[0013] <Current Situation> In recent years, structures have been used in which plants or mushrooms are cultivated, livestock are raised, aquatic organisms are farmed, products are stored, or servers are installed. To maintain a predetermined environment (temperature, humidity, etc.) inside the structure where the plants or mushrooms, livestock, aquatic organisms, products, and servers reside, air conditioning is performed for the interior of the structure. This has resulted in a problem in that a large amount of energy is used for air conditioning the interior of the structure. Below, an embodiment of an example of a variable structure that contributes to solving the above problem will be described.

[0014] In the following embodiments, front means the X direction, rear means the minus X direction, left means the minus Z direction, right means the Z direction, bottom means the minus Y direction, and top means the Y direction. Depth is the length in the X direction. Width is the length in the Z direction. Height is the distance from the ground or floor in the Y direction.

[0015] In the following embodiments, the ground or floor is approximately horizontal. Therefore, being approximately perpendicular to the ground or floor is approximately vertical. Being approximately parallel to the ground or floor is approximately horizontal. A perspective view is a view from diagonally above. A front view is a view from the front. A rear view is a view from the rear. A left side view is a view from the left. A right side view is a view from the right. A plan view is a view from above.

[0016] In the following embodiments, structures include buildings and structures. A building is a structure fixed to the ground that has a roof and pillars or walls. A structure is an artificial object fixed to the ground. A "hose" is a general term for a passage that carries a fluid such as air, and includes so-called "ducts" and "air passages." An "air passage" includes an air passage under the floor, an air passage above the ceiling, an air passage behind a wall, etc.

[0017] In the following embodiments, the plane component may be a component of a curved surface that is entirely or partially curved. Blocking includes not only complete obstruction but also making it difficult to pass through. For example, blocking A and B includes making it difficult to pass from B to A because a wall covers the area between A and B.

[0018] In the following embodiments, the fact that a plant is being cultivated does not necessarily mean that the plant is always present. The fact that a plant is being cultivated includes the case where the plant is not present after being harvested. The fact that a plant is being cultivated also includes the case where the plant is present but cannot be seen with the naked eye. The state of the plant depicted in the drawings is that of a plant that has finished growing.

[0019] In the following embodiments, the vinyl greenhouse may be a greenhouse (glass greenhouse, plastic film greenhouse, etc.). The vinyl greenhouse may or may not be a building.

[0020] <First embodiment> (1) Overall configuration The overall configuration of the facility 1 according to the first embodiment will be described. Fig. 1 is a schematic diagram showing the overall configuration of the facility 1. The facility 1 mainly includes a greenhouse 10 and an air conditioner 11.

[0021] (1-1) Vinyl greenhouse The vinyl greenhouse 10 is a structure in which a framework is assembled and the top is covered with vinyl or the like in order to cultivate plants P. Plants P are cultivated inside the vinyl greenhouse 10.

[0022] The greenhouse 10 mainly comprises a structure 100A and a structure 100B. The interior of the greenhouse 10 is divided into an inside I1 of the structure 100A, an inside I2 of the structure 100B, and a space I3. The space I3 is outside the structures 100A and 100B and is inside the greenhouse 10. Details of the structures 100A and 100B will be described later. The greenhouse 10 mainly comprises an entrance / exit 101, a passage 102, and one or more lights (not shown).

[0023] (1-1-1) Entrance / Exit The entrance / exit 101 is an entrance through which people or equipment planning to perform agricultural work move from the outside of the greenhouse 10 to the inside of the greenhouse 10. The entrance / exit 101 is also an exit through which people or equipment that have completed agricultural work move from the inside of the greenhouse 10 to the outside of the greenhouse 10. The entrance / exit 101 may have an openable / closable structure (opening) or an open structure (opening). The greenhouse 10 may have multiple entrances / exits 101.

[0024] Agricultural work is work performed by a person or machine on a plant P. Examples of agricultural work include sowing work, which is the work of planting seeds or seedlings of the plant P, cultivation work, which is work performed to grow the plant P (watering, spraying pesticides, pruning, spreading fertilizer, insect repellent, etc.), harvesting work, which is the work of harvesting all or part of the plant P, soil work, which is the work of preparing the soil and plowing, nutrient solution work, which is the work of storing or exchanging nutrient solution, and other agricultural work.

[0025] (1-1-2) Passageway The passageway 102 is a passageway used by people or equipment when agricultural work is being carried out, and is a passageway outside the structure 100A and the structure 100B.

[0026] (1-2) Air Conditioner The air conditioner 11 conditions the air in the inside I1 and the inside I2. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. The air conditioner 11 communicates with the inside I1 via a hose 111. The air conditioner 11 also communicates with the inside I2 via a hose (not shown) different from the hose 111. Air conditioned by the air conditioner 11 is supplied to the inside I1 and the inside I2 via the hose 111 or the like.

[0027] 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 inside I1, the inside I2, and the space I3.

[0028] (2) Detailed Configuration The detailed configuration of the structure 100A and the structure 100B will be described. The structure 100A is a variable structure whose configuration can be changed by the operation of the structure 100A. The structure 100B is a variable structure whose configuration can be changed by the operation of the structure 100B. A variable structure is a structure whose configuration can be changed. The structures of the structure 100A and the structure 100B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 100A and the structure 100B are similar. The structure and function of the structure 100A will be described below.

[0029] Fig. 2 is a perspective view showing the detailed configuration of the structure 100A. Fig. 3 is a front view showing the detailed configuration of the structure 100A. Fig. 4 is a rear view showing the detailed configuration of the structure 100A. Fig. 5 is a left side view showing the detailed configuration of the structure 100A. Fig. 6 is a right side view showing the detailed configuration of the structure 100A. Fig. 7 is a plan view showing the detailed configuration of the structure 100A.

[0030] The structure 100A mainly has 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. The first guide rail 112 and the second guide rail 113 are arranged to face each other.

[0031] The front wall 110 is mainly composed of a plurality of slats SL. For example, the front wall 110 is mainly composed of nine slats SL. The slats SL are connected to 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 configuration of the front wall 110 can be changed by the slats SL sliding while being guided by the first guide rail 112 and the second guide rail 113.

[0032] The front wall 110 is an example of a first component and faces the aisle 102. The case 114 houses the slats SL that are slid in the Y direction. The case 114 is provided so as to be able to house all of the slats SL that constitute the front wall 110. The case 114 may also be provided on the underside of the front wall 110.

[0033] The left side wall 120 faces the right side wall 130 and is in contact with the front wall 110, the rear wall 140, and the ceiling 150. An opening 121 that communicates with the hose 111 is provided in the left side wall 120.

[0034] The opening 121 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the inside I1 through the opening 121. The opening 121 is provided approximately vertically below the approximately vertical center of the structure 100A.

[0035] The opening 121 may be provided in any one of the front wall 110, the right wall 130, the rear wall 140, or the ceiling 150, instead of the left side wall 120. The opening 121 may be provided in at least one of the front wall 110, the right side wall 130, the rear wall 140, or the ceiling 150, in addition to the left side wall 120. The opening 121 may be provided approximately vertically above the approximately vertical center of the structure 100A. The opening 121 may be provided forward of the approximately X-direction center of the structure 100A.

[0036] The right side wall 130 faces the left side wall 120 and 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.

[0037] The opening 131 is an example of a discharge portion. The opening 131 is provided in the right side wall 130, which faces the left side wall 120 in which the opening 121 is provided. The opening 131 is provided substantially vertically above the substantially vertical center of the structure 100A.

[0038] The air inside I1 is discharged from the 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 into the intake port of the air conditioner 11 via the opening 131 and the hose.

[0039] The opening 131 may be provided in any of the front wall 110, the left wall 120, the rear wall 140, or the ceiling 150, instead of the right side wall 130. The opening 131 may be provided in at least one of the front wall 110, the left side wall 120, the rear wall 140, or the ceiling 150, in addition to the right side wall 130. The opening 131 may be provided approximately vertically below the approximately vertical center of the structure 100A. The opening 131 may be provided rearward of the approximately X-direction center of the structure 100A. The opening 131 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air intake of the air conditioner 11.

[0040] The rear wall 140 faces the front wall 110 and is in contact with the left side wall 120, the right side wall 130, and the ceiling 150. The ceiling 150 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.

[0041] The area of ​​floor F facing ceiling 150 is surrounded by front wall 110, left wall 120, right wall 130, rear wall 140, and ceiling 150, thereby forming inside I1. Specifically, front wall 110 surrounds the front side of the area of ​​floor F where plants P are grown. Left wall 120 surrounds the left side of the area of ​​floor F where plants P are grown. Right wall 130 surrounds the right side of the area of ​​floor F where plants P are grown. Rear wall 140 surrounds the rear side of the area of ​​floor F where plants P are grown. Ceiling 150 surrounds the upper side of the area of ​​floor F where plants P are grown.

[0042] The inside I1 is isolated from the outside of the structure 100A and the passage 102 by the front wall 110, left side wall 120, right side wall 130, rear wall 140, and ceiling 150. The space between the inside I1, the outside of the structure 100A, and the passage 102 is covered by the front wall 110, left side wall 120, right side wall 130, rear wall 140, and ceiling 150. It is difficult for people, equipment, and air to pass from the outside of the structure 100A and the passage 102 to the inside I1. Therefore, air supplied to the inside I1 through the opening 121 is unlikely to flow from the inside I1 to the outside of the structure 100A. Air in space I3 is also unlikely to flow to the inside I1. It is difficult for people or equipment to access the inside I1. People or equipment cannot secure work space. Work space is the space necessary for agricultural work.

[0043] Plants P are grown in the inner side I1. A part or all of the floor F in the inner side I1 is filled with soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I1, the plants P are planted in soil or immersed in the nutrient solution.

[0044] Examples of configurations of the left side wall 120, the right side wall 130, the rear wall 140, the ceiling 150, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0045] The front wall 110 (nine slats SL), the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I3 is transmitted to the inside I1. Because the front wall 110 (nine slats SL), the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 are transparent or semi-transparent, the plants P on the inside I1 can be seen through from the outside of the structure 100A.

[0046] The depth of the structure 100A is a value that ensures D1 and D2. D1 is the shortest distance in the X direction from the plant P to the front wall 110 when the plant P has finished growing. D1 is preferably 1 to 10 centimeters, but is not limited to this. D2 is the shortest distance in the negative X direction from the plant P to the rear wall 140 when the plant P has finished growing. D2 is preferably 1 to 10 centimeters, but is not limited to this.

[0047] The height of the structure 100A is a value that ensures D3, which is the shortest distance in the Y direction from the plant P to the ceiling 150 when the plant P has finished growing. D3 is preferably, but not limited to, 1 to 10 centimeters.

[0048] The width of the structure 100A is a value that ensures D4 and D5. D4 is the shortest distance in the negative Z direction from the plant P to the left side wall 120 when the plant P has finished growing. D4 is preferably, but not limited to, 1 to 10 centimeters. D5 is the shortest distance in the Z direction from the plant P to the right side wall 130 when the plant P has finished growing. D5 is preferably, but not limited to, 1 to 10 centimeters.

[0049] The left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 are components whose configuration cannot be changed. The front wall 110 is a component whose configuration can be changed. Therefore, the structure 100A is a variable structure. Note that at least one of the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 may be a component whose configuration can be changed. Various configurations of the structure 100A will be described below.

[0050] FIG. 8 is a perspective view showing the detailed configuration of the structure 100A. The configuration shown in FIG. 8 is one in which the slats SL have been slid in the Y direction from the configurations shown in FIGS. 2, 3, 4, 5, 6, and 7. Of the nine slats SL, five slats SL are housed in a case 114. The front side of the structure 100A connects the outside of the structure 100A and the passage 102 to the inside I1. By changing the configuration of the front wall 110, the outside of the structure 100A, the passage 102, and the inside I1 are now connected to the inside I1, rather than being isolated from the inside I1. Because a work space is secured, a person or device can perform agricultural work on plants P through the front side of the structure 100A.

[0051] Figure 9 is a perspective view showing the detailed configuration of the structure 100A. In the state shown in Figure 9, the slats SL are slid in the Y direction from the state shown in Figure 8. The nine slats SL are housed in a case 114. The outside and passage 102 of the structure 100A communicate with the inside I1 through the front side of the structure 100A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 100A.

[0052] The state in Fig. 8 is also a state in which the slat SL has been slid in the minus Y direction from the state of the structure 100A in Fig. 9. The states in Figs. 2, 3, 4, 5, 6, and 7 are also states in which the slat SL has been slid in the minus Y direction from the state of Fig. 8. By changing the state of the front wall 110, a state in which the outside of the structure 100A and the passage 102 are connected to the inside I1 is changed to a state in which the outside of the structure 100A and the passage 102 are connected to the inside I1.

