Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] Refrigerators are an indispensable household appliance. Some refrigerators have drawers in the freezer compartment at the bottom, which can be used to store larger frozen items and also allow for direct pulling out and putting in items.

[0003] In related technologies, the left and right sides of the freezer drawer are connected to the inner liner via guide rails. The guide rails not only support the freezer drawer but also guide its pulling out.

[0004] When the freezer drawer of a refrigerator is pulled out, the front door of the freezer drawer is suspended and swings at a large angle, causing the drawer to wobble and affecting the stability of the stored items. Utility Model Content

[0005] This application provides a refrigerator to improve the stability of the freezer drawer when it is pulled out.

[0006] This application provides a refrigerator, which includes:

[0007] The box body is constructed to form a storage compartment with a front opening; the storage compartment has compartment side walls that are opposite to and spaced apart along the width direction of the box body, and a compartment bottom wall disposed at the bottom end of the compartment side walls; the compartment side walls are provided with a first guide rail extending along the depth direction of the box body;

[0008] A drawer is installed in the storage compartment in a way that allows it to be pulled out along the depth direction of the box body; the drawer is constructed to form an upward-opening storage cavity; the drawer has drawer sidewalls that are disposed opposite to each other along the width direction of the box body; the drawer sidewalls are provided with a second guide rail that slides and engages with the first guide rail;

[0009] The compartment bottom wall is provided with a third guide rail extending along the depth direction of the box body, and the drawer bottom wall is provided with a fourth guide rail that cooperates with the third guide rail; when the drawer is pulled out, the cooperation length between the fourth guide rail and the third guide rail is greater than the cooperation length between the second guide rail and the first guide rail.

[0010] In this embodiment, the drawer and storage compartment are connected by a first and second guide rail on the left side, a first and second guide rail on the right side, and a third and fourth guide rail on the bottom side. This creates a three-sided guide rail connection, forming a triangular three-dimensional support structure. This structure enhances the support provided by the storage compartment to the drawer, especially after the drawer is pulled out, making it more stable and reducing swaying and shaking. When the drawer is pulled out, the length of the fourth and third guide rails is greater than the length of the second and first guide rails, providing longer support between the bottom wall of the compartment and the bottom wall of the drawer. This support is directed towards the drawer's weight, further supporting the drawer and reducing swaying and shaking during pull-out, thus improving the drawer's stability.

[0011] In some embodiments of this application, a first limiting member is provided at the front end of the first guide rail, and the first limiting member is configured to abut against the rear end of the second guide rail to limit the pull-out stroke of the drawer.

[0012] When the first limiting member abuts against the rear end of the second guide rail, the engagement length between the fourth guide rail and the third guide rail is 10mm to 15mm.

[0013] In this embodiment, by setting the engagement length between the fourth guide rail and the third guide rail to 10mm to 15mm, it can be ensured that the third guide rail has sufficient support for the drawer when the drawer is pulled out, thereby improving the stability of the drawer; it can also be ensured that the second guide rail and the first guide rail have sufficient engagement length when the drawer is closed, thereby ensuring the stability of the drawer.

[0014] In some embodiments of this application, the storage compartment is provided with a second limiting member, which is configured to abut against the drawer when the drawer is pushed into the storage compartment.

[0015] This application embodiment, by setting a second limiting member in the storage room, restricts the position of the drawer when it is pushed into the room, thus avoiding the collision force generated by the drawer directly abutting against the back wall of the room.

[0016] In some embodiments of this application, the second limiting member has an elastic portion configured to elastically abut against the drawer.

[0017] This design allows the second limiting component to make elastic contact with the drawer, which helps to buffer the collision force between the second limiting component and the drawer and avoids noise caused by rigid contact between the second limiting component and the drawer.

[0018] In some embodiments of this application, the fourth guide rail is detachably connected to the bottom wall of the drawer.

[0019] This design allows the drawer to be separated from the fourth guide rail when it is disassembled, resulting in a relatively flat bottom wall for the disassembled drawer, which is beneficial for its placement.

