Description

{Natural Evaporation Type Humidifier}

The present invention relates to a humidifier which humidifies by a natural evaporation method without consuming energy such as electric power.

Electric humidifiers are widely used to increase indoor humidity in a dry indoor environment. Conventional electric humidifiers generate water vapor in a manner that most of them use an ultrasonic method or boiling water. Such an electric humidifier has to be cleaned regularly due to contamination or propagation of bacteria due to long-term use. It is difficult to clean the inside of a water bottle or every corner of the water flow channel. In addition, the electric humidifier consumes a small amount of electric power but consumes energy and generates noise during operation, thereby interfering with a good night's sleep.

Patent Literature 1 (Laid-Open Utility Model Application No. 20-2011-0005315) discloses a technique in which a plurality of towels are vertically suspended and the lower portion of the towel is submerged in the water contained in the lower water bottle, And a towel humidifier in which water is evaporated naturally. However, in this type of natural humidifier, the amount of water drawn to the towel by the capillary phenomenon is insignificant, and the substantial humidifying effect is insignificant (as shown in the following experimental example, the amount of water evaporated by this method, little).

On the other hand, the present applicant has proposed a laundry drying type humidifier as shown in Fig. 1 through Patent Document 2 (Japanese Patent Application Laid-Open No. 10-2007-0055458). In order to overcome the limitation of the system of Patent Document 1 in which the water for evaporation is supplied only from the lower water tank to the upper water tank only by the capillary phenomenon, the humidifier shown in Patent Document 2 is stretched as shown in Fig. A water supply bucket is installed on the upper part of the washing machine for humidification (kitchen towel), and one end of the water supply laundry (wick) is immersed in the water in the water supply bucket through one side of the water supply bucket, And the other end of the laundry for water supply is connected to a plurality of clothes for humidification while enclosing the outer side and bottom of the water supply water container. Accordingly, the water contained in the water supply bucket is absorbed by one end of the laundry for water supply, is pulled up to the upper end of the water supply bucket by the capillary phenomenon, and then is sucked down by the capillary phenomenon and gravity And is supplied much more smoothly than the above-described Patent Document 1. On the other hand, the storage bucket under the laundry for humidification is a bucket which is supplied to the laundry for humidification and then receives the water that continues to flow without being evaporated.

The humidifier of Patent Document 2 has a problem that the supply of water for evaporation is more smooth than that of the humidifier of the same type as in Patent Document 1, but it is difficult to adjust the supply amount (supply speed) of water per unit time. In the humidifier of Patent Document 2, the supply rate of the water for evaporation can be adjusted by adjusting the width of the portion located in the water supply bucket in the water supply laundry (core) and the angle formed by this portion to the horizontal plane. That is, the width of the laundry for water supply is made wider, and as the angle is decreased, the supply speed of water is increased. On the other hand, as the width is narrowed or the angle is increased, the supply speed of water is decreased. However, it is actually difficult to optimize the supply speed of water by adjusting the width and angle of the laundry for supplying water, so that all of the water contained in the water supply bucket is supplied within a few hours after exceeding the evaporation rate, The amount of water that has been reduced overnight (the amount of water contributing to the actual humidification) is often insignificant, because it is not evaporated and becomes solid in the storage bucket or, conversely, the water supply rate is too slow. Particularly, the washing water for supplying water is not easy to control the angle, and even if it is adjusted, the angle is changed with time, and the supply speed of water is changed.

On the other hand, Patent Document 3 (Japanese Patent Application Laid-Open No. 10-1172249) and Patent Document 4 (Japanese Patent Application Laid-Open No. 10-2011-0018622) use a method of supplying water from an upper portion of an evaporated cloth or a towel Discloses a natural evaporative humidifier using a flow rate control valve (Patent Document 3) or a flow rate adjusting device of a ringer hose as a mechanism for controlling the supply speed of water. However, the present inventor has experienced many times that such a flow rate control valve or a viscosity regulator can not function properly due to a small amount of water due to minerals or impurities contained in the water. Of course, these flow control valves or scoop adjusters can be cleaned and pierced when they are clogged, but they are cleaned and punctured by ordinary users because of the slow rate of water supply and the small rate of impact Is practically impossible. In addition, it is not practical to use ultrapure water (distilled water) that does not contain impurities or minerals as humidifying water.

