Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a filter replacement structure for a kitchen range hood. Background Art

[0002] The filter for kitchen range hood refers to a filtering device installed inside the range hood, which is used to filter and capture grease particles and pollutants in the fumes. It is usually made of metal mesh or fiber material, has a large surface area and fine pores, and can effectively prevent solid particles in the fumes from passing through. When the fumes generated during cooking are extracted by the range hood, they will be filtered through the filter, leaving the grease particles and pollutants on the filter, allowing the purified air to be discharged to protect the internal components: the filter can prevent grease particles from entering the interior of the range hood, avoid clogging the air duct and affecting the normal operation of the range hood, and can also extend the service life of other components (such as motors, fans, etc.).
