[Modes for carrying out the invention]

[0022] <Current situation> In recent years, structures have been used to cultivate plants or mushrooms, raise livestock, cultivate aquatic organisms, store goods, or install servers. To maintain a specific environment (temperature, humidity, etc.) inside these structures where plants or mushrooms, livestock, aquatic organisms, goods, and servers reside, air conditioning is provided for the interior of the structure. This has led to the problem that a large amount of energy is used for air conditioning inside the structure. The following describes an example of a variable structure that contributes to solving the above problem.

[0023] In the following embodiments, "front" means the X direction, "back" means the negative X direction, "left" means the negative Z direction, "right" means the Z direction, "down" means the negative Y direction, and "up" means the Y direction. Depth is the length in the X direction. Width is the length in the Z direction. Height is the distance in the Y direction from the floor F.

[0024] In the following embodiments, the floor is approximately horizontal. Therefore, if it is approximately perpendicular to the floor, it is approximately vertical. If it is approximately parallel to the floor, it is approximately horizontal. The perspective view is a view from diagonally above. The front view is a view from the front. The rear view is a view from the rear. The left side view is a view from the left. The right side view is a view from the right. The plan view is a view from above.

[0025] In the following embodiments, the structure includes buildings and structures. A building is a structure fixed to the land that has a roof and columns or walls. A structure is an artificial object fixed to the land.

[0026] In the following embodiments, the planar components may be curved components that cover the entire plane or a portion thereof. Blocking includes not only complete obstruction but also difficulty in passing through. For example, blocking A and B includes making it difficult to pass from B to A by covering the space between A and B with a wall.

[0027] <First Embodiment> (1) Overall structure The overall configuration of Equipment 1 according to the first embodiment will now be described. Figure 1 is a schematic diagram showing the overall configuration of Equipment 1. Equipment 1 mainly consists of a greenhouse 10 and an air conditioner 11.

[0028] (1-1) Greenhouse A greenhouse 10 is a structure in which a frame is assembled and the top is covered with plastic sheeting or similar material, for the purpose of cultivating plants P. Plants P are cultivated inside the greenhouse 10.

[0029] The interior of the greenhouse 10 mainly consists of structure 100A and structure 100B. Structures 100A and 100B divide the interior of the greenhouse 10 into three areas: the area inside structure 100A I1, the area inside structure 100B I2, and the area outside structures 100A and 100B which is the interior of the greenhouse 10 I3. Details of structures 100A and 100B will be described later. The greenhouse 10 mainly has an entrance / exit 101, a passageway 102, and one or more lights (not shown).

[0030] Furthermore, facility 1 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 10. Also, the vinyl greenhouse 10 may or may not be a building.

[0031] (1-1-1) Entrance / exit The entrance / exit 101 is an entrance for people or equipment that will be performing agricultural work to move from the outside of the greenhouse 10 to the inside of the greenhouse 10. The entrance / exit 101 is also an exit for people or equipment that have performed agricultural work to move from the inside of the greenhouse 10 to the outside of the greenhouse 10. The entrance / exit 101 may be a structure that can be opened and closed (opening / closing opening) or a structure that is open (opening). The greenhouse 10 may have multiple entrances / exits 101.

[0032] Agricultural work refers to work performed on plants P by people or equipment. Examples of agricultural work include sowing, which is the work of planting seeds or seedlings of plants P; cultivation, which is the work performed for the growth of plants P (watering, spraying pesticides, pruning, fertilizing, pest control, etc.); harvesting, which is the work of harvesting all or part of plants P; soil work, which is the work of preparing the soil or tilling it; hydroponic work, which is the work of storing or changing nutrient solutions; and other agricultural work.

[0033] (1-1-2) Passageway Passageway 102 is a passageway used by people or equipment when agricultural work is carried out, and is an outside passageway of structures 100A and 100B.

[0034] (1-2) Air conditioner The air conditioner 11 provides air conditioning for inner chambers I1 and I2. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. The air conditioner 11 is connected to inner chamber I1 by a hose 111. The air conditioner 11 is also connected to inner chamber I2 by a different hose (not shown) from hose 111. The air conditioned by the air conditioner 11 is supplied to inner chambers I1 and I2 via hose 111, etc.

[0035] Furthermore, the location where the air conditioner 11 is installed is not limited to the outside of the greenhouse 10. The air conditioner 11 may be installed in at least one of the following spaces: the inner space I1, the inner space I2, and the space I3.

[0036] (2) Detailed configuration The detailed configurations of structures 100A and 100B will now be described. Structure 100A is a variable structure whose configuration can be changed by the operation of structure 100A. Structure 100B is a variable structure whose configuration can be changed by the operation of structure 100B. A variable structure is a structure whose configuration can be changed. The structure of structure 100A and the structure of structure 100B are substantially symmetric with respect to the planes extending in the Y and Z directions. The functions of structure 100A and structure 100B are the same. The structure and function of structure 100A will be described below.

[0037] Figure 2 is a perspective view showing the detailed configuration of structure 100A. Figure 3 is a front view showing the detailed configuration of structure 100A. Figure 4 is a rear view showing the detailed configuration of structure 100A. Figure 5 is a left side view showing the detailed configuration of structure 100A. Figure 6 is a right side view showing the detailed configuration of structure 100A. Figure 7 is a top view showing the detailed configuration of structure 100A. In Figures 2, 3, 4, 5, 6, and 7, plant P is in a state where it has finished growing.

[0038] Structure 100A mainly consists of a front wall 110, a first guide rail 112, a second guide rail 113, a case 114, a left side wall 120, a right side wall 130, a rear wall 140, and a ceiling 150.

[0039] The first guide rail 112 is installed approximately perpendicular to the floor F. The second guide rail 113 is installed opposite the first guide rail 112 and approximately perpendicular to the floor F.

[0040] The front wall 110 is mainly composed of multiple slats SL. For example, the front wall 110 is mainly composed of nine slats SL. The slats SL are substantially perpendicular to the floor F. The slats SL are connected to other adjacent slats SL. The slats SL are guided by the first guide rail 112 and the second guide rail 113 and can slide in the Y direction or the negative Y direction (the direction in which the first guide rail 112 and the second guide rail 113 extend). The appearance of the front wall 110 is changed by the sliding of the slats SL guided by the first guide rail 112 and the second guide rail 113.

[0041] The front wall 110 is an example of the first component and is erected approximately perpendicular to the floor F. The front wall 110 faces the passageway 102.

[0042] Case 114 is provided above the front wall 110 and behind the first guide rail 112 and the second guide rail 113. Case 114 accommodates the slats SL that are slid in the Y direction. Case 114 is provided so as to accommodate all of the slats SL that make up the front wall 110. Case 114 may also be provided below the front wall 110.

[0043] The left wall 120 faces the right wall 130 and is erected approximately perpendicular to the floor F. The left wall 120 is in contact with the front wall 110, the rear wall 140, and the ceiling 150. The left wall 120 is provided with an opening 121 that communicates with the hose 111.

[0044] The opening 121 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the interior I1 through the opening 121. The opening 121 is located approximately vertically below the approximate vertical center of the left wall 120. In other words, the opening 121 is located approximately vertically below the approximate vertical center of the structure 100A. The opening 121 is located behind the approximate X-direction center of the structure 100A.

[0045] The opening 121 may be provided in the front wall 110, the right wall 130, the rear wall 140, or the ceiling 150 instead of the left wall 120. The opening 121 may also be provided in at least one of the front wall 110, the right wall 130, the rear wall 140, or the ceiling 150, in addition to the left wall 120. The opening 121 may be provided approximately vertically above the approximate vertical center of the structure 100A. The opening 121 may also be provided in front of the approximate X-direction center of the structure 100A.

[0046] The right-side wall 130 faces the left-side wall 120 and is erected approximately perpendicular to the floor F. The right-side wall 130 is in contact with the front wall 110, the rear wall 140, and the ceiling 150. The right-side wall 130 is provided with an opening 131 that communicates with the outside of the structure 100A.

[0047] The opening 131 is an example of a discharge section. The opening 131 is provided in the right-side wall 130, which is opposite the left-side wall 120 where the opening 121 is provided. The opening 131 is provided approximately vertically above the approximate vertical center of the right-side wall 130. In other words, the opening 131 is provided approximately vertically above the approximate vertical center of the structure 100A. The opening 131 is provided in front of the approximate X-direction center of the structure 100A.

[0048] The air inside I1 is discharged from inside I1 to the outside of the structure 100A through the opening 131. For example, the opening 131 is connected to a hose (not shown) that is connected to the intake port of the air conditioner 11. The air inside I1 flows to the intake port of the air conditioner 11 via the opening 131 and the hose.

[0049] The opening 131 may be provided in the front wall 110, the left wall 120, the rear wall 140, or the ceiling 150 instead of the right wall 130. The opening 131 may also be provided in at least one of the front wall 110, the left wall 120, the rear wall 140, or the ceiling 150, in addition to the right wall 130. The opening 131 may be provided approximately vertically below the approximate vertical center of the structure 100A. The opening 131 may be provided behind the approximate X-direction center of the structure 100A. The opening 131 may be connected to a hose (not shown) that communicates with a location outside the greenhouse 10 other than the air intake of the air conditioner 11.

[0050] The rear wall 140 faces the front wall 110 and is erected approximately perpendicular to the floor F. The rear wall 140 is in contact with the left wall 120, the right wall 130, and the ceiling 150.

[0051] The ceiling 150 is opposite the floor F, is approximately parallel to the floor F, and is approximately horizontal. The ceiling 150 is in contact with the front wall 110, the left wall 120, the right wall 130, and the rear wall 140.

[0052] The area of ​​floor F facing the ceiling 150 is enclosed by the front wall 110, the left wall 120, the right wall 130, the rear wall 140, and the ceiling 150, thereby forming the interior I1. Specifically, the front wall 110 encloses the front side of the area of ​​floor F where plants P are cultivated. The left wall 120 encloses the left side of the area of ​​floor F where plants P are cultivated. The right wall 130 encloses the right side of the area of ​​floor F where plants P are cultivated. The rear wall 140 encloses the rear side of the area of ​​floor F where plants P are cultivated. The ceiling 150 encloses the upper side of the area of ​​floor F where plants P are cultivated.

[0053] The interior I1 is separated from the outside of the structure 100A and the passage 102 by the front wall 110, the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150. The space between the interior I1 and the exterior 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. This makes it difficult for people, equipment, and air to pass from the exterior of the structure 100A and the passage 102 to the interior I1. As a result, air supplied to the interior I1 through the opening 121 does not easily flow from the interior I1 to the exterior of the structure 100A. Air in space I3 also does not easily flow into the interior I1. People or equipment have difficulty approaching the interior I1. People or equipment cannot secure a workspace. A workspace is the space necessary for agricultural work.

[0054] Plant P is cultivated in the inner area I1. A portion or all of the bed F in the inner area I1 contains soil (not shown) into which plant P can be planted, or a nutrient solution (not shown) into which plant P can be immersed. In the inner area I1, plant P is either planted in the soil or immersed in the nutrient solution. Note that the cultivation of plant P in the inner area I1 does not necessarily mean that plant P is always present in the inner area I1. After plant P is harvested, there may be no plant P present in the inner area I1. Also, even if plant P is present in the inner area I1, it may not be visible to the naked eye because it has just been planted.

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

[0056] The front wall 110 (with nine slats SL), the left wall 120, the right wall 130, the rear wall 140, and the ceiling 150 include transparent or translucent vinyl, glass, or plastic film so that the light from the lighting in space I3 is transmitted to the interior I1. Because the front wall 110 (with nine slats SL), the left wall 120, the right wall 130, the rear wall 140, and the ceiling 150 are transparent or translucent, the plants P inside I1 are visible from the outside of the structure 100A. Note that case 114 does not necessarily have to include transparent or translucent vinyl, glass, or plastic film.

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

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

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

[0060] The left wall 120, the right 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, structure 100A is a variable structure. Note that at least one of the left wall 120, the right wall 130, the rear wall 140, and the ceiling 150 may be a component whose configuration can be changed. Various configurations of structure 100A will be described below.

