Definitions

  • the invention relates to a refrigerator and / or freezer with a base part in which the condenser blown by a fan and the compressor are accommodated and which is provided with suction and discharge openings.
  • the condenser housed in the flat, box-shaped base part must be blown by a fan, to generate the necessary air circulation to dissipate the heat.
  • the fan is arranged behind a suction opening covered by a front panel and directly blows on the condenser. The swirled blown air then traverses the interior of the base part in an unordered form and seeks its way to the blow-out opening, which is also clad by the front panel.
  • the air sucked in by the fan is therefore not optimally used for cooling the condenser and the compressor as well as other heat-generating parts.
  • Another disadvantage of the known devices is that the compressor and the fan produce disturbing noises, which can additionally be amplified by the base part and the attached container, which form resonance bodies, so that they do not meet the increased requirements for quiet operation .
  • the object of the invention is therefore to provide a refrigerator and / or freezer of the type mentioned, which is characterized by quiet operation with effective removal of heat from the condenser and compressor.
  • this object is achieved in a refrigerator and / or freezer of the generic type in that the fan, the condenser and the compressor are held in a closed air duct, the suction and discharge openings of which are closed by porous and / or grid-like disks.
  • the noise-generating unit parts namely the fan and the compressor, are, as it were, encapsulated in the air duct forming a closed housing, so that the airborne sound is trapped in the air duct and cannot penetrate to the outside in an impairing manner.
  • the suction and exhaust openings of the air duct are closed by porous and / or lattice-like disks, which contribute to a substantial noise insulation of airborne noise.
  • the arrangement of the fan, the condenser and the compressor result in an orderly routing of the air sucked in by the fan, so that the greatest possible cooling of the unit parts is achieved with the lowest fan output and the lowest possible circulating air flow can be used.
  • the panes closing the intake and exhaust openings should be selected in such a way that they offer as little resistance as possible with the greatest possible sound insulation of the air passing through.
  • the panes can consist of mats made of textile material, possibly with metal mesh inserts. They are conveniently easily interchangeable so that they can be replaced quickly if their porosity should be reduced by clogging with dust and dirt.
  • the suction and discharge openings are expediently located on a base side, and these are provided with closing doors on which the panes or mats are held.
  • the doors can be integrated uniformly into the front panel, with holders, for example guides or clamping parts, being provided on the back for the mats, which rest on the edges of the intake and exhaust openings when the doors are closed.
  • a device for measuring the overpressure is expediently provided in the air duct, which, when the overpressure rises, indicates that the air permeability of the mats has decreased to such an extent that they have to be replaced.
  • a further sound reduction can be achieved in that the side walls of the air duct are lined with the air sound absorbing material, which is known in different forms.
  • the electrical duct is also expedient in the air duct Control of the device, in particular the power part of the control, arranged so that they are cooled by the fan air flow.
  • the air duct can consist of a U-shaped, tube-like tube. It can also be formed by a box which is provided with a separating web part to form two parallel branches, one side of the box being provided with the suction and exhaust openings.
  • the condenser expediently consists of a one-piece, meandering tube, the coldest part of which faces the fan.
  • the pipe sections of the meandering bent pipe which run vertically from top to bottom can stand "web on gap”.
  • the light source for the device lighting can be arranged in the air duct, light guides leading to the parts to be illuminated being provided, which can consist of glass fibers or plastic lines. With this arrangement, the heat-generating light source is also cooled by the valve air flow.
  • the air duct is expediently supported on the base of the base box by elastic elements.
  • the compressor and / or the condenser can be connected to the wall of the air duct via elastic elements, so that these parts that generate vibrations and noise are additionally decoupled.
  • the compressor and / or the condenser are expediently supported on the bottom of the air duct by elastic elements.
  • the air duct is open at the top and is closed by the bottom of the body of the cooling container placed on the base part.
  • the bottom area of the container body can be provided with a mat that seals the air duct.
  • the cooling container housing is articulated to an upper side edge of the base box or frame.
  • This configuration enables quick and easy access to the unit parts arranged in the base part for the purpose of maintenance and repair.
  • the lines leading to the evaporator are designed to be correspondingly long and flexible.
  • the base box with the air duct held in it can be inserted between the side walls of the cabinet, which are extended beyond the bottom of the cooling container.
  • This configuration also enables good accessibility to the unit parts encapsulated in the air duct housing. In order to enable this insertion and removal, the refrigerant lines must be long and flexible.
  • the base part 1 itself consists of a flat box in a rectangular shape, which is closed on its sides and on the back by wall elements or boards and is additionally provided with a base plate and a cover plate.
  • the base plate is supported on the floor via foot pieces.
  • the front of the base box 1 can be closed by pivoting flaps 3, 4, on the inside of which filter mats 5, 6 are fastened interchangeably.
  • a U-shaped air duct is held in the base part 1. This consists of interconnected plastic or sheet metal shells.
  • a fan motor 7 with fan screw 8 is held in the air duct 2 directly behind the filter mat 6.
  • the fan screw 8 is arranged in a narrow cross section of the air duct, so that it works with high efficiency.
  • the fan then blows the condenser, which is arranged in the lower branch of the air duct, and consists of a one-piece, meandering tube, the tube sections running perpendicularly from top to bottom being “web on gap”.
  • the condenser 9 is connected to the compressor 8 such that the coldest part faces the fan 7, 8. However, the arrangement can also be reversed.
  • the compressor 10 is held in the branch of the air duct parallel to the condenser.
  • the refrigerant lines then lead from the compressor 10 to the evaporator in a manner not shown.
  • the power electronics 11 and the central light source 12 are arranged, from which light guides then lead to the parts to be illuminated.
  • the entire box-shaped air duct 2 is supported on the base of the base part 1 by elastic elements 13. These can be damped springs or rubber blocks or blocks made of elastomeric material.
  • the air duct 2 is supported on the floor only via the damping elements 13 and otherwise has no further contact with the walls of the box-shaped base part 1.
  • the condenser and also the compressor 10 are in turn supported on the bottom of the air duct 2 via elastic damping elements 15.
  • the filter mats 5, 6 are held on the flaps or doors 3, 4 in such a way that they grip like plugs in the suction and discharge openings of the air duct.
