Description

Combination unit with extractor and hob

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

Cooking usually produces fumes and vapors. There are

Vapor extraction devices known, by means of which the vapors and vapor can be sucked off and cleaned. For this purpose, for example, combination devices are known in which a fume extraction device is arranged below the hob. Such a combination device is described for example in DE 20 2013 005 303 U1. In this combination device, a housing for the heating or hob heating and control electronics is provided on the underside of the hob. Underneath the housing is a fan housing for two or more radial fans which draw in air from an underlying cooking vapor suction chamber.

This embodiment has the disadvantage that is reduced by the arrangement of the housing for the electronics of the space that is available below the hob and is necessary, for example, for the fan housing. Thus, the selectable size and possible orientation of the fan housing are limited

or the depth and / or width of the installation space must be increased, which is lost down the storage space for the user, such as a drawer or the combination device can not be performed in a width that is necessary for installation in standard kitchens, for example 60cm.

It is therefore an object of the invention to provide a solution that at least reduces these disadvantages.

The invention is based on the finding that this object can be achieved by a carrier for the power electronics of the hob is separated to the heating modules of the hob and arranged inclined in the combination device. The object is therefore achieved by a combination device having a hob with at least one cooking module and a fume extraction device which is at least partially disposed below the at least one cooking module and which has at least one fan with at least one suction port, and at least one

Air inlet opening for the extractor device, which is arranged in the hob. The combination device is characterized in that the

Combination device has at least one carrier with the elements of the power electronics at least one cooking module of the hob and the at least one carrier is arranged inclined to the at least one cooking module in the combination device.

The front side refers to the side facing the user. The back is the side, which is usually one

Facing mounting wall. In addition, the back of the combination device is preferably the side through which purified air is discharged from the combination device. The dimension in the direction between front and back is referred to as depth. The vertical dimension in the horizontal is called width. The dimension in the vertical is called height.

As a combination device, a household appliance is referred to, in which a hob and a fume extraction device are combined. In particular, as

Combination device denotes a household appliance that can be installed as a mounting unit in a kitchen. Preferably, the two components of the

Combination device, that is, the hob and the extractor device powered by a common power supply, for example, a common power cable. In addition, the control of the two components by a common

Control device take place, are combined in the control devices for the two components. For example, the two components can also be operated by a common operating unit.

The combination device comprises a hob, a fume extraction device and an air inlet opening for the extractor device. The hob has at least one Cooking module on. In addition, the hob preferably comprises a cover plate on which the cooking modules or the are arranged from below. The cover plate may for example consist of glass ceramic. Through each of the cooking modules at least one cooking zone is formed, that is, an area on which cooking material can be heated on the hob. The cooking module may be an electric heating module with a heating coil. However, the cooking module is preferably an induction module and is also referred to as an inductor. The induction module preferably comprises at least one induction coil. It is also within the scope of the invention that the induction module more

Induction coils, for example, has micro-induction coils. By such induction module, for example, cooking zones can be freely on the surface of the

Induction module can be defined by the placement of Gargutbehältern. When

Induction module is understood in particular a component which is intended to generate a magnetic alternating field by converting electrical energy, which serves in an at least partially ferromagnetic food container, such as a pot, eddy currents and / or Ummagnetisierungseffekte

which are converted into heat. In the hob of the

Combination device according to the invention preferably two cooking modules are provided. But it can also be provided more, for example, four or six cooking modules. Each cooking module forms at least one cooking zone.

The combination device further comprises a fume extraction device. When

Vapor extraction device is called a device by means of which air,

In particular contaminated air, for example in the form of fumes and vapor, can be sucked from the space above the hob down. Preferably, the air is cleaned in the extractor and as purified air

or discharged clean air from the extractor device and the combination device. The extractor device comprises at least one fan. In addition, the extractor device preferably comprises filters, in particular fat filters and odor filters. The extractor device therefore comprises according to the invention at least one fan. As a blower here is a unit consisting of a fan, in particular

Fan, and understood a fan housing surrounding the fan. The fan preferably provides a radial fan, in particular a radial fan with forward curved blades, and the fan housing is preferably one

Spiral housing, which can also be referred to as a screw housing.

The fan has at least one suction opening. In addition, the fan has an air outlet opening on the fan housing. The suction port is in the

Blower housing introduced, or formed by this, and represents the opening, can be sucked through the air through the fan in the blower housing. The suction port is perpendicular to the axis of rotation of the fan wheel. The extractor device is at least partially below the at least one

Cooking module arranged. In particular, at least the blower or blowers are arranged offset to the one or more cooking modules down.

