Abstract

A cold appliance comprising a cooling module (102) and a cabinet (101) comprising a cold compartment (104). The cooling module comprises an air outlet (43) delivering cooled air to the cold compartment and an air inlet (44) receiving air from the cold compartment. The cooling module is arranged at the bottom of the cold appliance, and comprises a cold section (34), and a warm section (35), which is separated from the cold section by an insulating wall (105). An evaporator (33) is arranged in the cold section, and a compressor (36) and a condenser (32) is arranged in the warm section. The condenser comprises a condenser tube (32), which is arranged in windings on or integrated in a bottom plate (31) of the cooling module.

Claims

1. A cold appliance comprising a cooling module (102), and a cabinet (101), which comprises a cold compartment (104), wherein the cooling module comprises an air outlet (43) delivering cooled air to the cold compartment, and an air inlet (44) receiving air from the cold compartment, wherein the cooling module is arranged at the bottom of the cold appliance, and wherein the cooling module comprises a cold section (34), a warm section (35), which is separated from the cold section by an insulating wall (105), an evaporator (33) arranged in the cold section, and a compressor (36) and a condenser (32) arranged in the warm section, characterized in that the condenser comprises a condenser tube (32), which is arranged in windings on or integrated in a bottom plate (31) of the cooling module.

2. A cold appliance according to claim 1, wherein the cooling module (102) comprises a drain water tray (46), which is arranged adjacent to the condenser tube (32), for receiving defrost water from the evaporator (33).

3. A cold appliance according to claim 2, wherein the drain water tray (46) is constituted by a portion of the bottom plate (31).

4. A cold appliance according to claim 2, wherein the drain water tray (46) is constituted by a separate tray arranged on top of the condenser tube (32).

5. A cold appliance according to claim 2, wherein the condenser tube (32) is arranged inside the drain water tray (46).

6. A cold appliance according to claim 2, wherein the cooling module (102) further comprises a defrost water collecting device (48) arranged below the evaporator (33), and a draining pipe (49) extending from the defrost water collecting plate to the drain water tray (46), and guiding the defrost water to the drain water tray.

7. A cold appliance according to claim 6, wherein the defrost water collecting device (48) comprises a plate or a tray on or in which the evaporator (33) is arranged.

8. A cold appliance according to claim 1, wherein the cabinet (101) comprises two side wall panels (1) and a rear wall panel (4), and wherein at least one of the side wall panels, preferably the side wall panel which party encloses the cold section (34) of the cooling module (102), is attached to the bottom plate (31).

9. A cold appliance according to claim 8, wherein at least one of the side wall panels (1) or the rear wall panel (4) comprises a pre-foamed panel, preferably made in a continuous double belt foaming process.

10. A cold appliance according to claim 1, wherein the bottom plate (31) comprises a support means, such as feet and/or wheels, and preferably also levelling means.

11. A cold appliance according to claim 1 wherein a condensation preventing device (160) comprising a heat carrier tube (28, 160) is arranged in thermal contact with the condenser tube (32).

12. A cold appliance according to claim 1, wherein the bottom plate (31) comprises fastening means for securely fasten the compressor, and preferably also fastening means for securely fasten a fan and part of a door hinge.
