Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a drawer for a refrigerator, a method for manufacturing the same, and a refrigerator. Background Technology

[0002] To enhance user convenience, existing household appliances, such as refrigerators, typically include drawers in their storage compartments. Users can place items in these drawers and retrieve them by pulling them out. However, existing refrigerator drawers generally suffer from poor aesthetics.

[0003] When injection molding drawers, to ensure the mold core can easily detach from the drawer, the drawer's side walls typically have a draft angle, resulting in a slight tilt on the left and right side walls. When the drawer is placed inside a refrigerator, the gap between the drawer's side walls and the refrigerator's inner liner may not be constant in the vertical direction. This design affects the aesthetics when the user opens the refrigerator door and looks from the front. This problem is even more pronounced when the refrigerator has multiple drawers, where the bottom width of the upper drawer is inconsistent with the top width of the lower drawer.

[0004] Even if flanges are added to the left and right sides of the front wall of the drawer, and the outer edge of the flange is made vertical, making the gap between the outer edge of the drawer flange and the refrigerator liner uniform when viewed from the front, if the front wall of the drawer is transparent, the width of the flange will be uneven when viewed from the front because the projection of the side wall on the front is oblique. The distance between the junction of the drawer's side wall and front wall and the inner liner will vary along the height direction, thus still affecting the aesthetic value of the refrigerator.

[0005] Another type of drawer has a vertical outer surface for the side walls, while the inner surface is sloped along the vertical direction, meaning the wall thickness is uneven from top to bottom. While this design ensures a uniform gap between the drawer's side walls and the refrigerator's inner liner when viewed from the front, the uneven wall thickness—thinner at the top and thicker at the bottom—still affects the drawer's appearance and texture when the drawer is made transparent. Furthermore, this design is unsuitable for taller drawers because it would result in excessively thick side walls at the bottom.

[0006] In conclusion, existing refrigerator drawers suffer from poor aesthetics. Summary of the Invention

[0007] One object of the present invention is to provide an improved drawer for a refrigerator, a method of manufacturing the same, and a refrigerator.

[0008] One object of the present invention is to provide a refrigerator drawer that improves the appearance and texture, a method of manufacturing the same, and a refrigerator.

[0009] One embodiment of the present invention provides a drawer for a refrigerator, comprising: a bottom wall, a front wall, a rear wall, a pair of side walls, and an accommodating space enclosed by the bottom wall, the front wall, the rear wall, and the pair of side walls; the side walls include a first portion connected to the front wall, and a second portion connected to the first portion and located behind the first portion, the first portion and the second portion having different angles relative to the front wall and / or the bottom wall.

[0010] This implementation scheme improves the appearance and texture of the drawers, especially the aesthetic value of the drawer front, which in turn enhances the aesthetic appeal of the refrigerator's interior when the door is opened. For example, the first part, which has a greater impact on the appearance when viewed from the front, can be arranged to suit the front wall and / or surrounding environment, while the second part, which is less visible from the front, can be chosen to suit manufacturing considerations such as demolding.

[0011] For example, the sidewall includes two surfaces with a non-zero included angle, which can ensure that the mold core is provided with sufficient draft angle in different directions during demolding.

[0012] It should be understood that the angles of the first and second parts relative to the front and / or bottom walls may vary not only based on the demolding angle and direction.

[0013] Optionally, the first portion and the front wall form a first angle other than 90 degrees to provide a sufficient draft angle for the core used to form the front wall and side wall.

[0014] Optionally, the difference between the first included angle and 90 degrees is between 2 and 5 degrees to ensure that the draft angle of the first portion relative to the core used to form the front and side walls is greater than or equal to 1 degree.

[0015] Optionally, the spacing between the first portions of each of the pair of sidewalls gradually increases along the direction from the front wall to the rear wall, so as to form an outward expansion structure at the front of the drawer to increase the volume of the accommodating space.

[0016] Optionally, the second portion is perpendicular to the front wall to provide sufficient draft angle for the mold core used to form the side and rear walls.

[0017] Optionally, the intersection line of the inner surface of the first part and the front wall is perpendicular to the horizontal plane, and / or, the intersection line of the outer surface of the first part and the front wall is perpendicular to the horizontal plane. Thus, the first part has no slope along its height, making the intersection line of the side wall and the front wall vertical when viewed from the front of the drawer, visually without any tilt. In other words, the front of the drawer has a square structure, resulting in a high aesthetic appeal. Furthermore, when the intersection lines of both the inner and outer surfaces of the first part and the front wall are perpendicular to the horizontal plane, the wall thickness of the first part is uniform from top to bottom.

[0018] Optionally, the intersection of the inner surface of the second portion and the rear wall forms a second angle (not 90 degrees) with the horizontal plane, and / or, the intersection of the outer surface of the second portion and the rear wall forms a third angle (not 90 degrees) with the horizontal plane. Thus, the second portion has a slope along its height to provide sufficient draft angle for the mold core used to form the sidewalls and rear wall, and effectively connects with the first portion, which has no slope along its height but has a non-90-degree angle with the front wall. Furthermore, when the second angle equals the third angle, the wall thickness of the second portion is uniform from top to bottom.

[0019] Therefore, another aspect of the present invention provides a drawer for a refrigerator, comprising: a bottom wall, a front wall, a rear wall, and a pair of side walls, wherein the bottom wall, the front wall, the rear wall, and the pair of side walls enclose an accommodating space; the side walls include a first portion connected to the front wall and a second portion connected to the rear wall; wherein the first portion is perpendicular to the bottom wall but not perpendicular to the front wall; and the second portion is perpendicular to the front wall but not perpendicular to the bottom wall.

