The liquid flow path 21a is open upward. The liquid flow path 21a extends in the width direction X of the flow path forming material 21. The other end of the liquid flow path 21a is closed by the end wall 24, and one end opens to the outside of the flow path forming material 21 at a position higher than the weir portion 25. Hereinafter, among the ends of the flow path forming material 21 in the width direction X, the end that is open to the outside will be referred to as an open end 21b. The weir portion 25 is provided below the open end 21b. The weir portion 25 stores the fluid flowing through the liquid flow path 21a in the liquid flow path 21a up to the height of the weir portion 25. The flow path forming member 21 is configured so that the liquid flows in the liquid flow path 21a toward the opening end 21b. The liquid is, for example, water. In other words, the flow path forming member 21 is configured so that a certain amount of liquid is stored by the weir portion 25, and the liquid can be discharged from the opening end 21b above the weir portion 25.

[0033] The flow path member 20 is composed of four flow path forming members 21 lined up in the depth direction Y. The four flow path forming members 21 constituting the flow path member 20 are open upward. In other words, the flow path member 20 is open upward.

The supply pipe 424 extends in the vertical direction Z along the frame 11a outside the cultivation shelf 11.

[0044] The pressure pump 41a pressure-feeds the water stored in the water tank 41 to the supply pipe 424 and also supplies the water to the distributor 43 of the third cultivation stage 163. The pressure pump 41a may be provided outside the water tank 41. In this case, the water tank 41 and the pressure pump 41a are connected by a pipe or the like.

[0045] The circulation mechanism 40 is configured to be able to adjust the humidity inside the cultivation shelf 11 by controlling the amount of water circulating inside the cultivation shelf 11. The circulation mechanism 40 humidifies the inside of the cultivation shelf 11 by increasing the amount of circulating water and vigorously flowing and bubbling the liquid in the liquid flow path 21a.

[0046] The circulation mechanism 40 controls the humidity inside the cultivation shelf 11 by providing and adjusting a manual on-off valve (not shown) that varies the amount of water flowing in the supply pipe 424. Alternatively, the circulation mechanism 40 may control the amount of water by providing an electric on-off valve that varies the amount of water depending on the humidity. Alternatively, the circulation mechanism 40 may control the amount of water by varying the amount of water discharged from the pressure pump 41a instead of using an on-off valve.

[0047] <Air conditioning mechanism> 1 and 3, the air conditioning mechanism 50 has an intake section 51, air conditioning piping 52, and an air blower section 53. In the cultivation device 10, the air conditioning mechanism 50 ventilates the inside of the cultivation shelf 11.

[0048] The intake section 51 is provided outside the cultivation shelf 11. The intake section 51 is placed on the floor of the cultivation room 101. The intake section 51 draws in air outside the cultivation shelf 11. The intake section 51 is, for example, a blower fan. An air conditioning pipe 52 is connected to the intake section 51. The intake section 51 introduces the drawn air into the air conditioning pipe 52.

[0049] The air blowing unit 53 is provided in the arrangement chamber 14a of the cultivation shelf 11, which is not a cultivation space 17. The air blowing unit 53 is provided in the uppermost tier 14 of the four tiers 14. In other words, the air blowing unit 53 is provided above the cultivation tier 16. Hereinafter, the arrangement chamber 14a in which the air blowing unit 53 is provided will be referred to as the air-conditioning chamber 50a. In other words, the four arrangement chambers 14a are composed of three cultivation spaces 17 and the air-conditioning chamber 50a.

[0050] The air-conditioning chamber 50a is defined by four frames 11a and a partition plate 50b. The partition plate 50b defines the lower part of the air-conditioning chamber 50a. The partition plate 50b is made of, for example, polystyrene foam. The air blower 53 is placed on the partition plate 50b. The air-conditioning chamber 50a is a space inside the cultivation shelf 11 that is divided by the partition plate 50b. Note that, for example, the air-conditioning chamber 50a may be defined by the partition plate 50b that is directly fixed to the four frames 11a.

[0051] The partition plate 50b may be, for example, a flat-type LED illuminator. In this case, the partition plate 50b covers the entire upper part of the cultivation space 17 and illuminates the cultivation space 17. The partition plate 50b divides the cultivation space 17 into an upper part and a lower part while providing the bacterial bed M with light necessary for the secondary culture period using the flat-type LED illuminator.

