Description

[0001] The invention relates to a cooker hood for extracting cooking fumes from above a cooktop in a downward direction by means of an airflow, comprising a hood housing having at least one air intake opening and at least one air outlet for the airflow, at least one fan arranged in the hood housing for generating the airflow, and at least one separating element arranged in the hood housing in the airflow between the air intake opening and the fan for separating one or more components of the cooking fumes, in particular grease and / or oil, from the airflow, wherein the separating element can be removed from the hood housing via the air intake opening, wherein the airflow in the hood housing is guided in a negative pressure section from the air intake opening via the separating element to the fan and is guided by the fan via a positive pressure section in the hood housing to the air outlet and blown out of the hood housing there.and at least one filter element arranged in the exhaust housing in the airflow between the fan and the air outlet in the positive pressure section, in particular for reducing odors in the airflow, wherein the filter element can be removed from the exhaust housing through the air intake opening.

[0002] Furthermore, the invention relates to a combination device with a cooktop and such a range hood.

[0003] Such a combination device is known from EP 3 789 683 A1. A disadvantage of the device described here is its complicated construction and the cumbersome handling required for filter changes; numerous steps are necessary before the filter element can be removed through the air intake opening.

[0004] The EP 3 390 918 B1, DE 10 2017 223 828 A1, WO 2017 / 089 925 A1, EP 3 722 677 A1 and DE 10 2020 210 564 A1 disclose various other designs of cooking extractor devices with filter changing devices.

[0005] It is therefore the object of the invention to provide an improved extractor hood and an improved combination device that offer a simple design and uncomplicated handling when changing the filter.

[0006] This problem is solved by a cooker hood with the features of claim 1.

[0007] Because the filter element is designed with a partition that can be removed from the extractor housing along with the filter element, and because the partition closes an access opening connecting the negative pressure and positive pressure sections when the filter element is inserted into the extractor housing, and because this access opening releases the filter element for removal through the air intake opening when the separator element is removed from the extractor housing, the filter element can be easily accessed for filter replacement with a simple design. The filter element can thus be easily removed and replaced via the air intake opening, which is otherwise used to draw in cooking fumes during operation. This eliminates the need for an additional external opening in the extractor housing for changing the filter element.The air intake opening, due to its position on the top of the extractor housing, is easily accessible even when the extractor hood is installed in a kitchen cabinet. The separator element located at the air intake opening can conveniently be removed for cleaning via the air intake opening of the extractor housing. This allows for the easy removal of separated cooking fumes, particularly grease and / or oil, from the separator element. At the same time, the filter element, which reduces cooking odors in the airflow, can also be replaced with exceptional ease. Within the extractor housing, the airflow is guided in a negative pressure section from the air intake opening upstream of the fan, over the separator element, and freed of grease and / or oil. The cleaned airflow is then drawn in by the fan in the negative pressure duct section.The fan then pushes the airflow through the positive pressure section in the extractor housing towards the air outlet. Downstream of the fan, a filter element is located before the air outlet. This filter element removes odor molecules from the cooking fumes before the airflow exits the extractor housing at the air outlet. The removable partition, which comes with the filter element, provides particularly easy access to the filter element. The filter element, which can be removed through the access opening, either forms itself or includes a partition that seals the access opening when the filter element is inserted into the extractor housing. Therefore, removing the filter element also removes the partition. When the filter element is in place, the partition covers the access opening, ensuring an airtight separation between the negative pressure and positive pressure sections.For replacement, a new or refurbished filter element can be inserted into the extractor housing through the air intake opening and into its designated position in the positive pressure section through the access opening. The connection between the negative pressure and positive pressure sections can be easily closed again by inserting the filter element through the air intake opening, as this ensures the partition completely covers the access opening once more. This allows for quick and easy replacement of the filter element located downstream of the fan via the extractor hood's air intake opening.

[0008] Advantageous embodiments and further developments of the invention are described in the dependent claims. It should be noted that the features listed individually in the claims can also be combined in any technologically meaningful way, thus revealing further embodiments of the invention.

