Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, and in particular to a door assembly and a refrigerator. Background Art

[0002] When the capacity of the refrigerator becomes larger and larger, the size of the refrigerator will be too large, and its door will become narrow and long, which will make the refrigerator door more easily deformed. If the door is deformed, it will not only affect the consumer's aesthetic experience, but also make the refrigerator door not tightly closed due to the deformation of the refrigerator door, which will affect the freezing effect of the refrigerator. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, in a first aspect, the present invention proposes a door body assembly, comprising: a door frame; and reinforcing ribs provided on the door frame, the reinforcing ribs being used to support the door frame, and the reinforcing ribs being an integrated arrangement.

[0005] The door body assembly provided by the utility model is used for a refrigerator. Reinforcing ribs are installed on the door frame. The reinforcing ribs support the door frame so that the reinforcing ribs can limit deformation of the door frame.

[0006] The reinforcement ribs in this solution are an integrated structure—that is, they are continuous rather than discontinuous. The reinforcement ribs themselves have no breakpoints, thus eliminating support gaps. Designing the reinforcement ribs on the door assembly as an integrated form changes the force transmission path within the door assembly, increases the overall rigidity of the door assembly, and improves the deformation of the door assembly, thereby enhancing the appearance of the refrigerator, ensuring the refrigerator's airtightness, and strengthening the freezer's airtightness.

[0007] In addition, the door assembly according to the above technical solution provided by the present invention may also have the following additional technical features:

[0008] In some technical solutions, the reinforcing ribs are annular and distributed along the circumference of the door frame.

[0009] The reinforcement ribs in this solution are annular in structure. Since the reinforcement ribs are an integrated structure, they form a complete annular structure, thus providing stable support for the door frame. The reinforcement ribs are distributed along the circumference of the door frame, ensuring that the door frame is fully supported by the reinforcement ribs at all points along its circumference, thereby improving the support effect of the reinforcement ribs on the door frame and preventing deformation of the door frame.

[0010] In some technical solutions, the door body assembly further includes: a support portion connected to the reinforcing rib, and the support portion is used to support the reinforcing rib.

[0011] The ribs are provided with support portions to support the ribs and prevent deformation. Since the ribs are used to support the door frame, supporting the ribs with the support portions further enhances the structural stability of the ribs, allowing them to withstand greater deformation forces, thereby further enhancing their support for the door frame.

[0012] In some technical solutions, a portion of the reinforcing rib is bent to form the supporting portion; or the supporting portion is fixed to the reinforcing rib by bonding, welding or locking.

[0013] The support portion and the reinforcement rib may be an integrated structure, that is, a portion of the reinforcement rib is used as the support portion, so that the support portion is not easily separated from the main portion of the reinforcement rib.

[0014] After a portion of the reinforcement rib is bent, the bent portion can improve the structural stability of the reinforcement rib, making the reinforcement rib less likely to deform, which is beneficial to improving the supporting effect of the reinforcement rib on the door frame.

[0015] Alternatively, the support portion and the reinforcement rib may be separate structures, and after the support portion is fixed to the reinforcement rib, the support portion improves the structural stability of the reinforcement rib. The support portion can be fixed to the reinforcement rib by welding or bonding, or locked to the reinforcement rib using a locking member such as a screw or pin.

[0016] In some technical solutions, the door assembly further includes: a hinge connected to the door frame, and the support portion is located on one side of the hinge.

[0017] The door frame in the door body assembly is rotatably connected to the main structure of the refrigerator through a hinge. Therefore, the position of the door frame for connecting the hinge is the main stress point on the door frame, which makes the position of the door frame connected to the hinge more prone to deformation. The support part is set on one side of the hinge, so that the support part is set at a position adjacent to the hinge. The support part can structurally strengthen the position of the reinforcement rib close to the hinge, so that the reinforcement rib can effectively support the position of the door frame close to the hinge to avoid deformation of the door frame.

[0018] In some technical solutions, the door body assembly also includes: a limiting portion, which is provided on the reinforcement rib, and the limiting portion is located on the inner side wall of the annular reinforcement rib; a foam part, at least a portion of which is located in the annular area of the reinforcement rib, and a portion of the foam part is in contact with the limiting portion, and the limiting portion is used to limit the foam part from separating from the reinforcement rib.

