Specifically, the front wall 110 surrounds the front side of the area of ​​the floor F where the plant P is grown. The left side wall 120 surrounds the left side of the area of ​​the floor F where the plant P is grown. The right side wall 130 surrounds the right side of the area of ​​the floor F where the plant P is grown. The rear wall 140 surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling 150 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0053] The inside I1 is separated from the outside of the structure 100A and the passage 102 by a front wall 110, a left side wall 120, a right side wall 130, a rear wall 140, and a ceiling 150. The space between the inside I1 and the outside of the structure 100A and the passage 102 is covered by the front wall 110, the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150. It becomes difficult for people, equipment, and air to pass from the outside of the structure 100A and the passage 102 to the inside I1. Therefore, air supplied to the inside I1 by the opening 121 does not easily flow from the inside I1 to the outside of the structure 100A. Air in the space I3 also does not easily flow to the inside I1. It is difficult for people or equipment to approach the inside I1. People or equipment cannot secure a working space. The working space is the space necessary for agricultural work.

[0054] A plant P is cultivated on the inside I1. Soil (not shown) in which the plant P can be planted or nutrient solution (not shown) in which the plant P can be soaked is stored in a part or all of the floor F on the inside I1. On the inside I1, the plant P is planted in soil or soaked in nutrient solution. Note that cultivating a plant P on the inside I1 does not mean that the plant P is always present on the inside I1. After the plant P is harvested, there may be cases where the plant P is not present on the inside I1. Also, there may be cases where the plant P is present on the inside I1, but the plant P cannot be seen with the naked eye on the inside I1 because it has just been planted.

[0055] Examples of the configurations of the left side wall 120, the right side wall 130, the rear wall 140, the ceiling 150, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0056] The front wall 110 (nine slats SL), the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 include transparent or semi-transparent vinyl, glass, or plastic film so that the light of the lighting in the space I3 is transmitted to the inside I1. Since the front wall 110 (nine slats SL), the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 are transparent or semi-transparent, the plant P on the inside I1 can be seen through from the outside of the structure 100A. The case 114 does not have to include transparent or semi-transparent vinyl, glass, or plastic film.

[0057] The depth of the structure 100A (in other words, the depth of the ceiling 150) is a value that ensures D1 and D2. D1 is the shortest distance in the X direction from the plant P to the front wall 110 when the plant P has finished growing. D1 is preferably 1 cm to 10 cm, but is not limited to this. D2 is the shortest distance in the negative X direction from the plant P to the rear wall 140 when the plant P has finished growing. D2 is preferably 1 cm to 10 cm, but is not limited to this.

[0058] The height of the structure 100A (in other words, the heights of the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140) is a value that ensures D3. D3 is the shortest distance in the Y direction from the plant P to the ceiling 150 when the plant P has finished growing. D3 is preferably, but not limited to, 1 to 10 centimeters.

[0059] The width of the structure 100A (in other words, the width between the front wall 110, the rear wall 140, and the ceiling 150) is a value that ensures D4 and D5. D4 is the shortest distance in the negative Z direction from the plant P to the left side wall 120 when the plant P has finished growing. D4 is preferably 1 centimeter to 10 centimeters, but is not limited to this. D5 is the shortest distance in the Z direction from the plant P to the right side wall 130 when the plant P has finished growing. D5 is preferably 1 centimeter to 10 centimeters, but is not limited to this.

[0060] The left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 are components whose configuration cannot be changed. The front wall 110 is a component whose configuration can be changed. Therefore, the structure 100A is a variable structure. Note that at least one of the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 may be a component whose configuration can be changed. Various configurations of the structure 100A will be described below.

[0061] Fig. 8 is a perspective view showing the detailed configuration of the structure 100A. Fig. 9 is a front view showing the detailed configuration of the structure 100A. Fig. 10 is a rear view showing the detailed configuration of the structure 100A. The structure 100A in Figs. 8, 9, and 10 is in a state where the slat SL is slid in the Y direction from the structure 100A in Figs. 2, 3, 4, 5, 6, and 7. A left side view, a right side view, and a plan view showing the detailed configuration of the structure 100A in this case are omitted because they are the same as Figs. 5, 6, and 7.

[0062] Of the nine slats SL, five slats SL are housed in a case 114. The front side of the structure 100A connects the outside of the structure 100A and the passage 102 with the inside I1. By changing the configuration of the front wall 110, the outside of the structure 100A and the passage 102 with the inside I1 are changed from a state in which the outside of the structure 100A and the passage 102 with the inside I1 are blocked to a state in which the outside of the structure 100A and the passage 102 with the inside I1 are connected. Since a working space is secured, a person or equipment can perform agricultural work on a plant P through the front side of the structure 100A.

[0063] Fig. 11 is a perspective view showing the detailed configuration of the structure 100A. Fig. 12 is a front view showing the detailed configuration of the structure 100A. Fig. 13 is a rear view showing the detailed configuration of the structure 100A. The structure 100A in Figs. 11, 12, and 13 is in a state where the slat SL is slid in the Y direction from the structure 100A in Figs. 8, 9, and 10. A left side view, a right side view, and a plan view showing the detailed configuration of the structure 100A in this case are omitted because they are the same as Figs. 5, 6, and 7.

[0064] The nine slats SL are housed in a case 114. The outside of the structure 100A and the passage 102 communicate with the inside I1 through the front side of the structure 100A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 100A.

[0065] 8, 9, and 10 are also modes in which the slats SL are slid in the minus Y direction from the modes of the structure 100A in Figures 11, 12, and 13. 2, 3, 4, 5, 6, and 7 are also modes in which the slats SL are slid in the minus Y direction from the modes of the structure 100A in Figures 8, 9, and 10. By changing the mode of the front wall 110, the outside of the structure 100A and the passage 102 are changed from a state in which the outside of the structure 100A and the passage 102 are connected to the inside I1 to a state in which the outside of the structure 100A and the passage 102 are blocked from the inside I1.

[0066] (3) Operation The operation of the equipment 1 when a person or a machine performs harvesting work will be described. Since the operation of the structure 100A and the operation of the structure 100B are similar, the operation of the structure 100A will be mainly described. FIG. 14 is a flowchart showing the operation of the equipment 1. Air heated by the air conditioner 11 is supplied to the inside I1 through the hose 111 and the opening 121. The structure 100A is the same as the structure 100A in FIGS. 2, 3, 4, 5, 6, and 7.

[0067] The front wall 110 (nine slats SL) covers the front side of the structure 100A. Therefore, the outside of the structure 100A and the passage 102 are separated from the inside I1. The heated air supplied to the inside I1 does not easily flow to the outside of the structure 100A. The temperature of the inside I1 is maintained higher than the temperature of the space I3. Therefore, the inside I1 provides an environment suitable for cultivating the plant P. The plant P is in a state suitable for harvesting (has finished growing). No working space is provided.

[0068] A person or device moves from the outside of the vinyl greenhouse 10 into the inside of the vinyl greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 100A. The person or device applies a force in the Y direction to one or more slats SL. Because the slats SL are connected to adjacent slats SL, the force in the Y direction is transmitted to the nine slats SL. Therefore, the nine slats SL are guided by the first guide rail 112 and the second guide rail 113 and slid in the Y direction (step S1).

[0069] As the slats SL are slid in the Y direction, the nine slats SL are stored in the case 114 starting from the top slat SL. When the five slats SL are stored in the case 114, the state of the structure 100A is changed to the state of the structure 100A in Figures 8, 9, and 10 (step S2). The state of the front wall 110 in Figure 3 is changed to the state of the front wall 110 in Figure 9. The person or device continues to apply a force in the Y direction to one or more slats SL.

[0070] As the slats SL slide in the Y direction, the nine slats SL are stored in the case 114. The state of the structure 100A is changed to the state of the structure 100A in Figures 11, 12, and 13 (step S3). The state of the front wall 110 in Figure 9 is changed to the state of the front wall 110 in Figure 12. The front side of the structure 100A communicates the outside of the structure 100A and the passage 102 with the inside I1. Now that a working space has been secured, a person or a device can perform harvesting work on the plant P. The person or a device starts harvesting work on the plant P.

[0071] When the harvesting work is completed, a person or a device applies a force in the negative Y direction to one or more of the nine slats SL stored in the case 114. Because the slats SL are connected to the other adjacent slats SL, the force in the negative Y direction is transmitted to the nine slats SL. Therefore, the nine slats SL are guided by the first guide rail 112 and the second guide rail 113 and slid in the negative Y direction (step S4).

[0072] The slats SL are lowered below the case 114. When the four slats SL are lowered from the case 114, the state of the structure 100A is changed to the state of the structure 100A in Figures 8, 9, and 10 (step S5). The state of the front wall 110 in Figure 12 is changed to the state of the front wall 110 in Figure 9. A person or device subsequently applies a force in the negative Y direction to one or more slats SL. The nine slats SL are guided by the first guide rail 112 and the second guide rail 113 and slid in the negative Y direction.

[0073] When the nine slats SL are lowered from the case 114, the state of the structure 100A is changed to the state of the structure 100A in Figures 2, 3, 4, 5, 6, and 7 (step S6). The state of the front wall 110 in Figure 9 is changed to the state of the front wall 110 in Figure 3. The front side of the structure 100A is covered by the nine slats SL. Therefore, the outside of the structure 100A and the passage 102 are blocked off from the inside I1.

[0074] (4) Features (4-1) The variable structure is a variable structure provided inside another structure, and has a plant P cultivated in the insides I1 and I2, and includes a first component whose configuration can be changed. By changing the configuration of the first component, the outside of the variable structure is changed from a state in which the outside and the insides I1 and I2 are blocked to a state in which the outside and the insides I1 and I2 are communicated with each other.

[0075] When plants are cultivated inside a structure, the inside of the structure is air-conditioned to create an environment suitable for cultivating plants. The amount of energy required for air conditioning correlates with the volume of the inside of the structure. Cultivating plants requires agricultural work on the plants, so the space required for agricultural work is secured inside the structure. In a non-variable structure whose shape cannot be changed, the space required for agricultural work is secured even when agricultural work is not being performed. Therefore, the unnecessary space is air-conditioned during the time when agricultural work is not being performed. This increases the amount of energy required for cultivating plants inside the structure, leading to increased costs for cultivating plants.

[0076] The variable structure is installed inside another structure, and plants P are cultivated on the insides I1 and I2. The variable structure can reduce the target of air conditioning from the inside of the other structure to the insides I1 and I2. Therefore, the variable structure can realize energy saving for cultivating the plants P, and can reduce the cost for cultivating the plants P.

[0077] The state in which the outside of the variable structure is blocked from the insides I1 and I2 is changed to a state in which the outside of the variable structure is communicated with the insides I1 and I2. The state in which no working space is secured is changed to a state in which a working space is secured. Therefore, the variable structure allows a person or equipment to work on the plant P on the insides I1 and I2.

[0078] When the form of a structure can be changed, the structure may be vulnerable to external physical forces. Therefore, the structure may be damaged by external forces such as strong winds or typhoons, or external forces such as accumulated snow. A variable structure is installed inside another structure. Therefore, the variable structure can protect the plant P from external physical forces. Also, the inside I1 and the inside I2 are doubly insulated from the outside. Therefore, the variable structure can realize energy savings in cultivating the plant P, and can reduce the cost of cultivating the plant P.

[0079] (4-2) The first component of the variable-type structure faces the outside passage 102, which is used by people or equipment when the people or equipment work on the plant P. By changing the aspect of the first component, the passage 102 is changed from a state in which the passage 102 is blocked from the inside I1 and the inside I2 to a state in which the passage 102 is communicated with the inside I1 and the inside I2.

[0080] The first component is more likely to receive force from a person or device on the passage 102. Therefore, the variable structure allows a person or device to easily change the state of the first component. In addition, the variable structure makes it easier for a person or device to access the plant P from the passage 102. Therefore, the variable structure makes it easier for a person or device to work on the plant P.

[0081] (4-3) The variable structure further includes a first guide rail 112 provided substantially perpendicular to an internal floor F, and a second guide rail 113 facing the first guide rail 112 and provided substantially perpendicular to the floor F. The first component is guided and slid by the first guide rail 112 and the second guide rail 113, thereby changing the state of the first component.

[0082] Since the first component is guided by the first guide rail 112 and the second guide rail 113, the force received by the first component is unlikely to be dispersed in unspecified directions. The first component is efficiently slid in a direction substantially perpendicular to the floor F. Therefore, in the variable structure, the state of the first component can be easily changed by a person or a device.

[0083] (4-4) The first component of the variable structure is the front wall 110 that is erected on the interior floor F. The variable structure further includes a ceiling 150 that faces the floor F and is in contact with the front wall 110, a rear wall 140 that is erected on the floor F, faces the front wall 110, and is in contact with the ceiling 150, a left side wall 120 that is erected on the floor F and is in contact with the front wall 110, the ceiling 150, and the rear wall 140, and a right side wall 130 that is erected on the floor F, faces the left side wall 120, and is in contact with the front wall 110, the ceiling 150, and the rear wall 140. The front wall 110, the ceiling 150, the rear wall 140, the left side wall 120, and the right side wall 130 surround the area of ​​the floor F that faces the ceiling 150, thereby forming the inside I1 and the inside I2.

[0084] The variable structure can enclose the area of ​​the floor F and form the insides I1 and I2 even without having a component on the bottom surface facing the ceiling 150. The variable structure can be installed later even when a plant P is already being cultivated on the floor F of another structure. Therefore, the variable structure can reduce the effort and cost required for installation.

[0085] (4-5) In the variable structure, at least one of the front wall 110, the ceiling 150, the rear wall 140, the left side wall 120, and the right side wall 130 transmits outside light to the inside I1 and the inside I2.

[0086] A light source may be provided in another structure in which the variable structure is provided. The variable structure transmits light from outside the variable structure to the inside I1 and the inside I2. Therefore, the variable structure can illuminate the plants P on the inside I1 and the inside I2 with light from outside the variable structure.

[0087] (4-6) The variable-type structure is further provided with a supply section for supplying conditioned air from the air conditioner 11 on the outside to the inside I1 and the inside I2.

[0088] Therefore, the variable structure can air-condition the insides I1 and I2 by the supply unit, even if air conditioners are not provided on the insides I1 and I2. Also, since the variable structure does not require air conditioners on the insides I1 and I2, the insides I1 and I2 can be used more widely for cultivating plants P.

