Definitions
- Filter insert with support element for filter medium body that can be locked onto the housing cover
- the invention relates to a filter insert comprising at least one filter medium body through which flow can pass from an inflow surface to an outflow surface, a support element held on the filter medium body, which support element has at least one first locking means by means of which the filter insert can be locked to a housing cover, and a circumferential sealing element which is held on the support element.
- Such a filter insert is known from WO 2016/146250 A1.
- Such filter inserts have been used to date in particular for filtering combustion air in motor vehicles with an internal combustion engine.
- the locking of the filter insert on the housing cover can simplify the replacement of the filter insert.
- US 2010/0162673 A1 describes a filter device with a filter housing and a filter insert arranged in the filter housing so that it can be replaced.
- a pre-filter in the form of a cyclone separator is integrated into a housing cover of the filter housing.
- a filter medium body of the filter insert is surrounded by a support ring near its inflow surface.
- the support ring has tabs that can be moved between a release position and a holding position.
- Recesses are provided in the housing cover, into which the tabs engage in the holding position.
- WO 2016/146250 A1 relates to a filter device, in particular for a motor vehicle, with a filter element which has a filter medium through which a gas can flow for filtering the gas, and with a housing which comprises a housing cover and a filter holder, in the receiving space of which the filter medium can be at least partially accommodated, and with at least one locking device for sealingly connecting the housing cover, filter element and filter holder.
- the locking device enables an upper locking element on the side of the housing cover to be connected to a lower locking element on the side of the filter holder by means of a connecting element on the filter element.
- the upper and lower locking elements are each designed as a locking lug and the connecting element as an upper and a lower closure element, each closure element having a holder into which one of the locking lugs can be at least partially accommodated in a locking position.
- the locking elements are formed on a frame which surrounds the filter medium.
- Two sealing elements are held on the frame, which, when closed, each rest against a sealing surface of the housing cover or the filter holder. Since separate locking elements are provided on the filter element for the filter holder and the housing cover, the opening order of the housing is not predetermined.
- the two aforementioned filter devices are provided with relatively compact filter medium bodies. These are held in the filter housing by the surrounding frame or support ring. In particular, in the case of flat or heavy filter media bodies, lateral fixation may be inadequate in view of the mechanical loads that occur during operation.
- a filter insert is provided.
- the filter insert is basically a gas filter insert, in particular an air filter insert.
- the filter insert is preferably used as part of a filter device according to the invention described below.
- the filter insert has at least one filter medium body through which flow can pass from an inflow surface to an outflow surface.
- the filter medium body is typically cuboid-shaped and through which flow can pass along its smallest dimension.
- the filter insert can therefore also be referred to as a flat filter.
- Such a filter medium body has a low flow resistance with high separation performance and service life.
- the filter insert further comprises a support element held on the filter medium body, which has at least one first locking means, via which the filter insert can be locked to a housing cover.
- the filter insert is locked to the housing cover, which housing cover is part of a filter housing. Gas to be filtered, in particular air, can be guided to the inflow surface of the filter medium body through an inlet on the housing cover.
- the filter insert also has a circumferential sealing element that is held on the support element.
- the sealing element can, on the one hand, seal a dirty side from a clean side (in other words, the inflow surface from the outflow surface). A fluid flow must therefore pass through the filter medium body.
- the sealing element can seal the housing cover from a housing base.
- the support element has a grid section which extends over the outflow surface of the filter medium body and which is integral with the at least one first locking means.
- the grid section typically lies against the outflow surface or extends at a small distance of, for example, a maximum of 2 mm along the outflow surface.
- the grid section provides surface support for the filter medium body. At the same time, the grid section does not impede the flow through the filter medium body, or at least impedes it insignificantly.
- the one-piece design of the support element with the grid section and the at least one first locking means simplifies production.
- the support element with the grid section and the at least one first locking means can in particular be a plastic injection-molded part.
- the monolithic design of the support element ensures that the filter medium body is particularly reliably fixed to the housing cover. Because the filter insert is supported on the outflow side by the grid section and can also be locked to the housing cover, dirt from the dirty side (essentially between the inflow surface and the inlet) does not get to the clean side (into the lower part of the housing) when the filter housing is opened.
- the at least one first locking means can have a locking lug.
- a locking means with a locking lug can be manufactured efficiently and enables reliable fixing and easy release of the filter insert.
