Depending on at least one of the position and the arrangement time, zoning control for each area, light amount control, wavelength band control, etc. may be performed using a plurality of lamps of the light source module 160 .

The light source module 160 may be provided with two substrates 162 according to an embodiment of the present invention, and the two substrates 162 are located on the left and right sides respectively with the sensor module 170 located in the center. However, the present invention is not particularly limited to the number or arrangement of the substrate 162 .

The modularized light source module 160 may be mounted on or detached from the upper portion of the inner case 130 in units of modules.

The substrate cover 161 may have a through-hole 161a formed at a position corresponding to the sensor module 170, and when the substrate cover 161 is coupled with the substrate base 163, the sensor module 170 forms the through-hole. By being inserted into (161a), the sensor module 170 can be exposed toward the cultivation space (S).

Accordingly, the substrate cover 161 does not cover the front of the sensor module 170, and the sensor module 170 is exposed toward the cultivation space S through the through hole 161a, so that the lamp by the substrate cover 161 It is desirable to prevent the sensor module 170 from being affected by light reflection or light refraction.

However, the outer circumferential surface of the sensor module 170 and the through hole 161a prevent moisture in the cultivation space S from flowing into the substrate 162 through the gap formed between the through hole 161a and the sensor module 170 inserted therein. ) It is preferable that a sealing member (not shown) is interposed between the light source module 160 to keep the inside of the light source module 160 airtight or watertight.

It is preferable that (G) is interposed so that heat generated from the light source module 160 provided on the ceiling of the inner case 130 located directly below does not affect another internal case 130 located directly above.

Since normal air has a thermal conductivity of 0.025 W/Mk, the air insulation layer (G) is interposed between two adjacent inner cases 130 to block heat generated from the light source module 160 directly below the inner case 130. It is possible to implement an independent plant cultivation environment for each cultivation space (S) provided by the.

The air insulation layer (G) may be provided on an outer upper surface of any one inner case 130, and at this time, a heat insulation member (G2) may be additionally provided to form a layer with the air insulation layer (G1). Here, the heat insulating member G2 is not particularly limited as long as it is a heat insulating member, but may be, for example, Styrofoam having a thermal conductivity of 0.035 W/Mk.

That is, as shown in FIG. 11, the air insulation layers Ga1 and Gb1 and the insulation members Ga2 and Gb2 may be sequentially stacked on the outer upper surface of the inner case 130, and the light source module 160 operates. The high-temperature air with the generated thermal energy stays in the air insulation layer (G), so that the thermal energy is not transferred to the upper inner case 130, and as will be described later, the inner case heat conduction plate 131 and the cabinet frame 101 , 102).

Preferably, the heat insulating member G2 provided on the upper part of the air insulating layer G1 may extend to cover at least one of the rear surface and left and right side surfaces in addition to the upper part of the inner case 130 . That is, it is preferable to implement an independent plant cultivation environment by blocking the internal cultivation space (S) of the inner box 130 from other components in the plant cultivation apparatus 100 by the heat insulating member (G2).

Meanwhile, FIG. 13 is a view showing an internal wound heat conduction plate according to an embodiment of the present invention.

As shown in FIG. 13 , according to one embodiment of the present invention, an inner wound heat conduction plate 131 prepared to be interviewed may be further included on an upper outer surface of the inner wound 130 .

The inner case heat conduction plate 131 is a substantially plate-shaped heat conductor, and the heat generated from the light source module 160 provided on the ceiling of the inner case 130 is dispersed through the inner case 130 and the inner case heat conduction plate 131 interviewed therewith. By doing so, it is possible to prevent the inner case 130 from being rapidly heated by the light source module 160 .

To this end, as described above, the inner case heat conduction plate 131 is seated so as to face the outer surface of the upper portion of the inner case 130, and a part is provided to come into contact with the cabinet frames 101 and 102, and the light source module 160 operates. The generated heat may be sequentially transferred and dispersed through the inner case 130, the inner case heat conduction plate 131, and the cabinet frames 101 and 102.

To this end, it is preferable that the inner case 130, the inner case heat conduction plate 131, and the cabinet frames 101 and 102, which provide a path through which heat is transferred, are heat conductors.

At this time, the inner wound heat conduction plate 131 is provided to face the upper outer surface of the first inner wound 130b, and the first and second heat conduction pieces 131a and 131b extending upwards on the left and right sides are the second horizontal frame 102 ) can be coupled to contact.

