[0050] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0051] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0052] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0053] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0054] In the related art, refrigerators are usually provided with drawers for storing items. Existing drawers usually have two structures. One is a drawer that is separately arranged in the box body. After the user opens the refrigerator door, it is necessary to pull out each layer of drawers to take out and put food, which is inconvenient to operate; the other is a drawer installed on the door body. When the user opens the refrigerator door, the drawer can be pulled out together with the door body to directly take out the food in the drawer. However, when the drawer installed on the door body has multiple layers, the drawer located at the bottom is blocked by the drawer above, which makes it very inconvenient for the user to take and put items in the drawer below, reducing the convenience of using the refrigerator.

[0055] To this end, the present invention provides a refrigerator that is convenient for users to take out and put in items.

[0056] Reference Figures 1 to 5 An embodiment of the present invention provides a refrigerator, comprising a housing 100 and a drawer assembly 300. The housing 100 is generally rectangular, but may also be of other shapes. The housing 100 has an inner cavity for storing items. When items are placed in the inner cavity, they can be cooled and refrigerated through heat exchange.

[0057] Reference Figure 2 The drawer assembly 300 includes a door 200, which is slidably connected to the cabinet 100 along a first direction. Specifically, the door 200 can slide toward or away from the cabinet 100 along the first direction. When the door 200 slides toward the cabinet 100 along the first direction to a set position, the door 200 can cover the cabinet 100 to close the inner cavity and prevent the cold air from leaking out. When the door 200 slides away from the cabinet 100 along the first direction to a set position, the door 200 detaches from the cabinet 100 to open the inner cavity, making it easier for users to take items in and out.

[0058] Reference Figure 3 The drawer assembly 300 further includes a plurality of drawers for storing items, each of which is mounted on the side of the door body 200 facing the inner cavity. Specifically, the drawer assembly 300 includes a first drawer 310, a second drawer 320, and a third drawer 330, arranged from top to bottom. The first drawer 310 is located above the second drawer 320, and the third drawer 330 is located below the second drawer 320. Of course, the number of second drawers 320 can be multiple, for example, two, three, or more second drawers 320 can be provided.

[0059] Reference Figure 3 and Figure 5 At least one of the first drawer 310 and the second drawer 320 can be slidably connected to the door body 200 in the first direction or the second direction, and the third drawer 330 can be slidably connected to the door body 200 in the second direction, thereby being staggered with the second drawer 320 above it. The first direction and the second direction are perpendicular to each other. Specifically, the first direction can be the front-to-back direction, and the second direction can be the left-to-right direction.

[0060] When the user pulls the door body 200 along the first direction to open the inner cavity of the box body 100, the door body 200 drives the multiple drawer assemblies installed thereon to move out of the inner cavity and out of the outside of the box body 100, thereby making it convenient for the user to take out and put in the items in the first drawer 310; when the user needs to take out and put in the items in the second drawer 320, the user can push the first drawer 310 to slide along the first direction or the second direction to expose the second drawer 320 below, or slide the second drawer 320 along the second direction to be staggered with the first drawer 310 above, so that the user can conveniently take out and put in the items in the second drawer 320; when the user needs to take out and put in the items in the third drawer 330, the user can push the third drawer 330 to slide along the second direction, or slide the second drawer 320 along the first direction or the second direction, so that the third drawer 330 can be staggered with the second drawer 320 above, so that the user can conveniently take out and put in the items in the third drawer 330. By the above arrangement, when the drawer assembly 300 is provided with multiple layers of drawers, the user can still conveniently take out and put in items on the drawer assembly 300, thereby improving the convenience of using the refrigerator.

[0061] Reference Figure 2 In order to enable the door body 200 to be slidably connected to the box body 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 connected in parallel to the side of the door panel 210 facing the box body 100. The box body 100 is provided with first box guide rails 110 arranged along a first direction. There are also two first box guide rails 110. The two first box guide rails 110 are respectively installed on the cavity walls on both sides of the inner cavity. Each first mounting seat 220 is slidably installed on the corresponding first box guide rail 110, so that the door body 200 can be smoothly slidably connected to the box body 100 along the first direction. In addition, because the two first mounting seats 220 are arranged in parallel and spaced apart, when the first drawer 310 slides along the first direction, the user can take items into and out of the second drawer 320 through the space between the two first mounting seats 220, which is more convenient to operate.