[0019] During the foaming process of the door assembly, a portion of the foamed part is contained within the annular area enclosed by the reinforcing ribs. A retaining portion is provided on the inner annular wall of the reinforcing ribs. During the foaming process, the foamed part wraps around the retaining portion, meaning that a portion of the retaining portion is embedded within the foamed part. This retaining portion acts as a position limiter for the foamed part, enhancing the adhesion between the foamed part and the reinforcing ribs. This prevents the foamed part from loosening or falling off the reinforcing ribs, thus improving the foaming effect.

[0020] In some technical solutions, the limiting portion is inclined toward the door frame compared to the reinforcing rib; or the limiting portion is inclined away from the door frame compared to the reinforcing rib.

[0021] The limiting portion is inclined relative to the reinforcing rib, that is, an angle is formed between the limiting portion and the inner sidewall. This inclined limiting portion can improve the retaining effect on the foam element, thereby further enhancing the adhesion between the foam element and the reinforcing rib. The limiting portion can be inclined toward the door frame, or it can be inclined away from the door frame.

[0022] In some technical solutions, the limiting portion is located on one side of the hinge; or the limiting portion is distributed along the circumference of the reinforcing rib.

[0023] The limiting portion is arranged on the reinforcing rib, and the limiting portion can further enhance the structural stability of the reinforcing rib, so that the reinforcing rib can withstand a greater deformation force, thereby further improving the supporting effect of the reinforcing rib on the door frame.

[0024] The limiting part is set on one side of the hinge, so that the limiting part is set at a position adjacent to the hinge. The limiting part can further strengthen the structure of the position near the hinge in the reinforcing rib, so that the reinforcing rib can effectively support the position adjacent to the hinge in the door frame to prevent the door frame from deformation.

[0025] Of course, the limiting portion may also be arranged in the circumferential direction of the reinforcing rib, which can not only improve the limiting effect of the limiting portion on the foaming member, but also enhance the structural stability of the reinforcing rib.

[0026] In some technical solutions, the reinforcing rib includes at least one reinforcing segment; when there are multiple reinforcing segments, at least two reinforcing segments are connected end to end in sequence.

[0027] The reinforcement rib can be formed by bending a single sheet of plate, with the single sheet being a reinforcement section. Alternatively, the reinforcement rib can be formed by connecting multiple sheets in sequence to form an integrated structure.

[0028] In a second aspect, the present invention provides a refrigerator comprising the door assembly as in the first aspect.

[0029] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0042] Refer to the following Figures 1 to 7 The present invention describes a door assembly and a refrigerator according to some embodiments of the present invention.

[0043] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a door body assembly 100 is proposed, including: a door frame 110 and a reinforcing rib 120, the reinforcing rib 120 is arranged on the door frame 110, the reinforcing rib 120 is used to support the door frame 110, and the reinforcing rib 120 is an integrated arrangement.

[0044] The door assembly 100 provided in this embodiment is used for a refrigerator. A reinforcing rib 120 is installed on the door frame 110 . The reinforcing rib 120 supports the door frame 110 , so that the reinforcing rib 120 can limit deformation of the door frame 110 .

[0045] The reinforcement ribs 120 in this solution are an integrated structure, that is, the reinforcement ribs 120 are a continuous structure rather than a discontinuous structure. The structure of the reinforcement ribs 120 itself does not have any breakpoints, and thus does not have support gaps due to breakpoints. The reinforcement ribs 120 on the door assembly 100 are designed as an integrated form. This can change the force transmission path within the door assembly 100, and also increase the overall rigidity of the door assembly 100, thereby improving the deformation of the door assembly 100, making the appearance of the refrigerator more beautiful, ensuring the sealing of the refrigerator, and enhancing the freezing sealing.

[0046] The door assembly 100 in this embodiment is suitable for refrigerators with high load-bearing capacity and large size.

[0047] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the reinforcing rib 120 is annular, and the annular reinforcing rib 120 extends along the circumference of the door frame 110 ( Figure 1 The arrow at B in the figure points to the distribution.

