The invention provides a refrigerator with a bottle base convenient to install and dismount. The refrigerator comprises a refrigerator body, a door body matched with the refrigerator body, the bottlebase, and a fixing module for mounting the bottle base on the door body; grooves are concavely formed in the left and right sides of the inner side of the door body; the fixing module comprises a convex block backwards projected from the back side of a bottle base body, extension blocks movably arranged in the grooves and capable of switching between first positions allowing the extension blocks to partially extend out of the grooves and second positions allowing the extension blocks to totally shrink into the grooves, and a driving unit for driving the extension blocks to switch between the first positions and the second positions; the positions, corresponding to the grooves, of the bottle base are provided with accommodating grooves for accommodating the extension blocks when the extension blocks are located in the first positions; and an accommodating cavity for accommodating the convex block is concavely formed in the inner side of the door body. The bottle base is convenient to install and dismount; and meanwhile, after the bottle base is installed, the convex block and the extension blocks commonly bear the bottle base to improve the fixing stability of the bottle base.
