Description

Air purification device using plants

Cross Reference to Related Applications

The present application claims benefits based on priority of korean patent application No. 2017-0120321, filed from 19.9.2017 to the korean intellectual property office, the contents of which are incorporated herein by reference.

Technical Field

The present invention relates to an air purification apparatus using plants.

Background

Plants remove pollutants from the air through photosynthesis, transpiration, interaction with microorganisms in the soil, and the like.

Therefore, recently, an air cleaning device for cleaning indoor air using plants has been developed, which passes the indoor air through a flowerpot in which plants are planted by forcibly circulating the indoor air through an air blowing device.

A conventional air cleaning apparatus using plants includes a frame provided in a conventional wall shape for forming an air passage, a plurality of flower pots provided on a front surface of the frame, and an air blowing device for providing blowing force to forcibly circulate ambient air through each of the plurality of flower pots and an inside of the air passage. The space between the support and the ports is configured to be ventilated so that air passing through the inside of each of the plurality of ports can be guided to the air passage.

When the air cleaning device is used to circulate indoor air, contaminants in the indoor air are absorbed into leaves and stems during the air passes through the flowerpot, forming overground parts of plants. The contaminants absorbed into the leaves and stems are used as metabolites of the plants, so some contaminants are removed and the remaining contaminants move to the roots to form the underground parts of the plants, thereby being removed in the process of being used as nutrients for soil microorganisms of the rhizosphere part.

However, in the conventional air cleaning apparatus using plants, since a planting area of plants related to air cleaning is limited to a front surface of a rack forming an air passage, it is limited to improve air cleaning efficiency by increasing the planting area of plants. Further, plants are only seen from the front, and thus the effect of the plants for decorative use is not good.

The embodiments described below are provided to fully convey the technical idea of the present invention to those skilled in the art. The invention is not limited to the embodiments presented and can also be embodied in other embodiments. In order to clarify the present invention, portions irrelevant to the description are omitted in the schematic drawings, and the sizes of components are enlarged in the schematic drawings for convenience.

As shown in fig. 1 to 4, according to one embodiment of the present invention, an air cleaning apparatus using plants includes a base 100 supported by a floor, an air guide pipe 200 having a cylindrical shape at the center of the base 100, an air blowing housing 300 provided on the air guide pipe 200, a plurality of flowerpots 400 radially distributed in multiple layers formed around the air guide pipe 200 between the air blowing housing 300 and the base 100.

The air guide duct 200 is provided to form an air passage 210 in a vertical direction, and a plurality of first ventilation parts 220 are provided at the circumference of the air guide duct 200. The first ventilation part 220 may be configured to pass through the hole of the air duct 200 such that the inside and the outside of the air passage 210 communicate with each other.

The base 100 may be provided in a hollow cylindrical shape, and the pulley 110 may be installed at the bottom of the base 100 to move the device.

The blow housing 300 is provided in a disk shape to cover the upper portion and the periphery of the upper portion of the air guide duct 200.

The plurality of flower pots 400 each form a pot shape in which one surface is opened and are radially distributed around the air guide tube 200 between the air-blowing housing 300 and the base 100 to form a plurality of layers such that the opened surface is radially outward. A second ventilating part 410 is provided in each port 400 for communicating with the first ventilating part 220 of the air guide pipe 200.

As shown in fig. 5 and 6, each flowerpot 400 may include an outer housing 400A supported by the air guide pipe 200, and an inner housing 400B detachably mounted on the outer housing 400A, and plants are planted in a state where soil is filled in the inner housing 400B.

The housing 400A may be provided in the shape of a hollow tub having an open front surface and blocked rear and circumferential surfaces.

The case 400A may be supported on the outer surface of the air duct 200 by having a curved rear surface corresponding to the curvature of the surface of the air duct 200.

Further, the housing 400A may contain water therein due to having a rear receiving space. A water introduction port 420 may be formed on an upper surface of the case 400A, and a drain portion 430 may be formed on a rear lower surface of the case 400A.

The drain part 430 is provided to communicate the inside and outside of the case 400A with each other, and may include an upward protrusion 431 and a downward protrusion 432 protruding upward and downward, respectively, from the lower surface of the case 400A.

The upward protrusions 431 may maintain the water level of the water supplied to the rear lower surface in the housing 400A at a predetermined level, and the downward protrusions 432 may be provided to be inserted into the water introduction ports 420 formed in the upper surface of the housing 400A of the lower pot 400. The water supplied to the housing 400A of each upper pot 400 may be supplied to the housing 400A of each lower pot 400 in a state of filling the rear bottom of the housing 400A according to the height of the upward protrusion 431 through the structure between the water introduction port 420 and the drain 430 and through the drain 430.

The inner case 400B may be provided in a tub shape with an open front surface, a blocked rear surface and a circumferential surface, and slidably inserted into the outer case 400A.

A planting space 440 of the flowerpot 400 is formed in the inner space of the inner housing 400B, and the flowerpot 400 has a pot shape of which the front surface of the planting space 440 is opened when the inner housing 400B is inserted into the outer housing 400A.

