The present invention relates to a humidifying element that generates humidified air, a humidifying device, a ventilator, and an air conditioner.

Humidification methods in humidifying devices that generate humidified air include methods such as a natural evaporation method, an electric heating method, a water spray method, and an ultrasonic method. A natural evaporation type humidifier is useful especially for use in a place where it is operated for a long time because it is easier to reduce the running cost than other types of humidifiers.

There are various forms of natural evaporation humidifiers. Among them, there are a "dripping type" and a "flowing down type" as humidification methods that have little change in humidification capacity over time and are suitable for long-term use. Drip or flow-down humidifiers tend to be used in commercial humidifiers such as air conditioners.

Patent Document 1 discloses a humidifying device that is a flow-down type that sucks up and flows water supply, and prevents clogging due to scale components in the sucking up portion by making the water absorbing portion higher in water absorption than other portions. disclosed.

FIG. 3 is a perspective view of a humidifying element included in the humidifying device according to Embodiment 1. FIG. 4 is an exploded perspective view of a humidifying element included in the humidifying device according to Embodiment 1. FIG. The humidifying element 2 has a water supply mechanism 50 connected to a water supply source and a plurality of flat humidifiers 20 . The humidifier 20 is installed below the water supply mechanism 50 . The humidifier 20 retains the water supplied from the water supply mechanism 50 and humidifies the air flowing on the surface. The water supply mechanism 50 includes a water supply pipe 3 that is connected to a water supply source integrated with water supply equipment and feeds water for humidification to the humidifier 20 , and a water tank 12 to which water is supplied through the water supply pipe 3 . The water supply pipe 3 is provided with a water supply valve 3a, which is a water supply system electromagnetic valve. The water supply valve 3a switches between supplying water for humidification to the water tank 12 and shutting it off. Also, the water supply valve 3 a adjusts the pressure and flow rate of water supplied to the water tank 12 . The water supply mechanism 50 may include a strainer that prevents dust from entering.

The humidifying device 1 includes an intake port 1a for taking in air and an outlet port 1b for discharging air. A blower 5 for sending air into the humidifying element 2 and blowing out the air again is incorporated on the upper or lower side of the ventilation element 2 . FIG. 1 shows a state in which the blower 5 is installed on the airflow side of the humidifying element 2 . The blower 5 forms an airflow that flows in from the intake port 1a and flows out from the discharge port 1b.

The humidifier 1 includes a drain pipe 4 for discharging water remaining without being humidified by the humidifier 20 to the outside.

The drainage part 13 is provided below the humidifying element 2 .

It is preferable that all of the connection portions of the water supply mechanism 50 except for the connection portion with the water supply source side are concentrated above the drain pan 7 .

5 is a front view of a humidifying element included in the humidifying device according to Embodiment 1. FIG. 6 is a cross-sectional view of a humidifying element included in the humidifying device according to Embodiment 1. FIG. FIG. 6 shows a cross section along line VI-VI in FIG. The humidifiers 20 are arranged along a first direction indicated by arrow Y in FIGS. It forms air passages that are continuous in the direction. The humidifier 20 is formed in a plate shape using a hydrophobic material. The airflow generated by the blower 5 flows in the second direction indicated by the arrow Z shown in FIGS. 4 and 6 . That is, in FIG. 6, the airflow flows from the left side to the right side of the drawing. Therefore, in FIG. 6, the left side of the illustrated humidifier 20 is the windward side end face 20a, and the illustrated right side of the humidified body 20 is the leeward side end face 20b. As shown in FIG. 6 , a diffusion member 30 is in contact with the upper portion of the humidifier 20 . The diffusion member 30 is arranged so as to extend along the first direction in which the plurality of humidifiers 20 are arranged, and the humidifiers 20 collectively contact one diffusion member 30 .

As shown in FIG. 4, the humidifier 20 is accommodated and fixed in the casing 10 provided with openings. By sandwiching the humidifying body 20 between the casings 10a and 10b and engaging portions 15 of the casings 10a and 10b together, the casings 10a and 10b are integrated to form a structure that houses the humidifying body 20. In addition, the casing 10 only needs to accommodate the humidifier 20, and may be made of metal, or may be made of metal and plastic. The casing 10a and the casing 10b are each provided with a drain port 13a and an opening 10c for introducing the air to be humidified into the humidifier 20. As shown in FIG.

Further, the casing 10 b is provided with a water supply port 11 for supplying water to the water tank 12 . A housing space for housing the humidifier 20 is provided inside the casing 10 . The casing 10 is formed with a structural wall 14 that connects a water tank 12 as an upper structure and a drainage section 13 as a lower structure.

