Description

A vertical hydroponic system that maximizes root growth within the interior space and allows for the vertical expansion of the cultivation area.

[0001] The present application relates to a vertical hydroponic cultivation system, and more specifically, to a vertical hydroponic cultivation system implemented to maximize root growth within an internal space and enable the vertical expansion of the cultivation space. In particular, the vertical hydroponic cultivation system is further configured to improve the plant growth environment through reflection.

[0002] Hydroponics is a method of plant cultivation in which water and nutrients necessary for crop growth are not supplied from the soil, but rather from a nutrient solution dissolved in appropriate proportions.

[0003] Hydroponics is currently widely used because it has the advantage of protecting plants from various pests and diseases by supplying a nutrient solution diluted with various growth promoters and nutrients, and artificially accelerating the growth rate of plants to obtain a large yield in a short period of time without using pesticides harmful to the human body.

[0004] Due to these advantages, hydroponics is being attempted even in cities with large populations but limited arable land. Crops harvested through hydroponics in cities can be supplied to consumers at low prices through short supply channels between suppliers and consumers who have established themselves in the city.

[0005] Hydroponics can be classified into horizontal hydroponics, in which plants are arranged horizontally relative to the ground, or vertical hydroponics, in which plants are arranged vertically.

[0006] Conventional horizontal hydroponic systems had several drawbacks: due to the nature of the equipment, water remains stagnant, leading to poor cleanliness if filtration devices were not properly installed or maintenance was neglected; additionally, the horizontal system required a large installation space and was difficult to move. Furthermore, to maximize the use of limited space, cultivation beds were stacked, resulting in plants in the lower layers having their sunlight blocked by the upper beds, which hindered their uniform growth.

[0007] Furthermore, conventional vertical hydroponic systems had additional limitations in terms of nutrient supply through pipes.

[0008] Meanwhile, the aforementioned background technology is technical information that the inventor possessed for the derivation of the present application or acquired during the process of deriving the present application, and it cannot be considered as prior art disclosed to the general public prior to the filing of the present application.

[0009] One aspect of the present application provides a vertical hydroponic cultivation system implemented to maximize root growth within an internal space, enable vertical expansion of the cultivation space, and improve the plant growth environment through reflection.

[0010] Another aspect of the present application is to provide an irrigation system that minimizes damage to the piping line supplying nutrient solution to the vertical hydroponic system.

[0011] The technical problems of the present application are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below.

[0012] A vertical hydroponic cultivation system according to one embodiment of the present application may include: a plurality of plant cultivation units providing a cultivation space for arranging plants in a vertical direction; a nutrient solution collection unit connected to the lower side of each of the plurality of plant cultivation units to collect nutrient solution falling through the plant cultivation units; a support unit installed to support the plant cultivation units; and a lighting unit installed on the support unit facing the plant cultivation units to irradiate light for plant cultivation in the direction of the plant cultivation units.

[0013] In one embodiment, the plant cultivation unit may include: a cartridge formed in the shape of a square tube with an open front end to form a slot so that nutrient solution can fall along the internal space, and the interior being coated with a waterproof material; two slot holders extending in the vertical direction along one side and the other side of the slot, which is the front opening of the cartridge; a water barrier plate, one side and the other side of which are stacked and coupled in a sliding manner from the lower side of the slot through the slot holders to seal the slot and prevent leakage of the nutrient solution falling along the internal space of the cartridge; a flowerpot installed on the water barrier plate to cultivate a plant; and a water collector, one side and the other side of which are stacked and coupled alternately with the water barrier plate from the lower side of the slot through the slot holders to seal the slot and prevent leakage of the nutrient solution falling along the internal space of the cartridge, and which collects the nutrient solution falling along the internal space of the cartridge to supply nutrients to the roots of the plant being cultivated in the flowerpot. The above water collector may be equipped with a drainage hole for supplying nutrients from the collected nutrient solution to the roots of plants installed on a water barrier plate stacked below, at least a portion of the collected nutrient solution.

[0014] In one embodiment, the water barrier plate may include: a water barrier plate formed in a square flat plate shape corresponding to the left and right widths of the slot; two first slot fastening pieces extending from one side and the other side of the water barrier plate so as to be engaged with the two slot holders; and a port guide installed on the water barrier plate so as to allow the flowerpot pot to be seated at a certain angle.

[0015] In one embodiment, the front surface of the water level plate may be made of a color capable of reflecting light irradiated from the lighting unit to the side and / or rear surface of the plant installed in the flowerpot.

[0016] In one embodiment, the front surface of the above-mentioned plate may be white.

[0017] In one embodiment, the front surface of the water level plate may be made of a white reflector so that light irradiated from the lighting unit can be reflected to the rear surface of the side of the plant.

[0018] In one embodiment, the pot guide may be configured so that the flowerpot can be seated at a certain angle between 30 and 60 degrees.

[0019] In one embodiment, the pot guide may be installed on the water level plate so that the flowerpot pot can be seated at a 45-degree angle.

[0020] In one embodiment, some of the plurality of pot guides within the plant cultivation section may have a different angle at which a flowerpot is seated compared to others, and the angle at which a flowerpot is seated may be designed according to the relative positional relationship between the position of the water barrier plate and the lighting section in the plant cultivation section.

[0021] In one embodiment, the water collector may include: a water collection plate formed in a rectangular flat plate shape corresponding to the left and right widths of the slot; two second slot fastening pieces extending from one side and the other side of the water collection plate so as to be engaged with the two slot holders; and a water collection part installed at the rear end of the water collection plate exposed to the internal space of the cartridge to collect nutrient liquid falling along the internal space of the cartridge.

[0022] In one embodiment, the collection unit may include: a collection bottom surface formed as a flat plane so as to collect a portion of the nutrient solution falling along the internal space of the cartridge while the roots of the plant exposed from the flowerpot are settled; a collection side surface formed on one side and the other side of the collection bottom surface at the rear end of the collection plate to form a space for receiving the nutrient solution; and a drain formed on the collection bottom surface so as to allow the nutrient solution to be discharged downward from the collection bottom surface.

[0023] In one embodiment, the drain may include a plurality of first drains formed on the bottom surface of the water collection so that nutrient solution can be discharged downward from the bottom surface of the water collection; and a second drain formed at the center of the front end of the bottom surface of the water collection, opposite to the rear end of the water collection plate, so that nutrient solution can be discharged downward from the bottom surface of the water collection.

[0024] In one embodiment, the first drain is formed to extend longer than the second drain so that it can be gradually settled from the front end to the rear end according to the growth process of the root, and a plurality of them may be arranged in a radial structure centered on the second drain formed at the position where the root first settles.

[0025] In one embodiment, the bottom surface of the water collection surface is installed so as to be inclined such that the rear end is positioned above the front end to allow the nutrient solution to flow forward, and at the same time, it may be formed by bending into a "V" shape to allow the nutrient solution to flow towards the center.

[0026] In one embodiment, the bottom surface of the water collection can be formed shorter than the front-to-back length of the internal space of the cartridge to open a portion of the rear end of the internal space of the cartridge so that the liquid can be discharged downward even when the drain is completely sealed.

[0027] In one embodiment, the plant cultivation unit may further include a bridging bracket in the shape of a square tube, wherein an upper fastening groove is formed on the upper side for engaging the lower side of the cartridge and a lower fastening groove is formed on the lower side for engaging the upper side of the cartridge, so as to allow two or more of the cartridges to be stacked and connected in the vertical direction.

[0028] In one embodiment, the lighting unit may include: a plurality of sliding rails extending in the front-rear direction along the upper side of the support unit; a module support frame extending in the left-right width direction and connected to enable sliding movement in the front-rear direction along the plurality of sliding rails; an actuator installed on the support unit and connected to the module support frame, which moves the module support frame toward the direction of the plant cultivation unit or away from the plant cultivation unit as it extends or contracts; a plurality of lighting modules spaced apart and installed along the lower side of the module support frame, each facing the plurality of plant cultivation units, to irradiate light toward the direction of the plant cultivation units; and a remote controller connected to the actuator via a network to remotely drive the actuator.

[0029] In one embodiment, a vertical hydroponic cultivation system according to another embodiment of the present application may further include an irrigation system installed on the support member to supply nutrient solution to the plurality of plant cultivation members.

[0030] In one embodiment, the irrigation system may include: a first piping line for delivering nutrient solution from a nutrient solution storage tank to a plant cultivation unit; a second piping line connected to a nutrient solution collection unit and delivering residual nutrient solution remaining after absorption in the plant cultivation unit from the nutrient solution collection unit to the nutrient solution storage tank; a first pump for applying hydraulic pressure to move the nutrient solution contained in the nutrient solution storage tank along the first piping line; and a valve module for supplying the nutrient solution branched from the first joint pipe along the first piping line to each of the plurality of plant cultivation units.

