  • the insulation of the refrigerator and / or freezer door in built-in appliances is carried out correspondingly strong in order to avoid condensation.
  • the door insulation must be performed so strong that would result in a relatively large loss of content in the device.
  • Another way to improve insulation is the use of vacuum panels.
  • vacuum panels have the disadvantage that they are relatively expensive and in the case of the least leaks lose their good insulating properties in the long term.
  • the present invention is therefore the object of developing a refrigerator and / or freezer of the type mentioned in such a way that the occurrence of condensate reliably prevented or the probability of the occurrence of condensate is reliably reduced.
  • a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that a heating device is provided on or in the region of the door or flap and / or on or in the region of the device outer wall. With such "anti-condensation heating", the occurrence of condensate can be effectively prevented.
  • the door or flap has an outer wall and that the heating device is arranged on the inside and / or outside.
  • the heater can be provided in series use or be designed as a retrofit kit.
  • kits that consists of said heater or at least this. It is conceivable, for example, later on the Ger- door or door or between the appliance door and furniture door to apply the kit or the heater.
  • the heater is conceivable, for example, to perform the heater as a film heater, which is glued to the outside of the door or door.
  • the type of heating is arbitrary. The same applies to their attachment.
  • a preferred embodiment of the invention lies in a foil heater with a small thickness. If a device door and a furniture door are provided, this results in particular in the advantage that a minimum distance can be realized between the two doors.
  • the heating device is located on the inside of the door or flap, provision can be made for the heating device to be foamed in or adjacent to the foaming.
  • the use of the heater is not limited to the door or flap of the device. It is conceivable that the condensation on the housing of the device should be prevented. Thus, it can be provided that the heating device is arranged on the inside and / or on the outside of the device outer wall. In this case, it may be useful to provide one or more heating devices there as well.
  • the heating power of the heater used in the invention may be relatively low, since this only has the task to ensure that the Dew point at the desired installation conditions is preferably not fallen below.
  • the heating device is an electric heater.
  • the use of a film heater is provided, which requires a small mounting space.
  • a self-adhesive heater or a self-adhesive film heater is used, but any other form of heating or electric heating is used.
  • the device is in communication with a furniture door or flap and that the heating device is arranged in the region between the furniture door or flap and the appliance door or flap.
  • the heater can be arranged on the appliance door or flap or on the furniture door or flap. It is also conceivable to arrange the heater in the space between two doors or flaps. It is crucial that the heating device is designed in such a way that said condensate formation in the region in question is completely or substantially prevented.

  • the device has a control or regulating device for operating the heater or a receptacle for such a control or regulating device. It is advantageous if a mounting option of the control or regulating device is already taken into account on the device side.
  • the control or regulating device may be designed such that it switches on the heating device as soon as the device is switched on. In this case, the heater will run with the unit turned on.
  • the heating power must be matched to the door or flap surface, on the one hand to ensure that the formation of condensate does not occur or only to a minor extent and on the other hand to avoid an unacceptably high heating of the device.
  • a temperature sensor is provided for determining a temperature actual value, and that the control or regulating device is designed such that it operates the heater such that the actual temperature value with the due to a comparison of the actual temperature value with a temperature setpoint or with a temperature setpoint range Temperature setpoint or is within the temperature setpoint range. It is conceivable, for example, that the temperature sensor is arranged on the outside of the door or flap or, for example, measures the temperature in the area between a furniture door or flap and the appliance door or flap. The temperature sensor can of course also be arranged elsewhere. It is essential that by means of the measured actual temperature conclusions on the probability of the occurrence of condensate can be drawn, so that the heater can be controlled accordingly.
