Description

发热器以及即热式电热水机
技术领域
本实用新型涉及电热水机技术领域，更具体地说，是涉及一种发热器以及即热式电热水机。
背景技术
现有技术中的热水机大都采用储水加热式发热器，使用这种热水机时，须先将发热器内储存的所有水加热到所需的温度，才能得到所需温度的热水，这就造成了电能的浪费。而当发热器内的热水用完后，如果想继续使用热水，则需要从水箱向发热器重新注水、加热，这个过程需要持续较长时间，从而不能实现即时供应热水的功能。
另外，现有技术中的热水机在不同的环境温度下使用时，用户得到的热水温度也会不同，当外界温度较高时，所得热水的温度相应较高，而当外界温度较低时，所得热水的温度也会较低。而且，现有技术中由于温控系统的缺陷，故不能保证所得热水温度的准确性。
实用新型内容
本实用新型所要解决的技术问题在于提供一种发热器，其可实现对冷水的快速加热。
本实用新型所要解决的另一技术问题在于提供一种具有上述加热器的即热式电热水机。
对于本实用新型发热器来说，上述技术问题是这样加以解决的：提供一种发热器：包括电热管，还包括设有弯曲流水通道的金属导热体，所述电热管包覆于所述金属导热体内。
更具体地，所述金属导热体由铸铝构成，所述流水通道由盘绕在一起并呈螺旋状的金属管所形成。
更具体地，所述电热管和金属管通过压铸的方式包覆于所述金属导热体内。
更具体地，所述电热管亦呈螺旋状并环绕于所述金属管外周。
更具体地，还包括控制电路，所述金属导热体上设有与所述控制电路电连接的热敏电阻。
更具体地，所述金属导热体对应所述电热管的位置设有环状突起。
更具体地，所述金属管的内径为1-4毫米，所述电热管的外径为5-10毫米，功率在1000-2300瓦之间。
更具体地，所述金属管的内壁上设有螺纹。
对于本实用新型即热式电热水机来说，上述技术问题是这样加以解决的：提供一种即热式电热水机，包括水箱，与所述水箱出水口连通的发热器，所述发热器具有上述的结构。
更具体地，在所述水箱与所述发热器之间设有水泵。
这样，由于所述电热管呈螺旋状，通过压铸的方式包覆于所述金属导热体内，增大了传热面积；而且，所述流水通道呈螺旋形，并通过压铸的方式形成于金属导热体内，所述金属管的内壁上设有螺纹，增大了受热面积，从而可以实现对冷水的即时加热。
附图说明
图1是本实用新型即热式电热水机一较佳实施例的剖视示意图；
图2是图1所示实施例中发热器的剖视示意图；
图3是图1所示实施例中发热器的立体分解示意图。
具体实施方式
为了使本实用新型所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
请参照图1，为本实用新型即热式电热水机的一较佳实施例，该即热式电热水机包括水箱1、与所述水箱1出水口连通的发热器2以及控制电路。即热式电热水机还设有操作按钮3、与所述发热器2出水口连接的出水嘴4等。
以下对上述各组成部分分别作详细介绍。
请参照图2及图3，发热器2包括电热管21以及设有弯曲流水通道的金属导热体22，所述电热管21包覆于所述金属导热体22内。本实施例中，所述金属导热体22由铸铝构成，所述流水通道由盘绕在一起并呈螺旋状的金属管23所形成。所述电热管21和金属管23通过压铸的方式包覆于所述金属导热体22内。当然，所述金属导热体22还可以采用其他易于传热的金属或者合金构成。
为了使金属管23内的冷水受热更加均匀，所述电热管21亦呈螺旋状并环绕于所述金属管23的外周。
为了使电热管21所产生的热量更易于向的金属管23传递，所述金属导热体22对应所述电热管21的位置设有环状突起221。
另外，所述金属管23的内壁上设有螺纹。螺纹的设置不仅可以有效增大换热面积，提高热交换率，而且在水压推动下，能够使流经金属管23的冷水产生涡旋搅拌作用，这样即加大水的推动力、防止水垢的产生和沉淀、起到了管壁的自洁功能。
更具体地，在所述水箱1与所述发热器2之间设有水泵5。所述金属管的内径为1-4毫米，所述电热管的外径为5-10毫米，功率在1000-2300瓦之间。这些参数的设置，可以使从水箱流出的冷水快速被加热变成95℃以上，再经过出水嘴4流出，实现连续出热水的功能。
本实施例还包括控制电路(图中未示出)，所述金属导热体22上设有与所述控制电路电连接的热敏电阻6。而且，为了防止在不同环境温度下使用时，用户得到热水温度不同的缺陷，本实施例设有一个可独立操作的热敏电阻7，用以直接探测出水口的热水温度，利用可控硅控制水泵5的通断，这样就能够控制水泵的流量大小，使得出水口的热水温度不会受到环境温度高低的影响而发生变化。
另外，本实施例在水泵5入水管处还设有抽干保护器8，该抽干保护器8由引线以及与所述引线电连接的两个金属体构成，用作探测水泵入水管内水的电阻变化，当水箱内的水被抽干时，电阻值发生变化的信号被传至控制电路，控制电路即发出控制信号将发热器2及水泵5的电源切断，使得发热器2不会因为干烧而过热，水泵5不会因为抽空而被损坏。
综上，由于所述电热管21呈螺旋状，通过压铸的方式包覆于所述金属导热体22内，增大了传热面积；而且，所述流水通道呈螺旋形，并通过压铸的方式形成于金属导热体22内，所述金属管23的内壁上设有螺纹，增大了受热面积，起到管壁自洁功能，从而可以实现对冷水的即时加热。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
