Description

Natural Evaporation Type Humidifier

The present invention relates to a humidifier that humidifies by a natural evaporation method without using a separate power such as electric power.

Electric humidifiers are widely used to increase indoor humidity in dry indoor environments. Most conventional electric humidifiers generate water vapor in an ultrasonic method or by heating and boiling water. These electric humidifiers have problems with contamination or bacterial propagation due to long-term use, so they need to be cleaned periodically. In addition, although the electric humidifier consumes a small amount of power, there is a problem that noise is generated during operation, which interferes with a good night's sleep.

Patent Document 1 (Public Utility Model Publication No. 20-2011-0005315) vertically hangs a plurality of towels and submerges the lower part of the towel in the water contained in the lower water tank, so that the water contained in the lower water tank by the capillary phenomenon is removed from the towel. Disclosed is a towel humidifier that naturally evaporates by pulling it up through the air. However, in this type of natural humidifier, the amount of water drawn up to the towel due to capillary action is insignificant, so the actual humidifying effect is insignificant (as shown in the experimental example to be described later, the amount of water that is evaporated by this method and contributes to humidification is extremely little).

Accordingly, in Patent Document 2 (Patent Publication No. 10-1172249) and Patent Document 3 (Patent Publication No. 10-2011-0018622), by supplying water from the upper part of the hanging towel (evaporative foam), evaporation Water for evaporation is supplied smoothly to the bag. However, in Patent Documents 2 and 3, the speed of water supplied from the upper portion is extremely slow in accordance with the evaporation rate of water in the evaporator. As a mechanism for adjusting such a water supply rate, a flow rate control valve (patent document 2) or the dripping amount regulator of a Ringer hose (patent document 3) is used.

However, the present inventor has experienced several times that these flow control valves or dripping volume controllers are easily clogged due to mineral components or impurities contained in water, and thus do not perform their functions in a short period of time. Of course, when these flow control valves or drip regulators are clogged, they can be cleared by cleaning, but it is not easy to clean and in light of the very slow water supply rate, even a small damage has a big effect on the supply rate, so the general user needs to clean it. is practically impossible. Also, it is not practical to use ultrapure water (distilled water) without impurities or mineral components as water for humidification.

Accordingly, the present applicant has proposed a naturally evaporative humidifier capable of supplying evaporation water supplied from the upper part very slowly according to the evaporation rate of water in the evaporator without using a separate flow rate control valve or dripping amount regulator. . That is, the naturally evaporative humidifier according to Patent Document 4 (Patent Publication No. 10-2018-0052162) drills a hole having a diameter of 1 to 7 mm on the bottom of the upper bucket, and plugs this hole in the lower part of the upper bucket. It has a water relay unit made of a material having at least an absorbent surface so as not to completely occlude it. According to this, the opening/closing degree of the hole is appropriately adjusted by the water pressure and weight of the water stored in the upper bucket, so that the water supply speed can be controlled extremely slowly.

However, as the humidifier according to Patent Document 4 is also used for a long period of time, the absorbency of the water relay unit is not kept constant. can be difficult to control.

Patent Document 1: Public Utility Model Publication No. 20-2011-0005315 Patent Document 2: Registered Patent Publication No. 10-1172249 Patent Document 3: Laid-Open Patent Publication No. 10-2011-0018622 Patent Document 4: Unexamined Patent Publication No. 10-2018-0052162

As described above, although a natural evaporative humidifier that does not use a separate power has been proposed in the past, the humidifying effect is insignificant, it is difficult to control the supply rate (flow rate) of evaporation water, or cleaning or maintenance is difficult. For this reason, it is not widely disseminated.

The present invention was devised in consideration of the above problems, and there is no need to adjust the speed of supplying humidification water to the evaporator, exhibits a sufficient humidification effect, and does not require cleaning or maintenance or is very simple, so that general users can use it.

