[0002] Evaporative humidifiers primarily work by spraying water onto a filter submerged in water, then using airflow generated by a fan to accelerate water evaporation. However, after humidification is complete, the filter remains damp, making it a breeding ground for microorganisms such as bacteria and mold.

[0003] Therefore, it is necessary to dry the filter after the humidifier stops humidifying. Based on this, how to achieve humidifier drying control has become an urgent problem to be solved. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In one exemplary embodiment, such as Figure 1 As shown, a method for controlling the drying of a humidifier is provided, and the method is described in the context of its application to a humidifier, including steps 101 to 103. Wherein:

[0032] Step 101: Obtain the evaporation rate of the humidifier.

[0033] In one possible implementation, the humidifier has an evaporation rate adjustment control, through which the user can input the evaporation rate, and the humidifier can obtain the evaporation rate by receiving the evaporation rate input by the user.

[0034] In another possible implementation, the humidifier's processor can determine the evaporation rate of the humidifier based on environmental parameters and / or drying parameters.

[0035] In one example, the evaporation rate of a humidifier is determined based on environmental parameters. These environmental parameters can be input into a pre-trained machine learning model to obtain the evaporation rate output by the model. During the training of the machine learning model, a computer can input a large number of various sample environmental parameters into the model, using the sample evaporation rate as a label, to perform supervised training, resulting in a well-trained machine learning model.

[0036] The environmental parameters can include ambient temperature and ambient humidity, which can be obtained through temperature and humidity sensors. These sensors can be built into the humidifier, for example, embedded in the humidifier housing, or they can be placed externally in other areas of the room besides the humidifier, for example, integrated into the intelligent humidity controller that controls the humidifier.

[0037] In another example, the evaporation rate of the humidifier is determined based on drying parameters. These drying parameters can be input into a pre-trained machine learning model to obtain the evaporation rate output by the model. During the training of the machine learning model, a computer can input a large number of various sample drying parameters into the model to be trained, using the sample evaporation rates as labels, to perform supervised training, resulting in a trained machine learning model.

[0038] The drying parameters can include the fan parameters of the humidifier, which may include at least one of the following: fan speed, fan airflow, and fan operating mode (which is also the humidifier's operating mode). The fan speed and airflow are related to the operating mode, and can be obtained from a table based on the operating mode.

[0039] In yet another example, the evaporation rate of the humidifier is determined based on environmental and drying parameters. This can be achieved through a machine learning model or a mathematical formula.

[0040] To achieve this through a machine learning model, environmental parameters and drying parameters can be input into a pre-trained machine learning model to obtain the evaporation rate of the humidifier output by the machine learning model. In the training process of the machine learning model, a computer device can input a large number of sample environmental parameters and sample drying parameters into the machine learning model to be trained, and use the sample evaporation rate as a label to perform supervised training on the machine learning model to be trained, so as to obtain a trained machine learning model.

[0041] To achieve this through mathematical formulas, one can substitute the dew point temperature, environmental parameters, and drying parameters into the mathematical formulas to calculate the evaporation rate of the humidifier.

[0042] In scenarios where the remaining drying time of the humidifier is periodically updated, the evaporation rate of the humidifier can also be obtained periodically, that is, the evaporation rate of the humidifier at the current calculation time is obtained every first preset time interval. In one possible implementation, the evaporation rate input by the user is received every first preset time interval to obtain the evaporation rate of the humidifier at the current calculation time. In another possible implementation, the evaporation rate of the humidifier at the current calculation time is determined every first preset time interval based on the environmental parameters and / or the drying parameters at the current calculation time.

[0043] Obtaining the evaporation rate of the humidifier at the current calculation time every first preset time interval refers to executing the step of obtaining the evaporation rate of the humidifier at the current calculation time once after the specified interval (i.e., the first preset time interval) has elapsed. It can be understood that each interval can be dynamically changed, for example, the current interval is 5 minutes, the next interval is 10 minutes, and the interval after that is 7 minutes, etc.; or each interval can be fixed, for example, the current interval is 5 minutes, and the next interval is also 5 minutes.