[0048] The reinforcing ribs 120 in this embodiment are annular in structure. Since the reinforcing ribs 120 are an integrated structure, they form a complete annular structure, thereby stably supporting the door frame 110. The reinforcing ribs 120 are distributed along the circumference of the door frame 110, ensuring that the door frame 110 is fully supported by the reinforcing ribs 120 at all locations along the circumference. This improves the supporting effect of the reinforcing ribs 120 on the door frame 110 and prevents deformation of the door frame 110.

[0049] Combine Figure 3 and Figure 4 As shown, in some embodiments, the door assembly 100 further includes: a support portion 130 , the support portion 130 is connected to the reinforcement rib 120 , and the support portion 130 is used to support the reinforcement rib 120 .

[0050] A support portion 130 is provided on the reinforcing rib 120 to support the reinforcing rib 120 and prevent deformation of the reinforcing rib 120. Since the reinforcing rib 120 is used to support the door frame 110, the support portion 130 further improves the structural stability of the reinforcing rib 120, allowing the reinforcing rib 120 to withstand greater deformation forces, thereby further improving the supporting effect of the reinforcing rib 120 on the door frame 110.

[0051] In some embodiments, a portion of the reinforcing rib 120 is bent to form the supporting portion 130. Alternatively, the supporting portion 130 is fixed to the reinforcing rib 120 by bonding, welding, or locking.

[0052] The support portion 130 and the reinforcement rib 120 may be an integrated structure, that is, a portion of the reinforcement rib 120 serves as the support portion 130 , so that the support portion 130 is not easily separated from the main portion of the reinforcement rib 120 .

[0053] After a portion of the reinforcing rib 120 is bent, the bent portion can improve the structural stability of the reinforcing rib 120 , making the reinforcing rib 120 less likely to deform, which is beneficial to improving the supporting effect of the reinforcing rib 120 on the door frame 110 .

[0054] Alternatively, the support portion 130 and the reinforcing rib 120 may be separate structures. After the support portion 130 is fixed to the reinforcing rib 120, the support portion 130 improves the structural stability of the reinforcing rib 120. The support portion 130 may be fixed to the reinforcing rib 120 by welding or bonding, or may be locked to the reinforcing rib 120 using locking members such as screws and pins.

[0055] Combine Figure 3 and Figure 4 As shown, in some embodiments, the door assembly 100 further includes a hinge 140 , the hinge 140 is connected to the door frame 110 , and the support portion 130 is located on one side of the hinge 140 .

[0056] The door frame 110 in the door body assembly 100 is rotatably connected to the main structure of the refrigerator through the hinge 140. Therefore, the position of the door frame 110 for connecting the hinge 140 is the main force point on the door frame 110, which makes the position of the door frame 110 connected to the hinge 140 more prone to deformation. The support part 130 is set on one side of the hinge 140, so that the support part 130 is set at a position adjacent to the hinge 140. The support part 130 can structurally strengthen the position of the reinforcement rib 120 close to the hinge 140, so that the reinforcement rib 120 can effectively support the position of the door frame 110 close to the hinge 140, thereby avoiding deformation of the door frame 110.

[0057] Combine Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the door body assembly 100 further includes: a limiting portion 150 and a foam part 160, the limiting portion 150 is provided on the reinforcing rib 120, the limiting portion 150 is located on the inner side wall 121 of the annular reinforcing rib 120, at least a portion of the foam part 160 is located in the annular area of the reinforcing rib 120, a portion of the foam part 160 is in contact with the limiting portion 150, and the limiting portion 150 is used to limit the foam part 160 from separating from the reinforcing rib 120.

[0058] During the foaming process of the door assembly 100, a portion of the foamed member 160 is contained within the annular region enclosed by the reinforcing ribs 120. A limiting portion 150 is provided on the annular inner sidewall 121 of the reinforcing ribs 120. During the foaming process, the foamed member 160 is wrapped around the limiting portion 150, i.e., a portion of the limiting portion 150 is embedded within the foamed member 160. The limiting portion 150 limits the foamed member 160, thereby enhancing the adhesion between the foamed member 160 and the reinforcing ribs 120. This prevents the foamed member 160 from loosening or falling off from the reinforcing ribs 120, thereby improving the foaming effect.

