Technical Field

[0001] The present invention relates to air conditioning technology, in particular to a panel assembly and an air-conditioning indoor unit having the same. Background Art

[0002] With the continuous development and advancement of technology, household air conditioners are becoming increasingly intelligent, offering a wide range of functions. Most air conditioners currently on the market are equipped with ultraviolet sterilization modules, which effectively destroy the DNA or RNA of bacteria and viruses, achieving the purpose of sterilization and disinfection. However, ultraviolet rays can also damage human cells. To prevent harm to the human body, air conditioners with ultraviolet sterilization modules currently on the market generally conceal the UV lamp inside the unit to avoid UV exposure to the human body.

[0003] However, the ultraviolet lamps in the air conditioners currently on the market are hidden, resulting in the problem that the ultraviolet sterilization function of the air conditioner is invisible. Users have doubts about whether the sterilization function is operating normally during use, and the user experience is poor. Summary of the Invention

[0009] In order to achieve the above object, according to a first aspect of the present invention, the present invention provides a panel assembly, comprising:

[0010] a panel having at least one transparent area; and

[0011] The sterilization module is arranged on the panel, and a light-emitting device is provided on the side facing the panel, which is used to emit light to the transparent area after the sterilization module is started to show the working status of the sterilization module.

[0014] Furthermore, the transparent area includes a through hole opened on the panel, a transparent material installed in the through hole, and a photochromic coating coated on the surface of the transparent material, and the photochromic coating displays a preset color under ultraviolet light.

[0015] Furthermore, the wavelength of the ultraviolet light emitted by the ultraviolet irradiation unit is in the range of 100 to 280 nanometers; and

[0016] The transparent material is UV resistant.

[0017] Furthermore, the through hole and the transparent material are respectively in the shape of rings with the same diameter.

[0018] Furthermore, the through hole and the transparent material are installed and fixed in a snap-fit ​​manner.

[0019] Furthermore, a plurality of transparent areas are provided on the panel, the light emitting device includes a plurality of ultraviolet sterilization units, and the plurality of ultraviolet sterilization units and the plurality of transparent areas are provided in a one-to-one correspondence, and each transparent area is configured to display a preset color under the irradiation of ultraviolet light emitted by the corresponding ultraviolet sterilization unit; and

[0020] The plurality of ultraviolet sterilization units are configured to activate a preset number of ultraviolet sterilization units according to the sterilization intensity of the sterilization module, so that the number of transparent areas displaying preset colors is different under different sterilization intensities.

[0021] Furthermore, a transparent area is provided on the panel, and the transparent area is configured to display different preset colors under the irradiation of ultraviolet light of different intensities; and

[0022] The light emitting device is configured to adjust the intensity of the emitted ultraviolet light according to the sterilization intensity of the sterilization module, so that the transparent area displays different colors under different sterilization intensities.

[0023] Furthermore, the ratio of the area of ​​the transparent region to the area of ​​the panel is 0.01 to 0.1.

[0024] Furthermore, at least one ultraviolet sterilization unit is provided on the side of the sterilization module away from the panel, which is used to emit ultraviolet light in the direction away from the panel after the sterilization module is started to sterilize the inside of the device where the panel assembly is located.

[0025] Furthermore, the sterilization module includes a lamp holder, which is mounted on the panel; and

[0026] The light emitting device comprises ultraviolet lamp beads which are arranged on a side of a lamp frame facing the panel.

[0027] According to a second aspect of the present invention, the present invention further provides an air conditioner indoor unit, comprising:

[0028] a casing in which a heat exchanger and an air duct are disposed; and

[0029] The panel assembly of any of the above solutions is arranged on the casing, and the sterilization module is arranged on a side of the panel close to the heat exchanger and the air duct to sterilize the heat exchanger and the air duct.

[0030] The panel assembly of the present invention includes a panel and a sterilization module.

By adding a photochromic function to the transparent area, the panel assembly of the present invention realizes that after the sterilization module is activated, a local area of ​​the panel directly displays a preset color, preventing the problem of unclear light from the transparent area after the sterilization module is activated due to external factors such as the user's undesirable viewing angle and the indoor environment being too bright, thereby improving the adequacy of displaying the working status of the sterilization module, thereby improving the accuracy of the visualization of the sterilization function, and further enhancing the user experience.

