[0064] The freezer compartment of an existing refrigerator generally uses drawers to store food, and the refrigerator includes multiple layers of drawers stacked in layers. The storage space of each layer of drawers is independent of each other and can be used to place food, which can achieve classified storage and improve space utilization. However, the multi-layer drawer structure results in a fixed volume of each layer of drawers and storage is limited, which cannot meet the needs of placing larger food.

[0065] Based on this, in order to solve the above problems, the present application designs a refrigerator, in which the first drawer has a first use position and a second use position. In the first use position, the first storage cavity and the second storage cavity are independent of each other, which can realize classified storage and improve space utilization; in the second use position, the first storage cavity and the second storage cavity are connected up and down to form a storage cavity with a larger storage volume, which can store food with higher height and larger size; then the user can adjust the use position of the first drawer accordingly according to the needs of storing food to change the size of the multi-layer drawer volume, so that the use of the refrigerator is more user-friendly and the storage function is richer.

[0066] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The embodiment of the present application provides a refrigerator, including a box 200 and a drawer assembly 100 movably arranged in the box 200; the drawer assembly 100 includes a first drawer 10 and a second drawer 20; the first drawer 10 has a first accommodating cavity 11 and an opening 12 located at the front end of the first accommodating cavity 11, and the first drawer 10 includes a support plate 13 forming the bottom wall of the first accommodating cavity 11; the second drawer 20 has a second accommodating cavity 21; the first drawer 10 has a first use position and a second use position; in the first use position, the first drawer 10 is stacked and limitedly connected above the second drawer 20, the first accommodating cavity 11 and the second accommodating cavity 21 are separated by the support plate 13, and the second drawer 20 can drive the first drawer 10 to move forward and backward in the box 200; in the second use position, the first drawer 10 is stacked above the second drawer 20, the first accommodating cavity 11 and the second accommodating cavity 21 are connected, and the first drawer 10 and the second drawer 20 are released from the limited connection.

[0067] The drawer assembly 100 of the embodiment of the present application is a multi-layer drawer structure, including but not limited to a first drawer 10 and a second drawer 20, the first drawer 10 is used to be stacked above the second drawer 20, and the two are detachably connected; drawers can also be further stacked at the bottom of the second drawer 20.

[0068] refer to Figure 1 , Figure 4 , the first drawer 10 is in the first use position, the first drawer 10 is stacked on the second drawer 20, and the support plate 13 is located at the bottom of the first drawer 10. In this first use position, the support plate 13 isolates the first accommodating cavity 11 of the first drawer 10 from the second accommodating cavity 21 of the second drawer 20, that is, the first accommodating cavity 11 and the second accommodating cavity 21 are independent of each other, and both can store food separately, realize classified storage, and improve space utilization.

[0069] It can be understood that the first drawer 10 is limitedly connected to the second drawer 20, and the second drawer 20 can drive the first drawer 10 to move forward and backward in the box 200, thereby realizing the one-time dragging of the multi-layer drawers, so that the user can quickly lock the position of the required ingredients in the multi-layer drawers, thereby enhancing the convenience of the user in using the multi-layer drawers.

[0070] refer to Figure 2 , Figure 3 and Figure 5 , when the first drawer 10 is in the second use position, the first drawer 10 is still stacked on the second drawer 20, and the support plate 13 is located on the top of the first drawer 10; that is, the second drawer 20 in the second use position is horizontally flipped 180° relative to the second drawer 20 in the first use position. In this second use position, the first storage cavity 11 and the second storage cavity 21 are connected up and down to form a storage cavity with a larger storage volume, which can store food with a higher height and larger size; for example, the height of the first storage cavity 11 is h1, and the height of the second storage cavity 21 is h2. At this time, the height of the larger storage cavity formed between the first drawer 10 and the second drawer 20 is h1+h2.

