[0003] When a sudden increase in indoor particulate matter concentration is detected, the air purifier will quickly and significantly increase its purification power for strong purification. However, quickly and significantly increasing its own purification power will cause a great load and impact on the motor and transmission device in the air purifier, accelerating their mechanical wear. Frequent and rapid increases in purification power will shorten the service life of the motor and fan in the air purifier. Summary of the invention

[0004] The present application provides a control method, device, equipment and storage medium for an air purifier, which are used to quickly respond and optimize the purification process when the indoor particulate matter concentration suddenly increases, thereby improving the purification effect and protecting the equipment and extending its service life.

[0005] In a first aspect, the present application provides a control method for an air purifier, the control method for the air purifier comprising: if within a preset time period, when it is detected that the concentration of target particle matter in the target area is greater than a threshold value, calculating a first purification power of the air purifier according to the target particle matter concentration; determining a first time period for adjusting the current purification power of the air purifier to the first purification power, and determining a second time period for maintaining the operation of the first purification power; generating a control instruction according to the first purification power, the first time period and the second time period, so that the air purifier reduces the target particle matter concentration in the target area according to the control instruction.

[0006] By adopting the above technical solution, the air purifier control method can detect the change of indoor target particle concentration, respond quickly when the concentration exceeds the threshold, and calculate the reasonable first purification power under the current environment. The method sets a first duration for smoothly increasing the current power to the first purification power, which can prevent the impact on the equipment.

[0008] By adopting the above technical solution, the method of calculating the first purification power according to the user-set mode realizes user participation in control, can balance the purification effect and energy-saving requirements, and make the control method more intelligent and friendly. Users can choose the operating mode of the air purifier according to their needs, and the device can adjust the purification strategy according to the mode setting, which improves human-computer interactivity and user experience.

[0010] By adopting the above technical solution, the control method adds a step of comprehensively determining the power according to the air purifier operation mode set by the user when calculating the first purification power. When the user selects the power saving mode, a lower first purification power will be calculated according to the current concentration. In the power saving mode, the basic purification effect can be achieved at a lower power, thus achieving energy saving.

[0011] Optionally, the operating mode of the air purifier includes a fast mode, and the first purification power of the air purifier is calculated in combination with the operating mode of the air purifier set by the user end and the target particle matter concentration, including: if the operating mode of the air purifier set by the user end is the fast mode, then obtaining the maximum purification power of the air purifier, and using the maximum purification power as the first purification power.

[0012] By adopting the above technical solution, the control method adds a step of comprehensively determining the power according to the air purifier operation mode set by the user when calculating the first purification power.

In this way, different first purification powers can be calculated according to the user's usage needs and preferences, and the maximum power can be used for fast purification in the fast mode.

[0013] Optionally, determining the first time required to adjust the current purification power of the air purifier to the first purification power includes: obtaining a preset power increase rate of the air purifier; and determining the first time required to adjust the current purification power of the air purifier to the first purification power in combination with the preset power increase rate and the first purification power.

[0014] By adopting the above technical solution, the preset power rise speed parameter of the air purifier is obtained, and the time required for a smooth transition is calculated by combining the rise speed with the first purification power, which can prevent the power from jumping instantly and causing a large impact burden on the equipment. The power rises steadily at a preset rate, reducing damage to the motor and transmission device.

[0015] Optionally, determining the second time length for maintaining operation at the first purification power includes: obtaining a target concentration of target particles in the target area; calculating the difference between the target concentration of target particles in the target area and the current concentration of target particles in the target area to obtain a concentration to be reduced; calculating a first concentration at which the concentration of target particles in the target area decreases when the current purification power of the air purifier is increased to the first purification power; calculating a second concentration at which the concentration of target particles in the target area decreases when the air purifier is reduced from the first purification power to the current purification power; obtaining a third concentration by combining the concentration to be reduced, the first concentration and the second concentration; and determining the second time length for maintaining operation at the first purification power based on the third concentration.

