Description

Natural Evaporation Humidifier

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

Electric humidifiers are widely used to increase indoor humidity in dry indoor environments. Most conventional electric humidifiers generate steam by ultrasonic method or heating by boiling water. Such an electric humidifier has to be cleaned periodically because of contamination or bacteria propagation due to long-term use, but it is difficult to clean the inside of the bucket or every corner of the flow path. In addition, the electric humidifier consumes less energy, but there is a problem of disturbing a good night's sleep due to noise generated during operation.

Patent document 1 (Publication Utility Model Publication No. 20-2011-0005315) hangs a plurality of towels vertically and submerges the lower part of the towel in the water contained in the lower bucket. Towel humidifiers are disclosed that allow them to evaporate up naturally to evaporate. However, in this type of natural humidifier, the amount of water drawn up to the towel by capillary action is insignificant, and the actual humidifying effect is insignificant (as shown in the experimental example below), the amount of water that is evaporated by this method and contributes to the humidification is extremely small. little).

On the other hand, the applicant has proposed a laundry-drying humidifier as shown in Figure 1, through Patent Document 2 (Patent Publication No. 10-2007-0055458). The humidifier shown in Patent Literature 2 is lined up as shown in FIG. 1 to overcome the limitation of Patent Literature 1, which supplies only water for evaporation from the lower bucket to the upper towel only by capillary action. A water supply bucket is installed on the upper side of the plurality of humidifying clothes (kitchen towels), 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, The other end of the water supply laundry wraps the outer side and bottom of the water supply bucket and is connected to a plurality of humidifying clothes. Accordingly, the water contained in the water supply bucket is absorbed by one end of the water supply laundry and is pulled up by the capillary phenomenon to the top of the water supply bucket, and then the lowered humidification laundry under the capillary phenomenon and gravity. It is supplied to, and is supplied much more smoothly than the above-mentioned patent document 1. On the other hand, the storage bucket under the humidification laundry is a bucket receiving water that continues to flow without being evaporated after being supplied to the humidification laundry.

The humidifier of Patent Literature 2 has a problem in that water for evaporation is more smoothly supplied than a humidifier in the same manner as Patent Literature 1, but it is not easy to adjust the supply amount (supply rate) of water per unit time. The supply speed of the water for evaporation in the humidifier of patent document 2 can be adjusted by adjusting the width | variety of the part located in the water supply bucket by the water supply laundry (wick), and the angle which this part forms with a horizontal plane. That is, as the width of the water supply laundry is wider and the angle is smaller, the water supply speed is increased. On the contrary, the narrower the width or the larger the angle is, the lower the water supply speed is. However, it is not really easy to optimize the water supply rate by adjusting the width or angle of the water supply laundry, so that all of the water contained in the water supply bucket is supplied in one to two hours in excess of the evaporation rate. The water does not evaporate and accumulates in the storage bucket, or, on the contrary, the water supply rate is too slow so that only the upper part of the humidification laundry is wet and the amount of water (e.g., the amount of water contributing to the actual humidification) that is evaporated and reduced overnight is insignificant. In particular, the laundry for water supply is mushy and it is not easy to adjust the angle, even if adjusted, the angle is changed over time and the supply speed of the water is changed.

On the other hand, Patent Document 3 (Registration Patent Publication No. 10-1172249) and Patent Document 4 (Publication Publication Publication No. 10-2011-0018622) use a method of supplying water from the top of the lined evaporation cloth or towel. In addition, as a mechanism for adjusting the supply speed of water, a natural evaporative humidifier using a flow rate regulating valve (Patent Document 3) or a drop amount regulator of a Ringer hose is disclosed. However, the present inventors have experienced many times that such a flow control valve or a drop amount regulator does not function properly because the scale is easily clogged by the mineral component or impurities contained in the water. Of course, when the flow control valve or the drip regulator is clogged, it can be cleaned and drilled, but it is not easy to clean, and in view of the very slow water supply speed, even small damage affects the supply speed so that the general user cleans and drills it. It is practically impossible. In addition, it is also not practical to use ultrapure water (distilled water) free of impurities, minerals, and the like as humidifying water.

Patent Document 1: Publication Utility Model Publication No. 20-2011-0005315 Patent Document 2: Publication No. 10-2007-0055458 Patent Document 3: Registered Patent Publication No. 10-1172249 Patent Document 4: Publication No. 10-2011-0018622

As described above, a natural evaporative humidifier that does not use extra energy has been conventionally proposed, but the humidification effect is insignificant, it is difficult to control the supply rate (flow rate) of water for evaporation, or the cleaning or maintenance is difficult.

