Hereinafter, the structure of the machine room 200 will be examined in more detail with reference to the drawings.

Figure 5 is a perspective view showing the structure of the machine room of the plant cultivation device.

As shown, the machine room module 20 is mounted on the lower surface of the cabinet 10 and forms a machine room 200 space that is independent from the cultivation space 100 below the cabinet 10. The machine room module 20 may be comprised of a machine room bottom plate 211 forming the lower surface, a pair of machine room side plates 212 forming both sides, and a machine room rear plate 213 forming the back.

The machine room bottom plate 211, the machine room side plate 212, and the machine room rear plate 213 are combined to form a single module, which can be called a machine room frame. The space formed by the machine room frame may be formed so that the top and front surfaces are open. Accordingly, the machine room frame is coupled to the lower surface of the cabinet 10 to form the machine room 200 below the cabinet 10.

Therefore, when the heat dissipation fan 233 is driven, external air is sucked in and flows into the left space of the machine room module 20 through the left side of the grill part 221, and the sucked air passes through the condenser 242. While doing so, heat is exchanged with the refrigerant inside the condenser 242 to dissipate heat in the condenser 242. Then, the air passing through the heat dissipation fan 233 cools the compressor 241 as it passes through it. Additionally, the air that has passed through the compressor 241 may be discharged forward through the right side of the grill portion 221.

That is, when the plant cultivation device 1 is installed, intake of external air and discharge of air inside the machine room module 20 occur from the front while passing through the front cover 22. Accordingly, the plant cultivation device 1 can be installed in a space where both the left and right sides and the rear are blocked. In particular, even if the plant cultivation device 1 is installed as a built-in piece of furniture such as a sink, cooling and heat exchange of the compressor 241 and the condenser 242 inside the machine room module 20 can be effectively achieved.

It is shielded to prevent it.

In addition, a water supply pipe fixing part may be further formed on the guide cover 122b. The water supply pipe fixing part fixes the end of the water supply pipe 84 through which water is discharged to be positioned on the water supply portion 316 of the upper cultivation shelf 30a and the lower cultivation shelf 30b, respectively. Accordingly, the position of the outlet of the water supply pipe 84 can be fixed, and water can be supplied to the cultivation shelf 30 at an accurate position.

The water supply pipe 84 may be formed in the shape of a metal tube, and includes an upper water supply pipe 84a connected to the upper pump 83a to supply water to the upper cultivation shelf 30a, and the lower pump 83b. It may include a lower water supply pipe (84b) that is connected to and supplies water to the lower cultivation shelf (30b).

It may be called a water supply module, including the sub tank 82, a pump 83, and a water supply pipe 84 arranged to supply water to the cultivation shelf 30, and the water supply module is provided by the pump cover 81. It is provided on the inner space and the side wall of the cultivation space 100 so that it is not exposed to the outside during normal use.

In particular, the water supply pipe 84 is accommodated in the water supply pipe guide portion 122a formed on the side of the cultivation space 100, and is not exposed to the outside by the guide portion cover 122b. Additionally, the end of the water supply pipe 84 adjacent to the cultivation shelf 30 may be covered by the cover plate 53 of the blower 50.

Additionally, a drainage module may be placed on one side of the cultivation space 100 where the water supply module is placed and on the other side facing the other side. That is, the water supply module and the drainage module may be disposed on both left and right sides of the cultivation shelf 30, respectively.

The drain pipe 89 extends in the vertical direction and allows all water drained from the upper and lower cultivation shelves 30a and 30b disposed vertically to be drained through one drain pipe 89. When a plurality of cultivation shelves 30 are provided, the drain pipe 89 may be arranged to pass through a plurality of cultivation shelves 30.

Meanwhile, when the drain pipe 89 is mounted on the drain pipe guide portion 122c, the drain pipe 89 does not protrude into the cultivation space. Accordingly, it is possible to prevent the drain pipe 89 from interfering with the cultivation shelf 30 even when the cultivation shelf 30 is taken in or out. In addition, the drain pipe 89 is connected to the drain tray 85 while disposed inside the drain pipe guide portion 122c to allow water drained from the cultivation shelf 30 to flow inside the pump cover 81.

