Abstract

火焰型式可变的节能燃气灶,其特征是:由燃烧器、气阀、喷气嘴组成,每一燃烧器分互不相通的环状燃烧器及中央的柱状燃烧器两部分。柱状燃烧器的气孔分布在其顶盖直径不大于20mm的圆内。环状燃烧器的气孔均匀分布在其气道盖顶端和内外侧。在燃烧器气阀和两喷气嘴之间设置一个三通气阀。通过分别或同时向环状和柱状燃烧器供气,产生集中或分散型火焰。本实用新型的有益效果是:既可产生高效的集中型火焰以节气,又可产生分散型火焰以满足不同的使用需要。

Description

火焰型式可变的节能燃气灶
所属技术领域
本实用新型涉及燃气灶,特别是一种节能燃气灶。
背景技术
市售家用燃气灶,其燃烧器均产生面积较大、各处火力较均匀的分散型火焰。而我们知道,集中于锅底中心的集中型火焰,由于其向外周扩散时经过的锅底面积---热交换面积较大,故热效率比分散型的高20%--40%。而在蒸煮炖炸炒等大部分情况下,都可用集中型火焰。显然,只能产生分散型火焰的市售燃气灶始终工作在低效率状态,造成能源的巨大浪费。
发明内容
为解决现在市售燃气灶只能产生单一的低效分散型火焰的不足,本实用新型提供一种高效的节能燃气灶。
本实用新型解决其技术问题所采取的技术方案是:火焰型式可变的节能燃气灶,其特征是:由燃烧器、气阀、喷气嘴组成,每一燃烧器分互不相通的环状燃烧器及中央的柱状燃烧器两部分。柱状燃烧器的气孔分布在其顶盖直径不大于20mm的圆内。环状燃烧器的气孔均匀分布在其气道盖顶端和内外侧。在燃烧器气阀和两喷气嘴之间设置一个三通气阀。通过分别或同时向环状和柱状燃烧器供气,产生集中或分散型火焰。
本实用新型的有益效果是:既可产生高效的集中型火焰以节气,又可产生分散型火焰以满足不同的使用需要。
附图说明
图1是燃烧器及供气系统平面示意图。图2是A-A剖面图。图3是B-B剖面图。
具体实施方式
如图所示,燃烧器5中间是柱状燃烧器6,其气孔10分布在顶盖7上直径不大于20mm的圆内,产生面积小而密集的集中型火焰。环绕其外的是燃烧器8,气道盖11上有均匀分布在顶端和内外侧的气孔9,产生分布面积大而均匀的分散型火焰。燃气灶气阀1和喷嘴3、4之间设置一个三通气阀2。此阀可将进气分别或同时供给两喷嘴。上下贯通的空隙12的作用是补充空气助燃。当三通气阀的手柄扳至k1位时,气体全部经喷嘴3进入燃烧器8,产生分散型火焰;手柄扳至k2位时气体全部经喷嘴4进入燃烧器6,产生集中型火焰。而当手柄在k1、k2之间时,火焰分布介于两者之间。火焰大小均由燃气灶开关1控制。
