Definitions

  • the invention relates to a method for operating a household refrigerator with at least one refrigerator compartment, which is assigned a controlled coolable no-frost evaporator and a fan that can be driven independently and which is separated by a partition from a freezer compartment.
  • the invention also relates to a household refrigerator or refrigerator, having at least one cooling compartment to which a no-frost evaporator and a fan are assigned, and a control device which is set up to cool from the no-frost evaporator and operate the fan .
  • the invention is particularly advantageous applicable to side-by-side refrigerators.
  • Double cooling devices which have a cooling compartment and a freezing compartment arranged laterally next to one another, which are separated from one another by a partition ("middle wall") (so-called “side-by-side” cooling devices).
  • a known problem with such double cooling devices is an accumulation of moisture in the cooling compartment (also referred to as a cooling space) in the area of the partition.
  • No-Frost cooling devices are known in which a fan blows cold air from an evaporator into the cooling compartment during a cooling phase.
  • the devices are designed in such a way that the air is returned to the evaporator as a cycle.
  • the warmer air from the refrigerated compartment condenses, with the condensate primarily condensing as frost on the cooling fins of the evaporator.
  • a heater defrosts the cooling fins at set time intervals, whereupon the frozen water present there thaws, exits the device as water via a channel and ends up in an evaporation container. Since the fan does not run during the defrosting phase, the refrigerator compartment remains cooled.
  • the no-frost technology not only prevents the cooling fins from permanently icing up, but the relative humidity in the cooling compartment also drops, so that almost no more layers of frost / ice form.
  • a known method for dehumidification consists in activating or switching on the fan for a certain period of time without there being a request to cool down the cooling compartment (in which the compressor is running and refrigerant is cooling the evaporator). This is also known as "compartment ventilation".
  • the compressor or the supply of the cooling compartment evaporator remains switched off or is operated independently of it.
  • the humid specialist air is circulated and passed through the even colder evaporator, while it falls below the condensation water temperature and therefore condenses out on the evaporator.
  • compartment ventilation is even disadvantageous. Because the air then condenses at the other, cooler point, so that the moisture is shifted from the evaporator to this other point.
  • the probability that another part of the refrigerator compartment is colder than the evaporator or the temperature in the refrigerator compartment (“Fachtempera ture”) increases if there is no longer a requirement for cooling the refrigerator compartment (“compartment cooling”), as the evaporator progresses Time is heated by the compartment ventilation.
  • the thicker insulation of the outer walls of the refrigerator also means that less heat from the outside enters the refrigerator compartment, which is positive in terms of energy, but increases the non-requirement time even further.
  • the object is achieved by a method for operating a household refrigerator with at least one cooling compartment, which is assigned a controlled coolable no-frost evaporator and a fan that can be driven independently thereof and which is separated from a freezer compartment by a partition
  • a cooling process for cooling the no-frost evaporator is carried out, in which the fan is switched off or the fan remains switched off.

This is particularly advantageous if the household refrigerator is also set up to carry out compartment ventilation.
  • the method includes that the no-frost evaporator is cooled without the refrigeration compartment being required to cool. This ensures that the no-frost evaporator is the coldest point of the refrigerated compartment or of an air section of air circulating in the refrigerated compartment at practically any time. In order not to unnecessarily cool the inside of the compartment too much, the no-frost evaporator is not cooled at the same time as the fan is switched on or activated.

  • a freezer compartment is understood to mean a coolable storage room of the household refrigerator whose set compartment temperature (“freezer compartment temperature”) can be set to a value below freezing point, for example to a value between -16 ° C and -24 ° C, but also above . Such a freezer compartment can also be referred to as a “frozen compartment”.
  • the fact that the no-frost evaporator can be cooled in a controlled manner includes in particular that it can be cooled in a targeted manner, for example by means of a control device.
  • the control can include setting a duration of the active cooling phase and possibly also a target temperature.
  • the fan can be switched on and off or activated and deactivated, for example by means of the control device. It is a further development that the fan is a variable-speed fan. It is a further development that the fan can be operated cyclically, in particular if only a small volume flow of the air moved by the fan is desired. The fan can also be referred to as a fan.
  • the evaporator cooling can in principle be started and / or ended in a time-controlled manner or after a given point in time and / or in a temperature-controlled manner.
  • the evaporator cooling is started at a predetermined point in time, the advantage is achieved that no sensor is required to start the cooling process, whereby a particularly inexpensive solution can be implemented, for example by programming the control device.
  • the starting time of the cooling process can be selected or specified in different ways, e.g. at one or more fixed times of the day, at specified time intervals since the end of the last compartment cooling and / or the last compartment ventilation of the cooling compartment, at a certain time interval before a planned compartment cooling and / or Compartment ventilation of the cooling compartment, etc.
  • the evaporator cooling after cooling is started over a predetermined period of time since the end of the last compartment cooling of the refrigerator compartment, as this allows particularly reliable, needs-based evaporator cooling to be achieved.
  • a suitable period of time for starting the evaporator cooling can be determined experimentally, for example.
  • “Compartment cooling” of the refrigerated compartment is understood to mean the activation or cooling of the no-frost evaporator while the fan is operating at the same time.
  • the compartment cooling can be triggered, for example, if a noticeable increase in the cooling compartment temperature has been determined above a corresponding limit value.
  • Compartment cooling can be requested, for example, after opening a door, after placing hot food, etc.
  • the compartment cooling of the refrigerator compartment can be carried out according to the no-frost method.
  • the freezer compartment can be compartment-cooled analogously to the refrigerator.
  • the predefined period of time for starting the evaporator cooling is a period of time that is dependent on an ambient temperature of the domestic refrigerator. This results in an even more reliable and energy-saving way of cooling the evaporator when the (evaporator) fan is switched off.
  • the ambient temperature can, for example, be measured using an ambient temperature sensor in the household refrigerator.
  • the no-frost evaporator is assigned a temperature sensor ("Ver evaporator temperature sensor”) for sensing a temperature (“evaporator temperature”) of the no-frost evaporator and the partition wall is assigned a further temperature sensor (“partition wall- Temperature sensor ”) for sensing a temperature (partition wall temperature”) is assigned to the partition wall and the evaporator cooling is started when the partition wall temperature is equal to or lower than the evaporator temperature.

  • a predefined period of time also referred to as “cooling period”
  • a predefined limit or threshold value e.g. 0.05 * a predefined limit or threshold value.
  • the cooling duration can be set, for example, so that the cooling process only needs to be carried out at longer time intervals without the use of a fan in order to avoid frequent starting of the compressor.
