    Abstract: Equipment for preventing a blower for an HVAC(Heating Ventilation and Air Conditioning) from flowing backward is provided to improve an amount of wind and efficiency by reducing back flow into a gap between the bell mouse and the ventilation wheel. In equipment for preventing a blower for an HVAC from flowing backward, a plurality of blades(130) is vertically formed on a ventilation wheel(110) along a circumference direction. A motor(140) rotatably drives the ventilation wheel. A ventilation case has an intake port with a bell mouse(150), wherein the ventilation wheel and the motor are received inside of the ventilation case. A plurality of bands(160a,160b,160c) is formed around a top portion of the ventilation wheel in a direction vertical to the blades. At least three periods increase an amount of wind and efficiency of the blower. And, the equipment for preventing the blower for an HVAC from flowing backward reduces noises by reducing an abnormal pressure disturbance due to the backward flow.

    Abstract translation: 提供用于防止HVAC（加热通风和空调）的鼓风机向后流动的设备，以通过减少回到钟形鼠标和通风轮之间的间隙的流量来改善风量和效率。 在用于防止HVAC的鼓风机向后流动的设备中，沿着圆周方向在多个叶片（130）垂直地形成在通风轮（110）上。 电动机（140）可旋转地驱动通风轮。 一个通风柜具有一个带有喇叭（150）的进气口，其中通风轮和马达被容纳在通风柜的内部。 在与叶片垂直的方向上围绕通气轮的顶部形成多个带（160a，160b，160c）。 至少有三个时期可以增加鼓风机的风量和效率。 并且，用于防止HVAC的鼓风机向后流动的设备通过减少由于向后流动引起的异常压力扰动而降低噪声。
