[0038] Specifically, the peripheral wall 23 comprises a front wall extending downwardly from the front end of the top wall 22, a rear wall extending downwardly from the rear end of the top wall 22, and side walls extending downwardly from the left and right ends of the top wall 22, respectively. The side walls are arc-shaped walls, and the connection parts between the side walls and the top wall 22 are smoothly transitioned, thereby enhancing the appearance effect of the refrigeration device 100.

[0039] Further, the top cover 2 has a receiving box 24 connected to the periphery of the display window 21 and located inside the top cover 2, which is used to receive the display screen 3, after the display screen 3 is installed in the receiving box 24, the display surface (upper surface) of the display screen 3 is flush with the display window 21, which can display upwardly and also can close the display window 21, improving the appearance effect of the refrigeration device 100.

[0040] Specifically, the top cover 2 is concave downwardly at the position corresponding to the display window 21, while forming the receiving box 24 and the display window 21, simplifying the preparation process of the refrigeration device 100.

[0041] Further, the receiving box 24 has a wire hole 241, so that the wire harness led out of the box can pass through the wire hole 241 and be electrically connected with the display screen 3, providing electrical transmission signal for the display screen 3, facilitating the electrical connection between the display screen 3 and the box, simple wiring, and convenient maintenance.

[0042] Further, the refrigeration device 100 further comprises a connecting structure for fixing the top cover 2 to the box shell 1, the connecting structure comprises first and second connecting structures arranged on opposite sides of the top cover 2, which enhances the fixing strength of the top cover 2.

[0043] In a specific embodiment, the first connecting structure comprises a connecting hole 4 arranged on the top of the box shell 1, a connecting column 5 arranged in the connecting hole 4, and a buckle 6 arranged on the top cover 2 and matched with the connecting column 5, which is clamped on the connecting column 5 through the buckle 6, so as to realize the fixed connection between one end of the top cover 2 and the box shell 1. Of course, it is not limited thereto.

[0044] The connecting column 5 comprises a sealing sheet 51 and a clamping block 52 arranged on the upper side of the sealing sheet 51 and spaced apart from the sealing sheet 51, the clamping block 52 and the sealing sheet 51 form a receiving groove for receiving the edge of the connecting hole 4 in the box shell 1, so as to fix the connecting column 5 on the box shell 1.

[0045] Specifically, the number of the clamping block 52 is two, and the two clamping blocks 52 are arranged on opposite ends, the connecting hole 4 has an avoiding groove matched with the two clamping blocks 52, during installation, the sealing sheet 51 is first installed to the lower side of the box shell 1, at the same time, the two clamping blocks 52 are first partially received in the avoiding groove, then the connecting column 5 is rotated, so that the clamping block 52 is dislocated with the avoiding groove, at the same time, part of the edge of the connecting hole 4 is located between the clamping block 52 and the sealing sheet 51, which is simple and convenient to install.

[0046] Meanwhile, after the connecting column 5 is fixed, the sealing sheet 51 can seal the connecting hole 4 to prevent material leakage during foaming and affect the foaming effect.

[0047] Specifically, the buckle 6 has a buckle opening 61, and the connecting column 5 has a buckle slot 53 matched with the buckle opening 61. The buckle opening 61 is a concave arc type with an opening. During installation, the buckle opening 61 is inserted into the buckle slot 53, and the installation is convenient.

[0048] In a specific embodiment, the first connecting structure and the second connecting structure are arranged on the front and back sides of the top cover 2.
