Description

Technical Field

[0001] This application relates to the field of low-temperature storage technology, such as a refrigerator. Background Technology

[0002] Based on their cooling method, refrigerators are divided into air-cooled refrigerators and direct-cooling refrigerators. For direct-cooling refrigerators, the efficiency of heat transfer between the cooling components and the object being frozen determines the refrigerator's cooling efficiency.

[0003] To improve the heat transfer efficiency between the refrigeration components and the frozen food, a refrigerator with a quick-freezing plate is disclosed in related technologies. The refrigerator includes a cabinet, a door, a refrigeration compartment formed by the cabinet and door, an evaporator that provides cooling capacity to the refrigeration compartment, and a quick-freezing plate located within the refrigeration compartment. The quick-freezing plate is thermally connected to the evaporator. Through this thermal connection, the quick-freezing plate and evaporator can rapidly exchange heat with each other, resulting in a small temperature difference. Furthermore, the heat from the food on the quick-freezing plate is quickly transferred to and exchanged with the evaporator, achieving a continuous quick-freezing effect.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The frozen items are quick-frozen on the quick-freezing plate. If the refrigeration compartment is deep, the frozen items are not easy to take out or put in, making the refrigerator inconvenient to use.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a refrigerator to address the problem of making the refrigerator easier to use while ensuring its cooling effect.

[0009] In some embodiments, the refrigerator includes a cabinet, a refrigeration module, a sliding rail, a drawer, a sliding part, and a pressing assembly. The cabinet has an accommodating space with an open front side. The refrigeration module is used to reduce the temperature of the bottom plate of the accommodating space. The sliding rail is disposed on the side wall of the accommodating space, and the second section of the sliding rail is inclined downwards. The drawer is removably disposed in the accommodating space. The sliding part extends outwards from the side wall of the drawer and cooperates with the sliding rail. When the sliding part slides from front to back to the second section of the sliding rail, the refrigerator drawer moves downwards to press against the bottom plate of the accommodating space. The pressing assembly is used to press the front end of the drawer downwards.

[0010] In some embodiments, the pressing assembly includes a rotating shaft, a locking member, and a locking pin, wherein the rotating shaft extends inward from the side wall of the accommodating space; the locking member is rotatably connected to the rotating shaft, a first end of the locking member having a snap-fit ​​groove, and a second end having a rotating handle; the locking pin extends outward from the side wall of the drawer, and when the sliding part slides to the second section of the sliding track, the locking pin engages with the snap-fit ​​groove and performs an arc-shaped movement under the constraint of the locking member, and the arc-shaped movement of the locking pin causes the front end of the drawer to move downward.

[0011] In some embodiments, the locking member is rotatable between a first angle and a second angle. When the locking member rotates from the first angle to the second angle, the front end of the drawer moves downward, and when the locking member rotates from the second angle to the first angle, the front end of the drawer is lifted upward. The locking member is provided with a locking pin, which, when extended, fixes the locking member at the second angle to lock the drawer.

[0012] In some embodiments, the sliding track includes a first groove and a second groove, wherein,

[0013] A first sliding groove is formed on the side wall of the accommodating space, with the first section being straight and the second section sloping downwards; a second sliding groove is formed on the side wall of the accommodating space, with the first section being straight and the second section sloping downwards; the sliding part includes a first sliding post and a second sliding post, wherein the first sliding post cooperates with the first sliding groove; and the second sliding post cooperates with the second sliding groove.

[0014] In some embodiments, the depth of the first groove is greater than the depth of the second groove, the length of the first sliding post is greater than the length of the second sliding post, the first segment of the second groove coincides with the first groove, and the second segment of the second groove forms a step with the first groove.

[0015] In some embodiments, the refrigerator further includes a spring top ball, which is telescopically disposed at the end of the second sliding post. When the second sliding post is located in the first section of the second slide groove, the spring top ball elastically presses against the bottom of the first slide groove, and when the second sliding post is located in the second section of the second slide groove, the spring top ball elastically presses against the step.