[0020] Because the first section is perpendicular to the bottom wall, it is advantageous to make it substantially parallel to the interior wall of the refrigerator, which is usually vertically extending, thus enhancing the overall quality of the refrigerator with this type of drawer. At the same time, by giving the first and second sections different relationships to the bottom and front walls, the manufacturing of the drawers is also easier while simultaneously improving the refrigerator's overall quality.

[0021] In some implementations, since the first part at the front is vertical, it is possible to present a generally regular rectangular structure to the user when viewed from the front of the drawer, even if the front wall of the drawer is transparent.

[0022] Optionally, the width of the first portion gradually decreases from top to bottom, where the width refers to the width of the first portion along the direction from the front wall to the rear wall. A smaller first portion helps reduce its impact on the volume of the accommodating space. Furthermore, the smaller the width of the first portion, the less of it protrudes from both sides of the front wall when viewed from the front of the drawer, and the closer the front of the drawer is to a regular quadrilateral.

[0023] Optionally, the lower end of the first part is connected to the bottom wall. That is, the second part is not directly connected to the front wall. This avoids affecting the aesthetics by having two non-zero angled surfaces of the side wall intersect with the front wall, and also ensures smooth demolding during manufacturing.

[0024] Optionally, the sidewall includes a receiving portion for accommodating the guide rail portion. The first portion includes a lower portion, the projection of which overlaps with the projection of the receiving portion in the direction from the front wall to the rear wall, and the lower portion is located in front of the receiving portion in the direction from the front wall to the rear wall. Thus, the lower portion of the first portion extends to the bottom wall to spatially separate the receiving portion from the front wall, making it possible for the intersection of the front wall and the sidewall to always be vertical.

[0025] Optionally, the receiving portion is connected to the second portion and the bottom wall respectively, and is recessed from the second portion toward the receiving space. The drawer is supported by the guide rail and is movably disposed in the refrigerator's storage compartment.

[0026] Optionally, there is a gap between the receiving portion and the first portion. That is, there is a second portion between the receiving portion and the first portion to make the overall structure simpler and more streamlined.

[0027] Optionally, the receiving portion extends to the first part along the direction from the rear wall to the front wall to extend the length of the receiving portion along the direction from the front wall to the rear wall, thereby increasing the travel distance of the drawer relative to the storage compartment.

[0028] Optionally, in the direction from the rear wall to the front wall, there is a gap between the receiving portion and the front wall, making it possible for the intersection line of the front wall and the side wall to always be vertical.

[0029] Optionally, the front wall includes side edges extending from one of the pair of side walls towards the other. The side edges extend beyond the junction of the outer surface of the first portion and the front wall, and the projections of the first and second portions onto the front wall do not exceed the outer contour of the side edges extending along the height direction of the drawer. Thus, the flanges on the left and right sides of the front wall can conceal irregular structures caused by different angles of the side walls, thereby enhancing the aesthetic value of the drawer's front.

[0030] Optionally, the intersection line of the first portion and the front wall is parallel to the outer contour of the side edge extending along the height direction of the drawer. Thus, from top to bottom, the distance between the outer contour of the side edge and the intersection line of the first portion and the front wall is equidistant, meaning the width of the flange is uniform from top to bottom. Furthermore, as the width of the first portion gradually decreases from top to bottom, the amount of the side wall protruding from the front wall is limited, allowing the flange width to be set correspondingly smaller.

[0031] Optionally, the front wall includes a lower edge that extends downward beyond the junction of the front wall and the bottom wall. By forming a flange at the lower end of the front wall, the bottom of the drawer is concealed by the flange when viewed from the front of the drawer.

[0032] Optionally, the lower edge connects to the side edges on both sides. This creates a continuous decorative band on the front of the drawer, enhancing its aesthetics. This advantage is even more pronounced when the front wall of the drawer is transparent, as a continuous outer ring can be formed on both sides and the bottom of the front wall, around the intersection lines formed by the side and bottom walls and the front wall, respectively. We found that this arrangement further enhances the drawer's appearance under lighting.

[0033] Optionally, the bottom wall includes a front section connected to the front wall, which gradually slopes upward along the direction from the rear wall to the front wall.

[0034] Optionally, the bottom wall includes a rear section located between the front and rear sections, with the lowest point of the lower edge flush with the lowest point of the rear section along the height direction of the drawer. Thus, the lower edge serves to conceal the bottom structure of the drawer, allowing the front of the drawer to potentially form a square shape formed by the outer contours of the lower and side edges, resulting in a more aesthetically pleasing appearance.

[0035] Optionally, the inner surface of the front section transitions to the front wall with an arc surface, and / or the outer surface of the front section transitions to the lower edge with an arc surface. Thus, curved transition strips are designed at the joints of the various parts, improving the drawer's aesthetic appearance based on the optical refraction principle of the arc-shaped portion.

[0036] Optionally, the bottom wall, front wall, rear wall, and a pair of side walls are integrally injection molded.

[0037] Optionally, the inner surface of the first part and the front wall transition with an arc surface; and / or, the outer surface of the first part and the front wall transition with an arc surface. Thus, a curved transition strip is designed at the joints of the parts, improving the drawer's aesthetic appearance based on the optical refraction principle of the arc-shaped portion.

[0038] Optionally, at least the front wall and the pair of side walls are transparent. When the drawer is placed in the refrigerator storage compartment, the user can see the stored items without pulling out the drawer.

