Description

The present invention relates to a combination appliance with a hob and extractor hood.

In kitchens, it is known to use so-called trough fans instead of extractor hoods, which are arranged above a hob, for example on the room wall or ceiling, in order to extract the vapors and vapors that arise during cooking. In the DE 10 2013 007 722 A1 such a downdraft ventilation is described, for example. Here, a cooking steam inlet opening located on the hob level is connected to a vacuum source via an exhaust air duct system. The downdraft ventilation is provided as a separate device between two cooktops or next to a cooktop. A disadvantage of this downdraft ventilation is the large amount of space that is required due to the exhaust duct system to be provided. In addition, the distance between the inlet opening and the negative pressure source is also large here, so that increased demands are placed on the negative pressure source, which in particular can represent a suction fan.

Furthermore, from the WO 2012/146237 A1 known a hob with central extraction of cooking fumes downwards. In this hob, one or more cutouts are made in the area around the geometric centroid. Devices for extracting kitchen fumes are provided below the hob. The devices for extracting kitchen vapors are preferably radial fans that are attached to the underside of a hob housing and are sucked upwards via the air from cooking vapors suction chambers located below.

A disadvantage of this arrangement is that the demands on the radial fan to generate a sufficient negative pressure are increased, in particular since the flow of cooking vapors has to be deflected.

In the U.S. 4,562,827 A describes a downdraft worktop range. The stove has a modular hob that is offset downwards from the worktop is. Side panels are provided around the hob with ventilation slots for exhaust air. The side panels lie between the ends of the hob and the top of the oven frame. The ventilation slots extend over the entire depth of the cooker. The ventilation slots are spaced apart from the hob.

In the U.S. 2,674,991 A describes ventilation means for cooking stoves. Here, a space is provided below the hob, which forms a storage space below the hob. A pull-off device is placed in this storage space. The motor of the extraction device is attached to the floor of the storage space. A pipe of the extraction device is inserted into the hob. A fan, which is a radial fan, is provided in the extraction device. The air that is sucked in by this fan enters through the openings in the upper part of the pipe.

The US 2006/0150965 A1 concerns an exhaust and cooling system. With this system, gas or odors are simultaneously extracted and the lower part of a grill is cooled. An exhaust fan and a cooling fan are used for this.

In the JP H 04 240317 A1 a cooking table is described. In this case, an upwardly open box is used, which has suction openings at the upper ends of the side walls. The hob is at the bottom of the box.

In the DE 37 41 721 A1 describes a heating cooking device with a cooling device and a suction device for extracting oil vapors or the like that arise during cooking. The suction device, which in one embodiment comprises a fan, is arranged below the cooking insert 35.

The object of the present invention is therefore to create a combination device in which, with a simple structure of the combination device, vapors and vapors can be sucked off from the space above a hob in a simple and reliable manner.

According to the invention, the object is therefore achieved by a combination device that has a hob with at least one recess and an extractor device arranged below the hob for sucking air from the space above of the hob via the at least one recess, which is the suction opening of the combination device. The combination appliance is characterized in that the hob comprises a cover plate and at least one heating element, that the cover plate covers the at least one heating element from above, that the at least one recess is made in the cover plate, that the extractor device has a single fan with an air inlet opening , which is arranged in the combination device that the air inlet opening of the fan faces the hob and that the hob (10) and the extractor device (11) are connected to one another via a common device housing (14) for introduction into a worktop and the fan ( 110) of the extractor device (11) is attached to the floor (140) of the device housing (14).

The combination device according to the invention comprises a hob and an extractor device. In particular, these two components of the combination device are designed as a structural unit. This means that the two components of the combination device are directly or indirectly attached to one another and can be installed as a unit, for example in a worktop. The combination device thus represents an assembly unit, i.e. an assembled or preassembled unit, or a unit that can be preassembled.

According to the invention, the hob comprises at least one heating element and preferably a cover plate. The cover plate covers the at least one heating element from above. The size of the heating element or its effective radius determines the size of the cooking zone or hob in the hob on which pots or other cooking vessels can be placed for heating. The heating element can represent an induction module, for example. Alternatively, the heating element can also be an electronic heating element in the form of a heating coil. Finally, it is also possible for at least one of the heating elements of the hob to be a gas burner. In the last-mentioned embodiment, the cover plate does not cover the heating element, but has a passage opening for passage for the burner head at the location of the heating element.