[0053] (3) Operation The operation of the equipment 1 when a person or device performs harvesting work will be described. Since the operation of the structure 100A and the operation of the structure 100B are similar, the operation of the structure 100A will be mainly described. Figure 10 is a flowchart showing the operation of the equipment 1. Air heated by the air conditioner 11 is supplied to the inside I1 through the hose 111 and the opening 121. The structure 100A has the configurations shown in Figures 2, 3, 4, 5, 6, and 7.

[0054] The front wall 110 (nine slats SL) covers the front side of the structure 100A. Therefore, the outside of the structure 100A and the passage 102 are separated from the inside I1. The heated air supplied to the inside I1 does not easily flow to the outside of the structure 100A. The temperature of the inside I1 is maintained higher than the temperature of the space I3. Therefore, the inside I1 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting (a state where they have finished growing). No working space is provided.

[0055] A person or device moves from outside the greenhouse 10 into the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 at the front of the structure 100A. The person or device applies a force in the Y direction to one or more slats SL. Because the slats SL are connected to adjacent slats SL, the force in the Y direction is transmitted to the nine slats SL. Therefore, the nine slats SL are guided by the first guide rail 112 and the second guide rail 113 and slide in the Y direction (step S1).

[0056] As the slats SL slide in the Y direction, the nine slats SL are stored in the case 114, starting with the uppermost slat SL. When the five slats SL are stored in the case 114, the state of the structure 100A is changed to the state shown in Fig. 8 (step S2). A person or a device continues to apply a force in the Y direction to one or more slats SL.

[0057] As the slats SL slide in the Y direction, the nine slats SL are stored in the case 114. The structure 100A is changed to the state shown in FIG. 9 (step S3). The front side of the structure 100A connects the outside of the structure 100A and the passage 102 with the inside I1. Now that a working space has been secured, a person or device can perform harvesting work on the plants P. The person or device begins harvesting work on the plants P.

[0058] When the harvesting work is completed, a person or device applies a force in the negative Y direction to one or more of the nine slats SL stored in the case 114. Because the slats SL are connected to adjacent slats SL, the force in the negative Y direction is transmitted to the nine slats SL. Therefore, the nine slats SL are guided by the first guide rail 112 and the second guide rail 113 and slide in the negative Y direction (step S4).

[0059] The slats SL are lowered below the case 114. When the four slats SL are lowered from the case 114, the state of the structure 100A is changed to the state shown in Fig. 8 (step S5). A person or a device then applies a force in the negative Y direction to one or more slats SL. The nine slats SL are guided by the first guide rail 112 and the second guide rail 113 and slide in the negative Y direction.

[0060] When the nine slats SL are lowered from the case 114, the structure 100A is transformed into the state shown in Figures 2, 3, 4, 5, 6, and 7 (step S6). The front side of the structure 100A is covered by the nine slats SL. Therefore, the outside of the structure 100A and the passage 102 are isolated from the inside I1.

The height of the structure 100A is the height of the person performing the aquaculture work plus 10 cm to 30 cm, but is not limited to this.

[0095] (4-9) Modification 1I The front wall 110 of the first embodiment and modifications 1A, 1B, 1C, 1D, 1E, 1F, 1G, and 1H may be modified by 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 the control device.

[0096] (5) Features (5-1) A variable structure is provided inside another structure. In the insides I1 and I2, plants P or mushrooms M are cultivated, livestock L are raised, aquatic organisms Q are farmed, merchandise G is stored, or a server SV is installed. The variable structure has a first component whose configuration can be changed. By changing the configuration of the first component, a state in which the outside of the variable structure is isolated from the insides I1 and I2 can be changed to a state in which the outside is connected to the insides I1 and I2.

[0097] When plants are grown inside a structure, the interior of the structure is air-conditioned to create an environment suitable for plant cultivation. The amount of energy required for air conditioning correlates with the volume of the structure's interior. Because plant cultivation requires work on the plants, the space required for work is secured inside the structure. In non-variable structures whose configuration cannot be changed, the space required for work is secured even when no work is being performed. Therefore, unnecessary space is air-conditioned during times when no work is being performed. This increases the amount of energy required for plant cultivation inside the structure, leading to increased costs for plant cultivation.

[0098] The variable structure is installed inside another structure, and on the insides I1 and I2, plants P or mushrooms M are cultivated, livestock L are raised, aquatic organisms Q are farmed, merchandise G is stored, or a server SV is installed. The variable structure can reduce the target of air conditioning from the inside of the other structure to the insides I1 and I2. Therefore, the variable structure can achieve energy savings in the cultivation of plants P, etc., and can reduce the costs associated with the cultivation of plants P, etc.

[0099] The state in which the outside of the variable structure is isolated from the insides I1 and I2 can be changed to a state in which the outside of the variable structure is connected to the insides I1 and I2. The state in which no working space is secured can be changed to a state in which a working space is secured. Therefore, the variable structure allows people or equipment to work on plants P, etc. on the insides I1 and I2.

[0100] When the configuration of a structure can be changed, the structure may be vulnerable to physical external forces. As a result, the structure may be damaged by external forces such as strong winds or typhoons, or external forces such as accumulated snow. A variable structure is installed inside another structure. As a result, the variable structure can protect plants P and the like from physical external forces. Furthermore, the inside I1 and the inside I2 are doubly insulated from the outside. As a result, the variable structure can achieve energy savings in the cultivation of plants P, etc., and reduce the costs associated with the cultivation of plants P, etc.

[0101] (5-2) In the variable structure, the first component faces the outer passage 102. The passage 102 is used by people or equipment when the people or equipment work on any of the plants P or mushrooms M, the livestock L, the aquatic organisms Q, the products G, or the server SV. By changing the configuration of the first component, the passage 102 can be changed from a state in which the passage 102 is blocked from the insides I1 and I2 to a state in which the passage 102 is connected to the insides I1 and I2.

[0102] The first component is more likely to receive force from a person or device on the passage 102. Therefore, the variable structure allows a person or device to easily change the state of the first component. The variable structure also makes it easier for a person or device to access the plant P, etc. from the passage 102. Therefore, the variable structure makes it easier for a person or device to work on the plant P, etc.

[0103] (5-3) The first component of the variable structure is a front wall 110 that is erected on an internal floor F. The variable structure further includes a ceiling 150 that faces the floor F and is in contact with the front wall 110, a rear wall 140 that faces the floor F, faces the front wall 110, and is in contact with the ceiling 150, a left side wall 120 that faces the floor F and is in contact with the front wall 110, the ceiling 150, and the rear wall 140, and a right side wall 130 that faces the floor F, faces the left side wall 120, and is in contact with the front wall 110, the ceiling 150, and the rear wall 140. The area of ​​the floor F that faces the ceiling 150 is surrounded 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 insides I1 and I2.

[0104] The variable structure can enclose the area of ​​the floor F and form the insides I1 and I2 without having any components on the bottom surface facing the ceiling 150. The variable structure can be installed after the fact 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 required for installation.

[0105] (5-4) The variable structure is further provided with a supply unit for supplying conditioned air from the outer air conditioner 11 to the inner sides I1 and I2. Therefore, the variable structure can air-condition the inner sides I1 and I2 using the supply unit, even if air conditioners are not provided on the inner sides I1 and I2. Furthermore, because the variable structure does not require air conditioners on the inner sides I1 and I2, the inner sides I1 and I2 can be used more widely for cultivating plants P, etc.

[0106] (5-5) In the variable structure, the supply unit is located approximately vertically below the center of the variable structure in the vertical direction. To create an environment suitable for growing plants, the space where the plants are located may be heated or humidified. Heated air is lighter than unheated air, so it moves from bottom to top. Humidified air is also lighter than unhumidified air, so it moves from bottom to top.

[0107] The variable structure has a supply unit located approximately vertically below the approximate vertical center of the variable structure. When heated air or humidified air is supplied to the supply unit, the heated air or humidified air moves from approximately vertically below to approximately vertically above. The variable structure creates airflow on the insides I1 and I2, making it less likely that temperature or humidity variations will occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for growing plants P, etc.

[0108] (5-6) The variable structure is further provided with an exhaust section for exhausting the air inside the insides I1 and I2 from the insides I1 and I2 to the outside. Because air is supplied to the inside of the structure, the air inside the structure may be exhausted through gaps in the structure. In this case, the air may not be smoothly exhausted, causing a problem of an increase in the air pressure inside. Also, a problem of gaps in the structure opening up over time may occur. Furthermore, the flow of air inside the structure may become random depending on the location of the gaps in the structure, resulting in uneven temperature or humidity.

[0109] The variable structure discharges the air inside I1 and I2 from inside I1 and inside I2 to the outside of the variable structure. Therefore, the variable structure can keep the air pressure and airflow inside I1 and inside I2 stable. Also, the variable structure can maintain its airtightness for a longer period of time.

[0110] (5-7) In a variable structure, the exhaust section is provided in a component of the variable structure that faces the component of the variable structure in which the supply section is provided. An opening from the inside to the outside of the structure may be provided near an opening from the outside to the inside of the structure. In this case, air supplied from the outside to the inside of the structure may be immediately exhausted from the inside to the outside of the structure. Therefore, temperature or humidity unevenness may occur between the vicinity of the opening from the outside to the inside of the structure and the distant area.

[0111] The variable structure has an exhaust section provided in a component of the variable structure that faces the component of the variable structure in which the supply section is provided. The variable structure creates airflow on the insides I1 and I2, making it difficult for temperature or humidity variations to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for growing plants P, etc.

[0112] (5-8) In the variable structure, when the supply section is provided substantially vertically below the substantially vertical center of the variable structure, the discharge section is provided substantially vertically above the substantially vertical center of the variable structure.

[0113] The variable structure creates airflow on the insides I1 and I2, making it difficult for temperature or humidity variations to occur on the insides I1 and I2. As a result, the variable structure makes the insides I1 and I2 an environment more suitable for growing plants P, etc.

[0114] (5-9) The discharge section of the variable structure is connected to a hose that is connected to the intake port of the air conditioner 11. Air supplied from the air conditioner 11 to the inside I1 and the inside I2 via the supply section is discharged again to the intake port of the air conditioner 11. Air circulating between the air conditioner 11 and the inside I1 and the inside I2 is less likely to flow into the space I3. The air conditioner 11 can limit the air that is the target of air conditioning to the air circulating between the air conditioner 11 and the inside I1 and the inside I2. Therefore, the variable structure can achieve energy savings in the cultivation of plants P, etc., and can reduce the costs associated with the cultivation of plants P, etc.

[0115] (5-10) The supply unit of the variable structure is located approximately vertically above the center of the variable structure in the vertical direction. To create an environment suitable for server operation, etc., the space where the server is installed may be air-conditioned or dehumidified. Since cooled air is heavier than uncooled air, it moves from top to bottom. Similarly, since dehumidified air is heavier than undehumidified air, it also moves from top to bottom.

[0116] The variable structure has a supply unit located approximately vertically above the approximate vertical center of the variable structure. When cooled air or dehumidified air is supplied to the supply unit, the cooled air or dehumidified air moves from approximately vertically above to approximately vertically below. The variable structure creates airflow on the insides I1 and I2, making it less likely that temperature or humidity variations will occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for operating the server SV, etc.

[0117] (5-11) In the variable structure, when the supply section is provided substantially vertically above the center of the variable structure in the vertical direction, the discharge section is provided substantially vertically below the center of the variable structure in the vertical direction.

[0118] The variable structure creates airflow on the insides I1 and I2, making it difficult for temperature or humidity variations to occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 environments more suitable for operating the server SV, etc.

Below, similarities between the first and second embodiments will be omitted, and differences between the first and second embodiments will be mainly described.

Air conditioned by the air conditioner 11 is supplied to the insides I4 and I5 via the hoses 115 and 116, etc.

[0122] (2) Detailed Configuration The detailed configuration of the structure 200A and the structure 200B will be described. The structure 200A is a variable structure that can change the state of the structure 200A by operating the structure 200A. The structure 200B is a variable structure that can change the state of the structure 200B by operating the structure 200B. The structures of the structure 200A and the structure 200B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 200A and the structure 200B are similar. The structure and function of the structure 200A will be described below.

[0123] Fig. 32 is a perspective view showing the detailed configuration of structure 200A. Fig. 33 is a front view showing the detailed configuration of structure 200A. Fig. 34 is a rear view showing the detailed configuration of structure 200A. Fig. 35 is a left side view showing the detailed configuration of structure 200A. Fig. 36 is a right side view showing the detailed configuration of structure 200A. Fig. 37 is a plan view showing the detailed configuration of structure 200A.

