本发明主要提出一种储水罐，主要应用于燃气热水器中，以存储燃气热水器加热的热水，使燃气热水器工作过程中热水可以连续、稳定的输出。燃气热水器一般包括壳体，燃气组件和导水组件，燃气组件和导水组件都安装于壳体中，导水组件对应燃气组件设置，燃气组件燃烧所产生的热传递至经过导水组件的水，以使水温升高。储水罐设置在导水组件的尾端，加热后的水先流入到储水罐内，再从储水罐中流出供用户使用。
以下将主要描述储水罐的具体结构。
参照图1至图2，在本发明实施例中，该储水罐用于燃气热水器，包括顶盖100和罐体200，所述顶盖100和所述罐体200固定连接围成容腔，所述顶盖100和/或所述罐体200上开设有与所述容腔连通的进水口300和/或出水口400，所述顶盖100和所述罐体200的连接处通过弧面过渡。
具体地，本实施例中，储水罐呈圆柱状设置，顶盖100为周边具有向罐体200弯曲延伸的裙边的盖板，罐体200对应顶盖100的部分具有向顶盖100弯曲延伸的裙边。顶盖100的裙边与罐体200的裙边焊接固定，其中，两个裙边的曲率相同。在罐体200的底部开设有进水口300和出水口400，当然，在其它实施例中，进水口300和出水口400可以开设在其它位置。热水和冷水都可以从进水口300进入储水罐，当然，在一些实施例中，进水口300可以设置两个，分别用于进热水和冷水。在储水罐中充分混合后的热水和冷水从出 水口400流出储水罐。当水从进水口300进入储水罐内时，储水罐内的压强增加，此时，储水罐的侧壁收到水压或气压的挤压。加载在顶盖100和罐体200连接处的载荷，由于弧面的存在，使得载荷被均匀的分布到弧面上，从增加连接处的承载能力。当连接处的两部件受到压力时，相较于两部件相互垂直设置时所受到的张力，位于圆弧过渡上的连接处所承受的张力要小得多。因此将焊接位置设置于圆弧面上时，可有效的增加连接处的承载能力。
当储水罐的罐体200侧壁和顶盖100受到挤压时，罐体200和顶盖100的连接处受到二者分离趋势的张力，连接处受到的张力通过弧面均匀分布到过渡弧面上，使得张力的力度和角度都朝有利于连接处的趋势分布，从而使得连接处可以承载较大的载荷，进而提高了整个储水罐的承载载荷，减少了裂痕、裂纹等的产生，有利于用户更加稳定、安全的使用燃气热水器。
为了更好的分布连接处的载荷，所述弧面为圆弧面，所述圆弧面同时与所述罐体200和所述顶盖100相切，所述圆弧面的圆弧半径为5～20mm。
本实施例中，通过将弧面设置为圆弧面，使得不论连接处位于在弧面的哪个位置，连接处受到的载荷一直为拉力，由于圆弧面过渡，使得圆弧面上不会形成力矩，从而连接处不会受到弯矩的作用。同时，由于圆弧面同时与罐体200和顶盖100相切，使得罐体200和顶盖100均不会对圆弧裙边产生力矩，从而连接处不会收到弯矩作用。减少了连接处承载的种类，避免承载组合交变应力的作用，从而有利于提高储水罐的承载能力。
为了增加罐体200的承载强度，所述罐体200包括罐身210和底盖220，所述罐身210远离所述顶盖100的一端与所述底盖220圆弧过渡连接。
本实施例中，罐体200由罐身210和底盖220两部拼接而成，罐身210远离底盖220的一端与顶盖100焊接。罐身210与底盖220的连接关系和存在的问题，与罐体200与顶盖100连接存在的问题相同。因此，我们解决罐身210与底盖220之间的连接处的应力集中的方式相同。因此，通过圆弧过渡罐身210与底盖220之间的连接处，其工作原理与罐体200与顶盖100之间工作原理相同，在此不再赘述。值得说明的是，在一些实施例中，罐身210和底盖220可以一体成型设置。
为了使从进水口300进入储水罐内的水混合更加均匀，所述储水罐还包括出水管500；所述出水管500位于所述容腔内，所述出水管500的侧壁上开设有若干的入水孔510，所述入水孔510连通所述容腔和所述出水管500，所述出水管500的上端封闭，所述出水管500的下端敞开形成排水口520且排水口520与所述出水口400连通。