According to the invention, the fume extractor device comprises a fan and, preferably, also an air duct for guiding the air out of the combination device after it exits the fan.

According to the invention, at least one recess is provided in the hob. The recess can preferably be made in the cover plate of the hob. However, it is also within the scope of the invention that the recess or the recesses is or are formed by the space between adjacent heating elements of the hob and no cover plate but, for example, only a frame for the heating elements is provided. It is also possible for the hob to have, in addition to the cover plate, a housing in which the heating elements are accommodated. In this embodiment, the at least one recess is preferably made in the top and bottom of the housing of the hob.

According to the invention, the extractor device is arranged below the hob. An extractor device in which at least a part of the fan of the extractor device is located further down than the lowest point of the hob is referred to as being arranged below the hob. In any case, the extractor device is arranged below the top of the hob. If the top of the hob, as preferred according to the invention, is formed by a cover plate, the extractor device is arranged below the cover plate. The fan of the extractor device can, for example, be arranged between two heating elements of the cooktop or be completely offset downwards relative to the heating elements.

Directional information, such as above and below, relate to the combination device in the assembled and installed state, that is to say in the state in which it is placed in a horizontal worktop, for example.

The air from the space above the hob and in particular fumes and vapors that arise during cooking are sucked out according to the invention via the at least one recess in the hob. The recess in the hob is the suction opening of the combination device. The opening through which air enters the interior of the combination device is referred to as the intake opening of the combination device. Since the recess of the hob, which is preferably in the plane of the top of the hob, in particular the cover plate of the hob, represents the suction opening, there is no need for further line elements, such as For example, to provide channels or pipes that extend upwards with respect to the hob. The structure of the combination device and its handling are thus simplified. In particular, pots or other cooking vessels can be moved essentially freely on the hob. However, according to the invention, it is possible for elements, such as a filter unit, for example, to be provided in the suction opening, which possibly protrude slightly beyond the top of the hob.

According to the invention, the extractor device of the combination device has only a single fan. The fan, which can also be referred to as a fan or suction fan, preferably comprises a fan housing which is designed, for example, as a spiral housing or worm housing. A fan wheel is accommodated in the fan housing and is driven by a motor likewise accommodated in the fan housing. The fan housing has an air inlet opening through which the sucked in air can reach the fan wheel. Furthermore, the fan housing has an air outlet opening, via which air can be discharged radially into a discharge duct or directly from the combination device. In the case of a fan that is a radial fan, the air inlet opening is preferably in the area of the axis of the fan wheel.

According to the invention, the fan is arranged in the combination device in such a way that the air inlet opening of the fan and in particular of the fan housing faces the hob. An air inlet opening is referred to as facing the hob, through which air can be sucked into the fan and thus the fan housing from above. In particular, an air inlet opening is referred to as facing the hob, which is located on top of the fan and thus the fan housing. The air inlet opening is preferably parallel to the hob and in particular to a cover plate of the hob. In this case, the air inlet opening is thus in the horizontal and is directed upwards. However, an air inlet opening inclined with respect to the horizontal on the upper side of the fan can also be viewed as facing the hob. However, the angle of inclination here is preferably less than 90 ° and more preferably less than 45 °. By providing a combination device according to the invention in which a single fan is used, the air inlet opening of which faces the hob, a number of advantages can be achieved. Since the air inlet opening faces the hob, on the one hand the suction of air via the recess (s) in the hob can be simplified. In particular, only a slight deflection of the air flow is required. Thus, the requirements on the performance of the fan are reduced. In addition, by aligning the fan with an air inlet opening facing upwards, the size of the fan can be selected independently of the size of the heating elements or the housing of the hob. The fan can be attached to the side of the fan housing that is opposite the air inlet opening. In contrast to the prior art, in which the fans are attached to the underside of the housing of the heating element with the side opposite the air inlet opening, a larger fan can thus also be used in the combination device according to the invention. The fan can for example be attached to the bottom of a device housing of the combination device, the area of which generally corresponds to the area of the hob. In addition, it is also possible according to the invention to attach the fan on the same side in which the air inlet opening is provided in an area around the air inlet opening on the hob, in particular on the underside of the hob and in particular an underside of a hob housing. In this embodiment too, since the air inlet opening of the fan faces the hob, that is, it is directed upwards, in particular in an embodiment in which the air inlet opening is below the at least one recess, the size of the fan can be selected to be large and the fan, for example, below two heating elements are attached, which are on opposite sides of the recess. A larger fan, which is possible in this way, can generate the desired air flow even at a lower speed and the noise generated by the fan is therefore also reduced. Since, in addition, only one fan is used, the development of noise can be further reduced compared with the prior art, in which several fans are used, and sufficient and reliable suction of air from the space above the hob can still be achieved. In addition, the construction of the combination device is simplified by using a single fan.

