Description

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

Humidification methods for humidifiers that generate humidified air include natural evaporation method, electric heating method, water spray method, and ultrasonic method. The natural evaporation type tends to have a smaller humidification capacity than other methods. The electrothermal type tends to have a higher running cost than other types. The water spray type has a lower humidification efficiency than other methods and tends to have a larger size. The ultrasonic type tends to have a higher initial cost than other types. In addition, the ultrasonic type has a short device life and tends to scatter various bacteria in water and calcium carbonate fine powder.

Under these circumstances, the natural evaporation type humidifier is particularly useful for use in a place where it is operated for a long time, because the running cost is easily suppressed as compared with other methods. Further, the humidifying ability, which is the above-mentioned problem, is being improved.

There are various types of natural evaporation type humidifiers. Among them, there is a "dripping type" as a humidifying method suitable for long-term use, in which there is little change in the humidifying ability with time. Drop-type humidifiers tend to be used in commercial humidifiers such as air conditioners.

As a humidifier using a drip-type humidification method, in Patent Document 1, water is supplied to a humidifier from a water storage tank having a plurality of holes on the bottom surface, and water overflowing from the water storage tank is directly passed through an overflow pipe. A drainage arrangement is disclosed.

Japanese Utility Model Publication No. 61-49230

However, according to the technique disclosed in Patent Document 1, when the hole provided on the bottom surface of the water storage tank is blocked by impurities in the water, the water overflowing from the water storage tank is directly drained through the overflow pipe. Therefore, it is not possible to sufficiently exert the merit of the dropping-type humidifying device that it can withstand long-time use by supplying a larger amount of water than the amount to be humidified to the humidifying body to wash off the surface. , There was a problem.

In addition, in the technique of Patent Document 1, it is conceivable that the outlet of the overflow pipe is provided directly above the humidifying body in order to cause the water overflowing from the water storage tank to flow into the humidifying body and be used for humidification. However, in the technique of Patent Document 1, even if a constant flow rate of water is supplied to the water tank, when the hole provided in the bottom surface of the water tank is blocked by impurities in the water, the water overflowing from the water tank and flowing through the overflow pipe is , It becomes an intermittent flow of water. That is, even if a constant amount of water is supplied to the water tank, the water that is about to overflow from the water tank does not immediately flow into the overflow pipe, and the capacity of the water tank exceeds the capacity of the water tank due to surface tension at the edge of the inlet of the overflow pipe. The phenomenon in which the water overflows from the water tank to the overflow pipe at a moment when the water has accumulated to the limit and cannot be controlled by the surface tension is repeated.

In the drip-type humidifying element, when water flows intermittently in the humidifying body, the amount of water absorbed by the humidifying body is reduced as compared with the case where a constant flow rate of water continuously flows, and the humidifying performance may deteriorate. there were.

The present invention has been made in view of the above, and prevents deterioration of the humidifying body by preventing the deterioration of the humidifying body by using the effect of washing away the water supplied to the humidifying element, and the humidifying performance is stable for a long period of time. The purpose is to obtain a humidifying element having.

In order to solve the above-mentioned problems and achieve the object, the humidifying element according to the present invention is provided with a plurality of humidifying bodies arranged so as to provide a gap between each other and above the plurality of humidifying bodies. A diffusing member that is in contact with the plurality of humidifiers, and a water storage tank that is provided above the humidifiers and has a water storage portion that stores water and has a plurality of water injection holes formed on the bottom surface. Inside the water tank, a tubular water conduit extending vertically is provided at a position avoiding the water injection hole, and the lower end of the water conduit serves as an outflow port penetrating the bottom surface of the water reservoir. An inlet is provided in the water conduit at a position lower than the outer wall of the water storage section. A groove-shaped water conduit is formed at a position adjacent to the lowermost end of the inflow port of the water conduit, from the water reservoir side to the inside of the water conduit. The water conduit is inclined downward from the water reservoir side toward the inside of the water conduit .

The humidifying element according to the present invention has an effect of preventing deterioration of the humidifying body and preventing deterioration of the humidifying performance by utilizing the effect of washing away the feed water supplied to the humidifying element, and having stable humidifying performance for a long period of time. ..

Hereinafter, a humidification element, a humidification device, an air conditioner, and a ventilation device according to embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

Embodiment 1.
FIG. 1 is a configuration diagram of a humidifying device 1 according to the first exemplary embodiment of the present invention. A humidifying element 2 is incorporated in the humidifier 1. A blower 5 for feeding the air in the room to the humidifying element 2 and blowing the air into the room again is installed on the upwind side or the downwind side of the humidifying element 2. FIG. 1 shows a state in which the blower 5 is incorporated on the ventilation side of the humidifying element 2.

The humidifying device 1 includes a humidifying element 2, a water supply pipe 3 that is connected to a water supply source such as a water supply facility and supplies the humidifying element 2 with water for humidification, and the water remaining without being humidified by the humidifying element 2 to the outside. A drain pipe 4 for discharging and a blower 5 for allowing an air flow to pass through the humidifying element 2 are provided. The humidifying device 1 also includes a control device 6 that operates devices such as the blower 5 and a water supply valve 3a that is a solenoid valve of a water supply system, and a drain pan 7 that receives drainage and discharges it to the outside.

FIG. 2 is an enlarged view of the humidifying element 2 included in the humidifying device 1 according to the first embodiment. One or more humidifying elements 2 are directly installed on the drain pan 7. The ridge corners on both sides of the top structure of each humidifying element 2 are retained by guide rails mounted on the partition wall and the inner wall surface on the front side of the main body box so as to be removable. Illustration of the partition wall, the inner wall surface on the front side of the main body box, and the guide rail is omitted. A water supply system including a water supply valve 3a for supplying or shutting off water for humidification is connected to the humidification element 2, and a drain pipe 4 is connected to the drain pan 7.

