Air flows in the direction indicated by the white arrow in FIG. In addition, although the air blower 5 is incorporated in the ventilation airflow upper side rather than the humidification element 2 in this Embodiment, it may be incorporated in the ventilation airflow lower side than the humidification element 2. FIG.

FIG. 2 is a perspective view of the humidifying element 2 included in the humidifying device 1 according to Embodiment 1. FIG. One or a plurality of humidifying elements 2 are directly installed on the drain pan 7 .

It is preferable that all of the connection parts of the water supply system, excluding the connection part with the water supply source side, be concentrated in the drain pan 7 .

FIG. 3 is a perspective view of the humidifying element 2 according to Embodiment 1. FIG. 4 is an exploded perspective view of the humidifying element 2 according to Embodiment 1. FIG. 5 is a front view of the humidifying element 2 according to Embodiment 1. FIG. FIG. 6 is a cross-sectional view of the humidifying element 2 shown in FIG. 5 along line VI-VI. In FIG. 6, hatching is omitted. Hereinafter, the width direction of the humidifying element 2 is defined as the X-axis direction, the depth direction of the humidifying element 2 is defined as the Y-axis direction, and the height direction of the humidifying element 2 is defined as the Z-axis direction. As shown in FIGS. 3 to 5 , the humidifying element 2 includes a large number of flat humidifiers 20 . A large number of humidifiers 20 are arranged with a gap therebetween along the X-axis direction. A gap between adjacent humidifiers 20 forms an air passage through which air can pass. The blower 5 shown in FIG. 1 generates an air flow from upwind to downwind and passes the air through the gaps between the humidifiers 20 . Air flows through the gaps between the humidifiers 20 from the + side to the - side in the Y-axis direction. As shown in FIG. 4, in the upper part of the humidifying body 20, the central part along the Y-axis direction is formed with a recessed part 23 that is recessed below other parts. A diffuser 30 is arranged in the recess 23 . The diffusion bodies 30 are arranged to extend along the X-axis direction, and the upper ends of the plurality of humidifying bodies 20 collectively contact one diffusion body 30 .

As shown in FIG. 6 , above the humidifier 20 , there are a water reservoir 12 for storing water to be supplied to the humidifier 20 and a water supply port 11 for injecting water from the water supply pipe 3 into the water reservoir 12 . Below the humidifying body 20, there are a drainage part 13 for receiving and draining water remaining unhumidified from the humidifying body 20, and a drainage port 13a.

As shown in FIGS. 3 and 4, humidifier 20 is housed inside casing 10 . The water supply port 11 and the drainage part 13 are formed in the casing 10 . The casing 10 is formed with a structural wall 14 that connects a water storage section 12 as an upper structure and a drainage section 13 as a lower structure. The drainage part 13 forms the bottom wall 10 e of the casing 10 .

The casing 10 is formed by injection molding or the like using thermoplastic plastic including ABS (Acrylonitrile Butadiene Styrene) resin, polystyrene (PS) resin, or polypropylene (PP) resin. As shown in FIG. 4, the casing 10 is divided into two parts, a first casing 10a and a second casing 10b. By sandwiching the humidifier 20 between the first casing 10a and the second casing 10b and aligning the engaging portions 15 of the first casing 10a and the second casing 10b, the first casing 10a and the second casing 10b are integrated to form a structure that accommodates the humidifier 20. As shown in FIG. In addition, the casing 10 only needs to accommodate the humidifier 20, and may be made of metal or metal and resin.

Each of the first casing 10a and the second casing 10b is provided with a portion that serves as a drain port 13a. Further, the second casing 10 b is provided with a water supply port 11 for supplying water to the water reservoir 12 and an opening 10 c for introducing air to be humidified into the humidifier 20 . Inside the casing 10, a housing space for housing the humidifier 20 is provided.

Positioning projections 10d for regulating the horizontal position of the humidifying body 20 are provided in portions of the first casing 10a and the second casing 10b that come into contact with the humidifying body 20, respectively. Since some of the humidifiers 20 contain water and are deformed by the weight of the water, the horizontal position of the humidifiers 20 is regulated by the outer peripheral portion of the humidifier 20 that contacts the first casing 10a and the second casing 10b. By preventing the entire humidifier 20 from being distorted, the dimensions of the air passage between the humidifiers 20 can be ensured, and the air can flow uniformly in the air passage between the humidifiers 20. - 特許庁As a result, the decrease in the pressure loss of the humidifying element 2 is suppressed, and the entire surface of the humidifying body 20 is effectively used as a humidifying surface, so the effect of increasing the amount of humidification can be expected compared to the case where the humidifying body 20 is distorted. .