[0089] (4-7) The supply section of the variable structure is provided substantially vertically below the substantially vertical center of the variable structure.

[0090] In order to create an environment suitable for plant growth, the space in which the plants are located may be heated or humidified. Heated air is lighter than unheated air, so it moves from bottom to top. Humidified air is also lighter than unhumidified air, so it moves from bottom to top.

[0091] The variable structure has a supply section disposed approximately vertically below the approximate vertical center of the variable structure. When heated air or humidified air is supplied to the supply section, the heated air or humidified air moves from approximately vertically below to approximately vertically above. The variable structure forms an airflow on the insides I1 and I2, making it difficult for temperature and humidity unevenness to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for cultivating plants P.

[0092] (4-8) The variable type structure is further provided with exhaust portions for exhausting the air in the insides I1 and I2 from the insides I1 and I2 to the outside.

[0093] As air is supplied to the inside of the structure, the air inside the structure may be exhausted through gaps in the structure. In this case, the air cannot be smoothly exhausted, and the air pressure inside the structure may rise. In addition, the gaps in the structure may open up over time. Furthermore, the air flow inside the structure may become random depending on the location of the gaps, which may cause temperature or humidity unevenness.

[0094] The variable structure exhausts the air on the inside I1 and the inside I2 from the inside I1 and the inside I2 to the outside of the variable structure. Therefore, the variable structure can keep the air pressure and airflow on the inside I1 and the inside I2 stable. In addition, the variable structure can maintain the airtightness of the variable structure for a longer period of time.

[0095] (4-9) The variable structure is such that the discharge portion is provided on a component of the variable structure opposite to the component of the variable structure on which the supply portion is provided.

[0096] In some cases, an opening from the inside to the outside of a structure is provided near an opening from the outside to the inside of the structure. In this case, air supplied from the outside to the inside of the structure may be immediately exhausted from the inside to the outside of the structure. This may cause temperature or humidity unevenness to occur between the vicinity of the opening from the outside to the inside of the structure and the distant area.

[0097] The variable structure has an exhaust section provided in a component of the variable structure facing the component of the variable structure in which the supply section is provided. The variable structure forms airflows on the insides I1 and I2, making it difficult for temperature or humidity unevenness to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 environments more suitable for growing plants P.

[0098] (4-10) In the variable structure, when the supply section is provided substantially vertically below the substantially vertical center of the variable structure, the discharge section is provided substantially vertically above the substantially vertical center of the variable structure.

[0099] The variable structure forms air currents on the insides I1 and I2, making it difficult for temperature or humidity unevenness to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 environments more suitable for growing plants P.

[0100] (4-11) The exhaust portion of the variable structure is connected to a hose that is connected to the intake port of the air conditioner 11.

[0101] The air supplied from the air conditioner 11 to the inside I1 and the inside I2 via the supply unit is discharged again to the suction port of the air conditioner 11. The air circulating between the air conditioner 11 and the inside I1 and the inside I2 is unlikely to flow into the space I3. The air conditioner 11 can limit the air that is the subject of air conditioning to the air circulating between the air conditioner 11 and the inside I1 and the inside I2. Therefore, the variable structure can realize energy savings in cultivating the plant P, and can reduce the cost of cultivating the plant P.

[0102] (5) Variations Regarding the modified example of the first embodiment, the description will be centered on the differences from the first embodiment and the description of the similarities to the first embodiment will be omitted.

[0103] (5-1) Variation 1A The case 114 may be provided so as to double as the ceiling 150. FIG. 15 is a perspective view showing a detailed configuration of the structure 100A according to the modified example 1A. For example, the case 114 of the modified example 1A may be provided at the position of the ceiling 150 of the first embodiment. In the modified example 1A, the case 114 is an example of the ceiling 150. The case 114 faces the floor F and contacts the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140. The modified example 114 is approximately parallel to the floor F and approximately horizontal. The case 114 surrounds the upper side of the area of ​​the floor F where the plant P is cultivated.

[0104] (5-2) Variation 1B The case 114 may be provided in front of the first guide rail 112 and the second guide rail 113. Fig. 16 is a perspective view showing a detailed configuration of a structure 100A according to modification 1B.

[0105] (5-3) Variation 1C (5-3-1) Structure The structure 100A and the structure 100B in any of the first embodiment, modification 1A, and modification 1B may be provided inside a mushroom cultivation facility 20 instead of inside the vinyl greenhouse 10. The mushroom cultivation facility 20 refers to a building or a vinyl greenhouse in which mushrooms M are cultivated. Fig. 17 is a schematic diagram showing the overall configuration of the facility 1 according to modification 1C.

[0106] A rack R is provided on the inner side I1 and the inner side I2. A mycelium bottle B is placed on the rack R. Mushrooms M are cultivated in the mycelium bottle B. The mycelium bottle B and the mushrooms M are collectively referred to as a set MS. Note that the mushrooms M may be cultivated in a mushroom bed bag instead of the mycelium bottle B. The passage 102 is a passage in the space I3 used by people or equipment when mushroom work (work generally performed on mushrooms M in the mushroom cultivation facility 20) is being performed.

[0107] Mushroom work is work done by humans or machines on mushrooms M. Examples of mushroom work include inoculation work for planting mushroom M seed cultures, cultivation work for cultivating mushrooms M, harvesting work for harvesting all or part of mushrooms M, and other mushroom work. The work space is the space necessary for mushroom work.

[0108] FIG. 18 is a perspective view showing a detailed configuration of the structure 100A according to Modification 1C. FIG. 19 is a front view showing a detailed configuration of the structure 100A according to Modification 1C. FIG. 20 is a rear view showing a detailed configuration of the structure 100A according to Modification 1C. FIG. 21 is a left side view showing a detailed configuration of the structure 100A according to Modification 1C. FIG. 22 is a right side view showing a detailed configuration of the structure 100A according to Modification 1C. FIG. 23 is a plan view showing a detailed configuration of the structure 100A according to Modification 1C.

[0109] The rack R has a plurality of stands 180 arranged substantially perpendicular to the floor F. For example, the rack R has three stands 180 arranged substantially perpendicular to the floor F. Mushrooms M are grown on each stand 180.

[0110] The depth of the structure 100A (in other words, the depth of the ceiling 150) is a value that ensures D6 and D7. D6 is the shortest distance in the X direction from the platform 180 to the front wall 110. D6 is preferably, but not limited to, 1 to 5 centimeters. D7 is the shortest distance in the negative X direction from the platform 180 to the rear wall 140. D7 is preferably, but not limited to, 1 to 5 centimeters.

[0111] The height of the structure 100A (in other words, the height between the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140) is a value that ensures D8. D8 is the shortest distance in the Y direction from the mushrooms M on the top platform 180 to the ceiling 150 when the mushrooms M have finished growing. D8 is preferably, but not limited to, 1 to 10 centimeters.

[0112] The width of structure 100A (in other words, the width between front wall 110, rear wall 140, and ceiling 150) is the value that ensures D9 and D10. D9 is the shortest distance in the negative Z direction from platform 180 to left wall 120. D9 is preferably, but is not limited to, 1 to 5 centimeters. D10 is the shortest distance in the Z direction from platform 180 to right wall 130. D10 is preferably, but is not limited to, 1 to 5 centimeters.

[0113] (5-3-2) Features (5-3-2-1) The variable structure is a variable structure provided inside another structure, and has insides I1 and I2 on which mushrooms M are cultivated, and includes a first component whose configuration can be changed. By changing the configuration of the first component, the outside of the variable structure is changed from a state in which the outside and the insides I1 and I2 are blocked to a state in which the outside and the insides I1 and I2 are communicated with each other.

[0114] When mushrooms are cultivated inside a structure, the interior of the structure is air-conditioned to create an environment suitable for mushroom cultivation. Because mushroom cultivation requires work on the mushrooms, the space required for the work is secured inside the structure. In a non-variable structure whose form cannot be changed, the space required for the work is secured even when no work is being performed. Therefore, the unnecessary space is air-conditioned during the time when no work is being performed. This increases the amount of energy required for mushroom cultivation inside the structure, leading to increased costs associated with mushroom cultivation.

[0115] The variable structure is provided inside another structure, and mushrooms M are cultivated in the insides I1 and I2. Therefore, the variable structure can realize energy saving for the cultivation of the mushrooms M, and can reduce the cost for the cultivation of the mushrooms M.

[0116] The variable structure enables people or equipment to work on the mushrooms M on the inside I1 and inside I2. The variable structure can also protect the mushrooms M from physical external forces. Furthermore, the variable structure can achieve energy savings in cultivating the mushrooms M due to double insulation, thereby reducing the cost of cultivating the mushrooms M.

[0117] (5-3-2-2) The first component of the variable type structure faces the outer passage 102, which is used by a person or an apparatus when the person or the apparatus works on the mushrooms M. By changing the aspect of the first component, the passage 102 is changed from a state in which the passage 102 is blocked from the insides I1 and I2 to a state in which the passage 102 is communicated with the insides I1 and I2.

[0118] Therefore, the variable structure makes it easier for humans or equipment to work on the mushrooms M.

[0119] (5-4) Variation 1D The structure 100A and the structure 100B in any of the first embodiment, the modified example 1A, and the modified example 1B may be provided inside a plant factory 30 instead of inside a vinyl greenhouse 10. The plant factory 30 refers to a building in which a plant P is cultivated. Fig. 24 is a schematic diagram showing the overall configuration of the facility 1 according to the modified example 1D.

[0120] Racks R are provided on the inside I1 and inside I2. Plants P are grown on the racks R. The plants P are planted in soil (not shown) on the racks R or immersed in a nutrient solution (not shown) on the racks R. The structures 100A and 100B, or the racks R, may be provided with lighting devices (not shown) that serve as light sources for the plants P. The configuration of the racks R is similar to that of the modified example 1C, and therefore a description thereof will be omitted.

[0121] The depth and width of the structure 100A of the modified example 1D are the same as those of the structure 100A of the modified example 1C, and therefore will not be described. The height of the structure 100A (in other words, the heights of the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140) is a value that ensures D11 (not shown). D11 is the shortest distance in the Y direction from the plant P to the ceiling 150 when the plant P has finished growing. D11 is preferably, but not limited to, 1 to 10 centimeters.

[0122] (5-5) Variation 1E (5-5-1) Structure The structure 100A and the structure 100B in any of the first embodiment, the modification 1A, and the modification 1B may be provided inside a server room 40 instead of inside the vinyl greenhouse 10. The server room 40 is a room in which a server is installed. The server room 40 may be provided inside other buildings (data centers, commercial buildings, industrial buildings, agricultural buildings, residential buildings, etc.). FIG. 25 is a schematic diagram showing the overall configuration of the facility 1 according to the modification 1E.

[0123] In the inside I1 and the inside I2, a server SV is installed instead of cultivating plants P. The passage 102 is a passage in the space I3 used for a person or device when server work (work performed by a server engineer on the server SV) is performed.

[0124] Server work is work performed by humans or equipment on a server SV. Examples of server work include maintenance work to maintain a server SV, replacement work to replace all or part of a server SV, test work to test a server SV, and other server work. Work space is the space required for server work.

[0125] Space I3, which is outside the structures 100A and 100B and inside the server room 40, may be used as a business space with desks and chairs placed therein. Desks and chairs may be placed in place of either the structure 100A or the structure 100B and used as a business space. Other machines requiring air conditioning may be installed in the insides I1 and I2 in addition to or instead of the server SV.

[0126] FIG. 26 is a perspective view showing a detailed configuration of the structure 100A according to Modification 1E. FIG. 27 is a front view showing a detailed configuration of the structure 100A according to Modification 1E. FIG. 28 is a rear view showing a detailed configuration of the structure 100A according to Modification 1E. FIG. 29 is a left side view showing a detailed configuration of the structure 100A according to Modification 1E. FIG. 30 is a right side view showing a detailed configuration of the structure 100A according to Modification 1E. FIG. 31 is a plan view showing a detailed configuration of the structure 100A according to Modification 1E.

[0127] The opening 121 is provided approximately vertically above the approximate vertical center of the left side wall 120. In other words, the opening 121 is provided approximately vertically above the approximate vertical center of the structure 100A.

[0128] The opening 131 is provided substantially vertically below the substantially vertical center of the right side wall 130. In other words, the opening 131 is provided substantially vertically below the substantially vertical center of the structure 100A.

[0129] The depth of the structure 100A (in other words, the depth of the ceiling 150) is a value that ensures D12 and D13. D12 is the shortest distance in the X direction from the server SV to the front wall 110. D12 is preferably, but not limited to, 5 to 20 centimeters. D13 is the shortest distance in the negative X direction from the server SV to the rear wall 140. D13 is preferably, but not limited to, 15 to 40 centimeters.

[0130] The height of the structure 100A (in other words, the heights of the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140) is a value that ensures D14. D14 is the shortest distance in the Y direction from the server SV to the ceiling 150. D14 is preferably, but not limited to, 5 to 20 centimeters.

[0131] The width of structure 100A (in other words, the width between front wall 110, rear wall 140, and ceiling 150) is the value that ensures D15 and D16. D15 is the shortest distance in the negative Z direction from server SV to left side wall 120. D15 is preferably, but not limited to, 5 centimeters to 20 centimeters. D16 is the shortest distance in the Z direction from server SV to right side wall 130. D16 is preferably, but not limited to, 5 centimeters to 20 centimeters.

[0132] (5-5-2) Features (5-5-2-1) The variable structure is a variable structure provided inside another structure, and includes a first component whose state can be changed, in which a server SV is installed on the insides I1 and I2. By changing the state of the first component, the outside of the variable structure is changed from a state in which the outside and the insides I1 and I2 are blocked to a state in which the outside and the insides I1 and I2 are communicated with each other.

[0133] When a server is installed inside a structure, the inside of the structure is air-conditioned to make the inside of the structure an environment suitable for operating the server. Since operating a server requires work to be done on the server, the space required for server work is secured inside the structure. In a non-variable structure whose shape cannot be changed, the space required for server work is secured even when no server work is being performed. Therefore, air is conditioned in the unnecessary space during times when server work is not being performed. This increases the amount of energy required to operate the server inside the structure, leading to increased costs for operating the server.

