Definitions

• Filter module with a filter element and a leaf guard
• the invention relates to a filter module for insertion into a filter housing.
• Filter housing and air ducts are often upstream air conditioners or fans in the vehicle interior.
• filter housings for the air intake filter elements of various kinds are used, for example, to filter out particulate matter, particles and / or unpleasant odors from the intake air. Care must also be taken in the case of engine intake filtration that the air sucked in to the engine of a motor vehicle exhibits sufficiently good purity.
• the invention is therefore based on the object to simplify the installation of a grid and a filter element and to reduce installation costs.
• the filter module comprises a base body, which has a grid and receiving means for a filter element.
• the receiving means allow to use the filter element and the grid as a structural unit together in a filter housing for the air intake.
• the filter element can be attached captive to the grid and anchored at the installation site together with the grid in the filter housing for the air intake. The installer does not have to carry out any reworking on the filter element or on the grille, as these are optimally matched to each other at the factory.
• the Receiving means can be designed such that a correct assignment of a certain filter element in the sense of a "key-lock principle" is ensured to a certain grid.A mesh of a certain mesh size can then be reliably connected to a matching filter element to him This considerably simplifies it.
• the receiving means could be designed as an adhesive or be supplemented by an adhesive.
• an adhesive By an adhesive, the filter element can be applied virtually fixed against displacement directly on the grid.
• the receiving means could be integrally formed on the grid by Anbindestege and have gripping tongues, which protrude from the attachment ridges. In this way, a filter element, such as a flat filter or a flat layer can be clamped to the grid.
• the gripping tongues press the filter element against the grid.
• a frame could be integrally formed, which surrounds the filter element at least partially.
• the frame fulfills two functions. It acts as a guide of the filter module when inserted into the filter housing and prevents tilting of the body in the filter housing. Furthermore, the frame stabilizes the filter element and prevents the formation of leaks through which unfiltered air can pass. The frame can rest under pressure on the filter element.
• the frame could be completely or partially interrupted at a point at which the filter element can be inserted for connection to the base body. This allows the filter element almost like a drawer in introduced a cabinet and thereby guided stable. A deformation, in particular a twist, of the filter element is thereby almost impossible.
• the grid, the base body and the receiving means could be formed of the same material and in one piece. As a result, a low-cost injection molding production of the filter module is possible.
• the main body could be wedge-shaped.
• a wedge-shaped filter element in one direction namely the direction of the taper, be recorded in a secure against displacement. Slipping out of the filter element from the body is thereby almost impossible.
• the main body latching means could be integrally formed for anchoring in a filter housing for the air intake.
• the latching means could include hooks and / or clip fasteners, in particular elastically deformable spring tongues, which cooperate with certain receptacles in the filter housing for the air intake. This also makes it possible to ensure reliable assembly due to a "key-lock principle", namely, if each locking means is assigned a specific receptacle in the filter housing for the air intake.
• a unit could consist of a filter module of the type described here and a filter element of nonwoven fabric, paper, a textile material or other filtering media. To avoid repetition in relation to the inventive step, reference is made to the comments on the filter module as such.
• the filter element could be designed as a folded filter. Wrinkles increase the effective filter area.
• the filter element could be designed as a flat, unfolded position.
• the filter module can be constructed extremely flat building.
• combination filters are used as filter elements which, in addition to particle-separating media, also have odor-adsorbing media, such as activated carbon or zeolites.
