Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a pot cover for cooking appliances. Background Art
[0002] IMD is the abbreviation of In-Mold Decoration, which is injection molding surface decoration technology. It injection molds the decorative layer and the substrate together, so that the product not only has an aesthetically pleasing appearance, but also has good wear resistance, scratch resistance, anti-fouling and other properties. It is mainly used in the surface decoration and functional panels of household appliances. The IMD panel with IMD technology is provided with text and pattern information. When the light-emitting device is illuminated, the pattern and text on the IMD panel are visible. Otherwise, the pattern and text on the IMD panel cannot be seen, thereby achieving a hidden effect of the pattern and text, making the IMD panel a hidden display panel. The IMD panel can also protect the pattern and text from being rubbed or scratched. Based on this, more and more cooking utensils are beginning to use IMD panels for pot lids. In order to make the pattern and text have a better display effect, the industry will use metal gold or silver to form the pattern and text. The existing metal material molding process on the substrate generally adopts the following two methods:
[0003] The first method is to use electroplating technology, but the heat and humidity resistance of electroplated gold or silver is poor, and the temperature resistance is about 90℃.
[0004] The second method is printing. When using printing, if you want to present a metallic color effect, you need to add a metal mixture to the printing medium to enhance its glossiness. However, the metal mixture has poor adhesion to the printing medium and cannot adapt to high temperature and high humidity environments.
[0005] During the use of cooking appliances, the high-temperature steam in the cooking cavity needs to be discharged through the exhaust port on the pot lid. Therefore, the IMD panel is exposed to a high-temperature and high-humidity environment for a long time, which can easily cause the IMD panel adjacent to the exhaust port to warp or the base layer and the decorative layer to separate, affecting the service life of the IMD panel. Utility Model Content
[0006] The present application provides a pot cover for a cooking utensil to solve the technical problem of delamination or warping of an IMD panel adjacent to a steam exhaust port due to high temperature and high humidity.
[0007] The technical solutions adopted in this application are:
[0008] A pot cover for a cooking utensil comprises a cover body and an IMD panel mounted on the cover body, the IMD panel comprising a substrate and a decorative layer integrally injection-molded with the substrate, at least a portion of the decorative layer being adhered to the outer surface of the substrate, the substrate being provided with a steam exhaust port, the decorative layer being arranged around the steam exhaust port, an ink protective layer being further adhered to the surface of the substrate, the ink protective layer being arranged around the steam exhaust port and being located on the inner circumference of the decorative layer.
[0009] The cooking pot cover in this application also includes the following additional technical features:
[0010] The substrate has a partition area between the outer periphery of the steam outlet end and the inner periphery of the decorative layer, and at least a portion of the ink protection layer is attached to the outer surface of the partition area.
[0011] The ink protection layer extends to cover the inner side wall of the steam exhaust port.
[0012] At least a portion of the ink protection layer is attached to the inner side wall of the steam exhaust port.
[0013] The pot cover has a hinged side hinged to the pot body of the cooking utensil and a free side away from the hinged side. The substrate has a first end close to the hinged side and a second end opposite to and away from the first end. The decorative layer extends to the outer surface of the first end. The first end has a bending surface adjacent to its outer surface, and the bending surface is also attached with the ink protective layer.
[0014] The width of the ink protection layer is W, and W satisfies: W≥1.2mm.
[0015] The pot cover also includes a steam valve and a lining cover installed on the cover body, the steam valve has a steam inlet and a steam outlet, the lining cover is provided with an exhaust pipe connected to the steam outlet, the exhaust pipe extends from the exhaust port to the outside of the pot cover so that the exhaust end of the exhaust pipe is higher than the outer periphery of the exhaust port.
[0016] The pot lid also includes a steam valve and a lining cover installed on the cover body, the steam valve has a steam inlet and a steam outlet, the lining cover is provided with an exhaust pipe connected to the steam outlet, the exhaust pipe passes through the exhaust port, the exhaust port has a first section and a second section located inside the first section, a first insulation gap is provided between the exhaust pipe and the inner wall surface of the first section, a second insulation gap is provided between the exhaust pipe and the inner wall surface of the second section, and the radial dimension of the second insulation gap is greater than the radial dimension of the first insulation gap.
