Description

Humidifier, computer readable storage medium therein and humidification control method

Technical Field

The present invention relates to humidification control, and more particularly, to a humidifier, a computer-readable storage medium therein, and a humidification control method.

Background

The conventional humidifier on the market is simpler in humidifying function and lacks intelligent control. When the space is too small, the whole space is easy to be excessively high in humidity by using high humidifying power, and meanwhile, the humidifier is frequently started and stopped, so that the usable life of the humidifier slides down rapidly; the use of small humidification power can lead to reaching the control target only for a long time, and the humidification is uneven, so that the experience is poor.

Patent document CN2018214712594 is a previous solution for my department, which can well solve the problem of water leakage, but lacks an AI intelligent fuzzy function.

In the humidifying method disclosed in patent document CN201911008307, a plurality of humidity gear intervals are established in advance through a list form, a mist output preset value is configured for each gear interval, and in the actual humidifying process, the mist output of the corresponding gear is controlled and output according to the gear in which d0 is through the relative humidity d0 in the humidity sensor chamber, so that intelligent humidifying control is realized.

The patent document CN201010148967 provides the humidity detected by the humidity sensor in an electric signal manner, and the control unit performs PID calculation of the proportional, integral and derivative with the humidity value and the preset target set value, so as to quickly reach the target humidity.

Patent document CN202110130355, by obtaining a difference between the current indoor humidity and the target humidity, if the difference is greater than a threshold value, adds the product of the difference and the coefficient to the current humidity increase rate as the target humidity increase rate; if the difference value is smaller than the threshold value, subtracting the product from the current humidity increasing speed to obtain a target humidity increasing speed; and if the difference value is equal to the threshold value, taking the current humidity increasing speed as the target humidity increasing speed. And then obtaining corresponding humidifying power according to the target humidity increasing speed to humidify. The idea is simplified that if the difference is large, the humidity increasing speed is increased by increasing the power; if the difference is small, the humidity increasing speed is reduced by reducing the power. The design concept of positive correlation of the difference value and the humidity increasing speed is adopted, and the effect of quickly approaching the target humidity is achieved.

According to the scheme, although the humidifying strategy is set to achieve the aim of approaching the target humidity quickly, the size of the working space where the humidifier is currently located cannot be judged, the power suitable for the size of the current space cannot be automatically selected according to the size of the space, and the problem that consumers do not know how to select humidifying gears according to the space cannot be solved by the AI strategy.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 shows a schematic flow chart of the humidification control method of the present invention. As shown in fig. 1, the humidification control method of the present embodiment may include the following operations:

and S11, acquiring first target information in a space where the humidifier is located, wherein the first target information is used for indicating the humidity change degree of the space.

In this embodiment, the humidifier may be an ultrasonic humidifier, a pure humidifier, an electric heating humidifier, an immersed electrode humidifier, or a cold mist humidifier, and the specific type of the humidifier is not limited in this embodiment, where the mist outlet at the mist outlet of the humidifier may be cold mist or hot mist, and is not limited herein.

The humidity change degree referred to in this embodiment may be any information as long as it can represent the humidity change condition of the space. For example, the humidity change degree may be expressed in terms of a humidity increase in a fixed time (e.g., a first set time), that is, a rise value of humidity; the machine can also be represented by the time required for a fixed humidity increment, in which case the machine operates at a fixed power, the longer the time used per rise of ambient humidity by a fixed value, the greater the space; it may also be expressed in terms of a rate of increase in humidity, where the degree of change in humidity is the ratio of the increase in humidity to time, or even the derivative/integral of the ratio; or the humidity rising curve is used for representing the humidity rising value of the environment in a period of time to form a change curve.

In the foregoing, the humidity information in the space may be obtained by any manner, for example, may be manually input, may be obtained by performing a network query through an external device with a humidity detection function, or may be obtained by a humidity detection module set in the humidifier itself, which is not limited herein. The setting of the first setting time may be obtained by integrating the sensitivity and the target control section by the programmer, and may be, for example, 10 minutes, 30 minutes, 60 minutes, or the like, and the present embodiment is preferably set to 30 minutes.

