Abstract

The invention discloses a wind pressure control method and device for a hood. The hood includes a blower. The wind pressure control method includes: acquiring the frequency of the blower and the total outlet pressure of the blower, and obtaining the blower frequency according to the blower frequency and the total pressure of the blower outlet. Common flue pressure; if the total pressure at the outlet of the fan exceeds the setting range of the wind pressure setting value, determine the target frequency of the fan and adjust the fan according to the public flue pressure and the setting value of the wind pressure. In the present invention, the wind pressure feedback sensor is used to control the hood to achieve constant effective wind pressure. Specifically, the constant wind pressure control logic is used to achieve constant wind pressure. On the basis of satisfying the use of users on each floor, reduce the air volume and noise of users on the upper floors, while ensuring the smoking effect of users on the lower floors.

Description

technical field [0001] The invention relates to flue gas treatment technology, in particular to a wind pressure control method and device for a hood. Background technique [0002] The range hood is installed on the top or side of the stove, and is integrated with a fan. The operation process of the existing range hood is that the fan rotates at a high speed to form a negative pressure area in a certain space above the stove, and the indoor range hood is sucked into the range hood. The purification is separated into oil droplets and flue gas, the oil droplets are collected into the oil cup, and the flue gas is discharged along the flue. [0003] The range hood has multiple gears, and each gear corresponds to a set air volume. The air volume under the nominal gear of the current range hoods on the market is an ideal value tested and set under laboratory conditions. In the actual use process, due to the existence of the resistance of the smoke pipe and the pressure of the publ...
