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. Below the housing, a fan housing for two or more radial fans is arranged to suck the air from an underlying Kochdunstansaugkammer vertically upwards.

This embodiment has the disadvantage that the radial fans in the arrangement in order to provide the required suction power must have a large diameter. As a result, with a given dimension of the

Combination device in the height direction and / or width direction of the space below the hob, in which other components of the extractor device or the hob can be added or in which the sucked air can flow minimized.

It is therefore an object of the invention to provide a solution which at least reduces this disadvantage.

The object is achieved by a combination device which comprises a hob with at least one cooking module and a fume extraction device which is at least partially below the at least one cooking module and which has at least one fan with at least one suction opening, and at least one air inlet opening for the fume extractor is arranged in the hob. The Combination device is characterized in that the at least one fan is arranged in the combination device that the at least one suction opening of the fan is inclined to the plane of the hob. Directional information, such as above and below, as well as front and rear, unless otherwise stated, refers to the combination device and its components in an installed condition in which the hob and in particular the at least one cooking module are horizontal. The front side refers to the side facing the user. The back is the side that is usually facing a 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 at least one air inlet opening for the extractor device. The hob has at least one cooking module. In addition, the hob preferably includes a

Cover plate on which the cooking module or modules 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. However, it is also within the scope of the invention that the induction module has a plurality of induction coils, for example micro-induction coils. By means of such an induction module, for example, cooking zones can be freely defined on the surface of the induction module by placing food containers. The induction module is understood in particular to be a component which is intended to be a magnetic one while converting electrical energy

To generate alternating field, which serves in an at least partially ferromagnetic food container, such as a pot, eddy currents and / or

Cause magnetization effects, which are converted into heat. In the hob of the combination device according to the invention are preferably two

Cooking modules provided. But it can also be provided more, for example, four or six cooking modules. 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

Combined device delivered.

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 constitutes a radial fan, in particular a radial fan with forwardly curved blades, and the fan housing preferably adjusts

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, are sucked through the air through the fan in the blower housing can. The suction port is perpendicular to the axis of rotation of the fan of the fan in the fan housing.

The extractor device is at least partially disposed below the at least one cooking module. 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 by this

Recess formed. In the first case, the air inlet opening may be formed for example by a filter holder for filters of the extractor device, which in the

Recess is introduced. The cooking modules of the hob are arranged offset to the recess of the hob.

The combination device is characterized in that the at least one fan is arranged in the combination device that the at least one suction opening of the fan is inclined to the plane of the hob. The plane of the hob is defined by the cooking modules and preferably by the cooking plates cover the cover plate of the hob. In the cover plate, a recess is introduced, in which the air inlet opening for the extractor device is located or which represents the air inlet opening for the extractor device. As inclined to the plane of the hob, a suction port is designated which is not parallel to the plane of the hob.

By the at least one suction opening of the at least one fan is inclined to this plane, a number of advantages can be achieved. On the one hand, the intake opening can be the air flow, which via the air inlet opening in the combination device enter, be facing. As a result, a strong deflection of the air flow, which is required in the prior art, no longer required. In addition, the dimension of the fan is usually lower in the direction perpendicular to the suction port than in the radial direction of the fan. By an inclined arrangement of the blower, the dimension of the fan is no longer in the radial direction in the horizontal and in particular in the width direction of the combination device. This makes it possible to produce combination devices with smaller widths. For example, the combination device can be made with a width of 60cm. In addition, with the inclined orientation of the suction opening, it is also possible to use fans which have two opposite suction openings, without the height of the suction opening

To have to significantly increase the combination device.