[0134] The variable structure is provided inside another structure, and the server SV is installed on the inside I1 and the inside I2. Therefore, the variable structure can realize energy saving for the operation of the server SV, and can reduce the cost for the operation of the server SV.

[0135] The variable type structure allows a person or device to work on the server SV on the inside I1 and inside I2. The variable type structure can also protect the server SV from physical external forces. Furthermore, the variable type structure can achieve energy saving in operating the server SV due to double insulation, and can reduce the cost of operating the server SV.

[0136] (5-5-2-2) The variable structure has a first component facing an outside passage 102 that is used by a person or a device when the person or the device performs work on the server SV. By changing the aspect of the first component, the passage 102 is changed from a state in which the passage 102 is blocked from the inside I1 and the inside I2 to a state in which the passage 102 is communicated with the inside I1 and the inside I2.

[0137] Therefore, the variable structure makes it easier for a person or device to work on the server SV.

[0138] (5-5-2-3) The supply section of the variable structure is provided substantially vertically above the substantially vertical center of the variable structure.

[0139] In order to create an environment suitable for server operation, the space in which the server is installed may be cooled or dehumidified. Cooled air is heavier than uncooled air, so it moves from top to bottom. Dehumidified air is also heavier than unhumidified air, so it moves from top to bottom.

[0140] The variable structure has a supply section disposed approximately vertically above the approximately vertical center of the variable structure. When cooled air or dehumidified air is supplied to the supply section, the cooled air or dehumidified air moves from approximately vertically above to approximately vertically below. The variable structure forms an airflow on the insides I1 and I2, making it difficult for temperature and humidity unevenness to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for the operation of the server SV.

[0141] (5-5-2-4) In the variable structure, when the supply section is provided substantially vertically above the substantially vertical center of the variable structure, the discharge section is provided substantially vertically below the substantially vertical center of the variable structure.

[0142] The variable structure forms an airflow on the insides I1 and I2, making it difficult for temperature or humidity unevenness to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for the operation of the server SV.

[0143] (5-6) Variation 1F (5-6-1) Structure The structure 100A and the structure 100B in any of the first embodiment, the modified example 1A, and the modified example 1B may be provided inside a warehouse 50 instead of inside a vinyl greenhouse 10. Examples of the warehouse 50 include, but are not limited to, a freezer warehouse and a refrigerated warehouse. FIG. 32 is a schematic diagram showing the overall configuration of the facility 1 according to the modified example 1F. In the inside I1 and the inside I2, instead of cultivating plants P, products G are stored.

[0144] Specifically, racks R are provided on the inside I1 and inside I2, and products G are stored on the racks R. The products G include products packaged in cardboard boxes or the like. The racks R are similar to those in the modified example 1C, and therefore a description thereof will be omitted. The aisles 102 are aisles in the space I3 that are used by people or equipment when warehouse work is performed.

[0145] Warehouse work is work performed by humans or equipment (robots, vehicles, etc.) on goods G. Examples of warehouse work include loading work for loading goods G onto racks R, picking work for picking goods G from racks R, checking work for checking the quantity and condition of goods G, and other warehouse work. The work space is a space necessary for warehouse work. A roller conveyor (not shown) for transporting goods G may be provided inside warehouse 50.

[0146] The depth and width of the structure 100A are the same as those of the modified example 1C, and therefore description thereof will be omitted. The height of the structure 100A (in other words, the height of the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140) is a value that ensures D17 (not shown). D17 is the shortest distance in the Y direction from the product G stored on the top platform 180 of the rack R to the ceiling 150. D17 is preferably 5 to 10 centimeters, but is not limited to this.

[0147] The openings 121 and 131 are similar to those in the modified example 1E, and therefore the description thereof will be omitted.

[0148] (5-6-2) Features (5-6-2-1) The variable structure is a variable structure provided inside another structure, and has an inner side I1 and an inner side I2 in which a commodity G is stored, and includes a first component whose state can be changed. By changing the state of the first component, the outside of the variable structure is changed from a state in which the outside and the insides I1 and I2 are blocked to a state in which the outside and the insides I1 and I2 are communicated with each other.

[0149] When goods are stored inside a structure, the inside of the structure is air-conditioned to make the inside of the structure an environment suitable for storing the goods. Since storing goods requires warehousing work, the space required for warehousing work is secured inside the structure. In a non-variable structure whose shape cannot be changed, the space required for warehousing work is secured even when warehousing work is not being performed. Therefore, air is conditioned in the unnecessary space during the time when warehousing work is not being performed. This increases the amount of energy required to store goods inside the structure, leading to increased costs for storing goods.

[0150] The variable structure is installed inside another structure, and the product G is stored in the inside I1 and the inside I2. Therefore, the variable structure can realize energy saving for storing the product G, and can reduce the cost for storing the product G.

[0151] The variable structure enables a person or machine to work on the goods G in the inside I1 and inside I2. The variable structure can also protect the goods G from physical external forces. Furthermore, the variable structure can achieve energy savings in storing the goods G due to double insulation, and can reduce the cost of storing the goods G.

[0152] (5-6-2-2) The variable-type structure has a first component facing an outer passage 102 that is used by a person or a device when the person or the device performs work on the product G. By changing the aspect of the first component, the passage 102 is changed from a state in which the passage 102 is blocked from the insides I1 and I2 to a state in which the passage 102 is communicated with the insides I1 and I2.

[0153] Therefore, the variable structure makes it easier for people or equipment to work on the product G.

[0154] (5-7) Variation 1G (5-7-1) Configuration The structure 100A and the structure 100B in any of the first embodiment, the modified example 1A, and the modified example 1B may be provided inside the livestock barn 60 instead of inside the vinyl greenhouse 10. FIG. 33 is a schematic diagram showing the overall configuration of the facility 1 according to the modified example 1G. In the inside I1 and the inside I2, livestock L are raised instead of cultivating plants P. The livestock L in FIG. 33 are cows, but are not limited thereto. The passage 102 is a passage in the space I3 used by people or equipment when livestock work is performed.

[0155] Livestock work is work done by humans or machines on livestock L. Examples of livestock work include feeding livestock L, cleaning work to remove feces and urine from livestock L, health work to treat, prevent, and breed livestock L, harvesting work to harvest eggs, hair, meat, milk, etc. from livestock L, and other livestock work. The work space is the space necessary for livestock work.

[0156] The depth of the structure 100A is the depth of the livestock L (horizontal length from the face to the rump of the livestock L) plus 30 cm to 1 m, but is not limited to this. The width of the structure 100A is the sum of the widths of all the livestock L housed in the structure 100A (the longest length of the livestock L in the direction perpendicular to the depth of the livestock L on the horizontal plane) plus 50 cm to 2 m, but is not limited to this. The height of the structure 100A is the height of the person performing livestock work plus 10 cm to 30 cm, but is not limited to this.

[0157] (5-7-2) Features (5-7-2-1) The variable structure is a variable structure provided inside another structure, and has insides I1 and I2 in which livestock L are raised, and includes a first component whose configuration can be changed. By changing the configuration of the first component, the outside of the variable structure is changed from a state in which the outside and the insides I1 and I2 are blocked to a state in which the outside and the insides I1 and I2 are communicated with each other.

[0158] When livestock are raised inside a structure, the interior of the structure is air-conditioned to create an environment suitable for raising livestock. Raising livestock requires livestock work, so the space required for livestock work is secured inside the structure. In a non-variable structure whose shape cannot be changed, the space required for livestock work is secured even when livestock work is not being performed. Therefore, unnecessary space is air-conditioned during times when livestock work is not being performed. This increases the amount of energy required to raise livestock inside the structure, leading to increased costs associated with raising livestock.

[0159] The variable structure is provided inside another structure, and livestock L are raised in the insides I1 and I2. Therefore, the variable structure can realize energy saving for raising the livestock L, and can reduce the cost for raising the livestock L.

[0160] The variable structure enables people or equipment to work on the livestock L on the inside I1 and inside I2. The variable structure can also protect the livestock L from physical external forces. Furthermore, the variable structure can achieve energy savings in raising the livestock L due to its double insulation, thereby reducing the costs associated with raising the livestock L.

[0161] (5-7-2-2) The first component of the convertible structure faces the outside passage 102, which is used by people or equipment when the people or equipment work on livestock L. By changing the aspect of the first component, the passage 102 is changed from a state in which the passage 102 is blocked from the insides I1 and I2 to a state in which the passage 102 is communicated with the insides I1 and I2.

[0162] Therefore, the convertible structure makes it easier for people or equipment to work on the livestock L.

[0163] (5-8) Variation 1H (5-8-1) Configuration The structure 100A and the structure 100B in any of the first embodiment, the modified example 1A, and the modified example 1B may be provided inside the land-based farm 70 instead of inside the vinyl greenhouse 10. FIG. 34 is a schematic diagram showing the overall configuration of the facility 1 according to the modified example 1H. In the inside I1 and the inside I2, instead of cultivating the plants P, the aquatic organisms Q are cultivated. Specifically, the aquarium A is provided in the inside I1 and the inside I2, and the aquatic organisms Q are cultivated in the water W stored in the aquarium A. The aquatic organisms Q in FIG. 34 are fish, but are not limited thereto. The passage 102 is a passage in the space I3 used by people or equipment when the aquaculture work is performed.

[0164] Aquaculture work is work performed by humans or equipment on aquatic organism Q. Examples of aquaculture work include feeding aquatic organism Q, cleaning work to remove feces and urine from aquatic organism Q and clean tank A, water work to supply water W, replace water W, and test the quality of water W, health work to treat, prevent, and breed aquatic organism Q, harvesting work to harvest eggs, meat, etc. of aquatic organism Q, and other aquaculture work. The work space is the space necessary for aquaculture work.

[0165] The depth of the structure 100A is the depth of the tank A plus 5 cm to 30 cm, but is not limited to this. The width of the structure 100A is the width of the tank A plus 5 cm to 30 cm, but is not limited to this. The height of the structure 100A is the height of the person performing the aquaculture work plus 10 cm to 30 cm, but is not limited to this.

[0166] (5-8-2) Features (5-8-2-1) The variable structure is a variable structure provided inside another structure, and has an inner side I1 and an inner side I2 in which aquatic organisms Q are cultivated, and includes a first component whose configuration can be changed. By changing the configuration of the first component, the outside of the variable structure is changed from a state in which the outside and the insides I1 and I2 are blocked to a state in which the outside and the insides I1 and I2 are communicated with each other.

[0167] When cultivating aquatic organisms inside a structure, the interior of the structure is air-conditioned to create an environment suitable for cultivating the aquatic organisms. Cultivating aquatic organisms requires cultivating the organisms, so the space required for the cultivating work is secured inside the structure. In a non-variable structure whose shape cannot be changed, the space required for the cultivating work is secured even when no cultivating work is being performed. Therefore, the unnecessary space is air-conditioned during the times when no cultivating work is being performed. This increases the amount of energy required to cultivate aquatic organisms inside the structure, leading to increased costs associated with cultivating the aquatic organisms.

[0168] The variable structure is installed inside another structure, and aquatic organisms Q are cultivated in the insides I1 and I2. Therefore, the variable structure can realize energy saving for cultivating the aquatic organisms Q, and can reduce the cost for cultivating the aquatic organisms Q.

[0169] The variable type structure allows humans or equipment to work on the aquatic life Q on the inside I1 and inside I2. The variable type structure can also protect the aquatic life Q from physical external forces. Furthermore, the variable type structure can achieve energy savings in cultivating the aquatic life Q through double insulation, thereby reducing the cost of cultivating the aquatic life Q.

[0170] (5-8-2-2) The first component of the variable type structure faces the outside passage 102, which is used by a person or an apparatus when the person or the apparatus works on the aquatic organism Q. By changing the aspect of the first component, the passage 102 is changed from a state in which the passage 102 is blocked from the inside I1 and the inside I2 to a state in which the passage 102 is communicated with the inside I1 and the inside I2.

[0171] Therefore, the convertible structure makes it easier for humans or equipment to work on the aquatic organisms Q.

[0172] (5-9) Variation 1I The front wall 110 of the first embodiment and modifications 1A, 1B, 1C, 1D, 1E, 1F, 1G, and 1H may be changed in appearance by control of a control device (not shown). In other words, the slat SL may slide on the first guide rail 112 and the second guide rail 113 by control of the control device.

[0173] <Second embodiment> (1) Overall structure The overall configuration of the facility 2 according to the second embodiment will be described.

The air conditioner 11 also communicates with the inside I5 via two hoses (not shown) different from the hoses 115 and 116. Air conditioned by the air conditioner 11 is supplied to the insides I4 and I5 via the hoses 115 and 116, etc.

The structure 200B is a variable structure in which the state of the structure 200B can be changed by the operation of the structure 200B. The structures of the structure 200A and the structure 200B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 200A is similar to that of the structure 200B. The structure and function of the structure 200A will be described below.

In other words, the first opening 221 is provided substantially vertically below the substantially vertical center of the structure 200A. The first opening 221 is provided substantially rearward of the substantially X-direction center of the structure 200A. The first opening 221 is an opening for supplying heated air from the air conditioner 11 to the inside I4. The first opening 221 is also an opening for supplying humidified air from the air conditioner 11 to the inside I4.

In other words, the second opening 222 is provided approximately vertically above the approximate vertical center of the structure 200A. The second opening 222 is provided approximately rearward of the approximate X-direction center of the structure 200A. The second opening 222 is an opening for supplying cooled air from the air conditioner 11 to the inside I4.

[0188] The right side wall 230 faces the left side wall 220 and stands substantially perpendicular to the floor F. The right side wall 230 is in contact with the front wall 210, the rear wall 240, and the ceiling 250. The right side wall 230 is provided with an opening 231 that communicates with the outside of the structure 200A.

For example, the opening 231 is connected to a hose (not shown) that is connected to the intake port of the air conditioner 11. The air on the inside I4 flows to the intake port of the air conditioner 11 through the opening 231 and the hose.

[0191] The opening 231 may be provided in any one of the front wall 210, the left wall 220, the rear wall 240, and the ceiling 250, instead of the right side wall 230. The opening 231 may be provided in at least one of the front wall 210, the left side wall 220, the rear wall 240, and the ceiling 250, in addition to the right side wall 230. The opening 231 may be provided forward of approximately the center of the structure 200A in the X direction. The opening 231 may be connected to a hose (not shown) that is connected to a location outside the vinyl greenhouse 10 other than the suction port of the air conditioner 11.