[0044] The evaporation rate of a humidifier can be obtained when the humidifier is in drying mode. Drying mode refers to a mode where the fan continues to operate to dry the filter after the humidifier stops humidifying. There are several situations in which a humidifier enters drying mode. In one possible implementation, it enters drying mode when the water level in the water tank of the humidifier is detected to be less than or equal to a preset water level value. In another possible implementation, it initiates a water filling process when the water level in the water tank of the humidifier is detected to be less than or equal to a preset water level value; if the water filling process fails, it enters drying mode. In yet another possible implementation, the humidifier enters drying mode after a trigger operation for running drying mode is detected.

[0045] Taking a scenario where the remaining drying time of a humidifier is periodically updated as an example, assuming the first preset time is T seconds, then every T seconds from the start of entering the drying mode, a step is executed to obtain the evaporation rate of the humidifier at the current calculation time. Of course, a step to obtain the evaporation rate of the humidifier at the current calculation time is also executed at the start of entering the drying mode.

[0046] Step 102: Determine the remaining drying time of the humidifier based on the initial water volume and evaporation rate in the humidifier.

[0047] Specifically, for humidifiers where the filter is immersed in a water tank, the first water volume in the humidifier can refer to the water content of the water tank and the filter in the humidifier; for humidifiers with a suspended filter, i.e., humidifiers where the filter is not immersed in a water tank, the first water volume in the humidifier can refer to the water content of the filter in the humidifier.

[0048] Regarding the initial water volume as the moisture content of the water tank and filter, it can be defined as the amount of water in the tank when the humidifier switches from a water-filled state to a waterless state; alternatively, it can be defined as the humidifier's maximum water volume, where the maximum water volume refers to the amount of water in the tank after the humidifier replenishes water when switching from a water-filled state to a waterless state. Regarding the initial water volume as the moisture content of the filter, it can be defined as the amount of water sprayed onto the filter each time the humidifier operates.

[0049] In scenarios where the remaining drying time of a humidifier is periodically updated, the first water volume can also be the remaining water volume of the humidifier at the previous moment.

[0050] The remaining drying time of a humidifier can refer to the remaining time that the humidifier will spend in the drying process.

[0051] In one possible implementation, the remaining water volume in the humidifier is determined based on the initial water volume in the humidifier and the evaporation rate; the remaining drying time of the humidifier is then determined based on the remaining water volume.

[0052] In a scenario where the remaining drying time of a humidifier is periodically updated, the remaining water volume of the humidifier at the current calculation time is determined based on the remaining water volume and evaporation rate at the previous calculation time, and the remaining drying time of the humidifier at the current calculation time is determined based on the remaining water volume and evaporation rate at the current calculation time.

[0053] Here, "previous calculation time" refers to a historical time intervald from the current calculation time by a first preset time period, and "next time" refers to a future time intervald from the current calculation time by a first preset time period. It can be understood that for a humidifier with a filter immersed in a water tank, the remaining water volume refers to the amount of water remaining in the humidifier after the water tank and filter have dried for a period of time; for a humidifier with a suspended filter, the remaining water volume refers to the amount of water remaining in the humidifier after the filter has dried for a period of time.

[0054] Step 103: Stop drying based on the remaining drying time.

[0055] Stopping drying can mean that components such as the fan in the humidifier stop drying the filter.

[0056] In one possible implementation, drying continues when the humidifier's drying time is less than the remaining drying time, and drying stops when the humidifier's drying time is greater than or equal to the remaining drying time. Here, the humidifier's drying time refers to the time elapsed from the moment the humidifier begins drying after obtaining the remaining drying time to the current moment.

