[0013] The preset heating time is the time it takes for the water temperature in the water circulation system to reach a preset temperature threshold, which is determined in advance based on different water volumes and corresponding preset heating power.

[0014] Optionally, before detecting the current water volume of the humidifier, the method further includes:

[0015] Collect water temperature values ​​of different types of heating elements under different water volumes and multiple initial heating powers, and generate the water temperature value change curve with the initial heating time to obtain the initial temperature change curve;

[0017] Optionally, after reaching the preset heating time, the process further includes:

[0018] The heating element is controlled to continue heating the water in the water circulation system in order to maintain the water temperature in the water circulation system within a preset temperature range.

[0019] Optionally, maintaining the water temperature within the water circulation system within a preset temperature range includes:

[0020] The heating element is controlled by pulse heating technology and the target heating power is used to heat the water in the water circulation system to maintain the water temperature in the current water circulation system within a preset temperature range; the target heating power is less than the preset heating power.

[0021] Optionally, the process of circulating and heating the water in the water circulation system further includes:

[0022] When a decrease in the water volume within the water circulation system is detected, the current water volume within the water circulation system is determined to obtain the real-time water volume.

[0028] Optionally, the humidifier heating control method further includes:

[0040] As can be seen, this application first detects the current water volume of the humidifier, wherein the current water volume includes at least the water volume of the humidifier water tank, then determines the preset heating power and preset heating time corresponding to the current water volume, and then controls the heating element to circulate and heat the water in the water circulation system of the humidifier according to the preset heating power, and makes the heating time of the heating element reach the preset heating time; wherein the water circulation system includes the humidifier water tank, the external water channel of the water tank, and the water channel of the wettable substrate; the heating element is disposed in the water circulation system of the humidifier. This application, when heating and sterilizing a humidifier, takes into account the characteristics of the humidifier and does not directly detect the water temperature. Instead of using a temperature sensor to detect the water temperature, it determines the heating power and heating time of the current heating element based on the water volume of the humidifier. Since the relationship between the heating power and heating time and the corresponding water volume is preset, the heating power and heating time suitable for the current sterilization mode can be directly found based on the current water volume, thereby achieving effective sterilization. In addition, there is no need to use independent sterilization elements such as bactericides or ultraviolet sterilization, thus reducing power consumption and consumables.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] This application discloses a humidifier heating control method. See also Figure 1 As shown, the method includes:

[0048] Step S11: Detect the current water volume of the humidifier, wherein the current water volume includes at least the water volume in the humidifier's water tank.

[0049] In this embodiment, when controlling the heating and sterilization of the humidifier, the water volume in the entire water circulation system of the humidifier is first detected to obtain the current water volume; wherein, the water in the water circulation system may specifically include water in the water tank, water on the humidifiable and wettable substrate or base, water in the water pipes, etc.

[0050] For details, see Figure 2 As shown, Figure 2 The structure of a water circulation system in a humidifier and the direction of water flow for water circulation heating are shown. By heating the water through water circulation and maintaining the water in the entire water circulation system within a certain temperature range for a preset time, the entire water circuit of the machine can be sterilized.

[0051] In one specific embodiment, the humidifier has the structure of an evaporative humidifier. This humidifier has a humidifiable and wettable substrate or base. Water is drawn from a water tank by a water pump, and a heating element, such as a pipe-type PTC (Positive Temperature Coefficient) element, is installed on the water pipes. Alternatively, the heating element can be placed inside the water tank. Furthermore, the water pipes connect to a water distribution slot at the top of the wettable substrate (such as a filter screen, fabric, mesh, or non-woven fabric), allowing water to flow into the distribution slot. The distribution slot receives the water and distributes it evenly across the wettable substrate. Additionally, the humidifier has an internal fan that draws in air from the outside and directs it to the wettable substrate, thus carrying the moisture from the substrate out into the external space, thereby achieving air humidification.

[0052] Specifically, detecting the current water volume of the humidifier can include: detecting the current water volume and level in the humidifier's water circulation system using a water level sensor and a float switch to obtain the current water volume and level. In this embodiment, the water level sensor can be used to detect the current water level in the humidifier's water circulation system, thereby obtaining the current water volume and level information of the humidifier. The water volume can be detected before water circulation is started, at which time the water volume of the entire unit is mainly concentrated in the water tank. Therefore, the water volume detected at this time is the current water volume of the humidifier, that is, the total water volume of the humidifier. After water circulation is started, at least some of the water in the water tank will enter the water path or onto a wettable substrate or base, and the water volume in the water tank will continue to decrease for a short period of time. Alternatively, it can also be detected by weight, such as weighing the humidifier empty and comparing its weight after adding water, using the density of water (1 kg / L) to convert the weight into volume; or by detecting the water volume in the humidifier's water circulation system through the water pump flow rate and running time. By using a combination of water level sensor and float switch detection, weight detection, or water pump flow time sequence analysis, the current water capacity of the water circulation system (water tank, pipes, filter screen, etc.) can be obtained in real time, which can accurately reflect the actual water distribution status inside the humidifier.

