AI Technical Summary
Technical Problem
Conventional extractor hoods require elaborate and difficult-to-clean separation elements to achieve high separation efficiency of cooking fumes, particularly grease and oil, leading to inefficiencies and environmental pollution.
Method used
Incorporation of a co-current cyclone with a straight-line airflow through a separation element that uses centrifugal separation to enhance grease and oil separation efficiency, featuring a compact design and easy cleaning, with components like inlet guide devices, separation chambers, and removable collection containers.
Benefits of technology
Achieves over 95% grease particle separation efficiency, reducing environmental pollution by preventing grease and oil from exiting the extractor housing and facilitating easy maintenance.

Abstract
Extractor hood (1) for extracting cooking fumes (2) above a hob (3) by means of an airflow (4), with - a fume hood (5) which has at least one air intake opening (6) and at least one air outlet (7) for the airflow (4), - at least one fan arranged in the exhaust housing (5) to generate the airflow (4), and - at least one separating element (8) arranged in the exhaust housing (5) in the airflow (4) between the air intake opening (6) and the fan for separating one or more components (9) of the cooking fumes (2), in particular fat and / or oil, in the airflow (4), wherein the airflow (4) in the exhaust housing (5) is guided from the air intake opening (6) via the separating element (8) to the fan and is blown out of the exhaust housing (5) by the fan via the air outlet (7), characterized in that the separating element (8) comprises at least one direct current cyclone (10) through which at least a part of the airflow (4) flows in a straight line.