[0192] The rear wall 240 faces the front wall 210, and stands substantially perpendicular to the floor F. The rear wall 240 is in contact with the left side wall 220, the right side wall 230, and the ceiling 250.

[0193] The ceiling 250 faces the floor F, and is approximately parallel to the floor F and approximately horizontal. The ceiling 250 is in contact with the front wall 210, the left side wall 220, the right side wall 230, and the rear wall 240.

[0194] The area of ​​the floor F facing the ceiling 250 is surrounded by the front wall 210, the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250, forming an inside I4. Specifically, the front wall 210 surrounds the front side of the area of ​​the floor F where the plant P is grown. The left side wall 220 surrounds the left side of the area of ​​the floor F where the plant P is grown. The right side wall 230 surrounds the right side of the area of ​​the floor F where the plant P is grown. The rear wall 240 surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling 250 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0195] The inside I4 is separated from the outside of the structure 200A and the passage 102 by a front wall 210, a left side wall 220, a right side wall 230, a rear wall 240, and a ceiling 250. The space between the inside I4 and the outside of the structure 200A and the passage 102 is covered by the front wall 210, the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250. It becomes difficult for people, equipment, and air to pass from the outside of the structure 200A and the passage 102 to the inside I4. Therefore, the air supplied to the inside I4 by the first opening 221 and the second opening 222 does not easily flow from the inside I4 to the outside of the structure 200A. The air in the space I6 also does not easily flow to the inside I4. It is difficult for people or equipment to approach the inside I4. People or equipment cannot secure a working space.

[0196] A plant P is cultivated on the inner side I4. Soil (not shown) in which the plant P can be planted or a nutrient solution (not shown) in which the plant P can be soaked is stored in a part or all of the floor F on the inner side I4. On the inner side I4, the plant P is planted in soil or soaked in nutrient solution. Note that cultivating a plant P on the inner side I4 does not mean that the plant P is always present on the inner side I4. After the plant P is harvested, there may be cases where the plant P is not present on the inner side I4. Also, there may be cases where the plant P is present on the inner side I4, but the plant P cannot be confirmed by the naked eye on the inner side I4 because it has just been planted.

[0197] Examples of the configurations of the left side wall 220, the right side wall 230, the rear wall 240, the ceiling 250, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0198] The front wall 210 (14 slats SL), the left wall 220, the right wall 230, the rear wall 240, and the ceiling 250 include transparent or semi-transparent vinyl, glass, or plastic film so that the light of the lighting in the space I6 is transmitted to the inside I4. Since the front wall 210 (14 slats SL), the left wall 220, the right wall 230, the rear wall 240, and the ceiling 250 are transparent or semi-transparent, the plant P on the inside I4 can be seen through from the outside of the structure 200A. The case 213 does not have to include transparent or semi-transparent vinyl, glass, or plastic film.

[0199] The depth of the structure 200A (in other words, the depth of the ceiling 250) is a value that ensures D18 and D19. D18 is the shortest distance in the X direction from the plant P to the front wall 210 when the plant P has finished growing. D18 is preferably 1 cm to 10 cm, but is not limited to this. D19 is the shortest distance in the negative X direction from the plant P to the rear wall 240 when the plant P has finished growing. D19 is preferably 1 cm to 10 cm, but is not limited to this.

[0200] The height of the structure 200A (in other words, the heights of the front wall 210, the left side wall 220, the right side wall 230, and the rear wall 240) is a value that ensures D20. D20 is the shortest distance in the Y direction from the plant P to the ceiling 250 when the plant P has finished growing. D20 is preferably, but not limited to, 1 to 10 centimeters.

[0201] The width of the structure 200A (in other words, the width between the front wall 210, the rear wall 240, and the ceiling 250) is a value that ensures D21 and D22. D21 is the shortest distance in the negative Z direction from the plant P to the left side wall 220 when the plant P has finished growing. D21 is preferably 1 centimeter to 10 centimeters, but is not limited to this. D22 is the shortest distance in the Z direction from the plant P to the right side wall 230 when the plant P has finished growing. D22 is preferably 1 centimeter to 10 centimeters, but is not limited to this.

[0202] The left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250 are components whose configuration cannot be changed. The front wall 210 is a component whose configuration can be changed. Therefore, the structure 200A is a variable structure. Note that at least one of the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250 may be a component whose configuration can be changed. Various configurations of the structure 200A will be described below.

[0203] Fig. 42 is a perspective view showing the detailed configuration of the structure 200A. Fig. 43 is a front view showing the detailed configuration of the structure 200A. Fig. 44 is a rear view showing the detailed configuration of the structure 200A. The structure 200A in Figs. 42, 43, and 44 is in a state where the slat SL is slid in the Z direction from the structure 200A in Figs. 36, 37, 38, 39, 40, and 41. The left side view, right side view, and plan view showing the detailed configuration of the structure 200A in this case are omitted because they are the same as Figs. 39, 40, and 41.

[0204] Of the 14 slats SL, seven slats SL are housed in a case 213. The outside of the structure 200A and the passage 102 communicate with the inside I4 through the front side of the structure 200A. By changing the form of the front wall 210, the outside of the structure 200A and the passage 102 communicate with the inside I4 from a state in which the outside of the structure 200A and the passage 102 communicate with the inside I4. Since a working space is secured, a person or device performing agricultural work can perform agricultural work on a plant P through the front side of the structure 200A.

[0205] Fig. 45 is a perspective view showing the detailed configuration of the structure 200A. Fig. 46 is a front view showing the detailed configuration of the structure 200A. Fig. 47 is a rear view showing the detailed configuration of the structure 200A. The structure 200A in Figs. 45, 46, and 47 is in a state where the slat SL is slid in the Z direction from the structure 200A in Figs. 42, 43, and 44. The left side view, right side view, and plan view showing the detailed configuration of the structure 200A in this case are omitted because they are the same as Figs. 39, 40, and 41.

[0206] The fourteen slats SL are housed in a case 213. The outside of the structure 200A and the passage 102 communicate with the inside I4 through the front side of the structure 200A. Because a working space is secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 200A.

[0207] The state of the structure 200A in Figures 42, 43, and 44 is a state in which the slat SL is slid in the negative Z direction from the state of the structure 200A in Figures 45, 46, and 47. The state of the structure 200A in Figures 36, 37, 38, 39, 40, and 41 is a state in which the slat SL is slid in the negative Z direction from the state of the structure 200A in Figures 42, 43, and 44. By changing the state of the front wall 210, the state in which the outside of the structure 200A, the passage 102, and the inside I4 are communicated with each other is changed to a state in which the outside of the structure 200A, the passage 102, and the inside I4 are blocked from each other.

[0208] (3) Operation The operation of the equipment 2 when a person or a machine performs harvesting work will be described. Since the operation of the structure 200A and the operation of the structure 200B are similar, the operation of the structure 200A will be mainly described. FIG. 48 is a flowchart showing the operation of the equipment 2. Air heated by the air conditioner 11 is supplied to the inside I4 via the hose 115 and the first opening 221. The structure 200A is the same as the structure 200A in FIG. 36, FIG. 37, FIG. 38, FIG. 39, FIG. 40, and FIG. 41.

[0209] Fourteen slats SL cover the front side of the structure 200A, blocking the outside of the structure 200A and the passage 102 from the inside I4. The heated air supplied to the inside I4 does not easily flow to the outside of the structure 200A. The temperature of the inside I4 is maintained higher than the temperature of the space I6. Therefore, the inside I4 is in an environment suitable for growing plants P. The plants P are in a state suitable for harvesting. No working space is provided.

[0210] A person or device moves from the outside of the vinyl greenhouse 10 into the inside of the vinyl greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 200A. The person or device applies a force in the Z direction to one or more of the 14 slats SL. Because the slats SL are connected to adjacent slats SL, the force in the Z direction is transmitted to the 14 slats SL. Therefore, the 14 slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and slid in the Z direction (step S11).

[0211] As the slats SL are slid in the Z direction, the rightmost slat SL of the 14 slats SL is stored in the case 213. When the seven slats SL are stored in the case 213, the state of the structure 200A is changed to the state of the structure 200A in Figures 42, 43, and 44 (step S12). The state of the front wall 210 in Figure 37 is changed to the state of the front wall 210 in Figure 43. The person or device continues to apply a force in the Z direction to one or more slats SL.

[0212] As the slats SL slide in the Z direction, the fourteen slats SL are stored in the case 213. The state of the structure 200A is changed to the state of the structure 200A in Figures 45, 46, and 47 (step S13). The state of the front wall 110 in Figure 43 is changed to the state of the front wall 210 in Figure 46. The front side of the structure 200A communicates the outside of the structure 200A and the passage 102 with the inside I4. Now that a working space has been secured, a person or a device can perform harvesting work on the plant P. The person or a device starts harvesting work on the plant P.

[0213] When the harvesting work is completed, a person or a device applies a force in the negative Z direction to one or more slats SL stored in the case 213. Because the slats SL are connected to the other adjacent slats SL, the force in the negative Z direction is transmitted to the 14 slats SL. Therefore, the 14 slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and slid in the negative Z direction (step S14).

[0214] The slat SL is pulled out to the left of the case 213. When the seven slats SL are pulled out to the left from the case 213, the state of the structure 200A is changed to the state of the structure 200A in Figures 42, 43, and 44 (step S15). The state of the front wall 210 in Figure 46 is changed to the state of the front wall 210 in Figure 43. The person or device continues to apply a force in the negative Z direction to one or more slats SL. The fourteen slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and slid in the negative Z direction.

[0215] When the fourteen slats SL are pulled out to the left from the case 213, the state of the structure 200A is changed to the state of the structure 200A in Figures 36, 37, 38, 39, 40, and 41 (step S16). The state of the front wall 210 in Figure 43 is changed to the state of the front wall 210 in Figure 37. The front side of the structure 200A is covered by the fourteen slats SL. Therefore, the outside of the structure 200A and the passage 102 are blocked off from the inside I4.

[0216] The person or device moves to the outside of the greenhouse 10 via the passage 102 and the entrance / exit 101. The person or device operates the air conditioner 11 so that the air conditioner 11 stops heating and starts dehumidification. The supply of warm air from the hose 115 and the first opening 221 to the inside I4 is stopped. The air conditioner 11 supplies dehumidified air to the inside I4 via the hose 116 and the second opening 222. The humidity on the inside I4 decreases, and the humidity becomes lower than the outside of the structure 200A. Therefore, the inside I4 becomes an environment suitable for sowing work.

[0217] (4) Features (4-1) The variable structure further includes a third guide rail 211 provided substantially parallel to an internal floor F, and a fourth guide rail 212 facing the third guide rail 211 and provided substantially parallel to the floor F. The first component is guided and slid by the third guide rail 211 and the fourth guide rail 212, thereby changing the state of the first component.

[0218] Since the first component is guided by the third guide rail 211 and the fourth guide rail 212, the force received by the first component is unlikely to be dispersed in unspecified directions. The first component is efficiently slid in a direction substantially parallel to the floor F. Therefore, in the variable structure, the state of the first component can be easily changed by a person or a device.

[0219] (4-2) The variable structure has a supply section including a first opening 221 provided approximately vertically below the approximately vertical center of the variable structure, and a second opening 222 provided approximately vertically above the approximately vertical center of the variable structure, the first opening 221 being an opening for supplying heated air from the air conditioner 11 to the inside I4 and the inside I5, and the second opening 222 being an opening for supplying cooled air from the air conditioner 11 to the inside I4 and the inside I5.

[0220] In order to create an environment suitable for plant cultivation, the space in which the plants are grown may be heated and cooled. Heated air is lighter than unheated air. However, cooled air is heavier than uncooled air. Therefore, if heating and cooling are performed through the same opening, temperature unevenness may occur when at least one of heating and cooling is performed.

[0221] The variable structure is provided with a first opening 221 that supplies heated air to the inside I4 and the inside I5, and a second opening 222 that supplies cooled air to the inside I4 and the inside I5. Therefore, the variable structure makes it difficult for temperature unevenness to occur on the inside I4 and the inside I5 in the case of heating and cooling. Therefore, the variable structure makes the inside I4 and the inside I5 an environment more suitable for growing plants P.

[0222] (4-3) The variable structure has a supply section including a first opening 221 provided approximately vertically below the approximately vertical center of the variable structure, and a second opening 222 provided approximately vertically above the approximately vertical center of the variable structure, the first opening 221 being an opening for supplying humidified air from the air conditioner 11 to the insides I4 and I5, and the second opening 222 being an opening for supplying dehumidified air from the air conditioner 11 to the insides I4 and I5.

[0223] In order to create an environment suitable for plant cultivation, the space in which the plants are grown may be humidified and dehumidified. Humidified air is lighter than non-humidified air. However, dehumidified air is heavier than non-dehumidified air. Therefore, if humidification and dehumidification are performed through the same opening, humidity unevenness may occur when at least one of humidification and dehumidification is performed.

[0224] The variable structure is provided with a first opening 221 that supplies humidified air to the inside I4 and the inside I5, and a second opening 222 that supplies dehumidified air to the inside I4 and the inside I5. Therefore, the variable structure makes it difficult for humidity unevenness to occur on the inside I4 and the inside I5 in the case of humidification and dehumidification. Therefore, the variable structure makes the inside I4 and the inside I5 an environment more suitable for growing plants P.

[0225] (5) Variations Regarding the modified example of the second embodiment, the description will be omitted for the similarities to the second embodiment, and the description will be centered on the differences from the second embodiment.

[0243] <Third embodiment> (1) Overall structure The overall configuration of the facility 3 according to the third embodiment will be described. Hereinafter, the description of the similarities between the second and third embodiments will be omitted, and the differences between the second and third embodiments will be mainly described. FIG. 55 is a schematic diagram showing the overall configuration of the facility 3 according to the third embodiment. The facility 3 mainly includes a vinyl greenhouse 10 and an air conditioner 11.

