[0009] Hereinafter, an embodiment of the cultivation house according to the present disclosure will be described with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] FIG. 1 is a front view showing an example of a cultivation house 100 according to this embodiment. FIG. 2 is a plan view showing an example of the internal configuration of the cultivation house 100. The cultivation house 100 shown in FIG. 1 and FIG. 2 is built, for example, on an outdoor ground surface G, and cultivates a plant P by mainly taking in natural light such as sunlight. The plant P is, for example, strawberry, but is not limited to strawberry and may be other types of plants. The cultivation house 100 includes a building 10, a cultivation shelf 20, an enclosure member 30, a temperature adjustment device 40, and a gap filling member 50.

[0011] The building 10 houses the plant P to be cultivated. The building 10 transmits light of a wavelength that allows the plant P to perform photosynthesis. The building 10 is formed using a transparent material such as vinyl or glass. The material constituting the building 10 is not limited to the above, and other materials may be used as long as they transmit light of a wavelength that allows the plant P to perform photosynthesis. The building 10 is arranged in a stretched state on a frame 11 that serves as a framework. The building 10 has a front part 10a and a back part 10b that serve as gables, side parts 10c and 10d, and a ceiling part 10e. A door (not shown) is arranged on either the front part 10a, the back part 10b, or the side parts 10c and 10d of the building 10.

[0012] The building 10 is provided with a ventilation device 12, a light shielding sheet 13, and a heat insulating curtain 14. The ventilation device 12 takes in air from outside the building 10 and exhausts the air from inside the building 10 to the outside through an exhaust port (not shown). The building 10 may be configured such that a lining is provided along the ceiling portion 10e at a position below the ventilation device 12. In this case, the lining is arranged so as to separate the space in which the plant P is accommodated from the space in the ceiling portion along the ceiling portion 10e. The ventilation device 12 takes in air into the space in the ceiling portion and exhausts the air from the space through an exhaust port (not shown) provided in the space in the ceiling portion. With this configuration, the ventilation device 12 takes in outside air into the space in the ceiling portion, thereby controlling the temperature of the space in which the plant P is accommodated through the lining.

[0013] The shading sheet 13 can be disposed, for example, below the ceiling portion 10e of the building 10. The shading sheet 13 reflects or absorbs at least a portion of light such as sunlight. The shading sheet 13 may be switchable between, for example, a covered state in which it covers at least a portion of the lower part of the ceiling portion 10e, and an open state in which it does not cover the lower part of the ceiling portion 10e.

[0014] The heat insulating curtain 14 can be disposed, for example, on the outside of the side portions 10c, 10d of the building 10. The heat insulating curtain 14 reflects or absorbs at least a part of the heat input due to sunlight or the like. The heat insulating curtain 14 may be switchable between, for example, a covered state in which at least a part of the side portions 10c, 10d is covered, and an open state in which the side portions 10c, 10d are not covered. In addition, when sunlight is not irradiated or the sunlight is weak, the heat insulating curtain 14 serves as a heat shield, thereby reducing the amount of heat entering and leaving the building 10. This can prevent the temperature inside the building 10 from becoming too high in summer, and the temperature inside the building 10 from becoming too low in winter, for example.

[0015] The cultivation shelf 20 is placed inside the building 10, and a plant P is placed thereon. The cultivation shelf 20 has a shelf portion 21 and a support portion 22. The plant P and soil for planting the plant P are placed on the shelf portion 21. The support portion 22 supports the shelf portion 21.

[0016] The cultivation shelves 20 are formed so that their length is in the first direction D1. The plants P are arranged on the cultivation shelves 20 so that multiple plants P are lined up in the first direction D1. Multiple cultivation shelves 20 are arranged in one building 10 in a second direction D2 perpendicular to the first direction D1 along a horizontal plane. The first direction D1 and the second direction D2 are each perpendicular to the up-down direction D3. Each cultivation shelf 20 is provided so as to be movable in the second direction D2. For example, the support part 22 is provided with wheels 22a at the bottom. A rail (not shown) that guides the wheels 22a in the second direction D2 is provided on the ground of the building 10. By moving the wheels 22a along the rail, the cultivation shelf 20 can be moved in the second direction D2. By moving the cultivation shelves 20 in the second direction D2, a space for an operator to enter between the cultivation shelves 20 can be secured. Therefore, the cultivation shelves 20 can be efficiently arranged in the second direction D2 in the building 10.

