Here, the refrigerator further includes a wiring box 60 located above the slide rail assembly 30 and fixed to the moving rail 32 and/or the support frame 23 . A first insertion port 61 is formed at the rear end of the wiring box 60 , and the movable end 51 is inserted into the first insertion port 61 . The cable 40 extends forward from the movable end 51 of the drag chain 50 and passes through the wiring box 60 and is then connected to the drawer door 20 , that is, the cable 40 is connected to the drawer door The part of 20 is accommodated in the wiring box 60 .

The support frame 23 is further formed with a receiving groove 231 extending back and forth and used for receiving the wiring box 60. The receiving groove 231 is open to the side facing the interior of the compartment 10; the wiring box 60 faces One side inside the receiving groove 231 is also open. That is to say, the wiring box 60 and the accommodating slot 231 together form a space for accommodating part of the cables 40 . The moving rail 32 protrudes upward to form a holding portion 321 to make the assembly of the moving rail 32 and the support frame 23 more stable. The wiring box 60 is formed to cooperate with the holding portion 321 the limiter 62. The limiting portion 62 is concave and bent upwards, which is also beneficial to locally restrain the cable 40 and prevent the cable 40 from jumping behind the wiring box 60 . Obviously, the wiring box 60 and the moving rail 32 can also be fixed with the support frame 23 through other mechanical structures.

The drag chain 50 has a first connecting part close to the movable end 51 and a second connecting part close to the fixed end 52, the first connecting part and/or the second connecting part from front to back along a predetermined elevation angle α Extends upwards. Since the drag chain 50 will be partially sagging and deformed under the action of gravity, the predetermined elevation angle α can prevent the drag chain 50 from sagging locally and avoid the drag chain 50 from being touched and worn. Wherein, the predetermined elevation angle α is set to be 2°˜10°.

In this embodiment, the refrigerator further includes an installation box 70 fixed on the side wall 11 , and the installation box 70 is formed with a second socket 71 matched with the fixed end 52 . 52 is inserted into the second insertion port 71 . The installation box 70 also has a fixing hole 72 which is offset from the second socket 71 in the height direction, and the fixing hole 72 is used to realize the fixed installation of the installation box 70 . The installation box 70 is located above the support frame 23 , in other words, the drag chain 50 extends backward from its movable end 51 and extends forward after being bent upwards and turned over. The second connecting portion is located above the first connecting portion. In order to prevent the drag chain 50 from sagging and rubbing against the support frame 23, the slide rail assembly 30, etc., the first connecting portion is arranged along the predetermined elevation angle. Alpha extension settings. Specifically, the first socket 61 has a top plate 611 and a bottom plate 612 which are vertically opposite and extend from front to back along a predetermined elevation angle α.

A blocking mechanism is also provided on the side wall 11 of the compartment 10 , the blocking mechanism is located behind the installation box 70 , and the blocking mechanism is set slightly higher than the second socket 71 in the height direction. Here, the blocking mechanism is provided as a blocking rib 13 protruding from the side wall 11 toward the interior of the compartment 10, the blocking rib 13 can avoid interference with the towline 50 in normal operation, and when the When the towline 50 freezes, along with the movement of the drawer-type door 20, the blocking ribs 13 can limit the upwardly protruding deformation of the towline 50, so as to avoid damage to the towline 50 and facilitate the normal operation of the towline 50. state. Of course, the blocking mechanism can also be set as other blocking members fixed on the side wall 11 .

The drag chain 50 is composed of several chain links 53 connected in sequence, and the adjacent chain links 53 can rotate along a predetermined rotation axis. Each of the chain links 53 has two clamp plates 531 disposed opposite to each other, and two baffle plates 532 connecting the two clamp plates 531 . The clamp plates 531 and the baffle plates 532 together form a cavity for accommodating the cable 40 . The two baffles 532 of the chain link 53 corresponding to the movable end 51 are in cooperative contact with the aforementioned top plate 611 and bottom plate 612 , so that the first connecting portion extends at a predetermined elevation angle α. The two ends of the splint 531 are respectively provided with a connecting hole 533 and a connecting column 534. The connecting hole 533 and the connecting column 534 are respectively connected with the connecting column 534 and the connecting hole in the adjacent chain link 53 on the corresponding side. 533 are butted together, so that the adjacent chain links 53 can be mutually rotated along the axial direction of the connecting hole 533 and the connecting column 534 . That is to say, the axes of the connection holes 533 and the connection posts 534 are the predetermined rotation axes of the adjacent chain links 53 . Generally, the connecting hole 533 and the connecting column 534 are respectively set as a circular hole and a cylinder, so that the adjacent chain links 53 can keep free movement.

