Extractor hood for a food preparation appliance, use and system

Description

[0001] The invention relates to a fume extraction device for a food preparation appliance, a use of a fume extraction device and a food preparation system.

[0002] When preparing food with a food preparation appliance, such as a food processor, fumes are often released. This is especially true during cooking processes. Fumes refer to air containing steam, grease, and / or odors. Such odors are often undesirable, at least in living areas. The moisture contained in the fumes can also lead to unwanted condensation, for example, on kitchen cabinets. Therefore, there is a need to filter the fumes produced by food preparation appliances.

[0003] One solution is to place a food preparation appliance on a cooktop to utilize a conventional range hood permanently installed above the cooktop. However, a cooktop is not a suitable surface for a food preparation appliance, as residual heat from the cooktop or accidental activation of a burner poses a risk of damage or fire. Furthermore, the cooktop would be blocked and therefore unusable. Conventional range hoods also require high extraction power due to the significant distance from the source of the fumes, resulting in noise and high energy consumption. Devices that extract fumes downwards from a lower position are often incompatible with food preparation appliances due to their height.

[0004] Documents EP 3 377 821 B1, EP 3 513 127 B1 and US 2012 / 204 855 A1 disclose devices for heating food with a hot plate, which are also equipped for fume extraction. Documents FR 2 761 620 A1, EP 3 211 325 A1, JP 2000 018 601 A and JP S54 68 464 U describe fume extraction devices.

[0005] The object of the invention is to provide an improved extractor fan for a food preparation appliance, a use of an extractor fan and a system with which at least some of the above-mentioned disadvantages are eliminated.

[0006] The problem is solved by a fume extraction device according to claim 1, as well as by the use of a fume extraction device and a system according to the dependent claims. Advantageous embodiments are specified in the subclaims.

[0007] To solve the problem, a fume extraction device for a food preparation appliance is provided. The fume extraction device comprises a housing with an intake opening, a filter arranged within the housing, and a suction mechanism that draws fumes from the food preparation process through the intake opening and conveys them through the filter. The fume extraction device also includes a base for placing the food preparation appliance.

[0008] The solution according to the invention is a fume extraction device for use with a food preparation appliance. This device filters the fumes produced during food preparation using the appliance. In this way, the release of steam and odors is reduced. The use of a conventional extractor hood is not necessary. The installation surface allows the food preparation appliance to be placed in a predefined position, so that the distance between the food preparation appliance and the extraction system is significantly reduced compared to a conventional extractor hood. This reduces noise emissions and saves energy. The distance is also defined, allowing the extraction system to be optimized for this distance. Furthermore, the solution according to the invention is not location-dependent and can therefore be used flexibly in different locations.

[0009] A food preparation appliance is a device used to prepare food. According to the invention, the food preparation appliance is a food processor. The food processor is designed for food preparation by chopping, stirring, and / or heating. The food preparation appliance is a portable device that can be placed in any position, for example, on a kitchen work surface.

[0010] The housing serves to contain the filter and / or the suction unit. The filter and / or the suction unit are, in particular, at least partially located or can be located within the housing. Alternatively, the suction unit can also be located on the outside of the housing. The housing is a protective shell for the filter and, if applicable, the suction unit. The housing can therefore be made of a rigid material such as metal and / or plastic. The housing contains a suction opening for drawing the fumes into the interior. The buttons can be configured so that raising or lowering only occurs while the respective button is pressed (also known as a long press). This allows for precise manual adjustment to the desired height. Alternatively, the buttons can be configured so that raising or lowering...Lowering is activated by a single press of the corresponding button, and then the device automatically moves to a preset position, specifically a working position or a retracted position (also known as a short press). If multiple working positions are available, a second press of the button may be necessary. This allows for simple and user-friendly adjustment of the desired height.