[0059] In this embodiment, an integrated reinforcing rib 120 is used, and the installation point of the hinge 140 is strengthened by flipping the material inside, and a barb structure, namely a limiting portion 150, is provided thereon to enhance the adhesion between the reinforcing rib 120 and the foam, thereby improving the overall structural strength of the door assembly 100.

[0060] The solution in this embodiment is used to improve the overall strength and rigidity of the door assembly 100, so that the door assembly 100 is not easily twisted or warped during foaming and use, thereby making the appearance of the refrigerator more beautiful and enhancing the freezing sealing.

[0061] like Figure 4 As shown, in some embodiments, the limiting portion 150 is inclined toward the door frame 110 compared to the reinforcing rib 120. Alternatively, the limiting portion 150 is inclined away from the door frame 110 compared to the reinforcing rib 120.

[0062] The limiting portion 150 is inclined relative to the reinforcing rib 120, that is, an angle is formed between the limiting portion 150 and the inner sidewall 121. The inclined limiting portion 150 can improve the limiting effect on the foam member 160, thereby further enhancing the adhesion between the foam member 160 and the reinforcing rib 120. The limiting portion 150 can be inclined toward the door frame 110, or it can be inclined away from the door frame 110.

[0063] Combine Figure 3 and Figure 4 As shown, in some embodiments, the limiting portion 150 is located on one side of the hinge 140. Alternatively, the limiting portion 150 is located along the circumference of the reinforcing rib 120 ( Figure 1 The arrow at B in the figure points to the distribution.

[0064] The limiting portion 150 is arranged on the reinforcing rib 120 , and the limiting portion 150 can also further enhance the structural stability of the reinforcing rib 120 , so that the reinforcing rib 120 can withstand a greater deformation force, thereby further improving the supporting effect of the reinforcing rib 120 on the door frame 110 .

[0065] The limiting portion 150 is arranged on one side of the hinge 140 so that the limiting portion 150 is arranged at a position adjacent to the hinge 140. The limiting portion 150 can further strengthen the structure of the position of the reinforcing rib 120 close to the hinge 140, so that the reinforcing rib 120 can effectively support the position of the door frame 110 close to the hinge 140, thereby preventing the door frame 110 from deformation.

[0066] Of course, the limiting portion 150 may also be provided in the circumferential direction of the reinforcing rib 120 , which can not only improve the limiting effect of the limiting portion 150 on the foaming member 160 , but also enhance the structural stability of the reinforcing rib 120 .

[0067] Combine Figure 6 and Figure 7 As shown, in some embodiments, the reinforcing rib 120 includes at least one reinforcing segment 170. Wherein, when there are multiple reinforcing segments 170, at least two reinforcing segments 170 are connected end to end in sequence.

[0068] The reinforcing rib 120 can be formed by bending a sheet of plate, and one sheet of plate is one reinforcing section 170. Alternatively, the reinforcing rib 120 is an integrated structure formed by sequentially connecting a plurality of sheets.

[0069] The reinforcing rib 120 is located between the door frame 110 and the inner liner 180. It can be formed by bending a plate into an integral shape and then welded together by a weld ( Figure 6 and Figure 7 The dotted line represents a weld seam, or it can be formed by splicing four or more weld seams. Weak areas, particularly at the connection to the hinge 140, can be reinforced by thickening the flanges. These flanges have barbs in various shapes, such as semicircular, right-angled, or Z-shaped. This structure improves adhesion between the ribs 120 and the foam, enhancing the overall rigidity and strength of the door assembly 100.

[0070] The reinforcing rib 120 is located between the door frame 110 and the inner liner 180, and its interior is filled with foam material that expands.

[0071] The barb structure, i.e., the limiting portion 150, can be appropriately arranged around the reinforcing rib 120 and more appropriately arranged at the weak points of the structural strength.

[0072] In an embodiment of the present invention, a refrigerator is proposed, which includes a door assembly as in any of the above embodiments and can achieve the same technical effects, which will not be described in detail here.
