Definitions

• the present invention relates to a household refrigerator, in particular a combination refrigerator with a cooling tank and a freezer compartment forming inner container, a box evaporator, which surrounds the freezer compartment trough on four sides, and a plate evaporator, one at a back of the
• Refrigerator tray arranged plate comprises.
• Such a refrigeration device is known from DE202005000909U1.
• a large expansion of the evaporator is particularly interesting in a freezer, because the larger the evaporator surface, the smaller the can
• the object of the present invention is therefore to provide a combination refrigeration device that is rational to manufacture and thereby allows cooling of the freezer compartment tub on more than four sides.
• the object is achieved by a second plate of the plate evaporator, of which a plate already cools the back of the refrigerating compartment, is also arranged on a rear side of the freezer compartment.
• the plate evaporator can be mounted in a single operation on both trays at the same time, so that the production cost compared to the conventional refrigeration device is only slightly increased.
• the plate evaporator is designed as a tube-on-sheet evaporator. This simplifies the production of a refrigerant-conducting connection between the two plates of the plate evaporator.
• a refrigerant pipe of the plate evaporator integrally extends over the first and second plates to avoid soldering between the plates and associated possible leakage and the labor of soldering.
• Box evaporator is preferably formed on a second plate. That's how it works
• the large extent of the evaporator surface on the freezer compartment tub allows in particular a structure of the refrigerant circuit, in which the box evaporator is connected upstream of the plate evaporator.
• the refrigerant tube is expediently less densely laid on the first plate of the plate evaporator than on the second.
• FIG. 1 shows an exploded view of an inner container and a
• Fig. 1 shows an integrally deep-drawn inner container 1 for a combination refrigerator in a perspective view.
• the inner container 1 comprises a freezer compartment trough 2 and, separated therefrom by a gap 3, a refrigerating compartment trough 4 which is not completely shown in the figure.
• Both troughs 2, 4 are substantially cuboid with an open front.
• Side walls 5, 6 ceiling and bottom of the freezer compartment 2 are large plates of metal plates 7, in particular made of aluminum, covered.
• One Refrigerant tube 8 extends helically around the side walls 5, ceiling 6 and the bottom of the freezer compartment 2 and is heat-conducting attached to the metal plates 7 to form a box evaporator 18.
• a plate evaporator 9 is spaced in the figure from backs 10, 11 of FIG.
• the plate evaporator 9 formed in tube-on-sheet technology comprises two metal plates 12, 13 which are provided for attachment to the rear sides 10, 11, and a refrigerant tube 14 which extends integrally over both plates 12, 13 and to these soldered or glued thermally conductive.
• the metal plate 12 is sized to fully fill the back 10 to its rounded edges; the metal plate 13 may be smaller than the back 1 1 of the cooling compartment tray. 4
• An inlet port 15 of the refrigerant pipe 14 is located between the two metal plates 12, 13; proceeding from there, the refrigerant tube 14 initially extends in loose meanders on the metal plate 13 downwards, then rises again at the edge of the plate 13, then to bridge the gap between the plates 12, 13 and on the metal plate 12 in comparison to the plate 13 closer
• a cranked portion 16 between the plates 12, 13 compensates for an offset in the depth direction between the backs 10, 1 1 of the troughs 2, 4.
• An outlet port 17 is above a corner of
• Inner container 1 to be soldered at one end of the refrigerant pipe 8 ..
