本申请提出一种储水罐，其应设置为燃气热水器中，所述储水罐设置为缓存热水的同时还设置为将热水进行混合，以使得从所述储水罐排出的热水的温度是稳定的。
在本申请的实施例中，请参照图1，所述储水罐100包括：
罐体10，一端设置有接口11；
转接头20，与所述罐体10固定连接，所述转接头20设置有与所述接口11连通的进水接头、出水接头以及排废接头；以及，
连接管30，安装于所述罐体10内，所述连接管30的一端与所述出水接头连通，所述连接管30的另一端与所述罐体10远离所述接口11的一端间隔设置。
具体的，所述罐体10的形状有很多种，其可以是圆柱状、方体状、多边形状等等，在此对所述罐体10的形状不做具体的限定；所述罐体10的成型方式有多种，其可以是通过钣金件焊接成型，也可以通过铸造的方式成型等等，在此对所述罐体10的形状不做具体的限定。所述罐体10上的接口11设置的位置比较灵活，其可以设置于所述罐体10的端部，也可以设置在所述罐体10的侧部邻近其端部的位置，在此对所述接口11设置的位置不做具体的限定。
所述转接头20与所述罐体10的连接方式有很多种，所述转接头20与所述罐体10可以通过焊接、螺钉连接、插接以及其他连接方式连接固定，在此就不一一列举了；可选地，所述转接头20与所述罐体10之间采用螺钉连接的方式连接固定，即所述罐体10开设有位于所述接口11周缘的多个螺钉孔，所述转接头20贯穿设置有多个螺钉孔，螺钉穿过所述转接头20上的螺钉孔与所述罐体10上对应位置的螺钉孔螺纹连接，这样就能够将所述转接头20与所述罐体10固定连接。
考虑到所述转接头20与所述罐体10之间的密封性，所述罐体10与所述转接头20之间还设置有密封圈（未图示），并且所述转接头20与所述罐体10抵接的表面还凹设有安装槽（未标识），以供所述密封圈安装，这就便于密封圈的定位安装。
所述转接头20上的进水接头的出水端、出水接头的进水端以及排废接头的进水端均设置于所述转接头20的一端，三者可以是同轴设置或者异轴设置，当所述进水接头的出水端、所述出水接头的进水端以及所述排废接头的进水端同轴设置时，三者是呈内外间隔设置的；当所述进水接头的出水端、所述出水接头的进水端以及所述排废接头的进水端异轴设置时，三者可以呈一字型、三角形或者其他形状排布。由于所述进水接头、所述出水接头以及所述排废接头集成于所述转接头20上，这就使得所述罐体10上只需开设有一个接口11即可，这样就大大的减小了所述罐体10上开设的接口11的数量，进而能够降低所述储水罐100出现漏水的风险。
所述连接管30可以是直线型管、螺旋状管、曲线型管等等，只要所述连接管30是两端沿着所述罐体10的延伸方向间隔设置即可，所述连接管30与所述转接头20上的出水接头的连接方式有很多种，例如螺纹连接、插接、焊接等等，在此对所述连接管30与所述出水接头的连接方式不做具体的限定。
应当说的是，所述储水罐100安装至燃气热水器200中时，所述储水罐100的罐体10是沿竖直方向倒置于燃气热水器200的壳体内的，即所述罐体10的接口11是朝下设置的，当向所述罐体10注入热水时，由于所述转接头20上的进水接头的出水端与所述罐体10是直接连通的，所述转接头20上的出水接头是与所述连接管30连通的，并且所述连接管30远离所述转接头20的一端与所述转接头20之间具有一定的间距，这就使得所述罐体10内需要先注入一定量的热水后，所述罐体10内的热水才能够通过所述连接管30排出，这样就使得所述罐体10内始终能够存储一定量的热水；并且储存于所述罐体10内的热水还能够起到调节水温的作用，这就使得设置有所述储水罐100的燃气热水器200的燃烧换热系统220的调节比，即燃烧换热系统220的最低负荷与额定负荷的比值可以达到1:20，这就使得设置有所述储水罐100的燃气热水器200能够更精细的调节热水的温度，进而有利于提高燃气热水器200的性能。
