Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and in particular to a door and a refrigerator. Background Technology

[0002] Currently, a notch is often made in the sheet metal door shell of refrigerators to secure the handle, with a bent edging formed at the edge of the notch. However, the edging formed after bending the notch often springs back, increasing the difficulty of installing the handle at the notch. Furthermore, because of this springback, existing handles do not allow for sufficient space for this springback, resulting in an excessively large gap between the handle portion and the edging, thus reducing the door's overall quality. Summary of the Invention

[0003] In view of the above problems, a door and refrigerator that overcomes or at least partially solves the above problems are proposed.

[0004] One object of the present invention is to simplify the installation of the door handle assembly and improve the quality of the door.

[0005] Another objective of this invention is to prevent deformation of the recessed portion of the fixing plate.

[0006] In particular, according to one aspect of the present invention, a door body is provided, comprising:

[0007] The door shell includes a front panel and a side panel extending from one side of the front panel, the side panel serving as a decorative panel on the side of the door body away from the pivot axis, and the side panel having a notch, the edge of the notch forming a rim that bends toward the interior of the door body;

[0008] A handle assembly is installed at the notch, having a fixing plate portion and a recessed portion that extends inward from the center of the fixing plate portion toward the interior of the door body. The fixing plate abuts against the end of the edging edge, and the edge of the recessed portion extends toward the side plate to form a fastening portion adapted to the notch. The outer peripheral wall of the fastening portion abuts against the edging edge portion.

[0009] The first angle formed between the outer peripheral wall of the fastening part and the plane where the side plate is located is greater than the second angle formed between the surrounding edge and the plane where the side plate is located.

[0010] Optionally, the difference between the first included angle and the second included angle is 0.5 to 1.5 degrees.

[0011] Optionally, the recess gradually expands outward from the bottom toward the side plate.

[0012] Optionally, the edge of the fixing plate near the front panel is bent inward toward the door body to form a bonding plate, which is then bonded and fixed to the front panel.

[0013] Optionally, a sealing layer is located between the fixing plate and the side plate; and / or between the bonding portion and the front panel.

[0014] Optionally, the notch is located on the side panel near the front panel.

[0015] Optionally, the perimeter is provided with a plurality of bendable fixing pieces, and the fixing plate is provided with limiting holes and receiving grooves adapted to each fixing piece. The fixing piece is located in the limiting hole, and after bending, the bent part is located in the receiving groove.

[0016] Optionally, each of the fixing pieces is evenly arranged on the perimeter.

[0017] Optionally, the plane containing the fixing plate is parallel to the plane containing the side plate.

[0018] According to another aspect of the present invention, a refrigerator is also provided, comprising:

[0019] The door body according to any one of the above-mentioned claims.

[0020] In the door body of this invention, the latch assembly has a fixing plate portion and a recessed portion that extends inward from the center of the fixing plate portion toward the interior of the door body. The edge of the recessed portion extends toward the side plate to form a fastening portion that matches the notch. The outer peripheral wall of the fastening portion abuts against the edge portion. This structure is ingenious. During the manufacturing process of this structure, the fastening portion can be tilted toward the direction of edge rebound, thereby providing sufficient space for the edge to rebound and making the installation of the latch assembly simpler. Furthermore, this structure can prevent the gap between the edge and the outer peripheral wall of the fastening portion from being too large or too small, improving the quality of the door body.

[0021] Furthermore, when a user places their hand into the recess to open the door, a force is exerted on the portion of the recess near the front panel, causing the edge of the fixing plate near the front panel to bend inward toward the door to form a bonding plate. By bonding and fixing the bonding plate to the front panel, the bonding plate can bear the force on the portion of the recess near the front panel, thereby reducing the possibility of deformation of the recess.

[0022] Furthermore, positioning the sealing layer between the fixed panel and the side panel; and / or between the bonding part and the front panel can prevent the foam material from overflowing from the gap between the door shell and the handle assembly, thereby improving the quality of the door.