[0017] The pot lid also includes a steam valve and a lining cover installed on the cover body, the steam valve has a steam inlet and a steam outlet, the lining cover is provided with an exhaust pipe connected to the steam outlet, the exhaust pipe passes through the exhaust port, the exhaust pipe has an exhaust channel connecting the steam outlet and the outside world, and an insulating cavity arranged around the exhaust channel, the insulating cavity and the projection of the substrate in the axial direction of the exhaust pipe at least partially overlap.
[0018] The decorative layer and the ink protection layer are both printed on the substrate.
[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0020] 1. The IMD panel in the present application is surrounded by the steam exhaust port and is provided with an ink protective layer on the inner peripheral side of the decorative layer: on the one hand, during the use of the cooking utensil, high-temperature and high-humidity steam is discharged from the steam exhaust port. The presence of the ink protective layer can seal the decorative layer and the substrate located on its outer peripheral side, preventing high-temperature and high-humidity steam from entering between the decorative layer and the substrate attachment area corresponding to the decorative layer, thereby solving the technical problems of separation between the substrate and the decorative layer and warping of the decorative layer; on the other hand, the ink protective layer has stronger adhesion ability than the decorative layer. By setting the ink protective layer at the position of the steam exhaust port, the ink protective layer itself is not easy to fall off, thereby improving the protection effect of the decorative layer.
[0021] Furthermore, during the actual cooking process, the steam vent will not only discharge high-temperature steam, but in the event of an overflow, soup, rice paste, and other substances containing oil, sticky matter, etc. may overflow from the steam vent. The ink protective layer has strong non-stickiness and easy-to-clean properties, making it easier to remove grease and food residues attached to the periphery of the steam vent. Compared with the decorative layer, the ink protective layer has stronger wear resistance and chemical resistance. Therefore, during the cleaning process, the ink protective layer is not easily scratched, worn, or chemically corroded. While ensuring the service life of the ink protective layer, the protective effect of the ink protective layer on the decorative layer can be guaranteed.
[0022] In addition, during the injection molding process of the IMD panel in this application, the presence of the ink protection layer can protect the decorative layer from direct impact and chemical corrosion of the high-temperature molten plastic, thereby avoiding damage to the decorative layer or color different from the expected color.
[0023] 2. As a preferred embodiment of the present application, a partition area is provided between the outer periphery of the steam outlet end of the substrate and the inner periphery of the decorative layer, and at least part of the ink protective layer is attached to the outer surface of the partition area. The design of the partition area can form a protective area around the steam outlet, so that the inner periphery of the decorative layer is away from the high-temperature and high-humidity steam. The ink protective layer covers the outer surface of the partition area, which helps to protect the decorative layer from erosion by hot steam or oil smoke during cooking, thereby improving the protective effect of the decorative layer. In addition, during the injection molding process, the molten plastic may cause an impact on the decorative layer. The provision of the partition area and the ink protective layer attached to the partition area can serve as a buffering means to reduce the direct impact of the molten plastic on the decorative layer and protect the patterns and text on the decorative layer from being damaged.
[0024] 3. As a preferred embodiment of the present application, the width of the ink protection layer is greater than or equal to 1.2 mm, so that the ink protection layer has a wider coverage range, further improving the protective effect of the ink protection layer on the decorative layer. Moreover, during the injection molding process, the wider ink protection layer can reduce the damage to the ink protection layer caused by mold pressure or injection material flow, further reducing the impact that the molten plastic may have on the decorative layer.
