具体实施方式
下面结合实施例对本申请做进一步说明，但不局限于说明书上的内容。
如图1至图3所示的实施例一，本申请公开了一种加湿电暖器，包括壳体10、加热装置20和蒸发盘30，壳体10上设置有出风口11；加热装置20设置在壳体10内部，加热装置20由加热管和翅片组成，加热管加热后通过翅片辐射热量；蒸发盘30设置在壳体10内部，并且蒸发盘30位于加热装置20和出风口11之间；蒸发盘30具有过流通道321，加热装置20加热后的空气通过过流通道321穿过蒸发盘30并流向出风口11。
当加湿电暖器正常工作时，气流经过加热装置20，气流变成暖风后通过过流通道321穿过蒸发盘30并流向出风口11，再由出风口11吹出，以使周围环境温度上升，达到舒适的温暖环境。暖风在通过过流通道321后，会将蒸发盘30处的蒸发水带走，从出风口11排出，从而提升了环境湿度，使人体处于一个舒适的环境。本申请通过蒸发盘30上设置过流通道321，使暖风可以直接由过流通道321穿过蒸发盘30，从而避免了暖风绕过蒸发盘30，使气流流动更加顺畅，提升加热效果。
另外，蒸发盘30内的水既能通过加热装置20的热辐射完成蒸发，还能通过暖风蒸发，尤其是暖风流经过流通道321过程中，还可以对过流通道321内壁进行加热，加热后的过流通道321内壁再对蒸发盘30内 的水进行加热，提高了热交换的面积，大大增加了水分蒸发效率。相比于相关技术来说，本申请的加湿电暖器，不仅加热效果好，利用蒸发孔的结构，蒸发效率更高，加湿效果也更好。
蒸发盘30设置有蒸发槽31，蒸发槽31的槽底穿设有过流管32，过流管32内形成有过流通道321，过流管32的外壁与蒸发槽31的内壁之间形成储水空间40。通过设置过流管32，一方面将过流管32穿设在蒸发槽31的槽底，使暖风可以通过过流管32内的过流通道321穿过蒸发盘30，从而避免暖风绕过蒸发盘30，使暖风流动更加顺畅，提高加热效果；另一方面，过流管32的外壁与蒸发槽31的内壁之间形成储水空间40，蒸发水可以在储水空间40内受热蒸发，过流管32的外壁可以将蒸发水挡住，避免蒸发水流入过流通道321内，提高可靠性；最后，与没有过流通道321的蒸发水盘相比，增加过流管32后，蒸发盘30的整体换热面面积更大，因此，与暖风的热交换效率更高，使蒸发水的蒸发速率更高，加湿效果更好。
蒸发盘30的第一侧朝向加热装置20，蒸发盘30的第二侧朝向出风口11，蒸发盘30的第二侧形成有蒸发槽31；过流管32自蒸发盘30的第一侧贯穿至第二侧。通过设置过流管32，使暖风可以通过过流管32从蒸发盘30的第一侧直接穿至蒸发盘30的第二侧，从而避免暖风绕过蒸发盘30，减少了暖风的流动路径，降低了风量损失，使暖风流动更加顺畅，提高加热效果。
为了提高暖风的流通率，可以将过流通道321设置为多个，多个过流通道321间隔设置。
蒸发槽31的槽壁上还设置有溢流孔33，蒸发盘30中的水通过溢流孔33回流至加湿电暖器的水箱。通过设置溢流孔33，当蒸发水水位到达溢流孔33位置时，多余的蒸发水会通过溢流孔33回流至水箱50，从而避免蒸发水溢出，节约资源。
在图未示出的实施例二中，其结构与实施例一基本相同，区别在于，蒸发槽31的槽壁上还设置有溢流孔33；加湿电暖器还包括湿帘组件，湿帘组件设置在壳体10内，蒸发盘30通过溢流孔33给湿帘组件供水，溢流孔33流出的水流经湿帘组件后回流至加湿电暖器的水箱50。蒸发盘30中被加热过的蒸发水通过溢流孔33流到湿帘组件上，其中湿 帘组件包括与溢流孔33连通的分水盒和设置在分水盒下方的湿帘，蒸发水通过分水盒均匀分布在湿帘上，一部分水通过气流流动而蒸发，起到加湿的效果。由于流向湿帘的水在蒸发盘30中吸收了热量，水温升高，蒸发速度加快，加湿效果相比常温水更好，加湿量增加。蒸发盘30与湿帘同时双重加湿，明显提升加湿量。
