Abstract
A filter element for an extractor hood includes an odor filter having depressions provided in an entry side of the filter element and extending at least over half of a height of the filter element. A frame holds the odor filter at its edges and has a height which is smaller at least on one side of the frame than a height of the odor filter.
Claims17
A filter element for an extractor hood, said filter element comprising an odor filter having a plurality of parallel, longitudinally extending depressions with depression openings provided in an entry side of the filter element wherein each depression extends vertically at least over half of a height of the filter element resulting in a pleated filter configuration;
- and a frame for holding the odor filter, wherein the odor filter includes a vertically extending side extending longitudinally in parallel with the depressions, wherein the side of the odor filter is adhered to a side of the frame throughout the longitudinal extent of the side of the odor filter, wherein the depressions that are adjacent each side of the frame are open wider than depressions that are not adjacent each side of the frame whereby the pleated filter configuration is asymmetrical.
An extractor hood, comprising:
- a fan for drawing air into the extractor hood;
- at least one filter element for filtering out odorous substances from the air, said filter element for filtering out odorous substances being arranged downstream of the fan in a main flow direction of the fan and including an odor filter provided with a plurality of parallel, longitudinally extending depressions with depression openings in an entry side of the odor filter resulting in a pleated filter configuration, said depressions extending vertically at least over half of a height of the filter element;
- and a frame for holding the odor filter, wherein the odor filter includes a vertically extending side extending longitudinally in parallel with the depressions, wherein the side of the odor filter is adhered to a side of the frame throughout the longitudinal extent of the side of the odor filter, and wherein the depressions that are adjacent each side of the frame are open wider than depressions that are not adjacent each side of the frame whereby the pleated filter configuration is asymmetrical, and
- at least one filter element for filtering out grease and other particulate matter, said filter element for filtering out grease and other particulate matter being arranged upstream of the fan in a main flow direction of the fan, wherein the fan draws air through said filter element for filtering out grease and other particulate matter and wherein the fan blows air through said filter element for filtering out odorous substances.
A filter element for an extractor hood, said filter element comprising an odor filter having depressions provided in an entry side of the filter element and extending at least over half of a height of the filter element and a frame for holding the odor filter, wherein the frame has a height which is smaller at least on one side of the frame than a height of the odor filter.
