BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying device used in a heating device or the like to prevent indoor air from drying out, and more particularly to a humidifying device equipped with a humidifying element, a water tank, and a drain receiver.

2. Description of the Related Art Conventionally, this type of humidifying device is disclosed in, for example, Japanese Patent Laid-Open No. 1-102227, and as shown in FIG. A, a water tank B for storing water to be supplied to the element A, and a drain receiver C for receiving water falling from the humidifying element A, and the humidifying element A is arranged at a predetermined interval in the width direction of the air flow. There are several installed in parallel. In addition, each humidifying element A includes a suction part D that has one end immersed in the water tank B and sucks up the water in the water tank B, and a suction part D that is continuous with the suction part D and that absorbs the water sucked up by the suction part D. a water guide part E that guides the water, and a water guide part E that is continuous with the water guide part E;
Further, a humidifying section F is provided to evaporate the water guided through the water guiding section E, so that the water flowing down the surfaces on both sides of the humidifying section F is evaporated into the air flow passing between each humidifying element A. It is configured to humidify by

[Problem to be solved by the invention] By the way, the water tank B
is supplied with city water, and this city water contains hardness components such as calcium, so if there is air flow in the water guiding section E, which has a high water content, this air flow The hard components precipitate due to contact with the water, and the precipitated hard components act as resistance to the movement of water to the humidifying section F in the water guiding section E, and the amount of hard components precipitated due to long-term humidification increases. increases from the wicking part D to the humidifying part F.
will not be able to move enough water to the Therefore, as shown by the dashed line in FIG. 4, a position in front of the water guide part E in the air flow direction is placed so that the moisture sucked up by the wicking part D and the water guide part E does not come into contact with the air flow. In this case, a shielding plate G is provided to prevent the water from entering, and a spacer or the like (not shown) is interposed between the humidifying elements A and at a position corresponding to the water guiding portion E. However, there was a problem in that the number of parts increased by providing the shielding plate G and the spacer, and there was also a problem in that the humidifying area could not be used effectively.

[0004] Furthermore, since the humidifying elements A have a structure in which they are arranged side by side in a plate shape, even if an attempt is made to increase the humidifying area per volume of the entire humidifying section F by narrowing the interval between the side-by-side arrangement of the humidifying elements A, If the spacing between the humidifying elements A is too narrow, the water flowing down the surface of the humidifying section F will form a water film, which will be blown away by the air flow, resulting in water scattering. Considering the problem, there is a limit to the spacing between the humidifying elements A, which makes it impossible to fully demonstrate the humidifying ability and also prevents miniaturization.

[0005]The present invention was invented to solve the above problems, and its purpose is to prevent hard components from wicking from the wicking part to the humidifying part, regardless of the precipitation of hard components caused by water evaporation in the water guiding part. The number of parts can be reduced by eliminating the conventional shielding plate and spacer, and the area in contact with the air flow in the humidifying section can be increased to achieve efficient humidification, increasing the humidifying capacity. The aim is to provide a humidifying device that can fully demonstrate the following.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises a humidifying element 3, a water tank 2, and a drain receiver 4. A suction part 34 that sucks up water from the aquarium 2, a water guiding part 35 that guides the water sucked up by the suction part 34,
A humidifying section 36 that goes from the water guide section 35 to the drain receiver 4
The humidifying element 3 includes a flat plate 31 made of a water-absorbing material, a horizontal corrugated plate 32 bent in the air flow direction, and the flat plate 31 and the air flow direction. It consists of a large number of unit units in which vertical corrugated plates 33 bent in orthogonal directions are laminated, and these unit units are connected to each other by water between the flat plate 31 and the horizontal corrugated plates 32 and vertical corrugated plates 33 adjacent to the flat plate 31. They were stacked in contact so that they could move.

