Description

[0001] The invention relates to a ceiling-mounted extractor hood according to the preamble of claim 1. A ceiling-mounted extractor hood is defined as an extractor hood that is mounted on or in the ceiling. The extractor hood can therefore also be called a ceiling hood. Examples of such extractor hoods include ceiling fans, island hoods, and wall-mounted hoods.

[0002] Extractor hoods for extracting and filtering moist or greasy cooking fumes, also known as vapors, from cooktops and ovens are known in various designs. The invention relates to a ceiling-mounted extractor hood. These are typically mounted on or in the ceiling and have a baffle plate in front of the actual grease filter. This baffle plate largely covers the intake opening. The baffle plate is positioned at a defined, sufficiently large distance from the grease filter. The vapors are drawn in through a gap formed at the edge of the baffle plate between the baffle plate and the extractor housing. The extractor housing usually contains an air conveying device for extracting the vapors through the exhaust opening.

[0003] An inner frame is typically installed between the baffle plate and the extractor hood housing. This inner frame contributes to the overall stability of the structure and protects the internal components of the extractor hood, such as the air supply system, wiring, and electronics. Because the extracted fumes are regularly directed over the outside of the inner frame, this surface becomes dirty during operation of the extractor hood.

[0004] Further extractor hoods are disclosed in documents DE 10 2009 028 808 A1, DE 10 2009 028 807 A1 and DE 10 2009 059 836 A1.

[0005] The object of the present invention is to find a ceiling-mounted extractor hood in which, in particular, the inner frame is easy for the user to clean.

[0006] The problem is solved by a ceiling-mounted extractor hood with the features of claim 1. Advantageous further developments of the invention are specified in the dependent claims.

[0007] The invention relates to a ceiling-mounted extractor hood comprising a housing, an inner frame with air passage opening, at least one filter element and a baffle plate.

[0008] According to the invention, the inner frame has at least one mounting rail with at least one connection area for detachable connection to the housing. Furthermore, the inner frame has at least one mounting area for a filter element. In the assembled state, the mounting rail is located inside the housing. The inner frame is connected to the housing via the mounting rail. Thus, there are no connecting elements, such as screws or rivets, on the outside of the inner frame. This results in a largely smooth and easily cleanable surface on the outside of the inner frame.

[0009] According to one embodiment of the present invention, a mounting rail is arranged along the longitudinal edge of the air passage opening, and the inner frame can be connected to the housing via the lower leg of the mounting rail. The mounting rail is connected to the inner frame by a material, form, or force-fit connection. "Longitudinal" refers to the longer sides of a rectangular air passage opening. Similarly, "short sides" refers to the shorter sides of a rectangular air passage opening. It is at the discretion of a person skilled in the art to arrange the mounting rails alternatively or additionally along the short sides. Advantageously, the mounting rail is connected to the inner frame in such a way that a smooth surface is maintained on the outside of the inner frame. It is particularly advantageous if the inner frame and mounting rail are designed as a single unit.The inner frame can be connected to the housing via the mounting rail, either by material, form, or force-fit. A particularly advantageous feature is that the mounting rail can be detachably connected to the housing, for example, by means of a screw or clamp connection.

[0010] According to a further development of the present invention, a support bracket is arranged at the broad edge of the air passage opening, which can be connected to the housing via a lower leg and supports the inner frame via an upper leg. It is particularly advantageous if the mounting rails and support brackets extend around the entire edge of the air passage opening, thus effectively shielding the interior of the housing from the extracted air. Furthermore, this measure provides additional stability to the extractor hood.

[0011] In another embodiment, the mounting rails extend completely around the edge of the air vent opening. In this case, the support brackets are not required.

[0012] According to a further development of the present invention, guide vanes for improved airflow to the air passage opening are arranged in a trough-like shape, at least partially in the outer areas of the inner frame. This advantageously prevents the air from becoming turbulent in the 90° angles of the inner frame and thus prevents dirt from accumulating in these areas. Furthermore, the angled air guide vanes are easier to clean.

