Hereinafter, the humidifying element, the humidifying device, the air conditioner, and the ventilation device according to the embodiment will be described in detail with reference to the drawings.

Embodiment 1.
FIG. 1 is a configuration diagram of a humidifying device 1 according to the first embodiment. The humidifying device 1 remains without being used for humidification by the humidifying element 2, the water supply pipe 3 connected to a water supply source such as a water supply facility (not shown) and supplying water for humidification to the humidifying element 2, and the humidifying element 2. A drain pipe 4 for discharging water to the outside and a blower 5 for passing an air flow through the humidifying element 2 are provided. Further, the humidifying device 1 includes a control device 6 for operating equipment such as a blower 5 and a water supply valve 3a, and a drain pan 7 for receiving water flowing down inside the humidifying element 2. Air flows in the direction indicated by the white arrow in FIG. Although the blower 5 is incorporated in the ventilation upper side of the humidifying element 2 in the present embodiment, it may be incorporated in the ventilation lower side of the humidifying element 2.

FIG. 2 is a perspective view of the humidifying element 2 included in the humidifying device 1 according to the first embodiment. One or a plurality of humidifying elements 2 are directly installed on the drain pan 7. Although specific illustration is omitted, the ridge corners on both sides of the top structure of each humidifying element 2 are held so as to be removable by a guide rail or the like mounted on the partition wall and the inner wall surface on the front side of the main body box. ing. A water supply system provided with a water supply valve 3a for supplying or shutting off humidifying water is connected to the humidifying element 2, and a drain pipe 4 is connected to the drain pan 7.

The water supply system for supplying humidifying water to the humidifying element 2 includes a water supply pipe 3 for water supply, a water supply valve 3a which is a solenoid valve for adjusting the pressure and flow rate of water supplied to the humidifying element 2, a water supply pipe 3, and a water supply pipe 3. It is equipped with a strainer (not shown) that prevents dust from entering the water supply valve 3a. It is preferable that all the connection portions of the water supply system except the connection portion with the water supply source side are integrated in the drain pan 7.

FIG. 3 is a perspective view of the humidifying element 2 according to the first embodiment. FIG. 4 is an exploded perspective view of the humidifying element 2 according to the first embodiment. FIG. 5 is a front view of the humidifying element 2 according to the first embodiment. FIG. 6 is a cross-sectional view taken along the line VI-VI of the humidifying element 2 shown in FIG. In FIG. 6, hatching is omitted. Hereinafter, the width direction of the humidifying element 2 is the X-axis direction, the depth direction of the humidifying element 2 is the Y-axis direction, and the height direction of the humidifying element 2 is the Z-axis direction. As shown in FIGS. 3 to 5, the humidifying element 2 includes a large number of flat plate-shaped humidifying bodies 20. A large number of humidifiers 20 are arranged with a gap from each other along the X-axis direction. The gap between the adjacent humidifiers 20 becomes an air passage through which air can pass. The blower 5 shown in FIG. 1 generates an air flow from the windward side to the leeward side and allows the air to pass through the gap between the humidifiers 20. Air flows through the gap between the humidifiers 20 from the + side to the-side in the Y-axis direction. As shown in FIG. 4, a recess 23 is formed in the central portion of the upper portion of the humidifying body 20 along the Y-axis direction, which is recessed below the other portions. A diffuser 30 is arranged in the recess 23. The diffuser 30 is arranged so as to extend along the X-axis direction, and the upper ends of the plurality of humidifiers 20 are collectively in contact with one diffuser 30.

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

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

The casing 10 is made of a thermoplastic plastic containing ABS (Acrylonitrile Butadiene Styrene) resin, polystyrene (PS) resin, or polypropylene (PP) resin by injection molding or the like. 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 humidifying body 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 with each other, the first casing 10a and the second casing are used. It is integrated with 10b and has a structure for accommodating the humidifying body 20. The casing 10 may be made of metal or metal and resin as long as it can accommodate the humidifying body 20.

Each of the first casing 10a and the second casing 10b is provided with a portion serving as a drain port 13a. Further, the second casing 10b is provided with a water supply port 11 for supplying water to the water storage unit 12 and an opening 10c for introducing the humidified air into the humidifying body 20. Inside the casing 10, a storage space for accommodating the humidifying body 20 is provided.

