[0003] In the prior art, the opening of the refrigerator is located at the top, and a door body is provided at the opening of the refrigerator. The structure of the door body is left and right sliding doors. For refrigerators longer than 2m, the friction is too great because the door body is too large and heavy. Customers report that it is difficult to push and pull during use, which affects consumers' shopping. Utility Model Content

[0004] In view of the shortcomings in the related art, the utility model provides a refrigerator, which closes the opening of the machine body by means of a first door panel, a second door panel and a third door panel, wherein the contact area between the first door panel, the second door panel and the third door panel and the slideway is small, thereby reducing friction and facilitating opening by users. When the user opens or closes the door structure, the user can push forward or pull backward the first door panel at the front side of the machine body, thereby facilitating the user to exert force, thereby facilitating the user to open or close the opening of the machine body and improving the user experience.

[0005] The invention solves the technical problem in the prior art that it is laborious for a user to open or close the opening of the machine body.

[0006] The utility model provides a refrigerator, comprising:

[0007] A machine body, wherein the top of the machine body is open;

[0008] A door structure, the door structure is arranged at the opening of the machine body; the door structure comprises a first door panel, a second door panel and a third door panel, the first door panel is arranged below the second door panel, and the second door panel is arranged below the third door panel; the first door panel is bent from the direction close to the front side of the machine body toward the bottom of the machine body;

[0009] A sliding structure, the sliding structure is arranged at the opening of the body; the sliding structure comprises a plurality of slideways which are symmetrically and spaced apart, and the length direction of the slideways is arranged along the front-rear direction of the body;

[0010] Both sides of the first door panel and the second door panel slide in the corresponding slideways respectively.

[0011] In the technical solution, the opening of the machine body is closed by the first door panel, the second door panel and the third door panel, and the contact area between the first door panel and the second door panel and the slideway is small, which reduces friction and is convenient for users to open. When the user opens or closes the door structure, the user can push forward or pull backward the first door panel at the front side of the machine body, which is convenient for the user to exert force, thereby facilitating the user to open or close the opening of the machine body and improving the user experience.

[0012] In some embodiments, the second door panel and the third door panel are both straight panels, the first door panel includes a horizontal section and a curved section connected to each other, and when the door body structure closes the opening of the body, the third door panel is close to the rear side of the body, and the curved section of the first door panel is close to the front side of the body; the second door panel is arranged between the third door panel and the first door panel.

[0013] In the technical solution, the curved section of the first door panel facilitates the user to observe the goods inside the machine body from the front side of the machine body.

[0014] In some embodiments, the sliding structure includes a first slideway, a second slideway and a third slideway; the first slideway, the second slideway and the third slideway each have two and are symmetrically arranged;

[0015] First rollers are respectively arranged on both sides of the curved section, second rollers are respectively arranged on both sides of the horizontal section, the two first rollers roll on the two first slides respectively; the two second rollers roll on the two second slides respectively; the two sides of the second door panel slide on the two third slides respectively.

[0016] In the technical solution, the friction between the first door panel and the first slideway and the second slideway is reduced by the first roller and the second roller, so as to further facilitate the user to open the first door panel.

[0017] In some embodiments, the third slide is located above the second slide, and the second slide is located above the first slide; the first slide is inclined upward from one end facing the rear side of the body.

[0018] In the technical solution, this design is used to limit the moving distance of the first slide. When the second roller moves to the inclined position of the first slide, the second roller will drive the horizontal section of the first door panel to move upward. At this time, the horizontal section will abut against the second door panel. Because the third slide limits the movement of the second door panel in the height direction, it indirectly limits the movement of the first door panel, thereby achieving the limitation of the sliding distance of the first door panel. There is no need to set a limiting component separately, saving costs.

[0019] In some embodiments, a first sealing strip is disposed on a side wall of the third door panel facing the second door panel, and a second sealing strip and a third sealing strip are disposed on both sides of the second door panel, respectively.