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

[0062] Five of the nine slats SL are housed in case 114. The front of structure 100A connects the outside of structure 100A and passage 102 with the inside I1. The configuration of the front wall 110 has been changed from a state where the outside of structure 100A and passage 102 and inside I1 were blocked off to a state where the outside of structure 100A and passage 102 and inside I1 are connected. As a working space is secured, a person or equipment can perform agricultural work on the plants P through the front of structure 100A.

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

[0064] The nine slats SL are housed in case 114. The outside and passage 102 of structure 100A are connected to the inside I1 via the front of structure 100A. Because a working space is provided, a person or equipment performing agricultural work can perform agricultural work on plants P via the front of structure 100A.

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

[0066] (3) Operation The operation of equipment 1 when a person or device performs harvesting work will be described. Since the operation of structure 100A and structure 100B are similar, the operation of structure 100A will be described in detail. Figure 14 is a flowchart of the operation of equipment 1. Air heated by the air conditioner 11 is supplied to the inside I1 via the hose 111 and the opening 121. The configuration of structure 100A is shown in Figures 2, 3, 4, 5, 6, and 7.

[0067] The front wall 110 (with 9 slats SL) covers the front of the structure 100A. Therefore, the outside of the structure 100A and the passage 102 are isolated 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 is a suitable environment for cultivating plants P. The plants P are in a state suitable for harvesting (have finished growing). No workspace is provided.

[0068] A person or device moves from outside the greenhouse 10 into the greenhouse 10 via the entrance 101. The person or device moves to the front passage 102 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 other adjacent slats SL, the force in the Y direction is transmitted to the nine slats SL. As a result, the nine slats SL slide in the Y direction, guided by the first guide rail 112 and the second guide rail 113 (step S1).

[0069] As the slats SL slide in the Y direction, the upper slats SL out of the nine slats SL are housed in the case 114. Once five slats SL are housed in the case 114, the configuration of the structure 100A is changed to the configuration of the structure 100A in Figures 8, 9, and 10 (step S2). The configuration of the front wall 110 in Figure 3 is changed to the configuration of the front wall 110 in Figure 9. A person or device then applies 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 housed in the case 114. The configuration of structure 100A can be changed to the configuration of structure 100A in Figures 11, 12, and 13 (step S3). The configuration of the front wall 110 in Figure 9 can be changed to the configuration of the front wall 110 in Figure 12. The front side of structure 100A connects the outside of structure 100A and the passage 102 to the inside I1. With the working space secured, a person or device can perform harvesting work on the plant P. The person or device starts harvesting work on the plant P.

[0071] Once the harvesting operation is complete, a person or device applies a force in the negative Y direction to one or more of the nine slats SL housed in case 114. Because the slats SL are connected to each other, the force in the negative Y direction is transmitted to all nine slats SL. As a result, the nine slats SL slide in the negative Y direction, guided by the first guide rail 112 and the second guide rail 113 (step S4).

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

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

[0074] (4) Features (4-1) The variable structure is a variable structure installed inside another structure, and in which plants P are cultivated in inner I1 and inner I2, the variable structure comprises a first component whose configuration can be changed. By changing the configuration of the first component, the state in which the outside of the variable structure is separated from the inside I1 and inner I2 is changed to a state in which the outside is connected to the inside I1 and inner I2.

[0075] When cultivating plants inside a structure, air conditioning is provided to create an environment suitable for plant growth. The amount of energy required for air conditioning correlates with the volume of the structure's interior. Since plant cultivation requires agricultural work, the structure's interior must accommodate the space needed for this work. In non-variable structures whose configuration cannot be changed, the space required for agricultural work is maintained even when no work is being performed. Therefore, air conditioning is provided for the unnecessary space during times when no work is being done. This increases the amount of energy required for plant cultivation inside the structure, leading to increased costs associated with plant cultivation.

[0076] The variable structure is installed inside another structure, and plants P are cultivated in the inner I1 and inner I2. The variable structure can reduce the scope of air conditioning from the inside of the other structure to the inner I1 and inner I2. Therefore, the variable structure can achieve energy savings in the cultivation of plants P and reduce the cost of cultivating plants P.

[0077] The state in which the outside of the variable structure is separated from the inside I1 and inside I2 can be changed to a state in which the outside of the variable structure is connected to the inside I1 and inside I2. The state in which no workspace is secured can be changed to a state in which workspace is secured. As a result, the variable structure enables people or devices to work on plants P in the inside I1 and inside I2.

[0078] When a structure's configuration can be changed, it may be vulnerable to physical external forces. Therefore, strong winds, typhoons, and heavy snowfall can damage the structure. A variable structure is installed inside another structure. Therefore, the variable structure can protect plants P from physical external forces. Furthermore, the inner layers I1 and I2 provide double insulation from the outside. As a result, the variable structure can achieve energy savings in plant cultivation and reduce the cost of cultivating plants P.

[0079] (4-2) The variable structure has a first component facing an outer passage 102 used by a person or device when work is performed on the plant P by a person or device. By changing the configuration of the first component, the state can be changed from one in which the passage 102 is blocked from the inner I1 and inner I2 to one in which the passage 102 is connected to the inner I1 and inner I2.

[0080] The first component is more susceptible to forces from people or devices in the passageway 102. Therefore, the variable structure allows people or devices to easily change the configuration of the first component. Furthermore, the variable structure facilitates access to the plant P by people or devices from the passageway 102. Therefore, the variable structure facilitates work on the plant P by people or devices.

[0081] (4-3) The variable structure further comprises a first guide rail 112 provided substantially perpendicular to the internal floor F, and a second guide rail 113 provided opposite the first guide rail 112 and substantially perpendicular to the floor F. The configuration of the first component is changed by sliding guided by the first guide rail 112 and the second guide rail 113.

[0082] Since the first component is guided by the first guide rail 112 and the second guide rail 113, the force acting on the first component is less likely to be dispersed in an unspecified direction. The first component slides efficiently in a direction substantially perpendicular to the floor F. Therefore, the configuration of the first component of the variable structure can be easily changed by a person or device.

[0083] (4-4) The variable structure's first component is a front wall 110 erected on the interior floor F. The variable structure further comprises a ceiling 150 facing the floor F and in contact with the front wall 110, a rear wall 140 erected on the floor F, facing the front wall 110 and in contact with the ceiling 150, a left side wall 120 erected on the floor F and in contact with the front wall 110, the ceiling 150 and the rear wall 140, and a right side wall 130 erected on the floor F, facing the left side wall 120 and in contact with the front wall 110, the ceiling 150 and the rear wall 140. The area of ​​the floor F facing the ceiling 150 is enclosed by the front wall 110, the ceiling 150, the rear wall 140, the left side wall 120 and the right side wall 130, thereby forming interiors I1 and I2.

[0084] The variable structure can enclose the area of ​​the floor F and form inner areas I1 and I2 without requiring a bottom component facing the ceiling 150. The variable structure can be installed retrofitting even when plants P are already being cultivated on the floor F of another structure. Therefore, the variable structure can reduce the effort and cost of installation.

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

[0086] In other structures where a variable structure is installed, a light source may be provided. The variable structure transmits light from outside the variable structure to inside I1 and inside I2. Therefore, the variable structure can illuminate the plants P inside I1 and inside I2 with light from outside the variable structure.

[0087] (4-6) The variable structure is further provided with a supply unit for supplying conditioned air from the external air conditioner 11 to the internal I1 and internal I2.

[0088] Therefore, the variable structure can provide air conditioning for inner I1 and inner I2 through the supply unit, even without installing air conditioners in inner I1 and inner I2. Furthermore, because the variable structure does not require air conditioners in inner I1 and inner I2, inner I1 and inner I2 can be used more broadly for cultivating plants P.

[0089] (4-7) In a variable structure, the supply section is located approximately vertically below the approximate vertical center of the variable structure.

[0090] To create an environment suitable for plant cultivation, heating or humidification may be applied to the space where plants are located. Heated air is lighter than unheated air, so it rises from bottom to top. Similarly, humidified air is lighter than unheated air, so it also rises from bottom to top.

[0091] In a variable structure, the supply unit is located approximately vertically below the approximate vertical center of the variable structure. When heated or humidified air is supplied to the supply unit, the heated or humidified air moves approximately vertically downward to approximately vertically upward. The variable structure creates airflow in the inner parts I1 and I2, making it less likely for temperature and humidity unevenness to occur in the inner parts I1 and I2. Therefore, the variable structure makes the inner parts I1 and I2 an environment more suitable for the cultivation of plants P.

[0092] (4-8) The variable structure is further provided with an exhaust section for discharging the air inside I1 and inside I2 from inside I1 and inside I2 to the outside.

[0093] Because air is supplied to the inside of the structure, air inside the structure may be expelled through gaps in the structure. In this case, problems may arise where the air is not expelled smoothly, causing the internal air pressure to rise. Furthermore, problems may arise where gaps in the structure widen over time. In addition, the flow of air inside the structure becomes random depending on the location of the gaps, which may result in uneven temperature or humidity.

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

[0095] (4-9) The variable structure has a discharge section provided on a component of the variable structure that faces a component of the variable structure where a supply section is provided.

[0096] In some cases, an opening from the inside of a structure may be provided near an opening from the outside of the structure to the inside. In this case, air supplied from the outside to the inside of the structure can be immediately discharged from the inside to the outside of the structure. Therefore, temperature or humidity variations may occur in the vicinity of the opening from the outside to the inside of the structure and in the area far away.

[0097] The variable structure has an exhaust section provided on a component of the variable structure that faces a component of the variable structure where a supply section is provided. The variable structure forms airflow in the inner I1 and inner I2, making it less likely for temperature or humidity unevenness to occur in the inner I1 and inner I2. Therefore, the variable structure makes the inner I1 and inner I2 an environment more suitable for the cultivation of plants P.

[0098] (4-10) In a variable structure, if the supply section is located approximately vertically below the approximate vertical center of the variable structure, the discharge section is located approximately vertically above the approximate vertical center of the variable structure.

[0099] The variable structure creates airflow within the inner I1 and inner I2, making it less likely for temperature or humidity variations to occur within I1 and I2. Therefore, the variable structure creates an environment within I1 and I2 that is more suitable for the cultivation of plant P.

[0100] (4-11) The variable structure's discharge section 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 inner chambers I1 and I2 via the supply unit is discharged again to the intake port of the air conditioner 11. The air circulating between the air conditioner 11 and the inner chambers I1 and I2 is less likely to flow into the space I3. The air conditioner 11 can limit the air it conditioned to the air circulating between the air conditioner 11 and the inner chambers I1 and I2. Therefore, the variable structure can achieve energy savings in the cultivation of plants P and reduce the costs associated with cultivating plants P.

[0102] (5) Variant Regarding the modified version of the first embodiment, we will omit explanations of points that are the same as those of the first embodiment and focus on explaining the differences from the first embodiment.

[0103] (5-1) Variation 1A Case 114 may also be provided to serve as the ceiling 150. Figure 15 is a perspective view showing the detailed configuration of structure 100A according to Modification 1A. For example, case 114 in Modification 1A may be provided in the position of the ceiling 150 in the first embodiment. In Modification 1A, case 114 is an example of the ceiling 150. Case 114 faces the floor F and is in contact with the front wall 110, the left side wall 120, the right side wall 130, and the rear wall 140. Modification 114 is approximately parallel to the floor F and is approximately horizontal. Case 114 surrounds the upper part of the area of ​​floor F where plants P are cultivated.

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

[0105] (5-3) Modification 1C (5-3-1) Structure In the first embodiment, modified example 1A, and modified example 1B, structures 100A and 100B may be installed inside the mushroom cultivation facility 20 instead of inside the greenhouse 10. The mushroom cultivation facility 20 refers to a building or greenhouse in which mushrooms M are cultivated. Figure 17 is a schematic diagram showing the overall configuration of equipment 1 according to modified example 1C.

[0106] Racks R are provided in inner I1 and inner I2. Mycelial culture bottles B are placed on racks R. Mushrooms M are cultivated in mycelial culture bottles B. The mycelial culture bottles B and mushrooms M together are called set MS. Mushrooms M may be cultivated in mushroom bed bags instead of mycelial culture bottles B. Passageway 102 is a passageway in space I3 used by people or equipment when mushroom work (work generally performed on mushrooms M in the mushroom cultivation facility 20) is carried out.