[0023] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0036] Currently, a notch is often made in the sheet metal door shell of refrigerators to secure the handle, with a bent edging forming around the edge of the notch. However, this bent edging often springs back, increasing the difficulty of installing the handle at the notch. Furthermore, because of this springback, existing handles do not allow for sufficient space for this springback, resulting in uneven gaps between the handle portion and the edging, thus reducing the door's overall quality. (See also...) Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a door in the prior art. Figure 2 yes Figure 1 A schematic diagram of the cross-section of the central gate structure. Figure 3 yes Figure 2 A partially enlarged structural diagram of part A in the middle. Figure 4 yes Figure 2 A partially enlarged structural diagram of section B. The existing door body includes a front panel 103, a handle 102, a side panel 104, and a retaining edge 105. The retaining edge 105 can spring back in the direction indicated by the arrow. However, in the existing technology, the portion of the handle 102 that mates with the retaining edge 105 cannot be made into a structure that tilts in the direction of springback, resulting in an excessively large gap between the retaining edge 105 and the handle 102, affecting the quality of the door body.

Figures 5 to 10The door body 200 may include a door shell and a door handle assembly. The door shell may include a front panel 201 and a side panel 202 extending from one side of the front panel 201. The side panel 202 serves as a decorative panel on the side of the door body 200 away from the pivot axis, and a notch 203 is provided on the side panel 202, with the edge of the notch 203 forming a perimeter 206 that bends inward toward the inside of the door body 200. The door handle assembly is installed at the notch 203 and has a fixing plate portion 204 and a recessed portion 205 that is recessed inward toward the inside of the door body 200 from the center of the fixing plate portion 204. The fixing plate abuts against the end of the perimeter 206, and the edge of the recessed portion 205 extends toward the side panel 202 to form a fastening portion 207 that is adapted to the notch 203. The outer peripheral wall of the fastening portion 207 abuts against the perimeter 206. The first angle r formed by the outer peripheral wall of the fastening part 207 and the plane where the side plate 202 is located is greater than the second angle y formed by the perimeter edge 206 and the plane where the side plate 202 is located.

[0038] In this embodiment, the handle assembly can be made of plastic. The outer peripheral wall of the fastening part 207 abuts against the edge 206. Generally, this can be understood as the outer peripheral wall of the fastening part 207 abutting against the portion of the edge 206 near the side plate 202. The handle assembly has a fixing plate part 204 and a recessed part 205 extending inward from the center of the fixing plate part 204 toward the interior of the door body 200. The edge of the recessed part 205 extends toward the side plate 202 to form the fastening part 207 that fits the notch 203. The outer peripheral wall of the fastening part 207 abuts against the edge 206. This structure is ingenious. During the manufacturing process of this structure, the fastening part 207 can be tilted toward the direction of the edge 206's rebound, thereby providing sufficient space for the edge 206 to rebound, making the installation of the handle assembly simpler. Furthermore, this structure can prevent the gap between the edge 206 and the outer peripheral wall of the fastening part 207 from being too large, improving the quality of the door body 200.

[0039] In one embodiment of the present invention, the difference between the first included angle r and the second included angle y can be 0.5 to 1.5 degrees.

[0040] In this embodiment, the rebound angle range of the edge 206 is generally small. Setting the difference between the first included angle r and the second included angle y to 0.5 to 1.5 degrees allows sufficient space for the rebound of the edge 206 and also avoids excessive gaps between the outer peripheral wall of the fastening part 207 and the edge 206.

[0041] In one embodiment of the present invention, the recess 205 gradually expands outward from the bottom toward the side plate 202.

[0042] In this embodiment, when a user opens the door 200 using the pry tool assembly, they generally only need to place part of their hand into the recess 205. Therefore, by making the recess 205 gradually expand outward from the bottom toward the side panel 202, it is easier for the user's hand to enter the recess 205 and for the user's fingers to more easily touch the inner wall of the recess 205, thus making it easier to open the door 200.