[0011] In one embodiment, the housing comprises two parts, each of which can be moved downwards from its operating position and lowered into the cabinet independently of the other part, and then raised again from its lowered position. Typically, the housing is divided by a vertical gap. Preferably, each of the two parts has an intake opening. Typically, each intake opening is located in the upper region of its respective part. In particular, the two parts are arranged side by side. Typically, the two parts are directly adjacent, so that there is no significant gap between them. This design allows several kitchen appliances to be placed side by side on the work surface to perform multiple food preparation processes simultaneously.For example, a food processor and another food preparation appliance such as a grill or a waffle iron can be operated simultaneously.

[0012] In particular, each of the two parts can be positioned at different heights. This allows for adjustments to accommodate different appliance heights, ensuring that fumes from each appliance are extracted close to their source. Furthermore, the amount of fumes drawn through the intake opening of each part is individually adjustable. This allows for different suction power levels to be achieved simultaneously for different food preparation processes.

[0013] The extractor hood is designed to adjust a parameter of the suction unit based on control commands from a controller. In one embodiment, the extractor hood is designed to control the lifting and lowering mechanism based on control commands from a controller. Typically, the controller sends control commands to the lifting and lowering mechanism or the suction unit, allowing the height position of an intake opening and / or a parameter of the suction unit to be set. The parameter of the suction unit could be, for example, a rotational speed, a motor current, and / or a volume flow rate to be drawn in.

[0014] The extractor hood can include its control unit. Alternatively, the extractor hood is designed to communicate with an external control unit for this purpose. The external control unit could be, for example, a data processing unit of a portable electronic device, such as a smartphone or tablet, or of the food preparation appliance itself. In the case of an external control unit, the extractor hood typically includes an interface for receiving signals from the control unit. This interface can be configured to receive data via Bluetooth, Wi-Fi, radio frequency, and / or the internet.

[0015] In one embodiment, the extractor hood includes an input device for entering the parameter and / or controlling the extraction unit. For example, the input device may be at least one switch and / or at least its button. For example, the input device may be similar to that of a conventional extractor hood. In another embodiment, the extractor hood includes an output device with which information can be output to the user. The information may include at least one parameter and / or a prompt for input and / or a confirmation. The input device and the output device may be combined as an input and output device, for example, in a touch-sensitive display.

[0016] In one embodiment, the extractor hood has a sensor for measuring a property of the fumes from food preparation, and the control system is configured to regulate the suction power of the extraction unit based on this measured property. Suction power refers to the power that the motor of the extraction unit uses to move the fumes. This correlates with the volume flow rate. For example, the humidity of the fumes can be measured, and at high humidity, the extraction unit can be automatically controlled to draw in a larger volume flow. Alternatively or additionally, the water vapor or particle content in the fumes can be measured to control the extraction unit accordingly. The measurement of a property of the fumes can be performed externally on the housing, e.g., in the area of ​​an intake opening, or inside a flow channel within the housing. This enables control and / or adjustment of the extraction unit.The system controls the extractor fan and can thus ensure a quality of the filtered fumes with minimal effort, while minimizing energy consumption and noise levels.

[0017] In one embodiment, the extractor hood has a sensor for determining the height of the food preparation appliance, and the control system is configured to control the lifting and lowering mechanism based on this sensor information. This information can be, for example, the overall height of the food preparation appliance, the type of food preparation appliance, or the presence of an optional accessory. The sensor can be, for example, an optical or ultrasonic sensor. The extractor hood's control system is configured to set a suitable height based on the sensor information. This can be achieved by pre-setting different heights that are selected based on the sensor's readings, or by directly deriving or calculating a height from the sensor's readings.

[0018] According to the invention, the extractor hood is configured to establish a data connection with the food preparation appliance, enabling the control system to access information from the food preparation appliance and to adjust the suction device parameters based on this information. In one embodiment, the lifting and lowering mechanism is controlled based on this information. The information can include data from the food preparation appliance and / or the food preparation process.

