Description

The present invention relates to an extractor hood.

In the case of extractor hoods, it is known to use filters to clean the air that is sucked in by a fan. For this purpose, on the one hand, liquid and particulate impurities are separated out on the filters. If the extractor hood is to be operated in recirculation mode, odor filters are also used.

The odor filters can represent activated carbon filters, for example. In order to ensure that odorous substances are reliably filtered out, the odor filters must have a large filter surface. For this purpose, pleated filters can be used in which the filter material is in the form of a pleated mat, for example. Compared to filter elements with flat filter material, these filters usually have a higher dead weight. Since the extractor hood is usually mounted on a room ceiling or wall, the user of the extractor hood must insert or remove the filter upside down.

In the FR 2 747 057 A1 describes an extractor hood which has a removable filter on one surface. The surface is formed by a movable plate in which the filter is mounted. The plate can be hinged to a lower part on the hood. The plate has edges that are folded to form upper and lower grooves for holding the filter. The dimensions of the folded edges are such that the filter can be inserted and removed by tilting it when pressed against the bottom of the upper groove.

Other extractor hoods with removable filter elements are, for example, in the EP 1 340 944 A2 , EP 2 581 671 A2 , DE 10 2004 043 069 A1 , CN 106 839 040 A , EP 2 072 906 A2 and EP 1 310 741 A2 described.

It is the object of the present invention to create an extractor hood in which a reliable filtering out of odorous substances can be ensured and which can nevertheless be operated in a simple manner by the user.

The invention is based on the knowledge that this object can be achieved by providing a holder for the odor filter, which at least temporarily guides the odor filter or filters when it is removed or inserted.

The object is therefore achieved by an extractor hood with the features of claim 1.

According to the invention, the extractor hood has a device housing, a fan and at least one odor filter. In addition, the extractor hood preferably has at least one grease filter. The extractor hood can be what is known as a chimney, in which the device housing is a viewing hood that is attached to a room ceiling via a chimney. Alternatively, the extractor hood can also be a ceiling fan in which the device housing is at least partially accommodated in the ceiling of the room. The device housing has a suction opening which, according to the invention, is directed downwards.

Directional information such as above, below, front and rear refer, unless otherwise stated, to an extractor hood and its parts in the assembled state, in which the suction opening is horizontal. In the case of the holding frame, unless otherwise stated, these directions refer to the holding frame in the operating position, in which it is preferably horizontal. Front refers to the side of the extractor hood that faces the user. The side that can be pivoted downward relative to the suction opening is referred to as the front or front edge of the holding frame and its parts.

The suction opening is preferably horizontal. However, it is also possible for the suction opening to be provided in the device housing inclined to the horizontal. At least one fan, which can also be referred to as a fan, is accommodated in the device housing. The fan generates a negative pressure in the device housing through which contaminated air, in particular fumes and vapors, is sucked in become. The opening of the device housing through which air enters the device housing and can reach a fan inlet in the device housing is referred to as the suction opening. The fan inlet represents, for example, an inlet opening on a spiral housing of a radial fan.

According to the invention, the extractor hood has at least one odor filter. The odor filter can be an activated carbon filter. For example, the odor filter can have a pleated filter material that is held in a filter frame. According to the invention, the odor filter can also be a regenerable odor filter.

According to the invention, the extractor hood has a holding frame for the at least one odor filter. In particular, the holding frame has at least one receiving space in which one of the at least one odor filter is detachably received. Part of the receiving space is formed by at least part of a base area of the holding frame. At least one frame opening is formed in the base area. The frame opening denotes an opening in the base area of the holding frame through which air can reach the at least one odor filter in the receiving space.

The odor filter is detachably received in the receiving space. This means that the odor filter can be removed from the receiving space without tools. The odor filter is therefore preferably pushed into the receiving space. An odor filter is particularly preferably provided in each receiving space of the holding frame. The size of the receiving space is dimensioned such that the odor filter can be held in the receiving space in a form-fitting manner, at least on the sides. The odor filter is held down by the base, that is, it is placed on the base.