[0039] Optionally, the drawer further includes a handle portion, which is disposed on the front wall, and both ends of the handle portion extend to be flush with the outer contours of the two sides of the front wall. The handle portion is designed to facilitate user gripping. Furthermore, when side edge portions are provided on both sides of the front wall, the two ends of the handle portion are flush with the outer contours of the side edge portions to ensure that the front of the drawer is a basically continuous and regular quadrilateral.

[0040] Therefore, in another aspect, the present invention provides a drawer for a refrigerator, comprising: a bottom wall, a front wall, a rear wall, a pair of side walls, and an accommodating space enclosed by the bottom wall, the front wall, the rear wall, and the pair of side walls; the intersection line of the side walls and the front wall is perpendicular to the horizontal plane; the intersection line of the side walls and the rear wall forms a non-90-degree angle with the horizontal plane.

[0041] Because the first section is perpendicular to the horizontal plane, it is advantageous to make it substantially parallel to the inner wall of the refrigerator, which is usually vertically extending, thus enhancing the overall quality of the refrigerator with this type of drawer. At the same time, by making the intersection lines of the side walls, front wall, and rear wall at different angles, it is beneficial to both enhance the quality of the refrigerator and facilitate the manufacture of the drawers.

[0042] Therefore, in another aspect, the present invention provides a refrigerator, comprising: a storage compartment; and at least one drawer as described above located within the storage compartment. The refrigerator with the aforementioned drawer has a more aesthetically pleasing overall appearance.

[0043] Optionally, the distance between the outer contours of the two sides of the front wall and the inner wall of the storage compartment is constant along the height direction of the drawer.

[0044] Optionally, the intersection line of the inner surface of the side wall and the front wall is parallel to the inner wall of the storage compartment, and / or, the intersection line of the outer surface of the side wall and the front wall is parallel to the inner wall of the storage compartment. Thus, the intersection line seen from the front is parallel to the inner wall, ensuring a visually uniform gap between the inner wall and the drawer. Furthermore, for drawers with a transparent front wall, the intersection line of the inner surfaces is also parallel to the inner wall, eliminating any unevenness in thickness when viewed from the front, thus improving the overall aesthetics.

[0045] Therefore, in another aspect, embodiments of the present invention provide a method for manufacturing any of the above-described drawers, comprising: injection molding a front wall, a bottom wall, a pair of side walls, and a rear wall of the drawer, wherein the front portion of the front wall and the front portion of the side walls are formed based on a first mold core, the front portion including a first part of the side walls; the rear wall of the drawer and the rear portion of the side walls are formed based on a second mold core, the rear portion including a second part of the side walls; the first mold core and the second mold core have different demolding directions. Since the side walls of any of the above-described drawers include two surfaces with a non-zero included angle, it is possible to provide sufficient draft angles for the respective demolding directions of the first mold core and the second mold core.

[0046] Optionally, the first mold core is demolded at an angle to both the front wall and the bottom wall, while the second mold core is demolded perpendicular to the bottom wall. That is, the demolding direction of the first mold core is different from that of the second mold core.

[0047] Optionally, corresponding portions of the bottom wall are formed based on the first mold core and the second mold core. That is, one portion of the bottom wall is formed by the first mold core, and another portion of the bottom wall is formed by the second mold core.

[0048] Optionally, the front portion includes a part of the second portion, and the rear portion includes another part of the second portion. That is, a part of the second portion is formed by a first mold core, and the other part of the second portion is formed by a second mold core. Attached Figure Description

Detailed Implementation

[0062] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0063] Figure 1 This is an overall schematic diagram of a refrigerator drawer according to an embodiment of the present invention; Figure 2 yes Figure 1 The drawer shown is a cross-sectional view along the AA direction; Figure 3 yes Figure 1 The front view of the drawer shown; Figure 4 yes Figure 1 The drawer shown is a cross-sectional view along the BB direction; Figure 5 yes Figure 1 The drawer shown is a cross-sectional view along the CC direction; Figure 6 yes Figure 1 A schematic diagram of the drawer along another direction; Figure 7 yes Figure 1 The drawer shown is a side view.

[0064] Specifically, refer to Figures 1 to 7 In this embodiment, drawer 1 may include a bottom wall 10a, a front wall 10b, a rear wall 10c, a pair of side walls 10d, and an accommodating space 11 enclosed by the bottom wall 10a, the front wall 10b, the rear wall 10c, and the pair of side walls 10d.

[0065] For ease of description, in this embodiment, the width direction of drawer 1 is denoted as the x-direction, the depth direction of drawer 1 as the y-direction, and the height direction of drawer 1 as the z-direction. The y-direction can be the direction from the front wall 10b of drawer 1 to the rear wall 10c, and the x-direction can be the direction from one of the pair of side walls 10d to the other.

[0066] In a specific implementation, continue to refer to Figures 1 to 7 For either of a pair of sidewalls 10d, the sidewall 10d may include a first portion 101 and a second portion 102, wherein the first portion 101 is connected to the front wall 10b, and the second portion 102 is connected to the first portion 101 and located behind the first portion 101. Specifically, "behind the first portion 101" refers to the rear direction along the y-direction shown in the figure. That is, along the y-direction, the second portion 102 is located between the first portion 101 and the rear wall 10c and is connected to both the first portion 101 and the rear wall 10c.

[0067] In one specific implementation, the first part 101 and the second part 102 may have different angles relative to the front wall 10b. That is, when the front wall 10b is parallel to the rear wall 10c, the angle formed between the first part 101 and the front wall 10b is different from the angle formed between the second part 102 and the rear wall 10c.

[0068] In one specific implementation, the first part 101 and the second part 102 may have different angles relative to the bottom wall 10a. That is, the angle formed by the first part 101 and the bottom wall 10a is different from the angle formed by the second part 102 and the bottom wall 10a.