In addition, the evaporator unit may include: an upper cradle including a plurality of cradles disposed parallel to each other and a connection part connecting both ends of the plurality of cradles to each other; a lower cradle configured to be the same as the upper cradle; and a plurality of evaporating cloths each of which is hung while forming a loop on a pair of mounting portions corresponding to each other of the upper and lower cradles.

In addition, the evaporation unit may be detachably mounted to the frame.

In addition, the humidifier of the present invention may further include a protective net that protects the side surface of the frame by wrapping it in a net shape.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims should not be construed as being limited to their ordinary or dictionary meanings, and the inventor should properly understand the concept of the term in order to best describe his invention. Based on the principle that it can be defined, it should be interpreted as meaning and concept consistent with the technical idea of the present invention.

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

1 and 2, the humidifier according to the present embodiment largely includes a frame 10, an evaporation unit 20 and a lower bucket 40, and optionally a diffusion plate 30 or a protective net ( 50), or an upper cover (not shown) may be further provided.

The frame 10 maintains the overall shape of the humidifier, and is a component supporting the evaporator unit 20 , the lower bucket 40 , and the diffusion plate 30 , which are the remaining components. The frame 10 is manufactured by connecting / assembling / adhering a plurality of metal rods, pipes, beams or plates by means such as welding, bolts, rivets, and adhesives, or a plurality of plastic rods, pipes, beams or plates in male and female types. It can be manufactured by molding in a combined shape and assembling them or connecting/adhesive using a connector or adhesive.

In this 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 to 12d arranged horizontally, and the upper middle of the frame 10 and It is divided into an upper part, a middle part, and a lower part by the L-shaped beams 12b and 12c which are arranged horizontally in the middle of the lower part. Here, it goes without saying that the overall shape of the frame 10 or the shape or number of each component can be changed as much as possible. For example, by omitting the L-shaped beams 12c arranged horizontally in the middle of the lower side, the evaporation unit 20 may be mounted on the L-shaped beams 12b arranged horizontally in the middle of the upper side and hang down.

A diffusion plate 30 is mounted on the upper portion of the frame partitioned by the horizontally arranged L-shaped beams 12a at the top and the L-shaped beams 12b in the upper middle, and the upper surface of the upper middle L-shaped beams 12b is described later. Both ends of the upper holder 21 of the evaporating foam unit 20 are mounted to mount the evaporating foam unit 20 in the middle of the frame, and the lower holder 22 of the evaporating foam unit 20 is located at the lower portion of the frame. Both ends and the lower bucket 40 of the are disposed.

On the other hand, when the diffusion plate 30 is omitted, the L-shaped beams 12b arranged horizontally in the middle of the upper side are also omitted so that the evaporation unit 20 is mounted on the L-shaped beams 12a arranged horizontally at the top. It can also be made into a hanging form.

The evaporator unit 20 is a component that is mounted on the frame 10 and allows the evaporation water supplied from the upper and lower portions to evaporate, although described later in detail.

In the present embodiment, the evaporation unit 20 includes an upper holder 21 , a lower holder 22 , and a plurality of evaporation cloths 23 .

The upper cradle 21 and the lower cradle 22 have substantially the same basic structure, and similarly to the above-described frame 10, metal or plastic rods, pipes, beams or plates are combined/assembled/molded to produce can The upper cradle 21 and the lower cradle 22 are, as shown in FIG. 3 , a plurality of cradles 21a and 22a arranged parallel to each other and both ends of the plurality of cradles 21a and 22a, respectively. Including the connecting portions (21b, 22b) for connecting to each other is made in the form of a ladder. At this time, the outer side end of at least the upper cradle 21 of the plurality of cradles 21a and 22a is bent perpendicular to the plane formed by the cradles 21 and 22 to form a L-shaped cradle. It is preferable to form This is to prevent deformation such as bending of the upper holder 21 downward due to the load when the diffusion plate 30 to be described later is placed on the upper holder 21 .