The holding frame is pivotably mounted on the device housing and, in the operating position, lies in the suction opening of the device housing. The operating position of the holding frame is the position in which the holding frame is located when the extractor hood is in operation. In the operating position, the base of the holding frame forms the underside of the holding frame. The base area of the Holding frame in the operating position in the horizontal. The holding frame can be pivoted from the operating position into an open position. Here, the holding frame is pivoted downward from the operating position in relation to the suction opening. The holding frame is particularly preferably pivotably mounted on the device housing in the vicinity of the rear edge of the holding frame, so that the entire holding frame can be pivoted.

The base of the holding frame preferably represents a flat surface in which the at least one frame opening is made. In the operating position, the holding frame is preferably arranged on the device housing in such a way that the base area of the holding frame faces the incoming air. The holding frame can be made of sheet metal, for example.

In that at least one receiving space for an odor filter is formed on the holding frame and the holding frame is also pivotably mounted on the device housing, a number of advantages can be achieved. On the one hand, the holding frame can be brought into an open position in which the user has access to the at least one odor filter. Due to the pivotable mounting of the holding frame, it is still attached to the device housing in the open position, that is to say the holding frame and thus the odor filter or filters are held on the device housing. The user therefore does not have to bear the weight of the odor filter. This is particularly advantageous since, for example, filters that can be regenerated can have a weight of 1600 g. In the case of an extractor hood in which, for example, three odor filters are provided, the total weight of the odor filters is therefore 4.8 kg. Pleated filters also usually have a weight of 400 g, for example, so that the weight of this type of odor filter is also 1.2 kg. Since the odor filters in the extractor hood according to the invention are held detachably in receiving spaces of the holding frame, they can be removed individually from the corresponding receiving spaces of the holding frame. In addition, pleated or regenerable activated carbon filters or other odor filters can optionally be accommodated in the receiving spaces of the holding frame. The user of the extractor hood can therefore easily retrofit the desired type of odor filter.

According to the invention, the receiving space of the holding frame is formed by at least part of the base area of the holding frame and three holding struts. The holding struts extend perpendicularly from the base of the holding frame. The part of the base of the holding frame which partially forms the receiving space has at least part of a frame opening. In this way, the flow of air onto the odor filter, which is accommodated in the receiving space, can be ensured. The holding struts extend perpendicularly from the base of the holding frame. In the operating position, the holding frame is preferably arranged in such a way that the holding struts are directed upwards from the base of the holding frame, i.e. in the direction of the fan of the extractor hood. The retaining struts can be formed by folding the material of the base surface. Alternatively, however, it is also possible for the holding struts to be separate components that are connected to the base of the holding frame, for example welded. The retaining struts can in particular represent sheet metal strips. Two retaining struts represent the lateral boundaries of the receiving space in the operating position. In addition, one retaining strut represents a front boundary of the receiving space. The receiving space is delimited at the bottom by the base of the retaining frame. Since the receiving space of the holding frame is formed by part of the base area and three retaining struts, this receiving space is open on at least one side on which no retaining strut is provided. This can also be designed to be open on the side of the receiving space opposite the base area, that is to say at the top. Since the receiving space of the holding frame is open on at least one side on which no retaining strut is provided, an odor filter can be pushed into the receiving space in a simple manner. A lateral displacement of the odor filter in the receiving space is prevented by the lateral retaining struts. Moving the odor filter forward is prevented by the front retaining strut.

For easier reference, the open side of the receiving space on which no retaining strut is provided is referred to below as the rear edge of the receiving space. The opposite edge of the receiving space is referred to as the front edge of the receiving space.

The holding struts can be arranged on the edges of the base of the holding frame. In addition, at least one retaining strut in the area of the base of the Be provided holding frame. Such an additional holding strut is preferably parallel to two holding struts which are arranged on opposite lateral edges of the base of the holding frame. In addition, this additional holding strut is perpendicular to the open side of the receiving space on which no holding strut is provided.