[0107] Mushroom work refers to work performed on mushrooms M by people or equipment. Examples of mushroom work include inoculation, which involves planting mushroom spawn; cultivation, which is the work performed to grow mushrooms M; harvesting, which involves harvesting all or part of the mushrooms M; and other mushroom work. The workspace is the space necessary for mushroom work.

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

[0109] Rack R has multiple platforms 180 arranged approximately perpendicular to the floor F. For example, rack R has three platforms 180 arranged approximately perpendicular to the floor F. Mushrooms M are cultivated on each platform 180.

[0110] The depth of structure 100A (in other words, the depth of ceiling 150) is such that D6 and D7 are ensured. D6 is the shortest distance in the X direction from base 180 to front wall 110. D6 is preferably between 1 cm and 5 cm, but is not limited to this. D7 is the shortest distance in the negative X direction from base 180 to rear wall 140. D7 is preferably between 1 cm and 5 cm, but is not limited to this.

[0111] The height of structure 100A (in other words, the height of the front wall 110, the left wall 120, the right wall 130, and the rear wall 140) is such that D8 is secured. D8 is the shortest distance in the Y direction from the uppermost base 180 of mushroom M to the ceiling 150 when the mushroom M has finished growing. D8 is preferably between 1 and 10 centimeters, but is not limited to this.

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

[0113] (5-3-2) Characteristics (5-3-2-1) The variable structure is a variable structure installed inside another structure, and is a variable structure in which mushrooms M are cultivated in inner I1 and inner I2, and comprises a first component whose configuration can be changed. By changing the configuration of the first component, the state in which the outside of the variable structure is separated from the inside I1 and inner I2 is changed to a state in which the outside is connected to the inside I1 and inner I2.

[0114] When cultivating mushrooms inside a structure, air conditioning is provided to create an environment suitable for mushroom cultivation. Since mushroom cultivation requires manual work on the mushrooms, the structure must accommodate the necessary space for this work. In non-variable structures, even when no mushroom work is being performed, the necessary space remains. Therefore, air conditioning is provided for the unnecessary space during periods when no mushroom work is taking place. This increases the energy required for mushroom cultivation inside the structure, leading to increased costs.

[0115] The variable structure is installed inside another structure, and mushrooms M are cultivated in the inner I1 and inner I2. Therefore, the variable structure can achieve energy savings in mushroom cultivation and reduce the cost of cultivating mushrooms M.

[0116] The variable structure allows for human or equipment work on the mushroom M in the inner I1 and inner I2. Furthermore, the variable structure can protect the mushroom M from physical external forces. In addition, the variable structure, with its double insulation, enables energy savings in mushroom cultivation and reduces the cost of cultivating the mushroom M.

[0117] (5-3-2-2) The variable structure has a first component facing an outer passage 102 used by a person or device when work is performed on the mushroom M by a person or device. By changing the configuration of the first component, the state can be changed from one in which the passage 102 is blocked from the inner I1 and inner I2 to one in which the passage 102 is connected to the inner I1 and inner I2.

[0118] Therefore, the variable structure facilitates the work of people or equipment on the mushroom M.

[0119] (5-4) Modification 1D In the first embodiment, modified example 1A, and modified example 1B, structures 100A and 100B may be installed inside a plant factory 30 instead of inside a greenhouse 10. A plant factory 30 refers to a building in which plants P are cultivated. Figure 24 is a schematic diagram showing the overall configuration of equipment 1 according to modified example 1D.

[0120] Racks R are provided in inner sections I1 and I2. Plants P are cultivated on racks R. Plants P are planted in soil (not shown) on racks R or immersed in nutrient solution (not shown) on racks R. Lighting devices (not shown) that serve as light sources for plants P may be provided in structures 100A and 100B, or on racks R. The configuration of racks R is the same as in modified example 1C, so a description is omitted.

[0121] The depth and width of structure 100A in modified example 1D are the same as those of structure 100A in modified example 1C, so their explanation is omitted. The height of structure 100A (in other words, the height between the front wall 110, the left wall 120, the right 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 plant P to ceiling 150 when plant P has finished growing. D11 is preferably between 1 cm and 10 cm, but is not limited to this.

[0122] (5-5) Modification 1E (5-5-1) Structure In the first embodiment, modified example 1A, and modified example 1B, structures 100A and 100B may be installed inside the server room 40 instead of inside the greenhouse 10. The server room 40 is a room where servers are installed. The server room 40 may be installed inside other buildings (data centers, commercial buildings, industrial buildings, agricultural buildings, residential buildings, etc.). Figure 25 is a schematic diagram showing the overall configuration of equipment 1 according to modified example 1E.

[0123] In the inner areas I1 and I2, instead of cultivating plants P, servers SV are installed. The passage 102 is a passage in space I3 used by people or equipment when server work (work performed by server engineers on servers SV) is carried out.

[0124] Server work refers to work performed on a server (SV) by a person or equipment. Examples of server work include maintenance work to keep the server (SV) in working order, replacement work to replace all or part of the server (SV), testing work to test the server (SV), and other server work. The workspace is the space required for server work.

[0125] Furthermore, the space I3, which is outside structures 100A and 100B and inside the server room 40, may be furnished with desks and chairs and used as a workspace. Alternatively, desks and chairs may be placed in place of either structure 100A or structure 100B and used as a workspace. In addition to the server SV, or in place of the server SV, other machinery requiring air conditioning may be installed in the interior spaces I1 and I2.

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

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

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

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

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

[0132] (5-5-2) Features (5-5-2-1) The variable structure is a variable structure installed inside another structure, and comprises a first component whose configuration can be changed, on which a server SV is installed in the inner I1 and inner I2. By changing the configuration of the first component, the state in which the outside of the variable structure is isolated from the inner I1 and inner I2 can be changed to a state in which the outside is connected to the inner I1 and inner I2.

[0133] When servers are installed inside a structure, air conditioning is provided within the structure to create an environment suitable for server operation. Since server operation requires server maintenance, the structure must accommodate the necessary space for server maintenance. In non-variable structures, even when server maintenance is not being performed, the necessary space remains. Therefore, air conditioning is provided for this unnecessary space during periods when server maintenance is not in progress. This increases the energy required for server operation within the structure, leading to increased operating costs.

[0134] The variable structure is installed inside another structure, with the server SV installed in inner I1 and inner I2. Therefore, the variable structure can achieve energy savings in the operation of the server SV and reduce the costs associated with operating the server SV.

[0135] The variable structure allows for human or equipment access to the server SV in the inner I1 and inner I2. Furthermore, the variable structure protects the server SV from physical external forces. Additionally, the dual insulation of the variable structure enables energy savings in server SV operation and reduces operating costs.

[0136] (5-5-2-2) The variable structure has a first component facing an outer passage 102, which is used by people or devices when work is performed on the server SV by people or devices. By changing the configuration of the first component, the state can be changed from one in which the passage 102 is blocked from the inner I1 and inner I2 to one in which the passage 102 is connected to the inner I1 and inner I2.

[0137] Therefore, the variable structure facilitates the work of people or equipment on the server SV.

[0138] (5-5-2-3) In a variable structure, the supply section is located approximately vertically above the approximate vertical center of the variable structure.

[0139] To create an environment suitable for server operation, the space where the servers are installed may be cooled or dehumidified. Cooled air is heavier than uncooled air, so it moves from top to bottom. Similarly, dehumidified air is heavier than unhumidified air, so it also moves from top to bottom.

[0140] In a variable structure, the supply unit is located approximately vertically above the approximate vertical center of the variable structure. When cooled or dehumidified air is supplied to the supply unit, the cooled or dehumidified air moves approximately vertically upward to approximately vertically downward. The variable structure creates airflow in the inner I1 and inner I2, making it less likely for temperature and humidity unevenness to occur in the inner I1 and inner I2. Therefore, the variable structure makes the inner I1 and inner I2 an environment more suitable for the operation of the server SV.

[0141] (5-5-2-4) In a variable structure, if the supply section is located approximately vertically above the approximate vertical center of the variable structure, the discharge section is located approximately vertically below the approximate vertical center of the variable structure.

[0142] The variable structure creates airflow within the inner I1 and inner I2, making it less likely for temperature or humidity unevenness to occur within I1 and inner I2. Therefore, the variable structure makes the environment within I1 and inner I2 more suitable for the operation of the server SV.

[0143] (5-6) Modification 1F (5-6-1) Structure In the first embodiment, modification 1A, and modification 1B, structures 100A and 100B may be installed inside a warehouse 50 instead of inside a greenhouse 10. Examples of warehouses 50 include, but are not limited to, a freezer warehouse and a refrigerated warehouse. Figure 32 is a schematic diagram showing the overall configuration of equipment 1 according to modification 1F. Inside I1 and inside I2, goods G are stored instead of plants P being cultivated.

[0144] Specifically, racks R are provided in inner I1 and inner I2, and goods G are stored in racks R. Goods G include goods packaged in cardboard boxes, etc. Racks R are the same as in Modification 1C, so their explanation is omitted. Passageway 102 is a passageway in space I3 used by people or equipment when warehouse work is performed.

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

[0146] The depth and width of structure 100A are the same as in modified example 1C, so their description is omitted. The height of structure 100A (in other words, the height between the front wall 110, the left wall 120, the right 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 goods G stored on the top shelf 180 of rack R to the ceiling 150. D17 is preferably between 5 and 10 centimeters, but is not limited to this.

[0147] Openings 121 and 131 are the same as in Modification 1E, so their explanation will be omitted.

[0148] (5-6-2) Characteristics (5-6-2-1) The variable structure is a variable structure installed inside another structure, and comprises a first component whose configuration can be changed, in which the product G is stored in the inner I1 and inner I2. By changing the configuration of the first component, the state in which the outside of the variable structure is separated from the inner I1 and inner I2 is changed to a state in which the outside is connected to the inner I1 and inner I2.

[0149] When storing goods inside a structure, air conditioning is provided to create an environment suitable for goods storage. Since goods storage requires warehouse operations, the interior of the structure must accommodate the space necessary for these operations. In non-variable structures, the space required for warehouse operations is maintained even when no operations are taking place. Therefore, air conditioning is provided for the unnecessary space during periods when no warehouse operations are being performed. This increases the energy required for goods storage inside the structure, leading to increased storage costs.

[0150] The variable structure is installed inside another structure, and product G is stored in inner I1 and inner I2. Therefore, the variable structure can achieve energy savings in the storage of product G and reduce the costs associated with storing product G.

[0151] The variable structure allows for human or equipment to work on the product G in the interior I1 and interior I2. Furthermore, the variable structure can protect the product G from physical external forces. In addition, the variable structure, with its double insulation, enables energy savings in the storage of product G and reduces storage costs.

[0152] (5-6-2-2) The variable structure has a first component facing an outer passage 102 used by people or devices when work is performed on product G by people or devices. By changing the configuration of the first component, the state can be changed from one in which the passage 102 is blocked from the inner I1 and inner I2 to one in which the passage 102 is connected to the inner I1 and inner I2.

[0153] Therefore, the variable structure facilitates the work of people or equipment on product G.

[0154] (5-7) Variation 1G (5-7-1) Composition In the first embodiment, modification 1A, and modification 1B, structures 100A and 100B may be installed inside the livestock shed 60 instead of inside the greenhouse 10. Figure 33 is a schematic diagram showing the overall configuration of equipment 1 according to modification 1G. In the inner I1 and inner I2, livestock L are raised instead of plants P. In Figure 33, livestock L are cattle, but are not limited to cattle. The passage 102 is a passage in space I3 used by people or equipment when livestock work is performed.

[0155] Livestock farming operations are tasks performed on livestock L by people or equipment. Examples of livestock farming operations include feeding livestock L, cleaning operations to remove manure and urine from livestock L, health operations such as treatment, prevention, and breeding of livestock L, harvesting operations such as harvesting eggs, wool, meat, and milk from livestock L, and other livestock farming operations. The work space is the space necessary for livestock farming operations.