[0017] At least one of the multiple cultivation shelves 20 is provided with a temperature detection unit (not shown). The temperature detection unit detects the temperature of a portion of the cultivation shelf 20 surrounded by the enclosing member 30. The temperature detection unit can transmit the detection result to the temperature adjustment device 40. The temperature detection units can be configured to be disposed, for example, on every other cultivation shelf 20 arranged in the second direction D2. Note that the arrangement of the temperature detection units is not limited to the above and may be other arrangements.

[0018] The enclosing member 30 is provided for each cultivation shelf 20. Fig. 3 to Fig. 8 are diagrams showing an example of the enclosing member 30. The enclosing member 30 is supported by the cultivation shelf 20, and moves integrally with the cultivation shelf 20 when the cultivation shelf 20 moves in the second direction D2. The enclosing member 30 is configured to enclose the sides of the plant P so that the upper side of the plant P is open to the inside of the building 10.

[0019] As shown in Fig. 3, the enclosing member 30 can be configured to enclose at least a height range H covering the entire plant P. The enclosing member 30 may be configured to enclose at least a height range HL of the plant P from the upper end of the cultivation shelf 20 to the leaf PL arranged at the lowest position. The enclosing member 30 may also be configured to enclose at least a height range HC of a root portion PC of the plant P extending from the upper end of the cultivation shelf 20. The enclosing member 30 has an upper opening portion 30a that opens up the upper side of the plant P. The enclosing member 30 also has a side opening portion 30b that opens up one of the sides of the plant P in a second direction.

[0020] In this embodiment, the enclosing member 30 encloses the bottom of the cultivation shelf 20 and three sides of the cultivation shelf 20 excluding the side in the second direction D2 where the lateral opening portion 30b is located. The enclosing member 30 has a bottom 31, walls 32, 33, 34, 35, and a partition 36. The bottom 31 is disposed below the cultivation shelf 20, and the walls 32, 33, 34, 35 are provided in a state of extending upward from the bottom 31. The bottom 31 is disposed with a gap between it and, for example, the lower portion of the cultivation shelf 20.

[0021] The enclosing member 30 is capable of retaining a temperature-controlled gas in a space K (hereinafter referred to as a retaining space K) surrounded by a bottom 31 and walls 32, 33, 34, and 35. The retaining space K is a space partitioned by the bottom 31, walls 32, 33, 34, and 35, an upper opening 30a, and a side opening 30b. The enclosing member 30 is provided so that the entire plant P is accommodated in the retaining space K.

[0022] The walls 32, 33, 34, and 35 are provided protruding upward from the cultivation shelf 20. The wall 32 is arranged on one side of the cultivation shelf 20 in the first direction D1. The wall 33 is arranged on the other side of the cultivation shelf 20 in the first direction D1. The wall 34 is arranged on one side of the cultivation shelf 20 in the second direction D2. The wall 35 is arranged on the other side of the cultivation shelf 20 in the second direction D2.

[0023] The side opening portion 30b is provided on the wall portion 34. The wall portions 32, 33, and 35 are generally in the same height (position in the third direction D3). The wall portion 34 is lower in height than the walls 32, 33, and 35. A step is formed between the wall portion 34 and the walls 32 and 33 that are in contact with the wall portion 34 in the first direction D1 due to the difference in height. This step is formed as the side opening portion 30b. The height of the wall portion 34 can be, for example, equal to the height of the upper end of the cultivation shelf 20 or lower than the height of the upper end of the cultivation shelf 20. By providing the side opening portion 30b, it becomes easier for an operator to access the cultivation shelf 20 from one side of the second direction D2. This contributes to improving work efficiency. The side opening portion 30b is arranged on the same side of the second direction D2 in the enclosing member 30 (the right side in the examples of FIGS. 1 to 6).

[0024] The dimensions of the walls 32, 33, 35 in the vertical direction D3 are set so that, for example, when the plant P is surrounded, the walls are higher than the height range H of the entire plant P. This allows the temperature-adjusting gas to spread throughout the entire plant P in the height direction.

[0025] The partition 36 is disposed inside the enclosing member 30. The partition 36 is disposed between the cultivation shelf 20 and the bottom 31 of the enclosing member 30 in the third direction D3. The partition 36 is disposed so as to divide the holding space K into upper and lower spaces in the third direction D3. The partition 36 forms an upper space K1 above the partition 36, and forms a lower space K2 below the partition 36. The partition 36 has a through-hole 36a penetrating in the third direction D3. The through-hole 36a is disposed on both sides of the cultivation shelf 20 in the second direction D2. A plurality of through-holes 36a are disposed in the first direction D1. The upper space K1 and the lower space K2 are connected via the through-hole 36a. In addition, the wall portions 32, 33, 34, 35 and the partition member 36 of the enclosing member 30 may be entirely or partially formed using a material such as polystyrene foam. In this case, the workability of the enclosing member 30 can be improved, and the enclosing member 30 can be easily manufactured using inexpensive materials, thereby reducing costs.

