请参阅图1和图2，在某些实施方式中，热水器100还包括加热件70，加热件70安装在安装件40上并位于内胆10中。在某些实施方式中，热水器100还包括测温件71，测温件71安装在安装件40上并位于内胆10中。如此，热水器100可通过位于内胆10中的加热件70对内胆10中储存的水进行加热，还可通过位于内胆10中的测温件71对内胆10中储存的水温进行监测，进而可以实现热水器100调节水温、节能等功能。
具体地，热水器100的加热件70可以连接在安装件40上，加热件70位于安装件40上靠近镁棒20和电子阳极30的位置，加热件70通电后可实现对内胆10内的水加热，加热件70可以是不锈钢或铜材料的加热管，进一步地，加热管的形式还可以是单管加热管、双管加热管或旋涡式加热管等。测温件71可以是具有温度传感器的金属元件，测温件71可与加热件70安装在安装件40上的位置相接近，可便于测量内胆10核心的水温。
请参阅3-图5，在某些实施方式中，热水器100包括多个开关90和电控模块80，开关90与电子阳极30一一对应，电控模块80用于控制至少一个开关90切换位置，以使同一个内胆10中的电子阳极30和镁棒20中的其中一个与内胆10电连接。
如此，热水器100可以通过电控模块80控制开关90，在不同情况下可采用牺牲阳极或电子阳极30对内胆10进行腐蚀防护，实现减小牺牲阳极损耗，延长内胆10使用寿命，降低水质污染的目的。
具体地，热水器100可以是双胆热水器100，双胆热水器100可具有两个内胆10，当热水器100是双胆热水器100时，热水器100的电控模块80可以是一个，一个电控模块80可以控制开关90，开关90的数量可以是两个，即一个电控模块80可以控制两个开关90，两个开关90的一个开关90可控制双胆热水器100中一个内胆10与该内胆10中的镁棒20和电子阳极30电连接，类似的，两开关90中的另一开关90可控制双胆热水器100中另一内胆10与该内胆10中的镁棒20和电子阳极30电连接。
请参阅图3-图5，在某些实施方式中，在电子阳极30与对应的内胆10电连接的情况 下，电控模块80用于通过电子阳极30检测内胆10中的电位值，并根据电位值向电子阳极30施加预定电压，电位值与预定电压反相关关系。
如此，电控模块80根据测量的内胆10中的电位值的高低对电子阳极30施加的预定电压进行调整输出，实现将内胆10的电位值稳定在停止腐蚀水平，从而保护内胆10稳定不受腐蚀，同时可防止对电子阳极30施加不当的预定电压，进而提升电子阳极30和内胆10的使用寿命。
具体地，在某一实施例中(如图4所示)，热水器100可以是立置的双胆热水器100，当使用立置双胆热水器100时，两个内胆10竖置并排安装，底部可由连接管12进行连通。内胆10的一端可安装有电子阳极30及镁棒20，另一内胆10的一端也可安装有电子阳极30及镁棒20。内胆10、电子阳极30与镁棒20可均通过连接线81与电控模块80电性的相连。
在另一实施例中(如图5所示)，热水器100可以是卧置的双胆热水器100，当使用卧置双胆热水器100时，上下两个内胆10水平并排安装，中部由两个连接管12进行连通。内胆10的一端可安装有电子阳极30及镁棒20，另一内胆10的一端也可安装有电子阳极30，下部安装有镁棒20。内胆10、电子阳极30与镁棒20可均通过连接线81与电控模块80电性的相连。
两内胆10均注满水后，可向电控模块80输入电压，输入电压的数值可以是3V至10V，电控模块80可启动，电控模块80可通过控制继电器将内胆10与电子阳极30连通，将内胆10与电子阳极30连通，并输出预定电压，输出预定电压的数值可以是0.2V至8V，向电子阳极30和内胆10施加槽压，并分别向两个内胆10提供阴极极化电流，电控模块80根据测量的电位值调整对电子阳极30的输出电压，分别使两个内胆10的电位值稳定在停止腐蚀水平。
