一种用于洗碗机的连续过滤装置
技术领域
本发明涉及洗碗机领域，特别涉及一种连续过滤装置。
背景技术
目前，家用洗碗机均使用喷水清洗方式，然而这种喷水式洗碗机一方面由于喷水角度问题，难于清洗普通中式餐具，另一方面由于清洗液体在喷射后与餐具的接触时间短，其清洗效果总是差强人意，与此同时，其使用的专用洗碗粉十分昂贵，使用成本较高。鉴于此，喷水式洗碗机一直未能在中国家庭普及。
另有一种水浸式洗碗机由于种种原因一直未能在家庭投入使用，其中一个原因是：洗碗机使用水液体进行浸泡式餐具清洗时，因为餐具表面会附带大量的餐余残渣，餐余残渣随餐具进入待清洗水中，会飘浮在水中。为节省餐具在放入洗碗机前进行预清理的工序，同时减少洗涤剂的使用量，在洗碗机洗涤容器中，设置一个连续过滤装置，可令飘浮的餐余残渣从过滤装置进水口直接排出洗涤容器，从而达到减少洗涤剂使用量，防止水体二次污染餐具。

图5是本发明第五种实施方式的结构示意图。
具体实施方式
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整地描述，以充分地理解本发明的目的、特征和效果。显然，所描述的实施例只是本发明的一部分实施例，而不是全部实施例，基于本发明的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本发明保护的范围。另外，文中所提到的所有联接/连接关系，并非单指构件直接相接，而是指可根据具体实施情况，通过添加或减少联接辅件，来组成更优的联接结构。
图1出示了本发明第一种实施方式的结构， 一种用于洗碗机的连续过滤装置，包括进水池2，其进水口接有进水管，该进水池2内布置有过滤单元；出水池3，连接所述进水池2的出口，该出水池3接有出水管7；水泵12，该水泵12布置在所述进水池2的进水管处或布置在所述出水池3的出水管7处。其中，进水管包括第一排水管5和第二排水管6，第一排水管5连通缸体1内腔的底部，第二排水管6连通缸体1内腔的中上方或中部位置；出水管7的另一端连通缸体1内腔的中部。通过设置两个排水管形成洗碗机缸体的两个吸渣口，位于缸体1内腔的底部的吸渣口吸取含沉淀残渣的洗涤液体，而位于缸体1内腔的中上方的吸渣口吸取含漂浮残渣的洗涤液体，然后流入进水池2，然后通过过滤单元除渣，最后输送回缸体1内腔，使用该装置的洗碗机，形成一个洗涤液体的连续过滤回路。该实施方式中，优选的，进水管还包括第三排水管17，第三排水管17连通缸体1内腔的上方，如此，可增加洗碗机缸体的第三个吸渣口，且第三排水管17的位置与洗涤液体水位相当，即保证洗涤液体上表面的漂浮残渣可从第三排水管17排出。图1所示，第二排水管6是连通缸体1内腔的中上方，而本领域技术人员可可以将其设计为连通缸体1内腔的中部位置。
进一步的，将进水池2设置在缸体1的下方，水泵12布置在出水池3的出水管7处，并且将第二排水管6的最高位低于缸体1内部洗涤液体的水位，即第二排水管6的一端穿过缸体1侧壁连通其内部，由于进水池2位于缸体的下方，那么就可以利用洗涤液体的重力，含有残渣的洗涤液体可经第一排水管5和第二排水管6自由流向进水池2，然后通过过滤单元进行过滤。目前我们将过滤单元设置为两层过滤网，包括粗过滤隔网10和位于其下方的细过滤隔网11，过滤网可以选择不锈钢网，塑料网，沙布等过滤材料。同时，第二排水管6的另一端连接有一水位控制阀9，第一排水管5的另一端也连接到该水位控制阀9的进水口，该水位控制阀9的出水口连接进水池2的进水口，即第一排水管5和第二排水管6可以通过设置在进水池2的水位控制阀9实现控制，当进水池内的水达到设定上限值时，触碰到水位控制阀9的开关，关闭其流通口，使得第一排水管5和第二排水管6停止往进水池2排水，防止进水池2的水溢出以及防止缸体1内部的水过少。
图2出示了本发明第二种实施方式的结构，与第一种实施方式的不同在于：将第二排水管6往上绕过缸体1侧壁后连通其内腔的中上方，第三排水管17也是绕过缸体1侧壁后连通其内腔的上方，可从图2得知，第二排水管6和第三排水管17可以部分共用管路，本领域技术人员可以根据需要设计即可，如此第二排水管6和第三排水管17的最高位均高于缸体4内洗涤液体的水位，无法靠其重力自由流向进水池2，此时，在第二排水管6的另一端连接有一水位控制器15，第一排水管5的另一端也连接到该水位控制器15的进水口，水泵12接有一虹吸辅助管14连接该水位控制器15的水泵进水口，该水位控制器15的出水口连接进水池2的进水口。首先，水泵12启动，将少量水经虹吸辅助管14输送到水位控制器15，此时水位控制器15内部的控制虹吸的阀件打开，使虹吸辅助管14与第二排水管6连通，将第二排水管6的气体排出，达到虹吸条件；其后，启动约5秒后，控制虹吸的阀件关闭，水位控制器15的进水口和出水口相连通，即第二排水管6和第一排水管5的洗涤液体经水位控制器15后流入进水池2；同时，水位控制器15的水泵进水口关闭，即水泵12不再经水位控制器15向第二排水管6进水；随后，水位控制器15进入常规状态，其洗涤液体的除渣过程与第一种实施方式相同。本实施方式中，第三排水管17的原理与第二排水管相同，不再赘述。
