Description

Technical Field

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

[0002] A refrigerator is a refrigeration device that keeps food or other items at a constant low temperature. The interior of a refrigerator typically has pull-out drawers for storing fruits, vegetables, and other food items.

[0003] In related technologies, refrigerator drawers typically include a box body and multiple support ribs extending in the push-pull direction at the bottom of the box body, with the support ribs contacting the bottom wall of the inner liner.

[0004] However, during the process of pushing and pulling the refrigerator drawers, hard friction occurs between the support ribs and the bottom wall of the inner liner, causing grooves to form on the bottom wall of the inner liner due to wear, affecting the appearance of the refrigerator; and dust and impurities will accumulate in the grooves and be difficult to remove, affecting the cleanliness of the refrigerator. Summary of the Invention

[0005] This application provides a refrigerator drawer and a refrigerator to solve the technical problem that grooves are formed on the bottom wall of the inner liner due to wear during the process of pushing and pulling the refrigerator drawer, which affects the appearance of the refrigerator; and that dust and impurities accumulate in the grooves and are difficult to remove, thus affecting the cleanliness of the refrigerator.

[0006] The first aspect of this application provides a refrigerator drawer located in the inner liner of a refrigerator body. The refrigerator drawer includes a box body and a mounting structure connected to the bottom of the box body. The mounting structure has a contact surface facing the bottom wall of the inner liner. The contact surface contacts the bottom wall to form at least one contact line. The extension direction of the contact line is perpendicular to the push-pull direction of the refrigerator drawer.

[0007] The refrigerator drawer of this embodiment features a mounting structure at the bottom of the drawer body. This mounting structure and the bottom wall of the inner liner form at least one contact line perpendicular to the drawer's push-pull direction. When the drawer is pushed or pulled, the contact line between the mounting structure and the bottom wall of the inner liner forms a contact plane. Compared to related technologies where the drawer and the bottom wall of the inner liner form a contact line parallel to the push-pull direction, and the contact line remains the same during the push-pull process, this embodiment, while ensuring smooth sliding within the inner liner, disperses the kinetic friction between the drawer and the bottom wall of the inner liner onto the contact plane formed between the mounting structure and the bottom wall of the inner liner, rather than concentrating it on the contact line. This reduces or eliminates wear on the bottom wall of the inner liner, avoids grooves, maintains the refrigerator's appearance, improves its ease of cleaning, and ultimately enhances product reliability.

[0008] In some possible implementations, the contact surface is at least one arcuate surface facing away from the bottom wall, and the axis of the arcuate surface is perpendicular to the push-pull direction of the refrigerator drawer.

[0009] With this design, the contact surface is an arc surface with its axis perpendicular to the direction of the refrigerator drawer's push and pull. When the refrigerator drawer is tilted during the push and pull process, it can still ensure that the contact surface and the bottom wall of the inner liner always form a contact line perpendicular to the direction of the refrigerator drawer's push and pull, thereby reducing or eliminating the wear caused by the bottom wall of the inner liner.

[0010] In some possible implementations, the bottom of the box body is provided with a first connecting part, and the side of the first connecting part facing away from the box body is provided with a mounting groove; the mounting structure includes a second connecting part and a contact part, the second connecting part is inserted into the mounting groove; the contact part is connected to the side of the second connecting part facing away from the first connecting part, and the side of the contact part facing away from the second connecting part has the contact surface.

[0011] With this configuration, the mounting slot is used for partial insertion of the mounting structure, and the slot wall can position the mounting structure, thereby improving the positional accuracy of the mounting structure.

[0012] Furthermore, during the assembly of refrigerator drawers, the second connecting part can be inserted into the mounting groove, and the groove wall can position the second connecting part. Compared with related technologies where the second connecting part and the first connecting part are connected by connecting bolts or other connectors, there is no need to manually adjust the relative position between the first and second connecting parts for positioning, which improves the convenience of assembling refrigerator drawers and thus increases the production efficiency of refrigerator drawers.

[0013] In some possible implementations, a guide slope is provided on the circumferential edge of the end of the second connecting portion facing away from the contact portion; the guide slope is inclined toward the vertical centerline of the contact portion in the direction from the contact portion toward the second connecting portion.