The water supply system for supplying water for humidification to the humidification element 2 includes a water supply valve 3a for adjusting the pressure and flow rate of the water supplied to the humidification element 2, a strainer for preventing dust from entering the water supply system, and a water supply for water supply. It is configured as a water channel including the pipe 3. It is preferable that all the connection parts of the water supply system except the connection part 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 sectional view taken along line VI-VI of the humidifying element 2 shown in FIG. The humidifying element 2 includes a large number of flat plate-like humidifiers 20 arranged along a first direction, which is a direction indicated by an arrow X in FIGS. 4 and 5, so as to provide a gap between them. As shown in FIG. 6, the 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, and the plurality of humidifiers 20 collectively contact one diffusion member 30.

As shown in FIG. 6, above the humidifying body 20, there are a water storage tank 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 tank 12. Further, below the humidifying body 20, there is a drainage section 13 for receiving and draining the water left unhumidified from the humidifying body 20 and a drain port 13a. The humidifier 20 is housed and fixed inside the casing 10. Details of the water storage tank 12 will be described later.

As shown in FIGS. 3 and 4, 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 the water storage tank 12 as an upper structure and the drainage portion 13 as a lower structure.

The casing 10 is formed by a molding method such as injection molding using a thermoplastic resin containing an ABS (Acrylonitrile Butadiene Styrene) resin, a polystyrene (polystyrene:PS) resin, or a polypropylene (PP) resin. The casing 10 is divided into two parts, a casing 10a and a casing 10b. The humidifying body 20 is sandwiched between the casing 10a and the casing 10b, and the engaging portions 15 of the casing 10a and the casing 10b are combined to form a structure in which the casing 10a and the casing 10b are integrated.

Each of the casing 10a and the casing 10b is provided with a portion serving as a drainage port 13a and an opening 10c for introducing humidified air into the humidifying body 20. Further, the casing 10b is provided with a water supply port 11 for supplying water to the water storage tank 12. A storage space for storing the humidifying body 20 is provided inside the casing 10.

A positioning protrusion 10 d for regulating the position of the humidifying body 20 is provided in a portion of the casing 10 that contacts the humidifying body 20. Since some of the humidifiers 20 are softened when they contain water and are deformed by the weight of water, by restricting the position of the humidifiers 20 at the outer peripheral portion of the humidifiers 20 that comes into contact with the casing 10, the flow between the humidifiers 20 is reduced. The size of the passage can be ensured and the air can flow evenly.

As a result, the decrease in 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. Therefore, the effect of increasing the humidifying amount can be expected as compared with the case where the humidifying body 20 is distorted. ..

Since the water supply port 11 supplies water to the water tank 12, the water supply port 11 is provided above the humidifying element 20 and above the humidifying element 2. The shape of the water supply port 11 may be a shape adapted to the water supply pipe 3, and a convex band, a so-called barb structure may be formed so as not to come off easily, or may be bound with a hose band. The water supply port 11 is not limited in position and the like 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 leakage occurs 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 windward side. 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 side, and is absorbed by the humidifying element 20, so that the humidifying element 20 is absorbed. It is possible to reduce the scattering of water to the leeward side of No. 2.

When the amount of water supply is excessive with respect to the amount of humidification, the amount of water that flows from the drainage section 13 increases without being humidified, and the amount of wasted water increases. Therefore, the water supply port 11 is provided with a mechanism for reducing the amount of water. Therefore, it is preferable to adjust the amount of water supplied to the water storage tank 12. The mechanism for reducing the amount of water is, for example, 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 humidifying element 2. The orifice 40 need only be capable of adjusting the flow rate, and a metal mesh or porous material that adjusts the amount of water does not pose any functional problem.

As shown in FIG. 6, the water storage tank 12 is provided above the diffusion member 30. A plurality of water injection holes 12 a for dropping water to the diffusion member 30 are formed on the bottom surface of the water storage tank 12. The water tank 12 and the diffusing member 30 are combined as an integral part, and the integral part is sandwiched and held between the casing 10a and the casing 10b. Further, a water level detection sensor 8 for detecting the water level of the water storage tank 12 may be installed in the water storage tank 12. The detected water level may be fed back to control the opening/closing of the water supply valve 3a by the control device 6 shown in FIG.

The water storage tank 12 is formed of a thermoplastic resin containing ABS resin, PS resin, or PP resin by a molding method such as injection molding. Since the water storage tank 12 uses a resin material as a material, if the surface is smooth, the contact angle in water is large, about 90 degrees or more, and the surface is hydrophobic. Therefore, in the water storage tank 12, water is unlikely to remain on the inner surface, and is excellent in hygiene. Here, the contact angle is 90° or more for hydrophobic, the contact angle is 40° or more and less than 90° for hydrophilic, and the contact angle is less than 40° for superhydrophilic.

The diffusion member 30 is formed of a porous plate material. Since the water dropped from the water storage tank 12 is absorbed and the water is sent to the humidifier 20, the higher the hydrophilicity of the surface of the material is, the better the permeability is and the more the flow rate of water can be increased. Further, since the diffusing member 30 is always in contact with water, it is preferable that the diffusing member 30 is formed of a material that is not easily deteriorated by water. The diffusion member 30 formed of a material that is not easily deteriorated by water includes a porous plate made of polyester such as polyethylene terephthalate (PET) resin, which is a resin, or cellulose, or a metal such as titanium or copper, An example is a porous plate made of stainless steel. Further, in order to increase the hydrophilicity of the surface of the material, the diffusing member 30 may be subjected to a hydrophilic treatment.

