In the related art, a refrigerator is generally provided with a drawer for storing articles, and the existing drawer is generally provided with two structures, wherein one structure is a drawer which is independently arranged in the refrigerator, and after a user opens a refrigerator door, the user also needs to draw out each layer of drawer to take and put foods, so that the operation is inconvenient; the other type is the drawer installed on the door body, when a user opens the refrigerator door, the drawer can be pulled out together with the door body, so that food in the drawer can be directly taken out, however, when the drawer installed on the door body is provided with multiple layers, the drawer positioned below is inconvenient for the user to take out the articles of the drawer below due to the shielding of the drawer above, and the convenience of the refrigerator is reduced.

Therefore, the invention provides the refrigerator which is convenient for users to take and put articles.

Referring to fig. 1 to 5, a refrigerator according to an embodiment of the present invention includes a cabinet 100 and a drawer assembly 300. The case 100 is substantially rectangular, but may be other shapes, and the case 100 has an inner cavity for storing articles, and the articles can be cooled and refrigerated by heat exchange when placed in the inner cavity.

Referring to fig. 2, the drawer assembly 300 includes a door body 200, and the door body 200 is slidably coupled to the cabinet 100 in a first direction, and in particular, the door body 200 can be slid toward or away from the cabinet 100 in the first direction. When the door body 200 slides towards the box body 100 along the first direction to a set position, the door body 200 can be covered on the box body 100 so as to close the inner cavity, and the cold is prevented from leaking; when the door 200 slides away from the case 100 in the first direction to the set position, the door 200 is separated from the case 100 to open the inner cavity, so that the user can take and put the articles conveniently.

Referring to fig. 3, the drawer assembly 300 further includes a plurality of drawers for storing articles, each of the plurality of drawers being installed at a side of the door body 200 facing the cavity. Specifically, the drawer assembly 300 includes a first drawer 310, a second drawer 320, and a third drawer 330 distributed from top to bottom, the first drawer 310 being located above the second drawer 320, and the third drawer 330 being located below the second drawer 320. Of course, the number of the second drawers 320 may be provided in plural, for example, the second drawers 320 may be provided in two or three or more.

Referring to fig. 3 and 5, at least one of the first drawer 310 and the second drawer 320 can be slidably coupled to the door body 200 in a first direction or a second direction, and the third drawer 330 can be slidably coupled to the door body 200 in the second direction so as to be staggered from the second drawer 320 above, and the first direction and the second direction are perpendicular. Specifically, the first direction may be a front-rear direction, and the second direction may be a left-right direction. Of course, the second drawer 320 may be fixed to the door body 200, or may be slidably connected to the door body 200 along the first direction or along the second direction.

When the user pulls the door body 200 in the first direction to open the inner cavity of the case 100, the door body 200 drives the plurality of drawer assemblies mounted thereon to move out of the inner cavity of the case 100, thereby facilitating the user to take and place the articles in the first drawer 310; when a user needs to take and put the articles in the second drawer 320, the first drawer 310 can be pushed to slide along the first direction or the second direction, so that the second drawer 320 below is exposed, or the second drawer 320 slides along the second direction to be staggered with the first drawer 310 above, so that the user can conveniently take and put the articles in the second drawer 320; when the user needs to take and put the articles in the third drawer 330, the third drawer 330 can be pushed to slide along the second direction, or the second drawer 320 can be slid along the first direction or the second direction, so that the third drawer 330 can be staggered with the second drawer 320 above, and the user can conveniently take and put the articles in the third drawer 330. Through the arrangement, when the drawer assembly 300 is provided with the multi-layer drawers, a user can still conveniently take and put the articles on the drawer assembly 300, and the convenience of the refrigerator is improved.

Referring to fig. 2, in order to enable the door body 200 to be slidably coupled to the case 100, in some embodiments of the present invention, the door body 200 includes a door panel 210 and two first mounting seats 220, the two first mounting seats 220 are coupled in parallel to a side of the door panel 210 facing the case 100, the case 100 is provided with first case guide rails 110 arranged along a first direction, the first case guide rails 110 are also provided with two, two first case guide rails 110 are respectively mounted to cavity walls at both sides of an inner cavity, and each first mounting seat 220 is slidably mounted to a corresponding first case guide rail 110, thereby enabling the door body 200 to be smoothly slidably coupled to the case 100 along the first direction. In addition, since the two first mounting seats 220 are arranged in parallel at intervals, when the first drawer 310 slides along the first direction, a user can take and place the second drawer 320 through the space between the two first mounting seats 220, and the operation is convenient.

