[0060] Figure 1 It is a perspective view of the plant cultivation device according to the first embodiment of the present invention.

[0061] As shown in the figure, the plant cultivation device 1 according to the embodiment of the present invention may include a main body 2 that forms a cultivation space 100 for cultivating plants. In addition, the main body 2 may include a lower main body 10 and an upper main body 20.

[0062] The lower body 10 can extend longitudinally in the left - right direction. The lengths of the left and right sides of the lower body 10 can be greater than the width in the front - rear direction. The lower body 10 forms the bottom surface of the plant cultivation device 1 and can be configured to cultivate plants. Specifically, a tray part 33 can be provided on the top surface 113 of the lower body 10.

[0063] The tray part 33 can be configured to accommodate a container for plant cultivation, or a package (including seeds and a culture medium), or a pod. Additionally, a receiving groove 331 is formed in the tray part 33, and plants for cultivation can be directly placed, or a container or a pod can be placed. Water can be supplied to the tray part 33, and by supplying water into the inside of the receiving groove 331, water supply to the cultivated plants is constituted, either directly or indirectly.

[0064] The tray part 33 can be detachably provided on the lower body 2. Additionally, in a state where the tray part 33 is installed in a tray opening 114 on the top surface 113 of the lower body 2, the top surface of the tray part 33 can form the same plane as the top surface of the lower body 2. Additionally, the receiving groove 331 can be exposed through the top surface of the lower body 2.

[0065] In an embodiment of the present invention, an example is given where three receiving grooves 331 are formed in the tray part 33. However, the tray part 33 is not limited thereto and can have various shapes capable of accommodating water and cultivated plants.

[0066] Additionally, a plurality of the tray parts 33 can be provided on the top surface of the lower body 2. As an example, two tray parts 33 can be continuously arranged. Additionally, a discharge port 521 described later can be located between the tray parts 33 on both sides. At this time, the position of the discharge port 521 can be at the center of the top surface of the lower body 2. The end of the exhaust duct 52 can be exposed to the cultivation space 100 through a discharge port opening 115 formed in the top surface 113 of the lower body 2.

[0067] Various components including a humidification module 40 can be arranged in the internal space 110 of the lower body 2. Later, the internal structure of the lower body 2 will be described in detail.

[0068] Additionally, a main body opening 111 exposing a part of the humidification module 40 can be formed in the lower body 2. Through the main body opening 111, a housing 41 constituting the humidification module 40 can be exposed. Additionally, at least a part of the humidification module 40 can enter and exit through the main body opening 111. Therefore, it is possible to easily replace or clean a filter 43 inside the humidification module 40 without disassembling the lower body 2.

[0069] The upper main body 20 can be disposed above the lower main body 10 and can 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 corresponding to the size of the top surface of the lower main body 10.

[0070] A cultivation space 100 can be formed between the lower main body 2 and the upper main body 2. The cultivation space 100, as the space actually constituting cultivation, can be shielded by the cover 32. Additionally, the cover 32 can shield between the lower main body 2 and the upper main body 2. That is, through the lower main body 2, the upper main body 2, and the cover 32, the appearance of the plant cultivation device 1 can be formed. Additionally, since the cover 32 is formed of a transparent material, the interior of the cultivation space 100 can be seen through the cover 32. Additionally, the cover 32 can be composed of a plurality of components, and at least a part thereof can be provided in an openable / closable or detachable manner.

[0071] As an example, the cover 32 can include a front cover 321 that shields the front of the cultivation space, a rear cover 322 that shields the rear of the cultivation space, and side covers 323, 324 that shield the left and right side surfaces of the cultivation space.

[0072] Additionally, the side covers 323, 324 can be configured to be detachable. Therefore, the side covers 323, 324 can be separated to perform operations such as putting in or taking out plants in the cultivation space 100 and supplying water.

[0073] Additionally, an illumination device 21 for irradiating light to the cultivation space 100 can be provided on the upper main body 2. The illumination device 21 can be disposed on the bottom surface of the upper main body 2. The illumination device 21 and the top surface of the lower main body 2 are arranged to face each other so that the light irradiated from the illumination device 21 can shine on the cultivated plants disposed on the tray portion 33.