[0031] According to one aspect of the present application described above, the system is designed to allow for the expansion of two or more cartridges constituting a layer unit to increase cultivation yield. While existing vertical hydroponic systems consist of a single cartridge, limiting the utilization of cultivation space, this system is designed to expand into a multi-layer structure, enabling more efficient space utilization. This allows for the cultivation of more crops within the same installation area, and since multiple plant pots can be mounted on a 4M-long vertical cartridge, the cultivation yield per unit area can increase by more than double compared to existing systems. Furthermore, the expansion structure of the cartridge can be flexibly adjusted as needed, allowing for the creation of an optimal cultivation environment tailored to the growth characteristics of various crops.

[0032] To optimize root growth, a water collector was used instead of an absorbent material to ensure effective contact between the roots and the nutrient solution within the cartridge. While absorbent materials are commonly used in hydroponic systems to promote smooth root growth, they can lead to issues over time, such as uneven water supply or hindering root development as the roots grow. Accordingly, this system incorporates a water collector to ensure that the entire root system always comes into uniform contact with the nutrient solution. In particular, this collector is designed to concentrate the supply of nutrient solution to the base of the roots, even if the position of the root base changes as the roots grow. As a result, the roots receive a continuous and sufficient supply of nutrient solution as they grow, maintaining a uniform growth rate. Furthermore, efficient nutrient absorption across the entire root system leads to improved crop quality and yield. Additionally, thanks to these structural characteristics, the roots can grow longer and healthier, thereby improving the overall growth environment for the crop.

[0033] Additionally, the front surface of the water barrier plate can be formed as a reflector. Through this structure, photosynthesis can be carried out smoothly on the side and / or back of the leaves of the plant (1), and has the effect of improving the overall growth rate of the plant (1). In particular, the light environment can be improved so that the plant (1) can grow more evenly, thereby maintaining uniformity in cultivation quality.

[0063] Hereinafter, preferred embodiments of the present application will be described in more detail with reference to the drawings.

[0064]

[0065] FIG. 1 is a diagram showing the schematic configuration of a vertical hydroponic cultivation system according to one embodiment of the present application.

[0066] Referring to FIG. 1, a vertical hydroponic system (10) according to one embodiment of the present application includes a plurality of plant cultivation sections (100), a nutrient solution collection section (200), a support section (300), and a lighting section (400).

[0067] A plurality of plant cultivation units (100) provide a cultivation space for cultivating hydroponically cultivable plants (1) by arranging them side by side in an up-and-down vertical direction. Each plant cultivation unit (100) has a multi-layered structure in a vertical direction and is formed to accommodate a plurality of plants (1) inside. Additionally, a supply path is formed in the plant cultivation unit (100) to supply nutrient solution, and the nutrient solution is designed to be uniformly supplied to the space where each plant (1) is cultivated.

[0068] The nutrient solution collection unit (200) is connected and installed at the lower side of each of the plurality of plant cultivation units (100) and is configured to collect the nutrient solution falling through the plant cultivation units (100). The nutrient solution collection unit (200) is positioned so that the nutrient solution flowing in the vertical direction can be efficiently recovered without being lost to the outside.

[0069] In various embodiments of the present application, some or all of the recovered nutrient solution may be connected to a storage tank or a resupply system so that it can be reused.

[0070] The support member (300) provides an installation structure for stably supporting a plurality of plant cultivation units (100). The support member (300) is formed to provide structural stability so that the plant cultivation units (100) can be stacked in a vertical direction and to distribute the load of the plant cultivation units (100) in a balanced manner. In some embodiments, the support member (300) includes an adjustable structure to facilitate the placement and adjustment of the plant cultivation units (100) according to various environments.

[0071] The lighting unit (400) is installed on the support unit (300) facing the plant cultivation unit (100) and is configured to irradiate light for the cultivation of the plant (1) in the direction of the plant cultivation unit (100). The lighting unit (400) maintains a balance of illumination so that the plant (1) can optimize photosynthesis and can promote the growth of the plant (1) by irradiating light of a specific wavelength. In some embodiments, the lighting unit (400) includes an LED light source and may be equipped with a light intensity control function and an automatic illumination control function.

[0072] A vertical hydroponic cultivation system (10) according to one embodiment of the present application having the configuration described above is configured to efficiently cultivate a number of plants (1) in a limited space. In addition, the nutrient solution supply and recovery system is optimized so that uniform water and nutrient supply is possible while minimizing the amount of nutrient solution used. Furthermore, by arranging the lighting unit (400), the growth rate of the plants (1) can be improved and a uniform cultivation environment can be provided, thereby maximizing productivity.

[0073]

[0074] Figures 2 to 4 are drawings showing the plant cultivation section of Figure 1.

[0075] FIG. 2 is a schematic diagram of a plant cultivation unit according to various embodiments. FIG. 3 illustrates a structure in which a plurality of plant cultivation units are connected to each other and extended. FIG. 4 illustrates a structure in which a plurality of plant cultivation units are connected to each other through a bridging bracket according to various embodiments.

[0076] Referring to FIGS. 2 to 4, the plant cultivation unit (100) includes a cartridge (110), a slot holder (120), a water barrier plate (140), a flowerpot (150) (see FIG. 8), and a water collector (160).

[0077] The cartridge (110) has a body formed by cutting longitudinally on one side to form a slit connecting the outside and the inside. The width of the slit can be defined as the distance between the slit surfaces located on the one side.

[0078] The cartridge (110) has a slot (130) with an open shear formed so that the nutrient solution can fall along the internal space, and is formed in the shape of a square tube. The interior of the cartridge (110) is coated with a waterproof material so that the nutrient solution can be managed efficiently without leakage. This structure functions to guide the remaining nutrient solution to flow naturally downward after the nutrient solution is supplied to the roots (2) of the plant (1).

[0079] The cartridge (110) provides a slot holder (120). The slot holder (120) is located inside the cartridge (110) relative to the slit surface, and a portion of the slot holder (120) is connected to the slot surface and has another portion protruding toward the slot surface and a different side opposite to the connected portion. The gap between the portion and the other portion of the slot holder (120) provides a slot hole.

[0080] The slot holder (120) is formed to extend vertically along one side and the other side of the slot (130), which is the front opening of the cartridge (110). The slot holder (120) provides a guide so that the water barrier plate (140) and the water collector (160) can be installed sequentially on the cartridge (110), and supports stacking in a sliding manner so that these components can be stably joined.

[0081] The water barrier plate (140) is sequentially stacked and connected in a sliding manner from the lower side of the slot (130) through the slot holder (120), thereby sealing the slot (130) and preventing leakage of the nutrient solution falling along the internal space of the cartridge (110). In addition, the water barrier plate (140) divides the internal space to provide an individual cultivation environment for the plant (1) in each section and serves to regulate the supply of an appropriate amount of nutrient solution.

[0082] The water barrier plate (140) provides space for a pot holder that secures a flowerpot (150). The water barrier plate (140) and the water collector (160) form a unit structure of the structure, and a plurality of pairs of water barrier plates (140) and water collectors (160) can provide a holder structure. Since one flowerpot (150) is placed per unit structure, it may be referred to as a holder unit. On one side (e.g., the front) of the water barrier plate (140), a holder front surface is formed that protrudes relatively compared to one side of the water barrier plate, and on the other side (e.g., the rear) of the water barrier plate (140), a holder rear surface is formed that is recessed relatively compared to the other side of the water barrier plate.

[0083] A flowerpot (150) is installed on a water barrier (140) to allow the plant (1) to be grown. The flowerpot (150) is designed to be inserted into a hole in the water barrier (140) and serves as a support for the plant (1). Additionally, the flowerpot (150) is configured so that the roots (2) of the plant (1) can expand into the internal space of the cartridge (110), thereby promoting healthy growth of the plant (1).

[0084] The water collector (160) is alternately stacked and coupled with the water barrier plate (140) from the lower side of the slot (130) through the slot holder (120). The water collector (160) seals the slot (130) together with the water barrier plate (140) to prevent leakage of the nutrient solution, and at the same time collects the nutrient solution falling along the internal space of the cartridge (110) so as to supply nutrients from the nutrient solution to the roots (2) of the plant (1) being cultivated in the flowerpot (150).

[0085] In some embodiments, the length of the collector (160) may correspond to the length from the front to the rear of the cartridge (110). As shown in FIG. 8a, the collector (160) may be configured with a length such that, when coupled to the slot (130), its rear end contacts or is positioned close enough to the rear wall of the cartridge (110). Then, no nutrient solution flows between the rear of the collector (160) and the rear wall of the cartridge (110), or flows much less, for example, finely, compared to the flow of nutrient solution through other holes of the collector (160).

