Description

[0001] The present invention relates to a combination appliance with a range hood and a cooktop.

[0002] Cooking processes typically produce fumes and vapors. Extraction systems are known that can extract and clean these fumes and vapors. For example, combination appliances are known in which an extraction system is located below the cooktop.

[0003] German patent DE 10 2017 217 853 A1 describes a cooker hood for extracting cooking fumes downwards. The cooker hood comprises a fan unit for drawing in the cooking fumes, with a rotatable fan wheel, a fan motor for providing drive torque, and a detachable fan coupling for transmitting the drive torque to the fan wheel.

[0004] Another combination appliance is described, for example, in DE 20 2013 005 303 U1. In this combination appliance, a housing for the heating or cooktop heating and control electronics is provided on the underside of the cooktop. Below this housing is a fan housing for two or more radial fans, which draw air upwards from a cooking fume extraction chamber located below.

[0005] Furthermore, EP 3 136 004 A1 describes a combination appliance comprising a cooktop with at least one cover plate and at least one heating element, and a range hood arranged below the cooktop with a fan for extracting air from the space above the cooktop. The cooktop has at least two recesses. These at least two recesses are horizontally offset from the fan located below the cooktop, and the edges of the recesses, when projected vertically onto the fan below, lie near or partially on the edge of the fan's air inlet opening.

[0006] EP 3 457 033 A1 describes a cooker hood for extracting exhaust air generated on a cooktop in a vertical direction below a cooktop plane, wherein the cooker hood has an air conveying duct whose inlet opening is arranged in a recess of a cooktop, wherein the air conveying duct is arranged vertically to a plane defined by the inlet opening.

[0007] These designs have the disadvantage that the arrangement of the housing for the electronics reduces the installation space available below the hob, which is necessary, for example, for the fan and filters.

[0008] The object of the present invention is therefore to create a combination device that has a compact design and yet exhibits high efficiency in the extraction and filtration of fumes and vapors.

[0009] The problem is therefore solved by a combination device according to claim 1.

[0010] Directional terms, such as top and bottom, as well as front and back, refer, unless otherwise specified, to the combination appliance and its components in an installed state, with the cooktop and, in particular, the at least one cooking module positioned horizontally. The front is the side facing the user. The back is the side that typically faces a mounting wall. Furthermore, the back of the combination appliance is preferably the side through which purified air is discharged. The dimension in the direction between the front and back is referred to as depth. The horizontal dimension perpendicular to this is referred to as width. The vertical dimension is referred to as height.

[0011] A combination appliance is a household appliance that combines a cooktop and a range hood. Specifically, a combination appliance is one that can be installed as a single unit in a kitchen. Preferably, the two components of the combination appliance—the cooktop and the range hood—are powered by a shared power supply, such as a common power cord. Furthermore, the two components can be controlled by a single control unit, which integrates controls for both components. For example, the two components can also be operated via a shared control panel, which can also be referred to as a user interface.

[0012] The combination appliance comprises a cooktop, a range hood, and an exhaust vent for the range hood. The cooktop has at least one cooking module. The cooktop also preferably includes a cover plate on which the cooking module(s) are arranged from below. The cover plate can, for example, be made of glass-ceramic. Each cooking module forms at least one cooking zone, that is, an area on which food can be heated on the cooktop. The cooking module can 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 includes at least one induction coil.An induction module is understood to be, in particular, a component designed to generate an alternating magnetic field by converting electrical energy. This field serves to induce eddy currents and / or remagnetization effects in a cooking container that is at least partially ferromagnetic, for example, a pot. These eddy currents are then converted into heat. The cooktop of the combination appliance according to the invention preferably includes at least two cooking modules. However, more modules, for example four or six, are also possible. Each cooking module forms a cooking zone.

[0013] The combination appliance also includes a range hood. A range hood is a device that extracts air, particularly contaminated air such as fumes and vapors, from the space above the cooktop downwards. Within the range hood, the air is cleaned and then released as purified air from both the range hood and the combination appliance. The range hood includes a fan for this purpose.

