Patent No. EP3710755 (titled "Range Hood Device For A Cooktop And Kitchen Furniture With Range Hood Device") was filed by BSH Hausgerte on Nov 9, 2018. The application was issued on Apr 9, 2025.
A vapour extraction apparatus for a hob comprises at least one suction opening on the upper side, a fan offset downwards from said opening, and a connecting channel between them. Downstream of the fan in the flow direction is a distributor space featuring at least one air outlet opening. This distributor space is delimited, at least partially, by sound attenuation material (e.g., foam plates or mats) to reduce centrifugal fan noise. At least one odour filter, such as an activated carbon filter, is positioned upstream of the fan. The apparatus may be integrated into kitchen furniture, utilizing a double-flow fan and a distributor space that may extend below the furniture base to the room floor.
