[0002] Ventilation fans are widely used in daily life. Nowadays, in order to ventilate the confined space, ventilation fans are installed in bathrooms or kitchens where ventilation is required. Existing ventilation fans have the following disadvantages: they can only be turned on or off by a single control, and the ventilation volume cannot be adjusted. Do variable air volume adjustment or cannot adjust the air volume through multiple gears, cannot choose the ultra-quiet mode for ventilation at night, and cannot adjust the air volume of the ventilation fan according to actual needs. While increasing the indoor environmental noise, it also wastes a lot of power energy consumption

Abstract
The invention discloses a ventilating fan with variable air volume. The ventilating fan comprises a multi-gear adjustable-speed motor, a back cover plate, an air guide volute, a centrifugal wind wheel, an electric appliance protection box, an air outlet, a check valve elastic piece, multi-wire-column-position wiring terminals, a small-size capacitor, a wire pressing device and an air outlet decorative cover plate, wherein the centrifugal wind wheel and the motor are concentrically connected with a shaft of the motor as the center and then are arranged in the air guide volute; and by supplyingpower to wiring terminals on the multi-wire-column-position wiring terminals in a grading mode, the motor operates according to the preset gear rotating speed to drive the centrifugal wind wheel, thecheck valve elastic piece installed on the air outlet is opened through the passed air flow, and the ventilating fan with the variable air volume operates according to one air volume state.
Description
technical field [0001] The invention relates to a ventilating fan, in particular to a ventilating fan with variable air volume, and the ventilating fan which can be adjusted with a plurality of stalls to realize the variable air volume. Background technique [0002] Ventilation fans are widely used in daily life. Nowadays, in order to ventilate the confined space, ventilation fans are installed in bathrooms or kitchens where ventilation is required. Existing ventilation fans have the following disadvantages: they can only be turned on or off by a single control, and the ventilation volume cannot be adjusted. Do variable air volume adjustment or cannot adjust the air volume through multiple gears, cannot choose the ultra-quiet mode for ventilation at night, and cannot adjust the air volume of the ventilation fan according to actual needs. While increasing the indoor environmental noise, it also wastes a lot of power energy consumption. [0003] Such as figure 1 As shown, ...