[0013] According to a further embodiment of the present invention, the baffle plate is hinged to the housing by at least two hinges. In the assembled state, the hinges protrude through cutouts in the inner frame. This allows the baffle plate to be advantageously opened, for example, to clean the outside of the inner frame or the filter elements. If the extractor hood requires maintenance, the inner frame can be detached from the housing and opened via the hinges. In this way, the interior of the housing and its components are easily accessible.

[0014] Further advantages become apparent from the following description of the drawings. The drawings illustrate exemplary embodiments of the invention. The drawings, the description, and the claims contain numerous features in combination. A person skilled in the art will expediently consider the features individually and combine them into meaningful further combinations.

[0015] They show: Fig. 1 an exploded view of a ceiling-mounted extractor hood; Fig. 2 a,b a mounted, ceiling-mounted extractor hood without a baffle plate with (a) and without (b) filter elements inserted; Fig. 3 a mounted, ceiling-mounted extractor hood in the open position.

[0016] Fig. Figure 1 shows an exploded view of a ceiling-mounted extractor hood 101. Shown are a housing 102, two hinges 103, an inner frame 104, four LED modules 105, two support brackets 106, two grease filter elements 107, and a baffle plate 108. To mount the ceiling-mounted extractor hood 101, the hinges 103 and the support brackets 106 are first installed in the housing 102. The LED modules 105 are inserted into the designated cutouts 109 of the inner frame 104. The inner frame 104 with the inserted LED modules 105 is then placed onto the hinges 103 so that they protrude through the designated cutouts 110 on the left and right. The inner frame 104 is then screwed to the housing 102 via the mounting rails 111, which are arranged longitudinally on the edge of the air passage opening.Then the grease filter elements 107 are inserted and the impact plate 108 is connected to the hinges 103, for example by gluing.

[0017] The inner frame 104 houses the LED modules 105 and also serves to hold the grease filter elements. Air guide geometries can also be incorporated into the inner frame 104. Typically, in such devices with perimeter extraction, most of the airflow is drawn in along the long sides. With a simple 90° bend along the long sides, a large portion of the grease in the fumes would accumulate in the resulting corners of the inner frame. Therefore, the inner frame 104 shown features air guide plates 112 along its long sides, which in this case are integrally formed with the inner frame 104. This largely prevents dirt accumulation at the edges and also allows for easy and user-friendly cleaning of the inner frame, especially in the edge areas. Furthermore, this design facilitates easy assembly during manufacturing.

[0018] Fig. Figure 2a shows a mounted, ceiling-mounted extractor hood without a baffle plate, with filter elements inserted and Fig. 2b A mounted, ceiling-mounted extractor hood without a baffle plate and without inserted filter elements. The following are shown in the Fig. 2a and Fig. 2b shows the housing 201, the inner frame 202 with the inserted lighting elements 203. Furthermore, the cutouts 204 for the hinges attached to the housing 201, to which the impact plate (not shown here) is attached, are shown.

[0019] Fig. Figure 2a shows the filter elements 205 used. The user-accessible surface of the extractor hood is flat and has no screws. This gives a tidy impression, and the user can simply wipe the entire surface to clean the interior.

[0020] Fig. Figure 2b shows the extractor hood without grease filter elements. The installation position of the support brackets 206 is shown here. The support brackets are intended to support the inner frame downwards and to cover the interior area of ​​the housing 201 on the left and right. Furthermore, the Fig. 2b The screw points 207 of the inner frame on the housing 201 can be identified. The inner frame is screwed to the housing 201 via the mounting rail.

[0021] Fig.Figure 3 shows a ceiling-mounted extractor hood in its open position. The baffle plate 301 is attached to the hinges 302, which in turn are attached to the housing 303 of the extractor hood. The baffle plate 301 can be opened via the hinges 302. After the filter elements inserted in the inner frame 304 have been removed, the screws securing the inner frame 304 to the housing 303 are loosened. The inner frame 304 can then be opened along the hinges 302.

[0022] This allows customer service or other users easy access to the components inside the 303 housing, such as LED modules or other electrical components and wiring. Therefore, the device does not need to be removed from the ceiling to service internal components. This type of maintenance can be performed directly while the device is installed on the ceiling, thanks to this design principle. Disassembly of the entire device is not required.