[0052] The air blower 53 is connected to an air conditioning pipe 52. The air blower 53 is connected to the suction section 51 via the air conditioning pipe 52. The air blower 53 blows the air sucked by the suction section 51 and introduced by the air conditioning pipe 52. The air blower 53 is configured to blow air downward. The air blower 53 is, for example, an air nozzle with an air outlet facing downward. In other words, the air conditioning mechanism 50 is configured to blow air from above the cultivation stage 16 downward. The air blower 53 is preferably configured such that a cloth or the like is wrapped around the air nozzle and the cloth or the like captures foreign matter contained in the air blown from the air nozzle while controlling the airflow to prevent a strong air current. For example, a nonwoven fabric is used as the cloth wrapped around the air nozzle.

[0053] The air conditioning mechanism 50 sends air using the air blower 53 in accordance with the humidity or carbon dioxide concentration inside the cultivation shelf 11. Note that the air conditioning mechanism 50 may also send air using the air blower 53 in accordance with both the humidity and the carbon dioxide concentration. For example, consider a case where the air conditioning mechanism 50 sends air in accordance with the carbon dioxide concentration. In this case, a sensor that measures the carbon dioxide concentration is provided inside the cultivation shelf 11. For example, the air conditioning mechanism 50 activates the intake unit 51 and the air blower 53 when the detection result of the sensor exceeds a preset threshold. When the air conditioning mechanism 50 sends air in accordance with the humidity, a sensor that measures humidity is provided inside the cultivation shelf 11.

[0054] Furthermore, the circulation mechanism 40 controls the amount of circulating water in accordance with the detection result of a sensor that measures humidity provided inside the cultivation shelf 11. When the humidity inside the cultivation shelf 11 decreases due to the air blown by the air conditioning mechanism 50, the circulation mechanism 40 humidifies the inside of the cultivation shelf 11.

[0055] <Shielding material> The first shielding member 13a surrounds the first cultivation stage 161 from the sides. More specifically, the first shielding member 13a surrounds the cultivation space 17 associated with the first cultivation stage 161 from all four sides of the cultivation shelf 11. The first shielding member 13a is a plate-like member configured to transmit light. The first shielding member 13a is, for example, an acrylic plate.

[0056] The first shielding member 13a is separate from the cultivation shelf 11. In other words, the first shielding member 13a is detachable from the cultivation shelf 11 and is configured to be movable to a stage 14 different from the first cultivation stage 161.

[0057] The second shielding member 13b surrounds the second cultivation tier 162 and the third cultivation tier 163 from the sides. The second shielding member 13b also surrounds the air-conditioning chamber 50a from the sides and above. Therefore, the four tiers 14 are surrounded by the first shielding member 13a and the second shielding member 13b from the sides of the cultivation shelf 11. The second shielding member 13b is a light-blocking sheet member. The second shielding member 13b is, for example, a blackout curtain or a black acrylic plate. In other words, the second shielding member 13b is configured to block light from entering the interior of the cultivation shelf 11.

[0058] The second shielding member 13b is separate from the cultivation shelf 11. In other words, the second shielding member 13b is detachable from the cultivation shelf 11 and is configured to be movable to a stage 14 different from the first cultivation stage 161.

[0059] The first shielding member 13a and the second shielding member 13b are each provided outside the cultivation shelf 11. The first shielding member 13a and the second shielding member 13b are each provided between the intake unit 51 and the cultivation shelf 11. In other words, the intake unit 51 is provided below the cultivation stage 16 and outside the cultivation shelf 11 more than the first shielding member 13a and the second shielding member 13b. Furthermore, the intake unit 51 draws air outside the cultivation shelf 11 more than the first shielding member 13a and the second shielding member 13b into the air conditioning piping 52.

[0060] As described above, the four tiers 14 are surrounded by the first shielding member 13a and the second shielding member 13b from the sides of the cultivating shelf 11. More specifically, the first shielding member 13a and the second shielding member 13b surround the cultivating space 17 from the sides of the cultivating shelf 11 and cover the cultivating space 17. Each of the first shielding member 13a and the second shielding member 13b prevents air from outside the cultivating shelf 11 from flowing into the inside of the cultivating shelf 11, i.e., into the cultivating space 17. Each of the first shielding member 13a and the second shielding member 13b prevents air from inside the cultivating shelf 11, i.e., the cultivating space 17, from flowing out to the outside of the cultivating shelf 11, thereby creating a moisturizing effect that maintains humidity in the cultivating space 17.

