Description

Technical Field

[0002] Traditional refrigerator doors feature a metal layer with magnetic properties, allowing users to attach refrigerator magnets, sticky notes, and other items to the door surface. In recent years, glass panels have become increasingly popular for refrigerator doors due to their superior appearance, texture, and corrosion resistance. To enable glass panels to also have magnetic properties, multiple layers of magnetic ink containing iron or magnetic powder are typically applied to the front of the glass panel.

[0003] To ensure sufficient magnetic attraction for the glass panel, multiple coats of magnetic ink are required to achieve a certain thickness. However, the high cost of magnetic ink increases the price of refrigerators, hindering large-scale production. Furthermore, the coating process for the magnetic ink layer is complex, resulting in a high defect rate and low yield, which also increases manufacturing costs. Summary of the Invention

[0018] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] Traditional refrigerator doors feature a metal layer with magnetic properties, allowing users to attach refrigerator magnets, sticky notes, and other items to the door surface. In recent years, glass panels have become increasingly popular for refrigerator doors due to their superior appearance, texture, and corrosion resistance. To enable glass panels to also have magnetic properties, multiple layers of magnetic ink containing iron or magnetic powder are typically applied to the front of the glass panel.

[0020] To ensure sufficient magnetic attraction for the glass panel, multiple coats of magnetic ink are required to achieve a certain thickness. However, the high cost of magnetic ink increases the price of refrigerators, hindering large-scale production. Furthermore, the coating process for the magnetic ink layer is complex, resulting in a high defect rate and low yield, which also increases manufacturing costs.

[0021] To address the aforementioned issues, this embodiment provides a refrigerator door and a refrigerator, wherein the refrigerator door uses a glass substrate as its main body and a magnetic metal plate is provided on the inner side of the glass substrate to give the refrigerator door magnetic attraction, allowing users to attach refrigerator magnets to the front of the refrigerator door.

[0022] Example 1.

[0023] The refrigerator provided in this embodiment includes a refrigerator compartment, a freezer compartment, and a variable-temperature compartment, arranged vertically. The refrigerator compartment has a refrigerator door, and the variable-temperature compartment can be located inside the refrigerator compartment, sharing a refrigerator door with it. Alternatively, the variable-temperature compartment has its own door. The freezer compartment has a freezer door, or the freezer compartment can be a drawer structure.

[0024] The refrigerator door, freezer door, and variable temperature compartment door can have various layouts, such as top and bottom arrangement, top, middle and bottom arrangement, and cross door. The technical solution provided in this embodiment can be used for all refrigerator doors.

[0025] This embodiment is only used as an example. Figure 1 Taking the refrigerator shown as an example, the refrigerator includes a main body 1 and refrigerator doors 2, which are specifically two double-opening refrigerator compartment doors. Below the refrigerator compartments is a freezer compartment, which is a drawer.

[0026] In the diagram, the X direction represents the width of the refrigerator, the Y direction represents the depth of the refrigerator, and the Z direction represents the height of the refrigerator.

[0027] like Figure 2 As shown, the refrigerator door 2 includes: a glass substrate 21, a varnish layer 22, an appearance pattern layer 23, and a magnetic metal plate 24.

[0028] The glass substrate 21 can be ordinary glass or tempered glass, and has a first surface and a second surface. The first surface is the surface located on the outside of the refrigerator after the refrigerator door 2 is installed in the refrigerator, that is, the first surface of the glass substrate 21 faces outward and the second surface faces inward.

[0029] The varnish layer 22 is disposed on the first surface of the glass substrate 21, for example, the varnish layer 22 can be formed on the first surface of the glass substrate 21 by screen printing process.

[0030] The appearance pattern layer 23 is disposed on the surface of the varnish layer 22, for example, the appearance pattern layer 23 can be formed on the surface of the varnish layer 22 by screen printing process.

[0031] A magnetic metal plate 24 is disposed on the second surface of the glass substrate 21. The magnetic metal plate 24 is made of a metal with magnetic attraction capabilities, such as an iron plate or a galvanized steel plate, and can attract permanent magnets by magnetic force. If an iron plate is used, rust prevention treatment can be carried out by means of plating or coating with anti-rust paint.

[0032] The technical solution provided in this embodiment uses a glass substrate for the refrigerator door. The glass substrate has a first surface and a second surface, with the first surface being the surface on the outside of the refrigerator after the door is installed. A varnish layer is disposed on the first surface of the glass substrate; an appearance pattern layer is disposed on the surface of the varnish layer; and a magnetic metal plate is disposed on the second surface of the glass substrate, which can magnetically attract permanent magnets, allowing users to attach refrigerator magnets, sticky notes, etc., to the refrigerator door. Furthermore, the cost of the magnetic metal plate is much lower than that of magnetic ink, which can reduce the price of the refrigerator. This solution can be applied to various refrigerator models, facilitating large-scale promotion. In addition, the manufacturing process using the magnetic metal plate is simpler, which can improve the yield rate, reduce manufacturing costs, and further reduce the price of the refrigerator.