The first plug-in port 61 and the second plug-in port 71 are usually set in a rectangular shape and are adapted to the size of the chain link 53 , and the first plug-in port 61 and the second plug-in port 71 are respectively formed with the same configuration as the above. The connection hole 533 or the connection post 534 is matched with the plug-in structure. Here, the first insertion port 61 is provided with an insertion hole 613 matched with the connection post 534 , and a reinforcing portion 614 with a thicker thickness is formed at the corresponding position of the insertion hole 613 to improve the drag Assembly strength of the chain 50 . The second insertion port 71 is provided with an insertion post 711 matched with the connection hole 533 , and a guide surface 712 is formed on the rear side of the insertion post 711 to facilitate the assembly of the drag chain 50 . Further, a stopper block 713 is formed in the second socket 71 , and the stopper block 713 cooperates with the baffle plate 532 of the chain link 53 to avoid connecting holes in the corresponding chain link 53 . When the 533 is plugged with the plug-in post 711, the misalignment occurs, which reduces assembly errors and component damage. Of course, the first socket 61 can also be provided with a corresponding stop structure.

In general, the drag chain 50 is bent in the height direction as described above, and the axes of the connecting holes 533 and the connecting columns 534 , that is, the predetermined rotation axis between the adjacent chain links 53 extend along the left and right horizontal directions. . However, in actual assembly, due to the different fixing positions of the wiring box 60 and the installation box 70 , the position of the second socket 71 is often closer to the side wall 11 of the compartment 10 , thereby causing the drag chain 50 Torsional stress occurs between adjacent chain links 53 in the middle, which increases wear and noise. In order to overcome the above problem, we deflect the predetermined rotation axis between the adjacent chain links 53 along the height direction, and the deflection angle β of the predetermined rotation axis relative to the left-right horizontal direction is preferably set to 5°˜10°. The drag chain 50 extends backward from the first socket 61 , then bends upward and extends toward the side wall 11 , and then connects to the second socket 71 . In other words, the bending part of the drag chain 50 is deflected toward the side wall 11 by the deflection of the rotating shaft between the adjacent chain links 53 (as shown in FIG. 5 and FIG. 9 ). The above-mentioned structural design is more compact and reasonable, which facilitates the structural optimization design of the installation box 70 .

In order to realize the deflection of the predetermined rotating shaft, we can deflect the first socket 61 and the second socket 71, so that the axial directions of the sockets 613 and the sockets 711 are relative to the left and right horizontal directions. The deflection angle of the two is the same, so as to better avoid the corresponding twisting stress on the drag chain 50 . That is to say, the axial directions of the insertion holes 613 and the insertion posts 711 are both set at a deflection angle β relative to the left and right horizontal directions.

Here, the mounting box 70 is directly fixed on the side wall 11 , the mounting box 70 is correspondingly formed with a mounting surface for abutting on the side wall 11 , and the side edge of the second socket 71 is The aforementioned deflection angle β is formed with respect to the mounting surface. It should be noted that the wiring box 60 is fixed on the support frame 23 , and the deflection of the first socket 61 can pass through at least one of the installation box 60 and the receiving slot 231 of the support frame 23 . To achieve the structural design, it only needs to ensure that after the assembly is completed, the aforementioned deflection angle β is formed in the axial direction of the first insertion hole 613 in the first insertion port 61 .

To sum up, the present invention achieves stable electrical connection between the drawer-type door 20 and the compartment 10 through the drag chain 50 . In addition, the first connecting part and/or the second connecting part close to the two ends of the drag chain 50 are inclined at a predetermined elevation angle, which effectively prevents the drag chain 50 from partially hanging down and interferes with the slide rail assembly 30, thereby reducing wear. In addition, the installation structure of the drag chain 50 in the refrigerator of the present invention is more compact and reasonable, beautiful and reliable.