Patent Document 1: Published Utility Model Publication No. 20-2011-0005315 Patent Document 2: JP-A-10-2007-0055458 Patent Document 3: JP-A-10-1172249 Patent Document 4: Japanese Patent Application Laid-Open No. 10-2011-0018622

FIG. 2 is a perspective view showing a schematic structure of a humidifier according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view thereof.

2 and 3, the humidifier according to the present embodiment includes a frame 10, an upper water bottle 20, a water relay unit 40, an evaporator unit 30, and a lower water bottle 50 do.

The frame 10 is a constituent element that maintains the shape of the entire humidifier and supports the upper water bottle 20, the water relay unit 40, the evaporator unit 30, and the lower water bottle 50 as the remaining components. The frame 10 may be manufactured by connecting / assembling / adhering a plurality of metal rods, pipes, beams or plate materials by means of welding, bolts, rivets or adhesives or by bonding a plurality of plastic rods, pipes, They can be formed by assembling them and assembling them or connecting / attaching them using connectors or adhesives.

In the present embodiment, the frame 10 is composed of a total of four letter-shaped beams 11 arranged vertically and a total of twelve letter-shaped beams 12a through 12d arranged horizontally, And is divided into an upper portion, a middle portion and a lower portion by the L-shaped beams 12b and 12c disposed laterally in the lower middle portion. It goes without saying that the overall shape of the frame 10, the shape and the number of the components, and the like can be modified as desired.

The upper water column 20 and the water relay unit 40 are mounted on the upper part of the frame which is defined by the upper transversely arranged rectangular beams 12a and the upper middle rectangular beams 12b, The evaporator unit 30 is mounted on the middle portion of the frame and the evaporator unit 30 is mounted on the lower portion of the frame so that the upper end of the evaporator unit 30 Side end portions of the lower mounting table 32 and the lower water basin 50 are disposed.

The upper water tank 20 stores water to be supplied for humidification, and a hole 21 having a diameter of 1 to 7 mm is drilled in the center of the bottom surface of the upper water tank 20 (the diameter and the action of the hole will be described later ). The upper water bottle 20 is made of plastic, for example, and a commercially available product of a suitable standard may be used. The upper water bottle 20 has a protrusion 22 protruding sideways at the upper end of the upper water bottle 20 so as to be hooked on the upper surface of the angled beams 12a disposed horizontally at the upper end of the frame 10. However, It is not necessary that the projection 22 of the upper water bottle 20 is caught on the upper end of the frame 10 in an actual use state as described later.

The evaporator unit 30 is mounted on the frame 10 so as to be spaced apart from the upper water bottle 20 via the water relay unit 40 at the lower part of the upper water bottle 20 and is connected to the water relay unit 40 through the water relay unit 40 And receives the water supplied from the upper water bottle 20 to evaporate while flowing downward.

In the present embodiment, the evaporator unit 30 includes an upper holder 31, a lower holder 32, and a plurality of evaporator 33.

The upper holder 31 and the lower holder 32 have substantially the same basic structure and can be manufactured by combining / assembling / shaping a rod, pipe, beam or plate made of metal or plastic, like the frame 10 . As shown in Fig. 4, the upper holder 31 and the lower holder 32 are respectively provided with a plurality of mounting portions 31a and 32a arranged parallel to each other and a pair of mounting portions 31a and 32a And connecting portions 31b and 32b for connecting the connecting portions 31b and 32b to each other. At this time, the outer side end of the mounting part located at the outermost part of at least the upper mounting table 31 of the plurality of mounting parts 31a, 32a is bent perpendicularly to the plane formed by the mounting tables 31, 32, . This is to prevent deformation such as bowing of the upper mounting table 31 due to the load when the upper water bottle 20 is placed on the upper mounting table 31 via the water relay unit 40 which will be described later.

In the present embodiment, the upper holder base 31 and the lower holder base 32 are manufactured by laminating a flat plate material by a method such as punching or laser cutting. The mounting portions 31a and 32a and the connecting portions 31b and 32b of the upper mounting base 31 and the lower mounting base 32 are each formed of a flat plate and are connected to both ends of the mounting portions 31a and 32a, , 32b can be manufactured in the shape of a ladder by being connected by rivet, welding, adhesive or the like. The distance between the mounting portions 31a and 32a adjacent to the width of the mounting portions 31a and 32a is set to be 0.5 to 4 in order to prevent the evaporation bins 33, cm.

