为了解决现有的上述热水器在将在补水后的保温水箱中的水加热到用户设定的温度过程中，保温水箱中的水温不能满足用户的使用要求，影响用户的正常使用的问题，本实施例提供了一种热水机组及其控制方法。
首先，本实施例提供的一种热水机组如图1所示，该热水机组包括加热主机1、承压水箱2、保温水箱3和混水阀9；承压水箱2的进水口(图1中承压水箱2连接有第三通断阀21的一端)用于接入自来水，保温水箱3的排水口(图1中保温水箱3连接有第三止回阀34的一端)用于供给生活用水；承压水箱2的出水口与混水阀9的第一进口连接，保温水箱3的出水口与混水阀9的第二进口连接，混水阀9的出口与加热主机1的进水口连接；加热主机1的出水口通过阀门(如1中为三通阀8)与承压水箱2的回水口、保温水箱3的回水口连接。
示例性的，本实施例的图1中是以加热主机1的出水口的阀门为三通阀8，且加热主机1的出水口通过三通阀8与承压水箱2的回水口、保温水箱3的回水口连接为例进行说明的。其中，三通阀8主要用于根据不同情况选择性地将加热主机1的出水口排出的水接入承压水箱2或保温水箱3中；作为实现该目的的上述阀门的另一种实施方式，该阀门可以包括第四通断阀(图中未示出)和第五通断阀(图中未示出)，具体地在加热主机1的出水口与承压水箱2的回水口之间设置有第四通断阀、加热主机1的出水口与保温水箱3的回水口之间设置有第五通断阀。
本实施例中混水阀9除了选择性地将承压水箱2的出水口和保温水箱3的出水口排出的水接入加热主机1的进水口之外，还需要起到将由承压水箱2和保温水箱3的水混合到要求的温度的作用，目前混水阀9包括手动机械调节式和电动温控阀。同时混水阀9由于调节过程中其内部水流截面的改变，还能起到调节流量的作用。所以，混水阀9还可以实现仅允许承压水箱2的水通过并对其流量进行调节，也实现可以仅允许保温水箱3的水通过并对其流量进行调节。其中，混水阀9的具体结构属于现有技术，故在此不对该混水阀9的具体结构进行说明，但是本领域技术人员在实施本发明的热水机组的过程中，可以参照中国专利申请文件CN105626903A、CN205780896U、CN208651635U等公开的电动温控阀，以及市场上现有的混水阀9并根据实际需要进行选择使用。
在本发明提供的上述热水机组中，热水过程中通过混水阀9来调节承压水箱2与保温水箱3进入加热主机1的热水的流量比例，以实现调配后的水经加热主机1一次加热后直接进入保温水箱3以始终保证满足用户的使用需求；同时，在混水阀9动态调节过程中可以通过与加热主机1的出水口连接的阀门将热水主机的出水口流出的不满足温度要求的水回流至承压水箱2中，避免了不满足温度要求的水流入保温水箱3。
本实施例中的加热主机1可以选择为热泵主机，热泵主机包括加热水腔以及用于对加热水腔中的水进行加热的第一换热器；第一换热器通过冷媒管路与电子膨胀阀、压缩机和第二换热器连接并形成冷媒循环回路；加热主机1的出水口和进水口与加热水腔连通。可以理解的是，该热泵主机的加热水腔可以形成于具有一定长度的盘管内，从而能使获得加热效果水流路线延长，第一换热器可以设置为与加热水腔的延伸路线并行的盘管式。从而有足够的时间对流动中的水流进行加热，且当加热水腔形成于盘管内时，单位体积的水与第一换热器的接触面积较大，更利于第一换热器与水流之间进行热交换。
在热水时第一换热器作冷凝器使用且第二换热器作蒸发器使用，在极低外界环境下热水时，第二换热器的表面会结霜，导致热水效果降低。而在除霜时，需要将第一换热器作蒸发器使用且第二换热器作冷凝器使用，以利用第二换热器释放的热量来进行化霜。
在本实施例提供的上述热水机组中，当加热主机1为热泵主机时，在对与热泵主机通过冷媒循环管路连接的位于室外的第二换热器进行除霜的过程中，可以通过调节三通阀8将热泵主机的出水口与承压水箱2的回水口之间导通，且通过混水阀9将热泵主机的进水口与承压水箱2的出水口之间导通，以使热泵主机与承压水箱2之间形成水循环。如此，与第一换热器进行热交换的水量较多而有利于改善第一换热器的吸热效果，进而提高了第二换热器的除霜效果。
