[0045] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0047] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0048] like Figures 1 to 5 As shown, the cooking appliance of the embodiment includes an operation panel 10 and a display assembly 20 disposed below the operation panel 10. The operation panel 10 includes an operation interface pattern, including a first operation interface pattern layer 30 and a second operation interface pattern layer 40 located below the first operation interface pattern layer 30.

[0049] Using the technical solution of this embodiment, the user interface pattern includes a first user interface pattern layer 30 and a second user interface pattern layer 40, with the first user interface pattern layer 30 positioned above the second user interface pattern layer 40. This structure positions the two user interface pattern layers at different heights, resulting in a visually distinct layering of the two patterns when displayed. This structure enriches the display options of the user interface panel and enhances the product's premium feel. Therefore, the technical solution of this embodiment solves the problem of the single-image display effect of display panels in existing cooking appliances.

[0050] Specifically, from Figure 5 As can be seen, in Example 1, the patterns in the first operation interface pattern layer 30 and the patterns in the second operation interface pattern layer 40 are offset. Specifically, the first operation interface pattern layer 30 includes the following patterns: "Quickly Debone Meat," "Adding Dishes Midway," "Steam Sterilization," "Pork Ribs," "Beef and Lamb," "Beef Brisket," "Soup," "Chicken and Duck," "Tendon," "Beans," "Waterless Baking," "Reservation," "Taste," "Fragrant Glutinous Rice," "Quick Cooking," "Multi-Grain Porridge," "White Rice Porridge," "Start," "Quick Vent," "Keep Warm / Cancel," and plus and minus signs. The second operation interface pattern layer 40 includes the following patterns: "Pre-order Cooking," "Time Remaining," "20," "30," "50," "70," "90," "108," "Hard," "Medium," "Soft," and a central area for displaying numbers. Furthermore, in this embodiment, the patterns in the first operation interface pattern layer 30 and the second operation interface pattern layer 40 are all offset, with the patterns in the first operation interface pattern layer 30 covering the patterns in the second operation interface pattern layer 40. In an embodiment not shown, the pattern of the first operation interface pattern layer 30 and the pattern of the second operation interface pattern layer 40 may also be staggered, partially overlapped, or completely overlapped.

[0051] like Figure 4 As shown, in the technical solution of embodiment 1, the operation panel 10 further includes a panel body 11, and the first operation interface pattern layer 30 is located on the front of the panel body 11. Specifically, the front of the panel body 11 refers to the surface of the panel body 11 facing the user.

[0052] like Figure 5 As shown, in the technical solution of Example 1, the first operation interface pattern layer 30 is formed on the front surface of the panel body 11 through a silk screen printing process, a hot stamping process, or a sticker process. Preferably, the first operation interface pattern layer 30 is formed on the front surface of the panel body 11 through a silk screen printing process. The silk screen printing process provides a good display effect of the first operation interface pattern layer 30. At the same time, this structure allows the first operation interface pattern layer 30 to be visible to the user even when it is not illuminated.

[0053] like Figure 4 As shown, in the technical solution of embodiment 1, the panel body 11 is made of a transparent or translucent material, and the second operation interface pattern layer 40 is located on the back of the panel body 11. Specifically, when the display component 20 is working, the display component 20 shines light on the second operation interface pattern layer 40, and causes the pattern thereon to be illuminated onto the panel body 11. Since the panel body 11 is made of a transparent or translucent material, the user can see the pattern of the second operation interface pattern layer 40 located below from above the panel body 11. When the display component 20 is not working, the user cannot see the pattern of the second operation interface pattern layer 40 from above the panel body 11, or can only see a very shallow outline of the pattern of the second operation interface pattern layer 40.

[0054] like Figure 4 As shown, in the technical solution of the first embodiment, the cooking appliance further includes a first membrane structure 50 disposed below the panel body 11 , and the second operation interface pattern layer 40 is formed on the first membrane structure 50 .

