Description

红外线瓦斯炉具的炉心结构
技术领域
本发明涉及一种红外线瓦斯炉具的炉心结构， 该炉心能适用于携带型 瓦斯炉、 家用型瓦斯炉、 及瓦斯热水器等。 背景技术
现有红外线瓦斯炉的构造， 主要包含： 点火装置、 炉心、 及出气调节 装置， 其火焰是由炉心设置的复数个焰孔直接发出后， 以对器亚上的食物 进行加热， 但使用上遇风吹袭时， 火焰极易被吹熄； 又当烹煮食物时， 滚 烫的汤水溢出后会淋湿炉心， 把火焰浇熄， 此时瓦斯仍是持续排出， 如果 使用者未发现火焰熄灭， 且未及时将瓦斯关闭， 将造成气爆等危险意外发 生。 因此， 即有业者研发改进， 其在炉心设置底盖、 分气构件、 及多孔炉 板等构件， 以使瓦斯通过分气构件后， 经多孔炉板点火产生火焰， 由于瓦 斯是由多孔炉板上细密小孔输出后再燃烧产生火焰， 因此利用多孔炉板的 防护， 能降低火焰易被风吹熄或浇熄等问题发生。
以下即有两件针对上述问题改进、 并已公开的专利文献， 分别是： 专利文献 1 , 为中国台湾公告第 M387967号 「瓦斯炉头及使用其之可携式 瓦斯炉具」 ， 即为现有市面常见的具有分气构件及多孔炉板构造的瓦斯炉 具之炉心构造， 其主要包括一上盖； 一多孔炉板设于上盖下方， 具有多个 通孔， 以供瓦斯流出； 一网件设于多孔炉板下， 具有众多网目； 一多孔分 气构件， 位设于网件之下， 于该多孔分气构件上设有众多通孔以供瓦斯流 通； 一底盖， 其与上盖接合而将多孔炉板、 网件及多孔分气构件夹于其间， 且使该多孔炉板、 网件及多孔分气构件周侧与底盖容槽壁密合接触， 以保 持组设稳固性， 避免该多孔炉板、 网件及多孔分气构件于底盖内产生晃动。 据此， 欲使用时， 瓦斯由底盖中央通孔输出， 继经由多孔分气构件上的孔 洞， 以将瓦斯导引分流， 再经网件的网目后由多孔炉板分布的小孔流出， 续经由点火装置点燃后燃烧， 以对器亚上食物进行加热或烹煮。
专利文献 2, 为中国台湾公告第 M387967号之「瓦斯炉头及使用其之 可携式瓦斯炉具」 ， 于使用实施上， 其瓦斯由多孔分气构件的孔洞经网件 及多孔炉板流出， 并集中于中央处产生炉火， 当器亚放置于瓦斯炉头时， 器亚会对应遮覆于中央炉火上方， 以对器亚内容置的食物进行加热或烹煮， 外部空气的接触， 因此在缺乏空气的助燃下， 造成瓦斯燃烧不完全现象， 依国家标准安全规定， 瓦斯炉具其释放于空气的一氧化碳含量至少须低于
1,400PPM, 以避免瓦斯炉具于使用时因释放于空气中的一氧化碳过高， 而 造成使用者一氧化碳中毒的危险， 因此， 若将瓦斯炉具使用时释放于空气 中的一氧化碳含量降低， 将有利于使用上安全性， 同时， 更可以减少瓦斯 燃烧不完全， 造成瓦斯不当的浪费， 更能使热效率得以提升。 发明内容

以下依据图面所示的实施例详细说明如后: 请参阅图 1、 图 2所示， 为本发明红外线瓦斯炉具的炉心结构第一实 施例型态， 其主要设有一底盖 1 , 并于底盖 1内形成一容槽 11 , 该容槽 11 的槽底中央具有瓦斯通孔 12, 另在底盖 1的容槽 11内设置一导流板 2, 在 导流板 2上方还设置一红外线陶片 3 , 其组设于底盖 1的容槽 11槽口上， 而红外线陶片 3具有细密小孔以供瓦斯流出； 再者， 红外线陶片 3是藉由 一环形上盖 4固定在底盖 1的槽口上，其中央具有镂空孔 41以棵露出红外 线陶片 3。