[0026] The temperature adjustment device 40 supplies a temperature adjustment gas to the holding space K surrounded by the enclosing member 30. The temperature adjustment device 40 includes a pipe 41 and a supply device .

[0027] The piping 41 is provided for each cultivation shelf 20. The piping 41 is connected from the header 43 of the supply device 42 to the lower space K2 via the wall portion 32 of the enclosing member 30. For example, the piping 41 may be provided such that a portion from a connection portion with the header 43 to a connection portion with the wall portion 32 can be deformed in response to movement of the cultivation shelf 20 in the second direction D2.

[0028] The supply device 42 adjusts (e.g., cools) the temperature of gas inside or outside the building 10, and supplies the temperature-adjusted gas to the piping 41. The supply device 42 is disposed in a position on the first direction D1 relative to the cultivation shelf 20. In this embodiment, the temperature adjustment device 40 is disposed in a position on one side of the first direction D1 relative to the cultivation shelf 20. This saves space for arranging the temperature adjustment device 40 in the building 10, and accordingly, the space for arranging the cultivation shelf 20 can be expanded, and the production volume of the plant P can be increased.

[0029] The supply device 42 is connected to a plurality of pipes 41 via a header 43. The supply device 42 supplies temperature-controlled gas to the lower space K2 of the enclosure member 30 via the header 43 and the plurality of pipes 41. The supply device 42 may adjust the temperature of the temperature-controlled gas depending on the detection result of the detection unit 25. The temperature-controlled gas supplied to the lower space K2 flows through the lower space K2 in the first direction D1, and is supplied to the upper space K1 from the through-hole 36a. The temperature around the plant P is adjusted by the temperature-controlled gas supplied to the upper space K1.

[0030] 3 and 4, the gap filling member 50 is disposed along the first direction D1 below the side opening 30b of an enclosing member 30 (hereinafter sometimes referred to as the first enclosing member 30A) so as to eliminate a gap portion generated between the first enclosing member 30A and the second enclosing member 30B when the enclosing member 30 and the second enclosing member 30B are disposed adjacent to each other in the second direction D2 in which the side opening 30b is disposed. The gap filling member 50 is disposed for the purpose of suppressing leakage of the temperature control gas from the first enclosing member 30A when the first enclosing member 30A and the second enclosing member 30B are disposed adjacent to each other. The gap filling member 50 is formed in a sheet shape in Figs. 3, 4, 7, and 8, has flexibility, and is arranged in a state where the sheet extends upward from the lower part of the first surrounding member 30A, and is convex upward and bent downward toward the second surrounding member 30B. Note that the gap filling member 50 may be a sponge-like, rubber-like, or clay-like member as in the gap filling member 50A shown in Fig. 5, or a combination of these as in the gap filling members 50, 50A shown in Fig. 6. In this case, the gap filling members 50, 50A are provided so that they can fill the gap when the adjacent surrounding members 30 are brought close to each other. In addition, when the gap filling member 50 is made of a sheet with little bending, a member that bears static electricity may be provided on the wall portion 35 of the second surrounding member 30B, so that the gap filling member 50 adheres to the second surrounding member 30B by static electricity when the first surrounding member 30A and the second surrounding member 30B are brought close to each other.

[0031] 3, when the first enclosing member 30A and the second enclosing member 30B are arranged close to each other in the second direction D2, the wall 34 of the first enclosing member 30A and the wall 35 of the second enclosing member 30B are arranged close to each other. In this case, a space S1 surrounded by the walls 32, 33, 34, 35, the partition 36, the gap filling member 50, and the wall 35 of the second enclosing member 30B is formed between the first enclosing member 30A and the second enclosing member 30B. Therefore, the cultivation shelf 20 surrounded by the first enclosing member 30A has a temperature-adjusting gas held by the space S1.

[0032] As shown in FIG. 4, when the first enclosing member 30A and the second enclosing member 30B move relatively away from each other in the second direction D2, the gap filling member 50 moves together with the first enclosing member 30A and peels off from the second enclosing member 30B, forming a working space SP. In this case, the temperature control gas is not retained, but as soon as work such as harvesting or maintenance is completed, the first enclosing member 30A and the second enclosing member 30B are returned to a state in which they are close to each other, thereby minimizing the state in which the temperature control gas is not retained. In addition, when there are multiple enclosing members 30, the state in which the temperature control gas is not retained can be minimized by working in order from the enclosing member 30 at the end on one side of the second direction D2.