[0124] The structure 200A mainly has 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. The third guide rail 211 and the fourth guide rail 212 are arranged to face each other.

[0125] The front wall 210 is mainly composed of a plurality of slats SL. For example, the front wall 210 is mainly composed of 14 slats SL. The slats SL are connected to adjacent slats SL. The slats SL are approximately perpendicular to the floor F. The slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and can slide in the Z direction or the negative Z direction (the direction in which the third guide rail 211 and the fourth guide rail 212 extend). The configuration of the front wall 210 can be changed by the slats SL sliding while being guided by the third guide rail 211 and the fourth guide rail 212.

[0126] The front wall 210 is an example of a first component and faces the aisle 102. The 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. The case 213 houses the slats SL that are slid in the Z direction. The case 213 is provided so as to be able to house all of the slats SL that constitute the front wall 210. The case 213 may also be provided on the left side of the front wall 210.

[0127] Left side wall 220 faces right side wall 230 and is in contact with front wall 210, rear wall 240, and ceiling 250. Left side wall 220 is provided with a first opening 221 that communicates with hose 115 and a second opening 222 that communicates with hose 116. First opening 221 and second opening 222 are included in a supply section.

[0128] The first opening 221 is provided substantially vertically below the substantially vertical center of the structure 200A. The first opening 221 is an opening for supplying heated air from the air conditioner 11 to the inside I4. The first opening 221 is also an opening for supplying humidified air from the air conditioner 11 to the inside I4.

[0129] The second opening 222 is provided substantially vertically above the substantially vertical center of the structure 200A. The second opening 222 is an opening for supplying cooled air from the air conditioner 11 to the inside 14. The first opening 221 is an opening for supplying dehumidified air from the air conditioner 11 to the inside 14.

[0130] The first opening 221 and the second opening 222 may be provided in any one of 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 be provided in at least one of the front wall 210, the right wall 230, the rear wall 240, and the ceiling 250, in addition to the left wall 220. The first opening 221 and the second opening 222 may be provided forward of approximately the center of the structure 200A in the X direction. The first opening 221 and the second opening 222 may be provided in different walls.

[0131] The right side wall 230 faces the left side wall 220 and 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.

[0132] The opening 231 is an example of a discharge portion. The opening 231 is provided in the right side wall 230, which faces the left side wall 220 in which the first opening 221 and the second opening 222 are provided. The opening 231 is provided in approximately the center of the structure 200A in the approximately vertical direction.

[0133] The air in the inside I4 is discharged from the 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 in the inside I4 flows into the intake port of the air conditioner 11 via the opening 231 and the hose.

[0134] The opening 231 may be provided in any one of the front wall 210, the left wall 220, the rear wall 240, or the ceiling 250, instead of the right side wall 230. The opening 231 may also be provided in at least one of the front wall 210, the left side wall 220, the rear wall 240, or the ceiling 250, in addition to the right side wall 230. The opening 231 may be provided forward of approximately the center of the structure 200A in the X direction. The opening 231 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11.

[0135] The rear wall 240 faces the front wall 210 and is in contact with the left side wall 220, the right side wall 230, and the ceiling 250. The ceiling 250 faces the floor F and is in contact with the front wall 210, the left side wall 220, the right side wall 230, and the rear wall 240.

[0136] An inner side I4 is formed by surrounding the area of ​​floor F facing ceiling 250 with front wall 210, left side wall 220, right side wall 230, rear wall 240, and ceiling 250. Specifically, front wall 210 surrounds the front side of the area of ​​floor F where plants P are grown. Left side wall 220 surrounds the left side of the area of ​​floor F where plants P are grown. Right side wall 230 surrounds the right side of the area of ​​floor F where plants P are grown. Rear wall 240 surrounds the rear side of the area of ​​floor F where plants P are grown. Ceiling 250 surrounds the upper side of the area of ​​floor F where plants P are grown.

[0137] The inside I4 is isolated 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 inside I4, the outside of the structure 200A, and the passage 102 is covered by the front wall 210, the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250. It is difficult for people, equipment, and air to pass from the outside of the structure 200A and the passage 102 to the inside I4. Therefore, air supplied to the inside I4 through the first opening 221 and the second opening 222 is unlikely to flow from the inside I4 to the outside of the structure 200A. Air in the space I6 is also unlikely to flow to the inside I4. It is difficult for people or equipment to approach the inside I4. People or equipment cannot secure a working space.

[0138] Plants P are grown in the inner part I4. A part or all of the floor F in the inner part I4 is filled with soil (not shown) in which the plants P can be planted or with a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I4, the plants P are planted in soil or immersed in the nutrient solution.

[0139] Examples of configurations of the left side wall 220, the right side wall 230, the rear wall 240, the ceiling 250, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0140] The front wall 210 (14 slats SL), the left wall 220, the right wall 230, the rear wall 240, and the ceiling 250 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I6 is transmitted to the interior I4. Because the front wall 210 (14 slats SL), the left wall 220, the right wall 230, the rear wall 240, and the ceiling 250 are transparent or semi-transparent, the plants P on the interior I4 can be seen through from the outside of the structure 200A.

[0141] The depth of the structure 200A is a value that ensures D18 and D19. D18 is the shortest distance in the X direction from the plant P to the front wall 210 when the plant P has finished growing. D18 is preferably 1 to 10 centimeters, but is not limited to this. D19 is the shortest distance in the negative X direction from the plant P to the rear wall 240 when the plant P has finished growing. D19 is preferably 1 to 10 centimeters, but is not limited to this.

[0142] The height of the structure 200A is a value that ensures D20, which is the shortest distance in the Y direction from the plant P to the ceiling 250 when the plant P has finished growing. D20 is preferably, but not limited to, 1 to 10 centimeters.

[0143] The width of the structure 200A is a value that ensures D21 and D22. D21 is the shortest distance in the negative Z direction from the plant P to the left side wall 220 when the plant P has finished growing. D21 is preferably, but not limited to, 1 to 10 centimeters. 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, but not limited to, 1 to 10 centimeters.

[0144] The left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250 are components whose configuration cannot be changed. The front wall 210 is a component whose configuration can be changed. Therefore, the structure 200A is a variable structure. Note that at least one of the left side wall 220, the right side wall 230, the rear wall 240, and the ceiling 250 may be a component whose configuration can be changed. Various configurations of the structure 200A will be described below.

[0145] Figure 38 is a perspective view showing the detailed configuration of the structure 200A. The state shown in Figure 38 is one in which the slats SL have been slid in the Z direction from the states shown in Figures 32, 33, 34, 35, 36, and 37. Of the 14 slats SL, seven slats SL are housed in a case 213. The outside of the structure 200A, the passage 102, and the interior I4 are connected to each other through the front side of the structure 200A. By changing the state of the front wall 210, the outside of the structure 200A, the passage 102, and the interior I4 are now connected to each other. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 200A.

[0146] Figure 39 is a perspective view showing the detailed configuration of the structure 200A. The state of Figure 39 is an embodiment in which the slats SL have been slid in the Z direction from the state of Figure 38. The fourteen slats SL are housed in a case 213. The outside of the structure 200A and the passage 102 communicate with the inside I4 via the front side of the structure 200A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P via the front side of the structure 200A.

[0147] The state in Fig. 38 is also a state in which the slat SL has been slid in the minus Z direction from the state in Fig. 39. The states in Figs. 32, 33, 34, 35, 36, and 37 are also states in which the slat SL has been slid in the minus Z direction from the state in Fig. 38. By changing the state of the front wall 210, the state in which the outside of the structure 200A and the passage 102 are connected to the inside I4 is changed to a state in which the outside of the structure 200A and the passage 102 are connected to the inside I4.

[0148] (3) Operation The operation of the equipment 2 when a person or device performs harvesting work will be described. Since the operation of the structure 200A and the operation of the structure 200B are similar, the operation of the structure 200A will be mainly described. Figure 40 is a flowchart showing the operation of the equipment 2. Air heated by the air conditioner 11 is supplied to the inside I4 via the hose 115 and the first opening 221. The structure 200A has the same configuration as the structure 200A in Figures 32, 33, 34, 35, 36, and 37.

[0149] Fourteen slats SL cover the front side of the structure 200A, isolating the outside of the structure 200A and the passage 102 from the inside I4. The heated air supplied to the inside I4 does not easily flow to the outside of the structure 200A. The temperature of the inside I4 is maintained higher than the temperature of the space I6. Therefore, the inside I4 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting. No working space is provided.

[0150] A person or device moves from outside the greenhouse 10 into the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 200A. The person or device applies a force in the Z direction to one or more of the 14 slats SL. Because the slats SL are connected to adjacent slats SL, the force in the Z direction is transmitted to the 14 slats SL. Therefore, the 14 slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and slide in the Z direction (step S11).

[0151] As the slats SL slide in the Z direction, the rightmost slat SL of the 14 slats SL is stored in the case 213. When seven slats SL are stored in the case 213, the state of the structure 200A is changed to the state shown in Fig. 38 (step S12). A person or a device continues to apply a force in the Z direction to one or more slats SL.

[0152] As the slats SL slide in the Z direction, the 14 slats SL are stored in the case 213. The state of the structure 200A is changed to the state shown in FIG. 39 (step S13). The front side of the structure 200A connects the outside of the structure 200A and the passage 102 with the inside I4. Now that a working space has been secured, a person or a device can perform harvesting work on the plants P. The person or a device begins harvesting work on the plants P.

[0153] When the harvesting work is completed, a person or device applies a force in the negative Z direction to one or more slats SL stored in the case 213. Because the slats SL are connected to adjacent slats SL, the force in the negative Z direction is transmitted to the 14 slats SL. Therefore, the 14 slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and slide in the negative Z direction (step S14).

[0154] The slats SL are pulled out to the left of the case 213. When the seven slats SL are pulled out to the left from the case 213, the state of the structure 200A is changed to the state shown in Fig. 38 (step S15). A person or device continues to apply a force in the negative Z direction to one or more slats SL. The fourteen slats SL are guided by the third guide rail 211 and the fourth guide rail 212 and slid in the negative Z direction.

[0155] When the fourteen slats SL are pulled out to the left from the case 213, the structure 200A is changed to the structure 200A shown in Figures 32, 33, 34, 35, 36, and 37 (step S16). The front side of the structure 200A is covered by the fourteen slats SL. Therefore, the outside of the structure 200A and the passage 102 are blocked from the inside 14.

[0156] A person or device moves to the outside of the greenhouse 10 through the passage 102 and the entrance / exit 101. The person or device operates the air conditioner 11 to stop heating and start dehumidification. The supply of heated air to the inside I4 from the hose 115 and the first opening 221 is stopped. The air conditioner 11 supplies dehumidified air to the inside I4 through the hose 116 and the second opening 222. The humidity on the inside I4 decreases, and the humidity becomes lower than that on the outside of the structure 200A. As a result, the inside I4 becomes an environment suitable for seeding work.

Specifically, racks R are provided on the insides I4 and I5, and the products G are stored on the racks R. The racks R are the same as those in modification 1C, and therefore a description thereof will be omitted.

[0169] The depth and width of the structure 200A are the same as those of the modified example 2A, and therefore will not be described here. The height of the structure 200A is a value that ensures D34 (not shown). D34 is the shortest distance in the Y direction from the product G stored on the top platform 180 of the rack R to the ceiling 250. D34 is preferably 5 to 10 centimeters, but is not limited to this.

[0170] (4-5) Modification 2E The structure 200A and the structure 200B may be provided inside the livestock barn 60. Fig. 45 is a schematic diagram showing the overall configuration of the facility 2 according to modification 2E. Livestock L are raised in the insides I4 and I5.

[0171] The depth of the structure 200A is, but is not limited to, the depth of the livestock L plus 30 cm to 1 m. The width of the structure 200A is, but is not limited to, the sum of the widths of all the livestock L housed in the structure 200A plus 50 cm to 2 m. The height of the structure 200A is, but is not limited to, the height of the person performing livestock work plus 10 cm to 30 cm.

[0172] (4-6) Modification 2F The structure 200A and the structure 200B may be provided inside the land-based aquaculture farm 70.

[0174] (4-7) Modification 2G The front wall 210 of the second embodiment and modifications 2A, 2B, 2C, 2D, 2E, and 2F may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 211 and the fourth guide rail 212 by the control device.

[0175] (5) Features (5-1) The variable structure has a supply section including a first opening 221 provided approximately vertically below the center of the variable structure in the vertical direction, and a second opening 222 provided approximately vertically above the center of the variable structure in the vertical direction, the first opening 221 being an opening for supplying heated air from the air conditioner 11 to the inside I4 and the inside I5, and the second opening 222 being an opening for supplying cooled air from the air conditioner 11 to the inside I4 and the inside I5.

