Description

[0001] The invention relates to a ventilation device according to the preamble of claim 1.

[0002] A ventilation device of the type mentioned above is generally known, so no specific printed proof is required in this regard. Such a ventilation device consists of a housing, an air duct arranged in the housing, (at least) one filter element arranged in the air duct, and an opening on the air duct that can be sealed airtight with a cover element and is designed for inserting and removing the filter element.

[0003] The invention is based on the objective of improving a ventilation device of the type mentioned above. In particular, a ventilation device that is especially easy to handle, particularly during maintenance, is to be created.

[0004] This problem is solved with a ventilation device of the type mentioned at the outset by the features listed in the characterizing portion of claim 1.

[0005] According to the invention, the filter element and the lid element are connected to each other and designed as a unit that can be inserted and removed together.

[0006] In other words, the ventilation device according to the invention, which is particularly preferably designed as a residential ventilation device, is characterized by the fact that the filter element and the cover element can no longer be used or replaced as separate components to be handled, i.e., one after the other, as before, but now as a complete assembly, which obviously simplifies filter changes and initial assembly considerably.

[0007] Other advantageous embodiments of the ventilation device according to the invention result from the dependent claims.

[0008] The ventilation device according to the invention, including its advantageous further developments according to the dependent claims, is explained in more detail below with reference to the graphic representation of two exemplary embodiments.

[0009] It shows Fig. 1. In perspective, a first embodiment of the ventilation device according to the invention with the housing flap open and the filter element partially extended; Fig. 2. In the future, the ventilation unit according to Fig. 1 with the filter element fully inserted; Fig. 3. In the future, the ventilation unit according to Fig. 1 with the filter element almost fully extended; Fig. 4 from the top, the unit consisting of filter and lid element; Fig. 5. Perspective, as an exploded view, the unit according to Fig. 4; Fig. 6 from the top, the ventilation unit according to Fig. 1; Fig. 7 as a partial section along line BB in Fig. 6 the fully inserted unit consisting of filter and lid element; and Fig. 8. In perspective, a second embodiment of the ventilation device according to the invention, in particular without a housing flap.

[0010] The ventilation device shown in the figures consists, in a known manner, of a housing 1, (at least [here two]) an air duct 2 arranged in the housing 1, (at least [here two]) a filter element 3 arranged in the air duct 2 and an opening 5 on the air duct 3 which can be sealed airtight with a cover element 4 and is designed for inserting and removing the filter element 3.

[0011] The filter element 3 is preferably designed to pneumatically divide the air duct 2 into a duct area before and a duct area after, i.e., air flowing from one end of the air duct 2 to the other must necessarily flow through the filter element 3.

[0012] Furthermore, it is preferably provided that the housing 1 is cuboid in shape and has, in addition to a front 1.1, a rear 1.3, a top 1.4, a bottom 1.5 and two side parts 1.6. It is also preferably provided that the housing 1 is suspended from a building wall by its rear 1.3. Alternatively, the housing 1 can also be arranged on a floor or on a plinth on the floor.

[0013] Essential for the ventilation device according to the invention is that the filter element 3 and the cover element 4 are connected to each other and designed as a unit that can be inserted and removed together.

[0014] Looking at it in more detail, it is preferably intended that the filter element 3 and the lid element 4 are firmly but detachably connected to each other.

[0015] In more detail, it is particularly preferred that the filter element 3 for holding filter material comprises a filter frame 3.1 to which the cover element 4 is attached. It is further preferably provided (see in particular the following): Fig. 5) that the lid element 4 and the filter frame 3.1 are connected to each other by means of a snap-in plug connection.

[0016] Furthermore, how particularly good it looks Fig. As can be seen in Figure 5, it is also preferably provided that a sealing element 3.2, preferably cuboid in shape and preferably made of an elastic material, is arranged between the cover element 4 and the filter frame 3.1, which closes the opening 5 airtight when the ventilation device is operated as intended (i.e., in particular when it is switched on).

[0017] How in particular the comparison of Fig. 1, Fig. As shown in Figures 2 and 3, it is further preferably provided that the (mentioned) unit (consisting of filter element 3 and cover element 4) is designed to be guided in the housing 1 in a drawer-like manner.

[0018] Furthermore, it is preferably provided that the unit can be inserted into and removed from the housing 1 without tools, i.e., in particular by hand.

[0019] In all of this, the filter element 3 preferably has a rectangular base shape, but can also be, for example, trapezoidal, round, semicircular, or square. Furthermore, the filter element 3 is preferably plate-shaped, i.e., an element that is significantly larger in two spatial directions than in a remaining third spatial direction and is at least approximately flat. The filter element 3 is preferably at least twice as long as it is wide and at least five times as wide as it is thick. It is also preferably provided that the filter element 3 is designed to allow airflow in its thickness direction.

[0020] To maximize the available filter area, it is further preferred that the filter element 3 be made of accordion-folded filter material. However, the filter element 3 can also be made of a filter fleece.

[0021] Furthermore, it is preferably provided that the housing 1 has a front face 1.1 and that this front face 1.1 has (at least one) opening 5. With reference to the Fig. 1 to 3, a housing flap 1.2 is further preferably provided on the front 1.1 of the housing 1 to cover the opening 5 which can be closed with the cover element 4. This housing flap 1.2, which in the particularly simple embodiment according to Fig. 8 is missing, and is preferably larger than half, preferably larger than two-thirds, of the area of ​​the front side 1.1 of the housing 1.