Hereinafter, the structure of the water tank 70 will be examined in detail with reference to the drawings.

Figure 9 is a perspective view of the water tank according to an embodiment of the present invention as seen from above. And, Figure 10 is a perspective view of the water tank viewed from below.

As shown in the figure, the water tank 70 includes a tank body 71 that stores water supplied to the cultivation shelf 30 and water drained from the cultivation shelf 30, and the tank body ( It may include a tank cover 72 that opens and closes the open upper surface of 71).

A tank handle 711 that the user can hold may be formed on the front of the tank body 71 to withdraw and withdraw the water tank 70, and the tank rails 79 may be provided on both left and right sides of the tank body 71. ) A rail mounting portion 73 that is coupled may be formed. Accordingly, the water tank 70 can be mounted inside the cultivation space 100 to be retractable.

Cover connection portions 712 on which cover rotation axes 721 protruding from both sides of the rear end of the tank cover 72 are mounted may be formed on both left and right rear ends of the tank body 71. Accordingly, the tank cover 72 can be rotated based on the cover rotation axis 721, and the open upper surface of the tank body 71 can be accessed by rotation of the tank cover 72. Accordingly, water can be replenished by opening the tank cover 72 while the water tank 70 is in and out. In addition, it may be possible to adjust the concentration of water, that is, the culture medium, inside the water tank 70 by opening the tank cover 72 to introduce nutrients necessary for plant growth.

Meanwhile, a valve insertion hole 744a may be formed in the rear 744 of the tank body 71. The valve insertion hole 744a may be located at a position corresponding to the drain valve 881, and may be formed in a size that allows the drain valve 881 to be inserted. The valve insertion hole 744a can be called a valve inlet because the drain valve 881 is inserted therein.

When the water tank 70 is introduced, the drain valve 881 may be inserted into the valve insertion hole 744a and may be configured to open inside the tank water level detection unit 744a. Accordingly, water drained through the drain pipe 89 may flow into the water tank 70 through the drain valve 881.

Additionally, a tank outlet 751 may be formed at the rear of the tank body 71. The tank outlet portion 751 is a portion through which water supplied to the cultivation shelf 30 is discharged from the inside of the water tank 70, and is formed in a tube shape protruding backward from the rear of the tank body 71. You can.

The tank outlet portion 751 may be inserted into the fitting portion 811 exposed to the front of the pump cover 81 when the water tank 70 is inserted. The fitting part 811 may be in communication with the sub tank 82, and the sub tank 82 may be connected to the pump 83. Accordingly, water discharged through the tank outlet 751 can be supplied to the cultivation shelf 30 through the sub tank 82, pump 83, and water supply pipe 84.

Additionally, the tank sensing member 752 may be provided at the rear of the tank body 71. The tank sensing member 752 may be located at a position facing the tank sensing device provided inside the pump cover 81 and may be configured to detect whether the water tank 70 is introduced.

In a state where the water tank 70 is not completely retracted, drainage and water supply operations are not smooth, and in particular, the drained water leaks and is discharged inside the cultivation space 100 rather than the water tank 70, thereby causing the cultivation space ( 100) may contaminate. Accordingly, it is possible to detect whether the water tank 70 is completely retracted and control the driving of the driving device 86 and the pump 83 according to the detection state. Additionally, if the water tank 70 is not retracted, this may be notified through the display 14.

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 11 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 12 is a perspective view of the water supply module and drainage module. And, Figure 13 is a diagram showing the water flow state between the cultivation shelf and the water tank.

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. Also, 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, as shown in FIG. 13, it may have a structure that allows water to circulate between the water tank 70 and the cultivation shelf 30.