[0007]

[Operation] Air supplied to the humidifying element 3 in the direction of the arrow passes through the horizontal corrugated gate 32 which is bent in the flow direction, whereas the air is bent in the direction perpendicular to the flow direction. It does not pass through the vertical corrugated plate 33. Therefore, from both surfaces of the horizontal corrugated plate 32 that come into contact with the air flow and from the surface of the flat plate 31 facing both sides of the horizontal corrugated plate 32, air is removed by evaporation of the water sucked up from the water tank 2. While air humidification is performed, the air flow does not contact the vertical corrugated plate 33, which is bent in a direction perpendicular to the air flow direction.
A suction part 34 and a water guide part 35 consisting of a flat plate 31 facing
In the water sucked up, there is no hardness component precipitated that acts as a resistance to the movement of the water, and the water can be effectively moved to the humidifying section 36 via the vertical corrugated plate 33 and the flat plate 31. It is. That is, while the horizontal corrugated plates 32 share the evaporation of water, the evaporation of water from the surface of the vertical corrugated plates 33 is prevented to prevent precipitation of hardness components, and the vertical corrugated plates 33 share the movement of water.

Therefore, even if hard components are deposited in the water guiding section 35 of the horizontal corrugated plate 32, the water sucked up from the wicking section 34 is transferred to the humidifying section 36 via the water guiding section 35. There is no problem with the supply of water to the humidifying section 36, and water can be sufficiently supplied to the humidifying section 36 without providing a shielding plate or spacer as in the conventional example, and as a result, the shielding plate etc. can be made unnecessary. , the number of parts can be reduced accordingly.

Furthermore, water moving through the vertical corrugated plate 33 that does not come into contact with the air flow is dispersed through the flat plate 31 to the horizontal corrugated plate 32, and is distributed between both surfaces of the horizontal corrugated plate 32 that are in contact with the air flow. , since it evaporates from one surface of the flat plate 31 facing both sides of the horizontal corrugated plate 32,
That is, the horizontal corrugated plate 3 has a larger area than the flat plate 31.
Since moisture can be evaporated from the flat plate 31, the humidifying area per volume of the entire humidifying element 3 can be increased, and humidification can be performed efficiently.

Moreover, since the flow of air passing through the approximately triangular gap defined by the horizontal corrugated plate 32 and the flat plates 31 facing both sides of the horizontal corrugated plate 32 is humidified,
Compared to the conventional example in which the humidifying elements A are arranged in parallel, a water film is less likely to form, so the size of the approximately triangular gap can be reduced, further increasing the humidification per volume of the entire humidifying element 3. The area can be increased, the humidifying capacity can be increased compared to the conventional example, and the whole can be made more compact.

[0011]

[Embodiment] As shown in FIG. 3, the humidifying device 10 shown in FIG.
It is used internally with a fan 25 that flows air in the direction of the arrow, and a heat exchanger 26 that acts as a condenser during heating and heats the air by heat exchange with the air flowing inside the casing 22. A water tank 2 disposed near the top of the air outlet 24, a humidifying element 3 that evaporates water supplied from the water tank 2, and a drain receiver 4 disposed below the heat exchanger 26 and the humidifying element 3. The humidifying element 3 includes a suction part 34 that is immersed in the water tank 2 and sucks up the water in the water tank 2, a water guide part 35 that guides the water sucked up by the suction part 34, and a water guide part 35 that guides the water sucked up by the suction part 34. A humidifying section 36 extending from the water guiding section 35 toward the drain receiver 4 is provided between the heat exchanger 26 and the air outlet 24 .

[0012] Also, a float switch 5 is installed in the water tank 2.
is provided so that the water level of the water tank 2 can be maintained constant by operating the float switch 5. Note that 6 is a solenoid valve that opens and closes according to instructions from the float switch 5.

[0013] The humidifying element 3 includes a flat plate 31 made of a water-absorbing material, a horizontal corrugated plate 32 bent in the air flow direction, and a horizontal corrugated plate 32 bent in the air flow direction. Bent vertical corrugated board 3
The flat plate 31 and the horizontal corrugated plates 32 and vertical corrugated plates 33 adjacent to the flat plate 31 are laminated in contact with each other so that water can move between them. That's what I did.

That is, for example, a large number of synthetic resin particles having hydrophilic properties are bonded under pressure to form a porous synthetic resin plate having water absorption properties, and the synthetic resin plate thus formed is used as the flat plate 31. As shown in FIG. 1, a large number of flat plates 31 are arranged side by side at intervals in the width direction of the air flow.