The inner case 400B may include a pair of opening and closing parts 450 at both sides of the front surface thereof. The pair of opening and closing members 450 may open and close the edge of the front surface of the inner case 400B and may be rotatably spliced to both sides of the front surface of the inner case 400B.

The opening and closing part 450 may be opened during the filling of the planting space 440 and shield the edge of the front surface of the inner case 400B in a state where the planting space 440 is filled with soil to prevent the soil in the planting space 440 from leaking out of the planting space 440. The plants planted in the planting space 440 may be exposed to the front of the flowerpot 400 through a space between the opening and closing parts 450 provided to close the edge of the front surface of the inner case 400B.

In addition, a support 460 configured to support the absorbent material 500 may protrude inward from the rear surface of the inner case 400B. Referring to fig. 10, the absorbent material 500 may be provided as a core configured to absorb and transport moisture, etc., and is inserted and fixed in the support 460 such that one end thereof extends between the outer case 400A and the inner case 400B and the other end thereof extends to the inside of the inner case 400B.

Accordingly, water supplied to the rear lower portion of the housing 400A may be transferred to the soil of the planting space 440 through the moisture absorbent material 500.

The second ventilating portion 410 of the port 400 may include a plurality of holes 411 and 412 provided through the rear surface of each of the outer and

inner cases

400A and 400B.

An air blowing means 330 is provided in the air blowing housing 300 to provide a blowing force to forcibly circulate air around the air cleaning device through each of the plurality of plant pots 400 and the inside of the air passage 210. The air blowing device 330 may include a blower 331.

The blow housing 300 may include a lower housing 310 and an upper housing 320. The blower 331 may be installed between the upper case 320 and the lower case 310, a through hole 311 is formed at the center of the lower case 310 such that the air passage 210 and the inside of the blow case 300 communicate with each other, and a water discharge hole 321 may be provided on the upper case 320.

Accordingly, as shown in fig. 9, when the blowing fan 331 operates, air around the air cleaning device is introduced into the air passage 210 through the first and second ventilating

parts

220 and 410 by the plurality of flowerpots 400. The air introduced into the air passage 210 moves to the upper portion of the air passage 210 and is discharged to the upper portion of the blow housing 300 through the water discharge hole 321. The flow of air is continuously repeated during the operation of the blower 331.

Accordingly, when the air cleaning device is driven in a soil-filled state and plants are planted in the plurality of flower pots 400, air around the air cleaning device forms a circulation flow through the soil of each flower pot 400 through the air passage 210, wherein the underground portion of the plants is located by the periphery of the above-ground portion of the plants planted in each flower pot 400.

In this case, contaminants in the indoor air are absorbed into leaves and stems forming the overground part of the plant during the air passes through the flowerpot 400. The contaminants absorbed into the leaves and stems are used as metabolites of the plants, so that some contaminants are removed and the remaining contaminants move to the roots to form the underground parts of the plants, thereby being removed in the process of being used as nutrients for soil microorganisms of the rhizosphere part.

Further, as described above, in the air cleaning apparatus according to the present embodiment, since the plurality of flower pots 400 are radially arranged around the air duct 200 to form a plurality of layers, the plant growing area where the cleaned air is provided by the amount of air passing through the air passage 210 is effectively increased.

In addition, in the treatment structure in which the flowerpot 400 radially forms a plurality of layers around the air guide pipe 200, the plants planted in the flowerpot 400 may be exposed in any direction around the air cleaning device. Thus, in the air cleaning apparatus, since the plants can be viewed from any direction around the apparatus, the usefulness of the plants, i.e., participating in cleaning air as a decorative use, can be improved.

Each of the plurality of ports 400 disposed around the air guide 200 may be supported adjacent to each other in a vertical direction and a circumferential direction, the port 400 of the highest layer may be supported by the air blowing housing 300, and the port 400 of the lowest layer may be supported by the base 100 so that air may be purified through the planting area without leakage.

As shown in fig. 7, in order to easily install a plurality of ports 400 on the air guide duct 200, a plurality of insertion grooves 230, which are separated from each other, may be provided in the air guide duct 200 in a circumferential direction, and insertion protrusions 470, which are inserted into the insertion grooves 230 and are slidable in a vertical direction, may be provided on a support surface of each of the ports 400 supported by the air guide duct 200.

Accordingly, the ports 400 can be easily mounted to the air guide pipes in a vertically stacked manner or separated from the air guide pipes 200 by the operation of sequentially inserting the insertion protrusions 470 into the insertion grooves or separating from the insertion grooves 230.

Further, as described above, since each flowerpot installed on the air guide duct 200 is arranged to be inclined outward from the radial direction, the front surface of the opening is in a state of being inclined outward from the radial direction, soil therein does not leak, and the ornamental effect of the plant can be enhanced in consideration of the phototaxis of the plant.