[0009] According to a preferred embodiment of the invention, the access opening, when the separator element has been removed from the exhaust housing, provides access to the filter element for its removal through the air intake opening. Removing the separator element releases access to the filter element, so that the filter element can then also be removed through the air intake opening.

[0010] A particularly preferred embodiment provides that the filter element has at least one handle for manually removing the filter element from the fume hood housing. The filter element can be easily grasped for removal using the handle. The handle can be designed as a recessed grip in the top of the filter element. Advantageously, the at least one handle is formed in the partition. Multiple handles can also be provided, for example, several recessed grips in the top of the filter element, so that the filter element can be easily grasped by hand using a pincer grip and moved upwards through the access opening from the air intake.

[0011] A particularly advantageous embodiment of the invention relates to the fact that the filter element, together with the separator element, can be removed from the exhaust housing through the access opening via the air intake opening. The simultaneous removal of the filter element and the separator element reduces the number of steps required when changing the filter, since the filter element and the separator element can be moved out of the air intake opening together as a connected unit.

[0012] A particularly advantageous embodiment provides that the filter element is connected to the separator element via at least one manually releasable connecting element. The manually releasable connecting element allows the connected assembly of filter element and separator element to be easily separated after joint removal through the air intake opening. The connecting element allows the assembly of filter element and separator element to be easily connected before insertion through the air intake opening. The connecting element can be magnetic, a snap-fit ​​connection, a screw connection, or a plug connection.

[0013] A particularly advantageous embodiment of the invention provides that the filter element can be removed from the fume hood via the negative pressure section through the air intake opening. For cleaning or replacement, a clogged filter element can be removed from the positive pressure section through the access opening, via the negative pressure section, and through the air intake opening of the fume hood. For filter replacement, a new or regenerated filter element can be inserted into the fume hood through the air intake opening and, via the negative pressure section, through the access opening in its designated position in the positive pressure section.

[0014] According to an advantageous embodiment of the invention, the filter element is arranged below the separator element, with the partition forming the top of the filter element. In this particularly simple embodiment, the top of the filter element can act as a partition, covering the access opening, thus separating the negative pressure and positive pressure sections. When the separator element is removed upwards from the fume hood via the air intake opening, the filter element below the separator element is easily accessible from above. Filter replacement can therefore be carried out simply by removing the filter element, including the partition, upwards through the access opening and the air intake opening. The new or regenerated filter element is also inserted from above, through the air intake opening, downwards through the access opening into the positive pressure section until the partition covers the access opening.

[0015] A particularly preferred embodiment provides that the access opening extends below the air intake opening. The filter seat for the filter element in the overpressure duct section is easily accessible from above via the air intake opening located above the access opening when the separating element has been removed from the exhaust housing.

[0016] A particularly advantageous embodiment of the invention relates to the separating element being laterally surrounded by an intake chamber of the vacuum section, the access opening being formed in the base of the intake chamber. The intake chamber surrounds the separating element laterally, while the partition seals the intake chamber at the bottom. Advantageously, the separating element connects directly to the air intake opening in the direction of airflow.

[0017] In the separating element, the airflow is preferably divided into two partial airflows and deflected multiple times by walls to separate the components of the cooking fumes, in particular the fat and / or oil, from the airflow. The deflections of the airflow cause the water droplets and the fat and oil particles of the cooking fumes in the airflow to be accelerated outwards by centrifugal force and pressed against the walls of the separating element, where they are separated. The separating element is preferably cuboid in shape and mirror-symmetrical about a central plane and has two opposing outlets to the intake chamber. This advantageously creates two flow channels in the separating element, formed by two closed, parallel side walls. Other separating or filtering devices for separating or filtering fat and oil particles, such as [examples of other separating or filtering devices], are also conceivable as separating elements.Expanded metal filters are used. The shape can also differ from the design described here and may be, for example, round, hexagonal, or rotationally symmetrical.

[0018] The intake chamber of the vacuum section, which surrounds the separator element laterally, directs the partial airflows from the separator element to the fan, while the partition of the filter element covers the access opening in the bottom of the intake chamber. After removing the separator element, the access opening in the bottom of the intake chamber is particularly easy to reach, allowing for the removal of the filter element and its partition located below.