[0086] In some other embodiments, the length of the collector (160) may be configured to be shorter than the length from the front to the back of the cartridge (110). As shown in FIG. 8b, the collector (160) coupled to the slot (130) may form a gap between its back and the back wall of the cartridge (110).

[0087] A plant cultivation unit (100) according to one embodiment of the present application having the configuration described above induces the nutrient solution to flow naturally along the internal space, thereby allowing the roots (2) of the plant (1) to grow in an optimal environment. In addition, through the sliding stacking structure of the water barrier plate (140) and the water collector (160), maintenance is easy and installation and replacement can be conveniently performed. Through this structure, the plant cultivation unit (100) can maximize the efficiency of supplying and recovering the nutrient solution and improve the overall performance of the hydroponic cultivation system.

[0088]

[0089] A plant cultivation unit (100) according to one embodiment of the present application having the configuration as described above may further include a bridging bracket (170) so that two or more cartridges (110-1, 110-2) can be stacked and connected in the vertical direction as shown in FIGS. 3 and 4.

[0090] The bridging bracket (170) is formed in the shape of a square tube, and an upper fastening groove (171) is formed on the upper side for engaging the lower side of the cartridge (110), and a lower fastening groove (172) is formed on the lower side for engaging the upper side of the cartridge (110).

[0091] The upper fastening groove (171) is configured so that the lower part of the upper cartridge (110) can be stably inserted. Through this, the upper cartridge (110) can be firmly joined while aligned with the bridging bracket (170), and the stacked structure can be maintained.

[0092] The lower fastening groove (172) is formed so that the upper part of the cartridge (110) located at the bottom can be inserted, thereby allowing the lower cartridge (110) and the upper cartridge (110) to be connected in an integrated structure. The shape and size of the lower fastening groove (172) are designed to exactly match the cross-section of the cartridge (110), thereby enabling stable stacking without shaking.

[0093] The stacked structure using such bridging brackets (170) allows the cultivation area to be expanded in the vertical direction even in a limited space and serves to maximize the space utilization of the vertical hydroponic system (10). In addition, the bridging brackets (170) maintain the vertical alignment of the cartridges (110), thereby ensuring that the nutrient solution flow in the stacked structure remains constant and performing the function of reinforcing the stability of the system.

[0094] A bridging bracket (170) according to one embodiment of the present application having the configuration described above enables the implementation of a multi-layered vertical hydroponic system (10) and maintains the connection between cartridges (110) in a more robust and integrated structure, thereby having the effect of optimizing the cultivation environment.

[0095] Figures 7 and 8 are drawings showing the water barrier of Figure 2.

[0096] FIG. 7a is a perspective view of the water barrier plate of FIG. 2, FIG. 7b is a side view of the water barrier plate of FIG. 2, FIG. 7c is a top view of the water barrier plate of FIG. 2, FIG. 7d is a front view of the water barrier plate of FIG. 2, and FIG. 7e is a rear view of the water barrier plate of FIG. 2. FIG. 8a illustrates the process of supplying nutrient solution when a relatively long water collector is installed according to various embodiments. FIG. 8b illustrates the process of supplying nutrient solution when a relatively short water collector is installed according to various embodiments.

[0097] Referring to FIGS. 7 and 8, the water barrier plate (140) includes a water barrier plate (141), a first slot fastening piece (142), and a port guide (143).

[0098] The water barrier plate (141) is formed in the shape of a square flat plate corresponding to the left and right width of the slot (130). The water barrier plate (141) serves to seal the internal space of the cartridge (110) and prevents the nutrient solution from leaking out. In addition, the water barrier plate (141) maintains a constant flow along the path through which the nutrient solution flows, thereby ensuring that the roots (2) of each plant (1) receive appropriate moisture and nutrients.

[0099] The front surface of the above-mentioned water level plate may be configured to function as a reflector capable of reflecting light irradiated from the above-mentioned lighting unit to the side and / or rear surface of a plant installed in the above-mentioned flowerpot.

[0100] The reflector of the barrier plate may be made of a specific color that reflects light. The front surface of the barrier plate may be made of various specific colors capable of reflecting light irradiated from the lighting unit to the side and / or rear of the plant installed in the flowerpot.

[0101] In one embodiment, the front surface of the above-mentioned plate may be white.

[0102] For example, the front of the water level plate (141) is made of a white reflector so that light irradiated from the lighting unit (400) can be reflected to the rear of the side of the plant (1).

[0103] These water barrier plates (141) perform the function of ensuring that light emitted from the lighting unit (400) reaches the rear part of the plant (1) uniformly. In a typical vertical hydroponic system (10), since the light is mainly directed toward the front part of the plant (1), photosynthesis may be relatively reduced at the rear part of the leaves due to a lack of light. To compensate for this, the front surface of the water barrier plate (141) is formed with a white reflector with excellent reflective performance so that light can be effectively scattered and reflected.

[0104] Through this structure, photosynthesis can be carried out smoothly on the sides and / or backs of the leaves of the plant (1), and has the effect of improving the overall growth rate of the plant (1). In particular, the light environment can be improved so that the plant (1) can grow more evenly, thereby maintaining uniformity in cultivation quality.

[0105] In addition, the water level plate (141) with a white reflector also serves to efficiently utilize the amount of light from the lighting unit (400). Previously, some of the light irradiated from the lighting unit (400) did not reach the plant (1) and scattered into the surrounding space, resulting in wasted energy. However, in this embodiment, the loss of light is minimized through the reflector, and more concentrated lighting is made possible.

[0106] A water-blocking plate (141) according to one embodiment of the present application having the configuration described above can improve the overall cultivation efficiency of a vertical hydroponic system (10) by maximizing the lighting effect and inducing uniform growth of a plant (1).

[0107] The first slot fastening piece (142) is formed to extend from one side and the other side of the barrier plate (141) and is configured to engage with two slot holders (120). When the barrier plate (140) is inserted into the slot (130), the first slot fastening piece (142) engages with the slot holders (120) to stably secure the barrier plate (140). Through this structure, the barrier plate (140) is firmly fastened to the slot (130), while also providing a structure that allows for easy separation and replacement as needed.

[0108] A pot guide (143) is installed on the water level plate (141) so that the flowerpot (150) can be seated at a certain angle.

[0109] In one embodiment, the pot guide (143) may be configured so that the flowerpot pot (150) can be seated at a certain angle between 30 and 60 degrees. In addition, in some embodiments, the pot guide (143) is installed on the water barrier plate (141) so that the flowerpot pot (150) can be seated at a 45-degree angle.

[0110] The pot guide (143) functions to accurately fix the position of the flowerpot (150) and guides the stem and leaves of the plant (1) to grow in an optimal direction. The angle of the pot guide (143) is designed with one or more of the following in mind: effectively receiving light from the lighting unit, and minimizing contact and collision with the stems and leaves growing on surrounding plants (1) that have settled in other flowerpots (150).

[0111] Additionally, the pot guide (143) ensures that the flowerpot (150) is firmly fixed to the water barrier plate (141), thereby allowing the plant (1) to be maintained stably.

[0112] A water barrier plate (140) according to one embodiment of the present application having the configuration described above can systematically organize the internal structure of the plant cultivation unit (100), thereby improving the maintainability of the vertical hydroponic cultivation system (10) and maximizing the cultivation efficiency of the plant (1). In addition, the 45-degree angle arrangement of the flowerpot (150) using the pot guide (143) allows the plant (1) to receive uniform light and has the effect of increasing the utilization of the cultivation space.

[0113]

[0114] In additional embodiments, some of the pot guides (143) among the plurality of pot guides (143) in the plant cultivation section may have a different angle at which the pot pot is placed compared to some of the pot guides (143). Here, the angle at which the pot pot (150) is placed may be designed so that the amount of light irradiated to the plant placed through the pot pot (150) in the pot guide (143) increases according to the relative positional relationship between the position of the water barrier plate and the lighting section in the plant cultivation section. Then, compared to the case where the angles of all pot guides (143) in the plant cultivation section are the same, an increased amount of light can be irradiated to the plant placed in some or all of the pot guides (143).

[0115] For example, if the lighting unit (400) is positioned higher than the cartridge (110), a barrier plate (140) with a relatively large angle port guide (143) installed on the relatively lower layers of the cartridge (110), and a barrier plate (140) with a relatively small angle port guide (143) installed on the relatively higher layers of the cartridge (110) can be installed through a slot structure. For example, the angle of the port guide (143) located on the lowest layer of the cartridge (110) may be the largest, and the angle of the port guide (143) located on the highest layer of the cartridge (110) may be the smallest.

[0116] Figures 9 and 10 are drawings showing the water collector of Figure 2.

[0117] Referring to FIGS. 9 and 10, the water collector (160) includes a water collection plate (161), a second slot fastening piece (162), and a water collection part (163).