电位值与预定电压呈反相关关系。可以理解，例如，电控模块80测量的内胆10的电位值处于900mV时为稳定的停止腐蚀水平，当电控模块80测量的内胆10的电位值小于900mV时，内胆10可处于腐蚀，电控模块80可调整对电子阳极30输入的预定电压，例如可以是由500mV提升至1000mV，由此，电子阳极30可提高输出使内胆10的电位值升高至900mV，内胆10可处于稳定停止腐蚀水平。类似的，当电控模块80测量的内胆10的电位值大于900mV时，内胆10可处于腐蚀，电控模块80可调整对电子阳极30输入的预定电压，例如可以是由1000mV降低至500mV，由此，电子阳极30可降低输出使内胆10的电位值下降至900mV，内胆10可处于稳定停止腐蚀水平。
请参阅图3-图5，在某些实施方式中，电控模块80还用于在电位值异常的情况下，控制开关90切换位置以断开电子阳极30与内胆10的电连接，并使镁棒20与对应的内胆10 电连接；和/或，
停止向电子阳极30施加电压；和/或，
发出对应的内胆10的报警信号。
如此，热水器100通过电控模块80对电位值异常的检测，可在热水器100断电、电子阳极30发生故障等情况下控制开关90断开电子阳极30与内胆10的电连接，采用镁棒20对内胆10进行腐蚀防护并发出报警信号，可以实现减小镁棒20损耗，延长内胆10使用寿命，降低水质污染的目的。电控模块80还可发出报警信号，提升热水器100使用过程的安全性。
具体地，电控模块80检测到其中一个内胆10的电位值处于故障状态时，可立刻停止对该内胆10内的电子阳极30输出预定电压，然后可执行针对该内胆10和电子阳极30组件的故障进行处理，可断开电子阳极30与该内胆10的连接，并连接镁棒20与该内胆10，采用镁棒20对该内胆10进行腐蚀防护，与此同时，电控模块80还可同步的单独发出警报信号。可以理解，在另一内胆10与另一内胆10中的电子阳极30不受影响，电子阳极30持续保护另一内胆10。
如电控模块80断电或检测到两个内胆10电位均处于故障状态，将断开两个电子阳极30与两个内胆10的连接，并使两个内胆10分别连接对应的镁棒20，对两个内胆10持续的保护。
示例性地，当内胆10的电位值超过1200mV为处于故障状态时，电控模块80检测到内胆10的电位值的超过1200mV时，电控装置可将对该内胆10内的电子阳极30输出预定电压降至零并将发出警报信号，电控装置还可控制开关90断开电子阳极30与该内胆10的连接。
请参阅图3-图5，在某些实施方式中，电控模块80用于每隔预定时长检测一次内胆10中的电位值，并在电位值大于阈值的情况下，减小向电子阳极30的施加电压的时长；在电位值小于阈值的情况下，增大向电子阳极30的施加电压的时长，向电子阳极30施加电压的时长与预定时长相等。
如此，电控模块80根据预定时常内对内胆10检测的电位值的相比阈值的大小，进一步的对电子阳极30施加的电压的时长进行调整，实现将内胆10的电位值稳定在停止腐蚀水平，从而保护内胆10稳定不受腐蚀，同时可防止对电子阳极30施加不正常的电压时长，进而影响电子阳极30和内胆10的使用寿命。
具体地，当两内胆10均注满水后，电控模块80可在预定时长检测内胆10的电位值，例如，电位值的阈值可为900mV，电控模块80对电子阳极30施加固定为1000mV的电压时长时为5分钟时可保持内胆10的电位值稳定在阈值。当电控模块80在5分钟内检测出 内胆10的电位值为1200mV时，内胆10的电位值大于阈值，电控模块80可保持固定1000mV的电压对电子阳极30施加少于5分钟的电压时长，可使内胆10的电位值降低至900mV的阈值状态。类似的，当电控模块80在5分钟内检测出内胆10的电位值为700mV时，内胆10的电位值小于阈值，电控模块80可保持固定1000mV的电压对电子阳极30施加大于5分钟的电压时长，可使内胆10的电位值提升至900mV的阈值状态。
