Abstract

The invention discloses an adjusting method and device for a range hood. The range hood comprises a fan. The adjusting method comprises the steps that operation parameters of the fan are collected, and an air volume actual value of the fan, an air pressure actual value of the fan and pressure of a public flue are obtained through calculation; a target air pressure interval where the air pressure actual value of the fan is located and an air volume set value corresponding to the target air pressure interval are determined, and if the air volume actual value of the fan exceeds a set range of the air volume set value, the air volume set value is determined as a target air volume set value; and according to the air volume actual value of the fan and the target air volume set value, target adjusting parameters of the fan are obtained through calculation, and the fan is adjusted. According to the adjusting method and device for the range hood, parameters of the range hood are controlled and adjusted through feedback sensing of the operation parameter of the fan to achieve stage air volume control, and for a range hood under a poor working condition, enough rotating speed can be output, so that it is guaranteed that the effective air volume is not reduced; and for a range hood under a good working condition, the rotating speed can be reduced, so that noise is reduced while the fume suction effect is guaranteed, the user experience is improved, and staged constant air volume is realized.

Description

technical field [0001] The invention relates to flue gas treatment technology, in particular to a method and device for adjusting a smoke machine. Background technique [0002] The range hood is installed on the top or side of the stove and is integrated with a fan. Its working principle is that the fan 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. The fume gas is purified and separated into oil droplets and smoke, and the oil droplets are collected into the oil cup. The flue gas is discharged along the flue. [0003] Range hoods have multiple gears, and each gear corresponds to a set air volume. The air volumes of range hoods currently on the market in the nominal gears are all ideal values ​​set by testing under laboratory conditions. In the actual use process, due to the resistance of the flue pipe and the pressure of the public flue, the actual effective air volume of th...