作为本实施例提供的上述热水机组的一种优选的实施方式，热水机组还包括水位检测器31、第一温度传感器32、第二温度传感器11、第三温度传感器12、第一通断阀6、第二通断阀5、第三通断阀21、第一水泵91和第二水泵33中的至少一个；其中，水位检测器31设置于保温水箱3中，用于检测保温水箱3的水位；第一温度传感器32设置于保温水箱3 中，用于检测保温水箱3中的水温；第二温度传感器11设置于加热主机1的进水口侧；第三温度传感器12设置于加热主机1的出水口侧；第一通断阀6设置于承压水箱2的出水口与混水阀9之间；第二通断阀5设置于三通阀8与保温水箱3的回水口之间；第三通断阀21设置于承压水箱2的进水口侧；第一水泵91设置于加热主机1与混水阀9之间，当需要加热水时可以为承压水箱2和保温水箱3中的水进入加热主机1中提供动力；第二水泵33设置于保温水箱3的排水口侧，为生活用水提供动力。其中，本实施例中的第一通断阀6、第二通断阀5和第三通断阀21可以选择为电磁阀和电动阀，以便于热水机组的自动控制。
作为本实施例提供的上述热水机组的一种优选的实施方式，热水机组还包括控制器；控制器的信号输入端与水位检测器31、第一温度传感器32、第二温度传感器11和第三温度传感器12中的至少一个通信连接；控制器的信号输出端与混水阀9、三通阀8、第一通断阀6、第二通断阀5、第三通断阀21、第一水泵91和第二水泵33中的至少一个通信连接。
示例性地，当用户对保温水箱3中的热水进行使用后，水位检测器31能检测到保温水箱3的水位下降，则立即启动加热主机1，通过混水阀9来调节承压水箱2与保温水箱3进入加热主机1的热水的流量比例，同时根据第二温度传感器11检测的加热主机1的进水口侧的水温，或者根据第三温度传感器12检测的加热主机1的出水口侧的水温，以实现调配后的水经加热主机1一次加热后进入保温水箱3能始终保证满足用户的使用需求。
此外，当保温水箱3中的水位没有下降但保温水箱3中的水温降低到用户需求的水温范围以下时，则即时通过三通阀8将加热主机1的出水口与保温水箱3的回水口连通，通过混水阀9将加热主机1的进水口与保温水箱3的出水口连通，同时启动加热主机1，通过循环加热的方式来提高保温水箱3中的水温。
为了保证生活用水的干净卫生，可以在承压水箱2的进水口侧连接有第一净水装置22；此外，为了防止保温水箱3、加热主机1及水流管路中积累太多的水垢，还可以在加热主机1的进水口与混水阀9之间连接有第二净水装置92。其中，第一净水装置22和第二净水装置92为电子除垢仪或过滤器，第一净水装置22可以优选为过滤器，第二净水装置 92可以优选为电子除垢仪。
进一步地，为了防止由于水压异常等原因导致水倒流影响热水机组的正常使用，该热水机组中还设置有第一止回阀23、第二止回阀7和第三止回阀34中的至少一个；第一止回阀23设置在承压水箱2的进水口侧，以防止承压水箱2中的水向外倒流；第二止回阀7设置在承压水箱2的出水口与混水阀9之间，以防止水倒流回承压水箱2；第三止回阀34设置在生活热水箱的排水口侧，以防止水倒流回保温水箱3。
作为本实施例提供的上述热水机组的一种优选的实施方式，承压水箱2的下部的水压较大，可以将承压水箱2的出水口设置于承压水箱2的下部，以利于承压水箱2的水排出；类似的，还可以将保温水箱3的出水口和/或排水口设置于保温水箱3的下部。此外，当热水机组的热水用于供给暖气等需要反复循环利用热水的设备时，保温水箱3还设置有用于与生活回水管4连接的进水口。
然后，本实施例还提供了一种热水机组的控制方法，如图1所示，该热水机组包括加热主机1、承压水箱2、保温水箱3和混水阀9；承压水箱2的进水口用于接入自来水，保温水箱3的排水口用于供给生活用水；承压水箱2的出水口与混水阀9的第一进口连接，保温水箱3的出水口与混水阀9的第二进口连接，混水阀9的出口与加热主机1的进水口连接；加热主机1的出水口通过阀门与承压水箱2的回水口、保温水箱3的回水口连接，如图2所示，该控制方法包括：
S1、获取加热主机1的出水口的出水温度、保温水箱3的实际水温和实际水位；
S2、将出水温度、实际水温分别与用户设定水温进行比较；
S3、将实际水位与预设的循环制热水位和溢流水位进行比较；
S4、基于比较结果控制加热主机1、混水阀9和阀门。
根据本实施例的热水机组的控制方法，通过将加热主机1的出水口的出水温度、保温水箱3的实际水温分别与用户设定水温进行比较，并将保温水箱3的实际水位与预设的循环制热水位和溢流水位进行比较，然后基于比较结果控制加热主机1、混水阀9和阀门。使得可以根据获取的具体信息来实现热水机组的自动控制，并且保证当保温水箱3的实际水位大于循环制热水位且小于溢流水位，且实际水温与用户设定水温的差 值小于或等于预设的允许温差时，可以通过混水阀9来调节承压水箱2与保温水箱3进入加热主机1的水流量比例，使得调配后的水经加热主机1一次加热后直接进入保温水箱3并能始终保证满足用户的使用需求。
