Description

  The present invention relates to a transpiration body that evaporates water contained in a porous material and cools air or the like by heat of evaporation of water.

  Conventionally, a cold air introduction method using evaporative cooling has been adopted in private houses and the like. For example, a sunny garden and a cool garden covered with trees are placed in front of and behind the room, the rising air in the sunny garden attracts cool air from the cool garden, and at the entrance to the cool garden side. There is known a method of placing unglazed firewood containing water to cool the water in the firewood by evaporating water from the surface and humidifying and cooling the air flowing into the room.

  As a further improvement of this type of cooling method, a transpiration apparatus is known in which walls and louvers made of a porous material are cooled by the evaporation heat of water. For example, the structure described in Patent Document 1 below includes a porous member that is long in the vertical direction as a transpiration main body for transpiration of water. In Patent Document 1, a structure in which water is supplied from a header in the vicinity of the center of the upper surface of the porous member, a water supply pipe is inserted into the center of the porous member, a small hole is provided in the water supply pipe, and the small hole is provided. The structure which permeate | transmits the water supplied to the water supply pipe | tube through the porous member is disclosed.

JP 2003-139451 A

  However, in the configuration described in Patent Document 1, when the thickness of the porous member is excessive with respect to the header that supplies water to the porous member from above the porous member, the water supplied from the header Tends to be biased in the portion directly under the header, and is difficult to reach the entire porous member. For example, when the header is disposed above the central portion of the porous member, water is supplied biased toward the central portion of the porous member. Further, even when water is supplied from the water supply pipe through the small hole, the water is biased and supplied to a portion close to the water supply pipe. Thus, it was difficult to supply water to the whole porous member which is a transpiration main-body part.

  An object of this invention is to provide the transpiration | evaporation body which can supply water to the whole transpiration | evaporation main-body part.

The transpiration body which solved the above-mentioned problem extends vertically below the water supply header of the water supply header which can supply water directly below or around the water supply port, and temporarily contains the water supplied from the water supply header. A transpiration main body portion that transpirations and transpiration, a water diffusion portion that is disposed between the upper surface portion of the transpiration main body portion and the water supply port and uniformly diffuses water supplied from the water supply port to the upper surface portion, and a water diffusion portion And a water diffusion part including a water diffusion member that receives water supplied from a water supply port facing the upper surface of the transpiration main body part, and the water diffusion member and the outer cylinder. A gap is formed between the cylinder and a vent hole is formed in the outer cylinder .

  According to this transpiration body, since the water diffusion part is arranged between the upper surface part of the transpiration body part and the water supply port, the water supplied from the water supply port does not fall directly on the transpiration body part, but the water diffusion part. Will fall down. The water diffusion unit uniformly diffuses the water supplied from the water supply port to the upper surface of the transpiration main body. Therefore, the upper surface portion of the transpiration main body can receive water not only directly under the water supply port and its peripheral portion, but also at the edge, so that water is supplied only to a part of the transpiration main body. Is prevented. Therefore, water can be supplied to the entire transpiration body.

Moreover, in the above transpiration body, the water diffusion portion includes a filter member as a water diffusion member, and the filter member has a fiber layer that permeates the water by capillary action while receiving water supplied from the water supply port. In this case, since the fiber layer of the filter member permeates the water by capillary action while receiving water, the water penetrates the entire fiber layer. Therefore, water falls to the edge of the upper surface part of the transpiration body part, and water can be reliably and easily supplied to the entire transpiration body part.

  Moreover, in the said transpiration | evaporation body, the center part of the filter member protrudes in the mountain shape toward the upper direction, and the outer peripheral part of the filter member is lower than the center part. In this case, the water that has permeated the fiber layer of the filter member is more likely to fall from the outer peripheral portion than the central portion. Thereby, more water can be supplied to the peripheral part of the transpiration body part. Since the peripheral part of the transpiration main body part faces the outside and the transpiration is actively performed, efficient transpiration can be performed.

