Description

Humidifier, computer-readable storage medium in humidifier 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 has a simple humidifying function and lacks intelligent control. When the space is too small, the humidity of the whole space is easy to be too high by using large humidification power, and the humidifier is frequently started and stopped, so that the service life of the humidifier can be rapidly shortened; the use of a small humidification power may result in reaching the control target over a long period of time, and the humidification is uneven and the experience is poor.

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

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

In patent document CN201010148967, humidity detected by a humidity sensor is provided as an electric signal, and the control unit performs PID calculation of proportion, integral, and derivative based on the humidity value and a preset target set value to quickly reach the target humidity.

Patent document CN202110130355 obtains a difference value between the current indoor humidity and the target humidity, and if the difference value is greater than a threshold value, adds a product of the difference value and a coefficient to the current humidity increase speed to obtain a target humidity increase speed; if the difference is smaller than the threshold value, subtracting the current humidity increasing speed from the product 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 acquiring corresponding humidification power for humidification according to the target humidity increasing speed. The idea is simplified in that if the difference is large, the humidity increasing speed is increased by increasing the power; if the difference is small, the humidity increase rate is reduced by reducing the power. The method belongs to the design idea that the difference value is positively correlated with the humidity increasing speed, and therefore the effect of quickly approaching the target humidity is achieved.

Although the humidification strategy is set to achieve the aim of rapidly approaching the target humidity, the current size of the working space where the humidifier is located cannot be judged, the power suitable for the current size of the space cannot be automatically selected according to the size of the space, and the AI strategy cannot solve the problem that a consumer does not know how to select the humidification gears according to the space.

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 diagram 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 operations of:

s11, first target information in a space where the humidifier is located is obtained, and the first target information is used for representing the humidity change degree of the space.

In this embodiment, the humidifier may be an ultrasonic humidifier, a pure humidifier, an electrical heating humidifier, an immersion electrode humidifier, or a cold mist humidifier, and the specific type of the humidifier is not limited in this embodiment, where the mist 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 indicate the humidity change condition of the space. For example, the expression of the humidity change degree may be the humidity increment within a fixed time (e.g., a first set time), i.e., the rising value of the humidity; or the time required by the fixed humidity increment can be used for expressing, in this case, the machine works at a fixed power, and when the ambient humidity rises by a fixed value, the longer the used time is, the larger the space is; it can also be expressed in terms of the rate of humidity increase, when the degree of humidity change is the ratio of humidity increase to time, or even the differential/integral of the ratio; or expressed by a humidity rising curve, namely a rising value of the environmental humidity within a period of time, to form a change curve.

In the above, the humidity information in the located space may be obtained by any means, for example, the humidity information may be manually input, queried through an external device with a humidity detection function in a network, or obtained by a humidity detection module provided in the humidifier itself, which is not limited herein. The setting of the first setting time may be derived by the programmer by integrating the sensitivity and the target control interval, and may be, for example, 10 minutes, 30 minutes, 60 minutes, and so on, and the setting of the present embodiment is preferably set to 30 minutes.

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

In the embodiment, the size of the space is indirectly reflected through the humidity change degree, specifically, the establishment of the first rule depends on the rule that the larger the space is, the less obvious the humidity change degree in the space is under the same fog output condition/the same power value, in other words, the humidity change degree is inversely related to the size of the space; the larger the space is, the larger the output fog output amount/power value is, the positive correlation between the output fog output amount/power value and the humidity change degree is, and accordingly, an AI intelligent regulation and control rule that the humidity change degree and the fog output amount are inversely correlated is set, so that the humidifier can indirectly sense the size information of the space according to the humidity change degree, further the proper power is automatically selected to regulate and control the size of the fog output amount, the fog output amount at the fog outlet can be matched with the humidification requirements of the space, and the intelligent humidification suitable for various spaces with different sizes is achieved.

