供水系统水质监控方法、供水系统及制冷设备
交叉引用
本申请引用于2019年4月17日提交的专利名称为“供水系统水质监控方法、供水系统及制冷设备”的第2019103074067号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请涉及供水系统水质监控技术领域，尤其涉及供水系统水质监控方法、供水系统及制冷设备。
背景技术
供水或提供冷却水是高端制冷设备的基本选项，但已公布的制冷设备供水系统仅完成了水过滤、水冷却、水储存和水分配功能，对于水质的判断是无能为力的，尤其是长时间闲置不用后制冷设备供水系统的水壶内的水直接提供给用户，用户体验非常不好。
请参见图1，现有制冷设备供水系统的水路结构如下：
外接水源的水流经过进水阀10后，进入过滤器11进行过滤，之后存储在水容器12内。为避免水质过早变坏，水容器12多为封闭结构。分水阀15多为一进二出结构，一路水直接给制冰机供水，另一路水经制冷设备箱体内的管路、制冷设备门体以及分配器，直接提供给消费者。
现有水路结构，无法对水壶内的水质进行检测。制冷设备一旦启动，水壶内始终充满水。当制冷设备长时间不用的情况下，水壶内的水始终无法排出，进而水中的有机物会滋生并沉积在水路及水壶内壁。为克服这一难题，制冷设备厂家基本会要求用户在制冷设备重新启用前，尽可能多的往外排水。但是沉积物一旦在水路以及水壶内壁形成，无法通过大量排水去除，此方法只会使水壶内和管路当中的杂 质浓度降低，无法从根本解决问题。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在本申请的描述中，需要说明的是，术语“中心”、“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系在没有特别说明的情况下，为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方 位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
根据本申请的其中一个实施例，提供一种供水系统水质监控方法，包括：
S1、控制向供水系统的出水管输送水。
S1可以概括为输水操作。具体的，在对供水系统中水质进行监控之前，将供水系统的水质监控系统和供水系统进行连接。进而，基于该供水系统的水质监控系统，可以控制向出水管输送水。
其中，向出水管输送水至少包括两种情况：
第一种情况，供水系统当中储存有一定量的水，此时只需要将供水系统当中储存的水输送至出水管当中即可。
第二种情况，需要通过外部水源向供水系统当中注入水，进而使得出水管处有水进入。此处的水源既可能是供水系统自带的水箱，也有可能是外部水源，例如自来水供应管。
一般情况下，在供水系统内设置增压泵/排气减压阀，并基于增压泵/排气减压阀使得水在压差作用下进入出水管。
其中，供水系统中较常设置的增压泵的类型是水泵，进而基于水泵可以在供水系统内形成水流，并使得水流进入到出水管当中。
S2、获取出水管中的水质参数。
S2可以概括为获取操作。获取出水管当中水质参数的方法有很多种。其中一种情况，可以在出水管的管路当中接入水质检测装置。进 而，基于该水质检测装置获取出水管中的水质参数。对于水质检测装置的结构，下文给出了几个具体的实施例。
S3、判定水质参数是否达标：达标，监控结束；未达标，进入下一操作。
S3可以概括为判定操作。其中，当采用水质检测装置检测水质参数是否达标的时候，水质检测装置的电极对接触水并获取水中实际电离子浓度。进一步的，将获取的实际电离子浓度和预设电离子浓度对比，当实际电离子浓度大于预设电离子浓度，判定水质参数超标；否则，水质参数达标。
