Technical Field
[0001] This invention relates to the field of air conditioner technology, and more specifically, to a control method, device, medium, and air conditioner for an air conditioner. Background Technology
[0002] Current research on air conditioner sterilization technology mainly focuses on sterilization of the air inside the air conditioner and in the surrounding environment. Furthermore, considering that users often engage in production and daily life in the environment, far-ultraviolet sterilization is difficult to apply to air conditioners.
[0003] Accordingly, this case provides a new control scheme for air conditioners to solve the above problems. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a control method for an air conditioner. The air conditioner includes a first air guide plate and a second air guide plate. A far-ultraviolet sterilization device is disposed on the second air guide plate. The far-ultraviolet sterilization device includes a light source unit for emitting far-ultraviolet light with a wavelength of 200 to 230 nm. The control method includes: in response to an instruction to activate the far-ultraviolet sterilization device, acquiring environmental information; determining a sterilization strategy based on the environmental information; and controlling the air conditioner according to the sterilization strategy to achieve sterilization treatment of the environment in which the air conditioner is located.
[0005] In related technologies, considering the potential harm of far-ultraviolet light to the human body, it is rarely used in air conditioners. Given the significant sterilization effect of far-ultraviolet light, this embodiment provides an air conditioner equipped with a far-ultraviolet sterilization device, and also provides a control method for this air conditioner. The far-ultraviolet sterilization device includes a light source unit for emitting far-ultraviolet light with wavelengths ranging from 200 to 230 nm; within this wavelength range, the absorption rate by human skin and eyes is very low, thus producing no side effects. In this technical solution, the far-ultraviolet sterilization device is installed on a second air guide plate, so the far-ultraviolet sterilization area can be determined by controlling the rotation angle of the second air guide plate, and the user can also determine the location of the sterilization area based on the wind direction.
[0006] Furthermore, the control method also includes: acquiring the temperature difference between the inner ring temperature and the set temperature, and issuing a command to turn on the far-ultraviolet sterilization device when the temperature difference is less than the temperature difference threshold.
[0007] The advantage of this technical solution is that, for air conditioners, cooling efficiency is the primary task. Therefore, the far-ultraviolet sterilization module is temporarily not activated when the indoor temperature has not yet dropped to the allowable threshold range. In other words, when the temperature difference is not lower than the temperature difference threshold, the user's need for cooling is given priority.
[0008] Furthermore, environmental information includes indoor microbial concentration; based on this environmental information, a sterilization strategy is determined; this includes determining the sterilization strategy based on the microbial concentration. The advantage of this technical solution is that, using the microbial concentration in the environment as an indicator, the sterilization efficiency can be adjusted according to the microbial concentration.
[0009] Furthermore, the sterilization strategy includes the movement strategy of the first and second air guide plates and the radiation intensity of the far-ultraviolet sterilization device; the sterilization strategy is determined based on the microbial concentration; including: determining the movement strategy of the first and second air guide plates and the radiation intensity of the far-ultraviolet sterilization device based on the microbial concentration.
[0010] The advantages of this technical solution are that the far-ultraviolet sterilization device is installed at the second air guide plate, and can be controlled according to the movement strategy of the first and second air guide plates, thereby achieving control over the sterilization area, working time, and other aspects of far-ultraviolet sterilization; on the other hand, the radiation intensity of the far-ultraviolet sterilization device can be adjusted according to the concentration of microorganisms, thus realizing a diverse sterilization strategy.
[0011] Furthermore, based on the microbial concentration, the movement strategy of the first and second air guide plates and the radiation intensity of the far-ultraviolet sterilization device are determined, including: when the microbial concentration is greater than the first concentration threshold X1, the first and second air guide plates are moved away from each other to the fully open position, the first air guide plate remains stationary, and the second air guide plate is rotated at a speed of A1, while the radiation intensity is controlled to be R1; when the microbial concentration is greater than the second concentration threshold X2 and less than the first concentration threshold X1, the first and second air guide plates are moved away from each other to the fully open position, the first air guide plate remains stationary, and the second air guide plate is rotated at a speed of A2, while the radiation intensity is controlled to be R2; when the microbial concentration is less than the second concentration threshold X2, the first and second air guide plates are moved away from each other to the fully open position, the first air guide plate remains stationary, and the second air guide plate is rotated at a speed of A3, while the radiation intensity is controlled to be R3; wherein, X1 > X2; A3 > A2 > A1; R1 > R2 > R3.