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

The frame 10 is a component that maintains the shape of the entire humidifier and supports the remaining components of the upper bucket 20, the water relay unit 40, the evaporator unit 30, and the lower bucket 50. The frame 10 is manufactured by connecting / assembling / gluing a plurality of metal rods, pipes, beams, or plates by means of welding, bolts, rivets, adhesives, or the like. It can be produced by molding into a joining form and assembling them or connecting / gluing them using connectors or adhesives.

In the present embodiment, the frame 10 is composed of a total of four L-shaped beams 11 arranged vertically, and a total of 12 L-shaped beams 12a-12d arranged horizontally, and the upper middle of the frame 10 and The upper, middle and lower portions are partitioned by the L-shaped beams 12b and 12c disposed horizontally in the lower middle. Here, of course, the overall shape of the frame 10, the shape and the number of each component, etc. can be modified as much as possible.

The upper bucket 20 and the water relay unit 40 are mounted on the upper part of the frame partitioned by the horizontally arranged beam-shaped beams 12a at the top and the beam-shaped beams 12b at the upper middle, and the beam-shaped beams at the upper middle. Both ends of the upper cradle 31 of the evaporation cloth unit 30, which will be described later, are mounted on the upper surface of the 12b, and the evaporation cloth unit 30 is mounted in the middle of the frame, and the evaporation cloth unit 30 is located below the frame. Both ends of the lower cradle 32 and the lower bucket 50 is disposed.

The upper bucket 20 stores water 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 bucket 20 (the diameter and the action of the hole will be described later. ). The upper bucket 20 is made of, for example, plastic and may be a commercially available product of a suitable standard. The upper outer circumference of the upper bucket 20 has a protrusion 22 protruding laterally so that it can be caught on the upper surface of the L-shaped beams (12a) arranged horizontally on the upper end of the frame 10, but not necessarily It is not necessary, and as will be described later, the protrusion 22 of the upper bucket 20 is not caught on the upper end of the frame 10 in the actual use state.

The evaporation bubble unit 30 is mounted to the frame 10 to be spaced apart from the upper bucket 20 through the water relay unit 40 at the lower portion of the upper bucket 20, and through the water relay unit 40. It is a component to receive the water supplied from the upper bucket 20 to flow down and evaporate.

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

The upper cradle 31 and the lower cradle 32 has substantially the same basic structure, and like the frame 10 described above, metal / plastic rods, pipes, beams or plates may be combined / assembled / molded to be manufactured. Can be. As shown in FIG. 4, the upper cradle 31 and the lower cradle 32 have a plurality of cradles 31a and 32a disposed in parallel with each other and both ends of the cradles 31a and 32a, respectively. It consists of a ladder-like form, including connecting portions 31b and 32b for connecting to each other. At this time, the outer side end of the mounting portion which is located at the outermost portion of the upper mounting bracket 31 of the plurality of mounting portions 31a, 32a is bent perpendicular to the plane formed by the mounting brackets 31, 32 so as to have a cross-shaped a-shaped mounting portion. It is preferable to form. This is to prevent deformation of the upper cradle 31 bent downward by the load when the upper bucket 20 is placed on the upper cradle 31 through the water relay unit 40 to be described later.

In the present embodiment, the upper cradle 31 and the lower cradle 32 are manufactured by processing a plate member on a flat plate in a ladder form by a punching process or laser cutting. Alternatively, the mounting portions 31a and 32a and the connecting portions 31b and 32b of the upper holder 31 and the lower holder 32 are each made of a flat plate, and both ends and the connecting portion 31b of the mounting portions 31a and 32a are respectively. , 32b) may be manufactured in the form of a ladder by being connected by riveting, welding, bonding, or the like. At this time, the interval between the width of the mounting portion (31a, 32a) and the adjacent mounting portion (31a, 32a), 0.5 ~ number in order to prevent the evaporation cloth 33 is lowered to stick to each other to lower the evaporation efficiency Set it to about cm.

