The cover rotation axis 721, which becomes the rotation axis of the tank cover 72, may be formed on both left and right sides of the rear end of the cover plate 721, and can be rotated on the cover connection portion 712 of the tank body 71. can be combined Accordingly, the tank cover 72 is rotatably mounted on the tank body 71, and the receiving space 710 can be opened and closed by rotation.

The cover guide portion 722 protrudes downward from the lower surface of the cover plate 721 and may be formed in a shape corresponding to the open upper surface of the receiving space 710. Accordingly, when the tank cover 72 is closed, the cover guide portion 722 may contact the inner surface of the receiving space 710.

Additionally, the cover guide portion 722 extends further downward at the rear than the front, and both sides may have a slope that decreases toward the front. In particular, the rear side of the cover guide portion 722 may be extended to be located in the inner area of the receiving space 710 in an open state. Therefore, when water droplets formed on the back of the tank cover 72 flow down by opening the tank cover 72, they can flow into the receiving space 710 through the cover guide part 722. . Therefore, it is possible to prevent water from leaking out of the water tank 70 when the tank cover 72 is opened.

Meanwhile, a water collecting portion 723 may be formed in the inner area of the cover guide portion 722. The water collecting part 723 may be made of grooves small enough for water droplets to form, and may be formed to occupy most of the inner area of the cover guide part 722. Therefore, even if condensation occurs on the back of the tank cover 72, water droplets can be maintained in the water collection portion 723 due to the surface tension of the water, and when the tank cover 72 is opened, a large amount of water is released. It can be prevented from flowing along the tank cover 72.

Additionally, a tank water outlet 78 may be formed in the rear central portion of the tank cover 72. The tank outlet 78 may form a flow path for supplying water from the water tank 70 to the outside of the water tank 70, and extends from the inner bottom of the tank cover 72 to supply the water. It may be formed to protrude from the rear of the tank 70.

Meanwhile, the tank water outlet 78 may be composed of a first water outlet 781 and a second water outlet 782. The first water outlet 781 may extend from the lower surface of the tank cover 72 to the lower surface of the tank body 71. At this time, at least a portion of the lower end of the first water outlet 781 may be spaced apart from the lower surface of the tank body 71 to form an inlet through which water flows into the tank body 71.

Additionally, the second water outlet 782 may extend rearward from the top of the first water outlet 781, and may extend rearward through the tank body 71. At this time, the second water outlet 782 may protrude through the water outlet groove 783. In addition, the second water discharge part 782 can be inserted into the fitting part 811 when the water tank 70 is inserted so as to communicate with the water tank 70 and the sub tank 82. .

Meanwhile, the tank outlet 78 may be formed integrally with the tank cover 72. At least a portion of the tank cover 72 may be injection-molded from a plastic material, and the tank water outlet 78 may be molded together with the tank cover 72 when molding the tank cover 72 . As an example, it may be formed together with the cover plate 721.

Accordingly, the tank outlet 78 does not form a joint where the water can leak, and maintains a low pressure state when the water inside the water tank 70 is sucked, so that the pump 83 is driven. Ensure that a set amount of water is accurately sucked through the tank outlet 78. If the tank outlet 78 has a structure in which the first outlet 781 and the second outlet 782 are separately formed and coupled to the tank cover 72, separate sealing may be required. And due to assembly distribution, outside air may be introduced when the pump 83 is driven. If water and air are mixed into the tank outlet 78 during the suction process by driving the pump 83, the normal operation of the pump 83 is interrupted by the air flowing into the pump 83. You may. However, in this embodiment, the tank outlet 78 is formed integrally with the tank cover 72 and does not have any assembly parts, thereby preventing the possibility of such problems occurring. In addition, it may be possible for the cover plate 721, the cover guide part 722, the water collection part 723, and the tank water outlet part 78, which constitute the tank cover 72, to be integrally formed by injection molding.

The water of the water tank 70 discharged through the tank outlet 78 can be supplied to the cultivation shelf 30 through the sub tank 82 and the pump 83 and through the water supply pipe 84. there is.

Hereinafter, the structure of the sub tank 82 will be examined in more detail with reference to the drawings.

Figure 13 is a perspective view of a sub tank according to an embodiment of the present invention. And, Figure 14 is an exploded perspective view of the sub tank.