The mounting portions 31a and 32a of the upper and lower mounting bases 32 correspond to each other and are paired with each other. Each of the mounting portions 31a and 32a is provided with one evaporator 33 in the form of a loop, And the evaporation bubbles 33, which are drawn as many as the number of the openings 31a, 32a, are engaged. The evaporation foil 33 is made of a woven fabric, a nonwoven fabric, or a paper made of natural or synthetic fibers having good water absorption and evaporation efficiency, and a commercially available product such as a kitchen towel or a cleaning nonwoven fabric can be used.

The evaporator unit 30 composed of the upper holder 31, the lower holder 32 and the plurality of evaporator 33 is mounted on the frame 10, and specifically, the evaporator unit 30, End connecting portion 31b of the evaporator unit 30 is placed on the upper surface of the upper half-sided beams 12b of the frame 10 and the both-end connecting portion 32b of the lower mounting table 32 of the evaporator unit 30 is fitted Shaped beams 12c in the middle of the lower side of the base 10 in Fig.

On the other hand, the evaporator unit 30 can be detachably mounted on the frame 10. For this purpose, as shown in FIG. 2 and FIG. 3, for example, the height of the upper half of the upper half-pillar beams 12b and the height of the upper half of the upper half- End connection portion 31b of the upper mount table 31 and the lower mount table 32b of the upper mount table 31 are formed in the cutout grooves 11a and 11b at the height immediately below the lower surface of the L- End connecting portion 32b of the connecting portion 32a and the connecting portion 32b.

The evaporator 21 can be attached to or detached from the frame 10 so that the evaporator 21 can be separated from the frame 10 by using a humidifier for a long period of time The evaporation unit 30 can be detached from the frame 10 to replace only the evaporation can 33 and mount the evaporation unit 30 on the frame 10 again.

In the case where the mounting portion 31a of the upper mounting table 31 is made of a thin plate material as described above, the upper mounting table 31 of the evaporator unit 30 is provided with an upper water tank 20 and a water Depending on the weight of the relay unit 40, the intermediate portion on which the water relay unit 40 is placed may be downward. Then, the portion of the evaporator 33 positioned below the middle portion may not be straightened downward, but may be bent, and the adjacent evaporator 33 may adhere to each other, thereby lowering the evaporation efficiency. In order to solve this disadvantage, it is preferable that at least the outermost mounting portion 31a of the upper mounting table 31 is made of a Lamb-shaped beam so as to have rigidity.

Next, the water relay unit 40, which is the most important component for determining the supply speed of water together with the hole 21 of the upper water bottle 20 in the humidifier according to the present invention, will be described with reference to FIGS. 2 to 5. FIG. FIG. 5 is a partial cross-sectional view of the humidifier shown in FIG. 2, showing the upper water bottle 20 and the upper end of the evaporator unit 30 with the water relay unit 40 as a center.

The water relay unit 40 is installed to be positioned between the upper water bottle 20 and the evaporator unit 30 so that the water discharged from the hole 21 of the upper water bottle 20 is supplied to a plurality of And distributes the same evenly to the evaporator 33 and relays it.

As described above, in the case of the humidifier disclosed in Patent Document 2, it is difficult and uneven to adjust the supply rate of water, while the humidifier disclosed in Patent Documents 3 and 4 can control the supply speed of water finely, but the flow rate control valve, And it is difficult to perform maintenance such as cleaning.

The inventor of the present invention has found that the diameter of the hole 21 is adjusted by the flow regulator of Patent Documents 3 and 4 by supplying the water from the upper part of the evaporator 33 through the hole 21 in the bottom of the upper water bottle 20 (For example, several millimeters) larger than the diameter of the flow path, the user can easily clean the hole 21 even if the hole 21 is not clogged easily. However, if the diameter of the hole 21 is simply increased, the water is discharged at a rate much faster than the evaporation rate of the evaporation can 33 through the large hole, and there is almost no humidification effect (as will be described later) The water flowing down along the evaporator 33 without being vaporized can be stored in the lower water bottle 50. However, the water remaining in the lower water bottle 50 and the water in the lower water bottle 50 can be returned to the evaporator 33 The degree to which the raised water evaporates and contributes to humidification is negligible).