The shape of the water supply port 11 shown in FIG. The water supply pipe 3 may be tied with a hose band. The water supply port 11 has no restrictions on its position as long as it has a structure that allows water to be supplied from the upper part of the humidifier 20. preferably placed on the windward side of the By doing so, water leaking from the joint between the water supply pipe 3 and the water supply port 11 rides on the air current and is guided to the leeward side, that is, the humidifying element 2 side, and is absorbed by the humidifying body 20. Therefore, the humidifying element Splashing of water to the leeward side of 2 can be reduced.

When the amount of water supplied to the humidifier 20 is excessive with respect to the amount of humidification from the surface of the humidifier 20 shown in FIG. water volume increases. Therefore, it is preferable that the water supply port 11 is provided with a mechanism for throttling the amount of water to adjust the amount of water supplied to the water storage section 12 . A mechanism for restricting the amount of water is, for example, the orifice section 40 . The orifice portion 40 is formed by narrowing a part of the inner peripheral surface of the water supply port 11 more than other portions. It should be noted that the orifice part 40 is sufficient as long as it is capable of adjusting the amount of water.

The water reservoir 12 is fixed to the casing 10 . Also, the water reservoir 12 is provided above the diffuser 30 . A plurality of water injection holes 12a, which are water injection portions for injecting water into the diffuser 30, are formed in the bottom surface of the water storage portion 12. As shown in FIG. The water reservoir 12 serves as water supply means for supplying water to the diffuser 30 . A water level detection sensor 8 for detecting the water level of the water storage section 12 may be installed inside the water storage section 12 . The water level detected by the water level detection sensor 8 may be fed back to control the opening and closing of the water supply valve 3a by the controller 6 shown in FIG.

The water reservoir 12 is made of a thermoplastic material including ABS resin, PS resin, or PP resin, and is formed by a molding method such as injection molding. If the water storage part 12 made of resin is used and the surface of the water storage part 12 is smoothed, the contact angle becomes approximately 90 degrees or more. Here, hydrophobicity is defined as a contact angle of 90 degrees or more, hydrophilicity is defined as a contact angle of 40 degrees or more and less than 90 degrees, and superhydrophilicity is defined as a contact angle of less than 40 degrees. In this embodiment, the contact angle on the surface of the water reservoir 12 is set to be approximately 90 degrees or more. As a result, the surface of the water storage portion 12 becomes hydrophobic, so there is an advantage that water is less likely to remain on the surface of the water storage portion 12 and the sanitation in the water storage portion 12 is improved. The water storage part 12 only needs to store water and supply the water to the humidifying body 20, and there is no functional problem even if the water storage part 12 is formed of a circular tube, a rectangular tube, or the like. Also, the material of the water reservoir 12 may be metal.

The diffuser 30 is made of a porous plate material. A diffuser 30 is fixed to the reservoir 12 . The diffuser 30 is arranged directly below the water injection hole 12a. The diffuser 30 absorbs water dripped from the water reservoir 12 and sends the water to the humidifier 20 . Therefore, if the surface of the diffuser 30 is as hydrophilic as possible, the permeability will be improved and the water flow rate will be increased. In addition, since the diffuser 30 is always in contact with water, it is preferable that the diffuser 30 be made of a material that is less likely to be degraded by water. The diffuser 30 made of a material that is not easily degraded by water includes polyester such as polyethylene terephthalate (PET) resin, a porous plate made of cellulose, and metals such as titanium, copper, and stainless steel. and porous plates. Further, in order to increase the hydrophilicity of the surface of the diffuser 30, the diffuser 30 may be subjected to hydrophilization treatment.

The lower end of the diffuser 30 and the upper end of the humidifier 20 are in contact with each other. If the diffuser 30 and the humidifying body 20 are in contact with each other, water flows down to the humidifying body 20 without stagnation due to the action of the capillary force of the humidifying body 20 .

The humidifier 20 is made of a porous plate like the diffuser 30 . Suitable conditions for the material of the humidifier 20 are the same as those of the diffuser 30 , and the same material as the diffuser 30 may be used for the humidifier 20 . However, if a material having better water absorption than the diffuser 30 is used for the humidifier 20 , the humidifier 20 absorbs water before the water is sufficiently diffused inside the diffuser 30 . Water supply may be less uniform. In this case, it can be dealt with by increasing the vertical dimension of the diffuser 30 . If there is a restriction on the height of the humidifying element 2 as a whole, the vertical dimension of the diffuser 30 is also restricted. , so that the vertical dimension of the diffuser 30 can be reduced.

