A fifth wall 35 is provided. That is, the house 2 has a total of five walls 3 including a first wall 31 to a fifth wall 35. The internal space 20 surrounded by the five walls 3 and the ground is mainly used as a cultivation space or a cultivation space.

  In the first embodiment, as shown in FIG. 2, the house 2 has a square shape in a plan view, and is arranged such that outward normals of each side face east, west, south, and north. 1, 2, 4, and 5, arrow S indicates south, arrow W indicates west, arrow N indicates north, and arrow E indicates east. In plan view, the walls 3 located on the sides whose outward normals face the south S, west W, north N, and east E are the first wall 31, the second wall 32, the third wall 33, and the fourth wall 34, respectively. It has become.

  In the first embodiment, as shown in FIG. 1, the first wall 31 and the third wall 33 have the same shape in which the left and right sides and the lower side are linear and the upper side is arched. The second wall 32 and the fourth wall 34 have a rectangular shape. The vertical lengths of the respective sides of the first wall 31 to the fourth wall 34 are all formed to be the same length. The fifth wall 35 constituting the ceiling is provided so that each side corresponds to the upper side of the first wall 31 to the fourth wall 34.

  A first window 41, a second window 42, a third window 43, a fourth window 44 and a fifth wall 35 are respectively formed on the first wall 31, the second wall 32, the third wall 33, the fourth wall 34 and the fifth wall 35. A window 45 is formed. That is, the house 2 includes a total of five windows 4 including a first window 41 to a fifth window 45.

  In the first embodiment, as shown in FIG. 1, the first window 41 to the fourth window 44 have a rectangular shape in which the upper side and the lower side are horizontal. In each wall 3, the first window 41 to the fourth window 44 are provided in the central portion in the left-right direction and in positions higher than the center in the vertical direction. As shown in FIGS. 1 and 2, the fifth window 45 has a rectangular shape in which each of the outward normals of each side faces the east, west, south, and north in a plan view, and is provided at the center of the fifth wall 35. .

  As shown in FIG. 1, the house 2 has a first door 51, a second door 52, a first window 41, a second window 42, a third window 43, a fourth window 44, and a fifth window 45, respectively. A third door 53, a fourth door 54, and a fifth door 55 are provided. That is, the house 2 has a total of five doors 5, that is, a first door 51 to a fifth door 55. The door 5 is formed larger than the corresponding window 4. The door 5 is rotatably supported on the wall 3 by a rotation center shaft 56 provided on one side thereof (the upper side in the case of the first door 51 to the fourth door 54), and the side opposite to the one side rotates. It has a configuration like a hinged door.

  The agricultural house 1 further includes a window opening / closing device 6 that opens and closes the window 4. As shown in FIG. 1, the window opening / closing device 6 drives the five doors 5 to open and close the five windows 4 corresponding to the doors 5, respectively. In the first embodiment, the window opening / closing device 6 includes a drive source including a motor and the like, and a power transmission mechanism including a gear and the like that transmits power generated by the drive source to the rotation center shaft 56 of the door 5. It is possible to drive the door 5 by the window opening and closing device 6 so that the house 2 is in a state in which the window 4 is opened or in a state in which the window 4 is closed. Each window 4 can be arbitrarily opened and closed independently of the open / closed state of the other windows 4. That is, the agricultural house 1 includes window opening / closing devices 61, 62, 63, 64, and 65 corresponding to the first window 41 to the fifth window 45, respectively.

  The agricultural house 1 further includes a control device 7 that controls the window opening and closing device 6. As shown in FIG. 1, the control device 7 includes a microcomputer. As shown in FIG. 3, the microcomputer includes a CPU (Central Processing Unit) 71, a storage device 72, and the like, and controls the CPU 71 by executing a program stored in the storage device 72. Can be used as appropriate.

