Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of kitchen appliances, and in particular to a digital display device and a cooking appliance. BACKGROUND
[0002] The existing cooking appliance with a digital tube display screen, such as an electric rice cooker, generally includes a circuit board with a digital tube, a mounting bracket, and a display board film. Generally, information is displayed on the digital tube directly through a semi-transparent rectangular film frame. However, the digital tube display has a film, and the display board film is outside the whole machine, resulting in a large number of films, multiple production and manufacturing processes, and high material costs.
[0003] To solve the above problems, in the related art, a digital model is made on the mounting bracket by opening a mold, and light is divided by the mold model to present information to consumers, thereby canceling the film on the digital tube. However, in the scheme of making a digital model on the mounting bracket by opening a mold, the light needs to pass through the open model on the mounting bracket, and the edges of the light have burrs, resulting in poor display effect. Moreover, the open model on the mounting bracket needs to be designed with a 0.8mm or so plug-in rib on the mold, resulting in low mold strength and easy damage to the mold during the manufacturing process. CONTENT OF THE UTILITY MODEL
[0004] To solve the above technical problems or at least partially solve the above technical problems, the present application provides a digital display device and a cooking appliance to ensure clear digital display effect and improve the strength of the mold for producing and manufacturing the mounting bracket.
[0005] The first aspect of the present application provides a digital display device, including a circuit board, a mounting bracket, and a display board film. The circuit board is provided with a light source. The mounting bracket is formed with a hollow area corresponding to the light source. The display board film is arranged on the side surface of the mounting bracket away from the circuit board. The hollow area has a plurality of hollow holes, and the plurality of hollow holes are configured as a digital model.
[0006] The display board film is formed with a light-transmitting digital display pattern at the position corresponding to the hollow area. The digital display pattern includes a plurality of light-transmitting pattern segments. The plurality of pattern segments correspond one-to-one to the plurality of hollow holes, and the light-transmitting area of the pattern segment is smaller than the hollow area of the corresponding hollow hole, so as to shield the edge of the hollow hole.
[0007] In some embodiments, the display board film includes an appearance layer and a covering layer.
[0008] The appearance layer is formed with a perspective window at the position corresponding to the hollow area. The covering layer is arranged on the side surface of the perspective window facing the mounting bracket. The covering layer is formed with the digital display pattern.
[0009] In some embodiments, the display panel film further includes a matte layer disposed on the surface of the cover layer facing away from the outer layer.
[0010] In some embodiments, the display panel film includes an outer layer that covers the cutout area, and the outer layer has a light-transmitting digital display pattern formed at a location corresponding to the cutout area.
[0011] In some embodiments, the surface of the outer layer facing away from the mounting bracket is colored the same.
[0012] In some embodiments, the display panel film further includes a matte layer disposed on the surface of the outer layer facing the mounting bracket and located at a position corresponding to the cutout area.
[0013] In some embodiments, the light source includes a plurality of light-emitting elements, each of which corresponds to a plurality of hollow holes, and the plurality of light-emitting elements are configured into a digital shape.
[0014] In some embodiments, the surface of the mounting bracket facing the film applied to the display panel is a plane;
[0015] Alternatively, the surface of the mounting bracket facing the film on the display panel may be curved.
[0016] In some embodiments, the display panel film is provided with a function menu and buttons;
[0017] The circuit board is provided with a first LED corresponding to the function menu and a second LED corresponding to the button. The mounting bracket is provided with a first cutout corresponding to the first LED and a second cutout corresponding to the second LED.
[0018] A second aspect of this application provides a cooking utensil, including an utensil body and a lid, the lid being closable on the utensil body, and further including a digital display device as described in any of the above embodiments, the digital display device being disposed on one of the utensil body and the lid.
