Abstract
Description
Technical Field
[0001] This invention relates to the field of humidifier control technology, and in particular to a humidity regulating device and a humidifier drainage control method and apparatus. Background Technology
[0002] Currently, constant temperature and humidity air conditioning is widely used in various industries. Achieving constant temperature and humidity control requires the use of humidifiers to compensate for humidity levels. Electrode humidifiers have low requirements for inlet water quality and are safe and reliable in operation, leading to their widespread application in the field of constant temperature and humidity air conditioning. However, electrode humidifiers require water quality management through regular full drainage to extend their lifespan and reduce scaling.
[0003] A full drain cycle refers to draining all the water from the humidifier by opening a drain valve or pump for a period of time, then refilling with water and re-managing the water quality. During a full drain cycle, the humidifier outputs no steam. If full drain cycles are performed frequently and for too long, the conductivity of the water inside the humidifier will gradually increase, posing a risk of a sudden surge in current. This will cause the humidifier's control (current control) accuracy to deviate from normal values.
[0004] Existing humidifiers employ two main types of full-drainage methods: the first is timed drainage, which drains water at fixed intervals or frequencies; the second is periodic predictive drainage based on the conductivity of the influent water—increasing the drainage cycle when the conductivity is low and shortening it when it is high. Both existing full-drainage methods suffer from poor intelligence, waste of water and electricity, and energy inefficiency, impacting control accuracy and effectiveness. Summary of the Invention

[0055] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0057] Figure 1 This is a flowchart of a first humidifier drainage control method according to an embodiment of the present invention. This embodiment is applicable to application scenarios in which a humidifier is controlled to perform a full drainage action using a non-fixed periodic drainage method.
[0058] like Figure 1 As shown, the method includes:
[0059] S10, Obtain the first inlet water conductivity and the first humidification signal of the humidifier.
[0060] The first inlet water conductivity can be a parameter characterizing the ease of charge flow within the humidifier. Higher conductivity in the water increases the risk of excessive instantaneous current, affecting the humidifier's normal operation. The first humidification signal can be a humidification output signal; one humidification signal corresponds to one humidification value. Humidification values corresponding to the same humidification signal fall within the same threshold range, such as 30% ± 5% or 50% ± 5%. It's understood that the first inlet water conductivity and the first humidification signal can be specific values or corresponding ranges. Upon receiving the humidification signal, the inlet valve opens, allowing water to enter the humidifier.
[0061] S11. Import the first inlet water conductivity and the first humidification signal into the preset model to determine the first inlet water cycle and the target running time.
[0062] Among them, the water inlet cycle represents the time interval between the action times of the water inlet valve corresponding to two adjacent identical humidification signals; the target running time represents the continuous running time of the humidifier.
[0063] The preset models include: a first preset model for characterizing the correspondence between the first influent conductivity and the first humidification signal and the first influent cycle; and a second preset model for characterizing the correspondence between the first influent conductivity and the target running time.
[0064] The first water inlet cycle can be the interval between two consecutive water inlets of the humidifier under the first humidification signal and the first conductivity. For example, when the first humidification signal is 50%-60% and the first water inlet conductivity is 300-600 μS / cm, the first water inlet cycle can be 20 seconds. When the first humidification signal is the same but the water inlet conductivity is different, the different water inlet conductivity will lead to different water inlet times, thus resulting in different first water inlet cycles. In this embodiment, a first preset model can be established based on calibration data between the first water inlet conductivity, the first humidification signal, and the first water inlet cycle. The first water inlet conductivity and the first humidification signal are then input into the first preset model to obtain the first water inlet cycle.
[0065] The target running time is obtained because the conductivity of the water inside the humidifier increases with longer water circulation time. Therefore, to ensure the accuracy and effectiveness of the humidifier, it is necessary to periodically drain the water to maintain the conductivity inside the humidifier. In this embodiment, a second preset model can be established based on calibration data between the target running time and the first inlet water conductivity. By detecting the first inlet water conductivity and inputting it into this preset model, the target running time conductivity can be obtained.
[0066] S12. After the humidifier has been running for the target time, acquire at least two second humidification signals.
