Description

Cooking device device

The invention relates to a cooking appliance device, in particular a hob device, according to the preamble of claim 1.

A hob is already known from the prior art, which has two inverters and four inductors, with half of the inductors each being assigned to one of the inverters. Alternatively, half of the inductors can be assigned to both inverters, but in this state the other half of the inductors are not assigned.

The object of the invention is in particular, but not limited to, to provide a generic device with improved properties in terms of flexibility. The object is achieved according to the invention by the features of claim 1, while advantageous configurations and developments of the invention can be found in the subclaims.

The invention is based on a cooking appliance device, in particular a Kochfeldvor direction, with at least one inverter, at least one further inverter, at least one inductor, at least one set of further inductors, which has at least one first further inductor and at least one second further inductor, and at least one Switching arrangement which assigns the inverter to the inductor in at least one operating state.

It is proposed that in the operating state the further inverter can be assigned to at least any further inductor of the set of further inductors, for example the first and / or the second further inductor, by means of the switching arrangement.

Such a configuration can, in particular, achieve improved properties with regard to flexibility. In particular, a cooking device device can thereby be provided which has improved properties with regard to a flexible allocation of inductors and thus in particular a flexible distribution of heating power. In particular, the heating power, in particular with regard to a Cookware configuration, can be assigned more flexibly to the respective cookware. In particular, a larger number of possible cooking utensil configurations can be operated by means of the cooking device, in particular due to the increased flexibility of the cooking device. In particular, a single cooking appliance device can be used to operate greater flexibility, in particular with regard to a combination of larger and smaller cookware. In this way, in particular, a high degree of flexibility can be made available to a user of the cooking appliance device. In particular, the user can distribute cooking utensils more flexibly on a hob plate. In particular, a high degree of flexibility can be achieved by means of a particularly cost-effective number of components. In particular, the cooking appliance device can in particular be adapted to the increasingly different sizes and properties of cooking utensils available on the market. In particular, limitations with regard to possible cookware configurations can be reduced and / or eliminated.

The cooking appliance device could, for example, be an oven device, advantageously a hob device and particularly advantageously an induction hob device. A "cooking device", in particular a "oven device", before geous under a "hob device" and particularly advantageously under an "induction onskochfeldvorrichtung" should in particular at least a part, in particular a subassembly, of a household appliance, in particular a cooking device, advantageously a cook field and particularly advantageously an induction hob. A cooking device having the cooking device device could, for example, be an oven and / or a microwave and / or a grill device and / or a steam cooking device. Before geous a domestic appliance designed as a cooking appliance is a hob and preferably an induction hob. A “hob device”, in particular an “induction hob device”, should be understood to mean in particular at least a part, in particular a subassembly, of a hob, in particular an induction hob, in which case accessory units for the hob can also be included, such as a sensor unit for external measurement of a temperature of a cookware and / or a product to be cooked. In particular, the hob device, in particular the induction hob device, can also include the entire hob, in particular the entire induction hob. The cooking appliance device advantageously has an inductor and a set of further inductors, wherein in particular the inductor and the further inductors of the set of further inductors can be designed to be at least substantially identical to one another. In particular, the inductor and the further inductors of the set of further inductors can in particular have identical components. Advantageously, the inductor and the other inductors differ only in their circuit arrangement. In this context, “at least substantially” is to be understood in particular to mean that a deviation from a predefined value deviates in particular by less than 25%, preferably less than 10% and particularly preferably less than 5% of the predefined value.

An “inductor” is to be understood here in particular as an element which has at least one induction coil and / or is designed as an induction coil and which is provided to supply energy, in particular in the form of an alternating magnetic field, to at least one receiving element in at least one operating state . The receiving element is designed in particular as a part and / or a subassembly group of a receiving unit and is provided in particular to receive the energy provided by at least one inductor. The recording unit can in particular be part of the cooking appliance device. Alternatively, it is conceivable that the receiving unit is designed as a unit that is independent of the cooking device device and / or as part of a further device that is independent of the cooking device device. The receiving unit can in particular be provided to be set up in an area above the inductor and / or the further inductor. The receiving unit could for example be designed as a cookware and in particular have at least one secondary coil as a receiving element for receiving the energy provided by the inductor and / or the further inductor. Alternatively or additionally, the receiving element could also be designed as a metallic heating means, in particular as an at least partially ferromagnetic heating means, for example as a ferromagnetic base of cooking utensils, in which eddy currents and / or magnetic reversal effects caused by the inductor when the heating unit is in an operating state that are converted into heat.