[0014] The extractor fan includes a blower. Here, a blower is understood to be a unit consisting of a fan, in particular a fan wheel, and a blower housing surrounding the fan. The fan is preferably a radial fan, in particular a radial fan with forward-curved blades, and the blower housing is preferably a spiral housing, which can also be referred to as a worm gear housing.

[0015] The extractor fan is located at least partially below the at least one cooking module. In particular, at least the fan is positioned downwards relative to the cooking module(s).

[0016] The blower has at least one air inlet opening. It also has an air outlet opening on the blower housing. The air inlet opening is located in, or formed by, the blower housing and is the opening through which air can be drawn into the blower housing by the fan. The air inlet opening is perpendicular to the axis of rotation of the fan wheel.

[0017] According to the invention, the blower is located below the extraction opening. The blower is arranged below the extraction opening such that the air inlet opening of the blower faces the extraction opening. The axis of rotation of the fan wheel is preferably located in the center of the extraction opening, that is, in the center of the surface of the extraction opening when projected perpendicularly onto the extraction opening.

[0018] The combination appliance has an extraction opening for the extractor hood. The extraction opening is the opening through which air from above the cooktop enters the combination appliance. The extraction opening for the extractor hood is also referred to as the extraction opening of the extractor hood. The extraction opening is integrated into the cooktop. Specifically, the extraction opening is located in a recess in the cooktop, particularly in the cooktop's cover plate. The extraction opening can be situated within the cooktop's recess or be formed by it. In the first case, the air inlet opening can, for example, be formed by the upper edge of a filter unit located in the recess. The cooktop's cooking modules are offset from the cooktop's recess.

[0019] The extraction opening preferably forms an elongated gap or slot extending in the depth direction of the cooktop. Preferably, the extraction opening is located in the center of the cooktop, and particularly in the center of the cooktop's cover plate. The width of the extraction opening is less than or equal to the distance between laterally adjacent cooking modules of the cooktop. The length of the extraction opening in the depth direction can correspond to the depth of the cooktop. Preferably, however, the extraction opening terminates at its rear end at a distance from the rear edge of the cooktop and at its front end at a distance from the front edge of the cooktop. Particularly preferably, the front end of the extraction opening is located at a distance from a control element that is arranged in the front area of ​​the cooktop and that is positioned in the middle of its width or, for example, extends across the width of the cooktop.

[0020] The extractor fan comprises a filter unit that includes at least one grease filter. The grease filter can, for example, consist of expanded metal filter layers. Particularly preferably, the filter unit also includes at least one odor filter. The filter unit is arranged at the extraction opening. In particular, the filter unit is arranged below the extraction opening and has a width greater than the width of the extraction opening. This arrangement of the filter unit allows the filter element(s), especially the grease filter and odor filter, to be positioned so that they do not obstruct the extraction opening at its upper end. This ensures the entry of air into the extraction opening and thus into the filter unit.

[0021] According to the invention, the extractor fan has a partition plate that separates the filter unit from the fan located below it. The partition plate is made of an airtight material. Preferably, the partition plate is made of a material that is also liquid-impermeable. For example, the partition plate can be made of plastic. The partition plate is arranged such that it separates the filter unit from the fan located below it. The partition plate covers the air inlet opening of the fan from above. A vertical gap is maintained between the air inlet opening of the fan and the partition plate, allowing airflow to the air inlet opening.

[0022] By positioning the fan below the extraction opening, placing the filter unit at the extraction opening, and incorporating a partition plate within the extractor hood to separate the filter unit from the fan below, several advantages can be achieved. In particular, positioning the fan below the extraction opening and the filter unit at the extraction opening allows for optimal use of the space beneath the cooktop. Specifically, this frees up space under the cooking modules for other components of the combination appliance. Furthermore, the airflow path of the extracted fumes and vapors to the filters of the filter unit is short. Finally, the partition plate prevents liquids from entering the fan's air intake and ensures targeted airflow within the extractor hood.Liquids can enter the system if food is accidentally spilled on the cooktop, dripping or running into the exhaust vent. Additionally, liquid collected on the filters of the filter unit can also drip down. Separating the fan from the filter unit with the partition plate prevents this liquid from entering the fan's air intake.

