Definitions

  • Air filter device for a motor vehicle and filter element for such a filter device Air filter device for a motor vehicle and filter element for such a filter device
  • the invention relates to an air filter device for a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a filter element for an air filter device of a motor vehicle according to the preamble of claim 7.
  • a filter element is arranged in a shaft-like receiving space of a filter housing of the air filter device, which delimits at least one side wall and a base and has an insertion opening closed by a cover, through which the filter element can be introduced into and removed from the receiving space.
  • the insertion opening is arranged on the underside of the receiving space, so that in order to remove the filter element from the receiving space, for example to change the filter element, it comes out of the receiving space automatically via the insertion opening due to gravity after the cover is removed.
  • the insertion opening is arranged differently, for example to the side or above the receiving space, the filter element cannot be easily removed and a disassembly tool may be required. Due to this arrangement of the insertion opening, there are restrictions on the choice of installation space, installation, design of the air filter device and ease of maintenance.
  • the object of the present invention is therefore to provide an air filter device and an associated filter element of the type mentioned, which imposes fewer restrictions on the choice of installation space and installation as well as the design of the air filter device and which also allows for a proper position of the filter element can be detected in the final installation position.
  • the air filter device according to the invention for a motor vehicle comprises a filter element which is arranged in a receiving space of a filter housing of the air filter device, which delimits at least one side wall and a base and has an insertion opening closed by a cover, via which the filter element can be introduced into and removed from the receiving space.
  • At least one spring device is arranged between the side wall and/or the floor of the receiving space and the frame part of the filter element, the spring element of which is elastically compressed in the final installation position of the filter element in the receiving space.
  • the advantage here is that, in contrast to the known air filter device, the receiving space no longer has to be aligned and its insertion opening no longer has to be located underneath it in order to ensure that the filter element can be removed by gravity.
  • other arrangement locations and positions of the filter device and the receiving space can be considered, since, for example, an ergonomically more favorable position of the insertion opening on the top of the receiving space and removal of the filter element against gravity is also possible.
  • the air filter device can be used in particular in a vehicle's ventilation, heating and/or air conditioning system. Other applications in the vehicle are also conceivable.
  • an electrical contact device is arranged between the receiving space and the filter element, which comprises a contact element on the receiving space side and a contact element arranged on the frame part of the filter element on the filter element side, wherein when the spring device is tensioned, the two contact elements come into contact, whereby an electrical signal can be transmitted to a control device of the air filter device.
  • the electrical contact device for example, a correct position of the filter element in the final installation position can be detected.
  • data stored on the filter element side can be detected, for example.
  • the spring device between the filter element and the side wall and/or the floor of the receiving space comprises as elements at least one spring element arranged on the one hand and a counter element arranged on the other hand, in particular a counter surface on which the spring element can be supported in a defined manner.
  • the position or distance and the design of the spring element and the counter element relative to one another are decisive for the spring force with which the filter element is moved out of the receiving space via the insertion opening when the lid is open.
  • the at least one spring element is attached to the side wall and/or the floor of the receiving space.
  • a defined counter surface or similar element on the side of the filter element acts as an abutment for the spring element on the receiving space side in order to achieve a defined spring force with which the filter element is moved out of the receiving space via the insertion opening when the cover is open.
  • the at least one spring element can also be attached to the filter element.
  • a defined counter surface or similar element on the side of the receiving space acts as an abutment for the spring element on the filter element side in order to achieve a defined spring force with which the filter element is moved out of the receiving space via the insertion opening when the cover is open.
  • the insertion opening is arranged on the top side of the receiving space. This makes it possible, for example, to remove the filter element ergonomically.
  • top side refers to the side of the receiving space which, viewed in the direction of gravity, is at a higher level than its bottom.
  • the filter element according to claim 7 has a frame part which surrounds a filter material of the filter element at least in some areas and on which at least one element of a spring device is provided, the spring element of which is elastically compressed in the final installation position of the filter element in the receiving space.
  • the element of the spring device can be either at least one spring element or a counter element, in particular a counter surface, on which the spring element can be supported in a defined manner. The position or distance and the design of the spring element and the counter element relative to one another are decisive for the spring force with which the filter element is moved out of the receiving space via the insertion opening when the cover is open.
  • a contact element of an electrical contact device is arranged on the frame part of the filter element, wherein when the spring device is tensioned, the contact element comes into contact with a contact element provided on the side of the receiving space, whereby an electrical signal can be transmitted to a control device of the air filter device.