[0061] The second shielding member 13b covers the third connection pipe 423 and the portions of the air conditioning pipe 52 adjacent to the second cultivation stage 162 and the third cultivation stage 163. The first shielding member 13a covers the second connection pipe 422 and the portions of the air conditioning pipe 52 adjacent to the first cultivation stage 161. In other words, the second connection pipe 422, the third connection pipe 423, and a portion of the air conditioning pipe 52 are each provided between the cultivation shelf 11 and the first shielding member 13a and the second shielding member 13b.

[0062] Each of the first shielding member 13a and the second shielding member 13b is configured to be heat conductive. That is, in the cultivation device 10, the temperature inside the cultivation shelf 11 is adjusted by adjusting the room temperature of the cultivation room 101.

[0063] The room temperature of the cultivation room 101 is regulated by an indoor air conditioning unit 102. When the room temperature of the cultivation room 101 becomes higher than the set temperature, the indoor air conditioning unit 102 sends cool air into the cultivation room 101 from an outlet (not shown) of the air conditioning unit, and stops when the room temperature approaches the set value. Therefore, the room temperature of the cultivation room 101 fluctuates up and down, although with a small amplitude. The temperature inside the cultivation shelf 11 is indirectly transferred by heat due to the first shielding member 13a and the second shielding member 13b, without air flowing directly from the cultivation room 101 into the inside of the cultivation device 10. Therefore, the temperature inside the cultivation shelf 11 fluctuates gradually in response to the up and down fluctuations of the room temperature of the cultivation room 101, so the temperature inside the cultivation shelf 11 remains constant.

[0064] <Humidification and ventilation of the cultivation stage> First, a method for the cultivation apparatus 10 to humidify the inside of the cultivation shelf 11 will be described with reference to Figures 2 and 3. The cultivation apparatus 10 circulates water inside the cultivation shelf 11 by the circulation mechanism 40. The cultivation apparatus 10 humidifies the inside of the cultivation shelf 11 by circulating water stored in the water tank 41 using the pressure pump 41a through the supply pipe 424, three distributors 43, three liquid collecting members 44, and the first to third connection pipes 421 to 423. In Figure 3, the state in which the inside of the cultivation shelf 11 is humidified is indicated by an upward arrow. Below, a situation in which water is stored in the water tank 41 in advance is considered.

[0065] The water stored in the water tank 41 is pumped from the water tank 41 to the supply pipe 424 by the pressure pump 41a. The pumped water is sent via the supply pipe 424 to the inlet 43a of the distributor 43 provided in the third cultivation stage 163.

[0066] The distributor 43 provided in the third cultivation stage 163 distributes water flowing in through the inlet 43a to each of the four flow path forming members 21 provided in the third cultivation stage 163. The water distributed to each flow path forming member 21 flows through the liquid flow path 21a and then flows into the liquid collection chamber 44a of the liquid collection member 44 provided in the second cultivation stage 162 from the open end 21b. In other words, the water flows along the multiple flow path forming members 21. The water naturally evaporates while flowing through the liquid flow path 21a. In FIG. 3, the upward arrow indicates the flow direction of water vapor generated by the natural evaporation of water. The natural evaporation of water humidifies the cultivation space 17 of the third cultivation stage 163. The water distributed by the distributor 43 flows through the flow path member 20 and then rejoins the liquid collection member 44. The water flowing out from the open end 21b flows into the liquid collection chamber 44a through the gap in the support portion 15. The water that joins in the liquid collecting member 44 passes through the discharge hole 44b and flows into the third connecting pipe 423. The water that passes through the third cultivation stage 163 and is introduced into the third connecting pipe 423 is sent to the inlet 43a of the distributor 43 provided in the second cultivation stage 162.