According to a preferred embodiment, the at least one suction opening lies in the vertical. With this orientation, the advantages of the invention can be used particularly well. In particular, in the case of an intake opening facing the air inlet opening of the extractor device, a deflection of the air flow is required only by 90 °. In addition, the air can face at one of the air inlet opening

Suction opening are performed. Due to the lower deflection of the air flow, the requirement for the performance of the fan is lowered. Therefore, blowers with smaller radial dimensions can be used, reducing the height of the

Combination unit can be kept low. Furthermore, the dimension of the fan at a vertical orientation of the suction port (s) in the width direction of the combination device is small and it is at a given width of the

Combination device thus created a free space in the combination device. In this space or space other components of the extractor and / or the hob can be added. In addition, it is also possible by a vertical orientation of the suction port of the blower blower with two

Intake openings to use. Due to the smaller dimension of the blower with vertical intake openings, the space created thereby in the width direction can be used to guide the air to a suction opening of the blower facing away from the air inlet opening. Finally, with a vertical orientation of the suction port (s), the entry of contaminants into the fan is prevented.

Such contaminants may be, for example, fat particles deposited on a grease filter at the air inlet port, or other liquids or particles, which enter through the air inlet opening, for example, when overcooking food in the combination device.

According to one embodiment, the at least one fan has only one

Intake opening on. If several fans are provided, each of the fans has only one intake opening in each case. The embodiment of the blower with only one

Intake port is also referred to as unilaterally aspirating blower. These

Embodiment has the advantage that the fan housing is closed on the side opposite to the suction port. With this page, the fan can therefore be applied, for example, to a wall of a housing of the combination device or attached there. In particular, no distance to the wall of the housing is required and the width of the combination device can therefore be minimized or the empty space in the combination device, in which further components can be accommodated, can be increased.

According to a further embodiment, the at least one fan has two intake openings. If several fans are provided, preferably each of the fans has two intake openings. 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 blower or double-suction blower. By using a double-flow blower, the delivery volume of the blower can be increased even in the smaller dimension of the blower in the radial direction.

According to one embodiment, a suction opening of each fan is directed to one of the at least one air inlet opening for the extractor device. As directed to the air inlet opening is referred to a suction, which is the

Air inlet opening facing, that is, which can be achieved by the air entering through the air inlet opening, without having to flow past the radially outer periphery of the fan housing. By having one from each blower

Intake opening of the air inlet opening facing, on the one hand, a reliable extraction of air from above the hob even with a small interpretation of

Blowers are guaranteed. On the other hand, but also a targeted air flow take place to the intake by air guide elements. Furthermore, even with such an orientation of the suction port (s) due to the vertical position of the

Inlet opening (s) continue to prevent entry of contaminants in the fan housing.

Alternatively or additionally, an intake opening of each fan may face one of the sides of the combination device. As sides of the combination device, the ends thereof in the width direction are referred to. If the combination device comprises a housing, then the sides of the combination device are formed by side walls of the housing. By the suction port facing one side and in particular a side wall, the air flow through the side wall to the

Suction port passed. In addition, on the side of the combination device,

in particular on the side wall, at which the air flow is guided along

Insulating means, for example be provided in the form of an insulating mat, whereby the noise is damped. If a unilaterally aspirating blower is used, the noise is minimized in this embodiment.

In the combination device according to the invention, one or more air inlet openings of the extractor device can be provided. The

Air inlet opening or the air inlet openings are preferably each in a recess of the hob, in particular a cover plate of the hob. The placement of the at least one air inlet opening or the

Recess (s) in the hob can be made arbitrarily. Both the number and the position of the recess (s) and thus the air inlet opening (s) can be freely selected. For example, recesses can be introduced at the lateral edges of the hob or in the front or rear area.

According to a preferred embodiment, however, the air inlet opening is arranged in the middle of the width of the hob. Also in this embodiment is the

Air inlet opening disposed in a corresponding recess of the cover plate of the hob or is formed by the recess. Preferably, the

Air inlet opening and also the recess a rectangular, elongated shape and extending in the depth direction of the hob. This allows lateral to the

Air inlet opening cooking modules of the hob to be provided and thus a Reliable suction can be ensured during cooking on the cooking modules resulting streaks and vapors.

