1 to 3, the air purification system 1 using plants according to an embodiment can remove carbon dioxide and volatile organic compounds (VOCs) compared to general air purifiers, and visually Through plants, the user's emotional stability can also be improved. The air purification system 1 may include a plant unit 11, a plurality of plant pots 12, an air conditioning unit 13, a water tank unit 15, and a control unit 19.

A plurality of plant pots 12 may be detachably disposed on the plant part 11 . By replacing the individual plant pots 12 according to the growth degree and condition of the plant, it is possible to improve the convenience of managing the plant. For example, the plant part 11 may be located on the side of the air conditioner 13 . According to this structure, by additionally disposing another plant part 11 on the other side of the air conditioner 13, air is supplied to the plurality of plant parts 11 using one air conditioner 13. it is possible to supply For example, the plant part 11 may be located above the water tank part 15 . According to this arrangement, since water falling from the plant part 11 can be easily guided to the water tank part 15, the structure in which water circulates between the water tank part 15 and the plant part 11 can be simplified more easily. can provide The plant part 11 may include a plurality of sub plant parts 111 , a light source 112 , and a rear space 113 .

A plurality of sub plant parts 111 may be arranged in a vertical direction in front of the plant part 111 . Each of the plurality of sub-plant parts 111 may include a mounting plate 1111, a water tray 1113, and an inlet 1115.

A port 1111a into which a plant pot 12 can be inserted may be formed in the mounting plate 1111 . The edge portion of the pot 1111a may support the flange portion of the plant pot 12 . The mounting plate 1111 may have a shape inclined forward at a predetermined angle, for example. According to this shape, the plant pot 12 can be more easily attached and detached, and the plant growth space can be prevented from being limited only by the space between the pair of vertically adjacent mounting plates 1111, while the plant part The front of (11) can be made to look rich with plants.

The drip tray 1113 is located below the mounting plate 1111 and can contain water so that at least a portion of the plant pot is submerged in water. The water tray 1113 may include a receiving wall 11131 (see FIG. 5) for accommodating water therein. On the other hand, as shown in FIG. 3, the receiving wall 11131 may form part of the exterior of the water tray 1113, but, unlike this, a case forming the exterior of the water tray 1113 exists separately, and the case It should be noted that the receiving wall 11131 may be separately provided inside the .

For example, at the bottom of the accommodating wall 11131, a connecting portion 11131a extending to the mounting plate 1111 of the sub-plant 111 positioned adjacent to the lower side of the plurality of sub-plants 111 is formed. can be formed According to the connecting portion 11131a, it is possible to block air from being circulated between the pair of mutually adjacent sub-plant parts 111. According to this structure, the filtering efficiency can be improved by preventing the air discharged from the air conditioner 13 from being directly discharged to the outside without being filtered through the plant pollen 12 .

On the other hand, if necessary, a bypass hole (not shown) omitting the sub plant part 111 (see FIG. 1) may be formed on one side, for example, the uppermost side of the plant part 11 (see FIG. 3). . According to the bypass hole, since the air discharged from the air conditioning unit 13 can reduce the pressure loss generated in the process of passing through the sub-plant 111, the air can be discharged at a high air volume or speed. In addition, a fragrant substance may be disposed around the bypass hole.

A bent portion 11131b bent toward the port 1111a may be formed in a portion of the receiving wall 11131 located on the side of the inlet 1115 (see FIG. 3 ) through which air is introduced. In other words, the bent portion 11131b is a portion located at an end of the receiving wall 11131 toward the inlet 1115 and may have a shape bent toward a direction in which air is discharged. According to the bent portion 11131b, by supporting the side of the plant pot 12 inserted obliquely, the plant pot 12 can be stably placed. In addition, according to the shape of the bent portion (11131b), the effect of reducing the problem that the water vapor formed by evaporation of the water accommodated in the drip tray 1113 flows back to the rear space (113) can also be expected.

The inlet 1115 is a hole through which air discharged from the air conditioner 13 is introduced through the rear space 113 . For example, the space between the mounting plate 1111 and the drip tray 1113 may be formed such that the port 1111a and the remaining portion except for the inlet 1115 are closed. According to this structure, the air discharged from the air conditioning unit 13 may be introduced into the space between the mounting plate 1111 and the water tray 1113 and then discharged to the outside through the port 1111a.