  As shown in FIG. 2, the agricultural house 1 further includes a wind direction detector 81 that detects the wind direction around the house 2. As the wind direction detector 81, various known wind direction and wind speed sensors can be used as appropriate. The wind direction information detected by the wind direction detector 81 can be acquired and processed by the control device 7. In this case, the wind direction detector 81 or the control device 7 can be supplementarily provided with necessary devices such as an amplifier and an A / D (Analog / Digital) converter.

  The control device 7 is configured to allow ventilation control. The ventilation control means that the control device 7 opens two windows 4 formed on the two adjacent walls 3 based on the wind direction detected by the wind direction detector 81, and is formed on the remaining three walls 3. In this control, the three windows 4 are closed.

  Specifically, the combination of the two windows 4 formed on the two adjacent walls 3 includes a first window 41 and a second window 42, a second window 42 and a third window 43, a third window 43 and Fourth window 44, fourth window 44 and first window 41, first window 41 and fifth window 45, second window 42 and fifth window 45, third window 43 and fifth window 45, fourth window 44 and Each combination of the 5th window 45 is mentioned.

  Here, the technical significance of opening the two windows 4 formed on the two adjacent walls 3 will be described. Usually, as shown in FIG. 4A, an object 90 such as a cultivated product or a cultivated product is located inside the house 2, particularly over a wide area in the center. For this reason, when the south wind is blowing, the first window 41 and the third window 43 are opened, and the other windows 4 are closed, the airflow flowing from the first window 41 (see arrow 91) is routed by the object 90. Is bent into an air flow (see arrow 92) close to the second wall 32 or the fourth wall 34. Thereafter, the airflow (see arrow 92) is further bent and the airflow is directed toward the third window 43 (see arrow 93), and the airflow flows out of the third window 43 (see arrow 94).

  On the other hand, as shown in FIG. 4B, when the south wind is blowing and the first window 41 and the second window 42 are opened and the other windows are closed, the airflow flowing in from the first window 41 (arrow 95). (See) becomes an air flow (see an arrow 96) whose path is bent by the object 90 and is close to the second wall 32. However, the airflow (see arrow 96) becomes an airflow (see arrow 97) that flows out from the second window 42 as it is, and the airflow smoothly flows inside the house 2. In this case, the flow path resistance from the first window 41 to the second window 42 is smaller than the flow path resistance from the first window 41 to the third window 43 in the case shown in FIG. 4A.

  Further, when the south wind is blowing, a negative pressure lower than the atmospheric pressure is likely to be applied to the outer surfaces of the second wall 32, the fourth wall 34, and the fifth wall 35 having normal lines orthogonal to the wind direction. For this reason, when any one of the second window 42, the fourth window 44, and the fifth window 45 formed on the second wall 32, the fourth wall 34, and the fifth wall 35 is open, it is open. The window 4 can easily function as an airflow outlet. When two windows 4 formed on two adjacent walls 3 are opened, one of the second wall 32, the fourth wall 34, and the fifth wall 35 is necessarily opened. Thus, the opened window 4 among these tends to exhibit a function as an airflow outlet.

  If three or more windows 4 are opened, the airflow does not flow smoothly, and the flow resistance tends to be larger than the flow resistance from the first window 41 to the second window 42 in the case shown in FIG. 4B. .

  Furthermore, the remaining one window 4 to be opened only needs to function as an air flow inlet. For this reason, in the ventilation control of the first embodiment, when the south wind is blowing, the remaining one window 4 that is opened is the first wall 31 or the third wall 35 that is unlikely to be subjected to negative pressure. The window 41 or the third window 43 is used.

  In summary, in the ventilation control of the first embodiment, when the south wind is blowing, any one window 4 of the first window 41 or the third window 43, the second window 42, the fourth window 44, and Any one of the fifth windows 45 is opened. Similarly, when the west wind is blowing, any one window 4 of the second window 42 or the fourth window 44 and any one of the third window 43, the first window 41, and the fifth window 45 are displayed. 4 is opened. When the north wind is blowing, any one window 4 of the first window 41 or the third window 43, and any one window 4 of the second window 42, the fourth window 44, and the fifth window 45, Is opened. When the east wind is blowing, any one window 4 of the second window 42 or the fourth window 44, and any one window 4 of the third window 43, the first window 41, and the fifth window 45, Is opened. As described above, the fifth window 45 tends to be the window 4 functioning as an outlet in any of the south wind, the west wind, the north wind, and the east wind. For this reason, it is possible to open the fifth wall 35 as an outlet, open the window 4 formed on one of the remaining four walls 3, and close the remaining window 4 by the ventilation control. It is valid.