[0019] The technical solution provided in this application has at least the following advantages compared with the prior art:
[0020] 1. The digital display device provided in this application has a light source on a circuit board, a hollow area corresponding to the light source formed on a mounting bracket, and a light-transmitting digital display pattern formed on a display panel film at the location corresponding to the hollow area. With this configuration, the light emitted from the light source can pass through the hollow area on the mounting bracket and through the digital display pattern on the display panel film for digital display, thereby achieving a digital display effect. Furthermore, the hollow area has multiple hollow holes that form a digital shape, and the digital display pattern includes multiple light-transmitting pattern segments, each corresponding to a hollow hole, with the light-transmitting area of each pattern segment being smaller than the corresponding hollow hole. The perforated area of the mounting bracket allows light to pass through the digital display pattern on the display panel film, which can then shield the edges of the perforated area, ensuring a clear display and preventing issues such as rough edges on the light source, unclear digital outlines, and poor display quality caused by rough edges on the mounting bracket. Furthermore, since light passes through the digital display pattern on the display panel film, the perforated area of the mounting bracket can be appropriately enlarged. This increases the strength of the mold used to manufacture the mounting bracket, preventing damage to the mold during manufacturing.
[0021] 2. By setting the display panel film to include an outer layer and a cover layer, the outer layer forms a viewing window corresponding to the cutout area, and the cover layer is located on the side of the viewing window facing the mounting bracket. A light-transmitting digital display pattern is formed on the cover layer, so that other areas of the cover layer are opaque, and only the digital display pattern is light-transmitting. In this way, the non-opaque area of the cover layer can be used to block light, and only the digital display pattern can be light-transmitting, thereby achieving a digital display effect.
[0022] 3. By setting the display panel film to include a matte layer, which is placed on the side of the cover layer facing away from the outer layer, the light can be atomized, thereby making the transmitted light more uniform and presenting a better digital display effect.
[0023] 4. By setting the display panel film to include an outer layer that covers the cutout area, and forming a light-transmitting digital display pattern at the corresponding cutout area, a cover layer can be eliminated, resulting in fewer layers of display panel film and easier processing and manufacturing. Furthermore, at the corresponding cutout area, the non-light-transmitting area of the outer layer can be used to block light, allowing light to pass through only at the digital display pattern, thereby achieving a digital display effect.
[0024] 5. By making the surface of the outer layer the same color as the mounting bracket, the appearance of the outer layer can be made holographic, hiding the digital display area and making the appearance of the digital display device better. Attached Figure Description

[0034] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0035] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0036] Some embodiments of this application provide a digital display device that can be applied to cooking appliances, such as rice cookers, electric pressure cookers, and induction cookers. Of course, this digital display device can also be applied to other electrical products with digital display functions, such as refrigerators, washing machines, air conditioners, water heaters, range hoods, and microwave ovens.
[0037] Reference Figures 1 to 4 As shown, some embodiments of this application provide a digital display device 100, including a circuit board 1, a mounting bracket 2, and a display panel film 3.
[0038] The circuit board 1 is provided with a light source 11, and the mounting bracket 2 is formed with a hollow area 21 corresponding to the light source 11. The display panel film 3 is provided on the side surface of the mounting bracket 2 facing away from the circuit board 1, and the display panel film 3 forms a light-transmitting digital display pattern (not shown) at the location corresponding to the hollow area 21.
[0039] In other words, the display panel film 3 is transparent at the digital display pattern area, but opaque around the digital display pattern. Thus, when the light emitted by the light source 11 passes through the cutout area 21 on the mounting bracket 2 and shines on the digital display pattern on the display panel film 3, digital display can be achieved through the digital display pattern on the display panel film 3, thereby realizing the digital display effect.
[0040] The digital display device 100 provided in this application embodiment has a light source 11 on the circuit board 1, a hollow area 21 corresponding to the light source 11 is formed on the mounting bracket 2, and a light-transmitting digital display pattern is formed on the display panel film 3 at the location corresponding to the hollow area 21. With this configuration, the light emitted by the light source 11 can pass through the hollow area 21 on the mounting bracket 2 and be digitally displayed through the digital display pattern on the display panel film 3, thereby achieving a digital display effect. This setup offers several advantages. First, compared to displaying information directly on the digital tube using a semi-transparent rectangular film frame, it eliminates the need for a film frame on the light source 11 of the circuit board 1, thus reducing the number of films required, simplifying manufacturing processes, and saving material costs. Second, compared to creating digital shapes using a mold on the mounting bracket 2, light can pass through the digital display pattern on the display panel film 3 for digital display, ensuring a clear display effect and avoiding problems such as rough edges on the light source and unclear digital outlines caused by the rough edges of the mounting bracket 2, resulting in poor display quality. Furthermore, since light passes through the digital display pattern on the display panel film 3 for digital display, the cutout area 21 on the mounting bracket 2 can be appropriately enlarged, thereby increasing the strength of the mold used to manufacture the mounting bracket 2 and preventing damage to the mold during manufacturing.