[0069] In one specific implementation, the first part 101 and the second part 102 have different angles relative to the front wall 10b, and the first part 101 and the second part 102 also have different angles relative to the bottom wall 10a.

[0070] This implementation scheme is beneficial to improving the appearance and texture of drawer 1, especially enhancing the aesthetic value of the front of drawer 1, which in turn benefits refrigerators with drawer 1 (such as...). Figure 9 The aesthetics of the refrigerator interior front after opening the door (as shown in refrigerator 2) can be considered. For example, the first part 101, which has a greater impact on the appearance when viewed from the front, can be arranged to suit the front wall 10b and / or the surrounding environment, while the second part 102, which is not easily observed from the front, can be chosen to suit manufacturing considerations such as demolding.

[0071] For example, the sidewall 10d includes two surfaces with a non-zero included angle, which can ensure that the mold core is provided with sufficient draft angle in different directions during demolding.

[0072] It should be understood that the difference between the angle of the first part 101 relative to the front wall 10b and the angle of the second part 102 relative to the front wall 10b, and / or the difference between the angle of the first part 101 relative to the bottom wall 10a and the angle of the second part 102 relative to the bottom wall 10a, may not be limited to differences caused by demolding angle and direction.

[0073] Specifically, the inner surface 112 of the sidewall 10d includes two surfaces with a non-zero included angle, namely the inner surface 101a of the first portion 101 and the inner surface 102a of the second portion 102, as shown below. Figure 1 As shown. Correspondingly, the outer surface 113 of the sidewall 10d also includes two surfaces with a non-zero included angle, namely the outer surface 101b of the first portion 101 and the outer surface 102b of the second portion 102, as shown. Figure 4 As shown.

[0074] In a specific implementation, refer to Figure 1 , Figure 2 and Figure 4 The first part 101 and the front wall 10b can form a first included angle α that is not 90 degrees, so as to provide a sufficient draft angle for the core used to form the front wall 10b and the side wall 10d. That is, the first part 101 has a slope along the y direction.

[0075] For example, the difference between the first included angle α and 90 degrees can be between 2 and 5 degrees to ensure that the draft angle of the first part 101 relative to the core used to form the front wall 10b and the side wall 10d is greater than or equal to 1 degree.

[0076] In a specific implementation, refer to Figure 1 , Figure 2 and Figure 4 Along the direction from the front wall 10b to the rear wall 10c (i.e., along the y direction shown in the figure), the distance L1 between the first portions 101 of each of the pair of side walls 10d gradually increases to form an outward expansion structure at the front of the drawer 1 to increase the volume of the accommodating space 11.

[0077] In other words, the first part 101 of each of the pair of sidewalls 10d extends along the y direction from the connection point with the front wall 10b while tilting away from each other.

[0078] In a specific implementation, refer to Figure 1 , Figure 2 and Figure 6 The intersection line x1 of the inner surface 101a of the first part 101 and the front wall 10b is perpendicular to the horizontal plane. That is, the intersection line x1 is parallel to the z-direction. In other words, the inner surface 101a of the first part 101 has no slope along the z-direction.

[0079] In a specific implementation, refer to Figure 1 , Figure 2 and Figure 6 The intersection line x2 of the outer surface 101b of the first part 101 and the front wall 10b is perpendicular to the horizontal plane. That is, the intersection line x2 is parallel to the z-direction. In other words, the outer surface 101b of the first part 101 has no slope along the z-direction.

[0080] In one specific implementation, the intersection line x1 of the inner surface 101a of the first part 101 and the front wall 10b is perpendicular to the horizontal plane, and the intersection line x2 of the outer surface 101b of the first part 101 and the front wall 10b is also perpendicular to the horizontal plane.

[0081] Therefore, the first part 101 has no slope along the height direction (the z direction in the diagram), making the intersection line of the side wall 10d and the front wall 10b when viewed from the front of drawer 1 vertical, without any visual tilt, as shown. Figure 3 As shown. In other words, the front of drawer 1 has a square structure, which is aesthetically pleasing. Furthermore, when the intersection lines of the inner surface 101a and the outer surface 101b of the first part 101 with the front wall 10b are both perpendicular to the horizontal plane, the wall thickness of the first part 101 is uniform from top to bottom (i.e., in the opposite direction of the z direction shown in the figure).

[0082] In a specific implementation, refer to Figure 4 The second part 102 is perpendicular to the front wall 10b to provide sufficient draft angle for the mold core used to form the side wall 10d and the rear wall 10c. When the front wall 10b is parallel to the rear wall 10c, the second part 102 is also perpendicular to the rear wall 10c. That is, the second part 102 has no slope in the y-direction.

[0083] In a specific implementation, refer to Figure 1 and Figure 5 The intersection line x3 of the inner surface 102a and the rear wall 10c of the second part 102 forms a second angle β with the horizontal plane that is not 90 degrees. That is, the inner surface 102a of the second part 102 has a slope along the z direction.

[0084] For example, the difference between the second included angle β and 90 degrees can be between 1 and 3 degrees to ensure that the draft angle of the second part 102 relative to the core used to form the rear wall 10c and the side wall 10d is greater than or equal to 1 degree.

[0085] In a specific implementation, refer to Figure 1 and Figure 5 The intersection line x4 of the outer surface 102b and the rear wall 10c of the second part 102 forms a third angle θ with the horizontal plane that is not 90 degrees. That is, the outer surface 102b of the second part 102 has an inclination along the z direction.

[0086] For example, the difference between the third included angle θ and 90 degrees can be between 1 and 3 degrees.

