The water tank 30 can be filled by manual addition to meet the water demand of the ice maker 40. And, water in the water box 30 is pre-cooled by the first compartment 23 and then is filled into the ice maker 40 to make ice, so that the ice making efficiency of the ice maker 40 is improved.

Specifically, the first water pipe 29a passes through the insulating layer 27 above the ice maker 40. In this embodiment, the fixed end of the first water pipe 29a is connected to the bottom of the water box 30, and the free end of the first water pipe 29a is located in the second compartment 25a and above the ice maker 40. Moreover, first water pipe 29a passes through first inner bag 23 and second inner bag 25 simultaneously to arrange in the heat preservation 27 between first inner bag 23 and second inner bag 25, thereby shortened the length of first water pipe 29a, thereby difficult quilt 27 the foaming process of heat preservation leads to the dislocation.

In this embodiment, since the air inlets and the air outlets of the first compartment 23a and the second compartment 25a are both located at the side of the door 20 close to the hinge of the door 20 and the box 10, and the water supply valve 29c is disposed at the side of the first compartment 23a away from the hinge of the door 20 and the box 10, the air inlet of the first compartment 23a can be prevented from directly blowing the water supply valve 29c. Causing the water supply valve 29c to be excessively cooled to fail to operate normally. For this reason, the fourth tube 29b1 needs to surround the edge of the first inner container 23 and then be abutted against the water supply valve 29c in the first compartment 23 a. Similarly, because the air duct member for supplying air to the first compartment 23a and the second compartment 25a is disposed on one side of the door 20 close to the hinge, the side tube 29b11 is disposed on one side of the first inner container 23 away from the hinge of the door 20 and the box 10, so as to provide an installation space for the air duct member and avoid radiation of cold in the air duct member.