The combination device further has at least one air inlet opening for the

Vapor extraction device on. The air inlet opening is the opening through which air from above the hob enters the combination device. The air inlet opening for the extractor device is also referred to below as the air inlet opening of the extractor device. The air inlet opening is arranged in the hob. In particular, the air inlet opening is arranged in a recess in the hob, in particular a recess in the cover plate of the hob. The air inlet opening may be in the recess of the hob or be formed by this. In the first case, the air inlet opening may be formed, for example, by a filter holder for filters of the extractor device, which is introduced into the recess. The cooking modules of the hob are arranged offset to the recess of the hob.

The combination device is characterized in that the combination device has at least one carrier with the elements of the power electronics of at least one cooking module of the hob and the at least one carrier is arranged inclined to the at least one cooking module in the combination device.

To operate the hob and in particular the cooking module is a

Power electronics required. The power electronics are used to provide the cooking module (s) with electrical energy. Here, the Power electronics transform the electrical energy, for example, with respect to the voltage shape or the current. The power electronics can for example

Filter components and control electronics include. The elements of the power electronics are, for example rectifier for rectifying the AC voltage of the

Domestic electricity network, inverters and switching devices, for example, for power management.

The elements of the power electronics of a cooking module can be arranged on or partially in the carrier. The carrier is preferably a plate and may also be referred to as a circuit board. The carrier with the elements of the power electronics is also referred to below as a power electronics module. The carrier is

arranged according to the invention inclined to the at least one cooking module of the hob in the combination device. When arranged inclined to the at least one cooking module, a carrier is referred to, which is not parallel to the surface of the cooking module and thus the surface of the hob, in particular the cover plate of the hob.

Preferably, the elements of the power electronics for each are on each carrier

Cooking module provided. However, it is also within the scope of the invention that the power electronics for several cooking modules of the hob is arranged on the carrier. The cooking modules are preferably connected via connecting cables, which can also be referred to as a coil cable, connected to the carrier or one of the carrier.

By arranging the at least one carrier inclined to the at least one cooking module, the carrier or carriers can be arranged in the combination device in areas which are not required for other components of the extractor device or the hob. In addition, an inclined orientation has the advantage that thereby the access to the other components in the combination device from above or from below can be ensured for maintenance purposes, which is not possible with a parallel orientation of the carrier to the one or more cooking modules. Finally, with an inclined arrangement of the carriers, it is also possible to use carriers of larger dimensions without obstructing the air inlet opening of the extractor device. For example, in a combination appliance having a cooktop with a width of 60 cm, power electronics assemblies can be used, even with a cooktop with a width of 60cm without fume extractor be used without obstructing the recess in the hob and thus the air inlet opening for the extractor device.

According to a preferred embodiment, the at least one carrier with the elements of the power electronics is arranged perpendicular to the at least one cooking module. If several carriers are provided, preferably all carriers are arranged perpendicular to the at least one cooking module. Since the hob and thus the cooking modules lie in the horizontal, is or lie the carrier in this embodiment in the vertical.

By this orientation of the carrier or with the elements of the power electronics, the advantages of the invention can be used particularly advantageously. In particular, a blocking of the air inlet opening for the extractor device by the one or more carriers is not to be feared. In addition, the space below the hob, in particular below the cooking modules, which is available for predetermined external dimensions of the combination device for the arrangement of components of the extractor device is maximized. Finally, in the vertical arrangement of the carrier or carriers, the distance between a carrier and the cooking module to be supplied by the elements of the power electronics of this carrier can be minimized. In particular, the upper edge of the carrier may be in close proximity to the corresponding one

Cooking module are brought, whereby the length of the connecting cable is minimized and thereby the electromagnetic compatibility risk is minimized

or the electromagnetic compatibility can be ensured. According to one embodiment, the at least one carrier is arranged in the region of the front side of the combination device and extends in the width direction of the

Combination device. As the front of the combination device in particular the side is designated, from which the user operates the combination device. This page is usually the side of the combination device with respect to this facing the room wall. In particular, the front side is preferably the side of the combination device which faces the side in which the air outlet of the

Kombinationsgerätes lies. If a plurality of carriers are provided, they are preferably located parallel to one another in the region of the front side of the combination device. As lying in the region of the front of the combination device, a carrier is referred to, which lies in a vertical projection on the hob from above near the front edge of the hob. If the combination device has a housing which is arranged below the hob, and in which at least the components of the extractor device are accommodated, a carrier can, for example, rest on the front wall of the housing or be offset to the rear at a small distance. In particular, the front area of the combination device is the distance which lies between the front end of a recess in the hob for the air inlet opening of the extractor device and the front edge of the hob.

The at least one carrier extends in the width direction. This means that the carrier or in a vertical orientation to the front of the combination device are parallel. The carriers can extend over the entire width of the combination device. At least the carriers may extend across the width of a housing of the combination device.