The humidifier 20 is formed of a porous plate material like the diffusion member 30. Suitable conditions for the material of the humidifying body 20 are the same as those of the diffusing member 30, and the same material as the diffusing member 30 may be used for the material of the humidifying body 20. However, if a material having better water absorption than the diffusing member 30 is used for the humidifying body 20, the humidifying body 20 absorbs water before the water is sufficiently diffused inside the diffusing member 30, so that the moisture to each humidifying body 20 is absorbed. May be less uniform in supply. In this case, the measure can be taken by increasing the vertical dimension of the diffusion member 30. If the dimension of the humidifying element 2 is limited in the height direction, the dimension of the diffusing member 30 in the vertical direction is also limited. Therefore, a material having lower water absorption than the diffusing member 30 is used for the humidifying body 20. Therefore, it is preferable that the vertical dimension of the diffusion member 30 can be reduced.

A convex portion 21 is provided on the surface of the humidifier 20. By the convex portion 21, the space between the humidifying bodies 20 is maintained. The convex portion 21 can be formed by pressing a jig on the humidifier 20 and plastically deforming the portion pressed by the jig. By alternately arranging the two types of humidifiers 20 in which the convex portions 21 on the humidifier 20 are arranged at different positions, a function of keeping the interval between the humidifiers 20 constant can be obtained. In addition, the humidifier 20 only needs to have a constant interval along the first direction, and a comb having a water conduit for the plate thickness of the humidifier 20 is meshed with the humidifier 20 at regular intervals. The space may be maintained, or the moisturizing body 20 formed in a wave shape may be stacked in a honeycomb shape to hold the space.

The lower end of the diffusing member 30 and the upper end of the humidifying body 20 are installed so as to be in contact with each other. If the diffusing member 30 and the humidifying body 20 are in contact with each other, the water flows down to the humidifying body 20 without stagnation due to the action of the capillary force of the humidifying body 20. The diffusion member 30 and the humidifying body 20 are inserted so that the lower end of the diffusing member 30 and the upper end of the humidifying body 20 are inserted into each other in consideration of the variation in assembling the diffusing member 30 and the humidifying body 20 and the influence of vibration during transportation. And may be connected.

The diffusing member 30 diffuses the water dropped from the water storage tank 12 located above in the first direction evenly, that is, the water is evenly distributed to the plurality of humidifiers 20 arranged side by side in the first direction. Is provided to supply. Therefore, when the plurality of humidifiers 20 are integrated and water can be diffused between the plurality of humidifiers 20 in the first direction, the humidifier 20 itself has a water diffusion function similar to that of the diffusion member 30. Will have. In this case, the water may be dropped directly from the water storage tank 12 to the humidifier 20 without using the diffusion member 30.

Next, the structure of the water storage tank 12 will be described in detail. FIG. 7 is a cross-sectional view taken along the line VII-VII of the humidifying element 2 shown in FIG. 6 and is an enlarged view of the water storage tank 12. A plurality of water injection holes 12 a are formed on the bottom surface of the water storage tank 12. The plurality of water injection holes 12a are in the same plane and are formed so that all the water injection holes 12a are arranged horizontally when the humidifying device 1 and the humidification element 2 are horizontally installed. On the bottom surface 12d of the water storage tank 12, a cylindrical wall surface 12b extending downward from the water injection hole 12a portion is formed. The tip of the cylindrical wall surface 12b contacts the diffusion member 30. A space corresponding to the height of the cylindrical wall surface 12b is provided between the upper surface of the diffusion member 30 and the bottom surface 12d of the water storage tank 12.

8: is the figure which expanded the water injection hole 12a part of the water storage tank 12 in Embodiment 1, and is the figure which looked at the water storage tank 12 from lower direction. FIG. 9 is a sectional view showing an example of the peripheral portion of water storage tank 12 in the first embodiment. A part of the distal end portion of the cylindrical wall surface 12b is notched, and a notch 12c is formed. FIG. 10 is a top view of water storage tank 12 in the first embodiment. FIG. 11 is an enlarged perspective view of the vicinity of the communication channel 120 located on the right side of the water storage tank 12 shown in FIG. 10 in the first embodiment. As shown in FIGS. 10 and 11, a water conduit 123 is provided in a part of the inflow port 121. In addition, the shape shown by the broken line in FIG. 11 represents the shape of the inflow port 121 when the water conduit 123 is not provided.

As shown in FIG. 7, a tubular water guiding pipe 111 extending vertically is provided inside the water storage tank 12 at a position avoiding the water injection hole 12a, that is, extending from the water storage tank 12 toward the diffusion member 30. As a result, the communication channel 120 is formed. That is, the inside of the water conduit 111 serves as the communication channel 120. The communication flow path 120 is a flow path for guiding the water 50 overflowing from the water storage unit 110 to the humidifier 20 via the diffusion member 30. Therefore, the water storage tank 12 guides the water storage unit 110 that stores the water 50 to be supplied to the diffusion member 30 via the water injection hole 12a and the cylindrical wall surface 12b and the water overflowing from the water storage unit 110 to the diffusion member 30. And a communication flow path 120 that communicates with the water storage unit 110.

In the first embodiment, the shape of the water conduit 111 is a rectangular tube shape. The water storage section 110 and the communication channel 120 are partitioned by a partition wall 12f. The partition wall 12f is connected to the inner surface of the outer wall 12e of the water storage tank 12 and is provided in a U shape inside the rectangular region surrounded by the outer wall 12e of the water storage tank 12 in a top view. That is, the water storage unit 110 is a region surrounded by the outer wall 12e of the water storage tank 12 and the partition wall 12f, and has a quadrangular shape in a top view. Therefore, the water conduit 111 is constituted by the outer wall 12e that constitutes the short side of the rectangular shape of the water storage tank 12 and the partition wall 12f. The upper surface of the partition wall 12f is formed so as to be horizontal when the humidifying device 1 and the humidifying element 2 are horizontally installed.

