Definitions

  • the present invention relates to a household refrigerator of the built-in type, comprising a refrigerated compartment and a basement containing a condenser, a fan and a compressor, said basement having an open rear face facing a house wall where the refrigerator is adapted to be installed.
  • household refrigerator as used in this description and the appended claims is intended to include refrigerators and freezers.
  • Refrigerators of the above type have the advantage of maximising the volume of the appliance since the condenser is placed in the basement and not between the wall and the rear face of the refrigerator.
  • the condenser and the fan are placed in a bottom niche together with the compressor.
  • the fan creates an airflow directed towards the front wall of the refrigerator or towards an interspace between the house wall and the rear wall of the refrigerators.
  • a sort of "short-circuit" between cold and warm air is avoided, and cooling air is forced in a sort of "chimney” defined by the above interspace so that also a convection effect is added to the forced air flow.
  • the drawback of this solution is that the furniture containing the built-in refrigerator may need some adaptation work in order to create a proper cooling airflow pattern.
  • Such usual adaptation is needed especially in certain countries where the wooden door of the kitchen furniture abuts the front edge of the furniture cavity containing the built-in refrigerator.
  • the cooling air has to flow under the furniture (i.e. between the floor and the furniture) and cannot be sucked by the fan which therefore is substantially useless.
  • the installation of the refrigerator is not properly made (i.e. the aperture in the furniture is not cut before the installation) the refrigerator will work with a condenser at a much higher temperature than designed, with problems of higher energy demand and possibility of compressor failures.
  • Purpose of the present invention is to provide a household refrigerator of the built-in type in which there is no need of adapting the furniture in order to have a proper flow of cooling air.
  • Another purpose of the present invention is to provide a built-in refrigerator in which the cooling of the condenser and compressor is improved, so that energy saving is obtained too.
  • a refrigerator in which the rear face of the basement is provided with sealing means adapted to cooperate with the house wall in order to define an air suction mouth upstream the condenser.
  • a partition wall is preferably provided between the condenser and the compressor so as to define a U-shaped channel or duct and in order to cool the compressor downstream the condenser.
  • FIG 1 With reference to figure 1, with 10 is indicated a built-in refrigerator installed in a standard cavity C defined by a rear house wall W and side furniture walls P (figure 3).
  • the built-in refrigerator 10 has an upper refrigeration compartment 10a and a lower freezer compartment 10b.
  • a space K is defined between the refrigerator and a bottom wall B of the furniture.
  • the wooden door D of the furniture closes the space K, and therefore the air can flow only under the bottom wall B of the furniture for reaching the fan 12.
  • the fan 12, a condenser 14 and a compressor 16 are contained in a niche 18 defined in the basement of the refrigerator 10.
  • the niche 18 has an open rear portion 18a facing the wall W where the refrigerator is installed.
  • a partition wall 20 whose function is to create an U-shaped air flow around the partition 20.
  • the air taken from the external ambient is forced to pass through the condenser 14 and the compressor 16, as there is still a potential for heat transfer with the compressor, since it is at a higher temperature.
  • a preferable path with a low pressure drop is created for the air going out after passing through condenser 14 and compressor 16, without going back to the fan inlet region.
  • the above desired flow pattern is obtained by sealing the inlet region of the fan 12. This is realised by adding to an upper edge of the rear portion 18a of the niche 18 and to the rear edge of the partition wall 20 a L-shaped rubber gasket 22 which abuts against the wall W on which the refrigerator 10 is placed.
  • Other kinds of gasket can be used, for instance made by foamed polypropilene or similar foamed polymeric material.
  • the use of the gasket 22 avoids air recirculation between high pressure and low pressure areas as this means a very good air flow and performance.
  • the gasket 22 is fixed to a corresponding L-shaped seat 22a (figure 2) by means of adhesive or known fastening means.
  • the air pushed by the fan 12 passes through the condenser 14 first, then through the compressor 16 and finally escapes from the compressor niche 18 towards a space H defined between the rear wall of the refrigerator 10 and the house wall W.
  • the arrows show the main air flow pattern where air is sucked mainly from a bottom front portion 21 of the refrigerator 10 and is discharged in the interpsace H that acts like a chimney.
