Definitions

  • the present invention relates to a refrigerator and / or freezer with at least one fan, at least one compressor and at least one condenser.
  • condenser and compressor / s are connected in series.
  • the arrangement may be variable, e.g. in the form of a series connection of compressor, fan and condenser or in the form of a series connection of condenser, fan and compressor.
  • the first variant has the disadvantage that the discharged compressor heat is supplied by means of the fan to the condenser, while in the second variant, the discharged condenser heat is supplied to the compressor.
  • the disadvantage that the waste heat of one or more components is performed on another component to be cooled also.
  • the WO 2008/000811 A1 discloses a refrigerator, the compressor and its condenser are acted upon by a fan with air.
  • a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that a refrigerator and / or freezer has at least one fan, at least one compressor and at least one condenser, wherein the or the fans are arranged such that this compressor and condenser act in parallel with air.
  • a fan is arranged such that this compressor and condenser act in parallel with air.
  • the fan, the compressor and the condenser are designed or arranged as a base unit or as a ceiling unit.
  • it proves to be an advantage due to the available space, e.g. only be able to act on both compressor / condenser and condenser with cooling air by means of a fan.
  • One or more filters may be provided in front of the fan. This results in the advantage that the contamination prevents, for example, the condenser / reduced can be. This in turn helps to maintain the full performance of the condenser and thus helps to increase the efficiency of the refrigerator and / or freezer.
  • the compressor and condenser are at least partially separated from one another with regard to the air flow guide. By separating an improved or targeted air flow can be achieved.
  • an air guiding device which at least partially separates the air flow from or to the compressor and from or to the liquefier.
  • Such an air guide device can also already have corresponding recesses or Aftrufthese for the compressors, the fan or the condenser.
  • the air guiding device has an air flow guide for the compressor and an air flow guide for the condenser and at least one bypass or connecting channel, which connects the two air flow guides together.
  • a connecting channel the distribution of the air flow used for cooling can be adjusted specifically.
  • the condenser and at least one compressor are located downstream of the fan.
  • connection channel is located downstream of the fan. This makes it possible in a particularly simple manner, a part of the air flow for the application of the other components, e.g. branch off the compressors.
  • the air flow guides each have an inlet and an outlet, which are arranged such that the air flow through the inlets and through the outlets takes place in parallel.
  • the inlets and outlets are arranged such that the air flow from the inlets to the outlets covers a curved region, for example an angular range of 180 °.
  • Other cooling areas such as the air duct by 90 °, etc. are conceivable. This results in an improved space utilization, which is particularly advantageous in a version with base or ceiling unit.
  • the connecting channel has an actuator for throughput adjustment.
  • this actuator for example manually or automatically, depending on the actual cooling air requirement, the distribution of the air flow can be changed, since the branched off via the bypass or connection channel air flow can be adjusted. Further details and advantages will be explained with reference to an embodiment described in the drawing.
  • the single figure shows schematically the base of a refrigerator and freezer according to the invention with base unit, which has an air guide device 10.
  • base unit which has an air guide device 10.
  • inlet openings 20 and 30 and outlet openings 22 and 32 are provided.
  • the inlet and outlet ports 20 and 22 belong to the air flow guide 24 of the condenser 2
  • the inlet and outlet ports 30 and 32 belong to the air flow guide 34 of the compressors 5 and 6.
  • a filter 4 Downstream of the inlet port 20, a filter 4 is mounted to reduce the pollution of the condenser 2 and to maintain the performance.
  • the entire entering through the inlet opening 20 cool ambient air is purified by the filter 4 in particular from the dust.
  • the filter is arranged obliquely to the inlet direction and upstream of the fan 3 in order to provide the largest possible filter surface available. This allows a longer life of the filter. 4
  • the fan 3 Downstream of the filter 4, the fan 3 is mounted, which acts on the condenser 2 with a primary air flow with cool ambient air 26 and sucks them via the inlet opening 20.
  • the air 28 exits via the outlet opening 22 again, without being guided by the compressors 5 and 6.
  • the compressors 5 and 6, on the one hand, and the condenser 2, on the other hand are not influenced by their waste heat, since the waste heat produced is dissipated separately.
  • the air flow guides 24 and 34 guide the air through 180 °, so that the inlet and outlet direction of the air flow is parallel.
  • the air flow guide 24 of the condenser 2 lies on the inner web. In principle, two or even more than two air flow guides or webs can be provided, on which one or more components to be cooled are located. This allows a compact air flow guide.