[0057] In a scenario where the remaining drying time of the humidifier is periodically updated, after obtaining the remaining drying time each time, it is determined whether the drying stop condition is met. If yes, drying is stopped; otherwise, the step of obtaining the evaporation rate of the humidifier at the current calculation time is re-executed until the drying stop condition is met. The drying stop condition includes that the drying time of the humidifier from the current calculation time reaches the remaining drying time at the current calculation time before the next calculation time is reached.

[0058] In other words, after each calculation of the remaining drying time, the required drying time is redefined as the remaining drying time corresponding to the current calculation moment. If, before the next calculation moment arrives, the humidifier has already dried for the duration corresponding to the current calculation moment, the drying deadline has arrived, and drying is stopped. If, before the next calculation moment arrives, the humidifier has not dried for the duration corresponding to the current calculation moment, the process of obtaining the evaporation rate of the humidifier at the current calculation moment and determining the remaining water volume of the humidifier at the current calculation moment based on the remaining water volume and evaporation rate of the previous calculation moment is repeated, the process of determining the remaining drying time of the humidifier at the current calculation moment is repeated until the requirement is met that the humidifier has dried for the duration corresponding to the current calculation moment before the next calculation moment arrives.

[0059] For example, if the remaining drying time corresponding to the current calculation time is calculated to be 1 minute and the first preset time is 2 minutes, the humidifier will stop drying when the drying time from the current calculation time reaches 1 minute.

[0060] The above-mentioned method for controlling the drying of a humidifier obtains the evaporation rate of the humidifier, determines the remaining drying time of the humidifier based on the initial water volume and evaporation rate, and then stops drying based on the remaining drying time, thus achieving the drying control of the humidifier.

[0061] In addition, by determining the evaporation rate of the humidifier based on environmental parameters and / or drying parameters, and then determining the remaining drying time, the drying time can be automatically adjusted in real time according to environmental changes and / or drying parameters. This can achieve a more precise drying control effect. Compared with drying with a fixed drying time, it avoids situations such as energy waste due to excessive drying time or incomplete drying of the filter due to insufficient drying time, thus improving the flexibility of humidifier drying control.

[0062] In one embodiment, the remaining drying time of the humidifier is determined based on a first water volume in the humidifier and the evaporation rate, including steps 1021 and 1022, wherein...

[0063] Step 1021: Determine the remaining water volume in the humidifier based on the initial water volume and evaporation rate in the humidifier.

[0064] In one possible implementation, the evaporation rate is multiplied by the drying time to obtain the amount of water evaporated, and the difference between the initial amount of water and the amount of water evaporated is taken as the remaining amount of water. This can be expressed mathematically as follows:

[0065]

[0066] in, Indicates the remaining water volume; Indicates the first volume of water; Indicates the evaporation rate; Indicates the drying time; This indicates the amount of water that has evaporated.

[0067] Step 1022: Determine the remaining drying time of the humidifier based on the remaining water volume.

[0068] In one possible implementation, the remaining drying time is determined based on a preset target remaining water volume, the evaporation rate, and the remaining water volume. In one example, the remaining drying time is obtained by dividing the difference between the remaining water volume and the preset target remaining water volume by the evaporation rate. This can be expressed mathematically as follows:

[0069]

[0070] in, Indicates the remaining drying time; Indicates the preset target remaining water volume; This indicates the evaporation rate. The preset target remaining water volume can be set to 0 grams, thereby calculating a slightly higher remaining drying time to ensure that the filter screen reaches the target dryness range at the end of the drying process.

[0071] In a scenario where the remaining drying time of a humidifier is periodically updated, the remaining water volume at the current calculation time is determined based on the remaining water volume and evaporation rate at the previous calculation time. This includes: multiplying the evaporation rate at the previous calculation time by a first preset time to obtain the amount of water evaporated at the current calculation time; and subtracting the remaining water volume at the previous calculation time from the amount of water evaporated at the current calculation time to obtain the remaining water volume at the current calculation time. This can be expressed mathematically as follows:

[0072]

[0073] in, This indicates the remaining water volume at the current calculation time. This indicates the remaining water volume at the previous calculation time. This represents the evaporation rate at the previous calculation time. Indicates the first preset duration; This indicates the amount of water that has evaporated at the current calculation time.