As shown in FIG. 4, the surface of the humidifying body 20 is provided with convex portions 21 . The protrusions 21 maintain the spacing between the humidifiers 20 . The convex portion 21 can be formed by pressing a jig against the humidifying body 20 and plastically deforming the portion pressed against the jig. By alternately arranging two kinds of humidifying bodies 20 having different arrangement positions of the convex portions 21 on the humidifying bodies 20, a function of keeping the interval between the humidifying bodies 20 constant can be obtained. In addition, it is sufficient that the humidifiers 20 are kept at regular intervals along the X-axis direction. For example, a comb having cuts corresponding to the plate thickness of the humidifier 20 at regular intervals may be meshed with the humidifier 20 to maintain the interval. Moreover, the structure which maintains a space|interval by laminating|stacking the humidifying body 20 shape|molded in a wave shape in a honeycomb form may be sufficient, and the structure which inserts a spacer between the humidifying bodies 20 and maintains a space|interval may be used.

Here, a structure for suspending the humidifier 20 inside the casing 10 will be described with reference to FIGS. 4, 6 and 7. FIG. FIG. 7 is an enlarged view of the humidifying element 2 shown in FIG. As shown in FIG. 4, the humidifying element 2 includes a plurality of humidifying bodies 20 arranged along the X-axis direction so as to provide a gap therebetween, and a plurality of humidifying bodies 20 extending along the X-axis direction. a diffuser 30 in contact with the upper end of each of the diffusers 30, a water reservoir 12 serving as water supply means for supplying water to the diffuser 30, and a box-shaped casing 10 housing the humidifier 20, the diffuser 30, and the water reservoir 12. Prepare.

As shown in FIG. 6, the water reservoir 12 is formed in a box-like shape with an upward opening. The water reservoir 12 has a first bottom wall 12b and a first side wall 12c extending along the Z-axis direction from the peripheral edge of the first bottom wall 12b. The entire first bottom wall 12 b and a portion of the first side wall 12 c are arranged within the recess 23 . As shown in FIG. 7, each of the first side walls 12c connected to both ends along the Y-axis direction of the first bottom wall 12b has one suspending portion 60 for suspending the humidifier 20. formed one by one. Two hanging portions 60 are formed in the water storage portion 12 in the present embodiment. The suspending portion 60 is a projection extending along the Y-axis direction. Although the shape of the suspending portion 60 is not particularly limited, it is rectangular in this embodiment.

The recess 23 is open upward. The inner wall of the recess 23 has a second bottom wall 23a and second side walls 23b connected to both ends of the second bottom wall 23a along the Y-axis direction. Each of the second side walls 23b is formed with one protrusion 23c that protrudes more than other portions. The protrusion 23c extends toward the water reservoir 12 along the Y-axis direction. A hanging portion 22 held by a hanging portion 60 is formed between the projection 23c and the second bottom wall 23a. Two hanging parts 22 are formed in the humidifier 20 in the present embodiment. The suspended portion 22 is a groove in which the suspended portion 60 is inserted. Although the shape of the suspended portion 22 is not particularly limited, it is rectangular in this embodiment.

The upper surface of the suspending portion 60 and the inner upper wall of the suspended portion 22 are in contact with each other. The humidifier 20 is suspended from the water storage section 12 via the suspension section 60 and the suspended section 22 . The vertical position of the humidifying body 20 is determined by the suspending portion 60 . As shown in FIG. 6, the lower end of the humidifier 20 does not come into contact with other parts. That is, the humidifier 20 is suspended inside the casing 10 with the lower end of the humidifier 20 above the bottom wall 10e of the casing 10 and away from the bottom wall 10e of the casing 10 .

Next, the positional relationship between the humidifier 20 and the diffuser 30 will be described in detail with reference to FIGS. 7 and 8. FIG. 8 is a diagram of the humidifier 20 shown in FIG. 6 before assembly. Hereinafter, the state before assembling the humidifier 20 to the casing 10, the diffuser 30, and the water reservoir 12 is called pre-assembly, and the state after the humidifier 20 is assembled to the casing 10, the diffuser 30, and the water reservoir 12 is called the pre-assembly. Called after assembly. As shown in FIGS. 7 and 8, the portion of the inner wall of the hanging portion 22 of the humidifier 20 that contacts the hanging portion 60 of the water storage portion 12 is a horizontal surface. This horizontal plane is called a first horizontal plane S. In the humidifier 20 before assembly shown in FIG. 8, the portion that comes into contact with the diffuser 30 after assembly shown in FIG. 7 is a horizontal surface. This horizontal plane is called a second horizontal plane T. FIG. A distance along the vertical direction from the first horizontal plane S to the second horizontal plane T is called a first distance A. As shown in FIG. The first horizontal plane S is located above the second horizontal plane T. As shown in FIG.

