Description

[0001] This patent application claims priority to German patent application DE102019202088.7, the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to a cooktop system. It also relates to a kitchen workspace incorporating such a cooktop system. Background Technology

[0003] WO2012 / 146237A1 discloses a flue gas extraction device for downward extraction of cooking steam. The cooktop system has an inlet opening through which cooking steam is extracted. The inlet opening is arranged in the central region of the cooktop system for efficient extraction of cooking steam. Disadvantageously, this arrangement of the inlet opening results in increased horizontal installation space requirements. Summary of the Invention

[0004] The purpose of this invention is to improve the furnace tray system.

[0005] This objective is achieved through a cooktop system having the features of claim 1. According to the invention, a cooktop system with a support for cooking items is known, wherein at least one heating unit and a flue gas extraction device for downward extraction of cooking steam must have an overall width of at least 600 mm to allow for particularly flexible use and installation. This cooktop system enables particularly dense utilization of available space in the kitchen. Especially in urban areas where living units are becoming increasingly smaller, this cooktop system can contribute to the dense and comfortable use of living space by reducing the amount of work surface required. Particularly advantageous is that this cooktop system can be inserted into kitchen base cabinets with a maximum storage space width of 600 mm, thereby greatly increasing design freedom in kitchen planning.

[0006] According to one aspect of the invention, the furnace plate system has at least two heating units, particularly at least three heating units, and especially at least four heating units. At least one heating unit can be configured as a radiant heating unit and / or an induction heating unit and / or a high-capacity heating unit and / or a slab heating unit. In particular, at least one heating unit can be designed to operate using electrical energy and / or gas.

[0007] According to one aspect of the invention, the overall width of the cooktop system, having a cooking utensil support, all heating units, and a flue gas extraction device, particularly with a fan and / or negative pressure duct, is at most 600 mm, particularly at most 580 mm, particularly at most 560 mm, particularly at most 500 mm, particularly at most 450 mm, particularly at most 400 mm, particularly at most 350 mm, and particularly at most 300 mm. The overall width of the cooktop system, having a cooking utensil support, all heating units, and a flue gas extraction device, particularly with a fan and / or negative pressure duct, is preferably at most 600 mm, particularly at most 550 mm, particularly at most 515 mm, particularly at most 500 mm, and particularly at most 450 mm. According to a particularly preferred embodiment, the overall width is at most 560 mm, and the overall depth is at most 515 mm. The overall width of the cooktop system should be understood as the extension of the cooktop system parallel to the front edge of the cooktop system facing the user, particularly parallel to the front edge of the cooking utensil support, and particularly in the horizontal plane. The overall depth should be understood as the extension of the cooktop system perpendicular to the front edge of the cooktop system facing the user, especially perpendicular to the front edge of the cooking item support, and especially in the horizontal plane.

[0008] According to one aspect of the invention, the ratio between the total depth and the total width is at least 0.8, especially at least 0.9, especially at least 1, especially at least 1.2, especially at least 1.5, especially at least 1.8.

[0009] According to another aspect of the invention, the flue gas extraction device has an inlet opening through which cooking steam can be extracted. For example, the inlet opening may be directly adjacent to or spaced apart from the edge region of the cooking item holder.

[0010] In a top view, the inflow opening can be circular, especially non-annular or annular and / or elliptical, or polygonal, especially triangular or quadrilateral or pentagonal or hexagonal.

[0011] According to one aspect of the invention, the hearth system includes power electronic components for supplying electricity to at least one heating unit. The power electronic components preferably include at least one, particularly at least two, and especially at least three power electronic circuit boards. A separate, independent power electronic circuit board can be provided for each heating unit. Preferably, at least one power electronic circuit board is designed to supply electricity to two heating units. All power electronic circuit boards can also be designed to supply electricity to two or more heating units. The heating units are preferably induction heating units. The power electronic components may accordingly include induction generators. Advantageously, by arranging the power electronic components on separate power electronic circuit boards, the power electronic components can be arranged in a particularly compact manner, and particularly flexibly relative to other components of the hearth system.

[0012] According to another aspect of the invention, at least one power electronic circuit board is vertically oriented and / or at least one power electronic circuit board is horizontally oriented. At least one power electronic circuit board may also be tilted in both the vertical and horizontal directions. Advantageously, this allows for a particularly flexible arrangement of the power electronic circuit boards, thereby saving installation space.

[0013] Preferably, at least one cooling fan is provided to cool the power electronic components. More preferably, at least one cooling fan is provided on each of at least two power electronic circuit boards. Therefore, cooling of the power electronic components can be performed particularly effectively and efficiently.

[0014] According to one aspect of the invention, at least two power electronic circuit boards are provided that are interconnected in a manner that transmits signals and / or transmits power. This connection can be achieved using flexible cables and / or rigid conductive rails.

[0015] Preferably, cooling elements are disposed on the power electronic components, particularly on at least two, and especially on all of the power electronic circuit boards. This allows multiple power electronic circuit boards to be effectively cooled with only a small number of cooling fans, particularly with only one cooling fan.

[0016] Preferably, the power electronics are designed to supply power to at least one heating unit and a flue gas extraction device, particularly at least one fan. For example, the fan control device for the flue gas extraction device can be integrated into the power electronics. In particular, the power electronics for supplying power to the flue gas extraction device can be arranged on the same power electronics circuit board as the power electronics for the at least one heating unit. This design is particularly space-saving and can be implemented economically. Preferably, at least one interface is provided on at least one power electronics circuit board for connecting external components, such as a window tilt sensor and / or a user interface.

[0017] In a top view, at least one power electronic circuit board is preferably arranged in the edge region of the cooktop system. The at least one power electronic circuit board is preferably arranged at a maximum distance of 50 mm, and more particularly a maximum of 20 mm, from the outer edge of the cooktop system. Therefore, the central region of the cooktop system can be used to draw cooking steam downwards. For example, at least one power electronic circuit board may be located in the front edge region and / or the rear edge region and / or the side edge region of the cooktop system.

[0018] According to another aspect of the invention, at least two power electronic component housings are provided for accommodating at least one power electronic circuit board, respectively.

[0019] According to another aspect of the invention, at least one partition wall is provided between two power electronic circuit boards. The partition wall may be a component of at least one power electronic component housing. The partition wall may be configured to protect the respective power electronic circuit boards from magnetic fields and / or electromagnetic radiation and / or moisture.

[0020] According to another aspect of the invention, the power electronic component housing and the cooking steam pipe of the flue gas extraction device, particularly the negative pressure pipe and / or positive pressure pipe, are formed in one piece, particularly integrated, and particularly with compatible materials. The power electronic component housing can be connected to the cooking steam pipe in a thermally conductive manner, particularly in a gas-tight manner relative to the cooking steam pipe, and / or in a flow-guiding manner. Therefore, advantageously, the cooking steam flow can be used to cool the power electronic component. For example, the control device for controlling the electric fan can be designed to control the electric fan according to the extraction of cooking fumes. Therefore, the cooktop system can operate in a particularly energy-efficient manner.

[0021] According to another aspect of the invention, the size of the cooking zone that can be heated by means of at least one heating unit, particularly in the main extension direction, and / or in diameter, is in the range of 50 mm to 300 mm, particularly in the range of 60 mm to 250 mm, and particularly in the range of 75 mm to 220 mm. Preferably, the diameter of the induction coil of each heating unit is in the range of 50 mm to 300 mm, particularly in the range of 60 mm to 250 mm, and particularly in the range of 75 mm to 220 mm. Preferably, the diameter of the main extension of at least one cooking zone and / or at least one induction coil is in the range of 50 mm to 120 mm, particularly in the range of 60 mm to 100 mm, and particularly in the range of 70 mm to 90 mm. Preferably, such induction coil is designed to transmit a maximum heating power of at least 300 W, particularly at least 400 W, particularly at least 500 W, and particularly at least 600 W. Accordingly, small but powerful heating units enable a particularly compact design of the cooktop system, particularly with an overall width of up to 600 mm.

[0022] The present invention also relates to a combined appliance comprising a cooktop system and a stove, particularly an oven, as described above. Preferably, the combined appliance is configured as an assembly unit. A flue gas extraction device may be air-guided to the interior space of the stove and / or the shell space surrounding the interior space of the stove. Preferably, the flue gas extraction device is air-guided to the interior space of the stove to generate a circulating airflow and / or extract cooking steam, particularly moisture. The flue gas extraction device may be air-guided to the shell space to provide a cooling airflow. The combined appliance can be implemented in a particularly compact and economical manner. In particular, the combined appliance can be easily and economically integrated into a kitchen base cabinet. For this purpose, the kitchen base cabinet can be designed with or without a back wall.