And S12, adjusting the power value of the humidifier or the mist outlet amount at the mist outlet according to the first target information, wherein the first rule comprises that the humidity change degree is inversely related to the mist outlet amount or the humidity change degree is inversely related to the power value, and the power value is used for generating the mist outlet amount.

In this embodiment, the space size is indirectly reflected by the humidity change degree, specifically, the first rule is set up according to the rule that the larger the space is, the less obvious the humidity change degree in the space is, in other words, the humidity change degree is inversely related to the space size under the same mist output condition/same power value; the larger the space is, the larger the output mist output/power value is, the positive correlation is adopted between the output mist output and the power value, and the AI intelligent regulation and control rule of the inverse correlation of the humidity change degree and the mist output is set according to the positive correlation, so that the humidifier can indirectly sense the size information of the space according to the humidity change degree, and further automatically select proper power to regulate the mist output, the mist output at the mist outlet can be matched with the humidification requirement of the space, and the intelligent humidification suitable for spaces with different sizes is achieved.

Fig. 2 shows an alternative embodiment of the humidification control method of the present invention. As shown in fig. 2, the humidification control method may set a plurality of operation modes in advance, and perform rapid matching when the step S12 is performed, specifically, the method includes:

s10, setting a plurality of working modes, wherein each working mode is correspondingly provided with a humidity change degree interval, and the power values operated by the heater in each working mode are different so as to form a plurality of power gears;

s11, acquiring first target information in a space where the humidifier is located, wherein the first target information is used for representing the humidity change degree of the space within a first set time;

and S121, selecting a power value corresponding to the working mode to operate according to the interval in which the first target information falls.

In the alternative embodiment, the operation power of the proper front space can be quickly selected according to the humidity change degree in a grading and matching mode, so that a quick speed regulation effect is achieved. In the above, the setting timing of the working mode is not necessarily written following the program input, but may be input before or after step S11, or even in the running process of step S121 through man-machine interaction.

Fig. 3 shows a further development of this alternative embodiment.

As a modification of this embodiment, as shown in fig. 3, step S121 may further perform the following operations for fine tuning after performing step S1211 to select the power value of the corresponding operation mode:

s1212, acquiring the current environmental humidity of the space;

s1213, calculating a first difference value between the current ambient humidity and a target humidity value;

step S1214, adjusting the power value in the selected working mode according to the first difference value, and operating the power value according to a second rule, wherein the second rule comprises that the first difference value and the power value are positively correlated.

In this modification, the power value parameter in each operation mode (i.e., each power shift position) is configured to be variable and varies with the degree to which the ambient humidity approaches the target humidity value, with the purpose that the amount of mist emitted from the humidifier gradually decreases as the ambient humidity approaches the target humidity value (e.g., 60%), so that the ambient humidity can be maintained at the level of the target humidity value (e.g., at 60%), while the power value parameter in each operation mode is configured to vary with the degree to which the ambient humidity approaches the target humidity value, since the amount of mist emitted required for the different ambient pair humidities to be maintained at the target humidity value varies.

As an alternative to the alternative embodiment of fig. 2, different operation modes may be configured for different space sizes, the heater is preset with a humidity variation degree template of each space under a certain time and power, and the power values operated by the heater under each operation mode are different so as to form a plurality of power gears;

step S12 further includes:

Specifically, the machine presets a plurality of modes of operation, each mode of operation being tailored to a particular environmental space. Meanwhile, the machine presets a humidity rising curve of each specific space under certain time and power. The machine forms a change curve by detecting the rise value of the ambient humidity in a period of time before testing. By comparing the curve with a preset curve, the size of the space can be judged, so that a working mode suitable for the space can be selected.

The application scheme is exemplified as follows:

the machine sets 12 modes of operation: mode one and mode two … … mode twelve correspond to a space of 10 square meters and 20 square meters … …, respectively. The 12 curves measured by the operation of the humidifying power of the heating 450 W+ultrasonic atomizing current 800hA in different spaces are preset, namely a curve I and a curve II … … curve twelve respectively; the machine works for 30 minutes by heating 450 W+ultrasonic atomization current 800hA, a curve K is formed by detecting the change value of humidity in the period, the curve K is compared with 12 preset curves, the curve with the highest coincidence degree with the curve K is found, and the machine works in a working mode corresponding to the curve.