[0012] The advantage of this technical solution is that, when formulating a sterilization strategy, the higher the concentration of microorganisms, the slower the rotation speed of the second air guide plate and the greater the radiation intensity of the far-ultraviolet sterilization device. Therefore, the far-ultraviolet light irradiates the same area for a longer time and has a greater radiation intensity, achieving highly efficient sterilization.
[0013] Furthermore, the far-ultraviolet sterilization device also includes a filtering unit, which is used to selectively emit far-ultraviolet light with a wavelength of 222nm; the environmental information also includes the detection status of living organisms in the environment where the air conditioner is located; when the detection status indicates that there are living organisms in the environment where the air conditioner is located, the sterilization strategy is to control the filtering unit to work.
[0014] The advantage of this technical solution is that far-ultraviolet light with a wavelength of 222nm has a better sterilization effect. Therefore, when the presence of living organisms in the environment is detected, the control filter power supply is activated, so that the wavelength of the far-ultraviolet light emitted by the far-ultraviolet sterilization device is 222nm.
[0015] Furthermore, the control method also includes: controlling the far-ultraviolet sterilization device to turn off after a preset time has elapsed since the device was turned on.
[0016] The advantage of this technical solution is that it avoids the harm caused by continuously turning on the far-ultraviolet sterilization mode, such as excessive far-ultraviolet radiation.
[0017] The present invention also provides a control device for an air conditioner, wherein the air conditioner is equipped with a far-ultraviolet sterilization device. The control device includes: a determining module configured to acquire the operating status and environmental information of the air conditioner in response to an instruction to activate the far-ultraviolet sterilization mode; and a control module configured to control the far-ultraviolet sterilization device according to the operating status and environmental information of the air conditioner, so as to achieve sterilization treatment of the environment in which the air conditioner is located.
[0018] The present invention also provides a readable storage medium on which a program or instructions are stored, and when the program or instructions are executed by a processor, the steps of any of the above control methods are implemented.
[0019] The present invention also provides an air conditioner, wherein the air conditioner is provided with a far-ultraviolet sterilization device, and the air conditioner includes the above-mentioned control device; or the air conditioner can implement any of the above-mentioned control methods.

[0025] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] Example 1 See Figure 1 and Figure 2 A control method for an air conditioner, the air conditioner 100 including a first air guide plate 10 and a second air guide plate 20, the second air guide plate 20 being provided with a far-ultraviolet sterilization device 30, the far-ultraviolet sterilization device 30 including a light source unit for emitting far-ultraviolet light with a wavelength of 200 to 230 nm; the control method includes: S100: in response to an instruction to turn on the far-ultraviolet sterilization device 30, acquiring environmental information; S200: determining a sterilization strategy based on the environmental information; S300: controlling the air conditioner according to the sterilization strategy to achieve sterilization treatment of the environment in which the air conditioner is located.
[0027] In related technologies, considering the potential harm of far-ultraviolet light to the human body, it is rarely used in air conditioners. Given the significant sterilization effect of far-ultraviolet light, this embodiment provides an air conditioner equipped with a far-ultraviolet sterilization device, and also provides a control method for the air conditioner. The far-ultraviolet sterilization device 30 includes a light source unit for emitting far-ultraviolet light with wavelengths ranging from 200 to 230 nm; within this wavelength range, the absorption rate by human skin and eyes is very low, thus preventing side effects.
[0028] Furthermore, the control method includes the air conditioner responding to the instruction to turn on the far-ultraviolet sterilization device 30, and formulating a corresponding sterilization strategy based on environmental information, thereby controlling the air conditioner according to the sterilization strategy to achieve the removal of bacteria and microorganisms in the environment.
[0029] In step S100, the command to activate the ultraviolet sterilization device 30 varies depending on the specific application scenario. For example, it can be input via remote control buttons, where a far-ultraviolet sterilization button is set on the remote control, and the user enters the far-ultraviolet sterilization mode by pressing the button. Alternatively, it can be input via voice from a terminal device connected to the air conditioner, such as a mobile phone or Bluetooth speaker, where the user inputs a voice command, and the air conditioner activates the far-ultraviolet sterilization device 30 accordingly. After responding to the command, the air conditioner first obtains the environmental information of the current environment.
