下面参考附图描述根据本发明实施例的净水设备1。
如图1所示,根据本发明实施例的净水设备1包括净水滤芯100、水龙头400、水泵500、回水管600、通断阀700、控制器800。
净水滤芯100上连接有进水管200和出水管300,进水管200与原水水源连通。水龙头400通过出水管300与净水滤芯100相连,水龙头400上设有用于检测水龙头400是否打开的检测装置。水泵500连接在进水管200上。回水管600分别与进水管200和出水管300相连且回水管600与进水管200的连接节点位于水泵500与所述原水水源之间。通断阀700连接在回水管600上。控制器800分别与通断阀700、水泵500和所述检测装置通讯以在所述检测装置检测到水龙头400打开时控制通断阀700和水泵500开启预定时间。

下面参考附图描述根据本发明实施例的净水设备1的工作过程。
在用户需要取用净水时,将开启水龙头400,此时所述检测装置检测到水龙头400打开,向控制器800发送信号,控制器800控制通断阀700和水泵500打开,使出水管300内的存水在水泵500产生的负压下通过回水管600流回进水管200。存水再次经过净水滤芯100的过滤变为净水,经过预定时间后,出水管300内的存水全部输送回进水管200,此时通断阀700和水泵500关闭,净化后的水则通过水龙头400正常流出。
根据本发明实施例的净水设备1,通过设置净水滤芯100,能够使原水得到有效的过滤。这样可以清除自来水内的细菌、病毒、重金属、有机磷等各种有害物质,便于消除水质对人的身体健康带来的隐患,便于提高用户的用水安全性。
并且,通过设置回水管600、通断阀700和水泵500,能够在水龙头400正常出水之前,利用水泵500将出水管300内的存水通过回水管600输送回进水管200,以避免出水管300内的存水直接排出导致用户接取到放置时间较长的存水。这样在出水管300内的存水排净后,新制备的净水再通过出水管300流出,保证用户接取到新鲜制备的净水,避免用户接取到易发生二次污染的存水,实现即开即鲜,进一步提高用户的用水安全性。
此外,通过设置回水管600,能够使净水设备1的出水管300中积存的水流回到进水管200,使出水管300内的存水再次经过净水滤芯100,以使出水管300内的存水再次得到净化。这样可以使出水管300内的存水能够再次回收利用,从而可以使水资源得到充分利用,避免水资源的浪费。
进一步地,净水设备1通过设置控制器800和通断阀700,并在水龙头400上设置所述检测装置,可以在用户开启水龙头400时,利用所述检测装置检测水龙头400的开启,并通过控制器800控制所述检测装置、通断阀700和水泵500开启预定时间。这样可以通过计算或简单实验得出合理的所述预定时间,保证出水管300内的存水完全通过回水管600流回进水管200的同时减少用户等待出水的时间,由此可以实现在最短的时间内从水龙头400流出新鲜的净水,避免用户等待额外的时间,提高净水设备的自动化和智能化。
也就是说,净水设备1不仅能够避免用户接取存水,使存水得到回收利用,而且能够避免用户较长时间等待出水。
因此,根据本发明实施例的净水设备1,具有出水健康安全、水资源利用充分、避免水资源浪费等优点。
下面参考附图描述根据本发明具体实施例的净水设备1。
在本发明的一些具体实施例中,如图1所示,根据本发明实施例的净水设备1包括净水滤芯100、水龙头400、水泵500、回水管600、通断阀700、控制器800。
可选地,如图1所示,净水设备1还包括仅允许进水管200的水流入储水管的单向阀900,单向阀900连接在回水管600上且位于通断阀700与进水管200之间。由于单向阀900仅能够使净水设备1的出水管300中积存的水流回到进水管200中,而不会出现反向流动的情况,以避免进水管200内的水通过回水管600流入出水管300内,避免在原水水源处的压力大于水泵500产生的负压的情况下,导致未净化过的原水通过回水管600流入出水管300后从水龙头400排出,从而避免用户接取未净化的原水,进一步保证净水设备1出水健康安全。
有利地,如图1所示,净水设备1还包括前置滤芯1000,前置滤芯1000连接在进水管200上且位于所述原水水源和回水管600与进水管200的连接节点之间。这样可以保证原水管网中产生的泥沙、铁锈等大颗粒杂质不会进入到后续的管路中,避免后续管路和设备发生堵塞或损坏,对后续管路和设备起到保护作用。
更为有利地,前置滤芯1000为多个且多个前置滤芯1000串联设置。这样可以利用多个前置滤芯1000进行过滤,不仅可以进一步保证对原水中大颗粒杂质的粗滤效果,提高前置滤芯1000工作的可靠性,而且可以通过设置不同过滤级别的前置滤芯1000实现原水的多级过滤,进一步避免大颗粒杂质进入后续的管路和设备中,对下游的后续管路和设备等起到积极的保护作用。
具体地,如图1所示,净水设备1还包括后置滤芯1100,后置滤芯1100连接在出水管300上且在于净水滤芯100和回水管600与出水管300的连接节点之间。这样可以在水从水龙头400排出之前利用后置滤芯1100再次进行过滤,从而进一步保证出水的纯净。
更为具体地,后置滤芯1100为活性炭滤芯。具体而言,所述活性炭滤芯是一种集吸附、过滤、截获、催化等多种作用于一体的滤芯,能够有效去除水中多余的氯以及其他化学物质等污染物,而且还能去除水质的颜色和异味。这样可以利用后置滤芯1100对水中的杂质和异味进行吸附和祛除,以进一步改善水质,提高出水的口感,同时还能除去水中的颜色和异味,便于提高用户的用水体验。
具体而言,所述预定时间根据后置滤芯1100与水龙头400之间的出水管300的长度、出水管300的管径和水泵500的压力计算得出,以在保证管路内的存水能够完全排出的情况下避免用户等待额外的时间。
图1示出了根据本发明的净水设备1,回水管600与出水管300的连接节点邻近水龙头400。这样可以使出水管300中的存水能够完全从回水管600流回,从而保证用户在开启水龙头400时,能够获得新鲜的净水,而且可以避免存水直接通过水龙头400排出,进一步节约水资源。
有利地,通断阀700为电磁阀。水龙头400打开时,所述电磁阀开启,出水管300中的水通过回水管600流回。这样可以实现通断阀700的电动控制,不仅可以便于控制通断阀700的开闭,而且由于电磁阀的响应速度快,可以便于提高控制器800对通断阀700控制的灵敏度和准确性,便于提高回水管600功能切换的可靠性。
更为有利地,通断阀700为常闭电磁阀。具体而言,所述常闭电磁阀是一种在弹簧的作用下阀体是闭合的,在通电下阀体是打开的电磁阀,这样可以在需要打开通断阀700时向其供电,使水流能够通过通断阀700。这样可以便于对回水管600中的水流进行控制,进一步提高回水管600功能切换的可靠性。
图1示出了根据本发明的净水设备1,净水滤芯100为反渗透滤芯。由于反渗透滤芯的滤净率较高,这样可以便于获得高质量的净水。
