Description

The invention relates to an extractor hood for extracting cooking fumes from above a hob in a downward direction by means of an air flow, with an extractor housing which has at least one air intake opening and at least one air outlet for the air flow, at least one fan arranged in the extractor housing for generating the air flow , at least one separating element arranged in the extractor housing in the air flow between the air intake opening and the fan for separating one or more components of the cooking fumes, in particular fat and / or oil, from the air flow, the separating element being removable from the extractor housing via the air intake opening, the Air flow in the extractor housing is guided in a negative pressure section from the air intake opening via the separating element to the fan and is guided from the fan via an overpressure section in the extractor housing to the air outlet and is blown there out of the extractor housing, and at least one in the extractor housing in the air flow between the Fan and the air outlet arranged in the overpressure section filter element, in particular to reduce odors in the air flow, the filter element being removable from the extractor housing through the air intake opening.

The invention also relates to a combination device with a hob and such an extractor hood.

Such a combination device is out EP 3 789 683 A1 known. The disadvantage of the device described here is the complicated construction and time-consuming handling when changing the filter, so numerous steps are necessary until the filter element can be removed via the air intake opening.

It is therefore the object of the invention to provide an improved extractor hood and an improved combination device which offer a simple construction and uncomplicated handling when changing the filter.

This task is solved by an extractor hood with the features of claim 1.

Characterized in that the separating element is designed with a partition which can be removed together with the separating element from the extractor housing, wherein the separating wall closes an access opening connecting the negative pressure section and the positive pressure section when the separating element is inserted into the extractor housing, the access opening being removed when the separating element is removed If the filter element is released from the extractor housing for its removal through the air intake opening, the filter element can be made easily accessible for changing the filter using a simple design. When changing the filter, the filter element can be easily removed and replaced via the air intake opening, which is otherwise used to suck in cooking fumes during operation. This means that no additional external opening is necessary for changing the filter element in the extractor housing. The air intake opening is easily accessible due to its position on the top of the extractor housing, even when the extractor hood is installed in a kitchen unit. The separating element arranged at the air intake opening can advantageously be removed for cleaning via the air intake opening of the extractor housing. In this way, separated components of the cooking fumes, in particular fat and/or oil, can be easily removed from the separating element. In this context, the filter element, which is arranged in the air flow to reduce odors from cooking fumes, can also be changed in a particularly simple manner. The Air flow is guided in the extractor housing in a negative pressure section from the air intake opening upstream of the fan over the separator element and freed from grease and/or oil. The cleaned air flow is then further sucked in by the fan in the vacuum duct section. The fan then pushes the air flow via the overpressure section in the extractor housing towards the air outlet, with a filter element being provided downstream of the fan in front of the air outlet, in which odor molecules from the cooking fumes are separated from the air flow before the air flow exits the extractor housing at the air outlet. The partition, which can be removed together with the separating element, makes the filter element particularly easy to access. The separating element, which can be removed via the air intake opening, itself forms or includes a partition that closes the access opening when the separating element is inserted into the extractor housing. When the separating element is removed, the partition is also removed at the same time, so that the access opening makes the filter element tangible for its removal. When the separator element is inserted, the partition covers the access opening, so that the negative pressure section and the positive pressure section are separated from one another in an airtight manner. For replacement, a new or regenerated filter element can be inserted through the air intake opening into the extractor housing and through the access opening into its intended location in the overpressure section. The connection between the negative pressure section and the positive pressure section can be closed again simply by inserting the separating element through the air intake opening, since this means that the partition wall completely covers the access opening again. This makes it possible to change the filter element arranged downstream of the fan via the air intake opening of the extractor hood in just a few simple steps.

Advantageous refinements and further developments of the invention result from the dependent claims. It should be noted that the features listed individually in the claims can also be combined with one another in any technologically sensible manner and thus show further refinements of the invention.

According to a preferred embodiment of the invention, it is provided that the access opening allows access to the filter element for its removal through the air intake opening when the separating element is removed from the extractor housing. By removing the separating element, access to the filter element is released, so that the filter element can also be removed via the air intake opening following the removal of the separating element.

