[0063] Figure 1 It is a perspective view of the plant cultivation device according to an embodiment of the present invention. Additionally, Figure 2 It is a perspective view of the upper main body and the lighting device, which are components of the plant cultivation device.

[0064] As shown in the figure, the plant cultivation device 1 according to an embodiment of the present invention may include a main body 2 that forms a cultivation space 100 for cultivating plants ( Figure 9 P in). The main body 100 may include a lower main body 10 and an upper main body 20. The cultivation space 100 may be defined by the space between the lower main body 10 and the upper main body 20. That is, the cultivated plant P can grow inside the cultivation space 100 between the lower main body 10 and the upper main body 20.

[0065] On the other hand, the cultivation space 100 may include a first area for the plant P to grow (Figure 9 A1) in [the first area] and a second area above the first area A1 ( Figure 9 A2) in [the second area]. The plant P grows in the first area A1, and the height of the first area A1 can be changed according to the growth of the plant P. The first area A1 can be referred to as a growth area or a variable area. In addition, the lighting device 30 that illuminates the cultivation space 100 can be lifted and lowered in the second area A2. The second area A2 can be referred to as a lifting area. The second area A2 can be formed to be inversely proportional to the height change of the first area A1.

[0066] The lower body 10 can extend longitudinally in the left - right direction, and the left and right ends of the lower body 10 can be formed with arcs. The lower body 10 can form the bottom surface of the plant cultivation device 1, and the plant P is disposed on the lower body 10. Specifically, a tray receiving portion 101 recessed downward can be formed on the top surface of the lower body 10. A plurality of the tray receiving portions 101 can be formed.

[0067] In addition, trays 61, 63 for cultivating the plant P can be provided in the tray receiving portion 101. The trays 61, 63 can be configured in different types according to the form of the cultivated plant P and can be configured to be installable in the tray receiving portion 101. As an example, the trays 61, 63 can include a cultivation pot tray 63 and a container tray 61. A cultivation pod (pod) 64 including seeds and a culture medium is placed on the cultivation pot tray 63, and a container 62 for hydroponics is placed on the container tray 61.

[0068] The cultivation pot tray 63 can be formed in a size corresponding to the tray receiving portion 101, and a cultivation pot receiving portion 631 with an open top surface can be formed. In addition, the cultivation pot 64 can be disposed inside the cultivation pot receiving portion 631, and water supplied to the cultivation pot 64 can be filled.

[0069] The container tray 61 can be formed in a shape corresponding to the tray receiving portion 101, and the top surface of the container tray 61 can have a height corresponding to the open top surface of the tray receiving portion 101. In addition, a container opening 611 for inserting the container 62 can be formed in the container tray 61. The container opening 611 can have a size corresponding to the cross - sectional area of the container 62, and a plurality of the container openings 611 can be formed. Therefore, the user can insert and install the container 62 into the container opening 611. In a state where the container 62 is installed, the height of the container 62 can be formed to be higher than the height of the cultivation pot tray 63.

[0070] The user can selectively install the cultivation pot tray 63 or the container tray 61 in the tray accommodating part 101 according to the type or form of the plant.

[0071] The upper main body 20 can be arranged above the lower main body 10 to form the top surface of the plant cultivation device 1. Additionally, the size of the bottom surface of the upper main body 20 can be formed to correspond to the size of the top surface of the lower main body 10.

[0072] The lifting assembly 200 described later can be arranged on the upper main body 20. Additionally, a lighting device 30 for irradiating light to the plant P can be arranged below the upper main body 20.

[0073] The lighting device 30 can be connected to the upper main body 20 by a wire 261. The wire 261 can enter and exit the inside of the upper main body 20. Therefore, as the wire 261 is introduced and pulled out, the lighting device 30 can move up and down, so that the height inside the plant cultivation device 1 can be adjusted. As an example, the lighting device 30 can contact the bottom surface of the upper main body 20 at the highest position. Additionally, the lighting device 30 can be located at the upper end of the container 62 or the upper end of the cultivated plant P at the lowest position. That is, the lighting device 30 can move up and down in the second area A2 in the cultivation space 100.

[0074] Additionally, the top surface of the lighting device 30 can be formed to have the same size and shape as the bottom surface of the upper main body 20. Therefore, when the lighting device 30 is installed in contact with the upper main body 20, it can be integrated with the upper main body 20.

[0075] Additionally, the wire 261 can be respectively connected to the left and right sides of the top surface of the lighting device 30. Additionally, a bunch of the wires 261 can be respectively arranged at intervals on the left and right sides of the lighting device 30, so that the lighting device 30 can move up and down in a stable state without tilting.

[0076] In addition to being connected to the lighting device 30 to lift the lighting device 30, the wire 261 can also supply power to the lighting device 30. That is, at least a part of the wire 261 can be configured as an electric wire to supply power to the lighting device 30.

[0077] Additionally, the lighting device 30 can be arranged in parallel with the bottom surface of the upper main body 20 and the top surface of the lower main body 10. Therefore, during the lifting process of the lighting device 30, the lighting device 30 also maintains a state parallel to the top surface of the lower main body 10, so that light can be evenly irradiated to the plant P arranged on the lower main body 10.

[0078] Hereinafter, the specific structures of the upper main body 20 and the lighting device 30 will be described in detail.