Figure 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 quick matching when operating in step S12, 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 of 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 a humidifier is located, wherein the first target information is used for representing the humidity change degree of the space within a first set time;

In the optional embodiment, the operating power of the appropriate current space can be quickly selected according to the humidity change degree in a grading and matching mode, so that the quick regulation and control effect is achieved. In the above, the setting timing of the operation mode does not necessarily need to be written following the program entry, and the entry may be implemented by human-computer interaction before or after step S11, even during the operation of step S121.

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

As a modification of this embodiment, as shown in fig. 3, after the step S121 is executed to select the power value corresponding to the operation mode, the following operations may be further executed for fine adjustment:

s1212, acquiring the current environment humidity of the space;

step S1213, calculating a first difference value between the current environment humidity and the target humidity value;

step s1214, according to the first difference, adjusting the power value in the selected working mode by a second rule, and then operating the selected working mode, where the second rule includes that the first difference is positively correlated with the power value.

In this modification, the power value parameter in each operation mode (i.e., each power step) is configured to be variable and to vary in accordance with the degree to which the ambient humidity approaches the target humidity value, and this is done in order to gradually decrease the amount of mist generated from the humidifier when 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%), and to configure the power value parameter in each operation mode to vary in accordance with the degree to which the ambient humidity approaches the target humidity value, since different environments require different amounts of mist generated to maintain the humidity at the target humidity value.

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

step S12 further includes:

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

The application schemes are exemplified as follows:

the machine sets 12 working modes: the first pattern … … and the second pattern … … correspond to a space of 10 square meters and 20 square meters … …, respectively. Presetting 12 curves measured by working of the humidifying power of heating 450W + ultrasonic atomization current 800hA in different spaces, wherein the curves are a curve I and a curve II … …; the machine works for 30 minutes by heating 450W + ultrasonic atomization current 800hA, detects the change value of the humidity in the period to form a curve K, compares the curve K with the 12 curves preset in the front, finds out the curve with the highest matching degree with the curve K, and works in the working mode corresponding to the curve.

Fig. 4 shows another 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 runs after step S121 and includes:

s1221, when the current environment humidity of the space reaches a humidity control upper limit, stopping fog generation, wherein the humidity control upper limit is configured to be the sum of a target humidity value and a set numerical value;

step s1222, after the fog is stopped, if it is detected that the current ambient humidity drops below a humidity control lower limit, the downshift operation is performed on the basis of the gear of the current operating mode, where the humidity control lower limit is configured as a difference between the target humidity value and a set value.

In this modification, the setting of the target humidity value may be selected according to actual needs, and at this time, 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 from the target humidity value, wherein 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 used as the upper limit and the lower limit. In this modification, the downshift operation may be a downshift by only one gear, or may be a downshift by two gears or even more, and is not limited herein.

In the modification shown in fig. 4, the idea is to assist in correcting the gear selection by controlling the upper limit of humidity. Specifically, under the framework that a proper gear is selected periodically through a humidity change degree interval, if the humidifier can humidify the ambient humidity to the upper limit, the selected gear is slightly higher than the actual requirement, so that the humidification is suspended without avoiding excessive tide, and the gear is lowered to humidify when the ambient humidity returns to the lower limit, so that 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 runs 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;

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

In this refinement, when the humidity change degree is expressed in increments of humidity for a fixed time (first set time), the second target information is expressed as the humidity change degree of the space for a second set time given by the programmer according to the target control, preferably designed to be less than the first set time, for example, 10 minutes. Similarly, the upshift operation may be only one gear upshift, or may also be two or more gear upshifts, which is not limited herein.

The improved scheme is characterized in that the humidity change of the user is monitored for a period of time, if the humidity change is too low, the selected gear is slightly low for actual requirements, and therefore the gear is corrected to be proper in power through the gear-up operation.

The invention can be implemented independently or combined in any order for several modifications shown in fig. 3 to 5.

As another optional embodiment of the humidification control method of the present invention, the humidifier type in this optional 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 uniform humidification and air freshening effects, and the cold mist generated by the atomizing device 62 is pushed by the wind power of the fan 61, mixed with the steam generated by the heating device 63 heating the water, and then sent to the mist outlet 64.