[0015] Further, the synthetic resin plate formed as described above is bent into a wave shape to form a corrugated corrugated plate,
This corrugated corrugated plate is alternately brought into contact with the horizontal corrugated plate 32 which is parallel to the air flow direction between the flat plates 31 and the vertical corrugated plate 33 which is perpendicular to the air flow direction. Two flat plates 31 are interposed in the shape of
. The humidifying element 3 is formed by allowing water to move between the two.

In the embodiment shown in FIG.
The water sucked up from the air is evaporated in the humidifying section 36 to humidify the air passing through the humidifying element 3 in the direction of the arrow, and the air flow passes through the horizontal corrugate 32 bent in the flow direction. and the horizontal corrugated plate 3
2 and the surface of the flat plate 31 facing both sides of the horizontal corrugated plate 32, the air flow is humidified by evaporation of water.

Further, there is no air flow through the vertical corrugated plate 33, which is bent in a direction perpendicular to the direction of air flow, and therefore, the sucked up water does not come into contact with air, so there is no flow of water. However, no hardness components that provide resistance precipitate. Therefore, the water absorbed through the vertical corrugated plate 33 and the flat plate 31 can be effectively supplied to the humidifying section 36. That is, while the horizontal corrugated plates 32 share the evaporation of water, the evaporation of water from the surface of the vertical corrugated plates 33 is prevented to prevent precipitation of hardness components, and the vertical corrugated plates 33 share the movement of water.

As described above, since there is no air flow in the vertical corrugated plate 33 and the sucked up water does not come into contact with air, the sucked up water can be moved effectively, so that it does not come into contact with the air flow. Even if hard components are deposited on the wicking part 34 and the water guiding part 35 of the horizontal corrugated plate 32, the water sucked up from the wicking part 34 passes through the water guiding part 35 to the humidifying part 36. This will ensure a reliable supply. Therefore, unlike the conventional example, there is no need to provide a shielding plate or a spacer, and the number of parts can be reduced accordingly.

Furthermore, as described above, water moving through the vertical corrugated plates 33 that do not come into contact with the air flow is
1 to the horizontal corrugated plate 32, and evaporates from both surfaces of the horizontal corrugated plate 32 that come into contact with the air flow and one surface of the flat plate 31 facing both sides of the horizontal corrugated plate 32. Since moisture is evaporated from the flat plate 31 and the horizontal corrugated plate 32, which has a larger area than the flat plate 31, the humidifying area per volume of the entire humidifying element 3 can be increased compared to the conventional example, It can humidify efficiently.

That is, the flat plates 31 have the same size, the same spacing between them, and the same thickness as the conventional humidifying element A shown in FIG. Let us consider the case where the horizontal corrugated plates 32 and vertical corrugated plates 33 to be installed have the same thickness and water is evaporated by circulating air under the same conditions.

In this case, in the present invention, the three flat plates 31 and the one horizontal corrugated plate 32 and the vertical corrugated plate 33 interposed between these flat plates 31 form one unit, so this is different from the conventional example. As a comparative example, a humidifying element A consisting of three flat plates is used.

In the embodiment shown in FIG. 1, as described above, water evaporates from both surfaces of the horizontal corrugated plate 32 and one surface of the flat plate 31 facing both sides of the horizontal corrugated plate 32. On the other hand, in the conventional example shown in FIG.
Water evaporates from one side of the surface. In this case, the area of one side of the flat plate 31 facing both sides of the horizontal corrugated plate 32 and the humidifying element A located between the conventional example
The surfaces of one side of the two humidifying elements A arranged in parallel on both sides are the same, whereas the area of both surfaces of the horizontal corrugated plate 32 is the area of the surfaces of both sides of the humidifying element A located in the middle of the conventional example. Compared to the corrugated shape, it is only larger. Therefore, as described above, the flat plate 31, the horizontal corrugated plate 32, and the vertical corrugated plate 33
When compared by arranging them at the same spacing as the conventional example shown in FIG. However, the humidifying area formed by the flat plate 31 and the horizontal corrugated plate 32 can be made larger than that of the three conventional humidifying elements A shown in FIG. 4, and the humidifying capacity can be improved accordingly.