As shown in FIG. 7, in the communication channel 120, an inflow port 121 that is an inlet through which water flows from the water storage unit 110 to the communication channel 120 and an outflow port 122 that is an outlet of the communication channel 120 are formed. Has been done. In the first embodiment, the lower end of the water conduit 111 serves as the outlet 122 that penetrates the bottom surface of the water storage tank 12.

The inflow port 121 is formed at a position lower than the upper end of the water storage part 110, that is, the upper end of the outer wall 12e, so that the water overflowing from the water storage part 110 of the water storage tank 12 is introduced into the communication flow path 120. That is, in the first embodiment, the upper end of the water conduit 111 is located lower than the upper end of the outer wall of the water reservoir 110, and the opening on the upper end side serves as the inflow port 121. When the upper end of the water conduit 111 is higher than the upper end of the outer wall of the water storage section 110, an opening may be provided at a position lower than the outer wall of the water storage section 110 to serve as an inlet.

The water in the water storage section 110 flows in the communication flow path 120 only when it gets over the lowermost portion of the inflow port 121. The arrow in FIG. 7 indicates the direction in which water flows from the water storage unit 110 into the communication channel 120. The inlet 121 and the upper surface 123a of the partition wall are located at a position higher than the upper end of the water injection hole 12a and the water tank 12 is horizontally installed so that the water does not flow into the communication channel 120 until the water overflows from the water reservoir 110. In this state, when a prescribed amount of water is supplied into the water storage unit 110, the water is supplied above the water level where the dropping flow rate of the water injection hole 12a and the supply flow rate to the water storage unit 110 are balanced and balanced. The water level at which the dropping flow rate and the supply flow rate are balanced and balanced will be described later.

Hereinafter, the shape of the water conduit 123 will be described in detail with reference to points a, b, c, d, e, f, g, and h shown in FIG. 11. The water conduit 123 is provided at a corner of the upper surface of the water conduit 111 on the side of the water reservoir 110. The water conduit 123 is composed of a surface formed by connecting points b, d, e, and f, and a surface formed by connecting points c, d, e, and g, It is a V-shaped groove. That is, the point b, the point d, and the point e are located on the same plane. The points c, d, and e are located on the same plane. The distance between the points a and b and the distance between the points a and c are equal.

In the V-shaped groove of the water conduit 123, a point d that is the bottom on the inner side of the water storage tank 12, that is, the bottom on the water storage section 110 side is below the point a in the height direction of the outer wall 12e and the partition wall 12f. To position. That is, when the humidifying device 1 and the humidifying element 2 are installed horizontally, the point d in the V-shaped groove of the water conduit 123 is the same as the point a when the humidifying device 1 and the humidifying element 2 are installed horizontally. Located vertically below.

In addition, in the V-shaped groove of the water conduit 123, the point e, which is the bottom on the communication channel 120 side, is lower than the point d in the height direction of the outer wall 12e and the partition wall 12f. That is, when the humidifying device 1 and the humidifying element 2 are installed horizontally, the point e is lower than the point d in the V-shaped groove of the water conduit 123.

Therefore, in the first embodiment, the groove-shaped water conduit 123 is formed in the water conduit 111 adjacent to the lowermost end of the inflow port 121 from the water reservoir 110 side to the inside of the water conduit 111. .. The V-shaped groove of the water conduit 123 inclines downward from the point d to the point e. That is, the V-shaped groove of the water conduit 123 is inclined downward from the water reservoir 110 side toward the communication channel 120 side. The angle of inclination of the V-shaped groove of the water conduit 123 from the point d to the point e is preferably 45 degrees or more with respect to the horizontal plane.

By providing the water conduit 123 configured in this way in the water conduit 111, the flow rate of water overflowing from the water storage unit 110 can be kept constant over time and guided to the communication flow path 120. Details of the effect of the water conduit 123 will be described later. Here, for the following description, the distance between the point a and the point b will be referred to as the water conduit width H, and the distance between the point a and the point d will be referred to as the water conduit depth D.

In FIG. 11, the inflow port 121 has two convex corners projecting toward the space where water is stored in the water tank 12, that is, the water storage section 110 side with respect to the horizontal direction. A waterway 123 is provided. That is, the partition wall 12f has two convex corners, and the two corners are points a and h in FIG. By providing the water conduit 123 at the corners in this way, the water that overflows from the water storage unit 110 and surrounds the inlet 121 always passes through the water conduit 123. This utilizes the fact that the water that overflows from the water reservoir 110 and surrounds the inlet 121 tries to get over the corner in an attempt to minimize the surface area due to surface tension. As a result, it is possible to prevent the effect of the water conduit 123 from being lost due to the water overflowing from the water reservoir 110 passing through a route other than the water conduit 123.

If the depth D of the water conduit 123 is sufficiently deep, water will flow through the water conduit 123 to the communication channel 120 regardless of the position where the water conduit 123 is provided, so the water conduit 123 is not necessarily provided at the corner. No need. However, by providing the water conduit 123 at the corner of the inflow port 121, the water conduit depth D can be made shallow, and the upper limit of the water level stored in the water reservoir 110 can be increased.

The water conduit width H is the height of the water surface of the convex meniscus of water that is raised upward by the surface tension from the edge of the partition wall 12f when the water is stored in the water storage section 110 until just before the water overflows from the water storage section 110. It is preferable that the relation of the following expression (1) holds for M.

H>M...(1)

By setting the water conduit width H in this way, the water conduit width H becomes larger than the radius of curvature of the upward convex meniscus of water formed by surface tension, and the central portion of the water conduit 123 is It can function as a groove to allow water to overflow. The height M of the meniscus water surface overflowing from the water storage unit 110 will be described later.