[0023] The main dimensions of the inlet opening, especially its diameter, are preferably at least 100 mm, especially at least 140 mm, especially at least 160 mm, and especially at least 170 mm. The main dimensions of the inlet opening, especially its diameter, are preferably a maximum of 250 mm, especially a maximum of 220 mm, especially a maximum of 200 mm, and especially a maximum of 180 mm. This allows for a very compact design of the cooktop system while achieving particularly efficient extraction of cooking steam.

[0024] According to another aspect of the invention, the flue gas extraction device includes at least one grease filter and / or at least one odor filter. The at least one odor filter may be disposed in a positive pressure duct, particularly downstream of at least one fan. Preferably, the at least one odor filter can be reversibly removed from the flue gas extraction device through an inlet opening. For this purpose, the flue gas extraction device may have a filter replacement space connecting the positive pressure duct and the negative pressure duct. Preferably, the filter replacement space can be reversibly closed. Therefore, the circulation of cooking steam through the filter replacement space during operation of the flue gas extraction device can be reliably prevented. To close the filter replacement space, a suction space closure for reversibly closing the negative pressure duct and / or a pressure space closure for reversibly closing the positive pressure duct are preferably provided. The suction space closure and the pressure space closure may be connected to each other in one piece.

[0025] According to another aspect of the invention, the maximum power output of at least one heating unit, particularly at least one induction coil, is in the range of 300 to 4000 watts. Preferably, the ratio of the maximum power of at least two heating units, particularly induction units, is at least 150%, especially at least 200%, especially at least 300%, especially at least 500%, especially at least 750%. The ratio of the main dimensions, especially the diameters, of at least two cooking zones is preferably at least 150%, especially at least 200%, especially at least 300%.

[0026] The cooktop system can have at least one cooking zone with a diameter of up to 100 mm, particularly up to 90 mm, particularly up to 80 mm, particularly up to 70 mm, and particularly up to 60 mm. The cooktop system can also have at least one cooking zone with a diameter of at least 160 mm, particularly at least 180 mm, particularly at least 200 mm, particularly at least 220 mm, and particularly at least 240 mm. On the one hand, providing particularly large and particularly small cooking zones increases the flexibility of the cooktop system's use. On the other hand, this allows for particularly good utilization of available installation space.

[0027] The smallest cooking zone can have a maximum power range of 300W to 800W, especially 400W to 600W. The largest cooking zone can have a maximum power range of 2000W to 5000W, especially 2500W to 4000W.

[0028] According to another aspect of the invention, the areal density of the maximum power of at least one induction coil is 0.05 W / mm². 2 Up to 0.15W / mm 2 Within this range, especially at 0.06W / mm 2 Up to 0.13W / mm 2 Within this range, especially at 0.07W / mm 2 Up to 0.12W / mm 2 Within the range. Preferably, the areal density of the maximum power of at least one induction coil is at least 0.1 W / mm². 2 Especially at least 0.12W / mm 2 Especially at least 0.14W / mm 2 Especially at least 0.15W / mm 2 Especially at least 0.2W / mm 2 Preferably, the ratio of the areal density of the maximum power of the two induction coils in the furnace system is at least 120%, particularly at least 130%, particularly at least 150%, and particularly at least 200%. According to another aspect of the invention, at least different induction coils are provided, wherein the areal density of the maximum power of the induction coil with the larger main size is at least 10%, particularly at least 20%, and particularly at least 50% lower than the areal density of the maximum power of the induction coil with the smaller main size.

[0029] According to another aspect of the invention, in a top view, the geometric center of the inlet opening is spaced apart from the geometric center of the cooking item holder. With respect to the depth and / or width of the cooktop system, the geometric center of the inlet opening can be arranged at the center of the cooking item holder. Particularly preferably, the geometric center of the inlet opening is arranged eccentrically with respect to the width of the cooking item holder and at the center of the cooking item holder with respect to the depth of the cooking item holder, or vice versa. Therefore, the inlet opening and cooking area can be arranged in a particularly space-saving and economical manner.

[0030] The invention also relates to aspects that are substantially independent but can be combined with the aforementioned features of the cooktop system, according to which the cooktop system is designed to be installed in different orientations, particularly in kitchen cabinets and / or kitchen workspaces. In particular, the cooktop system can be configured to be installed in a first or second orientation, wherein the cooktop system in the second orientation is rotated 90° or 180° relative to the first orientation about a vertical axis. The user interface of the cooktop system is preferably arranged on, and particularly attached to, a cooking item holder. The user interface can be designed to be rotationally symmetrical and / or can be arranged in different orientations on the cooking item holder, such that the user interface can be reversibly pivoted and / or may include a screen designed to display control information in a reversible manner. Therefore, the cooktop system can flexibly adapt to different installation situations.

[0031] According to another aspect of the invention, the cooktop system includes a mounting frame. The mounting frame is preferably designed for height-adjustable attachment of the cooktop system to a kitchen workspace and / or kitchen cabinet. This makes installation of the cooktop system very easy.

[0032] According to another aspect of the invention, the flue gas extraction device is located entirely below the cooking item support.

[0033] According to another aspect of the invention, the overall vertical installation height of the cooktop system, particularly including the overall vertical installation height of the cooking item support, all heating units, and flue gas extraction device, particularly including the overall vertical installation height of the fan and / or negative pressure duct, is a maximum of 300 mm, a maximum of 280 mm, a maximum of 250 mm, a maximum of 220 mm, a maximum of 200 mm, a maximum of 180 mm, a maximum of 160 mm, a maximum of 150 mm, a maximum of 120 mm, and a maximum of 100 mm. In principle, the overall installation height can also be greater.

[0034] According to another aspect of the invention, the flue gas extraction device has at least one, particularly at least two, and especially at least three fans for extracting cooking steam. Preferably, the cooktop system, including the cooking item support, all heating units, and the flue gas extraction device, especially the cooktop system with fans and / or negative pressure ducts, is designed as a combined appliance. Thus, the cooktop system can be installed in the workspace as a single piece, for example. This can significantly reduce assembly effort.

[0035] According to another aspect of the invention, the cooktop system includes exactly three heating units. Because the cooktop system has only three heating units, it can be designed to have a particularly small overall width. Given the simultaneous heating of different cooking items, the cooktop system with three heating units also provides sufficient flexibility.

[0036] According to another aspect of the invention, at least one inlet opening passes through the cooking utensil holder. This advantageously allows the inlet opening to be positioned particularly close to the heating unit. Therefore, cooking steam can be extracted directly at its origin. Consequently, the flue gas extraction device can operate in a particularly energy-efficient manner. The flue gas extraction device may also have two, three, or four inlet openings.

[0037] According to another aspect of the invention, the inflow pipe having a starting portion directly adjacent to the inflow opening is located adjacent to at least one inflow opening. The starting portion may have a central longitudinal axis configured to be inclined relative to the normal of the cooktop. The normal of the cooktop should be understood as a direction perpendicular to the working surface of the cooktop, and in particular, perpendicular to the working surface of the cooking item support. The angle between the central longitudinal axis and the normal of the cooktop is preferably in the range of 10° to 180°, particularly in the range of 30° to 60°, particularly in the range of 40° to 50°, and particularly exactly 45°.

[0038] According to another aspect of the invention, the flue gas extraction device has an inflow grille that can be arranged at at least one inflow opening. The inflow grille may have at least one guide element oriented, particularly in the direction of at least one heating element, for directional extraction of cooking steam. The guide element may be configured as a guide plate, particularly a thin sheet. Preferably, at least one guide element does not extend upward beyond the cooking item support. Alternatively, the guide element may extend beyond the cooking item support. Preferably, the inflow grille at least partially surrounds the inflow opening above the cooking item support. At least one guide element may shield the area of ​​the inflow opening away from at least one heating unit. For this purpose, the inflow grille preferably has a wall that at least partially shields the inflow opening in the horizontal direction and / or upward. Preferably, the inflow grille may be reversibly arranged on the inflow opening.

[0039] According to another aspect of the invention, the inflow grille does not completely cover the inflow opening. For example, the inflow opening may be elliptical in a top view, while the inflow grille may be circular in a top view. In this case, the inflow opening may completely surround the inflow grille in a top view. Thus, the cooking steam extracted through the inflow opening is not completely guided through the inflow grille, but only proportionally guided through the inflow grille.

[0040] According to another aspect of the invention, in a top view, the geometric center of at least one inflow opening is spaced apart from the geometric center of the cooking item support. This advantageously allows the cooktop system to be designed particularly compactly, especially in the horizontal direction.