The sub tank 82 is intended to ensure operational reliability of the pump 83, and the inlet side of the pump 83 is always filled with water to avoid problems such as air being mixed in when the pump 83 is driven. It is possible to prevent a problem in which the pump 83 cannot discharge a certain amount of water.

Accordingly, the water contained within the sub tank 82 maintains a constant level, and must pass through the sub tank 82 before being supplied to the pump 83. At this time, the capacity of the sub tank 82 is required for the initial startup of the genital pump 83, and the sterilization effect can be guaranteed by the UV lamp (UV-LED, 824) provided in the sub tank 82. Quantity can be accommodated. As an example, the amount of water contained within the sub tank 82 enables initial operation of the plurality of pumps 83, and the capacity capable of effective sterilization by the UV lamp 824 may be 300 cc, and the sub tank 82 has a capacity of 300 cc. The tank 82 may be formed to provide a space within which 300 cc of water can be accommodated.

In addition, the sub tank 82 maintains a constant water level for the initial operation of the pump 83, and for this purpose, when the water level in the water tank 70 becomes low, the operation of the pump 83 is stopped. This can prevent the water inside the sub tank 82 from falling below the set water level.

Looking at the structure of the sub tank 82 in detail with reference to the drawings, the sub tank 82 may include a sub body 821 and a sub cover 822. In addition, the sub cover 822 is equipped with a UV lamp 824 that sterilizes the water inside the sub tank 82 by irradiating ultraviolet rays (UV) to sterilize the water contained inside the sub tank 82. there is.

In detail, the sub-body 821 may be formed in a square cylindrical shape with an open upper surface. And, water to be supplied to the pump 83 is maintained inside the sub-body 821.

Also, a body receiving part 821a may be formed on the upper part of the sub-body 821 to be connected to the fitting part 811. The body intake part 821a may protrude forward, and may be inserted into the fitting part 811 to communicate with the water tank 70.

The internal water level of the sub-body 821 may be maintained at or higher than the level of the body intake part 821a. Therefore, the space between the body inlet part 821a and the tank outlet part 78 is maintained in a state filled with water without air, and when the pump 83 is driven, water in the water tank 70 is immediately released. It can be allowed to flow in. In other words, a vacuum state can be maintained to prevent air from entering the flow path from the inside of the water tank 70 to the input side of the pump 84. Additionally, the interior of the sub body 821 may be configured to maintain a full water level or a set water level.

A body outlet portion 821b may be formed at the bottom of one side of the sub-body 821. The body outlet portion 821b may be connected to the pump 83, and becomes a passage through which water flows into the sub-body 821 when the pump 83 is driven. The body water outlet portion 821b may be configured to correspond to the number of pumps 83.

As an example, the body water outlet part 821b is composed of two upper outlets and a lower outlet part and can be connected to the upper pump 83a and the lower pump 83b through pipes, respectively. With this structure, independent operation of the upper pump 83a and lower pump 83b can be guaranteed, and the upper cultivation shelf 30a can be controlled by controlling the operation time of the upper pump 83a and lower pump 83b. ) and the lower cultivation shelf (30b) can be supplied with an accurate amount of water.

A body coupling portion 821d protruding outward may be formed at the top of the sub body 821. The body coupling portion 821d may be coupled to the cover coupling portion 822b formed on the sub cover 822. A sealing structure may be provided between the sub-body 821 and the sub-cover 822, and thus the interior of the sub-body 821 may be coupled in a sealed state.

The sub cover 822 may be formed in a shape corresponding to the open upper surface of the sub body 821, and may be combined with the sub body 821 to shield the open upper surface of the sub body 821. there is.

In addition, the sub cover 822 may be equipped with an UV lamp 824 that can sterilize the water inside the sub body 821 by irradiating ultraviolet rays into the sub body 821. The UV lamp 824 may include a UV LED 824b that irradiates ultraviolet rays, and a UV PCB 824a on which the UV LED 824b is mounted and controls the operation of the UV LED 824b.

In detail, a downwardly recessed cover depression 822a may be formed on the upper surface of the sub cover 822. Also, a depression opening 822c may be formed inside the cover depression 822a. Additionally, a PCB cover 823 may be mounted inside the cover depression 822a. The PCB cover 823 allows the UV lamp 824 to be fixedly mounted, and can be exposed upward while mounted on the sub cover 822.