[0062] Reference Figure 6 and Figure 7Specifically, in order to improve the smoothness of the sliding installation of the first mounting seat 220 on the first box guide rail 110, in some embodiments of the present invention, the first mounting seat 220 includes a first mounting plate 221 and a first door guide rail, the first door guide rail is installed on the outer wall of the first mounting plate 221, and the first box guide rail 110 is slidably connected to the first door guide rail. Specifically, structural parts such as ball bearings can be provided between the first box guide rail 110 and the first door guide rail, so that the first door guide rail can slide on the first box guide rail 110. Specifically, the outer walls of the first mounting plates 221 of the two first mounting seats 220 are both installed with first door guide rails, and the two first door guide rails are respectively slidably connected to the corresponding first box guide rail 110, thereby making the sliding connection between the door 200 and the box 100 more reliable.

[0063] Reference Figure 7 It is understood that in order to increase the maximum sliding stroke of the door body 200 in the first direction, in some embodiments of the present invention, the first door body guide rail includes a first door inner guide rail 226 and a first door outer guide rail 227. The first door inner guide rail 226 is fixed to the first mounting plate 221, and the first door outer guide rail 227 is slidably connected to the outer wall of the first door inner guide rail 226. The first box guide rail 110 is slidably connected to the outer wall of the first door outer guide rail 227. As a result, when the door body 200 slides in the first direction, the first door outer guide rail 227 can slide a certain distance relative to the first box guide rail 110. At the same time, the first door inner guide rail 226 can also slide a certain distance relative to the first door outer guide rail 227, thereby allowing the door body 200 to slide a greater distance relative to the box body 100 to meet usage requirements. Of course, a ball bearing can be provided between the first door inner guide rail 226 and the first door outer guide rail 227 to reduce the friction between the first door inner guide rail 226 and the first door outer guide rail 227.

[0064] It should be noted that, since the first door inner guide rail 226 is mounted on the outer wall of the first mounting plate 221, when the door body 200 moves outward to open the inner cavity, the first door inner guide rail 226 will be exposed to the outside of the box body 100 and easily touched by foreign objects, or cause dust and other debris to easily enter the first door inner guide rail 226 and affect the normal operation of the first door body guide rail. For this reason, refer to Figure 7In some embodiments of the present invention, the first mounting seat 220 also includes a baffle plate 222, which is connected to the first mounting plate 221 and is surrounded by the first mounting plate 221 to form an accommodating cavity. The first door inner guide rail 226 is located in the accommodating cavity, so that when the door body 200 moves outward and opens the inner cavity, the first door inner guide rail 226 and part of the first door outer guide rail 227 are still blocked by the baffle plate 222, so that external dust and other debris cannot easily enter the first door inner guide rail 226, which is beneficial to improving the smooth operation of the first door body guide rail. Moreover, since the first door inner guide rail 226 can be hidden, it is beneficial to improve the overall aesthetics of the door body 200. At the same time, when the door body 200 slides toward the box body 100 and closes the inner cavity, part of the first door outer guide rail 227 and the first box body guide rail 110 can also be accommodated in the accommodating cavity. Therefore, the baffle 222 can also protect this part of the first door outer guide rail 227 and the first box body guide rail 110, which is beneficial to improve the reliability of the door body 200 sliding relative to the box body 100.

