Conventionally, in this type of wall greening air purification device, a plurality of boxes in which plants are planted on the front side are arranged so as to be adjacent to each other, wall greening is achieved, and air to be purified sucked by a fan is ducted It is set as the structure sent to the back surface of each said box via. The air to be purified sent in is purified by passing through a plant growth base such as a soil layer filling each box.

Japanese Patent No. 5001148

The configuration of the conventional example described above has the following problems.
・ A large number of ducts are required to send the air to be purified into each box to be the greening part.
-In order to push the air to be purified discharged from the duct evenly into the box, a separate back panel for dispersion is required on the back side of the box.
・ The duct is exposed from the box and deteriorates over time, and maintenance of the duct becomes necessary.
-The duct space for the duct may be larger than the box that will be the greening part, so it cannot be installed close to the wall.

In addition, there are the following problems regarding the blowing of air to be purified.
(1) In order to send the air to be purified to the back side of the box, a space for installing a ventilation portion on the back side of the box is required.
(2) Since there is a ventilation part on the back of the box, it cannot be planted on the back side of the box.
(3) Since the pressure loss when the air to be purified passes through a plant growth base such as soil is large, a large fan is required for blowing air.
(4) Use of a large fan may increase noise.
(5) If the soil of the plant growth base decreases with age and a space is formed in the upper part, the air to be purified escapes from the upper part.
(6) Since wind comes out from the entire front surface, it is necessary to consider the installation location.

  The object of the present invention is that it is not necessary to provide a pipe or a ventilation layer for sending the air to be purified on the back surface, and it can be installed in a narrow space, and is configured to be planted on both the front side and the back side. It is also possible to provide a wall surface greening air purification apparatus that can reduce the noise and noise of the fan with less pressure loss.

  The wall surface greening air purification apparatus of the present invention penetrates in the plant growth base in a direction perpendicular to the plant growth surface of the plant growth base, and the ventilation resistance in the penetration direction is from other parts of the plant growth base. A small highly air-permeable soil part is provided, and the high air-permeable soil part is partitioned with a partition material and filled with a plant growth base material, and air to be purified is supplied to the highly air-permeable soil part. A blowing means for feeding was provided.

  According to this configuration, the air to be purified is sent from one end to the highly breathable soil portion by the blowing means. The air to be purified is purified in the process of passing through the highly breathable soil part. The purified air is discharged to the outside from the other end of the highly breathable soil part. When the air to be purified passes through the highly air permeable soil part, a part of the air is also diffused into the plant growth base part around the highly air permeable soil part and is purified here.

  The highly air permeable soil part penetrates in the vertical direction which is a direction perpendicular to the plant growth surface of the plant growth base, and in order to ventilate in this vertical direction, a pipe and a ventilation layer for sending air to be purified Need not be provided on the back. Therefore, the entire thickness of the wall surface greening air purification device can be reduced, and it is not necessary to open a space for piping on the back surface. Thereby, it can install also in a narrow space. Moreover, the structure planted to both the front side and the back side is also employable. When ventilating in a direction perpendicular to the plant growth surface of the plant growth base, the thickness of the ventilation is thick, but a highly breathable soil part smaller than the other parts of the plant growth base is provided, and the inside is ventilated, Ventilation resistance is small. Therefore, the fan can be reduced in size and noise can be reduced.

In this invention, you may use the plant growth base material with a particle size coarser than the plant growth base material which comprises the said other part of the said plant growth base for the said high air permeability soil part.
Thereby, ventilation resistance can be made smaller than the other part of a plant growth base, using a highly breathable soil part for the growth of a plant, utilizing a highly breathable soil part.

In the present invention, the highly breathable soil part may be entirely surrounded by the other part of the plant growth base.
The highly breathable soil part is not suitable for plant growth compared to other parts of the plant growth base, but if the whole highly breathable soil part is surrounded by other parts of the plant growth base, the highly breathable soil part Since the part is not exposed to the plant growth surface, a substantial planting area can be taken.

In this invention, the partition material may be a material that has air permeability but cannot pass through the plant growth base material that constitutes the other part of the plant growth base.
By making a partition material into the said material, it can prevent that the plant growth base material of the circumference | surroundings of a highly air permeable soil part enters into a highly air permeable soil part.