[0016] By adopting the above technical solution, when determining the second duration of maintaining the first purification power, the method adds a step to calculate the accurate purification time based on the target concentration, current concentration, and concentration change rate. Specifically, the target concentration is detected, the difference with the current concentration is calculated, that is, the concentration to be reduced, and then the concentration changes when the power is increased and decreased are calculated respectively, and the accurate third concentration that needs to be continuously purified is comprehensively calculated, and finally the second duration is calculated based on the third concentration. By calculating the purification time, a reasonable purification duration can be intelligently determined, making the air purification process more accurate and efficient, achieving better purification effects while also taking energy efficiency into consideration.

[0017] Optionally, after generating the control instruction according to the first purification power, the first duration and the second duration, it also includes: if it is detected that the operating time of the air purifier exceeds the set time, an alarm message is sent to the user terminal to enable the user to adjust the air purifier.

[0018] By adopting the above technical solution, a detection of the purifier's operating time is set. When it is detected that the real-time operating time exceeds the preset safety threshold, the controller will automatically generate an alarm message and send it to the user terminal to remind the user that the air purifier has been running continuously for a long time and needs timely maintenance. It can avoid mechanical failure problems that may be caused by long-term continuous operation and realize real-time monitoring of the equipment's operating status.

The method sets a first duration for smoothly increasing the current power to the first purification power, which can prevent the impact on the equipment. The second duration is calculated to dynamically control the purification time according to the concentration change, which can purify efficiently and avoid excessive processing. By generating a control instruction that integrates the power and duration parameters, the air purifier can be guided to operate smoothly, efficiently and intelligently.

[0030] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0031] In the description of the embodiments of the present application, words such as "illustrative", "for example" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "illustrative", "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "illustrative", "for example" or "for example" is intended to present related concepts in a concrete way.

[0032] Air purifiers are mainly used to purify indoor air and can remove various pollutants in the air. Some of the substances that air purifiers often need to deal with include: particulate matter, including PM2.5 and PM10, which are the main pollutants that air purifiers need to remove; harmful gases in the air, such as formaldehyde, benzene, radon, ammonia, secondhand smoke, etc.; biological pollutants in the air, such as bacteria, viruses, mold, pollen, etc.; remove various odors in the air, such as smoke, pet odor, kitchen odor, etc.

[0033] For ease of explanation, the concentration of particulate matter in the air is used as an example. When the air purifier is running at a certain operating power, the concentration of particulate matter in the air may increase suddenly due to unexpected situations. For example, when cleaning the room or moving furniture, a lot of dust may be stirred up, resulting in a sudden increase in the concentration of particulate matter, poor outdoor air quality (such as haze), and opening windows for ventilation may cause a sudden increase in the concentration of particulate matter indoors. When the indoor particulate matter concentration increases suddenly, the air purifier needs to increase the operating power of the air purifier based on the existing operating power. When the particle concentration is reduced, the operating power is reduced again so that the air purifier operates at the initial operating power.

[0034] In the prior art, when the concentration of particulate matter increases suddenly, the air purifier will directly increase the operating speed significantly. When the air purifier reduces the concentration of particulate matter to the preset standard, it will directly reduce the operating speed to the initial operating speed. Large adjustments to the operating power of the air purifier may cause unnecessary pressure on the motor and other mechanical parts of the device, thereby shortening the life of the device. If the air purifier frequently switches between high and low power, it may also increase energy consumption.

[0035] Therefore, in response to the above problems, this application proposes a solution. When the concentration of particulate matter in the indoor air increases suddenly, the operating power of the air purifier can be stably adjusted to avoid drastically adjusting the operating power of the air purifier, thereby generating unnecessary pressure on the motor and other mechanical components of the equipment, thereby shortening the life of the equipment. It should be noted that the air purifier will not slowly increase the power in all cases. The user can set it according to the actual situation. For example, the user may urgently need to reduce the indoor particulate matter concentration. At this time, the air purifier will quickly increase the self-rising operating power to achieve a rapid purification effect; the specific situation depends on the actual situation, and no more details will be given here.

