具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点,下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述的其他方式来实施,因此,本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图10描述根据本申请一些实施例提出的燃烧器和燃气灶。
实施例一:
如图1至图4所示,本申请的第一个实施例提供了一种燃烧器1,包括:第一出火组件200、第二出火组件300和扰流结构400;第一出火组件200包括第一出火件210,第二出火组件300包括第二出火件310。
其中,第一出火组件200设于第二出火组件300的周侧,第一出火件210和第二出火件310能够形成内外两环火焰,可从不同位置对烹饪器具进行加热。扰流结构400设置于第一出火组件200和第二出火组件300之间,扰流结构400被配置为能够改变第一出火件210和第二出火件310的部分出火方向。
具体地,扰流结构400能够改变第一出火件210的部分出火方向,使第一出火件210的火焰向靠近第二出火件310的方向进行聚拢,进而使燃烧器1的火焰分布更加集中,加热效率更高。扰流结构400还能够改变第二出火件310的部分出火方向,使第二出火件310的火焰向靠近第一出火件210的方向进行扩散,进而使燃烧器1的火焰分布范围更广,使烹饪器具受热更加均匀。
也即,本实施例提供的燃烧器1通过设置扰流结构400来改变第一出火件210和第二出火件310的部分出火方向,实现了燃烧器1火力分布集中度的调整,进而满足了多种不同烹饪场景的用火需求。
实施例二:
如图4所示,根据本申请的一个实施例,在上述实施例的基础上,进 一步地,扰流结构400包括导流腔410,其中,导流腔410包括进气部412和出气部414。
具体地,导流腔410包括进气部412和出气部414,用于扰流的气体通过进气部412进入导流腔410,经导流后的气体通过出气部414流出导流腔410。出气部414位于第一出火件210和第二出火件310之间,进而使得流出导流腔410的气体可对第一出火件210和第二出火件310产生的火焰进行扰动,以改变第一出火件210和第二出火件310的部分出火方向,进而改变燃烧器1的火力分布。
进一步地,如图4和图6所示,扰流结构400还包括第三分流板440和第三分流孔450。其中,第三分流孔450设置于第三分流板440,第三分流板440设置于导流腔410,位于进气部412处。当用于扰流的气体通过进气部412进入导流腔410内时,会被位于进气部412处的第三分流板440分流,使气体能够均匀地分布于导流腔410内。且多个第三分流孔450沿第三分流板440均匀分布,进一步提升了分流效果,提升了导流腔410内气体分布的均匀性,从导流腔410中喷出的射流分布更加均匀,进而使第一出火件210和第二出火件310的各处火焰受到的扰动效果更加均匀,提升了烹饪器具受热的均匀性。
进一步地,如图3和图4所示,扰流结构400还包括导流部420,导流部420设置于导流腔410,导流部420由进气部412向出气部414延伸;其中,导流部420的数量为多个,多个导流部420沿导流腔410的周向间隔分布,且多个导流部420呈螺旋状分布。
具体地,扰流结构400还包括导流部420,导流部420设置于导流腔410,导流部420可对进入导流腔410内的气体进行导流。导流部420由进气部412向出气部414延伸,气体经进气口进入导流腔410后,沿导流部420的延伸方向流向出气部414。通过设置多个导流部420,提升了气体的导流效果,多个导流部420沿导流腔410的周向间隔分布,且多个导流部420呈螺旋状分布,导流后的气体形成旋转射流,旋转射流通过出气部414从导流腔410流出,进而对第一出火件210和第二出火件310的火焰进行卷吸。