[0087] In one specific implementation, the intersection line x3 of the inner surface 102a and the rear wall 10c of the second part 102 forms a second included angle β with the horizontal plane that is not 90 degrees, and the intersection line x4 of the outer surface 102b and the rear wall 10c of the second part 102 forms a third included angle θ with the horizontal plane that is not 90 degrees.

[0088] For example, the difference between the second included angle β and 90 degrees and the difference between the third included angle θ and 90 degrees can both be between 1 and 3 degrees.

[0089] Furthermore, the second included angle β can be equal to the third included angle θ. Alternatively, the second included angle β may not be equal to the third included angle θ.

[0090] Thus, the second part 102 has a slope along the height direction (z direction) to provide sufficient draft angle for the mold core used to form the side wall 10d and the rear wall 10c, and is effectively connected to the first part 101, which has no slope along the height direction (z direction) but has a non-90-degree angle with the front wall 10b.

[0091] Furthermore, when the second included angle β is equal to the third included angle θ, the wall thickness of the second part 102 is uniform from top to bottom.

[0092] In one specific implementation, the wall thickness of the first part 101 can be equal to the wall thickness of the second part 102.

[0093] Furthermore, the wall thickness of the first part 101 can be constant from top to bottom.

[0094] Furthermore, the wall thickness of the second part 102 can be constant from top to bottom.

[0095] In a typical application scenario, for the side wall 10d of the drawer 1 described in this embodiment, its first part 101 is not perpendicular to the front wall 10b but is perpendicular to the bottom wall 10a, while the second part 102 is perpendicular to the front wall 10b but not perpendicular to the bottom wall 10a.

[0096] Since the first part 101 is perpendicular to the bottom wall 10a, this facilitates making it substantially parallel to the generally vertically extending inner wall of the refrigerator (e.g., Figure 9 and Figure 10 (As shown), this improves the overall quality of the refrigerator with drawer 1. At the same time, by making the first part 101 and the second part 102 have different relationships with the bottom wall 10a and the front wall 10b, it is beneficial to improve the overall quality of the refrigerator and also facilitates the manufacture of drawer 1.

[0097] The fact that the first part 101 and the second part 102 have different relationships with the bottom wall 10a and the front wall 10b means that the angle of the first part 101 relative to the bottom wall 10a is different from the angle of the second part 102 relative to the bottom wall 10a, and that the angle of the first part 101 relative to the front wall 10b is different from the angle of the second part 102 relative to the front wall 10b.

[0098] In one specific implementation, since the first part 101 located at the front is vertical, even though the front wall 10b of the drawer 1 is transparent, it is possible to present a basically regular rectangular structure to the user when viewed from the front of the drawer 1.

[0099] In a variation, the sidewall 10d may further include a third portion (not shown), which, along the y-direction, may be located between the first portion 101 and the second portion 102 to serve as a transition. In other words, the first portion 101 and the second portion 102 may not be directly connected.

[0100] Furthermore, the third part can be a plane. Alternatively, the third part can also be a curved surface.

[0101] In a specific implementation, refer to Figure 1 , Figure 6 and Figure 7 Along the direction from top to bottom (i.e., the opposite direction of the z direction in the figure), the width w of the first part 101 gradually decreases, wherein the width w refers to the width of the first part 101 along the direction from the front wall 10b to the rear wall 10c (i.e., the y direction in the figure).

[0102] The smaller the area of ​​the first part 101, the less impact it has on the volume of the accommodating space 11. Furthermore, the smaller the width w of the first part 101, the less the first part 101 extends from the front wall 10b along the x-direction when viewed from the front of the drawer 1, and the closer the front of the drawer 1 is to a regular rectangle.

[0103] In a specific implementation, continue to refer to Figure 6 and Figure 7 The lower end of the first part 101 is connected to the bottom wall 10a. That is, the second part 102 is not directly connected to the front wall 10b. This is to avoid the two surfaces of the side wall 10d with non-zero included angles intersecting with the front wall 10b, which would affect the aesthetics. On the other hand, it ensures smooth demolding during manufacturing.

[0104] In a specific implementation, refer to Figure 1 , Figure 6 and Figure 7 The sidewall 10d may include a means for accommodating the guide rail portion 13 (e.g. Figure 3The receiving portion 103 (shown) may include a lower portion 104 in its first part 101. The projections of the lower portion 104 and the receiving portion 103 onto the front wall 10b in the direction pointing from the rear wall 10c (y-direction in the diagram) overlap. The lower portion 104 is located in front of the receiving portion 103 in the direction pointing from the front wall 10b to the rear wall 10c (y-direction in the diagram). Thus, the lower portion 104 of the first part 101 extends to the bottom wall 10a to spatially separate the receiving portion 103 from the front wall 10b, making it possible for the intersection line of the front wall 10b and the side wall 10d to always be vertical.

[0105] In one embodiment, the receiving portion 103 may be connected to the second portion 102 and the bottom wall 10a respectively, and recessed from the second portion 102 toward the receiving space 11.

[0106] The recessed space formed by the recess of the receiving part 103 toward the receiving space 11 can be provided with a bracket 111. The bracket 111 can be used to fix the guide rail part 13. The drawer 1 is supported by the guide rail part 13 and can be movably placed in the refrigerator's storage compartment.

[0107] refer to Figure 3 Viewed from the front, the front wall 10b of drawer 1 is basically a regular rectangular structure. The guide rail 13 extends slightly from the front wall 10b on both sides along the x direction, so that there is a gap between the inner wall of the refrigerator on which drawer 1 is installed and the side wall 10d of drawer 1, so that drawer 1 can slide smoothly along the guide rail to be pulled out or pushed back into the refrigerator.

