[0056] Please refer to all the drawings. In an illustrative embodiment of the refrigerator of the present invention, the refrigerator comprises: a cabinet body 100, a door structure and a sliding structure; wherein the top of the cabinet body 100 is open.

[0057] The door structure is disposed at the opening of the cabinet 100 ; the door structure includes a first door 200 .

[0058] The sliding structure is disposed at the opening of the cabinet 100 ; the sliding structure includes a first slideway 600 and a second slideway 700 .

[0059] Among them, there are two first slides 600 and two second slides 700 and they are symmetrically arranged; the front ends of both sides of the first door body 200 slide on the first slides 600, and the rear ends slide on the second slides 700; the first slide 600 includes a first sliding section 601, a second sliding section 602, a first arc section 603 and a second arc section 604.

[0060] Among them, the first sliding section 601 is located at the end of the second sliding section 602 close to the front side of the cabinet 100; the second sliding section 602 is located above the first sliding section 601; the first arc section 603 and the second arc section 604 connect the first sliding section 601 and the second sliding section 602; the two ends of the first arc section 603 are respectively tangentially connected to the second arc section 604 and the first sliding section 601; the two ends of the second arc section 604 are respectively tangentially connected to the first arc section 603 and the second sliding section 602.

[0061] Through the above solution, the design of the door structure allows the first door body 200 to move smoothly on the first and second slides 700, thereby realizing convenient opening and closing of the cabinet 100 opening. The design of the first and second slides 700, especially the first arc segment 603 and the second arc segment 604, ensures the stability and smoothness of the first door body 200 when moving. In addition, the arrangement of the first sliding segment 601 and the second sliding segment 602 optimizes the movement path of the first door body 200, so that the first door body 200 is lifted upward when moving to the rear side of the cabinet 100, thereby reducing the obstruction of the cabinet 100 opening and minimizing the space occupied when it is opened, so as to facilitate users to take goods from the inside of the refrigerator.

[0062] In some embodiments, the first door body 200 includes a horizontal section 201 and a curved section 202 connected to each other.

[0063] In some embodiments, first rollers 900 are respectively provided on both sides of the curved section 202, and second rollers 110 are respectively provided on both sides of the horizontal section 201. The two first rollers 900 roll on the two first slideways 600 respectively; and the two second rollers 110 roll on the two second slideways 700 respectively. The arrangement of the first and second rollers 110 further optimizes the movement mechanism of the first door body 200. The configuration of the first roller 900 and the second roller 110 ensures the smooth movement of the first door body 200 on the sliding structure, reduces the friction and resistance during operation, and improves the durability and reliability of the overall structure. This design is not only convenient for user operation, but also ensures the stability and durability of the first door body 200 in long-term use.

[0064] In some embodiments, the center of the first arc segment 603 faces the side away from the bottom of the cabinet 100; the center of the second arc segment 604 faces the side of the bottom of the cabinet 100. The center direction design of the first and second arc segments 604 enhances the guidance and stability of the first door body 200 when moving. By adjusting the center direction of the two curved segments 202, it is ensured that the first door body 200 can slide smoothly from the first sliding segment 601 to the second sliding segment 602. The sliding trajectory of the first door body 200 can be controlled to make it more in line with the user's usage habits, while also improving the stability of the structure and the alignment accuracy of the first door body 200.

[0065] In some embodiments, the radius of the first arc segment 603 is A; the radius of the second arc segment 604 is B; B≤A≤3B is satisfied. The proportional relationship between the radius of the first arc segment 603 and the radius of the second arc segment 604 ensures the smooth movement of the first door body 200 and the spatial efficiency of the entire sliding structure. By precisely controlling the radius of the first arc segment 603 and the second arc segment 604, the movement trajectory of the first door body 200 can be optimized, so that it can stably transition from the first sliding segment 601 to the second sliding segment 602.

[0066] In some embodiments, the ratio of the radius of the first arc segment 603 to the radius of the second arc segment 604 is 2:1, that is, B=2A. Under this size, the movement trajectory of the first door body 200 is optimized.

[0067] In some embodiments, the height difference between the first sliding section 601 and the second sliding section 602 is C; the length of the front-to-back direction of the internal space of the cabinet 100 is D; and 0<C≤D / 32.5 is satisfied. The height difference design between the first sliding section 601 and the second sliding section 602 ensures sufficient space for the first door body 200 to slide, while optimizing the internal layout of the refrigerator. By adjusting the height difference C, the utilization of the internal space of the refrigerator can be maximized, ensuring that the first door body 200 can be lifted to a sufficient height, thereby reducing the obstruction to the opening of the cabinet 100.

[0068] In some embodiments, when C is close to 0, the height to which the first door body 200 is lifted is the smallest, and thus the force required to push the first door body 200 is the smallest.

[0069] In some embodiments, when C is larger, the height to which the first door body 200 is lifted is the largest, so the force required to push the first door body 200 is the largest, but the obstruction of the opening of the cabinet body 100 is the smallest.

[0070] In some embodiments, C=D / 65 is satisfied. The height at which the first door 200 is lifted is optimized at this size. At this size, the sealing of the door structure to the opening of the cabinet 100 is ensured, and the obstruction to the opening of the cabinet 100 is reduced when the first door opens the opening of the cabinet 100. At the same time, the force required to push the first door 200 is moderate at this size.

[0071] In some embodiments, the door structure further includes a second door 300 and a third door 400, the first door 200 is disposed below the second door 300, and the second door 300 is disposed below the third door 400. When opening the cabinet 100, the first door 200 is pushed, and the first door 200 drives the second door 300 to move, so that the second door 300 is located below the third door 400, and the first door 200 is located below the second door 300, thereby realizing the opening of the cabinet 100. When closing the cabinet 100, the first door 200 is pulled, and when the first door 200 moves halfway, the second door 300 is pulled, and finally the first door 200, the second door 300 and the third door 400 close the opening of the cabinet 100.

[0073] In some embodiments, two sides of the second door body 300 slide in the third slideway 800 respectively.

[0074] In some embodiments, two sides of the third door body 400 are respectively disposed in two fixing grooves 850 .

[0075] The addition of the third slideway 800 and the fixing groove 850 further enhances the complexity and functionality of the door structure. The third slideway 800 provides a smooth movement path for the second door 300, while the fixing groove 850 provides a stable support for the third door 400, ensuring the stability and reliability of the entire door structure.

[0076] In some embodiments, the second slide 700, the third slide and the fixing groove 850 are recessed in the inner wall of the cabinet 100. Designing the slide and the fixing groove 850 to be recessed in the inner wall of the cabinet 100 not only optimizes space utilization, reduces internal protruding components, improves the neatness and usability of the internal space of the refrigerator, but also enhances the overall aesthetics of the structure and user experience.