一方面,第一出火件210的火焰在旋转射流卷吸作用下,向靠近第二出火件310的方向聚拢,从而提升了火焰集中度。同时,旋转射流增大了烹饪器具与第一出火件210之间的高温烟气的流动速度,加强了高温烟气与烹饪器具对流换热的效果,从而进一步提升了加热效率。此外,旋转射流还能起到提供更多空气的作用,以使第一出火件210中的燃气能够充分燃烧,提升了加热效果,并降低了一氧化碳的排放量,使整个烹饪环境更加安全。
另一方面,在单独使用第二出火件310对烹饪器具进行加热时,第二出火件310的火焰在旋转射流卷吸作用下,向靠近第一出火件210的方向扩散,从而增大了第二出火件310的火焰分布范围,进而使烹饪器具受热更加均匀。

实施例十一:
本申请的具体实施例提供了一种火力集中度可调的大气式燃气灶,燃气灶包括:风机和燃烧器1。
其中,如图1至图10所示,燃烧器1包括第一出火组件200、第二出火组件300和扰流结构400。第一出火组件200包括第一盖体230和第一分火器220,第二出火组件300包括第二盖体330和第二分火器320,扰流结构400包括导流腔410、导流部420和盖体430。
导流部420设置于盖体430上,如图3所示,导流部420为设置于盖体430上的导流片结构,且导流片沿盖体430的周侧呈螺旋状分布,进而实现了对出气方向的改变。
第二盖体330的外壁面上设有多个第二火孔312和多个第二稳焰孔314。盖体430上设置有第一传火缝512和导流腔410的出气部414,导流部420设置于导流腔410内。第一盖体230上设有多个第一火孔212、多个第一稳焰孔214和第二传火缝522。
其中,多个第一火孔212位于第一盖体230的周侧,任一第一火孔212的中心线相对于重力方向倾斜设置,从第一火孔212排出的燃气具备沿第一盖体230的径向和垂直于水平面向上的两个方向的分速度,实现对烹饪器具加热的同时扩大了第一出火件210的火焰范围。多个第一稳焰孔214位于第一盖体230的周侧或第一分火器220的周侧,第一稳焰孔214的过流面积小于第一火孔212的过流面积,通过设置第一稳焰孔214,使第一进气腔体240中的燃气燃烧更加充分,提升了加热效率的同时降低了一氧化碳的排放,并可防止燃气燃烧速度较低或高负荷燃烧时产生离焰或脱火现象,保持第一出火件210的火焰稳定燃烧。
同样的,第二火孔312的中心线相对于重力方向倾斜设置,第二稳焰孔314的过流面积小于第二火孔312的过流面积。
第二分火器320内设有环形的第二分流板350,第二分火器320底部设有第二进口322。第一分火器220底部设有第一进口222和导流腔410的进气部412。其中,第一进口222处设有第一分流板250,进气部412处设有第三分流板440。
当燃气与空气的混合气体通过第一进口222进入第一进气腔体240时,会先被位于第一进口222处的第一分流板250分流,使混合气体能够均匀地分布于第一进气腔体240内,进而提升了第一出火件210的火焰也即外环火焰的分布均匀性,使烹饪器具受热更加均匀。同理,通过设置第二分流板可提升内环火焰的分布均匀性。此外,当用于扰流的气体通过进气部412进入导流腔410内时,会被位于进气部412处的第三分流板440分流,使气体能够均匀地分布于导流腔410内,使从导流腔410中喷出的射流分布更加均匀,进而使第一出火件210和第二出火件310的各处火焰受到的扰动效果更加均匀,进一步提升了烹饪器具受热的均匀性。