[0023] According to one embodiment, the partition plate has at least one recess. The recess can extend over the entire surface of the partition plate. In this case, the edge of the partition plate is formed, for example, by a raised strip of material. Alternatively, the recess extends only over a portion of the surface of the partition plate and is preferably located in the center of the partition plate. The recess in the partition plate allows a certain quantity of liquid to be retained or collected on the partition plate. The recess can therefore also be referred to as a collection container or collection channel. Preferably, the recess in the partition plate is connected to a separate reservoir for holding a larger quantity of liquid. In particular, the reservoir can be connected to an overflow of the recess.

[0024] According to the invention, the partition plate forms part of a housing for receiving the filter unit. The partition plate can, in particular, form the base of the housing. At least one of the side walls of the housing, especially the longitudinal walls of an elongated housing, is preferably formed by a grille. The housing can have airtight walls at its end faces. The housing is attached to the underside of the cooktop near the extraction opening. In an alternative embodiment not according to the invention, the housing can be attached to the extraction opening by means of a fastening element. For this purpose, the fastening element can extend downwards through the extraction opening and outwards along the underside of the cooktop to the sides. This allows the difference in width between the width of the extraction opening and the width of the housing, which is preferably greater, to be bridged.

[0025] Since the partition plate is part of a housing, in particular the base of a housing, and at least one side wall of the housing is a grille, the partition plate can, firstly, prevent liquids from entering the blower and, secondly, serve to hold at least one filter element of the filter unit. Furthermore, the at least one grille ensures airflow to the blower's air intake and can also serve as a support for at least one filter element. Finally, the grille and the partition plate prevent the user from accessing the interior of the combination unit, and in particular the blower, from above.

[0026] According to one embodiment, at least one grease filter in the filter unit is arranged at an angle. This allows the filter surface area of ​​the grease filter to be increased at a low height, and ensures controlled drainage of liquids along the grease filter compared to a horizontally oriented grease filter.

[0027] Preferably, the grease filter has a V-shape with the open end facing upwards. The grease filter can be a single piece or made of multiple parts. In particular, a filter element can be bent or folded to form the V-shape. Alternatively, the grease filter can consist of two filter elements, each forming one leg of the V-shape. The individual filter elements can be connected to each other directly or indirectly at the apex of the V-shape, or they can be separate and thus removable from the filter unit. By having a V-shape, the filter area can be maximized with a low profile. Furthermore, the angle of approach at which the air drawn in through the extraction opening flows onto the grease filter is improved. In particular, parallel airflow, which would occur with vertically oriented grease filters, can be prevented.

[0028] According to a preferred embodiment, the V-shaped grease filter is designed to be hinged. This can be achieved in a one-piece grease filter by selecting the appropriate filter material. Alternatively, for example, a weakening of the filter material can be incorporated at the apex of the V-shape in a one-piece filter element, allowing the filter element to be hinged and, in particular, folded together. In a two-piece grease filter, the individual filter elements can be pivotally attached to one another. This attachment can be direct or indirect. In particular, the filter elements can be connected to one another via a hinge or a connecting element to which each of the filter elements is pivotally attached. Because the grease filter is hinged, it can be removed from the extractor hood and thus from the combination unit by lifting it upwards through the extraction opening after it has been folded.The thickness of the grease filter is therefore preferably less than or equal to the width of the extraction opening. The length of the grease filter is preferably less than or equal to the length of the extraction opening.

[0029] According to one embodiment, the underside of the grease filter is held in a collection container. The collection container can be, in particular, an upwardly open rail or hollow profile, for example, a rectangular hollow profile with a slot in its upper surface. The grease filter is connected to, i.e., attached to, the collection container. By providing a collection container that holds the grease filter at its underside and is connected to it, liquid that drips from or runs down the grease filter can be collected. Furthermore, the grease filter, together with the collection container, can be removed from the extractor hood and cleaned. Finally, in the case of a two-part grease filter, the collection container can also serve as a connecting element, allowing the two filter elements of the grease filter to be hinged together. The width of the collection container is therefore preferably less than or equal to the width of the extraction opening.The length of the collection container is preferably less than or equal to the length of the extraction opening. In the embodiment of the collection container as a rail, an inwardly directed rib can be provided on each of the upper edges. This, or a hollow profile with a gap in the top, prevents accidental escape or overflow of accumulated liquid in the collection container when it is removed from the extractor hood. The collection container is preferably made of a liquid-tight material, for example, plastic or metal. The collection container can be placed on the partition plate of the extractor hood. If the partition plate has a recess, the collection container can be placed on or in the recess.