导流板 2在容槽 11 内被予托高， 该导流板 2与底盖 1的容槽 11槽底 之间存在着间距 6, 以使瓦斯通孔 12不被覆盖， 又导流板 2的周侧设置了 让瓦斯大量通过的间隙 7 , 使瓦斯由瓦斯通孔 12进入容槽 11后， 通过间 距 6再由导流板 2的周侧间隙 7朝上流动， 以作为瓦斯流动的主要动线。 上述导流板 2与底盖容槽 11之间是以架高部 5予以架高， 而且导流板 2的 外径小于容槽 11的内径， 使导流板 2的外周缘与容槽 11的内壁之间形成 环状的间隙 7。
上述架高部 5是至少由两个中空管体 51组成， 其以底槽 11 中央为圓 心呈等间距相对应设置， 其上、 下端分别抵着导流板 2的底面及容槽 11的 槽底， 又容槽 11的槽底至少设置两个对应中空管体 51的锁孔 13 , 以供如 螺栓的锁固件 52由下往上穿入后， 再穿过中空管体 51 的管孔 511、 及导 流板 2预设的锁孔 21 , 再与螺帽 53螺合固定， 因此锁固件 52的端头 521 会外露在底盖 1底面。 据此， 能将底盖 1、 导流板 2及架高部 5予以组合 固定， 并使导流板 2与红外线陶片 3之间也产生适当间距。
请同参图 3所示， 为便于本发明的介绍， 本图以携带型瓦斯炉为例来 线瓦斯炉具的出气调节装置 8後，隐藏在炉具内部的储存槽 (未揭)提供瓦斯 并流往炉心底盖 1的瓦斯通孔 12内， 再流入容槽 11 内部； 由于导流板 2 与底盖 1的容槽 11槽底间， 有架高部 5撑高导流板 2而产生间距 6, 更因 导流板 2周侧与底盖 1的容槽 11槽壁间具有间隙 7, 故由底盖 1的瓦斯通 孔 12流进容槽 11 内的瓦斯， 能由上述间距 6流经间隙 7 , 再由导流板 2 周边往上流窜至红外线陶片 3的周侧， 然后由红外线陶片 3周侧的细密小 孔中往上输出， 在点火装置的点火后， 使瓦斯进行燃烧， 以对放置于红外 线陶片 3上方的器亚进行加热或烹煮。 其次， 在图 2的揭示中， 可发现红 外线陶片 3上方的周边火焰比中央火焰为大， 这是因为周边的瓦斯流量大 于中央， 所以周边火势大于中央火势。
由于红外线陶片 3 的周侧未受器亚所遮覆， 故瓦斯能与周遭空气进行 接触， 因此在空气充分助燃下， 使红外线陶片 3周侧输出的瓦斯能完全燃 烧， 更使热效率得以大大提升。 本发明亦经 「财团法人台湾燃气器具研发 中心」 以 CNS14529检测标准对其进行检测， 发现释放于空气中的一氧化 碳含量为 0.0084 % , 低于目前排放标准 1,400PPM 以下。 由此可知， 使用 本发明红外线瓦斯炉具的炉心结构， 于使用状态中释放空气中的一氧化碳 含量极低， 故能减少一氧化碳的排放， 大幅提高使用安全性， 同时， 在瓦 斯全燃烧的状态下， 能避免瓦斯的浪费。
上述中， 架高部 5 的实施型态具有多种， 以下以图式来进一步说明架高部 5与间距 6的关系。
请参图 4所示， 为本发明炉心的第二实施例图， 与第一实施例图不同 的是， 所述架高部 5是至少由两个底盖容槽 11槽底往上连伸的支柱 54组 成， 该支柱 54上具有锁孔 541 , 且上端顶着导流板 2的底面， 又导流板 2 至少设置两个对应上述支柱 54的锁孔 21 , 以供如螺栓的锁固件 52由上往 下穿过后， 再螺入支柱 54的锁孔 541 内而螺合固定； 据此， 将导流板 2 架高， 并与底盖 1容槽 11槽底形成间距 6。