[0108] Further, refer to Figure 9 and Figure 10 Since drawer 1 presents a basically regular rectangular structure to the user when viewed from the front, the gap between the inner wall 21a of the refrigerator 2 with drawer 1 described in this embodiment and drawer 1 is constant when viewed from the front, which makes it possible to improve the aesthetics of the front of the refrigerator 2 when it is opened.

[0109] In a specific implementation, refer to Figure 6 There may be a gap between the receiving portion 103 and the first portion 101. That is, there is a second portion 102 between the receiving portion 103 and the first portion 101 to make the overall structure simpler and smoother. In practical applications, the specific width of the gap can be adjusted as needed.

[0110] In one variation, the receiving portion 103 can extend to the first portion 101 in the direction from the rear wall 10c to the front wall 10b (opposite to the y-direction in the illustration), thus eliminating the gap between the receiving portion 103 and the first portion 101. In this variation, a portion of the receiving portion 103 is located between the second portion 102 and the bottom wall 10a, and another portion of the receiving portion 103 is located between the first portion 101 and the bottom wall 10a. This extends the length of the receiving portion 103 in the direction from the front wall 10b to the rear wall 10c (y-direction in the illustration), increasing the travel distance of the drawer 1 relative to the storage compartment.

[0111] In one specific implementation, in the direction from the rear wall 10c to the front wall 10b (the opposite direction of the y direction in the figure), there is a gap between the receiving part 103 and the front wall 10b to ensure that the intersection line of the front wall 10b and the side wall 10d is always vertical.

[0112] That is, at least a portion of the first part 101 exists between the receiving part 103 and the front wall 10b.

[0113] For example, at least a portion of the first part 101 exists between the receiving part 103 and the front wall 10b.

[0114] For example, there is a first part 101 and a part of a second part 102 between the receiving part 103 and the front wall 10b.

[0115] In a specific implementation, refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The front wall 10b may include a side edge portion 106 extending in a direction from one of the pair of side walls 10d to the other (i.e., the x-direction in the figure). The side edge portion 106 extends beyond the junction of the outer surface 101b of the first portion 101 and the front wall 10b, and the projections of the first portion 101 and the second portion 102 onto the front wall 10b do not exceed the outer contour of the side edge portion 106 extending along the height direction of the drawer 1 (the z-direction in the figure). Thus, the flanges provided on the left and right sides of the front wall 10b along the x-direction can cover the portions of the side walls 10d that protrude from the front wall 10b, so that only the front wall 10b is visible when viewed from the front of the drawer 1.

[0116] Specifically, the angle between the first part 101 and the side edge 106 is less than 90 degrees, and the angle between the first part 101 and the main body of the front wall 10b is greater than 90 degrees.

[0117] In a specific implementation, refer to Figure 2The intersection lines of the first part 101 and the front wall 10b (such as intersection lines x1 and x2) are parallel to the outer contour of the side edge portion 106 extending along the height direction of the drawer 1 (the z direction in the figure). As a result, the distance between the outer contour of the side edge portion 106 and the intersection lines of the first part 101 and the front wall 10b is equidistant from top to bottom, that is, the width of the flange is uniform from top to bottom.

[0118] Furthermore, as the width w of the first portion 101 gradually decreases along the top-to-bottom direction, the amount by which the side wall 10d protrudes from the front wall 10b is limited, allowing the width of the flange (i.e., the side edge portion 106) to be set relatively small, which helps to improve the overall aesthetics of the drawer 1.

[0119] In a specific implementation, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The front wall 10b may include a lower edge portion 107 that extends downward beyond the junction of the front wall 10b and the bottom wall 10a. By forming a flange at the lower end of the front wall 10b, the bottom of the drawer 1 is concealed by the flange when viewed from the front of the drawer 1.

[0120] In a specific implementation, refer to Figure 1 and Figure 3 The lower edge 107 can connect to the side edge 106 on both sides along the x-direction. This creates a continuous decorative band on the front of the drawer 1, enhancing its aesthetic appeal. This advantage is even more pronounced when the front wall 10b of the drawer 1 is transparent. Specifically, a continuous outer ring can be formed on both sides (such as the side edge 106) and the bottom (such as the lower edge 107) of the front wall 10b of the drawer 1, around the intersection lines formed by the side wall 10d and bottom wall 10a with the front wall 10b, respectively. We found that this arrangement is more conducive to enhancing the aesthetics of the drawer 1 under lighting.

[0121] In a specific implementation, refer to Figure 6 and Figure 7 The bottom wall 10a may include a front section 108, which is connected to the front wall 10b and extends along the rear wall 10c in the direction of the front wall 10b (opposite to the y direction in the figure). The front section 108 gradually tilts upward (i.e. along the z direction).

[0122] In a specific implementation, continue to refer to Figure 6 and Figure 7 The bottom wall 10a may include a rear section 109 located between the front section 108 and the rear wall 10c. Along the height direction of drawer 1 (the z-direction in the diagram), the lowest point of the lower edge 107 is flush with the lowest point of the rear section 109, as shown... Figure 3 and Figure 7As shown, the lower edge 107 serves to conceal the bottom structure of the drawer 1, making it possible for the front of the drawer 1 to be a rectangle formed by the outer contours of the lower edge 107 and the side edge 106, resulting in a high aesthetic appeal.

[0123] In a specific implementation, refer to Figure 6 The front section 108 can be connected to the first part 101, the second part 102 and the receiving part 103 on both sides along the x direction, and the rear section 109 can be connected to the receiving part 103 on both sides along the x direction.

