Abstract

The embodiment of the invention discloses a range hood system and a noise feedback control method and device thereof. The range hood system comprises a range hood assembly and a fan assembly; the noise feedback control method comprises the steps that in a first working stage, the range hood assembly is controlled to be started, the fan assembly is closed, the range hood assembly is driven to run to the i range hood rotating speed of a target constant air volume value so as to be matched with resistance of a public flue, and the situation that the noise of a current range hood system is larger than a specific noise value is judged in the matching process, the second working stage is switched; and in the second working stage, the range hood assembly is driven to keep running at the first-stage range hood rotating speed before the range hood rotating speed during switching, and the fan assembly is driven to run to the j fan rotating speed of the target constant air volume value till the j fan rotating speed is matched with the resistance of the public flue. According to the embodiment, the noise of the range hood system is controlled not to exceed a specific noise value through noise feedback, meanwhile, constant effective air volume can be outputted without arranging an air volume sensor, and the smoke suction effect is ensured.

Description

technical field [0001] Embodiments of the present invention relate to a range hood control technology, in particular to a range range system and a noise 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 ...