Moreover, in the above transpiration body, the water diffusion part includes an enclosure part that is provided in the outer cylinder and surrounds the filter member, and a gap is formed between the enclosure part and the filter member. In this case, water leaks from the gap between the peripheral portion of the filter member and the surrounding portion, and water can be actively leaked not only from directly below the filter member but also from the peripheral portion thereof. As a result, more water can be supplied to the peripheral portion of the transpiration main body, and efficient transpiration can be performed.

Further, in the transpiration body, the water diffusion portion includes a dish body as a water diffusion member having a horizontal width smaller than that of the upper surface portion of the transpiration body portion, and the dish body includes a bottom plate portion and a peripheral portion of the bottom plate portion. And a peripheral wall portion that rises from. In this case, the water supplied from the water supply port is once stored in the dish body, and when the dish body is full, the water overflows from the peripheral wall portion of the dish body and falls to the upper surface portion of the transpiration main body portion. . By utilizing such an overflow effect, water can be dropped not only directly below the water supply port but also to the edge of the upper surface portion, and water can be reliably and easily supplied to the entire transpiration body portion. .

  Further, in the above transpiration body, the dish body has one or a plurality of openings in the bottom plate part, and has an opening peripheral wall part having the same height as the peripheral wall part around each opening part. In this case, since the peripheral wall part which overflows water is provided not only at the peripheral part of the bottom plate part but also around the opening part, the water can be dropped from the opening part by overflow. Therefore, more peripheral wall portions can be provided, and water can be diffused more uniformly with respect to the upper surface portion.

  Moreover, in the said transpiration | evaporation body, while the bottom plate part of a plate body has a groove part, it has a some hole part in each of parts other than a groove part and a groove part. In this case, water falls from the hole portion of the groove portion, and the water that has accumulated in the groove portion and overflows to the portion other than the groove portion also falls from the hole portions other than the groove portion. Therefore, water can be dropped from the whole bottom plate part, and water can be diffused more uniformly with respect to the upper surface part.

  Moreover, in the above transpiration body, a pot body having a plantable soil layer and having a plurality of holes at the bottom is provided above the water diffusion portion and above or below the water supply port. In this case, water can be allowed to pass through the soil layer in the pot body and the hole in the bottom, whereby the water falling from the bottom of the pot body has already diffused. And since the water diffused by the pot will fall into the water diffusion part, the diffusion of water in the water diffusion part becomes even more uniform.

  According to the present invention, water can be supplied to the entire transpiration body.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant descriptions are omitted.

  As shown in FIG. 1, a transpiration louver 1 is a transpiration device that is installed near a window or entrance of a building, in a garden, etc., and cools ambient air or air flowing into the building. This transpiration louver 1 constitutes a part of the exterior. The transpiration louver 1 is erected on a concrete base 2, and includes a plurality of transpiration bodies 3 for temporarily containing water therein and transpiration of the water, and a water supply header for supplying water to the plurality of transpiration bodies 3. 4 is provided. In addition, in FIG. 1, the example in which the five transpiration bodies 3 were arranged in parallel is shown. For ease of explanation, the four on the left side in the figure show the appearance from the front, and the one on the right end in the figure shows a longitudinal section.

  Each transpiration body 3 has a cylindrical outer shape extending in the vertical direction, and extends upward from the ground G. The lower end of the transpiration body 3 is embedded in the foundation 2. The transpiration body 3 has a cylindrical outer cylinder 6 made of stainless steel, and a transpiration body portion 7 accommodated in the outer cylinder 6. The outer cylinder 6 is formed with a plurality of horizontally long vent holes 6a throughout. With such a configuration, the outer cylinder 6 accommodates and holds the transpiration main body portion 7 and ensures air permeability to the transpiration main body portion 7. The material of the outer cylinder 6 is not limited to stainless steel, and may be made of aluminum, for example. The outer cylinder 6 is preferably made of a material having high corrosion resistance. The shape of the vent 6a can be changed as appropriate.