[0033] 7, the enclosing member 30 (hereinafter sometimes referred to as the third enclosing member 30C) disposed at one end in the second direction D2 has walls 34C, 35 on both sides in the second direction D2 that are the same or approximately the same height in the third direction D3. With this configuration, the third enclosing member 30C disposed at the end on one side in the second direction D2 can appropriately prevent the temperature control gas from leaking out to one lateral side in the second direction D2. Furthermore, even if the third enclosing member 30C is not disposed at one end in the second direction D2 as shown in FIG. 8, the enclosing member 30 on the right side of the third enclosing member 30C in the second direction D2 is provided with a side opening portion 30b on the left wall surface of the enclosing member 30, and the enclosing member 30 on the left side of the third enclosing member 30C in the second direction D2 is provided with a side opening portion 30b on the right wall surface of the enclosing member 30, so that the adjacent enclosing members 30 are placed close to each other, and the temperature-control gas can be appropriately prevented from leaking out to one side of the second direction D2. The third enclosing member 30C may have an upper portion of a side wall detachable on one side of the second direction D2, in which case the worker can easily access the cultivation shelf 20. This contributes to improving the worker's work efficiency.

[0034] In this case, in the third enclosing member 30C, an upper space K1 is formed that is surrounded by the walls 32, 33, 34C, and 35 and the partition 36. Therefore, in the cultivation shelf 20 surrounded by the third enclosing member 30C, the temperature-adjusting gas is held by the upper space K1.

[0035] FIG. 9 is a side view showing another example of the internal configuration of the cultivation house according to the present embodiment. In the cultivation house 100A shown in FIG. 9, the building 10A has an inner lining 15 and an outer lining 16. The inner lining 15 houses a plurality of cultivation shelves 20. The outer lining 16 houses the inner lining 15. In the building 10A having such a configuration, for example, a supply device 42 that generates and supplies a temperature-control gas of the temperature control device 40 and a header 43 can be disposed outside the inner lining 15 and inside the outer lining 16. In this configuration, the piping 41 connected from the header 43 penetrates the inside and outside of the inner lining 15 and is connected to the lower space K2 of the enclosure member 30 disposed inside the inner lining 15.

[0036] The outer lining 16 has a light-shielding portion 16a and a heat-insulating portion 16b. The light-shielding portion 16a reflects or absorbs at least a part of the light L, such as sunlight, irradiated to the supply device 42. By providing the light-shielding portion 16a, irradiation of the light L to the supply device 42 is suppressed. In the configuration shown in FIG. 9, the supply device 42 is disposed outside the lining 15, that is, at a position separated from the cultivation shelf 20 and the lining 15. Therefore, the light-shielding portion 16a can be disposed so that the light L irradiated to the cultivation shelf 20 is not blocked. In addition, the heat-insulating portion 16b can suppress heat input C from the outside of the outer lining 16. At least one of the light-shielding portion 16a and the heat-insulating portion 16b does not need to be provided.

[0037] 9, the supply device 42 may have a suction pipe 44 connected to the inside of the lining 15. The suction pipe 44 penetrates the inside and outside of the lining 15 separately from the piping 41. The supply device 42 can suck air inside the lining 15 via the suction pipe 44 and supply it to the lower space K2 of the enclosing member 30. With this configuration, the air inside the lining 15, i.e., air that is relatively close to a temperature-controlled state after its temperature is controlled by the temperature-controlling gas, can be reused, so that the power consumption required for temperature control can be reduced compared to the case where air outside the lining 15 is used.

[0038] As described above, according to the first aspect of the present disclosure, a cultivation house is provided which comprises a light-transmitting building 10, cultivation shelves 20 arranged inside the building 10 and formed so as to be longitudinal in a first direction D1 in a planar view, housing plants to be cultivated and arranged in multiple in a second direction D2 intersecting the first direction D1 in a planar view, an enclosure member 30 provided on the cultivation shelf 20 and surrounding the sides of the plants, and a temperature control device 40 that supplies temperature-control gas to the space surrounded by the enclosure member 30, wherein in at least one cultivation shelf 20, the enclosure member 30 has a side opening portion 30b that opens one of the sides of the plant in the second direction D2, and is formed so as to surround three sides, both in the first direction D1 and the other in the second direction D2.

