Description

燃烧器组件及燃气灶 技术领域
本发明涉及燃气灶技术领域，特别涉及一种燃烧器组件及燃气灶。
背景技术
现有技术中的燃烧器组件通常由炉头、设置于炉头上的分气盘、以及安装于分气盘上的火盖组件构成。由于炉头和分气盘均需要耐高温，一般对炉头和分气盘的配合面进行精细的磨平处理，以保持两者的配合面的平整度，进而有效防止燃气泄漏。然而在实际的加工过程中，炉头与分气盘的配合面存在加工误差并不能完全密封。而且在实际的工作过程中，炉头和分气盘受热膨胀，炉头与分气盘的配合面也会部分撑开，难以保证炉头和分气盘密封的可靠性，致使燃气灶存在燃气泄漏的问题。
发明内容
本发明的主要目的是提供一种燃烧器组件，旨在提高炉头与分气盘之间密封的可靠性，防止炉头内的燃气泄漏。
为实现上述目的，本发明提出的燃烧器组件，包括炉头，安装于所述炉头上的分气盘，以及位于所述炉头与分气盘之间的软金属密封圈。所述分气盘在底部具有第一配合面，所述炉头在顶部具有第二配合面；所述软金属密封圈具有第一表面及与第一表面相对的第二表面，所述第一表面与所述分气盘的第一配合面密封配合，所述第二表面与所述炉头的第二配合面密封配合。
优选地，所述炉头顶部的周缘设有环形凸条，所述炉头顶部向上延伸有位于所述环形凸条内的围壁；
所述分气盘的底部对应所述环形凸条设有第一凸缘，且分气盘的底部对应所述围壁凸设有第二凸缘；
所述软金属密封圈包括第一密封圈和第二密封圈，所述第一密封圈的第一表面抵接第一凸缘，第二表面抵接环形凸条的顶部；所述第二密封圈的第一表面抵接第二凸缘，第二表面抵接围壁的顶部。
优选地，所述第一密封圈固定于所述第一凸缘上，所述第二密封圈固定于第二凸缘上。
优选地，所述第一密封圈的第一表面粘接或通过螺钉螺接于所述第一凸缘上，第二表面粘接于所述环形凸条的顶部；所述第二密封圈的第一表面粘接或通过螺钉螺接于所述第二凸缘上，第二表面粘接于所述围壁的顶部。
优选地，所述第一密封圈的第二表面上设置有与所述环形凸条的顶部粘接的背胶 层，所述第二密封圈的第二表面上设置有与所述围壁的顶部粘接的背胶层。
优选地，所述软金属密封圈的材质为铝或铜。
优选地，所述软金属密封圈的厚度为0.1-0.5mm。
优选地，所述软金属密封圈自第一表面至第二表面的方向设置有第一材料层和第二材料层，所述第一材料层的材质与所述分气盘材质相同，所述第二材料层的材质与所述炉头材质相同，所述第一材料层与第二材料层一体成型。
优选地，所述分气盘和第一材料层的材质均为铝或铜，所述炉头和第二材料层的材质均为铁。
本发明还提出一种燃气灶，包括面板、底壳以及燃烧器组件，所述面板盖合于底壳上并与底壳围合成容纳燃烧器组件的容纳空间，所述燃烧器组件包括炉头，安装于所述炉头上的分气盘，以及位于所述炉头与分气盘之间的软金属密封圈，所述分气盘在底部具有第一配合面，所述炉头在顶部具有第二配合面；所述软金属密封圈具有第一表面及与第一表面相对的第二表面，所述第一表面与所述分气盘的第一配合面密封配合，所述第二表面与所述炉头的第二配合面密封配合。
在本发明技术方案中，炉头和分气盘之间增设软金属密封圈，该软金属密封圈的第一表面抵接分气盘的第一配合面，并且软金属密封圈的第二表面抵接炉头的第二配合面，从而达到较佳的密封效果。燃烧器组件工作时，分气盘和炉头均受热膨胀，由于软金属密封圈具有较佳的热伸缩性能，受热膨胀的分气盘的第一配合面压紧并贴合于软金属密封圈的第一表面，受热膨胀的炉头的第二配合面压紧并贴合于软金属密封圈的第二表面，从而利用软金属密封圈的伸缩性使炉头与分气盘更好地密封配合，有效防止燃气灶漏气，达到较佳的安全性能。