[0043] In one embodiment of the present invention, the edge of the fixing plate portion 204 near the front panel 201 is bent inward toward the door body 200 to form a bonding plate portion 209. The bonding plate portion 209 is bonded and fixed to the front panel 201.

[0044] In this embodiment, when the user places their hand into the recess 205 to open the door, a force is exerted on the portion of the recess 205 near the front panel 201. Therefore, the edge of the fixing plate 204 on the side near the front panel 201 is bent inward toward the door body 200 to form a fitting plate 209. The fitting plate 209 is then attached and fixed to the front panel 201, which allows the fitting plate 209 to share the force on the portion of the recess 205 near the front panel 201, thereby reducing the possibility of deformation of the recess 205.

[0045] In one embodiment of the present invention, the door body 200 may further include a sealing layer 208. The sealing layer 208 is located between the fixing plate portion 204 and the side plate 202; and / or between the fitting portion and the front panel 201.

[0046] In this embodiment, the sealing layer 208 can be an adhesive-backed sealing sponge, or other types of sealing layers 208. Positioning the sealing layer 208 between the fixing plate portion 204 and the side plate 202; and / or between the bonding portion and the front panel 201, can prevent the foam material from overflowing from the gap between the door shell and the handle assembly, thereby improving the quality of the door body 200.

[0047] In one embodiment of the present invention, the notch 203 is located on the side panel 202 near the front panel 201.

[0048] In this embodiment, the notch 203 is located on the side panel 202 near the front panel 201, allowing the user to open the door 200 with minimal force. Furthermore, the notch 203's location on the side panel 202 near the front panel 201 makes it easier for the bonding plate portion 209 to adhere and be fixed to the front panel 201, thus facilitating the assembly of the door 200.

[0049] In one embodiment of the present invention, a plurality of bendable fixing pieces 210 are provided on the perimeter 206, and the fixing plate portion 204 is provided with limiting holes 211 and receiving grooves 212 adapted to each fixing piece 210. The fixing piece 210 is located in the limiting hole 211, and after bending, the bent part is located in the receiving groove 212. The fixing pieces 210 can be evenly arranged on the perimeter 206.

[0050] In this embodiment, the fixing piece 210 is located in the limiting hole 211, and after bending, the bent part is located in the receiving groove 212, which can fix the handle assembly to the door shell. Furthermore, the fixing pieces 210 are evenly distributed on the perimeter 206, which can make the handle assembly more stable after it is fixed.

[0051] In one embodiment of the present invention, the plane in which the fixing plate portion 204 is located is parallel to the plane in which the side plate 202 is located.

[0052] In this embodiment, the plane where the fixing plate 204 is located is parallel to the plane where the side plate 202 is located, which makes it easier for the sealing layer 208 to seal the gap between the fixing plate 204 and the side plate 202 and / or between the fitting part and the front panel 201, making the installation of the door 200 simpler.

[0053] See Figure 11 Based on the same concept, the present invention also provides a refrigerator 300. The refrigerator 300 may include a door 200 according to any of the above embodiments.

[0054] The above embodiments can be combined arbitrarily. Based on any one preferred embodiment or a combination of multiple preferred embodiments, the embodiments of the present invention can achieve the following beneficial effects:

[0055] The door handle assembly has a fixing plate portion 204 and a recessed portion 205 extending inward from the center of the fixing plate portion 204 toward the interior of the door body 200. The edge of the recessed portion 205 extends toward the side plate 202 to form a fastening portion 207 that fits with the notch 203. The outer peripheral wall of the fastening portion 207 abuts against the edge 206. This structure is ingenious. During the manufacturing process, the fastening portion 207 can be tilted toward the direction of the edge 206's rebound, thus providing sufficient space for the edge 206 to rebound, making the installation of the door handle assembly simpler. Furthermore, this structure can prevent the gap between the edge 206 and the outer peripheral wall of the fastening portion 207 from being too large or too small, improving the quality of the door body 200.

[0056] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
