In this way, when the door structure closes the opening of the cabinet 100, the curvature of the first door 200 is the same as the curvature of the center beam 500, thereby improving the aesthetics.

[0102] In some embodiments, when the door structure completely closes the opening of the cabinet 100 , the curvature of the central beam 500 is the same as the curvature of the curved section 202 of the first door 200 .

[0103] In some embodiments, a handle is provided on the first door body 200. The handle facilitates pushing and pulling by the user.

[0104] In some embodiments, a plurality of door structures are provided, and the number of sliding structures is the same as the number of door structures and is provided one by one. The user can open the opening of the cabinet 100 through the plurality of door structures. The provision of the plurality of door structures can reduce the weight of the first door 200 and the second door 300 in a single door structure, thereby reducing the pressure between them and the corresponding slides, thereby reducing the friction, and further facilitating the user to open the door structure.

[0105] In some embodiments, when the number of door structures is greater than one, a central beam 500 is provided at the opening of the cabinet 100, and the number of the central beams 500 is the number of the door structures minus one.

[0106] In some embodiments, when a center beam 500 is provided, the center beam 500 is provided between any two adjacent door structures, and the slideway in the sliding structure is used to be provided on the corresponding center beam 500. The center beam 500 is used to facilitate the provision of the door structure.

[0107] In some embodiments, the sliding structure on the middle beam 500 is arranged in the form that the first slide 600, the second slide 700, the third slide 800 and the fixing groove 850 are all arranged on the middle beam 500. And the length direction of the first slide 600, the second slide 700, the third slide 800 and the fixing groove 850 is the same as the length direction of the middle beam 500.

[0108] Furthermore, the first slide track 600 , the second slide track 700 , the third slide track 800 and the fixing groove 850 are all arranged on a side of the center beam 500 facing the corresponding door structure.

[0109] In some embodiments, if the number of the door structures is greater than one, the multiple door structures are arranged at intervals along the length direction of the opening of the cabinet 100 .

[0110] In some embodiments, the edge of the opening of the cabinet 100 near the front side of the cabinet 100 is lower than the edge of the opening of the cabinet 100 near the back side of the cabinet 100 , so as to facilitate the user to observe the goods inside the cabinet 100 .

[0111] In some embodiments, taking the case that there are two door structures, the two ends of the middle beam 500 are respectively connected to the top of the front side of the cabinet 100 and the top of the rear side of the cabinet 100, and the middle beam 500 spans the opening of the cabinet 100. The two sides of the middle beam 500 close to the two ends of the length direction of the cabinet 100 are respectively the first side and the second side, and both sides have a door structure and a sliding structure. In the sliding structure located on the first side, one of the first slides 600 is opened on the side wall of the cabinet 100 facing the first side in the length direction, and the other first slide 600 is opened on the first side of the middle beam 500, and the second slide 700 and the third slide 800 are the same. In the sliding structure located on the second side, one of the first slides 600 is opened on the side wall of the cabinet 100 facing the second side in the length direction, and the other first slide 600 is opened on the second side of the middle beam 500, and the second slide 700 and the third slide 800 are the same.

[0112] In some embodiments, the third slide 800 is located above the second slide 700, and the second slide 700 is located above the first slide 600; the first slide 600 is inclined upward from one end facing the rear side of the cabinet 100. This design is used to limit the moving distance of the first slide 600. When the second roller 110 moves to the inclined position of the first slide 600, the second roller 110 will drive the horizontal section 201 of the first door body 200 to move upward. At this time, the horizontal section 201 will abut against the second door body 300. Because the third slide 800 limits the movement of the second door body 300 in the height direction, the movement of the first door body 200 is indirectly limited, thereby realizing the limitation of the sliding distance of the first door body 200, and there is no need to set a limiter separately, saving costs.

[0113] In some embodiments, a first heat exchanger, a second heat exchanger and a compressor are disposed inside the cabinet 100, and the first heat exchanger, the second heat exchanger and the compressor are connected and communicated. The refrigerant is transported to the first heat exchanger and the second heat exchanger by the compressor, and the refrigerant flows in the first heat exchanger and the second heat exchanger to perform heat conversion.

[0114] Furthermore, the first heat exchanger is close to the interior of the cabinet 100, and the second heat exchanger is far away from the interior of the cabinet 100. The refrigerant enters the second heat exchanger and is cooled. The cooled refrigerant enters the first heat exchanger, and the first heat exchanger is cooled. The interior of the cabinet 100 is cooled by the first heat exchanger with a lower temperature.

[0115] In some embodiments, a pressure reducing component is provided between the second heat exchanger and the first heat exchanger. The refrigerant entering the second heat exchanger is in liquid state and has a relatively high temperature. In the second heat exchanger, because the temperature of the refrigerant is higher than the ambient temperature, the refrigerant in the second heat exchanger is cooled. The cooled refrigerant is vaporized after passing through the pressure reducing component. The temperature of the vaporized refrigerant is greatly reduced. The cooled refrigerant enters the first heat exchanger. The first heat exchanger is cooled, and the interior of the cabinet 100 is cooled through the first heat exchanger having a lower temperature. The refrigerant after passing through the first heat exchanger flows back into the compressor and is recompressed into a liquid to realize circulation.

[0116] In some embodiments, a first fan is provided at the first heat exchanger, and the first fan blows airflow toward the first heat exchanger. After the airflow is heated by the first heat exchanger, it flows into the cabinet 100, thereby improving the cooling effect on the interior of the cabinet 100.

[0117] In some embodiments, a second fan is provided at the second heat exchanger, and air from the second fan blows through the second heat exchanger, thereby increasing the contact area and speed between the second heat exchanger and the air, and improving the heat exchange effect between the air and the second heat exchanger, thereby improving the cooling effect of the refrigerant inside the second heat exchanger, and further reducing the temperature of the refrigerant entering the first heat exchanger, thereby improving the cooling effect on the interior of the cabinet 100.

[0118] Through the description of multiple embodiments of the front-to-back sliding three-door refrigerator of the present invention, it can be seen that the front-to-back sliding three-door refrigerator of the present invention has at least one or more of the following advantages:

[0119] 1. The second slide 700, the third slide 800 and the fixing groove 850 are recessed in the inner wall of the cabinet 100 to hide the second slide 700 and the third slide 800, so as to avoid blocking the interior of the cabinet 100. When the refrigerator is viewed from above, the second slide 700, the third slide 800 and the fixing groove 850 are not visible, which reduces the blocking of the goods and facilitates the user to observe the goods inside the refrigerator;

[0120] 2. When the first door body 200 is pushed, the first universal ball 120 and the second universal ball 130 will contact the inner wall of the first slideway 600 and roll, thereby guiding the first door body 200. This avoids the problem of door clamping and deviation when the first door body 200 is pushed.

[0121] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0122] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
