[0030] An embodiment of the present invention provides a refrigerator, as Figure 1 shown, including: a compartment, a drawer 2, and a slide rail 3. The drawer 2 is movably disposed in the compartment along a first direction through the slide rail 3. The slide rail 3 includes a fixed rail 31 and a moving rail 32. The fixed rail 31 is fixedly disposed on the inner wall of the compartment. The fixed rail 31 is disposed along the first direction. The moving rail 32 is slidably disposed with the fixed rail 31. The moving rail 32 slides relative to the drawer 2, so that the drawer 2 can be in two states: being received in the compartment or being pulled out of the compartment. The drawer 2 includes a main body 21 and brackets 22 on both sides of the main body 21. The brackets 22 are in contact with the top of the slide rail 3 in the vertical direction. The brackets 22 are slidably disposed with the compartment through the slide rail 3. The slide rail 3 supports the brackets 22 to bear the weight of the drawer 2. The brackets 22 have a plurality of second ribs 222 spaced along the first direction.

[0031] Wherein, the first direction is the front-back direction for entering or leaving the compartment. Specifically, the first direction is the front-back direction horizontally arranged perpendicular to the vertical direction. In other variant embodiments, the first direction can be any direction in the horizontal direction.

[0032] As described in the background, the contact positions between the drawer 2 and the slide rail 3 are a plurality of transverse ribs. That is, the plurality of transverse ribs are in contact with the top plane of the slide rail 3. The collision contact points between the drawer 2 and the slide rail 3 increase. The slide rail 3 contacts and rubs against the transverse ribs, resulting in an increase in friction and abnormal noise during the pushing and pulling of the drawer 2, affecting the user experience. In a refrigerator of the present application, the bracket 22 further includes a first rib 221. The first rib 221 intersects with the plurality of second ribs 222, and the first rib 221 is lower than the second ribs 222 in the vertical direction. The slide rail 3 contacts the first rib 221. The slide rail 3 abuts against the lower part of the first rib 221 in the vertical direction. The slide rail 3 supports the bracket 22, reducing the contact between the slide rail 3 and the plurality of second ribs 222, thereby reducing the generation of abnormal noise when pulling out the drawer 2.

[0033] When the drawer 2 moves in the first direction, the drawer 2 has a maximum stroke in the first direction relative to the moving rail 32. That is, when the drawer 2 is in the fully open state, the maximum distance that the drawer 2 can move relative to the moving rail 32 in the first direction. The drawer 2 has a first limit position and a second limit position relative to the moving rail 32. In this embodiment, the first limit position is when the drawer 2 is in the fully closed state, and the second limit position is the farthest position that the drawer 2 can reach relative to the compartment when the drawer 2 is in the fully open state. The maximum stroke of the drawer 2 relative to the moving rail 32 in the first direction is the distance between the first limit position and the second limit position.

[0034] The length that the first rib 221 continuously extends in the first direction is not less than the maximum stroke. In this embodiment, the length that the first rib 221 continuously extends in the first direction is the maximum stroke. When the drawer 2 and the moving rail 32 are at the first limit position or the second limit position, the first rib 221 abuts against the moving rail 32.

[0035] As Figure 2 shown, specifically, there are two brackets 22, and the two brackets 22 are respectively fixed on the opposite outer side walls of the main body 21, and the two brackets 22 are both arranged in the first direction. The main body 21 is internally provided with a receiving cavity and an opening communicating with the receiving cavity, and the opening is arranged vertically upward. The two brackets 22 are fixed on the two opposite outer side walls of the edge of the opening. When the drawer 2 slides into the compartment through the moving rail 32, the opening of the main body 21 is closed in the compartment. When the drawer 2 slides out of the compartment through the moving rail 32, the opening of the main body 21 is located outside the compartment for the user to take and place items.

[0036] As Figure 3 and 4 shown, specifically, a plurality of second ribs 222 are fixed on the side surface of the bracket 22 facing downward in the vertical direction. In this embodiment, the plurality of second ribs 222 are perpendicular to the first direction. That is, the plurality of second ribs 222 are arranged vertically, and the plurality of second ribs 222 are arranged at intervals in the first direction. Preferably, one end of the second rib 222 is fixedly connected to the bracket 22, and the other end is a free end. The free ends of the plurality of second ribs 222 are coplanar, and this plane is a horizontal plane. The plurality of second ribs evenly share the pressure of the bracket 22; more preferably, the first rib 221 protrudes downward in the vertical direction from the plane where the free ends of the second ribs 222 are located.

[0037] As Figure 5 and 6As shown, in this embodiment, both the first rib 221 and the second rib 222 are plate-like structures, and both the first rib 221 and the second rib 222 extend downward from the bottom of the bracket 22. The first rib 221 and the second rib 222 are arranged perpendicular to each other, that is, the first rib 221 is arranged along the first direction. Preferably, there is one first rib 221 and the first rib 221 is fixed at the middle position of the second rib 222, and the moving rail 32 contacts the narrow side of the first rib 221, thus replacing the situation where the moving rail 32 contacts the long sides of multiple second ribs 222. The contact area and contact points on the moving rail 32 are reduced, and the generation of abnormal noises is reduced. More preferably, the number of the first ribs 221 is two, and the two first ribs 221 are both arranged to cross the multiple second ribs 222, and the two first ribs 221 are both arranged along the first direction, that is, the two first ribs 221 are arranged parallel to each other, and the two first ribs 221 are both in contact with the moving rail 32, reducing the risk of the slide rail 3 shaking.