[0019] A particularly advantageous embodiment of the invention provides that the filter element is arranged laterally to the side of the separator element, with the partition forming a side wall of the filter element. In this embodiment, the filter element is laterally closed by a side wall acting as a partition. This partition can cover an access opening extending laterally to the separator element and separate the negative pressure section from the positive pressure section. When the separator element is removed via the air intake opening, the lateral access opening is then accessible for replacing the filter element along with the partition.

[0020] An advantageous embodiment of the invention provides that the access opening extends laterally adjacent to the negative pressure section below the air intake opening. This laterally adjacent access opening offers sufficient removal space for changing the filter element and allows for a low overall height, since the filter element can be arranged laterally to the side of the separator element in the positive pressure channel section. Due to the lateral arrangement of the access opening adjacent to the area of ​​the negative pressure section located below the air intake opening, the filter element can be moved through the access opening into the area below the air intake opening and then simply lifted out of the negative pressure section, with the partition facing upwards, through the air intake opening.

[0021] A particularly advantageous embodiment provides that the separator element is located spatially between the fan and the filter element, and that the fan is connected to the filter element via a duct section of the positive pressure section, either below the separator element and / or to the side of the separator element. The arrangement of the fan and the filter element opposite each other, each next to the separator element, allows for a low overall height of the extractor hood. The overall height can be even lower if the duct section of the positive pressure section between the fan and the filter element runs to the side of the separator element. In this case, the underside of the separator element can rest on the floor of the intake chamber, which forms the underside of the extractor housing. Thus, the overall height of the extractor hood can be limited to the height of the separator element.If, however, the duct section extends below the separator element, the separator element can have a greater lateral length, enabling a high separation efficiency even with larger airflow volumes. A duct section running laterally and underneath offers a good compromise, combining the advantages of both.

[0022] An advantageous embodiment of the invention provides that the airflow after the separator element in the negative pressure section is split into two partial airflows, which are guided by two fans into the positive pressure section to the filter element and from there together to the air outlet, where they are blown out of the extractor housing. The use of two fans in the extractor hood significantly increases the possible volume flow of the airflow, so that cooking fumes are extracted more effectively in a downward direction.

[0023] Furthermore, the invention relates to a combination appliance comprising a cooktop and a range hood arranged on its underside, as described above and below, wherein the range hood is designed as a cooktop extractor for extracting cooking fumes from above the cooktop in a downward direction. Preferably, the height of the combination appliance is at most 25 cm, more preferably at most 20 cm.

[0024] Further features, details, and advantages of the invention will become apparent from the following description and the drawings, which show exemplary embodiments of the invention. Corresponding objects or elements are provided with the same reference numerals in all figures. The figures show: Fig. 1 Combination device according to the invention with extractor hood in first embodiment, Fig. 2 Sectional view through the combination device, Fig. 3 further sectional views through the combination device, Fig. 4 Sectional view through the filter element, Fig. 5 Rear view of the combination device, Fig. 6 Sectional view through the combination device with the separating element removed, Fig. 7.

[0025] In the Fig. Figure 1, designated by reference numeral 18, shows a combination appliance according to the invention in a first embodiment. This combination appliance 18 comprises a cooktop 3 and a range hood 1 according to the invention arranged on its underside. This range hood 1 is designed as a cooktop extractor for extracting cooking fumes 2 from above the cooktop 3 in a downward direction 19. Thus, when food is prepared on the cooktop 3 in the cookware placed thereon, the rising cooking fumes 2 are deflected downwards and extracted via at least one air intake opening 6 of the range hood 1. The range hood 1 has an extractor housing 5 in which the air intake opening 6 and at least one air outlet 7 ( Fig. 5) for airflow 4 ( Fig. 2). The exhaust housing 5 also contains two fans 8 ( Fig. 2) to generate the airflow 4 ( Fig. 2) arranged. However, it is also possible to have only one fan or more than two fans.

