[0002] At present, existing refrigerators usually have a drainage hole opened at the lowest point of the inner liner, so that the defrosting water in the inner liner can be discharged into the water receiving tray in the area where the compressor is located through this drainage hole. However, during the defrosting process of the refrigerator, defrosting water is generated. When the defrosting water is discharged through the drainage hole, because there are easily residual water droplets at the drainage hole, during the refrigeration process of the refrigerator, due to the relatively low temperature, the water remaining at the drainage hole will freeze into frost, and the frosting of the water will block the drainage hole, ensuring that the inner liner cavity is not communicated with the outside, which will cause difficulty in opening the refrigerator door. Summary of the Utility Model

[0017] It can be understood that by using the insertion fit between the extension boss and the main drain pipe as a guide to guide the connecting plate to abut against the wall of the inner tank, the accuracy of the assembly position of the connecting plate on the wall of the inner tank can be ensured, thus facilitating the assembly of the drain pipe group on the wall of the inner tank.
[0018] In one embodiment, the main drain pipe has a drain pipe section, and the first through hole and the second through hole are communicated with the drain pipe section in parallel;
[0019] Wherein, the drain pipe section extends downward along the height direction of the inner tank.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0043] Such as Figure 1 , Figure 4 and Figure 7As shown in the figure, the inner liner drainage assembly 100 provided by the present application includes an inner liner 10 and a drainage pipe group 20. An accommodation cavity 101 is formed inwardly in the inner liner 10. A first through hole 111 and a second through hole 112 are formed on the wall 11 of the inner liner 10. The first through hole 111 and the second through hole 112 are respectively communicated with the accommodation cavity 101. Among them, the first through hole 111 is arranged below the second through hole 112 in the height direction of the inner liner 10; the drainage pipe group 20 is fixedly connected to the wall 11. The drainage pipe group 20 includes a main drainage pipe 21 and a connecting branch pipe 22. The connecting branch pipe 22 is connected and communicated with the main drainage pipe 21; among them, the main drainage pipe 21 is communicated with the first through hole 111, and the connecting branch pipe 22 is communicated with the second through hole 112.
[0044] As can be seen from the above, when the inner liner drainage assembly 100 of the present application is applied to a refrigerator (not shown in the figure), since the first through hole 111 is arranged above the second through hole 112, the inner liner 10 can use the first through hole 111 to drain defrosting water and the second through hole 112 to ventilate. Moreover, during the defrosting and refrigeration processes of the refrigerator, the second through hole 112 will not be accumulated with water and frosted, so as to ensure that the inner liner 10 can always communicate with the outside through the second through hole 112 and ensure that the pressure difference inside and outside the inner liner 10 is consistent, thereby reducing the opening force required to open the inner liner 10.
[0045] As Figures 4 to 6 shown, the first through hole 111 is arranged at the lowest point in the height direction of the inner liner 10 of the inner liner 10, and the defrosting water inside the inner liner 10 can drain downward through the first through hole 111. That is to say, the inner liner 10 can drain defrosting water through the main drainage pipe 21, which can meet the use requirement of draining defrosting water outside the inner liner 10. Here, the first through hole 111 is circular, and the circular shape can facilitate the processing and generation of the first through hole 111 on the wall 11 of the inner liner 10. It can be understood that in other embodiments, the first through hole 111 can also be square, triangular, or other irregular shapes.
[0046] Preferably, as Figure 6 shown, the aperture of the first through hole 111 is larger than the aperture of the second through hole 112, so as to meet the use requirement that when the inner liner 10 drains defrosting water, the first through hole 111 can be used to drain defrosting water and the second through hole 112 can be used to ventilate. Here, the second through hole 112 is also circular to facilitate the processing and generation of the second through hole 112 on the wall 11 of the inner liner 10. Of course, the first through hole 111 can also be square, triangular, or other irregular shapes.
[0047] As Figure 3 、 Figure 7 and Figure 8As shown, the main drain pipe 21 has a drain pipe section 211 that extends downward along the height direction of the inner tank 10. This enables the main drain pipe 21 to be connected and communicated with an external pipeline using the drain pipe section 211, facilitating the assembly connection between the external pipeline and the drain pipe group 20. Here, the first through-hole 111 and the second through-hole 112 are connected to the drain pipe section 211 in parallel.
