Description

Hob and preparation vessel for food and preparation device comprising this

description

The invention relates to a hob and a preparation vessel and a preparation device for foodstuffs comprising the same.

Preparation devices, such as, for example, food processors or multifunctional cooking devices, which were conventionally also referred to for simplicity as kitchen machines, are of increasing importance due to the preparation processes that are possible with them, which are even partially automated. In general, these devices are intended to cover a partially automated or automated preparation, processing or preparation of food up to a fully automated preparation of meals.

The integration of menu-driven user guidance and access to recipe databases, especially non-local recipe databases, allow even inexperienced users to prepare a large number of different and usually sophisticated dishes.

Many of these preparation devices also have sensory functions, such as temperature detection or weighing devices, which further simplify the respective preparation and can make the preparation process itself more reliable. An exemplary preparation device with a preparation vessel and a base station is described in DE 102016 116 975 A1. The preparation vessel described there is intended to be operated together with its base station in the kitchen area. However, its manufacturer warns against placing it near cooking equipment, such as hobs, in order to avoid damage to the preparation device and, in particular, to its base station.

As advantageous as such devices can be for the respective user, the associated space requirement is also noticeable.

Furthermore, the release of fluids, such as water, oil or fat vapors, that occur during cooking processes can not only be unpleasant for the user, but also be detrimental to their health in the long term.

These water, oil and grease vapors can be particularly harmful to kitchen overhead cabinets, which often consist of easily swellable wood or at least include it.

Cooking processes are often carried out without a splash guard, which means that there is a risk of walls and other kitchen equipment in the vicinity being soiled.

If a splash guard is used, it must be purchased separately, as such Splash protection devices are not part of conventional kitchens or kitchen equipment.

Open or unprotected current-carrying cables can occur as dangerous facts, which migrate or fall down when stirring or kneading with appropriate stirring or kneading devices and can lead to injuries and damage.

Previously, hobs and kitchen machines, such as food processors, had different user guidance, which was usually accompanied by two different operating units, different operating logic and each with its own database.

Because of the risk of breakage, kitchen appliances such as food processors, for example, were not allowed to stand on hobs because of their weight, and thus generally not under a fume cupboard associated with the hob, for example.

These kitchen machines were regularly very noisy and, as a separate device, were not provided with their own sound-absorbing enclosure.

The invention is based on the object of at least alleviating the disadvantages mentioned above.

This object is achieved with the subject matter of independent claims 1, 22 and 28. Preferred developments are the subject matter of the further claims as well as the description and the figures.

The invention discloses a hob with a receptacle for a preparation vessel and at least one

Functional device, the preparation vessel having a stirring and / or chopping and / or cutting device, in particular a device for comminuting.

In the context of the present disclosure, a receptacle is understood to be a device which is at least suitable for forming a stand for the preparation vessel assigned to the receptacle in each case. Further advantageous properties and configurations of the presently disclosed receptacle are described in more detail below.

The functional device is preferably a functional device of a base station of a preparation device, in particular a food processor, which is assigned to a functional device of the preparation vessel.

Insofar as these further functional devices are linguistically assigned to the receptacle in the context of the present disclosure, or are referred to as functional devices of the receptacle, they can nevertheless be designed as assemblies of the hob and physically arranged in it and in particular with data technology as well as electrical and electronic Assemblies of the hob supplied and electrically connected to them.

In the context of the present disclosure, the term hob includes a device, in particular with a hob plate, on which cooking vessels can be placed and with which these cooking vessels and / or their contents can be heated. The term “hob” thus also includes heating devices typically arranged under the hob plate, such as, for example, inductive and / or heat radiation emitting heating devices and their electrical and electronic devices

Supply facilities, the detailed design of which will be disclosed in more detail at a later point.

Heating devices arranged on the preparation vessel can in particular comprise resistance heating devices, preferably thick-film resistance heating devices.

For the purposes of the following description, the term “food” should also include pre-products of food, unless explicitly stated in each case.

Preliminary products can be products which can be converted into food through appropriate measures, such as green tomatoes when they are heated or kale when they are cooled below freezing point. For the purposes of the present disclosure, a preparation vessel comprises a vessel with a space for holding food or its preliminary products, which can be designed to be closable, and is suitable and intended for the preparation of food, in particular food intended for human consumption.

Embodiments of conventional preparation devices are known to the person skilled in the art and can also be purchased in a variety of ways. Cooking functions could already be realized with these conventional preparation vessels and the preparation vessels disclosed here can be used for cooking, in particular cooking or frying, preferably also in parallel to a corresponding use of the hobs disclosed here.

The food processors are conventional preparation devices such as the Thermomix device from Vorwerk, the Food Processor 5KSM2FPA from Kitchen-Aid, the Phillips-HR762, the Prep & Cook device from Krupps, the Cookit device from Bosch, Monsieur Cuisine from Silvercrest, the food processor with cooking function MD 16361 available for purchase from Medion.

The hob disclosed in the present case forms a surface facing the user on the upper side, in which the receptacle is arranged, a hob plate of the hob preferably and advantageously consisting of glass or glass ceramic or at least comprising glass or glass ceramic and preferably this surface of the upper side as a work area Provides. The hob plate can also consist of or comprise other temperature-resistant materials such as mineral panels, fine tile panels such as TPB.

In the case of this hob, a recess for receiving, in particular, a lower part of the preparation vessel is formed in the surface of the top side.

This recess is advantageously designed as a trough. However, the recess can also comprise an opening in the hob plate.

Particularly preferably, the receptacle comprises, as a functional device, a mechanical coupling device for coupling, in particular a device for rotationally fixed coupling with an associated mechanical coupling device as a functional device of an associated preparation vessel.