[0065] Reference Figure 7 It should be noted that, in order to be able to install the first box guide rail 110 on the cavity wall of the inner cavity, in some embodiments of the present invention, the first box guide rail 110 is also connected to a reinforcing iron 111, one end of the reinforcing iron 111 is connected to the first box guide rail 110, and the other end is connected to the cavity wall of the inner cavity, so that the first box guide rail 110 is fixedly installed on the cavity wall of the inner cavity. However, when the door body 200 slides toward the box body 100, the shielding plate 222 will follow the first mounting plate 221 to move toward the inner cavity, so that part of the first box guide rail 110 is accommodated in the accommodating cavity. At this time, there is a gap between the shielding plate 222 and the cavity wall of the inner cavity, and one end of the reinforcing iron 111 needs to extend out of the accommodating cavity to connect to the cavity wall of the inner cavity. Therefore, in order to avoid this part of the reinforcing iron 111, the accommodating cavity is provided with an opening 229, and the reinforcing iron 111 can extend out of the opening 229 to connect to the cavity wall of the inner 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 and positioned around the outside of the first mounting plate 221, leaving a gap with the lower end of the first mounting plate 221. This gap constitutes the opening 229 of the accommodating cavity. The opening 229 is elongated, so that within the sliding range of the door body 200, the door body 200 can avoid the reinforcing iron 111 through the opening 229, preventing the reinforcing iron 111 from affecting the sliding of the door body 200.

[0066] It is understandable that when the height of the upper end of the opening 229 is higher, it is easier for external dust to enter the accommodating cavity through the opening 229 and affect the normal operation of the first door guide rail. At the same time, it is also easier for users to see the first door guide rail located in the accommodating cavity through the opening 229, which reduces the overall aesthetics of the door body 200. For this reason, refer to Figure 7In some embodiments of the present invention, the height of the upper end of the opening 229 is less than or equal to the height of the lower edge of the first door outer guide rail 227, so that the height of the opening 229 is as small as possible, reducing the amount of dust entering the accommodating cavity through the opening 229, and at the same time enabling the baffle 222 to block the first door body guide rail as much as possible to prevent the user from being able to easily see the first door body guide rail from the opening 229, thereby further improving the aesthetics of the door body 200.

[0067] Reference Figure 6 and Figure 7 It should be noted that in order to enable the first drawer 310 to slide along the first direction on the door body 200 and make the overall structure of the door body 200 more compact, in some embodiments of the present invention, the first mounting seat 220 also includes a second mounting plate 223 and a first drawer guide rail 228, the second mounting plate 223 is connected to the lower end of the first mounting plate 221, the first drawer guide rail 228 is installed on the inner wall of the second mounting plate 223, and the first drawer 310 is slidably installed on the first drawer guide 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 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 installation space inside and outside the first mounting seat 220 can be fully utilized, making the overall structure of the door body 200 more compact.

[0068] It can be understood that in order to enable the first drawer 310 to slide more smoothly on the first drawer guide rail 228, in some embodiments of the present invention, first mounting portions corresponding to the inner walls of the second mounting plate 223 are provided on both sides of the first drawer 310, and the first mounting portions are installed with first guide rails, which are slidably connected to the first drawer guide rail 228, so that the first drawer 310 can slide smoothly.

[0069] Reference Figure 7 It should be noted that, in order to enable the first drawer 310 to slide a longer stroke, in some embodiments of the present invention, the first guide rail includes a first inner guide rail 311 and a first outer guide rail 312, the first inner guide rail 311 is fixed to the first mounting portion, the first outer guide rail 312 is slidably sleeved on the outer wall of the first inner guide rail 311, and the first drawer guide rail 228 is slidably sleeved on the outer wall of the first outer guide rail 312. When the first drawer 310 slides toward the box body 100 along the first direction, the first inner guide rail 311 can slide a certain distance relative to the first outer guide rail 312, and at the same time, the first outer guide rail 312 can also slide a certain distance relative to the first drawer guide rail 228, so that the first drawer 310 can obtain a larger sliding stroke to meet the user's usage needs.

[0070] It can be understood that in order to reduce the friction between the first inner guide rail 311 and the first outer guide rail 312, in some embodiments of the present invention, the drawer assembly 300 also includes a first ball member, which is arranged between the first inner guide rail 311 and the first outer guide rail 312. The first ball member can roll between the first inner guide rail 311 and the first outer guide rail 312, thereby helping to reduce the friction between the first inner guide rail 311 and the first outer guide rail 312 and improve the smoothness of sliding.

