Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a scene-based control method for an air conditioner brightness display mode and an air conditioner. Background Art

[0002] At present, the LED display control of air-conditioning equipment generally adopts fixed brightness or simple adjustment schemes. Among them, the fixed brightness scheme keeps the LED display screen at a constant brightness regardless of the ambient light intensity or the operating status of the air conditioner. This is not only dazzling when displayed at night, but also difficult for users to identify the display content in a strong light environment, resulting in a poor user experience. Some high-end models on the market use a simple adjustment scheme to achieve brightness adjustment through a photosensitive sensor, but only rely on a single parameter of ambient light, which can easily cause a mismatch between the display brightness and the functional status when the air conditioner operating mode is switched. For example, when a higher brightness prompt is required in the event of a fault alarm, the simple adjustment scheme still maintains a low brightness at night, which may pose a safety hazard.

[0003] The problem is that the current air-conditioning brightness control solution is not linked to the air-conditioning operation mode, resulting in a mismatch between the display brightness and the functional status when the mode is switched. Summary of the invention

[0004] The present invention solves the technical problem that the current air conditioner brightness control scheme is not linked with the air conditioner operation mode, resulting in the display brightness not matching the functional state when the mode is switched. The present invention implements multi-level adaptive control of the air conditioner brightness by designing a grading strategy for different scenarios.

[0005] To solve the above problems, the present invention provides a scene-based control method for an air conditioner brightness display mode, which is applied to an indoor unit, wherein the display brightness of the indoor unit includes one to a preset top level, wherein the preset top level brightness is the brightest and the first level brightness is the darkest; the scene-based control method comprises: within the first standard time when the indoor unit is turned on and operated, the display brightness of the display module on the indoor unit is displayed and operated according to the preset top level brightness; thereafter, at each first interval, the display brightness is reduced by one level until it is reduced to the second level brightness, and the second level brightness is maintained for continuous operation; if a fault signal is received during operation of the indoor unit, the display brightness of the display module is displayed and operated according to the preset top level brightness; at the same time, the display module flashes once at each second interval until the fault signal is removed and the display module is restored to the display brightness before the fault; if an energy-saving mode instruction is received during operation of the indoor unit, the display module is maintained at the current brightness of the first standard time, and then the display brightness is reduced to the second level brightness and continuously operated; if a sleep instruction is received during operation of the indoor unit, the display brightness of the display module is continuously operated according to the first level brightness; if a shutdown instruction is received during operation of the indoor unit, other indicator lights of the indoor unit are turned off, and the display brightness of the display module is continuously operated according to the first level brightness.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By presetting different display brightness levels, the display brightness can be flexibly adjusted according to different usage scenarios. This diverse brightness control can improve the user experience and meet the needs of different users. Among them, setting the standard operating time and interval mechanism makes the adjustment of the display brightness more automated, reduces the need for manual adjustment by users, and enhances the intelligence level of the air conditioner. Moreover, when a fault signal is received, the display module can automatically switch to the brightest preset top brightness and flash to prompt, which can effectively remind users to pay attention to the operating state of the air conditioner, facilitate users to handle faults in a timely manner, and increase the safety and reliability of the air conditioner. After receiving the energy-saving mode instruction, the display brightness can automatically decrease to the secondary brightness, which not only reduces energy consumption but also reflects the energy efficiency optimization of the device in terms of function, contributing to meeting the requirements of modern society for energy conservation and emission reduction. At the same time, after receiving the sleep instruction, the display module is kept at a lower brightness, which reduces the interference to users at night and enhances the user-friendly design of the product. After receiving the shutdown instruction, other indicator lights are turned off and the lowest brightness is maintained for operation, which helps to save energy consumption and can provide necessary standby information in the shutdown state. By setting the automatic adjustment mechanism in different scenarios, the operation complexity of users during use is reduced, making the use of the air conditioner more convenient, faster, and more adaptable.