In addition, the mounting portions 31a and 32a of the upper and lower mounting brackets 32 correspond to each other, and the pairs of the mounting portions 31a and 32a hang one evaporation cloth 33 in a loop form. The number of sagging evaporation cloths 33 is combined as many as 31a and 32a. The evaporation cloth 33 is made of a woven fabric, a nonwoven fabric, or paper made of natural or synthetic fibers having good water absorption and evaporation efficiency, and may use a commercial item such as a kitchen towel or a nonwoven fabric for cleaning.

In this way, the upper cradle 31, the lower cradle 32 and the evaporation cannon unit 30 composed of a plurality of evaporation can (33) is mounted on the frame 10, specifically, the upper cradle of the evaporator gun unit (30) The connecting portion 31b at both ends of the 31 is mounted on the upper surface of the L-shaped beams 12b in the middle of the upper side of the frame 10, and the connecting portions 32b at both ends of the lower cradle 32 of the vaporizing unit 30 are connected to the frame. It is mounted so as to be located under the L-shaped beams 12c in the lower middle of the 10.

Meanwhile, the evaporation cloth unit 30 may be detachably mounted to the frame 10. To this end, for example, as shown in Figs. 2 and 3, the height of the upper and lower middle just above the upper surface of the upper-shaped middle beams (12b) in the front of the vertically-shaped beam-shaped beam (11) The cutting grooves 11a and 11b are formed at the heights directly below the lower surfaces of the L-shaped beams 12c, respectively, and the connecting portions 31b and the lower holder 32 of the upper cradle 31 are formed in the cutting grooves 11a and 11b, respectively. It can be configured to be mounted by inserting both ends of the connecting portion (32b) of each) and pushed in the Y-axis direction.

In this way, the evaporation cloth unit 30 is formed in a form separate from the frame 10 and can be mounted / removed to the frame 10, so that the evaporation cloth 33 is used by using a humidifier for a long time (for example, one season). When damaged, such as being soiled or torn, the evaporation cloth unit 30 can be removed from the frame 10 to replace only the evaporation cloth 33 and can be mounted on the frame 10 again.

On the other hand, the upper cradle 31 of the evaporation cloth unit 30, especially as described above, when the mounting portion 31a of the upper cradle 31 is made of a thin plate, the upper bucket 20 and water mounted thereon By the weight of the relay unit 40, in particular the middle part on which the water relay unit 40 is placed can bend down. Then, the portion of the evaporation cloth 33 positioned below the middle portion is not bent straight down and bent so that adjacent evaporation cloths 33 stick to each other and thus the evaporation efficiency may be lowered. In order to solve this disadvantage, it is preferable to configure the at least the outermost mounting portion (31a) of the upper holder (31) with a L-shaped beam to have rigidity.

Next, with reference to FIGS. 2 to 5, the water relay unit 40, which is the most important component for determining the supply rate of water together with the holes 21 of the upper bucket 20 in the humidifier according to the present invention, will be described. Meanwhile, FIG. 5 is a partial cross-sectional view of the humidifier illustrated in FIG. 2 and shows the upper bucket 20 and the upper end of the evaporation unit 30 around the water relay unit 40.

The water relay unit 40 is mounted so as to be positioned between the upper bucket 20 and the evaporation bubble unit 30 to discharge water discharged from the holes 21 of the upper bucket 20. It is a component that distributes evenly to the evaporation cloth 33 to be relayed.

As described above, in the case of the humidifier disclosed in Patent Document 2, it is difficult and constant to control the supply rate of water, whereas the humidifier disclosed in Patent Documents 3 and 4 can finely control the supply rate of water, but the flow control valve or the drop amount regulator Is easily clogged and difficult to maintain such as cleaning.

The present inventors drill the hole 21 in the bottom surface of the upper bucket 20 to supply water from the top of the evaporation cloth 33, the diameter of the hole 21 is adjusted by the flow controller of Patent Documents 3 and 4 By making it larger than the diameter of the flow path (for example, about a few mm), a method has been devised for the general user to easily clean the hole 21 even if it is not blocked. However, if the diameter of the hole 21 is simply increased, water is discharged at a high speed far beyond the evaporation rate of the evaporation cloth 33 through the large hole, and there is little humidification effect (as described below, The water which flowed along the evaporation bubble 33 without being evaporated is stored in the lower bucket 50, but from the water accumulated in the lower bucket 50 and the lower bucket 50 back to the evaporator 33 by capillary action. The amount of water drawn up evaporates and contributes to the humidification is minimal).