[0071] Similarly, in some embodiments of the present invention, the drawer assembly 300 also includes a second ball bearing member, which is arranged between the first outer guide rail 312 and the first drawer guide rail 228. The second ball bearing member can roll between the first outer guide rail 312 and the first drawer guide rail 228, thereby reducing the friction between the first outer guide rail 312 and the first drawer guide rail 228 and improving the smoothness of sliding.

[0072] Reference Figure 7 It can be understood that since the second mounting plate 223 needs to withstand the sliding of the first drawer 310 thereon, in order to improve the bearing capacity of the second mounting plate 223, in some embodiments of the present invention, the first mounting seat 220 also includes a support plate 225 and a base plate 224. The base plate 224 is connected to the lower end of the first mounting plate 221, and the two ends of the support plate 225 are respectively connected to the base plate 224 and the second mounting plate 223. The support plate 225 can support the second mounting plate 223, thereby greatly improving the bearing capacity of the second mounting plate 223 and preventing the second mounting plate 223 from breaking easily.

[0073] It can be understood that in order to further improve the bearing capacity of the second mounting plate 223, in some embodiments of the present invention, multiple support plates 225 are provided, and the multiple support plates 225 are arranged at intervals, so that the second mounting plate 223 has more supporting force points, which is conducive to further improving the maximum bearing capacity of the second mounting plate 223.

[0074] It should be noted that, in order to facilitate the installation and connection between the second mounting plate 223 and the first door guide rail, in some embodiments of the present invention, the first mounting plate 221 includes a first side plate and a first bottom plate, the first bottom plate being connected to the lower end of the first side plate, the first door guide rail being mounted to the first side plate by bolts or other means, and the second mounting plate 223 being connected to the lower end of the first bottom plate, which makes the installation and connection more convenient. Of course, the second mounting plate 223 and the first mounting plate 221 can also be manufactured in an integrated manner.

[0075] Reference Figure 7It should be noted that, since the first drawer guide rail 228 is installed on the inner side of the first mounting seat 220, in order to reduce the space occupied by the first drawer guide rail 228, in some embodiments of the present invention, the second mounting plate 223 is connected to the middle part of the lower end of the first bottom plate, so that the first bottom plate and the second mounting plate 223 are surrounded to form a sinking position, and the first drawer guide rail 228 is located in the sinking position, thereby preventing the first drawer guide rail 228 from protruding out of the first bottom plate and occupying the space of the first drawer 310, which is conducive to increasing the storage space of the first drawer 310.

[0076] It should be noted that, since multiple drawers are mounted on the door body 200, the overall load-bearing capacity of the door body 200 is relatively large, and the vertical dimension of the door body 200 is relatively large. In the above embodiment, although the upper end of the door body 200 is slidably connected to the first box guide rail 110 of the box body 100 through two first mounting seats 220, the lower end of the door body 200 still does not receive sliding support, which may cause the door body 200 to slide less smoothly. For this reason, refer to Figure 4 In some embodiments of the present invention, the door body 200 further includes a second mounting seat 230, which is connected to the door panel 210 and is located below the first mounting seat 220. The box body 100 is provided with a second box guide rail 120 arranged along the first direction. The second mounting seat 230 is slidably mounted on the second box guide rail 120, so that the lower end of the door body 200 can be slidably connected to the box body 100. Therefore, the overall force of the door body 200 is more balanced, which is conducive to improving the smoothness of the sliding of the door body 200. Of course, it should be noted that since the third drawer 330 is a bottom drawer and there is no need to consider the drawers below, the second mounting seat 230 can adopt a plate-shaped structure, and two second box guide rails 120 can be provided. The two second box guide rails 120 are installed parallel to the bottom wall of the inner cavity. The second mounting seat 230 is slidably connected to the two second box guide rails 120, so that the force is more stable.

[0077] Reference Figure 8 It can be understood that in order to enable the third drawer 330 to slide smoothly along the second direction and be connected to the door body 200, in some embodiments of the present invention, the upper end of the second mounting seat 230 is provided with a third drawer guide rail 231 arranged along the second direction, and the third drawer 330 is slidably mounted on the third drawer guide rail 231, so that the third drawer 330 can slide along the second direction to avoid the second drawer 320 above, thereby making it convenient for users to take and place items in the third drawer 330.