In the present embodiment, the upper cradle 21 and the lower cradle 22 may be manufactured by processing a plate material on a flat plate into a ladder shape by a method such as punching processing or laser cutting. Alternatively, the mounting portions 21a and 22a and the connecting portions 21b and 22b of the upper holder 21 and the lower holder 22 are made of a flat plate, respectively, and both ends of the mounting portions 21a and 22a and the connecting portion 21b , 22b) can be manufactured in the form of a ladder by being connected by rivets, welding, gluing, or the like. At this time, the distance between the width of the mounting portions 21a and 22a and the adjacent mounting portions 21a and 22a is 0.5 to several to prevent the evaporation fabrics 23 hanging down from sticking to each other and lowering the evaporation efficiency. set in cm.

In addition, the mounting portions 21a and 22a of the upper and lower cradles 22 correspond to each other and form a pair, and one evaporating cloth 23 is hung on each pair of the holders 21a and 22a in the form of a loop. The evaporating cloth 23 that hangs downward as much as the number of (21a, 22a) is combined. The evaporating cloth 23 is made of woven, non-woven, or paper made of natural or synthetic fibers having good water absorption and evaporation efficiency, and commercially available products such as kitchen towels or non-woven fabrics for cleaning can be used.

As described above, the evaporator unit 20 including the upper holder 21 , the lower holder 22 and the plurality of evaporators 23 is mounted on the frame 10 , specifically, the upper cradle of the evaporator unit 20 . The both ends connection part 21b of (21) is placed on the upper surface of the L-shaped beams 12b in the middle of the upper side of the frame 10, and the both ends connection part 22b of the lower holder 22 of the evaporator unit 20 is connected to the frame It may be mounted to be positioned below the L-shaped beams 12c in the middle of the lower side of (10).

Meanwhile, the evaporation unit 20 may be detachably mounted to the frame 10 . For this purpose, for example, as shown in FIGS. 1 and 2 , in the front of the vertically arranged L-shaped beam 11 , the height above the upper surface of the L-shaped beams 12b in the middle of the upper side and the middle of the lower side Cut-out grooves 11a and 11b are respectively formed at the height just below the lower surface of the L-shaped beams 12c, and both ends of the upper holder 21 are connected to the cut-out grooves 11a and 11b in the connecting portions 21b and the lower holder 22 ) by inserting the connecting portions 22b at both ends, respectively, and pushing in the Y-axis direction, so that it can be configured to be mounted. Alternatively, the evaporator unit 20 is inserted from the top down into the rectangular space formed by the horizontally arranged L-shaped beams 12a at the top of the frame 10 and mounted by mounting on the upper middle L-shaped beams 12b. You may.

As described above, the evaporation unit 20 is manufactured in a form separated from the frame 10 and can be mounted/removed on the frame 10, so that the evaporation cloth 23 can be removed using a humidifier for a long period of time (eg, one season). When it is dirty or damaged, such as torn, the evaporator unit 20 can be separated from the frame 10 to replace only the evaporator 23 and mounted on the frame 10 again.

On the other hand, the upper holder 21 of the evaporator unit 20, especially when the mounting portion 21a of the upper holder 21 is made of a thin plate, as described above, the weight of the diffusion plate 30 placed thereon can cause the middle part to bend downwards. Then, the evaporating fabric 23 located below the middle part cannot be straightened downward, but is bent, so that the adjacent evaporating fabrics 23 stick to each other, thereby reducing the evaporation efficiency. In order to solve this disadvantage, it is preferable to configure at least the outermost mounting portion 21a of the upper holder 21 as a L-shaped beam or a T-beam to have rigidity.

The lower bucket 40 is an element for receiving and accommodating evaporation water which is disposed below the evaporation unit 20 and is supplied from the upper part of the evaporation cloth unit to wet the plurality of evaporation cloths 23 and flows down. The lower bucket 40 is mounted on the lower portion of the frame 10 .

In addition, the lower bucket 40 is configured to accommodate the lower ends of the plurality of evaporating cloths (23). In this case, it is preferable that the plurality of evaporating cloths 23 have their lower ends 23a in contact with the bottom of the lower bucket 40 . This is to ensure that the evaporation water contained in the lower bucket 40 is pulled up to the last to the evaporation cloth 23 and used for humidification as the water wetted with the evaporation cloth 23 is evaporated and used for humidification.