Next, a case where the humidifying device 1 or the humidifying element 2 is installed at an inclination will be described. For example, in a ceiling-embedded humidifier, when the humidifier 1 is installed by using metal fittings for anchor bolts embedded in the ceiling, the humidifier 1 may be installed at a slight inclination from the horizontal. In addition, when the humidifying element 2 is removed by inspection or the like, the humidifying element 2 may be attached with a slight inclination when it is installed again. Therefore, even when the humidifying device 1 or the humidifying element 2 is installed in an inclined manner, the water overflowing from the water storage section 110 of the water storage tank 12 is allowed to pass through the water conduit 123 to keep the flow rate constant over time. Is preferred.

In the water storage tank 12, it is preferable to provide the communication channels 120 at a plurality of locations. Further, it is preferable to provide one or more water conduits 123 for one communication passage 120. By providing one or more water conduits 123 for one communication flow path 120, even if the humidification device 1 or the humidification element 2 is installed at an inclination, it overflows from the water storage section 110 of the water storage tank 12. Water can be prevented from passing through a route other than the water conduit 123. In this way, by providing the water conduit 123 and the communication passage 120 as a pair, or by providing two or more water conduits 123 for one communication passage 120, the water storage tank 12 is inclined. In this case, the water overflowing from the water storage unit 110 can be made to flow into the communication channel 120 through the water conduit 123 of the communication channel 120 located at the lowest position. In addition, by providing a plurality of water conduits 123 for one communication flow path 120, communication is performed from the water storage unit 110 through the water conduit 123 located at the lowest position in the one communication flow path 120. Water can be flowed to the flow path 120.

Next, a series of water flows from the water supply port 11 to the humidifier 20 will be described. A constant flow rate of water controlled by the water supply valve 3a is supplied to the water supply port 11. The water flowing from the water supply port 11 flows into the water tank 12 with a constant flow rate. As shown in FIG. 9, the water 50 that has flowed into the water storage unit 110 drips from a plurality of water injection holes 12 a on the bottom surface of the water storage unit 110, travels along a cylindrical wall surface 12 b having a notch 12 c, and is absorbed by the diffusion member 30. .. The water absorbed by the diffusing member 30 flows down while spreading inside the diffusing member 30, and reaches the lower end of the diffusing member 30.

The lower end of the diffusion member 30 and the upper end of the humidifier 20 are in contact with each other. Therefore, the water flowing down into the diffusing member 30 is transmitted to the humidifying body 20 from the contact portion between the lower end of the diffusing member 30 and the upper end of the humidifying body 20 by the action of the capillary force of the humidifying body 20. The water that has flowed down to the humidifying body 20 permeates the entire humidifying body 20 while spreading inside the humidifying body 20, flows down, and drops from the lower end of the humidifying body 20. At this time, moisture is taken from the surface of the humidifying body 20 by the air ventilated between the humidifying bodies 20, and is discharged from the humidifying element 2 as humidified air. Excess water that has not evaporated in the humidifier 20 flows out of the casing 10 from the drainage section 13 at the bottom. For this reason, the flow rate of the water dropped and drained from the lower end of the humidifying body 20 is the amount of water supplied from the water supply port 11 minus the amount of water taken from the humidifying body 20 as humidified air.

The relationship between the water level of the water stored in the water storage section 110 of the water storage tank 12 and the water injection hole 12a in this series of flows will be described. The water injection hole 12a has a flow resistance when water is passed. There is a relationship of the following formula (2) between the head pressure Pi applied to the inlet of one water injection hole 12a and the flow rate Qi of water passing through this water injection hole 12a. The water head pressure Pi is the head difference from the inlet of the water injection hole 12a to the height of the water level.

Qi=Ci×Ai×√(2×Pi/ρ) (2)

In the above formula (2), Ci is a coefficient depending on the shape of the water injection hole 12a, Ai is the cross-sectional area of the water injection hole, ρ is the density of water, and i is a subscript representing the number when there are a plurality of water injection holes.

Briefly, if the shape of the water injection hole 12a is constant, the higher the water level of the water stored in the water reservoir 110 of the water tank 12, the higher the head pressure Pi applied to the inlet of the water injection hole 12a, and the square root thereof. The flow rate Qi flowing through the water injection hole 12a increases proportionally. When n water injection holes 12a are provided in the water storage unit 110, the total flow rate Qout of water dropped from the water injection holes 12a is expressed by the following equation (3).

Qout=Q1+Q2+Q3+...Qi+...+Qn... (3)

That is, the coefficient C depending on the shape of the water injection hole 12a, the water injection hole cross-sectional area A, and the water injection so that the entire water supply flow rate Qin supplied from the water supply port 11 to the water storage unit 110 of the water tank 12 can be dropped from the water injection hole 12a. By determining the water head pressure Pi applied to the inlet of the hole 12a and the number of the water injection holes 12a, the water supplied to the water storage section 110 of the water tank 12 does not overflow from the water storage section 110, and the diffusion member 30 is supplied from the water injection hole 12a. Can be dripped into. In other words, the water level at which the dropping flow rate of the water injection hole 12a and the supply flow rate to the water storage section 110 are balanced can be made smaller than the maximum water level that the water storage section 110 of the water storage tank 12 can store.

When the humidifying device 1 and the humidifying element 2 are installed horizontally, all the water injection holes 12a are formed so as to be aligned horizontally. This state is also referred to as a state in which the water storage tank 12 is horizontally arranged. When the humidifying device 1 and the humidifying element 2 are installed horizontally, the water level in the water storage section 110 of the water storage tank 12 becomes parallel to the water injection hole 12a. Then, the water head pressure Pi applied to the inlet of the water injection hole 12a in the above formula (2) is equal in all the water injection holes 12a. That is, the flow rate of the water dropped from the water injection hole 12a, that is, the flow rate Qi of the water passing through the water injection hole 12a is uniform in all the water injection holes 12a, and the supply water flowing through the diffusion member 30 and the humidifier 20 is directed in the first direction. It can be evenly flowed.