Therefore, in the present invention, even if the diameter of the hole 21 of the upper water bottle 20 is increased, the water relay unit 40 is designed so that water is not discharged quickly through the large hole 21. That is, in the humidifier according to the present invention, the water relay unit 40 is configured such that the upper end of the water relay unit 40 contacts the bottom surface of the upper water bottle 20 while completely blocking the hole 21 of the upper water bottle 20, And at least the surface is made of a material having absorbency. In other words, at least the surface of the water relay unit 40 is made of an absorbent material so that the water discharged through the holes 21 can flow out along the surface of the water relay unit 40 in a small amount. The upper end of the water relay unit 40 is also pressurized by the weight of the water stored in the upper water bottle 20 and the upper water bottle to block the hole 21 with an appropriate pressure. The lower end of the water relay unit 40 is in contact with the upper end of a plurality of evaporator 33 hanging on the upper holder 31. The lower end of the water relay unit 40 is discharged through the hole 21 and passed through the surface of the water relay unit 40 So that the water flowing through the evaporator 33 is evaporated.

On the other hand, if the water in the upper water bottle 20 is reduced as time elapses, the water pressure of the water discharged through the holes 21 is also reduced, and if the upper end of the water relay unit 40 has a constant closing force of the holes 21 There is a possibility that the supply speed of water decreases with time. However, since the water relay unit 40 of the present invention is structured so as to be pressed by the weight of the water stored in the upper water bottle 20 and the upper water bottle, when the water in the upper water bottle 20 is reduced, The pressure applied to the upper end of the hole 21 and the pressure applied to the upper end of the hole 21 and the hole 21 is reduced, thereby canceling the lowering of the hydraulic pressure and the lowering of the supply speed with the lapse of time, (Supply speed) of the water discharged through the pipe can be kept constant. In view of this, as described above, the projections 22 projecting sideways from the upper outer peripheral portion of the upper water bottle 20 are prevented from being caught by the upper surface of the L-shaped beams 12a arranged laterally at the upper end of the frame 10 . That is, it is preferable that the upper water bottle 20 can naturally pressurize the water relay unit 40 according to the weight of the upper water bottle 20 and the water stored therein.

In the present embodiment, the water relay unit 40 is composed of a relay block 41, a relay plate 43, and relay cloths 42 and 44 surrounding them.

The relay block 41 is a component disposed directly below the hole 21 of the upper water bottle 20 and blocking the hole 21. The relay block 41 may be made of a material such as a sponge, at least the surface of which is absorbent so as not to completely block the hole 21, as described above. Alternatively, as in the present embodiment, the relay block 41 itself is made of a light material such as styrofoam which does not have absorbency, and the outer surface of the relay block 41 is made up of a relay cloth (first relay cloth 42) As shown in FIG. As the first relay fabric 42, a woven fabric, a nonwoven fabric, paper or the like having the same material as that of the evaporator 33 may be used.

5, the upper surface of the relay block 41 is provided with a recessed groove (not shown) having a diameter larger than the diameter of the hole 21 at a position corresponding to the hole 21 of the upper water bottle 20 41a are formed. This groove 41a is not essential but is an auxiliary means for regulating the force of closing the hole 21 by the relay block 41 and thus the supply speed of water. That is, even if there is no groove 41a, the hole 21 can be closed with an appropriate pressure by the relay block 41 and the first relay cloth 42 wrapped around the groove 41a. However, The first relay cloth 42 located at the upper portion of the relay block 41 is pressed by the first block 41 to lower the water absorbency and consequently block the hole 21 with excess pressure (consequently, the water supply speed is lowered) So as to provide a constant pressing force and function to temporarily store the water discharged through the holes 21. [0031] As shown in FIG.

The relay plate 43 is disposed below the relay block 41 and accommodates the relay block 41 wrapped around the first relay can 42 so that the lower end of the relay block 41 is placed in contact with the upper end of the plurality of evaporator 33 In the form of a plate or tray. The relay plate 43 has a function of buffering the increase and decrease of the water supply speed by temporarily storing the water flowing through the first relay cloth 42 which is discharged through the hole 21 and wrapped around the outer surface of the relay block 41 And functions to diffuse the supplied water evenly throughout the plurality of evaporation bubbles 33. To this end, the relay plate 43 is wrapped with a relay cloth (second relay cloth 44) whose outer surface is absorbent. As the second relay fabric 44, a woven fabric, a nonwoven fabric, paper, or the like having the same material as that of the evaporator 33 may be used. The relay plate 43 is set so that at least the length of the relay plate 43 in the Y axis direction is equal to or longer than the length in the Y axis direction of the upper holder base 31 so that water can be diffused throughout the plurality of evaporator bosses 33. [ do.

