Definitions

  • the invention relates to a refrigeration device, in particular a refrigerator or freezer with at least one cold space arranged within its heat-insulating housing and closable by a door, and to a unit space for accommodating device assemblies, such as a fan, condenser and compressor, within which at least one supply air is supplied - And an exhaust air port connected, designed as a flow channel for receiving the device assemblies, is provided, which is provided with upstream of the device assemblies on the supply side and these downstream sound-absorbing means and is supplied with cooling air by the fan.
  • device assemblies such as a fan, condenser and compressor
  • a refrigeration device which is equipped below its cold room serving as a useful space with a base, in the space bounded by its walls a U-shaped air duct arrangement is provided. This is used to hold the device units, such as fans, condensers and compressors, and has both a supply air and an exhaust air opening, each of which is equipped with sound-absorbing means for reducing the noise emanating from the fan and the compressor and propagating via the airway.
  • Such noise insulation measures often require technically complex additional equipment in the form of measuring devices, which is not inconsiderably reflected in the device costs, and, on the other hand, constantly recurring maintenance measures that depend on the device installation location. These, in turn, are often not feasible by technically less experienced people themselves, so that this group of people, in addition to the maintenance measure itself, is often provided with cost-intensive customer service.
  • the invention has for its object to propose soundproofing measures for a refrigerator according to the preamble of claim 1, which have a high functionality with a simple structure and at the same time adequate ventilation of the device aggregates is ensured for a long time.
  • the sound-absorbing means are formed predominantly from sound-absorbing material and are arranged at least in sections to form a labyrinth-like air path for the cooling air circulated by the fan, which is able to flow essentially uninhibited within the labyrinth-like air path.
  • the solution according to the invention avoids a flow through the sound-absorbing means and thus provides an almost flow-resistant sound insulation, on which there is almost no pressure loss in the cooling air flow which leads to congestion effects and thus to cooling losses.
  • in addition to complex devices which monitor the permeability of the sound-absorbing means there is also no need for constantly recurring maintenance measures.
  • it is possible through the solution according to the invention to vary the noise-reducing effect of sound insulation be it through appropriate choice of material or through a large number of rows of labyrinth sections, without any noticeable loss of cooling air performance, the sound-insulating effect also being effective through a variety of different labyrinth structures can influence.
  • the labyrinth-like airway is particularly versatile in terms of its structure and particularly easy to influence in terms of its sound-absorbing effectiveness if, according to a further advantageous embodiment of the object of the invention, it is provided that the labyrinthine Airway is essentially formed by the wall surfaces of mutually one behind the other at a distance from one another, along wall 20, 32 of the airway designed as flow channel 26, sound-absorbing individual elements, the mutually facing ends of which overlap.
  • the labyrinth-like airway is particularly simple and yet has sufficient sound-absorbing effectiveness if, according to a next advantageous embodiment of the object of the invention, it is provided that the labyrinth-like airway is formed by the walls of at least two mutually spaced, sound-absorbing individual elements, whose mutually facing ends overlap.
  • a particularly uniform flow cross section within the labyrinth-like airway can be achieved if, according to a further preferred embodiment of the object of the invention, it is provided that the walls of the individual elements forming the labyrinthine airway are arranged at a parallel distance from one another.
  • the sound-absorbing individual elements can be arranged particularly easily to form a labyrinth-like airway if, according to a further advantageous embodiment of the object of the invention, they are designed as cuboid shaped parts. Furthermore, this design of the individual elements makes it possible to integrate them into the construction technology for the assembly room with load-bearing functions.
  • a particularly space-saving structure for a labyrinth-like airway is obtained if it corresponds to another preferred embodiment of the object of the invention it is provided that the cuboid-shaped individual elements for forming the labyrinth-like airway are arranged substantially perpendicular to the walls of the flow channel.
  • the labyrinth-like airway is arranged at a distance from the supply air and exhaust air openings of the flow channel.
  • Such a measure ensures that the cooling air can enter a wide range via the supply air opening and that the exhaust air can also exit wide and unobstructed via the exhaust air opening.
  • the sound emanating from the noise sources such as the fan and compressor, is not attenuated immediately in front of a possible operator of the refrigerator, but in advance, so that this operator is not exposed to unnecessary noise levels.
  • a flow duct is particularly expedient if, according to a further advantageous embodiment of the object of the invention, it is provided that at least one side wall of the flow duct running along the flow direction of the cooling air is lined with sound-absorbing material in the region of the labyrinthine airway.