[0071] In addition, in the second usage position, the first drawer 10 and the second drawer 20 are released from the limiting connection, and the first drawer 10 and the second drawer 20 have no linkage relationship. The first drawer 10 moves independently in the box 200, and then when the second drawer 20 is dragged out of the box 200, the first drawer 10 will stay in the box 200.

[0072] It can be understood that in the second usage position, the opening 12 at the front end of the first drawer 10 is formed between the support plate 13 and the second drawer 20. The opening 12 can avoid the higher food stored in the second drawer 20, so that the first drawer 10 will not occupy the upper space of the second accommodating cavity 21; then, when the second drawer 20 is pulled relative to the first drawer 10, the food in the first drawer 10 and the second drawer 20 will not contact and interfere with each other.

[0073] In the refrigerator of the present application, the first drawer 10 has a first use position and a second use position. In the first use position, the first accommodating cavity 11 and the second accommodating cavity 21 are independent of each other, and classified storage can be achieved to improve space utilization; in the second use position, the first accommodating cavity 11 and the second accommodating cavity 21 are connected up and down to form a accommodating cavity with a larger storage volume, which can store food with a higher height and a larger size; then the user can adjust the use position of the first drawer 10 accordingly according to the demand for storing food to change the size of the multi-layer drawer volume, so that the use of the refrigerator is more user-friendly and the storage function of the drawer assembly 100 is richer.

[0075] In some embodiments, the two sides of the first drawer 10 are the two sides in the left-right direction, and the two sides of the second drawer 20 are the two sides in the left-right direction. The left and right sides of the second drawer 20 are symmetrically provided with sliding support parts 22, and the left and right sides of the first drawer 10 are symmetrically provided with the first sliding part 14 and the second sliding part 15; then, when the first drawer 10 is in the first use position and the second use position, the stacked structure of the first drawer 10 and the second drawer 20 is stable.

[0076] refer to Figure 4 When the first drawer 10 is in the first use position, although the first sliding portion 14 slides in the sliding support portion 22, the first sliding portion 14 is used to be limitedly connected with the second drawer 20, effectively limiting the sliding of the first drawer 10 relative to the second drawer 20, so that the first drawer 10 and the second drawer 20 form a linkage, and the multi-layer drawers can be dragged out at one time.

[0077] Exemplarily, the first sliding portion 14 and the second drawer 20 may be connected by a limiting connection method such as snap connection, buckle connection, or bonding, so as to form a linkage between the first drawer 10 and the second drawer 20 in the front-to-back direction.

[0078] refer to Figure 5 When the first drawer 10 is in the second use position, the second sliding portion 15 slides in the sliding support portion 22, and the second drawer 20 can move in the front and rear direction relative to the first drawer 10. When the second drawer 20 is dragged out of the box 200, the first drawer 10 will stay in the box 200.

[0079] Exemplarily, the first sliding part 14 and the second sliding part 15 and the sliding support part 22 can adopt any one of the sliding cooperation methods of the slider and the slide groove, the sliding cooperation method of the roller and the slide rail, and the sliding cooperation method of the slide seat and the slide rail, without specific limitation here, so as to ensure that the first drawer 10 and the second drawer 20 can slide relative to each other.

[0080] refer to Figures 6 to 9 In some embodiments, the sliding support portion 22 includes a first slide groove 221 arranged at the top of the inner wall of the second drawer 20, and the first slide groove 221 extends along the front-to-back direction; the first sliding portion 14 includes at least two first sliders 141 arranged on the outer wall of the first drawer 10 at intervals along the front-to-back direction; the second sliding portion 15 includes at least two second sliders 151 arranged on the outer wall of the first drawer 10 at intervals along the front-to-back direction.