[0074] Additionally, an operation portion 221 can also be formed on the top surface of the upper main body 2. The operation portion 221 is used to operate the actions of the plant cultivation device 1 and can adjust the actions of the illumination device 21 or the humidification module 40.

[0075] On the other hand, the plant cultivation device 1 can further include a frame 31. The frame 31 can be connected between the upper main body 20 and the lower main body 10. A pair of the frame 31 can be disposed on the left and right sides. Additionally, the frame 31 can 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 31 can be located at the left and right side ends of the rear surfaces of the lower main body 10 and the upper main body 20. Furthermore, the frame 31 can be fixed to a wall surface, and the plant cultivation device 40 can be installed in a form of being hung on the wall surface.

[0076] A hollow 311 may be formed inside the frame 31. Thus, through the frame 31, the interior of the lower body 10 and the interior of the upper body 20 can communicate with each other. Additionally, at least one of the frames 31 on the left and right sides may be provided with an electric wire 312. That is, the electric wire can be led from the lower body 10 through the frame 31 to the upper body 20. Further, the electric wire 312 can be connected to an electrical component provided inside the upper body 20 to supply power. As an example, the electric wire 312 can be connected to the lighting device 21.

[0077] Hereinafter, with reference to the drawings, the structure of the lower body 2 will be described in detail.

[0078] Figure 2 It is a partial perspective view showing the inside of the lower body of the plant cultivation device.

[0079] As shown in the figure, the lower body 2 can form the lower part of the plant cultivation device 1. Additionally, the tray portion 33 can form a part of the top surface of the lower body 2. The humidification module 40, the intake duct 53, and the exhaust duct 52 can be provided in the internal space 110 of the lower body 2.

[0080] Specifically, the water supply module 50 is used to supply water to the humidification module 40 after draining the water stored in the tray portion 33, and can be provided below the tray portion 33. Additionally, the water supply module 50 can include a pipe 55 connected to the tray portion 33 and a valve 54 for opening and closing the pipe 55.

[0081] When a plurality of the tray portions 33 are provided, a plurality of the pipes 55 can also be provided. Additionally, the pipe 55 can branch and be respectively connected to the tray portions 33. Further, a pipe connection portion 332 connected to the end of the pipe 55 can be provided on the bottom surface of the tray portion 33.

[0082] Specifically, the pipe 55 can include a connection pipe 551 connected to the pipe connection portion 332, a branch pipe 552 connecting a plurality of the connection pipes 551 to one pipe, and a water outlet pipe 553 connected to the valve 54 to supply water to the humidification module 40. Additionally, each of the pipes 551, 552, and 553 can be connected to each other using fittings 56.

[0083] Further, the valve 54 can be connected to the pipe 55. The valve 54 can open and close the pipe 55 to selectively supply water to the humidification module 40. As an example, the valve 54 generally remains closed and can be opened when the humidification module 40 operates.

[0084] On the other hand, the humidification module 40 can be connected to only any one of the plurality of tray parts 33. In addition, since the water stored in the tray part 33 is supplied to the humidification module 40, the tray part 33 can be referred to as a water storage part.

[0085] The outlet of the water supply module 50, that is, the outlet of the water outlet pipe 553, can be located directly above the humidification module 40 in the vertical direction. Therefore, the water discharged from the water supply module 50 can fall onto the top surface of the humidification module 40.

[0086] The humidification module 40 can include a housing 41 and a filter 43. The housing 41 can store the water discharged through the water supply module 50. The filter 43 is accommodated inside the housing 41, and the water discharged through the water supply module 50 can pass through the filter 43. During this process, the filter 43 can absorb water.

[0087] In addition, the humidification module 40 can further include a fan 51. The fan 51 can be provided on one side of the housing 41. The fan 51 can generate a flow of air so that external gas can flow in, pass through the humidification module 40, and supply humidified air to the cultivation space 100.