[0032] Furthermore, the UV light emitted by the UV irradiation unit of the present invention has a wavelength range of 100 to 280 nanometers. This wavelength range provides excellent sterilization effectiveness but relatively low penetration, reducing the risk of UV light passing through the transparent area and into the room, potentially posing a health hazard. Furthermore, the transparent material used in the transparent area of ​​the present invention is UV-resistant, reducing the risk of UV light passing through the transparent area and further minimizing the risk of UV light posing a health hazard. This ensures visual sterilization without causing harm to the human body, thereby enhancing the safety of the visual sterilization function and improving the user experience.

[0040] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present invention to those skilled in the art.

[0041] To solve at least one of the above technical problems, an embodiment of the present invention provides a panel assembly and an air conditioner indoor unit having the same.

[0042] Figure 1 FIG is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention. Figure 1 As shown, the air conditioner indoor unit 1 of the present invention may generally include a casing 20 and a panel assembly 10 .

[0043] In this embodiment, a heat exchanger (not shown) and an air duct (not shown) are provided within the housing 20. After the indoor air enters the air duct from the air inlet, it exchanges heat through the heat exchanger and is then blown out through the air outlet 21 to regulate the indoor temperature.

[0044] like Figure 1 As shown, the panel assembly 10 is arranged on the housing 20. Specifically, the panel assembly 10 is arranged on the front side of the housing 20, and its lower edge and the housing 20 together define an air outlet 21. The panel assembly 10 includes a panel 100 and a sterilization module ( Figure 1 not shown).

[0045] Specifically, the sterilization module is located on the side of the panel 100 near the heat exchanger and air duct to sterilize these areas, effectively reducing the bacterial content in the airflow after heat exchange. Furthermore, the sterilization module is located on the inner side of the panel 100, that is, on the side of the panel 100 facing away from the indoor environment. In other words, the sterilization module, installed inside the air conditioner indoor unit 1, fully sterilizes the heat exchanger and air duct, ensuring the effectiveness of the sterilization module and improving its efficiency.

[0046] Furthermore, at least one transparent area 110 is provided on the panel 100 for displaying the operating status of the sterilization module located inside the panel 100, so that the user can directly see whether the sterilization module is operating. By providing the transparent area 110 on the panel 100 to display the operating status of the sterilization module to the user, the air conditioner indoor unit 1 of the present invention can intuitively determine whether the sterilization function of the air conditioner indoor unit 1 is turned on based on the display status of the transparent area 110, eliminating the user's doubts about whether the sterilization function is active and achieving visualization of the sterilization function.

[0047] In some embodiments, as Figure 1 As shown, the air conditioner indoor unit 1 is a wall-mounted unit, with the panel 100 extending horizontally. An air outlet 21 is provided at the front bottom of the housing 20, extending in the same direction as the panel 100. A transparent area 110 is located above the air outlet 21, ensuring that the sterilization function is visualized and the air outlet function of the air conditioner indoor unit 1 is not affected by each other.

[0048] In a specific embodiment, the transparent region 110 can be located in the middle of the panel 100 in the width direction, so that the transparent region 110 is spaced apart from both the upper and lower edges of the panel 100, thereby ensuring that the transparent region 110 is conspicuous on the entire panel 100. In addition, the transparent region 110 can be located in a side region in the length direction of the panel 100, so that the panel 100 has an asymmetrical aesthetic, thereby ensuring the overall aesthetics of the air conditioner indoor unit 1.

[0049] The air conditioner indoor unit 1 of the embodiment of the present invention is provided with a transparent area 110 on the panel 100. When the sterilization function of the air conditioner indoor unit 1 is turned on, the transparent area 110 can intuitively show the user whether the sterilization function is turned on, eliminating the user's doubts about whether the sterilization function is in the air conditioner, realizing the visualization of the sterilization function, and improving the user's experience. The structure of the panel assembly 10 of the present invention is described in detail below.

[0050] Figure 2 is a schematic structural diagram of a panel assembly according to an embodiment of the present invention. Figure 3 FIG is a schematic exploded view of a panel assembly according to one embodiment of the present invention. Figure 2 and Figure 3 As shown, the panel assembly 10 of the present invention may include a panel 100 and a sterilization module 200 .