In a further embodiment, the receptacle has, in particular as a functional device, a weighing device, in particular for weighing the preparation vessel with or without food or pre-products of food arranged therein. This functional unit does not have to be assigned an independent functional unit of the preparation vessel, since it can independently detect the weight of the preparation vessel and of the preparation vessel with the foodstuffs arranged therein. In particular, transmitters for electrical energy, in particular in the form of contact pins or coupling parts, can be arranged in or on the receptacle.

Here, alternatively or additionally, transformers for electrical energy, in particular in the form of capacitive transformers and / or inductive transformers, can also be arranged in or on the receptacle.

The hob advantageously includes devices for communication and / or data exchange with internal and / or external databases, in particular for data exchange of process data for operating a preparation vessel, in particular assigned to the receptacle, these databases being referred to as recipe databases and access to these being licensed for a fee can be.

In particular, transmitters for this data exchange between the hob and the preparation vessel are advantageously arranged in or on the receptacle.

The transmitters can include emitters and receivers, in particular antennas for the transmission of electromagnetic signals, inductive and / or capacitive signals and optical signals, the transmitted signals complying with the ANT, ANT ⁺ , Bluetooth, NFC, Wifi and / or a user-specific standard .

In a further embodiment, the hob has in particular preferably at least one near or on the receptacle Display and / or a control panel.

In the presently disclosed hob, the bottom of the trough can be sunk or designed to be sunk, in particular sunk or sunk to such an extent that the hob, in particular in the sunk state of the trough, by means of a cover assigned to the receptacle, is preferably essentially flat and preferably towards the top can be covered in a fluid-tight manner manually or by a motor.

If at least one opening for a vapor extraction is assigned to the receptacle of the preparation vessel, which opening is preferably formed adjacent to the receptacle of the preparation vessel in the hob plate, considerable advantages can be achieved as a result. In general, this means that not only is a vapor extractor still available for conventional cooking vessels arranged on the hob, but the vapor extractor can then also include the preparation vessel disclosed in the present case through this opening. This is advantageous in comparison to a preparation vessel designed as a single device, for which a vapor extractor is generally not available as a single device.

The fume extractor is preferably used effectively with the preparation vessel on its own or can also include conventional cooking vessels arranged on the hob plate, in particular through manual or automated setting of the amount of fluids, in particular vapors, withdrawn per unit of time. With an extremely compact design, a fume extractor fulfills a double function for both types of cooking, that of a conventional hob and that of a preparation device according to the invention, which is only made possible by integrating a preparation vessel into the hob equipped with a fume extractor as disclosed herein.

In a preferred embodiment, fluids, in particular fluids released during a cooking process within the preparation vessel or within a cooking vessel arranged on the hob plate, can then advantageously be drawn off through the opening of the vapor exhaust into a fluid duct arranged under the hob plate, with the fluid duct being preferred , in particular to enable a particularly compact design, can be arranged inside the hob, preferably surrounding the base station of the preparation vessel, and the fluids drawn off can be discharged to the outside of the hob by means of the fluid guide.

By means of a preferred embodiment of the cover assigned to the receptacle of the preparation vessel, the base station can be closed in a fluid-tight manner without covering a substantial part of the at least one opening of the vapor extractor. As a result, the advantages of a fume extractor integrated into the hob can still be made available without a preparation vessel inserted in its receptacle, and the base station may be used during cooking processes effectively protected against leaking fluids.

If the at least one opening for the vapor extraction in a preparation vessel arranged in the receptacle surrounds this laterally, running at least over a section of the outer circumference of the preparation vessel, an advantageous use of the surface of the hob plate can be achieved, especially if the receptacle for the preparation vessel is arranged centrally in the hob plate, then not only a very compact design can be achieved, as shown for example in Figures 9 and 16, but also conventional cooking vessels arranged on the hob plate can be achieved fluidly and effectively through the vapor extraction.

If the at least one opening of the vapor vent comprises a plurality of openings which are formed by projections extending laterally opposite the receptacle of the preparation vessel, between which lateral support areas for the preparation vessel are formed, which in particular hold or support laterally a preparation vessel arranged in the receptacle, this provides a particularly user-friendly embodiment. The lateral support areas thereby not only form a guide for the preparation vessel when it is arranged on or in the hob plate, but also stabilize it during operation, for example during chopping or stirring processes, which cause excessive vibrations The preparation vessel.

The lateral projections can advantageously extend in an essentially ring-shaped cover plate, which can be inserted into an associated opening in the hob plate and can be arranged on the preparation vessel. By removing this cover plate, a larger area of the fluid guide of the vapor exhaust can be provided for cleaning it or for removing or attaching vapor filters. In addition, this embodiment is cost-effective in comparison to the introduction of several openings in the hob plate, as would be the case with an opening for the vapor extraction that is arranged separately from the receptacle of the preparation vessel.

In a further embodiment, a forced fluid or air duct can be configured in a fluid-carrying connection with the base station and with at least one further electronic device.

Electronic assemblies, in particular an electronic sub-unit of an inductive heating device of the hob, as well as assemblies of the base station or the base station of the preparation vessel and the housing for fluid guidance of the fume extractor can also advantageously be connected to a common fluid conveying device, in particular a common fan unit, to conduct air or fluid , in particular to the aforementioned assemblies inexpensive and with reduced space requirements with only a single To detect fluid delivery device.