Of the first casing 10a and the second casing 10b, the portions of the second casing 10b that come into contact with the humidifying body 20 are provided with positioning protrusions 10d for restricting the horizontal position of the humidifying body 20. Since the humidifier 20 may be deformed by the weight of water due to water content, the horizontal position of the humidifier 20 is restricted by the outer peripheral portion of the humidifier 20 in contact with the first casing 10a and the second casing 10b. By preventing the entire humidifying body 20 from being distorted, it is possible to secure the dimensions of the air passage between the humidifying bodies 20 and allow air to flow uniformly through the air passage between the humidifying bodies 20. 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 the humidifying surface, so that the effect of increasing the humidifying amount can be expected as compared with the case where the humidifying body 20 is distorted. ..

The shape of the water supply port 11 shown in FIG. 2 is a shape that matches the water supply pipe 3, and a convex band, a so-called barb structure, is formed on the outer peripheral surface of the water supply port 11 so as not to easily come off. The water supply pipe 3 may be tied with a hose band. The position of the water supply port 11 is not restricted as long as it has a structure capable of supplying water from the upper part of the humidifying body 20, but considering the case where water leaks from the joint between the water supply pipe 3 and the water supply port 11, the air flow It is preferable to arrange it on the wind side of. By doing so, the water leaking from the joint between the water supply pipe 3 and the water supply port 11 rides on the airflow, is guided to the leeward side, that is, the humidifying element 2, and is absorbed by the humidifying body 20, so that the humidifying element is absorbed. It is possible to reduce the scattering of water to the leeward side of 2.

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. 6, the amount of drainage discharged from the drainage unit 13 without being used for humidification increases, which is wasteful. The amount of water increases. Therefore, it is preferable that the water supply port 11 is provided with a mechanism for reducing the amount of water to adjust the amount of water supplied to the water storage unit 12. The mechanism for reducing the amount of water is, for example, the orifice portion 40. The orifice portion 40 is formed so that a part of the inner peripheral surface of the water supply port 11 is narrower than other portions. The orifice portion 40 may be any as long as the amount of water can be adjusted, and there is no functional problem even if the orifice portion 40 uses a metal mesh or a porous material to adjust the amount of water.

The water storage unit 12 is fixed to the casing 10. Further, the water storage unit 12 is provided above the diffuser 30. On the bottom surface of the water storage portion 12, a plurality of water injection holes 12a, which are water injection portions for injecting water into the diffuser 30, are formed. The water storage unit 12 serves as a 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 unit 12 may be installed inside the water storage unit 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 control device 6 shown in FIG.

The water storage unit 12 is formed by a molding method such as injection molding using a thermoplastic plastic containing ABS resin, PS resin or PP resin as a material. When the surface of the water storage unit 12 is smoothed by using the water storage unit 12 made of resin, the contact angle becomes approximately 90 degrees or more. Here, hydrophobicity has a contact angle of 90 degrees or more, hydrophilicity has a contact angle of 40 degrees or more and less than 90 degrees, and superhydrophilicity has a contact angle of less than 40 degrees. In the present embodiment, the contact angle on the surface of the water storage unit 12 is set to be approximately 90 degrees or more. As a result, the surface of the water storage unit 12 becomes hydrophobic, so that there is an advantage that water is less likely to remain on the surface of the water storage unit 12 and the hygiene inside the water storage unit 12 is improved. The water storage unit 12 only needs to be able to store water and supply water to the humidifying body 20, and even if it is formed of a circular tube, a rectangular tube, or the like, there is no functional problem. Further, the material of the water storage unit 12 may be metal.

The diffuser 30 is formed of a porous plate material. The diffuser 30 is fixed to the water storage unit 12. The diffuser 30 is arranged directly below the water injection hole 12a. The diffuser 30 absorbs the water dropped from the water storage unit 12 and sends the water to the humidifier 20. Therefore, when the surface of the diffuser 30 is as hydrophilic as possible, the permeability becomes good and the flow rate through which water can pass increases. Further, since the diffuser 30 is always in contact with water, it is preferable that the diffuser 30 is made of a material that is not easily deteriorated by water. The diffuser 30 made of a material that is not easily deteriorated by water is made of polyester such as polyethylene terephthalate (PET) resin, a porous plate made of cellulose, and metals titanium, copper, and stainless steel. Examples thereof include the formed porous plate. Further, in order to increase the hydrophilicity of the surface of the diffuser 30, the diffuser 30 may be subjected to a hydrophilic 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 humidifier 20 are in contact with each other, water flows down to the humidifier 20 without stagnation due to the action of the capillary force of the humidifier 20.

