Definitions

  • the invention relates to a method for carrying out a hygiene program for a laundry treatment device, a control device and a laundry treatment device.
  • the object of the invention is to create an improved method for carrying out a hygiene program for a laundry treatment appliance, an improved control device and an improved laundry treatment appliance.
  • this object is achieved by a method for carrying out a hygiene program for a laundry treatment appliance, a control device and a laundry treatment appliance with the features of the main claims.
  • a laundry treatment device can be understood to mean a device in which laundry, for example textiles, can be treated.
  • this can be a washing machine, a washer-dryer or a tumble dryer.
  • the treatment of laundry can be understood to mean, for example, washing or drying or carrying out the hygiene program described here.
  • the laundry treatment appliance When the laundry treatment appliance is in operation, the laundry can be arranged in a laundry treatment space formed by the drum and treated using the process air.
  • the heat pump can be understood as a known device in which the components are functionally connected to one another in order to heat and dehumidify the process air flowing through. For example, the process air can first flow through an evaporator and then through a condenser.
  • a refrigerant can be or can be arranged in a refrigerant circuit of the heat pump.
  • the refrigerant can be vaporized in the evaporator using moist process air and condensed in the condenser using the dehumidified process air.
  • a compressor and a throttle can also be arranged in the refrigerant circuit.
  • the heat pump device can thus be used to take in the humid process air, for example from a laundry treatment room, to cool it and dry it, to heat it up again and to release it again.
  • the laundry treatment device includes a heating unit that can be operated electrically, for example, and is designed to heat the process air independently of the heat pump.
  • the process air driven by the process air fan, can flow in a circuit both through the heat pump and through the heating unit and can be heated either by the heat pump or by the heating unit or by both at the same time.
  • the switching on and switching off of the heat pump and heating unit can be controlled by the control device.
  • the heated air can then be used to blow the drum of the laundry treating appliance and to heat laundry arranged in the drum, for example during the hygiene program.
  • the hygiene program can be used, for example, to hygienically prepare laundry that has already been washed and at least partially dried. This can be advantageous, for example, when laundry has not been removed directly from the washing machine after a wash cycle, but has been left in the closed drum for a period of time, for example a few hours.
  • the laundry can be moistened and heated using the method presented here in order to reduce the germs that have formed.
  • a germ reduction with increased air humidity or relative humidity of, for example, up to 85% and at the same time an increased temperature of, for example, up to 75° C. can contribute to the reduction of germs.
  • Humidity can be achieved by spraying the nebulized water into the drum.
  • Nebulized water can be understood to mean water present in the form of droplets. Depending on the spray device used, such droplets can have a larger or smaller diameter. Smaller droplets can help achieve the desired humidity level more quickly.
  • the heat pump can be switched off and the desired hygiene temperature can be maintained alone during the hygiene phase that follows the heating-up phase until the end of the hygiene program the heating unit can be maintained.
  • the process air can be heated up and high humidity can be generated. Under these conditions, germs can be actively reduced.
  • Optimum conditions in terms of temperature and humidity can be created when the electric heater is operated and the heat pump remains switched off.
  • the step of outputting the pump signal can occur before the steps of outputting the switch-on signal and the heating signal.
  • the pump can be switched on in a first step in order to moisten the dry laundry with finely nebulized water at the beginning of the hygiene program, which can be pumped out of a condensate tank and sprayed into the drum, for example.
  • the process air can then be heated so that the water in the drum can evaporate.
  • a combination of increased humidity with increased temperature enables optimal conditions for germ reduction.
  • the step of outputting the pump signal can take place after the steps of outputting the switch-on signal and the heating signal.
  • the process air and the laundry arranged with it in the drum can be heated to a predetermined temperature before it can be moistened by the pump as a result of the pump signal.
  • the humidity can be kept higher and less water is required. For example, at a temperature of 20° C. and a relative humidity of, for example, 65%, cotton can have a residual laundry moisture content of 0%.
  • cotton can have a residual laundry moisture content of up to -3%, which means that the laundry can be overdried, so to speak.
  • cotton can have a residual laundry moisture content of 3% at a temperature of 20 °C and a relative humidity of, for example, 80%.
  • cotton can have a residual moisture content of the laundry of 1% and when heated to 85 °C a residual moisture content of the laundry of -1%.
  • With a relative humidity of 95%, for example, and heating to a temperature of 20°C cotton can have a residual moisture content of the laundry of over 10%.
  • cotton can have a residual laundry moisture content of between 4 and 6%. Consequently, heating the laundry prior to wetting can reduce water uptake in the laundry.
  • the pump signal can be output when the temperature signal represents a predetermined preheating temperature.
  • the preheating temperature can correspond to the hygiene temperature.
  • the laundry arranged in the drum can be heated to a certain temperature, for example 65°C.
  • the temperature inside the drum can decrease again slightly, so that it can be heated again to the predetermined hygiene temperature in the subsequent step of outputting the switch-on signal.
  • this allows temperature and humidity to be optimally coordinated with one another, as a result of which water can be saved.
  • the method can have a step of outputting a reversing signal to an interface to a drive of the drum in order to bring about a reversing state of the drum.
  • the drum of the laundry treatment appliance can be designed as a reversible drum, as a result of which a rotation process in two directions can advantageously be possible.
  • driving the drum can cause a change in the direction of rotation.
  • Such a reversing state can be implemented in response to the reversing signal, for example.
  • the laundry can be moistened in the reversing state in order to advantageously achieve optimum moisture penetration of the laundry.
  • the predetermined hygienic temperature value can be at least 60°C.
  • the control device can use the temperature signal to continuously compare the current temperature in the drum with a stored temperature reference value in order to determine whether the desired hygiene temperature, for example 65° C., has been reached.
  • germs can be reduced by heating to over 60°C.
  • the predetermined hygienic humidity value can be at least 60%.
  • the control device can use the humidity signal to continuously compare the current humidity in the drum with a stored humidity reference value in order to determine whether the desired hygienic humidity, for example 65%, has been reached.
  • germs can be reduced at a humidity of over 60%.
  • the method can include a step of ending the hygiene program after a predetermined period of time, after the step of outputting the switch-off signal.
  • the control device can comprise a counter which can count down a predetermined period of time, for example 30 minutes, as a result of the step of issuing the switch-off signal and additionally or alternatively as a result of the step of issuing the pump switch-off signal.
  • a predetermined period of time for example 30 minutes
  • both the hygienic temperature and the hygienic air humidity can be maintained in the drum.
  • the hygiene program can be ended automatically after the time period has expired.