  The water supply header 4 has a header pipe 4a extending horizontally above the plurality of vaporizers 3, and a water supply port 4b branched from the header pipe 4a to allow water to flow (or dripping) into the vaporizer 3. ing. A water supply means (for example, a pump) (not shown) is connected to the base end of the header pipe 4a. A water supply nozzle may be provided at the tip of the water supply port 4b, or a water supply nozzle may not be provided and only a pipe may be provided. The diameter of the water supply port 4 b is smaller than the inner diameter of the outer cylinder 6. The water supply port 4b is configured to be able to supply water only directly below or around the water supply port 4b.

  The transpiration body 3 has a bowl 8 suspended from the upper end of the outer cylinder 6. The bowl 8 includes an inverted frustoconical side portion 8a, a bottom portion 8b provided continuously with the lower end of the side portion 8a, and a flange portion 8c provided continuously with the upper end of the side portion 8a and suspended on the outer cylinder 6. And have. The pot body 8 is filled with a soil layer 9, and plants 10 are planted in the soil layer 9. The pot body 8 is disposed below the water supply port 4 b, and the water flowing down from the water supply port 4 b penetrates into the soil layer 9. The pot body 8 has a function of improving the design of the transpiration louver 1 by the plant 10 and diffusing water supplied to the transpiration main body 7. In addition, the water supply port 4b may be arrange | positioned in what position, as long as water falls in the pot body 8 from the water supply port 4b. That is, the water supply port 4 b may be disposed above the central portion of the pot body 8 or may be disposed above the edge of the pot body 8.

  A reinforcing plate is attached to an upper end portion of the outer cylinder 6 in which the pot body 8 is accommodated so as to surround the pot body 8. The outer cylinder 6 is required to have air permeability in a portion where the transpiration main body portion 7 is provided, and does not have to have a ventilation function around the pot body 8.

  The transpiration main body 7 is for temporarily containing water supplied from the water supply port 4b of the water supply header 4 and causing it to evaporate. The transpiration body portion 7 is made of porous particles, and these particles are filled in the outer cylinder 6 to a predetermined height, thereby extending in the vertical direction below the water supply port 4b. The upper surface portion 7a of the transpiration main body portion 7 has a diameter corresponding to the inner diameter of the outer cylinder 6, and thus the diameter of the upper surface portion 7a is larger than the diameter of the water supply port 4b.

  A material having a large surface area per unit volume is suitable for the transpiration main body 7. For example, lightweight cellular concrete (ALC: Autoclaved Lightweight Concrete) pulverized in a granular form can be used. In this case, granular ACL molded for the transpiration main body 7 may be used, or ALC discarded as building waste may be pulverized, granulated, and recycled. The particle size of each granule of the transpiration body part 7 is, for example, about 10 to 50 mm. Note that fine particles of 10 mm or less may be used, or coarse particles of 50 mm or more may be used.

  Fig.2 (a) is sectional drawing which shows the upper part of the evaporation body 3 in FIG. In the transpiration body 3 of the present embodiment, the water that is disposed between the upper surface portion of the transpiration body portion 7 and the water supply port 4b and uniformly diffuses the water supplied from the water supply port 4b to the upper surface portion 7a. A diffusion unit 15 is provided. The water diffusion portion 15 is placed on the upper surface portion 7a and faces the upper surface portion 7a, and the cylindrical surrounding portion 6b that is attached to the inner surface of the upper end portion of the outer cylinder 6 and surrounds the filter member 11 Have The filter member 11 is disposed between the bottom portion 8 b of the pot body 8 and the upper surface portion 7 a of the transpiration main body portion 7. The surrounding portion 6 b is a metal plate material and surrounds the pot body 8 and the filter member 11. Further, an annular gap 14 is formed between the filter member 11 and the surrounding portion 6b.

  As shown in FIGS. 2B and 2C, the filter member 11 has a disk shape, and is formed by overlapping two filters, that is, the upper filter member 12 and the lower filter member 13. . The upper surface portion 12d of the upper filter member 12 faces the bottom portion 8b of the bowl body 8 with a predetermined distance from the bottom portion 8b, and the lower surface portion 13d of the lower filter member 13 faces the upper surface portion 7a of the transpiration main body portion 7. It is in contact. The upper and lower filter members 12 and 13 are three-dimensional solid knitted fabrics made of, for example, PET (polyethylene terephthalate).

