Like this FIG. 2 shows, the air passes through the in FIG. 2 Right portion of the grid 10 shown in the base area, then flows over the compressor 50 and then flows through the fan 60. The air then passes through the condenser 70 back to the front of the device and then exits from the area shown on the left of the grid 10. Basically, a reverse flow is conceivable.
  • FIG. 3 shows in a perspective view of the base unit, wherein the same or functionally identical elements with the same reference numerals as in FIGS. 1 and 2 are provided.

  • the condenser 70 On the top of the condenser 70 is the thawing water tray 80th
  • the fan 60 In the flow direction downstream of the condenser 70 is the fan 60. From this, the air flows to the compressor 50 and leaves the base unit on the back of the device. Basically, a reverse air flow is possible to the effect that the air flows through the base area from back to front.
  • FIG. 5 shows in a sectional view of the rear portion of the base region with the water valve 100 arranged above, the lower-mounted refrigerant valve 110 and with the designated by the reference numeral 60 fan.
  • the reference numeral 200 designates the cooled interior, which is delimited by an inner container or by a foaming of the base region.
  • the reference numeral 120 denotes the back cover of the niche.
  • the niche wall is not designed as a closed wall, but has a backdrop-shaped opening 122. This has the function, on the one hand to dissipate the air to the rear of the base area and on the other hand, the function of exerting a sound-insulating effect.
  • FIG. 6 shows a comparable arrangement in which the lower portion of the recess wall 120 is straight and the upper portion is angled and covers the lower portion, so that also results in an opening 112, but mirror-symmetrical to that according to FIG. 5 ,
  • FIG. 7 a further embodiment of the device according to the invention is shown.
  • This figure refers to the front area of the device.
  • the air flow L is marked, which enters at the front, if necessary, through a grid in the base area.
  • various configurations and functions such as handles, attachment of the thawing tray, etc., are possible.
  • Reference numeral 200 again indicates the refrigerated interior, and reference numeral 300 denotes the door.
  • FIG. 7 further shows, located in the lower end of the door a sound insulating material 400, which also serves to reduce the noise of the socket assembly to the outside.
  • the sound-absorbing material is located on the front side of the front inlet area of the base unit.

  • Conceivable is a fixed fixation z. B. by gluing or by automated spot welding / soldering. In the case of a removable version, fastening by screws, rivets or notches is possible.
  • the decoupled version can be achieved for example by springs or elastic walls / "net”.
  • the design of the subframe may, for example, be such that receptacles for one or more of the components: valves, compressor, fan, evaporation tray, sound insulation (labyrinths, mats), cables / tubes, carrying handles, rollers are formed.
  • the subframe or the base bottom for example, be designed such that it achieves a separation of suction and pressure side, for example by a labyrinth seal, as for example in FIG. 8 represented by the reference numeral 500.

  • One advantage is that the air flow is less deflected, resulting in noise advantages.
  • condensation water tray 80 and the condenser 70 are preassembled as a module and, for example, are inserted as such from below into the socket assembly or its housing.
  • a holder 700 for the condenser 70 is hooked to the base assembly or to the housing 1000 and that the condensation water tray 80 is screwed to the holder 700, as is apparent from FIGS. 11a to c evident.

  • the condensation water tray 80 can be removed separately, for example by loosening screws without condenser, ie the condenser 70 remains hanging (see. FIG. 11c) , Subsequently, the condenser 70 may also be removed, if necessary.
  • An advantage of this approach is the removability and a mounting advantage.
  • rear cover plate 120 of the niche 40 which forms the rear base portion, for example, plastic, sheet metal, reinforced Cardboard or consist of a combination of the aforementioned materials.
  • Conceivable is a fixed attachment, for example by gluing or a removable version z.

  • B. has one or more openings for a water valve, which brings with it the advantage that the customer does not have to open anything. It can also have one or more openings for the air, resulting in a dynamically ventilated niche.
  • a reinforcement by reinforcing parts in the form of beads, honeycomb structure, etc. is also conceivable.
  • the device termination that is, the surface to the subframe with recordings of components such. B. valves, fan, etc. provided.
  • the surface to the device carrier may be covered with low emissivity film, which has the advantage of achieving a low emissivity for heat flow optimization.
  • the condenser or the evaporation tray can be made removable, so that a correspondingly simple handling is achieved in the case of customer service.
  • the front grille which may serve as an air inlet or as an air outlet or both, may be removable for cleaning, for example. It is conceivable to arrange an air filter therein.
  • the air filter can be arranged by sprayed recordings on the subframe or on the said grid.
  • front grids 10 it is conceivable for front grids 10 to be displaced in the direction of the condenser 70 in order to make the return or gap S between the door 300 and the grille 10 as large as possible for the purpose of a large air cross section. This results, for example, from FIG. 12 ,
  • a dust filter 11 may be integrated, for example clipped, glued, molded etc.