The optional diffusion dish 30 is disposed on the top of the evaporation unit 20 and is a component in the form of a dish or tray that diffuses water for evaporation supplied from the upper portion to the plurality of evaporation cloths 23 .

The diffusion dish 30 comes into contact with the top of the plurality of evaporation cloths 23 by being placed on the evaporation unit 20 , in particular, on the upper holder 21 . In this case, the diffusion plate 30 may have a bottom of a size capable of simultaneously covering the upper ends of the plurality of evaporating cells 23 . That is, as shown in FIGS. 1 and 2 , at least the Y-axis direction length of the diffusion plate 30 may be set to be substantially equal to or greater than the Y-axis direction length of the upper holder 21 . As will be described later, when water for evaporation is supplied from the upper part of the evaporation unit 20, the water for evaporation flows down while passing through the diffusion plate 30 while evenly wetting the plurality of evaporation cloths 23. to do

In addition, a plurality of through-holes (holes) 31 penetrating the bottom of the diffusion plate 30 are formed. This is also for the diffusion of the evaporation water supplied from the upper portion of the evaporation unit (20). Here, the number or shape of the through-holes 31 is not limited to the illustrated example and can be variously changed.

Further, in the drawing, the diffusion dish 30 is shown as an element placed on the upper end of the evaporation unit 20, that is, on the upper cradle 21, but the diffusion dish 30 is, for example, on the upper L-shaped beam 12a of the frame. It may be mounted or attached, and further, when pouring and supplying water for evaporation from the upper part of the evaporation unit 20, the plurality of evaporation cloths 23 are evenly wetted and poured with a watering means such as a kettle or a watering can. The plate 30 may be omitted.

The protective net 50, which is an optional component, is a component for preventing damage such as tearing of the evaporation cloth 23 by careless handling by wrapping the side surface of the frame 10 in a net shape. The protective net 50 is made in the form of a net made of synthetic resin or metal, and may have some degree of flexibility. Therefore, it can be mounted on the side of the frame 10 by opening the protective net 50 and wrapping the side of the frame 10 , and then tightening it with a string 51 .

On the other hand, the element shown as '60' in FIG. 1 fixes the lower holder 22 to the L-shaped beam 12d horizontally disposed at the bottom of the frame so that the evaporation unit 20 does not flow laterally. As a string, it is useful especially when the L-shaped beam 12c arranged horizontally in the middle of the lower side of the frame is omitted.

An optional component, a top cover (not shown), is a component that rests on top of the frame 10 . The upper cover is made of a plate material such as cedar or juniper to emit a subtle scent and prevents foreign substances such as dust from penetrating into the diffusion plate 30 or the evaporation unit 20 during use.

Next, the operation of the humidifier according to the present invention configured as described above and the humidifying method according to the present invention will be described.

In the humidifier according to the present invention, as in Patent Documents 2 and 3 described above, water for evaporation is once supplied from the upper portion. However, unlike the humidifiers of Patent Documents 2 and 3 described above, the humidifier according to the present invention does not use a flow rate control valve or a drip rate regulator for controlling the water supply rate very slowly according to the evaporation rate of water.

That is, in the humidification method according to the present invention, first, water for evaporation is supplied from the upper portion of the evaporator unit 20 of the humidifier as described above by using a watering means such as a kettle. At this time, the water supply speed is not particularly slow, and the water is supplied at a normal speed so as not to splash water like when pouring water into a cup.

However, it is preferable to supply the evaporation water so that it flows down while spreading to the plurality of evaporation cloths, that is, while evenly wetting the plurality of evaporation cloths. For this purpose, the aforementioned diffusion plate 30 may be used. Even when the diffusion dish 30 is used, there is no need to adjust the speed such as pouring water into the diffusion dish 30 again after all the water poured into the diffusion dish 30 flows downward through the through hole 41, and the diffusion dish 30 is not required. The water poured into (30) may overflow the diffusion plate (30).