Referring to fig. 6 and 7, specifically, in order to improve smoothness of sliding mounting of the first mount 220 to the first case rail 110, in some embodiments of the present invention, the first mount 220 includes a first mounting plate 221 and a first door rail mounted to an outer wall of the first mounting plate 221, and the first case rail 110 is slidably connected to the first door rail. Specifically, structural members such as balls may be disposed between the first case guide rail 110 and the first door guide rail, so that the first door guide rail can slide on the first case guide rail 110. Specifically, the first door body guide rails are mounted on the outer walls of the first mounting plates 221 of the two first mounting seats 220, and the two first door body guide rails are respectively and slidably connected with the corresponding first box body guide rails 110, so that the sliding connection between the door body 200 and the box body 100 is more reliable.

Referring to fig. 7, it can be appreciated that in order to enhance the maximum travel of the door 200 sliding in the first direction, in some embodiments of the present invention, the first door body rail includes a first door body rail 226 and a first door body rail 227, the first door body rail 226 is fixed to the first mounting plate 221, the first door body rail 227 is slidably coupled to the outer wall of the first door body rail 226, and the first box rail 110 is slidably coupled to the outer wall of the first door body rail 227, such that when the door 200 slides in the first direction, the first door body rail 227 can slide a certain distance with respect to the first box rail 110, while the first door body rail 226 can also slide a certain distance with respect to the first door body rail 227, thereby enabling the door body 200 to slide a greater distance with respect to the box 100 to meet the use requirements. Of course, a ball member may be provided between the first door inner rail 226 and the first door outer rail 227, so that friction between the first door inner rail 226 and the first door outer rail 227 may be reduced.

It should be noted that, because the first door inner rail 226 is mounted on the outer wall of the first mounting plate 221, when the door body 200 moves outwards to open the inner cavity, the first door inner rail 226 is exposed outside the box body 100 and is easily touched by an external object, or impurities such as dust easily enter the first door inner rail 226 to affect the normal operation of the first door inner rail, so, referring to fig. 7, in some embodiments of the present invention, the first mounting seat 220 further includes a shielding plate 222, the shielding plate 222 is connected to the first mounting plate 221 and forms a containing cavity with the first mounting plate 221, and the first door inner rail 226 is located in the containing cavity, so that when the door body 200 moves outwards to open the inner cavity, the first door inner rail 226 and a part of the first door outer rail 227 still obtain shielding of the shielding plate 222, so that impurities such as external dust can not easily enter the first door inner rail 226, thereby facilitating the improvement of the running stability of the first door inner rail, and facilitating the improvement of the overall attractiveness of the door body 200 due to the hiding of the first door inner rail 226. Meanwhile, when the door body 200 slides towards the box body 100 to close the inner cavity, part of the first door body external guide rail 227 and the first box body guide rail 110 can also be accommodated in the accommodating cavity, so that the shielding plate 222 can also protect the first door body external guide rail 227 and the first box body guide rail 110 of the part, and the sliding reliability of the door body 200 relative to the box body 100 is improved.