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

[0157] (5-7-2) Characteristics (5-7-2-1) The variable structure is a variable structure installed inside another structure, and livestock L are kept in the inner I1 and inner I2 of the variable structure, and comprises a first component whose configuration can be changed. By changing the configuration of the first component, the state in which the outside of the variable structure is separated from the inside I1 and inner I2 is changed to a state in which the outside is connected to the inside I1 and inner I2.

[0158] When livestock are raised inside a structure, air conditioning is provided to the interior of the structure to create an environment suitable for raising livestock. Since livestock raising requires livestock farming work, the interior of the structure is designed to accommodate the space needed for this work. In the case of non-variable structures whose configuration cannot be changed, the space necessary for livestock farming is maintained even when no livestock farming work is being performed. Therefore, air conditioning is provided for the unnecessary space during times when livestock farming is not being carried out. This increases the amount of energy required to raise livestock inside the structure, leading to increased costs associated with livestock farming.

[0159] The variable structure is installed inside another structure, and livestock L are raised in the inner I1 and inner I2. Therefore, the variable structure can achieve energy savings in raising livestock L and reduce the costs associated with raising livestock L.

[0160] The variable structure allows for human or equipment work on livestock L in the inner I1 and inner I2. Furthermore, the variable structure can protect livestock L from physical external forces. In addition, the variable structure, with its double insulation, enables energy savings in livestock rearing and reduces the costs associated with raising livestock L.

[0161] (5-7-2-2) The variable structure has a first component facing an outer passage 102 used by a person or device when work is performed on the livestock L by a person or device. By changing the configuration of the first component, the state can be changed from one in which the passage 102 is blocked from the inner I1 and inner I2 to one in which the passage 102 is connected to the inner I1 and inner I2.

[0162] Therefore, the variable structure facilitates the work of people or equipment on livestock L.

[0163] (5-8) Modification 1H (5-8-1) Composition In the first embodiment, modified example 1A, and modified example 1B, structures 100A and 100B may be installed inside the land-based aquaculture farm 70 instead of inside the greenhouse 10. Figure 34 is a schematic diagram showing the overall configuration of equipment 1 according to modified example 1H. In the inner areas I1 and I2, aquatic organisms Q are farmed instead of plants P. Specifically, tanks A are provided in the inner areas I1 and I2, and aquatic organisms Q are farmed in the water W stored in the tanks A. The aquatic organisms Q in Figure 34 are fish, but are not limited to fish. The passageway 102 is a passageway in space I3 used by people or equipment when aquaculture work is carried out.

[0164] Aquaculture operations are human or equipment-based operations performed on aquatic organisms Q. Examples of aquaculture operations include feeding aquatic organisms Q, cleaning operations such as removing waste and cleaning tanks A, water operations such as supplying water W, changing water W, and testing water quality, health operations such as treating, preventing, and breeding aquatic organisms Q, harvesting operations such as harvesting eggs and flesh of aquatic organisms Q, and other aquaculture operations. The workspace is the space necessary for aquaculture operations.

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

[0166] (5-8-2) Features (5-8-2-1) The variable structure is a variable structure installed inside another structure, and in which aquatic organisms Q are cultivated in inner I1 and inner I2, the variable structure comprises a first component whose configuration can be changed. By changing the configuration of the first component, the state in which the outside of the variable structure is separated from inner I1 and inner I2 is changed to a state in which the outside is connected to inner I1 and inner I2.

[0167] When cultivating aquatic organisms inside a structure, air conditioning is provided within the structure to create an environment suitable for aquatic organism cultivation. Since cultivating aquatic organisms requires cultivation work, the structure must accommodate the necessary space for this work. In the case of non-variable structures, the space required for cultivation is maintained even when no cultivation work is being performed. Therefore, air conditioning is provided for the unnecessary space during periods when no cultivation work is taking place. This increases the energy required for cultivating aquatic organisms inside the structure, leading to increased costs for aquatic organism cultivation.

[0168] The variable structure is installed inside another structure, and aquatic organisms Q are cultivated in the inner I1 and inner I2. Therefore, the variable structure can achieve energy savings in the cultivation of aquatic organisms Q and reduce the costs associated with cultivating them.

[0169] The variable structure allows for human or equipment work on aquatic organisms Q in the inner I1 and inner I2. Furthermore, the variable structure can protect the aquatic organisms Q from physical external forces. In addition, the variable structure, with its double insulation, enables energy savings in the cultivation of aquatic organisms Q and reduces the costs associated with their cultivation.

[0170] (5-8-2-2) The variable structure has a first component facing an outer passage 102, which is used by a person or device when work is performed on an aquatic organism Q by a person or device. By changing the configuration of the first component, the state can be changed from one in which the passage 102 is blocked from the inner I1 and inner I2 to one in which the passage 102 is connected to the inner I1 and inner I2.

[0171] Therefore, the variable structure facilitates the work of people or devices on aquatic organisms Q.

[0172] (5-9) Modification 1I In the first embodiment and modifications 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, the front wall 110 may be modified by control of a control device (not shown). In other words, the slat SL may slide along 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 equipment 2 according to the second embodiment will be described below. Hereinafter, similarities between the first and second embodiments will be omitted, and the differences between the first and second embodiments will be the focus of the description. Figure 35 is a schematic diagram showing the overall configuration of equipment 2 according to the second embodiment. Equipment 2 mainly comprises a greenhouse 10 and an air conditioner 11.

[0174] (1-1) Greenhouse The interior of the greenhouse 10 mainly consists of structure 200A and structure 200B. Structures 200A and 200B divide the interior of the greenhouse 10 into three areas: the area inside structure 200A I4, the area inside structure 200B I5, and the area outside structures 200A and 200B, which is the interior of the greenhouse 10. Details of structures 200A and 200B will be described later.

[0175] In addition, facility 2 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 10.

[0176] (1-2) Air conditioner The air conditioner 11 is connected to the interior I4 by hoses 115 and 116. The air conditioner 11 is also connected to the interior I5 by two hoses (not shown) different from hoses 115 and 116. The air conditioned by the air conditioner 11 is supplied to the interior I4 and interior I5 via hoses 115 and 116, etc.

[0177] (2) Detailed configuration The detailed configurations of structures 200A and 200B will now be described. Structure 200A is a variable structure whose configuration can be changed by the operation of structure 200A. Structure 200B is a variable structure whose configuration can be changed by the operation of structure 200B. The structure of structure 200A and the structure of structure 200B are substantially symmetric with respect to the planes extending in the Y and Z directions. The functions of structure 200A and structure 200B are the same. The structure and function of structure 200A will be described below.

[0178] Figure 36 is a perspective view showing the detailed configuration of structure 200A. Figure 37 is a front view showing the detailed configuration of structure 200A. Figure 38 is a rear view showing the detailed configuration of structure 200A. Figure 39 is a left side view showing the detailed configuration of structure 200A. Figure 40 is a right side view showing the detailed configuration of structure 200A. Figure 41 is a top view showing the detailed configuration of structure 200A. In Figures 36, 37, 38, 39, 40, and 41, plant P is in a state where it has finished growing.

[0179] Structure 200A mainly consists of a front wall 210, a third guide rail 211, a fourth guide rail 212, a case 213, a left side wall 220, a right side wall 230, a rear wall 240, and a ceiling 250.

[0180] The third guide rail 211 is installed approximately parallel to the floor F. The fourth guide rail 212 is installed opposite the third guide rail 211 and approximately parallel to the floor F.

[0181] The front wall 210 is mainly composed of multiple slats SL. For example, the front wall 210 is mainly composed of 14 slats SL. The slats SL are connected to other adjacent slats SL. The slats SL are substantially perpendicular to the floor F. The slats SL can be slid in the Z direction or the negative Z direction (the direction in which the third guide rails 211 and the fourth guide rails 212 extend), guided by the third guide rail 211 and the fourth guide rail 212. The appearance of the front wall 210 is changed by the sliding of the slats SL guided by the third guide rail 211 and the fourth guide rail 212.

[0182] The front wall 210 is an example of the first component and is erected approximately perpendicular to the floor F. The front wall 210 faces the passageway 102.

[0183] Case 213 is provided on the right side of the front wall 210 and behind the third guide rail 211 and the fourth guide rail 212. Case 213 accommodates the slats SL that slide in the Z direction. Case 213 is provided so as to accommodate all of the slats SL that make up the front wall 210. Case 213 may also be provided on the left side of the front wall 210.

[0184] The left wall 220 faces the right wall 230 and is erected approximately perpendicular to the floor F. The left wall 220 is in contact with the front wall 210, the rear wall 240, and the ceiling 250. The left wall 220 is provided with a first opening 221 that communicates with the hose 115 and a second opening 222 that communicates with the hose 116. The first opening 221 and the second opening 222 are included in the supply section.

[0185] The first opening 221 is located approximately vertically below the approximate vertical center of the left wall 220. In other words, the first opening 221 is located approximately vertically below the approximate vertical center of the structure 200A. The first opening 221 is located behind the approximate 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 interior I4. The first opening 221 is also an opening for supplying humidified air from the air conditioner 11 to the interior I4.

[0186] The second opening 222 is located approximately vertically above the approximate vertical center of the left wall 220. In other words, the second opening 222 is located approximately vertically above the approximate vertical center of the structure 200A. The second opening 222 is located behind 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 interior I4. The first opening 221 is an opening for supplying dehumidified air from the air conditioner 11 to the interior I4.

[0187] The first opening 221 and the second opening 222 may be provided in the front wall 210, the right wall 230, the rear wall 240, or the ceiling 250 instead of the left wall 220. The first opening 221 and the second opening 222 may also be provided in at least one of the front wall 210, the right wall 230, the rear wall 240, or the ceiling 250, in addition to the left wall 220. The first opening 221 and the second opening 222 may be provided in front of the approximate center in the X direction of the structure 200A. The first opening 221 and the second opening 222 may be provided in different walls.

[0188] The right-side wall 230 faces the left-side wall 220 and is erected approximately 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.

[0189] Opening 231 is an example of a discharge section. Opening 231 is provided in the right-side wall 230, opposite the left-side wall 220 where the first opening 221 and the second opening 222 are provided. Opening 231 is provided approximately in the center of the right-side wall 230 in the approximately vertical direction. In other words, opening 231 is provided approximately in the center of the structure 200A in the approximately vertical direction. Opening 231 is provided behind the center of the structure 200A in the approximately X direction.

[0190] The air inside I4 is discharged from inside I4 to the outside of the structure 200A through the opening 231. 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 inside I4 flows to the intake port of the air conditioner 11 via the opening 231 and the hose.

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

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

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

[0194] The area of ​​floor F opposite the ceiling 250 is enclosed by the front wall 210, the left wall 220, the right wall 230, the rear wall 240, and the ceiling 250, thereby forming the interior I4. Specifically, the front wall 210 encloses the front side of the area of ​​floor F where plants P are cultivated. The left wall 220 encloses the left side of the area of ​​floor F where plants P are cultivated. The right wall 230 encloses the right side of the area of ​​floor F where plants P are cultivated. The rear wall 240 encloses the rear side of the area of ​​floor F where plants P are cultivated. The ceiling 250 encloses the upper side of the area of ​​floor F where plants P are cultivated.

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

[0196] Plant P is cultivated in the inner area I4. Part or all of the bed F in the inner area I4 is filled with soil (not shown) into which plant P can be planted, or with a nutrient solution (not shown) into which plant P can be immersed. In the inner area I4, plant P is either planted in the soil or immersed in the nutrient solution. Note that the cultivation of plant P in the inner area I4 does not mean that plant P is always present in the inner area I4. After plant P is harvested, there may be no plant P in the inner area I4. Also, even if plant P is present in the inner area I4, it may not be visible to the naked eye because it has just been planted.

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

[0198] The front wall 210 (14 slats SL), the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250 include transparent or translucent vinyl, glass, or plastic film so that the light for illuminating the space I6 is transmitted to the inside I4. Since the front wall 210 (14 slats SL), the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250 are transparent or translucent, the plants P inside I4 can be seen through from the outside of the structure 200A. Note that the case 213 may not include transparent or translucent vinyl, glass, or plastic film.