本实施例中，出水管500的入水孔510开设在出水管500的管壁上，入水孔510的形状在此不做限定，可以为圆孔、方孔以及其它可通过流体的形状均可。入水孔510在管壁 上呈矩阵排列，使得容腔中的水均匀的进入出水管500内。容腔中冷水和热水均通过入水孔510进入出水管500中，使得冷水和热水在流动的过程中充分混合，使得从出水口400流出的水的温度恒定，有利于用户更好使用燃气热水器。
为了将储水罐内的水排尽，所述出水管500上位于最下方的入水孔510的最低点与所述容腔的底面在上下方向上平齐，即所述出水管500具有孔壁与所述罐体200底部平齐的入水孔510。在出水管500靠近出水口400的位置，至少有一个入水孔510的孔壁与罐体200底部平齐，使得罐体200中的水可以通过该入水孔510排放干净。有利于储水罐内的水循环，避免储水罐内存在腐水，而滋生细菌的现象出现。
其中，为了使得出水管500的排水速度和冷热水的混合率兼得，与所述罐体200底部平齐的入水孔510的孔径为4～10mm。当入水孔510的孔径太大时，冷水和热水的混合率得不到保证，当孔径太少时，出水口400的流量得不到保证。因此，将入水孔510的孔径设置为4～10mm，以使排水速度和冷热水的混合率同时得到保证。
为了使储水罐内的水混合更加均匀，所述储水罐还包括进水管600，所述进水管600设在所述容腔内，所述进水管600的上端封闭，所述进水管600的下端敞开且与进水口(300)连通，所述进水管(600)的侧壁上设有背向所述出水管(500)的入水口610。
本实施例中，入水口610开设在入水管的侧壁上，水流从进水口300流入进水管600，然后从进水管600的入水口610流入容腔。其中，入水口610背对出水管500设置，使得水流朝背对出水管500的方向流出，使得水流需要在储水罐内循环流动一定距离后才能进入出水管500，使得从进水管600流入的水充分的与储水罐中的水混合。
为了便于进水口300和出水口400的加工，所述进水口300和所述出水口400关于所述罐体200的中心轴线对称设置。通过将进水口300和出水口400对称设置，在加工过程中，进水口300和出水口400可以同时加工，又有利于提高加工效率。同时，由于进水口300和出水口400对称设置，使得进水和出水时，对储水罐的影响减小，使得进水和出水都更加均匀。
为了使燃气热水器的加热速度和冷热水的混合率兼得，所述容腔的容量为1～3L。本实施例中，将储水罐的容量设置为1～3L，当容量太小时，冷水和热水混合不充分，影响用户的体验，当容量太大时，水温上升较慢，需要加热较长才可以使用，不利于用户快速的使用热水。
为了提高储水罐的保温效果，所述储水罐还包括保温件700，所述保温件700包裹于所述顶盖100和/或所述罐体200的外壁上。本实施例中，保温件700为柔性的棉织物材质，可缠绕包裹罐体200和顶盖100。当然，保温材料也可为聚苯乙烯泡沫塑料等，直接发泡在外侧壁上。
当然，在一些实施例中，储水罐还可以包括安装支架800，安装支架800与储水罐的侧壁固定连接，储水罐通过安装支架800固定设置于墙体上。
本发明还提出一种燃气热水器，该燃气热水器包括储水罐，该储水罐的具体结构参照上述实施例，由于本燃气热水器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有益效果，在此不再一一赘述。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明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发明的专利保护范围内。
