Embodiment Construction

[0042] figure 1 A schematic perspective view of an embodiment of a filter insert 1 is shown. The filter insert 1 has a folded group 3 and a frame 7 . The frame 7 is shown as a square, wherein the lateral boundary surfaces 9 are arranged slightly obliquely. The frame 7 thus has a conical shape and has a trapezoidal cross-section parallel to the fold 5 . It can be seen that the interface 9 is at an angle α to the direction of flow through the fold pack 3 or the filter insert 1 . The angle α is between 10 and 45˚. The frame 7 is formed of plastic, for example. The frame 7 surrounds the folding group 3 laterally in this exemplary embodiment.

[0043] The fold group 3 comprises a filter material folded zigzag as a filter medium. The filter material can be a filter, a non-woven material, which is suitable for filtering raw fluids, such as the air in the vehicle, the outside air or also the combustion air of the vehicle. The folded pack 2 can in this case comprise a multilayer...

Abstract

The invention relates to a filter element (1) with a folded group (3) and a frame (7) at least partially surrounding the folded group (3), wherein the frame (7) has at least one recess (8) for the filter element (1 ) of the raised portion (12) of the housing (10). The receptacle (10) for receiving the corresponding filter insert (1) has at least one projection (12) which engages in the frame (7) when the filter insert (1) is installed in the receptacle (10). inside the gap (8).

Description

technical field [0001] The present invention relates to a filter element, such as an air cleaner for an automobile, and a housing for receiving the filter element. Background technique [0002] Corresponding filter inserts serve to filter flowing fluids or in particular gaseous media, for example for filtering air streams before conveying them into the interior of a motor vehicle. Although it can be used on any filter element and arrangement, the present invention and the problem to be solved are described below for a filter element for filtering the air inside an automobile. Such filters are referred to below for short as vehicle interior air filters or also as interior filters or cabin air filters. [0003] The increased air pollution associated with the use of modern air-conditioning systems in large cities, in particular, makes it desirable and necessary to purify the treated or conditioned air introduced into the vehicle from the outside by means of suitable filters. ...