[0079] The plant cultivation device 1 may further include a frame 40. The frame 40 may be disposed between the upper main body 20 and the lower main body 10. The frame 40 may connect the upper main body 20 and the lower main body 10. A pair of the frames 40 may be arranged on the left and right sides. Additionally, the frame 40 may connect the rear end of the top surface of the lower main body 10 and the rear end of the bottom surface of the upper main body 20. Additionally, the frame 40 may be located at the left and right side ends of the back surfaces of the lower main body 10 and the upper main body 20. Furthermore, the frame 40 may be fixed to a wall surface ( Figure 9 W in), and the plant cultivation device 1 may be installed in a form of being hung on the wall surface W.

[0080] A hollow 401 may be formed inside the frame 40. Thus, the inside of the lower main body 10 and the inside of the upper main body 20 may communicate with each other through the frame 40. Additionally, a power cord 43 may be arranged on at least one side of the frames 40 on the left and right sides. That is, the power cord 43 may be led from the lower main body 10 through the frame 40 to the upper main body 20. Additionally, the power cord 43 may be connected to electrical components provided inside the upper main body 20 for power supply. As an example, the power cord 43 may be connected to the lighting device 30. Additionally, the power cord 43 may be connected to the lifting assembly 200. Additionally, the power cord 43 may be connected to the operation unit 211.

[0081] The plant cultivation device 1 may include a cover 50. The cover 50 may shield the exposed spaces of the lower main body 10 and the upper main body 20 and provide a growth space for the plant P.

[0082] The cover 50 may include a front cover 51 forming the front surface of the plant cultivation device 1, a rear cover 52 forming the rear surface of the plant cultivation device 1, and side covers 53, 54 forming the left and right side surfaces of the plant cultivation device 1.

[0083] The front cover 51 may be formed along the front surfaces of the lower main body 10 and the upper main body 20. Additionally, the front cover 51 may be fixed by connecting between the front surface of the lower main body 10 and the front surface of the upper main body 20.

[0084] The rear cover 52 may be formed along the rear surfaces of the lower main body 10 and the upper main body 20. Additionally, the rear cover 52 may be fixed by connecting between the rear surface of the lower main body 10 and the rear surface of the upper main body 20.

[0085] The side covers 53 and 54 may be formed along the two side surfaces of the lower body 10 and the upper body 20. The two side surfaces of the lower body 10 and the upper body 20 may be formed with an arc, so the side covers 53 and 54 may also be formed with an arc in a corresponding curved shape. The side covers 53 and 54 may be connected between the side surfaces of the lower body 10 and the upper body 20.

[0086] On the other hand, the front cover 51, the rear cover 52 and the side covers 53 and 54 may be formed of a transparent material through which the inside can be seen. For example, the cover 50 may be formed of a transparent plastic, acrylic resin or glass material.

[0087] In addition, at least a portion of the cover 50 is provided in a detachable manner, so that the cultivated plant P or the tray 61, 63 can be placed in or taken out of the plant cultivation device 1 by attaching and detaching the cover 50. As an example, the side covers 53, 54 can be provided in a detachable manner. If the side covers 53, 54 are separated, the plant P arranged on the lower body 10 can be accessed, and the cultivation pot tray 63 or the container tray 61 can be attached and detached, or water can be additionally supplied to the container 62 or the cultivation pot 64.

[0088] Hereinafter, with reference to the accompanying drawings, the structures of the upper body 20 and the lifting assembly 200 will be described in detail.

[0089] Figure 3 is an exploded perspective view of the upper body. Figure 4 yes Figure 3 Enlarged view of part A.

[0090] As shown in the figure, the upper body 20 is formed to have a size corresponding to the lower body 10 and can be located vertically above the lower body 10. In addition, the upper body 20 can be long and extend in the left and right directions, and the left and right side ends of the upper body 20 can be formed with arcs.

[0091] The upper body 20 may include a body top 21 forming an upper portion of the upper body 20 and a body base 22 combined with the body top 21 to form a lower portion of the upper body 20 .

[0092] The main body top 21 may form the top surface of the plant cultivation device 1. The main body top 21 may be exposed upward when the front cover 51, the rear cover 52, and the side covers 53 and 54 are installed, thereby forming the top surface appearance of the plant cultivation device 1.

[0093] In addition, an operation unit 211 for inputting a user operation may be formed on the upper main body 20. As an example, the operation unit 211 may be disposed inside the upper main body 20 to input an operation by a touch method, and an operation may be input by a touch operation on the top 21 of the main body. Of course, the operation unit 211 may also be exposed on the top 21 of the main body in the form of a button or a switch. In addition, the operation unit 211 may further include a display unit 211a for displaying the operation of the plant cultivation device 1.

[0094] A display device 29 may be disposed inside the upper main body 20 corresponding to the operation unit 211. The display device 29 may include a substrate 291 and a display module 292. In addition, a touch device 293 for sensing the operation of the operation unit 211 may also be disposed in the display module 292.

[0095] The main body base 22 may be open upward and may be combined with the top 21 of the main body to shield the top surface of the opening. In addition, the inside of the main body base 22 may be recessed downward to form a base accommodation portion 220 for disposing the lifting assembly 200.

[0096] Specifically, a base rib 221 extending upward may be formed on the main body base 22. The base rib 221 may extend along the main body base 22 and may be formed along the central portion of the main body base 22. In the base rib 221, a pair of ribs extending linearly may be spaced apart from each other, and both ends of the pair of ribs may be formed in an arc shape.