In the embodiment in which the at least one carrier is arranged in the region of the front side of the combination device and extends in the width direction, the carrier or carriers are preferably perpendicular to the cooking module (s). In this embodiment, the advantage can be used that the operating unit of

Combination device are usually arranged in the front of the hob. The control electronics for the operating unit is preferably arranged in the region of the front. Thus, at least the distance between the or

Carrier with the power electronics components and the control electronics minimized. In addition, the cooking modules are preferably arranged so that at least one

Cooking module in the area of the front of the hob ends. Thereby, the distance between at least one carrier and at least one cooking module can be minimized. Finally, due to the arrangement of control unit in the front region of the hob usually the recess in the hob to the front edge of the hob and thus the front of the combination device offset to the rear. Thus, the at least one carrier is covered in the vertical arrangement of the carrier in the front of the combination device from above through the hob, in particular the cover plate of the hob and locking the Recess and the air inlet opening through the carrier or carriers can be prevented.

According to a further embodiment, the at least one carrier is arranged in the side region of the combination device and extends in the depth direction of the

Combination device. When arranged in the side region, a carrier is referred to, which is arranged on the lateral edge of the combination device or in the vicinity of the lateral edge of the combination device. The lateral edge can by a wall of a housing of the combination device or a combination device that no

Housing, the lateral edge of the hob to be formed. If the carrier or the carriers are aligned vertically, they are parallel to the edge of the carrier

Combination device. The at least one carrier extends in the depth direction.

Preferably, the at least one carrier extends over the entire depth of the combination device or a housing of the combination device.

The lateral arrangement of the at least one carrier has the advantage that preferably the air inlet opening for the extractor device is arranged in a recess in the middle of the hob and the at least one carrier is therefore arranged at a distance from the air inlet opening. Thus, damage to the carrier and thereon elements of the power electronics by

Impurities that can enter through the air inlet opening can be prevented. In addition, especially in a vertical orientation of the or the side

arranged carrier access to the components of the combination device, such as the fan or an optionally provided odor filter, in the maintenance by the at least one carrier from above and below not impaired. Finally, an operating unit, which is connected to an operating electronics, be provided in the lateral edge region of the hob. Thus, the at least one carrier may be provided with its upper edge in the vicinity of the operating unit or at least the control electronics. This simplifies the electrical connection. The electrical connection of the power electronics of the carrier with at least one cooking module is simplified by the arrangement in the side areas and alignment in the depth direction. In the case of a hob, several cooking modules, in particular two cooking modules, can be arranged one behind the other in the depth direction. By extending the at least one carrier in the depth direction, the distance to the Cooking modules low and the electrical connection, especially wiring is simplified.

According to one embodiment, the combination device has two carriers and the two carriers are arranged next to one another. When arranged side by side, carriers are referred to, which extend in a same plane and abut each other with one edge or at least have only a small distance between the mutually facing edges. In this embodiment, the carriers are preferably arranged in the region of the front side of the combination device and extend in the width direction. Since the width direction of the combination device is usually greater than the depth of the combination device, carriers that extend in the width direction may have a larger dimension. In particular, in this embodiment, the two carriers can be mounted side by side, thereby covering the entire front of the combination device. This embodiment is advantageous, for example, if carriers are used which are designed for hobs which have no extractor device. These carriers may for example be designed for a hob with a width of 60cm and each have a width of 30cm. By arranging the carriers in the region of the front side of the combination device, these carriers can be arranged side by side without obstructing the space which is necessary for the extractor device.

According to a further embodiment, the combination device has two carriers and the two carriers are arranged offset from each other in parallel. Particularly preferably, the carriers are arranged so that the side of the one carrier on which the elements of the power electronics are arranged, the side of the second carrier on which the

Elements of the power electronics are arranged, is facing. As a result, the elements of the power electronics can be protected from contamination and mechanical damage by the carrier itself. In addition, a single cooling device can be sufficient for cooling the elements of both carriers. In the embodiment with two parallel carriers, the carriers may be located in a side region of the combination device or in the region of the front side of the combination device. When arranged in a side area, the entire combination device may have an asymmetrical structure. For example, only one fan may be provided in the combination device, which then lies in the side area of the combination device which is the side area, in the at least one carrier is located opposite. Preferably, however, the two carriers are in the region of the front side. This has the advantage that the width needed by the two carriers is reduced to the width of one of the carriers. Thus, even small widths of combination devices, such as 60cm can be realized.

According to one embodiment, the at least one carrier is held in a frame which is connected to the hob. As a frame in this case a holding structure is referred to, which allows attachment of the at least one carrier to the hob and holding the carrier in a predetermined position to each other in a plurality of carriers. In addition, on the frame, for example, a cooling for the elements of

Power electronics be attached. For example, the frame may surround the edges of each carrier and may additionally have mounting flanges for attachment to the hob, in particular a frame of the hob and / or for attachment of cooling.

