Definitions

  • the invention relates to a refrigerator, in particular a refrigerator, with a compressor motor and a compressor motor compartment, which has an engine compartment wall.
  • the invention is based on the objective of designing a piece of refrigerated furniture, in particular a refrigerator, in a suitable, sound-reduced manner.
  • the capsule element Due to the fact that the capsule element is open towards the rear, and thus also the compressor motor is exposed towards the rear, there are nevertheless surprisingly favorable thermal conditions a without the sound absorption would be significantly affected. This is because the fact that refrigeration units of this type are placed with the compressor motor toward the wall is advantageously used.
  • the generally reverberant wall reflects sound waves emanating from the compressor motor on the exposed side back into the capsule element, which is also open to the wall, so that these sound waves are in turn largely dampened by the capsule element.
  • the above and below described subject is not limited to refrigerated cabinets.
  • the concept according to the invention can also be applied to other floor-standing devices, in particular furniture-standing devices with an electric motor that is similarly exposed to the outside.
  • the capsule element has steps which lead to a different distance from the engine compartment wall. In this way, the effects that can be achieved by the enclosed air cushion between the flexible, thin wall of the capsule element and the engine compartment wall can be optimized.
  • a special further development also provides that the capsule element extends laterally with a comparatively shallow depth to the compressor motor, but continues to open towards the rear of the refrigerated cabinet, preferably with an integral design. This is particularly important in that lateral emissions of the compressor motor, towards the side in which it is essentially exposed, meet the capsule element in reflection from a wall, in front of which, for example, the refrigeration cabinet is located, and are suitably absorbed or damped .
  • the capsule element is perforated.
  • the capsule element is dome-shaped in such a way that a substantial distance is formed between the capsule element and the compressor motor above the compressor motor and that an opening is formed in the capsule element in the region of the greatest distance to create a certain chimney effect.
  • a chimney draft effect can be achieved through the dome-like design described. In this way, an essential natural convection can be generated, which can optimize the heat dissipation.
  • the chimney formation can also extend relatively far upwards in the refrigeration cabinet, in order then to open up into the surroundings, which only improves the chimney draft.
  • a condensate drip tray is formed integrated in the capsule element.
  • a trough-like design is created in the capsule element, in which this condensed water can be collected.
  • the water collecting trough preferably extends essentially above the compressor motor.
  • FIG. 1 a Shown and described is first of all with reference to FIG. 1 a - only partially drawn - refrigerated cabinet 1 with a compressor motor 2 and a compressor motor chamber 4 (see, for example, FIG. 2).
  • the compressor motor compartment 4 is divided by a capsule element 5, which consists of closed-cell polyethylene foam.
  • the capsule element 5 is thin-walled, for example with a thickness of 2 mm.
  • the capsule element surrounds the compressor motor 2, as it were, like a shell, but at different distances, as can be seen in detail from the sectional views in FIGS. 5 to 7.
  • the distance to the engine compartment wall 3 is also different.
  • the capsule element 5 is designed to be open to a rear side of the refrigerator, to which rear side the compressor motor 2 is also detached in the capsule element 5.
  • a distance a on the back of the compressor motor 2 is chosen larger than a distance b on the top of the compressor motor 2.
  • the distance a corresponds approximately to the distance c on the underside of the compressor motor 2 with respect to the clear one Distance to an engine compartment capsule itself, regardless of the vibration damper 6 still arranged below the compressor motor 2 and the mounting rails 7.
  • the distance a on the rear side of the compressor motor 2 is selected differently, specifically in such a way that it is in corner areas 8, 9 of the compressor motor 2 down to a system on the compressor motor 2.
  • the capsule element 5 While one side 10 of the compressor motor 2, where in particular cable connections and the like are located, the capsule element 5 is guided very close - at 11 - past the compressor motor 2, and is approximately rectangular in shape, an opposite one is angled with respect to the rear opening plane E. , provided at an angle alpha given extension of the capsule elements 5. This leads to a suitable absorption not only of the sound waves radiated directly from the compressor motor 2, but also to those sound waves which are reflected on a - not shown - reverberant wall, against which the refrigerator is placed in the installed state. Of particular importance in this context is the lateral extension, which is provided overall with reference number 12, which extends beyond the actual compressor engine compartment 4.
  • this embodiment is optimized in such a way that suitable absorption of sound waves reflected in this direction can also take place.
  • the capsule element 5 is provided with holes 13 which provide a direct connection to air spaces 14, 15 between the capsule element 5 and the engine compartment wall 2. It is not shown in detail that these air spaces 14 can also be subdivided by suitable bead formation, but can each be provided with a plurality of holes 13, so that overall a modified Helmholtz resonator results, as has already been described in detail above .
  • a depth t here is substantially less than a depth t 'in the area of the actual compressor motor space 4.
  • a water collecting trough 16 is formed on the upper side of the compressor motor 2, integrated in the capsule element 5. This is done simply by forming a bead, a circumferential U-bead 17 in the capsule element 5. Condensation or the like can drip into the water collecting trough 16, for example, through an opening 18 in the engine compartment wall 3 from above. The extent of the water collecting trough 16 can be much larger than shown in the drawing.