At least one humidifying element 2 is installed on the drain pan 7 . The ridges on both sides of the top structure of the humidifying element 2 are detachably held by guide rails or the like mounted on the partition wall and the inner wall surface on the front side of the main body box body. Illustrations of the partition wall, the inner wall surface on the front side of the main body box, and the guide rail are omitted.

As shown in FIG. 4 , a water tank 12 for storing water to be supplied to the humidifier 20 is installed above the humidifier 20 . Water is injected into the water tank 12 from the water supply pipe 3 through the water supply port 11 . Here, a series of structures for transmitting water supplied to the humidifying element 2 to the humidifying body 20 is called a water supply mechanism 50 . In the humidifying device 1 according to Embodiment 1, the water supply port 11 , the water tank 12 and the diffusion member 30 constitute the water supply mechanism 50 .

The casing 10 is formed by a molding method such as injection molding using a thermoplastic plastic material including ABS (Acrylonitrile Butadiene Styrene) resin, polystyrene (PolyStyrene: PS) resin, or polypropylene (PolyPropylene: PP) resin.

A portion of the casing 10 that contacts the humidifier 20 is provided with a positioning protrusion that regulates the position of the humidifier 20 . Since the humidifying body 20 softens when it contains water and may deform due to the weight of the water, by restricting the position of the humidifying body 20 at the outer peripheral portion of the humidifying body 20 that contacts the casing 10, the flow between the humidifying bodies 20 is reduced. The dimension of the passage can be secured and the air can flow uniformly.

As a result, the decrease in the pressure loss of the humidifier 20 is suppressed, and the entire surface of the humidifier 20 is effectively used as a humidification surface, so the effect of increasing the amount of humidification can be expected compared to the case where the humidifier 20 is distorted. .

As shown in FIG. 6 , a plurality of water injection holes 12 a are formed in the bottom surface of the water tank 12 for dripping water onto the diffusion member 30 . A water detection sensor 8 for detecting the water level in the water tank 12 may be installed in the water tank 12 . The water tank 12 and the diffusion member 30 are integrally combined, and the integral part is sandwiched and held by the casing 10 . The detected water level may be fed back and the opening and closing of the water supply valve 3a may be controlled by the controller 6 shown in FIG.

The water tank 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. Since the water tank 12 uses a resin material as a material, if the surface is smooth, the contact angle with water is large, approximately 90 degrees or more, and the surface is hydrophobic. Therefore, water hardly remains on the inner surface of the water tank 12, and is excellent in sanitation. 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 addition, the water tank 12 should just store water and supply water to the humidification body 20, and even if it is formed with a circular pipe or a rectangular pipe, there is no functional problem. Also, the material may be metal.

The water supply port 11 is provided above the humidifying element 2 and above the humidifying body 20 in order to supply water to the water tank 12 . The shape of the water supply port 11 is made to match the shape of the water supply pipe 3, and a barb structure may be formed to prevent it from coming off easily, or it 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 arranging the water supply port 11 on the windward side of the air flow, water leaking from the joint between the water supply pipe 3 and the water supply port 11 is carried by the air flow, is guided to the leeward side, and is absorbed by the humidifier 20. Splashing of water to the leeward side of the humidifier 20 can be reduced.

If the amount of water supplied is excessive relative to the amount of humidification, the amount of water that flows out from the drainage part 13 without being humidified and is wasted increases. It is preferable to adjust the amount of water supplied to. In the humidifying device 1 according to Embodiment 1, the mechanism for restricting the amount of water supplied to the water tank 12 is the orifice section 40 shown in FIG. When adjusting the amount of water, it is necessary to supply a larger amount of water than the maximum amount of humidification of the humidifier 20. - 特許庁It should be noted that the orifice part 40 only needs to be capable of adjusting the flow rate, and there is no functional problem with using a metal mesh or a porous material to adjust the amount of water.

FIG. 7 is a diagram showing a first modification of the water supply mechanism included in the humidifying device according to Embodiment 1. FIG. FIG. 8 is a diagram showing a second modification of the water supply mechanism included in the humidifying device according to Embodiment 1. FIG. The water supply mechanism 50 only needs to supply water to the humidifier 20, and there is no functional problem even if the diffusion member 30 is inserted inside the water injection hole 12a as shown in FIG. Alternatively, as shown in FIG. 8, by extending the diffusion member 30 inside the water tank 12, there is no functional problem with a structure in which the water is sucked up and drained. Alternatively, the water tank 12 may be formed as a watertight header portion (not shown), and water may be dripped onto the diffusion member 30 from a plurality of water injection holes 12a formed in the header.