A “set of further inductors” is to be understood as meaning, in particular, a group of further inductors which, in particular, have at least one first further inductor has ductor and in particular at least one second further inductor. For example, the further inductors of the set of further inductors could differ, for example with regard to the envisaged power consumption and / or the envisaged power output and / or with regard to their geometry and / or their size. The further inductors of the set of further inductors are advantageously designed to be at least essentially identical to one another. It is particularly advantageous that at least a large part of the further inductors of the set of further inductors are formed from at least essentially the same electrical components.

In particular, the cooking appliance device has exactly one inverter and exactly one further inverter. The cooking appliance device advantageously has two further inverters, particularly advantageously three further inverters and preferably at least four further inverters. An “inverter” is to be understood in particular as an electrical unit which, in at least one operating state, provides a particularly high-frequency alternating current, in particular for the inductor and / or the set of further inductors. In particular, the inverter can have inverter switching elements, which can be designed in particular as IGBT, MOSFET, HEMT, JFET and / or as TRIAC. In particular, the inverter switching elements can be formed at least partially from a semiconductor material, such as silicon, silicon carbide and / or gallium nitride and / or from another semiconductor material that appears sensible to a person skilled in the art.

For example, the inverter and the further inverter could differ, for example with regard to the intended power consumption and / or the intended power output and / or with regard to their geometry, and / or their size and / or with regard to electronic components that form the respective inverter. The inverter and the further inverter are advantageously designed to be at least essentially identical to one another. At least a large part of the inverter and the further inverter are particularly advantageously formed from at least essentially the same electrical components.

A “switching arrangement” is to be understood in particular as an electrical unit which, in particular, has a plurality of switching elements. In particular, the switching arrangement is provided to convert the inverter and / or further inverters to the inductors and / or further inductors of the set of further inductors. assign to. A “switching element” is to be understood in particular as an electronic element which is provided to establish and / or separate an electrically conductive connection between two points, in particular contacts of the switching element. The switching element preferably has at least one control contact via which it can be switched. In particular, the switching element is designed as a semiconductor switching element, in particular as a transistor, advantageously as a bipolar transistor with a preferably insulated gate electrode (IGBT). Alternatively, the switching element is designed as a mechanical and / or electromechanical switching element, in particular as a relay.

For example, the cooking appliance device could have a control unit which controls the switching arrangement, in particular a configuration switching unit of the switching arrangement and / or a parallel switching unit of the switching arrangement, as a function of a cooking utensil configuration. In particular, the control unit establishes operating states, in particular by controlling the switching arrangement. A “control unit” is to be understood in particular as an electronic unit which is preferably at least partially integrated in a control and / or regulating unit of a cooking appliance and which is preferably provided for this purpose, in particular at least the inverters and / or the further inverters and / or to control and / or regulate a switching arrangement. The control unit preferably comprises a computing unit and, in particular, in addition to the computing unit, a memory unit with a control and / or regulating program stored therein which is provided to be executed by the computing unit. A “cooking utensil configuration” is to be understood as meaning, in particular, a number and / or a position and / or a nature of the cooking utensils set up, in particular cooking utensils set up on the hob. In particular, a large number of possible cookware configurations is conceivable. For example, the cooking utensil configuration is a combination of the number and / or position and / or nature of the cooking utensils set up. In particular, the control unit controls the switching arrangement, in particular a configuration switching unit of the switching arrangement and / or a parallel switching unit of the switching arrangement, depending on the Garge dish configuration so that an assignment of the inductors and / or the further inductors of the set of further inductors to the inverter and / or the further inverter at least essentially corresponds to the cookware configuration. This means that the control unit is intended in particular to control the switching Control order depending on the cooking utensil configuration in such a way that set up cooking utensils can be operated individually and heated at least substantially over the entire surface and with the heating power desired by the user, in particular in an operating state.

An “operating state” is to be understood in particular as a state of the cooking appliance device in which in particular at least one inductor and / or a further inductor of the set of further inductors, in particular for heating the cooking utensils, is operated. In particular, a large number of operating states are possible, which differ in particular with regard to the assignment of inverters to inductors. In particular, in an operating state, at least the inductor that is being operated is assigned to an inverter, for example the at least one inverter and / or the at least one further inverter.

In particular, in the operating state in which the inverter is assigned to the inductor, the further inverter can be assigned to at least one further inductor of the set of further inductors, for example the first and / or the second further inductor, by means of the switching arrangement. In particular, in the operating state in which the inverter is assigned to the inductor, the switching arrangement is provided to assign the additional inverter to any additional inductor of the set of additional inductors, for example the first and / or the second additional inductor. In particular, in the operating state in which the inverter in particular operates the inductor, any further inductor of the set of further inductors, for example the first and / or the second further inductor, can be operated in particular by the alternating current provided by the further inverter.