[0041] According to another aspect of the invention, in a top view, at least one inflow opening is arranged at a distance from the geometric center of the cooking item holder in the width direction and / or depth direction. Since at least one inflow opening does not overlap the geometric center of the cooking item holder, a particularly compact design of the cooktop system can be ensured.

[0042] According to another aspect of the invention, the cooktop system has multiple heating units, wherein, in a top view, the minimum distance between the geometric center of the cooking item support and the first heating unit is at least twice the minimum distance between the geometric center of the cooking item support and the second heating unit. Thus, the cooktop system can be designed particularly compactly in the horizontal direction. This is especially suitable for using heating units of different sizes.

[0043] According to another aspect of the invention, in a top view, at least one heating unit is formed as a non-circular shape, particularly a quadrilateral, particularly a square or rectangle, or a triangle or hexagon, particularly a regular hexagon. Preferably, at least one heating unit and the inlet opening are each formed as a regular hexagon. This makes a particularly compact design feasible. Furthermore, the available area under the cooking utensil holder can be used particularly densely. The minimum distance between all heating units is preferably at most 40 mm, particularly at most 20 mm, and particularly at most 10 mm.

[0044] According to another aspect of the invention, the distance between at least one inlet opening and each heating unit differs by a maximum of 50%, particularly by a maximum of 30%, and especially by a maximum of 10%. Preferably, in a top view, all heating units are spaced the same from at least one inlet opening. This reliably ensures that cooking steam is extracted uniformly and efficiently above each heating unit.

[0045] According to another aspect of the invention, in a top view, the minimum distance between at least one inlet opening and at least one heating unit is at most 50 mm, particularly at most 30 mm, and especially at most 10 mm. Therefore, cooking steam can be extracted with particularly energy efficiency.

[0046] According to another aspect of the invention, in a top view, at least one heating unit overlaps the geometric center of the cooking item support. This allows for a particularly compact design of the cooking plate system in the horizontal direction.

[0047] According to another aspect of the invention, the furnace plate system has a user interface for controlling at least one heating unit and / or a flue gas extraction device. In a top view, the user interface can be arranged relative to at least one heating unit such that the user interface is opposite the inlet opening. Advantageously, this ensures a particularly compact arrangement of at least one heating unit, the inlet opening, and the user interface in the horizontal direction.

[0048] Furthermore, the purpose of this invention is to provide an improved kitchen workspace.

[0049] This objective is achieved through a kitchen workspace having the features of claim 15. As known from the invention, the kitchen workspace must include a kitchen base cabinet (with a storage space at a maximum width of 600 mm) and a cooktop system as described above, wherein at least one heating unit and a flue gas extraction device are arranged entirely within the storage space in a top view to ensure particularly dense utilization of space in the kitchen. The advantages of the kitchen workspace according to the invention correspond to the advantages of the aforementioned cooktop system. In particular, the features of the cooktop system can be utilized to further construct the kitchen workspace.

[0050] Storage space can be defined in the width direction by two perpendicular, parallel partition walls. Preferably, the partition walls are spaced a maximum of 600 mm apart. In a top view, the furnace plate system is preferably arranged entirely between the two partition walls. Preferably, at least one partition wall overlaps the flue gas extraction device and / or at least one heating unit in a side view. The partition walls can be designed to support the workspace. The furnace plate system can be fixed to the workspace.

[0051] According to another aspect of the invention, the kitchen cabinet has a rear wall. The rear wall may have a groove for allowing cooking steam pipes, especially positive pressure pipes connected to the stove system, to pass through.

[0052] According to another aspect of the invention, the kitchen cabinet has a fixing device for at least partially securing the stove system or positive pressure piping.

[0053] According to another aspect of the invention, the kitchen base cabinet has a partition wall to define the storage space for the stovetop system below.

[0054] Kitchen base cabinets may have heat insulation and / or sound insulation. This advantageously provides reliable protection of the space beneath the cooktop system against heat input and / or reduces noise emissions, especially during operation of the flue gas extraction system.

[0055] According to one aspect of the invention, a flue gas extraction device for downward extraction of cooking steam has at least one inlet opening for allowing cooking steam to flow in and at least one fan for drawing cooking steam from the at least one inlet opening, wherein the fan has a fan impeller rotatably mounted about an axis of rotation, and wherein the axis of rotation is oriented obliquely about the horizontal plane and about the vertical direction. Because the axis of rotation is oriented obliquely about the horizontal plane and the vertical direction, the flue gas extraction device can be integrated into the cooktop system in a particularly space-saving manner and can reduce flow deflection between the inlet opening and the at least one fan, thereby allowing cooking steam to be extracted in a particularly energy-efficient manner. The fan is preferably designed as a radial fan. The fan can also be designed as an axial fan or a crossflow fan.

[0056] According to a particularly preferred embodiment of the flue gas extraction device, the negative pressure duct of the exhaust pipe of the flue gas extraction device extends downward beyond at least one fan by a maximum of 50 mm, particularly a maximum of 25 mm, and especially a maximum of 10 mm. More preferably, at least one fan extends downward beyond the negative pressure duct in the vertical direction. Therefore, a particularly low installation height of the flue gas extraction device can be ensured.

[0057] According to another aspect of the invention, the tilt angle between the horizontal plane and the rotation axis of at least one fan is in the range of 10° to 85°, particularly in the range of 30° to 80°, and particularly in the range of 60° to 75°. The tilt angle may also be exactly 45°.

[0058] According to another aspect of the invention, the direction of suction of cooking steam in at least one fan has an upward component. The angle between the horizontal plane and the suction direction is preferably at least 45°, especially at least 60°, and particularly at least 80°. Because the suction direction has an upward component, the fan can be reliably protected from liquid ingress.

[0059] According to another aspect of the invention, a negative pressure conduit connects at least one inlet opening to at least one fan in a flow-guiding manner. The centerline of the negative pressure conduit preferably has an absolute angular variation along its extension of a maximum of 170°, particularly a maximum of 150°, particularly a maximum of 120°, and particularly a maximum of 100°. The absolute angular variation is preferably at least 100°, particularly at least 120°. The absolute angular variation should be understood as the integer absolute value of the curvature of the conduit centerline along its extension. Thus, cooking steam can be extracted in a particularly energy-efficient manner while avoiding turbulence, wherein at least one fan can be reliably protected from liquid ingress.

[0060] According to another aspect of the invention, the centerline of the pipe has no inflection point. Therefore, cooking steam can be conducted in the negative pressure pipe in a particularly laminar flow manner.

[0061] According to one aspect of the invention, at least one fan overlaps with at least one heating unit in the top and side views and / or the front view. The heating unit preferably has power electronic components for supplying electricity to the heating element. Preferably, in the top and side views and / or the front view, at least one fan, particularly the fan impeller of at least one fan, overlaps with the power electronic components and / or control unit and / or user interface of the hearth system. This advantageously allows the hearth system, particularly in the vertical direction, to be designed to be exceptionally compact.

[0062] According to an independent aspect of the invention, a fan for drawing cooking steam has a fan housing with a negative pressure connection opening and a fan impeller arranged in the fan housing and rotatably mounted about a rotation axis, wherein the rotation axis includes a connection angle having a connection normal perpendicular to the orientation of the negative pressure connection opening, the connection angle being in the range of 10° to 85°, particularly in the range of 30° to 80°, and particularly in the range of 60° to 75°. This advantageously allows the fan to be connected particularly easily to the starting portion of a negative pressure duct. In particular, the connection area of ​​the starting portion can be oriented substantially vertically or horizontally. Therefore, the use of intermediate elements connecting the starting portion to the negative pressure connection opening can be avoided. Thus, the fan can be used in a particularly economical manner for flue gas extraction devices that draw cooking steam downwards and / or for cooktop systems.

[0063] Preferably, the flue gas extraction device has at least three, especially at least four, especially at least five, especially at least six, especially at least eight fans. This allows the flue gas extraction device to be designed to be particularly compact, i.e., with reduced installation space, and to operate with particularly low noise. The at least three fans can be designed as axial fans and / or radial fans and / or cross-flow fans. The large number of fans allows for the use of smaller and / or quieter fans while maintaining extraction performance. Compared to axial fans, cross-flow fans have a smaller diameter while providing the same extraction performance, thus making the flue gas extraction device particularly compact.

[0064] According to one aspect of the invention, at least one fan has a fan impeller with a maximum diameter of 250 mm, particularly 200 mm, especially preferably 180 mm, particularly 150 mm, particularly 120 mm, particularly 100 mm, particularly 80 mm, and particularly 50 mm. The flue gas extraction device can therefore be designed to be particularly compact. The flue gas extraction device occupies little installation space.