- the first locking means is elastically deformable. This further simplifies the fixing and detachment of the filter insert on or from the housing cover.
- the support element and in particular the grid section are typically rigid. This improves the support and fixation of the filter medium body.
- At least two first locking means are formed on two opposite longitudinal sides of the filter insert. This allows a particularly reliable fixation of the filter insert to the housing cover. Typically, all first locking means on the support element are formed in the same way.
- the sealing element can be held permanently on the support element, in particular cast onto the support element.
- a permanent attachment reliably prevents the sealing element from being lost or slipping during assembly. Casting enables efficient production, with the sealing element being automatically connected to the support element during production.
- the support element advantageously has webs with recesses in between, with the sealing element extending through the recesses and encompassing the webs. In this way, a particularly secure fixation of the sealing element, in particular a cast-on one, can be achieved.
- the webs and recesses form a receiving section for the sealing element. This receiving section is also integral with the grid section and the at least one first locking means.
- a protruding sealing edge can be formed on the sealing element, preferably with the sealing edge protruding (in the flow direction) beyond the outflow surface. In the assembled state, the sealing edge can lie sealingly against a sealing surface of the lower housing part.
- a contact surface for sealingly engaging a collar of the housing cover can be formed on the sealing element. The contact surface and the sealing edge are typically arranged opposite one another. The sealing element can then be clamped between the housing cover and the housing base for a particularly reliable seal.
- the at least one filter medium body and the support element can be held together by the sealing element.
- the sealing element thus fulfills a dual function; on the one hand, it serves to seal the filter housing and, on the other hand, to connect the components of the filter insert. This reduces the manufacturing effort.
- the at least one filter medium body can be enclosed by a surrounding frame.
- the frame can seal the filter medium body on its side surfaces so that a flow from the inflow surface to the outflow surface is forced.
- the frame is embedded in the sealing element.
- the frame thus mediates the connection of the filter medium body with the sealing element or the support element.
- the frame protrudes beyond the outflow surface. This allows the frame to be held particularly firmly in the sealing element.
- the frame can comprise or consist of a nonwoven material.
- the frame is made of a nonwoven tape.
- Nonwoven material is inexpensive, easy to process and sufficiently airtight.
- the frame can be a plastic frame, in particular a plastic injection-molded part. This can in particular simplify the fixing of several filter medium bodies.
- the filter insert can have two filter medium bodies through which air can flow in series.
- a first filter medium body has a particle filtration medium and a second filter medium body has an adsorption filter medium, in particular containing activated carbon.
- the second filter medium body is arranged downstream of the first filter medium body.
- Adsorption filter media with activated carbon are comparatively heavy, so that secure support is particularly important, especially when the filter medium body has a large surface area.
- the grid section basically extends along the outflow surface of the downstream filter medium body.
- both filter medium bodies are held on the support element via the sealing element.
- the above-mentioned dual function of the sealing element is thus extended to the fixing of the further filter medium body.
- both filter medium bodies are enclosed by a common frame which is embedded in the sealing element.
- the common frame can be a plastic frame, in particular a plastic injection-molded part.
- the common frame can be injection-molded onto one of the filter medium bodies.
- the other filter medium body can be glued into the common frame. In this way, a particularly stable filter insert can be obtained.
- both filter medium bodies are each enclosed by a surrounding frame, with at least one of the frames being embedded in the sealing element.
- the frames can each comprise a nonwoven material, in particular be made from a nonwoven tape.
- a first embodiment of this filter insert is characterized in that the frame of the first filter medium body in the flow direction extends at least as far as the outflow surface of the second filter medium body in the flow direction, and that the two frames are embedded in the sealing element.
- the frame of the first filter medium body in the flow direction projects beyond the outflow surface of the second filter medium body in the flow direction.
- the frame of the second filter medium body in the flow direction also projects beyond the outflow surface. This simplifies the fixing of the two frames in the sealing element.
- the two frames are glued together. This can be advantageous in terms of the installation space required transversely to the flow direction and can reduce the material required for the sealing element and/or the frames.
- the scope of the present invention also includes a filter device comprising
- a filter housing having a housing cover with an inlet and a housing base with an outlet
- the filter device is basically a gas filter device, in particular an air filter device.
- the lower housing part is typically arranged below the housing cover during use; however, this is not necessarily the case.