[0030] Furthermore, the control method also includes: acquiring the temperature difference between the inner ring temperature and the set temperature, and issuing a command to turn on the far-ultraviolet sterilization device 30 when the temperature difference is less than the temperature difference threshold.
[0031] In one specific implementation, the user can turn on the far-ultraviolet sterilization device 30 as needed, but considering the requirements for the air conditioner's cooling performance, it will not be activated immediately. After receiving the user's instruction, the system first obtains the temperature difference between the inner ring temperature and the set temperature. Only when the temperature difference is less than the temperature difference threshold will the system issue an instruction to turn on the far-ultraviolet sterilization device 30.
[0032] The reason for adopting the above solution is that, for air conditioners, cooling efficiency is the primary task. Therefore, the far-ultraviolet sterilization module is not turned on temporarily when the indoor temperature has not yet dropped to the allowable threshold range. Generally speaking, the temperature difference threshold is within 5℃, which can be 4℃, 3℃, 2℃, or 1℃.
[0033] On the other hand, in practical implementation, the cooling efficiency of the air conditioner is closely related to the angle and airflow pattern of the second air guide plate 20. Since the far-ultraviolet sterilization device 30 is installed at the second air guide plate 20, the sterilization strategy also involves controlling the second air guide plate 20; simply put, in this embodiment, the second air guide plate 20 includes both airflow guiding and far-ultraviolet light guiding functions. Therefore, when the temperature difference is not yet below the temperature difference threshold, the user's cooling needs are given priority.
[0034] Furthermore, environmental information includes indoor microbial concentration; based on the environmental information, a sterilization strategy is determined; including: determining a sterilization strategy based on microbial concentration.
[0035] In the above technical solution, the sterilization strategy is formulated based on the concentration of microorganisms in the environment. Since the control method provided in this embodiment targets the sterilization treatment of the air conditioner installation environment, the concentration of microorganisms in the environment is a very important indicator. Specifically, the device for detecting microorganism concentration can be installed at the air inlet, for example, to obtain the concentration of microorganisms in the environment by detecting indicators such as the number of bacterial colonies in the air at the air inlet. In a specific embodiment, the detection of microorganism concentration can also be performed by an external detection device. By communicating with the air conditioner, the air conditioner can obtain the concentration of microorganisms in the environment.
[0036] Furthermore, the sterilization strategy includes the movement strategy of the first air guide plate 10 and the second air guide plate 20, and the radiation intensity of the far-ultraviolet sterilization device 30; the sterilization strategy is determined according to the microbial concentration; including: determining the movement strategy of the first air guide plate 10 and the second air guide plate 20, and the radiation intensity of the far-ultraviolet sterilization device 30 according to the microbial concentration.
[0037] In this embodiment, the far-ultraviolet sterilization device 30 is installed at the second air guide plate 20. It can be controlled according to the movement strategy of the first air guide plate 10 and the second air guide plate 20, thereby realizing control over the sterilization area, working time and other aspects of far-ultraviolet sterilization. On the other hand, the radiation intensity of the far-ultraviolet sterilization device 30 can be adjusted according to the concentration of microorganisms, thus realizing a variety of sterilization strategies.
[0038] Furthermore, based on the microbial concentration, the movement strategy of the first air guide plate 10 and the second air guide plate 20, and the radiation intensity of the far-ultraviolet sterilization device 30 are determined, including: when the microbial concentration is greater than a first concentration threshold X1, the first air guide plate 10 and the second air guide plate 20 are controlled to move away from each other to the fully open position, the first air guide plate 10 remains stationary, and the second air guide plate 20 is controlled to rotate at a speed of A1, while the radiation intensity is controlled to be R1; when the microbial concentration is greater than a second concentration threshold X2 and less than a first concentration threshold X1, the first air guide plate 10 is ... the first concentration threshold X2, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X1, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X2, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X1, the third air guide plate 20 is controlled to rotate away from the first concentration threshold X2, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X1, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X2, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X1, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X2, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X1, the third air guide plate 20 is controlled to rotate away from the first concentration threshold X2, the second air guide plate 20 is controlled to rotate away from the first concentration threshold X1 After the first and second air guide plates 10 and 20 are moved away from each other to the fully open position, the first air guide plate 10 remains stationary, and the second air guide plate 20 is controlled to rotate at a speed of A2, while the radiation intensity is controlled to be R2. When the microbial concentration is less than the second concentration threshold X2, after the first and second air guide plates 10 and 20 are moved away from each other to the fully open position, the first air guide plate 10 remains stationary, and the second air guide plate 20 is controlled to rotate at a speed of A3, while the radiation intensity is controlled to be R3. Wherein, X1 > X2; A3 > A2 > A1; R1 > R2 > R3.