The PCB cover 823 may be formed in a shape corresponding to the cover depression 822a, and a screw penetrating the PCB cover 823 is fastened to the cover depression 822a to secure the PCB cover 823. ) may be fixedly mounted on the sub cover 822.

In addition, a lamp mounting portion 823a on which the UV lamp 824 is fixedly mounted can be formed on the PCB cover 823. The lamp mounting portion 823a extends upward along the circumference of the UV lamp 824 and may secure the UV lamp 824 therein.

The UV PCB 824a may be fixedly mounted on the lamp mounting portion 823a, and at least a portion of the lamp mounting portion 823a is exposed to the upper surface of the PCB cover 823, that is, the upper surface of the sub cover 822. It can be. Additionally, the externally exposed portion of the UV PCB 824a can be connected to wires and connectors.

A cover opening 823b corresponding to the recessed opening 822c may be formed in the PCB cover 823. The cover opening 823b may communicate with the recess opening 822c. Also, when the UV lamp 824 is mounted, the UV LED 824b constituting the UV lamp 824 may be located inside the cover opening 823b.

An LED cover 825 is provided on the lower surface of the recessed opening 822c to shield the opened lower surface of the recessed opening 822c. The LED cover 825 may be made of transparent glass or plastic material to allow ultraviolet rays emitted from the UV LED 824b to pass through. Additionally, it is possible to prevent water inside the sub tank 82 from reaching the UV LED 824b.

Therefore, when the UV LED (824b) is turned on, the light emitted from the UV LED (824b) enters the inside of the sub tank 82 through the cover opening (823b), the recessed opening (822c), and the LED cover (825). can be investigated.

Of course, if necessary, the sub tank 82 may be equipped with another sterilizing device capable of sterilizing stored water in addition to the UV lamp 824.

Hereinafter, the arrangement of the cultivation shelf 30 and the water supply module and drainage module will be discussed in more detail with reference to the drawings.

Figure 15 is a perspective view of a cultivation shelf and a water supply and drainage module, which are components of the plant cultivation device. And, Figure 16 is a perspective view of the water supply module and drainage module. And, Figure 17 is a plan view showing the connection relationship between the water tank, sub tank, and pump.

As shown in the drawing, a plurality of cultivation shelves 30 may be arranged vertically. As an example, the cultivation shelf 30 may include an upper cultivation shelf 30a disposed above and a lower cultivation shelf 30b disposed below. The upper cultivation shelf 30a may be called a first cultivation shelf, and the lower cultivation shelf 30b may be called a second cultivation shelf.

The upper cultivation shelf (30a) and the lower cultivation shelf (30b) can be spaced apart by a set interval, and the space above the upper cultivation shelf (30a) and the space above the lower cultivation shelf (30b) can be used for plants to grow. They can be spaced apart to ensure sufficient height.

In addition, the water supply module and the drainage module disposed on both left and right sides of the cultivation shelf 30 may be connected to the water tank 70. Therefore, as water circulates between the water tank 70 and the cultivation shelf 30, the right amount of water and nutrients can be supplied to the seed package 90 at the right time.

The water supply module may be located on the right side of the cultivation shelf 30 where the water supply unit 316 is formed. Additionally, the water supply module may include the pump 83 and the water supply pipe 84. The pump 83 and the water supply pipe 84 may be configured to independently supply water to the upper cultivation shelf (30a) and the lower cultivation shelf (30b). As an example, the pump 83 includes an upper pump 83a and a lower pump 83b, and the water supply pipe 84 may include an upper water supply pipe 84a and a lower water supply pipe 84b.

The pump 83 can control the amount of water supplied to the cultivation shelf 30 and ensure that a fixed amount of water is supplied. As an example, the pump 83 can be operated 8 times a day, that is, at 3-hour intervals, and allows approximately 1 liter of water to be supplied per water supply. At this time, the amount of water supplied can be controlled through the operating time of the pump 83. Of course, if necessary, the water supply module may include a flow sensor, and the operation of the pump 83 may be controlled according to the detection of the flow rate through the flow sensor to supply a fixed amount of water.