[0025] 4. As a preferred embodiment of the present application, the pot lid is equipped with a steam exhaust pipe. The exhaust end of the steam exhaust pipe is higher than the outer perimeter of the exhaust port. After exiting the steam exhaust pipe, the high-temperature steam rises directly to diffuse. This reduces direct contact and potential damage to the decorative layer caused by the high-temperature and high-humidity steam, thereby reducing the risk of fading, deformation, or damage to the decorative layer due to prolonged heat exposure. Furthermore, when steam is discharged through the steam exhaust pipe and condenses during its rise and cooling process, the higher exhaust pipe helps prevent the condensation from flowing back onto the surface of the decorative layer, thereby avoiding damage to the decorative layer or cleaning problems that may be caused by high humidity environments.
[0026] 5. As a preferred embodiment of the present application, the steam exhaust port has a first section and a second section located inside the first section, a first thermal insulation gap is provided between the steam exhaust pipe and the inner wall surface of the first section, a second thermal insulation gap is provided between the steam exhaust pipe and the inner wall surface of the second section, a radial dimension of the second thermal insulation gap is larger than a radial dimension of the first thermal insulation gap, the radial dimension of the first thermal insulation gap is smaller, which can reduce the probability of external impurities entering the interior of the pot cover through the first thermal insulation gap, thereby forming effective protection for the components inside the pot cover, and the radial dimension of the second thermal insulation gap is larger, which can reduce the heat transfer from the steam exhaust pipe to the IMD panel, thereby reducing the temperature rise of the IMD panel, and further reducing the probability of the decorative layer warping or the decorative layer separating from the substrate.
[0027] 6. As a preferred embodiment of the present application, the exhaust pipe has an exhaust channel connecting the steam outlet and the outside world, and an insulation cavity arranged around the exhaust channel. The insulation cavity and the projection of the substrate in the axial direction of the exhaust pipe at least partially overlap. The setting of the insulation cavity can reduce the heat transfer from the exhaust pipe to the IMD panel, thereby reducing the temperature rise of the IMD panel, and further reducing the probability of the decorative layer warping or the decorative layer separating from the substrate.

[0049] like Figure 1 、 Figure 2 and Figure 5As shown, a pot cover for a cooking utensil includes a cover body and an IMD panel 1 installed on the cover body. The IMD panel 1 includes a substrate 11 and a decorative layer 12 integrally injection-molded with the substrate 11. At least a portion of the decorative layer 12 is attached to the outer surface of the substrate 11. The substrate 11 is provided with a steam exhaust port 14. The decorative layer 12 is arranged around the steam exhaust port 14. An ink protective layer 13 is also attached to the surface of the substrate 11. The ink protective layer 13 is arranged around the steam exhaust port 14 and is located on the inner peripheral side of the decorative layer 12.
[0050] As a preferred embodiment of the present application, the decorative layer 12 is used for printing patterns and / or texts, and the patterns and / or texts are made of metal powders such as gold or silver to enhance their coloring effect.
[0051] The IMD panel 1 in the present application is surrounded by the exhaust port 14 and is provided with an ink protective layer 13 on the inner peripheral side of the decorative layer 12: on the one hand, during the use of the cooking utensil, high-temperature and high-humidity steam is discharged from the exhaust port 14, and the presence of the ink protective layer 13 can seal the decorative layer 12 and the substrate 11 located on its outer peripheral side, preventing high-temperature and high-humidity steam from entering between the decorative layer 12 and the attachment area of the substrate 11 corresponding to the decorative layer 12, thereby solving the technical problems of separation between the substrate 11 and the decorative layer 12 and warping of the decorative layer 12; on the other hand, the ink protective layer 13 has stronger adhesion ability than the decorative layer 12. By setting the ink protective layer 13 at the position of the exhaust port 14, the ink protective layer 13 itself is not easy to fall off, thereby improving the protection effect of the decorative layer 12.