[0097] The base rib 221 may be formed in the base accommodation portion 220 for internally accommodating the lifting assembly 200. That is, the lifting assembly 200 may be disposed inside the space formed by the base rib 221. At this time, the base rib 221 may be used to guide the movement member 25 moving in the left and right side directions so as not to disengage.

[0098] In addition, a coupling member 262 for connecting the wire 261 to the movement member 25 may be disposed in the base accommodation portion 220. In addition, a roller 263 for guiding the bending and introduction and extraction of the wire 261 may be disposed in the base accommodation portion 220. In addition, a guiding module 24 for guiding the movement member 25 may be disposed in the base accommodation portion 220. The roller 263 and the coupling member 262 may be disposed at the left and right side ends of the base accommodation portion 220. In addition, the lifting assembly 200 and the guiding module 24 may be disposed between the roller 263 and the coupling member 262.

[0099] When the top 21 of the main body is combined, the top surface of the base accommodation portion 220 may be shielded by the top 21 of the main body, and the lifting assembly 200 may be restricted from disengaging.

[0100] On the other hand, the bottom surface of the main body base 22 may be formed into a planar shape parallel to the top surface of the lighting device 30. Additionally, the bottom surface of the main body base 22 and the top surface of the lighting device 30 may be formed into the same size as each other. Further, in a state where the lighting device 30 is in the highest position, the bottom surface of the main body base 22 may be in contact with the top surface of the lighting device 30.

[0101] Hereinafter, with reference to the drawings, the lifting assembly 200 will be described in detail.

[0102] Figure 5 It is a perspective view of the lifting assembly which is a component of the upper main body as viewed from below. Additionally, Figure 6 It is Figure 3 An enlarged view of part B.

[0103] As shown in the figure, the lifting assembly 200 may include a driving part 231 that provides rotational power, a pinion 233 that rotates using the driving part 231, and a moving member 25 that reciprocates by meshing with the pinion 233.

[0104] Specifically, the driving part 231 may be composed of a motor that rotates forward and backward. The driving part 231 may be driven according to the input of the operation part 211 of the user. The driving part 231 may be composed of a first driving part 231a and a second driving part that are respectively connected to a pair of first pinions 233a and second pinions 233b. Additionally, by making the operations of the first driving part 231 and the second driving part 231b consistent with each other, the wire 261 on both sides can be formed into the same length. Therefore, the lighting device 30 can be lifted and lowered stably without tilting.

[0105] The lifting assembly 200 may include the driving part 231, the pinion 233, and the moving member 25 that are respectively arranged on the left and right sides, and may be at symmetric positions on both sides with the center of the upper main body 20 as a reference. Additionally, the driving part 231, the pinion 233, and the moving member 25 arranged on both sides may have the same structure. That is, the pinion 233 may be composed of a first pinion 233a and a second pinion 233b, and the moving member 25 may be composed of a first moving member 25a and a second moving member 25b.

[0106] Therefore, the structure of one side of the driving part 231, the pinion 233, and the moving member 25 will be described.

[0107] A gear module 232 may be connected to the rotating shaft of the driving unit 231. The gear module 232 may also be composed of a first gear module 232a and a second gear module 232b. The gear module 232 may transmit the rotational force between the rotating shaft of the driving unit 231 and the rotating shaft 2332 of the pinion 233. Therefore, when the driving unit 231 operates, under the action of the gear module 232, the rotating shaft 2332 of the pinion 233 arranged in the direction intersecting the rotating shaft of the driving unit 231 can rotate. At this time, the rotating shaft 2332 of the pinion 233 may engage with the gear module 232 to transmit the rotational force.

[0108] In addition, a pinion 2331 may be formed on the periphery of the pinion 233. The pinion 2331 may be formed on the peripheral edge of the bottom surface and may form a step from the top surface of the pinion 233. In addition, the pinion 2331 may engage with the rack 251 of the moving member 25. In addition, the top surface of the pinion 233 may protrude more outward than the peripheral edge of the pinion 2331, restricting the upward movement of the moving member 25 so that the engagement between the moving member 25 and the pinion 233 is not released.

[0109] The moving member 25 may be formed to extend along the length direction of the upper main body 20 and may linearly reciprocate within the base accommodating portion 220. Specifically, a rack 251 may be formed on one surface of the moving member 25, and the rack 251 may be connected to the pinion 2331. At this time, the moving member 25 may be configured to pass through the pinions 233 on both sides. Therefore, the racks 251 formed on the pinions 233 on both sides may be all engaged with each pinion 2331. In addition, a pair of moving members 25 may be arranged in a direction facing each other with the pinion 233 as the center and may engage with all the pinions 233. Therefore, when a pair of the driving units 231 operate, a pair of the moving members 25 may operate simultaneously and may move the same distance in opposite directions. That is, a pair of the moving members 25 can ensure that the left and right sides of the lighting device 30 are lifted and lowered without tilting.

[0110] On the other hand, a slider mounting portion 252 may be formed at one end of the moving member 25, and a slider 242 may be provided on the bottom surface of the slider mounting portion 252. A plurality of the sliders 242 may be provided at a preset interval along the moving member 25.