[0014] With this design, the guide ramp can guide the second connecting part, making it easier to install the second connecting part into the mounting groove of the box, thereby improving the assembly efficiency of the refrigerator drawer and the production efficiency of the refrigerator drawer.

[0015] In some possible implementations, the second connecting portion has at least one connecting rib on the side adjacent to the contact portion, the connecting rib being arranged vertically and abutting against the wall of the mounting groove.

[0016] With this design, the gap between the second connecting part and the groove wall of the mounting groove can be adjusted by adjusting the thickness of the connecting ribs during the assembly of the refrigerator drawer, thereby improving the assembly reliability of the refrigerator drawer.

[0017] In some possible implementations, a connecting through hole is provided on one side wall of the mounting groove; a first connecting protrusion is provided on the side of the second connecting part, and the first connecting protrusion is engaged in the connecting through hole.

[0018] With this design, during the assembly of refrigerator drawers, the first connecting protrusion can be engaged in the connecting through hole to connect the second connector to the wall of the mounting slot. This eliminates the need for additional connectors, reduces the number of parts in the refrigerator drawers, and improves the ease of assembly, thereby increasing the production efficiency of refrigerator drawers and reducing production costs.

[0019] In some possible implementations, the second connecting part is provided with a first clearance groove on the side facing the first connecting part, and the first clearance groove is provided with two second clearance grooves on the groove wall facing the connecting through hole, and the two second clearance grooves are respectively located on both sides of the first connecting protrusion.

[0020] With this design, the first and second clearance grooves can separate the first connecting protrusion from the other parts of the second connecting part, making the first connecting protrusion more easily deformed under external force. This facilitates the first connecting protrusion being snapped into the connecting cylinder hole, improving the convenience of assembling and installing the structure and the box, thereby increasing the production efficiency of refrigerator drawers.

[0021] In some possible implementations, the mounting structure further includes a shielding portion, which is opposite to the sidewall of the second connecting portion where the first connecting protrusion is provided, and the shielding portion and the second connecting portion are respectively located on both sides of the sidewall of the first connecting portion where the connecting through hole is provided.

[0022] This design allows the shielding part to cover the connecting cylinder hole and the first buckle, improving the aesthetics of the refrigerator drawer.

[0023] In some possible implementations, the shielding portion has a second connecting protrusion on the side facing the second connecting portion, and the second connecting protrusion is engaged in the connecting through hole.

[0024] With this configuration, the second connecting part is connected to the groove wall of the mounting groove by both the first connecting protrusion and the second connecting protrusion snapped into the connecting through hole, which improves the connection strength between the second connecting part and the groove wall of the mounting groove, thereby making the connection between the mounting structure and the box body more secure.

[0025] A second aspect of this application provides a refrigerator, including a cabinet and a refrigerator drawer as described in any of the preceding claims, the refrigerator drawer being located within the inner liner of the cabinet.

[0026] The refrigerator of this application embodiment includes the refrigerator drawer described in any of the above claims, and therefore also has the advantages of the refrigerator drawer described in any of the above claims. For details, please refer to the relevant description above, which will not be repeated here. Attached Figure Description

[0063] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0064] Regarding the technical problem in related technologies where refrigerator drawers cause wear and grooves on the bottom wall of the inner liner during the sliding process, affecting the refrigerator's appearance and leading to the accumulation of dust and impurities in the grooves, thus hindering cleanliness, the inventors have discovered that the cause lies in the following: The bottom of the drawer has multiple support ribs extending along the sliding direction. During the sliding process, these support ribs and the bottom wall of the inner liner form a contact line parallel to the sliding direction. When the drawer moves, this contact line remains, and the friction concentrates on it, causing wear and grooves on the bottom wall of the inner liner, affecting the refrigerator's appearance and leading to the accumulation of dust and impurities in the grooves, making them difficult to remove and hindering cleanliness.