同时，由于自所述转接头20的进水接头进入至所述罐体10内的热水需要流动至所述连接管30远离所述转接头20的一端后才能够排出，这就使得后进入至所述罐体10内的热水自下向上流动时，会使得所述罐体10内的热水不断的翻腾，这样就使得所述罐体10内的热水能够充分的混合，从而使得所述罐体10内部各处水的温度几乎相同，进而确保了从所述罐体10内排出的热水的温度是稳定的，进而有利于提升燃气热水器200的性能。
另外，由于所述储水罐100还具有一定的保温效果，这就使得燃气热水器200刚开启工作的一段时间内，水温较低的热水进入所述罐体10内时，能够与所述储水罐100内温度较高的热水混合后，再排出以供用户使用，这样就确保了燃气热水器200在刚开启工作的一段时间内排出的热水的温度不会太低。
此外，当燃气热水器200停止工作时，燃气热水器200的水管210中的热水在惯性的作用下会继续向所述罐体10内流动，进而使得所述罐体10内部的水位超过所述连接管30远离所述转接头20的一端设置，但是所述连接管30远离所述转接头20的一端与所述罐体10远离所述转接头20的一端是间隔设置的，这就使得所述罐体10内始终存有一定量的空气，而空气具有可压缩的特性，这样就可以缓解所述罐体10中的水锤效应，进而有利于保证所述罐体10的工作寿命。
还需说明的是，混合于所述罐体10的热水中的杂质会在重力的作用下沉淀于所述罐体10的最下方，也即沉淀于所述罐体10邻近所述转接头20的一端，当清洗所述罐体10时，清洁水自所述转接头20的进水接头进入所述罐体10内，并从所述转接头20的排废接头排出，这样一方面确保了清洁水进入所述罐体10内时，能够对沉淀于所述罐体10邻近所述转接头20的一端杂质进行冲洗，以使得杂质从所述转接头20的排废接头排出；另一方面对所述罐体10进行清洁时只需对所述罐体10邻近所述转接头20的一端即可，这样就大大的减小了清洁水的用量。
值得注意的是，自所述转接头20的进水接头进入所述罐体10内部的热水会集中于所述罐体10的中部流动，只有少量后进入所述罐体10内的热水沿着所述罐体10的内壁流动，这就会导致后进入至所述罐体10内部的热水与原先进入所述罐体10内的热水混合不均匀，从而会导致所述罐体10各处的热水温度会有比较小的变动，进而会使得所述储水罐100排出的热水的温度会出现波动，鉴于此，所述储水罐100还设置有导流板40，所述导流板40套设与所述连接管30上并邻近所述接口11设置，并且所述导流板40上还设置有多个导流孔41。
需要说明的是，所述导流板40的面积与所述罐体10的横截面积相当，也即所述导流板40的边缘邻近所述罐体10的内壁面或者与所述罐体10的内壁面抵接，这就使得位于所述导流板40邻近所述接口11一侧的热水在所述导流板40的分流作用下形成多股热水流入所述导流板40远离所述接口11的一侧；并且所述导流板40上的多个导流孔41是自所述导流板40的内侧向所述导流板40的外侧分布的，这样就使得通过所述导流板40后的热水能够均匀的与位于所述导流板40远离所述接口11一侧的热水混合，从而确保了位于所述导流板40远离所述接口11一侧各处的水温相当，进而确保了从所述储水罐100排出的热水温度是稳定的。
根据水在管道内流动的特点可知，管道中部的水量大、水流速度大，邻近管道内壁面处的水量少、水流速度小。鉴于此，请参照图2，将所述导流板40上的导流孔41的密度自所述导流板40内侧向所述导流板40的外侧逐渐增大。如此设置，使得所述导流板40内侧的过水面积要小于所述导流板40外侧的过水面积，但是通过所述导流板40外侧的导流孔41的热水流速度要小于通过所述导流板40内侧的导流孔41的热水流速，根据流体流量计算公式Q=AV（Q为流量值，A为过水面积，V为水流速度）可以得知，在得单位时间内，通过所述导流板40各处的热水水量大致相同，这样就使得位于所述导流板40远离所述接口11一侧各处所补充的热水量大致相当，从而使得所述罐体10内部各处的热水温度大致相同。
