Wind pressure type louver and ventilating fan using same
The invention discloses a wind pressure type louver and a ventilator using the same. The wind pressure type louver comprises an air port and a movable louver covering the air port. A plurality of sets of hinges are located on a plurality of horizontal lines, distributed from top to bottom, of the air port, and the corresponding number of integrated sheet-shaped louver blades are opened or closed around the hinge located on one of the horizontal lines. And when the movable shutter is in a closed state, the thickness of the part of the sheet above the hinge axis of each shutter blade is greater than that of the part of the sheet below the hinge axis of each shutter blade. The wind pressure type blind window can obtain a large opening angle, and therefore wind resistance is reduced, and noise is low.
一种风压式百叶窗和使用该百叶窗的换气扇。风压式百叶窗包括风口和遮隔该风口的活动百叶窗：若干组铰链位于该风口自上而下分布的多条水平线上，相应数量一体薄片状的窗叶各绕位于所述水平线之一的铰链张开或闭合；在活动百叶窗处于关闭状态时，各窗叶位于其铰链轴线之上部分薄片的厚度大于位于其铰链轴线之下部分薄片的厚度。该风压式百叶窗可获得较大的张开角度，并因而减少风阻和噪声较低。
