[0067] Figure 1 It is a structural diagram of a refrigerator box and a drawer in the related art. Figure 2 for Figure 1 A partial enlarged view of point A in the middle.

[0068] See also Figure 1 and Figure 2 As shown, the drawer 300 is located in the box 110, and the two side walls of the drawer 300 along the width direction are respectively provided with a first rail structure 310. The first rail structure 310 includes a first protrusion 312, and a plurality of first protrusions 312 are arranged at intervals along the depth direction of the drawer, and the extension direction of the first protrusion 312 is consistent with the width direction of the drawer 300. The first protrusion 312 is in line contact with the ribs 111 of the box 110. The width direction is the direction shown by the X axis in the figure, and the depth direction is the direction shown by the Y axis in the figure.

[0069] When the drawer 300 is loaded with a large amount of food, under the action of the gravity of the food, the contact mode between the first protrusion 312 and the ribs 111 changes to surface contact, and the friction force when the drawer 300 is pulled out increases. The ribs 111 are prone to wear after long-term use. At the same time, the increased friction force also affects the feel of the drawer 300 when it is pulled out. In addition, the ribs 111 formed by blistering are relatively low in strength and are prone to wear and tear.

[0070] In order to solve the above technical problems, the refrigerator provided by the present application is provided with a second guide rail structure on the inner wall of the box body, the first guide rail structure is slidably connected with the second guide rail structure, and the first guide rail structure and the second guide rail structure are in point contact, thereby solving the technical problem that the friction force is large when the drawer is pulled out after carrying a large amount of food. Since the first guide rail structure does not directly contact the gallbladder ribs, the gallbladder ribs are not easily worn and broken.

[0071] Moreover, compared with installing rollers on the drawer and adopting a rolling connection method, the present application adopts a sliding connection, which has less noise.

[0072] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application.

[0079] Figure 3 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the structure of the refrigerator box, drawer and second guide rail structure provided in the embodiment of the present application. Figure 5 for Figure 4 Exploded diagram.

[0080] See also Figures 3 to 5 As shown, this embodiment provides a refrigerator, including a box body 100 and a door body 200. It should be noted that the refrigerator in this application can be an air-cooled refrigerator or a direct-cooled refrigerator.

[0081] The box body 100 includes an outer shell, a box liner 110 and a press chamber.

[0082] Exemplarily, the outer shell is configured with a first accommodating cavity having a first access opening and a second access opening, and the first access opening and the second access opening are respectively arranged on opposite sides of the outer shell in the depth direction (the direction shown by the Y axis) of the box body 100. The first access opening can be arranged on the front side of the outer shell, and the second access opening can be arranged on the rear side of the outer shell. The press chamber is located in the outer shell, and the opening of the press chamber is opposite to the second access opening, and the compressor and the condenser can be placed in the press chamber through the second access opening and the opening.

[0083] The box 110 is located in the outer shell and forms at least one refrigeration compartment. The box 110 has a third access opening, which is opposite to the first access opening. Items can be placed in the refrigeration compartment through the third access opening and the first access opening.

[0084] In some embodiments, a foam layer is filled between the box 110, the outer shell and the press chamber, and the foam layer is used to insulate the refrigeration compartment, thereby ensuring the refrigeration effect in the refrigeration compartment.

[0085] In some embodiments, there may be at least one refrigeration compartment. When the number of refrigeration compartments is one, the refrigeration compartment may be any one of a refrigeration compartment, a freezer compartment, or a temperature-changing room. When the number of refrigeration compartments is two or more, the plurality of refrigeration compartments may include at least one or more of a refrigeration compartment, a freezer compartment, or a temperature-changing room.

[0086] In some embodiments, the door body 200 is an openable cover disposed on the front side of the box body 100 to close and open the refrigeration compartment and to take items into and out of the refrigeration compartment.

[0087] It should be noted that the number of door bodies 200 may be one, two or more.

[0088] Figure 6 This is a schematic diagram of the structure of a drawer in a refrigerator provided in an embodiment of the present application. Figure 7 This is a schematic diagram of the structure of the second guide rail structure in the refrigerator provided in an embodiment of the present application. Figure 8 The main view of 4 is Fig. 9 for Figure 8 The cross-sectional view along CC direction, Fig.10 for Fig. 9 A partial enlarged view of point B in the middle.

[0089] See also Figures 6 to 10 As shown, in some embodiments, the refrigerator includes: a drawer 300 and a second guide rail structure 400 , the drawer 300 is located in the box 110 , and the two side walls of the drawer 300 along the width direction of the box body 100 are respectively provided with a first guide rail structure 310 .