[0244] (1-1) Plastic greenhouse A structure 300A and a structure 300B are mainly provided inside the vinyl greenhouse 10. The structures 300A and 300B divide the inside of the vinyl greenhouse 10 into an inside space I7 of the structure 300A, an inside space I8 of the structure 300B, and a space I9 outside the structures 300A and 300B and inside the vinyl greenhouse 10.

[0247] (2) Detailed configuration The detailed configurations of the structure 300A and the structure 300B will be described. The structure 300A is a variable structure whose state can be changed by the operation of the structure 300A. The structure 300B is a variable structure whose state can be changed by the operation of the structure 300B. The structures of the structure 300A and the structure 300B are substantially symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 300A is similar to that of the structure 300B. The structure and function of the structure 300A will be described below.

[0248] Fig. 56 is a perspective view showing the detailed configuration of the structure 300A. Fig. 57 is a front view showing the detailed configuration of the structure 300A. Fig. 58 is a rear view showing the detailed configuration of the structure 300A. Fig. 59 is a left side view showing the detailed configuration of the structure 300A. Fig. 60 is a right side view showing the detailed configuration of the structure 300A. Fig. 61 is a plan view showing the detailed configuration of the structure 300A. In Figs. 56, 57, 58, 59, 60, and 61, the plant P has finished growing.

[0249] The structure 300A mainly has a front wall 310, a third guide rail 311, a fourth guide rail 312, a left side wall 320, a right side wall 330, a rear wall 340, and a ceiling 350.

[0250] The third guide rail 311 is provided approximately parallel to the floor F. The third guide rail 311 includes two rows of rails aligned in the X direction and extending in the Z direction. Of the two rows of rails, the front rail is referred to as the "third front rail." Of the two rows of rails, the rear rail is referred to as the "third rear rail."

[0251] The fourth guide rail 312 faces the third guide rail 311 and is provided approximately parallel to the floor F. The fourth guide rail 312 includes two rows of rails aligned in the X direction and extending in the Z direction. Of the two rows of rails, the front rail is referred to as the "fourth front rail." Of the two rows of rails, the rear rail is referred to as the "fourth rear rail." The third front rail and the fourth front rail face each other. The third rear rail and the fourth rear rail face each other.

[0252] The front wall 310 is mainly composed of two slats SL. The two slats SL are approximately perpendicular to the floor F. The two slats SL are guided by the third guide rail 311 and the fourth guide rail 312 and can slide in the Z direction or the negative Z direction (the direction in which the third guide rail 311 and the fourth guide rail 312 extend). The state of the front wall 310 is changed by the two slats SL being guided by the third guide rail 311 and the fourth guide rail 312 and sliding.

[0253] Of the two slats SL that make up the front wall 310, the left slat SL is referred to as the "left slat SL" and the right slat SL is referred to as the "right slat SL". The left slat SL can move left and right by sliding between the third front rail and the fourth front rail. The right slat SL can move left and right by sliding between the third rear rail and the fourth rear rail. The two slats SL are not connected to each other and can be slid independently of each other. The two slats SL are arranged so that they do not overlap (collide with) each other even when moving left and right.

[0254] The front wall 310 is an example of a first component, and is erected substantially perpendicular to the floor F. The front wall 310 faces the passage 102.

[0255] The left side wall 320 faces the right side wall 330, and stands approximately perpendicular to the floor F. The left side wall 320 is in contact with the front wall 310, the rear wall 340, and the ceiling 350.

[0256] The right side wall 330 faces the left side wall 320, and stands substantially perpendicular to the floor F. The right side wall 330 is in contact with the front wall 310, the rear wall 340, and the ceiling 350.

[0257] The rear wall 340 faces the front wall 310 and stands approximately perpendicular to the floor F. The rear wall 340 contacts the left side wall 320, the right side wall 330, and the ceiling 350. The rear wall 340 is provided with an opening 341 that communicates with a hose. The rear wall 340 is also provided with an opening 342 that communicates with the outside of the structure 300A.

[0258] The opening 341 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the inside I7 through the opening 341. The opening 341 is provided substantially vertically below the substantially vertical center of the rear wall 340. In other words, the opening 341 is provided substantially vertically below the substantially vertical center of the structure 300A. The opening 341 is provided substantially to the left of the substantially Z-direction center of the structure 300A.

[0259] The opening 341 may be provided in any of the front wall 310, the left side wall 320, the right side wall 330, or the ceiling 350, instead of the rear wall 340. The opening 341 may be provided in any of the front wall 310, the left side wall 320, the right side wall 330, or the ceiling 350, in addition to the rear wall 340. The opening 341 may be provided approximately vertically above the approximately vertical center of the rear wall 340. The opening 341 may be provided to the right of the approximately Z-direction center of the structure 300A.

[0260] The opening 342 is an example of a discharge portion. The opening 342 is provided substantially vertically above the substantially vertical center of the rear wall 340. In other words, the opening 342 is provided substantially vertically above the substantially vertical center of the structure 300A. The opening 342 is provided substantially to the right of the substantially Z-direction center of the structure 300A.

[0261] The air in the inside I7 is discharged from the inside I7 to the outside of the structure 300A through the opening 342. For example, the opening 342 is connected to a hose (not shown) that is connected to the intake port of the air conditioner 11. The air in the inside I7 flows to the intake port of the air conditioner 11 through the opening 342 and the hose.

[0262] The opening 342 may be provided in any one of the front wall 310, the left side wall 320, the right side wall 330, and the ceiling 350, instead of the rear wall 340. The opening 342 may be provided in at least one of the front wall 310, the left side wall 320, the right side wall 330, and the ceiling 350, in addition to the rear wall 340. The opening 342 may be provided substantially vertically below the substantially vertical center of the rear wall 340. The opening 342 may be provided to the left of the substantially Z-direction center of the structure 300A. The opening 342 may be connected to a hose (not shown) that is connected to a location outside the vinyl greenhouse 10 other than the air inlet of the air conditioner 11.

[0263] The ceiling 350 faces the floor F, and is approximately parallel to the floor F and approximately horizontal. The ceiling 350 is in contact with the front wall 310, the left side wall 320, the right side wall 330, and the rear wall 340.

[0264] The area of ​​the floor F facing the ceiling 350 is surrounded by the front wall 310, the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350, forming an inside I7. Specifically, the front wall 310 surrounds the front side of the area of ​​the floor F where the plant P is grown. The left wall 320 surrounds the left side of the area of ​​the floor F where the plant P is grown. The right wall 330 surrounds the right side of the area of ​​the floor F where the plant P is grown. The rear wall 340 surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling 350 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0265] The inside I7 is isolated from the outside of the structure 300A and the passage 102 by the front wall 310, the left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350. The inside I7 is covered between the outside of the structure 300A and the passage 102 by the front wall 310, the left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350. It becomes difficult for people, equipment, and air to pass from the outside of the structure 300A and the passage 102 to the inside I7. Therefore, the air supplied to the inside I7 by the opening 341 does not easily flow from the inside I7 to the outside of the structure 300A. The air in the space I9 also does not easily flow to the inside I7. It is difficult for people or equipment to approach the inside I7. People or equipment cannot secure a working space.

[0266] A plant P is cultivated on the inside I7. A part of the beds F on the inside I7 stores soil (not shown) in which the plant P can be planted or nutrient solution (not shown) in which the plant P can be soaked. On the inside I7, the plant P is planted in soil or soaked in nutrient solution. Note that cultivating a plant P on the inside I7 does not mean that the plant P is always present on the inside I7. After the plant P is harvested, there may be cases where the plant P is not present on the inside I7. Also, there may be cases where the plant P is present on the inside I7, but the plant P cannot be seen with the naked eye on the inside I7 because it has just been planted.

[0267] Examples of the configurations of the left side wall 320, the right side wall 330, the rear wall 340, the ceiling 350, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0268] The front wall 310 (two slats SL), the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I9 is ​​transmitted to the inside I7. Because the front wall 310 (two slats SL), the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 are transparent or semi-transparent, the plant P on the inside I7 can be seen through from the outside of the structure 300A.

[0269] The depth of the structure 300A (in other words, the depth of the ceiling 350) is a value that ensures D35 and D36. D35 is the shortest distance in the X direction from the plant P to the front wall 310 when the plant P has finished growing. D35 is preferably 1 cm to 10 cm, but is not limited to this. D36 is the shortest distance in the negative X direction from the plant P to the rear wall 340 when the plant P has finished growing. D36 is preferably 1 cm to 10 cm, but is not limited to this.

[0270] The height of the structure 300A (in other words, the height between the front wall 310, the left side wall 320, the right side wall 330, and the rear wall 340) is a value that ensures D37. D37 is the shortest distance in the Y direction from the plant P to the ceiling 350 when the plant P has finished growing. D37 is preferably, but not limited to, 1 to 10 centimeters.

[0271] The width of the structure 300A (in other words, the width between the front wall 310, the rear wall 340, and the ceiling 350) is a value that ensures D38 and D39. D38 is the shortest distance in the negative Z direction from the plant P to the left side wall 320 when the plant P has finished growing. D38 is preferably, but not limited to, 1 centimeter to 10 centimeters. D39 is the shortest distance in the Z direction from the plant P to the right side wall 330 when the plant P has finished growing. D39 is preferably, but not limited to, 1 centimeter to 10 centimeters.

[0272] The left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350 are components whose configuration cannot be changed. The front wall 310 is a component whose configuration can be changed. Therefore, the structure 300A is a variable structure. Note that at least one of the left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350 may be a component whose configuration can be changed. Various configurations of the structure 300A will be described below.

[0273] Fig. 62 is a perspective view showing the detailed configuration of the structure 300A. Fig. 63 is a front view showing the detailed configuration of the structure 300A. Fig. 64 is a rear view showing the detailed configuration of the structure 300A. The state of the structure 300A in Figs. 62, 63, and 64 is a state in which the left slat SL is slid in the Z direction from the state of the structure 300A in Figs. 56, 57, 58, 59, 60, and 61. The left side view, right side view, and plan view showing the detailed configuration of the structure 300A in this case are omitted because they are the same as Figs. 59, 60, and 61.

[0274] The left slat SL has been slid in the Z direction, so that it is generally aligned with the right slat SL in the X direction. The inside I7 is communicated with the outside of the structure 300A and the passage 102 through the left front side of the structure 300A. By changing the configuration of the front wall 310, the outside of the structure 300A, the passage 102, and the inside I7 are changed from a state in which the outside of the structure 300A and the passage 102 are blocked from the inside I7 to a state in which the outside of the structure 300A and the passage 102 are communicated with the inside I7. Since the working space has been secured, a person or device performing agricultural work can perform agricultural work on the plants P through the front side of the structure 300A.

[0275] Fig. 65 is a perspective view showing the detailed configuration of the structure 300A. Fig. 66 is a front view showing the detailed configuration of the structure 300A. Fig. 67 is a rear view showing the detailed configuration of the structure 300A. The state of the structure 300A in Figs. 65, 66, and 67 is a state in which the right slat SL is slid in the negative Z direction from the state of the structure 300A in Figs. 56, 57, 58, 59, 60, and 61. The left side view, right side view, and plan view showing the detailed configuration of the structure 300A in this case are omitted because they are the same as Figs. 59, 60, and 61.

[0276] The right slat SL has been slid in the negative Z direction, so that it is generally aligned with the left slat SL in the X direction. The inside I7 is connected to the outside of the structure 300A and the passage 102 through the right front side of the structure 300A. By changing the configuration of the front wall 310, the state in which the outside of the structure 300A and the passage 102 are blocked from the inside I7 is changed to a state in which the outside of the structure 300A and the passage 102 are connected to the inside I7. Since the work space has been secured, a person or device performing agricultural work can perform agricultural work on the plants P through the front side of the structure 300A.

[0277] 56, 57, 58, 59, 60, and 61 are also forms in which the left slat SL has been slid in the negative Z direction from the forms of the structure 300A in Figures 62, 63, and 64. By changing the form of the front wall 310, the outside of the structure 300A and the passage 102 are changed from a state in which the outside of the structure 300A and the passage 102 are connected to the inside I7 to a state in which the outside of the structure 300A and the passage 102 are blocked from the inside I7.

[0278] 56, 57, 58, 59, 60, and 61 are also in a state where the right slat SL is slid in the Z direction from the state of the structure 300A in Figures 65, 66, and 67. By changing the state of the front wall 310, the outside of the structure 300A and the passage 102 are changed from a state in which the outside of the structure 300A and the passage 102 are connected to the inside I7 to a state in which the outside of the structure 300A and the passage 102 are blocked from the inside I7.

[0279] (3) Operation The operation of the equipment 3 when a person or a machine performs harvesting work will be described. Since the operation of the structure 300A and the operation of the structure 300B are similar, the operation of the structure 300A will be mainly described. Fig. 68 is a flowchart showing the operation of the equipment 3. Air heated by the air conditioner 11 is supplied to the inside I7 through the hose and the opening 341. The structure 300A is the same as that of the structure 300A shown in Figs. 56, 57, 58, 59, 60, and 61.

[0280] Since two slats SL cover the front side of the structure 300A, the outside of the structure 300A and the passage 102 are separated from the inside I7. The heated air supplied to the inside I7 does not easily flow to the outside of the structure 300A. The temperature of the inside I7 is maintained higher than the temperature of the space I9. Therefore, the inside I7 is in an environment suitable for growing the plant P. The plant P is in a state suitable for harvesting.

[0281] A person or device moves from the outside of the vinyl greenhouse 10 into the inside of the vinyl greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 300A. The person or device applies a force in the Z direction to the left slat SL of the two slats SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the Z direction. The left slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the Z direction (step S21).

[0282] Since the left slat SL has been slid in the Z direction, the left slat SL is generally aligned with the right slat SL in the X direction. The state of the structure 300A is changed to the state of the structure 300A in Figures 62, 63, and 64 (step S22). The state of the front wall 310 in Figure 57 is changed to the state of the front wall 310 in Figure 63. The left front side of the structure 300A communicates the outside of the structure 300A and the passage 102 with the inside I7. Since the working space has been secured, a person or a device can perform harvesting work on the plant P on the left side. A person or a device starts harvesting work on the plant P on the left side.

[0283] When the harvesting work on the plant P on the left side is completed, a person or a device applies a force in the negative Z direction to the left slat SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the negative Z direction. The left slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slid in the negative Z direction (step S23).

