Description

净水*** 技术领域
本发明涉及水净化技术领域，尤其涉及一种净水***。
 背景技术
在净水***中，滤膜件内的浓水侧的浓水经过换向阀分成两路，一路作为废水而排出，另一路与自来水混合后重新供入滤膜件以重新参与制备直饮水。
现有技术中通常采用如下两种方式使自来水与浓水进行混合。
第一种：利用三通连接自来水管与回水管路，来自自来水管的自来水与来自回水管路的浓水进入到三通，然后从三通的出水端口流出而供入滤膜件。
第二种：自来水管以及回水管路均连接至水箱，来自自来水管的自来水与来自回水管路的浓水首先进入到水箱中，而后供入滤膜件件。
现有技术中的上述两种混合方式存在如下缺陷：
1、由于三通具有较大的节流作用，这导致三通与换向阀之间的管路存在较大的节流压力，该节流压力严重影响换向阀对浓水流量的调控，例如，在换向阀的通流截面不变的情况下，节流压力使得从换向阀流出的用于重新参与制水的浓水的流量和流速均较小，进而导致滤膜件的浓水侧的水的流量和流速较小。另外，进入三通的自来水与浓水来不及混合便供入滤膜件，进而导致混合不均匀。
2、进入水箱中的自来水与浓水的流动性均不强，导致两者混合效果较差。

为了保持本发明实施例的以下说明清楚且简明，本发明省略了已知功能和已知部件的详细说明。
如图1和图2所示，本发明公开了一种净水***，该净水***包括：滤膜件20、换向阀50、混水装置10、水泵30、第一回水管路41、第二回水管路42、第三回水管路44、出水管路、自来水管43、流量阀61、电磁开关阀62、第一流量计81、第二流量计82、过滤器70以及杀菌器92。
滤膜件20被其内的膜片分成净水侧21和浓水侧22，出水管路连接至净水侧21，该出水管路分成两路，即，第一出水管路441和第二出水管路442，第一出水管路441延伸至如水龙头等直饮水出水端口，第二出水管路442伸入至用于存储直饮水的直饮水储水箱91中。
换向阀50借由第一回水管路41与滤膜件20的浓水侧22的出口连通，该换向阀50具有废水口和回水口，从浓水侧22流出的浓水借由第一回水管路41而经过换向阀50，换向阀50使得该浓水一部分经过废水口作为废水而排出，另一部分经过回水口而与从自来水管43流出的自来水混合以重新通过浓水侧22的进口进入滤膜件20而参与制备直饮水。
如图1至图3所示，混水装置10包括柱状壳体11、自来水进液口121、浓水进液口122以及出液口123，该柱状壳体11内形成有柱状腔室，自来水管43与自来水进液口121连通，换向阀50的回水口借由第二回水管路42与浓水进液口122连通，出液口123借由第三回水管路44与浓水侧22的进口连通。如此，来自自来水管43且经过自来水进液口121进入到柱状腔室中的自来水与来自第二回水管路42且经过浓水进液口122进入到柱状腔室中的浓水在柱状腔室内混合，而后从混水装置10的出液口123流出而进入到滤膜件20的浓水侧22参与制备直饮水。
在本发明中，混水装置10的出液口123形成于柱状壳体11的头部的端面，而混水装置10的自来水进液口121和浓水进液口122具有如下特点：
自来水进液口121与浓水进液口122形成有靠近柱状壳体11内部的壳壁上；自来水进液口121与浓水进液口122均与柱状腔室相切且连通，且自来水进液口121与浓水进液口122位于同一平面；自来水进液口121与浓水进液口122的朝向相反。
基于上述特点可知：自来水经过自来水进液口121的导向作用以及浓水经过自浓水进液口122的导向作用均以切线方向进入到柱状腔室内并作圆周运动，以该方式进入到柱状腔室内会极大的降低节流压力，尤其是混水装置10与换向阀50的回水口之间的节流压力，即，第二回水管路42内的压力，这是使得浓水从换向阀50的回水口更顺畅的流出，有利于换向阀50对浓水流量的控制，能够有效提高流经滤膜件20的浓水侧22的浓水的流量和流速，提高了直饮水的品质。
另外，水进入到柱状腔室内作圆周运动，这有利于自来水与浓水的充分混合，提高供入滤膜件20的浓水侧22的水的均匀度。
 本发明的实施方式
本发明提供了两种混水装置10的具体结构：
实施例1
如图1所示，在本实施例中，柱状腔室被配置成自尾部到头部径向尺寸均匀减小的锥柱状腔室，在该结构中，水在锥柱状腔室内作圆形运动的同时还朝向混水装置10的出液口123方向流动，该结构使得水能够在获得混合的同时还能够顺畅的经过混水装置10。
实施例2
如图2至图5所示，在本实施例中，柱状腔室被配置成自尾部到头部径向尺寸分段减小的柱状腔室，下面具体描述具有该特点的混水装置10的具体结构。
该柱状腔室由四个隔板分成五个（段）轴向排布的子腔室，即，第一隔板131、第二隔板132、第三隔板133以及第四隔板134将柱状腔室分成从尾部到头部依次排布的第一子腔室141、第二子腔室142、第三子腔室143、第四子腔室144以及第五子腔室145。自第一子腔室141到第五子腔室145，各腔室的径向尺寸分段变小。自来水进液口121和浓水进液口122形成于第一子腔室141所对应的柱状壳体11上。
第一隔板131的中部形成有镂空洞1311；第二隔板132的边缘形成有周向排布的多圈过流孔1321；第三隔板133的中部形成有镂空洞1331；第四隔板134的边缘形成有周向排布的多圈过流孔1341。