According to a further embodiment, in addition to or as an alternative to a frame for holding the at least one carrier, a housing of the combination device may be provided, in which the at least one carrier is accommodated. In the housing of the combination device is also the extractor device of the

Combination device recorded. The housing may be a box-shaped housing that is open at least upwards. In addition, the housing preferably has an air outlet at the rear, for example in the form of an opening, via which air can escape from the combination device. An upwardly open housing is then closed by the hob upwards. In particular, the cover plate of the hob can close the housing upwards. The on the hob,

in particular the cover plate provided cooking modules, while also lying in the housing of the combination device, but need not be attached to this. By using a housing in which at least the extractor device and preferably also the cooking modules of the hob are accommodated, the assembly of the combination device can be simplified and damage to the individual components of the combination device can be prevented. The

Combination device is preferably introduced into a mounting opening of a worktop of a kitchen cabinet, in particular a base cabinet. Here is the Combination device introduced from above into the mounting hole. The carrier or the carriers can be held in the housing by, for example, corresponding holding elements are provided at the bottom of the housing into which the carrier or carriers can be inserted. However, other types of arrangement of the at least one carrier in the housing are also possible. For example, the carrier or carriers may be attached to the hob. Here, the housing serves only as protection against mechanical damage.

According to one embodiment, the combination device has at least one

Operating unit with an operating electronics, which is a separate component to the at least one carrier and is preferably arranged on the underside of a cover plate of the hob. In this embodiment, by the inclined

Alignment of the at least one carrier, the distance between this and the control electronics are kept low. The control electronics is usually connected to controls and display elements of the control unit, by means of which the user of the combination device on the hob can operate both the hob and the extractor device. From the control electronics is a

Transmission to the power electronics, which in turn controls the cooking module (s). By the control electronics represents a separate component, it can be arranged at a suitable location, that is near the controls of the control unit of the combination device, on the underside of the cover plate of the hob and are connected to the elements of the power electronics on the at least one carrier. However, it is also possible at least a part of

Control electronics, that is, to arrange elements of the control electronics on the support of the elements of the power electronics.

According to a preferred embodiment, the air inlet opening for the

Vapor extraction device arranged in the middle of the width of the hob. In particular, the air inlet opening is arranged in a corresponding recess of the cover plate of the hob. Preferably, the air inlet opening and also the

Recess a rectangular, elongated shape and extends in the depth direction of the hob. This can be provided laterally to the air inlet opening cooking modules of the hob and thus a reliable suction of cooking and cooking on the cooking modules resulting steam and vapor can be ensured. Through the middle Arrangement of the air inlet opening, the distance between the air inlet opening and the at least one carrier in an arrangement in the side regions of the

Combination unit can be maximized. This can prevent that

Contaminants passing through the air inlet opening into the interior of the

Get Kombinationsgerätes, reaches the carriers. In an arrangement of

Operating unit of the combination device in front of the air inlet opening and in particular in front of the recess in the cover plate, in the region of the front of the

Combination device or the carrier may be arranged, since this area is located in front of the recess and the carrier are thus covered up through the cover plate.

The extractor device has at least one fan. Each of the fans may in this case have a suction opening. The suction port is perpendicular to the axis of rotation of the fan of the fan. This type of blower is also referred to as a single-suction fan.

According to a further embodiment, at least one fan is the

Extractor fan one fan with two suction holes. The suction openings are in this case preferably along the axis of rotation of the fan offset from each other on opposite sides of the fan housing. The blower with two

Intake ports has only one fan and is also referred to as a double-flow fan or double-suction fan. By using a

double-flow blower can even with smaller design of the blower

Delivery volume of the fan can be increased. Due to the inclined and preferably vertical orientation of the carrier or the power electronics, the carrier or carriers in the combination device can also be arranged in a double-flow fan so that they do not hinder the flow of air to the suction openings of the fan. The suction can be in the vertical or in the horizontal direction. According to a preferred embodiment, the extractor device comprises two blowers, whose at least one suction opening is arranged vertically. This means that the axis of the fan is horizontal. This orientation of the suction opening (s) may allow contaminants to enter the suction opening (s). be prevented. The blowers with vertical intake, can be blowers with a suction or double-flow blower.

Preferably, with the use of two double-flow blowers or the carrier of the power electronics in the front of the combination device arranged and the fans are aligned so that a suction port of a first blower is facing a suction port of the second blower. Above the distance of these two intake ports of the two fans is then the

Air inlet opening arranged for the extractor device. The width of the

Air inlet opening is preferably smaller than the distance between the two fans, that is, between the suction openings facing each other. The

Air outlet opening of the blower housing is directed to the rear.

