Definitions

  • the present invention relates to a refrigeration device.
  • slotted silencers are also known in the prior art. Slotted silencers are used where noise from air intake or air discharge should be reduced.
  • a slotted silencer consists of, for example, a rectangular or cylindrical housing with Schallabsorptionseinbauten (scenes). The scenes are provided with sound absorber material (for example, mineral fibers). The medium to be damped flows through the spaces between the scenes. The sound waves penetrate into the sound absorbing material of the scenes and their energy is reduced there by friction, i. the sound is muffled.
  • a refrigeration device has a ventilation duct on which a silencer with sound absorption internals (slotted), which are provided with sound absorber material, for silencing the medium in the ventilation duct.
  • the muffler is therefore designed as a backdrop muffler.
  • the medium to be damped for example, the supply or exhaust air from a compressor of the refrigerant circuit of the refrigerator, flows through the interspaces of the scenes.
  • the sound waves penetrate into the sound absorber material of the scenes and their energy is reduced there by friction, ie the sound is attenuated.
  • the sound emissions of the Refrigerating appliance for example, resulting from the operation of compressors or fans can be effectively reduced.
  • a refrigeration cycle of the refrigeration device comprises, for example, a compressor for compressing refrigerant vapor, a condenser downstream of the compressor for condensing the refrigerant vapor, and an evaporator downstream of the condenser and upstream of the compressor for vaporizing the liquefied refrigerant.
  • the compressor is like the evaporator for heat transfer between the supplied air and the fluid set up.
  • a refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance which is used for household purposes or possibly also in the gastronomy sector, and in particular for storing food and / or drinks in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge freezer, a freezer or a wine storage cabinet.
  • the ventilation duct is an air inlet and / or air outlet for exchanging air with an evaporator and / or a compressor of the refrigerant circuit of the refrigeration appliance.
  • the silencer in the form of a silencer attachment can be arranged detachably on the refrigeration device.
  • This embodiment makes the use of the silencer on the refrigeration device more flexible. A retrofit of the silencer on the refrigerator is possible. Depending on the noise emission requirements for the refrigeration device, corresponding variants of the refrigeration device can be realized cost-effectively with and without silencer. Furthermore, the use of different silencers on a standardized refrigeration device is made possible according to the sound attenuation requirements.
  • the sound absorption fittings are designed plate-shaped.
  • the plates can then be arranged individually according to the spatial conditions or the sound input into the muffler on the muffler. This can the sound attenuation can be optimized according to the situation.
  • the plates can be flat, for example. This results in a sound reflection on the plates defined with respect to the direction. Similar to a resonance muffler, good sound attenuation values can be achieved with plates arranged opposite each other.
  • the plate-shaped Schallabsorptionseinbauten are arranged, for example, maze-like nested. As a result, a good sound attenuation can be achieved by a multiple sound reflection at the different plates.
  • the plate-shaped Schallabsorptionseinbauten are arranged for example at an oblique angle to each other. In this case, at a reduced flow resistance for the air through the muffler at the same time a good sound attenuation can be achieved.
  • the plates are employed, for example, at an angle of 20 to 70 degrees to each other.
  • the sound absorber material comprises microfibers.
  • the microfibers allow a high sound absorption capacity. They are fast drying, which prevents mold formation in the refrigeration unit.
  • the sound absorber material for example, small holes, in particular with a diameter of 0.2-2.0 mm have. By injecting the sound waves into the holes, the radiated sound energy is reduced.
  • the sound absorber material has, for example, a layer thickness of 1 to 20 mm.
  • the refrigeration device has a pedestal, in which the silencer is integrated.
  • the base offers additional sound insulation for the silencer and sound sources arranged thereon.
  • the silencer has a dimensionally stable outer casing in which the sound absorption internals are arranged.
  • the muffler can be mounted as a self-supporting module on the refrigerator.
  • the outer housing and / or the Schallabsorptionseinbauten are made for example of plastic, in particular polyethylene or polypropylene. In the injection molding process, complex shapes can be realized cost-effectively.
  • the outer housing can also be made in one piece with at least one of the Schallabsorptionseinbauten, whereby the manufacturing process is simplified.
  • FIG. 1 shows a schematic representation of a refrigerator 1 according to a first embodiment.
  • the focus here is on a arranged on the refrigerator 1 silencer 5 with Schallabsorptionseinbauten 7.
  • the rest of the refrigerator 1 runs contourless shown in the background.
  • the muffler 5 has sound absorption mounts 7 provided with sound absorbing material 9.
  • the sound absorption material 9 is formed in this embodiment as a nonwoven with microfibers. This makes it easy to shape and adapt to the geometry of the sound absorption fixtures 7.
  • the sound absorption fixtures 7 are realized in this embodiment as plates which extend vertically in the image.
  • a ventilation duct 3 extends between the sound absorption fixtures 7. Sound in the air in the ventilation duct penetrates during operation into the sound absorption material 9 of the sound absorption fittings 7 and loses energy. The noise emissions are thereby reduced. That way you can For example, noise emissions to fans or the compressor of the refrigerator can be reduced.
  • FIG. 2 shows a schematic representation of the refrigeration device 1 according to a second embodiment.
  • a dimensionally stable housing 17 of the muffler 5 which receives the Schallabsorptionseinbauten 7.
  • the housing 17 in this embodiment has two openings, that is an air inlet 11 and an air outlet 13.
  • Flow arrows 19 symbolize the inflow of air into the muffler 5 through the air inlet 11 and the outflow of the air from the muffler 5 through the air outlet 13
  • Housing 17 allows a one-piece installation of the muffler 5 in the refrigerator 1 and provides an additional sound shield.
  • FIG. 3 shows a schematic representation of a muffler 5 of a refrigerator 1 according to one embodiment.
  • the muffler 5 here has a housing 17 with a substantially cuboid shape with bevelled edges.
  • the silencer 5 can be installed as a module for soundproofing in a refrigeration device.
  • FIG. 4 shows a schematic representation of the muffler 5 according to the embodiment of FIG. 3 ,
  • the housing 17 is designed in two parts in this embodiment and shown here open. This gives an insight into the interior of the muffler 5.
  • the sound absorption internals 7 with the sound absorption material 9 can be seen here.
  • the sound absorption internals 7 divide the interior of the housing 5 into individual chambers through which the medium to be damped flows.
  • sound absorption material 9 here is a fleece used.