其中，水质检测装置对实际电离子浓度的判断，实际上也是关于水的阻值的判断。当水质不达标时，水质杂质多，离子浓度高，水质检测装置的电阻小。因此，当水质检测装置反馈的阻值小的时候，表示此时水质不达标。反之，当水质达标的时候，此时水质检测装置反馈的阻值大。其中，对于阻值大小的判定，可以将测得的实际阻值和设定阻值做对比。
当然，水质参数不仅包括电离子浓度，例如还包括酸碱值，悬浮物含量等。其中，当水质参数指代的是电离子浓度的时候，水质检测装置的水质检测探头可以采用电极对。
S4、控制排出供水系统中的水。
S4可以概括为排水操作。通过排出供水系统中的水，使得出水管受到水流的冲刷。其中，并不要求将当前供水系统当中的水完全排尽。例如，水质参数检测不合格的原因也有可能是因为出水管处杂质堆积。此时，可能只需要对出水管进行一定时间的冲刷，就可以使得后续出水管中的水质参数达标。当然，也有可能当前供水系统储存的水完全排尽之后，出水管的水质参数仍旧不达标，此时就需要向供水系统当中再注水。
也即，为了保证供水系统中水质的监控过程中，出水管当中始终 具有水流，需要在供水系统水容器水位为零或者接近零的时候，向供水系统当中注水。
具体的，步骤S4、控制排出供水系统中的水，以及步骤S5、重复上述获取操作、判定操作和排水操作，直至水质参数达标之间，所述监控方法还包括：
检测供水系统中水容器的水位，水容器的水位为零，则控制向供水系统注入水，并将水输送至供水系统的出水管。
值得一提的是，“检测供水系统中水容器的水位，水容器的水位为零，则控制向供水系统注入水，并将水输送至供水系统的出水管”发生在步骤S4和步骤S5之间，包括两种情形：
第一种情形：“检测供水系统中水容器的水位，水容器的水位为零，则控制向供水系统注入水，并将水输送至供水系统的出水管”发生在步骤S4之后和步骤S5之前；
第二种情况：“检测供水系统中水容器的水位，水容器的水位为零，则控制向供水系统注入水，并将水输送至供水系统的出水管”和S4同时发生。
具体的，当水容器的水位为零或者接近零时，先关闭供水系统的排水阀以及供水系统的增压泵/排气减压阀。之后，开启供水系统的进水阀向供水系统注入水，并在进水阀开启之后，开启供水系统的增压泵/排气减压阀将水输送至出水管。
需要说明的是，当水容器的水位为零时，此时说明供水系统当中已经没有水流。此时，如果维持供水系统的增压泵/排气减压阀开启，将对供水系统的增压泵/排气减压阀造成损坏。由此，在向供水系统注入水之前，先关闭增压泵/排气减压阀。
并且，该种情况下，排水和注水是两个独立的过程。进而，当水质参数超标时，先将当前供水系统当中的水排尽(除非排尽前水质参数已经达标的情况)，再重新注入水，因此其可以更好实现对水质的 提高。
当然，也可以在步骤S4、控制排出供水系统中的水的同时，向供水系统注入水，使得供水系统的水容器维持设定水位。
也即，在步骤S4、控制排出供水系统中的水，以及步骤S5、重复上述获取操作、判定操作和排水操作，直至水质参数达标之间，所述监控方法还包括：
控制向供水系统注入水，使得供水系统的水容器维持设定水位。
具体的，可以在控制供水系统当中的排水阀开启以向外排水的同时，控制供水系统的进水阀开启以向供水系统注入水。
该种情况下，只要供水系统向外排水，就同时向供水系统注水，排水和注水之间不存在明显的时间间隔，进而可以提高控制水质的效率。并且，该种情况下控制简单，不需要介入对水位的监控，可以提高监控方法的可操作性和准确性。
S5、重复上述获取操作、判定操作和排水操作，直至水质参数达标。
其中，获取操作也即步骤S2对应的“获取出水管中的水质参数”。判定操作也即步骤S3对应的“判定水质参数是否达标：达标，监控结束；未达标，进入下一操作”。排水操作也即步骤S4对应的“控制排出供水系统中的水”。