[0020] In some embodiments of this application, one of the drawer bottom wall and the fourth guide rail is provided with a connecting part, and the other is provided with a recessed part, wherein the connecting part and the recessed part are inserted into each other along the height direction of the box body.

[0021] The fourth guide rail and the bottom wall of the drawer in this embodiment are connected by a protruding connecting part and a recessed part, which is simple in structure and easy to implement.

[0022] In some embodiments of this application, multiple connecting portions are provided, and the multiple connecting portions are arranged symmetrically about the central axis of the fourth guide rail; the central axis of the fourth guide rail extends along the depth direction of the housing, and the fourth guide rail is symmetrical about the central axis;

[0023] The recessed portion is provided in multiple ways, and each of the connecting portions is inserted into one of the recessed portions.

[0024] In this embodiment, by setting multiple connecting parts, the reliability of the connection between the drawer bottom wall and the fourth guide rail is improved; by setting multiple connecting parts symmetrically arranged about the central axis of the fourth guide rail, the forces on both sides of the drawer bottom wall along the width direction are balanced, which helps to improve the stability of the drawer.

[0025] In some embodiments of this application, a portion of the bottom wall of the compartment protrudes upward to form a mounting platform, and the third guide rail is fixed to the mounting platform.

[0026] The mounting platform provides guidance for the installation of the third guide rail. Furthermore, by installing the mounting platform, it prevents the bottom wall of the drawer from deforming downwards and contacting the bottom wall of the compartment when too many items are placed inside, thus avoiding interference with the smoothness of pulling out the drawer.

[0027] In some embodiments of this application, the third guide rail is fixed at the middle position of the bottom wall of the compartment along the width direction of the box.

[0028] This design improves the balance of the third guide rail's support for the drawer along the width direction, reducing the possibility of the drawer becoming unbalanced along the width direction.

[0029] In some embodiments of this application, ball bearings are provided between the third guide rail and the fourth guide rail.

[0030] This application embodiment reduces the friction between the third and fourth guide rails by setting ball bearings between them, thereby reducing the drawer's pulling resistance and improving the smoothness of the drawer's operation. Attached Figure Description

[0055] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0056] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0057] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0058] French-style refrigerators are favored by consumers because their bottom freezer drawers have a large freezing space, allowing for the storage of larger volumes of food.

[0059] In related technologies, the left and right sides of the freezer drawer are connected to the refrigerator liner via guide rails. These rails not only support the freezer drawer but also guide its pulling out. When the freezer drawer is pulled out, the front door is suspended and swings at a significant angle, causing the drawer to wobble and affecting the stability of stored items. In particular, when the freezer drawer is pulled out to its maximum extension, the front end is in a free state due to its suspension. Because of the weight of the front door and the amount of stored items, the door has a large swing angle; the greater the extension, the larger the swing angle, resulting in noticeable wobbling.

[0060] In view of this, this application provides a refrigerator in which the freezer drawer has guide rails on the left and right sides and a slide rail on the bottom surface of the freezer drawer to form a triangular sliding support structure, which improves the support of the freezer drawer and reduces the swinging and shaking of the freezer drawer.

[0061] Furthermore, the sliding fit length between the slide rail and the cabinet is greater than the fit length of the left and right side guide rails. When the freezer drawer is pulled out to its maximum stroke, the bottom surface of the freezer drawer still slides with the bottom surface of the cabinet liner, which improves the support for the freezer drawer and thus improves the stability of the freezer drawer when it is opened.

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0063] First, it should be noted that in this embodiment, the depth direction of the box corresponds to the Y-axis direction in the figures, and the directional term "front" refers to the side facing the door along the Y-axis direction, while the directional term "rear" refers to the side away from the door along the Y-axis direction. The width direction of the box corresponds to the X-axis direction in the figures, and the height direction of the box corresponds to the Z-axis direction in the figures.

[0064] Reference Figure 1 and Figure 2 This application provides a refrigerator, which includes a cabinet 100. The cabinet 100 can be configured to form a storage compartment 101 with a front opening for storing items. The front opening of the storage compartment 101 is a retrieval port.