[0078] Of course, it should be noted that there are two third drawer guide rails 231, and the two third drawer guide rails 231 are arranged in parallel and spaced apart. The third drawer 330 is slidably connected to the two third drawer guide rails 231, so that the sliding connection between the third drawer 330 and the door body 200 is more balanced in force, and the sliding is more stable and smooth.

[0079] Reference Figure 8 It can be understood that in order to enable the third drawer 330 to be smoothly slidably installed on the third drawer guide rail 231, in some embodiments of the present invention, a third guide rail is installed at the bottom of the third drawer 330, and the third guide rail is slidably connected to the third drawer guide rail 231, thereby making the sliding of the third drawer 330 smoother.

[0080] Reference Figure 12 It should be noted that, in order to increase the sliding stroke of the third drawer 330 along the second direction, the third guide rail includes a third inner guide rail 333 and a third outer guide rail 334. The third outer guide rail 334 is slidably connected to the third drawer guide rail 231. The third inner guide rail 333 is fixed to the bottom of the third drawer 330 and is slidably connected to the third outer guide rail 334. When the third drawer 330 slides along the second direction, the third inner guide rail 333 can slide a certain distance relative to the third outer guide rail 334. At the same time, the third outer guide rail 334 can slide a certain distance relative to the third drawer guide rail 231, so that the third drawer 330 can slide a larger distance to meet the user's usage needs.

[0081] Reference Figure 8 It will be appreciated that, to facilitate access to and placement of items, in some embodiments of the present invention, the third drawer 330 includes a drawer body 331 and a drawer guide plate 332. The drawer body 331 is snap-connected to the drawer guide plate 332, and the third inner guide rail 333 is fixed to the bottom of the drawer guide plate 332. When the user needs to remove the drawer body 331 from the drawer guide plate 332, they only need to slightly lift the drawer body 331 upwards to separate the drawer body 331 and the drawer guide plate 332, thereby facilitating access to and placement of items within the drawer body 331.

[0082] Reference Figures 11 to 13 It is understood that in some embodiments of the present invention, the second mounting base 230 is provided with a slide 232, and the third drawer guide rail 231 is mounted in the slide 232. The second mounting base 230 is also equipped with a baffle 233 that is rotatably sealed at the end of the slide 232. In normal operation, when the third drawer 330 is in its original position, the baffle 233 is sealed at the end of the slide 232, thereby preventing dust and other debris from entering the slide 232 and affecting the sliding of the third drawer 330. At the same time, it can block the third guide rail and the third drawer guide rail 231, which is conducive to improving the simplicity and aesthetics of the drawer assembly 300. When the third drawer 330 slides in the second direction, the third guide rail can push the baffle 233 away and slide out of the slide 232, so that the third drawer 330 can be staggered with the second drawer 320 above it, so as to facilitate the access to and placement of items in the third drawer 330.

[0083] Reference Figure 12 and Figure 14 It is understood that in some embodiments of the present invention, the drawer assembly 300 further includes an elastic member having a fixed end 2341 and a movable end 2342. The fixed end 2341 is connected to the second mounting base 230, and the movable end 2342 is connected to the baffle 233. The elastic member can drive the baffle 233 to seal the end of the slide groove 232. In normal operation, the elastic member has a certain elastic force, thereby sealing the baffle 233 to the end of the slide groove 232 through the movable end 2342. When the third drawer 330 is pushed in the second direction, the third drawer 330 drives the third guide rail to move outward, and the third guide rail pushes the baffle 233 to overcome the elastic force of the elastic member, so that the baffle 233 flips in the direction away from the slide groove 232 to expose the end of the slide groove 232. Therefore, the third guide rail can slide out of the outside of the slide groove 232 through the end of the slide groove 232, so that the third drawer 330 can move outward to a suitable distance to avoid the second drawer 320, thereby making it convenient for users to take and put items in the third drawer 330.