[0053] Step S12: Determine the preset heating power and preset heating time corresponding to the current water volume.

[0054] In this embodiment, after detecting the current water volume of the humidifier, a preset heating power and preset heating duration corresponding to the current heating element and current water volume in the humidifier can be matched from a preset schedule. Specifically, the preset heating power and preset heating duration are heating power and heating duration pre-set for humidifiers in sterilization mode at different water volumes based on historical heating data.

[0055] The system can dynamically adjust parameters to accommodate changes in water volume at different usage stages (such as initial filling, mid-cycle water replenishment, and filter saturation). This ensures the sterilization process is always adapted to the current water volume, while also improving sterilization efficiency and preventing insufficient heating power (incomplete sterilization) or excessive power (energy waste) due to water volume estimation errors. For example, when the water volume is small, reducing the heating power and shortening the time can still achieve the target sterilization temperature; when the water volume is large, higher power can be used for rapid heating.

[0056] In one embodiment, this application pre-creates a preset timetable for different types of heating elements based on a preset temperature change curve. This preset timetable can be used even when a temperature sensor is not required on the humidifier. The timetable records the correspondence between different heating durations and heating power. The preset temperature change curve is the water temperature change curve under different water volumes and corresponding preset heating powers, i.e., the temperature change curve under different water volumes and heating powers. The preset heating duration is the duration determined in advance based on different water volumes and corresponding preset heating powers when the water temperature in the water circulation system reaches a preset temperature threshold. Through the pre-created preset timetable, the heating power and heating duration matching the current operating state can be directly extracted during real-time heating and sterilization control, eliminating the need for real-time power and duration calculations or real-time temperature calculations. This overcomes the limitations of traditional humidifiers that rely on temperature feedback, improves the efficiency of heating and sterilization control, enhances system stability, and avoids parameter fluctuations caused by real-time calculation errors (such as sensor noise and environmental interference), thereby ensuring a smooth and controllable heating process.

[0057] In one embodiment, the process of obtaining the preset temperature change curve may include: pre-collecting water temperature values ​​of different types of heating elements under different water volumes and multiple initial heating powers, and generating a curve showing the change of the water temperature value with the initial heating time to obtain the initial temperature change curve. The above steps can be performed by pre-programming the pre-collected data and program algorithms into the hardware program before the humidifier leaves the factory. During humidifier use, the humidifier may not be equipped with a temperature sensor. When it receives user feedback information regarding water temperature, such as 50℃, 60℃, or 70℃, it adjusts the heating parameters in the initial temperature change curve according to the feedback information to obtain the corresponding preset temperature change curve for the heating element; the heating parameters include the initial heating power and the initial heating time.

[0058] In one embodiment, the process of obtaining the preset temperature change curve may specifically include: detecting and collecting (only needed when initially generating the temperature change curve) historical water temperature values ​​for different types of heating elements under different water volumes (e.g., 3L) and multiple different initial heating powers, and then generating a curve showing the change of historical water temperature values ​​with multiple preset initial heating durations to obtain the initial temperature change curve. When user feedback information regarding water temperature is received, such as when the user manually reports "overheated" or "insufficient" water temperature through a preset interface (e.g., a button or an app), the heating parameters can be fine-tuned. Specifically, based on the user's feedback information and using a thermal balance model, the heating parameters (i.e., initial heating power and initial heating duration) in the initial temperature change curve can be adjusted to obtain the preset temperature change curve for the corresponding heating element. This curve can be stored in a preset storage space, such as an EEPROM (Electrically Erasable Programmable Read-Only Memory).

[0059] The calculation formula for the heat balance model is as follows:

[0060]

[0061] In the formula, P is the heating power, k is the thermal conductivity coefficient, A is the heat dissipation area, ΔT represents the difference between the water temperature and the ambient temperature, m represents the water volume, and c is the specific heat capacity. This represents the rate of temperature change.

[0062] Specifically, the temperature change curve can be solved using numerical methods (such as the Euler method), and the heating power can be dynamically adjusted based on the heat balance model.