Since, according to the invention, the hob and the extractor device are still integrated in one device, assembly or installation is simplified. In particular, the hob and extractor device can be incorporated into a worktop or other surface as a unit and, if necessary, removed. Furthermore, by integrating the two components in a combination device, the required overall height is reduced, since the components of the components can be provided in the combination device in alignment with one another. The overall height of the combination device according to the invention can for example be 15 to 30 cm and preferably 20 cm. The combination device can thus be easily integrated into a kitchen. Finally, since according to the invention the recess in the hob forms the suction opening of the combination device, the space above the hob is free and therefore pots or pans, for example, can be moved without hitting a component of the extractor device, as occurs for example with filter elements that can be extended upwards.

According to one embodiment, the air inlet opening of the fan lies at least partially under at least one of the at least one recess in a plan view of the hob. This means that when the recess is projected vertically onto the fan below, the air inlet opening of the fan lies at least partially in the area of the recess. This alignment minimizes the flow path from the air sucked in via the recess to the air inlet opening and sufficient suction of air from the space above the hob can be ensured.

According to one embodiment, the entire air inlet opening lies in a vertical plan view of the recess under the recess, that is to say in the area of the recess.

If several recesses are provided in the hob, the fan can be located under one of the recesses in a vertical plan view, or else under several recesses. In the following, reference is essentially made to an embodiment with a recess in the hob. Unless otherwise stated, the statements made then also apply to an embodiment of the combination device with several cutouts.

According to a further embodiment, however, it is also possible for the air inlet opening of the fan to be located in a vertical projection of the recess onto the plane of the air inlet opening outside the area of at least one of the at least one recess. In this embodiment, the air inlet opening of the fan is particularly preferably located outside the area of all the cutouts in a vertical plan view, that is, it does not lie under any of the cutouts. In this way, the fan can be protected in a simple manner from objects falling in, and in particular liquids from entering, and the reliable functioning of the extractor device can thus be guaranteed. The inflow path that has to be covered by the air sucked in via the recess or recesses in such an embodiment is longer than in the embodiment in which the air inlet opening is in the recess in a vertical plan view, but the inventive orientation of the air inlet opening in In the direction of the hob, only a slight deflection of the flow is still required. The embodiment in which the air inlet opening is offset with respect to the recess (s) has the further advantage that the fan is not visible to the user of the combination device, at least in a vertical plan view. In addition, with the laterally offset arrangement of the fan relative to the recess or the recesses, the entire distance between the recess and the underside of the combination device is available for filters or other air guiding elements.

According to the invention, the hob and the extractor device can be fastened directly or indirectly to one another. In the case of direct attachment, for example the side of the fan of the extractor device in which the air inlet opening is provided can be attached to the hob, for example to the underside of a hob housing.

An indirect fastening of the hob and the extractor device is implemented according to the invention by means of a device housing. In this embodiment, the hob and the extractor device are accommodated in a common device housing. The device housing can in particular have a trough shape. At the top, the device housing is closed off by the hob and, if provided, in particular by the cover plate of the hob. In An air outlet is also incorporated into the device housing. The air outlet can for example be provided on the back of the device housing. Alternatively, however, it is also possible that the air outlet is made on one of the side walls of the device housing or is made in the bottom of the device housing. At least the extractor device of the combination device is preferably attached in the device housing. The hob can either be introduced into the device housing from above and, for example, rest with the cover plate on the upper edge of the walls of the device housing. Alternatively or additionally, however, the heating elements of the hob can also be attached or held, for example, to the inside of the device housing.

Since the hob and the extractor device are directly or indirectly connected to one another in the combination device, both the assembly and the assembly of the combination device are simplified. When assembling, if a device housing is provided, the relative position between the components of the extractor device and the hob is already predetermined. During assembly, in particular when it is introduced into a worktop, the components of the extractor device and hob or the directly attached extractor device and hob can be inserted into a worktop or other surface in one assembly step. If the cover plate is a separate component of the hob from the heating elements, it can optionally be placed subsequently.