On the other hand, if the water supply rate is kept constant by the relay block 41 and water can be evenly diffused throughout the plurality of evaporation bubbles 33, the relay plate 43 may be omitted. In this case, the length of the relay block 41 in the Y-axis direction should be set to be greater than or equal to the Y-axis length of the upper holder 31.

On the other hand, the hole 21 of the upper water bottle 20 can be made relatively large by the structure of the water relay unit 40 as described above. However, the diameter of the hole 21 is excessively large or excessively small Is not desirable. If the diameter of the hole 21 is excessively large, the discharge speed (supply speed) of the water through the hole 21 may become excessively large even if the water relay unit 40 pressurizes and blocks. Conversely, if the diameter of the hole 21 is excessively small, the water discharge speed may not be excessively dropped or discharged due to the cohesive force of the water and the pressing force of the water relay unit 40, It may be blocked. Therefore, in consideration of this point, the diameter of the hole 21 is preferably 1 to 7 mm, more preferably 3 to 5 mm. However, the diameter of the hole 21 may be changed depending on the overall size or capacity of the humidifier.

In this embodiment, the hole 21 is shown as being pierced in the center of the upper water bottle 20. However, when the size of the humidifier, that is, the upper water bottle 20 is large, a plurality of holes can be drilled. The diameter of the hole 21 can be appropriately reduced in accordance with the number of holes.

The diameter and the number of the holes 21 formed in the bottom surface of the upper water bottle 20 play an important role in adjusting the supply speed of the water. It is preferable that the water supply speed can be easily adjusted by adjusting the diameter and the number of the water.

To this end, it is possible to drill a plurality of holes having the same or different diameters on the underside of the upper water bottle 20, and to selectively open or close the plurality of holes when using the humidifier. Concretely, a plurality of holes having various diameters are drilled on the bottom surface of the upper water bottle 20, and a combination capable of obtaining the optimum water supply speed through trial and error is selected. Then, . Or a plug made of, for example, rubber that fits each hole, so that the holes that do not belong to the optimal combination can be plugged with plugs.

The humidifier according to the present embodiment may further include a lower water bottle 50 disposed at a lower portion of the evaporator unit 30. The lower water bottle 50 is a water bottle that flows along the plurality of evaporation bubbles 33 to receive water that has not yet evaporated, and is an element for preventing water from flowing down to the bottom of the room without being evaporated. However, if the water flowing down along the plurality of evaporator (s) 33 is completely evaporated, or if some water flows on the floor of the room, the lower water bottle 50 may be omitted.

On the other hand, when the lower water bottle 50 is provided, the lower end portion 33a of the plurality of evaporator 33 may touch the bottom of the lower water bottle 50. This is because, after all the water in the upper water bottle 20 has been exhausted and the water evaporated in the evaporator 33 has evaporated, the water in the lower water bottle 50 is drawn up by the evaporator 33 to evaporate, This is to obtain a humidification effect.

Next, a humidifier according to an embodiment of the present invention will be described with reference to specific embodiments. It should be understood, however, that the detailed construction described in this embodiment is merely a preferred embodiment of the present invention, and does not represent all of the technical ideas of the present invention, so that various equivalents and modifications It should be understood.

8 pieces of the same nonwoven fabric as that of the first relay fabric 42 were cut to have a length of 1260 mm and a width of 260 mm to prepare an evaporator 33. The middle portion of each evaporator 33 was placed on the upper Hanging on each of the mounting portions 31a, and both ends of the evaporator 33 underneath the corresponding mounting portions 32a of the lower mounting table 32 are formed into a loop shape by snap-tightening with a snap button. The distance between the upper holder 31 and the lower holder 32 in the completed evaporator unit 30 was about 520 mm and the lower end of the evaporator 33 hanging below the mounting portion 32a of the lower holder 32 33a) was about 80 mm in length.

(5) Lower water bottle (50)

A transparent plastic bottle having a size of a width (X axis length) of 260 mm, a length (Y axis length) of 190 mm and a height (Z axis length) of 60 mm was used as a lower water bottle 50.

