Description

新型燃烧器的火排片 技术领域
本实用新型属于机械技术领域，涉及一种燃烧器，特别是一种新型燃烧器的火排片。
背景技术
目前，民用燃烧器已广泛应用于各个家庭中，例如燃气灶、壁挂炉等家庭用品，现有的壁挂炉是一种以天然气为能源的热水器，具有防冻保护、防干烧保护、意外熄火保护、温度过高保护、水泵防卡死保护等多种安全保护措施。壁挂炉具有强大的家庭中央供暖功能，所以被广泛应用，而众所周知，壁挂炉中的燃烧器是壁挂炉性能和效率的关键部件，所以火排组件作为燃烧器的主要组成部件，其性能就显得尤为重要。在实际的工作中，由于火排组件设计的缺陷，存在着燃烧器燃烧不充分的问题，导致燃烧器排放的烟气含有的氮氧化物的含量比较高。
现有技术中，可通过在设计冷却装置来降低火排组件工作时的燃烧温度，从而使燃气燃烧更加充分，来降低氮氧化物的排放，但在燃烧器中增加冷却装置，会增大燃烧器的体积，占用空间变大，导致运输、安装不方便等问题。
如中国专利文献公开的一种低氮燃烧器火排组件(申请号：201721560894.5)，包括火排及设置在火排上端的火孔片，火排内部的两端设置有两个相连通的文丘里管，所述文丘里管为下端窄并逐渐向上扩大的进气管道，两个所述文丘里管的上端均设置有导流压槽，两个所述文丘里管之间设置有若干个冷却管孔，所述火孔片上端均匀开设有若干个火孔，所述文丘里管与若干个所述 火孔相连通。但该低氮燃烧器火排组件的进气管道呈垂直设置，应该容易产生回火且该火排组件的火排孔只能朝上设置，因此其适用范围不广。
发明内容
本实用新型的目的是针对现有的技术存在上述问题，提出了一种不易产生回火且适用范围较广的新型燃烧器的火排片。
本实用新型的目的可通过下列技术方案来实现：新型燃烧器的火排片，包括壳体，所述的壳体的两侧均设有进气通道，两个所述的进气通道对称设置，所述的壳体的上端具有燃烧腔，所述的进气通道的上端与所述的燃烧腔相连通，所述的燃烧腔的上端设有燃烧板，其特征在于，所述的进气通道包括进气部以及引流部，所述的引流部的上下两端分别与燃烧腔以及进气部的上端相连通，所述的进气部的下端为进气口，所述的进气部由下往上往壳体的外侧倾斜设置，所述的引流部由下往上往壳体的中部倾斜设置。
当燃气沿着进气部进入进气通道，并带动进气部的进气口处的空气往进气通道流动，燃气和空气混合并流经引流部至燃烧腔，在燃烧腔的燃烧板处燃烧，由于进气部由下往上往壳体的外侧倾斜设置，引流部由下往上往壳体的中部倾斜设置，能够有效降低燃烧产生的回火，提高了燃烧效率，同时相对于普通的火排片的竖直设置的进气通道，本火排片具有结构紧凑、节省材料从而降低了成本。同时本新型燃烧器的火排片适用于倒置安装，即燃烧腔位于下侧，进气口位于上侧，具有使用灵活且适用范围较广的优点。
在上述的新型燃烧器的火排片中，所述的进气部的下端为进气口且所述的进气口为开口朝下的喇叭口。进气口呈喇叭口，具 有进气效果较好的优点。
在上述的新型燃烧器的火排片中，引流部的下端宽度大于其上端宽度。采用上述设置，能够有效的避免回火，提高了燃烧效率。
在上述的新型燃烧器的火排片中，所述的进气部呈直孔状且所述的进气部的轴线与水平线形成的夹角a为52°-65°。作为优选的，进气部与水平线形成的夹角a为60°。
在上述的新型燃烧器的火排片中，所述的引流部的外侧壁上均设有定位凸台且所述的定位凸台均对称设置。本燃烧器相邻的火排片之间的定位凸台相抵靠，对火排片具有较好的定位效果，从而降低了火排的壳体的加工精度，降低了制造成本。
在上述的新型燃烧器的火排片中，所述的壳体包括中部具有凹槽的板体一以及板体二，所述的板体一的凹槽与板体二的凹槽形成上述的燃烧腔以及进气通道。板体一与板体二的凹槽形成上述的燃烧腔以及进气通道，具有结构简单且制造较为方便的优点。
在上述的新型燃烧器的火排片中，所述的板体一贴靠在所述的板体二上且所述的板体一的两侧具有翻边且所述的翻边贴靠在所述的板体二的外侧壁上。板体一的翻边贴靠在板体二上实现板体一与板体二相固连，具有连接牢固且制造较为方便，同时避免燃烧腔内的燃气泄漏。
在上述的新型燃烧器的火排片中，所述的壳体的中部设有若干供冷却管穿过的连通孔，且所述的连通孔位于两个所述的进气通道之间。通过设置上述的连通孔，便于冷却管的插入，具有安装较为方便的优点。
在上述的新型燃烧器的火排片中，所述的板体一以及所述的板体二均采用铝合金制成。板体一以及板体二均采用铝合金制成，具有质量较轻且使用寿命较长的优点。作为另一种方式，板体一 以及所述的板体二均采用不锈钢材料制成。
与现有技术相比，本新型燃烧器的火排片具有以下优点：
1、由于进气部由下往上往壳体的外侧倾斜设置，引流部由下往上往壳体的中部倾斜设置，能够有效降低燃烧产生的回火，提高了燃烧效率，同时相对于普通的火排片的竖直设置的进气通道，本火排片具有结构紧凑、节省材料从而降低了成本；
2、由于进气部由下往上往壳体的外侧倾斜设置，引流部由下往上往壳体的中部倾斜设置，本新型燃烧器的火排片适用于倒置安装，即燃烧腔位于下侧，进气口位于上侧，具有使用灵活且适用范围较广的优点；
3、引流部的下端宽度大于其上端宽度，能够有效的避免回火，提高了燃烧效率；
4、本燃烧器相邻的火排片之间的定位凸台相抵靠，对火排片具有较好的定位效果，从而降低了火排的壳体的加工精度，降低了制造成本。