[0176] In order to create an environment suitable for plant cultivation, etc., a space where plants are grown may be heated and cooled. Heated air is lighter than unheated air. However, cooled air is heavier than uncooled air. Therefore, if heating and cooling are performed through the same opening, temperature unevenness may occur when at least one of heating and cooling is performed.

[0177] The variable structure is provided with a first opening 221 that supplies heated air to the insides I4 and I5, and a second opening 222 that supplies cooled air to the insides I4 and I5. Therefore, the variable structure makes it difficult for temperature unevenness to occur on the insides I4 and I5 in the case of heating and cooling. Therefore, the variable structure makes the insides I4 and I5 an environment more suitable for growing plants P, etc.

[0178] (5-2) The variable structure has a supply section including a first opening 221 provided approximately vertically below the center of the variable structure in the vertical direction, and a second opening 222 provided approximately vertically above the center of the variable structure in the vertical direction, the first opening 221 being an opening for supplying humidified air from the air conditioner 11 to the inside I4 and the inside I5, and the second opening 222 being an opening for supplying dehumidified air from the air conditioner 11 to the inside I4 and the inside I5.

[0179] To create an environment suitable for plant cultivation, etc., a space where plants are cultivated may be humidified and dehumidified. Humidified air is lighter than non-humidified air. However, dehumidified air is heavier than non-dehumidified air. Therefore, if humidification and dehumidification are performed through the same opening, humidity unevenness may occur when at least one of humidification and dehumidification is performed.

[0180] The variable structure is provided with a first opening 221 that supplies humidified air to the insides I4 and I5, and a second opening 222 that supplies dehumidified air to the insides I4 and I5. Therefore, the variable structure makes it difficult for humidity unevenness to occur on the insides I4 and I5 when humidifying and dehumidifying. Therefore, the variable structure makes the insides I4 and I5 an environment more suitable for growing plants P, etc.

[0181] <Third Embodiment> (1) Overall Configuration The overall configuration of the facility 3 according to the third embodiment will be described. Hereinafter, similarities between the second and third embodiments will be omitted, and differences between the second and third embodiments will be mainly described. Figure 47 is a schematic diagram showing the overall configuration of the facility 3 according to the third embodiment. The facility 3 mainly includes a greenhouse 10 and an air conditioner 11.

[0182] (1-1) Greenhouse The greenhouse 10 is mainly equipped with a structure 300A and a structure 300B. The interior of the greenhouse 10 is divided into an inside I7 of the structure 300A, an inside I8 of the structure 300B, and a space I9. The space I9 is ​​outside the structures 300A and 300B and is inside the greenhouse 10. Details of the structures 300A and 300B will be described later.

[0184] (2) Detailed Configuration The detailed configuration of the structure 300A and the structure 300B will be described. The structure 300A is a variable structure whose configuration can be changed by the operation of the structure 300A. The structure 300B is a variable structure whose configuration can be changed by the operation of the structure 300B. The structures of the structure 300A and the structure 300B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 300A is similar to the function of the structure 300B. The structure and function of the structure 300A will be described below.

[0185] Fig. 48 is a perspective view showing the detailed configuration of structure 300A. Fig. 49 is a front view showing the detailed configuration of structure 300A. Fig. 50 is a rear view showing the detailed configuration of structure 300A. Fig. 51 is a left side view showing the detailed configuration of structure 300A. Fig. 52 is a right side view showing the detailed configuration of structure 300A. Fig. 53 is a plan view showing the detailed configuration of structure 300A.

[0186] The structure 300A mainly has a front wall 310 , a third guide rail 311 , a fourth guide rail 312 , a left wall 320 , a right wall 330 , a rear wall 340 , and a ceiling 350 .

[0187] The third guide rail 311 includes two rows of rails aligned in the X direction and extending in the Z direction. The front rail of the two rows of rails is referred to as the "third front rail." The rear rail of the two rows of rails is referred to as the "third rear rail."

[0188] The fourth guide rail 312 faces the third guide rail 311 and includes two rows of rails aligned in the X direction and extending in the Z direction. The front rail of the two rows of rails is referred to as the "fourth front rail." The rear rail of the two rows of rails 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.

[0189] The front wall 310 is mainly composed of two slats SL. The two slats SL are approximately perpendicular to the floor F. The two slats SL are guided by the third guide rail 311 and the fourth guide rail 312 and can slide in the Z direction or the negative Z direction (the direction in which the third guide rail 311 and the fourth guide rail 312 extend). The configuration of the front wall 310 can be changed by the two slats SL sliding while being guided by the third guide rail 311 and the fourth guide rail 312.

[0190] Of the two slats SL that make up the front wall 310, the left slat SL will be referred to as the "left slat SL" and the right slat SL will be referred to as the "right slat SL." The left slat SL can move left and right by sliding it between the third front rail and the fourth front rail. The right slat SL can move left and right by sliding it 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 when moving left and right.

[0191] The front wall 310 is an example of a first component and faces the aisle 102. The left side wall 320 faces the right side wall 330 and is in contact with the front wall 310, the rear wall 340, and the ceiling 350. The right side wall 330 faces the left side wall 320 and is in contact with the front wall 310, the rear wall 340, and the ceiling 350.

[0192] Rear wall 340 faces front wall 310 and is in contact with left side wall 320, right side wall 330, and ceiling 350. Rear wall 340 is provided with opening 341 that communicates with a hose. Rear wall 340 also is provided with opening 342 that communicates with the outside of structure 300A.

[0193] The opening 341 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the inside 17 through the opening 341. The opening 341 is provided approximately vertically below the approximate vertical center of the structure 300A.

[0194] The opening 341 may be provided in any of the front wall 310, the left side wall 320, the right side wall 330, or the ceiling 350, instead of the rear wall 340. The opening 341 may be provided in any of the front wall 310, the left side wall 320, the right side wall 330, or the ceiling 350, in addition to the rear wall 340. The opening 341 may be provided approximately vertically above the approximately vertical center of the rear wall 340. The opening 341 may be provided to the right of the approximately Z-direction center of the structure 300A.

[0195] The opening 342 is an example of a discharge portion. The opening 342 is provided substantially vertically above the substantially vertical center of the structure 300A.

[0196] The air inside I7 is discharged from inside I7 to the outside of the structure 300A through the opening 342. For example, the opening 342 is connected to a hose (not shown) that is connected to the intake port of the air conditioner 11. The air inside I7 flows into the intake port of the air conditioner 11 via the opening 342 and the hose.

[0197] The opening 342 may be provided in any one of the front wall 310, the left side wall 320, the right side wall 330, or the ceiling 350, instead of the rear wall 340. The opening 342 may be provided in at least one of the front wall 310, the left side wall 320, the right side wall 330, and the ceiling 350, in addition to the rear wall 340. The opening 342 may be provided approximately vertically below the approximately vertical center of the rear wall 340. The opening 342 may be provided to the left of the approximately Z-direction center of the structure 300A. The opening 342 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11.

[0198] The ceiling 350 faces the floor F and is in contact with the front wall 310 , the left side wall 320 , the right side wall 330 , and the rear wall 340 .

[0199] An inside I7 is formed by surrounding the area of ​​floor F facing ceiling 350 with front wall 310, left wall 320, right wall 330, rear wall 340, and ceiling 350. Specifically, front wall 310 surrounds the front side of the area of ​​floor F where plants P are grown. Left wall 320 surrounds the left side of the area of ​​floor F where plants P are grown. Right wall 330 surrounds the right side of the area of ​​floor F where plants P are grown. Rear wall 340 surrounds the rear side of the area of ​​floor F where plants P are grown. Ceiling 350 surrounds the upper side of the area of ​​floor F where plants P are grown.

[0200] The inside I7 is isolated from the outside of the structure 300A and the passage 102 by the front wall 310, left side wall 320, right side wall 330, rear wall 340, and ceiling 350. The front wall 310, left side wall 320, right side wall 330, rear wall 340, and ceiling 350 provide a barrier between the inside I7 and the outside of the structure 300A and the passage 102. It is difficult for people, equipment, and air to pass from the outside of the structure 300A and the passage 102 to the inside I7. Therefore, air supplied to the inside I7 through the opening 341 is unlikely to flow from the inside I7 to the outside of the structure 300A. Air in space I9 is ​​also unlikely to flow to the inside I7. It is difficult for people or equipment to access the inside I7. People or equipment cannot secure a working space.

[0201] Plants P are grown in the inner part I7. A part of the bed F in the inner part I7 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I7, the plants P are planted in soil or immersed in the nutrient solution.

[0202] Examples of configurations of the left side wall 320, the right side wall 330, the rear wall 340, the ceiling 350, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0203] The front wall 310 (two slats SL), the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I9 is ​​transmitted to the interior I7. Because the front wall 310 (two slats SL), the left wall 320, the right wall 330, the rear wall 340, and the ceiling 350 are transparent or semi-transparent, the plants P on the interior I7 can be seen through from the outside of the structure 300A.

[0204] The depth of the structure 300A is a value that ensures D35 and D36. D35 is the shortest distance in the X direction from the plant P to the front wall 310 when the plant P has finished growing. D35 is preferably 1 to 10 centimeters, but is not limited to this. D36 is the shortest distance in the negative X direction from the plant P to the rear wall 340 when the plant P has finished growing. D36 is preferably 1 to 10 centimeters, but is not limited to this.

[0205] The height of the structure 300A is a value that ensures D37. D37 is the shortest distance in the Y direction from the plant P to the ceiling 350 when the plant P has finished growing. D37 is preferably, but not limited to, 1 to 10 centimeters.

[0206] The width of the structure 300A is a value that ensures D38 and D39. D38 is the shortest distance in the negative Z direction from the plant P to the left side wall 320 when the plant P has finished growing. D38 is preferably, but not limited to, 1 to 10 centimeters. D39 is the shortest distance in the Z direction from the plant P to the right side wall 330 when the plant P has finished growing. D39 is preferably, but not limited to, 1 to 10 centimeters.

[0207] The left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350 are components whose configuration cannot be changed. The front wall 310 is a component whose configuration can be changed. Therefore, the structure 300A is a variable structure. Note that at least one of the left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350 may be a component whose configuration can be changed. Various configurations of the structure 300A will be described below.

[0208] Figure 54 is a perspective view showing the detailed configuration of the structure 300A. In the state shown in Figure 54, the left slat SL has been slid in the Z direction from the states shown in Figures 48, 49, 50, 51, 52, and 53. Because the left slat SL has been slid in the Z direction, it is generally aligned with the right slat SL in the X direction. The interior I7 is now connected to the outside of the structure 300A and the passage 102 through the left front side of the structure 300A. By changing the state of the front wall 310, the state where the outside of the structure 300A, the passage 102, and the interior I7 were blocked off has been changed to a state where the outside of the structure 300A, the passage 102, and the interior I7 are now connected. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 300A.

[0209] Figure 55 is a perspective view showing the detailed configuration of the structure 300A. In the state shown in Figure 55, the right slat SL has been slid in the negative Z direction from the states shown in Figures 48, 49, 50, 51, 52, and 53. Because the right slat SL has been slid in the negative Z direction, it is generally aligned with the left slat SL in the X direction. The interior I7 is now connected to the outside of the structure 300A and the passage 102 through the right front side of the structure 300A. By changing the state of the front wall 310, the state where the outside of the structure 300A, the passage 102, and the interior I7 were blocked has been changed to a state where the outside of the structure 300A, the passage 102, and the interior I7 are now connected to the inside I7. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 300A.

[0210] 48, 49, 50, 51, 52, and 53 are also modes in which the left slat SL has been slid in the minus Z direction from the mode in Fig. 54. By changing the mode of the front wall 310, the state in which the outside of the structure 300A and the passage 102 are connected to the inside I7 is changed to a state in which the outside of the structure 300A and the passage 102 are blocked from the inside I7.

[0211] 48, 49, 50, 51, 52, and 53 are also modes in which the right slat SL has been slid in the Z direction from the mode of Fig. 55. By changing the mode of the front wall 310, the state in which the outside of the structure 300A and the passage 102 are connected to the inside I7 is changed to a state in which the outside of the structure 300A and the passage 102 are blocked from the inside I7.

[0212] (3) Operation The operation of the equipment 3 when a person or device performs harvesting work will be described. Since the operation of the structure 300A and the operation of the structure 300B are similar, the operation of the structure 300A will be mainly described. Figure 56 is a flowchart showing the operation of the equipment 3. Air heated by the air conditioner 11 is supplied to the inside I7 through the hose and the opening 341. The structure 300A has the same configuration as the structure 300A shown in Figures 48, 49, 50, 51, 52, and 53.