Since the receiving space is formed by three retaining webs and at least part of the base area, the odor filter can be prevented from falling out of the receiving space by the front retaining strut when the retaining frame is pivoted, in which the front edge of the retaining frame and thus the receiving space is folded down become.

According to the invention, in addition to the part of the base area and the three retaining struts, the receiving space comprises at least one bend which extends perpendicularly from one of the retaining struts. The bend is also parallel to the base of the holding frame. Such a bend is preferably formed on the front retaining strut which is opposite the open side of the receiving space and extends in the direction of the open side, that is to say to the rear. The recording space is thus additionally limited by such a bend. In addition to the lateral delimitation by retaining struts and a limitation towards the front by a retaining strut, the bend also partially delimits the receiving space in the plane parallel to the base area, that is to say upwards. The length of the bend is less than the length of the base in the direction of the bend. Thus, an odor filter can be pushed into the receiving space from the open side, that is to say from the rear, and is securely held in the receiving space by the bend.

The bend is preferably provided on a retaining strut which is arranged on the front edge of the receiving space. In an open position, the front edge of the receiving space forms the deepest point of the receiving space. The retaining strut provided on the front edge can thus prevent the odor filter from falling out downwards. The bend also prevents the odor filter from tipping out of the receiving space. The Abbug can extend over the entire width of the recording space, that is, over the entire distance from lateral retaining struts, which are perpendicular to the open side of the receiving space, extend.

According to the invention, at least one engagement slot is provided in the bend. This engagement slot extends over the entire length of the bend. Alternatively, several bends can also be arranged next to one another across the width of the holding frame and there can be spaces between the adjacent bends that serve as engagement slots. By providing at least one engagement slot, the user of the extractor hood can access the front edge of the odor filter in the open position of the holding frame and push it backwards in the receiving space, that is to say upwards in the open position. By shifting in this way, the odor filter is pushed out over the open side of the receiving space. As soon as the odor filter is pushed so far that the front edge lies above the end of the bend, the odor filter can also be tilted out of the receiving space, since the bend can no longer hinder this movement. The amount by which the odor filter thus has to be pushed backwards in the receiving space, that is to say upwards in the opening position, is therefore limited to the length of the bend.

According to a preferred embodiment, the holding frame can be held in an open position in which there is an angle of a maximum of 90 ° between the holding frame and the suction opening. The holding frame can be held in the open position by a stop or a suitable design of a hinge. Since the holding frame cannot be pivoted downward by more than 90 ° with respect to the suction opening, the odor filters that are held in the receiving space or spaces can be prevented from falling out.

The angle in the opening position between the holding frame and the suction opening is particularly preferably a maximum of 70 °. In this embodiment, the odor filter is prevented from falling out and additional safeguards, such as a bend, for example, may be dispensed with. However, it is also preferable to provide a bend in this embodiment.

According to one embodiment, at least two receiving spaces are formed in the holding frame. In this case, at least two frame openings are formed in the base area of the holding frame and a frame opening is assigned to each receiving space. A frame opening is preferably located centrally in the part of the base area which forms part of a receiving space. By providing several accommodation spaces, several odor filters can be held in the holding frame. Since, in addition, a frame opening is preferably provided in each receiving space, the reliable flow of air onto the odor filter can be ensured.

According to a preferred embodiment, the holding frame is attached to the device housing via at least one hinge, in particular at least one four-bar hinge. Two hinges are particularly preferably provided, which are arranged on opposite sides of the holding frame. By using a four-bar hinge, on the one hand, secure guidance of the holding frame when the holding frame is pivoted from the operating position into the open position and, on the other hand, secure holding in the open position can be ensured.

