Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to a lamp panel assembly and a cooking appliance. Background Technology

[0002] In some electric pressure cookers, the display panel is mounted on the cooker body. Since most cooker bodies are curved, the display panel mounted on this curved surface is fitted with a bracket, which also has a curved surface. The display panel itself is flat, and the LEDs on the panel located on the arched part of the bracket are farther from the front surface of the bracket, while the LEDs on the panel located at the edge of the bracket are closer to the front surface. This results in poor consistency and unevenness in the overall display effect across the front surface of the bracket.

[0003] To address the inconsistency in display quality, LEDs of varying heights are typically used. For example... Figure 1 As shown, a bracket 20' is provided on the body 30', a display light panel 10' is provided on the bracket 20', and multiple LED beads 13' are provided on the display light panel 10'. Multiple light-transmitting holes 21' are provided on the bracket 20', each corresponding to one of the multiple LED beads 13'. The height of the LED beads 13' located on the edge of the bracket 20' on the display light panel 10' is less than the height of the LED beads 13' located on the arched part of the bracket 20' on the display light panel 10'. In this way, the display effect of the multiple LED beads 13' at the same distance from the front surface of the bracket 20' in the multiple light-transmitting holes 21' can solve the problem of inconsistent display effect.

[0004] However, the different heights of the LED chips used result in higher costs. Utility Model Content

[0005] The main purpose of this utility model is to provide a lamp panel assembly and cooking appliance to solve the problem of high cost caused by the different heights of the lamp beads used in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a lamp panel assembly is provided, comprising: a planar lamp panel including a control board, a control chip, and multiple LED beads, wherein the control chip and multiple LED beads are all disposed on the control board, each LED bead having the same height, the control chip being controlled and connected to the multiple LED beads, and capable of independently controlling the brightness of each LED bead; and a curved support having multiple light-transmitting holes, wherein the multiple LED beads are inserted into the multiple light-transmitting holes one by one.

[0007] By applying the technical solution of this utility model, since each LED bead has the same height, LED beads of the same height can be used, reducing costs. Simultaneously, because the control chip can independently control the brightness of each LED bead, the brightness of LED beads farther from the front surface of the curved support is greater than that of LED beads closer to the front surface of the curved support, resulting in a consistent display effect on the front surface of the curved support and solving the problem of inconsistent display effects in the LED panel assembly. Therefore, the technical solution of this application can solve the problem of high costs caused by the use of LED beads of varying heights in related technologies.

[0008] Furthermore, a portion of the multiple light-transmitting holes constitutes a first hole group, located in the middle of the curved support. The remaining portion of the multiple light-transmitting holes constitutes a second hole group, located at the edge of the curved support. The brightness of the LEDs corresponding to the first hole group is greater than the brightness of the LEDs corresponding to the second hole group. In this way, even if the LEDs are of the same height, the consistency of the display effect of the lamp board assembly can be maintained through independent brightness control by the control chip.

[0009] Furthermore, there is a first distance between two adjacent LEDs corresponding to the first hole group, and a second distance between two adjacent LEDs corresponding to the second hole group, wherein the second distance is greater than or equal to the first distance. This optimizes the LED layout, ensures the brightness uniformity of the LED panel assembly, and improves the user's visual experience.

[0010] Furthermore, the curved support includes an arc-shaped plate and multiple lampshades disposed on the inner surface of the arc-shaped plate. Each lampshade corresponds to a specific LED chip, and the inner end faces of the lampshades are flush. Each light-transmitting hole is located inside a lampshade and extends through both the inner and outer surfaces of the arc-shaped plate. This design can control and guide the light emitted by the LED chips, reduce light scattering, improve light concentration and display effect, and the structure of the lampshades protects the LED chips.

[0011] Furthermore, the planar light panel also includes brightness adjustment buttons on the control panel. These buttons have multiple brightness levels, and the control chip adjusts the brightness of multiple LEDs based on the selected level. This allows users to adjust the overall brightness of the light panel assembly according to their needs or changes in ambient light. For example, dim LEDs can be brightened while bright LEDs are dimmed to achieve a uniform overall brightness, or all LEDs can be dimmed to put cooking appliances into a sleep state. This enhances the adaptability of the light panel assembly and improves the user experience.

[0012] Furthermore, the curved support can be circular or rectangular. This curved shape allows the light panel assembly to adapt to the shape of cooking utensils, improving its versatility and ease of installation.