[0213] Two slats SL cover the front side of the structure 300A, blocking the outside of the structure 300A and the passage 102 from the inside I7. The heated air supplied to the inside I7 does not easily flow to the outside of the structure 300A. The temperature of the inside I7 is maintained higher than the temperature of the space I9. Therefore, the inside I7 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting.

[0214] A person or device moves from outside the greenhouse 10 into the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 300A. The person or device applies a force in the Z direction to the left slat SL of the two slats SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the Z direction. The left slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the Z direction (step S21).

[0215] Because the left slat SL has been slid in the Z direction, the left slat SL is generally aligned with the right slat SL in the X direction. The structure 300A is changed to the state shown in Figure 54 (step S22). The left front side of the structure 300A connects the outside of the structure 300A and the passage 102 with the inside I7. Now that a working space has been secured, a person or device can harvest the plants P on the left side. The person or device begins harvesting the plants P on the left side.

[0216] When the harvesting work on the plants P on the left side is completed, a person or device applies a force in the minus Z direction to the left slat SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the minus Z direction. The left slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the minus Z direction (step S23).

[0217] Because the left slat SL has been slid in the minus Z direction, the state of the structure 300A is changed to the state of the structure 300A shown in Figures 48, 49, 50, 51, 52, and 53 (step S24). Because the left front side of the structure 300A is covered by the left slat SL, the outside of the structure 300A and the passage 102 are blocked from the inside 17.

[0218] A person or device applies a force in the negative Z direction to the right slat SL of the two slats SL. Because the right slat SL and the left slat SL are independent, only the right slat SL receives the force in the negative Z direction. The right slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the negative Z direction (step S25).

[0219] Because the right slat SL has been slid in the negative Z direction, the right slat SL is generally aligned with the left slat SL in the X direction. The structure 300A is changed to the state shown in FIG. 55 (step S26). The right front side of the structure 300A connects the outside of the structure 300A and the passage 102 with the inside I7. Now that a working space has been secured, a person or device can harvest the plants P on the right side. The person or device begins harvesting the plants P on the right side.

[0220] When the harvesting work on the right-side plants P is completed, a person or device applies a force in the Z direction to the right slat SL. Because the right slat SL and the left slat SL are independent, only the right slat SL receives the force in the Z direction. The right slat SL is guided by the third guide rail 311 and the fourth guide rail 312 and slides in the Z direction (step S27).

[0221] Because the right slat SL has been slid in the Z direction, the state of the structure 300A is changed to the state shown in Figures 48, 49, 50, 51, 52, and 53 (step S28). Because the right front side of the structure 300A is covered by the right slat SL, the outside of the structure 300A and the passage 102 are blocked from the inside 17.

[0246] The structure 400A mainly has a front wall 410, a left side wall 420, a right side wall 430, a rear wall 440, a ceiling 450, and a rotation axis AX.

[0247] The front wall 410 is an example of a first component and faces the aisle 102. The upper end of the front wall 410 is connected to the front end of the ceiling 450.

[0248] The left side wall 420 faces the right side wall 430 and is in contact with the front wall 410, the rear wall 440, and the ceiling 450. An opening 421 that communicates with the hose 111 is provided in the left side wall 420.

[0249] The opening 421 is an example of a supply section. Air conditioned by the air conditioner 11 is supplied to the inside I10 through the opening 421. The opening 421 is provided approximately vertically below the approximate vertical center of the structure 400A.

[0250] 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 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 substantially vertically above the substantially vertical center of the structure 400A. The opening 421 may be provided forward of the substantially X-direction center of the structure 400A.

[0251] The right side wall 430 faces the left side wall 420 and 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.

[0252] The opening 431 is an example of a discharge portion. The opening 431 is provided substantially vertically above the substantially vertical center of the structure 400A.

[0253] 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 into the intake port of the air conditioner 11 via the opening 431 and the hose.

[0254] The opening 431 may be provided in any of the front wall 410, the left wall 420, the rear wall 440, or the ceiling 450 instead of the right side wall 430. The opening 431 may be provided in at least one of the front wall 410, the left side wall 420, the rear wall 440, or the ceiling 450, in addition to the right side wall 430. The opening 431 may be provided substantially vertically below the substantially vertical center of the structure 400A. The opening 431 may be provided rearward of the substantially X-direction center of the structure 400A. The opening 431 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air intake of the air conditioner 11.

[0255] The rear wall 440 faces the front wall 410 and is in contact with the left side wall 420, the right side wall 430, and the ceiling 450. A rotating member 441 and a fixed member 442 are provided on the rear wall 440.

[0256] The rotating member 441 is a member for fixing the ceiling 450 in a rotated state. The rotating member 441 is provided at approximately the center of the rear wall 440 in the Z direction, and is provided on the front side of the rear wall 440. The rotating member 441 is provided rotatable on a plane extending in the Y direction and the Z direction, with the rotation center being approximately the center of the rotating member 441 in the Y direction and approximately the center of the rotating member 441 in the Z direction. Note that multiple rotating members 441 may be provided on the rear wall 440.

[0257] The fixing member 442 is a member for fixing the ceiling 450 in a rotated state. The fixing member 442 is provided at approximately the center of the rear wall 440 in the approximately horizontal direction, on the rear side of the rear wall 440. The fixing member 442 is fixed to the rear wall 440. The fixing member 442 is provided so as to face the rotating member 441. Note that a plurality of fixing members 442 may be provided on the rear wall 440. The rotation axis AX is provided along the rear end portion of the ceiling 450.

[0258] The ceiling 450 faces the floor F and is in contact with the front wall 410, the left side wall 420, the right side wall 430, and the rear wall 440. The ceiling 450 can be moved by rotating about a rotation axis AX. The ceiling 450 is provided so as to be rotatable on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. The front end of the ceiling 450 is connected to the upper end of the front wall 410. Therefore, when the ceiling 450 is rotated about the rotation axis AX, the front wall 410 also rotates along with the ceiling 450. This allows the configuration of the front wall 410 to be changed.

[0259] The area of ​​floor F facing the ceiling 450 is surrounded by a front wall 410, a left wall 420, a right wall 430, a rear wall 440, and the ceiling 450, thereby forming an inside I10. Specifically, the front wall 410 surrounds the front side of the area of ​​floor F where plants P are grown. The left wall 420 surrounds the left side of the area of ​​floor F where plants P are grown. The right wall 430 surrounds the right side of the area of ​​floor F where plants P are grown. The rear wall 440 surrounds the rear side of the area of ​​floor F where plants P are grown. The ceiling 450 surrounds the upper side of the area of ​​floor F where plants P are grown.

[0260] The inside I10 is isolated from the outside of the structure 400A and the passage 102 by the front wall 410, left side wall 420, right side wall 430, rear wall 440, and ceiling 450. The space between the inside I10, the outside of the structure 400A, and the passage 102 is covered by the front wall 410, left side wall 420, right side wall 430, rear wall 440, and ceiling 450. It is difficult for people, equipment, and air to pass from the outside of the structure 400A and the passage 102 to the inside I10. Therefore, air supplied to the inside I10 through the opening 421 is unlikely to flow from the inside I10 to the outside of the structure 400A. Air in the space I14 is also unlikely to flow to the inside I10. It is difficult for people or equipment to approach the inside I10. People or equipment cannot secure a working space.

[0261] Plants P are grown in the inner part I10. A part of the floor F in the inner part I10 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I10, the plants P are planted in soil or immersed in the nutrient solution.

[0262] Examples of configurations of the front wall 410, left side wall 420, right side wall 430, rear wall 440, and ceiling 450 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0263] The front wall 410, the left wall 420, the right wall 430, the rear wall 440, and the ceiling 450 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I14 is transmitted to the 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 semi-transparent, the plants P on the interior I10 can be seen through from the outside of the structure 400A.

[0264] The depth of the structure 400A is a value that ensures D52 and D53. D52 is the shortest distance in the X direction from the plant P to the front wall 410 when the plant P has finished growing. D52 is preferably, but not limited to, 1 to 10 centimeters. D53 is the shortest distance in the negative X direction from the plant P to the rear wall 440 when the plant P has finished growing. D53 is preferably, but not limited to, 1 to 10 centimeters.

[0265] The height of the structure 400A is a value that ensures D54, which is the shortest distance in the Y direction from the plant P to the ceiling 450 when the plant P has finished growing. D54 is preferably, but not limited to, 1 to 10 centimeters.

[0266] The width of the structure 400A is a value that ensures D55 and D56. D55 is the shortest distance in the negative Z direction from the plant P to the left side wall 420 when the plant P has finished growing. D55 is preferably, but not limited to, 1 to 10 centimeters. D56 is the shortest distance in the Z direction from the plant P to the right side wall 430 when the plant P has finished growing. D56 is preferably, but not limited to, 1 to 10 centimeters.

[0267] The left side wall 420, the right side 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, the structure 400A is a variable structure. Note that at least one of the left side wall 420, the right side wall 430, and the rear wall 440 may be components whose configuration can be changed. For example, at least one of the left side wall 420 and the right side wall 430 may be connected to the ceiling 450. In this case, at least one of the left side wall 420 and the right side wall 430 connected to the ceiling 450 rotates along with the ceiling 450. Below, configurations of the structure 400A that differ from the configurations of the structure 400A in Figures 64, 65, 66, 67, 68, and 69 will be described.

[0268] Fig. 70 is a perspective view showing the detailed configuration of the structure 400A. Fig. 71 is a front view showing the detailed configuration of the structure 400A. Fig. 72 is a rear view showing the detailed configuration of the structure 400A. Fig. 73 is a left side view showing the detailed configuration of the structure 400A. Fig. 74 is a right side view showing the detailed configuration of the structure 400A. Fig. 75 is a plan view showing the detailed configuration of the structure 400A.

[0269] The aspects of the structure 400A in Figures 70, 71, 72, 73, 74, and 75 are aspects in which the ceiling 450 has been rotated about the rotation axis AX from the aspects of the structure 400A in Figures 64, 65, 66, 67, 68, and 69. The ceiling 450 has been rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. As the ceiling 450 has been rotated, the front wall 410 has also been rotated along with the ceiling 450.

[0270] The rotating member 441 is rotated by slightly less than 90 degrees on a plane extending in the Y and Z directions, with the center of rotation being approximately the center of the rotating member 441 in the Y direction and the center of the Z direction. The ceiling 450 is sandwiched and fixed between the rotating member 441 on the front side of the ceiling 450 and the fixed member 442 on the rear side of the ceiling 450. As a result, the ceiling 450 and the front wall 410 are fixed in a state rotated about the rotation axis AX.

[0271] The inside I10 of the structure 400A is in a state of communication with the outside of the structure 400A and the passage 102 via the front and upper sides. By changing the configuration of the ceiling 450 and the front wall 410, the state in which the outside of the structure 400A and the passage 102 were isolated from the inside I10 has been changed to a state in which the outside of the structure 400A and the passage 102 are in communication with the inside I10. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P via the front and upper sides of the structure 400A.

[0272] 64, 65, 66, 67, 68, and 69 are also forms in which the ceiling 450 is rotated about the rotation axis AX from the forms of the structure 400A in Figures 70, 71, 72, 73, 74, and 75. The ceiling 450 is rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. Because the ceiling 450 is rotated, the front wall 410 is also rotated along with the ceiling 450.

[0273] By changing the configuration of the ceiling 450 and the front wall 410, the state in which the outside of the structure 400A and the passage 102 are connected to the inside I10 has been changed to a state in which the outside of the structure 400A and the passage 102 are blocked from the inside I10.

[0274] (3) Operation The operation of the equipment 4 when a person or device performs harvesting work will be described. Since the operation of the structure 400A, the operation of the structure 400B, the operation of the structure 400C, and the operation of the structure 400D are similar, the operation of the structure 400A will be mainly described. Figure 76 is a flowchart showing the operation of the equipment 4. Air heated by the air conditioner 11 is supplied to the inside I10 through the hose and the opening 421. The structure 400A is the same as the structure 400A shown in Figures 64, 65, 66, 67, 68, and 69.

[0275] A front wall 410 covers the front side of the structure 400A, and a ceiling 450 covers the upper side of the structure 400A. Therefore, the outside of the structure 400A and the passage 102 are 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 of the inside I10 is maintained higher than the temperature of the space I14. Therefore, the inside I10 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting.

[0276] A person or device moves from the outside of the greenhouse 10 into the inside of the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 400A. The person or device applies a force in the Y direction and the minus X direction to at least one of the front wall 410 and the ceiling 450. The ceiling 450 receives the forces in the Y direction and the minus X direction and is rotated about the rotation axis AX. Specifically, the ceiling 450 rotates in a plane extending in the X direction and the Y direction with the rotation axis AX as the rotation center. Furthermore, the front wall 410 connected to the ceiling 450 also rotates together with the ceiling 450 (step S31).