Next, the stop of the humidifying operation when the humidifying is not necessary at night will be described. For example, the humidifying operation of the humidifying device 1 may be stopped when the room is unattended and no humidification is required, such as at night. Here, leaving the humidifying element 2 in a wet state for a long time is not preferable in terms of hygiene. When bacteria or mold in the air adheres to the humid part of the humidifying element 2 and proliferates, the bacteria or mold spores are transported by the ventilation passing through the surface of the humidifying element 2 when the humidifying operation is resumed, and There is concern that spores may be released into the living room. As a method of suppressing the growth of such bacteria or fungi, it is effective to dry the humidifying element 2 as soon as possible.

From such a viewpoint, when the humidifying device 1 is stopped, it is preferable that the controller 6 controls the water supply valve 3a to be closed and then the blower 5 to operate to dry the humidifying element 2. Here, in order to shorten the drying time of the humidifying element 2, it is necessary to dry the inside of the water storage tank 12 early. However, since the water storage tank 12 has a concave shape, it is difficult to dry by ventilation. Therefore, after the water supply valve 3a is closed, it is important that the water in the water storage tank 12 quickly flows out toward the diffusion member 30.

The bottom surface inside the water storage portion 110 of the water storage tank 12 shown in FIG. 9 is inclined so as to be at the lowest position in the water injection hole 12a portion. Therefore, after the water supply valve 3a is closed, the water in the water storage section 110 of the water storage tank 12 continues to drip due to the head pressure Pi applied to the inlet of the water injection hole 12a. When the water head pressure Pi applied to the inlet of the water injection hole 12a approaches zero as much as possible, the capillary force of the diffusion member 30 brought into contact with the water injection hole 12a allows the water in the water storage section 110 to be smoothly absorbed by the diffusion member 30. To be done. Therefore, the water in the water storage section 110 of the water storage tank 12 flows out to the outside through the diffusion member 30, and the water in the water storage tank 12 can be dried quickly.

As described above, by using the container having the open upper part in the water storage tank 12 and arranging the water injection hole 12a at the lowest position on the inner bottom surface of the water storage part 110, the water storage when the humidifying element 2 is not used for a long time. It is possible to ensure the hygiene inside the tank 12. Further, compared to a water supply system in which the water storage tank 12 is formed of a closed container and water is dripped, parts such as a seal member for sealing the water storage tank 12 are unnecessary, the structure can be simplified, and the cost is low and long-term reliability is achieved. It is possible to provide the humidifying element 2 having high efficiency.

Next, the secular change of the water storage tank 12 will be described. When the hardness component contained in the feed water in the feed water and evaporation residues such as silica, iron rust, and dust are accumulated in the water injection hole 12a over time, the water injection hole cross-sectional area Ai in the above formula (2) becomes small. If the water supply flow rate to the water storage tank 12 is constant, the head pressure Pi applied to the inlet of the water injection hole 12a becomes large. That is, the water level in the water storage section 110 of the water storage tank 12 rises. In this case, since all the water stored up to the upper end of the partition wall 12f can be dripped from the water injection hole 12a, the water storage section 110 is preferably a container as deep as possible. That is, it is preferable that the water storage tank 12 is a container as deep as possible. However, due to the constraints of the dimensions of the water storage tank 12 and the casing 10, there is an upper limit value for the allowable amount of water level rise, that is, the depth of the water storage section 110 and the water storage tank 12.

When the evaporation residue or dust enters the water injection hole 12a, the water level in the water storage section 110 of the water storage tank 12 rises as described above. Since the inflow port 121 is located at a position lower than the partition wall 12f of the water storage tank 12, when the water level in the water storage unit 110 rises and the water is about to overflow from the water storage unit 110, the water in the water storage unit 110 will flow into the inflow port. It flows into 121. The water flowing into the inflow port 121 flows through the communication flow path 120, flows down from the outflow port 122 to the diffusion member 30, and is supplied to the humidifying body 20. That is, the communication flow path 120 functions as an auxiliary flow path when the water injection hole 12a becomes difficult to pass water.

The water flowing through the communication channel 120 when the water overflows from the water storage unit 110 will be described in detail. FIG. 12 is a schematic diagram showing how the water overflowing from water reservoir 110 flows into communication channel 120 shown in FIG. 11 in the first embodiment. The V-shaped water conduit 123 is provided at the inflow port 121, so that the flow passage cross section is narrowed, and the water flows from the inclined water conduit 123 to the communication passage 120 so that the water is communicated. It flows along the flow path 120 and flows continuously without interruption.

Next, the water that flows into the communication channel 120 when the above-mentioned water conduit 123 is not provided will be described. As described above, the shapes shown by the broken lines in FIG. 11 represent the shapes of the partition wall 12f and the inflow port 121 when the water conduit 123 is not provided. Further, FIG. 7 also shows the behavior of the water overflowing from the water storage unit 110 into the communication flow path 120 when the water conduit 123 is not provided. In FIG. 7, when the humidifying device 1 and the humidifying element 2 are installed horizontally, the water level line 131 extends to the same surface as the inflow port 121 in the water storage section 110 of the water tank 12, that is, the same surface as the upper surface 12g of the partition wall 12f. It is a water level line in a state where water 50 is accumulated up to. When the humidifying device 1 and the humidifying element 2 are installed horizontally, the water level line 132 rises upward due to surface tension immediately before the water 50 in the water storage section 110 of the water storage tank 12 overflows and flows out into the communication channel 120. The shape of the convex meniscus of the water 50 is shown.