[0081] refer to Figure 6 and Figure 7 It can be understood that the first slide groove 221 is directly opened at the top of the inner side wall of the second drawer 20, the first slider 141 is arranged at one end of the outer side wall of the first drawer 10 close to the support plate 13 in the vertical direction, and the second slider 151 is arranged at one end of the outer side wall of the first drawer 10 away from the support plate 13 in the vertical direction. The first drawer 10 is stacked on the second drawer 20 in the first use position, and the first slider 141 is matched in the first slide groove 221; the first drawer 10 is stacked on the second drawer 20 in the second use position, and the second slider 151 is matched in the first slide groove 221; the sliding matching structure is simple and reliable, and the structure is easy to process.

[0082] On the outer wall on one side of the first drawer 10, there are at least two first sliders 141 spaced front to back and at least two second sliders 151 spaced front to back. Specifically, on the outer wall on one side of the first drawer 10, the number of the first sliders 141 can be 2, 3 or 4, and the number of the second sliders 151 can be 2, 3 or 4; thus, the sliding support structure of the first drawer 10 and the second drawer 20 is stable and has good structural reliability.

[0083] Specifically, the shape of the first slider 141 can be a strip, a protrusion, a hemispherical shape, an elliptical shape, etc.; the shape of the second slider 151 can be a strip, a protrusion, a hemispherical shape, an elliptical shape, etc.

[0084] refer to Figures 6 to 11In some embodiments, the drawer assembly 100 also includes a first limiting structure 40, the first limiting structure 40 includes a first limiting groove 41 provided on one of the first slider 141 and the first slide groove 221, and a first limiting block 42 correspondingly provided on the other of the first slider 141 and the first slide groove 221; when the first drawer 10 is in the first use position, the first slider 141 is engaged in the first slide groove 221, and the first limiting block 42 is upwardly clamped in the first limiting groove 41.

[0085] Specifically, when the first drawer 10 is in the first use position, the first limit block 42 is engaged with the first limit groove 41 to realize the linkage between the first drawer 10 and the second drawer 20. When the second drawer 20 is pulled forward from the box 200, the second drawer 20 can drive the first drawer 10 to be pulled forward out of the box 200, that is, the second drawer 20 can drive the first drawer 10 to move forward. It should be noted that when the second drawer 20 is pushed backward into the box 200, the second drawer 20 can also drive the first drawer 10 to be pushed into the box 200, that is, the second drawer 20 can drive the first drawer 10 to move backward.

[0086] Understandably, reference Figure 1 and Fig.10 When the first drawer 10 and the second drawer 20 are both pulled out of the box 200, the food in the first accommodating cavity 11 can be directly taken out and placed. If the second accommodating cavity 21 needs to be opened, it is only necessary to lift the front end of the first drawer 10 so that the first limiting groove 41 can be disengaged from the first limiting block 42. At this time, the first drawer 10 is disconnected from the second drawer 20, and the two do not form a linkage relationship, so that the first drawer 10 can move back and forth alone in the box 200, that is, the first drawer 10 can be pushed backward into the box 200, and then the second accommodating cavity 21 of the second drawer 20 is opened.

[0087] refer to Figures 6 to 10 In some embodiments, a first limiting groove 41 is provided on the first sliding block 141 located at the front end of the first drawer 10 , and a first limiting block 42 is correspondingly provided on the first sliding groove 221 .

[0088] Specifically, refer to Fig.10 The number of the first limit block 42 is one, and the first limit block 42 is arranged at a position close to the front end of the first slide groove 221. Then, when the first drawer 10 is in the first use position, by lifting the front end of the first drawer 10, the first limit groove 41 on the first slider 141 at the corresponding position is conveniently disengaged from the first limit block 42; and after the first limit groove 41 on the first slider 141 is disengaged from the first limit block 42, the first drawer 10 can be pushed backward relative to the second drawer 20 into the box liner 200 alone, and the first limit block 42 will not interfere with the first slider 141, and will not affect the movement of the first drawer 10.

[0089] refer to Figure 5 , Fig.11 When the first drawer 10 is in the second use position, the second slider 151 is engaged in the first slide groove 221 , and the second slider 151 located at the front end of the first drawer 10 is located behind the first limit block 42 .