Particularly preferred is an embodiment which provides that the filter element has at least one handle element for manually removing the filter element from the extractor housing. The filter element can be easily grasped for removal using the handle element. The handle element can be designed as a recessed grip in the top of the filter element. Several handle elements can also be provided, for example several handle holes in the top of the filter element, so that the filter element can be easily grasped by hand using a tweezer handle and moved upwards through the access opening out of the air intake opening.

A particularly advantageous embodiment of the invention relates to the fact that the filter element can be removed from the extractor housing through the access opening together with the separating element via the air intake opening. The simultaneous removal of the filter element together with the separator element reduces the number of steps required when changing the filter, since the filter element with the separator element can be moved out of the air intake opening together as an interconnected structural unit.

A particularly advantageous embodiment provides that the filter element is connected to the separating element via at least one manually releasable connecting means. Using the manually detachable connecting means, the interconnected structural unit consisting of the filter element and the separating element can be easily separated from each other after they have been removed together through the air intake opening. With the connecting means, the structural unit consisting of the filter element and the separating element can be easily connected to one another before insertion through the air intake opening become. The connecting means can be designed magnetically or as a snap connection or screw connection or plug connection.

A particularly advantageous embodiment of the invention provides that the filter element can be removed from the extractor housing via the negative pressure section through the air intake opening. For cleaning or renewal, a clogged filter element can be removed from the overpressure section through the access opening via the underpressure section through the air intake opening from the extractor housing. To change the filter, a new or regenerated filter element can be inserted through the air intake opening into the extractor housing and via the negative pressure section through the access opening at its intended location in the positive pressure section.

According to an advantageous embodiment of the invention it is provided that the filter element is arranged below the separating element, with the partition forming the underside of the separating element. In this particularly simple embodiment, the underside of the separating element can act as a partition to cover the access opening from above, so that the negative pressure section and the positive pressure section are separated from one another. However, when the separating element is removed upwards via the air intake opening from the extractor housing, the filter element below the separating element is easily accessible from above. The filter can be changed simply by removing the filter element upwards through the access opening and the air intake opening. The new or regenerated filter element is also inserted from above via the air intake opening downwards through the access opening into the overpressure section.

Particularly preferred is an embodiment which provides that the access opening extends below the air intake opening. The filter seat for the filter element in the overpressure channel section is easily accessible from above via the air intake opening arranged above the access opening when the separating element is removed from the extraction housing.

A particularly advantageous embodiment of the invention relates to the separation element being laterally surrounded by a suction chamber of the vacuum section, the access opening being formed in a bottom of the suction chamber. The suction chamber surrounds the separation element laterally, while the partition seals the suction chamber at the bottom. The separating element advantageously adjoins the air intake opening directly in the flow direction of the air flow.

In the separating element, the air flow is preferably divided into two partial air flows and deflected several times through walls in order to separate the components of the cooking fumes, in particular the fat and/or the oil, from the air flow. The deflections of the air flow cause the water drops in the air flow as well as the fat and oil particles of the cooking fumes to be accelerated outwards by centrifugal force and to be pressed against the walls of the separating element and separated. The separating element is preferably cuboid and mirror-symmetrical to a central plane and has two opposite outlets to the suction chamber. As a result, two flow channels are advantageously formed in the separating element, which are formed by two closed side walls oriented parallel to one another. It is also conceivable as a separating element with a partition other separating or filtering devices for separating or filtering out fat and oil particles, such as. B. expanded metal filter. The shape can also differ from the version described here and can, for example, be round or hexagonal or rotationally symmetrical.

The suction chamber of the vacuum section that laterally surrounds the separating element brings the partial air flows from the separating element together to the fan, while the partition wall of the separating element covers the access opening in the bottom of the suction chamber. After the separation element has been removed, the access opening in the bottom of the suction chamber is particularly easily accessible for removing the filter element located underneath.

A particularly advantageous embodiment of the invention provides that the filter element is arranged laterally of the separating element, with the partition forming a side wall of the separating element. In this version, the separating element is closed laterally by a side wall that acts as a partition. The partition wall can thus cover an access opening extending laterally of the separating element and separate the negative pressure section from the positive pressure section. When the separator element is removed via the air intake opening, the side access opening is then accessible for changing the filter element.