Fig. 4 shows a further modification of the alternative embodiment shown in fig. 2 or an alternative thereto. As shown in fig. 4, step S12 further includes step S122, and step S122 is performed after step S121, and includes:

s1221, stopping mist generation when the current environmental humidity of the space reaches the upper humidity control limit, wherein the upper humidity control limit is configured as the sum of a target humidity value and a set numerical value;

and S1222, if the current environmental humidity is monitored to be lower than the lower humidity control limit after the mist is stopped, executing the downshift operation on the basis of the gear of the current working mode, wherein the lower humidity control limit is configured as the difference between the target humidity value and the set value.

In this modification, the setting of the target humidity value may be selected according to actual needs, and the upper humidity control limit and the lower humidity control limit are set around the target humidity value, for example, by adding or subtracting corresponding values to or from the target humidity value, where the absolute values of the upper humidity control limit and the target humidity value may be the same as or different from the absolute values of the lower humidity control limit and the target humidity value. For example, when the target humidity value is set to 60%, 60% ± 5% is set as the upper limit and the lower limit. In this modification, the downshift operation may be a single downshift, or may be a two-downshift or more.

The improvement shown in fig. 4 is designed to assist in correcting gear selection by means of an upper humidity control limit. Specifically, under the framework that a proper gear is selected periodically through a humidity change degree interval, if the humidifier can humidify the environmental humidity to an upper limit, the selected gear is slightly higher than the actual demand, so that the humidification is suspended without over-tide, and the gear is reduced to humidify when the environmental humidity returns to a lower limit, and the gear correction effect is achieved.

Fig. 5 shows a third modification of the alternative embodiment shown in fig. 2 or an alternative thereto. As shown in fig. 5, the step S12 further includes a step S123, and the step S123 is performed after the step S121, and includes:

s1231, obtaining second target information in a space where the humidifier is located, wherein the second target information is used for representing the humidity change degree of the space;

step S1232, if the second target information is lower than the first set threshold, executing the upshift operation on the basis of the gear of the current working mode.

In this modification, when the humidity change degree is expressed as a humidity increase in a fixed time (first set time), the second target information is expressed as the humidity change degree of the space in a second set time given by the programmer according to the target control, preferably designed to be smaller than the first set time, for example, 10 minutes. Also, the upshift operation may be a single upshift, or may be two upshifts or more, without limitation.

This improvement indicates that the selected gear is slightly lower for the actual demand by monitoring your humidity change for a period of time, if the humidity change is too low, and therefore the gear is modified to the appropriate power by an upshift operation.

The invention can be implemented separately or in any combination of sequences for several modifications shown in fig. 3 to 5.

As another alternative embodiment of the humidification control method of the present invention, the humidifier in this alternative embodiment is selected as a humidifier capable of outputting hot mist, wherein, as shown in fig. 6, the humidifier is provided with a fan 61, an atomizing device 62, a heating device 63 and a mist outlet 64, the atomizing device 62 is preferably an ultrasonic atomizing device to achieve the effect of uniformly humidifying and refreshing air, and cold mist generated by the atomizing device 62 is mixed with steam generated by heating water by the heating device 63 under the driving of wind force of the fan 61 and then sent to the mist outlet 64.

In this alternative embodiment, steps S11, S12 are run in a hot mist state, wherein the hot mist state includes a temperature of the mist outlet being controlled between 40 ℃ and 70 ℃.

In the above, the lower limit of 40 ℃ is to ensure that the mist outlet has enough temperature difference between the mist outlet temperature and the ambient temperature, and the temperature difference can enable the hot air generated by the humidifier to quickly rise and spread outwards, and meanwhile, the cold air in the space flows to the position of the heater under negative pressure, so that the rapid and uniform diffusion of the mist sprayed by the mist outlet is realized. The upper limit of 70 ℃ is to ensure the safe temperature of mist, and the mist cannot scald people due to the excessively high temperature.