[0065] In principle, fans with larger impellers can also be used, especially impellers with diameters of 160mm, 200mm, or up to 250mm. In particular, fans with four impellers, each with a diameter of 160mm, can be used. The impellers can each have an installation height of 80mm or less, especially 50mm or less.

[0066] Preferably, the installation height of the flue gas extraction device is a maximum of 220 mm, a particularly maximum of 200 mm, a particularly maximum of 150 mm, a particularly maximum of 120 mm, and a particularly maximum of 100 mm. This advantageously allows the flue gas extraction device to be designed to be particularly compact. The space below the flue gas extraction device can largely be retained as storage space, such as storage space for cooking utensils.

[0067] According to another aspect of the invention, at least one fan is connected to each other in a ducted manner via a negative pressure conduit of the flue gas extraction device. The negative pressure conduit of the flue gas extraction device extends between at least one inlet opening and at least one fan. Preferably, all fans are connected to each other in a ducted manner via negative pressure conduits. At least one fan may be connected to at least one inlet opening via a single negative pressure conduit. Alternatively, the flue gas extraction device may have multiple inlet openings, each inlet opening being connected to a fan in a ducted manner via a separate negative pressure conduit. Preferably, all fans can be driven independently of each other, particularly by means of corresponding control devices. Preferably, cooking fumes can be extracted independently of each other via single inlet openings. To change the extraction performance, all or a single fan can be activated as needed. Thus, a single fan can always operate at an optimal speed, which is determined in particular by the geometry of the fan impeller, and at which the fan impeller operates efficiently and quietly, wherein the extraction performance remains controllable by activating a reduced number of fans compared to the total number of fans.

[0068] The flue gas extraction device can have filters for filtering cooking steam. Since multiple fans are connected to each other via negative pressure ducts, the number of filters can be less than the number of fans. Therefore, the flue gas extraction device is particularly easy to maintain and can be implemented in a compact manner. Preferably, the flue gas extraction device is configured such that each fan extracts cooking steam through each filter, particularly through a single filter.

[0069] According to another aspect of the invention, the filter is arranged vertically adjacent to at least one inlet opening and / or the surface of the cooking item holder, particularly the surface of the cooking item holder, and / or arranged flush with the surface of the cooking item holder. In a top view, the filter may completely overlap with the cooking item holder or may be arranged behind the cooking item holder. By arranging the filter in this way, the flue gas extraction device can be designed to be particularly space-saving and have a particularly low installation height.

[0070] The filter can be bonded to the cooking appliance holder and / or connected to the cooking appliance holder via a filter container, particularly in a form-fit manner, especially via a track. Preferably, the filter can be reversibly removed from the flue gas extraction device, particularly from the cooking appliance holder, especially without tools. The filter can be designed as a grease filter. Preferably, in a top view, the area of ​​the filter covered by the cooking appliance holder is at least 50% of the area of ​​the cooking appliance holder. This ensures energy-efficient filtration of cooking steam.

[0071] The flue gas extraction device may have at least one cover for covering at least one inflow opening. The cover may be arranged parallel to the surface of the cooking item holder, particularly flush with the surface of the cooking item holder. The cover may have multiple, particularly at least ten, particularly at least fifty, particularly at least one hundred cover openings for extracting cooking steam. The cover may be formed as a grille or metal mesh. The cover may include glass, particularly glass-ceramic, or metal, particularly stainless steel. Preferably, the cover is adapted to the cooking item holder, particularly in color and / or structure, in such a way that the cover and the cooking item holder are visually almost indistinguishable from each other or not at all.

[0072] The filter may have at least one cover and at least one filter element. The cover may be reversibly connected to the filter element. The filter may have a collection tray for collecting spilled liquid. For example, the filter may have a triangular cross-section.

[0073] According to one aspect of the invention, the flue gas extraction device has at least one fan motor, which is rotaryly driven by at least two, and especially at least three, fans. Preferably, all fans are rotary driven by a single fan motor. For this purpose, the fan motor can be rotaryly driven by one or more rotary transmission devices, especially one or more gearboxes and / or belt drives, to the respective fan impellers of the at least two, and especially at least three fans. The fan motor can be rotaryly driven connected to or disconnected from the fan impellers, especially via a switchable coupling device. Typically, the number of fan motors can be less than the number of fans, especially less than the number of fan impellers. This aspect is also advantageous, independent of other details of the invention.

[0074] According to another aspect of the invention, the flue gas extraction device includes at least one odor filter, particularly an activated carbon filter, arranged in a negative pressure duct. Preferably, the filter is configured as a combination filter, wherein the combination filter includes a grease filter and an odor filter. The odor filter arranged in the negative pressure duct is particularly easy to remove in a reversible manner, especially via at least one inlet opening. Therefore, the flue gas extraction device is particularly easy to maintain.

[0075] According to another aspect of the invention, at least two fans have rotation axes that are tilted toward each other. This should be understood as at least two fans having rotation axes that are not parallel to each other. The rotation axis of at least one fan can be oriented vertically and / or horizontally. The rotation axis of at least one fan can also be arranged in an oblique manner relative to the vertical direction, wherein the angle relative to the vertical direction is greater than 5° and less than 85°. The rotation axes of at least two fans can be oriented radially with respect to the upstream negative pressure duct and / or with respect to a vertical axis, particularly a vertical axis extending through the geometric center of the inflow opening. Thus, at least two fans can be arranged on the negative pressure duct in a particularly space-saving manner. The angle between the rotation axes of at least two fans is preferably at least 30°, particularly at least 45°, and particularly 90°.

[0076] According to another aspect of the invention, the flue gas extraction device includes at least one guide element adjacent to at least one inlet opening and displaceable in a vertical direction to shield an upper space upstream of at least one inlet opening on one side. The upper space should be understood as the space above the flue gas extraction device from which cooking steam is extracted downwards. The guide element is preferably plate-shaped. At least one guide element surrounds at least one inlet opening on one side, that is, not completely surrounds at least one inlet opening. In a top view, at least one guide element surrounds at least one inlet opening, particularly starting from the center of the geometric area of ​​the inlet opening, preferably at an angle of at least 30°, particularly at least 45°, particularly at least 90°, particularly at least 120°, particularly at least 180°. Therefore, cooking steam can be extracted directionally and particularly energy-efficiently.

[0077] The effectiveness of the guide element depends primarily on its height. Preferably, at least one guide element extends upward in the vertical direction from at least one inflow opening by at least 50 mm, particularly at least 100 mm, particularly at least 150 mm, and particularly at least 200 mm.

[0078] At least one guide element may be flat or bent once or twice, meaning it cannot be coiled. The cross-section of at least one guide element is preferably annular.

[0079] At least one guide element may have a lighting device. At least one guide element may also have a user interface for controlling at least one fan and / or at least one cooktop.

[0080] Preferably, at least one guide element is displaceable relative to at least one inflow opening. For this purpose, the flue gas extraction device can have a guiding device, particularly a sliding guide element. Preferably, at least one guide element can be arranged between a guiding position (in which the upper space is shielded on one side) and a reset position (in which cooking steam is extracted without being affected by at least one guide element).

[0081] According to another aspect of the invention, the upper side of at least one guide element in the reset position may be arranged below or flush with the adjacent inflow opening. Therefore, the area above the inflow opening can be used to place cooking items without damage from at least one guide element.

[0082] Preferably, the guide element includes a closing element for closing at least one inflow opening in the reset position, particularly for hermetically closing at least one inflow opening.

[0083] In the top view, in the guide position, at least one guide element preferably at least partially covers at least one inflow opening. Therefore, cooking steam can be extracted in a more directional manner and thus with particularly high efficiency.

[0084] According to another aspect of the invention, the area of ​​at least one inflow opening is at most 100 mm. 2 Especially the largest is 10mm 2 Especially the largest is 1mm 2 Especially the maximum is 0.1mm 2 The number of inlet openings is preferably at least ten, especially at least twenty-five, especially at least fifty, especially at least one hundred, and especially at least one thousand. Therefore, cooking steam can be extracted from multiple different locations where cooking steam is generated and from places directly adjacent to where cooking steam is generated. Thus, the extraction of cooking steam is particularly efficient.

[0085] According to another aspect of the invention, a plurality of inlet openings are respectively associated with one of at least two extraction sections, wherein cooking steam can be extracted independently via each extraction section. The inlet openings of each of the at least two extraction sections can be respectively connected to negative pressure ducts that are airtightly separated from each other. Preferably, each of the at least two extraction sections is respectively connected to at least one fan for extracting cooking fumes in a ductile manner, particularly via separate negative pressure ducts. Preferably, each of the at least two extraction sections includes at least one, particularly at least two, particularly at least five, particularly at least ten, particularly at least fifty inlet openings.