An advantageous embodiment of the invention provides that the access opening extends laterally adjacent to the negative pressure section below the air intake opening. The laterally adjacent access opening offers sufficient removal options for changing the filter element and enables a low overall height, since the filter element can be arranged in the overpressure channel section to the side of the separator element. Via the lateral arrangement of the access opening adjacent to the area of the negative pressure section which is located under the air intake opening, the filter element can be moved via the access opening into the area under the air intake opening in order to then simply be lifted upwards over the air intake opening out of the negative pressure section.

Particularly advantageous is an embodiment which provides that the separating element used lies spatially between the fan and the filter element and the fan is connected to the filter element via a channel section of the overpressure section under the separating element and/or to the side of the separating element. The arrangement of the fan and the filter element opposite each other next to the separating element enables a low overall height of the extractor hood. The overall height can be particularly low if the channel section of the overpressure section between the fan and the filter element runs to the side of the separator element. In this case, the underside of the separating element can stand on the floor of the suction chamber, which forms the underside of the extractor housing. The height of the extractor hood can be limited to the height of the separating element. It extends Channel section, on the other hand, under the separating element, the separating element can have a greater lateral length, which enables a high degree of separation even with larger volume flows for the air flow. A channel section running laterally and underneath offers a good compromise that combines both advantages.

An advantageous embodiment of the invention provides that the air flow after the separating element in the negative pressure section is divided into two partial air flows, which are led via two fans into the overpressure section to the filter element and from there are led together to the air outlet and are blown out of the extractor housing there. The use of two fans in the extractor hood significantly increases the possible volume flow of the air flow, so that cooking fumes are better drawn off in a downward direction.

Furthermore, the subject of the invention is a combination device with a hob and an extractor hood arranged on its underside, as described above and in more detail below, the extractor hood being designed as a hob extractor for extracting cooking fumes from above the hob in a downward-pointing direction. The height of the combination device is preferably at most 25 cm, preferably at most 20 cm.

In the Figure 1 Designated by reference number 18, a combination device according to the invention is shown. This combination device 18 includes a Hob 3 and an extractor hood 1 according to the invention arranged on its underside. This extractor hood 1 is designed as a hob extractor for extracting cooking fumes 2 from above the hob 3 in the downward direction 19. When preparing food on the hob 3 in the cookware 20 arranged thereon, the rising cooking fumes 2 are deflected downwards and drawn off via at least one air intake opening 6 of the extractor hood 1. The extractor hood 1 has an extractor housing 5 in which the air intake opening 6 and at least one air outlet 7 for the air flow 4 are located. At least one fan 8 for generating the air flow 4 is also arranged in the extractor housing 5.

The Figure 2 shows a sectional view through the combination device 18 according to Figure 1 . In this illustration it can be seen that a separating element 9 is arranged in the extractor housing 5 of the extractor hood 1 in the air flow 4 between the air intake opening 6 and the fan 8. This separating element 9 serves to separate one or more components of the cooking vapors 2 ( Fig. 1 ), in particular fat and/or oil, from the air stream 4. It can be removed for cleaning via the air intake opening 6, as shown in Figure 3 you can see.

