When the drawer body 22 is pushed into the pull-out space, the drawer cover 21 can block the opening at the top of the drawer body 22, thereby forming a relatively closed space in the drawer body 22, so that some food with high requirements for water locking can be placed in the drawer body 22 for storage.

[0077] In the above scheme, the housing 14 and the drawer cover 21 are positioned by the concave-convex matching structure, and the positioning method is simple and efficient, which can effectively limit the modularly designed water supply assembly 10 to prevent it from moving around, greatly improving the stability of the water supply assembly 10, and the water supply assembly 10 can be disassembled and assembled without the help of other auxiliary disassembly and assembly tools through the concave-convex matching method, which is very easy and labor-saving. Therefore, the problems of inconvenient disassembly and assembly, low assembly efficiency, poor stability, and easy movement of the water supply assembly of the existing refrigerator are effectively solved.

[0078] In some embodiments, Figures 4 to 9 As shown, a protrusion structure 140 is provided on the bottom wall of the shell 14, and a groove structure 210 is provided on the drawer cover 21 to be positioned and matched with the protrusion structure 140. Alternatively, in a modified embodiment, a groove structure is provided on the bottom wall of the shell 14, and a protrusion structure is provided on the drawer cover 21 to be positioned and matched with the groove structure. Exemplarily, the protrusion structure 140 can be a structure such as a convex block, a convex column or a convex protrusion, and the groove structure 210 is a groove with a shape and size corresponding thereto. The overall positioning of the water supply assembly 10 is achieved by the concave-convex matching of the protrusion structure 140 and the groove structure 210, and the effective positioning of the water supply assembly 10 can be achieved without opening a hole, and the disassembly and assembly is convenient and efficient.

[0079] In a more preferred implementation of the present embodiment, a protrusion structure 140 is provided on the bottom wall of the shell 14, and a groove structure 210 cooperating therewith is provided on the drawer cover 21. Through the cooperation between the protrusion structure 140 and the groove structure 210, a limiting function can be achieved, so that the module cannot move around after being installed in the spacing space above the drawer cover 21.

[0080] In one implementation of this embodiment, there is one protrusion structure 140 , which is disposed at the center of the bottom wall of the shell 14 ; there is also one groove structure 210 , which is correspondingly disposed at the center of the drawer cover 21 .

[0081] In another preferred implementation of this embodiment, there are two protrusion structures 140 , which are spaced apart on the bottom wall of the housing 14 . There are also two corresponding groove structures 210 , which are spaced apart on the drawer cover 21 corresponding to the protrusion structures 140 .

[0082] The bottom wall of at least one of the left shell 1412 and the right shell 1413 partially protrudes outward to form a protruding structure 140 for positioning, and the drawer cover 21 is recessed downward corresponding to the protruding structure 140 to form a groove structure 210 suitable for positioning and cooperating with the protruding structure 140.

[0083] Preferably, in this embodiment, if Figures 6 to 9 As shown, the edges where the shell bottom wall of the left shell 1412 and the shell bottom wall of the right shell 1413 are connected are both provided with the protruding structures 140. After the left shell 1412 and the right shell 1413 are connected, the two protruding structures 140 can be spliced ​​to form a complete protruding structure 140. The spliced ​​protruding structure 140 is positioned and matched with the groove structure 210 on the drawer cover 21. Compared with only providing the protruding structure 140 on the shell bottom wall of the left shell 1412 and the right shell 1413, the protruding structures 140 provided on the left shell 1412 and the right shell 1413 are inserted and limited in the groove structure 210 respectively. The groove structure 210 can also play the role of restraining and limiting the left shell 1412 and the right shell 1413, thereby improving the stability of the bottom connection between the left shell 1412 and the right shell 1413.

[0084] Preferably, in this embodiment, if Fig. 9 As shown, there are multiple snap-fit ​​structures on both sides of the inner side of the front shell 1411, and there are multiple snap-fit ​​holes 14121. The multiple snap-fit ​​structures are respectively matched with the snap-fit ​​holes 14121 on the shell side walls of the left shell 1412 and the right shell 1413, so as to realize the installation and fixation of the front shell 1411.
