附图说明
图1为本发明一实施方式中一种光控分体式非承压太阳能热水装置的结构示意图。
具体实施方式
下面结合说明书附图，对本发明进行进一步详细的说明。
如图1所示，
一种光控分体式非承压太阳能热水装置，包括水箱10、集热器20和微电脑控制仪30，水箱10和集热器20为分体式结构，水箱10包括外壳和内胆，外壳和内胆之间设有保温层15，水箱10的侧壁设有第一进水口13和第一出水口12，第一进水口13设置高度高于第一出水口12，集热器20包括第二进水口21和第二出水口22，第一出水口12与第二进水口21通过第一管路61连通，第二出水口22与第一进水口13通过第二管路62连通，第一管路61上依次设有单向阀40、循环泵34和第一电磁阀35，循环泵34与微电脑控制仪30连接，第一电磁阀35与微电脑控制仪30连接，集热器20设有光强传感器31，光强传感器31与微电脑控制仪30连接。
其中，水箱10包括外壳和内胆，外壳和内胆之间设有保温层15，保温层15填充有保温材料，和电热水器的保温水箱一样选择PE闭孔发泡材料。因为太阳能热水器只能白天工作，而人一般在晚上才使用热水，所以必须通过保温水箱把集热器在白天产生的热水储存起来。水箱10的安装位置比较灵活，可以社会在阳台边侧的洗涤台下或者储藏间内，可做成圆柱体或长方体，体积可以根据集热器表面积配套确定。
其中，微电脑控制仪30为控制整个装置的中枢，采用微电脑专用控制程序控制，根据光强传感器、水位传感器、水流微压传感器传来的信号，精确控制水箱10的补水、循环水泵34、电磁阀的通断，以实现整个装置的连续、间断运行及正常用水需要。
其中，集热器20采用框架水平设置的真空集热管分装在左右两侧，真空集热管内加装不锈钢底部的进水管，进水从框架中间立柱下部沿着真空集热管内的不锈钢进水管，从两外侧朝中间缓慢充满整个集热器。集热器20可安装在阳台护栏外侧或坡屋顶上，但位置必须高于水箱10，否则不利于无光时水的回流。
循环水泵34用以实现水流的加热循环和正常用水的增压需要，依据集热器20大小，选定泵的输入功率。单向阀40允许水流从水箱10进入集热器20，而可以防止其逆流。
进一步的，水箱10顶部设有第一水位传感器32，水箱10底部设有第二水位传感器33，第一水位传感器32与微电脑控制仪30连接，第二水位传感器33与微电脑控制仪30连接。
进一步的，水箱10顶部设有第三进水口11，第三进水口11通过第三管路63与水源连通，第三管路63上设有第二电磁阀36，第二电磁阀36与微电脑控制仪30连接。
进一步的，还包括出水开关50，出水开关50与第一管路61通过第四管路64连通，第一管路61和第四管路64的连通点位于循环泵34和第一电磁阀35之间，第四管路64上设有微压传感器37，微压传感器37与电脑控制仪30连接。
其中，第一管路61、第二管路62、第三管路63和第四管路64均可采用PP-R管。
进一步的，水箱10的顶部设有溢流口14。
具体的，溢流口14可以直接连接的建筑的排水系统中，当水箱10的水受热膨胀时，可以将多余的水排出水箱10。
工作原理：早晨当设置在集热器10上的光强传感器31检测到一定光强的太阳光时，微电脑控制仪30启动运行。检查水箱10的水位，如水未达到低水位，第二水位传感器33就发出信号给微电脑控制仪30，微电脑控制仪30打开第二电磁阀36给水箱10补水，水加到高水位后，第一水位传感器32发出信号，微电脑控制仪30关闭第二电磁阀36，补水结束。接着 启动循环水泵34，打开第一电磁阀35给集热器20上水，到设定的上水时间，微电脑控制仪30关闭循环水泵34和第一电磁阀35，此时集热器20中的水静止吸热升温，然后根据光强的不同定时进行循环换水。如光强未达到设定值，微电脑控制仪30自动延时一定时间后，打开第一电磁阀35，集热器20及管路中的水利用水位落差流回到水箱10，使整个装置的水全部回到水箱10保温，这样整个装置处于待机状态，当光强又一次达到设定要求时，整个装置重复上述循环。
在白天有光正运转的时段，只需打开出水开关50就能用上热水；当无光或者晚上整个装置处于待机状态时，打开出水开关50，第四管路64的结存的水就从第四管路64流出，从而带动水流微压传感器37产生信号，微电脑控制仪30控制循环水泵34运转，此时第一电磁阀35关闭，压力水从第四管路64源源不断送来。关闭出水开关50，水流微压传感器37信号消失，循环水泵34停止运转，第四管路64上结存部分水以备下次使用。
本发明提供的实施方案中的一种光控分体式非承压太阳能热水装置能利用光照强弱及持续时间自动控制水流的无压力循环、回流，克服了一体机水性保温性能差、承压分体机易泄露等缺点，其应用前景光明。
以上表述仅为本发明的优选方式，应当指出，对本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些也应视为本发明的保护范围之内。