In Figure 3 is a further sectional view through the combination device 18 according to Figures 1 and 2 shown. In this illustration, the separating element 9 is shown removed from the extractor housing 5 of the extractor hood 1 via the air intake opening 6. For this purpose, a guide grille 21 for guiding the air flow 4 through the air intake opening 6 and a cover element 22 that is movably displaceable on the guide grille 21 for influencing the air flow direction are removed from the air intake opening 6. The air flow 4 is guided in the extractor housing 5 in a negative pressure section 10 from the air intake opening 6 via the separating element 9 to the fan 8. For this purpose, a suction chamber 15 surrounds the separating element 9 in the inserted state ( Fig. 2 ) sideways. When inserted, the separating element 9 connects to the air intake opening 6 in the flow direction of the air stream 4. The air stream 4 is advantageously divided into two partial air streams 23 ( Fig. 2 ) divided and deflected several times through walls 24 of the separating element 9 in order to separate the components of the cooking fumes 2, in particular the fat and / or the oil, from the air flow. The Multiple deflection of the air flow 4 causes water drops, fat or oil particles of the cooking vapors in the air flow 4 to be accelerated outwards by centrifugal force and deposited on the walls 24 of the separating element 9. In the example shown here, the separating element 9 is cuboid and mirror-symmetrical to a central plane. The separating element 9 has two opposite outlets 25 to the suction chamber 15. As a result, two flow channels are advantageously formed in the separating element 9, which are delimited by two closed, mutually parallel side walls 26. Alternatively, another separator or filter device for separating or filtering out fat and oil particles, e.g. B. an expanded metal filter can be used. The shape of the separating element 9 can also differ from the embodiment shown here and can, for example, be round or hexagonal or rotationally symmetrical. The suction chamber 15 of the negative pressure section 10, which is arranged on the side of the separating element 9, leads the partial air streams 23 from the separating element 9 together to the fan 8. From the fan 8, the air stream 4 is guided via an overpressure section 11 to the air outlet 7 and is blown there out of the extractor housing 5. In the extractor housing 5, a filter element 12 is arranged in the air flow 4 in the overpressure section 11 between the fan 8 and the air outlet 7, which serves to reduce odors. This can be a filter element 12 with activated carbon, which binds the odor molecules from the cooking fumes 2. This filter element 12 can advantageously be easily removed from the extractor housing 5 via the negative pressure section 10 through the air intake opening 6. For this purpose, according to the invention, the separating element 9 is designed with a partition 13, which can be removed from the trigger housing 5 together with the separating element 9, as in Figure 3 shown. With the separating element 9 inserted, as in Figure 2 shown, the partition 13 on the separating element 9 closes an access opening 14 connecting the negative pressure section 10 and the positive pressure section 11. When the separating element 9 is removed via the air intake opening 6, the access opening 14 is simultaneously released, which provides access to the filter element 12 for its removal the air intake opening 6 offers. This means that there is no additional, external opening in the trigger housing 5 of the Extractor hood 1 or in the hob 3 of the combination device 18 is necessary. The air intake opening 6 is easily accessible in the hob 3 even when the combination device 18 is normally installed in a piece of kitchen furniture (not shown). By cleaning the separating element 9, there is a simple possibility of also changing the filter element 12. The partition 13, which can be removed together with the separating element 9, makes the filter element 12 accessible for this purpose in a particularly simple manner. The separating element 9 itself forms a partition 13, which closes the access opening 14 when the separating element 9, as in Figure 2 can be seen in which the trigger housing 5 is inserted. With the removal of the separating element 9 via the air intake opening 6, the partition 13 is simultaneously removed from the access opening 14 in order to make the filter element 12 accessible for its manual removal.

With the one in the Figures 1 to 3 In the exemplary embodiment shown, the removable filter element 12 is arranged below the separating element 9, with the partition 13 forming the underside of the separating element 9. The access opening 14 extends here below the air intake opening 6. For this purpose, the access opening 14 is located in a bottom 16 of the suction chamber 15 of the vacuum section 10, which laterally surrounds the separating element 9 in the inserted state. The separator element 9 used lies spatially between the fan 8 and the filter element 12 and the fan 8 is connected to the filter element 12 via a channel section 17 which runs under the separator element 9. The filter element 12 can be formed from partial segments that can be removed one after the other via the access opening 14.

The Figure 4 shows a combination device 18 according to the invention in a second embodiment. This combination device 18 also includes a hob 3 and an extractor hood 1 according to the invention arranged on its underside. The extractor hood 1 shown here is also designed as a hob extractor for extracting cooking fumes 2 from above the hob 3 in the downward direction 19. The extractor hood 1 also has an extractor housing 5, in which the air intake opening 6 and at least one air outlet 7 for the air flow 4 are located.