When electronic assemblies, in particular an electronic sub-unit of an inductive heating device of the hob, as well as assemblies of the base station or the base station of the preparation vessel and the housing for fluid guidance of the fume extractor are connected to a common fluid conveying device, in particular a common fan unit, to conduct air or fluid, with an independently controllable fluid or air volume control device is assigned to the housing for guiding fluid of the fume extractor and an air duct for guiding air from electronic assemblies, in particular the electronic sub-unit of an inductive heating device of the hob, as well as air from assemblies of the base station, can independently meet the requirements of the Fume extraction as well as the cooling requirement of the electronic assemblies and assemblies of the base station can be met with only a single fluid conveying device with reduced space requirements.

The hob can advantageously have edge protection and / or vibration protection for an associated preparation vessel.

In a further embodiment, the hob has a heating device, preferably an inductive heating device, in particular in or near the receptacle, by means of which a cooking vessel of a preparation vessel assigned to the hob can also be heated. This enables For example, in the case of a receptacle provided with the assigned cover, cooking or boiling processes can also be carried out in this area of the hob.

Here and in the context of the present disclosure, the statement “in the vicinity” denotes a distance which is less than the distance to a further cooking surface of the hob that is closest in each case.

A preparation vessel for receiving in or on a hob comprises at least one functional device which is assigned to a functional device, in particular a functional device of a base station, which is preferably located in the vicinity of or on the mounting of the hob.

In an embodiment disclosed in the present case, conventional preparation vessels which have already been acquired with their base station can also be used with the presently disclosed hob together with its corresponding receptacle.

The functional device of the

Preparation vessel comprise a mechanical coupling device for coupling, in particular for non-rotatable coupling with an associated mechanical coupling device of an associated receptacle in a hob.

Transmitters for electrical energy, in particular in the form of coupling parts or contact pins on the preparation vessel, in particular on a Be arranged base assembly of the preparation vessel.

Here, the transformers for electrical energy, in particular in the form of capacitive transformers and / or inductive transformers, can be designed.

In addition, heating devices and / or thermal sensors can be arranged on the preparation vessel, which advantageously allow defined, time-controlled temperature profiles to be implemented within the preparation vessel, in particular with foodstuffs or their preliminary products arranged therein.

In addition, the preparation vessel can include transmitters for exchanging data with transmitters of an associated hob.

These transmitters can include emitters and receivers, in particular antennas for the transmission of electromagnetic signals, inductive and / or capacitive signals and optical signals, the transmitted signals preferably complying with the ANT, ANT ⁺ , Bluetooth, NFC, Wifi, and / or user-specific standards Standard.

Detailed description of the preferred embodiments

In the following detailed description of the presently disclosed embodiments, the same reference symbols designate the same or identically acting components of the embodiment shown in each case. The figures are not shown to scale merely for the sake of clarity and for better understanding.

In the following, for the sake of better understanding, reference is first made to FIG. 6, which is a representation shown partially in cross section

Preparation device 1, in which the preparation vessel 2 is arranged in a conventional base station 3, in a highly schematic form.

The preparation vessel 2 has an essentially cylindrical lower part 4, on which the vessel part 5 for receiving food 6 to be prepared or the preliminary products thereof is arranged.

The vessel part 5 can consist of a metal or glass or glass ceramic or comprise metal or glass or glass ceramic.

Stainless steel and aluminum are particularly suitable as metals, since these are also particularly suitable for inductive heating.

The preparation vessel 2 can have additional assemblies, such as a lid to cover the vessel part 5,

Steam cooking attachments or attachments for keeping food warm, which are known to those skilled in the art and are consequently not explicitly shown in the figures. A liquid food 6, which forms a liquid surface 7, is shown as food 6 in FIG. 6 merely by way of example.

The head 8 of a stirring, chopping and / or

The cutting device 9 protrudes into the food 6 or is completely surrounded by it. In the context of the present disclosure, these form a device for comminuting, which is suitable for foodstuffs or preliminary products of foodstuffs and is provided for comminuting them.

The device for comminuting, however, is not limited to stirring, chopping and / or cutting devices, but includes any mechanical device which is suitable for comminuting foodstuffs or their preliminary products. The device for comminuting can thus also comprise a grinder for grinding the foodstuffs or their preliminary products or also a mortar.

The stirring, chopping and / or cutting device 9 has a drive shaft 10 which is non-rotatably connected to the head 8 and, with reference to FIG.

The drive shaft 10 is held both in the vessel part 5 and in the lower part 4 so as to be rotatable and fluid-tight. At the lower end of the drive shaft 10, a coupling part 11 is also connected non-rotatably to the drive shaft 10 and is in detachable non-rotatable engagement with an associated mechanical coupling part 12 of the base station 3.

Various forms of a detachable, non-rotatable mechanical connection are known to those skilled in the art, by means of which a rotary drive, for example the head 8 of the agitating, chopping and / or cutting device 9, can be implemented, so that the representations in the accompanying figures are to be regarded as merely exemplary .

In order to set the head 8 in rotation, an electric motor is arranged in the base station 3 together with its electrical or electronic control and the associated electrical power supply, which is known to the person skilled in the art, but is not explicitly shown in the figures.

The base station 3 forms a foot part 13, which receives the aforementioned electric motor and its electrical and / or electronic control and the associated electrical power supply and a base section 14 in which electrical coupling parts 15 to 19 are formed, in which associated electrical contact pins 20 to 24 extend when the preparation vessel 2 is inserted into the base station 3. A heating device 25 is arranged below the vessel part 5, which can be supplied with electrical energy by means of at least two electrical coupling parts 15 to 19 and contact pins 20 to 24 assigned to them in order to heat food 6 located in the vessel part 5 under the control of the base station 3.

A preferably electronic temperature sensor 26 can be used to measure the temperature of the vessel part 5 and, indirectly, as well as in the event of temperature changes with a time delay, the temperature of the food 6 can be measured as a result.