[0026] The Fig. Figure 2 shows a sectional view through the combination device 18 according to Fig. 1. This illustration shows that a separating element 9 is arranged in the airflow 4 between the air intake opening 6 and the fan 8 in the exhaust housing 5 of the extractor hood 1. This separating element 9 serves to separate one or more components of the cooking fumes 2 ( Fig. 1), in particular grease and / or oil, from the airflow 4. It can be removed for cleaning via the air intake opening 6, as shown in Fig. Figure 1 shows the airflow 4 being guided in the exhaust housing 5 through a negative pressure section 10 from the air intake opening 6, via the separator element 9, to the fan 8. For this purpose, an intake chamber 15 surrounds the separator element 9 laterally when installed. In its installed state, the separator element 9 connects to the air intake opening 6 in the direction of airflow 4. Advantageously, the airflow 4 is divided into two partial airflows 23 within the separator element 9 and deflected multiple times by walls 24 of the separator element 9 to separate the components of the cooking fumes 2, in particular the fat and / or oil, from the airflow. This multiple deflection of the airflow 4 causes water droplets, fat, or oil particles from the cooking fumes to be accelerated outwards by centrifugal force and deposited on the walls 24 of the separator element 9.

[0027] In Fig. Figure 3 is another sectional view through the combination device 18 according to the Fig. 1 and Fig. Figure 2 shows the following example. In this example, the separating element 9 is cuboid and mirror-symmetrical about a central plane. The separating element 9 has two opposing outlets 25 leading to the intake chamber 15. Advantageously, this results in two flow channels within the separating element 9, which are delimited by two closed, parallel side walls 26. Alternatively, another separating or filtering device for separating or filtering grease and oil particles, e.g., an expanded metal filter, can be used as the separating element 9. The shape of the separating element 9 can also differ from the embodiment shown here and may, for example, be round, hexagonal, or rotationally symmetrical. After the separating element 9, the airflow 4 is split into two partial airflows 23 in the negative pressure section 10.The intake chamber 15 of the negative pressure section 10, arranged laterally to the separating element 9, directs the partial airflows 23 from the separating element 9 to the fans 8. In the exhaust housing 5, a filter element 12 is arranged in the airflow 4 in the positive pressure section 11 between the fan 8 and the air outlet 7. This filter element serves to reduce odors. It can be a filter element 12 containing activated carbon, which binds the odor molecules from the cooking fumes 2. Fig. Figure 7 shows a cutaway detail view of the filter element 12. It can be seen that the filter element 12 has a cavity 30 surrounded by a filter material frame 31, through which air flows from the outside to the inside. The partial airflows 23 are guided via the two fans 8 into the positive pressure section 11 to the filter element 12 and from there together to the air outlet, where they are blown out of the exhaust housing 5. Advantageously, the filter element 12 can be easily removed from the exhaust housing 5 through the air intake opening 6. According to the invention, the filter element 12 is designed with a partition 13 for this purpose, which can be removed from the exhaust housing 5 together with the filter element 12, as shown in Figure 7. Fig. 1 shown. With filter element 12 inserted, as in Fig. As shown in Figure 6, the partition 13 on the filter element 12 closes an access opening 14 connecting the negative pressure section 10 and the positive pressure section 11 ( Fig. 6) Thus, when the separator element 9 is removed via the air intake opening 6, the access opening 14 is simultaneously released, providing access to the filter element 12 for its removal through the air intake opening 6. When the separator 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. Therefore, no additional external opening is required in the extractor housing 5 of the extractor hood 1 or in the cooktop 3 of the combination appliance 18. The air intake opening 6 in the cooktop 3 is also easily accessible in the standard installation state of the combination appliance 18 in a (not shown) kitchen cabinet. Cleaning the separator element 9 provides a simple opportunity to also replace the filter element 12. The partition 13, which can be removed together with the filter element 12, makes the filter element 12 particularly easy to access for this purpose.Thus, the filter element 12 itself forms a partition 13 that closes the access opening 14 when the filter element 12, as in . Fig. 6 can be seen, into which the exhaust housing 5 is inserted. By removing the separating element 9 via the air intake opening 6, the partition 13 in front of the access opening 14 is simultaneously made accessible in order to grasp the filter element 12 for its manual removal. In the Fig. 1, Fig. 2 to Fig. In the embodiment shown in Figure 3, the removable filter element 12 is arranged below the separator element 9, with the partition 13 forming the top surface of the filter element 12. The access opening 14 extends below the air intake opening 6. The access opening 14 is located in a base 16 of the intake chamber 15 of the vacuum section 10, which surrounds the separator element 9 laterally when installed. The installed separator element 9 is positioned between the fans 8 and above the filter element 12, and the fans 8 are connected to the filter element 12 via a duct section 17 that runs below the intake chamber 15. The filter element 12 can be formed from segments that can be removed one after the other via the access opening 14, or the filter element 12 can be removed as a single unit via the access opening 14.

