另外,下面结合附图描述的本发明的实施方式是示例性的,仅用于解释本发明的实施方式,而不能理解为对本发明的限制。
请参阅图1、图3和图4,本发明实施方式提供的一种分气结构100,包括第一腔体10和第二腔体20。
第一腔体10开设有第一腔室12。第一腔体10的底面间隔设置有第一导气管14和第二导气管16。第一导气管14连通第一腔室12。第一导气管14在第一腔室12的底面形成第一开口142。第二导气管16在第一腔室12的底面形成与第一开口142间隔的第二开口162。
第二腔体20设置在第一腔室12中。第二腔体20开设有第二腔室22。第二腔室22的底面开设有与第二腔室22相通的进气孔24。进气孔24与第二开口162连通。
第二腔体20的腔体底面23间隔覆盖在第一开口142的上方且设置有隔开第一开口142与第二开口162的挡壁30。
本发明实施方式中的分气结构100中,由第一导气管14出射的气体被第一腔体10的底面分散到第一腔室12的各个位置后向上扩散。如此,使得第一腔体10较均匀地向第一腔室12的各个位置供气,保证第一腔体10所形成的火焰均匀。同时,挡壁30可使第一腔室12和第二腔室22的供气相
互不影响。
进一步地,在某些实施方式中,分气结构100还能实现红蓝组合燃烧火焰。
具体地,请参阅图9,本发明实施方式中的第一腔室12相当于燃烧器200的中环燃气腔室,第二腔室22相当于燃烧器200的内环燃气腔室。设置在第二腔室22中的火盖为多孔陶瓷板2047。
如此,燃气在多孔陶瓷板2047上燃烧,使多孔陶瓷板2047变红,实现红外线煮食。气体在第一腔室12上的火盖处燃烧形成蓝色的中环火焰,从而巧妙地实现红蓝组合燃烧火焰,提高了燃烧性能和加热效率。
具体地,本发明实施方式中,第一腔体10和第二腔体20基本呈圆柱状。
如此,结构简单,易于制造。同时,便于气体进入第一腔室12和第二腔室22时更流畅,保证气体的流速,从而保证燃气在第一腔室12和第二腔室22上的火盖处燃烧的稳定性。
在一个例子中,第一腔体10和第二腔体20可采用铜制成。
如此,第一腔体10和第二腔体20能耐高温,延长分气结构100的使用寿命。同时,使得第一腔体10和第二腔体20易于铸造成型,形成第一开口142、第二开口162和进气孔24等结构,实现较佳的分气作用。
在某些实施方式中,挡壁30呈环形并向远离第二腔体20的方向凸出,进气孔24贯穿挡壁30。
如此,增加了进气孔24的长度,使得更多的气体能被收集进入到第二腔室22内,保证第二腔室22的供气量。
当然,挡壁30突出腔体底面23的距离可随第二腔室22的大小进行调整以使第二腔室22的供气量和气体速度更加优化。
在某些实施方式中,第一导气管14和第二导气管16为文丘里管。
在某些实施方式中,第一腔室12的底面上开设有凹槽122,凹槽122围绕第二开口162,凹槽122和挡壁30配合连接以隔开第一开口142与第
二开口162。
如此,第二腔体20和第一腔体10之间连接紧密,第一开口142和第二开口162被完全隔断,分气结构100的分气性能得到大幅提升,避免了分气结构100在高温环境中使用时间较长后,第一腔体10和第二腔体20发生形变导致连接不紧密从而影响分气性能的情况。
具体地,挡壁30***凹槽122中。
如此,分气结构100在高温环境中工作时,挡壁30受热膨胀,使得挡壁30与凹槽122的结合更加紧密,能较佳地阻止气体在第一腔室12和第二腔室22之间发生流通,保证了分气结构100的分气效果。
请一并参阅图2,在某些实施方式中,第一腔体10的外壁上设置有定位部18,用于安装分气结构100。定位部18包括导引部182和承靠部184,导引部182连接承靠部184,导引部182用于导引分气结构100的安装,导引部182凸出第一腔体10的外壁,且导引部182的高度由下到上逐渐增加。
在本发明实施方式中,第一腔体10相背两侧的每一侧都设置有间隔的两个定位部18。如此,分气结构100的安装较稳固,避免分气结构100在燃烧器200中的移位。
在某些实施方式中,进气孔24的孔壁包括导流面242,进气孔24中设置有遮挡片244,遮挡片244和导流面242相对间隔设置并与导流面242共同形成用于导引气体进入第二腔室22的导流通道246。
如此,气体沿导流通道246进入第二腔室22,大大提高了气体进入第二腔室22的气流速度和流畅度,使得气体在分气结构100外的燃烧更稳定。
具体地,分气结构100使用时,燃气与空气形成的混合气体喷向遮挡片244形成气流,遮挡片244将混合气体的方向转向导流通道246,混合气体经导流通道246进入第二腔室22内。