The portion where the humidifier 20 and the diffuser 30 come into contact after assembly as shown in FIG. 7 is a horizontal surface. This horizontal plane is called a third horizontal plane U. A distance along the vertical direction from the first horizontal plane S to the third horizontal plane U is called a second distance B. FIG. The first horizontal plane S is located above the third horizontal plane U. The first distance A is shorter than the second distance B.

As shown in FIG. 7, the humidifying body 20 is supported by the hanging portion 60 on the first horizontal plane S and hung on the water storage portion 12. Although the position does not change, the weight of the diffuser 30 is applied to the third horizontal plane U, so the vertical position of the third horizontal plane U is lower than the vertical position of the second horizontal plane T. Therefore, since the third horizontal plane U is positioned below the second horizontal plane T, the first distance A is shorter than the second distance B.

The humidifier 20 is provided with two cuts 24 extending downward from the second horizontal plane T. As shown in FIG. The cuts 24 extend obliquely downward away from both ends of the second horizontal plane T along the Y-axis direction. FIG. 9 is a cross-sectional view taken along line IX-IX shown in FIG. 7, showing a contact portion between the humidifier 20 and the diffuser 30. As shown in FIG. Due to the provision of the cuts 24 shown in FIG. 7, when the humidifying body 20 and the diffusing body 30 come into contact with each other, the portion of the humidifying body 20 that is positioned between the two cuts 24 is the same as that shown in FIG. , a bent portion 25 is bent so as to fall down in the X-axis direction. The bent portion 25 acts like a spring. In other words, the elasticity of the bent portion 25 pushes up the diffuser 30 to bring the humidifier 20 and the diffuser 30 into contact with each other more firmly. Note that the cuts 24 may extend directly downward from both ends of the second horizontal plane T along the Y-axis direction, or may approach each other from both ends of the second horizontal plane T along the Y-axis direction. may extend obliquely downward.

Next, the effects of the humidifying element 2 according to this embodiment will be described.

In the present embodiment, as shown in FIG. 6, the humidifier 20 is inserted into the casing 10 with the lower end of the humidifier 20 above the bottom wall 10e of the casing 10 and away from the bottom wall 10e of the casing 10. By being suspended, when the humidifier 20 contains moisture, the lower part of the humidifier 20 is less likely to buckle due to the weight of the moisture. That is, it is possible to suppress buckling of the humidifier 20 when it contains water. In addition, since the humidifier 20, which is a porous material, is suspended in the casing 10 as in the present embodiment, the fibers of the porous material extend and the length of the humidifier 20 along the vertical direction increases. Even when the humidifying body 20 is lengthened, it is possible to suppress the bending of the humidifying body 20 compared to the case where both the upper end portion and the lower end portion of the humidifying body 20 are fixed to other components.

In the present embodiment, as shown in FIG. 7, the humidifying body 20 is supported by the hanging part 60 on the first horizontal plane S and suspended from the water storage part 12. Therefore, the vertical position of the humidifying body 20 is held, the moisture-containing diffuser 30 exerts a downward force on the humidifier 20 due to the weight of the moisture. Therefore, in the third horizontal plane U, the humidifier 20 and the diffuser 30 contact each other so as to press against each other. As a result, the humidifier 20 and the diffuser 30 can be brought into uniform contact with each other, and even when there are a plurality of humidifiers 20, water can be uniformly supplied from the diffuser 30 to each of the plurality of humidifiers 20. can.

If, instead of suspending the humidifier 20 in the casing 10, the lower end of the humidifier 20 is placed on the bottom wall 10e of the casing 10, the humidifier 20 and the diffuser 30 are pressed against each other. When they are brought into contact with each other, the weight of the humidifier 20, the weight of the moisture, and the repulsive force between the humidifier 20 and the diffuser 30 are applied to the lower end of the humidifier 20 when it contains water. As a result, the lower part of the humidifying body 20 is likely to buckle, and the air path formed between the adjacent humidifying bodies 20 is blocked, so that the amount of humidification is reduced compared to the case where the lower part of the humidifying body 20 does not buckle. In this regard, in the present embodiment, the humidifier 20 is suspended in the casing 10 with the lower end of the humidifier 20 above the bottom wall 10e of the casing 10 and away from the bottom wall 10e of the casing 10. The lower part of the humidifying body 20 is less likely to buckle even when the humidifying body 20 and the diffusing body 30 are brought into contact with each other so as to be pressed against each other.