[0284] Because the left slat SL has been slid in the negative Z direction, the state of the structure 300A is changed to the state of the structure 300A in Figures 56, 57, 58, 59, 60, and 61 (step S24). The state of the front wall 310 in Figure 63 is changed to the state of the front wall 310 in Figure 57. Because the left front side of the structure 300A is covered by the left slat SL, the outside of the structure 300A and the passage 102 are blocked from the inside I7.

[0285] A person or device applies a force in the negative Z direction to the right slat SL of the two slats SL. Because the right slat SL and the left slat SL are independent of each other, only the right slat SL receives the force in the negative Z direction. The right slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the negative Z direction (step S25).

[0286] Since the right slat SL has been slid in the negative Z direction, the right slat SL is generally aligned with the left slat SL in the X direction. The state of the structure 300A is changed to that of the structure 300A in Figures 65, 66, and 67 (step S26). The state of the front wall 310 in Figure 57 is changed to that of the front wall 310 in Figure 66. The right front side of the structure 300A communicates the outside of the structure 300A and the passage 102 with the inside I7. Since the working space has been secured, a person or a device can perform harvesting work on the plant P on the right side. A person or a device starts harvesting work on the plant P on the right side.

[0287] When the harvesting work on the right-side plant P is completed, a person or a device applies a force in the Z direction to the right slat SL. Because the right slat SL and the left slat SL are independent of each other, only the right slat SL receives the force in the Z direction. The right slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the Z direction (step S27).

[0288] Because the right slat SL has been slid in the Z direction, the state of the structure 300A is changed to that of the structure 300A in Figures 56, 57, 58, 59, 60, and 61 (step S28). The state of the front wall 310 in Figure 66 is changed to that of the front wall 310 in Figure 57. Because the right front side of the structure 300A is covered by the right slat SL, the outside of the structure 300A and the passage 102 are blocked from the inside I7.

[0289] (4) Variations Regarding the modified example of the third embodiment, a description of the similarities to the third embodiment will be omitted and the differences from the third embodiment will be mainly described.

Specifically, the racks R are provided on the insides I7 and I8, and the plants P are cultivated on the racks R. The racks R are similar to those in the modified example 2B, and therefore a description thereof will be omitted.

[0295] The depth and width of the structure 300A of the modified example 3B are the same as those of the structure 300A of the modified example 3A, and therefore a description thereof will be omitted. The height of the structure 300A (in other words, the heights of the front wall 310, the left side wall 320, the right side wall 330, and the rear wall 340) is a value that ensures D45 (not shown).

Fig. 71 is a schematic diagram showing the overall configuration of the facility 3 according to the modified example 3C. In the inside I7 and the inside I8, a server SV is installed instead of cultivating a plant P. The work space is a space necessary for server work.

[0297] The depth of the structure 300A (in other words, the depth of the ceiling 350) is a value that ensures D46 (not shown) and D47 (not shown). D46 is the shortest distance in the X direction from the server SV to the front wall 310. D46 is preferably 5 to 20 centimeters, but is not limited to this. D47 is the shortest distance in the negative X direction from the server SV to the rear wall 340. D47 is preferably 15 to 40 centimeters, but is not limited to this.

[0298] The height of the structure 300A (in other words, the heights of the front wall 310, the left side wall 320, the right side wall 330, and the rear wall 340) is a value that ensures D48 (not shown). D48 is the shortest distance in the Y direction from the server SV to the ceiling 350. D48 is preferably, but not limited to, 5 to 20 centimeters.

[0300] (4-4) 3D Variation The structures 300A and 300B may be provided inside the warehouse 50 instead of inside the vinyl greenhouse 10. FIG. 72 is a schematic diagram showing the overall configuration of the facility 3 according to the modified example 3D. On the insides I7 and I8, instead of cultivating plants P, products G are stored. Specifically, racks R are provided on the insides I7 and I8, and products G are stored on the racks R. The racks R are similar to those in the modified example 2D, so a description thereof will be omitted. The work space is a space necessary for warehouse work.

[0301] The depth and width of the structure 300A are the same as those of the modified example 3A, and therefore will not be described. The height of the structure 300A (in other words, the heights of the front wall 310, left side wall 320, right side wall 330, and rear wall 340) is a value that ensures D51 (not shown). D51 is the shortest distance in the Y direction from the product G stored on the top platform 180 of the rack R to the ceiling 350. D51 is preferably, but not limited to, 5 to 10 centimeters.

[0302] (4-5) Variation 3E The structure 300A and the structure 300B may be provided inside the livestock barn 60 instead of inside the vinyl greenhouse 10. Fig. 73 is a schematic diagram showing the overall configuration of the facility 3 according to the modified example 3E.

Fig. 74 is a schematic diagram showing the overall configuration of the facility 3 according to the modified example 3F. In the insides I7 and I8, instead of cultivating plants P, aquatic organisms Q are cultivated. Specifically, an aquarium A is provided in the insides I7 and I8, and the aquatic organisms Q are cultivated in the water W stored in the aquarium A. The work space is a space necessary for the culture work.

[0305] The depth of the structure 300A is the depth of the tank A plus 5 cm to 30 cm, but is not limited to this. The width of the structure 300A is the width of the tank A plus 5 cm to 30 cm, but is not limited to this.

[0308] (1-1) Plastic greenhouse The interior of the vinyl greenhouse 10 is mainly provided with a structure 400A, a structure 400B, a structure 400C, and a structure 400D. The interior of the vinyl greenhouse 10 is divided into an inside I10 of the structure 400A, an inside I11 of the structure 400B, an inside I12 of the structure 400C, an inside I13 of the structure 400D, and a space I14 that is outside the structures 400A, 400B, 400C, and 400D and is inside the vinyl greenhouse 10. Details of the structures 400A, 400B, 400C, and 400D will be described later.

[0309] The facility 4 may include a greenhouse (a glass greenhouse, a plastic film greenhouse, etc.) instead of the vinyl greenhouse 10.

[0310] (1-2) Air conditioner The air conditioner 11 communicates with the inside I10 via a hose 111. The air conditioner 11 also communicates with the inside I11 via another hose (not shown), communicates with the inside I12 via another hose (not shown), and communicates with the inside I13 via another hose (not shown). Air conditioned by the air conditioner 11 is supplied to the insides I10, I11, I12, and I13 via the hoses 111, etc.

[0311] (2) Detailed configuration The detailed configurations of the structure 400A, the structure 400B, the structure 400C, and the structure 400D will be described. The structure 400A is a variable structure that can change the state of the structure 400A by the operation of the structure 400A. The structure 400B is a variable structure that can change the state of the structure 400B by the operation of the structure 400B. The structure 400C is a variable structure that can change the state of the structure 400C by the operation of the structure 400C. The structure 400D is a variable structure that can change the state of the structure 400D by the operation of the structure 400D.

[0312] The structure of the structure 400A and the structure of the structure 400B are approximately symmetrical with respect to a plane extending in the Y direction and the X direction. The structure of the structure 400A and the structure 400C are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction.

The function of the structure 400A, the function of the structure 400B, the function of the structure 400C, and the function of the structure 400D are similar. The structure and function of the structure 400A will be described below.

[0313] Fig. 76 is a perspective view showing the detailed configuration of the structure 400A. Fig. 77 is a front view showing the detailed configuration of the structure 400A. Fig. 78 is a rear view showing the detailed configuration of the structure 400A. Fig. 79 is a left side view showing the detailed configuration of the structure 400A. Fig. 80 is a right side view showing the detailed configuration of the structure 400A. Fig. 81 is a plan view showing the detailed configuration of the structure 400A. In Figs. 76, 77, 78, 79, 80, and 81, the plant P has finished growing.

[0314] The structure 400A mainly has a front wall 410, a left side wall 420, a right side wall 430, a rear wall 440, a ceiling 450, and a rotation axis AX.

[0315] The front wall 410 is an example of a first component, and is erected substantially perpendicular to the floor F. The front wall 410 faces the passage 102. An upper end portion of the front wall 410 is connected to a front end portion of the ceiling 450.

[0316] The left side wall 420 faces the right side wall 430, and stands approximately perpendicular to the floor F. The left side wall 420 is in contact with the front wall 410, the rear wall 440, and a ceiling 450. The left side wall 420 is provided with an opening 421 that communicates with the hose 111.

[0317] The opening 421 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the inside I10 through the opening 421. The opening 421 is provided substantially vertically below the substantially vertical center of the left side wall 420. In other words, the opening 421 is provided substantially vertically below the substantially vertical center of the structure 400A. The opening 421 is provided substantially rearward of the substantially X-direction center of the structure 400A.

[0318] The opening 421 may be provided in the front wall 410, the right wall 430, the rear wall 440, and the ceiling 450 instead of the left side wall 420. The opening 421 may be provided in the front wall 410, the right side wall 430, the rear wall 440, and the ceiling 450 in addition to the left side wall 420. The opening 421 may be provided substantially vertically above the substantially vertical center of the structure 400A. The opening 421 may be provided forward of the substantially X-direction center of the structure 400A.

[0319] The right side wall 430 faces the left side wall 420 and stands substantially perpendicular to the floor F. The right side wall 430 is in contact with the front wall 410, the rear wall 440, and the ceiling 450. The right side wall 430 is provided with an opening 431 that communicates with the outside of the structure 400A.

[0320] The opening 431 is an example of a discharge portion. The opening 431 is provided substantially vertically above the substantially vertical center of the right side wall 430. In other words, the opening 431 is provided substantially vertically above the substantially vertical center of the structure 400A. The opening 431 is provided substantially forward of the substantially X-direction center of the structure 400A.

[0321] The air in the inside I10 is discharged from the inside I10 to the outside of the structure 400A through the opening 431. For example, the opening 431 is connected to a hose (not shown) that is connected to the intake port of the air conditioner 11. The air in the inside I10 flows to the intake port of the air conditioner 11 through the opening 431 and the hose.

[0322] The opening 431 may be provided in any one of the front wall 410, the left wall 420, the rear wall 440, and the ceiling 450, instead of the right side wall 430. The opening 431 may be provided in at least one of the front wall 410, the left side wall 420, the rear wall 440, and the ceiling 450, in addition to the right side wall 430. The opening 431 may be provided substantially vertically below the center of the structure 400A in the substantially vertical direction. The opening 431 may be provided behind the center of the structure 400A in the substantially X direction. The opening 431 may be connected to a hose (not shown) that is connected to a location outside the vinyl greenhouse 10 other than the suction port of the air conditioner 11.

[0323] The rear wall 440 faces the front wall 410, and stands approximately perpendicular to the floor F. The rear wall 440 contacts the left side wall 420, the right side wall 430, and the ceiling 450. A rotating member 441 and a fixed member 442 are provided on the rear wall 440.

[0324] The rotating member 441 is a member for fixing the ceiling 450 in a rotated state. The rotating member 441 is provided at approximately the center of the rear wall 440 in the Z direction, and is provided on the front side of the rear wall 440. The rotating member 441 is provided rotatably on a plane extending in the Y direction and the Z direction, with the approximately center of the rotating member 441 in the Y direction and the approximately center in the Z direction as the center of rotation. Note that a plurality of rotating members 441 may be provided on the rear wall 440.

[0325] The fixing member 442 is a member for fixing the ceiling 450 in a rotated state. The fixing member 442 is provided at approximately the center of the rear wall 440 in the approximately horizontal direction, and is provided on the rear side of the rear wall 440. The fixing member 442 is fixed to the rear wall 440. The fixing member 442 is provided so as to face the rotating member 441. Note that a plurality of fixing members 442 may be provided on the rear wall 440.

[0326] The rotation axis AX is provided along the rear end of the ceiling 450 and is approximately parallel to the floor F.

[0327] The ceiling 450 faces the floor F, is approximately parallel to the floor F, and is approximately horizontal. The ceiling 450 is in contact with the front wall 410, the left side wall 420, the right side wall 430, and the rear wall 440. The ceiling 450 can be moved by rotating about a rotation axis AX. The ceiling 450 is provided rotatably on a plane extending in the X direction and the Y direction with the rotation axis AX as the center of rotation. The front end of the ceiling 450 is connected to the upper end of the front wall 410. Therefore, when the ceiling 450 is rotated about the rotation axis AX, the front wall 410 is also rotated together with the ceiling 450. This changes the state of the front wall 410.

[0328] The area of ​​the floor F facing the ceiling 450 is surrounded by the front wall 410, the left side wall 420, the right side wall 430, the rear wall 440, and the ceiling 450, forming the inside I10. Specifically, the front wall 410 surrounds the front side of the area of ​​the floor F where the plant P is grown. The left side wall 420 surrounds the left side of the area of ​​the floor F where the plant P is grown. The right side wall 430 surrounds the right side of the area of ​​the floor F where the plant P is grown. The rear wall 440 surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling 450 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0329] The inside I10 is separated from the outside of the structure 400A and the passage 102 by a front wall 410, a left side wall 420, a right side wall 430, a rear wall 440, and a ceiling 450. The space between the inside I10 and the outside of the structure 400A and the passage 102 is covered by a front wall 410, a left side wall 420, a right side wall 430, a rear wall 440, and a ceiling 450. It becomes difficult for people, equipment, and air to pass from the outside of the structure 400A and the passage 102 to the inside I10. Therefore, air supplied to the inside I10 by the opening 421 does not easily flow from the inside I10 to the outside of the structure 400A. Air in the space I14 also does not easily flow to the inside I10. It is difficult for people or equipment to approach the inside I10. People or equipment cannot secure a working space.

[0330] A plant P is cultivated on the inside I10. A part of the beds F on the inside I10 is filled with soil (not shown) in which the plant P can be planted or with nutrient solution (not shown) in which the plant P can be soaked. On the inside I10, the plant P is planted in soil or soaked in nutrient solution. Note that cultivating a plant P on the inside I10 does not mean that the plant P is always present on the inside I10. After the plant P is harvested, there may be cases where the plant P is not present on the inside I10. Also, there may be cases where the plant P is present on the inside I10, but the plant P cannot be seen with the naked eye on the inside I10 because it has just been planted.

