与现有技术相比，本发明的优点和积极效果是：通过在混水机构中增加调温模块，调温模块能够根据混水机构的出水温度来自动的调节冷水和热水的混合量，这样，便可以无需人工调节冷热水的混合量，实现自动调节冷水和热水的混合量，进而提高了电热水器的使用可靠性和安全性。与此同时，对于进水三通而言，其满足电热水器自身正常进水要求外，还可以根据需要向混水机构中输送冷水以实现冷热水的混合，使得整体结构更加的紧凑；并且，通过在进水三通和混水机构之间增加混水机构，使得用户能够根据需要来实现冷热水的混合，进而满足用户不同的用水要求，以提高用户体验性。

实施例一，如图1-图2所示，本实施例提出了一种防烫组件，本实施例提出了一种防烫组件，防烫组件用于安装在电热水器中水箱上，水箱输出的热水经由防烫组件处理，以达到防烫的目的。
其中，防烫组件，包括：
进水三通10，进水三通10具有一进口和两个出口；
混水机构20，混水机构20包括：第一管体1、第二管体2、第三管体3和调温模组4；其中，第一管体1的一端口为出水口、另一管口为安装口，第一管体1的管壁上设置有第一进水口和第二进水口，第二管体2设置在第一管体1的侧壁上并与所述第一进水口连通，第三管体3设置在第一管体1的侧壁上并与所述第二进水口连通，调温模组4设置在所述安装口中并用于依靠所述出水口的出水温度变化来控制所述第二进水口选择性连通所述冷水腔体；
截止阀30，截止阀30连接在其中一所述出口和第三管体3之间。
在实际组装时，进水三通10的一出口与电热水器中水箱的进水管连接，而进水三通10的进口则连接自来水管，第二管体2则与水箱的出水管连接，而第一管体1的出水口则与用水终端连接。
本实施例中的第一管体1中设置有调温模组4，以通过调温模组4来自动调节出水口11的出水温度，进而避免从出水口11输出的热水温度过高而烫伤用户。
在实际使用时，则第二管体2用于输入热水，而第三管体3用于输入冷水。热水进入到第一管体1中并经由出水口11输出，而对于第三管体3中的冷水则由调温模组4来控制冷水的进入量。
具体为，水箱中的水被加热到设定的温度，而用户用水温度低于水箱中的水温，则从水箱中输出的热水经由第二管体2进入到第一管体1后，调温模组4能够根据第一管体1出水口的出水温度自动调节第三管体3的冷水混合量，以使得第一管体1输出用户所需的水温。
这样，便无需用户通过混水阀手动调节，同时，也无需用户自己用手来测试水温，以提高用户体验性和使用安全性，减少烫伤用户的现象发生。
而通过配置截止阀30，则使得用户可以根据需要自己控制是否需要进行冷热水混合，进而满足用户对高温水的输出使用要求，以提高用户使用体验性。
在一些实施例中，截止阀30可以为手动阀门，或者，截止阀30为电控阀门。在此，对于截止阀30的具体表现实体不做限制和赘述。
实施例二，如图3-图9所示，混水机构20的具体机械自动调温方式，则主要通过调温模组4来实现，调温模组4的具体结构包括：柱塞41、密封堵头42和温感驱动部件43，柱塞41上设置有安装孔411和至少一个贯通孔412，贯通孔412位于安装孔411的一侧，温感驱动部件43包括缸体431和推杆432，推杆432插入到缸体431中，推杆432与缸体431内部之间形成温感腔体，所述温感腔体中填充有热胀冷缩材料（未图示），缸体431设置在安装孔411中； 其中，密封堵头42设置在安装口12上，柱塞41可滑动的设置在第一管体1中，第一管体1内部在柱塞41与密封堵头42之间形成冷水腔体，推杆432与密封堵头42相对布置；所述热胀冷缩材料用于依靠出水口11的出水温度变化来驱动推杆432移动，推杆432用于与密封堵头42配合来带动柱塞41滑动以控制第二进水口14选择性连通所述冷水腔体。
调温模组4的具体工作过程为：当出水口11的出水温度过高时，则温感驱动部件43中缸体431内的热胀冷缩材料发生膨胀并使得推杆432抵靠在密封堵头42上。推杆432利用所述热胀冷缩材料产生的力将推动缸体431带动柱塞41朝向出水口11方向移动，进而使得第一管体1上配置的第二进水口14与其内部形成的所述冷水腔体相连通。