[0118] The water collection plate (161) is formed in the shape of a rectangular flat plate corresponding to the left and right widths of the slot (130). The water collection plate (161) is alternately combined with the water barrier plate (140) to prevent the nutrient solution falling along the internal space of the cartridge (110) from leaking out. Additionally, the water collection plate (161) may have an internal slope structure to allow the nutrient solution to move smoothly downward, thereby inducing the nutrient solution to be distributed more uniformly.

[0119] The second slot fastening piece (162) is formed to extend from one side and the other side of the water collection plate (161) and is configured to engage with two slot holders (120). The second slot fastening piece (162) allows the water collector (160) to be stably fixed by engaging with the slot holders (120) when the water collector (160) is inserted into the slot (130). Through this, the water collector (160) is designed to maintain a constant position while being easy to replace and maintain when necessary.

[0120] The collection section (163) is installed at the rear end of the collection plate (161) so as to be exposed to the internal space of the cartridge (110). The collection section (163) effectively collects the nutrient solution falling along the internal space of the cartridge (110) and ensures that the nutrient solution is evenly supplied to the roots (2) of each plant (1). The collection section (163) creates a constant drop so that the nutrient solution can spread evenly throughout the roots (2), and in this process, the effect of increasing oxygen supply can also be expected. Additionally, the shape of the collection section (163) can be designed so that the falling nutrient solution flows smoothly along the surface of the collection section (163), thereby allowing the nutrient solution sprayed in the form of water droplets to reach the roots (2) of the plant (1) more effectively.

[0121] In one embodiment, the water collection section (163) may include a water collection bottom surface (1631), a water collection side surface (1632), and a drain (1633).

[0122] The water collection bottom surface (1631) is flat and installed at the rear end of the water collection plate (161) so that the roots (2) of the plant (1) exposed from the flowerpot (150) can settle, and at the same time collect some of the nutrient solution falling along the internal space of the cartridge (110). The water collection bottom surface (1631) provides a sufficient area for the roots (2) to settle stably and serves to induce natural expansion as the roots (2) grow. In addition, the nutrient solution is designed to temporarily remain on the water collection bottom surface (1631) to maximize the opportunity for the roots (2) to absorb it.

[0123] Here, the bottom surface of the water collection area (1631) is installed at an angle such that the rear end is positioned higher than the front end so that the liquid can flow forward, and at the same time, it is formed by bending it into a "V" shape so that the liquid can flow towards the center.

[0124] The bottom surface of the water collection area (1631) is formed such that the rear end is positioned higher than the front end, thereby inducing the nutrient solution to flow naturally forward. Through this structure, the nutrient solution remains on the bottom surface of the water collection area (1631) for a certain period of time, allowing the roots (2) of the plant (1) to absorb sufficient moisture. Additionally, the sloped structure ensures that the excessive nutrient solution does not stagnate in a specific area but flows smoothly, thereby preventing the roots (2) from becoming excessively wet.

[0125] Additionally, the bottom surface of the water collection area (1631) is formed by bending it into a "V" shape so that the nutrient solution can naturally gather towards the center. Through this structure, the nutrient solution flowing down from the bottom surface of the water collection area (1631) can be effectively introduced into the drain (1633), and the flow of the nutrient solution can be distributed uniformly. In particular, the "V" shaped structure has the effect of minimizing waste of the nutrient solution by inducing the nutrient solution to flow along a specific path without leaking out to the sides of the bottom surface of the water collection area (1631).

[0126] A water collection bottom surface (1631) according to one embodiment of the present application having the configuration described above provides an optimized structure that allows the roots (2) of a plant (1) to absorb sufficient moisture while the nutrient solution flows in a certain direction. In addition, through a "V" shaped structure, the flow of the nutrient solution is efficiently controlled, thereby having the effect of improving the overall water circulation system of the vertical hydroponic system (10).

[0127] And, the bottom surface of the water collection area (1631) is formed shorter than the front-to-back length of the internal space of the cartridge (110) in order to open a part of the rear end of the internal space of the cartridge (110) so that the liquid can be discharged downward even when the drain (1633) is completely sealed.

[0128] The water collection bottom surface (1631) has a structure that opens a portion of the rear end of the internal space of the cartridge (110) so that the nutrient solution can be smoothly discharged downward without stagnation even if the drain (1633) becomes blocked due to the growth of the roots (2). To this end, the length of the water collection bottom surface (1631) is formed to be shorter than the front-to-back length of the internal space of the cartridge (110), thereby securing a certain open space at the rear.

[0129] Through this open structure, even if the drain (1633) is blocked while the nutrient solution is flowing over the bottom surface (1631), it can naturally fall downward through the rear opening. This allows the nutrient solution to circulate smoothly even if the drain (1633) is partially blocked or completely closed, thereby preventing the roots (2) of the plant (1) from falling into an overwatered state.

[0130] In addition, the rear open structure allows the roots (2) to expand into the rear space as they grow, thereby enabling the roots (2) of the plant (1) to grow in a wider and more balanced shape. This not only induces healthy growth of the roots (2) but also allows the nutrient supply path to be continuously maintained, thereby providing a stable hydroponic environment even during long-term use.

[0131] A water collection bottom surface (1631) according to one embodiment of the present application having the configuration described above has the effect of improving the overall stability and maintainability of a vertical hydroponic system (10) by solving the problem of nutrient stagnation that may occur due to blockage of the drain (1633) and optimizing the natural growth of roots (2) and the supply of nutrient solution.

[0132] The water collection side (1632) is installed on one side and the other side of the water collection bottom surface (1631) at the rear end of the water collection plate (161) and forms a space for accommodating nutrient solution. The water collection side (1632) serves to protect the nutrient solution supplied to the water collection bottom surface (1631) so that it does not easily leak out to the outside and the root (2) can absorb sufficient nutrient solution. Additionally, the water collection side (1632) functions to guide the nutrient solution to flow in a specific direction, thereby helping the nutrient solution to spread more evenly throughout the root (2).

[0133] A drain (1633) is formed in the bottom surface of the water collection area (1631) so that the nutrient solution can be discharged downward from the bottom surface of the water collection area (1631). The drain (1633) prevents more than a certain amount of nutrient solution from accumulating on the bottom surface of the water collection area (1631) and prevents the roots (2) from falling into an overwatered state. Additionally, the drain (1633) can be designed with an optimal size and position so that the nutrient solution can naturally move to the water collection area below, thereby maintaining smooth circulation of the nutrient solution inside the cartridge (110).

[0134] A water collection unit (163) according to one embodiment of the present application having the configuration described above provides an optimized structure that allows the roots (2) of a plant (1) to absorb nutrient solution more effectively, and induces healthy growth of the roots (2). In addition, by discharging excess nutrient solution through the drain (1633), it has the effect of maintaining an appropriate moisture balance within the hydroponic system (10) and maintaining a smooth flow of nutrient solution.

[0135] A water collector (160) according to one embodiment of the present application having the configuration described above optimizes the flow of nutrient solution within the cartridge (110) so that the roots (2) of the plant (1) can absorb the nutrient solution more uniformly. In addition, by maximizing the dispersion effect of the nutrient solution through the water collection section (163), it has the effect of improving the growth rate of the roots (2) and increasing cultivation efficiency.

[0136] Figure 11 is a drawing showing the configuration of the drain of Figure 9.

[0137] Referring to FIG. 11, the drain (1633) includes a plurality of first drains (16331) and second drains (16332).

[0138] The first drain (16331) is a plurality of drains formed on the bottom surface of the water collection area (1631) so that the nutrient solution can be discharged downward from the bottom surface of the water collection area (1631). The first drain (16331) is arranged at regular intervals and designed so that the nutrient solution can be discharged uniformly. This ensures that the nutrient solution does not accumulate excessively in a specific area and can be naturally delivered to the cultivation area on the lower floor. Additionally, the first drain (16331) is configured so that even if a certain part becomes clogged during the growth process of the roots (2), smooth drainage is possible through other drains.

[0139] Here, the first drain (16331) is designed to be gradually settled from the front end to the rear end according to the growth process of the root (2), and is formed to be extended longer than the second drain (16332).

[0140] The first drain (16331) is formed to be long so that it can gradually extend backward as the roots (2) of the plant (1) grow, thereby allowing nutrient solution to be continuously supplied to the ends of the roots (2). Initially, the roots (2) are short and concentrated at the front end, but as they grow, they gradually extend backward; therefore, the first drain (16331) is formed to be long up to the rear end to account for this.

[0141] Additionally, multiple first drains (16331) are arranged in a radial structure centered around the second drain (16332). This radial structure serves to guide the nutrient solution to flow naturally along the growth direction of the root (2). In other words, the arrangement of the drains is optimized so that the nutrient solution reaches evenly to the tip of the root (2), thereby allowing the root (2) to grow in a balanced state.