[0065] Multiple storage compartments 101 can be provided to expand storage space. Depending on the storage temperature, each storage compartment 101 may include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigerated mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in frozen mode.

[0066] In some possible implementations, at least one of the storage chambers 101 may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0067] For example, two storage compartments 101 can be provided, which can be stacked vertically or arranged side by side horizontally. One of them can be a refrigerator compartment and the other can be a freezer compartment.

[0068] The refrigerator body 100 may include a refrigerator liner 110 and a refrigerator shell. The refrigerator liner 110 may be configured to form a storage compartment 101 with a front opening, which serves as an access port. The refrigerator shell may be attached to the outside of the refrigerator liner 110 to form the appearance of a refrigerator.

[0069] The cabinet 100 may also include a cabinet insulation layer, which can be disposed between the cabinet liner 110 and the cabinet shell. The cabinet insulation layer can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigerator, which helps to ensure the cooling effect of the refrigerator.

[0070] The refrigerator in this embodiment may further include a refrigeration system for reducing the air temperature in the storage compartment 101. Exemplarily, the refrigeration system may be housed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0071] During refrigeration system operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside storage compartment 101.

[0072] Continue to refer to Figure 1 The refrigerator in this embodiment may further include a door 200, which is rotatably connected to the cabinet 100 to open or close the access port. Exemplarily, the door 200 is hinged to the cabinet 100.

[0073] Each storage room 101 may be provided with one door 200; or, each storage room 101 may be provided with two doors 200, which may rotate in opposite directions to open or close the storage room 101.

[0074] In some embodiments, the door 200 may include an inner door liner. When the door 200 is closed to the refrigerator compartment, the inner door liner faces the refrigerator compartment.

[0075] The door 200 may include a door outer shell; the door outer shell may be attached to the outside of the door inner liner to form the appearance of the door 200. The door outer shell may be rotatably connected to the cabinet 100 to allow the door 200 to open or close the refrigerator compartment.

[0076] The door 200 may also include a door insulation component, which can be disposed within the gap between the inner door liner and the outer door shell. The door insulation component insulates the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigerator, thus ensuring the refrigerator's cooling effect. The door insulation component can be a foam layer.

[0077] Continue to refer to Figure 1 and Figure 2 In this embodiment of the application, a drawer 300 is provided in the storage compartment 101, and the outer end of the drawer 300 is constructed to form a drawer door. Exemplarily, a freezer drawer is provided in the freezer compartment, and the freezer drawer is pulled out along the depth direction relative to the freezer compartment to open and close the freezer compartment.

[0078] In this embodiment, the structure of the drawer slide is described using a drawer in the freezer compartment as an example. However, this is not limiting. For example, in some refrigerators, the drawer in the variable temperature compartment can also be equipped with the drawer slide structure of this embodiment; furthermore, in some refrigerators, a refrigerator drawer is provided in the bottom space of the refrigerator compartment, and the drawer slide structure of this embodiment can also be provided there. The structure of the drawer slide in this embodiment is described in detail below.

[0079] First, combined Figure 3 The storage compartment 101 has a width direction along the box body 100 (corresponding to Figure 3 The compartment sidewalls 111 are arranged opposite to each other and spaced apart in the X-axis direction, and the compartment bottom wall 112 is provided at the bottom end of the compartment sidewalls 111.

[0080] Storage compartment 101 also has a top wall 113 and a rear wall 114, the top wall 113 and the bottom wall 112 of the compartment along the height direction of the box body 100 (corresponding to Figure 3 The compartments are spaced apart in the Z-axis direction. The rear wall 114 of the compartment is connected to the rear end of the top wall 113, the bottom wall 112, and the two side walls 111 of the compartment, thus forming a storage compartment 101 with a front opening.

[0081] In this embodiment of the application, the left and right side walls of the box liner 110 form two compartment side walls 111, the bottom wall of the box liner 110 forms a compartment bottom wall 112, the top wall of the box liner 110 forms a compartment top wall 113, and the rear wall of the box liner 110 forms a compartment rear wall 114.