[0051] like Figure 2 As shown, the panel 100 is provided with at least one transparent area 110, and the sterilization module 200 is disposed on the panel 100. After the sterilization module 200 is activated, the transparent area 110 on the panel 100 transmits the light emitted by the sterilization module 200 during operation. In other words, the panel assembly 10 of the embodiment of the present invention improves the structure and material of a local area of ​​the panel 100, adding the transparent area 110 to display the operating status of the sterilization module 200 located on the inner side of the panel 100. This allows the user to directly see whether the sterilization module 200 is present and operating, thus achieving visualization of the sterilization function.

[0052] like Figure 3 As shown, a light-emitting device 210 is provided on the side of the sterilization module 200 facing the panel 100. The light-emitting device 210 is used to emit light toward the transparent area 110 after the sterilization module 200 is activated, thereby more intuitively displaying the operating status of the sterilization module 200. In other words, the panel assembly 10 of the embodiment of the present invention further improves the structure of the sterilization module 200 by adding the light-emitting device 210 on the side facing the transparent area 110. The light-emitting device 210 increases the brightness of the light transmitted from the transparent area 110 to the indoor environment, improves the sensitivity of the display of the transparent area 110, and ensures the stability of the visualization of the sterilization function.

[0053] The panel assembly 10 of an embodiment of the present invention includes a panel 100 and a sterilization module 200. The panel 100 is provided with at least one transparent area 110 to show the user at least part of the components inside the panel 100. The sterilization module 200 is provided on the panel 100, and a light-emitting device 210 is provided on the side facing the panel 100, which is used to emit light into the transparent area 110 after the sterilization module 200 is activated to display the working status of the sterilization module 200. In other words, the present invention provides a transparent area 110 on the panel 100. After the sterilization module 200 is activated, the transparent area 110 can transmit the light emitted by the sterilization module 200 to display the working status of the sterilization module 200 to the user. By improving the structure and material of the local area of ​​the panel 100 and improving the structure of the sterilization module 200, the panel assembly 10 of the present invention avoids the problem that the ultraviolet sterilization function is invisible and the user has difficulty in judging whether the sterilization function is operating normally during use. Instead, the working status of the sterilization module 200 is intuitively displayed to the user, achieving visualization of the sterilization function and improving the user experience.

[0054] In some embodiments, as Figure 3 As shown, the light emitting device 210 includes at least one ultraviolet light irradiation unit, which is disposed adjacent to the transparent region 110 and configured to emit ultraviolet light toward the transparent region 110. In other words, the light emitting device 210 of this embodiment of the present invention is disposed on the inner side of the panel 100 adjacent to the transparent region 110. As a result, the ultraviolet light emitted by the light emitting device 210 can directly irradiate the transparent region 110, thereby improving the clarity of the display in the transparent region 110.

[0055] Furthermore, transparent region 110 is configured to display a preset color when exposed to ultraviolet light from the ultraviolet irradiation unit. In other words, transparent region 110 exhibits a photochromic function in response to ultraviolet light. Consequently, when ultraviolet light from light-emitting device 210 directly irradiates transparent region 110, it directly changes color to the preset color, further enhancing the clarity of the display in transparent region 110.

[0056] The light-emitting device 210 of the embodiment of the present invention includes at least one ultraviolet irradiation unit, which is arranged adjacent to the transparent area 110 and is used to emit ultraviolet light to the transparent area 110. The transparent area 110 is configured to display a preset color under the irradiation of the ultraviolet light emitted by the ultraviolet irradiation unit, thereby realizing the photochromic function of the transparent area 110 on the panel 100. By adding a photochromic function to the transparent area 110, the panel assembly 10 of the present invention realizes that after the sterilization module 200 is activated, a local area of ​​the panel 100 directly displays a preset color, thereby preventing the problem of unclear light from the transparent area 110 after the sterilization module 200 is activated due to external factors such as the user's unfavorable viewing angle and the indoor environment being too bright. This improves the adequacy of displaying the working status of the sterilization module 200, thereby improving the accuracy of the visualization of the sterilization function, and further enhancing the user experience.

[0057] In an optional embodiment, the preset color can be set to purple, showing the user the normal operation of the ultraviolet sterilization function in the same color as ultraviolet light, thereby improving the visual intuitiveness of the sterilization function and thus improving the user experience.

[0058] In another optional embodiment, the preset color can be set to red, showing the user the normal operation of the ultraviolet sterilization function in a color different from ultraviolet light, avoiding the user's mistaken belief that ultraviolet light is leaking when the sterilization module 200 is running, and eliminating the user's panic that the operation of the sterilization module 200 will cause harm to the human body, thereby improving the user's experience.