[0074] In scenarios where the remaining drying time of a humidifier is periodically updated, the remaining drying time at the current calculation moment is determined based on the remaining water volume and evaporation rate at the current calculation moment. This includes determining the remaining drying time based on a preset target remaining water volume, the evaporation rate at the current calculation moment, and the remaining water volume at the current calculation moment. In one example, the difference between the remaining water volume at the current calculation moment and the preset target remaining water volume is divided by the evaporation rate at the current calculation moment to obtain the remaining drying time. This can be expressed mathematically as follows:

[0075]

[0076] in, This indicates the remaining drying time at the current calculation moment; Indicates the preset target remaining water volume; This indicates the evaporation rate at the current calculation moment. The preset target remaining water volume can be set to 0 grams, thus calculating a slightly higher remaining drying time to ensure that the filter screen reaches the target dryness range by the end of the drying process.

[0077] In this embodiment, the remaining water volume in the humidifier is determined based on the first water volume and the evaporation rate, and then the remaining drying time of the humidifier is determined based on the remaining water volume. This makes the remaining drying time determined based on the remaining water volume in the humidifier more accurate.

[0078] In one embodiment, stopping drying when the drying time of the humidifier is greater than or equal to the remaining drying time includes: stopping drying when the second water volume in the humidifier is less than or equal to the remaining water volume threshold, provided that the drying time of the humidifier is greater than or equal to the remaining drying time.

[0079] For humidifiers where the filter is immersed in a water tank, the second water volume refers to the moisture content of the water tank and filter in the humidifier housing, as detected by the humidifier, when the humidifier's drying time is greater than or equal to the remaining drying time. For humidifiers with a suspended filter, the second water volume refers to the moisture content of the filter in the humidifier housing, as detected by the humidifier, when the humidifier's drying time is greater than or equal to the remaining drying time.

[0080] For humidifiers where the filter is immersed in a water tank, the second water volume can be determined by the capacitance signal from a capacitor sensing plate located on the water tank, indicating whether it is less than or equal to the remaining water volume threshold. In one example, the capacitor signal from the capacitor sensing plate is received. When the capacitance value corresponding to the signal is less than a preset capacitance value, it indicates that the second water volume is less than or equal to the remaining water volume threshold; when the capacitance value is greater than the preset capacitance value, it indicates that the second water volume is greater than the remaining water volume threshold. The preset capacitance value is the capacitance value corresponding to the capacitance signal sent by the capacitor sensing plate in a dry state.

[0081] For humidifiers with suspended filters, the second water volume can be determined by the capacitance signal from a capacitor sensing plate mounted on the filter screen, indicating whether it is less than or equal to the remaining water volume threshold. In one example, the capacitor signal from the capacitor sensing plate on the filter screen is received. When the capacitance value corresponding to the signal is less than a preset capacitance value, it indicates that the second water volume is less than or equal to the remaining water volume threshold; when the capacitance value is greater than the preset capacitance value, it indicates that the second water volume is greater than the remaining water volume threshold. The preset capacitance value is the capacitance value corresponding to the capacitance signal sent by the capacitor sensing plate in a dry state.

[0082] If the second water volume in the humidifier is greater than the remaining water volume threshold, the step of obtaining the evaporation rate of the humidifier is repeated until the second water volume in the humidifier is less than or equal to the remaining water volume threshold.

[0083] It should be noted that re-executing the step of obtaining the evaporation rate of the humidifier, that is, re-executing step 101, does not mean that only step 101 is executed, but rather that step 101 and other steps after step 101 are executed, and the same applies below.