[0052] Furthermore, during the actual cooking process, the steam vent 14 will not only discharge high-temperature steam, but also, in the event of an overflow, soup, rice paste, or other substances containing oil, sticky matter, or the like may overflow from the steam vent 14. The ink protective layer 13 has strong non-stickiness and easy-to-clean properties, making it easier to remove grease and food residues attached to the periphery of the steam vent 14. Compared with the decorative layer 12, the ink protective layer 13 has stronger wear resistance and chemical resistance. Therefore, during the cleaning process, the ink protective layer 13 is not easily scratched, worn, or chemically corroded. While ensuring the service life of the ink protective layer 13, the protective effect of the ink protective layer 13 on the decorative layer 12 can be guaranteed.
[0053] In addition, during the injection molding process of the IMD panel 1 in this application, the presence of the ink protection layer 13 can protect the decorative layer 12 from direct impact and chemical corrosion of the high-temperature molten plastic, thereby avoiding damage to the decorative layer 12 or a color different from the expected color.
[0054] The present application does not limit the shape of the exhaust port 14, which can be circular or as Figure 5 The strip shape shown is, of course, also possible to adopt other shapes.
[0055] As a preferred embodiment of the present application, the decorative layer 12 and the ink protection layer 13 are both printed on the substrate 11, thereby simplifying the molding process of the IMD panel 1 and improving the adhesion effect of the decorative layer 12 and the ink protection layer 13 on the substrate 11.
[0056] In the present application, the attachment position of the ink protection layer 13 on the substrate 11 can adopt any one of the following embodiments:
[0057] Implementation method 1: Figure 5 As shown, a partition area is present between the outer periphery of the steam outlet end of the steam outlet 14 of the substrate 11 and the inner periphery of the decorative layer 12, and at least a portion of the ink protective layer 13 is attached to the outer surface of the partition area. The design of the partition area can form a protective area around the steam outlet 14, so that the inner periphery of the decorative layer 12 is away from high-temperature and high-humidity steam. The ink protective layer 13 covers the outer surface of the partition area, which helps protect the decorative layer 12 from erosion by hot steam or oil smoke during cooking, thereby improving the protective effect of the decorative layer 12. Moreover, during the injection molding process, the molten plastic may cause an impact on the decorative layer 12. The provision of the partition area and the ink protective layer 13 attached to the partition area can serve as a buffering means to reduce the direct impact of the molten plastic on the decorative layer 12, thereby protecting the patterns and text on the decorative layer 12 from being damaged. In addition, attaching the ink protective layer 13 to the partition area can form a visual contrast with the decorative layer 12, thereby enhancing the texture of the product.
[0058] Furthermore, in the first embodiment, the ink protection layer 13 may be arranged in a position according to the following embodiment 1 and / or embodiment 2.
[0059] Example 1: Figure 6 and Figure 7 As shown, the ink protection layer 13 extends to cover the inner side wall of the exhaust port 14. That is, the ink protection layer 13 extends from the partition area to the inner side of the exhaust port 14 and covers the inner side wall of the exhaust port 14. The inner side wall of the exhaust port 14 refers to Figure 7 The vertical structure 141 shown in FIG. This configuration increases the coverage of the ink protection layer 13 and reduces the probability of high-temperature steam entering between the ink protection layer 13 and the opposing substrate 11, thereby enhancing the secure adhesion of the ink protection layer 13 to the substrate 11 and ensuring the protective effect of the ink protection layer 13 on the decorative layer 12. Furthermore, the extended configuration of the ink protection layer 13 provides a wider coverage of the outer surface of the substrate 11, providing a good protective effect on the substrate 11 to a certain extent and extending the service life of the IMD panel 1.
[0060] Example 2: Figure 6 and Figure 8As shown, the pot lid has a hinged side hingedly connected to the pot body of the cooking utensil and a free side remote from the hinged side. The substrate 11 has a first end proximal to the hinged side and a second end opposite and remote from the first end. The decorative layer 12 extends to the outer surface of the first end. The first end has a curved surface 15 adjacent to the outer surface, and the curved surface 15 is also attached with an ink protective layer 13. In this embodiment, the outer surface is the exposed surface, that is, the exposed portion is the outer surface relative to the portion concealed within the pot lid. The cover body includes a face cover 3 and a decorative part 2. The decorative part 2 is installed on the face cover 3, and the IMD panel 1 is installed on the decorative part 2. The decorative part 2 has an embedding groove adapted to the IMD panel 1. The bending surface 15 is adjacent to the outer surface of the first end, and the bending surface 15 abuts against the inner wall surface of the embedding groove. Compared with the decorative layer 12, the ink protective layer 13 has higher wear resistance. The ink protective layer 13 is attached to the bending surface 15. During the assembly process of the IMD panel 1 and the decorative part 2, the wear resistance of the ink protective layer 13 makes it not easily damaged, thereby extending the service life of the IMD panel 1.
