DETAILED DESCRIPTION OF THE INVENTION

[0009] Each embodiment will be described in detail below with reference to the accompanying drawings. Note that the dimensional ratios in the drawings are merely examples and are not limiting. Furthermore, shapes and the like in the drawings may be partially exaggerated for the sake of explanation. Furthermore, in the drawings, for ease of viewing, reference symbols may be assigned only to some of the parts that exist with the same attribute.

[0010] FIG. 1 is a diagram showing a schematic top view of a place where the outdoor air blowing method, outdoor air blowing device, and panel according to this embodiment are suitable for application.

[0011] Fig. 1 shows a construction site 90, and in the example shown in Fig. 1, the construction site 90 faces a road 3 on the south side. Note that construction sites to which this embodiment is applicable do not necessarily have to face a road, and may face the road in any direction. Note that in Fig. 1, reference numeral 4 indicates a sidewalk.

[0012] The construction site 90 is surrounded by a temporary fence 7. The temporary fence 7 is placed so as to surround the construction site 90. In other words, the temporary fence 7 has the function of dividing the space related to the construction site 90. The temporary fence 7 is removed once work at the construction site 90 is completed.

[0013] In the following, the inside of the temporary fence 7 refers to the side of the construction site 90, and the outside of the temporary fence 7 refers to the outside of the construction site 90 (i.e., the side of the road 3).

[0014] The temporary fence 7 is generally set up slightly offset toward the sidewalk 4 from the construction site 90, but the boundary position is arbitrary. For example, the temporary fence 7 may be set up along the boundary line between the construction site 90 (the land related to the construction site 90) and the sidewalk 4. In the example shown in FIG. 1, the temporary fence 7 is equipped with a gate 8 that allows vehicles to enter and exit. The gate 8 is slidable horizontally and can be opened and closed by sliding. When the gate 8 is opened, vehicles can enter and exit between the construction site 90 and the road 3. When the gate 8 is closed, vehicles cannot enter or exit between the construction site 90 and the road 3. The temporary fence 7 may be equipped with doors that allow people to enter and exit, signs, digital signage, etc.

[0015] Figure 2 is a cross-sectional view taken along line AA in Figure 1. In Figure 2, the letter G indicates the ground.

[0016] As shown in FIG. 2, the temporary fence 7 is securely supported by support members 79 on the construction site 90 side to prevent it from collapsing or the like.

[0017] In this embodiment, as shown in Fig. 2, a spot cooler 50 is provided on the construction site 90 side of the temporary fence 7. The spot cooler 50 itself may have any configuration and may be a normal commercially available product.

[0018] The spot cooler 50 is a device that generates cool air and can blow out the cool air through an end opening of the tubular member 51. In a modified example, a device that can blow out warm air or mist may be used instead of the spot cooler 50. For example, in the bitterly cold winter season, a device that can blow out warm air may be used.

[0019] Fig. 3 is a plan view showing the panels 70 that form the temporary enclosure 7. In Fig. 3, the up-down direction indicates the up-down direction (vertical direction) in the installed state.

[0020] The temporary fence 7 is formed by connecting multiple panels 70. The multiple panels 70 are long in the vertical direction, and are joined together without gaps by connecting their horizontal ends. The multiple panels 70 are made of metal, but may also be made of other materials (for example, wood or resin).

[0021] Fig. 4 is a plan view showing a panel 70 having ventilation holes 710. In Fig. 4, the up-down direction indicates the up-down direction (vertical direction) in the installed state.

[0022] In this embodiment, the multiple panels 70 forming the temporary enclosure 7 include a panel 70 having a ventilation hole 710 (hereinafter, for the sake of distinction, also referred to as a "perforated panel 71"). The perforated panel 71 is only a part of the multiple panels 70 forming the temporary enclosure 7.

[0023] The ventilation holes 710 in the perforated panel 71 have a ventilation function of directing cool air from the spot cooler 50 to the outside of the temporary fence 7. For this purpose, the spot cooler 50 is positioned relative to the perforated panel 71 so that the end opening of the tubular member 51 faces (communicates with) the ventilation holes 710. In this case, the tubular member 51 itself may extend to the outside of the temporary fence 7 through the ventilation holes 710, but preferably the tubular member 51 itself is located inside the temporary fence 7. This makes it difficult to access the tubular member 51 from outside the temporary fence 7, preventing tampering such as throwing foreign objects into the tubular member 51.

[0024] The diameter of the ventilation holes 710 is arbitrary as long as it can provide a ventilation function for the cool air from the spot cooler 50, but it is preferably approximately the same as the diameter of the end opening of the tubular member 51 of the spot cooler 50.