[0067] The distributor 43 provided in the second cultivation stage 162 distributes water flowing in from the inlet 43a to each of the four flow path forming members 21 provided in the second cultivation stage 162. As in the third cultivation stage 163, the water distributed to each flow path forming member 21 flows through the flow path member 20 provided in the second cultivation stage 162 and then flows into the liquid collection member 44 and the second connection pipe 422. While flowing through the liquid flow path 21a, the water humidifies the cultivation space 17 of the second cultivation stage 162. The water that has flowed in the second cultivation stage 162 is sent to the inlet 43a of the distributor 43 provided in the first cultivation stage 161 via the liquid collection member 44 and the second connection pipe 422.

[0068] The distributor 43 provided in the first cultivation stage 161 distributes the water flowing in from the inlet 43a to each of the four flow path forming members 21 provided in the first cultivation stage 161. The water distributed to each flow path forming member 21 flows through the flow path member 20 provided in the first cultivation stage 161, as in the third cultivation stage 163 and the second cultivation stage 162, and then flows into the liquid collection member 44 and the first connection pipe 421.

[0069] The water that has passed through the flow path member 20 of the first cultivation stage 161 is introduced into the water tank 41 via the liquid collection member 44 and the first connection pipe 421. While flowing through the liquid flow path 21a, the water humidifies the cultivation space 17 of the first cultivation stage 161. The water introduced into the water tank 41 is stored in the water tank 41. The water stored in the water tank 41 is pressure-fed again by the pressure pump 41a to the distributor 43 provided in the third cultivation stage 163. By repeating the above process, the water is circulated inside the cultivation shelf 11 by the circulation mechanism 40 in the cultivation device 10.

[0070] Next, a method for ventilating the inside of the cultivation shelf 11 by the cultivation device 10 will be described. The cultivation device 10 ventilates the inside of the cultivation shelf 11 by the air conditioning mechanism 50. During the ventilation, the cultivation device 10 operates the circulation mechanism 40 to maintain the humidity inside the cultivation shelf 11.

[0071] The air conditioning mechanism 50 operates the intake unit 51 and the blower unit 53 when the detection results of the humidity sensor and the carbon dioxide concentration sensor exceed or fall below a preset threshold. For example, when the detection result of the carbon dioxide concentration sensor exceeds a preset threshold, the air conditioning mechanism 50 blows air using the blower unit 53. Furthermore, when the detection result of the humidity sensor falls below the preset threshold as a result of the air blowing, the air conditioning mechanism 50 stops the operation of the blower unit 53. At this time, the circulation mechanism 40 humidifies the cultivation shelf 11 by increasing the amount of circulating water.

[0072] The air conditioning mechanism 50 draws air from outside the cultivation shelf 11 through the intake section 51. The air drawn into the intake section 51 is introduced into the air blower section 53 through the air conditioning piping 52. The air blower section 53 blows the introduced air downward. In FIG. 3, the air blown downward by the air blower section 53 is indicated by a downward arrow. The air blown by the air blower section 53 stagnates in the air-conditioning chamber 50a, passes between the partition plate 50b and the frame 11a, and leaks into the third cultivation shelf 163. The air blower section 53 is provided on the stage 14 located above the third cultivation shelf 163. In other words, the air blown by the air blower section 53 passes through all the cultivation stages 16 before reaching the storage space 13. Because the storage space 13 is open in the width direction X and the depth direction Y, the air that reaches the storage space 13 flows out of the cultivation shelf 11. That is, the air conditioning mechanism 50 exhausts air below the cultivation stage 16.

[0073] [Operation of this embodiment] The operation of this embodiment will be described. The fungal beds M are arranged on three of the four cultivation tiers 14 of the cultivation shelf 11. In each cultivation tier 16, the cultivated object and the water flowing through the flow path member 20 are contained in the same cultivation space 17. The water flowing through the flow path member 20 is exposed to the cultivation space 17 through the meshes 12a of the mounting net 12. Therefore, the water evaporated in the flow path member 20 is introduced as water vapor into the cultivation space 17 containing the flow path member 20. Furthermore, the first shielding member 13a and the second shielding member 13b suppress air exchange between the outside and the inside of the cultivation shelf 11. Therefore, the water vapor resulting from the evaporation of water in the flow path member 20 is retained in each cultivation space 17 by the first shielding member 13a and the second shielding member 13b. As described above, each cultivation space 17 in the cultivation device 10 is humidified by the flow path member 20 and kept moist by the first shielding member 13a and the second shielding member 13b.

