Abstract

The invention relates to a range hood with a vibration reduction function, comprising: a fan frame, including a fixing plate, the fixing plate is configured as a frame structure with an accommodation space; a fan system is arranged in the accommodation space of the fan frame, It is connected with the fixed plate; the fan cover is arranged on the outside of the fixed plate of the fan frame, and there is a gap between it and the fixed plate; it also includes a vibration damping device arranged in the gap between the fan cover and the fixed plate, including: the base , set on the outer cover of the fan; movable parts, constrained on the base in a way that can be moved closer to or farther away from the fixed plate and can be adjusted in position; elastic parts, set on the movable parts, act on the fixed plate, and can move Move to adjust the force applied to the fixed plate. It can compensate the modal error caused by the processing problem of the fan frame, so that the modal frequency of the fan frame can be effectively kept away from the frequency of the excitation source of the motor, avoiding the risk of resonance, reducing abnormal noise, and improving reliability and sound quality . It also relates to a vibration damping control method.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood with a vibration reduction function and a vibration reduction control method for the range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Most of the existing range hoods are made of sheet metal. In most c...
