Abstract

一种光伏电和市电两用的电热水器，公开一种电热水器既可以用市电驱动，又可以用光伏太阳能电源驱动，使其热水器内的冷水达到热水功能。

Description

一种光伏电和市电两用的电热水器
技术领域
本发明涉及一种光伏电和市电两用的电热水器。
背景技术
目前太阳能热水器是用闷热式的热水方法对冷水进行加热，实现热水功能；电热水器采用市电220V对热水器内的冷水进行加热，从而获得热水。
发明内容
本发明一种光伏电和市电两用的电热水器，公开一种电热水器既可以用市电驱动，又可以用光伏太阳能电源驱动，使其热水器内的冷水达到热水功能。
一种光伏电和市电两用的电热水器，其电路由太阳能光伏电池板、逆变器、双投切换开关和电热水器组成。
附图说明
图1是一种光伏电和市电两用的电热水器的电路结构示意图。
具体实施方式
如图1所示，IC1是太阳能光伏电池板，选用输出电压为12VDC的光伏电池板，容量在1000W以上，输出端与逆变器IC2的输入端连接。
如图1所示，IC2是逆变器，选用12VDC转变为220VAC的逆变器，逆变器的输入端与太阳能光伏电池板的输出端相连接，输出端与双投控制开关J连接。
如图1所示，J是双投控制开关，公共端与电热水器相连接，另外两端通过切换触点J，一端与逆变器连接，另一端与市电连接。当有太阳光时，将控制开关投到左边，此时，电热水器的发热管与逆变器连接，太阳能光伏电池板发出的光伏电能，经过逆变器变换成交流220V电源后送给电热水器的发热管，将电热水器内的冷水进行加热；当没有阳光照射时，将控制开关J投到右边，此时，电热水器的发热管与市电连接，由市电220V电源直接供给电热水器工作电源。
如图1所示，IC3是电热水器，选用家电市场销售的电热水器产品，容量约为50立方。
