Definitions

  • the invention relates to a refrigerator according to the preamble of claim 1.
  • Refrigerators with at least two superposed cooling compartments, one of which serves as a freezer, are well known.
  • a refrigerator of this kind is for example in the CH 695 463 disclosed.
  • each of the refrigerated compartments operated at different temperatures is provided with a corresponding evaporator forming part of a refrigeration circuit equipped with a compressor and a condenser.
  • the present invention has been based on the task to make the refrigerator of the type mentioned as a so-called no-frost refrigerator.
  • the cooling compartments are cooled by means of a cooling air circulated via a common evaporator by means of a fan.
  • the evaporator is housed in a separate evaporator chamber.
  • the communication paths between the evaporator chamber and the individual cooling compartments can be closed and the air circulates in the evaporator chamber alone, the defrosting process can be performed quickly, especially when the air in the evaporator chamber is temporarily heated.
  • a refrigerator 1 with two superposed cooling compartments 2, 3 are shown, of which the lower serves as a freezer compartment 2.
  • the cooling compartments 2, 3 are each provided with a door 2a, 3a closable.
  • the evaporator 10 forms part of a equipped with a compressor and a condenser cooling circuit, which are not shown in detail.
  • the intended for the cooling air is fed from above into the evaporator chamber 5. It thus flows through an outer part 5a of the evaporator chamber 5 down and then from below through the evaporator 10 therethrough.
  • a number of inlet openings 12 is provided, via which the cooling air is introduced into the freezer compartment 2, wherein the circulating with the aid of a fan not shown in the freezer compartment 2 cooling air in turn over a number supplied from the bottom of the partition wall 11 outlet openings 13 from below into the evaporator 10.
  • the temperature in the freezer compartment 2 is measured and regulated so that the inlet openings 12 are closed when a setpoint value is reached, preferably with the aid of an indicated controllable slide 14.
  • connection openings 18 are provided which lead to the upper cooling compartment 3, and on the other hand a number of return openings 17 for the circulating in the upper cooling compartment 3 cooling air available.
  • connection and return openings 18, 17 are preferably closed by means of a slider.
  • the communication paths between the evaporator chamber 5 and the freezer 2 and the cooling compartment 3 (with more than two refrigerators to all refrigerators ), the inlet openings 12 and the outlet openings 13 in the freezer compartment 2 are closed by means of slides 14, 16, so that in this no air circulation takes place, and also the circulation of air in the upper compartment 3 is suppressed.
  • connection openings 18 to the upper cooling compartment 3 are connected by a connecting line 20 to the return openings 17 and the air circulation is thus limited within the evaporator chamber 5, in which the air through the outer part 5a down, through the evaporator 10th through to the top and via the connecting line 20 again flows from above into the outer part 5a.
  • controllable closing members 18 ', 17' such as slides, containing, which cause the desired air circulation.
  • the arrangement of the evaporator chamber 5 on the rear wall 4 of the freezer compartment 2 is not absolutely necessary; it could also be adjacent to one of its side walls or even to one of the walls of the upper one Refrigerator compartment 3 be assigned.
  • the solution shown allows a particularly advantageous air flow.
  • the means for closing and opening communication paths between the evaporator chamber 5 and the individual refrigerators may be different than slides, e.g. be designed as flaps or the like.