[0331] Examples of configurations of front wall 410, left side wall 420, right side wall 430, rear wall 440, and ceiling 450 include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0332] The front wall 410, the left wall 420, the right wall 430, the rear wall 440, and the ceiling 450 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I14 is transmitted to the inside I10. Because the front wall 410, the left wall 420, the right wall 430, the rear wall 440, and the ceiling 450 are transparent or semi-transparent, the plant P on the inside I10 can be seen through from the outside of the structure 400A.

[0333] The depth of the structure 400A (in other words, the depth of the ceiling 450) is a value that ensures D52 and D53. D52 is the shortest distance in the X direction from the plant P to the front wall 410 when the plant P has finished growing. D52 is preferably 1 cm to 10 cm, but is not limited to this. D53 is the shortest distance in the negative X direction from the plant P to the rear wall 440 when the plant P has finished growing. D53 is preferably 1 cm to 10 cm, but is not limited to this.

[0334] The height of the structure 400A (in other words, the heights of the front wall 410, the left side wall 420, the right side wall 430, and the rear wall 440) is a value that ensures D54. D54 is the shortest distance in the Y direction from the plant P to the ceiling 450 when the plant P has finished growing. D54 is preferably, but not limited to, 1 to 10 centimeters.

[0335] The width of the structure 400A (in other words, the width between the front wall 410, the rear wall 440, and the ceiling 450) is a value that ensures D55 and D56. D55 is the shortest distance in the negative Z direction from the plant P to the left side wall 420 when the plant P has finished growing. D55 is preferably, but not limited to, 1 cm to 10 cm. D56 is the shortest distance in the Z direction from the plant P to the right side wall 430 when the plant P has finished growing. D56 is preferably, but not limited to, 1 cm to 10 cm.

[0336] The left side wall 420, the right side wall 430, and the rear wall 440 are components whose behavior cannot be changed. The front wall 410 and the ceiling 450 are components whose behavior can be changed. Therefore, the structure 400A is a variable structure. At least one of the left side wall 420, the right side wall 430, and the rear wall 440 may be a component whose behavior can be changed. For example, at least one of the left side wall 420 and the right side wall 430 may be connected to the ceiling 450. In this case, at least one of the left side wall 420 and the right side wall 430 connected to the ceiling 450 rotates along with the ceiling 450. Below, a description will be given of an embodiment of the structure 400A different from the embodiment of the structure 400A in Figures 76, 77, 78, 79, 80, and 81.

[0337] Fig. 82 is a perspective view showing a detailed configuration of the structure 400A. Fig. 83 is a front view showing a detailed configuration of the structure 400A. Fig. 84 is a rear view showing a detailed configuration of the structure 400A. Fig. 85 is a left side view showing a detailed configuration of the structure 400A. Fig. 86 is a right side view showing a detailed configuration of the structure 400A. Fig. 87 is a plan view showing a detailed configuration of the structure 400A.

[0338] The aspects of the structure 400A in Figures 82, 83, 84, 85, 86, and 87 are aspects in which the ceiling 450 has been rotated around a rotation axis AX from the aspects of the structure 400A in Figures 76, 77, 78, 79, 80, and 81. The ceiling 450 has been rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. Since the ceiling 450 has been rotated, the front wall 410 has also been rotated together with the ceiling 450.

[0339] The rotating member 441 is rotated slightly less than 90 degrees on a plane extending in the Y and Z directions, with the center of rotation being approximately the center of the rotating member 441 in the Y direction and approximately the center of the rotating member 441 in the Z direction. The ceiling 450 is sandwiched and fixed between the rotating member 441 on the front side of the ceiling 450 and a fixed member 442 on the rear side of the ceiling 450. As a result, the ceiling 450 and the front wall 410 are fixed in a rotated state about the rotation axis AX.

[0340] The inside I10 of the structure 400A is in a state of communication with the outside of the structure 400A and the passage 102 via the front side and the upper side. By changing the aspect of the ceiling 450 and the front wall 410, the state in which the outside of the structure 400A and the passage 102 are blocked from the inside I10 is changed to a state in which the outside of the structure 400A and the passage 102 are in communication with the inside I10. Since the work space is secured, a person or device performing agricultural work can perform agricultural work on the plant P via the front side and the upper side of the structure 400A.

[0341] 76, 77, 78, 79, 80, and 81 are also in a state where the ceiling 450 is rotated about the rotation axis AX from the state of the structure 400A in Figures 82, 83, 84, 85, 86, and 87. The ceiling 450 is rotated slightly less than 90 degrees on a plane extending in the X direction and the Y direction with the rotation axis AX as the rotation center. Since the ceiling 450 is rotated, the front wall 410 is also rotated together with the ceiling 450.

[0342] By changing the configuration of the ceiling 450 and the front wall 410, the outside of the structure 400A and the passage 102 are changed from being connected to the inside I10 to being blocked off from the outside of the structure 400A and the passage 102 and the inside I10.

[0343] (3) Operation The operation of the equipment 4 when a person or a device performs harvesting work will be described. The operation of the structure 400A, the structure 400B, the structure 400C, and the structure 400D is similar, so the operation of the structure 400A will be mainly described. FIG. 88 is a flowchart showing the operation of the equipment 4. Air heated by the air conditioner 11 is supplied to the inside I10 through the hose and the opening 421. The structure 400A is the same as that shown in FIG. 76, FIG. 77, FIG. 78, FIG. 79, FIG. 80, and FIG. 81.

[0344] A front wall 410 covers the front side of the structure 400A, and a ceiling 450 covers the upper side of the structure 400A. Therefore, the outside of the structure 400A and the passage 102 are separated from the inside I10. The heated air supplied to the inside I10 does not easily flow to the outside of the structure 400A. The temperature of the inside I10 is maintained higher than the temperature of the space I14. Therefore, the inside I10 is in an environment suitable for growing the plant P. The plant P is in a state suitable for harvesting.

[0345] A person or device moves from the outside of the vinyl greenhouse 10 into the inside of the vinyl greenhouse 10 through the entrance / exit 101. The person or device moves to the passage 102 on the front side of the structure 400A. The person or device applies forces in the Y direction and the negative X direction to at least one of the front wall 410 and the ceiling 450. The ceiling 450 receives the forces in the Y direction and the negative X direction and is rotated about the rotation axis AX. Specifically, the ceiling 450 is rotated in a plane extending in the X direction and the Y direction with the rotation axis AX as the rotation center. The front wall 410 connected to the ceiling 450 is also rotated together with the ceiling 450 (step S31).

[0346] As the ceiling 450 continues to rotate, it collides with the fixed member 442. The ceiling 450 that collides with the fixed member 442 receives a force in the X direction from the fixed member 442. This stops the rotation of the front wall 410 and the ceiling 450 (step S32). The ceiling 450 has been rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the center of rotation.

[0347] A person or a device rotates the rotating member 441. The rotating member 441 is rotated slightly less than 90 degrees on a plane extending in the Y and Z directions, with the center of rotation being approximately the center of the rotating member 441 in the Y direction and approximately the center of the rotating member 441 in the Z direction. The ceiling 450 is fixed by being sandwiched between the rotating member 441 on the front side of the ceiling 450 and the fixed member 442 on the rear side of the ceiling 450. The front wall 410 and the ceiling 450 are fixed in a state rotated around the rotation axis AX. The state of the structure 400A can be changed to the states shown in Figures 82, 83, 84, 85, 86, and 87 (step S33).

[0348] The front and upper sides of the structure 400A communicate the outside of the structure 400A and the passage 102 with the inside I10. Now that the working space has been secured, a person or a device can perform harvesting work on the plant P. The person or the device starts harvesting work on the plant P.

[0349] When the harvesting work is completed, a person or a device rotates the rotating member 441. The rotating member 441 rotates slightly less than 90 degrees on a plane extending in the Y direction and the Z direction, with the center of rotation being approximately the center of the rotating member 441 in the Y direction and approximately the center of the Z direction. The ceiling 450 is released from the state of being sandwiched between the rotating member 441 and the fixed member 442. The ceiling 450 receives a force in the negative Y direction due to gravity. Therefore, the ceiling 450 rotates on the axis of rotation AX. Specifically, the ceiling 450 rotates on a plane extending in the X direction and the Y direction, with the rotation axis AX as the center of rotation. In addition, the front wall 410 connected to the ceiling 450 is also rotated together with the ceiling 450 (step S34). Note that the person or the device may apply a force in the negative Y direction and the X direction to at least one of the front wall 410 and the ceiling 450.

[0350] As the front wall 410 and the ceiling 450 continue to rotate, the front wall 410 hits the floor F. The front wall 410 that hits the floor F receives a force in the Y direction from the floor F. This stops the rotation of the front wall 410 and the ceiling 450. The ceiling 450 has been rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the center of rotation.

[0351] The ceiling 450 covers the upper side of the structure 400A. The front wall 410 covers the front side of the structure 400A. The structure 400A is changed to the state shown in Figures 76, 77, 78, 79, 80, and 81 (step S35). The outside and the passage 102 of the structure 400A are blocked from the inside I10.

[0352] (4) Features The variable structure further includes a movable ceiling 450 that faces the internal floor F and is connected to the first component, and a rotation axis AX provided along an end of the ceiling 450. When the ceiling 450 is rotated about the rotation axis AX, the first component is also rotated together with the ceiling 450, thereby changing the state of the first component.

[0353] The first component is rotated along with the ceiling 450. The force applied to the first component is less likely to be dispersed in unspecified directions. The first component is moved in a fixed direction by the rotation axis AX. Therefore, the variable structure allows the state of the first component to be easily changed by a person or a device.

[0354] (5) Variations Regarding the modified example of the fourth embodiment, the description will be omitted for the similarities to the fourth embodiment, and the description will be centered on the differences from the fourth embodiment.

[0355] (5-1) Variation 4A The structures 400A, 400B, 400C, and 400D may be provided inside the mushroom cultivation facility 20 instead of inside the vinyl greenhouse 10. FIG. 89 is a schematic diagram showing the overall configuration of the equipment 4 according to the modified example 4A. Logs T (trees on which spawn of mushrooms M are planted) are placed on the insides I10, I11, I12, and I13. Mushrooms M are cultivated on the logs T. Note that the mushrooms M may be cultivated on mushroom bed blocks instead of the logs T. The work space is a space necessary for mushroom work.

[0356] The depth of the structure 400A (in other words, the depth of the ceiling 450) is a value that ensures D57 (not shown) and D58 (not shown). D57 is the shortest distance in the X direction from the log T and the mushrooms M in a finished state to the front wall 410. D57 is preferably 1 cm to 10 cm, but is not limited to this. D58 is the shortest distance in the negative X direction from the log T and the mushrooms M in a finished state to the rear wall 440. D58 is preferably 1 cm to 10 cm, but is not limited to this.

[0357] The height of structure 400A (in other words, the heights of front wall 410, left side wall 420, right side wall 430, and rear wall 440) is a value that ensures D59 (not shown). D59 is the shortest distance in the Y direction from logs T and fully grown mushrooms M to ceiling 450. D59 is preferably, but not limited to, 1 to 10 centimeters.

[0373] <Fifth embodiment> (1) Overall structure The overall configuration of the facility 5 according to the fifth embodiment will be described. Hereinafter, the description of the similarities between the third and fifth embodiments will be omitted, and the differences between the third and fifth embodiments will be mainly described. FIG. 95 is a schematic diagram showing the overall configuration of the facility 5 according to the fifth embodiment. The facility 5 mainly includes a vinyl greenhouse 10 and an air conditioner 11.

[0374] (1-1) Plastic greenhouse A structure 500A and a structure 500B are mainly provided inside the vinyl greenhouse 10. The structures 500A and 500B divide the inside of the vinyl greenhouse 10 into an inside I15 of the structure 500A, an inside I16 of the structure 500B, and a space I17 outside the structures 500A and 500B and inside the vinyl greenhouse 10. Details of the structures 500A and 500B will be described later.

[0375] The facility 5 may include a greenhouse (a glass greenhouse, a plastic film greenhouse, etc.) instead of the vinyl greenhouse 10.

[0376] (1-2) Air conditioner The air conditioner 11 communicates with the inside I15 through a hose (not shown) and communicates with the inside I16 through another hose (not shown). Air conditioned by the air conditioner 11 is supplied to the inside I15 and the inside I16 through the hose or the like.

[0377] (2) Detailed configuration The detailed configurations of the structure 500A and the structure 500B will be described. The structure 500A is a variable structure that can change the state of the structure 500A by the operation of the structure 500A. The structure 500B is a variable structure that can change the state of the structure 500B by the operation of the structure 500B. The structures of the structure 500A and the structure 500B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 500A is similar to that of the structure 500B. The structure and function of the structure 500A will be described below.

[0378] Fig. 96 is a perspective view showing the detailed configuration of the structure 500A. Fig. 97 is a front view showing the detailed configuration of the structure 500A. Fig. 98 is a rear view showing the detailed configuration of the structure 500A. Fig. 99 is a left side view showing the detailed configuration of the structure 500A. Fig. 100 is a right side view showing the detailed configuration of the structure 500A. Fig. 101 is a plan view showing the detailed configuration of the structure 500A. In Figs. 96, 97, 98, 99, 100, and 101, the plant P has finished growing.

[0379] The structure 500A mainly has a front wall 510, a third guide rail 511, a fourth guide rail 512, and a ceiling 550.

[0380] The third guide rail 511 is provided approximately parallel to the floor F. The left and right ends of the third guide rail 511 are fixed to the vertical wall V of the vinyl greenhouse 10. The third guide rail 511 includes two rows of rails aligned in the X direction and extending in the Z direction. Of the two rows of rails, the front rail is referred to as the "third front rail." Of the two rows of rails, the rear rail is referred to as the "third rear rail."

[0381] The fourth guide rail 512 faces the third guide rail 511 and is provided approximately parallel to the floor F. The left and right ends of the fourth guide rail 512 are fixed to the vertical wall V of the vinyl greenhouse 10. The fourth guide rail 512 includes two rows of rails aligned in the X direction and extending in the Z direction. Of the two rows of rails, the front rail is referred to as the "fourth front rail." Of the two rows of rails, the rear rail is referred to as the "fourth rear rail." The third front rail and the fourth front rail face each other. The third rear rail and the fourth rear rail face each other.