该种供水系统水质监控方法，可以实时监控出水管当中的水质参数。并且，当水质参数超标时，控制排出供水系统当中的水。由此，基于该种供水系统水质监控方法，可以避免有机物在供水系统当中的滋生和沉淀，进而从根本上防止水质问题的产生，以提高供水系统的安全卫生性，保证了用户的健康。并且基于该种供水系统水质监控方法，即使长时间不使用供水系统，也不需要用户在重新启用的时候对供水系统进行排水冲洗，降低了操作难度，提高了用户使用的便利性。
值得一提的是，上述供水系统水质监控方法，可以在第一次控制 排出供水系统当中的水的时候，将供水系统当中的水排尽。而为了将供水系统当中的水排尽，最好在第一次控制排出供水系统当中的水的时候，将供水系统的进水阀关闭。而之后重复排水过程的时候，无需再将供水系统当中的水排尽，只要水质参数达标就可以停止排水。进而，在后续排水的过程当中，进水阀既可以开启也可以关闭。
也即，上述S4、控制排出供水系统中的水的步骤，包括：
控制排出供水系统当中的水，直至供水系统当中的水排尽；
上述S5、重复上述获取操作、判定操作和排水操作，直至水质参数达标的步骤，包括：
获取出水管中的水质参数；
判定水质参数是否达标：达标，监控结束；未达标，进入下一操作；
控制排出供水系统当中的水，并在供水系统当中的水排尽之前且水质参数达标的情况下，监控结束。
也即，重复排水过程，并不要求每次排水过程的排水程度相同。只需要通过排水能够对供水系统进行冲洗，进而达到改善供水系统水质的效果即可。
上述供水系统水质监控方法当中采用的供水系统的监控系统，既可以设置在供水系统当中，也可以设置在具有上述供水系统的产品当中。例如，可以将上述提到的供水系统设置在制冷设备当中。进一步的，当制冷设备为冰箱的时候，上述供水系统的监控系统可以设置在冰箱当中。
根据本申请的其中一个实施例，在步骤S1、控制向供水系统的出水管输送水之前，供水系统水质监控方法包括：
获取用水信号、清洗信号或者检测信号。
由此，该种供水系统水质监控方法，可以基于用水信号启动，也可以基于清洗信号启动，还可以仅仅基于检测信号启动。因此，即使 不用水的时候，也可以进行供水系统中水质的监控，避免长时间不用导致的供水系统中有机物滋生和沉积导致的水质变差。
当然，除了基于以上用水信号、清洗信号或者检测信号触发S1，还可以在步骤S1、控制向供水系统的出水管输送水之前：
统计供水系统的实际闲置时长，直到实际闲置时长达到设定闲置时长。
进而，当供水系统闲置过久时间的时候，具有供水系统的制冷设备可以自动发出检测信号，并基于检测信号实现对供水系统水质的监控，防止在供水系统当中滋生有机物并沉淀。
其中，对于供水系统闲置时间的统计，可以从供水系统内水流流动时清零，并当水流不再流动时开始计时。
以冰箱供水系统为例，当冰箱供水系统内水流流动，可以初步判定是冰箱供水系统处于应用或者维护状态，而非闲置。或者，也可以从冰箱供水系统当中增压泵/排气减压阀工作时清零，并从增压泵/排气减压阀工作结束时开始计时。再或者，还可以从冰箱供水系统的排水阀(也即用于向用户供水的阀，或者用于向冰箱内部提供水的阀，现有冰箱供水系统常连接一个分水阀，具体在后文提到)开启的时候清零，从排水阀关闭的时候开始计时。当然，冰箱供水系统闲置时间的统计方法不受此处举例限制。
根据本申请的其中一个实施例，步骤S5、重复上述获取操作、判定操作和排水操作，直至水质参数达标之后，监控方法还包括：
控制向供水系统注水，直至供水系统中水容器的实际水位达到设定水位。
具体的，可以通过控制供水系统的进水阀开启以向供水系统注水。
由于水质参数达标时，此时供水系统可能处于缺水状态，也即实际水位并没有达到预设水位，因此可以向供水系统注水。
其中，所述控制向供水系统注水，直至供水系统中水容器的实际水位达到设定水位的步骤，包括：
检测供水系统中水容器的实际水位，计算实际水位与设定水位之间的水位差距；
基于水位差距计算注水时长；