The mist output of the traditional ultrasonic humidifier is generally within 300mL/H, because the humidifier sprays cold mist, if the mist output of the cold mist is too large, a large amount of cold mist can quickly sink to the desktop/ground where the humidifier is positioned after being sprayed, and the diffusion effect cannot be achieved. In the alternative embodiment, the problem of diffusion is solved through the temperature of the mist outlet, so that the mist outlet of the humidifier can be large, specifically, the humidifier can realize the mist outlet of more than 1000mL/H by increasing the power of the atomizing device in the range of 40-70 ℃ so as to achieve the ultra-large mist outlet. Step S11 and step S12 are adjusted on the basis of the ultra-large mist output, so that the environment humidity can be changed rapidly, and the environment humidity is enabled to approach the control target ultra-rapidly on the basis of selecting proper power.

In this alternative embodiment, the temperature of the mist outlet may be controlled to be 43 to 67 ℃, 45 to 65 ℃, or 50 to 60 ℃, and preferably 50 to 65 ℃ to achieve the optimum diffusion effect.

As a modification of this alternative embodiment, as shown in fig. 7, a humidity detection module 71 may be provided on the humidifier to enable monitoring of the first target information or the ambient humidity of the space in which it is located. In the scheme, because the humidifier works in a hot fog state in the range of 40-70 ℃, fog is diffused uniformly, and the environmental humidity of each place in the space is basically the same, a distributed sensor array is not required to be arranged, and the humidity in the space can be monitored only by arranging a humidity detection module 71 on the humidifier, so that the cost control is achieved.

As another improvement of this alternative embodiment, the implementation manner of the hot mist state may be to adjust the air supply quantity of the fan to match with the heating power so as to control the temperature of the mist outlet in a corresponding interval.

In this implementation, the air delivery rate may be adjusted by a control circuit that increases the air delivery rate of the blower, such as by increasing a voltage conversion circuit to adjust the blower supply voltage, or by a frequency modulation circuit to adjust the blower speed. By setting the air supply quantity on a program and matching with the heating power of the heating device in real time, the cold fog driven by air and the hot fog generated by heating water of the heating device are mixed and reach a temperature range of 40-70 ℃, for example, the air supply quantity of A 'is supplied when the heating power is A, the air supply quantity of B' is supplied when the heating power is B, and finally, the temperature of a fog outlet is controlled in a corresponding range. The voltage conversion circuit and the frequency modulation circuit belong to conventional circuits, and are not unfolded here.

As another implementation mode of the hot fog state, the air supply quantity of the fan can be kept unchanged, at the moment, the fan does not need to add an additional circuit to achieve cost control, meanwhile, the heating power of the heating device is limited in a set interval, the set interval can be matched with the fixed air supply quantity of the fan so as to control the temperature of the fog outlet in a corresponding interval, for example, the lower limit of the heating power is matched with the fixed air supply quantity to enable the mixed hot fog to reach 40 ℃, the upper limit of the heating power is matched with the fixed air supply quantity to enable the mixed hot fog to reach 70 ℃, and therefore the purpose can be achieved only through parameter adjustment.

As a third modification of this alternative embodiment, the hot mist state further includes a water temperature heated by the heating means reaching a boiling point, for example, a water tank temperature is heated to a high temperature of 100 ℃ under a normal atmospheric pressure, to achieve a sterilization function.

Further, the control step S11 is performed after the water temperature reaches the boiling point and the current ambient humidity reaches the lower humidity control limit, and the humidifier is operated in the hot fog state with a fixed power after the water temperature reaches the boiling point and before the current ambient humidity does not reach the lower humidity control limit. In the scheme, after the water temperature reaches the boiling point and before the current ambient humidity does not reach the humidity control lower limit, the humidifier operates at fixed power (such as full power operation), AI intelligent control is performed only when the lower limit is close to the target value, calculation resources of a processing system in the humidifier can be saved, the fastest speed approaching target is achieved in the early stage, and power selection is performed when the humidifier is close to the fast speed.

