  • one end of the second accommodating cavity 39 is aligned with the first accommodating cavity 38, such that the rear inner wall of the second accommodating cavity 39 is only located on one transverse side; the rear inner wall of the second accommodating cavity 39 is further provided with a groove which is recessed backwards to accommodate the fixing portion 723, such that a front end surface of the fixing portion 723 is flush with the rear inner wall, and smooth mounting of a display control assembly 6 is guaranteed.
  • the passing hole 36 of the mounting box 3 is provided on a rear side of a part of the second accommodating cavity 39 longer than the first accommodating cavity 38, such that a wire passing hole 72 is approximately located at a middle position of a width of the second accommodating cavity 39 in the transverse direction, thereby better facilitating connection of the wire harness and the display control circuit board 62; that is, a difference of lengths of the wire harnesses connected to the display control circuit board 62 is less, tidying and an arrangement are easier, and selection of the display control circuit board 62 is wider.
  • the fixing portion 723 on the other side in the transverse direction is fitted with a protrusion 316 protruding from the mounting box 3, and the protrusion 316 is also provided with the fixing hole 315, such that a fixing effect of the mounting base 7 can be effectively guaranteed by the first elastic portion 79, the second elastic portion 721, the fixing portion 723 and the fixing hole 315.
  • the refrigerator further comprises appearance parts 8 provided on left and right sides of the display control assembly 6, and the appearance parts 8 are fixed on the reinforcing beam 22, thus preventing the reinforcing beam 22 from being exposed, and improving the aesthetic degree.
  • the appearance parts 8 on the left and right sides have inconsistent sizes, and the appearance part 8 on a door hinge side is smaller.
  • the display control assembly 6 comprises a display control bracket 61 integrally formed on the front side of the mounting base 7, a display control circuit board 62 fixed on a rear side of the display control bracket 61, and a display control panel 63 covering a front side of the display control bracket 61.
  • the front wall of the mounting base 7 and the display control bracket 61 are configured as the same structure, such that the main control board 4 and the display control circuit board 62 can be fixed conveniently, more materials are saved, and the cost is effectively reduced.
  • the display control circuit board 62 is provided between the display control bracket 61 and the main control board 4 and located in the inner mounting cavity 71, such that the display circuit board can be directly connected with the main control board 4 in the inner mounting cavity 71, a distance between the display circuit board and the main control board is shorter, and the wire harness connecting the display circuit board and the main control board is not required to penetrate out of the mounting base 7 forwards, thereby reducing wire harness tidying difficulty.
  • the display control panel 63 and the display control bracket 61 are also fixed together, during disassembly and repair, a fixing structure between the display control panel 63 and the mounting box 3 can be directly released, and then, the display control panel 63 can be directly pulled out. Therefore, the main control board 4 can be taken out in one step, and the repair steps are greatly simplified.
  • the mounting base 7 and the mounting box 3 are fixed only by the above-mentioned positioning structure, the fixing tab 723 and the screw hole 315 of the mounting base 7 are not fixed by a screw, or the fixing tab 723 and the screw hole 315 are not necessarily provided.
  • the mounting box 3 is provided between the inner container 1 and the housing 2, the main control board 4 is provided in the mounting box 3, and the mounting box 3 has the opening 31 opened forwards for mounting and dismounting the main control board 4. Therefore, during repair, the display control assembly 6 on the front side of the mounting box 3 can be directly detached, and then, the main control board 4 is pulled out forwards, which greatly simplifies repair steps, reduces a repair time, reduces a repair cost, and meanwhile is not prone to damage to the refrigerator or an object around the refrigerator, and improves user experiences.
