Definitions

  • the present invention relates to a refrigerator and / or freezer with at least one refrigerant circuit having at least one condenser.
  • Your refrigerant circuit usually includes at least one compressor that compresses the refrigerant. From the compressor, the refrigerant passes into the condenser, where it gives off heat to the environment and thereby passes into the liquid state.
  • the refrigerant then passes through a throttle, in which its pressure is reduced, in the evaporator.
  • the refrigerant absorbs heat from the room to be cooled of the device, evaporates and finally returns to the compressor, where it is compressed again.
  • the condenser may be in the form of wire tube block liquefiers, spiral liquefiers, rolled wire tube liquefiers or else in other designs.
  • noises are based in particular on the fact that, for example, sheet metal or plastic parts of the device are set in vibration.
  • the present invention is therefore the object of developing a refrigerator and / or freezer of the type mentioned in such a way that such disturbing noises are reduced or completely prevented.
  • At least one absorber is provided, which is arranged such that it dampens or prevents vibrations of the condenser and / or that it dampens or prevents the transmission of vibrations from the condenser to other parts of the refrigerator and / or freezer. Any vibrations or vibrations on the condenser are thus at least partially absorbed or damped by the absorber, so that they can not or at least not undamped transferred to adjacent components.
  • the swinging of these components, such as sheet metal or plastic parts of the device can be reduced or completely prevented in this way. Accordingly, the aforementioned disturbing noises can be reduced or completely prevented.
  • the present invention relates to every possible embodiment of a condenser.
  • spiral tube condenser rolled wire tube condenser, wire tube block condenser, lamellar condenser or rolled-up wire tube condenser, etc. are conceivable.
  • the location of the liquefier is not limiting. It is conceivable, for example, to arrange the condenser on the rear of the device or in the base area of the device or in the ceiling area or in a lateral region of the device. If the condenser is arranged in the base area or in the ceiling area of the device, it is preferable to arrange it in the rear area of the device.
  • the absorber can be arranged so that it can be between the condenser and any other part of the refrigerator and / or freezer z.
  • the device base is located. It is preferably provided that the condenser is seated or stands on the absorber and / or that the absorber is on top of the condenser. In principle, it is also conceivable to arrange the absorber laterally, for example, in the event that the condenser is located on the rear wall.
  • the condenser has a plurality of condenser units and that the absorber is designed such that it has a tolerance compensation to compensate for the tolerances in the distance of the condenser units from each other.
  • the condenser consists of several towers of spiral tubes and that the absorber is designed so that it compensates for distance tolerances of the condenser towers from each other.
  • the Absorber according to this embodiment of the invention be designed so that one and the same absorber can be used for condenser, in which the distance of the condenser units from each other is not absolutely equal, but subject to variations.
  • one and the same absorber can be used for liquefiers whose liquefier units do not have an identical distance from one another or are not identical, but a distance which may vary from liquefier to liquefier, or other varying ones Have dimensions or dimensions.
  • the absorber is completely or partially made of an elastically or plastically deformable material.
  • Such an embodiment makes it possible to provide some variability in the arrangement or orientation of the condenser units on the absorber. This means that the condenser unit or the condenser does not always have to be arranged at the identical location, but that the absorber allows a certain variability with regard to the exact arrangement of the condenser or the condenser units.
  • the absorber may comprise one or more receptacles for receiving the condenser or condenser units or a section of the condenser or condenser units.
  • These receptacles can be embodied, for example, as projections which extend from a plane of the absorber. It is also conceivable that the absorber has recorded as a recess recordings.
  • the at least one receptacle can be round, preferably circular and flattened on at least one side, preferably on at least two sides Have areas. These flattened areas provide a way to ensure the above tolerance compensation.
  • the at least one receptacle has one or more ribs onto which the liquefier or a section of the servicer or the liquefier unit is plugged in the assembled state or with which it is connected.
  • these ribs which are preferably deformable, a compensation of diameter tolerances of the condenser or the condenser.
  • These ribs can also have the function of reliably holding the condenser or the condenser unit at the desired location of the absorber.
  • the at least one rib is arranged on the at least one receptacle. It may, for example, extend from its outer edge or, in the case of an exception made as a recess, from its wall.
  • a condenser shown here is a Spiralrohrvermillioner with four square towers 12.
  • any other arrangements such as an arrangement of the condenser towers 12 in the triangle, a version with, for example, five towers or more towers in a circle, etc. conceivable.
  • the condenser 10 has a supply line 14 for the refrigerant to be liquefied and a discharge line 16 for the liquefied refrigerant.
  • the four towers 12 of the liquefier 10 rest on an absorber 20.
  • This absorber can be formed, for example, by a plastic material or have such. Other vibration damping or absorbing materials are also included in the invention.
  • FIG. 3 shows, the absorber 20 on its side facing the towers 12 side projections 22, wherein in the embodiment shown here, a projection 22 is provided per condenser tower 12.
  • a projection 22 is provided per condenser tower 12.
  • the projections are realized in their plan view as circular images, of which two opposite sides are flattened.
  • the condenser units or towers 12 which in FIG. 2 with the reference symbols A and B and in FIG. 3 denoted by the reference numeral C, can be compensated by the absorber 20 and its projections 22.
  • the flattened areas are not identical for all projections 22.
  • the absorber 20 is according to FIG. 3 not only on the bottom of the condenser 10, but also on the top.
  • the absorber 20 on the top and bottom of the absorber 10 may be identical or different.
  • the projections 22 are not solid, but hollow inside.
  • This clamping not only has the advantage that the condenser 10 or its tower 12 is securely fixed, but also that the said tolerance compensation of the diameter of the condenser unit 12 is possible by the somewhat yielding material of the ribs.
  • the ribs 30 can thus be designed preferably elastically deformable or plastically deformable. Incidentally, this may also apply to the further material of the absorber 20 as well as to the projections 22 themselves.
  • the ribs 30 extend from the non-flattened sides, that is to say from the bent sides of the projections 22.
  • any other shape of the projections 22 is conceivable, such as an oval design, etc. Instead of a circular shape or partial circle shape of the projections 22.
  • FIG. 4 shows the lower end of several condenser towers 12 of a condenser 2, which are plugged onto the ribs 30 of the projections 22 and fixed there.
  • FIG. 3 It can be seen that in a central region of the absorber 20 is a projection 40 which is circular in the embodiment shown here. Adjacent to this projection, the outer sides of the plugged towers 12 of the condenser 10, so that the projection 40 serves as a further fixation of the condenser towers 12.
  • the absorber can be pre-assembled by the condenser supplier and thus also serves as a backup during delivery against bending of the individual towers 12.
  • the absorber 20 can result in significantly improved stackability and thus logistical advantages.
  • the actual material of the absorber 20 may differ from the material of the projections 22.
  • the invention also includes the case that the entire absorber 20 with projections 22 and ribs 30 and the projection 40 is made of the same material and preferably in one piece.
  • the materials are to be selected so that the part of the absorber, which is in communication with another part of the refrigerator or freezer, has the best possible vibration-absorbing properties and the projection 22 and the ribs 30 have properties that ensure a good fixation of the towers 12 of the condenser 10.
