Finally, a three-color printing process (forming a masking color printing layer and a protective layer) is performed to ensure the opacity of the color printing layer and to ensure the durability of the door.
[0110] However, there are design limitations because the conventional materials used to ensure the reflectivity of the door are limited to metals or metal oxides, so it is impossible to ensure both reflectivity and transmittance at the same time. Furthermore, metals or metal oxides are not only susceptible to alkaline environments but also have failure problems due to electrical conduction.
[0111] The configuration of Control Panel 210 and the function of each configuration will be described in more detail below. Figure 7 This is a view showing the structure of a control panel according to an embodiment of the present invention.
[0112] According to the disclosed embodiments, the control panel 210 may consist of a glass 211, a coating 212 having gaps on the upper surface of the glass 211, a first printed layer 213 stacked in a shape corresponding to the upper surface of the coating 212, and a second printed layer 214 stacked on the upper surface of the first printed layer 213 and provided adjacent to the glass 211.
[0113] Glass 211 may have a flat shape on which coating 212 can be placed, and may be made of a transparent material with high visible light transmittance. For example, glass 211 may be made of a material with visible light transmittance in the range of 80% to 100% to meet the transmittance required for use as the upper panel of door 20. Furthermore, considering the durability and intended use of door 20, glass 211 may be provided with a thickness of 2 to 6 mm.
[0114] Coating 212 is a layer provided to ensure the visibility and insulation of control panel 210. In this invention, coating 212 is made of silicon nitride, silicon oxide and combinations thereof, which have excellent resistance.
[0115] silicon nitride (SiN) x ) and silicon nitride oxide (SiNO) x Silicon nitride (SiN) is an insulating material and an inorganic material with excellent mechanical properties, especially impact resistance. In this invention, silicon nitride (SiN) can be used... x ) and silicon nitride oxide (SiNO) x To ensure the insulation of door 20, silicon nitride (SiN) x ) and silicon nitride oxide (SiNO) x As a non-oxide ceramic compared to SiO x It is more robust and has better resistance to scratches or mechanical damage, and has a dielectric constant of 7.5 and a resistivity of 0.6 Ωcm, making it suitable as a material for the door 20 of the garment care device 1.
[0116] For example, AlSiN x CrSiN x TiSiNx AlSiNO x These can be used in silicon nitrides and silicon oxides.
[0117] With the development of materials such as silicon nitride (SiN) x ) or silicon nitride oxide (SiNO x The increased content of insulating ceramic material in the coating 212 can prevent electrical conduction. In other words, with the increase of silicon nitride (SiN) content, the electrical conductivity of the coating 212 can be prevented. x ) or silicon nitride oxide (SiNO x As the content of ) increases, the resistance of coating 212 increases. Therefore, when 1000V is applied from the insulation tester, it can be ensured that the resistance of the coating reaches 500MΩ or greater.
[0118] When only the insulation properties of coating 212 are considered, silicon nitride (SiN) x ) or silicon nitride oxide (SiNO x The higher the content of silicon nitride (SiN), the better. However, considering that when the content of silicon nitride (SiN) is higher... x ) or silicon nitride oxide (SiNO x When the content of silicon nitride (SiN) is too high, the transmittance cannot be guaranteed. In this invention, the silicon nitride (SiN) content of coating 212 is... x ) or silicon nitride oxide (SiNO x The content of ) is limited to the range of 70% to 90%.
[0119] Meanwhile, according to the disclosed embodiments, the coating 212 based on silicon nitride or silicon oxide nitride may be doped with or laminated with elements selected from Al. x O y 、Nb x O y and SiO x One or more groups that make up a group.
[0120] Furthermore, according to the disclosed embodiments, the coating 212 may be doped with or laminated with one or more nanoparticles selected from the group consisting of Si, Ni, Cr, Nb, Zr, Co, Ti and Ag.
[0121] Meanwhile, as the thickness of coating 212 increases, the reflectivity increases. In this invention, considering both the reflectivity and transmittance of control panel 210, the thickness of coating 212 can be limited to 30 to 100 nm.
[0122] At the same time, Figure 7 In this process, the gap between the coatings 212 can be appropriately adjusted according to the implementation of the door color, color difference value, reflectivity, transmittance, etc., and is provided by introducing laser marking etching of the coatings 212, which will be described below.
[0123] The first printing layer 213 is provided as the basic color for realizing the gate 20, and can be provided as black, burgundy, pink, ivory, and gold. However, the color of the first printing layer 213 is not limited to these, and can be provided as a variety of colors in a high chromaticity series.
[0124] Reference Figure 7 The first printed layer 213 formed on the upper surface of the coating 212 can be provided in a shape corresponding to the coating 212 and provided on the lower surface of the second printed layer 214 adjacent to the glass 211.