Meanwhile, at least part of the water supply pipe 84 may be made of a metal pipe. In particular, the end of the water supply pipe 84 on the water outlet side adjacent to the cultivation space 100 can be bent to maintain its position and shape, and thus always maintains the correct water supply position when supplying water to the cultivation shelf 30. It is possible to prevent water from leaking or splashing to the outside of the cultivation shelf (30).

The end of the water supply pipe 84 may extend toward the water supply unit 316 at the rear end of the cultivation shelf 30. The water supply unit 316 protrudes backward from the rear end of the cultivation shelf 30 and may have an open upper surface. Additionally, the end of the water supply pipe 84 is located above the open upper surface of the water supply unit 316 and may be bent to face the open upper surface of the water supply unit 316.

Meanwhile, the water supply module may include the sub tank 82. The sub tank 82 is located on the side of the pump 83 and may be located behind the water tank 70. The sub tank 82 may be connected to the water tank 70 and the pump 83, and may allow water from the water tank 70 to be supplied to the pump 83.

Additionally, the sub tank 82 may be configured to maintain a set water level at all times. Therefore, it is possible to prevent air from flowing in when the pump 83 is stopped and restarted, and the inlet side of the pump 83 is always filled with water. Therefore, the pump 83 can ensure that an accurate amount of water is supplied through time control. In addition, by using the small pump 83, reliable operation can be guaranteed even when used repeatedly for a long period of time.

The drainage module may be located on the left side of the cultivation shelf 30 where the opening and closing member 36 is provided. The drain module may include a drain tray 85 and a drain pipe 89. The drain tray 85 is disposed below the opening and closing member 36 that opens and closes the drain hole 319a of the cultivation shelf 30, and receives water from the cultivation shelf 30 drained from the drain hole 319a. It is formed so that

The opening and closing member 36 is formed to open and close the drain hole 319a by rotation, and can be operated by a driving device 86 provided above the opening and closing member 36. The driving device 86 includes an upper driving device 86a for opening the opening and closing member 36 of the upper cultivation shelf 30a, and a lower driving device for opening the opening and closing member 36 of the lower cultivation shelf 30b. It may include device 86b.

For example, the driving device 86 has a structure in which the rod moves up and down by driving a motor, and when moved downward, the drain hole 319a can be opened by pressing and rotating the opening and closing member 36. Then, when the rod is moved upward, the opening and closing member 36 returns to its original position and closes the drain hole 319a again.

That is, water from the cultivation shelf 30 can be drained by the operation of the driving device 86. The driving device 86 may be operated after a set time has elapsed after water is supplied to the cultivation shelf 30. The set time may be set to a time during which water supplied to the cultivation shelf 30 and supplied to the seed package 90 can be sufficiently supplied to the seeds. The seeds or plants inside the seed package 90 can absorb a sufficient amount of water within a set time after water is supplied into the seed package 90.

As an example, the set time may be set to 1 hour to 1 hour and 30 minutes. Therefore, the cultivation shelf 30 can maintain water supply for at least a set time, and after the set time has elapsed, all the water inside the cultivation shelf 30 is drained by driving the driving device 86. do. Accordingly, the inside of the cultivation shelf 30 and the seed package 90 remain emptied of water until re-watering begins, and mold or green algae does not occur inside the cultivation space 100.

In particular, the blower 50 is driven inside the cultivation space 100, and the water inside the cultivation shelf 30 can be more effectively removed through air circulation by the blower 50. During the period from completion of drainage until re-watering begins, the contaminated environment of the cultivation space 100 can be eliminated.

The setting time may be adjusted depending on the type of crop. If there is a large amount of water suitable for the plants being grown, it may be possible to adjust the set time to lengthen the watering time or allow watering to occur more frequently.

Meanwhile, when the water level inside the cultivation shelf 30 exceeds the appropriate water level, the driving device 86 is driven to forcibly drain the water from the cultivation shelf 30 regardless of the set time to remove the water from the cultivation shelf 30. This can prevent internal water from overflowing.

The drain tray 85 may be connected to the drain pipe 89. The drainage tray 85 may serve as a buffer that primarily accommodates water discharged from the cultivation shelf 30. Additionally, the drain tray 85 can be formed to have a predetermined area, and can prevent water falling during the draining process from splashing or overflowing. Additionally, the water discharged from the cultivation shelf 30 can be guided toward the drain pipe 89 without overflowing.