As a result, the second inner case 130a and the inner case heat conduction plate 131 of the first inner case 130b are all coupled to the second horizontal frame 102, so assembling the inner case heat conduction plate 131 can be simplified. At this time, as shown in the drawing, the left and right lower portions of the second inner case 130a may be coupled to the second horizontal frame 102 .

In this way, since the first and second heat conduction pieces 131a and 131b provided at the left and right ends of the inner upper heat conduction plate 131 extend upward, the above-described air insulation layer G is provided to face each other for first and second heat conduction. It may be provided between the pieces 131a and 131b.

Accordingly, the high-temperature air with thermal energy generated by the operation of the light source module 160 stays in the air insulation layer (G), but passes through the inner upper heat conduction plate 131 and the cabinet frames 101 and 102 sequentially. Heat can be dissipated along the

That is, the air insulation layers Ga1 and Gb1 and/or the heat insulation members Ga2 and Gb2 allow heat generated from the light source module 160 of the inner case 130 located at the bottom to affect another inner case 130 located at the top. At the same time, the substrate base 163 disperses the heat transmitted to the inner case 130 by the operation of the light source module 160 to the surroundings, especially the cabinet frames 101 and 102, so that the inner case 130 It can prevent rapid heating.

Returning again, the sensor module 170 of the light source module 160 may be a module that senses (recognizes) the capsules 200 randomly disposed in a plurality of spots of the tray 120 and generates control data. Here, the control data may include information about the number of capsules 200 randomly disposed in a plurality of spots of the tray 120, a variety, a position and a time of arrangement.

Also, as another example, when light of a specific wavelength band emitted from a recognition unit of the capsule 200 is used as a recognition method of the capsule 200, the sensor module 170 may be provided in the form of a light detection sensor.

In addition to this, various methods may be used as a method for recognizing the capsule 200, and in this case, various sensors matching the method for recognizing the capsule 200 may be used as the sensor module 170.

Meanwhile, the sensor module 170 may be turned on/off according to a user's selection. That is, the user completes setting the capsules 200 in a plurality of spots of the tray 200 and then turns on the sensor module 170, thereby setting the capsules at the time when the sensor module 170 starts operating ( 200), the environment of the cultivation space (S) can be automatically controlled according to the acquired control data.

As described above, the sensor module 170 may be disposed on the ceiling surface of the cultivation space (S). In this case, the sensor module 170 is provided along with a plurality of lamps on the substrate 162 of the light source module 160, and may be positioned approximately at the center. When a camera module or the like is used as the sensor module 170, the angle of view (scanning range) of the camera module covers all of the plurality of spots on the tray 120, thereby recognizing all of the capsules 200 arbitrarily disposed in the plurality of spots. It is desirable to be able to do so.

However, it is not limited to this, and the sensor module 170 may be provided at a location other than the ceiling surface within the cultivation space (S). For example, the sensor module 170 may be disposed on the tray 120 .

Meanwhile, FIG. 14 is a longitudinal cross-sectional view of the inner case according to another embodiment of the present invention, FIG. 15 is an exploded view of the drain tray of FIG. 14, and FIG. 16 is a view showing the drain tray of FIG. 15 in combination. .

As shown in FIGS. 14 to 16 , the inner case 130 according to an embodiment of the present invention may have a drain hole 1321 for discharging water stored on the inner bottom surface 1303 to the outside.

As described above, the tray 120 is provided at the bottom of the inner case 130, and the culture solution stored in the culture medium tank is provided to the inner accommodation space of the tray 120 through the water supply pipe 190 by a pump or an actuator. .

Since the water supply pipe 190 is connected to the tray 120 or the distal end of the water supply pipe 190 is drawn into the inside of the tray 120, and the culture medium is provided to the inner accommodation space of the tray 120, the normal tray 120 Water (or culture medium) does not accumulate on the inner bottom surface 1303.

However, when the tray 120 is drawn into or withdrawn from the inner box 130, the water in the tray 120 overflows as the tray 120 tilts, the culture medium in the tray 120 is overfilled, or the tray 120 Water is stored on the bottom surface 1303 of the inner case 130 when the water level sensor malfunctions or the culture solution supplied through the water supply pipe 190 is not guided to the inside of the tray 120 due to poor connection of the tray 120. there is

In addition to this, when a humid atmosphere is formed in the cultivation space S, condensed water may be generated, and even when a large amount of condensed water is generated, there is a problem in that water is stored on the bottom surface 1303 of the inner bed 130.

Accordingly, the inner case 130 according to an embodiment of the present invention preferably includes a drain 1321 to discharge water stored in the bottom surface 1303 to the outside of the inner case 130 .