请参照图1，在本实施例中，该燃烧器组件包括炉头5，安装于所述炉头5上的分 气盘3以及固定于所述分气盘3上的火盖组件，还包括位于所述炉头5与分气盘3之间的软金属密封圈4。所述分气盘3在底部具有第一配合面，所述炉头5在顶部具有第二配合面。所述软金属密封圈4具有第一表面及与第一表面相对的第二表面，在炉头5和分气盘3受热膨胀时，所述第一表面与所述分气盘3的第一配合面密封配合，所述第二表面与所述炉头5的第二配合面密封配合。上述的火盖组件可以包括内环火盖1和外环火盖2，也可以只有一个火盖。于本实施例中，火盖组件包含内环火盖1和外环火盖2。上述的炉头5通过引射管53进气，而引射管53基于文丘里原理设计，能够增加燃气的进气速度。
在本发明技术方案中，炉头5和分气盘3之间增设软金属密封圈4，该软金属密封圈4的第一表面抵接分气盘3的第一配合面，并且软金属密封圈4的第二表面抵接炉头5的第二配合面，从而达到较佳的密封效果。燃烧器组件工作时，分气盘3和炉头5均受热膨胀，由于软金属密封圈4具有较佳的热伸缩性能，受热膨胀的分气盘3的第一配合面压紧并贴合于软金属密封圈4的第一表面，受热膨胀的炉头5的第二配合面压紧并贴合于软金属密封圈4的第二表面，从而利用软金属密封圈4的伸缩性使炉头5与分气盘3更好地密封配合，有效防止燃气泄漏，达到较佳的安全性能。
参照图1至图6，在一优选的实施例中，所述炉头5顶部的周缘设有环形凸条52，所述炉头5顶部向上延伸有位于所述环形凸条52内的围壁51。
所述分气盘3的底部对应所述环形凸条52设有第一凸缘32，且分气盘3的底部对应所述围壁51设有第二凸缘31。
所述软金属密封圈4包括第一密封圈4b和第二密封圈4a，所述第一密封圈4b的第一表面抵接第一凸缘32，第二表面抵接环形凸条52的顶部；所述第二密封圈4a的第一表面抵接第二凸缘31，第二表面抵接围壁51的顶部。
本发明的实施例中，第一密封圈4b位于第一凸缘32和环形凸条52之间，可以方便第一密封圈4b的固定。当然，第一凸缘32和凸条的配合方式不仅为一种实施方式，还可以是其他的配合方式，如凸条与凹槽之间的配合，或者两个凹槽之间的配合，均可以用第一密封圈4b来实现密封。第二密封圈4a的功能和第一密封圈4b的功能类似，第二密封圈4a的结构连接和第一密封圈4b的结构连接类似，此处不再赘述。
参照图1至图4，在一优选的实施例中，所述第一密封圈4b固定于所述第一凸缘32上，所述第二密封圈4a固定于第二凸缘31上。为了方便第一密封圈4b和第二密封圈4a的固定，第一密封圈4b可以直接安装于第一凸缘32上，亦或是第一密封圈4b可以直接安装于环形凸条52。上述的第一密封圈4b的面积与第一凸缘32的面积相适应，以实现第一凸缘32和环形凸条52完全贴合。第二密封圈4a的功能和第一密封圈4b的功能类似，第二密封圈4a的结构连接和第一密封圈4b的结构连接类似，此处不再赘述。
参照图5，在一优选的实施例中，所述第一密封圈4b的第一表面粘接或通过螺钉螺接于所述第一凸缘32，第二表面粘接于所述环形凸条52的顶部；所述第二密封圈4a的第一表面粘接或通过螺钉螺接于所述第二凸缘31，第二表面粘接于所述围壁51的顶 部。为了进一步提高第一密封圈4b及第二密封圈4a装配的稳定性，可以采用背胶的方式对第一密封圈4b及第二密封圈4a进行粘贴固定，也可以通过螺钉螺接固定。除此之外，还可以采用分气盘3与炉头5螺接固定的方式，夹紧第一密封圈4b和第二密封圈4a。
