Description

一种热水器用电磁发热体组件 技术领域
本发明涉及热水器设备技术领域，更具体地说，涉及一种热水器用电磁发热体组件。
背景技术
电热水器作为现在家庭的常规电器，使用非常广泛。目前，家用电热水器一般有储水式电热水器、即热式电热水器和速热式电热水器，这三种电热水器多数采用电热管直接插入水中的方式进行加热，然而，现在普遍使用的加热管均为直管，这就导致在有限的容积内水不能与加热管的表面充分接触，使得能效转换率低，浪费了电源及单位容积内的热量，而且不能实现水电隔离，存在安全隐患。
发明内容
为克服现有技术的不足，本发明提供一种热水器用电磁发热体组件，在实现物理水电隔离，提高使用安全的前提下，增加发热体的表面积，提高水与发热体的接触面积，提高能效转换效率，节约电源。

优选地，所述壳体的上端套设有连接体，所述连接体包括相贯通的连接部和进水部，所述一级发热管的上端插接在所述连接部内。
优选地，所述冷水进口处沿水流方向依次设有流量计和第一热电 偶。
优选地，所述热水出口处设有第二热电偶。
优选地，所述第二热电偶设于所述壳体的下端的内部。
优选地，所述一级发热管的螺距大于或等于所述一级发热管的管径。
优选地，所述一级发热管的螺距为其管径的两倍。
优选地，所述壳体的上端的侧壁设有连接法兰，所述连接体与所述连接法兰连接。
优选地，所述一级发热管的材质为不锈钢或不锈铁，所述二级发热管的材质为不锈钢。
优选地，所述连接体与所述壳体之间设有密封圈。
本发明的有益效果是：通过在壳体内设置螺旋状的一级发热管和二级发热管，所述二级发热管穿插于所述一级发热管的内部，电磁功率线圈在工作时直接对一级发热管加热，并透过一级发热管每匝之间的间隙给二级发热管加热，不仅充分利用了电磁功率线圈的能量，而且实现了水电隔离，提高了使用安全。当水从冷水进口进入后先从一级发热管的内壁吸收热量并进入到壳体的底部后水位逐渐上升，水位在上升的过程中，水与一级发热管、二级发热管的外壁接触并吸收发热管发出的热量，当水位高于二级发热管的顶端开口截面时，在水压的作用下水流入二级发热管的孔内，并将二级发热管的内壁发出的热量带走。这时，水与一级发热管和二级发热管的内壁、外壁完全接触，使得发热管的热量完全传导给水，提高了能效转换率，节约了能源。本发明结构简单，使用效果好，易于推广使用。
