  • Cooker hood and filtering device thereof
    Patent number: 11313565
    Abstract: A filtering device of a cooker hood is configured in a V shape with an upward opening as a whole, and includes a V-shaped inner surface and a V-shaped outer surface. A tube portion is embedded between the inner surface and the outer surface, both ends of the tube portion being closed. The tube portion has a V shape with an upward opening. The tube portion includes an air inlet and an air outlet disposed in an interleaved manner, with the air inlet being located on the outer surface, and the air outlet being located on the inner surface. In this way, a rotating airflow is suitable to be formed in the tube portion of the filtering device, thereby improving a grease separation effect.