[0067] The humidification amount of the second signal is the same as or within the same preset humidification amount range as the humidification amount of the first humidification signal. Typically, the preset humidification amount range can be a humidification amount range in which the humidification amount of the first humidification signal fluctuates by no more than 5%. Acquiring at least two second humidification signals can be used to determine the second water inlet cycle.
[0068] S13. Determine the second water inlet cycle based on the time interval between at least two second humidification signals.
[0069] The second water inlet cycle can be defined as the interval between two consecutive water inlets at the second humidification signal and the first conductivity level, following the humidifier's target operating time. In practical applications, as steam evaporates from the humidifier, the concentration of conductive elements inside the humidifier gradually increases, leading to higher conductivity and a faster rate of current change. Therefore, the second water inlet cycle will be shorter than the first. It is understandable that obtaining more identical second humidification signals and averaging multiple second water inlet cycles will result in a more accurate calculation of the second water inlet cycle.
[0070] S14. Determine the cycle decay rate based on the first and second water intake cycles.
[0071] In this invention, the first water inlet cycle is defined as T1, and the second water inlet cycle as T2. The cycle decay rate AF satisfies AF = T2 / T1. The cycle decay rate can be used as an indicator to measure whether a full drain is required. Existing technologies only measure a single value of the second water inlet cycle. However, the cycle of the humidifier is affected by environmental factors. This invention determines whether a full drain is required for the humidifier by comparing the changes between the first and second water inlet cycles, thus eliminating the influence of environmental factors.
[0072] S15. Determine whether to trigger full drainage based on the periodic decay rate.
[0073] The system can be configured to trigger full drainage when the cycle decay rate is less than a preset cycle decay rate. A smaller cycle decay rate indicates a shorter second water inlet cycle, higher conductivity within the humidifier, and a greater need for full drainage. The preset cycle decay rate can be obtained based on the first water inlet conductivity and the first humidification signal. Alternatively, a maximum cycle decay rate can be set. When the cycle decay rate exceeds the maximum cycle decay rate, full drainage is performed based on a preset maximum drainage time for the first water inlet conductivity.
[0074] For example, Figure 2 This is a schematic diagram of intelligent drainage cycle control for a humidifier according to an embodiment of the present invention. Figure 2 In the illustrated embodiment, the horizontal axis represents the humidifier's operating time, and the vertical axis represents the water content within the humidifier. 预设 Indicates standard moisture content.
[0075] like Figure 2 As shown, at time t1, the water content in the humidifier reaches 0.9-0.95 times the standard water content, triggering the humidification signal, opening the water inlet valve, and starting water intake in the humidifier; at time t2, the water content in the humidifier reaches 1.05-1.1 times the standard water content, stopping the humidification signal, closing the water inlet valve, and stopping water intake in the humidifier.
[0076] Combination Figure 1 and Figure 2As shown, taking the first influent conductivity of 300 - 600 μS / cm and the first humidification signal of 50% - 60% as an example, the first influent conductivity and the first humidification signal are imported into a preset model, and the first influent cycle T1 is obtained as 20S, the target operation time is 60min, and the preset cycle decay rate A0 is 0.2; after the humidifier operates for 60min, the time intervals when at least two second humidification signals are 50% - 60% are obtained, and the second influent cycle T2 is determined to be 3S; according to the first influent cycle and the second influent cycle, the cycle decay rate AF = T2 / T1 is calculated, and the cycle decay rate AF is calculated to be 0.15. By comparing the cycle decay rate with the preset cycle decay rate, AF < AO, it is determined to trigger full drainage.
[0077] The technical solution of the embodiment of the present invention obtains the first influent cycle and the second influent cycle after the humidifier has worked for a period of time, calculates the cycle decay rate, and triggers the full drainage action through the cycle decay rate, so that the drainage interval time changes with the change of the cycle decay rate. By detecting the influent cycle, the drainage cycle is adaptively adjusted, the intelligence of the drainage cycle is improved, the drainage time of the humidifier is optimized, and the control accuracy of the humidifier is increased.
[0078] In some embodiments, the preset model can be a preset influent cycle list, and the preset influent cycle list is a data table established based on the corresponding relationship between the influent conductivity, the humidification signal, and the influent cycle.