Therefore, in the present invention, even if the diameter of the hole 21 of the upper bucket 20 is increased, the water relay unit 40 is devised so that water is not quickly discharged through the large hole 21. That is, in the humidifier of the present invention, the water relay unit 40 is in contact with the bottom surface of the upper bucket 20 while the upper end thereof blocks the hole 21 of the upper bucket 20, but does not completely block the hole 21. 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 water discharged through the holes 21 can flow out in small amounts along the surface of the water relay unit 40. In addition, the upper end of the water relay unit 40 is pressurized by the weight of the upper bucket 20 and the water stored in the upper bucket to close the hole 21 at an appropriate pressure. In addition, the lower end of the water relay unit 40 is made to contact the upper end of the plurality of evaporation cloth 33 caught in the upper cradle 31 is discharged through the hole 21 and a small amount through the surface of the water relay unit 40 The flowing water is relayed to the evaporation cloth 33 to be evaporated.

On the other hand, if the water in the upper bucket 20 decreases over time, the water pressure of the water discharged through the holes 21 decreases, so that if the force of the upper end of the water relay unit 40 to block the holes 21 is constant, There exists a possibility that the supply speed of water may fall with time. However, since the water relay unit 40 of the present invention is pressurized by the weight of the upper bucket 20 and the water stored in the upper bucket, the water relay unit 40 as much as the weight of the reduced water when the water in the upper bucket 20 is reduced ( The pressure applied to the upper end of the 40) is also reduced, thereby reducing the pressure blocking the hole 21, thereby offsetting the decrease in water pressure and supply speed over time, thereby naturally opening the hole 21 without any artificial manipulation. The amount of water discharged (feed rate) can be kept constant. In view of this, as described above, the projections 22 protruding laterally on the upper outer periphery of the upper bucket 20 are not caught on the upper surfaces of the L-shaped beams 12a arranged horizontally on the upper end of the frame 10. It is desirable to. That is, it is preferable that the upper bucket 20 has a structure capable of naturally pressing the water relay unit 40 according to the weight of the upper bucket 20 and the water stored therein.

In the present embodiment, the water relay unit 40 includes a relay block 41, a relay dish 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 bucket 20 to block the hole 21. The relay block 41 may be made of a material having at least a surface absorbent, such as a sponge, so as not to completely occlude 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 having no absorptivity, and has a water absorbent relay cloth (first relay cloth 42). You can also wrap it with As the first relay fabric 42, a woven fabric, a nonwoven fabric, paper, or the like of the same material as the above-described evaporation cloth 33 can be used.

In addition, as shown in Figure 5, the upper surface of the relay block 41, the groove having a diameter larger than the diameter of the hole 21 at a position corresponding to the hole 21 of the upper bucket 20 41a) is formed. This groove 41a is not essential but is an auxiliary means of controlling the force blocking the hole 21 by the relay block 41 and thus the rate of supply of water. That is, even if the groove 41a is not present, the hole 21 can be closed at an appropriate pressure by the relay block 41 and the first relay cloth 42 wrapped on the surface thereof, but this groove 41a is used for a long time. Presses the first relay 42 positioned above the relay block 41 to desorb absorbent to block the hole 21 with excessive pressure (as a result, the supply speed of water decreases) or, conversely, the hole 21 The damping force is lowered to cushion the increase in the supply speed of water, thereby providing a constant pressing force, and temporarily storing water discharged through the hole 21.

The relay dish 43 is disposed under the relay block 41 to receive the relay block 41 wrapped in the first relay cloth 42, and the lower end 43 is disposed to contact the upper ends of the plurality of evaporation cloths 33. It is a component in the form of a dish or tray. The relay plate 43 temporarily buffers the water discharged through the hole 21 and flows down through the first relay cloth 42 covering the outer surface of the relay block 41 to buffer the increase and decrease of the water supply speed. At the same time, the water to be supplied is spread evenly over the entire evaporation cloth 33. To this end, the relay dish 43 is wrapped in 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 of the same material as the above-described evaporation cloth 33 can be used. In addition, the relay dish 43 is set so that at least the Y-axis length of the relay dish 43 is equal to or greater than the Y-axis length of the upper cradle 31 so that the water can diffuse into the entire plurality of evaporation cloths 33. do.

On the other hand, as long as the feed rate of water is kept constant by the relay block 41 and the water can be evenly spread over the entire evaporation cloth 33, the relay dish 43 may be omitted. In this case, however, the size of the relay block 41 should be set so that the length of the Y-axis direction of the relay block 41 is greater than or equal to the length of the Y-axis direction of the upper holder 31.