燃烧器1各部件的装配关系如下:如图4所示,第二盖体330设置于第二分火器320上方,第二盖体330和第二分火器320围合成第二进气腔体340。第一盖体230设置于第一分火器220上方,第一盖体230和第一分火器220围合成第一进气腔体240。盖体430设置于第一盖体230和第二分火器320上方,盖体430与第一盖体230、第一分火器220围合出导流腔410。如图3和图7所示,盖体430上的第一传火缝512和第一盖体230上的第二传火缝522对齐,以连通第一传火缝512和第二传火缝522,形成传火通道500。在导流部420所在的位置,盖体430和第一盖体230之间构成环形射流狭缝,出气部414为环形槽。
燃气与一次空气的混合气分别由第一进口222和第二进口322进入第一分火器220和第二分火器320。混合气在经环形的第一分流板250和第二分流板350分流后分别流入第一进气腔体240和第二进气腔体340。随后混合气分别经由位于第二盖体330和第一盖体230上的第二火孔312、第二稳焰孔314、第一火孔212与第一稳焰孔214排出并被点燃发生燃烧,形成内外两环火焰,分别为内环火焰和外环火焰。当燃烧器1上部放置烹饪器皿时,内环火焰和外环火焰的高温燃气运动速度有两个分量,一个速度分量为沿燃烧器1的半径方向向外的速度分量,另一个为垂直于水平面向上的速度分量。在两个速度分量的共同作用下,高温燃气向烹饪器皿底面运动并与之发生换热进而实现加热功能。
如图2至图4所示,第一盖体230为直流火盖,因此在大热负荷工况 下,其火焰范围较广,火力集中度较低。此时,若需要将火力集中度增高则需开启射流,加压空气由进气部412进入并经第三分流板440分流后流入导流腔410。随后,加压空气在导流部420的导流下形成环状旋转射流从出气部414喷出。外环火焰在这股环状旋转射流的卷吸作用下向中心聚拢,从而提升火力集中度。同时,环状旋转射流诱发的旋转流场增大了锅底附近高温烟气的周向运动速度,加强了高温烟气与锅底的对流换热,有利于热效率的提升,适用于爆炒、高温煎炸等火力集中度需求高的烹饪场景。此外,这股环状旋转射流还能起到主动供给二次空气的作用,缓解大热负荷下二次风供给不足的问题,提升燃烧效率,降低一氧化碳的排放,使整个烹饪环境更加安全。
在小热负荷工况下外环火焰熄灭,只有内环火焰维持燃烧,其火焰范围较小,火力集中于锅底中心。此时,若需要将火力集中度降低,使加热更为均匀,则需开启射流。类似地,从进气部412流入导流腔410的加压空气会在导流部420的导流下形成环状旋转射流,环状旋转射流从出气部414喷出。内环火焰在这股环状旋转射流的卷吸作用下向四周发散,加热面积增大,火力集中度降低,加热均匀性更好。在小热负荷的烹饪环境下,如小火煎、焖或煲汤时,较广的火力分布能够使食物更均匀受热、汤汁更均匀的沸腾,锅底中心不易糊锅。
从环形射流狭缝排出的气流为环形气流,能够对第一出火件210和第二出火件310输出的环形火焰的各个位置进行均匀的卷吸,进而使第一出火件210的各处火焰能够同步且均匀地向内聚拢,第二出火件310的各处火焰能够同步且均匀地向外扩散,改善了卷吸效果。

在该实施例中,燃气灶还包括旋钮,旋钮与射流发生器202相连接,通过旋钮的旋转可以实现对射流发生器202的矢量控制,进而实现了对第一出火部102和第二出火部104的火焰角度的无极调整,也即射流部204的合成射流的强弱会对第一出火部102和第二出火部104的火焰的偏转效果起到作用,通过控制射流发生器202,所产生合成射流的强弱会随之变化,火焰的角度偏转也随之变化。由于合成射流多用信号控制,通过旋钮的电控能实现火焰角度的无级变化。
本申请的一个具体实施例中提供了如图21至图26所示的燃烧器1,具体在内外火环之间添加合成射流,利用合成射流对主流的动量偏转控制特性,对内外火环出口火焰的角度进行控制。