[0142] The first drain (16331) according to one embodiment of the present application having the configuration described above has the effect of improving the growth environment of the plant (1) by optimizing the structure of the drain in consideration of the growth pattern of the root (2). In addition, through a radial arrangement structure, the nutrient solution can be efficiently supplied according to the growth direction of the root (2), thereby functioning to improve the overall cultivation efficiency of the vertical hydroponic system (10).

[0143] The second drain (16332) is formed at the center of the front end of the water collection bottom surface (1631) opposite the rear end of the water collection plate (161) so that the nutrient solution can be discharged downward from the water collection bottom surface (1631). The second drain (16332) is positioned at the center of the front part of the water collector (160) to allow the nutrient solution to be discharged more intensively. In addition, the second drain (16332), together with the first drain (16331), guides the nutrient solution to flow in a certain direction, thereby enabling the nutrient solution supply and recovery system to operate more efficiently.

[0144] A drain (1633) according to one embodiment of the present application having the configuration described above provides a structure optimized to allow the nutrient solution to flow smoothly, and ensures that drainage is maintained smoothly even if the drain is clogged during the growth process of the root (2). In addition, by arranging the second drain (16332), the nutrient solution can be discharged intensively, thereby inducing the root (2) of the plant (1) to absorb the nutrient solution more effectively.

[0145] Referring to FIG. 12, the method of collecting and supplying nutrient solution by the water collector (160) according to the present application is described as follows.

[0146] Fig. 12a is a diagram illustrating the supply of nutrient solution during the early growth stage of a plant. Fig. 12b is a diagram illustrating the supply of nutrient solution during the mid-growth stage of a plant. Fig. 12c is a diagram illustrating the supply of nutrient solution during the late growth stage of a plant. Fig. 12d is an image showing the root condition and internal situation during the late growth stage of Fig. 12c.

[0147] The nutrient solution paths (3-1, 3-2, 3-3) illustrated in FIG. 12 are exemplary representations of various nutrient solution paths according to location, in which the nutrient solution is supplied by falling through a collector on the upper floor, and it will be obvious to a person skilled in the art that in the embodiments of the present application, the actual supply of nutrient solution is not necessarily implemented only through the nutrient solution paths (3-1, 3-2, 3-3).

[0148] First, as illustrated in FIG. 12a, in the early stages of growth of the plant (1), the length of the root (2-1) is relatively short, so the root (2-1) covers only a portion (S1) of the first drain (16331) and the second drain (16332). As a result, the nutrient solution paths (3-1, 3-2, 3-3) flowing along the inside of the cartridge (110) can fall as they are with almost no influence from the root (2-1), and the nutrient solution is discharged relatively freely rather than being evenly distributed over the entire plant root. At this time, since the root has not grown sufficiently, the flow of the nutrient solution does not significantly affect root absorption, and the nutrient solution can flow down naturally without direct contact.

[0149] Subsequently, when entering the mid-growth stage shown in FIG. 12b, the root (2-2) grows further and, as its length increases, covers a certain portion (S2) of not only the first drain (16331) but also the second drain (16332). Accordingly, the nutrient solution paths (3-1, 3-2, 3-3) flowing along the inside of the cartridge (110) have a portion of the path (3-1) blocked by the root (2-2), and the nutrient solution paths (3-2, 3-3) can be discharged only through the space not covered by the root. In this process, as the root grows, the flow of the nutrient solution is gradually restricted, and the root and the nutrient solution come into natural contact, thereby increasing the effect of the root's absorption of water and nutrients.

[0150] Next, as the plant enters the latter stage of growth shown in FIG. 12c, the roots (2-3) grow further until they completely cover the first drain (16331) and cover most of the second drain (16332) (S3). In the latter stage of plant growth, the roots (2-3) grow long enough to pass through the holes (16332, 16331), so as shown in FIG. 12d, a significant portion of the open parts of the holes (16331, 16332) is blocked by the roots (2-3). The length of the roots can grow so that they penetrate the drain of the water collector (160) and the other end of the roots protrudes outside the water collector (160). As a result, although the supply of nutrient solution through the nutrient solution paths (3-1, 3-2) is mostly blocked by the roots (2-3), the nutrient solution can fall through the part not covered by the roots (2-3) in the hole (16331) as shown in FIG. 12c, allowing the nutrient solution paths (3-3) to flow.

[0151] In other words, as plants grow, the density of the roots naturally increases, blocking the drainage holes. Consequently, the path for the nutrient solution to flow is restricted, forming a structure where the solution is supplied intensively to the tips of the roots.

[0152] The structural features of the water collector (160) provide the effect of automatically changing the supply location of the nutrient solution according to the plant's growth stage. That is, as the plant grows, the blockage of the drainage hole gradually progresses, and the nutrient solution path moves further backward. This movement of the nutrient solution path induces the nutrient solution to maintain direct contact with the tip of the root throughout the root's growth. As a result, it provides the important effect of ensuring that the nutrient solution is supplied at an optimal location according to the root's development status, rather than being supplied evenly to the entire root according to the plant's growth stage.

[0153] Consequently, the water collector (160) of the present application allows the nutrient solution to naturally come into contact with the tip of the root during the root growth process, thereby ensuring efficient supply of water and nutrients to the plant. Through this, optimal nutrient solution supply tailored to the plant's growth is possible, and the absorption efficiency of the root can be maximized.

[0154]

[0155] In alternative embodiments, the water collector (160) of FIG. 1 may be modified to have various shapes, or its arrangement structure or formation location may be modified to form various planar structures.

[0156] FIG. 13a is a perspective view of a water collector (160) according to alternative embodiments of the present application, and FIG. 13b is a plan view of the water collector (160) of FIG. 13a.

[0157] In the above-mentioned water collector (160), a drain pattern is formed on the drain surface (1631). The drain pattern includes a plurality of drain rings (16333) located at the intersections of virtual horizontal and vertical grid lines. That is, a set of drains (163333a) can be subset according to the number of drain rings (16333).

[0158] Each drainage ring (16333) is implemented in a shape in which a plurality of drains (16333a) are arranged along a virtual circumference. However, the arrangement shape of the plurality of drains (16333a) is not limited to a circular shape and can be arranged in various other shapes capable of forming the following combined water flow.

[0159] The diameter of the drainage ring (16333) can be set to a length such that the nutrient solution discharged from at least one of the plurality of drains (16333a) forming the drainage ring (16333) can form a single stream of water, i.e., a combined stream. The combined stream is formed by the combined action of physical properties such as surface tension, gravity, and flow alignment of water droplets of the nutrient solution discharged from the surrounding drains (16333a).

[0160] One drain hole (16333a) forming the drain ring (16333) has a diameter much smaller than the diameter of the drain ring (16333). The drain ring (16333) may have the same or similar size as the second drain hole (16332), but is not limited thereto.

[0161] The drainage ring (16333) can be arranged in the direction of growth of the plant roots. In FIG. 13, the drainage ring (16333) can be arranged in a vertical direction. Then, as described above with reference to FIG. 12, the drop of the nutrient solution can proceed according to the length of the plant roots.

[0162]

[0163] Figure 14 is a drawing showing the configuration of the lighting unit of Figure 1.

[0164] Referring to FIG. 14, the lighting unit (400) includes a lighting module (440) and a remote controller (450). In some embodiments, the lighting unit (400) may further include a sliding rail (410), a module support frame (420), and an actuator (430).

[0165] The sliding rail (410) is formed to extend in the forward and backward direction along the upper side of the support member (300). This facilitates the position adjustment of the lighting member (400) and allows the lighting module (440) to irradiate light at an optimal position according to the growth state of the plant (1). The sliding rail (410) serves as a precise guide to enable smooth and stable position adjustment of the lighting.

[0166] The module support frame (420) is formed to extend in the left-right width direction and is connected and installed so that it can slide in the front-back direction along a plurality of sliding rails (410). Through this, the lighting module (440) can adjust the distance from the plant cultivation unit (100) as needed and has the effect of adjusting the lighting intensity. In addition, the module support frame (420) supports a plurality of lighting modules (440) and maintains a constant spacing.

[0167] The actuator (430) is installed on the support member (300) and is connected to the module support frame (420). The actuator (430) moves the module support frame (420) toward the plant cultivation unit (100) or, conversely, away from the plant cultivation unit (100) through extension or contraction driving. By doing so, the appropriate lighting distance can be adjusted according to the growth stage of the plant (1), and lighting efficiency can be maximized.