[0007] In a possible design, the indoor unit includes a main control module; among them, the main control module can parse the operating state of the air conditioner in real time and adopt the hierarchical PWM duty cycle adjustment technology to adaptively control the display brightness of the indoor unit at multiple levels.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The main control module can parse the operating state of the air conditioner in real time, which means that the system can instantaneously adjust the display brightness according to the current working environment and user needs to achieve dynamic adaptation, increasing the intelligence level of the system. When a fault occurs, the main control module can quickly respond and adjust the display brightness to provide clear fault indication. Moreover, the hierarchical PWM duty cycle adjustment technology can perform fine adjustment among multiple brightness levels. Compared with the traditional simple switching or linear adjustment methods, it can achieve a smoother brightness change. This precise control significantly improves the display effect, making the display brightness more natural and comfortable. At the same time, by realizing the adaptive control of multiple levels of brightness, users can enjoy the best visual experience in different scenarios, which can enhance user satisfaction and comfort.

[0009] In a possible design, the indoor unit further includes a photosensitive sensor; after each startup and operation of the indoor unit, it obtains the ambient light intensity through the photosensitive sensor and updates the preset brightness threshold from level one to the preset top display brightness according to the recognition result; among them, the higher the value of the preset brightness threshold, the brighter the display brightness from level one to the preset top display brightness.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The introduction of the photosensitive sensor enables the air conditioner to automatically sense the ambient light intensity at startup and optimize the display brightness according to real-time data. Compared with a fixed brightness setting, this intelligent adjustment method can more precisely adapt to different environmental conditions, enhancing the flexibility and convenience of use. By automatically adjusting the display brightness according to environmental changes, users no longer need to manually intervene in the display settings, and it can ensure a comfortable visual experience under any lighting conditions. When the ambient light intensity is high, the display brightness is automatically increased to ensure visibility, and vice versa, which can effectively avoid unnecessary energy waste. This reasonable brightness adjustment can optimize energy consumption while maintaining the display effect. Moreover, by updating the preset brightness threshold, the system can more flexibly adjust the display effect according to different environmental situations, with stronger adaptability and better meeting the needs of different scenarios. In low-light environments, increasing the display brightness can ensure that the device status and warning information are clear at all times. This helps improve the safety of the device, making it easier for users to perceive important information or fault indications when using the air conditioner.

[0011] In a possible design, the preset brightness threshold corresponds to the drive current, and the higher the value of the preset brightness threshold, the greater the drive current; wherein, the indoor unit dynamically adjusts the duty cycle of the PWM signal through software to control the drive current of the display module.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By directly associating the preset brightness threshold with the drive current, more delicate adjustment of the display brightness can be achieved. With the change of the preset brightness threshold, the adjustment of the drive current can enable the display module to maintain a consistent visual effect under different ambient light conditions. Software control of the duty cycle of the PWM signal enables the system to respond to environmental changes in real time, and the automatic adjustment of the light intensity can be more flexible and efficient. Through precise current adjustment, the display module can emit light more stably and evenly at the selected brightness, avoiding problems such as flicker and uneven brightness, thus significantly improving the user's visual experience.

[0013] In a possible design, if the photosensitive sensor is not enabled or fails, the indoor unit uses the preset brightness threshold set by default to execute the display brightness from one to the preset top level.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By setting a default preset brightness threshold, the indoor unit can always remain in an available state regardless of the status of the photosensitive sensor. This improves the overall reliability of the system and reduces the situation of degraded user experience or unavailability caused by sensor failures.

[0015] In a possible design, every time after the first interval of time, the display brightness decreases by one level until it reaches the second-level brightness, and then the second-level brightness is maintained and the operation continues. It also includes: during the operation of the indoor unit, if a control signal from a remote control or a button is received, the display brightness of the display module is reset to the preset top-level brightness, and then every time after the first interval of time, the display brightness decreases by one level until it reaches the second-level brightness, and then the second-level brightness is maintained and the operation continues.