[0199] The depth of the structure 200A (in other words, the depth of the ceiling 250) is a value at which D18 and D19 are ensured. 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 from 1 centimeter to 10 centimeters, but is not limited thereto. D19 is the shortest distance in the minus X direction from the plant P to the rear wall 240 when the plant P has finished growing. D19 is preferably from 1 centimeter to 10 centimeters, but is not limited thereto.

[0200] The height of the structure 200A (in other words, the height of the front wall 210, the left side wall 220, the right side wall 230, and the rear wall 240) is a value at which D20 is ensured. 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 from 1 centimeter to 10 centimeters, but is not limited thereto.

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

[0202] The left wall 220, the right 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, structure 200A is a variable structure. Note that at least one of the left wall 220, the right wall 230, the rear wall 240, and the ceiling 250 may be a component whose configuration can be changed. Various configurations of structure 200A will be described below.

[0203] Figure 42 is a perspective view showing the detailed configuration of structure 200A. Figure 43 is a front view showing the detailed configuration of structure 200A. Figure 44 is a rear view showing the detailed configuration of structure 200A. The configuration of structure 200A in Figures 42, 43, and 44 is a configuration in which the slat SL is slid in the Z direction from the configuration of structure 200A in Figures 36, 37, 38, 39, 40, and 41. In this case, the left side view, right side view, and top view showing the detailed configuration of structure 200A are the same as in Figures 39, 40, and 41, and are therefore omitted.

[0204] Of the 14 slats SL, 7 slats SL are housed in case 213. The outside of structure 200A and passage 102 are connected to the inside I4 via the front of structure 200A. The configuration of the front wall 210 has been changed from a state where the outside of structure 200A and passage 102 and inside I4 were blocked off to a state where the outside of structure 200A and passage 102 and inside I4 are connected. Since a working space is secured, a person or equipment performing agricultural work can perform agricultural work on plants P via the front of structure 200A.

[0205] Figure 45 is a perspective view showing the detailed configuration of structure 200A. Figure 46 is a front view showing the detailed configuration of structure 200A. Figure 47 is a rear view showing the detailed configuration of structure 200A. The configuration of structure 200A in Figures 45, 46, and 47 is a configuration in which the slat SL is slid in the Z direction from the configuration of structure 200A in Figures 42, 43, and 44. In this case, the left side view, right side view, and top view showing the detailed configuration of structure 200A are the same as in Figures 39, 40, and 41, and are therefore omitted.

[0206] The 14 slats SL are housed in case 213. The outside and passage 102 and the inside I4 of structure 200A are connected via the front of structure 200A. Because a working space is provided, a person or equipment performing agricultural work can perform agricultural work on plants P via the front of structure 200A.

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

[0208] (3) Operation The operation of equipment 2 when a person or device performs harvesting work will be described. Since the operation of structure 200A and structure 200B are similar, the operation of structure 200A will be described in detail. Figure 48 is a flowchart of the operation of 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 configuration of structure 200A is shown in Figures 36, 37, 38, 39, 40, and 41.

[0209] Because 14 slats SL cover the front of structure 200A, the outside of structure 200A and passage 102 are isolated from the inside I4. The heated air supplied to inside I4 does not easily flow to the outside of structure 200A. The temperature inside I4 is maintained higher than the temperature of space I6. Therefore, inside I4 is a suitable environment for cultivating plant P. Plant P is in a state suitable for harvesting. No workspace is provided.

[0210] A person or device moves from outside the greenhouse 10 into the greenhouse 10 via the entrance 101. The person or device moves to the front passage 102 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 other adjacent slats SL, the force in the Z direction is transmitted to all 14 slats SL. As a result, the 14 slats SL slide in the Z direction, guided by the third guide rail 211 and the fourth guide rail 212 (step S11).

[0211] As the slats SL slide in the Z direction, the rightmost of the 14 slats SL are housed in the case 213. Once seven slats SL are housed in the case 213, the configuration of the structure 200A is changed to the configuration of the structure 200A in Figures 42, 43, and 44 (step S12). The configuration of the front wall 210 in Figure 37 is changed to the configuration of the front wall 210 in Figure 43. A person or device then applies a force in the Z direction to one or more slats SL.

[0212] As the slats SL slide in the Z direction, the 14 slats SL are housed in the case 213. The configuration of structure 200A can be changed to the configuration of structure 200A in Figures 45, 46, and 47 (step S13). The configuration of the front wall 110 in Figure 43 can be changed to the configuration of the front wall 210 in Figure 46. The front side of structure 200A connects the outside of structure 200A and the passage 102 to the inside I4. With the working space secured, a person or device can perform harvesting work on the plant P. The person or device starts harvesting work on the plant P.

[0213] Once the harvesting operation is complete, a person or device applies a force in the negative Z direction to one or more slats SL housed in case 213. Because the slats SL are connected to other adjacent slats SL, the force in the negative Z direction is transmitted to 14 slats SL. As a result, the 14 slats SL slide in the negative Z direction, guided by the third guide rail 211 and the fourth guide rail 212 (step S14).

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

[0215] When the 14 slats SL are pulled out to the left from case 213, the configuration of structure 200A is changed to the configuration of structure 200A in Figures 36, 37, 38, 39, 40, and 41 (step S16). The configuration of the front wall 210 in Figure 43 is changed to the configuration of the front wall 210 in Figure 37. The front side of structure 200A is covered by the 14 slats SL. As a result, the outside of structure 200A and the passage 102 and the inside I4 are separated.

[0216] A person or device moves outside the greenhouse 10 via the passage 102 and the entrance / exit 101. The person or device operates the air conditioner 11 so that it stops heating and starts dehumidifying. The supply of heated air from 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 hose 116 and the second opening 222. The humidity inside I4 decreases and becomes lower than the humidity outside the structure 200A. As a result, the inside I4 becomes a suitable environment for sowing.

[0217] (4) Features (4-1) The variable structure further comprises a third guide rail 211 provided substantially parallel to the internal floor F, and a fourth guide rail 212 provided opposite the third guide rail 211 and substantially parallel to the floor F. The configuration of the first component is changed by sliding guided by the third guide rail 211 and the fourth guide rail 212.

[0218] Since the first component is guided by the third guide rail 211 and the fourth guide rail 212, the force acting on the first component is less likely to be dispersed in an unspecified direction. The first component slides efficiently in a direction substantially parallel to the floor F. Therefore, the configuration of the first component of the variable structure can be easily changed by a person or device.

[0219] (4-2) The variable structure includes a supply section comprising a first opening 221 located approximately vertically below the approximate vertical center of the variable structure and a second opening 222 located approximately vertically above the approximate vertical center of the variable structure, wherein the first opening 221 is for supplying heated air from the air conditioner 11 to the inner I4 and inner I5, and the second opening 222 is for supplying cooled air from the air conditioner 11 to the inner I4 and inner I5.

[0220] To create an environment suitable for plant cultivation, heating and cooling may be performed in the space where the plants are cultivated. 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 either heating or cooling is performed.

[0221] The variable structure is provided with a first opening 221 for supplying heated air to the inner sides I4 and I5, and a second opening 222 for supplying cooled air to the inner sides I4 and I5. Therefore, the variable structure makes it difficult for temperature unevenness to occur in the inner sides I4 and I5 in the case of heating and cooling. Therefore, the variable structure makes the inner sides I4 and I5 an environment more suitable for cultivating the plant P.

[0222] (4-3) The variable structure includes a first opening 221 provided substantially vertically below the center of the variable structure in the substantially vertical direction, and a second opening 222 provided substantially vertically above the center of the variable structure in the substantially vertical direction. The first opening 221 is an opening for supplying the humidified air from the air conditioner 11 to the inner sides I4 and I5, and the second opening 222 is an opening for supplying the dehumidified air from the air conditioner 11 to the inner sides I4 and I5.

[0223] To create an environment suitable for plant cultivation, humidification and dehumidification may be performed in the space where the plants are cultivated. Humidified air is lighter than unhumidified air. However, dehumidified air is heavier than undehumidified air. Therefore, if humidification and dehumidification are performed through the same opening, humidity unevenness may occur when at least either humidification or dehumidification is performed.

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

[0225] (5) Variant Regarding the modified version of the second embodiment, we will omit explanations of points that are the same as those of the second embodiment and focus on explaining the differences from the second embodiment.

Specifically, racks R are provided inside I4 and I5, and goods G are stored in racks R. Since racks R are the same as in modified example 1C, their explanation is omitted.

[0237] The depth and width of structure 200A are the same as in modified example 2A, so their description is omitted.

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

[0244] (1-1) Greenhouse The interior of the greenhouse 10 mainly consists of structure 300A and structure 300B. Structures 300A and 300B divide the interior of the greenhouse 10 into three areas: the area inside structure 300A I7, the area inside structure 300B I8, and the area outside structures 300A and 300B, which is also the interior of the greenhouse 10. Details of structures 300A and 300B will be described later.

[0245] In addition, facility 3 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 10.

[0246] (1-2) Air conditioner The air conditioner 11 is connected to the inner chamber I7 by a hose (not shown) and to the inner chamber I8 by another hose (not shown). The air conditioned by the air conditioner 11 is supplied to the inner chambers I7 and I8 via the hoses and the like.

[0247] (2) Detailed configuration The detailed configurations of structures 300A and 300B will now be described. Structure 300A is a variable structure whose configuration can be changed by the operation of structure 300A. Structure 300B is a variable structure whose configuration can be changed by the operation of structure 300B. The structure of structure 300A and the structure of structure 300B are substantially symmetric with respect to the planes extending in the Y and Z directions. The functions of structure 300A and structure 300B are the same. The structure and function of structure 300A will be described below.

[0248] Figure 56 is a perspective view showing the detailed configuration of structure 300A. Figure 57 is a front view showing the detailed configuration of structure 300A. Figure 58 is a rear view showing the detailed configuration of structure 300A. Figure 59 is a left side view showing the detailed configuration of structure 300A. Figure 60 is a right side view showing the detailed configuration of structure 300A. Figure 61 is a top view showing the detailed configuration of structure 300A. In Figures 56, 57, 58, 59, 60, and 61, plant P is in a state where it has finished growing.

[0249] Structure 300A mainly consists of 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 installed 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 is positioned opposite the third guide rail 311 and is installed 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 substantially perpendicular to the floor F. The two slats SL are guided by a third guide rail 311 and a 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 appearance of the front wall 310 is changed by the sliding of the two slats SL guided by the third guide rail 311 and the fourth guide rail 312.

[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 slide 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 the first component and is erected approximately perpendicular to the floor F. The front wall 310 faces the passageway 102.

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

[0256] The right wall 330 faces the left wall 320 and is erected approximately perpendicular to the floor F. The right 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 is erected approximately perpendicular to the floor F. The rear wall 340 is in contact with the left wall 320, the right 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 interior I7 through the opening 341. The opening 341 is located approximately vertically below the approximate vertical center of the rear wall 340. In other words, the opening 341 is located approximately vertically below the approximate vertical center of the structure 300A. The opening 341 is located to the left of the approximate Z-center of the structure 300A.

[0259] The opening 341 may be provided in 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 also be provided in 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 approximate vertical center of the rear wall 340. The opening 341 may also be provided to the right of the approximate Z-center of the structure 300A.

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

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

[0262] The opening 342 may be provided in 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 342 may also be provided in at least one 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 342 may be provided approximately vertically below the center of the rear wall 340 in the approximately vertical direction. The opening 342 may be provided to the left of the center of the structure 300A in the approximately Z direction. The opening 342 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the intake port of the air conditioner 11.

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

[0264] The area of ​​floor F facing ceiling 350 is enclosed by the front wall 310, left wall 320, right wall 330, rear wall 340, and ceiling 350, thereby forming the interior I7. Specifically, the front wall 310 encloses the front side of the area of ​​floor F where plants P are cultivated. The left wall 320 encloses the left side of the area of ​​floor F where plants P are cultivated. The right wall 330 encloses the right side of the area of ​​floor F where plants P are cultivated. The rear wall 340 encloses the rear side of the area of ​​floor F where plants P are cultivated. The ceiling 350 encloses the upper side of the area of ​​floor F where plants P are cultivated.

