Description

一种清洗机 技术领域
本发明涉及一种用于清洗碗碟、果蔬的清洗机。
背景技术
对于台式、柜式洗碗机来说，由于其洗涤空间很大，为达到较好的洗涤效果，一般设计有顶、中、下三个喷臂；工作时，洗涤泵把水通过管道输送到顶、中、下喷臂，水从顶、中喷臂和下喷臂中喷出并冲洗餐具后回落到洗碗机底部的水杯中，洗涤泵把回落的水再次输送到顶、中、下喷臂，完成一个循环。
例如，申请公开号为CN106859563A的中国发明专利申请《节能的洗碗机》(申请号：CN201611232345.5)披露了一种结构，其包括用于容纳餐具并提供清洗空间的腔体、用于喷水清洗餐具的喷淋系统和用于抽水并向喷淋系统供水的泵体；喷淋系统设置于腔体内；泵体的抽水端连通腔体，供水端连通喷淋系统；喷淋系统包括内水管和两套以上喷淋装置，两套以上喷淋装置分别设置于内水管上；泵体的供水端连接有分水装置，该分水装置对应两套以上喷淋装置设置有两个以上出水口，喷淋装置与相应的出水口连通；工作时，分水装置根据指令导通一个以上出水口，使一套以上喷淋装置进行清洗工作。
在上述现有能进行底部喷淋、顶部喷淋的洗碗机中，用于为喷淋系统供水的泵一般采用封闭式结构，即将洗涤泵的蜗壳设于箱体下方，蜗壳内设置有能转动的叶轮，洗涤泵蜗壳的进水口与洗涤腔底部相连通，蜗壳的出水口连接有分水装置，该分水装置将水流分为向底部喷淋臂供水的第一支路和向顶部喷淋臂供水的第二支路。由于顶部喷淋用水与底部喷淋用水的水压均由洗涤泵独立供给，导致分流后每个支路上水流的扬程、流量及冲击力均大幅下降，影响清洗效果。
发明内容
本发明所要解决的技术问题是针对现有技术的现状，提供一种能分别为两路洗涤用水提供动力从而提高扬程及水流量进而提高清洗效果的清洗机。
本发明解决上述技术问题所采用的技术方案为：一种清洗机，包括箱体、第一出水部件、第二出水部件及泵水机构，所述第一出水部件设于箱体下部、用于提供底部喷淋，所述第二出水部件设于箱体上部、用于提供上部喷淋，所述泵水机构用于为第一出水部件、第二出水部件提供汲水动力，所述泵水机构包括能分别为第一出水部件、第二出水 部件独立供水的汲水组件及用于为该汲水组件提供动力的驱动件，所述汲水组件设于箱体中，所述驱动件设于箱体外。
在上述方案中，所述汲水组件包括蜗壳、第一叶轮及第二叶轮，所述蜗壳具有相对独立且分别与箱体流体连通的第一汲水腔、第二汲水腔，所述第一叶轮能转动地设于第一汲水腔中，所述第二叶轮能转动地设于第二汲水腔中，所述驱动件的输出轴与第一叶轮、第二叶轮连接。设置上述结构，便于分别为底部喷淋、上部喷淋提供动力，避免发生供水竞争的问题，从而提高水流扬程。
具体地，所述蜗壳包括上壳体及下壳体，所述上壳体具有用于安装第一叶轮上部的第一容置腔，所述下壳体连接于上壳体的下方，所述下壳体的上部具有用于安装第一叶轮下部的第二容置腔，所述第一容置腔与第二容置腔上下贯通构成所述的第一汲水腔，所述下壳体的侧壁上开有供水进入第二容置腔中的第一进水口，所述第二汲水腔位于下壳体的下部，所述下壳体的侧壁和/或底壁上开有供水进入第二汲水腔中的第二进水口及自第二汲水腔输出的出水口。

优选地，所述上壳体的顶壁和/或侧壁上开有与第一容置腔流体连通的喷孔，所述上壳体能转动地设于下壳体的顶部并构成所述的第一出水部件。
在上述方案中，所述下壳体的中部设置有用于将第二容置腔与第二汲水腔分隔为相对独立的腔体的隔板。使第二容置腔与第二汲水腔相对独立，便于分别通过第一叶轮为下喷淋供水、通过第二叶轮为顶部和/或中部喷淋供水，降低相互之间的流体扰动，减小能力损失，以提高水流扬程、水流量及喷射力度。
优选地，所述第二汲水腔位于隔板下方且大致呈圆盘状，所述第二进水口开设于下壳体的底壁上，所述出水口开设于下壳体的侧壁上且通过导向管道与第二汲水腔切向连接。该结构有利于降低第二汲水腔输出水流的能力损失。
优选地，所述第二容置腔位于隔板上方且竖向延伸，所述第二容置腔的内径小于第二汲水腔的内径且与第一叶片的下部相适配。该结构有利于降低水流在流经第二容置腔时的能力损失。

优选地，所述第一进水口位于敞口上方，且所述第一进水口上连接有倾斜向下延伸至敞口处的吸嘴，所述第二进水口位于敞口旁侧。该结构有利于降低水流的能量损失，提高回水效率及水流扬程。
优选地，所述箱体底部设置有与排水口相连接且用于将排水口关闭或快速排水的阀泵一体结构。以便于将存水快速、充分排出。
优选地，所述沥水区域中设置有用于检测水温和/或检测水浊度的传感器。该结构可为清洗过程提供依据，提高清洗效果。
优选地，所述沥水区域所对应的箱体底壁上设置有用于对水进行加热的加热件。
优选地，所述箱体中设置有用于将箱体底部的水向上为第二出水部件输送的供水管道，该供水管道的下端与所述下壳体的出水口流体连通。

优选地，所述箱体底部还设置有用于控制第一分支管道、第二分支管道流通与否的分水阀，该分水阀的进水口与所述下壳体的出水口相连接，该分水阀的第一出水口与第一分支管道的输入端相连接，该分水阀的第二出水口与第二分支管道的输入端相连接。该结构便于根据需要控制中层与顶层喷淋的使用状态，例如，可将第一分支管道关闭、第二分支管道打开，仅进行顶层喷淋；也可以将第一分支管道打开、第二分支管道关闭，仅进行中层喷淋，以满足更多使用需求。
优选地，所述箱体中部设置有能将其内腔分隔为上下相对独立的上腔体与下腔体的隔板，所述底部喷淋臂位于下腔体的底部，所述中部喷淋臂位于下腔体的中部或上部，所述顶部喷淋臂位于上腔体中。采用这样的结构，便于根据需要对下腔体或上下腔体进行喷淋清洗，以满足消费者的更多需求。