[0111] In addition, a coupling member mounting portion 253 may be formed at the other end of the moving member 25. The coupling member 262 connected to the wire 261 may be mounted on the coupling member mounting portion 253. Therefore, the wire 261 may move together with the movement of the moving member 25, and the length of the wire 261 exposed to the outside of the upper main body 20 may be adjusted.

[0112] On the other hand, a guide module 24 may be provided below the moving member 25. The guide module 24 may be disposed inside the base accommodation portion 220.

[0113] The guide module 24 includes a guide rail 241 installed inside the base accommodation portion 220 and a slider 242 installed on the guide rail 241. As an example, the guide module 24 may be composed of an LM guide (Linear motion guide).

[0114] The guide rail 241 may extend along the movement path of the moving member 25, and at least a part of the section may be cut to avoid interference with the driving unit 231. In addition, a plurality of the sliders 242 may be configured to be movable along the guide rail 241 and contact the guide rail 241 by using balls or bearings, so as to smoothly slide. Therefore, the moving member 25 may move more smoothly by using the slider 242 moving along the guide rail 241.

[0115] The guide module 24 may be disposed at positions corresponding to the pair of moving members 25 respectively, and thus, the movement of each of the moving members 25 can be guided. The first guide module 24a and the second guide module 24b may be provided at positions corresponding to the first moving member 25 and the second moving member 25 respectively. That is, the pair of guide rails 241 may be spaced apart and disposed below each of the pair of moving members 25.

[0116] On the other hand, a coupling member 262 may be provided at the end of the moving member 25. The coupling member 262 extends in a direction crossing the extending direction of the moving member 25. In addition, the bottom surface of the coupling member 262 may be supported by the pair of guide rails 241. At this time, a slider 242 may also be provided on the bottom surface of the coupling member 262.

[0117] In addition, the ends of a pair of the wires 261 may be fixed to the coupling member 262. The wires 261 may be spaced apart by a predetermined interval and may move together with the coupling member 262 when the moving member 25 moves. In addition, a pair of wire holes 222 through which the wires 261 pass in and out may be formed inside the base accommodation portion 220. Therefore, the wires 261 may extend downward through the bottom surface of the upper body 20, that is, the body base 22.

[0118] On the other hand, a roller 263 may be rotatably installed on the body base 22. The roller 263 may support the wire 261 from the coupling member 262 toward the wire hole 222 in a bent state. The roller 263 may be located above the wire hole 222.

[0119] The roller 263 may be formed in a cylindrical shape and may be axially coupled to roller support platforms 265 installed on both sides of the base accommodation portion 220. In addition, a pair of wire grooves 2631 may be formed on the outer circumferential surface of the roller 263. The wire grooves 2631 may be formed along the outer circumferential surface of the roller 263 to accommodate the wire 261. In addition, the wire grooves 2631 may be formed to have an interval corresponding to the interval of the wire holes 222 so that the wire 261 can bend and move through the wire holes 222 while maintaining a predetermined interval.

[0120] That is, as the moving member 25 moves, the wire 261 may be bent and guided by the roller 263 to move. In addition, the wire 261 may move up and down while maintaining a set interval.

[0121] On the other hand, a roller cover 264 may be installed at the end of the base accommodation portion 220 where the roller 263 is installed. The roller cover 264 may cover a part of the top surface of the base accommodation portion 220 where the roller 263 is installed and may cover the roller 263. Therefore, the roller cover 264 can prevent the roller 263 and the wire 261 from being disassembled.

[0122] The coupling member 262 and the roller 263 may be disposed on both sides of the base accommodation portion 220, may be connected to the wires 261 on both sides of the upper body 20, and may guide the wires 261.

[0123] Hereinafter, the structure of the lighting device 30 will be described in detail.

[0124] Figure 7 is an exploded perspective view of the lighting device.

[0125] As shown in the figure, the lighting device 30 may include a light source 34 that emits light, a lamp housing 33 that houses the light source 34, and a lamp cover 35 that shields the light source 34.

[0126] As an example, the light source 34 may include a substrate 341 and LEDs (light-emitting diodes) 342. The substrate 341 may have a size corresponding to the interior of the lamp housing 33. In addition, a plurality of LEDs 342 may be arranged on the substrate 341 at a predetermined interval. At this time, at least a part of the LEDs 342 may also be RGB LEDs capable of irradiating light of various colors. In addition, the LEDs 342 may be arranged on the bottom surface of the substrate 341 to irradiate light downward. That is, the LEDs 342 may irradiate light toward the top surface of the lower body 10.

[0127] The lamp housing 33 may include a housing plate 31 forming the top surface of the lighting device 30 and a housing frame 32 forming the peripheral surface of the lighting device 30. The housing plate 31 may be formed in a plate shape and may be formed in a size and shape corresponding to the bottom surface of the upper body 20, that is, the bottom surface of the body base 22.

[0128] In addition, wire connection parts 311 connected to the wire 261 may be formed on both sides of the housing plate 31. The wire connection parts 311 may penetrate the housing plate 31, and the wire 261 may be led into the interior of the lighting device 30 through the wire connection parts 311 to supply power to the light source.

[0129] The wire connection parts 311 may be provided on the left and right sides of the housing plate 31, respectively. In addition, the wire connection parts 311 on the left and right sides may be spaced apart at the same interval in the front-rear direction. Therefore, the top surface of the lighting device 30 may be stably suspended by all four wires 261, and the height of the lighting device 30 may be determined according to the length of the wire 261 led out from the upper body 20.