The diffusion member 30 is made of a porous plate material. Since the diffusing member 30 absorbs the water dropped from the water tank 12 and sends the water to the humidifier 20, the surface of the material should be as hydrophilic as possible to improve permeability and increase the flow rate of water flow. Moreover, since the diffusion member 30 is always in contact with water, it is preferable that the diffusion member 30 be made of a material that is not easily deteriorated by water. Examples of materials that are less likely to be degraded by water include polyester such as polyethylene terephthalate (PET) resin, cellulose, and metals such as titanium, copper, and stainless steel. In addition, the diffusion member 30 may be subjected to hydrophilization treatment in order to increase the hydrophilicity of the surface of the material.

The lower end of the diffusion member 30 and the upper end of the humidifier 20 are placed in contact with each other. If the diffusion member 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 . In consideration of variations during assembly of the diffusion member 30 and the humidifier 20 and the influence of vibration during transportation, the diffusion member 30 and the humidifier 20 are placed such that the lower end of the diffusion member 30 and the upper end of the humidifier 20 are inserted into each other. may be concatenated with

The diffusion member 30 is provided to evenly diffuse the water dripping from the water tank 12 located above in the first direction. That is, the diffusion member 30 is provided to uniformly supply water to the plurality of humidifiers 20 arranged side by side in the first direction. Therefore, when a plurality of humidifying bodies 20 are integrated and water can be diffused in the first direction between the plurality of humidifying bodies 20, or the upper part of the humidifying body 20 is bent and the adjacent humidifying bodies 20 are brought into contact with each other In this case, the humidifier 20 itself has the same water diffusion function as the diffusion member 30 does. In this case, instead of the diffusion member 30 shown in FIG. It can also extend inside the tank 12 . In these cases, water can flow directly from the water tank 12 to the humidifier 20 without using the diffusing member 30, which is advantageous in that the water supply mechanism 50 can be formed at a relatively low cost.

The humidifier 20 is made of a porous plate like the diffusion member 30 . Suitable conditions for the material of the humidifier 20 are the same as those of the diffusion member 30 , and the same material as the diffusion member 30 may be used as the material of the humidifier 20 . However, if a material having higher water absorption than the diffusion member 30 is used for the humidifier 20 , the humidifier 20 absorbs water before the water diffuses inside the diffusion member 30 . supply uniformity may be reduced. In this case, a countermeasure can be taken by increasing the vertical dimension of the diffusion member 30 . If there is a restriction on the height of the entire humidifying body 20, the vertical dimension of the diffusion member 30 is also restricted. is preferably used to reduce the vertical dimension of the diffusion member 30 .

A convex portion 21 is provided on the surface of the humidifier 20 . 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, the humidifier 20 only needs to have a constant interval between the humidifiers 20 along the first direction. The space may be maintained by meshing with the body 20, or the structure may be such that the space is maintained by laminating the corrugated humidifying bodies 20 in a honeycomb shape. Moreover, the structure which puts a spacer between the humidifying bodies 20 and maintains a space|interval may be sufficient.

On the surfaces of the humidifiers 20 , the air is humidified due to the water vapor partial pressure difference between the air flowing between the humidifiers 20 and the water retained in the humidifiers 20 . The amount of humidification in the direction of air flow is greater on the windward side and smaller on the leeward side. This is because the water vapor partial pressure difference is large on the windward side, and the wind separates at the windward end surface 20a of the humidifying body 20 to promote humidification. Therefore, the amount of humidification at the end on the windward side end face 20a side is greater than the humidification amount at the portion other than the end portion of the windward side end face 20a of the humidifier 20 .

9 is a cross-sectional view of a humidifier included in the humidifier according to Embodiment 1. FIG. FIG. 9 shows a cross section along line IX-IX in FIG. The humidifying body 20 has a uniform density, but the plate thickness of the humidifying body 20 at the windward end face 20a is thicker than the plate thickness of the humidifying body 20 at portions other than the windward end face 20a. When the humidifying body 20 has a thin portion 202 and a thick portion 201 with the same density, the portion 201 with the thick thickness retains more water than the portion 202 with the thin thickness. Since the plate thickness of the humidifying body 20 on the windward end face 20a is thicker than the plate thickness of the humidifying body 20 on the part other than the windward end face 20a, compared to the case where the plate thickness is uniform, the inside of the humidifying body 20 A large amount of water flowing through is allowed to flow to the windward end surface 20a. Therefore, the humidifying body 20 has a low resistance portion at the end on the windward end face 20a side, which has a lower water flow resistance than the part other than the end on the windward end face 20a side.