本实施例结合图1中的三通阀8作为阀门进行说明，加热主机1的出水口的出水温度可以通过第三温度传感器12进行实施监测，保温水箱3的实际水温可以通过第一温度传感器32进行实施监测，保温水箱3的实际水位可以通过水位检测器31进行实施监测。
需要说明的是，尽管上文详细描述了本发明的热水机组的控制方法的详细步骤，但是，在不偏离本发明的基本原理的前提下，本领域技术人员可以对上述步骤进行组合、拆分及调换顺序，如此修改后的技术方案并没有改变本发明的基本构思，因此也落入本发明的保护范围之内。例如，步骤S2与步骤S3可以同时执行，也可以按照任意顺序先后执行。
作为本实施例提供的上述控制方法的一种优选的实施方式，步骤S4中基于比较结果控制加热主机1、混水阀9和阀门的步骤包括：若实际水位大于循环制热水位且小于溢流水位，且实际水温与用户设定水温的差值小于或等于预设的允许温差；则启动加热主机1进行加热，并根据出水温度与用户设定水温的比较结果控制混水阀9以将出水温度调节至用户设定水温，同时根据出水温度与用户设定水温的比较结果控制阀门选择性地将加热主机1的出水口与承压水箱2的回水口或保温水箱3的回水口导通。
本领域技术人员可以理解的是，将出水温度调节至用户设定水温，在具体实施时，可以将控制程序实际设定为将出水温度调节至以用户设定水温为准的一定范围内，如用户设定温度为60℃时，其调节温度可以设置为59℃～61℃。如此设置，在实际中一般均能满足用户的实际需求，其仍应落入本发明的保护范围之内。预设的允许温差可以根据实际需求以及温度传感器的精度等条件进行设定，例如，预设的允许温差可以为2℃～3℃中的任何值。
具体地，根据出水温度与用户设定水温的比较结果控制混水阀9以将出水温度调节至用户设定水温的步骤包括：若出水温度小于用户设定水温，则通过混水阀9减小承压水箱2的出水口的流量并且/或者增大 保温水箱3的出水口的流量，以将出水温度增大至用户设定水温。此外，若出水温度大于用户设定水温，则通过混水阀9增大承压水箱2的出水口的流量并且/或者减小保温水箱3的出水口的流量，以将出水温度减小至用户设定水温。
同时，根据出水温度与用户设定水温的比较结果控制阀门选择性地将加热主机1的出水口与承压水箱2的回水口或保温水箱3的回水口导通的步骤包括：若出水温度小于用户设定水温，则通过阀门将加热主机1的出水口与承压水箱2的回水口导通；并且/或者若出水温度大于或等于用户设定水温，则通过阀门将加热主机1的出水口与保温水箱3的回水口导通。
根据本发明的热水机组的控制方法，在混水阀9动态调节过程中，若出水温度小于用户设定水温，则通过阀门将加热主机1的出水口与承压水箱2的回水口导通，以将热水主机的出水口流出的不满足用户设定水温要求的水回流至承压水箱2中，避免了不满足温度要求的水流入保温水箱3。从而，进一步地保证了在补水时保温水箱3中的水温能始终满足用户的使用要求，以提高用户的使用体验。
作为本实施例提供的上述控制方法的一种优选的实施方式，步骤S4中基于比较结果控制加热主机1、混水阀9和阀门的步骤包括：若实际水位小于循环制热水位，则启动加热主机1进行加热，并控制混水阀9仅允许承压水箱2的出水口与加热主机1的进水口导通，且控制阀门仅允许加热主机1的出水口与保温水箱3的回水口导通。
当保温水箱3中实际水位小于循环制热水位时，则保温水箱3中的热水量偏低，为了兼顾补水和热水效率，可以通过上述方法将承压水箱2中的水经加热主机1一次加热后直接进入保温水箱3。如果经一次加热后没有达到用户设定水温的要求，则可以使用以下的循环加热方法，通过加热主机1对保温水箱3中的水进行循环加热至用户设定水温。同时，当保温水箱3中的热水自然冷却到用户设定水温以下时，也可以采用循环加热的方法。
作为本实施例提供的上述控制方法的一种优选的实施方式，步骤S4中基于比较结果控制加热主机1、混水阀9和阀门的步骤包括：若实际水位大于循环制热水位，且实际水温与用户设定水温的差值大于预 设的允许温差，则启动加热主机1进行加热，并控制混水阀9仅允许保温水箱3的出水口与加热主机1的进水口导通，且控制阀门仅允许加热主机1的出水口与保温水箱3的回水口导通。即通过循环加热的方式将保温水箱3中的热水加热至用户设定水温。