[0016] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By gradually reducing the brightness, it can effectively reduce energy consumption, extend the service life of the display module, and reduce the overall power consumption. This way of dynamically adjusting the brightness can achieve the purpose of energy conservation while maintaining a certain visibility. At the same time, by adopting the function of automatically returning to the top-level brightness, users can obtain the best visual effect when needed. Especially in scenarios with dim light or when detailed viewing is required, quickly restoring to the top-level brightness can enhance the user experience under temporary needs.

[0017] In a possible design, during the operation of the indoor unit, if multiple brightness adjustment instructions are received, the last received valid instruction is used as the execution basis.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By following the last received valid instruction for execution, the system ensures that the latest changes in user requirements are given priority. This can effectively avoid unnecessary confusion caused by excessive instructions, making the user operation have a clear priority and enhancing the intuitiveness of the operation. At the same time, by adopting the design of giving priority to the last instruction, the control logic of the system is clearer and simpler. No matter how many times the user issues brightness adjustment instructions, the system only needs to process the last valid instruction, thereby reducing the processing complexity, improving the system response speed and processing efficiency. And when multiple brightness adjustment instructions are issued simultaneously, it may cause the display module to confuse the execution order. By only executing the last valid instruction, it can reduce the troubles caused by misoperations and provide a more stable user experience.

[0019] In a possible design, during the operation of the indoor unit, the priority of the fault signal is the highest. If the fault signal and other detection signals or instructions appear simultaneously, the processing method of the fault signal is preferentially executed.

[0020] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Prioritizing the execution of fault signal processing can promptly respond to potential safety hazards and prevent accidents from occurring. It ensures that immediate measures can be taken when the device fails, such as stopping the device operation or issuing an alarm, thereby protecting the safety of users and the device. At the same time, by ensuring that the fault signal has the highest priority, the system can better maintain its stability. When a fault occurs, it will not be interfered by other functions or instructions, resulting in a more reliable operating state. In a fault state, if other non-emergency instructions are confirmed for processing, it may affect the repair of the fault. Prioritizing the processing of fault signals can effectively avoid instruction conflicts and ensure that the device can quickly return to the normal state.

[0021] In a possible design, when the display module switches the brightness level, after the switched brightness level has been running for at least a third interval time, it can then be switched to other brightness levels.

[0022] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Frequent brightness switching may cause screen flickering, which not only makes users feel uncomfortable but also may reduce the service life of the display module. Setting a minimum running time interval can effectively avoid this discomfort and improve the user experience. At the same time, compared with instantaneous brightness changes, a given running time interval allows for smoother brightness switching, which not only makes the visual experience more gentle but also enables users to more naturally adapt to brightness changes in different environments.

[0023] The present invention also provides an air conditioner that implements a method for controlling different scenarios of the air conditioner brightness display mode.

[0024] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The air conditioner of the present invention implements the method for controlling different scenarios of the air conditioner brightness display mode of any technical solution of the present invention. Therefore, it has all the beneficial effects of the method for controlling different scenarios of the air conditioner brightness display mode of any technical solution of the present invention, which will not be elaborated here.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] See also Figures 1 to 6 The present invention provides a scene-based control method for an air conditioner brightness display mode, which is applied to an indoor unit. The display brightness of the indoor unit includes a preset top level, wherein the preset top level brightness is the brightest and the first level brightness is the darkest. The scene-based control method includes: During the first standard time when the indoor unit is turned on, the display brightness of the display module on the indoor unit runs at the preset top brightness; thereafter, at each first interval, the display brightness is reduced by one level until it is reduced to the second level, and then the second level brightness is maintained for continuous operation; if a fault signal is received during the operation of the indoor unit, the display brightness of the display module is displayed and runs at the preset top brightness; at the same time, it flashes once at each second interval until the fault signal is removed and the display module is restored to the display brightness before the fault; if the indoor unit receives an energy-saving mode instruction during operation, the display module maintains the current brightness for the first standard time, then reduces the display brightness to the second level, and continues to run; if the indoor unit receives a sleep instruction during operation, the display brightness of the display module is continuously operated at the first level; if the indoor unit receives a shutdown instruction during operation, the other indicator lights of the indoor unit are turned off, and the display brightness of the display module is continuously operated at the first level.