[0041] In some embodiments, refer to Figure 2 and Figure 4 As shown, the hollow area 21 has multiple hollow holes 211, which together form a digital shape. In other words, a hollow area 21 with a digital shape is formed on the mounting bracket 2.
[0042] This configuration allows the light emitted from the light source 11 to pass through the hollow area 21 of the mounting bracket 2, forming a digital display effect. Then, the digital display pattern on the display panel film 3 is displayed more clearly, thus ensuring a better display effect. In addition, compared to forming a larger hollow hole 211 on the mounting bracket 2, the adhesion strength of the display panel film 3 at the hollow area 21 of the mounting bracket 2 can be improved, thereby ensuring the overall structural strength of the digital display device 100.
[0043] In some embodiments, the light-transmitting area of the digital display pattern is smaller than the cutout area 21 of the digital design. This arrangement facilitates the processing of the cutout area 21 of the digital design on the mounting bracket 2 and avoids ghosting in the digital display caused by processing errors of the mounting bracket 2 and the display panel film 3, thereby ensuring the digital display effect.
[0044] In some embodiments, the digital display pattern includes multiple light-transmitting pattern segments, each corresponding to a plurality of cutout holes 211. The light-transmitting area of the pattern segment is smaller than the cutout area of the corresponding cutout hole 211, thus shielding the edge of the cutout hole 211. In this way, when light passes through the digital display pattern on the display panel film 3 for digital display, the digital display pattern on the display panel film 3 can shield the edge of the cutout hole 211, thereby ensuring a clear display effect and avoiding the problem of rough edges on the light source and unclear digital outlines caused by the rough edges of the mounting bracket 2, resulting in a poor display effect.
[0045] In addition, since the light passes through the digital display pattern on the display panel film 3 for digital display, the cutout hole 211 on the mounting bracket 2 can be made appropriately large. The light emitted by the light source 11 passes through the relatively large cutout hole 211 on the mounting bracket 2 and then passes through the relatively small pattern segment on the display panel film 3 for light transmission.
[0046] This design can correspondingly increase the strength of the mold used to manufacture the mounting bracket 2, preventing damage to the mold during the manufacturing process. Furthermore, since the hollow area of the cutout hole 211 is the same as the light-transmitting area of the corresponding pattern segment, it can avoid ghosting caused by processing errors of the mounting bracket 2 and the display panel film 3, thereby better ensuring the digital display effect.
[0047] In practical implementation, the mounting bracket 2 is usually an injection molded part. The hollowed-out holes on the mounting bracket 2 are relatively narrow strip holes. In order to process the hollowed-out holes on the mounting bracket 2, relatively narrow (generally about 0.8mm) insert ribs need to be designed on the injection mold, resulting in low mold strength and easy damage to the mold during manufacturing. However, by adopting the above embodiment of this application, the width of the hollowed-out holes can be appropriately increased. Correspondingly, the width of the insert ribs on the injection mold can also be appropriately increased, for example, increased to about 1.0mm, or increased to about 1.2mm. This can improve the structural strength of the injection mold and avoid damage to the mold during the manufacturing of the mounting bracket 2.
[0048] In some embodiments, refer to Figures 1 to 4 As shown, in order to ensure the display effect of the digital display device 100, the light source 11 on the circuit board 1 can be a digital tube.
[0049] In some embodiments, refer to Figure 2 and Figure 4 As shown, the hollow area 21 has multiple hollow holes 211, which form a digital shape; the light source 11 includes multiple light-emitting elements 111, which correspond one-to-one with the multiple hollow holes 211, and the multiple light-emitting elements 111 form a digital shape.
