Furthermore, the invention relates to a method for transmitting a measured variable which is detected by means of a measuring unit in a domestic appliance and is transmitted by a measuring control unit of the measuring unit via a data transmission channel to a main control unit of the domestic appliance which is isolated from the measuring unit.

  • the wireless transmission in particular the optocoupler
  • the requirements with regard to the galvanic separation is taken into account.
  • the known solutions in particular when using an optocoupler for data transmission, however, is to be considered as a disadvantage of the fact that such semiconductor devices are particularly susceptible to interference from interference pulses, as they occur for example by electrostatic discharges in household appliances.
  • a domestic appliance comprises a main control unit and a measuring unit isolated or galvanically isolated from the main control unit.
  • the measuring unit has a measuring control unit which is coupled to the main control unit via a data transmission channel. Via the data transmission channel, a measured variable that can be detected by the measuring unit, in particular by means of a sensor, can be transmitted to the main control unit.

  • the protective impedance ensures a potential separation between the measuring unit and the main control unit, whereby the requirements for operational safety is taken into account.
  • the measuring unit can also be referred to as a "measuring island".
  • the protective impedance is not assigned to the actual measuring circuit, in particular is not inserted in this, but the transmission of the data, the As a result of the measurement associated with the serving line, any impairment of the measurement itself by or due to the protective impedance is excluded.
  • the protective impedance has a high-pass filter coupling the measuring control unit to the main control unit. Then, the protective impedance has a reactive resistance, and interference pulses or DC currents occurring in the transmission channel can be suppressed.
  • the use of a high-pass filter thus enables the transmission of a high-frequency data signal, such as a digital signal, and also ensures the galvanic isolation or potential barrier between the measuring unit and the main control unit.
  • the high-pass filter can have a cutoff frequency greater than 50 Hz, preferably greater than 70 Hz, more preferably greater than 100 Hz. It is thus ensured that the cutoff frequency of the high-pass filter is sufficiently greater than the frequency of the noise voltage, that is, for example, the mains voltage.
  • the protective impedance preferably has a capacitance, by which the high-pass filtering is ensured.
  • the high-pass filter is provided in particular for the high-pass filter to have a capacitor which couples the measuring control unit to the main control unit or a multiplicity of capacitors connected in series. By the capacitor or the plurality of capacitors then the high-pass filter is formed.

  • the protective impedance has an effective resistance coupling the measuring control unit to the main control unit, via which a data signal characterizing the measured variable, in particular a digital signal, can be transmitted to the main control unit.
  • a parallel to the protective impedance extending reference line is provided, via which a reference signal parallel to the data signal, in particular to the digital signal, can be transmitted.
  • the protective impedance thus comprises one or more series-connected resistors which form the data transmission channel between the measuring control unit and the main control unit. In this way, a robust data transmission between the measuring unit and the main control unit with simultaneous isolation can be ensured without much effort.
  • the measuring unit is preferably designed to provide a DC voltage as a reference signal whose value is equal to the DC component of the data signal to be transmitted via the data transmission channel, in particular of the digital signal.

It has It is found to be particularly advantageous if a comparator is provided which is designed to generate an evaluation signal as a function of a difference between the data signal, in particular the digital signal, and the reference signal. Then, the main control unit is designed for evaluating the evaluation signal with regard to the measured variable.
  • the comparator can be connected upstream of the main control unit or integrated in this.
  • the comparator By using the comparator, by means of which the data signal transmitted via the data transmission channel and the reference signal are compared, it is possible to suppress disturbances in the mains voltage. Namely, the data signal transmitted via the transmission channel and the reference signal are attenuated by the protective impedance in such a way that the signal level generated by the interference voltage, such as the mains voltage, does not overdrive the comparator. Since the interference signal is always applied to both inputs of the comparator in the same polarity and only the difference between the signals is detected at the inputs of the comparator, the interference signal is suppressed. This suppression is also referred to as common-mode rejection.
  • the measuring unit can, for example, provide a serial digital signal or a bitstream, which is then transmitted via the data transmission channel as a data signal.
  • An advantage of this embodiment is that the transmission bandwidth ranges substantially from zero (DC) to the physical limits of the components, that is, the measurement control unit and the main control unit.
  • the domestic appliance can be designed as a domestic appliance for the care of laundry items, wherein the measuring unit is preferably designed for detecting a laundry-related size, in particular a conductance of items of laundry introduced into a drum of the domestic appliance.

  • the data transmission channel 10 has a high-pass filter 13 which is formed by a capacitor 14 coupling the measuring control unit 8 and the main control unit 9 and by an ohmic resistor 15.
  • the ohmic resistor 15 is connected to reference potential 4 of the circuit 3, so that the high-pass filter 13 is provided as RC high-pass.
  • the capacitor 14 is dimensioned such that the cutoff frequency of the high pass filter 13 is greater than 50 Hz, in particular greater than 100 Hz, as the frequency of the mains voltage to which the domestic appliance is connected. In this way it is achieved that only the digital signal 11, which correspondingly has a frequency greater than 50 Hz, and not the mains voltage can be transmitted via the data transmission channel 10.
  • the digital signal 11 is modulated or coded by means of the measurement control unit 8 in such a way that its DC component is zero.
  • the digital signal 11 is then transmitted via the data transmission channel 10, more precisely via the high-pass filter 13 and thus transmitted to the main control unit 9.