The drainage tray 85 may include an upper drainage tray 85a provided below the upper cultivation shelf 30a and a lower drainage tray 85b provided below the lower cultivation shelf 30b. Additionally, the upper drain tray (85a) and lower drain tray (85b) may be connected to the drain pipe (89).

The drain pipe 89 guides water from the drain tray 85 to the water tank 70, and includes a drain guide pipe 87 connected to the drain tray 85 and the drain guide pipe 87. and a drain tube 88 connecting the water tank 70.

The drain guide pipe 87 is connected to both the upper drain tray 85a and the lower drain tray 85b, and may extend in the vertical direction. The drain guide pipe 87 may be formed to have sufficient internal space to prevent overflow or backflow even if a large amount of water is supplied from the drain tray 85, and may have a larger cross-sectional area than the drain tube 88. It can be formed as follows.

The upper end of the drain guide pipe 87 is connected to the upper drain tray 85a and may extend further downward than the lower drain tray 85b. Additionally, the lower end of the drainage guide pipe 87 may be bent forward and may extend forward.

The drainage guide pipe 87 may be disposed inside the side of the cultivation space 100. That is, the drainage guide pipe 87 is accommodated in the recessed portion of the side plate 122, so that the drainage guide pipe 87 does not protrude inside the cultivation space 100 or is exposed when viewed from the front.

The drain tube 88 may be connected to the lower end of the drain guide pipe 87. The drain tube 88 may be formed in a tube shape with a diameter smaller than the cross-sectional area of the drain guide tube 87, and may be made of a flexible material. Accordingly, the drain tube 88 may extend from the end of the drain guide pipe 87 to the water tank 70 and may be disposed inside the pump cover 81.

Meanwhile, a drain valve 881 may be provided at the extended end of the drain tube 88. The drain valve 881 may be exposed to the outside of the pump cover 81 and may be connected to the valve insertion hole 744a of the water tank 70 when the water tank 70 is installed.

In detail, the drain valve 881 has the same structure as a check valve, and can be opened by being inserted into the valve insertion hole 744a when the water tank 70 is mounted. Due to the opening of the drain valve 881, the drain pipe 89 and the water tank 70 may be in communication, and water drained from the cultivation shelf 30 may flow into the water tank 70. You can.

And, when the water tank 70 is withdrawn, the drain valve 881 is released from contact with the water tank 70 and closed, thereby preventing the water inside the drain pipe 89 from draining. . Therefore, it is possible to prevent the inside of the cultivation space 100 from being polluted by drainage when the water tank 70 is pulled out.

In this way, the water tank 70 can be connected to the water supply module and the drainage module, and the water in the water tank 70 is supplied to the upper cultivation shelf 30a and the lower cultivation shelf 30b by the water supply module. The water in the upper cultivation shelf 30a and the lower cultivation shelf 30b can be returned to the water tank 70 by the drainage module. That is, it may have a structure that allows water to circulate between the water tank 70 and the cultivation shelf 30.

Hereinafter, with reference to the drawings, we will look at the path through which water drained into the water tank flows in more detail.

Figure 18 is a perspective view taken along line XVIII-XVIII' of Figure 17.

As shown, the water tank 70 may be placed on the bottom of the cultivation space 100 and in front of the pump cover 81. The water tank 70 may have a height corresponding to the height of the upper surface of the pump cover 81 when the tank cover 72 is closed. In addition, the lower cultivation shelf 30b may be disposed adjacent to and above the water tank 70 and the pump cover 81.

In addition, when the water tank 70 is completely retracted and adjacent to the front of the pump cover 81, water can be supplied to the cultivation shelf 30 and water discharged from the cultivation shelf 30 can be recovered. I do it.

A drain valve 881 connected to the end of the drain tube 88 may be mounted on the front of the pump cover 81. The end of the drain valve 881 may protrude forward through the front of the pump cover 81, and may protrude to the inside through the rear of the water tank 70 when the water tank 70 is fully retracted. It can be inserted as .

In detail, the drain valve 881 may be formed by a rear case 881a connected to the drain tube 88 and a front case 881b coupled to the open front surface of the rear case 881a. there is. The front case 881b may protrude forward through the pump cover 81, and the protruding end may be inserted into the valve insertion hole 744a at the rear of the water tank 70.