[0025] FIG. 5 is a cross-sectional view of the spot cooler shown in FIG. 2, illustrating an example of an operating state of the spot cooler 50. As shown in FIG.

[0026] When the spot cooler 50 is in operation, the cool air from the spot cooler 50 is blown out to the outside of the temporary fence 7 through the ventilation holes 710 (see arrow R5 in FIG. 5). In the example shown in FIG. 5, a worker is standing outside the temporary fence 7 in front of the perforated panel 71. In the situation shown in FIG. 5, the worker is managing vehicles entering and exiting gate 8 under the scorching sun. The worker can wait when gate 8 is closed, for example, and stand in front of the perforated panel 71 to receive the cool air. This can protect workers who work in harsh environments exposed to direct sunlight and reflected light (see R6 in FIG. 5) and radiant heat from the asphalt or other ground surfaces from health hazards such as heatstroke.

[0027] The perforated panel 71 is preferably provided adjacent to the gate 8 of the construction site 90. This increases the opportunity and time for workers (e.g., security guards) working near the gate 8 of the construction site 90 to be exposed to cool air.

[0028] The perforated panels 71 may be arranged parallel to the extension direction of the road 3 in a top view, but are preferably arranged at an angle relative to the road 3 in a top view. That is, the temporary fence 7 is offset toward the construction site 90 near the gate 8, and the panels 70 are arranged at an angle to form this offset. By arranging the perforated panels 71 as such panels 70, the perforated panels 71 can be arranged at an angle relative to the road 3 in a top view. In this case, cool air from the ventilation holes 710 can flow diagonally toward the gate 8 in a top view, allowing cool air to be efficiently delivered to workers waiting at the edge of the gate 8. Note that diagonally arranged panels 70 are provided on both sides of the gate 8, and only one of them may be formed by the perforated panels 71, or both may be formed by the perforated panels 71.

[0029] The ventilation holes 710 of the perforated panel 71 are preferably provided at a height corresponding to the waist height of a worker of average height. This makes it easier to send cool air directly to the fan 40 of the fan-equipped workwear worn by the worker. This is because the fan 40 tends to be provided near the waist of the fan-equipped workwear worn by the worker. In a modified example, the perforated panel 71 may be provided with multiple ventilation holes 710 at different heights. In this case, the height of the cool air outlet can be changed depending on the height of the worker and the height of the fan 40. Alternatively, the ventilation holes 710 may be elongated in the vertical direction to accommodate the height of the worker and the height of the fan 40.

[0030] Incidentally, the ventilation holes 710 of the perforated panel 71 may be holes without any cover, but in this case, when viewed from outside the temporary enclosure 7, they will be recognized as simple holes, and there is a possibility that someone other than the relevant parties may reach in out of curiosity or insert a foreign object. For example, they may mistake them for the opening of a trash can.

[0031] Therefore, in this embodiment, a mesh-like or louver-like member is preferably provided in a manner that does not impair the necessary ventilation in the ventilation holes 710 of the perforated panel 71. This ensures that the ventilation holes 710 are shielded from the outside, and prevents problems such as the introduction of foreign matter.

[0032] 6 to 8 are explanatory diagrams showing cover members 30 to 32 that may be provided in the ventilation holes 710 of the perforated panel 71. Figures 6 and 7 are plan views of the cover members 30 and 31 as viewed in the direction perpendicular to the surface (perpendicular to the perforated panel 71), and Figure 8 is a cross-sectional view of the louver structure of the cover member 32.

[0033] 6, the cover member 30 is provided so as to cover the ventilation hole 710, but by having the regularly arranged round holes 300, the necessary ventilation is ensured. The size and density of the round holes 300 may be adapted in consideration of the balance between the necessary external blocking properties and the necessary ventilation (loss in flow). The cover member 30 is made of metal, but may also be made of a resin material or the like.

[0034] 7, the cover member 31 is provided so as to cover the ventilation holes 710, but the regularly arranged lattice holes 310 ensure the necessary ventilation. The size and density of the lattice holes 310 may be adjusted in consideration of the balance between the necessary external blocking properties and the necessary ventilation properties (flow loss). The cover member 31 is made of metal, but may also be made of a resin material or the like.

[0035] In the example shown in Fig. 8, the cover member 32 is provided with louvers 322 that can be opened and closed. In this case, the louvers 322 may be opened and closed manually or electrically. The louvers 322 are opened when the spot cooler 50 is in operation, thereby ensuring the necessary ventilation. Furthermore, the louvers 322 are closed when the spot cooler 50 is stopped, thereby improving the ability to block out external elements.