In the present embodiment, as shown in FIG. 7, the humidifier 20 is provided with two cuts 24 extending downward from the second horizontal plane T, thereby separating the humidifier 20 and the diffuser 30. When the humidifiers 20 are brought into contact with each other so as to press against each other, the portion of the humidifier 20 located between the two cuts 24 is bent so as to fall down in the X-axis direction. The elasticity of the bent portion 25 pushes up the diffuser 30 to bring the humidifier 20 and the diffuser 30 into contact with each other more firmly.

In the present embodiment, as shown in FIG. 7, the hanging portion 60 provided in the water storage portion 12 is a projection, and the suspended portion 22 provided in the humidifying body 20 is a groove, so that the hanging portion 60 and the suspended portion 22 are separated. Although the structure in which the humidifier 20 is suspended in the casing 10 by contact with the inner wall has been exemplified, for example, the suspended portion 60 provided in the water storage portion 12 may be a groove, and the suspended portion 22 provided in the humidifier 20 may be a projection. . As such a structure, for example, by configuring the hanging portion 60 shown in FIG. A structure in which the projection 23c is inserted is conceivable. That is, one of the hanging portion 60 and the suspended portion 22 may be a projection, and the other of the hanging portion 60 and the suspended portion 22 may be a groove into which the projection is inserted.

Further, in the present embodiment, the portion where the suspending portion 60 and the inner wall of the suspended portion 22 are in contact with each other is a horizontal surface, but it may be an inclined surface. In addition, in the present embodiment, as shown in FIG. 7, two suspending portions 60 and two suspended portions 22 are provided, but the number of suspending portions 60 and suspended portions 22 is not limited. At least one hanging portion 60 and at least one suspended portion 22 may be provided. However, when a plurality of hanging parts 60 and hanging parts 22 are provided, the hanging parts 60 and hanging parts 60 and hanging parts 60 and 22 are placed on both sides of the center of the humidifying body 20 along the Y-axis direction so that the center of gravity of the humidifying body 20 is stabilized. Preferably, a portion 22 is provided.

In addition, the humidifier 20 is fixed to the water reservoir 12 and suspended in the casing 10 by mechanical connecting means such as screws and bolts, or adhesive such as hot melt, without using protrusions and grooves. However, there is no functional problem. In the case of such a structure, the horizontal surfaces, inclined surfaces, or vertical surfaces of the water reservoir 12 and the humidifying body 20 may be fixed by mechanical connecting means, adhesive, or the like.

FIG. 10 is a cross-sectional view showing a modification of the humidifying element 2 according to the first embodiment. FIG. 11 is a cross-sectional view showing another modification of the humidifying element 2 according to the first embodiment. The configuration for supplying water from the water reservoir 12 to the diffuser 30 is not limited to the configuration shown in FIG. For example, as shown in FIG. 10, there is no functional problem even if the diffuser 30 is inserted into the water injection hole 12a. In this case, the diffuser 30 becomes a water injection part that injects water into the humidifier 20 . Further, as shown in FIG. 11, a structure in which the water in the water storage part 12 is sucked up by the diffuser 30 and the water flows down to the humidifier 20 does not cause any functional problem. In FIG. 11, the diffuser 30 is preferably made of a porous plate thicker than the humidifier 20 . In this way, even when scales are generated inside the diffuser 30, compared to the case where the humidifier 20 directly absorbs the water in the water reservoir 12, the water absorption performance is less likely to deteriorate due to clogging.

FIG. FIG. 14 is a diagram of the humidifier 20 shown in FIG. 12 before assembly. The second embodiment is different from the first embodiment in the positions of the suspending portion 60A and the suspended portion 22A. In addition, in Embodiment 2, the same code|symbol is attached|subjected about the part which overlaps with above-mentioned Embodiment 1, and description is abbreviate|omitted.

As shown in FIG. 13 , each of the first casing 10a and the second casing 10b of the casing 10 is provided with one suspending portion 60A for suspending the humidifier 20 . Two suspension parts 60A are formed in the casing 10 in the present embodiment. 60 A of suspension parts are protrusions extended toward the humidifier|moistener 20 along the Y-axis direction. Although the shape of the suspending portion 60A is not particularly limited, it is rectangular in this embodiment.

One hanging portion 22A held by the hanging portion 60A is formed on each of one end face and the other end face of the humidifying body 20 along the Y-axis direction.