According to an alternative embodiment, the extractor device comprises two fans, whose at least one suction opening is arranged horizontally. Also in this embodiment, the blower can represent one-sided suction fan with a suction or double-flow blower. In the horizontally arranged intake, the axis of the fan is in the vertical. Such an orientation has the advantage that the height of the combination device can be kept low. Since the at least one support for the power electronics is inclined to the at least one cooking module and preferably arranged vertically in the combination device, this does not increase the height of the combination device, which in a horizontal arrangement of the carrier or in the horizontal above or below the fan the case would be.

According to a further embodiment, the extractor device has two fans and the two fans differ with regard to the orientation and / or number of the suction openings. For example, one fan may be a double-flow fan and the other fan may be a single-sided fan. In addition, or alternatively, it is possible that, for example, a fan is arranged so that its suction opening (s) lie in the horizontal and the further fan is arranged so that its suction opening (s) lie in the vertical. This asymmetric

Design and / or arrangement can be realized in the combination device according to the invention, since the available space below the hob due to the inclined and preferably vertical arrangement of the carrier of the power electronics is large.

According to a preferred embodiment, the extractor device

at least one odor filter on. As an odor filter, for example, a

Activated carbon filter can be used. The odor filter may be in the form of a mat, plate or shaped article. According to one embodiment, the odor filter is arranged in the region of the air inlet opening for the extractor device. As a result, the advantage is achieved that the odor filter through the air inlet opening is easily accessible from above. In addition, with an arrangement of the odor filter in the region of the air inlet opening for the extractor device of the odor filter in

Flow direction in front of the suction port of the blower or is realized by this also a noise insulation. The odor filter can be one or more parts. According to one embodiment, the odor filter may, for example, be arranged parallel to a grease filter which lies at least partially in the air inlet opening and preferably extends downwards from the latter. The grease filter can in this case run in the vertical or inclined to the vertical arranged in the combination device. Since the at least one carrier is inclined to the at least one cooking module and

is preferably arranged vertically, the available space under the hob space is large even with small size of the combination device, for example, a small width of 60cm and an arrangement of a thick odor filter in the air inlet opening is therefore possible.

According to a further embodiment, the extractor device has at least one odor filter, which is arranged on an air outlet of the combination device on the rear side of the combination device. The air outlet of the

Kombinationsgerätes may lie in the air outlet opening of the housing of the blower. Preferably, however, the air outlet of the combination device is formed by one end of an air duct element, which adjoins the air outlet opening of the housing of the blower and extends to the rear of the combination device. If the combination device has a housing in which at least the extractor device is received, a corresponding opening for the air outlet is introduced into the housing. The odor filter can at this

Embodiment be designed particularly large. The removal of the odor filter by the user takes place in this embodiment from below. The odor filter is arranged vertically. Since the odor filter must have a high air resistance in order to filter out the odor particles in this, the arrangement of the odor filter in the direction of flow after the blower (s) is advantageous. The passage of air through the grease filter, which is located in front of the blower, must be used to filter the

Impurities usually occur at a high speed, which at

Arrangement of the odor filter after the blower without increased performance of the

Blower can be adjusted. In that the at least one carrier is inclined to the at least one cooking module and preferably arranged vertically, and in the embodiment of the arrangement of the odor filter at the air outlet of the

Combination device is also used by this no required for the fan space, larger blower can be used, whereby on the one hand, the noise is reduced compared to smaller fans and on the other hand, a high performance can be achieved.

According to a further embodiment, the extractor device comprises at least one grease filter and between the clean air side of the grease filter and the suction port of the at least one fan, an air duct element is arranged. The

Air duct channel element preferably has a size at the end facing the grease filter, which corresponds to the area of the grease filter. At the opposite end, the air duct member has a size corresponding to the size of the

Suction opening of the blower corresponds. The cross section of the

Air duct element preferably decreases from the grease filter to the fan and thus has a funnel shape. By the or the air duct elements, the targeted air flow can be ensured in the combination device.

In particular, turbulences in a housing of the combination device, which could occur without the air duct element, can be prevented. In addition, in the case of an air duct element whose deepest point is in the region of the grease filter, impurities can be prevented from entering the blower. Also can be dispensed with by the provision of the air duct element on a housing of the combination device. Since the at least one carrier for the power electronics is also inclined to the at least one cooking module in the combination device and preferably oriented vertically, the at least one carrier can easily in a region of the combination device, for example on the front or in the area Are arranged sides of the combination device, in which an air duct between the grease filter and the fan is not required.