图3出示了本发明第三种实施方式的结构，与第一种实施方式的不同在于：进水池2位于所述缸体1的上方，如此进水池2的进水管的最高位高于缸体1内洗涤液体的水位，无法靠其重力自由流向进水池2，此时，将水泵12布置在进水池2的进水管处，可以通过水泵12将含残渣的洗涤液体经第一排水管5、第二排水管6以及第三排水管17输送到进水池2中，另外出水池3过滤后的洗涤液体可以进出水管7直接流入缸体1内。
对第一种、第二种以及第三种实施方式的进一步改进，该用于洗碗机的连续过滤装置还包括一个过滤池，该过滤池的顶部敞口，进水池2和出水池3布置在该过滤池内，进水池2和出水池3之间还布置有水位控制通道4，水位控制通道4也布置在过滤池内，进水池2通过其下部的出水口与该水位控制通道4连通，出水池3通过其上部的进水口与该水位控制通道4连通，进水池2的水位不低于出水池3的水位。首先，洗涤液体流入进水池2，而后经过滤单元除渣，然后从下方的流出槽流向水位控制通道4，其后从水位控制通道4的另一侧溢出流向出水池3，通过将进水池2、出水池3以及水位控制通道4布置在一个过滤池中，使该装置的结构更为紧凑、美观。进一步的，水泵12安装有控制其启闭状态的水位控制球阀13，当水泵12设计位于进水池2上方时，一旦进水池2的水位达到设定上限值时，水位控制球阀13上的球体上浮，进而关闭水泵12，防止进水池的洗涤液体溢出；当水泵12设计位于出水池3时，水泵12优选为潜水泵，一旦出水池3的水位达到设定下限值时，水位控制球阀13上的球体下垂，进而关闭水泵12，防止水泵12损坏。
图4出示了本发明第四种实施方式的结构，与前三种实施方式的不同在于：该用于洗碗机的连续过滤装置还包括一个密闭容器，进水池2和出水池3布置在该密闭容器内，而不是像前三种实施方式那样布置在一个过滤池内。进水池2位于密闭容器的上部，出水池3位于该密闭容器的下部，进水池2包括连通所述进水管的储水室21和连通该储水室21的滤材室22，过滤单元布置在该滤材室22内，此时将水泵12布置在进水池2的进水管处，滤材室22与出水池3相连通。水泵12将含残渣的洗涤液体输送到密闭容器的入口处，再依次流向储水室21、滤材室22和出水池3，经滤材室22的过滤单元过滤除渣，最后流入缸体1的内腔，形成全密封式带压力回路，注意的是，滤材室22的出水口与出水池3相贯通，其中过滤单元包括至少一个滤袋组件23，每个滤袋组件23包括网篮和布置在该网篮内的滤袋，滤袋的外表面紧贴网篮的内壁，储水室21的底壁布置有可嵌入网篮的固定孔，网篮的顶部与储水室21底壁固定连接，采用这种布袋式过滤，可以将密闭容器的顶部设计成可开闭的容器盖，方便清洁或更换滤袋。优选的，密闭容器还安装有压力表16，可实时反映其内部的压力值。
图5出示了本发明第五种实施方式的结构，与第四种实施方式的不同在于：滤材室21和过滤单元的结构的不同，过滤单元包括至少一个滤芯组件24，滤芯组件24的进水口与储水室21连通，滤芯组件24的出水口与出水池3连通，每个滤芯组件24包括中空套筒和填充在该中空套筒内的滤芯，滤芯可以选择陶瓷滤芯、玻纤滤芯活性炭滤芯、纺织纤维绕线滤芯和聚丙烯熔喷滤芯等各种滤芯结构。
对上述五种实施方式的进一步改进，出水管7连通缸体1的一端布置有至少一个回流口8，连续过滤装置通过各回流口8将过滤后的洗涤液体流回缸体1内。进一步，其中一个回流口8位于缸体1内腔的下方，可以在出水管7之间布置微纳米气泡发生器，并通过缸体1内腔下方流出含有微纳米气泡的洗涤液体，设计时，可将回流口8尽量远离第二排水管6的吸水端，可以促使缸体1内部的洗涤液体流动，进一步提高清洁效果。当然还可以根据需要，将回流口8设置在缸体1内腔的中部，又或者在缸体1内腔的中部或下方均设置回流口8。
上面结合附图对本发明的实施方式作了详细说明，但是本发明不限于上述实施方式，在所述技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
