The innovation concerns a two-temperature MUhlsohrank with one Korma-Udiblraum, in which a deep-freeze surrounded by ureolated wounds arranged with an evaporator and a defrostable room evaporator attached at a distance from a vertical wall of the freezer compartment Is «which with the evaporator inside the freezer compartment through KHltefflittel lines connected «which emerge at the top of the freezer compartment and in the air flow circulating over the freezer compartment in the NoiroalkUhlraum lie.

The innovation is based on the task of operating the refrigerator to reduce icing of the refrigerant lines emerging at the top of the freezer compartment and to prevent air circulation is worsened or even prevented by excessive ice accumulation in a normal cold room. This task becomes after the innovation solved that the refrigerant lines emerging from the TiefkUhlfaoh are shielded with a guide device, which rejects the air flowing around the freezer compartment from the KaTteraittelleitungen.

Through this guide device, the flowing over the deep-freeze, relatively warm and humid air from direct contact with the cold Shielded refrigerant lines. This prevents the humidity from building up between the individual defrosting cycles of the refrigerator heavily precipitated as frost or ice on these refrigerant lines and so no longer completely melted when defrosted can be.

An advantageous development of the subject of the innovation results With a defrost heater arranged on the room evaporator, it consists of a heating wire embedded in a film in that the guide device is formed from a flap of the film placed over the refrigerant lines.

In the drawing are two exemplary embodiments of the innovation according to the invention Guide device for a two-temperature cooling tank with a normal cooling room shown, in which a TiefkUhlfaoh surrounded by heat-insulated walls with an evaporator and one at a distance from the rear wall the freezer compartment attached defrostable room evaporator is arranged.

Pig. 4 is a view of a second embodiment.

In a two-temperature refrigerator 1 designed as a table-top refrigerator, dessei with a door indicated by dash-dotted lines 2 lockable refrigerated goods container 3 of the. Forms normal cold room, a deep-freeze compartment 4 is arranged. This freezer compartment 4 is surrounded by thermally insulated walls and has another thermally insulated door 5, with which it is on the door side of the Refrigerator is lockable. The TiefkUhlfaoh 4 is box-shaped and used as an independent component in the upper portion of the refrigerated goods container 3 that between its door 5, and its ceiling and its rear wall on the one hand and the door 2, as well as the ceiling and the rear wall of the refrigerated goods container on the other hand, a channel 6 is formed, duroh the im Normal cold room enclosed air can be circulated. Inside the freezer compartment an evaporator 7 is arranged. On the outside of the back of the freezer compartment 4, a room evaporator 8 is attached at a distance from its rear wall, which hangs down vertically in the channel 6. This room evaporator 8 is connected to the evaporator 7 in the TiefkUhlfaoh via refrigerant lines 9, which emerge from the heat-insulated roof wall at the top of the deep-freeze area.

The room evaporator 8 is equipped with a defrost heater 10, which is arranged on its surface facing the rear wall of the freezer compartment * The defrost heater 10 consists of a heating wire 11 which is inserted into a Foil is embedded, which is firmly pressed by a plate 12 to the Oberfläohe the Raumverdarapfers. As in particular from FIG. 2 is apparent, the strip-shaped film extends almost over the entire width of the room evaporator. The film has a protruding side Tab 13 * which is also provided with a heating wire.

In the embodiment according to FIGS. 1 to 3, the film has between its strip-shaped section and the tab 13 an incision 14 for the passage of the refrigerant lines 9. This version of the defrost heater allows the flap 13 to be placed on the outside of the room evaporator Cover and from the outside against the refrigerant lines to let concern. The upper edge of the flap 13 is pushed against the upper edge of the rear wall of the freezer compartment and is covered by an adhesive strip that is stuck to the freezer compartment. The tab 13 forms a guide device, with the help of which the freezer compartment in the direction of in Fig. 1 drawn arrows around the air flowing from the freezer compartment escaping refrigerant lines 9 is shielded.

In the second embodiment shown in Fig. 4, the defrost heater 10 'no incision, so that the flap 13' only from the inside can be applied against the refrigerant lines 9 ago. In this case, the guide device is made of a plastic, bent Formed strip 16, which is placed from the outside over the refrigerant lines and attached to the top of the freezer compartment.