[0061] Implementation method 2: Figure 6 and Figure 7 As shown, at least part of the ink protection layer 13 is attached to the inner side wall of the exhaust port 14. The inner side wall of the exhaust port 14 is as shown in FIG. Figure 7 The facade structure 141 is shown.
[0062] As a preferred embodiment of the second embodiment, Figure 6 and Figure 8 As shown, the pot lid has a hinged side hingedly connected to the pot body of the cooking utensil and a free side remote from the hinged side. The substrate 11 has a first end proximal to the hinged side and a second end opposite and remote from the first end. The decorative layer 12 extends to the outer surface of the first end. The first end has a curved surface 15 adjacent to the outer surface, and the curved surface 15 is also attached with an ink protective layer 13. In this embodiment, the outer surface is the exposed surface, that is, the exposed portion is the outer surface relative to the portion concealed within the pot lid. The cover body includes a face cover 3 and a decorative part 2. The decorative part 2 is installed on the face cover 3, and the IMD panel 1 is installed on the decorative part 2. The decorative part 2 has an embedding groove adapted to the IMD panel 1. The bending surface 15 is adjacent to the outer surface of the first end, and the bending surface 15 abuts against the inner wall surface of the embedding groove. Compared with the decorative layer 12, the ink protective layer 13 has higher wear resistance. The ink protective layer 13 is attached to the bending surface 15. During the assembly process of the IMD panel 1 and the decorative part 2, the wear resistance of the ink protective layer 13 makes it not easily damaged, thereby extending the service life of the IMD panel 1.
[0063] As a preferred embodiment of the present application, Figure 5As shown, the width of ink protection layer 13 is W, satisfying the following condition: W ≥ 1.2 mm. When ink protection layer 13 is positioned in the partition area, width W refers to the distance between the partition area adjacent to the outer periphery of steam outlet 14 and the partition area adjacent to the inner periphery of decorative layer 12. When ink protection layer 13 is positioned on the inner sidewall of steam outlet 14 in the second embodiment described above, width W refers to the height of facade structure 141.
[0064] The width of the ink protection layer 13 is greater than or equal to 1.2 mm, which can give the ink protection layer 13 a wider coverage range, further improving the protection effect of the ink protection layer 13 on the decorative layer 12. Moreover, during the injection molding process, the wider ink protection layer 13 can reduce the damage to the ink protection layer 13 caused by mold pressure or injection material flow, further reducing the impact that the molten plastic may have on the decorative layer 12.
[0065] Furthermore, the width of the ink protection layer 13 is greater than or equal to 1.5 mm, so as to further improve the coverage of the ink protection layer 13 and enhance the protection effect of the ink protection layer 13 on the decorative layer 12 during the injection molding process and the subsequent use of the cooking utensil.