请参阅图5-图7,在某些实施方式中,导流通道246沿进气孔24的进气方向呈渐扩的形状。
如此,有助于气体更顺畅地通过导流通道246进入分气结构100的第二腔室22,同时也增加了气体的流速。
在某些实施方式中,导流面242呈弧形,遮挡片244包括顶面2442、底面2444和连接面2446,顶面2442和底面2444为平面,连接面2446连接顶面2442和底面2444,连接面2446呈弧形且与导流面242形成导流通道246。
如此,气体沿导流通道246进入第二腔室22时,弧形的导流面242能使气体受到的阻力减少,进而达到更快的速度。同时,弧形的导流面242使得气体流动更加平稳,避免了气体进入第二腔室22内后形成紊流或湍流,而出现影响燃气燃烧稳定性的情况。
具体地,导流面242和第二腔室22的底面的连接处为圆滑曲面。
如此,增加气体进入第二腔室22内的流畅性。
进一步地,导流面242还可设置为斜面。
如此,也能实现协助燃气顺畅进入第二腔室22内的目的。
较佳地,导流面242为斜面时,导流面242和第二腔室22的底面形成的锐角为45度。
如此,能进一步优化气体进入第二腔室22内的速度。
弧形的连接面2446则使气体冲击底面2444后,被直接转向,减少了气体的速度损失。连接面2446配合导流面242,形成供气体顺畅进入第二腔室22的导流通道246。
进一步地,本发明实施方式中连接面2446和导流面242之间的距离为0.5厘米-1.5厘米。
如此,气体经遮挡片244转向分散后通过导流通道246时,由于气流通道变窄,气体发生挤压,流速增加。同时,气体在导流通道246下方形成负压,吸取更多气体进入导流通道246,进一步增加了气体的流速。
在某些实施方式中,第二腔室22的底面23和顶面2442处于同一平面。
如此,使得气体从进气孔24进入第二腔室22后气体流动平稳、迅速,避免出现顶面2442和腔体底面23不在同一平面时气体进入第二腔室22后形成紊流的现象,进一步保证燃气从第二腔室22喷射后燃烧稳定。
在某些实施方式中,同一平面是指同一水平面。
在某些实施方式中,遮挡片244包括与进气孔24的孔壁连接的连接部2448,连接部2448上开设有多个通孔2441,通孔2441连通进气孔24和第二腔室22。
由于遮挡片244转向气体时,有小部分的气体被转向至连接部2448的方向,开设通孔2441能够将这部分气体导入到第二腔室22中,避免了气体流失,增加了第二腔室22的供气量。
具体地,本发明实施方式中,通孔2441有4个,且均匀设置在连接部2448上。
如此,提高了通孔2441分流的效果。
当然,通孔2441的个数不限于上述讨论的实施方式中的个数,而可以根据气体流量的大小和第二腔室22的大小进行调整,以达到较佳的分气效果。
在某些实施方式中,第二腔体20包括固定部26,固定部26连接遮挡片244和腔体底面23。
由于分气结构100在高温环境下工作,在高温环境下的遮挡片244容易发生形变,影响分气结构100的分气效果。固定部26进一步加固了遮挡片244,保证了遮挡片244稳定设置在第二腔体20上,不易发生形变,进而达到较佳的分气效果,提高了分气结构100的可靠度。
具体地,本发明实施方式中,固定部26呈三棱柱形。
如此,由于三角形的稳定性较强,固定部26能较佳地将遮挡片244稳定固定在第二腔体20上。
进一步地,固定部26还可以呈圆柱形。
如此,圆滑的固定部26表面不会对进入第二腔室22的气流产生影响,进一步提高气流在第二腔室22内的平稳性。
在某些实施方式中,第一开口142沿第一导气管14向第一腔室12的方向呈渐扩的形状,第二开口162沿第二导气管16向第一腔室12的方向呈渐扩的形状。
如此,有助于气体更顺畅地通过第一导气管14进入第一腔室12和通过第二导气管16进入第二腔室22,同时也增加了气体的流速,促进了气体在设置在第一腔体10和第二腔体20上的火盖处燃烧的稳定性。
在某些实施方式中,第二腔体20可拆卸地安装在第一腔室12中。
如此,易于将第二腔体20拆卸下来对第一腔体10和第二腔体20进行清洁,保持分气结构100的清洁。
在某些实施方式中,第二腔体20除了通过挡壁30和第一腔室12底面上的凹槽122配合来安装在第一腔体10中,还能通过在第二腔体20上设置定位件28,在第一腔室12的底面上开设定位孔,通过定位件28和定位孔11的配合将第一腔体10安装到第二腔体20中。