On the other hand, in the above-mentioned space, the water accommodated in the water tray 1113 is evaporated, and humid air exists. From this point of view, the above-mentioned space may be referred to as "evaporation space". Since the evaporation space can perform a function of filtering air pollutants such as fine dust by the moisture contained therein, it functions as a filter. Therefore, the evaporation space can pre-filter the air before passing through the plant pollen 12, and air pollutants collected by moisture in this way can be removed by falling into the water contained in the water tray 1113. To the extent that air pollutants are removed in advance, the purifying ability of the plant pollen 12 can be secured, and consequently, the purifying ability of the entire air purifying system 1 can be improved.

For example, the area of the inlet 1115 may be larger than that of the port 1111a. In this way, according to the evaporation space having a narrower outlet than the inlet, the air is pressurized in the evaporation space, and the pressurized air is discharged to the outside at a high speed, increasing the evaporation rate of the water contained in the water tray 1113. can make it

The light source 112 is disposed in front of the plant part 11, functions as a mood light, emits light helpful for the growth of the plant pot 12, and/or is controlled by the controller 19 Light notifying the user of specific information may be emitted. The light source 112 may be disposed on the lower side of the sub-plant part 111, for example, on the lower side of the water tray 1113. According to this arrangement, light can be supplied to the plant pot 12 mounted on the sub-plant part 111 disposed adjacent to the lower side without a support structure such as a bracket for separately installing the light source 112 .

The rear space 113 may be provided behind the plant part 11 . Air introduced into the rear space 113 from the air conditioner 13 may be discharged to the outside through the plurality of sub-plant parts 111 . For example, in the rear space 113, there may be no barrier rib that blocks the flow of air from the outlet 138 of the air conditioning unit 13 to the inlet 1115 of the sub-plant unit 111. In other words, the rear space 113 may be one space not partitioned by partition walls. According to the rear space 113, it can function as a buffer space that prevents air evaporated from the plurality of sub-plant parts 111 from directly flowing into the air conditioning unit 13. In addition, as shown in FIG. 2, when the flow direction of the air flowing into the rear space 113 through the outlet 138 is perpendicular to the flow direction of the air discharged from the rear space 113, the sub-plant part It is possible to reduce the problem of air being discharged by deflecting to either the left or right side of (111). In other words, it is possible to improve the uniformity of air discharged from the entire air conditioning system 1 by reducing a problem in which air is deflected and discharged to a side of the sub-plant 111 closer to the air conditioner 13.

The air conditioning unit 13 may introduce air from the outside and flow the air so that the introduced air passes through the plant unit 11 and is discharged to the outside. The air conditioner 13 may include a suction plate 131 , a filter 133 , a blowing fan 135 , an air quality detection sensor 137 , an outlet 138 , and a display 139 .

The suction plate 131 is a part forming a part of the outer surface of the air conditioner 13, and may include an air intake hole formed on an upstream side of air sucked in from the outside. According to the suction plate 131, it is possible to prevent a foreign substance larger than the diameter of the air intake hole from being introduced into the air conditioner 13.

The filter 133 may remove air pollutants included in the air passing through the air intake hole of the suction plate 131 . The filter 133 may include a HEPA filter (High Efficiency Particulate Air filter, HEPA filter) for removing fine particles such as fine dust. According to the filter 133, the filtering effect by the plant part 11 can be further increased by improving the quality of the air discharged to the plant part 11.

The blowing fan 135 is located on the downstream side of the filter 133 and can form a flow of air discharged toward the plant part 11 . For example, a plurality of blowing fans 135 may be disposed along the longitudinal direction of the air conditioning unit 13 shown in FIG. 1 to uniformly discharge air through the plurality of sub-plant parts 111. there is. As shown in FIG. 2 , the blowing fan 135 may supply air to the side of the plant part 11 through the rear space 113 . For example, when the plant unit 11 is located on both sides of the air conditioning unit 13, a plurality of blower units 135 and a plurality of outlets 138 may be provided to supply air to both sides, respectively. there is.