[0277] As the ceiling 450 continues to rotate, it collides with the fixed member 442. When the ceiling 450 collides with the fixed member 442, it receives a force in the X direction from the fixed member 442. This stops the rotation of the front wall 410 and the ceiling 450 (step S32). The ceiling 450 has rotated slightly less than 90 degrees on a plane extending in the X and Y directions, with the rotation axis AX as the center of rotation.

[0278] A person or device rotates the rotating member 441. The rotating member 441 is rotated slightly less than 90 degrees on a plane extending in the Y and Z directions, with the center of rotation being approximately the center of the rotating member 441 in the Y direction and approximately the center of the rotating member 441 in the Z direction. The ceiling 450 is fixed by being sandwiched between the rotating member 441 on the front side of the ceiling 450 and the fixed member 442 on the rear side of the ceiling 450. The front wall 410 and the ceiling 450 are fixed in a state rotated about the rotation axis AX. The configuration of the structure 400A can be changed to the configurations shown in Figures 70, 71, 72, 73, 74, and 75 (step S33).

[0279] The front and top sides of the structure 400A allow the outside of the structure 400A and the passage 102 to communicate with the inside 110. Now that the work space has been secured, a person or device can begin harvesting the plants P. The person or device begins harvesting the plants P.

[0280] When the harvesting operation is completed, a person or a device rotates the rotating member 441. The rotating member 441 rotates slightly less than 90 degrees on a plane extending in the Y and Z directions, with the center of rotation being approximately the center of the rotating member 441 in the Y direction and the center of the Z direction. The ceiling 450 is released from being sandwiched between the rotating member 441 and the fixed member 442. The ceiling 450 receives a force in the negative Y direction due to gravity. Therefore, the ceiling 450 rotates around the rotation axis AX. Specifically, the ceiling 450 rotates on a plane extending in the X and Y directions with the rotation axis AX as the center of rotation. The front wall 410 connected to the ceiling 450 also rotates along with the ceiling 450 (step S34). The person or device may apply a force in the negative Y direction and the X direction to at least one of the front wall 410 and the ceiling 450.

[0281] As the front wall 410 and the ceiling 450 continue to rotate, the front wall 410 collides with the floor F. The front wall 410 that has collided with the floor F receives a force in the Y direction from the floor F. This stops the rotation of the front wall 410 and the ceiling 450. The ceiling 450 has rotated slightly less than 90 degrees on a plane extending in the X and Y directions, with the rotation axis AX as the center of rotation.

[0282] The ceiling 450 covers the upper side of the structure 400A. The front wall 410 covers the front side of the structure 400A. The structure 400A is changed to the configuration shown in Figures 64, 65, 66, 67, 68, and 69 (step S35). The outside and passage 102 of the structure 400A are isolated from the inside I10.

[0302] <Fifth Embodiment> (1) Overall Configuration The overall configuration of the facility 5 according to the fifth embodiment will be described. Hereinafter, similarities between the first and fifth embodiments will be omitted, and differences between the first and fifth embodiments will be mainly described. Fig. 83 is a schematic diagram showing the overall configuration of the facility 5. The facility 5 mainly includes a greenhouse 10 and an air conditioner 11.

[0303] The interior of the greenhouse 10 is mainly provided with a structure 500A and a structure 500B. The interior of the greenhouse 10 is divided into an inside I15 of the structure 500A, an inside I16 of the structure 500B, and a space I17. The space I17 is outside the structures 500A and 500B and is inside the greenhouse 10. Details of the structures 500A and 500B will be described later.

[0304] The air conditioner 11 conditions the inside I15 and the inside I16. The air outlet of the air conditioner 11 is connected to the inside I15 by a hose 111 (an example of a first hose). The air outlet of the air conditioner 11 is also connected to the inside I16 by a hose (an example of a first hose, not shown) different from the hose 111. Air conditioned by the air conditioner 11 is supplied to the inside I15 and the inside I16 via the hose 111 or the like.

[0305] (2) Detailed Configuration The detailed configuration of the structure 500A and the structure 500B will be described. The structure 500A is a variable structure that can change the state of the structure 500A by operating the structure 500A. The structure 500B is a variable structure that can change the state of the structure 500B by operating the structure 500B. The structures of the structure 500A and the structure 500B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 500A and the structure 500B are similar. The structure and function of the structure 500A will be described below. Figure 84 is a perspective view showing the detailed configuration of the structure 500A.

[0306] The structure 500A mainly has 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, a ceiling 150, and a bottom plate 560. The front wall 110, the first guide rail 112, the second guide rail 113, the case 114, the left side wall 120, the right side wall 130, the rear wall 140, and the ceiling 150 are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0307] The bottom plate 560 faces the ceiling 150 and is in contact with the front wall 110, the rear wall 140, the left side wall 120, and the right side wall 130. The bottom plate 560 is placed on the ground or on the floor of another structure (such as the greenhouse 10 or another adjustable structure). At least one of the openings 121 and 131 may be provided in the bottom plate 560.

[0308] An interior I15 is formed by surrounding the area where the plant P is grown with a front wall 110, a left side wall 120, a right side wall 130, a rear wall 140, a ceiling 150, and a bottom plate 560. Specifically, the front side of the area where the plant P is grown is surrounded by the front wall 110. The left side of the area where the plant P is grown is surrounded by the left side. The right side of the area where the plant P is grown is surrounded by the right side. The rear wall 140 surrounds the rear side of the area where the plant P is grown. The ceiling 150 surrounds the upper side of the area where the plant P is grown. The bottom plate 560 surrounds the lower side of the area where the plant P is grown.

[0309] The inside I15 is isolated from the outside of the structure 500A and the passage 102 by the front wall 110, left side wall 120, right side wall 130, rear wall 140, ceiling 150, and bottom plate 560. The space between the inside I15, the outside of the structure 500A, and the passage 102 is covered by the front wall 110, left side wall 120, right side wall 130, rear wall 140, ceiling 150, and bottom plate 560. It is difficult for people, equipment, and air to pass from the outside of the structure 500A and the passage 102 to the inside I15. Therefore, air supplied to the inside I1 through the opening 121 is unlikely to flow from the inside I15 to the outside of the structure 500A. Air in space I17 is also unlikely to flow to the inside I15. It is difficult for people or equipment to approach the inside I15. People or equipment cannot secure a working space.

[0310] Plants P are grown in the inner side I15. A bottom plate 560 covering a part or the entire area of ​​the inner side I15 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I15, the plants P are planted in soil or immersed in the nutrient solution.

[0311] The depth of the structure 500A is a value that ensures D72 and D73. D72 is the shortest distance in the X direction from the plant P to the front wall 110 when the plant P has finished growing. D72 is preferably 1 to 10 centimeters, but is not limited to this. D73 is the shortest distance in the negative X direction from the plant P to the rear wall 140 when the plant P has finished growing. D73 is preferably 1 to 10 centimeters, but is not limited to this.

[0312] The height of the structure 500A is a value that ensures D74. D74 is the shortest distance in the Y direction from the plant P to the ceiling 150 when the plant P has finished growing. D74 is preferably, but is not limited to, 1 to 10 centimeters.

[0313] The width of the structure 500A is a value that ensures D75 and D76. D75 is the shortest distance in the negative Z direction from the plant P to the left side wall 120 when the plant P has finished growing. D75 is preferably, but not limited to, 1 to 10 centimeters. D76 is the shortest distance in the Z direction from the plant P to the right side wall 130 when the plant P has finished growing. D76 is preferably, but not limited to, 1 to 10 centimeters.

[0314] The bottom plate 560 is a component that cannot be changed in shape. The front wall 110 is a component that can be changed in shape. Therefore, the structure 500A is a variable structure. Note that the bottom plate 560 may also be a component that can be changed in shape. Various aspects of the structure 500A will be described below.

[0315] Figure 85 is a perspective view showing the detailed configuration of the structure 500A. The state of Figure 85 is an embodiment in which the slats SL are slid in the Y direction from the state of Figure 84. The nine slats SL are housed in a case 114. The outside of the structure 500A and the passage 102 communicate with the inside I15 via the front side of the structure 500A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P via the front side of the structure 500A.

[0316] 84 is also an embodiment in which the slat SL has been slid in the minus Y direction from the embodiment in Fig. 85. By changing the embodiment of the front wall 110, the state in which the outside of the structure 500A and the passage 102 are connected to the inside I15 is changed to a state in which the outside of the structure 500A and the passage 102 are blocked from the inside I15.

[0317] (3) Modifications The following description of modifications of the fifth embodiment will focus on the differences from the first embodiment, omitting the description of the similarities to the fifth embodiment.

[0318] (3-1) Variant 5A The structure 500A and the structure 500B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0319] (3-2) Modification 5B The front wall 110 of the fifth embodiment and modification 5A may be modified by a control device (not shown). In other words, the slat SL may slide on the first guide rail 112 and the second guide rail 113 by the control device.

[0320] (4) Features (4-1) The variable structure is installed inside another structure. In the inside I15 and the inside I16, plants P or mushrooms M are cultivated, livestock L are raised, aquatic organisms Q are farmed, merchandise G is stored, or a server SV is installed. The variable structure includes a front wall 110, a ceiling 150, a rear wall 140, a left side wall 120, a right side wall 130, and a bottom plate 560. The front wall 110 can be changed and erected inside. The ceiling 150 is in contact with the front wall 110. The rear wall 140 is erected inside, faces the front wall 110, and is in contact with the ceiling 150. The left side wall 120 is erected inside and is in contact with the front wall 110, the ceiling 150, and the rear wall 140. The right side wall 130 stands inside, faces the left side wall 120, and is in contact with the front wall 110, the ceiling 150, and the rear wall 140. The bottom plate 560 faces the ceiling 150 and is in contact with the front wall 110. The insides I15 and I16 are formed by the front wall 110, the ceiling 150, the rear wall 140, the left side wall 120, the right side wall 130, and the bottom plate 560 surrounding them. A supply port is an opening that supplies conditioned air from the air conditioner 11 on the outside to the insides I15 and I16 and is connected to a first hose that communicates with the air conditioner 11, and is provided in at least one of the front wall 110, the ceiling 150, the rear wall 140, the left side wall 120, the right side wall 130, and the bottom plate 560. By changing the configuration of the front wall 110, the state in which the outside of the variable structure is isolated from the insides I15 and I16 can be changed to a state in which the outside is communicated with the insides I15 and I16.

[0321] Therefore, the variable structure can achieve energy savings in the cultivation of plants P and reduce costs associated with the cultivation of plants P. The variable structure allows people or equipment to work on plants P on the insides I15 and I16. The variable structure can protect plants P from physical external forces.

[0322] The bottom plate 560 encloses the inner side 115 and the inner side 116. The variable structure can also suppress heat loss to the lower side. Therefore, the variable structure can achieve energy savings in the cultivation of the plants P, and can reduce the costs associated with the cultivation of the plants P.

[0323] The variable structure can form the insides I15 and I16 using only the components of the variable structure. Therefore, the variable structure can be moved to another location while still in a state in which plants P are being cultivated.

[0324] (4-2) The variable structure has exhaust ports for discharging air from the inside I15 and the inside I16 to the outside, provided in at least one of the front wall 110, the ceiling 150, the rear wall 140, the left side wall 120, the right side wall 130, and the bottom plate 560.

[0325] Therefore, the variable structure can stably maintain the air pressure and airflow in the inside 115 and the inside 116. Also, the variable structure can maintain its airtightness for a longer period of time.

[0326] (4-3) The exhaust port of the variable structure is connected to a second hose that is connected to the air conditioner 11. Therefore, the variable structure can achieve energy savings in cultivating the plants P, and can reduce the costs associated with cultivating the plants P.

[0327] <Sixth Embodiment> (1) Overall Configuration The overall configuration of the facility 6 according to the sixth embodiment will be described. Hereinafter, similarities between the fifth and sixth embodiments will be omitted, and differences between the fifth and sixth embodiments will be mainly described. Fig. 86 is a schematic diagram showing the overall configuration of the facility 6 according to the sixth embodiment. The facility 6 mainly includes a greenhouse 10 and an air conditioner 11.

[0328] (1-1) Greenhouse The interior of the green house 10 is mainly provided with structure 600A, structure 600B, structure 600C, and structure 600D. The interior of the green house 10 is divided into an inside I18 of structure 600A, an inside I19 of structure 600B, an inside I20 of structure 600C, an inside I21 of structure 600D, and space I22. Space I22 is outside structure 600A, structure 600B, structure 600C, and structure 600D, and is inside the green house 10. Details of structure 600A, structure 600B, structure 600C, and structure 600D will be described later.