According to one embodiment, two blowers are arranged in the combination device. The two fans are in particular in a combination device in which the

Air inlet opening in the middle of the hob is arranged offset laterally outwards to the center of the combination device. Thus, each of the two fans is each below at least one cooking module. By two blowers are provided, the individual blowers can be made smaller. In addition, a uniform

Extraction of air from above the hob can be guaranteed. In addition, the space below the air inlet opening is free due to the lateral offset of the fan, so that in particular filter elements of the extractor device, for example, fat filter and / or odor filter can be provided. Preferably, in two laterally offset to the center of the combination device blowers with preferably vertical intake openings are the axes of the fan wheels in the

Width direction of the blower. Since the fan is a radial fan, with this orientation of the fan, the air outlet opening of the fan housing can be directed to the rear and thus the extracted air to the back of the

Combination device be routed. Preferably, therefore, in the back of the combination device, for example in the rear wall of a housing of the

Combination device provided an air outlet, which may be incorporated as an opening in the rear wall.

According to a further embodiment, only one fan is arranged in the combination device, which is offset to the center of the combination device to one side. In a combination device in which the air inlet opening is provided in the middle of the width of the hob, thus below the cooking modules or on one side of the recess of the hob, the fan may be provided, while below the cooking modules or on the other side of the recess of Hob is a space in which other components of the extractor device or the hob can be arranged. For example, the power electronics of the hob, in particular the cooking modules can be arranged there. According to one embodiment, the extractor device has at least one odor filter. As an odor filter, for example, an 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 extractor device has at least one odor filter, which in the region of the air inlet opening for the

Vapor extraction device is arranged. As a result, the advantage is achieved that the odor filter is easily accessible from above through the air inlet opening of the combination device. Since, in addition, with an arrangement of the odor filter in the region of the air inlet opening for the extractor device, the odor filter lies in the flow direction in front of the suction opening of the fan (s), this also causes a

Noise insulation realized. 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. The arrangement of the odor filter in the region of the air inlet opening is in the

Combinations device according to the invention possible because of the inclined and preferably vertical orientation of the suction port (s) of the blower or, room for the arrangement of the odor filter is given.

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

preferably on the back 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 have a high air resistance In order to filter out the odor particles in this is the arrangement of the

Odor filter in the flow direction after the or the blower advantageous. The passage of air through the grease filter, which is located in front of the blower, must generally be done at a high speed to filter the contaminants, which can be adjusted without the blower power being increased when the odor filter is placed after the blower. In the embodiment of the arrangement of the odor filter at the air outlet of the combination device through which no space required for the blower space is used, larger blower can be used, whereby on the one hand the noise compared to smaller

Blowers is reduced and on the other hand, a high delivery volume can be achieved.

According to one 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. Preferably, the cross section of the air duct member decreases from the grease filter to the suction port and the

Air duct element can therefore also be referred to as a funnel. In this case, the underside of the air duct element is preferably higher at the intake than at the grease filter. This can prevent the entry of contaminants, in particular of grease or liquids in the blower. The provision of an air duct element is possible in the inclined and in particular vertical orientation of the intake opening according to the invention. In particular, the air duct member is provided between the grease filter and the suction port of the blower facing the air inlet port. Therefore, one is

Air duct element especially in one embodiment of the

Combination device preferably, in which one or more fans suction on one side are provided, in which at least one suction opening in each case faces the air inlet opening. 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. Also, by providing the

Air duct element to be dispensed with a housing of 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 components 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.

According to one embodiment, the combination device has at least one carrier with the elements of the power electronics of at least one cooking module of the hob. The carrier, on or on which at least the elements of the power electronics of a cooking module are arranged, preferably represents a plate and can also be referred to as a circuit board. The carrier with the elements of the power electronics arranged thereon is also referred to below as a power electronics module

designated. The carrier (s) may be attached to the cooking module that powers them. According to a preferred embodiment, however, the at least one carrier is provided separately from the cooking module in the combination appliance.