开启供水系统的进水阀向供水系统注水，持续时间达到注水时长。
根据本申请的其中一个实施例，提供的供水系统水质监控方法，请参见图2。
此外，根据本申请的其中一个实施例，请参见图3和图4，提供供水系统，包括水容器12以及连接水容器12的出水管路，出水管路上设置有水质检测装置13和排水阀14，供水系统还包括控制器16，水质检测装置13用于获取出水管路中的水质参数，并发送给控制器16，控制器16根据水质参数控制排水阀14，且当水质参数超标时控制排水阀14开启。
该供水系统，在水容器的出水管路上设置有水质检测装置，进而可以对供水系统的水质进行检测。进一步的，供水系统还包括有排水阀，一旦检测到水质不合格，供水系统就会基于检测结果控制排水阀进行排水，避免有机物在供水系统当中的滋生和沉积，进而从根本上防止水质问题的产生，以提高供水系统的安全卫生性，保证了用户的健康。并且该种供水系统即使长时间不使用，也不需要用户在重新启用的时候对供水系统进行排水冲洗，降低了操作难度，提高了用户使用的便利性。
通过图3和图4发现，供水系统还包括水容器12的进水管路。其中，在进水管路中设置有进水阀10。通过进水阀10可以控制整个供水系统和水源之间的通断。进水阀10的种类不限，例如可以是电控阀、磁控阀、机械阀等。
此外，在供水系统当中还可以设置过滤器11，用于对供水系统当中的水进行过滤处理，以期得到满足用户需求的水质。过滤器11应当可以设置在供水系统的任何位置，但是为了避免水容器12当中进入杂质并沉积，因此过滤器11最好设置在进水管路上，进而进入水容器12当中的水为满足用户需求的水，并且也能避免在水容器12当中产生有机物的富集和沉淀。
此外，通过图3和图4发现，出水管路上还设置有分水阀15。当供水系统为冰箱供水系统时，分水阀15的第一出口连接冰箱的制冰机，第二出口连接冰箱供水系统门体上的分配器。其中，通过设置分水阀15，进而使得用户可以利用冰箱供水系统提供的水制冰，或者可以直接通过分配器获取饮用水。当然，对冰箱供水系统水容器12供水的应用不受此处举例的限制，还可以作为任意它用。
其中，当出水管路上设置有分水阀15时，可以将分水阀15和排水阀14并联设置。请参见图3和图4，出水管路包括第一出水管18和第二出水管19。其中，排水阀14设置在第一出水管18上，分水阀15设置在第二出水管19上。图3中，水质检测装置13设置在第二出水管19上。图4中，水质检测装置13设置在第一出水管18和第二出水管19的公共进水管上。当然，图3和图4中的举例不构成对水质检测装置13位置的限制。
请参见图3，在第一出水管18上安装有水泵17，进而通过水泵17实现供水系统的抽水和送水。图4中，水泵17安装在第一出水管18和第二出水管19的公共进水管上。当然，水泵17的安装位置不受限制，可以是供水系统的任意位置。
并且，除了设置水泵17之外，也可以用任何现有技术公开的增压装置或者负压装置替代。例如，也可以在图3和图4当前泵的位置设置排气减压阀，通过在排气减压阀处形成负压，以排出供水系统当中的水。
其中，供水系统当中的水容器12可以为水壶。此时，水质检测装置13的目的在于检测水壶当中的水质是否符合要求。
此外，通过图4发现，控制器16连接用户界面20，进而可以基于用户界面20显示供水系统的情况以及接收外界指令。
根据本申请的其中一个实施例，水质检测装置包括安装管道和水质检测探头，安装管道接入管路中，水质检测探头安装至安装管道上，并伸入安装管道内；安装管道包括进水管段、出水管段以及连通进水管段和出水管段的连接管段，进水管段和连接管段之间满足：向安装管道当中通入水流时，连接管段当中的流速大于进水管段的流速；水质检测探头安装至连接管段上，并伸入连接管段内。
下面分别通过不同实施例提供几种不同的水质检测装置。
实施例一