Hereinafter, the structure of the drain tray 85 will be examined in more detail with reference to the drawings. The drain tray 85 may be provided with an upper drain tray 85a and a lower drain tray 85b, respectively, and the upper drain tray 85a and the lower drain tray 85b may have completely the same shape. Therefore, hereinafter, the upper drain tray 85a and the lower drain tray 85b will be described without distinction.

Figure 14 is a perspective view of a drainage tray according to an embodiment of the present invention.

As shown in the drawing, the drainage tray 85 may include a plate-shaped tray bottom surface 851 and a tray peripheral portion 852 extending upward along the circumference of the tray bottom surface 851. .

The bottom surface of the tray 851 may be configured to form an area that can include at least the drain portion 318 and the drain hole 319a of the cultivation shelf 30 and the drain guide pipe 87. That is, it can be formed to have a predetermined area so that water draining from the drain portion 318 and the drain hole 319a is directed toward the drain guide pipe 87. In addition, the bottom surface of the tray 851 is inclined so that water discharged from the cultivation shelf 30 can flow more smoothly toward the drainage guide pipe 87. In addition, the tray peripheral portion 852 can prevent water flowing along the drain tray 85 from overflowing.

In addition, a portion of the front portion of the tray peripheral portion 852 adjacent to the rear end of the cultivation shelf 30 may be formed with a tray cut portion 853 cut downward. The tray cutout 853 may be formed to extend upward and lower than the height of the tray peripheral portion 852, and may be formed across the front end of the drainage tray 85 and a portion of the right end in contact with the front end. Therefore, it is possible to prevent interference between the lower surface of the cultivation shelf 30 and the drainage tray 85 during the process of loading and unloading the cultivation shelf 30.

Meanwhile, an overflow prevention portion 854 may be formed on the tray bottom surface 851 corresponding to the tray cutout 853. The overflow prevention portion 854 protrudes from the bottom surface of the tray 851 and is formed along the front and side edges of the drain tray 85, but is formed at a position somewhat spaced from the outer end of the drain tray 85. It can be. The overflow prevention portion 854 may be formed in plural numbers and may be spaced apart from each other in the front-back direction. Therefore, even if the plant cultivation device 1 is shaken by vibration, water drained along the drain tray 85 can be prevented from flowing forward and overflowing through the tray cutout 853.

Additionally, the bottom surface of the tray 851 may be formed to be higher at the portion where the overflow prevention portion 854 is disposed and gradually lower toward the portion where the tray drain portion 856 is formed. Therefore, it is possible to prevent water from overflowing from the drain tray 85 and to ensure smooth drainage from the drain tray 85.

Meanwhile, a tray mounting portion 855 may be formed on the lower left end of the tray bottom surface 851, and a screw hole 855a may be formed on the upper surface of the tray mounting portion 855. The screw 855b may pass through the screw hole 855a and may be fastened to the tray bracket 859 mounted on the tray mounting unit 855. In addition, a screw hole 859a into which the screw 855b is fastened may be further formed in the tray bracket 859. If necessary, the tray mounting portion 855 may be coupled to components below the drainage tray 85, such as the lighting device 40, instead of the tray bracket 859.

A tray drain portion 856 protruding outward may be formed at the left and rear corners of the drain tray 85. The tray drain portion 856 may protrude to the outside of the drain tray 85 and be inserted into the drain guide pipe 87. In addition, the tray peripheral portion 852 may be formed to extend along the circumference of the tray drain portion 856, so that water guided to the tray drain portion 856 does not overflow and flows through the drain guide pipe 87. It can be directed inward.

Additionally, the tray drain 856 extends downward so that all water flowing into the tray drain 856 flows into the drain guide pipe 87 without leaking or splashing to the outside. Additionally, the tray drain hole 856a may be opened at the extended lower end of the tray drain portion 856.

Hereinafter, the drain pipe 89 will be examined in more detail with reference to the drawings.

Figure 15 is an exploded perspective view of a drain pipe according to an embodiment of the present invention. And, Figure 16 is an exploded perspective view of the drain guide pipe constituting the drain pipe.