该实施例提供的燃烧器1包含第二火盖120、射流盖体212、射流座体214、射流分流器210、第一火盖116、第一座体118、燃气分流器114、安装座124、第二进气件112、第一进气件110、第二进气管128、射流发生器202、第一进气管126。装配好的燃烧器1的外观图,如图21和图22所示。其中,第二火盖120外壁面上设置内焰主火孔与内焰稳焰火孔,第一火盖116外壁面上设置外焰主火孔与外焰稳焰火孔;第二进气件112上设置内燃气入口,第一进气件110上设置外燃气入口;燃气分流器114上设置外燃气分流出口,第一座体118上设置外燃气外火盖入口;射流分流器210上设置射流分流出口,射流座体214上设置射流座体214射流入口; 分流流道结构具体视图如图27和图28所示。安装座124有三环,最里面为内燃气通道,最外面为外燃气通道,中间一环为合成射流通道。各部件的装配关系如下:
1.第二火盖120置于安装座124上方,第二进气管128与第二进气件112相连,安装座124设置于第二进气件112上方,从而形成完整的内燃气流道
2.第一火盖116置于第一座体118上方,两者配合形成外燃气腔室;燃气分流器114的外燃气分流出口与第一座体118的外燃气外火盖入口相配合,且燃气分流器114置于安装座124上方;第一进气管126与第一进气件110相连,且两者置于安装座124下方,从而形成完整的外燃气流道;
3.射流盖体212置于射流座体214上方,射流座体214与第一火盖116相配合,三者配合形成合成射流腔206室,射流盖体212与第一火盖116之间的狭缝作为射流部204;射流分流器210的射流分流出口与射流座体214的射流入口相配合,且射流分流器210置于安装座124上方;第一进气件110与第二进气件112两者都置于安装座124下方,两者间的间隙构成过流腔208,第一进气件110下方与射流发生器202相连,从而形成完整的合成射流流道。
燃气与一次空气的混合气分别由第二进气管和第一进气管进入第二进气件112和第一进气件110。混合气通过安装座124分别进入第二火盖120和燃气分流器114。混合气通过第二火盖120上的内焰主火孔与内焰稳焰火孔排出并被点燃燃烧,形成内环火。混合气通过外燃气分流器114进入第一火盖116和第一座体118构成的外燃气腔室,通过外焰主火孔与外焰稳焰火孔排出并被点燃燃烧,形成外环火。当炉头上部放置烹饪器皿时,内环火焰和外环火焰的高温燃气运动速度有两个分量,一个速度分量为沿半径方向向外,另一个方向为垂直于水平面向上。在两个速度分量的共同作用下,高温燃气向烹饪器皿底面运动并与之发生换热实现加热功能。现有技术中,由于内焰主火孔和外焰主火孔的结构限制,火焰只能呈现固定的角度加热锅底。
该实施例中,若需要控制火焰的角度,在火力不变的情况下改变锅底 的受热面积,适应各种炒菜需求,则打开射流发生器202,通过合成射流流道:第一进气件110与第二进气件112间隙、安装座124的中间环、射流分流器210进入射流腔206,之后通过射流部204与灶头上方气流进行相互作用。合成射流一抽一吐,会在射流部204产生涡对,所产生的负压会对内焰主火孔和外焰主火孔所出来的火焰进行控制,控制外焰向里偏转、内焰向外偏转。
大火时,通过合成射流可以控制外焰的偏转,使其向里偏转不同的角度,达到控制锅底加热面积范围的目的,使得锅底热量更集中,避免热量的浪费,且用小锅时,火焰热量集中在锅底部,避免锅把烫手的情形出现。此外,火焰向里偏转,增加高温烟气经过锅底的时间,提高燃气灶的能效,烟气接触到人的温度也会随之降低,减少炒菜带给人的不适感。
小火时,通过合成射流控制火焰向外偏转,根据炒菜所需锅底加热面积的大小调整火焰的偏转方向,从而使得小锅内食物受热更加均匀,增加用户烹饪的体验感。
合成射流无需额外引入气体,且涡对增加扰动,会促进其燃烧完全,减少火焰长度,对燃气灶的能效有提升作用。合成射流亦无需额外气源和相关装置,布置简单,功能强大,效果显著。