For this purpose, the temperature sensor 26 is also connected to the base station 3 by means of at least two electrical coupling parts 15 to 19 and contact pins 20 to 24 assigned to them, which records its sensor data and compares them with assigned data from an internal or external recipe database.

If the vessel part 5 is made of glass or glass ceramic or comprises at least areas made of glass or glass ceramic, electromagnetic radiation, such as visible light or thermal radiation, can usually be passed through the glass or the glass ceramic material and detected by sensors and evaluated electronically.

The temperature of the food can then be detected by means of the optical sensor 27, which is within from his field of view S, shown bordered by dashed lines, can detect the temperature radiation emitted by the food 6 and convert it into electrical signals by sensors, which can be transmitted to the base station 3 by means of at least two electrical coupling parts 15 to 19 and contact pins 20 to 24 assigned to them, as well as lines not shown and can be evaluated by this.

Two further optical assemblies 28 and 29 form a light barrier in which the light beam L shown in dashed lines above the liquid surface 7 can initially pass unhindered through the vessel part 5 of the preparation vessel 2.

If, however, the food 6 begins to cook as it continues to be heated, fluid components of the food 6 will enter the path of the light beam L and will be detected by the light barrier formed by the optical assemblies 28 and 29. The optical assemblies 28 and 29 are each connected to the base station 3 by means of at least two electrical coupling parts 15 to 19 and contact pins 20 to 24 assigned to them, as well as lines not shown, and can consequently transmit corresponding sensory data to the base station 3.

The above-mentioned optical sensors 27 and optical assemblies 28 and 29 as well as their use described here are already developments of a conventional base station 3, which by the inventors of present invention. The same applies to the vessel part 5 of the preparation vessel consisting of glass or glass ceramic or comprising glass or glass ceramic

2.

For such a preparation vessel 2, the invention provides a receptacle 30 in a hob 31, on or in which the preparation vessel 2 can be placed and which can be seen in a first embodiment from the partially cross-sectional view of FIG.

In the context of the present disclosure, the cooktop is understood to be that assembly, preferably also independently manageable and tradable, which forms an upper side facing a user with its associated surface 32, on which cooking vessels 33 can be arranged and at least food 6 located therein by means of heating devices 34 of the cooktop 31 can be heated.

By way of example, such a hob 31 is shown in FIG. 8 in a view obliquely from above from the perspective of a typical user.

The heating devices 34 of the hob 31 can be thermal radiators or inductive heating devices 34, as these are well known to those skilled in the present technical field and are only shown schematically in the figures. Cooking devices heated with gas can also be part of a corresponding hob 31. Such hobs 31 can be independently manageable assemblies with all associated electrical and electronic supply devices or form part of a more complex assembly, for example an assembly integrated into a more complex smart home application and both via display fields 35 and via control panels 36, in particular touch-enabled control panels 37 have.

By means of the control panels 36 and 37, all operating processes of a conventional base station 3 can be carried out in relation to the preparation vessel 2, and the display panel 35 is suitable for realizing all messages as well as the user guidance of a conventional base station 3.

With the control panels 36 and 37, however, all operating and control processes of a conventional hob can be carried out and the display panel 35 is also suitable for corresponding user guidance.

The control panels 36 and 37 thus each form an operating and control unit which is functionally assigned to both the hob 31 and the preparation vessel 2.

The display field 35 is also suitable for providing all messages as well as the user guidance of a conventional hob and thus forms a display unit that is also functional to both the Hob 31 and the preparation vessel 2 is assigned.

A "normal", that is conventional control via a single TFT screen is possible for the entire preparation device 56, this means for the hob 31 and the preparation vessel 2, if, for example, the display field 35 is designed as a touch-enabled TFT screen.

In a particularly advantageous manner, illuminated or self-illuminating areas integrated into the hob 31, such as CERAN EXCITE® from Schott AG, can additionally or alternatively be used for user guidance.

A further advantage of the presently disclosed preparation device 56 is a uniform operator guidance for the preparation vessel 2 and the hob 31, which can also have a uniform operator logic and no longer has to have separate databases for the hob 31 and the preparation vessel 2, but these Merge and share data in a single database. Thus, the presently disclosed preparation vessel 2 differs from conventional food processors, since it is integrated into the entire operator guidance of the preparation device both with its sensors and its functional devices and, in certain embodiments, can also be integrated into the automated control of a fume extractor. According to the invention, the presently disclosed hob 31 comprises at least one receptacle 30 for a preparation vessel 2 and at least one functional device, in particular a functional device of a base station of a preparation device, in particular a food processor, which is preferably assigned to a functional device of the preparation vessel.

In the context of the present disclosure, a functional device is understood to mean a device which can perform a function on or in the preparation vessel 2, in particular on or in its vessel part 5, during the processing or preparation of foodstuffs or their preliminary products.

Functions within the vessel part 5 of the preparation vessel include, given below in a non-exhaustive list: heating a food or an intermediate product, in particular frying, steaming, cooking, cooling a food or an intermediate product, stirring, kneading, the Mixing, cutting, chopping, grinding, fermenting, permanent slow cooking (so-called "slow cooking"), steam cooking, foaming the food or an intermediate product, recording the temperature and / or the thermal radiation of a food or preliminary product within the vessel part 5. Correspondingly and as will be described in greater detail below, associated functional devices each comprise devices which support or implement the functions mentioned above.

