Description

带加热和UV杀菌功能净水器的UV杀菌控制方法 技术领域
本发明涉及一种带加热和UV杀菌功能的净水器，特别是一种带加热和UV杀菌功能净水器的UV杀菌控制方法。
背景技术
近几年来，净水产品作为健康产品越来越受到消费者的关注，净水行业也随之在高速地发展。净水器出水二次污染的问题越来越受到消费者的关注。UV杀菌技术是解决出水二次污染的其中一项技术，在净水器出水时，通过UV杀菌技术可以把净水器内长时间存储的水里滋生的细菌杀灭。
现有的UV灯控制方法，有的是在净水器上电时就一直点亮UV灯，从不关闭；有的是与用户取水开关联动，当用户打开水龙头取水时，UV灯点亮，当用户关闭水龙头停止取水时，UV灯关闭。
技术方案一所述的UV灯控制方法简单，易实现。但是，UV灯有一定的点灯时长寿命和启动次数寿命。如果UV灯一直点亮，那它的点灯时长寿命将很快到达而损坏或大大降低杀菌效果，另外，水被UV灯长时间照射后，水温会有所上升，口感也会变差。如果UV灯在每次取水都启动一次，那它的启动次数寿命将很快到达而损坏，另外，如果净水器长时间不使用，在UV灯所在的管路上的一段水里滋生的细菌，当取水时由于出水过快照射时间不够，杀菌效果也不好。
发明内容
本发明的目的在于克服上述现有技术存在的不足，而提供一种通过智能控制UV灯的启闭，既能延长UV灯的使用寿命，又能保证良好的杀菌效果，控制方式更节能环保的带加热和UV杀菌功能净水器的UV杀菌控制方法。
本发明的目的是这样实现的：
一种带加热和UV杀菌功能净水器的UV杀菌控制方法，所述净水器包括净水水路系统和电控系统，净水水路系统中设有水加热装置和水杀菌用UV灯，电控系统带有计时功能，电控系统分别与水加热装置和UV灯电性连接；其特征是，所述UV杀菌控制方法结合UV灯启闭的时间长短和出水温度情况来适当控制UV灯开启的时间和控制UV灯关闭工作的时间，以避免UV过长时间做无用功和避免UV灯在短时间内反复的启闭变换。
本发明的目的还可以采用以下技术措施解决：
作为更具体的方案，上电时，电控系统控制UV灯开启时间t1，在t1时间内，如果没有取水，则经过时间t1后UV灯关闭。避免UV灯长期点亮，尤其是在水质良好的情况下长期点亮，从而避免UV灯做无用功，并且缩短其使用寿命，以及造成水体发热。
如果在时间t1内有取用水温低于T的低温水，则在取水过程中UV灯持续点亮，在取水结束后延时时间t2，电控系统控制UV灯关闭。取水后的UV灯延时点亮是为了避免在频繁取用低温水时UV灯频繁地开启、关闭交替动作，以致影响UV灯使用寿命。
作为更具体的另一方案，所述净水水路系统中还设有水质检测装置，水质检测装置与电控系统电性连接，所述UV杀菌控制方法还结合水质情况来适当控制UV灯开启的时间和控制UV灯关闭工作的时间。同样可以避免UV灯长期点亮而带来上述的不良影响。
上电时，电控系统通过水质检测装置检测净水水路系统内水质情况，如果水质在合格范围内，则不启动UV灯，如果水质不在合格范围内，则启动UV灯。
待机时，在UV灯关闭状态下，电控系统通过水质检测装置持续检测净水水路系统内水质情况，如果水质在合格范围内，则不启动UV灯，如果水质不在合格范围内，则启动UV灯。
作为进一步的方案，待机时，在UV灯关闭状态下，如果取用水温低于T的低温水，则在取水过程中UV灯持续点亮，在取水结束后延时时间t2。
待机时，在UV灯关闭状态下，如果持续时间t3都没取过水，则UV灯开启(避免水体因长时间因没有流动而导致细菌繁殖过量)，UV灯开启时间t4后关闭。
如果在时间t4内有取用水温低于T的低温水，则在取水过程中UV灯持续点亮，在取水结束后延时时间t2，电控系统控制UV灯关闭。
如果在时间t2内再次取水温低于T的低温水，则在取水过程中UV灯持续点亮，在取水结束后延时时间t2，电控系统控制UV灯关闭；如此类推，如果用户设置的出水温度高于T，则在取水过程中UV灯熄灭；水温T为具有杀菌功效的温度。此方式可以有效避免重复杀菌功能的启动，从而减少UV灯的使用次数，延长其使用寿命。
本发明的有益效果如下：