[0013] Furthermore, the light panel also includes a trigger switch mounted on the control panel. When the trigger switch is activated, the corresponding LED light can turn on or off. This design enables the enabling or disabling of specified information or functions on the light panel assembly, improving the interactivity of the light panel assembly.

[0014] Furthermore, the height of each LED bead is greater than or equal to 1mm and less than or equal to 20mm. Limiting the height of each LED bead ensures consistency and replaceability during mass production and assembly, which helps reduce production costs and improve production efficiency.

[0015] Furthermore, the light panel assembly also includes a faceplate affixed to the curved support, with multiple identification marks on the faceplate, each corresponding to a specific light-transmitting hole. By assigning multiple identification marks to multiple light-transmitting holes, the function or information corresponding to the illuminated LED can be clearly displayed, improving the intuitiveness of user understanding and operation. At the same time, the faceplate also protects the curved support and LED from contamination such as dust and oil stains.

[0016] According to another aspect of the present invention, a cooking appliance is provided, including a housing and a lamp panel assembly disposed on the housing, wherein the lamp panel assembly is the lamp panel assembly described above. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] According to one aspect of this utility model, a lamp panel assembly is provided, such as... Figure 2 As shown, an embodiment of the lamp panel assembly includes a planar lamp panel 10 and a curved support 20. The planar lamp panel 10 includes a control board 11, a control chip 12, and multiple LED beads 13. The control chip 12 and the multiple LED beads 13 are all disposed on the control board 11. Each LED bead 13 has the same height. The control chip 12 is connected to the multiple LED beads 13 and can independently control the brightness of each LED bead 13. The curved support 20 is provided with multiple light-transmitting holes 21, and the multiple LED beads 13 are inserted into the multiple light-transmitting holes 21 one by one.

[0030] The technical solution of the embodiment of the lamp board assembly reduces costs because each LED bead 13 has the same height, allowing the use of LED beads 13 of the same height. Simultaneously, since the control chip 12 can independently control the brightness of each LED bead 13, adjusting the brightness of each LED bead 13 during operation, the brightness of LED beads 13 farther from the front surface of the curved support 20 is greater than that of LED beads 13 closer to the front surface of the curved support 20. This ensures a consistent display effect on the front surface of the curved support 20, solving the problem of inconsistent display effects in the lamp board assembly. Therefore, the technical solution of the embodiment of the lamp board assembly solves the problem of high costs caused by the use of LED beads of varying heights in related technologies. Furthermore, because each LED bead 13 has the same height, LED beads of the same specification can be used, avoiding easy assembly errors during the assembly process.

[0031] like Figure 2 As shown, a portion of the multiple light-transmitting holes 21 constitutes a first hole group, which is located in the middle of the curved support 20. The remaining portion of the multiple light-transmitting holes 21 constitutes a second hole group, which is located at the edge of the curved support 20. The brightness of the LEDs 13 corresponding to the first hole group is greater than the brightness of the LEDs 13 corresponding to the second hole group. In this way, even if the LEDs 13 have the same height, the consistency of the display effect of the lamp board assembly can be maintained through independent brightness control by the control chip 12.

[0032] like Figure 2 As shown, there is a first distance between two adjacent LED beads 13 corresponding to the first hole group, and a second distance between two adjacent LED beads 13 corresponding to the second hole group. The second distance is greater than or equal to the first distance. This optimizes the layout of the LED beads 13, ensures the brightness uniformity of the lamp panel assembly, and helps improve the user's visual experience.

[0033] like Figure 2 and Figure 3 As shown, the curved support 20 includes an arc-shaped plate 22 and multiple lamp covers 23 disposed on the inner surface of the arc-shaped plate 22. Each lamp cover 23 corresponds to a specific LED chip 13, and the inner end faces of the lamp covers 23 are flush. Each light-transmitting hole is located within a lamp cover 23 and extends through both the inner and outer surfaces of the arc-shaped plate 22. This design controls and guides the light emitted by the LED chips 13, reduces light scattering, and improves light concentration and display effect. Simultaneously, the structure of the lamp covers 23 protects the LED chips 13. The outer surface of the arc-shaped plate is the outer surface of the curved support 20.