The hinge is arranged on the holding frame in the vicinity of the edge of the base area on which no holding strut is provided. The hinge is thus attached near the open side of the receiving space. In this way, the open side of the receiving space is kept at a higher level than the front edge of the receiving space, even in the open position, and the odor filter can be prevented from falling out.

According to one embodiment, the holding frame has a handle and at least one displaceable pin for engagement with the device housing. The handle is preferably arranged on the side of the holding frame which is opposite the pivotable mounting and preferably the hinge. The handle and the pins are thus preferably arranged in the front area of the holding frame. The pins can be displaced parallel to the base of the holding frame. The holding frame can be held in the operating position by the displaceable pins. For this purpose, corresponding openings are provided on the suction opening, into which the pins can be extended. The handle is preferably arranged so that it is accessible to the user in the operating position. The handle is thus preferably in the Base area or provided adjacent to the base area. The handle is preferably provided in a handle strip which adjoins an edge, in particular the front edge, of the base of the holding frame. The grip strip can be designed in one piece with the base area or attached to it. However, it is also within the scope of the invention that the holding frame is held in the operating position by means other than a handle and displaceable pins. For example, a magnetic mounting of the holding frame on the device housing can be provided or a push-push mechanism can be used.

According to one embodiment, at least one grease filter is releasably attached to the device housing in the direction of flow in front of the holding frame. The grease filter or filters are attached to the device housing in such a way that they can be moved separately to the holding frame with respect to the device housing, that is to say can be removed therefrom. Here, for example, handles, magnets or push-push mechanisms, if necessary with rigid or displaceable pins, can be used. Since the filter elements are arranged in front of the holding frame in the direction of flow, they are easily accessible for the user of the extractor hood. Since the grease filters have to be cleaned frequently, this further simplifies the handling of the extractor hood.

According to a further embodiment, a baffle plate is pivotably attached to the device housing in the direction of flow in front of the holding frame. If necessary, one or more grease filters can be provided between the baffle plate and the holding frame. The baffle plate is preferably pivotably attached to the device housing in such a way that its pivoting direction corresponds to the pivoting direction of the holding frame and the pivot axis is in the vicinity of the pivot axis of the holding frame. The angle through which the baffle plate can be pivoted is, however, preferably greater than the angle that lies between the holding frame and the suction opening in the opening position of the holding frame. As a result, the baffle plate does not hinder the pivoting of the holding frame and access to the odor filter in the pivoted position.

In Figure 1 is a schematic, perspective view from below of an embodiment of the extractor hood 1 according to the invention. In the embodiment shown, the extractor hood 1 represents a ceiling fan. The extractor hood 1 has a device housing 10 in which a downwardly directed suction opening 100 is formed. A fan (not visible) is arranged in the device housing 10. A holding frame 14 with three odor filters 13 detachably held therein is arranged in the suction opening 100. The holding frame 14 can also be referred to as a cassette. The suction opening 100 is in the horizontal and the holding frame 14 is in the operating position and is also in the horizontal. From the holding frame 14 is in the view of Figure 1 only its base 140 can be seen. Three frame openings 141 are made in the base area 140, through which some of the odor filters 13, in particular their filter material, can be recognized. In the embodiment shown, the odor filters 13 represent pleated activated carbon filters. The base area 140 of the holding frame 14 is formed by an outer frame 1401 and material strips 1400. In the embodiment shown, two strips of material 1400 are provided, so that three frame openings 141 are formed in the base area 140. In the front area of the holding frame 14, a grip strip 147 is provided, which will be described in more detail later. In the grip strip 147, handles 145 are provided at the lateral ends.

In the embodiment according to Figure 1 a baffle plate 11 is pivotally attached to the device housing 10 on the underside. The baffle plate 11 is attached to the device housing 10 via baffle plate hinges 15. In Figure 1 the baffle plate 11 is shown in the downwardly pivoted position. If the baffle plate 11 is pivoted upwards from this position, there is a suction gap between the baffle plate 11 and the outer edge of the device housing 10, through which air can flow. The size of the baffle plate 11 is larger than the suction opening 100 of the device housing 10, so that air entering via the suction gap reaches the suction opening 100 via an air duct between the underside of the device housing 10 and the baffle plate 11 and can enter the device housing 10 via this.