As shown in the drawing, the drain pipe 89 consists of a drain guide pipe 87 connected to the drain tray 85 and a drain pipe 87 connected to the water tank 70. It may include a tube (88).

In detail, the drain guide pipe 87 guides the water supplied from the drain tray 85 downward, and has a predetermined length so that a large amount of water flowing in from the drain tray 85 can be guided downward without overflowing. It may be formed in a tubular shape with a cross-sectional area.

At this time, the drain pipe guide portion 122c on which the drain guide pipe 87 is mounted may be formed by bending the side plate 122, and may have a square cross-sectional area. Therefore, it would be preferable that the drain guide pipe 87 be formed to have a square cross-section that can be inserted into the drain pipe guide portion 122c.

In addition, the drainage guide pipe 87 has a structure connected to a plurality of drainage trays 85 that guide water drained from the plurality of cultivation shelves 30 when a plurality of cultivation shelves 30 are arranged vertically. You can have it. Accordingly, the upper end of the drainage guide pipe 87 may extend at least to a position corresponding to the position of the cultivation shelf 30 located at the uppermost position, and the lower end of the drainage guide pipe 87 may be at the lowermost position. It may be located lower than the cultivation shelf 30 is positioned.

As an example, the cultivation shelf 30 may be composed of two upper cultivation shelves 30a and lower cultivation shelves 30b, and the drainage tray 85 also includes an upper drainage tray 85a and a lower drainage tray 85b. may be provided, respectively. In addition, the drain guide pipe 87 may include an upper drain guide pipe 871 connected to the upper drain tray 85a and a lower drain guide pipe 872 connected to the lower drain tray 85b. .

The upper drainage guide pipe 871 may extend long in the vertical direction and may extend in a straight line from the upper cultivation shelf 30a to the lower cultivation shelf 30b. Additionally, an upper opening 871a may be formed on the upper surface of the upper drain guide pipe 871. The upper opening 871A is opened to allow the tray drainage portion 856 of the upper cultivation shelf 30a to be inserted, and may therefore be called an upper inlet. The area of the upper opening 871a may correspond to the cross-sectional area of the drain guide pipe 87, and may be formed to allow a large amount of water to flow in at once.

Meanwhile, a guide pipe protrusion 873 may be formed in the upper drain guide pipe 871 protruding inside the upper drain guide pipe 871. The guide pipe protrusion 873 causes water draining along the upper drain guide pipe 871 to collide as it falls, and at least one or more of the guide pipe protrusions 873 are formed along the vertical extension direction of the upper drain guide pipe 871. You can.

Water draining along the upper drain guide pipe 871 can be hit by the guide pipe protrusion 873, and the speed of the water draining downward can be adjusted and the falling distance of the water can be divided into multiple times. Therefore, it is possible to prevent noise generated when water falling through the drain guide pipe 87 falls from the top to the bottom of the drain guide pipe 87 at once. In addition, the flow rate of water flowing downward along the inner wall of the upper drain guide pipe 871 can be adjusted by the guide pipe protrusion 873 to minimize the sound of water rippling.

A plurality of guide pipe protrusions 873 may be formed along the length of the upper drain guide pipe 871, and one guide pipe protrusion 873 may be formed at the upper and lower portions of the upper drain guide pipe 871.

The inner surface of the upper drain guide pipe 871 corresponding to the guide pipe protrusion 873 may be depressed, and the upper drain pipe guide portion 122c corresponding to the depressed outer surface of the guide pipe protrusion 873 A guide tube mounting portion 873a may be formed on one side (right side in FIGS. 15 and 16). The guide pipe mounting portion 873a may be formed in the flat shape and may be in close contact with the inner surface of the drain pipe guide portion 122c. In addition, a screw hole 873b may be formed in the guide pipe mounting portion 873a, and a screw penetrating the screw hole 873b is fastened to the side wall of the drain pipe guide portion 122c to form the drain guide pipe ( 87) can be maintained in a fixed state inside the drain pipe guide portion 122c.

