Definitions

  • the present invention relates to a refrigerating appliance, in particular a household refrigerating appliance, with an engine room arranged under the carcass.
  • the body To prevent moisture from precipitating on the outside of the refrigerated body, the body must be designed so that its surface temperature never goes below the dew point. This requires either a sufficient thickness of the insulation layer of the body or, in places that can not be sufficiently isolated, especially in the area between a front of the body and the door of the device, an additional heating of the vulnerable surface areas.
  • the omission of the back wall condenser makes it possible to set up a refrigeration device with the machine room arranged under the carcass very close to a building or furniture wall. If this wall is itself good heat insulating, it contributes to the insulation of the refrigerator, with the result that the temperature in the gap between the rear wall of the device and the building or furniture wall can fall below the dew point. So moisture in the gap can condense, which does not evaporate or at best very slowly due to the narrowness of the gap. In the long term, this may result in damage to the device, the wall or adjacent furniture. The same problem arises, even without the wall in front of the device is good heat insulating when the device is placed in a warm environment with high humidity, especially in tropical climates.
  • the object of the present invention is to provide a refrigerator with a body and a machine room arranged under the body, in which the risk of precipitation of condensation on the back of the device or one of these back wall opposite is eliminated.
  • the object is achieved by having in a refrigerator with a body and an under the body engine room containing a compressor, a condenser and a fan and having a front inlet and at least one outlet for cooling air, a downstream of the fan overpressure area of the engine room adjacent to a rear wall of the engine room, in which at least one outlet is formed.
  • the forced air circulation of the fan forces a draft of air along the rear of the unit.
  • guide elements are preferably arranged in the outlet for deflecting the exiting air flow upwards.
  • the air guide elements are curved.
  • the at least one air outlet is elongated and extends in the width direction of the engine room.
  • the at least one air outlet is formed in a removable cover, which covers at least the overpressure region of the engine room largely.
  • a particularly favorable distribution of the device rear side over the cover flowing air stream results when a plurality of air outlets are provided on the cover distributed over the surface and have guide elements.
  • Each of these air outlets then has an air guide element for guiding the air flow upwards.
  • the rear wall of the engine room is also expediently flush with the rear side of the carcass.
  • the at least one air outlet on the rear wall of the machine room has an air outlet cross-sectional area which is smaller or at most equal to the air outlet cross-sectional area of the air outlet provided at the front of the machine room.
  • the sum of the air outlet cross-sectional areas is smaller or at most equal to the air outlet area of the air outlet provided at the front of the machine room.
  • the greater part of the cooling air flow exits at the front of the engine room.
  • the condenser is preferably located in a vacuum region of the engine room upstream of the fan so that the entire flow of cooling air is drawn across the condenser.
  • a vaporizer for condensed water inside the appliance is preferably exposed to the partial flow passing through the compressor.
  • the fan is expediently arranged in an intermediate wall between the vacuum region and the overpressure region of the machine room.
  • the engine room is at such a Built-in device preferably accommodates space saving in a base unit, which, when the device is mounted in a piece of furniture, engages through a cutout in a bottom plate of the furniture in the base area.
  • Subject of the invention is therefore also an arrangement of a kitchen furniture and built into a niche of the kitchen refrigerator of the type described above, in which the body is on a bottom plate of the furniture niche and dipping the base unit through a section of the bottom plate in the base region of the kitchen cabinet.
  • the cutout to the back of the niche is open.
  • the distance between the rear wall of the body and the back of the furniture recess is preferably less than 20 mm.
  • Fig. 1 shows a vertical section through a built-in household refrigeration appliance according to the invention and a furniture niche in which the device is received.
  • the refrigerator has a cuboid housing with a body 1 and a door 2, which define a heat-insulated storage chamber 3 in a conventional manner.
  • an evaporator 4 is embedded, which essentially cools the storage chamber 3, but which can also lead to a suitable ambient climate that the Temperature on the outside of the rear wall 5 drops below the dew point and can condense humidity.
  • a substantially cuboidal base unit 7 is mounted, the internal structure with respect to Fig. 2 respectively.
  • Fig. 3 will be explained in more detail.
  • a niche of a kitchen furniture, in which the device is mounted, has parallel to the cutting plane, not shown side walls and a bottom plate 8, on which the body 1 of the device rests.
  • the niche is bounded behind by a wall 25 of a building in front of which the furniture is placed; Alternatively, the wall 25 could also be part of the furniture itself.
  • the wall 25 and the rear wall 5 of the refrigerator limit a gap 26 with a maximum depth of 20 mm.
  • a base portion 10 below the bottom plate 8 is closed at the front by a bar 11 in which a vent 12 is recessed.
  • the bottom plate 8 is supported in a conventional manner by height-adjustable feet 13.
  • a recess 9 is cut in the bottom plate 8. The recess 9 is open towards a rear edge of the bottom plate 8, so that the gap 26 extends continuously through the recess 9 into the base region 10.
  • Fig. 2 shows in a schematic horizontal section the internal structure of the base unit 7 according to a first embodiment.
  • two large-area openings form an inlet 14 and an outlet 15 for cooling air.
  • a grid, fins or the like stretched over the openings prevent a user from inadvertently coming into contact with voltage-carrying components in the base unit 7.
  • the interior of the base unit 7 is divided by a running in the depth direction intermediate wall 16 into two chambers.
  • a fan 18 is arranged in one of a rear wall 17 of the base unit 7 adjacent region of the intermediate wall 16 in which a fan 18 is arranged.
  • a condenser 19 is in the suction side of Fan 18 located chamber 20 housed; the pressure-side chamber 21 includes a compressor 22.
  • the rear wall 17, which is formed in the present embodiment as a cover, is removable in order to access the chambers 20, 21 for assembly or repair purposes.
  • the part of the rear wall 17 which closes the chamber 20 is free of openings; in which the chamber 21 closing part openings are formed, preferably in the form of a plurality of parallel horizontal slots 23, wherein between the slots 23 left standing material of the rear wall 17 is deflected to widen the slots 23 and between them slanted slats 24 (see Fig. 1 ) to deflect the air exiting through the slots 23 upwards.
  • a portion of the circulated by the fan 18 cooling air is diverted after passing the condenser 19 and sweeps the back wall 17 and the flush adjoining the rear wall 5 of the body 1 up.
  • a collecting channel for condensing water on the evaporator 4 is formed at the bottom of the evaporator 4 in a conventional manner.
  • the water is discharged from the gutter into an evaporation tray 27 which is mounted on and heated by the evaporator 22. Since the ascending air in the gap 26 branches off before passing through the evaporation tray 27, steam does not get from there into the gap 26, but is blown through the outlet 15 and the ventilation opening 12 directly into the open.
  • Fig. 3 shows a modification of the base unit 7, in which the two chambers 20, 21 are arranged with the evaporator 19 and the compressor 22 in the depth direction one behind the other and a single outlet 28 is formed on the back of the base unit 7.
  • the entire cooling air flow is passed over the evaporator 19 and the compressor 22.
  • a predominant part of the exiting at the outlet 28 cooling air flows through cavities of the base portion 10 below the base unit 7 or laterally from this back to the front and exits at the vent opening 12 again.
  • Further guide walls 30 may be provided between the inlet 14 of the base unit and the vent opening 12 to ensure that used cooling air exits via the vent opening 12 and is not immediately sucked back into the inlet 14.