The air quality detection sensor 137 may detect the level of air pollutants such as fine dust and transmit the detected level to the control unit 19 . The air quality detection sensor 137 may be installed, for example, inside the air conditioning unit 13. Alternatively, the outside of the air conditioning unit 13, the plant unit 11, or the water tank unit 13 It should be noted that it can be installed inside or outside of the Unless otherwise stated, the air quality detection sensor 137 may be any means widely known to those skilled in the art, and a detailed description thereof will be omitted.

At least one discharge port 138 may be formed in the partition plate P partitioning between the air conditioning unit 13 and the plant unit 11 . For example, a plurality of discharge ports 138 may be spaced apart in the vertical direction of the partition plate P to correspond to the number and position of the blowing fans 135 . According to the partition plate P and the discharge port 138, while minimizing the pressure loss of the air discharged to the plant part 11 by the blowing fan 135, the air from the plant part 11 to the air conditioning unit 13 backflow can be prevented. According to this structure, it is possible to prevent damage to various electronic components provided inside the air conditioning unit 13 due to inflow of humid air around the plant unit 11 .

The display 139 may output visual information about the state of the plant part 11, the air conditioning unit 13, the water tank unit 15, or ambient air quality to the user. For example, (i) information on the open/closed state of the passage through which water circulates in the plant part 11, (ii) the level of various air pollutants including fine dust, current temperature and humidity, or current airflow amount B, (iii) information about the level of water accommodated in the water tank unit 15 can be informed to the user. For example, the display 139 may be installed on the front of the air conditioner 13 as shown in FIG. 1, but this is only an example, and not the air conditioner 13, but the plant part ( 11) or the water tank unit 15 can also be installed.

The water tank unit 15 is a space for storing water to be supplied to the plant unit 11, and may be located on one side, for example, the lower side of the plant unit 11. According to such a structure, the path of water circulating with the plant part 11 can be further reduced. The water tank unit 15 may include a water injection unit 153 and a water level check window 155 .

The water injection unit 153 is a service hole through which water can be filled into the water tank unit 15 . The water injection unit 153 may be formed above the water tank unit 15 so that a user can easily fill the water.

The water level check window 155 is a transparent portion through which the amount of water stored in the water tank 15 can be checked from the outside without opening the water inlet 153 of the water tank 15 . The water level check window 155 may be formed long in the vertical direction on the front or side surface of the water tank unit 15, for example.

The control unit 19 can control the air discharge amount of the air conditioner 13 and/or the water circulation of the plant unit 11 . The control unit 19 is, for example, disposed in the air conditioning unit 13 with respect to the partition plate P, so that the humid air evaporated from the sub-plant 111 flows into the control unit 19, and the control unit 19 (19) can be avoided. A detailed description of the controller 19 will be described later with reference to FIG. 6 .

According to the structure described above, the air sucked in from the outside is (i) primarily purified by the suction plate 131, (ii) secondarily purified by the filter 133, (iii) mounting plate (iv) the received soil-based material and activated carbon provided in a wet state inside the plant pot 12, and planting It can be purified quaternarily by the root of the plant. In particular, according to the plant pollen 12, unlike conventional air purifiers, carbon dioxide and even volatile organic compounds (VOCs) can be removed. In addition, as designed, the removal efficiency of carbon dioxide and volatile organic compounds can be remarkably improved by having the purification action by the plant pollen 12 performed at the very end and other purification functions being performed in multiple steps in advance. .

4 is an exploded perspective view of a plant pot according to an embodiment.

Referring to FIG. 4 , a plant pot 12 according to an embodiment may include a pot base 121 and a pot cover 122 as a portion where plants are planted.

The pot base 121 can accommodate soil-based materials such as hydro balls and activated carbon such as charcoal. Soil-based material and activated carbon contain moisture, provide moisture and nutrients to the roots of plants in contact therewith, and collect air pollutants contained in the air passing through in contact therewith. An upper portion of the pot base 121 is open, and a plurality of holes may be formed on the side and lower surfaces of the water tray 1113 to allow water to flow into the inside.

The pot cover 122 may be provided to shield at least a portion of the top of the pot base 121 . For example, the pot cover 122 may be detachably provided to the pot base 121 . The pot base 121 may include a support plate 1221 and a fixing leg 1222 .