请参阅图6，本申请实施方式的热水器100的控制方法中热水器100包括多个内胆10和多个电子阳极30，多个内胆10相互连通，每个内胆10中设置有至少一个电子阳极30，控制方法包括：
S1：在电子阳极30与对应的内胆10电连接的情况下，通过电子阳极30检测内胆10中的电位值；
S2：根据电位值向电子阳极30施加预定电压，电位值与预定电压反相关关系。
本申请实施方式的热水器100的控制方法可根据测量的内胆10中的电位值的高低对电子阳极30施加的预定电压进行调整输出，实现将内胆10的电位值稳定在停止腐蚀水平，从而保护内胆10稳定不受腐蚀，同时可防止对电子阳极30施加不当预定电压，进而影响电子阳极30和内胆10的使用寿命。
具体地，电子阳极30与内胆10相电连接，然后再通过电子阳极30检测内胆10的电位值，再通过判断电位值相对于设定值的高低，进一步再对电子阳极30施加的预定电压调节，当电位值相比预定值高时，预定电压降低，当电位值相比预定值低时，预定电压升高，电位值与预定电压反相关关系。
请参阅图7，在某些实施方式中，控制方法还包括：
S3：在电位值异常的情况下，控制开关90切换位置以断开电子阳极30与内胆10的电连接，并使镁棒20与对应的内胆10电连接；和/或，
S4：停止向电子阳极30施加电压；和/或，
S5：发出对应的内胆10的报警信号。
如此，热水器100通过电控模块80对电位值异常的检测，可在热水器100断电、电子阳极30发生故障等情况下控制开关90断开电子阳极30与内胆10的电连接，采用镁棒20对内胆10进行腐蚀防护并发出报警信号，可以实现减小镁棒20损耗，延长内胆10使用寿命，降低水质污染的目的。电控模块80还可发出报警信号，提升热水器100使用过程的安全性。
具体地，在步骤(S1和S2)通过电子阳极30检测内胆10的电位值之后，可进一步的判断电位值是否处于异常状态，然后可同步的通过控制切换开关90的位置来断开电子阳极30与内胆10的电连接并切换为镁棒20同对应的内胆10相连接，然后可停止向电子阳极 30施加预定电压，然后可向对应的内胆10发出警报信号。
进一步地，可以理解，当电控模块检测并判断电位值处于异常状态后，步骤S3、步骤S4和步骤S5可执行其中一个、其中两个或全部执行。例如，内胆10的异常电位值为大于2000mV，当电控模块80检测到内胆10的电位值为2500mV时，可执行步骤S3、步骤S4和步骤S5其中的一个，即电控模块80可控制控制开关90断开电子阳极30与内胆10的电连接并切换为镁棒20同对应的内胆10相连接或者停止向电子阳极30施加预定电压或者向对应的内胆10发出警报信号。
类似的，还可执行步骤S3、步骤S4和步骤S5其中的两个，即电控模块80可控制控制开关90断开电子阳极30与内胆10的电连接并切换为镁棒20同对应的内胆10相连接同时停止向电子阳极30施加预定电压；或者，电控模块80可控制控制开关90断开电子阳极30与内胆10的电连接并切换为镁棒20同对应的内胆10相连接同时向对应的内胆10发出警报信号；或者，电控模块80停止向电子阳极30施加预定电压同时向对应的内胆10发出警报信号。
类似的，还可执行步骤S3、步骤S4和步骤S5中的全部步骤，即电控模块80可控制控制开关90断开电子阳极30与内胆10的电连接并切换为镁棒20同对应的内胆10相连接并且停止向电子阳极30施加预定电压并且向对应的内胆10发出警报信号。
请参阅图8，在某些实施方式中，控制方法还包括：
S6：每隔预定时长检测一次内胆10中的电位值；
S7：在电位值大于阈值的情况下，减小向电子阳极30的施加电压的时长向电子阳极30施加电压的时长与预定时长相等；在电位值小于阈值的情况下，增大向电子阳极30的施加电压的时长，向电子阳极30施加电压的时长与预定时长相等。