Preferably, the elements of the power electronics for each on a 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. According to one embodiment, the at least one carrier is arranged perpendicular to the at least one cooking module in the combination device. This means that the at least one carrier lies in the vertical. By arranging the at least one carrier perpendicularly to the at least one cooking module, the carrier or carriers can be arranged in the combination appliance in areas which are not required for the fan (s) of the extractor device or for other components of the hob. In addition, a vertical orientation has the advantage that thereby access to the blower in the

Combination device from above or below can be ensured for maintenance purposes, which may not be possible with a parallel orientation of the carrier to the one or more cooking modules. Finally, it is also possible for a vertical arrangement of the carrier to use carriers of larger dimensions, without the

To obstruct the air inlet opening of the extractor device. For example, in a combination appliance having a cooktop with a width of 60cm,

Power electronics assemblies are used, which are also used in a hob without fume extractor, without blocking the recess in the hob and thus the air inlet opening of the extractor device. The at least one vertically arranged carrier may be arranged in the region of the front side of the combination device and in the width direction of the

Combination device extend. The front side of the combination device is the side from which the user operates the combination device. This page is usually the side of the combination device opposite with this on a

Room wall is applied. In particular, the front side is preferably the side of the

Combination device, which lies opposite 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. In the embodiment in which the at least one vertical support is arranged in the region of the front side of the combination device and extends in the width direction, the advantage can be used that an operating unit of the combination device is generally arranged in the region of the front side of the hob. Also the

Control electronics for the control unit is preferably in the area of the front arranged. Thus, at least the distance between the carrier or carriers and the operating electronics is minimized. In addition, the cooking modules are preferably arranged so that at least one cooking module is arranged in the vicinity of the front of the hob. Thereby, the distance between at least one carrier and at least one cooking module can be minimized. Finally, due to the arrangement of

Operating elements usually offset the recess in the hob usually to the front of the hob and thus the front of the combination device to the rear. Thus, in the vertical arrangement of the at least one carrier in the region of the front side of the combination device, an obstruction of the recess and the air inlet opening can be prevented.

As an alternative to the arrangement of the vertical support or supports in the region of the front side, the at least one support can also be arranged in the side region of the combination device and extend 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 through a wall of a housing of the

Combination device or in a combination device that has no housing, the side edge of the hob to be formed. This embodiment has the advantage that preferably the air inlet opening of the extractor device in a

Recess is arranged in the middle of the hob and the at least one carrier is therefore arranged spaced from the air inlet opening. Thus, a

Damage to the carrier and the elements of the power electronics located thereon can be prevented by contaminants that can enter through the air inlet opening. In addition, the access to the blower or a possibly provided odor filter is not impaired by the at least one carrier from above and from below. Finally, an operating unit, which is connected to a control electronics, be provided in the 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. Also, the electrical connection of the carrier or the arranged thereon elements of the power electronics with at least one cooking module is simplified by the orientation in the side areas and in the depth direction. In the case of a hob, several cooking modules are generally in the depth direction, in particular two cooking modules, arranged one behind the other. By extending the at least one carrier in the depth direction, the distance to the cooking modules is low and the electrical connection, in particular wiring is simplified. According to a further embodiment, the at least one carrier is to

at least one cooking module offset down and arranged below the at least one fan of the extractor device. Downwardly offset with respect to the at least one cooking module is a carrier which is spaced from the underside of the cooking module in the vertical direction. In this case, the at least one carrier can lie in plan view of the cooking module from above within the area and / or outside the surface of the cooking module. The at least one carrier is arranged in this embodiment below the at least one fan of the extractor device in the combination device. Again, the at least one carrier can be in plan view of the fan from above within the area and / or outside the surface of the fan.

In the embodiment in which at least one carrier is offset to the cooking module down and is arranged below the fan of the extractor device, on the one hand access to the fan and other components of the

Extractor device for maintenance easy from above. In addition, the area beneath the fan (s) in the combination appliance is not interrupted by the fan (s), so that the carrier may be of any size which need only be smaller than the dimensions of the hob in the horizontal directions. Furthermore, the at least one carrier is not located in the immediate inflow region, at which air enters the extractor device via the air inlet opening. Thus, the pollution of the held on the support elements of the power electronics is not to be feared. In addition, no breakthroughs or

Recesses in the carrier for the passage of parts of the extractor device required. The elements of the power electronics can therefore be arranged according to the electronic requirements on the carriers. Finally, a shielding of the at least one carrier from the air flow in the combination device in a simple manner possible. Preferably, the at least one carrier, which is arranged below the at least one fan, is parallel to the at least one

Cooking module. This means that the at least one carrier is preferably in the Horizontal lies. In this embodiment, the advantages mentioned can be used particularly well. In addition, the height of the combination device is not or only slightly increased by the horizontal orientation of the at least one carrier. Thus, the user is still the under the combination device normally provided storage space, such as a drawer available.