[0055] Specifically, if Figure 6 As shown, the first film structure 50 is a PET film. The first film structure 50 includes a first film body 53 and a first light-shielding layer 51. The first light-shielding layer 51 is printed on the first film body 53. A first light-transmitting area 52 is formed on the first light-shielding layer 51. The first light-transmitting area 52 forms the second operation interface pattern layer 40. Specifically, the first light-shielding layer 51 is printed on the first film body 53 through a printing process. At the same time, light cannot pass through the first light-shielding layer 51. A plurality of first light-transmitting areas 52 are provided on the first light-shielding layer 51. Light can pass through the first light-transmitting area 52 and illuminate the panel body 11. It should be noted that, Figure 6 The first light-transmitting area 52 shown in the figure is represented as a square frame, which is for reference only. In an actual product, the first light-transmitting area 52 may be a hollowed-out shape of the corresponding text. Figure 5 and Figure 6 , there are 13 first light-transmitting areas 52. The first light-transmitting area 52 in the larger area in the middle is the digital display area. The two first light-transmitting areas 52 above the digital display area are hollow patterns of "pre-set cooking" and "remaining time" respectively. The ten patterns in the lower part of the digital display area are hollow patterns of "20", "30", "50", "70", "90", "108", "hard", "moderate" and "soft". Since the first light-transmitting area 52 is a transparent area, the color of the light determines the color irradiated on the panel body 11.

[0056] Preferably, in the technical solution of Example 1, the first membrane structure 50 further includes a first diffusion layer disposed in the first light-transmitting region 52. Specifically, the first diffusion layer has a corresponding color; that is, when the light tube is illuminated, the color of the first diffusion layer determines the color of the illuminated panel body 11. Furthermore, different first light-transmitting regions 52 can be configured with diffusion regions of different colors, thereby making the second operation interface pattern layer 40 more colorful. The provision of the first diffusion layer enables a colorful display effect to be achieved even when display elements of the same color are used in the display assembly 20, thereby reducing product costs.

[0057] like Figure 4 Shown and Figure 7 As shown, in the technical solution of embodiment 1, the display component 20 includes a lamp holder 21 and a lamp board 22. The lamp holder 21 is arranged below the panel body 11, and the lamp board 22 is arranged below the lamp holder 21. The first membrane structure 50 is attached to the surface of the lamp holder 21 facing the panel body 11, and the lamp holder 21 is provided with a first light-transmitting hole 211. A first light-emitting element 221 is provided on the lamp board 22, and the first light-transmitting area 52, the first light-transmitting hole 211 and the first light-emitting element 221 are arranged in a one-to-one correspondence. Specifically, when the first light-emitting element 221 emits light, the light passes through the first light-transmitting hole 211 and the first light-transmitting area 52 and then irradiates the lamp tube on the panel body 11. Furthermore, from Figure 7 As can be seen, the first light-emitting element 221 includes a central, long, strip-shaped digital tube and LEDs on either side of the digital tube. The digital tube corresponds to the larger, central, first light-transmitting area 221. The LEDs correspond to the hollowed-out patterns for "pre-set cooking," "remaining time," "20," "30," "50," "70," "90," "108," "hard," "medium," and "soft," respectively.

[0058] like Figures 8 to 11 As shown, in the technical solution of the first embodiment, a recessed portion 212 is provided on the surface of the lamp holder 21 facing the panel body 11. The first light-transmitting hole 211 is disposed within the recessed portion 212, and the first membrane structure 50 is attached to the bottom wall of the recessed portion 212. Specifically, the shape of the bottom wall of the recessed portion 212 matches the shape of the first membrane structure 50. The recessed portion 212 facilitates positioning of the first membrane structure 50 and facilitates the attachment operation of the first membrane structure 50.