[0036] Figure 1 is a flow chart of a control method of an air purifier provided in an embodiment of the present application. It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but the steps are not necessarily executed in the order indicated by the arrows; unless otherwise specified in this document, there is no strict order restriction for the execution of the steps, and the steps may be executed in other orders; and Figure 1 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0037] The present application discloses a control method for an air purifier. Figure 1 As shown, the method includes S101-S103.

[0038] S101, if it is detected that the concentration of target particles in the target area is greater than a threshold value within a preset time period, a first purification power of the air purifier is calculated according to the concentration of the target particles.

[0039] In one example, the target area here can be any area. Generally speaking, the air purifier is usually used indoors. When the air purifier is started, it will monitor the indoor particle concentration in real time to keep the indoor particle concentration below a certain concentration to avoid harm to the human body. When users clean the room or move furniture, they may stir up a lot of dust, resulting in a sudden increase in particle concentration or poor outdoor air quality (such as haze). Opening windows for ventilation will cause a sudden increase in indoor particle concentration. When a sudden increase in indoor particle concentration is detected, the air purifier will increase the operating power to eliminate the indoor particle concentration so that the indoor particle concentration is below a certain concentration.

[0040] When the air purifier is running, it will detect the indoor particle concentration in real time. If the particle concentration is detected to have increased significantly within the preset time, that is, it exceeds the preset concentration change ratio, for example, more than twice the previous one, the preset time here can be set according to the actual situation. When the particle concentration is detected to have increased significantly within the preset time, the operating power that the current air purifier needs to reach is determined, and the indoor particle concentration is reduced by the operating power. The operating power that the air purifier needs to reach here is the first purification power.

[0041] Calculating the first purification power of the air purifier according to the target particle concentration includes: responding to the operating mode of the air purifier set by the user end, combining the operating mode of the air purifier set by the user end and the target particle concentration, and calculating the first purification power of the air purifier.

[0042] In one example, for a general air purifier, there are two operating modes. One mode is the power saving mode, which can be understood as the minimum operating rate required to purify the current indoor particle concentration. Following this minimum operating rate can save electric energy, but the purification speed of this minimum operating rate is slow; the other is the fast mode, which can be considered the fastest operating rate that the current air purifier can reach. At the fastest operating rate, the air purifier can purify the current indoor particle concentration as quickly as possible, but it will also consume a lot of electricity.

[0043] When using the air purifier, the user can customize the operating mode of the air purifier. Of course, the user can also set the minimum and maximum operating speed of the air purifier by himself. Here he can set it according to the actual situation.

[0044] If the operation mode of the air purifier set by the user is the power saving mode, the minimum purification power of the air purifier for purifying the current target particle size concentration is determined according to the target particle size concentration, and the minimum purification power is used as the first purification power.

[0045] When the user selects "power saving mode" on the user terminal of the air purifier, the air purifier needs to calculate the minimum purification power for purifying the current target particle concentration as the first purification power. In power saving mode, the air purifier should achieve the basic purification effect with the lowest possible power, which can ensure the purification effect and save energy.

[0046] Specifically, the concentration of particles in the target area is detected in real time, and the detection data is sent continuously. According to the set power saving mode algorithm, the minimum purification power required to purify the current target particle concentration is calculated. The power saving mode algorithm will pre-establish a mathematical model based on the hardware parameters of the air purifier. These parameters include the fan power range, motor rated power, the correspondence between air volume and power, etc. The model also considers the size of the target area, and different areas correspond to different power requirements. As well as the characteristics of different types of particles, such as particle size, density, etc., which affect the difficulty of removal. During operation, the type and concentration of the target particles are detected in real time, and brought into the model for calculation. The model calculates the theoretical minimum power required to achieve the basic purification effect under the current environment, and then considers factors such as model errors and environmental dynamic changes to determine the actual operating power that is slightly higher than the theoretical minimum power.

[0047] The first purification power calculated in this way can basically achieve the effect of removing particulate matter and is the minimum power under current conditions. This can achieve the effect of purifying air quality with the lowest possible energy consumption in power saving mode, saving energy, while also reducing the load on the equipment motor and extending its service life.

[0048] If the operation mode of the air purifier set by the user end is the fast mode, the maximum purification power of the air purifier is obtained, and the maximum purification power is used as the first purification power.

