Abstract

一种半封闭式燃烧的燃气灶，使液化气在锅和热反射板之间进行半封闭式燃烧，燃烧后的废气由热反射板上部的过气孔进入环形废气室，然后由排烟道排出室外，从而减少燃烧热量的流失，控制了燃烧废气的扩散，提高了燃烧热效率，减少废气对厨房的污染，降低了夏天厨房的温度。

Description

半封闭式燃烧的燃气灶
涉及领域
本实用新型涉及到液化气燃气灶的技术，它是使液化气火焰在一个半封闭的燃烧室里燃烧的燃气灶。
背景技术
现在的燃气灶都是敞开式燃烧，这样燃烧后产生的温度较高的废气都散发在厨房里，这些废气造成厨房的污染，尤其是在夏天使得厨房温度很高，影响人的健康，使人感到难受。
发明内容
本技术是在图1中燃气灶的锅(3)和火焰的外围加装一环形曲面热反射板(2)，这样火焰就在热反射板和锅之间所形成的燃烧室里燃烧，火焰在锅的上部边缘处成为废气，热反射板上部与锅相连接处的圆周开有多个过气孔(5)，在热反射板上部过气孔的外面是一环形废气室(4)，废气室又与排烟道(6)相连，燃烧废气由过气孔进入废气室，然后再由排烟道排到室外。这样能减少热量的流失，热反射板能把部分热量反射到锅上去。
有益效果
本装置能有效地将燃烧热废气控制起来，集中排出室外，减少对厨房的污染，降低厨房的温度，提高燃烧热效率。
附图说明：
图1：是本实用新型整体结构示意图
图2：是在图1上去掉灶头和锅后所见过气孔分布情况示意图
图中1、液化气灶头  2、热反射板  3、锅
    4、环形废气室  5、过气孔    6、排烟道  7、叶门阀
具体实施方法
如图1热反射板(2)与锅(3)的间隙上部小下部大，下部的间隙要保证有足够的空气能进入燃烧室，使燃烧充分。为了使燃烧室火焰四周燃烧均匀，热反射板上边缘的过气孔(5)呈圆周分布，排烟道处的孔距大于圆周对面的孔距，以平衡四周气流的阻力，如图2所示。过气孔把燃烧室和环形废气室(4)连通起来，环形废气室(4)主要是把废气控制，集中由排烟道(6)排出室外，排烟道上装有叶门阀(7)，安装时调节好叶门阀，控制排烟道的负压，保证废气流不能过快，燃烧自然。