[0088] The fan 51 can be provided on one side of the housing 41 and formed at a position corresponding to a housing opening 413a described later, so that the inflowing air can be humidified by passing through the filter 43. That is, the humidification module 40 can be configured as an evaporative humidifier.

[0089] The intake pipe 53 can allow air outside the plant cultivation device 1 to flow in. In addition, the intake pipe 53 can connect the outer side surface of the lower main body 2 and the housing 41. The inlet of the intake pipe 53 can be exposed to the side surface of the lower main body 2. That is, an external gas inlet 531 can be formed on the side surface of the lower main body 2, and the external gas inlet 531 can communicate with the inlet of the intake pipe 53. The external gas inlet 531 can be exposed through the opening 112 of the lower main body 10. In addition, the outlet of the intake pipe 53 can communicate with the housing opening 413b. Therefore, the external gas flowing into the intake pipe 53 can flow toward the filter 43. The external gas inlet 531 can be formed in a grid or mesh shape, or can be formed integrally with the intake pipe 53.

[0090] On the other hand, the fan 51 may be disposed between the inlet of the exhaust duct 52 and the housing 41. The fan 51 may be formed in a box fan structure, and the input side of the fan 51 may communicate with the housing opening 413a. Additionally, the inlet of the exhaust duct 52 may communicate with the output side of the fan 51. Further, the outlet of the exhaust duct 52 may be connected to the discharge port 521 on the top surface of the lower main body 2. The humidified air may be supplied to the cultivation space 100 through the discharge port 521.

[0091] The exhaust duct 52 may be in a direction where the inlet and the outlet cross each other. Additionally, the exhaust duct 52 may be formed by bending. Further, the size of the outlet of the exhaust duct 52 may be smaller than the size of the inlet. The outlet of the exhaust duct 52 may be formed in a shape corresponding to the discharge port 521. Additionally, the discharge port 521 may be formed in a grid or mesh shape, or may be integrally formed with the exhaust duct 52.

[0092] The humidification module 40, the intake duct 53, the exhaust duct 52, and the fan 51 may be referred to as a humidification device or a vaporization humidification device.

[0093] Hereinafter, with reference to the drawings, the structure of the humidification module 40 will be described in detail.

[0094] Figure 3 is a perspective view of the humidification module. Additionally, Figure 4 is an exploded perspective view of the humidification module. Additionally, Figure 5 is Figure 3 a perspective view of a V-V' cross-section of

[0095] As shown in the figure, the humidification module 40 may include a housing 41 for storing water and a filter 43 accommodated inside the housing 41.

[0096] Specifically, the housing 41 may include a front surface 411a, a back surface 411b, a top surface 411d, a bottom surface 411e, and left and right side surfaces 411c. The front surface of the housing 41 may be exposed through the main body opening 111. Additionally, a handle 412 may be recessed and formed on the front surface of the housing 41. Thus, the user may pull out the front surface of the housing 41 exposed through the main body opening 111 to separate the humidification module 40 from the lower main body 2. The humidification module 40 may be simply separated or installed on the lower main body 2 without separating the lower main body 2, thereby ensuring convenience in washing or repairing the humidification module 40.

[0097] On the left and right side surfaces of the housing 41, the housing openings 413 may be formed. The housing openings 413 may be formed to expose at least a part of the filter 43. The housing openings 413 may be formed at a position higher than the full water level of the housing 41. As an example, the housing openings 413 may be configured to be in contact with the upper ends of the side surfaces of the housing 41.

[0098] Inside the housing 41, a filter placement portion 414 may be formed. The filter placement portion 414 supports the filter 43 from below and vertically divides the inside of the housing 41. Above and below the housing 41, a filter accommodation space 416 and a water accommodation space 410 may be formed based on the filter placement portion 414. In addition, a plurality of holes 414a are formed in the filter placement portion 414, enabling the water passing through the filter 43 to be directed to the water accommodation space 410.

[0099] In addition, a filter opening 415 may be formed on the top surface of the housing 41. The filter opening 415 is formed to be equal to or larger than the size of the filter 43 for the filter 43 to enter and exit. In a state where the filter 43 is installed, the top surface of the filter 43 may be located at the filter opening 415.