[0030] According to one embodiment, the filter unit has at least one odor filter, which is arranged laterally adjacent to the at least one grease filter within the filter unit. The odor filter can be in the form of a plate, mat, or molded body and may, for example, consist of activated carbon or contain activated carbon or other odor-binding substances. Preferably, the odor filter is arranged so that it is located downstream of the grease filter in the direction of airflow. The odor filter is located at the same height in the exhaust system as the grease filter. This reduces the space required in the vertical direction. Furthermore, in this arrangement, the at least one odor filter is positioned upstream of the fan in the direction of airflow. This allows the odor filter to dampen the noise caused by the fan. The at least one odor filter is preferably detachably held in the filter unit.This means that the odor filter can be moved within the filter unit and removed from it. For example, the odor filter can be mounted on the partition plate of the extractor hood and positioned against a wall of the housing, which is formed by a grille. This holds the odor filter downwards and to one side within the housing. Since the odor filter is located laterally adjacent to the at least one grease filter, and the grease filter preferably lies within the surface of the extraction opening in a perpendicular projection, the odor filter is positioned laterally outwards from the extraction opening, beneath a cooking module. From this position, the odor filter can be pulled towards the extraction opening after the grease filter has been removed and then extracted through it.The thickness of the odor filter is therefore preferably less than or equal to the width of the extraction opening, and the length of the odor filter is preferably less than or equal to the length of the extraction opening.

[0031] According to an alternative embodiment, the thickness of the odor filter is therefore preferably less than or equal to the width of the extraction opening, but the length of the odor filter is longer than the length of the extraction opening. In this embodiment, the odor filter is multi-part, meaning it consists of several filter elements. Each of the filter elements of the odor filter preferably has a length that is shorter than the length of the extraction opening. In this embodiment, for example, a central filter element of the odor filter can be removed, and then a front and subsequently a rear filter element of the odor filter can be moved into a position where they can be pulled in the width direction of the exhaust system towards the extraction opening and removed through it.The odor filter can therefore consist of, for example, two, three or four filter elements that are not connected to each other.

[0032] According to one embodiment, the combination appliance comprises at least one cooktop electronics unit and at least one extractor fan electronics unit, and these electronics units are arranged laterally to the fan. The electronics units can include control and operating components as well as a mains connection for the combination appliance. Power electronics are required to operate the cooktop and, in particular, the cooking module. The power electronics are used to supply the cooking module(s) with electrical energy. The power electronics can convert the electrical energy, for example, with respect to the voltage waveform or the current. The power electronics can include, for example, filter components and control electronics.The power electronics components include, for example, rectifiers for rectifying the AC voltage of the household electrical grid, inverters, and switching devices, such as those used for power management. Power electronics are also required to operate the extractor hood. Furthermore, control electronics are needed to operate the cooktop and the extractor hood. Preferably, a cooktop electronics unit and an extractor hood electronics unit are arranged on each side of the centrally located fan. By arranging the electronics units horizontally adjacent to the fan, the space requirement in the vertical direction is minimized. Preferably, by arranging a cooktop electronics unit and an extractor hood electronics unit on each side, the effort required to connect the cooking modules is reduced.Furthermore, the electronics required for the extractor hood can be divided between two electronic units, with, for example, the control electronics being separate from the operating electronics. The electronic units can have carriers on which the components are mounted. Additionally, each electronic unit can have an electronic housing in which the components, which may be mounted on carriers, are contained. Alternatively, the carriers with the components can be separated from the airflow in the extractor hood by one or more internal walls within a housing of the combined unit.

