Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a range hood based on a transparent control panel and its control method. Background Technology

[0002] In the current field of range hood technology, touch display control panels have gained a certain market share due to their simple appearance and convenient operation.

[0003] Touchscreen control panels are mainly divided into non-transparent control panels and transparent control panels. Compared with non-transparent control panels, transparent control panels can blend better with the surrounding environment and are almost "invisible" when not in use, making the overall appearance of the range hood more concise.

[0004] However, due to the transparent material of the control panel, the icons are easily affected by the color and brightness of the ambient background, making it difficult for users to see the operation icons, thus interfering with normal use and greatly reducing the user experience. Summary of the Invention

[0085] Figure 1 This is a structural schematic diagram of a range hood provided in an embodiment of the present invention. Figure 2 This is a bottom view structural diagram of a range hood provided in an embodiment of the present invention. Figure 3 This is provided by the embodiments of the present invention. Figure 2 Enlarged view of point A in the image. Figure 4 This is a cross-sectional view of the range hood provided in an embodiment of the present invention at the light-transmitting glass.

[0086] First, refer to Figures 1-4 The range hood includes a panel assembly 20 and a controller (not shown in the figure); the panel assembly 20 includes a transparent glass 21, a light-emitting element 22 and a light sensor 23; the transparent glass 21 is provided with control icons 24, and the light-emitting element 22 is positioned facing the control icons 24 on the transparent glass 21.

[0087] The light-emitting element 22 is used to scatter the emitted light through the control icon 24 when it is lit to display the control icon 24; the light sensor 23 is used to detect the ambient color and ambient light brightness of the range hood; the controller is electrically connected to the light sensor 23 and the light-emitting element 22 respectively, and is used to control the light emission color and light emission brightness of the light-emitting element 22 according to the ambient color and ambient light brightness of the range hood.

[0088] Based on the above-described range hood, this embodiment of the invention also provides a range hood control method. Figure 5 This is a flowchart of a range hood control method provided in an embodiment of the present invention, such as... Figure 5 As shown, the method includes:

[0089] S110, controls the light sensor to detect the ambient color and ambient light brightness of the range hood.

[0090] Among them, ambient color can be understood as the color and brightness of the wall where the range hood is installed; ambient light brightness can be understood as the brightness of the light in the environment where the range hood is located.

[0091] Specifically, such as Figure 3 The control icon shown is positioned so that the light sensor faces the transparent glass. The light sensor can detect the color of the wall where it is installed and the light intensity around the range hood through the transparent glass.

[0092] S120. Control the light emission color and brightness of the light-emitting element according to the ambient color and ambient light brightness of the range hood.

[0093] Specifically, range hoods can adjust the color and brightness of their light-emitting elements based on factors that affect the display effect of the light-emitting elements, such as the color of the environment where the range hood is located and the ambient light level.

[0094] For example, in night cooking mode, the control system reduces the brightness of the light-emitting element according to the ambient light level; when the wall color is light (such as white), a darker color, such as dark blue, is selected; when the wall color is dark (such as black), a light color, such as white or light yellow, can be selected for the light-emitting element.

[0095] This invention discloses a control method based on a transparent control panel. The range hood includes a panel assembly; the panel assembly includes transparent glass, a light-emitting element, and a light sensor; control icons are provided on the transparent glass, and the light-emitting element is positioned facing the control icons on the transparent glass; the control method includes: controlling the light sensor to detect the ambient color and ambient light intensity of the range hood to obtain the real-time external environment when the range hood is working; and controlling the light emission color and brightness of the light-emitting element according to the ambient color and ambient light intensity of the range hood, thereby solving the problem that the transparent control panel is difficult to adapt to different external light intensities or working environment backgrounds, resulting in unclear display of the display panel, and realizing clear display of the control panel under any ambient color and ambient light intensity conditions.

[0096] like Figure 3 As shown, in some embodiments, the panel assembly 20 further includes a smoke sensor 26 and / or a steam sensor 27; the controller is electrically connected to the smoke sensor 26 and / or the steam sensor 27, and is used to control the smoke sensor 26 to detect the smoke concentration in the environment where the range hood is located, and / or to control the steam sensor 27 to detect the steam concentration in the environment where the range hood is located; and when the smoke concentration in the environment where the range hood is located exceeds a preset smoke concentration threshold, and / or when the steam concentration in the environment where the range hood is located exceeds a preset steam concentration threshold, performs at least one of the following three operations:

[0097] Adjust the range hood setting upwards;

[0098] Change the light emission color of the light-emitting element 22 to a preset color with strong penetrating power;

[0099] The light emission mode of the light-emitting element 22 is changed to flashing light.