[0039] According to this configuration, since at least one of the enclosing members 30 has a side opening portion 30b, an operator can easily access the cultivation shelf 20 from the side opening portion 30b. This contributes to improving the work efficiency of the operator. In addition, since the configuration is such that a plurality of cultivation shelves 20 are arranged in the second direction D2 and the enclosing members 30 are configured to enclose the cultivation shelves 20, the enclosing member 30 provided with the side opening portion 30b can be in an enclosed state in which one side in the second direction D2 is covered by the side wall of the adjacent enclosing member 30. Therefore, leakage of the temperature control gas from the space enclosed by the enclosing member 30 can be suppressed.

[0040] According to the second aspect of the present disclosure, in the cultivation house relating to the first aspect, the side opening portion 30b is provided in a plurality of cultivation shelves 20, and in each cultivation shelf 20 having the side opening portion 30b, the side opening portion 30b is arranged on the same side of the second direction D2.

[0041] According to this configuration, it is possible to form a plurality of patterns in the second direction D2 in which the side opening portion 30b of the surrounding member 30 is covered by the wall portion of the adjacent surrounding member 30 on one side in the second direction D2.

[0042] According to the third aspect of the present disclosure, in the cultivation house according to the first or second aspect, the plurality of cultivation shelves 20 are movable in the second direction D2.

[0043] According to this configuration, the adjacent surrounding member 30 can be easily placed close to the side opening 30b.

[0044] According to a fourth aspect of the present disclosure, in a cultivation house relating to any of the first to third aspects, a first enclosing member 30A, which is an enclosing member 30 having a side opening 30b, and a second enclosing member 30B, which is an enclosing member 30 adjacent to the first enclosing member 30A on one side of the second direction D2 in which the side opening 30b is arranged, are brought into close proximity to each other, and a gap filling member 50 is arranged along the first direction D1 at the bottom of the side opening 30b so as to eliminate any gap that occurs between the enclosing members 30A and 30B.

[0045] According to this configuration, the gap filling member 50 can prevent the temperature control gas from leaking out from between the first enclosing member 30A and the second enclosing member 30B.

[0046] According to a fifth aspect of the present disclosure, in the cultivation house according to the fourth aspect, the gap filling member 50 is formed in a sheet shape and has flexibility.

[0047] According to this configuration, when the first enclosing member 30A and the second enclosing member 30B move relatively away from each other in the second direction D2, the gap filling member 50 moves together with the first enclosing member 30A and peels off from the second enclosing member 30B, thereby forming a work space.

[0048] According to a sixth aspect of the present disclosure, in a cultivation house relating to any of the first to fifth aspects, the enclosure member 30 has a partition portion 36 below the cultivation shelf 20 that divides the interior of the enclosure member 30 into an upper space K1 and a lower space K2 each extending in a first direction D1, the partition portion 36 has a through portion 36a connecting the upper space K1 and the lower space K2, and the temperature control device 40 has a piping 41 connected to the lower space K2 and a supply device 42 that circulates a temperature control gas to the lower space K2 via the piping 41.

[0049] According to this configuration, the lower space K2 through which the temperature-adjusted gas flows is provided integrally with the surrounding member 30, so there is no need to arrange separate piping or the like in the surrounding member 30. This makes it possible to reduce the number of parts of the surrounding member 30 and simplify the configuration.

[0050] According to the seventh aspect of the present disclosure, in a cultivation house relating to the sixth aspect, the building 10 has an inner lining 15 that houses a plurality of cultivation shelves 20 and an outer lining 16 that houses the inner lining 15, and a supply device 42 that generates and supplies a temperature-regulating gas is arranged outside the inner lining 15 and inside the outer lining 16.

[0051] According to this configuration, the influence of heat generation or the like in the supply device 42 can be prevented from reaching the inside of the lining 15 .

[0052] According to an eighth aspect of the present disclosure, in the cultivation house related to the seventh aspect, the outer cover 16 has at least one of a light-shielding portion 16a and a heat-insulating portion 16b arranged corresponding to the supply device .

[0053] According to this configuration, the light blocking portion 16a and the heat insulating portion 16b can prevent the temperature of the supply device 42 from becoming too high.

[0054] According to the ninth aspect of the present disclosure, in a cultivation house relating to the seventh or eighth aspect, the supply device 42 has a suction pipe 44 connected to the inside of the lining 15, and is capable of sucking in air inside the lining 15 through the suction pipe 44, and supplies the sucked air inside the lining 15 to the lower space K2.

[0055] According to this configuration, air inside the lining 15, that is, air that has been temperature-adjusted and is in a relatively temperature-adjusted state, is sucked in and supplied to the lower space K2, so that the power consumption required for temperature adjustment can be reduced.