[0033] Preferably, the cooktop electronics unit is wider than the extractor fan electronics unit and is positioned above the extractor fan electronics unit. This arrangement ensures, firstly, that the cooktop electronics unit is close to the cooktop's cooking modules. Secondly, it optimizes the airflow from the filter unit, located above the fan, to the fan's air inlet. The electronics units are preferably positioned above the fan. This arrangement allows the fan to be the same size as the cooktop. The space between the top of the fan and the cooktop can accommodate the filter unit and the electronics units, which are positioned offset to the side.Thus, the combination device has a very compact design, but ensures, especially with the preferred arrangement of the electronic units where the electronic unit is narrower than the lower electronic unit, optimal airflow from the extraction opening to the blower.

[0034] According to a preferred embodiment, the combination appliance comprises a housing in which the components of the cooktop and the components of the extractor hood are jointly accommodated. In particular, the housing contains the fan, the filter unit, the extractor hood electronics unit, the cooktop cooking modules, and the cooktop electronics unit. The cooktop cover plate can also be accommodated in the housing. In this case, the cover plate is accommodated in the housing such that it forms the top of the combination appliance and additionally encompasses the upper edge of the housing. Alternatively, the cover plate can also be attached to the upper edge of the housing, or the housing can be attached to the underside of the cover plate.Because the combination unit has a single housing for the extractor hood and the cooktop, installation is simplified. In particular, the unit can be installed as a single component within a kitchen cabinet worktop. Furthermore, the shared housing eliminates the need to align the extractor hood components with the cooktop components during installation.

[0035] The invention thus creates a compact system that still ensures adequate filtration. The present invention provides a combination unit that can have a low profile without sacrificing storage space for the user, such as a drawer, at the bottom. Furthermore, the combination unit can be manufactured in a width suitable for installation in standard kitchens; for example, the combination unit can have a width of 60 cm.

[0036] The present invention will below be explained in more detail with reference to the accompanying figures. These show: Figure 1 : a schematic top view of a first embodiment of the combination device according to the invention; Figure 2 : a schematic sectional view of an embodiment of the combination device Figure 3: a schematic cross-sectional view of the cooktop in the area of ​​the extraction opening with grease filter; Figure 4 : a schematic cross-sectional view of the cooktop in the area of ​​the extraction opening with grease filter and odor filters; Figure 5 : a schematic sectional view of the upper area of ​​the combination device; and Figure 6 : a schematic sectional view of the filter unit of an embodiment of the combination device.

[0037] In Figure 1 Figure 1 shows a schematic top view of an embodiment of the combination appliance 1 according to the invention. The combination appliance 1 consists of a cooktop 10 and a range hood 11, of which in Figure 1 Only the extraction opening 111 is visible.

[0038] The cooktop 10 consists of a cover plate 100 and cooking modules 101 arranged below the cover plate 100. In the illustrated embodiment, two cooking modules 101 are provided. A recess 1000 is provided in the cover plate 100, forming the air inlet opening 111. In the illustrated embodiment, the recess 1000 is located in the center of the width of the cover plate 100 and extends in depth. In the illustrated embodiment, the recess 1000 has a rectangular, elongated shape. The length of the recess 1000, that is, its dimension in the depth direction, corresponds to the length of the cooking modules 101. The cooking modules 101 are arranged to the left and right of the recess 1000.

[0039] The cooking modules 101 are located below the cover plate 100 and are preferably attached to the underside of the cover plate 100. Alternatively, the cooking modules 101 can also be held in a cooktop housing (not shown), and the cover plate 100 is attached to the cooktop housing such that the cooking modules 101 are located in the immediate vicinity of or on the underside of the cover plate 100. If a cooktop housing is provided, it has an opening in the corresponding position of the recess 1000.

[0040] A control unit 103 is arranged in the front area of ​​the cooktop 10. In the illustrated embodiment, the control unit 103 is positioned in front of the recess 1000 in the cover plate 100 and can, for example, include touch controls, buttons, or rotary knobs. The control unit 103 can also contain a display (not shown). Depending on the configuration of the individual elements of the control unit 103, it can be arranged on, within, and / or below the cover plate 100. At least the control electronics (not shown) of the control unit 103 are arranged below the cover plate 100.

