Definitions

  • the invention relates to a freezer with an evaporator part arranged in an upper cabinet section, preferably a lamella evaporator, with freezer compartments provided underneath the evaporator part or with drawers held in guides of the side cabinet walls and with cooling air channels running approximately parallel to the rear wall of the cabinet and to the cabinet door, which pass into cooling air outlet and cooling air inlet gaps of the evaporator part open and the passage gaps provided for convective air circulation through bilateral freezer compartments or freezer drawers, forming branch channels and running approximately horizontally, are connected to one another.
  • Freezers of this type are known as so-called no-frost freezers and differ from conventional freezers in which evaporator plates are arranged in the freezer compartment in that convective air circulation is used.
  • a blower is arranged in the evaporator part, which maintains the circulating air flow.
  • ice can form on the evaporator plates, which necessitates the freezer at regular intervals defrost.
  • an inclined insulation and baffle plate is arranged below the finned evaporator, through which condensation water can flow, which is led via a line to an evaporation tray connected to the compressor, so that defrosting is possible without to warm the freezer compartment above 0 ° C.
  • No-frost freezers work uneconomically if not all of the compartments or drawers are filled with frozen goods, because then the full available cooling capacity will not be used.
  • the object of the invention is therefore to provide a freezer of the type mentioned, which works economically even when not fully loaded.
  • this object is achieved in a freezer of the generic type in that an insulating separating plate can be inserted below the first compartment or the first drawer in the area of the subsequent compartment or the underlying drawer, the edges of which lie sealingly against the cabinet walls and the door .
  • the freezer according to the invention makes it possible to initially only occupy the upper compartments or drawers in the case of a partial load and to remove the drawer following the occupied drawers and instead to use the insulating partition plate.
  • This partition plate separates the part of the freezer which is filled with refrigerated goods from the unloaded part, so that only the part of the freezer which holds the refrigerated goods is cooled by the cooled circulating air.
  • the partition plate itself does not hinder the air circulation, it only shortens the path of the air circulation.
  • the cooling capacity adapts itself to the required reduced capacity, so that the freezer according to the invention works more economically.
  • the situation must be reversed accordingly, i.e. first the lower compartments or drawers must be loaded and the partition plate inserted above the loaded compartment or the loaded drawer.
  • the partition plate itself expediently has a conventional heat-insulating layer or a heat-insulating core filling.
  • a heat-insulating layer or a heat-insulating core filling.
  • it is provided along its edges with sealing strips made of elastomeric material, which rest against the walls and the door of the freezer and which result in a hermetically sealed closure.
  • the cooling air duct running parallel to the rear wall of the cabinet is separated from the cooling space by a plate running parallel to the rear wall, which is provided with outlet gaps for the cooling air.
  • the separating plate passes through a plate running parallel to the rear wall and delimiting the cooling channel in cooling air outlet slots provided between the compartments or drawers. It is essential that the main cooling air flow is reduced, which runs downwards from the finned evaporator parallel to the rear wall
  • the partition plate is provided in the front region of its lateral edges with bars or locking elements which snap into recesses in the side walls.
  • the latches lock the partition plate in place and indicate that it is correct, that is used sealingly. Even during operation, the bolts or locking elements ensure that the separating plate does not slip and the effect thereof can be impaired.
  • Spring-loaded latches or locking elements are expediently provided, which snap into the recesses when the partition plate is inserted and are provided with actuating devices for releasing them. This configuration simplifies handling because the partition plate only has to be inserted at the correct height and is automatically locked in its correct position.
  • guides for the partition plate are provided in the side walls below the first compartment or the first drawer in the area of the following compartments of the drawers. If the refrigerator is equipped with drawers, only the first unoccupied drawer needs to be removed and the separating plate inserted into the gap that results.
  • FIG. 1 A so-called no-frost freezer with convective air circulation is shown in longitudinal section in FIG.
  • the freezer consists of a cabinet part with side walls, rear wall and floor and top wall, which are foamed with heat-insulating plastic foam.
  • the front of the freezer 1 is closed by a freezer door 2.
  • the freezer is provided with an upper section 3, which is sealed off from the freezer room below by an oblique insulating guide plate 7.
  • a slat evaporator 5 and a cooling fan 6 are arranged obliquely in the upper section 3.
  • the section receiving the finned evaporator 5 and the cooling fan 6 is connected via a cooling air outlet gap 11 to the cooling air duct 12 running parallel to the rear wall and through an inlet gap 13 to the cooling air duct 14 running parallel to the cabinet door.
  • pull-out drawers 15 are arranged in the freezer compartment of the freezer in corresponding guides or on a corresponding holding plate, which serve to hold the refrigerated goods. Between the uppermost drawer 15 and the insulated guide plate 7 there is also a freezer tray 4 in the form of a low drawer, which is also held in guides in a pull-out manner.
  • the freezer is of a known type, so that a further description can be dispensed with.
  • Refrigerators can be seen in FIG. 2, in which the partition plate 16 is inserted instead of the fourth or fifth drawer. This shortens the circulating air flow of the cooling air by 50 or 30 percent, which results in a corresponding energy saving.
  • the areas 18, 19 of the separating plate in which the latching devices are arranged are identified in FIG.