Further, the humidifier is controlled to drive the atomizing device to spray at low power before the water temperature does not reach the boiling point, micro-humidification is carried out on the space in an initial stage, and misunderstanding of a user caused by the fact that the water temperature does not spray before the water temperature does not reach the boiling point is avoided. For example, when the machine is started, the humidity is higher than or equal to 58%, and the machine is forcedly humidified for 3 minutes by using cold fog 340mA current.

More preferably, the low power driving of the atomizing device to emit mist further comprises:

acquiring a second difference between the water temperature and the boiling point temperature;

In the preferred scheme, when the difference between the water temperature and the boiling point temperature is lower than a second set threshold value, the water temperature is close to the boiling point quickly, at the moment, the working current of the atomizing device is controlled to gradually increase along with the rising of the water temperature, the mist output is gradually increased until the water temperature reaches the boiling point, then the full-power operation (maximum mist output) is realized, the gradual mist increasing effect is achieved, and the phenomenon that the user experience is slipped down due to abrupt change of the mist output is avoided. Preferably, different current rising modes are set, each current rising mode corresponds to a humidity interval, and when the current rising modes are arranged from low to high according to the humidity interval, the current parameters of the current rising modes are configured to rise and gradually decrease from high to low. Under the condition that the second difference value is lower than a second set threshold value, the machine detects the current ambient humidity first, searches a falling humidity interval according to the current ambient humidity, and gradually controls current rising according to rising steps and an upper limit corresponding to the humidity interval. The purpose of doing so is to prevent that the mist output of the cold mist increases too fast before the mist output temperature does not reach the standard, so that the mist drops on the periphery of the humidifier after the mist output, and the humidity detection accuracy is influenced by the overweight of nearby humidity.

To facilitate understanding, the following examples are given to aid in understanding:

fig. 8 shows a schematic flow chart of the invention before the water temperature reaches the boiling point.

As shown in FIG. 8, the humidity is 58% or more when the machine is started, and the atomizing device forcibly humidifies for 3 minutes by using a cold fog 340mA current.

Under the condition that the humidity is less than 58% when the machine is started, if the water temperature is 1-80 ℃, the PTC (heating device) works at full power, and meanwhile, the cold fog is humidified at 340mA current (if the humidity is more than 65% in the humidification process, the process needs to be kept for 3 minutes, and the work is stopped); if the water temperature is 80-100 ℃, the PTC works at full power, and the cold fog is humidified at 340mA initial current, and thereafter:

under the condition that the current ambient humidity is lower than 40%, the cold fog current is increased by 2.3mA and is increased to 800mA every 0.1 second;

the current ambient humidity is between 40 and 50 percent, and the cold fog current is increased by 1.3mA to 600mA every 0.1 second compared with the current ambient humidity;

the current ambient humidity is between 51% and 57%, and the cold fog current is increased by 0.8mA and is increased to 500mA every 0.1 second.

Fig. 9 shows a schematic flow chart of the invention after the water temperature reaches the boiling point.

As shown in FIG. 9, if the ambient humidity is less than 55% after the water temperature of 100℃is reached, 450W PTC+800mA cold fog is used.

When the environmental humidity value reaches 55%, the machine judges the rising value of the environmental humidity for the first 30 minutes, and when the rising value is more than 8%, the humidifier works in the following mode III; when the rise value is between 5 and 8 percent, the humidifier works in the following mode II; when the rise value is less than 5%, the humidifier operates in the following mode one. Or the machine works with 450 W+ultrasonic atomization current 800hA, the time for every 2% rise of the ambient humidity is T, and when T is more than or equal to 10 minutes, the machine works in the mode I; when T is less than 10 minutes and greater than 5 minutes, the machine operates in mode two; when T.ltoreq.5 minutes, the machine operates in mode three.

And if the time from starting up to 55% humidity is less than 30min, the operation is performed according to the mode III.

When the ambient humidity reached 65%, the machine stopped fogging. When the ambient humidity drops to 54% again, the machine resumes fogging. The mode of operation is selected to be one level lower than the humidification amount of the previous operation, for example, the mode is changed from the mode I to the mode II.

When the running time exceeds 10min, the humidity is not increased all the time, and the mode is shifted forward by first gear, for example, the mode III is changed into the mode II.

The working mode is to intelligently select different heating power and atomization power according to different environmental humidity.