[0082] In this embodiment, the drawer 300 is installed in the storage compartment 101 in a pull-out manner along the depth direction of the box 100; the drawer 300 is configured to form an upward-opening storage cavity 301.

[0083] Drawer 300 has drawer sidewalls 311 disposed opposite to each other along the width direction of the box body 100.

[0084] Drawer 300 also has a drawer bottom wall 312, which is connected to the bottom end of the drawer side wall 311. The bottom surface of the drawer bottom wall 312 may be provided with reinforcing ribs, which may be in the form of a grid, to improve the structural strength of drawer 300 and reduce the possibility of the drawer bottom wall 312 deforming downwards due to too many items placed on it.

[0085] Drawer 300 may also have a drawer rear wall 313, which is connected to the rear end of the drawer side wall 311 and the drawer bottom wall 312.

[0086] Drawer 300 may have a front wall, which is connected to the front end of the drawer side wall 311 and the drawer bottom wall 312. Thus, the front wall, the rear wall, the bottom wall, and the two side walls together form an upward-opening storage cavity 301.

[0087] Among them, combined Figure 3 The drawer 300 may include a drawer door 320 and a drawer body 310, the drawer body 310 being configured to form an upward-opening storage cavity 301. The drawer door 320 is fixed to the front side of the drawer body 310. When the drawer 300 is pushed into the storage compartment 101, the drawer door 320 seals against the cabinet 100 to close the storage compartment 101 where the drawer 300 is located.

[0088] Combination Figure 4 The drawer body 310 includes a drawer bottom wall 312, two drawer side walls 311, a drawer front wall, and a drawer rear wall 313. The drawer door 320 is fixed to the front side of the drawer front wall. In some embodiments, the drawer body 310 is configured to form the drawer front wall.

[0089] Combination Figure 3 The side wall 111 of the compartment is provided along the depth direction of the box 100 (corresponding to Figure 3 A first guide rail 115 extends along the Y-axis, and a second guide rail 314 is provided on the drawer side wall 311 to slide in cooperation with the first guide rail 115. Through the cooperation between the second guide rail 314 and the first guide rail 115, the drawer 300 can be pulled out and slid along the depth direction relative to the storage compartment 101.

[0090] In the embodiments of this application, reference is made to Figure 5 A third guide rail 116 extending along the depth direction of the box 100 is provided on the bottom wall 112 of the compartment; combined with Figure 4 The bottom wall 312 of the drawer is provided with a fourth guide rail 315 that cooperates with the third guide rail 116. Through the cooperation of the fourth guide rail 315 and the third guide rail 116, the guiding effect of the drawer 300 in the direction of pulling out is improved, and the supporting effect of the bottom wall 112 of the compartment being lower than the drawer 300 is increased.

[0091] The third guide rail 116 can be configured to form a downward-opening groove, so that a portion of the fourth guide rail 315 is accommodated within the third guide rail 116, allowing the third guide rail 116 to slide relative to the fourth guide rail 315. The groove can be a rectangular groove, a dovetail groove, or the like.

[0092] Reference Figure 6 and Figure 7 Through the above arrangement, the drawer 300 and the storage compartment 101 form a cooperation between the first guide rail 115 and the second guide rail 314 on the left side, the first guide rail 115 and the second guide rail 314 on the right side, and the third guide rail 116 and the fourth guide rail 315 on the bottom side. This makes the drawer 300 and the storage compartment 101 form a three-sided guide rail cooperation, forming a triangular three-dimensional support structure. This helps to improve the support of the storage compartment 101 for the drawer 300. Especially after the drawer 300 is pulled out, the triangular three-dimensional support structure makes the drawer 300 more stable and helps to reduce the swinging and shaking of the drawer 300.

[0093] In this embodiment of the application, when the drawer 300 is pulled out, the engagement length of the fourth guide rail 315 and the third guide rail 116 is greater than the engagement length of the second guide rail 314 and the first guide rail 115.