[0049] Specifically, when the user selects "fast mode" on the user terminal of the air purifier, the air purifier needs to purify the air quickly. In the fast mode, the first purification power of the air purifier is set to its maximum purification power. The controller of the air purifier first retrieves the maximum purification power parameter stored in the internal memory of the air purifier. The maximum purification power parameter has been determined according to the mechanical structure, motor power, etc. of the air purifier at the factory and written into the memory. The controller directly reads the maximum purification power value in the memory and uses the value as the first purification power in the fast mode. By directly using the maximum purification power as the first purification power, the air purifier can quickly reach the highest purification rate in the fast mode and quickly purify the indoor air.

[0050] It should be noted that both the fast mode and the power saving mode can be set according to actual conditions. For example, in the fast mode, the user can set the maximum operating power by himself. The maximum operating power set by himself can be less than the maximum purification power value in the memory. The specific value can be determined according to actual conditions and will not be elaborated here.

[0051] S102, determining a first time length for adjusting the current purification power of the air purifier to the first purification power, and determining a second time length for maintaining the operation of the first purification power.

[0052] In one example, the first duration refers to the time required to smoothly increase the current purification power of the air purifier to the calculated first purification power. The calculation method of the first duration may include calculating the difference between the current purification power and the first purification power, dividing it by the preset air purifier power smooth rise and fall rate parameter, and obtaining the theoretical rise time as the first duration. The calculation method of the second duration may include the time required for the air purifier to continue to run at the first purification power to reach the target purification concentration. Calculation method: detect or obtain the target purification concentration value, and calculate the difference between the current concentration and the target value. Based on the concentration reduction rate at the first purification power, calculate the theoretical time required to reach the target concentration, and adjust the second duration. Here, the first duration focuses on reflecting the time characteristics of the smooth rise and fall of the air purifier power, and the calculation method is based on the power difference and the rise and fall rate parameters. The second duration focuses on reflecting the time to achieve the purification target by continuous operation at high power, and the calculation method is based on the target concentration, current concentration and purification rate.

[0053] After calculating the first purification power, the air purifier needs to determine the time required to smoothly increase the current purification power to the first purification power, that is, the first time. The reason for calculating the first time is that directly increasing the power significantly will cause losses to the motor and machinery, and the power needs to be increased steadily and gradually. At the same time, it is also necessary to calculate the second time to maintain high power operation in order to continue to purify until the air quality meets the standard.

[0054] The specific calculation method is that the controller of the air purifier first uses a simple linear relationship to calculate the theoretical time required to increase the current power to the first purification power based on the difference between the current purification power and the calculated first purification power, as well as the preset power smooth increase and decrease rate parameter, as the first duration. The power increase and decrease rate here is preset in consideration of the motor load characteristics.

[0055] The controller then calculates the second duration of high-power operation by first detecting or accepting the target purification concentration value set by the user, and then measuring the difference between the current actual concentration and the target value. Based on the purification rate at the first purification power, the theoretical time required to reach the target concentration at the first power is calculated, and then the second duration is determined in combination with possible environmental dynamic changes and other factors.

[0056] By calculating the first duration and the second duration, the air purifier can smoothly increase the power and continue to run for a period of time, which can not only avoid motor overload, but also efficiently purify the air, achieving the effect of quickly purifying the air quality.

[0057] Determine a first time duration required to increase a current purification power of an air purifier to a first purification power, including: obtaining a preset power increase rate of the air purifier; and determining a first time duration required to increase the current purification power of the air purifier to the first purification power in combination with the preset increase rate and the first purification power.

[0058] In one example, in order to prevent the air purifier from causing damage to mechanical equipment when increasing power, it is necessary to calculate a process of smoothly increasing power. Specifically, the controller of the air purifier first obtains the power smooth increase rate parameter stored in the controller memory. This parameter takes into account the motor load characteristics and is determined at the factory based on the motor rated power, torque characteristics, etc. The controller then uses the current purification power, the calculated first purification power, and the preset rise rate parameter to calculate the time required to smoothly increase the current power to the first purification power through a simple linear relationship as the first duration. This allows the power to increase slowly along a stable slope to prevent overload damage to the motor and transmission device. By pre-configuring the power rise rate parameters and calculating the first duration required to smoothly increase the power during operation, the air purifier can achieve a smooth increase in power, which can not only achieve the effect of rapid purification, but also protect the mechanical structure of the equipment and extend its service life.