[0090] It can be understood that when the first drawer 10 is in the second usage position, the first limit block 42 and the second slider 151 are offset front to back, the second drawer 20 is disconnected from the first drawer 10, and the second drawer 20 can be pulled out of the box 200 alone; and the second slider 151 located at the front end of the first drawer 10 is located behind the first limit block 42, and then during the process of pulling out the second drawer 20 alone, the first limit block 42 is never in contact with any second slider 151, and the first drawer 10 can stay stably in the box 200.

[0091] In some other embodiments, the first limiting block 42 is disposed on the first sliding block 141 located at the front end of the first drawer 10 , and the first limiting block 42 is correspondingly recessed in the first sliding groove 221 .

[0092] Exemplarily, the end of the first limit block 42 is arc-shaped. When the first limit block 42 on the first slider 141 is disengaged from the first limit groove 41 in the first slide groove 221, the first limit block 42 can slide and abut against the first slide groove 221, and then can independently push the first drawer 10 to retreat back into the box 200 relative to the second drawer 20.

[0093] refer to Figures 10 to 12 In some embodiments, the refrigerator further includes a guide structure 60 disposed on the inner wall of the box, the guide structure 60 including a first slide 61 extending in the front-to-back direction; when the drawer 10 is in the first use position, the second slider 151 is located above the first slide 61, and there is a gap between the second slider 151 and the first slide 61; when the first drawer 10 is in the second use position, the first slider 141 abuts against the first slide 61, and there is a gap between the second slider 151 and the bottom wall of the first slide groove 221.

[0094] It can be understood that when the first drawer 10 is in the first usage position, the support plate 13 is located at the bottom of the first drawer 10, the first slider 141 located at the bottom of the first drawer 10 forms a sliding abutment with the first slide groove 221, and the first limit block 42 on the first slide groove 221 is upwardly engaged in the first limit groove 41 of the first slider 141; at this time, the second slider 151 located at the top of the first drawer 10 is located above the first slide 61 and there is a gap between the second slider 151 and the first slide 61, and then the second slider 151 does not contact the first slide 61. In this first usage position, the first slide 61 does not interfere with the movement of the first drawer 10, and the first drawer 10 and the second drawer 20 are stably engaged, and dragging the second drawer 20 can effectively drive the first drawer 10 to move forward and backward.

[0095] When the first drawer 10 is in the second use position, the support plate 13 is located at the top of the first drawer 10, the first slider 141 located at the top of the first drawer 10 forms a sliding contact with the first slide 61, and there is a gap between the second slider 151 located at the bottom and the bottom wall of the first slide groove 221; at this time, the second slider 151 located at the bottom does not contact the first slide groove 221, that is, the first drawer 10 and the second drawer 20 do not form a linkage relationship; in the second use position, the first slide 61 supports the first drawer 10, and then when the second drawer 20 is dragged forward, the first drawer 10 will stay in the box 200. When the second drawer 20 is dragged forward, the first drawer 10 can be directly dragged to move in the front-back direction, and the second slider 151 will slide forward and backward along the first slide 61.

[0096] refer to Fig.12 In some embodiments, a slope 611 is provided at the front end of the first slide 61 , and the front end height of the slope 611 is lower than the rear end height of the slope 611 .

[0097] It can be understood that the front end of the first slide 61 is provided with a slope 611, and the distance between the slope 611 and the top wall of the box 200 in the vertical direction is greater than the distance between the first slide 61 and the top wall of the box 200 in the vertical direction. Then, when the first drawer 10 is taken out from the first use position and put back into the box 200 to adjust to the second use position, the first slider 141 is located at the top of the first drawer 10, and the first slider 141 will first enter the first slide 61 along the slope 611, and then enter the box 200 backward along the first slide 61, so that the first drawer 10 can be taken and placed more conveniently and simply.