[0125] The second printed layer 214 is a layer in which a logo of a company or organization is formed by graphics, characters, symbols or combinations thereof to identify the manufacturer of the garment care equipment 1.
[0126] In addition, the second printed layer 214 is a layer that implements the user interface, including clothing handling options, operation time, remaining time and other menus.
[0127] Reference Figure 7 According to the disclosed embodiment, the second printed layer 214 can be provided as a laminate on the upper surface of the first printed layer 213 and adjacent to the glass 211.
[0128] Figure 7 The second printed layer 214 is shown to be T-shaped, but the shape of the second printed layer 214 is not limited to this. It can be provided in various shapes with regard to the above-mentioned logo and user interface, as long as it is stacked on the upper surface of the first printed layer 213 and adjacent to the glass 211 by filling the gap between the coating layer 212 and the first printed layer 213.
[0129] Additionally, the control panel 210 according to the disclosed embodiment may also include a protective layer 215 formed on the upper surface of the second printed layer 214.
[0130] When the second printed layer 214 is directly exposed to the atmosphere, it will corrode and its durability will decrease in the long term. To solve this problem, the control panel 210 may include a protective layer 215, which is located above the second printed layer 214, that is, at the top of the control panel 210.
[0131] The protective layer 215 may comprise one or more of the group consisting of metal oxides, metal nitrides, metal nitrides and combinations thereof.
[0132] The following effects can be expected from the door 20 of the control panel 210, which is equipped with the coating 212 and the second printing layer 214 provided as described above.
[0133] First, in the control panel 210 according to the disclosed embodiment, the transmittance of light passing in the direction from the second printed layer 214 toward the coating 212 can be 20% or greater, specifically in the range of 20% to 70%, and the reflectance of light can be 70% or less, specifically in the range of 20% to 70%.
[0134] In other words, by ensuring the reflectivity of the door 20 through the introduction of gaps between the coatings 212, the control panel 210 according to the disclosed embodiment can not only be used as a mirror for inspecting the user's appearance, but can also be implemented in various colors with high chromaticity.
[0135] Furthermore, by using silicon nitride (SiN) as an insulating material x ) and silicon nitride oxide (SiNO) x By incorporating this into the coating, the control panel 210, according to the disclosed embodiment, can solve the problem of electrical conduction. Specifically, when 1000V is applied from an insulation tester, the resistance of the coating can be found to be 500MΩ or greater, thereby preventing malfunctions of the garment care equipment due to electrical conduction.
[0136] Next, a method for manufacturing a garment care device according to another embodiment of the present invention will be described.
[0137] As mentioned above, conventionally, after cutting the mother glass, a separate deposition method is used to form the coating used as a mirror.
[0138] The present invention aims to ensure the visibility (eye-catching shape or color characteristics) of the door 20, including the control panel 210, by introducing a method of forming a coating on the mother glass, forming a color layer after cutting and processing the coating, partially removing the coating / printing layer by laser marking, and then printing.
[0139] Figure 8 This is a view illustrating the process of manufacturing a control panel according to an embodiment of the present invention.
[0140] A method for manufacturing a garment care device according to one embodiment of the present invention includes: by selecting SiN... x or SiNO x One or more of the groups thereof are applied to the mother glass to form a coating; a color printing layer is laminated after a strengthening heat treatment is performed on the formed coating; the coating and the color printing layer are etched with a fiber laser; and a logo / UI printing layer is formed so that it is adjacent to the glass and laminated on the upper surface of the color printing layer.
[0141] According to one embodiment of the invention, the control panel 210 employs a method of forming a coating 212 on the entire surface of the mother glass 211, followed by processing and printing, thus being configured to minimize differences between final products and ensure process efficiency.
[0142] Coating 212 can be achieved by coating the mother glass 211 with a coating containing SiN selected from SiN. x or SiNO x It is formed by one or more insulating materials in combination with other materials.
[0143] Furthermore, coating 212 may contain or be laminated with selected Al. x O y 、Nb x O y and SiO x One or more groups that make up a group.
[0144] In addition, the coating 212 may be doped with or laminated with one or more nanoparticles selected from the group consisting of Si, Ni, Cr, Nb, Zr, Co, Ti and Ag.
[0145] The method for forming coating 212 on mother glass 211 is not particularly limited thereto, and can be performed by methods known in the art. For example, the method may include physical vapor deposition sputtering methods (DC, RF, MF, and reactive coating), chemical vapor deposition (CVD) methods, thermal deposition methods, electron beam deposition methods, etc.
[0146] Next, processes can be performed to form a coating 212 on the mother glass 211, then cut the coating 212 to the required size, and process the edges by introducing a computer numerical control (CNC) method.