[0059] Figure 4 FIG is a schematic cross-sectional view of a panel assembly according to an embodiment of the present invention. Figure 4 As shown, the transparent area 110 includes a through hole 111 opened on the panel 100, a transparent material 112 installed in the through hole 111, and a photochromic coating (not shown in the figure) coated on the surface of the transparent material 112.

[0060] The photochromic coating displays a preset color under ultraviolet light and returns to its original color when the ultraviolet light ceases. Thus, the panel assembly 10 of the present invention is provided with a photochromic coating in the transparent region 110 of the panel 100, achieving accurate photochromic display within the transparent region 110. Furthermore, the panel assembly 10 of the present invention has the photochromic coating evenly distributed only in the transparent region 110 of the panel 100, avoiding the problem of uneven color display caused by uneven distribution of ultraviolet light when the photochromic material is too widely distributed. This achieves uniform color display within the transparent region 110, improving the overall aesthetics.

[0061] In some embodiments, the UV light emitted by the UV irradiation unit has a wavelength range of 100 to 280 nanometers. UV light within this wavelength range has a good sterilization effect but relatively low penetration, reducing the risk of UV light passing through the transparent region 110 and into the room, potentially posing a health hazard. Furthermore, the transparent material 112 has UV resistance. In other words, the panel assembly 10 of the present invention utilizes a material with excellent UV resistance as the transparent material 112 disposed in the transparent region 110.

[0062] In one embodiment, the substrate of panel 100 can be ABS, PS, or PP. Transparent region 110 can be made of transparent PMMA, which has excellent UV resistance and effectively blocks UV rays. The photochromic coating is made of photochromic ink, which changes from its natural color to purple, red, orange, green, or other colors under UV light.

[0063] The ultraviolet light emitted by the ultraviolet irradiation unit of the present invention has a wavelength range of 100 to 280 nanometers. Ultraviolet light within this wavelength range has a good sterilization effect but poor penetration, reducing the harm to the human body caused by ultraviolet light passing through transparent area 110. In addition, the transparent material 112 used in transparent area 110 of the present invention has ultraviolet resistance, which reduces the penetration of ultraviolet light through transparent area 110, further reducing the harm of ultraviolet light to the human body. While ensuring the visual sterilization function, it does not harm the human body, thereby improving the safety of the visual sterilization function and enhancing the user experience.

[0064] Figure 5 FIG is a schematic structural diagram of a sterilization module according to an embodiment of the present invention. Figure 4 and Figure 5 As shown, the sterilization module 200 is provided with at least one ultraviolet sterilization unit 230 on a side facing away from the panel 100. This unit is configured to emit ultraviolet light in a direction away from the panel 100 after the sterilization module 200 is activated, thereby sterilizing the interior of the device where the panel assembly 10 is located. In other words, the sterilization module 200 is further provided with one or more ultraviolet sterilization units 230 on a side opposite the light-emitting device 210. Thus, when the panel assembly 10 is mounted on the housing 20 of the air conditioner indoor unit 1, and the one or more ultraviolet sterilization units 230 of the sterilization module 200 are positioned toward the heat exchanger and the air duct, the light-emitting device 210 is positioned away from the heat exchanger and the air duct, i.e., toward the panel 100.

[0065] In some embodiments, as Figures 3 to 5As shown, the sterilization module 200 also includes a lamp holder 220. The lamp holder 220 is mounted on the panel 100 and is used to assemble the sterilization module 200 with the panel 100. The light emitting device 210 includes ultraviolet lamp beads arranged on the side of the lamp holder 220 facing the panel 100. In addition, all ultraviolet sterilization units 230 of the sterilization module 200 can be ultraviolet lamp beads.

[0066] The sterilization module 200 of the present invention includes a lamp holder 220 and multiple UV lamps positioned on either side of the lamp holder 220. This secures the sterilization module 200 and the panel 100 while ensuring stable visualization of the sterilization function. Furthermore, the sterilization module 200 has a simple structure, effectively reducing the production cost of the entire panel assembly 10.

[0067] In some embodiments, after the sterilization module 200 is started, the ultraviolet lamp beads on the front of the lamp holder 220 irradiate the heat exchanger and the air duct for sterilization, while the ultraviolet lamp beads on the back of the lamp holder 220 irradiate the transparent area 110, causing the photosensitive color-changing coating on its surface to change color. The transparent area 110 will change from transparent to a preset color under the irradiation of ultraviolet rays.