The fact that an inverter is assigned to an inductor is intended to mean in particular that the inverter is electrically connected to the inductor by means of the switching arrangement, in particular in order to achieve the operating state. In particular, this should also be understood by an assignment in the opposite direction. The fact that an inverter can be assigned to an inductor should in particular be understood to mean that the inverter can be electrically connected to the inductor by means of the switching arrangement, in particular in order to be able to achieve a further operating status. “Provided” is to be understood in particular as specifically programmed, designed and / or equipped. The fact that an object is provided for a specific function is to be understood in particular to mean that the object fulfills and / or executes this specific function in at least one application and / or operating state.

It is also proposed that the set of further inductors have at least one third further inductor. As a result, a cooking appliance device can in particular be made available which, in particular, has a particularly high degree of flexibility, in particular with regard to possible cooking utensil configurations. For example, the set of further inductors has at least one fourth further inductor, preferably at least one fifth further inductor. The set of further inductors particularly preferably has any number of further inductors.

It is also proposed that, in the operating state, the further inverter can be assigned to all further inductors of the set of further inductors at the same time by means of the switching arrangement. This means that the further inverter in the Betriebszu can supply all further inductors of the set of further inductors at the same time. In particular, in the operating state in which the switching arrangement in particular assigns the inverter to the inductor, the switching arrangement can assign the switching order to the further inverter at the same time to all further inductors of the set of further inductors. Advantageously, in the operating state, in particular through the assignment by means of the switching arrangement, the inductor can be operated by the inverter and, at the same time, all further inductors of the set of further inductors can be operated by the wide ren inverter. In this way, in particular, a high degree of flexibility, in particular with regard to possible cookware configurations, can be achieved. Since a more flexible cooking appliance device can be provided to a user, user satisfaction in particular can be increased. In addition, this makes it possible in particular to dispense with multiplexing, as a result of which, in particular, efficiency can be increased.

Furthermore, it is proposed that by means of the switching arrangement, any two adjacent inductors, for example the inductor and / or a further inductor of the set of further inductors, can each be assigned to different inverters.

As a result, especially when using small cookware, which is heated by exactly one inductor and / or exactly one further inductor, a high degree of flexibility, in particular with regard to its positioning on the hob, it will be sufficient. In particular, at least two cooking pans can be set up in any position, and each can be operated by inductors that are assigned to other inverters. For example, one of the inductors could be assigned to the inverter and another inductor of the set of further inductors could be assigned to the further inverter. In particular, two adjacent cookware, ie two cookware, which are placed adjacent to any position on the hob plate, can be operated with an individual heating power in each case. For example, any two adjacent inductors can be assigned to different inverters at the same time by means of the switching arrangement.

It is further proposed that the switching arrangement has at least one configuration switching unit, by means of which each of the inductors can be individually electrically separated from the inverters. In this way, in particular, a high degree of flexibility can be achieved, since in particular each inductor can be individually separated from the inverters. Furthermore, a high efficiency can be achieved as a result, since each of the inductors, which cannot be operated, can be electrically separated from the inverters and is therefore not supplied with alternating current. A “configuration switching unit” is to be understood in particular as an electrical unit which is provided to electrically separate each of the inductors individually from the inverters in at least one operating state and to electrically connect each of the inductors individually to the inverters in at least one further operating state. In particular, the configuration unit is provided to electrically isolate each inductor, which cannot be operated in the operating state, from the inverters. In particular, the configuration unit is provided to electrically connect each inductor, which is to be operated in the operating state, to the inverters. In particular, the configuration unit can electrically separate each of the inductors in any combination from the inverters and / or connect them to the inverters. For example, the configuration unit can electrically disconnect each of the inductors from the inverters at the same time and / or connect them to the inverters.