The water contained in the humidifier 20 contains scale components such as calcium. Therefore, when the water evaporates from the humidifier 20 , scale components are deposited and remain on the surface of the humidifier 20 . When the supplied water is uniform, as described above, the end on the windward end face 20a side dries easily due to a larger amount of evaporation than the end on the windward end face 20a side. Ingredients are easy to precipitate. Alternatively, if the amount of water supplied to the humidifying body 20 is increased so as not to generate scale components on the windward end face 20a, the amount of water that flows down without being evaporated on the leeward side and is discarded increases.

The humidifying body 20 included in the humidifying device 1 according to Embodiment 1 allows a large amount of water to flow to the end on the windward end face 20a side where the amount of evaporation is large. It is possible to prevent the precipitation of scale components at the end of the.

In addition, the humidifier 20 only needs to supply a large amount of water to the windward end face 20a, and the thick portion 201 does not necessarily have to be provided at the end of the windward end face 20a. For example, there may be a part 201 with a thick plate thickness somewhere on the windward side of the center between the windward end face 20a and the leeward end face 20b of the humidifier 20 . However, in this case, it is preferable to provide the thick portion 201 as close to the windward end surface 20a as possible.

FIG. 10 is a diagram showing a modification of the humidifying body included in the humidifying device according to Embodiment 1. FIG. The humidifying body 20 according to the modification has a thickness that is continuously reduced from the windward end face 20a toward the leeward tip 20c. The humidifying body 20 according to the modified example is excellent in that the surface unevenness is small and the pressure loss between the humidifying bodies 20 is small.

As described above, the humidifying device 1 according to the first embodiment retains a large amount of water on the windward end surface 20a side due to changes in plate thickness or density, and supplies a large amount of water for evaporation. By suppressing the adhesion of components and preventing deterioration of humidification performance, it is possible to obtain the effect of having stable humidification performance for a long period of time.

Embodiment 2.
FIG. 11 is a cross-sectional view of a humidifying body included in a humidifying device according to Embodiment 2 of the present invention. The humidifying element 2 according to Embodiment 2 has the same configuration as the humidifying element 2 according to Embodiment 1, except that the shape and density of the humidifying body 20 are different. do.

In the humidifying element 2 according to Embodiment 2, the humidifying body 20 is formed of a porous plate material and has a uniform plate thickness. It is lower than the density of the humidifying body 20 in parts other than the end surface 20a. It should be noted that the density of the humidifier 20 made of a porous material decreases as the porosity increases. When the humidifying body 20 has a low-density portion and a high-density portion with the same plate thickness, the low-density portion has low flow resistance, so more water flows than the high-density portion. Therefore, the humidifying body 20 has a low resistance portion at the end on the windward end face 20a side, which has a lower water flow resistance than the part other than the end on the windward end face 20a side. Furthermore, since the low-density portion has many voids, it can retain a large amount of water. Since the density of the humidifier 20 at the end on the windward end face 20a side is lower than the density of the humidifier 20 at a portion other than the end on the windward end face 20a side, the water flowing inside the humidifier 20 is transferred to the windward side. A large amount of water for evaporation can be supplied by allowing a large amount of water to flow toward the end face 20a and to retain the water.

Embodiment 3.
FIG. 12 is a cross-sectional view of a humidifier included in a humidifier according to Embodiment 3 of the present invention. In the humidifying element 2 according to Embodiment 3, the density of the humidifiers 20 at the end on the windward end face 20a side is lower than the density of the humidifiers 20 at the part other than the end on the windward end face 20a side. However, the thickness of the humidifier 20 at the end on the windward end face 20a side is greater than the plate thickness of the humidifier 20 at a portion other than the end on the windward end face 20a side. It's getting thicker. Therefore, the humidifying body 20 has a low resistance portion at the end on the windward end face 20a side, which has a lower water flow resistance than the part other than the end on the windward end face 20a side. The humidifying element 2 according to Embodiment 3 can allow more water to flow toward the windward end surface 20a inside the humidifying body 20 .

Embodiment 4.
FIG. 13 is an enlarged view of a humidifier and a diffusion member in a humidifier according to Embodiment 4 of the present invention. The humidifying element 2 according to Embodiment 4 has the same configuration as the humidifying element 2 according to Embodiment 1 except that the structure of the humidifying body 20 is different.

