Description

Technical Field

[0001] This utility model relates to the technical field of refrigerators, and more particularly to the metal door of a refrigerator. Background Technology

[0002] A refrigerator is a household appliance that uses a refrigeration system to lower the internal temperature to preserve and store food. Its core consists of a compressor, evaporator, condenser, and other components that form a refrigeration cycle. This system can stably control the internal temperature below 0°C or within a specific low-temperature range, effectively inhibiting the growth of microorganisms and extending the shelf life of food. The metal door is a common structural form of refrigerator doors. The door is mainly made of metal and has advantages such as high strength, wear resistance, and easy cleaning.

[0003] In existing refrigerators, to avoid loosening and leakage of foam when the door cover and metal door shell are assembled after the door body is foamed, double-sided tape or sponge is generally used at the assembly point of the metal door shell and the door cover. The filling effect blocks the overflow path of the foam material, thereby enhancing the connection and sealing between the two.

[0004] However, this assembly method, which relies on double-sided tape or sponge, requires manual pre-operation. Affected by workers' operating techniques and production errors, the double-sided tape between the metal door shell and the door cover is prone to misalignment, and the sponge is prone to wrinkling, resulting in the failure of sealing the assembly gap. Ultimately, the door body will leak and loosen after foaming, which not only affects product quality but also causes a large amount of material to be scrapped. Utility Model Content

[0034] Example 1

[0035] Reference Figures 1 to 5 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0036] The refrigerator door unit 100 and the step assembly 200 are provided on the refrigerator door unit 100 and are used to block the flow of foaming material.

[0037] Anti-slip component 300 is installed on the refrigerator door unit 100 and is used to prevent the door from slipping off the handle when it is pulled out.

[0038] In use, the refrigerator door unit 100 and the step assembly 200 work together to effectively block the flow of foam material and use the adhesiveness of the foam material to bond the parts together. This avoids the problems of material leakage and loosening caused by wrinkles of double-sided tape or sponge in traditional assembly, reduces production scrap, and improves the tightness and stability of door assembly. At the same time, it eliminates the use of adhesive materials, simplifies the process and reduces costs. Meanwhile, the anti-slip component 300 increases hand friction when the door is pulled out, prevents slippage, improves operation safety and convenience, and enhances the user experience.

[0039] Example 2

[0040] Reference Figures 1 to 5 This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0041] The refrigerator door unit 100 includes a metal door shell 101, a door liner 102 is assembled and connected inside the metal door shell 101, a door seal 103 is assembled and connected on the door liner 102, and an upper door cover 104 and a lower door cover 105 are respectively assembled and connected on the metal door shell 101, and both the upper door cover 104 and the lower door cover 105 are assembled and connected to the door seal 103.

[0042] The metal door shell 101 is used as the base and is assembled in conjunction with the door liner 102, upper door cover 104, and lower door cover 105 to enhance the overall structural rigidity. The door seal 103 is linked to the door liner 102, upper door cover 104, and lower door cover 105 to enhance the sealing performance, reduce cold air leakage, improve structural stability and assembly efficiency, and ensure the durability of the door.

[0043] Specifically, the step assembly 200 includes two step portions 201, which are integrally formed on the upper door cover 104 and the lower door cover 105, respectively. Both step portions 201 are fitted to the assembly edge of the metal door shell 101 and together form a closed structure after assembly.

[0044] Both stepped sections 201 are integrally formed on the upper door cover 104 and the lower door cover 105, and fit together with the metal door shell 101 at the assembly edge to form a closed structure. This can effectively prevent the foam material from overflowing, avoid leakage, eliminate the need for traditional adhesive materials, simplify the assembly process, and enhance the structural stability of the integral forming, improve the tightness of the assembly between the upper door cover 104, the lower door cover 105 and the metal door shell 101, and reduce loosening.

[0045] Specifically, the anti-slip component 300 includes an inner arc groove 301, which is formed on the upper door cover 104. An anti-slip pad 302 is fixedly installed on one inner wall of the inner arc groove 301. The anti-slip pad 302 is provided with multiple protrusions, which are spaced apart along the extension direction of the inner arc groove 301.

[0046] When in use, the inner arc groove 301 conforms to the curvature of the hand, making it easy to apply force, while the anti-slip pad 302, together with the spaced protrusions on it, can significantly enhance the friction, effectively prevent the hand from slipping when pulling the door, improve the grip comfort and anti-slip effect, and make the door more convenient and stable to use.

[0047] Example 3

[0048] Reference Figures 3 to 5 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0049] The upper door cover 104, the lower door cover 105, the door liner 102, and the metal door shell 101 together form a foaming cavity 1011, and the foaming material is filled into the foaming cavity 1011.

[0050] By enclosing and forming the foam cavity 1011, the foam material is fully filled, which enhances the insulation of the door and allows the components to be more tightly connected, thus improving the structural stability.

[0051] Specifically, both stepped portions 201 protrude from the upper door cover 104 and the lower door cover 105, and face one side of the metal door shell 101.

[0052] The stepped portion 201 protrudes from the upper door cover 104 and the lower door cover 105 and faces the metal door shell 101, enhancing the fit with the metal door shell 101 and further strengthening the effect of preventing the foam material from overflowing.

[0053] Specifically, the edges of the two stepped sections 201 and the junctions between the stepped surfaces and the step differences are all chamfered.

[0054] The chamfered edges reduce assembly friction, prevent damage to the edges of components, and make the step portion 201 fit more smoothly with the metal door shell 101.

[0055] Specifically, the door liner 102 has two positioning slots 1021, and the door seal 103 has two positioning heads 1022, both of which are assembled and connected to the corresponding positioning slots 1021.

[0056] When in use, the positioning groove 1021 is adapted to the positioning head 1022 to accurately position the door seal 103, prevent it from shifting or loosening, enhance the sealing performance, and reduce the leakage of cold air.

[0057] During use, the door insert 102 is first assembled and connected to the inside of the metal door shell 101 to form the basic frame of the door. Then, the upper door cover 104 and lower door cover 105 are assembled to the upper and lower parts of the metal door shell 101, respectively. At this time, the two integrally formed stepped portions 201 on the upper door cover 104 and lower door cover 105 precisely fit with the assembly edge of the metal door shell 101, forming a closed structure. Next, the door seal 103 is installed. The door seal 103 is assembled and connected to the two positioning grooves 1021 on the door insert 102 through its two positioning heads 1022, and simultaneously assembled with the upper door cover 104 and lower door cover 105 to ensure the sealing of the door edges. After assembly, the foaming stage begins, where the upper door cover 104, lower door cover 105, door insert 102, and metal door shell 101 together form a sealed enclosure. The foaming cavity 1011 is formed by combining the foaming material into the cavity. At this time, the two stepped parts 201 protrude from the side surface of the upper door cover 104 and the lower door cover 105 facing the metal door shell 101, which can effectively block the flow of the foaming material and prevent it from overflowing. The chamfer design of the edge of the stepped part 201 and the chamfer design at the junction of the stepped surface and the step difference can reduce assembly friction and ensure that the foaming material is evenly filled in the closed space, so that the upper door cover 104, the lower door cover 105 and the metal door shell 101 are tightly bonded by the foaming material. Finally, after the door body is formed, the inner arc groove 301 on the upper door cover 104 and the anti-slip pad 302 on the inner wall play their role. The multiple protrusions on the anti-slip pad 302, which are spaced apart along the extension direction of the inner arc groove 301, can enhance the hand friction when pulling the door body, prevent slipping, and improve the ease of use.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