[0079] Among them, the preset influent cycle list is a data table established based on the corresponding relationship between the influent conductivity, the humidification signal, and the influent cycle. When the first influent conductivity and the first humidification signal are obtained, the first influent cycle can be obtained by querying the data table.
[0080] In some other embodiments, the preset model can be a preset self - learning model. The preset self - learning model is a data model established by using the influent conductivity and the humidification signal as input parameters and the influent cycle as an output parameter for self - learning training.
[0081] Among them, the data model is a self - learning model, and the model parameters of the self - learning model are trained by using the influent data of a large number of humidifiers. In this embodiment, multiple groups of first influent conductivity, first humidification signal, and influent cycle data are obtained through calibration or testing. The first influent conductivity and the first humidification signal are used as model input parameters, and the influent cycle is used as the model output parameter to train the self - learning model so that the self - learning model is applicable to predicting the influent cycle.
[0082] Typically, the preset self - learning model can be a neural network model.
[0083] It is understood that the preset water inlet cycle list and preset self-learning model in this invention are both implementation methods for obtaining the water inlet cycle through water conductivity and humidification signal, and can be selected according to actual application. This embodiment of the invention does not limit this.
[0084] Optionally, the target running time is negatively correlated with the conductivity of the first influent.
[0085] The target runtime is greater than or equal to 30 minutes and less than or equal to 90 minutes.
[0086] The target running time is negatively correlated with the conductivity of the first inlet water because the conductivity of the water inside the humidifier increases with the longer the water circulation time. The higher the conductivity of the first inlet water, the shorter the target running time; the lower the conductivity of the first inlet water, the longer the target running time. To ensure the accuracy and performance of the humidifier, the humidifier is drained regularly to maintain its internal conductivity.
[0087] The water inlet cycle of the humidifier is limited to a time interval of 30 minutes or more and 90 minutes or less. Since the water inlet cycle is related to the water outlet cycle, this is to prevent the humidifier from draining for too long during full drainage, which would affect the user experience.
[0088] Based on the above embodiments, Figure 3 This is a flowchart of a second humidifier drainage control method provided according to an embodiment of the present invention, as shown below. Figure 3 As shown, the method includes:
[0089] S20: Obtain the first inlet water conductivity and the first humidification signal of the humidifier.
[0090] S21. Import the first inlet water conductivity and the first humidification signal into the preset model to determine the first inlet water cycle and the target running time.
[0091] S22. After the humidifier has been running for the target time, acquire at least two second humidification signals.
[0092] S23. Determine a single water inlet cycle based on the time interval between two adjacent second humidification signals.
[0093] The time interval between two adjacent second humidification signals is the time interval between two adjacent second humidification signal times, which is a single water inlet cycle.
[0094] S24. Determine the second water intake cycle based on a single water intake cycle or at least two consecutive single water intake cycles.
[0095] To ensure the accuracy of the second water intake cycle, at least two consecutive water intake cycles can be obtained. The average of the multiple water intake cycles is calculated, and the average of the multiple water intake cycles is determined as the second water intake cycle.
[0096] S25. Determine the cycle decay rate based on the first and second water intake cycles.
[0097] S26. Determine whether to trigger full drainage based on the periodic decay rate.
[0098] Specifically, steps S23 to S24 above describe a specific implementation method for calculating the second water intake cycle. The second water intake cycle can be calculated using a single water intake cycle or the average value of multiple consecutive water intake cycles.
[0099] By acquiring multiple individual water inlet cycles and then acquiring the second water inlet cycle through multiple consecutive individual water inlet cycles, the accuracy of the second water inlet cycle and the control precision of the humidifier are improved.
[0100] Based on the above embodiments, Figure 4 This is a flowchart of a third humidifier drainage control method according to an embodiment of the present invention, as shown below. Figure 4 As shown, the method includes:
[0101] S30: Obtain the first inlet water conductivity and the first humidification signal of the humidifier.
[0102] S31. Import the first inlet water conductivity and the first humidification signal into the preset model to determine the first inlet water cycle and the target running time.