[0084] Reference Figure 14 and Figure 15 It is understood that in some embodiments of the present invention, the elastic member is a torsion spring 234, and the torsion spring 234 has good elasticity. The torsion spring 234 is provided with two fixed ends 2341 and a movable end 2342. The two fixed ends 2341 are respectively located at the two ends of the torsion spring 234 along the axial direction. The fixed ends 2341 extend outward relative to the torsion spring 234 body. The movable end 2342 is located in the middle of the torsion spring 234 and extends outward relative to the torsion spring 234 body. Through the above arrangement, when the baffle 233 flips, the baffle 233 transmits the force to the torsion spring 234 through the movable end 2342. The torsion spring 234 then transmits the force to the second mounting seat 230 through the movable ends 2342 at both ends, making the force and deformation of the torsion spring 234 more balanced, thereby facilitating the improvement of the service life of the torsion spring 234.

[0085] It is understood that in order to facilitate the installation of the fixed end 2341 of the torsion spring 234, in some embodiments of the present invention, the second mounting base 230 is provided with a socket, and the fixed end 2341 is inserted into the socket. During installation, the fixed end 2341 of the torsion spring 234 is inserted toward the socket, which makes installation quick and convenient. The socket is roughly rectangular, and its length direction is basically consistent with the axial direction of the torsion spring 234. The width of the socket is slightly larger than the outer diameter of the fixed end 2341, which makes it easier to insert the fixed end 2341 into the socket and prevents the fixed end 2341 from shaking too much in the socket. At the same time, the length of the socket is relatively long relative to the width, which facilitates the movement of the fixed end 2341 along the length direction of the socket, thereby allowing the torsion spring 234 to have a certain amount of movement space along its axial direction, preventing the torsion spring 234 from easily getting stuck and causing the baffle 233 to be unable to flip.

[0086] Reference Figure 14 It will be appreciated that, to facilitate installation of the movable end 2342 of the torsion spring 234, in some embodiments of the present invention, a limiting groove 2331 is provided on the side of the baffle 233 facing the chute 232, and the movable end 2342 is inserted into the limiting groove 2331. Specifically, the inner wall of the baffle 233 is provided with a bent portion that bends toward the torsion spring 234 to form the limiting groove 2331. During installation, the movable end 2342 is inserted into the limiting groove 2331. When the baffle 233 is pushed by the third guide rail and flips to open the end of the chute 232, the baffle 233 pushes the movable end 2342 against the inner wall of the limiting groove 2331, causing the torsion spring 234 to twist under the force. When the third guide rail slides into the chute 232, the torsion spring 234 pushes against the inner wall of the limiting groove 2331 via the movable end 2342, thereby forcing the baffle 233 to flip and close the end of the chute 232. Specifically, along the axial direction of the torsion spring 234 , the width of the limiting groove 2331 is greater than the width of the end of the movable end 2342 , thereby preventing the movable end 2342 from easily detaching from the limiting groove 2331 from both sides of the limiting groove 2331 , causing the torsion spring 234 to be unable to push the baffle 233 .

[0087] Reference Figure 14 It is understandable that when the axial dimension of the torsion spring 234 is relatively large, the torsion spring 234 is easily twisted when deformed by force and shakes too much relative to the baffle 233, causing the fixed end 2341 to easily detach from the socket, or the movable end 2342 to detach from the limiting groove 2331, causing the torsion spring 234 to be unable to provide elastic support for the baffle 233. To this end, in some embodiments of the present invention, the baffle 233 is also equipped with a fixed shaft 235, and the torsion spring 234 is wound around the outside of the fixed shaft 235, so that the fixed shaft 235 can support the torsion spring 234, and prevent the torsion spring 234 from shaking too much when deformed, so that the various deformations of the torsion spring 234 are more balanced, which is conducive to increasing the pressure that the torsion spring 234 can withstand, so that the user can quickly push the third drawer 330. When the third drawer 330 drives the third guide rail to quickly push open the baffle 233, the torsion spring 234 will not loosen from the baffle 233 under the action of a large thrust, thereby improving the reliability of the torsion spring 234.