By means of the head 8 of the stirring, chopping and / or cutting device 9 arranged in the vessel part 5 of the preparation vessel 2, food arranged in the vessel part 5 can, for example, be stirred, kneaded, mixed, ground, fermented, permanently cooked gently (so-called "slow cooking"), be cooked with steam, foamed or chopped, depending on how fast the head 8 provided with cutting blades is rotated.

If the cutting knives of the head 8 have cutting in one direction of rotation and a blunt surface in the opposite direction of rotation, careful stirring can also be carried out without cutting the food 6 when the head 8 is rotated in the direction of the blunt surface.

A first embodiment can comprise a hob 31 with a receptacle 30 for a preparation vessel 2, which has a stirring, chopping and / or cutting device 9, in particular as a functional device.

In this embodiment, the functional device of the receptacle 30 comprises a mechanical coupling device, preferably with a coupling part 12, which is the coupling part of a conventional base station 3 may correspond, for coupling, in particular for rotationally fixed coupling with an associated mechanical coupling device as a functional device of the preparation vessel 2 in the form of the coupling part 11.

Further functional devices can be electrical coupling parts and / or contact pins, as described later for the coupling parts 15 to 19 and the contact pins 20 to 24, and / or heating devices 25, temperature sensors 26, in particular optical temperature sensors 27, optical assemblies 28 and 29, capacitive or inductive transmitters 47, 48 as well as devices 49 and 50 for communication and / or for data exchange with internal and / or external databases, as will be described in more detail below.

The hob 31 shown in Figures 1 to 5 and 7 and 8 each has a hob plate 38, which forms a top facing the user with its surface 32 in which the receptacle 30 is arranged, the hob plate 38 consists of glass or glass ceramic or at least comprises glass or glass ceramic.

In this case, a recess 39 for receiving a lower part 4 of the preparation vessel 2 is formed in the surface 32 in particular, which recess is shown by a double arrow in FIG. 1 only by way of example. In general, the recess 39 can be designed as a trough 40, which forms a recess for receiving in particular the lower part of the preparation vessel 2, whereby the preparation vessel 2 in its operating position in the receptacle 30 protrudes less over the hob plate 38 and also against, for example, unwanted lateral shifts or tilting is secured when handling cooking utensils, which is particularly advantageous when there are heated food in the vessel part 5 of the preparation vessel 2.

As shown for example in FIG. 7, an embodiment of the trough 40 which allows as little play as possible to the side of the lower part of the preparation vessel 2 can further support the stability of the preparation vessel 2 in its operating position.

Alternatively, in a very simple embodiment, the hob 31 can only comprise an opening in the hob plate as a recess 39 which defines a stand for the preparation vessel 2 on which the functional devices of a base station 3 assigned to the preparation vessel 2 are formed.

In the case of the hobs 31 disclosed in the present case, the bottom 41 of the trough 40 is arranged sunk relative to the surface 32 and, moreover, can also be designed so that it can be lowered further.

A lateral part M, in particular an upper lateral part of the trough 40, which is directly, as in FIG FIG. 2 can be seen below the dashed line downwards, extending in the direction of the bottom 41 of the trough 40, made of glass or glass ceramic, in particular in order to further promote the resistance of the receptacles 30 to temperature and thermal shock.

In FIGS. 3, 4 and 5, embodiments are shown in which the bottom 41 is sunk so far that the hob, in particular the opening 39, can be covered or even closed by means of a cover 42 assigned to the receptacle 30.

The cover 42 is preferably essentially flat and can be positively inserted into the receptacle 30, in which the latter can seal the hob 31 in a fluid-tight manner on the upper side with sealing means 43, in particular sealing lips or round cord rings, running around its outer circumference.

This results, in particular together with the inductive heating device 34, also above the cover 42, a hob which can be used in a known manner for conventional cooking vessels.

FIG. 4 shows a cover 42 that can be attached manually, in particular from above, which is arranged in the recess 39 of the receptacle 30 in a fluid-tight manner.

In FIG. 5, a motorized attachable or movable cover 42 is shown on the receptacle 30, by means of which the receptacle 30 is actuated by a motor, in the present case from the underside of the hob plate 38, can be covered in a fluid-tight manner.

For this purpose, the cover 42 is arranged on a support arm 44, which can be lowered from the position shown in FIG.

From the position pivoted to the side, if there is no preparation vessel 2 in the receptacle 30, the cover 42 can be pivoted by the lifting and pivoting device 45 under the recess 39 and then raised so that the recess 39 is covered in a fluid-tight manner.

Since the lifting and swiveling device 45 senses whether the swiveling and / or lifting movement described above counteracts a mechanical resistance, such a movement sequence can be interrupted immediately and a countermovement initiated, so that in particular injuries to a user or impairments due to soiling of the receptacle are avoided 30 do not have any adverse consequences. The detection of such a malfunction can be displayed on the display field 35 together with suggestions for remedial action.

Since, as can be seen by way of example from FIG. 7, the preparation vessel 2 stands with its lower part 4 on the bottom 41 of the trough 40, a weighing device 46, in particular for weighing the preparation vessel 2 with or without foodstuffs or preliminary products of foodstuffs arranged therein, can be provided in that the weight which the preparation vessel 2 exerts on the floor 41 of the base station 3 is measured. This can be done, for example, by means of piezoelectric sensors or other pressure or weight sensors known to those skilled in the art.

Here, as in the other embodiments disclosed herein, the base 76 of the hob 31 receives the base station 3 of the preparation vessel 2 in a load-bearing manner.

In the embodiments of the hob 31 described above, transmitters for electrical energy, in particular in the form of contact pins 20 to 24 or coupling parts 15 to 19, can be arranged in or on the receptacle 30.

Transmitters for electrical energy can, however, also, in particular, be arranged in the form of capacitive transmitters 47 and / or inductive transmitters 47 on the receptacle 30 of the hob 31, as can be seen from FIG.