At least one drain hole 1321 according to an embodiment of the present invention may be provided for each inner case 130. For example, the drain hole 1321 corresponds to the inner case 130 in a one-to-one correspondence, so that one inner case 130 has One drain 1321 may be provided.

The drain hole 1321 is preferably located on the bottom surface of the inner casing 130, preferably at the inner rear of the inner casing 130, more preferably adjacent to the water supply pipe 190 corresponding to the position of the water supply pipe 190. This is because, when a leak occurs in the culture medium supply through the water supply pipe 190, a relatively large amount of the culture medium leaks, and in this case, there is a need to quickly discharge the culture medium through the drain 1321.

At this time, in order to guide the water stored on the bottom surface of the inner case 130 to the drain hole 1321, at least a part of the bottom surface of the inner case 130 is preferably inclined downward with the location of the drain hole 1321 as the center.

On the other hand, the tray 120 has an opening so that the water contained in the tray 120 can be discharged to the outside of the tray 120 when the culture medium is supercharged therein or tilted when the tray 120 is drawn in and out. (1211).

The opening 1211 is formed at a predetermined height on one side of the tray 120, so that when water is accommodated in the tray 120 at a predetermined height or higher, it can be discharged to the outside through the opening 1211. That is, the opening 1211 may serve to keep the water level in the tray 120 constant.

At this time, the opening 1211 is preferably formed on the rear surface of the tray 120 so that water discharged to the outside through the opening 1211 can be easily guided to the outside of the inner case 130 through the drain hole 1321.

Also more preferably, the water supply pipe 190 for supplying the culture medium to the inside of the tray 120 is provided to the opening 1211 so that the culture medium stored in the culture tank is supplied to the inside of the tray 120 through the opening 1211. insertion can be combined.

Meanwhile, as shown in FIG. 14 , the inner box 130 according to an embodiment of the present invention preferably has a ceiling surface 1301 inclined downward toward the rear.

As the ceiling surface 1301 of the inner case 130 slopes downward toward the rear, condensate formed on the ceiling surface 1301 when the inside of the inner case 130 is in a humid atmosphere flows along the inclined ceiling surface 1301. It can be guided backward, and the condensed water guided backward can fall or flow along the rear inner wall 1302 and be guided to the drain hole 1321.

Specifically, FIG. 14 is a longitudinal cross-sectional view of the internal wound 130 according to an embodiment of the present invention when the internal wound 130 is cut based on a vertical cut plane placed in the front-back direction, wherein θ ₁ is less than 90°, for example. It may be 87°, θ ₂ may be greater than 90°, for example 93°, and θ ₃ may be greater than 90° such that the bottom surface 1303 is inclined, for example 91°.

The bottom surface 1303 of the inner case 130 also slopes downward toward the rear, so that water stored on the bottom surface 1303 of the inner case 130 may be guided to the drain 1321 .

On the other hand, in the drain hole 1321 formed on the bottom surface of the inner case 130 according to an embodiment of the present invention, a drain pipe ( 1325) may be included.

That is, water stored on the bottom of the inner case 130 may be discharged to the outside of the inner case 130 through the drain hole 1321 and the drain pipe 1325 .

At this time, the drain cap 1329 may cover the distal end of the drain pipe 1325 to block the drain pipe 1325 so that the distal end of the drain pipe 1325 has airtightness. 17 is a view showing the drain pipe 1325 and the drain cap 1329.

The drain cap 1329 may be an elastic member having elasticity such as rubber or silicon, and in this case, the drain cap 1329 may have an incision f cut to form a slit-shaped gap ( See Figure 17(b)). Accordingly, depending on whether an external force is applied to the drain cap 1329, the gap of the cutout f may be expanded or reduced.

According to one embodiment of the present invention, the incision (f) when water is discharged from the inner case 130 to the outside through the drain pipe 1325 is expanded as shown in FIG. 17 (c), but differently When the water is not discharged to the outside, the cutout (f) is made of only a very narrow gap, as shown in FIG.

That is, it is preferable that the drain cap 1329 drains only water through the drain pipe 1325 so that air in the flow path is not mixed when the drained culture medium circulates along the flow path.

On the other hand, in order to form the drain hole 1321 on the bottom surface of the inner case 130, according to an embodiment of the present invention, the drain hole 1321 and at least one inclined surface 1322 to 1324 inclined downward toward the drain hole 1321 The drain tray 132 having a can be attached to or detached from the bottom of the inner bed 130, and the drain tray 132 extends downward from the drain hole 1321 in addition to the drain 1321 and the inclined surfaces 1322 to 1324. A formed drain pipe 1325 may be further included.
