Abstract

本实用新型是家用炉灶引风机。可以安到烟囱壁上,室内室外都可安装。引风机结构简单,制造工艺简单,节省原材料,造价可比现有引风机下降20%。零件不易腐蚀损坏,维护方便。

Description

本实用新型是家用炉灶引风机。
现有炉灶用的引风机,是安装在烟囱的顶口上,由于是露天安放,需有防护罩及比较重的机座。冬天有时机座掛冰,容易损坏引风机,对引风机的维护也比较困难,很容易失盗。
本实用新型的目的是提供一种能安装在烟囱壁上的引风机。它不用防护罩,结构简单造价低,方便对引风机的维护。
发明是这样实现的:引风机机体借助于烟道壁,装在烟道内,其机座固定在烟道壁上,机座上装有电机、电机轴伸向固定在烟道上挡板的出烟孔中,电机轴上的叶轮安装在出烟孔位置。当烟气被抽到挡板的部位时,烟气便顺引风机轴的方向,通过挡板的出烟孔,排到叶轮的后部,拐回烟道,通向大气。
本实用新型结构简单,制造工艺简单,节省原材料,造价可比现有引风机降低20%。安装在室内外均可,维护方便。零件不易腐蚀损坏寿命长。
以下结合附图对本实用新型作进一步详细说明。
附图是本实用新型简易炉灶引风机,安装在烟囱壁上的位置图。
〔1〕电动机、〔2〕顶丝、〔3〕机座、〔4〕叶轮、〔5〕挡板、〔6〕烟囱壁〔墙壁〕。
附图上箭头指的方向是烟气经过引风机的过程。叶轮〔4〕的叶片的间隙,在停电时足够烟的流通所需的面积。电动机〔1〕的轴、叶轮〔4〕、机座〔3〕机械连接成一体,安装时叶轮安在挡板〔5〕的出烟孔位置,由叶轮〔4〕排出的烟气通过墙壁上开出的烟道拐进烟囱。
挡板〔5〕可以用水泥、陶土、铸铁和钢板等材料制造。