[0041] In the Figure 2 A schematic sectional view of an embodiment of the combination device 1 is shown.

[0042] The combination appliance consists of the cooktop 10 and the extractor hood 11. The combination appliance 1 has a housing 12 in which the components of the extractor hood 11 and the cooktop 10 are accommodated. Two cooking modules 101 of the cooktop 10 are shown, which rest against the underside of the cooktop's cover plate 100 and can also be referred to as induction modules. A mounting element 1140 is provided in the recess 1000. This mounting element has a removable grid in the recess 1000 and extends laterally beyond the recess 1000 on the underside of the cover plate 100. The opening of the fastening element 1140, which lies in the recess 1000, forms the extraction opening 111 of the extractor hood 11. A filter unit 114 is arranged below the recess 1000 and thus below the extraction opening 111. The filter unit 114 has a grease filter 1141 and two odor filters 115.The construction of filter unit 114 will be described later with reference to the . Figures 3 to 6 more precisely described. A housing 1142 for receiving the filter unit 114 is attached to the bottom of the mounting element 1140. The bottom of the housing 1142 forms a partition plate 1143.

[0043] The fan 110 of the extractor hood 11 is arranged on the base of the device housing 12, spaced downwards from the partition plate 1143. The fan 110 has a fan housing 1100 with an air inlet opening 1101 and an air outlet opening 1102 with a grille. The fan wheel 1103, which is driven by the motor 1104, is located in the fan housing 1100. The air inlet opening 1101 faces upwards, and the axis of rotation of the fan wheel is vertical and located below the air inlet opening 1101.

[0044] Above the fan 110, electronic units 102 and 112 are arranged laterally adjacent to the filter unit. The upper electronic unit 102 is the cooktop electronic unit, and the lower one is the extractor fan electronic unit 112. The cooktop electronic unit 102 is wider than the extractor fan electronic unit 112. Both electronic units 102 and 112 are arranged so that they abut the appliance housing 12 on one side. Thus, there is a step on the opposite side of the electronic units 102 and 112.

[0045] In Figure 3The extraction opening 111 with the grease filter 1141 is shown schematically. In this illustration, the extraction opening 111 of the extractor hood is formed by the recess 1000 in the cover plate 100 of the cooktop 10 or between the cooking modules 101. In this embodiment, the grease filter 1141 consists of two filter elements 11410, which are arranged at an angle to each other and form a V-shape. The underside of the filter elements 11410 are held in a collection container 1144. In the embodiment shown, the collection container 1144 is an upwardly open rail. The extraction opening 111 has a width D1 and the collection container 1144 has a width C. The width C is less than or equal to the width D1. The filter elements 11410 are pivotally attached to the collection container 1144. This allows, as in Figure 3As indicated by the double arrow, the grease filter 1141 can be folded by folding the filter elements 11410 together. In the folded state, the grease filter 1141 can be removed upwards through the extraction opening 111.

[0046] In Figure 4 A filter unit 114 with the filter element 114 and the two odor filters 115 is shown schematically. The grease filter 114 has the following features: Figure 3 The described structure is based on the swiveling mounting of the filter elements 11410 on the collection container 1144. Figure 4schematically indicated by dots. The collection container 1144 and the odor filters 115 are mounted on the separating plate 1143. The odor filters 115 are arranged laterally adjacent to the grease filter 1141. In particular, on each side of the grease filter 1141, an odor filter 115 is located below the cover plate 100, offset to the side from the recess 1000, which forms the extraction opening 111. After the grease filter 1141 has been folded and removed with the collection container 1144 via the extraction opening 111, one of the odor filters 115 can be slid on the separating plate 1143 towards the extraction opening 111 and removed upwards through it. This is shown in Figure 4 Indicated by arrows. The thickness F of the odor filter 115 is therefore less than the width of the recess 1000 and the extraction opening 111.