[0098] refer to Figures 10 to 12In some embodiments, a stopper 612 protruding upward is provided at the rear end of the first slide 61. In the first use position, the stopper 612 is used to limit the second slider 151 at the rear end of the first drawer 10 to limit the first drawer 10 from moving backward; in the second use position, the stopper 612 is used to limit the first slider 141 at the rear end of the first drawer 10 to limit the first drawer 10 from moving backward.

[0099] refer to Figures 7 to 9 In some embodiments, the support plate 13 is formed with a slope section 1301, and when the first drawer 10 is in the first use position, the front end of the support plate 13 is higher than the rear end of the support plate 13.

[0100] It can be understood that the support plate 13 has an inclined slope section 1301, so that when the first drawer 10 is in the first use position, the front end of the support plate 13 is higher than the rear end of the support plate 13, which can prevent the food placed in the first drawer 10 from rolling down the support plate 13 during the drawing process. The slope section 1301 can be an arc-shaped inclined structure; or, the slope section 1301 can also be a straight-line inclined structure.

[0101] refer to Fig. 9 In some embodiments, the slope section 1301 is provided at the front end of the support plate 13, that is, the portion of the support plate 13 other than the slope section 1301 is horizontal, which is conducive to supporting food. Specifically, in this embodiment, the length of the slope section 1301 along the front-to-back direction is L1, the length of the support plate 13 along the front-to-back direction is L2, and the slope section 1301 is formed with an inclined surface that is at an angle to the horizontal plane; if L1≤2 / 3L2, the angle range between the inclined surface and the horizontal plane is 0-90°; if L2≥L1≥2 / 3L2, the angle range between the inclined surface and the horizontal plane is 0-60°; then the inclination angle of the slope section 1301 is set to a more appropriate range according to its length, so that the slope of the slope section 1301 is moderate and does not affect the support plate 13 to support food.

[0102] In some other embodiments, the slope section 1301 spans across the front and rear ends of the support plate 13 along the front-to-rear direction, that is, the support plate 13 is tilted as a whole, and the angle between the support plate 13 and the horizontal plane ranges from 0° to 45°.

[0103] refer to Figure 4 , Figures 7 to 9 In some embodiments, the first drawer 10 further includes a surrounding plate 1302 disposed at the front end of the support plate 13 to form a barrier for the portion of the first accommodating cavity 11 .

[0104] It can be understood that the front end of the support plate 13 is further provided with a panel 1302, referring to Figure 1 When the first drawer 10 is in the first use position, the enclosure 1302 protrudes upward from the support plate 13 , which can effectively prevent food from falling from the support plate 13 .

[0105] It can be understood that the vertical distance between the top of the enclosing plate 1302 and the supporting plate 13 is less than the height h1 of the first accommodating cavity 11, so that the first drawer 10 can form an opening 12 at the front end. Specifically, the vertical distance between the top of the enclosing plate 1302 and the supporting plate 13 is less than 3 / 4h1, so that the opening 12 has a certain height. Figure 2 When the second drawer 20 is in the second use position, the opening 12 can leave a large avoidance space between the support plate 13 and the second drawer 20.

[0106] refer to Figure 7 , Fig.11 In some embodiments, a cushion block 1411 is provided on the first slider 141 located at the front end of the first drawer 10; when the first drawer 10 is in the second use position, the cushion block 1411 protrudes downward relative to the first slider 141 and abuts against the first slide 61 to make the support plate 13 higher at the front and lower at the back.

[0107] It can be understood that when the first drawer 10 is in the second usage position, the pallet 13 is located on the top of the first drawer 10, and the pad 1411 can raise the front end of the pallet 13 so that the pallet 13 is higher in the front and lower in the back, which is beneficial to increase the distance between the front end of the second drawer 20 and the front end of the pallet 13. During the process of dragging out the second drawer 20, the structural interference between the food in the second drawer 20 and the pallet 13 is small.