[0130] The top surface and the bottom surface of the housing frame 32 may be open, the opening of the top surface of the housing frame 32 may be shielded by the housing plate 31, and the bottom surface of the housing frame 32 may be shielded by the lamp cover 35.

[0131] The housing frame 32 may be formed to gradually extend outward when extending from top to bottom in an inclined or arc shape. Therefore, the lamp cover 35 may be formed in a size larger than that of the housing plate 31 to irradiate a sufficient amount of light to the plant P.

[0132] The lamp cover 35 may be formed of a light-transmissive material and may shield the bottom surface of the opening of the lamp housing 33. The lamp cover 35 may have a structure capable of diffusing light or a structure added with a diffusing agent. Therefore, the lighting device 30 may emit light in the form of a surface light source and may irradiate light uniformly to the plant P. In addition, the lighting device 30 may also utilize surface emission to achieve the function of indirect lighting indoors.

[0133] Hereinafter, with reference to the drawings, the operation of the plant cultivation device 1 having the above-described structure will be described in detail.

[0134] Figure 8 It is a view showing the state of the lifting assembly when the height of the lighting device is in the highest state. In addition, Figure 9 It is from a side view Figure 8 a view showing the state of the plant cultivation device in the state shown.

[0135] As shown in the figure, when cultivating the plant P with a relatively high cultivation height in the plant cultivation device 1 or when a container 62 with a relatively high height is arranged in the lower main body 10, the lighting device 30 can be arranged as Figure 9 shown.

[0136] In this way, when using a container 62 with a relatively high height or when the plant P grows to a relatively high height, the first area A1 can be set higher than Figure 11 the case shown. In addition, as the vertical length of the first area A1 is elongated, the vertical length of the second area A2 is reduced in inverse proportion thereto. In addition, the lighting device 30 can be lifted and lowered within the second area A2 so that the plant P cannot touch it.

[0137] As an example, in a state where the lighting device 30 is arranged at the highest position, the top surface of the lighting device 30 can be in a state of contacting the bottom surface of the upper main body 20. In the state as described above, it can be regarded that the lighting device 30 and the upper main body 20 are integrally formed with each other.

[0138] In a state where the lighting device 30 is located at the highest position, the state of the lifting assembly 200 is such that the moving member 25 moves so that the coupling member 262 is located at the position farthest from the wire hole 222. The coupling member 262 can be located at the farthest position based on the left and right side ends of the upper main body 20. In addition, it can be located at the nearest position based on the pinion 233. In addition, the distance between the coupling members 262 on both sides can be in a minimum state.

[0139] At this time, the position of the coupling member 262 can cause all of the wire 261 to be introduced into the interior of the upper main body 20. Therefore, the wire 261 can be prevented from being exposed to the outside, and the lighting device 30 can be in a state of contacting the bottom surface of the upper main body 20. Therefore, sufficient space can be ensured below the lighting device 30, and a plant P or the container 62 with a relatively high height can be arranged.

[0140] In the state as described above, the lighting device 30 can adjust its height within the range of the second area A2 according to the growth degree of the plant P.

[0141] In addition, when the plant P with a lower height is arranged in the lower main body 10 or the cultivation pot 64 or the cultivation pot tray 63 is installed instead of the container 62 with a higher height, the height of the lighting device 30 can be reduced.

[0142] Specifically, the user can operate the operation unit 211 to actuate the drive unit 231. By the forward rotation operation of the drive unit 231, the pinion 233 rotates forward, and the moving member 25 engaged with the pinion 233 moves horizontally through the rotation of the pinion 233.

[0143] Through the movement of the moving member 25, the coupling member 262 also moves together. At this time, the coupling member 262 can move toward the side end of the upper main body 20. In addition, the coupling members 262 on both sides can move away from each other.

[0144] Through the movement of the moving member 25 and the coupling member 262, the wire 261 can move downward through the wire hole 222. The end of the wire 261 is coupled to the lighting device 30. Therefore, under the action of the self-weight of the lighting device 30, the wire 261 can be led out of the upper main body 20 in a taut state.

[0145] The moving members 25 arranged on both sides move at the same distance, and the leading-out distance of the wire 261 is also the same. Therefore, the lighting device 30 can descend without tilting.

[0146] The operation of the operation unit 211 can be configured until the lighting device 30 reaches the desired height. Through the operation of the operation unit 211, during the driving of the drive unit 231, the moving member 25 can continuously move toward the side end of the upper main body 20, and the wire 261 can be led out below the upper main body 20.

[0147] If the lighting device 30 reaches the desired height, the user completes the operation of the operation unit 211 and stops the action of the drive unit 231. If the drive unit 231 stops, the moving member 25 also stops moving, and the lighting device 30 can maintain the corresponding height.

[0148] Figure 10 It is a view showing the state of the lifting assembly when the height of the lighting device is in the lowest state. In addition, Figure 11 It is from a side view Figure 10 a view showing the state of the plant cultivation device in the state shown.

[0149] As shown in the figure, when cultivating the plant P with a relatively low cultivation height in the plant cultivation device 1 or arranging the cultivation pot 64 or the cultivation pot tray 63 with a relatively low height in the lower main body 10, the lighting device 30 can be arranged as Figure 11 shown.

