Definitions

  • the invention relates to a cooling device according to the preamble of the first claim.
  • a heat conduction device in the form of a metal sheet is assigned to support the defrosting process in the area of connecting lines between an evaporator assigned to the freezer compartment and an evaporator assigned to the normal refrigerator compartment; that is in thermal contact with the connecting lines and is otherwise arranged within the normal refrigerator compartment.
  • the heat-conducting sheet absorbs heat from the surroundings and releases it to the section of the evaporator which is generally made in one piece and which tends to freeze and which receives the connecting line.
  • heat is also conducted into the area of the connecting lines if icing does not occur in the area of the connecting lines at relatively high temperatures in the normal cooling compartment.
  • the invention has for its object to take measures in a cooling device according to the preamble of the first claim, by which an effective heat supply to the connecting lines is then possible, if there is actually a risk of frost or iron.
  • the heat transfer from the heat-conducting element to the connecting lines can be interrupted or reduced, the temperature of the connecting lines being taken as the control criterion.
  • a contact surface is connected to the connecting lines, which can be brought into contact with a separate heat-conducting element.
  • the heat-conducting element is preferably designed as a sheet which is guided through the insulation of the housing to the outside. This makes it possible to supply heat regardless of the temperature in the normal refrigerator compartment. It is also avoided in this way that a reduced defrosting power is supplied to the then particularly cold and prone to icing connecting lines at low temperatures in the normal cooling compartment and thus decreasing heat supply via the heat conduction device.
  • a freezer compartment 3 with a freezer compartment evaporator 4 in the upper part, while a normal cooling compartment 5, which is arranged underneath and is separated by the thermal insulation 2 Normal cooling compartment evaporator 6 is arranged.
  • the freezer compartment evaporator 4 and the normal refrigerator compartment evaporator 6 form a structural unit and are connected to one another via a connecting web 8 provided with refrigerant lines 7.
  • the refrigerant lines 7 are guided through the thermal insulation 2 separating the freezer compartment 3 from the normal refrigerator compartment 5.
  • the powered compressor in the refrigerant circuit of the refrigerating machine flows through the connecting lines 7 conveyed refrigerant from the freezer evaporator 4 to the normal refrigerating compartment evaporator 6 and from there back to the circuit board of the Tiefkühlfachverdam p fers 4.
  • the inflowing from the freezer evaporator 4 refrigerant in this case has such a low temperature that on the connecting lines 7 at the point of entry into the normal refrigeration compartment 5, precipitation or ice formation can occur due to the precipitation of atmospheric humidity.
  • a heat-conducting carrier 8 is connected to the connecting lines 7, in particular in the section entering the normal cooling compartment 5.
  • the carrier 8 is designed to be bendable and carries at its free end a contact surface 9 which is opposite a counter-contact surface 10 at a spatial distance.
  • the mating contact surface 10 is part of a heat-conducting element 11, which is led out of the housing through the insulation 2 and in particular runs parallel to a condenser 12 of the refrigerant circuit provided on the rear side.
  • the carrier 8 can be designed as a bimetallic element, the decreasing Temperature adjusted its free end with the contact surface 9 to the mating contact surface 10. This creates a heat coupling device, the heat transfer is changeable.
  • the heat-conducting element 11 is preferably designed as a sheet metal, the part protruding into the normal cooling compartment 5 being kept small in order to avoid undesired supply of heat into the normal cooling compartment 5.
  • the carrier 8 can also be adjusted by a temperature-controlled pressure cell and then only needs to consist of elastic, good heat-conducting material. It is also possible to actuate the carrier 8 by means of an electromechanical or electromagnetic adjustment device which always makes contact with the contact surfaces 9, 10 when the drive motor of the refrigerator is stopped.
  • the heat-conducting element 11 can be connected at its end protruding into the normal cooling compartment 5 to a bimetal strip which, at a relatively high temperature in the region of the connecting lines 7, is only in linear contact with the connecting lines or a contact surface connected thereto and with decreasing temperature in increasing surface contact occurs with the contact surface.
  • a bimetal strip which, at a relatively high temperature in the region of the connecting lines 7, is only in linear contact with the connecting lines or a contact surface connected thereto and with decreasing temperature in increasing surface contact occurs with the contact surface.
