本实用新型涉及燃气灶， 具体的说， 是涉及一种喷气式燃气灶。
说
背景技术
燃气灶是现代社会常见的生产、 生活用具。 燃气灶有很多种类， 有 使用液化石油气作为发热能源的燃气灶，书也有使用煤气、 天然气或沼气 等可燃烧气体作为发热能源的燃气灶。
传统的燃气灶， 其燃烧系统的基本结构是， 将可燃气体喷射到铸铁 的灶头， 在灶头上加分火盖， 可燃气体在铸铁灶头的分火盖上燃烧后， 所产生的热量传递到加工食物用的锅底。 这种燃烧系统结构有两个缺 陷， 一是， 燃气在分火盖上燃烧时， 完全依赖于周围空气中的氧气， 即 燃气未事先与氧气混合充分就开始燃烧， 这将导致燃气不能充分燃烧， 从而造成能源的浪费和燃气中有害气体的超标排放； 二是， 这里的燃气 燃烧是一种火苗燃烧， 燃气燃烧所产生热量的利用， 取决于锅与火苗间 的自然接触距离， 热交换效率极低。
中国专利申请号为 200720120452.9的实用新型专利申请， 公开了一 种喷气式燃气灶。 其结构特点之一是， 燃气在燃烧前， 在一个中空柱体 内先行与空气混合，使得最终燃烧的气体是一种混合气体。这种燃气灶， 其燃气的利用率比上述传统的燃气灶提高了很多， 有害气体的排放也因 此有所降低； 其结构特点之二是， 设置火焰控制盖， 使得混合气体在火 焰控制盖之上附着在锅底燃烧， 从而减少了热能的传递损耗， 提高了热 交换效率。 然而， 这种喷气式燃气灶， 其燃气与空气的预混合， 是一种 在一个中空柱体空间内的自然混合， 混合的程度并不高， 混合的效果一 般， 从而导致燃气还是不能完全充分的燃烧； 另外， 不论是瓶装燃气还 是管道燃气，其喷出压力是有限的，这种喷气式燃气灶设置火焰控制盖， 依靠燃气的喷出压力使得混合气体在火焰控制盖之上燃烧， 其效果也是 有限的， 热交换效率的提升并不明显。 发明内容
本实用新型的目的在于解决现有技术的燃气灶燃气不能充分燃烧， 有害气体排放超标， 热交换利用效率不佳等问题， 而提供一种新型的喷 气式燃气灶。
本实用新型是这样实现的， 一种喷气式燃气灶， 包括了底端设置有 网状通孔的中空柱状的灶头， 设置在灶头顶端的火焰控制盖， 以及连接 灶头底端的燃气管， 其特征在于， 在所述灶头的中空腔室内还设置有气 流扰动混合器。
优选实施方式是， 所述灶头的中空腔室呈圆柱状； 所述气流扰动混 合器是一种圆柱罩状体， 包括了第一混合器和第二混合器， 所述第一混 合器设置在第二混合器的圆柱罩体内腔； 所述混合器圆柱罩的外立面四 周设置有贯通圆柱罩上下柱面的斜槽， 斜槽内开设有贯通圆柱罩罩壁的 气孔。
优选实施方式是， 所述燃气管连接灶头底端的部分设置有减压分流 装置。
优选实施方式是， 在所述灶头的下端， 还设置有鼓风室； 所述燃气 管穿过鼓风室接入灶头的底端， 所述鼓风室的上端四周密闭连接灶头的 底端， 所述鼓风室的壁上还设置有连接鼓风装置的通孔。
优选实施方式是， 在所述灶头的中空腔室内部， 还设置了带有网状 通孔的隔板， 所述隔板将灶头的中空腔室分隔成上下的第一混合室和第 二混合室， 所述气流扰动混合器设置在第一混合室中。
优选实施方式是， 在所述灶头的下端， 还设置有鼓风室； 所述燃气 管接入鼓风室内， 所述鼓风室的上端四周密闭连接灶头的底端， 所述鼓 风室的壁上还设置有连接鼓风装置的通孔。
优选实施方式是， 在所述灶头的中空腔室内部， 还设置了带有网状 通孔的隔板； 所述隔板将灶头的中空腔室分隔成上下的第一混合室和第 二混合室， 所述气流扰动混合器设置在第一混合室中； 在所述灶头的旁 边， 还设置有密闭的鼓风室； 所述鼓风室与所述第二混合室之间以管道 连通； 所述燃气管接入鼓风室内， 所述鼓风室的壁上还设置有连接鼓风 装置的通孔。