Figure 2 shows a further schematic, perspective view from below of the embodiment of the extractor hood 1 according to the invention Figure 1 . In Figure 2 the holding frame 14 is shown in the open position. In this case, this is deviated downwards from the suction opening 100 of the device housing 10 about a pivot axis which is located in the rear region of the holding frame and is formed by the hinges 12. In the embodiment shown, two fan inlets 101 are provided in the device housing 10, via which air can reach the fan (s) arranged in the device housing 10.

How out Figure 2 results, the holding frame 14 is attached to the device housing 10 via a four-bar hinge 12. In the embodiment shown, the holding frame 14 has five holding struts, of which only one 142 is visible. The other retaining struts 1420, 143 are in Figure 5 shown. In particular, the lateral holding struts 142, which form the outer lateral edges of the holding frame 14 and which are provided on the lateral edges of the base area 140, are visible. In addition, two central retaining struts 1420 are provided (see Figure 5 ), which extend parallel to the outer lateral retaining struts 142 over the base area 140. The middle retaining struts 1420 are aligned in such a way that they extend along the material strips 1400 the base area 140 extend. A grip strip 147 is provided in the front area of the holding frame 14, which in the open position represents the lower end of the holding frame 14. This extends over the entire width of the base area 140 of the holding frame 14. Slidable pins 146 protrude laterally at the lateral ends of the grip strip 147. These pins 146 are connected to the in Figure 1 handles 145 shown and can be retracted via these handles 145. In the operating position of the holding frame 14, these pins 146 protrude into corresponding pin openings 102 on the device housing 10.

In the embodiment according to Figure 2 a front holding strut (not visible) of the holding frame 14 rests on the rear side of the grip strip 147, that is to say the side facing the base area 140 of the holding frame 14. A bend 144 extends from this front holding strut parallel to the base 140 and in the direction of the rear end of the holding frame 14. In the bend 144, engagement slots 1440 are provided which extend over the entire length of the bend 144. However, it is also within the scope of the invention that the rear of the grip strip 147 supports the front retaining strut 143 (see FIG Figure 4 ) of the holding frame 140 and the bend is provided on the handle bar 147.

In the in Figure 2 The embodiment shown, three receiving spaces 148 for the odor filter 13 are formed. The odor filters 13 each have a filter frame 130, which can be made of plastic, for example, and holds the pleated filter material of the odor filter 13 in shape. The filter frame 130 is also in the Figure 3 to see more closely. In addition, the Figure 3 It can be seen that the receiving space 148 is open to the rear, that is to say that no retaining strut is provided on the rear edge of the retaining frame 14.

In Figure 4 a schematic side view of an embodiment of the holding frame 14 according to the invention is shown. In this view, on the one hand, the front retaining strut 143, on which the grip strip 147 rests, can be seen. On the other hand, in the embodiment shown, a hinge plate 120 is provided, via which the hinge 12 can be fastened to the device housing 10. The embodiment according to Figure 4 differs from the embodiment according to Figures 1 to 3 by the fact that the displaceable pin 146 protrudes in the longitudinal direction of the holding frame 14 beyond its front ends.