[0068] The panel assembly 10 of the present invention adds a transparent area 110 with a photochromic effect on the surface of the panel 100, making the operation process of the sterilization module 200 intuitively visible, helping users to observe the operating status of the sterilization function, and increasing the aesthetics of the panel 100.

[0069] In some embodiments, as Figure 2 and Figure 5 As shown, a plurality of ultraviolet sterilization units 230 are provided on the side of the sterilization module 200 away from the panel 100, and the plurality of ultraviolet sterilization units 230 are evenly spaced in the longitudinal direction of the lamp frame 220. Specifically, as Figure 2 and Figure 3 As shown, the length direction of the lamp holder 220 is the same as the length direction of the panel 100. Therefore, the multiple ultraviolet sterilization units 230 arranged on the side of the sterilization module 200 away from the panel 100 can uniformly irradiate the interior of the device where the panel 100 is located, thereby improving the uniformity of the distribution of the sterilization medium and ensuring the sterilization efficiency.

[0070] In some embodiments, as Figure 1 As shown, the through hole 111 and the transparent material 112 can each be annular with the same diameter. Specifically, the transparent material 112 is a circular ring made of transparent PMMA material, and the through hole 111 is an annular hole opened in a designated area on the surface of the panel 100. The circular ring and the annular hole have the same diameter. In one embodiment, the circular ring and the annular hole are bonded together using hot melt adhesive or a snap fit.

[0071] Thus, a circular transparent area 110 is formed on the surface of the panel 100 of the present invention, which improves the appearance of the panel assembly 10. When the panel assembly 10 is installed on the casing 20 of the air conditioner indoor unit 1, the overall aesthetics of the air conditioner is improved.

[0072] In some embodiments, as Figure 3 As shown, the through hole 111 and the transparent material 112 may also be semi-annular in shape with the same diameter.

[0073] Specifically, the transparent material 112 can be a semicircular ring made of transparent PMMA material, and the through hole 111 is a semicircular hole opened in a designated area on the surface of the panel 100. The semicircular ring and the semicircular hole have the same diameter, and the through hole 111 and the transparent material 112 are installed and fixed by hot melt adhesive or snap fastening.

[0074] In one embodiment, the panel 100 is provided with two semi-circular transparent areas 110, with the openings of the two semi-circular transparent areas 110 facing each other. Thus, the panel 100 of the present invention forms two semi-circular transparent areas 110, which not only maintains the appearance of the panel assembly 10 but also divides the area capable of photochromic change into two halves, facilitating a more diverse visual effect and a richer functional display.

[0075] Furthermore, the two semi-annular transparent regions 110 provided on the panel 100 can be spaced apart across the width of the panel 100, thereby achieving spatial separation. Furthermore, the spaced-apart arrangement of the two transparent regions 110 allows the panel 100 to be disposed continuously between the two transparent regions 110, thereby reducing the structural complexity of the panel 100 and the production cost of the panel assembly 10.

[0076] In some embodiments, as Figure 1 or Figure 3 As shown, the ratio of the area of ​​the transparent region 110 to the area of ​​the panel 100 can be 0.01 to 0.1. Specifically, the area of ​​the panel 100 refers to the area of ​​the surface of the side of the panel 100 provided with the transparent region 110. Furthermore, the ratio of the area of ​​each transparent region 110 to the area of ​​the surface of the side of the panel 100 provided with the transparent region 110 can be 0.01 to 0.05, which avoids the problem of poor overall aesthetics of the panel 100 due to the transparent region 110 occupying too large a proportion on the panel 100, and also limits the area of ​​the transparent region 110, thereby improving the uniformity of color display. At the same time, the ratio of the area of ​​each transparent region 110 to the area of ​​the surface of the side of the panel 100 provided with the transparent region 110 is not less than 0.01, which ensures clear display of colors, thereby improving the user experience.

[0077] In a specific embodiment, the ratio of the sum of the areas of all transparent areas 110 to the area of ​​the surface of the panel 100 on which the transparent areas 110 are provided can be 0.02, thereby ensuring clear display of colors while limiting the area of ​​the transparent areas 110 to improve the uniformity of color display.