[0084] In a scenario where the remaining drying time of the humidifier is periodically updated, after each time the remaining drying time is obtained, it is determined whether the drying stop condition is met. If so, drying is stopped. This includes: after each time the remaining drying time is obtained, if the drying time of the humidifier from the current calculation time reaches the remaining drying time corresponding to the current calculation time before the next time arrives, and the second water volume in the humidifier is less than or equal to the remaining water volume threshold, then drying is stopped.

[0085] If, before the next moment arrives, the drying time of the humidifier from the current calculation moment reaches the remaining drying time corresponding to the current calculation moment, and the second water volume in the humidifier is greater than the remaining water volume threshold, then the step of obtaining the evaporation rate of the humidifier at the current calculation moment is executed again until the second water volume in the humidifier is less than or equal to the remaining water volume threshold.

[0086] In other words, the conditions for stopping drying include that, before the next calculation time, the drying time of the humidifier from the current calculation time reaches the remaining drying time of the current calculation time, and the second water volume in the humidifier is less than or equal to the remaining water volume threshold.

[0087] In this embodiment, by stopping drying when the second water volume in the humidifier is less than or equal to the remaining water volume threshold, it is further ensured that the filter in the humidifier is in a dry state before drying is stopped.

[0088] In one embodiment, the environmental parameters include ambient temperature and ambient humidity; determining the evaporation rate of the humidifier based on the environmental parameters and / or drying parameters includes: determining the dew point temperature based on the ambient temperature and ambient humidity; and determining the evaporation rate based on the dew point temperature, environmental parameters, and drying parameters.

[0089] Dew point temperature represents the temperature at which water vapor in the air reaches saturation. It is related to both ambient temperature and humidity, and can be obtained by referring to a table. The relationship between dew point temperature, ambient temperature, and ambient humidity is shown in Table 1. In Table 1, both dew point temperature and ambient temperature are in degrees Celsius, and ambient humidity is expressed as a percentage of relative humidity.

[0090] Table 1

[0091]

[0092] Drying parameters include airflow. The evaporation rate is determined based on dew point temperature, environmental parameters, and drying parameters, including: determining the evaporation rate based on dew point temperature, ambient temperature, ambient humidity, and airflow. Specifically, the formula for calculating the evaporation rate is as follows:

[0093]

[0094] in, This indicates the evaporation rate, expressed in g / min. This indicates air volume, measured in m³ / h. Indicates ambient humidity; Indicates ambient temperature; This indicates the dew point temperature.

[0095] In a scenario where the remaining drying time of the humidifier is periodically updated, the environmental parameters at the current calculation time include the ambient temperature and humidity at the current calculation time. Based on the environmental parameters and / or the drying parameters at the current calculation time, the evaporation rate in the humidifier at the current calculation time is determined, including: determining the dew point temperature at the current calculation time based on the ambient temperature and humidity at the current calculation time; and determining the evaporation rate at the current calculation time based on the dew point temperature, the environmental parameters, and the drying parameters at the current calculation time.

[0096] The evaporation rate at the current calculation time is determined based on the dew point temperature, environmental parameters, and drying parameters at the current calculation time. This includes determining the evaporation rate based on the dew point temperature, ambient temperature, ambient humidity, and airflow at the current calculation time. Specifically, the formula for calculating the evaporation rate at the current calculation time is as follows:

[0097]

[0098] in, This represents the evaporation rate at the current calculation time, in g / min. This indicates the air volume at the current calculation moment, in m³ / h. Indicates the ambient humidity at the current calculation time; This indicates the ambient temperature at the current calculation time. This represents the dew point temperature at the current calculation moment.

[0099] In this embodiment, the evaporation rate is calculated taking into account the dew point temperature, so the calculated evaporation rate is closer to the actual situation. Therefore, the evaporation rate calculated based on the dew point temperature is more accurate.

[0100] In one embodiment, determining the evaporation rate based on dew point temperature, environmental parameters, and drying parameters includes determining the evaporation rate of the humidifier based on the evaporation coefficient, dew point temperature, environmental parameters, and drying parameters.