[0103] S32. After the humidifier has been running for the target time, acquire at least two second humidification signals.
[0104] S33. Determine the second water inlet cycle based on the time interval between at least two second humidification signals.
[0105] S34. Determine the cycle decay rate based on the first and second water intake cycles.
[0106] S35. Obtain the preset lower limit threshold of attenuation rate.
[0107] The preset attenuation rate lower limit threshold is the minimum threshold of the periodic attenuation rate. In this embodiment, the preset attenuation rate lower limit threshold can be set to any value within the range of 0.1-0.5. The preset attenuation rate lower limit threshold can be obtained based on the first inlet water conductivity and the first humidification signal. The preset attenuation rate lower limit threshold can be an attenuation rate range or a single attenuation rate value, and there is no limitation on this.
[0108] S36. Compare the periodic decay rate with the preset lower limit threshold of decay rate.
[0109] S37. If the periodic decay rate is less than or equal to the preset lower limit threshold of decay rate, then full drainage is triggered.
[0110] Specifically, steps S35 to S37 describe a specific method for determining whether to trigger full drainage based on the periodic decay rate. By comparing the periodic decay rate with a preset lower limit threshold, when the periodic decay rate is less than or equal to the preset lower limit threshold, it indicates that the conductivity of the second inlet water in the humidifier has increased to a certain value and full drainage is required. At this time, full drainage is triggered.
[0111] For example, taking a preset attenuation rate lower limit threshold of 0.1 as an example, the cycle attenuation rate is compared with the preset attenuation rate lower limit threshold of 0.1. When the cycle attenuation rate is less than or equal to 0.1, full drainage is triggered.
[0112] The technical solution of this invention obtains a preset lower limit threshold for attenuation rate. When the cycle attenuation rate is less than or equal to the preset lower limit threshold, it indicates that the conductivity of the second inlet water has reached the humidifier's drainage requirements. At this time, the full drainage function is triggered, which improves the intelligence of the drainage cycle, optimizes the drainage time of the humidifier, and improves the control accuracy of the humidifier.
[0113] Based on the above embodiments, Figure 5 This is a flowchart of the fourth humidifier drainage control method provided by an embodiment of the present invention, as shown below. Figure 5 As shown, the method includes:
[0114] S40: Obtain the first inlet water conductivity and the first humidification signal of the humidifier.
[0115] S41. Import the first inlet water conductivity and the first humidification signal into the preset model to determine the first inlet water cycle and the target running time.
[0116] S42. After the humidifier has been running for the target time, obtain the second inlet water conductivity of the humidifier.
[0117] The conductivity of the second inlet water is the same as that of the first inlet water or is within the same preset conductivity range.
[0118] S43. Determine the rate of change of inlet water conductivity based on the first inlet water conductivity and the second inlet water conductivity.
[0119] Specifically, the difference between the inlet water conductivity and the inlet water conductivity is determined based on the first inlet water conductivity and the second inlet water conductivity, and this difference is used as the rate of change of inlet water conductivity.
[0120] S44. Determine whether to start obtaining the second humidification signal based on the change rate of influent conductivity.
[0121] Specifically, steps S43 to S44 above describe a specific implementation of the triggering condition for acquiring the second humidification signal. A preset inlet water conductivity change rate (e.g., 100 μS / cm) can be set. When the inlet water conductivity change rate is greater than the preset inlet water conductivity change rate, it indicates that the inlet water conductivity fluctuates significantly. To avoid the influence of inlet water conductivity fluctuation on the humidifier's water inlet and outlet operations, the second humidification signal is not acquired at this time. When the inlet water conductivity change rate is less than or equal to the preset inlet water conductivity change rate, it indicates that the inlet water conductivity fluctuates slightly. At this time, the second humidification signal is acquired, and further detection is performed using the above scheme.
[0122] The technical solution of this invention obtains the second inlet water conductivity and determines the inlet water conductivity change rate based on the second inlet water conductivity. When the inlet water conductivity change rate is greater than the preset inlet water conductivity change rate, the acquisition of the second humidification signal is initiated, which ensures the accuracy of the humidifier's full drainage determination and optimizes the drainage time.