实施本实用新型的喷气式燃气灶， 由于在灶头的中空腔室内设置了 气流扰动混合气， 使得燃气在燃烧前， 被强制的与空气扰动混合， 混合 非常充分，从而使得燃气能够完全充分的燃烧，将少了有害气体的排放， 也节约了燃气； 在灶头的下端设置鼓风室， 通过鼓风装置主动的给燃气 混合室中鼓风， 一方面增加了氧气的供给， 并使得空气与燃气的混合更 加充分， 另一方面， 也增加了混合气体从火焰控制盖喷出的压力， 可以 使得混合气体在火焰控制盖之上紧贴着锅底燃烧， 其热能利用效率有了 很大的提升； 在灶头的中空腔室中设置隔板， 由第一混合室完成空气与 燃气的第一次混合， 再在第二混合室中由气流扰动混合器完成空气与燃 气混合气的进一步强制混合， 其混合程度非常高， 从而燃气燃烧更加充 分， 能源的利用效率得以进一歩的提升。 附图说明

下面， 结合附图和实施例对本实用新型的喷气式燃气灶作进一步的 详细说明。
如图 1所示， 本实用新型的喷气式燃气灶， 包括了呈中空柱状的灶 头 1， 灶头的中空腔室， 是作为燃气在燃烧前， 与空气的进行混合的混 合室。 灶头的底端， 设置有网状的通孔 11 (如图 2所示）， 这些通孔在 本实施例中， 是空气进入灶头的中空腔室 （燃气与空气的混合室） 的通 道； 在灶头的顶端设置有火焰控制盖 2， 火焰控制盖上设置有通孔与灶 头中空腔室相连通； 火焰控制盖与灶头可以是一体化的， 即通过一个模 具一次成型制造出来； 也可以是分体式的， 即火焰控制盖通过卡口或螺 紋等， 连接在灶头上。 燃气管 3连接在灶头的底端， 气流扰动混合器 4 设置在灶头的中空腔室内。 设置气流扰动混合器， 使得燃气在燃烧前， 被强制的与空气扰动混合。 如图 3至图 5所示， 气流扰动混合器可以有 各种各样的形状， 其基本结构都是： 将燃气管喷射出的燃气在气流扰动 混合器的中空腔室内与空气进行混合， 然后由设置在其四周的与中空腔 室连通的通孔释放出混合气体。 由于混合器的阻滞扰动， 使得燃气与空 气的混合效果非常好， 混合气体能够完全充分的燃烧， 这将减少有害气 体的排放， 也能够节约了燃气能源。
本实用新型的一个优选实施方式是， 灶头的中空腔室是呈圆柱状的， 气流扰动混合器是圆柱罩状体。 在实际实施本实用新型的喷气式燃气灶 时， 可将气流扰动混合器的大小制作的与灶头的中空腔室相匹配。 如图
6所示， 所述气流扰动混合器包括了第一混合器和第二混合器， 均为圆 柱罩状体；第一混合器 4A设置在第二混合器 4B的圆柱罩体内腔；如图 7、 图 8、 图 9和图 10所示， 混合器圆柱罩的外立面四周设置有贯通圆 柱罩上下柱面的斜槽 41， 斜槽内开设有贯通圆柱罩罩壁的气孔 42。 贝 lj， 第一混合器 4A圆柱罩的中空内腔， 构成了燃气与空气的混合空间； 当 燃气管喷射出的燃气进入圆柱罩的中空内腔时， 受到混合器的阻滞， 在 与空气初步混合后， 借助燃气的压力， 由气孔 42喷射向第一混合器 4A 的外部； 由于气孔 42是开设在斜槽 41内的， 当初歩混合的燃气空气混 合气体喷射出第一混合器 4A外时， 受到斜槽的扰动， 混合气体的气流 将沿斜槽向上喷射；由于第一混合器 4A被容纳在第二混合器 4B的中空 内腔中， 来自第一混合器 4A的斜槽的混合气体， 将借助燃气的压力， 由第二混合器 4B的气孔喷射向第二混合器 4B的外部，并进一步的受到 第二混合器 4B的斜槽的扰动，混合气体的气流将沿第二混合器 4B的斜 槽向上喷射； 而由第一混合器 4A和第二混合器 4B组合所成的混合器， 是设置在灶头的中空腔室内， 腔室中有空气存在， 这将导致混合气体在 斜槽内进一步的与空气混合， 混合的程度得以进一步的提升。 采用这种 气流扰动混合器的优选实施方式， 可以使得燃气更加充分的燃烧， 更能 节约燃气。 显而易见的， 本优选实施方式中， 采用了两个混合器 （第一 混合器 4A和第二混合器 4B)来组合实现燃气与空气的充分混合， 如果 采用三个或更多个的混合器， 来组合实现燃气与空气的充分混合， 其实 现原理是类似的， 此处不再赘述。
本实用新型的又一个优选实施方式是， 所述燃气管连接灶头底端的 部分设置有减压分流装置。 减压分流装置可以有各种各样的技术方案， 其基本的原理是， 使得高压的燃气不致沿着燃气管的方向直接喷射， 而 代之以改变喷射方向且分成多股的， 由多个分流孔喷射出来。 如图 11 所示， 本优选实施方式的一种减压分流装置， 燃气从燃气管 3喷射上来 时， 由多个分流孔 31 改变喷射方向后喷射出来， 其外观结构可参见图 12或图 13。 贝 I」， 一方面， 燃气的压力有所舒缓， 另一方面， 燃气与空 气的混合将为更加充分。
