Description

说 明 书 一种循环节水系统 技术领域
本实用新型涉及循环节水系统技术领域，具体涉及一种用于卫浴 场所的节水系统。 背景技术
根据调查， 卫浴间是一般家庭用水量最多的地方， 其之用水量约 占家庭用水量的 70 % ~ 80 %左右， 而卫洛间的用水量又是以马桶水 箱及洗澡设备（如莲蓬头或浴缸等）的用水量最多， 其中马桶用水量 约占用卫洛间用水量的 40 %左右， 洗澡设备的用水量亦约占用卫浴 间用水量的 50 %左右。 因此如何节省家庭的用水便需从卫洛间着手， 而如何节省卫、浴间的用水主要系需着重在该马桶水箱及洗澡设备上。 在一个家庭中洗澡设备的用水量仅能从个人的习惯下去改善，其改善 的成效不大，而马桶水箱的省水方面，目前巿面上虽有很多省水马桶， 但是其大都是将马桶水箱设计成两段式的方向着手，即冲释尿液可用 较少的冲水量， 而冲粪便则可用较大的冲水量。 然而该两段式马桶水 箱的省水方式即使再如何的省水， 其仍然需要用掉一定量的水， 才能 保持马桶的干净， 所以该省水马桶的省水量约仅只有原来的 2 ~ 3成 左右， 对于卫洛间的省水效果来讲成效不大。 另外， 一般在利用莲蓬 头淋洛时， 该莲蓬头因为热水器及其间管路的关系， 其一开始喷出的 水通常是冷的， 需经过一段时间才会渐渐喷出热水。 因此利用该莲蓬 头淋浴时， 一般会先将刚开启时的冷水或水温不够热的水排放掉， 直 到水温达到所需时才开始用其来淋浴。 然而， 如此便会浪费大量的水 资源。 特别是， 在使用莲蓬头淋浴时， 常会因涂抹香皂、 沐洛乳或是 因洗洛的部位不同等原因， 而需暂停使用该莲蓬头喷出的水。 因此为 了避免该莲蓬头断续的开开关关而产生上述等待热水或需重新调温 的情形， 通常使用者会将该莲蓬头持续的打开而不会关掉， 而如此更 是会进一步造成水资源的浪费。
实用新型内容
本实用新型要解决的技术问题是提供一种不影响正常使用、节水 效果好、 节水量大的循环节水系统。
为解决上述技术问题， 本实用新型釆用如下技术方案： 一种循环 节水系统， 其特征在于： 该节水系统与淋浴喷头、 双节水箱、 洗脸池 及马桶水箱构成用水循环系统， 其包括一净水收集器、 一净水箱、 一 中水箱 （即双节水箱）， 净水收集器设于喷头下方， 净水收集器由管 道连接净水箱， 净水箱分别连接洗脸池和马桶水箱； 在喷头下方的地 面上设有一汲水器， 汲水器通过管道连接中水箱， 在该管道上设有过 滤器， 中水箱连接马桶水箱； 净水箱还连接自来水管； 净水箱设有一 净水溢流口， 净水溢流口连接中水箱。
优选地， 净水箱连接马桶水箱的管道先连接到一切换阀， 中水箱 连接马桶水箱的管道也先连接到该切换阀，再通过管道从切换阀连接 到马桶水箱。
优选地， 在净水收集器的管道上设有温度显示器。
优选地， 中水箱设有一中水溢流口， 中水溢流口通向外界， 中水 溢流口的高度低于净水溢流口。
优选地，在净水箱有设有一浮水开关补水器， 该补水器通过管道 与自来水水源连接。 优选地， 在中水箱有设有一浮水开关补水器，该补水器与净水箱 连接。
优选地， 在洗脸池的出水管上设有一自吸泵或电动汲水泵， 该自 吸泵或电动汲水泵通过管道连接中水箱。
优选地， 中水箱连接切换阅的管道与给花圃浇水的浇灌管连接。 优选地， 中水箱底部设有可以将中水放空的中水出水口。
喷头可以转动， 洗澡时， 先将喷头转到对准净水收集器， 打开喷 头阀门， 喷头喷出的冷水进入净水收集器， 再经过管道流到净水箱， 一段时间之后，喷头开始喷出热水，温度显示器会实时显示水的温度, 通过观察温度数值或温度指针可判断水是否够热了（如洗澡水的温度 一般为 45 °C左右）， 如水温够热了就将喷头转向用于洗澡； 同样在抹 沐浴露时如不将水关闭， 也可以将喷头转到对准净水收集器收集水， 收集到的水也流到净水箱， 因此净水箱收集到水是干净的， 既可以用 于洗脸， 也可用于冲洗马桶， 如收集满了则通过净水溢流口流到中水 箱中， 如果净水箱中没有收集到水， 净水箱内的浮水开关感知到水位 不足， 则可以通过自来水管补充水。 在洗洛过程中， 喷头喷出的水淋 过人体后流到地面的汲水器上， 人站在汲水器表面上洗澡， 通过人踩 踏汲水器产生的压力差或另外安装电动泵浦可以将流到汲水器上的 水经管道输送到中水箱中， 可用于冲洗马桶， 也可用于浇花等， 如果 中水箱中没有收集到水，中水箱内的浮水开关感知到水位不足， 则可 以通过净水箱补充水；用净水或者中水来冲洗马桶可以通过切换阀来 选择； 另外， 洗脸时流出的水也可以通过自吸泵再输送到中水箱中。 即双节水箱内如果存水不足， 可以利用浮力开关感知到， 进而从自 来水源自动朴充水， 因为水源是自然流动， 马桶或洗手盆水龙头永 远供水充足。
本实用新型通过净水收集器收集干净的水， 可以用来洗脸洗手， 也可以用来冲洗厕所； 通过汲水器、 电动泵浦和自吸泵收集使用过的 中水， 可以用来冲洗厕所， 也可以用来浇花浇草等； 经验证， 釆用本 系统后一个四口之家每天至少可以收集干净水 10升、 中水 100升， 也就是说相当每天节水 110升， 一年下来至少 4万升， 即 40立方米， 如果能够在全国推广两千万个家庭使用， 那么一年可节水 8 亿立方 米， 相当于一个中大型水库的容量， 可见社会效益和经济效益是非常 巨大的。 附图说明