[0016] In some embodiments, the slope of the second section of the first slide is less than the slope of the second section of the second slide, and when the drawer is pushed back, the front end of the drawer flips downward at a preset angle.

[0017] In some embodiments, the lowest position of the second slide is lower than the lowest position of the first slide.

[0018] In some embodiments, there are two sliding rails, which are respectively disposed on two opposite side walls of the accommodating space. There are also two sliding parts, which are respectively disposed on two side panels of the drawer. Each of the two sliding parts corresponds to one of the two sliding rails.

[0019] In some embodiments, the refrigerator further includes a defrosting device for heating the base plate of the accommodating space.

[0020] The refrigerator provided in this embodiment can achieve the following technical effects:

[0021] 1. It is equipped with drawers, making it convenient for users to take out and put away frozen items from the refrigerator;

[0022] 2. The drawer does not come into contact with the bottom of the storage space during the sliding process, which can avoid scratching the bottom of the drawer or the bottom of the storage space.

[0023] 3. The second section of the sliding track is inclined downwards, so that when the drawer is pushed back, the bottom plate of the drawer is close to the bottom plate of the storage space. This can improve the heat exchange efficiency between the refrigeration module and the storage space and prevent frost from forming between the bottom plate of the drawer and the storage space.

[0024] 4. The front end of the drawer is equipped with a pressing component, which can cooperate with the sliding part and sliding rail at the rear end of the drawer to make the bottom plate of the drawer fit more tightly against the bottom plate of the storage space, further improving the heat exchange efficiency between the refrigeration module and the storage space.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0045] Combination Figure 1-8 As shown, this embodiment of the present disclosure provides a refrigerator, including a cabinet 100, a refrigeration module 200, a sliding rail 300, a drawer 400, a sliding part 500, and a pressing component 600. The cabinet 100 has an accommodating space with an open front side. The refrigeration module 200 is used to reduce the temperature of the bottom plate of the accommodating space. The sliding rail 300 is disposed on the side wall of the accommodating space, and its second section is inclined downwards. The drawer 400 is slidably disposed in the accommodating space. The sliding part 500 extends outwards from the side wall of the drawer 400 and cooperates with the sliding rail 300. When the sliding part 500 slides from front to back to the second section of the sliding rail 300, the refrigerator drawer 400 moves downwards to press against the bottom plate of the accommodating space. The pressing component 600 is used to press the front end of the drawer 400 downwards when the sliding part 500 slides to the second section of the sliding rail 300.

[0046] In this embodiment, the housing 100 includes an outer shell 110 and an inner liner 120, with the inner liner 120 located within the outer shell 110 and enclosing a storage space. The bottom plate of the inner liner 120 and the bottom plate of the outer shell 110 form a sandwich layer, within which a refrigeration module 200 is disposed. Exemplarily, the refrigeration module 200 is one of the following: an evaporator of a refrigerant circulation system, the cold end of a Stirling refrigerator, or the cold end of a semiconductor refrigeration device. The cooling capacity of the refrigeration module 200 is transferred to the storage space through the bottom plate of the inner liner 120 to reduce the temperature of the storage space. As a preferred embodiment, the refrigeration module 200 is attached to the bottom plate of the inner liner 120, and the heat transfer is via thermal conduction. Compared to heat convection or heat radiation, thermal conduction has higher thermal conductivity, thus better reducing the temperature of the storage space.

[0047] The sliding rail 300 is installed on the side wall of the accommodating space, and the drawer 400 is slidably connected to the sliding rail 300 via the sliding part 500. The drawer 400 is a pull-out type, which facilitates the user's access to and from items. Especially when the temperature of the accommodating space is low and the drawer 400 is relatively deep, pulling out the drawer 400 to access items saves operation time compared to the user reaching into the accommodating space to search for items, and avoids occupational hazards caused by the user's arms being exposed to a low-temperature environment for a long time. The drawer 400 is slidably connected to the side wall of the accommodating space, and the drawer 400 does not contact the bottom plate of the inner liner 120 during the pulling-out process, thus avoiding wear and tear on the bottom plate of the inner liner 120 and the bottom plate of the drawer 400.

