Definitions

  • the present invention concerns an appliance system and a method for managing an appliance system.
  • Domestic power supplies are provided with meters having limited available power, generally between 3 and 6 kW.
  • the available power is the maximum level of power that can be drawn from the circuit; when this level is exceeded, the circuit trips.
  • Frequent tripping of the circuit entails inconvenience for the user and risk of damage to the user devices powered by the domestic power supply when the circuit trips.
  • induction hobs are used in place of gas hobs. They are an optimal choice in financial terms, in terms of energy efficiency and also safety since they are electrically operated and, heating the pans via a magnetic field without using a flame, they limit domestic accidents.
  • the operation of a single burner of an induction hob absorbs approximately 2000 W if used at maximum power, with even higher consumption peaks during start-up. However, if set to a lower power, the operation of a single burner consumes less electricity, in the order of 600W.
  • induction hob can therefore significantly increase the power required from the domestic power supply, with an increase in the risk of the circuit tripping if other appliances are also operating.
  • An object of the present invention is therefore to provide an appliance system, in which the risk of overloading the domestic power supply is limited.
  • the present invention concerns an appliance system comprising:
  • a further object of the invention is to provide a method for managing an appliance system which is capable of avoiding overload of the domestic power supply in a simple and inexpensive manner.
  • the present invention concerns a method for managing an appliance system in accordance with claim 15.
  • the reference number 1 indicates an appliance system comprising an induction hob 2, an electric oven 3 and a power management device 4.
  • system 1 does not comprise further appliances.
  • the system 1 comprises one or more further appliances such as, for example, dishwasher and/or microwave oven and/or washing machine and/or refrigerator, etc. connected to the same power management device 4.
  • further appliances such as, for example, dishwasher and/or microwave oven and/or washing machine and/or refrigerator, etc. connected to the same power management device 4.
  • the induction hob 2 and the electric oven 3 share the same electrical supply as they are integrated in one single free-standing structure normally defined "cooker” in technical jargon.
  • induction hob 2 and the electric oven 3 can be arranged in separate structures, for example built into different units of the same kitchen. In this case, the electrical supply of the electric oven and induction hob will probably not be shared.
  • the power management device 4 is configured to selectively limit the electrical power absorbed by the induction hob 2 on the basis of the operating conditions of the electric oven 3 and on the basis of a predefined value of maximum overall absorption PMax.
  • the value of maximum overall absorption PMax is preferably defined during installation by a skilled operator by means of a suitable set-up interface.
  • the value of maximum overall absorption Pmax generally fluctuates between 2KW/h and 6KW/h. It is understood that, in accordance with a variation not illustrated, the definition of the value of maximum overall absorption Pmax can be adjusted also by the user via an interface integrated in the induction hob 2 and/or in the electric oven 3.
  • Regulation of the cooking functions of the induction hob 2 entails switching to cooking levels that do not exceed the operating limit L.
  • the power management device 4 can regulate the operating functions also of other appliances on the basis of an absorption priority level assigned to each appliance.
  • the power management device 4 can also regulate the function of the dishwasher by setting it to pause mode, so as not to interfere with the cooking level desired by the user.
  • the power management device 4 is integrated in a control device 8 of the induction hob 2.
  • the control device 8 of the induction hob 2 therefore comprises the power management device 4 and a function management module 9, which receives limitation signals from the power management device 4.
  • the power management device 4 receives the data on the operating status of the electric oven 3 from a control device 10 of the electric oven 3.
  • the communication between the control device 10 of the electric oven 3 and the control device 8 of the induction hob 2 is via a communication BUS 11.
  • the BUS 11 uses a LIN communication protocol.
  • the power management device 4 interrogates the control device 10 of the electric oven 3 at a predetermined frequency (generally in the order of milliseconds) about its operating state.
  • the electric oven 3 replies to the interrogations from the power management device 4 with a value of maximum current power absorption PO associated with the current cooking function.
  • the electric oven 3 provides its own maximum absorbable power level PO associated with the current cooking function.
  • the power management device 4 interrupts operation of the induction hob 2 or forces operation at very low power. This avoids excessively high operating temperature values.
  • the power management device 4 is not active.
  • the electric oven 3 can provide the current power absorption level associated with the current cooking function instead of the maximum level, to reduce the limitations of the induction hob 2 only to situations in which it is actually necessary. Said solution, however, could require an increase in the interrogation frequency of the electric oven 3 to avoid delays in managing the limitation of the induction hob 2 and would also require an evaluation of the current power variation of the electric oven 3 to avoid continuous fluctuations in the cooking functions of the induction hob 2.
  • the electric oven 3 provides only the current cooking function and the power management device 4 determines the absorption level associated with the current cooking function of the electric oven 3 on the basis of a stored data library.
  • the communication between the power management device 4 and the control device 10 of the electric oven 3 is via wireless mode.
  • FIG 3 illustrates a variation of the present invention in accordance with which the power management device 4 is integrated in the control device 10 of the electric oven 3 and sends limitation signals L to the control device 8 of the induction hob 2.
  • control device 8 of the induction hob 2 interrogates the control device 10 of the electric oven 3 at a predetermined frequency (generally in the order of milliseconds) about the required limitation level.
  • the control device 10 of the electric oven 3 replies to the interrogations by the control device 8 of the induction hob 2 with a limitation value L calculated as described previously on the basis of the maximum current absorption value PO of the electric oven 3.
  • the power management device 4 is not interrogated and does not send limitation signals L.
