Abstract

The invention discloses an air pressure control method and device for a range hood. The range hood comprises a fan. The air pressure control method comprises the steps that the frequency of the fan and the air speed of an outlet of the fan are obtained, and an air volume actual value, air pressure of the outlet of the fan and pressure of a public flue are determined according to the frequency of the fan and the air speed of the outlet of the fan; and if the air pressure of the outlet of the fan exceeds a set range of an air pressure set value, the target frequency of the fan under the pressure of the public flue is calculated according to the air pressure of the outlet of the fan, the air pressure set value and the air volume actual value, and the fan is adjusted. According to the air pressure control method and device for the range hood, the range hood is controlled through air speed feedback sensing to achieve constant effective air pressure.

Description

Technical field [0001] The present invention relates to flue gas treatment techniques, and more particularly to a wind pressure control method and apparatus for a hood. Background technique [0002] The hood is mounted in the upper or side of the hob, integrated with a fan. The operating process of existing hood is rotated to form a negative pressure area above the stove above a certain spatial range, and the indoor oil cigarette is inserted into the hood inside, the smoke gas passes Purification is separated as oil droplets and flue gas, and the oil droplets are collected from the oil cup, and the flue gas is discharged along the flue. [0003] The hood has a set of wind pressure and air volume. The wind pressure and air of the hood nominal in the market is currently tested under the laboratory conditions. However, during the actual use, the product is different due to the actual effective wind pressure in different use environments due to the actual use of tobacco pipe resistan...
