Embodiment Construction

[0035] in figure 1 A schematic perspective view of an embodiment of the filter element 2 according to the invention is shown therein. The filter element 2 is composed of a frame 23 and a filter 22 accommodated in the frame 23. In the illustrated illustration, the frame 23 is open downwards and upwards, that is to say the frame is formed by only the sides 231 to 234. The odor filter 22 is housed in the frame 23 in such a way that it does not extend beyond the height of the frame 23. In the embodiment shown, the lower side of the frame 23 defines the front side 20 of the filter element 2 and the upper side defines the outlet side 21. The main flow direction of the air is indicated by the arrow S in the drawing.

[0036] The frame 23 defines a rectangular internal space in the illustrated embodiment. An odor filter 22 is arranged in the internal space of the frame 23.

[0037] The odor filter 22 has a flat basic shape. in image 3 A possible structure of the odor filter is shown ...

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.

Description

Technical field [0001] The invention relates to a filter element for a smoke exhaust hood and a smoke exhaust hood. Background technique [0002] Known filter elements in exhaust hoods for filtering or separating odorous substances usually have a structure in which a filter material plate is sheathed with a non-woven fabric, and the filter material plate is composed of a foam material and is loaded with activated carbon. Here, the activated carbon pad can be placed in a plastic frame, on which the non-woven fabric material is welded on the upper and lower sides. [0003] The disadvantage of this known odor filter of the fume hood is that the size of the effective filter surface is small, and the air to be cleaned can enter the filter material mat through the filter surface. However, in order to achieve sufficient cleaning of the odorous air, it is therefore necessary to provide multiple filter elements. However, due to the structural space provided in the fume extraction hood, th...