  More specifically, the upper filter member 12 receives water flowing down from the water supply port 4b, and an upper osmotic layer (fiber layer) 12a that permeates the entire water by capillary action. Provided on the lower surface of the upper osmosis layer 12a, provided on the lower surface of the support layer 12b, a support layer 12b made of a woven fabric that supports the upper osmosis layer 12a without hindering the flow of water from the upper osmosis layer 12a, A lower osmotic layer 12c having the same configuration as the upper osmotic layer 12a. Similarly to the upper filter member 12, the lower filter member 13 includes an upper osmotic layer 13a, a support layer 13b, and a lower osmotic layer 13c. As the upper filter member 12 and the lower filter member 13, for example, "Fusion (registered trademark)" manufactured by Asahi Kasei Fibers Corporation can be used. In this configuration, the filter member 11 has a double-layer configuration, but may be a single-layer configuration or a triple-layer configuration or more.

  The surrounding portion 6b also serves as a reinforcing plate that reinforces the upper end portion of the outer cylinder 6. As the surrounding portion, it may also serve as a reinforcing plate as in the present embodiment, or an annular plate material that surrounds only the filter member 11 may be used. Furthermore, without providing a separate plate material, the portion of the outer cylinder 6 may be the surrounding portion without forming the vent hole 6 a around the filter member 11.

  Furthermore, the pot body 8 disposed above the water diffusing portion 15 has a plurality of holes 8d in the bottom portion 8b. The plurality of holes 8d are for dropping (or flowing down) the water supplied from the water supply port 4b and passing through the soil layer 9 onto the upper surface portion 12d of the filter member 11. The holes 8d may be arranged at any position as long as water can be dripped onto the filter member 11 from the holes 8d. However, the holes 8d are arranged evenly so that the water can be evenly dripped onto the filter member 11. It is preferred that

  In the transpiration body 3 of the transpiration louver 1 having the above configuration, the pot body 8 is disposed below the water supply port 4b, and the filter member 11 of the water diffusion portion 15 is disposed below the pot body 8, so that the water supply port The water flowing down from 4b diffuses planarly while passing through the soil layer 9 in the pot body 8 and the hole 8d in the bottom 8b. Next, the water diffused by the pot body 8 falls on the filter member 11 of the water diffusing portion 15, and the water permeates the filter member 11 by capillary action. And water falls on the substantially whole surface of the upper surface part 7a of the transpiration body part 7, and water spreads over the whole transpiration body part 7 reliably.

  According to the transpiration body 3, the water diffusion portion 15 is disposed between the upper surface portion 7 a of the transpiration body portion 7 and the water supply port 4 b, so that the water supplied from the water supply port 4 b falls directly to the transpiration body portion 7. Without falling, it falls on the filter member 11 of the water diffusion part 15. The water diffusion portion 15 uniformly diffuses the water supplied from the water supply port 4b to the upper surface portion 7a of the transpiration main body portion 7. Therefore, the upper surface portion 7a includes not only the portion directly below and around the water supply port 4b. Water can also be received at the edge, and this prevents water from being supplied to only a part of the transpiration body 7. Therefore, water is supplied to the entire transpiration main body 7, and a good transpiration state can be obtained.

  Moreover, since the upper osmosis | permeation layer 12a of the filter member 11 permeate | transmits the water by a capillary phenomenon, receiving water, water will osmose | permeate the whole upper osmosis | permeation layer 12a. Therefore, water falls to the edge of the upper surface portion 7 a of the transpiration main body 7, and the water is reliably and easily supplied to the entire transpiration main body 7.