[0034] like Figure 2As shown, the planar light panel 10 also includes brightness adjustment buttons on the control board 11. The brightness adjustment buttons have multiple levels, and the control chip 12 adjusts the brightness of multiple LED beads 13 according to the level of the brightness adjustment button. In this way, users can adjust the overall brightness of the light panel assembly by adjusting the brightness adjustment buttons according to actual needs or changes in ambient light. For example, dim LED beads can be brightened, and bright LED beads can be dimmed to achieve a consistent overall display brightness of the light panel assembly. Alternatively, they can all be dimmed to put cooking appliances into a sleep state, enhancing the adaptability of the light panel assembly and improving the user experience.

[0035] like Figure 2 As shown, the curved support 20 is rectangular in shape. The shape of the curved support 20 allows the light panel assembly to adapt to the shape of cooking utensils of corresponding shapes, improving the versatility and ease of installation of the light panel assembly.

[0036] It should be noted that the aforementioned non-standard geometric shapes, such as circles or rectangles, are similar shapes.

[0037] like Figure 2 As shown, the light panel 10 also includes a trigger switch 14 disposed on the control panel 11. When the trigger switch 14 is triggered, the corresponding LED bead 13 can light up or turn off. The above design enables the enabling or disabling of specified information or functions on the light panel assembly, improving the interactivity of the light panel assembly.

[0038] like Figure 2 As shown, the height of each LED bead 13 is greater than or equal to 1 mm and less than or equal to 20 mm. Limiting the height of each LED bead 13 ensures consistency and replaceability during mass production and assembly, which helps reduce production costs and improve production efficiency. Preferably, the height of each LED bead 13 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm.

[0039] like Figure 2 As shown, the lamp panel assembly also includes a faceplate 40 affixed to the curved bracket 20. The faceplate 40 has multiple identification marks, each corresponding to a specific light-transmitting hole 21. By assigning multiple identification marks to multiple light-transmitting holes 21, the function or information corresponding to the illuminated LED 13 can be intuitively displayed, improving the intuitiveness of user understanding and operation. Simultaneously, the faceplate 40 also protects the curved bracket 20 and the LED 13 from dust, oil stains, and other contaminants. Specifically, the faceplate 40 is affixed to the front surface of the curved bracket 20.

[0040] In this embodiment, the lamp bead 13 is an LED. The core of the LED is a PN junction semiconductor material. When a forward voltage is applied, electrons jump from the N region to the P region and recombine with holes, releasing energy in the form of photons, thus emitting light. The driving current is proportional to the brightness of the LED. Due to the curvature of the curved support 20, the distance between the lamp bead 13 and the surface mount 40 is not uniform, so the overall display effect varies greatly.

[0041] Typically, control chip 12 controls LED illumination using a scanning method. The current output from the I / O port of each control chip 12 is constant, resulting in consistent brightness across the LEDs after one scan. In this embodiment, control chip 12 incorporates constant current driving technology, using different currents to drive different LED beads 13, thus producing varying brightness levels. The I / O ports of control chip 12 can be enabled for SEG and COM functions, with SEG output current set to n levels (n>1). When an LED is far from the surface mount 40, a higher current level can be enabled on the corresponding I / O port's SEG function, increasing the brightness of the LED connected to that port and improving the consistency of the display through the surface mount.

[0042] According to another aspect of this application, a cooking appliance is provided. An embodiment of the cooking appliance includes a housing 30 and a light panel assembly disposed on the housing 30, the light panel assembly being the aforementioned light panel assembly. Because the aforementioned light panel assembly can solve the problem of high cost caused by the varying heights of the LEDs used in related technologies, the cooking appliance including this light panel assembly can solve various technical problems.

[0043] The cooking appliance also includes an inner pot housed within the casing 30 and a heating device disposed at the bottom of the inner pot. The heating device can be a heating plate, an IH coil, or an electric heating film. The heating device is connected to the control board 11 of the lamp panel assembly. The control board 11 can control the heating time and heating power of the heating device to enable the inner pot to perform different cooking functions.

[0044] The cooking appliance in this embodiment is an electric pressure cooker. Of course, in embodiments not shown in the figures, the pot body can also be a cup or an inner pot. The cooking appliance can also be a rice cooker, a low-pressure rice cooker, a soy milk maker, a food processor, a stir-fry machine, an electric slow cooker, a multi-functional pot, etc.

[0045] In the description of this utility model, it should be understood that "multiple" means a quantity of two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0047] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components.