The combination device may comprise a housing of the combination device, in which the extractor device of the combination device, in particular the one or more fans, the grease filter, the odor filter, are added. 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 provided on the hob, in particular the cover plate cooking modules, are also in the housing of the combination device, but must not be attached to this.

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 filters 114 are held in the filter holder 140 in a direction inclined to the vertical. The filter holder 1 140 has a bottom, two side frame members, a front wall and a rear wall. At the top of the filter holder 1 140 is open and thus forms the upper edge of the air inlet opening 1 1 1 of the extractor device 1 first 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 is arranged. The blowers 110 in the embodiment shown constitute double-flow radial blowers. Therefore, in the blower housing 1100 there are two

Intake openings 1 101 provided perpendicular to the axis of rotation 1 103 of the

Fan wheel lie. The axes of rotation 1 103 of the blower 1 10 lie 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 the blower 1 10 is the filter holder 1 140 and thus the grease filter 1 14 faces. The other intake port 1 101, however, is the side of the

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

Air outlet opening 1 102 is followed by an air duct element 1 13, which extends from the air outlet opening 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 rear of the combination device 1, an air outlet 13 (see FIG. 5) 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 can for example be an activated carbon filter and preferably represents a mat or a molded body. The construction of the extractor device 1 1 in the flow direction after the air outlet opening 1 102 of the blower housing 1 100 is the same for both blowers 1 10 of the first embodiment of Figures 2 to 5. FIG. 5 is a schematic side view of the first embodiment of the invention

Combination device shown in Figure 2. In this view, it can be seen that carriers 103, 104 for the power electronics of the cooking modules are arranged in the lower region of the combination device 1, in particular in the lower region of the housing 12 of the combination device 1. Of the carriers 103, 104, only the right carrier 104 can be seen in the view according to FIG. The carriers 103 and 104 with the on it

provided elements of the power electronics are also referred to as power electronics 102. The cooking modules are included in the first embodiment of Figure 2 in a housing 106 of the hob 1 and are therefore not visible in the view of Figure 5. The hob housing 106 may also be referred to as a frame. The carriers 103, 104 are parallel to the hob 10 and extend across the width direction and depth direction of the cooking appliance 1. In the shown

Embodiment, the carrier 103, 104 are covered at the top by a cover plate 107. This represents in the illustrated embodiment, a flat sheet, which is offset to the bottom of the housing 12 upwards.

In the figure 3 is a schematic representation of the orientation of the blower 1 10 in the first embodiment of the combination device 1 of Figure 2 is shown. The blower 1 10 represent double-flow blower whose intake ports 1 101 lie in the vertical. The axes of rotation 1 103 of the fan lie in the horizontal. The air enters the combination device 1 via the recess 1000 and the air inlet opening 11 of the extractor device. First, the air passes through the grease filter 1 14 and then passes to the fat filter 1 14 facing intake port 1 101 of the respective

Blower 1 10 and to the fat filter 1 14 facing away from intake port 1 101 of the respective blower 1 10th

Through the use of double-flow blower 1 10, the delivery rate of the blower 1 10 is increased. Since in each case one of the suction openings 1 101 of the air inlet opening 1 1 1 of the extractor device 1 1 is turned away in the first embodiment, the perceptible by the air inlet opening 1 1 1 noise is further reduced. Finally, on the side walls of the housing 12 of the combination device 1 in addition a noise damping means, 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 illustration in FIGS. 2 to 5, the grease filters 14 can also extend further downwards. In the illustrated embodiment, the grease filters 1 14 terminate at a distance to the cover plate 107. In particular, the bottom of the

Filter holder 1 140, which can serve as a gutter, offset to the cover plate 107 upwards. As can be seen from FIG. 5, only part of the suction opening 101 of the blower 110 is in the region of the grease filter 14. If the grease filter 14 is configured with a greater height, the bottom of the filter holder 1 140 can be located on the Cover plate 107 rest or lie at a shorter distance to this.