In Figure 5 is a sectional view through the combination device according to Figure 4 with the separating element 9 removed, which, like the guide grid 21, is also shown in section. In this illustration it can be seen that the fan 8 is used to generate the air flow 4 ( Fig. 8 ) preferably has an axis of rotation tilted to the vertical. This allows the air flow 4 to be sucked in from the suction chamber 15 in a particularly space-saving and efficient manner. In this intake chamber 15, the separating element 9 is arranged in the air flow 4 between the air intake opening 6 and the fan 8. This separating element 9 also serves to separate one or more components of the cooking vapors 2 ( Fig. 4 ), in particular fat and/or oil, from the air stream 4 and can be removed for cleaning via the air intake opening 6. The air flow 4 is guided in the extractor housing 5 in the vacuum section 10 from the air intake opening 6 via the separating element 9 through the suction chamber 15 to the fan 8. For this purpose, the suction chamber 15 connects laterally to the separating element 9 in the inserted state. The fan 8 promotes the air flow 4 via an overpressure section 11 to the air outlet 7, where it is blown out of the extractor housing 5. In the overpressure section 11 between the fan 8 and the air outlet 7, a filter element 12 is arranged in the air flow 4, which serves to reduce odors from the cooking fumes. This can preferably be a filter element 12 with activated carbon, which actively binds the odor molecules from the cooking fumes 2. This filter element 12 can also advantageously be easily removed from the extractor housing 5 via the negative pressure section 10 through the air intake opening 6. For this purpose, the separating element 9 has a partition 13, which can be removed from the extractor housing 5 together with the separating element 9. If the separating element 9 is inserted into the extractor housing 5, then the partition 13 on the separating element 9 closes an access opening 14 connecting the negative pressure section 10 and the overpressure section 11. By removing the separating element 9 through the air intake opening 6, the access opening 14 can be opened at the same time, which provides access to the filter element 12 for its removal through the air intake opening 6. An additional, external opening in the extractor housing 5 of the extractor hood 1 or in the hob 3 of the combination appliance 18 is therefore no longer necessary for this. The removable one Separating element 9 itself forms a partition 13, which closes the access opening 14 when the separating element 9, as in Figure 2 can be seen in which the trigger housing 5 is inserted. With the removal of the separating element 9 via the air intake opening 6, the partition 13 is simultaneously removed from the access opening 14 in order to make the filter element 12 accessible for its manual removal. In the exemplary embodiment shown here, the filter element 12 is arranged to the side of the separating element 9. The partition 13 here forms a side wall of the separating element 9. Furthermore, the access opening 14 extends laterally adjacent to the negative pressure section 10 below the air intake opening 6.

In the Figures 6 and 7 It can be seen how the filter element 12 can be removed from the extractor housing 5 via the access opening 14 from the overpressure section 11 through the negative pressure section 10 at the air intake opening 6. For this purpose, the filter element 12 must be released from the filter seat 27 in the overpressure section 11 and tilted slightly. The filter element 12 can then be removed via the access opening 14 through the vacuum section 10. By tilting during removal, larger filter elements 12 can also be placed in the overpressure section 11, which have a cross section that exceeds the cross section of the access opening 14.

The Figure 8 shows a further sectional view of the exemplary embodiment according to Figures 4 to 7 . It can be seen here that the separating element 9 used is located spatially between the fan 8 and the filter element 12. The fan 8 is connected to the filter element 12 via a channel section 17 of the overpressure section 11, the channel section 17 running laterally past the separating element 9. As can be seen, the suction chamber 15 forms a depression in which the separating element 9 is accommodated and which serves as a reservoir for liquids flowing into the extractor hood 1.

In the Figure 9 Designated by reference number 18, a combination device 8 according to the invention is shown in a third embodiment. This combination device 18 also includes a hob 3 and an attached one Extractor hood 1 according to the invention arranged on the underside. This extractor hood 1 is designed as a hob extractor for extracting cooking fumes 2 from above the hob 3 in the downward direction 19. When preparing food on the hob 3 in the cookware arranged on it, the rising cooking fumes 2 are deflected downwards and drawn off via at least one air intake opening 6 of the extractor hood 1. The extractor hood 1 has an extractor housing 5 in which the air intake opening 6 and at least one air outlet 7 ( Fig. 13 ) for the air flow 4 ( Fig. 10 ) is located. In the extractor housing 5 there are also two fans 8 ( Fig. 10 ) to generate the air flow 4 ( Fig. 10 ) arranged. However, only one fan or more than two fans can also be provided.

