Dishwashers, washing machines and tumble dryers are known, which can be connected to an intelligent power network and have a corresponding communication unit allowing the sending of data to and the receiving of data from the intelligent power network. This allows an operating cycle to be started with a time delay so that power is only taken from a power network when the consumer load on the power network is relatively small.
The object of the invention is in particular to provide a cooking appliance apparatus having improved characteristics in respect of ease of operation. According to the invention the object is achieved by the features of claim 1 and the method claim 9. Advantageous embodiments and developments of the invention will emerge from the subclaims.
A cooking appliance apparatus, in particular a cooktop apparatus, is proposed, having a power unit, a communication unit for receiving at least one information item from a data network and a control unit, which is provided to change at least one operating parameter of the power unit at least as a function of the at least one information item. “Provided” here means in particular specifically designed and/or equipped and/or programmed. A “power unit” refers in particular to the unit of a cooking appliance which has a maximum power uptake in at least one operating state and is preferably provided for heating purposes. A “communication unit” refers in particular to a unit that is different from an input unit and communicates with other devices, in particular a computation unit that is different from the control unit and/or a power meter, in particular by way of cable and preferably at least partially without cable, and which in particular obtains at least one information item from there. In particular the other device is a device in a data network, in particular in the internet and/or in a domestic network and/or in an intelligent power network. An “input unit” here and in the following refers in particular to an operating unit, which is provided to allow an operator to input and/or change an operating parameter. The input unit is preferably provided for manual inputting and/or changing, in particular by means of operating elements provided for the purpose. An “intelligent power network” refers in particular to a communication-based networking and/or control of power generators, electrical energy storage units, electrical consumers and/or network operating means in energy transmission networks and/or energy distribution networks of an electricity supply. A “control unit” refers in particular to a unit, which is provided to control and/or regulate the power unit. The control unit preferably comprises a computation unit, in particular a microprocessor unit, and in particular a storage unit that is different from the computation unit, in which a control and/or regulation program is particularly advantageously stored. An “operating parameter” refers in particular to a physical variable of an operating state of the power unit. A value of the operating parameter is preferably always different from zero. The operating parameter is in particular different from a logical variable, which can in particular only have two values. The operating parameter is in particular different from a logical variable, which characterizes an activation state of the power unit. Such an embodiment allows an advantageously greater ease of operation to be achieved. In particular it allows remote control and/or remote maintenance of a cooking appliance comprising the cooking appliance apparatus.
In one preferred embodiment of the invention it is proposed that the at least one operating parameter is a power parameter, which sets a maximum power of the power unit. The power parameter is preferably a maximum electric current that can be supplied as a maximum to the power unit, in particular by a power supply of a private household. This allows automatic adjustment of a maximum power of a cooking appliance, in particular to a domestic electrical installation. In particular data relating to the available maximum power of individual consumers connected to the domestic installation can be available in the data network, allowing the communication unit to access said data.
In one particularly preferred embodiment of the invention it is proposed that the communication unit is provided to connect the control unit to an intelligent power network. This can reduce energy costs, as a specified power can be supplied as a maximum to the power unit as a function of the availability of electric power in the power network and therefore as a function of price per unit of electrical energy. If the cooking appliance is configured as an oven with a pyrolysis function, pyrolytic self-cleaning can preferably take place when there is a relatively high availability of electric power in the power network. Also, in the event of a power quota system, when an overall power consumption of all the consumers connected to a domestic installation is to be below a limit value, a maximum power of the cooking appliance can be limited to comply with the limit value.
It is further proposed that the cooking appliance apparatus has an input unit for inputting operating parameters of the power unit. This allows ease of operation to be particularly advantageously enhanced, as a setting for the at least one operating parameter obtained by the communication unit can be overwritten by an operator if required. Thus for example an operator can increase a power parameter manually if this is necessary for a cooking process.
The control unit is advantageously provided to change the at least one operating parameter of the power unit at least as a function of at least one information item which the control unit obtains by way of the input unit. This allows ease of operation to be advantageously enhanced, as an operator can perform manual overwriting of the power parameter if the power parameter of the power unit is disadvantageously low.
In a further embodiment of the invention it is proposed that the cooking appliance apparatus comprises an output unit for outputting operating parameters of the power unit. An “output unit” refers in particular to a unit, which is provided for the optical and/or acoustic and/or tactile and/or electronic outputting of an operating parameter. The output unit preferably comprises a display unit, preferably an LCD display, and/or a communication interface, which is provided for the electronic outputting of the operating parameter. The communication interface advantageously supplies the operating parameter in an electronically encoded manner so that it can be read electronically, in particular by a computation unit and preferably for further processing by the computation unit. This creates an advantageous transparency for an operator so that said operator is informed about the operating state of the power unit at all times and can intervene by way of the input unit if required.
The control unit is advantageously provided to output a current value of the at least one operating parameter by way of the output unit. This allows an advantageously high level of ease of operation to be achieved, as an operator can obtain information about the operating parameter at any time.
It is further proposed that the communication unit is configured at least partially as a single piece with the control unit. The statement that “the communication unit is configured at least partially as a single piece with the control unit” suggests in particular that the communication unit is integrated at least partially in the control unit. The communication unit and control unit are preferably disposed within a single electronic module and preferably on a single electronic printed circuit board. This can advantageously reduce the material and assembly outlay. It also reduces weight.
A method with an inventive cooking appliance apparatus, in particular a cooktop apparatus, having a power unit is also proposed, wherein at least one information item is received from a data network and at least one operating parameter of the power unit is changed at least as a function of the at least one information item.
A cooking appliance, in particular a cooktop, having an inventive cooking appliance apparatus is also proposed.