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

[0266] Plant P is cultivated in the inner I7. Some of the bed F in the inner I7 is filled with soil (not shown) in which plant P can be planted, or with a nutrient solution (not shown) in which plant P can be immersed. In the inner I7, plant P is either planted in soil or immersed in nutrient solution. Note that the cultivation of plant P in the inner I7 does not mean that plant P is always present in the inner I7. After plant P is harvested, there may be no plant P in the inner I7. Also, even if plant P is present in the inner I7, it may not be visible to the naked eye because it has just been planted.

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

[0268] The front wall 310 (with two slats SL), the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 include transparent or translucent vinyl, glass, or plastic film so that the light from the lighting in space I9 is ​​transmitted to the interior I7. Because the front wall 310 (with two slats SL), the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 are transparent or translucent, the plants P in the interior I7 are visible from the outside of the structure 300A.

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

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

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

[0272] The left wall 320, the right 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, structure 300A is a variable structure. Note that at least one of the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 may be a component whose configuration can be changed. Various configurations of structure 300A will be described below.

[0273] Figure 62 is a perspective view showing the detailed configuration of structure 300A. Figure 63 is a front view showing the detailed configuration of structure 300A. Figure 64 is a rear view showing the detailed configuration of structure 300A. The configuration of structure 300A in Figures 62, 63, and 64 is the same as the configuration of structure 300A in Figures 56, 57, 58, 59, 60, and 61, but with the left slat SL slid in the Z direction. In this case, the left side view, right side view, and top view showing the detailed configuration of structure 300A are the same as in Figures 59, 60, and 61, and are therefore omitted.

[0274] The left slat SL has slid in the Z direction, so it is roughly aligned with the right slat SL in the X direction. The inner I7 is connected to the outside of the structure 300A and the passage 102 via the left front side of the structure 300A. The configuration of the front wall 310 has been changed from a state where the outside of the structure 300A and the passage 102 were blocked from the inner I7 to a state where the outside of the structure 300A and the passage 102 are connected to the inner I7. As a working space has been secured, a person or equipment performing agricultural work can perform agricultural work on the plants P via the front side of the structure 300A.

[0275] Figure 65 is a perspective view showing the detailed configuration of structure 300A. Figure 66 is a front view showing the detailed configuration of structure 300A. Figure 67 is a rear view showing the detailed configuration of structure 300A. The configuration of structure 300A in Figures 65, 66, and 67 is the same as that of structure 300A in Figures 56, 57, 58, 59, 60, and 61, but with the right slat SL slid in the minus Z direction. In this case, the left side view, right side view, and plan view showing the detailed configuration of structure 300A are the same as in Figures 59, 60, and 61, and are therefore omitted.

[0276] The right slat SL has been slid in the negative Z direction, so it is roughly aligned with the left slat SL in the X direction. The inner I7 is connected to the outside of the structure 300A and the passage 102 via the right front side of the structure 300A. The configuration of the front wall 310 has been changed from a state where the outside of the structure 300A and the passage 102 were blocked from the inner I7 to a state where the outside of the structure 300A and the passage 102 are connected to the inner I7. As a working space has been secured, a person or equipment performing agricultural work can perform agricultural work on the plants P via the front side of the structure 300A.

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

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

[0279] (3) Operation The operation of equipment 3 when a person or device performs harvesting work will be described. Since the operation of structure 300A and structure 300B are similar, the operation of structure 300A will be described in detail. Figure 68 is a flowchart of the operation of equipment 3. Air heated by the air conditioner 11 is supplied to the inside I7 via the hose and opening 341. The configuration of structure 300A is shown in Figures 56, 57, 58, 59, 60, and 61.

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

[0281] A person or device moves from outside the greenhouse 10 into the greenhouse 10 via the entrance / exit 101. The person or device moves to the front passage 102 of the structure 300A. The person or device applies a force in the Z direction to the left of the two slats SL. Since 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 slides in the Z direction, guided by the third guide rail 311 and the fourth guide rail 312 (step S21).

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

[0283] Once the harvesting operation for the plant P on the left is completed, a person or device applies a force in the negative Z direction to the left slat SL. Since 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 slid in the negative Z direction, guided by the third guide rail 311 and the fourth guide rail 312 (step S23).

[0284] As the left slat SL is slid in the negative Z direction, the configuration of structure 300A is changed to the configuration of structure 300A in Figures 56, 57, 58, 59, 60, and 61 (step S24). The configuration of the front wall 310 in Figure 63 is changed to the configuration of the front wall 310 in Figure 57. As the left front side of structure 300A is covered by the left slat SL, the outside of structure 300A and the passage 102 are separated 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. Since 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 slid in the negative Z direction, guided by the third guide rail 311 and the fourth guide rail 312 (step S25).

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

[0287] Once the harvesting of the plant P on the right side is complete, a person or device applies a force in the Z direction to the right slat SL. Since the right slat SL and the left slat SL are independent, only the right slat SL receives the force in the Z direction. The right slat SL is slid in the Z direction, guided by the third guide rail 311 and the fourth guide rail 312 (step S27).

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

[0289] (4) Variations Regarding the modified version of the third embodiment, we will omit explanations of points that are the same as those of the third embodiment and focus on explaining the differences from the third embodiment.

Specifically, racks R are provided in inner I7 and inner I8, and plants P are cultivated in racks R. Since racks R are the same as in Modification 2B, their explanation is omitted.

[0295] The depth and width of structure 300A in modified example 3B are the same as those of structure 300A in modified example 3A, so their description is omitted. The height of structure 300A (in other words, the height between the front wall 310, the left wall 320, the right wall 330, and the rear wall 340) is a value that ensures D45 (not shown). D45 is the shortest distance in the Y direction from plant P to ceiling 350 when plant P has finished growing. D45 is preferably between 1 and 10 centimeters, but is not limited to this.

[0296] (4-3) Modification 3C Structures 300A and 300B may be installed inside the server room 40 instead of inside the greenhouse 10. Figure 71 is a schematic diagram showing the overall configuration of equipment 3 according to modified example 3C. Inside I7 and I8, instead of cultivating plants P, servers SV are installed. The workspace is the space necessary for server work.

[0297] The depth of structure 300A (in other words, the depth of ceiling 350) is such that D46 (not shown) and D47 (not shown) are ensured.

Figure 72 is a schematic diagram showing the overall configuration of equipment 3 according to modified example 3D. Inside I7 and I8, goods G are stored instead of plants P being cultivated. Specifically, racks R are provided inside I7 and I8, and goods G are stored in racks R. Since racks R are the same as in modified example 2D, their explanation is omitted. The workspace is the space necessary for warehouse work.

[0301] The depth and width of structure 300A are the same as in modified example 3A, so their description is omitted. The height of structure 300A (in other words, the height between the front wall 310, the left wall 320, the right wall 330, and the rear wall 340) is such that D51 (not shown) is ensured. D51 is the shortest distance in the Y direction from the goods G stored on the top shelf 180 of rack R to the ceiling 350. D51 is preferably between 5 and 10 centimeters, but is not limited to this.

In other words, the slat SL may slide along the third guide rail 311 and the fourth guide rail 312 by control of the control device.

[0307] <Fourth Embodiment> (1) Overall structure The overall configuration of the equipment 4 according to the fourth embodiment will now be described. Hereinafter, similarities between the first and fourth embodiments will be omitted, and the differences between the first and fourth embodiments will be the focus of the description. Figure 75 is a schematic diagram showing the overall configuration of the equipment 4 according to the fourth embodiment. Equipment 4 mainly comprises a greenhouse 10 and an air conditioner 11.

[0308] (1-1) Greenhouse The interior of the greenhouse 10 is mainly provided with structures 400A, 400B, 400C, and 400D. Structures 400A, 400B, 400C, and 400D divide the interior of the greenhouse 10 into the area inside structure 400A I10, the area inside structure 400B I11, the area inside structure 400C I12, the area inside structure 400D I13, and the area outside structures 400A, 400B, 400C, and 400D, which is the interior of the greenhouse 10. Details of structures 400A, 400B, 400C, and 400D will be described later.

[0309] In addition, facility 4 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 10.

[0310] (1-2) Air conditioner The air conditioner 11 is connected to the inner I10 by a hose 111. The air conditioner 11 is also connected to the inner I11 by another hose (not shown), to the inner I12 by another hose (not shown), and to the inner I13 by another hose (not shown). The air conditioned by the air conditioner 11 is supplied to the inner I10, inner I11, inner I12, and inner I13 via the hose 111 and so on.

[0311] (2) Detailed configuration The detailed configurations of structures 400A, 400B, 400C, and 400D will be described below. Structure 400A is a variable structure whose form can be changed by the operation of structure 400A. Structure 400B is a variable structure whose form can be changed by the operation of structure 400B. Structure 400C is a variable structure whose form can be changed by the operation of structure 400C. Structure 400D is a variable structure whose form can be changed by the operation of structure 400D.

[0312] The structure of structure 400A and the structure of structure 400B are approximately symmetric with respect to the planes extending in the Y and X directions. The structure of structure 400A and the structure of structure 400C are approximately symmetric with respect to the planes extending in the Y and Z directions. The structure of structure 400C and the structure of structure 400D are approximately symmetric with respect to the planes extending in the Y and X directions. The functions of structure 400A, structure 400B, structure 400C, and structure 400D are the same. The structure and function of structure 400A will be described below.

[0313] Figure 76 is a perspective view showing the detailed configuration of structure 400A. Figure 77 is a front view showing the detailed configuration of structure 400A. Figure 78 is a rear view showing the detailed configuration of structure 400A. Figure 79 is a left side view showing the detailed configuration of structure 400A. Figure 80 is a right side view showing the detailed configuration of structure 400A. Figure 81 is a top view showing the detailed configuration of structure 400A. In Figures 76, 77, 78, 79, 80, and 81, plant P is in a state where it has finished growing.

[0314] Structure 400A mainly consists of a front wall 410, a left side wall 420, a right side wall 430, a rear wall 440, a ceiling 450, and a rotating shaft AX.

[0315] The front wall 410 is an example of the first component and is erected approximately perpendicular to the floor F. The front wall 410 faces the passageway 102. The upper end of the front wall 410 is connected to the front end of the ceiling 450.

[0316] The left wall 420 faces the right wall 430 and is erected approximately perpendicular to the floor F. The left wall 420 is in contact with the front wall 410, the rear wall 440, and the ceiling 450. The left 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 interior I10 through the opening 421. The opening 421 is located approximately vertically below the approximate vertical center of the left wall 420. In other words, the opening 421 is located approximately vertically below the approximate vertical center of the structure 400A. The opening 421 is located behind the approximate 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 wall 420. The opening 421 may also be provided in the front wall 410, the right wall 430, the rear wall 440, and the ceiling 450 in addition to the left wall 420. The opening 421 may be provided approximately vertically above the approximate vertical center of the structure 400A. The opening 421 may also be provided in front of the approximate X-direction center of the structure 400A.

[0319] The right-side wall 430 faces the left-side wall 420 and is erected approximately 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 section. The opening 431 is located approximately vertically above the approximate vertical center of the right side wall 430. In other words, the opening 431 is located approximately vertically above the approximate vertical center of the structure 400A. The opening 431 is located forward of the approximate X-direction center of the structure 400A.

[0321] The air inside I10 is discharged from 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 inside I10 flows to the intake port of the air conditioner 11 via the opening 431 and the hose.

[0322] The opening 431 may be provided in the front wall 410, the left wall 420, the rear wall 440, or the ceiling 450 instead of the right wall 430. The opening 431 may also be provided in at least one of the front wall 410, the left wall 420, the rear wall 440, or the ceiling 450, in addition to the right wall 430. The opening 431 may be provided approximately vertically below the approximate vertical center of the structure 400A. The opening 431 may be provided behind the approximate X-direction center of the structure 400A. The opening 431 may be connected to a hose (not shown) that communicates with a location outside the greenhouse 10 other than the air intake of the air conditioner 11.

[0323] The rear wall 440 faces the front wall 410 and is erected approximately perpendicular to the floor F. The rear wall 440 is in contact with the left wall 420, the right wall 430, and the ceiling 450. The rear wall 440 is provided with a rotating member 441 and a fixed member 442.