[0059] like Figures 8 to 11As shown, in the technical solution of embodiment 1, a first light-collecting tube 213 is provided on the surface of the lamp holder 21 facing the lamp board 22, and the first light-collecting tube 213 is provided corresponding to the first light-transmitting hole 211. Specifically, the light-collecting tube enables the light of the corresponding first light-emitting element 221 to be concentrated and irradiated within the corresponding first light-transmitting area 52. And prevents the occurrence of light crosstalk and light leakage. Furthermore, there are a total of 13 first light-collecting tubes 213 in this embodiment. In order to ensure structural strength, the side walls of adjacent first light-collecting tubes 213 are connected together. Of course, adjacent first light-collecting tubes 213 can also be provided separately, that is, there is no mutual connection between adjacent first light-collecting tubes 213.

[0060] like Figure 4 Shown and Figure 7 As shown, in the technical solution of the first embodiment, the lamp holder 21 further includes a second light-transmitting hole 214, the lamp board 22 includes a second light-emitting element 222, the second light-transmitting hole 214 is located in the area of ​​the first operation interface pattern layer 30, and the second light-transmitting hole 214 and the second light-emitting element 222 are correspondingly arranged. Specifically, the second light-emitting element 222 in the first embodiment serves as a selection indicator light. Specifically, from Figure 5 As can be seen, the patterns in the first operation interface pattern layer 30 all consist of a frame structure and text within the frame structure. The second light-transmitting hole 214 is located within the frame structure, above the text portion. When the user selects or operates on a pattern, the corresponding second light-emitting element 222 illuminates, and the light shines through the second light-transmitting hole 214 onto the panel body 11, prompting the user that the current icon has been operated or selected.

[0061] like Figure 5 Shown and Figure 7 As shown, in the technical solution of Example 1, a selection pattern 60 is provided within the area of ​​the first operation interface pattern layer 30, and a touch sensor 70 is provided between the light board 22 and the light frame 21 at a position corresponding to the selection pattern 60. Specifically, the aforementioned frame structure and the text within the frame structure form the selection pattern 60. The touch sensor 70 transmits the user's touch operation to the circuit board of the light board 22. Simultaneously, the control device controls the corresponding second light-emitting element 222 to illuminate.

[0062] Furthermore, the selection pattern 60 may also be provided on the second operation interface pattern layer 40 , or the selection pattern 60 may be provided on both the first operation interface pattern layer 30 and the second operation interface pattern layer 40 .

[0063] Preferably, the touch sensing element 70 is a spring.

[0064] like Figure 5 Shown and Figure 7As shown, in the technical solution of the first embodiment, the selection pattern 60 is provided in the region of the first operation interface pattern layer 30 , and the second light-transmitting hole 214 is located outside the touch sensing element 70 .

[0065] like Figures 8 to 11 As shown, in the technical solution of embodiment one, a second light-concentrating tube 215 is provided on the surface of the lamp holder 21 facing the lamp panel 22, and the selection pattern 60 and the touch-sensing element 70 are both located in the second light-concentrating tube 215. Specifically, the function of the second light-concentrating tube 215 is similar to that of the first light-concentrating tube 213. However, the difference between the second light-concentrating tube 215 and the first light-concentrating tube 213 is that the second light-concentrating tube 215 includes a small arc segment and a large arc segment that are connected to each other. The above structure makes the second light-concentrating tube 215 have a gourd shape. Among them, the large arc segment is used to position the spring, and the small arc segment is arranged corresponding to the second light-emitting element 222. In this embodiment, the large arc segment and the small arc segment are connected to each other. Of course, in order to achieve a better focusing effect, the large arc segment and the small arc segment can also be separated by a retaining rib. In embodiment one, there is no connection between adjacent second light-concentrating tubes 215.

[0066] Preferably, the cooking appliance in the first embodiment is an electric pressure cooker or an electric rice cooker. Of course, the above-mentioned operation panel 10 can also be applied to other cooking appliances.

[0067] from Figures 1 to 4 As can be seen, in the technical solution of Example 1, the cooking appliance further includes: a pot body 80 for holding food to be cooked; a pot lid 90, which is disposed on the pot body 80, and an operation panel 10 disposed on the pot lid 90. Furthermore, the pot lid 90 includes an inner lining and a surface cover 91 disposed on the inner lining, the surface cover 91 being provided with a receiving recess 92, the display assembly 20 being disposed in the receiving recess 92, and the panel body 11 being disposed on the surface cover and covering the opening of the receiving recess 92.