  In the first embodiment, since the house 2 has a square shape in plan view, the deviation due to the directionality of the wind direction is small. That is, when the house 2 has a rectangular shape in plan view, the airflow inside the house 2 differs depending on whether it is a south or north wind and an east or west wind. On the other hand, when the house 2 has a square shape in plan view, there is no difference between the south wind, the north wind, the east wind, and the west wind.

  Further, in the ventilation control in cases other than the above, the direction in which the wind blows (upstream direction) and the direction in which any window 4 faces (that is, the direction in which the outward normal of the wall 3 on which the window 4 is provided). The window 4 having the smallest angle is defined as the window 4 functioning as an inflow port. When there are a plurality of windows 4 having the smallest angle, the arbitrary window 4 is used as a window 4 that functions as an inflow port. Furthermore, let the window 4 formed in the one wall 3 adjacent to the wall 3 in which this window 4 is provided be the window 4 which functions as an outflow port.

  As described above, by opening the two windows 4 formed on the two adjacent walls 3 and closing the three windows 4 formed on the remaining three walls 3, the airflow is generated from the windows 4 into which the airflow flows. The flow path resistance to the flowing-out window 4 is reduced, and it is easy to increase the air flow rate. Thereby, it becomes easy to effectively cultivate and grow plants including agricultural products.

  A second embodiment will be described with reference to FIGS. In addition, since 2nd embodiment is the same as 1st embodiment in most, since the same code | symbol is attached | subjected about the same part and description is abbreviate | omitted, it mainly demonstrates a different part.

  As shown in FIGS. 5 and 6, the agricultural house 1 according to the second embodiment includes a wind speed detector 82 that detects the wind direction around the house 2. The wind speed information detected by the wind speed detector 82 can be acquired and processed by the control device 7. In this case, the wind speed detector 82 may be supplementarily provided with necessary devices such as an amplifier and an A / D converter.

  In the ventilation control, not only the wind direction information but also the wind speed information detected by the wind speed detector 82 is further added to determine how to open and close the five windows 4. For example, when the wind speed is a certain value or more, the direction in which the wind blows (upstream direction) and the direction in which any window 4 faces (that is, the outward normal of the wall 3 on which the window 4 is provided) And the window 4 with the smallest angle is closed. Then, by opening the window 4 on the wall 3 opposite to the window 4 as an inflow port, it becomes easy to prevent the air flow rate from becoming excessively large.

  As described above, by providing the agricultural house 1 with the wind speed detector 82, it is possible to perform more various controls as compared with the case where only the wind direction detector 81 is provided.

  Moreover, the agricultural house 1 is provided with the external temperature thermometer 83 which detects the wind direction around the house 2, as shown in FIG. 5, FIG. The wind speed information detected by the outside air thermometer 83 can be acquired and processed by the control device 7. In this case, the outside air thermometer 83 may supplementarily include necessary devices such as an amplifier and an A / D converter.

  In the ventilation control, not only the wind direction information but also the outside air temperature information detected by the outside air thermometer 83 is further added to determine how to open and close the five windows 4. As described above, when the agricultural house 1 includes the outside air thermometer 83, more various controls can be performed as compared with the case where only the wind direction detector 81 is provided.

  Moreover, the agricultural house 1 is provided with the external air hygrometer 84 which detects the wind direction around the house 2, as shown in FIG. 5, FIG. The outside humidity information detected by the outside humidity meter 84 can be acquired and processed by the control device 7. In this case, the outside air hygrometer 84 may be supplementarily provided with necessary devices such as an amplifier and an A / D converter.