The humidifier 20 is formed of a porous plate material like the diffuser 30. The preferred 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 material of 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 sufficiently diffuses into the diffuser 30, so that the humidifier 20 is supplied with water. The uniformity of the water supply may decrease. In this case, measures can be taken by increasing the vertical dimension of the diffuser 30. If there are dimensional restrictions in the height direction of the entire humidifying element 2, the vertical dimensions of the diffuser 30 are also restricted. Therefore, a material having a lower water absorption than the diffusing body 30 is used for the humidifying body 20. Therefore, it is preferable that the vertical dimension of the diffuser 30 can be reduced.

As shown in FIG. 4, a convex portion 21 is provided on the surface of the humidifying body 20. The convex portion 21 keeps the distance between the humidifying bodies 20. The convex portion 21 can be formed by pressing a jig against the humidifying body 20 and plastically deforming the portion to which the jig is pressed. By alternately arranging two types of humidifiers 20 having different arrangement positions of the convex portions 21 on the humidifier 20, a function of keeping the distance between the humidifiers 20 constant can be obtained. It is sufficient that the humidifier 20 is kept constant at intervals along the X-axis direction. For example, a comb having a notch corresponding to the plate thickness of the humidifying body 20 at regular intervals may be engaged with the humidifying body 20 to maintain the space. Further, the structure may be such that the humidifiers 20 formed in a wavy shape are laminated in a honeycomb shape to maintain the interval, or the structure may be such that a spacer is inserted between the humidifiers 20 to maintain the interval.

Here, a structure for suspending the humidifying body 20 in the casing 10 will be described with reference to FIGS. 4, 6 and 7. FIG. 7 is an enlarged view of the humidifying element 2 shown in FIG. As shown in FIG. 4, the humidifying elements 2 include a plurality of humidifying bodies 20 arranged along the X-axis direction so as to provide a gap between them, and a plurality of humidifying bodies 20 extending along the X-axis direction. A diffuser 30 that contacts the upper end of each of the above, a water storage unit 12 that is a water supply means for supplying water to the diffuser 30, and a box-shaped casing 10 that houses the humidifier 20, the diffuser 30, and the water storage unit 12. To prepare for.

As shown in FIG. 6, the water storage unit 12 is formed in a box shape that opens upward. The water storage unit 12 has a first bottom wall 12b and a first side wall 12c extending from the peripheral edge of the first bottom wall 12b along the Z-axis direction. The entire first bottom wall 12b and a part of the first side wall 12c are arranged in the recess 23. As shown in FIG. 7, each of the first side walls 12c connected to both ends of the first bottom wall 12b along the Y-axis direction has one suspension portion 60 for suspending the humidifying body 20. It is formed one by one. In this embodiment, two suspension portions 60 are formed in the water storage portion 12. The suspension portion 60 is a protrusion extending along the Y-axis direction. The shape of the suspension portion 60 is not particularly limited, but is a quadrangle in the present embodiment.

The recess 23 is open upward. The inner wall of the recess 23 has a second bottom wall 23a and a second side wall 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 from the other portion. The protrusion 23c extends toward the water storage portion 12 along the Y-axis direction. A suspended portion 22 held by the suspended portion 60 is formed between the protrusion 23c and the second bottom wall 23a. In this embodiment, two suspended portions 22 are formed on the humidifying body 20. The suspended portion 22 is a groove into which the suspended portion 60 is inserted. The shape of the suspended portion 22 is not particularly limited, but is a quadrangle in the present embodiment.