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

In the above, the lower limit of 40 ℃ is to ensure that at least enough temperature difference exists between the mist outlet temperature of the mist outlet and the ambient temperature, the temperature difference can enable hot air flow generated by the humidifier to rapidly rise and diffuse outwards, and cold air flow in the space flows to the position of the heater under negative pressure, so that rapid diffusion and uniform diffusion of water mist sprayed from the mist outlet are realized. The upper limit of 70 ℃ is to ensure a safe temperature for the mist to exit, so that the mist does not burn a person due to too high a temperature.

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

It should be noted that 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 ℃, preferably 50 ℃ to 65 ℃ for optimal diffusion.

As a modification of this alternative embodiment, as shown in fig. 7, a humidity detection module 71 may be disposed on the humidifier to monitor the first target information or the ambient humidity of the space. In the scheme, because the humidifier works in a hot fog state at the temperature of 40-70 ℃, fog is uniformly diffused, and the ambient humidity at each position in the space is basically the same, a distributed sensor array is not needed, 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 hot fog state can be realized by adjusting the air output of the fan to match with the heating power so as to control the temperature of the fog outlet in the corresponding range.

In this implementation, the amount of air supply can be adjusted by increasing the control circuit of the amount of air supplied by the fan, for example, by adding a voltage conversion circuit to adjust the supply voltage of the fan, or by adjusting the rotation speed of the fan through a frequency modulation circuit. The air supply quantity is set on a program and is matched with the heating power of the heating device in real time, so that the cold mist driven by air and the hot mist generated by heating water by the heating device are mixed to reach a temperature range of 40-70 ℃, for example, the air quantity of A 'is sent when the heating power is A, the air quantity of B' is sent when the heating power is B, and finally the temperature of the mist outlet is controlled in a corresponding range. The voltage conversion circuit and the frequency modulation circuit belong to conventional circuits and are not expanded here.

As another implementation manner of the hot mist state, the air output of the fan can be kept unchanged, at this time, the fan does not need to add an extra circuit, cost control is achieved, and meanwhile, the heating power of the heating device is limited in a set interval, wherein the set interval can be matched with the fixed air output of the fan, so that the temperature of the mist outlet is controlled in a corresponding interval, for example, the lower limit of the heating power is set to be matched with the fixed air output to enable the mixed hot mist to reach 40 ℃, and the upper limit of the heating power is set to be matched with the fixed air output to enable the mixed hot mist to reach 70 ℃, so that the purpose can be achieved only through parameter adjustment.

As a third improvement of this alternative embodiment, the hot fog state further includes that the water temperature heated by the heating device reaches the boiling point, for example, the water tank temperature is heated to 100 ℃ under the standard atmospheric pressure, so as to realize the sterilization function.

Further, the control step S11 is executed after the water temperature reaches the boiling point and the current ambient humidity reaches the lower limit of humidity control, and the humidifier is operated in the hot fog state at a fixed power after the water temperature reaches the boiling point and before the current ambient humidity does not reach the lower limit of humidity control. According to the scheme, after the water temperature reaches the boiling point and before the current environment humidity does not reach the humidity control lower limit, the humidifier operates at fixed power (for example, full-power operation), AI intelligent control is performed only when the lower limit is close to the target value, the computing resources of a processing system in the humidifier can be saved, the target is approached at the fastest speed in the early stage, and power selection is performed when the target is approached quickly.

Furthermore, the humidifier is controlled to drive the atomizing device to generate fog at low power before the water temperature reaches the boiling point, so that micro-humidification is performed on the space at the initial stage, and misunderstanding of a user caused by the fact that fog does not occur before the water temperature reaches the boiling point is avoided. For example, the humidity is equal to or higher than 58% at the time of starting, and forced humidification is carried out for 3 minutes at the current of 340mA of the cold fog.

More preferably, the driving the atomizer to emit mist at low power further comprises:

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

and under the condition that the second difference value is lower than a second set threshold value, controlling the working current of the atomization device to gradually increase along with the rise of the water temperature.