[0108] Moreover, when the first drawer 10 is in the first use position, the cushion block 1411 protrudes upward relative to the first sliding block 141 , which does not affect the matching relationship between the first sliding block 141 and the first sliding groove 221 , and the structural design is ingenious.

[0109] refer to Figure 8 In some embodiments, a sliding protrusion 142 is provided on the first sliding block 141 , and the sliding protrusion 142 is used to abut against the bottom wall of the first sliding groove 221 .

[0110] It can be understood that when the first drawer 10 is in the first use position, the second drawer 20 will drive the first drawer 10 to be pulled forward out of the box 200; and after the first drawer 10 and the second drawer 20 are pulled out of the box 200 together, if the second accommodating cavity 21 needs to be opened, the first limiting groove 41 on the first slider 141 needs to be disengaged from the first limiting block 42, so that the first drawer 10 can be pushed backward into the box 200. Then, a sliding protrusion 142 is provided on the first slider 141, and the sliding protrusion 142 abuts against the bottom wall of the first slide groove 221, which can reduce the contact area between the first slider 141 and the bottom wall of the first slide groove 221, reduce the sliding friction, and can easily push the first drawer 10 back into the box 200.

[0111] refer to Figures 1 to 3 , Fig.13 , Fig.14 In some embodiments, the drawer assembly 100 also includes a third drawer 30, and the second drawer 20 is stacked on the third drawer 30; the drawer assembly 100 also includes a second limiting structure 50 arranged between the third drawer 30 and the second drawer 20, and the third drawer 30 is connected to or disengaged from the second drawer 20 through the second limiting structure 50.

[0112] It can be understood that when the third drawer 30 is connected to the second drawer 20 through the second limiting structure 50, the third drawer 30 can drive the second drawer 20 to move forward and backward in the box 200; and when the second limiting structure 50 between the third drawer 30 and the second drawer 20 is disengaged, the second drawer 20 can move forward and backward alone in the box 200.

[0113] refer to Fig.13 In some embodiments, second slide grooves 31 are provided at the tops of both sides of the third drawer 30, and the second slide grooves 31 extend in the front-to-back direction; third sliders 23 are provided at the bottoms of the outer walls on both sides of the second drawer 20; the second limiting structure 50 includes a second limiting block 52 provided at the front of the second slide groove 31 and a second limiting groove 51 corresponding to the bottom of the third slider 23, and the second drawer 20 is stacked on the third drawer 30 so that the second limiting block 52 is upwardly inserted into the second limiting groove 51.

[0114] Specifically, refer to Fig.13 A second slide groove 31 is provided at the top of both sides of the third drawer 30, and the second slide groove 31 extends in the front-to-back direction. The outer walls on both sides of the second drawer 20 are provided with a third slider 23 at the bottom. The second drawer 20 is stacked on the third drawer 30, and the third slider 23 can slide back and forth along the second slide groove 31.

[0115] The second drawer 20 is stacked on the third drawer 30 so that the second limit block 52 is inserted into the second limit groove 51 upward; therefore, when the third drawer 30 is pulled forward out of the box 200, the third drawer 30 can also drive the second drawer 20 to be pulled out of the box 200. When the third drawer 30 and the second drawer 20 are both pulled out of the box 200, it is only necessary to lift the front end of the second drawer 20 so that the second limit groove 51 on the third slider 23 is disengaged from the second limit block 52. At this time, the third drawer 30 is disconnected from the second drawer 20, and the two do not form a linkage relationship. The third slider 23 can slide forward and backward along the second slide groove 31, and thus the second drawer 20 can move forward and backward in the box 200 alone, that is, the second drawer 20 can be pushed backward into the box 200 to take and put food in the third drawer 30.

[0116] It can be understood that the drawer assembly 100 of the present application can further stack drawers below the third drawer 30 without being limited to three layers of drawers.
