Abstract

一种换气扇风轮,将截面呈弧形、轴向呈长方条 形的叶片轴向环形等距离排列于风轮面板上达到轴 向进气、径向排气。换气扇可安装在四壁与其它房间 相邻的房间或较大房间的中部部分的天花板上,通过 管道,将这部分的气体抽出而换气,同时降低了安装 的劳动强度。

Description

本实用新型涉及一种换气扇风轮。
传统的换气扇,其风轮叶片为两叶至六叶,与电机轴径向呈较小弧度均匀环形排布,气流进出风扇不改变方向,为轴流式。这种换气扇一般只能使用在隔离墙上,不能用在四壁与其它房间相邻的房间,对于较大房间的中间部分,换气效果也较差。同时在隔离墙上安装也增加了劳动强度。
本实用新型的目的就在于克服传统换气扇的换气效果差、安装劳动强度大的缺点,提供一种进风向与出风向呈垂直方向的换气扇风轮。
本实用新型是这样实现的。
采用二十至五十根风轮叶片轴向环形等距离地排列于风轮面板上,即叶片排列方向与电机轴的方向相同;同时叶片轴向呈长条形截面呈弧形,并从近电机端至远电机端逐渐偏离电机径向(离心式);风轮面板包盖住电机并作为叶片的支撑板,支撑在叶片的近中央位置,叶片的远电机端、电机的对侧通过一圆环连接在一起。
下面结合附图和实施例对本实用新型作进一步的说明。
图1为本实用新型的风轮的示意图,该方向为内轮面板紧贴电机的方向。
图2为本实用新型的风轮的轴向示意图。
图3为本实用新型的叶片的示意图。
图中,二十至五十根风轮叶片(2)轴向环形等距离排列于风轮(1)面板上,叶片排列方向与电机轴(4)的方向相同;风轮面板包盖住电机(5)作为叶片的支撑板,支撑在叶片的近中央位置,叶片轴向呈长条形,截面呈弧形,并从近电机端(中心)到远电机端逐渐偏离电机径向(离心式)。
叶片的远电机端、电机的对侧通过一圆环(3)连接在一起。
本实用新型的采用,改变以往的气流的轴向进出的特点,达到轴向进气,径向排出。这样,换气扇可安装在四壁与其它房间相邻的房间或较大房间的中间部分的天花板上,通过管道,将这部分的气体抽出而换气。同时在天花板上预留安装工位,也可降低劳动强度,方便施工。