A guide pipe insertion portion 874 may be formed at the lower end of the upper drain guide pipe 871. The lower end of the guide pipe insertion portion 874 is open so that water flowing along the upper drain guide pipe 871 can be discharged downward. Additionally, the guide tube insertion portion 874 may be formed to have a smaller cross-sectional area as it goes downward. That is, the outer surface of the guide tube insertion portion 874 may be inclined or stepped, and may be inserted into the lower opening 872a of the lower drain guide tube 872.

Meanwhile, the lower drain guide pipe 872 may be formed in a bent shape to correspond to the lower shape of the drain pipe guide portion 122c. In detail, the lower drain guide pipe 872 is connected to the upper drain guide pipe 871, has a guide pipe vertical portion 872c extending in the vertical direction, and extends forward from the bottom of the guide pipe vertical portion 872c. It may include a horizontal portion 872d of the guide pipe.

The lower drain guide pipe 872 has an open upper surface and may form the lower opening 872a. In addition, the upper end of the lower drain guide tube 872 where the lower opening 872a is formed may be formed with a guide tube receiving part 877 into which the guide tube insertion part 874 is inserted. The guide tube receiving portion 877 may be formed to have a larger cross-sectional area than the guide tube insertion portion 874 and may be formed to have a size corresponding to the upper opening 871a. Therefore, when the upper drain guide pipe 871 and the lower drain guide pipe 872 are coupled to each other, they can be formed to have a sense of unity.

Additionally, a side opening 876 may be formed below the guide tube receiving portion 877, that is, in the guide tube vertical portion 872c. The side opening 876 is opened to allow the tray drain portion 856 of the lower drain tray 85b to be inserted, and may therefore be called a lower inlet. In addition, the side opening 876 is located at a position away from the bottom of the guide pipe vertical portion 872c, so that water easily flows in through the tray drain portion 856 of the lower drain tray 85b. It can be guided forward.

Meanwhile, the guide pipe horizontal portion 872d extends forward and may extend to the front end of the drain pipe guide portion 122c. Additionally, a tube connection portion 875 may be formed to protrude at the front end of the guide tube horizontal portion 872d, and the drain tube 88 may be connected to the tube connection portion 875. At this time, the tube connection portion 875 may be located inside the space shielded by the pump cover 81. Accordingly, the drain tube 88 is connected to the drain guide pipe 87 inside the pump cover 81 and may extend to the valve insertion hole 744a of the water tank 70.

The drain tube 88 may be composed of a flexible tube, so it is easy to bend into the inner (rear) space of the pump cover 81 and is effectively disposed inside the pump cover 81, which has a complex interior. It can be.

Additionally, a drain valve 881 may be provided at the end of the drain tube 88. The drain valve 881 may be located at a position facing the valve insertion hole 744a, may be fixed to the front of the pump cover 81, and may also protrude toward the water tank 70.

Hereinafter, the connection structure and water supply state of the drain tray 85 and the drain guide pipe 87 will be examined in more detail with reference to the drawings.

Figure 17 is a partial perspective view showing the state of water supply from the upper drain tray to the drain guide pipe according to an embodiment of the present invention.

As shown, the opening and closing member 36 of the cultivation shelf 30 is opened, or the water of the cultivation shelf 30 flows into the drainage tray 85 through the drain portion 318 of the cultivation shelf 30. may fall. At this time, the drain tray 85 is disposed vertically below the drain hole 319a and the drain portion 318, and is located adjacent to it, so that it can stably receive water discharged from the cultivation shelf 30.

In addition, the water flowing into the drain tray 85 flows toward the tray drain part 856 along the slope of the tray bottom surface 851, and flows through the tray drain hole 856a to the drain guide pipe 87. ) may flow into the inside.