[0063] For example, when the water volume in the temperature change curve is 3L, the corresponding heating power is 250W (which is the full power of the heating element), and the heating time is t (e.g., 20 minutes). This heating parameter can cover the temperature rise requirement of the maximum water volume (3L).

[0064] The preset heating time can be calculated using thermodynamic formulas. Specifically, it can be calculated in advance by taking into account factors such as water tank capacity, initial water temperature (default room temperature), heating power (250W), and water's specific heat capacity (4.186kJ / kg·℃) to determine the time required to reach the target temperature (e.g., 60℃). For example, when heating at full power (250W), the continuous heating time is T1 minutes, and the formula is T1=Q / (P×η), where Q is the total heat demand and η is the thermal efficiency.

[0065] Step S13: Control the heating element to circulate and heat the water in the water circulation system of the humidifier according to the preset heating power, and make the heating time of the heating element reach the preset heating time; the water circulation system includes the humidifier water tank, the external water channel of the water tank and the water channel of the wettable substrate; the heating element is disposed in the water circulation system of the humidifier.

[0066] In this embodiment, after determining the preset heating power and preset heating duration that match the current water volume, an adjustable power heating circuit, such as PWM (Pulse Width Modulation) or a microcontroller unit (MCU), can control the PTC heating element to circulate and heat the water in the humidifier's water circulation system according to the preset heating power and continue for the preset heating duration, thereby achieving a sterilization effect on the entire water circuit. The preset heating duration is the time when the water temperature in the water circulation system reaches a preset temperature threshold, which is determined in advance based on different water volumes and corresponding preset heating power (e.g., 250W).

[0067] It should be noted that the heating element is located in the humidifier's water circulation system, and the heating element uses at least two different heating powers when reaching the preset heating time. By dynamically switching between at least two heating powers during the preset heating time (e.g., using high power to quickly raise the water temperature in the initial stage, and then switching to low power to maintain thermal balance), it is possible not only to match differentiated heat load requirements according to the decreasing water volume characteristics and avoid energy waste caused by constant power, but also to suppress the risk of overheating in local water circuits caused by continuous high power heating through a stepped power reduction strategy. This reduces the temperature difference fluctuation between the substrate water circuit and the external water circuit, improving heating uniformity and extending the life of the heating element. Furthermore, this multi-stage power coordination mechanism can achieve dual protection against boiling and dry burning without relying on temperature sensors, thus significantly enhancing system safety and environmental adaptability.

[0068] In this embodiment, the process of circulating and heating water in the water circulation system may further include: when a decrease in the water volume in the water circulation system is detected, determining the current water volume in the water circulation system to obtain the real-time water volume; calculating the difference between the real-time water volume and the current water volume, and the ratio of the difference to a preset capacity; calculating the product of the ratio and a preset compensation time, and shortening the preset heating time based on the product. It is understood that if a change in the water volume of the water circulation system is detected during the heating control of the humidifier, continuing to heat according to the preset heating time determined based on a preset temperature change curve would result in a temperature higher than the required sterilization temperature, thereby increasing power consumption. Therefore, the expected heating temperature can be achieved by shortening the heating time. Specifically, when a decrease in the water volume in the water circulation system is detected, the decrease can be calculated first, then the ratio of the difference to the preset capacity and the product of the ratio and the preset compensation time can be calculated, thereby dynamically adjusting the preset heating time. For example, when a decrease in water volume is detected in the water circulation system (e.g., a drop in water level of 0.5L), the time t can be shortened proportionally (e.g., shorten by 5 minutes for every 0.5L decrease).

[0069] In this embodiment, the process of circulating and heating water in the water circulation system may further include: when a drop in the water level is detected in the water circulation system, determining the current water level in the water circulation system to obtain a real-time water level; calculating the difference between the real-time water level and the current water level, and the ratio of the difference to a preset water level; calculating the product of the ratio and a preset compensation time, and shortening the preset heating time based on the product. In this embodiment, similar to the reduction in water volume, when a drop in the water level of the water circulation system is detected (e.g., a drop of 1 cm), meaning a reduction in water volume, the preset heating time needs to be shortened. Specifically, the time t can be shortened proportionally (e.g., shortening by 5 minutes for every 1 cm reduction).