Correspondingly assigned transmitters for electrical energy are then also arranged in each case, in particular in the form of capacitive transmitters 48 and / or inductive transmitters 48, on the foot part 4 of the preparation vessel 2, as this is likewise only illustrated by way of example and in a highly schematic manner the figure 7 can be seen.

Furthermore, devices 49 for communication and / or for data exchange with internal and / or external databases, in particular for data exchange of process data for the operation of the preparation vessel 2, both on the preparation vessel 2 itself, on the receptacle 30 or assigned to them in the hob 31 or in its vicinity can be present be.

Corresponding or assigned devices 50 for communication and / or for data exchange with internal and / or external databases, in particular for data exchange of process data for operating the preparation vessel 2, can also be attached to the preparation vessel 2 itself.

The devices 49 and 50 advantageously include transmitters for the data exchange between a hob assigned to the devices 49 and the devices 50 of the preparation vessel.

The transmitters of the devices 49 and 50 include emitters and receivers, in particular antennas for the transmission of electromagnetic signals, inductive and / or capacitive signals as well as optical signals, the transmitted signals complying with the standards ANT, ANT ⁺ ,

Bluetooth, NFC, Wifi, and / or a user-specific standard. This makes it possible, for example by means of Bluetooth or WiFi communication, to control both the preparation vessel 2 and the receptacle 30 with their respective assemblies via the app of a mobile device. The control devices required for this, which are usually operated under processor control, are not described in detail, however, since they are known to the person skilled in the art.

Integration in smart home applications, which can also be operated via a voice assistance device 52, for example, is also possible in this way.

For example, such

Voice assistance devices 52 be independent devices, such as, for example, Alexa ^R from Amazon ^R Germany GmbH or Echo ^R from Google ^R Germany GmbH, or also run on the mobile devices 51 in an application-controlled manner.

Alexa ^R , Amazon ^R , Echo ^R or Google ^R can be trademarked terms of their respective owners.

In a further embodiment, the hob 31 or its receptacle can also have an edge and / or vibration protection 53 for an associated preparation vessel 2, for example consisting of a temperature-stable elastomer or comprising it, as shown by way of example in FIG.

In addition, a device 54 for sound or noise protection made of a temperature-resistant, Sound-absorbing material can be provided on or in the receptacle 30, which is shown only by way of example in FIGS. 3 and 4 and surrounds the lower part 4 of the preparation vessel 2 in an essentially pot-shaped manner.

In the following, reference is made again to FIG. 8, which can be seen clearly that the receptacle 30 of the hob 31 can advantageously also be arranged under an extractor device 55, in particular an extractor hood, so that any fluids that may escape during operation of the preparation vessel 2, which in the frame of the present disclosure can also be referred to as vapor, can be withdrawn and a user has to be less affected by this.

Here, FIGS. 9 to 15 each represent an exemplary embodiment of a hob 31 in a view perpendicularly from above and the receptacle 30 for an associated preparation vessel 2 is provided with a cover 42 associated therewith.

In FIG. 9, a locally variable hob area 58 is arranged laterally on the left and another locally variable hob area 59 is arranged laterally on the right next to the receptacle 30 for an associated preparation vessel 2. The terms “laterally left” and “laterally right” relate to the perspective of an observer who is looking at the hob 31 from above approximately in front of the display field 35. The meaning of the terms “in front of” and “behind” is also understood from this point of view, so one object, such as for example the display field 35, lies in front of another when the latter is closer to the viewer. The display field 35 therefore lies in front of the receptacle 30 and consequently this receptacle 30 lies behind the display field 35.

In the case of a variable hob area, the position of a cooking vessel 33 is not strictly defined locally, but can be placed anywhere on the hob 31 in the area indicated by parallel lines and heated in such a position, for example by means of inductive energy supply.

FIG. 10 shows an exemplary embodiment in which a locally fixed hob area 60 is located on the right side and two further locally fixed hob areas 61, 62 are located in front of the receptacle 30 for an assigned preparation vessel 2.

A locally fixed hob area is understood to be an area within which a cooking vessel 33 should be arranged in order to be heated as completely as possible on its underside. These locally fixed hob areas 60, 61, 62 extend approximately in the area marked by crosses and can include thermal radiators, for example.

An independent assembly is understood to be an independently manageable assembly that can be provided, for example, in that the receptacle 30 and the display field 35 are arranged in their own hob plate 63, preferably also made of glass or glass ceramic like the hob plate 38.

FIG. 13 shows an exemplary embodiment of a hob 31 in which a locally variable hob area 58 is located to the right of the receptacle 30 for an assigned preparation vessel 2 and between the receptacle 30 for an assigned preparation vessel 2 and the locally variable hob area 58 there is an extractor device 55 in In the form of a vapor exhaust 64 is arranged in the hob 31, of which the inlet opening 65 for fluids can be seen in FIG. 13 as an example. So much for the revelation 13 to 15, reference is made to the vapor exhaust 64 in the embodiments shown in FIGS. 13 to 15, only its inlet opening 65 for fluids can be seen in these views and preferred embodiments of the vapor exhaust 65 are explained in more detail below with reference to FIGS. 16 to 20.

FIG. 14 shows an exemplary embodiment of a hob 31 in which the receptacle 30 for an associated preparation vessel 2 is provided with a cover 42 associated therewith and a locally variable hob area 58 is to the right of the receptacle 30 and the receptacle 30 for an associated preparation vessel 2 form an independent assembly 66 with the display field 35.