[0021] In some embodiments, a first blocking block is provided at one end of the horizontal section facing the rear side of the body;

[0022] A second blocking block and a third blocking block are respectively provided at two ends of the second door panel on a side facing the first door panel; and the first blocking block is located between the second blocking block and the third blocking block.

[0023] In the technical solution, when the first door panel is pushed to open the opening of the machine body, the first blocking block contacts the second blocking block, and the first blocking block pushes the second blocking block, so that the second door panel moves with the first door panel to open the opening of the machine body. When the first door panel is pulled to close the opening of the machine body, the first blocking block contacts and pushes the third blocking block, so that the second door panel moves with the first door panel to close the opening of the machine body. The user can drive the movement of the second door panel by only pushing and pulling the first door panel, which is convenient for the user to open or close the opening of the machine body.

[0024] In some of the embodiments, the door body structures are provided in plurality, and the number of the sliding structures is the same as the number of the door body structures and are provided in one-to-one correspondence.

[0025] In the technical solution, the user can open the opening of the machine body through multiple door structures. The arrangement of multiple door structures can reduce the weight of the first door panel and the second door panel in a single door structure, thereby reducing the pressure between them and the corresponding slideway, thereby reducing friction, and further facilitating the user to open the door structure.

[0026] In some embodiments, when the number of the door body structures is greater than one, a center beam is provided at the opening of the machine body, and the number of the center beams is the number of the door body structures minus one. The center beam is provided between any two adjacent door body structures, and the slideway in the sliding structure is used to be provided on the corresponding center beam.

[0027] In the technical solution, a central beam is used to facilitate the arrangement of the door structure.

[0028] In some embodiments, the length direction of the middle beam is arranged along the front-rear direction of the machine body, and one end of the middle beam close to the front side of the machine body is bent toward the bottom of the machine body.

[0029] In the technical solution, this can ensure that when the door structure closes the opening of the machine body, the curvature of the first door panel is the same as the curvature of the center beam, thereby improving the aesthetics.

[0030] In some embodiments, a handle is provided on the first door panel.

[0031] In the technical solution, the handle is used to facilitate users to push and pull.

[0032] Based on the above technical solution, in the embodiment of the utility model, the first door panel, the second door panel and the third door panel are used to close the opening of the machine body, and the contact area between the first door panel and the second door panel and the slideway is small, which reduces friction and is convenient for users to open. When the user opens or closes the door structure, the user can push forward or pull backward the first door panel at the front side of the machine body, which is convenient for the user to exert force, thereby facilitating the user to open or close the opening of the machine body and improving the user experience.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Please refer to all the accompanying drawings. In an illustrative embodiment of the refrigerator of the present invention, the refrigerator includes: a body 100, a door structure and a sliding structure, wherein the top of the body 100 is open; the door structure is arranged at the opening of the body 100; the door structure includes a first door panel 200, a second door panel 300 and a third door panel 400, the first door panel 200 is arranged below the second door panel 300, and the second door panel 300 is arranged below the third door panel 400; the first door panel 200 is bent from the direction close to the front side of the body 100 to the bottom of the body 100; the sliding structure is arranged at the opening of the body 100; the sliding structure includes a plurality of symmetrical and spaced slides, and the length direction of the slides is arranged along the front and rear direction of the body 100.

[0051] Both sides of the first door panel 200 and the second door panel 300 slide in corresponding slideways respectively.

[0052] In the above scheme, the opening of the machine body 100 is closed by the first door panel 200, the second door panel 300 and the third door panel 400. The contact area between the first door panel 200, the second door panel 300 and the third door panel 400 and the slideway is small, which reduces friction and is convenient for users to open. When the user opens or closes the door structure, the user pushes the first door panel 200 forward or pulls the first door panel 200 backward at the front side of the machine body 100, and the first door panel 200 drives the second door panel 300 to move to open or close the opening of the machine body 100, which is convenient for users to exert force, thereby facilitating users to open or close the opening of the machine body 100 and improving user experience.