[0090] At least two second guide rail structures 400 are respectively arranged on the two inner side walls of the box 110 along the width direction of the box body 100, and the second guide rail structures 400 are arranged one-to-one corresponding to the first guide rail structures 310. The first guide rail structure 310 is slidably connected to the second guide rail structure 400, and the first guide rail structure 310 is in point contact with the second guide rail structure 400.

[0091] The width direction of the box body 100 is the direction indicated by the X axis in the figure, and the depth direction of the box body 100 is the direction indicated by the Y axis in the figure.

[0092] It is understandable that the refrigerator provided in the present application can solve the technical problem that the friction force of the drawer 300 is large when the drawer 300 is pulled out after carrying a large amount of food by arranging the second guide rail structure 400 on the inner wall of the box body 100, the first guide rail structure 310 is slidably connected with the second guide rail structure 400, and the first guide rail structure 310 is in point contact with the second guide rail structure 400. Since the first guide rail structure 310 does not directly contact the gallbladder rib 111, the gallbladder rib 111 is not easily worn.

[0093] Moreover, compared with installing rollers on the drawer 300 and adopting a rolling connection method, the present application adopts a sliding connection, which has less noise.

[0094] See also Figure 6 and Figure 7As shown, in some embodiments of the present application, the first guide rail structure 310 includes a first connecting portion 311 and a plurality of first protrusions 312, the plurality of first protrusions 312 are connected to the first connecting portion 311, the extension direction of the first connecting portion 311 is consistent with the depth direction of the box body 100, and the plurality of first protrusions 312 are spaced apart along the extension direction of the first connecting portion 311.

[0095] The second rail structure 400 includes a second connection portion 410 and at least one second protrusion 420 . The extension direction of the second protrusion 420 is consistent with the depth direction of the box body 100 . The first protrusion 312 is in point contact with the second protrusion 420 .

[0096] It can be understood that the point contact between the plurality of first protrusions 312 and the second protrusions 420 can increase the number of contact points and improve the smoothness of sliding.

[0097] In some embodiments, in order to improve the strength of the second rail structure 400 , the second protrusion 420 is a solid structure.

[0098] In some embodiments, in order to improve the reliability of the connection, the first connection portion 311 and the first protrusion portion 312 are integrally provided.

[0099] In some embodiments, in order to improve the reliability of the connection, the second connection portion 410 and the second protrusion portion 420 are integrally provided.

[0100] See also Figures 8 to 10 As shown, in some embodiments, along the cross section perpendicular to the width direction of the box body 100, the cross section of the first protrusion 312 is arc-shaped, and the cross section of the second protrusion 420 is arc-shaped. In this way, the first protrusion 312 and the second protrusion 420 are not easy to be worn.

[0101] It should be noted that the width direction of the box body 100 is consistent with the direction shown by the X-axis in the figure, and the cross section perpendicular to the width direction of the box body 100 is parallel to the cross section of the end face of the box body 100 along the width direction.

[0102] For example, the cross section of the first protrusion 312 may be semicircular, and the cross section of the second protrusion 420 may be semicircular.

[0103] In some embodiments, along the cross section perpendicular to the width direction of the box body 100, the cross section of the first protrusion 312 is triangular, and the cross section of the second protrusion 420 is triangular. In this way, the first protrusion 312 and the second protrusion 420 can easily ensure point contact.

[0104] In some embodiments, along a cross section perpendicular to the width direction of the box body 100 , one of the cross section of the first protrusion 312 and the cross section of the second protrusion 420 is arc-shaped, and the other is triangular.

[0105] See also Figure 7 As shown, in some embodiments of the present application, in order to improve the reliability of the second guide rail structure 400 , the number of the second protrusions 420 is at least two, and at least two second protrusions 420 are arranged side by side along the width direction of the box body 100 .

[0106] It can be understood that by providing at least two second protrusions 420 , the pressure of the drawer 300 can be shared, thereby increasing the service life of the second protrusions 420 and improving reliability.

[0107] In some embodiments, in order to save space, the number of the second protrusions 420 is at least two, and the at least two second protrusions 420 are arranged in parallel along the width direction of the box body 100 .

[0108] In some embodiments, in order to save space, two adjacent second protrusions 420 abut against each other.

[0109] In some embodiments, in order to improve the sliding stability of the drawer 300 , there is a distance between two adjacent second protrusions 420 .

[0110] Exemplarily, a second guide rail structure 400 includes two second protrusions 420 , and the two second protrusions 420 are arranged side by side along the width direction of the box body 100 . The two second protrusions 420 are parallel to each other and have a spacing therebetween.