  In particular, in this embodiment, the filter member 11 is composed of a plurality of layers of an upper filter member 12 and a lower filter member 13, and each filter member 12, 13 has two permeation layers (permeation layers 12 a, 12 c and permeation layers). 13a, 13c), the water penetration / diffusion effect in the filter member 11 is enhanced. The layer configuration of the filter member 11 and the fiber density of the filter members 12 and 13 are determined in relation to the momentum of water supplied from the water supply port 4b, the supply time, the transpiration rate, and the like. In the case where the filter member 11 is used as a header of a certain type in which water is temporarily stored on the water and then supplied to the transpiration main body portion 7 depending on the osmotic force of the filter member 11, the fiber density of the filter member 11 is used. In addition, it is desirable to have a multilayer structure. On the other hand, when only the water diffusing power of the filter member 11 is expected, water is not retained in the filter member 11 for a long period of time, and the water supply is adjusted on the water supply header 4 side, a certain degree of permeability. A single-layer filter member having the following is employed.

  Further, since a gap 14 is formed between the filter member 11 and the surrounding portion 6b, water leaks from the gap 14, and not only directly below the filter member 11, but also from the peripheral portion thereof. Water can be leaked out. As a result, more water is supplied to the peripheral portion of the transpiration main body 7. Since the peripheral part of the transpiration body part 7 faces the outside and is a part where transpiration is actively performed, efficient transpiration is performed.

  Moreover, the water falling from the bottom 8b of the pot 8 has already diffused by allowing water to pass through the soil layer 9 in the pot 8 and the hole 8d of the bottom 8b. Since the water diffused by the pot 8 falls to the water diffusion part 15, the water diffusion in the water diffusion part 15 becomes even more uniform. When the pot body 8 is provided below the water supply port 4b as in the present embodiment, water from the water supply port 4b can be used for a plurality of purposes. Furthermore, the design property is also improved by the plant 10 planted in the pot body 8.

  FIG. 3 is a cross-sectional view showing the upper part of the transpiration body 3A according to the second embodiment. The difference between the transpiration body 3A shown in FIG. 3 and the transpiration body 3 shown in FIG. 2A is that a water diffusion portion 15A having a mountain-shaped filter member 11A is provided instead of the filter member 11. The material and layer structure of the filter member 11A are the same as those of the filter member 11. The central portion 11a of the filter member 11A protrudes upward in a mountain shape, and the outer peripheral portion 11b of the filter member 11A is lower than the central portion 11a. Furthermore, the peripheral edge portion 11c of the filter member 11A is in close contact with the surrounding portion 6b.

  According to the transpiration body 3A having the above-described configuration, water that has permeated the fiber layer of the filter member 11A is more likely to be unevenly distributed in the outer peripheral portion 11b than in the central portion 11a, and depending on the fiber density of the filter member 11, Water tends to accumulate above the outer peripheral portion 11b, and as a result, water tends to fall from the peripheral portion 11c toward the upper surface portion 7a of the transpiration main body portion 7. As a result, more water is supplied to the peripheral portion of the transpiration main body 7 and efficient transpiration is performed.

  Further, since the peripheral edge portion 11c of the filter member 11A is in close contact with the surrounding portion 6b, water is prevented from leaking from the peripheral edge portion 11c.

  Fig.4 (a) is sectional drawing which shows the upper part of the transpiration body 3B which concerns on 3rd Embodiment. The difference between the transpiration body 3B shown in FIG. 4A and the transpiration body 3 shown in FIG. 2A is that, instead of the filter member 11, a water diffusion portion 15B having a circular dish body 16 is provided. is there. This dish body 16 has a horizontal width, that is, a diameter smaller than that of the upper surface part 7a of the transpiration body part 7, and an annular gap 17 is formed between the dish body 16 and the surrounding part 6b. . 4 (a) and 4 (b), the dish body 16 is formed at the center of the doughnut-shaped bottom plate portion 16a, the peripheral wall portion 16b rising from the peripheral portion of the bottom plate portion 16a, and the bottom plate portion 16a. It has a circular opening 16c and an opening peripheral wall 16d that rises from the periphery of the opening 16c. The height of the opening peripheral wall portion 16d is the same as the height of the peripheral wall portion 16b. In addition, it is preferable that the hole 8d of the bottom part 8b of the pot body 8 is provided at least directly above the bottom plate part 16a.