[0100] Similarly, the above control methods also include:

[0101] Control the smoke sensor to detect the smoke concentration in the environment where the range hood is located, and / or control the steam sensor to detect the steam concentration in the environment where the range hood is located;

[0102] When the smoke concentration in the environment where the range hood is located exceeds a preset smoke concentration threshold, and / or when the steam concentration in the environment where the range hood is located exceeds a preset steam concentration threshold, perform at least one of the following three operations:

[0103] Adjust the range hood setting upwards;

[0104] Change the light-emitting element's emission color to a preset color with strong penetrating power;

[0105] Change the light emission mode of the light-emitting element to flashing light.

[0106] Among them, the preset smoke concentration threshold can be understood as a standard used to measure whether the smoke concentration in the environment where the range hood is located has reached the level that requires further measures; the steam concentration threshold can be understood as a limit used to judge whether the steam concentration in the environment is too high.

[0107] Specifically, such as Figure 3 As shown, at least one of a smoke sensor 26 and a steam sensor 27 is provided in the range hood panel assembly. Correspondingly, when the concentration of smoke and steam in the kitchen is too high, the control system will selectively execute at least one of the three response methods: increasing the gear level, changing the light color, and changing the light mode, so as to ensure that the range hood can deal with the situation of excessive smoke and steam concentration in the kitchen more intelligently and effectively, and ensure that users can clearly see the control icons.

[0108] like Figure 3 As shown, in some embodiments, the panel assembly 20 further includes an infrared detection module 28; the controller is electrically connected to the infrared detection module 28 and is used to control the infrared detection module 28 to detect the user's touch operation and touch position; and when the user's touch operation is detected, the user's touch position is determined; when the user's touch position deviates from a preset position range, at least one of the following two operations is performed:

[0109] Change the light emission color of the light-emitting element 22 to a preset color with strong penetrating power;

[0110] The light emission mode of the light-emitting element 22 is changed to flashing light.

[0111] Similarly, the above control methods also include:

[0112] Control the infrared detection module to detect the user's touch operation and touch position;

[0113] When a user touch operation is detected, the user's touch location is determined;

[0114] When the user's touch position deviates from the preset position range, perform at least one of the following two operations:

[0115] Change the light-emitting element's emission color to a preset color with strong penetrating power;

[0116] Change the light emission mode of the light-emitting element to flashing light.

[0117] Touch operation can be understood as the interactive action of a user touching or approaching the touch area on the range hood panel component with their finger; touch position can be understood as the specific location where the finger touches the touch area of ​​the panel component; preset position range can be understood as a pre-set ideal touch area corresponding to each operation function. Only when the user's touch position is within this range can the control system accurately recognize and execute the corresponding operation command. For example, different control icons (such as power buttons, speed adjustment buttons, etc.) have their own corresponding preset position ranges on the panel.

[0118] Specifically, such as Figure 3 As shown, the infrared module 28 can detect the touch area on the panel assembly. When the user's touch position deviates from the preset range, the system cannot accurately determine the user's intention and cannot execute the corresponding operation. Therefore, it is necessary to remind the user that they have not touched the preset range by changing the light emission color or changing the light emission mode. Specifically, for example... Figure 3 As shown, the infrared module 28 can also detect the touch area on the panel assembly. When the user's touch position deviates from the preset range, the system cannot accurately determine the user's intention and cannot execute the corresponding operation. Therefore, it is necessary to remind the user that they have not touched the preset range by changing the light color or the light emission mode, promptly informing the user of the operation error, guiding the user to operate correctly, improving the user's interaction experience with the range hood, reducing the trouble caused by improper operation, and making the use of the range hood more convenient and efficient.

[0119] Figure 6 This is a flowchart of another range hood control method provided by an embodiment of the present invention. This embodiment refines the above embodiment's step "S110, controlling the light sensor to detect the ambient color and ambient light brightness of the range hood," and specifically includes:

[0120] Detect the ambient color around the range hood when it is first turned on or within the range hood's preset usage period;

[0121] Based on the ambient color and light intensity of the range hood, the color and brightness of the light-emitting elements are controlled, including:

[0122] Based on the ambient color of the range hood, the light-emitting element is controlled to light up with the target light-emitting color; wherein, the target light-emitting color and the ambient color of the range hood have a first preset mapping relationship.