In this way, the water supplied from the upper part of the evaporator unit 20 wets the plurality of evaporating fabrics 23 and flows down and is accommodated in the lower bucket 40 , and the lower ends of the plurality of evaporators 23 are lowered into the lower bucket 40 . ) is immersed in the evaporation water contained in the

Thereafter, the evaporation water soaked in the plurality of evaporating cloths 23 is evaporated and humidification is performed naturally, and the evaporation water accommodated in the lower bucket 40 is supplied to the plurality of evaporating cloths 23 . That is, the water for evaporation is initially supplied from the upper portion (via the diffusion plate), but is subsequently supplied by capillary action from the lower portion (lower bucket 40 ).

In other words, compared to the humidifier of Patent Document 1 described above, which supplies water for evaporation only from the bottom, in the humidifier and humidification method according to the present invention, by supplying water for humidification by pouring water from the top first, the water for evaporation is It is different in that it flows down while wetting the evaporation cloth 23 and further undergoes a step of being accommodated in the lower bucket 40 .

As described above, the present invention differs from Patent Document 1 only in that humidification is started in a state in which the evaporation cloth 23 is sufficiently wetted by supplying water from the upper portion, but the evaporation efficiency (humidification efficiency) is remarkably different.

Hereinafter, a humidifier according to an embodiment of the present invention will be described with reference to specific examples and experimental examples. However, since the specific configuration described in this embodiment is only a preferred embodiment of the present invention and does not represent all the technical spirit of the present invention, various equivalents and modifications that can replace them at the time of the present application are provided. It should be understood that there may be

The humidifier of this embodiment has the configuration as shown in FIGS. 1 to 3 and described in the above-described embodiment, and was manufactured with the following specifications.

(1) Frame(10)

The frame 10 was manufactured using a cross-sectional L-shaped aluminum beam with a thickness of 1 mm and a side width of 12 mm, and the overall size was horizontal (X-axis length): 300 mm, vertical (Y-axis length): 235 mm, height (Z-axis). Length): It was set as 630 mm.

(2) Diffusion dish (30)

Horizontal (X-axis length): 100 mm, vertical (Y-axis length): 210 mm, height (Z-axis length): a square plate of 28 mm size was used, and 44 through holes 31 having a diameter of 4 mm were formed at the bottom.

(3) Evaporating foam unit (20)

By cutting the plastic plate, the upper holder 21 and the lower holder 22 as shown in FIG. 3 were manufactured. At this time, the width of the mounting portions 21a and 22a of the upper holder 21 and the lower holder 22 was 15 mm, and the interval between the mounting portions 21a and 22a was 15 mm, so that the vertical (Y-axis length) was 215 mm. , the width (X-axis length) was set to 285 mm.

Eight sheets of KJW series nonwoven fabric manufactured by Kwangjin Industrial Co., Ltd., cut to length: 1260mm and width: 260mm were prepared as evaporator 23, and the middle part of each evaporator 23 was placed on the upper holder 21. It was hung on the part 21a, and both ends of the evaporator 23 were loosely coupled with snap buttons under the corresponding mounting part 22a of the lower holder 22 to form a loop. The distance between the upper holder 21 and the lower holder 22 in the completed evaporator unit 20 was about 510 mm, and the lower end of the evaporator 23 hanging down under the holder 22a of the lower holder 22 ( 23a) The length was about 80 mm.

(4) lower water tank (40)

Width (X-axis length): 260mm, vertical (Y-axis length): 190mm, height (Z-axis length): a transparent plastic bucket of the size of 70mm was used as the lower bucket (40).

Each component prepared as above was assembled/combined to constitute a humidifier as shown in FIG. 1 .