[0059] Determining a second time length for maintaining operation at a first purification power includes: obtaining a target concentration of target particles in a target area; calculating a difference between the target concentration of target particles in the target area and the concentration of target particles in a current target area to obtain a concentration to be reduced; calculating a first concentration at which the concentration of target particles in the target area is reduced when the current purification power of the air purifier is increased to the first purification power; calculating a second concentration at which the concentration of target particles in the target area is reduced when the air purifier is reduced from the first purification power to the current purification power; obtaining a third concentration by combining the concentration to be reduced, the first concentration, and the second concentration; and determining a second time length for maintaining operation at the first purification power based on the third concentration.

[0060] In one example, in order to calculate the continuous operation time required at the first purification power to achieve the purification target, the second duration needs to be calculated. The specific calculation method is that the controller of the air purifier first detects or obtains the target purification concentration set by the user, and then detects the current actual concentration, and calculates the difference between the two, that is, the concentration to be reduced. Then, based on the concentration reduction rate at the first purification power, the concentration that can be reduced at this power is calculated, that is, the first concentration. At the same time, the value of the concentration rebound when it falls back to the original power is also calculated, that is, the second concentration. Combining the first concentration, the second concentration and the concentration to be reduced, the third concentration that needs to be reduced at high power can be obtained, so that the second duration required to meet the standard can be calculated based on the concentration reduction rate of the first purification power. In this way, the time required for continuous purification can be accurately calculated.

[0061] By obtaining the target concentration and calculating the concentration values ​​at different powers and concentration change rates, the air purifier can scientifically and reasonably calculate the second time required to continuously run at the first purification power to achieve the purification target. This can ensure that the air quality is fully purified to meet the standard.

[0062] S103: Generate a control instruction according to the first purification power, the first duration, and the second duration, so that the air purifier reduces the target particle concentration in the target area according to the control instruction.

[0063] In one example, after calculating the first purification power, the first duration required to smoothly increase the current power to the first purification power, and the second duration required to continuously run at the first purification power to reach the purification target, it is necessary to generate a final control instruction to guide the air purifier to operate according to the calculated parameters. Specifically, the controller of the air purifier integrates the calculated first purification power, the first duration, and the second duration to generate a set of control parameters. Then, based on these control parameters, the controller generates detailed control instructions for controlling the air purifier motor, fan and other actuators. These control instructions will include the value of the first purification power, the time series for gradually increasing the power to the first purification power, and the specific time for continuous operation at the first purification power. Finally, these control instructions are sent to the fan, motor, etc. of the air purifier to guide it to operate according to the calculated control parameters.

[0064] By generating control instructions, the air purifier can methodically execute the calculated purification power, boost time and duration, and carry out a scientific and reasonable air purification process, so as to efficiently purify the air quality and achieve the purification goals required by the user.

[0065] The following is a specific implementation method. The air purifier has a built-in particle sensor that can monitor the indoor PM2.5 concentration in real time. The user sets the air purifier to "power saving mode" through the mobile phone App. During operation, the air purifier detects that the indoor PM2.5 concentration rises sharply from 100μg / m3 to 300μg / m3 within 10 minutes. After detecting that the particle concentration exceeds the preset threshold, the parameters are calculated. According to the current concentration of 300μg / m3, the air purifier is in power saving mode, and the preset model is brought in to calculate the minimum purification power of 80W for purification, which is determined as the first purification power. The current purification power is 50W. According to the power rise and fall rate of 10W / min, the air purifier calculates that it takes (80-50) / 10=3min to smoothly increase the current power to 80W, and determines the first duration to be 3 minutes. The target purification concentration set by the user is 100μg / m3, and the concentration to be reduced is calculated to be 300-100=200μg / m3. At 80W power, the concentration decreases at a rate of 50μg / m3 / min, so the second duration is determined to be 200 / 50=4min. Based on the calculated 80W power, 3min rise time, and 4min duration, a control instruction is generated to instruct the air purifier to increase the power to 80W within 3min and continue to operate at this power for 4min. Through the control instruction, the air purifier can effectively purify the indoor air and reduce the concentration of particulate matter until the purification target is reached.