[0065] In view of this, this application provides a refrigerator drawer, which, by providing a mounting structure at the bottom of the drawer body, forms at least one contact line perpendicular to the pushing and pulling direction of the refrigerator drawer with the bottom wall of the inner liner. When the refrigerator drawer is pushed or pulled, the contact line between the mounting structure and the bottom wall of the inner liner forms a contact plane. Compared with the related technology where the refrigerator drawer and the bottom wall of the inner liner form a contact line parallel to the pushing and pulling direction, and the contact line between them remains during the pushing and pulling process, this application can disperse the motion friction generated between the drawer body and the bottom wall of the inner liner onto the contact plane formed between them, rather than concentrating it on the contact line, thereby reducing or eliminating the wear generated on the bottom wall of the inner liner, ensuring the appearance of the refrigerator, and improving the ease of cleaning the refrigerator.

[0066] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0067] In the description of the embodiments of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the 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, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0068] In the description of the embodiments of this application, it should be understood that the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0069] Unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the connection within two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0070] Furthermore, the terms “first”, “second”, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0071] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The first aspect of this application provides a refrigerator drawer located within the inner liner of a refrigerator body. The refrigerator drawer includes a box body 100 and a mounting structure 200 connected to the bottom of the box body 100. The mounting structure 200 has a contact surface 210 facing the bottom wall 300 of the inner liner. The contact surface 210 contacts the bottom wall 300 to form at least one contact line L. The extending direction of the contact line L is perpendicular to the pushing / pulling direction of the refrigerator drawer. It should be noted that the pushing / pulling direction refers to the direction of movement of the refrigerator drawer within the inner liner. For example... Figure 1 and Figure 3 The direction x is shown.

[0072] The refrigerator drawer of this embodiment features a mounting structure 200 located below the drawer body 100. The mounting structure 200 and the bottom wall 300 of the inner liner form at least one contact line L perpendicular to the push-pull direction of the refrigerator drawer. (See reference...) Figure 3 and Figure 4 When the refrigerator drawer is in the first position, its outline is represented by a dashed line; when the refrigerator drawer is in the second position, its outline is represented by a dashed line. When the refrigerator drawer is pushed or pulled, that is, when the refrigerator drawer slides between the first and second positions, the contact line L between the mounting structure 200 and the bottom wall 300 of the inner liner forms a contact plane S.

[0073] Compared with the related technology in which the refrigerator drawer and the bottom wall 300 of the inner liner form a contact line parallel to the pushing and pulling direction, and the contact line between them remains during the pushing and pulling process, the embodiment of this application, while ensuring that the refrigerator drawer can slide smoothly in the inner liner, disperses the motion friction generated between the refrigerator drawer and the bottom wall 300 of the inner liner onto the contact plane S formed between the mounting structure 200 and the bottom wall 300 of the inner liner, rather than concentrating it on the contact line. This reduces or eliminates the wear generated on the bottom wall 300 of the inner liner, ensures the appearance of the refrigerator, improves the ease of cleaning, and thus improves the quality and reliability of the product.

[0074] refer to Figure 15 and Figure 16 The image shows the test results obtained from a 20,000-cycle push-pull test of a refrigerator drawer in a related technology. Figure 15 and Figure 16 In the image, it is clearly visible that the area marked by the center circle on the bottom wall of the inner liner is worn, and the wear is quite severe. (Reference) Figure 17 and Figure 18 The image shows the test results obtained from a 20,000-cycle push-pull test of a refrigerator drawer according to an embodiment of this application. From... Figure 17 and Figure 18 It is clearly visible that there is no wear identifiable to the naked eye on the bottom wall of the inner liner. Therefore, the refrigerator drawer of this embodiment can reduce or eliminate wear on the bottom wall 300 of the inner liner.

[0075] It should be noted that "the mounting structure 200 forming at least one contact line L with the bottom wall 300 of the inner liner" means that there can be one or more contact lines L between the mounting structure 200 and the bottom wall 300 of the inner liner. The more contact lines L there are, the less wear and tear on the bottom wall 300 of the inner liner. The fewer contact lines L there are, the smoother the refrigerator drawer slides within the inner liner. The number of contact lines L can be adjusted according to specific circumstances to achieve a balance between wear on the bottom wall 300 of the inner liner and the smoothness of the refrigerator drawer's movement.

[0076] The technical solution of this application embodiment is described below using the number of contact lines L as an example.

