Referring to fig. 1, the refrigerator according to the present invention includes a compartment 10 opened forward and a drawer type door 20. The compartment 10 is provided with two side walls 11 which are oppositely arranged at the left and the right; the drawer-type door body 20 is movable in a front-rear direction to open or close the compartment 10.

The drawer-type door 20 is provided with an electrical component, which may be a touch display screen 21. A drawer box 22 for storing articles is further disposed at the rear side of the drawer door 20, the drawer box 22 moves along with the drawer door 20, and the drawer box 22 is preferably detachably disposed, that is, after the drawer door 20 is opened, the drawer box 22 can be taken out separately.

As shown in fig. 2 to 9, a fixing frame 12 is fixedly disposed on the side wall 11; the rear side of the drawer type door body 20 is fixedly provided with a support frame 23, and the refrigerator further comprises a slide rail assembly 30 arranged between the fixed frame 12 and the support frame 23. The part of the support frame 23 fixedly connected to the drawer door 20 and the part carrying the drawer box 22 may be integrally formed, or may be separately manufactured and then fixedly assembled. The slide rail assembly 30 includes a fixed rail 31 mounted on the fixed frame 12 and a movable rail 32 fixed to the support frame 23, and the slide rail assembly 30 is preferably disposed on one side of the support frame 23 facing the side wall 11. Here, the two sides of the drawer box 22 are further formed with a pressing portion 221 which presses against the support frame 23 downward and is bent downward to shield at least a portion of the support frame 23 and the movable rail 32, and the structure is more beautiful and tidy due to the shielding of the pressing portion 221.

The refrigerator further comprises a cable 40 electrically connecting the drawer-type door body 20 and the compartment 10, and a drag chain 50 accommodating at least a part of the cable 40, wherein both ends of the cable 40 are provided with corresponding electrical connectors (not shown); the tow chain 50 has a movable end 51 connected to the drawer door 20 and a fixed end 52 connected to the side wall 11. Here, the refrigerator further includes a wire box 60 located above the slide rail assembly 30 and fixed to the movable rail 32 and/or the support frame 23. The rear end of the wiring box 60 is formed with a first insertion opening 61, and the movable end 51 is inserted into the first insertion opening 61. The cable 40 extends forwards from the movable end 51 of the tow chain 50 through the walk-in box 60 and then is connected to the drawer-type door body 20, i.e. the part of the cable 40 connected to the drawer-type door body 20 is accommodated in the walk-in box 60.

The supporting frame 23 is further formed with an accommodating groove 231 extending in the front-back direction and used for accommodating the wiring box 60, and one side of the accommodating groove 231 facing the interior of the compartment 10 is open; the wiring box 60 is also opened toward the inside of the housing groove 231. That is, the routing box 60 and the receiving groove 231 together form a space for receiving a part of the cable 40. The movable rail 32 protrudes upwards to form a clamping part 321, so that the movable rail 32 and the support frame 23 are assembled more stably, and the wiring box 60 is formed with a limiting part 62 matched with the clamping part 321. The limiting portion 62 is bent to be concave upwards, so that local restraint on the cable 40 is facilitated, and the cable 40 is prevented from bouncing behind the wire routing box 60. Obviously, the wiring box 60 and the movable rail 32 may be fixed to the support frame 23 by other mechanical structures.

The drag chain 50 has a first connecting portion near the movable end 51 and a second connecting portion near the fixed end 52, and the first connecting portion and/or the second connecting portion extend obliquely upward from front to back along a predetermined elevation angle α. Since the drag chain 50 may be locally sagged and deformed under the action of gravity, the predetermined elevation angle α may prevent the drag chain 50 from locally sagging, and avoid the contact wear of the drag chain 50. Wherein the given elevation angle α is set to 2 ° to 10 °.

In this embodiment, the refrigerator further includes a mounting box 70 fixed on the side wall 11, the mounting box 70 is formed with a second insertion opening 71 matched with the fixing end 52, and the fixing end 52 is inserted into the second insertion opening 71. The mounting box 70 further has a fixing hole 72 deviating from the second socket 71 in the height direction, and the fixing hole 72 is used for realizing the fixed mounting of the mounting box 70. The mounting box 70 is located above the supporting frame 23, in other words, the drag chain 50 extends backward from the movable end 51 and extends forward after being bent and turned upward. The second connecting portion is located above the first connecting portion, and the first connecting portion is disposed to extend along the predetermined elevation angle α to avoid the drag chain 50 from sagging and rubbing against the supporting frame 23, the slide rail assembly 30, and the like. Specifically, the first socket 61 has a top plate 611 and a bottom plate 612 which are opposite to each other up and down and extend from front to back along a predetermined elevation angle α.

The side wall 11 of the compartment 10 is further provided with a blocking mechanism, the blocking mechanism is located behind the mounting box 70, and the blocking mechanism is arranged slightly higher than the second insertion port 71 along the height direction. Here, the blocking mechanism is provided as a blocking rib 13 protruding from the side wall 11 toward the inside of the compartment 10, the blocking rib 13 can avoid interfering with the normally operating tow chain 50, and when the tow chain 50 freezes, the blocking rib 13 can move along with the drawer type door 20, and can further limit the tow chain 50 from protruding upwards and deforming, so as to avoid damage to the tow chain 50 and facilitate the tow chain 50 to maintain a normal working state. Of course, the blocking mechanism may be provided as other blocking members fixed to the side wall 11.