[0068] like Figure 12 As shown, in the technical solution of Example 1, a connecting structure 100 is provided on the surface of the panel body 11 facing the cover 91. The panel body 11 is connected to the cover 91 via the connecting structure 100. Specifically, the connecting structure 100 is a screw post, and the cover 91 is provided with a connecting hole. The cooking appliance also includes connecting screws, which are respectively inserted into the connecting hole and the screw post to secure the panel body 11 to the cover 91.

[0069] like Figure 13As shown, the difference between the second embodiment of the cooking appliance of the present application and the first embodiment is that the operation panel 10 further includes a panel body 11 and a second membrane structure 12. The panel body 11 is made of a transparent or translucent material; the second membrane structure 12 is arranged on the panel body 11. In the technical solution of the second embodiment, the arrangement of the first operation interface pattern layer 30 and the second operation interface pattern layer 40 is more flexible than that of the first embodiment. Specifically, the first operation interface pattern layer 30 and the second operation interface pattern layer 40 include the following arrangement methods:

[0070] The first operation interface pattern layer 30 can be formed on the second membrane structure 12 by a silk screen process, a hot stamping process, or a sticker process. Specifically, the first operation interface pattern layer 30 is provided on the upper surface or the lower surface of the second membrane structure 12.

[0071] The second operation interface pattern layer 40 can be formed on the second membrane structure 12 by a silk screen process, a hot stamping process, or a sticker process. Specifically, the second operation interface pattern layer 40 is provided on the upper surface or the lower surface of the second membrane structure 12.

[0072] Furthermore, similar to the first embodiment, the first operation interface pattern layer 30 can be formed on the upper surface or the lower surface of the panel body 11 by a silk screen process, a hot stamping process or a sticker process.

[0073] Furthermore, similar to the first embodiment, the second operation interface pattern layer 40 can be formed on the upper surface or the lower surface of the panel body 11 by a silk screen process, a hot stamping process or a sticker process.

[0074] like Figure 12 As shown, in the technical solution of Example 2, the second membrane structure 12 is disposed on the front or back side of the panel body 11. The second membrane structure 12 includes a second membrane body 121, a second light-shielding layer 122, and a second diffusion layer 123. The second membrane body 121 is made of a transparent material. The second light-shielding layer 122 and the second diffusion layer 123 are both printed on the back side of the second membrane body 121. A second light-transmitting area 124 is formed on the second light-shielding layer 122, and the position of the second diffusion layer 123 corresponds to the second light-transmitting area 124. The functions of the second light-shielding layer 122 and the second diffusion layer 123 are similar to those of the first light-shielding layer 51 and the first diffusion layer, and are not further described here.

[0075] Furthermore, the second light-transmitting area 124 forms the first operation interface pattern layer 30 or the second operation interface pattern layer 40 .

[0076] In the second embodiment, under the condition that the first operation interface pattern layer 30 is located on the front of the panel body 11 and the second operation interface pattern layer 40 is located below the panel body 11, those skilled in the art can adjust the position of the second membrane body 121 on the panel body 11 (so that the second membrane body 121 is set above the panel body 11, or so that the second membrane body 121 is set below the panel body 11). At the same time, the setting position of the first operation interface pattern layer 30 and the setting position of the second operation interface pattern layer 40 can be arbitrarily combined in the above settings. The following are a few examples to illustrate:

[0077] When the second membrane body 121 is disposed above the panel body, the first operation interface pattern layer 30 can be disposed on the second membrane body 121 by silk screen printing. The second operation interface pattern layer 40 is disposed on the lower surface of the panel body 11 by silk screen printing.

[0078] When the second film body 121 is disposed below the panel body, the first operation interface pattern layer 30 can be disposed on the upper surface 11 of the panel body by a silk screen process. The second operation interface pattern layer 40 is formed by the second light-transmitting area 124 .

[0079] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0080] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures".