进气部2a由下往上往壳体1的外侧倾斜设置，进气部2a呈直孔状且进气部2a的轴线与水平线形成的夹角a为52°-65°。作为优选的，进气部2a与水平线形成的夹角a为60°。
引流部2b由下往上往壳体1的中部倾斜设置，引流部2b的下端宽度大于其上端宽度，能够有效的避免回火，提高了燃烧效率。引流部2b的外侧壁上均设有定位凸台5且定位凸台5均对称设置。
壳体1包括中部具有凹槽的板体一以及板体二，板体一以及板体二均采用铝合金制成。板体一的凹槽与板体二的凹槽形成上述的燃烧腔3以及进气通道2，具有结构简单且制造较为方便的优点。板体一贴靠在板体二上且板体一的两侧具有翻边6且翻边6贴靠在板体二的外侧壁上，实现板体一与板体二相固连，具有连接牢固且制造较为方便，同时避免燃烧腔3内的燃气泄漏。

当燃气沿着进气部2a进入进气通道2，并带动进气部2a的进气口2c处的空气往进气通道2流动，燃气和空气混合并流经引流部2b至燃烧腔3，在燃烧腔3的燃烧板4处燃烧，由于进气部2a由下往上往壳体1的外侧倾斜设置，引流部2b由下往上往壳体1的中部倾斜设置，能够有效降低燃烧产生的回火，提高了燃 烧效率，同时相对于普通的火排片的竖直设置的进气通道，本火排片具有结构紧凑、节省材料从而降低了成本。同时本新型燃烧器的火排片适用于倒置安装，即燃烧腔3位于下侧，进气口2c位于上侧，具有使用灵活且适用范围较广的优点。进气口2c呈喇叭口，具有进气效果较好的优点。燃烧器相邻的火排片之间的定位凸台5相抵靠，对火排片具有较好的定位效果，从而降低了火排的壳体1的加工精度，降低了制造成本。
板体一以及板体二均采用铝合金制成，具有质量较轻且使用寿命较长的优点。作为另一种方式，板体一以及板体二均采用不锈钢材料制成。