[0094] The mating length refers to the overlap length of the two guide rails. When drawer 300 is closed, the mating lengths of the first guide rail 115 and the second guide rail 314 are at their maximum, as are the mating lengths of the third guide rail 116 and the fourth guide rail 315. As drawer 300 is pulled outward, the mating lengths of the first guide rail 115 and the second guide rail 314, and the mating lengths of the third guide rail 116 and the fourth guide rail 315, gradually decrease. When drawer 300 is pulled outward to its maximum position, the mating lengths of the first guide rail 115 and the second guide rail 314 are at their minimum, as are the mating lengths of the third guide rail 116 and the fourth guide rail 315.

[0095] In this embodiment, when the drawer 300 is pulled out, the cooperation length between the fourth guide rail 315 and the third guide rail 116 is set to be greater than the cooperation length between the second guide rail 314 and the first guide rail 115, so that there is a longer support between the bottom wall 112 of the compartment and the bottom wall 312 of the drawer, and the support force is in the direction of gravity of the drawer 300, which can better support the drawer 300, further reduce the swing and shaking of the drawer 300 when it is pulled out, and help to further improve the stability of the drawer 300 when it is pulled out.

[0096] Combination Figure 3 In some embodiments of this application, a first limiting member 1151 is provided at the front end of the first guide rail 115. The first limiting member 1151 is configured to abut against the rear end of the second guide rail 314 to limit the pull-out stroke of the drawer 300.

[0097] For example, the first limiting member 1151 may be a first roller disposed at the front end of the first guide rail 115, and the first roller is rotatably mounted at the front end of the first guide rail 115.

[0098] The rear end of the second guide rail 314 is rotatably provided with a second roller 3141, which is configured to abut against the first roller when the drawer 300 is pulled out to its maximum stroke, so as to limit the pull-out stroke of the drawer 300.

[0099] By abutting the second roller 3141 against the first roller, not only can the pull-out stroke of the drawer 300 be limited, but the drawer 300 can also be made easier to disassemble.

[0100] When the first limiting member 1151 abuts against the rear end of the second guide rail 314, the engagement length between the fourth guide rail 315 and the third guide rail 116 is 10mm to 15mm.

[0101] If the mating length between the fourth guide rail 315 and the third guide rail 116 is less than 10mm, the mating length between the fourth guide rail 315 and the third guide rail 116 will be small, which will reduce the supporting force of the third guide rail 116 on the drawer 300, thus affecting the stability of the drawer 300 when it is pulled out.

[0102] If the mating length between the fourth guide rail 315 and the third guide rail 116 is greater than 15mm, the rear ends of the first guide rail 115 and the second guide rail 314 will have a gap from the rear wall 114 of the compartment when the drawer 300 is closed, which will affect the stability of the drawer 300 when it is closed.

[0103] Therefore, in this embodiment of the application, by setting the engagement length between the fourth guide rail 315 and the third guide rail 116 to 10mm to 15mm, it can be ensured that when the drawer 300 is pulled out, the third guide rail 116 has sufficient support for the drawer 300 to improve the stability of the drawer 300; it can also be ensured that when the drawer 300 is closed, the second guide rail 314 and the first guide rail 115 have sufficient engagement length to ensure the stability of the drawer 300.

[0104] In some embodiments of this application, a second limiting member is provided in the storage compartment 101, and the second limiting member is configured to abut against the drawer 300 when the drawer 300 is pushed into the storage compartment 101.

[0105] For example, a second limiting member is provided on the rear wall 114 of the compartment. When the drawer 300 is pushed into the storage compartment 101, the second limiting member abuts against the rear wall 313 of the drawer, reducing the collision force between the drawer 300 and the rear wall 114 of the compartment.

[0106] In some possible implementations, the second limiting member is disposed on the rear wall 114 of the compartment and is opposite to the fourth guide rail 315 along the depth direction of the cabinet 100. When the drawer 300 is pushed into the storage compartment 101, the second limiting member abuts against the fourth guide rail 315, thereby limiting the position of the drawer 300 in the storage compartment 101. This avoids the second limiting member abutting against the drawer body 310 and affecting the structural strength of the drawer body 310.