[0038] Among them, from the structure of the first rib 221, the narrow side of the first rib 221 can be known. The first rib 221 is a long strip plate-like structure, the first rib 221 has a thickness, and the thickness direction of the first rib 221 is the narrow side of the first rib 221. From the structure of the second rib 222, the long side of the second rib 222 can be known. The side of the second rib 222 perpendicular to the first direction is the long side.

[0039] Each bracket 22 is provided with a limiting portion 223. The limiting portion 223 is fixed at the edge of the bracket 22. Specifically, the limiting portion 223 is fixed at the edge of the bracket 22 facing away from the main body 21. The limiting portion 223 extends along the first direction and protrudes downward along the edge of the bracket 22. The first rib 221 and the second rib 222 are located between the limiting portion 223 and the main body 21. The limiting portion 223 is lower than the first rib 221 and the second rib 222 in the vertical direction, and the first rib 221 is lower than the second rib 222 in the vertical direction. The slide rail 3 is located between the limiting portion 223 and the main body 21, and the limiting portion 223 and the main body 21 can limit the sliding of the slide rail 3 at the bottom of the bracket 22, reducing the risk of the slide rail 3 detaching from the drawer 2.

[0040] In this embodiment, the bracket 22 includes multiple third ribs 224. The third ribs 224 are fixedly connected to the bracket 22 through the second ribs 222. Specifically, the third ribs 224 are fixed on the outer wall of the main body 21, and one end of the third ribs 224 is fixedly connected to the second ribs 222, and the second ribs 222 are fixedly connected to the third ribs 224. In other variant embodiments, one end of the third ribs 224 is fixed on the outer wall of the main body 21, and the third ribs 224 are fixed at the bottom of the bracket 22. The top of the second ribs 222 is fixed at the bottom of the bracket 22, and the second ribs 222 are fixedly connected to the main body 21, and the multiple third ribs 224 and the second ribs 222 are arranged alternately.

[0041] Preferably, a plurality of third ribs 224 are arranged in one-to-one correspondence with a plurality of second ribs 222. More preferably, the third ribs 224 and the second ribs 222 are arranged in an "L" shape to prevent the third ribs 224 from interfering with the movement of the slide rail 3 and to enhance the connection strength between the bracket 22 and the main body 21.

[0042] The main body 21 includes a fourth rib 226 and a rib plate 225. The rib plate 225 is fixed to the outer wall of the main body 21 through the fourth rib 226. The rib plate 225 is parallel to the vertical plane, and the third ribs 224 and the rib plate 225 are arranged at intervals in the first direction. In this embodiment, the end face of the rib plate 225 facing away from the main body 21 is coplanar with the end of the third rib 224 facing away from the main body 21. Both the third ribs 224 and the rib plate 225 can support the side of the slide rail 3. In other variant embodiments, the third ribs 224 protrude from the rib plate 225 such that the third ribs 224 are in contact with the slide rail 3, or the rib plate 225 protrudes from the third ribs 224 such that the rib plate 225 is in contact with the slide rail 3.

[0043] As Figure 7 and 8 As shown, there are two groups of slide rails 3, and the slide rails 3 and the brackets 22 are in one-to-one correspondence. The moving rail 32 and the fixed rail 31 are slidably arranged in the first direction. The moving rail 32 is in contact with the first rib 221, and the moving rail is slidably arranged with the bracket 22 through the first rib 221. A transmission assembly is provided between the fixed rail 31 and the moving rail 32. The transmission assembly includes a first transmission frame 33 and a second transmission frame 34. The first transmission frame 33 is fixed to the moving rail 32 in the first direction, and the second transmission frame 34 is fixed to the fixed rail 31 in the first direction. The first transmission frame 33 and the second transmission frame 34 are arranged in parallel. The first transmission frame 33 is internally provided with a first groove 331, and the second transmission frame 34 is internally provided with a second groove 341. The first transmission frame 33 and the second transmission frame 34 are distributed in the vertical direction, and there is a gap between the first transmission frame 33 and the second transmission frame 34. The openings of the first groove 331 and the second groove 341 are arranged opposite to each other.

[0044] The transmission assembly further includes a guide rail 37. The upper half of the guide rail 37 is slidably arranged in the first groove 331, and the lower half of the guide rail 37 is slidably arranged in the second groove 341. A carrier 36 and balls 35 are provided in the first groove 331. Specifically, the carrier 36 is provided with a plurality of holes for accommodating the balls 35. The balls 35 roll between the guide rail 37 and the first transmission frame 33. That is, the balls 35 are in contact with the inner wall of the first groove 331 and the upper half of the guide rail 37. The carrier 36 is sleeved outside the guide rail 37, and the balls 35 roll in the holes of the carrier 36 so that the balls 35 can maintain a distance from each other to avoid interference or collision between the balls 35.

[0045] In summary, an embodiment has the following beneficial effects: The main body 21 is supported on the slide rail 3 through the bracket 22, and the drawer 2 slides into or out of the compartment through the slide rail 3; the slide rail 3 contacts the first rib 221 in the first direction. On the one hand, the contact points between the slide rail 3 and the second rib 222 are reduced, thereby reducing the generation of abnormal noises between the second rib 222 and the bracket 22 of the slide rail 3. On the other hand, the frictional resistance between the slide rail 3 and the bracket 22 is reduced, thereby reducing the sliding resistance of the drawer 2 relative to the slide rail 3 and improving the user experience.