In Figures 3 and 4, the arrangement of the carrier 103, 104 according to the

Embodiment of Figure 1 shown in more detail. In particular, the carriers 103, 104 lie in the region of the front side of the combination device 1. In the embodiment of Figures 3 and 4, a housing 12 of the combination device 1 is provided under the hob 10. The carriers 103, 104 are arranged parallel to one another, wherein a carrier 103 is arranged on the inside of the front wall of the housing 12 and the second carrier 104 is arranged offset to the rear in the housing 12. The carriers 103, 104 are arranged such that the elements arranged on the two carriers 103, 104 for the power electronics face one another. Thus, the carrier 103 can be easily attached to the front wall of the housing 12 and the carrier 103 adjacent to the area in which the elements of the power electronics are to the other space in the housing 12, in particular the area under the

Recess 1000 off. In this embodiment, the upper edges of the carriers 103, 104 are in the area in front of the recess 1000. In this area, the operating unit 105 is preferably provided on the cover plate 100. Thus, the distance between the carriers 103, 104 and the operation unit 105 is small, and these can be easily electrically connected to the operation unit 105. Also in the embodiment according to FIGS. 3 and 4, the power electronics for the cooking modules (not visible) arranged on one side of the recess 1000 can be provided on a carrier 103 or 104, and the power electronics for the other carrier 104, 103 or the cooking modules, which are arranged on the other side of the recess 1000 may be provided.

In the second case is the Width of the individual carriers, for example, half the width of the combination device 1 or the housing 12 of the combination device. 1

In addition, it is also possible that the combination device 1 has no housing but the carriers are held by vertically extending frame in the front or in the side areas of the hob 10.

FIG. 5 is a schematic perspective view of an embodiment of the invention

Combination device 1 shown. For better visibility, the carriers of the elements of the power electronics are not shown here. The combination device 1 also has a hob 10 and a fume extraction device 1 1 in this embodiment. In addition, in this embodiment, a housing 12 of the combination device 1 below the hob 10 is arranged. In the hob 10, a recess 1000 is inserted in the cover plate 100. The recess 1000 is located in the middle of the width of the cover plate 100, has a rectangular shape and extends in the depth direction of the hob. 1 The front end of the recess 1000 is spaced from the front edge of the cover plate 100. Also to the rear edge of the cover plate 100, the recess 1000 terminates at a distance, which is less in the illustrated embodiment, as the distance between the front end of the recess 1000 and

Front edge of the cover plate 100. Side of the recess 1000 are in the illustrated embodiment, a cooking module 101 left and a cooking module 101 right. The cooking modules 101 rest against the cover plate 100 from below.

The extractor device 1 1 comprises in the illustrated embodiment, two blowers 1 10, two grease filters 1 14 with filter holder 1 140 and two odor filter 1 15. In addition, two air duct elements 1 13 are provided as part of the extractor device 1 1.

The filter holder 1 140, in which the grease filter 1 14, which may for example consist of expanded metal, are held, is introduced into the recess 1000 and extends from this vertically downwards. Thus, the fat filter 1 14 are in the vertical. However, it is also within the scope of the invention that the grease filter 1 14 in one

Direction, which is inclined to the vertical, are held in the filter holder 1 140. The filter holder 1 140 has a bottom, two side frame members, a front wall and a back wall on. Upwards, the filter holder 1 140 is open and thus forms the upper edge of the air inlet opening 1 1 1 for the extractor device 1 1, which is arranged in the recess 1000 of the cover plate 100. The two blowers 1 10 of the extractor device 1 1 are left and right adjacent to the filter holder 1 140 and thus each below the cooking modules 101 of the

Hob 10 10. The fan 1 10 represent in the embodiment shown doppelflutige radial fan. Therefore, in the fan housing 1 100 two suction ports 1 101 are provided which are perpendicular to the axis of rotation 1 103 of the fan. The axis of rotation of the fan wheels and thus the fan 1 10 is in each case in the horizontal and thus parallel to the hob 10 and in particular the cooking modules 101st The suction ports 1 101 of the blower 1 10 are in the vertical. A suction port 1 101 of each fan 1 10 is the filter holder 1 140 and thus the grease filter 1 14 faces. The other intake port 1 101, however, is one side of the

Combination device 1, in particular the side wall of the housing 12 facing. The Luftauslassoffnung 1 102 of the blower 1 10 is directed to the rear. To the

Luftauslassoffnung 1 102 joins an air duct element 1 13, which extends from the Luftauslassoffnung 1 102 to near the back of the combination device 1 and in particular the housing 12. The air duct element 1 13 has a funnel shape, that is, its cross-section increases over its length. At the back of the combination device 1, an air outlet 13 (see Figure 7) is provided. In the illustrated embodiment, this is formed by an opening in the rear wall of the housing 12. Between the back end of the

Air duct element 1 13 and the air outlet 13, an odor filter 1 15 is arranged. This may for example be an activated carbon filter and is preferably a mat or a molded body. The structure of the extractor device 1 1 in the flow direction after the Luftauslassoffnung 1 102 of the blower housing 1 100 is the same for both blowers 1 10 of the embodiment of FIG. FIG. 7 is a schematic side view of the embodiment of FIG

