本申请要求2018年05月25日申请的，申请号为201810517831.4，名称为“一种净水系统、净水方法及装置”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及净水技术领域，具体而言，涉及一种净水系统、净水方法及装置。
背景技术
目前，净水机由于其在去除泥沙、异味、重金属、有机物以及细菌病毒等方面均具有很好的效果，因此得到了广泛的应用。但是，净水机中的水如果长期不流通即不被使用的话，会储存在压力通、滤芯以及管路中，引起大量的细菌滋生，造成净化水的二次污染，最终导致用户饮用的水细菌超标，不利于用户的身心健康。
反渗透净水机在制备完纯水后，停机的过程中，反渗透膜元件内聚集有原水、浓缩水以及纯水。由于反渗透膜元件的双向渗透效应，会导致自身内的纯水的TDS(Total dissolved solids，溶解性总固体)值逐渐升高。当再次使用反渗透净水机时，上述TDS值逐渐升高的纯水会排出供用户饮用，不利于用户的身心健康。
针对现有技术中当净水机长期不被使用或停机后重新使用时，容易导致饮用水细菌超标以及初期产水的TDS偏高的问题，目前尚未提出有效的解决方案。

具体实施方式
下面结合附图和具体实施例对本申请作进一步详细描述，应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本申请的说明，其本身没有特定的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
为了解决现有技术中当净水机长期不被使用或停机后重新使用时，容易导致饮用水细菌超标以及初期产水的TDS偏高，不利于用户身心健康的问题。本申请提供了一种净水系统，如图1所示，其中，净水系统包括：电控板100、第一电磁阀10、第一逆止阀11、精密过滤器12，且图2示出了根据本申请实施例的一种净水系统的结构示意图。
如图1和图2所示，电控板100，与第一电磁阀10连接，用于控制第一电磁阀10的开闭；
第一电磁阀10，与后置滤芯8连接，用于控制后置滤芯8末端管路的纯水经第一逆止阀11排出；
精密过滤器12，与第一电磁阀10连接，用于防止排水管路的细菌回落污染纯水，其中，排水管路是位于精密过滤器12上方的管路；
第一逆止阀11，与精密过滤器12连接，用于防止排水管路的浓水回流污染纯水。
由此，净水系统可以通过控制第一电磁阀10，进而控制后置滤芯8末端管路中长期存留的纯水经第一逆止阀11排出，其中，被排出的纯水是TDS值较高以及细菌较高的纯水，以防止用户饮用该纯水。进一步地，精密过滤器12用于防止排水管路的细菌回落污染纯水；第一逆止阀11与精密过滤器12连接，用于防止排水管路的浓水回流污染纯水。由此，可进一步保证用户饮用的水细菌不超标，且安全无污染，保障了用户的身心健康。
在净水系统中，制水过程不是持续不断，而是分时段的。当制水停止时，已制备的纯水如果在一定时间内不被用户使用的话，会静置存留在净水系统中，不流通的水会造成细菌的滋生。且由于反渗透膜元件的双向渗透效应，会导致纯水的TDS值逐渐升高，影响用户的身心健康。本申请实施例中的电控板100可以向第一电磁阀10发送信号，来控制第一电磁阀10的开闭，从而使后置滤芯8末端管路的纯水经第一逆止阀11排出，而不 会被用户取用。
其中，精密过滤器12为过滤精度小于或等于特定微米的过滤膜，例如，过滤精度为0.22微米。上述特定微米的数值可根据实际需求进行设定。需要说明的是，精密过滤器12具有一定的过滤方向，以图1和图2为例对此作进一步说明。后置滤芯8末端管路的纯水依次经过第一电磁阀10、精密过滤器12、第一逆止阀11排出，精密过滤器12不会对从下至上流过的水进行过滤和阻隔。而会对位于精密过滤器12上方的排水管路中可能掉落到下方的细菌进行阻隔。由此，进一步减少了纯水中的细菌，更好地保障了用户的身心健康。需要说明的是，在具体应用中，可利用废水的排出口将上述纯水排出，也可设置新的排出口。图2以纯水排出口和废水排出口合一设置为例。
可以理解的是，后置滤芯8末端管路的纯水是已经经过三级过滤，并经过后置滤芯8过滤的水。即使会由于不流通而存在细菌，也不等同于废水。且后置滤芯8可以是复合滤芯，具有较强的过滤效果。也可以是活性炭或者碳棒。
在一种可能的实现方式中，电控板100，还用于在净水系统处于停止制水模式时，周期性或间歇性的向第一电磁阀10发送开启信号和关闭信号；其中，开启信号和关闭信号之间间隔第一预设时长；第一电磁阀10，还用于在接收到开启信号的情况下，在第一预设时长内控制后置滤芯8末端管路的纯水经第一逆止阀11排出。
其中，当净水系统处于制水模式时，如果进行排水，则排水过程会和制水模式互相干扰，甚至影响净水系统的正常使用，从而缩短净水系统的使用寿命。因此，需要当净水系统处于停止制水模式时，再进行排水。
其中，当电控板100，用于周期性的向第一电磁阀10发送开启信号和关闭信号时，周期可以在1小时到24小时之间任意取值，第一预设时长可以在1分钟至60分钟之间任意取值。周期和第一预设时长可直接采用出厂时的设置参数，也可由用户根据实际需要进行选取和设定。如果用户取水较为频繁，则周期可相对较长；如果取水量较少，则第一预设时长可相对较短。
表1示出了在不同的间隔取样时间、排水周期(周期)为4小时、排水时间(第一预设时长)为2分钟；排水周期(周期)为8小时，排水时间(第一预设时长)为4分钟时，净水系统末端出水细菌总数的值以及第一杯水中的TDS值。其中，净水系统末端出水即为用户通过水龙头13接出的水。