[0111] See also Figure 6 As shown, in some embodiments of the present application, in order to improve the reliability of the first guide rail structure 310, the first guide rail structure 310 further includes a third connection portion 313, the third connection portion 313 is located between two adjacent first protrusions 312, and is connected to the two adjacent first protrusions 312, and there is a gap between the third connection portion 313 and the second guide rail structure 400. In this way, the third connection portion 313 can play an effect of strengthening the strength of the first guide rail structure 310.

[0112] In some embodiments, the first connection portion 311 , the first protruding portion 312 , and the third connection portion 313 are integrally provided.

[0113] In some embodiments, the third connection portion 313 is arc-shaped, with both ends of the arc respectively connected to two adjacent first protrusions 312, and the arc bends toward the side away from the second guide rail structure 400, that is, the center of the arc is located on the side facing the second guide structure, so that there is a gap between the third connection portion 313 and the second guide rail structure 400.

[0114] Fig.11 This is a schematic diagram of the structure of the refrigerator box provided in the embodiment of the present application. Fig.12 for Fig.11A partial enlarged view of point D in the middle. Fig.13 for Figure 4 A partial enlarged view of point E in the middle.

[0115] See also Figures 11 to 13 As shown, in some embodiments of the present application, in order to facilitate the installation and positioning of the second guide rail structure 400, the two inner side walls of the box 110 along the width direction of the box body 100 are provided with a rib 111, and the extension direction of the rib 111 is consistent with the depth direction of the box body 100. The second connecting portion 410 includes a first connecting section and a second connecting section connected to each other, the first connecting section abuts against the top of the rib 111, and the second connecting section is connected to the side wall of the box 110. Among them, the second protrusion 420 is provided on the top of the first connecting portion 311.

[0116] It is understandable that during the installation of the second guide rail structure 400 , the ribs 111 can play a supporting and positioning role.

[0117] In this embodiment, the second connecting portion 410 includes a first connecting section 411 and a second connecting section 412 that are connected to each other. The first connecting section 411 abuts against the top of the rib 111, and the second connecting section 412 is connected to the side wall of the box 110. In this way, there is no need to set a connecting structure on the first connecting section 411, and the flatness of the first connecting section 411 is easy to ensure. It is not easy to be deformed by force due to the connection with the box 110, which is beneficial to ensure the smooth movement of the drawer 300.

[0118] In some embodiments, the first connecting section 411 is integrally provided with the second connecting section 412 and the second protrusion 420 .

[0119] In some embodiments, the first connecting segment 411 is in the shape of a plate, the second connecting segment 412 is in the shape of a plate, and an extension plane of the first connecting segment 411 and an extension plane of the second connecting segment 412 have an included angle.

[0120] Specifically, an extension plane of the first connecting section 411 is perpendicular to an extension plane of the second connecting section 412 .

[0121] In some embodiments of the present application, in order to facilitate connection, a first clamping structure 413 is provided on the side of the second connecting section 412 away from the drawer 300, and a second clamping structure 112 is provided on the side wall of the box 110, and the second connecting section 412 is clamped with the box 110 through the first clamping structure 413 and the second clamping structure 112. In this way, the connection and disassembly of the second guide rail structure 400 and the box 110 are facilitated.

[0122] It is understandable that the first clamping structure 413 is provided on the side of the second connecting section 412 facing away from the drawer 300 , and the side of the second connecting section 412 facing the drawer 300 can be a plane, so that the second connecting section 412 can guide the movement of the drawer 300 .

[0123] In some embodiments, the number of the first clamping structures 413 may be at least two, and the at least two first clamping structures 413 are spaced apart along the depth direction of the box body 100. The number of the second clamping structures 112 may be at least two, and the at least two second clamping structures 112 are spaced apart along the depth direction of the box body 100. The at least two first clamping structures 413 and the at least two second clamping structures 112 are clamped one-to-one.

[0124] In some embodiments of the present application, the first clamping structure 413 includes a first clamping buckle, the second clamping structure 112 includes an opening 1121 and a second clamping buckle 1122, the second clamping buckle 1122 is located on the outer wall of the box 110, and the first clamping buckle is clamped with the second clamping buckle 1122 through the opening 1121. In this way, the reliability of the connection is higher.

[0125] During installation, place the second guide rail structure 400 on the top of the rib 111, and then push the second guide rail structure 400 along the depth direction of the box body 100 toward the inside of the box 110. The first buckle passes through the opening 1121 and is located outside the box 110. Continue to push the second guide rail structure 400 until the first buckle is engaged with the second buckle 1122, thereby completing the installation of the second guide rail structure 400.

[0126] Then, the first guide rail structure 310 of the drawer 300 is placed on the top of the second guide rail structure 400 and moved toward the inside of the box 110 along the depth direction of the box body 100, thereby completing the installation of the drawer 300.