[0107] In this embodiment of the application, by setting a second limiting member in the storage compartment 101, the position of the drawer 300 being pushed into the compartment can be restricted, thereby avoiding the collision force generated by the drawer 300 directly contacting the rear wall 114 of the compartment.

[0108] In some implementations, the second limiting member has an elastic portion configured to elastically abut against the drawer 300. The elastic portion may be a rubber sleeve, rubber head, or the like located at the end of the second elastic member; alternatively, the second limiting member may include a spring, the end of which is connected to an abutment for elastic contact with the drawer 300.

[0109] This design allows the second limiting member to make elastic contact with the drawer 300, which helps to buffer the collision force between the second limiting member and the drawer 300 and avoids noise caused by rigid contact between the second limiting member and the drawer 300.

[0110] In some embodiments of this application, the fourth guide rail 315 is detachably connected to the bottom wall 312 of the drawer. This arrangement allows the drawer 300 to be separated from the fourth guide rail 315 when it is disassembled, thereby giving the disassembled drawer 300 a relatively flat bottom wall, which is beneficial for placing the drawer 300.

[0111] For example, the fourth guide rail 315 is inserted into the drawer bottom wall 312 along the height direction, so that when the drawer 300 is removed from the storage compartment 101, the fourth guide rail 315 and the drawer 300 separate along the height direction; when the drawer 300 is installed into the storage compartment 101, the drawer bottom wall 312 and the fourth guide rail 315 are inserted into each other. Thus, during the disassembly and assembly of the drawer 300, no additional operation is required between the fourth guide rail 315 and the drawer bottom wall 312, making the disassembly and assembly of the drawer 300 more convenient.

[0112] In some implementations, the fourth guide rail 315 can also be connected to the bottom wall 312 of the drawer by screws, with the screws exposed in the storage cavity 301, so that the drawer 300 and the fourth guide rail 315 can be separated by removing the screws.

[0113] Alternatively, the fourth guide rail 315 is engaged with the bottom wall 312 of the drawer by a snap-fit ​​structure, and the snap-fit ​​structure is exposed in the storage cavity 301. When the drawer 300 is opened, the drawer 300 is separated from the fourth guide rail 315 by the snap-fit ​​structure.

[0114] It should be noted that when drawer 300 is pulled out to its maximum extension, drawer 300 can be removed from storage compartment 101.

[0115] Among some possible implementations, refer to Figure 8 and Figure 9 One of the drawer bottom wall 312 and the fourth guide rail 315 is provided with a recessed portion 3151, and the other is provided with a protruding connecting portion 3121, which is inserted into the recessed portion 3151. The connecting portion 3121 is inserted into the recessed portion 3151 along the height direction of the box body 100.

[0116] For example, the drawer bottom wall 312 is constructed with an upwardly recessed portion 3151, and the fourth guide rail 315 is provided with a protruding connecting portion 3121. Through the cooperation of the connecting portion 3121 and the recessed portion 3151, the drawer bottom wall 312 and the fourth guide rail 315 are connected. With this configuration, the bottom surface of the drawer bottom wall 312 has no protruding structure, which facilitates placement when the drawer 300 is disassembled.

[0117] For example, the drawer bottom wall 312 can be provided with a protruding connecting part 3121, and the fourth guide rail 315 can be provided with an upwardly opening recessed part 3151. Through the cooperation of the connecting part 3121 and the recessed part 3151, the drawer bottom wall 312 and the fourth guide rail 315 can be connected. This arrangement, with the protruding connecting part 3121 on the drawer bottom wall 312, helps to improve the structural strength of the drawer bottom wall 312.

[0118] For example, the recessed portion 3151 may be a hole or groove, etc.; the protruding connecting portion 3121 may be a column.