In addition, it is proposed that the configuration switching unit has at least one configuration switching element, which is shown in a circuit diagram between at least one of the in- ductors and at least one further switching element, in particular a parallel switching element of the switching arrangement, is arranged. In this way, in particular, a cooking appliance device with particularly high efficiency can be provided. The configuration switching element can in particular be designed as a switching element. In particular, the configuration switching element is connected directly to the at least one further switching element, which can in particular be a parallel switching element, or to a resonance capacitance. In particular, it is conceivable that the further switching element, which can in particular be a parallel switching element, is not installed. In particular, the configuration switching unit then has at least one configuration switching element which is arranged in a circuit diagram between at least one of the inductors and a resonance capacity of the cooking appliance device. A “resonance unit” is to be understood in particular as a unit that includes at least one resonance capacity, which is preferably formed by at least one capacitor, which is different from a damping capacity and / or a capacity that is connected in parallel to a switching element is. In particular, a resonance capacitance is formed by a combination of series and parallel connections of several capacitors. The resonance capacitance is, in particular, a component of an electrical oscillating circuit, in particular an electrical series oscillating circuit. The resonance capacitance is preferably connected in series with the inductor in at least one operating state, in particular via the configuration switching element, and is particularly advantageously provided to be charged via the inductor by at least one of the inverters. The resonance capacitance is arranged in particular on a side of the inductor facing away from the inverter when viewed in the direction of a conduction path. For example, at least one and preferably each of the inductors and / or at least one of the further inductors of the set of further inductors is operated in a full bridge circuit. In a full bridge circuit, the inductor is in common with a resonance capacitance, preferably connected in series with the inductor, between two voltage dividers formed by inverters in the bridge arm. At least one and preferably each of the inductors and / or at least one of the further inductors of the set of further inductors is preferably operated in a half-bridge circuit. In a half-bridge circuit, the inductor is arranged in the bridge branch between a voltage divider formed by at least one inverter and a voltage divider formed by two resonance capacitances. The configuration switching unit advantageously has at least two configuration switching elements, particularly advantageously at least three configuration switching elements, preferably at least four configuration switching elements and particularly preferably at least five configuration switching elements. For example, the number of configuration switching elements could correspond to a number of inductors.

It is further proposed that the switching arrangement has at least one parallel switching unit, by means of which the inverter and the further inverter can be switched in parallel. In particular, a “parallel switching unit” should be understood to mean an electrical unit which is provided to connect at least the inverter and the further inverter in parallel in at least one operating state. In particular, in at least the operating state in which the inverter and the further inverter are connected in parallel by means of the parallel switching unit of the switching arrangement, the inverters can simultaneously supply at least the inductor and / or one further inductor of the set of further inductors with alternating current. In particular, a particularly high heating output can be achieved hereby. Since a particularly high heating output can be made available to the user as a result, in particular user satisfaction can also be increased as a result. Furthermore, a higher flexibility can be achieved in this way, in particular with regard to possible assignments of inverters to inductors.

In addition, it is proposed that the parallel switching unit has at least one parallel switching element which is arranged in a circuit diagram between at least one of the inverters and at least one further switching element of the switching arrangement, in particular the configuration switching element. As a result, the inverter and the further inverter can be connected in parallel with particular component efficiency. In particular, a particularly high degree of flexibility can be achieved in this way, in particular with regard to possible cooking utensil configurations. In particular, a cookware can thereby be supplied with energy from several inverters. In this way, in particular, user satisfaction can thus be provided. The at least one parallel switching element could, for example, be designed as a switching element. Alternatively or additionally, it is conceivable that the parallel switching unit has at least one parallel switching element which, in a circuit diagram, is between at least the inductors and / or a further inductor of the set of further inductors and at least one further switching element of the switching arrangement, in particular the configuration switching element, is arranged. The parallel switching unit advantageously has at least two parallel switching elements, particularly advantageously at least three parallel switching elements, preferably at least four parallel switching elements and particularly preferably at least five parallel switching elements. For example, the number of parallel switching elements could correspond to a number of inverters.

It is also proposed that any number of inductors can be assigned to each of the inverters by means of the switching arrangement. In this way, in particular, a high degree of flexibility, in particular with regard to a possible number of inductors, which are operated in particular with the same heating power, in particular by the same inverter, can be achieved. In particular, a number of inductors that are operated by a common inverter can be selected with maximum flexibility as a result. In particular, each of the inverters can supply any number of inductors with alternating current by means of the switching arrangement. In particular, the inductors and / or the further inductors of the set of further inductors can be assigned to each of the inverters in any number and / or combination by means of the switching arrangement. Alternatively or additionally, any number of inverters could be assigned to each of the inductors by means of the switching arrangement.

Furthermore, it is proposed that at least one and preferably at least a large part of the inductors can be assigned to each of the inverters simultaneously or alternatively by means of the switching arrangement. The fact that at least one and preferably at least a large part of the inductors can be ordered “simultaneously or alternatively” to each of the inverters should be understood in particular to mean that the inductor and / or at least one further inductor of the set of further inductors in an operating state simultaneously can be electrically connected to each of the inverters of the cooking appliance device and, in a further operating state, individually to one inverter and / or any desired combination of inverters. In this context, the phrase “at least a large part of the inductors” should be understood to mean in particular a number of at least 50% of all inductors of the cooking appliance device. In particular, this makes it possible to achieve a particularly high level of flexibility, in particular with regard to the heating power required individually on a respective inductor. The cooking appliance device is not intended to be restricted to the application and embodiment described above. In particular, the cooking appliance device can have a number of individual elements, components and units that differs from a number of individual elements, components and units mentioned herein in order to fulfill a mode of operation described herein.