[0150] Thus, when using the cultivation pot 64 or the cultivation pot tray 63 with a relatively low height or when the plant P grows to a relatively low height, the first region A1 can be set to be relatively lower compared with the Figure 9 shown situation. In addition, as the vertical length of the first region A1 shortens, the vertical length of the second region A2 increases inversely. In addition, the lighting device 30 can move up and down within the second region A2 without touching the plant P.

[0151] As an example, the lighting device 30 can move to the lowest height. The lowest height of the lighting device 30 can be set to a position higher than the upper ends of the cultivation pot 64, the cultivation pot tray 63 or the upper ends of the cultivated plants P.

[0152] Under the operation of the operation unit 211, when the lighting device 30 moves to the lowest height, the wire 261 can be in a state of extending with the maximum length, and the lighting device 30 can be located at the lowest position between the upper main body 20 and the lower main body 10.

[0153] When the lighting device 30 is in the state of being located at the lowest position, the state of the lifting assembly 200 is that the moving member 25 moves so that the coupling member 262 is located at the position closest to the wire hole 222. The coupling member 262 can be located at the nearest position based on the left and right side ends of the upper main body 20. In addition, it can be located at the farthest position based on the pinion 233. In addition, the distance between the two side coupling members 262 can be in the maximum state.

[0154] Therefore, the length of the wire 261 exposed to the outside can become the maximum, and the lighting device 30 can be in a state of being farthest from the upper main body 20 and closest to the lower main body 10. Therefore, the lighting device 30 can be close to the top surface of the lower main body, and can more effectively irradiate light in the state of arranging the plant P with a relatively low height or the cultivation pot 64 or the cultivation pot tray 63.

[0155] In the state as described above, the lighting device 30 can adjust its height within the range of the second region A2 according to the growth degree of the plant P.

[0156] In addition, when arranging the plant P with a relatively high height in the lower main body 10 or installing a container with a relatively high height, the height of the lighting device 30 can be increased.

[0157] Specifically, the user can operate the operation unit 211 to actuate the drive unit 231. Through the reverse rotation of the drive unit 231, the pinion gear 233 rotates in reverse, and through the rotation of the pinion gear 233, the moving member 25 engaged with the pinion gear 233 moves horizontally.

[0158] With the movement of the moving member 25, the coupling member 262 also moves together. At this time, the coupling member 262 can move in a direction away from the side end of the upper main body 20. In addition, the coupling members 262 on both sides can move towards each other.

[0159] Through the movement of the moving member 25 and the coupling member 262, the wire 261 can be introduced into the interior of the upper main body 20 through the wire hole 222. Therefore, the lighting device 30 can move upward. The operation of the operation unit 211 can be configured until the lighting device 30 reaches the desired height. The lighting device 30 can also move to a height in contact with the upper main body 20 as Figure 9 shown.

[0160] On the other hand, in addition to the above embodiments, the present invention can also be implemented as various other embodiments. Another embodiment of the present invention is characterized in that the user directly moves and operates the lifting assembly. In another embodiment of the present invention, the configuration other than a part of the lifting assembly is the same as that of the above embodiment, and the same reference numerals are used for the same configurations and shown, and the detailed description and illustration thereof are omitted.

[0161] Hereinafter, with reference to the drawings, another embodiment of the present invention will be described.

[0162] Figure 12 is a perspective view of the upper main body and the lighting device, which is a configuration of a plant cultivation device according to another embodiment of the present invention. In addition, Figure 13 is a view showing the state of the lifting assembly when the height of the lighting device is in the highest state. In addition, Figure 14 is a view showing the state of the lifting assembly when the height of the lighting device is in the lowest state. In addition, Figure 15 is a partial perspective view showing the operating state of the lifting assembly.

[0163] As shown in the figure, a plant cultivation device 1 according to another embodiment of the present invention may include a lower main body 10, an upper main body 20, and a lighting device 30. The upper main body 20 may include a main body top 21 forming the top surface and a main body base 22 accommodating the lifting assembly 200'.

[0164] In addition, a cutout portion 212 may be formed at the top 21 of the main body to expose an operation member 27 for operating the lifting assembly 200'. The operation member 27 may move along the cutout portion 212, and the lifting assembly 200' may be actuated by the movement operation of the operation member 27. As an example, the cutout portion 212 may extend longitudinally in the extending direction of the upper main body 20, that is, the left and right side directions. In addition, a part of the operation member 27 may protrude above the upper main body 20 through the cutout portion 212.

[0165] On the other hand, a base rib 221 may be formed on the main body base 22, and a base accommodation portion 220 for mounting the lifting assembly 200' and the guide module 24 may be formed through the base rib 221. In addition, a coupling member 262 and a roller 263 may be respectively provided on the left and right sides of the base accommodation portion 220 to allow the wire 261 to enter and exit the left and right sides of the upper main body 20.

[0166] The lifting assembly 200' may include a pinion 233 rotatably mounted on the upper main body 20, a moving member 25 that reciprocates by meshing with the pinion 233, and the operation member 27 provided on the moving member 25. The pinion 233 may be formed by a pair of a first pinion 233a and a second pinion 233b, and the moving member 25 may also be formed by a pair of a first moving member 25a and a second moving member 25b. In addition, the guide module 24 may also be formed by a pair of a first guide module 24a and a second guide module 24b.