如图3所示的实施例一中，出风口11位于加热装置20的上方位置处。也就是说，蒸发盘30也是位于加热装置20上方的，蒸发槽31也是朝向出风口11的。当蒸发盘30中的水经高温的发热装置加热后，部分水会从蒸发槽31蒸发至上方，然后被气流带走送出，进而实现加湿，提升环境湿度。因此，将出风口11设置在加湿装置的上方，能够进一步地提升蒸发效率，提升加湿效果。
为了进一步增加出风效率，本实施例一的加湿电暖器的壳体10包括顶板，顶板上开设有出风口11。出风口11设置在顶板的优点是利用暖风气流上浮的特性，使暖风气流自行向出风口11处流动，不仅可以优化气流流动，增加其出风效率，还可以减小耗能，降低风机的转速。
在一些实施方式中，加湿电暖器还包括水箱50、水泵60、液位传感器和控制装置，蒸发盘30的进水口与水箱50连通，水箱50用于向蒸发盘30内供水。水泵60将水箱50内的水抽至蒸发盘30内；液位传感器设置在蒸发盘30上，液位传感器用于检测蒸发盘30内的水位；控制装置分别与液位传感器、水泵60电连接，控制装置用于根据蒸发盘30内的水位，控制水泵60运行或停止。在水快要蒸发完时水泵60开始工作，向蒸发盘30中补充水，水位补充到设定目标后水泵60再次停止工作，此为水的蒸发补充过程。通过这种补水方式可以保证蒸发盘30中一部分水完全蒸发完后再补水，这样可以提高水的蒸发量。
在图未示出的实施例三中，其结构与实施例一基本相同，区别在于，加湿电暖器还包括水泵60和定时装置，水泵60将水箱50内的水抽至蒸发盘30内；水泵60将水箱50内的水抽至蒸发盘30内，定时装置与水泵60电连接，定时装置用于控制水泵60间隔启动，以使水泵60向蒸发盘30内间隔补充水。从而保证蒸发水的水量，进而提高蒸发量。
在图未示出的实施例四中，其结构与实施例一基本相同，区别在于，水箱50的位置高度大于蒸发盘30的位置高度；水箱50底部与蒸发 盘30的进水口连通，蒸发盘30的进水口位置处设置有用于开闭进水口的控制阀；蒸发盘30内设置有浮子，浮子与控制阀驱动连接，浮子用于根据蒸发盘30内的液位高度，控制控制阀开启或关闭。通过设置浮子可以通过蒸发盘30内的液位高度控制控制阀开启或关闭，从而实现对蒸发盘30的及时补水，从而保证蒸发水的水量，进而提高蒸发量。
在图3所示的实施例一中，壳体10上设置有进风口13；加湿电暖器还包括风机，风机设置在壳体10内部且位于进风口13与加热装置20之间。进风口13设置在加湿电暖器的中部或者底部，气流由中部或者底部进入后，由顶部的出风口11吹出。蒸发盘30中被加热过的水通过溢流孔33流到湿帘上，在风机带动下干燥的空气从进风格栅进入，经过湿润的湿帘后，带走一部分水，从上方的出风栅吹出，起到加湿的效果。流向湿帘的水由于在蒸发盘30中吸收了热量，水温升高，蒸发速度加快，加湿效果相比常温水更好，加湿量增加。蒸发盘30与湿帘同时双重加湿，明显提升加湿量。
显然，本申请的上述实施方式仅仅是为清楚地说明本申请所作的举例，而并非是对本申请的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无法对所有的实施方式予以穷举。凡是属于本申请的技术方案所引伸出的显而易见的变化或变动仍处于本申请的保护范围之列。