In this invention, you may provide the said high air permeability soil part in the multiple places in the said plant growth base.
According to the installation place of the wall surface greening air purification apparatus, the highly air-permeable soil part can be provided in arbitrary plural places.

In this invention, the highly air permeable soil part is a ventilation unit in which the plant growth base material is filled in a bag-like body made of the tubular partition material and an air permeable end face material that closes both ends of the partition material. It may be.
In this case, a highly breathable soil part can be easily provided in the plant growth base.

When the penetration direction is the vertical direction, the ventilation means is provided along the upper end or the lower end of the plant growth base and communicates with one end of the highly air-permeable soil part, and the ventilation chamber And a fan that sends air to be purified to the highly air-permeable soil part.
By providing the ventilation chamber, the air to be purified can be fed into the plurality of highly breathable soil portions with one fan.

Further, the air blowing means may be a fan that is provided adjacent to an end portion of each highly air-permeable soil portion and sends air to be purified to the highly air-permeable soil portion.
In this case, the air to be purified can be sent directly to the highly air-permeable soil part by a fan, so that a duct or the like is unnecessary.

  The wall surface greening air purification apparatus of the present invention penetrates in the plant growth base in a direction perpendicular to the plant growth surface of the plant growth base, and the ventilation resistance in the penetration direction is from other parts of the plant growth base. A small highly air-permeable soil part is provided, and the high air-permeable soil part is partitioned with a partition material and filled with a plant growth base material, and air to be purified is supplied to the highly air-permeable soil part. Since the air blowing means is provided, it is not necessary to provide piping and ventilation layers for sending the air to be purified on the back surface, it can be installed in a narrow space, and it is planted on both the front side and the back side. The configuration can also be adopted, and the fan can be downsized and the noise can be reduced with less pressure loss.

It is a top view which shows the example of arrangement | positioning of a different highly air permeable soil part.

  A first embodiment of the present invention will be described with reference to FIGS. As shown in the longitudinal sectional view of FIG. 1, this wall surface greening air purification device 1 is a wall-shaped plant growth base 2 in which each surface of the top, bottom, left and right (the direction perpendicular to the paper is the left-right direction) is surrounded by an outer peripheral frame 7 The plant 20 is planted on the plant growth surfaces 3 and 4 composed of the front and back surfaces of the plant growth base 2. The plant growth surfaces 3 and 4 are each covered with a mesh material 5. The mesh material 5 is made of, for example, a wire mesh in which plated wires are knitted vertically and horizontally.

  The plant growth base 2 occupies most of the plant growth base 2 and has a plurality of through-holes 6 penetrating vertically, and a highly-breathable soil provided in the through-holes 6. Part 2b. The plant growth soil portion 2a constituting the plant growth surfaces 3 and 4 becomes the substantial plant growth base 2 on which the plant 20 is planted. Each highly air-permeable soil part 2b is arrange | positioned along with the center part between a front surface and a back surface, for example like FIG.

  In FIG. 1, for example, lightweight soil is used as the plant growth base material A of the plant growth soil portion 2a. Specifically, in addition to natural soil, various commonly distributed materials such as organic soil improvement materials such as bark compost, peat moss and cocoa dust, or inorganic soil improvement materials such as perlite and vermiculite are appropriately combined. It may be used. Further, it may be a sponge-like or felt-like material having air permeability. In addition, ceramic or the like may be used.

  Moreover, as the plant growth base material B of the highly air-permeable soil portion 2b, a material having a coarser particle diameter than the plant growth base material A of the plant growth soil portion 2a, for example, a soil base material such as perlite is used. Therefore, the air permeability resistance in the length direction of the through-hole 6 is smaller in the highly breathable soil portion 2b than in the plant growing soil portion 2a.

  For example, a ventilation unit 8 shown in FIG. 3 is used for the highly breathable soil portion 2 b of the plant growth base 2. The ventilation unit 8 includes a plant growth base material B (inside a bag-like body 9 made of a mesh material composed of a tubular partition material 9a and upper and lower end surface materials 9b, 9c that close both ends of the partition material 9a. (Not shown). In the example of the figure, the outer shape of the bag-like body 9 is a cylindrical shape, but it may be a prismatic shape or other shapes. By using such an aeration unit 8, the highly air permeable soil part 2 b can be easily provided in the plant growth base 2.