[0019] The data connection is established, in particular, with the food preparation appliance located on the installation surface. The data connection is, in particular, a wireless connection, for example, via Bluetooth, WiFi, radio, and / or the internet. However, a wired connection is not excluded. In this way, the control system can receive information from the food preparation appliance and / or the installation surface. The width of the installation surface is typically greater than 10 cm, in particular greater than 15 cm, and preferably greater than 20 cm, and / or less than 40 cm, typically less than 35 cm, and in particular less than 30 cm. In the second case, the width of the installation surface is typically greater than 30 cm, in particular greater than 35 cm, and preferably greater than 40 cm, and / or in particular less than 65 cm, and preferably less than 55 cm.

[0020] In one embodiment, the mounting surface is essentially flat. The mounting surface is typically horizontally oriented. It may have a non-slip surface, for example made of plastic or rubber.

[0021] In one embodiment, the horizontally measured distance, e.g., viewed from above, between the center point of the installation surface and the intake opening is less than 25 cm, preferably less than 20 cm, and / or greater than 5 cm, particularly greater than 10 cm. The center point is the point located in the middle of the installation surface, in particular the centroid of the installation surface. In another embodiment, the horizontally measured distance between the installation surface and the intake opening is less than 15 cm, particularly less than 10 cm, preferably less than 5 cm. This shorter path reduces the amount of fumes generated by the suction device and thus the noise level, ensuring particularly energy-efficient operation.

[0022] In one embodiment, the vertically measured distance, e.g., as seen from the side, between the installation surface and the intake opening is not less than 20 cm and / or not greater than 60 cm. This refers to the distance between the top edge of the installation surface on which the food preparation appliance is placed and the highest or lowest point of the intake opening. Specifically, this distance is not less than 25 cm or 30 cm and / or not greater than 50 cm or 45 cm. These distances refer to a usage position described below.

[0023] The distance is at least 20 cm to ensure that the fumes are drawn in at approximately the same height at which they exit the food preparation appliance. This reduces the amount of fumes and noise, ensuring energy-efficient operation. The distance is not excessively large to limit the housing's height, allowing for installation on a kitchen worktop under wall cabinets.

[0024] In one embodiment, the housing has a height between 45 cm and 60 cm. The height is measured specifically between a base for placement on a work surface and the highest point of the housing. The suction opening can extend to the top of the housing or just below it. This keeps the overall height low while simultaneously achieving particularly efficient suction.

[0025] In one embodiment, the housing and the part of the extractor hood comprising the mounting surface are manufactured as a single piece, permanently connected to each other, or permanently connectable to each other. This provides a stable unit and prevents incorrect operation. With a permanent connection, the extractor hood is designed in two parts, with the housing being the first part and the second part comprising the mounting surface.

[0026] In one embodiment, the housing includes at least one externally accessible storage compartment for storing items, and in particular, a closure for closing the storage compartment. The storage compartment can be used for storing accessories. The closure can be a flap. Alternatively or additionally, the storage compartment can be a drawer, with the drawer's front wall forming the closure when closed.

[0027] In particular, the storage space is accessible from a side wall of the housing, so that access to the storage space is possible even when a food preparation appliance is placed on the installation surface. In one embodiment, one or more storage spaces are provided on each side.

[0028] In one embodiment, the extractor hood has a base for placement on a work surface. The extractor hood is thus designed so that its base can be placed, for example, on a kitchen work surface or a table. The base can be a substantially flat surface and / or have feet, which may be made of rubber. In particular, the base of the housing and, if applicable, the base are arranged in the same plane, allowing for stable placement. The part of the extractor hood comprising the base can have a height of less than 5 cm, in particular less than 3 cm, and preferably less than 2 cm or 1 cm.

[0029] In one embodiment, the extractor hood includes a cabinet beneath the installation surface. Specifically, the cabinet contains several storage compartments accessible from the outside. These storage compartments are designed as drawers. The cabinet is not merely positioned below the installation surface, i.e., at a lower height than the surface, but rather directly beneath it, so that the food preparation appliance rests indirectly on the cabinet during normal use. The cabinet is also typically located beneath the housing.

[0030] In one embodiment, the cabinet is mobile. In other words, the cabinet has casters or wheels so that it can be moved. In particular, the cabinet also has a locking device so that it can be locked in the desired position. The cabinet can have a height greater than 70 cm, in particular greater than 80 cm, and / or less than 105 cm, in particular less than 95 cm.