The upper surface of the suspended portion 60 and the upper wall of the inner wall of the suspended portion 22 are in contact with each other. The humidifying body 20 is suspended from the water storage portion 12 via the suspending portion 60 and the suspended portion 22. The vertical position of the humidifying body 20 is determined by the suspension portion 60. As shown in FIG. 6, the lower end portion of the humidifier 20 is not in contact with other parts. That is, the humidifying body 20 is suspended in the casing 10 with the lower end portion of the humidifying body 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. Note that FIG. 8 is a view before assembling the humidifier 20 shown in FIG. Hereinafter, the state before assembling the humidifier 20 to the casing 10, the diffuser 30, and the water storage unit 12 is referred to as “before assembly”, and the state after assembling the humidifier 20 to the casing 10, the diffuser 30, and the water storage unit 12 is referred to as “before assembly”. Called after assembly. As shown in FIGS. 7 and 8, the portion of the inner wall of the suspended portion 22 of the humidifying body 20 that comes into contact with the suspended portion 60 of the water storage portion 12 is a horizontal plane. This horizontal plane is called the 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 becomes a horizontal plane. This horizontal plane is called a second horizontal plane T. The distance along the vertical direction from the first horizontal plane S to the second horizontal plane T is called the first distance A. The first horizontal plane S is located above the second horizontal plane T.

The portion where the humidifier 20 and the diffuser 30 come into contact with each other after assembly shown in FIG. 7 becomes a horizontal plane. This horizontal plane is called a third horizontal plane U. The distance along the vertical direction from the first horizontal plane S to the third horizontal plane U is referred to as a second distance B. 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, since the humidifying body 20 is supported by the suspension portion 60 by the first horizontal plane S and suspended from the water storage portion 12, the humidifying body 20 is suspended in the vertical direction of the first horizontal plane S before and after assembly. Although the position does not change, the vertical position of the third horizontal plane U is lower than the vertical position of the second horizontal plane T because the weight of the diffuser 30 is added to the third horizontal plane U. Therefore, since the third horizontal plane U is located below the second horizontal plane T, the first distance A is shorter than the second distance B.

The humidifier 20 is provided with two notches 24 extending downward from the second horizontal plane T. The notch 24 extends diagonally downward from both ends of the second horizontal plane T along the Y-axis direction so as to be separated from each other. FIG. 9 is a cross-sectional view taken along the line IX-IX shown in FIG. 7 and is a diagram showing a contact portion between the humidifier 20 and the diffuser 30. Since the notch 24 shown in FIG. 7 is provided, when the humidifying body 20 and the diffuser 30 come into contact with each other, the portion of the humidifying body 20 located between the two notches 24 is shown in FIG. As shown in the above, the bent portion 25 is bent so as to be tilted in the X-axis direction. The bent portion 25 acts like a spring. That is, the elasticity of the bent portion 25 pushes up the diffuser 30 so that the humidifier 20 and the diffuser 30 can be brought into contact with each other even more firmly. The notch 24 may extend directly below 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. It may extend diagonally downward.

Next, the effect of the humidifying element 2 according to the present embodiment will be described.

In the present embodiment, as shown in FIG. 6, the humidifying body 20 is contained in the casing 10 with the lower end portion of the humidifying body 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 humidifying body 20 contains water, the lower part of the humidifying body 20 is less likely to buckle due to the weight of the water. That is, the buckling of the humidifying body 20 at the time of water content can be suppressed. Further, since the humidifying body 20 which is a porous material is suspended in the casing 10 as in the present embodiment, the fibers of the porous material are stretched and the length of the humidifying body 20 along the vertical direction is increased. Even when the length is increased, it is possible to suppress the occurrence of deflection of the humidifying body 20 as compared with the case where both the upper end portion and the lower end portion of the humidifying body 20 are fixed to other parts.

In the present embodiment, as shown in FIG. 7, since the humidifier 20 is supported by the suspension portion 60 on the first horizontal plane S and suspended from the water storage portion 12, the position of the humidifier 20 in the vertical direction is On the other hand, the diffuser 30 containing water exerts a force to lower the humidifier 20 due to the weight of the water. Therefore, in the third horizontal plane U, the humidifier 20 and the diffuser 30 come into contact with each other so as to press 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.

Temporarily, the lower end portion of the humidifying body 20 is placed on the bottom wall 10e of the casing 10 without suspending the humidifying body 20 in the casing 10, and then the humidifying body 20 and the diffuser 30 are pressed against each other. When they are brought into contact with each other, the weight of the humidifying body 20, the weight of the water, and the repulsive force between the humidifying body 20 and the diffuser 30 are applied to the lower end portion of the humidifying body 20 when it is moistened. As a result, the lower part of the humidifying body 20 tends to buckle, and the air passage formed between the adjacent humidifying bodies 20 is blocked, so that the amount of humidification is reduced as compared with the case where the lower part of the humidifying body 20 does not buckle. In this respect, in the present embodiment, the humidifying body 20 is suspended in the casing 10 with the lower end portion of the humidifying body 20 above the bottom wall 10e of the casing 10 and away from the bottom wall 10e of the casing 10. As a result, 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, the lower portion of the humidifying body 20 is less likely to buckle.