  The partition material 9 a has a coarseness that prevents the surrounding plant growth base material A from entering the bag-like body 9. However, it is not necessary to limit the roots of the plant 20 planted in the plant growth soil portion 2a to extend into the highly breathable soil portion 2b. Further, the roughness of the end face materials 9b and 9c is such that the internal plant growth base material B does not leak to the outside and does not prevent the wind from passing through. Specifically, when the particle diameter of the plant growth base material B to be filled is relatively coarse (5 mm or more), the partition material 9a has a coarseness of about 1 to 2 mm, and the end face materials 9b and 9c have a coarseness. The length is about 3 mm.

  The length of the ventilation unit 8 is not particularly limited in order to match the vertical dimension of the plant growth base 2. When the ventilation unit 8 is long, it may be supported by the outer frame 7 every predetermined length (for example, 1 m). FIG. 4 shows an example in which it is supported by a mesh-like partition plate 11. FIG. 5 shows an example in which a plurality of support rods 12 (for example, two) are supported.

  As shown in FIG. 1, an air blowing means 13 for sending air to be purified to the highly air-permeable soil portion 2 b is provided below the plant growth base 2. The air blowing means 13 is provided along the lower end of the plant growth base 2 and communicates with the lower end of each highly breathable soil portion 2b. It consists of a fan 15 that feeds air for purification. The casing constituting the ventilation chamber 14 is provided with an air inlet 14a for air to be purified.

  According to the configuration of the wall surface greening air purification device 1, by operating the fan 15, the air to be purified outside the device is sucked from the suction port 14 a by the fan 15, and each high ventilation is passed through the ventilation chamber 14. It is sent from the lower end to the soil property part 2b. The air to be purified is purified in the process of passing through the highly breathable soil portion 2b. The purified air is discharged to the outside from the upper end of the highly breathable soil portion 2b. When the air to be purified passes through the highly breathable soil portion 2b, a part of the air diffuses into the plant growing soil portion 2a and is also purified here.

  The highly air-permeable soil portion 2b is provided inside the plant growth base 2 so as to penetrate in the vertical direction perpendicular to the plant growth surfaces 3 and 4 of the plant growth base 2. Therefore, it can plant not only on the front side of the plant growth base 2 but also on the back side. Although the high air permeability soil part 2b is not suitable for the growth of the plant 20 as compared with the plant growth soil part 2a, the entire outer periphery of the high air permeability soil part 2b is surrounded by the plant growth soil part 2a as in this embodiment. If it exists, since the highly air-permeable soil part 2b is not exposed to the plant growth surfaces 3 and 4 of the plant growth base 2, a substantial planting area can be taken.

  Further, since the air blowing means 13 for sending the air to be purified to the highly breathable soil portion 2b is provided, it is necessary to send the air to be purified to the highly breathable soil portion 2b from a location far away from the wall surface greening air purification device 1. And there is no need for piping for blowing. It is not necessary to provide a separate panel or the like for dispersion on the back side. Therefore, the entire thickness of the wall surface greening air purification device 1 is not so thick. If the ventilation chamber 14 connected to the lower end of each highly air permeable soil part 2b is provided as in this embodiment, the air to be purified can be sent to the plurality of highly air permeable soil parts 2b by one fan 15. .

  When the highly air-permeable soil part 2b is provided, the pressure loss of the air for purification when passing through the plant growth base 2 can be suppressed. Thereby, size reduction of the fan 15 of the ventilation means 13 is attained. By using the small fan 15, noise can be suppressed. Since the place where the wind comes out is determined in advance by the location of the highly breathable soil portion 2b, even if there is a space above the plant growth base 2 due to the loss of the plant growth base material A, the air to be purified escapes from there. There is nothing. Most of the purified air comes upward from the upper end of the highly breathable soil portion 2b. Since there is a plant growth base 2a made of the plant growth base material A having a small particle diameter around the highly air-permeable soil part 2b, the air-tightness of the high air-permeable soil part 2b is ensured, and the wind from the plant growth surfaces 3 and 4 Hard to leak. Therefore, it is easy to install the wall surface greening air purification device 1 near a place where a person passes.