The Figure 10 shows a sectional view through the combination device 18 according to Figure 9 . In this illustration it can be seen that a separating element 9 is arranged in the extractor housing 5 of the extractor hood 1 in the air flow 4 between the air intake opening 6 and the fan 8. This separating element 9 serves to separate one or more components of the cooking vapors 2 ( Fig. 1 ), in particular fat and/or oil, from the air stream 4. It can be removed for cleaning via the air intake opening 6, as shown in Figure 9 you can see. The air flow 4 is guided in the extractor housing 5 in a negative pressure section 10 from the air intake opening 6 via the separating element 9 to the fan 8. For this purpose, a suction chamber 15 surrounds the separating element 9 laterally when inserted. When inserted, the separating element 9 connects to the air intake opening 6 in the flow direction of the air stream 4. The air stream 4 is advantageously divided into two partial air streams 23 in the separating element 9 and is deflected several times through walls 24 of the separating element 9 in order to separate the components of the cooking vapors 2, in particular the fat and/or the oil, from the air stream. The multiple deflection of the air flow 4 causes water drops, fat or oil particles of the cooking vapors in the air flow 4 to be accelerated outwards by means of centrifugal force and deposited on the walls 24 of the separating element 9.

In Figure 11 is a further sectional view through the combination device 18 according to Figures 9 and 10 shown. In the example shown here that is Separating element 9 is cuboid and mirror-symmetrical to a central plane. The separating element 9 has two opposite outlets 25 to the suction chamber 15. As a result, two flow channels are advantageously formed in the separating element 9, which are delimited by two closed, mutually parallel side walls 26. Alternatively, another separator or filter device for separating or filtering out fat and oil particles, e.g. B. an expanded metal filter can be used. The shape of the separating element 9 can also differ from the embodiment shown here and can, for example, be round or hexagonal or rotationally symmetrical. The air stream 4 is divided into two partial air streams 23 after the separating element 9 in the negative pressure section 10. The suction chamber 15 of the negative pressure section 10, which is arranged on the side of the separating element 9, leads the partial air streams 23 from the separating element 9 to the fans 8. In the extractor housing 5, a filter element 12 is arranged in the air flow 4 in the overpressure section 11 between the fan 8 and the air outlet 7, so that Reduces odors. This can be a filter element 12 with activated carbon, which binds the odor molecules from the cooking fumes 2. In Figure 15 a sectioned detailed view of the filter element 12 can be seen. Here it can be seen that the filter element 12 has a cavity 30 which is surrounded by a filter material frame 31 through which the flow flows from the outside to the inside. The partial air streams 23 are guided via the two fans 8 into the overpressure section 11 to the filter element 12 and from there are guided together to the air outlet and blown out of the extractor housing 5 there. The filter element 12 can advantageously be easily removed from the extractor housing 5 through the air intake opening 6. For this purpose, according to the invention, the separating element 9 is designed with a partition 13, which can be removed from the trigger housing 5 together with the separating element 9, as in Figure 14 shown. With the separating element 9 inserted, as in Figure 11 shown, the partition 13 on the separating element 9 closes an access opening 14 connecting the negative pressure section 10 and the positive pressure section 11 ( Fig. 14 ). When the separating element 9 is removed via the air intake opening 6, the access opening 14 is simultaneously released, which provides access to the filter element 12 for its removal through the air intake opening 6. The When the separating element 9 is removed from the extractor housing 5, the access opening 14 releases the filter element 12 for its removal through the air intake opening 6. This means that no additional, external opening is necessary in the extractor housing 5 of the extractor hood 1 or in the hob 3 of the combination appliance 18. The air intake opening 6 is easily accessible in the hob 3 even when the combination device 18 is normally installed in a piece of kitchen furniture (not shown). By cleaning the separating element 9, there is a simple possibility of also changing the filter element 12. The partition 13, which can be removed together with the separating element 9, makes the filter element 12 accessible for this purpose in a particularly simple manner. The separating element 9 itself forms a partition 13, which closes the access opening 14 when the separating element 9, as in Figure 11 can be seen in which the trigger housing 5 is inserted. With the removal of the separating element 9 via the air intake opening 6, the partition 13 is simultaneously removed from the access opening 14 in order to make the filter element 12 accessible for its manual removal. With the one in the Figures 9 to 11 In the exemplary embodiment shown, the removable filter element 12 is arranged below the separating element 9, with the partition 13 forming the underside of the separating element 9. The access opening 14 extends here below the air intake opening 6. For this purpose, the access opening 14 is located in a bottom 16 of the suction chamber 15 of the vacuum section 10, which laterally surrounds the separating element 9 in the inserted state. The separator element 9 used lies spatially between the fans 8 and above the filter element 12 and the fans 8 are connected to the filter element 12 via a channel section 17 which runs under the suction chamber 15. The filter element 12 can be formed from partial segments that can be removed one after the other via the access opening 14 or the filter element 12 can be removed in one piece via the access opening 14.

