Definitions

  • the present invention refers to a circuit for an electric appliance.
  • the power consumption due to the stand-by current is relatively low (about 1 Watt) but it can result in a considerable consumption in connection with a large number of electric appliances and with the number of hours each appliance is kept in a stand-by condition during its whole operative life.
  • the easiest solution to the problem of avoiding stand-by power consumption in an electric appliance consists in providing the appliance electronic circuit a main switch that allows the appliance to be powered only when the user turns said switch on.
  • Patent No. US 7,045,917 discloses a circuit arrangement for an electric appliance having a control device and a power supply unit connected to an electric current supply connector for providing controlled functional units of the electrical appliance with current.
  • the electrical power supply connector is provided with a piezo switch that cuts off the power supply unit from the electric current supply connector.
  • the piezo switch which is open in a non-activated state, is connected with a power semiconductor circuit which, when the piezo switch is operated, connects the control device for activation with the electric power supply connector.
  • a drawback of the circuit arrangement described in US 7,045,917 consists in the presence of a semiconductor circuit that does not grant an absolute electrical isolation of the power supply unit from the electric current supply connector when the piezo switch is in an open state. This can cause an electrical current consumption even when the appliance is in a stand-by condition.
  • the aim of the present invention is therefore to solve the noted problems and thus providing a circuit for an electric appliance that eliminates the current consumption when the appliance is in a stand-by condition.
  • Another object of the present invention is to provide a circuit for an electric appliance that allows the latter to be promptly activated without the need of maintaining its electronic circuits constantly powered.
  • a further object of the invention is to simplify known circuit arrangement for electric appliances reducing the number of circuit components.
  • Figure 1 shows schematically a circuit for an electric appliance according to the invention
  • the circuit according to the invention comprises a pair of connectors 1 and 2 powering a primary side 3 of a transformer 4.
  • Said transformer 4 provides controlled functional units of an electrical appliance with current.
  • One of the connectors 1, 2, is provided with a switch 5 that allows the user to activate and cut off the primary side 3 of the transformer 4 from the connectors 1, 2.
  • a secondary side 8 of the transformer 4 is electrically connected to a control device 6 that supervises all the appliance operations including the supply of electrical current.
  • a relay 7, arranged in parallel with the switch 5, is connected and activated by the control device 6 in order to by-pass the switch 5.
  • the switch 5 is a monostable switch, i.e. a switch having a single stable state and a unstable state that requires constant energy to sustain.
  • the stable state is represented by the open position of the switch 5 while the unstable state consists in its closed position.
  • the control device 6 can activate again the relay 7 that interrupts the by-pass of the switch 5. Since the latter is in its stable position, i.e. in an open state, the power supply is interrupted.
  • the switch 5 can be in the form or a push button or, in case the electrical appliance has a door with a locking mechanism, as in case of a washing machine or an oven, such switch 5 can be integrated in the locking mechanism such that, when the user opens the appliance door acting on the locking means, the control device is activated and the electric appliance is brought in a "ready to be used" state. It is also possible to provide the switch 5 and the relay 7 integrated in a single electrical component that can be activated both manually by a user both mechanically and/or electronically by the feedback of the control device 6.
  • circuit according to the invention allows to eliminate any electrical power consumption in an appliance when the latter is switched off.