[0382] The front wall 510 is mainly composed of two slats SL. The two slats SL are approximately perpendicular to the floor F. The two slats SL are guided by the third guide rail 511 and the fourth guide rail 512 and can slide in the Z direction or the negative Z direction (the direction in which the third guide rail 511 and the fourth guide rail 512 extend). The state of the front wall 510 is changed by the two slats SL being guided by the third guide rail 511 and the fourth guide rail 512 and sliding.

[0383] Of the two slats SL that constitute the front wall 510, the left slat SL is referred to as the "left slat SL" and the right slat SL is referred to as the "right slat SL". The left slat SL can move left and right by sliding between the third front rail and the fourth front rail. The right slat SL can move left and right by sliding between the third rear rail and the fourth rear rail. The two slats SL are not connected to each other and can be slid independently of each other. The two slats SL are arranged so that they do not overlap (collide with) each other even when moving left and right.

[0384] The front wall 510 is an example of a first component, and is erected approximately perpendicular to the floor F. The front wall 510 faces the aisle 102. The left and right ends of the front wall 510 may contact the vertical wall V. In other words, the left end of the left slat SL may contact the vertical wall V. The right end of the right slat SL may contact the vertical wall V.

[0385] The ceiling 550 faces the floor F, is approximately parallel to the floor F, and is approximately horizontal. The ceiling 550 is in contact with the front wall 310. The left end, right end, and rear end of the ceiling 550 are fixed to the vertical wall V. The ceiling 550 is provided with an opening 551 that communicates with a hose. The ceiling 550 is also provided with an opening 552 that communicates with the outside of the structure 500A.

[0386] The opening 551 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the inside I15 through the opening 551. The opening 551 is provided to the left of the center of the structure 500A in the approximately Z direction. The opening 551 is also provided behind the center of the structure 500A in the approximately X direction.

[0387] The opening 551 may be provided in the front wall 510 instead of the ceiling 550. The opening 551 may be provided in the front wall 510 in addition to the ceiling 550. The opening 551 may be provided to the right of the approximate center of the structure 500A in the Z direction. The opening 551 may be provided forward of the approximate center of the structure 500A in the X direction.

[0388] The opening 552 is an example of a discharge portion. The opening 552 is provided to the right of the center of the structure 500A in the Z direction. The opening 552 is also provided in front of the center of the structure 500A in the X direction.

[0389] The air in the inside I15 is discharged from the inside I15 to the outside of the structure 500A through the opening 552. For example, the opening 552 is connected to a hose (not shown) that is connected to the intake port of the air conditioner 11. The air in the inside I15 flows to the intake port of the air conditioner 11 through the opening 552 and the hose.

[0390] The opening 552 may be provided in the front wall 510 instead of the ceiling 550. The opening 552 may be provided in the front wall 510 in addition to the ceiling 550. The opening 552 may be provided to the left of the approximate center of the structure 500A in the Z direction. The opening 552 may be provided behind the approximate center of the structure 500A in the X direction.

[0391] The area of ​​the floor F where the plant P is grown is surrounded by the front wall 510, the ceiling 550, and the vertical wall V of the vinyl greenhouse 10, thereby forming an inside I15. Specifically, the front wall 510 surrounds the front side of the area of ​​the floor F where the plant P is grown. The vertical walls V surround the left side, right side, and rear side of the area of ​​the floor F where the plant P is grown. The ceiling 550 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0392] The inside I15 is isolated from the outside of the structure 500A and the passage 102 by the front wall 510, the ceiling 550, and the vertical wall V. The inside I15, the outside of the structure 500A, and the passage 102 are covered by the front wall 510, the ceiling 550, and the vertical wall V. It becomes difficult for people, equipment, and air to pass from the outside of the structure 500A and the passage 102 to the inside I15. Therefore, the air supplied to the inside I15 by the opening 551 does not easily flow from the inside I15 to the outside of the structure 500A. The air in the space I17 also does not easily flow to the inside I15. It is difficult for people or equipment to approach the inside I15. People or equipment cannot secure a working space.

[0393] A plant P is cultivated on the inside I15. Some of the beds F on the inside I15 are filled with soil (not shown) in which the plant P can be planted or with nutrient solution (not shown) in which the plant P can be soaked. On the inside I15, the plant P is planted in soil or soaked in nutrient solution. Note that cultivating a plant P on the inside I15 does not mean that the plant P is always present on the inside I15. After the plant P is harvested, there may be cases where the plant P is not present on the inside I15. Also, there may be cases where the plant P is present on the inside I15, but the plant P cannot be seen with the naked eye on the inside I15 because it has just been planted.

[0394] Examples of configurations of the ceiling 550 and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0395] The front wall 510 (two slats SL) and the ceiling 550 include transparent or semi-transparent vinyl, glass, or plastic film so that the light of the lighting in the space I17 is transmitted to the inside I15. Because the front wall 510 (two slats SL) and the ceiling 550 are transparent or semi-transparent, the plant P on the inside I15 can be seen through from the outside of the structure 500A.

[0396] The depth of the structure 500A (in other words, the depth of the ceiling 550) is a value that ensures D72. D72 is the shortest distance in the X direction from the plant P to the front wall 510 when the plant P has finished growing. D72 is preferably, but not limited to, 1 to 10 centimeters.

[0397] The height of the structure 500A (in other words, the height of the front wall 510) is a value that ensures D73. D73 is the shortest distance in the Y direction from the plant P to the ceiling 550 when the plant P has finished growing. D73 is preferably, but not limited to, 1 to 10 centimeters.

[0398] The width of the structure 500A (in other words, the width between the front wall 510 and the ceiling 550) is the same as the width inside the vinyl greenhouse 10.

[0399] The ceiling 550 is a component that cannot be changed. The front wall 510 is a component that can be changed. Therefore, the structure 500A is a variable structure. The ceiling 550 may be a component that can be changed.

[0400] The structure 500A does not need to include a ceiling 550. In this case, the upper end of the front wall 510 is fixed in contact with the ceiling of the vinyl greenhouse 10. The area of ​​the floor F where the plant P is cultivated is surrounded by the front wall 510, the vertical wall V of the vinyl greenhouse 10, and the ceiling of the vinyl greenhouse 10, thereby forming an inside I15. Specifically, the front wall 510 surrounds the front side of the area of ​​the floor F where the plant P is cultivated. The vertical wall V surrounds the left side, right side, and rear side of the area of ​​the floor F where the plant P is cultivated. The ceiling of the vinyl greenhouse 10 surrounds the upper side of the area of ​​the floor F where the plant P is cultivated.

[0401] The structure 500A may have any one of a left side wall, a right side wall, and a rear wall. The area of ​​the floor F where the plant P is cultivated is surrounded by the front wall 510, the vertical wall V of the vinyl greenhouse 10, and any one of the left side wall, the right side wall, and the rear wall, thereby forming an inside I15.

[0402] Various aspects of the structure 500A will be described below. FIG. 102 is a perspective view showing the detailed configuration of the structure 500A. FIG. 103 is a front view showing the detailed configuration of the structure 500A. FIG. 104 is a rear view showing the detailed configuration of the structure 500A. The aspects of the structure 500A in FIGS. 102, 103, and 104 are aspects in which the left slat SL is slid in the Z direction from the aspects of the structure 500A in FIGS. 96, 97, 98, 99, 100, and 101. In this case, the left side view, right side view, and plan view showing the detailed configuration of the structure 500A are omitted because they are the same as those in FIGS. 99, 100, and 101.

[0403] The left slat SL has been slid in the Z direction, so that it is generally aligned with the right slat SL in the X direction. The inside I15 is connected to the outside of the structure 500A and the passage 102 through the left front side of the structure 500A. The state in which the outside of the structure 500A and the passage 102 are blocked from the inside I15 has been changed to a state in which the outside of the structure 500A and the passage 102 are connected to the inside I15 by changing the mode of the front wall 510. Since the working space has been secured, a person or device performing agricultural work can perform agricultural work on a plant P through the front side of the structure 500A.

[0404] Fig. 105 is a perspective view showing the detailed configuration of the structure 500A. Fig. 106 is a front view showing the detailed configuration of the structure 500A. Fig. 107 is a rear view showing the detailed configuration of the structure 500A. The structure 500A in Figs. 105, 106, and 107 is in a state where the right slat SL is slid in the negative Z direction from the structure 500A in Figs. 96, 97, 98, 99, 100, and 101. The left side view, right side view, and plan view showing the detailed configuration of the structure 500A in this case are omitted because they are the same as Figs. 99, 100, and 101.

[0405] The right slat SL is slid in the negative Z direction, so that it is generally aligned with the left slat SL in the X direction. The inside I15 is communicated with the outside of the structure 500A and the passage 102 through the right front side of the structure 500A. By changing the form of the front wall 510, the outside of the structure 500A, the passage 102, and the inside I15 are changed from a state in which the outside of the structure 500A, the passage 102, and the inside I15 are blocked to a state in which the outside of the structure 500A, the passage 102, and the inside I15 are communicated with each other. Since the working space is secured, a person or device performing agricultural work can perform agricultural work on a plant P through the front side of the structure 500A.

[0406] 96, 97, 98, 99, 100, and 101 are also in a state where the left slat SL is slid in the negative Z direction from the state of the structure 500A in Figures 102, 103, and 104. By changing the state of the front wall 510, the outside of the structure 500A and the passage 102 are changed from a state in which the outside of the structure 500A and the passage 102 are connected to the inside I15 to a state in which the outside of the structure 500A and the passage 102 are blocked from the inside I15.

[0407] 96, 97, 98, 99, 100, and 101 are also in a state where the right slat SL is slid in the Z direction from the state of the structure 500A in Figures 105, 106, and 107. By changing the state of the front wall 510, the outside of the structure 500A, the passage 102, and the inside I15 are changed from a state in which they are connected to each other to a state in which they are blocked from each other.

[0408] (3) Operation The operation of the equipment 5 when a person or a machine performs harvesting work will be described. Since the operation of the structure 500A and the operation of the structure 500B are similar, the operation of the structure 500A will be mainly described. FIG. 108 is a flowchart showing the operation of the equipment 5. Air heated by the air conditioner 11 is supplied to the inside I15 through the hose and the opening 551. The structure 500A is the same as the structure 500A shown in FIG. 96, FIG. 97, FIG. 98, FIG. 99, FIG. 100, and FIG. 101.

[0409] Since the two slats SL cover the front side of the structure 500A, the outside of the structure 500A and the passage 102 are separated from the inside I15. The heated air supplied to the inside I15 does not easily flow to the outside of the structure 500A. The temperature of the inside I15 is maintained higher than the temperature of the space I17. Therefore, the inside I15 is in an environment suitable for growing the plant P. The plant P is in a state suitable for harvesting.

[0410] A person or device moves from the outside of the vinyl greenhouse 10 into the inside of the vinyl greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 500A. The person or device applies a force in the Z direction to the left slat SL of the two slats SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the Z direction. The left slat SL is guided by the third guide rail 511 and the fourth guide rail 512 and slid in the Z direction (step S41).

[0411] Since the left slat SL has been slid in the Z direction, the left slat SL is generally aligned with the right slat SL in the X direction. The state of the structure 500A is changed to the state of the structure 500A in Figures 102, 103, and 104 (step S42). The state of the front wall 510 in Figure 97 is changed to the state of the front wall 510 in Figure 103. The left front side of the structure 500A communicates the outside of the structure 500A and the passage 102 with the inside I15. Since the working space has been secured, a person or a device can perform harvesting work on the plant P on the left side. A person or a device starts harvesting work on the plant P on the left side.

[0412] When the harvesting work on the plant P on the left side is completed, a person or a device applies a force in the negative Z direction to the left slat SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the negative Z direction. The left slat SL is guided by the third guide rail 511 and the fourth guide rail 512 and slid in the negative Z direction (step S43).

[0413] Since the left slat SL is slid in the negative Z direction, the state of the structure 500A is changed to the state of the structure 500A in Figures 96, 97, 98, 99, 100, and 101 (step S44). The state of the front wall 510 in Figure 103 is changed to the state of the front wall 510 in Figure 97. Since the left front side of the structure 500A is covered by the left slat SL, the outside of the structure 500A and the passage 102 are blocked from the inside I15.

[0414] A person or device applies a force in the negative Z direction to the right slat SL of the two slats SL. Because the right slat SL and the left slat SL are independent of each other, only the right slat SL receives the force in the negative Z direction. The right slat SL is guided by the third guide rail 511 and the fourth guide rail 512 and slides in the negative Z direction (step S45).

[0415] Since the right slat SL has been slid in the negative Z direction, the right slat SL is generally aligned with the left slat SL in the X direction. The state of the structure 500A is changed to that of the structure 500A in Figures 105, 106, and 107 (step S46). The state of the front wall 510 in Figure 97 is changed to that of the front wall 510 in Figure 106. The right front side of the structure 500A communicates the outside of the structure 500A and the passage 102 with the inside I15. Since the working space has been secured, a person or a device can perform harvesting work on the plant P on the right side. The person or a device starts harvesting work on the plant P on the right side.

[0416] When the harvesting work on the right-side plant P is completed, a person or a device applies a force in the Z direction to the right slat SL. Because the right slat SL and the left slat SL are independent of each other, only the right slat SL receives the force in the Z direction. The right slat SL is guided by the third guide rail 511 and the fourth guide rail 512 and slides in the Z direction (step S47).

[0417] Since the right slat SL has been slid in the Z direction, the state of the structure 500A is changed to that of the structure 500A in Figures 96, 97, 98, 99, 100, and 101 (step S48). The state of the front wall 510 in Figure 106 is changed to that of the front wall 510 in Figure 97. Since the right front side of the structure 500A is covered by the right slat SL, the outside of the structure 500A and the passage 102 are blocked from the inside I15.

[0418] (4) Features The convertible structure is formed by the inner side I15 and the inner side I16 enclosing at least the first component and / or the vertical wall V of the other structure and / or the ceiling of the other structure, an area of ​​the internal floor F in which the plants P are grown.

[0419] Because the vertical walls V of the other structure enclose the area of ​​floor F, the variable structure can enclose the area of ​​floor F with fewer components. Therefore, the variable structure can achieve energy savings in cultivating the plant P with fewer components, and can reduce the cost of cultivating the plant P.

[0420] (5) Variations Regarding the modified example of the fifth embodiment, the description will be omitted for the similarities to the fifth embodiment, and the description will be centered on the differences from the fifth embodiment.