  Furthermore, since the highly breathable soil part 2b has good drainage, it is useful for draining the plant growth base 2. Since the static pressure is lowered by promoting the drainage of the plant growth base 2, the strength of the outer peripheral frame 7, which is a constituent material of the wall surface greening air purification device 1, can be lowered. Thereby, weight saving and cost saving can be achieved.

The actions and effects of the wall surface greening air purification device 1 of this embodiment will be summarized below.
(1) There is no need to install a ventilation part on the back side of the plant growth base 2.
(2) Since the highly air-permeable soil part 2b used as a ventilation part is arrange | positioned inside the plant growth base 2, it can plant not only on the front side of the plant growth base 2, but on the back side.
(3) The pressure loss of the air to be purified when passing through the plant growth base 2 can be suppressed, and the fan 15 can be downsized.
(4) By using the small fan 15, noise can be suppressed.
(5) Since the location where the wind comes out is determined in advance by the location of the highly air-permeable soil portion 2b, even if a space is formed above the plant growth base 2, air for purification does not escape from there.
(6) Since the purified wind comes out from the upper part of the wall greening air purification device 1, it is easy to install near the place where people pass.

The modification of 1st Embodiment is shown below.
As shown in FIG. 6, the air blowing means 13 may be disposed on the upper side of the plant growth base 2. In this case, the air to be purified is fed into the highly breathable soil portion 2b from the lower end by sucking air from the upper end of the highly breathable soil portion 2b through the ventilation chamber 14 by the fan 15. In this case, the same effect as the example of FIG. 1 can be obtained.

  Further, as shown in FIG. 7A, the plant growth surfaces 3 and 4 of the plant growth base 2 may be covered with a wall greening panel 16. The wall greening front panel 16 may be one in which a hole from which the plant 20 exits is previously formed, or a protruding piece 16a formed by cutting a part of the outer periphery as shown in FIG. May be bent at a portion of the outer periphery where there is no break, thereby opening a hole 16b through which the plant 20 exits.

  8 and 9 show a second embodiment of the present invention. The air blowing means 13 of this embodiment has a configuration in which air to be purified is sent to each highly breathable soil portion 2b by a fan 15 provided for each highly breathable soil portion 2b. In the case of this example, the fan 15 is provided above each highly breathable soil portion 2b, and the air inlet 17a (to be purified) is placed in the lower box 17 provided below each highly breathable soil portion 2b. FIG. 9) is provided. In the lower box 17, a water receiver 18 that receives water W dripping from the highly breathable soil portion 2 b is provided. In addition, in FIG. 9, although the supplementary figure which shows the schematic shape of the fan 15 (for example, DC fan) is displayed together, in this supplementary figure, the state installed in the wall surface greening air purification apparatus 1 is shown. The fan 15 is displayed in a different posture.

  According to the configuration of the wall surface greening air purification device 1, by operating the fan 15, the air to be purified outside the device is sucked from the suction port 17a and passes through the highly breathable soil portion 2b from the bottom to the top. . Since the air to be purified is sent directly to the highly breathable soil portion 2b by the fan 15, the ventilation chamber 14, the other piping, and the like in the first embodiment are unnecessary.

  When the length of the ventilation unit 8 to be the highly breathable soil portion 2b is long, as in FIG. 10, the middle part of the ventilation unit 8 in the length direction is surrounded by the mesh-like partition plate 11 as shown in FIG. It is good to let you support. Although not shown, the ventilation unit 8 may be supported by a plurality of (for example, two) support rods 12 (FIG. 5). Moreover, as shown in FIG. 11, you may cover the plant growth surfaces 3 and 4 of the plant growth base 2 with the wall surface greening panel 16 (refer FIG. 7).

  In each of the above examples, the highly breathable soil portion 2b is formed into a vertically long and slender bar shape. However, as shown in the plan view of FIG. 12, the highly breathable soil portion 2b is aligned with the direction in which the plant growth surfaces 3 and 4 are aligned. It may be layered. In this case, the same effect as that of the rod shape can be obtained.
