Definitions

  • the present invention relates to a refrigerator with a cooled interior, from which a compartment is divided, which is less cooled than the rest of the interior and therefore usually has a slightly higher temperature.
  • a compartment is commonly referred to as a butter compartment, as it should offer the possibility of keeping butter spreadable, even if the rest of the interior is too cold for that.
  • a suitable temperature of the butter compartment has conventionally been readily achieved by placing it in a corner of the housing without direct thermal contact with an evaporator cooling the remainder of the interior space. Improvements in the insulation of refrigerators, however, lead to the fact that the achievable by such an exposed placement of the butter compartment temperature difference to the rest of the interior is reduced, the butter compartment is therefore too cold. The temperature difference is even lower when the refrigeration device is not installed in a heated living room, but in an unheated room. That is, efforts to build or operate refrigerators in an energy-efficient manner result in the problem that the temperature in the butter compartment becomes too low.
  • the object of the invention is to remedy this problem.
  • the object is achieved in that in a refrigerator with a surrounding a cooled interior heat-insulating housing, from the interior of a butter compartment is divided, the butter compartment is temperature controlled by a Peltier element.
  • the heating power of the Peltier element is suitably regulated to allow a flexible adaptation to user-desired temperatures of the butter compartment and the remaining interior, regardless of the ambient temperature in which the device is used.
  • a regulation may consist in that a user can specify a current intensity, with which the Peltier element is acted upon. 200700516
  • a Peltier element conventionally has a hot and a cold side. Of these, preferably one is in thermal contact with the butter compartment and the other is in thermal contact with a portion of the compartment other than the butter compartment. Thus, the heat supplied to the butter compartment is substantially removed from the other area of the interior space, thereby relieving a refrigerating machine provided in a conventional manner for cooling this remaining area.
  • the area other than the butter compartment is a compartment separated from the interior.
  • the Peltier element a total of three different tempered areas, namely the butter compartment, the partitioned chamber and a remaining main area of the interior, the chamber can reach even lower temperatures than the main area.
  • the Peltier element can be arranged in particular in the bottom of the butter compartment or in a flap closing the butter compartment (11).
  • FIG. 1 shows a schematic partial section through a refrigerator according to a first embodiment of the invention.
  • FIG. 2 shows a schematic section through a refrigeration device according to a second embodiment of the invention.
  • Fig. 1 shows a simplified section through the upper portion of a refrigerator housing with a body 1 and a door 2, which define an interior space 3. From the interior 3 a butter compartment 4 is divided in a conventional manner in an upper front corner.
  • the butter compartment 4 has a bottom 5 projecting from the door 2 into the interior 3 and a flap 6 comprising a vertical wall and a horizontal ceiling whose vertical wall rests on the floor 5 and 200700516
  • the flap 6 prevents air exchange between the interior of the butter compartment 4 and a main storage area 14, which occupies the rest of the interior space 3.
  • a Peltier element 8 is embedded in the bottom 5, a Peltier element 8 is embedded.
  • the Peltier element 8 is acted upon by a direct current from a user to a regulator, not shown, of adjustable intensity.
  • the current direction is set so that the upper side of the Peltier element 8 is warm and the lower one is cold. That is, the Peltier element 8 extracts heat from the main area of the inner space 3 to supply it to the butter compartment 4.
  • the DC power source to the operation of (not shown) based on the temperature of the interior space 3 thermostat controlled compressor coupled so that when a user adjusts the thermostat control warmer and thereby reduces the proportion of operating time of the compressor to the total operating time of the refrigerator, the Performance of the Peltier element 8 is reduced and excessive heating of the butter compartment 4 by the operation of the Peltier element 8 is avoided.
  • Fig. 2 shows a section through a refrigerator according to a second embodiment of the invention.
  • a butter compartment 4 in an upper, front corner of the interior 3 is divided.
  • an evaporator chamber 9 and between this and the butter compartment 4 is divided.
  • the freezer compartment 10 is closed by a flap 1 1, which is held with the door closed 2 between the bottom 5 of the butter compartment 4 and a bottom 12 of the freezer compartment 10.
  • Butter compartment 4 and freezer compartment 10 can be separated by seals 13 between the flap 1 1 and the bottom 5 and 12 largely airtight from an underlying main storage area 14.
  • a arranged in the flap 1 1 Peltier element 8 is as described above with reference to FIG. 1 can be acted upon with direct current to heat the butter compartment 4 and to cool the icebox 10.
  • the flap 1 1 here has the dual function of separating both the freezer compartment 10 and the butter compartment 4 from the main storage area 14, eliminates attached to the door flap 6 of the embodiment of Fig. 1, and it can with the door open on the 2 Contents of the butter compartment 4 are freely accessed without having to open another flap.