[0077] For example, refer to Figure 5 , Figure 6 and Figure 7 The box body 100 can be a box structure with a top opening, through which items can be taken out and placed. In some possible implementations of this application embodiment, a cover plate can be provided over the top opening, and the cover plate can open or close the top opening. When the cover plate is open, items can be taken out or placed from the box body 100. When the cover plate is closed, a closed space can be formed inside the box body 100 to reduce cold leakage. Alternatively, the cover plate can also seal the top opening, forming a sealed space inside the box body 100 to enhance the preservation effect of the items.

[0078] An installation structure 200 may be provided on the side of the box body 100 facing the bottom wall 300 of the inner liner.

[0079] In some possible implementations of the embodiments of this application, the box body 100 and the mounting structure 200 can be integrally formed. For example, the box body 100 and the mounting structure 200 can be integrally formed by injection molding, stamping, or other methods. This configuration can reduce the processing and assembly difficulty of the box body 100 and the mounting structure 200, improve the production efficiency of refrigerator drawers, and also improve the connection strength between the box body 100 and the mounting structure 200, preventing the box body 100 and the mounting structure 200 from separating from each other, thereby improving the structural reliability of the refrigerator drawer.

[0080] For example, the materials of the housing 100 and the mounting structure 200 can both be polystyrene (PS), polypropylene (PP), or other materials, which will not be elaborated in the embodiments of this application.

[0081] In some other possible implementations of the embodiments of this application, reference is made to Figure 4 The box body 100 and the mounting structure 200 can also be set separately. With this setting, during the assembly of the refrigerator drawer, the structure and size of the mounting structure 200 can be adjusted separately without adjusting the entire refrigerator drawer, which improves the convenience of assembling and adjusting the refrigerator drawer.

[0082] For example, refer to Figure 6 , Figure 7 , Figure 8 , Figure 9The bottom of the housing 100 may be provided with a first connecting part 110, and the side of the first connecting part 110 facing away from the housing 100 is provided with a mounting groove 111, which is used for partial insertion of the mounting structure 200. The groove wall of the mounting groove 111 can position the mounting structure 200, thereby improving the positional accuracy of the mounting structure 200.

[0083] For example, refer to Figure 7 and Figure 9 The bottom of the box body 100 can also be provided with multiple reinforcing ribs 120. These ribs 120 can increase the strength of the box body 100 itself, thereby preventing breakage and improving the structural reliability of the refrigerator drawer. In the direction perpendicular to the bottom wall 300 of the inner liner, for example... Figure 9 In the direction y shown, the lowest point of the reinforcing rib 120 is at a first distance H1 with the bottom surface of the box 100, and the lowest point of the contact surface 210 of the mounting structure 200 is at a second distance H2 with the bottom surface of the box 100. The second distance H2 is greater than the first distance H1 to prevent the reinforcing rib 120 from contacting the bottom wall 300 and scratching the bottom wall 300 when the contact surface 210 slides on the bottom wall 300 of the inner liner.

[0084] The bottom of the housing 100 is provided with a mounting structure 200, which has a contact surface 210. A contact line L perpendicular to the pushing / pull direction is formed between the contact surface 210 and the bottom wall 300 of the inner liner. For example, refer to... Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 The mounting structure 200 may include a second connecting portion 220 and a contact portion 230. The second connecting portion 220 is inserted into the mounting groove 111. The contact portion 230 is connected to the side of the second connecting portion 220 facing away from the first connecting portion 110, and the side of the contact portion 230 facing away from the second connecting portion 220 has a contact surface 210. During the assembly of the refrigerator drawer, the second connecting portion 220 can be inserted into the mounting groove 111, and the groove wall of the mounting groove 111 can position the second connecting portion 220. Compared with the related art where the second connecting portion 220 and the first connecting portion 110 are connected by connecting bolts or other connecting parts, there is no need to manually adjust the relative position between the first connecting portion 110 and the second connecting portion 220 for positioning, which improves the convenience of assembling the refrigerator drawer and thus improves the production efficiency of the refrigerator drawer.