At this time, as shown in FIG. 17, the tray drain portion 856 of the upper drain tray 85a may be inserted into the upper surface opening 871a formed at the top of the upper drain guide pipe 871. That is, the tray drain portion 856 of the upper drain tray 85a protrudes laterally from above the upper drain guide pipe 871, and the extended lower end is the upper surface opening 871a of the upper drain guide pipe 871. ) can be inserted into the inside of the

Accordingly, water discharged through the tray drain hole 856a of the upper drain tray 85a may flow into the upper drain guide pipe 871. Meanwhile, the upper surface opening 871a of the upper drain guide pipe 871 is sized to accommodate the upper drain tray 85a, and can be significantly larger than the size of the tray drain hole 856a. . Therefore, even when a large amount of water flows in through the upper drain tray 85a, the water does not flow back through the upper surface opening 871a and is smoothly discharged downward through the upper drain guide pipe 871.

Water flowing into the upper drain guide pipe 871 falls downward, and some of the falling water may collide with the guide pipe protrusion 873. At this time, the guide tube protrusion 873 formed at the uppermost position among the guide tube protrusions 873 is disposed at a position adjacent to the tray drain 856 and may be arranged to face the tray drain 856a. there is.

Accordingly, water falling from the tray drain 856a may collide with the guide tube protrusion 873 and then fall downward. When water falls while hitting a plurality of guide pipe protrusions 873, noise generated when water drops fall directly from the top of the drain guide pipe 87 to the bottom of the drain guide pipe 87 can be prevented, and the drain The sound of water rippling along the wall of the guide pipe 87 can also be prevented.

In this way, water flowing into the upper drain guide pipe 871 through the upper drain tray 85a flows downward, and passes through the lower drain guide pipe 872 and the drain tube 88 to the water tank 70. may flow into.

Figure 18 is a cut-away perspective view showing the state of water supply from the lower drain tray to the drain guide pipe according to an embodiment of the present invention.

As shown, the guide tube insertion portion 874 formed at the lower end of the upper drain guide tube 871 is inserted through the opened upper surface of the lower drain guide tube 872, and the upper drain guide tube 871 and the lower drain guide pipe 872 may be in communication with each other. Therefore, the water drained along the upper drain guide pipe 871 flows into the lower drain guide pipe 872, and joins the water flowing in through the lower drain tray 85b to form the drain tube 88. ) is directed to.

Therefore, the drain guide pipe 87 can provide a flow path with a cross-sectional area of sufficient size so that water simultaneously discharged through at least the upper drain tray 85a and the lower drain tray 85b can be effectively discharged without backflow. there is.

Meanwhile, water drained from the lower cultivation shelf (30b) can be collected in the lower drainage tray (85b), and water in the lower drainage tray (85b) is discharged from the tray bottom surface 851 to the tray drain ( 856) and may flow into the lower drain guide pipe 872 through the tray drain hole 856a.

At this time, the tray drain portion 856 of the lower drain tray 85b may protrude laterally and may be inserted into the side opening 876 opened on the side of the lower drain guide pipe 872. Accordingly, the tray drain 856 is inserted into the lower drain guide pipe 872 through the side opening 876, and the extended lower end of the tray drain 856 is inserted into the side opening 876. and is locked so that the lower drain tray 85b and the lower drain guide pipe 872 maintain a coupled relationship with each other. and. The tray drain hole 856a is opened downward from the inside of the lower drain guide pipe 872 to allow all water drained from the lower drain tray 85b to flow into the lower drain guide pipe 872.

In addition, the water discharged through the tray drain hole 856a of the lower drain tray 85b is changed along with the water flowing through the upper drain guide pipe 871 and flows forward along the guide pipe horizontal portion 872d. flows and may flow into the drain tube 88 connected to the lower drain guide pipe 872.

The drain tube 88 is located inside the cultivation space 100 on the side wall of the cultivation space 100, more specifically, the pump z cover 81 where the pump 83 and the sub tank 82 are disposed. It can extend into the rear space of. In addition, the drain valve 881 disposed at the end of the drain tube 88 is connected to the water tank 70 so that water discharged through the drain pipe 89 can be directed to the water tank 70. there is.

Figure 19 is a cut-away perspective view showing the connection between the water tank and the drain valve.

