Range hood system and air pressure feedback control method and device thereof

Abstract

The embodiment of the invention discloses a range hood system and an air pressure feedback control method and device thereof. The range hood system comprises a range hood and a fan; the air pressure feedback control method comprises the steps that a target constant air volume value is obtained, and working parameters of a range hood are adjusted to be target working parameters, corresponding to the target constant air volume value, of the range hood; the air pressure of the range hood system is detected; and if the air pressure of the range hood system is larger than the preset air pressure value, the fan is started and adjusted till the air pressure of the range hood system is smaller than or equal to the preset air pressure value. According to the embodiment of the range hood system, the working parameters of the range hood are adjusted into the target working parameters corresponding to the target constant air volume value, so that the constant effective air volume is output; and if the air pressure of the range hood system is larger than the preset air pressure value, the fan is started and adjusted till the air pressure of the range hood system is smaller than or equal to the preset air pressure value, and the effective air pressure constantly lower than the preset air pressure value is output.

Description

Technical field[0001]Embodiments of the present invention relate to cigarette control techniques, and more particularly to a hood system and a wind pressure feedback control method and apparatus.Background technique[0002]The hood is mounted on the upper or side of the hob, the operating process of the existing hood is to form a negative pressure area above the hookage hook, and the indoor oil cigarette is inhaled into the exhaust hood, and the cigarette gas is purified into the hood. Oil droplets and flue gas, oil droplets are collected from the oil cup, and the flue gas is discharged along the flue.[0003]The hood has a set gear position. During the actual use process, due to the load of public flue resistance, the product has different wind pressure in different environments, so that the exhaustive effect is poor, noise, noise, can not meet the user Use problems such as use.Inventive content[0004]Embodiments of the present invention provide a hood system and a wind pressure feedbac...