[0066] In order to further enhance the protective effect of the decorative layer 12 in the present application, the present application may adopt the following embodiment 3, embodiment 4, and / or embodiment 5:
[0067] Implementation method three: Figure 3 and Figure 4 As shown, the pot lid also includes a steam valve 5 and a lining cover 4 mounted on the lid body. The steam valve 5 has a steam inlet and a steam outlet. The lining cover 4 is provided with a steam exhaust pipe 6 connected to the steam outlet. The steam exhaust pipe 6 extends from the steam outlet 14 to the outside of the pot lid, so that the exhaust end of the steam exhaust pipe 6 is higher than the outer periphery of the steam outlet 14. The exhaust end of the steam exhaust pipe 6 is higher than the outer periphery of the steam outlet 14. After being discharged from the steam exhaust pipe 6, the high-temperature steam rises directly to diffuse. This reduces direct contact and potential damage to the decorative layer 12 caused by the high-temperature and high-humidity steam, thereby reducing the risk of fading, deformation, or damage to the decorative layer 12 caused by prolonged heat exposure. Furthermore, when the steam is discharged through the steam exhaust pipe 6 and condenses during its rise and cooling process, the higher exhaust pipe 6 helps prevent the condensed water from flowing back onto the surface of the decorative layer 12, thereby avoiding damage to the decorative layer 12 or cleaning problems that may be caused by high humidity environments.
[0068] The third embodiment does not limit the connection method between the exhaust pipe 6 and the liner cover 4. The exhaust pipe 6 and the liner cover 4 can be integrally formed or separately formed and then assembled together.
[0069] Implementation method 4: Figure 3 and Figure 4As shown, the pot cover also includes a steam valve 5 and a lining cover 4 installed on the cover body, the steam valve 5 has a steam inlet and a steam outlet, the lining cover 4 is provided with an exhaust pipe 6 connected to the steam outlet, the exhaust pipe 6 passes through the exhaust port 14, the exhaust port 14 has a first section 142 and a second section 143 located inside the first section 142, a first insulation gap 144 is provided between the exhaust pipe 6 and the inner wall surface of the first section 142, a second insulation gap 145 is provided between the exhaust pipe 6 and the inner wall surface of the second section 143, and the radial dimension of the second insulation gap 145 is greater than the radial dimension of the first insulation gap 144. The radial dimension of the first thermal insulation gap 144 is relatively small, which can reduce the probability of external impurities entering the interior of the pot cover through the first thermal insulation gap 144, thereby forming effective protection for the components inside the pot cover. The radial dimension of the second thermal insulation gap 145 is relatively large, which can reduce the heat transfer from the exhaust pipe 6 to the IMD panel 1, thereby reducing the temperature rise of the IMD panel 1, and further reducing the probability of the decorative layer 12 warping or the decorative layer 12 separating from the substrate 11.
[0070] As a preferred embodiment of the fourth embodiment, the second section 143 has a flared structure with a gradually increasing inner diameter from the outside to the inside. This flared structure not only guides the exhaust pipe 6 during assembly with the exhaust port 14, improving lid assembly efficiency, but also further increases the second insulation gap 145 from the outside to the inside, thereby further reducing heat transfer from the exhaust pipe 6 to the IMD panel 1.
[0071] Implementation method five: Figure 3 and Figure 4 As shown, the pot lid also includes a steam valve 5 and a lining cover 4 mounted on the lid body. The steam valve 5 has a steam inlet and a steam outlet. The lining cover 4 is provided with a steam exhaust pipe 6 connected to the steam outlet. The steam exhaust pipe 6 passes through the steam exhaust port 14 and has a steam exhaust passage 62 connecting the steam outlet with the outside world, as well as a heat-insulating cavity 61 arranged around the steam exhaust passage 62. The heat-insulating cavity 61 at least partially overlaps with the axial projection of the substrate 11 along the steam exhaust pipe 6. The provision of the heat-insulating cavity 61 can reduce heat transfer from the steam exhaust pipe 6 to the IMD panel 1, thereby reducing the temperature rise of the IMD panel 1 and further reducing the probability of the decorative layer 12 warping or separation from the substrate 11.
[0072] As a preferred embodiment of the fifth embodiment, the insulation cavity 61 extends from the bottom of the exhaust pipe 6 to the upper part of the lining cover 4, so that when the high-temperature steam first enters the exhaust pipe 6, the insulation cavity 61 has an insulation effect on it, further reducing the heat transfer from the exhaust pipe 6 to the IMD panel 1.
[0073] Anything not described in this application can be achieved by adopting or drawing on existing technologies.
[0074] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
[0075] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