[0074] [Effects of this embodiment] The effects of this embodiment will be described. (1) A flow path member 20 through which water flows is disposed in each cultivation space 17 of the cultivation device 10. Water flowing through the flow path member 20 passes through the meshes 12a of the mounting net 12 and evaporates, humidifying the cultivation space 17 containing the flow path member 20. Each cultivation space 17 is humidified by the flow path member 20 disposed in the cultivation space 17. Each cultivation space 17 is surrounded by a first shielding member 13a or a second shielding member 13b. The first shielding member 13a and the second shielding member 13b trap water vapor in each cultivation space 17. As described above, the cultivation device 10 can humidify and moisturize each tier 14 of the cultivation shelf 11 having multiple tiers 14.

[0075] (2) When culturing the fungal bed M, carbon dioxide is released from the fungal bed M. The cultivation device 10 uses the air conditioning mechanism 50 to blow air from above to below the third cultivation stage 163, thereby discharging the carbon dioxide released from the fungal bed M to the outside of the cultivation shelf 11 via the storage space 13. As a result, the carbon dioxide concentration in each cultivation space 17 can be prevented from becoming higher than the reference value set for the cultivation space 17.

[0076] (3) The cultivation apparatus 10 can suppress air exchange between the first cultivation stage 161 and the outside of the cultivation shelf 11 while allowing light to pass through the first cultivation stage 161 by using the first shielding member 13a. Furthermore, the cultivation apparatus 10 can suppress light transmission through the second cultivation stage 162 and the third cultivation stage 163 and air exchange with the outside of the cultivation shelf 11 by using the second shielding member 13b. Here, the cultivation period of the bacterial bed M includes a primary cultivation period requiring cultivation in a light-free environment and a secondary cultivation period requiring cultivation in a bright environment. That is, the cultivation apparatus 10 can cultivate the bacterial bed M in the primary cultivation period in the second cultivation stage 162 and the third cultivation stage 163, and can cultivate the bacterial bed M in the secondary cultivation period in the first cultivation stage 161. More specifically, in the cultivation apparatus 10, the bacterial bed M in the primary cultivation period is placed in a light-free environment by using the second shielding member 13b. In addition, in the cultivation apparatus 10, the bacterial bed M in the secondary culture stage is placed in a bright environment by the first shielding member 13a.

[0077] As described above, the cultivation device 10 can cultivate, on the same cultivation shelf 11, mushroom beds M having different cultivation conditions therein. In addition, in the cultivation device 10, the intake section 51 is provided below the cultivation shelf 11, and the air conditioning pipe 52 extending from the intake section 51 is connected to the air blower section 53 while passing between the second shielding member 13b and the cultivation shelf 11. Therefore, the point where the air conditioning pipe 52 crosses the second shielding member 13b from the outside to the inside is below the second shielding member 13b. In other words, the cultivation device 10 can connect the intake section 51 and the air blower section 53 while maintaining the light blocking property inside the cultivation shelf 11, compared to, for example, a case where a hole for inserting the air conditioning pipe 52 is provided in the second shielding member 13b.

[0078] (4) For example, consider a case where a container is used as the flow path member 20, which covers the entire surface of the support portion 15 in the width direction X and the depth direction Y and has a single liquid flow path 21a through which the same amount of water as the four flow path forming members 21 can flow. In this case, the portion of the container that supports the mounting net 12 is the upper end surface of the container. By having four flow path forming members 21 as the flow path member 20, the cultivation device 10 supports the mounting net 12 by the upper end surface of each flow path forming member 21. In other words, compared to the case of, for example, the above-mentioned container, the cultivation device 10 can increase the area that supports the mounting net 12 by configuring the flow path member 20 with a plurality of flow path forming members 21.

[0079] (5) In the cultivation device 10, the flow path member 20 that humidifies each cultivation tier 16 traverses the cultivation tier 16 in the width direction X and the depth direction Y. That is, the entire interior of each cultivation tier 16 is uniformly humidified from below by the flow path member 20. As a result, compared to a case where the entire cultivation shelf 11 is humidified by a humidifier provided outside the cultivation device 10, for example, the cultivation device 10 can suppress variations in humidity around each of the bacterial beds M in each cultivation tier 16.