In Figure 5 a schematic plan view of the holding frame 14 with odor filters 13 in an extractor hood 1 is shown. In plan view after Figure 5 the receiving spaces 148 for the odor filter 13 can be seen. The receiving spaces 148 are downward through the base (in Figure 5 not visible) limited. The left receiving space 148 is delimited to the left by an outer retaining strut 142 and to the right by a middle retaining strut 1420. To the front, the receiving space 148 is delimited by a front retaining strut 143 which rests against the grip strip 147 or is formed by it. A bend 144, in which engagement slots 1440 are provided, is provided on the front retaining strut 143. The bend 144 has a length which is less than the length of the odor filter 13. The bend 144 thus delimits the left receiving space 148 upwards in the front area. The middle receiving space 148 is downwards through the base area (in Figure 5 not visible) limited. The middle receiving space 148 is delimited on the sides by two middle retaining struts 1420. To the front, the receiving space 148 is delimited by a front retaining strut 143 which rests against the grip strip 147 or is formed by it. At the top, the middle receiving space 148 is also delimited by the bend 144 in the front area. The right receiving space 148 is down through the base (in Figure 5 not visible) limited. The right receiving space 148 is delimited to the left by a central retaining strut 1420. To the front, the receiving space 148 is delimited by a front retaining strut 143 which rests against the grip strip 147 or is formed by it. At the top, the right receiving space 148 is also delimited by the bend 144 in the front area.

With reference to the Figures 6 to 8 The removal of an odor filter 13 from the extractor hood 1 will now be described. First, an optionally provided baffle plate (not shown) is pivoted downwards and any grease filters (not shown) that may be provided are removed from the extractor hood 1. Subsequently, by actuating a handle (not shown) and the associated retraction of pins (not shown) or by releasing the holding frame 14 from the operating position in another way, the holding frame 14 is moved into the position shown in FIG Figure 6 shown opening position brought. In this position, the user can intervene in a Engaging slot 1440 of the bend 144 access the front edge of the odor filter 13 and push it backwards, that is to say upwards in the open position of the holding frame. As soon as the odor filter 13 is in the in Figure 7 is the position shown, in which the front edge of the odor filter 13 is at the end of the bend 144, the user can grip the rear end of the odor filter 13 with the second hand and pull. As a result, the odor filter 13 tilts out of the receiving space 148 away from the base area 140 and, as in FIG Figure 8 shown, can be removed from the receiving space 148.

The present invention thus creates a receptacle for at least one odor filter in a circulating air device. For example, three odor filters can be held by the holding frame by which the receiving spaces are formed and their weight can be securely held on the extractor hood, which can also be referred to as a device.

In addition, the present invention allows the user to remove and reinsert the odor filter conveniently and without tools. This is advantageous because such a filter change is usually necessary every three months.

The holding frame used according to the invention, which can also be referred to as a filter cassette, serves to hold odor filters in the extractor hood. The positions of the odor filters within the holding frame can be specified laterally by holding struts, which can in particular represent metal struts. At the front edge, the odor filters are preferably held in the holding frame by a bend from above.

The holding frame can be attached to the extractor hood by a four-bar hinge, for example, and can be folded down to install and remove the odor filter. This enables the odor filters to be changed in a user-friendly manner. Folding down, which can also be referred to as swiveling open, can, for example, be structurally limited by the hinges to an opening angle of 70 °, as a result of which uncontrolled overshooting of the holding frame is prevented. This also prevents the odor filter from falling out of the holding frame when it is opened.

In the operating position, the holding frame is preferably held by a handle structure on the device housing, for example on an inner frame of the device housing. The handle, which represents a push handle, for example, can be operated with one hand, as a result of which pins, which can also be referred to as tabs, move and release the holding frame for opening, that is, for pivoting downwards. In order to ensure that the pins snap into place in the device housing, they can be pretensioned by springs in the closed position.

5. 5. The user can then remove the odor filters upwards out of the filter frame.
6. 6. To insert the charcoal filter, steps 1.-5. Carried out in reverse order.

The present invention offers a number of advantages. In particular, by creating accommodation spaces on the holding frame, a uniform accommodation of different types of odor filters is created. For example, pleated or regenerable activated carbon filters can be held in the holding frame. This allows the user to easily exchange a pleated filter for a regenerable filter. In addition, the odor filters can be installed and removed without tools, since the odor filters are held in the respective receiving space of the holding frame by means of a form fit. An additional fall protection for regenerable odor filters, such as safety chains, is not necessary.
