Description

Technical Field

[0002] The range hood, also known as the range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste burned in the stove and the oil smoke generated during the cooking process that is harmful to the human body and discharge them outdoors, reducing pollution, purifying the air, and has the safety protection function of anti-toxicity and explosion-proof. The range hood needs to be cleaned regularly. Simple cleaning cannot handle the oil stains. Professional cleaning agents must be used to clean the range hood. The range hood is installed on the top of the stove. The power of the range hood is turned on and the motor is driven to make the wind wheel rotate at high speed, so that a negative pressure area is formed within a certain space above the stove, and the indoor oil fume gas is sucked into the range hood. The oil fume gas is filtered through the oil net for the first oil fume separation, and then enters the inside of the range hood air duct. The oil fume gas is separated for the second time through the rotation of the impeller. The oil fume in the wind cabinet is affected by centrifugal force, and the oil mist condenses into oil droplets, which are collected in the oil cup through the oil path, and the purified smoke is finally discharged along a fixed passage.

[0003] After the range hood has been used for a long time, a lot of oil will condense on the outer filter, which is inconvenient to clean and takes a lot of time. Sometimes, if you forget to clean it, the oil on the surface will become thicker, increasing the difficulty of cleaning. Summary of the invention