[0031] In one embodiment, the extractor hood comprises a hinged worktop element that can be pivoted from a space-saving storage position to a horizontal working position and back again. The positions refer to the surface of the worktop element. Several worktop elements, for example two, may be present. In particular, at least one worktop element is arranged laterally. In one embodiment, a worktop element is present on each side. The storage position can be essentially vertical. A fastening mechanism is provided, in particular, to secure the worktop element in the storage position and / or in the working position.

[0032] In one embodiment, the extractor hood has a lifting and lowering mechanism with which at least a portion of the housing can be moved up and down to adjust different height positions. Specifically, the housing portion can be moved downwards from a usable position and lowered, and then moved back up from the lowered position. The movable portion preferably includes the intake opening and, in particular, also the filter and / or the suction device. The lifting and lowering mechanism typically comprises an electric motor for driving a mechanism and the mechanism itself, with which at least a portion of the housing can be moved. Specifically, a portion of the housing can be moved into or lowered into another portion of the housing. Lowering means at least partial, and in particular complete, lowering of the housing portion.

[0033] There is at least one operating position in which the extractor fan is configured to draw in and filter fumes from food preparation. Specifically, in this operating position, an intake opening is positioned at a height close to the top of the food preparation appliance. There may also be a recessed position in which the extractor fan housing is stowed away to save space. In the recessed position, the extractor fan is typically not intended for use. An intake opening for the extractor fan is typically located in the upper part of the retractable section of the housing.

[0034] This allows the housing to be easily stored in a space-saving manner and protected from dirt when not in use. The cabinet can be used like a conventional cabinet, possibly on wheels. In particular, the extractor hood is designed so that a worktop is available when it is lowered. The corresponding part of the housing can have the worktop on its upper surface.

[0035] In one embodiment, several operating positions are specified, in which the housing of the extractor fan, and thus the intake opening, is arranged at different heights. In this way, the height of the intake opening can be adjusted, for example, to whether the food preparation appliance is used with an accessory that is placed on top of a food preparation container of the appliance, or not. Such an accessory could, for example, be a steamer attachment. If such an accessory is present, the fumes from the food preparation escape into the surrounding area at a higher position and can consequently be extracted from a higher position.

[0036] In one embodiment, the extractor hood includes an input device for receiving a command to activate the lifting and lowering mechanism for raising or lowering the housing. For example, the input device may consist of two buttons, one lowering the housing and the other raising it. The buttons may be configured so that raising or lowering occurs only while the respective button is pressed (also known as a long press). This allows for precise manual adjustment to the desired height. Alternatively, the buttons may be configured so that raising or lowering is activated by a single press of the corresponding button, after which the unit automatically moves to a preset position, in particular to a working position or a retracted position (also known as a short press).If multiple operating positions are available, a second press of the button may be necessary. This allows for easy and user-friendly adjustment of the desired height.

[0037] In one embodiment, the housing comprises two parts, each of which can be moved downwards from its operating position and lowered into the cabinet independently of the other part, and then raised again from its lowered position. Typically, the housing is divided by a vertical gap. Preferably, each of the two parts has an intake opening. Typically, each intake opening is located in the upper region of its respective part. In particular, the two parts are arranged side by side. Typically, the two parts are directly adjacent, so that there is no significant gap between them. This design allows several kitchen appliances to be placed side by side on the work surface to perform multiple food preparation processes simultaneously.For example, a food processor and another food preparation appliance such as a grill or a waffle iron can be operated simultaneously.

[0038] In particular, each of the two parts can be positioned at different heights. This allows for adjustments to accommodate different appliance heights, ensuring that fumes from each appliance are extracted close to their source. Furthermore, the amount of fumes drawn through the intake opening of each part is individually adjustable. This allows for different suction power levels to be achieved simultaneously for different food preparation processes.

[0039] The extractor fan is designed to adjust a parameter of the suction device based on control commands from a controller.