  In the ventilation control, not only the wind direction information but also the outside air humidity information detected by the outside air hygrometer 84 is further added to determine how to open and close the five windows 4. As described above, when the agricultural house 1 includes the outdoor air hygrometer 84, more various controls can be performed as compared with the case where only the wind direction detector 81 is provided.

  Moreover, the agricultural house 1 is provided with the thermometer 85 in a house which detects the wind direction around the house 2, as shown in FIG. 5, FIG. The in-house temperature information detected by the in-house thermometer 85 can be acquired and processed by the control device 7. In this case, the in-house thermometer 85 may additionally include necessary devices such as an amplifier and an A / D converter.

  In the ventilation control, not only the wind direction information but also the house temperature information detected by the house thermometer 85 is further added to determine how to open and close the five windows 4. As described above, by providing the agricultural house 1 with the in-house thermometer 85, it is possible to perform more various controls as compared with the case where only the wind direction detector 81 is provided.

  Moreover, the agricultural house 1 is provided with the in-house hygrometer 86 which detects the wind direction around the house 2, as shown in FIGS. The in-house humidity information detected by the in-house hygrometer 86 can be acquired and processed by the control device 7. In this case, the in-house hygrometer 86 may be supplementarily provided with necessary equipment such as an amplifier and an A / D converter.

  In the ventilation control, not only the wind direction information but also the house humidity information detected by the house hygrometer 86 is further added to determine how to open and close the five windows 4. Thus, by providing the house 1 for agriculture with the in-house hygrometer 86, it is possible to perform more various controls as compared with the case where only the wind direction detector 81 is provided.

  Note that the wind speed detector 82, the outside air thermometer 83, the outside air hygrometer 84, the house inside thermometer 85, and the house inside hygrometer 86 are used (provided) together with the wind direction detector 81 in any combination to provide ventilation. Control may be performed.

  Example 1 Wind direction is east (windward is east), wind speed is 2.0 m / s, house temperature is 30 ° C., house humidity (relative humidity) is 70%, outside air temperature is 25 ° C., outside air humidity ( When the relative humidity is 50%, the fourth window 44 and the fifth window 45 are opened.

  (Example 2) Wind direction is south (windward is south), wind speed is 3.0 m / s, house temperature is 35 ° C., house humidity (relative humidity) is 60%, outside temperature is 30 ° C., outside humidity ( When the relative humidity is 40%, the first window 41 and the fifth window 45 are opened.

  A third embodiment will be described with reference to FIG. Since the third embodiment is mostly the same as the second embodiment, the same portions are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

  As shown in FIG. 7, the agricultural house 1 according to the third embodiment has a plurality of agricultural houses 1 according to the second embodiment shown in FIGS. 5 and 6.

  It is difficult for wind to flow between two adjacent agricultural houses 1, and even if the window 4 provided on the wall 3 on the side close to the agricultural house 1 is opened, it is difficult to ensure the air flow in the house 2.

  That is, when the east wind is blowing, the 1st window 42, the 3rd window 44, and the 5th window 45 are easy to function as an outflow port, and the 2nd window 42 and the 4th window 44 are easy to exhibit the function as an inflow port. . In particular, the fourth window 44 is more likely to function as an inflow port than the second window 42. However, since the fourth window 44 is provided on the wall 3 on the side close to another agricultural house 1, the fourth window 44 is provided on the wall 3 on the side close to another agricultural house 1 instead of the fourth window 44. The second window 42 that is not open is opened.

  Thus, in the third embodiment, the house 2 is determined by determining the window 4 to be opened from the remaining windows 4 without opening the window 4 provided on the wall 3 on the side close to another agricultural house 1. It becomes easy to secure the amount of ventilation inside.

  In addition, in 1st embodiment thru | or 3rd embodiment, although the agricultural house 1 is mainly used for agriculture, livestock, a residence, others may be sufficient, and a use is not specifically limited.