[0123] like Figure 6 As shown, the method includes:

[0124] S210. Detect the ambient color of the range hood when it is first turned on or within the preset usage period of the range hood.

[0125] The first power-on can be understood as the moment when the range hood is first connected to the power supply and starts running; the preset usage cycle of the range hood can be understood as the preset time interval at which the range hood periodically checks the ambient color while keeping the power supply on.

[0126] Specifically, when the user first connects the range hood to the power supply and presses the start button, or when it has been running continuously for a preset period, the system will activate the ambient color detection function to obtain ambient color information, providing a basis for the subsequent light-emitting elements to determine the display color.

[0127] For example, the preset usage period can be one month. When the preset usage period is reached, the range hood will check the ambient color to avoid changes in ambient color caused by use or other reasons (such as white walls turning yellow due to cooking fumes) affecting display clarity.

[0128] S220: Control the light-emitting element to light up in the target light color according to the ambient color of the range hood.

[0129] The target emission color has a first preset mapping relationship with the ambient color of the range hood. This first preset mapping relationship can be understood as a pre-set emission rule, the purpose of which is to ensure that the color presented by the emission element makes the control icons and other displayed content clearly visible regardless of the color of the environment in which the range hood is located. For example, according to the first preset mapping relationship, when the ambient color is light (such as white), the emission element selects a darker color, such as dark blue; when the ambient color is dark (such as black), it selects a light color, such as white or light yellow.

[0130] Specifically, the range hood's control system detects the ambient color of the range hood using a light sensor, matches it according to a first preset mapping relationship, determines the target luminous color, and then sends a command to the luminous element to generate a light signal of the target color.

[0131] This invention, through detecting ambient color upon initial power-on and at preset intervals, controls the color of the luminous element according to a preset mapping relationship, ensuring clear display of control icons, enhancing the visual harmony between the range hood and the environment, and improving user convenience and overall experience.

[0132] In an optional embodiment, the center wavelength of the ambient color of the range hood is λ1, and the center wavelength of the target emission color is λ2; wherein, the first preset mapping relationship satisfies: when λ1≤565nm, λ2=λ1+185nm; when λ1>565nm, λ2=λ1-185nm.

[0133] First, it should be noted that since the ambient color of the range hood and the emission color of the light-emitting element are generally within a certain wavelength range of the spectrum, for accurate control, this embodiment uses the wavelength with the highest energy in the spectrum as the center wavelength to represent the ambient color and the emission color of the light-emitting element. The process of determining the target emission color of the light-emitting element based on the ambient color is determined by a first preset mapping relationship, the purpose of which is to increase the contrast between the emission color of the light-emitting element and the ambient color.

[0134] Those skilled in the art will know that the visible light band is 380nm-750nm, and the colors from 750nm to 380nm are red, orange, yellow, green, cyan, blue, and violet, respectively. Based on this, in this embodiment, when the ambient light center wavelength λ1 ≤ 565nm, for example, when the ambient color is violet (λ1 = 380nm), the target emission color center wavelength λ2 = λ1 + 185nm = 565nm. At this time, the target emission color is yellow-green, and the light-emitting element emits yellow-green light, forming a complementary color with the violet ambient color, creating a clear difference. This ensures the control icon is clearly displayed, facilitating user comprehension of its content. When λ1 > 565nm, for example, when the ambient color is yellow-green (λ1 = 565nm), the target emission color center wavelength λ2 = λ1 - 185nm = 380nm. At this time, the target emission color is violet, and the light-emitting element emits violet light, forming a complementary color with the yellow-green ambient color, creating a clear difference. This also ensures the control icon is clearly displayed, facilitating user comprehension of its content.

[0135] Figure 7 This is a flowchart of another range hood control method provided by an embodiment of the present invention. This embodiment refines the above embodiment's step "S110, controlling the light sensor to detect the ambient color and ambient light brightness of the range hood," and specifically includes:

[0136] During the operation of the range hood, the real-time ambient light level of the range hood is detected;

[0137] Based on the ambient color and light intensity of the range hood, the color and brightness of the light-emitting elements are controlled, including:

[0138] Based on the real-time ambient light level of the range hood, the light-emitting element is controlled to light up at a target brightness level; wherein, the target brightness level and the real-time ambient light level of the range hood have a second preset mapping relationship.