Additionally, the valve opening member 881c may be supported by an elastic member 881d inside the rear case 881a and the front case 881b. The valve opening member 881c may be formed in a poppet-like shape, and a rod may be formed in the front-back direction, and a shade may be formed around the rod in contact with the inner surface of the front case 881b to open and close the flow path. Accordingly, the valve opening member 881c can open and close the drain valve 881 while moving in the front-back direction inside the drain valve 881.

The valve opening member 881c is supported from the rear by the elastic member 881d to maintain the drain valve 881 in a closed state. Also, when the valve opening member 881c is closed, the front end of the valve opening member 881c may protrude through the front case 881b. At this time, the outer diameter of the front end of the valve opening member 881c may have a smaller diameter than the opening of the front end of the front case 881b. Additionally, the valve opening member 881c may protrude further than the front end of the front case 881b, which protrudes forward of the pump cover 81 when the drain valve 881 is closed.

Meanwhile, a valve insertion hole 744a may be formed in the rear 744 of the water tank 70 corresponding to the drain valve 881. The valve insertion hole 744a may be formed at a corresponding position so that the front case 881b of the drain valve 881 can be inserted when the water tank 70 is inserted.

A display cover 741 may be formed at a portion where the front end of the drain valve 881 is inserted. The display cover 741 indicates the water level of the water tank 70, and may be formed on the inside of the water tank 70, spaced apart from the rear 744 of the tank body 71. The display cover 741 may extend from the bottom of the tank body 71 to the top of the tank body 71. Additionally, a display opening 741c cut in the vertical direction may be formed in the display cover 741. Water inside the tank body 71 may flow into the space spaced between the display cover 741 and the tank body 71 through the display opening 741c.

Additionally, a tank floater 742 may be formed in the space between the display cover 741 and the tank body 71. The tank floater 742 may be made of a foam material that floats on water, and may be formed to have an identifiable color. Accordingly, the tank floater 742 can be moved up and down depending on the water level of the tank body 71, and the water level of the tank body 71 can be displayed intuitively through the display opening 741c.

Additionally, the tank floater 742 may include a magnet, and a tank water level detection device 743 may be provided on the front of the pump cover 81 corresponding to the display cover 741. The tank water level detection device 743 can detect the water level of the water tank 70 by detecting changes in the magnetic field of the magnet of the tank floater 742. As an example, the tank water level detection device 743 may be placed at the bottom of the pump cover 81, so when the magnet is located at a position corresponding to the tank water level detection device 743, the water tank ( 70) can detect that the water level is low. When the water level in the water tank 70 is detected to be low, the control unit of the plant cultivation device 1 may notify the user to replenish water and, if necessary, stop water supply to the cultivation shelf 30. It may be possible.

Meanwhile, when the water tank 70 is fully inserted, the front case 881b is inserted into the valve insertion hole 744a, and the front end of the opening and closing member 36 is connected to the display cover 741. It comes into contact with the rear and is pressed. At this time, the opening and closing member 881c is moved rearward to open the drain valve 881, and the space between the display cover 741 and the tank body 71 is opened through the drain valve 881. Water may flow into the inside of (740). In addition, the water flowing into the space 740 between the display cover 741 and the tank body 71 will flow into the inner space of the tank body 71 through the display opening 741c. You can.

The drain valve 881 is inserted into the inside of the tank body 71 and has a structure that opens and closes. However, the drain valve 881 may be covered by the display cover 741, so the drain valve 881 ) and exposure of the part where water flows into the water tank 70 can be prevented.

In this way, when the water tank 70 is fully inserted and installed, the front end of the valve opening member 881c is pressed from the inside of the water tank 70, and thus the drain valve 881 is opened. Water from the cultivation shelf 30 discharged through the drain pipe 89 may be recovered into the water tank 70. When the water tank 70 is closed, the front end of the valve opening member 881c is continuously pressed by the water tank 70, and thus the drain valve 881 remains closed.

In addition, when the water tank 70 is pulled out for water replenishment or injection of nutrient solution, the front end of the valve opening member 881c and the water tank 70 are spaced apart from each other, and the elastic force of the elastic member 881d As a result, the valve opening member 881c blocks the flow path inside the drain valve 881, and the drain valve 881 can be in a closed state.