[0048] Optionally, the refrigerator's inner liner 120 includes an inner liner body and a track bar, the track bar being fitted to the side wall of the inner liner body, and a sliding track 300 being constructed on the track bar.

[0049] The refrigerator drawer 400 has a push-back state and a pull-out state. When the drawer 400 is pulled out, it extends out of the accommodating space to facilitate the user's access to frozen items. When the drawer 400 is pushed back, its bottom plate is pressed against the bottom plate of the accommodating space to improve the heat transfer efficiency between the refrigeration module 200 and the frozen items.

[0050] The sliding track 300, from front to back, consists of two sections: a first section and a second section. The second section of the sliding track 300 slopes downwards. When the drawer 400 is pushed back into the accommodating space, the sliding part 500 slides to the second section of the sliding track 300, causing the refrigerator drawer 400 to move backwards and downwards. When the drawer 400 slides to its final position, its bottom plate is in contact with the bottom plate of the accommodating space, that is, with the upper surface of the bottom plate of the inner liner 120. With this arrangement, the frozen items placed in the drawer 400 exchange heat with the bottom plate of the inner liner 120 through the bottom plate of the drawer 400. This heat exchange is through conduction, which is more efficient than convection or radiation, resulting in higher freezing efficiency for the items. Furthermore, the close contact between the bottom plate of the drawer 400 and the bottom plate of the inner liner 120 prevents frost buildup on the contact surface. After freezing, the drawer 400 can be smoothly pulled out.

[0051] Drawer 400 is pull-out type. To allow for a certain sliding travel, the sliding part 500 is located at the rear end of drawer 400. The pressing component 600 is located at the front end of drawer 400 and is used to press the front end of drawer 400 downward. This allows the bottom plate of drawer 400 to fit more tightly with the bottom plate of inner liner 120. This further enhances heat transfer between the bottom plate of drawer 400 and the bottom plate of inner liner 120 for frozen items and prevents frost from forming on the bottom plate of drawer 400.

[0052] The refrigerator provided in this embodiment of the present disclosure is equipped with a drawer 400, which facilitates the user in taking out and putting away frozen items from the refrigerator. The drawer 400 does not contact the bottom plate of the accommodating space during the sliding process, which can avoid scratching the bottom plate of the drawer 400 or the bottom plate of the accommodating space. The second section of the sliding track 300 is inclined downward, so when the drawer 400 is pushed back, the bottom plate of the drawer 400 is pressed against the bottom plate of the accommodating space. This can improve the heat exchange efficiency between the refrigeration module 200 and the accommodating space and prevent the formation of frost between the drawer 400 and the bottom plate of the accommodating space. The front end of the drawer 400 is provided with a pressing component 600, which can cooperate with the sliding part 500 at the rear end of the drawer 400 and the sliding track 300 to make the bottom plate of the drawer 400 fit more tightly against the bottom plate of the accommodating space, further improving the heat exchange efficiency between the refrigeration module 200 and the accommodating space.

[0053] Optionally, the pressing assembly 600 includes a rotating shaft 610, a locking member 620, and a locking pin 630. The rotating shaft 610 extends inward from the side wall of the accommodating space. The locking member 620 is rotatably connected to the rotating shaft 610. The first end of the locking member 620 is constructed with a snap-fit ​​groove 622, and the second end is a rotating handle 621. The locking pin 630 extends outward from the side wall of the drawer 400. When the sliding part 500 slides to the second section of the sliding track 300, the locking pin 630 snaps into the snap-fit ​​groove 622 and makes an arc motion under the constraint of the locking member 620. When the locking pin 630 makes an arc motion, it drives the front end of the drawer 400 to move downward.

