Definitions

  • the invention relates to a refrigerator, in particular a freezer, which is open towards the front and has a cooling air curtain flowing from top to bottom along the open front.
  • Conventional (deep) refrigerated cabinets have insulation in the floor area in order to prevent undesirable penetration of warm ambient air into the (deep) refrigerated cabinet.
  • the base assembly of a (deep) refrigerated cabinet is insulated in a vapor-diffusion-tight manner.
  • the thickness of the insulation layer is designed at least for the outside dew point.
  • the aim and object of the present invention is to avoid the disadvantages of the prior art.
  • a major advantage of the (deep) refrigerated cabinet according to the invention can be seen in the fact that shelves, furniture fronts, etc. no longer have to be designed in the floor area of the (deep) refrigerated cabinet, which results in considerable cost savings. Furthermore, the components of the floor assembly could be designed to be service-friendly removable or removable will. Another advantage is the better cleaning ability of these parts of the (deep) refrigerated cabinet.
  • the figure shows a side view of the lower area of a (deep) refrigerator 1 in cross section.
  • the cooling air curtain 2 falls from top to bottom along the front, which is open towards the front. From this, the main flow passes through the return air grille 3 into the return air duct 4, which is arranged below the goods floor 5.
  • the secondary flow passes through the return air grille 3 into the first auxiliary duct 7. While the main flow of the cooling air curtain 2 flows through the return air duct 4 to the fan 6, the secondary flow of the cooling air curtain 2 flows after passing through the first auxiliary duct 7 below the return air duct floor or below the (low ) refrigerator base 8 and then through a second auxiliary duct 9 also to the fan 6.
  • the (deep) refrigerator 1 rests on several supports 10a and 10b. Thus, part of the cooling air curtain bypass flowing underneath the (deep) cooling cabinet floor 8 will escape from the floor assembly of the (deep) cooling cabinet 1 (represented by the arrows on the supports 10a and 10b).