[0167] The rotation shaft 2332 of the pinion 233 may be rotatably mounted on the main body base 22. In addition, a pinion 2331 formed along the circumference of the pinion 233 may be engaged with a rack 251 of the moving member 25. A pair of the pinions 233 may be provided at the center of the main body base 22 and may be arranged spaced apart from each other.

[0168] A pair of the moving members 25 may be arranged in directions opposite to each other with respect to the pinion 233. In addition, the moving members 25 may be engaged with all of the pair of pinions 233. Therefore, the pair of pinions 233 may rotate in the same direction, and as the pinions 233 rotate, the moving members 25 on the left and right sides may move in directions opposite to each other.

[0169] The moving member 25 can extend along the extending direction of the upper main body 20. Additionally, a rack 251 engaged with the pinion 2331 can be formed along the moving member 25. Additionally, a slider mounting portion 252 for mounting the slider 242 can be formed at one end of the moving member 25. Additionally, a plurality of the sliders 242 can be arranged along the moving member 25 and mounted on the guide rail 241. Thus, it is possible to ensure that the moving member 25 moves stably along the guide rail 241.

[0170] A coupling member mounting portion 253 for mounting the coupling member 262 can be formed at the lower end of the moving member 25. The end of the wire 261 can be connected to the coupling member mounting portion 253. Thus, as the moving member 25 moves, the length of the wire 261 exposed outside the upper main body 20 can be adjusted. Additionally, rollers 263 for guiding the bent wire 261 can be provided on both sides of the main body base 22.

[0171] On the other hand, a member 27 can be formed on the moving member 25 at a position corresponding to the cutting portion 212 in a pair of the moving members 25. The operating member 27 can protrude upward from the moving member 25. In particular, a handle 271 can be included in the operating member 27, and the handle 271 protrudes through the cutting portion 212.

[0172] Thus, the user can operate the handle 271 protruding through the cutting portion 212 to move the moving member 25. When the moving member 25 provided with the operating member 27 moves, the pinion 233 can rotate, and other moving members 25 engaged with the pinion 233 can also move simultaneously. By operating the moving member 25 through the operating member 27, the user can adjust the height of the lighting device 30 by adjusting the leading-out length of the wire 261.

[0173] Specifically, as Figure 13 shown, in a state where the lighting device 30 is in the highest position, the handle 271 of the operating member 27 can be located at one end (right end) of the cutting portion 212. Additionally, the moving member 25 can be located at positions on the left and right sides farthest from the upper main body 20. Thus, the wire 261 can be in a state of being maximally introduced into the interior of the upper main body 20 without being exposed to the outside. Additionally, in the state as described above, the lighting device 30 can be in a state of contacting the bottom surface of the upper main body 20.

[0174] In the state described above, if the handle 271 is grasped and moved along the cut portion 212, the moving member 25 can be moved, and by the rotation of the pinion 233, the pair of moving members 25 can be moved together. By the movement of the moving member 25, the wire 261 is drawn out from the upper main body 20, and the lighting device 30 moves downward and its height is reduced.

[0175] As Figure 14 shown, in the state where the lighting device 30 is in the lowest position, the handle 271 of the operating member 27 can be located at the other end (left end) of the cut portion 212. In addition, the moving member 25 can be located at positions closest to the left and right side ends of the upper main body 20. Therefore, the wire 261 can be in a state of being drawn out to the maximum extent outside the upper main body 20. In addition, in the state described above, the lighting device 30 can be farthest from the upper main body 20 and closest to the lower main body 10.

[0176] On the other hand, in addition to the above-described embodiments, the present invention can also be implemented as various other embodiments. Another embodiment of the present invention is characterized in that the lifting assembly includes a rotating disk, a moving member, and a connecting member. In another embodiment of the present invention, the components other than a part of the lifting assembly are the same as those in the above-described embodiment, and the same reference numerals are used for the same components and shown, and their detailed descriptions and illustrations are omitted.

[0177] Hereinafter, with reference to the drawings, another embodiment of the present invention will be described.

[0178] Figure 16 is a view showing the state of the lifting assembly when the height of the lighting device of the plant cultivation device according to another embodiment of the present invention is in the highest state. In addition, Figure 17 is a view showing the state of the lifting assembly when the height of the lighting device is in the lowest state. In addition, Figure 18 is a partial perspective view showing the operating state of the lifting assembly.

[0179] As shown in the figure, a lifting assembly 200″ can be provided on the main body base 22 of the upper main body 20 of the plant cultivation device 1 according to another embodiment of the present invention. In addition, the lifting assembly 200″ is configured to be connected to the lighting device 30 to lift the lighting device 30.

[0180] The base rib 221 can be formed on the main body base 22, and the base rib 221 can be used to form a base accommodation portion 220 for installing the lifting assembly 200″ and the guide module 24. In addition, engaging members 262 and rollers 263 can be respectively provided on the left and right sides of the base accommodation portion 220 to allow the wire 261 to enter and exit the left and right sides of the upper main body 20.

[0181] The lifting component 200″ may include a rotating disk 281 and a connecting member 282. The rotating disk 281 may be rotatably mounted on the upper main body 20. In addition, the connecting member 282 may be connected to the rotating disk 281 and the operating member 27. In addition, the rotating disk 281 may be engaged with the moving member 25 to rotate the rotating disk 281 when the moving member 25 moves.