[0086] Another objective of this invention is to improve the furnace tray system.

[0087] This objective is achieved by a cooktop system having a flue gas extraction device according to the above description and a cooktop for heating cooking items. The advantages of the cooktop system according to the invention correspond to the advantages of the aforementioned flue gas extraction device. Preferably, the cooktop includes at least one cooking item support and at least one heating unit arranged below the cooking item support. The at least one heating unit can be designed as a radiant heating unit and / or an induction heating unit. The at least one heating unit, especially an induction coil, can have a diameter or length and width of up to 23 cm, especially up to 24 cm, especially greater than 24 cm. The cooktop system can particularly have four cooktops with a diameter or length and width of 24 cm each.

[0088] At least one inflow opening is preferably located at the rear third, especially the rear quarter, of the furnace tray system in a top view. At least one inflow opening preferably extends over at least 50%, especially at least 70%, especially at least 85% of the width of the furnace tray system.

[0089] According to one aspect of the invention, the cooking utensil holder completely overlaps with all the fans in a top view. Therefore, the horizontal dimensions of the cooktop system are particularly small.

[0090] According to another aspect of the invention, in a top view, the fan is arranged in the area behind the rear edge of the cooking item support. This allows the cooktop system to be positioned in the front area, particularly in the cooktop area (also referred to as the cooking zone) with a particularly low installation height. The cooktop system in the front area, particularly in at least 50%, at least 70%, at least 80%, and at least 90% of its extension, has an installation height of at most 10 cm, at most 5 cm, and at most 4 cm in a direction perpendicular to the front edge. This description of the installation height of the cooktop system is particularly applicable to the entire area where the cooktop is arranged. Therefore, the low installation height of the cooktop system in this area allows full utilization of the space in the lower cabinet. In particular, there is no need to omit the top drawer. If necessary, the top drawer can be designed with a slightly reduced insertion depth.

[0091] According to another aspect of the invention, the cooktop system has an L-shaped cross-section. In particular, the cooktop system can have a lower mounting height in its front region, especially in the region where the cooktop is arranged, compared to its rear edge region. In this case, electronic components and / or one or more fans, especially one or more fan impellers, can be arranged in the rear edge region, for example.

[0092] According to another aspect of the invention, the cooktop system may have an L-shaped cross-section in the transverse direction. In particular, the cooktop system may have a greater mounting height in one or two of its edge regions compared to its central region. This also allows the cooktop system to have a particularly low mounting height in its central region. In particular, electronic components and / or fans or components thereof and / or other components of the cooktop system may be arranged in the edge regions, especially in the rear and / or side edge regions.

[0093] According to one aspect of the invention, the filter is arranged in a top view between at least two furnace trays or behind at least one furnace tray.

[0094] According to one aspect of the invention, at least one inlet opening is designed to be breathable and liquid-repellent, especially liquid-tight. For this purpose, a breathable and liquid-repellent layer, especially a liquid-tight layer, can be disposed on at least one inlet opening, particularly on the cooking item holder. The breathable and liquid-repellent layer can be disposed above or below the cooking item holder. The breathable and liquid-repellent layer can be attached to the cooking item holder and / or at least one filter, particularly in a substantially adhesive or removable manner. Preferably, the breathable and liquid-repellent layer is designed to be cleanable, particularly dishwasher-safe. This ensures reliable downward extraction of cooking steam without liquid seeping into the area below the cooking item holder and / or at least one inlet opening.

[0095] At least one inflow opening may define an inflow channel passing through the cooking item holder upstream. The at least one inflow channel may be formed as a hole, particularly a micropore and / or a perforation. Preferably, at least one inflow opening is arranged in the central region of the cooking item holder in a top view, particularly in the region at the center of the geometric area of ​​the cooking item holder. In a top view, at least one inflow opening may be arranged in the edge region of the cooking item holder.

[0096] According to one aspect of the invention, in a top view, the surface portion of the perforated surface of the cooking item holder is at least 30%, particularly at least 50%, particularly at least 75%, and particularly 100% of the total surface area of ​​the cooking item holder.

[0097] According to one aspect of the invention, at least one cooking item holder can be reversibly removed from the cooking item holder container of the cooktop system, especially without the need for tools.

[0098] Cooking dish holders can be designed as separate structural elements, detachable from other components of the cooktop system. They can also be separated from, and in particular removed from, the other components of the cooktop system along with the induction generator.

[0099] Cooking dish racks can be dishwasher cleanable and / or designed to be cleaned during pyrolysis. In particular, cooking dish racks can be designed to be scratch-resistant and / or corrosion-resistant and / or heat-resistant, especially for temperatures of at least 200°C, especially at least 300°C, especially at least 400°C, especially at least 500°C.

[0100] At least one cooking item holder can also be designed as a capacitive and / or electrically heated insulation plate, especially one that can be removed and / or carried without tools. For electric heating, the insulation plate may have a mica layer. Preferably, the insulation plate can be heated to a maximum temperature of 120°C, particularly a maximum of 100°C, and especially a maximum of 80°C. Preferably, the cooking item holder has a specific heat capacity of at least 500 J / kgK, particularly at least 700 J / kgK, and especially at least 850 J / kgK.

[0101] According to another aspect of the invention, the furnace plate system is configured as a compact appliance. A compact appliance should be understood as an assembly unit comprising a furnace plate and a flue gas extraction device, wherein the flue gas extraction device includes a negative pressure duct and at least one fan. The furnace plate system designed as a compact appliance can be installed particularly quickly and cost-effectively, especially in workspaces.

[0102] According to another aspect of the invention, at least one fan is horizontally and completely positioned behind the geometric center of the cooktop system in a top view, particularly behind the geometric center of the cooking item support. Therefore, the overall installation height of the cooktop system can be particularly low. When the cooktop system is installed on a kitchen base cabinet, the available storage space below the workspace is largely unaffected by the cooktop system, especially in the front area. Preferably, at least one fan is positioned completely behind the cooking item support in a top view. In this case, the rotation axis of at least one fan can be horizontally oriented, particularly in the depth direction of the cooktop.

[0103] According to another aspect of the invention, in the horizontal region between the front edge of the hearth system and the center of its geometric area, the front mounting height of the hearth system is at most 180 mm, particularly at most 150 mm, particularly at most 120 mm, particularly at most 100 mm, particularly at most 80 mm, particularly at most 50 mm. It has been found that the hearth system can have a mounting height of 40 mm in the front region.

[0104] The cooktop system has a low installation height, especially in the area extending at least 30cm, particularly at least 40cm, and particularly at least 50cm from the front edge in a direction perpendicular to the front edge.

[0105] Cooktop systems can have a low installation height, especially throughout the entire cooking area.

[0106] The overall installation height of the furnace plate system is preferably no more than 250mm, especially 200mm, and especially 150mm.

[0107] Another objective of this invention is to improve a furnace plate system with a furnace plate cover.

[0108] This objective is achieved by a cooktop system having the features of claim 13. According to the present invention, a cooktop system with a cooktop cover, which is displaceable relative to the cooktop, can be utilized particularly flexibly and densely, and in a top view, the cooktop cover at least partially covers at least one inlet opening and at least one cooking zone in a closed position and exposes at least one inlet opening and at least one cooking zone in an open position. The cooking zone is defined as the area above the cooking item support, in which at least one heating unit heats the cooking item.

[0109] When the cooktop lid is in the open position, the entire cooktop can be used for heating food in a conventional manner. When the cooktop lid is in the closed position, for example, a first area above the cooktop can be used for heating food, while a second area above the cooktop can be used simultaneously for preparing food. By at least partially covering one inlet opening, the extraction strength is increased in the uncovered area of ​​the inlet opening, especially while the fan power remains unchanged. Therefore, increased extraction performance can be provided in the cooktop area used for cooking. In addition, the cooktop lid in the open position can reliably protect the wall behind it from grease splattering. Thus, available space in the kitchen can be utilized efficiently, and cooking steam can be extracted energy-savingly.

[0110] According to another aspect of the invention, the cooktop lid, in the closed position, covers only at least one inlet opening and does not cover the cooking area. In particular, the cooktop lid, in the closed position, can be flush with the rear edge of the cooktop, especially with the rear edge of the cooking item support.