本实用新型的又一个优选实施方式是，如图 12所示，在灶头的下端， 还设置有鼓风室 5; 在此实施方式中， 燃气管 3是穿过鼓风室 5接入灶 头底端的； 鼓风室的上端四周密闭连接灶头的底端， 鼓风室与灶头混合 室之间由图 2所示的灶头底端的网状通孔 11所连通；鼓风室的壁上设置 有连接鼓风装置的通孔 51。这里的鼓风装置， 可以是使用直流电或交流 电的鼓风机、 风扇等。 在灶头的下端设置专门的鼓风室， 通过鼓风装置 主动给灶头中的燃气混合室鼓风， 一方面使得空气与燃气在气流扰动混 合器的阻滞扰动作用下混合得更加充分， 另一方面， 也增加了混合气体 从火焰控制盖喷出的压力， 可以使得混合气体在火焰控制盖之上紧贴着 锅底燃烧， 实现了强化传热， 其热能利用效率有了很大的提升， 同时， 也增加了氧气的供给， 燃气燃烧将更加充分。
本实用新型的再一个优选实施方式是， 如图 13所示， 在灶头的中空 腔室内部， 还设置了带有网状通孔的隔板 6 (隔板的结构如图 2所示）， 隔板将灶头的中空腔室分隔成上下的第一混合室 61和第二混合室 62， 气流扰动混合器 4设置在第一混合室 61中。 在本优选实施方式中， 显 而易见的， 第二混合室成为了鼓风室鼓入的空气与燃气管喷射出的燃气 的第一次混合的混合空间； 经第一次混合后的混合气体通过隔板 6的网 状通孔喷射入第一混合室， 即发生如上面实施例所描述的， 在气流扰动 混合器的作用下， 进一步的进行混合的过程， 此处不再赘述。 显然， 这 种优选实施方式， 将使得燃气与空气的混合程度得以进一歩的提升， 其 有益效果将比上述实施例更加明显。
本实用新型的又一个优选实施方式是， 如图 14和图 15所示， 在所 述灶头的下端， 还设置有鼓风室 5; 所述燃气管 3接入鼓风室 5内， 鼓 风室的上端四周密闭连接灶头的底端， 鼓风室与灶头混合室之间由图 2 所示的网状通孔 11所连通（如图 15所示），所述鼓风室的壁上还设置有 连接鼓风装置的通孔 51。这里的鼓风装置， 可以是使用直流电或交流电 的鼓风机、 风扇等。 在灶头的下端设置专门的鼓风室， 通过鼓风装置主 动给灶头中的燃气混合室鼓风， 一方面使得空气与燃气首先在鼓风室中 进行第一次的混合， 并在气流扰动混合器的阻滞扰动作用下混合得更加 充分， 另一方面， 也增加了混合气体从火焰控制盖喷出的压力， 可以使 得混合气体在火焰控制盖之上紧贴着锅底燃烧， 实现了强化传热， 其热 能利用效率有了很大的提升， 同时， 也增加了氧气的供给， 燃气燃烧将 更加充分。
本实用新型的再一种优选实施方式是， 请参考图 13所示， 在所述灶 头的中空腔室内部， 还设置了带有网状通孔的隔板； 所述隔板将灶头的 中空腔室分隔成上下的第一混合室和第二混合室， 所述气流扰动混合器 设置在第一混合室中； 如图 16所示， 在所述灶头的旁边， 还设置有密 闭的鼓风室 5; 所述鼓风室 5与所述第二混合室 （如图 13所示之 62) 之间以管道 7连通； 所述燃气管 3接入鼓风室内， 所述鼓风室的壁上还 设置有连接鼓风装置的通孔 51。在本优选实施方式中， 显而易见的， 空 气与燃气将首先在鼓风室中进行第一次的初歩混合， 而第二混合室成为 了鼓风室鼓入的空气与燃气的混合气体再次混合的混合空间； 经前述两 次混合后的混合气体再通过隔板的网状通孔喷射入第一混合室， 即发生 如上面实施例所描述的， 在气流扰动混合器的作用下， 进一步的进行混 合的过程， 此处不再赘述。 显然， 这种优选实施方式， 将使得燃气与空 气的混合程度得以更进一歩的提升， 其有益效果将比上述实施例更加明 显。
总之， 上述实施例所描述的几种实施方式， 并不代表本实用新型所 有的实现方式； 以上实施例不是对本实用新型的具体限定， 所有与本实 用新型技术方案相类似的构造， 都应属于本实用新型的保护范围。
