As for a refrigerator with a refrigerating chamber above the freezing chamber, a user needs to bend down to open the door body of the freezing chamber upon taking out of ice. To enable the user to conveniently take ice, an independent ice-making chamber is disposed in the refrigerating chamber or a door body of the refrigerating chamber of some conventional refrigerators, the ice maker is disposed in the ice-making chamber, and a dispenser associated with the ice maker is disposed on an outer side of the door body.

The door body needs to be often opened and closed so that the cold air is apt to leak, thereby increasing the energy consumption of the refrigerator. Furthermore, introduction of cold air from the cabinet is apt to cause mixing of smells. Therefore, there arise refrigerators in which ice is made by using a refrigerant pipe in direct contact with the ice maker. In such a type of refrigerators, the refrigerant pipe needs to pre-mounted on the door body and then foaming is performed for the door body. If there is any error in the mounting of the refrigerant pipe, the refrigerant pipe after subsequent foaming deviates or cannot be mounted in alignment with the ice maker, thereby causing the scrapping of the whole door body.

[0046] With reference to FIG. 9, the door body 10 is further provided with a heat exchanger 50 and a liquid storage bag 60 which are connected to the refrigerating system, a pipeline of the refrigerating system passes through a hinge of the door body and is connected to the heat exchanger 50; the refrigerant pipe 30 is connected to the heat exchanger 50 and the liquid storage bag 60 respectively; the refrigerant from the refrigerating system passes through the heat exchanger 50, the liquid storage bag 60 and the refrigerant pipe 30 in turn, returns through the refrigerant pipe 30 to the heat exchanger 50, and then returns from the heat exchanger 50 to the refrigerating system, and both the heat exchanger 50 and the liquid storage bag 60 are provided between the door liner 12 and the door shell 11. A part of the refrigerant pipe 30 is located at the bottom of the ice-making assembly, and the evaporation area is small, so that a large amount of cold of the refrigerant does not escape. If this cold does not escape, it will enter the pipeline of the refrigerating system and exit the door body through the hinge. When the cold passes through the hinge, it will condense or even form frost. With the heat exchanger 50 and the liquid storage bag 60 being provided on the door body 10, the cold of the refrigerant may be dissipated, thereby solving the problem of condensation when the pipeline of the refrigerating system passes through the hinge. In addition, the addition of the liquid storage bag 60 to the door body 10 allows the refrigerant to be stored and allows the refrigerant to dissipate more cold.

By arranging the cooling pipe 51 and the air return pipe 52 on the door body in a circuitous manner, the length of the air return pipe 52 is increased, and the cool can be sufficiently dissipated. A diameter of the cooling pipe 51 is larger than the diameter of the air return pipe 52, so that the heat exchange efficiency of the heat exchanger can be improved.
[0048] Furthermore, the refrigerant pipe 30 further includes a connection portion 35 connected between the liquid storage bag 60 and the direct cooling section 32.

In addition, the liquid storage bag 60 may be provided in the form of a cylinder that is disposed with an axial direction parallel to the vertical extension section of the heat exchanger 50 to facilitate the assembling within the door body. Furthermore, in order to prevent noise occurring in the operation of the liquid storage bag 60, a soundproof material such as silica gel or foam may wrap the outside of the liquid storage bag 60, thereby reducing noise.
[0050] The pipeline of the refrigerating system includes an inlet pipe 915 from the cabinet to the door body and a return pipe 916 from the door body to the cabinet, wherein both the inlet pipe 915 and the return pipe 916 pass through a hinge between the door body and the cabinet, and at least a part of the inlet pipe 915 and the return pipe 916 passing through the hinge is wrapped by closed-pore foam, so that the inlet pipe 915 and the return pipe 916 do not come into contact with air, thereby solving the problem of condensation on the part of the pipeline passing through the hinge. Furthermore, a protective pipe 16 extending downward from the hinge is provided in the door body, and the inlet pipe 915 and the return pipe 916 may be wrapped in the protective pipe 16. In addition, a water pipe for supplying water to the ice-making assembly may also be wrapped in the protective pipe 16 to facilitate the assembling of the door body.
[0051] In addition, the heat exchanger 50 and the liquid storage bag 60 are preferably provided on a thermal insulation layer between the door shell 11 and the door liner 12.
