Definitions

  • the present invention relates to a refrigerator such as a refrigerator having a housing enclosing an interior and a fan unit mounted in the interior.
  • a fan unit can e.g. serve to intensify an air flow over a heat exchanger surface, so as to improve the cooling effect of the heat exchanger, or to equalize the temperature distribution in this by mixing the air of the interior.
  • such a fan unit is arranged in the upper region of the interior so that an air flow generated by it flows along a rear wall of the interior, wherein the air flow sweeps over a arranged on the rear wall of the interior evaporator.
  • the air flow is cooled, and the now cooled air can get into individual cooling compartments depending on the division of the interior.
  • a mounted in a corner formed by the rear wall and ceiling of the interior fan unit which has a fan as a radial fan.
  • the axis of the fan is arranged perpendicular to the rear wall, so that a parallel to the rear wall extending air flow is generated.
  • a fan impeller of the fan is spaced from the rear wall, and a gap between the impeller and the rear wall is used to accommodate a motor driving the impeller. This makes it possible to suck air in the immediate vicinity of the ceiling in the fan unit, however, the generated air flow has a width of the gap corresponding distance from the rear wall.
  • the fan is an axial fan and is arranged at a ceiling of the interior of a rear wall of the interior spaced by a gap and set up is to blow against the back wall.
  • the arrangement of the fan on the ceiling the air can be optimally absorbed even from the top and thus the warmest area in the interior.
  • the gap can be generated in a low-loss manner along the rear wall of the first horizontally oriented air flow generated by the fan To divert the interior.
  • the width of the gap corresponds to the radius of curvature of the rounding.
  • the gap is bounded on two sides by side walls.
  • the side walls thus limit the air flow in its width and direct it in the desired direction.
  • each side wall is continuously against the ceiling and the rear wall. This prevents air from leaking and swirling unintentionally on the sides of the fan assembly, thus providing greater airflow efficiency.
  • the fan assembly comprises a housing which separates the fan from a useful area of the interior. The housing hides the fan and also forms a design element. The fan can thus be used uniformly in a variety of different types of refrigerators, and an adaptation to the particular type of refrigerator can be made exclusively through the housing.
  • an air inlet opening of the fan assembly is bounded by a ceiling of the interior and of the housing of the fan unit.
  • an air outlet opening of the fan assembly is bounded by a rear wall of the interior and of the housing of the fan unit.
  • the air flow may flow down directly along the rear wall of the interior space.
  • a gap is formed between the rear wall and a rear edge of a refrigerated goods carrier.
  • the refrigerator according to the invention offers particular advantages in that through the guidance of the air flow along the back wall of the interior, condensation of an evaporator arranged in the rear wall can be prevented. Due to the compact design of the fan unit, the volume of the interior is not unnecessarily reduced. In addition, a higher efficiency can be achieved by means of a low-voltage axial fan than with centrifugal fans, as has hitherto been customary used in refrigerators, thereby the energy efficiency of the refrigerator can be improved.