The difference between the water level line 131 and the water level line 132 in the height direction of the partition wall 12f and the outer wall 12e, that is, in the vertical direction when the humidifying device 1 and the humidifying element 2 are installed horizontally is the difference of the above-mentioned convex meniscus. The height M of the water surface. The height M of the water surface of the convex meniscus is low if the inner surface of the water storage section 110 is hydrophilic, and is high if the inner surface of the water storage section 110 is hydrophobic. Since the resin material is used for the water storage tank 12 and the surface is hydrophobic, the height M of the water surface of the convex meniscus is relatively high.

Here, in the case where the humidifying device 1 and the humidifying element 2 are installed horizontally, when the water conduit 123 is not provided and a constant flow rate of water is supplied to the water reservoir 110 with all the water injection holes 12a closed. think of. The water supplied to the water storage unit 110 does not immediately flow to the communication channel 120 after being stored up to the height position of the water level line 131. The water supplied to the water storage unit 110 is stored until the water level reaches the height position of the water level line 132, then flows at once in the communication flow path 120, the water level decreases to the height of the water level line 131, and then the water level line. The behavior of gradually accumulating up to the position of 132 is repeated. That is, a period in which water is stored in the water storage unit 110 to a limit height due to the surface tension higher than the upper surface of the partition wall 12f, and then a period in which water overflowing from the water storage unit 110 flows into the communication flow path 120 all at once are repeated.

Further, when the water accumulated up to the height of the water level line 131 flows into the communication flow path 120 at once, the rushed water drops immediately after passing the inflow port 121 and flows. Therefore, in the case where the water conduit 123 is not provided, the water flowing in the communication flow path 120 has a constant flow direction but changes its amount periodically or with irregular fluctuation, that is, intermittent flow. It is a pulsating flow, and the flow rate flowing through the humidifying body 20 fluctuates with time.

Further, since the inner surface of the water storage section 110 is hydrophobic, the amount of water stored in the water storage section 110 between the water level lines 131 and 132 at the height position is such that the inner surface of the water storage section 110 is hydrophilic. Compared with the case, a large amount of water flows into the humidifier 20 at one time. It should be noted that this phenomenon is not limited to the case where the inner surface of the water storage section 110 of the water storage tank 12 is hydrophobic, but as long as the inner surface of the water storage section 110 is not superhydrophilic, even if it is hydrophilic, a large amount of water is present at one time. There is no change in that water flows into the humidifier 20.

When a large amount of water flows into the humidifying body 20 intermittently at once, the following problems may occur.

In other words, a momentum of a large flow of water is instantaneously supplied to the humidifying body 20, so that the flow rate of water that is drained before being absorbed by the humidifying body 20 while being supplied to the humidifying body 20 increases. Therefore, the humidification of the humidifying body 20 becomes insufficient, and the humidifying performance decreases. Then, since the water supply to the humidifying body 20 is biased in time series, the amount of water absorbed by the humidifying body 20 is reduced, and the humidifying performance is deteriorated as compared with the case where the humidifying body 20 is continuously supplied with water.

In addition, the water droplets that cannot be absorbed by the humidifier 20 fly on the air blown to the humidifier element 2 and scatter, causing water leakage outside the humidifier 1.

On the other hand, the humidifying device 1 according to the first embodiment is provided with the above-described groove-shaped water conduit 123 at the inlet of the communication channel 120, so that the width of the channel through which water flows from the water reservoir 110 to the communication channel 120. Can be restricted, and a large amount of water can be prevented from flowing into the communication channel 120 at one time.

Further, since the groove-shaped water conduit 123 is inclined downward from the water storage part 110 side toward the communication channel 120 side, the water flowing over the water conduit 123 is immediately dropped by the action of gravity, so that an intermittent flow occurs. Can be prevented from occurring.

In addition, in the humidifying device 1 according to the first embodiment, when the humidifying device 1 and the humidifying element 2 are installed horizontally, that is, in the vertical plane direction perpendicular to the height direction of the outer wall 12e and the partition wall 12f. The communication passage 120 is partitioned from the water storage section 110 by the partition wall 12f that extends from the outer wall 12e toward the water storage section 110. The water conduit 123 is provided on the upper surface of the partition wall 12f at the corner in the vertical plane direction. As a result, the water that is about to flow into the communication channel 120 from the water storage unit 110 side can surely pass through the water conduit 123.

That is, the humidifying device 1 according to the first embodiment is provided with the above-described groove-shaped water conduit 123 at the inlet of the communication passage 120, so that the water injection hole 12a is temporarily cut off by the evaporation residue or impurities in the water. Even when the area becomes small or the area is closed, the water overflowing from the water storage section 110 of the water storage tank 12 can be continuously flowed to the communication flow path 120. Therefore, it is possible to reduce the possibility of splashing of water and deterioration of the humidification performance due to intermittent supply of the water overflowing from the water storage unit 110 to the humidifier 20.

Further, the humidifying device 1 according to the first embodiment can prevent the humidifying body 20 from deteriorating by utilizing the flushing effect of the water supplied to the humidifying element 2. The humidifying device 1 according to the first embodiment is a drip-type humidifying device, and supplies a larger amount of water than the amount to be humidified to the humidifying body 20 to wash away the surface of the humidifying body 20 for a long time. It has an advantage that it can be used, and deterioration of the humidifying element 20 can be prevented by utilizing a washing effect of water supplied to the humidifying element 2.

FIG. 13 shows a comparison between the humidifier of Sample A having the structure of the humidifier 1 according to the first embodiment and the humidifier of Sample B having the same configuration as Sample A except that the water conduit 123 is not provided. FIG. 5 is a diagram showing an example of an experimental result showing a relationship between a flow rate (g/min) in the communication channel 120 and an elapsed time (sec). FIG. 13 shows the results of comparing the flow rates of water flowing through the communication channels 120 in Sample A and Sample B when a constant flow rate of water of 5 g/min was supplied to the water storage unit 110.

