Description

{HUMIDIFICATION CONTROL METHOD}

The present invention relates to a method for controlling the humidification of an humidifying air purifier or a humidifier, and more particularly, to a humidification control method for dispersing a functional material uniformly in a humidifying space while saving energy and reducing noise.

Generally, a humidifier, which artificially generates and emits moisture to raise the humidity of the room, includes a heating type humidifier in which water vapor generated by heating water stored in a water tank to a predetermined temperature is spontaneously sprayed into the room, An ultrasonic humidifier that emits micronized water particles into the room by ultrasonic vibration of the stored water, and a combined humidifier that simultaneously includes a heating humidification system and an ultrasonic humidification system.

In recent years, water adhering to the surface of the disk is blown by blowing water that has moved to the upper side of the humidifying filter after immersing the humidifying filter in the water tank, or by rotating a part of a plurality of disks immersed in the water tank (Air blowing type) humidifier which uses a vaporizing method is also used.

Generally, in the case of a natural humidifier, air sucked by a blowing fan is atomized while passing through a humidifying filter by sucking outside air by the blowing fan. The atomized air is discharged to the outside through the outlet of the humidifier to humidify the dry room.

In the case of a humidifying device of a natural type, the humidifying device has various structures, though it has a stand-type structure in that it has a structure for accommodating water for the function of the humidifying device.

In such an automatic mode, the humidity sensor provided in the humidifying device may be provided with a humidifying device for humidifying the humidifying space, After the humidity is determined, the humidification amount is adjusted.

However, as shown in FIGS. 1 and 2, the amount of humidification is determined by the amount of water held in the air generated by the fan 10. Therefore, in order to increase the humidification amount, the motor rotation speed of the fan 10 increases Thus, when the rotational speed of the motor increases, the speed of the air coming out of the humidifier 1 is increased, and the air blows away from the humidifier to raise the humidity at a distance from the humidifier 1.

In the case where the humidification amount is increased, the humidified portion is a long distance from the humidifier 1, and in order for the humidity sensor 11 mounted on the humidifier 1 to sense the humidifying effect, It takes a long time to reach the humidification device 1 again.

3A and 3B, it is determined that the humidity is initially low and air containing moisture is supplied to the humidifying region III. In the case of the region II and the region I, moisture is only supplied through the humidifying region III There is no direct reaction, but an indirect reaction.

Therefore, in the automatic mode, even when the humidification space is sufficiently humidified, the humidification amount can not be detected. Therefore, it is determined that a large amount of humidification is required, so that the motor rotational speed is rapidly driven. As a result, not only waste of energy but also noise is generated.

In addition, in recent years, additional functions such as anion generation have been added to the humidifying device 1. In some of the additional functions, when the time elapses, the effectiveness of the humidifying device 1 deteriorates, There is a problem that only the space directly supplied by the apparatus enjoys the effect of the additional function.

Particularly, there is a problem in that, when the additional function is operated in the automatic mode, the region in which the effect of the additional function can be enjoyed varies depending on the amount of the humidification.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a humidification control method that enables accurate humidity measurement in a humidification device including a humidity sensor and automatically controlling the humidification amount.

In addition, the present invention aims at driving the humidifier while changing the rotational speed of the motor in a predetermined range, thereby reducing the generation of noise and reducing the energy entering the humidifier.

Another object of the present invention is to make it possible to enjoy the effect of the additional function evenly in the humidifying region in the humidifier having the additional function.

It is another object of the present invention to provide a humidification control method capable of performing booster humidification so as to prevent a shortage of an absolute humidification amount due to driving while varying at a motor rotational speed within a predetermined range.

In order to achieve the above object, the present invention provides a humidification control method as described below.

