防止燃气热水器误熄火的装置
本技术涉及一种燃气安全设备,尤其涉及一种防止燃气热水器误熄火的装置。
技术介绍
家用燃气热水器在热水流量降低到接近其最低稳定燃烧流量的时候会立即熄火以防燃烧室过热,但在洗澡(特别是淋浴)时,在花洒喷头之间切换或调整水温时候,及容易导致热水被切断或流量接近最低稳定燃烧流量,虽然这一过程一般不超过0.5秒,但是这时热水器自动判定为热水关闭,也会立即熄火,并自动进入燃烧室降温、扫气通风的善后工作阶段,这时候,即使再打开热水龙头,热水器也不能立即恢复燃烧,导致热水中断,影响洗浴体验。现在市面上的热水器多位恒温热水器,但这个恒温,仅仅是燃烧稳定时候输出热水恒温。对于燃气热水器,为了防止热水器熄火重启过程中出水温度出现大幅波动,一般有两类方案:一是使用一个电加热器与燃气热水器串联,在燃气热水器换热器输出的水为冷水时,电加热器自动工作;上述现有方案虽然结构简单,但对燃气热水器的电力要求较高,会造成家庭电压波动,且一般家庭的燃气热水器安装处的预埋线路普遍截面积不大,无法瞒住这一方案对电力的需求;且电加热器功率大能耗高,其长期使用费用较高。二是在燃气热水 ...