[0101] The evaporation coefficient is obtained in advance through testing based on the humidifier's attribute information, including its structural characteristics and the operating environment. The structural characteristics include the surface area of ​​the filter, its pore size, material, and moisture content. The operating environment refers to factors such as air circulation, air pressure, and pollutant levels in the room where the humidifier is located. Both these structural characteristics and the operating environment affect the evaporation rate; therefore, it is necessary to test and determine the corresponding evaporation coefficient in advance to ensure compatibility with the appropriate humidifier.

[0102] The formula for calculating the evaporation rate is as follows:

[0103]

[0104] in, This represents the evaporation coefficient. The other parameters in this formula have been explained in detail above and will not be repeated here.

[0105] In scenarios where the remaining drying time of a humidifier is periodically updated, the evaporation rate at the current calculation time is determined based on the dew point temperature, environmental parameters, and drying parameters at the current calculation time. This includes determining the evaporation rate at the current calculation time based on the evaporation coefficient, the dew point temperature, environmental parameters, and drying parameters at the current calculation time.

[0106] The formula for calculating the evaporation rate at the current calculation moment is as follows:

[0107]

[0108] in, This represents the evaporation coefficient. The other parameters in this formula have been explained in detail above and will not be repeated here.

[0109] The following is the inventor's test process for the evaporation coefficient. It can be seen that the evaporation coefficient is an important parameter in calculating the evaporation rate.

[0110] The test conditions were as follows: ambient temperature: 21℃±1℃; ambient humidity: 30%±5%, where 5% is the measurement error of humidity; dew point temperature: approximately 2.76℃±0.86℃, which was obtained from a humidity calculation tool.

[0111] Test equipment settings: The corresponding relationship between the fan's operating speed and air volume: 3rd speed: 2500 RPM, air volume 80.1 m³ / h; 2nd speed: 2150 RPM, air volume 68.8 m³ / h; 1st speed: 1100 RPM, air volume 35.3 m³ / h.

[0112] Test process: The drying time was set to 45 minutes, 60 minutes and 120 minutes respectively, and the weight of the filter screen of each test device after different drying times was recorded.

[0113] The test data is shown in Table 2.

[0114] Table 2

[0115]

[0116] The formula for calculating the evaporation coefficient k is as follows:

[0117]

[0118] in, This indicates the weight of the filter screen before drying during the test process; This indicates the drying time during the test; This indicates the airflow during the test, which is related to the operating speed during the test. Indicates the ambient humidity during the testing process; Indicates the ambient temperature during the test; This indicates the dew point temperature during the test.

[0119] Table 2 shows that the average evaporation coefficient at different speed settings is 0.00136 (speed 3), 0.00134 (speed 2), and 0.00131 (speed 1); the maximum evaporation coefficient at different speed settings is 0.00142 (speed 3), 0.00137 (speed 2), and 0.00134 (speed 1); and the minimum evaporation coefficient at different speed settings is 0.00122 (speed 3), 0.00133 (speed 2), and 0.00128 (speed 1). The test data shows that the evaporation coefficient remains relatively stable under different testing equipment and different wind speed settings, indicating that the formula for calculating the evaporation rate in this application is effective.

[0120] In this embodiment, the evaporation rate is calculated by taking into account the evaporation coefficient related to the humidifier's properties. This makes the calculated evaporation rate closer to the actual situation, and therefore, the evaporation rate calculated based on the evaporation coefficient is more accurate.

[0121] In one embodiment, the method further includes: when a trigger operation for adjusting the operating level is detected, re-executing the step of obtaining the evaporation rate of the humidifier.

[0122] In other words, if the user adjusts the operating level, the humidifier will readjust the remaining drying time based on the newly adjusted operating level.

[0123] In a scenario where the remaining drying time of the humidifier is periodically updated, the method further includes: after obtaining the remaining drying time each time, if a trigger operation for adjusting the working level is detected before the next moment arrives, the step of obtaining the evaporation rate of the humidifier at the current calculation moment is re-executed.