[0100] In addition, the humidification module 40 may further include a filter cover 441. The filter cover 441 may be formed to cover the filter opening 415. In addition, the filter cover 441 may cover the top surface of the filter 43. The central portion of the filter cover 441 protrudes upward, and the filter cover 441 may be inclined to be lower from the center of the filter cover 441 toward both sides. That is, inclined surfaces 442 may be formed to be inclined in opposite directions based on the center of the filter cover 441.

[0101] In addition, a plurality of cover holes 443 are formed in the inclined surface 442, enabling the water discharged from the water supply module 50 to flow along the inclined surface 442 and be evenly supplied to the filter 43. In addition, it can filter foreign substances contained in the water supplied through the water supply module 50.

[0102] At this time, the outlet of the water supply module 50 may be located directly above the central portion of the filter cover 441. The outlet of the water supply module 50 remains separated from the humidification module 40, thus preventing interference during the insertion and extraction of the humidification module 40.

[0103] A lid border 441 may be formed at the periphery of the filter lid 441. The lid border 441 may protrude in the vertical direction. Thus, water supplied to the top surface of the filter lid 441 can be guided to drain downward through the inclined surface 442. In addition, the top surface of the filter 43 may be inserted into the lower space of the filter lid 441 formed by the lid border 441.

[0104] In addition, a support member 42 may be provided on the bottom surface of the filter 43. The support member 42 may be formed to surround the lower part including the bottom surface of the filter 43. As an example, the support member 42 may include a support member bottom surface 421 that supports the bottom surface of the filter 43 and support member side surfaces 422 that extend upward from both side ends of the support member bottom surface 421 and are in contact with the left and right side surfaces of the filter 43. Thus, the lower end of the filter 43 can be inserted into the inside of the support member 42. In addition, the support member 42 may be formed of a plastic or metal material, which can prevent damage to the filter 43 formed of a relatively soft material. In addition, a plurality of holes 423 may be formed in the bottom surface of the support member 42, overlapping at least a part of the holes 414a formed in the filter placement part 414, enabling the water passing through the filter 43 to move downward.

[0105] The filter 43 may be formed in a size that can be accommodated inside the housing 41. As an example, the filter 43 may be formed in a hexahedron shape. In addition, the area in the air flow direction of the filter 43 may be larger than the area in the water supply direction. Thus, the filter 43 can ensure a sufficient amount of humidified air while enabling smooth air flow.

[0106] In addition, the filter 43 may be formed of a material that can absorb water supplied from above. As an example, the filter 43 may be formed to have a porous material such as a sponge or fabric, or a mesh structure or grid structure. The filter 43 may be formed to be able to absorb and move water and allow air to pass through.

[0107] Hereinafter, with reference to the drawings, the operation of the plant cultivation device 1 having the above-described structure will be described in detail.

[0108] Figure 6 It is a cross-sectional view showing the humidified state of the plant cultivation device.

[0109] As shown in the figure, the plant cultivation device 1 can supply water to the tray part 33 to cultivate plants. In addition, plants for cultivation may be arranged in the tray part 33.

[0110] The water stored in the tray portion 33 can be used for plant cultivation, but in the case where humidification is required, it can be supplied to the humidification module 40. The condition where humidification is required can be determined by input through the operation unit 221 of the user, or can be determined by using a humidity sensor (not shown) that senses the humidity of the cultivation space 100.

[0111] If it is determined to operate the humidification module 40, the valve 54 can be opened. When the valve 54 is opened, the water stored in the tray portion 33 can move downward along the pipe 55.

[0112] In addition, the outlet of the water outlet pipe 553 is located above the filter cover 441 to supply water to the filter 43. The water discharged from the water outlet pipe 553 can wet the top surface of the filter 43 and move downward through the filter 43. The filter 43 can be in a state of sufficiently absorbing water during the downward movement of water. In addition, the water that completely passes through the filter 43 can be stored in the water accommodation space 410 at the lower part of the housing 41.