Referring to fig. 7, in order to enable the first case rail 110 to be mounted on the wall of the inner cavity, in some embodiments of the present invention, the first case rail 110 is further connected with a reinforcing iron 111, one end of the reinforcing iron 111 is connected to the first case rail 110, and the other end is connected to the wall of the inner cavity, so that the first case rail 110 is fixedly mounted on the wall of the inner cavity. However, when the door 200 slides toward the case 100, the shielding plate 222 moves toward the cavity along with the first mounting plate 221, so that a portion of the first case rail 110 is received in the receiving cavity, and a gap is formed between the shielding plate 222 and the cavity wall of the cavity, and one end of the reinforcing iron 111 needs to extend out of the receiving cavity to be connected to the cavity wall of the cavity, so that in order to avoid the portion of the reinforcing iron 111, the receiving cavity is provided with an opening 229, and the reinforcing iron 111 can extend out of the opening 229 to be connected to the cavity wall of the cavity. Specifically, one end of the shielding plate 222 is connected to the upper end of the first mounting plate 221, and the other end of the shielding plate 222 is bent to enclose the outer side of the first mounting plate 221 and leave a gap with the lower end of the first mounting plate 221, where the gap forms an opening 229 of the accommodating cavity. At this time, the opening 229 is long, so that the door body 200 can avoid the reinforcing iron 111 through the opening 229 in the sliding stroke of the door body 200, so as to prevent the reinforcing iron 111 from affecting the sliding of the door body 200.

It will be appreciated that when the height of the upper end of the opening 229 is higher, external dust is more likely to enter the accommodating cavity through the opening 229 to affect the normal operation of the first door body rail, and at the same time, a user is likely to see the first door body rail located in the accommodating cavity through the opening 229 to reduce the overall aesthetic degree of the door body 200. For this reason, referring to fig. 7, in some embodiments of the present invention, the height of the upper end of the opening 229 is equal to or less than the height of the lower edge of the first door body outer rail 227, so that the height of the opening 229 is as small as possible, the amount of dust entering the accommodating cavity through the opening 229 is reduced, and the shielding plate 222 can shield the first door body rail as much as possible, so as to prevent the user from easily seeing the first door body rail from the opening 229, thereby further improving the aesthetic appearance of the door body 200.

Referring to fig. 6 and 7, it should be noted that, in order to enable the first drawer 310 to slide on the door body 200 along the first direction, and simultaneously make the overall structure of the door body 200 more compact, in some embodiments of the present invention, the first mounting seat 220 further includes a second mounting plate 223 and a first drawer rail 228, the second mounting plate 223 is connected to the lower end of the first mounting plate 221, the first drawer rail 228 is mounted on the inner wall of the second mounting plate 223, and the first drawer 310 is slidably mounted on the first drawer rail 228, so that the door body 200 can be slidably connected to the box body 100 through the outer side of the first mounting seat 220, and meanwhile, the first drawer 310 can be slidably connected to the inner side of the first mounting seat 220 along the first direction, so that the mounting space in and outside of the first mounting seat 220 can be fully utilized, and the overall structure of the door body 200 is more compact.

It will be appreciated that, in order to enable the first drawer 310 to slide on the first drawer rail 228 more smoothly, in some embodiments of the present invention, both sides of the first drawer 310 are provided with first mounting portions corresponding to the inner walls of the second mounting plate 223, the first mounting portions are mounted with first rails slidably connected to the first drawer rail 228, so that the first drawer 310 can slide smoothly.

When the third drawer 330 is pushed along the second direction, the third drawer 330 drives the third guide rail to move outwards, the third guide rail pushes the baffle 233 to overcome the elastic force of the elastic member, so that the baffle 233 turns towards the direction away from the chute 232 to expose the port of the chute 232, and therefore the third guide rail can slide out of the outside of the chute 232 through the port of the chute 232, and the third drawer 330 can move outwards to a proper distance to avoid the second drawer 320, thereby facilitating the user to take and put the articles in the third drawer 330.

Referring to fig. 14 and 15, it can be appreciated that in some embodiments of the present invention, the elastic member is a torsion spring 234, and the torsion spring 234 has better elasticity. The torsion spring 234 is provided with two fixed ends 2341 and a movable end 2342, and two fixed ends 2341 are located the both ends of torsion spring 234 along the axial respectively, and fixed end 2341 outwards stretches out relative torsion spring 234 body, and movable end 2342 is located the middle part of torsion spring 234, and movable end 2342 outwards stretches out relative torsion spring 234 body. Through the arrangement, when the baffle 233 overturns, the baffle 233 transmits acting force to the torsion spring 234 through the movable end 2342, and the torsion spring 234 is transmitted to the second mounting seat 230 through the movable ends 2342 at the two ends, so that the stress deformation of the torsion spring 234 is more balanced, and the service life of the torsion spring 234 is prolonged.