[0028] As in Fig. As can be seen in Figure 4, 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 according to Figure 4. Fig. 9 can be seen. The filter element 12 can be easily grasped for removal using the handle elements 28. The handle elements 28 are shaped as a grip recess in the top of the filter element 12, which forms the partition 13. The filter element 12 can thus be removed, as also in Fig. The filter element 12, which can be easily grasped by hand using pincer grips, can be moved upwards through the access opening 14 from the air intake opening 6. The filter element 12 can also be removed from the exhaust housing 5 together with the separator element 9 via the air intake opening 6. Removing the filter element 12 and separator element 9 simultaneously reduces the number of steps required for filter changes, as the filter element 12 and separator element 9 can be moved together as a connected unit from the air intake opening 6. The filter element 12 can be connected to the separator element 9 by at least one manually releasable connecting element 29. Preferably, several connecting elements 29 are provided. The connecting elements 29 are located in the Fig. 8 can be seen. The interconnected assembly consisting of filter element 12 and separator element 9 can be easily separated after being removed together through the air intake opening by means of the manually releasable connecting elements 29. The assembly consisting of filter element 12 and separator element 9 can also be easily connected to each other by means of the connecting elements 29 before insertion through the air intake opening 6. The connecting elements 29 are designed as magnets so that the filter element 12 is detachably attached to the magnetic separator element 9. The inserted filter element 12 is located spatially between the fans 8 and below the separator element 9, and the fans 8 are connected via a duct section 17, which is located below the intake chamber 15 ( Fig. 3) runs, connected to the filter element 12.

[0029] The Fig. Figure 5 shows a rear view of the combination device 18 according to the Fig. 1, Fig. 2, Fig. 3 to Fig. 4. In this view, the air outlet 7 can be seen, through which the airflow 4 ( Fig. 2) is blown out of the extractor housing 5. For recirculation mode, an additional (not shown) post-filter can be connected to the air outlet. Otherwise, the airflow can be routed from the kitchen to the outside via a (not shown) wall connection. For this purpose, an air duct (not shown) is provided between the air outlet 7 and the wall connection.

[0030] In Fig. Figure 6 is another sectional view through the combination device 18 according to the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. Figure 5 shows the separation element 9 being removed from the exhaust housing 5 of the extractor hood 1 via the air intake opening 6. For this purpose, the guide grille 21, which directs the airflow 4 through the air intake opening 6, and a cover element 22, which is movable on the guide grille 21 and influences the airflow direction, have been removed from the air intake opening 6. This makes the separation element 9 accessible, and it can be manually removed upwards through the air intake opening 6, as shown. Removing the separation element 9 through the air intake opening 6 simultaneously opens the access opening 14, which provides access to the filter element 12 for its removal through the air intake opening 6. The filter element 12 is thus removed from the exhaust housing 5 together with the partition 13. Fig. Figure 1 shows how the filter element 12 can be removed from the overpressure section 11 through the air intake opening 6 in the exhaust housing 5 via the access opening 14. For this, the filter element 12 must be detached from the filter seat 27 in the overpressure section 11. The filter element 12 can then be removed via the access opening 14.