[0085] For example, refer to Figure 13The contact surface 210 can be at least one arcuate surface facing away from the bottom wall 300, with the axis of the arcuate surface perpendicular to the pushing and pulling direction of the refrigerator drawer. Since the contact surface 210 is an arcuate surface with its axis perpendicular to the pushing and pulling direction of the refrigerator drawer, even when the refrigerator drawer is tilted during pushing and pulling, it can still ensure that the contact surface 210 and the bottom wall 300 of the inner liner always form a contact line perpendicular to the pushing and pulling direction of the refrigerator drawer, thereby reducing or eliminating wear on the bottom wall 300 of the inner liner. The contact surface 210 can also be a hyperboloid or other arcuate surface, which will not be described in detail in this embodiment.

[0086] refer to Figures 10 to 14 A guide slope 221 may be provided on the circumferential edge of the end of the second connecting portion 220 facing away from the contact portion 230. Along the direction from the contact portion 230 to the second connecting portion 220, the guide slope 221 is inclined towards the vertical centerline of the contact portion 230. The guide slope 221 guides the second connecting portion 220, making it easier to install the second connecting portion 220 into the mounting groove 111 of the housing 100, thereby improving the assembly efficiency and production efficiency of the refrigerator drawer.

[0087] At least one connecting rib 222 may be provided on the side adjacent to the contact portion 230 of the second connecting portion 220. The connecting rib 222 is arranged vertically and abuts against the groove wall of the mounting groove 111. During the assembly of the refrigerator drawer, the gap between the second connecting portion 220 and the groove wall of the mounting groove 111 can be adjusted by adjusting the thickness of the connecting rib 222, thereby improving the assembly reliability of the refrigerator drawer.

[0088] For example, one side wall of the mounting groove 111 may be provided with a connecting through hole 112. The side of the second connecting part 220 is provided with a first connecting protrusion 223, which engages within the connecting through hole 112. During the assembly of the refrigerator drawer, the first connecting protrusion 223 is engaged within the connecting through hole 112, thereby connecting the second connector to the wall of the mounting groove 111 without the need for additional connectors. This reduces the number of parts in the refrigerator drawer and improves the ease of assembly, thereby increasing the production efficiency of the refrigerator drawer and reducing production costs.

[0089] A first clearance groove 224 may be provided on the side of the second connecting portion 220 facing the first connecting portion 110. Two second clearance grooves 225 are provided on the groove wall of the first clearance groove 224 facing the connecting through hole 112, and the two second clearance grooves 225 are respectively located on both sides of the first connecting protrusion 223. The first clearance groove 224 and the second clearance groove 225 can separate the first connecting protrusion 223 from the other parts of the second connecting portion 220, making the first connecting protrusion 223 more easily deformed under external force, thereby facilitating the first connecting protrusion 223 to be snapped into the connecting cylinder hole, improving the convenience of assembling and installing the structure 200 and the box body 100, thereby improving the production efficiency of the refrigerator drawer.

[0090] For example, the mounting structure 200 may further include a shielding portion 240, which faces the side wall of the second connecting portion 220 where the first connecting protrusion 223 is provided. The shielding portion 240 and the second connecting portion 220 are respectively located on both sides of the side wall of the first connecting portion 110 where the connecting through hole 112 is provided. The shielding portion 240 can shield the connecting cylinder hole and the first buckle, improving the aesthetics of the refrigerator drawer.

[0091] A second connecting protrusion 241 may be provided on the side of the shielding portion 240 facing the second connecting portion 220, and the second connecting protrusion 241 is engaged in the connecting through hole 112. The second connecting portion 220 is simultaneously connected to the groove wall of the mounting groove 111 by the first connecting protrusion 223 and the second connecting protrusion 241 engaged in the connecting through hole 112, which improves the connection strength between the second connecting portion 220 and the groove wall of the mounting groove 111, thereby making the connection between the mounting structure 200 and the box 100 more secure.

[0092] For example, the material of the mounting structure 200 can be polyoxymethylene resin (POM). POM has good wear resistance and a certain degree of lubrication, which can further prevent wear on the bottom wall 300 of the inner liner.

[0093] A second aspect of this application provides a refrigerator, including a cabinet and a refrigerator drawer as described above, the refrigerator drawer being located within the inner liner of the cabinet.

[0094] The refrigerator of this application embodiment includes any of the refrigerator drawers mentioned above, and therefore also has the advantages of any of the refrigerator drawers mentioned above. For details, please refer to the relevant description above, which will not be repeated here.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