[0053] In some embodiments, the body 100 is rectangular, so the opening of the body 100 is also rectangular. The width direction of the body 100 is from the front side to the rear side. The length direction of the slide is set along the width direction of the body 100. Therefore, in the present application, the first door panel 200, the second door panel 300 and the third door panel 400 slide along the width direction of the opening of the body 100. In the prior art, the slide is set along the width direction of the opening of the body 100, and the door body slides through the length direction of the body 100. Therefore, in the prior art, when the door body is opened, the distance between the door body and the slide is long, and the friction force is large. In the present application, when the first door panel 200, the second door panel 300 and the third door panel 400 are opened, the friction distance with the slide is short, the friction force is small, and it is convenient for users to open the opening of the body 100.

[0054] Take the opening of the body 100 as an example, the length is 3 meters and the width is 1.5 meters. In the prior art, the opening of the body 100 has three door bodies, and slides along the length direction of the body 100. If the opening of the body 100 needs to be opened by one-third, the door body needs to be pushed to slide for 1 meter. In the present application, the first door panel 200 is pushed along the slide in the width direction of the body 100, and only 0.5 meters is needed to slide to open the opening of the body 100 by one-third. In the present application, the distance that the user needs to push the first door panel 200 is much smaller than that in the prior art, which is convenient for users to use.

[0055] In some embodiments, the second door panel 300 and the third door panel 400 are both straight panels, the first door panel 200 includes a horizontal section 201 and a curved section 202 connected to each other, and when the door structure closes the opening of the machine body 100, the third door panel 400 is close to the rear side of the machine body 100, and the curved section 202 of the first door panel 200 is close to the front side of the machine body 100; the second door panel 300 is arranged between the third door panel 400 and the first door panel 200. Through the curved section 202 of the first door panel 200, it is convenient for users to observe the goods inside the machine body 100 from the front side of the machine body 100.

[0056] Furthermore, the opening of the curved section 202 faces the interior of the machine body 100. The axial length of the curved section 202 is the same as the length direction of the opening of the machine body 100.

[0057] 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-to-one. The user can open the opening of the machine body 100 through the plurality of door structures. The provision of the plurality of door structures can reduce the weight of the first door panel 200 and the second door panel 300 in a single door structure, thereby reducing the pressure between them and the corresponding slideway, thereby reducing the friction, and further facilitating the user to open the door structure.

[0058] In some embodiments, when the number of door structures is greater than one, a middle beam 500 is provided at the opening of the machine body 100, and the number of the middle beams 500 is the number of door structures minus one, and the middle beams 500 are provided between any two adjacent door structures, and the slideways in the sliding structure are used to be provided on the corresponding middle beams 500. The middle beams 500 are used to facilitate the provision of the door structures.

[0059] 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 body 100 .

[0060] In some embodiments, the edge of the opening of the body 100 close to the front side of the body 100 is lower than the edge of the body 100 close to the back side of the body 100, so as to facilitate users to observe the goods inside the body 100.

[0061] In some embodiments, the sliding structure includes a first slide 600, a second slide 700, and a third slide 800; there are two first slides 600, two second slides 700, and three slides 800, and they are symmetrically arranged; first rollers 900 are respectively arranged on both sides of the curved section 202, and second rollers 110 are respectively arranged on both sides of the horizontal section 201, and the two first rollers 900 roll on the two first slides 600; the two second rollers 110 roll on the two second slides 700; and the two sides of the second door panel 300 slide on the two third slides 800. The friction between the first door panel 200 and the first slide 600 and the second slide 700 is reduced by the first roller 900 and the second roller 110, which further facilitates the user to open the first door panel 200.

[0062] In some embodiments, if there is only one door structure, the first slideway 600, the second slideway 700 and the first third slideway are respectively opened on both sides of the length direction of the opening of the machine body 100. The heights of the two corresponding first slideways 600 are the same, the heights of the two corresponding second slideways 700 are the same, and the heights of the two corresponding third slideways 800 are the same. After the door structure is installed, the horizontal section 201 of the first door panel 200, the second door panel 300 and the third door panel 400 are parallel to each other.