As in Figure 12 can be seen, the filter element has handle elements 28 for manual removal of the filter element 12. These handle elements 28 are also shown in the individual view Figure 17 to see. The filter element 12 can be easily grasped for removal via the handle elements 28. The handle elements 28 are shaped as a recessed grip in the top of the filter element 12. The filter element 12 can be as in Figure 14 is easy to recognize Grasp the hand with the handle of tweezers and move it upwards through the access opening 14 out of the air intake opening 6. The filter element 12 can also be removed from the extractor housing 5 together with the separating element 9 via the air intake opening 6. With the simultaneous removal of the filter element 12 together with the separating element 9, the number of steps required when changing the filter is reduced, since the filter element 12 with the separating element 9 can be moved out of the air intake opening 6 as an interconnected structural unit. The filter element 12 can be connected to the separating element 9 via at least one manually releasable connecting means 29. Several connecting means 29 can preferably be provided. The connecting means 29 are in the Figure 16 to see. Using the manually detachable connecting means 29, the interconnected structural unit consisting of filter element 12 and separating element 9 can be easily separated from one another after they have been removed together through the air intake opening. By means of the connecting means 29, the structural unit consisting of filter element 12 and separating element 9 can be easily connected to one another before insertion through the air intake opening 6. The connecting means 29 are designed as magnets, so that the filter element 12 is releasably attached to the magnetic separation element 9. The filter element 12 used lies spatially between the fans 8 and under the separating element 9 and the fans 8 are connected via a channel section 17 which is under the suction chamber 15 ( Fig. 11 ) runs, connected to the filter element 12.

The Figure 13 shows a rear view of the combination device 18 according to the Figures 9 to 12 . In this view you can see the air outlet 7, through which the air flow 4 ( Fig. 10 ) is blown out of the trigger housing 5. Another post-filter (not shown) can be connected to the air outlet for recirculating air operation. Otherwise, the air flow can be diverted from the kitchen to the outside via a wall connection (not shown). For this purpose, an air duct (not shown) is provided between the air outlet 7 and the wall connection.

In Figure 14 is a further sectional view through the combination device 18 according to Figures 9 to 13 shown. In this representation it is Separating element 9 is shown removed via the air intake opening 6 from the extractor housing 5 of the extractor hood 1. For this purpose, the guide grille 21 for guiding the air flow 4 through the air intake opening 6 and a cover element 22 that is movably displaceable on the guide grille 21 for influencing the air flow direction are removed from the air intake opening 6. The separating element 9 is therefore accessible and can be removed manually upwards via the air intake opening 6, as shown. The separating element 9 is removed together with the partition 13 from the extractor housing 5. When the separating element 9 is removed via the air intake opening 6, the access opening 14 is simultaneously released, which provides access to the filter element 12 for its removal through the air intake opening 6. In Figure 9 It can be seen how the filter element 12 can be removed from the overpressure section 11 through the air intake opening 6 from the extractor housing 5 via the access opening 14. For this purpose, the filter element 12 must be released from the filter seat 27 in the overpressure section 11. The filter element 12 can then be removed via the access opening 14.