[0040] In one embodiment, the extractor hood is configured to control the lifting and lowering mechanism based on control commands from the controller. Typically, the controller sends control commands to the lifting and lowering mechanism or the suction unit, allowing the height position of an intake opening and / or a parameter of the suction unit to be set. The parameter of the suction unit could be, for example, a rotational speed, a motor current, and / or a volume flow rate to be drawn in.

[0041] The extractor hood can include its control unit. Alternatively, the extractor hood is designed to communicate with an external control unit for this purpose. The external control unit could be, for example, a data processing unit of a portable electronic device, such as a smartphone or tablet, or of the food preparation appliance itself. In the case of an external control unit, the extractor hood typically includes an interface for receiving signals from the control unit. This interface can be configured to receive data via Bluetooth, Wi-Fi, radio frequency, and / or the internet.

[0042] In one embodiment, the extractor hood includes an input device for entering the parameter and / or controlling the extraction unit. For example, the input device may be at least one switch and / or at least its button. For example, the input device may be similar to that of a conventional extractor hood. In another embodiment, the extractor hood includes an output device with which information can be output to the user. The information may include at least one parameter and / or a prompt for input and / or a confirmation. The input device and the output device may be combined as an input and output device, for example, in a touch-sensitive display.

[0043] In one embodiment, the extractor hood has a sensor for measuring a property of the fumes from food preparation, and the control system is configured to regulate the suction power of the extraction unit based on this measured property. Suction power refers to the power that the motor of the extraction unit uses to move the fumes. This correlates with the volume flow rate. For example, the humidity of the fumes can be measured, and at high humidity, the extraction unit can be automatically controlled to draw in a larger volume flow. Alternatively or additionally, the water vapor or particle content in the fumes can be measured to control the extraction unit accordingly. The measurement of a property of the fumes can be performed externally on the housing, e.g., in the area of ​​an intake opening, or inside a flow channel within the housing. This enables control and / or adjustment of the extraction unit.The system controls the extractor fan and can thus ensure a quality of the filtered fumes with minimal effort, while minimizing energy consumption and noise levels.

[0044] In one embodiment, the extractor hood has a sensor for determining the height of the food preparation appliance, and the control system is configured to control the lifting and lowering mechanism based on this sensor information. This information can be, for example, the overall height of the food preparation appliance, the type of food preparation appliance, or the presence of an optional accessory. The sensor can be, for example, an optical or ultrasonic sensor. The extractor hood's control system is configured to set a suitable height based on the sensor information. This can be achieved by pre-setting different heights that are selected based on the sensor's readings, or by directly deriving or calculating a height from the sensor's readings.

[0045] The extractor hood is configured to establish a data connection with the food preparation appliance, allowing the control system to access information from the appliance and adjust the extraction unit's parameters based on this information. This information can include data from the food preparation appliance and / or the food preparation process. In one embodiment, the lifting and lowering mechanism can also be controlled based on this information.

[0046] The data connection is established primarily with the food preparation appliance located on the installation surface. This connection is typically wireless, for example via Bluetooth, Wi-Fi, radio, and / or the internet. However, a wired connection is not excluded. This allows the control unit to access information from the food preparation appliance and / or the food preparation process. The control unit can be located within the extractor hood or the food preparation appliance itself.

[0047] In particular, the food preparation appliance is designed to prepare a dish, at least semi-automatically, using an electronically stored recipe. The recipe may include commands for controlling the height and / or the suction device. Alternatively or additionally, the control system can derive information about a required height and / or a parameter of the suction device from the recipe. This can be done, for example, by inferring the presence of a corresponding accessory from the recipe step "steam cooking" and / or the need for particularly strong suction power from the recipe step "sautéing onions".