[0139] like Figure 7 As shown, the method includes:

[0140] S310. During the operation of the range hood, detect the real-time ambient light level of the range hood.

[0141] Among them, real-time ambient light brightness can be understood as the brightness of the constantly changing light in the environment in which the range hood is located when it is in operation.

[0142] Specifically, once the range hood starts working, the light sensor will periodically detect the ambient light brightness at a suitable time interval based on the actual situation, such as once per second, to provide data support for subsequent brightness adjustments.

[0143] S320: Based on the real-time ambient light level of the range hood, control the light-emitting element to illuminate at the target brightness.

[0144] Among them, the target luminous brightness and the real-time ambient light brightness of the range hood have a second preset mapping relationship. The target luminous brightness can be understood as the brightness value that the luminous element should have after calculation or mapping based on the real-time ambient light brightness. The second preset mapping relationship can be understood as a pre-set rule or function between the real-time ambient light brightness and the target luminous brightness.

[0145] Specifically, after the control system receives real-time ambient light brightness information, it will calculate based on the second preset mapping relationship to determine the corresponding target luminous brightness.

[0146] For example, assuming the second preset mapping relationship is linear, for instance, when the real-time ambient light intensity is 500 lux, the target luminous intensity may be determined to be 80% of the maximum luminous intensity; when the real-time ambient light intensity is 100 lux, the target luminous intensity may be adjusted to 30% of the maximum luminous intensity.

[0147] This invention detects the ambient light intensity when the range hood is working in real time and determines the target luminous intensity based on a preset mapping relationship to illuminate the light-emitting element. This allows the light-emitting element to adjust its brightness according to changes in ambient light, ensuring a clear and visible operating interface and improving the user experience.

[0148] In an optional embodiment, controlling the emission color and brightness of the light-emitting element 22 according to the ambient color and ambient light intensity of the range hood further includes:

[0149] Based on the ambient color of the range hood, the target emission color range of the light-emitting element is determined; the center wavelength of the target emission color range has a first preset mapping relationship with the center wavelength of the ambient color of the range hood.

[0150] Obtain the emission color of the light-emitting element selected by the user;

[0151] Control the light-emitting element 22 to light up in the light-emitting color selected by the user;

[0152] The real-time ambient light intensity of the range hood is L1, and the target luminous intensity of the light-emitting element 22 is L2; ​​where:

[0153] When the emission color of the user-selected light-emitting element 22 is within the target emission color range, the second preset mapping relationship satisfies: L2=L1+k1*L1;

[0154] When the emitted color of the user-selected light-emitting element 22 is outside the target emitted color range, the second preset mapping relationship satisfies: L2=L1+k2*L1 2 ;

[0155] Where k1 and k2 are both constants greater than 0.

[0156] Specifically, the range hood in this embodiment of the invention can be equipped with an interactive module or interactive function, allowing users to freely choose their preferred icon illumination color. Simultaneously, the range hood itself also has an ambient color detection function, and based on a first preset mapping relationship, it can determine the target illumination color range of the light-emitting element that differs significantly from the ambient color. In other words, based on the known ambient color, the target illumination color range that differs significantly from the ambient color can be calculated using the first preset mapping relationship. Since the function of allowing users to freely choose the icon illumination color is added, there are two possibilities: the user-selected color falls within the target illumination color range, and the color does not fall within the target illumination color range. To address these two possibilities, this embodiment of the invention provides two implementation methods for the target illumination brightness of the light-emitting element.

[0157] When the emitted color of the light-emitting element selected by the user conforms to the first preset mapping relationship, that is, when it falls within the target emitted color range calculated according to the first preset mapping relationship, it means that the emitted color forms a high visual contrast with the ambient color. At this time, simply increasing the brightness of the light-emitting element appropriately according to the ambient brightness can ensure a clear display effect. At this time, the second preset mapping relationship satisfies: L2 = L1 + k1 * L1.