From FIG. 13, it can be seen that in Sample B, the flow rate of water flowing through the communication channel 120 is pulsating, whereas in Sample A, the flow rate of water flowing through the communication channel 120 is almost constant. As a result, it can be seen that in the humidifying device 1 according to the first embodiment, the water overflowing from the water storage section 110 of the water storage tank 12 can be continuously flown into the communication flow path 120.

As described above, the humidifying device 1 according to the first embodiment prevents deterioration of the humidifying body 20 by utilizing the flushing effect of the water supplied to the humidifying element 2, and the flow rate of the water flowing in the humidifying body 20. It is possible to realize an inexpensive humidifying device that has stable humidifying performance for a long period of time while keeping the temperature constant over time and preventing the water generated from the humidifying body 20 from splashing.

Embodiment 2.
FIG. 14 is a perspective view around the inflow port 121 of the humidifying element according to the second embodiment of the present invention. The humidifying element according to the second embodiment has the same configuration as the humidifying element 2 according to the first embodiment except that the shape of the communication channel 120 is different. Therefore, the description of the portion having the same configuration will be omitted.

In the humidifying element according to the second embodiment, the water conduit 111 has a cylindrical shape, and the water conduit is provided at at least one location on the upper surface of the water conduit 111. That is, in the humidifying element according to the second embodiment, the inflow port 121 is circular and the communication flow channel 120 is a columnar flow channel. As a result, the water that is about to overflow from the water storage unit 110 into the communication flow path 120 via the inflow port 121 rises uniformly on the upper surface of the cylinder. Therefore, by providing only one water conduit 123 at the inflow port 121, water can be reliably passed through the water conduit 123 and flow from the water reservoir 110 to the communication flow path 120. Further, the water conduit 123 may be provided at a plurality of positions on the upper surface of the partition wall 2f, that is, the upper surface of the water conduit 111.

The humidifying element according to the third embodiment has the same configuration as that of the humidifying element 2 according to the first embodiment except that the shape of the water conduit 123 is different, and therefore the description of the portion having the same configuration is omitted.

In the humidifying element according to the third embodiment, the water conduit 123 is a U-shaped groove. The bottom of the groove is formed by rounding the bottom of the V-shaped groove forming the water conduit 123 in the first embodiment. In this case as well, the same effect as when the water conduit 123 is formed by a V-shaped groove is obtained.

The humidifying element according to the second embodiment configured as described above has the same effect as the humidifying element 2 according to the above-described first embodiment.

In addition, the water conduit 123 provided at the inflow port 121 can narrow the cross section of the flow path, and the water flows along the communication flow path 120 because the water flow path 123 is inclined from the water storage section 110 side to the communication flow path 120 side. Any shape may be used as long as it has a continuous flow without interruption. Therefore, the shape of the bottom of the water conduit 123 is not particularly limited. That is, the shape of the groove forming the water conduit 123 is not limited to the V-shaped groove or the U-shaped groove.

Fourth Embodiment
FIG. 16 is an enlarged perspective view of the vicinity of the inlet 121 of the humidifying element according to the fourth embodiment of the present invention. The humidifying element according to the fourth embodiment has the same configuration as the humidifying element 2 according to the first embodiment except that the position of the inflow port 121 is different, and therefore the description of the portion having the same configuration is omitted.

The inflow port 121 shown in FIG. 16 is provided as an opening on the side surface of the partition wall 12f. In FIG. 16, the region on the inner side of the inflow port 121 that is visible inside the circular inflow port 121 is the water reservoir 110, and the region on the inner side of the inflow port 121 that is visible outside the circular inflow port 121 is in communication. The flow path 120. A water conduit 123 is provided at the bottom of the inflow port 121. That is, a groove-shaped water conduit 123 is formed in the water conduit 111 adjacent to the lowermost end of the inflow port 121, extending from the water storage portion 110 side to the inside of the water conduit 111.

With such a configuration, even if the shape of the upper part of the water storage tank 12 is restricted by, for example, providing a lid on the upper part of the water storage tank 12, the flow rate of the water overflowing from the water storage part 110 is kept constant over time. , Can be led to the communication channel 120.

Embodiment 5.
FIG. 17 is an enlarged perspective view of the vicinity of the inflow port 121 of the humidifying element according to the fifth embodiment of the present invention. The humidifying element according to the fifth exemplary embodiment has the same configuration as the humidifying element 2 according to the first exemplary embodiment except that an additional guide member 141 is added to the inflow port 121, and thus has the same configuration. The description of is omitted.

In the humidifying element of the fifth embodiment, the partition wall 12f is thinned as shown in FIG. 17 in order to reduce the material. In this case, since the partition wall 12f is thin due to the thinning of the partition wall 12f, the length of the water conduit 123 becomes short. The length of the water conduit 123 is the length of the water conduit 123 in the thickness direction of the partition wall 12f, and is the length in the extending direction of the V-shaped groove.

For this reason, in the humidifying element in the fifth embodiment, a guide member 141 is additionally provided in order to supplement the function of the water conduit 123. The guide member 141 is provided to extend from the end of the water conduit 123 on the communication channel 120 side toward the communication channel 120 side, that is, from the water conduit 123 toward the inside of the water conduit 111. The downward inclination of the upper surface of the guide member 141 is larger than the inclination of the water conduit 123. The downward inclination of the upper surface of the guide member 141 may be the same as the inclination of the water conduit 123 as long as the water flowing from the water reservoir 110 to the water conduit 123 can be guided to the communication passage 120. It may be smaller than the inclination of 123.

The humidifying element according to the fifth embodiment configured as described above has the same effect as the humidifying element 2 according to the above-described first embodiment.

In the humidifying element according to the fifth embodiment, by configuring the water storage tank 12 as described above, cost reduction due to thinning of the material of the water storage tank 12 and the risk of deterioration of the humidification performance of the humidifying element 2 and water content described above.