The present invention relates to a method for controlling the humidification of a humidifying apparatus for discharging moisture into the flow of air generated by a fan, the method comprising the steps of: acquiring humidity information of a humidifying space through a humidity sensor provided in the humidifying apparatus; And a fan control step of repeatedly driving a motor rotational speed of the fan in a predetermined pattern varying in a constant speed range on the basis of the acquired humidity information so as to supply moisture, The rotational speed is repeatedly varied in a plurality of steps in the predetermined speed range so as to directly supply moisture to the entire area of the humidifying space, and the larger the difference between the obtained humidity information and the target humidity, The drive time of the minimum value of the constant speed range is reduced, The time for driving the motor rotation speed to the maximum value of the constant speed range is increased by the decrease of the drive time of the minimum value of the constant speed range and the average value of the motor rotation speed is increased in the repeated pattern of the motor rotation speed Thereby providing a humidification control method for driving the motor.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

 1, a humidifier 1 according to the present invention includes a fan 10, a motor for driving the fan 10, and a humidity sensor 11 for measuring the humidity around the humidifier. In the present invention, if humidification is included in the flow of the air generated by the fan 10, the humidifying method may be any method such as an ultrasonic method, a heating method, or a natural method. However, It may be preferable to use a natural method which does not require any separate means.

In the present invention, the humidity information obtained from the humidity sensor 11 for detecting the humidity around the humidifier 1 is set in comparison with the target humidity to set the humidification amount. At this time, in the present invention, the fan motor rotational speed is not set to a single value according to the amount of humidification, and the motor rotational speed of the fan 10 is repeatedly varied in a predetermined pattern in a constant speed range.

As shown in FIGS. 4A to 4C, the fan can be controlled so as to have a pattern in which the rotational speed of the motor is alternately changed in the fan speed adjusting step of the humidifier, for example, in the middle, middle, and the middle.

4A shows a pattern graph when the difference between the humidity sensor and the target humidity measured in the humidifier is about halfway. Here, the term "medium" refers to a situation in which an average amount of humidification corresponding to the motor speed of the middle is required.

As shown in FIG. 4A, the motor is operated at the rotational speed corresponding to 'steel' from t1 to t2, the motor is operated at the rotational speed corresponding to 'middle' at t2 to t3, The motor is operated at a rotational speed corresponding to 'middle' at t4 to t5 at the corresponding rotational speed, and the motor can be controlled to operate in the same pattern as t1 to t5 at t5 to t9.

As described above, in the present invention, the humidification amount itself is the same as when the motor is continuously operated at the rotational speed corresponding to 'middle', but the rotational speed corresponding to 'weak' and the rotational speed corresponding to ' And operates while varying the rotational speed. Thereby, the supply region of the water discharged from the humidifier can be evenly supplied to the regions I to III (see Figs. 3A and 3B).

4B and 4C show a pattern graph when the difference between the humidity sensor measured by the humidifier and the target humidity is medium or higher.

The pattern of FIG. 4B is repeated t1 to t8, and all of the steps of 'strong', 'middle' and 'weak' are performed in the same manner as in FIG. 4A, but 'strong' and 'middle' are operated three times at t1 to t8 However, 'drug' works only once, raising the overall humidification amount itself. That is, a pattern having a large proportion of 'steel' in the pattern is shown.

4C, the pattern itself is the same as that of FIG. 4A, but it is possible to increase the time in each step, that is, increase the time in 'strong', and decrease the time in 'weak'.

By changing the pattern in such a manner or changing the time of the step, it is possible to increase the overall humidification amount. In this case, the "weak" step is also included to allow moisture to be supplied throughout the humidifying space.

In the graph, the lower area is proportional to the humidification amount, so the humidification amount can be adjusted by adjusting the overall average motor rotation speed. However, in any case, the fluctuation is made within a predetermined range, so that the moisture contained in the flow of air generated by the fan is provided in various regions.

In addition, even when the rotational speed of the motor requires a large amount of humidification amount, it is not operated only at the maximum speed, which not only reduces the noise due to the rotation of the motor in the automatic mode, but also prevents waste of energy.

Particularly, by providing humidification to an even area (areas I, II, and III (see Figs. 3A and 3B), the humidity sensor 11 of the humidifying device 1 helps to grasp accurate humidity, It is possible to reduce the power supplied to the fan, which is operated to supply unnecessarily excessive moisture, thereby preventing wasted energy.

On the other hand, when a small amount of humidification is required, the motor can be operated in a pattern including all stages of 'strong', 'medium', and 'weak' while the average humidification amount is being increased. 4c, that is, increasing the number of 'weak' or increasing the 'weak' time.

FIG. 5A shows a flowchart of a method of controlling the humidification in the present invention.