In this way it can be ensured that the entire suction surface 1 101 of the blower 1 10 facing the grease filter 14 is covered by the grease filter 14.

FIGS. 6 to 9 show a second embodiment of the combination device 1. In the figure 7, the orientation of the blower 1 10 of the embodiment of the combination device 1 is shown schematically. The combination device 1 comprises two carriers 103, 104 in this embodiment. Elements of the power electronics of the cooking modules 101 of the hob 10 are arranged on the carriers 103, 104. The carrier 103, 104 are aligned in the second embodiment shown in Figure 6 to the cover plate 100 of the hob 10 and thus to the cooking modules 101 of the hob 10 in parallel. The carriers 103, 104 are located in the lower region of the combination device 1 and are arranged centrally in the width direction. The carriers 103, 104 are stacked one above the other. In the illustrated embodiment, the lower carrier 103 is disposed on the bottom of the housing 12 of the combination device 1. The second carrier 104 is arranged above the carrier 103 and is preferably congruent with the first carrier 103. The carriers 103, 104 are arranged centrally and thus lie below the recess 1000.

In addition, the combination device 1 according to the second embodiment, two fans 1 10 on. The blower 1 10 each have a suction port 1 101, that is, unilaterally sucking blower 1 10 represents. The axis of rotation 1 103 of the fan wheel of the blower 1 10 is in two blowers 1 10 in the horizontal. Thus, the intake ports 1 101 of the blower 1 10 are in the vertical. The fans 1 10 are arranged laterally offset from the centrally arranged carriers 103, 104. In particular, the fans 1 10 are in the vicinity of the side walls of the housing 12 or are attached thereto. Each fan 1 10 is aligned so that the closed side of the Blower housing, which is the suction port 1 101 opposite, the side wall of the housing 12 faces. The intake ports 1 101 are thus the center of the

Housing 12 facing. The fans 1 10 are arranged so that the

Suction openings 1 101 are only slightly covered by the upper carrier 104. It is also within the scope of the invention, the fan 1 10 to be arranged so that the

Suction openings 1 101 are above the upper support 104 and also above the held on the upper support 104 elements of the power electronics. For this purpose, however, the height of the combination device 1, that is, the height of the housing 12 must be increased or the size of the fan 1 10 can be reduced.

FIG. 6 shows a schematic perspective view of the second embodiment of the combination device 1. In this view, it can be seen that in the recess 1000 of the hob 10, as in the first embodiment, a filter holder 1 140 for the grease filter 1 14 is introduced. The grease filter 1 14 consists of two opposite plates or cassettes. The grease filter 1 14 may for example consist of expanded metal. The grease filter 1 14 is held in a filter holder 1 140, which in the illustrated

Embodiment consists of a front, a back and a channel-shaped bottom. The side surfaces of the filter holder 1 140 represent frames in which the grease filter, that is, in the illustrated embodiment in each case a part of the grease filter 1 14 is held. The grease filter 1 14 are in the inserted state in the vertical. But it is also within the scope of the invention that the grease filter 1 14 are arranged inclined to each other. In this case, the side surfaces of the filter holder 1 140 form a V-shape. Below the grease filter 14 and in particular the grease filter holder 140 are the carriers 103, 104. In the illustrated embodiment, the carriers 103, 104 are covered by a cover plate 107 upwards and to the sides. The cover plate 107 has for this purpose a downwardly open channel shape and may be attached to the bottom of the housing 12. The filter holder 1 140 extends so far from the recess 1000 down that it rests on the cover plate 107.