[0063] Please refer to all the drawings. 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 machine body 100 and the top of the rear side of the machine body 100, and the middle beam 500 spans the opening of the machine body 100. The two sides of the middle beam 500 close to the two ends of the length direction of the machine body 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 machine body 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 machine body 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.

[0064] 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 body 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 panel 200 to move upward. At this time, the horizontal section 201 will abut against the second door panel 300. Because the third slide 800 limits the movement of the second door panel 300 in the height direction, the movement of the first door panel 200 is indirectly limited, thereby realizing the limitation of the sliding distance of the first door panel 200, and there is no need to set a limiter separately, saving costs.

[0065] In some embodiments, the side wall of the third door panel 400 facing the second door panel 300 is provided with a first sealing strip, and the second sealing strip and the third sealing strip are respectively provided on both sides of the second door panel 300. When the first door panel 200, the second door panel 300 and the third door panel 400 generate relative movement, the gaps between the first door panel 200, the second door panel 300 and the third door panel 400 are sealed by the first sealing strip, the second sealing strip and the third sealing strip, thereby reducing the loss of cold air inside the machine body 100.

[0066] In some embodiments, the front-to-back direction of the machine body 100 is defined as a reference direction, and the first sealing strip is disposed on the side of the third door panel 400 facing the second door panel 300. The length direction of the first sealing strip is disposed along the length direction of the opening of the machine body 100, that is, the length direction of the first sealing strip is perpendicular to the sliding direction of the third door panel 400, and the first sealing strip is attached to the upper surface of the second door panel 300. When the second door panel 300 and the third door panel 400 slide relative to each other, the gap between the second door panel 300 and the third door panel 400 is closed by the first sealing strip, and the upper surface of the second door panel 300 can be cleaned by the first sealing strip.

[0067] In some embodiments, the second sealing strip is disposed on one end of the second door panel 300 facing the third door panel 400 and close to the rear side of the machine body 100. The second sealing strip is parallel to the first sealing strip, and the second sealing strip is attached to the lower surface of the third door panel 400. When the second door panel 300 and the third door panel 400 slide relative to each other, the gap between the third door panel 400 and the second door panel 300 is sealed by the second sealing strip, and the lower surface of the third door panel 400 can be cleaned by the second sealing strip.

[0068] In some embodiments, the third sealing strip is disposed on one end of the second door panel 300 that faces the first door panel 200 and is close to the front side of the machine body 100. The third sealing strip is parallel to the first sealing strip, and the third sealing strip is attached to the upper surface of the first door panel 200. When the second door panel 300 and the first door panel 200 slide relative to each other, the gap between the upper surface of the first door panel 200 and the second door panel 300 is sealed by the third sealing strip.

[0069] In some embodiments, a fourth sealing strip is disposed on the upper surface of the first door panel 200 and at one end facing the rear side of the machine body 100, the fourth sealing strip is parallel to the first sealing strip, and the fourth sealing strip is attached to the lower surface of the second door panel 300. When the second door panel 300 and the first door panel 200 slide relative to each other, the gap between the second door panel 300 and the first door panel 200 is sealed by the fourth sealing strip.

[0070] In some embodiments, the specific structures of the first sealing strip, the second sealing strip, the third sealing strip and the fourth sealing strip include but are not limited to brushes and rubber strips.

[0071] In some embodiments, the first door panel 200 includes a first frame and a first perspective panel, the first perspective panel is arranged inside the first frame, the fourth sealing strip is arranged on the first frame, and the first roller 900 and the second roller 110 are both rotatably connected to the first frame.

[0072] In some embodiments, the second door panel 300 includes a second frame and a second perspective panel, the second perspective panel is disposed inside the second frame, and the second sealing strip and the third sealing strip are disposed on the second frame.

[0073] In some embodiments, the third door panel 400 includes a third frame and a third perspective panel, the third perspective panel is disposed inside the third frame, and the first sealing strip is disposed on the third frame.