[0047] In Figure 5The upper section of combination device 1 is shown schematically. Here, space R, which is used for the arrangement of [items / components], is [description of the space]. Figure 5 The electronic units not shown are schematically indicated. In particular, two variants for the possible installation of electronic units are shown. On the left, a sloping partition wall is shown, against which electronic units can be installed to the left. On the right, the space is shown such that a wider electronic unit can be installed in the upper area and a narrower electronic unit in the lower area. In both variants, the distance between the odor filters 115 and the lateral ends of the partition plate 1143 is greater in the lower area (H2) than in the upper area (H1). Furthermore, in Figure 5 shown that below the separating plate 1143 there is a distance G to the one in Figure 5The blower (not shown), in particular the air inlet opening of the blower housing, is located at this distance G. The airflow from the odor filters 115 to the air inlet opening can thus be directed at this distance. The design of the filter unit corresponds to that shown in Figure 4 The setup shown is therefore not explained again.

[0048] In Figure 6 The filter unit 114 of the combination unit 1 is shown again in detail. The airflow through the filter unit 114 and to the air inlet opening 1101 is also shown. In this Figure 6 The housing 1142 for the filter unit 114 is also shown. In the illustrated embodiment, the partition plate 1143 has a recess 11430 in the center. Furthermore, in the illustrated embodiment, the partition plate 1143 forms the base of the housing 1142 for the filter unit 114. The side walls of the housing 1142 are each formed by a grid.

[0049] Thus, in the illustrated embodiment, the airflow that is in Figure 6 schematically shown, through the extraction opening 111, which is located in Figure 6 Air enters the extractor hood 11 through an opening in the top of the mounting element 1140. The air passes through the V-shaped grease filter 1141. The air, having passed through a filter element 11410, reaches an odor filter 115 in the filter unit 114 and passes through it. After exiting the odor filter 115 to the side, the air is deflected downwards and flows between the partition plate 1143 and the top of the blower housing 1100 to the air inlet opening 1101 of the blower housing 1100. From there, the air is distributed as described in Figure 2 shown, is directed via the fan wheel 1103 to the air outlet opening 1102 and exits the extractor hood 11 and also the combination unit 1 through an opening not shown in the device housing 12.

[0050] In the present invention, the grease filter is designed to be as large as possible in order to increase filter efficiency and minimize flow resistance. The width of the extraction opening is limited by the left and right cooking modules. The length of the extraction opening is designed to be as long as possible, ideally as long as the depth of the cooking modules. The height of the combination appliance is limited. In particular, the appliance must be so large that the storage space underneath, for example, drawer space, is only minimally utilized.

[0051] For this reason, the grease filter preferably has a V-shape and is hinged. A sealed container, which can also be called a collection container, is connected to the filter. The width of the collection container is less than the width of the extraction opening, in particular the recess in the cooktop.

[0052] The odor filters are preferably mounted outside the hinged grease filter, to the left and right of it. The thickness of the odor filters F is less than the width of the extraction opening D1 in the cooktop. The length of the odor filter can correspond to the depth of the extraction opening and is preferably less than the length of the odor filter. However, it is also within the scope of the invention for the odor filter to have a greater length than the depth of the extraction opening. In this case, the odor filter can be multi-part, with the individual parts being removable separately through the extraction opening. Each individual part has a length that is less than the depth of the extraction opening.

[0053] The cooking area electronics, especially the printed circuit boards, are usually arranged under the cooking pans to save space. In the invention, the electronics are preferably placed outside the air flow. The distance H does not necessarily have to be the same over the entire height of the filter. It can be constructed such that H1 < H2.

[0054] According to the invention, a separating plate ensures that the air flows through the grease filter and the odor filter and reaches the blower, which can also be referred to as a fan. A preferred distance G > 20 mm ensures that enough air reaches the fan wheel. The separating plate is preferably constructed such that it forms a trough. In the case where liquid flows in, the trough is preferably connected to a separate reservoir. Walls under the trough serve to prevent any liquid from entering the air inlet opening by capillary action and thus falling into the fan wheel and the motor.

[0055] A grid in the direction of flow downstream of the odor filter preferably serves as a stop for the filter and ensures that the user cannot interfere with the motor.

[0056] According to the invention, no separate ventilation system is installed under the cooktop; instead, a complete combination unit with both functions (cooking and ventilation) is provided. Preferably, only one housing is used. Reference sign