In addition, in order to stably support the inclined flowerpot 400, the lower surface of the lower housing 310 of the air-blowing housing 300 corresponds to the circumference of the air guide tube 200, and an upper surface support surface 312 for supporting the upper surface of the highest-level flowerpot 400 may be formed. An upper surface of the base 100 corresponding to the circumference of the air guide 200 may form a lower surface support surface 120 for supporting the lower surface of the flowerpot 400 of the lowest layer, and each of the upper surface support surface 312 and the lower surface support surface 120 may be provided as an inclined surface corresponding to the inclination of the flowerpot 400.

Further, the air cleaning device includes a water supply device 600 configured to supply water to the flowerpot 400.

As described above, the flowerpot 400 is provided such that water supplied to the upper flowerpot 400 through the water introduction port 420 and the drain 430 is distributed and supplied to the lower flowerpot 400, and the water supply device 600 includes a drawer-shaped pot 610 installed in the base 100 and slidable into the base 100; a pump 620 for pumping water in the tub 610, and a water supply pipe 630 configured to guide water pumped from the tub 610 by the pump 620 to be supplied into the air-blowing housing 300.

The water supply pipe 630 may be installed along the air passage 210 without a separate installation space.

The water supply device 600 may further include a water guide pipe 640 provided in the air-blowing housing 300 to guide the water guided to the air-blowing housing 300 to the uppermost flowerpot 400.

As shown in fig. 8, the water guide pipe 640 may include a plurality of water supply holes 641 formed in the lower housing 310 of the air-blowing housing 300 to communicate with the water introduction port 420 of the uppermost flowerpot 400, and fixing ports 642 provided such that the water supply pipe 630 withdrawn to the upper portion of the air passage 210 is fixed to the periphery of the water supply holes 641. A plurality of distribution pipes 631 distributed to the water supply holes 641 may be connected to the water supply line 630.

Accordingly, water drawn from the tub 610 is guided to the air blowing housing 300 along the water supply line 630, guided to the plurality of water supply holes 641 through the plurality of distribution pipes 631, and then the water guided to the plurality of water supply holes 641 is supplied to the flowerpot 400 at the uppermost stage through the water introduction port 420 of each flowerpot 400. The water supplied to the flowerpot 400 of the uppermost layer is distributed to the flowerpot 400 of the lowermost layer of the uppermost layer through the drainage part 430, and thus, any one of the pots 400 provided in the air cleaning device can be supplied with the water accordingly.

In addition, the air cleaning apparatus may include an air supply device 700 configured to supply ambient air into soil for planting filled in the flowerpot 400.

As shown in fig. 9 and 10, the air supply device 700 may include an air pump 710 installed on one side of the pot 610 of the base 100 and a plurality of air supply ducts 720 installed along the air passage 210 for supplying air pumped by the air pump 710 to the plurality of flower pots 400. In this case, the air supply duct 720 installed along the air passage 210 does not need to have a separate installation space either.

In the rear surfaces of the outer and

inner cases

400A and 400B of the flowerpot 400 (see fig. 5), escape holes 471 and 472 for withdrawing the outlet of each air supply duct 720 to the inner case 400B may be provided.

The escape holes 471 and 472 may be in internal communication with the lower portion of the inner case 400B, and thus, the air supply duct 720 may be in communication with the flowerpot 400 such that the outlet thereof faces the roots of the plants.

In addition, a diffuser 730 may be installed at an outlet of each air supply duct 720 for diffusing air discharged into the plant pot 400 through the air supply duct 720.

Therefore, in the air cleaning apparatus according to the present embodiment, when air is cleaned by the plants, air-containing contaminants around the air cleaning apparatus are continuously guided to the rhizosphere portion of each plant through the air supply duct 720, unlike the blowing operation of the air blowing device 330.

In this case, the air passing through the diffuser 730 may be uniformly introduced to the periphery of each rhizosphere portion in a state of being diffused into a fine stream to increase the staying time of the contaminants around the rhizosphere portion, so that the microorganisms in the rhizosphere portion may be continuously and smoothly contacted with the contaminants even when the air blown by the air blowing device 330 rapidly passes through the soil of the flowerpot. Therefore, the contaminant disintegration efficiency of the microorganism in the rhizosphere portion is improved.

In addition, since the flow direction of the air introduced to the roots of the plants by the air supply device 700 is opposite to the flow direction of the air passing through the flowerpot 400 by the air blowing device 330, the residence time of the air at the rhizosphere portion of each plant can be further increased, and thus, the efficiency of disintegration of contaminants in the air by microorganisms in the rhizosphere portion can be further improved.

As can be seen from the description, since a plurality of ports for purifying air are radially arranged around the air passageway, the air cleaning apparatus using plants according to one embodiment of the present invention can effectively increase the planting area of plants participating in air cleaning.

Further, since the plants providing air purification can be viewed from any direction around the air passageway, the air purification apparatus using plants can improve the usefulness of the plants, i.e., participate in purifying air as a decorative use.