[0088] Reference Figure 14It is understood that in order to mount the fixed shaft 235 on the baffle 233, in some embodiments of the present invention, limiting holes are provided on both sides of the baffle 233, and the two ends of the fixed shaft 235 are inserted into the limiting holes. During installation, the ends of the fixed shaft 235 are inserted into the limiting holes, so that the fixed shaft 235 can be mounted on the inner wall of the baffle. The fixed shaft 235 can be a round shaft, which can rotate when installed in the limiting holes, making the installation of the round shaft more convenient and allowing the torsion spring 234 to have a certain amount of rotation space when it is sleeved on the outside of the round shaft. Of course, the fixed shaft 235 can also be a square shaft or a shaft of other shapes.

[0089] Reference Figure 12 It is understood that in order to prevent the baffle 233 from rotating after it flips to the set position, in some embodiments of the present invention, the drawer assembly 300 further includes a stopper 236. The stopper 236 is mounted on the second mounting base 230. The stopper 236 has a protrusion 2361, and the baffle 233 is provided with a notch 2332 that cooperates with the protrusion 2361. When the baffle 233 flips to the stopper 236, the protrusion 2361 of the stopper 236 fits into the notch 2332 of the baffle 233, thereby preventing the baffle 233 from further flipping and allowing the baffle 233 to remain in the set position, thereby closing the end of the chute 232.

[0090] Reference Figure 14 It is understood that in order to make the baffle 233 flip more smoothly, in some embodiments of the present invention, the baffle 233 is provided with a rotating shaft 2333, and the limit block 236 is provided with a rotating hole, and the rotating shaft 2333 is rotatably mounted in the rotating hole. Specifically, two rotating shafts 2333 are provided, and the two rotating shafts 2333 are respectively located on both sides of the lower end of the baffle 233, and two rotating holes are also provided accordingly. The rotating shafts 2333 are respectively inserted into the corresponding rotating holes and can rotate therein. When the third guide rail pushes the baffle 233, the baffle 233 can rotate in the rotating hole via the rotating shaft 2333, thereby flipping and opening the end of the slide slot 232, and the flipping of the baffle 233 is smoother and more stable.

[0091] It should be noted that, after the third drawer 330 slides in the second direction, if the door body 200 is moved in the first direction toward the box body 100, the third drawer 330 will collide with the box body 100, causing damage to the third drawer 330 or the box body 100. Figure 8The refrigerator is also provided with a drawer stop structure 500, which includes a stopper 510, a matching member 520 and a trigger member 530. The stopper 510 is fixed relative to the box body 100, the trigger member 530 is fixed relative to the third drawer 330, and the matching member 520 is swingably mounted on the second mounting seat 230. The matching member 520 is provided with a first matching portion 521, a supporting portion 523 and a second matching portion 522. The first matching portion 521 and the second matching portion 522 are located at both ends of the supporting portion 523, so that the first matching portion 521 and the second matching portion 522 can swing in opposite directions around the supporting portion 523. Figure 9 In the normal state, the drawer stop structure 500 is in its original position. At this time, the third drawer 330 is in its original position on the second mounting seat 230. At this time, the trigger member 530 abuts against the first matching portion 521, and the second matching portion 522 swings upward at a certain angle around the support portion 523, so that the lower edge height of the second matching portion 522 is higher than the upper edge height of the stop member 510. At this time, the stop member 510 will not prevent the second matching portion 522 from moving toward the box body 100 along the first direction. Therefore, the door body 200 can move toward the box body 100 along the first direction. Figure 10 When the third drawer 330 moves along the second direction, the trigger member 530 disengages from the first matching portion 521, and the second matching portion 522 swings downward under its own gravity or the action of auxiliary structural parts such as elastic parts, so that the lower edge height of the second matching portion 522 is lower than the upper edge height of the stop member 510. At this time, the drawer stop structure 500 is in the blocking position, and the stop member 510 can block the second matching portion 522 from moving toward the box body 100 along the first direction. Therefore, when the door body 200 moves toward the box body 100 along the first direction, the stop member 510 abuts against the second limit portion, thereby blocking the door body 200 from continuing to move toward the box body 100, thereby preventing the third drawer 330 from colliding with the box body 100. Only when the third drawer 330 is moved back to its original position can the door body 200 be pushed back toward the box body 100.