[0036] Figures 9 and 10 are schematic diagrams showing an example of the mounting structure of the lid member 30. Figure 9 is a plan view of the area around the ventilation holes 710 in the perforated panel 71 as viewed in the direction perpendicular to the surface (perpendicular to the perforated panel 71), and Figure 10 is a cross-sectional view taken along line BB in Figure 9. Note that although the mounting structure of the lid member 30 will be described here, the mounting structures of the lid members 31 and 32 may be similar.

[0037] The lid member 30 may be fixed to the perforated panel 71 by welding or the like, or may be detachably fixed to the perforated panel 71 via an attachment structure shown in FIGS. 9 and 10 . In the example shown in FIGS. 9 and 10 , engaging members 712 and 713 with a C-shaped cross section are provided around the ventilation hole 710 in the perforated panel 71. The engaging member 712 is provided around the entire periphery of the ventilation hole 710 in the perforated panel 71, except for the upper side. The C-shaped cross sections of the left and right engaging members 712 open on the ventilation hole 710 side and support the edge of the lid member 30 so that it can slide up and down. The C-shaped cross section of the lower engaging member 713 opens upward and supports the edge of the lid member 30. This attachment structure allows the lid member 30 to be detachably supported (fixed).

[0038] Next, the control system of the spot cooler 50 will be described with reference to FIG.

[0039] The spot cooler 50 may be manually turned on / off or have its air volume adjusted by an operator or the like, or may be automatically controlled using the control device 20.

[0040] FIG. 11 is a configuration diagram showing an example of a control system when the control device 20 is used.

[0041] 11, in addition to the spot cooler 50, the control device 20 is communicatively connected to a user interface 22, an environmental sensor 24, a biological sensor 26, a monitoring camera 28, and an alarm device 52. The communicative connection may be any form using a wired network and / or a wireless network.

[0042] The control device 20 may be built into the spot cooler 50. The control device 20 is formed by a computer, and may realize various functions by having a built-in CPU (Central Processing Unit) execute one or more programs stored in a storage device.

[0043] The user interface 22 allows input by a user (e.g., an operator). The user interface 22 may be provided in the spot cooler 50 or may be provided separately from the spot cooler 50. For example, the user interface 22 may be realized by an app on a smartphone carried by the user. The control device 20 receives various instructions from the user via the user interface 22.

[0044] The environmental sensor 24 detects environmental information such as the ambient temperature and humidity. The environmental sensor 24 provides the environmental information to the control device 20. The environmental sensor 24 may be provided to acquire environmental information near the gate 8. The environmental sensor 24 may be carried (held) by a worker who is expected to be exposed to the cool air from the spot cooler 50.

[0045] The biosensor 26 acquires biometric information (such as pulse rate) of a user (such as a worker). The biosensor 26 may be realized by, for example, a wearable terminal.

[0046] The surveillance camera 28 is installed so as to capture images of the situation around the gate 8. For example, the surveillance camera 28 is installed so as to capture images of the front of the perforated panel 71 (outside the temporary fence 7).

[0047] The alarm device 52 outputs an alarm through sound and / or video. The alarm device 52 may be in the form of, for example, a patrol lamp or a buzzer.

[0048] In the example shown in FIG. 11, the controller 20 may control the spot cooler 50 in response to instructions from a user received via the user interface 22.

[0049] 11 , the control device 20 can control the spot cooler 50 and / or the alarm device 52 based on various information from the environmental sensor 24, the biological sensor 26, and the monitoring camera 28. For example, the control device 20 may turn on or maximize the output of the spot cooler 50 when a worker is located within the range of cool air from the spot cooler 50 based on an image from the monitoring camera 28. The control device 20 may maximize the output of the spot cooler 50 when an environment with a high risk of heatstroke is detected based on environmental information from the environmental sensor 24. The control device 20 may maximize the output of the spot cooler 50 when a user state with a high risk of heatstroke is detected based on biological information from the biological sensor 26. In this case, the control device 20 may consider the positional relationship between the range of cool air from the spot cooler 50 and the worker based on an image from the monitoring camera 28. For example, the control device 20 may be configured to output an alarm 52 when the worker is away from the area where the cool air from the spot cooler 50 hits, based on an image from the monitoring camera 28.

[0050] Although each embodiment has been described in detail above, it is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the claims. It is also possible to combine all or a plurality of components of the above-described embodiments.

[0051] For example, in the embodiment described above, the spot cooler 50 is provided in relation to the location of the gate 8, but the location of the spot cooler 50 (and therefore the perforated panel 71) is arbitrary. In addition, the spot cooler 50 (and therefore the perforated panel 71) may be provided at a location other than the construction site 90.