[0324] The rotating member 441 is a member for fixing the ceiling 450 when the ceiling 450 is rotated. The rotating member 441 is provided approximately in the center of the rear wall 440 in the approximate Z direction and on the front side of the rear wall 440. The rotating member 441 is provided so as to be rotatable in a plane extending in the Y direction and Z direction, with the rotation center being approximately in the approximate center of the rotating member 441 in the approximate Y direction and approximately in the approximate center of the Z direction. Note that multiple rotating members 441 may be provided on the rear wall 440.

[0325] The fixing member 442 is a member for fixing the ceiling 450 when the ceiling 450 is rotated. The fixing member 442 is provided approximately in 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 be able to face the rotating member 441. Note that multiple 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 wall 420, the right wall 430, and the rear wall 440. The ceiling 450 can be moved by rotating it around the rotation axis AX. The ceiling 450 is rotatably mounted on a plane extending in the X and Y directions 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 around the rotation axis AX, the front wall 410 also rotates along with the ceiling 450. This changes the orientation of the front wall 410.

[0328] The area of ​​floor F facing ceiling 450 is enclosed by the front wall 410, left wall 420, right wall 430, rear wall 440, and ceiling 450, thereby forming the interior I10. Specifically, the front wall 410 encloses the front side of the area of ​​floor F where plants P are cultivated. The left wall 420 encloses the left side of the area of ​​floor F where plants P are cultivated. The right wall 430 encloses the right side of the area of ​​floor F where plants P are cultivated. The rear wall 440 encloses the rear side of the area of ​​floor F where plants P are cultivated. The ceiling 450 encloses the upper side of the area of ​​floor F where plants P are cultivated.

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

[0330] Plant P is cultivated in the inner area I10. Some of the bed F in the inner area I10 is filled with soil (not shown) in which plant P can be planted, or with a nutrient solution (not shown) in which plant P can be immersed. In the inner area I10, plant P is either planted in soil or immersed in nutrient solution. Note that the cultivation of plant P in the inner area I10 does not mean that plant P is always present in the inner area I10. After plant P is harvested, there may be no plant P in the inner area I10. Also, even if plant P is present in the inner area I10, it may not be visible to the naked eye because it has just been planted.

[0331] Examples of configurations for the front wall 410, left wall 420, right wall 430, rear wall 440, and ceiling 450 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and plastic film covering the frame, and a configuration in which the frame and the surface covering the frame 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 translucent vinyl, glass, or plastic film so that the light from the lighting in space I14 is transmitted to the interior 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 translucent, the plants P inside I10 are visible from the outside of the structure 400A.

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

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

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

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

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

[0338] The configuration of structure 400A shown in Figures 82, 83, 84, 85, 86, and 87 is a configuration in which the ceiling 450 is rotated around the rotation axis AX, compared to the configuration of structure 400A shown in Figures 76, 77, 78, 79, 80, and 81. The ceiling 450 is rotated by slightly less than 90 degrees in the planes extending in the X and Y directions, with the rotation axis AX as the center of rotation. Because the ceiling 450 is rotated, the front wall 410 is also rotated along with the ceiling 450.

[0339] The rotating member 441 is rotated by slightly less than 90 degrees in the planes extending in the Y and Z directions, with a rotation center approximately at the approximate center in both the Y and Z directions of the rotating member 441. The ceiling 450 is fixed by being sandwiched between the rotating member 441 on the front side of the ceiling 450 and the fixing 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 state rotated around the rotation axis AX.

[0340] The interior I10 of structure 400A is in communication with the exterior of structure 400A and passage 102 via the front and top. By changing the configuration of the ceiling 450 and front wall 410, the interior I10 of structure 400A is separated from the exterior and passage 102, and is now in communication with the exterior and passage 102. As a working space is secured, people or equipment performing agricultural work can perform agricultural work on plants P via the front and top of structure 400A.

[0341] Furthermore, the configuration of structure 400A in Figures 76, 77, 78, 79, 80, and 81 is also a configuration in which the ceiling 450 is rotated around the rotation axis AX, as seen in the configurations of structure 400A in Figures 82, 83, 84, 85, 86, and 87. The ceiling 450 is rotated by slightly less than 90 degrees in the planes extending in the X and Y directions, with the rotation axis AX as the center of rotation. Because the ceiling 450 is rotated, the front wall 410 is also rotated along with the ceiling 450.

[0342] The configuration of the ceiling 450 and the front wall 410 has been changed, altering the state from one in which the outside of the structure 400A and the passage 102 are connected to the inside I10, to one in which the outside of the structure 400A and the passage 102 are separated from the inside I10.

[0343] (3) Operation The operation of equipment 4 when a person or device performs harvesting work will be described. Since the operation of structures 400A, 400B, 400C, and 400D is the same, the operation of structure 400A will be described in detail. Figure 88 is a flowchart of the operation of equipment 4. Air heated by the air conditioner 11 is supplied to the inside I10 via a hose and opening 421. The configuration of structure 400A is shown in Figures 76, 77, 78, 79, 80, and 81.

[0344] The front wall 410 covers the front side of the structure 400A, and the ceiling 450 covers the top side of the structure 400A. Therefore, the outside of the structure 400A and the passage 102 are isolated 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 inside I10 is maintained higher than the temperature of the space I14. Therefore, the inside I10 is a suitable environment for cultivating plants P. The plants P are in a state suitable for harvesting.

[0345] A person or device moves from outside the greenhouse 10 into the greenhouse 10 via the entrance / exit 101. The person or device moves to the front passage 102 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 is rotated around the rotation axis AX by the forces in the Y direction and the negative X direction. Specifically, the ceiling 450 rotates in a plane extending in the X and Y directions with the rotation axis AX as the center of rotation. The front wall 410, which is connected to the ceiling 450, is also rotated along with the ceiling 450 (step S31).

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

[0347] A person or device rotates the rotating member 441. The rotating member 441 is rotated by slightly less than 90 degrees in the planes extending in the Y and Z directions, with the rotation center being approximately the center in both the Y and Z directions of the rotating member 441. The ceiling 450 is fixed between the rotating member 441 on the front side of the ceiling 450 and the fixing 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 configuration of the structure 400A can be changed in the configurations shown in Figures 82, 83, 84, 85, 86, and 87 (step S33).

[0348] The front and top of structure 400A connect the outside of structure 400A and the passage 102 to the inside I10. Since a working space has been secured, a person or equipment can perform harvesting work on plant P. The person or equipment begins harvesting work on plant P.

[0349] Once the harvesting is complete, a person or device rotates the rotating member 441. The rotating member 441 rotates by slightly less than 90 degrees in the planes extending in the Y and Z directions, with the rotation center being approximately the center in both the Y and Z directions of the rotating member 441. The ceiling 450 is released from being sandwiched between the rotating member 441 and the fixed member 442. The ceiling 450 is subjected to a force in the negative Y direction due to gravity. Therefore, the ceiling 450 rotates around the rotation axis AX. Specifically, the ceiling 450 rotates in the planes extending in the X and Y directions with the rotation axis AX as the rotation center. The front wall 410 connected to the ceiling 450 also rotates along with the ceiling 450 (step S34). Note that a person or device may apply forces in the negative Y and X directions to at least one of the front wall 410 and the ceiling 450.

[0350] As the front wall 410 and ceiling 450 continue to rotate, the front wall 410 will collide with the floor F. Upon colliding with the floor F, the front wall 410 will receive a force in the Y direction from the floor F. This will stop the rotation of the front wall 410 and ceiling 450. The ceiling 450 will have rotated by slightly less than 90 degrees in the planes 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 configuration of the structure 400A can be changed to the configurations shown in Figures 76, 77, 78, 79, 80, and 81 (step S35). The outside of the structure 400A and the passage 102 are separated from the inside I10.

[0352] (4) Features The variable structure further comprises a movable ceiling 450 that faces the interior floor F and is connected to the first component, and a rotating shaft AX provided along the end of the ceiling 450. When the ceiling 450 is rotated around the rotating shaft AX, the first component also rotates along with the ceiling 450, thereby changing the configuration of the first component.

[0353] The first component rotates in conjunction with the ceiling 450. The force applied to the first component is less likely to be dispersed in an unspecified direction. The first component operates in a constant direction by the rotation axis AX. Therefore, the variable structure allows the configuration of the first component to be easily changed by a person or device.

[0354] (5) Variant Regarding the modified version of the fourth embodiment, we will omit explanations of points that are the same as those of the fourth embodiment and focus on explaining the differences from the fourth embodiment.

Figure 90 is a schematic diagram showing the overall configuration of the equipment 4 according to Modification 4B. The structure 400A in Modification 4B is the same as the structure 400A in the fourth embodiment, so its description is omitted.

The width of structure 400A is the sum of the width of tank A and a value between 5 cm and 30 cm, but is not limited to this. The height of structure 400A is the sum of the height of tank A and a value between 5 cm and 30 cm, but is not limited to this.

[0372] (5-7) Modification 4G In the fourth embodiment and modified examples 4A, 4B, 4C, 4D, 4E, and 4F, the front wall 410 and ceiling 450 may be modified in appearance by control of a control device (not shown). In other words, the front wall 410 and ceiling 450 may be rotated about the rotation axis AX by control of the control device.

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

[0374] (1-1) Greenhouse The interior of the greenhouse 10 mainly consists of structure 500A and structure 500B. Structures 500A and 500B divide the interior of the greenhouse 10 into three areas: the area inside structure 500A I15, the area inside structure 500B I16, and the area outside structures 500A and 500B, which is the interior of the greenhouse 10. Details of structures 500A and 500B will be described later.

[0375] In addition, facility 5 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 10.

[0376] (1-2) Air conditioner The air conditioner 11 is connected to the inner I15 by a hose (not shown) and to the inner I16 by another hose (not shown). The air conditioned by the air conditioner 11 is supplied to the inner I15 and inner I16 via the hoses and the like.

[0377] (2) Detailed configuration The detailed configurations of structures 500A and 500B will now be described. Structure 500A is a variable structure whose configuration can be changed by the operation of structure 500A. Structure 500B is a variable structure whose configuration can be changed by the operation of structure 500B. The structure of structure 500A and the structure of structure 500B are substantially symmetric with respect to the planes extending in the Y and Z directions. The functions of structure 500A and structure 500B are the same. The structure and function of structure 500A will be described below.

[0378] Figure 96 is a perspective view showing the detailed configuration of structure 500A. Figure 97 is a front view showing the detailed configuration of structure 500A. Figure 98 is a rear view showing the detailed configuration of structure 500A. Figure 99 is a left side view showing the detailed configuration of structure 500A. Figure 100 is a right side view showing the detailed configuration of structure 500A. Figure 101 is a top view showing the detailed configuration of structure 500A. In Figures 96, 97, 98, 99, 100, and 101, plant P is in a state where it has finished growing.

[0379] Structure 500A mainly consists of 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 installed 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 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 is positioned opposite the third guide rail 511 and is installed 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 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 substantially perpendicular to the floor F. The two slats SL are guided by a third guide rail 511 and a 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 appearance of the front wall 510 is changed by the sliding of the two slats SL guided by the third guide rail 511 and the fourth guide rail 512.

[0383] Of the two slats SL that make up 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 slide 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 the first component and is erected approximately perpendicular to the floor F. The front wall 510 faces the passage 102. The left and right ends of the front wall 510 may be in contact with the vertical wall V. In other words, the left end of the left slat SL may be in contact with the vertical wall V. The right end of the right slat SL may be in contact with 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 350 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 interior I15 through the opening 551. The opening 551 is located to the left of the approximate center in the Z direction of the structure 500A. The opening 551 is also located behind the approximate center in the X direction of the structure 500A.

[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 in the Z direction of the structure 500A. The opening 551 may be provided in front of the approximate center in the X direction of the structure 500A.

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

[0389] The air inside I15 is discharged from 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 inside I15 flows to the intake port of the air conditioner 11 via 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 in the Z direction of the structure 500A. The opening 552 may be provided behind the approximate center in the X direction of the structure 500A.

