Description

一种燃气喷嘴组件及应用其的燃气加热装置 技术领域
本发明属于家用电器技术领域，具体地说，涉及一种燃气喷嘴组件及应用其的燃气加热装置。
背景技术
燃气加热装置是一种使燃料和空气以一定方式喷出混合燃烧的装置统称，具有燃烧效率高、加热速度快的优点，从而被广泛应用于家用电器技术领域，特别是具有燃气加热装置的干衣机和燃气热水器受到消费者青睐。燃气加热装置包括燃烧室、燃烧器、燃气喷嘴、进气管路等，其中燃烧器具有进口端和出口端，燃气喷嘴的喷气孔置于燃烧器的进口端，燃烧器设置于燃烧室内，燃气由喷气孔流入燃烧器内，进而被点燃用于加热燃烧室内的空气。
燃气喷嘴的进气端与进气管路以螺接或焊接的方式固定，而燃气喷嘴的喷气孔与燃烧器的进口端相对设置，一般通过将燃气喷嘴和燃烧器固定后，再将燃烧器置于燃烧室内以实现精准定位进气位置，但是更换燃气喷嘴时需要将燃烧器从燃烧室中移出，再将燃烧器和喷嘴拆下，更换过程比较繁琐，不利于燃气喷嘴的更换和日常维护，而将燃烧器固定于燃烧室后，再固定燃气喷嘴的进气位置，往往无法保证燃气喷嘴的喷气孔与燃烧器的进口端精准对位，导致燃气加热装置的燃烧效率低。
有鉴于此特提出本发明。