  According to the transpiration body 3B having the above configuration, the water supplied from the water supply port 4b is once stored in the dish body 16, and when the dish body 16 becomes full, the water overflows from the peripheral wall portion 16b of the dish body 16. Falls to the upper surface portion 7a of the transpiration main body portion 7. By utilizing such an overflow effect, water can be dropped not only directly below the water supply port 4b but also to the edge of the upper surface portion 7a, and water can be reliably and easily supplied to the entire transpiration body portion 7. The

  Moreover, since the surrounding wall part which overflows water is provided not only in the peripheral part of the baseplate part 16a but the circumference | surroundings of the opening part 16c, water can be dropped by overflow from the opening part 16c. Therefore, more peripheral wall parts 16b and 16d can be provided, and water diffuses more uniformly with respect to the upper surface part 7a.

  Fig.5 (a) is sectional drawing which shows the upper part of the transpiration body 3C which concerns on 4th Embodiment, FIG.5 (b) is a top view of the plate body of the transpiration body 3C. The difference between the transpiration body 3C shown in FIG. 5A and the transpiration body 3B shown in FIG. 4A is that the water diffusion has a dish body 18 made of a multi-circular bowl-shaped member instead of the dish body 16. This is a point provided with a part 15C. The dish 18 is formed by concentrically arranging triple bowl-shaped members capable of storing water. The plate body 18 includes a doughnut-shaped bottom plate portion 18 a arranged in a triple manner, a peripheral wall portion 18 b rising from an outer edge portion of the outermost peripheral bottom plate portion 18 a, a space between the facing bottom plate portions 18 a and 18 a, and a central portion of the plate body 18. And an opening peripheral wall portion 18d rising from the periphery of the opening portion 18c. The height of the opening peripheral wall portion 18d is the same as the height of the peripheral wall portion 18b. In addition, it is preferable that the hole 8d of the bottom part 8b of the pot body 8 is provided at least directly above the bottom plate part 18a. The triple hook-shaped member is fixed on the cross-shaped connecting / supporting member 19. In this embodiment, the hook-shaped member is triple, but it can be double or quadruple or more.

  According to the transpiration body 3C having the above-described configuration, it is possible to achieve the same operations and effects as the above-described transpiration body 3B, and it is possible to provide longer peripheral wall portions 18b and 18d.

  Fig.6 (a) is sectional drawing which shows the upper part of the transpiration body 3D which concerns on 5th Embodiment, FIG.6 (b) is a top view of the plate body of the transpiration body 3D. The difference between the transpiration body 3D shown in FIG. 6A and the transpiration body 3C shown in FIG. 5A is that, instead of the dish body 18, a water diffusion section having a dish body 20 made of a spiral bowl-shaped member. It is a point with 15D. In the dish body 20, one bowl-shaped member capable of storing water is arranged in a spiral shape like a mosquito coil. The plate 20 has a bottom plate portion 20a that extends in a spiral shape, a peripheral wall portion 20b that rises from an edge in the width direction of the bottom plate portion 20a, and an opening portion 20c that is formed between the peripheral wall portions 20b and 20b facing each other. ing. The height of the peripheral wall portion 20b is uniform. In addition, it is preferable that the hole 8d of the bottom part 8b of the pot body 8 is provided at least directly above the bottom plate part 20a.

  According to the transpiration body 3D having the above-described configuration, the same action and effect as the above-described transpiration body 3C can be obtained, and for example, there is one hole 8d formed in the bottom 8b of the pot body 8. Even so, the water diffuses uniformly with respect to the upper surface portion 7a.