[0054] The relative position of the rotating shaft 610 and the inner liner 120 remains fixed, and the rotating shaft 610 extends inward from the side wall of the inner liner 120. The locking member 620 is rotatably connected to the rotating shaft 610, and the locking member 620 rotates in a vertical plane about the rotating shaft 610. A through rotating hole is provided in the middle of the locking member 620, and the rotating shaft 610 extends into the rotating hole. The portion of the first end of the locking member 620 extending to the rotating hole is the first end of the locking member 620, and the portion of the second end of the locking member 620 extending to the rotating hole is the second end of the locking member 620. The locking pin 630 extends outward from the side wall of the drawer 400, and the locking pin 630 is located at the front end of the drawer 400. The first end of the locking member 620 is constructed with a snap-fit ​​groove 622, and when the sliding part 500 slides to the second section of the sliding track 300, the locking pin 630 snaps into the snap-fit ​​groove 622 of the locking member 620. Continue pushing drawer 400 backward, and locking pin 630 moves in an arc under the constraint of locking groove 622. While moving backward, locking pin 630 also moves downward. The front end of drawer 400 is rigidly connected to locking pin 630, so the front end of drawer 400 moves downward while moving backward, thereby further pressing the bottom plate of drawer 400 against the bottom plate of the accommodating space, that is, against the bottom plate of inner liner 120.

[0055] With this configuration, the rear end of drawer 400, constrained by sliding rail 300, presses downward against the bottom plate of inner liner 120, while the front end of drawer 400, constrained by locking groove 622, presses downward against the bottom plate of inner liner 120. This tighter fit between the bottom plates of drawer 400 and inner liner 120 further improves heat exchange efficiency and reduces frost buildup. During the retraction of drawer 400, locking pin 630 engages with locking groove 622 of locking element 620. The downward pressing of the front end of drawer 400 is automatic during this process, facilitating user operation. Furthermore, the second end of locking element 620 is a rotating handle 621, allowing the user to hold the handle and rotate the locking element 620 to press down and lift the front end of drawer 400. When pushing drawer 400 back, turning the handle 621 presses the front end of drawer 400 downwards, ensuring the bottom of drawer 400 is flush against the bottom of inner liner 120. When pulling drawer 400 out, turning the handle 621 lifts the front end of drawer 400. When lifting the front end of drawer 400, the drawer itself acts as a lever with the sliding part 500 as a fulcrum, allowing the frost layer that hinders the refrigerator's movement to peel off quickly, thus enabling the refrigerator drawer 400 to be pulled out smoothly.

[0056] Optionally, the length of the rotating handle 621 is greater than the distance between the rotating hole and the locking groove 622.

[0057] With this design, using the rotating shaft 610 as a fulcrum, the locking element 620 itself acts as a force-saving lever. The user can lift the front end of the refrigerator drawer 400 more easily by holding the rotating handle 621, further removing the frost layer condensed between the refrigerator bottom plate and the inner liner 120, thus allowing the refrigerator drawer 400 to be pulled out smoothly. This design further enhances user convenience.

[0058] Optionally, the locking member 620 can rotate between a first angle and a second angle. When the locking member 620 rotates from the first angle to the second angle, the front end of the drawer 400 moves downward. When the locking member 620 rotates from the second angle to the first angle, the front end of the drawer 400 is lifted upward. The locking member 620 is provided with a locking pin 641. When the locking pin 641 extends, it fixes the locking member 620 at the second angle to lock the drawer 400.

[0059] When drawer 400 is pushed back, locking member 620 rotates from the first angle to the second angle, pressing the front end of drawer 400 downwards; when drawer 400 is pulled out, locking member 620 rotates from the second angle to the first angle, lifting the front end of drawer 400 upwards. Locking member 620 is equipped with a locking pin 641, which is retractable. When the locking pin 641 extends, it fixes locking member 620 at the second angle. With locking member 620 fixed at the second angle, the position of locking pin 630 remains fixed. The pressing component 600 presses the front end of drawer 400 downwards and holds drawer 400 in the pushed-back position, facilitating the push-back positioning of drawer 400 and preventing drawer 400 from being pulled out uncontrollably. With this configuration, the pressing component 600 not only improves the heat exchange between the bottom plate of drawer 400 and the bottom plate of inner liner 120, but also locks drawer 400 in the pushed-back state, further facilitating user operation.