In the humidifying element 2 according to Embodiment 4, the humidifying body 20 has a thick portion 201 and a thin portion 202 . The thick portion 201 is a low-resistance portion with low water flow resistance, and the thin portion 202 is a high-resistance portion with high water flow resistance. A boundary between the thick portion 201 and the thin portion 202 is inclined so as to be lowered from the leeward side to the windward side. The boundary between the thick portion 201 and the thin portion 202 is lowered from the leeward side to the windward side, so that when water flows downward from above, that is, from the thick portion 201 to the thin portion 202, water flows. When the water flows, the portion 202 with the thin plate becomes a bottleneck, and the water tries to flow toward the portion 201 with the thick plate. That is, inside the humidifier 20, a large amount of water can flow toward the windward end surface 20a.

Thick portions 201 and thin portions 202 are alternately formed. By forming the humidifying body 20 in this way, there are more chances for water to flow from the thick part 201 to the thin part 202. can be done. In the humidifier 20, it suffices to increase opportunities for water to flow from the thick portion 201 to the thin portion 202, and there is no functional problem even if the thickness is formed so as to gradually decrease in the direction of water flow. However, even in this case, the boundary between the thick portion 201 and the thin portion 202 must be inclined so as to become lower from the leeward side toward the windward side.

Embodiment 5.
14 is an enlarged view of a humidifying body and a diffusion member of a humidifying device according to Embodiment 5 of the present invention. FIG. The humidifying element 2 according to Embodiment 5 has the same configuration as the humidifying element 2 according to Embodiment 3, except that the structure of the humidifying body 20 is different.

In the humidifying element 2 according to Embodiment 5, the humidifying body 20 has a low density portion 203 and a high density portion 204 . The low-density portion 203 is a low-resistance portion with low water flow resistance, and the high-density portion 204 is a high-resistance portion with high water flow resistance. The boundary between the low-density portion 203 and the high-density portion 204 slopes down from the leeward side to the windward side. When the water flows from the low-density portion 203 to the high-density portion 204, the boundary between the low-density portion 203 and the high-density portion 204 is inclined downward from the leeward side to the windward side. The high density area 204 becomes a bottleneck and water tries to flow toward the low density area 203 . That is, inside the humidifier 20, a large amount of water can flow toward the windward end surface 20a.

The low-density portions 203 and the high-density portions 204 are alternately formed. By forming the humidifying body 20 in this way, the opportunity for water to flow from the low-density portion 203 to the high-density portion 204 increases, so more water flows inside the humidifying body 20 toward the windward end face 20a. can flow. In addition, in the humidifying body 20, it is sufficient to increase the opportunities for water to flow from the low-density portion 203 to the high-density portion 204, and even if the density is formed so that the density increases sequentially in the water flow direction, there is a problem in terms of function. do not have. However, even in this case, the boundary between the low-density portion 203 and the high-density portion 204 must be inclined so as to be lowered from the leeward side to the windward side.

The processing for adjusting the plate thickness or density for each part can be performed by pressing or rolling the humidifying body 20 . In addition, the plate thickness or density may be changed in advance in the material manufacturing process of the humidifying body 20 .

The air that has passed through the heat exchanger 303 is humidified by the humidifier 1 after flowing into the inlet 1 a of the humidifier 1 . The humidified external OD air is discharged from the discharge port 1b to the outside of the humidifier 1, and is supplied from the air discharge port 307 to the indoor ID. If the air that has passed through the heat exchanger 303 does not need to be humidified, the switch 306 directs the air that has passed through the heat exchanger 303 to the passage 308 . The air that has passed through the heat exchanger 303 passes through the passage 308 and then is supplied from the air outlet 307 to the indoor ID. Thus, the air conditioner 300 can humidify the outside OD air and supply it to the indoor ID of the house 250 . Further, when humidification is not required, the air conditioner 300 can supply the air that has passed through the heat exchanger 303 to the indoor ID without humidification.

In the above description, an example in which the ventilation device 200 and the air conditioner 300 are provided with the humidifying device 1 according to Embodiment 1 has been described. The humidifying device 1 using the humidifying element 2 according to any one of the modes 4 may be provided.

The configuration shown in the above embodiment shows an example of the content of the present invention, and it is possible to combine it with another known technology, and one configuration can be used without departing from the scope of the present invention. It is also possible to omit or change the part.