An experiment was conducted to measure the humidification effect with respect to the humidifier manufactured as described above. Experimental conditions, relative humidity: about 30%, temperature: about 3.8 of tap water at room temperature through the diffusion dish 30, in a room maintained at about 20 ° C. By pouring L, the evaporation cloth 23 was evenly wetted and flowed down to fill the lower water tank 40 (water level: 70 mm). From the size of the lower bucket 40 (260mm × 190mm × 70mm), the amount of water contained in the lower bucket was calculated to be 3,458ml.

Thereafter, the amount of water (water level) contained in the lower bucket 40 was measured in units of one hour. On the other hand, the humidification effect is not measured by measuring the changing indoor humidity, but by measuring the amount (water level) of water contained in the lower bucket 40 over time, the actual reduced amount of water is evaporated and contributed to humidification It was evaluated by considering that it did. Hereinafter, the results measured over time are summarized in the table below.

elapsed time lower water level Reduced water volume in the lower water tank (per hour) Reduced amount of water in lower reservoir (cumulative) 1 hours 69mm 49ml 49ml 2 hours 63mm 296ml 346ml 3 hours 58mm 247ml 597ml 4 hours 53mm 247ml 840ml 5 hours 49mm 198ml 1,037m 6 hours 44mm 247ml 1,284ml

As shown in Table 1, the water in the lower bucket 40 did not decrease much at first, which is mainly due to evaporation (humidification) of the water soaking the evaporator 23 during the initial 1 hour, and the water in the lower bucket 40 is evaporated. It is assumed that the result did not contribute much to the However, with the lapse of time, the water level in the lower water tank decreased by an average of 5 mm per hour, an average of about 250 ml per hour, and after 6 hours, a total of 1,284 ml of water was reduced. On the other hand, after 6 hours, the upper end of the evaporator 23 was in a slightly dry state, but the water in the evaporating cloth was about 50 mm below the upper end (upper holder 21) (from the lower holder 22 to about 460 mm above). It was not dry.

From this, about 1.6L of water is consumed for humidification for 6 hours (about 1.3L of the reduced amount of the lower bucket for 6 hours + about 0.3L of the amount of water that wetted the evaporator 23 used for evaporation during the initial 1 hour) Considering that, it can be said that it is a sufficiently practical level in view of the humidification efficiency of a conventional ultrasonic humidifier.

Then, as a comparative example, in order to confirm the humidification efficiency of the same method as in Patent Document 1 in which water is supplied only from the lower part to the upper part by capillary phenomenon, the humidifier according to the embodiment of the present invention is used under the same conditions, but from the upper part The same amount (3,458ml) of tap water was immediately placed in the lower bucket 40 without watering, and the amount of water decreased over time was measured. As a result, the change in the water level per hour of the lower bucket 40 was insignificant enough to be difficult to measure. That is, it was found that the water level decreased after 6 hours was about 8 mm, and the amount was only 395 ml. In addition, the height at which the evaporation cloth 23 was wetted, that is, the height of the water pulled up by the capillary phenomenon at the time of the lapse of 6 hours did not exceed about 200 mm from the lower holder 22 .

As described above, it is considered that the following reason is the reason why the method of the present invention and Patent Document 1 differs significantly in effect even though it differs only in whether or not water is initially supplied from the upper part.

That is, in the case where the evaporation cloth 23 is sufficiently wetted by first pouring water from the upper part (the method of the present invention), the water molecules soaking the evaporation cloth 23 are compared to the dry evaporation cloth (the method of Patent Document 1). It is thought that the cohesive force and surface tension of This is the same principle as if water is smoothly supplied from the root to the top of a tree in a tall tree where water cannot rise to the top through simple root pressure and capillary action alone.

As described above, according to the present invention, the water for evaporation contained in the lower bucket 40 is supplied to the evaporation cloth 23 at the upper part, but by first pouring water from the upper portion to sufficiently wet the evaporation cloth 23, the capillary phenomenon is prevented. It is possible to provide a sufficiently practical humidifier without using additional energy such as electric power by facilitating the supply of water for evaporation.

Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto and will be described below with the technical idea of the present invention by those of ordinary skill in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims.