如此,第一腔体10能稳定安装在第二腔体20中。第一腔体10和第二腔体20之间不易发生相对滑落,从而保证分气结构100的分气性能。同时,也便于第二腔体20的安装和拆卸。
具体地,定位件28有4个,呈长方形的四个顶点分布在腔体底面23上。
在某些实施方式中,第二腔室22的内壁上设置有阶梯状的安装部222。安装部222用于安装火盖。
如此,火盖能较稳定地安装在分气结构100上,不会出现左右和向下的位移,以便分气结构100内的燃气在火盖处形成稳定的火焰。同时阶梯状的安装部222还能防止分气结构100内的燃气从安装部222和第二腔体20之间的缝隙泄露,影响加热效果。
在本发明实施方式中,第二腔体20的侧壁上设置有承放部21,承放部
21用于在安装分气结构100时使分气结构100放置更稳定。
在某些实施方式中,第一腔室12包括腔室壁124,腔室壁124的顶端126沿气体的出气方向呈渐扩的形状。
如此,有助于气体更顺畅地从第一腔室12进入设置在第一腔室12上的火盖,同时也增加了气体的流速,促进了气体在设置在第一腔体10上的火盖处燃烧的稳定性。
具体地,腔室壁124的顶端126沿气体的出气方向呈斜面。
较佳地,腔室壁124的顶端126和水平方向形成的锐角为45度。
如此,能进一步优化气体从第一腔室12进入设置在第一腔室12上的火盖的畅通性和速度。
请参阅图8和图9,本发明实施方式的一种燃烧器200,包括如上任一实施方式的分气结构100。
本发明实施方式中的燃烧器200中,由第一导气管14出射的气体被第一腔体10的底面分散到第一腔室12的各个位置后向上扩散。如此,使得第一腔体10较均匀地向第一腔室12的各个位置供气,保证第一腔体10所形成的火焰均匀。同时,挡壁30可使第一腔室12和第二腔室22的供气相互不影响。
具体地,在某些实施方式中,在分气结构100应用到燃烧器200时,分气结构100可作为燃烧器200中环和内环的分气结构100。第二腔室22内可放置多孔陶瓷板2047,从分气结构100向外喷射的燃气在多孔陶瓷板2047处燃烧,加热多孔陶瓷板2047,形成红外线煮食,实现了极小火、炭火慢炖等功能。
本发明实施方式的燃烧器200还包括底座202和上进风结构204。
底座202内形成有燃气进气间2022,底座202底部设置有燃气进气通道2026,底座202上设置有接液盘2024,底座202和接液盘2024间隔设置形成第一空气补充通道206。上进风结构204内开设有第二空气补充通道
208。上进风结构204上还设置有两个第三导气管2042。第三导气管2042伸入燃气进气间2022内。
上进风结构204上设置有燃气腔室。在本发明实施方式中,上进风结构204上的燃气腔室相当于外环燃气腔室2044。外环燃气腔室2044上安装有外环火盖2046。分气结构100中的第一腔室12相当于中环燃气腔室,第一导气管14和第二导气管16伸入燃气进气间2022,第一腔室12上安装有中环火盖2043。第一腔室12内的第二腔室22相当于内环燃气腔室。第二腔室22内安装有多孔陶瓷板2047。
本发明实施方式的燃烧器200工作时,燃气从燃气进气通道2026输入,通过设置在燃气进气通道2026上的喷嘴2028喷入燃气进气间2022,喷入的燃气在燃气进气间2022产生负压以从第一空气补充通道206吸入一次空气A,如图8所示,一次空气与燃气在燃气进气间2022预混形成混合气体并共同经过上进风结构204。一部分混合气体经第三导气管2042的导引进入外环燃气腔室2044,如A1所示,经外环火盖2046向外喷射、燃烧形成外环火。
在燃气进气间2022内的燃气与空气的另一部分混合气体(如图8中线路A2所示)经第一导气管14和第二导气管16的导引分别进入第一腔室12和第二腔室22,第一腔室12的混合气体经中环火盖2043向外喷射,燃烧形成中环火。进入第一腔室12的混合气体的流动方向可参虚线A21所示。
第二腔室22中的混合气体经多孔陶瓷板2047向外喷射,燃烧形成红外线的内环火。进入第二腔室22的混合气体的流动方向可参虚线A22所示。
第二空气补充通道208可对中环火盖2043和多孔陶瓷板2047处的燃气燃烧时补充二次空气,和/或对外环火盖2046内侧的燃气燃烧时补充二次空气,二次空气经第二空气补充通道208进入燃烧器200内部并向上流动,进而实现补充二次空气。二次空气进入燃烧器200的气体的流动方向如图中带箭头的虚线B所示。
如此,燃烧器200通过第三导气管2042、第一导气管14和第二导气管16分气,实现了三环火的燃烧器200,提高了燃烧器200的加热效率。