On the other hand, the configuration of the water relay unit 40 as described above can be made relatively large in the hole 21 of the upper bucket 20, even if the diameter of the hole 21 is excessively large or excessively small It is not desirable. If the diameter of the hole 21 is excessively large, even if the water relay unit 40 is blocked while pressing, the discharge rate (supply rate) of water through the hole 21 may be excessively large. On the contrary, if the diameter of the hole 21 is excessively small, the discharge speed of the water may drop excessively or may not be discharged due to the cohesion 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 can be changed according to the overall size or capacity of the humidifier.

In addition, in the present embodiment, the hole 21 is illustrated and described as being drilled in the center of the upper bucket 20, but when the size of the humidifier, that is, the upper bucket 20 is large, a plurality of holes can be drilled. The diameter of the holes 21 can be appropriately reduced depending on the number of holes.

As such, the diameter or number of holes 21 drilled on the bottom surface of the upper bucket 20 is an important factor in controlling the supply speed of water. It is desirable to be able to easily control the supply rate of water by adjusting the diameter or number of.

To this end, a plurality of holes having the same or different diameters may be drilled in the bottom surface of the upper bucket 20, and the plurality of holes may be selectively opened or closed when the humidifier is used. Specifically, a plurality of holes having various diameters are drilled in the bottom surface of the upper bucket 20, and a combination for obtaining an optimum water supply rate through trial and error is selected, and then holes not belonging to the combination are adhesive tapes. To block it. Alternatively, a stopper made of, for example, rubber for each hole may be provided to block and block holes not belonging to the optimum combination.

The humidifier according to the present embodiment may further include a lower bucket 50 disposed below the evaporation cloth unit 30. The lower bucket 50 is a bucket that receives water that has not been evaporated by flowing along the plurality of evaporation cloths 33, and is an element for preventing water that has not evaporated and flowed down to the floor of the room. However, when all the water which flowed along the some evaporation cloth 33 evaporates, or when some water may flow to the floor of the room, this lower bucket 50 may be abbreviate | omitted.

On the other hand, when provided with a lower bucket 50, the plurality of evaporation can 33 may be such that the lower end (33a) to reach the bottom of the lower bucket (50). This is a slight but additional after the water in the upper bucket 20 is exhausted and all the water evaporated by the evaporation can (33), the water accumulated in the lower bucket (50) by lifting 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 examples. However, the specific configuration described in the present embodiment is only one preferred embodiment of the present invention, and does not represent all of the technical idea of the present invention, various equivalents and modifications that may be substituted for them at the time of the present application are It should be understood that there may be.

In addition, a hemispherical groove 41a having a radius of 13 mm was formed at a position corresponding to the hole 21 of the upper bucket 20 at the center of the upper surface of the styrofoam.

As the relay plate 43, a square plate having a width (X axis length): 150 mm, a length (Y axis length): 220 mm, and a height of the jaw (Z axis length): 20 mm, was used as the second relay cloth 44. The relay dish 43 was wound twice and wrapped with the same nonwoven fabric as a 1st relay fabric.

(4) evaporation unit (30)

In the same manner as the frame 10, a stainless steel sheet having a thickness of 1 mm was laser cut and bent to produce an upper cradle 31 and a lower cradle 32 as shown in FIG. At this time, the width of the mounting portions 31a and 32a of the upper mounting bracket 31 and the lower mounting bracket 32 was 15 mm, and the interval between the mounting portions 31a and 32a was 15 mm, so that the length (Y-axis length) was 225 mm. And the width (X-axis length) were 270 mm.

Eight pieces of the same nonwoven fabric as the first intermediate fabric 42 cut to a length of 1260 mm and a width of 260 mm were prepared to be an evaporation cloth 33, and an intermediate portion of each evaporation cloth 33 was placed on the upper holder 31. Hanging on each mounting portion (31a) hangs under the corresponding mounting portion (32a) of the lower holder 32, coarse coupling of both ends of the evaporator (33) by a snap button to make a loop shape. The distance between the upper cradle 31 and the lower cradle 32 in the completed evaporation cloth unit 30 was about 520 mm, and the lower end of the evaporation cloth 33 hanging down below the cradle 32a of the lower cradle 32 ( 33a) was about 80 mm long.