[0033] Based on the above technical solution, the refrigerator door 2 also includes an inner liner 25 and a foam layer 26. The inner liner 25 is disposed on the surface of the magnetic metal plate 24, and the foam layer is formed between the magnetic metal plate 24 and the inner liner 25. The foam layer can firmly bond the magnetic metal plate 24, the inner liner 25, the glass substrate 21, and the door frame to form the door structure.

[0034] The thickness of the glass substrate 21 is 1.0mm-2.5mm, specifically one of 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, or 2.5mm, or it can be accurate to two decimal places.

[0035] The thickness of the magnetic metal plate 24 is 0.1mm-1mm, specifically one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm, or it can be accurate to two decimal places.

[0036] The combination of glass substrates 21 of varying thicknesses with magnetic metal plates 24 yielded a magnetic attraction force of 6.5N-11N, sufficient to attract everyday refrigerator magnets. A magnetic attraction force of 6.5N is sufficient to firmly attach a regular refrigerator magnet to the refrigerator.

[0037] One specific implementation scheme is as follows: a glass substrate 21 with a thickness of 1.0 mm is combined with a magnetic metal plate 24 with a thickness of 0.25 mm, and the magnetic attraction force can reach more than 6.5 N.

[0038] Another specific implementation scheme is to combine a 1.1mm thick glass substrate 21 with a 0.5mm thick magnetic metal plate 24, so that the magnetic attraction force can reach about 8.5N.

[0039] Another specific implementation scheme is as follows: a glass substrate 21 with a thickness of 1.1 mm is combined with a magnetic metal plate 24 with a thickness of 1.0 mm, and the magnetic attraction force can reach about 10.2 N.

[0040] In addition, the thickness of the varnish layer 22 is 5μm-80μm, specifically 5μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, ... 20μm, 21μm, ... 30μm, 31μm, ... 40μm, 41μm, ... 50μm, 51μm, ... 60μm, 61μm, ... 70μm, 71μm, ... 80μm, and can be accurate to one decimal place.

[0041] The thickness of the pattern layer 23 is typically 10μm-150μm, but can also be greater than 150μm. The specific thickness can be determined based on the pattern design and tactile feel.

[0042] Example 2.

[0043] Based on the above embodiments, this embodiment also provides a method for manufacturing a refrigerator door, used to manufacture the refrigerator door in Embodiment 1. The method includes the following steps: Step 1: A varnish layer 22 is formed on the first surface of the glass substrate 21 by screen printing.

[0044] Step 2: Form an appearance pattern layer 23 on the surface of the varnish layer 22 using a screen printing process.

[0045] Step 3: Install and fix the glass substrate 21 to the door frame to form a door shell assembly.

[0046] Step 4: Place the door shell assembly into the first mold, so that the first surface of the glass substrate 21 faces the inside of the first mold.

[0047] Step 5: Fix the magnetic metal plate 24 on the second surface of the glass substrate 21.

[0048] Step 6: Inject foam material onto the surface of the magnetic metal plate 24.

[0049] Step 7: Place the inner door liner 25 into the second mold.

[0050] Step 8: Close the first mold and the second mold together. After the foaming material is cured, a foam layer 26 is formed.

[0051] The refrigerator door obtained through the above steps has magnetic attraction, which can attract items such as refrigerator magnets. Furthermore, the use of magnetic metal plates can reduce the price of the refrigerator. This solution can be applied to various refrigerator models, which is conducive to large-scale promotion.

[0052] Example 3.

[0053] Based on the above technical solutions, this embodiment provides another refrigerator door and refrigerator, which adds a magnetic ink layer to the above embodiment to improve the magnetic attraction.

[0054] The refrigerator provided in this embodiment includes a refrigerator compartment, a freezer compartment, and a variable-temperature compartment, arranged vertically. The refrigerator compartment has a refrigerator door, and the variable-temperature compartment can be located inside the refrigerator compartment, sharing a refrigerator door with it. Alternatively, the variable-temperature compartment has its own door. The freezer compartment has a freezer door, or the freezer compartment can be a drawer structure.

[0055] The refrigerator door, freezer door, and variable temperature compartment door can have various layouts, such as top and bottom arrangement, top, middle and bottom arrangement, and cross door. The technical solution provided in this embodiment can be used for all refrigerator doors.

[0056] This embodiment is only used as an example. Figure 1 Taking the refrigerator shown as an example, the refrigerator includes a main body 1 and refrigerator doors 2, which are specifically two double-opening refrigerator compartment doors. Below the refrigerator compartments is a freezer compartment, which is a drawer.