[0031] In the Fig. Figure 10, designated by reference numeral 18, shows a second embodiment of the combination appliance according to the invention. This combination appliance 18 comprises a cooktop 3 and a range hood 1 according to the invention arranged on its underside. This range hood 1 is designed as a cooktop extractor for extracting cooking fumes from above the cooktop 3 in a downward direction 19. Thus, when food is prepared on the cooktop 3 in the cookware placed on it, the rising cooking fumes 2 are deflected downwards and extracted via at least one air intake opening 6 of the range hood 1. The range hood 1 has a housing 5 in which the air intake opening 6 and at least one air outlet (on the rear or underside) for the airflow 4 are located. At least one fan 8 for generating the airflow 4 is also arranged in the housing 5.This illustration shows that a separating element 9 is arranged in the airflow 4 between the air intake opening 6 and the fan 8 in the exhaust housing 5 of the extractor hood 1. This separating element 9 serves to separate one or more components of the cooking fumes 2 (. Fig. 1), in particular grease and / or oil, from the airflow 4. It can be removed upwards for cleaning via the air intake opening 6. To remove the separator element 9, a guide grid 21 for directing the airflow 4 through the air intake opening 6 and a cover element, which is movable on the guide grid 21 and influences the airflow direction, are removed from the air intake opening 6. The airflow 4 is guided in the exhaust housing 5 in a negative pressure section 10 from the air intake opening 6 via the separator element 9 to the fan 8. For this purpose, an intake chamber 15 connects laterally to the separator element 9 when installed. When installed, the separator element 9 connects to the air intake opening 6 in the direction of the airflow 4. The shape of the separating element 9 can differ from the rectangular design shown here and may, for example, be round or hexagonal or rotationally symmetrical.The intake chamber 15 of the negative pressure section 10, arranged laterally to the separating element 9, directs the airflow 4 from the separating element 9 to the fan 8. From the fan 8, the airflow 4 is guided via a positive pressure section 11 to the air outlet and blown out of the exhaust housing 5. Within the positive pressure section 11 of the exhaust housing 5, a filter element 12 is arranged in the airflow 4, serving to reduce odors. This filter element 12 can be made of activated carbon, which binds the odor molecules from the cooking fumes 2. Advantageously, this filter element 12 can be easily removed from the exhaust housing 5 via the negative pressure section 10 through the air intake opening 6. According to the invention, the filter element 12 is designed with a partition 13 for this purpose, which can be removed from the exhaust housing 5 together with the filter element 12. With filter element 12 installed, as in . Fig. As shown in Figure 10, the partition 13 on the filter element 12 closes an access opening 14 connecting the negative pressure section 10 and the positive pressure section 11. When the separator element 9 is removed via the air intake opening 6, the partition 13 can be opened to the access opening 14, which provides access to the filter element 12 for its removal through the air intake opening 6. Thus, no additional external opening is required in the extractor housing 5 of the extractor hood 1 or in the cooktop 3 of the combination appliance 18. The air intake opening 6 in the cooktop 3 is also easily accessible in the standard installation state of the combination appliance 18 in a (not shown) kitchen cabinet. Cleaning the separator element 9 provides a simple opportunity to also replace the filter element 12. The partition 13, which can be removed together with the filter element 12, makes the filter element 12 particularly easy to access for this purpose.Thus, the filter element 12 itself forms a partition 13 that closes the access opening 14 when the filter element 12, as in . Fig. 11 can be seen, into which the exhaust housing 5 is inserted. By removing the separating element 9 via the air intake opening 6, the partition 13 in front of the access opening 14 becomes accessible in order to remove the filter element 12 together with the partition 13 via the air intake opening 6. In the Fig. 10 and Fig. In the embodiment shown in Figure 11, the removable filter element 12 is arranged laterally to the side of the separating element 9, with the partition 13 forming a side wall of the filter element 12. Furthermore, the access opening 14 extends laterally adjacent to the negative pressure section 10 below the air intake opening 6. In the illustration according to Fig.Figure 10 shows that the fan 8, used to generate the airflow 4, preferably has a rotational axis tilted relative to the vertical. This allows for a particularly space-saving and efficient intake of the airflow 4 from the intake chamber 15. The filter element 12 can be removed from the positive pressure section 11 through the negative pressure section 10 at the air intake opening 6 in the exhaust housing 5 via the access opening 14. For this purpose, the filter element 12 must be detached from the filter seat 27 in the positive pressure section 11. The filter element 12 can then be removed through the access opening 14 via the negative pressure section 10. The inserted separator element 9 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 positive pressure section 11, with the channel section 17 running laterally past the separator element 9.