由以上表格可知，排水时间随着排水周期的增大而增大，当排水周期增大时，需要较长的排水时间，才能保证将初期细菌较高和TDS值较高的纯水排出。由此，可保证净水系统末端出水的细菌不超标且TDS值处于标准饮用值之内，保证用户的身心健康。
当电控板100用于间歇性的向第一电磁阀10发送开启信号和关闭信号时，本次排水和下一次排水之间的间隔时间并不固定，例如，该间隔时间可以呈逐渐递增趋势。在具体的应用性示例中，白天用户取水较为频繁，可将间隔时间逐渐加大，以避免循环模式影响用户的正常取水。
综上所述，周期性或间歇性的控制第一电磁阀10进行排水更加符合用户的实际需要和净水系统的工作状态，有利于节能，且避免了无用功。且由用户参与设置参数(周期和第一预设时长)，而不是将参数固定化，更具智能性，进一步提升了用户的使用体验。
在一种可能的实现方式中，电控板100，还用于获取用户的用水时间信息，根据用水时间信息确定发送开启信号和关闭信号的时间，以使得第一电磁阀10在用户取水前完成工作。
为了获取用户的用水时间信息，可设置采集芯片，以自动采集用户的用水频率和时间段，并将这些信息发送至电控板100或将采集芯片集成到电控板100上。以使得上述排纯水的过程避开用户的用水时间段和净水系统的制水时间段，以避免净水系统出现当多种模式同时执行时导致的水路干扰情况。且根据用户的用水习惯自动进行排水，可保证被用户饮用的水质时刻处于鲜活无污染状态。
以具体的应用性示例进一步说明获取用户用水时间信息的作用。用户在夜晚时，处于 睡眠状态，通常情况下，用户取水的概率较低。而白天时，用户的用水概率相对较高。则可在白天将排水周期设置为1至2小时，第一预设时长设置为1至5分钟。进一步地，控制排水过程在用户取水前的1分钟到60分钟时开启。例如，如果用户在下午1点取水，则控制排水过程在此之前开启，保证在用户取水时，排水过程已完成，水质处于鲜活无污染的状态。
在一种可能的实现方式中，电控板100，还用于在监测到用户取水时，向第一电磁阀10发送关闭信号。
举例来说，可设置一个脉冲流量计来监测用户是否正在取水，并将用户取水的信号反馈至电控板100。电控板100可以在接收到用户取水的信号后，向第一电磁阀10发送关闭信号，停止排水。由此，用户可以在水龙头13处取水，不会对用户的取水造成干扰。且可以如上述实现方式中所述，根据用户的用水习惯，使排水过程避开用户的取水时段，在保证用户饮用的水安全无污染的同时，避免对用户的取水造成干扰。
需要说明的是，脉冲流量计只是对采用何种方式监测用户取水的举例说明，并不对本申请构成限制。
在一种可能的实现方式中，如图2所示，净水系统还包括：依次连接的第一级滤芯1、第二级滤芯2、第三级滤芯3、第二电磁阀4、稳压泵5、反渗透膜6、第二逆止阀7、后置滤芯8、水龙头13，以及，与反渗透膜连接的废水比电磁阀9。净水系统还包括高压开关14以及与高压开关14连接的压力桶15，其中，压力桶15用于储水。
其中，第一级滤芯1可以为PP棉、第二级滤芯2可以为颗粒活性炭、第三级滤芯3可以为压缩活性炭。净水系统可通过废水比电磁阀9排出浓水(废水)，并通过废水比电磁阀9调节排浓水的流量。压力桶15和高压开关14可构成储水系统。净水系统制备的水可储存在压力桶15中，保证当用户需要取水时，可立即从压力桶15中取水，无需等待净水系统制水。可以理解的是，压力桶15和高压开关14不是净水系统所必需的。
该实现方式中的结构为现有的净水系统的结构，在此不再赘述。

步骤S202、当净水系统处于停止制水模式时，通过控制第一电磁阀开启，从而将后置滤芯末端管路的纯水经第一逆止阀排出；其中，第一逆止阀用于防止排水管路的浓水回流；以及
步骤S203、控制精密过滤器的过滤方向，以防止排水管路的细菌回落污染纯水，其 中，排水管路是位于精密过滤器上方的管路。
其中，步骤S202、当净水系统处于停止制水模式时，通过控制第一电磁阀开启，从而将后置滤芯末端管路的纯水经第一逆止阀排出包括：当净水系统处于停止制水模式时，周期性的控制第一电磁阀的开启和关闭；其中，第一电磁阀从开启到关闭持续第一预设时长，以使得第一电磁阀在第一预设时长内控制后置滤芯末端管路的纯水经第一逆止阀排出。