[0028] Specifically, in this embodiment, the display brightness of the indoor unit includes levels one to five, wherein level five is the brightest and level one is the darkest. In other embodiments, the preset top brightness of the display brightness can be adjusted according to the specific actual scene. In this embodiment, the first standard time is five minutes; the first interval time is one hour; the second interval time is one second; within five minutes of the indoor unit starting up, the display brightness of the display module on the indoor unit runs at level five brightness. Within five minutes of starting up, the user needs to set and confirm the air conditioner operation status, and has high requirements for the display brightness. Setting the level five brightness operation can ensure the user's visibility of the display module. After that, the display brightness of the display module is reduced by one level every hour until it is reduced to level two brightness; this can reduce energy consumption and reduce the impact of the display brightness on the user. When the indoor unit receives a fault signal, the display brightness of the display module runs at level five brightness, and at the same time, it flashes once every one second until the fault signal is cleared. When the indoor unit receives an energy-saving mode instruction, the display module maintains the current brightness for five minutes, then directly reduces the display brightness to level two brightness, and continues to run. When the indoor unit receives a shutdown command, other display lights of the indoor unit are turned off, leaving only the standby light of the display module to operate at the first-level brightness display.

[0029] In one embodiment of the present application, the indoor unit includes a main control module; wherein the main control module can analyze the operating status of the air conditioner in real time, and adopt a hierarchical PWM duty cycle adjustment technology to adaptively control the display brightness of the indoor unit in multiple levels.

[0030] Specifically, in this embodiment, the main control module (MCU) can analyze the operating status of the air conditioner in real time, and control the display module to display different levels of display brightness according to different operating states, including cooling, heating, energy saving, fault alarm, etc. Among them, the hierarchical PWM (Pulse Width Modulation) duty cycle adjustment technology is a method of adjusting parameters such as the average power or brightness of the output signal by setting different duty cycles using the principle of pulse width modulation. In this embodiment, the hierarchical PWM duty cycle adjustment technology divides the duty cycle into several levels. For example, 8 different duty cycle levels (0%, 12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5%, 100%) can be defined, and each level corresponds to different output power and brightness. This method allows the main control module to control the display brightness more finely when controlling the display module. In addition, through multiple duty cycle levels, more detailed and smooth output adjustment can be achieved, so that users can get a better user experience.

[0031] In an embodiment of the present application, the indoor unit further includes a photosensitive sensor; after each startup and operation of the indoor unit, the environmental light intensity is obtained through the photosensitive sensor, and a preset brightness threshold for updating the first to preset top display brightness levels is updated according to the recognition result; among them, the higher the value of the preset brightness threshold, the brighter the first to preset top display brightness levels are.

[0032] Specifically, in this embodiment, the main control module performs multi-level adaptive control on the display brightness of the display module on the indoor unit by combining the operating state of the air conditioner and the photosensitive sensor. Among them, preset brightness thresholds are correspondingly set for the first to fifth-level display brightness levels. The higher the value of the pre-reviewed brightness threshold, the brighter the corresponding level of display brightness is. After each startup of the indoor unit, the environmental light intensity will be obtained through the photosensitive sensor, and the preset brightness threshold will be mapped and updated according to the recognition result. For example, in a strong light environment during the day, the preset brightness threshold will be updated to a higher value, so that the display brightness of the display module is brighter, ensuring the visibility of the user; similarly, in a weak light environment at night, the preset brightness threshold will be updated to a lower value, so that the display brightness of the display module is darker, ensuring that it will not affect the sleeping user.

[0033] In an embodiment of the present application, the preset brightness threshold corresponds to the drive current, and the higher the value of the preset brightness threshold, the larger the drive current; among them, the indoor unit dynamically adjusts the duty cycle of the PWM signal through software to control the drive current of the display module.