[0074] It is understandable that the materials of the first perspective plate, the second perspective plate and the third perspective plate are all translucent materials, so that the user can easily observe the goods inside the body 100. The materials of the first perspective plate, the second perspective plate and the third perspective plate include but are not limited to glass, transparent plastic, and transparent resin.

[0075] In some embodiments, a first stopper is provided at one end of the horizontal section 201 facing the rear side of the machine body 100; a second stopper and a third stopper are provided at both ends of the second door panel 300 facing the first door panel 200; and the first stopper is located between the second stopper and the third stopper. When the first door panel 200 is pushed to open the opening of the machine body 100, the first stopper contacts the second stopper, and the first stopper pushes the second stopper, so that the second door panel 300 moves with the first door panel 200 to open the opening of the machine body 100. When the first door panel 200 is pulled to close the opening of the machine body 100, the first stopper contacts and pushes the third stopper, so that the second door panel 300 moves with the first door panel 200 to close the opening of the machine body 100. The user can drive the movement of the second door panel 300 by only pushing and pulling the first door panel 200, so that the user can open or close the opening of the machine body 100 conveniently.

[0076] Further, the second blocking block is disposed at one end of the lower surface of the second door body close to the rear side of the machine body 100. The third blocking block is disposed at one end of the lower surface of the second door body close to the front side of the machine body 100.

[0077] Furthermore, the second blocking block and the third blocking block are arranged on the second frame. The first blocking block is arranged on the first frame.

[0078] In some embodiments, the length direction of the middle beam 500 is arranged along the front-to-back direction of the machine body 100, and one end of the middle beam 500 close to the front side of the machine body 100 is bent toward the bottom of the machine body 100. In this way, when the door structure closes the opening of the machine body 100, the curvature of the first door panel 200 is the same as the curvature of the middle beam 500, thereby improving the aesthetics.

[0079] In some embodiments, when the door structure completely closes the opening of the machine body 100 , the curvature of the middle beam 500 is the same as the curvature of the curved section 202 of the first door panel 200 .

[0080] In some embodiments, a handle is provided on the first door panel 200. The handle facilitates pushing and pulling by the user.

[0081] In some embodiments, a first heat exchanger, a second heat exchanger, and a compressor are disposed inside the machine body 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 through the compressor, and the refrigerant flows in the first heat exchanger and the second heat exchanger to perform heat conversion.

[0082] Furthermore, the first heat exchanger is close to the interior of the body 100, and the second heat exchanger is far away from the interior of the body 100. The refrigerant enters the second heat exchanger and is cooled. The cooled refrigerant enters the first heat exchanger, the first heat exchanger is cooled, and the interior of the body 100 is cooled by the first heat exchanger with a lower temperature.

[0083] 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 machine body 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.

[0084] In some embodiments, a first fan is provided at the first heat exchanger, and the first fan blows airflow toward the first heat exchanger. The airflow flows into the interior of the body 100 after being heated by the first heat exchanger, thereby improving the cooling effect on the interior of the body 100.

[0085] 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 inside of the machine body 100.

[0086] Through the description of multiple embodiments of the refrigerator of the utility model, it can be seen that the refrigerator of the utility model has at least one or more of the following advantages:

[0087] 1. The opening of the machine body 100 is closed by the first door panel 200, the second door panel 300 and the third door panel 400. The contact area between the first door panel 200 and the second door panel 300 and the slideway is small, which reduces friction and is convenient for users to open. When the user opens or closes the door structure, the user can push forward or pull backward the first door panel 200 at the front side of the machine body 100, which is convenient for the user to exert force, thereby facilitating the user to open or close the opening of the machine body 100 and improving the user experience;

[0088] 2. The friction between the first door panel 200 and the first slideway 600 and the second slideway 700 is reduced by the first roller 900 and the second roller 110, so as to further facilitate the user to open the first door panel 200.

[0089] 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.

[0090] 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.