[0182] Specifically, the rotation axis 2811 of the rotating disk 281 may be rotatably mounted at the center of the main body base 22. In addition, a pinion 2812 centered on the rotation axis 2812 may be formed on the bottom surface of the rotating disk 281. The pinion 2812 may be engaged with the rack 251 of the moving member 25.

[0183] The moving member 25 may be composed of a first moving member 25a and a second moving member 25b. The first moving member 25a and the second moving member 25b may be arranged in a pair in opposite directions with respect to the rotation axis 2812 of the rotating disk 281. In addition, a pair of the moving members 25 may be engaged with the pinion 2812 of the rotating disk 281. Therefore, as the rotating disk 281 rotates, a pair of the moving members 25 may move in opposite directions.

[0184] The moving member 25 may extend in the extending direction of the upper main body 20. In addition, the rack 251 engaged with the pinion 2812 may be formed along the moving member 25. In addition, a slider mounting portion 252 for mounting the slider 242 may be formed at one end of the moving member 25. In addition, a plurality of the sliders 242 may be arranged along the moving member 25 and mounted on the guide rail 241. Therefore, it is possible to ensure that the moving member 25 moves stably along the guide rail 241. On the other hand, the guiding module 24 may be provided with a pair of first guiding modules 24a and a pair of second guiding modules 24b.

[0185] A coupling member mounting portion 253 for mounting the coupling member 262 may be formed at the lower end of the moving member 25. The end of the wire 261 may be connected to the coupling member mounting portion 253. Therefore, as the moving member 25 moves, the length of the wire 261 exposed to the outside of the upper main body 20 can be adjusted. In addition, rollers 263 for guiding the bent wire 261 may be provided on both sides of the main body base 22.

[0186] On the other hand, an operation member 27 may be formed at a position of one of the pair of moving members 25 corresponding to the cutout portion 212 formed at the top 21 of the main body. The operation member 27 may protrude upward from the moving member 25. In particular, the operation member 27 may include a handle 271, and the handle 271 penetrates through the cutout portion 212 and protrudes upward.

[0187] In addition, an operation member guide 284 for guiding the movement of the operation member 27 may be provided on the upper main body 20. The operation member guide 284 may be formed in a plate shape and may be disposed above the moving member 25. In addition, the operation member guide 284 may extend along the moving direction of the moving member 25. At this time, the length of the operation member guide 284 may be formed to be a size that can be disposed between the coupling member 262 and the end of the rotary disk 281.

[0188] On the other hand, a guide groove 2841 may be formed in the operation member guide 284. The guide groove 2841 may be formed to be a size that can accommodate the operation member 27. In addition, the guide groove 2841 may extend along the moving direction of the operation member 27. Therefore, when the operation member 27 is moved and operated, the operation member 27 may reciprocate along the guide groove 2841. In addition, the handle 271 of the operation member 27 may protrude more upward than the guide groove 2841 and may protrude upward from the top 21 of the main body through the cutout portion 212.

[0189] In addition, the operation member 27 and the rotary disk 281 may be connected by a connecting member 282. One end of the connecting member 282 may be axially coupled to the operation member 27, and the other end may be axially coupled to the rotary disk 281. The other end of the connecting member 282 may be connected to the rotary disk 281 and may be axially coupled on the side closer to the end of the rotary disk 281 away from the rotation axis 2812 of the rotary disk 281. Therefore, when the operation member 27 is horizontally moved and operated, the rotary disk 281 may be rotated by the connecting member 282.

[0190] Therefore, the user can move the operation member 27 by operating the handle 271 exposed through the cutout portion 212. By the movement of the operation member 27, the rotary disk 281 can be rotated, and the pair of moving members 25 engaged with the pinion 2812 of the rotary disk 281 can be moved simultaneously. The user can move the moving member 25 by operating the operation member 27, and can adjust the height of the lighting device 30 by adjusting the lead-out length of the wire 261.

[0191] Specifically, as Figure 16As shown, in the state where the lighting device 30 is at the highest position, the handle 271 of the operating member 27 can be located inside the guide groove 2841. In addition, the moving member 25 can be located at the position farthest from the left end of the upper body. Therefore, the wire 261 can be in a state where it is maximally introduced into the interior of the upper body 20 without being exposed to the outside. In addition, in the state as described above, the top surface of the lighting device 30 can be in contact with the bottom surface of the upper body 20.

[0192] In the state as described above, if the handle 271 is grasped and moved in the left direction along the guide groove 2841, the moving member 25 moves together with the operating member 27, and at the same time, the rotary disk 281 can be rotated by the connecting member 282. In addition, by the rotation of the rotary disk 281, the pair of moving members 25 can move in opposite directions at the same time. By the movement of the moving member 25, the wire 261 is drawn out from the upper body 20, and the lighting device 30 moves downward and its height is reduced.

[0193] As Figure 17 shown, in the state where the lighting device 30 is at the lowest position, the handle of the operating member 27 can be located on the left side of the guide groove 2841. In addition, the moving member 25 can be located at the position closest to the left end of the upper body 20. Therefore, the wire 261 can be in a state where it is maximally drawn out to the outside of the upper body 20. In addition, in the state as described above, the lighting device 30 can be farthest from the upper body 20 and closest to the lower body 10.