[0158] For example, if the environment in which the range hood is located is purple (λ1 = 380nm), and the target emission color determined according to the first preset mapping relationship is yellow-green with a center wavelength L2 = 565nm, when the user selects yellow or green emission color, it can be determined that the user is within the target emission color range. Therefore, the target emission brightness of the light-emitting element can be calculated according to the second preset mapping relationship L2 = L1 + k1 * L1. As another example, taking k1 = 2, when L1 = 10 lux and L2 = 30 lux, the brightness difference is 20 lux; when L1 = 20 lux and L2 = 60 lux, the brightness difference is 40 lux; and when L1 = 30 lux and L2 = 90 lux, the brightness difference is 60 lux. Thus, in this case, the target emission brightness of the light-emitting element increases with the increase of the ambient brightness, and the brightness difference between the two also increases slightly. This allows the light-emitting element to have a target emission brightness that differs significantly from the ambient brightness in brighter environments, thereby ensuring clear display.

[0159] When the emitted color of the user-selected light-emitting element does not conform to the first preset mapping relationship, that is, it does not fall within the target emitted color range calculated according to the first preset mapping relationship, it means that the emitted color cannot form a high visual contrast with the ambient color. In this case, the light-emitting element needs to significantly increase its brightness according to the ambient brightness to ensure a clear display effect. At this time, the second preset mapping relationship satisfies: L2 = L1 + k2 * L1 2 .

[0160] For example, if the environment in which the range hood is located is purple (λ1 = 380nm), and the target emission color determined according to the first preset mapping relationship is yellow-green with a center wavelength L2 = 565nm, then when the user selects blue or red emission color, it can be determined that the user is not within the target emission color range. Therefore, according to the second preset mapping relationship L2 = L1 + k2 * L1, the user can proceed. 2 The target luminance of the light-emitting element is calculated. For example, with k2 = 1, when L1 = 10 lux and L2 = 110 lux, the luminance difference is 100 lux; when L1 = 20 lux and L2 = 420 lux, the luminance difference is 400 lux; and when L1 = 30 lux and L2 = 930 lux, the luminance difference is 900 lux. Therefore, in this case, the target luminance of the light-emitting element increases with increasing ambient brightness, and the luminance difference between the two also increases significantly. This allows the light-emitting element to have a target luminance that differs greatly from the ambient brightness in brighter environments, thus ensuring clear display.

[0161] Figure 8This is a flowchart of another range hood control method provided by an embodiment of the present invention. This embodiment adds to the above embodiment "S310, during the operation of the range hood, detect the real-time ambient light brightness of the range hood.", specifically including: before S310,

[0162] Control the light-emitting element to light up at its initial brightness;

[0163] Before controlling the light-emitting element to illuminate at the target brightness based on the real-time ambient light level of the range hood, the following steps are also included:

[0164] The initial luminous intensity is determined to be less than the target luminous intensity, and the target luminous intensity is less than or equal to the maximum luminous intensity of the light-emitting element.

[0165] like Figure 8 As shown, the method includes:

[0166] S410, Control the light-emitting element to light up at the initial luminous brightness.

[0167] The initial luminous brightness can be understood as the luminous brightness value of the light-emitting element that is preset before the real-time ambient light brightness is detected and adjusted accordingly.

[0168] Specifically, after the range hood is turned on, before detecting the real-time ambient light level, the range hood is initially lit at its initial brightness to ensure that the user can interact with the range hood normally before the system starts collecting ambient light data and making precise adjustments.

[0169] S420. During the operation of the range hood, detect the real-time ambient light level of the range hood.

[0170] S430. Determine that the initial luminous brightness is less than the target luminous brightness, and the target luminous brightness is less than or equal to the maximum luminous brightness of the light-emitting element.

[0171] The maximum luminous brightness can be understood as the highest luminous intensity that the light-emitting element can achieve.

[0172] Specifically, during the operation of the range hood, the target luminous brightness is calculated based on the real-time ambient light level. If the initial luminous brightness is less than the target luminous brightness, it indicates that the current light brightness is insufficient to meet actual usage needs, and therefore the brightness of the light-emitting element needs to be adjusted. Simultaneously, it is also necessary to determine whether the target luminous brightness is less than or equal to the maximum luminous brightness of the light-emitting element. If the target luminous brightness exceeds the maximum luminous brightness, it indicates that even increasing the luminous brightness cannot meet actual usage requirements, and other strategies need to be adopted to ensure a better user experience.

[0173] S440: Based on the real-time ambient light level of the range hood, control the light-emitting element to illuminate at the target brightness.