请参见图5，实施例一的水质检测装置，包括安装管道9和水质检测探头。安装管道9包括进水管段901、出水管段903以及连通进水管段和出水管段的连接管段902。进水管段901的横截面面积大于连接管段902的横截面面积。水质检测探头安装至连接管段上，并伸入连接管段内。
该种水质检测装置通过安装管道9接入到管路当中，而非和水容器进行结合。由于传统技术水质检测装置和水容器结合处容易产生渗漏，而该种水质检测装置避免了和水容器结合，进而可以避免在结合处的渗漏。此外，该种水质检测装置，由于进水管段的横截面面积大于连接管段的横截面面积，进而连接管段当中的流速大于进水管段的流速，连接管段当中的水流实现了局部加速，使得伸入连接管段内的水质检测探头受到水流冲刷，避免在水质检测探头表面产生杂质沉积，以提高水质检测装置的检测精度。并且，由于水质检测探头不受杂质堆积影响，进而可以延长水质检测装置的使用寿命。
其中，“水质检测探头安装至连接管段上，并伸入连接管段内” 当中的“伸入所述连接管段内”指代的是“水质检测探头能和连接管段内部液体接触”的所有情形，包括水质检测探头端部和连接管段内壁平齐的情况，也包括水质检测探头的端部相对连接管段内壁凸出的情形。
请参见图5，水质检测探头为电极对3，并且电极对3同轴设置。该种情况下，两个电极受到的冲刷是一样的，进而防止在上游的电极更容易损坏。
图5中，电极对3通过导线1接入电路。
通过图5还发现，连接管段局部向外凸起形成所述电极对3的安装凹陷。将电极对3安装至安装凹陷当中，其中，电极对3包括正电极和负电极，安装凹陷的数量为两个，分别用于安装正电极和负电极。该种情况下，电极对3安装可靠，几乎不受水流冲刷影响，进而也可以延长水质检测装置的寿命。
此外，图5中，电极对3的正电极的端部和负电极的端部相对所述连接管段的内壁凸出。该种情况可以保证电极对3与水流充分接触，以对水质进行精确的检测。当然，电极对3的正电极的端部和负电极的端部也可以与连接管段的内壁平齐，进而可以避免水流冲刷电极对3，保证水质检测装置的使用寿命。
图5中，进水管段的内壁和出水管段的内壁上均设置有第一凹槽和第二凹槽。其中，第一凹槽当中固定有卡圈5，第二凹槽中固定有密封圈8。进而，通过卡圈5和密封圈8的设置，实现安装管道9与管路之间的密封连接。其中，卡圈5的作用主要在于将安装管道9和管路锁紧，密封圈8的作用主要在于实现安装管道9和管路之间的密封，防止水漏。
根据本申请的实施例一，第一凹槽位于第二凹槽远离连接管段的一侧。该种情况下，相对于安装管道9而言，第一凹槽位于第二凹槽的外侧，也即卡圈5位于密封圈8的外侧，进而可以更好的保证密封圈 8的密封效果。其中，当进水管段和出水管段的横截面呈圆形(忽略进水管段和出水管段的壁厚)时，此时密封圈8可以采用O型密封圈8。
当然，安装管道9与管路之间除了采用以上提到的卡圈5和密封圈8进行密封连接，还可以采用其它卡接方式、螺纹连接方式、焊接方式或者粘接方式等进行连接。例如，采用其它卡接方式的时候，可以将安装管道9以及管路中与安装管道9配合的管段采用卡箍卡接。再例如，采用螺纹连接方式的时候，在进水管段和出水管段的端部均设置有内螺纹/外螺纹，在管路当中设置有与其配合的外螺纹/内螺纹。
实施例二
请参见图6，和实施例一不同指出在于，实施例二当中，电极对3设置在连接管段的同一侧。该种情况下，正电极和负电极从同一侧接入外部电路，进而可以便于外部电路的设置。
其中一种情况，电极对3的正电极和负电极平行设置，并从连接管段的同一侧连接导线1。该种情况下，连接管段的结构更加的规则，进而便于制备。
实施例三
和实施例一相同之处，实施例三当中不再赘述。和实施例一不同之处在于，本实施例三当中，请参见图7，为了使得向安装管道9当中通入水流时，连接管段902当中的流速大于进水管段901的流速，进水管段901和连接管段902沿着不同轴线延伸，且进水管段901和连接管902段满足：向安装管道9当中通入水流时，进水管段当中水的重力势能高于连接管段中水的重力势能。此处，“进水管段当中水的重力势能高于连接管段中水的重力势能”是对于相同物质的量的水而言的。
