Abstract

一种排风管连接结构,在油烟机上方固定出风 口,出风口上具有较深的排油槽,将排风管嵌插入槽 中得以紧固。该连接结构使油烟机处于非工作状态 时,沉积吸附在排风管内壁上的油污顺着内管壁下流 至排油槽,当油槽积油外溢时,会顺着出风口内壁下 流进入风机流向油杯被收集。本结构不仅省去了抱 箍等锁紧构件,降低了产品成本,外形又美观,且杜绝 了油污溢向机外造成整机顶部漏油之弊端,提高了产 品质量。

Description

本实用新型涉及油烟机排风管的连接结构。
油烟机中的排风管是风机抽吸的油烟、油气及燃料燃烧未尽的废气排放到室外的必经之道,因此不仅要求排放通畅,而且要解决沉积在排风管内壁上的油污的收集。目前油烟机的排风管是套装在出风口管外径上,为了使其牢固,再加装抱箍紧固,这种套装结构的缺陷不仅增加抱箍等锁紧构件,影响外形美观,而且当油烟机停止工作时,沉积吸附在排风管内壁上的油污会顺着管壁下流,通过排风管与出风口接触面的间隙而流积在整机顶部,导致整机顶部漏油。
本实用新型目的在于克服现有技术的缺陷而提供一种既美观、省另件又解决漏油问题的排风管连接结构。
本实用新型的实施方案即在油烟机的上方固定出风口、通向室外的排风管装在出风口上,出风口上设计排油槽,排风管嵌插在排油槽中,排油槽是外边高、内边低的环形槽。
此排风管连接结构不仅省去了抱箍等锁紧构件,降低了产品成本,外形美观,且避免了油污溢向机外的漏油现象,提高了产品质量。
附图1公开了本实用新型的结构示意图。
根据附图1提供的结构方案,本实用新型排风管连接结构即在油烟机(3)的上方固定出风口(2),将出风口(2)上口设计成具有较深的排油槽,该槽是外边高、内边低的环形槽,槽的宽度与排风管(1)的壁厚相匹配,将排风管(1)直接嵌插入排油槽中,紧密配合,利用其材料的弹性而被紧固。当油槽积油外溢时,就顺着出风口(2)内壁下流进入风机而流向油杯被收集。

Claims (2)

1、一种油烟机的排风管连接结构,在油烟机(3)的上方固定出风口(2),通向室外的排风管(1)装在出风口(2)上,其特征在于出风口(2)上具有排油槽,排风管(1)嵌插在槽中。
2、如权利要求1所述的排风管连接结构,其特征在于所述排油槽为外边高、内边低的环形槽。