[0057] In the diagram, the X direction represents the width of the refrigerator, the Y direction represents the depth of the refrigerator, and the Z direction represents the height of the refrigerator.

[0058] like Figure 3 As shown, the refrigerator door 2 includes: a glass substrate 21, a varnish layer 22, an appearance pattern layer 23, a magnetic metal plate 24, and a magnetic ink layer 27.

[0059] The glass substrate 21 can be ordinary glass or tempered glass, and has a first surface and a second surface. The first surface is the surface located on the outside of the refrigerator after the refrigerator door 2 is installed in the refrigerator, that is, the first surface of the glass substrate 21 faces outward and the second surface faces inward.

[0060] The varnish layer 22 is disposed on the first surface of the glass substrate 21, for example, the varnish layer 22 can be formed on the first surface of the glass substrate 21 by screen printing process.

[0061] A magnetic ink layer 27 is disposed on the surface of the varnish layer 22, for example, by screen printing. The magnetic ink layer 27 contains magnetic metal powder and has magnetic attraction capability.

[0062] The appearance pattern layer 23 is disposed on the surface of the magnetic ink layer 27, for example, the appearance pattern layer 23 can be formed on the surface of the magnetic ink layer 27 by screen printing process.

[0063] A magnetic metal plate 24 is disposed on the second surface of the glass substrate 21. The magnetic metal plate 24 is made of a metal with magnetic attraction capabilities, such as an iron plate or a steel plate, and can attract permanent magnets by magnetic force. If an iron plate is used, rust prevention treatment can be carried out by means of plating or coating with anti-rust paint. Specifically, the steel plate can be a galvanized steel plate.

[0064] In the above scheme, both the magnetic ink layer 27 and the magnetic metal plate 24 have magnetic attraction capabilities. The simultaneous placement of both can enhance the magnetic attraction capability and enable the adsorption of refrigerator magnets with greater weight.

[0065] The technical solution provided in this embodiment uses a glass substrate for the refrigerator door. The glass substrate has a first surface and a second surface, with the first surface being the surface on the outside of the refrigerator after the door is installed. A varnish layer is disposed on the first surface of the glass substrate; a magnetic ink layer is disposed on the surface of the varnish layer; an appearance pattern layer is disposed on the surface of the magnetic ink layer; a magnetic metal plate is disposed on the second surface of the glass substrate; a door liner is disposed on the surface of the magnetic metal plate; and a foam layer is formed between the magnetic metal plate and the door liner. Both the magnetic metal plate and the magnetic ink layer have magnetic attraction capabilities, which can improve the magnetic attraction and attract refrigerator magnets of greater weight. Furthermore, the cost of the magnetic metal plate is much lower than that of magnetic ink, which can reduce the price of the refrigerator. This solution can be applied to various refrigerator models, facilitating large-scale promotion. In addition, the manufacturing process using the magnetic metal plate is simpler, which can improve the yield rate, reduce manufacturing costs, and further reduce the price of the refrigerator.

[0066] In addition, the refrigerator door 2 also includes an inner door liner 25 and a foam layer 26. The inner door liner 25 is disposed on the surface of the magnetic metal plate 24, and the foam layer is formed between the magnetic metal plate 24 and the inner door liner 25. The foam layer can firmly bond the magnetic metal plate 24, the inner door liner 25, the glass substrate 21, and the door frame to form the door structure.

[0067] The thickness of the glass substrate 21 is 1.2mm-2.5mm, and can be one of 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, or 2.5mm, or it can be accurate to two decimal places.

[0068] The thickness of the magnetic metal plate 24 is 0.1mm-1.5mm, specifically one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm, or it can be accurate to two decimal places.

[0069] The combination of glass substrates 21 of varying thicknesses with magnetic metal plates 24 yielded a magnetic attraction force of 6.5N-11N, sufficient to attract everyday refrigerator magnets. A magnetic attraction force of 6.5N is sufficient to firmly attach a regular refrigerator magnet to the refrigerator.

[0070] One specific implementation scheme is as follows: a 2.0mm thick glass substrate 21 is combined with a 0.5mm thick magnetic metal plate 24, and a magnetic ink layer 27 is added, so that the magnetic attraction force can reach 7.9N-9.5N.

[0071] Another specific implementation scheme is to combine a 2.3mm thick glass substrate 21 with a 1.5mm thick magnetic metal plate 24, and add a magnetic ink layer 27, so that the magnetic attraction force can reach 6.5N-8.5N.

[0072] In addition, the thickness of the varnish layer 22 is 5μm-80μm, specifically 5μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, ... 20μm, 21μm, ... 30μm, 31μm, ... 40μm, 41μm, ... 50μm, 51μm, ... 60μm, 61μm, ... 70μm, 71μm, ... 80μm, and can be accurate to one decimal place.