与第二隔板132相邻区域的第三子腔室143形成有锥形结构；与第四隔板134相邻区域的第五子腔室145也形成有锥形结构。
在柱状壳体11的尾部的端面处安装有能够照射第一子腔室141的紫外线杀菌灯15；在靠近柱状壳体11的头部的壳壁上装设离子浓度器16，该离子浓度器16的探头径向的伸入至第五子腔室145内以用于检测其中的水的离子浓度。
在第一隔板131的边缘处开设有周向排布的多圈气孔1312，该气孔1312包括喇叭部13122和缩口部13121，该喇叭部13122朝向第一子腔室141。
如图3所示，来自自来水管43的自来水经由自来水进液口121进入到柱状壳体11的第一子腔室141，来自浓水侧22的浓水经由浓水进水口进入到柱状壳体11的第一子腔室141，因自来水进液口121和浓水进液口122均与第一子腔室141相切，且两者朝向相反，这使得进入到第一子腔室141的自来水和浓水在第一子腔室141内作同向的圆周运动，这有利于自来水与浓水的混合。同时，紫外线杀菌灯15对第一腔室内的水进行杀菌消毒。
如图4所示，气体由气孔1312的喇叭部13122收拢并经由缩口部13121而排出到第二子腔室142中，进而避免气体存留于第一子腔室141内而对圆周运动的水产生阻力，影响水的混合。
在与柱状壳体11的出液口123连接的水泵30的负压吸附作用下和/或第一子腔室141内的水压作用下，第一子腔室141内的水通过位于第一隔板131中央的镂空洞1311进入到第二子腔室142内，然后，再通过位于第二隔板132的边缘的多圈过流孔1321进入到第三子腔室143中，由于第一隔板131的镂空洞1311位于中央，而第二隔板132的过流孔1321位于边缘，这使得经过第二子腔室142的水流改变了方向，在一定程度上提高了水混合的均匀度。
水通过第二隔板132的边缘的过流孔1321后流向第三子腔室143的锥形结构，该锥形结构使得水流改变方向而朝向第三腔室的中部流动，改变流向的水经过第三隔板133中央的镂空洞1331而进入到第四子腔室144中。水在经过第三子腔室143过程中因改变了流向而提高了水混合的均匀度。
同样地，水经过第三隔板133的镂空洞1331而进入到第四腔室后，再经过第四隔板134的边缘的过流孔1341而进入到第五子腔室145中，水在经过第四子腔室144时，水流方向也发生改变，进一步提高了水混合的均匀度。
水通过第四隔板134的边缘的过流孔1341后流向锥形结构，该锥形结构使得水流方向改变而朝向第五腔室的中部流动，最终从出液口123流出而直接或者借由水泵30供入滤膜件20的浓水侧22。
应该说明的是：
1、实施例2所提供的混水装置10使水的混合的均匀度要高于实施例1所提供的混水装置10。
2、虽然实施例2所提供混水装置10对降低节流压力的程度小于实施例1，但实施例2所提供混水装置10也足以令换向阀50在较低的节流压力下工作，换向阀50依然能够较准确的控制浓水的流量和流速。
水泵30设置在第三回水管路44上，该水泵30为自吸水泵30以用于将混合后的水以一定的压力供入滤膜件20的浓水侧22。
流量阀61和电磁开关阀62并列设置于自来水管43上，在需要制备直饮水时，首先使电磁开关阀62打开，这使得自来水迅速经过混水装置10而流向水泵30，并供入滤膜件20以建立足够的水压，当浓水侧22的水压建立后，关闭电磁开关阀62而使流量阀61打开并调节流量阀61的开度以控制自来水的供给流量。
第一流量计81设置于自来水管43上，第二流量计82设置在第二回水管路42上；第一流量计81用于测量供入混水装置10的自来水的流量，第二流量计82用于测量供入混水装置10的浓水的流量，并结合流量阀61可维持自来水与浓水的混合比例、调节自来水与浓水的混合比例以及维持水的总供给量。例如，若第二流量计82检测到浓水的流量降低，为了维持水的总供给量而调节流量阀61以提高自来水的流量。
过滤器70设置于第一流量计81的上游的自来水管43上，该过滤器70用于过滤自来水的杂质；杀菌器92设置在第一出水管路441上以用于对直饮水进行杀菌。
本发明所提供的净水***的优势在于：
1、净水***中的混水装置10能够有效降低节流压力，提高换向阀50对浓水流速和流量的控制精度。
2、通过设置流量阀61、第一流量计81和第二流量计82而能够调节自来水与浓水的混合比例以及水的总供给量。
3、实施例2所提供的混水装置10具备如下优势：
1）、通过在柱状腔室内设置隔板而将柱状腔室分隔成多个子腔室，通过使相邻隔板在中央开设镂空洞和边缘开设过流孔1321，进而使得经过子腔室的水流的方向不断发生改变，进一步提高了水混合的均匀度。
2）、在柱状壳体11的尾部装设紫外线杀菌灯15，该线杀菌灯能够有效杀灭水中的细菌，且能够有效抑制柱状腔室内滋生细菌。
3）、自来水与浓水在柱状腔室内获得均匀混合，这使得离子浓度器16所检测的离子浓度较准确，有效防止了检测数据出现漂移。
4）、经过混合装置所获得均匀度较佳的水通入滤膜件20的浓水侧22后能够有效降低滤膜件20的极差化的程度，提高了直饮水的水质。
5）、在隔板上开设气孔1312能够更大程度的将作圆周运动的水中的气体排出，降低了气体对水混合过程的影响。将气孔1312设置成喇叭状有利于收拢更多的气体。