[0048] In one embodiment, the control system is configured to access different profiles, with each profile containing parameters of the suction unit and / or information for controlling the lifting and lowering mechanism. This allows the suction unit parameters to be set or the lifting and lowering mechanism to be controlled based on a profile. A profile refers specifically to a digitally stored profile. Each profile can contain information on height positions and / or suction unit parameters, such as suction power. The profiles can be stored in the extractor hood, in the control unit, or externally. If the profile storage location is physically separate from the control unit, a data connection between the control unit and the external storage location exists or can be established. Such a data connection can be established, for example, via Bluetooth, Wi-Fi, radio, and / or the internet.The control system is designed to automatically adjust the height and / or parameters of the suction device as defined in the profile. Such an adjustment can be triggered, for example, by user input or automated user recognition. User input can be made, for instance, via an input device on the extractor hood, a portable electronic device, or an input device on the food preparation appliance.

[0049] In one embodiment, at least one, and in particular several, electrical outlets for connecting the food preparation appliance and, if applicable, other kitchen appliances are arranged on the top of the cabinet. Specifically, the electrical outlet is located on the top or on a power strip situated on the top. The cabinet may have a connecting cable with a plug for electrical connection to an outlet near the extractor fan.

[0050] In one embodiment, at least one lighting device is arranged on the housing. The lighting device is designed, in particular, to illuminate the installation surface and, if applicable, a food preparation appliance placed on the installation surface. Additionally or alternatively, a worktop and / or a worktop element of the extractor hood can also be illuminated by the lighting device. In one embodiment, a brightness sensor is provided, and the lighting device can be automatically controlled based on the detected brightness.

[0051] In one embodiment, the extractor hood includes at least one camera with which a user of the extractor hood and / or the food preparation appliance can be photographed and / or filmed during food preparation. In this way, photos can be taken and video conferences can be held during food preparation. For example, cooking together digitally is possible.

[0052] In one embodiment, the extractor fan includes at least one camera with which the food preparation process can be photographed and / or filmed. In this way, the food preparation can be documented.

[0053] In one embodiment, the extractor hood includes a holder for a portable electronic device, such as a smartphone and / or tablet. This simplifies the use of electronic devices during food preparation. For example, it allows access to a digital recipe platform, video platforms, and / or other entertainment services, and / or enables video conferencing.

[0054] In one embodiment, the extractor hood includes a data interface that allows data from at least one camera to be sent to a portable electronic device and / or the camera to be controlled via the portable electronic device. In this way, a video conference can be conducted using a camera integrated into the extractor hood.

[0055] Another aspect of the invention is the use of an extractor hood according to the invention with a food preparation appliance for food preparation, wherein the food preparation appliance is placed on the installation surface of the extractor hood, particularly during food preparation.

[0056] Another aspect of the invention is a food preparation system with an extractor hood according to the invention and a food preparation appliance, wherein the extractor hood and the food preparation appliance are designed in such a way that the food preparation appliance can be placed on the installation surface of the extractor hood.

[0057] Another aspect of the invention relates to a system comprising the extractor hood according to the invention and an external control unit, wherein the extractor hood is configured to adjust a parameter of the suction device and / or to control the lifting and lowering mechanism based on control commands from the external control unit. The external control unit can be, for example, a data processing unit of a portable electronic device, such as a smartphone or tablet, or of a food preparation appliance.

[0058] Another aspect of the invention relates to a method for food preparation using a food preparation appliance and a fume extraction device according to the invention, wherein food is prepared in the food preparation appliance, and the fumes generated during food preparation are extracted and filtered by means of the fume extraction device. All features, embodiments, and effects of the device described above also apply to the independently described aspects of the use, the systems, and the method, and vice versa.

[0059] Exemplary embodiments of the invention are explained in more detail below, also with reference to figures. Features of the exemplary embodiments can be combined individually or in multiples with the claimed subject matter, unless otherwise specified. The claimed scope of protection is not limited to the exemplary embodiments.

[0060] They show: Figure 1: a schematic representation of a range hood, Figure 2: a food processor, Figure 3: a schematic front view of a range hood, and Figure 4: a schematic side view of a range hood.