[0329] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I18 via a hose 117 (an example of a first hose). The air outlet of the air conditioner 11 also communicates with the inside I19 via a hose 118 (an example of a first hose). Furthermore, the air outlet of the air conditioner 11 also communicates with the inside I20 and inside I21 via a hose (an example of a first hose, not shown) different from the hoses 117 and 118. Air conditioned by the air conditioner 11 is supplied to the insides I18, I19, I20, and I21 via the hoses 117, 118, etc.

[0330] (2) Detailed Configuration The detailed configuration of the structure 600A, the structure 600B, the structure 600C, and the structure 600D will be described. The structure 600A is a variable structure that can change the state of the structure 600A by operating the structure 600A. The structure 600B is a variable structure that can change the state of the structure 600B by operating the structure 600B. The structure 600C is a variable structure that can change the state of the structure 600C by operating the structure 600C. The structure of the structure 600D is a variable structure that can change the state of the structure 600D by operating the structure 600D. The structure of the structure 600A and the structure 600C are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The structure of the structure 600A and the structure 600B are similar. The structure of the structure 600C is similar to the structure of the structure 600D. The function of the structure 600A is similar to the function of the structure 600B, the function of the structure 600C, and the function of the structure 600D.

[0331] The structure 600A and the structure 600B are disposed one above the other. The structure 600C and the structure 600D are disposed one above the other. The structure and function of the structure 600A will be described below. Figure 87 is a perspective view showing the detailed configuration of the structure 600A.

[0332] The structure 600A mainly has a front wall 210, a third guide rail 211, a fourth guide rail 212, a case 213, a left side wall 620, a right side wall 230, a rear wall 240, a ceiling 650, and a bottom plate 660. The front wall 210, the third guide rail 211, the fourth guide rail 212, the case 213, the right side wall 230, and the rear wall 240 are the same as those in the second embodiment, and therefore description thereof will be omitted.

[0333] The left side wall 620 faces the right side wall 230 and is in contact with the front wall 210, the rear wall 240, the ceiling 650, and the bottom plate 660. An opening 621 that is in communication with the hose 117 is provided in the left side wall 620. The opening 621 is an example of a supply port. The opening 621 may be provided in any of the front wall 210, the right side wall 230, the rear wall 240, the ceiling 650, or the bottom plate 660.

[0334] The ceiling 650 faces the bottom plate 660 and is in contact with the front wall 210, the left side wall 620, the right side wall 230, and the rear wall 240. The ceiling 650 is provided with a protrusion E that protrudes upward. For example, the ceiling 650 is provided with a protrusion E around each of the four corners.

[0335] The bottom plate 660 faces the ceiling 650 and is in contact with the front wall 210, the rear wall 240, the left side wall 620, and the right side wall 230. The bottom plate 660 is placed on the ground or on the floor of another structure (such as the greenhouse 10 or another adjustable structure). The bottom plate 660 is provided with a recess C that protrudes upward. For example, the recess C is provided around each of the four corners of the bottom plate 660. An opening 231 may be provided in the bottom plate 660.

[0336] The convex portion E of the ceiling 650 and the concave portion C of the bottom plate 660 are combined with each other. The configuration of the upper surface of the ceiling 650 and the configuration of the lower surface of the bottom plate 660 are combined with each other. The bottom plate 660 of the structure 600B can be combined on top of the ceiling 650 of the structure 600A.

[0337] The area where the plant P is grown is surrounded by the front wall 210, left side wall 620, right side wall 230, rear wall 240, ceiling 650, and bottom plate 660, thereby forming an inside I18. Specifically, the front wall 210 surrounds the front side of the area where the plant P is grown. The left side wall 620 surrounds the left side of the area where the plant P is grown. The right side wall 230 surrounds the right side of the area where the plant P is grown. The rear wall 240 surrounds the rear side of the area where the plant P is grown. The ceiling 650 surrounds the upper side of the area where the plant P is grown. The bottom plate 660 surrounds the lower side of the area where the plant P is grown.

[0338] The inside I18 is isolated from the outside of the structure 600A and the passage 102 by the front wall 210, left side wall 620, right side wall 230, rear wall 240, ceiling 650, and bottom plate 660. The front wall 210, left side wall 620, right side wall 230, rear wall 240, ceiling 650, and bottom plate 660 provide a barrier between the inside I18 and the outside of the structure 600A and the passage 102. It is difficult for people, equipment, and air to pass from the outside of the structure 600A and the passage 102 to the inside I18. Therefore, air supplied to the inside I18 through the opening 621 is unlikely to flow from the inside I18 to the outside of the structure 600A. Air in the space I22 is also unlikely to flow to the inside I18. It is difficult for people or equipment to access the inside I18. People or equipment cannot secure a working space.

[0339] Plants P are grown in the inner side I18. A bottom plate 660 covering a part or the entire area of ​​the inner side I18 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I18, the plants P are planted in soil or immersed in the nutrient solution.

[0340] Examples of the configuration of the left side wall 620 and the ceiling 650 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 a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0341] The left side wall 620 and the ceiling 650 include a transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I22 can be transmitted to the inside I18. Because the left side wall 620 and the ceiling 650 are transparent or semi-transparent, the plants P on the inside I18 can be seen through from the outside of the structure 600A.

[0342] The depth of the structure 600A is a value that ensures D77 and D78. D77 is the shortest distance in the X direction from the plant P to the front wall 210 when the plant P has finished growing. D77 is preferably 1 to 10 centimeters, but is not limited to this. D78 is the shortest distance in the negative X direction from the plant P to the rear wall 240 when the plant P has finished growing. D78 is preferably 1 to 10 centimeters, but is not limited to this.

[0343] The height of the structure 600A is a value that ensures D79, which is the shortest distance in the Y direction from the plant P to the ceiling 650 when the plant P has finished growing. D79 is preferably, but not limited to, 1 to 10 centimeters.

[0344] The width of the structure 600A is a value that ensures D80 and D81. D80 is the shortest distance in the negative Z direction from the plant P to the left side wall 620 when the plant P has finished growing. D80 is preferably, but not limited to, 1 to 10 centimeters. D81 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. D81 is preferably, but not limited to, 1 to 10 centimeters.

[0345] The left side wall 620, the ceiling 650, and the bottom plate 660 are components that cannot be changed in shape. The front wall 210 is a component that can be changed in shape. Therefore, the structure 600A is a variable structure. Note that at least one of the left side wall 620, the ceiling 650, and the bottom plate 660 may be a component that can be changed in shape. Below, a description will be given of a configuration of the structure 600A that is different from the configuration shown in FIG. 87.

[0346] Figure 88 is a perspective view showing the detailed configuration of the structure 600A. The state of Figure 88 is an embodiment in which the slats SL have been slid in the Z direction from the state of Figure 87. The fourteen slats SL are housed in a case 213. The outside of the structure 600A and the passage 102 communicate with the inside 118 via the front side of the structure 600A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P via the front side of the structure 600A.

[0347] 87 is also a state in which the slat SL has been slid in the minus Z direction from the state in Fig. 88. By changing the state of the front wall 210, the state in which the outside of the structure 600A and the passage 102 are connected to the inside I18 is changed to a state in which the outside of the structure 600A and the passage 102 are connected to the inside I18.

[0348] (3) Modifications A modification of the sixth embodiment will be described, focusing on the differences from the sixth embodiment, and omitting the description of the similarities to the sixth embodiment.

[0349] (3-1) Modification 6A In order to allow multiple structures 600A to be arranged side by side, the left surface of left side wall 620 and the right surface of right side wall 230 may be combined with each other. For example, a protrusion E and a recess C are provided on the left surface of left side wall 620 and the right surface of right side wall 230.

[0350] (3-2) Variation 6B The structure 600A and the structure 600B of the sixth embodiment, variation 6A, may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based aquaculture farm 70.

[0351] (3-3) Modification 6C The front wall 210 of the sixth embodiment, Modification 6A, and Modification 6B may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 211 and the fourth guide rail 212 by the control device.

[0352] (4) The feature-variable structure is a structure in which the configuration of the lower surface of the base plate 660 and the configuration of the upper surface of the ceiling 650 can be combined with each other so that multiple variable structures can be arranged one above the other.

[0353] There are cases where the height of a variable structure installed inside another structure differs from the height of the other structure. In this case, space may be wasted in the other structure. The variable structure is configured so that multiple variable structures can be arranged one above the other. Therefore, the variable structure reduces space wasted in the other structure and can achieve energy savings for cultivating plants P, etc.

[0354] <Seventh embodiment> (1) Overall configuration The overall configuration of the facility 7 according to the seventh embodiment will be described. Below, similarities between the sixth embodiment and the seventh embodiment will be omitted, and differences between the sixth embodiment and the seventh embodiment will be mainly described. Figure 89 is a schematic diagram showing the overall configuration of the facility 7 according to the seventh embodiment. The facility 7 mainly includes a greenhouse 10 and an air conditioner 11.

[0355] (1-1) Greenhouse The interior of the green house 10 is mainly provided with structure 700A, structure 700B, structure 700C, and structure 700D. The interior of the green house 10 is divided into an inside I23 of structure 700A, an inside I24 of structure 700B, an inside I25 of structure 700C, an inside I26 of structure 700D, and space I27. Space I27 is outside structure 700A, structure 700B, structure 700C, and structure 700D, and is inside the green house 10. Details of structure 700A, structure 700B, structure 700C, and structure 700D will be described later.

[0356] (1-2) Air Conditioner The air outlet of the air conditioner 11 is connected to the insides I23, I24, I25, and I26 via hoses (an example of a first hose, not shown). Air conditioned by the air conditioner 11 is supplied to the insides I23, I24, I25, and I26 via the hoses or the like.

[0357] (2) Detailed Configuration The detailed configuration of the structure 700A, the structure 700B, the structure 700C, and the structure 700D will be described. The structure 700A is a variable structure that can change the state of the structure 700A by operating the structure 700A. The structure 700B is a variable structure that can change the state of the structure 700B by operating the structure 700B. The structure 700C is a variable structure that can change the state of the structure 700C by operating the structure 700C. The structure 700D is a variable structure that can change the state of the structure 700D by operating the structure 700D.

[0358] The structure of structure 700A and the structure of structure 700C are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The structure of structure 700B and the structure 700D are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The structure of structure 700A and the structure 700B are similar except for their heights. The functions of structure 700A, structure 700B, structure 700C, and structure 700D are similar.

[0359] The structure 700A and the structure 700B are arranged one above the other. The structure 700C and the structure 700D are arranged one above the other. The structure and function of the structure 700A will be described below. Figure 90 is a perspective view showing the detailed configuration of the structure 700A.

[0360] The structure 700A mainly has a front wall 310, a third guide rail 311, a fourth guide rail 312, a left side wall 320, a right side wall 330, a rear wall 340, a ceiling 350, and a bottom plate 760. The front wall 310, the third guide rail 311, the fourth guide rail 312, the left side wall 320, the right side wall 330, the rear wall 340, and the ceiling 350 are the same as those in the third embodiment, and therefore description thereof will be omitted.

[0361] The upper surface of the ceiling 350 is flat. The bottom plate 760 faces the ceiling 350 and contacts the front wall 310, the left side wall 320, the right side wall 330, and the rear wall 340. The lower surface of the bottom plate 760 is flat. The bottom plate 760 is placed on the ground or on the floor of another structure (such as the greenhouse 10 or another adjustable structure). At least one of the openings 341 and 342 may be provided in the bottom plate 760.

[0362] The configuration of the upper surface of the ceiling 350 and the configuration of the lower surface of the bottom plate 760 can be combined with each other. The bottom plate 760 of the structure 700B can be combined on top of the ceiling 350 of the structure 700A.

[0363] The area where the plant P is grown is surrounded by a front wall 310, a left wall 320, a right wall 330, a rear wall 340, a ceiling 350, and a bottom plate 760, thereby forming an inside I23. Specifically, the front wall 310 surrounds the front side of the area where the plant P is grown. The left wall 320 surrounds the left side of the area where the plant P is grown. The right wall 330 surrounds the right side of the area where the plant P is grown. The rear wall 340 surrounds the rear side of the area where the plant P is grown. The ceiling 350 surrounds the upper side of the area where the plant P is grown. The bottom plate 760 surrounds the lower side of the area where the plant P is grown.

[0364] The inside I23 is isolated from the outside of the structure 700A and the passage 102 by the front wall 310, left side wall 320, right side wall 330, rear wall 340, ceiling 350, and bottom plate 760. The front wall 310, left side wall 320, right side wall 330, rear wall 340, ceiling 350, and bottom plate 760 provide a barrier between the inside I23 and the outside of the structure 700A and the passage 102. It is difficult for people, equipment, and air to pass from the outside of the structure 700A and the passage 102 to the inside I23. Therefore, air supplied to the inside I23 through the opening 341 is unlikely to flow from the inside I23 to the outside of the structure 700A. Air in the space I27 is also unlikely to flow to the inside I23. It is difficult for people or equipment to access the inside I23. People or equipment cannot secure a working space.