In the preferable scheme, when the difference value between the water temperature and the boiling point temperature is lower than a second set threshold, the water temperature is close to the boiling point, the working current of the atomizing device is controlled to gradually increase along with the rise of the water temperature, the mist outlet quantity is gradually increased until the water temperature reaches the boiling point, and then the full-power operation (the maximum mist outlet quantity) is carried out, so that the gradual mist increasing effect is achieved, and the phenomenon that the user experience is declined due to the fact that the mist outlet quantity is changed suddenly 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 according to the humidity intervals from low to high, the current parameters of the current rising modes are configured to be in ascending steps and the upper limit is gradually reduced from high to low. And under the condition that the second difference is lower than a second set threshold, the machine firstly detects the current environment humidity, searches for a falling humidity interval according to the current environment humidity, and controls the current to rise step by step according to the rising step corresponding to the humidity interval and the upper limit. The purpose of doing so is to prevent that the fog volume of cold fog increases too fast before the temperature of going out fog is not up to standard and leads to the fog behind the fog to fall in humidifier periphery, causes near moisture overweight influence humidity and detects the rate of accuracy.

For ease of understanding, the following examples are given to aid understanding:

FIG. 8 shows a schematic flow diagram of the present invention before the water temperature reaches the boiling point.

As shown in FIG. 8, when the device is turned on, the humidity is greater than or equal to 58%, and the atomization device is forcedly humidified for 3 minutes at the current of 340mA of the cold mist.

When the humidity is less than 58% during starting, if the water temperature is 1-80 ℃, the PTC (heating device) works at full power, and meanwhile, the cold mist is humidified by 340mA current (if the humidity is more than 65% in the humidification process, the process needs to be kept for 3 minutes, and the operation is stopped); if the water temperature is 80-100 ℃, the PTC is operated at full power while the cold mist is humidified with an initial current of 340mA, after which:

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

when the current ambient humidity is between 40 and 50 percent, every 0.1 second, the cold fog current is increased by 1.3mA till reaching 600 mA;

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

FIG. 9 shows a schematic flow diagram of the present invention after the water temperature reaches boiling point.

As shown in FIG. 9, after the water temperature is 100 ℃, if the ambient humidity is less than 55%, the cooling mist work is carried out by using 450W PTC +800 mA.

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

And if the time from starting to humidity reaching 55% is less than 30min, operating according to the mode three.

When the ambient humidity reached 65%, the machine stopped fogging. When the ambient humidity again drops to 54%, the machine resumes fogging. The mode of operation at this time is a mode in which the amount of humidification is lower by one step than that in the previous operation, for example, the mode one is changed to the mode two.

When the operation time exceeds 10min, the humidity is not increased all the time, and the mode is increased forward by one gear, for example, the mode is changed from the mode three to the mode two.

The working mode is that different heating power and atomizing power are intelligently selected according to different environmental humidity. The heating power and the atomization power of the mode I, the mode II and the mode III … … are gradually reduced, and the fog quantity is gradually reduced.

Here, an example is given of an operation form when the power value of each operation mode is finely adjusted. The numerical values listed below are merely representative of control concepts and are not final execution values. The number of modes may be changed to more various modes depending on the machine to be actually used.

For example:

the first mode is as follows: 450W PTC +800mA cold fog is used for 55 percent; 400W PTC +700mA cold fog is used for 56 percent; 350W PTC +600mA cold fog is used for 57 percent; 300W PTC +500mA cold fog is used for 58 percent; 250W PTC +480mA cold mist is used for 59 percent; 200W PTC +420mA cold fog … … is used for 60 percent

And a second mode: 400W PTC +700mA cold mist is used for 55 percent; 56% uses 350W PTC +650mA cold fog; when the content of the cold mist is 57 percent, 300W PTC +600mA cold mist is used; 250W PTC +550mA cold fog is used for 58 percent; 200W PTC +450mA cold fog is used for 59 percent; 60% using 150W PTC +370mA cold fog … …