[0168] A plurality of lighting modules (440) are spaced apart and installed along the lower side of the module support frame (420), facing each of the plurality of plant cultivation units (100). The lighting modules (440) irradiate light toward the plant cultivation units (100) so that the plants (1) can receive uniform light. Additionally, the lighting modules (440) may include LEDs or light sources of specific wavelengths and may be designed to adjust the light intensity and color temperature optimized for the growth of the plants (1).

[0169] The remote controller (450) is connected to the actuator (430) via a wireless or wired network and allows the position of the lighting unit (400) to be adjusted by driving the actuator (430) remotely. Through this, the user can remotely adjust the position and amount of light of the lighting and enable automated management. Additionally, the remote controller (450) may include a timer function and may have a function to automatically adjust the lighting module (440) according to the sunrise and sunset cycles.

[0170] A lighting unit (400) according to one embodiment of the present application having the configuration described above provides optimal lighting conditions according to the growth stage of a plant (1), thereby having the effect of improving the growth environment. In addition, through a sliding structure and an automatic adjustment function of an actuator (430), cultivation efficiency can be increased and convenience of maintenance can be improved.

[0172] Irrigation system

[0173] FIG. 15 is a schematic diagram of an irrigation system that supplies nutrient solution to a vertical hydroponic system according to another aspect of the present application.

[0174] Referring to FIG. 15, the vertical hydroponic system (10) is connected to a watering system (50). The watering system (50) supplies nutrient solution to the roots (2) of a plant installed in the vertical hydroponic system (10).

[0175] The above-described vertical hydroponic cultivation system (10) and watering system (50) are combined to form a system for hydroponic cultivation that supplies nutrient solution to plants arranged vertically. That is, the entire system includes one or more vertical hydroponic cultivation systems (10) and a watering system (500) that supplies nutrient solution to the one or more vertical hydroponic cultivation systems (10).

[0176] Here, the plurality of plant cultivation units (100), nutrient solution collection units (200), support units (300), and lighting units (400) are identical to the components of FIG. 1, so their descriptions are omitted to avoid duplication of description. Additionally, for clarity of explanation, the watering system (50) is described in more detail in embodiments in which the watering system (50) is connected to a single vertical hydroponic cultivation system (10).

[0177] The irrigation system (50) is installed in the support section (300) and performs the role of supplying nutrient solution to a plurality of plant cultivation sections (100).

[0178] In various embodiments of the present application, the irrigation system (50) may include a nutrient solution storage tank (501), a first piping line (510), a second piping line (530), a first pump (511), and a valve module (520).

[0179] The nutrient solution storage tank (501) stores the nutrient solution and functions as the starting point and recovery point of the first piping line (510). Additionally, the nutrient solution storage tank (501) functions as the recovery point of the second piping line (510).

[0180] The nutrient solution can be water, nutrients that plants absorb, or any combination thereof.

[0181] The first pump (511) connects the nutrient solution storage tank (501) and the first piping line (510). The first pump (511) provides hydraulic pressure to move the nutrient solution contained in the nutrient solution storage tank (501) along the first piping line (510). The first pump (511) can be set to maintain an appropriate flow rate and pressure according to the height of the vertical hydroponic system (10) and can have a function to adjust the flow rate as needed. This allows the nutrient solution to be supplied uniformly to each plant cultivation unit (100).

[0182] The first piping line (510) serves to transfer nutrient solution from the nutrient solution storage tank (501) to the plant cultivation unit (100). The first piping line (510) is installed to fit a vertical structure and is designed to enable uniform supply of nutrient solution to each plant cultivation unit (100). Additionally, it may include a structure that maintains a constant flow rate inside the piping so that an appropriate amount of nutrient solution can be supplied according to the growth stage of the plant (1).

[0183] A vertical hydroponic cultivation device (10) can be installed in a parallel arrangement along the extension direction of the first piping line (510).

[0184] The first pipe line (510) may be implemented as a pipe with an outer diameter of 60.5 mm, referred to as the 50a standard, but is not limited thereto. Additionally, the length of the first pipe line (510) may be extended to a length of 50 m to 100 m, but is not limited thereto.

[0185] According to embodiments, the nutrient solution storage tank (501) may be connected to a plurality of the first piping lines (510). Then, the nutrient solution may be discharged from the nutrient solution storage tank (501) through different paths at the same time.

[0186] In various embodiments of the present application, the first piping line (510) may be branched into a plurality of sub-lines (510a, 510b, ..., 510n). One or more vertical hydroponic devices (10) may be arranged in each sub-line (510a, 510b, ..., 510n). In one example, the first piping line (510) may be branched into five sub-lines (510a, 510b, ..., 510n), and 20 vertical hydroponic devices (10) may be arranged in each sub-line.

[0187] Hereinafter, for clarity of explanation, the irrigation system (50) of the present disclosure is described in more detail with embodiments using a single first piping line (510).

[0188] One end of the first pipe line (510) is connected to a nutrient solution storage tank (501), and the other end of the first pipe line (510) is connected to a nutrient solution storage tank (501). One end of the first pipe line (510) is an output terminal where the nutrient solution from the nutrient solution storage tank (501) is output, and the other end of the first pipe line (510) is an input terminal where the nutrient solution from the nutrient solution storage tank (501) is recovered. The portion of the first pipe line (510) between the one end and the other end of the first pipe line (510) is located around the vertical hydroponic cultivation device (10). A portion of the nutrient solution output from one end of the first pipe line (510) is supplied to a vertical hydroponic cultivation device (10), and the remainder of the nutrient solution output from one end of the first pipe line (510) continues along the first pipe line (510) and is recovered back into the nutrient solution storage tank (501) through the other end of the first pipe line (510).

[0189] The valve module (520) controls the amount of nutrient solution while branching the nutrient solution flowing along the first piping line (510) and supplying it to each of the multiple plant cultivation units (100).

[0190] The valve module (520) can be designed to be opened and closed independently for each individual plant cultivation unit (100). This allows the amount of nutrient solution supplied to be adjusted according to the growth condition of a specific plant (1). Additionally, in some embodiments, it may be further configured to include an automatic opening and closing valve function so that the nutrient solution can be supplied automatically according to the needs of the plant (1) via a sensor.

[0191] FIG. 16 is a detailed schematic diagram of the components of a valve module (520) according to various embodiments of the present application.

[0192] Referring to FIG. 16, the valve module (520) may include a valve (521) and a plurality of tubes (525). Additionally, in some embodiments, the valve module (520) may further include one or more second joint pipes (522) and / or one or more tube clamps (524) for fixing at least some of the plurality of tubes (525).

[0193] The valve (521) may be configured to control the flow area of ​​the nutrient solution branched from the first piping line (510). The valve module (520) can supply the nutrient solution to the vertical hydroponic cultivation device (10) when the valve (521) is open, and can block the supply of the nutrient solution to the vertical hydroponic cultivation device (10) when the valve (521) is closed. Additionally, the valve module (520) can control the supply speed and supply amount of the nutrient solution according to the degree of opening of the valve (521).

[0194] In some of the above embodiments, the valve (521) may have one input terminal and two output terminals. Two second joint pipes (521) may be connected to the left and / or right side of the valve (520), so that water input into the valve (520) may proceed to the left and / or right side.

[0195] The tube (525) supplies the nutrient solution that has passed through the valve (521) to the cartridge assembly (100). As shown in FIG. 3c, the output end of the tube (525) can be connected to the cartridge assembly (100) where plants are placed in the vertical hydroponic device (10). Through the tube (525), the nutrient solution can be supplied directly into the interior of the cartridge assembly (100).

[0196] The connection of the tube (525) is implemented so that the nutrient solution does not leak out in the middle between the valve (521) and the uppermost unit space, which is defined by the water barrier and the water collector located at the uppermost part of the cartridge assembly (100). The output end of the tube (525) is located on the uppermost unit space.

[0197] For example, the tube (525) may be connected to the cartridge assembly (100) in such a way that one end of the tube (525) is connected to the valve (521) and the other end of the tube (525) is inserted into the uppermost unit space of the cartridge assembly (100) and fixed at a point above the uppermost collector, but is not limited thereto.

[0198]

[0199] Additionally, in some embodiments, the second joint pipe (521) may have an L-shape.

[0200] The input end of the valve (521) is connected to the first piping line (510) through the first joint pipe (512). One or more first joint pipes (512) may be installed between one end and the other end of the first piping line (510). The first joint pipe (512) provides a branching point where the nutrient solution branches from the first piping line (510) toward the valve module (520). By means of the valve module (520) connected to the first joint pipe (512), a portion of the nutrient solution output from one end of the first piping line (510) is branched and supplied to the vertical hydroponic cultivation device (10).

[0201] The output end of the valve (521) is connected to a tube (525) through a second joint pipe (522). Each output end of the valve (521) may be connected to one or more tubes (525). In one example, individual output ends of the valve (521) may be connected to four tubes (525), but the number of connected tubes (525) is not limited thereto.