[0119] In some specific implementation methods, such as Figure 8 As shown, a protruding column is provided on the bottom wall 312 of the drawer to form a connecting part 3121; as Figure 9 As shown, the fourth guide rail 315 is provided with a mating hole to form a recess 3151; the bottom wall of the drawer 312 and the fourth guide rail 315 are detachably connected by inserting the column into the mating hole.

[0120] It should be noted that, in Figure 8 In the middle, the bottom surface of the drawer bottom wall 312 is provided with a recessed area 3122, and the protruding connecting part 3121 is provided in the recessed area 3122; the non-recessed area of ​​the drawer bottom wall 312 is provided with reinforcing ribs to improve the structural strength of the drawer bottom wall 312. The end of the connecting part 3121 does not protrude from the reinforcing ribs to avoid difficulty in placing the drawer 300 flat after disassembly.

[0121] The fourth guide rail 315 and the drawer bottom wall 312 in this embodiment are connected by a protruding connecting part 3121 and a recessed part 3151, which is simple in structure and easy to implement.

[0122] In some possible implementations, multiple connecting portions 3121 are provided, and the multiple connecting portions 3121 are symmetrically arranged about the central axis O of the fourth guide rail 315; the central axis of the fourth guide rail 315 extends along the depth direction of the housing 100, and the fourth guide rail 315 is symmetrical about the central axis. Correspondingly, multiple recesses 3151 are provided, and each connecting portion 3121 is inserted into one of the recesses 3151.

[0123] For example, four connecting parts 3121 are provided, and the four connecting parts 3121 are symmetrically arranged about the central axis O of the fourth guide rail 315.

[0124] In this embodiment, by providing multiple connecting parts 3121, the reliability of the connection between the drawer bottom wall 312 and the fourth guide rail 315 is improved; by providing multiple connecting parts 3121 symmetrically arranged about the central axis of the fourth guide rail 315, the forces on both sides of the drawer bottom wall 312 along the width direction are balanced, which helps to improve the stability of the drawer 300.

[0125] Combination Figure 5 In some possible implementations of this application, a portion of the bottom wall 112 of the compartment protrudes upward to form a mounting platform 1121, and a third guide rail 116 is fixed to the mounting platform 1121.

[0126] The mounting platform 1121 is flush with the platforms on both sides of the bottom wall 112 of the compartment in the width direction, providing support for the drawer 300. Furthermore, the mounting platform 1121 provides guidance for the installation of the third guide rail 116. Additionally, by setting the mounting platform 1121, when too many items are placed inside the drawer 300, the bottom wall 312 of the drawer is prevented from deforming downwards and contacting the bottom wall 112 of the compartment, thus avoiding interference with the smoothness of the drawer's movement.

[0127] The third guide rail 116 is fixed to the middle position of the bottom wall 112 of the compartment along the width direction of the box 100. The mounting platform 1121 is set at the middle position of the bottom wall 112 of the compartment along the width direction, so that the third guide rail 116 can be located at the middle position of the bottom wall 112 of the compartment along the width direction of the box 100.

[0128] This design improves the balance of the third guide rail 116's support for the drawer 300 along the width direction, reducing the possibility of the drawer 300 becoming unbalanced along the width direction.

[0129] Combination Figure 10 In some embodiments, a ball bearing 1161 is provided between the third guide rail 116 and the fourth guide rail 315.

[0130] For example, the third guide rail 116 and the fourth guide rail 315 have two contact surfaces opposite each other in the width direction, and ball bearings 1161 are provided between the two contact surfaces on the left and right sides.

[0131] Multiple balls 1161 can be provided, and the multiple balls 1161 are arranged at intervals along the length direction of the third guide rail 116. That is, the multiple balls 1161 are arranged at intervals along the depth direction of the housing 100.

[0132] In this embodiment of the application, a ball bearing 1161 is provided between the third guide rail 116 and the fourth guide rail 315 to reduce the friction between the third guide rail 116 and the fourth guide rail 315, thereby reducing the resistance to pulling out the drawer 300 and improving the smoothness of pulling out the drawer 300.