[0365] Plants P are grown in the inner side I23. A bottom plate 760 in a part of the inner side I23 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I23, the plants P are planted in soil or immersed in the nutrient solution.

[0366] The depth of the structure 700A is a value that ensures D82 and D83. D82 is the shortest distance in the X direction from the plant P to the front wall 310 when the plant P has finished growing. D82 is preferably 1 to 10 centimeters, but is not limited to this. D83 is the shortest distance in the negative X direction from the plant P to the rear wall 340 when the plant P has finished growing. D83 is preferably 1 to 10 centimeters, but is not limited to this.

[0367] The height of the structure 700A is a value that ensures D84, which is the shortest distance in the Y direction from the plant P to the ceiling 350 when the plant P has finished growing. D84 is preferably, but not limited to, 1 to 10 centimeters.

[0368] The width of the structure 700A is a value that ensures D85 and D86. D85 is the shortest distance in the negative Z direction from the plant P to the left side wall 320 when the plant P has finished growing. D85 is preferably, but not limited to, 1 to 10 centimeters. D86 is the shortest distance in the Z direction from the plant P to the right side wall 330 when the plant P has finished growing. D86 is preferably, but not limited to, 1 to 10 centimeters.

[0369] The bottom plate 760 is a component that cannot be changed in shape. The front wall 310 is a component that can be changed in shape. Therefore, the structure 700A is a variable structure. Note that the bottom plate 760 may also be a component that can be changed in shape. Various aspects of the structure 700A will be described below.

[0370] FIG. 91 is a perspective view showing the detailed configuration of the structure 700A. In the state shown in FIG. 91, the left slat SL has been slid in the Z direction from the state shown in FIG. 90. Because the left slat SL has been slid in the Z direction, it is generally aligned with the right slat SL in the X direction. The interior I23 is now connected to the outside of the structure 700A and the passage 102 through the left front side of the structure 700A. By changing the state of the front wall 310, the state where the outside of the structure 700A, the passage 102, and the interior I23 were blocked off has been changed to a state where the outside of the structure 700A, the passage 102, and the interior I23 are now connected. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 700A.

[0371] Figure 92 is a perspective view showing the detailed configuration of the structure 700A. In the state shown in Figure 92, the right slat SL has been slid in the negative Z direction from the state shown in Figure 91. Because the right slat SL has been slid in the negative Z direction, it is generally aligned with the left slat SL in the X direction. The interior I23 is now connected to the outside of the structure 700A and the passage 102 through the right front side of the structure 700A. By changing the state of the front wall 310, the state where the outside of the structure 700A, the passage 102, and the interior I23 were blocked off has been changed to a state where the outside of the structure 700A, the passage 102, and the interior I23 are now connected. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 700A.

[0372] 90 is a state in which the left slat SL has been slid in the minus Z direction from the state in Fig. 91. By changing the state of the front wall 310, the state in which the outside of the structure 700A and the passage 102 are connected to the inside I23 is changed to a state in which the outside of the structure 700A and the passage 102 are blocked from the inside I23.

[0373] 90 is also an embodiment in which the right slat SL has been slid in the Z direction from the embodiment in Fig. 92. By changing the embodiment of the front wall 310, the state in which the outside of the structure 700A and the passage 102 are connected to the inside I23 is changed to a state in which the outside of the structure 700A and the passage 102 are blocked from the inside I23.

[0374] (3) Modifications A modification of the seventh embodiment will be described, focusing on the differences from the seventh embodiment, and omitting the description of the similarities to the seventh embodiment.

[0375] (3-1) Modification 7A In order to allow multiple structures 700A to be arranged side by side, the left surface of the left side wall 320 and the right surface of the right side wall 330 may be combined with each other. For example, the left surface of the left side wall 320 and the right surface of the right side wall 330 are flat surfaces.

[0376] (3-2) Variation 7B The structures 700A and 700B of the seventh embodiment, variation 7A, may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based aquaculture farm 70.

[0377] (3-3) Modification 7C The front wall 310 of the seventh embodiment, Modification 7A, and Modification 7B may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 311 and the fourth guide rail 312 by the control device.

[0378] <Fourth Embodiment> (1) Overall Configuration The overall configuration of the facility 8 according to the eighth embodiment will be described. Hereinafter, similarities between the fifth and eighth embodiments will be omitted, and differences between the fifth and eighth embodiments will be mainly described. Figure 93 is a schematic diagram showing the overall configuration of the facility 8 according to the eighth embodiment. The facility 8 mainly includes a greenhouse 10 and an air conditioner 11.

[0379] (1-1) Greenhouse The interior of the green house 10 is mainly provided with structure 800A, structure 800B, structure 800C, and structure 800D. The interior of the green house 10 is divided into an inside I28 of structure 800A, an inside I29 of structure 800B, an inside I30 of structure 800C, an inside I31 of structure 800D, and space I32. Space I32 is outside structure 800A, structure 800B, structure 800C, and structure 800D, and is inside the green house 10. Details of structure 800A, structure 800B, structure 800C, and structure 800D will be described later.

[0380] (1-2) Air Conditioner The air outlet of the air conditioner 11 is connected to the inside I28 via a hose 111 (an example of a first hose). The air outlet of the air conditioner 11 is also connected to the inside I29, the inside I30, and the inside I31 via other hoses (an example of a first hose, not shown). Air conditioned by the air conditioner 11 is supplied to the insides I28, I29, I30, and I31 via the hoses 111 and the like.

[0381] (2) Detailed Configuration The detailed configuration of the structure 800A, the structure 800B, the structure 800C, and the structure 800D will be described. The structure 800A is a variable structure that can change the state of the structure 800A by operating the structure 800A. The structure 800B is a variable structure that can change the state of the structure 800B by operating the structure 800B. The structure 800C is a variable structure that can change the state of the structure 800C by operating the structure 800C. The structure 800D is a variable structure that can change the state of the structure 800D by operating the structure 800D.

[0382] The structure of the structure 800A and the structure of the structure 800B are approximately plane symmetrical with respect to a plane extending in the Y direction and the X direction. The structure of the structure 800A and the structure 800C are approximately plane symmetrical with respect to a plane extending in the Y direction and the Z direction. The structure of the structure 800C and the structure 800D are approximately plane symmetrical with respect to a plane extending in the Y direction and the X direction. The functions of the structure 800A, the structure 800B, the structure 800C, and the structure 800D are similar. The structure and function of the structure 800A will be described below. Figure 94 is a perspective view showing the detailed configuration of the structure 800A.

[0383] The structure 800A mainly has a front wall 410, a left side wall 420, a right side wall 430, a rear wall 440, a ceiling 450, a bottom plate 860, and a rotation axis AX. The front wall 410, the left side wall 420, the right side wall 430, the rear wall 440, the ceiling 450, and the rotation axis AX are the same as those in the fourth embodiment, and therefore description thereof will be omitted.

[0384] The bottom plate 860 faces the ceiling 450 and is in contact with the front wall 410, the left side wall 420, the right side wall 430, and the rear wall 440. The bottom plate 860 is placed on the ground or on the floor of another structure (such as the greenhouse 10 or another adjustable structure). At least one of the openings 421 and 431 may be provided in the bottom plate 860.

[0385] The area where the plant P is grown is surrounded by a front wall 410, a left wall 420, a right wall 430, a rear wall 440, a ceiling 450, and a bottom plate 860, thereby forming an inside I28. Specifically, the front wall 410 surrounds the front side of the area where the plant P is grown. The left wall 420 surrounds the left side of the area where the plant P is grown. The right wall 430 surrounds the right side of the area where the plant P is grown. The rear wall 440 surrounds the rear side of the area where the plant P is grown. The ceiling 450 surrounds the upper side of the area where the plant P is grown. The bottom plate 860 surrounds the lower side of the area where the plant P is grown.

[0386] The inside I28 is isolated from the outside of the structure 800A and the passage 102 by the front wall 410, left side wall 420, right side wall 430, rear wall 440, ceiling 450, and bottom plate 860. The front wall 410, left side wall 420, right side wall 430, rear wall 440, ceiling 450, and bottom plate 860 provide a barrier between the inside I28 and the outside of the structure 800A and the passage 102. It is difficult for people, equipment, and air to pass from the outside of the structure 800A and the passage 102 to the inside I28. Therefore, air supplied to the inside I28 through the opening 421 is unlikely to flow from the inside I28 to the outside of the structure 800A. Air in the space I32 is also unlikely to flow to the inside I28. It is difficult for people or equipment to access the inside I28. People or equipment cannot secure a working space.

[0387] Plants P are grown in the inner side I28. A bottom plate 860 in a part of the inner side I28 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I28, the plants P are planted in soil or immersed in the nutrient solution.

[0388] The depth of the structure 800A is a value that ensures D87 and D88. D87 is the shortest distance in the X direction from the plant P to the front wall 410 when the plant P has finished growing. D87 is preferably 1 to 10 centimeters, but is not limited to this. D88 is the shortest distance in the negative X direction from the plant P to the rear wall 440 when the plant P has finished growing. D88 is preferably 1 to 10 centimeters, but is not limited to this.

[0389] The height of the structure 800A is a value that ensures D89, which is the shortest distance in the Y direction from the plant P to the ceiling 450 when the plant P has finished growing. D89 is preferably, but not limited to, 1 to 10 centimeters.

[0390] The width of the structure 800A is a value that ensures D90 and D91. D90 is the shortest distance in the negative Z direction from the plant P to the left side wall 420 when the plant P has finished growing. D90 is preferably, but not limited to, 1 to 10 centimeters. D91 is the shortest distance in the Z direction from the plant P to the right side wall 430 when the plant P has finished growing. D91 is preferably, but not limited to, 1 to 10 centimeters.

[0391] The bottom plate 860 is a component that cannot be changed in shape. The front wall 410 and the ceiling 450 are components that can be changed in shape. Therefore, the structure 800A is a variable structure. Note that the bottom plate 860 may also be a component that can be changed in shape. Below, a description will be given of a configuration of the structure 800A that is different from the configuration shown in FIG. 94 .

[0392] Figure 95 is a perspective view showing the detailed configuration of the structure 800A. The state of Figure 95 is an state in which the ceiling 450 has been rotated around the rotation axis AX from the state of Figure 94. The ceiling 450 has been rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. As the ceiling 450 has been rotated, the front wall 410 has also been rotated along with the ceiling 450.

[0393] The inside I28 of the structure 800A is in a state of communication with the outside of the structure 800A and the passage 102 via the front and upper sides. By changing the configuration of the ceiling 450 and the front wall 410, the state in which the outside of the structure 800A and the passage 102 were isolated from the inside I28 has been changed to a state in which the outside of the structure 800A and the passage 102 are in communication with the inside I28. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P via the front and upper sides of the structure 800A.

[0394] 94 is a configuration in which the ceiling 450 is rotated about the rotation axis AX from the configuration of the structure 800A in Fig. 95. The ceiling 450 is rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. Since the ceiling 450 is rotated, the front wall 410 is also rotated along with the ceiling 450.

[0395] By changing the configuration of the ceiling 450 and the front wall 410, the state in which the outside of the structure 800A and the passage 102 are connected to the inside I28 has been changed to a state in which the outside of the structure 800A and the passage 102 are blocked from the inside I28.

[0396] (3) Modifications A modification of the eighth embodiment will be described, focusing on the differences from the eighth embodiment, and omitting the description of the similarities to the eighth embodiment.

[0397] (3-1) Modification 8A The structures 800A, 800B, 800C, and 800D may be provided on a support base Su and used for so-called elevated cultivation. Figure 96 is a schematic diagram showing the overall configuration of the facility 8 according to modification 8A.

[0398] (3-2) Variant 8B The structure 800A, the structure 800B, the structure 800C, and the structure 800D of the eighth embodiment and variant 8A may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based aquaculture farm 70.

[0399] (3-3) Modification 8C The front wall 410 and the ceiling 450 of the eighth embodiment, Modification 8A, and Modification 8B may be changed in appearance under the control of a control device (not shown). In other words, the front wall 410 and the ceiling 450 may be rotated around the rotation axis AX under the control of the control device.

[0400] Although the embodiments of the present disclosure have been described above, it will be understood that various changes in form and details can be made without departing from the spirit and scope of the present disclosure as defined in the claims.

[0401] The variable structure according to the present disclosure can be industrially applied according to the embodiments of the present disclosure.