[0123] Figure 6 This is a flowchart of a fifth humidifier drainage control method according to an embodiment of the present invention, which adds a periodic decay rate monitoring function based on the above embodiments.
[0124] like Figure 6 As shown, the method includes:
[0125] S50: Obtain the first inlet water conductivity and the first humidification signal of the humidifier.
[0126] S51. Import the first inlet water conductivity and the first humidification signal into the preset model to determine the first inlet water cycle and the target running time.
[0127] S52. After the humidifier has been running for the target time, acquire at least two second humidification signals.
[0128] S53. Determine the second water inlet cycle based on the time interval between at least two second humidification signals.
[0129] S54. Determine the cycle decay rate based on the first and second water intake cycles.
[0130] S55. Determine whether the period decay rate is higher than the preset decay rate upper limit threshold.
[0131] The preset attenuation rate upper limit threshold is the maximum threshold of the preset attenuation rate. The preset attenuation rate can be obtained based on the first inlet water conductivity and the first humidification signal. For example, if the preset attenuation rate is obtained as 0.1-0.5, then the preset attenuation rate upper limit threshold is 0.5; the periodic attenuation rate is compared with the preset attenuation rate upper limit threshold of 0.5.
[0132] S56. If the cycle decay rate is higher than the preset decay rate upper limit threshold, then obtain the real-time water inlet conductivity of the humidifier.
[0133] When the cycle decay rate is greater than the preset upper limit threshold, it means that the cycle decay rate cannot determine whether the humidifier needs to be fully drained. At this time, the real-time water inlet conductivity of the humidifier is obtained, and the full drainage is determined by judging the water inlet conductivity.
[0134] S57. Determine the target drainage interval time based on the real-time influent conductivity.
[0135] Among them, the influent conductivity is related to the target drainage interval time.
[0136] In one embodiment, determining the target drainage interval time based on the real-time influent conductivity includes: looking up a preset drainage schedule based on the real-time influent conductivity to determine the target drainage interval time; wherein the preset drainage schedule is a data list established based on the correspondence between influent conductivity and drainage interval time.
[0137] The process involves establishing a correspondence between real-time inlet water conductivity and preset drainage time. The target drainage interval is determined based on the real-time inlet water conductivity. The preset drainage time can be adjusted according to different humidifiers or their application scenarios to improve the accuracy of the target drainage interval.
[0138] For example, when the influent conductivity is <300μS / cm, the longest target drainage interval is 60min; when the influent conductivity is in the range of 300-600μS / cm, the longest target drainage interval is 40min; when the influent conductivity is >600μS / cm, the longest target drainage interval is 40min.
[0139] S58. Trigger full drainage based on the target drainage interval.
[0140] When the humidifier reaches the target drainage interval, it indicates that the inlet water conductivity has reached the full drainage requirement, and full drainage is triggered at this time.
[0141] The technical solution of this invention, when the cycle decay rate exceeds a preset upper limit threshold, obtains the target drainage interval time through real-time inlet water conductivity. Once the humidifier reaches the target drainage interval time, full drainage is triggered. This avoids the problem of the humidifier failing to perform full drainage based on the cycle decay rate due to detection failure or error, achieving secondary monitoring and protection of the humidifier's drainage cycle and ensuring the accuracy of humidifier drainage control. When the cycle decay rate is abnormal, the drainage time is determined by looking up a table using real-time inlet water conductivity, and full drainage is initiated. The algorithm is simple and improves the reliability of the system's drainage action.
[0142] Based on the same inventive concept, this invention also provides a humidifier drainage control device for executing a humidifier drainage control method. Figure 7 This is a schematic diagram of the structure of a humidifier drainage control device according to an embodiment of the present invention, as shown below. Figure 7 As shown, the device includes:
[0143] The first detection module 100 is used to acquire the first inlet water conductivity and the first humidification signal of the humidifier.
[0144] The first calculation module 200 is used to import the first inlet water conductivity and the first humidification signal into a preset model to determine the first inlet water cycle and the target running time.
[0145] The second detection module 300 is used to acquire at least two second humidification signals after the humidifier has been running for a target time.