显然，为了使后进入所述罐体10内的热水与先进入所述罐体10内的热水均匀混合，请参照图3，还可以将所述导流板40上的导流孔41的孔径自所述导流板40内侧向所述导流板40的外侧逐渐增大。需要说明的是，所述导流孔41的孔径越大，其过水面积就越大，将所述导流板40上的导流孔41的孔径自所述导流板40的内侧向所述导流板40的外侧逐渐增大，这就使得所述导流板40内侧的过水面积小于所述导流板40外侧的过水面积，但是通过所述导流板40内侧的导流孔41的热水流速要大于通过所述导流板40外侧的导流孔41的热水流速，根据流体流量计算公式Q=AV（Q为流量值，A为过水面积，V为水流速度）可以得知，在单位时间内通过所述导流板40内侧的热水量与通过所述导流板40外侧的热水量相当，这样就使得位于所述导流板40远离所述接口11一侧各处所补充的热水量大致相当，从而使得所述罐体10内部各处的热水温度大致相同。
为了使所述储水罐100的保温效果更佳，在本申请的一实施例中，请参照图4，所述储水罐100还包括由保温材料制成的保温件50，所述保温材料可以是泡沫、玻璃棉等，所述保温件50设置为包覆所述罐体10设置，以减缓所述罐体10内热水热量流失的速度，这样就使得所述罐体10内的热水温度能够维持较长的时间，从而使得燃气热水器200在开启工作的一段时间内，温度较低的热水进入所述罐体10内后，可以与所述罐体10内温度较高的热水一起混合后再排出，这样就避免了燃气热水器200开启工作的一段时间内排出的热水温度过低的问题出现。
此外，所述保温件50还能够起缓冲作用，其在所述储水罐100处于搬运或者运输时，还能够对所述储水罐100进行缓冲，这样就有效地避免了所述储水罐100因颠簸而与燃气热水器200的其他部件刚性接触，进而导致所述储水罐100或者所述燃气热水器200的其他部件被撞坏的问题发生。
进一步地，所述保温件50包括两个罩盖51，两所述罩盖51均设置有容置槽。在两所述罩盖51与所述罐体10组装时，两所述罩盖51分别与所述罐体10的一侧扣接，并且两所述罩盖51固定连接，以使所述罐体10完全处于由两个所述罩盖51围设形成的保温腔内，这样就方便了所述保温件50与所述罐体10的组装和拆卸。
需要说明的是，两所述罩盖51上对应设置有供所述罐体10上的接口11伸出的让位孔511。
考虑到所述保温材料被点燃，在本申请的一实施例中，请参照图1，所述储水罐100还设置有阻燃紧固袋60，所述阻燃紧固袋60设置为包覆所述保温件50设置。
需要说明的是，所述阻燃紧固袋60可以采用地毯背胶阻燃剂、硅橡胶阻燃剂等制成，其不仅能够避免所述保温件50被点燃，同时所述阻燃紧固袋60还能够对所述保温件50进行限位，进而使得所述保温件50能够更好的包裹所述储水罐100。
为了方便检测所述罐体10排出热水的水温，所述储水罐100还包括一温度传感器70，所述温度传感器70可以是热电偶、热敏电阻、电阻温度检测器(RTD)等，在此对所述温度传感器70具体为哪一种不做的限定，所述温度传感器70安装于所述温度传感器70安装于所述罐体10远离所述接口11的一端，且所述温度传感器70的感温探头71伸至所述罐体10内的长度要大于或者等于所述连接管30远离所述转接头20的一端与所述罐体10远离所述转接头20一端的间隙，可选地，所述温度传感器70的感温探头71与所述连接管30远离所述转接头20的一端之间的垂直间距为4mm。
应当说的是，后续进入所述罐体10内的热水是自所述罐体10邻近所述转接头20的一端向所述罐体10远离所述转接头20的一端流动的，若所述罐体10远离所述转接头20一端的热水水温满足用户的需求时，也就代表了所述罐体10内的热水满足用户的需求。
也就是说，所述温度传感器70检测的水温大于或等于预设水温时，就代表所述罐体10内的热水满足用户需求，所述温度传感器70检测的水温低于预设水温时，就代表所述罐体10内的热水无法满足用户需求。所述温度传感器70可以将检测结果显示给用户看，同时所述温度传感器70还可以与燃气热水器200的控制器电性连接，并将检测结果发送至燃气热水器200的控制器，燃气热水器200的控制器则可以根据温度传感器70的检测结果，控制燃气热水器200的燃烧换热系统220的换热效率，也即控制所述燃烧换热系统220的火力的大小，以调整所后续进入所述罐体10内的热水的水温，以确保从所述罐体10排出的热水水温满足用户的需求。