[0060] Optionally, the locking member 620 includes a base fixed to the inner wall of the accommodating space. The base has a rotating groove. The first end of the locking member 620 rotates within the rotating groove. The locking member 620's snap-fit ​​groove 622 engages with the inner wall of the rotating groove to limit the movement of the locking pin 630.

[0061] The latching slot 622 has a notch to allow the latching pin to move in and out. After the latching pin engages with the latching slot 622, the locking member 620 rotates, and the notch in the latching slot 622 is stopped by the inner wall of the rotating groove to prevent the locking pin 630 from disengaging from the latching slot 622. When the locking member 620 returns to the first angle, the notch in the latching slot 622 is no longer stopped by the inner wall of the rotating groove, and pulling the drawer 400 forward will disengage the latching pin from the latching slot 622. With this arrangement, the movement of the locking pin 630 is more controlled, and the pressing component 600 can better press the front end of the drawer 400 downward or upward through the locking pin 630.

[0062] Optionally, the side wall of the accommodating space is provided with a slot, and a locking pin is retractably and laterally disposed in the locking member, extending into the slot when the locking pin is extended.

[0063] When the locking pin extends, it engages with the slot to restrict the rotation of the locking mechanism, thereby limiting the drawer's movement in both the front-to-back and up-to-down directions. This design simplifies the structure and reduces the cost of the refrigerator.

[0064] Optionally, the slot 642 is provided on the base, and the locking pin 641 is provided along the length direction of the rotating handle 621. When the locking pin 641 is rotated to the second angle, the locking pin 641 extends out and inserts into the slot 642.

[0065] This design simplifies the structure of the refrigerator's inner liner and reduces the refrigerator's cost.

[0066] Optionally, the base of the locking element 620 is integrally formed with the track bar.

[0067] The locking component 620 is located at the front end of the sliding rail 300. The base of the locking component 620 is integrally formed with the rail strip, which can simplify the manufacturing and assembly process of the refrigerator and reduce the cost of the refrigerator.

[0068] Optionally, the sliding track 300 includes a first sliding groove 310 and a second sliding groove 320, wherein the first sliding groove 310 is formed in the side wall of the accommodating space, with the first section being straight and the second section sloping downward; the second sliding groove 320 is formed in the side wall of the accommodating space, with the first section being straight and the second section sloping downward; the sliding part 500 includes a first sliding post 510 and a second sliding post 520, wherein the first sliding post 510 cooperates with the first sliding groove; and the second sliding post 520 cooperates with the second sliding groove.

[0069] The first sliding post 510 is located behind the second sliding post 520. The first sliding post 510 cooperates with the first slide groove 310, and the second sliding post 520 cooperates with the second slide groove 320. When the pressing component 600 does not press down the front end of the drawer 400, the relative height of the first sliding post 510 and the second sliding post 520 determines the angle of the drawer 400. For example, the relative positions of the first sliding post 510 and the second sliding post 520 remain fixed. When the drawer 400 is pulled out, the first sliding post 510 and the second sliding post 520 together provide support for the drawer 400, keeping the drawer 400 at a certain angle and preventing it from tipping up or down. During the process of pushing the drawer 400 back, when the sliding part 500 is located at the first end of the sliding track 300, the first sliding post 510 and the second sliding post 520 together act on the drawer 400, so that there is a certain distance between the drawer 400 and the bottom plate of the inner liner 120 during the process of pushing back. When the sliding part 500 is in the second section of the sliding track 300, the first sliding post 510 moves backward and downward, the second sliding post 520 moves backward and downward, and the drawer 400 moves backward and downward to fit against the bottom plate of the inner liner 120. This arrangement allows the drawer 400 to better maintain the preset angle during sliding.