The support plate 1221 may prevent loss of soil-based material or the like accommodated in the pot base 121 when the plant pot 12 is taken out from the holder plate 1111 .

The fixing leg 1222 is a part protruding from the lower surface of the support plate 1221, and is inserted between soil substrates and the like accommodated inside the pot base 121, so that the pot cover 122 is attached to the pot base 121. can be prevented from escaping.

5 is a schematic diagram illustrating an internal structure of an air purification system using plants according to an embodiment.

Referring to FIG. 5 , the air purification system 1 includes a supply passage 17 and a return passage 18 for guiding water circulating between the plurality of sub-plant parts 111 and the water tank part 15. can do. The supply passage 17 and the recovery passage 18 may be installed, for example, on a rear space 113 (see FIG. 2 ) located behind the plant part 11 .

The supply passage 17 may guide water supplied from the water tank unit 15 to the drip tray 1113 . The supply passage 17, for example, supplies water to the drip tray 1113 of the sub-plant 111 located at the uppermost side among the plurality of sub-plant parts 111, and the sub-plant part disposed downward ( 111), water may be supplied sequentially. In other words, water trays 1113 of each of the plurality of sub-plant parts 111 may be sequentially filled with water according to the order in which they are arranged from the upper side to the lower side.

The recovery passage 18 may directly or indirectly guide the water recovered from the drip tray 1113 toward the water tank unit 15 . The recovery passage 18 may include a connection passage 181 and a bypass passage 182 .

The connection passage 181 may guide water from the upper sub-plant 111 to the lower sub-plant 111 among the plurality of sub-plants 111 . On the other hand, the "flow path" expressed herein means a path through which fluid flows, and it should be clarified that a pipe or the like surrounding the fluid does not have to be present, as shown in FIG. 5 and the like. For example, when the water trays 1113 of each of the two sub-plant parts 111 adjacent to each other are installed to overlap each other in the vertical direction, a hole drilled in the bottom of the upper water tray 1113 forms a connection passage 181 Those skilled in the art will be able to fully understand that it will be able to function as.

The bypass flow path 182 allows water accommodated in any one of the plurality of sub-plant parts 111 to bypass the other sub-plant parts 111, so that the water tank part 15 is directly can be guided to flow. A valve 1821 capable of switching a communication state of the bypass passage 182 may be provided on the bypass passage 182 . For example, the valve 1821 may be a manual on-off valve that can be directly adjusted by a person, or an electronic on-off valve that can be automatically operated by the control unit 19 . For example, a plurality of valves 1821 may be provided corresponding to the number of water trays 1113 . The valve 1821 maintains a closed state during normal operation and is opened when internal inspection or replacement is required, so that the water contained in each water tray 1113 can be quickly discharged.

The water tank unit 15 may include a pump 151 for supplying water to the supply passage 17 and a water level detection sensor 157 for detecting the water level accommodated therein.

The water level detection sensor 157 may be, for example, a sensor that detects whether a specific water level is exceeded by detecting whether or not fluid is contacted in an on/off form. In this case, a plurality of water level sensors 157 may be installed along the height direction of the water tank unit 15 to detect various water levels. As another example, it may be a sensor that detects a continuously changing water level inside the water tank unit 15, such as a laser distance sensor. Meanwhile, it should be noted that various types of sensors known to those skilled in the art may be applied in addition to the above-described methods.

The drip tray 1113 provided in the plurality of sub-plant parts 111 includes a receiving wall 11131 for accommodating water therein and a guide partition wall 11132 installed in the space surrounded by the receiving wall 11131. can include

The guide partition wall 11132 may have a lower height than the rest of the receiving wall 11131 . According to this structure, when the water accommodated in the water tray 1113 is supplied to the extent that the water level exceeds a certain level, the excess supplied water flows beyond the guide partition wall 11132 rather than other parts. Here, the water flowing beyond the guide partition wall 11132 may be guided to the drip tray 1113 of the other sub-plant part 111 located below it through the recovery passage 18 . According to this structure, water of a constant water level can be filled in each water tray 1113 without having an electronic sensor or control means.