[0111] The upper side of the cooktop lid can be designed to be mechanically insensitive, particularly a scratch-resistant storage surface and / or a cut-resistant cutting surface. When the cooktop lid is in the closed position, the upper side of the lid can then be used, for example, for preparing food to be heated. Preferably, the cooktop lid is designed to be heat-resistant, particularly for temperatures of at least 150°C, especially at least 200°C, and especially at least 250°C. The cooktop lid can have particularly low thermal conductivity, at most 3.0 W / mK, especially at most 2.0 W / mK, and especially at most 1.0 W / mK. Therefore, heated food can be placed on the cooktop lid without the risk of damaging the lid or burning the skin on the heated lid.

[0112] In particular, the stove lid can be made of metal, especially cast iron, glass or glass ceramic, or plastic materials.

[0113] The furnace tray cover is preferably pivotally mounted on the furnace tray system, and more particularly on the furnace tray itself. The furnace tray cover can communicate with a drive mechanism to displace the furnace tray cover between a closed position and an open position. The drive mechanism may include a motor and / or a spring element. Therefore, the furnace tray cover can be displaced between the closed and open positions particularly easily, and especially automatically. For manual displacement between the open and closed positions, the furnace tray cover may have a handheld device.

[0114] Preferably, the cooktop cover, in the closed position, completely covers at least one inlet opening and / or at least one cooking zone. In a top view, the cooktop cover, in the closed position, may completely overlap the entire cooktop, particularly the entire cooking item support. The cooktop cover, in the closed position, may be supported on the cooktop, particularly on the cooking item support. In the closed position, the surface of the cooktop cover may be arranged flush with or extending upwards beyond the workspace.

[0115] According to one aspect of the invention, the furnace plate cover hermetically closes at least one inflow opening in the closed position. For this purpose, the furnace plate cover may have a closing seal. Preferably, in the closed position, the closing seal completely surrounds at least one inflow opening. Therefore, odors can be reliably prevented from escaping from the flue gas extraction device through at least one inflow opening, especially when the fan is not running.

[0116] According to another aspect of the invention, the cooktop cover comprises at least two independently displaceable cover bodies. Preferably, at least one inlet opening and the cooking item support can each be partially covered by at least two cover bodies. Thus, unused areas of the cooking item support can be covered together with portions of at least one inlet opening, particularly adjacent portions, where another portion of the cooking item support can be used specifically for heating the cooking item. Cooking steam can be extracted particularly densely via the thus reduced inlet opening area.

[0117] The furnace cover may have at least one closed cover attached to at least one cover body. The closed cover may be configured such that, in the closed position of at least one cover body, the closed cover extends into the negative pressure duct of the flue gas extraction device. A closure seal is preferably arranged at at least one closed cover. Thus, at least one inflow opening can be closed particularly reliably, especially in an airtight manner.

Detailed Implementation

[0134] In the following text, refer to Figure 1 and Figure 2 The following describes the various details of a cooktop system 1 having a cooktop 2 and a flue gas extraction device 3. The cooktop 2 includes a cooking dish support 4 with four heating units 5 arranged thereon for heating cooking dishes 6. The cooktop system 1 is mounted on a kitchen cabinet 7. For this purpose, the cooktop system 1 is attached to the workspace 8 of the kitchen cabinet 7. The surface of the cooking dish support 4 is arranged flush with the surface of the workspace 8.

[0135] To control the flue gas extraction device 3 and the heating unit 5, the furnace plate system 1 includes a user interface 9. The user interface 9 is designed as a touch-sensitive screen. The user interface 9 is signal-communicated with the flue gas extraction device 3 and the heating unit 5 via a control unit (not shown).

[0136] The cooking utensil holder 4 includes a glass plate, particularly a glass-ceramic plate. Multiple inlet pipes 10 pass through the glass plate to extract cooking steam. The cross-sectional area of ​​each inlet pipe 10 is less than 1 mm². 2 .

[0137] A cooking zone 11 is formed in the area horizontal to or above the cooking item holder 4, which can be heated by the various heating units 5. Within the cooking zone 11, the heating units 5 can act on and heat the cooking item 6. Within the cooking zone 11, the cooking item holder 4 does not have any inflow pipes 10. Outside the cooking zone 11, the inflow pipes 10 are arranged equidistantly on the cooking item holder 4 in a top view. The inflow pipes 10 extend through the cooking item holder 4 in a straight line and in the vertical direction. The inflow pipes 10 have an annular cross-section.

[0138] like Figure 2 As shown, the cooking plate system 1 has a housing 12. A cooking item support container 13 is disposed on the housing 12. A cooking item support 4 is supported above on the cooking item support container 13 and can be reversibly removed from the cooking item support container without tools. The cooking item support container 13 has an inclined edge (not shown). The inclined edge defines a support surface of the cooking item support container 13 with a recess. The recess is designed such that by loading the cooking item support 4 in a downward direction in the region above the recess, the region of the cooking item support 4 opposite to the inclined edge can be raised.

[0139] The cooking dish rack 4 is designed to be dishwasher safe. In particular, the cooking dish rack 4 is designed to be heat resistant, especially to temperatures of at least 350°C, and is suitable for pyrolysis cleaning.

[0140] The number of inflow pipes 10 passing through the cooking item holder 4 is greater than 50. A filter 14 is arranged below the cooking item holder 4, particularly in the area traversed by the inflow pipes 10. In a top view, the filter 14 completely overlaps with the inflow pipes 10. The filter 14 is designed as a combination filter to filter grease and odors from cooking steam. The cooking item holder 4 has a filter container 15. The filter 14 is reversibly attached to the cooking item holder 4 by means of the filter container 15.

[0141] The cooking item holder 4 is permeable to gas but impermeable to liquid. For this purpose, the cooking item holder 4 has a hydrophobic surface coating 16 in the area flowing into the pipe 10.

[0142] A filter 14 is arranged in the negative pressure duct 17 of the flue gas extraction device 3. The negative pressure duct 17 extends between the inlet opening 18 formed by the inlet duct 10 on the upper side of the cooking item support 4 and the fan 19 of the flue gas extraction device 3. The flue gas extraction device 3 includes four fans 19. The fans 19 are designed as cross-flow fans. The rotation axis 20 of each fan 19 is oriented horizontally, in particular parallel to the front edge 20a of the cooktop system 1. The fans 19 are connected to the inlet opening 18 via the negative pressure duct 17 and to the cooking steam outlet 21 via the negative pressure duct 21.

[0143] The flue gas extraction device 3 is designed to extract cooking steam via four independently operable extraction sections 22a, 22b, 22c, and 22d. For this purpose, each extraction section 22a, 22b, 22c, and 22d is connected to one of the fans in the fan 19 via a separate negative pressure duct 17. The surface of the cooking item holder 4 is divided into four extraction sections 22 with equal areas.

[0144] A sealing element (not shown) is provided at the negative pressure pipe 17 to airtightly connect the negative pressure pipe 17, which is located downstream of each extraction section 22, to the cooking item holder 4. The sealing element completely surrounds each extraction section 22.

[0145] The cooking utensil holder 4 has a depth T of 500 mm. In the front region of the cooktop system 1, particularly in the front region extending at least 70% of the depth T from the front edge 20a of the cooktop system 1, the cooktop system 1 has a front mounting height H of 120 mm or less. v The installation height H of the furnace tray system 1 v In this area, the space can be limited to only 3cm to 5cm. The storage space 23 of the kitchen base cabinet 7 is largely unaffected and unobstructed by the stovetop system 1. The top drawer 24 of the kitchen base cabinet 7 is not shortened in either the vertical or depth direction. If necessary, the top drawer 24 of the kitchen base cabinet 7 can be configured to be shorter in the depth direction to provide sufficient usable space in the rear area for accommodating the fan 19.

[0146] Fan 19 has a fan impeller 25. The diameter D of the fan impeller 25 is 80 mm.

[0147] The furnace tray system 1 is designed as a compact appliance and can therefore be easily and quickly inserted into the workspace 8 as a pre-assembled system. The furnace tray system 1, designed as a compact appliance, includes a housing 12, a furnace tray 2, and a flue gas extraction device 3, wherein the negative pressure duct 17 and fan 19 of the flue gas extraction device 3 are fully associated with the compact appliance, while the positive pressure duct 26 arranged downstream of the fan 19 is only partially associated with the compact appliance.

[0148] The operating modes of the cooking plate system 1, flue gas extraction device 3, cooking plate 2, and cooking item support 4 are as follows:

[0149] The heating plate system 1 is started via the user interface 9. User input for controlling the heating unit 5 and the fan 19 is transmitted to the control unit via the user interface 9. The control unit provides electrical power to operate the heating unit 5 and the fan 19. The status and performance data of the heating unit 5 and the fan 19 are transmitted to the user interface 9 via the control unit and are displayed visually via the user interface 9.