  • the flow channel has a U-shaped contour and its supply air section is separated from its exhaust air section by a sound-absorbing partition.
  • both the longitudinal side of the supply air and exhaust air ducts are equipped with the noise-reducing, sound-absorbing material in a single step.
  • the lower section of a kitchenette 10 is indicated schematically, which has a niche 11 for installing a built-in freezer 12.
  • This is equipped with a freezing space 14 which can be closed by a heat-insulated door 13 and which is heat-insulated in a conventional manner and which is cooled by the evaporator tier, which is not shown and is arranged at intervals one above the other.
  • drawer-like containers 15 serving for the storage of frozen goods can be introduced, which can be used if necessary by means of a handle (not specified) can be removed from the freezer compartment 14.
  • a device base 16 is provided below the freezer compartment 14, adjoining it, but thermally separated from it by the bottom of the freezer compartment 14.
  • the appliance base 16 has a base base 17, from the side edges of which are arranged toward the base of the freezer compartment 14, surrounding a base space.
  • the door 13 facing the front plinth wall is designed as a detachably held ventilation grille 18 with lattice-shaped divided air passage openings 19, while the remaining plinth walls are designed as a continuous wall train 20, which is molded onto the plinth floor 17 and in this way together with it in one piece Form molding, which is made for example from plastic injection molding.
  • the base space delimited by the ventilation grille 18 and the continuous wall line 20 serves as an aggregate space 21 for accommodating device assemblies, such as a condenser 22, a compressor 23 and a fan 24 arranged between the two in relation to the ventilation grille 18 in its rear area generates during its operation an air flow 25 (shown in dashed lines) which circulates in the direction of the arrow, so that the condenser 22 for cooling lies in the pressure-side section of the air flow 25, while the compressor 23 is swept by the suction-side section of the air flow 25 for its cooling.
  • a condenser 22 for cooling lies in the pressure-side section of the air flow 25
  • the compressor 23 is swept by the suction-side section of the air flow 25 for its cooling.
  • the air flow 25 is guided within the unit space 21 in a U-shaped flow channel 26 serving as an airway, within which is arranged in the rear area of the unit space 21, through the two legs of the U-profile connecting yoke formed channel section, the equipment units are arranged.
  • the two duct sections which serve as the exhaust air duct 27 and the supply air duct 28, are separated from each other in terms of flow technology by a duct partition 29 which is arranged essentially perpendicular to the ventilation grille 18 and which is formed from sound-resistant material at its end sections 30 and 31, while the intermediate section 32 consists of sound-absorbing material (e.g. open-cell foam).
  • the end section 31 is at a distance from the impeller diameter of the fan 24 opposite a wall web 33 made of sound-resistant material, which together with the end section 31 of the duct partition 29 saves an air passage for the air flow 25 sucked in by the fan 24.
  • the air flow 25 is guided both in the exhaust air duct 27 and in the supply air duct 28 in a labyrinth-like air path 34 (for the exhaust air duct 27, the representation of the air flow 25 has been omitted for the sake of clarity).
  • the labyrinth is formed from mutually spaced, sound-absorbing cuboid individual elements 35 which are arranged essentially perpendicular to the side walls delimiting the supply air duct 28 and the exhaust air duct 27.
  • the individual elements 35 are arranged within the supply air duct in such a way that their mutually facing ends 36 overlap and their wall surfaces 37 together on the overlapping ends 36 form the labyrinthine airway 34.
  • the arrangement of the individual elements 35 which are formed, for example, from open-pore foam and designed as molded parts, deflects the symbolically represented air flow 25 several times, the distances between the individual elements 35 being selected such that only a negligible pressure drop occurs in the air flow 25 within the labyrinthine air path 34.
  • the arrangement of the labyrinth-like airway 34 represents a sound path 38 for the sound waves emanating from the device assemblies, in particular from the compressor 23 and the fan 24 (symbolically represented by arrows for the exhaust air duct 27), on the basis of which the sound energy emanating from the device assemblies mentioned is repeated Reflection within the labyrinthine airway 34 on the sound-absorbing individual elements 35 is converted almost completely into thermal energy, so that only a small percentage of the original noise emission of the equipment units emerges from the unit space 21.
  • the reduction in noise emissions is additionally supported by the fact that the labyrinth-like airway 34 used for sound destruction is set back at a distance from the air outlet openings 19 arranged in the ventilation grille 18, in the case of the exhaust air duct 27 as exhaust air openings and in the case of the supply air duct 28 .