(5) Lower Bucket (50)

A horizontal plastic (X-axis length): 260 mm, vertical (Y-axis length): 190 mm, height (Z-axis length): 60 mm size transparent plastic barrel was used as the lower bucket (50).

Each component prepared as described above was assembled / combined with a humidifier as shown in FIG. 2. At this time, the protrusion 22 protruding laterally from the top of the upper bucket 20 was positioned about 2cm higher from the top of the frame 10.

An experiment was conducted to measure the humidification effect of the humidifier produced as described above. The experimental conditions were about 1.6 L of tap water in the upper bucket 20 while all components of the humidifier including the evaporator 33 were dry in a room maintained at a relative humidity of about 30% and a temperature of about 20 ° C. (The initial level of the upper bucket: 30 mm), the amount of water contained in the upper bucket 20 over time (decreased level), the evaporation of the evaporation can be soaked downward from the top of the evaporation cloth 33 by the water supplied The amount (water level) of water accumulated in the length and the lower bucket 50 was measured. On the other hand, the humidification effect is not measured by measuring the changing humidity of the room, but by measuring the amount of water (reduced water level) reduced in the upper bucket 20 and the amount of water that accumulates in the lower bucket 50 over time. It was evaluated by considering that a reduced amount of water was evaporated to contribute to humidification.

When 5 minutes had elapsed since the start of the experiment, all of the relay fabrics 42 and 44 surrounding the relay block 41 and the relay dish 43 were wetted, and the evaporation cloth 33 was not wetted yet. After the experiment (when all the water in the upper bucket 20 is exhausted), the relay cloth 44 wrapped in the relay dish 43 was kept in a wet state, but the water is not accumulated in the relay dish 43 Was maintained. Hereinafter, the result measured over time is put together in the table below.

Elapsed time
(time) Water level of upper bucket
(mm) Wet length of evaporation cloth
(cm) Water level in the lower bucket
(mm) 0.5 25 5-10 0 One 23 20-25 0 2 19 40-50 0 3 16 All (except for the outermost evaporation can no longer increase 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 bucket 20 is exhausted, and since the water is not accumulated in the lower bucket 50 until the end of the experiment, about 1.6L of water is about 6 to 7 hours. It can be seen that it evaporates evenly over. This amount of evaporation and the rate of evaporation can be said to be practical enough in view of the evaporation rate and evaporation rate of a conventional ultrasonic humidifier.

On the other hand, in Table 1, the length of the evaporation cloth was slightly wet depending on the position of the evaporation cloth, in particular, the outermost evaporation cloth was less wet, but was generally evenly wetted, and the outermost evaporation cloth was less wet. It is thought to be due to the most active evaporation in the outermost evaporation cloth. In addition, when 3 hours or more passed, the evaporation bubble 33 was fully wetted to the evaporation bubble lower end part 33a hanged to the bottom of the lower bucket 50, but it did not collect in the lower bucket 50. From this, it can be seen that the rate of evaporation of water by the evaporation cloth 33 and the rate of supply of water to the evaporation cloth 33 almost matched.

Here, when calculating the average feed rate of water, it is 1600 ml ÷ 360 minutes ≒ 4.44 ml / min ≒ 0.074 ml / second, assuming that 1.6L of water is constantly supplied over 6 hours, which is also referred to as a drip flow control valve It can be seen that the trace is difficult to adjust.

Next, as a comparative example, in order to confirm the humidification efficiency of the same method as Patent Document 1 that supplies water from the lower part to the upper part by capillary action, the humidifier according to the embodiment of the present invention is used under the same conditions, but the upper bucket ( 20) contained the same amount (1.6L) of tap water only in the lower bucket 50 without supplying water, and measured the amount of water decreasing with time. As a result, the rate of water evaporation (the rate at which the water decreases) drops remarkably so that accurate measurement is difficult (at the time of 14 hours, the level of the reduced water is about 20 mm, the amount is only about 0.98 L). It was found that the natural evaporative humidifier in the same manner as 1 was not practical.

As described above, according to the humidifier of the present invention, water can be supplied to the evaporation cloth at an appropriate and constant speed in accordance with the evaporation rate of water, and thus a humidifier that is sufficiently practical can be provided without using extra energy such as electric power. In addition, 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 bucket 20 and filling the upper bucket 20 with water, and easy to clean only parts. Humidifier is configured, the hole 21 of the upper bucket 20 is not small enough to be easily clogged, even a general user can use for a long time without any particular problem.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto and will be described by the person skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims.