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.

In addition, the valve opening member 881c may be supported by an elastic member 881ㅇ inside the combined interior of 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 water level display portion 741 may be formed at a portion where the front end of the drain valve 881 is inserted. The water level display unit 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 water level display unit 741 may extend from the bottom of the tank body 71 to the top of the tank body 71. Additionally, a display opening 741a cut in the vertical direction may be formed in the water level display portion 741. Water inside the tank body 71 may flow into the space spaced between the water level display unit 741 and the tank body 71 through the display opening 741a.

Additionally, an indicator floater 742 may be formed in the space between the water level indicator 741 and the tank body 71. The display floater 742 may be made of a foam material that floats on water and may have an identifiable color. Accordingly, the display 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 intuitively displayed through the display portion opening 741a.

Additionally, the display 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 water level display portion 741. The tank water level detection device 743 can detect the water level of the water tank 70 by detecting a change in the magnetic field of the magnet of the display 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 water level display unit 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 water level indicator 741 and the tank body 71 is created through the drain valve 881. Water may flow into the inside of (740). In addition, the water flowing into the space 740 between the water level indicator 741 and the tank body 71 will flow into the inner space of the tank body 71 through the indicator opening 741a. 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 obscured by the water level indicator 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. When the drain valve 881 is closed, drainage is not performed through the drain pipe 89. Accordingly, water drained from the drain pipe 89 is prevented from leaking into the cultivation space 100.

In addition, although not shown in detail, the state of the water tank 70 being drawn in and out of the water tank 70 may be detected by a sensing device that detects the incoming and outgoing state of the water tank 70 . In addition, the control unit that controls the operation of the plant cultivation device 1 restricts the operation of the driving device 86 when the water tank 70 is withdrawn to prevent water from the cultivation shelf 30 from draining. Alternatively, the operation of the pump 83 may be stopped to prevent water supply to the cultivation shelf 30.

Hereinafter, the structure of the cultivation shelf 30 will be examined in more detail with reference to the drawings.

The length of the lower rod 862c and the downward movement stroke of the rod 862 may be set to a level such that the opening and closing member 36 can be rotated to sufficiently open the drain hole 319a.

As an example, the rod 862 may be moved downward by a set distance when the driving device 86 is operated to drain the cultivation shelf 30, and the opening and closing member ( 36) can be rotated. Then, the drain hole 319a is opened by rotation of the opening and closing member 36 to drain water from the cultivation shelf 30.

And, when the cultivation shelf 30 is not drained, the driving device 86 is not operated, and the rod 862 is located inside the driving device case 861 or the lower rod. The lower end of 862 is positioned at the lower end of the driving device case 861. Accordingly, it is possible to prevent the rod 862 from being exposed to the outside and to prevent it from interfering with components inside the cultivation space 100.

Hereinafter, the operating states of the driving device 86 and the opening and closing member 36 will be examined in more detail with reference to the drawings.

Figure 30 is a diagram showing a closed state of the opening and closing member before operation of the driving device.

As shown in the drawing, water inside the water tank 70 is supplied to the cultivation shelf 30 through the water supply pipe 84 by driving the pump 83 for cultivating plants. It can be supplied in a set amount. Additionally, the cultivation shelf 30 may be filled with water at a set level.

While water is supplied to the cultivation shelf 30 and until drainage begins after water supply is completed, the driving device 86 is not operated, and the opening and closing member 36 also shields the drain hole 319a. will be maintained. Accordingly, the cultivation shelf 30 can be maintained filled with water, and a necessary amount of water can be absorbed into the seed package 90. At this time, the water in the cultivation shelf 30 is supplied from the water tank 70 and may be a culture medium containing nutrients necessary for plant growth. Of course, if the seed package 90 itself contains nutrients, it may be possible to supply only pure water from the water tank 70.