According to a preferred embodiment, the hob and the extractor device of the combination device have a common electrical mains connection. This mains connection can be provided, for example, on the device housing and supply the electrical components of the extractor device and the hob with voltage. Furthermore, the components of the extractor device and the hob can also be controlled by a common control device. For example, the extractor device can be operated depending on the operating state of the hob.

According to the invention, the extractor device and the hob are accommodated in a common device housing and the fan The extractor hood is attached to the bottom of the device housing. In particular, the side of the fan housing which is opposite the air inlet opening is fastened to the floor of the device housing. This embodiment has the advantage that the fan can be held securely on the bottom of the device housing. In addition, the assembly of the combination device is further simplified in this embodiment. In particular, for example, the fan can be attached to the bottom of the device housing before the hob is introduced into the device housing. The floor is still freely accessible in this state and assembly is thus simplified.

According to one embodiment, at least one of the at least one recess extends over the center of the surface of the hob. In one embodiment, a single recess can be made in the hob. This can for example have a round cross section. Alternatively, however, in this embodiment the recess can also have a square, in particular rectangular, cross section, for example. In this case, the recess can be a square recess in the center of the surface of the hob. In this embodiment, however, the recess preferably extends over the depth of the hob, that is, it forms a wide slot which extends from the area of the front of the hob to the area of the rear of the hob. By providing a recess that extends over the center of the surface of the hob, an alignment of the recess to the cooking zone or zones of the hob can be ensured, in which vapors and fumes from cooking vessels on the cooking zone or zones of the hob can be reliably extracted. If, for example, four cooking zones are formed in the hob, two cooking zones can be located on the right and two cooking zones on the left of a cutout that is centrally made and extends over the depth of the hob. The depth of the hob is understood to mean the direction between the front of the hob and the rear in the assembled state.

According to one embodiment, the combination device comprises at least one cover for covering at least part of the at least one recess. The shape of the cover is adapted to the shape of the recess in the hob. In the case of a round recess, a round cover is usually used. At a rectangular recess in the hob, a rectangular cover is preferably used.

The cover can be detached from the combination device, in particular from the hob.

The size of the cover can correspond to the size of the recess. In this case, the entry of liquids and other impurities into the recess (s) is completely prevented by the cover in the state in which the range hood device is not in operation. Alternatively, however, it is also possible that the size of the cover is smaller than the size of the recess. In this embodiment, for example, in the case of an elongated square cross section of the recess, the length of the cover can correspond to the length of the recess, but the width of the cover can be less than the width of the recess. Depending on the positioning of the cover on the recess, either a single lateral gap can be formed through which air can enter the combination device. Alternatively, however, two lateral gaps can also be formed which extend over the length of the recess. The last-mentioned embodiment is particularly preferred in the case of a recess that extends over the center of the surface of the hob, since this enables targeted suction of left and right cooking zones. The embodiment in which only one gap is formed can be used, for example, in an embodiment in which recesses extend along the side edges of the hob in the depth direction. Here, the cover is positioned on the recess in such a way that the gap formed thereby lies on the side of the recess which adjoins or is adjacent to the cooking zones.

According to the invention, however, it is also possible for the cover to have dimensions that deviate in all surface directions from the dimensions of the recess to which it is to be applied. For example, a round cover can be used which has a smaller diameter than the diameter of a round recess on which it is to be applied. Even with a rectangular cover, both the width and the length of the cover can be smaller than the corresponding dimensions of the recess. As a result, a circumferential gap is formed around the cover, through which air can enter the recess. According to a preferred embodiment, a filter unit is provided between the fan of the extractor device and the hob. The filter unit lies in particular between the at least one recess in the hob and the air inlet opening of the fan. A unit that is detachably connected to the combination device is referred to as a filter unit. In particular, the filter unit is inserted into the recess or the filter units are inserted into the recesses. The filter unit can be held on the recess, preferably on the edge of the recess. The filter unit is practically suspended in the recess. According to the invention, the filter unit comprises at least one filter element. In addition, the filter unit preferably has at least one filter holder, by means of which the filter element can be held on the combination appliance, for example on the recess in the hob. The filter element can be a flat filter element, for example a filter plate or filter mat.