[0080] (6) Each cultivation stage 16 in the cultivation device 10 is humidified by natural evaporation of water flowing through the flow path member 20. As a method for humidifying the cultivation shelf 11, for example, an ultrasonic humidifier or a heating humidifier is provided on the cultivation shelf 11. Compared to the case where these humidifiers are used, the cultivation device 10 can prevent minerals contained in tap water from adhering to the fungal bed M even when tap water is used as the water.

[0081] (7) The cultivation device 10 uses only the pressure pump 41a as a driving source of water to humidify each cultivation shelf 16. In other words, the cultivation device 10 can humidify the inside of the cultivation shelf 11 while reducing power consumption compared to when using, for example, an ultrasonic humidifier or a heating humidifier.

[0082] (8) The cultivation device 10 surrounds the second cultivation stage 162 and the third cultivation stage 163 with the second shielding member 13b, which is a blackout curtain. Therefore, the cultivation device 10 can easily open and close the second cultivation stage 162 and the third cultivation stage 163.

[0083] (9) The air-conditioning chamber 50a is divided by a partition plate 50b and houses a blower 53 mounted on the partition plate 50b. Air supplied to the blower 53 from the intake 51 temporarily stagnates inside the air-conditioning chamber 50a and then leaks out of the air-conditioning chamber 50a through the edge of the partition plate 50b. The air inside the cultivation shelf 11 flows from top to bottom due to the air leaking from the air-conditioning chamber 50a. For example, compared to when the air-conditioning chamber 50a is not divided by the partition plate 50b and the blower 53 blows air directly toward the third cultivation stage 163 through the gap in the support member 15, the force of the air blown toward the fungal bed M can be reduced. As a result, the air-conditioning mechanism 50 can ventilate the inside of the cultivation shelf 11 without stressing the fungal bed M.

[0084] (10) The cultivation apparatus 10 can ventilate each cultivation shelf 11 using the air conditioning mechanism 50, so that air exchange associated with ventilation can be performed between the interior of the cultivation shelf 11 and the interior of the cultivation room 101 managed by the indoor air conditioning equipment 102. This reduces the frequency with which the bacterial bed M comes into contact with outside air compared to when the space containing the bacterial bed M directly exchanges air with outside air. When the bacterial bed M comes into contact with outside air, it is difficult to manage the cultivation environment of the bacterial bed M because the outside air environment varies depending on the season. In other words, the cultivation system 100 can easily manage the space in which the bacterial bed M is cultivated by cultivating the bacterial bed M using the cultivation apparatus 10.

[0085] (11) The first shielding member 13a and the second shielding member 13b are configured to enable heat exchange between the cultivation space 17 and the cultivation room 101. As a result, the cultivation device 10 can maintain the cultivation space 17 at a temperature controlled by the indoor air conditioning equipment 102.

[0086] [Example of change] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0087] The cultivation system 100 may include shelves for growing leafy vegetables such as lettuce in addition to the multiple cultivation devices 10. That is, the cultivation system 100 may perform mixed cultivation of mushrooms and leafy vegetables in the same cultivation room 101. In this case, the cultivation system 100 places a fungal bed M, which requires a high-humidity environment, in the cultivation device 10, and adjusts the cultivation room 101 to an environment suitable for growing leafy vegetables using the indoor air conditioning equipment 102. As a result, the cultivation system 100 can grow leafy vegetables and cultivate mushrooms in the same cultivation room 101.

[0088] The number of flow path forming members 21 constituting the flow path member 20 is not limited to four. For example, the flow path member 20 may be composed of two, three, five or more flow path forming members 21. The flow path member 20 may be formed of a single flow path forming member 21. In this case, the flow path forming member 21 is preferably large enough to cover the entire support portion 15 in the width direction X and the entire depth direction Y. In addition, the flow path forming member 21 preferably has a volume that can hold the same amount of water as when the flow path member 20 is formed of four flow path forming members 21.

[0089] The air conditioning pipe 52 may connect the intake section 51 and the blower section 53 while passing outside the second shielding member 13b. In this case, a hole through which the air conditioning pipe 52 passes is provided in the second shielding member 13b. In order to prevent light from passing through the hole, it is preferable that the hole be provided at a location farther away from the lighting device provided in the cultivation room 101. For example, if the lighting device is provided on the ceiling of the cultivation room 101, it is preferable that the hole be provided below the second shielding member 13b.