[0124] In this embodiment, the flexibility of humidifier drying control is further improved by re-executing the step of obtaining the evaporation rate of the humidifier when a trigger operation for adjusting the working level is detected.

[0125] In one embodiment, the method further includes adjusting the operating setting based on the remaining drying time.

[0126] In one possible implementation, the operating speed is adjusted when the remaining drying time exceeds the second preset time.

[0127] In other words, after calculating the remaining drying time, it is also necessary to determine whether the calculated remaining drying time is too long. If it is too long, it may be due to the current working level being too low. Considering that components such as fans will work for a long time, resulting in high power consumption and affecting user experience, the working level can be automatically increased to speed up drying.

[0128] In scenarios where the remaining drying time of the humidifier is periodically updated, the method further includes:

[0129] After obtaining the remaining drying time each time, if the remaining drying time at the current calculation time exceeds the second preset time, the working speed will be adjusted.

[0130] In other words, after obtaining the remaining drying time each time, it is also necessary to determine whether the remaining drying time calculated this time is too long. If it is too long, it may be due to the current working level being too low. Considering that components such as fans will work for a long time, resulting in high power consumption and affecting user experience, the working level can be automatically increased to dry faster.

[0131] In another possible implementation, the operating setting is adjusted when the remaining drying time exceeds a third preset time. The third preset time is greater than the second preset time.

[0132] In other words, after calculating the remaining drying time, it is also necessary to determine whether the calculated remaining drying time is too short. If it is too short, it may be due to the current working speed being too high. Considering that the long-term high-speed rotation of components such as fans will affect their service life, the working speed can be automatically lowered.

[0133] In a scenario where the remaining drying time of the humidifier is periodically updated, the method further includes: after each time the remaining drying time is obtained, if the remaining drying time corresponding to the current calculation time is greater than a third preset time, then adjusting the operating level. The third preset time is greater than a second preset time.

[0134] In other words, after obtaining the remaining drying time each time, it is also necessary to determine whether the remaining drying time calculated this time is too short. If it is too short, it may be due to the current working speed being too high. Considering that the long-term high-speed rotation of components such as fans will affect their service life, the working speed can be automatically adjusted to a lower level.

[0135] In one embodiment, the evaporation rate of the humidifier is obtained; the remaining drying time of the humidifier is determined based on a first water volume in the humidifier and the evaporation rate; and drying is stopped based on the remaining drying time, including:

[0136] The evaporation rate of the humidifier at the current calculation time is obtained every first preset time interval; and the remaining water volume of the humidifier at the current calculation time is determined based on the remaining water volume and evaporation rate of the humidifier at the previous calculation time; and the remaining drying time of the humidifier at the current calculation time is determined based on the remaining water volume and evaporation rate of the current calculation time.

[0137] Determine whether the drying stop condition is met. If yes, stop drying. If not, repeat the step of obtaining the evaporation rate of the humidifier at the current calculation time until the drying stop condition is met. The drying stop condition includes that the drying time of the humidifier from the current calculation time reaches the remaining drying time at the current calculation time before the next calculation time is reached.

[0138] The implementation method of this embodiment can refer to the above embodiment, and will not be repeated here. In this embodiment, the remaining drying time is updated every first preset time interval, thereby realizing real-time automatic adjustment of the drying time according to environmental changes, further improving the flexibility of humidifier drying control.

[0139] In one example, such as Figure 2 The diagram shows the architecture of a humidifier, which includes a temperature and humidity sensor, a computing unit, a timer, and a fan. The temperature and humidity sensor can send the detected ambient temperature and humidity to the computing unit. The fan can feed back drying parameters, such as airflow or wind speed, to the computing unit.