[0070] Optionally, the depth of the first slide groove 310 is greater than the depth of the second slide groove 320, the length of the first sliding post 510 is greater than the length of the second sliding post 520, the first section of the second slide groove 320 coincides with the first slide groove 310, and the second section of the second slide groove 320 forms a step 321 with the first slide groove 310.

[0071] Combination Figure 7 , 8As shown, the first slide groove 310 and the second slide groove 320 partially overlap, which simplifies the structure of the sliding track 300 and facilitates the manufacturing of the inner liner 120. The first sliding post 510 is located behind the second sliding post 520. The rear end of the first slide groove 310 extends rearward beyond the rear end of the second slide groove 320, and the front end of the first slide groove 310 extends rearward beyond the front end of the second slide groove 320. The length of the first sliding post 510 matches the depth of the first slide groove 310, and the length of the second sliding post 520 matches the depth of the second slide groove 320. The length of the first sliding post 510 is greater than the length of the second sliding post 520, and the depth of the first slide groove 310 is greater than the depth of the second slide groove 320. The first sliding post 510 can only slide within the first slide groove 310, while the second sliding post 520 can slide within both the first and second slide grooves 310 and 320. In the overlapping portion of the first slide groove 310 and the second slide groove 320, the shallower second slide groove 320 is absorbed by the first slide groove 310, so from the user's perspective, only the first slide groove 310 is visible. The second section of the second slide groove 320 slopes downwards, while the corresponding section of the first slide groove 310 remains straight, forming a step 321 with the first slide groove 310. This arrangement simplifies the structure of the sliding track 300 and reduces the manufacturing cost of the inner liner 120.

[0072] Optionally, the refrigerator also includes a spring top bead 521, which is telescopically disposed at the end of the second sliding post 520. When the second sliding post 520 is located in the first section of the second sliding groove 320, the spring top bead 521 elastically presses against the bottom of the first sliding groove 310. When the second sliding post 520 is located in the second section of the second sliding groove 320, the spring top bead 521 elastically presses against the step 321.

[0073] When the first sliding column 510 slides within the first slide groove 310, its end abuts against the bottom of the first slide groove 310, thereby restricting the left-right movement of the drawer 400 to prevent it from wobbling. The end of the second sliding column 520 is equipped with a spring-loaded ball 521. The second sliding column 520 abuts against the bottom of the first slide groove 310 via the spring-loaded ball 521, thus, together with the first sliding column 510, restricting the left-right movement of the drawer 400 to prevent it from wobbling. When the second sliding column 520 slides to the second section of the second slide groove 320, the spring-loaded ball 521 retracts under the pressure of the step 321, thus matching the overall length of the second sliding column 520 and the spring-loaded ball to the depth of the second slide groove 320. This arrangement allows the drawer 400 to slide parallel to each other during forward and backward movements, thereby improving the smoothness of the drawer 400's sliding motion.

[0074] Optionally, the step 321 is constructed with an inclined guide portion to guide the second sliding column 520 into the second section of the second groove 320.

[0075] This design allows for better extension and retraction of the spring top ball 521, further improving the smoothness of the drawer 400 when it is pulled out.

[0076] Optionally, the slope of the second section of the first slide rail 310 is less than the slope of the second section of the second slide rail 320, and the front end of the drawer 400 flips downward at a preset angle when the drawer 400 is pushed back.

[0077] When the first sliding post 510 enters the second section of the first slide groove 310, the second sliding post 520 enters the second section of the second slide groove 320. The distance that the first sliding post 510 and the second sliding post 520 move backward is equal to the distance that the drawer 400 moves backward. The slope of the second section of the first slide groove 310 is less than the slope of the second section of the second slide groove 320. When the drawer 400 moves backward, the distance that the first sliding post 510 moves downward is less than the distance that the second sliding post 520 moves downward. The second sliding post 520 is located in front of the first sliding post 510. The distance that the front end of the drawer 400 moves downward is greater than the distance that the rear end of the drawer 400 moves downward, meaning that the drawer 400 flips downward by a preset angle. Similarly, when the drawer 400 is pulled outward, the front end of the drawer 400 flips upward by a preset angle.

