The door body 200 includes an inner door 210, an outer door 220, at least one connecting assembly 300, and a bottle holder 400. The inner door 210 is disposed on a front side of the box body 100 at a position corresponding to the forward opening, the inner door 210 is provided with an inner door opening 211 extending in a front-rear direction (namely, a direction from one side of the inner door 210 deviating from the storage compartment 110 to one side of the inner door 210 close to the storage compartment 110, that is, a direction of the inner door opening 211 is in the front-rear direction when the inner door 210 partially closes the forward opening), and the inner door 210 is used for opening or partially closing the forward opening (because the inner door 210 has the inner door opening 211, the inner door 210 can only partially close the forward opening). The outer door 220 is disposed on a front side of the inner door 210 at a position corresponding to the inner door opening 211, and used for opening or closing the inner door opening 211. The refrigerator 10 having the door body 200 can reduce leakage of cooling energy, and the refrigerator 10 having the door body 200 is generally also called a door-in-door refrigerator. An inner surface 221 of the outer door is planar, which makes the outer door 220 have a better appearance and facilitates the production and processing of the outer door 220. The at least one connecting assembly 300 is fixed to the inner surface 221 of the outer door and projects from the inner surface 221 of the outer door. The bottle holder 400 is fixed to the at least one connecting assembly 300. Existing door bodies having an inner door and an outer door are generally provided with a door lining on an inner surface of the outer door, and such door bodies are complicated in structure and not high in production efficiency. However, the outer door 220 and the connecting assembly 300 of the door body 200 of this embodiment of the present invention can be produced separately, and assembled after being produced, thereby improving the production efficiency. The outer door 220 can include an outer shell 222 and an inner shell assembly 223 located at a rear side of the outer shell 222 and connected to the outer shell 222. The outer door 220 is divided into the outer shell 222 and the inner shell assembly 223, which can facilitate production of the outer door 220, and improves the production efficiency. The outer shell 222 and the inner shell assembly 223 define a foaming space 224, and the foaming space 224 can be used for filling a foaming material, thereby improving a thermal insulation effect of the refrigerator 10. A surface of the inner shell assembly 223 close to the inner door 210 is the inner surface 221 of the outer door. A region of the inner shell assembly 223 corresponding to each connecting assembly 300 is provided with a fixing opening 225, and each connecting assembly 300 includes a fixing frame 310, and the fixing frame 310 has a fixing portion 311 disposed in the foaming space 224 and a protruding portion 312 connected to the fixing portion 311 and protruding from the corresponding fixing opening 225. Due to this disposing mode, the connecting assembly 300 is fixed to the outer door 220 more firmly, and therefore this door body 200 is more stable in structure.
