The invention discloses a range hood system and an air volume feedback control method and device thereof. The range hood system comprises a range hood and a fan, and the fan is connected between the range hood and a public flue in series through a smoke exhaust pipe. The air volume feedback control method comprises the following steps that in the range hood control stage, a target constant air volume value is determined, according to the first range hood rotating speed to the Nth range hood rotating speed of the target constant air volume value, the rotating speed of the range hood is adjusted step by step so that the difference value between the range hood system air volume at the ith range hood rotating speed and the target constant air volume value can be within the preset air volume difference value range, and if the rotation speed of the ith range hood is greater than the preset maximum rotation speed in the adjusting process, a double-unit linkage stage is switched; and in the double-unit linkage stage, the fan is controlled to be started and adjusted, the rotating speed of the range hood is controlled to be smaller than or equal to the preset maximum rotating speed, and the rotating speed of the fan is adjusted step by step till the difference value of the range hood system air volume and the target constant air volume value is within the preset air volume difference value range. According to the range hood system and the air volume feedback control method, the working mode of the range hood system is controlled through air volume and rotating speed feedback, and constant effective air volume output and low noise are achieved.
Description
technical field [0001] The embodiments of the present invention relate to oil fume control technology, in particular to a hood system and an air volume feedback control method and device thereof. Background technique [0002] The range hood is installed on the top or side of the stove. The operation process of the existing range hood is that the hood rotates at high speed to form a negative pressure area in a certain space above the stove, and the indoor fume gas is sucked into the range hood, and the fume gas is purified and separated into Oil droplets and smoke, the oil droplets are collected into the oil cup, and the smoke is discharged along the flue. [0003] Range hoods have set gears. In actual use, due to loads such as public flue resistance, the actual air volume of the product is different under different usage environments, resulting in poor smoke exhaust effect and high noise, which cannot meet the needs of users. And other issues. Contents of the invention ...