[0078] After the front end of drawer 400 is flipped downwards at a preset angle, drawer 400 is pressed against the bottom plate of inner liner 120. Before the front end of drawer 400 is flipped downwards at the preset angle, a certain angle is formed between drawer 400 and the bottom plate of inner liner 120. For example, this angle is equal to the preset angle at which the front end of drawer 400 can be flipped. On the one hand, the frozen objects are evenly placed in drawer 400, and drawer 400 is mainly kept straight by the sliding column at the rear end, while the front end of drawer 400 is easy to bend downwards. There is a certain inclination angle between the bottom plate of drawer 400 and the bottom plate of inner liner 120. When the sliding part 500 is in the first section of the sliding track 300, a certain distance can be better maintained between the bottom plate of drawer 400 and the bottom plate of inner liner 120. On the other hand, when drawer 400 is pulled out, the front end of drawer 400 can be flipped upwards, which can better peel off the frost layer between drawer 400 and bottom plate, so that drawer 400 can be pulled out smoothly.

[0079] Optionally, the lowest position of the second slide 320 is lower than the lowest position of the first slide 310.

[0080] During the sliding of drawer 400, the first sliding post 510 is constrained downward by the first slide groove 310, and the second sliding post 520 is constrained upward by the second slide groove 320. The first sliding post 510 and the second sliding post 520 are at the same distance from the bottom plate of drawer 400, and the lowest point of the second slide groove 320 is lower than the lowest point of the first slide groove 310. Thus, during the process of drawer 400 being pushed back, the front end of drawer 400 can tilt downward at a greater angle; correspondingly, during the process of drawer 400 being pulled out, the front end of drawer 400 can tilt upward at a greater angle. With this configuration, the second sliding post 520 has greater operating space, thereby increasing the tilting range of the front end of drawer 400, improving the frost removal capability of drawer 400, and facilitating user operation.

[0081] Optionally, there are two sliding rails 300, which are respectively provided on two opposite side walls of the accommodating space. There are also two sliding parts 500, which are respectively provided on two side panels of the drawer 400. The two sliding parts 500 correspond one-to-one with the two sliding rails 300.

[0082] A sliding part 500 is provided on the side panel of the inner liner 120 so that the bottom plate of the drawer 400 can fit tightly against the bottom plate of the inner liner 120. Sliding rails 300 are provided on two opposite side walls of the accommodating space, and two sliding parts 500 extend outward from the two side panels of the drawer 400 respectively. The two sliding parts 500 and the two sliding rails 300 cooperate with each other in a one-to-one manner, thus providing better support for the drawer 400 and guiding its sliding motion.

[0083] Optionally, the refrigerator also includes a defrosting device 700 for heating the bottom plate of the accommodating space.

[0084] When storing frozen items with high moisture content, frost inevitably forms on the inner walls of the storage space. When this frost adheres the bottom plate of drawer 400 to the bottom plate of inner liner 120, lifting the front of drawer 400 when the frost is thin can break it up, allowing the drawer to be pulled out smoothly. However, when the frost is thick, lifting the front of drawer 400 becomes difficult. In this case, activating the defrosting device 700 heats the bottom plate of inner liner 120, melting the frost at the boundary between the frost layer and the bottom plate. This allows the front of drawer 400 to be lifted smoothly, completely breaking up the frost layer and enabling the drawer to be pulled out easily. The defrosting device 700 further ensures the drawer 400 can be pulled out smoothly, improving user convenience.

[0085] Optionally, the defrosting device 700 includes an electric heating wire that is attached to the lower surface of the bottom plate of the inner liner 120.

[0086] Electric heating wires are low-cost and easy to install. This setup can quickly raise the temperature of the 120mm inner liner bottom plate.