如此，电子阳极30作为参比电极，以预定时长为间隔测量内胆10的实时电位，将内胆10电位测量值与阈值比对后，即时调整向电子阳极30的施加电压的时长后，使内胆10电位处于停止腐蚀的水平，通过不断循环上述步骤，可以动态的调整内胆10电位并使其始终维持在保护电位范围内。若出现故障，可识别后进入故障模式，并通过故障处置采用备用装置对内但进行保护，使内胆10在各种情况下均能得到保护，且多个电子阳极30的工作过程相互独立，互不干扰，可同时分别对多个内胆10进行保护。
具体地，可先在一定的预定时长内检测一次内胆10中的电位值，然后可在电位值大于阈值的情况下，减小向电子阳极30的施加电压的时长，同步的，当电位值小于阈值的情况下，可增大向电子阳极30的施加电压的时长，此时，向电子阳极30施加电压的时长与预定时长相等。
在某一实施例中(如图9所示并参考图3-图5)，在电子阳极30与对应的内胆10电连 接的情况下，电子阳极30运行启动模式，通过电控装置80向内胆10和电子阳极30执行预定时长的通断电并检测内胆10中的电位值，运行预定时长的检测周期Tj后，在Tj时刻检测电位值Ut。判断此时Ut是否为故障状态，若故障，则直接进行故障处置，故障处置可采用步骤S3、步骤S4和步骤S5中的一个或多个执行方式，例如，控制开关90可断开电子阳极30与内胆10的电连接，可采用镁棒20对内胆10进行腐蚀防护，可发出报警信号等故障处理方式。然后可采用备用装置对内胆10进行保护，备用装置可以是采用备用的镁棒或电子阳极替代故障装置等处置方式；若正常，则进入调整模式。
调整模式下采用此前的预定时长的通断电时间运行，运行一个Tj后检测此时内胆10的电位值U1，检测Ut是否处于故障状态，若故障，则进入故障处置，采用备用装置对内胆10进行保护；若正常，则将U1与阈值U0进行比对，若U1大于U0，则减小向电子阳极30施加电压的时长；若U1小于U0，则增大向电子阳极30施加电压的时长。在下一周期开始执行新的预定时长的通断。在运行了一个Tj后再次检测内胆10的电位值U1，并进行故障判断识别与通电时长调整。依此循环，实现对内胆10的保护。
另一电子阳极30采用与上述电子阳极30相同的控制方法，同时工作，并独立地对另一内胆10进行保护。
在另一实施例中(如图10所示并参考图3-图5)，在电子阳极30与对应的内胆10电连接的情况下，可以通过电控装置80向内胆10和电子阳极30执行预定时长的通断电并检测内胆10中的电位值。电子阳极30运行启动模式A，启动模式A可以是电控模块执行的预定时长的通断相比图9实施例中的启动模式的预定时长的通断短。运行一个预定时长TA后，转为运行启动模式B，启动模式B可以是电控模块执行的预定时长的通断相比图9实施例中的启动模式的预定时长的通断。再运行一个预定时长TB后进入调整模式。在运行启动模式A至启动模式B之间的阶段不作故障判断识别与处理。
调整模式下采用此前的预定时长的通断电时间运行，运行一个电位值检测周期Tj后检测此时内胆10的电位值U1，检测Ut是否处于故障状态，若故障，则进入故障处置，故障处置可采用步骤S3、步骤S4和步骤S5中的一个或多个执行方式，例如，控制开关90可断开电子阳极30与内胆10的电连接，可采用镁棒20对内胆10进行腐蚀防护，可发出报警信号等故障处理方式。采用备用装置对内胆10进行保护，备用装置可以是采用备用的镁棒或电子阳极替代故障装置等处置方式；若正常，则将U1与阈值U0进行比对，若U1大于U0，则减小对电子阳极30施加电压的时长；若U1小于U0，则增大对电子阳极30施加电压的时长。在下一周期开始执行新的预定时长的通断电。在运行了一个Tj后再次检测内胆10的电位值U1，并进行故障判断识别与通电时长的调整。依此循环，实现对内胆10的保护。
另一电子阳极30采用与上述电子阳极30相同的控制方法，同时工作，并独立地对另一内胆10进行保护。
