Definitions

  • the present invention relates to a refrigeration device and in particular the discharge of condensate from a housing enclosed by a housing of the refrigerator.
  • condensing water which precipitates on the cold surfaces of an evaporator during operation of a refrigerator is conducted via a passage in a wall of the housing into an evaporation tray located outside the housing.
  • this evaporation tray is usually mounted on a compressor to use the waste heat of the compressor to improve the evaporation performance.
  • Devices are also known in which the evaporation tray is not on the compressor and in which other heat-releasing components such as condenser tubes are in close thermal contact with the evaporation tray to heat their contents and promote their evaporation ,
  • the evaporator In a refrigerator with a cold wall evaporator, the evaporator is usually mounted between an inner container and an insulating material layer surrounding the inner container, and a collecting channel is formed in the inner container at the foot of a cooled by the evaporator wall portion in which condensed water deposited on the wall portion can , A puncture emanating from the lowest point of this gutter may be directed vertically downwards to direct the condensation into an evaporation tray placed below the puncture.
  • This solution is particularly suitable for refrigerators with a single storage compartment or for the respective lowest storage compartment of a combination refrigerator.
  • a vertically downward piercing In order to dissipate condensation from an upper storage compartment of a combination refrigerator, a vertically downward piercing is usually unsuitable because the underlying storage compartment is in the way; In this case, it is customary to guide the puncture obliquely downwards out of the storage compartment to the rear of the device and to guide the condensation over a line running along the back of the device to the evaporation tray.
  • the evaporator In a no-frost refrigerator, the evaporator is usually housed in a compartment which is divided off in the upper region of an interior of a refrigerator. To condensation remove it from there, it is common to lead a hose from the evaporator chamber through the Dämmmaterial für the housing wall down to the evaporation tray.
  • a refrigeration device of this type is for example in JP 11 231 84U described.
  • the object of the present invention is to provide a refrigeration appliance construction which, by standardizing the construction of refrigeration appliances of different types, makes it possible to use uniform parts for various types of appliances and thus to rationalize their production.
  • the object is achieved by having in a refrigerator with at least one storage compartment and a heat-insulating wall surrounding the storage compartment, which has an insulation material layer between an inner skin facing the storage compartment and an outer skin, wherein the outer skin comprises at least a bottom plate and a vertical wall plate and under the outer skin an evaporation container is arranged, in the bottom plate two opening into the evaporation container passage openings are formed, one of which, referred to as the inner passage opening, on the Dämmmaterial Mrs facing side of the vertical wall plate and the other, referred to as the outer passage opening, on the of the Dämmmaterial für opposite side of the vertical wall plate is located.
  • Such a bottom plate can be used uniformly both in a simple refrigerator with cold wall evaporator, in a no-frost refrigerator and in a combination refrigerator with any type of evaporator, since the inner opening surrounding both with a puncture of the storage compartment Inner skin can be connected as well as with a stemming from a no-frost evaporator hose, whereas a guided on the outside of the refrigeration device housing line can be connected from the usual in particular in combination refrigerators type to the outer passage opening.
  • connection piece is preferably provided on the underside of the base plate formed, which surrounds both openings.
  • the lower edges of the nozzle thus represent the lowest points on the underside of the bottom plate, which can reach a passing through one of the passages condensate drops.
  • a common nozzle surrounds both openings.
  • the nozzle preferably opens into an underlying collecting funnel whose upper edge is higher than a lower end of the nozzle.
  • a groove running onto the outer passage opening is preferably formed, so that a drain line for condensation water can be placed therein without overhanging the outside of the side wall plate.
  • a condensate drain line which runs over the outer passage opening, preferably results from the upper storage compartment of a combination refrigerator having at least two storage compartments arranged one above the other.
  • a lower edge of the vertical wall plate receiving male contour may be formed, which extends in an arc around the outer passage opening.
  • An outer edge of the outer passage opening may then be substantially flush with the outer side of the side wall plate, so that the outer side of the side wall plate with a minimum distance from an adjacent wall, be it the wall of a room in which the refrigerator is installed, or the wall of a Furniture in which it is placed can be arranged. This ensures good space utilization.
  • the outer passage opening is preferably slit-shaped.
  • a condensed water outlet passage of the inner skin of a storage compartment may be disposed immediately above the inner through hole of the floor panel.
  • a sealing body is preferably clamped between the condensation water outlet passage and the inner passage opening for sealing against the insulating material.
  • a drain line of a no-frost evaporator can be led from an evaporator chamber through the insulating material to the inner through hole.
  • the drain line is preferably tightly anchored to the inner passage opening in the insulating material.
  • a condenser may be at least partially immersed in the evaporation tank.
  • the refrigeration device according to the invention has a base unit, in which the evaporation container is housed.
  • a base unit can be constructed largely independent of the structure of the overlying refrigerator housing and can in identical form or with a small number of different parts in a variety of different types of refrigerators with one or more storage compartments, with Coldwall evaporator or with no-frost evaporator, Find use.