Combination device shown in Figure 5. In this view, it can be seen that in the region of the front of the combination device 1, in particular in the front region of the housing 12 of the combination device 1, two carriers 103, 104 for the

Power electronics of the cooking modules (not visible in Figure 7) are arranged. The Cooking modules are included in the embodiment of Figure 5 in a housing 106 of the hob 1 and are therefore not visible in the view of Figure 7. The carrier 103, 104 are perpendicular to the hob 10 and extend over the width direction of the cooking appliance 1. Since the recess 1000 in the cover plate 100 and thus the air inlet opening 1 1 1 of the extractor device 1 1 at a distance to the front of the cover plate 100th ends, the carriers 103, 104, which are arranged in the front region, are covered upwards by the cover plate 100. Thus it can be prevented that impurities, which may optionally enter the combination device 1 via the recess 1000, reach the carriers 103, 104.

In the figure 6 is a schematic representation of the orientation of the blower 1 10 in the embodiment of the combination device 1 of Figure 5 is shown. In particular, the air flow generated by the blower 1 10 in the combination device 1 is indicated here. The air enters via the recess 1000 and the air inlet opening 1 1 1 for the extractor device 1 1 in the combination device 1 a. First, the air passes through the grease filter 1 14 and then passes to the suction filter 11 facing the filter 1 1 101 of the respective blower 1 10 and to the fat filter 1 14 facing away

Intake port 1 101 of the respective blower 1 10th

Since the carriers 103, 104 are in the vertical with the elements of the power electronics of the cooking modules 101 in the front region of the combination device 1, the underlying area of the combination device 1, in particular the housing 12 for the components of the extractor device 1 1 is available. This large fan can be used 1 10, through which at low power, a large volume of air can be sucked. In this way, the cleaning of the air by passing through the grease filter 1 14 can be ensured in a simple manner. Even through the use of double-flow blower 1 10, the delivery rate of the fan 1 10 is further increased. On the other hand, the use of a larger blower 110 also reduces the noise which occurs when the air enters the blower 11. Since, in the embodiment according to FIG. 5, one of the intake openings 1 101 of the air inlet opening 1 1 1 for the extractor device 1 1 also faces away from each, the one which can be perceived by the air inlet opening 11 1 is

Noise development further reduced. Finally, on the side walls of the Housing 12 of the combination device 1 in addition a noise damping means (not shown), for example be mounted in the form of a plate without affecting the flow of air in the combination device 1. In a departure from the arrangement of the carriers 103, 104 in the front region of the combination device 1 shown in FIGS. 5 to 7, it is also possible to arrange the carriers 103, 104 on the opposite sides of the combination device 1. Here, the carrier 103, 104 must either be arranged so that their side, on which the elements of the power electronics are provided, the fan 1 10 are turned away or it must be provided an additional fender. Since this reduces the space available for the blowers and therefore only smaller blowers can be used, this embodiment is possible but not preferred.

FIGS. 8 and 9 show a schematic view of a further, second embodiment of the combination device 1 according to the invention. The carriers (not shown) are arranged in the region of the front side of the combination device, as shown in FIGS. 3 and 4. However, it is also possible to arrange the carriers 103, 104 in the side regions of the combination device 1, as shown in FIG. The second embodiment of Figure 8 differs from the first embodiment shown in Figure 5 by the blower 1 10. In the embodiment of Figure 8, two blowers 1 10 are provided, each having only one suction port 1 101. The axis of rotation 1 103 of the blower 1 10 is in this case in the vertical, that is perpendicular to the cooking modules 101. The suction ports 1 101 are therefore in the horizontal and thus parallel to the cooking modules 101. The blower 1 10 are on the bottom of the housing 12th arranged the combination device 1 and the suction ports 1 101 point upward. The blower 1 10 are arranged offset to the air inlet opening 1 1 1 and thus the recess 1000 in the cover plate 100 of the hob 10 to the sides and are thus below the cooking modules 101st In the embodiment shown in Figure 8, the blowers 110 each extend to the side wall of the housing 12. This large width is possible because the supports 103, 104 of the

Power electronics in the front of the combination device 1 are arranged. The air flow which is generated in the combination device 1 of the embodiment according to FIG. 8 is indicated schematically in FIG. The air is through the

Air inlet opening 1 1 1 of the extractor device 1 1 sucked in and passes through the grease filter 1 14 before it enters the corresponding intake port 1 101 of the blower.

