时只需将上壳体从导流支架上拿下取出叶轮即可。
与现有技术相比，本发明的优点在于：在开放式水泵的入水口位置设置导流环，对在该入水口处进入的水流进行导向，使其有序的进入到下容置空腔内，由此大大降低了叶轮旋转汲水时的噪音，并且由于入水口的水流通道由外向内逐渐减小，使得水流在进入到下容置空腔前有一个加速的过程，有助于形成负压，获得较好的汲水效果；在水泵 的下壳体的下表面设置与导流环对应的导流面，可进一步加强水流进行导向和加速；采用了本发明的开放式水泵的水槽式清洗机，具有较好的汲水效果，使得旋转喷臂对水槽本体内的碗碟、蔬果等洗涤时喷淋效果好，清洗的较为干净。

具体实施方式

水槽本体1的底板11至少在中央部位下凹，在底板11下凹部分的上方，间隔地覆盖有与下凹部分形状相同的沥水板3，沥水板3上开设有多个用于沥水的沥水孔31，沥水板3和底板11下凹部分之问间隔的空间形成沥水区域32，沥水板3与底板11的其他部分齐平。水槽本体1外侧，底板11的下方安装有电机4，电机4的输出轴41伸入到水槽本体1内后，位于底板11上方的沥水区域32内。
沥水区域32内设置有开放式的水泵5，水泵5包括叶轮51，叶轮51包括位于中心的中空的轴511以及多个设置在轴511周面上的叶片512，叶片512在轴511的周面上均匀分布并且沿轴向延伸，并且叶片512在轴向上分为相互连接的上段5121和下段5122，轴511的下端与电机4的输出轴41连接，由此电机4转动时可带动叶轮51转动。
叶轮51外设置有导流支架52，导流支架52周向上设有多个安装支脚521，可通过螺钉等将安装支脚521与底板11或电机4固定，安装支脚521纵向延伸，使得导流支架52的底面与沥水区域32的底面之间具有间隔形成悬空设置在水槽本体1底部的状态，以供沥水区域32内的水流通过。叶片512的下段5122位于导流支架52中心形成的下容置空腔522内，上段5121露出于导流支架52，由此，导流支架52形成开放式水泵5的下壳体。导流支架52中心下容置空腔522的外周具有下台阶面524，与沥水板3的下 表面抵接，沥水板3搁置于下台阶面524上。
导流支架52的顶部覆盖有旋转喷臂53，旋转喷臂53位于沥水板3上方，其中间底部形成有上容置空腔531，以容纳叶片512的上段5121，由此，旋转喷臂53形成开放式水泵5的上壳体，水泵5用于将沥水区域32内的水泵出，通过旋转喷臂53对待清洗对象(上文所述的碗碟、蔬菜、水果等)进行冲洗。
导流支架52的下方敞开，水流可以从导流支架52的下方和侧面进入到叶轮51，即开放式水泵5的入水口位于导流支架52的下方和侧面，旋转喷臂53的相对上容置空腔531的顶面封闭，水流从上容置空腔531的侧面流出，即开放式水泵5的出水口位于旋转喷臂53内上容置空腔531的侧面。
旋转喷臂53包括对合的上盖体532和下盖体533，两者之间形成与上容置空腔531连通的流道，上容置空腔531位于旋转喷臂53的中间，而流道位于上容置空腔531的两侧。导流支架52顶部中心外周、位于下台阶面524上方的位置处还设有上台阶面525，与旋转喷臂53的下表面抵接，旋转喷臂53搁置在上台阶面525上。上盖体532上表面开设有多个出水孔5321，出水孔5321位于流道的上方，与流道相对应，由叶轮51泵出的水通过上容置空腔531进入到流道，进而从出水孔5321喷出，对待清洗对象进行冲洗。
底板11上位于导流支架52的下方，即开放式水泵5的入水口设有导流环54，导流环54的位置与导流支架52对应，并且电机4的输出轴41从导流环54中心穿过与叶轮51的轴511连接，导流环54的上表面由周边向中心逐渐向上倾斜，由此使得和导流支架52下表面之间的距离由周边向中心逐渐减小，即使得该处的水流通道由周边向中心逐渐减小，导流环54可对在该入水口处进入的水流进行导向，使其有序的进入到下容置空腔522内，由此大大降低了叶轮51旋转汲水时的噪音，并且由于入水口的水流通道由周边向中心逐渐减小，使得水流在进入到下容置空腔522前有一个加速的过程，有助于形成负压，获得较好的汲水效果。
在本实施例中，参见图4-1，导流环54的上表面呈由周边向中心逐渐向上倾斜的斜面541。
导流环54还可以设计成其他结构，如图4-2所示的另一个实施例中，导流环54的上表面呈由周边向中心逐渐向上倾斜的弧形面542，该弧形面呈上凸状；如图4-3所示的又一个实施例中，该弧形面呈下凹状。