[0078] In some embodiments, a plurality of transparent areas 110 may be provided on the panel 100, dividing the area that can be photochromic into multiple parts, so as to achieve more diverse visual effects and richer functional displays. Accordingly, the light-emitting device 210 may also include multiple ultraviolet light irradiation units, and the multiple ultraviolet light irradiation units and the multiple transparent areas 110 are provided in a one-to-one correspondence. On this basis, each transparent area 110 is configured to display a preset color under the irradiation of ultraviolet light emitted by the corresponding ultraviolet light irradiation unit. In other words, the multiple transparent areas 110 can be photochromic separately to achieve more diverse visual effects and richer functional displays.

[0079] Furthermore, the plurality of UV irradiation units can be configured to activate a preset number of UV irradiation units according to the sterilization intensity of the sterilization module 200, so that the number of transparent areas 110 displaying a preset color varies under different sterilization intensities. Specifically, the preset number of UV irradiation units is set according to the sterilization intensity of the sterilization module 200, and increases sequentially as the sterilization intensity increases.

[0080] For example, Figure 3 As shown, the plurality of transparent regions 110 may include a first color-changing region 1101 and a second color-changing region 1102. The plurality of ultraviolet light irradiation units may include a first ultraviolet lamp bead and a second ultraviolet lamp bead. The first ultraviolet lamp bead and the first color-changing region 1101 are arranged opposite each other to irradiate ultraviolet light toward the first color-changing region 1101. The second ultraviolet lamp bead and the second color-changing region 1102 are arranged opposite each other to irradiate ultraviolet light toward the second color-changing region 1102.

[0081] When the number of bacteria in the use environment is large and the sterilization intensity of the sterilization module 200 is at high intensity, the first ultraviolet lamp bead and the second ultraviolet lamp bead are both started, and the first color-changing area 1101 and the second color-changing area 1102 are simultaneously sensitive to light and change color, displaying the preset color to show that it is currently in a high-intensity sterilization mode.

[0082] As sterilization module 200 continues to operate, the number of bacteria in the environment decreases. When the number of bacteria in the environment falls below a preset threshold, sterilization module 200 reduces its sterilization intensity to low intensity. At this point, one of the first and second UV lamps is turned off, and one of the first and second color-changing regions 1101, 1102 ceases to change color due to light exposure and returns to its original color. Only transparent region 110 remains, displaying the preset color, to indicate that the device is currently in low-intensity sterilization mode.

[0083] The panel assembly 10 of the embodiment of the present invention realizes the differentiated display of sterilization functions with different sterilization intensities by setting multiple transparent areas 110 and multiple ultraviolet light irradiation units respectively set corresponding to the multiple transparent areas 110, realizes richer function display, and further improves the user experience.

[0084] In some embodiments, the panel 100 may be provided with only one transparent area 110, and the transparent area 110 may be configured to display different preset colors under the illumination of ultraviolet light of different intensities. In other words, as the intensity of the ultraviolet light changes, the color displayed by the transparent area 110 on the panel 100 may also change accordingly.

[0085] In an alternative embodiment of this embodiment, the light-emitting device 210 may include multiple UV irradiation units, each of which is positioned adjacent to the transparent region 110. As the number of UV irradiation units activated changes, the intensity of the UV light received by the transparent region 110 changes, and thus the color displayed by the transparent region 110 changes accordingly. In other words, the transparent region 110 on the panel 100 can be irradiated with UV light of varying intensities and change to different colors, thereby achieving a wider range of visual effects and a richer range of functional displays.

[0086] Furthermore, the plurality of ultraviolet irradiation units can be configured to activate a preset number of ultraviolet irradiation units according to the sterilization intensity of the sterilization module 200, so that the intensity of the ultraviolet light irradiated on the transparent area 110 varies. Specifically, the preset number of ultraviolet irradiation units is set according to the sterilization intensity of the sterilization module 200, and increases sequentially as the sterilization intensity increases.

[0087] For example, Figure 1 As shown, the panel 100 may also be provided with only one transparent area 110. The multiple ultraviolet light irradiation units may include a first ultraviolet lamp bead, a second ultraviolet lamp bead, and a third ultraviolet lamp bead. The first ultraviolet lamp bead, the second ultraviolet lamp bead, and the third ultraviolet lamp bead are all arranged near the center of the transparent area 110 and are all used to irradiate ultraviolet light toward the transparent area 110.