FIG. 10 shows a schematic plan view of a further third embodiment of the extractor device 1 1 of the combination device 1. These

Embodiment differs from the embodiment shown in Figure 5 by the blower 1 10 and additionally provided by air duct elements 1 12. The blower 1 10 represent in the embodiment shown in Figure 10 unilaterally sucking blower, that is, each have only one suction port 1 10 on , The blowers 110 are arranged in the side regions of the combination housing 12. The axes of rotation 1 103 of the blower 1 10 are in the horizontal and the intake ports 1 10 so that in the vertical. As is apparent from Figure 10, air duct elements 1 12 are arranged so that they each extend between the grease filter 1 14 and the respective intake port 1 101 of the blower 1 10, wherein the cross-section decreases in a funnel shape to the intake port 1 101. Also in the embodiment according to FIG. 10, an air guide channel element 1 13 is arranged at the air outlet opening 1 102 of the respective blower housing 1 100, which extends to the rear side of the blower housing 1

Combination unit 1 extends and at the rear end of each one

Odor filter 1 15 is arranged. The carriers 103, 104 of the elements of

Power electronics are in the front region of the combination device 1, are vertically aligned and extend in the width direction of the combination device. 1 The air flow which is produced in the combination device 1 of the embodiment according to FIG. 10 is schematically indicated in FIG. 11. The air is through the

Air intake opening 1 1 1 of the extractor device 1 1 sucked in and passes through the grease filter 1 14 before it enters the corresponding intake port 1 101 of the blower 1 10.

FIGS. 12 to 14 show a further fourth embodiment of the combination device 1 according to the invention. This embodiment differs from the embodiment shown in FIG. 10 in that in this case the odor filters 15 are arranged adjacent to the grease filter 14 and no air duct element 12 is provided. In the embodiment according to FIG. 12, the odor filters 1 15 are arranged adjacent to the two devices of the filter holder 1 140, in which the fat filters 14 are vertically aligned, in the combination device 1. The filter holder 1 140 is inserted into the recess 1000 and extends downwardly therefrom. In particular, the grease filters 1 14 are in the illustrated embodiment vertically in a filter holder 1 140 on opposite sides of the filter holder 1 140. As a result, the two fat filter 1 14 form the side walls. The walls at the front, back and bottom of the filter holder 1 14 are impermeable to air. The grease filters 1 14 represent in particular plates or mats, which can be inserted in the frame of the filter holder 1 140. The fans 1 10 are aligned in the embodiment shown so that their intake ports 1 101 each faces the grease filter 1 14. In the embodiment shown, the

Spiral shape of the blower housing 1 100 in the two blowers opposite. Thus, in a blower 1 10, the air outlet opening 1 102 of the blower housing 1 100 above and at the other fan below. The different positions of the air outlet openings 1 102 are through the air duct elements 1 12th

balanced, so that the air outlet 13 of the combination device 1 for both fans 1 10 are at the same height.

Also in the embodiment according to FIGS. 12 to 14, the carriers 103, 104 for the elements of the power electronics are located in the vertical direction and are offset parallel to one another. In the view of Figures 13 and 14, the cooling 1021 is also shown for the elements of the power electronics. This is in the illustrated embodiment by

Cooling ribs 1022 are formed, which protrude at least partially into the intermediate space between the carriers 103, 104 in the lower region of the carriers 103, 104. There is also a

Cooling fan 1023 is provided, which further cools the elements of the electronics.

With the present invention, it is possible to develop a compact system with reliable filtering of the air. The present invention is not limited to the illustrated embodiments. Rather, individual features of an embodiment can be realized in another embodiment, without the further features of

Embodiment must be transmitted with. According to the invention are the carrier with the elements of the power electronics to the cooking modules inclined in the combination device. Preferably, the carriers are in the vertical. In this case, the carriers can be arranged on the front side of the combination device or on one or both sides of the combination device.

An advantage that can be achieved by the inventive arrangement of the carrier is the larger space available below the hob. In this room, the components of the extractor device can be aligned properly. In particular, the blower in different configurations or

Alignments are used. In addition, it is also possible to use two large blowers and large filter elements, in particular odor filter elements. Another advantage is the ease of access to the fans during maintenance, as the supports in their inclined orientation, especially vertical orientation, do not obstruct fan access from above. Also, other parts of the combination device including the carrier with the elements of the power electronics are easily accessible in the inventive alignment of the carrier for maintenance purposes. Also the

Electromagnetic compatibility is given by the continued proximity to at least one cooking module. The combination device can be designed with or without housing for the combination device, since the carrier in the inclined and

in particular vertical orientation can be easily attached to the hob, such as a frame of the hob can be attached.

Another advantage of the present invention is that a low

Noise development can be achieved because an arrangement of the odor filter is also possible in the area of the grease filter due to the large available space. The combination device can be made in different widths, for example, 60cm, 80cm and 90 cm. In this case, preferably

Standard components are used, for example, carriers with power electronics, which are designed for hob without extractor device. ßezugszeichen