[0034] Specifically, in this embodiment, the preset brightness threshold corresponds to the drive current, and the display module of the indoor unit uses an LED lamp as the display light source. Different preset brightness thresholds correspond to different drive currents, and the higher the preset brightness threshold, the larger the corresponding drive current. Among them, within the rated current range of the LED lamp, the larger the drive current, the brighter the display brightness of the LED lamp. Therefore, by setting different preset brightness thresholds for each display brightness level in different light environments, the display module can maintain a consistent visual effect in different environmental lightings, allowing users to see the content of the display module clearly and gently whether during the day or at night.

[0035] In an embodiment of the present application, if the photosensitive sensor is not enabled or fails, the indoor unit uses the preset brightness threshold set by default to execute the display brightness from the first to the preset top level.

[0036] Specifically, in this embodiment, preset brightness thresholds for the first to fifth-level display brightness levels are default set in the main control module. When the photosensitive sensor is damaged and fails, the main control module cancels the update of the preset brightness threshold and uses the preset brightness threshold set by default in the system. And if a photosensitive sensor is not set in the air conditioner, the main control module only uses the preset brightness threshold set by default in the system to control the display brightness of the display module and does not perform the operation of updating the preset brightness threshold.

[0037] In one embodiment of the present application, after each interval of the first interval time, the display brightness is reduced by one level until it reaches the secondary brightness level, and then the secondary brightness level is maintained for continuous operation. It further includes: during the operation of the indoor unit, if a control signal from a remote control or a button is received, the display brightness of the display module is reset to the preset top brightness level, and then after each interval of the first interval time, the display brightness is reduced by one level until it reaches the secondary brightness level, and then the secondary brightness level is maintained for continuous operation.

[0038] Specifically, in this embodiment, if the indoor unit receives a control signal from a remote control or a button during operation, it means that the user is adjusting the display mode or the operating state of the air conditioner. At this time, the main control module will control the display brightness of the display module to be reset to the five-level brightness level again, and every hour, the display brightness is reduced by one level until the display brightness reaches the secondary brightness level, and then the display module maintains the secondary brightness level for continuous operation. Among them, resetting to the five-level brightness level again after receiving the control signal is to provide the user with clear and bright display content so that the user can know the current operating state of the air conditioner.

[0039] In one embodiment of the present application, during the operation of the indoor unit, if multiple brightness adjustment instructions are received, the last valid instruction received is used as the execution basis.

[0040] Specifically, in this embodiment, if the indoor unit receives multiple brightness adjustment instructions within a short period of time during operation, to prevent confusion in brightness adjustment, the indoor unit uses the last valid instruction received as the execution basis to control the display brightness of the display module, so as to ensure that the user's latest control requirements are executed.

[0041] In one embodiment of the present application, during the operation of the indoor unit, the priority of the fault signal is the highest. If the fault signal and other detection signals or instructions appear simultaneously, the fault signal processing method is preferentially executed.

[0042] Specifically, in this embodiment, the priority of the fault signal is the highest under any circumstances, and the fault signal needs to be responded to first. If multiple brightness adjustment instructions are received within a short period of time, even if the fault signal is not the last valid instruction received, the fault signal processing method should be preferentially executed. To ensure that the user can receive the fault information of the air conditioner, promptly handle the fault, and prevent the safety of the user and the equipment from being affected due to untimely fault handling.

[0043] In one embodiment of the present application, when the display module switches the brightness level, the switched brightness level should run for at least the third interval time before it can be switched to other brightness levels.

[0044] Specifically, in this embodiment, the third interval time is ten seconds. To avoid discomfort to the user caused by sudden changes in display brightness, after the switched brightness level has been running for at least ten seconds, it can be switched to other brightness levels.

[0045] The present invention also provides an air conditioner, and the air conditioner implements a sub-scenario control method for the air conditioner brightness display mode.

[0046] Specifically, the air conditioner of the present invention implements the sub-scenario control method for the air conditioner brightness display mode of any technical solution of the present invention. Therefore, it has all the beneficial effects of the sub-scenario control method for the air conditioner brightness display mode of any technical solution of the present invention, which will not be elaborated here.

[0047] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