The automatic mode starts, and the humidifier 1 acquires the humidity information of the humidification space from the humidity sensor 11 (S100). The humidity information thus obtained is used to operate the fan motor 10 of the humidifier 1 while repeating the pattern after selecting any one of the patterns having mutually different humidification amounts based on the target humidity or the humidity information itself (S101).

At this time, it is preferable that the pattern is configured to vary in a constant speed range so as to supply moisture to the humidification space as a whole. Further, although the motor speed may be a pattern in which the motor speed is continuously deformed, it is preferable that the multistage motor speed is changed stepwise when the humidifier 1 is operated in the manual mode.

After the predetermined time has elapsed after the pattern is determined, the humidity information for the humidifying space is acquired again from the humidity sensor 11 and compared with the humidity information measured from the humidity sensor 11 at the beginning, (Step S102).

If it is determined that the humidity has changed (S102), if it is determined that the humidity has changed, the humidification is continued with the previous pattern (S103). At this time, it is needless to say that after the humidity information is further obtained from the humidity sensor 11, the humidification can be continued in accordance with the changed pattern.

On the other hand, if it is determined that the humidity has not changed at the time of determining whether the humidity has changed (S101), the booster mode for promoting humidification may be entered.

The booster mode is entered and the timer is activated (S110). After the timer is activated, the motor is operated by modifying the pattern set in the step S101. If the time t of the timer is less than the preset time t0, the motor is operated in a modified pattern (S111). If the time t of the timer is less than the preset time t0, (t) is equal to or larger than the set time t0, the timer is set to the fixed value (S113), and the corrected pattern is returned to the original pattern (S103).

Fig. 5B shows an example of a method of correcting the pattern.

FIG. 5B shows a modified pattern when the pattern (S102) determined by the humidity measurement is the pattern of FIG. 4A and there is no humidity change for a predetermined time (S102). The solid line is the pattern before modification (the same as the pattern in Fig. 4A), and the dotted line is the pattern after modification.

As shown in Fig. 5B, in the case of no humidity change, the pattern is modified in such a manner as to raise the humidification amount in order to promote the humidity change. In the case of FIG. 5B, it is exemplified that the time of 'strong' is increased. However, it is also possible to modify the pattern itself into a pattern having a larger amount of moisture than the pattern determined in step S101. For example, it is possible to modify the pattern of FIG. 4A to the pattern of FIG. 4B, and if necessary, it is also possible to drive continuously with only 'steel'.

As such, modifying the pattern can be performed in a variety of ways if it increases the overall humidification amount, i.e., increases the area of the graph.

However, in the case of such a booster mode, since the amount of humidification is increased in step S101, it is performed only for a predetermined time, for example, about 1 to 3 minutes. If the predetermined time has passed, (S103). ≪ / RTI >

In the case of the booster mode, since the speed of the motor is increased in order to supply the water amount larger than the required water amount, the energy and the noise to be used are accordingly increased, so that continuous use of the booster mode may waste energy , And is preferably automatically stopped after a predetermined time is used.

6A to 6C show a graph of the motor speed pattern in the automatic mode at night. Each of Figs. 6A, 6B and 6C corresponds to Figs. 4A, 4B, and 4C, and the graph of the motor speed pattern at night is shown by solid lines and the graph of the motor speed pattern during the day is shown by dotted lines.

In the case of the nighttime, since the user is sensitive to noise since it is a time for the user to relax, the motor is driven by lowering the 'strength' of the pattern determined by the humidity information measured by the humidity sensor 11 to 'middle'. By doing so, it is possible to utilize both the nighttime and the daytime by modifying one pattern without separately specifying the daytime and nighttime patterns.

The nighttime determination may be made by a method in which the humidity sensor 1 is provided with a light intensity sensor (not shown) so as to determine the nighttime by the measured value in the illuminance sensor, or by the user's input.

Even in the night mode or the booster mode, the present invention repeatedly operates while changing the motor speed in a predetermined range, thereby achieving uniform humidification, noise, and energy saving of the entire humidification region.

Particularly, in the case of a humidifying device including an additional function such as anion, the additional function can be dispersed evenly throughout the humidifying region together with moisture, and thus the additional function can be maximized.