The constituent elements prepared as described above are assembled / combined to constitute a humidifier as shown in FIG. At this time, the projection 22 projecting sideways from the upper end of the upper water bottle 20 is located about 2 cm higher than the upper end of the frame 10.

An experiment was conducted to measure the humidifying effect on the humidifier manufactured as above. Experimental conditions were as follows: In a room maintained at a relative humidity of about 30% and a temperature of about 20 캜, about 1.6 L of tap water was supplied to the upper water bottle 20 in a state where all components of the humidifier including the evaporator 33 were dry. (The initial water level of the upper water bottle: 30 mm), the decreased amount of water (reduced water level) contained in the upper water bottle 20 as time elapses, the evaporated water is wetted downward from the upper end of the evaporator 33 by the supplied water And the amount of water (water level) to be accumulated in the lower water bottle 50 was measured. On the other hand, the humidifying effect is measured by measuring the amount of water (reduced water level) reduced in the upper water bottle 20 and the amount of water accumulated in the lower water bottle 50 with the lapse of time, It was evaluated by considering that a reduced amount of water evaporated and contributed to humidification.

After 5 minutes passed from the start of the experiment, all of the relay bags 42 and 44 wrapped around the relay block 41 and the relay dish 43 were wetted and the evaporation can 33 was not yet wetted. The relay cloth 44 wrapped around the relay dish 43 was kept wet until the end of the experiment (when the water in the upper water bottle 20 was exhausted), but the water was not accumulated in the relay dish 43 Respectively. Hereinafter, the results of measurement over time are summarized in the following table.

Elapsed time
(time) The level of the upper water bottle
(mm) Wetted length of evaporation gun
(cm) The level of the lower water bottle
(mm) 0.5 25 5 to 10 0 One 23 20-25 0 2 19 40 to 50 0 3 16 Total (however, the evaporation pellet at the outermost periphery does not increase further at about 40 cm) 0 4 12 0 5 7 0 6 One 0

As shown in Table 1, when about 6 hours have elapsed, almost all of the water in the upper water bottle 20 is exhausted and water is not accumulated in the lower water bottle 50 until the end of the experiment. It can be seen that the gas is evenly evaporated. This degree of evaporation and evaporation rate are sufficiently practical in view of the evaporation rate and evaporation rate of a conventional ultrasonic humidifier.

On the other hand, in Table 1, the wetted length of the evaporation bubbles was slightly wider, depending on the location of the evaporation bubbles, particularly, the evaporation bubbles on the outermost side were less wetted, It is thought that the most evaporation occurred in the outermost evaporation chamber. At the time when the lapse of three hours or more, the evaporation bell 33 was sufficiently wetted to the lower evaporation bell end portion 33a that was hung down to the bottom of the lower water bell 50, but it did not float in the lower water bell 50. It can be seen from this that the rate of evaporation of water by the evaporator 33 and the rate of supply of water to the evaporator 33 are almost the same.

Here, when the average supply rate of water is calculated, it is 1600 ml ÷ 360 minutes ≒ 4.44 ml / minute ≒ 0.074 ml / second, assuming that 1.6 L of water is constantly supplied over 6 hours. It is difficult to control.

Next, as a comparative example, in order to confirm the humidifying efficiency in the same manner as in Patent Document 1 in which water is supplied from the lower part to the upper part by the capillary phenomenon, the humidifier according to the embodiment of the present invention is used under the same conditions, 20), the same amount (1.6 L) of tap water was contained only in the lower water bottle 50 without supplying water, and the amount of water decreased with the passage of time was measured. As a result, the evaporation rate (the rate at which the water is reduced) of the water is remarkably decreased to such an extent that it is difficult to accurately measure (the water level of the reduced water is about 20 mm at the passage of 14 hours, 1 and the natural evaporative humidifier of the same type were not practical.

As described above, according to the humidifier of the present invention, water can be supplied to the evaporator at a proper and constant rate according to the evaporation rate of water, and a humidifier which is practical enough without using any additional energy such as electric power can be provided. The humidifier of the present invention can be used only by arranging the water relay unit 40 in accordance with the hole 21 of the upper water bottle 20 and filling the upper water bottle 20 with water, And the hole 21 of the upper water bottle 20 is not so small as to be easily clogged so that even a general user can use the water bottle for a long time without any problem.

And various modifications and variations are possible within the scope of the appended claims.