[0090] The culture device 10 may have only one of the first shielding member 13a or the second shielding member 13b as a shielding member. For example, when the culture device 10 is cultivating only the bacterial bed M in the primary culture stage, the culture device 10 may have only the second shielding member 13b as a shielding member, and all the cultivation stages 16 may be surrounded by the second shielding member 13b. Furthermore, when the culture device 10 is cultivating only the bacterial bed M in the secondary culture stage, the culture device 10 may have only the first shielding member 13a as a shielding member, and all the cultivation stages 16 may be surrounded by the first shielding member 13a. In this case, the shielding member does not need to be configured to block light from entering the inside of the culture shelf 11. In short, the culture device 10 may use either the first shielding member 13a or the second shielding member 13b as a shielding member depending on the culture status of the bacterial bed M placed on the culture shelf 11.

[0091] The intake unit 51 may be provided above the third cultivation stage 163. In this case, for example, the intake unit 51 may be fixed to the frame 11a of the cultivation shelf 11 and provided at a position away from the floor of the cultivation room 101. In addition, the blower unit 53 may be provided below the first cultivation stage 161.

[0092] The cultivation apparatus 10 may not have the air conditioning mechanism 50. In this case, the cultivation apparatus 10 may ventilate the interior of the cultivation shelf 11 by using an indoor air conditioning device 102 provided in the cultivation system 100. For example, the cultivation apparatus 10 may have an intake port with a shading function at the top of the cultivation shelf 11, and may be configured so that air from the indoor air conditioning device 102 flows into the interior of the cultivation shelf 11 through the intake port. Furthermore, the cultivation apparatus 10 may have an air intake device at the top of the cultivation shelf 11, and may take air into the interior of the cultivation shelf 11 by the device.

[0093] In the cultivation apparatus 10, the cultivated object may include other materials than the fungal bed M. For example, as shown in FIG. 4, the cultivation apparatus 10 may cultivate a fungal bed M and lettuce L as cultivated products. In this case, the cultivation apparatus 10 cultivates the lettuce L using a lighting device disposed above the first cultivation stage 161. The cultivation apparatus 10 also cultivates the fungal bed M in the second cultivation stage 162 and the third cultivation stage 163. In this case, it is preferable that each of the first cultivation stage 161, the second cultivation stage 162, and the third cultivation stage 163 is provided with a lighting device that irradiates light suitable for cultivating the lettuce L. Note that the cultivation apparatus 10 that cultivates the fungal bed M during the secondary cultivation period does not need to be provided with a lighting device if it is configured to be able to receive light from a lighting device provided in the cultivation apparatus 10 that cultivates the lettuce L.

[0094] The circulation mechanism includes a flow path member 20 provided in each of the second cultivation stage 162 and the third cultivation stage 163, but does not include a flow path member 20 provided in the first cultivation stage 161. In other words, water pressure-fed from the water tank 41 by the pressure pump 41a passes through the third cultivation stage 163 and the second cultivation stage 162, and then returns to the water tank 41 via the liquid collection member 44 provided in the second cultivation stage 162. The flow path member 20 provided in the first cultivation stage 161 is configured to be able to store liquid in the liquid flow path 21a by closing the discharge end 20b. The flow path member 20 provided in the first cultivation stage 161 stores, for example, a nutrient solution as a liquid.

[0095] The cultivation device 10 does not have a shielding member in the first cultivation stage 161. In other words, the cultivation space 17 of the first cultivation stage 161 is connected to the outside of the cultivation shelf 11. The cultivation device 10 has either the first shielding member 13a or the second shielding member 13b in the second cultivation stage 162 and the third cultivation stage 163.

[0096] In the cultivation apparatus 10, exhaust from the inside of the cultivation shelf 11 is performed through the first cultivation stage 161. That is, carbon dioxide released from the fungal bed M passes through the lettuce L and is exhausted to the outside of the cultivation shelf 11. The carbon dioxide passing through the lettuce L during the exhaust process is used for photosynthesis of the lettuce L. As described above, the cultivation apparatus 10 can cultivate a mixture of the fungal bed M and the lettuce L on a single cultivation shelf 11.