Alternatively or additionally, however, filter elements that describe a hollow body can also be used. For example, a round pipe section or a rectangular pipe section made of filter material can be used. Other shapes, such as two filter elements arranged inclined to one another, can also be used in the filter unit.

The filter material of the filter element can be expanded metal, braided metal or the like.

According to a preferred embodiment, the filter unit has a collection area for liquids. A collection area for liquids is an area in which liquids that are released from the filter element and / or get into the interior of the combination device in some other way can be at least partially collected. The collecting area therefore preferably has the shape of a trough or channel. The collecting area is particularly preferably formed on the filter holder. The filter element is held on the combination device, in particular on the recess in the hob, via the filter holder. By forming the collecting area on the filter holder, a number of advantages can be achieved. On the one hand, the filter unit is detachably introduced into the combination device. Thus, when the filter unit is removed, the collecting area can also be emptied and cleaned, for example to clean the filter element. In addition, when the collection area is provided in the filter holder and thus in the vicinity of the filter element, liquids and other contaminants can be reliably collected from the filter element itself.

The fan of the extractor device of the combination device according to the invention is preferably a radial fan.

In Figure 1 a first embodiment of a combination device 1 according to the invention is shown. The combination device 1 comprises a hob 10 and an extractor device 11. The hob 10 is arranged in the upper region of the combination device 1. In the embodiment shown, the hob 10 consists of a cover plate 103 and heating elements (not visible) arranged below the cover plate 103. The area of the cover plate 103 in which a heating element is arranged under the cover plate 103, that is to say, on which the food to be cooked can be heated, is also referred to as the cooking zone 102 or hotplate.

The combination device 1 comprises a device housing 14. In the embodiment shown, the hob 10 is placed on the device housing 14. In addition, a hob housing 105 is provided in the first embodiment, in which the heating elements 101 of the hob are accommodated and which has a base 1050. The hob housing 105 can be inserted into the appliance housing 14 or applied to it. An extractor device 11 is provided in the device housing 14. From the extractor device 11 is in Figure 1 only the fan 110 can be seen. The fan 110 is fastened to the device base 140 of the device housing 14.

How out Figure 1 results, a recess 104 is made in the center of the surface of the hob 10 and in particular in the cover plate 103. In Figure 1 is indicated schematically that in the underside of the hob 10, that is, in the bottom 1050 of the hob housing 105, another opening corresponding to the recess 104 is provided.

The fan 110 is at the in Figure 1 The embodiment shown is arranged centrally under the recess 104. In particular, the air inlet opening 115 of the fan housing 113 lies in a vertical plan view of the recess 104 in the surface of the recess 104.

As an alternative to the embodiment shown, in which the hob 10 and the extractor device 11 are accommodated in a device housing 14, according to the invention it is also possible to design the combination device 1 without the device housing 14. In such an embodiment, the upper side of the fan 110, that is to say the side in which the air inlet opening 115 is provided, can then be fastened to the underside of the hob housing 105 in the area that is outside the air inlet opening 115.

In Figure 2 a second embodiment of the combination device 1 according to the invention is shown.

The second embodiment of the combination device 1 also consists of a hob 10 and an extractor device 11. The combination device 1 is in a Worktop 2 introduced. In the embodiment shown, in contrast to the first embodiment, the hob 10 is partially accommodated in the device housing 14. In particular, in the second embodiment, the heating elements 101 of the hob 10 are introduced in the upper region of the device housing 14. In the lower area, as in the first embodiment, the fan 110 of the extractor device 11 is attached to the device base 140 of the device housing 14. The combination device 1 is closed at the top by a cover plate 103 of the hob 10. A hob housing 105, in particular a base 1050, is not provided in the second embodiment.

In an embodiment of the combination device 1 without a device housing 14, the fan can be attached to the cover plate 103 or a frame (not shown) of the hob.

A recess 104 is made in the cover plate 103 of the hob 10, which in the second embodiment is also in the center of the surface of the hob 10. The fan 110 is arranged centrally on the device base 140 and is thus centrally located under the recess 104. An air inlet opening 115 is formed in the top of the fan 110, in particular of the fan housing 113. An access protection grille (not shown) can be provided in the air inlet opening 115. A filter unit 12 is arranged between the recess 104 and the air inlet opening 115. In the embodiment shown, the filter unit 12 comprises a filter holder 121 and a filter element 120 held therein. In the embodiment shown, the filter holder 121 has a shape that tapers conically towards the air inlet opening 115. In the case of a round recess 104 in the cover plate 103, the filter holder 121 can for example have the shape of a truncated cone. The filter element 120 is arranged horizontally in the filter holder 121 in the illustrated embodiment. In the case of a frustoconical filter holder 121, the filter element 120 can therefore have a round cross section.

