Abstract

The invention relates to an oil fume filtering device. The device comprises a filtering assembly and a first driving mechanism, wherein the filtering assembly comprises a cylindrical first filtering piece and a cylindrical second filtering piece, the second filtering piece is sleeved with the first filtering piece, and the first filtering piece is provided with distribution areas with different air inlet areas; and the first driving mechanism is respectively in driving connection with the first filtering piece and the second filtering piece. The invention further relates to a range hood which comprises an exhaust fume collecting hood, a fan, a connecting hood connected between an outlet of the exhaust fume collecting hood and an inlet of the fan, and a filtering device arranged in the connecting hood. The invention further relates to an oil fume filtering method of the range hood. The driving rotating speed of the second filtering piece is adjusted according to the oil fume concentration; and the first filtering piece is controlled and driven according to the noise data so as to adjust the air inlet area of the distribution area of the first filtering piece facing the oil fume inlet direction. The oil fume filtering device can realize dynamic separation of oil fume, and solves the noise problem on the basis of effectively ensuring the oil fume filtering effect.

Description

technical field [0001] The invention relates to an oil fume filtering device, and also relates to a range hood using the oil fume filtering device. Background technique [0002] The range hood is essential as a necessary kitchen appliance in the family. It can discharge some oily fumes and harmful gases generated during the cooking process. It is an essential appliance for indoor cleaning of the kitchen. However, the oily fumes generated during the cooking process will pollute the inside of the range hood, and the cleaning of the inside of the range hood has always been a big problem. A filter is installed at the air inlet to filter oil fume. [0003] In order to improve the effect of oil fume absorption, a multi-layer filter structure is usually used, such as the Chinese invention patent application "A Oil Fume Purification System" with the publication number CN112212379A (application number 202011204976.2), in which the oil fume separation net disclosed includes the outer...