作为本实施例提供的上述控制方法的一种优选的实施方式，加热主机1为热泵主机，在步骤S4中基于比较结果控制加热主机1、混水阀9和阀门的步骤之前该控制方法还包括：获取加热主机1的进水口的进水温度；计算出水温度与进水温度的实际温差；将实际温差与预设的第一温差值进行比较；当实际温差小于第一温差值时，控制热泵主机进入除霜模式，控制阀门仅允许加热主机1的出水口与承压水箱2的回水口导通，并控制混水阀9将承压水箱2的出水口与加热主机1的进水口导通。
示例性地，加热主机1的进水口的进水温度可以通过第二温度传感器11进行实时监测。第一温差值可以用于衡量加热主机1的加热效果，当出水温度与进水温度的实际温差小于第一温差值时，说明加热主机1的加热效果较低，不能正常的对保温水箱3中的水进行加热，而在冬季加热主机1为热泵主机时，往往是由于与热泵主机的室外的第二换热器结霜所致。此时，控制热泵主机进入除霜模式，即将第一换热器作蒸发器使用且第二换热器作冷凝器使用，以利用第二换热器释放的热量来进行化霜。同时，控制阀门仅允许加热主机1的出水口与承压水箱2的回水口导通，并控制混水阀9将承压水箱2的出水口与加热主机1的进水口导通，以使得加热主机1与承压水箱2之间形成水循环。如此，与第一换热器进行热交换的水量较多而有利于改善第一换热器的吸热效果，进而提高了室外换热器的除霜效果。
作为本实施例提供的上述控制方法的一种优选的实施方式，当控制热泵主机进入除霜模式后，在控制混水阀9将承压水箱2的出水口与加热主机1的进水口导通时，该控制方法还包括：将实际温差与预设的第二温差值进行比较；当实际温差小于第二温差值时，则通过混水阀9减小承压水箱2的出水口的流量并且/或者增大保温水箱3的出水口的流量，以使实际温差大于或等于第二温差值。
示例性地，特殊情形下，加热主机1在进行除霜时，加热主机1的进水口的水温大于出水口的水温，第二温差值用于衡量加热主机1 的除霜效果，当出水温度与进水温度的实际温差小于第二温差值时，说明加热主机1的除霜效果较低，承压水箱2中的水温不能满足加热主机1正常的除霜需求，此时混水阀9可以控制保温水箱3中的部分热水与承压水箱2的冷水混合后流入加热主机1，以提高加热主机1的除霜效果。
作为本实施例提供的上述控制方法的一种优选的实施方式，混水阀9与加热主机1的进水口之间设置有第一水泵91，当需要加热水时可以为承压水箱2或保温水箱3中的水进入加热主机1中提供动力；所以可以在控制混水阀9将加热主机1的进水口与承压水箱2的出水口和/或保温水箱3的出水口导通的同时启动第一水泵91。
作为本实施例提供的上述控制方法的一种优选的实施方式，承压水箱2的出水口与混水阀9之间设置有第一通断阀6，控制混水阀9将加热主机1的进水口与承压水箱2的出水口导通的同时打开第一通断阀6；保温水箱3的回水口上连接有第二通断阀5，控制阀门将加热主机1的出水口与保温水箱3的回水口导通的同时打开第二通断阀5。当本实施例的热水机组不需要加热保温水箱3中的热水时，可以将第一通断阀6、第二通断阀5关闭，来阻断热水机组中水的流动，从而实现对本实施例提供的前述热水机组的可靠控制。
当然，上述可以替换的实施方式之间、以及可以替换的实施方式和优选的实施方式之间还可以交叉配合使用，从而组合出新的实施方式以适用于更加具体的应用场景。
本领域的技术人员应当理解的是，可以将本实施例提供的热水机组的控制方法作为程序存储在一个计算机可读取存储介质中。该存储介质中包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)或处理器(processor)执行本发明各个实施例方法的部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
此外，本领域的技术人员能够理解，尽管在此的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的保护范围之内并且形成不同的实施例。 例如，在本发明的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