由此，图7中，水流从进水管段流向连接管段时，水的部分重力势能转换成水的动能，进而使得连接管段当中水流的速度增加，并使得伸入连接管段内的水质检测探头受到水流冲刷，避免在水质检测探头表面产生杂质沉积，以提高水质检测装置的检测精度。
实施例四
和实施例三相同之处，实施例四当中不再赘述。和实施例三不同之处在于，本实施例四当中，请参见图8，电极对3设置在连接管段的同一侧。该种情况下，正电极和负电极从同一侧接入外部电路，进而可以便于外部电路的设置。其中一种情况，电极对3的正电极和负电极平行设置。该种情况下，连接管段的结构更加的规则，进而便于制备。
实施例五
和实施例一相同之处，实施例五当中不再赘述。和实施例一不同之处在于，本实施例五当中，为了使得向安装管道9当中通入水流时，连接管段902当中的流速大于进水管段901的流速，将进水管段901设置成曲线管段，请参见图9。进而，即使水流当中携带少量杂质或者滋生了少量有机物，杂质或者有机会也只会在进水管段当中就截止，进而避免水流经过连接管段时，有机物在水质检测探头处沉积。并且，由于进水管段设计成曲线管段，进而连接管段当中流速会大于进水管段当中的流速，使得水流冲刷水质检测探头，进一步避免有机物在水质检测探头处沉积。
实施例六
和实施例五相同之处，实施例六当中不再赘述。和实施例五不同之处在于，本实施例六当中，请参见图10，电极对3设置在连接管段的同一侧。该种情况下，正电极和负电极从同一侧接入外部电路，进而可以便于外部电路的设置。其中一种情况，电极对3的正电极和负电极平行设置。该种情况下，连接管段的结构更加的规则，进而便于制备。
当然，当水质检测探头为电极对3时，电极对3的具体设置方式不受实施例一至实施例六的限制，只要电极对3的设置能够满足对水质检测的需求即可。
此外，除了采用电极对3的形式，水质检测探头还可以采用任何现有技术公开的形式。例如，水质检测探头还可以采用激光光源和接收屏的形式。其中，通过激光光源和接收屏可以检测水中悬浮物的含量情况。或者，水质检测探头还可以采用磁敏探头、热敏探头或者任何现有技术中已经公开的探头形式。
并且，本申请的安装管道9的结构不受以上实施例当中举例的限制，只要进水管段和连接管段之间满足“向安装管道9当中通入水流时，连接管段当中的流速大于进水管段的流速”即可，具体的结构形式不受上述举例限制。
根据本申请的又一个实施例，还提供一种制冷设备，包括上述供水系统。
上文提到的制冷设备可以但是不必须为冰箱。
其中，当制冷设备为冰箱，供水系统为冰箱供水系统的时候，冰箱供水系统的水容器可以设置在冰箱的间室当中，最好是冷藏间室，进而可以在夏天的时候提供冰爽的饮用水。
进一步的，以上制冷设备还包括取水开关、清洗开关和检测开关当中的至少其中之一，所述取水开关、清洗开关和检测开关当中的至少其中之一用于向所述控制器发出信号，所述控制器基于所述信号获取所述水质检测装置检测的水质参数。
以上实施方式仅用于说明本申请，而非对本申请的限制。尽管参照实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，对本申请的技术方案进行各种组合、修改或者等同替换，都不脱离本申请技术方案的精神和范围，均应涵盖在本申请的权利要求范围当中。
工业实用性
本申请涉及供水系统水质监控方法、供水系统及制冷设备，其中供水系统水质监控方法可实时监控出水管当中的水质参数，超标时控 制排出供水系统当中的水，避免有机物滋生和沉淀。且该供水系统水质监控方法可避免供水系统长时间不用后的排水冲洗，降低了操作难度，提高了用户使用的便利性。