在一优选的实施例中，所述第一密封圈4b的第二表面上设置有与所述环形凸条52的顶部粘接的背胶层(未标出)，所述第二密封圈4a的第二表面上设置有与所述围壁51的顶部粘接的背胶层。本发明的实施例中背胶层，能够进一步提高第一密封圈4b与环形凸条52，以及第二密封圈4a与围壁51的密封性，以防止燃气泄漏；还能省去涂胶的工序，提高工作效率。
在一优选的实施例中，所述软金属密封圈4的材质为铝或铜。铝和铜具有较佳的热伸缩性和耐热性能，除此之外，还可以选用其他的金属或者合金材料，只需满足耐高温和具有较佳热伸缩性两个条件即可。
在一优选的实施例中，所述软金属密封圈4的厚度为0.1-0.5mm。优选地，软金属密封圈4的厚度为0.2-0.4mm。为了节省软金属密封圈4的材料可以将软金属密封圈4的厚度减小，而为了满足软金属密封圈4具有较佳的热伸缩性，可以适当的增加厚度。可以理解的是，其他的厚度均为可行方案，软金属密封圈4具体的厚度可根据设计的需求灵活设计。
参照图6和图7，在一优选的实施例中，所述软金属密封圈4自第一表面至第二表面的方向设置有第一材料层41和第二材料层42，第一材料层41的材质与所述分气盘3材质相同，第二材料层42的材质与所述炉头5材质相同，所述第一材料层41与第二材料层42一体成型。为了进一步提高密封性能，软金属密封圈4具有两层，在制作时可以沉积或涂镀两层不同的热伸缩金属，以使分气盘3与第一材料层41，以及炉头5与第二材料层42的材质相同，同样的材质耐温性能相同。本技术方案能够缓解不同部件之间因为材料不同而出现的较大挤压形变，因而能够有效防止燃气泄漏。
参照图6和图7，在一优选的实施例中，所述分气盘3和第一材料层41的材质均为铝或铜，所述炉头5和第二材料层42的材质均为铁。本实施例中，分气盘3的材质为铝或铜，而炉头5的材质为铁，为了减少受热时分气盘3与炉头5的挤压，软金属密封圈4的第一材料层41与分气盘3的材质相同，软金属密封圈4的第二材料层42与炉头5的材质相同。
参照图8，本发明还提出一种燃气灶，该燃气灶包括面板3`、底壳2`以及燃烧器组件1`，所述面板3`盖合于底壳2`上并与底壳2`围合成容纳燃烧器组件1`的容纳空间，该燃烧器组件1`的进气端与气管组件4`连通。该燃烧器组件的具体结构参照上述实施例，由于本燃气灶采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
该炉头5设置有三条引射管53，炉头5内部具有内环通道、中环通道及外环通道分别对应连接有三个引射管，采用三通道独立燃烧引射，能够提高燃气灶的通气量。三个 引射管均采用基于文丘里原理的结构，能够加速燃气导出的速率。内环火盖1的与第一传火通道连通的第一火孔、与第二传火通道连通的第二火孔及外环火盖2的主火孔，采用三级助燃技术，能够使燃气燃烧得更充分，提高燃气效率。另外，整个燃气灶在喷嘴、引射管口及分气盘3上分别采用引射助燃，采用三级空气引射助燃技术，能够提高燃气的燃烧效率，节省燃气成本，进而提高整个产品的品质。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