[0113] In addition, by driving the fan 51, the air outside the plant cultivation device 1 flows into the intake pipe 53 through the inflow port 531. The outside air flowing along the intake pipe 53 sequentially passes through the housing opening 413b and the filter 43. At this time, the filter 43 is in a state of absorbing water, and the air passing through the filter 43 can be in a humidified state.

[0114] The humidified air passing through the filter 43 moves to the exhaust pipe 52 through the fan 51. In addition, the humidified air moving along the exhaust pipe 52 can be supplied to the cultivation space 100 through the discharge port 521 on the top surface of the lower main body 2.

[0115] As described above, the water supply of the tray portion 33 and the driving of the fan 51 can be configured simultaneously and can be continuously performed during a set time period to sufficiently humidify the cultivation space 100. In addition, the humidification amount can also be adjusted by adjusting the opening degree of the valve 54 and the rotation speed of the fan 51.

[0116] If the cultivation space 100 satisfies the set humidity, or the operation of the humidification module 40 is ended by the user operating the operation unit 221, the valve 54 is closed and the fan 51 stops.

[0117] On the other hand, through the operation of the humidification module 40, not only can the humidity inside the cultivation space 100 be adjusted, but also the ventilation through the inflow of outside air and the supply of carbon dioxide required for photosynthesis can be smoothly configured.

[0118] On the other hand, in addition to the above-described embodiments, the present invention can also be implemented as various other embodiments. The second embodiment of the present invention is characterized in that the humidification module, the intake duct, and the exhaust duct are arranged in the upper main body.

In addition, each of the pipes 551, 552, 554, and 555 can be connected to each other by pipe fittings 56. In addition, the valve 54 can be connected to the outlet of the branch pipe 552 and the inlet of the pump pipe 554. In addition, the pump 57 can be connected to the outlet of the pump pipe 554 and the inlet of the outlet pipe 555.

The outlet pipe 555 extends inside the frame 31 to the upper main body 20' and can extend above the humidification module 40. The outlet of the water supply module 50, that is, the outlet of the outlet pipe 555, can be opened on the top surface of the filter 43 above the filter 43. Therefore, the water discharged from the outlet pipe 555 can fall downward and be supplied to the humidification module 40, that is, the filter 43.

[0129] A lighting device 21' can be provided on the bottom surface of the upper main body 20'. The lighting device 21' can irradiate light for plant cultivation to the cultivation space 100.

[0130] In addition, a humidification module 40 can be provided inside the upper main body 20'. In addition, a main body opening 201 for the humidification module 40 to enter and exit can be formed on the front surface of the upper main body 20'.

[0136] Hereinafter, with reference to the drawings, the operation of the plant cultivation device according to the second embodiment of the present invention having the above-described structure will be described.

[0137] Figure 10 It is a cross-sectional view showing the humidification state of the plant cultivation device.

[0138] As shown in the figure, the plant cultivation device 1' can supply water to the tray portion 33 for the cultivation of plants. In addition, plants for cultivation can be arranged in the tray portion 33.

[0173] Hereinafter, with reference to the drawings, the operation of the plant cultivation device 1″ of the third embodiment of the present invention having the above-described structure will be described.

[0174] Figure 15 It is a cross-sectional view showing the humidified state of the plant cultivation device.

[0175] As shown in the figure, the plant cultivation device 1″ can supply water to the tray portion 33 for plant cultivation. In addition, plants for cultivation can be arranged in the tray portion 33.

[0176] The water stored in the tray portion 33 is used for plant cultivation, but in a situation where humidification is required, it can be supplied to the humidification module 40. If the operation of the humidification module 40 is determined, the valve 54 can be opened. When the valve 54 is opened, the water stored in the tray portion 33 moves downward along the pipe 55 under the action of its own weight.

[0177] In addition, the outlet of the pipe 55 is located above the filter cover 44 and supplies water from above the filter 43. The water discharged from the water outlet pipe 553 can wet the top surface of the filter 43 and move downward along the filter 43. The filter 43 can be in a state of fully absorbing water during the downward movement of the water. In addition, the water passing through the filter 43 can be stored inside the housing 41.

