Abstract

风动合页门属轴流风机加装的门结构装置。风动合页门结构有两个半页门组成，两半页门门轴紧靠，且与重力线成α角倾斜，出风时依靠风力，克服半页门重力倾斜分力，将门打开，反之关闭。本实用新型的优点是风阻小，完全打开时几乎无风阻，关闭时可防止灰尘杂物侵入。

Description

风动合页门
一、技术领域  本实用新型属轴流风机加装的门结构装置
二、背影技术  现轴流风机(如排风扇)出风口没有闭合门，有的装置百叶窗，风阻大且不能完全打开，若使用于抽排油烟，造成油脂垢在其上大量粘附。
三、发明内容  本实用新型是一种风动合页门装置，其技术方案是出风口有两个半页门，两半页门门轴紧靠，且与重力线成α角倾斜，α角为3-30°，出风时依靠风力，克服半页门的重力倾斜分力将门打开，反之关闭。本实用新型的优点是风阻小，完全打开时几乎无风阻，关闭时可防止灰尘杂物侵入。
四、附图  1、轴流风机室  2、半页门  3、门轴  4、与重力线倾角α
五、具体实施方式  本实用新型可按实施例图加以实现，在轴流风机室1，出风口装置两半页门2，两半页门门轴3紧靠，并与重力线成α角倾斜。

Claims (1)

1.风动合页门，由两门轴紧靠的半页门组合，其特征是两个半页门门轴与重力线成α角倾斜，α角大小为3°-30°。