此时，第三管体3引入的冷水并进入到所述冷水腔体中，冷水经由贯通孔412流出并与第一进水口13流入的热水进行混合，最终，降低出水口11的出水温度，进而达到防止用户被烫伤的现象发生。
而由于调温模组4依靠热胀冷缩材料根据温度变化而发生体积变化，以控制推杆432移动，进而实现控制第二进水口14选择性的与所述冷水腔体连通。
在某些实施例中，对于热胀冷缩材料的选择，则可以采用常规技术中利用石蜡来进行温度控制的方案，例如可以采用石蜡温控器中的石蜡填充材料，而有关石蜡填充料的具体的组分配比，在此不做限制。
在另一些实施例中，为了实现在设定温度范围内进行有效的温度控制，则设置调温模组4中的推杆432在初始状态下距离密封堵头42具有一定的距离，进而可以实现在某一温度区间内进行更加准确的控温。
例如：在出水口11的出水温度低于第一设定温度T1时，推杆432的自由端部与密封堵头42之间形成间隔；在出水口11的出水温度高于第二设定温度T2时，推杆432的自由端部抵靠在密封堵头42上。
具体的，T2的温度值大于T1的温度值，在第一管体1的出水口11向外输出热水的过程中，当水温低于T1的情况下，推杆432处于完全回缩的状态，而在出水口11的出水温度大于T1后，推杆432在所述热胀冷缩材料的作用下相对于缸体431逐渐向外伸出，而在出水口11的出水温度未达到T2之前，则柱塞41处于不动的状态，以保持第二进水口14与所述冷水腔体断开。这样，便可以保证用户在设定的温度范围内使用热水，进而避免在热水温度不高的情况下再加入冷水而造成用户用水温度过低。
而在实际应用过程中，有关T1和T2的取值，在此不做限制，主要根据不同情况下用户的热水使用需求所要求的温度，T2作为触发使用冷水进行混合以避免烫伤用户的温度触发值。例如：以正常家用为例，则T1可以取值为40度，而T2可以取值为50度；进入到第一管体1中的热水在50度以下的情况下，第三管体3中的冷水不会进入到第一管体1中。而在第一管体1中的水温超过50度后，为了避免热水烫伤用户，则第三管体3中输送的冷水进入到第一管体1中并与热水混合，以降低从出水口11输出的水温温度。
在另一个实施例中，为了避免第二管体2和第三管体3进入的水相互影响，则调温模组4还包括：密封圈44，密封圈44套在柱塞41上并夹在柱塞41和第一管体1的内管壁之间，密封圈44位于第一进水口13和第二进水口14之间。
具体的，在将柱塞41放入到第一管体1中后，密封圈44将紧密的贴靠在第一管体1的内管壁上，利用密封圈44将第一进水口13和第二进水口14间隔开，以避免从第一进水口13和第二进水口14进入的冷热水相互影响。
在一些实施例中，调温模组4还包括弹性复位部件45，弹性复位部件45用于对柱塞41或缸体431施加朝向密封堵头42方向的弹力。
具体的，当第一管体1中的水温较高时，推杆432伸出并抵靠在密封堵头42上，以带动柱塞41移动，进而使得第二进水口14与所述冷水腔体连通。而当第一管体1中的水温降低后，为了避免出水口11出水温度过低，则需要及时的减小或截断第二进水口14与所述冷水腔体之间的水路。而通过配置弹性复位部件45，利用弹性复位部件45施加的弹力，在推杆432回缩时，弹性复位部件45能够驱动柱塞41复位，进而减小或截断第二进水口14与所述冷水腔体之间的水路。
在某一实施例中，弹性复位部件45可以采用弹簧或弹片。以弹簧为例，所述弹簧位于第一管体1中，所述弹簧的一端部抵靠在柱塞41或缸体431上，所述弹簧的另一端部抵靠在第一管体1上。以弹簧抵靠在缸体431上为例进行说明，弹簧能够对缸体431施加弹簧力，弹簧力的方向朝向密封堵头42。当出水口11的温度高于T2并需要进行冷热水混合时，则推杆432抵靠在密封堵头42上，以带动缸体431和柱塞41移动，进而压缩弹簧。而在出水口11的温度低于T2的情况下，则推杆432回缩，并利用弹簧驱动缸体431带动柱塞41反向移动复位，以截断第二进水口14与所述冷水腔体之间的流路。