[0070] The water circulation system can refer to the various main hardware components through which water flows in a humidifier. For example, in an evaporative humidifier, water in the tank can be guided to the wettable substrate by gravity or a water pump through a medium, water pipe, waterway, or water conduit. Therefore, the water circulation system includes at least one of the following: a water tank, an external water path, and a water path to the wettable substrate. The external water path refers to the location or space where water flows outside the water tank and the wettable substrate, such as a water pipe, water pump, or conductive medium. Starting the water circulation system involves circulating water between the water tank and the wettable substrate, for example, by opening the water tank's drain valve or the water pump. Closing the water circulation system involves stopping the water circulation between the wettable substrate and the water tank, for example, by closing the water tank's drain valve or the water pump. It is conceivable that there is a short delay in the water circulation system during the brief moment of opening or closing the water tank's drain valve or the water pump; this delay is not excluded in the embodiments.

[0071] In this embodiment, the process of circulating and heating water in the water circulation system may further include: when a change in the water volume within the water circulation system is detected, determining the current water volume in the water circulation system to obtain a target water volume; if the target water volume is less than a first capacity threshold, reducing the heating power of the current heating element; if the target water volume is greater than a second capacity threshold, increasing the heating power of the current heating element; wherein the second capacity threshold is greater than the first capacity threshold. That is, the water volume change in the water circulation system is monitored in real time. If the current water volume exceeds the second capacity threshold, the heating power of the heating element is increased to achieve rapid heating; if the current water volume is less than the first capacity threshold, the heating power of the current heating element is reduced to prevent power consumption. In other words, when the water volume is low, the heating power is reduced; when the water volume is high, the heating power is increased.

[0072] As can be seen, in this embodiment, the current water volume of the humidifier is first detected, wherein the current water volume includes at least the water volume of the humidifier water tank. Then, the preset heating power and preset heating time corresponding to the current water volume are determined. Then, the heating element is controlled to circulate and heat the water in the water circulation system of the humidifier according to the preset heating power, and the heating time of the heating element reaches the preset heating time. The water circulation system includes the humidifier water tank, the external water channel of the water tank, and the water channel of the wettable substrate. The heating element is disposed in the water circulation system of the humidifier. In this embodiment of the application, when heating and sterilizing a humidifier, the characteristics of the humidifier are taken into account. Instead of directly detecting the water temperature, such as without using a temperature sensor to detect the water temperature, the heating power and heating time of the current heating element are determined based on the water volume of the humidifier. Since the relationship between the heating power and heating time and the corresponding water volume is preset, the heating power and heating time suitable for the current sterilization working mode can be directly found based on the current water volume, thereby achieving effective sterilization. In addition, there is no need to use independent sterilization elements such as bactericides or ultraviolet sterilization for sterilization, thus reducing power consumption and consumables.

[0073] This application discloses a specific humidifier heating control method. (See also...) Figure 3 As shown, the method includes:

[0074] Step S21: Detect the current water volume of the humidifier, wherein the current water volume includes at least the water volume in the humidifier's water tank.

[0075] Step S22: Determine the preset heating power and preset heating time corresponding to the current water volume.

[0076] Step S23: Control the heating element to circulate and heat the water in the water circulation system of the humidifier according to the preset heating power, and make the heating time of the heating element reach the preset heating time; the water circulation system includes the humidifier water tank, the external water channel of the water tank and the water channel of the wettable substrate; the heating element is disposed in the water circulation system of the humidifier.

[0077] Step S24: Control the heating element to continue heating the water in the water circulation system to maintain the water temperature in the water circulation system within a preset temperature range.

[0078] In this embodiment, after the heating element has reached the preset heating time, the heating element can be further controlled to continue heating the water in the water circulation system, thereby maintaining the water temperature in the water circulation system within the preset temperature range to achieve a better sterilization effect. That is, after reaching the preset time, the heating element continues to work for a period of time to maintain the water temperature within a target temperature range.

[0079] Specifically, maintaining the water temperature in the water circulation system within a preset temperature range may include: using pulse heating technology and controlling the heating element to heat the water in the water circulation system according to a target heating power, so as to maintain the current water temperature in the water circulation system within the preset temperature range; the target heating power is less than the preset heating power.

[0080] For example, a reduced-frequency pulse heating method (such as 50W cycle start-stop) can be used, and the residual temperature can be maintained by controlling the duty cycle.

[0081] For example, reducing the heating power to 50% (125W) and operating intermittently with a cycle of t on (e.g., 10 seconds to activate) and t off (e.g., shut down after 50 seconds), and continue for the total duration (t_total).

[0082] In this embodiment, the method may further include: controlling the humidifier's fan to operate according to a preset working mode, and reducing the fan speed or pausing the fan's operation when the water temperature in the water circulation system is detected to reach the preset temperature threshold. In this embodiment, the water temperature can also be indirectly affected by controlling the fan speed and / or operating time. For example, when the water temperature is detected to reach the target temperature (i.e., the preset temperature threshold), the fan speed is reduced or the fan operation is paused, thereby slowing heat loss and maintaining the water temperature.

