Description

technical field

[0001] The invention relates to a range hood, in particular to a low-noise surround top-side range hood. Background technique

[0002] The range hood is a kitchen appliance that purifies the kitchen environment. It is installed on the upper part of the range hood. After the range hood is powered on, it drives the motor to make the wind wheel rotate at a high speed, forming a negative pressure area in a certain space above the range hood, sucking the indoor fume gas into the range hood, and the fume gas passes through it. The oil screen is filtered for the first oil fume separation, and then enters the inside of the hood air duct, and the oil fume gas is separated for the second time through the rotation of the impeller. The oil fume in the air cabinet is subjected to centrifugal force, and the oil mist condenses into oil droplets , collected into the oil cup through the oil circuit, and the purified flue gas is finally discharged outside along a fixed path, ...