In the embodiment shown, the filter holder 121 covers the entire distance between the recess 104 in the cover plate 103 and the air inlet opening 115 of the fan 110. The filter unit 12 is provided detachably on the combination device 1, that is to say can be removed from it.

Although in the second embodiment the filter unit 12 was described as consisting of the filter holder 121 and the filter element 120, it is also possible according to the invention for the filter unit 12 to consist only of the filter element 120 and that as a filter holder 121 in FIG Figure 2 The component shown is firmly connected to the cover plate 103 of the hob 10 and is therefore not included in the detachable filter unit 12.

The function of the combination device 1 according to the first and second embodiment will now be described again.

In the fan 110, the fan wheel 112 is driven by a motor 111. As a result, air is sucked into the fan housing 113 via the air inlet opening 115 of the fan housing 113 facing upwards and thus facing the hob 10. The air is sucked into the combination device 1 from above the hob 10 through the recess 104 which forms the suction opening of the combination device 1. The air is directed to the air inlet opening 115 in a targeted manner through the filter holder 121 or a stationary component designed in accordance with the filter holder 121, which extends from the recess 104 to the air inlet opening 115. The sucked air flow L passes through the filter element 120. The air cleaned in this way is blown out radially via an air outlet opening (not shown) of the fan housing 113 and from there either indirectly via an outlet duct (not shown) or directly to an air outlet (not shown) of the Device housing 14. From there, the air can be released into the environment or into the room in which the combination device 1 is operated.

Since the recess 104 in the hob 10 represents the suction opening for the extractor device 11 of the combination device 1, no components protrude above the top of the combination device 1 and pots or pans that are used on the cooking zones 102 of the hob 10 can be moved freely will.

The recess 104 can be covered by a cover (not shown) at least for the duration in which the extractor device 11 is not operated.

In Figure 3 a third embodiment of the combination device 1 according to the invention is shown. This embodiment corresponds essentially to the first embodiment from FIG Figure 1 . However, in the third embodiment, in contrast to the first embodiment, the fan 110 of the extractor device 11 is arranged laterally offset from the recess 104 of the hob 10. The air inlet opening 115 of the fan housing 113 is thus in a vertical projection of the recess 104 on the plane of the air inlet opening 115 outside the recess 104.

Also in Figure 4 , in which a fourth embodiment of the combination device 1 is shown, the fan 110 is arranged laterally offset from the recess 104. In the embodiment shown, in contrast to the third embodiment, the hob 10 is partially accommodated in the device housing 14. In particular, in the fourth embodiment, the heating elements 101 of the hob 10 are introduced in the upper region of the appliance housing 14. In the lower area, as in the third embodiment, the fan 110 of the extractor device 11 is attached to the device base 140 of the device housing 14. The combination device 1 is closed at the top by a cover plate 103 of the hob 10. A hob housing 105, in particular a base 1050, is not provided in the fourth embodiment.

In the fourth embodiment, too, the recess 104 is introduced centrally in the cover plate 103, that is to say in the center of the surface of the hob 10. In the fourth embodiment, the fan 110 is shifted to one side in the device housing 14 to such an extent that in particular the air inlet opening 115 and, in the embodiment shown, also the fan housing 113 are not below the recess 104.

In the fourth embodiment, an air duct 15 is provided between the recess 104 and the fan 110. In the upper area, this serves as a filter holder 121. In the horizontal area, which lies under the recess 104, the air duct 15 also serves as a collecting area 122 for liquids. The air duct 15 ends at the air inlet opening 115 of the fan housing 113.

With the present invention, a combination device is thus created in which air can be sucked in, for example, via a recess provided in the center of the hob. The air can then pass through a filter and into one from above Fan housing are sucked in. The air can then be blown out laterally by the fan, for example, and guided out of the combination device in a duct. The fan can be installed directly under the recess. Protection against ingress of liquids can be created, for example, by a cover. Alternatively, the fan can also be positioned to the side of the recess. The fan is then no longer visible to the user. A filter element can be made larger / higher in this embodiment.
