Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a purification net for range hoods. Background Art

[0002] A range hood is an electrical device used to remove large amounts of oil smoke and harmful gases generated during the cooking process. It is usually installed above the kitchen wall and is driven by an electric motor to discharge the oil smoke to the outdoors. The purification net is a filtering device installed inside the range hood to adsorb and filter harmful substances in the oil smoke. The filtered oil smoke will then liquefy into waste oil on the surface of the purification net and flow downward along the purification net.

[0003] Existing purification nets generally do not collect waste oil, causing the waste oil to flow into the range hood. When cleaning the purification net, the range hood needs to be cleaned additionally. At the same time, if the waste oil is not discharged for a long time, it is easy to produce grease stains, which need to be removed during cleaning, which is time-consuming and laborious.