[0150] The heating unit 5 and the fan 19 can be powered independently of each other by means of a control unit. By activating the heating unit 5 located in the area of ​​the extraction section 22a, only the cooking item 6 located there is heated. By activating the fan 19 connected to the extraction section 22a, cooking steam is extracted via the inflow pipe 10 associated with the extraction section 22a.

[0151] The following is for reference. Figure 3 Another embodiment of the cooktop system 1 according to the present invention is described. Unlike the previous embodiment, the inflow pipes 10 are arranged in a non-uniformly distributed manner on the surface of the cooking item holder 4. Additionally, inflow pipes 10 are also arranged in the regions of the cooking zones 11. A negative pressure pipe 17 extends here, particularly between the heating unit 5 and the cooking item holder 4. For this purpose, the heating unit 5 is arranged spaced apart from the cooking item holder 4. The number of inflow pipes 10 per unit area in the edge regions of each cooking zone 11 is greater than the number of inflow pipes 10 per unit area in the central regions of each cooking zone 11, and greater than the number of inflow pipes 10 per unit area in the edge regions of the cooking item holder 4. The cross-sectional area of ​​the inflow pipes 10 varies depending on the position of each inflow pipe 10 relative to the cooking zone 11. The inflow pipes 10 arranged in the edge regions of the cooking zone 11 have a larger cross-sectional area than those in the central regions of the cooking zone 11 and in the edge regions of the cooking item holder 4.

[0152] The inflow pipe 10 is designed to allow both gas and liquid to pass through. A collection tray 27 for spilled liquid is arranged below the cooking item holder 4. In a top view, the collection tray 27 overlaps with multiple inflow pipes 10.

[0153] The cooking plate system 1 includes six cooking plates 2, each with a food support 4. The food supports 4 for the food to be cooked on each cooking plate 2 are formed separately from each other.

[0154] according to Figure 3The operating mode of the cooktop system 1 in the illustrated embodiment corresponds to the operating mode of the cooktop system 1 according to the above embodiment. Because the cooktop system 1 includes multiple cooktops 2 (each cooktop having only a single heating unit 5), the size of the support 4 for the food to be cooked is correspondingly smaller. Therefore, the support 4 for the food to be cooked can be removed from the individual cooking item support container 13 particularly easily and cleaned, especially in a dishwasher.

[0155] After removing the supports 4 for the food to be cooked from the individual cooking item support containers 13, the collection tray 27 can be easily cleaned from above. The filters 14 arranged on the individual cooking item supports 4 can be cleaned or replaced particularly easily.

[0156] Reference Figures 4 to 6 Another embodiment of the invention is described. Unlike the embodiments described above, the cooking item holder 4 has a single inflow pipe 10. A single inflow opening 18 for the flue gas extraction device 3 is formed on the upper side of the inflow pipe 10. The inflow opening 18 is covered by an inflow grille 28.

[0157] The cooktop system 1 includes a cooktop cover 29 for reversibly covering the cooking item holder 4 and the inlet opening 18. The cooktop cover 29 includes a cover body 30 that is displaceable relative to the cooking item holder 4. The cover body 30 can be positioned in a closed position and an open position. In a top view, the cover body 30 completely covers the cooking item holder 4 and the inlet opening 18 in the closed position. The cover body 30 includes a closure seal 31 for airtightly closing the inlet opening 18 in the closed position.

[0158] The cooktop cover 29 is hinged to the cooktop 2. In the open position, the cooktop cover 29 exposes the cooking item support 4 for heating the cooking items, especially the cooking zone 11, and the inlet opening 18 for extracting cooking steam.

[0159] The surface of the cooking dish holder 4 is arranged flush with the surface of the workspace 8. In the closed position, the cover 30 rests on the edge of the workspace 8. According to an alternative embodiment (not shown), the surface of the cooking dish holder 4 may be arranged below the surface of the workspace 8, and the surface of the cooktop cover 29 may be arranged flush with the surface of the workspace 8 in the closed position.

[0160] Figure 5A cross-section of the furnace system 1 is shown below. The flue gas extraction device 3 of the furnace system 1 includes four fans 19. Each fan 19 has a horizontally oriented axis of rotation 20. In the top view, the fans 19 are arranged equidistantly and equiangularly around a vertical axis extending through the center of the area of ​​the inflow opening 18. The axes of rotation 20 of every two adjacent fans 19 are oriented at a 90° angle to each other. The diameter D of the fan impeller 25 is 120 mm. The fans 19 are designed as axial fans.

[0161] The fan 19 is connected to the inlet opening 18 via a common negative pressure duct 17. The flue gas extraction device 3 includes a positive pressure duct 26 connected to the fan 19 in a flow guiding manner.

[0162] like Figure 6 As shown, the overall installation height H of the furnace tray system is 150 mm. A hollow cylindrical filter 14 is arranged downstream of the inlet opening 18, and the filter has a collection tray 17 for overflow liquid. The filter 14 is designed as a grease filter.

[0163] according to Figures 4 to 6 The operating mode of the cooktop system 1 in the illustrated embodiment corresponds to the operating mode of the cooktop system 1 according to the previous embodiment. The inflow grille 28 can be reversibly removed from the cooking item holder 4. The filter 14 can be removed from the inflow opening 18. The cooktop cover 29 can pivot between a closed position and an open position. The cooking item holder 4 is securely connected to the workspace 8.

[0164] refer to Figure 7 and 8 Another embodiment of the invention is described. Unlike the previous embodiment, the cooktop system 1 includes a cooktop 2 having four heating units 5 arranged side by side. The inlet opening 18 of the flue gas extraction device 3 has a rectangular outline and is located behind the heating units 5 or the cooking zone 11. The inlet opening 18 is in communication with four fans 19 via a negative pressure pipe 17, each fan having a fan impeller 25. The rotation axes 20 of the fan impellers 25 are parallel to each other and oriented horizontally.

[0165] The maximum front mounting height H in the horizontal area from the front edge 20a of the furnace system 1 to the geometric center SP v The height should be 120mm or less. Specifically, the installation height H of the furnace tray system 1... v Within this area, the installation height can be only within a range of 3cm to 5cm. In particular, the furnace plate system 1 has a low installation height from its front edge 20a at a depth T of at least 30cm, and especially at least 40cm. The overall height H of the furnace plate system 1 is 180mm or less.

[0166] The cooktop cover 29 has two covers 30. The two covers 30 can be arranged independently between an open position and a closed position. In the closed position, each cover 30 completely covers the two cooking zones 11 and partially covers the inlet opening 18.

[0167] Two covers 30 are attached to the furnace plate system 1 via a rotating mechanism 31a. The rotating mechanism 31a has a drive spring (not shown) and a damping element (also not shown). The rotating mechanism 31a ensures that the covers 30 are opened and closed smoothly and with damping during movement.

[0168] like Figure 8 As shown, the flue gas extraction device 3 includes two filters 14a and 14b arranged in a negative pressure duct 17. The first filter 14a, arranged downstream of the inlet opening 18 in the flow direction, is designed as a grease filter, and the second filter 14b is designed as an odor filter. In particular, an activated carbon filter is used as the odor filter. The second filter 14b may have one or more activated carbon elements. The activated carbon elements can be easily replaced. In particular, the activated carbon elements can be removed through the inlet opening 18.

[0169] As an alternative to or supplement to the second filter 14b in the negative pressure duct 17, an odor filter, particularly an odor filter in the form of activated carbon, may be arranged downstream of at least one fan 19. Specifically, a corresponding odor filter may be arranged downstream of each fan 19. These odor filters are preferably replaceable, and in particular, can be replaced without tools. Specifically, the odor filters can be removed from the positive pressure duct 26 via various removal openings.

[0170] The furnace plate cover 29 includes a closed cover 32 connected to the cover body 30 for airtightly closing the inflow opening 18. The cover body 30 and the closed cover 32 are spaced apart.

[0171] The operating mode of the cooktop system 1 corresponds to the operating mode of the cooktop system 1 according to the foregoing embodiment. Due to the relative displacement of the covers 30 relative to each other, the inflow opening 18 can be selectively left completely uncovered, partially covered, or completely covered. If the inflow opening 18 is partially covered, the extraction performance in the uncovered area of ​​the inflow opening 18 increases while keeping the performance of the fan 19 the same. The uncovered cooking zone 11 can still be used to heat the cooked food 6. The cooking zone 11 covered by the cover 30 automatically stops operating. For this purpose, the control unit is signal-connected to the contact switch 33 to detect the cover 30 in the closed position.