[0391] The area of ​​floor F where plants P are cultivated is enclosed by the front wall 510, the ceiling 550, and the vertical walls V of the greenhouse 10, thereby forming the interior I15. Specifically, the front wall 510 encloses the front side of the area of ​​floor F where plants P are cultivated. The vertical walls V enclose the left, right, and rear sides of the area of ​​floor F where plants P are cultivated. The ceiling 550 encloses the upper side of the area of ​​floor F where plants P are cultivated.

[0392] The interior I15 is shielded 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 space between the interior I15 and the outside of the structure 500A and the passage 102 is 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 interior I15. Therefore, air supplied to the interior I15 through the opening 551 does not easily flow from the interior I15 to the outside of the structure 500A. Air in space I17 also does not easily flow into the interior I15. It is difficult for people or equipment to approach the interior I15. People or equipment cannot secure working space.

[0393] Plant P is cultivated in the inner area I15. Some of the bed F in the inner area I15 is filled with soil (not shown) in which plant P can be planted, or with a nutrient solution (not shown) in which plant P can be immersed. In the inner area I15, plant P is either planted in soil or immersed in nutrient solution. Note that the cultivation of plant P in the inner area I15 does not mean that plant P is always present in the inner area I15. After plant P is harvested, there may be no plant P in the inner area I15. Also, even if plant P is present in the inner area I15, it may not be visible to the naked eye because it has just been planted.

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

[0395] The front wall 510 (with two slats SL) and the ceiling 550 include transparent or translucent vinyl, glass, or plastic film so that light from the lighting in the space I17 can be transmitted to the interior I15. Because the front wall 510 (with two slats SL) and the ceiling 550 are transparent or translucent, the plants P inside I15 are visible from the outside of the structure 500A.

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

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

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

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

[0400] The structure 500A does not necessarily have to have a ceiling 550. In this case, the upper end of the front wall 510 is fixed in contact with the ceiling of the greenhouse 10. The area of ​​the floor F where the plants P are cultivated is enclosed by the front wall 510, the vertical walls V of the greenhouse 10, and the ceiling of the greenhouse 10, thereby forming the interior I15. Specifically, the front wall 510 encloses the front side of the area of ​​the floor F where the plants P are cultivated. The vertical walls V enclose the left, right, and rear sides of the area of ​​the floor F where the plants P are cultivated. The ceiling of the greenhouse 10 encloses the upper side of the area of ​​the floor F where the plants P are cultivated.

[0401] The structure 500A may also include a left wall, a right wall, or a rear wall. The area of ​​the floor F where the plants P are cultivated is enclosed by the front wall 510, the vertical wall V of the greenhouse 10, and one of the left wall, right wall, or rear wall, thereby forming the interior I15.

[0402] The following describes various aspects of structure 500A. Figure 102 is a perspective view showing the detailed configuration of structure 500A. Figure 103 is a front view showing the detailed configuration of structure 500A. Figure 104 is a rear view showing the detailed configuration of structure 500A. The aspects of structure 500A shown in Figures 102, 103, and 104 are the same as those shown in Figures 96, 97, 98, 99, 100, and 101, but with the left slat SL slid in the Z direction. In this case, the left side view, right side view, and plan view showing the detailed configuration of structure 500A are the same as those shown in Figures 99, 100, and 101, and are therefore omitted.

[0403] The left slat SL has slid in the Z direction, so it is roughly aligned with the right slat SL in the X direction. The inner I15 is connected to the outside of the structure 500A and the passage 102 via the left front side of the structure 500A. The configuration of the front wall 510 has been changed from a state where the outside of the structure 500A and the passage 102 were separated from the inner I15 to a state where the outside of the structure 500A and the passage 102 are connected to the inner I15. As a working space has been secured, a person or equipment performing agricultural work can perform agricultural work on the plants P via the front side of the structure 500A.

[0404] Figure 105 is a perspective view showing the detailed configuration of structure 500A. Figure 106 is a front view showing the detailed configuration of structure 500A. Figure 107 is a rear view showing the detailed configuration of structure 500A. The configuration of structure 500A in Figures 105, 106, and 107 is the same as that of structure 500A in Figures 96, 97, 98, 99, 100, and 101, but with the right slat SL slid in the minus Z direction. In this case, the left side view, right side view, and plan view showing the detailed configuration of structure 500A are the same as those in Figures 99, 100, and 101, and are therefore omitted.

[0405] The right slat SL has been slid in the negative Z direction, so it is roughly aligned with the left slat SL in the X direction. The inner I15 is connected to the outside of the structure 500A and the passage 102 via the right front side of the structure 500A. The configuration of the front wall 510 has been changed from a state where the outside of the structure 500A and the passage 102 were blocked from the inner I15 to a state where the outside of the structure 500A and the passage 102 are connected to the inner I15. As a working space has been secured, a person or equipment performing agricultural work can perform agricultural work on the plants P via the front side of the structure 500A.

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

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

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

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

[0410] A person or device moves from outside the greenhouse 10 into the greenhouse 10 via the entrance / exit 101. The person or device moves to the passage 102 in front of the structure 500A. The person or device applies a force in the Z direction to the left of the two slats SL. Since 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 slid in the Z direction, guided by the third guide rail 511 and the fourth guide rail 512 (step S41).

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

[0412] Once the harvesting of the plant P on the left is complete, a person or device applies a force in the negative Z direction to the left slat SL. Since 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 slid in the negative Z direction, guided by the third guide rail 511 and the fourth guide rail 512 (step S43).

[0413] As the left slat SL is slid in the negative Z direction, the configuration of structure 500A is changed to the configuration of structure 500A in Figures 96, 97, 98, 99, 100, and 101 (step S44). The configuration of the front wall 510 in Figure 103 is changed to the configuration of the front wall 510 in Figure 97. As the left front side of structure 500A is covered by the left slat SL, the outside of structure 500A and the passage 102 are separated 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. Since 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 slid in the negative Z direction, guided by the third guide rail 511 and the fourth guide rail 512 (step S45).

[0415] As the right slat SL is slid in the -Z direction, the right slat SL is roughly aligned with the left slat SL in the X direction. The configuration of structure 500A is changed to the configuration of structure 500A in Figures 105, 106, and 107 (step S46). The configuration of the front wall 510 in Figure 97 is changed to the configuration of the front wall 510 in Figure 106. The right front side of structure 500A connects the outside of structure 500A and the passage 102 with the inside I15. As working space is secured, a person or device can perform harvesting work on the plant P on the right side. The person or device begins harvesting work on the plant P on the right side.

[0416] Once the harvesting of the plant P on the right side is complete, a person or device applies a force in the Z direction to the right slat SL. Since the right slat SL and the left slat SL are independent, only the right slat SL receives the force in the Z direction. The right slat SL is slid in the Z direction, guided by the third guide rail 511 and the fourth guide rail 512 (step S47).

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

[0418] (4) Features The variable structure is formed by the interior I15 and interior I16 enclosing an area of ​​the interior floor F where plants P are cultivated, with at least one of the first component, the vertical wall V of the other structure, and the ceiling of the other structure.

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

[0420] (5) Variant Regarding the modified version of the fifth embodiment, we will omit explanations of points that are the same as those of the fifth embodiment and focus on explaining the differences from the fifth embodiment.

[0421] (5-1) Modification 5A (5-1-1) Composition Structures 500A and 500B may be installed inside the mushroom cultivation facility 20 instead of inside the greenhouse 10. Figure 109 is a schematic diagram showing the overall configuration of the equipment 5 according to modified example 5A. Inside I15 and I16, mushrooms M are cultivated instead of plants P. Specifically, racks R are provided inside I15 and I16, and mushrooms M are cultivated on racks R. Since racks R are the same as in modified example 3A, their explanation is omitted. The workspace is the space necessary for mushroom cultivation.

[0422] The depth of structure 500A (in other words, the depth of ceiling 550) is such that D74 (not shown) is ensured. D74 is the shortest distance in the X direction from base 180 to front wall 510. D74 is preferably between 1 and 5 centimeters, but is not limited to this.

[0423] The height of structure 500A (in other words, the height of the front wall 510) is such that D75 (not shown) is ensured. D75 is the shortest distance in the Y direction from the uppermost base 180 mushroom M to the ceiling 550 when the mushroom M has finished growing. D75 is preferably between 1 and 10 centimeters, but is not limited to this.

[0424] The width of structure 300A (in other words, the width between the front wall 510 and the ceiling 550) is the same as the width inside greenhouse 10.

[0425] (5-1-2) Characteristics The variable structure is formed by the interior I15 and interior I16 enclosing, at least, the first component, the vertical wall V of the other structure, and the ceiling of the other structure, an area of ​​the interior floor F where the mushroom M is cultivated.

[0426] Because other structures, such as vertical walls V, surround the area of ​​floor F, the variable structure can surround the area of ​​floor F with fewer components. Therefore, the variable structure can achieve energy savings in mushroom cultivation and reduce the cost of cultivating mushrooms M with fewer components.

[0427] (5-2) Modification 5B Structures 500A and 500B may be installed inside the plant factory 30 instead of inside the greenhouse 10. Figure 110 is a schematic diagram showing the overall configuration of the equipment 5 according to Modification 5B. Plants P are cultivated in the inner I15 and inner I16. Specifically, racks R are provided in the inner I15 and inner I16, and plants P are cultivated in the racks R. The racks R are the same as in Modification 3B, so their explanation is omitted.

[0428] The depth and width of structure 500A in Modification 5B are the same as those of structure 500A in Modification 5A, so their explanation is omitted. The height of structure 500A (in other words, the height of the front wall 510) is a value that ensures D76 (not shown). D76 is the shortest distance in the Y direction from plant P to ceiling 550 when plant P has finished growing. D76 is preferably between 1 and 10 centimeters, but is not limited to this.

[0429] (5-3) Modification 5C (5-3-1) Composition Structures 500A and 500B may be installed inside the server room 40 instead of inside the greenhouse 10. Figure 111 is a schematic diagram showing the overall configuration of the equipment 5 according to modified example 5C. Inside I15 and I16, instead of cultivating plants P, servers SV are installed. The workspace is the space necessary for server work.

[0430] The depth of structure 500A (in other words, the depth of ceiling 550) is such that D77 (not shown) is ensured. D77 is the shortest distance in the X direction from server SV to front wall 510. D77 is preferably between 5 and 20 centimeters, but is not limited to this.

[0431] The height of structure 500A (in other words, the height of the front wall 510) is such that D78 (not shown) is ensured. D78 is the shortest distance in the Y direction from server SV to ceiling 550. D78 is preferably between 5 and 20 centimeters, but is not limited to this.

[0432] The width of structure 500A (in other words, the width between the front wall 510 and the ceiling 550) is the same as the width inside greenhouse 10.

[0433] (5-3-2) Characteristics The variable structure is formed by the inner I15 and inner I16 enclosing, at least, the first component, the vertical wall V of the other structure, and the ceiling of the other structure, the area of ​​the internal floor F where the server SV is installed.

[0434] Because other structural elements such as vertical walls V 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 server SV operation and reduce the costs associated with server SV operation with fewer components.

[0435] (5-4) Modification 5D (5-4-1) Composition Structures 500A and 500B may be installed inside the warehouse 50 instead of inside the greenhouse 10. Figure 112 is a schematic diagram showing the overall configuration of the equipment 5 according to modified example 5D. Inside I15 and I16, instead of cultivating plants P, goods G are stored. Specifically, racks R are provided inside I15 and I16, and goods G are stored in racks R. Since racks R are the same as in modified example 3D, their explanation is omitted. The workspace is the space necessary for warehouse work.

[0436] The depth and width of structure 500A are the same as in modified example 5A, so their description is omitted. The height of structure 500A (in other words, the height of the front wall 510) is a value that ensures D79 (not shown). D79 is the shortest distance in the Y direction from the goods G stored on the top shelf 180 of rack R to the ceiling 550. D79 is preferably between 5 and 10 centimeters, but is not limited to this.

[0437] (5-4-2) Characteristics The variable structure is formed by the interior I15 and interior I16 enclosing an area of ​​the interior floor F where the goods G are stored, with at least one of the first component, the vertical wall V of the other structure, and the ceiling of the other structure.