[0083] In addition, the coordinated operation time of the heating element and the fan can be preset to ensure that the water temperature is maintained within the preset range.

[0084] In this embodiment, the process of circulating and heating water in the water circulation system may further include: controlling the circulation speed of the water in the water circulation system through a fixed flow valve; and / or adjusting the heat exchange efficiency of the water circulation system by controlling the flow rate of the water pump. In this embodiment, considering that the calculation of water volume can be equivalently replaced by the flow rate of the water pump (i.e., pump flow rate), a mathematical relationship between the pump flow rate and the heating power can be established:

[0085] Flow rate Q (L / h) ≤ (P×3600) / (c×ΔT×ρ);

[0086] Where c = 4186 J / kg·℃, ρ = 1 kg / L, and ΔT is the target temperature rise.

[0087] For example, if a 5°C temperature rise needs to be maintained, the maximum flow rate is approximately 250×3600 / (4186×5)≈43L / h. The circulation speed can be limited by a fixed flow valve so that the water can obtain sufficient heat when it flows through the PTC element.

[0088] Specifically, the heat exchange efficiency in the water circuit can be adjusted by controlling the water pump flow rate. For example, when the water temperature needs to be increased, the water pump flow rate can be reduced, thereby increasing the residence time of the water near the heating element. Alternatively, when the water temperature needs to be maintained, the water pump flow rate can be increased, thereby promoting a more uniform distribution of heat.

[0089] Alternatively, the heating power of the heating element can be kept at a fixed value (e.g., 250W) based on the water pump flow control. Simultaneously, the corresponding heating time and cycle time can be set according to the interaction between the water pump flow and the heating power, which can be controlled by timing (e.g., using a timer).

[0090] The specific heat exchange efficiency control process is as follows: First, obtain the water pump flow rate (Q), which is the amount of water circulating per unit time (unit: liters / second); heating power (P), which is the fixed power of the heating element; target temperature difference (ΔT), which is the difference between the preset temperature and the initial temperature; and specific heat capacity (c) of 4.18 J / g·℃.

[0091] Next, calculate the heating time (t):

[0092]

[0093] The water volume (m) can be calculated using flow rate and time: m = Q·t;

[0094] Finally, maintain the water level and adjust the pump flow rate to control heat exchange efficiency.

[0095] For more detailed processing procedures of steps S21 to S23, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0096] As can be seen, in this embodiment of the application, the entire humidifier heating and sterilization control process is divided into two heating stages. The first heating stage (rapid heating) is based on the preset heating power and preset heating time determined by the water volume. The second heating stage (maintenance stage) is to maintain the water temperature within a preset temperature range, thereby achieving a better sterilization effect.

[0097] By using a preset temperature change curve and staged heating control (such as initial high power for rapid heating and subsequent low power to maintain temperature), and by controlling the water temperature of the water system within the effective sterilization range (such as 60℃~80℃) for a specified duration, the sterilization effect can be improved. The high temperature duration is sufficient to inactivate common pathogens (such as Escherichia coli and mold spores), which meets hygiene standards.

[0098] This application also discloses a humidifier, comprising: a water volume sensor for detecting the current water volume of the humidifier, the current water volume including at least the water volume of the humidifier water tank; a memory for determining a preset heating power and a preset heating time corresponding to the current water volume; and a control circuit for controlling a heating element to circulate and heat the water in the water circulation system of the humidifier according to the preset heating power, and to ensure that the heating time of the heating element reaches the preset heating time; the water circulation system includes the humidifier water tank, an external water path of the water tank, and a water path for a wettable substrate; the heating element is disposed in the water circulation system of the humidifier. This humidifier can achieve effective sterilization, and furthermore, it eliminates the need for independent sterilization elements such as bactericides or ultraviolet sterilization, thus reducing power consumption and consumables.

[0099] Furthermore, embodiments of this application also disclose an electronic device, Figure 4 This is a structural diagram of an electronic device 20 according to an exemplary embodiment. The content of the diagram should not be construed as limiting the scope of this application.

[0100] Figure 4 This is a schematic diagram of the structure of an electronic device 20 provided in an embodiment of this application. Specifically, the electronic device 20 may include: at least one processor 21, at least one memory 22, a power supply 23, a communication interface 24, an input / output interface 25, and a communication bus 26.