本发明所展现的UV灯控制方案，通过智能控制UV灯的启闭，既能延长UV灯的使用寿命，又能保证良好的杀菌效果，保证用户的饮水安全的同时，并能维持水原有的口感。当出水水温较高足以杀死细菌时，UV灯不开启，减少UV灯的工作时长，又节能环保。

图1为本发明中带加热和UV杀菌功能净水器的结构示意图。
图2为本发明中带加热和UV杀菌功能净水器另一状态的结构示意图。
具体实施方式
下面结合附图及实施例对本发明作进一步描述：
实施例一，参见图1和图2所示，一种带加热和UV杀菌功能净水器6的UV杀菌控制方法，所述净水器6包括净水水路系统1和电控系统，净水水路系统1中设有水加热装置5、水杀菌用UV灯3和水质检测装置2，电控系统带有计时功能，电控系统分别与水加热装置5、UV灯3和水质检测装置2电性连接；所述电控系统包括相互电性连接的控制板7和操作面板4；所述净水器6设有取水口61，取水口与水加热装置5和水杀菌用UV灯3串联。所述UV杀菌控制方法结合UV灯3启闭的时间长短、出水温度情况和净水水路系统1内水质情况来适当控制UV灯3开启的时间和控制UV灯3关闭工作的时间，以避免UV过长时间做无用功和避免UV灯3在短时间内反复的启闭变换。
上电时，电控系统控制UV灯3开启时间t1，在t1时间内，如果没有取水，则经过时间t1后UV灯3关闭，如果在时间t1内有取用水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2，电控系统控制UV灯3关闭。或者，上电时，电控系统通过水质检测装置2检测净水水路系统1内水质情况，如果水质在合格范围内，则不启动UV灯3，如果水质不在合格范围内，则启动UV灯3。以上两种上电的操作可以在出厂时设定任意一种，或者，再出厂后净水器6上电使用时，需要用户通过操作面板4向控制板7输入其中一种方式。
待机时，在UV灯3关闭状态下，电控系统通过水质检测装置2持续检测净水水路系统1内水质情况，如果水质在合格范围内，则不启动UV灯3，如果水质不在合格范围内，则启动UV灯3。
待机时，在UV灯3关闭状态下，如果取用水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2。
待机时，在UV灯3关闭状态下，如果持续时间t3都没取过水，则UV灯3开启，UV灯3开启时间t4后关闭。如果在时间t4内有取用水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2，电控系统控制UV灯3关闭。
如果在时间t2内再次取水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2，电控系统控制UV灯3关闭；如此类推，如果用户设置的出水温度高于T，则在取水过程中UV灯3熄灭；水温T为具有杀菌功效的温度。
所述的时间t1～t4的值可以根据实际情况调整，可以相等也可以不等。
实施例二，与实施例一的不同之处在于是：本带加热和UV杀菌功能净水器取消水质检测装置及有关水质的检测。上电时，电控系统控制UV灯开启时间t1，在t1时间内，如果没有取水，则经过时间t1后UV灯关闭，如果在时间t1内有取用水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2，电控系统控制UV灯3关闭。
待机时，在UV灯3关闭状态下，如果取用水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2。
待机时，在UV灯3关闭状态下，如果持续时间t3都没取过水，则UV灯3开启，UV灯3开启时间t4后关闭。如果在时间t4内有取用水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2，电控系统控制UV灯3关闭。
如果在时间t2内再次取水温低于T的低温水，则在取水过程中UV灯3持续点亮，在取水结束后延时时间t2，电控系统控制UV灯3关闭；如此类推，如果用户设置的出水温度高于T，则在取水过程中UV灯3熄灭；水温T为具有杀菌功效的温度。
所述的时间t1～t4的值可以根据实际情况调整，可以相等也可以不等。
以上两个实施例中各点或类似的改动都是对本发明所述技术方案精神的延伸，都应落入本发明权利要求范围。