- the housing cover and the housing part with the outlet is referred to as the lower housing part.
- the housing cover and the lower housing part enclose a receiving space in which the filter insert can be arranged. Air to be filtered can be guided to the inflow surface of the at least one filter medium body through the inlet on the housing cover and filtered air can be discharged from the outflow surface of the at least one filter medium body through the outlet on the lower housing part.
- the housing cover has at least one second locking means, which is designed to correspond to the at least one first locking means of the filter insert.
- the filter insert can thus be attached to the The filter medium body is supported on the housing cover via the support element, in particular its grid section.
- the housing cover and the housing base can generally be detachably connected to one another via connecting means that are separate from the locking means.
- the housing cover and the housing base can be screwed together.
- Other connections are also conceivable.
- elastic retaining clips can be provided to clamp the housing cover and the housing base against one another.
- the inflow surface of the filter medium body or the upstream filter medium body is assigned to the dirty side in the filter housing.
- the outflow surface of the filter medium body or the downstream filter medium body is assigned to the clean side in the filter housing.
- the filter insert When the filter housing is opened, the filter insert initially remains fixed to the housing cover.
- the sealing element remains in contact with the housing cover as long as the filter insert is locked to the housing cover. Dirt deposited on the raw side cannot therefore fall into the lower part of the housing or reach the clean side.
- the locking mechanism can be released and the filter insert removed from the housing cover. This is best done away from the lower part of the housing.
- the second locking means can be formed with an opening and an edge delimiting the opening.
- a locking lug of the first locking means can engage in the opening and rest on the edge.
- a locking means with an opening and an edge can be produced with particularly little effort and allows a secure connection.
- the opening can make it easier to release the locking when replacing the filter insert.
- the second locking means can be rigid. This makes it possible to make the housing cover rigid overall.
- the first locking means is then elastically deformable in order to be able to bring it into or out of engagement with the second locking means.
- the housing cover and the housing base are sealed against each other in the assembled state by means of the sealing element.
- the sealing element then not only separates the raw side from the clean side, but also prevents air from flowing into or out of the filter housing in the joint between the housing parts.
- the sealing element is advantageously held clamped between the housing cover and the housing base.
- the housing cover can have a circumferential collar for contact with the sealing element.
- the sealing element can have a contact surface against which the collar seals when installed.
- the housing lower part can have a circumferential sealing surface for the sealing element to rest against.
- the sealing element preferably has a sealing edge for sealing contact with the sealing surface.
- the first locking means has an outer leg and an inner leg.
- the lower housing part can have a projection which engages between the legs when the housing cover with the filter insert is placed on the lower housing part. This prevents the filter insert from disengaging when the housing is closed.
- the outer leg is hinged via the inner leg to a receiving section for the sealing element.
- the first locking means can be U-shaped or V-shaped in cross section.
- a filter insert according to the invention described above in particular a filter device according to the invention described above, as a cathode air filter of a fuel cell.
- the invention relates to a fuel cell with an anode and a cathode, between which an electrolyte is arranged, and with a filter device according to the invention described above, through which air can be conducted to the cathode.
- the filter device according to the invention makes this possible both during regular operation (since large filter medium bodies are securely supported on the grid section of the support element and the sealing element ensures reliable separation of the raw and clean sides) and when replacing the filter insert (since the filter insert is initially fixed to the housing cover and remains sealed against it).

- the outer leg 46 with the locking lug 48 can be deflected towards the inner leg 44 or the filter medium body 26.
- Second locking means 50 are provided on the housing cover 14, corresponding to the first locking means 40 of the filter insert 20.
- the second locking means 50 are each formed with an opening 52, which is delimited towards the housing lower part 16 by an edge 54.
- the filter insert 20 separates a raw side 60 corresponding to the inlet 22 from a clean side 62 corresponding to the outlet 24.
- the sealing element 30 is in sealing contact with the collar 56 of the housing cover 14 as well as with a sealing surface 64 of the housing base 16 (hidden in Figure 5, see again Figure 9).
- the sealing element 30 can have a sealing edge 66 for contact with the sealing surface 64. The sealing element 30 thus seals both the two housing parts 14, 16 against each other and the raw side 60 against the clean side 62.
- the two housing parts 14, 16 can be fixed to one another in the closed state by means of screws 67, see Figure 5.