An extractor device 55 is arranged in the form of a vapor extractor 64 with its inlet opening 65 for fluids in the hob 31 between the receptacle 30 for an associated preparation vessel 2 and the locally variable hob area 58.

In this embodiment, the locally variable hob area 58 together with the control panel 36 form a further independent assembly 67 and the vapor extractor 64 also forms yet another independent assembly.

FIG. 15 shows an exemplary embodiment of a hob 31 in which two locally Variable hob areas 58, 59 are located laterally to the right of the receptacle 30 for an associated preparation vessel 2 and the receptacle 30 with a display field 35 and the locally variable hob areas 58, 59 form a further independent assembly 67 and yet another independent assembly 68.

In this embodiment, an extractor device 55 in the form of a fume extractor 64 is arranged in the hob 31 behind the receptacle 30 for an associated preparation vessel 2 and the locally variable hob areas 58, 59 as a likewise independent assembly.

In the following, reference is made to FIG. 16, which shows an exemplary embodiment of a hob 31 in a view vertically from above, in which the receptacle 30 for an associated preparation vessel 2 is preferably arranged centrally in the hob 31, this preferably means the centroid or the geometric center of gravity of the The hob.

A locally variable hob area 58 is located on the left side and another locally variable hob area 59 is located on the right side next to the receptacle 30 for an assigned preparation vessel 2.

The receptacle 30 of the preparation vessel 2 is assigned at least one opening 71a, 71b, 71c for a vapor extractor 64, which is preferably formed adjacent to the receptacle 30 of the preparation vessel 2 in the hob plate 38. The vapor extractor 64 comprises a fluid duct, which is designed as a housing 74 and is arranged under the hob plate 38, a fluid delivery device, preferably in the form of an exhaust fan 78, and at least one fluid channel 81 by means of which the extracted fluids 75 are discharged to the outside of the hob 31.

The fluid guide with its housing 74 is preferably connected in a fluid-tight manner within the hob 31 below the hob plate 38, and the base station 3 of the preparation vessel 2 is arranged laterally surrounding it.

Furthermore, the housing 74 also encloses the base station 3 in a fluid-tight manner at the edge, with at least the part of the base station 3 protruding into the housing 74 being essentially fluid-tight with respect to the interior 71 of the hob 31 located outside the housing 74.

As a result, fluids 75 released during a cooking process within the preparation vessel 2 or within a cooking vessel 33 arranged on the hob plate 38 can be drawn off through the opening 71a, 71b, 71c and discharged along the fluid channel 81 to the outside of the hob 31 by means of the vapor extractor 64 will.

The fluids 75 drawn off can be passed through a vapor filter 80, shown for example in FIG Covering the underside of the openings 71a, 71b, 71c, so that the fluids 75 drawn off can be cleaned of undesired constituents.

In a further embodiment, the at least one opening 71 of the vapor vent 64 comprises a plurality of openings 71a, 71b, 71c, which are formed by projections extending laterally opposite the receptacle 30 of the preparation vessel 2 or radially with respect to the geometric centroid of the receptacle 30 and with a The preparation vessel 2 arranged in the receptacle 30 surrounds this laterally, running at least over a section of the outer circumference of the preparation vessel 2.

Lateral support areas 72a, 72b, 72c for the preparation vessel 2 are formed between the openings 71a, 71b, 71c. These lateral support areas 72a,

72b, 72c can hold a preparation vessel 2 arranged in the receptacle 30 laterally or support it laterally and thereby introduce into the hob plate 38, in particular lateral forces originating from the preparation vessel 2, for example caused by vibrations of the preparation vessel 2.

In a further embodiment, the lateral projections 72a, 72b, 72c can extend in an essentially ring-shaped cover plate 79, which can be inserted into an associated opening 69 in the hob plate 38 and which can be removed independently. The opening 69 surrounds the receptacle 30 preferably in a radially or cylindrically symmetrical manner. In this embodiment, the receptacle 30 comprises a partial area, in particular a recess partial area 70 of the opening 69.

The essentially ring-shaped cover plate 79, which can be removed independently from the hob plate 38, is shown by way of example in FIG Hob 31 can be removed or inserted into it.

In this embodiment, the essentially ring-shaped cover plate is raised and can rise with its edge 87 laterally above the hob plate 38 and rest with this lateral edge 87 on its surface.

Furthermore, in this embodiment, the cover plate can also be made in two parts and in this case comprise the cover plate 79 shown in FIGS 87 forms and can be releasably attached to the preparation vessel 2. In this embodiment, the section 88 of the cover plate together with the preparation vessel 2 can be removed from the hob 31 and in particular the essentially ring-shaped cover 79 on the hob 38 remain and cover this at least partially even after the preparation vessel 2 has been removed. Furthermore, the hob plate 38 and the cover plate 79 with the projections 72a, 72b and 72c can also be designed as a one-piece, preferably also as a flat hob plate, in particular without an elevation.

Furthermore, the preparation vessel 2 can also be inserted into the receptacle 30 of the hob 38 without an annular cover 79 or cover plate 79 with suitable ventilation openings.

Reference is made below to FIG. 19, which shows a representation, partially shown in cross section, of a hob 31 with a further embodiment of a cover 82 for receiving the preparation vessel 2.

If no preparation vessel is inserted in the hob 31, the receptacle 30 can be covered by a cover 82 assigned to it and the base station 3 can be closed in a fluid-tight manner with an elastic collar 83 protruding downward from this.