[0124] In one variation, when the receiving portion 103 extends to the first portion 101, the front section 108 is connected to the first portion 101 and the receiving portion 103 on both sides along the x-direction, and the rear section 109 can be connected to the receiving portion 103 on both sides along the x-direction.

[0125] In one variation, the bottom wall 10a can be a surface that extends from the rear wall 10c to the front wall 10b while slowly tilting in the z direction.

[0126] In a specific implementation, refer to Figure 6 The inner surface 108a of the front section 108 and the front wall 10b can be transitioned by an arc surface.

[0127] In a specific implementation, refer to Figure 6 and Figure 7 The outer surface 108b of the front section 108 and the lower edge 107 can be transitioned by a rounded surface.

[0128] In one specific implementation, the transition between the inner surface 108a and the front wall 10b of the front section 108, as well as the transition between the outer surface 108b and the lower edge 107 of the front section 108, can be a rounded surface.

[0129] Therefore, curved connecting strips are designed at the joints of each part to improve the aesthetic appearance of drawer 1 based on the optical refraction principle of the arc part.

[0130] In one specific implementation, the bottom wall 10a, front wall 10b, rear wall 10c, and a pair of side walls 10d can be integrally injection molded. That is, the drawer 1 is an integral drawer.

[0131] In one specific implementation, the inner surface 101a of the first part 101 and the front wall 10b may be transitioned by an arc surface.

[0132] In a specific implementation, refer to Figure 7 The outer surface 101b of the first part 101 and the front wall 10b can be transitioned by an arc surface.

[0133] In one specific implementation, the transition between the inner surface 101a and the front wall 10b of the first part 101, as well as between the outer surface 101b and the front wall 10b of the first part 101, can be a circular arc surface.

[0134] Therefore, curved connecting strips are designed at the joints of each part to improve the aesthetic appearance of drawer 1 based on the optical refraction principle of the arc part.

[0135] In one embodiment, at least the front wall 10b and a pair of side walls 10d may be transparent. When drawer 1 is placed in the refrigerator storage compartment, the user can see the stored items without pulling out drawer 1.

[0136] For example, drawer 1 can be entirely transparent.

[0137] In a specific implementation, refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 The drawer 1 may include a handle portion 12, which is disposed on the front wall 10b, and the two ends of the handle portion 12 extend along the x direction to be flush with the outer contours of the two sides of the front wall 10b.

[0138] That is, along the x-direction, both ends of the handle portion 12 are flush with the outer contour of the side edge portion 106.

[0139] The handle 12 is designed for easy gripping. Furthermore, when side edge portions 106 are provided on both sides of the front wall 10b, the two ends of the handle 12 are flush with the outer contour of the side edge portions 106, ensuring that the front of the drawer 1 is a basically continuous and regular rectangle, such as... Figure 3 As shown.

[0140] In one specific implementation, since the two ends of the handle portion 12 along the x-direction are flush with the outer contour of the side edge portion 106, the two ends of the handle portion 12 along the x-direction protrude from the outer surface 101b of the first portion 101. Accordingly, the two ends of the handle portion 12 along the x-direction and the outer surface 101b of the first portion 101 can be transitioned with an arc surface to improve the aesthetics of the drawer 1 side.

[0141] In a specific implementation, refer to Figures 1 to 7 The drawer 1 for the refrigerator described in this embodiment may include: a bottom wall 10a, a front wall 10b, a rear wall 10c, a pair of side walls 10d, and an accommodating space 11 enclosed by the bottom wall 10a, the front wall 10b, the rear wall 10c, and the pair of side walls 10d; the intersection line of the side wall 10d and the front wall 10b (such as intersection line x1 and intersection line x2) is perpendicular to the horizontal plane; the intersection line of the side wall 10d and the rear wall 10c (such as intersection line x3 and intersection line x4) forms a non-90-degree angle with the horizontal plane.

[0142] Since the first part 101 is perpendicular to the horizontal plane, it is advantageous to make it substantially parallel to the inner wall of the refrigerator, which is usually vertically extending, thereby improving the quality of the refrigerator with drawer 1. At the same time, by making the intersection lines of the side wall 10d, the front wall 10b, and the rear wall 10c at different angles, it is advantageous to improve the quality of the refrigerator while also facilitating the manufacture of drawer 1.

[0143] The intersection lines of the side wall 10d, the front wall 10b, and the rear wall 10c with different angles refer to the fact that the intersection line of the side wall 10d and the front wall 10b is not parallel to the intersection line of the side wall 10d and the rear wall 10c.

[0144] Furthermore, a non-90-degree angle is formed between the first part 101 and the front wall 10b.

[0145] Furthermore, the second part 102 is perpendicular to the front wall 10b.

[0146] In one specific implementation, the upper edges of the pair of side walls 10d and the rear wall 10c of drawer 1 can be bent away from the accommodating space 11 to form a flange, thereby providing reinforcement.

[0147] Further, refer to Figure 3 Viewed from the front of drawer 1, the flanges formed by the upper edges of the pair of side walls 10d can appropriately extend beyond the outer contour of the side edge portion 106 extending in the height direction.

[0148] In one variation, refer to Figure 8 The bottom wall 10a of drawer 1 may have a wave structure 110, which can serve as a reinforcement.

[0149] For example, wave structure 110 can be set in the rear section 109.

[0150] Figure 9 This is a schematic diagram of a refrigerator according to an embodiment of the present invention; Figure 10 yes Figure 9 A magnified view of a portion of region D in the middle. Among them, Figure 9 This is a front view of refrigerator 2 after it has been opened.