在某些实施例中，为了方便将弹簧安装在第一管体1内，则第一管体1内部靠近出水口11的位置设置有限位板15，所述弹簧的另一端部抵靠在限位板15上。具体的，限位板15能够对弹簧进行支撑，进而使得弹簧挤压在限位板15和柱塞41或缸体431之间。其中，限位板15可以为环形结构，一方面能够对弹簧起到良好的支撑作用，另一方面环形结构的限位板15能够减少对水流的阻挡，以确保出水口11顺畅的出水。另外，还可以在缸体431上设置有朝向出水口11方向延伸的导向柱433，所述弹簧套在导向柱433上，利用导向柱433能够对弹簧起到支撑定型的作用，进而在压缩弹簧时，以确保弹簧的姿态不会发生歪斜，进而提高组装可靠性。
优选实施例中，为例更加可靠的通过柱塞41来控制第二进水口14与所述冷水腔体之间流路的通断，则在密封堵头42上设置有第一挡圈421， 柱塞41的一端面设置有第二挡圈413，第二挡圈413围绕在贯通孔412的外部；在第一挡圈421与第二挡圈413抵靠在一起后，第一挡圈421的边缘与第二挡圈413的边缘相互配合以形成密封阻水面。
具体的，当需要截断第二进水口14与所述冷水腔体之间的流路时，则第一挡圈421与第二挡圈413抵靠在一起后，在两者之间形成的连接部位构成密封阻水面，以切断第二进水口14与所述冷水腔体之间的流路。而当需要通过第二进水口14进入的冷水与热水进行混合水时，柱塞41移动以使得第二挡圈413远离开第一挡圈421，进而使得第二进水口14与所述冷水腔体之间的流路导通。
同样的，为了更好的起到防烫的目的，则在一实施例中，还可以在第一管体1中设置有台阶面16，台阶面16位于出水口11和第一进水口13之间；柱塞41的一端面设置有第三挡圈，所述第三挡圈与台阶面16之间形成流水间隔。具体的，当需要进行冷热水混合时，由于柱塞41朝向出水口11方向移动，进而使得所述第三挡圈与台阶面16之间形成的流水间隔的距离变小，以实现减少热水的流出量，进而能够更加快捷高效的调节水温以达到防烫的要求。
在某些实施例中，密封堵头42上还设置有定位板422，定位板422能够与推杆432配合，以起到对推杆432施加反向推力的作用。
实施例三，如图8所示，基于上述实施例一和二，为了方便用户或操作人员来调节触发混水的温度，则密封堵头42上螺纹连接有螺杆423，螺杆423的一端部与定位板422连接，螺杆423的另一端部延伸至密封堵头42的外部。当需要调节触发混水的温度时，则通过转动螺杆423来调节定位板422与回缩状态下推杆432之间的距离，便可以调节触发混水的温度。
同样的，在某些特殊情况下，当用户需要用高温水而不需要进行混水的情况下，则通过将螺杆423旋转至外部最大行程处，以使得伸出状态的推杆432不与定位板422接触，进而实现高温出水而不进行混水处理，以实现与截止阀30配置实现高温水的输出，更有利于提高用户对用水温度多样性的要求。
实施例四，如图11所示，本实施例提出了一种电热水器，包括水箱100，水箱100具有进水管101和出水管102，防烫组件200的进水三通10与进水管101连接，防烫组件200的第二管体与出水管102连接。
在本实施例中，有关电热水器的具体结构形式在此不做限制，而对于防烫组件而言，其可以连接在进水管101和出水管102之间，进而水箱100中加热后输出的热水经由出水管102进入到防烫组件200中。同样的，对于进水管101的冷水则通过进水三通10与外界的供水源连接。
以上实施例仅用以说明本发明的技术方案，而非对其进行限制；尽管参照前述实施例对本发明进行了详细的说明，对于本领域的普通技术人员来说，依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或替换，并不使相应技术方案的本质脱离本发明所要求保护的技术方案的精神和范围。