[0097] When growing lettuce L indoors, the cultivation system 100 requires that the cultivation chamber 101 have a higher carbon dioxide concentration than the atmosphere in order to promote photosynthesis of the lettuce L. For this reason, a carbon dioxide cylinder may be installed in the cultivation system 100. The cultivation system 100 can promote photosynthesis of the lettuce L without installing a carbon dioxide cylinder by cultivating the fungal bed M and cultivating the lettuce L in the same cultivation chamber 101 or cultivation shelf 11. For this reason, the cultivation system 100 can reduce the amount of power consumed by operating the indoor air conditioning equipment 102 by cultivating the fungal bed M and the lettuce L together using the cultivation device 10.

[0098] Furthermore, the cultivation system 100 can use the carbon dioxide released from the fungal bed M for photosynthesis of the lettuce L, thereby reducing the number of times the indoor air conditioning equipment 102 is operated, which is required to exhaust carbon dioxide to the outside. Operation of the indoor air conditioning equipment 102 involves exchange of air between the cultivation room 101 and the outside. In other words, by reducing the number of times the indoor air conditioning equipment 102 is operated, the cultivation system 100 can reduce the frequency of contact between the inside of the cultivation room 101 and the outside air. By reducing the frequency of contact between the inside of the cultivation room 101 and the outside air, the cultivation system 100 can suppress the invasion of pests, for example.

[0099] The cultivation apparatus 10 may cultivate lettuce L in the first cultivation stage 161 and the second cultivation stage 162, and may also cultivate a fungal bed M in the third cultivation stage 163. In this case, the circulation mechanism 40 may circulate the nutrient solution as a liquid inside the cultivation shelf 11. When the circulation mechanism 40 circulates the nutrient solution, the nutrient solution stored in the water tank 41 is pressure-fed to a distributor 43 provided in the third cultivation stage 163 by a pressure pump 41a. The nutrient solution pressure-fed to the distributor 43 provided in the third cultivation stage 163 flows through flow path members 20 provided in each of the third cultivation stage 163, the second cultivation stage 162, and the first cultivation stage 161, and then flows into the water tank 41. In other words, the cultivation apparatus 10 may circulate the nutrient solution in the circulation mechanism 40 while maintaining the configuration of the circulation mechanism 40 in the embodiment. Furthermore, the cultivation apparatus 10 may humidify the inside of the cultivation shelf 11 by the nutrient solution circulating through the circulation mechanism 40. As a result, the cultivation device 10 can cultivate the fungal bed M and the lettuce L without changing the configuration of the circulation mechanism 40 from the embodiment. Furthermore, in this case, since the nutrient solution is stored in the water tank 41, the nutrient solution absorbed by the lettuce L, for example, can be replenished by replenishing the nutrient solution into the water tank 41. As a result, replenishment of the nutrient solution can be performed more easily than, for example, when the nutrient solution is stored in the flow path member 20 of the cultivation stage 16 on which the lettuce L is placed.

[0100] When cultivating the fungal bed M and the lettuce L in the cultivation device 10, the fungal bed M and the lettuce L may each be placed on any of the cultivation tiers 16. In this case, it is preferable that the cultivation tier 16 on which the lettuce L is placed is lower than the cultivation tier 16 on which the fungal bed M is placed.

[0101] The first shielding member 13a does not have to surround the first cultivation tier 161. Furthermore, the second shielding member 13b does not have to surround the second cultivation tier 162 and the third cultivation tier 163. For example, the first shielding member 13a may surround the second cultivation tier 162. Furthermore, the second shielding member 13b may surround the first cultivation tier 161 and the third cultivation tier 163.

[0102] The mounting plate does not have to be the mounting net 12. In other words, the mounting plate does not have to be a wire mesh. For example, the mounting plate may be a thin plate with a plurality of holes. In short, it is sufficient that the mounting plate is configured to communicate the liquid flow path 21a and the cultivation space 17 when supported by the flow path member 20.

[0103] The support portion 15 does not have to be ladder-shaped. The support portion 15 only needs to have a gap that allows water flowing out of the flow path member 20 to flow into the liquid collection member 44. In short, the support portion 15 only needs to be configured to support the flow path member 20 on the cultivation shelf 11 and be interposed between the flow path member 20 and the liquid collection member 44 without interfering with the circulation of water in the circulation mechanism 40.

[0104] The number of cultivation tiers 16 that the cultivation shelf 11 has does not have to be three. In short, the cultivation shelf 11 only needs to have at least one of the multiple tiers 14 as the cultivation tier 16.