The drag chain 50 is composed of a plurality of chain links 53 connected in sequence, and the adjacent chain links 53 can rotate along a predetermined rotation axis. Each link 53 has two oppositely disposed clamping plates 531 and two baffles 532 connecting the two clamping plates 531, and the clamping plates 531 and the baffles 532 together form a cavity for accommodating the cable 40. The two baffles 532 of the corresponding chain link 53 of the movable end 51 are in contact with the top plate 611 and the bottom plate 612, so that the first connecting portion extends at a predetermined elevation angle α. The two ends of the clamping plate 531 are respectively provided with a connecting hole 533 and a connecting column 534, the connecting holes 533 and the connecting column 534 are respectively butted with the connecting column 534 and the connecting hole 533 in the adjacent chain link 53 on the corresponding side, and the adjacent chain links 53 can rotate mutually along the axial direction of the connecting holes 533 and the connecting column 534. That is, the axes of the connecting holes 533 and the connecting posts 534 are the predetermined rotation axes of the adjacent links 53. Generally, the connecting holes 533 and the connecting posts 534 are configured as round holes and cylinders, respectively, so that the adjacent links 53 can keep free movement.

The first and

second insertion ports

61 and 71 are generally rectangular and adapted to the size of the chain link 53, and the first and

second insertion ports

61 and 71 are further respectively formed with insertion structures matching with the connection hole 533 or the connection post 534. Here, an insertion hole 613 matched with the connection column 534 is formed in the first insertion port 61, and a reinforcing portion 614 having a larger thickness is formed at a position corresponding to the insertion hole 613, so as to improve the assembling strength of the drag chain 50. An insertion column 711 matched with the connecting hole 533 is arranged in the second insertion port 71, and a guide surface 712 is further formed on the rear side of the insertion column 711, so as to facilitate the assembly of the drag chain 50. Furthermore, a stop block 713 is formed in the second insertion port 71, and the stop block 713 is matched with the baffle 532 of the chain link 53, so that dislocation of the connecting hole 533 in the corresponding chain link 53 when the connecting hole is inserted into the insertion column 711 can be avoided, and assembly errors and component damage can be reduced. Of course, the first plug-in connection 61 can also be provided with a corresponding stop.

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 posts 534, i.e., the predetermined rotation axes between the adjacent links 53, extend in the horizontal direction. However, in actual assembly, due to the different fixing positions of the wiring box 60 and the mounting box 70, the second insertion opening 71 is often located closer to the side wall 11 of the compartment 10, and thus torsional stress occurs between adjacent links 53 in the drag chain 50, which increases wear and noise. In order to overcome the above problem, a predetermined rotation axis between the adjacent links 53 is disposed to be deviated in the height direction, and a deviation angle β of the predetermined rotation axis with respect to the horizontal direction is preferably set to be 5 ° to 10 °. The drag chain 50 extends from the first socket 61 backwards, then bends and extends upwards and towards the sidewall 11, and then is connected to the second socket 71. In other words, the bent portion of the drag chain 50 is deflected toward the side wall 11 by the deflection of the rotation shaft between the adjacent links 53 (as shown in fig. 5 and 9). The structural design is more compact and reasonable, and the structural optimization design of the mounting box 70 is facilitated.

In order to realize the deflection of the predetermined rotation axis, the first socket 61 and the second socket 71 can be deflected, so that the axial directions of the socket hole 613 and the socket column 711 are deflected relative to the left-right horizontal direction, and the deflection angles of the socket hole 613 and the socket column 711 are the same, so as to better avoid the generation of the corresponding torsional stress on the drag chain 50. That is, the axial directions of the insertion holes 613 and the insertion posts 711 are both set to have a deflection angle β with respect to the left and right horizontal directions.

Here, the mounting box 70 is directly fixed to the side wall 11, the mounting box 70 is correspondingly formed with a mounting surface for abutting against the side wall 11, and a side edge of the second socket 71 forms the aforementioned deflection angle β with respect to the mounting surface. It should be noted that the wiring box 60 is fixed on the supporting frame 23, the deflection of the first socket 61 can be realized by the structural design of at least one of the mounting box 60 and the receiving groove 231 of the supporting frame 23, and it is only necessary to ensure that the deflection angle β is formed in the axial direction of the first socket 613 in the first socket 61 after the assembly is completed.

In summary, the present invention provides the drawer door 20 and the compartment 10 with stable electrical connection through the tow 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/is obliquely arranged according to a set elevation angle, so that the drag chain 50 is effectively prevented from locally falling to interfere with the slide rail assembly 30 and the like, and the abrasion is reduced. Besides, the mounting structure of the drag chain 50 in the refrigerator is more compact and reasonable, and the installation structure is attractive and reliable.