[0151] Specifically, the refrigerator 2 described in this embodiment may include a storage compartment 21. For example, the storage compartment 21 may be a freezer compartment, a refrigerator compartment, a variable temperature compartment, etc.

[0152] Furthermore, the refrigerator 2 may include at least one such as: located within the storage compartment 21 Figures 1 to 8 Drawer 1 is shown. Refrigerator 2 with drawer 1 has a more aesthetically pleasing overall appearance.

[0153] Specifically, refer to Figure 9 and Figure 10Along the height direction of drawer 1 (the z-direction in the diagram), the distance d between the outer contours of both sides of the front wall 10b along the x-direction and the inner wall 21a of the storage compartment 21 is constant.

[0154] For example, distance d refers to the distance between the outer contour of the side edge 106 and the inner wall 21a of the storage chamber 21.

[0155] In one specific implementation, the intersection line of the inner surface 112 of the side wall 10d and the front wall 10b (i.e., the intersection line x1 of the inner surface 101a of the first part 101 and the front wall 10b) is parallel to the inner wall 21a of the storage chamber 21.

[0156] In one specific implementation, the intersection line of the outer surface 113 of the side wall 10d and the front wall 10b (i.e., the intersection line x2 of the outer surface 101b of the first part 101 and the front wall 10b) is parallel to the inner wall 21a of the storage chamber 21.

[0157] In one specific implementation, the intersection line of the inner surface 112 of the side wall 10d and the front wall 10b (i.e., the intersection line x1 of the inner surface 101a of the first part 101 and the front wall 10b), and the intersection line of the outer surface 113 of the side wall 10d and the front wall 10b (i.e., the intersection line x2 of the outer surface 101b of the first part 101 and the front wall 10b) are both parallel to the inner wall 21a of the storage chamber 21.

[0158] Therefore, when the front wall 10b of drawer 1 is transparent, the intersection line x2 seen from the front of refrigerator 2 is parallel to the inner wall 21a, ensuring that the visual gap between the inner wall 21a and drawer 1 is uniform. Furthermore, the intersection line x1 of the inner surface 112 is also parallel to the inner wall 21a, so that the wall thickness of the side wall 10d of drawer 1 and the distance between drawer 1 and inner wall 21a are basically constant when viewed from the front, which helps to improve the overall aesthetics.

[0159] Figure 10 It is manufacturing Figure 1 The flowchart shows the method for drawer 1.

[0160] Specifically, refer to Figure 10 The method for manufacturing the drawer described in this embodiment may include step S101: injection molding the front wall, bottom wall, a pair of side walls and the rear wall of the drawer.

[0161] Further, step S101 may include step S1011, forming the front portion of the front wall and the side wall based on the first mold core, wherein the front portion includes the first part of the side wall;

[0162] Step S1012: The rear wall of the drawer and the rear portion of the side wall are formed based on the second mold core, the rear portion including the second part of the side wall.

[0163] The first mold core and the second mold core have different demolding directions. Since the pair of side walls 10d of drawer 1 each include two surfaces with a non-zero included angle, it is possible to provide sufficient draft angles for the respective demolding directions of the first mold core and the second mold core.

[0164] In a specific implementation, the first mold core can be an inclined top, and the second mold core can be a mold core.

[0165] In one specific implementation, the first mold core is demolded at an angle to both the front wall 10b and the bottom wall 10a, while the second mold core is demolded perpendicular to the bottom wall 10a. That is, the demolding direction of the first mold core is different from that of the second mold core. Specifically, the first mold core is demolded along the y and z directions, while the second mold core is demolded along the z direction.

[0166] In one specific implementation, corresponding portions of the bottom wall 10a are formed based on the first mold core and the second mold core. That is, a portion of the bottom wall 10a is formed by the first mold core, and another portion of the bottom wall 10a is formed by the second mold core. For example, the front section 108 and a portion of the rear section 109 of the bottom wall 10a are formed by the first mold core, and the remaining portion of the rear section 109 of the bottom wall 10a is formed by the second mold core.

[0167] In one specific implementation, the front portion may include a part of the second portion 102, and the rear portion may include another part of the second portion 102. That is, a part of the second portion 102 is formed by the first mold core, and the other part of the second portion 102 is formed by the second mold core.

[0168] Specifically, for each sidewall 10d, the first portion 101 and the second portion 102 of the sidewall 10d are not completely divided according to the boundary line between the first mold core and the second mold core. For example, the intersection line of the first portion 101 and the second portion 102 may be located in the middle of the first mold core.

[0169] In one specific implementation, the second part 102 has a slope along the z-direction to ensure that the draft angle of the second part 102 relative to the first mold core is greater than or equal to 1 degree, and the draft angle of the second part 102 relative to the second mold core is also greater than or equal to 1 degree.

[0170] Furthermore, the draft angle of the second part 102 relative to the first mold core is not equal to the draft angle of the second part 102 relative to the second mold core.

[0171] In one specific implementation, the first part 101 has no draft angle along the z direction but has a draft angle along the y direction to ensure that the draft angle of the first part 101 relative to the first mold core is greater than or equal to 1 degree.

[0172] In one specific implementation, drawer 1 is an integrated drawer, that is, the bottom wall 10a, the front wall 10b, the rear wall 10c, and a pair of side walls 10d are integrally formed.

[0173] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this disclosure, even when only a single embodiment is described with respect to a particular feature. The examples of features provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, one or more technical features of the dependent claims may be combined with technical features of the independent claims, and technical features from the respective independent claims may be combined in any suitable manner rather than solely by the specific combinations listed in the claims.

[0174] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
