Definitions

  • the invention relates to a combined evaporator for the star and the cooling compartment of a household refrigerator, which extends over five sides of the star compartment.
  • Combined evaporators for star compartments which form the storage compartments for frozen goods, and the cooling compartments of refrigeration devices are basically designed so that they are each traversed by a refrigerant channel which has meandering sections, the areas of the evaporator sections and the length of the sections running therein Coolant channels must be matched to one another in such a way that, based on the relative duty cycle of the compressor, the required cooling capacity is supplied to the star and cooling compartments in such a way that neither the star compartments become too warm nor the cooling compartments too cold.
  • the sections of the evaporators assigned to the star and cooling compartments and the sections of the refrigerant channels running in these must be dimensioned and matched to one another in such a way that the compartments are supplied with the correct cooling capacity as accurately as possible.
  • An evaporator of the type specified at the outset known from DE-44 20 842 A1 is bent from a blank which consists of two adjacent rectangles, one of which is elongated and narrower and the other wider and shorter.
  • the narrower rectangle is bent around three bending lines, so that the evaporator sections result which extend over the sides, the bottom and the ceiling of the star compartment.
  • the wider rectangle contains the evaporator section, which extends over the rear of the star compartment, and the evaporator section for the cooling compartment, which is connected to this via a connecting web, the evaporator section of the rear being connected with a narrow side to one side of the evaporator section, which extends over one side of the star compartment. Because of its configuration, this known blank cannot be provided with a particularly favorable arrangement of the course of the refrigerant channel.
  • the object of the invention is therefore to provide a blank for an evaporator of the type specified in the introduction, in which the individual sections of the refrigerant channel can be arranged in a favorable form and preferably essentially symmetrically. Furthermore, a blank is to be created which can be produced in a material-saving manner and can be bent into the required shape in a simple and inexpensive manner.
  • this object is achieved by a combined evaporator for the star and the cooling compartment of a household refrigerator, which extends over five sides of the star compartment, which consists of a two-layer sheet metal plate provided with refrigerant channels in the shape of an H-shaped blank, on one side part in extension of the broadened central web, the circuit board part for the cooling compartment is connected, which is connected to the central web by a narrower connecting web that passes through the side part and is provided with free cuts, the side parts being approximately at right angles from the central web and from these projecting beyond the central web Legs are bent approximately at right angles towards each other.
  • the blank according to the invention, from which the evaporator is bent is characterized by a simple symmetrical shape in which the individual sections of the refrigerant channel are arranged with a profile that is favorable for the transmission of the cooling power.
  • the refrigerant channels experience a certain narrowing in the bending zones, they are expediently branched into two mutually parallel channel sections in the bending zones.
  • the circuit board shown in FIG. 1 consists of a double-layer sheet metal plate, preferably of aluminum or an aluminum alloy.
  • the sheet metal plates are connected to one another and the coolant channel is formed between the sheet metal plates by arching at least one sheet metal plate.
  • Evaporator boards of this type are conventional and are therefore not described in more detail in terms of their basic structure.
  • the circuit board 1 consists of a blank, the main part of which forms the evaporator section for the star compartment and is H-shaped.
  • This H-shaped part consists of a wide central web 2, which is bordered by side parts 3, 4, the end regions of which form legs 5, 6, 7, 8 projecting beyond the central web.
  • a rectangular evaporator section 10 is connected to the central web 2 by a connecting web 9, which is arranged in the extension of the central web 2 and has approximately the same width as this.
  • This evaporator section 10 forms the evaporator part for the refrigerator compartment.
  • the connecting web 9 passes through the side part 4 in the middle and is separated from it by free cuts.
  • the connecting web 9 can also be arranged off-center.
  • the evaporator section 10 is separated from the side part 7 on the sides by a cut-out which has the width a.
  • the evaporator sections shown in FIG. 2 for the star compartment and the cooling compartment are bent from the blank according to FIG. 1.
  • the bending lines are indicated in FIG. 1 by dash-dotted lines 12.
  • the sections of the coolant channel 13 which pass through these are divided by branches into two channel sections 14 which are parallel to one another.
  • FIG. 2 shows a perspective view of the circuit board according to FIG. 1 bent into its final shape.
  • the basic section of the evaporator section for the star compartment consists of a box-shaped housing which is open on the side of the door of the star compartment.
  • the back of the evaporator part for the star compartment consists of the central web 2 of the board.
  • the bottom and top sides are formed by the middle parts of the side parts 3, 4. Of these, the legs 5, 6 and 7, 8 are bent towards each other so that they extend over the sides of the star compartment.
  • the evaporator section 10 for the cooling compartment which is connected to the web 9, is located below the evaporator part for the star compartment in the manner shown, the connecting web 9 passing through the insulating wall between the star compartment and the cooling compartment.
  • the evaporator sections can be exposed in the star and cooling compartment or can also be foamed behind the walls of the star and cooling compartment.