As is apparent from Figures 6 and 9, is to the air outlet opening 1 102 of the

Blower housing 1 100 each of the blower 1 10 each an air duct element 1 13 arranged. The air duct element 13 extends from the air outlet opening 1 102 funnel-shaped with increasing cross-section to the back of the combination device. 1 In the back of the housing 12 of the combination device 1, two air outlets 13 are introduced. Each of the air outlets 13 extends in the width direction from the side wall of the housing 12 to the filter holder 1 140. In the height direction, each air outlet 13 extends from the vicinity of the upper edge of the housing 12 to a height equal to the height of the two supports 103, 104

or the cover plate 107 corresponds. At each of the air outlets 13, an odor filter 1 15 is arranged. The air duct element 1 13 extends between the air outlet opening 1 102 of the blower housing 1 100 to the air outlet 13. The odor filter 1 15 may be introduced into the end of the air duct element 1 13 or the end of the air duct element 1 13 in

Flow direction downstream.

As is apparent from Figure 8, the space in the housing 12 of the combination device 1 is optimally used by the arrangement of the fan 1 10 with respect to the carrier 103, 104, the embodiment of the filter holder 1 140 and the embodiment of the air duct elements 1 13.

FIGS. 10 to 13 show a third embodiment of the invention

Combination device 1 shown. As is apparent from Figure 1 1, the arrangement of the blower 1 10 and the carrier 103, 104 is equal to the second embodiment shown in Figures 6 to 9. The statements made with respect to the second embodiment thus also apply to the third embodiment according to FIGS. 10 to 13. The third one

Embodiment differs only by the arrangement of the odor filter 1 15 and the width of the air outlets 13 of the second embodiment. As can be seen from Figures 10 and 12 are in the third embodiment, the odor filter 1 15 arranged laterally adjacent to the filter holder 1 140 and are thus in the flow direction after the grease filters 1 14. The air passing through the air inlet opening 1 102, through the top edge the filter holder 1 140 is formed, therefore, first flows through the grease filter 1 14 and the odor filter 1 15 before the air reaches the suction port 1 101 of the blower 1 10. The odor filter 15 preferably has a large thickness to

To be able to reliably filter off odors. In addition, the odor filter 1 15 extends over the entire depth of the filter holder 1 140 and thus ends in the region of the back of the housing 12. Due to the large thickness is at the third Embodiment, the width of the air outlets 13, which are formed in the back of the housing 12, smaller than in the second embodiment of Figures 6 to 9. Nevertheless, with this embodiment, a reliable suction and cleaning of the air can be ensured. In addition, due to the arrangement of the odor filter 1 15 in the flow direction after the grease filter 1 14 but before the intake port 1 101 of

Noise level, which passes through the recess 1000 of the hob 10 to the outside, reduced.

In the figure 14 is a fourth embodiment of the invention

Combination device 1 shown. This embodiment differs from the second embodiment by the arrangement of the carriers 103 and 104 and by additionally provided air duct elements 1 12. The blower 1 10 represent in the embodiment shown in Figure 14 unilaterally sucking blower, that is, each have only one suction port 1 10th on. The fans 110 are arranged in the side areas of the combination housing 12. The axes of rotation 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 14, the air duct elements 1 12 are arranged so that they each extend between the grease filter 1 14, in particular their clean air side, and the respective intake port 1 101 of the blower 1 10, wherein the cross-section of the suction port 1 101 funnel-shaped decreases. Also in the embodiment according to FIG. 14, 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 fourth embodiment in the front region of the combination device 1, are vertically aligned and extend in the

Width direction of the combination device 1.

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 one embodiment may be at another Embodiment can be realized without the other features of the embodiment must be transmitted.

According to the invention, the suction openings of the blower or in the vertical.

An advantage resulting from the arrangement of the suction openings according to the invention is that the dimensions of the components of the extractor device,

For example, the diameter of the fan at a given width of the

Combination unit to be selected larger than in a combination device in which the intake openings are horizontal.

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, the

Power electronics assemblies are installed in different positions, so that even power electronics modules can be used, which are also used in hobs without extractor device. Thus, the bearing holder can be simplified.
