Definitions

  • the present invention relates to electronic circuits for domestic electrical appliances, the main field of use of the invention being that of washing machines.
  • This invention relates in particular to an electronic card equipped with a controller for three-phase asynchronous motor or a chopper for universal motor.
  • the two programmer and motor control functions cannot be referenced to the same potentials.
  • the electronic programmer card is normally referenced to the neutral potential to be able to control the load control triacs, whereas the motor control card is placed after a rectifying diode bridge and is therefore referenced to the neutral potential but also to the phase, alternately.
  • the present invention aims to overcome these drawbacks by proposing a simple and cost-effective solution based on the general principle of shifting the optical communication insulation, so that the two functions are referenced to the same potential.
  • the main subject of the invention is a controller for three-phase asynchronous electric motor or for chopper for universal motor, comprising power units such as triacs or relays, for controlling loads, characterized in that the power units other than the relays are controlled via an insulation means, by at least one microcontroller acting as electronic programmer and, via a control, the motor control function, said microcontroller being referenced to the “zero” potential of a rectification and filtering block supplying power to the motor.
  • the inventive idea is to shift the optical insulation of the “programmer—motor” controln communication to the load control triacs, and to reference the two functions to the “zero” potential of the diode bridge of the rectification block.
  • the insulation means can be an optical means of the optotriac or optocoupler type, or even an electromagnetic means of the relay or transformer type. In the case of the optocouplers, it is essential to provide an insulated power supply for the triac control power.
  • the low voltage power needed for the microcontrollers can be supplied by one and the same power supply.
  • the microcontroller power supply can thus be very simple and also power a user interface card.
  • the solution provided by the present invention proposes a simple and cost-effective device for controlling motors, in particular three-phase asynchronous motor, which represents a considerable asset in an industrial and commercial context where there is a need for rapid adaptation to new requirements.
  • FIG. 1 is a block diagram of a current solution, with electrical insulation at communication level
  • FIG. 2 is a block diagram of the solution that is the subject of the present invention, with optically insulated load control;
  • FIG. 3 is a partial schematic view of an exemplary embodiment of the invention applied to a washing machine.
  • FIG. 1 illustrates the state of the art explained above. It represents a three-phase asynchronous electric motor 1 and its controller, and power units 2 , such as triacs or relays, for load control.
  • the power units 2 are controlled by a first microcontroller 4 forming an electronic programmer.
  • a second microcontroller 5 handles control of the motor 1 via a control 6 .
  • a low voltage power supply 9 powers the first microcontroller 4 , the second microcontroller 5 being powered by a separate power supply.
  • Optocouplers 3 in this case insulate the communication between the first microcontroller 4 referenced to the neutral potential and the second microcontroller 5 referenced to the “zero” potential of a rectification and filtering block 7 which powers the motor 1 via an inverter 8 .
  • FIG. 2 in which the elements that correspond to those described previously are denoted by the same numeric references, indicates the principle of the solution proposed by the present invention.
  • the triace 2 a are controlled by the first microcontroller 4 , constituting an electronic programmer, via an optotriac 13 ; the relays 2 b , insulated by themselves, are directly controlled by the first microcontroller 4 .
  • a second microcontroller 5 controls the motor 1 via a control 6 .
  • the two microcontrollers 4 and 5 are referenced to the “zero” potential of a rectification and filtering block 7 which powers the motor 1 via an inverter 8 .
  • the low voltage power needed for the two microcontrollers 4 and 5 is supplied by one and the same low voltage power supply 9 , which also powers a user interface card (not shown).
  • FIG. 3 is a partial diagrammatic view of an exemplary embodiment applied to a washing machine, to control an electric motor 1 driving the drum of this washing machine rotation-wise.
  • This figure represents four load control assemblies 2 a , 2 b , 2 c and 2 d made up of triacs, for the hot water 10 a and cold water 10 b solenoid valves, a drain pump 10 c and a product dispenser 10 d .
  • Each load control assembly is insulated by an optotriac 13 a , 13 b , 13 c , 13 d.