In an initial state in which the driving device 86 is not operated, most of the rod 862 may be located inside the driving device case 861. Therefore, when viewed from the front, the driving device 86 and the rod 862 may be hidden by the blower 50 and may be configured so that they are not substantially exposed. In addition, the lower end of the rod 862 may protrude downward from the lower surface of the driving device case 861, but may remain separated from the opening and closing member 36 and may be obscured by the blower 50. It would be desirable to protrude just enough.

When no external force is applied to the opening and closing member 36 by the driving device 86, the opening and closing member 36 can remain closed. When the opening and closing member 36 is closed, the inner surface of the opening and closing member 36 may surround and accommodate the shelf drain portion 319.

At this time, the sealing member 363 may be in close contact with the shelf drain portion 319 to shield it. In addition, the opening and closing member 36 can be pressed and maintained in a closed state by the elastic force provided by the elastic member 364, and the sealing member 363 is connected to the shelf drain (319a) to shield the drain hole (319a). 319) can be pressed and adhered to the outer surface.

Accordingly, the water supplied inside the cultivation shelf 30 does not drain into the drainage tray 85 under normal water supply conditions, but maintains a set water level or maintains a state in which water can be supplied to the seed package 90. . Additionally, the drain tray 85 may remain empty.

Figure 31 is a diagram showing a state in which the opening and closing member is opened by the operation of the driving device.

As shown, if water is supplied to the seed package 90 sufficiently after a set time while water is supplied to the cultivation shelf 30, the water inside the cultivation shelf 30 can be drained.

In order to drain water from the cultivation shelf 30, the driving device 86 is first operated. In detail, the pinion 864 may be rotated by forward rotation of the drive motor 863, and the rod 862 coupled to the pinion 864 may be rotated downward.

At this time, the rod 862 is located vertically above the rotation operation unit 362 of the opening and closing member 36, and when the rod 862 continues to move downward, the rotation operation unit 362 is pressed to close the opening and closing member 36. rotates. The rod 862 is moved to a height that is at least lower than the initial height of the rotation operation unit 362, and the opening and closing member 36 is lowered to a height where it can be rotated to sufficiently open the drain hole 319a. . When the rod 862 descends to the set height, the drive motor 863 stops rotating.

When the rotation operation unit 362 is pressed due to the lowering of the rod 862, the opening and closing member 36 rotates based on the opening and closing member rotation axis 319b. The opening and closing member 36 is rotated counterclockwise (as seen in FIG. 31), and when the opening and closing member 36 is rotated more than a set angle, the sealing member 363 opens the drain hole 319a.

In addition, while the opening and closing member 36 rotates counterclockwise for opening, the elastic member 364 may be elastically deformed, and the opening and closing member 36 may return to the initial position as shown in FIG. 30. It can be in a state of elasticity.

When the drain hole 319a is opened by rotating the opening and closing member 36, water inside the cultivation shelf 30 can be drained through the drain hole 319a and into the inside of the drain tray 85. fall down.

In addition, water that falls into the drain tray 85 may flow along the bottom surface of the tray 851, head to the tray drain part 856, and flow into the drain pipe 89. Water flowing into the drain pipe 89 can be recovered into the water tank 70 and stored so that it can be re-supplied to the cultivation shelf 30.

Meanwhile, when all the water stored inside the cultivation shelf 30 is discharged, the drive motor 863 can rotate in reverse, and the rod 862 moves upward to return to its initial state.

At the same time, the opening and closing member 36 is rotated clockwise by the elastic force provided by the elastic member 364, and the opening and closing member 36 can be in a closed state again. When the opening and closing member 36 is closed, the sealing member 363 can be in the state shown in FIG. 30, shielding the drain hole 319a again, and maintaining a state in which water can be supplied to the cultivation shelf 30. .

This water supply and drainage process can be repeated at set time intervals, and an appropriate amount of water can be supplied to plants grown on the cultivation shelf 30 at the right time. Although not explained in detail, light is supplied by the lighting device 40 during the repeated process of water supply and drainage, and the temperature of the cultivation space is controlled and airflow is formed by the temperature control device and the blower 50. This can be done.