[0092] Reference Figure 1 It should be noted that, in order to improve the refrigeration efficiency of the refrigerator, in some embodiments of the present invention, the refrigerator further includes an air duct plate 400, which is mounted on the door body 200 and provided with an air outlet facing the drawer assembly 300. Specifically, a fan is installed in the air duct plate 400, which may be an axial flow fan. The air discharged by the fan is blown toward the drawer assembly 300 through the air outlet, thereby accelerating the heat exchange efficiency between the cold air and the items in the drawer assembly 300, thereby improving the refrigeration efficiency of the refrigerator. Moreover, since the air duct plate 400 is mounted on the door body 200, the air duct plate 400 can move with the door body 200, so that the air duct plate 400 can maintain air outlet and heat exchange for the items in the multiple drawers mounted on the door body 200, which is conducive to improving the refrigeration effect.

[0093] It is understood that in order to further improve the heat exchange efficiency of items stored in the drawer assembly 300, in some embodiments of the present invention, the air outlet includes a first air outlet 410 and a second air outlet 420, the first air outlet 410 is located between the first drawer 310 and the second drawer 320, and the second air outlet 420 is located between the second drawer 320 and the third drawer 330. As a result, when the first air outlet 410 discharges air, it can accelerate the flow of cold air at the bottom of the first drawer 310 and above the second drawer 320, thereby achieving rapid cooling of the first drawer 310 and the second drawer 320, thereby improving the cooling efficiency. Similarly, when the second air outlet 420 discharges air, it can accelerate the flow of cold air at the bottom of the second drawer 320 and above the third drawer 330, thereby achieving rapid cooling of the second drawer 320 and the third drawer 330, thereby improving the cooling efficiency.

[0094] It can be understood that in order to firmly install the air duct plate 400 on the door body 200, in some embodiments of the present invention, one end of the air duct plate 400 is connected to the first mounting seat 220, and the other end of the air duct plate 400 is connected to the second mounting seat 230, so that the upper and lower ends of the air duct plate 400 can be installed and fixed, preventing the air duct plate 400 from loosening and falling when the air duct plate 400 moves with the door body 200.

[0095] It should be noted that in order to further improve the refrigeration efficiency of the refrigerator, in some embodiments of the present invention, a metal heat-conducting plate is provided on the cavity wall of the inner cavity away from the door body 200, and an evaporator is installed on the back of the metal heat-conducting plate. The evaporator transfers the cold energy to the inner cavity through the metal heat-conducting plate. Since the metal heat-conducting plate has a higher thermal conductivity, the above arrangement allows the cold energy of the evaporator to be quickly transferred to the air in the inner cavity through the metal heat-conducting plate, thereby causing the air temperature in the inner cavity to drop rapidly, which is beneficial to improving the refrigeration efficiency of the refrigerator. Of course, it should be noted that the metal heat-conducting plate can extend to the top wall and the side walls on both sides of the inner cavity, so that the cold energy of the evaporator can be quickly distributed to various parts of the inner cavity through the metal heat-conducting plate, which is beneficial to further improve the refrigeration effect of the refrigerator.

[0096] It is understood that in some embodiments of the present invention, the evaporator is a plate-and-tube evaporator, which can be better attached to the back of the metal heat-conducting plate, thereby being able to quickly transfer the cold energy through the metal heat-conducting plate to the air in the inner cavity. Specifically, the air duct plate 400 is provided with an air inlet, the evaporator is attached to one side of the metal heat-conducting plate, the air inlet is aligned with the other side of the metal heat-conducting plate, and the fan is provided between the air inlet and the air outlet. Therefore, the fan can transfer the cold energy transferred from the evaporator to the inner cavity through the metal heat-conducting plate, quickly draw it into the air inlet of the air duct plate 400, and then blow it toward the drawer assembly 300 through the air outlet, so that the items in the drawer assembly 300 can be quickly cooled, which is beneficial to the refrigeration effect of the items in the refrigerator.

[0097] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the spirit of the present invention.