[0061] Figure 1Figure 1 shows a side view of a fume extraction device 1 according to the invention. The drawing is not to scale, so sizes and proportions do not necessarily correspond to reality. A filter 4 and a suction device 5 are arranged in a rectangular housing 3 with an intake opening 6. The suction device 5 can generate a fume stream to draw fumes from food preparation using a food preparation appliance 2 through the intake opening 6. The fume stream passes through a flow channel through the housing 3. At least one filter 4 is arranged in the flow channel to remove substances from the fumes. An outlet opening 32 is also provided in a side wall of the housing 3, through which the filtered fumes can leave the housing 3. In the example shown here, the suction device 5 is located in the housing 3 behind the outlet opening 32.The extractor hood 1 comprises a flat underside 24 for placement on a kitchen work surface. The underside 24 is formed jointly by the part forming the mounting surface 20 and the underside of the housing 3.

[0062] Furthermore, the extractor hood 1 comprises a mounting surface 20 on which a food preparation appliance 2 is placed. The mounting surface 20 is located on the top of a part of the extractor hood 1 that is either permanently connected to the housing 3 or manufactured as a single piece, and which, together with the housing 3, forms an L-shape in the example shown here.

[0063] The mounting surface 20 is flat and has a depth B2 between 20 cm and 40 cm. The depth B2 extends, for example, over the entire depth of the part containing the mounting surface 20. Alternatively, it can also be less than this part, for instance, if the part has a front and / or rear edge. A horizontally measured distance A1 between the center of the mounting surface 20 and the intake opening 6 is between 10 cm and 25 cm. A vertically measured distance A2 between the surface of the mounting surface 20 and the lowest point of the intake opening 6 is between 30 cm and 45 cm. A vertically measured distance between the surface of the mounting surface 20 and the highest point of the intake opening 6 is between 45 cm and 55 cm.

[0064] Food preparation appliance 2 is a food processor 7. This includes a steaming attachment 22, which is placed on a food preparation container of the food processor 7. The height H1 of the food processor 7 without the attachment 22 is 34 cm. The height H2 of the food processor 7 with the attachment 22 is 44 cm. During steaming, steam is released from the top of the attachment 22. During food preparation without the attachment 22, steam is released from the top of the food preparation container. The intake opening 6 is located near the point where steam is generated in both cases.

[0065] The Figure 2Figure 1 shows a food processor 7 with a food preparation bowl 8. A lid 9 is placed on the food preparation bowl 8. The lid 9 for the food preparation bowl 8 is locked by arms 10. The lid 9 is located between the two arms 10. The arms 10 can be rotated between an open position and a locked position. The lid 9 has a sensor, specifically a toggle lever 11 of an electrical switch, which is pressed down and thus triggered. The arms 10 and the toggle lever 11 are attached to a base 12 of the food processor 7. The food preparation bowl 8 is inserted into the base 12 and can be removed from it. To facilitate removal, the food preparation bowl 8 includes a handle 13. The base 12 includes a touch-sensitive display 14 and a rotary switch 15 for operation. The rotary switch 15 can be rotated and pressed.Display 14 and rotary switch 15 are therefore the operating elements of the food processor 7. Control commands and / or data can be entered via the operating elements 14 and 15. The lid part 9 has a central opening 16, which can be closed with a fastener (not shown). The base 12 can be placed on the work surface.

[0066] The base unit 12 contains a control unit 17. This can be the controller 21 for controlling the extraction unit or communicate with it. The control unit 17 can therefore control the operation of the extractor hood 1. The base unit 12 contains a radio unit 18, which allows data to be sent and received wirelessly. The radio unit 18 can, for example, send and receive data via Bluetooth and / or WiFi. The control unit 17 can access, for example, an externally stored electronic recipe via the radio unit 18. The control unit 17 can then use the recipe to control the preparation of a dish. The control unit 17 can also exchange data wirelessly with the extractor hood 1 via the radio unit 18. Data can be exchanged with the control unit of the extractor hood 1 via the radio unit 18.Recipes can alternatively or additionally be stored in a storage unit of the control device.

[0067] The food preparation vessel 8 contains a stirring and / or cutting tool that can be driven by a motor. The motor is located in the base 12.