[0048] As Figure 1 , Figure 3 , Figure 7 and Figure 8 shown, the drain pipe group 20 further includes a connecting plate 23. The main drain pipe 21 and the connecting branch pipes 22 are both connected to the connecting plate 23, and the connecting plate 23 abuts against and is connected to the tank wall 11. That is to say, the drain pipe group 20 can be assembled to the tank wall 11 of the inner tank 10 through the connecting plate 23, and the communication between the main drain pipe 21 and the first through-hole 111, and between the connecting branch pipes 22 and the second through-hole 112 can be achieved, facilitating the assembly of the drain pipe group 20 on the tank wall 11 of the inner tank 10. Here, the main drain pipe 21, the connecting branch pipes 22, and the connecting plate 23 are connected as a whole, facilitating the production and preparation of the drain pipe group 20. It should be noted that in the drain pipe group 20 of this embodiment, the connecting branch pipes 22 are U-shaped.
[0049] Preferably, the connecting plate 23 is connected to the tank wall 11 by welding, and the connecting plate 23 is hermetically connected to the tank wall 11. This ensures the sealing of the communication between the main drain pipe 21 and the first through-hole 111, and between the connecting branch pipes 22 and the second through-hole 112 while the connecting plate 23 is assembled on the tank wall 11 of the inner tank 10. It should be noted that the connecting plate 23 can be specifically welded to the tank wall 11 in a circle around the positions corresponding to the first through-hole 111 and the second through-hole 112.
[0050] As Figure 5 , Figure 6 shown, an extending boss 113 is formed on the tank wall 11. The extending boss 113 is arranged around the first through-hole 111, and the extending boss 113 can pass through the connecting plate 23 and be inserted and matched with the main drain pipe 21. That is to say, when the drain pipe group 20 needs to be assembled to the tank wall 11 of the inner tank 10, with the insertion and matching between the extending boss 113 and the main drain pipe 21 as a guide, the connecting plate 23 is guided to abut against the tank wall 11, ensuring the accuracy of the assembly position of the connecting plate 23 on the tank wall 11, thus facilitating the assembly of the drain pipe group 20 on the tank wall 11 of the inner tank 10. Here, the above-mentioned extending boss 113 can be formed when the inner tank 10 punches the first through-hole 111 on the tank wall 11.
[0051] In addition, the present application also provides a refrigerator, including the inner liner drainage assembly 100 described above.
[0052] As Figures 1 to 3 shown, the refrigerator further includes a housing cover 200. A plugging hole 210 is formed in the housing cover 200, and the main drainage pipe 21 can pass through the plugging hole 210 and extend downward. Among them, a diameter-expanded convex portion 212 is formed on the main drainage pipe 21. The diameter-expanded convex portion 212 is arranged above the housing cover 200 in the height direction of the inner liner 10. Moreover, the diameter-expanded convex portion 212 can abut against the housing cover 200 downward, so as to assemble the main drainage pipe 21 on the housing cover 200, thereby facilitating the assembly of the drainage pipe group 20 in the refrigerator. Here, the drainage pipe section 211 of the main drainage pipe 21 passes through the plugging hole 210 of the housing cover 200 and extends downward. It should be noted that the above-mentioned housing cover 200 is the housing cover of the area where the refrigerator compressor is located.
[0053] In summary, during the defrosting and refrigeration processes of the refrigerator provided by the present application, the inner liner 10 can drain the defrosting water through the first through hole 111 and breathe through the second through hole 112. During this process, it is ensured that the second through hole 112 will not be accumulated with water and frosted, so that the inner liner 10 can always communicate with the outside through the second through hole 112 and ensure that the pressure difference inside and outside the inner liner 10 is consistent, thereby reducing the opening force required to open the door of the inner liner 10.
[0054] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0055] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as appropriate changes and variations are made to the above embodiments within the spirit of the present invention, they fall within the scope of the present invention claimed.