  • the filter element 10 has a frame part 14 which surrounds a filter material 16 of the filter element 10 at least in some areas, but here on the outer circumference
  • the frame part 14 is in the present case rectangular in shape with frame parts running parallel to each other, so that it can be easily inserted into the receiving space 12.
  • an essentially rectangular insertion opening 20 of the receiving space 12, adapted to the cross section of the filter element 10, for inserting and removing the filter element 10 can be closed by a cover 22 shown separately in Fig. 2 in a manner explained below.
  • Fig. 4 shows a sectional perspective view of the receiving space 12 of the air filter device with the separately shown cover 22 analogous to Fig. 2, wherein the filter element 10 is introduced into the receiving space 12 via the insertion opening 20.
  • a spring element 24 of a spring device 26 is arranged between the frame part 14 of the filter element 10 and the base 18 of the receiving space 12, which can be tensioned by compression.
  • the spring element 24 is at least essentially not compressed and is not tensioned, as a result of which the filter element 10, which is supported on the spring element 24, for example with a defined counter surface 28 of the frame part 14, protrudes with its upper, outer end 30 from the receiving space 12 via the insertion opening 20. This allows the upper end 30 of the filter element 10 to be removed from the receiving space 12, for example manually.
  • the filter element 10 can be seen in a respective sectional perspective view, now shown in its final installation position within the receiving space 12.
  • the filter element 10 has been pressed further into the receiving space 12, for example manually, beyond the position shown in Fig. 4, whereby the spring element 24 of the spring device 26 arranged between the filter element 10 and the base 18 of the receiving space 12 has been compressed and tensioned.
  • the filter element 10 is thus pushed against the spring force of the spring element 24 that builds up in the installation end position, whereby the insertion opening 20 visible on the upper side of the receiving space 12 has become free.
  • This insertion opening 20 can thus be closed by the cover 22 according to Fig. 6, which is releasably fixed to the receiving space 12, for example via interacting locking elements 32, 34 of a locking device 36.
  • the cover which is now shown in its position fixed to the receiving space 12 according to Fig. 6, the filter element 10 is thus fixed in its final installation position in the receiving space 12 against the spring force of the compressed spring element 24.
  • the filter element 10 could also be fixed in the final installation position on the receiving space 12, for example via a separate locking device or the like, and not by the cover.
  • the one or more spring elements 24 can also be arranged on the side walls 16 of the receiving space and designed differently. The spring element 24 shown is therefore to be understood as an example only.
  • the filter element 10 is pressed out of the receiving space 12 via the insertion opening 20 with the upper, outer end 30 due to the spring force of the tensioned spring element 24 and can thus be manually grasped for complete removal.
  • the arrangement of a corresponding spring device thus enables the filter element 10 to be ejected from the receiving space 12 independently of gravity. This requires a corresponding adjustment of the at least one spring element 24 and its counter surface 28 as elements of the spring device 26, for example to the weight of the filter element 10, the friction between the frame part 14 of the filter element 10 and the side walls 16 of the receiving space 12 and the position of the insertion opening 20.
  • This adjustment is carried out primarily by the suitable design and position of the elements of the spring device 26, namely the spring element 24 and the counter surface 26.
  • the spring element 24 can be arranged on the side of the filter element 10 or the receiving space 12 and the counter surface 26 interacting with the spring element 24 can therefore also be arranged on the side of the filter element 10 or the receiving space 12, for example in the area of the base 18.
  • FIGs. 7 and 8 a further embodiment of the air filter device is shown in respective sectional views, but in the following only the special features and, furthermore, the features already described in connection with the previous embodiment are to be regarded as analogous.
  • the embodiment shown in Figs. 7 and 8 differs in particular in that in the present case two spring elements 24 are provided between the bottom 18 of the receiving space 12 and the frame part 14 of the filter element 10, which are not compressed in Fig. 7 by the corresponding position of the filter element 10 in the receiving space 12 and are compressed in Fig. 8 by the corresponding arrangement of the filter element 10 in the installation end position.
  • an electrical contact device 38 which comprises a schematically indicated contact element 40 on the side of the receiving space and, according to Fig. 9, a filter element-side contact element 42 arranged on the frame part 14 of the filter element 10 shown in a perspective bottom view.
  • the two contact elements 40, 42 come into contact, whereby an electrical signal is generated and can be transmitted, for example, via lines 44 to a control device of the air filter device.