[0088] When the number of bacteria in the use environment is large and the sterilization intensity of the sterilization module 200 is at high intensity, the first ultraviolet lamp bead, the second ultraviolet lamp bead and the third ultraviolet lamp bead are all started, and the intensity of the ultraviolet light irradiated on the transparent area 110 is in the high intensity range. The transparent area 110 turns red to show that it is currently in a high-intensity sterilization mode.

[0089] As the sterilization module 200 continues to operate, the number of bacteria in the environment decreases. When the number of bacteria in the environment falls below a first preset threshold, the sterilization intensity of the sterilization module 200 is reduced to low intensity. At this time, one of the first, second, or third UV lamp beads is turned off, and the intensity of the UV light irradiating the transparent area 110 is reduced from the high intensity range to the medium intensity range. The light sensitivity of the transparent area 110 switches from purple to orange to indicate that it is currently in low-intensity sterilization mode.

[0090] As the sterilization module 200 continues to operate, the number of bacteria in the use environment drops to a minimum. When the number of bacteria in the use environment is lower than the second preset threshold, the sterilization intensity of the sterilization module 200 drops to zero intensity. The second preset threshold is lower than the first preset threshold. At this time, the multiple ultraviolet sterilization units 230 set on the side of the sterilization module 200 away from the panel 100 are turned off, and two of the first ultraviolet lamp beads, the second ultraviolet lamp beads, and the third ultraviolet lamp beads are turned off. The intensity of the ultraviolet light irradiated on the transparent area 110 drops from the medium intensity range to the low intensity range, and the photosensitivity of the transparent area 110 switches from orange to green to show that it is currently in the zero-intensity sterilization mode, indicating that the sterilization has been completed.

[0091] The panel assembly 10 of an embodiment of the present invention configures the transparent area 110 to display different preset colors under the irradiation of ultraviolet light of different intensities, and sets a plurality of ultraviolet light irradiation units in the transparent area 110 that can be turned on or off as the sterilization intensity changes, thereby achieving differentiated display of sterilization functions with different sterilization intensities, achieving richer functional display, and further improving the user experience.

[0092] In another optional implementation of this embodiment, the light-emitting device 210 may include an ultraviolet light irradiation unit, and the light-emitting device 210 may be configured to adjust the intensity of the emitted ultraviolet light according to the sterilization intensity of the sterilization module 200, so that the transparent area 110 displays different colors under different sterilization intensities.

[0093] For example, Figure 1 As shown, the panel 100 may also be provided with only one transparent area 110 , and the light emitting device 210 includes an ultraviolet light irradiation unit disposed adjacent to the center of the transparent area 110 .

[0094] When the number of bacteria in the use environment is large and the sterilization intensity of the sterilization module 200 is high, the ultraviolet irradiation unit emits ultraviolet light of the first intensity, and the transparent area 110 turns red to indicate that it is currently in the high-intensity sterilization mode.

[0095] As sterilization module 200 continues to operate, the number of bacteria in the environment decreases. When the number of bacteria in the environment falls below a first preset threshold, sterilization module 200 reduces its sterilization intensity to low intensity. At this point, the UV irradiation unit emits UV light at a second intensity, and the transparent area 110 switches from purple to orange, indicating that the system is currently in low-intensity sterilization mode.

[0096] As the sterilization module 200 continues to operate, the number of bacteria in the use environment drops to a minimum. When the number of bacteria in the use environment is lower than the second preset threshold, the sterilization intensity of the sterilization module 200 drops to zero intensity. The second preset threshold is lower than the first preset threshold. At this time, the multiple ultraviolet sterilization units 230 arranged on the side of the sterilization module 200 facing away from the panel 100 are turned off, and the ultraviolet light irradiation unit emits ultraviolet light of the third intensity, and the first intensity, the second intensity and the third intensity decrease in sequence. Under the irradiation of the third intensity of ultraviolet light, the transparent area 110 switches from orange to green to show that it is currently in the zero-intensity sterilization mode, indicating that the sterilization has been completed.

[0097] The panel assembly 10 of the embodiment of the present invention configures the transparent area 110 to display different preset colors under the irradiation of ultraviolet light of different intensities, and provides an ultraviolet light irradiation unit in the transparent area 110 that can change the intensity of the emitted ultraviolet light as the sterilization intensity changes. This achieves a differentiated display of sterilization functions with different sterilization intensities, improves the user's intuitive feeling of different sterilization intensities, achieves richer function display, and further improves the user experience.