The cover 82 also has a lateral edge 87 by means of which the cover 82 can be carried by the hob 83 and which provides a defined support for the cover 82, which ensures that the collar 83 overlaps the base station 3 with sufficient mechanical contact complete this fluid-tight. The cover 82 is equipped with through-openings 89a, 89b, 89c in such a way that the vapors 75 can be drawn off through this cover 82, because these through-openings, of which only the through-openings 89a and 89b are shown in FIG. 19 due to the selected sectional plane, have approximately similar or larger lateral dimensions as the openings 71a, 71b and 71c of the vapor exhaust 64.

Although the cover 82 has a suitable

Alignment device for their correct alignment relative to the hob plate 38, the through openings 89a, 89b, 89c with their lateral dimensions ensure that even if these are arranged rotated relative to the openings 71a, 71b and 71c of the fume extractor 64, the openings 71a , 71b and 71c of the vapor extractor are not covered to a significant extent and the vapor extractor 64 remains functional even in this position of the cover 82.

As an alternative or in addition to the through openings 89a, 89b, 89c, a grid or fabric can also be arranged as a one-piece circumferential area on the cover 82 of the receptacle 30.

Alternatively, the cover 82 with the

Through openings 89a, 89b, 89c and the cover plate 79 formed in one piece with the openings 71a, 71b, 71c. The lower edge of this cover can, but does not have to be, with the Complete the lower edge of the hob plate 38, as shown in FIG.

A cover 83, preferably as part of the cover 82, preferably covers the base station 3, preferably airtight, so that vapor cannot get into the internal structure with the coupling parts, such as 12, and contaminate the internal part

Reference is made below to FIG. 20, which shows the hob 31 shown in FIG. 19 with additional functional groups attached to it.

Modern hobs are increasingly being operated with induction heating. The power electronics contained in an induction subunit 84 usually require forced ventilation, since considerable waste heat is generated here. Likewise, an electric motor in a base station 3 is usually provided with forced ventilation. With another

Embodiment of the presently disclosed hob, the two ventilation devices, that which is contained in the induction subunit 84 and that of the base station 3, can advantageously be combined.

The subunit 84 or other electronic devices and the base station 3 are each connected to a ventilation duct 85a, 85b in such a way that the cooling ventilation flow through the subunit 84 through the ventilation duct into the base station 3 and through it by means of the ventilation duct 85b a common fluid delivery device, in particular a fan unit 86.

This provides a forced air duct with an air-conducting connection 85a between the base station 3 and at least one further electronic device, which is embodied here as an example as a sub-unit 84, by means of which waste heat from the hob interior 77 into the surroundings and thus to the outside of the hob plate 38 is discharged.

In the following, reference is made to the embodiment shown in Figure 21, in which electronic assemblies, in particular an electronic sub-unit 84 of an inductive heating device of the hob 31, as well as assemblies of the base station 3 of the preparation vessel 2 and the housing 74 for fluid guidance of the fume extractor 64 with a common fluid delivery device 90, in particular a common fan unit, are connected to conduct air or fluid. In this embodiment, too, the sub-unit 84 or other electronic devices and the base station 3 or assemblies thereof are each connected to a ventilation duct 85a in such a way that the cooling ventilation flow through the sub-unit 84 through the ventilation duct into the base station 3 and through it are guided by means of the ventilation duct 85b to a common fluid delivery device, in particular a fan unit 90. Instead of the air duct 85b, however, the housing 74 of the fume extractor 64 is designed in such a way that it also feeds the air discharged from the electronic subunit 84 and passed through the base station 3, together with the extracted and preferably cleaned fluids 75, to the common fluid delivery device 90.

FIG. 22 shows a representation of a hob 31, shown partially in cross section, which essentially corresponds to the embodiment shown in FIG Air volume control device 91, 92 the

Amount of the common fluid or

Air flow control device 91, 92 supplied fluids or

Air each independently for the fume extractor 64 as well as the base station 3 and other electronic units 84 regulates.

The electronic assemblies, in particular an electronic sub-unit 84 of an inductive heating device of the hob 31, as well as assemblies of the base station 3 or the base station 3 itself are connected by means of an air duct, in particular the ventilation duct 85a, and by means of the ventilation duct 85b also to the common fluid delivery device 90, in particular a common fan unit carrying air, connected.

Also the housing 74 for the fluid guidance of the vapor exhaust 64 is connected to the common fluid delivery device 90 in an air or fluid-guiding manner.

In this embodiment, an independently controllable fluid or fluid is in the housing 74

Air quantity regulating device 91, in particular in the form of an electronically controlled and regulated valve device, for example arranged as a motor-driven pivotable valve flap.

With this fluid or air quantity regulating device 91, the delivery requirement of the vapor exhaust 64 can be regulated independently, this regulation interacting with the regulation of the common fluid delivery device 90 in such a way that the necessary delivery requirement is always provided.

The air duct for guiding air from electronic assemblies, in particular the electronic subunit 84, as well as air from assemblies of the base station 3 or the base station 3 is an independently controllable fluid or

Air quantity regulating device 92, likewise in the form of an electronically controlled and regulated valve device, for example assigned as a motorized pivotable valve flap.

With this fluid or air quantity regulating device 91, the pending delivery requirement for the air duct 85b can be regulated independently, this regulation being so with the regulation of the common fluid delivery device 90 works together to ensure that the necessary funding is always available.

By jointly regulating the fluid or air quantity regulating device 91, the

Air volume control device 92 and the common fluid delivery device 90 can be provided with a particularly low-noise and energy-saving operation, since they only have to provide the corresponding delivery requirement in a regulated manner and thereby provide a

Allow minimal operation of the common fluid delivery device 90.

In a further embodiment, the sensors of the preparation vessel 2, in particular the optical assemblies 28 and 29, can be used to detect the vapors occurring in the preparation vessel in order to provide an automated control of the fume extractor 64.