Moreover, in the embodiment shown in FIG. 1, a substantially triangular gap is formed between the horizontal corrugated plate 32 and the flat plates 31 facing both sides of the horizontal corrugated plate 32.
Since air is circulated through this gap, a water film is less likely to be formed compared to the conventional humidifier which humidifies the flow of air passing through the gap between the humidifying elements A arranged in parallel. The spacing between the humidifying elements 31 can be narrower than that of the conventional example, and the humidifying area per volume of the entire humidifying element 3 can be further increased, allowing the humidifying ability to be fully exhibited.

Incidentally, if the length in the juxtaposed direction of a large number of humidifying elements each having a thickness of 2 mm is set to 290 mm, in the conventional example shown in FIG. 4, the humidifying elements A need to be arranged at intervals of 8.1 mm. Therefore, only 28 sheets can be arranged in parallel, whereas in the embodiment shown in FIG. Since the length can be made narrower, about 70 sheets can be stacked within the length of 290 mm. Therefore, together with being able to increase the humidification area of the horizontal corrugated board 32, the entire humidification area can be increased. In this case, the humidification area in the embodiment shown in FIG. 1 is approximately 3.6 times larger than that in the conventional example shown in FIG.

[0025]

As explained above, the present invention consists of a humidifying element 3, a water tank 2, and a drain receiver 4, and the humidifying element 3 is immersed in the water tank 2 to suck up water from the water tank 2. A humidifying device comprising a suction part 34, a water guiding part 35 for guiding water sucked up by the suction part 34, and a humidifying part 36 directed from the water guiding part 35 toward the drain receiver 4, the humidifying element 3 is a lamination of a flat plate 31 made of a water-absorbing material, a horizontal corrugated plate 32 bent in the air flow direction, and a vertical corrugated plate 33 bent in a direction perpendicular to the flat plate 31 and the air flow direction. These unit units are stacked in contact with a flat plate 31 and horizontal corrugated plates 32 and vertical corrugated plates 33 adjacent to the flat plate 31 so that water can move between them. Since it is characterized by While the corrugated plate 32 is responsible for the evaporation of water, the vertical corrugated plate 33, which is bent in a direction perpendicular to the air flow direction to prevent air from flowing, has a hardness component that acts as a resistance to the movement of water. This allows the vertical corrugated plates 33 to share in the movement of water while preventing the precipitation of water.

Therefore, even if hard components are deposited on the wicking parts 34 and water guiding parts 35 of the horizontal corrugated board 32, the wicking parts 3 of the vertical corrugated board 33
The moisture sucked up from the humidifying section 4 is effectively supplied to the humidifying section 36 via the water guiding section 35. As a result, moisture can be reliably supplied to the humidifying section 36 without providing a shielding plate or a spacer as in the conventional example, and the number of parts can be reduced accordingly.

Moreover, the water moving through the vertical corrugated plate 33 that does not come into contact with the air flow is dispersed through the flat plate 31 to the horizontal corrugated plate 32, and is distributed between both surfaces of the horizontal corrugated plate 32 that are in contact with the air flow. , because moisture is evaporated and humidified from one surface of the flat plate 31 facing both sides of the horizontal corrugated plate 32, that is, moisture can be evaporated from the horizontal corrugated plate 32, which has a larger area than the flat plate 31, and the flat plate 31. , the humidifying area per volume of the whole humidifying elements 3 arranged in large numbers can be increased, and humidification can be carried out that much more efficiently. flat plate 31
Since a substantially triangular gap is formed between the humidifying elements and the air passing through this gap is humidified, a water film is less likely to form compared to the conventional example in which the humidifying elements A are arranged in parallel. Therefore, the spacing between the flat plates 31 can be narrower than in the conventional example, and the humidifying area per volume of the entire humidifying elements 3 can be further increased, the humidifying capacity can be improved, and the overall size can be reduced. It becomes.