In the present embodiment, as shown in FIG. 7, the humidifying body 20 is provided with two notches 24 extending downward from the second horizontal plane T, whereby the humidifying body 20 and the diffuser 30 are provided. When they are brought into contact with each other so as to be pressed against each other, the portion of the humidifying body 20 located between the two notches 24 bends so as to fall in the X-axis direction. Due to the elasticity of the bent portion 25, the diffuser 30 can be pushed up 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 suspension portion 60 provided in the water storage portion 12 is a protrusion, and the suspension portion 22 provided in the humidifying body 20 is a groove, and the suspension portion 60 and the suspension portion 22 are formed. Although the structure in which the humidifying body 20 is suspended in the casing 10 by contact with the inner wall is exemplified, for example, the suspending portion 60 provided in the water storage portion 12 may be a groove, and the suspended portion 22 provided in the humidifying body 20 may be a protrusion. .. As such a structure, for example, by forming the suspension portion 60 shown in FIG. 7 with two protrusions spaced apart from each other in the vertical direction, a groove is formed between the two protrusions to form a groove in the groove. A structure in which the protrusion 23c is inserted can be considered. That is, one of the suspended portion 60 and the suspended portion 22 may be a protrusion, and the other of the suspended portion 60 and the suspended portion 22 may be a groove into which the protrusion can be inserted.

Further, in the present embodiment, the portion where the suspended portion 60 and the inner wall of the suspended portion 22 come into contact with each other is a horizontal plane, but an inclined surface may be used. Further, in the present embodiment, as shown in FIG. 7, two suspension portions 60 and two suspended portions 22 are provided, but the purpose is not to limit the numbers of the suspension portions 60 and the suspended portions 22 respectively. At least one of each of the suspended portion 60 and the suspended portion 22 may be provided. However, when a plurality of the suspending portions 60 and the suspended portions 22 are provided, the suspending portions 60 and the suspended portions are suspended 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 stable. It is preferable to provide the portion 22.

Further, the humidifying body 20 is fixed to the water storage portion 12 and suspended in the casing 10 by, for example, a mechanical connecting means such as a screw or a bolt, or an adhesive such as a hot melt, without using protrusions and grooves. However, there is no functional problem. In the case of such a structure, the horizontal planes of the water storage portion 12 and the humidifying body 20 may be fixed to each other, the inclined surfaces to each other, or the vertical faces to each other by a mechanical connecting means, an adhesive or the like.

FIG. 10 is a cross-sectional view showing a modified example 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 storage unit 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 unit that injects water into the humidifier 20. Further, as shown in FIG. 11, there is no functional problem even if the diffuser 30 sucks up the water in the water storage unit 12 and causes the water to flow down to the humidifier 20. In FIG. 11, the diffuser 30 is preferably formed of a porous plate thicker than the plate thickness of the humidifier 20. By doing so, even when scale is generated inside the diffuser 30, the deterioration of the water absorption performance due to clogging is small as compared with the case where the humidifier 20 directly sucks up the water of the water storage unit 12.

As shown in FIGS. 13 and 14, the portion where the upper wall of the inner wall of the suspended portion 22A of the humidifying body 20 and the suspended portion 60A of the casing 10 come into contact with each other is a horizontal plane. This horizontal plane is called the first horizontal plane S1. In the humidifier 20 before assembly shown in FIG. 14, the portion that comes into contact with the diffuser 30 after assembly shown in FIG. 13 becomes a horizontal plane. This horizontal plane is called the second horizontal plane T1. The distance along the vertical direction from the first horizontal plane S1 to the second horizontal plane T1 is referred to as a first distance A1. The first horizontal plane S1 is located below the second horizontal plane T1.

The portion where the humidifier 20 and the diffuser 30 come into contact with each other after assembly shown in FIG. 13 becomes a horizontal plane. This horizontal plane is called a third horizontal plane U1. The distance along the vertical direction from the first horizontal plane S1 to the third horizontal plane U1 is referred to as a second distance B1. The first horizontal plane S1 is located below the third horizontal plane U1. The first distance A1 is longer than the second distance B1.