[0039] In this embodiment, when the far-ultraviolet sterilization device 30 is turned on, the indoor temperature is already close to the set temperature, thus entering the sterilization mode. At this time, the first air guide plate 10 and the second air guide plate 20 are first controlled to move away from each other to the maximum angle, so that in this mode, the angle of the first air guide plate 10 will not restrict the area of far-ultraviolet sterilization.
[0040] Considering that the heat exchange efficiency in the room is high when the air deflector is fully open, the fan speed can be adjusted according to different heat exchange modes.
[0041] In one specific implementation, the microbial concentration is compared with different thresholds. The first concentration threshold X1 and the second concentration threshold X2 are both preset values stored in the control module. When formulating the sterilization strategy, the higher the microbial concentration, the slower the rotation speed of the second air guide plate 20 and the higher the radiation intensity of the far-ultraviolet sterilization device 30. Therefore, the far-ultraviolet light irradiates the same area for a longer time and has a greater radiation intensity, achieving highly efficient sterilization.
[0042] Furthermore, the far-ultraviolet sterilization device 30 also includes a filtering unit, which is used to selectively emit far-ultraviolet light with a wavelength of 222nm; the environmental information also includes the detection status of living organisms in the environment where the air conditioner is located; when the detection status indicates that there are living organisms in the environment where the air conditioner is located, the sterilization strategy is to control the filtering unit to work.
[0043] In related technologies, when using far-ultraviolet (UV) sterilization, the typical UV wavelength is between 200-280 nm, with 253-257 nm wavelength UV light showing the best sterilization effect. However, considering the presence of living organisms in the air conditioner's installation environment, the UV sterilization device 30 in this embodiment emits a wavelength between 200-230 nm, which will not produce side effects on the human body. However, 222 nm wavelength UV light has a better sterilization effect. Therefore, when living organisms are detected in the environment, the filter power supply is controlled to operate, so that the wavelength of the UV light emitted by the UV sterilization device 30 is 222 nm.
[0044] Furthermore, the control method also includes: after the far-ultraviolet sterilization device 30 has been turned on for a preset time, controlling the far-ultraviolet sterilization device 30 to turn off.
[0045] In this embodiment, after the preset sterilization period, the far-ultraviolet sterilization device 30 can be turned off; simultaneously, the operation of the air conditioner remains unaffected. In one specific implementation, the preset duration can be half an hour, one hour, or other durations, which can be defined by the user according to actual needs. The advantage of adopting the above solution is that it avoids the hazards caused by continuously keeping the far-ultraviolet sterilization mode on, such as excessive far-ultraviolet radiation.
[0046] See Figure 3 The present invention also provides a control device 300 for an air conditioner, wherein the air conditioner is provided with a far-ultraviolet sterilization device 30. The control device includes: a determination module 310, which is configured to acquire the operating status and environmental information of the air conditioner in response to an instruction to activate the far-ultraviolet sterilization mode; and a control module 320, which is configured to control the far-ultraviolet sterilization device 30 according to the operating status and environmental information of the air conditioner, so as to achieve sterilization treatment of the environment in which the air conditioner is located.
[0047] See Figure 4 This is a schematic diagram of a readable storage medium provided in an embodiment of the present invention. The readable storage medium stores programs or instructions, which, when executed by a processor, implement the steps of any of the control methods described above. The readable storage medium 400 is, for example, a non-volatile memory, such as magnetic media (e.g., hard disks, floppy disks, and magnetic tapes), optical media (e.g., CD-ROMs and DVDs), magneto-optical media (e.g., optical discs), and hardware devices specifically configured for storing and executing computer-executable instructions (e.g., read-only memory (ROM), random access memory (RAM), flash memory, etc.). Computer-executable instructions 410 are stored on the readable storage medium 400. The readable storage medium 400 can be executed by one or more processors or processing devices to cause the air conditioner containing the readable storage medium 400 to implement the air conditioner control method as described in the first embodiment.