请参图 5所示， 为本发明炉心的第三实施例图， 与第二实施例图不同 的是， 所述架高部 (5)是至少由两个底盖容槽（11)槽底往上连伸的支柱 (54) 组成， 该支柱 (54)的上端与导流板 (2)连接， 使得底盖（1)、 支柱 (54)及导流板 (2)—体成型；据此，将导流板 2架高，并与底盖 1容槽 11槽底形成间距 6。
请参图 6所示， 为本发明炉心的第四实施例图， 与上述实施例不同的是 所述架高部 5是至少由两个自该底盖 1容槽 11槽底往上连伸的凸块 55组 成， 该凸块 55上端内缘设置下凹的凹阶 551 , 以供导流板 2的外缘能嵌入 在凹阶 551上而予以固定； 据此， 将导流板 2架高， 并与底盖 1容槽 11槽 底形成间距 6。 请参图 7所示， 为本发明炉心的第五实施例图， 与上述实施例不同的 是， 所述架高部 5是至少由一弹片 56组成， 该弹片 56锁接于该导流板 2 底面， 且该弹片 56 两侧往下拗折形成两弹性支脚 561 ; 另在底盖容槽 11 槽壁形成至少两个对应上述弹性支脚 561的卡槽 57 ,以供上述弹性支脚 (561) 卡入后固定； 据此， 将导流板 2架高， 并与底盖 1容槽 11槽底形成间距 6。
请参图 8所示， 为本发明炉心的第六实施例图， 与上述实施例不同的 是，所述架高部 5是导流板 2周缘处往下沖压出拗折的弹性支脚 22所形成， 而该底盖容槽 11槽壁处形成与上述弹性支脚 22对应的卡槽 57 , 以供弹性 支脚 22卡入后固定； 据此， 将导流板 2架高， 并与底盖 1容槽 11槽底形 成间距 6。
请参图 9所示， 为本发明炉心的第七实施例图， 与上述实施例不同的 是， 所述架高部 5至少为一弹性件 58 , 该弹性件 58上端组接在导流板 2 的底面， 而另端是抵撑在底盖容槽 11的槽底； 据此， 将导流板 2架高， 并 与底盖 1容槽 11槽底形成间距 6。
请参图 10所示， 为本发明炉心的第八实施例图， 该炉心与上述实施例 不同的是， 导流板 2设置了复数个小孔 25; 请同参图 11所示， 当瓦斯由 瓦斯通孔 12进入容槽 11后， 以导流板 2的周侧间隙 7 , 成为瓦斯的主要 流动路线， 而复数个小孔 12则成为小量瓦斯的流动路线， 如此一来， 大火 焰集中在红外线陶片 3的周侧， 而小火焰则分布在红外线陶片 3的中央区 域。
请参图 12所示， 为本发明炉心的第九实施例图， 该炉心与上述实施例 不同的是， 导流板 2的外径接近容槽 11的最大内径， 而且导流板 2的周缘 卡固在底盖容槽 11的槽壁处； 再同参图 13所示， 导流板 2的外环区分布 了多个能使瓦斯通过的切口槽 24 , 该切口槽 24以等角度分布， 如此一来， 瓦斯由瓦斯通孔 12进入容槽 11后， 以导流板 2的外环区的切口槽 24成为 周侧间隙 7 , 而为瓦斯的主要流动路线。 此， 凡与本发明所属技术手段相同或近似的等效手段直接置换， 只要在相 同效果的范围内， 都落入本本发明的保护范围。
