Definitions
- the invention relates to a combined evaporator for the Freezer and the refrigerator compartment of a household refrigerator, which itself extends over five sides of the freezer compartment.
- Combined evaporators for freezer compartments which are the storage compartments for Form frozen goods, and the refrigeration compartments of refrigeration units are basic designed so that they each have a refrigerant channel are traversed, which has meandering sections, the areas of the evaporator sections and the length of the in this extending sections of the coolant channels one on the other must be coordinated based on the relative duty cycle the freezer and freezer compartments the required cooling capacity is supplied in such a way that neither the freezer compartments become too warm or the refrigerator compartments become too cold. For this reason, the freezer and refrigerator compartments must be assigned Sections of the evaporators and those running in them Sections of the refrigerant channels are dimensioned and matched to one another be that the subjects have the correct cooling capacity as precisely as possible is fed.
- An evaporator known from DE-44 20 842 A1 of the type mentioned Art is bent from a blank, the one from two side by side There are rectangles, one of which is elongated and narrower and the other wider and shorter is.
- the narrower rectangle is bent around three bend lines, so that there are the evaporator sections, which are about extend the sides, bottom and top of the freezer compartment.
- the wider rectangle contains the evaporator section, which is extends over the back of the freezer compartment, and the one with this evaporator section connected via a connecting web for the refrigerator compartment, the evaporator section with the back a narrow side connected to one side of the evaporator section that extends over one side of the freezer compartment. Because of its configuration, this known blank can be made not with a particularly favorable arrangement of the course of the refrigerant channel.
- the object of the invention is therefore to provide a blank for a To create evaporators of the type specified in the the individual sections of the refrigerant channel in a favorable form and preferably arranged essentially symmetrically. Furthermore, a cut is to be created that saves material produce and in a simple and inexpensive way in the can bend required shape.
- this object is achieved by a combined evaporator for the freezer and refrigerator compartments of a household refrigerator, which extends over five sides of the freezer compartment, that of a two-layer with refrigerant channels Sheet metal in the shape of an H-shaped blank one side part in the extension of the broadened central web the circuit board part for the refrigerator compartment is connected, the through a cut through the side part and with free cuts provided narrower connecting web connected to the central web is solved, with the side parts approximately at right angles from the central bridge and of these the towering over the central bridge Legs bent approximately at right angles towards each other are.
- the cutting of the board according to the invention, from which the Evaporator is curved is characterized by a simple symmetrical Form out in which the individual sections of the refrigerant channel with a favorable one for the transmission of the cooling capacity Are arranged.
- the board shown in Fig. 1 consists of a double-layered Sheet metal plate, preferably made of aluminum or an aluminum alloy.
- the sheet metal plates are connected to each other and between the sheet metal plates is arched by at least one sheet metal plate the coolant channel is formed.
- Such evaporator boards are of a common nature and are therefore their basic structure after not described in more detail.
- the board 1 consists of a blank, the evaporator section for the freezer compartment forming main part H-shaped is.
- This H-shaped part consists of a wide central web 2, which is bordered by side parts 3, 4, the end regions the legs 5, 6, 7, 8 projecting above the central web.
- the central web 2 is a rectangular through a connecting web 9
- Evaporator section 10 connected in extension of the central web 2 is arranged and has approximately the same width like this one.
- This evaporator section 10 forms the evaporator part for the refrigerator compartment.
- the connecting web 9 penetrates the side part 4 is in the middle and is cut by this Cut.
- the connecting web 9 can also be arranged off-center become.
- the evaporator section 10 is from the side part 7 the sides separated by a free cut that the width a having.
- FIG. 1 can be seen from the blank in FIG. 2 Evaporator sections for the freezer compartment and the refrigerator compartment bent.
- the bending lines are dash-dotted in Fig. 1 Lines 12 indicated. In the area of the bending lines are the through these sections of the coolant channel 13 Branches in two parallel channel sections 14 divided up.
- FIG. 2 is a perspective view of its final Form bent circuit board according to Fig. 1 can be seen.
- the evaporator section there is a basic one for the freezer compartment Shape from a box-shaped case that is on the side the freezer door is open.
- the back of the evaporator part for the freezer consists of the middle bar 2 of the board.
- the bottom and top sides are through the middle parts of the Side parts 3, 4 formed. Of these, the legs are 5, 6 and 7, 8 bent towards each other, so that this extends over the sides of the freezer compartment.
- the evaporator section connected to the web 9 10 for the refrigerator compartment is shown in the Way below the evaporator part for the freezer compartment, the connecting web 9 the insulating wall between the Freezer compartment and the refrigerator compartment interspersed.
- the evaporator sections can be exposed in the freezer and refrigerator compartment or behind the walls of the freezer and refrigerator compartment be foamed.