  Fig.7 (a) is sectional drawing which shows the upper part of the transpiration body 3E which concerns on 6th Embodiment, FIG.7 (b) is a top view of the plate body of the transpiration body 3E. 7A is different from the transpiration body 3B shown in FIG. 4A in that it has a plate body 21 in which a groove portion 21d is further formed in the bottom plate portion 21a in place of the plate body 16. This is a point provided with a water diffusion portion 15E. The dish body 21 includes an annular groove portion 21d and a bottom plate portion 21a composed of a flat portion 21e other than the groove portion 21d, a peripheral wall portion 21b rising from a peripheral edge portion of the bottom plate portion 21a, and a plurality of hole portions 21f formed in the groove portion 21d. And a plurality of holes 21g formed in the flat portion 21e. In the dish body 21, each hole 21f formed in the groove 21d is smaller than the hole 21g formed in the flat portion 21e.

  According to the transpiration body 3E having the above-described configuration, the same functions and effects as the above-described transpiration body 3C can be achieved. Furthermore, water falls from the hole 21f of the groove 21d, and the water accumulated in the groove 21d and overflowing the flat part 21e also falls from the hole 21g of the flat part 21e. Therefore, water can be dropped from the entire bottom plate portion 21a, and water is more evenly diffused with respect to the upper surface portion 7a.

  Fig.8 (a) is sectional drawing which shows the upper part of the transpiration body 3F which concerns on 7th Embodiment, FIG.8 (b) is a top view of the bottom part of the bowl of the transpiration body 3F. The difference between the transpiration body 3F shown in FIG. 8 (a) and the transpiration body of each of the above embodiments is that the filter member and the dish body are not provided, and that the bowl 28 is devised in place of the bowl body 8. This is a point provided with a body 28. The pot body 28 includes an inverted frustoconical side portion 28a, a bottom portion 28b provided continuously with the lower end of the side portion 28a, and a flange portion 28c provided continuously with the upper end of the side portion 28a and suspended on the outer cylinder 6. have.

A plurality of holes 28f are formed in the groove 28d.

  According to 3F which has the said structure, by passing water through the soil layer 9 in the pot body 28, and the hole 28f of the bottom part 28b, it will be supplied to the transpiration | evaporation main-body part 7 in the state which water diffused. That is, in the transpiration body 3F, the bowl 28 corresponds to a water diffusion portion. Thus, the pot body 28 used for planting can also be used for the diffusion of water. Furthermore, water from the water supply port 4b can be used for a plurality of purposes. Furthermore, the design property is also improved by the plant 10 planted in the pot body 28.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. For example, in the above-described embodiment, a transpiration body having a cylindrical outer shape has been described. However, the present invention is not limited to this, and a transpiration body having a prismatic outer shape may be used. A transpiration | evaporation body will not be specifically limited if it is a shape which extends in the perpendicular direction under the water supply port 4b, and air passes. Moreover, although the said embodiment demonstrated the case where the header pipe | tube 4a of the water supply header 4 was provided above the transpiration | evaporation body 3, for example, a water supply header may be provided between a pot body and a water diffusion part. In this case, the water supply to the pot body is performed by means other than the water supply header. By planting a plant 10 of a type in which leaves hang down in a pot body, it is possible to cover the water supply header and improve the design.

  Moreover, in the said embodiment, although the transpiration | evaporation body is shown as what comprises a part of exterior, it attaches to the outer wall and window of a building, or each louver body of the louver apparatus which comprises these comprises Of course, it is possible to use a transpiration body.

  In addition, the transpiration body of the present invention adopts a circular cross section in the above embodiment, but the cross sectional shape is not limited to this, and is not limited to an ellipse, but a polygon such as a triangle, a rectangle or a rhombus, a half It is also possible to adopt a shape such as a circular shape or a star shape.

  In addition, the configuration of the filter member is not limited to the configuration of the filter member 11 or the filter member 11A as long as it includes a fiber layer that allows water to permeate through capillary action. Any shape of three-dimensional solid knitted fabric can be used as the filter member. Moreover, you may form a hole in the bottom part of the pots 8 and 28 at random. Furthermore, when providing a filter member or a plate, the bowl can be omitted. In this case, the water supply port 4b is disposed so as to allow water to flow into a region other than the gap between the surrounding portion 6b and the opening or hole formed in the dish body.