[0202] A tube clamp (524) can be installed when multiple tubes (525) are connected to the same output terminal. The tube clamp (524) connects the tube (525) and the output terminal of the valve (521) so that the gap between the multiple tubes (525) connected to the same output terminal does not widen and is fixedly coupled to the valve (521).

[0203] In various embodiments of the present application, the valve module (520) may be located at a position higher than the first piping line (510). The irrigation system (50) is configured so that the nutrient solution branched from the first piping line (510) rises upward and then descends through the valve module (520) to be supplied to the vertical hydroponic cultivation device (10).

[0204] As a result, regardless of whether the valve module (520) is open or closed, that is, even if the valve module (520) is open or closed, the supply of nutrient solution through the valve module (520) can be supplied collectively or blocked depending on the on or off of the pumping operation of the first pump (511). If the first piping line (510) and the valve module (520) are located at the same height or at a lower height, as shown in FIG. 1, and the first valve line (510) and the nozzle are located at the same height or at a lower height, then when the pumping operation of the first pump (511) is turned off while the valve module (520) is open, additional nutrient solution can be supplied through the valve module (520) to the vertical hydroponic cultivation device (10) even after the off time of the first pump (511) has elapsed. This is because water continues to flow out until all the water remaining in the pipe falls down, even after the pumping operation of the first pump (511) has ended. As a result, problems of excessive humidity and scale have occurred.

[0205] As such, the discrepancy between the on / off operation of the first pump (511) and the supply / stop of nutrient solution hinders precise control of the growth environment of plants within the vertical hydroponic system (10). Even if the off time of the first pump (511) has elapsed, if additional nutrient solution is supplied to the vertical hydroponic system (10) through the valve module (520), the plants may become overwatered, which may lead to reduced growth.

[0206] On the other hand, as illustrated in FIG. 15, if the valve module (520) is located at the top of the first piping line (510), the nutrient solution is no longer supplied to the vertical hydroponic cultivation device (10) through the valve module (520) from the time the first pump (511) is off. As a result, even if there are many valve modules (520), the supply of nutrient solution to the vertical hydroponic cultivation device (10) through the first piping line (510) can be controlled more conveniently and accurately in batches by controlling only one first pump (511).

[0207] The nutrient solution flowing through the first piping line (510) is supplied to the vertical hydroponic cultivation device (10) through the valve (521) and tube (525).

[0208] In this way, since the nutrient solution is supplied to the vertical hydroponic cultivation device (10) using the tube (525), no water is wasted outside the cartridge assembly (100) within the vertical hydroponic cultivation device (10). Additionally, because the tube (525) is used and the supply pressure of the nutrient solution through the valve (521) is uniform, an accurate amount of nutrient solution can be supplied to each cartridge, ultimately enabling more precise growth control.

[0209] As shown in FIG. 16, which illustrates the flow sequence of the nutrient solution, the nutrient solution flows rapidly first in the first piping line (510, number 1 in FIG. 16). Pressure applied by the pump (511) is transmitted to the rapidly flowing nutrient solution. As described above, even though the length of the first piping line (510) is long, pressure is maintained throughout the first piping line (510) due to the horizontal head, so that the nutrient solution rises from any valve module (520) to position 2, branches off at position 3, and at position 4, the nutrient solution is irrigated to the vertical hydroponic system (10) below by gravity.

[0210] The gate valve (513) is a valve installed at the recovery end of the first piping line (510) to control the flow rate of the nutrient solution recovered to the nutrient solution storage tank (501) through the first piping line (510). The gate valve (513) may be installed between the last valve module (520) and the storage tank (501).

[0211] The gate valve (513) prevents the phenomenon in which the nutrient solution is not relatively discharged from a specific valve module (520) even when the number of valve modules (520) exceeds a certain level and is too large.

[0212] Specifically, if there is no gate valve (513), and the number of valve modules (520) exceeds a certain level and becomes too large, causing the pressure inside the pipe to drop to 0.5 kPa, the output of the nutrient solution from one or more specific valve modules (520) may be reduced or not output. However, if a gate valve (513) is installed at the end of the first piping line (510) through which the nutrient solution loops back, thereby relatively narrowing the flow area passing through the valve (513), the pressure inside the pipe increases relatively. Consequently, even if the number of valve modules (520) exceeds a certain level and becomes too large, the output of the nutrient solution is uniformly performed from all piping modules (520).

[0213] The specifications of the gate valve (513) depend on the first piping line (510). In some embodiments, if the first piping line (510) is a piping of 50a specification, the gate valve (513) may be a valve for 50a specification.

[0214] The above irrigation system (50) has a double loop path structure in which the nutrient solution is recovered through a first loop path and a second loop path.

[0215] Among the nutrient solution flowing from the nutrient solution storage tank (501) in the above irrigation system (1) along the first piping line (510), i) the residual nutrient solution that is not absorbed by the cartridge assembly (100) among the portion of the nutrient solution branched from the first piping line (510) moves along the path of the first joint pipe (512), valve (520), second joint pipe (521), tube (525), vertical hydroponic device (10), discharge hole (130b) of the vertical hydroponic device (10), second piping line (530), and nutrient solution storage tank (501) as a first loop path, and ii) the remaining nutrient solution that is not branched from the first piping line (510) continues along the first piping line (510) and moves back to the nutrient solution storage tank (501). Some or all of the nutrient solution proceeding along the first loop path is used for plant growth within the vertical hydroponic device (10).

[0216] The above irrigation system (50) may be configured to form a loop-type nutrient path in which at least a portion of the nutrient solution, excluding the nutrient solution absorbed by the cartridge assembly (100) from the nutrient solution output from the nutrient solution storage tank (501), is recovered back to the nutrient solution storage tank (501). To this end, the first piping line (510) and the second piping line (530) may be configured to form the loop-type nutrient solution path. The nutrient solution originating from the nutrient solution storage tank (501) may proceed along the first piping line (510) to be recovered back to the nutrient solution storage tank (501), or it may proceed sequentially along the first piping line (510) and the second piping line (520) to be recovered back to the nutrient solution storage tank (501).

[0217] The second piping line (530) is connected to the nutrient solution collection unit (200) and serves to transfer the residual nutrient solution remaining after absorption in the plant cultivation unit (100) from the nutrient solution collection unit (200) back to the nutrient solution storage tank (501). The second piping line (530) establishes a circulation system for the reuse of the nutrient solution, thereby having the effect of minimizing the loss of the nutrient solution in hydroponic cultivation. Additionally, the second piping line (530) may be maintained to include a filter or purification device (not shown in the drawing for convenience of explanation) to remove impurities in the recovered nutrient solution and enable reuse.

[0218] FIG. 17 illustrates a connection structure between a nutrient solution storage tank (501) and a first piping line (510), and a connection structure between a nutrient solution storage tank (501) and a second piping line (530), according to various embodiments of the present application.

[0219] FIG. 17a illustrates the connection structure of the first piping line (510) and the second piping line (530) inside the nutrient solution storage tank (501), and FIG. 17b illustrates the connection structure of the first piping line (510) outside the nutrient solution storage tank (501).

[0220] Referring to FIG. 17, one end (510a) of the first piping line (510) through which the nutrient solution from the nutrient solution storage tank (501) is output is located relatively lower than the other end (510b) of the first piping line (510) and the other end (530b) of the second piping line in the nutrient solution storage tank (501). On the other hand, the other end (510b) of the first piping line (510), through which some of the nutrient solution that has continued along the first piping line (510) without branching off is recovered into the nutrient solution storage tank (501), is positioned so as to be exposed above the surface of the nutrient solution contained within the nutrient solution storage tank (501), and / or the other end (530b) of the second piping line (530), through which residual nutrient solution output from the vertical hydroponic device (10) is recovered, can be positioned so as to be exposed above the surface of the nutrient solution contained within the nutrient solution storage tank (501). This is to minimize damage to the piping line.

[0221] When the above-mentioned nutrient solution storage tank (501) receives a portion of the maximum capacity it can accommodate, the bottom of the nutrient solution storage tank (501) is filled with nutrient solution, and an empty space is formed at the top of the nutrient solution storage tank (501). As the nutrient solution flows through the first pipe line (510) and the second pipe line (530), the initial residual air within the first pipe line (510) and the second pipe line (530) is also pushed out. Since the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line are located in the empty space formed above the surface of the nutrient solution contained within the nutrient solution storage tank (501), the flow of the initial residual air is removed from the first pipe line (510) and the second pipe line (530) without any resistance or collision.

[0222] While the nutrient solution supply operation continues after the initial residual air is removed, the nutrient solution is supplied from the outside into the nutrient solution storage tank (501), causing the surface of the nutrient solution to gradually rise so that the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line are not exposed to the air layer and can be submerged below the surface of the nutrient solution. However, since the residual air in the pipe has already been removed, there is no problem in preventing damage to the pipe.