[0066] After generating the control instruction according to the first purification power, the first duration and the second duration, it also includes: if it is detected that the operating time of the air purifier exceeds the set time, an alarm message is sent to the user terminal to enable the user to adjust the air purifier.

[0067] In one example, after the air purifier generates a control instruction and runs for a period of time, it is necessary to detect whether its continuous operation time exceeds the set safety time. The reason for doing this is that long-term continuous operation in a high-power state will increase the burden and wear on the air purifier motor and transmission device. The specific implementation method is that when the controller of the air purifier generates a control instruction to execute the purification process, it also starts a timing monitoring program to detect the total operation time of the air purifier in real time. Once it is detected that the operating time exceeds the set safety threshold, the controller will automatically generate an alarm message and send the alarm letter to the user's mobile phone or other smart terminal through a network connection. The alarm message will remind the user that the air purifier has been running continuously for a certain period of time and needs to be cleaned or rested in time. This can remind users to pay attention to maintenance to avoid equipment overheating or aging caused by failure.

[0068] By adding timed monitoring and active alarm prompts during the operation of the air purifier, users can be reminded to properly care for and maintain the device, avoid mechanical failures caused by long-term excessive use, and extend the service life of the air purifier.

[0069] Based on the above method, the present application also discloses a control device for an air purifier, such as Figure 2 As shown, Figure 2 It is a structural schematic diagram of a control device for an air purifier provided in an embodiment of the present application.

[0070] A control device for an air purifier comprises: a detection module 1, a determination module 2 and an output module 3; wherein the detection module 1 is used to calculate a first purification power of the air purifier according to the target particle concentration if it is detected that the target particle concentration in the target area is greater than a threshold value within a preset time period; the determination module 2 is used to determine a first time period for adjusting the current purification power of the air purifier to the first purification power, and to determine a second time period for maintaining the operation of the first purification power; the output module 3 is used to generate a control instruction according to the first purification power, the first time period and the second time period, so that the air purifier reduces the target particle concentration in the target area according to the control instruction.

[0071] In one example, the detection module 1 is further used to calculate a first purification power of the air purifier in response to an operating mode of the air purifier set by the user end, in combination with the operating mode of the air purifier set by the user end and the target particle concentration.

[0072] In one example, if the operating mode of the air purifier set by the user end is a power saving mode, the detection module 1 is also used to determine the minimum purification power of the air purifier to purify the current target particle size concentration according to the target particle size concentration, and use the minimum purification power as the first purification power.

[0073] In one example, the detection module 1 is also used to obtain the maximum purification power of the air purifier if the operation mode of the air purifier set by the user end is the fast mode, and use the maximum purification power as the first purification power.

[0074] In one example, the determination module 2 is also used to obtain a preset power increase rate of the air purifier; and determine a first time required to increase the current purification power of the air purifier to the first purification power in combination with the preset increase rate and the first purification power.

[0075] In one example, the determination module 2 is also used to obtain the target concentration of target particles in the target area; calculate the difference between the target concentration of target particles in the target area and the target particle concentration in the current target area to obtain the concentration to be reduced; calculate the first concentration at which the target particle concentration in the target area decreases when the current purification power of the air purifier is increased to the first purification power; calculate the second concentration at which the target particle concentration in the target area decreases when the air purifier is reduced from the first purification power to the current purification power; obtain a third concentration by combining the concentration to be reduced, the first concentration and the second concentration; and determine the second time length for maintaining the first purification power based on the third concentration.

[0076] In one example, the above-mentioned device also includes sending an alarm message to the user terminal if it is detected that the operating time of the air purifier exceeds the set time, so that the user can adjust the air purifier.