[0178] In addition, driven by the fan 71, the air outside the plant cultivation device 1″ flows into the intake duct 77 through the external gas inlet 771. The external air flowing along the intake duct 77 sequentially passes through the housing opening 413 and the filter 43. At this time, the filter 43 is in a state of absorbing water, and the air passing through the filter 43 can be in a humidified state.

[0179] The humidified air passing through the filter 43 moves toward the exhaust duct 70 via the fan 71. In addition, the humidified air moving along the exhaust duct 70 can be supplied to the cultivation space 100 through the discharge port 761 on the bottom surface of the upper main body 20″.

[0180] Specifically, driven by the fan 71, the humidified air discharged from the humidification module 40 sequentially flows through the second guiding portion 73 and the third guiding portion 76. In addition, the auxiliary fan is driven together when the fan 71 is driven, forcing the humidified air to flow. That is, in order to enable the humidified air to flow smoothly through the inside of the second guiding portion 73 whose diameter is reduced to pass through the frame 31, the auxiliary fan 75 is driven.

In addition, the humidification amount can also be adjusted by adjusting the opening degree of the valve 54 and the rotation speed of the fan 71 and the auxiliary fan 75.

[0183] On the other hand, through the operation of the humidification module 40, not only can the humidity inside the cultivation space 100 be adjusted, but also the ventilation through the inflow of external air and the supply of carbon dioxide required for photosynthesis can be smoothly constituted.

[0184] On the other hand, in addition to the above-described embodiments, the present invention can also be implemented as various other embodiments. The feature of the fourth embodiment of the present invention is a structure having an additional water storage portion for storing the water supplied to the humidification module. The constitution of the fourth embodiment of the present invention other than the water storage portion and the water supply module is the same as that of the above-described embodiment, and the same reference numerals are used for the same constitution and shown, and the detailed description and illustration thereof are omitted.

An illumination device 21 that irradiates light into the cultivation space 100 may be provided in the upper main body 2. Additionally, at least a part between the upper main body 2 and the lower main body 2 may be shielded by the lid 32.

[0189] On the other hand, the humidification module 40 that humidifies the cultivation space 100 may be provided in the internal space 110 of the lower main body 2. The humidification module 40 is for humidifying the inside of the cultivation space 100 and may be connected to an intake pipe 53 and an exhaust pipe 52. Additionally, a fan 51 is provided on one side of the intake pipe 53 or the exhaust pipe 52 to forcibly flow the air in the intake pipe 53, the exhaust pipe 52, and the humidification module 40. The humidification module 40, the intake pipe 53, the exhaust pipe 52, and the fan 51 are collectively referred to as a humidification device or a vaporization type humidification device.

[0190] One end of the opening of the exhaust pipe 52 may communicate with an external gas inlet 531 that opens outside the lower main body 2, and the other end of the opening of the exhaust pipe 52 may communicate with the humidification module 40. Additionally, one end of the opening of the exhaust pipe 52 may communicate with an outlet 521 that opens into the cultivation space 100, and the other end may face the humidification module 40. Further, the fan 51 may connect the exhaust pipe 52 and the humidification module 40. The inlet 531 and the outlet 521 may both be formed in the lower main body 20.

That is, the humidification module 40 may have a structure in which a filter 43 is provided inside a housing 41, and may be configured such that water supplied from above wets the filter 43. In addition, water passing through the filter 43 may be stored in the lower part of the humidification module 40. In addition, the housing 41 may communicate with the intake duct 53 and the exhaust duct 52. Therefore, when the fan 51 is driven, external air may pass through the filter 43, be humidified, and then be supplied to the cultivation space 100.

[0192] The humidification module 40 may be detachable from the lower body 2. As an example, the humidification module 40 may be inserted and installed or detached on one side of the opening of the lower body 2.

[0193] On the other hand, a water tank 12 may also be provided in the lower body 2. The water tank 12 stores water supplied to the humidification module 40. Therefore, the water tank 12 may be referred to as a water storage unit. The water tank 12 and the tray unit 33 may be formed separately. In addition, at least a part of the water tank 12 may be exposed to the outside of the lower body 2, and the water tank 12 may have a structure capable of supplying water to a user.