[0050] This configuration ensures that the light emitted by the multiple light-emitting elements 111 passes through the corresponding perforations 211 and illuminates the digital display pattern on the display panel film 3. This guarantees the uniformity of the light illuminating the digital display pattern, thereby ensuring a more uniform brightness display effect.
[0051] In a specific implementation, the light-emitting element 111 can be a light-emitting diode (LED), and multiple LEDs can be packaged together to form an "8"-shaped device. The light source 11 can include several (e.g., four) "8"-shaped devices; it can also include a decimal point, colon, or vertical line between two adjacent "8"-shaped devices. In this embodiment, the light source 11 can also be called an LED digital tube.
[0052] In some embodiments, refer to Figure 1 and Figure 2 As shown, the display panel film 3 includes an outer layer 31 and a cover layer 32. The outer layer 31 has a viewing window 311 formed at a position corresponding to the cutout area 21, and the cover layer 32 is disposed on the side surface of the viewing window 311 facing the mounting bracket 2, and a light-transmitting digital display pattern is formed on the cover layer 32.
[0053] It should be understood that the surface of the outer layer 31 facing away from the mounting bracket 2 is the outer surface, which can also be called the front surface of the outer layer 31, and the surface of the outer layer 31 facing away from the mounting bracket 2 can be called the back surface of the outer layer 31. The cover layer 32 is provided on the surface of the viewing window 311 facing the mounting bracket 2, that is, the cover layer 32 is provided on the back surface of the viewing window 311.
[0054] By setting a cover layer 32 on the back of the viewing window 311 and forming a light-transmitting digital display pattern on the cover layer 32, that is, other areas of the cover layer 32 are opaque, and only the digital display pattern is light-transmitting, the non-light-transmitting area of the cover layer 32 can be used to block light, and only the digital display pattern is light-transmitting, thereby achieving a digital display effect.
[0055] In a specific implementation, the cover layer 32 can be a completely black layer, on which a translucent digital display pattern is formed. Thus, when the light source 11 is not lit, no trace of the digital display pattern is displayed on the front side of the display panel film 3, resulting in a better visual effect. Specifically, the cover layer 32 can be formed on the back side of the outer layer 31 by printing.
[0056] In some embodiments, continue to refer to Figure 1 and Figure 2 As shown, the display panel film 3 also includes a matte layer 33, which is disposed on the surface of the cover layer 32 facing away from the outer appearance layer 31. That is, the cover layer 32 is first disposed on the back side of the outer appearance layer 31, and then the matte layer 33 is disposed on the cover layer 32. The matte layer 33 can also be called a fogging layer.
[0057] With this configuration, the light emitted by the light source 11 can be atomized after passing through the matte layer 33, resulting in more uniform light transmission and a better digital display effect. Specifically, the matte layer 33 can be formed on the surface of the cover layer 32 facing away from the outer layer 31 by printing.
[0058] It should be noted that, in specific implementation, the matte layer 33 and the cover layer 32 can also be interchanged. Specifically, it is also feasible to first set the matte layer 33 on the back of the perspective window 311 of the appearance layer 31, and then set the cover layer 32 on the matte layer 33.
[0059] In some embodiments, in order to improve the appearance of the display panel film 3, an ink layer can be sprayed on the front side (i.e., the appearance surface) of the appearance layer 31; in order to protect the display panel film 3 and prevent the display panel film 3 from being worn, a transparent protective film can also be provided on the outside of the ink layer.
[0060] In other embodiments, reference is made to Figure 3 and Figure 4As shown, the display panel film 3 includes an outer layer 31, which covers the hollow area 21, and the outer layer 31 forms a light-transmitting digital display pattern at the location corresponding to the hollow area 21.
[0061] In other words, compared to the solution with a perspective window 311 on the outer layer 31, this embodiment eliminates the perspective window 311 on the outer layer 31. On the outer layer 31, at the location corresponding to the hollow area 21, the area other than the light-transmitting digital display pattern is made opaque. That is, the outline of the digital display pattern is directly made on the outer layer 31.
