在本实施方式中, 当儿童玩弄儿童防烫伤饮水机 100时, 由于儿童身 高小于儿童防烫伤饮水机 100的机体前端上部的红外线检测装置 110的高 度, 红外线检测装置 110发射的红外线未被反射, 故没有接收红外线而无 法输出检测信号。 相应地, 微处理器 130因未接收到红外线检测装置 110 输出的检测信号, 从而无法输出第一控制信号, 故热水管道电磁阀 140关 闭儿童防烫伤饮水机 100的热水管道。 因此, 当儿童打开热水开关后不会 流出热水或开水, 从而避免烫伤事故。
当成人使用儿童防烫伤饮水机 100时, 由于成人身高大于儿童防烫伤 饮水机 100的机体前端上部的红外线检测装置 110的高度, 红外线检测装 置 110发射的红外线被用户反射, 从而接收红外线并输出检测信号。 相应 地, 微处理器 130接收红外线检测装置 110输出的检测信号, 并输出第一 控制信号。 热水管道电磁阀 140根据微处理器 130输出的第一控制信号导 通儿童防烫伤饮水机 100的热水管道。 因此, 当成人打开热水开关后流出 热水或开水, 从而不影响正常使用。

图 3为本发明提供的儿童防烫伤饮水机 100的另一种实施方式的电路 模块示意图。如图 3所示,儿童防烫伤饮水机 100包括红外线检测装置 110、 供电模块 120、微处理器 130、热水管道电磁阀 140及报警装置 150。其中, 图 3中的红外线检测装置 110、供电模块 120及热水管道电磁阀 140与图 1 所示相同, 故在此不再复述。 图 3中的微处理器 130与图 1所示的区别在 于当未接收到红外线检测装置 100输出的检测信号时检测热水开关的状 态, 并当热水开关打开时输出第二控制信号。 报警装置 150用于根据微处 理器 130输出的第二控制信号进行 警。
图 4为图 3所示的儿童防烫伤饮水机 100的具体电路示意图。 如图 4 所示红外线检测装置 110、 供电模块 120及热水管道电磁阀 140与图 2所 示相同, 故在此不再复述。 图 4中的微处理器 130与图 2所示的区别在于 还包括第二控制引脚 PA3, 用于输出第二控制信号。

在本实施方式中, 当儿童玩弄儿童防烫伤饮水机 100时, 由于儿童身 高小于儿童防烫伤饮水机 100的机体前端上部的红外线检测装置 110的高 度, 红外线检测装置 110发射的红外线未被反射, 故没有接收红外线而无 法输出检测信号。 相应地, 微处理器 130因未接收到红外线检测装置 110 输出的检测信号, 从而无法输出第一控制信号, 故热水管道电磁阀 140关 闭儿童防烫伤饮水机 100的热水管道。 因此, 当儿童打开热水开关后不会 流出热水或开水, 从而避免烫伤事故。 同时, 微处理器 130检测到热水开 关打开, 相应输出第二控制信号。 报警装置 150根据微处理器 130输出第 二控制信号进行报警, 从而提醒儿童的家长阻止儿童继续儿童防烫伤饮水 机 100。
图 5为本发明提供的儿童防烫伤饮水机 100的示意图。 如图 5所示, 本发明提供的儿童防烫伤饮水机 100的机体前端上部设置有红外线检测装 置 110, 用于发射红外线, 并接收由用户反射的红外线, 从而相应开启热 水管道。 图 5中所示的儿童防烫伤饮水机 100为拒式饮水机, 其机体前端 上部的高度大于儿童身高。 当儿童玩弄儿童防烫伤饮水机 100时, 红外线 检测装置 110因未接收到反射的红外线而相应关闭热水管道, 因此热水开 关打开后不会流出热水或开水, 从而避免烫伤事故。 同时, 拒式饮水机的 机体前端上部的高度小于成人身高。当成人使用儿童防烫伤饮水机 100时, 红外线检测装置 110因接收到反射的红外线而相应打开热水通道, 因此打 开热水开关会流出热水或开水, 从而不影响正常使用。 为更好的理解本发 明, 图 1中仅以拒式饮水机为例。 在其它实施方式中, 本发明提供的儿童 防烫伤饮水机 100还适用于台式饮水机, 只需利用支撑装置改变台式饮水 机的高度即可实现拒式饮水机相同的效果。
本发明提供的儿童防烫伤饮水机, 通过在机体前端上部设置红外线检 测装置判断用户为成人或儿童, 相应控制热水管道电磁阀导通或关闭热水 管道, 从而有效防止儿童烫伤, 同时不影响成人使用饮水机。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说 明, 不能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术 领域的普通技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若 干筒单推演或替换, 都应当视为属于本发明的保护范围。