[0174] This invention sets an initial luminous brightness, detects ambient light brightness in real time and adjusts accordingly, while ensuring that the brightness is within a reasonable range. This guarantees that users can interact immediately upon startup, and also makes the brightness change intelligently with the environment, thereby improving the user experience and product stability.

[0175] like Figure 4 As shown, in some embodiments, the panel assembly 20 further includes a frosted glass 25, which is located behind the transparent glass 21; a controller is electrically connected to the frosted glass 25 and is used to control the frosted glass 25 to switch from a transparent state to a frosted state. Based on this, Figure 9 This is a flowchart of another range hood control method provided by an embodiment of the present invention. Based on the above embodiment's step "S420, during the operation of the range hood, detect the real-time ambient light intensity of the range hood," an additional step has been added, specifically including: after S420,

[0176] When the target luminous brightness is greater than the maximum luminous brightness of the luminous element, the frosted glass is controlled to switch from a transparent state to a frosted state.

[0177] like Figure 9 As shown, the method includes:

[0178] S510, controls the light-emitting element to light up at the initial luminous brightness.

[0179] S520. During the operation of the range hood, detect the real-time ambient light level of the range hood.

[0180] S530. When the target luminous brightness is greater than the maximum luminous brightness of the luminous element, control the atomizing glass to switch from a transparent state to an atomized state.

[0181] Specifically, in the actual operation of a range hood, when the target luminous brightness calculated based on the real-time ambient light exceeds the maximum luminous brightness achievable by the light-emitting element, it indicates that relying solely on the brightness adjustment of the light-emitting element itself is insufficient to meet the user's need for clear visibility of the interface under the current environment. For example, in direct sunlight or other strong light environments, even if the light-emitting element emits light at maximum brightness, the interface may still be difficult to see due to strong light interference.

[0182] At this point, the control system will issue a command to switch the frosted glass from a transparent state to a frosted state. Using frosted glass with relatively low light transmittance as a background reduces the interference of strong light on the displayed content of the interface, thereby helping users see the information on the interface more clearly and improving the user experience.

[0183] In this embodiment of the invention, during the operation of the range hood, the ambient light intensity is detected, and when the target light-emitting brightness exceeds the maximum brightness of the light-emitting element, the frosted glass is switched to a frosted state. This effectively reduces strong light interference, ensures a clear and visible operating interface, and significantly improves the user experience.

[0184] Optionally, when the target luminance is greater than the maximum luminance of the light-emitting element, the frosted glass is controlled to switch from a transparent state to a frosted state, including:

[0185] When the target luminous brightness is greater than the maximum luminous brightness of the luminous element, the atomizing glass is controlled to switch from a transparent state to a target level of atomization; wherein, the target level of atomization has a third preset mapping relationship with the real-time ambient light brightness of the range hood.

[0186] The third preset mapping relationship can be understood as a pre-set rule between the real-time ambient light brightness of the range hood and the target atomization degree of the atomizing glass.

[0187] Specifically, the control system compares the calculated target luminous intensity with the maximum luminous intensity of the light-emitting element based on the real-time ambient light intensity. If the target luminous intensity is greater than the maximum luminous intensity, it indicates that the light-emitting element alone cannot meet the visibility requirements of the operating interface in the current environment, and the frosting function of the frosting glass is required. In this case, the control system determines the target frosting degree that the frosting glass should achieve based on a third preset mapping relationship. For example, if the current real-time ambient light intensity is detected at 900 lux, according to the preset mapping relationship, the target frosting degree is 40%.

[0188] Optionally, when the target luminance exceeds the maximum luminance of the luminous element, while controlling the frosted glass to switch from a transparent state to a frosted state, the following additional steps are also included:

[0189] Control the light-emitting element to light up at maximum brightness.

[0190] Specifically, while the control system determines the target atomization level that the atomizing glass should achieve based on the third preset mapping relationship, the control system sends a control command to the light-emitting element to emit light at maximum brightness, thereby realizing the coordinated control of the atomizing glass and the light-emitting element. This improves the visibility of the operating interface and the convenience of user operation under extreme ambient light conditions, providing users with a better user experience.

[0191] S540: Based on the real-time ambient light level of the range hood, control the light-emitting element to illuminate at the target brightness.

[0200] After this step is completed, proceed with S650.

This allows the range hood to quickly adapt to the environment upon initial startup, presenting the most suitable lighting effect, ensuring a clear and easy-to-read interface, and improving the user's initial experience.