[0172] refer to Figure 9 and 10Another embodiment of the invention is described. Unlike the previous embodiment, the flue gas extraction device 3 includes two inflow openings 18 formed by two inflow pipes 10 passing through the cooking item support 4. The flue gas extraction device 3 also includes two guide elements 34, which are arranged adjacent to the inflow openings 18 and oriented parallel to the main extensions of the inflow openings 18. The guide elements 34 are each formed as a simply curved shell. The guide elements 34 are displaceable relative to the cooking item support 4 between a reset position and a guide position. In the guide position, each guide element 34 is at least partially arranged above the cooking item support 4. In the guide position, each guide element 34 shields the upper space upstream of each inflow opening 18 on the side with respect to the inflow opening 18. In the reset position, the upper side of each guide element 34 is arranged flush with the surface of the inflow opening 18 adjacent to the guide element 34.

[0173] The guide element 34 has a closing element 35. The closing element 35 is designed to cover each inflow opening 18 in the reset position.

[0174] like Figure 10 As shown, the furnace plate system 1 has sliding guide elements 36, which are used for the displacement of guide elements 34.

[0175] Figure 9 and 10 The operating mode of the cooktop system 1 shown corresponds to the operating mode of the cooktop system 1 according to the above embodiment. Displacement of each guide element 34 along the sliding guide element 36 causes the upper space to be shielded on one side, so as to directionally extract cooking steam in the guide position, and causes each inflow opening 18 to be closed in the reset position, thereby reliably preventing odors from escaping from the flue gas extraction device 3.

[0176] refer to Figure 11 and Figure 12 Another embodiment of the invention is described. Unlike the previous embodiment, the cooktop system 1 has a cooking dish support 4, three heating units 5, and a flue gas extraction device 3 with exactly one fan 19. The fan 19 of the flue gas extraction device 3 is designed as a radial fan. The fan 19 is in direct communication with the inflow opening 18 via an inflow duct 10.

[0177] The overall width B of the furnace tray system 1 is 560 mm. The overall height H of the furnace tray system 1, including the fan 19, is 180 mm. The depth T of the furnace tray system 1 is 515 mm.

[0178] The flue gas extraction device 3 includes a fan 19, wherein the furnace plate system 1 is designed as a combination appliance for one-piece installation in the workspace 8.

[0179] The inlet opening 18 of the fan 19 passes through the cooking item holder 4. In a top view, the inlet opening 18 is annular. The flue gas extraction device 3 has an inlet grille 28, which is reversibly arranged at the inlet opening 18. In a top view, the inlet grille 28 completely covers the inlet opening 18. The inlet grille 28 includes layered guide elements 34 arranged concentrically to support the layered extraction of cooking steam through the inlet grille 28 and the inlet opening 18.

[0180] The geometric center 37 of the inflow opening 18 is arranged to be spaced apart from the geometric center 38 of the cooking item holder 4. The distance 'a' between the geometric center 37 of the inflow opening 18 and the geometric center 38 of the cooking item holder 4 is... E It is 100mm. In the top view, along the width direction 39 and along the depth direction 40, the geometric center 37 of the inflow opening 18 is arranged to be spaced apart from the geometric center 38 of the cooking item support 4.

[0181] The minimum distance a between the geometric center 38 of the cooking item support 4 and the first heating unit 5 H1 The distance is 75mm, and the minimum distance a between the geometric center 38 of the cooking item support 4 and the second heating unit 5 is 1.5mm. H2 The minimum distance a between the inflow opening 18 and the first heating unit 5 is 10mm. EH1 Equal to the minimum distance a between the inflow opening 18 and the second heating unit 5 EH2 And equal to the minimum distance a between the inflow opening 18 and the third heating unit 5. EH3 The minimum distance a between the inlet opening and the heating unit 5 EH1 a EH2 a EH3 It is 40mm.

[0182] The cooking plate system 1 has a user interface 9. The user interface 9 includes a touch-sensitive surface 41 and multiple display elements 42. The user interface 9 is configured to control the heating unit 5 and the flue gas extraction device 3. In a top view, the user interface 9 is arranged opposite the inflow opening 18 to one of the heating units 5. In particular, the outer edges of the user interface 9 are arranged to be spaced apart from the geometric center 38 of the cooking item holder 4 along the width direction 39 and along the depth direction 40. The user interface 9 is located in the lateral edge region of the cooking item holder 4.

[0183] exist Figure 12The image shows a side view of the furnace plate system 1. The fan 19 includes a fan housing 43. The fan housing 43 is positioned above the lowest point of the inflow pipe 10. The distance between the lowest point of the inflow pipe 10 and the fan housing 43 is 50 mm. The fan housing 43 is positioned entirely below the heating element 5. This ensures a particularly compact design of the furnace plate system 1 in the horizontal direction.

[0184] The cooktop system 1 is at least partially housed within the kitchen base cabinet 42a. The cooktop system 1 extends through the workspace 8 supported on the kitchen base cabinet 42a. The width B of the kitchen base cabinet 42a is... K The depth T of the 42a kitchen base cabinet is 600mm. K Also 600mm. Kitchen base cabinet 42a has storage space 42b for accommodating the stovetop 1, as well as drawers or shelves. The storage space width B of kitchen base cabinet 42a... S It is 580mm.

[0185] The kitchen base cabinet 42a includes a heat insulation element 43a. The heat insulation element 43a is arranged on the kitchen base cabinet 42a such that it surrounds the bottom and front sides of the cooktop system 1. The heat insulation element 43a ensures reduced noise emissions and reduced heat input to the lower area of ​​the kitchen base cabinet 42a.

[0186] The operating mode of the furnace plate system 1 according to this embodiment corresponds to the operating mode of the furnace plate system 1 described above.

[0187] Figure 13 Another embodiment of the furnace tray system 1 is shown. Unlike the furnace tray system 1 described above, the starting portion 44 of the inflow pipe 10 has a central longitudinal axis 45 that is oriented at an angle relative to the furnace tray normal 46. The angle between the central longitudinal axis 45 of the starting portion 44 and the furnace tray normal 46 is 45°.

[0188] The cross-section of the starting portion 44 is annular. Due to the inclined orientation of the central longitudinal axis 45 relative to the furnace plate normal 46, the inflow opening 18 is elliptical.

[0189] Because the overall width B of the cooktop system 1 is at most 600 mm, and especially 560 mm, it is possible, for the first time, to arrange the cooktop system 1 with the flue gas extraction device 3 in a kitchen base cabinet 42a that is particularly small. This advantageously allows the cooktop system 1 to be used in a particularly flexible manner and therefore to be installed in a fairly wide range. The design of the cooktop system 1 with a maximum installation height of 200 mm is particularly advantageous because the storage space 42b is kept to its maximum possible size to accommodate, for example, kitchen utensils.

[0190] Figure 14 and 15Another embodiment of the hearth system 1 is shown. Unlike the hearth system 1 described above, the flue gas extraction device 3 includes two fans 19, each fan having a fan impeller 25 rotatably mounted about a rotation axis 20, wherein the rotation axis 20 is oriented at an angle relative to the horizontal plane and the vertical direction, respectively. In the top view, the hearth system 1 includes four rectangular heating units 5. The heating units 5 and the flue gas extraction device 3 are signal-communicated with the user interface 9.

[0191] The flue gas extraction device 3 has an inflow opening 18 centrally located at the cooking item support 4. The starting portion 44 of the negative pressure pipe 17 is connected to the inflow opening 18.

[0192] Fan 19 has a fan housing 43. Fan housing 43 includes a negative pressure connection opening 47. Starting portion 44 passes through negative pressure connection opening 47. Pipe connection 48 connects starting portion 44 to fan housing 43 in a fluid-tight manner.

[0193] The connecting normal 49 is perpendicular to the negative pressure connection opening 47. The connecting normal 49 and the rotation axis 20 form a connecting angle α of 80°.

[0194] Power electronic components 50 for supplying power to heating units 5 are mounted below each heating unit 5. By tilting the rotation axis 20, space is provided in the area between each heating unit 5 and the fan 19 for the power electronic components 15, especially for individual components of the power electronic components 15 that require a large amount of installation space.

[0195] In the top and side views, the two fans 19 overlap with the heating unit 5. Thus, the furnace plate system 1 is configured in a particularly compact manner. The overall installation height H is 180 mm.

[0196] The suction direction 51 of fan 19 has a vertically upward component. The suction direction 51 is oriented parallel to the rotation axis 20. Because the suction direction 51 has an upward component, it reliably protects fan 19 from liquid ingress.