[0140] Based on environmental and drying parameters, the evaporation rate of the humidifier is determined. Then, based on the initial water volume in the humidifier and the evaporation rate, the remaining water volume in the humidifier is determined. Based on the remaining water volume, the remaining drying time of the humidifier is determined. The calculation unit then sends the remaining drying time to a timer. The timer counts down based on the received remaining drying time and sends feedback on the drying progress to the calculation unit, allowing the calculation unit to know how long the fan has been running and thus determine whether to turn it off.

[0141] In a scenario where the remaining drying time of a humidifier is periodically updated, the calculation unit determines the evaporation rate of water in the humidifier at the current calculation time based on the environmental parameters and drying parameters at the current calculation time every first preset time interval. Then, based on the remaining water volume and evaporation rate of the humidifier at the previous calculation time, it determines the remaining water volume of the humidifier at the current calculation time; and based on the remaining water volume at the current calculation time, it determines the remaining drying time of the humidifier at the current calculation time. The calculation unit then sends the remaining drying time at the current calculation time to a timer. The timer counts down in real time based on the received remaining drying time at the current calculation time and feeds back the drying progress to the calculation unit so that the calculation unit can know how long the fan has been working and thus determine whether to turn off the fan.

[0142] In one example, such as Figure 3 The diagram shows a flowchart of another humidifier drying control method, with the specific steps as follows:

[0143] The water level in the tank carrying the submerged filter screen is detected by a capacitive water detection plate. The water level in the tank carrying the submerged filter screen is as follows: Figure 4 As shown.

[0144] When the water level is detected to be less than or equal to the preset water level value, such as less than or equal to 3mm, the capacitive water detection board outputs a water tank no-water signal to the main control MCU (Microcontroller Unit).

[0145] After receiving a signal that the water tank is empty, the main control MCU starts the water filling process, which means controlling the solenoid valve to open so that water is added from the water tank to the water tank to maintain the required water level and ensure that the humidifier continues to work.

[0146] When the detected water level is higher than the preset water level value, the humidifier continues to operate and humidify.

[0147] If the water filling process is successful after starting, and the water level reaches the target level, the humidifier will continue to operate and humidify.

[0148] If the water filling process fails after starting, the humidifier will switch to drying mode.

[0149] After entering drying mode, the humidifier determines its evaporation rate based on environmental and drying parameters; it then determines the remaining water level based on the initial water volume and evaporation rate; and finally, it determines the remaining drying time based on the remaining water volume. When the humidifier's drying time is greater than or equal to the remaining drying time, it checks whether the second water volume in the humidifier is less than or equal to the remaining water volume threshold. If so, the humidifier's fan is turned off, and the drying mode is exited; otherwise, the process continues to determine the evaporation rate based on environmental and drying parameters.

[0150] In a scenario where the remaining drying time of a humidifier is periodically updated, after entering drying mode, the humidifier determines its evaporation rate at the current calculation time based on the environmental parameters and drying parameters at the current calculation time every first preset time interval. It then determines the remaining water volume in the humidifier at the current calculation time based on the remaining water volume and evaporation rate at the previous calculation time. Finally, it determines the remaining drying time corresponding to the current calculation time based on the remaining water volume. After each time the remaining drying time is obtained, if the drying time from the current calculation time reaches the remaining drying time corresponding to the current calculation time before the next time interval arrives, it checks whether the second water volume in the humidifier is less than or equal to the remaining water volume threshold. If so, the humidifier fan is turned off, and the drying mode is exited; otherwise, the step of determining the evaporation rate based on the environmental parameters and drying parameters at the current calculation time continues. After obtaining the remaining drying time each time, if the drying time of the humidifier from the current calculation time has not reached the remaining drying time corresponding to the current calculation time before the next time arrives, then continue to execute the step of determining the evaporation rate of the humidifier at the current calculation time based on the environmental parameters and drying parameters at the current calculation time.

[0151] In summary, the humidifier drying control method of this application has the following advantages:

[0152] Precise environmental data analysis: By detecting and analyzing the temperature and humidity in the user's environment in real time, it provides more accurate data support for the operation of the humidifier, ensuring the stability and reliability of the humidification effect.