[0223] In addition, since the other end (510b) of the first piping line (510) and the other end (530b) of the second piping line are located in the empty space formed above the surface of the nutrient solution contained in the nutrient solution storage tank (501), the recovered nutrient solution is recovered by naturally falling through the air layer to the surface of the nutrient solution contained in the nutrient solution storage tank (501).

[0224] One end of the first pipe line (510) is connected to a nutrient solution storage tank (501), and the other end of the first pipe line (510) is connected to a nutrient solution storage tank (501). One end of the first pipe line (510) is an output terminal where the nutrient solution from the nutrient solution storage tank (501) is output, and the other end of the first pipe line (510) is an input terminal where the nutrient solution from the nutrient solution storage tank (501) is recovered. The portion of the first pipe line (510) between the one end and the other end of the first pipe line (510) is located around the vertical hydroponic cultivation device (10). A portion of the nutrient solution output from one end of the first pipe line (510) is supplied to a vertical hydroponic cultivation device (10), and the remainder of the nutrient solution output from one end of the first pipe line (510) continues along the first pipe line (510) and is recovered back into the nutrient solution storage tank (501) through the other end of the first pipe line (510).

[0225] In this way, the above-mentioned irrigation system (50) can recover the remaining nutrient solution from the nutrient solution output from the nutrient solution storage tank (501), excluding the amount used in the vertical hydroponic cultivation device (10), thereby maximizing resource recycling.

[0226] Additionally, in some embodiments, the hydroponic system (1) can detect when the nutrient solution in the storage tank (501) exceeds a critical height corresponding to the maximum capacity of the storage tank (501), which is defined by the height of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line, and control the flow rate of the nutrient solution flowing into the storage tank (501). Additionally, it may be further configured to detect this fact and output a notification to the system operator regarding the nutrient solution storage status.

[0227] To this end, the hydroponic system (1) may be configured to detect the height of the nutrient solution contained in the storage tank (501), such as a moisture sensor and / or a camera, and to calculate the real-time height of the nutrient solution contained in the storage tank (501) by analyzing the monitoring results of the detection means, and to compare the calculated real-time height with a preset threshold height, and to reduce the flow rate of the inflow and / or output a notification to the operator regarding the nutrient solution storage status if the real-time height exceeds the threshold height.

[0228] In some embodiments, the critical height may be the height of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line, or may be set to a height lower than a predetermined tolerance to avoid obstructing the flow of residual air in the pipe based on the height of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line.

[0229]

[0230] In various embodiments of the present application, the other end (510b) of the first piping line (510) and the other end (530b) of the second piping line (530) may be installed so as to fall at an appropriate angle within a certain orientation range with respect to the internal nutrient solution surface of the nutrient solution storage tank (501).

[0231] As illustrated in FIG. 17a, the other end (510b) of the first piping line (510) and the other end (530b) of the second piping line (530) are not directed toward the internal nutrient surface of the nutrient storage tank (501), so that the recovered nutrient does not fall vertically relative to the internal nutrient surface of the nutrient storage tank (501). The other end (510b) of the first piping line (510) and the other end (530b) of the second piping line (530) can be installed at a specific angle such that a vortex can be formed on the internal nutrient surface of the nutrient storage tank (501) without falling vertically relative to the internal nutrient surface of the nutrient storage tank (501). The installation angle of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530), having a specific value, determines the angle and direction in which the nutrient solution recovered from the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530) is incident on the surface of the nutrient solution inside the nutrient solution storage tank (501).

[0232] When the nutrient solution is discharged at an appropriate angle from the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530), a vortex is formed as the nutrient solution strikes the surface. In some embodiments, the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530) may be installed so that the discharged nutrient solution comes into contact with the wall of the nutrient solution storage tank (501). The installation angle of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530) may be expressed in the form of a three-dimensional vector having the direction in which the nutrient solution is discharged from the other end (510b, 530b).

[0233] In some embodiments, when the nutrient solution storage tank (501) has a two-dimensional circular plane, the three-dimensional installation angle of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530) can be set such that the result of projecting the three-dimensional installation angle of the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530) onto a two-dimensional plane parallel to the circular plane of the nutrient solution storage tank (501), where the other end (510b) of the first pipe line (510) and the other end (530b) of the second pipe line (530) are located, coincides with the tangential direction of the circle of the nutrient solution storage tank (501). When the nutrient solution is recovered and dropped in contact with the side of the nutrient solution storage tank (501) in alignment with the tangential direction, a vortex with stronger kinetic energy can be formed on the surface of the internal nutrient solution compared to when it is dropped at an angle other than that.

[0234] As shown in Fig. 17, when the water supply pipe that enters from the outside through the loop back is sprayed and recovered from the inside, natural stirring occurs inside the storage tank (501) and has the effect of increasing dissolved oxygen. Ultimately, stirring and an increase in dissolved oxygen can be achieved using only potential energy and kinetic energy without supplying separate electrical energy.

[0235] The first pump (511) may be a hydraulic pump that causes the flow rate of the nutrient solution output at the output end to be stronger than the flow rate of the nutrient solution input at the input end. The output pressure of the first pump (511) may be set to a value such that the variance between the pressure distributions of the nutrient solution output from a plurality of valve modules (520) connected to the first piping line (510) is less than or equal to a critical variance. In some embodiments, the output pressure of the first pump (511) may be set so that the pressures of the nutrient solution output from a plurality of valve modules (520) connected to the first piping line (510) are uniform to each other. To this end, the first pump (511) may control the output pressure so that the nutrient solution is output very strongly. In various embodiments of the present application, the output pressure of the first pump (511) may be set to a pressure greater than that at which the first pipe line (510) can be damaged when the other end (510b) of the first pipe line (510) is blocked and the nutrient solution is injected into the first pipe line (510) at the corresponding output pressure.

[0236] In a system where the hydroponic system (10) and the watering system (50) are simply connected without special measures, if the first pump (511) is driven with a high output pressure of approximately 5 kPa, there is a problem in that the first piping line (510) is damaged due to water hammering. On the other hand, in the entire system of FIG. 15, the first piping line (510) is not damaged even when the first pump (511) is driven with the same output pressure.

[0237] In this way, even when the first pump (511) is driven with a high output pressure sufficient to cause water hammering under specific piping conditions, the other end (510b) of the first piping line (510) in the watering system (50) is not blocked and is located in an air layer, so the air remaining in the first piping line (510) is discharged and ultimately, water hammering does not occur.

[0238] Additionally, in some embodiments, the output pressure of the first pump (511) may be a pressure that causes the nutrient solution traveling along the first piping line (510) to flow at a rate such that it is not entirely discharged through the valve module (520) connected to the first piping line (510). That is, some of the nutrient solution always flows through the first piping line (510).

[0239] In various embodiments of the present application, the output pressure of the first pump (511) may be set to 5 kPa to 10 kPa or higher. When the first pump (511) is driven with such a value, the piping is not damaged, and the pressure of the nutrient solution output from the valve module (520), that is, the supply pressure of the nutrient solution to each of the plurality of cartridge assemblies (100) in the vertical hydroponic device (10), may be uniform. For example, if the relative level of the supply pressure of the nutrient solution at the supply nozzle closest to the nutrient solution storage tank is 10, the relative level of the supply pressure of the nutrient solution at each of the supply nozzles that are increasingly farther away from the nutrient solution storage tank may be 10, 10, 10, ..., 10, or 10, 10, 10, 9, ..., 8.

[0240] The maximum value of the output pressure of the first pump (511) can be determined by the cross-sectional area of ​​the first piping line (510) and the physical properties of the first piping line (510).

[0241] Even when a relatively strong hydraulic pressure is applied in this way, because the other end (510b) of the first pipe line (510) is open, the final pressure inside the pipe (outside the initial stage of the watering operation) is maintained at a constant level of 1 to 1.5 kPa. This pressure inside the pipe is maintained almost uniformly along the entire length of the first pipe line (510). This is because only the horizontal head is applied for the length of the pipe remaining from a specific point to the outlet.

[0242] In this way, the above-mentioned irrigation system (50) can recover the remaining nutrient solution from the nutrient solution output from the nutrient solution storage tank (501), excluding the amount used in the vertical hydroponic cultivation device (10), thereby maximizing resource recycling.

[0243]

[0244] An irrigation system (50) according to one embodiment of the present invention having the configuration described above has the effect of maximizing the operational efficiency of a vertical hydroponic cultivation system (10) by safely controlling the supply and recovery of nutrient solution. In addition, it performs the function of promoting uniform growth of plants (1) by minimizing resource waste and maintaining a constant cultivation environment through a nutrient solution circulation system.