[0062] This configuration eliminates the need for a cover layer 32, resulting in fewer layers of the display panel film 3 and simplifying manufacturing. Furthermore, this configuration allows light to be blocked by the opaque area of the outer layer 31 at the location corresponding to the cutout area 21, enabling light to pass through only the digital display pattern, thus achieving the desired digital display effect.
[0063] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, the surface of the outer layer 31 facing away from the mounting bracket 2 is set with the same color.
[0064] It should be understood that the surface of the outer layer 31 facing away from the mounting bracket 2 is the outer surface, which can also be called the front surface of the outer layer 31, and the surface of the outer layer 31 facing away from the mounting bracket 2 can be called the back surface of the outer layer 31. The surface of the outer layer 31 facing away from the mounting bracket 2 is made of the same color, that is, the front surface (i.e., the outer surface) of the outer layer 31 is made of the same color.
[0065] In other words, the front of the outer layer 31 and the corresponding area of the cutout area 21 on the mounting bracket 2 are treated with the same color as other parts of the outer layer 31. There is no need to set a perspective window 311 on the outer layer 31 corresponding to the cutout area 21 for digital display. With this setting, the appearance of the outer layer 31 can have a holographic effect, hiding the digital display area and making the appearance of the digital display device 100 more visually appealing.
[0066] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, the display panel film 3 also includes a matte layer 33, which is disposed on the surface of the outer layer 31 facing the mounting bracket 2 and located at the position corresponding to the cutout area 21. That is, the matte layer 33 is disposed on the back side of the outer layer 31. The matte layer 33 can also be called a fogging layer.
[0067] With this configuration, the light emitted by the light source 11 can be atomized after passing through the matte layer 33, resulting in more uniform light transmission and a better digital display effect. Specifically, the matte layer 33 can be formed on the back of the outer layer 31 by printing.
[0068] In some embodiments, in order to improve the appearance of the display panel film 3, an ink layer can be sprayed on the front side (i.e., the appearance surface) of the appearance layer 31; in order to protect the display panel film 3 and prevent the display panel film 3 from being worn, a transparent protective film can also be provided on the outside of the ink layer.
[0069] In some embodiments, the surface of the mounting bracket 2 facing the display panel film 3 is flat. Accordingly, the display panel film 3 is a flat film attached to the mounting bracket 2.
[0070] In other embodiments, reference is made to Figure 2 and Figure 4 As shown, the surface of the mounting bracket 2 facing the display panel film 3 is an arc-shaped surface 22. Correspondingly, the display panel film 3 is an arc-shaped film attached to the mounting bracket 2.
[0071] In practice, the shape of the mounting bracket 2 can be reasonably set according to the product's design requirements so that the appearance of the display panel film 3 fits the product's design requirements better.
[0072] It should be noted that the digital display device 100 provided in this application embodiment is not limited to digital display, but can also display other functions as needed.
[0073] For example, refer to Figure 2 and Figure 4 As shown, the display panel film 3 can be equipped with a function menu and a button section. The circuit board 1 can be equipped with a first LED 12 corresponding to the function menu and a second LED 13 corresponding to the button section. Correspondingly, the mounting bracket 2 can be equipped with a first cutout portion 23 corresponding to the first LED 12 and a second cutout portion 24 corresponding to the second LED 13. The first LED 12 can illuminate the function menu through the first cutout portion 23, and the second LED 13 can illuminate the button section through the second cutout portion 24.
[0074] Reference Figure 5 As shown, some other embodiments of this application provide a cooking appliance, including an appliance body 200 and a lid 300, the lid 300 being closable and covering the appliance body 200. The cooking appliance also includes a digital display device 100 as described in any of the above embodiments, the digital display device 100 being disposed on one of the appliance body 200 and the lid 300.
[0075] The cooking appliance provided in this application includes the digital display device 100 of any of the above embodiments, and therefore has the beneficial effects of the digital display device 100 of any of the above embodiments, which will not be repeated here.
[0076] In some embodiments, refer to Figure 5As shown, an installation opening is formed on the appliance body 200, and the digital display device 100 is installed at the installation opening.