值得注意的是，所述温度传感器70的感温探头71可以安装于所述连接管30的外侧，也可以伸至所述连接管30内，可选地，所述温度传感器70的感温探头71自所述连接管30远离所述转接头20的一端伸入所述连接管30内，如此设置，使得所述温度传感器70能够更加精确的检测所述罐体10排出的热水水温。
为了便于所述温度传感器70的安装，请参照图5，所述罐体10远离所述转接头20的一端贯穿设置有安装孔12；所述温度传感器70安装于所述罐体10的外表面，且所述温度传感器70的感温探头71从所述安装孔12伸入所述罐体10内。
应当说明的是，所述温度传感器70的电路板是不能接触水的，将所述温度传感器70的电路板设置于所述罐体10外，将所述温度传感器70的感温探头71伸至所述罐体10内设置，这样一方面便于与所述温度传感器70的电路板电性连接的导线的布置，另一方面还有效地避免了所述温度传感器70的电路板受所述罐体10内的热水的影响。
为了简化所述转接头20的结构，在本申请的一实施例中，请参照图6和图7，所述转接头20包括呈筒状设置的主体部21、第一接头22以及第二接头23；其中，所述主体部21具有内径较大并与所述罐体10的接口11连通的第一段211以及内径较小并与所述第一段211连通的第二段212，所述第二段212形成所述出水接头；所述第一接头22与所述第一段211连通设置，并与所述第一段211一同构成所述进水接头；所述第二接头23与所述第一段211连通设置，并与所述第一段211一同构成所述排废接头。如此设置，巧妙地利用了所述连接管30与所述主体部21的第一段211之间的配合，来将所述主体部21的第一段211与第二段212阻断，从而简化了所述转接头20的接头，进而便于所述转接头20的生产制造。
本申请还提出一种燃气热水器200，请参照图8，该燃气热水器200包括水管210、燃烧换热系统220以及储水罐100，该储水罐100的具体结构参照上述实施例，由于本燃气热水器200采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有效果，在此不再一一赘述。
其中，所述储水罐100的转接头20的进水接头与所述水管210连通，所述储水罐100的转接头20出水接头与所述燃气热水器200的花洒连通，所述储水罐100的转接头20的排废接头与所述燃气热水器200的排废管连通；所述燃气热水器200还包括水泵230以及控制器，所述水泵230的进水端与所述转接头20的出水接头连通，所述水泵230的出水端与所述水管210连通，所述控制器分别与所述储水罐100的温度传感器70、所述燃烧换热系统220以及所述水泵230电性连接，并根据所述温度传感器70的检测结果控制所述水泵230和所述燃烧换热系统220工作。
具体的，当所述温度传感器70检测到所述罐体10内的水温低于预设水温时，所述控制器控制所述水泵230工作，以将所述罐体10内的水抽至所述水管210中，同时所述控制器还控制所述燃烧换热系统220工作，以将所述水管210内的进行加热，从而使得所述罐体10内的热水温度能够保持稳定；当所述温度传感器70检测到所述罐体10内的水温过高时，所述控制器控制所述水泵230工作，以将所述罐体10内的水抽至所述水管210中，同时所述控制器还控制所述燃烧换热系统220关闭或者降低换热效率，以使得自所述罐体10内进入所述水管210中的热水与所述水管210中的冷水混合并经过所述燃烧换热系统220后，得到的热水水温能够满足用户的需求，这样同样可以保证所述罐体10内热水温度能够保持稳定，同时还可以使得所述燃气热水器200能够供应不同温度的热水，从而提高了所述燃气热水器200的性能。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