[0147] Subsequently, a strengthening heat treatment process is performed on the treated coating 212. According to the disclosed embodiment, the heat treatment can be performed at a temperature of 650 to 700°C. In this invention, the heat treatment can be performed at a temperature of 650°C or higher to improve the uniform strength of the laminated structure including glass 211 and coating 212. However, because there is a problem that the heat resistance of the laminated structure decreases when heat treatment is performed at excessively high temperatures, the temperature range of the strengthening heat treatment is limited to 700°C or lower.
[0148] Next, a color printing layer 213 is laminated on the coating 212, which has undergone a heat-strengthening treatment. The color printing layer 213 is provided to achieve the basic color of the door 20, and can be provided in various colors such as black, burgundy, pink, ivory and gold.
[0149] Meanwhile, in this invention, the operation of forming a color printing layer 213 and then etching the color printing layer 213 with a fiber laser is introduced to ensure the visibility of the door 20.
[0150] For example, after the color printing layer 213 is formed and before the logo / UI printing layer 214 is formed, an etching process can be performed using a fiber laser to remove the coating 212 and the color printing layer 213.
[0151] The present invention aims to solve the problems of poor stains on the printed layer and the decline in printing quality due to glass damage by controlling the frequency of the fiber laser to 50 to 100 Hz, and to ensure the surface quality of the door.
[0152] Considering cost and productivity depending on the process load, the etching process can be performed in 10 to 60 seconds.
[0153] Next, the logo / UI printing layer 214 is formed adjacent to the glass 211 and stacked on the upper surface of the color printing layer 213.
[0154] The logo / UI printing layer 214 can be provided on the door 20 as a layer for implementing a logo or user interface.
[0155] Furthermore, the manufacturing method of the garment care device according to the disclosed embodiments may also include forming a protective layer on the upper surface of the label / UI printing layer. The protective layer 215 may comprise one or more of the following: metal oxides, metal nitrides, metal oxynitrides, and combinations thereof.
[0156] The visibility and conductivity of the door 20, based on the material constituting the coating 212 of the control panel 210 according to the disclosed embodiment, will be described in detail below. The examples described below are provided merely to aid in understanding the invention, and the spirit of the invention is not limited to the examples described below.
[0157] SiN will be used through PVD sputtering. x and SiNO x After the series of coating materials, which are the main components, are deposited on the glass substrate, a coating is formed on the glass substrate through a series of processes such as cutting, CNC machining, and heat treatment. At this time, the heat treatment is performed at 665°C for 10 minutes.
[0158] Next, a color-printed layer with colors according to Tables 1 to 3 is formed using a single-color printing process. Then, a laser marking process is performed at a speed of 1700 m / s, a frequency of 70 Hz, and 80% power to etch the coating and color-printed layer. The logo / UI printing layer is then bonded to the glass together with the color-printed layer. Finally, the door 20 of the garment care device 1 is manufactured by layering the top protective layer.
[0159] The results of the reflectivity, transmittance, color difference, and conductivity tests (applied from an insulation tester at 1000V) of the front and coated surfaces of the door glass are shown in Tables 1 to 3 below.
[0160] In Tables 1 to 3, L refers to the brightness index of the color, and a* and b* refer to the chromaticity index of the color.
[0161] [Table 1]
[0162]
[0163] [Table 2]
[0164]
[0165] [Table 3]
[0166]
[0167] Referring to Tables 1 to 3, when silicon nitride (SiN) is included... x ) or silicon nitride oxide (SiNO x When the coating is applied to the door glass according to the invention, it can be seen that both reflectivity and transmittance have a complementary relationship, thereby improving visibility.
[0168] Specifically, in Examples 1 through 6, it was found that the reflectivity was 70% or less and the transmittance was 20% or more.
[0169] Furthermore, in all Examples 1 to 6, the physical property criteria required to resolve faults caused by electrical conduction were confirmed to be met because the resistance measured when 1000V was applied from the insulation tester was 500MΩ or greater.
[0170] Meanwhile, Comparative Example 1 uses SiO2 and Nb2O5 as coating materials, and it was found that the resistance measured when 1000V was applied from the insulation tester was 0.5MΩ.
[0171] As described above, the control panel according to the disclosed embodiments can provide a garment care device that not only solves the problem of failure due to electrical conduction but also ensures reflectivity and transmittance by using silicon nitride or silicon nitride, which are insulating materials, as the reflective layer. This garment care device is capable of matching indoor colors.
[0172] Furthermore, the control panel according to the disclosed embodiments can employ a method of forming a coating on the entire surface of the mother glass, followed by processing and printing, thereby minimizing differences between final products and ensuring process efficiency.
[0173] Specific embodiments have been shown and described above. However, the present invention is not limited to the above embodiments, and those skilled in the art will be able to make various modifications to the invention without departing from the spirit of the invention as described in the appended claims.