[0073] The thickness of the pattern layer 23 is typically 10μm-150μm, but can also be greater than 150μm, depending on the pattern design and tactile feel. The thickness of the magnetic ink layer 27 is 0.05mm-0.2mm, specifically: 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.2mm, or accurate to three decimal places.

[0074] Compared with the traditional solution, in this embodiment, the magnetic ink layer 27 is thinner, which can reduce the number of screen printing steps, thereby reducing the number of processes and reducing the appearance defect rate.

[0075] The magnetic metal plate 24 has high magnetic permeability, providing a stable and strong magnetic substrate to compensate for the magnetic attraction of the magnetic ink layer 27. Overall, its magnetic performance is superior to traditional thick magnetic ink solutions. Furthermore, the magnetic metal plate 24 is positioned on the back of the glass substrate, maintaining the glass's appearance and texture.

[0076] Example 4.

[0077] Based on the above embodiments, this embodiment provides a method for manufacturing a refrigerator door, used to manufacture the refrigerator door provided in Embodiment 3. The manufacturing method includes the following steps: Step 1: A varnish layer is formed on the first surface of the glass substrate using a screen printing process.

[0078] A varnish layer 22 is printed over the entire first surface of the glass substrate 21, with a thickness of 5μm-80μm. On one hand, printing the varnish layer 22 can reduce the specular reflection of the glass substrate 21 and reduce its transparency. On the other hand, the varnish layer 22 can also increase the adhesion between the magnetic ink layer 27 and the glass substrate 21, improving the adhesion of the magnetic ink layer 27.

[0079] Step 2: A magnetic ink layer is formed on the surface of the varnish layer using a screen printing process.

[0080] A magnetic ink layer 27 is printed on the entire surface of the varnish layer 22. The magnetic ink layer 27 contains iron powder or magnetic powder and has magnetic attraction capability. The thickness of the magnetic ink layer 27 is 0.05mm-0.2mm.

[0081] Step 3: Form an appearance pattern layer on the surface of the magnetic ink layer using a screen printing process.

[0082] An appearance pattern layer 23 is formed by printing on the entire surface of the magnetic ink layer 27. The appearance pattern layer 23 can be formed using an appropriate screen printing plate, such as a grid or stripe shape, to give the outer surface of the refrigerator door a specific texture. The appearance pattern layer 23 can also have a specific color, which can match the color of the varnish layer 22. The thickness of the appearance pattern layer 23 is 10μm-150μm.

[0083] Step 4: Install and fix the glass substrate to the door frame to form the door shell assembly.

[0084] This step can be achieved using conventional methods, such as fixing by clamping, hot melt adhesive, etc.

[0085] Step 5: Place the door shell assembly into the first mold, so that the first surface of the glass substrate faces the inside of the first mold.

[0086] Step 6: Fix the magnetic metal plate on the second surface of the glass substrate.

[0087] The magnetic metal plate 24 can be adhered to the surface of the glass substrate 21 with tape, thereby improving its firmness.

[0088] Furthermore, it also includes the following steps: Step 7: Inject foam material onto the surface of the magnetic metal plate.

[0089] The foaming material can be polyurethane foam.

[0090] Step 8: Place the inner door liner into the second mold.

[0091] Step 9: Close the first mold and the second mold together, and the foamed material will solidify to form a foamed layer.

[0092] The thickness of the glass substrate 21 is 1.2mm-2.5mm, and the thickness of the magnetic metal plate 24 is 0.1mm-1.5mm. The magnetic attraction force of the magnetic metal plate 24 and the magnetic ink layer 27 can reach 6.5N-11N, which can meet the adsorption requirements of the refrigerator door.

[0093] The technical solution provided in this embodiment involves forming a varnish layer on the first surface of a glass substrate using a screen printing process; forming a magnetic ink layer on the surface of the varnish layer using a screen printing process; forming an appearance pattern layer on the surface of the magnetic ink layer using a screen printing process; installing and fixing the glass substrate to a door frame to form a door shell assembly; placing the door shell assembly in a first mold with the first surface of the glass substrate facing inwards towards the mold; and fixing a magnetic metal plate to the second surface of the glass substrate. Since both the magnetic metal plate and the magnetic ink layer possess magnetic attraction capabilities, the magnetic attraction is enhanced, allowing for the adsorption of heavier refrigerator magnets. Furthermore, the cost of the magnetic metal plate is significantly lower than that of magnetic ink, reducing the price of the refrigerator. This solution can be applied to various refrigerator models, facilitating large-scale promotion. Additionally, the manufacturing process using the magnetic metal plate is simpler, increasing the yield rate and reducing manufacturing costs, further lowering the refrigerator's price.
